Market overview

Five major forces continue to shape the UK banking market

**Increased market disruption and strong competition**

**What we have seen**

The market in which we operate is highly competitive. We expect such competition to intensify in response to increasing entry of FinTech and BigTech firms in the banking sector as well as the growth of digital currencies and cryptocurrencies. Traditional UK banks have largely refocused on core business areas and improving their digital offerings.

**Our response and looking ahead**

We remain cognisant of the evolving competitive environment and continue to develop offerings to rival competitors and seek partnerships to develop new propositions. Banco Santander's PagoNxt offering incorporates simple and accessible digital payment solutions. This is a key area for growth alongside OpenBank, their 100% digital bank. We expect these to be rolled out across Europe in the future. Neo-banks continue to gain market share, competing with traditional UK banks. Nevertheless, financial sustainability remains unproven for most. Those that have started to highlight emerging signs of profitability have tended to mirror more traditional banking models. Nevertheless, digital-only providers continue to disaggregate the traditional vertically integrated banking business model by targeting the most profitable elements with innovative new propositions and attracting significant valuations (for example buy-now-pay-later). Large international peers have also entered the UK market through new digital-only brands with limited product offerings; however may provide a competitive offering over the longer term.

**Climate change**

**What we have seen**

Climate change is one of the biggest challenges facing society and our industry has a critical role to help tackle this. Clear disclosure is essential to help markets and other stakeholders assess our climate performance.

**Our response and looking ahead**

Climate change is one of three pillars of our Sustainability and Responsible Banking Strategy; with the goal of supporting the transition to a low carbon economy as both a lender and an employer. We are working to meet the expectations set by the Bank of England, PRA and FCA. We are implementing the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), and taking action to meet the expectations set by the PRA, BoE and FCA. This requires wide-ranging collaboration both within the bank and externally to develop the tools and methodologies needed. As such, we have adopted a unified approach across the Santander UK Group Holdings plc group and therefore present TCFD disclosures on that basis in the Santander UK Group Holdings plc group Annual Report.

**Changing customer behaviour and distribution**

**What we have seen**

Customer interactions continued to shift to digital and remote services. Our enhanced digital capability attracted a further 370,000 digital customers in 2022, with 92% of current account and 99% of credit card openings made through digital channels.In mortgages, intermediary share of distribution continues to increase, whilst other products are now distributed largely through digital channels. 76% of our refinanced mortgages were retained online in 2022.

**Our response and looking ahead**

We invest in ensuring access to financial services for our customers, including those less confident in using technology for managing their finances.While customer footfall has fallen in recent years, we continue to appreciate the value of the human touch delivered through our branch network. We are mindful of the needs of our most vulnerable customers, responding with 'access to cash' solutions and providing mechanisms for help from a trusted third party. We continue to develop offerings to deliver growth through customer loyalty and customer experience. We are committed to creating products and services catered to our customers needs. In October 2022 we launched my Home Manager, designed to assist mortgage customers aspects of managing their home.

**Demanding regulatory agenda**

**What we have seen**

n 2022 the regulatory policy and change agenda remained intense. The UK Government announced the outcome of the Future Regulatory Framework review and has introduced legislation to Parliament to implement this, combined with a number of regulatory consultations aligned with the proposals.

**Our response and looking ahead**

This year we implemented the PRA's operational resilience and outsourcing expectations, and this remains a key focus area for the bank moving forward, up to the 2025 deadline. The PRA has also published its consultation on the implementation of Basel 3.1 which will impact capital requirements.The FCA announced the introduction of the Consumer Duty with tight implementation timelines, requiring significant focus across business units to ensure that we are compliant with the Duty, which has a first implementation date of 31 July 2023. We continue to engage with regulators on other key issues, such as APP fraud and the challenges around the rising cost of living and impact of interest rates rises. We await the Government's forthcoming consultation on ring fencing. We anticipate further intensive regulatory activity in 2023 and will continue to work with industry, trade bodies, regulators, and Government to support the appropriate regulation of the UK's financial services industry.

**Uncertain economic environment**

**What we have seen**

In 2022, inflationary conditions moved from a perceived transitory condition to a likely more longer-term and persistent high inflation environment, following the conflict in Ukraine. This has caused further increases in the cost of living for our retail customers, particularly those on lower incomes. Market expectations for Bank Rate also changed significantly with the Monetary Policy Committee (MPC) raising the rate from 10bps at the end of 2021 to 350bps by the end of 2022. The volatility in Q3 2022 caused mortgage rates to rise sharply.

**Our response and looking ahead**

Our business is correlated to the performance of the economy. Our purpose is to help people and businesses prosper, so we are committed to support our customers with the rising cost of living.Our focus has been to provide targeted and practical support, including advice on household budgeting and a toolkit for SMEs to help them through the ongoing inflationary pressures. The outlook remains uncertain as inflation has eroded real disposable income with the prospects of a recession ahead. We expect Bank Rate to continue to rise, peaking in H1 2023. Higher base rates are likely to dampen demand for housing, causing a fall in house prices back to 2021 levels. We reached out to over 2 million customers most likely to be impacted by the cost of living crisis and remain committed to helping our customers at moments that matter most.

Risk management overview

**Top risks**

Highlighted below are our Top risks in 2022 and associated management actions. Many of these risks are likely to remain in focus in 2023.

**Inflationary & supply chain pressures - New**

We introduced this as a Top risk following the onset of the conflict in Ukraine, which exacerbated already elevated inflation levels. This covers potential impacts on our customers from cost of living increases and rising interest rates; on our corporate customers from business cost increases and supply chain pressures. It also covers remaining Covid-19 and Brexit related risk issues, post pandemic and formal exit from the EU, which are now no longer separate Top risks. We have taken actions to adjust affordability criteria in our retail lending decisions, increase customer support capacity, and ensure close and continuous monitoring of our credit portfolios for any indications of stress in our customer base.

**Climate change**

We continue to enhance our data strategy and reporting reflecting the strategic importance of climate change risk. We continue to progress our climate change implementation plan, including integrating associated risks into our Risk Framework, formulating a risk appetite, and progressing associated initiatives.

**Financial Crime**

In December 2022, we accepted an FCA penalty of £108m relating to historical AML control shortcomings as described under Conduct & Regulatory below. Developments related to the implementation of Russian sanctions have added further complexity to mitigating compliance risks and maintaining operational resilience in our Financial Crime Centre of Excellence. We continue to enhance our financial crime risk management capabilities, through implementation of our Financial Crime Transformation and Remediation programme, enhancing controls, and providing additional analytics capacity and subject matter expertise.

**Fraud - New**

We recognised this as a Top risk, reflecting significant industry wide increases in Fraud levels and losses, which are impacting our customers. Fraud losses now consistently form a significant proportion of our operational losses. We have designed new fraud prevention tools to complement our existing prevention and detection systems and controls. We continue to deploy dynamic 'scam warning' in our online banking payment process, to enhance fraud prevention controls for high-risk digital payments.

**IT** 

The importance of IT risk management and control continued to be re-iterated by some outages to customer services during the year, although there has been a continued trend downwards in such incidents from H2 2021. To address these issues, we have finalised a multi-year IT Transformation plan, with Board approval, with the aim of securing risk reduction benefits which will accrue during the plan period. We consider that our IT associated risks are decreasing as a result of the ongoing implementation of our transformation plan.

**Cyber risk management**

In 2022, we experienced no notable data or cyber security incidents, although we responded to a number of third-party incidents, mainly ransomware attacks. Externally, the cyber risk landscape stabilised, however the threat remains at unprecedented levels due to the ongoing conflict in Ukraine. We continue to review and enhance our controls based on the latest intelligence, and invest in the right skills and resources. We also actively work with our peers in the Cyber Defence Alliance to share threat intelligence expertise, and experiences, to help identify common cyber-attack features and effective mitigation strategies.

**People** 

In 2022, we continued to focus our overall wellbeing and inclusion strategy on supporting colleagues through transformation and change. In line with our peers, we are experiencing a competitive recruitment market and responding with enabler plans to reduce time-to-hire and open vacancies, as well as maintaining capacity and capability to deliver our business plans. Cost of living is also a key focus area where we have intervened with pay rises to support our colleagues across the business. We have managed a gradual return of colleagues to office environments, along with hybrid working as well as the people risks associated with a phased relocation of our Head Office to Unity Place in Milton Keynes.

**Conduct & Regulatory** 

We continue to face a challenging regulatory agenda with significant ongoing FCA and PRA interaction on a range of industry issues, as well as the ECB and Payments Services regulators. These issues include the FCA's Consumer Duty, which requires considerable management and focus of resources. Final rules were published in July 2022, with the first implementation date set at 31 July 2023 and the final date of July 2024. In December 2022 the FCA announced that Santander UK accepted a penalty of £108m for historical AML control shortcomings between December 2012 and October 2017.

**Managing Complex Change**

We have a challenging change agenda including continued aspirations for transformation and growth. We have well-established change control processes, as well as a strong oversight framework and related risk-based prioritisation. This enables us to address operational and capacity challenges and facilitate timely delivery. In 2022, change included a reduction of our property footprint, and a specific focus on migration to cloud, further digitalisation, and management of obsolescence. Ensuring change does not result in adverse impacts on our risk profile underpins our strategic decisions and is robustly managed.

**Data management**

Data management, including data privacy, is a Top risk reflecting its role in supporting our business plans and strategy, as well as the rising cyber threat landscape and the importance of controls over personal data. In 2022, we continued to monitor data management risk through the enhanced governance structures and processes put in place by our Chief Data Officer. We are implementing a central data programme, with clear deliverables that will improve our data management capabilities in line with our approved data strategy.

**Third Party Risk Management (TPRM)**

We are progressing with a programme of work to enhance controls and governance arrangements. During 2022, we continued to evolve our processes, including implementation of a new TPRM process and amending contracts with suppliers. Our Procurement transformation also continues to operationalise our updated TPRM policies and processes.

**Ring-Fencing**

We have retained Ring-fencing as a Top risk to maintain our focus on ongoing governance and compliance, as we continue to assess and refine the quality and maturity of controls. Further review may be needed, depending on the outcomes of HM Treasury's proposed consultations on the ring-fencing regime, due to take place in 2023.

**Building and maintaining capital strength and Pension risk** 

We saw sustained resilience and improvement in our Regulatory capital and Pension fund metrics throughout 2022 with detailed analysis set out in the Risk review. Pension risk has now been removed as a Top risk as a result of those improvements in metrics and actions taken to reduce residual risk and enhance resiliency, given increased market volatility in 2022.

**Emerging risks**

Highlighted below are our emerging risks in 2022 and our associated management actions. All of these risks will likely be in focus in 2023, given that they continue to evolve and intersect with our Top risks.

**Uncertain macroeconomic and geopolitical environment**

In the past few years, a number of broader, more complex and uncertain risks have evolved which may present future headwinds. These include geopolitical tensions between regions across the world, in particular the current conflict in the Ukraine. This has impacted global energy prices and supply chains which added to inflationary pressures, as well as stretching household finances. These risks accelerate trends towards deglobalisation, and a reduction of variety of goods and services, causing prices to increase over the medium to long-term.

These factors are also playing into increased localised political risk across the globe, including in the UK with a second new Prime Minister in 2022. In February 2023, the First Minister of Scotland resigned, with future implications for the Union with the UK remaining uncertain. We are closely following these political developments and the potential for any material impacts which we may need to reflect in our business plans.

**Rapid technological change and customer behaviour**

Our multi-year transformation programme with a focus on investment in digitalisation and automation, is aimed at designing compelling propositions for targeted customer segments, reshaping customer interactions and simplifying and digitising the business at scale for improved efficiency and returns.

Our overall approach reflects the continued acceleration of strong trends towards customer digital adoption via mobile and online banking, whilst also ensuring that we remain competitive in a market which is experiencing an increase in digital-led market entrants. We are cognisant of cyber, cloud technology and operational resilience issues which we take into account in our development strategy.

**Intense market competition**

Enhancing our digital proposition remains key in supporting our customers' needs, retaining and growing our customer loyalty base, and addressing the commercial challenges of a highly competitive mortgage market, where surplus deposits in ring-fenced banks remain a key driver of market pricing. As well as the elevated competition between incumbent banks, new entrants backed by other large multi-national banks are also launching in the UK offering competitive incentives to compete in the growing digital market, as well as savings, lending and investment markets.

**Demanding regulatory agenda**

We remain vigilant in taking a customer-focused approach in developing strategy, products, services and policies that support fair customer outcomes and market integrity. Like all UK banks, we will continue to face a demanding and complex regulatory agenda in 2023 and beyond focused on consumer outcomes, customer vulnerability, competition, climate change and Consumer Duty.

The PRA's operational resilience and outsourcing expectations remains a key focus for the bank moving forward, as well as implementation of Basel 3.1 which will impact capital requirements. We also continue with regulatory engagement on other key issues such as APP fraud and the impacts of the rising cost of living and interest rate rises.

Looking ahead we await the government's forthcoming consultation on ring-fencing, as well as working with industry, trade bodies, regulators and the government to support the appropriate regulation of UK financial services.

**Extended Government involvement in banking & markets**

Following Government policy interventions during the Covid-19 pandemic, including UK Government guaranteed loans and dividend restrictions, there are some indications that this trend will continue moving forwards. The increase in environmental, social and governance factors is likely to direct banks' lending decisions further, with the risks of higher capital requirements as an incentive to channel lending to certain sectors, and potentially restrict or avoid others. Banks may also be called upon to contribute more to the exchequer, due to stretched public finances, via increased taxation rates, or windfall taxes, as evidenced by recent actions in Spain. Product pricing and actions will also remain under intense scrutiny by regulators and the Government, during the current period of higher inflation and mortgage rates. These issues have the potential to significantly impact our business plans, costs and revenues.

**Central Bank Digital Currencies & Crypto assets**

Depending upon how these are implemented, there is a risk of a significant transfer of commercial bank deposits into these Central Bank Digital Currencies over time, increasing wholesale funding requirements and costs, and reducing the 'stickiness' of deposits in a stress. There are also broader potential impacts on regulatory frameworks, and monetary and fiscal policy. We continue to monitor these developments as they evolve. We are also addressing the risk of crypto asset exposure through our client onboarding policies and procedures, which are part of our Financial Crime framework.

**Disruption of UK macroeconomic factors**

**In the last quarter of 2022 and early 2023, UK house price growth slowed, following shocks to the macroeconomic environment arising from the conflict in Ukraine, which exacerbated inflationary pressures, and triggered significant rises in the cost of living and interest rates globally. After a steady increase of financial pressures on customers, the financial markets and economic environment saw substantial dislocation in H2 2022, which fundamentally changed macro-economic expectations for 2023 and beyond. We have been actively monitoring customer behaviour and to date our customers are showing resilience in adapting to the changing environment.**

In 2022, we significantly developed our regulatory models, focusing on capital adequacy, to comply with new regulatory technical standards for banks. We expect this trend to continue over the next two years in line with supervisory expectations.

We recognise that Model risks have increased in the current environment of both higher inflation and interest rates, which is inconsistent with the period upon which the models were developed. We have fed back our response to the PRA on how we meet policy and procedure requirements under the Model Risk consultation paper (CP6/22), including the independent review of judgemental adjustments.

There are also significant macroeconomic risks attached to the transition process of decarbonising industrial sectors, although we have very limited direct exposure to those in our Corporate and Commercial Banking clients' businesses. There are also costs and risks associated with reducing UK housing emissions and 'greening' commercial property which could impact our retail customers and corporate clients.

**Eurozone/Sovereign Bank Contagion**

We previously considered this risk as part of the uncertain macroeconomic and geopolitical environment, but have now identified it separately, given developments in 2022. Energy and commodity price shocks have increased risks to post-pandemic growth and financial conditions in the Euro area and globally. Euro area sovereigns, corporates and households face higher interest rates and cost pressures that could test debt sustainability for more highly indebted entities. The most relevant risks for Santander UK could be reflected in wider credit spreads which could increase wholesale funding costs. Credible funding plans and liability strategies to support our aspired business growth will be key, which are the subject of regular review, challenge and discussion at our ALCO.

Financial overview

**Development and performance of our business in 2022**

Information on the development and performance of our business in the year is set out in the 'Income statement review' section of the Financial review.

**Our position at 31 December 2022**

Information on our position at the end of the year is set out in the 'Balance sheet review' section of the Financial review.

Sustainability review

We recognise that financial institutions have an important role to play in addressing sector-specific challenges such as financial inclusion and financial crime, as well as broader systemic issues such as climate change.

We strive to create value for all our stakeholders, by delivering on our commitment to be a more responsible bank. This section is designed to be read together with our Environmental, Social and Governance (ESG) Supplement.

**Customers** 

**Cost of living**

2022 saw a sharp increase in the cost of living. We recognise that our customers may be feeling financial pressure brought on by these rising costs and higher mortgage interest rates.

In response, we updated the financial support pages on our website to offer financial health checks, budget planning tools and tips on cutting spending and navigating rising energy costs. We also communicated with more than two million customers most likely to be impacted to highlight the support available. Where appropriate, we give links to PayPlan, a free and independent debt advice provider.

**Financial inclusion**

Financial inclusion is an important issue; starkly illustrated by the 1.5 million people in the UK without a bank account and 13.1 million people with low financial capability. Our Financial Inclusion strategy is designed to help people improve their financial skills, gain access to financial services and develop financial resilience. The strategy has three pillars: financial education and knowledge; an inclusive portfolio of products; and, services and customer care.

**Meeting our customers' changing needs** 

Responding to trends in customer behaviour, we changed our branch opening hours in 2022 and increased telephone support available.

**Ongoing non-financial support for SMEs**

Santander Breakthrough continues to develop new tools, resources and programmes to help small and medium-sized enterprises (SMEs) with non-financial support that meets their needs when they need it most. The economic environment was challenging for SMEs and throughout 2022 we increased on-demand resources and skills development programmes available via santanderbreakthrough.co.uk. We ensure there is a balance of information for every business, whether they are looking to expand domestically or internationally, develop new ways of working or manage the rising costs of doing business.

**Shareholders**

**Part of a global bank**

We are a subsidiary of Banco Santander SA and our ordinary shares are all held by Banco Santander group companies and are not listed. Santander UK plc's preference shares are listed on the London Stock Exchange and we also have other equity instruments in the form of AT1 securities.

**Consistent shareholder returns**

Our operations are consistently profitable and we have paid a dividend every year since 2008. Dividends are paid in line with our dividend policy following review and approval by the Board. This ensures that our capital strength and resilience is maintained.

**Investor engagement**

Our Investor Relations team actively engages with institutional investors globally, working alongside our funding and capital teams for new issuances and building and maintaining relationships with fixed income investors and analysts.

We engaged with investors through in-person and virtual meetings, roadshows conferences, events and via regulatory announcements.

**People** 

**Culture**

We are part of a global company, united by a common culture, *The Santander Way*. This encompasses our purpose to help people and businesses prosper, our aim, to be the best open financial services platform, acting responsibly and earning the trust of our people, customers, shareholders and communities, our Simple, Personal and Fair values, our risk culture, which stresses that risk management is everyone's job, and our behaviours.

**Inclusion and belonging**

We aim to be a place where all of our people feel they belong and are supported to succeed. We're committed to being a truly inclusive organisation, one that reflects the customers and communities we serve. This commitment is backed up by our Everyday Inclusion strategy which prioritises the themes of intersectionality, respect, balanced representation, leadership, advocacy, allyship, transparency and accountability.

**Wellbeing** 

Wellbeing is essential to helping our employees thrive. Our comprehensive approach involves supporting mental, physical, social and financial wellbeing. Our internal Wellbeing Hub provides information on wellbeing topics and brings together all the support options we offer. The Hub has been accessed 160,000 times in two years.

**Fair pay and transparency**

In 2022, we took action to relieve cost of living pressures on our people. This included an exceptional salary increase of 4% for 60% of our workforce. This covered 11,000 colleagues in lower pay bands and was in addition to our usual annual pay review. This was part of the annual review of our reward framework, which checks that all salary reviews and changes to reward policies do not have an adverse impact on particular employee groups.

We are transparent about pay and benefits and are proud to have been an accredited Real Living Wage employer since 2015. All salary ranges and pay progression arrangements are visible to all colleagues. We voluntarily publish our Ethnicity Pay Gap within our annual Everyday Inclusion and Pay Gap Report. We also voluntarily disclose our CEO pay ratio in the Remuneration Implementation Report within this Annual Report.

**Communities** 

**Financial education**

Financial education is one of the pillars of our Financial Inclusion strategy. We believe it is crucial to provide a solid financial education to all children and young people, ultimately ensuring financial education for all. This is why we have a goal to become a leader in financial education by 2025. More information on our approach to financial inclusion is provided in the better communities section of our ESG Supplement.

The importance of financial education in the UK has been highlighted by the 2021 Strategy for Financial Wellbeing developed by the Money and Pensions Service, an arms-length Government body. The strategy's goal is to ensure an additional 2 million children and young people get a meaningful financial education by 2030, growing from 4.8 million to 6.8 million.

We have worked with experts who told us the best way to deliver financial education is to teach financial concepts to people when they are young. This helps them to make better decisions about their money and protect their finances later in life. As a result, we support financial education being compulsory in UK primary schools and for resources to be easily accessible for all teachers, parents and students across the UK. In 2022, we provided financial education to 1,292,724 young people.

**Santander Foundation**

In 2022 the Santander Foundation awarded £1.85m to 13 charities as part of its Financial and Digital Empowerment Fund. These new partners will receive grants ranging from £125,000 to £150,000 over the next three years to deliver services that will empower people with skills, support and confidence needed to improve digital and financial capabilities.

**Santander Universities** 

In 2022 we launched a new scholarship, skills and entrepreneurship programme designed to fuel the success of new generations of university students from underrepresented groups. Through the programme we aim to remove barriers to entry into higher education for these groups, level the currently uneven playing field and build essential skills for the future to ensure employment outcomes match peers from outside these groups. To achieve these aims, we will continue working with our established university partners to increase opportunities for underrepresented students, whether through our scholarships, living wage internships that help students focus on their future, or specialist entrepreneur centres to help turn students' passion projects into businesses. In 2022 we provided more than 8,000 scholarships and awards. At the heart of the initiative is a £1m scholarship scheme that will help 100 students from under-represented groups with annual grants of £10,000 over three years at our 75 university partners.

**Macmillan Cancer Support 2022-2024**

There are currently three million people living with cancer in the UK and one in two of us will receive a cancer diagnosis in our lifetimes. In June 2022, we launched a new strategic charitable partnership with Macmillan Cancer Support. The partnership aims to improve financial inclusion and support to help people to cope with financial challenges they face after receiving a cancer diagnosis. Since the launch, we have been working with Macmillan to review our processes, services and customer feedback to identify areas for improvement. We are developing a referral programme to connect our customers with Macmillan's support services. In addition to these strategic workstreams, we have raised over £455,000 including matched donations from the Santander Foundation.

**Ukraine support**

Since the conflict in Ukraine in February 2022, we have been working to support the humanitarian relief effort. Santander UK (including customers, colleagues and the Santander UK Foundation) supported a Banco Santander initiative to aid Ukraine with Santander UK contributing over £455,000 to the Red Cross and UNHCR. In addition, our colleagues can still benefit from 70 hours of matched volunteering time, which was originally doubled from 35 hours during Covid-19, but has been kept open due to the new crisis.

**Climate and Ethics**

**Responsible lending**

As part of the Banco Santander group, we comply with the Equator Principles to factor social, ethical, and environmental impacts into our risk analysis and decision making for qualifying financial transactions.

Our Reputational Risk policy and Environmental, Social and Climate Change (ESCC) policy covers oil and gas, power generation and transmission, mining and metals, and soft commodities. It also covers projects or activities within certain sectors located in areas classified as Ramsar Sites, World Heritage Sites or Category I, II, III or IV sites defined by the International Union for Conservation of Nature.

Our ESCC policy also prohibits project-related financing for new coal-fired power plant (CFPP) worldwide and we will only work with new clients with CFPPs to provide specific financing for renewable energy projects. In these exceptions, we expect the client to have a credible plan with verifiable targets that show the client will reduce its revenues from coal-powered generation to 10% or below by 2030. Currently, we have no exposure to CFPPs.

At 31 December 2022, Santander UK's exposure to fossil fuel sectors was only 0.4% of our total non-financial corporate lending. In line with Banco Santander's 2050 net zero commitment, by 2030 we will eliminate all exposure to thermal coal mining and not provide financial services to power generation clients with more than 10% of revenue from thermal coal. For more on Banco Santander's commitment and approach to carbon-intensive sectors, please see Banco Santander's Climate Finance Report 2021-2022.

We review all relationships and transactions with identified ESCC or reputational risks, including human rights, to ensure they are within our risk appetite. Key decisions can be escalated to the Reputational Risk Forum and, if needed, the Board.

**Green finance**

Banco Santander's Sustainable Finance Classification System (SFCS) defines what investments can be considered green or social financing. We have applied the SFCS to our lending and identified the following as green financing: renewable energy and other green energy financing; mortgages on properties with A- or B-rated energy performance certificates (EPC); and, financing for electric vehicles, hybrid and PHEV with emissions below 50g CO2/km.

The SFCS uses harmonised definitions that provide consistency in tracking, reporting and managing sustainable finance across Banco Santander group. For more on our green finance ambition and performance, see TCFD in the Sustainability and Responsible Banking section in the Santander UK Group Holdings plc Annual Report.

**Economic crime**

Our Anti-Financial Crime strategy seeks to deter, detect and disrupt financial crime. All colleagues receive mandatory economic crime training that highlights issues and risks across all types of financial crime. We continue to enhance our award-winning Anti-Financial Crime Academy (AFCA) to deliver targeted, role-specific training. This includes specialist Academies for operational capabilities and business lines performing key anti-financial crime controls, as well as formal training and competence measurement to ensure employees show the required anti-financial crime skills. We have completed our annual Learning Needs Analysis which provides a key input for determining our 2023 anti-financial crime training plan and strategy. By the end of 2022, 60,474

AFCA modules covering all AFC disciplines have been completed by 16,078 individuals across Santander UK.

To enhance recognition for those taking AFCA training, we are working with a leading industry body, the International Compliance Association (ICA), to obtain accreditation for AFCA curriculum modules. This will provide an AFCA-ICA certification to employees passing AFCA modules.

We maintain strong processes for anti-bribery and corruption and facilitation of tax evasion, in particular risk management measures for relationships with third parties. In 2022, we reaffirmed our senior executive commitment against facilitation of tax evasion by issuing our pledge to all colleagues. We continue to work with external partners to understand and develop best practice integrity standards and we remain a Transparency International UK Business Integrity Forum Gold Member.

Economic crime also includes protecting our customers from fraud. Further information can be found in our ESG Supplement.

**Streamlined Energy and Carbon Reporting** 

In 2022, we used 102,882,982 kWh of energy, a 14% reduction against 2021 (119,562,413 kWh). Greenhouse gas emissions (market-based) were 5,695 tCO2e,10% down from 2021 (6,321 tCO2e). Emissions per employee equate to 0.31 tCO2e in 2022, a decrease from 0.35 tCO2e in 2021. The basis of reporting of SECR information can be found in the TCFD section under Environmental Performance of the Santander UK Group Holdings plc group Annual Report.

---

| | | | |
|:---|:---|:---|:---|
| | 2022 | 2021 | 2020 |
| Scope 1 tCO2e  | 4512 | 6074 | 5937 |
| Scope 2 tCO2e - Location-based | 15571 | 18860 | 22014 |
| Scope 2 tCO2e - Market-based | 0.4 |  |  |
| Scope 3 tCO2e - business travel only | 1183 | 247 | 515 |
| Total emissions per employee (tCO2e/FTE) | 0.31 | 0.35 | 0.31 |

---

With the easing of Covid-19 travel restrictions, business travel increased in 2022. This resulted in higher Scope 3 emissions compared to 2021. The total distance travelled and related emissions remain significantly below pre-pandemic levels. Our total emissions fell in 2022 due to significant reductions in our gas and electricity consumption. This was largely due to the rationalisation of our office network.

We continue to actively manage energy performance across all sites, identifying opportunities to enhance efficiency and optimise energy use. Ongoing energy saving refurbishments include new LED lighting, HVAC upgrades and replacement of fan coil units. Go Green, our environmental engagement initiative for employees gives them practical energy saving tips which help to reduce our energy consumption

Stakeholder voice

The Directors are committed to ensuring that they take into account the likely impact of any decision in the long-term, as well as the interests of our stakeholders. The Board has identified our customers, employees, regulators, communities and investors as our key stakeholder groups on the basis of their importance in ensuring the continuing success of the Company. Balancing the interests of these five stakeholder groups alongside the interests of the Company is key to ensuring that we operate as a sustainable and responsible business, in line with our strategy.

To support the Board and its Committees in their considerations, in 2022 the Corporate Governance Office provided training on how to write good board papers to circa 300 senior members of management. This training included a specific focus on the directors' duties and how management's preparation of their papers plays a key role in ensuring that the Directors can discharge their responsibilities in a fully informed manner. In addition, the proforma paper, which management is required to use for their Board papers, now includes a section on stakeholder considerations. Details of the key issues that we took into consideration in relation to each stakeholder group in 2022 are set out below. The Board delegates a number of matters to its Committees. and more details and examples of stakeholder considerations taken in 2022 can be found in our Committee Chairs reports, particularly the Board Responsible Banking Committee Chairs' Report, in the Santander UK Group Holdings plc 2022 Annual Report which does not form part of this report.

Sustainability and Responsible Banking

Banco Santander has set out commitments to be a net zero bank by 2050. We are implementing the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), and taking action to meet the expectations set by the PRA, BoE and FCA. This requires wide-ranging collaboration both within the bank and externally to develop the tools and methodologies needed. As such, we have adopted a unified approach across the Santander UK Group Holdings plc group and therefore present TCFD disclosures on that basis in the Santander UK Group Holdings plc group Annual Report.

(1)Comprises 'Net fee and commission income' and 'Other operating income'.

A more detailed Consolidated Income Statement is contained in the Consolidated Financial Statements.

**2022 compared to 2021**

Profit from continuing operations after tax up 3%.

–Net interest income up 12% up 14bps largely due to the impact of base rate increases.

–Non-interest income down 3%, due to the £71m gain on sale of our UK head office in 2021.

–Operating expenses before credit impairment (charges) / write-backs, provisions and charges down 7% largely due to lower transformation programme spend following significant restructuring in 2021. This programme has embedded lower operational costs and improved the efficiency of the business which should help to mitigate the impact of inflation.

–Credit impairment charges of £320m driven by the deterioration in the economic environment, including higher interest rates, lower GDP, and lower house prices, as well as the risk that higher inflation could impact lending repayments. These charges followed write-backs of £233m in 2021. Loans entering arrears remained low. Arrears stock on mortgages remains low with 0.62% greater than 90 days past due (2021: 0.79%)<sup>(2)</sup>. In Corporate and Commercial Banking, we have seen a small number of single name defaults emerge in Q4-22

–Provisions for other liabilities and charges up 11%, largely related to the £108m penalty for shortcomings in our AML controls between 31 December 2012 and 18 October 2017. We also continued to see a rise in scams with increased fraud charges of £153m in 2022 (2021: £74m). These were partially offset by lower transformation programme charges following significant restructuring in 2021.

Discontinued operations relate to the CIB segment which was moved to SLB under a Part VII banking business transfer scheme, completed on 11 October 2021.

(1) Arrears over 90 days past due: credit cards 0.49% (2021: 0.45%), UPLs 0.61% (2021: 0.51%), overdrafts 2.24% (2021: 2.10%), Consumer Finance 0.44% (2021: 0.36%).

Please refer to the Financial review section of our Annual Report on Form 20-F for the year ended 31 December 2021 for a comparative discussion of 2021 financial results compared to 2020.

Balance sheet review

CUSTOMER BALANCES

This section analyses customer loans and customer deposits at a consolidated level and by business segment. The customer balances below exclude Joint ventures, as they carry low credit risk and therefore have an immaterial ECL, and Other items, mainly accrued interest that we have not yet charged to the customer's account, and cash collateral. A reconciliation between the customer balances below and the total assets as presented in the Consolidated Balance Sheet is set out in the Risk review.

–Other assets and other liabilities decreased, primarily reflecting our approach to liquidity management in 2022.

–Total wholesale funding decreased, with total term funding of £57.8bn (2021: £60.1bn).

–Shareholders' equity decreased, largely due to cash flow hedging of our debt issuance and pension remeasurement.

---

**2022 compared to 2021** 

Capital ratios well above regulatory requirements

–The CET1 capital ratio decreased 70bps to 15.4%. This was largely due to regulatory changes that took effect on 1 January 2022 and a special dividend paid in December 2022. The regulatory changes included the reintroduction of the full CET1 software asset deduction, and implementation of new definition of default regulatory guidance. The impact of increased RWAs and the special dividend were partially offset by post dividend retained earnings. We remain strongly capitalised with significant headroom to minimum requirements and MDA

–Total capital ratio decreased by 150bps to 20.4%, due to lower CET1 capital ratio as outlined above as well as the reduction in Additional Tier 1 and Tier 2 capital securities recognised following the end of the CRR Grandfathering period on 1 January 2022.

–We paid £1.0bn interim dividends, £300m of which was a special dividend (2021: £1.3bn). These were paid following review and approval by the Board in line with our dividend policy.

Chair's report on corporate governance

**Our Board and governance structure**

Maintaining high standards of corporate governance is an essential element to ensure the long-term sustainable success of the Company. In addition to the UK Corporate Governance Code 2018 (the Code) (the standard against which we measure ourselves), we also have internal governance practices and rules, principally:

–The UK Group Framework, which defines clearly our responsibilities and relationship with Banco Santander SA, our ultimate shareholder, taking account of our fiduciary and regulatory responsibilities. This gives us the autonomy to discharge our responsibilities in the UK in line with best practice as an independent board while giving Banco Santander SA the oversight it needs. Clarity of roles and responsibilities is key to ensuring proper accountability for decisions and outcomes.

–The Corporate Governance Framework, which is designed to assist the Board of Directors in discharging their responsibilities and ensuring an appropriate scheme of delegation throughout the Santander UK group.

The Corporate Governance Framework is reviewed regularly by the Board to confirm that governance arrangements remain effective. The corporate governance structure is supported by the internal control and risk management systems. An important principle, applied throughout the Corporate Governance Framework, is that delegation of executive authority is to individual office holders, who may delegate aspects of their authority to others, as appropriate. Executive Committees have been established to support individuals in discharging their responsibilities.

**The role and responsibilities of the Board**

The Board is collectively responsible for promoting the success of Santander UK for the benefit of its stakeholders, taking into account the likely impact of their decisions in the long-term, as well as the interests of our other stakeholders and to its contribution to the wider society.

The Board's schedule and activities are planned to make sure that Directors have regard to the matters necessary to promote the success of the Company, including the broader implications of their decisions for the Company's stakeholders including its shareholder.

The key decisions and matters reserved for the Board's approval, such as the long-term strategy and priorities, are set out in the Corporate Governance Framework. The Board is supported by its Committees which make decisions and recommendations on matters delegated to them under the Corporate Governance Framework. This enables the Board to spend a greater proportion of its time on strategic, forward-looking matters.

**Board Committees**

The Committees play an essential role in supporting the Board, giving focused oversight of key areas and aspects of the business and their

roles and responsibilities are set out in their Terms of Reference which are available at aboutsantander.co.uk and which do not form part of this Annual Report. The Terms of Reference are regularly reviewed by each Committee to make sure they remain appropriate.

Each Committee comprises Non-Executive Directors (NEDs) and a Chair. Except for the Board Nomination and Board Risk Committees which have one Banco Santander Group appointed Non-Executive Director (GNED), all Board Committees are composed of Independent Non-Executive Directors (INEDs) only. Having assessed this in light of the Code recommendations we are satisfied that the Committees will continue to be able to discharge their duties professionally, effectively and efficiently. As the Santander UK Group Holdings plc and Santander UK plc Committees meet substantively simultaneously, they also continue to have the opportunity to benefit from the broader INED group's skills and experience.

The Board and Board Committees of Santander UK plc also met independently from the Board and Board Committees of Santander UK Group Holdings plc twice in 2022.

**Board meetings in 2022** 

There were 11 Board meetings in 2022. Meetings of the Company were held concurrently with Santander UK Group Holdings plc. This model is supported by a number of ring-fencing safeguards to enable the Santander UK plc Board to operate in this way including the appointment of three ring-fenced bank Double Independent NEDs (DINEDs) (one of whom is the senior ring-fencing Director) and a Ring-Fenced Bank Risk Officer.

Regular updates are provided to the Board by the Committee Chairs, CEO, CFO, CRO and myself as Chair. I, as Chair, also held a number of meetings with the NEDs without the Executive Directors (EDs) present. There is a comprehensive and continuous agenda setting and escalation process in place to ensure that the Board has the right information at the right time and in the right format to enable the Directors to make the right decisions. As Chair, I lead the process, assisted by the CEO and Company Secretary, and this ensures that sufficient time is set aside for strategic discussions and business critical items. Together with the Committee Chairs, we ensure Board and Committee meetings are structured to facilitate open discussion, debate and challenge.

The NEDs also receive regular updates from management to give context to current issues.

**How governance contributes to the delivery of our strategy**

Our governance arrangements contribute to the development and delivery of our strategy in various ways, including by taking accountability and responsibility, and ensuring information flows and independent insight from the NEDs.

All Directors are collectively responsible for the success of the Company. The NEDs exercise objective judgement in respect of Board

decisions, and scrutinise and challenge management constructively. They also have responsibilities concerning the integrity of financial information, internal controls and risk management.

The Board is responsible for overseeing and developing our strategy and policies, overseeing risk and corporate governance and monitoring progress towards meeting our objectives and annual plans and monitoring its implementation by the CEO, supported by his wider executive management team. In 2022, the Board regularly reviewed progress against its delivery of the three year business plan. The Board is accountable to our shareholder for the proper conduct of the business and seeks to represent the interests of all stakeholders.

The Board has identified the following key stakeholders: Customers, Employees, Regulators, Communities and Investors.

**Views of the workforce at the Board**

Our colleagues are a key stakeholder, central to the delivery of our strategy, and the Board is committed to ensuring continuous engagement with them. Annemarie Durbin is the designated NED responsible for ensuring that the views of the workforce are made known to the Board. In 2022, as well as extensive reporting on people issues to the Board, Annemarie participated in focus groups, management forums and development workshops. She also had regular meetings with the Head of Culture, Inclusion and Experience to discuss matters such as the employee voice and engagement survey results.

With effect from 1 March 2023, Lisa Fretwell replaced Annemarie Durbin as the designated NED representing the views of the workforce on the Company and Santander UK Group Holdings plc.

**Board activities**

I, together with the CEO and Company Secretary, and supported by the Directors and senior management, make sure that the Board has an appropriate schedule for the year. This is focused on the opportunities to drive growth and profitability of the business, transformation to support the future success of the business, business performance and risk management and customer experience and outcomes. It includes the Company's digital strategy, ensuring the Company is run in a responsible and sustainable way in the interests of its stakeholders, and ensuring that the Company's culture is aligned with its purpose, values and strategy.

The Board ensures regular contact with management and colleagues through a number of means. These include inviting relevant business and function heads to present to the Board or its Committees on latest developments; permitting observers as part of individual senior managers' development plans; scheduling regular meetings for Committee Chairs to meet with relevant senior managers; site visits by one or more NEDs; and topical or technical

Chair's report on corporate governance continued

workshops. Senior leaders are also available to the NEDs for advice and support.

The Board regularly monitors progress against the strategic priorities and performance targets of the business, and in 2022, once again held a separate Board Strategy Day. In advance of the Board Strategy Day, a workshop was held focused on disruption by Fintechs and Neobanks, which was designed to set the scene for the discussions on how and where we want to grow and invest, in the context of an evolving competitive landscape. Presentations at the Board Strategy Day considered the current macro environment, discussing potential changes to the Employee Value Proposition (including the future 'Ways of Working'), before the Board considered and explored opportunities to further grow the business. The day concluded with a presentation by the CEO on potential investments and the financial impact, recognising the trade off between returns and market share/revenue growth.

In 2022, the Board and its Committees received deep dives on a number of areas (e.g. Consumer Duty, Climate Change and ILAAP) and externally facilitated workshops to consider important topics in depth and to engage with key stakeholders. To ensure the most effective use of the time at Board meetings, in addition to the delegation of certain responsibilities to the Board Committees, held informal discussions with Board members. The INEDs also met on several occasions without management and once without me present to assess my performance.

More details of the Board activities in 2022 are set out at the end of this report.

**Culture**

The Board recognises the importance of culture, as a mechanism to support the long-term

sustainable success of the Company. The Board are responsible for setting and overseeing our culture and values as well as monitoring progress on its development. The Board are committed to creating a culture of inclusivity and belonging, as well as creating a healthy culture environment. Throughout the year the Board has received feedback on our culture via a number of mechanisms including engagement with the workforce directly and through the NED chosen to represent the views of the workforce, as well as receiving reports from colleague surveys considering matters including future ways of working and wellbeing. The Board also seeks to ensure that workforce policies and practices are consistent with the Company's values and supports its long-term sustainable success.

**Board responsibilities**

As Chair, I have overall responsibility for the leadership of the Board and for ensuring its effectiveness in all aspects of its operation. These responsibilities are formalised in the Corporate Governance Framework.

The composition of the Board helps to ensure that no one individual or small group of individuals dominates the Board's decision-making. The diversity of skills, experience and background on the Board enables the Board to provide constructive challenge and strategic guidance and to offer specialist advice. There is a clear division of responsibilities between the leadership of the Board and the executive leadership of the business. The responsibilities of the Chair, CEO, SID and NEDs and all Board Committees are agreed by the Board and set out in writing (as part of the Corporate Governance Framework) and are publicly available on our website at www.aboutsantander.co.uk, which does not form part of this Annual Report.

**Board membership**

At 31 December 2022, the Board of Santander UK Group Holdings plc consisted of the Chair (independent on appointment), three INEDs, two EDs and two GNEDs. The Santander UK plc Board, at 31 December 2022, consisted of the Chair (independent on appointment), six INEDs, two EDs and three GNEDs

Biographies of the Directors are set out in the Shareholders information section of this Annual Report. A record of Directors who served in the year is shown in the Directors' Report. The letters of appointment for INEDs and GNEDs are available at the Company's registered office and at the Annual General Meeting.

Through the Board Nomination Committee, we make sure there is the right mix of individuals on the Board, giving an appropriate balance of knowledge, skills, experience and perspectives. Our aim of ensuring orderly succession for Board positions is supported by continuous and proactive processes. We take into account our strategic priorities and the main trends and factors affecting the sustainability and success of the business. We oversee and regularly review the development of a diverse pipeline for succession.

Changes to Board membership are set out in the Directors' report. In 2022, we appointed Mike Regnier as CEO (following Nathan Bostock's departure on 1 April 2022) and Lisa Fretwell as an INED, effective from 1 January 2022. These appointees have valuable skills and experience of financial services, digital, strategy and transformation.

All aspects of diversity form part of our Board succession planning process.

**Board attendance**

The Directors' attendance at the Board meetings held in the year is set out below. Meetings of the Board are generally held concurrently with the Santander UK Group Holdings plc Board, with business specific to each company identified and recorded as appropriate, reflecting the decisions taken by the Board of the relevant entity.

Chair's report on corporate governance continued

**Monitoring independence**

The Board Nomination Committee monitors whether there are relationships or circumstances which may affect a Director's independence, and have concluded that all NEDs are independent in character and judgement. I, as Chair, was independent on appointment when assessed against the circumstances set out in Provision 10 of the Code. No INEDs have a material relationship with the Company nor receive additional remuneration to Directors' fees. In addition, no INEDs serve as Directors of any external companies or affiliates in which any other Director is also a Director.

**Monitoring Director time commitment, interests and fees**

The Board Nomination Committee is responsible for oversight of Conflicts of Interest.

Each Director has a duty under the Companies Act 2006 to avoid a situation in which they have or may have, a direct or indirect interest that conflicts, or may conflict, with the interests of the Company. This duty is in addition to the existing duty Directors owe to the Company to disclose to the Board any interest in a transaction or arrangement under consideration by the Company.

In 2022, the Board Nomination Committee continued to review the time commitment and Directors' potential conflicts of interest to ensure that any such conflicts are managed appropriately and in compliance with CRD IV and ring-fencing requirements. In accordance with Provision 15 of the Code, Directors are required to seek prior approval from the Board before taking up external appointments.

External appointments are disclosed to the Board, before appointment, with an indication of time involved. All directors continue to devote sufficient time to their roles at the Company. No significant external appointments were undertaken by any Directors. The Articles of Association contain provisions that allow the Board to consider and, if it sees fit, authorise situational conflicts.

These powers have operated effectively and the formal system for Directors to declare their interests and for the non-conflicted Directors to authorise situational conflicts continues to be in place. Any authorisations given are recorded by the Company Secretary and Directors are asked to certify, on an annual basis, that the information in the register is correct.

The level of fees paid to INEDs for Board and Board Committee chair and membership were unchanged in 2022, although, following a review, it was decided to pay fees for some of the director responsibilities which had previously not been remunerated. For more, see the Remuneration Implementation Report.

**The right information and support**

The Chair, supported by the Company Secretary, ensures that all Board members receive appropriate and timely information. All Directors have access to the advice of the Company Secretary and the Company provides access, at its expense, to the services of independent professional advisers in order to help the Directors discharge their role. This also applies to Board Committees.

**Board composition**

Ensuring the right balance of skills, experience, independence and knowledge on the Board is the responsibility of the Board Nomination Committee.

**Succession Planning** 

The Board Nomination Committee is responsible for ensuring plans are in place for orderly succession to both Board and senior management positions, and oversees the development of a diverse pipeline for succession.

**Board and Committees' evaluation** 

The annual evaluation, which is typically facilitated externally at least once every three years, highlights areas of further development to enable the Board to continuously improve its performance.

I, as Chair of the Board, with the support of the Board Nomination Committee, lead the Board in considering and responding to the annual review of the Board and Committees' effectiveness, including the performance of individual Directors. In 2022, I asked the Company Secretary to undertake an internally facilitated review of the effectiveness of the Board and Board Committees.

In addition, in 2022, the Board continued to monitor progress against actions for the 2021 externally facilitated review of Board effectiveness.

**Director induction and training** 

The Company Secretary supports the Chair in designing individual inductions for NEDs, which include site visits and cover topics like strategy, balance sheet and capital, key risks and current issues including the legal and regulatory landscape.

Directors who take on new roles or change roles in the year (such as becoming a member of a new Board Committee) attend induction or handover meetings as appropriate. Committee Chairs, with the Committee secretaries, agree Committee specific training, as appropriate. Directors are also given the opportunity to undertake further training so that they are fully comfortable with their role on the Board and to enable them to contribute to the long-term success of the Company.

**Group structure and ring-fencing governance arrangements** 

The substantive business of the Santander UK group continues to be conducted by Santander UK plc, our principal ring-fenced bank (RFB). Ring-fenced banks operate within governance rules defined and overseen by the PRA who have granted Santander UK plc certain ring-fencing governance rule modifications, subject to various safeguards. This allows for certain overlaps of the Board and senior management of Santander UK Group Holdings plc and Santander UK plc, recognising our ownership structure and chosen ring-fencing business model.

At 31 December 2022, the three DINEDs of Santander UK plc were Annemarie Durbin, Mark Lewis and Nicky Morgan. In addition, Annemarie Durbin acts as the SRD of Santander UK plc.

**Appointment and retirement of Directors** 

The Company's Articles of Association require each Director to retire every year at the Annual General Meeting and any Director may offer themselves for re-election by members. For more, see the Directors' report.

Chair's report on corporate governance continued

**Summary of Board Committee activities in 2022**

Our Board Committees conduct their business concurrently with the Santander UK Group Holdings plc Board Committees to ensure alignment of practices, policies and procedures. The following reports detail the governance arrangements, practices and activities of both committees. More information can be found in each of the Committee Chair's Reports in the Santander UK Group Holdings plc 2022 Annual Report.

| Pamela Walkden | 7/7 | 1/2 |

---

Other attendees at Committee meetings in 2022 included the CEO, Chief People Officer, Director, Performance & Reward, and Director, Culture & Capability.

The Committees are responsible for, amongst other things:

–Identifying, nominating and recommending candidates for appointment to the Board.

–Regularly reviewing the structure, size and composition of the Board and its Committees.

–Overseeing the evaluation of Board and Board Committee performance.

–Reviewing corporate and internal governance matters.

**Key activities in the year**

**Succession planning** 

The Committees lead a formal, rigorous and transparent process for the identification, nomination and recommendation of candidates for appointment to the Board and senior management positions.

Part of this process is ensuring that there are succession plans in place for both Board and key management positions encompassing internal and external candidates, and that there is a skills, experiences and diversity matrix which maps each Director's attributes against those which are most relevant for the Board, taking into account the future strategic direction of the Company and its needs. As well as tracking the Board's strengths, this matrix is used to identify gaps in its desired collective skills profile.

While appointments are based on the merit of the individual candidates and objective criteria, we also aim to promote diversity, in its broadest sense, to complement and strengthen the overall Board and its Committees' skills, knowledge and experience. Any appointment also takes account of all legal and regulatory requirements.

In 2022, a significant proportion of the Committees' time was devoted to succession planning, and in particular identifying successors for Chris Jones, Chair of the Audit Committee, and Ed Giera, Senior Independent Director and Chair of the Risk Committee. Both will step down by 2024 after serving as Directors for nine years. To ensure a thorough handover, the Committees were keen to start the selection process early.

Hedley May, an external search consultant with whom the Company and individual Directors have no other relationship, were engaged to assist with the search and selection process. A preferred candidate to succeed Chris Jones as the Board Audit Committees Chair has been identified (subject to regulatory approval) but as the appointment process remains ongoing we will report on it more fully in next year's Annual report, together with details of the induction programme arranged for the new director.

The Committees also reviewed the additional roles that the NEDs take on, such as the Whistleblowers' Champion and Workforce Engagement representative to reallocate some of these when the current incumbents retire. Nicky Morgan was appointed to the new role of Consumer Duty Champion for Santander UK plc.

**Board effectiveness**

Following the detailed and comprehensive external evaluation by Boardroom Review Limited, in 2022 an internal review of the Board and its Committees was conducted by the Company Secretary, assisted by the Head of Internal Governance. Interviews were held with Board members and the Executive Committee members were asked to complete a survey on the Board's performance.

The review concluded that the Board and its Committees continue to operate effectively, with notable improvements now that recently appointed Directors, including the CEO and I, have settled into our roles and established strong relationships with the Banco Santander group. Additional strengths identified were the fostering of an open and transparent atmosphere and the blend of skills and experience on the Board. The review also identified some opportunities for improvement including:

–Oversight of ESG and Responsible Banking - given the increasing importance of these matters, the Board should ensure enough time is allocated to discuss them across the year.

–Agenda planning, Board time and Board materials - there is still room for improvement in these areas and the Chair and Company Secretary will work to enhance the scheduling and operation of Board vs Board Committee meetings.

–Board Committee composition – undertake a review of the Board Committee composition to ensure knowledge is spread among Directors while meeting regulatory requirements.

–Emerging market themes and competitor benchmarking – ensuring the Board remain appraised of market activity.

–Strengthening our alignment with the Banco Santander group – fostered through the attendance of Banco Santander group directors and executives at UK meetings as appropriate, including the Board Strategy Day, and regular Board visits to Madrid.

The Board fully considered the recommendations from the internal evaluation and agreed an action plan which will be regularly reviewed by the Committees in 2023.

In 2022, I also conducted individual Directors' assessments and the SID undertook an assessment of my performance.

**Diversity, inclusion and engagement with stakeholders**

During the year, the Committees considered updates to our Board Diversity and Inclusion Policy. The Board aims to maintain at least two female members and aims to have 40% female representation by 2025, previously having a minimum of 33%, and overall aim of 50% female representation on the Board by 2030. We are also committed to maintaining at least one member from an ethnic minority background. Currently, one of our Directors is from an ethnic minority, and 33% of the Board are female.

Our commitment to the HM Treasury Women in Finance Charter continues, with the aim to create gender balance by setting a target of 50% (+/-10%) women in senior roles (excluding Board members) by the end of 2025. At 31 December 2022, 28% of Executive Committee members were female, 34% of Executive Committee members' direct reports were female and our senior manager female population (mid to senior manager roles) was 33%.

Our representation of Asian, Black and other Minority Ethnic colleagues in senior roles (excluding Board members) increased in 2022, broadly in line with our internal growth target to achieve our ambition of 14% (+/-2%) by 2025.

–Oversee the adequacy of the governance arrangements we have in place.

The Committee undertook a thorough assessment of the Company's emerging and top risks, including financial, operational, and compliance controls. Our top risks and emerging risks are discussed in the Risk Review section of this report. The process for identifying, evaluating, and managing the Company's emerging and top risks is integrated into the overall risk governance framework. Regularly, the Committee reviews and discusses a consolidated enterprise-wide risk report to ensure that they are satisfied with the overall risk profile, risk accountabilities, and mitigating measures.

Other attendees at Committee meetings in 2022 included the Board Chair, CEO, CFO, Chief Internal Auditor, CRO, Financial Controller, Director of Financial Reporting and the external auditor.

The Committee is authorised by the Board to provide oversight of:

–Integrity of the financial statements of the Company and any formal announcements relating to its financial performance, including underlying significant financial reporting judgements and estimates.

–Internal financial control effectiveness.

–The relationship with our external auditors including their independence and objectivity, audit scope and effectiveness of the audit process in respect of their statutory audit of the annual financial statements.

–Internal Audit function effectiveness.

–Recovery and Resolution planning.

–Whistleblowing arrangements.

**Key activities in the year**

**Internal Audit**

–Considered the 2023 Audit Plan and annual report for recommendation to the Board.

–Monitored progress against the 2022 Audit Plan.

**Financial reporting**

**Significant financial reporting issues including judgements and estimates**

The use of assumptions or estimates and the application of management judgement is an essential part of financial reporting. This is considered by the Committee on at least a quarterly basis. The External Auditors also consider these areas as part of their audit of the annual financial statements. More information on the External Auditors' work is set out in their audit report.

In 2022, we focused on the following significant reporting matters in relation to financial accounting and disclosures:

**Credit impairment charges**

–Noted that applying management judgements on IFRS 9 ECL provisioning was difficult given the unusual and unique circumstances due to the cost of living crisis, and the reduction of Covid-related risks.

**Provisions and Contingent Liabilities** 

–Continued to scrutinise the level and adequacy of customer remediation, litigation and other regulatory provisions and challenged the reasonableness of management's assumptions throughout the year.

**Defined benefit pension schemes**

–Reviewed management's approach to illiquid assets valuation where there continues to be inherent uncertainty as their values are based on unobservable market inputs. Reviewed the proposal to continue to use the unaudited flash valuations provided by our private equity advisors, following review of the testing carried out against final audited valuations, and the conclusion that this is management's best estimate of the value.

**Other Areas**

–Reviewed the outcome of management's annual impairment assessments for goodwill and the cost of Santander UK Group Holdings plc's investment in the Company and noted the increase in headroom in the year.

**Oversight of external auditors**

**External Auditors**

PwC were appointed in 2016 and their independence was considered and monitored throughout the year. We were satisfied that PwC continued to meet the independence requirements. Ian Godsmark became lead audit engagement partner from June 2022 following the resignation of Laura Needham from PwC.

Based on a formalised assessment, the Committee satisfied itself as to the rigour and quality of PwC's audit process.

**Non-audit fees**

We have a robust policy on non-audit services provided by our external auditors. Non-audit services were under continuous review throughout 2022 to determine that they were permitted by reference to their nature, assessing potential threats and safeguards to auditor independence as well as the overall ratio of audit to non-audit fees.

All assignments require advance approval, either by the Chair (or in his absence his alternate), under delegated authority for amounts under £250,000 plus VAT or, if larger, by the Committee. This process is in addition to the requirement for all non-audit fees to be approved by the Banco Santander Audit Committee.

Chair's report on corporate governance continued

**Internal Audit**

The Committee has approved the Internal Audit Charter and receives regular updates on the operational effectiveness of the Internal Audit function to confirm that it maintains its independence and to ensure its quality, experience and resourcing is appropriate. This is supplemented by regular interactions between the Chief Internal Auditor and the Committee Chair. We also receive feedback on interactions between Internal Audit, management and our external auditors.

A review is conducted every five years to evaluate the Internal Audit function in respect of its conformance with the standards of the Chartered Institute of Internal Auditors (CIIA), as well as its performance and effectiveness compared to industry peers and good practice. The next review is due in 2023 and a thorough process to select an external provider to carry out the review has been undertaken.

**Whistleblowing**

The Committee oversees Santander UK's whistleblowing arrangements including continuous refinement of our processes to align with evolving best practice. Santander UK recognises the importance of creating an environment where colleagues feel safe and able to Speak Up. Speaking Up is a core behaviour at Santander UK and there are a number of ways colleagues can do this, including raising a concern via Santander UK's Whistleblowing Team.

The Disclosure Committee reports on whether the Annual Report is fair, balanced, and understandable and whether it provides the information necessary for readers to assess Santander UK's position and performance, business model and strategy.

**Effectiveness**

As part of the internally facilitated Board evaluation carried out during the year, the Committee's performance was assessed and it was concluded that the Committee continues to perform effectively.

The Committee is authorised by the Board to

–Set the overarching principles and parameters of remuneration policy across Santander UK. We do so in consultation with the RFB Committee to ensure that the RFB is able to comply with its legal and regulatory obligations, including its ring-fencing obligations.

–Oversee implementation of remuneration policies, including considering and approving the remuneration arrangements (including bonuses) for EDs and senior executives. We approve individual remuneration awards and also changes to senior executive incentive plans.

–Approve the framework by which colleagues are designated as Material Risk Takers (MRT) and oversee MRT remuneration arrangements, including bonuses.

Details of the structure of our remuneration arrangements and the activities of the Remuneration Committee in the year are provided in the Remuneration Committee Chair's Report, Remuneration Policy and Implementation Reports.

Remuneration policy report <br>

**Basis of preparation**

This report has been prepared on behalf of the Board by the Board Remuneration Committee. We comply with the statutory reporting obligations for large private companies. Furthermore, we applied the UK Corporate Governance Code 2018 (the Code) and complied with the Provisions other than where stated in the Directors' Report. In addition, we comply with other listed disclosure requirements to the extent considered appropriate taking into account our ownership structure.

Accordingly, several voluntary disclosures relating to remuneration are presented in this report.

**Remuneration policy for Executive Directors (EDs)** 

Our remuneration policy, which applies to EDs, is outlined below. Remuneration is structured in two elements: fixed and variable pay. Fixed pay is set at market competitive levels appropriate for the role. Variable pay rewards the delivery of internal financial targets, key strategic priorities and individual performance, subject to risk adjustment.

**Remuneration policy applicable to Executive Directors in the year**

|:---|:---|:---|
| Fixed pay | Principle and description | Policy |
| **Base salary** | –To attract and retain EDs of sufficient calibre and with the skills to deliver our strategy, taking into account the demands and complexity of the role. | &nbsp;&nbsp;&nbsp;–Base salaries are normally reviewed annually. In reviewing base salaries the Committee considers a number of factors, including:<br>–the skills required and responsibilities of the role alongside the market value of those attributes;<br>–the requirement for base salaries to be set at a level to avoid inappropriate risk taking;<br>–base salary increases across the colleague population; and<br>–prevailing market and economic conditions. |
| **Pension arrangements** | –To provide a discrete element of the package to contribute towards retirement. | &nbsp;&nbsp;&nbsp;–All EDs receive a cash allowance in lieu of pension in line with the wider workforce average, currently 9% of salary. |
| **Other benefits** | –To offer a competitive package and to support employee wellbeing. | –Including but not limited to: private medical insurance for EDs and their dependants, life assurance, health screening, and relocation allowances where relevant.<br>–Access to Santander UK's all-employee share schemes on the same terms as all UK employees. |

In addition, the CEO is subject to a Shareholding Policy, which ensures alignment with the long-term interests of Banco Santander shareholders. The requirement under the policy is set at two times the incumbent's net salary upon appointment. A formal post-employment shareholding requirement is therefore not in place.  |

Remuneration policy report continued <br>

Our remuneration policy continues to meet regulatory requirements. Santander UK applies a 2:1 variable to fixed pay cap in line with approvals granted to Banco Santander SA by its shareholders. For control function roles, a lower ratio of 1:1 is normally applied.

**Executive remuneration policies**

**and principles**

Our core values of Simple, Personal and Fair drive our remuneration policy. We focus on delivering a reward framework that is easily understood, tailored to individual roles, competitive and fair.

**The key drivers of our Remuneration Policy**

**Alignment to culture**

–To design policies aligned to the long-term success of the business, which support the delivery of our strategy and reinforce our values.

–To base variable pay on a balanced scorecard of quantitative and qualitative metrics which reflect our strategic priorities across Customers, Shareholders, People and Communities. This ensures that our day-to-day activities align with Santander UK's strategic priorities which focus on customer loyalty and experience, simplification, improved efficiency and sustainable growth while aiming to be the best bank for all our stakeholders.

**Simplicity**

–To ensure our approach to remuneration is transparent and easily understood.

–To operate clear structures to support each colleague to link their contribution to the success of the organisation.

**Risk**

–To apply a consistent approach to reward for all our employees which upholds our prudent approach to Risk Appetite set as part of a Santander UK-wide framework. Risk adjustment occurs at an individual and bonus pool level.

–To provide a package that is balanced between fixed and variable pay, and short-term and long-term horizons, which aligns to our strategy whilst promoting prudent risk management.

–To ensure remuneration is compliant with applicable regulations and legislation.

**Fairness**

–To take into account an assessment of the EDs' performance against objectives set at the start of the year covering a range of financial, non-financial, quantitative and qualitative criteria.

–To set robust and stretching internal targets and reward exceptional performance.

–To attract, retain and motivate employees of the highest calibre by providing total remuneration which reflects individual and Company performance, is competitive, reflects the responsibilities of the role and drives the organisation's growth and transformation.

–To consider wider employee pay and conditions when determining pay of our Executives.

**Clarity**

–The Committee reviews remuneration reporting on an annual basis against principles of best practice and developments in corporate governance, including the Code. Our reporting is designed to be transparent to promote effective stakeholder engagement, whilst reflective of our structure.

**Predictability**

–The Committee annually reviews the variable pay opportunity for individuals and the basis of the bonus pool calculation. Due to commercial sensitivity, these are not disclosed as per the provisions of the Code. Directors' remuneration is within the variable pay cap as approved by Banco Santander SA shareholders and set out above.

**On recruitment**

When appointing a new ED, base salary is set at a market competitive level appropriate for the role, taking into consideration a range of factors including role scope and responsibilities, internal and external peer groups, relevant experience, and affordability.

Unless determined otherwise, any new ED will receive a pension allowance in line with the wider workforce average, currently 9% of salary. Benefits available will typically be aligned to the wider employee population.

Remuneration will be established in line with the Remuneration Policy, as set out in the EDs' remuneration structure table in this report.

Relocation support and international mobility benefits may also be given. Where provided, relocation assistance will normally be a capped amount for a limited time. In cases of international mobility, the Committee will have discretion to offer benefits and pension provisions which reflect home country market practice and align to relevant legislation.

**Buy-out awards**

Compensation may be provided to EDs recruited externally for the forfeiture of any awards on leaving their previous employer. The Committee retains discretion to make such compensation as deemed appropriate to secure the relevant individual's employment and will ensure any such payments align with both the long-term interests of Santander UK and the prevailing regulatory framework.

Such payments will be in line with the awards foregone as a result of leaving the previous employer taking into account value, form of awards, vesting dates and the extent to which performance conditions applied to the original awards.

**Service agreements**

The key terms and conditions of employment are set out in individual service agreements. These agreements include a notice period of six months from both the ED and the Company.

The agreement reserves a right for the Company to terminate employment immediately with a payment in lieu equal to the ED's fixed pay for the notice period. In the event of termination for gross misconduct, neither notice nor payment in lieu of notice is required.

Remuneration policy report continued <br>

**Termination payments**

The remuneration impact of an ED leaving the Company, including treatment of variable pay and/or any termination payment will reflect the terms of the service agreements, relevant scheme rules, regulatory requirements and the Committee's policy relevant to the reason for leaving.

Outstanding variable pay awards will generally lapse on termination, other than where an individual is considered a 'good leaver'. Where an ED is a good leaver, eligibility to variable pay awards will normally subsist until the relevant scheduled payment dates and will remain subject to performance where relevant.

The Committee determines whether an ED is a good leaver. Usual good leaver circumstances include but are not limited to: injury, ill-health, disability, redundancy, retirement and death. The Committee may, at its discretion, determine an ED a good leaver in any other circumstances.

A framework is in place to guide the Committee to determine the discretionary circumstances when good leaver status is appropriate. Other than a payment in the event of redundancy, there are generally no other payments upon termination of employment for EDs.

In the event of a change in control, any outstanding variable pay awards will be treated in line with the relevant scheme rules, taking into account applicable regulatory requirements.

**Risk and Performance adjustment**

We continue to meet the regulatory requirements in respect of risk and performance adjustment. All variable remuneration is subject to adjustment for current and future risks through our Additional Risk Adjustment Standard which is linked to our Board approved Risk Appetite.

The Standard provides both a formula-based assessment against Santander UK's Risk Appetite and an additional qualitative risk event assessment that can reduce the bonus pool or individual awards to nil at the Committee's discretion.

Our Individual Remuneration Adjustment Standard provides a framework for the process, governance and standards relevant for decisions in relation to individual performance adjustments following an incident, including the application of malus and clawback.

Performance adjustments may include, but are not limited to:

–reducing an award for the current year;

–reducing the amount of any unvested deferred variable remuneration;

–requiring an award which has not yet been paid to be forfeited; and

–requiring repayment on demand (on a net basis) of any cash and share awards received at any time for a period of up to ten years following the date of award.

The Committee has full discretion to prevent vesting of all or part of an amount of deferred remuneration and/or to freeze an award during an ongoing investigation in a number of circumstances, including:

–colleague misbehaviour, misconduct or material error;

–material downturn in the performance of Santander UK or a relevant business unit; and

–Santander UK or a relevant business unit suffering a material failure of risk management.

When determining variable pay awards for individuals performing roles across Santander UK plc and Santander UK Group Holdings plc, the Santander UK Group Holdings plc Board Remuneration Committee will apply any necessary discretion based on factors related to UK group entities outside of Santander UK plc. This discretion is subject to validation by the Santander UK plc Board Remuneration Committee.

The Committee seeks input from the Chair of the Board, Chair of the Board Risk Committee, Chair of the Board Audit Committee, Chief Risk Officer, Director of Compliance, Chief People Officer and Chief Internal Auditor when determining whether any performance or risk adjustments are required.

**Policy for all employees**

Our performance and reward approach across the Company supports our business strategy, rewards strong performance and reinforces our values within the approved risk management framework. The general principles of the Remuneration Policy broadly apply across all colleagues where appropriate, and are designed to facilitate recruitment, motivation and retention whilst driving performance.

The composition of remuneration packages for EDs is aligned with the broader colleague population, comprising salary, benefits, workforce aligned pension provisions and eligibility for discretionary variable pay dependent on role and responsibility.

The Committee annually approves the operation of variable reward schemes for all our colleagues to ensure they reward appropriate behaviour and do not incentivise activities which are outside risk appetite.

Remuneration implementation report <br>

**Introduction**

This section of the report outlines how our Remuneration Policy was implemented for 2022.

**Variable Pay Plan**

To incentivise and reward EDs for achieving superior and sustained performance, our Directors participate in an annual variable incentive plan. A balance of financial and non-financial performance metrics are selected annually by the Committee and are aligned with our strategy as measured over the financial year. Multi-year deferral and delivery in Banco Santander SA shares ensure that EDs' interests are aligned to the long-term interests of the business. Further long-term performance testing also applies for the CEO.

Both upfront and deferred awards are made at least half in shares or share-linked instruments. The deferred element is delivered over seven years. Effective 2022 and for the CEO only, the first three deferred tranches of awards are subject to further performance testing against long-term metrics. Awards delivered in shares or share-linked instruments are subject to an additional one-year retention period from the point of delivery.

The 2022 Variable Pay Plan pool was determined based on a range of metrics using a balanced scorecard approach as follows:

**Quantitative assessment**

A quantitative assessment is undertaken against a balanced scorecard of financial and non-financial metrics that are key to Santander UK's 2022 strategy. Performance metrics are reviewed annually to ensure continued alignment with strategy and, for 2022 a simplified scorecard comprised:

–Customers (Net Promoter Score, Loyal Customers and Total Customers)

–Shareholders

–ROTE

–RORWA (where an accelerator could apply subject to ROTE and Capital generation)

–Sustainability (Financial Empowerment)

–People (Employee Engagement and a Diversity and Inclusion multiplier).

A profit underpin applies which requires Profit after Tax to remain positive in order to pay any award, with a reduced pool should profit reduce substantially from the prior year.

**Qualitative assessment**

A qualitative assessment adds context to the quantitative assessment and ensures a balanced view of performance is taken. Performance is assessed across metrics including but not limited to: customers (conduct risk), profitability (results and costs) and responsible banking.

**Banco Santander Group Multiplier**

The Committee has the discretion to adjust the pool upwards or downwards to reflect overall Banco Santander performance if appropriate.

**Regional Adjustment**

A Regional Adjustment was introduced in 2021, to reflect the UK's contribution to performance of the Banco Santander group's European Region (comprising Spain, Portugal, Poland and the UK).

**Exceptional Adjustment**

Exceptional adjustments allow for unexpected factors or additional internal targets not covered by the quantitative or qualitative assessments to be reflected in variable pay outcomes.

**UK-focused risk adjustment**

The UK-focused risk adjustment is linked to Santander UK's Risk Appetite and provides both a formula-based assessment against Risk Appetite and an additional qualitative risk event assessment overlay. Consideration is given to risk appetite limit breaches including but not limited to: customers, conduct, operational, reputational and financial crime risk. This can result in a downward risk adjustment of up to 100% of the bonus pool or individual awards at the discretion of the Committee.

The Committee reviews and approves remuneration governance and frameworks on an annual basis to ensure continued compliance with the relevant regulatory rules, including for ring-fencing.

**Individual assessment**

The allocation of the pool is based on an individual's performance, taking into account a range of factors. Specifically an individual's performance is assessed 50% against the delivery of priorities (the 'What'), 40% against the behaviours exhibited to deliver these priorities (the 'How') and 10% on Risk.

**Deferred long-term awards**

Effective 2022, performance testing applies to a portion of the deferred awards for the CEO. Prior to 2022, this applied to all EDs. Any outstanding deferred awards granted to EDs prior to 2022 will remain subject to performance testing.

Performance testing applies to the first three deferred tranches of the 2022 awards (36% of the total award) which are payable in 2026, 2027 and 2028. Performance is measured over a three-year period 2023 to 2025.

The performance measures for 2022 awards are relative TSR, ROTE and ESG metrics. Following the performance assessment, the level of awards will be adjusted accordingly.

To drive performance, these measures can now both reduce and increase the overall value of the deferred awards.

**Transformation Incentive Plan**

This is a one-off long-term incentive plan which is designed to recognise the achievement of financial targets and an enhanced customer experience, whilst maintaining appropriate conduct controls and risk management, over the course of our transformation period.

Awards under the plan will be assessed over the period 1 January 2021 to 31 December 2023. Awards are granted half in cash and half in share-based units (linked to the Banco Santander SA share price), and will vest in accordance with regulatory requirements.

Remuneration implementation report continued <br>

**2022 Business Performance and Impact**

**on Remuneration**

In the context of continued economic uncertainty and high inflation, our priority remains supporting our customers and people. Despite this challenging operating environment, the hard work of our colleagues has helped us to deliver a strong set of results. Strong profit performance was driven by net mortgage lending. Both our customer deposits and customer loans grew as part of our prudent balance sheet management. We retained our 14 million customers throughout the year and for the first time the number of digital customers accounts for half our customer base.

Our ongoing transformation programme has realised considerable savings which has helped mitigate the impact of rising inflation whilst allowing us to continue to improve our customer experience and deliver against our strategic priorities of being a responsible and sustainable business.

Whilst the Committee acknowledged this strong performance, it also recognised the seriousness of the penalty imposed by the FCA in December 2022 relating to historical anti-money laundering controls between 2012 and 2017 and the importance of reflecting this, alongside other factors, in determining variable pay awards. The failings and penalty were therefore taken into account as part of the quantitative and qualitative steps in the 2022 bonus pool determination, with a further discretionary adjustment applied.

**Context for decision making**

The Committee ensures that broader remuneration policies and practices for employees across the Santander UK group are taken into account when setting policy for executive remuneration. The Committee reviews remuneration trends across the Santander UK group including the outcome of any pay negotiations with our recognised trade unions and considers the relationship between executive remuneration and that of other Santander UK group employees, as well as remuneration in the wider UK market when making decisions on executive pay.

A particular focus of the Committee during the year has been the impact of the cost of living crisis on our colleagues. Several management initiatives designed to support our people, particularly the lowest paid, were endorsed by the Committee during the year. In addition, a review of all cost of living initiatives was undertaken at year end to ensure that the approach taken was both fair and effective. The cost of living crisis was considered carefully by the Committee when determining EDs' 2022 variable pay awards and remuneration for 2023.

The Committee oversees broader workforce remuneration policies and practices, the implementation of remuneration and related employment policies across Santander UK and the salary and variable pay awards for all Material Risk Takers. It also approves the design of any material performance-related pay plans.

As part of the monitoring of pay, the following is considered:

–Santander UK's engagement with its recognised trade unions on pay and benefits matters for all colleagues;

–Annual pay reviews for the general employee population;

–Santander UK group-wide pension and other benefit provisions;

–The design of and overall spend on variable incentive arrangements; and

–An assessment of conduct across the business.

The Committee is focused on ensuring that colleagues are not subject to undue pressures or inappropriately incentivised. This is monitored using existing employee engagement indicators including engagement surveys.

The Committee always considers the broader stakeholder environment when setting policy or reaching decisions on executive pay.

**Summary of remuneration arrangements for the Chief Executive Officers**

Nathan Bostock stepped down as CEO effective 1 April 2022 to take up a position within Banco Santander. As such, he retains the right to deferred variable pay awards and was eligible for a pro-rated bonus to reflect time served in 2022. During the year, Santander UK welcomed Mike Regnier who was appointed CEO on 1 April 2022. Details of Mike's remuneration are disclosed in the Executive Directors' remuneration table below.

(1) Taxable benefits for the Executive Directors comprise a range of benefits including, but not limited to, private health care, life cover and car benefit. Included in the 2021 and 2022 figures for Duke Dayal is a relocation allowance of £500,000 p.a..

(2) The 2021 Variable Pay Plan awards made to Nathan Bostock and Duke Dayal have been restated to account for 36% of the awards being subject to long-term metrics. Performance against these metrics can decrease the award to 0% and may not increase the award value. Previously the value of the Variable Pay Plan awards have been disclosed in full which has resulted in an overstatement post the application of performance conditions. The value of the 2021 Variable Pay Plan subject to long-term performance conditions (currently Nathan Bostock: £1,048,680 and Duke Dayal: £715,748) will be disclosed at the close of the performance period. Effective 2022, 36% of the CEO's 2022 Variable Pay Plan award will be subject to long-term performance metrics assessed over three years. No other executive, aside from the CEO, will be subject to long-term performance metrics. Performance against these metrics can increase the value of this element by up to 25% of original value, or decrease the award to 0%. The value of both the current and former CEOs' 2022 Variable Pay Plan awards not subject to performance conditions, i.e. 64%, are disclosed above. The value subject to further performance conditions (currently Mike Regnier: £640,588 and Nathan Bostock: £223,864) will be disclosed at the close of the performance period upon vesting.

(3) Mike Regnier was appointed as CEO on 1 April 2022. Upon appointment, Mike Regnier was awarded guaranteed variable remuneration of £660,648 to compensate for remuneration forgone from his previous employer. This has not been included in the Total Remuneration value above.

(4) Nathan Bostock stepped down as CEO on 1 April 2022. The figures above reflect remuneration received whilst serving as a Board Director. No further payments are due.

(5) An additional one-off award was delivered to Duke Dayal in recognition of his contribution to regulatory projects during his service with Santander Holdings USA prior to joining the Company, and subject to Santander UK plc corporate and individual performance conditions during 2021. The value of the award is £294,532, and is included in the bonus value for 2021.

(6) Tony Prestedge was appointed as an Executive Director on 16 December 2020 and stepped down on 28 July 2021. In 2022, Tony Prestedge received payments in lieu of notice totalling £172,856. No further payments are due.

Remuneration implementation report continued <br>

**Stakeholder views**

During 2022, Santander UK continued to engage with key stakeholders on remuneration related matters including its main regulators, the PRA and FCA.

Regular engagement takes place with our shareholder to ensure there is alignment with remuneration constructs across the wider Banco Santander group while meeting all regulatory requirements and expectations. The outcome of these discussions drives our bonus pool construct.

In addition to her role as RFB Committee Chair, Annemarie Durbin performs the designated NED role, with responsibility to further enhance the employee voice in the boardroom on matters associated with organisational culture. This is set out in further detail in the Chair's report on Corporate Governance.

Frequent colleague pulse surveys were conducted throughout 2022. This 'Your Say' function has enabled colleagues to share thoughts and ideas more frequently and anonymously all year round. Alongside other virtual listening forums, this gives a more frequent gauge of employee sentiment.

Additionally, discussions are conducted with union representatives during the annual pay review cycle and on relevant employee reward matters on a more frequent basis.

**CEO pay ratio**

Santander UK is committed to delivering fair pay which attracts, retains and motivates colleagues of the highest calibre across all grades. In line with this commitment, the Committee has oversight of compensation across the organisation, including pay ratios, and considers this when determining reward outcomes. We continue to voluntarily disclose the ratio of the CEO's total remuneration to that of colleagues.

The CEO's pay mix is weighted more heavily towards variable pay to incentivise the achievement of stretching internal targets and long-term value creation. This can lead to greater variability in total remuneration. In contrast, the typical pay mix of our less senior colleagues places more emphasis on fixed pay, to ensure earnings offer security and certainty, and to meet our commitment to colleague financial wellbeing.

Changes in the ratio are therefore influenced by the differences in remuneration structure, rather than an increase in pay disparity. The ratio has decreased from 96:1 (re-stated and explained in footnote 4 below) in 2021 to 84:1 in 2022. The reduction in pay ratio is attributable to a number of different factors. These include an increase in average total remuneration amongst the employee population, and a reduction in the CEO remuneration package year-to-year. In assessing the pay ratio, the Committee is confident that the Company's policy on remuneration is fair and consistent with our all-employee pay policies.

**Advice and support provided to the**

**Committee**

As permitted by its Terms of Reference, the Committee has engaged the advice and support of Deloitte LLP (Deloitte) as independent remuneration consultants at the expense of the Company. Total fees (excluding VAT) for advice and support provided to the Committee in 2022 were £176,600 (2021: £199,050). Deloitte was first appointed as Adviser to the Committee following a formal tender process conducted in 2015. Following a further tender process in 2022, Deloitte was reappointed as the Committees' advisor. Deloitte's independence and effectiveness will continue to be reviewed annually. Deloitte is a founding member of the Remuneration Consultants Group and voluntarily operates under the Code of Conduct in relation to executive remuneration consulting in the UK.

The Committee is satisfied that the Deloitte engagement partner and team that provides remuneration advice to the Committee do not have connections with Santander UK that may impair their independence, following review in 2022.

In 2022, Deloitte also provided unrelated tax, advisory, risk, assurance and consulting services to Santander UK.

By Committee invitation, the Chair, CEO and designated representatives from business functions attend meetings as appropriate to advise on HR, Risk, Legal and Regulatory matters in support of the Committee's work. Attendees included the Chief People Officer, Performance & Reward Director, CRO and Company Secretary.

---

(1) Employee pay is calculated based on the 'Option A' methodology. We have chosen Option A as it gives the most reliable and accurate result by calculating a comparable single figure for each employee.

(2) Employee pay data is based on full time equivalent pay for Santander UK plc employees. This excludes a small number of employees in the rest of the Santander UK group. Including those employees results in a ratio consistent with the above. For each employee, total remuneration is calculated based on fixed pay accrued in the 2022 financial year, and variable pay is either based on actual bonuses in respect of the 2022 year (where these are available) or modelled target bonuses where actuals are not yet available.

(3) The CEO's total remuneration is aligned to that disclosed in the Executive Directors' remuneration table on the previous page.

(4) The 2021 ratios are re-stated above. These were originally calculated based on fixed pay accrued within the 2021 year, in addition to target bonuses for eligible colleagues. The 2021 ratios have now been recalculated using 2021 fixed pay and bonuses paid in 2022 in respect of 2021 for all employees. The CEO's 2021 total remuneration has been restated to account for a component of that award being subject to long-term metrics, in line with the approach to the Executive Directors' remuneration table.

(5) The values used for the current and former CEOs' 2022 Variable Pay Plan awards are the same as those stated in the Executive Directors' remuneration table i.e. the component which is not subject to performance conditions is used for the CEO pay ratio calculation above. The calculation also excludes the award of guaranteed variable remuneration of £660,648 made to Mike Regnier upon joining, to compensate for remuneration foregone from his previous employer.

Directors' report <br>

**Introduction**

The Directors submit their report together with the financial statements for the year ended 31 December 2022. The information in the Directors' Report is unaudited, except where indicated.

**Corporate structure, Subsidiaries and Branches**

Santander UK plc is a subsidiary of Banco Santander SA, a Spanish retail and commercial bank with a market share in ten core countries in Europe and the Americas.

Santander UK was formed from two former building societies, Abbey National and Alliance & Leicester, together with the branch network and savings business of Bradford & Bingley, and has operated under a single brand since 2010.

Santander UK plc is a wholly-owned subsidiary of Banco Santander SA and all of its ordinary shares are unlisted and held by Santander UK Group Holdings plc, which is a wholly owned subsidiary of Banco Santander SA.

The Company's preference shares are listed on the London Stock Exchange and both the Company and Santander UK Group Holdings plc have other equity instruments in the form of AT1 securities listed on various securities exchange markets, including the London Stock Exchange and Euronext Dublin.

In addition, the Company and Santander UK Group Holdings plc are subject to US Securities Exchange Act reporting requirements as they have debt securities registered in the United States.

The Santander UK group consists of a parent company, Santander UK plc, incorporated in England and Wales, and a number of directly and indirectly held subsidiaries and associates. The Company directly or indirectly holds 100% of the issued ordinary share capital of its principal subsidiaries. All companies operate principally in their country of incorporation or registration.

As a result of ring-fencing implementation in 2018, and requirements set out in the Financial Services (Banking Reform) Act 2013, Santander UK plc and its subsidiaries comprise of only entities whose business is permitted under the Act as a ring-fenced bank. For more information, see Note 19.

**Results and dividends**

For details of the results for the year, see the Income Statement in the Consolidated Financial Statements. For more on dividends, see Note 10.

Details of Santander UK's activities and business performance in 2022, together with an indication of the outlook, are set out in the Strategic report and the Financial review.

**Events after the balance sheet date**

There have been no material post balance sheet events, except as set out in Note 43.

**Directors**

Biographies of the Directors are included in the Shareholder information section. Details of their emoluments and interests in shares are outlined in the Directors' Remuneration Implementation report. For more on changes to the composition of the Board, see the Chair's report on Corporate Governance.

**Appointment and retirement of Directors**

All Directors are appointed and retire in accordance with the Company's Articles of Association, the UK Companies Act 2006 and the UK Group Framework. The Directors are required to retire every year at the Annual General meeting and may offer themselves for re-election.

Lisa Fretwell was appointed to the Board on 1 January 2022 as an INED and Mike Regnier joined the Board on 1 April 2022, as an Executive Director and CEO. Nathan Bostock resigned as an Executive Director and CEO on 1 April 2022.

**Directors' indemnities**

Directors' and Officers' liability insurance cover was in place throughout the year, in addition to a deed of indemnity to provide cover to the Directors for liabilities to the maximum extent permitted by law. These remain in force for the duration of the Directors' period of office from the date of appointment until such time as any limitation periods for bringing claims against the Directors have expired. The Directors, including former Directors who resigned in the year, benefit from these deeds of indemnity which constitute qualifying third party indemnity provisions for the purposes of the Companies Act 2006. Deeds for existing Directors are available for inspection at the Company's registered office.

The Company has also granted an indemnity which constitutes 'qualifying third party indemnity provisions' to the Directors of its subsidiary and affiliated companies, including former Directors who resigned in the year and since the year-end. Qualifying pension scheme indemnities were also granted to the Trustees of the Santander UK group's pension schemes.

**Employees**

We continue to ensure that Santander UK's remuneration policies are consistent with its strategic objectives and are designed with its long-term success in mind.

**Communication**

Santander UK aims to involve and inform employees on matters that affect them. The intranet is a focal point for communications and the 'AskHR' website connects employees to all the information they need about working for Santander UK. We also use face-to-face communication, such as team meetings and roadshows for updates.

Santander UK regularly considers employees' opinions and asks for their views on a range of issues through regular engagement and surveys. For more information, on colleague engagement and initiatives, see the Strategic Report.

**Employee Designated Non-Executive Director**

Annemarie Durbin is the Santander UK Employee Designated NED representing the views of employees in the Boardroom.

**Consultation with Employees**

Santander UK has a successful history of working in partnership with its recognised trade unions, Advance and the Communication Workers Union (CWU), who collectively negotiate on behalf of approximately 99.5% of our UK workforce. Both trade unions are affiliated to the Trades Union Congress. We consult Advance and the CWU on significant proposals including those relating to change across the business at both national and local levels.

**Employee share ownership**

Santander UK continues to operate two all-employee, HMRC approved share schemes: a Save-As-You-Earn (Sharesave) Scheme and a Share Incentive Plan (SIP). Those employees who are designated as Material Risk Takers receive part of their annual bonus awards in Banco Santander SA shares/share linked instruments. Details of the plans and the related costs and obligations can be found in the Share-based payments and compensation sections in Notes 1 and 36.

**Disability**

Santander UK is committed to equality of employment, access and quality of service for disabled people and complies with the UK Equality Act 2010 throughout its business operations. Santander UK has processes in place to help train, develop, retain and promote employees with disabilities. We are a Disability Confident Employer achieving the 'Leader' level. We are committed to giving full and fair consideration to employment applications by disabled people, having regard to their particular aptitudes and abilities, and for continuing the employment of employees who have become disabled by arranging appropriate training and making reasonable adjustment in the workplace.

Directors' report continued <br>

**Share capital**

Details about the structure of the Company's capital can be found in Note 32.

For details of employee share schemes and how rights are exercisable, see Note 36.

The powers of the Directors in relation to share capital are set out in the Company's Articles of Association. These are available for inspection on request.

**Financial instruments**

The financial risk management objectives and policies of Santander UK and the policy for hedging, along with details of Santander UK's exposure to credit risk, market risk and liquidity risk are set out in the Risk review.

**Research and development**

Santander UK has a comprehensive product approval process and policy. New products, campaigns and business initiatives are reviewed by Santander UK's Proposition Approval Forum.

**Supervision and regulation**

The Company is authorised by the PRA and regulated by the FCA and the PRA (dual regulated). Some of its subsidiaries and joint venture companies are also authorised by the FCA and the PRA (dual regulated) or the PRA or the FCA (solo regulated).

While Santander UK operates primarily in the UK, it is also subject to the laws and regulations of other jurisdictions in which it operates or has listed debt securities such as the US.

**Internal controls**

**Risk management and internal controls** 

The Board and its Committees are responsible for reviewing and ensuring the effectiveness of management's system of risk management and internal controls.

We have carried out a robust assessment of the principal and emerging risks facing Santander UK including those that would threaten its business model, future performance, solvency or liquidity. Details of our principal risks, our procedures to identify emerging risks, and how these are being managed or mitigated are set out in the Risk review. A summary of our Top and Emerging Risks is also set out in the Strategic report.

**Management's report on internal control over financial reporting**

Internal control over financial reporting is a component of an overall system of internal control. Santander UK's internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with UK-adopted international accounting standards (IAS) and International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). Santander UK's internal control over financial reporting includes:

–Policies and procedures that pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of assets.

–Controls providing reasonable assurance that transactions are recorded as necessary to permit the preparation of financial statements in accordance with UK-adopted IAS and IFRS, and that receipts and expenditures are being made only in accordance with authorisations of management.

–Controls providing reasonable assurance regarding prevention or timely detection of unauthorised acquisition, use or disposition of assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or because the degree of compliance with policies or procedures may deteriorate.

Management is responsible for establishing and maintaining adequate internal control over the financial reporting of Santander UK. Management assessed the effectiveness of Santander UK's internal control over financial reporting at 31 December 2022 based on the criteria established in the Internal Control – Integrated Framework issued by the Committee of Sponsoring Organisations of the Treadway Commission (COSO) in May 2013.

As a registrant under the US Securities Exchange Act of 1934, Santander UK's management is responsible for establishing and maintaining an adequate system of internal control over financial reporting in order to ensure the accuracy and reliability of Santander UK's Financial Statements and the Form 20-F submitted to the SEC.

In line with COSO and SEC requirements, controls recognised as Sarbanes-Oxley applicable are subject to annual testing and certification by management including an attestation by the CEO and the CFO that they are operating effectively and that the internal control over financial reporting can be relied on.

All Sarbanes-Oxley control weaknesses identified are captured, assessed and included in the year-end assessment of the reliability of the Internal Control environment. They are reported on an ongoing basis to the Board Audit Committee to ensure the control environment is continuously improved.

Based on this assessment, management concluded, at 31 December 2022, that Santander UK's internal control over financial reporting was effective.

**Disclosure controls and procedures over financial reporting**

Santander UK's management has evaluated, with the participation of its CEO and CFO, the effectiveness of its disclosure controls at 31 December 2022. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error, and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

Based upon this evaluation, the CEO and the CFO have concluded that, at 31 December 2022 , Santander UK's disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by Santander UK in the reports that it files and submits under the US Securities Exchange Act of 1934 is recorded, processed, summarised and reported within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to Santander UK's management, including the CEO and CFO, as appropriate, to allow timely decisions regarding disclosure.

**Statements of Compliance**

**The UK Corporate Governance Code 2018 (the Code)** 

Santander UK complies with the Code wherever applicable in order to achieve the best standards of corporate governance. The Code applied to the financial year ended 31 December 2022 and the Board confirms that it applied the principles and complied with those provisions of the Code throughout the year, except as follows:

–Provision 17: The Company does not comply with the requirement for the Board Nomination Committee (BNC) membership to comprise a majority of INEDs, following the appointment of Pamela Walkden, as a GNED in October 2021. Whilst Pamela Walkden is not an INED, her credentials and experience were felt to be invaluable to the BNC. We have assessed the implications and believe that the approach we follow is appropriate for our size and ownership structure.

–Provision 25: The Board Risk Committee (BRC), since the appointment of Pamela Walkden as a GNED in October 2021, has not been composed of only INEDs. We have assessed the implications and believe that the approach we follow is appropriate for our size and ownership structure, recognising the experience and expertise that the GNED brings to BRC.

–Provision 36: The Board Remuneration Committee has not developed a policy for post-employment shareholding requirements. However, the structure of variable pay for EDs and other senior executives ensures that they acquire a meaningful shareholding in Banco Santander SA which is held over a period of up to eight years and which extends for a significant period post employment. For details, see the Remuneration Policy Report.

Directors' report continued <br>

–Provisions 40 and 41: Due to commercial sensitivity, we have opted not to provide all of the disclosures required by Provision 41. The details not provided relate to (1) the extent to which discretion has been applied to remuneration outcomes and the reasons why and (2) a description, with examples, of how the Board Remuneration Committee has addressed the factors in Provision 40 (specifically predictability as we do not provide the range of possible values of rewards to individual directors). Specific engagement does not take place with the workforce to explain how executive remuneration aligns with wider company pay policy. However, an explanation is available for employees in the Directors' Remuneration Report. Details of the structure of our remuneration arrangements and key considerations of the Committee in the year are included in the Board Remuneration Policy and Implementation Reports.

**UK Finance Disclosure Code for Financial Reporting**

Santander UK's financial statements for the year ended 31 December 2022 have been prepared in compliance with the principles of the UK Finance Disclosure Code for Financial Reporting.

**Going concern**

The going concern of Santander UK is reliant on preserving a sufficient level of capital and adequately funding the balance sheet. In making their going concern assessment in connection with preparing the financial statements, the Directors considered a wide range of information including Santander UK's business and strategic plans, top and emerging risks, including those associated with climate change, capital position and liquidity and funding profile, stress scenarios, and contingent liabilities, and the reasonably possible changes in trading performance arising from potential economic, market and product developments. The Directors' assessment included consideration of the potential impacts arising from higher living costs.

Having assessed this information and the principal risks and uncertainties, the Directors are satisfied that the Santander UK group has adequate resources to continue operations for a period of at least 12 months from the date of this report and therefore consider it appropriate to adopt the going concern basis of accounting in preparing the financial statements.

**Ethical Code of Conduct**

Santander UK is committed to ensuring we hold ourselves to high ethical standards. This means adhering to laws, regulations, policies including our Ethical Code of Conduct and also carrying out business in a responsible way. High standards of professional and personal conduct helps Santander identify, manage and respond to risks, creates a positive, collaborative working environment and it ensures positive customer interactions and outcomes.

The Santander Way determines how we deliver on our purpose, to help people and businesses prosper. How we deliver that purpose is as important as the end result. Our conduct and our culture matters. Our aim is to be the best open financial services platform by acting responsibly and earning the lasting loyalty of our colleagues, customers and communities.

How we do business is intrinsically linked to our behaviours and values and supports our aim. Santander UK's Ethical Code of Conduct sets the standards expected of all colleagues and forms part of the terms and conditions of employment.

It makes clear our corporate values, our expectations regarding corporate behaviours and general principles and standards we expect with regard to customers, colleagues, conflicts of interest, data, media and our approach to sustainability.

There are numerous policies, processes, support and guidance that help colleagues meet these expectations and do the right thing to ensure Santander UK remains a Simple, Personal and Fair bank for its colleagues, customers, shareholders and the communities it serves.

The Ethical Code of Conduct applies to all colleagues including permanent and temporary colleagues as well as EDs and NEDs. The SEC requires companies to disclose whether they have a code of ethics that applies to the CEO and senior financial officers which promotes honest and ethical conduct, full, fair, accurate, timely and understandable disclosures, compliance with applicable governmental laws, rules and regulations, prompt internal reporting of violations, and accountability for adherence to a code of ethics.

Santander UK meets these requirements through its Ethical Code of Conduct and supporting policies, including but not limited to the Anti-Bribery and Corruption Policy, the Whistleblowing Policy, the FCA's Principles for Businesses, and the FCA's Statements of Principle and Code of Practice for Approved Persons, with which the CEO and senior financial officers comply.

Copies of these documents are available on application to Santander UK plc, 2 Triton Square, Regent's Place, London NW1 3AN.

**Disclosure of information to Auditors**

Each of the Directors at the date of approval of this report confirms that:

–So far as the Director is aware, there is no relevant audit information of which Santander UK's auditor is unaware

–The Director has taken all steps that they ought to have taken as a Director to make himself or herself aware of any relevant audit information and to establish that Santander UK's auditor is aware of that information.

This confirmation is given and should be interpreted in accordance with the provisions of Section 418 of the UK Companies Act 2006.

**Auditor**

PricewaterhouseCoopers LLP will continue in the office of auditor. A resolution to reappoint them will be proposed at the Company's forthcoming Annual General Meeting.

Risk governance

INTRODUCTION

Santander UK Group Holdings plc is the immediate parent company of Santander UK plc. The two companies operate on the basis of a unified business strategy with some overlap in membership, albeit the principal business activities of the Santander UK Group Holdings plc group are carried out by Santander UK plc and its subsidiaries. The Santander UK Group Holdings plc Risk Frameworks have been adopted by the Company and its subsidiaries to ensure consistent application.

As a financial services provider, managing risk is a core part of our day-to-day activities. To be able to manage our business effectively, it is critical that we understand and control risk in everything we do. We aim to use a prudent approach and advanced risk management techniques to help us deliver robust financial performance, withstand stresses, and build sustainable value for our stakeholders. We aim to keep a predictable medium-low risk profile, consistent with our business model. This is key to achieving our strategic objectives.

RISK FRAMEWORK

**How we define risk** (unaudited

Risk is any uncertainty about us being able to achieve our business objectives. It covers both financial and non-financial risks (NFRs). NFR is a broad term usually defined by exclusion, i.e. any risks other than the traditional financial risks of Credit, Market, Liquidity, Capital and Pension, and Strategic and business risk. Risk can be split into a set of risk types, each of which could affect our results and our financial resources. Enterprise risk is the aggregate view of all the risk types described below:

**Key risk types**

---

| | |
|:---|:---|
| Risk types | Description |
| **Credit** | The risk of financial loss due to the default or credit quality deterioration of a customer or counterparty to which we have provided credit, or for whom we have assumed a financial obligation. |
| **Market** | **Non-traded market risk** – the risk of loss of income, economic or market value due to changes to interest rates in the non-trading book or to changes in other market risk factors (e.g. credit spread and inflation risk), where such changes would affect our net worth through a change to revenues, assets, liabilities and off-balance sheet exposures in the non-trading book.<br>**Traded market risk** – the risk of changes in market factors that affect the value of positions in the trading book. |
| **Liquidity** | The risk that we do not have sufficient liquid financial resources available to meet our obligations as they fall due, or we can only secure such resources at excessive cost. |
| **Capital** | The risk that we do not have an adequate amount or quality of capital to meet our internal business objectives, regulatory requirements and market expectations. |
| **Pension** | The risk caused by our statutory, contractual or other liabilities with respect to a pension scheme (whether set up for our employees or those of a related company or otherwise). It also refers to the risk that we will need to make payments or other contributions with respect to a pension scheme due to an agreed Recovery Plan or for some other reason. |
| **Operational risk & resilience** | The risk of loss or adverse impact due to inadequate or failed internal processes, people and systems, or external events. We give a particular focus to Cyber, Fraud, IT, People and Third Party risks, which we mitigate through our management of operational risk.  |
| **Conduct and regulatory** | **Conduct risk** – the risk that our decisions and behaviours lead to detriment or poor outcomes for our customers. It also refers to the risk that we fail to maintain high standards of market behaviour and integrity.<br>**Regulatory risk** – the risk of financial or reputational loss, or imposition or conditions on regulatory permission, as a result of failing to comply with applicable codes, regulator's rules, guidance and regulatory expectations. |
| **Financial crime** | The risk that we are used to further financial crime, including money laundering, sanctions evasion, terrorist financing, facilitation of tax evasion, bribery and corruption. Failure to meet our legal and regulatory obligations could result in criminal or civil penalties against Santander UK or individuals, as well as affecting our customers and the communities we serve. |

---

In January 2023, the Legal risk framework, in agreement with the General Counsel, was retired following a structural change when the Chief Legal and Regulatory Officer (CLRO) left the organisation and the Legal function moved to the CFO Division (Line 1). As the Risk Types are owned by Risk control units (Line 2 in our three lines of defence model, as set out in 'Risk organisational structure' section that follows), and the CFO Division is a Risk management unit (Line 1), it was decided to retire the Legal risk type and framework. Where appropriate, elements of the existing Legal risk framework will be subsumed into the other relevant risk frameworks. Within the Risk Framework, the roles and responsibilities of CFO have been expanded to include the oversight of the General Counsel and Legal function, overseeing the provision of legal support to Santander UK, and management of relationships with third party law firms.

**Top and emerging risks** 

Several of our risk types also have Top risks associated with them. We regularly review the Top risks that could impact our business, customers and shareholders, and they are monitored at each meeting of the ERCC and BRC. The Top risks we actively monitored in 2022 are set out in the relevant section of this Risk review and summarised in the Top risks section of the Risk management overview in the Strategic report. Our Top risks included risks arising from Inflationary and supply chain pressures, Climate change, Financial crime, Fraud, IT, Cyber, People and Conduct and regulatory.

We also regularly review emerging risks that could impact our business, customers and shareholders, including regular review and discussion at the ERCC and BRC. The identification of emerging risks is co-ordinated by the Risk Division. A key part of the process is continual scanning of the external environment, focusing on emerging risk drivers such as broader geo-political, environmental and social risks, technology change, customer behaviour, market competition, regulation, government, digital assets and disruption of UK macroeconomic factors. Emerging risks actively monitored in 2022 are set out in the relevant section of this Risk review and summarised in the 'Emerging risks' section of the 'Risk management overview in the Strategic report.

In 2022 we added Eurozone/Sovereign Bank Contagion to the emerging risks we monitor and transitioned Inflationary and supply chain pressures to Top risks. For more, see the Risk management overview in the Strategic report.

**Key elements** 

Our Risk Framework sets out how we manage and control risk. In 2021, we enhanced some of the standards to provide more details and clarity on the relationship between, and roles of, Banco Santander SA and Santander UK, climate related risk drivers whether physical or transition-led, and the development of risk methodologies and quantitative models.

**How we approach risk – our culture and principles** 

The complexity and importance of the financial services industry demands a strong risk culture. We have systems, controls and safeguards in place to manage and control the risks we face, but it is also crucial that everyone takes personal responsibility for managing risk. Our risk culture plays a key role in our aim to be the best bank for our customers, shareholders, people and communities by acting responsibly. It is vital that all our people understand this. To achieve this, our people have a strong, shared understanding of what risk is, and what their role is in helping to control it. We express this in our Risk Culture Statement:

---

| |
|:---|
| Risk Culture Statement |
| Santander UK will only take risks that it understands and will always remain prudent in identifying, assessing, managing and reporting all risks. We proactively encourage our people to take personal responsibility for doing the right thing and to challenge without fear. We ensure decisions and actions take account of the best interests of all our stakeholders and are in line with The Santander Way. |

---

The Board reviews and approves our Risk Culture Statement every year. Senior executives are responsible for promoting our risk culture from the top. They drive cultural change and increased accountability across the business. We reinforce our Risk Culture Statement and embed our risk culture in all our business units through our Risk Framework, Risk Certifications and other initiatives. This includes highlighting that:

–It is everyone's personal responsibility to play their part in managing risk

–We must Identify, Assess, Manage and Report risk quickly and accurately

–We make risk part of how we assess our people's performance and how we recruit, develop and reward them

–Our internal control system is essential to ensure we manage and control risk in line with our principles, standards, Risk Appetite and policies.

We use Risk Certifications to confirm how we manage and control risks in line with our Risk Framework and within our Risk Appetite. As an example, every year, each member of our Executive Committee confirms that they have managed risk effectively in line with the Risk Framework in the part of the business for which they are responsible. Their certification lists any exceptions and the agreed actions to be taken to correct them. This is a tangible sign of the personal responsibility that is such a key part of our risk culture.

**Our risk culture programme – I AM Risk**

Our I AM Risk approach aims to make sure our people:

**–Identify** risks and opportunities <br>**–Assess** their probability and impact <br>**–Manage** the risks and suggest alternatives<br>**–Report**, challenge, review, learn and 'speak up'.<br>

I AM Risk is how we make risk management part of everyone's life as a Santander UK employee from how we recruit them and manage their performance to how we develop and reward them. It is also how we encourage people to take personal responsibility for risk to speak up and to come up with ideas. We use I AM Risk in our risk certifications, policies, frameworks and governance, and risk-related communications. We also include it in reward arrangements and in mandatory training. To support general awareness, our learning websites include videos and factsheets.

As part of I AM Risk, we include mandatory risk objectives for all our people in our performance management processes. The Executive Committee leads our culture initiatives under the CEO's sponsorship and we use monthly staff surveys to give insight into our culture.

**Our risk governance structure** 

We are committed to the highest standards of corporate governance in every part of our business, including risk management. For details of our governance, including the Board and its Committees, see the 'Governance' section of this Annual Report. The Board delegates certain responsibilities to Board Level Committees as needed and where appropriate. Our risk governance structure strengthens our ability to identify, assess, manage and report risks, as follows:

**–Committees:** A number of Board and Executive committees are responsible for specific parts of our Risk Framework

**–Key senior management roles:** A number of senior roles have specific responsibilities for risk management

**–Risk organisational structure:** We have the 'three lines of defence' model built into the way we run our business.

**Risk organisational structure** 

We use the 'three lines of defence' model to manage risk. This model is widely used in the banking industry and has a clear set of principles to put in place a cohesive operating model across an organisation. It does this by separating risk management, risk control and risk assurance. The reporting lines to the Board with respect to risk are as follows:

---

| |
|:---|
| Line 1: Risk management |
| Business Units and Business Support Units identify, assess and manage the risks which originate and exist in their area, within our Risk Appetite. It is under the executive responsibility of the CEO. |
| Line 2: Risk control |
| Risk Control Units are independent monitoring and control functions. They make sure Business Units and Business Support Units manage risks effectively and within our Risk Appetite. The Risk Control units are: Financial Crime, Risk - responsible for controlling credit, liquidity, capital, market, pension, strategic and business, operational, model and enterprise risks; and Compliance, responsible for controlling reputational and conduct and regulatory risks. It is under the executive responsibility of the CEO, but responsible to the CRO for overseeing the first line of defence. |
| Line 3: Risk assurance |
| Internal Audit is an independent corporate function. It gives assurance on the design and effectiveness of our risk management and control processes. It is responsible to the CIA. |

---

**Internal control system** 

Our Risk Framework is an overarching view of our internal control system that helps us manage risk across the business. It sets out at a high level the principles, standards, roles and responsibilities, and governance for internal control. Our Risk Framework covers the categories below:

---

| | |
|:---|:---|
| Category | Description |
| **Risk Frameworks** | Set out how we should manage and control risk across the business, our risk types and our risk activities. |
| **Risk Management Responsibilities** | Set out the Line 1 risk management responsibilities for Business Units and Business Support Units. |
| **Strategic Commercial Plans** | Plans produced by business areas, at least annually, which describe the forecasted objectives, volumes and risk profile of new and existing business, within the limits defined in our Risk Appetite. |
| **Risk Appetite** | See our Risk Appetite section that follows. |
| **Delegated Authorities/Mandates** | Define who can do what under the authority delegated to the CEO by the Board. |
| **Risk Certifications** | Business Units, Business Support Units or Risk Control Units set out each year how they managed/controlled risks in line with our risk frameworks and Risk Appetite, and explain any action to be taken. This helps drive personal accountability. |

RISK APPETITE

**How we control the risks we are prepared to take**

When our Board sets our strategic objectives, it is important that we are clear about the risks we are prepared to take to achieve them. We express this through our Risk Appetite Statement, which defines the amount and kind of risk we are willing to take. Our Risk Appetite and strategy are closely linked, and our strategy must be achievable within the limits set out in our Risk Appetite.

**The principles of our Risk Appetite**

Our Risk Appetite Statement lists ten principles that we use to set our Risk Appetite.

–We always aim to have enough financial resources to continue to do business in adverse but plausible stressed economic and business conditions, as well as to survive a very severe stress that would deplete our capital reserves

–We should be able to predict how our income and losses might vary – that is, how volatile they are. That applies to all our risks and lines of business

–Our earnings and dividend payments should be stable, and in line with the return we aim to achieve

–We are an autonomous business, so we always aim to have strong capital and liquidity resources

–The way we fund our business should be based on diverse funding sources and duration. This helps us avoid relying too much on wholesale markets

–We set controls on large concentrations of risk, like single customers or specific industries

–There are some key risks we take, but for which we do not actively seek any reward, like operational, conduct and regulatory, financial crime, legal and reputational risk. We take a risk-averse approach to these risks

–We comply with all regulations – and aim to exceed the standards they set

–Our pay and bonus schemes should support these principles and our risk culture

–We always aim to earn the trust of our people, customers, shareholders and communities.

**How we describe the limits in our Risk Appetite**

Our Risk Appetite sets out detailed limits across all types of risk, using metrics and qualitative statements.

**Metrics**

We use metrics to set limits across most risk types including a set of metrics focused on losses, capital, liquidity and concentration. We set:

–Limits for losses for our most important risks, including credit, market, operational and conduct risk

–Capital limits, reflecting both the capital that regulators expect us to hold (regulatory capital) and our own internal measure economic capital (EC)

–Liquidity limits according to a range of plausible stress scenarios for our business

–Concentration limits, to determine the maximum concentration level that we are willing to accept.

These limits apply in normal business conditions, but also when we might be experiencing a far more difficult economic environment. We refer to conditions like this as being under stress. For more on EC and stress scenarios, see the next page.

**Qualitative statements**

For some types of risk we also use qualitative statements that describe in words the appetite we want to set. For example, in operational risk, we use them to describe our risk-averse appetite for cyber risk. We also use them to prohibit or restrict exposure to certain sectors, types of customer and activities.

**How we set our Risk Appetite, and stay within it**

We control our Risk Appetite through our Risk Appetite Framework. Our Board approves and oversees our Risk Appetite Statement every year. This ensures it is consistent with our strategy and reflects changes in the markets and economic environment in which we operate. Our ERCC is responsible for ensuring that our risk profile (the level of risk we are prepared to accept) is consistent with our Risk Appetite Statement. To do this they monitor our performance against our Risk Appetite, business plans and budgets each month.

We also use stress testing to review how our business plan performs against our Risk Appetite Statement. This shows us if we would stay within our Risk Appetite under stress conditions. It also helps us to identify any adverse trends or inconsistencies.

We embed our Risk Appetite by setting more detailed risk limits for each business unit and key portfolios. These are set in a way so that if we stay within each detailed limit, we will stay within our overall Risk Appetite. When we use qualitative statements to describe our appetite for a risk, we link them to lower-level key risk indicators, so that we can monitor and report our performance against them.

STRESS TESTING

Stress testing helps us understand how different events and economic conditions could affect our business plan, earnings and risk profile. This helps us plan and manage our business.

**Scenarios for stress testing**

To see how we might cope with difficult conditions, we regularly develop challenging scenarios that we might face. We consult a broad range of internal stakeholders, including Board members, when we design and choose our most important scenarios. The scenarios cover a wide range of outcomes, risk factors, time horizons and market conditions. They are designed to test:

–The impact of shocks affecting the economy as a whole or the markets we operate in

–Key potential vulnerabilities of our business model, and the processes and systems which support it

–Potential impacts on specific risk types.

We describe each scenario using a narrative setting out how events might unfold, as well as a market and/or economic context. For example, the key economic factors we reflect in our ICAAP scenarios include house prices, interest rates, unemployment levels, inflation, and the size of the UK economy. We also explore sensitivities around several macro variables where there may be concerns or levels of uncertainty.

In 2021 and 2022, we completed the Bank of England's (BoE) Climate Biennial Exploratory Scenario (CBES). The purpose of this exercise was to investigate a range of risks that may not be directly linked to prevailing economic and financial conditions and helps us to prepare for possible future shocks. The CBES tested the resilience of the UK financial system to the physical and transition risks associated with three different climate pathways. The key climate factors included physical risks due to higher global temperatures, and transition risks due to the structural changes needed to transition to a low-carbon economy.

In 2022, we also developed a Climate Internal Scenario Analysis (CISA) to help understand better the potential impact of climate change on our business portfolios and balance sheet. We generated three qualitative scenarios for climate-related risks and we also quantified potential losses from an early disorderly transition, for example linked to the current energy crisis and conflict in Ukraine. The CISA outputs will form the basis of our 2022 ICAAP for climate risk by helping show if we need to hold more capital for climate-related risk and help us prioritise our actions for the next five years.

**How we use stress testing**

We use stress testing to estimate the effect of these scenarios on our business and financial performance, including:

–Our business plan, and its assessment against our Risk Appetite

–Our capital strength, through our ICAAP

–Our liquidity position, through our ILAAP

–Our long term impacts of climate change, through the CBES and our CISA

–Impacts on other risk types.

We use a wide range of models, approaches and assumptions. These help us interpret the links between factors in markets and the economy, and our financial performance. For example, one model looks at how changes to key macroeconomic variables like unemployment rates might affect the number of customers who might fall into arrears on their mortgage or other loans.

Our stress testing models are subject to a formal review, independent validation and approval process. We highlight the key weaknesses and related model assumptions in the approval process for each stress test. In some cases, we overlay expert judgement onto the results of our models. Where this is material to the outcome of the stress test, the approving governance committee reviews it. We take a multi-layered approach to stress testing to capture risks at various levels. This ranges from sensitivity analysis of a single factor to a portfolio, to wider exercises that cover all risks across our entire business. We use stress test outputs to design business plans that aim to mitigate potential impacts of possible stress scenarios.

We also conduct reverse stress tests. These are tests in which we identify and assess scenarios that are most likely to cause our business model to fail.

**Board oversight of stress testing**

The ERCC approves the design of the scenarios in our ICAAP, ILAAP and CISA. The BRC approves the stress testing framework. The Board reviews stress test outputs as part of the approval processes for the ICAAP, ILAAP, Bank Recovery and Resolution Directive (BRRD), our Risk Appetite and regulatory stress tests, including CBES.

**Regulatory stress tests** 

We take part in a number of external stress testing exercises. These can include stress tests of the UK banking system conducted by the PRA and the BoE. We also contribute to stress tests of Banco Santander conducted by the European Banking Authority (EBA).

For more on capital and liquidity stress testing, see the 'Capital risk' and 'Liquidity risk' sections.

HOW RISK IS DISTRIBUTED ACROSS OUR BUSINESS

**Economic capital**

As well as assessing how much regulatory capital we need to hold, we use an internal EC model to measure our risk. We use EC to get a consistent measure across different risk types. EC also takes account of how concentrated our portfolios are, and how much diversification there is between our various businesses and risk types. As a consequence, we can use EC for a range of risk management activities. For example, we can use it to help us compare requirements in our ICAAP or to get a risk-adjusted comparison of income from different activities.

**Regulatory capital – risk-weighted assets**

We hold regulatory capital against our credit, market and operational risks. In 2022, over half of our total risk-weighted assets accounted for credit risk in Retail Banking. This reflects our business strategy and balance sheet.

The segmental basis of presentation in this Annual Report has changed following the transfer of Social Housing loans and non-core liabilities to our CCB segment from Corporate Centre. Comparatives have been restated accordingly. See Note 2 for more information.

Our approach to credit risk

We manage our portfolios across the credit risk lifecycle, from drawing up our risk strategy and planning, through assessment and origination, monitoring, arrears management and debt recovery. We make sure the actual risk profile of our exposures stays in line with our business plans and within our Risk Appetite. We tailor the way we manage risk to the type of product and regularly review our approach and refine it when we need to.

**1. Risk strategy and planning** (audited)

All relevant areas of the business work together to create our business plans. We aim to balance our strategy, goals, and financial and technical resources with our Risk Appetite. To do this, we focus on economic and market conditions and forecasts, regulations, conduct matters, profitability, returns and market share.

**2. Assessment and origination** (audited)

Managing credit risk begins with lending responsibly. That means only lending to customers who are committed to paying us back and can afford to, even if their circumstances change. We undertake a thorough risk assessment to make sure a customer can meet their obligations before we approve a loan. We take proportionate steps to assess whether a customer will be able to repay the money borrowed. We do this by a series of initial affordability and credit risk assessments. We access each customer's credit profile and signs of how reliable they are at repaying credit. When a customer applies, we assess the data they provide, plus data from credit reference agencies (for Retail Banking and Consumer Finance) and performance on their other Santander accounts (if they have any) against our Credit Policy.

**Retail Banking** 

In Homes, for secured loans, we assess affordability by reviewing the customer's income and spending, their other credit commitments, and what would happen if interest rates went up. Many of our decisions are automated as we use data available to us. We tailor our process and application assessment based on the product. More complex transactions often need greater manual assessment using our credit underwriters' skill and experience.

In Everyday Banking, similar to Homes, many of our decisions are automated and we tailor the process based on the product. We assess affordability on a proportionate basis by reviewing the customer's income, spending stressed for future inflation, their total credit commitments and accommodation stressed for expected interest rates.

Credit risk mitigation

The types of credit risk mitigation, including collateral, across each of our portfolios are:

---

| | |
|:---|:---|
| Portfolio | Description |
| **Residential mortgages** | Collateral is in the form of a first legal charge over the property. Before we grant a mortgage, the property is valued either by a surveyor or using automated valuation methodologies where our confidence in the accuracy of this method is high. |
| **Unsecured lending** | There is no collateral or security tied to the loan that can be used to mitigate any potential loss if the customer does not pay us back. |
| **Business banking services** | Business banking lending is unsecured. When lending to incorporated businesses, we typically obtain personal guarantees from each director but we do not treat these as collateral. We consider the UK Government guarantee supporting losses on amounts lent under its Coronavirus Loan Schemes as collateral with 100% for Bounce Back Loan Scheme (BBLS) and 80% for Coronavirus Business Interruption Loan Scheme (CBILS). |

---

**Consumer Finance**

In Consumer Finance, similar to Retail Banking, many decisions are automated and we tailor the process to the product. Residual value risk is one of our top risks.

Credit risk mitigation

The type of credit risk mitigation, including collateral, is:

---

| | |
|:---|:---|
| Portfolio | Description |
| **Consumer (auto) finance** | Collateral is in the form of legal ownership of the vehicle for most loans, with the customer being the registered keeper. Only a very small proportion of business is underwritten as a personal loan. In these cases, there is no collateral or security tied to the loan. We use a leading vehicle valuation company to assess the LTV at the proposal stage to ensure the value of the vehicle is appropriate. |

---

**Corporate & Commercial Banking**

We assign each customer a credit rating according to the internal rating threshold, using our internal rating scale (see 'Credit quality' in 'Santander UK group level – credit risk review' section). To do this, we look at the customer's financial history and trends in the economy, backed up by the expert judgement of a risk analyst. We review our internal ratings on a dynamic basis and at least once a year for those clients that are rated. We also assess the underlying risk of the transaction, taking account of any mitigating factors (see the tables below) and how it fits with our risk policies, limits and Risk Appetite.

Responsible lending, including climate change and the transition to a low carbon economy

As part of the Banco Santander group, we comply with the Equator Principles to factor social, ethical and environmental impacts into our risk analysis and decision making for qualifying financial transactions. We are committed to supporting clients and economies in their transition to a low carbon economy, providing financial products and/or services to business activities that are environmentally and socially responsible. Our ESCC policy sets out how we identify, assess, monitor and manage environmental and social risks and other climate change related activities in the Oil and Gas, Power Generation and Mining and Metals sectors and those arising from businesses engaged in soft commodities. Our ESCC policy prohibits project-related financing for new coal-fired power plants (CFPP) worldwide and we will only work with new clients with CFPPs to provide specific financing for renewable energy projects. In line with Banco Santander's commitment, by 2030 we will eliminate all exposure to thermal coal mining and stop providing financial services to power generation clients with more than 10% of revenue from thermal coal. More information on our approach to Responsible Lending can be found in the Sustainability and Responsible Banking section.

Credit risk mitigation

The types of credit risk mitigation, including collateral, across each of our portfolios are as follows. In addition, from time to time at a portfolio level we execute significant risk transfer transactions, which typically reduce RWAs.

---

| | |
|:---|:---|
| Portfolio | Description |
| **SME and mid corporate** | Includes secured and unsecured lending. We can take mortgage debentures or a first charge on commercial property as collateral. Before agreeing the loan, we get an independent professional valuation of the property. Loan agreements typically allow us to obtain revaluations during the term of the loan. We can also take guarantees, but we do not treat them as collateral unless they are supported by a tangible asset charged to us. We also lend against assets (like vehicles and equipment) and invoices for some customers. We value assets before we lend. For invoices, we review the customers' ledgers regularly and lend against debtors who meet agreed criteria. |
| **Commercial Real Estate** | We take a first charge on commercial property as collateral. The loan is subject to criteria such as the property condition, age and location, tenant quality, lease terms and length, and the sponsor's experience and creditworthiness. Before advancing the loan and where appropriate, a bank representative visits the property, additionally we get an independent professional valuation which typically includes a site visit. Loan agreements typically allow us to obtain revaluations during the term of the loan. |
| **Social Housing** | We take a first charge on portfolios of residential real estate owned and let by UK Housing Associations as collateral, in most cases. We revalue this every three to five years (in line with industry practice), using the standard methods for property used for Social Housing. |

---

**Corporate Centre**

Credit risk mitigation

The types of credit risk mitigation, including collateral, across each of our portfolios are as follows. In addition, from time to time at a portfolio level we execute significant risk transfer transactions, which typically reduce RWAs.

---

| | |
|:---|:---|
| Portfolio | Description |
| **Sovereign and Supranational** | In line with market practice, there is no collateral against these assets. |
| **Structured Products** | These are our High Quality Liquid Assets (HQLA) in our Eligible Liquidity Pool. They are mainly ABS and covered bonds, which hold senior positions in the creditor hierarchy. Their credit rating reflects over-collateralisation in the structure and the assets that underpin their cash flows. |
| **Financial Institutions** | We use standard legal agreements to reduce credit risk via netting and collateralisation on derivatives, repos and reverse repos, and stock borrowing/lending. We also reduce risk by clearing trades through central counterparties (CCPs) where possible. |

**3. Monitoring** (audited)

We measure and monitor changes in our credit risk profile on a regular and systematic basis against our budgets, limits and benchmarks.

**Credit concentrations**

A core part of our monitoring and management is a focus on credit concentrations, such as the proportion of our lending that goes to specific borrowers, groups or industries. We set and monitor concentration limits in line with our Risk Appetite and review them on a regular basis.

–Geographical concentrations: We set exposure limits to countries and geographies, with reference to the country limits set by Banco Santander and our own Risk Appetite. For more geographical information, see 'Country risk exposures'.

–Industry concentrations: We also set exposure limits by industry sector. We set these limits based on the industry outlook, our strategic aims and desired level of concentration, and relevant limits set by Banco Santander. We analyse committed exposures in the 'Credit risk review' section that follows.

**Retail Banking** 

In Homes, we use IT systems and data available to us to monitor accounts. The main parts are:

–Behavioural scoring: we use statistical models that help predict whether a customer will have problems repaying, based on how they use their accounts

–Credit reference agencies: we often use data from agencies on how the borrower is handling credit from other lenders in our behaviour scoring models

–Other Santander accounts: each month, we also look at how the customer uses their other accounts with us, so we can identify problems early.

Our day-to-day retail credit risk monitoring relies on a mix of product, customer and portfolio performance measures as described above. However, changes in the wider UK economy also impact our Homes portfolio. As part of our day-to-day risk monitoring, we use a Retail Risk Playbook tolerance framework that sets out the most relevant macroeconomic variables to retail portfolio performance. We monitor these variables against our forecasts. If the economy deviates materially from our forecasts, such as due to the effects of the cost of living crisis, high inflation, we formally review our retail risk management policy and strategy.

Our monitoring can also mean we change our minds about whether a product is still right for a customer. If we find evidence that a customer is in financial difficulties, we contact them about arrears management including forbearance, which we explain in more detail below.

For secured lending, our monitoring also takes account of changes in property prices. We estimate the property's value every three months. In most cases, we use statistical models based on recent sales prices and valuations in that local area. Use of this model is subject to Model Risk Governance. Where a lack of data means the model's valuation is not available, we use the original surveyor valuation with a House Price Index (HPI) adjustment as needed.

In Everyday Banking, similar to Homes, we use IT systems and data available to us to monitor accounts, and we use the Retail Risk Playbook tolerance framework (except for business banking services) and management judgements to ensure that portfolio quality remains within Risk Appetite. For unsecured personal lending like credit cards and overdrafts, monitoring might lead us to raise or lower credit limits. For business banking services, we review revolving credit facilities each year to ensure the facilities remain appropriate for the customer's financial circumstances.

**Consumer Finance**

In Consumer Finance, similar to Retail Banking, we use IT systems and data available to us to monitor accounts, and we use the Retail Risk Playbook tolerance framework and management judgements to ensure that portfolio quality remains within Risk Appetite. We also check the Residual Value of our portfolio each month, using triggers set to identify any material change in trends.

**Corporate & Commercial Banking and Corporate Centre**

We regularly monitor and report our credit risk by portfolio, segment, industry, location and customer. We monitor detailed analyses of our credit exposures and risk trends each month. We also report our larger exposures and risks to the Board Risk Committee each month.

Our Watchlist

We also use a Watchlist for exposures subject to annual reviews to help identify potential problem debt early. Just because a customer is on our Watchlist does not mean they have defaulted. It just means that their probability of default has increased, such as they have breached a covenant or lost a major contract.

We classify Watchlist cases as:

–Enhanced monitoring: for less urgent cases. We monitor these cases more often and where appropriate may consider more collateral.

–Proactive management: for more urgent or serious cases. We may take steps to restructure debt including extending the term, taking more collateral, agreeing a lower credit limit, or seeking repayment of the loan through refinancing or other means.

We assess Watchlist cases for impairment as set out in the 'Significant Increase in Credit Risk (SICR)' section. When a customer is in enhanced monitoring, we do not consider it has suffered a SICR for ECL purposes, so it remains in Stage 1 for our loss allowance calculations. When a customer is in proactive management, we consider it has suffered a SICR, so we transfer it to Stage 2 and apply a lifetime ECL for our loss allowance calculations. We take into account any forbearance we offer. This includes any extra security, guarantees or equity available and the potential to enhance value by asset management.

In Corporate & Commercial Banking, as part of our annual reviews, for loans nearing maturity, we look at the prospect of refinancing the loan on current market terms and applicable credit policy. If this is unlikely, we put the case on our Watchlist.

We manage exposures not subject to annual reviews, mainly high volume and low value cases, using early warning indicators including credit reference agency data, supported by teams of expert analysts.

In Corporate Centre, we typically monitor the credit quality of our exposures daily. We use internal and third-party data to detect any potential credit deterioration.

**4. Arrears management** (audited)

**Retail Banking and Consumer Finance** 

We have several strategies to manage arrears that we can use as early as the day after a missed payment. We assess the problems a customer is having, so we can offer them the right help to bring their account up to date as soon as possible. The strategy we use depends on the risk and the customer's circumstances.

**Corporate & Commercial Banking and Corporate Centre**

We identify problem debt by close monitoring, supported by our Watchlist process for exposures subject to annual review. We aim to identify warning signs early by monitoring customers' financial and trading data, checking to see they do not breach covenants, and having regular dialogue with them. We tailor our strategy to the type of customer, their circumstances and the level of risk. We try to help our customers find their own way out of financial difficulty and agree on a plan that works for both of us. We engage our Restructuring & Recoveries team as needed on Watchlist cases and we may hand over more serious cases to them. For exposures not subject to annual review, we have strategies to manage arrears that can be used as early as the day of the missed payment. If a case becomes more urgent or needs specialist attention, and if it transfers to Stage 3, we transfer it to our Restructuring & Recoveries team.

For more, see the Forbearance section.

**5. Debt recovery** (audited)

Sometimes, even when we have taken all reasonable and responsible steps to manage arrears, they are not effective. If this happens, we have to end our agreement with the customer and try to recover the whole debt, or as much of it as we can.

**Retail Banking** 

In Homes, we may use a debt collection agency, sell the debt, or take the customer to court. For retail mortgages, we may repossess the property as a last resort or to protect it from damage or third-party claims. We make sure our estimated losses from repossessed properties are realistic by getting two independent valuations and the estimated selling costs, and using them in our loss allowances calculations. Where we repossess a property, we do not take ownership. We use agents to realise the value and settle the debt. Any surplus funds are returned to the borrower or dealt with in line with insolvency rules.

In Everyday Banking, we may use a debt collection agency, sell the debt, or take the customer to court, similar to our approach in Homes.

**Consumer Finance**

In Consumer Finance, similar to Retail Banking, we may use a debt collection agency, sell the debt, or take the customer to court. We may consider taking steps to re-possess the vehicles we have financed.

**Corporate & Commercial Banking and Corporate Centre**

Where we look for an exit, we aim to do this, if we can, by agreeing with the borrower that they will sell some or all their assets on a voluntary basis or agreeing to give them time to refinance their debt with another lender. Where we cannot reach an agreement, we consider recovery options. This can be through an insolvency proceeding, enforcing over any collateral or selling debt on the secondary market. We may also consider other legal action to recover what we are owed. If there is a shortfall, we write it off against our loss allowances. In very rare cases, we may act as mortgagee in possession of assets held as collateral against non-performing commercial lending. In such cases, we carry the assets on our balance sheet and classify them in line with our accounting policies.

**Loan modifications** (audited)

We sometimes change the terms of a loan when a customer gets into financial difficulty (this is known as forbearance), or for other commercial reasons.

**Forbearance** (audited)

We can change the terms of a customer's loan, temporarily or permanently, to help them through temporary periods of difficulty so they can get back on to sustainable terms. We assess what we offer to make sure the customer can afford it. Forbearance improves our customer relationships and we review our approach regularly to make sure it is still effective. We try to offer forbearance before a customer defaults and we only foreclose or repossess as a last resort.

The main types of forbearance we offer are:

---

| | |
|:---|:---|
| Action | Description |
| **Term extension** | We can extend the loan term, making each monthly payment smaller. We may offer this if the customer is up to date with payments but shows signs of financial difficulties. We may also offer this if the loan is about to mature and refinancing is not possible on market terms. |
| **Interest-only** | Prior to 2016, we offered retail customers temporary concessions to interest-only repayments due to financial difficulty. This concession is no longer available but any such loans that remain on interest-only repayment concession are classed as forborne. For corporate customers, we still consider interest-only concessions on a case by case basis. We only agree to this if we believe their financial problems are temporary and they are going to recover. After the interest-only period, we expect the customer to go back to making full payments of interest and capital once they are in a stronger financial position. |
| **Other payment rescheduling, including capitalisation** | For retail customers, we may add the arrears to the mortgage balance (this is known as capitalisation) if they cannot afford to increase their monthly payment to pay off their arrears in a reasonable time but have been making their monthly payments, usually for at least six months. We can also capitalise property charges due to a landlord. We pay them for the customer to avoid the lease being forfeited. We may combine this help with term extensions and, in the past, interest-only concessions. In certain cases we may also offer interest rate concessions.<br>For corporate customers, we may lower or stop their payments until they have time to recover. We may reschedule payments to better match the customer's cash flow – for example if the business is seasonal - or provide a temporary increase in facilities to cover peak demand ahead of their trading improving. We might do this by arrears capitalisation or drawing from an overdraft. We may also offer to provide new facilities, interest rate concessions and interest roll-up. In rare cases, we agree to forgive or reduce part of the debt. |

---

When we agree forbearance, we consider the account has suffered a SICR, as we explain later on, and we classify it as Stage 2 or 3. If an account is already in Stage 2, we keep it in Stage 2 unless the account is deemed unlikely to pay, involves forgiving fees and interest or debt, or is being granted multiple forbearances. In these cases, we move it into Stage 3. If an account is already in Stage 3, we keep it in Stage 3. A loan moves out of forbearance once the exit criteria below are met. We monitor the performance of all forborne loans.

Exit from forbearance or cure

For an account in Stage 3 to exit forbearance, all the following conditions must be met:

–The account has been classed as Stage 3 for at least one year since the end of the latest forbearance strategy

–The account is not deemed unlikely to pay

–The account is no longer in arrears, and the customer has no other material debts with us which are more than 90 days in arrears.

If all the conditions are met, the account is re-classed as Stage 2 forbearance until the Stage 2 forbearance exit conditions set out below are also met.

For an account in Stage 2 to exit forbearance, all the following conditions must be met:

–The account has been classed as Stage 2 for at least two years since the end of the latest forbearance strategy

–The account has been performing, i.e. the customer is no longer in financial difficulty

–Meaningful capital and interest repayments have been made for at least 50% of the two year period

–The account is no longer in arrears, and the customer has no other material debts with us which are more than 30 days in arrears.

**Other forms of debt management and modifications** 

When a customer is not showing signs of financial difficulties, we can also change their loan terms. We do this to help them manage their financial liabilities.

Retail Banking

In Homes, apart from forbearance, we have sometimes changed the contract terms to keep a good relationship with a customer. In Homes and Everyday Banking, we do not classify insolvency solutions for any unsecured retail customers as forbearance. This is in line with industry guidelines.

Consumer Finance

We do not classify insolvency solutions for any unsecured retail customers as forbearance. This is in line with industry guidelines.

Corporate & Commercial Banking and Corporate Centre

When customers are in financial difficulty, we can also manage debt in other ways, depending on the facts of the specific case:

---

| | |
|:---|:---|
| Action | Description |
| **Waiving or changing covenants** | If a borrower breaks a covenant, we can either waive it or change it, taking their latest and future financial position into account. We may also add a condition on the use of any surplus cash (after operating costs) to pay down their debt to us. |
| **Asking for more collateral or guarantees** | If a borrower has unencumbered assets, we may accept more collateral in return for revised financing terms. We may also take a guarantee from companies in the same group and/or major shareholders. We only do this where we believe the guarantor can meet their commitment. |
| **Asking for more equity** | Where a borrower can no longer pay the interest on their debt, we may accept fresh equity capital from new or existing investors to change the capital structure in return for better terms on the existing debt. |

---

**Risk measurement and control**

We measure and control credit risk at all stages across the credit risk lifecycle. We have a range of tools, processes and approaches.

**Retail Banking and Consumer Finance** 

These businesses involve managing large numbers of accounts, so they produce a huge amount of data. This allows us to take a more analytical and data intense approach to measuring risk. This is reflected in the wide range of statistical models we use across the credit risk lifecycle. We use:

–Risk strategy and planning: econometric models

–Assessment and origination: application scorecards, and attrition, pricing, loss allowance and capital models

–Monitoring: behavioural scorecards and profitability models

–Arrears management: models to estimate the proportion of cases that will result in possession (known as roll rates)

–Debt recovery: recovery models.

We assess and review our loss allowances regularly and have them independently reviewed. We look at factors such as the cash flow available to service debt. We also use an agency to value any collateral – mainly mortgages.

**Corporate & Commercial Banking and Corporate Centre**

We measure the credit risk on treasury products by adding their potential future exposure to market movements over their lives to their fair value. Then we add it to any other exposure and measure the total against our credit limits for each client. We assess our loss allowances regularly by looking at factors such as the cash flow available to service debt and the value of collateral based on third-party professional valuations.

**Key metrics** (audited)

We use a number of key metrics to measure and control credit risk, as follows:

---

| | |
|:---|:---|
| Metric | Description |
| **Expected Credit Loss (ECL)** | ECL tells us what credit risk is likely to cost us either over the next 12 months or over the lifetime of the exposure where there is evidence of a SICR since origination. We explain how we calculate ECL below. |
| **Stages 1, 2 and 3** | We assess each facility's credit risk profile to determine which stage to allocate them to, and we monitor where there is a SICR and transfers between the Stages including monitoring of coverage ratios for each stage. We explain how we allocate a facility to Stage 1, 2 or 3 below. |
| **Stage 3 ratio** | The Stage 3 ratio is the sum of Stage 3 drawn and Stage 3 undrawn assets divided by the sum of total drawn assets and Stage 3 undrawn assets. The Stage 3 ratio is the main indicator of credit quality performance. |
| **Expected Loss (EL)** | EL is based on the CRD IV regulatory capital rules and gives us another view of credit risk. It is the product of the probability of default, exposure at default and loss given default, and we include direct and indirect costs. We base it on our risk models and our assessment of each customer's credit quality. The rest of our Risk review, impairments, losses and loss allowances refer to calculations in accordance with IFRS, unless we specifically say they relate to CRD IV. For our IFRS impairment accounting policy, see Note 1 to the Consolidated Financial Statements. |

We also assess risks from other perspectives, such as geography, business area, product and process to identify areas to focus on. We also use stress testing to establish vulnerabilities to economic deterioration. Our business segments tailor their approach to credit risk to their customers, as we explain later on.

**Recognising ECL** (audited)

The ECL approach estimates the credit losses arising from defaults in the next 12 months on qualifying exposures, or defaults over the lifetime of the exposure where there is evidence of a Significant Increase in Credit Risk (SICR) since the origination date. The ECL approach takes into account forward-looking data, including a range of possible outcomes, which should be unbiased and probability-weighted to reflect the risk of a loss being incurred even when it is unlikely.

**Critical judgements and accounting estimates applied in calculating ECL** (audited)

The preparation of Santander UK's consolidated financial statements in accordance with IFRS requires management to make judgements, estimates and assumptions in applying the accounting policies that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based on amounts which differ from those estimates. Estimates, judgements and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. There has been no change in the inherent sensitivity of the areas of judgement in the period. Management have considered the impact of developments in principal risks and uncertainties, as set out in the Risk review, on critical judgements and accounting estimates.

The significant judgements, apart from those involving estimation, made by management in applying Santander UK's accounting policies in these financial statements (key judgements) and the key sources of estimation uncertainty that may have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities within the next financial year (key estimates), which together are considered critical to Santander UK's results and financial position, are as follows:

The application of the ECL impairment methodology for calculating credit impairment allowances is highly susceptible to change from period to period. The methodology requires management to make judgmental assumptions in determining the estimates. Any significant difference between the estimated amounts and actual amounts could have a material impact on the future financial results and financial condition. The impact of the cost of living crisis has increased the uncertainty around ECL impairment calculations and has required management to make additional judgements and accounting estimates that affect the amount of assets and liabilities at the reporting date and the amount of income and expenses in the reporting period. The key additional judgements due to the impact of the cost of living crisis mainly reflect the increased uncertainty around forward-looking economic data and the need for additional Judgemental Adjustments. We consider the critical accounting estimates in calculating ECL to be:

–Forward-looking multiple economic scenario assumptions; and

–Probability weights assigned to multiple economic scenarios.

We consider the critical management judgements in calculating ECL to be:

–Determining an appropriate definition of default;

–Establishing the criteria for a significant increase in credit risk (SICR) and for corporate borrowers internal credit risk rating;

–Determining the need for any Judgemental Adjustments (JAs);

– Determining the need to assess corporate Stage 3 exposures individually.

See the sections below for more on each of these key judgements and estimates.

**Multiple economic scenarios and probability weights** (audited)

For all our portfolios we use five forward-looking economic scenarios. For 2022, they consist of a central base case, one upside scenario and three downside scenarios. We use five scenarios to reflect a wide range of possible outcomes for the UK economy.

**Our forecasting approach**

We derive our scenarios in part by using a set of parameters in GDP fan charts published by the Office for Budget Responsibility (OBR). These fan charts reflect the probability distribution of a deviation from the OBR's central forecast to illustrate the uncertainty regarding the outcome of a variable, in this case GDP.

We use the 0.6 fan chart path for our Upside 1 scenario and the 0.3 path for Downside 1. For Downside 2 we impose a recession via an adjustment factor that converges to Downside 1 in the long-run, rather than imposing a floor on the peak to trough fall which had occurred prior to the pandemic. To ensure that Downside 2 is kept consistent with any changes to the OBR fan charts, we calculate the Downside 2 GDP by taking the percentage difference between Downside 2 and Downside 1 GDP in the original forecast and applying this difference to the new Downside 1.

Once we have established the GDP paths for each scenario, we run them through the Oxford Global Economic Model (OGEM) to derive the other macroeconomic variables, such as unemployment and house prices. These variables are the product of the GDP growth paths we have forecast and the output of the OGEM for these growth paths. These are then reviewed to ensure consistency with the narrative of each scenario and therefore changes to these variables may be required in some cases. We then impose a Bank Rate profile for each scenario using expert judgement. We determine the Bank of England Bank Rate by using the base case Bank Rate profile and adjusting this for each of the four other scenarios. To do this, we firstly consider what each of the scenarios is trying to achieve.

For the upside scenario, which has a slightly higher growth path, we assume a smaller increase in Bank Rate in 2023 with cuts beginning in 2024 in similar increments as the base case. For Downside 2 the scenario shows monetary policy being tightened to contain inflation at a time of weakening output growth, so here we assume the Bank of England raises rates to the same peak as in the base case to bring inflation back to its target rate, but that cuts start earlier as economic growth falls much more markedly and the Bank of England look to aid the economy. The rising Bank Rate profiles are based on forward guidance from the Bank of England, where increases are assumed to be gradual and incremental. For the Downside 1 scenario, this has a lower Bank Rate profile than in the base as the Bank of England look to bolster the economy earlier despite above target inflation rates, and for Stubborn Inflation, this reflects a larger increase in Bank Rate as inflation remains persistently above target. In this way, our scenarios reflect a range of possible outcomes that the Bank of England may follow for different growth paths, but also assumes that the Bank of England does not slash rates due to recessionary concerns.

Our use of five scenarios is designed to reflect different possible outcomes to the base case forecast highlighting the upside and downside risks associated with the central scenario. The downside risks for the UK economy include a further and sharper downturn in global growth, a substantial increase in inflation which raises the cost of living, a continuation of the very low productivity growth seen in the UK, and a move to a more protectionist agenda for trade. The upside risks were more muted at the end of 2022 and include a stronger recovery in global growth, a faster fall in inflation, coupled with a move to more open trade and further trade agreements with other countries.

We update the baseline in our economic scenarios at least twice a year in line with our annual budgeting and three-year planning processes, or sooner if there is a material change in current or expected economic conditions. For instance, in 2022 the base case has been updated every quarter. We refresh all our economic scenarios each quarter to reflect the latest data and OBR fan charts if these have changed, which are then reviewed and approved by the Credit Risk Provisions Forum (CRPF). The CRPF also assesses the probability weights at least once a quarter.

We do not use consensus forecasts as inputs to our models, but we do compare the outputs of our models against consensus views for the base case, to make sure that we understand any significant differences and address them where needed. At the end of 2022, there were no significant differences between our base case forecasts and the consensus views.

In 2022, we were also able to do further peer benchmarking analysis of the economic scenarios using the data the PRA provided, which for Q4 2022 included the mean weighted analysis for a selection of economic variables, including GDP, unemployment rate and HPI. This meant that we could compare our weighted scenarios against the average of our peers to understand what differences there may be. The conclusion of this analysis demonstrated that our economic scenarios were in line with our peers although, on a weighted basis, our house price inflation assumption reflected a more conservative view.

In 2022, we also considered any likely impact from climate change risk on our forecasting approach and concluded that no adjustment to the multiple economic scenarios for climate change risk was required. This is because climate change effects are generally regarded to be relevant over a longer timeframe than our forecast period of five years.

Our forecasting period for GDP is five years and then we revert to the average trend growth over three years based on the OBR's long-run GDP forecast assumption. The reversion to mean for all macroeconomic variables is expected to take three years after the initial five-year forecast period.

**Key changes to our forecasting approach in 2022**

In 2022, there were no specific changes to our forecasting approach. The OBR returned to publishing its fan charts and the latest version, published in March 2022, have been incorporated.

**Base case**

For our base case, the forecasts include a 6 quarter recession with a peak to trough fall in GDP of c.2%, caused by falling real disposable incomes due to the cost of living crisis and higher interest rates which push up housing costs. The forecasts also incorporate the policies set out in the Autumn Statement, including the changes to the Energy Price Guarantee scheme. It is normal practice to review the scenarios and associated weights every quarter to ensure they appropriately reflect the current economic circumstances, and we will continue to follow that approach particularly as the advice the UK Government issues is subject to change in this fluid environment.

|:---|
| Base case key macroeconomic assumptions |
| **–House price growth:** The housing market was surprisingly resilient in the first half of 2022. However, the sharp rise in mortgage rates has triggered a slowdown in house price growth in recent months. With survey indicators pointing to a sharp reduction in demand as buyer confidence is hit by a squeeze on affordability from higher inflation, taxes and mortgage rates, house prices are expected to continue declining in the near-term. We are forecasting a 10% year-on-year decline in house prices by the end of 2023, with zero growth anticipated by the end of 2024. Once the Bank Rate moves towards its neutral level, house price growth starts to pick up and by the end of the forecast period is in line with long term average earnings growth. |
| **–GDP:** The GDP forecasts for Q3 showed negative growth of -0.3% q/q and there is a high likelihood of a further contraction in Q4 which would push the UK economy into recession. The Q3 data showed that households and businesses are reducing spending to deal with rising costs, particularly of essential goods such as food and energy. All of this is likely, along with additional costs, to weigh on businesses with some firms falling into insolvency and there are examples of this being reported in Q4. The economy is expected to officially be in recession by the end of 2022 and for all of 2023, with growth remaining weak in 2024. While support from the Autumn Statement was reduced in some areas, for example with energy costs, there was some positive news for those on benefits and receiving the state pension, with both increasing in line with September's inflation rate of 11.1% and with the minimum wage also set to increase in April 2023. This should help support household spending and prevent a deeper economic downturn than the c.2% decline we expect. |
| **–Unemployment rate:** Unemployment rose to 3.7% in the 3 months to October as labour demand started to soften and inactivity among early retirees fell. However, the large increase in inactivity due to ill health or workers opting for early retirement is keeping unemployment rates low. Vacancies remain at high levels although they are continuing to fall back as demand of goods and services declines. With the effect of rising energy costs and interest rates, it is likely that labour demand will fall back further as some firms become insolvent and others find that demand for goods and services reduce as households restrict spending as real earnings fall. Whilst the forecast does not assume a large rise in unemployment, the rate peaks at 5.1% by end of 2024 as labour demand and supply conditions change, including previously inactive workers returning to the labour force. |
| **–Bank Rate:** For the Bank Rate forecast, the last actual data point for 2022 was December when the MPC increased rates by 50bps to 3.50% in line with expectations. This was followed by another 50bps rise to 4.00% in February, with two members voting in favour of no change. Our base case assumes that in Q1 2023 there will be no additional rises. Rate cuts start in Q2 2024 as inflation starts to fall back and the MPC looks to boost flagging growth. Bank Rate ends 2024 at 3.25%, with further cuts in 2025 leaving the terminal rate at 2.50% over the medium-term. |

---

In the medium-term, the projections assume that current demographic and productivity trends will continue, causing a reduction in the UK's growth potential. For instance, it is likely that the reduction in the UK workforce continues and that this will have a knock-on impact for the economy, particularly if there are shortages of skilled workers in particular sectors. This is reflected in an average annual growth expectation of 1.6%, the OBR's latest estimate of the UK's long run average growth rate. CPI inflation is forecast to be significantly above the 2% target rate in the initial forecast period but then falls to target by the end.

Key changes to our base case in 2022

The key changes to our base case assumptions in 2022 were: (i) weaker GDP growth in 2023 and 2024 which largely reflects the bigger hit to consumer spending from the squeeze on real incomes; (ii) higher and longer above target inflation in response to rising food, fuel and utility bills; (iii) a steeper Bank Rate profile with rates now reaching 4% in 2023, with cuts starting in 2024. This had the effect of increasing the weighted average Bank Rate profile across the five scenarios to 4.29%; and (iv) house prices are 10% lower by the end of 2023.

**Other scenarios**

Based on this revised base case, we have reviewed our suite of scenarios to ensure that they capture the wide range of potential outcomes for the UK economy. These include (i) reflecting persistent above target inflation over the forecast period; (ii) a slower recovery that is more akin to the 'U' shape of past recessions; (iii) labour market frictions due to skills mismatches and a shrinking workforce as some discouraged workers leave altogether (for example EU workers returning to their native countries and older UK-born workers retiring early); and (iv) the global economy recovering more swiftly from higher inflation.

To reflect these potential outcomes, we decided to continue to use the base case and four additional scenarios, which management considers provides a range wide enough to reflect all the above potential outcomes. However, as the risks remain skewed to the downside, to reflect these outcomes sufficiently, we concluded that only one upside scenario would be needed to reflect the upside risks to the base case. As with the base case, the scenarios are forecast over a five-year period and then mean revert over the next three years to the OBR's latest estimate of the UK's long run average growth rate.

The four other scenarios are:

One upside scenario

This scenario has a quicker recovery than the Baseline although remains benign. It assumes that inflation falls back more swiftly than in the base case, with a quicker end to the Ukraine conflict which helps to reduce gas and food prices. This allows the Bank of England to cut rates bringing them back to what is more likely to be the neutral rate, with households using some of the additional levels of saving accrued over the pandemic. This results in higher consumer and business confidence enabling higher levels of spending with savings rates falling back as real earnings growth returns. House prices fall marginally more than the base case, mainly due to the implied relationship between GDP and HPI used by the Oxford Economics model compared to that used by Management to construct the base case.

Three downside scenarios

**Downside 1** - This scenario is a bear case to the baseline. It assumes that peak to trough economic growth is lower and that the path out of recession is weaker. In this scenario excess savings are not used to support growth as consumer confidence remains extremely low, with households worried over the prospect of losing their job. House prices fall further than in the base case as more households look to downsize to lower mortgage repayments. Although inflation remains significantly above target, due to the very poor economic conditions, the Bank of England decides to cut Bank Rate earlier than in the base case to try and bolster growth.

**Downside 2** - This scenario is similar in severity to a typical stress test scenario. It shows a marked fall in GDP, with unemployment rising to levels consistent with the Global Financial Crisis (GFC) and house prices falling by almost a third as real incomes are squeezed by higher mortgage rates, inflation and taxes, which in turn hits buyer affordability. The scenario also reflects ongoing strike action by various unions pushing for larger pay growth, along with dealing with potential blackouts and the possibility of curtailed working weeks to deal with the energy supply shortage over the winter months. It further assumes that the incidence of major risk events, for example those caused by climate change, continue to occur exposing risks to countries' fiscal position and the means to respond to such events. For this scenario an overlay to the unemployment rate was also made to the model output from the OGEM. This was to account for the possibility of a recession of similar magnitude to that of 2008/09 where the unemployment rate peaked at 8.5%.

Key changes to our alternative scenarios in 2022

The key changes in 2022 were to Stubborn Inflation, which was changed from a pandemic scenario to one considering the effects of persistently above target inflation; to the Bank Rate profile of the scenarios to reflect current levels; and changes to the base case, historical data for each variable, and the OGEM. We did not make any other methodological changes to the scenarios. The combination of these different inputs will mean differences across the variables for each of the alternative scenarios when we update them each quarter. We continue to compare the variables between each quarter and review any large changes to ensure they are not erroneous.

**Scenario weights**

Each quarter, we undertake a full review of the probability weights we apply to the scenarios. We consider the probability of the economic scenarios occurring, while ensuring that the scenarios capture the non-linear distribution of losses across a reasonable range. To support our initial assessment of how likely a scenario is to occur, we typically undertake a Monte Carlo analysis which would ascertain the likelihood of a five-year average GDP forecast growth rate occurring based on the long run historically observed average. Creating a standard distribution bell curve around this long run average allows us to estimate the probability of a given GDP scenario occurring and therefore assign a probability weight to that scenario. However, a key challenge with this approach in a stressed environment like the one seen in 2020 is that extreme GDP forecasts can occur.

We continue to use the entire historical GDP data set available for the Monte Carlo analysis to smooth out the large GDP data swings that the pandemic gave. For 2022, the base case sits around the 20th percentile as growth is lower now that a further recession is predicted. Under the longer period, the Downside 2 scenario, which has the lowest CAGR, now sits below the 10th percentile suggesting that a lower weight than the base case remains appropriate.

We also need to consider the UK economic and political environment when applying weights. Given the current cost of living crisis, we remain of the view that the risks to UK growth are still biased to the downside and include: a substantial increase in inflation staying above target for longer, which raises the cost of living reducing consumer demand; continuing weak investment reflecting the turbulent political global environment; further development of Covid strains that are immune to vaccines leading to further restrictions; a larger negative impact from the EU trade deal given ongoing issues such as in NI; a continuing and significant mismatch between vacancies and skills along with a smaller labour force; and the increasing possibility of a second Scottish referendum which may bring disruption to any recovery in the latter years of the forecast. As such, it remains appropriate to reflect this with a 45% cumulative weighting for the downside scenarios. In contrast to last year, Downside 3 (i.e. the stubborn inflation scenario) has a heavier weight compared to downside 1 and 2 as this scenario is more representative of the current climate of potential stagflation.

The scenario weights we applied for 2022 and 2021 were:

---

**Definition of default (Credit impaired)** (audited)

We define a financial instrument as in default (i.e. credit impaired) for purposes of calculating ECL if it is more than three months past due, or if we have data that suggests the customer is unlikely to pay. The data we have on customers varies across our business segments. It typically includes where:

---

| |
|:---|
| Retail Banking and Consumer Finance |
| –They have been reported bankrupt or insolvent and are in arrears |
| –Their loan term has ended, but they still owe us money more than three months later |
| –They have had forbearance while in default and have failed to perform under the new arrangement terms, or have had multiple forbearance. Performing forborne accounts while not in default are reported in Stage 2 |
| –We have suspended their fees and interest because they are in financial difficulties |
| –We have repossessed the property. |
| Corporate & Commercial Banking and Corporate Centre |
| –They have had a winding up notice issued, or something happens that is likely to trigger insolvency – such as another lender calls in a loan |
| –Something happens that makes them less likely to be able to pay us – such as they lose an important client or contract |
| –They have regularly missed or delayed payments, even though they have not gone over the three-month limit for default |
| –Their loan is unlikely to be refinanced or repaid in full on maturity |
| –Their loan has an excessive LTV that is unlikely to be resolved, such as by a change in planning policy, pay-downs, or increase in market value |
| –Loans restructured under financial difficulties, classified as forborne transactions, in last 12 months. |

---

Where we use the advanced internal ratings-based basis for a portfolio in our capital calculations, there are differences with the default definitions for ECL purposes. The main differences are as follows:

–Performing forborne accounts while not in default are in Stage 2 until they cure their forbearance status (measured as 12 consecutive months of successful payments).

–Performing non-forborne accounts, which under our internal rating-based basis are subject to a 3-month cure period, for accounting purposes we classify them in Stage 2 until they cure all SICR triggers.

The CRPF reviews and approves the definition of default each year, or more often if we change it.

Following the implementation of a new regulatory definition of default in early 2022, we updated and aligned our definitions. This increased the Stage 3 ratio by 7bps (£0.2bn). This was due to including non-performing forbearance accounts which were previously reported in Stage 2 and are now reported in Stage 3 in line with unlikeliness to pay definitions, subject to a 12-month probation period in line with our regulatory default definition. The change in definition was a change in estimate and therefore prior periods have not been amended.

**Significant Increase in Credit risk (SICR)** (audited)

Loans which have suffered a SICR since origination are subject to a lifetime ECL assessment which extends to a maximum of the contractual term of the loan, or the behavioural term for a revolving facility. Loans which have not experienced a SICR are subject to 12-month ECL. We assess the credit risk profile of each facility to determine which of three stages to allocate them to:

**–Stage 1:** when there has been no SICR since initial recognition. We apply a loss allowance equal to a 12-month ECL i.e. the proportion of lifetime expected losses that relate to that default event expected in the next 12 months

**–Stage 2:** when there has been a SICR since initial recognition, but the exposure is not considered credit impaired. We apply a loss allowance equal to the lifetime ECL i.e. the expected loss resulting from all possible defaults throughout the residual life of a facility

**–Stage 3:** when the exposure is considered credit impaired. We apply a loss allowance equal to the lifetime ECL. Objective evidence of credit impairment is required. For more, see the section 'Definition of default (Credit impaired)' above.

We use quantitative, qualitative and backstop criteria to identify exposures that suffer a SICR. The Credit Risk Provisions Forum (CRPF) reviews and approves our SICR thresholds periodically. The Board Audit Committee reviews and challenges their appropriateness each year, or more often if we change them.

**Quantitative criteria**

We use quantitative criteria to identify where an exposure has increased in credit risk. We base our criteria on whether any increase in the lifetime PD since origination exceeds a threshold in relative and absolute terms. We base the value anticipated at origination on similar assumptions and data to the ones we use at the reporting date, adjusted to reflect the account surviving to that date. The comparison uses either an annualised lifetime PD, where the lifetime PD is divided by the forecast period, or the absolute change in lifetime PD since origination. Our criteria are absolute (rather than relative) increases in lifetime PD since origination. We also apply a relative threshold of 100% (doubling the PD) across all portfolios. The criteria for 2022 were:

(1)For larger business banking customers we apply the same criteria that we use for Corporate & Commercial Banking.

(2)Consumer Finance use the comparison of lifetime PDs to determine Stage allocation, unlike other products which first turn the lifetime PD into an average yearly PD (annualised) and then do the comparison.

(1)&nbsp;&nbsp;&nbsp;&nbsp;For larger business banking customers we apply the same criteria that we use for Corporate & Commercial Banking.

An additional qualitative assessment was introduced as part of new Judgemental Adjustment introduced during 2022 in response to the cost of living crisis. Exposures that were deemed more significantly impacted by cost-of-living pressures based on indebtedness and disposable income thresholds were migrated to Stage 2. See 'Judgemental Adjustments (JAs) below for more on this.

**Backstop criteria**

As a backstop, we classify all exposures more than 30 or 90 DPD in at least Stage 2 or in Stage 3, respectively. This means that we do not rebut the backstop presumptions in IFRS 9 (i.e. credit risk has significantly increased if contractual payments are more than 30 DPD) relating to either a SICR or default.

**Improvement in credit risk or cure**

We transfer Stage 3 exposures to Stage 2 or Stage 1 when we no longer consider them to be credit impaired. We transfer Stage 2 exposures to Stage 1 when we no longer consider them to have suffered a SICR. Where we identified a SICR using quantitative criteria, we transfer the exposures to Stage 1 when they no longer meet the original PD-based transfer criteria. Where we identified a SICR using qualitative criteria, the issues that led to the transfer must be cured before we transfer the exposure to Stage 1. For a loan to exit forbearance, it must meet the conditions set out in the section 'Forbearance'.

**Judgemental Adjustments (JAs) formerly known as Post Model Adjustments (PMAs)** (audited)

We use a range of methods to identify whether we need a JA. These include regular review of model monitoring tools, changes in the period, trend analysis, comparison against forecasts, and input from expert teams who manage key portfolio risks. We only recognise a JA if its expected impact is over £1m and keep it in place until we no longer need it. This is usually when we build it into our core credit model or the conditions that impacted the historical data no longer exist.

Our Risk Provisions & Forecasting team calculates JAs to ensure they are incremental to the core credit model and to ensure the calculation is performed in a consistent and controlled manner. We apply standard end-user computing controls to JAs expected to be in place for more than six months. Our Independent Validations Team may also review significant JAs. The CRPF approves all new JAs and, each quarter, reviews and approves existing JAs.

–**Long-term indeterminate arrears:** To mitigate the risk of model underestimation, we fully provide for accounts in arrears which have neither repaid (cured) or been written-off after a period of 2 years for unsecured portfolios or 5 years for secured portfolios. For our secured portfolios, we use expected security valuations at the point of repossession to estimate the adjustment. At 31 December 2022 and 31 December 2021, we only needed to make an adjustment for mortgages. When calculating the ECL uplift for this JA, management assumes a 2 year delay in the time to repossessions which reflects experience and ensure the LTVs are impacted by our Multiple scenario forecasts for HPI. Over the medium term, as we continue to address long term arrears in the portfolio, we expect the need for this JA will diminish. This JA increased our ECL by £13m . Had management assumed no delay in repossessions or a 3 year delay, the JA could have been within a range of £12m to £14m.

**–12+ months in arrears:** To mitigate the risk of underestimating ECL, mortgage accounts which are more than 12 months past due are fully provided for after deducting a historically observed self-cure rate. When calculating the ECL uplift for this JA, management assumes a 2 year delay in the time to repossessions which reflects experience and ensure the LTVs are impacted by our Multiple scenario forecasts for HPI. Over the medium term, as we continue to address long term arrears in the portfolio, we expect the need for this JA will diminish. This JA increased our ECL by £22m. Had management assumed no delay in repossessions or a 3 year delay, the JA could have been within a range of £7m to £28m.

–**Cladding risk:** Following the Government's intervention to support the owners of flats where cladding rectification may be required, we released this JA.

**–Mortgages affordability:** This JA addresses the risk that the current PD model for mortgages is likely to underestimate a 'cost of living crisis' whereby real disposable income is stretched with increasing living costs and debt burden as interest rates begin to rise. The JA identifies a population of customers most likely to be under inflationary pressures, increases their PDs and moves them to Stage 2. At 31 December 2022, these accounts made up a significant amount of the total mortgage Stage 2 population as £5.0bn mortgages were moved from Stage 1 into Stage 2 as a result. The JA increased our ECL by £9m in 2022 with a closing ECL of £27m .

**–Affordability of unsecured lending repayments**: We introduced new JAs to account for the potential repayment affordability risk among those customers with low disposable income. These JAs increased our ECL by £35m. Had management applied different sensitivities to the PD uplifts across Mortgages and Retail unsecured affordability, the ECL impact could have been between £49m and £82m.

–**UPL loss floor:** This JA addresses the perceived macroeconomic insensitivity within the UPL IFRS 9 models, where historical analysis of losses shows a much larger correlation to the International Labour Organisation (ILO) unemployment forecast than the model gives. The JA then uplifts the lifetime losses expected in each of the five macroeconomic scenarios within the IFRS 9 model to meet the expected losses the historical analysis predicts. The JA increased our ECL by £15m . If management had only increased PDs, the JA could have been £12m.

–**Model underestimation:** This JA addresses potential underestimation risk of projected modelled ECL identified by our model monitoring and back-testing from lower PDs given the low level of macroeconomic stress and timing effects of government support schemes on emergence of defaults. At 31 December 2022, this JA increased our ECL by £57m. Had management applied the same PD uplift on the upside 1 scenario the JA could have been £49m. Had management applied the same PD uplift on the Downside 3 scenario as the Base case, Upside 1 and Downside 1 scenarios, the JA could have been £60m.

**–Corporate lending to segments affected by supply chain:** We introduced new JAs to reflect the corporate lending risks to those sectors which are susceptible to high inflation and energy prices, higher input costs, potential for lower consumer and business demand, as well as exposure to supply chain challenges. This JA calculates ECL depending on the customer's risk profile in stage 1 and moves risk between stage 1 and 2 (resulting in increase in lifetime vs 12m ECL). In case of those clients already in stage 2 the JA is calculated by stressing PD levels according to the risk profile of the customer. In total this JA increased our ECL by £61m. The range for this JA can be between £26m to £187m depending on PD assumptions of high and severe sectors.

**–Corporate lending to segments affected by Covid-19:** In 2022, following a successful 18 month probation period, with no material observed defaults, we released all corporate sector staging JAs related to Covid-19 as the risks from lockdowns have reduced.

–**Corporate single large exposure:** In 2020, to mitigate against the risk of a single large corporate exposure with an ECL requirement of greater than £10m defaulting, which has not been covered by the existing model estimate or the corporate and SME JA above, we applied a JA for the risk of a company which unexpectedly defaults. This JA has been calculated based on incurring two average historically observed single name large losses in our Corporate & Commercial business segment. We will continue to assess this risk over the medium term based on actual experience and we will refine the estimate based on changes in our portfolio credit quality and loan size mix. At 31 December 2021, this JA increased our ECL by £23m . Had management assumed only one average loss was incurred the JA would decrease to £12m. The JA would increase to £35m assuming three average losses were incurred. It has been assessed and decision made to keep this JA as it is felt there is still a need for this given we are the start of a conventional recessionary environment. It is believed that the unprecedented support provided by the government over the last 2 to 3 years have differed stresses and accounted for the lack of any actual examples where we would have looked to utilise this JA.

**–SME debt burden:** We introduced a SME debt burden JA in 2021 to take account of the potential debt burden risk of unsecured lending to our SME customers who also took a BBL. This does not incorporate the credit risk on BBLs, as these are government guaranteed but instead considers the possible impact on repayment of other lending with us. At 31 December 2022, this JA increased our ECL by £7m . Had management used the modelled lifetime losses for all dragged accounts, the JA could have been £3m. Had management used a 50% coverage on all accounts, the JA could have been £15m.

–**Other:** This includes adjustments for other exposures in smaller portfolios that are not within models such as Buy To Let Mortgages. The year on year movement is driven by the absence of a £32m underlay JA which corrected an overstatement of the core modelled ECL as a result of customers who took a payment holiday artificially inflating stage 2. This was released in 2022 as the data distortion no longer impacted the modelled ECL.

**Climate change**

In addition 2022 and 2021,we assessed the risks to asset valuations in the customer loan book from both transitional and physical risks associated with climate change. At 31 December 2022 and 2021, we did not consider it appropriate to recognise a climate change risk related JA for the following reasons:

–The behavioural life of the loan book is less than five years. Any material transitional risks are generally regarded to be relevant over a longer timeframe than five years and as such, the risk predominantly relates to assets yet to be written;

–There have been no observed default events or SICRs due to climate change for any part of the loan book;

–The absolute exposure to fossil fuel industries is not deemed to be material. On an individually assessed basis, clients in these industries are highly rated and their markets remain highly liquid;

–The residual value of automotive vehicles might be impacted by diesel obsolescence and the transition to electric vehicles.The residual value risk is already set at the more cautious end of the acceptable range to capture the inherent risk of diesel obsolescence and measurement uncertainty of electric vehicles;

–ECL calculations are based on multiple forward-looking economic scenarios developed by management covering a period of 5 years, during which timeframe climate change risks may crystallise;

–The proportion of mortgage loans subject to flood and subsidence risk is not deemed to be material. The terms of our mortgage lending also require homeowners to buy suitable insurance which transfers the majority of the risk to asset valuations to third party insurers.

2022 compared to 2021

JAs reduced from £340m to £296m and the proportion of JAs to total ECL decreased from 39% to 29%. The change in proportion was mainly due to an increase in total ECL driven by the deterioration in the economic environment compared to 2021.

**Internal credit risk rating for corporate borrowers** (audited)

We assign each corporate borrower an internal credit rating based on our internal rating scale. To do this, we look at the customer's financial history and trends in the economy backed up by the expert judgement of a risk analyst. We review our internal ratings on a dynamic basis and at least once a year. The internal risk rating is used to determine the Probability of Default for a client.

**Individually assessed corporate Stage 3 exposures** (audited)

We assess the ECL requirement for large single name corporate exposures on an individual basis when they meet our definition of default and are transferred into Stage 3. This assessment takes into consideration the latest specific information about the counterparty to determine a probability weighted ECL based on a best, worst and mid case outcome. For those loans that were in default (i.e. Stage 3), the ECL was £129m at 31 December 2022 (2021: £100m). Had management assumed the best or worst outcome in terms of loss estimates, the ECL could have been within a range of £68m to £203m.

**Sensitivity of ECL allowance** (audited)

The ECL allowance is sensitive to the methods, assumptions and estimates underlying its calculation. For example, management could have applied different probability weights to the economic scenarios. In addition, the ECL for residential mortgages is significantly affected by the HPI assumptions which determine the valuation of collateral used in the calculations.

Had management used different assumptions on probability weights and HPI, a larger or smaller ECL charge would have resulted that could have had a material impact on the ECL allowance and profit before tax. We have incorporated judgemental adjustments (JA's) into the sensitivity analysis, and these assumptions are set out below.

**Scenario sensitivity**

The tables below show the ECL allowances that would have arisen had management applied a 100% weight to each economic scenario. The allowances were calculated using a stage allocation appropriate to each scenario and differs from the probability-weighted stage allocation used to determine the ECL allowance shown above. For exposures subject to individual assessment, the distribution of ECL which could reasonably be expected has also been considered, assuming no change in the number of cases subject to individual assessment, and within the context of a potential best to worst case outcome.

2022 compared to 2021

In 2022 ECL increased as a result of PD deterioration and an introduction of affordability JAs mainly due to changes in the current economic environment. As a risk from further lockdowns relating to Covid19 reduced, we released all Corporate Covid19 related JAs. This release resulted in the movement of £0.4bn corporate Stage 3 loans to Stage 2 and £1.7bn of corporate loans transferred from Stage 2 to Stage 1. However, this was offset by an introduction of a new corporate lending JA relating to segments that are susceptible to high inflation and energy price, higher input costs, potential for lower consumer and business demand. This resulted in movement of £1.4bn from Stages 1 to 2. Mortgage affordability continued to be impacted by the increased base rate and inflationary pressures, resulting in an increase in Stage 2 mortgage asset by £0.8bn.

We have incorporated our JA's into the sensitivity analysis.

**HPI sensitivity** 

Given the relative size of our residential mortgage portfolio, management considers that changes in HPI assumptions used to calculate the ECL allowance for residential mortgages would have the most significant impact on the ECL allowance. The table below shows the ECL impact on the profit before tax of applying an immediate and permanent hour price increase/decrease to our unweighted base case scenario, and assumes no changes to the stage allocation of exposures.

2022 compared to 2021

The HPI ECL sensitivity remains similar to 2021. The expected impact from a drop in the HPI index by 10% and 20% is £61m and £176m respectively. There has been moderate growth for 2022 coupled with a negative economic outlook that has resulted in potential losses increasing towards the end of the year.

Both the modelled ECL and the PMAs were stressed in the sensitivity analysis to assess the potential impact on ECL from housing market volatility. The impact is driven by marginal growth in the housing market with subdued demand for purchases driven by the increases interest rates.

**Measuring ECL** (audited)

For accounts not in default at the reporting date, we estimate a monthly ECL for each exposure and for each month over the forecast period. The lifetime ECL is the sum of the monthly ECLs over the forecast period, while the 12-month ECL is limited to the first 12 months. We calculate each monthly ECL as the discounted value for the relevant forecast month of the product of the following factors:

---

| | |
|:---|:---|
| Factor | Description |
| **Survival rate (SR)** | The probability that the exposure has not closed or defaulted since the reporting date. |
| **Probability of default (PD)** | The likelihood of a borrower defaulting in the following month, assuming it has not closed or defaulted since the reporting date. For each month in the forecast period, we estimate the monthly PD from a range of factors. These include the current risk grade for the exposure, which becomes less relevant further into the forecast period, as well as the expected evolution of the account risk with maturity and factors for changing economics. We support this with historical data analysis. |
| **Exposure at default (EAD)** | The amount we expect to be owed if a default event occurs. We determine EAD for each month of the forecast period by the expected payment profile, which varies by product. For amortising products, we base it on the borrower's contractual repayments over the forecast period. We adjust this for any expected overpayments on Stage 1 accounts that the borrower may make and for any arrears we expect if the account was to default. For revolving products, or amortising products with an off-balance sheet element, we determine EAD using the balance at default and the contractual exposure limit. We vary these assumptions by product and base them on analysis of recent default data. |
| **Loss given default (LGD)** | Our expected loss if a default event were to occur. We express it as a percentage and calculate it based on factors that we have observed to affect the likelihood and/or value of any subsequent write-offs, which vary according to whether the product is secured or unsecured. If the product is secured, we take into account collateral values as well as the historical discounts to market/book values due to forced sales type. |

---

We use the original effective interest rate as the discount rate. For accounts in default, we use the EAD as the reporting date balance. We also calculate an LGD to reflect the default status of the account, considering the current DPD and loan to value. PD and SR are not required for accounts in default.

**Forecast period**

We base the forecast period for amortising facilities on the remaining contract term. For revolving facilities, we base it on the behavioural, rather than contractual, characteristics of the facility type. In some cases, we shorten the period to simplify the calculation. If we do this, we apply a Judgemental Adjustment to reflect our view of the full lifetime ECL.

**Forward-looking information** 

Our assessments of a SICR and the calculation of ECL incorporate forward-looking data. We perform historical analysis and identify the key economic variables that impact credit risk and ECL for each portfolio. These can include house price growth, GDP, unemployment rate and BoE Bank Rate. Where applicable, we incorporate these economic variables and their associated impacts into our models.

Economic forecasts have the most impact on ECL measurement for residential mortgages and, to a lesser extent, corporate loans. This is due to the long behavioural lives and large size of these portfolios. Economic forecasts have less impact on ECL for other portfolios due to their shorter lives and smaller size.

**Grouping of instruments for losses measured on a collective basis** 

We measure ECL at the individual financial instrument level. However, where we have used internal capital or similar models as the basis for our ECL models, this typically results in a large number of relatively small homogenous groups. We typically group instruments where they share risk characteristics using statistical models and assess them for impairment collectively.

We use this approach for

–all our Retail Banking and Consumer Finance portfolios,

–SME customers in Corporate & Commercial Banking, and

–Legacy Portfolios in run-off in Corporate Centre.

We calculate separate collective provisions for instruments in Stages 1, 2 and 3 where the instrument is not individually assessed.

For all our portfolios (whether we assess them for impairment individually or collectively) we use five forward-looking economic scenarios.

**Governance around ECL impairment allowances** (audited)

Our Risk Methodology team developed our ECL models (except for the external models we use, such as OGEM which we described earlier in 'Our forecasting approach'), and our Independent Validations team reviews all material models. As model owners, our Risk Provisioning & Forecasting team run the models to calculate our ECL each month. The models are sensitive to changes in credit conditions and reflect management judgements that give rise to measurement uncertainty in our ECL as set out above. The following committees and forums review the provision drivers and ensure that the ECL remains appropriate:

**–Model Risk Control Forum** (MRCF) reviews and approves new models and model changes. It also reviews the use of OGEM as a reliable model on which to base our other forecast macroeconomic variables. We use it across all stress testing and planning so it is subject to model risk criteria.

**–ALCO** reviews and approves the base case used in the economic scenarios we use to calculate forward-looking scenarios.

**–CRPF** reviews and approves the economic scenarios and probability weights we use to calculate forward-looking scenarios. It also reviews management judgements and approves ECL impairment allowances.

**–Board Audit Committee** reviews and challenges the appropriateness of the estimates and judgements made by management.

For more on the governance around specific elements of the ECL impairment allowances, including the frequency of, and thresholds for, reviews, including by these committees and forums, see the detailed sections above.

**How we assess the performance of our ECL estimation process**

We assess the reasonableness of our ECL provisions and the results of our Staging analysis using a range of methods. These include:

**–Benchmarking:** we compare our coverage levels with our peers.

**–Stand-back testing:** we monitor the level of our coverage against actual write-offs.

**–Back-testing:** we compare key drivers periodically as part of model monitoring practices.

**–Monitoring trends:** we track ECL and Staged assets over time and against our internal budgets and forecasts, with triggers set accordingly.

SANTANDER UK GROUP LEVEL – CREDIT RISK REVIEW

**Our maximum and net exposure to credit risk** (audited)

The tables below show the main differences between our maximum and net exposure to credit risk. They show the effects of collateral, netting, and risk transfer to mitigate our exposure. The tables only show the financial assets that credit risk affects and to which the impairment requirements in IFRS 9 are applied.

For balance sheet assets, the maximum exposure to credit risk is the carrying value after impairment loss allowances. Off-balance sheet exposures are mortgage offers, guarantees, formal standby facilities, credit lines and other commitments. For off-balance sheet guarantees, the maximum exposure is the maximum amount that we would have to pay if the guarantees were called on. For formal standby facilities, credit lines and other commitments that are irrevocable over the life of the facility, the maximum exposure is the total amount of the commitment.

(1)The forms of collateral we take to reduce credit risk include: residential and commercial property; other physical assets, including motor vehicles; liquid securities, including those transferred under reverse repurchase agreements; cash, including cash used as collateral for derivative transactions; and receivables. Charges on residential property are most of the collateral we take.

(2)We can reduce credit risk exposures by applying netting. We do this mainly for derivative and repurchase transactions with financial institutions. For derivatives and securities finance transactions, we use standard master netting agreements. For more on this, see 'Credit risk mitigation' in the 'Credit risk - Credit risk management' section.

(3)Balances include interest we have charged to the customer's account and accrued interest that we have not charged to the account yet.

(4)The collateral value shown against advances secured on residential property is limited to the balance of each associated individual loan. It does not include the impact of over–collateralisation (where the collateral has a higher value than the loan balance) and includes collateral we would receive on draw down of certain off–balance sheet commitments.

(1)The forms of collateral we take to reduce credit risk include: liquid securities, including those transferred under reverse repurchase agreements; cash, including cash used as collateral for derivative transactions; and receivables.

(2)We can reduce credit risk exposures by applying netting. We do this mainly for derivative and repurchase transactions with financial institutions. For derivatives and securities finance transactions, we use standard master netting agreements. They allow us to set off our credit risk exposure to a counterparty against our obligations to the counterparty in relation to transactions under the master netting agreement in the event of default. This gives us a lower net credit exposure. They may also reduce settlement exposure. For more on this, see 'Credit risk mitigation' in the 'Credit risk – Credit risk management' section.

**Single credit rating scale** 

In the table below, we have used a single rating scale to ensure we are consistent across all our credit risk portfolios in how we report the risk of default. It has eight grades for non–defaulted exposures, from 9 (lowest risk) to 2 (highest risk). We define each grade by an upper and lower PD value and we scale the grades so that the default risk increases by a factor of ten every time the grade number drops by two steps. For example, grade 9 has an average PD of 0.010%, and grade 7 has an average PD of 0.100%. We give defaulted exposures a grade 1 and a PD value of 100%. In the final column of the table we show the approximate equivalent credit rating grade used by Standard & Poor's Ratings Services (S&P).

|:---|:---|:---|:---|:---|
| | PD range | PD range | PD range | |
| | Mid | Lower | Upper | S&P equivalent |
| Santander UK risk grade | % | % | % | S&P equivalent |
| 9 | 0.010 | 0.000 | 0.021 | AAA to AA+ |
| 8 | 0.032 | 0.021 | 0.066 | AA to AA- |
| 7 | 0.100 | 0.066 | 0.208 | A+ to BBB |
| 6 | 0.316 | 0.208 | 0.658 | BBB- to BB |
| 5 | 1.000 | 0.658 | 2.081 | BB- |
| 4 | 3.162 | 2.081 | 6.581 | B+ to B |
| 3 | 10.000 | 6.581 | 20.811 | B- |
| 2 | 31.623 | 20.811 | 99.999 | CCC to C |
| 1 (Default) | 100.000 | 100.000 | 100.000 | D |

The PDs in the table above are based on Economic Capital (EC) PD mappings, calculated based on the average PD over an economic cycle. This is different to the IFRS 9 PDs which are calculated at a point in time using forward looking economic scenarios. Where possible, the EC PD values are aligned to the regulatory capital models however any regulatory floors are removed and PDs are defined at every possible rating rather than grouped into rating buckets.

2022 compared to 2021

The ECL provision at 31 December 2022 increased by £140m to £1.0bn (2021: £0.9bn). Notable changes to ECL in 2022 which impacted credit impairment were:

–**Corporate Covid-19 related JAs:**: net release of £175m. All corporate sector staging JAs related to Covid-19 released, resulting in £0.4bn movement of corporate Stage 3 loans to Stage 2.

–**Economic scenarios and weights**: charge of £163m. Updated economic scenarios with expectations for higher base rate and lower house prices in 2023

–**Corporate sector staging risks**: charge of £61m. JAs to reflect the corporate lending risks for sectors and counterparties which are most susceptible to increased inflation, energy prices and input costs alongside potentially lower demand. As a result, £1.4bn of higher risk Stage 1 loans were moved to Stage 2, and probability of defaults increased on some Stage 2 loans following an assessment of the client and sector risks.

**–Affordability of retail lending repayments**: charge of £44m. JAs to account for the potential repayment affordability risk among those customers with low disposable income. After stressing for inflation, £0.2bn of unsecured loans, overdrafts and credit cards moved from Stage 1 to Stage 2. In addition, £5.0bn of mortgages moved from Stage 1 to Stage 2 following an assessment of customer indebtedness.

**–Write-offs against provision**: Gross write-off utilisation of £157m (2021: £191m).

Key movements in exposures and ECL in the period by Stage were:

–The reduction in Stage 1 exposures arose mainly from changes in Corporate Centre. This reduction was partially offset by the growth in the mortgage portfolio and Corporate & Commercial Banking. The Stage 1 ECL increased mainly due to the increase in Corporate & Commercial Banking as a result of unwinding the Corporate lending to segments affected by Covid-19 JA that placed more vulnerable accounts into Stage 2.

–Total Stage 2 exposures increased due to the implementation of cost of living JAs to cover the affordability risk associated with the increase in interest rates and energy pries. This included a portion of the mortgage and unsecured lending portfolios from Stage 1 to Stage 2. This was partially offset by the unwinding of the Corporate lending to segments affected by Covid-19 JAs. In Retail Banking, Stage 2 exposures increased due to the implementation of cost of living JAs to cover the affordability risk associated with the increase in interest rates and energy prices. Stage 2 ECL increased due to a worsening in the economic outlook with the inclusion of an inflationary pressure scenario. Retail Banking Stage 2 ECL also increased due to affordability risk JAs.

–Stage 3 exposures and ECL reduced due to releasing the Stage 2-3 Corporate lending to segments affected by Covid-19 JAs. Stage 3 exposures and ECL remained fairly stable across the Retail Banking portfolio.

2022 compared to 2021

The accounts in a cure period increased in 2022 due to the introduction of the Unsecured Affordability JA and an increase in the number of accounts falling in scope for the Mortgage affordability JA. Accounts which have been moved into Stage 2 due to a JA are assumed to not be in a cure period.

2022 compared to 2021

Following the implementation of a new regulatory definition of default in early 2022, we introduced a cure period criteria for Stage 3 assets. We did not have any cure period criteria for Stage 3 at 31 December 2021 and as the change in definition was a change in estimate the prior periods were not amended.

The table below shows the relationships between disclosures in this Credit risk review section which refer to drawn exposures and the associated ECL, and the total assets as presented in the Consolidated Balance Sheet. The Credit risk review disclosures exclude Joint ventures, as they carry low credit risk and therefore have an immaterial ECL, and Other items, mainly accrued interest that we have not yet charged to the customer's account, and cash collateral.

(1)Exposures that have attracted an ECL, and as reported in the Credit Quality table above.

(2)Changes to assumptions in the period. Isolates the impact on ECL from changes to the economic variables for each scenario, the scenarios themselves, and the probability weights from all other movements. Also includes the impact of quarterly revaluation of collateral. The impact of changes in economics on exposure Stage allocations are shown in Transfers of financial instruments.

(3)Total impact of facilities that moved Stage(s) in the period. This means, for example, that where risk parameter changes (model inputs) or model changes (methodology) result in a facility moving Stage, the full impact is reflected here (rather than in Other). Stage flow analysis only applies to facilities that existed at both the start and end of the period. Transfers between Stages are based on opening balances and ECL at the start of the period.

(4)Relates to the revaluation of ECL following the transfer of an exposure from one Stage to another.

(5)Exposures and ECL of facilities that did not exist at the start of the period but did at the end. Amounts in Stage 2 and 3 represent assets which deteriorated in the period after origination in Stage 1.

(6)Residual movements on existing facilities that did not change Stage in the period, and which were not acquired in the period. Includes the net increase or decrease in the period of cash at central banks, the impact of changes in risk parameters in the period, unwind of discount rates and increases in ECL requirements of accounts which ultimately were written off in the period.

(7)Exposures and ECL for facilities that existed at the start of the period but not at the end.

COUNTRY RISK EXPOSURES (AUDITED)

We manage our country risk exposure under our global limits framework. We set our Risk Appetite for each country, taking into account factors that may affect its risk profile. These can include political events, macroeconomics and the nature of the risk. We actively manage exposures if we need to.

The tables below show our total exposures, which are the total of balance sheet and off–balance sheet values. We calculate balance sheet values in line with IFRS (i.e. after netting allowed under IAS 32) except for credit provisions which we add back. Off–balance sheet values are undrawn facilities and letters of credit. We classify location by country of risk – the country where each client has its main business or assets. That is unless there is a full risk transfer guarantee in place. If so, we use the guarantor's country of domicile. If a client has operations in many countries, we use their country of incorporation. The table below excludes balances with other Banco Santander group members. We show them separately in the section that immediately follows.

**Balances with other Banco Santander group members** (audited)

We deal with other Banco Santander group members in the ordinary course of business. We do this where we have a particular business advantage or expertise and where they can offer us commercial opportunities. These transactions also arise where we support the activities of, or with, larger multinational corporate clients and financial institutions which may deal with other Banco Santander group members. We conduct these activities on the same terms as for similar transactions with third parties, and in a way that manages the credit risk within limits acceptable to the Board and the PRA.

At 31 December 2022 and 31 December 2021, we had gross balances with other Banco Santander group members as follows:

(1)'Home movers' include both existing customers moving house and taking out a new mortgage with us, and customers who switch their mortgage to us when they move house.

(2)'Remortgagers' are new customers who are taking a new mortgage with us

As well as the new business above, there were £24.9bn (2021: £29.8bn) of remortgages where we moved customers with maturing products onto new mortgages. We also provided £1.2bn (2021: £1.4bn) of further advances and flexible mortgage drawdowns. 81% (2021: 83%) of customers with a maturing mortgage were retained, which applied to mortgages four months post maturity and calculated as a 12-month average of retention rates to September.

2022 compared to 2021

In 2022, mortgage asset stock increased across all sectors, with the stock borrower profile unchanged. Our new business increased, mainly in remortgages, reflecting market conditions and strong demand from first time buyers, driven by customers securing fixed rate products in a rising interest rate environment. In 2022, we helped first-time buyers buy their new home with £8.1bn of gross lending (2021: £6.2bn).

**Interest rate profile** (audited)

The interest rate profile of our maturing mortgage asset stock was:

|  | **184317** | **100** | 174712 | 100 |

---

2022 compared to 2021

In 2022 , we continued to see customers refinance from variable rate and SVR to fixed rate products influenced by the rapid increases in interest rates and the competitive mortgage market. Within fixed rate products, we continued to see an increase in the proportion of 5 year fixed rate mortgages in 2022.

**Geographical distribution** (audited)

The geographical distribution of our mortgage asset stock and new business was:

2022 compared to 2021

The portfolio's geographical distribution continued to represent a broad footprint across the UK, with a concentration around London and the South East. The loan-to-income multiple of mortgage lending in the year, based on average earnings of new business at inception, was 3.35 (2021: 3.35).

(1)Collateral value is limited to the balance of each loan and excludes the impact of any over-collateralisation. Includes collateral against loans in negative equity of £323m (2021: £455m).

(2)Balance weighted LTV = (Loan 1 balance x (Loan 1 Balance/Loan 1 latest property valuation) + (Loan 2 balance x (loan 2 balance/Loan 2 latest property valuation)+ ...) /(Loan 1 balance + Loan 2 balance+...).

(3)Simple average stock LTV 39% (2021: 41%).

At 31 December 2022, the parts of loans in negative equity which were effectively uncollateralised before deducting loss allowances was £48m (2021: £75m). The balance weighted average LTV of new business in the period in London was 66% (2021: 64%).

31 December 2022 compared to 31 December 2021

There were no significant changes in collateral quality in 2022. Despite economic pressures, balance weighted average LTVs were broadly flat over the period. We monitor the LTV profile of new lending and take action as needed to ensure the LTV mix of completions is appropriate.

(1)We base forbearance type on the first forbearance on the accounts.

2022 compared to 2021

In 2022, forbearance activity was stable. The proportion of the mortgage portfolio in forbearance remained flat at 0.9% (2021: 0.9%).

–At 2022, the proportion of accounts in forbearance for more than six months that had made their last six months' contractual payments was 85% (2021: 85%).

–The weighted average LTV of all accounts in forbearance was 43% (2021: 32%) compared to the weighted average portfolio LTV of 50% (2021: 35%)

–At 2022, the carrying value of mortgages classified as multiple forbearance increased slightly to £152m (2021: £148m).

**Other loan modifications**

From March 2020 to March 2021, we provided mortgage customers with payment holiday terms in line with UK Government and FCA guidance. The scheme has now ceased. The following table provides information on such loan modifications.

---

At 2022, there were £1.9bn (2021: £2.3bn) of other mortgages on the balance sheet that we had modified since January 2008. At 2022:

–The average LTV was 24% (2021: 27%), and 94% (2021: 95%) of accounts had made their last six months' contractual payments.

–The proportion of accounts that were 90 days or more in arrears was 1.53% (2021: 2.62%).

There were no other loan modifications made in the year.

RETAIL BANKING: HOMES – PORTFOLIOS OF PARTICULAR INTEREST

**Introduction** 

We are mainly a residential prime lender and we do not originate sub-prime or second charge mortgages. Despite that, some types of mortgages have higher risks and others stand out for different reasons. These are:

---

| | |
|:---|:---|
| Product | Description |
| **Interest-only loans and part interest-only, part repayment loans** | With an interest-only mortgage, the customer pays interest every month but the principal is only repaid at the end of the mortgage term. Some mortgages have a part that is interest-only, with the rest being a normal repayment mortgage. Customers with part interest-only, part repayment mortgages still have to pay back a lump sum at the end of their mortgage for the interest-only part. This means these loans have a higher credit risk as we depend on the customers to pay back a lump sum. We design new account LTV maximums to mitigate this risk. We also make sure the customer has a plausible repayment plan before we lend to them and stays on track for the loan term.<br>We mitigate the risk from new interest-only mortgages by having lower maximum LTVs. For most applicants, the maximum LTV is 50%. For high net worth customers, it can be up to 75%. When a customer plans to repay their mortgage by selling the property, we require a minimum equity buffer of £250k. We also remind customers that they have to arrange to repay the principal at the end of the mortgage. We send them messages with their annual mortgage statements, and we contact them throughout the mortgage term to encourage them to tell us how they plan to repay. We increase the frequency of contact as the loan approaches maturity. If customers know they will not be able to repay their mortgage when it ends, or if their mortgage has already passed the date when it should have ended, we talk to them. If we think it is in their interests and they can afford it, we look at other ways to manage it, such as turning the mortgage into a repayment one and extending it. If the customer is waiting for their way to repay it, such as an investment plan, to mature, we may permit an extension. |
| **Flexible loans** | Flexible mortgages allow customers to pay more or less than their usual amount each month, or even to take 'payment holidays' when they pay nothing at all. There are conditions on when and how much customers can draw down, and they do not have to take or draw down the whole loan all at once. A customer can ask us to raise their credit limit, but that means we will go through our full credit approval process. We can also lower a customer's credit limit at any time, so it never goes above 90% of the property's current market value. We no longer offer flexible loans for new mortgages. This is an area of interest if any customers might be using these facilities to self-forbear, such as regularly drawing down small amounts. We reflect signs that the credit risk has significantly increased in our ECL calculations. |
| **Loans with an LTV >100%** | In some cases, property prices have fallen, so mortgages we gave in the past with lower LTVs now have LTVs greater than 100%. Where the mortgage balance is more than the property is now worth, we cannot recover the full value of the loan by repossessing and selling the property. This means there is a higher credit risk on these loans so we monitor them as part of our assessment of ongoing portfolio performance. We design new account LTV maximums to mitigate an increase in accounts with an LTV >100%.  |
| **Buy-to-Let (BTL) loans** | We have specific policies for BTL and focus on non-professional landlords. We have prudent lending criteria and the maximum LTV is 75%. The first applicant must earn a minimum of £25,000 per year, and we require proof of income in all cases. We also use a BTL affordability rate as part of our lending assessment. This means that the rental income must cover the monthly mortgage interest payments by a prescribed amount when calculated using a stressed interest rate. We regularly review the prescribed amount and adjust it as needed. |

---

**Climate change**

The value of property collateral for mortgages might be affected by physical impacts related to the frequency and scale of extreme weather events, such as flood and subsidence risk or changing environmental performance standards for property. In 2022 we reviewed the proportion of mortgage loans subject to flood and subsidence risk and concluded that the risk was not material. The terms of our mortgage lending require homeowners to buy suitable insurance which transfers the majority of the risk to asset valuations to third party insurers.

(1)Where a loan falls into more than one category, we include it in all the categories that apply. As a result, the sum of the mortgages in the segments of particular interest and the other portfolio does not agree to the total mortgage portfolio.

(2)Mortgage balance includes both the interest-only part of £10,010m (2021: £10,106m) and the non-interest-only part of the loan.

2022 compared to 2021

–In 2022, the combined total proportion of interest-only loans, part interest-only, part repayment loans and flexible loans remained stable.

–BTL mortgage balances increased £1.9bn to £16.8bn (2021: £14.9bn) driven by continued focus in growing this portfolio. In 2022, the balance weighted average LTV of mortgage total new BTL lending was 67% (2021: 68%)

(1)Where a loan falls into more than one category, we have included it in all the categories that apply.

(2)Comprises full interest-only loans and part interest-only, part repayment loans.

2022 compared to 2021

Levels of forbearance on interest-only accounts decreased in 2022. The higher levels of forbearance on interest-only accounts in 2021 were driven by the availability of a one year deferral of repaying capital for maturing or past maturity interest-only customers impacted or potentially impacted by Covid-19. This was offered in line with FCA guidance. The scheme closed in 2021.

(1)The ECL allowance is for both on and off–balance sheet exposures

2022 compared to 2021

Business Banking balances were lower, mainly due to reductions in the Bounce back loans (BBL) portfolio. Stage 3 assets reduced, although this had a minimal impact on write offs as the reduction in assets was mainly due to the BBLs, where the 100% government guarantee was claimed. Other unsecured balances increased slightly in 2022. However, Stage 2 unsecured assets increased by125%, reflecting the current economic environment. This is yet to impact Stage 3 or write offs, which did not increase.

**Loan modifications**

The following table (audited) sets out the financial assets that were forborne while they had a loss allowance measured at lifetime ECL.

(1)The ECL allowance is for both on and off–balance sheet exposures.

2022 compared to 2021

In 2022, we maintained our prudent Consumer (auto) finance underwriting criteria. The product mix was broadly unchanged, with wholesale balances increasing slightly.

At 31 December 2022, Consumer (auto) finance gross lending (new business) was £2,519m(2021: £2,383m). Wholesale loans (Stock finance) to car dealerships at 31 December 2022 were approximately 10.1% (2021: 7.3%) of the Consumer loan book. At 31 December 2022, the average Consumer (auto) finance loan size was £17,256 (2021: £16,182).

The risk profile was stable in terms of our credit scoring acceptance policies. The overall risk performance was good with the vast majority of customers paying.

**Loan modifications**

**Forbearance**

There were no accounts in forbearance at 31 December 2022 and 31 December 2021.

**Other loan modifications**

From March 2020 to March 2021, we provided Consumer Finance customers with payment holiday terms. The following table provides information on such loan modifications.

**Committed exposures**

Credit risk arises on both on- and off–balance sheet transactions, e.g. guarantees. Therefore, committed exposures are typically higher than asset balances. However, committed exposures can be smaller than asset balances due to netting.

**Rating distribution** (audited)

These tables show our credit risk exposure according to our internal rating scale (see 'Credit quality' in the 'Santander UK group level – credit risk review' section) for each portfolio. On this scale, the higher the rating, the better the quality of the counterparty.

(1)Smaller exposures mainly in the commercial mortgage portfolio. We use scorecards for them, instead of a rating model.

2022 compared to 2021

In 2022, committed exposure was substantially unchanged, with an increase in the CRE portfolio of 12%, largely offset by reductions in SME and mid corporate. The rating distribution improved in the CRE portfolios following recovery in the credit quality of a number of customers initially downgraded as a result of Covid-19. It has remained broadly stable in SME and mid corporate.

**Geographical distribution** (audited)

We typically classify geographical location according to the counterparty's country of domicile unless a full risk transfer guarantee is in place, in which case we use the guarantor's country of domicile instead.

(1)&nbsp;&nbsp;&nbsp;&nbsp;Includes committed facilities and derivatives.

(2)New customer management systems have introduced improved portfolio segmentation information. This has led to a realignment of portfolio segmentation and improved the identification of portfolios of particular interest. Due to this a restatement of the 2021 figures has taken place.

2022 compared to 2021

Across Corporate & Commercial Banking, watchlist exposure decreased, enhanced monitoring by 20% and proactive monitoring by 26% This followed the upgrading of cases as they stabilised after emerging from Covid-19 lockdowns especially in SME and Mid Corporates whilst CRE saw an increase in Proactive Management.

Stage 3 assets also decreased, down 31% with loss allowances decreasing by £31m (7%). The remaining Covid-19 related judgemental adjustments (JAs) were released. New JAs have been introduced to reflect the heightened risks of sectors and counterparties deemed most susceptible to current headwinds.

(1)We base forbearance type on the first forbearance we applied. Tables only show accounts open at the period-end. Amounts are drawn balances and include off balance sheet balances.

2022 compared to 2021

In 2022, forbearance stock decreased overall due to a single case that was first reported as forbearance in 2021, and was repaid in 2022. This was partially offset by a small increase in other cases.

PORTFOLIOS OF PARTICULAR INTEREST

**Introduction**

Some types of lending have higher risk and others stand out for other reasons. We give more detail below on the following areas of particular interest.

---

| | |
|:---|:---|
| Portfolio | Description |
| **Commercial Real Estate (CRE)** | Lending to experienced, professional landlords mainly secured by tenanted UK property. The CRE market has seen regular cyclical downturns, and so is a portfolio of particular interest. We manage and report our CRE portfolio in Corporate & Commercial Banking. |

---

**In prior periods, we also gave a summary of our total Social Housing portfolio as we managed part of it in Corporate & Commercial Banking and part of it in Corporate Centre. With effect from 2022, we manage all our Social Housing portfolio in Corporate & Commercial Banking, as explained in Note 2 to the Consolidated Financial Statements. As a result, information on our total Social Housing portfolio is now presented in the main Corporate & Commercial Banking section.**

**Climate change**

The global economy is still heavily dependent on fossil fuel energy sources such as coal, natural gas and oil, which significantly contribute to climate change. Energy transmission requires building and maintaining appropriate wholesale networks that can affect the natural environment. We remain committed to reallocating financial flows from fossil fuel consumption, including for electricity generation, to cleaner alternatives as set out in our Environmental, Social and Climate Change Policy.

In order to track and measure how our current lending activities contribute towards the reliance of fossil fuels, in 2022 we analysed our portfolio to identify fossil fuel exposures. We classified lending as a fossil fuel exposure if the counterparty engaged in any of the following activities:

**–Oil & Gas: production and treatment including refining, transportation, storage and wholesale distribution**

**–Mining & Extraction: any coal mining or extraction activities**

–Power Generation: clients for who coal-fired generation represents more than 10% of revenues on a consolidated basis.

At 31 December 2022, we had limited exposure to such counterparties, with these activities making up 0.4% of our Corporate and Commercial Banking lending to non-financial corporates. On an individually assessed basis, clients in these industries were highly rated and their markets remained highly liquid. We will continue to monitor, disclose and reduce lending which contributes to ongoing fossil fuel **use.**

**Refinancing risk**

At 31 December 2022, CRE loans of £964m (2021: £1,084m) were due to mature within 12 months. Of these, £17m or 1.8% (2021: £7m or 0.7%) had an LTV ratio higher than is acceptable under our current credit policy, £7m of which were reported as Stage 3 (2021: £4m).

1)&nbsp;&nbsp;&nbsp;&nbsp;Mainly commercial mortgages.

2022 compared to 2021

The CRE portfolio is well diversified across sectors with no significant regional or single name concentration. In 2022, the market faced falling capital and rental yields along with structural changes in certain sub-sectors such as Retail and Office. However at 31 December 2022, the LTV profile of the portfolio remained conservative with £4,234m and 95% (2021: £3,679m and 98%) at or below 70% LTV. Almost two thirds of the CRE portfolio has an LTV below 50%.

Drawn customer loans increased by £477m. In 2022 , we maintained a prudent lending approach, with >99% of new business (2021: 100%) written at or below 60% LTV. The weighted average LTV of the CRE portfolio was 46%.

Drawn facilities subject to enhanced monitoring decreased by 48% to £102m (2021: £198m). Drawn facilities subject to proactive management increased by 115% to £473m (2021: £220m). Stage 3 exposures decreased to £58m (2021: £79m).

(1)Smaller exposures mainly in the commercial mortgage portfolio. We use scorecards for them, instead of a rating model.

(2)Commercial mortgages and residual structured and asset finance loans (shipping, aviation and structured finance).

2022 compared to 2021

Committed exposures decreased by 11.2% mainly driven by UK Sovereign and Supranational exposures, as part of normal liquid asset portfolio management, which reduced by 14.2%. The portfolio profile remained short-term, reflecting the purpose of the holdings.

**Geographical distribution** (audited)

We typically classify geographical location according to the counterparty's country of domicile unless a full risk transfer guarantee is in place, in which case we use the guarantor's country of domicile instead.

Market risk

---

| | |
|:---|:---|
| Overview <br>Market risk comprises non-traded market risk and traded market risk. <br>Non-traded market risk is the risk of loss of income, economic or market value due to changes to interest rates in the non-trading book or to changes in other market risk factors (e.g. credit spread and inflation risk), where such changes would affect our net worth through an adjustment to revenues, assets, liabilities and off-balance sheet exposures in the non-trading book. <br>Traded market risk is the risk of changes in market factors that affect the value of the positions in the trading book. We have no significant traded market risk exposure.<br>In this section, we set out which of our assets and liabilities are exposed to non-traded and traded market risk. Then we explain how we manage these risks and discuss our key market risk metrics. | **Key metrics** <br>Net Interest Income (NII) sensitivity to +100bps was £241m and to -100bps was £(197)m (2021: £318m and £(440)m).<br>Economic Value of Equity (EVE) sensitivity to +100bps was £(487)m and to -100bps was £635m (2021: £(431)m and £184m). |

---

BALANCE SHEET ALLOCATION BY MARKET RISK CLASSIFICATION (AUDITED)

We classify all our assets and liabilities exposed to market risk as non-traded market risk, except for certain portfolios that we must classify as trading books for regulatory purposes (such as selling derivatives or derivative-based products to clients), of which we must fair value for accounting reasons (such as assets in the eligible liquidity pool). For accounting purposes, we classify all derivatives as held for trading unless they are designated as being in a hedging relationship. For more, see Note 11 to the Consolidated Financial Statements.

NON-TRADED MARKET RISK

OUR KEY NON-TRADED MARKET RISKS (audited)

Non-traded market risk mainly comes from providing banking products and services to our customers, as well as our structural balance sheet exposures. It arises in all our business segments. In Retail Banking, Consumer Finance and Corporate & Commercial Banking, it is a by-product of us writing customer business and we transfer most of these risks to Corporate Centre to manage. The only types of non-traded market risk that we keep in Retail Banking, Consumer Finance and Corporate & Commercial Banking are short-term mismatches due to forecasting variances in prepayment and launch risk. This is where customers repay their loans earlier than their expected maturity date or do not take the expected volume of new products. Corporate Centre also manages our structural balance sheet exposures, such as foreign exchange and Income Statement volatility risk.

Our key non-traded market risks are:

---

| | |
|:---|:---|
| Key risks | Description |
| **Interest rate risk** | **Yield curve risk:** comes from timing mismatches in repricing fixed and variable rate assets, liabilities and off-balance sheet instruments. It also comes from investing non-rate sensitive liabilities in interest-earning assets. <br>**Basis risk:** comes from pricing assets using a different rate index to the liabilities that fund them. We are exposed to basis risks associated with Bank of England bank rate, reserve rate linked assets we deposit with central banks, and the Sterling Overnight Index Average (SONIA) rate. |
| **Spread risk** | Spread risk arises when the value of assets or liabilities which are accounted for at fair value (either through Other Comprehensive Income or through Profit and Loss) are affected by changes in the credit spread. We measure these spreads as the difference between the discount rate we use to value the asset or liability, and an underlying interest rate curve. |
| **Foreign exchange risk** | Our banking businesses operate mainly in sterling markets, so we do not create significant foreign exchange exposures. The only exception to this is money we raise in foreign currencies. For more on this, see 'Wholesale funding' in the 'Liquidity risk' section. |
| **Income statement<br>volatility risk** | We measure most of the assets and liabilities in our banking book balance sheet at amortised cost. We sometimes manage their risk profile by using derivatives. As all derivatives are accounted for at fair value, the mismatch in their accounting treatment can lead to volatility in our Income Statement. This happens even if the derivative is an economic hedge of the asset or liability. |

NON-TRADED MARKET RISK MANAGEMENT

**Risk appetite**

Our Structural and Market Risk framework sets out our high-level arrangements and standards to manage, control and oversee non-traded market risk, and is part of our overall Risk Framework. Our Risk Appetite sets the controls, risk limits and key risk metrics for non-traded market risk. We show risk appetite by the income and value sensitivity limits we set in our Risk Appetite, at both Santander UK and Banco Santander group levels.

**Risk measurement** 

We mainly measure our exposures with NII and EVE sensitivity analysis. We support this with VaR risk measures and stress testing. We also monitor our interest rate repricing gap. We regularly review our risk models and metrics including underlying model assumptions to ensure they continue to reflect the risks inherent in the current rate environment and regulatory expectations.

**NII and EVE sensitivities** (audited)

The calculations for NII and EVE sensitivities involve many assumptions, including expected customer behaviour (such as early repayment of loans) and how interest rates may move. These assumptions are a key part of our overall control framework, so we update and review them regularly. Our NII and EVE sensitivities include the interest rate risk from all our banking book positions. Our banking book positions generate almost all our reported net interest income.

---

| |
|:---|
| NII sensitivity |
| NII sensitivity is an income-based measure we use to forecast the changes to interest income and interest expense in different scenarios. It gives us a combined impact on net interest income over a given period – usually 12 or 36 months. |
| We calculate NII sensitivity by simulating the NII using 2 yield curves. The difference between the 2 NII totals is the NII sensitivity. |

---

EVE sensitivity <br> –We calculate EVE sensitivity as the change in the net present value of all the interest rate sensitive items in the banking book balance sheet for a defined set of instantaneous parallel and non-parallel shifts in the yield curve.

The limitations of sensitivities

We use sensitivities to measure the impact of standard, instantaneous, parallel shifts in relevant yield curves. The advantage of using standard parallel shifts is they generally give us a constant measure of the size of our market risk exposure, with a simple and consistent stress. We also run non-parallel stress tests, to calculate the impact of some plausible non-parallel scenarios, and over various time periods for income stresses, usually one or three years.

**Value at Risk (VaR)** (audited)

---

| |
|:---|
| VaR |
| –VaR indicates the losses that we might suffer because of unfavourable changes in the markets under normal (non-stressed) market conditions. |
| &nbsp;&nbsp;&nbsp;We run a historical simulation using historical daily price moves to find how much we might lose, normally at a 99% confidence level. |

---

The limitations of VaR

VaR is a useful and important market standard measure of risk, but it does have some limitations. These include:

–VaR assumes what happened in the past is a reliable way to predict what will happen in the future. This may not always be the case

–VaR is based on positions at the end of the business day so it doesn't include intra-day positions

–VaR does not predict how big the loss could be on the 1% of trading days that it is greater than the VaR

–Using a time horizon of one day means VaR does not tell us everything about exposures that we cannot liquidate or hedge within a day, or products with infrequent pricing.

Back-testing – comparing VaR estimates with reality

To check that the way we estimate VaR is reasonable, we back-test our VaR by comparing it against both actual and hypothetical profits and losses, using a one-day time horizon. Back-testing allows us to identify exceptions – times when the predictions were out of line with what happened. We can then look for trends in these exceptions, which can help us decide whether we need to recalibrate our VaR model.

**Stress testing** 

Stress testing is an essential part of our risk management. It helps us to measure and evaluate the potential impact on portfolio values of more extreme, although plausible, events or market moves. We express limits as on how much we could lose in a stress event, and this restricts how much risk we take.

Stress testing scenarios

Simple stress tests (like parallel shifts in relevant curves) give us clear measures of risk and a consistent starting point for setting limits. More complex, multi-factor and multi-time period stress tests give us information about specific potential events. They can also test outcomes that we might not capture through parallel stresses or VaR-type measures. We use stress tests to estimate losses in extreme market events beyond the confidence level used in VaR models.

We can adapt our stress tests to reflect current concerns such as climate change risk, the Covid-19 pandemic and other macroeconomic events or changing market conditions. We run individual business area stresses and Santander UK-wide scenarios.

**Other ways of measuring risk**

As well as using sensitivities and stress tests, we can measure non-traded market risk using net notional positions. This can give us a simple view of our exposure, although we generally need to combine it with other risk measures to cover all aspects of a risk profile, such as projected changes over time. Other metrics we can use include Earnings at Risk (EaR). EaR is like VaR but captures changes in income rather than value. We use this approach for example to generate a one-year EaR measure to assess Basis risk.

**Risk mitigation** (audited)

We typically hedge the interest rate risk of the securities we hold for liquidity and investment purposes with interest rate swaps. We retain spread exposures, and these are the key drivers of the VaR and stress tests we use to assess the risk of the portfolio. We mitigate Income Statement volatility mainly through hedge accounting. We monitor any hedge accounting ineffectiveness that might lead to Income Statement volatility with a VaR measure and trigger, reported monthly. For our accounting policies for derivatives and hedge accounting, see Note 1 to the Consolidated Financial Statements.

We hedge our foreign currency funding positions back to sterling, so our foreign exchange positions tend to be residual exposures that remain after hedging. These exposures could be, for example, to 'spot' foreign exchange rates or to cross currency basis. We monitor foreign exchange risk against absolute net exposures and VaR-based limits and triggers.

For more on this, see 'Funding strategy' and 'Term issuance' in the 'Liquidity risk' section.

**Risk monitoring and reporting** (audited)

We monitor our non-traded market risks using sensitivities, VaR and stress tests. We report them against limits and triggers to senior management daily and to ALCO and ERCC each month. The VaR we report captures all key sources of volatility (including interest rate and spread risks) to fully reflect potential volatility.

NON-TRADED MARKET RISK REVIEW

**Interest rate risk**

**Yield curve risk**

The table below shows how our net interest income would be affected by a parallel shift (both up and down) applied instantaneously to the yield curve at 31 December 2022 and 31 December 2021 In 2022, we moved to focus on 100 basis points (bps) from previously disclosed sensitivities of 50bps and 25bps. The shift reflects a more realistic stress in the current rate environment. We have replaced the previously disclosed sensitivities of 50bps and 25bps for 2021 with 100 bps sensitivities for consistency with 2022.

2022 compared to 2021

We regularly review our risk models and metrics including underlying modelling assumptions to ensure they continue to reflect the risks inherent in the current rate environment and incorporate regulatory expectations.

NII Sensitivity to a -100bps stress reduced to £(197)m (2021: £(440)m) as the risk of margin compression as a result of customer deposit rates becoming floored reduced in the higher rate environment. The NII sensitivity to a +100bps parallel stress reduced to £241m (2021: £318m), as the mix of customer liabilities changed in the higher rate environment.

EVE Sensitivity to a +100bps stress increased to £(487)m (2021: £(431)m) in the higher rate environment. This was driven by changes in the mix of customer liabilities, offset by a reduction in the profile of the structural position and customer behaviour in response to higher rates.

TRADED MARKET RISK

We have no significant traded market risk exposure. Our only exposure to traded market risk comes from providing permitted financial services to permitted customers. Our exposures are affected by market movements in interest rates, credit spreads, and foreign exchange rates. Traded market risk can reduce our net income. We hedge risks from client trades, and our books are as close to back-to-back as possible, with market risk hedged with Banco Santander SA or CCPs. This is required by Banking Reform legislation. We have two trading desks. The Link Desk transacts derivatives with our corporate clients that are permitted under the ring-fencing regime. The Retail Structured Products desk (RSP) sells investments to retail investors, through our UK branches and other channels. We calculate market risk capital using standard rules.

The Internal VaR for exposure to traded market risk at 31 December 2022 was less than £1m (2021: less than £1m).

OUR KEY LIQUIDITY RISKS (audited)

Through our LRA framework, we manage our funding or structural contingent and market liquidity risks wherever they arise. This can be in retail and corporate deposit outflows, wholesale secured and unsecured liquidity outflows and off-balance sheet activities. Other risks our framework covers include funding concentrations, intra-day cash flows, intra-group commitments and support, franchise retention and cross currency risk.

**Our main sources of liquidity** 

Customer deposits finance most of our customer lending. Although these funds are mostly callable, in practice they give us a stable and predictable core of funding. This is due to the nature of retail accounts and the breadth of our retail customer relationships.

We have a strong wholesale funding investor base, diversified across product types and geographies. Through the wholesale markets, we have active relationships in many sectors including banks, other financial institutions, corporates and investment funds. We access the wholesale funding markets through the issuance of capital, senior unsecured debt, covered bonds, structured notes and short-term funding. We also access these markets through securitisations of certain assets of Santander UK plc and our operating subsidiaries. For more on our programmes, see Notes 14, 26 and 27 in the Consolidated Financial Statements.

We generate funding on the strength of our own balance sheet, our own profitability and our own network of investors. In addition, we have access to UK Government funding schemes. We comply with rules set by the PRA, other regulators, and Banco Santander standards. While we manage, consolidate and monitor liquidity risk centrally, we also manage and monitor it in the business area it comes from.

**Our main uses of liquidity** 

Our main uses of liquidity are to fund our lending in Retail Banking, Consumer Finance and Corporate & Commercial Banking, to pay interest and dividends, and to repay debt. Our ability to pay dividends depends on various factors. These include our regulatory capital needs, the level of our distributable reserves, and our financial performance. We also use liquidity to pay for business combinations.

LIQUIDITY RISK MANAGEMENT

**Introduction** 

We manage liquidity risk on a consolidated basis in our CFO division, which is our centralised function for managing funding, liquidity and capital. We created our governance, oversight and control frameworks, and our LRA, on the same consolidated basis.

Under the PRA's liquidity rules, Santander UK plc and its subsidiary Cater Allen Limited form the RFB Domestic Liquidity Sub-group (the RFB DoLSub), which allows them to collectively meet regulatory requirements to manage liquidity risk. Each member of the RFB DoLSub will support the other by transferring surplus liquidity in times of stress.

**Risk appetite**

Our LRA is based on the principles of liquidity management we use to manage our balance sheet. It also supports our need to meet or exceed regulatory rules. In line with our liquidity management principles, we avoid an over-reliance on funding from a single product, customer or counterparty. We also maintain enough unencumbered customer assets to support current and future funding and collateral requirements and maintain enough capacity to monetise liquid assets and other counterbalancing capacity on a timely basis.

Our LRA is proposed to the Risk division and the Board, which is then approved under advice from the Board Risk Committee. Our LRA, in the context of our overall Risk Appetite, is reviewed and approved by the Board each year, or more often if needed.

**Risk measurement** 

We use a number of metrics to manage liquidity risk. These include metrics that show the difference between cash and collateral inflows and outflows in different periods. They also include structural metrics, such as our level of encumbered assets.

**Ongoing business management**

Within our framework of prudent funding and liquidity management, we manage our activities to our liquidity risk appetite. We have clear responsibilities for short-term funding, medium-term funding, encumbrance, collateral and liquid asset management. This ensures we manage liquidity risks as part of our daily operations, strategy and planning.

Our liquidity management framework is split between short-term and strategic activities. Our short-term activities focus on intra-day collateral; management and maintaining liquid assets to cover unexpected demands on cash in a stress, such as large and unexpected deposit withdrawals by customers and loss of wholesale funding. Our strategic activities focus on ensuring we are not over reliant on any one source for funding and that we avoid excessive concentrations in the maturity of our funding.

We regularly test the liquidity of our eligible liquidity pool, in line with PRA and Basel rules. We do this by realising some of the assets by repurchase or outright sale to the market. We make sure that over any 12-month period we realise a significant part of our eligible liquidity pool. As well as our eligible liquidity pool, we always hold a portfolio of unencumbered liquid assets. Our LRA and PRA requirements determine the size and composition of this portfolio. These assets give us a source of contingent liquidity, as we can realise some of them in a stress to create liquidity by repurchase or outright sale to the market.

**Stress testing**

Our liquidity stress testing framework is central to our LRA measurement and monitoring. To fit with our risk appetite, the liquidity outflows that come from these stress tests must be fully covered with high-quality liquid assets, other liquid assets and appropriate management actions.

Our Risk division runs a range of stress tests. Our LRA stress test is a combination of three tests that cover idiosyncratic, market-wide and combined scenarios.

Our other tests consider scenarios such as a global economic slowdown that results in reduced confidence in banks, a slowdown in a major economy or a decline in access to liquidity. These are considered on both an acute and protracted basis. We also run severe combined stress tests which look at both a deep and prolonged UK recession that results in a reduction in wholesale funding availability and an idiosyncratic shock that would lead to retail and commercial outflows. We run a climate change stress, that assumes severe physical risks results in a reduction in retail deposits, increased use of corporate lending facilities and an increase in mortgage defaults.

We also conduct sensitivity analysis and reverse stress testing for instant liquidity shocks by each key liquidity risk. We do this to understand the impacts they would have on our LRA and our regulatory liquidity metrics.

We monitor our LCR to ensure we continue to meet the requirements. We also monitor the Net Stable Funding Ratio (NSFR), which was implemented on 1 January 2022.

**Risk mitigation** (audited)

The Board aims to make our balance sheet resilient at all times and for it to be perceived as such by stakeholders. This preserves our short and long-term viability. The Board recognises that as we are involved in maturity transformation, we cannot hold enough liquidity to cover all possible stress scenarios. The Board requires us to hold enough liquidity to make sure we will survive three plausible but severe stress scenarios (our LRA stress test, described above). We do this by maintaining a prudent balance sheet structure and approved liquid resources.

**Recovery and Resolution framework**

The CFO is the accountable SMF for recovery and resolution and the related work is managed by the CFO division. They are overseen by the Board Audit Committee and the Board.

We review and refresh our recovery plan each year. It sets out the risks, the indicators we use to monitor these risks, and the actions we can take to mitigate a capital, liquidity or combined stress event. We are confident that we have sufficient credible and executable options to respond to a wide variety of stresses, be they market-wide or idiosyncratic, in a timely and effective manner. Recovery indicators are both qualitative and quantitative and are embedded into risk frameworks. We monitor recovery capacity, headroom to recovery triggers and recovery indicators regularly. If necessary, we would invoke recovery early to mitigate the effects of a stress and restore our financial position and balance sheet strength.

We submitted our first self-assessment of our resolvability to the PRA in October 2021 and made targeted updates to it in February 2022. On 10 June 2022 we published our first resolvability public disclosure. This concludes that we have put in place capabilities that enable us to meet the Bank of England's resolution outcomes and that these are sufficiently flexible, so that they can be adapted to the specifics of failure as it unfolds, in order to credibly support the resolution in practice. Our capabilities are underpinned by comprehensive governance, testing and assurance arrangements, which seek to ensure that our resolution readiness is maintained and, where appropriate, enhanced on an ongoing basis. On the same day, the Bank of England published its own assessment of UK major banks' resolvability arrangements. The Santander UK specific section of the Bank of England's disclosure confirms that the Bank of England has not identified any material issues in relation to our approach to achieving the three resolution outcomes set out in the Resolvability Assessment Framework.

**Risk monitoring and reporting** (audited)

We monitor liquidity risk daily, weekly and monthly. We do this through different committees and levels of management, including ALCO and the BRC.

FUNDING RISK MANAGEMENT

**Funding strategy** 

Our funding strategy continues to be based on maintaining a conservatively structured balance sheet and diverse sources of funding to meet the needs of our business strategy and plans. The CFO Division maintains a funding plan that complies with the LRA and regulatory liquidity and capital requirements.

Most of our funding comes from customer deposits. We source the rest from a mix of secured and unsecured funding in the wholesale markets. Overall, this means that we do not rely too heavily on wholesale funds. We manage funding requirements by targeting a specific Liquidity Coverage Ratio, we ensure maturities are prefunded and capital/Minimum Requirements for Eligible Liabilities (MREl) requirements are prioritised. We also have checks and controls to limit our asset encumbrance from our secured funding operations.

As part of maintaining a diverse funding base, we raise funding in a number of currencies, including EUR and USD, and convert it into sterling through currency swaps to fund our commercial assets which are largely sterling denominated.

Our base of stable retail and corporate deposits is a key funding source for us. We leverage our large and diverse customer base to offer products that give us a long-term sustainable source of funding. We do this by focusing on building long-term relationships. Over 85% of our total core retail customer liabilities are covered by the Financial Services Compensation Scheme (the FSCS).

**Behavioural maturities**

The contractual maturity of our balance sheet assets and liabilities highlights the maturity transformation that underpins the role of banks to lend long term, but to fund themselves mainly with shorter-term liabilities, like customer deposits. We do this by diversifying our funding operations across a wide customer base, both in numbers and by type of depositor. In practice, the behavioural profiles of many liabilities show more stability and longer maturity than their contractual maturity. This is especially true of many retail and corporate deposits that, while they may be repayable on demand or at short notice, have shown good stability even in times of stress. We model behaviour profiles using our experience of customer behaviour. We use this data to determine the funds transfer pricing rates at which we reward and charge our business units for sources and uses of funds. We apply this rate until a customer changes to a different product or service offered by us or by one of our competitors.

We continue to maintain the quality of our retail, commercial and wholesale deposits. We aim to deepen our customer relationships across all customer segments. We do this to lengthen the contractual and behavioural profile of our liability base.

**Deposit funding** 

We mainly fund our Retail Banking, Consumer Finance and Corporate & Commercial Banking activities by customer deposits. We fund the rest through wholesale markets.

**Wholesale funding**

**Composition of wholesale funding** 

We are active in the wholesale markets and we have direct access to both money market and long-term investors through our funding programmes. This makes our wholesale funding well diversified by product, maturity, geography and currency. This includes currencies available across a range of channels from money markets, repo markets, senior unsecured, secured, medium-term and capital.

Santander UK plc is our main operating company issuer of senior unsecured debt, structured notes, short-term funding and covered bonds.

Our immediate parent Santander UK Group Holdings plc is the issuer of capital and MREL/Total Loss Absorbing Capacity (TLAC) eligible senior unsecured debt. Under CRR II, G-SIBs have been subject to the MREL standard. As part of this, UK resolution entities that are G-SIBs or are part of a G-SIB, including our immediate parent Santander UK Group Holdings plc, are required to meet the MREL minimum requirements, implemented through the Bank of England Statement of Policy on MREL in the UK. From 1 January 2020, the MREL requirement is the higher of (i) two times the Pillar 1 capital requirements and one times their Pillar 2A add-ons; (ii) 6% of CRR leverage exposures or (iii) two times the minimum leverage ratio requirement. The MREL requirements have been fully implemented from 1 January 2022.

The Company is subject to internal MREL as it meets the requirements of a material subsidiary of our ultimate parent Banco Santander SA.

We also access the wholesale markets through securitisations of certain assets of our operating subsidiaries. We also have access to UK Government funding schemes. Eligible collateral for these schemes includes all collateral that is eligible in the Bank of England's Discount Window Facility. We ensure that enough collateral is placed and available at the Discount Window.

**Issuance model and resolution** 

Banco Santander is a multiple point of entry resolution group. This means that should it fail, it would be split up into parts. Healthy parts might be sold or be kept as a residual group without their distressed sister companies. The resolution or recapitalisation of the distressed parts might be effected via 'bail in' of bonds that had been issued to the market by a regional intermediate holding company.

Santander UK is a single point of entry resolution group. This means that resolution would work downwards from the group's holding company i.e. Santander UK Group Holdings plc. Losses in subsidiaries would first be transferred up to Santander UK Group Holdings plc. If the holding company is bankrupt as a result, the group is deemed to be failing or likely to fail, it will be put into resolution. The 'bail in' tool is applied to the holding company, with the equity being written off and bonds written off or converted into equity as needed to recapitalise the group. Those bondholders would become the new owners, and the group would stay together.

Santander UK Group Holdings plc is the immediate holding company of Santander UK plc but does not guarantee its debts or other obligations. This structure is a Bank of England recommended configuration which aims to ensure the activities of the operating company are not disrupted as the Santander UK group goes through resolution, thereby maintaining continuity of services for customers.

(3)Includes funding from asset-backed securitisation vehicles where entities other than Santander UK plc are the asset originator.

2022 compared to 2021

–Together with our immediate parent, Santander UK Group Holdings plc, our overall funding strategy remains to develop and sustain a diversified funding base. We also need to fulfil regulatory requirements as well as support our credit ratings.

–Our funding costs improved with maturities refinanced at lower cost. Total wholesale funding decreased in 2022.

–We repaid £6.9bn of TFSME, with £25.0bn outstanding at year-end. In 2022, we utilised TFSME drawings to support mortgage lending in H122, but a successful retail funding campaign towards the end of the year and above-planned secured funding meant we were able to repay drawings. We expect similar annual repayments over the next 3 years.

–We issued a total of £8.6bn. Maturities in 2022 were £5.3bn.

–At 31 December 2022, 83% (2021:85%) of wholesale funding had a maturity of greater than one year, with an overall residual duration of 37 months (2021: 47 months).

–Our structural hedge position increased, with an average of £110bn over the last 12 months, and an average duration of c2.5 years.

–Our level of encumbrance from external and internal issuance of securitisations and covered bonds decreased again in 2022.

**Encumbrance** 

We encumber an asset if we pledge or transfer it as collateral against a liability. This means it is no longer available to secure funding, meet our collateral needs or be sold to reduce funding needs. Being able to pledge or transfer assets as collateral is a key part of a bank's operations. The main ways we encumber assets are that we: enter into securitisation, covered bonds, and repurchase agreements to access medium and long-term funding; enter into short-term funding transactions (including repurchase agreements and stock borrowing) as part of our liquidity management; pledge collateral as part of participating in payment and settlement systems; and post collateral as part of derivatives activity. We control levels of encumbrance by setting a minimum level of unencumbered assets after we factor in our funding plans, whether we can use our assets for our future collateral needs, the impact of a stress and our current encumbrance level.

Assets classified as readily available for encumbrance include cash and securities in our eligible liquidity pool. They also include other unencumbered assets that give us a source of contingent liquidity. We do not rely on these extra unencumbered assets in our LRA, but we might use them in a stress. We can create liquidity by using them as collateral for secured funding or through outright sale. This includes excess collateral already in a secured funding structure and collateral pre-positioned at central banks that is available for use in secured funding. All other loans and advances are classified as not readily available for encumbrance, however, they may still be suitable for use in secured funding structures.

**Encumbrance of customer loans and advances**

We have issued securitised products to a diverse investor base through our prime mortgage-backed and other asset-backed funding programmes. We have raised funding with mortgage-backed notes, both issued to third parties and retained – the latter being central bank eligible collateral for funding purposes in other Bank of England facilities. We also have a covered bond programme, under which we issue securities to investors secured by a pool of residential mortgages. For more on these programmes, see Notes 14 and 26 to the Consolidated Financial Statements.

THE SCOPE OF OUR CAPITAL ADEQUACY

**Regulatory supervision**

For capital purposes, we are subject to prudential supervision by the PRA, as a UK banking group, and by the European Central Bank (ECB) as part of the Banco Santander group. The ECB supervises Banco Santander as part of the Single Supervisory Mechanism (SSM). Although we are part of the Banco Santander group, we do not have a guarantee from Banco Santander SA and we operate as a standalone subsidiary. As we are part of the UK sub-group regulated by the PRA, we have to meet the PRA capital requirements on a standalone basis. We also have to show the PRA that we can withstand capital stress tests without the support of our parent. Reinforcing our corporate governance framework, the PRA exercises oversight through its rules and regulations on the Board and senior management appointments.

Santander UK Group Holdings plc is the holding company of Santander UK plc and is the head of the Santander UK group for regulatory capital and leverage purposes. Santander UK plc is the head of the ring-fenced bank sub-group and is subject to regulatory capital and leverage rules in relation to that sub-group. Our basis of consolidation for our capital disclosures is substantially the same as for our Consolidated Financial Statements.

CAPITAL RISK MANAGEMENT

The Board is responsible for capital management strategy and policy and ensuring that we monitor and control our capital within regulatory and internal limits. We manage our funding and maintain capital adequacy on a standalone basis. We operate within the capital risk framework and appetite approved by our Board. This reflects the environment we operate in, our strategy for each material risk and the potential impact of adverse scenarios or stresses on our capital.

**Management of capital requirements** (audited)

Our capital risk appetite aims to maintain capital levels appropriate to the level of stress applied, and the expected regulatory response. In:

–An adverse economic stress, which we expect once in 20 years, the firm should remain profitable and exceed all regulatory capital minimums at all times.

–A very severe economic stress, which we expect once in 100 years, and which has been designed to test any specific weaknesses of a firm's business model, the firm should meet all regulatory capital minimums at all times. This is subject to using regulatory buffers designed to absorb losses in such a stress.

**Management of capital resources** (audited)

We use a mix of regulatory and EC ratios and limits, internal buffers and restrictions to manage our capital resources. We also take account of the costs of differing capital instruments and capital management techniques. We also use these to shape the best structure for our capital needs. We decide how to allocate our capital resources as part of our strategic planning process. We base this in part on the relative returns on capital using both EC and regulatory capital measures. We plan for severe stresses and we set out what action we would take if an extremely severe stress threatened our viability and solvency. This could include not paying dividends, selling assets, reducing our business and issuing more capital.

**Risk measurement** 

We apply Banco Santander's approach to capital measurement and risk management for CRD IV. Santander UK plc is classified as a significant subsidiary of Banco Santander SA. For more on the CRD IV risk measurement of our exposures, see Banco Santander's Pillar 3 report.

**Key metrics** 

The main metrics we use to measure capital risk are CET1 capital ratio and total capital ratio. We continue to be in excess of overall capital requirements, minimum leverage requirements and minimum requirements for own funds and eligible liabilities (MREL).

**Stress testing** 

Each year we create a capital plan, as part of our ICAAP. We share our ICAAP with the PRA. The PRA then tells us how much capital (Pillar 2A), and of what quality, it thinks we should hold on top of our Pillar 1 requirements and buffer levels. We also develop a series of economic scenarios to stress test our capital needs and confirm that we have enough regulatory capital to meet our projected and stressed capital needs and to meet our obligations as they fall due.

In 2022, we developed a Climate Internal Scenario Analysis (CISA) to help understand better the potential impact of climate change on our business portfolios and balance sheet. The CISA outputs will form the basis of our 2022 ICAAP for climate risk by helping show if we need to hold more capital for climate risks and help us prioritise our actions for the next five years.

We augment our regulatory minimum capital with internal buffers. We hold buffers to ensure we have enough time to take action against unexpected changes.

**Risk mitigation** 

We designed our capital risk framework, policies and procedures to ensure that we operate within our Risk Appetite. We manage capital transferability between our subsidiaries in line with our business strategy, our risk and capital management policies, UK laws and regulations. There are no legal restrictions on us moving capital resources promptly, or repaying liabilities, between the Company and its subsidiaries except for distributions between Santander UK entities in the ring-fenced bank sub-group and Santander UK entities that are not members of the ring-fenced bank sub-group, where the PRA is required to assess the impact of proposed distribution prior to payment. For details on our Recovery framework in the event of a capital stress, see 'risk mitigation' in the 'Liquidity risk' section.

At 31 December 2022, Santander UK plc (RFB), Cater Allen Limited, Santander ISA Managers Limited and certain other non-regulated subsidiaries within the RFB were party to the RFB Sub-Group Capital Support Deed dated 17 December 2021. These parties were permitted by the PRA to form a core UK group, as defined in the PRA Rulebook, a permission which will expire on 31 December 2024. Exposures of each of the regulated entities to other members of the core UK group were exempt from large exposure limits that would otherwise apply. These intra-group exposures were risk-weighted at 0% and excluded from leverage exposure on a solo as well as consolidated basis. The purpose the Deed was to facilitate the prompt transfer of available capital resources from, or repayment of liabilities by, the non-regulated parties to any of the regulated parties in the RFB Sub-Group in the event that one of the regulated parties breached or was at risk of breaching its capital resources or risk concentrations requirements. For more details, see Note 31.

**Risk monitoring and reporting** 

We monitor and report regularly against our capital plan. We do this to identify any change in our business performance that might affect our capital. Each month, we also review the economic assumptions we use to create and stress test our capital plan. We do this to identify any potential reduction in our capital.

CAPITAL RISK REVIEW

**Meeting evolving capital requirements**

We target a CET1 management buffer of sufficient size to absorb volatility in CET1 deductions, capital supply and capital demand whilst remaining above the current and expected future regulatory CET1 requirement. Distribution restrictions would be expected to be applied if we were unable to meet both our minimum requirement, which consists of the Pillar 1 minimum plus Pillar 2A, the CRD IV buffers consisting of the Capital Conservation Buffer (CCB), the Countercyclical Capital Buffer (CCyB), and the Other Systemically Important Institutions Buffer (O-SII). Expected future regulatory CET1 requirements are impacted by the projected increase in the UK CCyB to 2% in July 2023.

**Impact of IFRS 9 on regulatory capital** 

Our ECL methodology takes account of forward-looking data and covers a range of possible economic outcomes, and so provision movements may result in increased pro-cyclicality of risk-based capital and leverage ratios. However, the impact is currently mitigated by our surplus of IRB model regulatory expected losses over provisions for exposures using the IRB approach. For such exposures (which include residential mortgages) the adverse impact on CET1 capital of provision increases from reserve movements is offset by the related reduction of the negative CET1 capital adjustment for regulatory expected loss amounts. Furthermore, the UK CRR transitional rules for the capital impact of IFRS 9 mean that adverse CET1 effects from increases in ECL-based provisions from the level of such provisions at 1 January 2018 are partly reduced until the end of 2024.

We reflect projections of ECL provisions in our capital position forecasting under base case and stress scenarios for ICAAP and capital management purposes. We also consider the dynamics of ECL in how we assess and manage capital risk. A period of economic instability, such as that seen in early 2020 due to the impacts of the Covid-19 pandemic, could significantly impact our results and our financial assets. It could also impact the amount of capital we have to hold. We take into account the volatility of ECL in our capital planning strategy.

The total subordination available to Santander UK plc senior unsecured bondholders was 20.4% (2021: 21.9%) of RWAs. Return on assets - profit after tax divided by average total assets was 0.49% (2021: 0.48%).

2022 compared to 2021

The CET1 capital ratio decreased 70bps to 15.4%. This was largely due to regulatory changes that took effect on 1 January 2022, and a special dividend paid in December 2022. The regulatory changes included the reintroduction of the full CET1 software asset deduction, and implementation of new definition of default regulatory guidance. The impact of increased RWAs £71.2bn (£68.1bn) and the special dividend were partially offset by post dividend retained earnings. We remain strongly capitalised with significant headroom to minimum requirements and MDA.

Total capital ratio decreased by 150bps to 20.4%, due to the lower CET1 capital ratio as outlined above and the reduction in AT1 and Tier 2 capital securities recognised following the end of the CRR Grandfathering period on 1 January 2022.

These are preference shares and innovative/hybrid Tier 1 securities. None of the instruments we issued before 1 January 2014 fully meet the CRD IV AT1 capital rules, which apply from that date. The instruments contribution to Tier 1 capital was phased out by CRD IV rules in 2021. The £750m Fixed Rate Reset Perpetual AT1 Capital Securities (net of issuance costs), the £800m Perpetual Capital Securities and the £500m Perpetual Capital Securities we issued since then fully meet the CRD IV AT1 capital rules.

**Tier 2 capital**

These are fully CRD IV eligible Tier 2 instruments and grandfathered Tier 2 instruments whose recognition as capital was phased out under CRD IV in 2021.

**MREL recapitalisation**

As at the end of 2022, we have down streamed £11.7bn of senior unsecured bonds from Santander UK Group Holdings plc as Internal MREL compliant, secondary non-preferential debt to Santander UK plc.

**Risk-weighted assets**

Total Risk-weighted assets at 31 December 2022 were £70.1bn (2021: £67.1bn), which are consistent with our regulatory filings.

OUR KEY PENSION RISKS

**Sources of risk**

Pension risk is one of our key financial risks. Santander UK plc is the sponsor of the Santander (UK) Group Pension Scheme (the Scheme), a defined benefit scheme. Our risk is that over the long-term the Scheme's assets are not enough to meet its liabilities as they fall due. If this happens, we could have to (or choose to) make extra contributions. We might also need to hold more capital to reflect this risk.

The Scheme, risk metrics and regulatory capital can be sensitive to changes in the assumptions of the key risk factors shown below.

---

| | |
|:---|:---|
| Key risks | Description |
| **Interest rate risk** | The risk that a decrease in (long-term) interest rates causes an increase in the value of the Scheme's liabilities that are not matched by an increase in the value of its assets. |
| **Inflation risk** | Annual pension increases are directly linked to RPI or CPI. The risk is that an increase in inflation causes an increase in the value of the Scheme's liabilities that are not matched by an increase in the value of its assets. |
| **Longevity risk** | The Scheme's liabilities are in respect of current and past employees and are expected to stretch beyond 2080 due to the long-term nature of the obligation. Therefore, the Scheme's liabilities are also impacted by changes to the life expectancy of Scheme members over time. |
| **Investment risk** | The risk that the return on the Scheme's assets is insufficient to meet the liabilities. |

---

For more on our defined benefit schemes, including sensitivity analysis of our key actuarial assumptions, see Note 30 to the Consolidated Financial Statements.

**Defined contribution schemes** 

We also have defined contribution schemes for some of our employees. These schemes carry far less market risk for us, although we are still exposed to operational and reputational risks. For more on our defined contribution schemes, see Note 30 to the Consolidated Financial Statements.

**The impact of our defined benefit schemes on capital** 

We take account of the impact of pension risk on our capital as part of our planning and stress testing process, considering measures such as the impact on CET1 and Pillar 2A, and also where relevant the impact on the related measures such as the leverage ratio.

Our defined benefit pension schemes affect capital in two ways:

–We treat an IAS 19 deficit as a liability on our balance sheet. We recognise deficit movements in Other Comprehensive Income, so this reduces shareholders' equity and CET1 capital. We treat an IAS 19 surplus as an asset. This increases shareholders' equity, but it is deducted in determining CET1 capital. An IAS 19 surplus/deficit is partially offset by a deferred tax liability/asset. These may be recognised for calculating CET1 capital depending on our overall tax position.

–The PRA takes pension risk into account in the Pillar 2A capital assessment in the annual ICAAP exercise. Pillar 2A is part of our overall regulatory requirement for CET1 capital, Tier 1 capital and total capital. For more on our regulatory requirements, see the 'Capital risk' section.

PENSION RISK MANAGEMENT

**Scheme governance**

For details of how the Scheme is governed and operates, see Note 30 to the Consolidated Financial Statements.

**Risk appetite**

Our risk appetite is a key consideration in all decisions and risk management activities related to the Scheme. Our pension risk appetite is reviewed by our Pensions Committee at least once a year. It is then sent to the Board for approval. We measure pension risk on both a technical provisions (funding) basis and an accounting (IAS 19) basis. We manage pension risk on both the accounting and the funding basis. Both bases are inputs into our capital calculations.

**Risk measurement**

Our key risk metrics include:

---

| | |
|:---|:---|
| Key risk metrics | Description |
| **Funding Deficit at Risk** | We use a VaR and a forward-looking stress testing framework to model the Scheme's assets and liabilities to show the potential deterioration in the funding position. |
| **Required Return** | This estimates the return required from the Scheme's assets each year to reach a pre-defined funding target by a fixed date in the future. |
| **Pensions Volatility** | We use a VaR and a forward-looking stress testing framework to model the volatility in the pension-related capital deduction. |

---

The Scheme invests in certain assets whose values are not based on market observable data, such as investments in private equity funds and property. See Note 30 to the Consolidated Financial Statements for more details. The risks of these assets are included in the metrics described above.

We perform stress tests for regulators, including for ICAAPs and PRA stress tests. For more on our stress testing, see the 'Risk governance' section.

Climate change scenario testing was developed in 2021 and refined in 2022 giving us the capacity to simulate risk exposures over an extended time horizon. The Trustee adopted a target of net zero by 2050. This target is now factored into Trustee decision making.

**Risk mitigation**

The key tools we use to maintain the above key risk metrics within appetite are:

---

| | |
|:---|:---|
| Key tools | Description |
| **Investment strategies** | The Trustee developed the following investment objectives to reflect their main duty to act in the best interests of Scheme beneficiaries:<br>–To maintain a diversified portfolio of assets of appropriate quality, security, liquidity and profitability to generate income and capital growth to meet, with new contributions from members and employers, the cost of current and future benefits that the Scheme provides<br>–To limit the risk that the assets fail to meet the liabilities<br>–To invest in a manner appropriate to the nature and duration of the expected future retirement benefit payments under the Scheme<br>–To minimise the Scheme's long-term costs by maximising asset returns net of fees and expenses whilst reflecting the objectives above.<br>The investment strategy is regularly reviewed, and its impact on Funding Deficit at Risk is considered.  |
| **Hedging strategies** | The Trustee employs asset-liability matching arrangements including the use of liability driven investment strategies, and has a hedging strategy to reduce key market risks, mainly interest rate and inflation risk, but also currency risk. We monitor available collateral and liquidity with the objective of ensuring we have sufficient collateral and/or liquidity available to meet any margin calls. |
| **Environmental, social and governance (ESG)** | The Trustee has established a Sustainability Committee which is responsible for overseeing the Scheme's policies, regulatory obligations and priorities in respect of climate change and wider ESG related matters. |

---

We look at the impact on our risk metrics when determining the appropriateness of the investment and hedging strategies.

**Risk monitoring and reporting**

We monitor pension risk each month and report on it at Pension Risk Forum, ERCC, Pensions Committee and, where thresholds are exceeded (or likely to be), to the Board Risk Committee and the Board in line with our pension risk appetite. We discuss any remedial action with the Trustee.

In addition, we monitor the performance of third parties who support the valuation of the Scheme's assets and liabilities.

PENSION RISK REVIEW

2022 compared to 2021

Asset de-risking continued in 2022 as part of the long-term goal to reduce the risk of the Scheme, in particular with listed equities being sold and investment grade corporate bonds being purchased. In 2022, the Scheme purchased a second annuity policy and entered into a second longevity swap. These covered most pensioners in the Scheme who retired since the first annuity purchase and longevity swap. There was also a significant focus on ensuring sufficient liquidity and collateral levels in the Scheme and securing a positive outcome for the 2022 triennial actuarial valuation with the Trustee.

Risk monitoring and measurement

Our main focus is to ensure the Scheme achieves the right balance between risk and reward whilst minimising the impact on our capital and financial position. At 31 December 2022, the Funding Deficit at Risk decreased to £860m (2021: £1,190m), mainly due to actions such as interest rate and inflation hedging, and the sale of growth assets, including listed equities, hedge funds and commercial property.

The impact from variations in the IAS 19 position on CET1 capital was not significant in 2022. For more on the impact of our defined benefit schemes on capital, see the 'Capital risk' section.

Accounting position

The accounting position deteriorated over 2022. The Scheme sections in surplus had an aggregate surplus of £1,050m at 31 December 2022 (2021: £1,572m) while there were no sections in deficit (2021: none). The overall funded position was a £1,050m surplus (2021: £1,572m surplus). There were also unfunded liabilities of £25mat 31 December 2022 (2021: £37m). The overall deterioration was mainly driven by negative asset returns over the period, partially offset by an increase in the discount rate due to rising gilt yields, and deficit contributions paid into the Scheme.

There remains considerable market uncertainty and while the actions above mitigate some of the impact of market movements on yields, our position could change materially over a short period.

For more on our pension schemes, including the asset allocation and our accounting assumptions, see Note 30 to the Consolidated Financial Statements.

Maturity profile of undiscounted benefit payments

The Scheme's obligation to make benefit payments extends over the long-term. This is expected to stretch beyond 2080. The graph below shows the maturity profile of the undiscounted benefit payments expected to be paid from the Scheme over its life at 31 December 2022:

Operational risk & resilience

---

| | |
|:---|:---|
| Overview<br>**Operational risk is the risk of loss or adverse impact due to inadequate or failed internal processes, people and systems, or external events. Operational resilience is the ability to prevent disruption occurring to the extent practicable; adapt systems and processes to continue to provide services and functions in the event of an incident; return to normal running promptly when a disruption is over; and learn and evolve from both incidents and near misses. The combined 'Operational Risk & Resilience Framework' reflects the importance of operational resilience and the intrinsically close links between the management of operational risk and the operational resilience of the organisation - Operational Resilience is the outcome of executing sound Operational Risk practices.** <br>**In this section, we explain how we manage operational risk, with a focus on our top operational risks. These top operational risks may change each year depending on the relative movement in importance among all operational risks. We also describe our operational risk event losses and developments in the year.**  | **Key metrics** <br>Operational risk losses (over £10,000, and excluding PPI) increased by 160% compared to 2021 |

---

OUR KEY OPERATIONAL RISKS

Operational risk is inherent in our business. As a result, we aim to manage it down to as low a level as possible, rather than eliminate it entirely. Operational risk events can have a financial impact and can also affect our business objectives, customer service and regulatory obligations. These events can include product mis-selling, fraud, process failures, system downtime and damage to assets or external events.

Our top operational risks are:

---

| | |
|:---|:---|
| Key risks | Description |
| **Cyber** | We rely extensively on the use of technology to support our customers and to run our business. While technology allows us to develop and improve the way we serve our customers, it is critically important that we protect our customers' data and provide them with a secure environment in which to deal with us. Failure to protect the data of Santander UK and its customers against theft, damage or destruction from cyber-attacks could cause operational disruption, unauthorised access, loss or misuse of data, breach of regulations, negative customer outcomes, financial loss or reputational damage. The value of the data itself, especially personal details of customers and employees is a focus of cyber criminals along with systems that enable cyber attacks to be monetised. It is therefore critical that we are resilient to cyber-attacks and can quickly recover from them. |
| **Data Management** | We use data in all of our services and products. Data Management risk is where this data does not support the business outcomes, either through incorrect decisions or offerings, due to issues with its data quality. Data quality issues may be caused by technology incidents or processing errors. |
| **Fraud** | Fraud can be committed by first parties (our customers), second parties (people known to our customers or us), third parties (people unknown to our customers or us), and internally by our staff. We are committed to protecting ourselves and our customers from fraud and to mitigating our fraud risk in an ever-evolving external fraud environment. |
| **IT** | As noted in Cyber, technology is vital to our processes and operations, and in providing service to our customers. IT risk arises from any event related to the use of technology supporting business processes, where the event may result in the unavailability or failure of systems or in processing errors that impact our customers or operations. This includes hardware or software failures, or issues caused by change. |
| **People** | People risks include all risks related to employees and third parties working for us, covering resource management, health, safety and wellbeing and employee relations. People risk is a transverse risk as resource capacity, capability, and engagement challenges impact all risk types. As we develop our working practices and adapt to changing circumstances, people impacts and risks continue to be key considerations. |
| **Third party** | We rely extensively on third parties, both within the Banco Santander group and outside of it, for a range of services and goods. These include outsourced services, such as IT infrastructure including increasing use of the Cloud, software development and banking operations. Regulations require us to classify other legal entities in the Banco Santander group as external suppliers, so we manage them as third parties. Many suppliers are also shared across the sector and this could increase risk due to complexity and capacity issues at the third parties. The failure of a supplier may cause operational disruption, breach of data security or regulations, negative customer impact, financial loss or reputational damage. |
| **Transformation and Change** | Change risk arises in any activity that transforms our business strategy, operating environment, or products and services we provide to our customers. Management of change risks is an integral part of our governance and our focus, given the potential for impacts across all areas of non-financial risk. Failure to ensure change is appropriately considered, funded, executed and managed could result in operational disruption, poor customer outcomes, financial loss, reputational damage and may impede our ability to meet regulatory requirements. |

---

We are also exposed to tax risk which, even though it is a lower risk for us, is still a high-profile risk and may include legacy items. We adopted the Code of Practice on Taxation for Banks in 2010.

OPERATIONAL RISK MANAGEMENT

**Risk appetite** 

We set our operational risk appetite at a Santander UK group level and we express it through measures approved by the Board. These include risk statements and metrics set against our main non-financial risk event types. We also set lower level triggers, qualitative parameters and quantitative thresholds across our business. We monitor our risk profile and performance against the risk appetite under several key risk areas, and we have processes to identify, assess, manage and report risks and events. We incorporate Banco Santander group principles and standards, regulatory requirements and best practice, where applicable. Coverage across the seven CRD IV loss event types is comprehensive and aligns to the key risk areas approved by ERCC.

**Risk measurement**

The key components of the operational risk toolset we use to measure and mitigate risk are:

---

| | |
|:---|:---|
| Operational risk toolset | Description |
| **Operational risk and control assessments** | Our business units identify and assess their operational risks to ensure they manage and control them within our operational risk appetite, and prioritise actions needed. Every area must identify and record their material risks, assess their controls for adequacy and then accept the risk or plan to address any deficiencies. We also use operational risk assessments and risk rating tools as key parts of change risk management. |
| **Risk scenario analysis** | We perform this across business units. It involves a top down assessment of our key operational risks. We update our scenarios each year. The analysis gives us insight into rare but high impact events and allows us to understand potential impacts and address issues. |
| **Key indicators** | Key indicators and their tolerance levels give us an objective view of risk exposure or the strength of a control at any point in time. They also show trends and give us early warning of potential increasing risk exposures. Of primary importance are our business-wide risk appetite indicators which show adherence to our risk appetite statements. |
| **Operational risk event and loss management** | Operational risk events occur when our controls do not operate as we planned and this leads to customer impact, financial loss, regulatory impacts and/or damage to our reputation. We use data from these processes to identify and correct any control weaknesses. We also use root cause analysis to identify emerging themes, to prevent or reduce the impacts of recurrence and to support risk and control assessments, scenario analysis and risk reporting. Our operational risk loss appetite sets the level of total operational risk loss (expected and unexpected) in any given year (on a 12-month rolling basis) that we consider to be acceptable. We track actual losses against our appetite, and we escalate as needed. |
| **Risk based insurance** | Where appropriate, we use insurance to complement other risk mitigation measures. |

---

**Risk mitigation**

We mitigate our key operational risks in the following ways:

---

| | |
|:---|:---|
| Key risks | Risk mitigation |
| **Cyber** | Protecting our customers, systems and data remains a top priority for us. We operate a layered defence approach which we regularly assess to ensure that it addresses the prevailing threats. We validate our controls using tests designed to replicate real-world cyber-attacks. Our cyber security experts assess our overall cyber security posture and report to management each month, and to ExCo, ERCC, BRC and Board at least twice a year. We assess cyber controls and risks each quarter using Banco Santander's Holistic Cyber Risk Framework. Keeping our systems secure is a bank-wide responsibility and we continue to enhance our staff training to support this. We also have targeted training for Board members, senior management and other employees. We continue to work with other banks through the Cyber Defence Alliance, where we share intelligence on cyber threats and effective strategies to counter them. We campaign to raise awareness and give customers the knowledge they need to avoid becoming victims of cyber attacks. As part of this, we run customer education campaigns, and we offer advice through our online security centre. We also have a cyber insurance policy to give us comprehensive cover to respond and recover losses and damages from security or system failures and any impact of a data breach. |
| **Data** | We continue to monitor and mitigate data risk through enhanced governance structures and processes supported by effective deployment of our risk and control library. We assess Data risk each year as part of the Risk and Control Self-Assessment (RCSA) process and update our risk profile as needed. Our data management programme is a key enabler to ensuring our data is fit for purpose and making improvements to our underlying processes and data governance. We are also embedding Data Marketplace as a holistic system for data management across the bank, ensuring a more robust and comprehensive approach for managing data. |
| **Fraud** | We operate layered security controls combining prevention and detection controls, to mitigate risks. The current fraud environment is incredibly challenging, and as such our current Fraud Transformation programme contains several projects that are designed to reduce the risks to us and our customers. We are committed to taking a more preventative approach to mitigate these risks. To help support customers, over the past five years we have created a series of fraud education and media campaigns, many of which focus on drawing public attention to common frauds, such as purchase scams, investment fraud, and money mules, and how to avoid them. |
| **IT** | We proactively monitor technology platforms and applications through automated alerts to detect events that may impact their performance or availability. We investigate material events to identify the root cause and remedial actions needed. We escalate these events as needed through the Santander Early Escalation Notification (SEEN) Process, and we review them each quarter to identify trends we need to remediate. We assess IT risk each year as part of the RCSA process and update our risk profile as needed. |
| **People** | We monitor people risks through the use of a broad range of operational risk indicators covering capacity, capability, engagement and diversity and inclusion. These are reviewed and refreshed annually to track and monitor all people related measures. We mitigate people risk through adopting various attraction and retention strategies throughout the employee lifecycle, and by delivering a competitive employee value proposition including hybrid working. All significant people-related change initiatives must have Operational Risk Assessments conducted. We also have processes to capture and assess people-related events. |
| **Third party** | We identify and assess the risk profile of each of our third party arrangements before onboarding and throughout the relationship. We also identify and measure key third party risks within our operational risk and control assessments. We capture and assess related events, and use operational risk indicators to measure the third party risk profile of the business. We aim to ensure that our suppliers meet our risk and control standards beginning with on-boarding, throughout our relationship with them, and during off-boarding. |
| **Transformation and change** | Risk management of Transformation and Change is integrated within our project governance framework, known as One Governance, which brings together project planning and prioritisation, cost discipline and risk management of all project portfolios under one unified system environment. Projects are initially subject to rigorous review to ensure that demand funded is prioritised based on what the bank should, needs and wants to do for the benefit of our customers clients, colleagues and franchise, a process which incorporates risk and regulatory considerations. At an individual initiative level, the key risk management requirements are supported by an initial Project Risk Rating (PRR) which considers the risk an initiative poses to us and allows application of risk-based governance. An Executive Risk Summary (ERS) and an Operational Risk Assessment (ORA) are completed for all but very low risk rated projects. Our Change Risk Oversight Group assesses and manages risks at portfolio level. We continue to take a measured approach to executing risk and delivering cost savings, with a focus on prioritisation and capacity management. |

---

**Risk monitoring and reporting**

Reporting is a key part of how we manage risk. We can identify exposures through our operational risk and control assessments, risk scenario analysis, key indicators, operational risk assessments and incidents and events. We report exposures for each business unit through regular risk and control forums. These include details of risk exposures and how we plan to mitigate them. We prioritise and highlight events that have a material impact on our customers, reputation or finance by reporting them to key executives and committees. We use The Standardised Approach (TSA) to calculate our Pillar 1 operational risk capital. We use an internal model aligned to the CRD IV advanced measurement approach to validate our Pillar 2 capital needs.

Our crisis management framework covers all levels of the business. It sets out possible triggers and how we will manage a crisis, and we test it at least annually. If an event occurs, our business continuity plans help us recover as quickly as possible and we undertake post incident reviews to identify learnings.

OPERATIONAL RISK REVIEW

**2022 compared to 2021** 

Operational risk event losses

The table below shows our operational losses in 2022 and 2021 for reportable events with an impact over £10,000, excluding conduct risk events (which we discuss separately in the 'Conduct and regulatory risk' section), by CRD IV loss event types.

(1) 2% volume in 2021 was previously categorised as Employment practices and workplace safety

The value of our operational risk losses (events over £10,000) increased by 160% in 2022 largely due to the AML penalty and the continued increase in Fraud losses. In line with general industry trends, the value and volumes of losses due to cases of External Fraud increased by 138% and 119% respectively. We continue to enhance our anti-fraud measures to help protect our customers. Additionally, we have observed a rise in the number of events and losses prompted by the increasing level of change, resulting from delivery of regulation, industry developments and the need to further digitalise the business.

Cyber risk

Information and cyber security remain a top risk and a priority. We experienced no notable data and cyber security incidents in 2022. We continue to see increasing ransomware attacks across all sectors driven by compromises in supply chain tools and we expect this trend to continue. We continue to invest in the right skills and resources to manage data and cyber risk. We also continue to monitor the cyber threat from the conflict in Ukraine.

Data risk

in 2022, we continued to monitor data management risk through the enhanced governance structures and processes put in place by our Chief Data Officer. Our Data Programme is progressing with clearly defined deliverables that will improve our ability to manage data and enhance our data management capabilities, in line with our approved Data Strategy.

Fraud risk

Fraud against our customers and the bank remains a top risk and a priority. Fraud levels across UK banks continued to rise in 2022. Social engineering techniques used by fraudsters are a significant threat to customers and outside of the bank's controls. As such, in line with peers, Authorised Push Payment (APP) fraud is our largest fraud type. We are focused on preventative measures and in response to increasing fraud attacks, we designed new fraud prevention tools to complement our existing prevention and detection systems and controls. We continue to deploy dynamic 'scam warnings' in our online banking payment process, enhancing fraud prevention controls for high-risk digital payments, presenting customers with tailored questions and warnings specific to their payment journey. We play an actively collaborate on fraud management with industry partners, through UK Finance and Stop Scams UK. In 2022, we continued our customer awareness campaigns on the most common frauds and scams.

IT risk

The importance of IT continued to be reiterated by some outages to customer services in 2022 and we continue progressing a wide programme to address the root causes and further reduce key risks within our IT estate. The programme is expected to deliver risk reduction over a three year horizon and progress is closely monitored though our risk governance.

People risk

This risk continues to be compounded by changes in operating models and the execution of our strategies. We continue to adapt and respond to these risks; in particular, the people risks associated with the phased relocation of our Head Office to Unity Place in Milton Keynes, which are under close monitoring and management. 2022 saw lower wellbeing-related absence but, in line with our peers, we continue to see raised attrition levels reflecting a more buoyant job market. Potential impacts on productivity are supported with our wellbeing and inclusion strategy, centred on helping colleagues through change. As appropriate, we advocate hybrid working to encourage colleagues to return to offices, and are providing support as external economic factors impact some colleagues.

Third party risk

We continue to rely extensively on third parties, both within the Banco Santander group and outside of it, for a range of goods and services. In 2022, we continued to evolve our processes. This included implementing a new Third Party Risk Management process and amending contracts with suppliers.

Transformation and change

The way in which we operate, the technology we rely on, and how we interact with our customers and stakeholders is constantly evolving, and consequently, our ability as an organization to meet this change is a key priority. In 2022, we continued our transformation to simplify the bank, digitise processes and customer journeys, reduce cost, extend internal capabilities and ensure a resilient operating model. This included reducing our property footprint and significant delivery against a diverse transformation agenda with specific focus on a migration to the cloud, further digitalisation and managing obsolescence. Ensuring change does not result in unacceptable impacts on our risk profile underpins our strategic decisions and is robustly managed.

Operational Resilience

We have committed that, by 2025, we will address the vulnerabilities identified in the first operational resilience self-assessment approved by the Board and submitted to our regulators in March 2022. Achieving this will enhance our resilience, i.e. the ability of Santander UK to recover its Important Business Services (IBS) within Impact Tolerance levels to avoid intolerable harm to customers, the firm, or the market, with focus on vulnerable customers. In 2022, we focused on enhancing and testing our firm-wide recovery strategies and readiness to respond to a range of potential external events. Our operational resilience programme was subject to independent external review in January 2022 and received a satisfactory rating from Internal Audit in July 2022. A programme is in progress to remediate identified asset vulnerabilities which could directly affect our ability to recover our IBS within Impact Tolerances in the event of an outage. We have introduced resilience assessments across technology, data, people, third parties, and premises, which enhance our ability to monitor, oversee and action issues. Input to these assessments include scenario test outputs, post incident reviews, metrics, RCSAs, and event data. The Board continues to be actively engaged in the operational resilience journey and in March 2023 are to approve our annual operational resilience self-assessment.

OUR KEY CONDUCT AND REGULATORY RISKS

Our purpose is to help customers and businesses prosper. To achieve this, we are committed to ensuring conduct strategy is embedded in our business, good outcomes for our customers is at the heart of what we do and that our proposition and initiative approval process, and systems, operation and controls are well designed and operating effectively. We see our key exposure to conduct and regulatory risk through the risk of errors in our product design, sales practices, post-sale servicing, operational processes, complaint handling, and the failure to supervise, monitor or control the activities of our employees. All of these may result in the risk that we do not meet our customers' needs, align to the expectations of our regulators, deliver the expected outcomes or observe required standards of market behaviour.

Our Conduct and Regulatory Framework is built on the following risks:

---

| | |
|:---|:---|
| Key risks | Description |
| **Regulatory** | The risk that we fail to adhere to laws, regulations and codes which could have serious financial, reputational and customer impacts, including the risk that we may be adversely impacted by changes and uncertainty around UK and international regulations. We categorise regulatory risk into financial and non-financial risk aligned to our main regulators - the PRA and FCA - and other UK regulators and authorities. As part of the Banco Santander group, we are also impacted indirectly through regulation by the Banco de España (the Bank of Spain) and by the ECB through the SSM. We also fall within the scope of US regulation. |
| **Product** | The risk that we offer products and services that do not result in good outcomes for our customers. |
| **Sales** | The risk that we sell products and services without giving customers enough information to make an informed decision, that we do not provide appropriate advice, or that we fail to take account of customer vulnerability. |
| **After-sale and servicing** | The risk that failures of our operations, processes, IT or controls result in poor customer outcomes. This includes the risks that we do not give appropriate after-sale communications to customers, make it difficult for customers to contact us, or that we fail to take account of customer vulnerability. It also includes the risk that our systems and controls do not prevent or detect fraud. |
| **Culture** | The risk that we do not maintain a culture that encourages appropriate behaviours and puts the customer at the heart of what we do. |
| **Competition** | The risk of financial harm, criminal liability, customer harm or reputational damage that we may incur because we fail to comply with relevant competition law or being involved in any competition law investigation or proceedings. |
| **Controls** | The risk that we do not supervise our employees effectively or that our systems and controls do not prevent or detect misconduct. |

---

CONDUCT AND REGULATORY RISK MANAGEMENT

**Risk appetite**

We aim to comply with all regulatory requirements, and we have no appetite to make decisions or operate in a way that leads to poor customer outcomes or which negatively impacts the market. Our Board approves our risk appetite each year, or more often if needed, and we cascade it to our business units through our risk framework and policies. We also agree lower level risk tolerance thresholds at least annually.

**Risk measurement**

Due to the links between our conduct, regulatory and operational risk frameworks, our tools to identify, assess, manage and report operational risks also apply where exposures have a conduct or regulatory risk impact.

We support our conduct and regulatory risk framework and policies with tools that aim to identify and assess new and emerging conduct risks. These include:

---

| | |
|:---|:---|
| Key tools | Description |
| **Strategy and business planning** | We align our overall corporate strategy, financial plans, risk appetite and operational capabilities through our annual process to set our strategy. We derive our business unit plans from our corporate strategy and they contain a view of conduct and regulatory risk. |
| **Quality assurance** | We subject sales and processes to internal quality assurance and, as needed, external monitoring. |
| **Operational risk and control assessments** | Our business and business support units assess our operational risks, systems and controls to give us a consolidated risk view across all our business areas. We complete the assessments through a central tool to evaluate and manage our residual risk exposures. |
| **Scenario testing and horizon scanning** | We consider conduct and regulatory risk in our scenario testing and review possible root causes and assumptions to determine the likelihood and impact, with actions to enhance our controls where required. |
| **Conduct risk reporting** | We use dashboards to give us a view of conduct risks across our business and manage conduct risk in line with our risk appetite. |
| **Compliance monitoring** | We carry out an annual conduct and regulatory risk assurance programme approved by the Board and tracked throughout the year. |

**Risk mitigation**

Our conduct and regulatory risk framework and policies set out the principles, standards, roles and responsibilities and governance for conduct and regulatory risk, such as:

---

| | |
|:---|:---|
| Policies | Description |
| **Product approval** | Our product approval process aims to minimise our conduct, regulatory or reputational risks in the design, marketing, sales and servicing of products and services. We assess our products and services within a formal framework to ensure they meet the needs and expectations of our customers, are within our risk appetite and agreed metrics, and to ensure processes and controls are in place. |
| **Suitable advice and information for customers** | We give guidance to advisers and staff on the key principles, requirements and ethical behaviours they must follow. This ensures our customers are sufficiently informed when they consider or make a buying decision. |
| **Training and competence** | We train our staff and require them to maintain a suitable level of competence to ensure customers can achieve appropriate outcomes. We invest in all our people to ensure that we achieve our mandatory risk objectives and that everyone acknowledges their personal responsibility to manage risk. We place focus on ensuring our colleagues are trained to recognise and support customers who may be vulnerable, or who may be experiencing financial stress, financial difficulty or financial abuse. We also have a dedicated Specialist Support Team that offers guidance to colleagues helping customers who may need more tailored solutions. |
| **Fair treatment of vulnerable customers** | Some customers may be impacted financially or personally as a result of their circumstances. Our Vulnerable Customer Policy gives business units a clear and consistent view of what vulnerability can mean and situations when customers may need more support. Our guidelines focus on identifying characteristics of vulnerability, understanding customer needs and the support and flexibility we can give to help. In addition to mandatory training, we train our customer-facing staff using real customer scenarios to enable our colleagues to deal with a wide range of sensitive issues. Our online Vulnerable Customer Support Tool gives our people more guidance and support, and our Specialist Support Team provides guidance for the most complex situations. We also consider vulnerability in every initiative, and adapt our technology to the needs of customers with vulnerability characteristics in our design and testing stages. We work with charities, authorities, trade associations and other specialists to develop our understanding of vulnerability. |

---

**Risk monitoring and reporting**

We consider conduct and regulatory risk in all our business decisions. Our material conduct and regulatory risk exposures are subject to, and reported against, our conduct and regulatory risk appetite statement, as well as lower level triggers and thresholds for action. We monitor the position to ensure we provide appropriate outcomes and meet regulatory expectations. We have specific fora and committees such as our Conduct and Compliance Forum, and business specific risk management fora to make decisions on conduct and regulatory risks and we report to the ERCC and BRBC. Our risk and control fora support management to control risks in their business units. Reporting includes conduct risk dashboards, with metrics across common areas. These include policy breaches logged, quality assurance and complaints, and commentary on trends and root causes to enable us to take effective action.

CONDUCT AND REGULATORY RISK REVIEW

2022 compared to 2021

To fully consider customer and conduct impacts across our business, we maintain a strong focus on robust oversight and control of the customer journey across all our products and services. In 2022, we continued to build on our progress and remain vigilant in taking a customer-focused approach in developing strategy, products, services and policies that support fair customer outcomes and market integrity, in particular in the context of regulator and government driven initiatives. As part of this, we:

–Assessed the views and new policy areas in the FCA's 2022/23 Business Plan. The key focus is on three main areas: reducing and preventing serious consumer harm; setting and testing higher standards; and promoting competition and positive change. We continue to consider and address these in our controls, product and service processes and frameworks, and we continue to adapt in line with the evolution of a digital economy.

–Delivered change to meet the evolving regulatory landscape, including changes brought about by the PSR: Confirmation of Payee Phase 2, Open Banking and PSD2, and the FCA consumer protection agenda.

–Following the implementation of the Contingent Reimbursement Model, a voluntary code to deal with authorised push payment (APP) fraud, we continue to engage with the industry and authorities, giving input and support to further develop the code's framework. We also considered the latest PSR proposals to give greater protection for consumers against APP scams.

–Further evolved our Financial Support team and SME support, with more investment in people and IT to ensure we continue to drive fair outcomes and can provide tailored support, whilst managing the anticipated increased inflow of customers affected by the rising cost of living. This included reviewing related FCA and LSB publications.

–Proactively contacted over 2 million customers who may be experiencing early signs of financial stress, to support them and try to help avoid longer term financial difficulty. We refer customers to internal and external sources of support and have ongoing customer engagement and support plans.

–Continued focus on financial support for our business customers as Pay As You Grow options have been exhausted for many BBLS customers and 3 year CBILS overdrafts are reaching maturity.

–Successfully transitioned to alternate reference rates for the vast majority of LIBOR agreements. Our focus remains on transitioning a small group of customers whose agreements still reference either synthetic Sterling LIBOR or USD LIBOR. We continue to contribute to FCA consultation papers on both.

–Continued to actively participate in schemes to ensure the long term future of access to cash, including supporting the set up of shared banking hubs and wider engagement with LINK and industry partners.

–Continued our Consumer Duty implementation programme remaining focused on ensuring that our product and services, communications, and control frameworks are enhanced to continue to support good customer outcomes.

Like all UK banks, we continue to see a demanding regulatory agenda focused on consumer outcomes and customer vulnerability, including Consumer Duty, and continue to evaluate the evolving regulatory environment, particularly in light of the FSM Bill, and the government's Edinburgh Reforms. Conduct risks will likely continue to rise in the near and medium-term, as banks deal with increasing numbers of personal and business borrowers who are impacted by the rising cost of living. When implementing change, we focus on ensuring that our strategy, leadership, governance arrangements, and approach to managing and rewarding staff does not lead to a detrimental impact on our customers, competition, or to market integrity. We also remain committed to protecting the personal data we collect and use, and respecting the data protection rights of our customers, our people and others associated with us.

For an update on key movements in our financial crime risk profile, see the 'Financial crime risk review' section.

Financial crime risk

Overview<br>Financial crime risk is the risk that we are used to further financial crime, including money laundering, sanctions evasion, terrorist financing, facilitation of tax evasion, bribery and corruption. <br>In this section, we describe our key financial crime risks and explain how we manage and mitigate financial crime risk. We also describe developments in the year.<br>

FINANCIAL CRIME RISK

OUR KEY FINANCIAL CRIME RISKS

We recognise that financial crime and associated illegal activity damages the customers and communities we serve. Criminals use the financial system to launder the profits of illegal activity such as human trafficking and to fund terrorism. Financial crime is therefore a high priority risk for us and we remain committed in our efforts to counter it by maintaining the highest ethical standards and conducting business in accordance with regulatory and legal requirements. We have adopted a bank wide anti-financial crime strategy (AFC) that sets out the principles of 'Deter, Detect and Disrupt' and invested in training our colleagues in how to identify and prevent financial crime.

We believe that having a comprehensive and effective financial crime risk management framework is a business imperative and a positive investment that protects us from legal, regulatory and reputational risks. This includes implementing policies, procedures, and maintaining effective systems and controls to prevent and detect financial crime. We may be adversely affected if we fail to effectively mitigate the risk that third parties or our employees facilitate, or that our products and services are used to facilitate financial crime. We adopt a risk-based approach in line with UK and international laws and standards, and we work with government, law enforcement and the private sector to help meet our commitments and to inform our AFC strategy.

Our key financial crime risks are:

---

| | |
|:---|:---|
| Key risks | Description |
| **Money laundering** | We are used by criminals to transform the proceeds of crime into seemingly legitimate money or other assets. |
| **Terrorist financing** | We are used by terrorists to deposit, distribute or collect funds that are used to fund their activity. |
| **Sanctions** | We do not identify payments, customers or entities that are subject to economic or financial sanctions. |
| **Bribery and corruption** | We fail to put in place effective controls to prevent or detect bribery and corruption. |
| **Facilitation of tax evasion** | We fail to put in place effective systems and controls to prevent the facilitation of tax evasion. |

---

FINANCIAL CRIME RISK MANAGEMENT

**Risk appetite**

Financial crime risk appetite is the level of financial crime risk we are prepared to accept in carrying out our activities. This is approved at Board level and shared across the business, with limits specified to control exposures and activities that have material risk implications for us and the communities we are part of. Our customers and shareholders will be impacted if we do not mitigate the risk that we are being used to facilitate financial crime. We seek to comply with applicable UK and international sanctions laws and other regulations and make sure our risk appetite adapts to external events. We have minimal tolerance for residual financial crime risk, bribery and corruption risk, facilitation of tax evasion risk and zero tolerance for non-compliance with sanctions laws and regulations. We require employees and third parties acting on our behalf to act with integrity, due diligence and care. We have no appetite for non-compliance with financial crime laws or regulations by employees or persons acting for or on our behalf.

**Risk measurement**

We measure our exposure to financial crime risk regularly. Our AFC strategy and frameworks set the strategic direction for risk management by defining standards, objectives and responsibilities for all areas of the business. It supports senior management in effective risk management and developing a strong risk culture. We screen and risk rate all our customers and monitor activity to identify potential suspicious behaviour. We complete ad-hoc reviews based on key trigger events. Our Financial Intelligence Unit assesses specific types of threat, drawing on data from law enforcement and public authorities.

**Risk mitigation**

We take a proactive approach to mitigating financial crime risk. Our financial crime risk frameworks are supported by policies and standards which explain the requirements for mitigating money laundering, terrorist financing, sanctions compliance risks, bribery and corruption, and facilitation of tax evasion risks. We update these regularly to ensure they reflect new requirements and industry best practice. We support our colleagues to make sure they can make the right decisions at the right time. We raise awareness and provide role-specific training to build knowledge of emerging risks.

Key elements of our financial crime risk mitigation approach are that we:

–Undertake customer due diligence measures for new and existing customers, which include understanding their activities and banking needs

–Conduct risk assessments of customers, products, businesses, sectors and geographic risks to tailor our mitigation efforts

–Ensure all our staff complete mandatory financial crime training and, where required, role-based specialist training

–Deploy new systems to better capture, analyse and act on data to mitigate financial crime risks

–Partner with public authorities, the Home Office and the wider financial services industry to pool expertise and data. We are also involved in partnerships such as the Joint Money Laundering Intelligence Taskforce (JMLIT) which supports public-private collaboration to tackle financial crime.

**Risk monitoring and reporting**

We use key risk indicators to monitor our exposure to financial crime risks, and we report all issues in a timely manner. We work closely with subject matter experts across the business on all risk management and monitoring activities alongside more effective communication of policy changes. Regulators around the world continue to emphasise the importance of effective risk culture, personal accountability and the adoption and enforcement of risk-based requirements and adequate internal reporting processes and procedures. We continue to develop and enhance our financial crime operating and governance model to ensure that our control environment evolves at pace, keeping up with new or amended laws, regulations or industry guidance.

We adhere to a strong governance and reporting schedule to our ERCC and Financial Crime Committee, including analysis of the risks on the horizon, key risk indicators and a directional indication of the risk profile. Throughout 2022, management continued to update the risk committees on management and mitigation of financial crime risks including our activities to understand and address emerging challenges. We enhanced our financial crime risk indicators for effective risk reporting to senior management. We also regularly report to the Board Risk Committee on financial crime risk, the impact on the business and the actions we are taking to mitigate the risk.

FINANCIAL CRIME RISK REVIEW

2022 compared to 2021

Protecting the communities we serve from the social and economic impacts of financial crime remains a top priority for Santander. The financial crime landscape continues to be complex, with evolving regulatory and legal requirements, geo-political factors and changing criminal methods influencing the risks we face.

Changes to UK and global sanctions regimes in 2022, most notably those arising from the global response to the conflict in Ukraine, added significant complexity and operational demand upon our financial crime controls in a compressed period. This complexity is anticipated to continue in 2023 and we continue to monitor external developments and respond to their impacts on our financial crime controls, and have increased our resources to do so.

**FCA settlement on historical Business Banking AML controls**

In December 2022, the FCA concluded an investigation in relation to anti-money laundering controls in our Business Banking division in the period 31 December 2012 to 18 October 2017 following the payment of a £108m financial penalty.

The FCA's investigation focused on the identification, assessment and management of higher risk customers in our Business Banking division, including Money Services Businesses. It has now concluded, and no further action is anticipated by the FCA or any other authority in respect of this matter.

Santander UK takes its responsibilities regarding financial crime extremely seriously. For more, see Note 31. The Banco Santander group, including Santander UK, is fully committed to the fight against financial crime and will continue to meet all applicable financial crime regulations and legislation internationally and ensure effectiveness in our control environment.

**Financial Crime Transformation Programme**

Senior management and the Board engagement in the management of financial crime risk remains high, proportionate with one of our top risks. We continue to enhance our financial crime risk management capabilities across data, systems and subject matter expertise through our multiyear financial crime transformation and remediation programme. Continued areas of focus during 2022 includes;

–Ongoing training of colleagues in identifying, assessing, managing and reporting financial crime. Uplifting specialist role competencies through our Economic Crime Academy (ECA), enhancing the skill sets, knowledge and qualifications of key staff.

–Remediated data gaps in our customer records through back door remediation o help us manage financial crime risks.

–Maturing our Financial Crime Centre of Excellence to increase integration of financial crime risk management operations across our organisation.

Other key risks

---

| | |
|:---|:---|
| Overview | |

---

MODEL RISK

Generally, we consider a model to be a repeatable method that relies on assumptions to produce estimates of uncertain outcomes. Our key model risks arise from weaknesses and limitations in our models, or the incorrect use of a model. They include risks stemming from model data, systems, development, performance and governance. The most material models we use help us calculate our regulatory capital and credit losses, and perform stress tests.

---

| | |
|:---|:---|
| Model risk management | Description |
| **Risk appetite** | We express our model risk appetite through risk assessments of our material models. The Board is asked to agree this at least annually. |
| **Risk measurement** | We consider the percentage of models that have been independently assessed and the outcome of those reviews in measuring model risk. All models have assumptions and in general the more limitations those assumptions have, the higher the uncertainty and model risk. |
| **Risk mitigation** | We mitigate model risk through controls over how we use models throughout their life. We maintain a central model inventory that includes data on owners, uses and model limitations. We assess how important each model is to our business, and we track and resolve actions from independent reviews. We also maintain a clear approval path for new models and changes to existing models. |
| **Risk monitoring and reporting** | We report model risks and issues using management and control forums. We escalate issues when needed, or if our risk appetite is breached or showing adverse trends that could lead to future issues. |

---

2022 compared to 2021

We maintain a risk-based approach to management and control, focusing on model monitoring and independent model reviews on our more material models, such as those for credit losses or those with specifically defined regulatory standards. We remain focused on all our models given the recent changes in economic factors, with a particular focus on inflation and Bank Rate.

In 2022, we significantly developed our regulatory models, focusing on capital adequacy, to comply with new regulatory technical standards for banks. We expect this trend to continue over the next two years in line with supervisory expectations. We also developed new models for ECL reporting, with a focus on residential mortgages and commercial lending. The new models are designed to improve the overall control environment and accuracy of our risk measurement. They will also enable us to eliminate some long-standing Judgemental Adjustments required due to limitations in prior models.

Changes to models due to the cessation of LIBOR were completed. All model updates were governed in line with the complexity of change and the materiality of underlying models. We also focused on the models we used to support the BoE climate change stress test. These were new types of models with much longer forecast horizons. We expect work to continue in this area in the coming years. We updated our toolsets to help manage and control model risk, implementing a tool that supports the end-to-end model risk lifecycle. The tool provides a register for all models and their uses, automated reporting and governance workflow. The tool also has full traceability.

LEGAL RISK

Legal risk includes the legal consequences of operational risk, such as breach of contract, and operational risk with legal origins, such as a legally defective contract. We manage legal risk as a standalone risk type to reflect the continued pace and breadth of regulatory change across financial services.

---

| | |
|:---|:---|
| Risk management | Description |
| **Risk appetite** | We aim to make decisions and operate in a way that does not lead to legal risk. We have a low tolerance for residual legal risk. |
| **Risk measurement** | Due to the close links between our legal and operational risk frameworks, our tools to identify, assess, manage and report operational risks also apply where such exposures have a legal risk impact. |
| **Risk mitigation** | The Legal teams provide specialist advice and support to all business units to ensure we effectively manage legal risk. They help to implement a strong legal risk culture and decide whether legal advice should be sourced internally or externally. |
| **Risk monitoring and reporting** | Our internal legal risk reporting framework gives visibility of the Santander UK-wide legal risk profile. We provide regular updates of our key legal risks, issues or breaches, to senior management and the Board through our Legal & Corporate Governance Division. |

---

2022 compared to 2021

Our legal risk profile remained heightened but broadly stable in 2022, reflecting the high number and value of legal risks that we continue to manage. We continued to evaluate the evolving legal and regulatory environment, particularly in light of the Financial Services and Markets Bill and other changes set out in the Government's Edinburgh Reforms and the implications of the FCA's new Consumer Duty. We continued to align our outsourcing and material contracts to ensure EBA Outsourcing compliance, PRA/FCA requirements on operational resiliency and continuity, and Schrems II. We focused on the mitigation of legal and reputational risk relating to the FCA enforcement investigation into historical anti-money laundering systems and controls in our Business Banking division which concluded in December 2022. While litigated PPI claim volumes stabilised, there remains on-going large scale complex PPI related litigation brought by AXA, and a German criminal and tax investigation relating to historical dividend tax arbitrage transactions. We continue to manage our legal risk in relation to thematic Court actions and FOS complaints related to fraud, mortgages and commissions. In January 2023, the Legal risk framework was retired following a structural change when the Legal function moved to the CFO Division, as described in 'How we define risk' in 'Risk Framework' in the 'Risk governance' section.

STRATEGIC AND BUSINESS RISK

Strategic and business risk could impact our long-term success if it caused our business model to become out of date, ineffective, or inconsistent with our goals. This could arise if we fail to identify threats arising from the economy, regulation, competitors and/or changes in technology and customer expectations. It could also arise if we misjudge our capabilities, or ability to implement our strategy, or pursue initiatives that do not fit with our business model or miss opportunities we could benefit from.

---

| | |
|:---|:---|
| Risk management | Description |
| **Risk appetite** | We have a low to moderate appetite for strategic and business risk. This limits the risks we are prepared to take to achieve our strategic objectives and is aligned to our balanced, customer-centric business model. |
| **Risk measurement** | Our Board and senior management regularly review potential risks in our operations and plans to ensure we stay within risk appetite. |
| **Risk mitigation** | We manage strategic and business risk by having a clear and consistent strategy that takes account of external factors and our own capabilities. We have an effective planning process which ensures we adapt our strategy to reflect changes in key risks and opportunities. |
| **Risk monitoring and reporting** | We closely track our business environment, including long-term trends that might affect us in the future. As part of this, we report a range of indicators. |

---

2022 compared to 2021

Our business environment is always changing, and this affects how we do business. The post Covid-19 economic recovery was unexpectedly halted by the conflict in Ukraine bringing in geo-political uncertainties and exacerbating the cost of living crisis. We prudently managed our balance sheet in an increasing interest rate environment and are simplifying our operating model to offset pressures of the deteriorating macro environment. Mortgage volumes dropped post mini-budget and mortgage prices increased given increasing interest rates. We proactively reached out to our mortgage customers and gave them financial support where needed. We helped our customers manage their finances in a rising inflation environment by providing them with budget planning and management tools, as well as tips to cut spending. We will continue to work with all our customers through these difficult times and provide them targeted and practical support that they need.

We continue to face a demanding regulatory agenda and in July 2022, the FCA published the new Consumer Duty rules, which we are on track to deliver.

Climate change is a key part of our business decisions. In 2022, we complied with all climate change related regulation including engaging in the BoE's CBES. As part of the Banco Santander group, we have also set ourselves Green Finance targets until 2025.

Competitive pressures continued in 2022, mainly from established players. We remained competitive by launching new products such as a market leading e-Saver account, fixed rate ISA products and the Edge current account for our retail customers, and helping our business customers grow through the Santander Navigator and SME Toolkit. We also improved our digital capabilities through enhanced mobile app features like My Money Manager and Santander Boosts. We will continue to invest in our technology to provide a high-quality customer experience.

Overall, we remain focused on supporting customer needs, improving efficiency, and building a responsible and sustainable business, while continuing to progress with our agenda to tackle climate change. This will enable us to meet the changing needs of our customers and deliver improved returns over the long-term.

REPUTATIONAL RISK

Reputational risks can arise from internal and external factors. We seek to manage our reputation proactively, underpinned by our aim to be a responsible bank, and through our reputational risk framework. Reputational risk is not static; today's decisions may be judged by different standards tomorrow. We build this into our risk culture, evaluation and sanction procedures.

---

| | |
|:---|:---|
| Risk management | Description |
| **Risk appetite** | We have a low appetite for reputational risk, which is agreed by the Board at least each year. |
| **Risk measurement** | We assess our exposure to reputational risk daily. We base this on expert judgement and analysis of social, print, and broadcast media, and the views of political and market commentators. We also commission independent third parties to analyse our activities and those of our UK peers to identify reputational events, a decline in our reputation, and sector or thematic issues that impact our business. We also measure the perception of Santander UK by key stakeholders through regular interactions and review staff sentiment each year. |
| **Risk mitigation** | Our business units consider reputational risk as part of their operational risk and control assessments. We also consider it as part of our new product reviews. Our Corporate Communications and Responsible Banking, Legal and Regulatory Affairs and Marketing team helps business units to mitigate the risk and agree action plans as needed, as part of their role to protect our brand and reputation. |
| **Risk monitoring and reporting** | We monitor and report reputational risks and issues on a timely basis. Our Reputational Risk Forum reviews and escalates key issues to ERCC, RBC and the Board. We also report regularly to ExCo on Sustainability and Responsible Banking, and Public Affairs policies. |

---

Our Reputational and ESCC risk policies define how we create long-term value while managing those risks. Our ESCC policy covers Oil & Gas, Power Generation & Transmission, Mining & Metals and Soft Commodities. For example, financing is prohibited for project-related financing for new CFPP projects worldwide and we will only work with new clients with CFPPs to provide specific financing for renewable energy projects.

2022 compared to 2021

In 2022, our key reputational risks arose from the economic slowdown and the cost of living crisis. To manage this, we regularly and proactively shared information with key external stakeholders on the actions we took to support customers, colleagues and communities. Particular areas of external focus included our support for customers facing financial difficulties and increasing mortgage payments.

We also worked to explain how our processes and controls have changed and improved since the period related to the FCA penalty for historical shortcomings in our AML controls, settled in December 2022.

**Report of Independent Registered Public Accounting Firm**

**To the Board of Directors and Shareholders of Santander UK plc**

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Santander UK plc and its subsidiaries (the "Company") as of December 31, 2022 and 2021, and the related consolidated income statement, consolidated statement of comprehensive income, consolidated cash flow statement and consolidated statement of changes in equity for each of the three years in the period ended December 31, 2022, including the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022 in accordance with i) International Financial Reporting Standards as issued by the International Accounting Standards Board, and ii) UK-adopted International Accounting Standards.

**Basis for Opinion**

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters**

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the Board Audit Committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgements. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

**Credit Impairment Loss Allowance on loans and advances to customers**

As described in Notes 1 and 13 to the consolidated financial statements, expected credit losses ("ECL") are recognised for financial assets measured at amortised cost. The measurement of ECL reflects: a probability weighted amount that is determined by evaluating a range of possible outcomes; the time value of money; and information about past events, current conditions and forecasts of future economic conditions. The application of the ECL impairment methodology for calculating credit impairment loss allowances is highly susceptible to change from period to period and requires management to make assumptions in determining the estimate. The key judgements made by management in applying the ECL impairment methodology are: (i) the forward looking multiple economic scenarios; (ii) the probability weights assigned to multiple economic scenarios; (iii) assessing individual corporate stage 3 exposures; and (iv) determining judgemental adjustments. The Company's ECL was £931 million as of December 31, 2022.

The principal considerations for our determination that performing procedures relating to the credit impairment loss allowance on loans and advances to customers is a critical audit matter are due to the significant judgements being applied by management in determining (i) the forward looking economic scenarios, (ii) the probability weights applied to those scenarios (iii) individual corporate stage 3 provisions and (iv) judgemental adjustments. This in turn led to a high degree of auditor judgement, subjectivity and effort in performing procedures and evaluating audit evidence related to the methodology and judgement in assumptions used to determine the allowance; and the audit effort involved the use of professionals with specialised skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the credit impairment loss allowance. These procedures also included, among others, testing management's process for estimating expected credit losses; evaluating the appropriateness of model methodologies; testing the underlying data used in the model and evaluating the reasonableness of management's assumptions related to (i) multiple forward looking economic scenarios and their relative probability weights; (ii) judgemental adjustments; and (iii) expected future cash flows and collateral valuations of individually assessed corporate stage 3 exposures. Professionals with specialised skill and knowledge were used to assist in evaluating the reasonableness of the forward looking economic scenarios, probability weight assumptions, the sufficiency and appropriateness of the judgemental adjustments, and corporate real estate collateral valuations.

**Valuation of defined benefit pension surplus**

As described in Notes 1 and 30 to the consolidated financial statements, the Company operates a number of defined benefit pension schemes. The main scheme is the Santander (UK) Group Pension Scheme (the scheme). The scheme is in a net surplus of £1,050 million as of December 31, 2022. Any surplus or deficit of scheme assets over liabilities is recognised in the balance sheet as an asset (surplus) or liability (deficit). Management estimates the present value of the defined benefit obligation by projecting forward the growth in current accrued pension benefits to reflect inflation and salary growth to the date of pension payment, then discounted to present value. In determining the value of scheme liabilities, demographic and financial assumptions are made by management about life expectancy, inflation and discount rates. The scheme invests in certain assets whose values are not based on market observable data which totalled £3,100 million as of December 31, 2022. These illiquid assets included investments in unquoted equities and unquoted corporate bonds, as well as investments in property, infrastructure and hedge funds. These illiquid assets are valued by reference to the latest manager statements provided by the managers, adjusted for any cash movements since the latest valuation, with the exception of directly held property where the underlying asset valuations are prepared by an independent expert, adjusted for any cash movements where necessary since the latest valuation.

The principal considerations for our determination that performing procedures relating to the valuation of the defined benefit pension surplus is a critical audit matter are due to the significant judgements made by management in determining: (i) the life expectancy, inflation and discount rate assumptions; and (ii) the fair value of the scheme's illiquid assets, including adjustments for any capital changes and potential fair value movements since the last valuation date. This, in turn, led to significant auditor judgement, subjectivity and effort in performing procedures and evaluating audit evidence. The audit effort involved the use of professionals with specialised skill or knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of the defined benefit pension obligation and the valuation of illiquid assets. These procedures also included, among others, evaluating the defined benefit pension obligation by 1) testing the completeness and accuracy of the underlying data, and 2) the involvement of professionals with specialised skill and knowledge to assist in a) developing an independent range of the inflation rate, the discount rate and life expectancy assumptions, b) comparing the independent range of assumptions to management's assumptions to evaluate the reasonableness of management's assumptions and c) assessing the appropriateness of the methodologies used by management to determine these assumptions. Procedures over directly held property included, among others: (i) the involvement of professionals with specialised skill and knowledge to assist in assessing the appropriateness of the methodology and reasonableness of the key assumptions used by management's third party valuer for property and reviewing the reasonableness of the valuation for a sample of properties, (ii) for the other illiquid assets, obtaining third-party confirmations of the valuation directly from investment managers and comparing these against management's reported value, recalculating management's valuations and comparing them to the third-party confirmations and, if applicable, testing material capital changes in the period between the valuation and the entity's balance sheet date where there was a time lag, (iii) assessing evidence regarding the valuations, such as agreeing NAV statements from investment managers to audited fund financial statements where they were available, performing back testing of fair values to any recent transactions and reviewing controls reports for the investment managers where available.

**Goodwill impairment assessment - personal financial services cash generating unit**

As described in Notes 1 and 20 to the consolidated financial statements, the carrying amount of goodwill relating to the personal financial services ('PFS') cash generating unit ("CGU") was £1.17 billion as of December 31, 2022. Management undertakes an annual assessment to evaluate whether the carrying value of goodwill is impaired, carrying out this assessment more frequently if reviews identify indicators of impairment or when events or changes in circumstances dictate. Impairment is required where the carrying value of goodwill exceeds its recoverable amount. The recoverable amount of the CGU was determined based on the value in use ("VIU") methodology at each testing date. The VIU is calculated by discounting the cash flow projections for the CGU. The carrying value of the goodwill is based on the application of judgement in determining the basis of goodwill impairment testing methodology, including the need for planning assumptions and internal capital allocations. Estimates include forecast cash flows for CGUs, including estimated allocations of regulatory capital, the growth rate for the period beyond the initial cash flow projections and discount rates which factor in risk-free rates and applicable risk premiums.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment - personal financial services cash generating unit is a critical audit matter are due to the significant judgements by management in determining (i) the amount of regulatory capital and carrying value of the PFS CGU, (ii) the forecast cash flows, (iii) the discount rate and (iv) the growth rate for the period beyond the initial cash flow projections assumptions. This, in turn, led to significant auditor judgement, subjectivity and effort in performing procedures and evaluating audit evidence related to management's judgements and assumptions. In addition, the audit effort involved the use of professionals with specialised skill or knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures also included, among others, (i) testing management's process for determining the carrying value of individual CGU including internal capital allocations, (ii) evaluating the appropriateness of the methodology used to estimate the VIU, (iii) testing the completeness and accuracy of underlying data used in the model (iv) comparing an independent range of assumptions for the discount rate and the growth rate beyond the initial cash flow projections to management's assumptions to evaluate the reasonableness of management's assumptions, and (v) evaluating the reasonableness of the forecasted cash flows including comparing performance in recent years to the budgets and 3 year plans for the equivalent periods to assess the accuracy of the budgeting and forecasting process and (vi) assessing the appropriateness of the related disclosures. Professionals with specialised skill and knowledge assisted in the evaluation of the reasonableness of the discount rate, the growth beyond the initial cash flow projections and assessing the determination of the carrying value of the PFS CGU.

**Litigation and other regulatory matters**

As described in Notes 1, 29 and 31 to the consolidated financial statements, as of December 31, 2022, the provision for litigation and other regulatory matters of £136 million includes, among other items, a provision relating to a legal dispute regarding allocation of responsibility for a specific Payment Protection Insurance ("PPI") portfolio of complaints. There is also an ongoing investigation in relation to the historical involvement of Santander UK plc, Santander Financial Services plc and Cater Allen International Limited in German dividend tax arbitrage transactions for which management has determined that there are uncertainties that mean it is not currently possible to make a reliable assessment of the size of any potential liability. Significant judgement may be required when accounting for provisions, including in determining whether a present obligation exists, in assessing the likely outcome of future legal decisions and in estimating the probability, timing, nature and amount of any outflows that may arise from past events. These judgements are based on the specific facts available and often require specialist professional advice. There can be a wide range of possible outcomes and uncertainties, particularly in relation to legal actions, and regulatory and consumer credit matters.

The principal considerations for our determination that performing procedures relating to litigation and other regulatory matters is a critical audit matter are due to the significant judgements made by management when estimating the probability, timing, nature and amount of any outflows for the legal dispute for a specific PPI portfolio of complaints, and the German dividend tax arbitrage investigation. This in turn led to a high degree of auditor judgement, subjectivity and effort in performing procedures and evaluating audit evidence obtained.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management's assessment of the cases against the requirements of IAS 37, Provisions, Contingent Liabilities and Contingent Assets. These procedures also included, among others, (i) inquiries of internal legal counsel on the developments in respect to the significant cases (ii) obtaining and evaluating letters of audit inquiry from external legal counsel, (iii) evaluating the reasonableness of management's assessment regarding the probability of an outflow and the estimated amount of the obligation, where a reliable estimate can be formed and (iv) evaluating the sufficiency of the group's disclosures made in relation to each of the matters.

1. ACCOUNTING POLICIES

These financial statements are prepared for Santander UK plc (the Company) and the Santander UK plc group (the Santander UK group) under the UK Companies Act 2006. The principal activity of the Santander UK group is the provision of a wide range of banking and financial services to personal, business and corporate customers. Santander UK plc is a public company, limited by shares and incorporated in England and Wales having a registered office at 2 Triton Square, Regent's Place, London, NW1 3AN. It is an operating company undertaking banking and financial services transactions.

**Basis of preparation**

These financial statements incorporate the financial statements of the Company and entities it controls (its subsidiaries) made up to 31 December each year. The consolidated financial statements have been prepared on the going concern basis using the historical cost convention, except for financial assets and liabilities that have been measured at fair value. An assessment of the appropriateness of the adoption of the going concern basis of accounting is disclosed in the statement of going concern in the Directors' report.

**Compliance with International Financial Reporting Standards (IFRS)**

The consolidated financial statements of the Santander UK group and the separate financial statements of the Company comply with UK-adopted International Accounting Standards (IAS). The financial statements are also prepared in accordance with IFRS as issued by the International Accounting Standards Board (IASB), including interpretations issued by the IFRS Interpretations Committee, as there are no applicable differences from IFRS as issued by the IASB for the periods presented.

Disclosures required by IFRS 7 'Financial Instruments: Disclosure' relating to the nature and extent of risks arising from financial instruments, and IAS 1 'Presentation of Financial Statements' relating to objectives, policies and processes for managing capital, have been included in the Risk review section of this Annual Report. This information forms an integral part of these financial statements by this cross reference, is marked as audited, and is covered by the Independent auditor's report.

**Climate change**

Santander UK continues to develop its assessment of the potential impacts that climate change and the transition to a low carbon economy may have on the assets and liabilities recognised and presented in its financial statements.

Santander UK is mindful of its responsibilities as a responsible lender and is focused on ways to meet the objectives of the Paris Agreement on climate change and to support the UK's transition to a climate-resilient, net zero economy.

Santander UK's current climate change strategy focuses on three main areas to achieve Banco Santander's ambition to reach net zero emissions by 2050:

1. Managing climate risks by integrating climate considerations into risk management frameworks, screening and stress testing our portfolio for climate related financial risks, and setting risk appetites to help steer our portfolio in line with the Paris Agreement,

2. Supporting our customers' transition by developing products and services that promote a reduction in CO2 emissions, and

3. Reducing emissions in our operations and supply chain by focusing on continuous improvement in our operations, and environmental and energy management systems in accordance with ISO14001 and 15001, promoting responsible procurement practices and employee engagement.

Santander UK's current climate change strategy and its view of the risks associated with climate change and the transition to a low carbon economy are reflected in its critical judgements and accounting estimates, although climate change risk did not have a significant impact at 31 December 2022 and 2021, consistent with management's assessment that climate change and the transition to a low carbon economy are not currently expected to have a meaningful impact on the viability of the Santander UK group in the medium term.

At 31 December 2022 and 2021, management specifically considered the potential impact of climate change and the transition to a low carbon economy on:

–Loans and advances to customers (see Note 13 and the credit risk section of the Risk review). Some climate change risks arise due to the requirements of IFRS 9 and others relate to specific portfolios and sectors: 5 years,For Mortgages in Retail Banking and Commercial Real Estate lending in Corporate & Commercial Banking, the value of property collateral might be affected by physical impacts related to the frequency and scale of extreme weather events, such as flood and subsidence risk, or changing environmental performance standards for property.

–For automotive loans in Consumer Finance, the residual value of automotive vehicles might be impacted by diesel obsolescence and the transition to electric vehicles.

–For corporate lending in Corporate & Commercial Banking, certain sectors give rise to fossil fuel exposures, such as Oil & Gas, Mining & Extraction and Power Generation.

–Goodwill impairment assessment (see Note 20). Estimates underpinning the determination of whether or not goodwill balances are impaired are partly based on forecast business performance beyond the time horizon for management's detailed plans.

Future changes to Santander UK's climate change strategy may impact Santander UK's critical judgements and accounting estimates and result in material changes to financial results and the carrying values of certain assets and liabilities in future reporting periods.

**Recent accounting developments**

**Disclosure of Accounting Policies – Amendments to IAS 1 and IFRS Practice Statement 2**

In February 2021, the IASB amended IAS 1 Presentation of Financial Statements to require entities to disclose their material rather than their significant accounting policies. To support this amendment, the IASB also amended IFRS Practice Statement 2 Making Materiality Judgements to provide guidance on how to apply the concept of materiality. The amendments are effective for annual periods beginning on or after 1 January 2023 with earlier application permitted. The amendments have been applied in preparing these financial statements and, consequently, only material accounting policy information is disclosed.

**Future accounting developments**

At 31 December 2022, for the Santander UK group, there were no other significant new or revised standards and interpretations, and amendments thereto, which have been issued but which are not yet effective, or which have otherwise not been early adopted where permitted.

**Comparative information**

As required by US public company reporting requirements, these financial statements include two years of comparative information for the consolidated income statement, consolidated statement of comprehensive income, consolidated statement of changes in equity, consolidated statement of cash flows and related notes.

**Material accounting policy information**

The following material accounting policies have been applied in preparing these financial statements. For material accounting policies which involve the application of judgements or accounting estimates that are determined to be critical to the preparation of these financial statements see 'Critical judgements and accounting estimates'.

**Consolidation**

The consolidated financial statements incorporate the financial statements of the Company and entities (including structured entities) controlled by it and its subsidiaries.

The acquisition method of accounting is used to account for the acquisition of subsidiaries which meet the definition of a business.

Business combinations between entities under common control (i.e. fellow subsidiaries of Banco Santander SA, the ultimate parent) are outside the scope of IFRS 3 – 'Business Combinations', and there is no other guidance for such transactions under IFRS. The Santander UK group elects to account for business combinations between entities under common control at their book values in the acquired entity by including the acquired entity's results from the date of the business combination and not restating comparatives. Reorganisations of entities within the Santander UK group are also accounted for at their book values.

Credit protection entities established as part of significant risk transfer (SRT) transactions are not consolidated by the Santander UK group in cases where third party investors have the exposure, or rights, to all of the variability of returns from the performance of the entities.

**Revenue recognition**

**a) Interest income and expense** 

Interest and similar income comprise interest income on financial assets measured at amortised cost, investments in debt instruments measured at FVOCI and interest income on hedging derivatives. Interest expense and similar charges comprises interest expense on financial liabilities measured at amortised cost, and interest expense on hedging derivatives. Interest income on financial assets measured at amortised cost, investments in debt instruments measured at FVOCI and interest expense on financial liabilities other than those at fair value through profit or loss (FVTPL) is determined using the effective interest rate method.

Interest income is calculated by applying the effective interest rate to the gross carrying amount of financial assets, except for financial assets that have subsequently become credit-impaired (i.e. Stage 3), for which interest revenue is calculated by applying the effective interest rate to their amortised cost (i.e. net of the ECL provision). For more information on stage allocations of credit risk exposures, see 'Significant increase in credit risk' in the 'Santander UK group level – credit risk management' section of the Risk review.

**b) Fee and commission income and expense**

Fees and commissions that are not an integral part of the effective interest rate are recognised when the service is performed. Most fee and commission income is recognised at a point in time. Certain commitment, upfront and management fees are recognised over time but are not material. For retail and corporate products, fee and commission income consists principally of collection services fees, commission on foreign currencies, commission and other fees received from retailers for processing credit card transactions, fees received from other credit card issuers for providing cash advances for their customers through the Santander UK group's branch and ATM networks, annual fees payable by credit card holders and fees for non-banking financial products.

For insurance products, fee and commission income consists principally of commissions and profit share arising from the sale of building and contents insurance and life protection insurance. Commissions arising from the sale of buildings and contents insurance are recognised over the period of insurance cover, adjusted to take account of cancelled policies. Profit share income from the sale of buildings and contents insurance which is not subject to any adjustment is recognised when the profit share income is earned. Commissions and profit share arising from the sale of life protection insurance is subject to adjustment for cancellations of policies within 3 years from inception.

Fee and commission income which forms an integral part of the effective interest rate of a financial instrument (for example certain loan commitment fees) is recognised as an adjustment to the effective interest rate and recorded in 'Interest income'.

**c) Other operating income**

Other operating income includes all gains and losses from changes in the fair value of financial assets and liabilities held at fair value through profit or loss (comprising financial assets and liabilities held for trading, trading derivatives and other financial assets and liabilities at fair value through profit or loss), together with related interest income, expense, dividends, and changes in fair value of any derivatives managed in conjunction with these assets and liabilities. Changes in fair value of derivatives in a fair value hedging relationship are also recognised in other operating income. Other operating income also includes income from operating lease assets, and profits and losses arising on the sales of property, plant and equipment and subsidiary undertakings.

**Defined benefit pension schemes (see 'Critical judgements and accounting estimates')**

A defined benefit scheme is a pension scheme that guarantees an amount of pension benefit to be provided, usually as a function of one or more factors such as age, years of service or compensation. Pension costs are charged to 'Administration expenses', within the line item 'Operating expenses before impairment losses, provisions and charges' with the net interest on the defined benefit asset or liability included within 'Net interest income' in the income statement. The asset or liability recognised in respect of defined benefit pension schemes is the present value of the defined benefit obligation at the balance sheet date, less the fair value of scheme assets. The defined benefit obligation is calculated annually by independent actuaries using the projected unit credit method. The assets of the schemes are measured at their fair values at the balance sheet date.

The present value of the defined benefit obligation is estimated by projecting forward the growth in current accrued pension benefits to reflect inflation and salary growth to the date of pension payment, then discounted to present value using the yield applicable to high-quality AA rated corporate bonds of the same currency and which have terms to maturity closest to the terms of the scheme liabilities, adjusted where necessary to match those terms. In determining the value of scheme liabilities, demographic and financial assumptions are made by management about life expectancy, inflation, discount rates, pension increases and earnings growth, based on past experience and future expectations. Financial assumptions are based on market conditions at the balance sheet date and can generally be derived objectively.

Demographic assumptions require a greater degree of estimation and judgement to be applied to externally derived data. Any surplus or deficit of scheme assets over liabilities is recognised in the balance sheet as an asset (surplus) or liability (deficit). An asset is only recognised to the extent that the surplus can be recovered through reduced contributions in the future or through refunds from the scheme.

**Share-based payments**

The Santander UK group engages in cash-settled and equity-settled share-based payment transactions in respect of services received from certain of its employees. Shares of the Santander UK group's parent, Banco Santander SA are purchased in the open market by the Santander UK group (for the Employee Sharesave scheme) or are purchased by Banco Santander SA or another Banco Santander subsidiary (including awards granted under the Long-Term Incentive Plan and the Deferred Shares Bonus Plan) to satisfy share options or awards as they vest.

Options granted under the Employee Sharesave scheme and awards granted under the Transformation Incentive Plan are accounted for as cash-settled share-based payment transactions. Awards granted under the Long-Term Incentive Plan and Deferred Shares Bonus Plan are accounted for as equity-settled share-based payment transactions.

The fair value of the options granted under the Employee Sharesave scheme is determined using an option pricing model, which takes into account the exercise price of the option, the current share price, the risk-free interest rate, the expected volatility of the Banco Santander SA share price over the life of the option and the dividend growth rate. The fair value of the awards granted for the Long-Term Incentive Plan was determined at the grant date using an option pricing model, which takes into account the share price at grant date, the risk-free interest rate, the expected volatility of the Banco Santander SA share price over the life of the award and the dividend growth rate.

**Goodwill and other intangible assets (for goodwill see 'Critical judgements and accounting estimates')**

Goodwill represents the excess of the cost of an acquisition, as well as the fair value of any interest previously held, over the fair value of the share of the identifiable net assets of the acquired subsidiary, or business at the date of acquisition. Goodwill on the acquisition of subsidiaries and businesses is included in intangible assets. Goodwill is tested for impairment annually, or more frequently when events or changes in circumstances dictate and carried at cost less accumulated impairment losses. Gains and losses on the disposal of an entity or business include the carrying amount of goodwill relating to the entity or business sold.

Other intangible assets are recognised if they arise from contractual or other legal rights or if they are capable of being separated or divided from Santander UK and sold, transferred, licensed, rented or exchanged. The value of such intangible assets, where they are available for use, is amortised on a straight-line basis over their useful economic life of three to seven years and the assets are reviewed annually for impairment indicators and tested for impairment where indicators are present. Other intangible assets that are not yet available for use are tested for impairment annually or more frequently when events or changes in circumstances dictate.

Software development costs are capitalised when they are direct costs associated with identifiable and unique software products that are expected to provide future economic benefits and the cost of those products can be measured reliably. These costs include payroll, materials, services and directly attributable overheads. Internally developed software meeting these criteria and externally purchased software are classified in intangible assets on the balance sheet and amortised on a straight-line basis over their useful life of three to seven years, unless the software is an integral part of the related computer hardware, in which case it is treated as property, plant and equipment as described below. Capitalisation of costs ceases when the software is capable of operating as intended. Costs of maintaining software are expensed as incurred.

**Property, plant and equipment**

Property, plant and equipment include owner-occupied properties (including leasehold properties), office fixtures and equipment and computer software. Property, plant and equipment also includes operating leases where the Santander UK group is the lessor and right-of-use assets where the Santander UK group is the lessee. Internally developed software meeting the criteria set out in 'Goodwill and other intangible assets' above and externally purchased software are classified in property, plant and equipment where the software is an integral part of the related computer hardware (for example operating system of a computer). Classes of property, plant and equipment are depreciated on a straight-line basis over their useful life, as follows:

---

| | |
|:---|:---|
| Owner-occupied properties | Not exceeding 50 years |
| Office fixtures and equipment | 3 to 15 years |
| Computer software | 3 to 7 years |
| Right-of-use assets | Shorter of the lease term or the useful life of the underlying asset |
| Operating lease assets - vehicles | 2 to 4 years |

---

Depreciation is not charged on freehold land and assets under construction. Depreciation of operating lease assets where the Santander UK group is the lessor is described in 'Leases' below.

**Financial instruments (for impairment of debt instrument financial assets see' Critical judgements and accounting estimates: Credit impairment losses')**

**a) Initial recognition and measurement**

Financial assets and liabilities are initially recognised when the Santander UK group becomes a party to the contractual terms of the instrument. The Santander UK group determines the classification of its financial assets and liabilities at initial recognition and measures a financial asset or financial liability at its fair value plus or minus, in the case of a financial asset or financial liability not at FVTPL, transaction costs that are incremental and directly attributable to the acquisition or issue of the financial asset or financial liability. Transaction costs of financial assets and financial liabilities carried at FVTPL are expensed in profit or loss. Immediately after initial recognition, an expected credit loss (ECL) allowance is recognised for financial assets measured at amortised cost and investments in debt instruments measured at FVOCI.

A regular way purchase is a purchase of a financial asset under a contract whose terms require delivery of the asset within the timeframe established generally by regulation or convention in the marketplace concerned. Regular way purchases of financial assets classified as loans and advances, and issues of equity or financial liabilities measured at amortised cost are recognised on settlement date, being the date when the Santander UK group becomes a party to the contractual terms of the instrument; all other regular way purchases and issues are recognised on trade date.

**b) Financial assets and liabilities**

i) Classification and subsequent measurement

The Santander UK group classifies its financial assets in the measurement categories of amortised cost, FVOCI and FVTPL.

Financial assets and financial liabilities are classified as FVTPL where there is a requirement to do so or where they are otherwise designated at FVTPL on initial recognition. Financial assets and financial liabilities which are required to be held at FVTPL include:

–Financial assets and financial liabilities held for trading.

–Debt instruments that do not have solely payments of principal and interest (SPPI) characteristics. Otherwise, such instruments are measured at amortised cost or FVOCI, and

–Equity instruments that have not been designated as held at FVOCI.

Financial assets and financial liabilities are classified as held for trading if they are derivatives or if they are acquired or incurred principally for the purpose of selling or repurchasing in the near-term, or form part of a portfolio of financial instruments that are managed together and for which there is evidence of short-term profit taking.

In certain circumstances, other financial assets and financial liabilities are designated at FVTPL where this results in more relevant information. This may arise because it significantly reduces a measurement inconsistency that would otherwise arise from measuring assets or liabilities or recognising the gains or losses on them on a different basis, where the assets and liabilities are managed and their performance evaluated on a fair value basis or, in the case of financial liabilities, where it contains one or more embedded derivatives which are not closely related to the host contract.

The classification and measurement requirements for financial asset debt and equity instruments and financial liabilities are set out below.

*Financial assets: debt instruments*

Debt instruments are those instruments that meet the definition of a financial liability from the issuer's perspective, such as loans and government and corporate bonds. Classification and subsequent measurement of debt instruments depend on the Santander UK group's business model for managing the asset, and the cash flow characteristics of the asset.

Business model

The business model reflects how the Santander UK group manages the assets in order to generate cash flows and, specifically, whether the Santander UK group's objective is solely to collect the contractual cash flows from the assets or is to collect both the contractual cash flows and cash flows arising from the sale of the assets. If neither of these is applicable, such as where the financial assets are held for trading purposes, then the financial assets are classified as part of an 'other' business model and measured at FVTPL. Factors considered in determining the business model for a group of assets include past experience on how the cash flows for these assets were collected, how the assets' performance is evaluated and reported to key management personnel, and how risks are assessed and managed.

SPPI

Where the business model is to hold assets to collect contractual cash flows or to collect contractual cash flows and sell, the Santander UK group assesses whether the assets' cash flows represent SPPI. In making this assessment, the Santander UK group considers whether the contractual cash flows are consistent with a basic lending arrangement (i.e. interest includes only consideration for the time value of money, credit risk, other basic lending risks and a profit margin that is consistent with a basic lending arrangement). Where the contractual terms introduce exposure to risk or volatility that is inconsistent with a basic lending arrangement, the related asset is classified and measured at FVTPL.

Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are SPPI.

Based on these factors, the Santander UK group classifies its debt instruments into one of the following measurement categories:

–Amortised cost – Financial assets that are held for collection of contractual cash flows where those cash flows represent SPPI, and that are not designated at FVTPL, are measured at amortised cost. The carrying amount of these assets is adjusted by any ECL recognised and measured as presented in Note 13. Interest income from these financial assets is included in 'Interest and similar income' using the effective interest rate method. When estimates of future cash flows are revised, the carrying amount of the respective financial assets or financial liabilities is adjusted to reflect the new estimate discounted using the original effective interest rate. Any changes are recognised in the income statement.

–FVOCI – Financial assets that are held for collection of contractual cash flows and for selling the assets, where the assets' cash flows represent SPPI, and that are not designated at FVTPL, are measured at FVOCI. Movements in the carrying amount are recognised in OCI, except for the recognition of impairment gains or losses, interest revenue and foreign exchange gains and losses on the instrument's amortised cost which are recognised in profit or loss. When the financial asset is derecognised, the cumulative gain or loss previously recognised in OCI is reclassified from equity to profit or loss and recognised in 'Other operating income'. Interest income from these financial assets is included in 'Interest and similar income' using the effective interest rate method.

–FVTPL – Financial assets that do not meet the criteria for amortised cost or FVOCI are measured at FVTPL. A gain or loss on a debt instrument that is subsequently measured at FVTPL, including any debt instruments designated at fair value, is recognised in profit or loss and presented in the income statement in 'Other operating income' in the period in which it arises.

The Santander UK group reclassifies financial assets when and only when its business model for managing those assets changes. The reclassification takes place from the start of the first reporting period following the change. Such changes are expected to be very infrequent.

*Financial assets: equity instruments*

Equity instruments are instruments that meet the definition of equity from the issuer's perspective, being instruments that do not contain a contractual obligation to pay cash and that evidence a residual interest in the issuer's net assets. All equity investments are subsequently measured at FVTPL, except where management has elected, at initial recognition, to irrevocably designate an equity investment at FVOCI. When this election is used, fair value gains and losses are recognised in OCI and are not subsequently reclassified to profit or loss, including on disposal. ECLs (and reversal of ECLs) are not reported separately from other changes in fair value. Dividends, when representing a return on such investments, continue to be recognised in profit or loss as other income when the right to receive payments is established. Gains and losses on equity investments at FVTPL are included in 'Other operating income' in the income statement.

*Financial liabilities*

Financial liabilities are classified as subsequently measured at amortised cost, except for:

–Financial liabilities at FVTPL: this classification is applied to derivatives and other financial liabilities designated as such at initial recognition. Gains or losses on financial liabilities designated at FVTPL are presented partially in other comprehensive income (the amount of change in the fair value of the financial liability that is attributable to changes in the credit risk of that liability) and partially in profit or loss (the remaining amount of change in the fair value of the liability)

–Financial liabilities arising from the transfer of financial assets which did not qualify for derecognition, whereby a financial liability is recognised for the consideration received for the transfer. In subsequent periods, the Santander UK group recognises any expense incurred on the financial liability, and

–Financial guarantee contracts and loan commitments.

Contracts involving the receipt of cash on which customers receive an index-linked return are accounted for as equity index-linked deposits. The principal products are Capital Guaranteed/Protected Products which give the customers a limited participation in the upside growth of an equity index. In the event the index falls in price, a cash principal element is guaranteed/protected. The equity index-linked deposits contain embedded derivatives. These embedded derivatives, in combination with the principal cash deposit element, are designed to replicate the investment performance profile tailored to the return agreed in the contracts with customers. The cash principal element is accounted for as deposits by customers at amortised cost. The embedded derivatives are separated from the host instrument and are separately accounted for as derivatives.

*Sale and repurchase agreements (including stock borrowing and lending)*

Securities sold subject to a commitment to repurchase them at a predetermined price (repos) under which substantially all the risks and rewards of ownership are retained by the Santander UK group remain on the balance sheet and a liability is recorded in respect of the consideration received. Securities purchased under commitments to resell (reverse repos) are not recognised on the balance sheet and the consideration paid is recorded as an asset. The difference between the sale and repurchase price is treated as trading income in the income statement, except where the repo is not treated as part of the trading book, in which case the difference is recorded in interest income or expense.

Securities lending and borrowing transactions are generally secured, with collateral in the form of securities or cash advanced or received. Securities lent or borrowed are not reflected on the balance sheet. Collateral in the form of cash received or advanced is recorded as a deposit or a loan. Collateral in the form of securities is not recognised.

*Day One profit adjustments*

The fair value of a financial instrument on initial recognition is generally its transaction price (that is, the fair value of the consideration given or received). However, sometimes the fair value will be based on other observable current market transactions in the same instrument, without modification or repackaging, or on a valuation technique whose variables include only data from observable markets, such as interest rate yield curves, option volatilities and currency rates. When such evidence exists, the Santander UK group recognises a trading gain or loss at inception (Day One gain or loss), being the difference between the transaction price and the fair value. When significant unobservable parameters are used, the entire Day One gain or loss is deferred and is recognised in the income statement over the life of the transaction until the transaction matures, is closed out, the valuation inputs become observable, or an offsetting transaction is entered into.

ii) Impairment of debt instrument financial assets

The Santander UK group assesses on a forward-looking basis the ECL associated with its debt instrument assets carried at amortised cost and FVOCI and with the exposure arising from financial guarantee contracts and loan commitments. The Santander UK group recognises a loss allowance for such losses at each reporting date. The measurement of ECL reflects:

–An unbiased and probability-weighted amount that is determined by evaluating a range of possible outcomes.

–The time value of money, and

–Reasonable and supportable information that is available without undue cost or effort at the reporting date about past events, current conditions and forecasts of future economic conditions.

*Grouping of instruments for losses measured on a collective basis* 

We typically group instruments and assess them for impairment collectively where they share risk characteristics (as described in the Credit risk section of the Risk review) using one or more statistical models. Where we have used internal capital or similar models as the basis for our ECL models, this typically results in a large number of relatively small homogenous groups which are determined by the permutations of the underlying characteristics in the statistical models. We calculate separate collective provisions for instruments in Stages 1, 2 and 3 where the instrument is not individually assessed, as described below.

*Individually assessed impairments (IAIs)*

We assess significant Stage 3 cases individually. We do this for Corporate & Commercial Banking cases, but not for Business Banking cases in Retail Banking which we assess collectively. To calculate the estimated loss, we estimate the future cash flows under several scenarios each of which uses case-specific factors and circumstances. We then probability-weight the net present value of the cash flows under each scenario to arrive at a weighted average provision requirement. We update our assessment process every quarter and more frequently if there are changes in circumstances that might affect the scenarios, cash flows or probabilities we apply.

For more on how ECL is calculated, see the Credit risk section of the Risk review.

**–Write-off** 

For secured loans, a write-off is only made when all collection procedures have been exhausted and the security has been sold and/or a claim made on any mortgage indemnity guarantee or other insurance. In the corporate loan portfolio, there may be occasions where a write-off occurs for other reasons, such as following a consensual restructure or refinancing of the debt or where the debt is sold for strategic reasons into the secondary market at a value lower than its face value.

There is no threshold based on past due status beyond which all secured loans are written off as there can be significant variations in the time needed to enforce possession and sale of the security, especially due to the different legal frameworks that apply in different regions of the UK. For unsecured loans, a write-off is only made when all internal avenues of collecting the debt have been exhausted. Where appropriate the debt is passed over to external collection agencies. A past due threshold is applied to unsecured debt where accounts that are 180 days past due are written off unless there is a dispute awaiting resolution. Contact is made with customers with the aim to achieve a realistic and sustainable repayment arrangement. Litigation and/or enforcement of security is usually carried out only when the steps described above have been undertaken without success.

All write-offs are assessed / made on a case-by-case basis, taking account of the exposure at the date of write-off, after accounting for the value from any collateral or insurance held against the loan. The exception to this is in cases where fraud has occurred, where the exposure is written off once investigations have been completed and the probability of recovery is minimal. The time span between discovery and write-off will be short and may not result in an impairment loss allowance being raised. The write-off policy is regularly reviewed. Write-offs are charged against previously established loss allowances.

**–Recoveries**

**Recoveries of credit impairment charges are not included in the impairment loss allowance but are taken to income and offset against credit impairment charges. Recoveries of credit impairment charges are classified in the income statement as 'Credit impairment charges'.**

iii) Modifications of financial assets

The treatment of a renegotiation or modification of the contractual cash flows of a financial asset normally depends upon whether the renegotiation or modification is due to financial difficulties of the borrower or for other commercial reasons.

**–***Contractual modifications due to financial difficulties of the borrower:* where the Santander UK group modifies the contractual conditions to enable the borrower to fulfil their payment obligations, the asset is not derecognised. The gross carrying amount of the financial asset is recalculated as the present value of the renegotiated/modified contractual cash flows that are discounted at the financial asset's original EIR and any gain or loss arising from the modification is recognised in the income statement.

**–***Contractual modifications for other commercial reasons:* an assessment is performed to determine whether the terms of the new agreement are substantially different from the terms of the existing agreement, after considering changes in the cash flows arising from the modified terms and the overall instrument risk profile. Where terms are substantially different, such modifications are treated as a new transaction resulting in derecognition of the original financial asset, and the recognition of a 'new' financial asset with any difference between the carrying amount of the derecognised asset and the fair value of the new asset is recognised in the income statement as a gain or loss on derecognition. Where terms are not substantially different, the carrying value of the financial asset is adjusted to reflect the present value of modified cash flows discounted at the original EIR with any gain or loss arising from modification recognised immediately in the income statement.

Any other contractual modifications, such as where a regulatory authority imposes a change in certain contractual terms or due to legal reasons, are assessed on a case-by-case basis to establish whether or not the financial asset should be derecognised. For IBOR reform see Note 41.

iv) Derecognition other than on a modification

Financial assets are derecognised when the rights to receive cash flows have expired or the Santander UK group has transferred its contractual right to receive the cash flows from the assets and either: (1) substantially all the risks and rewards of ownership have been transferred; or (2) the Santander UK group has neither retained nor transferred substantially all of the risks and rewards but has transferred control.

Financial liabilities are derecognised when extinguished, cancelled or expired.

**c) Financial guarantee contracts and loan commitments**

Financial guarantee contracts are contracts that require the issuer to make specified payments to reimburse the holder for a loss it incurs because a specified debtor fails to make payments when due, in accordance with the terms of a debt instrument. Such financial guarantees are given to banks, financial institutions and others on behalf of customers to secure loans, overdrafts and other banking facilities.

Financial guarantee contracts are initially measured at fair value and subsequently measured at the higher of the amount of the loss allowance, and the premium received on initial recognition less income recognised in accordance with the principles of IFRS 15. Loan commitments are measured as the amount of the loss allowance (determined in accordance with IFRS 9 as described in Credit risk section of the Risk review). The Santander UK group has not provided any commitment to provide loans at a below-market interest rate, or that can be settled net in cash or by delivering or issuing another financial instrument.

For financial guarantee contracts and loan commitments, the loss allowance is recognised as a provision and charged to credit impairment charges in the income statement. The loss allowance in respect of revolving facilities is classified in loans and advances to customers to the extent of any drawn balances. The loss allowance in respect of undrawn amounts is classified in provisions. When amounts are drawn, any related loss allowance is transferred from provisions to loans and advances to customers.

**Derivative financial instruments (derivatives)**

Derivatives are contracts or agreements whose value is derived from one or more underlying indices or asset values inherent in the contract or agreement, which require no or little initial net investment and are settled at a future date. Transactions are undertaken in interest rate, cross currency, equity, residential property and other index-related swaps, forwards, caps, floors, swaptions, as well as credit default and total return swaps, equity index contracts and exchange traded interest rate futures, and equity index options.

Derivatives are held for risk management purposes. Derivatives are classified as held for trading unless they are designated as being in a hedge accounting relationship. The Santander UK group chooses to designate certain derivatives as in a hedging relationship if they meet specific criteria, as further described in 'Hedge accounting' below.

Derivatives are recognised initially (on the date on which a derivative contract is entered into), and are subsequently remeasured, at their fair value. Fair values of exchange-traded derivatives are obtained from quoted market prices. Fair values of over-the-counter derivatives are estimated using valuation techniques, including discounted cash flow and option pricing models.

Certain derivatives may be embedded in hybrid contracts. If the hybrid contract contains a host that is a financial asset, then the Santander UK group assesses the entire contract as described in the financial asset section above for classification and measurement purposes. Otherwise, embedded derivatives are treated as separate derivatives when their economic characteristics and risks are not closely related to those of the host contract; the terms of the embedded derivative would meet the definition of a stand-alone derivative if they were contained in a separate contract; and the combined contract is not held for trading or designated at fair value. These embedded derivatives are measured at fair value with changes in fair value recognised in the income statement. Contracts containing embedded derivatives are not subsequently reassessed for separation unless either there has been a change in the terms of the contract which significantly modifies the cash flows (in which case the contract is reassessed at the time of modification) or the contract has been reclassified (in which case the contract is reassessed at the time of reclassification).

All derivatives are carried as assets when their fair value is positive and as liabilities when their fair value is negative, except where netting is permitted. The method of recognising fair value gains and losses depends on whether derivatives are held for trading or are designated as hedging instruments and, if the latter, the nature of the risks being hedged. Gains and losses from changes in the fair value of derivatives held for trading are recognised in the income statement and included in Other operating income.

**Offsetting financial assets and liabilities**

Financial assets and liabilities including derivatives are offset and the net amount reported in the balance sheet when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or realise the asset and settle the liability simultaneously. The Santander UK group is party to a number of arrangements, including master netting arrangements under industry standard agreements which facilitate netting of transactions in jurisdictions where netting agreements are recognised and have legal force. The netting arrangements do not generally result in an offset of balance sheet assets and liabilities for accounting purposes, as transactions are usually settled on a gross basis.

**Hedge accounting**

The Santander UK group applies hedge accounting to represent, to the maximum possible extent permitted under accounting standards, the economic effects of its risk management strategies. Derivatives are used to hedge exposures to interest rates and exchange rates.

At the time a financial instrument is designated as a hedge (i.e. at the inception of the hedge), the Santander UK group formally documents the relationship between the hedging instrument(s) and hedged item(s), its risk management objective and strategy for undertaking the hedge. The documentation includes the identification of each hedging instrument and respective hedged item, the nature of the risk being hedged (including the benchmark interest rate being hedged in a hedge of interest rate risk) and how the hedging instrument's effectiveness in offsetting the exposure to changes in the hedged item's fair value attributable to the hedged risk is to be assessed. Accordingly, the Santander UK group formally assesses, both at the inception of the hedge and on an ongoing basis, whether the hedging derivatives have been and will be highly effective in offsetting changes in the fair value attributable to the hedged risk during the period that the hedge is designated. A hedge is normally regarded as highly effective if, at inception and throughout its life, the Santander UK group can expect, and actual results indicate, that changes in the fair value or cash flow of the hedged items are effectively offset by changes in the fair value or cash flow of the hedging instrument. If at any point it is concluded that it is no longer highly effective in achieving its documented objective, hedge accounting is discontinued.

Where derivatives are held for risk management purposes, and when transactions meet the required criteria for documentation and hedge effectiveness, the derivatives may be designated as either: (i) hedges of the change in fair value of recognised assets or liabilities or firm commitments (fair value hedges); (ii) hedges of the variability in highly probable future cash flows attributable to a recognised asset or liability, or a forecast transaction (cash flow hedges); or (iii) a hedge of a net investment in a foreign operation (net investment hedges). The Santander UK group applies fair value and cash flow hedge accounting, but not hedging of a net investment in a foreign operation.

**a) Fair value hedge accounting**

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the income statement, together with the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. Where the hedged item is measured at amortised cost, the fair value changes due to the hedged risk adjust the carrying amount of the hedged asset or liability. Changes in the fair value of portfolio hedged items are presented separately in the consolidated balance sheet in macro hedge of interest rate risk and recognised in the income statement within other operating income. If the hedge no longer meets the criteria for hedge accounting, changes in the fair value of the hedged item attributable to the hedged risk are no longer recognised in the income statement. For fair value hedges of interest rate risk, the cumulative adjustment that has been made to the carrying amount of the hedged item is amortised to the income statement using the effective interest method over the period to maturity. For portfolio hedged items, the cumulative adjustment is amortised to the income statement using the straight-line method over the period to maturity.

**b) Cash flow hedge accounting**

The effective portion of changes in the fair value of qualifying cash flow hedges is recognised in other comprehensive income in the cash flow hedging reserve. The gain or loss relating to the ineffective portion is recognised immediately in the income statement. Amounts accumulated in equity are reclassified to the income statement in the periods in which the hedged item affects profit or loss. When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in equity at that time remains in equity and is recognised in the income statement when the forecast transaction is ultimately recognised in the income statement. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in equity is immediately transferred to the income statement. The Santander UK group is exposed to cash flow interest rate risk on its floating rate assets, foreign currency risk on its fixed rate debt issuances denominated in foreign currency and equity price risk arises from the Santander UK group operating the Employee Sharesave scheme. Cash flow hedging is used to hedge the variability in cash flows arising from these risks.

**Securitisation transactions**

The Santander UK group has entered into arrangements where undertakings have issued mortgage-backed and other asset-backed securities or have entered into funding arrangements with lenders in order to finance specific loans and advances to customers. The Santander UK group has also entered into synthetic securitisation arrangements, as part of significant risk transfer (SRT) transactions to reduce its risk-weighted assets, where undertakings have issued credit-linked notes and deposited the funds raised as collateral for credit protection in respect of specific loans and advances to customers. As the Santander UK group has retained substantially all the risks and rewards of the underlying assets, such financial instruments continue to be recognised on the balance sheet, and a liability recognised for the proceeds of the funding transaction, or in the case of SRT transactions, collateral deposited.

**Impairment of non-financial assets (for goodwill see 'Critical judgements and accounting estimates')**

At each balance sheet date, or more frequently when events or changes in circumstances dictate, property plant and equipment (including operating lease assets) and intangible assets (including goodwill) are assessed for indicators of impairment. If indications are present, these assets are subject to an impairment review. The impairment review comprises a comparison of the carrying value of the asset or cash generating unit with its recoverable amount: the higher of the asset's or cash-generating unit's fair value less costs to sell and its value in use. The cash-generating unit represents the lowest level at which non-financial assets, including goodwill, are monitored for internal management purposes and is not larger than an operating segment.

The fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Value in use is calculated by discounting management's expected future cash flows obtainable as a result of the asset's continued use (after making allowance for increases in regulatory capital requirements), including those resulting from its ultimate disposal, at a market-based discount rate on a pre-tax basis. The recoverable amounts of goodwill have been based on value in use calculations.

For conducting goodwill impairment reviews, cash generating units are the lowest level at which management monitors the return on investment on assets.

**Leases (as lessor)**

Operating lease assets are recorded at cost and the difference between cost and residual value (RV) is depreciated over the life of the asset. Operating lease rental income and depreciation is recognised on a straight-line basis over the life of the asset. After initial recognition, residual values are reviewed regularly, and any changes are recognised prospectively through remaining depreciation charges.

Amounts due from lessees under finance leases and hire purchase contracts are recorded as receivables at the amount of the Santander UK group's net investment in the leases. Finance lease income is allocated to accounting periods to reflect a constant periodic rate of return on the Santander UK group's net investment outstanding in respect of the leases and hire purchase contracts. A provision is recognised to reflect a reduction in any anticipated unguaranteed RV. A provision is also recognised for voluntary termination of the contract by the customer, where appropriate.

**Income taxes, including deferred taxes**

The tax expense represents the sum of the income tax currently payable and deferred income tax.

A current tax liability for the current or prior period is measured at the amount expected to be paid to the tax authorities. Where the amount of the final tax liability is uncertain or where a position is challenged by a taxation authority, the liability recognised is the most likely outcome. Where a most likely outcome cannot be determined, a weighted average basis is applied.

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled, or the asset is realised based on rates enacted or substantively enacted at the balance sheet date. Deferred tax is charged or credited in the income statement, except when it relates to items recognised in other comprehensive income or directly in equity, in which case the deferred tax is also recognised in other comprehensive income or directly in equity.

Deferred and current tax assets and liabilities are only offset when they arise in the same tax reporting group and where there is both the legal right and the intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

**Cash and cash equivalents**

Following a decision by the IFRS Interpretations Committee in April 2022, Santander UK updated its accounting policy to exclude from cash and cash equivalents Reserves Collateralisation Accounts (RCAs) balances held at the Bank of England relating to Santander UK's participation in certain payments schemes. Instead, RCAs balances are classified as restricted balances and included within 'change in operating assets' in the cash flow statement. Prior periods have been restated see Note34.

For the purposes of the cash flow statement, cash and cash equivalents comprise balances with less than three months maturity from the date of acquisition, including cash and non-restricted balances with central banks, treasury bills and other eligible bills, loans and advances to banks, reverse repurchase agreements and short-term investments in securities. Balances with central banks represent amounts held at the Bank of England as part of the Santander UK group's liquidity management activities. It includes certain minimum cash ratio deposits held for regulatory purposes and reserves collateralised accounts in respect of Santander UK's participation in certain payments schemes which are required to be maintained with the Bank of England and are restricted balances.

**Provisions and contingent liabilities (see 'Critical judgements and accounting estimates')**

Provisions are recognised for present obligations arising as consequences of past events where it is more likely than not that a transfer of economic benefits will be necessary to settle the obligation, and it can be reliably estimated.

Customer remediation provisions are made for the estimated cost of making redress payments with respect to the past sales of products, using conclusions such as the number of claims the number of those that will be upheld, the estimated average settlement per case and other related costs. Provision is made for the anticipated cost of restructuring, including redundancy costs, when an obligation exists. An obligation exists when the Santander UK group has a detailed formal plan for restructuring a business, has raised valid expectations in those affected by the restructuring, and has started to implement the plan or announce its main features.

When a leasehold property ceases to be used in the business, provision is made where the unavoidable costs of the future obligations relating to the lease are expected to exceed anticipated rental income. The net costs are discounted using market rates of interest to reflect the long-term nature of the cash flows.

Loan commitments are measured as the amount of the loss allowance, determined in line with IFRS 9 as set out in the Credit risk section of the Risk review.

Contingent liabilities are possible obligations whose existence will be confirmed only by certain future events or present obligations where the transfer of economic benefit is uncertain or cannot be reliably measured. Contingent liabilities are not recognised but are disclosed unless they are remote.

**Critical judgements and accounting estimates**

The preparation of Santander UK's consolidated financial statements in accordance with IFRS requires management to make judgements, estimates and assumptions in applying the accounting policies that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based on amounts which differ from those estimates. Estimates, judgements and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. There has been no change in the inherent sensitivity of the areas of judgement in the period. Management have considered the impact of developments in principal risks and uncertainties, as set out in the Risk review, on critical judgements and accounting estimates.

The significant judgements, apart from those involving estimation, made by management in applying Santander UK's accounting policies in these financial statements (key judgements) and the key sources of estimation uncertainty that may have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities within the next financial year (key estimates), which together are considered critical to Santander UK's results and financial position, are as follows:

**a) Credit impairment charges** 

The application of the ECL impairment methodology for calculating credit impairment allowances is highly susceptible to change from period to period. The methodology requires management to make judgmental assumptions in determining the estimates. Any significant difference between the estimated amounts and actual amounts could have a material impact on the future financial results and financial condition. The impact of the cost of living crisis has increased the uncertainty around ECL impairment calculations and has required management to make additional judgements and accounting estimates that affect the amount of assets and liabilities at the reporting date and the amount of income and expenses in the reporting period. The key additional judgements due to the impact of the cost of living crisis mainly reflect the increased uncertainty around forward-looking economic data and the need for additional judgemental adjustments.

Included in Litigation and other regulatory provisions in Note 29 are amounts in respect of management's best estimates of liability relating to a legal dispute regarding allocation of responsibility for a specific PPI portfolio of complaints, and Plevin related litigation. Note 31 provides disclosure relating to ongoing factual issues and reviews that could impact the timing and amount of any outflows.

Note 31 includes disclosure relating to an investigation in relation to the historical involvement of Santander UK plc, Santander Financial Services plc and Cater Allen International Limited (all subsidiaries of Santander UK Group Holdings plc) in German dividend tax arbitrage transactions.

These judgements are based on the specific facts available and often require specialist professional advice. There can be a wide range of possible outcomes and uncertainties, particularly in relation to legal actions, and regulatory and consumer credit matters. As a result, it is often not possible to make reliable estimates of the likelihood and amount of any potential outflows, or to calculate any resulting sensitivities. For more on these key judgements and estimates, see Notes 29 and 31.

**c) Defined benefit pension schemes** 

The Santander UK group operates a number of defined benefit pension schemes as described in Note 30 and estimates their position as described in the accounting policy 'Pensions and other post retirement benefits'.

For more on each of these key judgements and estimates, see Note 30.

Sensitivity of defined benefit pension scheme estimates

For detailed disclosures, see 'Actuarial assumption sensitivities' in Note 30. The Scheme is invested in certain assets whose values are not based on market observable data, such as investments in private equity funds and property. Due diligence has been conducted to ensure the values obtained in respect of these assets are appropriate and represent fair value. Given the nature of these investments, we are unable to prepare sensitivities on how their values could vary as market conditions or other variables change.

**d) Goodwill**

The carrying amount of goodwill is based on the application of judgements including the basis of goodwill impairment calculation assumptions. Santander UK undertakes an annual assessment to evaluate whether the carrying amount of goodwill is impaired, carrying out this assessment more frequently if reviews identify indicators of impairment or when events or changes in circumstances dictate.

2. SEGMENTS

Santander UK's principal activity is financial services, mainly in the UK. The business is managed and reported on the basis of four segments, which are strategic business units that offer different products and services, have different customers and require different technology and marketing strategies.

–**Retail Banking** consists of two business units, Homes and Everyday Banking. Homes provides prime UK mortgage lending to owner occupiers and buy-to-let landlords with small portfolios. Everyday Banking provides banking services and unsecured lending to individuals and small businesses as well alongside wealth management for high-net-worth clients.

**–Consumer Finance** provides prime auto consumer financing for individuals, businesses, and automotive distribution networks.

**–Corporate & Commercial Banking** provides banking products and services to SMEs, mid-sized and larger corporates, typically with annual turnovers of between £2m and £500m as well as to Local Authorities and Housing Associations.

**–Corporate Centre** provides treasury services for asset and liability management of our balance sheet, as well as management of non-core and legacy portfolios.

Retail Banking delivers products through our omni-channel presence comprising branches, ATMs, telephony, digital and intermediary channels. Consumer Finance business is primarily introduced by car dealerships acting as our intermediary along with a small amount of new business introduced via digital channels. Corporate and Commercial Banking expertise is provided by relationship managers, product specialists and through digital and telephony channels, and cover clients' needs both in the UK and overseas. In addition, Corporate and Investment Banking (CIB) provided services to corporate clients with an annual turnover of £500m and above. Santander UK transferred a significant part of the CIB business to the London branch of Banco Santander SA under a part VII banking business transfer scheme which completed on 11 October 2021. The residual parts of the business were wound down or transferred to other segments.

In December 2022, we transferred £1.5bn (2021: £2.3bn; 2020: £3.2bn) of social housing loans, and £0.4bn of non-core Liabilities (2021: £0.9bn; 2020: £nil) to our CCB segment from Corporate Centre to reflect the way these assets are managed, and restated comparatives accordingly. This resulted in an increase in profit before tax in CCB of £2.9m (2021: decrease of £2.7m; 2020: decrease of £6.3m) and an equal but opposite impact in Corporate Centre.

The segmental data is prepared on a statutory basis of accounting, in line with the accounting policies set out in Note 1. Transactions between segments are on normal commercial terms and conditions. Internal charges and internal UK transfer pricing adjustments are reflected in the results of each segment. Revenue sharing agreements are used to allocate external customer revenues to a segment on a reasonable basis. Funds are ordinarily reallocated between segments, resulting in funding cost transfers disclosed in operating income. Interest charged for these funds is based on Santander UK's cost of wholesale funding. Interest income and interest expense have not been reported separately. The majority of segment revenues are interest income in nature and net interest income is relied on primarily to assess segment performance and to make decisions on the allocation of segment resources.

Assets and liabilities held at FVTPL, including derivatives, are mainly used to provide customers with risk management solutions, and to manage and hedge the Santander UK group's own risks, and do not give rise to significant overall net gains/(losses) in the income statement.

'Net gains on financial instruments mandatorily at FVTPL' includes fair value gains of £14m (2021: losses of £15m, 2020: gains of £89m) on embedded derivatives bifurcated from certain equity index-linked deposits, as described in the derivatives accounting policy in Note 1. The embedded derivatives are economically hedged, the results of which are also included in this line item and amounted to losses of £14m (2021: gains of £15m, 2020: losses of £88m). As a result, the net fair value movements recognised on the equity index-linked deposits and the related economic hedges were net gains of £nil (2021: £nil, 2020: £1m).

Exchange rate differences recognised in the Consolidated Income Statement on items not at FVTPL were £2,163m expense (2021: £242m income, 2020: £751m expense) and are presented in the line 'Other'. These are principally offset by related releases from the cash flow hedge reserve of £2,129m income (2021: £358m expense, 2020: £809m income) as set out in the Consolidated Statement of Comprehensive Income, which are also presented in 'Other'. Exchange rate differences on items measured at FVTPL are included in the line items relating to changes in fair value.

In 2022, the Santander UK group repurchased certain debt securities and subordinated liabilities as part of ongoing liability management exercises, resulting in a loss of £5m (2021 loss of £1m, 2020: loss of £24m).

The standard rate of UK corporation tax was 27% for banking entities and 19% for non-banking entities (2021: 27% for banking entities and 19% for non-banking entities; 2020: 27% for banking entities and 19% for non-banking entities). Tax for other jurisdictions is calculated at the rates prevailing in those jurisdictions.

The Santander UK group's effective tax rate for 2022 was 25.6% (2021: 26.7%, 2020: 21.6%). The tax on profit from continuing operations before tax differs from the theoretical amount that would arise using the basic corporation tax rate as follows:

The UK government announced in its budget on 3 March 2021 that it would increase the main rate of corporation tax by 6% to 25% with effect from 1 April 2023. This change was substantively enacted on 24 May 2021 and, as a result, the effect has been reflected in the closing deferred tax position included in these financial statements. The comparative 2020 results reflected an increase in tax rates by 2% following an announcement in the 2020 budget to reverse a previously planned rate reduction from April 2020.

A reduction in the Bank Surcharge rate from 8% to 3% was announced in October 2021 to be effective from 1 April 2023. This change in rate was substantively enacted on 2 February 2022 and as a result, the effects of this change have been reflected in the closing balance sheet position for deferred tax.

**Current tax assets and liabilities**

Movements in current tax assets and liabilities during the year were as follows:

---

| | | |
|:---|:---|:---|
| | | Group |
| | **2022** | 2021 |
| | **£m** | £m |
| Assets | **347** | 264 |
| Liabilities | **—** |  |
| **At 1 January** | **347** | 264 |

|  | **478** | 347 |
| Assets | **478** | 347 |
| Liabilities | **—** |  |
| **At 31 December** | **478** | 347 |

---

The amount of corporation income tax paid differs from the tax charge for the period as a result of the timing of payments due to the tax authorities, the effects of movements in deferred tax, adjustments to prior period current tax provisions and current tax recognised directly in other comprehensive income.

Santander UK proactively engages with HM Revenue & Customs to resolve tax matters relating to prior years. The accounting policy for recognising provisions for such matters are described in Note 1. It is not expected that there will be any material movement in such provisions within the next 12 months.

**Deferred tax**

The table below shows the deferred tax assets and liabilities including the movement in the deferred tax account during the year. Deferred tax balances are presented in the balance sheet after offsetting assets and liabilities where the Santander UK group has the legal right to offset and intends to settle on a net basis.

The deferred tax assets and liabilities above have been recognised in the Santander UK group on the basis that sufficient future taxable profits are forecast within the foreseeable future, in excess of the profits arising from the reversal of existing taxable temporary differences, to allow for the utilisation of the assets as they reverse. Based on the conditions at the balance sheet date, management determined that a reasonably possible change in any of the key assumptions underlying the estimated future taxable profits in the Santander UK group's three-year plan (described in Note 20) would not cause a reduction in the deferred tax assets recognised. At 31 December 2022, the Santander UK group had a recognised deferred tax asset in respect of UK capital losses carried forward of £nil (2021: £5m) included within tax losses carried forward. There are £nil unrecognised deferred tax assets on capital losses carried forward (2021: £nil).

10. DIVIDENDS ON ORDINARY SHARES

---

In 2022 an interim dividend of £1,014m (2021: £1,358m, 2020: £129m) was paid on the Company's ordinary shares in issue, £300m of which was a special dividend. These were paid following review and approval by the Board in line with our dividend policy.

11. DERIVATIVE FINANCIAL INSTRUMENTS

**a) Use of derivatives**

Santander UK undertakes derivative activities primarily to provide customers with risk management solutions and to manage and hedge its own risks. These derivative activities do not give rise to significant open positions in portfolios of derivatives. Any residual position is managed to ensure that it remains within acceptable risk levels, with matching transactions used to achieve this where necessary. When entering into derivatives, Santander UK employs the same credit risk management procedures to assess and approve potential credit exposures that are used for traditional lending.

For information on how Santander UK is managing the transition to alternative benchmark interest rates, see Note 41.

**b) Analysis of derivatives**

The table below includes the notional amounts of transactions outstanding at the balance sheet date; they do not represent actual exposures.

**c) Analysis of derivatives designated as hedges**

Santander UK applies hedge accounting on both a fair value and cash flow basis depending on the nature of the underlying exposure. We establish the hedge ratio by matching the notional of the derivative with the underlying position being hedged. Only the designated risk is hedged and therefore other risks, such as credit risk are managed but not hedged. For interest rate hedges, the designated hedged risk is determined with reference to the underlying benchmark rate.

**Fair value hedges**

Portfolio hedges of interest rate risk

Santander UK holds portfolios of fixed rate assets and liabilities which expose it to changes in fair value due to movements in market interest rates. We manage these exposures by entering into interest rate swaps. Each portfolio contains assets or liabilities that are similar in nature and share the risk exposure that is designated as being hedged.

The interest rate risk component is the change in fair value of fixed rate instruments for changes in the designated benchmark rate. Such changes are usually the largest component of the overall change in fair value. Separate hedges are maintained for each underlying currency. Effectiveness is assessed by comparing changes in fair value of the hedged item attributable to changes in the designated benchmark interest rate, with changes in the fair value of the interest rate swaps.

Micro hedges of interest rate risk and foreign currency risk

Santander UK accesses international markets to obtain funding, issuing fixed rate debt in its functional currency and other currencies. We are therefore exposed to changes in fair value due to changes in market interest rates and/or foreign exchange rates, principally in USD and EUR, which we mitigate through the use of receive fixed/pay floating rate interest rate swaps and/or receive fixed/pay floating rate cross currency swaps.

The interest rate risk component is the change in fair value of the fixed rate debt due to changes in the benchmark rate. The foreign exchange component is the change in the fair value of the fixed rate debt issuance due to changes in foreign exchange rates prevailing from the time of execution. Effectiveness is assessed by using linear regression techniques to compare changes in the fair value of the debt caused by changes in the benchmark interest rate and foreign exchange rates, with changes in the fair value of the interest rate swaps and/or cross currency swaps.

**Cash flow hedges**

Hedges of interest rate risk

Santander UK manages its exposure to the variability in cash flows of floating rate assets and liabilities attributable to movements in market interest rates by entering into interest rate swaps. The interest rate risk component is determined with reference to the underlying benchmark rate attributable to the floating rates asset or liability. Designated benchmark rates referenced are currently SONIA or BoE base rate. Effectiveness is assessed by comparing changes in the fair value of the interest rate swap with changes in the fair value of the hedged item attributable to the hedged risk, applying a hypothetical derivative method using linear regression techniques.

Hedges of foreign currency risk

As Santander UK obtains funding in international markets, we assume significant foreign currency risk exposure, mainly in USD and EUR. In addition, Santander UK also holds debt securities for liquidity purposes which assumes foreign currency exposure, principally in JPY.

Santander UK manages the exposures to the variability in cash flows of foreign currency denominated assets and liabilities to movements in foreign exchange rates by entering into either foreign exchange contracts (spot, forward and swaps) or cross currency swaps. These instruments are entered into to match the cash flow profile and maturity of the estimated interest and principal repayments of the hedged item.

The foreign currency risk component is the change in cash flows of the foreign currency debt arising from changes in the relevant foreign currency forward exchange rate. Such changes constitute a significant component of the overall changes in cash flows of the instrument. Effectiveness is assessed by comparing changes in the fair value of the foreign exchange contracts (spot, forward and swaps) or cross currency swaps with changes in the fair value of the hedged debt attributable to the hedged risk applying a hypothetical derivative method using linear regression techniques.

**IBOR Reform**

Note 41 includes details of the notional value of hedging instruments by benchmark interest rate impacted by IBOR reform and the notional amounts of assets, liabilities and off-balance sheet commitments affected by IBOR reform that have yet to transition to an alternative benchmark interest rate.

**Possible sources of hedge ineffectiveness**

For both fair value and cash flow hedges, hedge ineffectiveness can arise from hedging derivatives with a non-zero fair value at the date of initial designation. In addition, for:

Fair value hedges

Hedge ineffectiveness can also arise due to differences in discounting between the hedged item and the hedging instrument as cash collateralised swaps discount using Overnight Indexed Swaps discount curves not applied to the hedged item; and where counterparty credit risk impacts the fair value of the derivative but not the hedged item. For portfolio hedges of interest rate risk, it can also arise due to differences in the expected and actual volume of prepayments.

Cash flow hedges

Hedge ineffectiveness can also arise due to differences in the timing of cash flows between the hedged item and the hedging instrument. For micro hedges of interest rate risk, it can also arise due to differences in the basis of cash flows between the hedged item and the hedging instrument.

For the Santander UK group, other financial assets at FVTPL comprised £16m (2021: £12m) of financial assets designated at FVTPL and £113m (2021: £173m) of financial assets mandatorily held at FVTPL.

Loans and advances to customers principally represented other loans, being a portfolio of roll-up mortgages. These are managed, and have their performance evaluated, on a fair value basis in accordance with a documented investment strategy, and information about them is provided on that basis to management. Since 2009, the Santander UK group's policy has been not to designate similar new loans at FVTPL.

The net loss in the year attributable to changes in credit risk for loans and advances at FVTPL was £1m (2021: £nil, 2020: £nil). The cumulative net loss attributable to changes in credit risk for loans and advances at FVTPL at 31 December 2022 was £3m (2021: £2m).

At 31 December 2022 and 2021, the Company had no finance lease and hire purchase contract receivables. The Santander UK group enters into finance leasing arrangements primarily for the financing of motor vehicles and a range of assets for its corporate customers. Included in the carrying value of net investment in finance leases and hire purchase contracts is £1,761m (2021: £1,510m) of unguaranteed RV at the end of the current lease terms, which is expected to be recovered through re-payment, re-financing or sale. Contingent rent income of £nil (2021: £nil, 2020: £nil) was earned in the year, which was classified in 'Interest and similar income'. Finance income on the net investment in finance leases was £230m (2021: £243m, 2020: £308m).

Finance lease receivable balances are secured over the asset leased. The Santander UK group is not permitted to sell or repledge the asset in the absence of default by the lessee. The Directors consider that the carrying amount of the finance lease receivables approximates to their fair value.

Included within loans and advances to customers are advances assigned to bankruptcy remote structured entities and Abbey Covered Bonds LLP. These loans provide security to issues of covered bonds and mortgage-backed or other asset-backed securities issued by the Santander UK group. For more, see Note 14.

At 31 December 2022 and 2021, the Santander UK group had contracted with lessees for the following future undiscounted minimum lease payments receivable under operating leases.

14. SECURITISATIONS AND COVERED BONDS

The information in this Note relates to securitisations and covered bonds for consolidated structured entities, used to obtain funding or collateral. It excludes structured entities relating to credit protection transactions.

The Santander UK group uses structured entities to securitise some of the mortgage and other loans to customers that it originates. The Santander UK group also issues covered bonds, which are guaranteed by, and secured against, a pool of the Santander UK group's mortgage loans transferred to Abbey Covered Bonds LLP. The Santander UK group issues mortgage-backed securities, other asset-backed securities and covered bonds mainly in order to obtain diverse, low-cost funding, but also to use as collateral for raising funds via third party bilateral secured funding transactions or for liquidity purposes in the future. The Santander UK group has successfully used bilateral secured transactions as an additional form of medium-term funding; this has allowed the Santander UK group to further diversify its medium-term funding investor base.

Loans and advances to customers include portfolios of residential mortgage loans, and receivables derived from credit agreements with retail customers for the purchases of financed vehicles, which are subject to non-recourse finance arrangements. These loans and receivables have been purchased by, or assigned to, structured entities or Abbey Covered Bonds LLP, and have been funded primarily through the issue of mortgage-backed securities, other asset-backed securities or covered bonds. No gain or loss has been recognised as a result of these sales. The structured entities and Abbey Covered Bonds LLP are consolidated as subsidiary undertakings. The Company and its subsidiaries do not own directly, or indirectly, any of the share capital of any of the structured entities.

**a) Securitisations** 

**i) Master trust structures**

The Santander UK group makes use of master trust structures, whereby a pool of residential mortgage loans is assigned to a trust company by the asset originator. A funding entity acquires a beneficial interest in the pool of assets held by the trust company with funds borrowed from qualifying structured entities, which at the same time issue asset-backed securities to third-party investors or the Santander UK group.

Santander UK plc and its subsidiaries receive payments from the securitisation companies in respect of fees for administering the loans, and payment of deferred consideration for the sale of the loans. Santander UK plc and its subsidiaries have no right or obligation to repurchase any securitised loan, except if certain representations and warranties given by Santander UK plc or its subsidiaries at the time of transfer are breached and, in certain cases, if there is a product switch or further advance, if a securitised loan is in arrears for over two months or if a securitised loan does not comply with regulatory requirements.

**ii) Other securitisation structures** 

The Santander UK group also makes use of auto loan securitisations, whereby a pool of auto loans originated by a member of the Santander UK group is sold to a special purpose vehicle by the asset originator. The special purpose vehicle funds the purchase of the auto loans by issuing asset-backed securities to third-party investors. A proportion of the securities are also retained by members of the Santander UK group. Members of the Santander UK group also receive payments from the special purpose vehicle in respect of fees for administering the auto loans, and payment of deferred consideration for the sale of the auto loans. The seller has no right or obligation to repurchase any securitised loan, except if certain representations and warranties given by the seller at the time of transfer are breached and, in certain cases, if there has been a subsequent variation in the terms of the underlying auto loan not permitted under the sale agreement.

**b) Covered bonds**

Santander UK plc also issues covered bonds, which are its direct, unsecured and unconditional obligation. The covered bonds benefit from a guarantee from Abbey Covered Bonds LLP. Santander UK plc makes a term advance to Abbey Covered Bonds LLP equal to the sterling proceeds of each issue of covered bonds. Abbey Covered Bonds LLP uses the proceeds of the term advance to purchase portfolios of residential mortgage loans and their security from Santander UK plc. Under the terms of the guarantee, Abbey Covered Bonds LLP has agreed to pay an amount equal to the guaranteed amounts when the same shall become due for payment, but which would otherwise be unpaid by Santander UK plc.

**c) Analysis of securitisations and covered bonds**

The Santander UK group's principal securitisation programmes and covered bond programme, together with the balances of the advances subject to securitisation (or for the covered bond programme assigned) and the carrying value of the notes in issue at 31 December 2022 and 2021 are listed below.

In 2021 all the remaining Langton bonds were redeemed and all the remaining associated mortgages were repurchased by Santander UK plc. There was no gain or loss on redemption.

Redemptions for Auto ABS UK Loans, which were held in PSA Finance UK Limited (PSA), are included up to 30 July 2021, the date on which the Santander UK group sold its entire shareholding in PSA.

Holmes Funding Ltd has a beneficial interest of £0.8bn (2021: £0.5bn) in the residential mortgage loans held by Holmes Trustees Ltd. The remaining share of the beneficial interest in residential mortgage loans held by Holmes Trustees Ltd belongs to Santander UK plc.

Fosse Funding (No.1) Ltd has a beneficial interest of £1.5bn (2021: £1.6bn) in the residential mortgage loans held by Fosse Trustee (UK) Ltd. The remaining share of the beneficial interest in residential mortgage loans held by Fosse Trustee (UK) Ltd belongs to Santander UK plc.

The Holmes securitisation companies have cash deposits of £112m (2021: £60m), which have been accumulated to finance the redemption of a number of securities issued by the Holmes securitisation companies. The share of Holmes Funding Ltd in the trust assets is therefore reduced by this amount.

The Fosse securitisation companies have cash deposits of £108m (2021: £185m), which have been accumulated to finance the redemption of a number of securities issued by Fosse securitisation companies. The share of Fosse Funding (No.1) Ltd's beneficial interest in the assets held by Fosse Trustee (UK) Ltd is therefore reduced by this amount.

15. TRANSFERS OF FINANCIAL ASSETS NOT QUALIFYING FOR DERECOGNITION

The Santander UK group enters into transactions in the normal course of business by which it transfers recognised financial assets directly to third parties or to structured entities. These transfers may give rise to the full or partial derecognition of those financial assets. Transferred financial assets that do not qualify for derecognition consist of (i) securities held by counterparties as collateral under repurchase agreements, (ii) securities lent under securities lending agreements, and (iii) loans that have been securitised under arrangements by which the Santander UK group retains a continuing involvement in such transferred assets.

As a result of these sale and repurchase and securities lending transactions, the Santander UK group is unable to use, sell or pledge the transferred assets for the duration of the transaction. The Santander UK group remains exposed to interest rate risk and credit risk on these pledged instruments. The counterparty's recourse is not limited to the transferred assets.

The Santander UK group securitisation transfers do not qualify for derecognition. The Santander UK group remains exposed to credit risks arising from the mortgage loans or credit agreements and has retained control of the transferred assets. Circumstances in which the Santander UK group has continuing involvement in the transferred assets may include retention of servicing rights over the transferred assets (the servicing fee in respect of which is dependent on the amount or timing of the cash flows collected from, or the non-performance of, the transferred assets), entering into a derivative transaction with the securitisation vehicle, retaining an interest in the securitisation vehicle or providing a cash reserve fund. Where the Santander UK group has continuing involvement, it continues to recognise the transferred assets to the extent of its continuing involvement and recognises an associated liability. The net carrying amount of the transferred assets and associated liabilities reflects the rights and obligations that the Santander UK group has retained.

The following table analyses the carrying amount of financial assets that did not qualify for derecognition and their associated financial liabilities:

**Interests in consolidated structured entities**

Structured entities are formed by Santander UK to accomplish specific and well-defined objectives. Santander UK consolidated these structured entities when the substance of the relationship indicates control, as described in Note 1. In addition to the structured entities disclosed in Note14 which are used for securitisation and covered bond programmes, the only other structured entities consolidated by Santander UK are described below. All the external assets and liabilities in these entities are included in the financial statements and ion relevant notes. Other than as set out below, no significant judgements were required with respect to control or significant influence.

Motor Securities 2018-1 Designated Activity Company (Motor 2018)

Motor 2018 is a credit protection entity, and a Designated Activity Company limited by shares, incorporated in Ireland. It has issued a series of credit linked notes varying in seniority which reference portfolios of Santander UK group loans. Concurrently, these entity sells credit protection to Santander UK in respect of the referenced loans and, in return for a fee, is liable to make protection payments to Santander UK upon the occurrence of a credit event in relation to any of the referenced loans. Motor 2018 is consolidated as Santander UK holds a variable interest by retaining the junior tranche of notes issued by the entity.

**b) Interests in joint ventures** 

Santander UK does not have any individually material interests in joint ventures. In 2022, Santander UK's share in the profit after tax of its joint ventures was £36m (2021: £22m) before elimination of transactions between Santander UK and the joint ventures. At 31 December 2022, the carrying amount of Santander UK's interest was £252m (2021: £201m). At 31 December 2022 and 2021, the joint ventures had no commitments and contingent liabilities.

**c) Interests in unconsolidated structured entities**

**Structured entities sponsored by the Santander UK group**

Santander UK has interests in structured entities which it sponsors but does not control. Santander UK considers itself a sponsor of structured entity when it facilitates the establishment of the structured entity. Other than as set out below, no significant judgements were required with respect to control or significant influence.The structured entities sponsored but not consolidated by Santander UK are as follows:

i) Santander (UK) Common Investment Fund (the Fund)

The Fund is a common investment fund that was established to hold the assets of the Santander (UK) Group Pension Scheme. The Fund is not consolidated by Santander UK, but its assets of £8,646m (2021: £14,100m) are accounted for as part of the defined benefit assets and obligations recognised on Santander UK's balance sheet. For more on the Fund, see Note 30. As the Fund holds the assets of the pension scheme, it is outside the scope of IFRS 10. Santander UK's maximum exposure to loss is the carrying amount of the assets held.

ii) Credit protection entities

Santander UK has established four (2021: three) unconsolidated credit protection entities, which are Designated Activity Companies limited by shares, incorporated in Ireland. Each entity has issued a series of credit linked notes varying in seniority which reference portfolios of Santander UK group loans. Concurrently, these entities sell credit protection to Santander UK in respect of the referenced loans and, in return for a fee, are liable to make protection payments to Santander UK upon the occurrence of a credit event in relation to any of the referenced loans. Senior credit linked notes, which amounted to £180m (2021: £1,184m), are issued to, and held by, Santander UK. Junior credit linked notes, which amounted to £465m (2021: £619m), are all held by third party investors and suffer losses incurred in the referenced portfolios after any tranche of risk that has been assumed by Santander UK. Funds raised by the sale of the credit linked notes are deposited with Santander UK as collateral for the credit protection.

The senior credit linked notes, along with the deposits and associated guarantees, are presented on a net basis, to reflect a legal right of set-off between the principal amounts of senior notes and the cash deposits. Deposits and associated guarantees in respect of the junior credit linked notes are included in 'Deposits by customers' (see Note 23). The entities are not consolidated by Santander UK because the third-party investors have the exposure, or rights, to all of the variability of returns from the performance of the entities. No assets are transferred to, or income received from, these entities. Since the credit linked notes (including those held by Santander UK) are fully cash collateralised, Santander UK's maximum exposure to loss is equal to any unamortised fees paid to the entities in connection with the credit protection outlined above.

**Structured entities not sponsored by the Santander UK group**

Santander UK also has interests in structured entities which it does not sponsor or control. These consist of holdings of mortgage and other asset backed securities issued by entities that were established and/or sponsored by other unrelated financial institutions. These securities comprise the asset backed securities included in Note 17. Management has concluded that the Santander UK group has no control or significant influence over these entities and that the carrying value of the interests held in these entities represents the maximum exposure to loss.

**Impairment of goodwill**

In 2022 and 2021, no significant impairment of goodwill was recognised. Goodwill is tested for impairment annually at 31 December, with a review for impairment indicators at 30 June. Goodwill is tested for impairment if reviews identify an impairment indicator or when events or changes in circumstances dictate.

The annual review identified that the risks of Covid-19 have reduced significantly; however rising inflation, exacerbated by the conflict in Ukraine, places increasing uncertainty on the UK economic trajectory, and its potential impact on the carrying value of goodwill as impairment indicators for all cash-generating units (CGUs). As a result, management updated the impairment test at 31 December 2022 for all CGUs.

Basis of the recoverable amount

The recoverable amount of all CGUs was determined based on its value in use (VIU) methodology at each testing date. For each CGU, the VIU is calculated by discounting management's cash flow projections for the CGU. The cash flow projections also take account of increased internal capital allocations needed to achieve internal and regulatory capital targets including the leverage ratio. The key assumptions used in the VIU calculation for each CGU are set out below. The Retail Banking segment consists of the Private Banking CGU and the rest of Retail Banking, known as the Personal Financial Services CGU.

*Carrying amount of Goodwill by CGU and key assumptions in the VIU calculation*

| Personal Financial Services | **1169** | 1169 | **16.6** | 13.6 | **1.6** | 1.6 |
| Private Banking | **30** | 30 | **15.3** | 16.3 | **1.6** | 1.6 |
| Other | **—** | 4 |  | 13.6 |  | 1.6 |
|  | **1199** | 1203 |  |  |  |  |

---

The CGUs do not carry on their balance sheets any other intangible assets with indefinite useful lives.

*Management's judgement in estimating the cash flows of a CGU*

The cash flow projections for the purpose of impairment testing for each CGU are derived from the latest 3-year plan presented to the Board. The Board challenges and endorses management's planning assumptions in light of internal capital allocations needed to support Santander UK's strategy, current market conditions and the macroeconomic outlook. For the goodwill impairment tests conducted at 31 December 2022, the determination of the carrying amount of the Personal Financial Services CGU was based on an allocation of regulatory capital and management's cash flow projections until the end of 2025. The assumptions included in the cash flow projections reflect an allocation to the cost of capital to support future growth, as well as the expected impact of recent events in the UK economic environment on the financial outlook within which the CGUs operate. The cash flow projections are supported by Santander UK's base case economic scenario. For more on the base case economic scenario, including our forecasting approach and the assumptions in place at 31 December 2022, see the Credit risk – Santander UK group level section of the Risk review. The cash flow projections take into account the likely impact of recent changes to the BoE Bank Rate, inflation and also consider the impact of future climate change.

Cash flow projections for the purpose of impairment testing do not take account of any adverse outcomes arising from contingent liabilities (see Note 31), whose existence will be confirmed by uncertain future events or where any obligation is not probable or otherwise cannot be measured reliably, nor do they take account of the benefits arising from Santander UK's transformation plans that had not yet been implemented or committed at 31 December 2022.

*Discount rate*

The rate used to discount the cash flows is based on the cost of equity assigned to each CGU, which is derived using a capital asset pricing model (CAPM) and calculated on a post-tax basis. The CAPM depends on a number of inputs reflecting financial and economic variables, including the risk-free rate and a premium to reflect the inherent risk of the business being evaluated. These variables are based on the market's assessment of the economic variables and management's judgement. The inputs to the CAPM are observable on a post-tax basis. In determining the discount rate, management have identified the cost of equity associated with market participants that closely resemble our CGUs and adjusted them for tax to arrive at the pre-tax equivalent rate. The Private Banking CGU has a different discount rate compared to the Personal Financial Services CGU because different market participants closely resemble each CGU.

*Growth rate beyond initial cash flow projections*

The growth rate for periods beyond the initial cash flow projections is used to extrapolate the cash flows in perpetuity because of the long-term perspective of CGUs. In line with the accounting requirements, management uses the UK Government's official estimate of UK long-term average GDP growth rate, as this is lower than management's estimate of the long-term average growth rate of the business. The estimated UK long-term average GDP growth rate has regard to the long-term impact of inherent uncertainties, such as Brexit, climate change and higher living costs, driven by high inflation and rising interest rates.

Goodwill arising on the acquisition of Personal Financial Services and Private Banking

The VIU of each CGU remains higher than the carrying value of the related goodwill. The VIU review at 31 December 2022 did not indicate the need for an impairment in the Company's goodwill balances. Management considered the level of headroom and the uncertainty relating to the respective estimates of the VIU for those CGUs but determined that there was a sufficient basis to conclude that no impairment was required.

Sensitivities of key assumptions in calculating the value in use

At 31 December 2022 and 31 December 2021, the VIU of the Personal Financial Services CGU was sensitive to reasonably possible changes in the key assumptions supporting the recoverable amount.

The table below presents a summary of the key assumptions underlying the most sensitive inputs to the model for the Personal Financial Services CGU, the key risks associated with each and details of a reasonably possible change in assumptions, such as a decrease in mortgage new business. The sensitivity analysis presented below has been prepared on the basis that a change in each key assumption would not have a consequential impact on other assumptions used in the impairment review. However, due to the interrelationships between some of the assumptions, a change in one of the assumptions might impact one or more of the other assumptions and could result in a larger or smaller overall impact.

The VIU calculation is not sensitive overall to the UK long-term average GDP growth rate assumption given the amount of headroom as the increased profit after tax generated by growth of the business is mostly offset by the need to retain more profit to meet increased regulatory capital requirements driven by the growth in assets. No reasonably possible change in the growth rate assumption would have resulted in an impairment.

*Reasonably possible changes in key assumptions*

---

| | | | | |
|:---|:---|:---|:---|:---|
| CGU | Input | Key assumptions | Associated risks | Reasonably possible change |
| Personal Financial Services | Cash flow projections | –BoE Bank Rate<br>–UK house price growth<br>–UK mortgage loan market growth<br>–UK unemployment rate<br>–Position in the market<br>–Regulatory capital levels. | –Uncertain market outlook<br>–Higher interest rate environment impact on customer affordability<br>–Customer remediation and regulatory action outcomes<br>–Uncertain regulatory capital requirements. | –Cash flow projections decrease by 5% (2021: 5%). |
| Personal Financial Services | Discount rate | –Discount rate used is a reasonable estimate of a suitable market rate for the profile of the business. | –Market rates of interest rise. | –Discount rate increases by 100 basis points (2021: 100 basis points). |

---

At 31 December 2022 and 31 December 2021, a reasonably possible change in the key assumptions in relation to the VIU calculation for the goodwill balance in the Personal Financial Services CGU would have resulted in a reduction in headroom as follows.

---

| | | | |
|:---|:---|:---|:---|
| | | Reduction in headroom | Reduction in headroom |
| | | **2022** | 2021 |
| CGU | Reasonably possible change | **£m** | £m |
| Personal Financial Services | Cash flow projections decrease by 5% (2021: 5%) | **(538)** | (455) |
|  | Discount rate increases by 100 basis points (2021: 100 basis points) | **(887)** | (943) |

---

*Sensitivity of Value in use changes to current assumptions to achieve nil headroom*

Although there was no impairment of goodwill relating to the Personal Financial Services CGU or the Private Banking CGU at 31 December 2022, the test for the Personal Financial Services CGU remains sensitive to some of the assumptions used, as described above. In addition, the changes in assumptions detailed below for the discount rate and cash flow projections would eliminate the current headroom. As a result, there is a risk of impairment in the future should business performance or economic factors diverge from forecasts.

In 2022, there was an increase in headroom arising from an increase in profitability and cash flows forecast as interest rates have risen, alongside a reduction in the required leverage capital requirement, which was partially offset by an increase in the discount rate.

The sensitivity analysis presented below has been prepared on the basis that a change in each key assumption would not have a consequential impact on other assumptions used in the impairment review. However, due to the interrelationships between some of the assumptions, a change in one of the assumptions might impact one or more of the other assumptions and could result in a larger or smaller overall impact.

In 2021, we sold our current head office site in Triton Square, London to a wholly-owned subsidiary of Banco Santander SA. Property, office fixtures and equipment and right-of-use assets were impaired in the period as a result of our multi-year transformation project. The impairment relates to leasehold properties within the scope of our branch network restructuring programme and head office sites which are either closing or consolidating.

As part of our plan to be the best bank to work for in the UK, we are building a new head office in Milton Keynes to meet the flexible needs of a modern workforce. It represents a planned investment of more than £200m, funded from existing resources. Site works began in Q1 2020 with practical completion expected in April 2023. Expenditure at 31 December 2022 was approximately £204m.

For the Santander UK group all (2021: all) of the other financial liabilities at FVTPL were designated as such.

Collateral and associated financial guarantees in the table above represent collateral received, together with associated credit protection guarantees, in respect of the proceeds of the retained senior tranches of credit linked notes described in Note 19.

Gains and losses arising from changes in the credit spread of securities issued by the Santander UK group reverse over the contractual life of the debt, provided that the debt is not repaid at a premium or a discount. The net gain during the year attributable to changes in the Santander UK group's own credit risk on the above securities was £25m (2021: £12m loss, 2020: £3m loss). The cumulative net gain attributable to changes in the Santander UK group's own credit risk on the above securities at 31 December 2022 was £15m (2021: £10m loss, 2020: £3m loss).

At 31 December 2022, the amount that would be required to be contractually paid at maturity of the securities above was £138m higher (2021: £nil) higher than the carrying value.

In 2022, the Santander UK group repurchased certain debt securities and subordinated liabilities as part of ongoing liability management exercises, resulting in a loss of £5m (2021: a loss of £1m).

The above securities will, in the event of the winding up of the issuer, be subordinated to the claims of depositors and all other creditors of the issuer, other than creditors whose claims rank equally with, or are junior to, the claims of the holders of the subordinated liabilities. The subordination amongst each of the subordinated liabilities upon a winding up of the issuer is specified in their respective terms and conditions.

In 2022 and 2021, the Santander UK group had no defaults of principal, interest or other breaches with respect to its subordinated liabilities. No repayment or purchase by the issuer of the subordinated liabilities may be made prior to their stated maturity without the consent of the PRA.

**a) Customer remediation**

Provisions of £77m were recognised in 2022 for two customer remediation exercises relating to our historical mortgage book. Most of the provision relates to the proposed refund of early repayment charges paid by a specific group of customers who historically switched mortgage products The provision remains subject to change as additional data becomes available and remediation boundaries are finalised.

At 31 December 2022 there was no customer remediation provision (2021: £6m) for a systems-related historical issue identified by Santander UK, relating to compliance with certain requirements of the Consumer Credit Act (CCA). The remediation is now complete with all customers having been contacted.

**b) Litigation and other regulatory**

Litigation and other regulatory provisions principally comprised amounts in respect of litigation and other regulatory charges, operational loss and operational risk provisions, and related expenses. A number of uncertainties exist with respect to these provisions given the uncertainties inherent in litigation and other regulatory matters, that affect the amount and timing of any potential outflows with respect to which provisions have been established. These provisions are reviewed at least quarterly. The majority of the 2022 charge is the settlement of a financial penalty of £108m with the FCA for shortcomings in our anti-money laundering controls.

Although the deadline for bringing PPI complaints has passed, customers can still commence Plevin related litigation. Amounts include a provision of £24m for the best estimate of any obligation to pay compensation in respect of current stock and estimated future claims. There are ongoing factual issues to be resolved regarding such litigation which may have legal consequences including the volume and quality of future litigation claims. As a result, the extent of the potential liability and amount of any compensation to be paid remains uncertain.

The balance also included an amount in respect of our best estimate of the liability relating to a legal dispute regarding allocation of responsibility for a specific PPI portfolio of complaints, further described in Note 31. No further information on the best estimate is provided on the basis that it would be seriously prejudicial.

**c) Bank Levy**

A rate of 0.10% applied for 2022 (2021: 0.10%).

**d) Property**

Property provisions include leasehold vacant property provisions, dilapidation provisions for leased properties within the scope of IFRS 16 and decommissioning and disposal costs relating to vacant freehold properties. Leasehold vacant property provisions are made by reference to an estimate of any expected sub-let income, compared to the head rent, and the possibility of disposing of Santander UK's interest in the lease, taking into account conditions in the property market.

**e) ECL on undrawn facilities and guarantees**

Provisions include expected credit losses relating to guarantees given to third parties and undrawn loan commitments.

**f) Restructuring** 

Restructuring provisions relate to severance costs associated with transformation and organisational changes. The provision includes a charge of £19m as part of our multi-year transformation programme to improve future returns, focused on simplifying, digitising and automating the bank.

**g) Other**

Other provisions do not fit into any of the other categories, such as some categories of operational losses, including fraud losses. In 2022, Other provisions included charges for operational risk provisions of £186m, including fraud losses of £153m.

**a) Defined contribution pension plans**

The majority of employees are members of a defined contribution Master Trust, LifeSight. This is the plan into which eligible employees are enrolled automatically. The assets of LifeSight are held in separate trustee-administered funds. Funds arising from Additional Voluntary Contributions (AVCs) are largely held within the main defined benefit scheme operated by the Santander UK group.

An expense of £60m (2021: £64m) was recognised for defined contribution plans in the period and is included in staff costs within operating expenses (see Note 6).

**b) Defined benefit pension schemes**

The Santander UK group operates a number of defined benefit pension schemes. The main scheme is the Santander (UK) Group Pension Scheme (the Scheme). It comprises seven legally segregated sections. The Scheme covers 10% (2021: 11%) of the Santander UK group's current employees and is a funded defined benefit scheme which is closed to new members.

The corporate trustee of the Scheme is Santander (UK) Group Pension Scheme Trustees Limited (the Trustee), a private limited company incorporated in 1996 and a wholly owned subsidiary of Santander UK Group Holdings plc. The principal duty of the Trustee is to act in the best interests of the members of the Scheme. The Trustee board comprises six (2021:five) Directors selected by Santander UK Group Holdings plc, plus four (2021: five) member-nominated Directors selected from eligible members who apply for the role.

The assets of the funded schemes including the Scheme are held independently of the Santander UK group's assets in separate trustee administered funds. Investment strategy across the sections of the Scheme remains under regular review. Investment decisions are delegated by the Trustee to a common investment fund, managed by Santander (CF Trustee) Limited, a private limited company owned by ten Trustee directors, who are the same as the directors of the Trustee. The Santander (CF Trustee) Limited directors' principal duty, within the investment powers delegated to them, is to act in the best interest of the members of the Scheme. Ultimate responsibility for investment policy and strategy rests with the Trustee of the Scheme who is required under the Pensions Act 2004 to prepare a statement of investment principles. The defined benefit pension schemes expose the Santander UK group to risks such as investment risk, interest rate risk, longevity risk and inflation risk. The Santander UK group does not hold any insurance policies over the defined benefit pension schemes and has not entered into any significant transactions with them.

Formal actuarial valuations of the assets and liabilities of the defined benefit schemes are carried out on at least a triennial basis by independent professionally qualified actuaries and valued for accounting purposes at each balance sheet date. The Scheme Trustee is responsible for the actuarial valuations and in doing so considers, or relies in part on, a report of a third-party expert. The latest formal actuarial valuation for the Scheme at 31 March 2022 was finalised in November 2022, with an overall scheme deficit of £183m. The next scheduled triennial funding valuation will be at 31 March 2025. Any funding surpluses can be recovered by Santander UK plc from the Scheme through refunds as the Scheme is run off over time or could be used to pay for the cost of benefits which are accruing.

The main differences between the assumptions used for assessing the defined benefit liabilities for the funding valuation and those used for IAS 19 are that the financial and demographic assumptions used for the funding valuation are generally more prudent than those used for the IAS 19 valuation.

**Valuation techniques**

The main methods for measuring the fair value of the Scheme's assets at 31 December 2022 and 2021 are set out below.

A.The asset valuation is provided by the asset manager. The valuation is based on observable market data, and where relevant is typically based on bid price values, or the single price if only one price is available.

B.The underlying asset valuations are prepared by an independent expert, adjusted for any cash movements where necessary since the latest valuation.

C.Assets are valued by reference to the latest manager statements provided by the managers, adjusted for any cash movements since the latest valuation.

D.Assets relating to insured liabilities are valued by the actuaries based on our year-end accounting assumptions.

The 'Other' category includes hedge fund investments.

A number of insurance transactions have been entered into that have been included in the asset valuation under annuities and Longevity swap. The transactions were as follows:.

–In May 2020 a pensioner buy-in was entered into by the Trustee. This transaction insured 100% of the SMA section pensioner liabilities and 50% of the SPI section pensioner liabilities based on membership in the Scheme at 31 December 2018.

–In March 2021, the Trustee entered into a longevity swap. Approximately 85% of pensioner liabilities were covered by the longevity swap at inception, excluding pensioners in the SMA and SPI sections.

–In 2022, a pensioner buy-in was entered into by the Trustee covering pensioners in the SMA and SPI sections who were uninsured at 30 June 2021.

–In July 2022, the Trustee entered into a second longevity swap, extending the insurance over uninsured pensioners in the same membership groups covered by the first swap transacted in March 2021, based on membership in the Scheme at 31 December 2021.

At 31 December 2022, as highlighted above, the Scheme was invested in certain assets whose values are not based on market observable data, such as the investments in unquoted equities and bonds, as well as property, infrastructure and hedge funds. The valuation of these assets relies on unobservable data as these assets do not have a readily available quoted price in an active market. A large proportion of the property is directly held and valued using a bespoke valuation method taking both the nature of the properties and the tenancy schedules as inputs to derive the fair value. Where there is a time lag between the net asset value and the balance sheet date, management adjusts the value of the assets for any cash movements. Due diligence has been conducted to ensure the values obtained in respect of these assets are appropriate and represent fair value. Given the nature of these investments, we are unable to prepare sensitivities on how their values could vary as market conditions or other variables change.

A strategy is in place to manage interest rate and inflation risk relating to the liabilities. The Scheme prior to 31 December 2022 invested in equities and had an equity collar in place to manage equity risk. The Scheme also hedges a proportion of its foreign exchange exposure to manage currency risk. At 31 December 2022 the equity collar had a notional value of £3m (2021: £1,259m) and the currency forwards had a notional value of £985m (2021: £2,296m). Significant asset de-risking took place in 2022, with the Scheme divesting entirely from listed equities, as well as its multi-asset funds. Significant investments were made in quoted corporate bonds over the year, largely funded from these sales. The sale proceeds also went to de-leveraging the asset portfolio. The Trustee has established the Sustainability Committee which is responsible for overseeing the Scheme's policies, regulatory obligations and priorities in respect of climate change and wider Environmental, Social and Governance (ESG) related matters. This includes the monitoring of climate change related risks and opportunities, scenario analysis and monitoring of investments from an ESG perspective.

The Santander UK group's pension schemes did not directly hold any equity securities of the Company or any of its related parties at 31 December 2022 and 2021. The Santander UK group's pension scheme assets do not include any property or other assets that are occupied or used by the Santander UK group.

The Santander UK group's employee pension funds recognise the magnitude of the challenges that climate and energy transition pose to governments, companies and civil society. They are also aware of their impact on the ability to comply with their fiduciary duty providing long-term risk-adjusted returns to their members. They have committed to a target of net zero by 2050, showing their full support for the Santander UK group's vision, commitment to sustainability and climate change.

**Funding**

In November 2022, in compliance with the Pensions Act 2004, the Trustee and the Santander UK group agreed to a new recovery plan in respect of the Scheme and a schedule of contributions following the finalisation of the 31 March 2022 actuarial valuation. The funding target for this actuarial valuation is for the Scheme to have sufficient assets to make payments to members in respect of the accrued benefits as and when they fall due. In accordance with the terms of the Trustee agreement in place at the time, the Santander UK group contributed £218m in 2022 (2021: £241m) to the Scheme, of which £178m (2021: £194m) was in respect of agreed deficit repair contributions. The agreed schedule of the Santander UK group's contributions to the Scheme covers the period up to 31 March 2026 and comprises of contingent contributions which become due if the funding position of any section falls behind the agreed plan. The Santander UK group also meets Scheme administration expenses. The funding valuation is used to judge the amount of cash contributions the Santander UK group needs to put into the pension scheme. It will always be different to the IAS 19 accounting deficit, which is an accounting rule concerning employee benefits and shown on the balance sheet of our financial statements.

**Actuarial assumptions**

The principal actuarial assumptions used for the Scheme were:

---

|:---|:---|:---|:---|
| | Group | Group | Group |
| | **2022** | 2021 | 2020 |

| –General price inflation | **3.1** | 3.4 | 3.0 |

| Longevity at 60 for future pensioners currently aged 40, on the valuation date: |  |  |  |
| –Males | **28.9** | 29.0 | 29.0 |
| –Females | **31.6** | 31.6 | 31.5 |

---

(1) The discount rate and inflation related assumptions set out in the table above reflect the assumptions calculated based on the Scheme's duration and cash flow profile as a whole. The actual

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;assumptions used were determined for each section independently based on each section's duration and cash flow profile.

**Discount rate for scheme liabilities**

The rate used to discount the retirement benefit obligation for accounting purposes is based on the annual yield at the balance sheet date of high-quality corporate bonds on that date. There are only a limited number of higher quality Sterling-denominated corporate bonds, particularly those that are longer-dated. Therefore, in order to set a suitable discount rate, we need to construct a corporate bond yield curve. In 2022, management updated the model used to construct the curve following a review of the Scheme's IAS 19 assumptions. The model which we use to construct the curve uses corporate bond data but excludes convertible bonds, asset-backed bonds and government related bonds. The curve is then constructed from this data by extrapolating the spot rates from 30 years to 50 years by holding the spread above nominal gilt spot rates constant. From 50 years onwards, it is assumed that spot rates remain constant. When considering an appropriate assumption, we project forward the expected cash flows of each section of the Scheme and adopt a single equivalent cash flow weighted discount rate for each section, subject to management judgement.

**General price inflation**

Consistent with our discount rate methodology, we set the inflation assumption using the expected cash flows for each section of the Scheme, fitting them to an inflation curve to give a weighted average inflation assumption. We then deduct an inflation risk premium to reflect the compensation holders of fixed rate instruments expect to receive for taking on the inflation risk. This premium is subject to a cap, to better reflect management's view of inflation expectations. In 2022, management refined the general price inflation assumption following a review of the Scheme's IAS 19 assumptions, to reflect a different data set and different methodology used to construct the curve.

**General salary increase**

From 1 March 2015, a cap on pensionable pay increases of 1% each year was applied to staff in the Scheme.

**Expected rate of pension increase**

The pension increase assumption methodology uses a stochastic model, which is calibrated to consider both the observed historical volatility term structure and derivative pricing. The model allows for the likelihood that high or low inflation in one-year feeds into inflation remaining high or low in the next year.

**Mortality assumptions**

The mortality assumptions are based on an independent analysis of the Scheme's actual mortality experience, carried out as part of the triennial actuarial valuation, together with recent evidence from the Continuous Mortality Investigation. An allowance is then made for expected future improvements to life expectancy based on the Continuous Mortality Investigation Tables. Following this review the S3 Medium all pensioner mortality table was adopted with appropriate adjustments to reflect the actual mortality experience. For future improvements, at 31 December 2022 the CMI 2021 projection model was adopted, with model parameters selected having had regard to the Scheme's membership profile with an initial addition to improvements of 0.25%per annum, together with a long-term rate of future improvements to life expectancy of 1.25% for male and female members. No weight was placed on the 2020 data in the model, reflecting the uncertainty regarding whether, and how much, 2020 mortality data reflects likely future experience. A modest weight of 10% was placed on the 2021 data in the model, reflecting the likelihood of sustained indirect impacts of the pandemic. Both the mortality table and the projection model are published by the Continuous Mortality Investigation.

In 2022, the methodology for setting the demographic assumptions was changed to better represent current expectations, following a review carried out by the Trustee as part of the 2022 triennial valuation. These reviews resulted in changes in the assumptions for family statistics, early retirement and the withdrawal assumption.

**Actuarial assumption sensitivities**

The sensitivity analyses below have been determined based on reasonably possible changes of the respective assumptions occurring at the end of the reporting period, while holding all other assumptions constant.

---

| | | | | |
|:---|:---|:---|:---|:---|
| | Change in pension obligation at year end from | Change in pension obligation at year end from | (Decrease)/increase | (Decrease)/increase |
| | **2022** | 2021 | **2022** | 2021 |
| Assumption |  |  | £m | £m |
| Discount rate | 50 bps increase  | 25 bps increase | **(501)** | (571) |
| General price inflation | 50 bps increase  | 25 bps increase | **374** | 392 |
| Mortality | Each additional year of longevity assumed | Each additional year of longevity assumed | **203** | 478 |

---

The 50bps sensitivity to the inflation assumption includes the corresponding impact of changes in future pension increase assumptions before and after retirement. The sensitivity analysis presented above may not be representative of the actual change in the defined benefit obligation as it is unlikely that the changes in assumptions would occur in isolation of one another as some of the assumptions may be correlated. Furthermore, in presenting the sensitivity analysis, the present value of the defined benefit obligation has been calculated using the projected unit credit method at the end of the reporting period, which is the same method used to calculate the defined benefit obligation recognised in the balance sheet. There were no changes in the methods and assumptions used in preparing the sensitivity analyses from prior years.

The benefits expected to be paid in each of the next five years, and in the aggregate for the five years thereafter are:

---

| | |
|:---|:---|
| Year ending 31 December | £m |
| 2023 | **416** |
| 2024 | **360** |
| 2025 | **382** |
| 2026 | **404** |
| 2027 | **425** |
| Five years ending 2032 | **2325** |

---

The average duration of the defined benefit obligation at 31 December 2022 was 14.2 years (2021: 18.3 years).

**Emerging risks**

Actions taken in 2022 to reduce asset risk, in line with the agreements already in place with the Trustee, served to improve the Scheme's resilience to market volatility. In 2022, the risks considered in relation to Covid-19 related mainly to the suitability of our long-term mortality assumption for our IAS 19 and funding valuations.

The focus in 2022 shifted to the risks arising from the conflict in Ukraine, rising interest rates, the 2022 actuarial valuation, together with market volatility driven by the UK political landscape. The Santander UK group has collaborated with the Trustee to identify and monitor such risks and ensure they were adequately managed.

31. CONTINGENT LIABILITIES AND COMMITMENTS

---

| | | |
|:---|:---|:---|
| | | Group |
| | **2022** | 2021 |
| | **£m** | £m |
| Guarantees given to third parties | **448** | 363 |
| Formal standby facilities, credit lines and other commitments | **31388** | 37346 |
|  | **31836** | 37709 |

---

At 31 December 2022, the Santander UK group had credit impairment loss provisions relating to guarantees given to third parties and undrawn loan commitments. See Note 29 for more details.

Where the items set out below can be reliably estimated, they are disclosed in the table above.

**Capital support arrangements**

At 31 December 2022, Santander UK plc, Cater Allen Limited, Santander ISA Managers Limited and certain other non-regulated subsidiaries of Santander UK plc were party to a capital support deed entered into on 17 December 2021 and effective from 1 January 2022 (the RFB Sub-Group Capital Support Deed). These parties were permitted by the PRA to form a core UK group as defined in the PRA Rulebook, a permission which expires on 31 December 2024. Exposures of each of the regulated entities to other members of the core UK group are exempt from large exposure limits that would otherwise apply and these exposures are risk-weighted at 0%. Where applicable this permission also provides for intra-group exposures to be excluded from the leverage exposure measure. The purpose of the RFB Sub-Group Capital Support Deed is to facilitate the prompt transfer of available capital resources from, or repayment of liabilities by, the non-regulated parties to any of the regulated parties in the event that one of the regulated parties breached or was at risk of breaching its capital resources or risk concentrations requirements.

**Liquidity support arrangements**

Under the PRA's liquidity rules, Santander UK plc and its subsidiary Cater Allen Limited form the RFB Domestic Liquidity Sub-group (the RFB DoLSub), which allows the entities to collectively meet regulatory requirements for the purpose of managing liquidity risk. Each member of the RFB DoLSub will support the other by transferring surplus liquidity in times of stress.

**Guarantees given to third parties**

Guarantees given to third parties consist primarily of letters of credit, bonds and guarantees granted as part of normal product facilities which are offered to customers.

**Formal standby facilities, credit lines and other commitments**

Ongoing assessments are made to ensure that credit limits remain appropriate considering any change in the security value or the customer's financial circumstances. For unsecured overdraft facilities and credit cards, the facilities are granted based on new business risk assessment and are reviewed more frequently based on internal, as well as external data. Corporate facilities can comprise standby and revolving facilities which are subject to ongoing compliance with covenants and may require the provision of agreed security.

**FSCS**

The FSCS is the UK's independent statutory compensation fund for customers of authorised financial services firms and pays compensation if a firm is unable to pay certain claims against it. The FSCS is funded by levies on the industry and recoveries and borrowings where appropriate.

**Loan representations and warranties** 

In connection with the securitisations and covered bond transactions described in Note 14, the Santander UK group entities selling the relevant loans into the applicable securitisation or covered bond portfolios make representations and warranties with respect to such loans, in each case as of the date of the sale of the loans into the applicable portfolio. These representations and warranties cover, among other things, the ownership of the loan by the relevant Santander UK group entity, absence of a material breach or default by the relevant borrower under the loan, the loan's compliance with applicable laws and absence of material disputes with respect to the relevant borrower, asset and loan. The specific representations and warranties made by Santander UK group companies which act as sellers of loans in these securitisations and covered bond transactions depend in each case on the nature of the transaction and the requirements of the transaction structure. In addition, market conditions and credit rating agency requirements may affect the representations and warranties required of the relevant Santander UK group companies in these transactions.

In the event that there is a material breach of the representations and warranties given by Santander UK plc as seller of loans under the residential mortgage-backed securitisations or the covered bond programmes included in Note 14, or if such representations and warranties prove to be materially untrue at the date when they were given (being the sale date of the relevant mortgage loans), Santander UK plc may be required to repurchase the affected mortgage loans (generally at their outstanding principal balance plus accrued interest). These securitisations and covered bond programmes are collateralised by prime residential mortgage loans. Santander UK plc is principally a retail prime lender and has no appetite or product offering for any type of sub-prime business. In addition, Santander UK plc's credit policy explicitly prohibits such lending.

Similarly, under the auto loan securitisations in Note 14, in the event that there is a breach or inaccuracy in respect of a representation or warranty relating to the loans, the relevant Santander UK group entity who sold the auto loans into the securitisation portfolio will be required to repurchase such loans from the structure (also at their outstanding principal balance plus accrued interest). In addition to breaches of representation and warranties, under the auto loan securitisations, the seller may also have a repurchase obligation if certain portfolio limits are breached (which include, amongst other things, limits as to the size of a loan given to an individual customer, LTV ratio, average term to maturity and average seasoning).

In the case of a repurchase of a loan from the relevant securitisation or covered bond programmes, the Santander UK group may bear any subsequent credit loss on such loan. The Santander UK group manages and monitors its securitisation and covered bond activities closely to minimise potential claims.

**Other legal actions and regulatory matters**

Santander UK engages in discussion, and co-operates, with the FCA, PRA, CMA and other regulators and government agencies in various jurisdictions in their supervision and review of Santander UK including reviews exercised under statutory powers, regarding its interaction with past and present customers, both as part of general thematic work and in relation to specific products, services and activities. During the ordinary course of business, Santander UK is also subject to complaints and threatened legal proceedings brought by or on behalf of current or former employees, customers, investors or other third parties, in addition to legal and regulatory reviews, challenges and tax or enforcement investigations or proceedings in various jurisdictions. All such matters are assessed periodically to determine the likelihood of Santander UK incurring a liability.

In those instances where it is concluded that it is not yet probable that a quantifiable payment will be made, for example because the facts are unclear or further time is required to fully assess the merits of the case or to reasonably quantify the expected payment, no provision is made. In addition, where it is not currently practicable to estimate the possible financial effect of these matters, no provision is made.

FCA civil regulatory investigation into Santander UK plc financial crime systems, processes and controls, and compliance with the Money Laundering Regulations 2007

In December 2022, we paid a £108m financial penalty to settle the FCA's enforcement investigation into the anti-money laundering systems and controls in our Business Banking division in the period between 31 December 2012 and 18 October 2017. The settlement concluded the FCA's investigation.

Payment Protection Insurance

In relation to a specific PPI portfolio of complaints, a legal dispute regarding allocation of liability is in its early stages. The dispute relates to the liability for PPI mis-selling complaints relating to pre-2005 PPI policies underwritten by AXA France IARD and AXA France Vie (together, AXA France - previously Financial Insurance Company Ltd and Financial Assurance Company Ltd respectively) and involves Santander Cards UK Limited (a former GE Capital Corporation entity and distributor of pre-2005 PPI known as GE Capital Bank Limited which was acquired by Banco Santander SA in 2008 and subsequently transferred to Santander UK plc) and a Banco Santander SA subsidiary Santander Insurance Services UK Limited (together the Santander Entities). During the relevant period, AXA France were owned by Genworth Financial International Holdings, Inc (Genworth).

In September 2015, AXA SA acquired AXA France from Genworth. In July 2017, the Santander Entities notified AXA France that they did not accept liability for losses on PPI policies relating to the relevant period. Santander UK plc entered into a Complaints Handling Agreement (CHA) with AXA France pursuant to which it agreed to handle complaints on their behalf, and AXA France agreed to pay redress assessed to be due to relevant policyholders on a without prejudice basis. A standstill agreement was entered into between the Santander Entities and AXA France as a condition of the CHA.

In July 2020, Genworth announced that it had agreed to pay AXA SA circa £624m in respect of PPI mis-selling losses in settlement of the related dispute concerning obligations under the sale and purchase agreement pursuant to which Genworth sold AXA France to AXA SA. The CHA between Santander UK plc and AXA France terminated on 26 December 2020. On 30 December 2020, AXA France provided written notice to the Santander Entities to terminate the standstill agreement. During 2021, AXA France commenced litigation against the Santander Entities seeking recovery of £636m and any further losses relating to pre-2005 PPI. Judgment in respect of the Santander Entities application for AXA France's claim to be struck out/summarily dismissed, was handed down by the Commercial Court on 12 July 2022. In summary, the Commercial Court upheld a significant part of the Santander Entities' strike-out application, striking out AXA France's claim for contribution against Santander for alleged losses and requiring AXA France to re-plead a significant portion of its other pleadings. AXA France updated the amount of losses claimed from £636m to £670m in their Amended Particulars of Claim dated 21 October 2022. Overall, the dispute remains at an early stage and there are ongoing factual issues to be resolved which may have legal consequences including in relation to liability. These issues create uncertainties which mean that it is difficult to reliably predict the outcome or the timing of the resolution of the matter. The litigation and other regulatory provision in Note 29 includes our best estimate of the Santander Entities' liability to the specific portfolio. Further information has not been provided on the basis that it would be seriously prejudicial to the Santander Entities' interests in connection with the dispute.

In addition, and in relation to PPI more generally the PPI provision includes an amount relating to legal claims challenging the FCA's industry guidance on the treatment of Plevin / recurring non-disclosure assessments. This provision is based on current stock levels, future projected claims, and average redress. There remains a risk that volumes received in future may be higher than forecast. The provision in Note 29 includes our best estimate of Santander UK's liability for the specific issue. The actual cost of customer compensation could differ from the amount provided. It is not currently practicable to provide an estimate of the risk and amount of any further financial impact.

German dividend tax arbitrage transactions

In June 2018 the Cologne Criminal Prosecution Office and the German Federal Tax Office commenced an investigation in relation to the historical involvement of Santander UK plc, Santander Financial Services plc and Cater Allen International Limited (all subsidiaries of Santander UK Group Holdings plc) in German dividend tax arbitrage transactions (known as cum/ex transactions). These transactions allegedly exploited a loophole of a specific German settlement mechanism through short-selling and complex derivative structuring which resulted in the German government either refunding withholding tax where such tax had not been paid or refunding it more than once. The German authorities are investigating numerous institutions and individuals in connection with alleged transactions and practices which may be found to be illegal under German law.

During 2022 we continued to cooperate with the German authorities and, with the assistance of external experts, to progress an internal investigation into the matters in question. From Santander UK plc's perspective, the investigation is focused principally on the period 2009-2011 and remains on-going. There remain factual issues to be resolved which may have legal consequences including potentially material financial penalties. These issues create uncertainties which mean that it is difficult to predict the resolution of the matter including timing or the significance of the possible impact. These uncertainties mean it is not currently possible to make a reliable assessment of the size of any related potential liability. Any potential losses, claims or expenses suffered or incurred by Santander Financial Services plc in respect of these matters have been fully indemnified by Santander UK plc, as part of the ring-fencing transfer scheme between Santander UK plc, Santander Financial Services plc and Banco Santander SA.

Taxation

The Santander UK group engages in discussion, and co-operates, with HM Revenue & Customs (HMRC) in their oversight of the Santander UK group's tax matters. The Santander UK group adopted the UK's Code of Practice on Taxation for Banks in 2010.

Certain leases in which the Santander UK group is or was the lessor have been under review by HMRC in connection with claims for tax allowances. Under the terms of the lease agreements, the Santander UK group is fully indemnified in all material respects by the respective lessees for any liability arising from the disallowance of tax allowances plus accrued interest. During 2021, an outline agreement in principle in respect of a number of these lease arrangements was reached directly between the lessee and HMRC. This agreement was executed in April 2022, resulting in a final payment by the lessee to HMRC and the conclusion of HMRC's review. There is no financial impact for the Santander UK group.

Other

On 2 November 2015, Visa Europe Ltd agreed to sell 100% of its share capital to Visa Inc. The deal closed on 21 June 2016. As a member and shareholder of Visa Europe Ltd, Santander UK received upfront consideration made up of cash and convertible preferred stock. Conversion of the preferred stock into Class A Common Stock of Visa Inc. depends on the outcome of litigation against Visa involving UK & Ireland (UK&I) multilateral interchange fees (MIFs). Following ring-fencing, all Visa stock is now held by Santander Equity Investments Limited (SEIL), outside the ring-fenced bank.

In addition, Santander UK and certain other UK&I banks have agreed to indemnify Visa Inc. in the event that the preferred stock is insufficient to meet the costs of this litigation. Visa Inc. has recourse to this indemnity once more than €1bn of losses relating to UK&I MIFs have arisen or once the total value of the preferred stock issued to UK&I banks on closing has been reduced to nil. Whilst Santander UK's liability under this indemnity is capped at €39.85m, Visa Inc. may have recourse to a general indemnity in place under Visa Europe Operating Regulations for damages not satisfied through the above mechanism. At this stage, it is unclear whether the litigation will give rise to more than €1bn of losses relating to UK&I MIFs which means it is difficult to predict the resolution of the matter including the timing or the significance of the possible impact.

As part of the sale of subsidiaries, businesses and other entities, and as is normal in such circumstances, Santander UK plc (and/or, where relevant, its subsidiaries) has given warranties and indemnities to the purchasers.

**Obligations under stock borrowing and lending agreements**

Obligations under stock borrowing and lending agreements represent contractual commitments to return stock borrowed. These obligations are offset by a contractual right to receive stock under other contractual agreements. See Note 35.

**Other off-balance sheet commitments**

The Santander UK group has commitments to lend at fixed interest rates which expose us to interest rate risk. For more, see the Risk review.

**Step-up Callable Perpetual Reserve Capital Instruments** 

During 2022, the £300m Step-up Callable Perpetual Reserve Capital Instruments were called for value on 14 February 2022 and redeemed at their principal amount.

**AT1 securities**

The AT1 securities issued by the Company were subscribed for by its immediate parent company, Santander UK Group Holdings plc. The AT1 securities are perpetual and pay a quarterly distribution. At each distribution payment date, the Company can decide whether to pay the distribution, which is non-cumulative, in whole or in part. The distribution rate resets every five years. The securities will be automatically written down and the investors will lose their entire investment in the securities should the CET1 capital ratio of the Santander UK prudential consolidation group, or the Company (calculated on a solo basis), fall below 7%.

All AT1 securities are redeemable at the option of the Company, and only with the consent of the PRA.

In June 2022, Santander UK plc purchased and redeemed the £750m 7.375% Perpetual Capital Securities and issued £750m 6.50% Perpetual Capital Securities, which were fully subscribed by the Company's immediate parent company, Santander UK Group Holdings plc.

(1) Dividends paid have been restated for 2021 from the £1,494m previously disclosed to £1,505m due to an administrative error.

(2) Issue and Repurchase of other equity instruments and Other Equity Instrument Other changes have been restated for 2021 from £450m, £500m and £50m previously disclosed to £210m for both Issue and Repurchase of Other equity instrument and £nil for Other changes due to an administrative error.

**Footnotes to the consolidated cash flow statement**

Net cash flows from operating activities includes interest received of £6,508m (2021: £4,806m, 2020: £5,139m), interest paid of £2,089m (2021: £1,064m, 2020: £1,857m) and dividends received of £nil (2021: £nil, 2020: £nil).

Total cash outflow for leases was £28m (2021: £28m, 2020: £48m).

**Restatements in the consolidated cash flow statement**

The presentation of the consolidated cash flow statement has changed to present 'profit before tax' within cash flows from operating activities instead of 'profit after tax'. Prior periods have been restated. As a result, for the year ended 31 December 2021 and 31 December 2020, the adjustment for 'corporation tax charge' in 'non-cash items included in profit' within cash flows from operating activities has been decreased by £504m and £134m respectively.

Following a decision by the IFRS Interpretations Committee in April 2022, Santander UK updated its accounting policy to exclude from cash and cash equivalents Reserves Collateralisation Accounts (RCAs) balances held at the BoE relating to Santander UK's participation in certain payments schemes. Instead, RCAs balances are classified as restricted balances and included within 'change in operating assets' in the cash flow statement. Prior periods have been restated. As a result, opening cash and cash equivalents at 1 January 2022 and 1 January 2021 have been restated by £1,580m and £985m respectively. At 31 December 2021, cash and cash equivalents were reduced by £1,580m and restricted balances were increased by £1,580m. At 31 December 2020, cash and cash equivalents were reduced by £985m and restricted balances were increased by £985m. The net change in cash and balances at central banks was restated as a result of a decrease in cash inflows from operating activities of £595m in 2021(2020: increase of £95m).

**Other matters**

In addition, in 2021, there was a disposal of non-controlling interests of £181m.

The Santander UK group provides assets as collateral in the following areas of the business.

**Sale and repurchase agreements**

The Santander UK group also enters into sale and repurchase agreements and similar transactions of debt securities. Upon entering into such transactions, the Santander UK group provides collateral in excess of the borrowed amount. The carrying amount of assets that were so provided at 31 December 2022 was £11,553m (2021: £15,368m), of which £900m (2021: £639m) was classified within 'Loans and advances to customers – securitisations and covered bonds' in the table above.

**Securitisations and covered bonds**

As described in Note 14, Santander UK plc and certain of its subsidiaries issue securitisations and covered bonds. At 31 December 2022, there were £24,984m (2021: £20,199m) of gross assets in these secured programmes and £829m (2021: £767m) of these related to internally retained issuances that were available for use as collateral for liquidity purposes in the future.

At 31 December 2022, a total of £1,725m (2021: £1,855m) of notes issued under securitisation and covered bond programmes had been retained internally, a proportion of which had been used as collateral via third party bilateral secured funding transactions, which totalled £500m at 31 December 2022 (2021: £500m), or for use as collateral for liquidity purposes in the future.

**Stock borrowing and lending agreements** 

Asset balances under stock borrowing and lending agreements represent stock lent by the Santander UK group. These balances amounted to £34,861m at 31 December 2022 (2021: £45,936m) and are offset by contractual commitments to return stock borrowed or cash received.

**Derivatives business** 

In addition to the arrangements described above, collateral is also provided in the normal course of derivative business to counterparties. At 31 December 2022 £1,506m (2021: £1,947m) of such collateral in the form of cash had been provided by the Santander UK group and is included in the table.

**b) Collateral accepted as security for assets**

The collateral held as security for assets, analysed between those liabilities accounted for on balance sheet and off-balance sheet, was:

---

| | | |
|:---|:---|:---|
| | Group | Group |
| | **2022** | 2021 |

| **Total on-balance sheet** | **1741** | 931 |
| **Total off-balance sheet** | **10141** | 17781 |

---

**Purchase and resale agreements** 

The Santander UK group also enters into purchase and resale agreements and similar transactions of debt securities. Upon entering into such transactions, the Santander UK group receives collateral in excess of the loan amount. The level of collateral held is monitored daily and if required, further calls are made to ensure the market values of collateral remains at least equal to the loan balance. The subsidiaries are permitted to sell or repledge the collateral held in the absence of default. At 31 December 2022, the fair value of such collateral received was £8,628m (2021: £14,562m). Of the collateral received, almost all was sold or repledged. The subsidiaries have an obligation to return collateral that they have sold or pledged.

**Stock borrowing and lending agreements**

Obligations representing contractual commitments to return stock borrowed by the Santander UK group amounted to £1,513m at 31 December 2022 (2021: £3,219m) and are offset by a contractual right to receive stock lent.

**Derivatives business**

In addition to the arrangements described, collateral is also received from counterparties in the normal course of derivative business. At 31 December 2022, £1,741m (2021: £931m) of such collateral in the form of cash had been received by the Santander UK group and is included in the table.

**Lending activities**

In addition to the collateral held as security for assets, the Santander UK group may obtain a charge over a customer's property in connection with its lending activities. Details of these arrangements are set out in the 'Credit risk' section of the Risk review.

36. SHARE-BASED COMPENSATION

The Santander UK group operates share schemes and arrangements for eligible employees. The main current schemes are the Sharesave Schemes, the Deferred Shares Bonus Plan, the Partnership Shares scheme and the Transformation Incentive Plan. All share options and awards relate to shares in Banco Santander SA.

The amount charged to the income statement in respect of share-based payment transactions is set out in Note 6.

At 31 December 2022, the carrying amount of liabilities arising from share-based payment transactions, excluding any cash element was £6.6m (2021: £3.7m), of which £0.1m had vested at 31 December 2022 (2021: £0.4m).

**a) Sharesave Schemes**

The Santander UK group launched its fifteenth HM Revenue & Customs approved Sharesave invitation under Banco Santander SA sponsorship in September 2022. Sharesave invitations have been offered since 2008 under broadly similar terms. Under the Sharesave Scheme's HMRC-approved savings limits, eligible employees may enter into contracts to save between £5 and £500 per month. For all schemes, at the end of a fixed term of three or five years after the grant date, the employees can use these savings to buy shares in Banco Santander SA at a discount, calculated in accordance with the rules of the scheme. The option price is calculated as the average middle market quoted price of Banco Santander SA shares over the first three dealing days prior to invitation and discounted by up to 20%. This year a 10% discount was applied. The vesting of awards under the scheme depends on continued employment with the Banco Santander group. Participants in the scheme have six months from the date of vesting to exercise the option.

The table below summarises movements in the number of options, and changes in weighted average exercise price over the same period.

|:---|:---|:---|:---|
| | | | 2021 |
| | **Number of options** | Number of options | Weighted average exercise price |

| Exercisable at 31 December | **3439** | 1321 | 2.75 |

---

The weighted average share price at the date the options were exercised was £2.34 (2021: £2.65).

The following table summarises the range of exercise prices and weighted average remaining contractual life of the options at 31 December 2022 and 2021.

| £4 to £5 | **0** | 1 | 4.02 |

The fair value of each option at the date of grant is estimated using an analytical model that also reflects the correlation between EUR and GBP. This model uses assumptions on the share price, the EUR/GBP FX rate, the EUR/GBP risk-free interest rate, dividend yields, the expected volatilities of both the underlying shares and EUR/GBP for the expected lives of options granted. The weighted average grant-date fair value of options granted during the year was £0.23 (2021: £0.20).

**b) Deferred shares bonus plan**

Deferred bonus awards are designed to align employee performance with shareholder value and encourage increased retention of senior employees. Those employees who are designated as Material Risk Takers receive part of their annual bonus as a deferred award comprising 50% in shares, and 50% in cash. Either 40% (for any variable pay award of less than £500,000) or 60% (for any variable pay award greater than £500,000) is deferred over a four, five or seven year period from the anniversary of the initial award. Deferred bonus awards in shares are subject to an additional one-year retention period from the point of delivery. Any deferred awards are dependent on continued employment and subject to Santander UK's discretion, and the vesting of deferred bonus awards are subject to risk and performance adjustment.

**c) Partnership Shares scheme**

A Partnership Shares scheme is operated for eligible employees under the Share Incentive Plan (SIP) umbrella. Participants can choose to invest up to £1,800 per tax year (or no more than 10% of an employee's salary for the tax year) from pre-tax salary to buy Banco Santander SA shares. Shares are held in trust for the participants. There are no vesting conditions attached to these shares, and no restrictions as to when the shares can be removed from the trust. However, if a participant chooses to sell the shares before the end of five years, they will be liable for the taxable benefit received when the shares are taken out of the trust. The shares can be released from trust after five years free of income tax and national insurance contributions. 3,974,698 shares were outstanding at 31 December 2022 (2021: 3,618,796 shares).

(1)2021 and 2020 salaries and fees have been restated to reflect fees earned in respect of services rendered during the year. Fees of £7,463 have been reallocated from 2021 to 2020.

(2)2021 and 2020 Performance related payments have been restated to account for 36% of Directors and selected KMP awards being subject to long-term metrics. Performance against these metrics can decrease the award to 0% and may not increase the award value. Previously, the value of the Variable Pay Plan awards have been disclosed in full which has resulted in an overstatement post the application of performance conditions. The value of the 2021 and 2020 Variable Pay Plan awards subject to long-term performance conditions will be disclosed after the close of the performance period upon vesting. In addition to the remuneration in the table above, no grants of shares in Banco Santander SA were made to Directors and KMPs as part of buy-outs of deferred performance-related payments in connection with previous employment in 2022 (2021: one to a KMP with a value of £107,225, of which £25,413 vested in the year, 2020: one to a Director of £1,293,678 of which £242,605 vested in the year and one to a KMP of £924,133 of which £60,500 vested in the year). A payment of guaranteed variable remuneration of £660,648 was made to a Director in 2022 (2021: £nil, 2020: £nil) part of which was awarded in Banco Santander SA shares. The element of the guaranteed remuneration which vested in respect of 2022 has been disclosed above, 40%, and the remaining 60% will be disclosed upon vesting.

(3) Compensation for loss of office of £172,856 was paid in 2022 to two Directors (2021: £356,054 for two Directors, 2020: £nil). Compensation for loss of office was paid to three KMPs in 2022 totalling £1,540,400 (2021: £nil , 2020: one KMP: £263,097).

In 2022, the remuneration, excluding pension contributions, of the highest paid Director, was £3,510,441 (2021: £3,740,810, 2020: £2,093,149) of which £1,900,506 (2021: £1,864,320, 2020: £nil) was performance related. In 2022, the accrued defined benefit pension relating to the highest paid director was £nil (2021: £22,119, 2020: £21,309 per annum for a different individual).

**b) Retirement benefits**

Defined benefit pension schemes are provided to certain employees. See Note 30 for details of the schemes and the related costs and obligations. One director has a deferred pension benefit accruing under a defined benefit scheme. Ex gratia pensions paid to former Directors of Santander UK plc in 2022, which have been provided for previously, amounted to £379,945 (2021: £370,668; 2020: £366,248). Since the Company became part of the Banco Santander group, the Board has not awarded any new ex-gratia pensions.

39. FINANCIAL INSTRUMENTS

**a) Fair value measurement and hierarchy**

**(i) Fair value measurement**

The fair value of financial instruments is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal, or in its absence, the most advantageous market to which Santander UK has access at that date. The fair value of a liability reflects its non-performance risk.

**Financial instruments valued using observable market prices**

If a quoted market price in an active market is available for an instrument, the fair value is calculated as the current bid price multiplied by the number of units of the instrument held.

**Financial instruments valued using a valuation technique**

In the absence of a quoted market price in an active market, management uses internal models to make its best estimate of the price that the market would set for that financial instrument. In order to make these estimations, various techniques are employed, including extrapolation from observable market data and observation of similar financial instruments with similar characteristics. Wherever possible, valuation parameters for each product are based on prices directly observable in active markets or that can be derived from directly observable market prices. Chosen valuation techniques incorporate all the factors that market participants would take into account in pricing transactions.

Santander UK manages certain groups of financial assets and liabilities on the basis of its net exposure to either market risks or credit risk. As a result, it has elected to use the exception under IFRS 13 which permits the fair value measurement of a group of financial assets and financial liabilities on the basis of the price that would be received to sell a net long position for a particular risk exposure or paid to transfer a net short position for a particular risk exposure in an orderly transaction between market participants at the measurement date under current market conditions.

**(ii) Fair value hierarchy**

Santander UK applies the following fair value hierarchy that prioritises the inputs to valuation techniques used in measuring fair value. The hierarchy establishes three categories for valuing financial instruments, giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three categories are: quoted prices in active markets (Level 1), internal models based on observable market data (Level 2) and internal models based on other than observable market data (Level 3). If the inputs used to measure an asset or a liability fall to different levels within the hierarchy, the classification of the entire asset or liability will be based on the lowest level input that is significant to the overall fair value measurement of the asset or liability.

Santander UK categorises assets and liabilities measured at fair value within the fair value hierarchy based on the inputs to the valuation techniques as follows:

Level 1&nbsp;&nbsp;&nbsp;&nbsp;Unadjusted quoted prices for identical assets or liabilities in an active market that Santander UK can access at the measurement date. Active markets are assessed by reference to average daily trading volumes in absolute terms and, where applicable, by reference to market capitalisation for the instrument.

Level 2&nbsp;&nbsp;&nbsp;&nbsp;Quoted prices in inactive markets, quoted prices for similar assets or liabilities, recent market transactions, inputs other than quoted market prices for the asset or liability that are observable either directly or indirectly for substantially the full term, and inputs to valuation techniques that are derived principally from or corroborated by observable market data through correlation or other statistical means for substantially the full term of the asset or liability.

Level 3&nbsp;&nbsp;&nbsp;&nbsp;Significant inputs to the pricing or valuation techniques are unobservable. These unobservable inputs reflect the assumptions that market participants would use when pricing assets or liabilities and are considered significant to the overall valuation.

Changes in the observability of significant valuation inputs during the reporting period may result in a transfer of assets and liabilities within the fair value hierarchy. The Santander UK group recognises transfers between levels of the fair value hierarchy when there is a significant change in either its principal market or the level of observability of the inputs to the valuation techniques at the end of the reporting period.

**b) Valuation techniques**

The main valuation techniques employed in internal models to measure the fair value of the financial instruments at 31 December 2022 and 2021 are set out below. In substantially all cases, the principal inputs into these models are derived from observable market data. Santander UK did not make any material changes to the valuation techniques and internal models it used in 2022, 2021 and 2020.

A.In the valuation of financial instruments requiring static hedging (for example interest rate, currency derivatives and property derivatives) and in the valuation of loans and advances and deposits, the 'present value' method is used. Expected future cash flows are discounted using the interest rate curves of the applicable currencies or forward house price index levels, as well as credit spreads. The interest rate curves are generally observable market data and reference yield curves derived from quoted interest rates in appropriate time bandings, which match the timings of the cash flows and maturities of the instruments.

B.In the valuation of equity financial instruments requiring dynamic hedging (principally equity securities, options and other structured instruments), proprietary local volatility and stochastic volatility models are used. These types of models are widely accepted in the financial services industry. Observable market inputs used in these models include the bid-offer spread, foreign currency exchange rates, volatility and correlation between indices. In limited circumstances, other inputs may be used in these models that are based on unobservable market data, such as the Halifax's UK HPI volatility, HPI forward growth, HPI spot rate, mortality and mean reversion.

C.In the valuation of financial instruments exposed to interest rate risk that require either static or dynamic hedging (such as interest rate futures, caps and floors, and options), the present value method (futures), Black's model (caps/floors) and the Hull/White and Markov functional models (Bermudan options) are used. These types of models are widely accepted in the financial services industry. The significant inputs used in these models are observable market data, including appropriate interest rate curves, volatilities, correlations and exchange rates. In limited circumstances, other inputs may be used in these models that are based on unobservable market data, such as HPI volatility, HPI forward growth, HPI spot rate and mortality.

D.In the valuation of linear instruments such as credit risk and fixed-income derivatives, credit risk is measured using dynamic models similar to those used in the measurement of interest rate risk. In the case of non-linear instruments, if the portfolio is exposed to credit risk such as credit derivatives, the probability of default is determined using the credit default spread market. The main inputs used to determine the underlying cost of credit of credit derivatives are quoted credit risk premiums and the correlation between the quoted credit derivatives of various issuers.

The fair values of the financial instruments arising from Santander UK's internal models take into account, among other things, contract terms and observable market data, which include such factors as bid-offer spread, interest rates, credit risk, exchange rates, the quoted market price of equity securities, volatility and prepayments. In all cases, when it is not possible to derive a valuation for a particular feature of an instrument, management uses judgement to determine the fair value of the particular feature. In exercising this judgement, a variety of tools are used including proxy observable data, historical data and extrapolation techniques. Extrapolation techniques take into account behavioural characteristics of equity markets that have been observed over time, and for which there is a strong case to support an expectation of a continuing trend in the future. Estimates are calibrated to observable market prices when they become available.

Santander UK believes its valuation methods are appropriate and consistent with other market participants. Nevertheless, the use of different valuation methods or assumptions, including imprecision in estimating unobservable market inputs, to determine the fair value of certain financial instruments could result in different estimates of fair value at the reporting date and the amount of gain or loss recorded for a particular instrument. Most of the valuation models are not significantly subjective, because they can be tested and, if necessary, recalibrated by the internal calculation of and subsequent comparison to market prices of actively traded securities, where available.

**c) Control framework**

Fair values are subject to a control framework designed to ensure that they are either determined or validated by a function independent of the risk-taker. To this end, ultimate responsibility for the determination of fair values lies with the Risk Department. For all financial instruments where fair values are determined by reference to externally quoted prices or observable pricing inputs to models, independent price determination or verification is utilised. In inactive markets, direct observation of a traded price may not be possible. In these circumstances, Santander UK will source alternative market information to validate the financial instrument's fair value, with greater weight given to information that is considered to be more relevant and reliable.

The factors that are considered in this regard include:

–The extent to which prices may be expected to represent genuine traded or tradeable prices

–The degree of similarity between financial instruments

–The degree of consistency between different sources

–The process followed by the pricing provider to derive the data

–The elapsed time between the date to which the market data relates and the balance sheet date

–The manner in which the data was sourced.

The source of pricing data is considered as part of the process that determines the classification of the level of a financial instrument. Consideration is given to the quality of the information available that provides the current mark-to-model valuation and estimates of how different these valuations could be on an actual trade, taking into consideration how active the market is. For spot assets that cannot be sold due to illiquidity, forward estimates are discounted to estimate a realisable value over time. Adjustments for illiquid positions are regularly reviewed to reflect changing market conditions.

For fair values determined using a valuation model, the control framework may include as applicable, independent development and / or validation of: (i) the logic within the models; (ii) the inputs to those models; and (iii) any adjustments required outside the models. Internal valuation models are validated independently within the Risk Department. A validation report is produced for each model-derived valuation that assesses the mathematical assumptions behind the model, the implementation of the model and its integration within the trading system.

**d) Fair values of financial instruments carried at amortised cost** 

The following tables analyse the fair value of the financial instruments carried at amortised cost at 31 December 2022 and 2021, including their levels in the fair value hierarchy - Level 1, Level 2 and Level 3. It does not include fair value information for financial assets and financial liabilities carried at amortised cost if the carrying amount is a reasonable approximation of fair value. Cash and balances at central banks, which consist of demand deposits with the Bank of England, together with cash in tills and ATMs, have been excluded from the table as the carrying amount is deemed an appropriate approximation of fair value.

The carrying value above of any financial assets and liabilities that are designated as hedged items in a portfolio (or macro) fair value hedge relationship excludes gains and losses attributable to the hedged risk, as this is included as a separate line item on the balance sheet.

**Valuation methodology for financial instruments carried at amortised cost**

The valuation approach to specific categories of financial instruments is described below.

**Assets:**

**Loans and advances to customers**

The approach to estimating the fair value of loans and advances to customers has been determined by discounting expected cash flows to reflect either current market rates or credit spreads relevant to the specific industry of the borrower. The determination of their fair values is an area of considerable estimation and uncertainty as there is no observable market and values are significantly affected by customer behaviour.

i) Advances secured on residential property

The fair value of the mortgage portfolio is calculated by discounting contractual cash flows by different spreads for each LTV Band, after taking account of expected customer prepayment rates. The spread is based on new business interest rates derived from publicly available competitor market information.

ii) Corporate loans

The determination of the fair values of performing loans is calculated by discounting the contractual cash flows and also deducting other costs relating to expected credit losses, cost of capital, credit risk capital, operational risk capital, cost of funding and operating costs.

iii) Other loans

These consist of unsecured personal loans, credit cards, overdrafts and consumer (auto) finance. The weighted average lives of these portfolios are typically short and relate to relatively new business. For unsecured personal loans and consumer (auto) finance loans, a small surplus or deficit has been recognised based on the differential between existing portfolio margins and the current contractual interest rates.

**Loans and advances to banks** 

These comprise secured loans, short-term placements with banks including collateral and unsettled financial transactions. The secured loans have been valued based on a discounted spread for the term of the loans using valuation technique A as described above. The carrying amount of the other items is deemed a reasonable approximation of their fair value, as the transactions are very short-term in duration.

**Reverse repurchase agreements - non-trading**

The fair value of the reverse repurchase agreements - non trading has been estimated using valuation technique A as described above, using a spread appropriate to the underlying collateral.

**Other financial assets at amortised cost**

These consist of asset backed securities and debt securities. The asset backed securities can be complex products and in some instances are valued with the assistance of an independent, specialist valuation firm. These fair values are determined using industry-standard valuation techniques, including discounted cash flow models. The inputs to these models used in these valuation techniques include quotes from market makers, prices of similar assets, adjustments for differences in credit spreads, and additional quantitative and qualitative research. The debt security investments consist of a portfolio of government debt securities. The fair value of this portfolio has been determined using quoted market prices.

**Liabilities:**

**Deposits by customers** 

The majority of deposit liabilities are payable on demand and therefore can be deemed short-term in nature with the fair value equal to the carrying value. Certain of the deposit liabilities are at a fixed rate until maturity. The deficit/surplus of fair value over carrying value of these liabilities has been estimated by reference to the market rates available at the balance sheet date for similar deposit liabilities of similar maturities. The fair value of such deposit liabilities has been estimated using valuation technique A as described above.

**Deposits by banks**

The fair value of deposits by banks, including repos, has been estimated using valuation technique A as described above, discounted at the appropriate credit spread.

**Repurchase agreements - non trading**

The fair value of the repurchase agreements - non trading has been estimated using valuation technique A as described above, discounted at a spread appropriate to the underlying collateral.

**Debt securities in issue and subordinated liabilities**

Where reliable prices are available, the fair value of debt securities in issue and subordinated liabilities has been calculated using quoted market prices. Where reliable prices are not available, internal models have been used to determine fair values, which take into account, among other things, contract terms and observable market data, which include such factors as interest rates, credit risk and exchange rates. In all cases, when it is not possible to derive a valuation for a particular feature of an instrument, management uses judgement to determine the fair value of the particular feature. In exercising this judgement, a variety of tools are used including proxy observable data.

**e) Fair values of financial instruments measured at fair value**

The following tables summarise the fair values of the financial assets and liabilities accounted for at fair value at 31 December 2022 and 31 December 2021, analysed by their levels in the fair value hierarchy - Level 1, Level 2 and Level 3.

**f) Fair value adjustments** 

The internal models incorporate assumptions that Santander UK believes would be made by a market participant to establish fair value. Fair value adjustments are adopted when Santander UK considers that there are additional factors that would be considered by a market participant that are not incorporated in the valuation model.

Santander UK classifies fair value adjustments as either 'risk-related' or 'model-related'. The fair value adjustments form part of the portfolio fair value and are included in the balance sheet values of the product types to which they have been applied. The fair value adjustments are set out in the following table:

---

| | | |
|:---|:---|:---|
| | **2022** | 2021 |
| | **£m** | £m |
| Risk-related: |  |  |
| - Bid-offer and trade specific adjustments | **(12)** | (9) |
| - Uncertainty | **12** | 20 |
| - Credit risk adjustment | **2** | 6 |
| - Funding fair value adjustment | **1** | 3 |
|  | **3** | 20 |
| Day One profit | **1** |  |
|  | **4** | 20 |

---

**Risk-related adjustments**

Risk-related adjustments are driven, in part, by the magnitude of Santander UK's market or credit risk exposure, and by external market factors, such as the size of market spreads.

(i) Bid-offer and trade specific adjustments

Portfolios are marked at bid or offer, as appropriate. Valuation models will typically generate mid-market values. The bid-offer adjustment reflects the cost that would be incurred if substantially all residual net portfolio market risks were closed using available hedging instruments or by disposing of or unwinding the position. For debt securities, the bid-offer spread is based on a market price at an individual security level. For other products, the major risk types are identified. For each risk type, the net portfolio risks are first classified into buckets, and then a bid-offer spread is applied to each risk bucket based upon the market bid-offer spread for the relevant hedging instrument.

(ii) Uncertainty

Certain model inputs may be less readily determinable from market data, and/or the choice of model itself may be more subjective. In these circumstances, a range of possible values exists that the financial instrument or market parameter may assume, and an adjustment may be needed to reflect the likelihood that in estimating the fair value of the financial instrument, market participants would adopt more conservative values for uncertain parameters and/or model assumptions than those used in the valuation model.

(iii) Credit risk adjustment

Credit risk adjustments comprise credit and debit valuation adjustments. The credit valuation adjustment (CVA) is an adjustment to the valuation of OTC derivative contracts to reflect within fair value the possibility that the counterparty may default, and Santander UK may not receive the full market value of the transactions. The debit valuation adjustment (DVA) is an adjustment to the valuation of the OTC derivative contracts to reflect within the fair value the possibility that Santander UK may default, and that Santander UK may not pay full market value of the transactions.

Santander UK calculates a separate CVA and DVA for each Santander UK legal entity, and within each entity for each counterparty to which the entity has exposure. Santander UK calculates the CVA by applying the probability of default of the counterparty to the expected positive exposure to the counterparty, and multiplying the result by the loss expected in the event of default i.e. LGD. Conversely, Santander UK calculates the DVA by applying the PD of the Santander UK group, to the expected positive exposure of the counterparty to Santander UK and multiplying the result by the LGD. Both calculations are performed over the life of the potential exposure.

For most products Santander UK uses a simulation methodology to calculate the expected positive exposure to a counterparty. This incorporates a range of potential exposures across the portfolio of transactions with the counterparty over the life of the portfolio. The simulation methodology includes credit mitigants such as counterparty netting agreements and collateral agreements with the counterparty.

The methodologies do not, in general, account for wrong-way risk. Wrong-way risk arises where the underlying value of the derivative prior to any credit risk adjustment is positively correlated to the probability of default of the counterparty. When there is significant wrong-way risk, a trade-specific approach is applied to reflect the wrong-way risk within the valuation. Exposure to wrong-way risk is limited via internal governance processes and deal pricing. Santander UK considers that an appropriate adjustment to reflect wrong-way risk is £nil (2021: £nil).

(iv) Funding fair value adjustment (FFVA)

The FFVA is an adjustment to the valuation of OTC derivative positions to include the net cost of funding uncollateralised derivative positions. This is calculated by applying a suitable funding cost to the expected future funding exposure of any uncollateralised component of the OTC derivative portfolio.

**Model-related adjustments**

Models used for portfolio valuation purposes may be based upon a simplifying set of assumptions that do not capture all material market characteristics. Additionally, markets evolve, and models that were adequate in the past may require development to capture all material market characteristics in current market conditions. In these circumstances, model limitation adjustments are adopted. As model development progresses, model limitations are addressed within the core revaluation models and a model limitation adjustment is no longer needed.

**Day One profit adjustments**

Day One profit adjustments are adopted where the fair value estimated by a valuation model is based on one or more significant unobservable inputs. Day One profit adjustments are calculated and reported on a portfolio basis.

The timing of recognition of deferred Day One profit and loss is determined individually. It is deferred until either the instrument's fair value can be determined using market observable inputs or is realised through settlement. The financial instrument is subsequently measured at fair value, adjusted for the deferred Day One profit and loss. Subsequent changes in fair value are recognised immediately in the Income Statement without immediate reversal of deferred Day One profits and losses.

**Valuation techniques**

**1. Derivative assets – Equity and credit contracts**

These are valued using a probability weighted set of HPI forward prices, which are assumed to be a reasonable representation of the increase in value of the Santander UK group's reversionary interest portfolio underlying the derivatives. The probability used reflects the likelihood of the homeowner vacating the property and is calculated from mortality rates and acceleration rates which are a function of age and gender, obtained from the relevant mortality tables. Indexing is felt to be appropriate due to the size and geographical dispersion of the reversionary interest portfolio. These are determined using HPI Spot Rates adjusted to reflect estimated forward growth. Non-seasonally adjusted (NSA) national and regional HPI are used in the valuation model to avoid any subjective judgement in the adjustment process, which is made by Markit, which publishes the Halifax House Price Index.

The inputs used to determine the value of the reversionary property derivatives are HPI spot, HPI forward growth and mortality rates. The principal pricing parameter is HPI forward growth.

**2. FVTPL assets – Loans and advances to customers – roll-up mortgage portfolio**

These represent roll-up mortgages (sometimes referred to as lifetime mortgages), which are an equity release scheme under which a property owner takes out a loan secured against their home. The owner does not have to make any interest payments during their lifetime in which case the fixed interest payments are rolled up into the mortgage. The loan or mortgage (capital and rolled-up interest) is repaid upon the owner's vacation of the property and the value of the loan is only repaid from the value of the property. This is known as a 'no negative equity guarantee'. Santander UK suffers a loss if the sale proceeds from the property are insufficient to repay the loan, as it is unable to pursue the homeowner's estate or beneficiaries for the shortfall.

The value of the mortgage 'rolls up' or accretes until the owner vacates the property. In order to value the roll-up mortgages, Santander UK uses a probability-weighted set of European option prices (puts) determined using the Black-Scholes model, in which the 'no negative equity guarantee' are valued as short put options. The probability weighting applied is calculated from mortality rates and acceleration rates as a function of age and gender, taken from mortality tables.

The inputs used to determine the value of these instruments are HPI spot, HPI forward growth, HPI volatility, mortality rates and repayment rates. The principal pricing parameter is HPI forward growth. The HPI forward growth rate used is unobservable and is the same as used in the valuation of Instrument 1 above. The other parameters do not have a significant effect on the value of the instruments.

**3. FVTPL assets – Loans and advances to customers – other loans**

These relate to loans to transport and education companies. The fair value of these loans is estimated using the 'present value' model based on a credit curve derived from current market spreads. Loan specific credit data is unobservable, so a proxy population is applied based on industry sector and credit rating.

**4. FVTPL assets – Debt securities**

These consist of reversionary property securities and are an equity release scheme, where the property owner receives an upfront lump sum in return for paying a fixed percentage of the sales proceeds of the property when the owner vacates the property. These reversionary property securities are valued using a probability-weighted set of HPI forward prices which are assumed to be a reasonable representation of the increase in value of Santander UK's reversionary interest portfolio underlying the derivatives. The probability weighting used reflects the probability of the homeowner vacating the property through death or moving into care and is calculated from mortality rates and acceleration factors which are a function of age and gender, obtained from the relevant mortality table.

The inputs used to determine the value of these instruments are HPI spot, HPI forward growth and mortality rates. The principal pricing parameter is HPI forward growth. Discussion of the HPI spot rate, HPI forward growth rate and mortality rates for this financial instrument is the same as Instrument 1 above. An adjustment is also made to reflect the specific property risk. Specific property risk is from the difference between the specific properties in the portfolio, and the average price as expressed in the regionally weighted house price index.

**5. FVTPL assets – Debt securities (Credit linked notes)**

These consist of the retained senior tranches of credit linked notes in respect of credit protection vehicles sponsored by Santander UK and are mandatorily held at fair value through profit or loss. These vehicles provide credit protection on reference portfolios of Santander UK group loans with junior notes sold to external investors. The notes retained by Santander UK are classified as level 3 financial instruments as their valuation depends upon unobservable parameters relating to the underlying reference portfolios of loans, including credit spreads, correlations and prepayment speed, which have a significant effect on the overall valuation. For more information, see 'Credit protection entities' in Note 19.

**6. FVOCI assets – Loans and advances to customers – other loans**

These relate to shipping loans. The fair value of these loans is estimated using the 'present value' model based on a credit curve derived from current market spreads. Loan specific credit data is unobservable, so a proxy population is applied based on industry sector and credit rating.

**7. Derivative liabilities – Equity contracts**

There are three types of derivatives in this category:

European options – These are valued using a modified Black-Scholes model where the HPI is log-normally distributed with the forward rates determined from the HPI forward growth.

Asian options – Asian (or average value) options are valued using a modified Black-Scholes model, with an amended strike price and volatility assumption to account for the average exercise period, through a closed form adjustment that reflects the strike price relative to the distribution of stock prices at each relevant date. This is also known as the Curran model.

Forward contracts – Forward contracts are valued using a standard forward pricing model.

The inputs used to determine the value of the above instruments are HPI spot rate, HPI forward growth rate and HPI volatility. The principal pricing parameter is HPI forward growth rate, which is unobservable.

**8. FVTPL liabilities – Financial guarantees**

These relate to credit protection guarantees in respect of the proceeds of the retained senior tranches of credit linked notes described in Instrument 5 above and have been designated at fair value through profit or loss. These instruments are valued using the same unobservable parameters described in Instrument 5 above, such that changes in the valuation of the senior tranches of the credit linked notes are offset by changes in the value of these credit protection guarantees. For more information, see 'Credit protection entities' in Note 19.

**Effect of changes in significant unobservable assumptions to reasonably possible alternatives (Level 3)**

As discussed above, the fair value of financial instruments are, in certain circumstances, measured using valuation techniques that incorporate assumptions that are not evidenced by prices from observable current market transactions in the same instrument and are not based on observable market data and, as such require the application of a degree of judgement. Changing one or more of the inputs to the valuation models to reasonably possible alternative assumptions would change the fair values significantly. The following table shows the sensitivity of these fair values to reasonably possible alternative assumptions.

Favourable and unfavourable changes are determined on the basis of changes in the value of the instrument as a result of varying the levels of the unobservable input as described in the table below. The potential effects do not take into effect any hedged positions.

(1)The range of actual assumption values used to calculate the weighted average disclosure.

(2)The HPI spot rate in the weighted average column represents the HPI spot rate index level at 31 December 2022 and 2021.

No sensitivities are presented for FVTPL assets – Debt securities, Credit Linked Notes (instrument 5) and FVTPL liabilities – financial guarantees (instrument 8), as the terms of these instruments are fully matched. As a result, any changes in the valuation of the credit linked notes would be offset by an equal and opposite change in the valuation of the financial guarantees.

As the above table is based on contractual maturities, no account is taken of call features related to subordinated liabilities. In addition, the repayment terms of debt securities may be accelerated in line with relevant covenants. Further, no account is taken of the possible early repayment of Santander UK's mortgage-backed non-recourse finance which is redeemed by Santander UK as funds become available from redemptions of the residential mortgages. Santander UK has no control over the timing and amount of redemptions of residential mortgages.

40. OFFSETTING FINANCIAL ASSETS AND LIABILITIES

The following table shows the impact of netting arrangements on:

–All financial assets and liabilities that are reported net on the balance sheet

–All derivative financial instruments and repurchase agreements and other similar secured lending and borrowing agreements that are subject to enforceable master netting arrangements or similar agreements, but do not qualify for balance sheet netting.

The table identifies the amounts that have been offset in the balance sheet and also those amounts that are covered by enforceable netting arrangements (offsetting arrangements and financial collateral) but do not qualify for netting under the requirements described above.

For derivative contracts, the 'Financial instruments' column identifies financial assets and liabilities that are subject to set off under netting agreements, such as the ISDA Master Agreement or derivative exchange or clearing counterparty agreements, whereby all outstanding transactions with the same counterparty can be offset and close-out netting applied across all outstanding transactions covered by the agreements if an event of default or other predetermined events occur. Financial collateral refers to cash and non-cash collateral obtained, typically daily or weekly, to cover the net exposure between counterparties by enabling the collateral to be realised in an event of default or if other predetermined events occur. For repurchase and reverse repurchase agreements and other similar secured lending and borrowing, the 'Financial instruments' column identifies financial assets and liabilities that are subject to set off under netting agreements, such as global master repurchase agreements and global master securities lending agreements, whereby all outstanding transactions with the same counterparty can be offset and close-out netting applied across all outstanding transactions covered by the agreements if an event of default or other predetermined events occur. Financial collateral typically comprises highly liquid securities which are legally transferred and can be liquidated if a counterparty defaults.

Santander UK engages in a variety of counterparty credit mitigation strategies in addition to netting and collateral arrangements. Therefore, the net amounts presented in the tables below do not purport to represent Santander UK's actual credit exposure.

(1)Financial collateral is reflected at its fair value but has been limited to the net balance sheet exposure so as not to include any over-collateralisation.

(2)This column includes contractual rights of set-off that are subject to uncertainty under the laws of the relevant jurisdiction.

(3)The balance sheet total is the sum of 'Net amounts reported on the balance sheet' that are subject to enforceable netting arrangements and 'Amounts not subject to enforceable netting arrangements'.

(4)The amounts offset within loans and advances to customers/banks or deposits by customers/banks relate to offset mortgages which are classified as either and that are subject to netting.

41. INTEREST RATE BENCHMARK REFORM

**Regulatory announcements**

In March 2021, the FCA and ICE Benchmark Administration (IBA, the administrator of LIBOR) announced that GBP, Euro, Swiss franc and Japanese yen LIBOR settings, as well as settings for 1-week and 2-month US dollar LIBOR, would cease at the end of 2021, with the remaining US dollar LIBOR settings ceasing at the end of June 2023.

To help mitigate the risk of widespread disruption to legacy LIBOR contracts which had not transitioned by the end of 2021, in September 2021 the FCA confirmed its decision to use powers granted under the UK Benchmarks Regulation, to require continued publication using a synthetic methodology for the 1-month, 3-month and 6-month GBP and Japanese yen LIBOR settings until at least the end of 2022.

In September 2022, the FCA announced that for synthetic yen LIBOR setting, market participants should be prepared for publication to cease permanently at the end of 2022. The FCA also announced the continued publication of the 1-month and 6-month synthetic GBP LIBOR settings for a further 3 months after the end of 2022 until 31 March 2023 to support any remaining transition efforts. The FCA has no intention to use its powers to compel IBA to continue to publish the 1- and 6-month synthetic GBP LIBOR settings beyond this date and these settings will permanently cease immediately after their final publication on 31 March 2023.

In November 2022, the FCA proposed to require the IBA to continue to publish the 1-month, 3-month and 6-month US dollar LIBOR settings under an unrepresentative synthetic methodology until the end of September 2024, after which it is expected to cease permanently. For GBP LIBOR, the FCA announced that they intend to continue to require IBA to publish the 3-month synthetic GBP LIBOR setting until the end of March 2024, after which it will cease permanently.

The effect of these announcements and proposals is that the final LIBOR publication would be the end of September 2024:

–the 3 synthetic Japanese yen LIBOR settings ceased at end of December 2022

–the 1-month and 6-month synthetic GBP LIBOR settings will cease at the end of March 2023

–the overnight and 12-month USD LIBOR settings will cease at the end of June 2023

–the 3-month synthetic GBP LIBOR setting will cease at the end of March 2024, and

–the 1-month, 3-month and 6-month synthetic USD LIBOR settings would cease at the end of September 2024 (proposed).

**Amendments to accounting standards**

The IASB amended IFRS 9 'Financial Instruments', IAS 39 'Financial Instruments: Recognition and Measurement' and IFRS 7 'Financial Instruments: Disclosures' in 2019 (the Phase 1 amendments) to provide temporary exceptions to specific hedge accounting requirements because of the uncertainty arising from the reform. The exceptions end at the earlier of when the uncertainty regarding the timing and the amount of interest rate benchmark-based cash flows is no longer present, and discontinuance of the hedge relationship (or reclassification of all amounts from the cash flow hedge reserve). The Phase 1 amendments continue to apply to Santander UK's GBP LIBOR cash flow hedges, for remaining legacy contracts, and USD LIBOR cash flow hedges (but not any using 1-week or 2-month USD LIBOR settings).

The IASB made further amendments to various IFRSs (the Phase 2 amendments) in 2020 to address issues that might affect financial reporting during the reform of an interest rate benchmark, including the effects of changes to contractual cash flows or hedging relationships arising from the replacement of an interest rate benchmark with an alternative benchmark rate. The Phase 2 amendments require entities, as a practical expedient, to account for a change in the basis for determining the contractual cash flows by updating the effective interest rate using the guidance in IFRS 9 resulting in no immediate gain or loss being recognised, as long as the change is directly required by IBOR reform and takes place on an economically equivalent basis. The practical expedient was applied to all instruments or contracts that transitioned to alternative benchmark interest rates during 2022 and had no material impact for the Santander UK group. The Phase 2 amendments also provide additional temporary reliefs from applying specific IAS 39 hedge accounting requirements to hedging relationships directly affected by IBOR reform. For GBP LIBOR cash flow hedges of remaining legacy contracts using 1-month and 6-month synthetic settings, the transition to alternative benchmark interest rates will take place no later than March 2023 and, for those using the 3-month synthetic setting, no later than March 2024. For USD LIBOR cash flow hedges, transition will take place no later than June 2023 for those using overnight and 12-month USD LIBOR settings and no later than September 2024 for those using 1-month, 3-month and 6-month synthetic USD LIBOR settings.

**Managing LIBOR transition**

During 2021, Santander UK along with its customers and counterparties, agreed the transition to alternative reference rates for the majority of agreements referencing the LIBOR settings that ceased at the end of 2021. During 2022, the LIBOR transition project was closed, and local business areas have continued to work with customers and counterparties to further reduce the number of untransitioned agreements, including those referencing synthetic LIBOR and the continuing USD LIBOR settings.

The following tables show the notional amounts of assets, liabilities and off-balance sheet commitments at 31 December 2022 and 31 December 2021 affected by IBOR reform that have yet to transition to an alternative benchmark interest rate.

1. Many of the Santander UK group's derivatives subject to IBOR reform are standard ISDA contracts and are subject to supplementary ISDA fallback provisions which became effective on 25 January 2021.

2. Settings for GBP, JPY & NOK LIBOR & 1-week and 2-month USD LIBOR ceased on 31 December 2021 and for EONIA on 3 January 2022. For certain legacy contracts, while 1-month, 3-month and 6-month settings for JPY LIBOR ceased on 31 December 2022, 1-month and 6-month synthetic GBP LIBOR settings have been extended until the end of March 2023 and until the end of March 2024 for the 3-month synthetic GBP LIBOR setting. Overnight, and 12-month USD LIBOR settings will cease on 30 June 2023. For certain legacy contract, 1-month, 3-month and 6-month synthetic USD LIBOR settings would cease at the end of September 2024.

The following tables show the notional amount of derivatives in hedging relationships directly affected by uncertainties related to IBOR reform.

(1)The 2-month USD LIBOR setting ceased on 31 December 2021. Overnight and 12-month USD LIBOR settings will cease on 30 June 2023. For certain legacy contracts, 1-month, 3-month and 6-month synthetic USD LIBOR settings would cease at the end of September 2024.

The Santander UK group's USD LIBOR cash flow hedges extend beyond the anticipated cessation dates for LIBOR. The Santander UK group expects that USD LIBOR will be replaced by SOFR but there remains uncertainty over the timing and amount of the replacement rate cash flows for USD LIBOR cash flow hedges. Hedging relationships impacted by uncertainty about IBOR reform may experience ineffectiveness due to market participants' expectations of when the shift from the existing IBOR benchmark rate to an alternative benchmark interest rate will occur or because transition of the hedged item and the hedging instrument could occur at different times.

The Santander UK group will cease to apply the assumptions that the hedged benchmark interest rate, the cash flows of the hedged item and/or hedging instrument will not be altered because of IBOR reform when the uncertainty arising from IBOR reform is no longer present. This will require amendment to hedge documentation by the end of the reporting period in which the changes occur. Cumulative changes in the hedged cash flows and the hedging instrument based on new alternative benchmark rates will also be remeasured when IBOR reform uncertainty is removed.

42. DISCONTINUED OPERATIONS AND ASSETS HELD FOR SALE

**Discontinued operations**

**Transfer of the CIB Business**

Santander UK plc transferred a significant part of its CIB business to the London branch of Banco Santander SA under a Part VII banking business transfer scheme, which completed on 11 October 2021. The residual parts of the CIB business were wound down or transferred to other segments. For the periods prior to its sale, the CIB business met the requirements for presentation as discontinued operations.

The financial performance and cash flow information relating to the discontinued operations were as follows:

**For the years ended 31 December**

| | | | |
|:---|:---|:---|:---|
|  | **2022** | 2021 | 2020 |

| Tax on profit from discontinued operations | **—** | (12) | (13) |
| **Profit from discontinued operations after tax** | **—** | 31 | 32 |

---

There were no gains or losses recognised on the measurement to fair value less costs to sell or on the disposal of the asset groups constituting the discontinued operations.

In 2022, the net cash flows attributable to the operating activities in respect of discontinued operations were £nil outflow (2021: £3,612m outflow, 2020: £1,815m outflow). There were no investing or financing activities in respect of discontinued operations.

**Assets held for sale**

**Sale of property**

Management considered the sale of Santander House and Shenley Wood freehold land and buildings, part of an agreement with the developer for the construction of Unity Place, to be highly probable at the balance sheet date. As such, the Santander UK group reclassified these properties, which are included in the Corporate Centre segment and carried at their sales prices, as held for sale. The sale is expected to complete in H2 2023 with no gain or loss.

At 31 December 2022, assets held for sale comprised:

---

|:---|:---|:---|
| | **2022** | 2021 |
| | **£m** | £m |
| **Assets** |  |  |
| Property, plant and equipment | **49** | **—** |
| **Total assets held for sale** | **49** | **—** |

43. EVENTS AFTER THE BALANCE SHEET DATE

There have been no significant events between 31 December 2022 and the date of approval of these financial statements which would require a change to or additional disclosure in the financial statements.

44. NOTES TO THE BALANCE SHEET

**Restatement in the consolidated Balance sheet**

In 2022, the macro hedge of interest rate risk balances increased significantly and are now disclosed separately on the face of the balance sheet rather than being included in Other assets and Other liabilities. Prior periods have been restated accordingly. As a result, at 31 December 2021, £77m (2020: £1,226m) has been reclassified from Other assets into the Macro hedge of interest rate risk asset, and £122m (2020: £188m) has been reclassified from Other liabilities into the Macro hedge of interest rate risk liability.

Risk factors

An investment in Santander UK plc (the Company) and its subsidiaries (us, we or Santander UK) involves a number of risks, the material ones of which are set out below.

**Geopolitical and macro-economic risks**

**The war in Ukraine could materially affect our operations and financial position**

On 24 February 2022, Russia launched a large-scale military action against Ukraine. The Russian military action has caused an ongoing humanitarian crisis in Europe. It has also significantly impacted global commodity and financial markets, leading to supply chain disruptions and increases in the prices of energy, oil, gas and raw materials. This has led to heightened inflation, which has created further challenges for monetary authorities and our customers.

We do not have a presence in Russia and Ukraine and our direct exposure to Russian and Ukrainian markets and assets is negligible. However, the effect of Russia's continued military action against Ukraine on global commodity and financial markets and general macroeconomic conditions remains uncertain, and there is a risk that the economic effects of Russia's continued military action against Ukraine could exacerbate the current slowdown in the global economy, which would adversely affect our businesses, results of operations and financial position.

Price pressures on the energy, oil and gas sectors resulting from the Russian military action against Ukraine underline the need to accelerate the decarbonisation transition and present opportunities to finance new energy solutions that can improve energy security in the medium to long term. However, historic reliance on stable and cheap energy has meant that price pressures on the energy, oil and gas sectors resulting from the Russian military action against Ukraine and the resulting increases in energy prices pose risks to economic growth and debt sustainability, contributing to the challenges our customers are facing in terms of cost of living.

The continuation or escalation of the conflict between Russia and Ukraine, including the extension of the conflict to other countries in the region, could lead to further increases in energy prices (particularly gas prices, if supplies to Europe remain interrupted) and heightened inflationary pressures. This could lead to further increases in interest rates, impact financial market stability in the Eurozone and worsen the current cost of living crisis our customers are facing. Such developments would negatively affect the payment capacity of some of our customers, whose likely need for increased support will place additional pressures on the staff in our financial support and call centres.

In response to the Russian military action against Ukraine, the United States of America (US), the European Union (EU), the United Kingdom (UK) and other UN member states and jurisdictions, have imposed, and may further impose, severe financial and economic sanctions and export controls against Russia, Belarus, the so-called Donetsk People's Republic and the so-called Luhansk People's Republic. Such sanctions have included freezing/blocking assets, targeting major Russian banks, the Russian Central Bank, and certain Russian companies and individuals, imposing export controls against Russia and Russian interests, as well as disconnecting certain Russian banks from the SWIFT system (Society for Worldwide Interbank Financial Telecommunication). In addition, the sanctions imposed also include a ban on trading in sovereign debt and other securities. Russia has implemented certain countermeasures in response. The scale of sanctions is unprecedented, complex and rapidly evolving, and poses continuously increasing operational and compliance risks to Santander UK. Our corporate framework and policies are designed to ensure compliance with applicable laws, regulations and economic sanctions, including US, UK, EU and UN economic sanctions, in the countries in which we operate. Such sanctions and other measures, as well as the existing and potential further responses from Russia or other countries to such sanctions, tensions and military actions, have resulted in an increasingly fragmented macroeconomic, trade and regulatory environment. Currently, we do not have any loans, credits or contingencies affected by the recent sanctions imposed on Russia. However, we cannot predict whether any of the countries in which we operate will enact additional economic sanctions or trade restrictions in response to the Russian military action against Ukraine or the impact such additional sanctions or restrictions may have on us which may include increased costs and regulatory burdens associated with the compliance of the evolving and complex sanctions landscape. The heightened regulatory, political and media focus on our response to this crisis may also increase our exposure to conduct and reputational risks.

Furthermore, the disruption and volatility in the global financial markets caused by the Russian invasion and the potential of further tightening of financial market conditions due to the conflict could have a material adverse effect on Santander UK's ability to access funding, capital and liquidity on financial terms acceptable to it and result in an increase in Santander UK's cost of funding due to widening of credit spreads. This could have a material adverse effect on Santander UK's operations, financial condition and prospects.

In addition, the risk of cyberattacks on companies and institutions could increase as a result of Russia's military action against Ukraine and in response to the consequent sanctions imposed by the US, the EU, the UK and other jurisdictions. Such attacks could adversely affect our ability to maintain or enhance our cyber security and data protection measures. While we continue to see increasing ransomware attacks across sectors driven by supply chain tool compromises, and expect this trend to continue, we have not experienced any notable information or cyber security incidents as a result of Russia's actions against Ukraine. We continue to actively monitor this situation.

**Santander UK's operations, financial condition and prospects are materially impacted by economic conditions in the UK and disruptions in the global economy and global financial markets**

Santander UK's business activities are concentrated in the UK, where it offers a range of banking and financial products and services to UK retail and corporate customers. As a consequence, Santander UK's operations, financial condition and prospects are significantly affected by the general economic conditions in the UK.

Despite the economic recovery experienced during 2021 in the UK as measures to combat the COVID-19 pandemic were eased, pre-pandemic growth levels were not reached. There remains a risk of an extended period of economic contraction that continues through 2023 as the effects of higher bank rates, Brexit, and higher and more persistent inflation continue to affect supply chains and business and household confidence and finances. Interest rates have risen sharply over the course of 2022 and there is a risk that this trend will continue throughout 2023, putting further pressures on household finances due to a sharp rise of the costs for refinancing their mortgage for some of our customers and significantly higher costs of borrowing overall. Higher mortgage rates could dampen demand in the housing market, leading to a drop in new business or a fall in house prices, reducing the value of the collateral we hold against mortgages. These risks could create further downward pressure on the economy; for example: a large surge in business failures with knock-on effects for the labour market resulting in high rates of unemployment that affect the ability of customers to pay their debts, which could also contribute to negative multiplier effects through delayed investment and spending; and a stronger push towards protectionism as governments look to protect home industries. This could also lead to a longer-term turn in the credit cycle with a broader contraction of credit as lenders attempt to protect themselves from increased losses.

In particular, Santander UK faces, among others, the following risks in this period of economic uncertainty (including the effect of those risks on gross domestic product, inflation, unemployment and house prices):

–Reduced demand for Santander UK's products and services - particularly the potential for reduced mortgage market volumes.

–Inability of Santander UK's borrowers to make payments on their loans in full or on time.

–The degree of uncertainty concerning economic conditions may adversely affect the accuracy of Santander UK's estimates, which may, in turn, impact the reliability of the IFRS 9 model and process to determine the sufficiency of Santander UK's loan loss allowances.

–Lower house or other asset prices, reducing the value of collateral Santander UK holds on mortgage and other lending.

–Higher and more persistent inflation, reducing Santander UK's profitability and increasing the cost of living for Santander UK's borrowers.

–The value and liquidity of the portfolio of investment securities that Santander UK holds may be adversely affected.

Santander UK is also exposed to:

–Broader geopolitical issues, which remain heightened with the potential for a further pushback against globalism. Further moves towards unilateralism may also cause increased tension and/or hostilities between nations, which could negatively impact the global economy and financial markets. In addition, Russia's invasion of Ukraine has impacted the UK economy, in particular by pushing up energy and oil prices and increasing inflation further;

–Climate change risks which could result in material damage to our customers' property or businesses or have a material impact on our customers' business models under a transition to a low carbon economy; and

–Social unrest as a result of severe economic disruption.

Adverse changes in the credit quality of Santander UK's borrowers or counterparties or a general deterioration in UK economic conditions could reduce the recoverability and value of Santander UK's assets and require an increase in its level of provisions for expected credit losses. There can be no assurance that Santander UK will not have to increase its provisions for loan losses in the future as a result of increases in non-performing loans or for other reasons beyond its control. Material increases in Santander UK's provision for loan losses and write-off or charge-offs have had and could again have a material adverse effect on its operations, financial condition and prospects. Any significant reduction in the demand for Santander UK products and services, a sustained downturn in the UK economy or changes in central bank interest rates could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Inflation continued to rise in 2022, mainly driven by increasing energy and food prices. Monetary policy in the UK has been tightened significantly since the end of 2021 and there are expectations of further rate increases with a peak rate in 2023. Our own budget forecasts anticipate a gradual fall back in the inflation rate, following a peak in 2022, to meet the target rate by 2026. Economic instability and downturns beyond the UK may also impact the UK economy as a whole. Europe's manufacturing base is heavily dependent upon natural gas, and restriction in supply and significantly increased costs are expected to have a material adverse impact on the Eurozone economy, which could lead to disruption and volatility in the global financial markets, as a result of debt sustainability concerns. This could have a material adverse impact on Santander UK, including Santander UK's ability to access capital and liquidity on financial terms acceptable to Santander UK, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

A recessionary economic environment could also lead to rating downgrades affecting the UK, Santander UK or its customers, investments and/or instruments, causing capital impacts due to increased RWAs, an increase in the volatility of wholesale markets and the cost of funding. Fiscal concerns related to the UK have already increased volatility in UK financial markets which necessitated Bank of England intervention in late September 2022.

**The Covid-19 pandemic**

The Covid-19 pandemic has caused, and the Covid-19 pandemic (or new strains or variations thereof) or unforeseen new diseases or infections have the potential to cause, social disruption and a material economic downturn in the UK and globally. Macroeconomic expectations are that the effects of the Covid-19 pandemic will be long lasting with the level and speed of economic recovery still uncertain, with impacts being felt largely in a tight labour market, supply chain pressures and increased inflation. The Covid-19 pandemic has had a material adverse effect on Santander UK's operations and income and could continue to have a material adverse effect on its operations, income, financial condition and prospects. To the extent that the residual impacts of the Covid-19 pandemic continue to adversely affect the UK or global economy and/or Santander UK, it may also have the effect of increasing the likelihood and/or magnitude of other risks described herein or may pose other risks which are not presently known to Santander UK or not currently expected to be significant to Santander UK's business, operations or financial performance.1

In 2022, certain adverse consequences of the Covid-19 pandemic continued to impact the macroeconomic environment, including labour shortages and disruptions of global supply chains, which contributed to rising inflationary pressures. These adverse consequences may persist for some time. If new Covid-19 waves, or the emergence of another infection of similar proportions, force countries to re-adopt measures that restrict economic activity, the macroeconomic environment could deteriorate and adversely impact our business and results of operations, which could include, but is not limited to (i) a decreased demand for our products and services; (ii) material impairment of our loans and other assets including goodwill; (iii) a decline in the value of collateral; (iv) constraints on our liquidity due to market conditions, exchange rates and customer withdrawal of deposits and continued draws on lines of credit; and (v) downgrades to our credit ratings. Any downgrade in our credit rating would likely increase our cost of funding, require us to post additional collateral or take other actions under some of our derivative and other contracts and adversely affect our interest margins and results of operations.

Moreover, our operations could still be impacted by risks from remote working, which were largely deployed as a response to the Covid-19 pandemic. While in 2022 we continued to implement a partial return to our office locations, we still maintain flexibility to work remotely, and our staff have progressively adapted a hybrid approach to working. If we become unable to successfully operate our business from remote locations including, for example, due to failures of our technology infrastructure and controls, or increased cybersecurity risks, this could result in business disruptions that could have a material and adverse effect on our business.

**The UK's withdrawal from the European Union (Brexit) could have a material adverse effect on Santander UK's operations, financial condition and prospects**

On 31 January 2020 the UK ceased to be a member of the EU and a limited trade deal was agreed between the UK and the EU with the relevant new regulations coming into force on 1 January 2021.

The trade deal, however, does not include agreements on certain areas such as financial services and data adequacy. As a result, Santander UK has, and will continue to have, a limited ability to provide cross-border services to EU customers and to trade with EU counterparties. The wider and continuing impact of Brexit on financial markets through market fragmentation, reduced access to finance and funding, and a lack of access to certain financial market infrastructure, may affect Santander UK's operations, financial condition and prospects and those of its customers.

Residual risks remain around the impact on the UK's economy. Brexit has contributed to global pandemic-related supply and labour market constraints and reduced economic output and exports as businesses attempt to adapt the new cross-border procedures and rules applicable in the UK and in the EU to their activities, products, customers and suppliers.

While the longer term effects of the UK's withdrawal from the EU are difficult to assess, this has also been hampered by overlay of and development of economic risks from the Covid-19 pandemic and the Russian invasion of Ukraine. Further, there is ongoing political and economic uncertainty, such as increased friction with the EU and EU countries, and the possibility of a second referendum on Scottish independence from the UK, which could negatively affect Santander UK's customers and counterparties and have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK faces risks from the impact of climate change, which could materially affect Santander UK's business operations, reputation, clients and customers, as well as the creditworthiness of its counterparties** 

Climate risk is a risk that manifests through other principal risks, primarily enterprise risk, credit risk and operational risk. Climate change could expose Santander UK to financial risk either through its physical (e.g., climate or weather-related events) or transitional (e.g., changes in climate policy or in the regulation of financial institutions and corporates with respect to climate change risks) effects. Transition risks could be further accelerated by the occurrence of changes in the physical climate.

Physical risks from climate change arise from climate and weather-related events, such as heatwaves, droughts, floods, landslides, storms, sea level rise, coastal erosion and subsidence. These risks could impact our customers in the form of lower revenues due to transport problems, supply chain disruption and other impacts that strain production and lower revenues and higher costs for our customers owing to workers' health, safety, absenteeism and other workforce-related problems. These risks could also lead to damage to our customers' property or operations, which could impair asset values and the creditworthiness of customers leading to increased default rates, delinquencies, write-offs and impairment charges in Santander UK's portfolios. In addition, Santander UK's premises and resilience may also suffer physical damage due to weather-related events leading to increased costs for Santander UK.

Transition risks arise from the process of adjustment towards a low-carbon economy. Santander UK may face significant and rapid developments in stakeholder expectations, policy, law and regulation which could impact the lending activities Santander UK undertakes, as well as the risks associated with its lending portfolios, and the value of Santander UK's financial assets. Reputation risk could arise from a failure to meet changing societal, investor or regulatory demands.

Banco Santander S.A. is a founding member of the UN-convened Net Zero Banking Alliance committing Santander UK Group Holdings plc to set and disclose decarbonisation targets for most greenhouse gas intensive sectors and to becoming a net zero bank by 2050. As such, Santander UK Group Holdings plc is implementing and reporting at a group level (including Santander UK plc) against the TCFD recommendations and has disclosed targets to manage climate-related risks and opportunities, however, we do not believe our climate-related disclosure is fully aligned with the TCFD recommendations yet. In order to fulfil these ambitions and reach the relevant targets or any other climate related ambitions or targets Santander UK may commit to in future, Santander UK will need to incorporate climate considerations into its strategy, business model, the products and services it provides to customers and its financial and non-financial risk management processes (including processes to measure and manage the various financial and non-financial risks Santander UK faces as a result of climate change). Failure to adequately embed risks associated with climate change into its risk framework to appropriately measure, manage and disclose the various financial and operational risks it faces as a result of climate change, or failure to adapt Santander UK's strategy and business model to the changing regulatory requirements and market expectations on a timely basis, may have a material and adverse impact on Santander UK's level of business growth, competitiveness, profitability, capital requirements, cost of funding, and financial condition. Achieving Santander UK's climate-related ambitions and targets will also depend on a number of factors outside its control, including (among other things) availability of data to measure and assess the climate impact on Santander UK's customers, advancements of low-carbon transition technologies and public policies to support the energy transition in the markets where Santander UK operates. If these external factors and other changes do not occur, or do not occur on a timely basis, Santander UK may fail to achieve its climate-related ambitions and targets and this could have a material adverse effect on Santander UK's business growth, competitiveness, profitability, financial condition and reputation. In 2023, we will continue to work on assessing our financed emissions and establishing interim targets. We will consider key enablers, including government policy as well as our own actions to accelerate the decarbonisation.

For further details on Santander UK's approach to climate change see "Sustainability & Responsible Banking – Taskforce on Climate-related Financial Disclosures (TCFD)" in the Santander UK Group Holdings plc Annual Report on Form 20-F.

**Business model risks**

**Santander UK is exposed to competition from other financial institutions, including new entrants into the financial services sector**

The markets for UK financial services are very competitive and Santander UK has seen strong competition from banks, building societies and other established financial service providers. In addition, Santander UK faces competition from a number of new entrants, non-banks and other providers, including technology companies and large retail companies with strong brand recognition.

The UK government and regulators are actively supporting the emergence of new entrants into the UK financial services market. The internet and mobile technologies are also changing customer behaviour and the competitive environment. There has been a steep rise in customer use of mobile banking in recent years and the Covid-19 pandemic accelerated the strong trends towards customer digital adoption. Santander UK is investing in a multi-year transformation programme, including digitalisation of channels and services and automation of physical channels, to both meet customer preferences and protect its competitive position. There can be no assurance that the transformation programme will deliver the benefits sought from it.

Management expects such competition to continue or intensify as a result of customer behaviour and trends, technological changes, competitor behaviour, the growth in digital banking, new lending models and changes in regulation (including the introduction of Open Banking and changes arising from the Payment Services Directive (PSD2)). As a result of any restructuring or evolution in the market, there may emerge one or more new viable competitors in the UK banking market or a material strengthening of one or more of Santander UK's existing competitors in that market, limiting Santander UK's ability to increase its customer base and expand its operations, increasing competition for investment opportunities and potentially reducing Santander UK's market share.

Any of these competition-related factors or a combination thereof could result in a significant reduction in the profit of Santander UK. Santander UK gives consideration to the competitive position in its management actions, such as pricing, product decisions and our business model. Increasing competition could mean that Santander UK increases rates offered on deposits or lowers the rates it charges on loans, or changes its cost base, any of which could have a material adverse effect on its operations, financial condition and prospects.

The rising rate environment and cost of living crisis may result in competitors reacting quite differently in relation to, amongst other factors, loan pricing, availability, deposit pricing, investment decisions. This has already had, and will continue to have, an impact on the competitive environment and future decisions of Santander UK.

**Santander UK's ability to maintain its competitive position depends, in part, on the success of new products and services it offers its customers and its ability to continue offering products and services from third parties**

The success of Santander UK's operations and its profitability depends, in part, on the success of new products and services it offers to customers and the way in which it offers and provides its products and services. The increasing availability of a wide range of digital or online products and services for customers requires banks like Santander UK to enhance their offerings in order to retain and attract customers. However, Santander UK cannot guarantee that its new products and services or the way in which it offers or provides its products and services will meet the needs or preferences of Santander UK's customers which may change over time, and such changes may render Santander UK's products and services obsolete, outdated or unattractive. Santander UK may not be able to develop new products that meet its customers' changing needs in a timely manner. As Santander UK expands the range of its products and services, some of which may be at an early stage of development in the UK market, it will be exposed to known, new and potentially increasingly complex risks, including conduct risk, and development

expenses. Santander UK's employees and risk management systems, as well as its experience and that of its partners, may not be sufficient or adequate to enable it to properly handle or manage such risks. In addition, the cost of developing products that are not launched is likely to affect its operating results.

Any or all of the above factors, individually or collectively, could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK's loan portfolio is subject to risk of prepayment**

Santander UK's loan portfolio is subject to prepayment risk resulting from the ability of a borrower or issuer to prepay a debt obligation prior to maturity. As a result Santander UK could be required to amortise net premiums into income over a shorter period of time, thereby reducing the corresponding asset yield and net interest income and there is a risk that Santander UK is not able to accurately forecast amortisation schedules for these purposes which may affect its profitability. Prepayment risk also has a significant adverse impact on credit card and mortgage loans, since prepayments could shorten the weighted average life of these assets, which may result in a mismatch with Santander UK's funding obligations and reinvestment at lower yields. The risk of prepayment and its impact on Santander UK's ability to accurately forecast amortisation schedules is inherent in Santander UK's commercial activity and an increase in prepayments or a failure to accurately forecast amortisation schedules could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Damage to Santander UK's reputation could cause harm to its business prospects**

Maintaining a positive reputation is critical to attracting and retaining customers, investors and employees and conducting business transactions with counterparties. Damage to the reputation of Santander UK or Banco Santander S.A. (as the ultimate parent of Santander UK), the reputation of affiliates operating under the 'Santander' brand or any of its other brands could therefore cause significant harm to Santander UK's business and prospects. Harm to Santander UK's reputation can arise directly or indirectly from numerous sources, including, among others, employee misconduct (including the possibility of employee fraud), litigation, regulatory interventions and enforcement action, failure to deliver minimum standards of service and quality, loss or compromise of customer data, disruption to service due to a cyber-attack, wider IT failures, compliance failures, third party fraud, financial crime, breach of legal or regulatory requirements, unethical behaviour (including adopting inappropriate sales and trading practices), and the activities of customers, suppliers and counterparties and the perception of the financial services industry as a whole. Further, negative publicity regarding Santander UK, whether true or not, may result in harm to Santander UK's operations, financial condition and prospects.

**If Santander UK is unable to manage the growth of its operations, this could have a material adverse impact on its profitability**

Santander UK allocates management and planning resources to develop strategic plans for organic growth, and to identify possible acquisitions and disposals and areas for restructuring its businesses when necessary. From time to time, Santander UK evaluates acquisition, disposal, and partnership opportunities that it believes could offer additional value to its shareholders and customers and are consistent with its business strategy. However, Santander UK may not be able to identify suitable acquisition or partnership candidates and may not be able to acquire promising targets or form partnerships on favourable terms, or at all. Furthermore, preparations for acquisitions that Santander UK does not complete can be disruptive. Santander UK bases its assessment of potential acquisitions and partnerships on limited and potentially inexact information and on assumptions with respect to value, operations, profitability and other matters that may prove to be incorrect. Santander UK's ability to benefit from any such acquisitions and partnerships will depend in part on its successful integration of those businesses. Such integration entails significant risks such as challenges in retaining the customers and employees of the acquired businesses, unforeseen difficulties in integrating operations and systems and unexpected liabilities or contingencies relating to the acquired businesses, including legal claims and regulatory investigations. Moreover, the success of the acquisition or venture will at least in part be subject to a number of political, economic and other factors that are beyond Santander UK's control. Santander UK can give no assurances that its expectations with regard to integration and synergies will materialise.

Santander UK cannot provide assurance that it will, in all cases, be able to manage its growth effectively or to implement its strategic growth decisions, including its ability to:

–Manage efficiently the operations and employees of expanding businesses

–Maintain or grow its existing customer base

–Successfully execute its strategy

–Fully due diligence and assess the value, strengths and weaknesses of investment or acquisition candidates

–Finance strategic opportunities, investments or acquisitions

–Fully integrate strategic investments, or newly-established entities or acquisitions, in line with its strategy

–Align its current information technology systems adequately with those of an enlarged group

–Apply its risk management policy effectively to an enlarged group

Any or all of these factors, individually or collectively, could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Capital and liquidity risk**

**Santander UK is subject to regulatory capital, liquidity and leverage requirements that could limit its operations, and changes to these requirements may further limit and could have a material adverse effect on Santander UK's operations, financial condition and prospects**

**Capital Requirements Regulation and Capital Requirements Directive IV**

Santander UK is subject to capital adequacy requirements applicable to banks and banking groups under retained EU law and as adopted by the Prudential Regulation Authority (PRA). Santander UK is required to maintain a minimum ratio of Common Equity Tier 1 (CET1) capital to risk-weighted assets, Tier 1 capital to risk-weighted assets, total capital to risk-weighted assets and Tier 1 capital (leverage) to total adjusted assets for leverage purposes. Any failure by Santander UK to maintain such ratios above prescribed regulatory minimum levels may result in administrative actions or sanctions. These could potentially include requirements on Santander UK to cease all or certain lines of new business, to raise new capital resources or, in certain circumstances, a requirement for Santander UK's existing capital instruments (potentially including Santander UK's debt securities) to be subjected to bail-in or write down (for more information, see the risk factor entitled 'Santander UK may become subject to the provisions of the Banking Act 2009 (the Banking Act), including bail-in and write down powers').

The EU Capital Requirements Directive IV (CRD IV Directive) and the Capital Requirements Regulation (the CRR and together with the CRD IV Directive, CRD IV) implemented changes proposed by the Basel Committee on Banking Supervision (the Basel Committee) to the capital adequacy framework, known as 'Basel III' in the EU. The CRR has been amended through a series of EU regulations, including the Capital Requirements Regulation 2 (CRR 2) and the CRD IV Directive amended by the Capital Requirements Directive V (CRD V Directive). The European Union (Withdrawal) Act 2018 converted the directly applicable elements of CRD IV into UK law on 31 December 2020 and preserved existing UK law implementing the CRD IV directive. Certain elements of the CRR which were 'onshored' in this way have now been transposed into the PRA rules.

In implementing CRD IV and the revised versions of CRD IV, the PRA has required the capital resources of UK banks to be maintained at levels which exceed the base capital requirements prescribed by CRD IV and to cover relevant risks in their business. In addition, a series of capital buffers have been established under CRD IV and PRA rules to ensure a bank can withstand a period of stress. Though the results of the PRA's 2019 stress test (the most recent exercise undertaken to set UK bank capital buffers) did not impact on the level of capital that Santander UK is required to hold, the PRA could, in the future, as a result of stress testing exercises

and as part of the exercise of UK macro-prudential capital regulation tools, or through supervisory actions, require Santander UK to increase its capital resources further, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Liquidity Coverage Ratio (LCR)**

The LCR is intended to ensure that a bank maintains an adequate level of unencumbered, high quality liquid assets which can be used to offset the net cash outflows the bank could encounter under a short-term significant liquidity stress scenario. The current minimum requirement for LCR is set at 100%. Santander UK is also required to maintain available stable funding equal to at least 100% of its required stable funding (the net stable funding ratio (NSFR)). Santander UK's current liquidity position is in excess of the minimum requirements set by the PRA, however there can be no assurance that future changes to the applicable liquidity requirements would not have an adverse effect on Santander UK's financial performance.

**Leverage ratios**

The Financial Services Act 2012 (the FS Act) also provides the Financial Policy Committee (FPC) of the BoE with certain macro-prudential tools for the management of systemic risk including quarterly setting of the countercyclical capital buffer rate and powers of direction relating to leverage ratios. All major UK banks and banking groups (including Santander UK) are required to hold enough Tier 1 capital (75% of which must be CET1 capital) to satisfy a minimum leverage ratio requirement of 3.25% and enough CET1 capital to satisfy a countercyclical leverage ratio buffer of 35% of each bank's institution-specific countercyclical capital buffer rate. The PRA requires UK globally systemically important banks (G-SIBs) and Ring Fenced Bodies to hold enough CET1 capital to meet an additional leverage ratio buffer of 35% of the institution-specific G-SIB buffer rate or Other Systemically Important Institutions (O-SII) buffer rate following the implementation of the CRD V Directive on 28 December 2020 (previously the Systemic Risk Buffer rate) and for consolidated groups which include a Ring Fenced Body (as defined in the Financial Services and Markets Act 2000 (FSMA) to hold enough CET1 capital to meet the Additional Leverage Ratio Buffer (ALRB). The FPC can also direct the PRA to adjust capital requirements in relation to particular sectors through the imposition of sectoral capital requirements. Action taken in the future by the FPC in exercise of any of its powers could result in the regulatory capital requirements applied to Santander UK being further increased, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Further regulatory changes**

Regulators in the UK and worldwide have proposed that additional loss absorbency requirements should be applied to systemically important institutions to ensure that there is sufficient loss absorbing and recapitalisation capacity available in resolution. The BoE is required to set the Minimum Requirement for Eligible Liabilities (MREL) for all institutions. The BoE required most banks, since 1 January 2022, to be in compliance with the end-state MREL requirements, which Santander UK plc and Santander UK Group Holdings plc are.

Regulators and legislators in the UK have produced a range of proposals for future legislative and regulatory reform which could force Santander UK to comply with certain operational restrictions or take steps to raise further capital or increase Santander UK's expenses and could therefore have a material adverse effect on Santander UK's operations, financial condition and prospects. These changes, which could affect Santander UK as a whole, include the UK's implementation of the remaining Basel III standards. The Basel Committee on Banking Supervision has approved a series of significant changes to the Basel regulatory capital and liquidity framework subsequent to Basel III from 7 December 2017, colloquially known as Basel IV or Basel 3.1, including additional capital requirements, higher capital ratios, more stringent eligibility requirements for capital instruments, a new leverage ratio and liquidity requirements. On 30 November 2022, the PRA published a consultation paper (CP) 16/22 on the implementation of the Basel IV standards (which the PRA refers to as Basel 3.1) in the UK (closing on 31 March 2023). This would revise the CRD IV framework already implemented in the UK and would have consequential impacts on the UK implementation of the leverage ratio, and elements of the liquidity and large exposures frameworks. The PRA has proposed a five-year transitional period for implementation that will become effective on 1 January 2025. CRD IV requirements adopted in the UK may change further, including as a result of policy developments associated with the migration of the CRD IV framework into domestic regulatory rules, as well as changes to the way in which the PRA continues to interpret and apply these requirements to UK banks (including as regards individual model approvals or otherwise).

There is a risk that changes to the UK's capital adequacy regime (including any increase to minimum leverage ratios) may result in increased minimum capital requirements, which could reduce available capital for new business purposes and adversely affect Santander UK's cost of funding, profitability and ability to pay dividends, or other discretionary payments on its capital instruments, continued organic growth (including increased lending), or pursue acquisitions or other strategic opportunities. Alternatively, Santander UK could be required to restructure its balance sheet to reduce capital charges incurred pursuant to the PRA's rules or raise additional capital, but at increased cost and subject to prevailing market conditions. In addition, any changes to the eligibility criteria for Tier 1 and Tier 2 capital may affect Santander UK's ability to raise Tier 1 and Tier 2 capital and impact the recognition of existing Tier 1 and Tier 2 capital resources in the calculation of Santander UK's capital position. Furthermore, increased capital requirements may negatively affect Santander UK's return on equity and other financial performance indicators.

Santander UK's business could be affected if its capital is not managed effectively or if these measures limit Santander UK's ability to manage its balance sheet and capital resources effectively or to access funding on commercially acceptable terms. Effective management of Santander UK's capital position is important to Santander UK's ability to operate its business, to continue to grow organically and to pursue its business strategy. There is a risk that implementing and maintaining existing and new liquidity requirements, such as through enhanced liquidity risk management systems, may incur significant costs, and more stringent requirements to hold liquid assets may materially affect Santander UK's lending business as more funds may be required to acquire or maintain a liquidity buffer, thereby reducing future profitability. This could in turn adversely impact Santander UK's operations, financial condition and prospects.

**Liquidity and funding risks are inherent in Santander UK's business and could have a material adverse effect on Santander UK's operations, financial condition and prospects**

Liquidity risk is the risk that Santander UK either does not have available sufficient financial resources to meet its obligations as they fall due or can secure them only at excessive cost. This risk is inherent in any retail and commercial banking business and can be heightened by a number of factors such as over-reliance on a particular source of funding, changes in credit ratings or market-wide phenomena such as market dislocation. Santander UK performs comprehensive internal stress testing in order to ensure that it maintains funding profiles and holds a liquid asset buffer in order to manage this risk. However, unforeseen systemic market factors like those experienced during the last financial crisis make it difficult to eliminate these risks completely. There can be no assurance that such circumstances will not reoccur or that they will occur in the same way, but past experience and comprehensive stress testing regimes help Santander UK to consider and manage the potential impacts on its liquidity position. Liquidity constraints may affect Santander UK's operations and its ability to meet regulatory liquidity requirements or may limit growth possibilities. Disruption and volatility in the global financial markets could have a material adverse effect on Santander UK's ability to access capital and liquidity on financial terms acceptable to it and in addition to increased funding costs, may result in a shortening in the term of funding it raises.

Santander UK's cost of funding is related to prevailing interest rates and to its credit spreads. Increases in interest rates and Santander UK's credit spreads can significantly increase the cost of its funding. Changes in Santander UK's credit spreads can be market-driven or idiosyncratic in nature and may be influenced by perceptions of its creditworthiness rather than any underlying change in Santander UK's financial position. Changes to interest rates and Santander UK's credit spreads occur continuously and may be unpredictable and highly volatile. Market predictions of future central bank policy rate paths may impact Santander UK's cost of funding, even if central bank actions do not ultimately follow market predictions.

If wholesale markets financing ceases to be available, or becomes excessively expensive, Santander UK may be forced to raise the rates it pays on deposits, with a view to attracting more customers and/or to sell assets, potentially at depressed prices or to reduce growth plans. Santander UK's cost of funding might also be impacted by increased competition for retail and corporate deposits.

In response to the Covid-19 pandemic, the BoE introduced the Term Funding Scheme with additional incentives for Small and Medium-Sized Enterprises (TFSME). Santander UK has begun repaying drawings ahead of the 2025 contractual maturities and as at 31 December 2022, Santander UK had £25bn of drawings outstanding having repaid £7bn in the fourth quarter of 2022. .

Each of the factors described above could have a material adverse effect on Santander UK, including its ability to access capital and liquidity on financial terms acceptable to it and, more generally, on its operations, financial condition and prospects.

Further, Santander UK aims for a funding structure that is consistent with its assets, avoids excessive reliance on short-term wholesale funding, attracts enduring retail and commercial deposits and provides diversification in products and tenor. Santander UK therefore relies, and will continue to rely, on retail and commercial deposits to fund a significant proportion of lending activities. The on-going availability of this type of funding is sensitive to a variety of factors outside Santander UK's control, such as general economic conditions and the confidence of depositors in the economy and in the financial services industry in general, confidence in Santander UK specifically, Santander UK's credit rating and the availability and extent of deposit guarantees, as well as competition between banks for deposits or competition with other products, such as mutual funds or, if launched, central bank digital currency. A change in any of these factors could significantly increase the amount of commercial deposit withdrawals in a short period of time, thereby reducing its ability to access deposit funding on appropriate terms, or at all, in the future, and therefore have a material adverse effect on Santander UK's operations, financial condition and prospects.

Santander UK's liquidity planning assumes that customers will continue to make a volume of deposits with Santander UK (particularly demand deposits and short-term time deposits), and Santander UK intends to maintain its emphasis on the use of deposits as a source of funds. The short-term nature of some deposits could cause liquidity problems for Santander UK in the future if deposits are not made in the volumes anticipated or are withdrawn at short notice or are not renewed. If a substantial number of depositors withdraw their demand deposits or do not roll over their time deposits upon maturity, there may be a material adverse effect on Santander UK's operations, financial condition and prospects. This might increase Santander UK's requirements for wholesale funding or require the execution of contingent options to raise additional liquidity, including the potential curtailing of growth plans.

**An adverse movement in Santander UK's external credit rating would likely increase its cost of funding, require Santander UK to post additional collateral or take other actions under some of its derivative contracts and adversely affect Santander UK's operations, financial condition and prospects**

Credit ratings affect the cost and other terms upon which Santander UK is able to obtain funding. Credit rating agencies regularly evaluate Santander UK, and their credit ratings of Santander UK and Santander UK's issued debt are based on a number of factors, including Santander UK's financial strength, the strength of the UK economy and conditions affecting the financial services industry generally.

Any downgrade in the external credit ratings assigned to Santander UK or any of Santander UK's debt securities could have an adverse impact on Santander UK. In particular, a downgrade in Santander UK's credit ratings could increase its borrowing costs and could require it to post additional collateral or take other actions under some of derivatives, loan facilities or other financial contracts, and could limit its access to capital markets and have a material adverse effect on its operations, financial condition and prospects. For example, a credit rating downgrade could have a material adverse effect on Santander UK's ability to sell or market certain products, engage in certain longer-term or derivatives transactions and retain its customers or investors, particularly those who need a minimum rating threshold in order to transact or invest.

Any of these effects of a credit rating downgrade could, in turn, result in outflows and reduce Santander UK's liquidity and have an adverse effect on Santander UK, including its operations, financial condition and prospects. For example, Santander UK estimates that at 31 December 2022, if Fitch, Moody's and Standard & Poor's were concurrently to downgrade the long-term credit ratings of Santander UK plc by one notch, and thereby trigger a short-term credit rating downgrade, this could result in an outflow of £1.4bn of cash and collateral. A hypothetical two notch downgrade would result in a further outflow of £0.7bn of cash and collateral at 31 December 2022. Under the LCR we hold sufficient liquidity to cover these potential outflows. However, while certain potential impacts are contractual and quantifiable, the full consequences of a credit rating downgrade are inherently uncertain, as they depend upon numerous dynamic, complex and inter-related factors and assumptions, including market conditions at the time of any downgrade, whether any downgrade of a firm's long-term credit rating precipitates downgrades to its short-term credit rating, whether any downgrade precipitates changes to the way that the financial institutions sector is rated, and assumptions about the ratings of other financial institutions and the potential behaviours of various customers, investors and counterparties. Actual outflows will also depend upon certain other factors including any management or restructuring actions that could be taken to reduce cash outflows and the potential liquidity impact from a loss of unsecured funding (such as from money market funds) or loss of secured funding capacity.

There can be no assurance that the credit rating agencies will maintain Santander UK's current credit ratings or outlooks. A failure to maintain favourable credit ratings or outlooks could increase Santander UK's cost of funding, adversely affect Santander UK's interest margins, and reduce its ability to secure both long-term and short-term funding. If a downgrade of a Santander UK member's long-term credit ratings were to occur, it could also impact the short-term credit ratings of other members of Santander UK. The occurrence of any of these events could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Negative changes to the UK sovereign credit rating, or the perception that further negative changes may occur, could have a material adverse effect on Santander UK's operations, financial condition, prospects and the marketability and trading value of its securities. This might also have an impact on Santander UK's own credit rating, borrowing costs and ability to secure funding. Negative changes to the UK sovereign credit rating, or the perception that further negative changes may occur, could also have a material effect in depressing consumer confidence, restricting the availability, and increasing the cost, of funding for individuals and companies, further depressing economic activity, increasing unemployment and reducing asset prices, which could in turn have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Changes in Santander UK's pension liabilities and obligations could have a materially adverse effect on Santander UK's operations, financial condition and prospects**

The majority of current employees are provided with pension benefits through defined contribution arrangements. Under these arrangements Santander UK's obligation is limited to the cash contributions paid. Santander UK provides retirement benefits for many of its former and current employees in the UK through a defined benefit pension scheme established under trust. Santander UK plc is the principal employer under this scheme, but it has only limited control over the rate at which it pays into the scheme. Under the UK statutory pension funding requirements employers are usually required to contribute to the schemes at the rate they agree with the scheme trustees although, if they cannot agree, the rate can be set by the Pensions Regulator. The scheme trustees may, in the course of discussions about future valuations, seek higher employer contributions. The scheme trustees' power in relation to the payment of pension contributions depends on the terms of the trust deed and rules governing the scheme, but, in some cases, the trustees may have the unilateral right to set the employer's relevant contribution.

The Pensions Regulator has the power to issue a financial support direction to companies within a group in respect of the liability of employers participating in UK defined benefit pension schemes where, amongst other things, that employer is 'insufficiently resourced' (as defined for the purposes of the relevant legislation).

---

Such a financial support direction could require the companies to guarantee or provide security for the pension liabilities of those employers or could require additional amounts to be paid into the relevant pension schemes in respect of them.

The Pensions Regulator can also issue contribution notices if it is of the opinion that an employer has taken actions, or failed to take actions, deliberately designed to avoid meeting its pension promises or which are materially detrimental to the scheme's ability to meet its pension promises. A contribution notice can be issued to any company or individual that is connected with or an associate of such employer in circumstances where the Pensions Regulator considers it reasonable to issue it and multiple notices could be issued to connected companies or individuals for the full amount of the debt. The risk of a contribution notice being imposed may inhibit Santander UK's freedom to restructure or to undertake certain corporate activities. There is a risk that Santander UK could incur an obligation to make a contribution to the scheme by virtue of section 75 or 75A of the Pensions Act 1995 as a result of a reorganisation or disposal of Santander UK's businesses.

Should the value of assets to liabilities in respect of the defined benefit schemes operated by Santander UK record a deficit or an increased deficit (as appropriate), due to either a reduction in the value of the pension fund assets (depending on the performance of financial markets) not matched by a fall in the pension fund liabilities and/or an increase in the scheme liabilities not matched by an increase in the pension fund assets due to changes in legislation, mortality assumptions, discount rate assumptions, inflation, or other factors, or there is a change in the actual or perceived strength of the employer's covenant, this could result in Santander UK having to make increased contributions to reduce or satisfy the deficits which would divert resources from use in other areas of its business and reduce its capital resources. Inflation in particular poses a significant risk to the pension fund as liabilities would be adversely impacted by an increase in long-term inflation. While Santander UK can control a number of the above factors, there are some over which Santander UK has no or limited control. Although the trustee of the schemes is obliged to consult with Santander UK before changing the pension schemes' investment strategy, the trustee has the final say and the ultimate responsibility for investment strategy rests with the trustee.

Changes in UK legislation and regulation through the Pension Schemes Act 2021 to address perceived failings in pension protection following recent high profile company insolvencies with large pension deficits may also affect Santander UK's position, Specific areas where concerns have been raised are levels of dividends where there is a pension scheme with a deficit and the length of time taken to address deficits. These changes in legislation or regulation could result in Santander UK having to make increased contributions to reduce or satisfy the deficits which would divert resources from use in other areas of its business and reduce its capital resources.

The scheme has material investments in illiquid assets consisting primarily of unlisted credit, private equity and property. The value of these investments can only be known when they are realised. The value in the accounts is an estimate of the fair value of these investments but the final realised value could be materially different and if less than the value used in the accounts could result in Santander UK having to make increased contributions to reduce or satisfy resulting deficits which would also divert resources from use in other areas of the business and reduce its capital resources.

Any increase in Santander UK's pension liabilities and obligations as a result of the foregoing factors could have a material adverse effect on Santander UK's operations, financial conditions and prospects.

**Market risks**

**Santander UK is subject to fluctuations in interest rates and other market risks, which could have a material adverse effect on Santander UK's operations, financial condition and prospects**

Market risk refers to the probability of variations in Santander UK's net interest income or in the market value of its assets and liabilities due to volatility of interest rates, credit spreads, exchange rates or equity prices.

Changes in interest rates would affect the following areas, among others, of Santander UK's business:

–Net interest income

–The value of Santander UK's derivatives transactions

–The value of Santander UK's securities holdings

–The value of Santander UK's loans and deposits

–The volume of loans originated

Interest rates are highly sensitive to many factors beyond Santander UK's control, including increased regulation of the financial sector, inflation, monetary policies, domestic and international economic and political conditions. Variations in interest rates could affect the interest earned on Santander UK's assets and the interest paid on its borrowings, thereby affecting its net interest income, which comprises the majority of its revenue, reducing its growth rate and profitability and potentially resulting in losses. In addition, costs Santander UK incurs putting into place strategies to reduce interest rate exposure could increase in the future, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Increases in interest rates may reduce the volume of loans originated by Santander UK. Sustained high interest rates have historically discouraged customers from borrowing and have resulted in increased delinquencies in outstanding loans and deterioration in the quality of assets. Increases in interest rates may also reduce the propensity of Santander UK's customers to prepay or refinance fixed-rate loans, reduce the value of its financial assets and reduce gains or require Santander UK to record losses on sales of Santander UK's loans or securities, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Negative changes in positions recorded at fair value could have a material adverse effect on Santander UK's operations, financial condition and prospects**

Santander UK has material exposures to securities, derivatives and other investments that are recorded at fair value and are therefore exposed to potential negative market changes. A widening of market credit spreads, reflecting the prevailing market conditions would negatively impact asset valuations in future periods and may result in negative changes in the fair values of Santander UK's financial assets. A tightening of Santander UK's own credit spreads would increase the magnitude of liabilities, thereby reducing net assets.

In addition, the value ultimately realised by Santander UK on disposal of assets and liabilities recorded at fair value may be lower than their current fair value; for example, during the last global financial crisis, financial markets were subject to periods of significant stress resulting in steep falls in perceived or actual financial asset values, particularly due to volatility in global financial markets and the resulting widening of credit spreads.

Santander UK is also exposed to changes in the market value of credit and funding spreads for the valuation of certain derivative contracts, the estimated value of which is negatively exposed to increases in the Credit Valuation Adjustment (CVA) spread and the Funding Fair Valuation Adjustment (FVA) spread over the lifetime of the transaction.

Any of these factors could require Santander UK to record negative changes in fair value which could have a material adverse effect on its operations, financial condition and prospects.

Santander UK is also exposed to changes in UK residential house price index levels, future index growth assumptions and house price index volatility. These impact the valuations of the portfolios of home reversion plans, lifetime mortgages and associated hedges held by Santander UK. In addition, the home reversion assets and mortgages are exposed to any changes in underlying mortality assumptions as maturity dates on these are not fixed and are driven by the vacation of the underlying property on a permanent basis by the plan holder. Specific property risk exists for each individual asset versus the indexed growth assumption at the point of maturity. Lifetime mortgages additionally have prepayment risk which is managed via a FVA based on historic data.

In addition, to the extent that fair values are determined using financial valuation models, such values may be inaccurate or subject to change, as the data used by such models may not be available or may become unavailable due to changes in market conditions, particularly for illiquid assets and in times of economic instability. In such circumstances, Santander UK's valuation methodologies require it to make assumptions, judgements and estimates in order to establish fair value.

Reliable assumptions are difficult to make and are inherently uncertain. Moreover, valuation models are complex, making them inherently imperfect predictors of actual results. Any consequential impairments or write-downs could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Santander UK invests in debt securities of the UK government largely for liquidity management purposes. At 31 December 2022, approximately 4% of Santander UK's total assets and 3% of Santander UK's securities portfolio were comprised of debt securities issued by the UK government. Any failure by the UK government to make timely payments under the terms of these securities, or a significant decrease in their market value, could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK is exposed to risks relating to the integrity and continued existence of reference rates**

As previously announced by the Financial Conduct Authority (FCA), all sterling, euro, Swiss franc and Japanese yen LIBOR settings, and the 1-week and 2-month USD LIBOR settings, ceased to be published based on panel bank submissions after 31 December 2021, and the remaining USD LIBOR settings (i.e., overnight, 1-month, 3-month, 6-month and 12-month) will either cease to be published or cease to be representative immediately after 30 June 2023. In September 2021, the FCA announced that it would compel the continued publication of the 1-, 3- and 6-month sterling (and Japanese yen) LIBOR settings after end-2021, using a 'synthetic' methodology for a limited time. The FCA announced subsequently that the 1- and 6-month sterling LIBOR 'synthetic' settings "will permanently cease immediately after final publication on 31 March 2023", and in November 2022, the FCA announced that the 3-month sterling LIBOR 'synthetic' setting would cease to be published after 31 March 2024.

During 2021, Santander UK – along with its customers and counterparties – agreed the transition to alternative reference rates for the majority of agreements referencing the LIBOR settings that ceased at the end of 2021. The number of un-transitioned agreements referencing 'synthetic' LIBOR settings has continued to reduce in 2022, with the transition of additional agreements being agreed during the year. Santander UK is also continuing to finalise the transition of agreements referencing continuing USD LIBOR settings.

The transition of LIBOR based agreements has been complex and involved a range of risks (including legal, conduct, system, model, accounting and reputational risks). Changes to, or the replacement of, benchmarks may cause contracts in which they are used to perform differently than in the past or may have other consequential effects. In particular, the transition of contracts from GBP LIBOR to an alternative reference rate (such as SONIA or the BoE base rate) has typically involved an adjustment to the terms of financial contracts to which Santander UK is a party. Whilst Santander UK, and its customers and counterparties, have agreed on the transition for most impacted agreements and Santander UK has taken steps to manage the risks outlined, there can be no assurance that these risks will not crystallise. This could have adverse effects on Santander UK's operations, financial condition, and prospects.

**Credit risks**

**If the level of non-performing loans increases or the credit quality of Santander UK's loans deteriorates in the future, or if Santander UK's loan loss reserves are insufficient to cover loan losses, this could have a material adverse effect on Santander UK's operations, financial condition and prospects**

Risks arising from changes in credit quality and the recoverability of loans and amounts due from counterparties are inherent in a wide range of Santander UK's businesses. Non-performing or low credit quality loans have in the past, and could continue to, have a material adverse effect on Santander UK's operations, financial condition and prospects.

In particular, the amount of Santander UK's reported non-performing loans may increase in the future as a result of growth in Santander UK's total loan portfolio, including as a result of loan portfolios that Santander UK may acquire in the future (the credit quality of which may turn out to be worse than Santander UK had anticipated), or factors beyond Santander UK's control, such as adverse changes in the credit quality of Santander UK's borrowers and counterparties, a general deterioration in the UK or global economic conditions (including without limitation, rising interest rates), the impact of political events, events affecting certain industries or events affecting financial markets and global economies. Broader inflationary pressures that impact a customer's ability to service debt payments could also lead to increased arrears in both unsecured and secured products.

There can be no assurance that Santander UK will be able to effectively control the level of impaired loans in, or the credit quality of, its total loan portfolio, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Interest rates payable on a significant portion of Santander UK's outstanding mortgage loan products fluctuate over time due to, among other factors, changes in the BoE base rate. As a result, borrowers with variable interest rate mortgage loans are exposed to increased monthly payments when the related mortgage interest rate adjusts upward. Similarly, borrowers of mortgage loans with fixed or introductory rates adjusting to variable rates after an initial period are exposed to the risk of increased monthly payments at the end of this period. Over the last few years both variable and fixed interest rates have been at historically low levels, which has benefited borrowers of new loans and those repaying existing variable rate loans regardless of special or introductory rates. Future increases in borrowers' required monthly payments may result in higher delinquency rates and losses related to non-performing loans going forward. Borrowers seeking to avoid these increased monthly payments by refinancing their mortgage loans may no longer be able to find available replacement loans at comparably low interest rates. These events, alone or in combination, may contribute to higher delinquency rates and losses for Santander UK, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Santander UK's current loan loss reserves may not be adequate to cover an increase in the amount of non-performing loans or any future deterioration in the overall credit quality of Santander UK's total loan portfolio. Santander UK's loan loss reserves are based on Santander UK's current assessment of various factors affecting the quality of its loan portfolio, including its borrowers' financial condition, repayment abilities, the realisable value of any collateral, the prospects for support from any guarantor, government macroeconomic policies, interest rates and the legal and regulatory environment. Many of these factors are beyond Santander UK's control. As a result, there is no precise method for predicting loan and credit losses, and no assurance can be provided that Santander UK's current or future loan loss reserves will be sufficient to cover actual losses.

If Santander UK's assessment of and expectations concerning the above-mentioned factors differ from actual developments Santander UK may need to increase its loan loss reserves, which may adversely affect Santander UK's operations, financial condition and prospects. Additionally, in calculating its loan loss reserves,

Santander UK employs qualitative tools and statistical models which may not be reliable in all circumstances and which are dependent upon data that may not be complete. If Santander UK is unable to control or reduce the level of its non-performing or poor credit quality loans, this could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**The value of the collateral, including real estate, securing Santander UK's loans may not be sufficient, and Santander UK may be unable to realise the full value of the collateral securing Santander UK's loan portfolio**

The value of the collateral securing Santander UK's loan portfolio may significantly fluctuate or decline due to factors beyond Santander UK's control, including macroeconomic factors affecting the UK's economy. Santander UK's residential mortgage loan portfolio is one of its principal assets, comprising 85% of Santander UK's loan portfolio at 31 December 2022. As a result, Santander UK is highly exposed to developments in the residential property market in the UK. House price growth was strong in the first half of 2022 with demand for housing also strong. However, in Q3 and Q4 prices started to fall and there remains a level of uncertainty in the outlook for house prices for 2023. The depth of the previous house price declines as well as the continuing uncertainty as to the extent and sustainability of the UK economic downturn and recovery will mean that losses could be incurred on loans should they go into possession.

The value of the collateral securing Santander UK's loan portfolio may also be adversely affected by force majeure events such as natural disasters like floods or landslides exacerbated by climate change trends. Any force majeure event may cause widespread damage and could have an adverse impact on the economy of the affected region and may therefore impair the asset quality of Santander UK's loan portfolio in that area.

Santander UK may also not have sufficiently up-to-date information on the value of collateral, which may result in an inaccurate assessment for impairment losses on loans secured by such collateral.

If any of the above events were to occur, Santander UK may need to make additional provisions to cover actual impairment losses of its loans, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Legal and regulatory risks**

**Santander UK is subject to substantial and evolving regulation and governmental oversight**

As a financial services group, Santander UK is subject to extensive financial services laws, regulations, administrative actions and policies in the UK, and in each other location in which Santander UK operates. For a discussion of the principal laws and regulations to which Santander UK is subject, see 'Regulation of the Santander UK group'. The sector continues to face unprecedented levels of government and regulatory intervention and scrutiny, and changes to the regulations governing financial institutions and the conduct of business. In addition, regulatory and governmental authorities have continued to consider further enhanced or new legal or regulatory requirements intended to reduce the probability and impact of future crises (or otherwise assure the stability and operational resilience of institutions under their supervision), enhance consumer protection, address climate change risks, the risk of greenwashing and environmental, social and governance risks generally, and improve controls in relation to financial crime-related risks. Santander UK expect regulatory and government intervention in the banking sector to remain high for the foreseeable future. An intensive approach to supervision is maintained in the UK by the PRA, the FCA, the Competition and Markets Authority (CMA), the Payment Systems Regulator (PSR), the Information Commissioner's Office (ICO) and the Lending Standards Board (LSB).

As well as being subject to UK regulation, as part of the Banco Santander group, Santander UK is also affected by other regulators such as the Banco de España (the Bank of Spain) and the European Central Bank (ECB), as well as various legal and regulatory regimes (including the US) that have extra-territorial effect. Extensive legislation and implementing regulations affecting the financial services industry have recently been adopted in regions that directly or indirectly affect Santander UK's business, including Spain, the US, the EU and other jurisdictions.

The manner in which financial services laws, regulations and policies are applied to the operations of financial institutions has gone through great change which is still being implemented and reviewed. Recent proposals and measures taken by governmental, tax and regulatory authorities and further future changes in supervision and regulation (in particular in the UK), are beyond Santander UK's control and could materially affect Santander UK's business.

Changes in UK legislation and regulation applicable to the financial sector may also affect Santander UK's competitive position, particularly if such changes are implemented before international consensus is reached on key issues affecting the industry.

To the extent these laws, regulations and policies apply to it, Santander UK may face higher compliance costs and the need to carefully manage capacity to readily respond to multiple regulatory or government policy changes simultaneously. Any legislative or regulatory actions and any required changes to Santander UK's business operations resulting from such laws, regulations and policies as well as any deficiencies in Santander UK's compliance with such laws, regulations and policies could result in significant loss of revenue, could have an impact on Santander UK's strategy, limit its ability to pursue business opportunities in which Santander UK might otherwise consider engaging, limit Santander UK's ability to provide certain products and services and/or result in enforcement action (including the imposition of financial and other penalties). They may also affect the value of assets that Santander UK holds, requiring Santander UK to increase its prices thereby reducing demand for Santander UK's products or otherwise have a material adverse effect on its operations, financial condition and prospects. Accordingly, there can be no assurance that future changes in laws, regulations and policies or in their interpretation or application by Santander UK or by regulatory authorities will not adversely affect Santander UK.

Specific examples of areas where regulatory changes and increased regulatory scrutiny could have a material adverse effect on Santander UK's operations, financial condition and prospects include, but are not limited to, the following:

–**Banking Reform:** In accordance with the provisions of the Financial Services (Banking Reform) Act 2013 UK banking groups that hold significant retail deposits, including Santander UK, were required to separate or 'ring-fence' their retail banking activities from their wholesale banking activities by 1 January 2019. Santander UK completed its ring-fencing plans in advance of the legislative deadline of 1 January 2019. However, given the complexity of the ring-fencing regulatory regime and the material impact on the way Santander UK conducts its business operations in the UK, there is a risk that Santander UK and/or Santander UK plc may be found to be in breach of one or more ring-fencing requirements. This might occur, for example, if prohibited business activities are found to be taking place within the ring-fence, mandated retail banking activities are found being carried on in a UK entity outside the ring-fenced part of the group or Santander UK breached a PRA ring-fencing rule. If Santander UK were found to be in breach of any of the ring-fencing requirements placed upon it under the ring-fencing regime, it could be subject to supervisory or enforcement action by the PRA, the consequences of which might include substantial financial penalties, imposition of a suspension or restriction on Santander UK's UK activities or, in the most serious of cases, forced restructuring of the UK group, entitling the PRA (subject to the consent of the UK government) to require the sale of a Santander ring-fenced bank or other parts of the UK group. Following HM Treasury's publication of the final report of the Independent Panel on Ring-Fencing and Proprietary Trading on 15 March 2022, HM Treasury announced its intention to consult on certain limited reforms to the ring-fencing regime during 2023, alongside broader proposals to raise the threshold above which ring-fencing requirements apply from £25bn to £35bn of retail deposits, and to align the ring-fencing regime with the UK resolution regime. These consultations may result in future changes to the regime or lead to further review or amendment of Santander UK's operational and compliance arrangements in relation to the regime.

**Competition:** Reviews and investigations by competition authorities (which in the UK include the CMA, the FCA and the PSR) into any aspect of Santander UK's operations or the functioning of any markets in which Santander UK operates.

**–Payments:** Santander UK has been required to make systems changes and update processes to comply with a number of new payment regulations at a European as well as domestic UK level. Within the UK, the Payment Systems Regulator has mandated Santander UK build systems and processes for both Confirmation of Payee as well as the Contingent Reimbursement Model Code (CRM) which both aim to reduce the level of customer fraud (particularly through our customers' manipulation into making payments known as 'Authorised Push Payment' fraud). Under these standards, Santander UK assumes responsibility for certain categories of customer losses and any inherent failing in system design may lead to fines from regulators and/or compensation being paid to customers. Santander UK also expects to see significant developments in the key UK payment systems architecture - with systems update of the high value Clearing House Automated Payment System (CHAPS) system through the Real Time Gross Settlement (RTGS) renewal as well as the 'New Payments Architecture' for faster payments, BACS and the other lower value retail payment schemes. Transitioning to the 'New Payments Architecture' will generate short-term challenges, including in successfully adopting the ISO20022 messaging standard while ensuring payment message completeness in alignment with regulatory requirements. PSD2 has been implemented and transposed into UK legislation in the Payment Services Regulations 2017 and the UK continues to build upon the requirements within the EBA Regulatory Technical Standards via the Open Banking API industry standard and build. Open Banking and PSD2 both have shown that they have the potential to exacerbate a number of existing risks including data loss/data protection, cyber security, fraud and wider financial crime risk, which in turn could give rise to increased costs, litigation risk and risk of regulatory investigation and enforcement activity.

**–Data Privacy:** Failure to comply with emerging and current laws and regulations concerning data privacy and localisation in a number of jurisdictions across the globe may result in regulatory sanctions. In particular, the General Data Protection Regulation (EU) 2016/679 (GDPR), including the GDPR as it forms part of UK domestic law by virtue of the EUWA (UK GDPR), and the Data Protection Act 2018 (DPA) imposes obligations on data controllers and rights for data subjects. The implementation of the UK GDPR and DPA has required substantial amendments to Santander UK's procedures and policies. The changes have had, and could continue to have, an adverse impact on Santander UK's business by increasing its operational and compliance costs. If there are breaches of UK GDPR obligations, Santander UK could face significant administrative and monetary sanctions as well as reputational damage. The occurrence of any of these events could have a material adverse effect on Santander UK's operations, financial condition and prospects. The Data Protection and Digital Information Bill was introduced on 18 July 2022 and is currently progressing through the various stages of the parliamentary process. Some proposed reforms, such as the requirement to implement a privacy management programme may result in a further increase in compliance and operational costs, if implemented. The proposed changes may also pose a risk to the EU Commission's adequacy finding in respect of the UK, as the UK's data protection laws may no longer be considered to be essentially equivalent to those of the EU, which would impact data flows from the EU to the UK.

–**Electronic Marketing:** For the purposes of the Privacy and Electronic Communications Regulations 2003 (PECR), Santander UK relies on legitimate interests and not consent as a lawful basis for its marketing activity (an opt-out model, rather than an opt-in model). This model limits Santander UK to marketing its own similar products and services only to its own customers who have not opted out of marketing. This model therefore prevents the marketing by Santander UK of Santander group companies' products and services by electronic means. This may put Santander UK at a competitive disadvantage. It is proposed to move from a legitimate interests to a consent model in the near future. There will be legal and regulatory risks associated with this transition, as well as systems updates costs to operationalise.

**–Consumer Duty:** In response to a requirement introduced into the FSMA, the FCA has published final rules and guidance on a broad consumer duty that firms undertaking regulated activities with retail clients should observe (the Consumer Duty). The Consumer Duty has three elements: A consumer Principle that provides a high-level expectation of conduct, a set of overarching Cross-cutting Rules which develop and amplify the standards of conduct that the FCA expects under the consumer Principle and a suite of rules and guidance setting more detailed expectations for a firm's conduct according to the four specific outcomes that represent the key elements of the firm and its consumer relationships (products and services, price and value, consumer understanding and consumer support). The Consumer Duty also includes requirements for firms to end unfair charges and fees, make it as easy to switch or cancel products as it was to take them out in the first place, provide helpful and accessible customer support, act quickly to respond to customer queries, provide timely, clear and easily understandable information to customers regarding products and services, provide products and services that are appropriate for their customers, and focus on the real and diverse needs of their customers, including those in vulnerable circumstances, at every stage and in each interaction. Firms will also need to monitor, evidence and report against many of the requirements. Final rules and guidance were published on 27 July 2022 and firms will have until 31 July 2023 to implement its requirements. For closed products or services, the FCA rules come into force on 31 July 2024. The Consumer Duty requires a review of, and changes to, Santander UK's products, services, policies, systems and procedures against the FCA requirements. The Consumer Duty will affect elements of Santander UK's business model and strategy, the products and services it offers and the pricing or costs of those products and services, which may in turn affect the revenue and profits that Santander UK is able to generate. It may result in an increase in civil litigation or claims to the Financial Ombudsman Service by customers alleging a breach of the Consumer Duty or in regulatory action by the FCA.

**–Insolvency:** Changes to the UK corporate insolvency regime were introduced through the Corporate Insolvency and Governance Act 2020, including a pre-insolvency moratorium process for corporates in financial difficulty to give a period of time to seek a rescue or restructure and a new restructuring plan insolvency procedure to enable debt restructures. The Finance Act 2020 re-established certain tax debts owed by corporates as secondary preferential debts, ranking ahead of debts owed to floating charge holders. The Debt Respite Scheme (Breathing Space Moratorium and Mental Health Crisis Moratorium) (England and Wales) Regulations 2020 (Breathing Space Regulations) (which came into force on 4 May 2021) give eligible individuals in England and Wales the ability to apply for a breathing space or mental health crisis moratorium during which creditors may not demand payment of interest or fees that accrue or enforce a debt owed by the applicant. The impact these changes will have in relation to the collection and recovery of loans to retail and corporate customers who are in financial difficulty or default continues to evolve.

**–Outsourcing and Third Party Risk Management:** In March 2021, the PRA published Supervisory Statement 2/21 on outsourcing and third party risk management (SS2/21). The PRA has stated that SS2/21 should be the primary source of reference for Santander UK when interpreting and complying with its requirements on outsourcing and third-party risk management. SS2/21 should be read alongside the EBA guidelines on outsourcing arrangements, and FCA rules and guidance on outsourcing which remain applicable and effective. A major development is that the scope of contracts which should meet the PRA requirements on outsourcing and third-party risk management has increased beyond that set out in the EBA guidelines on outsourcing. The PRA states that it expects material third-party agreements that are not outsourcing to be subject to controls that are as robust as the controls that would apply to outsourcing arrangements with an equivalent level of materiality. Also in March 2021, the PRA published Supervisory Statement 1/21 (SS1/21) which set out its expectations for the operational resilience of Santander UK's 'important business services'. These are services that a PRA regulated firm provides which, if disrupted, could pose a risk to that firm's safety and soundness or, the financial stability of the UK. Santander UK is required to identify and set impact tolerances for all its important business services which must, in all cases, include a time-based metric to measure the tolerable level of disruption to that important business service. Santander UK must ensure it is able to deliver its important business services within impact tolerances in severe but plausible scenarios. If Santander UK is unable to meet the PRA's requirements on outsourcing and third-party risk management then it may face supervisory measures, which could in turn have a material adverse effect on Santander UK's operations, financial condition and prospects.

**–Climate Change:** The UK government has announced its intention to roll out new sustainability disclosure requirements, which will expand on the those required under the TCFD framework, including transition plans to align to net-zero, as well as a new UK green taxonomy. Santander UK Group Holdings plc is implementing the recommendations of TCFD on a group level: further reporting will require additional gathering of data and operationalisation of reporting and there will be legal, reputational and regulatory risks should Santander UK Group Holdings plc fail to adequately report, or to demonstrate appropriate capabilities to transition and support its customers to transition to a low carbon economy.

**–Evolving Conduct and Regulatory Policy:** The CMA is seeking enhanced consumer protection powers and is considering policy issues that may impact financial services, for example 'loyalty penalties' and the impact of digitalisation on consumer outcomes. There is the potential that the CMA and FCA take different stances on certain policy issues in these spheres.

**–National Security and Investment Act:** The National Security and Investment Act 2021 came into force on 4 January 2022 in the UK, introducing a new national security screening regime with mandatory suspensory notifications required for corporate and financial transactions in certain sectors which meet the prescribed thresholds. The Act also grants the UK Government wide-ranging powers to intervene in transactions on national security grounds, even where the transaction is outside of the scope of the mandatory notification regime. The UK Government can impose heavy criminal and civil penalties under the Act for non-compliance. In the event that the UK Government intervenes in any of Santander UK's transactions and/or imposes any related penalties on Santander UK, this could result in reputational damage and could have a material adverse effect on Santander UK's operations, financial condition and prospects

**Santander UK may become subject to the provisions of the Banking Act, including bail-in and write down powers**

The special resolution regime set out in the Banking Act provides HM Treasury, the BoE, the PRA and the FCA with a variety of powers for dealing with UK deposit taking institutions (and, in certain circumstances, their holding companies) that are failing or likely to fail, including: (i) to take a bank or bank holding company into temporary public ownership; (ii) to transfer all or part of the business of a bank to a private sector purchaser; or (iii) to transfer all or part of the business of a bank to a 'bridge bank'. The special resolution regime also comprises a separate insolvency procedure and administration procedure each of which is of specific application to banks. These insolvency and administration measures may be invoked prior to the point at which an application for insolvency proceedings with respect to a relevant institution could be made.

If an instrument or order were made under the Banking Act in respect of an entity in Santander UK, such instrument or order (as the case may be) may, among other things: (i) result in a compulsory transfer of shares or other securities or property of such entity; (ii) have an impact on the rights of the holders of shares or other securities issued by Santander UK or such entity or result in the nullification or modification of the terms and conditions of such shares or securities; or (iii) result in the de-listing of the shares and/or other securities of such entity. In addition, such an order may affect matters in respect of Santander UK or such entity and/or other aspects of the shares or other securities of Santander UK or such entity, which may negatively affect the ability of Santander UK or such entity to meet its obligations in respect of such shares or securities.

Further, amendments to the Insolvency Act 1986 and secondary legislation have introduced changes to the treatment and ranking of certain debts with the result that certain eligible deposits will rank in priority to the claims of ordinary (i.e. non-preferred) unsecured creditors in the event of an insolvency. This may negatively affect the ability of unsecured creditors to recover sums due to them in an insolvency scenario.

If a 'bail-in' order were made under the Banking Act as amended by The Financial Services (Banking Reform) Act 2013 (see further 'Regulation of Santander UK - The Banking Act 2009'), such an order would be based on the principle that any creditors affected by the 'bail-in' order should receive no less favourable treatment than they would have received had the bank entered into insolvency immediately before the coming into effect of the bail-in power. The bail-in power includes the power to cancel or write down (in whole or in part) certain liabilities or to modify the terms of certain contracts for the purposes of reducing or deferring the liabilities of a bank under resolution and the power to convert certain liabilities into shares (or other instruments of ownership) of the bank. The bail-in power under the Banking Act may potentially be exercised in respect of any unsecured debt securities issued by a bank under resolution or an entity in Santander UK, regardless of when they were issued. Accordingly, the bail-in power under the Banking Act could be exercised in respect of Santander UK's debt securities. Public financial support would only be used as a last resort, if at all, after having assessed and utilised, to the maximum extent practicable, the resolution tools including the bail-in tool and the occurrence of circumstances in which bail-in powers would need to be exercised in respect of Santander UK or any entity in Santander UK would have a material adverse effect on Santander UK's operations, financial condition and prospects.

The PRA also has the power to make rules requiring a parent undertaking of a bank to make arrangements to facilitate the exercise of resolution powers, including a power to require a member of a banking group to issue debt instruments. The exercise of such powers could have an impact on the liquidity of Santander UK's debt instruments and could materially increase Santander UK's cost of funding.

In addition, the resolution authorities have the power to require institutions and groups to make structural changes to ensure legal and operational separation of 'critical functions' from other functions where necessary, or to require institutions to limit or cease existing or proposed activities in certain circumstances. As a result, Santander UK is required to identify such 'critical functions' as part of its resolution and recovery planning. If used in respect of Santander UK, these ex ante powers could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK must comply with anti-money laundering, anti-terrorism, anti-bribery and corruption, sanctions and anti-tax evasion laws and regulations and a failure to prevent or detect any illegal or improper activities fully or on a timely basis could have a material adverse effect on Santander UK's operations, financial condition or prospects**

Santander UK is required to comply with applicable anti-money laundering (AML), counter-terrorism financing (CTF), anti-bribery and corruption, sanctions, preventing the facilitation of tax evasion and other laws and regulations in the jurisdictions in which Santander UK operates. These laws and regulations require Santander UK, among other things, to conduct customer due diligence (including in respect of sanctions and politically-exposed person screening), ensure customer and transaction information is appropriately recorded, monitored and kept up to date and implement effective financial crime policies and procedures detailing what is required from those responsible in order to counter financial crime risks. The policies and procedures require the implementation and embedding of effective controls and monitoring within the businesses of Santander UK, which in turn requires ongoing changes to systems, technology and operational activities.

Santander UK is also required to conduct financial crime training for its staff and to report suspicious transactions and activity to appropriate law enforcement. Comprehensive and risk based financial crime training at a group-wide and business unit level is a key element of effective controls, with the FCA providing guidance on expectations within its Financial Crime Guide. Financial crime is continually evolving. This requires proactive and adaptable responses from Santander UK so that it is able to deter, detect and disrupt threats and criminality effectively. Even known threats can never be fully eliminated, and there will be instances where Santander UK may be used by other parties to engage in money laundering and other illegal or improper activities. Santander UK's staff, whom Santander UK rely heavily upon to identify such activities and report them, have varying degrees of experience in recognising criminal tactics, making effective, bank-wide mandatory and specialist training provided by the Santander UK Anti-Financial Crime Academy more pertinent.

Where Santander UK outsources any of its customer due diligence, customer screening or anti-financial crime operations, it remains responsible and accountable for full compliance and any breaches. If Santander UK is unable to apply the necessary scrutiny and oversight, or if such oversight proves insufficient to detect illegal or improper activities, there remains a risk of regulatory breach and this could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Over the last decade, AML, CTF, anti-bribery and corruption and sanctions laws and regulations have become, and may continue to become, increasingly complex and detailed. Consequently, financial crime risk has become the subject of enhanced regulatory scrutiny and supervision by regulators globally, and such scrutiny continues to intensify. To manage regulatory scrutiny, Santander UK requires improved systems, sophisticated monitoring and skilled compliance personnel. Navigating the increasing complexity of financial crime regulation is a significant challenge, involving overlapping requirements between different legislation, and, in some instances, conflicts of laws. The divergence of policy approaches between the EU, UK and US in the area of economic sanctions and the evolving financial and trade sanctions imposed on Russia and Belarus due to the war in Ukraine, require additional immediate and longer-term sanctions risk management and compliance efforts for Santander UK.

UK AML and CTF legislation continues to change (for instance through regular updates to the UK's list of third countries identified as high-risk countries), recent updates to beneficial ownership discrepancy reporting requirements detailed in the UK's Money Laundering Regulations, or the recent launch of the Register of Overseas Entities and the associated compliance regime, which can lead to substantial amendments to Santander UK's AML and CTF procedures and policies, with additional training and guidance required for employees. While legislative changes can offer opportunities to increase effectiveness and efficiency in the overall anti-financial crime system, there are also risks of legislative and regulatory divergence from EU requirements. Significant change could adversely impact

Santander UK's business by increasing its operational and compliance costs and reducing the value of its assets and operations, which would in turn have a material adverse effect on Santander UK's operations, financial condition and prospects.

If Santander UK is unable to fully comply with applicable laws, regulations and expectations, its regulators and relevant law enforcement agencies have the ability and authority to pursue civil and criminal proceedings against it, to impose significant fines and other penalties on it, including requiring a complete review of Santander UK's business systems, day-to-day supervision by external consultants, imposing restrictions on the conduct of Santander UK's business and operations and ultimately the revocation of Santander UK's banking licence. The reputational damage to its business and brand could be severe if Santander UK was found to have materially breached AML, CTF, anti-bribery and corruption, anti-tax evasion or sanctions requirements. Santander UK's reputation could also suffer if it were unable to protect its customers or its business from being used by criminals for illegal or improper purposes. Criminal penalties could be imposed upon individuals employed by Santander UK. Any of these outcomes could have a material adverse effect on Santander UK's operations, financial condition and prospects.

At an operational level, geo-political, economic and social changes can provide opportunities to financial criminals and alter the risks posed to banks. Effective intelligence and monitoring systems within strengthened public/private partnerships supported by improved national capabilities to share knowledge on emerging risks and information pre-suspicion are required to help manage these risks. However, there can be no guarantee that any intelligence shared by public authorities or other financial institutions will be accurate or effective in helping Santander UK to combat financial crime, and if, despite such efforts, Santander UK fails to combat financial crime effectively then this could have a material adverse effect on Santander UK's operations, financial condition and prospects.

In addition, while Santander UK reviews its relevant counterparties' internal policies and procedures (for example, under its correspondent banking relationships) with respect to such matters, Santander UK, to a large degree, depends upon its relevant counterparties to maintain and properly apply their own appropriate anti-financial crime procedures. Such measures, procedures and compliance may not be completely effective in preventing third parties from using its (and its relevant counterparties') services as a conduit for money laundering (including illegal cash operations) without its (or its relevant counterparties') knowledge. There are also risks that other third parties, such as suppliers, could be involved in financial crime. If Santander UK is associated with, or even accused of being associated with, financial crime (or a business involved in financial crime), then its reputation could suffer and it could become subject to civil or criminal proceedings that could result in penalties, sanctions and legal enforcement (including being added to 'black lists' that would prohibit certain parties from engaging in transactions with it), any one of which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK is subject to tax-related risks**

Santander UK is subject to the substance and interpretation of UK tax laws and is subject to routine review and audit by tax authorities in relation thereto. Santander UK's interpretation or application of these tax laws may differ from those of the relevant tax authorities. While Santander UK provides for potential tax liabilities that may arise on the basis of the amounts expected to be paid to the tax authorities, the amounts ultimately paid may differ materially from the amounts provided depending on the ultimate resolution of such matters. In general, changes to tax laws and tax rates, including as a result of policy changes by governments and/or regulators, and penalties for failing to comply with such changes, could have a material adverse effect on Santander UK's operations, financial condition and prospects. Some of these changes may be specific to the banking/financial services sectors and therefore result in Santander UK incurring an additional tax burden when compared to other industry sectors.

**Santander UK is exposed to risk of loss and damage from civil litigation and/or criminal legal and regulatory proceedings**

Santander UK faces various legal and regulatory issues that have given rise and may give rise to civil or criminal litigation, arbitration, and/or criminal, tax, administrative and/or regulatory investigations, inquiries or proceedings. Failure to adequately manage the risks arising in connection with legal and regulatory issues, including Santander UK's obligations under existing applicable laws and regulations or its contractual obligations, including arrangements with its customers and suppliers, or failure to properly implement applicable laws and regulations could result in significant loss or damage including reputational damage, all of which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Additionally, the current regulatory environment, with the continuing heightened supervisory focus, combined with the forthcoming regulatory change initiatives, will lead to material operational and compliance costs. Relevant risks include:

–Regulators, agencies and authorities with jurisdiction over Santander UK, including the BoE, the PRA and the FCA, HM Treasury, HM Revenue & Customs (HMRC), the CMA, the Information Commissioner's Office, the Financial Ombudsman Service (FOS), the PSR, the Serious Fraud Office (SFO), the National Crime Agency (NCA), the Office of Financial Sanctions (OFSI) or the courts, may determine that certain aspects of Santander UK's business have not been or are not being conducted in compliance with applicable laws or regulations (or that policies and procedures are inadequate to ensure compliance), or, in the case of the FOS, with what is fair and reasonable in the FOS's opinion. Changes in policy, laws and regulations including in relation to small and medium sized enterprise (SME) dispute resolution and liability for authorised push payment fraud and unauthorised payment fraud, may have significant consequences and lead to material implementation, operational and compliance costs.

–An adverse finding by a regulator, agency or authority could result in the need for extensive changes in systems and controls, business policies, and practices coupled with suspension of sales, restrictions on conduct of business and operations, withdrawal of services, customer redress, fines and reputational damage.

–The increased focus on competition law in financial services and concurrent competition enforcement powers for the FCA and PSR may increase the likelihood of competition law related inquiries or investigations initiated by either the CMA or these authorities. In addition, the CMA's widening focus on market outcomes may result in increased reviews by the CMA of the markets in which Santander UK operates. Santander UK may be liable for damages to third parties harmed by Santander UK's conduct of business. For competition law, there are efforts by governments across Europe to promote private enforcement as a means of obtaining redress for harm suffered as a result of competition law breaches. Under the Consumer Rights Act 2015, there is scope for class actions to be used to allow the claims of a whole class of claimants to be heard in a single action in both follow-on and standalone competition cases.

–The alleged historical or current misselling of, or misconduct in relation to, financial products, including the alleged misselling of Payment Protection Insurance (PPI), the alleged overcharging of interest, the alleged inappropriate sale of interest-only mortgages, the alleged unfair use of the standard variable rate in connection with mortgages, the alleged non-disclosure of commission, including auto finance related commission giving rise to an alleged unfair relationship, or alleged misconduct as a result of having sales practices and/or rewards structures that are deemed to have been inappropriate, has given rise to and may in the future give rise to a risk of complaints to FOS and/or civil litigation (including claims management company driven legal or complaints campaigns)(see Note 31 to the Consolidated Financial Statements for legal actions and regulatory matters). Such matters may in the future give rise to the risk of regulatory enforcement action requiring Santander UK to amend sales processes, withdraw products or provide restitution to affected customers, any of which may require additional provisions to be recorded in Santander UK's financial statements and could adversely impact future revenues from affected products.

–Santander UK may have held and may continue to hold bank accounts for entities or have relationships with entities such as third parties that might be or are subject to scrutiny from various regulators and authorities, including the SFO, the NCA and regulators in the US and elsewhere, which has led and could in the future lead to Santander UK's conduct being reviewed as part of any such scrutiny.

–Santander UK is (and will continue from time to time to be) subject to certain legal or regulatory investigations, inquiries and proceedings, both civil and criminal including in connection with Santander UK's lending and payment activities, treatment of customers, relationships with Santander UK's employees, financial crime, and other commercial or tax matters (see Note 31 to the Consolidated Financial Statements for legal actions and regulatory matters). These may be brought against Santander UK under UK legal or regulatory processes, or under legal or regulatory processes in other jurisdictions, such as the EU and the US, in circumstances where overseas regulators and authorities may have jurisdiction by virtue of its activities or operations.

–In view of the inherent difficulty of predicting the outcome of legal or regulatory proceedings, particularly where opportunistic claimants seek very large or indeterminate damages, cases present novel legal theories, involve a large number of parties or are in the early stages of discovery, or where the approaches of regulators or authorities to legal or regulatory issues and sanctions applied are subject to change, Santander UK cannot state with confidence what the eventual outcome of any pending matters will be and any such pending matters are not disclosed by name because they are under assessment. Santander UK's provisions in respect of any pending legal or regulatory proceedings are made in accordance with relevant accounting requirements. These provisions are reviewed periodically. However, in light of the uncertainties involved in such legal or regulatory proceedings, there can be no assurance that the ultimate resolution of these matters will not exceed the provisions currently accrued by Santander UK. As a result, the outcome of a particular matter (whether currently provided or otherwise) could have a material adverse effect on Santander UK's operations, financial condition and prospects.

–The developing legal and regulatory regime in which Santander UK operates requires it to be compliant across all aspects of its business, including the training, authorisation and supervision of personnel and the development of systems, processes and documentation. If Santander UK fails to be compliant with relevant law or regulation, there is a risk of an adverse impact on its business from more proactive regulatory intervention (including by any overseas regulator which establishes jurisdiction), investigation and enforcement activity leading to sanctions, fines, civil or criminal penalties, or other action imposed by or agreed with the regulatory authorities, as well as increased costs associated with responding to regulatory inquiries and defending regulatory actions. Customers of financial services institutions, including Santander UK's customers, may seek redress if they consider that they have suffered loss for example as a result of the misselling of a particular product, or through incorrect application or enforcement of the terms and conditions of a particular product or in connection with a competition law infringement and Santander UK's rights under a contract with its customers may in certain circumstances be unenforceable or otherwise impaired.

–The Financial Services and Markets Act 2000 (Designated Consumer Bodies) Order 2013 (the Designated Consumer Bodies Order) was made on 16 December 2013 and came into force on 1 January 2014. The Designated Consumer Bodies Order designates the National Association of Citizens Advice Bureaux, the Consumers' Association, the General Consumer Council for Northern Ireland and the National Federation of Self Employed and Small Businesses as consumer bodies that may submit a 'super-complaint' to the FCA. A 'super-complaint' is a complaint made by any of these designated consumer bodies to the FCA on behalf of consumers of financial services where it considers that a feature, or a combination of features, of the market for financial services in the UK is seriously damaging the interests of these customers. Complaints about damage to the interests of individual consumers will continue to be dealt with by the FOS. If a 'super-complaint' were to be made against a Santander UK entity by a designated consumer body under the Designated Consumer Bodies Order, any response published or action taken by the FCA could have a material adverse effect on Santander UK's operations, financial condition and prospects.

Given the: (i) requirement for compliance with an increasing volume of relevant laws and regulations; (ii) more proactive regulatory intervention and enforcement and more punitive sanctions and penalties for infringement; (iii) inherent unpredictability of litigation; (iv) evolution of the jurisdiction of FOS and CMA and related impacts; (v) development of a voluntary dispute resolution service to oversee the resolution of historic complaints from SMEs that meet the relevant eligibility criteria and new complaints from SMEs that would be outside the FOS' proposed revised jurisdiction; (vi) introduction of a voluntary code to enhance protection for customers who are victims of authorised push payment fraud; and (vii) high volume of new regulations or policy changes from multiple regulators and authorities which Santander UK is mandated to implement within compressed timescales; it is possible that related costs or liabilities could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Operational risks**

**Failure to successfully apply or to improve Santander UK's credit risk management systems could have a material adverse effect on Santander UK's operations, financial condition and prospects**

As a commercial banking group, one of the main types of risks inherent in Santander UK's business is credit risk. For example, an important feature of Santander UK's credit risk management system is to employ Santander UK's own credit rating system to assess the particular risk profile of a customer. This system is primarily generated internally, but, in the case of counterparties with a global presence, also builds off the credit assessment assigned by other Banco Santander Group members. As this process involves detailed analysis of the customer or credit risk, taking into account both quantitative and qualitative factors, it is subject to human and IT systems errors. Where exercising their judgement on current or future credit risk behaviour of Santander UK's customers, Santander UK's employees may not always be able to assign a correct credit rating, which may result in a larger exposure to higher credit risks than indicated by Santander UK's risk rating system. Santander UK may not be able to detect all possible risks before they occur, or its employees may not be able to effectively apply its credit policies and guidelines due to limited tools available to Santander UK, which may increase its credit risk.

Any failure to effectively apply, consistently monitor and refine Santander UK's credit risk management systems may result in an increase in the level of non-performing loans and higher losses than expected, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK's data management policies and processes may not be sufficiently robust**

Critical business processes across Santander UK rely on large volumes of data from a number of different systems and sources. If data governance (including data retention and deletion, data quality and data architecture policies and procedures) is not sufficiently robust, manual intervention, adjustments and reconciliations may be required to reduce the risk of error in Santander UK 's external reports or in reporting to senior management or regulators. Inadequate policies and processes may also affect Santander UK's ability to use data to service customers more effectively or to improve Santander UK's product offering. Santander UK must also comply with requirements under law or regulation which require classification of customers, counterparties, financial transactions or instruments. Santander UK must also comply with the requirements under law or regulation in respect of the use of and protection of customer data and must mitigate the risk of any misuse or loss of data owing to failure of a data management process or an employee breach. Financial institutions that fail to comply with in-country (local) and global regulatory and compliance requirements may face supervisory measures, which could in turn have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK's business is subject to risks related to cyber-crime**

Santander UK's systems, software and networks may be vulnerable to unauthorised access, misuse, computer viruses or other malicious code and other events that could have a security impact. The interception, misuse or mishandling of personal, confidential or proprietary information sent to or received from a client, vendor, service provider, counterparty or third party could result in legal liability, regulatory action and reputational harm, and therefore have a material adverse effect on Santander UK's operations, financial condition and prospects.

In particular, in recent years the computer systems of companies and organisations have been targeted by cyber criminals, activists and nation-state-sponsored groups. Like other financial institutions, Santander UK manages and holds confidential personal information of customers in the conduct of its banking operations, as well as a large number of assets. Consequently, Santander UK has been, and continues to be, subject to a range of cyber-attacks, such as malware, phishing and denial of service.

Cyber-attacks could result in the loss of significant amounts of customer data and other sensitive information, as well as significant levels of liquid assets (including cash). In addition, cyber-attacks could give rise to the disablement of Santander UK's electronic systems used to service its customers. Any material disruption or degradation of Santander UK's systems could cause information, including data related to customer requests, to be lost or to be delivered to Santander UK's clients with delays or errors, which could reduce demand for Santander UK's services and products. As attempted attacks continue to evolve in both scope and sophistication, Santander UK may incur significant costs in order to modify or enhance its protective measures against such attacks, or to investigate or remediate any vulnerability or resulting breach, or in communicating cyber-attacks to its customers. If Santander UK fails to effectively manage its cyber security

risk, the impact could be significant and may include harm to Santander UK reputation and make Santander UK liable for the payment of customer compensation, regulatory penalties and fines. Factors such as failing to apply critical security patches from its technology providers, to manage out obsolete technology or to update Santander UK's processes in response to new threats could give rise to these consequences, which, if they occur, could have a material adverse effect on Santander UK's operations, financial condition and prospects. This might also include significant increases in the premiums paid on cyber insurance policies or changes to policy limits and cover.

In addition, Santander UK may also be affected by cyber-attacks against national critical infrastructures in the UK or elsewhere, for example, the telecommunications network or cloud computing providers used by Santander UK. In common with other financial institutions Santander UK is dependent on such networks to provide digital banking services to its customers, connect its systems to suppliers and counterparties, and allow its staff to work effectively from their homes. Any cyber-attack against these networks could negatively affect its ability to service its customers. As Santander UK does not operate these networks it has limited ability to protect Santander UK's business from the adverse effects of cyber-attack against them. Further, the domestic and global financial services industry, including key financial market infrastructure, may be the target of cyber disruption and attack by cyber criminals, activists or governments looking to cause economic instability. Santander UK has limited ability to protect its business from the adverse effects of cyber disruption or attack against its counterparties and key national and financial market infrastructure. If such a disruption or attack were to occur it could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK is exposed to risk from potential non-compliance with policies, employee misconduct, human error, negligence and deliberate acts of harm or dishonesty, including fraud**

Santander UK is exposed to risk from potential non-compliance with policies, employee misconduct, human error, negligence and deliberate acts of harm or dishonesty, including fraud. It is not always possible to deter or prevent such errors, acts, omissions and failures and the precautions Santander UK takes to detect and prevent this activity may not always be effective. Any instances could result in regulatory sanctions and cause reputational or financial harm, and therefore have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Any failure to effectively manage changes in Santander UK's information technology infrastructure and management information systems in a timely manner could have a material adverse effect on Santander UK's operations, financial condition and prospects**

Santander UK's businesses and its ability to remain competitive depends to a significant extent upon the functionality of its information technology systems and on its ability to upgrade and expand the capacity of its information technology infrastructure on a timely and cost-effective basis. The proper functioning of Santander UK's financial control, risk management, credit analysis and reporting, accounting, customer service, financial crime, conduct and compliance and other information technology systems, as well as the communication networks between branches and main data processing centres, are critical to its customers, businesses and its ability to compete. Investments and improvements in Santander UK's information technology infrastructure are regularly reviewed with a view to retain competitive advantage and to ensure that resilience remains within acceptable levels. Conversely any failure to effectively improve, expand or upgrade its information technology infrastructure and management information systems in a timely manner could have a material adverse effect on Santander UK's operations, financial condition and prospects, and could cause reputational damage to Santander UK.

From time-to-time Santander UK is required to migrate information relating to its customers to new information technology systems. Any failure to manage such migration effectively could have a negative impact on Santander UK's ability to provide services to its customers and could cause reputational damage to Santander UK.

Santander UK expects its programmes of change to have an effect on its risk profile, both technological and regulatory. Whether it is the opportunities from adoption of cloud technology, systems to support important regulatory initiatives, or the desire to identify, prioritise and remove obsolete systems from operations, the operational risk associated with programmes of systems change is likely to increase and this will therefore remain an area of key focus in Santander UK's risk management. While internal controls aim to reduce the risk to acceptable levels, there can be no assurance that Santander UK will not suffer material losses from such operational risks in the future, which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK may be exposed to unidentified or unanticipated risks despite its risk management policies, procedures and methods and may be exposed to risk related to errors in Santander UK's risk modelling**

The management of risk is an integral part of Santander UK's activities. Santander UK seek to monitor and manage its risk exposure through a variety of risk reporting systems. For a further description of our risk management framework see the 'Risk review'. While Santander UK employs a broad and diversified set of risk monitoring and risk mitigation techniques and strategies, they may not be fully effective in mitigating Santander UK's risk exposure in all economic market environments or against all types of risk, including risks that Santander UK fails to identify or anticipate.

Some of Santander UK's tools and metrics for managing risk are based upon its use of observed historical market behaviour. Santander UK applies statistical and other tools to these observations to arrive at quantifications of its risk exposures. These tools and metrics may fail to predict future risk exposures. These risk exposures could, for example, arise from factors Santander UK did not anticipate or correctly evaluate in its statistical models. This would limit its ability to manage its risks. Santander UK's losses thus could be significantly greater than the historical measures indicate. In addition, Santander UK's quantified modelling does not take all risks into account. Santander UK's more qualitative approach to managing those risks could prove insufficient, exposing it to material, unanticipated losses. Santander UK could face adverse consequences as a result of decisions, which may lead to actions by management, based on models that include errors or are otherwise inadequately developed, implemented or used, or as a result of the modelled outcome being misunderstood. If existing or potential customers or counterparties believe its risk management is inadequate, they could take their business elsewhere or seek to limit their transactions with Santander UK. These occurrences could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK relies on third parties and affiliates for important infrastructure support, products and services**

Third party providers and certain affiliates provide key components of Santander UK's business infrastructure such as loan and deposit servicing systems, back office and business process support, information technology production and support, internet connections and network access. Relying on these third party providers and affiliates is a source of operational and regulatory risk, including with respect to security breaches affecting our third parties and other parties that interact with these providers. As the use and depth of Santander UK's relationship with these third parties and affiliates increases, including the use of cloud based services, Santander UK increasingly faces the risk of operational failure with respect to its systems. Santander UK may be required to take steps to protect the integrity of its operational systems, thereby increasing its operational costs. In addition, any problems caused by these third parties or affiliates, including as a result of them not providing Santander UK their services for any reason, or performing their services poorly, could adversely affect Santander UK's ability to deliver products and services to customers and otherwise conduct its business, which could lead to reputational damage, litigation and regulatory investigations and intervention. Replacing these third party vendors or affiliates could also entail significant delays and expense. Further, the operational and regulatory risk Santander UK faces as a result of these arrangements may be increased to the extent that it restructures such arrangements. Any restructuring could involve significant expense to Santander UK and entail significant delivery and execution risk which could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Santander UK relies on recruiting, retaining and developing appropriate senior management and skilled personnel**

Santander UK's continued success depends in part on the continued service of key members of its senior executive team and other key employees. The ability to continue to attract, develop, train, motivate and retain highly qualified and talented professionals is a key element of Santander UK's strategy. The successful implementation of Santander UK's strategy depends on the availability of skilled and appropriate management, both at Santander UK's head office and in each of its business units. There is also an increasing demand for Santander UK to hire individuals with digital skills such as data scientist, engineering and designer skill sets. Such individuals are very sought after by all organisations, not just the banking industry, and thus Santander UK's ability to attract and hire this talent will determine how quickly the bank is able to respond to technological change. In light of a shortage of skills currently being seen across the UK, it is increasingly challenging to recruit and retain talent for all roles, with subject matter expert and customer facing roles offering the biggest challenges.

If Santander UK fails to staff its operations appropriately or loses one or more of its key senior executives or other key employees and fails to replace them in a satisfactory and timely manner, it could have a material adverse effect on Santander UK's operations, financial condition and prospects.

In addition, the financial services industry has and may continue to experience more stringent regulation of employee compensation, which could have an adverse effect on Santander UK's ability to hire or retain the most qualified employees. If Santander UK fails or is unable to attract and appropriately develop, motivate and retain qualified professionals, it could have a material adverse effect on Santander UK's operations, financial condition and prospects.

**Financial reporting risk**

**Santander UK's financial statements are based in part on judgements and accounting estimates which, if inaccurate, could cause material misstatement of Santander UK's future financial results and financial condition.**

The preparation of Santander UK's consolidated financial statements in accordance with IFRS requires management to make judgements, estimates and assumptions in applying the accounting policies that affect the reported amounts of assets, liabilities, income and expenses. Due to the inherent uncertainty in making estimates, actual results reported in future periods may be based on amounts which differ from those estimates. Estimates, judgements and assumptions are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. There has been no change in the inherent sensitivity of the areas of judgement in the period. Management has considered the impact of developments in principal risks and uncertainties, as set out in the Risk review, on critical judgements and accounting estimates.

The significant judgements, apart from those involving estimation, made by management in applying Santander UK's accounting policies in these financial statements (key judgements) and the key sources of estimation uncertainty that may have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities within the next financial year (key estimates), which together are considered critical to Santander UK's results and financial position, are set out in Note 1 to the Consolidated Financial Statements in 'Critical judgements and accounting estimates'. Any material differences between estimates and actual results reported in any given financial period, or any material adjustments to the carrying amount of assets and liabilities, could result in reputational damage to Santander UK and could have a material adverse effect on its future financial results and financial condition.

**Changes in accounting standards could affect reported earnings**

The accounting standard setters and other regulatory bodies periodically change the financial accounting and reporting standards that govern the preparation of Santander UK's Consolidated Financial Statements. These changes can materially affect how Santander UK records and reports its financial condition and financial results. In some cases, Santander UK could be required to apply a new or revised standard retroactively, resulting in the restatement of prior period financial statements. Any change in reported earnings as a result of the foregoing could have a material adverse effect on Santander UK's future financial results and financial condition.

Regulation of the Santander UK group

As a financial services group, Santander UK is subject to extensive financial services laws, regulations, administrative actions and policies in the UK and in each other location in which Santander UK operates. This intensive approach to supervision is maintained in the UK by the PRA and the FCA. As well as being subject to UK regulation, as a result of forming part of the Banco Santander group, Santander UK is also affected by other regulators, such as the Banco de España and the ECB, as well as various legal and regulatory regimes (including the US) that have extra-territorial effect. Extensive legislation and implementing regulations affecting the financial services industry have recently been adopted in regions that directly or indirectly affect Santander UK's business, including Spain, the US, the EU and other jurisdictions. In the UK and elsewhere, there is continuing political, competitive and regulatory scrutiny of the banking industry. Political involvement in the regulatory process, in the behaviour and governance of the UK banking sector and in the major financial institutions in which the UK government has a direct financial interest is likely to continue.

**Approach of the Financial Conduct Authority (FCA)**

As per the FSMA (as amended by the Financial Services Act 2012), the FCA has a strategic objective to ensure that the relevant markets function well. In support of this, the FCA has three operational objectives: to protect consumers from bad conduct, to protect and enhance the integrity of the UK financial system and to promote effective competition in the interests of consumers.

The FCA Handbook sets out rules and guidance across a range of conduct issues with which financial institutions are required to comply including high level principles of business and detailed conduct of business standards and reporting standards.

**Regulatory approach of the PRA**

As per the Financial Services Act 2012, the PRA has two primary objectives: to promote the safety and soundness of the firms which it regulates and, with respect to insurers, to contribute to the securing of an appropriate degree of protection for policyholders. The PRA has a secondary objective in respect of the promotion of effective competition in the markets for services provided by PRA authorised firms. The PRA's regulatory and supervisory approach incorporates three key characteristics: to take a judgement-based approach, a forward-looking approach, and a focused approach.

The PRA Rulebook includes regulations and guidance relating to capital adequacy and liquidity, among several other things.

**US regulation**

Within the Dodd-Frank Act, the so-called Volcker Rule, prohibits 'banking entities', including the Santander UK group, from engaging in certain forms of proprietary trading or from sponsoring or investing in certain covered funds, in each case subject to certain exemptions, including exemptions permitting foreign banking entities to engage in trading and fund activities that take place solely outside of the US. The Volcker Rule also contains exclusions and certain exemptions for market-making, hedging, underwriting, trading in US government and agency obligations as well as certain foreign government obligations, and also permits ownership interests in certain types of funds to be retained such as new exclusions for credit funds, venture capital funds, family wealth management vehicles and client facilitation vehicles. The Santander UK group has policies, procedures and controls in place designed to achieve compliance with the Volcker Rule.

**The Banking Act 2009**

The special resolution regime set out in the Banking Act 2009 provides HM Treasury, the Bank of England, the PRA and the FCA with a variety of powers for dealing with UK deposit taking institutions (and, in certain circumstances, their holding companies) that are failing or likely to fail, including: (i) to take a bank or bank holding company into temporary public ownership; (ii) to transfer all or part of the business of a bank to a private sector purchaser; or (iii) to transfer all or part of the business of a bank to a bridge bank'. The special resolution regime also comprises a separate insolvency procedure and administration procedure each of which is of specific application to banks. These insolvency and administration measures may be invoked prior to the point at which an application for insolvency proceedings with respect to a relevant institution could be made.

The Financial Services (Banking Reform) Act 2013 further amended the Banking Act 2009 to introduce a UK 'bail-in power' to implement the BRRD, which contains a bail-in power similar to that contained in the Banking Act and requires EU Member States to provide resolution authorities with the power to write down the claims of unsecured creditors of a failing institution and to convert unsecured claims to equity (subject to certain parameters). The UK bail-in power is an additional power available to the UK resolution authorities under the special resolution regime provided for in the Banking Act 2009. This enables them to recapitalise a failed institution by allocating losses to such institution's shareholders and unsecured creditors, subject to the rights of such shareholders and unsecured creditors to be compensated under a bail-in compensation order.

**Competition**

The CMA is the UK's main competition authority responsible for ensuring that competition and markets work well for consumers. In addition, under the Banking Reform Act, as of 1 April 2015, the FCA has the power to enforce against breaches of the Competition Act 1998 and to refer markets to the CMA for in-depth investigation in the areas of financial services in the UK. As of 1 April 2015, the PSR also has an objective and powers equivalent to those of the FCA to promote competition in the payments industry.

**Payments**

Within the UK, the Payment Systems Regulator has mandated that Santander UK builds systems and processes for both Confirmation of Payee as well as the Contingent Reimbursement Model Code (CRM) both of which aim to reduce the level of customer fraud (particularly through our customer's manipulation into making payments known as 'Authorised Push Payment' fraud). Under these standards, Santander UK assumes responsibility for certain categories of customer losses, and inherent failings in system design may lead to fines from regulators and/or compensation being paid to customers. Santander UK also expects to see significant developments in the key UK payment systems architecture - with systems update of the high value CHAPS system through Real Time Gross Settlement (RTGS) renewal as well as the 'New Payments Architecture' for faster payments, BACS and the other lower value retail payment schemes. The Second Payment Services Directive (PSD2) has been implemented within the UK and the UK continues to build upon the requirements within the EBA Regulatory Technical Standards via the Open Banking API industry standard and build. Santander UK has also adapted systems and pricing to comply with other European regulations - including the Second Cross Border Payments Regulation which has required Santander UK to baseline the majority of EEA currency payments against their domestic equivalents in price.

Finally, Santander UK has reviewed its use of European payments systems and processes in light of the end of the UK's transition period with the EU and has concluded that it can remain within the SEPA Payment Scheme and continue to send SEPA Euro Payments via Madrid to EEA beneficiaries. However, as it is not domiciled in the EU, it has needed to exit the other (high value) Euro payment schemes, being EURO1 and Target 2. It has negotiated new arrangements to access those systems via Madrid and a correspondent banking relationship agreement has been agreed and is operational.

**Financial crime**

On 30 May 2018, the Council of EU and the European Parliament amended the Fourth Anti-Money Laundering Directive (the Directive), publishing the amending Directive (EU) No 2018 / 843 (5th AMLD).

The 5th AMLD brought in increased corporate transparency rules, introduced the application of AML rules to firms providing services associated with virtual currencies and further extended enhanced due diligence (EDD) requirements to all transactions with natural persons or legal entities established in third countries identified as high-risk countries (HRTCs) pursuant to Article 9(2) of the Directive.

The UK government transposed the Directive into UK law on 20 December 2019, amending the UK's Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 (MLRs) through the Money Laundering and Terrorist Financing (Amendment) Regulations 2019. The latter came into effect on 10 January 2020 and, among other changes, introduced a requirement to report beneficial ownership discrepancies to Companies House. Further amendments to the MLRs were made by the Money Laundering and Terrorist Financing (Amendment) (EU Exit) Regulations 2020.

On 26 March 2021, HM Treasury published a new statutory instrument, The Money Laundering and Terrorist Financing (Amendment) (High Risk Countries) Regulations 2021 amending the MLRs by replacing references to the European Commission's list of HRTCs (in respect of which EDD and additional specific EDD measures must be taken under the MLRs) with a UK list identified in a new Schedule 3ZA to the MLRs. This was the first exercise of the powers in section 49 of the Sanctions and Anti-Money Laundering Act 2018 (SAMLA). The UK list of HRTCs came into force on 26 March 2021 and has since been amended through The Money Laundering and Terrorist Financing (Amendment)(No.2)(High-Risk Countries) Regulations 2021 coming into force on 13 July 2021, The Money Laundering and Terrorist Financing (Amendment) (No. 3) (High-Risk Countries) Regulations 2021 coming into force on 2 November 2021, Money Laundering and Terrorist Financing (Amendment) (High-Risk Countries) Regulations 2022 coming into force on 29 March 2022, The Money Laundering and Terrorist Financing (High-Risk Countries) (Amendment) (No. 2) Regulations 2022 coming into force on 12 July 2022, and The Money Laundering and Terrorist Financing (High-Risk Countries) (Amendment) (No. 3) Regulations 2022 coming into force on 15 November 2022. These amendments reflect changes to the Financial Action Task Force (FATF) list of jurisdictions under increased monitoring.

In July 2021, the UK government launched two consultations on the MLRs (as amended). The first targeted specific changes to align the UK's AML/CTF regime with recent amendments to FATF standards and introduce certain technical changes. The second was a 'Call for Evidence' examining the effectiveness and future state of the UK's AML/CTF regime. Both consultations closed in October 2021. On 24 June 2022, the UK government published a forward-looking review of the UK's AML/CTF regime in response to the 'Call for Evidence' focusing on systemic effectiveness, regulatory effectiveness and supervisory effectiveness. Following the publication of The Money Laundering and Terrorist Financing (Amendment) Regulations 2022 which came into force on 9 March 2022 and served to make certain time-sensitive updates to ensure the UK continues to meet international standards, and , the UK government published The Money Laundering and Terrorist Financing (Amendment) (No. 2) Regulations 2022 in response to their 2021 consultation, coming into force on 1 September with specific measures coming into force on 1 April 2023. These amendments include amongst others, specific obligations in respect of addressing Proliferation Financing risk and amendments to beneficial ownership discrepancy reporting regime, including discrepancy reporting obligations in respect of the Register of Overseas Entities introduced by the Economic Crime (Transparency and Enforcement) Act 2022 which was quickly moved through Parliament in light of Russia's invasion of Ukraine and came into force in 15 March 2022. Additional key changes introduced by the Economic Crime (Transparency and Enforcement) Act 2022 included strengthening aspects of the Unexplained Wealth Orders regime and increasing the speed at which sanctions designations can be made. On 22 September 2022, the UK government introduced the Economic Crime & Corporate Transparency Bill which aims to deliver long-awaited reforms to tackle economic crime and improve transparency over corporate entities. It is expected that this Bill gains Royal Assent during 2023.

To ensure regulatory continuity post-Brexit, the government introduced SAMLA to provide a legal framework through which it can impose and update sanctions following the UK's departure from the EU. SAMLA grants the UK government the authority to introduce statutory instruments to enable compliance with United Nations (UN) sanctions and other international obligations, and to meet defined discretionary purposes such as promoting national and international peace and security. SAMLA broadly mirrors the EU sanctions regime but enables the UK to act independently by imposing sanctions regulations swiftly without the need to reach a consensus with other EU member states. For example, the UK government introduced the Global Anti-Corruption Sanctions Regulations 2021 which allow the UK government to designate entities and individuals involved in serious corruption around the world. Separately, the Money Laundering and Transfer of Funds (Information) (Amendment) (EU Exit) Regulations 2019 were enacted to ensure that the UK's AML Regime has continued to operate effectively now that the UK has ceased to be a member of the EU.

The possibility of near-term divergence from EU law was reduced by the FCA's Temporary Transitional Power. Under this, a standstill direction was issued which stipulated that until 31 March 2022 and in terms of certain regulatory obligations, firms could continue to comply with the legal framework in place in the UK immediately before 31 December 2020. Financial crime legislation was covered by the standstill direction.

The US government has continued to actively apply and enforce sanctions against individuals, entities and countries. US sanctions are subject to change without warning and may affect Santander UK's ability to transact with certain individuals and entities and to operate in certain jurisdictions.

The UK, EU and US are expected to continue to use sanctions to pursue their foreign policy interests and objectives, and the imposition of new, additional, and/or enhanced sanctions is and will remain unpredictable. Any changes in UK, EU and/or US sanctions could affect Santander UK's business.

The banking sector in the UK continues to be subject to the Suspicious Activity Reporting (SAR) regime laid out in the Proceeds of Crime Act 2002. The regime is one of the key tools to inform law enforcement agencies and the National Crime Agency of suspicious (potentially money laundering or terrorist financing) activity. In 2018, the UK government asked the Law Commission to conduct a review of the legislation underpinning the regime. The review was completed in July 2019 and concluded that the breadth of the legal framework, including the pressure to submit SARs that is driven by individual criminal liability for failing to submit one when 'suspicious', means that the SARs regime suffers from very large reporting volumes.

The UK's SARs Reform Programme, which operates within the confines of the government's Economic Crime Plan 2019-2022, is exploring how banks could, together with government, target their joint efforts to produce and act quickly on higher value intelligence, thereby acting on some of the Law Commission's findings. Anti-corruption continues to be a key focus of the UK Governments approach to economic crime. The Economic Crime (Transparency and Enforcement) Act 2022 which came into force on 15 March 2022 contains provisions which will seek to tackle corruption through increased transparency of overseas ownership of UK land and real estate and the strengthening of UWO's. Anti-corruption remains a topic of global focus, as illustrated by President Biden's 'Protecting Democracy' summit in December 2021 during which the US released its first strategy on Countering Corruption and more recently US National Security Advisor Jake Sullivan's speech at the December 2022 International Anti-Corruption Conference (IACC). Sullivan reiterated President Biden and the US administration's commitment to working with other countries to champion democracy and fight corruption.

Articles of Association

The following is a summary of the Articles of Association (the Articles) of the Company.

Santander UK plc is a public limited company incorporated and registered in England and Wales under the Companies Act 2006, with registered number 2294747. The Articles specifically state and limit the objects of the Company which are therefore restricted.

A Director shall not vote on, or be counted in the quorum in relation to, any resolution of the Directors in respect of any contract in which he has an interest, except if no conflict of interest could reasonably be expected to arise from that interest, or any resolution of the Directors concerning his own appointment, or the settlement or variation of the terms or the termination of his or her appointment. Directors are entitled to such remuneration as the directors determine for their services to the Company as directors and for any other service which they undertake for the Company. Directors may delegate to a person or committee the determination of any fee, remuneration or other benefit which may be paid or provided to any Director. No Director is required to retire by reason of his or her age, nor do any special formalities apply to the appointment or re-election of any Director who is over any age limit. No shareholding qualification for Directors is required.

The Company may issue shares with such rights or restrictions as may be determined by ordinary resolution or, if no such resolution has been passed or so far as the resolution does not make specific provision, as the Directors may decide. The Company may by ordinary resolution declare dividends, and the Directors may decide to declare or pay interim dividends. No dividend may be declared or paid unless it is in accordance with shareholders' respective rights. If dividends are unclaimed for twelve years, the right to the dividend ceases. All dividends or other sums which are payable in respect of shares, and unclaimed after having been declared or become payable, may be invested or otherwise made use of by the Directors for the benefit of the Company until claimed.

Preference shares entitle the holder to receive a preferential dividend payment at a fixed or variable rate, such dividend to be payable on a date determined by the Board prior to the allotment of the shares. The Board will also determine whether these dividend rights are cumulative or non-cumulative. The holders of any series of preference shares will only be entitled to receive notice of and to attend any general meeting of the Company if the preference dividend on the preference shares of such series has not, at the date of the notice of the general meeting, been paid in full in respect of such dividend periods as the Board may prior to allotment determine, in which case the holders of the preference shares will be entitled to speak and/or vote upon any resolution proposed; or, if a resolution is proposed at the general meeting for, or in relation to, the winding up of the Company, or varying, altering or abrogating any of the rights, privileges, limitations or restrictions attached to the preference shares of such series, in which case the holders of the preference shares of such series will be entitled to speak and/or vote only upon such resolution; or in such other circumstances, and upon and subject to such terms, as the Board may determine prior to allotment. Unless the Board determines, prior to allotment, that the series of preference shares shall be non-redeemable, each series shall be redeemable at the option of the Company on any date as the Board may determine prior to the date of allotment. On redemption the Company shall pay the amount due. The formula for calculation of any relevant redemption premium is set out in the Articles of Association.

On a distribution of assets on winding up of the Company or return of capital (other than on a redemption or purchase by the Company of any of its share capital), members holding preference shares shall in respect thereof be entitled to receive, out of the surplus assets remaining after payment of the Company's liabilities, an amount equal to the amount paid up or credited as paid up on the preference shares together with such premium (if any) as may be determined by the Board prior to allotment thereof (and so that the Board may determine that such premium is payable only in specified circumstances).

Ordinary shares are transferable. Holders of ordinary shares are entitled to receive notice of and to attend any general meeting of the Company. Subject to any special terms as to voting upon which any shares may be issued or may for the time being be held, or any suspension or any abrogation of special rights, as set out in the Articles of Association, on a show of hands every member who is present in person at a general meeting of the Company shall have one vote and every proxy present who has been duly appointed by a member shall have one vote. On a poll every member who is present in person or by proxy shall have one vote for every share of which he is the holder.

Subject to the prior rights of holders of preference shares, theCompany pays dividends on its ordinary shares only out of its distributable profits and not out of share capital. Dividends are determined by the Board.

The Company's Articles of Association authorise it to issue redeemable shares, but the Company's ordinary shares are not redeemable. Where the shares are partly paid, the Board may make further calls upon the holders in respect of any sum whether in respect of nominal value or premium that is unpaid on their shares. There are no provisions discriminating against any existing or prospective shareholder as a result of such shareholder owning a substantial number of shares of any class. Subject to the provisions of the UK Companies Act 2006, all or any of the rights attached to any class of shares (whether or not the Company is being wound up) may be varied with the consent in writing of the holders of not less than three-quarters in nominal value of the issued shares of that class or with the sanction of a special resolution passed at a separate general meeting of the holders of those shares. Additional quorum and voting requirements apply to such meeting.

General meetings shall be called by at least 14 clear days' notice (that is, excluding the day of the general meeting and the day on which the notice is given). A general meeting may be called by shorter notice if it is so agreed, in the case of an annual general meeting, by all the shareholders having a right to attend and vote, or in other cases, by a majority in number of the shareholders having a right to attend and vote, being a majority together holding not less than 95% in nominal value of the shares giving the right. The notice shall specify the date, time and place of the meeting and the general nature of the business to be transacted.

There are no restrictions on the rights to own securities for either resident or non-resident shareholders, other than those to which they may be subject as a result of laws and regulations in their home jurisdiction.

Disclosure pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act

Pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012, which added Section 13(r) to the Securities Exchange Act of 1934, as amended (the Exchange Act), an issuer is required to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with individuals or entities designated pursuant to certain Executive Orders. Disclosure is generally required even where the activities, transactions or dealings were conducted in compliance with applicable law.

The following activities are disclosed in response to Section 13(r) with respect to the Banco Santander group and its affiliates. During the period covered by this report:

(a) Santander UK holds seven blocked accounts for five customers that are currently designated by the US under the Specially Designated Global Terrorist (SDGT) sanctions programme. Revenues and profits generated by Santander UK on these accounts in the year ended 31 December 2022 were negligible relative to the overall profits of Banco Santander SA.

(b) Santander Consumer Finance, SA holds through its Belgian branch seven blocked correspondent accounts for an Iranian bank that is currently designated by the US under the SDGT sanctions programme. The accounts have been blocked since 2008. No revenues or profits were generated by the Belgian branch on these accounts in the year ended 31 December 2022.

(c) Santander Brasil holds three blocked accounts for three customers with domicile in Brazil designated by the US under the SDGT sanctions programme. Revenues and profits generated by Santander Brasil on these accounts in the year ended 31 December 2022 were negligible relative to the overall profits of Banco Santander SA.

(d) Santander Consumer Finance, SA also held through its branch in Greece an auto finance loan for a client designated by the US under the SDGT sanctions programme. The relationship was terminated before the year end. Revenues or profits generated by the branch in Greece on this position in the year ended 31 December 2022 were negligible relative to the overall profits of Banco Santander SA.

(e) The Banco Santander group also has certain legacy performance guarantees for the benefit of an Iranian bank that is currently designated by the US under the SDGT sanctions programme (stand-by letters of credit to guarantee the obligations – either under tender documents or under contracting agreements – of contractors who participated in public bids in Iran) that were in place prior to 27 April 2007.

In the aggregate, all of the transactions described above resulted in gross revenues and net profits in the year ended 31 December 2022 which were negligible relative to the overall revenues and profits of the Banco Santander group. The Banco Santander group has undertaken significant steps to withdraw from the Iranian market such as closing its representative office in Iran and ceasing all banking activities therein, including correspondent relationships, deposit taking from Iranian entities and issuing export letters of credit, except for the legacy transactions described above. The Banco Santander group is not contractually permitted to cancel these arrangements without either (i) paying the guaranteed amount (in the case of the performance guarantees), or (ii) forfeiting the outstanding amounts due to it (in the case of the export credits). As such, the Banco Santander group intends to continue to provide the guarantees and hold these assets in accordance with company policy and applicable laws.

New York Stock Exchange (NYSE) Corporate Governance – differences in UK and NYSE corporate governance practice

The Company issues notes in the US from time to time pursuant to a shelf registration statement filed with the SEC. As these notes are listed on the NYSE, the Company is required to comply with NYSE corporate governance standards. Under the NYSE corporate governance standards, the Company must disclose any significant ways in which its corporate governance practices differ from those followed by US companies under the NYSE corporate governance standards. We believe the following to be the significant differences between our current corporate governance practices and those applicable to US companies under the NYSE corporate governance standards.

Under the NYSE corporate governance standards, independent Directors must comprise a majority of the Board. As at 31 December 2022, our Board was comprised of a Chair, (who is also a Non-Executive Director), two Executive Directors and nine Non-Executive Directors. The Chair, William Vereker, and six of the other Non-Executive Directors, (Annemarie Durbin, Ed Giera, Lisa Fretwell, Chris Jones, Mark Lewis and Nicky Morgan), were independent as defined in the NYSE corporate governance standards. The other three Non-Executive Directors (Dirk Marzluf, Antonio Simoes and Pamela Walkden) were not independent according to NYSE corporate governance standards as they are representatives of the ultimate parent company, Banco Santander SA. Lisa Fretwell was appointed as an independent Non-Executive Director, on 1 January 2022.

The NYSE corporate governance standards require that listed US companies have a nominating or corporate governance committee composed entirely of independent Directors and with a written charter addressing certain corporate governance matters. Applicable UK rules do not require companies without equity shares listed on the London Stock Exchange, such as the Company, to have a nominating committee. However, the Company has a Board Nomination Committee, which leads the process for Board appointments. This Committee has written Terms of Reference setting out its role to identify and nominate candidates for Board and Board Committee appointments. As at 31 December 2022, the following Directors made up the Board Nomination Committee: William Vereker (Chair), Annemarie Durbin, Ed Giera and Pamela Walkden. Three of the Directors were independent according to NYSE corporate governance standards. The other Director (Pamela Walkden) was not independent according to the NYSE corporate governance standards as she is a representative of the ultimate parent company, Banco Santander SA.

In addition, the Board is responsible for monitoring the effectiveness of the Company's governance practices and making changes as needed to ensure the alignment of the Company's governance system with current best practices. The Board monitors and manages potential conflicts of interest of management, Board members, shareholders, external advisers and other service providers, including misuse of corporate assets and abuse in related party transactions.

The NYSE corporate governance standards require that listed US companies have a compensation committee composed entirely of independent directors and with a written charter addressing certain corporate governance matters. Under its written Terms of Reference, the Company's Board Remuneration Committee is primarily responsible for overseeing and supervising Santander UK's policies and frameworks covering remuneration and reward. As at 31 December 2022, the following Directors were on the Board Remuneration Committee: Annemarie Durbin (Chair), Ed Giera, Chris Jones and Mark Lewis. All Directors were independent according to NYSE corporate governance standards.

The NYSE corporate governance standards require that listed US companies have an audit committee that satisfies the requirements of Rule 10A-3 under the US Securities Exchange Act of 1934, as amended (Rule 10A-3), with a written charter addressing certain corporate governance matters, and having a minimum of three members who are all independent as defined in Rule 10A-3. As a wholly-owned subsidiary of a parent that satisfies the requirements of Rule 10A-3(c)(2), the Company is exempt from the requirements of Rule 10A-3. However, the Company does have a Board Audit Committee. As at 31 December 2022, the Board Audit Committee was made up of six Non-Executive Directors: Chris Jones (Chair), Annemarie Durban, Lisa Fretwell, Ed Giera, Mark Lewis and Nicky Morgan. All members were independent in 2022 as defined in Rule 10A-3.

The scope of the Board Audit Committee's Terms of Reference as well as the duties and responsibilities of such committee are more limited than that required of audit committees under the NYSE corporate governance standards. For example, the Board Audit Committee does not provide an audit committee report as required by the NYSE corporate governance standards to be included in the Company's annual proxy statement.

The NYSE corporate governance standards require that listed US companies adopt and disclose corporate governance guidelines, including with respect to the qualification, training and evaluation of their Directors. The NYSE corporate governance standards also require that the Board conducts a self-evaluation at least annually to determine whether it and its committees are functioning effectively. The Board has undertaken regular reviews of Board effectiveness primarily through an internal process led by the Chair. During the year the Board considered feedback gained from the 2022 performance evaluations, which concluded that the performance of the Board and its Committees continues to be effective.

A CEO of a US company listed on the NYSE must annually certify that he or she is not aware of any violation by the company of NYSE corporate government standards. In accordance with NYSE corporate governance standards applicable to foreign private issuers, our CEO is not required to provide the NYSE with such an annual compliance certification.

SUMMARY OF LOAN LOSS EXPERIENCE

Loans accounted for on a non-accrual basis are credit impaired loans. We define a loan as in default (i.e. credit impaired) for purposes of calculating ECL if it is more than three months past due, or if we have data to make us doubt they can keep up with their payments i.e. they are unlikely to pay. We classify credit impaired loans as Stage 3. For details of loans classified as Stage 3, see the 'Credit risk' section of the Risk review. Interest income on financial assets that have become credit-impaired (or Stage 3) is calculated by applying the effective interest rate to their amortised cost (i.e. net of the ECL provision).

In 2022 and 2021 there were no material credit impairment charges on loans and advances to banks, non-trading reverse repurchase agreements, other financial assets at amortised cost and financial assets at FVOCI. As a result, the following tables present Loans and Advances to customers only.

The following tables show additional ratios and the components used in their calculation for the years ended 31 December 2022, 2021, and 2020.

The UK's statutory fund of last resort for customers of authorised financial services firms is the Financial Services Compensation Scheme (FSCS). The FSCS can pay compensation to customers if a PRA authorised firm is unable, or likely to be unable to pay claims against it for example by depositors.

The following table shows the amounts of insured and uninsured total deposits and time deposits excluding intercompany deposits at 31 December 2022. The table also shows the amount of time deposits that are uninsured, either because they exceed FSCS compensation limits or because they are otherwise uninsured.

INTEREST RATE SENSITIVITY

Interest rate sensitivity is the relationship between interest rates and net interest income caused by the periodic repricing of assets and liabilities. Our largest administered rate items are residential mortgages and retail deposits, most of which bear interest at variable rates.

We mitigate the impact of interest rate movements on net interest income by repricing our variable rate mortgages and variable rate retail deposits separately, subject to competitive pressures. We also offer fixed-rate mortgages and savings products on which the interest rate is fixed for an agreed period at the start of the contract. We manage the margin on fixed-rate products by using derivatives matching the fixed-rate profiles. We reduce the risk of prepayment by imposing early termination charges if the customers end their contracts early.

We manage the risks from movements in interest rates as part of our overall non-trading position. We do this within limits as set out in the Risk review.

**Changes in net interest income – volume and rate analysis**

The following table shows changes in interest income, interest expense and net interest income, and is presented using asset and liability classifications in the Consolidated Balance Sheet. It allocates the effects between changes in volume and changes in rate. Volume and rate changes have been calculated on the movement in the average balances and the change in the interest rates on average interest-earning assets and average interest-bearing liabilities. The changes caused by movements in both volume and rate have been allocated to rate changes.

SUMMARISED CONSOLIDATED CASH FLOW STATEMENT

---

| | | |
|:---|:---|:---|
| | **2022** | 2021 |
| | **£m** | £m |
| Net cash flows from operating activities | **(2970)** | 10251 |
| Net cash flows from investing activities | **(198)** | 3077 |
| Net cash flows from financing activities | **277** | (10753) |
| **Change in cash and cash equivalents** | **(2891)** | 2575 |

---

A more detailed Consolidated Cash Flow Statement is contained in the Consolidated Financial Statements.

The major activities and transactions that affected cash flows in 2022 and 2021 were as follows:

In 2022, the net cash outflows from operating activities of £2,970m resulted from outflows generated from an increase in loans and advances to banks and customers, and a decrease in deposits by banks and customers and repurchase agreements, partially offset by net cash inflows from an decrease in reverse repurchase agreements. The net cash outflows from investing activities of £198m mainly reflected the net disposal of certain asset backed securities as part of normal liquid asset portfolio management. The net cash inflows from financing activities mainly reflected net cash inflows relating to debt securities in issue. These resulted in cash and cash equivalents decreasing by £2,891m in the year.

In 2021, the net cash inflows from operating activities of £10,251m resulted from net cash inflows generated from profits in the year and higher customer deposits, offset by additional retail and corporate lending. The net cash inflows from investing activities of £3,077m mainly reflected the net disposal of certain asset backed securities as part of normal liquid asset portfolio management. The net cash outflows from financing activities mainly reflected net cash outflows relating to debt securities in issue. These resulted in cash and cash equivalents increasing by £2,575m in the year.

**Cash flow requirements**

For details of our cash flow requirements over the next 12 months and in the longer term and how we plan to meet them, see the Liquidity risk section of the Risk review.

**Material cash requirements**

Our material commitments under commercial contracts at 31 December 2022 were as follows:

–For cash flows and maturities relating to Derivatives, Deposits by customers, Deposits by banks, Debt securities in issue, Subordinated liabilities and Lease obligations, see Note 40 to the Consolidated Financial Statements. The maturities of financial liabilities and off-balance sheet commitments table analyses the maturities of the cash flows based on the remaining period to the contractual maturity date at the balance sheet date. In practice, the behavioural profiles of many liabilities show more stability and longer maturity than their contractual maturity. This is especially true of many types of retail and corporate deposits that, while they may be repayable on demand or at short notice, have shown good stability even in times of stress. For further details, see the Liquidity risk section of the Risk review.

–For details of cash flows and maturities relating to Retirement benefit obligations including employer contributions and funding see Note 30 to the Consolidated Financial Statements.

–Purchase obligations: We have entered into outsourcing contracts where, in some cases, there is no minimum specified spending requirement. In these cases, anticipated spending volumes have been included in purchase obligations. Total purchase obligations, all of which are due within 1 year, totalled £469m.

Taxation for US investors

The following is a summary, under current law, of the main UK tax considerations relating to the beneficial ownership by a US taxpayer of the shares of the Company. This summary is provided for general guidance and does not address investors that are subject to special rules or that do not hold the shares as capital assets. US residents should consult their local tax advisers, particularly in connection with any potential liability to pay US taxes on disposal, lifetime gift or bequest of their shares.

**UK taxation on dividends**

Under UK law, income tax is not withheld from dividends paid by UK companies. Shareholders, whether resident in the UK or not, receive the full amount of the dividend actually declared.

**UK taxation on capital gains**

Under UK law, when you sell shares you may be liable to pay either capital gains tax or corporation tax on chargeable gains. However, if you are either:

–An individual who is not resident in the UK or

–A company which is not resident in the UK,

you will not be liable to UK tax on any capital gains made on disposal of your shares. The exception is if the shares are held in connection with a trade or business that is conducted in the UK through a branch or agency (for capital gains tax purposes) or a permanent establishment (for corporation tax purposes).

**UK inheritance tax**

Under the current estate and gift tax convention between the US and the UK, shares held by an individual shareholder who is:

–Domiciled for the purposes of the convention in the US and

–Is not for the purposes of the convention a national of the UK will not be subject to UK inheritance tax on:

–The individual's death or

Glossary of financial services industry terms

---

| | |
|:---|:---|
| **Term** | **Definition** |
| **Active customers** | Active customers are defined as those having an open account, with more than a set minimum balance along with certain specified transactions in the prior month. |
| **Alternative performance measures (APMs)** | A financial measure of historical or future financial performance, financial position or cashflows, other than a financial measure defined or specified under International Financial Reporting Standards. |
| **Arrears** | Customers are said to be in arrears when they are behind in fulfilling their obligations with the result that an outstanding loan is unpaid or overdue. Such a customer is also said to be in a state of delinquency. When a customer is in arrears, his entire outstanding balance is said to be delinquent, meaning that delinquent balances are the total outstanding loans on which payments are overdue. |
| **Asset Backed Securities (ABS)** | Securities that represent an interest in an underlying pool of referenced assets. The referenced pool can comprise any assets which attract a set of associated cash flows but are commonly pools of residential or commercial mortgages but could also include leases, credit card receivables, motor vehicles or student loans. |
| **Balance weighted Loan to Value (LTV) ratio** | Balance weighted LTV = (Loan 1 balance x (Loan 1 Balance/Loan 1 latest property valuation) + (Loan 2 balance x (loan 2 balance/Loan 2 latest property valuation)+ ...) /(Loan 1 balance + Loan 2 balance +...) |
| **UK Bank Levy** | The government levy that applies to certain UK banks, UK building societies and the UK operations of foreign banks from 1 January 2011. The levy is payable based on a percentage of the chargeable equity and liabilities of the bank at the balance sheet date. |
| **Basel III** | In December 2010, the Basel Committee on Banking Supervision issued the Basel III rules text, which presents the details of strengthened global regulatory standards on bank capital adequacy and liquidity. The standards were implemented in the EU in January 2014. |
| **Basis point (bp)** | One hundredth of a per cent (i.e. 0.01%), so 100 basis points is 1%. Used in quoting movements in interest rates or yields on securities. |
| **Brexit** | The withdrawal of the United Kingdom from the European Union. |
| **Business Banking** | Division, managed under Retail Banking, serving enterprises with a turnover of up to £6.5m per annum. |
| **Colleague engagement** | Colleague engagement is measured on annual basis in the Group Engagement Survey (GES), conducted by Mercer for Banco Santander. Results are benchmarked against other firms in the UK financial sector and other high performing firms. |
| **Commercial Paper** | An unsecured promissory note issued to finance short-term credit needs. It specifies the face amount paid to investors on the maturity date. Commercial paper can be issued as an unsecured obligation of Santander UK and is usually issued for periods ranging from one week up to nine months. However, the depth and reliability of some CP markets means that issuers can repeatedly roll over CP issuance and effectively achieve longer term funding. CP can be issued in a range of denominations and can be discounted or interest-bearing. |

This is a useful measure of the relationship between the size of the credit impairment charge and the book size which investors use as a proxy to compare relative credit risk. |
| **Countercyclical capital buffer** | A capital buffer required under Basel III to ensure that capital requirements take account of the macro-financial environment in which banks operate. |
| **Counterparty credit risk** | The risk that the counterparty to a transaction may default before completing the satisfactory settlement of the transaction. |

| **Term** | **Definition** |
| **Capital Requirements Directive IV (CRD IV)** | An EU legislative package covering prudential rules for banks, building societies and investment firms. |
| **Currency swap** | An arrangement in which two parties exchange specific principal amounts of different currencies at inception and subsequently interest payments on the principal amounts. Often, one party will pay a fixed interest rate, while the other will pay a floating exchange rate (though there are also fixed-fixed and floating-floating arrangements). At the maturity of the swap, the principal amounts are usually re-exchanged. |
| **Customer funding gap** | Customer loans less customer deposits. |
| **Debt restructuring** | This occurs when the terms and provisions of outstanding debt agreements are changed. This is often done in order to improve cash flow and the ability of the borrower to repay the debt. It can involve altering the repayment schedule as well as reducing the debt or interest charged on the loan. |
| **Debt securities** | Transferable instruments creating or acknowledging indebtedness. They include debentures, bonds, certificates of deposit, notes and commercial paper. The holder of a debt security is typically entitled to the payment of principal and interest, together with other contractual rights under the terms of the issue, such as the right to receive certain information. Debt securities are generally issued for a fixed term and redeemable by the issuer at the end of that term. Debt securities can be secured or unsecured. |
| **Debt securities in issue** | Transferable certificates of indebtedness of the Santander UK group to the bearer of the certificates. These are liabilities of the Santander UK group and include commercial paper, certificates of deposit, bonds, and medium-term notes. |
| **Default** | Financial assets in default represent those that are at least 90 days past due in respect of principal or interest and/or where the assets are otherwise considered to be unlikely to pay, including those that are credit impaired. |
| **Default at proxy origination** | IFRS 9 requires us to compare lifetime probability of default at origination with our view of lifetime probability of default now. If we do not have data at origination, then a proxy origination is defined. |
| **Defined benefit obligation** | The present value of expected future payments required to settle the obligations of a defined benefit plan resulting from employee service. |
| **Defined benefit plan** | A pension plan that defines an amount of pension benefit to be provided, usually as a function of one or more factors such as age, years of service or compensation. The employer's obligation can be more or less than its contributions to the fund. |
| **Defined contribution plan** | A pension plan under which the Santander UK group pays fixed contributions as they fall due into a separate entity (a fund) and will have no legal or constructive obligations to pay further contributions, i.e. the employer's obligation is limited to its contributions to the fund. |
| **Derivative** | A contract or agreement whose value changes with changes in an underlying index such as interest rates, foreign exchange rates, share prices or indices and which requires no initial investment or an initial investment that is smaller than would be required for other types of contracts with a similar response to market factors. The principal types of derivatives are: swaps, forwards, futures and options. |
| **Economic capital** | An internal measure of the minimum equity and preference capital required for the Santander UK group to maintain its credit rating based upon its risk profile. |
| **Effective tax rate** | The tax on profit/(losses) on ordinary activities as a percentage of profit/(loss) on ordinary activities before taxation. |
| **Energy performance certificate (EPC)** | A scheme to summarise the energy efficiency of buildings and apply a rating between A – G. |
| **Everyday Banking** | Provides banking services and unsecured lending to individuals and small businesses as well alongside wealth management for high-net-worth clients. |
| **Expected credit loss (ECL)** | Represents what the credit risk is likely to cost us either over the next 12 months on qualifying exposures, or defaults over the lifetime of the exposure where there is evidence of a significant increase in credit risk since origination. |
| **Expected loss** | The product of the probability of default, exposure at default and loss given default. We calculate each factor in accordance with CRD IV and include direct and indirect costs. We base them on our risk models and our assessment of each customer's credit quality. |
| **Exposure at default (EAD)** | The maximum loss that a financial institution might suffer if a borrower, counterparty or group defaults on their obligations or assets and off-balance sheet positions have to be realised. |

| **Term** | **Definition** |
| **Fair value adjustment** | An adjustment to the fair value of a financial instrument which is determined using a valuation technique (level 2 and level 3) to include additional factors that would be considered by a market participant that are not incorporated within the valuation model. |
| **Financial Conduct Authority (FCA)** | The Financial Conduct Authority is a financial regulatory body in the United Kingdom. |
| **Financial Services Compensation Scheme (FSCS)** | The Financial Services Compensation Scheme is the UK's statutory deposit insurance and investors compensation scheme for customers of authorised financial services firms.  |
| **First / Second Charge** | First charge (also known as first lien): debt that places its holder first in line to collect compensation from the sale of the underlying collateral in the event of a default on the loan. Second charge (also known as second lien): debt that is issued against the same collateral as a higher charge debt but that is subordinate to it. In the case of default, compensation for this debt will only be received after the first charge has been repaid and thus represents a riskier investment than the first charge. |
| **Follow-on Rate (FoR)** | A mortgage product that tracks and is directly linked to the Bank of England base rate. |
| **Forbearance** | Forbearance takes place when a concession is made on the contractual terms of a loan in response to an obligor's financial difficulties. |

| **Homes** | Homes provides prime UK mortgage lending to owner occupiers and buy-to-let landlords with small portfolios. |
| **Impairment loss allowance (Loan loss allowance)** | An impairment loss allowance held on the balance sheet as a result of the raising of a charge against profit for an expected credit loss in the lending book. An impairment loss allowance may be either individual or collective. |
| **Individually assessed loan impairment provisions** | Impairment is measured individually for assets that are individually significant. For these assets, the Santander UK group measures the amount of the impairment loss as the difference between the carrying amount of the asset or group of assets and the present value of the estimated future cash flows from the asset or group of assets discounted at the original effective interest rate of the asset. |
| **Internal Capital Adequacy Assessment Process (ICAAP)** | The Santander UK group's own assessment of its regulatory capital requirements, as part of CRD IV. It takes into account the regulatory and commercial environment in which the Santander UK group operates, the Santander UK group's Risk Appetite, the management strategy for each of the Santander UK group's material risks and the impact of appropriate adverse scenarios and stresses on the Santander UK group's capital requirements. |
| **Internal Liquidity Adequacy Assessment Process (ILAAP)** | The Santander UK group's own assessment of the prudent level of liquidity that is consistent with the Santander UK group's LRA. It documents and demonstrates the Santander UK group's overall liquidity adequacy – an appropriate level of liquid resources, a prudent funding profile and comprehensive management and control of liquidity and funding risks. |
| **Internal ratings-based approach (IRB)** | The Santander UK group's method, under the CRD IV framework, for calculating credit risk capital requirements using the Santander UK group's internal Probability of Default models but with supervisory estimates of Loss Given Default and conversion factors for the calculation of Exposure at Default. |

|:---|:---|
| **Term** | **Definition** |
| **Level 1** | The fair value of these financial instruments is based on unadjusted quoted prices for identical assets or liabilities in an active market that the Santander UK group has the ability to access at the measurement date. |
| **Level 2** | The fair value of these financial instruments is based on quoted prices in markets that are not active or quoted prices for similar assets or liabilities, recent market transactions, inputs other than quoted market prices for the asset or liability that are observable either directly or indirectly for substantially the full term, and inputs to valuation techniques that are derived principally from or corroborated by observable market data through correlation or other statistical means for substantially the full term of the asset or liability. |
| **Level 3** | The fair value of these financial instruments is based on inputs to the pricing or valuation techniques that are significant to the overall fair value measurement of the asset or liability are unobservable. |
| **Liquid assets coverage of wholesale funding of less than one year** | LCR eligible liquidity pool divided by wholesale funding with a residual maturity of less than one year. |
| **Liquidity Coverage Ratio (LCR)** | The LCR is intended to ensure that a bank maintains an adequate level of unencumbered, high quality liquid assets which can be used to offset the net cash outflows the bank could encounter under a short-term significant liquidity stress scenario. |
| **LCR eligible liquidity pool** | Assets eligible for inclusion in the LCR as high-quality liquid assets. The LCR eligible liquidity pool also covers both Pillar 1 and Pillar 2 risks. |
| **Loan to value ratio (LTV)** | The amount of a first mortgage charge as a percentage of the total appraised value of real property. The LTV ratio is used in determining the appropriate level of risk for the loan and therefore the price of the loan to the borrower. LTV ratios may be expressed in a number of ways, including origination LTV and indexed LTV. |
| **Loss Given Default (LGD)** | The fraction of Exposure at Default that will not be recovered following default. LGD comprises the actual loss (the part that is not recovered), together with the economic costs associated with the recovery process. It is calculated as the expected loss divided by EAD for each month of the forecast period. We base LGD on factors that impact the likelihood and value of any subsequent write-offs, which vary according to whether the product is secured or unsecured. If the product is secured, we take into account collateral values as well as the historical discounts to market/book values due to forced sales type. |
| **Master netting agreement** | An industry standard agreement which facilitates netting of transactions (such as financial assets and liabilities including derivatives) in jurisdictions where netting agreements are recognised and have legal force. The netting arrangements do not generally result in an offset of balance sheet assets and liabilities for accounting purposes, as transactions are usually settled on a gross basis. |
| **Medium-Term Funding (MTF)** | Shown at a sterling equivalent value. Consists of senior debt issuance, asset-backed issuance (including securitisation and covered bond issuance) and structured issuance (including firm financing repurchase agreements). |
| **Medium-Term Notes (MTNs)** | Corporate notes (or debt securities) continuously offered by a company to investors through a dealer. Investors can choose from differing maturities, ranging from nine months to 30 years. They can be issued on a fixed or floating coupon basis or with an exotic coupon; with a fixed maturity date (non-callable) or with embedded call or put options or early repayment triggers. MTNs are most generally issued as senior, unsecured debt. |
| **Minimum requirement for own funds and eligible liabilities (MREL)** | A requirement under the Bank Recovery and Resolution Directive for EU resolution authorities to set a minimum requirement for own funds and eligible liabilities for banks, implementing the Financial Stability Board's Total Loss Absorbing Capacity (TLAC) standard. The purpose of MREL is to help ensure that when banks, building societies and investment firms fail, that failure can be managed in an orderly way while minimising risks to financial stability, disruption to critical economic functions, and risks to public funds. |
| **Mortgages** | Refers to residential and buy to let retail mortgages only and excludes social housing and commercial mortgage properties. |
| **Mortgage-Backed Securities (MBS)** | Securities that represent interests in groups of mortgages, which may be on residential or commercial properties. Investors in these securities have the right to cash received from future mortgage payments (interest and / or principal). When the MBS references mortgages with different risk profiles, the MBS is classified according to the highest risk class. |
| **Net fee and commission income** | Fee and commission income minus other fees paid that are not an integral part of the effective interest rate. For retail and corporate products, fee and commission income consists principally of collection services fees, commission on foreign currencies, commission and other fees received from retailers for processing credit card transactions, fees received from other credit card issuers for providing cash advances for their customers through the Santander UK group's branch and ATM networks, annual fees payable by credit card holders and fees for non-banking financial products. |
| **Net interest income** | The difference between interest received on assets and interest paid on liabilities. |
| **Net Interest Margin (NIM)** | Net interest income as a percentage of average interest-earning assets. |

| **Term** | **Definition** |
| **Net Stable Funding Ratio (NSFR)** | The ratio of available stable funding resources to stable funding requirements over a one-year time horizon, assuming a stressed scenario. The Basel III rules require this ratio to be over 100%. |
| **Over the counter (OTC) derivatives** | Contracts that are traded (and privately negotiated) directly between two parties, without going through an exchange or other intermediary. They offer flexibility because, unlike standardised exchange-traded products, they can be tailored to fit specific needs. |
| **Own credit** | The effect of the Santander UK group's own credit standing on the fair value of financial liabilities. |
| **Past due** | A financial asset such as a loan is past due when the counterparty has failed to make a payment when contractually due. |
| **Payment holiday** | A period in which a customer has relief from making repayments on a loan. Also known as a payment deferral. |
| **People Supported** | People supported through our charity partnerships and sponsored programmes. Employee volunteer activities are organised through our flagship Discovery Project programme, the Santander Foundation and Santander Universities. |
| **Pillar 1** | The first pillar of the Basel III approach which provides the approach to the calculation of the minimum capital requirements. This is 8% of the bank's risk-weighted assets. |
| **Pillar 2** | The part of the CRD IV Accord which sets out the process by which a bank should review its overall capital adequacy and the processes under which the supervisors evaluate how well financial institutions are assessing their risks and take appropriate actions in response to the assessments. |
| **Pillar 3** | The part of the CRD IV Accord which sets out the disclosure requirements for firms to publish details of their risks, capital and risk management. The aims are greater transparency and strengthening market discipline. |
| **Prime / prime mortgage loans** | A US description for mortgages granted to the most creditworthy category of borrowers. |
| **Probability of default (PD)** | The likelihood of a borrower defaulting in the following month, assuming it has not closed or defaulted since the reporting date. For each month in the forecast period, we estimate the monthly PD from a range of factors. These include the current risk grade for the exposure, which becomes less relevant further into the forecast period, as well as the expected evolution of the account risk with maturity and factors for changing economics. We support this with historical data analysis. |
| **Prudential Regulation Authority (PRA)** | The UK financial services regulator formed as one of the successors to the FSA. The PRA is part of the Bank of England and is responsible for the prudential regulation and supervision of banks, building societies, credit unions, insurers and major investment firms. It sets standards and supervises financial institutions at the level of the individual firm. |
| **Regulatory capital** | The amount of capital that the Santander UK group holds, determined in accordance with rules established by the UK PRA for the consolidated Santander UK group and by local regulators for individual Santander UK group companies. |
| **Repurchase agreement (Repo)** | In a sale and repurchase agreement one party, the seller, sells a financial asset to another party, the buyer, under commitments to reacquire the asset at a later date. The buyer at the same time agrees to resell the asset at the same later date. From the seller's perspective such agreements are securities sold under repurchase agreements (repos) and from the buyer's securities purchased under commitments to resell (reverse repos). |
| **Residential Mortgage-Backed Securities (RMBS)** | Securities that represent interests in a group of residential mortgages. Investors in these securities have the right to cash received from future mortgage payments (interest and / or principal). |
| **Retail deposit spread** | Retail Banking customer deposit spreads against the relevant swap rate or LIBOR. Retail Banking customer deposits include savings and bank accounts for personal and business banking customers. |
| **Risk Appetite** | The level of risk (types and quantum) that the Santander UK group is willing to accept (or not accept) to safeguard the interests of shareholders whilst achieving business objectives. |
| **Risk-weighted assets (RWA)** | A measure of a bank's assets adjusted for their associated risks. Risk weightings are established in accordance with the Basel Capital Accord as implemented by the PRA. |
| **Securitisation** | A process by which a group of assets, usually loans, are aggregated into a pool, which is used to back the issuance of new securities. A company sells assets to a structured entity which then issues securities backed by the assets, based on their value. This allows the credit quality of the assets to be separated from the credit rating of the original company and transfers risk to external investors. Assets used in securitisations include mortgages to create mortgage-backed securities. Santander UK has established securitisation structures as part of its funding and capital management activities. |

<sup>(1)&nbsp;&nbsp;&nbsp;&nbsp;</sup>"Tax Redemption" means that we have the right to redeem the applicable series of debt securities on the terms described below under "*Tax Redemption*."

<sup>(2)&nbsp;&nbsp;&nbsp;&nbsp;</sup>The events of default described below under "*Events of Default*" are applicable to the relevant series of debt securities.

------

*The summary set out below of the general terms and provisions of our debt securities does not purport to be complete and is subject to and qualified by reference to, all of the definitions and provisions of the relevant indenture (as listed in the table above), any supplement to the relevant indenture and the form of the instrument representing each series of debt securities. Certain terms, unless otherwise defined here, have the meaning given to them in the relevant indenture.*

**General**

The 4.000% Notes due 2024 were issued under an indenture dated as of April 27, 2011, entered into between Abbey National Treasury Services plc ("ANTS") as issuer, Santander UK as guarantor and The Bank of New York Mellon as trustee (the "2011 Senior Indenture"). Effective June 1, 2016, Santander UK was substituted for, and bound by every obligation of, ANTS under the 2011 Senior Indenture, and ANTS was released from its liabilities under the 2011 Senior Indenture and is no longer a party to the 2011 Senior Indenture.

The 2.875% Notes due 2024 and the 2.100% Notes due 2023 were issued under an indenture dated as of September 29, 2016, entered into between us and Citibank, N.A., as trustee (as successor to Wells Fargo Bank, National Association pursuant to an agreement of resignation, appointment and acceptance dated April 19, 2021 among us, the trustee and Wells Fargo Bank, National Association), (the "2016 Senior Indenture").

The 4.000% Notes due 2024, the 2.875% Notes due 2024 and the 2.100% Notes due 2023 are referred to herein as the "debt securities."

The 2011 Senior Indenture and the 2016 Senior Indenture, and any respective supplements thereto, are referred to herein individually as an "indenture" and collectively as the "indentures." The terms of the debt securities include those stated in the relevant indenture and any supplements thereto, and those terms made part of the relevant indenture by reference to the U.S. Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). Each series of debt securities listed in the table above was issued pursuant to an effective registration statement and a related prospectus and prospectus supplement setting forth the terms of the relevant series of debt securities.

The indentures do not limit the amount of debt securities that we may issue. We may issue debt securities in one or more series. We may, without the consent of the holders of the debt securities of any series, issue additional debt securities, having the same ranking and same interest rate, maturity date, redemption terms and other terms as the debt securities previously described in the relevant prospectus. In respect of the debt securities issued under the 2011 Senior Indenture, we may issue additional debt securities, provided however that such additional debt securities must be fungible with the applicable series of debt securities for U.S. federal income tax purposes. In respect of the debt securities issued under the 2016 Senior Indenture, we may issue additional debt securities, provided however that such additional debt securities shall be issued under a separate CUSIP, Common Code and/or ISIN number unless the additional debt securities are issued pursuant to a "qualified reopening" of the applicable debt securities offered by the relevant prospectus supplement, are otherwise treated as part of the same "issue" of debt instruments as the debt securities offered by the relevant prospectus supplement, or the debt securities offered in the relevant prospectus supplement and the additional debt securities are issued with no more than a de minimis amount of original issue, discount, in each case for U.S. federal income tax purposes.

The debt securities are not secured by any assets or property of Santander UK or any of its subsidiaries or affiliates.

Holders of debt securities have no voting rights except those described under the heading "Modification and Waiver" below.

The debt securities are not subject to any sinking fund.

**Interest**

The relevant interest rates and interest payment dates of the debt securities are set out in the table above.

Interest on the debt securities is computed on the basis of a 360-day year of twelve 30-day months.

**Payments**

If any scheduled interest payment date for the debt securities would fall on a day that is not a Business Day (as defined below), then the interest payment date will be postponed to the next succeeding business day, but no additional interest shall accrue and be paid unless we fail to make payment on such next succeeding business day. "Business Day" means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions in the City of New York or London, England are authorized or required by law, regulation or executive order to close.

Initial settlement for the debt securities will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC's Same-Day Funds Settlement System.

**Ranking**

Our debt securities constitute our direct, unconditional, unsecured and unsubordinated obligations ranking pari passu without preference among themselves, with all our other outstanding unsecured and unsubordinated obligations, present and future, except such obligations as are preferred by operation of law.

**No Set-off**

In respect of the debt securities issued under the 2011 Senior Indenture, by accepting each debt security, each holder will be deemed to have waived any right of set-off, counterclaim or combination of accounts with respect to the debt securities or the applicable indenture that they might otherwise have against us, whether before or during our winding up.

In respect of debt securities issued under the 2016 Senior Indenture, subject to applicable law, no holder of debt securities may exercise, claim or plead any right of set-off, compensation or retention in respect of any amount owed to it by us arising under or in connection with the debt securities or the relevant indenture, and each holder of the debt securities shall, by virtue of being the holder of the debt securities, be deemed to have waived all such rights of set-off, compensation or retention. Notwithstanding the preceding sentence, if any of the amounts owing to any holder of the applicable series of debt securities by us is discharged by set-off, such holder shall, unless such payment is prohibited by law, immediately pay us an amount equal to the amount of such discharge or, in the event of our winding-up or administration, the liquidator or administrator, as appropriate, and, until such time as payment is made, shall hold an amount equal to such

------

amount in trust for us, or the liquidator or administrator, as appropriate and accordingly any such discharge shall be deemed not to have taken place.

**Redemption**

**Tax Redemption** 

We will have the option to redeem the debt securities of any series as a whole upon not less than 30 nor more than 60 days' notice to each holder of debt securities, on any interest payment date, at a redemption price equal to 100% of their principal amount together with any accrued but unpaid payments of interest, to the redemption date, or, in the case of discount securities, their accreted face amount, if we determine that as a result of a change in or amendment to the laws or regulations of any taxing jurisdiction, including any treaty to which such taxing jurisdiction is a party, or a change in an official application or interpretation of those laws or regulations, including a decision of any court or tribunal, which becomes effective on or after the issue date of the relevant series of debt securities:

–in making any payments, on the particular series of debt securities, we have paid or will or would on the next interest payment date be required to pay Additional Amounts (as defined below);

–payments, on the next interest payment date in respect of any of the series of debt securities, has been or would be treated as a "distribution," in each case within the meaning of Section 1000 of the Corporation Tax Act 2010 of the United Kingdom, or any statutory modification or re- enactment of that act; or

–on the next interest payment date we were not or would not be entitled to claim a deduction in respect of the payments in computing our UK taxation liabilities, or the value of the deduction to us would be materially reduced.

**Payment of Additional Amounts**

*Debt securities issued under the 2011 Senior Indenture*

Under the terms of the debt securities issued under the 2011 Senior Indenture, amounts to be paid by us on the applicable series of debt securities will be made without deduction or withholding for, or on account of, any and all present and future income, stamp and other taxes, levies, imposts, duties, charges, fees, deductions or withholdings now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of the country in which we are organized or any political subdivision or authority thereof or therein having the power to tax (the "taxing jurisdiction"), unless such deduction or withholding is required by fiscal or other laws, regulations and directives. If at any time a taxing jurisdiction requires us to make such deduction or withholding, we will pay additional amounts, with respect to the principal of, interest and any other payments on, the debt securities ("Additional Amounts") that are necessary in order that the net amounts paid to the holders of those debt securities, after the deduction or withholding, shall equal the amounts which would have been payable on that series of debt securities if the deduction or withholding had not been required. However, this will not apply to any such amount that would not have been payable or due but for the fact that:

(i) the holder or the beneficial owner of the debt securities is a domiciliary, national or resident of, or engaging in business or maintaining a permanent establishment or physically present in, a taxing jurisdiction or otherwise having some connection with the taxing jurisdiction other than the holding or ownership of a debt security, or the collection of any payment of, or in respect of, the principal of, or any interest or other payment on, any debt security of the relevant series;

(ii) except in the case of a winding-up in the UK, the relevant debt security is presented (where presentation is required) for payment in the UK;

(iii) the relevant debt security is presented (where presentation is required) for payment more than 30 days after the date payment became due or was provided for, whichever is later, except to the extent that the holder would have been entitled to the Additional Amounts on presenting the debt security for payment at the close of that 30-day period;

(iv) the holder or the beneficial owner of the relevant debt security or the beneficial owner of any payment of or in respect of principal of, or any interest or other payment on, the debt security failed to comply with a request by us or our liquidator or other authorized person addressed to the holder (x) to provide information concerning the nationality, residence or identity of the holder or the beneficial owner, or (y) to make any declaration or other similar claim to satisfy any information requirement, which, in the case of (x) or (y) is required or imposed by a statute, treaty, regulation or administrative practice of a taxing jurisdiction as a precondition to exemption from all or part of the tax, assessment or other governmental charge;

(v) the withholding or deduction is imposed on a payment to or for the benefit of an individual and is required to be made pursuant to European Council Directive 2003/48/EC, as amended, or any law implementing or complying with, or introduced in order to conform to, such directive; and

(vi) the relevant debt security is presented (where presentation is required) for payment by or on behalf of a holder who would have been able to avoid such withholding or deduction by presenting (where presentation is required) the relevant debt security to another paying agent in a member state of the European Union; or

(vii) any combination of the above items;

nor shall Additional Amounts be paid with respect to the principal of, premium, if any, and any interest on, the debt securities to any holder who is a fiduciary or partnership or settlor with respect to such fiduciary or a member of such partnership other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of any taxing jurisdiction to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts, had it been the holder. For the avoidance of doubt, all payments in respect of the debt securities will be made subject to any withholding or deduction required pursuant to any fiscal or other laws, regulations and directives, including FATCA, and we shall not be required to pay Additional Amounts with respect to the principal of, interest and any other payments on, the debt securities on account of any such deduction or withholding required pursuant to FATCA.

*Debt securities issued under the 2016 Senior Indenture*

Under the terms of the debt securities issued under the 2016 Senior Indenture, amounts to be paid by us on the applicable series of debt securities will be made without deduction or withholding for, or on account of, any and all present and future income, stamp and other taxes,

------

levies, imposts, duties, charges, fees, deductions or withholdings now or hereafter imposed, levied, collected, withheld or assessed by or on behalf of the country in which we are organized or any political subdivision or authority thereof or therein having the power to tax (the "taxing jurisdiction"), unless such deduction or withholding is required by fiscal or other laws, regulations and directives. If at any time a taxing jurisdiction requires us to make such deduction or withholding, we will pay additional amounts, with respect to the principal of, interest and any other payments on, the debt securities ("Additional Amounts") that are necessary in order that the net amounts paid to the holders of those debt securities, after the deduction or withholding, shall equal the amounts which would have been payable on that series of debt securities if the deduction or withholding had not been required. However, this will not apply to any such amount that would not have been payable or due but for the fact that:

(i) the holder or the beneficial owner of the debt securities is a domiciliary, national or resident of, or engaging in business or maintaining a permanent establishment or physically present in, a taxing jurisdiction or otherwise having some connection with the taxing jurisdiction other than the holding or ownership of a debt security, or the collection of any payment of, or in respect of, the principal of, or any interest or other payment on, any debt security of the relevant series;

(ii) except in the case of a winding-up in the UK, the relevant debt security is presented (where presentation is required) for payment in the UK;

(iii) the relevant debt security is presented (where presentation is required) for payment more than 30 days after the date payment became due or was provided for, whichever is later, except to the extent that the holder would have been entitled to the Additional Amounts on presenting the debt security for payment at the close of that 30-day period;

(iv) the holder or the beneficial owner of the relevant debt security or the beneficial owner of any payment of or in respect of principal of, or any interest or other payment on, the debt security failed to comply with a request by us or our liquidator or other authorized person addressed to the holder (x) to provide information concerning the nationality, residence or identity of the holder or the beneficial owner, or (y) to make any declaration or other similar claim to satisfy any information requirement, which, in the case of (x) or (y) is required or imposed by a statute, treaty, regulation or administrative practice of a taxing jurisdiction as a precondition to exemption from all or part of the tax, assessment or other governmental charge; or

(v) any combination of the above items;

nor shall Additional Amounts be paid with respect to the principal of, premium, if any, and any interest on, the debt securities to any holder who is a fiduciary or partnership or settlor with respect to such fiduciary or a member of such partnership other than the sole beneficial owner of such payment to the extent such payment would be required by the laws of any taxing jurisdiction to be included in the income for tax purposes of a beneficiary or partner or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner who would not have been entitled to such Additional Amounts, had it been the holder. For the avoidance of doubt, all payments in respect of the debt securities will be made subject to any withholding or deduction required pursuant to any fiscal or other laws, regulations and directives, including FATCA, and we shall not be required to pay Additional Amounts with respect to the principal of, interest and any other payments on, the debt securities on account of any such deduction or withholding required pursuant to FATCA.

**Modification and Waiver**

**Debt securities issued under the 2011 Senior Indenture**

Under the terms of the debt securities issued under the 2011 Senior Indenture, we and the trustee may make certain modifications and amendments of the applicable indenture with respect to any series of debt securities without the consent of the holders of the debt securities. Other modifications and amendments may be made to the indenture with the consent of the holder or holders of not less than a majority in aggregate outstanding principal amount of the debt securities of the series outstanding under the indenture that are affected by the modification or amendment, voting as one class. However, no modifications or amendments may be made without the consent of the holder of each debt security affected that would:

(i) change the stated maturity of the principal amount of any debt security;

(ii) reduce the principal amount of, the interest rates, or any premium payable upon the redemption of, or the payments with respect to any debt security;

(iii) change any obligation to pay Additional Amounts;

(iv) change the currency of payment;

(v) impair the right to institute suit for the enforcement of any payment due and payable;

(vi) reduce the percentage in aggregate principal amount of outstanding debt securities of the series necessary to modify or amend the relevant indenture or to waive compliance with certain provisions of the relevant indenture and any past event of default (as such term is defined in the relevant indenture); or

(vii) modify the above requirements or requirements regarding waiver or past defaults.

**Debt securities issued under the 2016 Senior Indenture**

Under the terms of the debt securities issued under the 2016 Senior Indenture, we and the trustee may make certain modifications and amendments to the applicable indenture with respect to each series of debt securities without the consent of the holders of the debt securities, including, to the extent necessary, to give effect to the exercise by the relevant UK resolution authority of the UK bail-in power, including the bail-in consent. Other modifications and amendments may be made to the relevant indenture with the consent of the holder or holders of not less than a majority in aggregate outstanding principal amount of the debt securities of the series outstanding under the relevant indenture that are affected by the modification or amendment, voting as one class. However, no modifications or amendments may be made without the consent of the holder of each debt security affected that would (unless such modification or amendment is a result of the exercise of the UK bail-in power by the relevant UK resolution authority):

(i) change the stated maturity of the principal amount of any debt security;

------

(ii) reduce the principal amount of, the interest rates, or any premium payable upon the redemption of, or the payments with respect to any debt security;

(iii) reduce the amount of principal on any original issue discount security;

(iv) change any obligation to pay Additional Amounts;

(v) change the currency of payment of the principal amount of, premium or interest on any debt security;

(vi) impair the right to institute suit for the enforcement of any payment due and payable;

(vii) reduce the percentage in aggregate principal amount of outstanding debt securities of the series necessary to modify or amend the relevant indenture or to waive compliance with certain provisions of the relevant indenture and any past event of default (as such term is defined in the relevant indenture); or

(viii) modify the above requirements or requirements regarding waiver or past defaults.

**Events of Default**

With respect to the debt securities, each of the following is an "Event of Default":

–Failure to pay any principal or interest on any debt securities of that series within 14 days from the due date for payment and the principal or interest has not been duly paid within a further 14 days following written notice from the trustee or from holders of 25% in outstanding principal amount of the debt securities of that series to us requiring the payment to be made. It shall not, however, be an Event of Default if during the 14 days after the notice, we satisfy the trustee that such sums were not paid in order to comply with a law regulation or order of any court of competent jurisdiction. Where there is doubt as to the validity or applicability of any such law, regulation or order, it shall not be an Event of Default if we act on the advice given to us during the 14 day period by independent legal advisers approved by the trustee; or

–Breach of any covenant or warranty of the relevant indenture (other than as stated above with respect to payments when due) and that breach has not been remedied or waived within 60 days of receipt of a written notice from holders of at least 25% in outstanding principal amount of the debt securities of that series requiring the breach to be remedied; or

–Either a court of competent jurisdiction issues an order which is not successfully appealed within 30 days, or an effective shareholders' resolution is validly adopted, for our winding-up (other than under or in connection with a scheme of reconstruction, merger or amalgamation not involving bankruptcy or insolvency).

If an Event of Default occurs and is continuing, the trustee or the holders of at least 25% in outstanding principal amount of the debt securities of that series may at their discretion declare the debt securities of that series to be due and repayable immediately (and the debt securities of that series shall thereby become due and repayable) at their outstanding principal amount (or at such other repayment amount as may be specified in or determined in accordance with the relevant prospectus supplement) together with accrued interest, if any, as provided in the prospectus supplement. The trustee may at its discretion and without further notice institute such proceedings as it may think suitable, against us to enforce payment. Subject to the indenture provisions for the indemnification of or provision of security to the trustee, the holder(s) of a majority in aggregate principal amount of the outstanding debt securities of any series shall have the right to direct any trust or power conferred on the trustee with respect to the series. However, this direction must not be in conflict with any rule of law or the indenture, and must not be unjustly prejudicial to the holder(s) of any debt securities of that series not taking part in the direction, as determined by the trustee. The trustee may also take any other action, consistent with the direction, that it deems proper.

We are required to furnish to the trustee annually a statement as to our compliance with all conditions and covenants under the indentures.

**Limitation of Remedies**

The holder or holders of not less than a majority in aggregate principal amount of the outstanding debt securities of any series may waive any past default with respect to the series, except a default in respect of the payment of interest, if any, or principal of (or premium, if any) or payments on any debt security or a covenant or provision of the applicable indenture which cannot be modified or amended without the consent of each holder of debt securities of such series. The holders shall provide written notice to the trustee of such waiver.

Subject to the provisions of the relevant indenture relating to the duties of the trustee, if an Event of Default occurs and is continuing with respect to the debt securities of any series, the trustee will be under no obligation to any holder or holders of the debt securities of the series, unless they have offered reasonable indemnity or security satisfactory to the trustee.

The indentures provide that the trustee will, within 90 days after the occurrence of an Event of Default of which a responsible officer of the trustee has written notice with respect to the debt securities of any series known to it, give to each holder of the debt securities of the affected series notice of the Event of Default unless the Event of Default has been cured or waived. However, the trustee shall be protected in withholding notice if it determines in good faith that withholding notice is in the interest of the holders.

In addition, with respect to the debt securities issued under the 2011 Senior Indenture, subject to the indenture provisions for the indemnification of or provision of security to the Bank of New York Mellon, the holder or holders of a majority in aggregate principal amount of the outstanding debt securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Bank of New York Mellon or exercising any trust or power conferred on the Bank of New York Mellon with respect to the series, if the direction is not in conflict with any rule of law or with the indenture and the Bank of New York Mellon does not determine that the action would be unjustly prejudicial to the holder or holders of any debt securities of any series not taking part in that direction. The Bank of New York Mellon may take any other action that it deems proper which is not inconsistent with that direction.

------

**Covenants**

**Debt securities issued under the 2011 Senior Indenture**

Under the terms of the debt securities issued under the 2011 Senior Indenture, the United Kingdom (or any political subdivision thereof or therein having the power to tax) may require us to withhold or deduct amounts from payments of principal or interest on the applicable series of debt securities, for taxes or other governmental charges. If such a withholding or deduction is required, we may be required to pay additional amounts such that the net amount paid to holders of the applicable debt securities, after such deduction or withholding, equals the amount that would have been payable had no such withholding or deduction been required.

All payments in respect of the applicable series of debt securities will be made subject to any withholding or deduction required pursuant to FATCA, and we shall not be required to pay additional amounts with respect to the principal of, interest and any other payments on, the debt securities on account of any such deduction or withholding required pursuant to FATCA.

We can legally release ourselves from any payment or other obligations on the applicable series of debt securities, except for various obligations described below, if such debt securities have become due and payable or will become due and payable at their stated maturity within one year or are to be called for redemption within one year and we deposit in trust for your benefit and the benefit of all other direct holders of such debt securities, a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the applicable series of debt securities on their due date. In addition, on the date of such deposit, we must not be in default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described above under "Events of Default".. A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded. However, even if we take these actions, a number of our obligations under the indenture will remain.

The 2011 Senior Indenture does not contain any covenants or other provisions designed to protect holders of the debt securities against a reduction in our creditworthiness in the event of a highly leveraged transaction or that would prohibit other transactions that might adversely affect holders of the debt securities, including, among other things, through the incurrence of additional indebtedness.

**Debt securities issued under the 2016 Senior Indenture**

Under the terms of the debt securities issued under the 2016 Senior Indenture, the United Kingdom (or any political subdivision thereof or therein having the power to tax) may require us to withhold or deduct amounts from payments of principal or interest on the applicable series of debt securities, for taxes or other governmental charges. If such a withholding or deduction is required, we may be required to pay additional amounts such that the net amount paid to holders of the debt securities, after such deduction or withholding, equals the amount that would have been payable had no such withholding or deduction been required.

All payments in respect of the applicable series of debt securities will be made subject to any withholding or deduction required pursuant to FATCA, and we shall not be required to pay additional amounts with respect to the principal of, interest and any other payments on, the debt securities on account of any such deduction or withholding required pursuant to FATCA.

We can legally release ourselves from any payment or other obligations on the applicable series of debt securities, except for various obligations described below, if, inter alia, either:

all debt securities of such series theretofore authenticated and delivered have been delivered to the trustee for cancellation; or

the debt securities of such series not theretofore delivered to the trustee for cancellation have become due and payable or will become due and payable at their stated maturity within one year or are to be called for redemption within one year or are to be exchanged for stock or other securities and notice of such exchange has been given; and

we deposit in trust with the trustee for your benefit and the benefit of all other direct holders of debt securities, a combination of money or U.S. government obligations (with respect to securities denominated in dollars) or foreign government obligations (with respect to securities denominated in the same foreign currency) that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates. In addition, on the date of such deposit, we must not be in default. For purposes of this no-default test, a default would include an event of default that has occurred and not been cured, as described above under "Events of Default". A default for this purpose would also include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded. However, even if we take these actions, a number of our obligations under the indenture will remain.

The 2016 Senior Indenture does not contain any covenants or other provisions designed to protect holders of the debt securities against a reduction in our creditworthiness in the event of a highly leveraged transaction or that would prohibit other transactions that might adversely affect holders of the debt securities, including, among other things, through the incurrence of additional indebtedness.

**Agreement with Respect to the Exercise of UK Bail-in Power**

**4.000% Notes due 2024:**

The terms of the 4.000% Notes due 2024 provide that, by its acquisition of the applicable series of debt securities, each holder of such debt securities (including each beneficial owner) acknowledges, agrees to be bound by and consents to the exercise of any UK bail-in power by the relevant UK resolution authority that may result in (i) the cancellation, write-down or reduction of all, or a portion, of the principal amount of, or interest on, the notes and/or (ii) any other modification of such debt securities and/or (iii) the conversion of all, or a portion, of the principal amount of, or interest on, such debt securities into our or another person's shares or other securities or other obligations to give effect to the exercise by the relevant UK resolution authority of such UK bail-in power, and the rights of the holders of such debt securities will be subject to the provisions of any UK bail-in power which are expressed to implement such a reduction, write-down, cancellation, modification or conversion. In addition, by its acquisition of applicable series of debt securities, each holder of such debt securities (including each beneficial owner) acknowledges, agrees to be bound by and consents to the exercise of any UK bail-in power by the relevant UK resolution authority in

------

relation to the guarantees of such debt securities. We refer to such agreements and acknowledgements with respect to the exercise of the UK bail-in power as the "bail-in consent."

For purposes of the 4.000% Notes due 2024, a "UK bail-in power" is any statutory power to effect a cancellation, write-down, reduction, modification and/or conversion of a liability existing from time to time under any laws, regulations, rules or requirements relating to the resolution of banks, banking group companies, credit institutions, investment firms and their parent undertakings incorporated in the United Kingdom in effect and applicable to the issuer or any member of the Santander UK Group (as defined herein), including but not limited to the UK Banking Act 2009, as the same may be amended from time to time (whether pursuant to the UK Financial Services (Banking Reform) Act 2013 or otherwise), and any laws, regulations, rules or requirements which are implemented, adopted or enacted within the context of a European Union directive or regulation of the European Parliament and of the EU Council establishing a framework for the recovery and resolution of credit institutions, investment firms and their parent undertakings, pursuant to which liabilities of a bank, banking group company, a credit institution, investment firm, its parent undertaking or any of its affiliates can be cancelled, written down, reduced, modified and/or converted into shares or other securities or obligations of the issuer or any other person (and a reference to the "relevant UK resolution authority" is to any authority with the ability to exercise a UK bail-in power).

No repayment of the principal amount of the applicable series of debt securities or payment of interest on the notes will become due and payable after the exercise of any UK bail-in power by the relevant UK resolution authority unless, at the time that such repayment or payment, respectively, is scheduled to become due, such repayment or payment would be permitted to be made by us after the exercise of such UK bail-in power.

The bail-in consent will be governed by, and construed in accordance with, the laws of England and Wales.

By its acquisition of the applicable series of debt securities, each holder of such debt securities, to the extent permitted by the Trust Indenture Act, waives any and all claims against the trustee for, agrees not to initiate a suit against the trustee in respect of, and agrees that the trustee will not be liable for, any action that the trustee takes, or abstains from taking, in either case in accordance with the exercise of the UK bail-in power by the relevant UK resolution authority with respect to such debt securities.

Upon the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the applicable series of debt securities, we will provide a written notice to DTC as soon as practicable regarding such exercise of the UK bail-in power for purposes of notifying holders of such debt securities of such occurrence. We will also deliver a copy of such notice to the trustee for information purposes.

The exercise of the UK bail-in power by the relevant UK resolution authority with respect to such debt securities and/or the guarantees will not be an Event of Default (as defined in the 2011 Senior Indenture) with respect to such debt securities and/or the related guarantees.

By its acquisition of the applicable series of debt securities, each holder of such debt securities acknowledges and agrees that the exercise of the UK bail-in power by the relevant UK resolution authority with respect to such debt securities and/or the guarantees shall not give rise to an Event of Default for purposes of Section 315(b) (Notice of Default) and Section 315(c) (Duties of the Trustee in Case of Default) of the Trust Indenture Act.

Our obligations to indemnify the trustee in accordance with the 2011 Senior Indenture shall survive the exercise of the UK bail-in power by the relevant UK resolution authority with respect to any debt securities.

By its acquisition of the applicable series of debt securities, each holder of such debt securities acknowledges and agrees that, upon the exercise of any UK bail-in power by the relevant UK resolution authority with respect to such debt securities, (a) the trustee shall not be required to take any further directions from holders of the affected debt securities under the 2011 Senior Indenture, which section authorizes holders of a majority in aggregate outstanding principal amount of the debt securities of a series to direct certain actions relating to the debt securities, and (b) the 2011 Senior Indenture shall impose no duties upon the trustee whatsoever with respect to the exercise of any UK bail-in power by the relevant UK resolution authority. Notwithstanding the foregoing, if, following the completion of the exercise of the UK bail-in power by the relevant UK resolution authority, such debt securities remain outstanding (for example, if the exercise of the UK bail-in power results in only a partial write-down of the principal of the debt securities), then the trustee's duties under the 2011 Senior Indenture shall remain applicable with respect to the notes following such completion to the extent that the issuer, the guarantor and the trustee shall agree pursuant to another supplemental indenture or an amendment to the 2011 Senior Indenture; provided, however, that notwithstanding the exercise of the UK bail-in power by the relevant UK authority, there shall at all times be a trustee for the debt securities in accordance with the 2011 Senior Indenture, and the resignation and/or removal of the trustee and the appointment of a successor trustee will continue to be governed by the 2011 Senior Indenture, including to the extent no additional supplemental indenture or amendment is agreed upon in the event the debt securities remain outstanding following the completion of the exercise of the UK bail-in power.

By its acquisition of the applicable series of debt securities, each holder of such debt securities (a) acknowledges and agrees to be bound by and consents to the exercise of any UK bail-in power as it may be imposed without any prior notice by the relevant UK resolution authority of its decision to exercise such power with respect to such debt securities and (b) shall be deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary through which it holds such notes to take any and all necessary action, if required, to implement the exercise of any UK bail-in power with respect to such debt securities as it may be imposed, without any further action or direction on the part of such holder or the trustee.

**Debt securities issued under the 2016 Senior Indenture**

The debt securities issued under the 2016 Senior Indenture provide that, notwithstanding any other term of such debt securities, the indenture or any other agreements, arrangements, or understandings between us and any holder of debt securities issued under the 2016 Senior Indenture, by its acquisition of such debt securities, each holder of such debt securities (including each holder of a beneficial interest in such debt securities) acknowledges, accepts, agrees to be bound by and consents to: (a) the effect of the exercise of a U.K. bail-in power (as defined below) by the relevant UK resolution authority (as defined below) whether or not imposed with prior notice, that may include and result in any of the following, or some combination thereof: (i) the reduction of all, or a portion, of the Amounts Due (as defined below); (ii) the conversion of all, or a portion, of the Amounts Due on the debt securities issued under the 2016 Senior Indenture into shares, other securities or other obligations of ours or another person (and the issue to or conferral on the holders of such debt securities of such shares, securities or obligations), including by means of an amendment, modification or variation of the terms of such debt securities; (iii) the

------

cancellation of the debt securities issued under the 2016 Senior Indenture; (iv) the amendment or alteration of the maturity of the debt securities issued under the 2016 Senior Indenture or amendment of the amount of interest payable on such debt securities, or the date on which the interest becomes payable, including by suspending payment for a temporary period; and (b) the variation of the terms of such debt securities, if necessary, to give effect to the exercise of the UK bail-in power by the relevant UK resolution authority.

For these purposes, "Amounts Due" are the principal amount of, and accrued but unpaid interest, including any Additional Amounts (as defined above) due on, the debt securities issued under the 2016 Senior Indenture. References to principal and interest will include payments of principal and interest that have become due and payable but which have not been paid, prior to the exercise of any UK bail-in power by the relevant UK resolution authority.

The "UK bail-in power" is any write-down, conversion, transfer, modification, or suspension power existing from time to time under, and exercised in compliance with, any laws, regulations, rules or requirements in effect in the United Kingdom, relating to the transposition of Directive 2014/59/EU establishing a framework for the recovery and resolution of credit institutions and investment firms as amended from time to time ("BRRD"), including but not limited to the UK Banking Act 2009, as the same may be amended form time to time, including by the Financial Services (Banking Reform) Act 2013 (the "Banking Act"), and the instruments, rules and standards created thereunder, pursuant to which: (i) any obligation of a regulated entity (or other affiliate of such regulated entity) can be reduced, cancelled, modified, or converted into shares, other securities, or other obligations of such regulated entity or any other person (or suspended for a temporary period); and (ii) any right in a contract governing an obligation of a regulated entity may be deemed to have been exercised.

We refer to such agreements and acknowledgments with respect to the exercise of the UK bail-in power as the "bail-in consent."

A reference to a "regulated entity" is to any BRRD undertaking as such term is defined under the PRA Rulebook promulgated by the United Kingdom Prudential Regulation Authority, as amended form time to time, which includes, certain credit institutions, investment firms, and certain of their parent or holding companies and a reference to the "relevant UK resolution authority" is to the Bank of England or any other authority with the ability to exercise a UK bail-in power.

No Amounts Due on any series of debt securities issued under the 2016 Senior Indenture, will become due and payable or be paid after the exercise of any UK bail-in power by the relevant UK resolution authority if and to the extent such Amounts Due have been reduced, converted, cancelled, amended or altered as a result of such exercise.

By its acquisition of the debt securities issued under the 2016 Senior Indenture, each holder of the debt securities (including each holder of a beneficial interest in the debt securities), to the extent permitted by the Trust Indenture Act, will waive any and all claims, in law and/or in equity, against the trustee for, agree not to initiate a suit against the trustee in respect of, and agree that the trustee will not be liable for, any action that the trustee takes, or abstains from taking, in either case in accordance with the exercise of the UK bail-in power by the relevant UK resolution authority with respect to such debt securities.

Upon the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the debt securities issued under the 2016 Senior Indenture, we will provide a written notice to the holders of such debt securities through DTC as soon as practicable regarding such exercise of the UK bail-in power. We will also deliver a copy of such notice to the trustee for information purposes.

Neither a reduction or cancellation, in part or in full, of the Amounts Due, the conversion thereof into another security or obligation of us or another person, as a result of the exercise of the UK bail-in power by the relevant UK resolution authority with respect to us, nor the exercise of the UK bail-in power by the relevant UK resolution authority with respect to the debt securities issued under the 2016 Senior Indenture will be an Event of Default with respect to such debt securities.

By its acquisition of the debt securities issued under the 2016 Senior Indenture, each holder of such debt securities (including each holder of a beneficial interest in such debt securities) acknowledges and agrees that neither a cancellation or deemed cancellation of the principal or interest (in each case, in whole or in part), nor the exercise of the UK bail-in power by the relevant UK resolution authority with respect to such debt securities will give rise to an default for purposes of Section 315(b) (Notice of Default) and Section 315(c) (Duties of the Trustee in Case of Default) of the Trust Indenture Act.

By its acquisition of the debt securities issued under the 2016 Senior Indenture, each holder of such debt securities (including each holder of a beneficial interest in such debt securities) acknowledges and agrees that, upon the exercise of the UK bail-in power by the relevant UK resolution authority, (a) the trustee will not be required to take any further directions from the holders of debt securities issued under the 2016 Senior Indenture with respect to any portion of such debt securities that are written-down, converted to equity and/or cancelled under Section 5.12 (Control by Holders) of the 2016 Senior Indenture, and (b) the relevant indenture will not impose any duties upon the trustee whatsoever with respect to the exercise of any UK bail-in power by the relevant UK resolution authority. Notwithstanding the foregoing, if, following the completion of the exercise of the UK bail-in power by the relevant UK resolution authority, the debt securities issued under the 2016 Senior Indenture remain outstanding (for example, if the exercise of the UK bail-in power results in only a partial write-down of the principal of the debt securities), then the trustee's duties under the relevant indenture shall remain applicable with respect to such debt securities following such completion to the extent that we and the trustee shall agree pursuant to another supplemental indenture or an amendment to the relevant indenture; provided, however, that notwithstanding the exercise of the UK bail-in power by the relevant UK authority, so long as any debt securities issued under the 2016 Senior Indenture remain outstanding, there will at all times be a trustee for such debt securities in accordance with the relevant indenture, and the resignation and/or removal of the trustee and the appointment of a successor trustee will continue to be governed by the relevant indenture, including to the extent no additional supplemental indenture or amendment is agreed upon in the event such debt securities remain outstanding following the completion of the exercise of the UK bail-in power.

By its acquisition of the debt securities issued under the 2016 Senior Indenture, each holder of such debt securities (including each holder of a beneficial interest in such debt securities) shall be deemed to have authorized, directed and requested DTC and any direct participant in DTC or other intermediary through which it holds such debt securities to take any and all necessary action, if required, to implement the exercise of any UK bail-in power with respect to such debt securities as it may be imposed, without any further action or direction on the part of such holder or the trustee. In addition, the exercise of the UK bail-in power may require that interests in the debt securities issued under the 2016

------

Senior Indenture be held and/or other actions implementing the UK bail-in power to be taken, as the case may be, through clearing systems, intermediaries or persons other than DTC.

**Consolidation, Merger and Sale of Assets; Assumption**

**Debt securities issued under the 2011 Senior Indenture**

With respect to the debt securities issued under the 2011 Senior Indenture we may, without the consent of the holders of any of the debt securities, consolidate with, merge into or transfer or lease our assets substantially as an entirety to any person, provided that any successor corporation formed by any consolidation or amalgamation, or any transferee or lessee of our assets, is a company organized under the laws of the European Union or the laws of the United States, Canada, Australia or New Zealand that assumes, by a supplemental indenture, our obligations, on the debt securities, on the guarantees and under the indenture, and we procure the delivery of a customary officer's certificate and legal opinion providing that the conditions precedent to the transaction have been complied with.

Subject to applicable law and regulation, Santander UK or any wholly-owned subsidiaries of Santander UK may assume our obligations under the debt securities of any series without the consent of any holder, provided that, if such subsidiary assumes such obligations, Santander UK confirms that its guarantees as guarantor will apply to such subsidiary's obligations under the debt securities of that series. Upon such assumption, all of our direct obligations under the debt securities of the series and the applicable indenture shall immediately be discharged. Any Additional Amounts under the debt securities of the series will be payable in respect of taxes imposed by the jurisdiction in which the assuming entity is incorporated, subject to exceptions equivalent to those that apply to any obligation to pay Additional Amounts in respect of taxes imposed by the taxing jurisdiction of the issuer, rather than taxes imposed by the taxing jurisdiction in which the assuming entity is incorporated. However, if Santander UK makes payment under the guarantee, it shall be required to pay Additional Amounts related to taxes, subject to the exceptions described under the heading "Additional Amounts" above, imposed by any taxing jurisdiction by reason of the guarantee payment. The entity that assumes our obligations will also be entitled to redeem the debt securities of the relevant series in the circumstances described in "Redemption" above with respect to any change or amendment to, or change in the application or official interpretation of, the laws or regulations (including any treaty) of the assuming subsidiary's jurisdiction of incorporation which occurs after the date of the assumption.

**Debt securities issued under the 2016 Senior Indenture**

With respect to the debt securities issued under the 2016 Senior Indenture, we may, without the consent of the holders of any of the debt securities, consolidate or amalgamate with, merge into or transfer or lease our property and assets substantially as an entirety to any person, provided that any successor corporation formed by any consolidation or amalgamation, or any transferee or lessee of our assets, is a company organized under the laws of England and Wales, the laws of any member state of the European Union (as the same may be constituted from time to time), or the laws of any state of the United States, the laws of any province of Canada, the laws of Australia or the laws of New Zealand that assumes, by a supplemental indenture, our obligations on the debt securities and under the indenture, and we procure the delivery of a customary officer's certificate and legal opinion providing that the conditions precedent to the transaction have been complied with.

Subject to applicable law and regulation, a holding company of us or any of our wholly-owned subsidiaries (the "successor entity") may assume our obligations under the debt securities of any series without the consent of any holder; provided, that:

–the successor entity expressly assumes such obligations by an amendment to the indenture, in a form satisfactory to the trustee, and we, by an amendment to the indenture, unconditionally guarantee all of such successor entity's obligations under the debt securities of such series and the relevant indenture, as so modified by such amendment;

–the successor entity confirms in such amendment to the indenture that any Additional Amounts under the debt securities of the series will be payable in respect of taxes imposed by the jurisdiction in which the successor entity is incorporated, subject to exceptions equivalent to those that apply to any obligation to pay Additional Amounts in respect of taxes imposed by the taxing jurisdiction of the issuer, rather than taxes imposed by the taxing jurisdiction in which the successor entity is incorporated; and

– immediately after giving effect to such assumption of obligations, no Event of Default and no event which, after notice or lapse of time or both, would become an Event of Default, with respect to the debt securities of such series shall have occurred and be continuing.

The successor entity that assumes our obligations will also be entitled to redeem the debt securities of the relevant series in the circumstances described in "—Redemption" above with respect to any change or amendment to, or change in the application or official interpretation of, the laws or regulations (including any treaty) of the successor entity's jurisdiction of incorporation which occurs after the date of the assumption

**Satisfaction and Discharge**

The 2011 Senior Indenture and the 2016 Senior Indenture, as applicable, shall upon our written request cease to be of further effect with respect to the applicable debt securities (except as to any surviving rights of registration of transfer or exchange of debt securities of such series expressly provided for), and the trustee, at our expense, shall execute proper instruments acknowledging satisfaction and discharge of the applicable indenture with respect to the debt securities of such series when:

(a) either:

(i) all debt securities of such series theretofore authenticated and delivered (other than (A) debt securities which have been destroyed, lost or stolen and which have been replaced or paid and (B) debt securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by us and thereafter repaid to us or discharged from such trust, have been delivered to us for cancellation; or

(ii) all such debt securities not theretofore delivered to the trustee for cancellation:

(A) have become due and payable or will become due and payable at their stated maturity within one year, or

(B) are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice of redemption by the trustee in the name, and at the expense, of ours, or

------

(C) are to be exchanged for stock or other securities of ours or another entity or other entities and notice of exchange of such debt securities for stock or other securities of ours or another entity or other entities shall have been given,

and we have deposited or caused to be deposited with the trustee, as trust funds in trust for the purpose, an amount in cash, or U.S. government obligations (with respect to debt securities denominated in dollars) or foreign government securities (with respect to debt securities denominated in the same foreign currency) maturing, in the case of (A) and (B) above, as to principal and interest, if any, and, in the case of (C) above, as to accrued interest, if any, in such amounts and at such times as will ensure the availability of cash sufficient to pay and discharge all claims with respect to such debt securities not theretofore delivered to the trustee for cancellation, in the case of (A) and (B) above, for principal (and premium, if any) and accrued interest, if any, and, in the case of (C) above, as to accrued interest, if any, to the date of such deposit (in the case of debt securities which have become due and payable) or to the redemption date;

(b) we have paid or caused to be paid all other sums payable hereunder by us with respect to the debt securities of such series; and

(c) we have delivered to the trustee an officer's certificate and an opinion of counsel, each stating that all conditions precedent provided for relating to the satisfaction and discharge of the applicable indenture with respect to the debt securities of such series have been complied with.

Notwithstanding any satisfaction and discharge of the relevant Indenture with respect to the debt securities of such series, our obligations to the trustee, the obligations of the trustee to any authenticating agent and, if cash, U.S. government obligations and/or foreign government securities shall have been deposited with the trustee, the obligations of the trustee in relation to the application of trust money shall survive such satisfaction and discharge, including any termination under any bankruptcy law.

All cash, U.S. government obligations and foreign government securities deposited with the trustee pursuant to the provisions described in this section shall be held in trust and such cash and the proceeds from such U.S. government obligations and/or foreign government securities shall be applied by it, in accordance with the provisions of the debt securities of such series, and the applicable indenture, to the payment, either directly or through any paying agent (including us acting as paying agent) as the trustee may determine, to the persons entitled thereto, of the principal (and premium, if any) and interest for the payment of which such cash, U.S. government obligations and/or foreign government securities have been deposited with the trustee.

The trustee, the calculation agent and any paying agent promptly shall pay to us upon our written request any excess money, U.S. government obligations and/or foreign government securities held by them at any time with respect to any series of debt securities.

**The Trustee and Paying Agent**

With respect to the debt securities issued under the 2016 Senior Indenture, Citibank, N.A., 388 Greenwich Street, New York, New York 10013 United States, is the trustee and paying agent (as successor to Wells Fargo Bank, National Association pursuant to an agreement of resignation, appointment and acceptance dated April 19, 2021 among us, the trustee and Wells Fargo Bank, National Association).

The debt securities, the 2011 Senior Indenture and the 2016 Senior Indenture are governed by and construed in accordance with the laws of the State of New York, except that the authorization and execution of the 2016 Senior Indenture and the debt securities are governed (in addition to the laws of the State of New York relevant to execution) by the respective jurisdictions of the issuer and the trustee, as the case may be. In respect of Senior Securities, the bail-in power or consent will be governed by, and construed in accordance with, the laws of England and Wales.
