DIRECTORS REPORTCHAIRMANS STATEMENT

Chairmans statement




2009 has been a year of substantial achievement for your company against a most difficult economic backcloth. We took decisive
management action, saw the opportunity for a value-creating transaction, which we successfully completed, and strengthened our balance sheet. Consequently, we are well positioned to build on the strengths of the enlarged CSR and return to growth in
2010. A year ago, my comments focused on the unprecedented economic down-turn, following the global financial crisis and explained
how we were actively taking steps that would position the Group to come through the difficult conditions that 2009 was expected to create. This year, my comments focus on CSRs achievements in 2009 and our ability to leverage these through 2010 and beyond. As we expected, 2009 was indeed a very challenging year. General consumer confidence across the world hit new lows. For us, this was reflected both by decreased levels of demand for consumer electronics and also by substantial
de-stocking by our customers and by their distribution channels, particularly in the first half of the year. Inevitably, demand for our products, and hence our revenue, was directly affected. 2009 revenue was $601.4 million, a fall of $93.5 million,
or 13% down, on the revenue of $694.9 million for 2008. Ignoring the contribution to revenues in the second half of 2009 from the acquisition of SiRF, CSRs revenues on a like for like basis were approximately $471.4 million or 32% lower than
2008. The operating loss for the year was $15.9 million, against a loss of $8.5 million in 2008. Underlying operating profit fell to $26.9 million in 2009 from $72.8 million in 2008. A year ago, I nevertheless expressed the view that our strategy and the prompt actions we had taken in response to the downturn positioned us to work through the difficult times, and that we were
capable


of building on our strengths and would fight to maintain our market leading position. I also expressed confidence in our management team to take the action necessary to achieve these objectives
and in the underlying opportunities for future growth in the wireless connectivity markets. This confidence was well placed. Management
did indeed take the necessary actions, delivering as we had promised on the efficiency programmes we put in place. In addition, the pace of penetration of wireless connectivity and new applications has continued in mobile phones, in consumer
electronics more widely and in other sectors, such as automotive. The Board also recognised that challenging times can create
opportunities. We identified such an opportunity in the acquisition with SiRF, a market leader in location and related technology, and a business we saw as being wholly complementary to our own. We announced the SiRF transaction in February last year and completed it last June. SiRF is now fully integrated into CSR. The new business
contributed approximately $130.0 million in revenue, out of a total of $407.9 million for the second half of 2009. Moreover, SiRF has enlarged our business, brought talented new people into our organisation, expanded our technological capabilities,
our customer base and our position in the Connectivity Centre, delivered synergies in accordance with our expectations and helped increase our cash flows. It has already added shareholder value, and it has helped CSR exit 2009 a stronger company, with greater potential to further add value. We remain appropriately cautious about the global economic outlook for 2010. Who wouldnt? But we believe that our strengths and the dynamics of our market place mean we can look again to
organic growth this year. We also remain alert to possible

further value-creating strategic moves. We have no current specific intentions, but our world is not static, and we believe CSR has the proven ability to take advantage of selective opportunities
and we end 2009 with a markedly strengthened balance sheet with over $400 million net cash and treasury deposits. In preparation for
the SiRF transaction, the management teams worked together on a detailed and robust integration plan which we initiated as soon as the deal was finalised. In addition to giving us a strong presence in Silicon Valley and China, the acquisition
brought a substantial number of new people into the organisation. The combination of two technology companies with the inevitable overlap in skill-sets and roles unfortunately meant that some redundancies in each of the formerly separate
organisations was necessary. The redundancy process was carried out with sensitivity but also promptly, allowing us to re-align the newly enlarged organisation and to focus on the future and the growth of the new business. Product portfolio 2009 saw us make significant progress on developing our product portfolio. We launched our new BC7000 family of
products which comprises our latest generation of Bluetooth with FM transmit and receive functionality. This was positively received. It has reinforced business from existing customers and has led to new demand from others. Other key product launches have included our BT/Wi-Fi module, our standalone Wi-Fi chip and CSR Synergy, our new software stack, which supports the
integration of multiple wireless devices and builds on the successful legacy of our widely adopted BlueCore Host Software. Following
the acquisition of SiRF, we also secured business with SiRFstarIV, our next generation GPS chip and a direct reflection of the collaboration between the newly combined CSR and SiRF teams. As Joep van Beurden, our CEO explores in his review, we expect the sharing of knowledge, ideas and experience within our enlarged technology teams to
result in further significant product announcements


during this year, in projects that advance and go beyond our established strongholds in GPS and Bluetooth. Board changes Following the completion of the SiRF acquisition, we were delighted to welcome Dado Banatao, SiRFs Executive Chairman and Interim CEO, as a Non-Executive Director. Dado brings a broad perspective and extensive experience in our
sector gained from executive and non-executive roles he has held in semiconductor businesses around the world and from his background as an engineer, from which he is credited with developing several key semiconductor technologies. In addition, Kanwar Chadha, a founder and former Vice President of Marketing at SiRF, has joined our Board as an Executive Director and our Chief
Marketing Officer. Well-known and respected throughout our industry, Kanwar was instrumental in the growth and development of SiRF and brings extensive knowledge of the consumer technology landscape. He has over 23 years of experience in various,
technical, marketing and management positions at leading organisations including S3 Inc., AQuesT, Inc., and Intel. As planned, David
Tucker who was chairman of our Audit Committee and our Senior Independent Director, retired in May last year. We thank him very much for his expertise and valuable contribution to the Board over the last five years. Following Davids retirement, Anthony Carlisle, who has been a non-executive director of CSR since July 2005, was appointed the Senior
Independent Director, and Andrew Allner, who joined our Board in October 2008 was appointed Chairman of the Audit Committee. We are delighted to have such strong individuals to assume where David left off. A committed team CSR is a global business serving a global market. Our products are sold to leading electronic consumer brands who in turn sell to customers around the world. Our key designs are created in the UK, US and China, whilst most of our
manufacturing takes place in the Far East. The consumers who rely on our products are located around the world.

What we are today, and what we can become tomorrow, flow directly from the skills, dedication and
attitude of our people. I find it encouraging and energising to see so many different nationalities and skill-sets working together across the full range of disciplines in our organisation and across the geographies in which we operate. Through
their efforts, we are executing well, delivering on our Connectivity Centre and platform strategy and opening-up new areas for growth. I thank them all unreservedly for their resilience, commitment and contribution. 2010 will be another challenging year, but I expect us to continue to build on the progress made in 2009. We have an excellent and growing suite of
products, a well-judged strategy, a strong financial base and a great team. We look forward with confidence. Ron Mackintosh Chairman

DIRECTORS REPORTCHIEF EXECUTIVES REVIEW

Chief Executives review




Despite the considerable macro challenges of 2009, CSR made strong strategic, operational and
commercial progress during the year. This has strengthened our business, delivered significant shareholder value over the year and positioned us for our next phase of growth. In the first half of last year, the management actions we had put in place at the end of 2008 meant we were in a much stronger position to withstand the impacts of the global recession. We also took
the opportunity for a value-creating acquisition of SiRF which we completed at the end of June. We predicted that the first half of
2009 would prove difficult and our results reflected this with revenue down for that period at $193.5 million in 2009 against $349.3 million in 2008. In the second half, largely as a result of the ending of de-stocking in our customer channels, and
the successful integration of SiRF, we were able to increase revenues against the equivalent period in 2008, saw a return to profitability and substantially strengthened our balance sheet. SiRF contributed approximately $130.0 million of revenue in
the second half, resulting in revenues for that period being $407.9 million compared with $345.6 million in 2008. Throughout the year,
we launched an entire new generation of connectivity, audio and location products. Commercially, our design win traction has been excellent. This is illustrated by the fact that we won more Bluetooth design wins in 2009 than all of our competition
put together. 2010 will not be plain sailing for anyone; but the achievements of last year have significantly widened and deepened our
pool of talent, product portfolio and market position. Coupled with our strong financial position, all this equips us to grow and create shareholder value. 2009  a platform for 2010 and beyond Throughout 2009, the company has stayed focused on the Connectivity Centre. The Connectivity Centre brings together many aspects of wireless connectivity products: Bluetooth, FM radio, Wi-Fi, high
quality audio for music, Bluetooth low energy, Near Field Communications and GPS location-finding


technology. All these technologies can ultimately co-exist alongside each other. The acquisition of SiRF has complemented CSRs existing software GPS technology, materially expanded our GPS product offerings and has turned our company into a leader in location technology. Building on our strength in the Connectivity Centre, the combined company has successfully expanded our product portfolio and offer connectivity,
location and audio platforms. CSR and SiRF: natural partners Opportunity is an integral aspect of crisis and when we saw the opportunity to acquire SiRF we moved quickly. Coming as it did at the economic and market nadir, this required courage and commitment from both management
teams, boards and shareholders. With the two companies coming together, it was important that the integration was carried out smoothly
and at speed. I am proud to report that we fully integrated the two entities within three months, and ahead of schedule. As an example of the speed with which we integrated, the new, combined sales force was fully operational within just two days,
keeping any disruption at the customer level to an absolute minimum. The new strengths brought into the enlarged company prompted an
evolution in the way we work with our market places during 2009. We are now organised into three Business Units: Handsets (HBU), Automotive & PNDs (APBU) and Audio and Consumer Electronics (ACBU). HBU accounts for around half of our
revenue, with the balance shared roughly equally across the other two units.

DIRECTORS REPORTCHIEF EXECUTIVES REVIEW continued






A new generation of platforms and products Throughout 2009 we launched an entire new generation of connectivity, audio and location platforms and products, these included:  ·

The BC7000 family, which combines Bluetooth with FM Transmit, FM Receive, Bluetooth low energy and GPS capability. This brand new, high
performance product is now designed-in with multiple Tier One customers.  ·

UniFi6000, our third generation embedded Wi-Fi product, offers the smallest chip size together with low cost. Announced in Q4, we are currently
ramping into mass production with three customers, including with our launch customer (a leading Japanese mobile phone manufacturer), who are all taking UniFi6000 as part of our CSR9000 module. There is also significant interest from other
customers.  ·

CSR9000, our Bluetooth, FM radio and Wi-Fi combination module, is in mass production. In November, we learned that this product had been
certified under Chinas Wireless LAN Authentication and Privacy Infrastructure (WAPI) qualification, making it an ideal option for Chinas many OEMs developing leading wireless technologies for the rapidly growing Chinese market.  ·

The SiRFstarIVe and IVt next generation GPS products both achieved successful launches in the summer, to considerable customer acclaim.
SiRFstarIVe is optimised for consumer electronic devices such as digital cameras, while the SiRFstarIVt is optimised for mobile phones. We are delighted that we started mass production in the fourth quarter of 2009 with SiRFstarIV, following a
design-win with a leading North American smartphone manufacturer.  ·

Also in 2009, prior to the acquisition, SiRF launched two SOC (system on chip) products, SiRFatlasIV and SiRFprima. These SOCs are complete
personal navigation devices on a single piece of silicon, and bring new standards of performance to both the high and the low ends of the PND marketplace.


Seizing the opportunities presented by connectivity, location and audio platforms With this new generation of products in our Connectivity Centre portfolio, we are a well-balanced company in an excellent position to exploit the
opportunities available in 2010. Our research, which is derived from our proprietary information as well as an analysis of data from
research firms, indicates that the total global market for connectivity location and audio platforms in 2008 was around $3.5 billion. Depending on the macroeconomic picture, we expect this market to increase in value by between 15% and 30% per
year and to be worth between $5 billion and $7 billion by 2012. Connectivity, location and audio are some of the few areas in the semi-conductor industry showing this degree of value growth. The growth opportunity mirrors our three Business Units. In handsets, growth is being driven by the market penetration of smart phones and their
Bluetooth, GPS and audio and Wi-Fi capabilities. There is significant momentum behind smart phones. Nokia and RIM and other seasoned performers in this sector are being joined by relative newcomers such as Palm, Dell, Google and HTC to enable more
and more consumers to take the internet with them, wherever they go. We are now seeing similar trends in the automotive sector. Many
vehicles already feature Bluetooth and GPS, and Wi-Fi is the next logical step. Consumer electronics are on a similar journey. A digital camera can sync with a PC via Bluetooth to create a back-up of a photo while using GPS to ascertain location. Operational excellence Our reputation
is built on technical and commercial innovation, supported by a continuous focus on operational excellence for delivering integrated circuits to our customers utilising the strong relationships with our fabrication and test partners. This continued
during 2009, as with the integration of SiRF, we added additional partners to our supply chain. We place significant emphasis on the
working relationships with our suppliers. As a key part of the planning for the acquisition and the execution of our integration plan, our senior executives met with each




CSR plc Annual Report
and Financial Statements 2009

of our suppliers to discuss the acquisition and outline our objectives, to ensure continuity of supply with our customers. Also during 2009, the strength of partnership between CSR and TSMC
enabled significant progress in the development of the 40nm RF CMOS technology for the companys next generation product families. CSR also continued to enhance and expand its capacity for advanced WLCSP technology addressing all segments of
the merged companys wireless product portfolio, which provides us with technological advantage and provides real benefits in reducing our manufacturing costs. And of course we continued our long standing tradition of industry leading customer service. Confidence in the future At CSR we have not only survived a difficult period, but we have strengthened our position in many
ways. As a leading pure-play connectivity company, we have a broad customer base, an extensive product portfolio and a talented team committed to delivering excellent customer service and an enhanced consumer experience. We are a leading player in the market for wireless connectivity and location: a fast growing segment in the semiconductor market. We are not dependent
on a technology inflexion point or for an infant market to show signs of growth. The Connectivity Centre is established as the real value centre: the opportunity is here, and it is here now. This has been a very harsh recession and our industry is certainly not in full recovery mode. As Vice Chairman of the Global Semi-conductor Alliance,
I am aware of the mood of our peers and recognise that there remains work to be done.


We expect the market for connectivity audio and location platforms to increase in value by between
15% and 30% per year. Our strong strategic, operational and commercial progress puts us in an excellent position to make use of this opportunity. For 2010, we naturally have caution about the global economic outlook, but we believe that the market for connectivity audio and location platforms will show significant growth by value this year and, indeed, beyond. Our achievements
of last year have significantly widened and deepened our capacity and capabilities and, coupled with our strong financial position, this positions us to take advantage of the opportunities and build growth and further shareholder value. Outlook The global economy and our marketplace ended 2009 in significantly better health than they started, and this improved tone has continued into 2010. We will maintain caution about the strength of the economic recovery, but we
nevertheless expect demand for our products to continue to grow, with 2010 seeing significantly increased penetration of connectivity, audio and location technologies. Consumer demand for smartphones and other connectivity devices has gathered pace,
and Bluetooth, GPS and Wi-Fi are becoming important features not just in handsets, but in an increasingly wide array of electronic consumer devices and the automotive industry. Our business is performing well. We expect to ramp several of our new product lines in 2010  BC7000, CSR9000 and SiRFstarIV are all ramping in line with our expectations. Our early success
with these new products gives us confidence in our ability to gain market share in a growing market. Joep van Beurden Chief Executive Officer

DIRECTORS REPORTBUSINESS AND FINANCIAL REVIEW

Business and financial review




Introduction CSR is a leading provider of multifunction connectivity, audio and location platforms. CSRs technology portfolio includes:  ·

Bluetooth;  ·

Global Positioning Systems, (GPS);  ·

Frequency Modulated (FM) Radio;  ·

Wireless-Fidelity or Wi-Fi (typically associated with wireless communication standard (IEEE802.11);  ·

Audio;  ·

Near Field Communication (NFC) which is a short range wireless frequency which enables the transfer of data, including larger files and secure
transaction, between devices. Together these technologies enable silicon platforms that incorporate fully integrated
radio, baseband and microcontroller elements to seamlessly access the Connectivity Centre and other platforms for the benefit of consumers. CSRs technologies have been adopted by market leaders into a wide range of mobile consumer devices such as mobile phones, automobile navigation and telematics systems, personal navigation devices (PNDs), wireless headsets,
personal computers (PCs), mobile internet devices, GPS recreational devices, digital cameras, gaming devices, plus a wide range of personal and commercial tracking applications. Strategy Our strategic objective is to be a leading supplier of integrated circuits for wireless connectivity. To achieve this goal, we intend to: Focus on technologies that form key parts of connectivity and other platforms including Bluetooth, GPS, NFC, high quality audio and Wi-Fi. We believe that large opportunities exist for the deployment of short-range wireless products that provide high quality co-existence capable of operating


concurrently without degradation in optimum performance and that Bluetooth, FM radio, GPS location finding technology, Wi-Fi, high quality audio for music, NFC and other to be developed future
wireless technologies can all ultimately co-exist alongside each other. We believe that the market for connectivity, audio and location
products in the medium term will be driven primarily by developments in smart and feature phones. We believe that, with our help, customers can put world-class connectivity in their products at competitive prices and are able to choose, within
reason, what capabilities they need for any particular product to meet end-customer demand. This provides our customers with an important differentiator. Despite the economic slowdown, we believe that these markets have the potential to grow from
around $3.5 billion in 2008 to between $5 billion and $7 billion by 2012. Increase software content in new products. We believe that increased software content can improve the robustness and flexibility of our solutions and helps to distinguish them from competing
offerings. We also believe our software can increase the overall value proposition of our products and assists customers in efficient integration of our solutions into their devices. In addition, we believe software developed by us or by developers using our development tools, increases the likelihood that customers will use our products in future designs. We intend to increase
the emphasis on software in the future in order to increase the software content of our solutions. We aim to continue to develop tools
to allow OEMs and ODMs to develop their own applications software. This, together with our own embedded software, will help enable us and our customers to create highly featured and differentiated products. Extend expertise within our existing capabilities in wireless technologies. We expect to continue the evolution of our expertise in Bluetooth technology to seek differentiated products for different segments of the market. Our customers are presently incorporating our seventh generation of Bluetooth
into new products that went

into mass production in the third quarter of 2009. We intend to continue the development of further generations of our BlueCore integrated circuits to seek additional features and functionality,
reduce size, and lower power consumption. Focus on lowering the cost of integrated circuits. We intend to continue using the industry standard Complementary Metal Oxide Semiconductor technology, or CMOS, manufacturing process to enable us to
supply integrated circuits with small chip size and low cost, and in high volumes. As we improve our designs, manufacturing and testing technology and obtain greater operational efficiencies with increasing commercial deployment of our integrated
circuits, we believe we will be able to continue to reduce the production costs of our integrated circuits. We have, since 2001,
progressively transitioned to smaller geometries or size of the integrated circuits, which is critical to reducing costs for our customers, and maintaining a competitive advantage. In 2008, we developed a range of new products at 90nm
and 65nm form factor. In 2009, CSR increased volume production for both 90nm and 65nm products. In addition, since 2008 we have been engaged with TSMC on the development of 40nm technology for advanced radio frequency/wireless product applications. We have developed advanced new packaging technology to complement our world-leading Wafer Level Chip Scale Package, or WLCSP,
capability. WLCSP enables us to prepare and package a chip at the wafer level instead of the more traditional method, which involves assembling the package after the wafer has been diced into individual chips. We have expanded our assembly manufacturing base by qualifying the Advanced Semiconductor Engineering, or ASE, facility in Shanghai, China for
manufacturing low cost packages. In addition, we have extended our WLCSP capability by transitioning new products from 8 wafers to ASEs new 12 wafer manufacturing line. This provides efficiencies in testing and packaging and
therefore saves on costs. We work closely with our partners when implementing these new products, as the process of adopting


leading-edge technologies brings significant challenges. In conjunction with TSMC and ASE, we work to ensure that the introduction of these changes does not adversely impact either delivery
schedules or product quality. We intend to continue to build on the strong relationships with both TSMC and ASE, ensuring that our customers benefit from an operational capability focused on world-leading quality, delivery and performance. In addition, with the acquisition of SiRF the supply chain sourcing base has expanded to include Samsung, IBM and ST Microelectronics
for wafer manufacturing. Assembly and test supply has also expanded and includes such major suppliers as STATS ChipPAC Limited, Amkor Technology Inc and Siliconware Precision Industries Limited. We are actively working on multiple projects with this
expanded supply team to ensure cost effective manufacturing capability and exceptional quality across all fabrication disciplines. Enhance sales,
marketing and technical support organisations. We are committed to maintaining the high levels of technical support we currently provide
to our customers, as well as pursuing new markets. We believe that this enables customers to efficiently and effectively integrate our solutions into their devices. We provide this application and engineering support to customers at global locations
thereby enabling us to best support our customers. Leverage expertise in next generation wireless markets. We believe that the evolution of existing wireless standards and the introduction of new standards, with differing performance characteristics that
enable new applications, provides a substantial medium term opportunity. Our single chip, radio frequency and software design expertise, combined with our knowledge of the integration of wireless solutions with our customers products, puts us
in a favourable position to pursue such future opportunities as they arise. Our strategy depends on a number of factors, and may be
materially adversely affected by a deterioration in economic conditions, manufacturing or testing problems arising at our independent suppliers, delays

in designing and introducing new products, competitive pressures and other risks. For a discussion of these risks, see Risk Factors. Overview Our revenue was $601.4 million for 2009, a decline of 13.5% compared to 2008 revenue of $694.9 million (2007: $848.6 million) and is generated principally from the sale of our products to original equipment manufacturers, or OEMs,
and original design manufacturers, or ODMs, serving the retail consumer market. Prior to 2009, over 95% of our revenue was derived from the supply of Bluetooth products. Our operating loss for 2009 was $15.9 million compared to a loss of $8.5 million in 2008 (2007: profit of $150.1 million). The underlying operating profit for 2009 decreased to $26.9 million
compared to $72.8 million in 2008 (2007: underlying operating profit of $181.3 million). Underlying operating profit is a non-GAAP measure, an explanation of our use of non-GAAP measures is given on page 15. On 26 June, 2009, we completed the acquisition of SiRF Technology Holdings, Inc., or SiRF, in a share-for-share transaction in which SiRF became
a subsidiary of CSR, satisfied through the issue of 47,658,256 ordinary shares in CSR plc. Based on the share price of our ordinary shares at the time the transaction was announced on 9 February 2009, this represented a total consideration of
approximately $136 million, which, due to increases in our share price, subsequently increased to $281.5 million on the date of the acquisition. Following the acquisition, around $130 million of the Groups revenue during the remainder of 2009 was derived from GPS products, all of which came from SiRF. The performance of the GPS business acquired as a result of the
acquisition in the second half of 2009 was consistent with our expectations at the time of completion. Excluding the contribution to revenues in the second half of 2009 from the acquisition of SiRF, CSRs revenues on a like for like basis were
approximately $471.4 million or 32% lower than 2008. Our financial results for 2009 include SiRF from the date of completion, but SiRFs financial performance is not reflected in our financial results for the period of 2009 prior to the
acquisition or for any of the prior financial years.


Throughout the year we also maintained our investment in product innovation, reinforced our execution
and built upon our strong customer relationships. Innovative research and development, or R&D, has a material impact on our competitive position, the quality of our products and our results. R&D is at the heart of CSRs strength in the
products and solutions that we offer to our customers, underpinning and enabling our ability to compete effectively. A core objective
of CSRs R&D effort is to bring to market innovative integrated circuits and connectivity solutions to replace existing products and technologies that may be nearing the end of their product lifecycle. Product lifecycles vary  in some
cases they can extend to several years, while in others the rate of technological innovation may compress the lifecycle. Product average selling prices generally decline over the product life cycle. CSR invested $169.7 million in R&D in 2009 as compared with $158.1 million in 2008 and $147.5 million in 2007. We believe that this level of
investment is important to ensure that we are able to continue to compete effectively in a rapidly evolving market which requires the advancement of existing technologies and the development of innovative solutions in order to sell our products to
customers. A discussion of the changes in financial performance of the Business Segments starts on page 18. SiRF is a party to several pending lawsuits, which commenced before the acquisition by CSR and which seek both monetary damages and injunctive relief.
The Company is defending these suits vigorously. No provision has been made in the financial statements because it is not possible to make a reliable estimate of the outcome of this litigation. For further information concerning this litigation,
please see page 49 as well as note 27 to the Consolidated Financial Statements on pages 133 and 134. Business Segments Following the acquisition of SiRF in June 2009, we reorganised the business into three business units:
Handsets (HBU); Audio & Consumer (ACBU) which includes headsets, PCs and consumer products; and Automotive & Personal Navigation Devices (APBU). Prior to this, in the 2008 and 2007 fiscal years, we




CSR plc Annual Report
and Financial Statements 2009

operated in two business segments: Cellular, which included handsets and headsets; and Non-Cellular, which included applications beyond the mobile phone, such as PC, automotive and consumer
applications. The comparative financial information has been restated to be comparable for the three new business segments. As stated above segment information for the period prior to the acquisition does not include SiRFs financial results. In 2009, approximately 52% of revenue was generated by the HBU segment, approximately 27% was generated by the ACBU segment and
approximately 21% was derived from the APBU segment. This compared to 50%, 43% and 7% respectively in 2008. Approximately 60% or $78 million of the total revenue in the APBU segment is derived from GPS-related products following the acquisition of
SiRF. HBU segmentDuring 2009, overall revenue in our handset segment declined by 9.7% compared to 2008, mainly as a
result of the continued impact of the loss of a Bluetooth FM programme with one of our largest customers, which we have previously reported. For a detailed explanation on this matter please see page 17. The overall decline in our sales from 2008 to
2009 was partially offset by the inclusion of revenue derived from the sale of SiRF GPS products in the second half of the year following our acquisition of SiRF. In 2009, we launched BC7000, our Bluetooth and FM Receive/Transmit combination chip device. We secured a number of design wins during the year and by the latter part of 2009 this chip was shipping
into three leading Tier One manufacturers in multiple handset programmes. We expect that during 2010, the level of our revenue derived from BC7000 will increase as a result of additional design wins and the sale of new devices using this technology.
This supports our belief that it is possible to mitigate against economic conditions by bringing differentiating technologies to the market and thereby protecting or securing greater market share. During 2009, the HBU segment made good progress in the launch of new products with a number of our latest generation technologies creating strong
interest. Commercial highlights included good performance


from BC6, our standalone Bluetooth offering, which entered volume production in 2008, and which became our best selling product in 2009, overtaking BC4, the largest selling Bluetooth chip of all
time, which was first launched in 2005. CSR was the first company to qualify its solution for the new Bluetooth 4.0 low energy
(BTLE) specification, continuing our history of being the first company to qualify every Bluetooth standard. While the standard has just been ratified, we are working with multiple customers across multiple end user markets on
interesting applications of BTLE and we expect this new standard, which enables a low energy variant of Bluetooth, to become increasingly important as Bluetooth proliferates across more consumer devices. We also achieved design wins with a number of OEMs for our first generation Wi-Fi part, UniFi1050, which delivered modest sales in 2009. We have been
encouraged by customer interest in either our latest generation Wi-Fi product, UniFi6000, our discrete chip-on-board solution, or CSR9000, our combination product with Bluetooth, FM and Wi-Fi technologies. These products are focused on the handset
market and early engagements on potential design wins have been positive. In the final quarter of 2009, we started shipping CSR9000 to a leading Japanese mobile telephone manufacturer in addition to two other customers, and we continue to work with
a number of other Tier One customers with whom we are targeting additional programmes for 2010. In GPS technology, the acquisition of
SiRF brought together the market leading capabilities of the SiRFstar product family with CSRs own GPS know-how. With the integration of our teams, following completion of the acquisition in June, we continued to develop various products in
this area, including the launch in the third quarter of SiRFstarIV. This product features micropower SiRFaware and
SiRFGeoRecov to enhance location sensitivity and navigation performance and enable the device to be fully operational very quickly after being switched on with minimal battery use. Customer interest in SiRFstarIV during the early sampling phase has
been encouraging and this has led to our first design-win with one of the worlds leading smartphone manufacturers in the fourth quarter.

ACBU segmentRevenue in our Audio and Consumer segment fell by 45.5% against 2008 to $163.3 million. Revenue was adversely
impacted during 2009 by the decline in the total headset market of around 50% (analysis based on CSRs considered view of a number of analysts market reports). For a detailed explanation of the factors impacting sales, please refer to
page 17, which discusses revenue performance in 2009. We focused considerable attention on improving our position in the PC market,
recently launching solutions jointly developed with two Taiwan-based vendors, Realtek and Ralink, who are established suppliers of Wi-Fi technology for the PC market. The solutions are part of our strategy to work with other leading technology
companies to offer integrated solutions, combining features with significant differentiation in this competitive arena. Our relationships with Realtek and Ralink are gaining momentum and have already resulted in a design-win with a leading PC
manufacturer. We are in active dialogue with a number of other leading PC manufacturers who have been quick to see the benefits of our integrated solution. Another segment that has been gaining interest with consumers is the tablet market where we
were recently designed into the new ICD Vega touch screen tablet running on the Android platform. Despite the fall in the total headset
market for much of 2009, the high-end headset market experienced increasing demand for advanced high-end technologies that enable OEMs to provide additional features that enhance the consumers experience when listening to speech or
music, and an example of this was in the market for Stereo Bluetooth headsets. Contributing to this demand was Apples updated iPhone Operating System 3.0, which was launched in the first half of the year. This has led to a significant
increase in the number of devices that can now stream stereo audio over Bluetooth and as a result, our customers are increasingly interested in advanced audio distribution profile (or A2DP) stereo Bluetooth streaming. We have the market leading
products in this area, and during the third quarter, we also released the worlds first Bluetooth Software Development Kits (SDKs) that enable headset manufacturers to build Bluetooth accessories that conform to the Made for iPod
standard. Competition in the headset segment is growing, particularly in developing markets such as China,


where price competition in particular is fierce, especially in the low end markets. Despite these challenges, we continued to be the leading global supplier of Bluetooth integrated circuits for
the headset market and we believe that we offer superior technology. We continue to invest in enhanced audio features for higher end headsets, through maintaining our audio centre of excellence in Detroit, where we develop our market leading
Clear Voice Capture or CVC software and collaborations with key audio specialists such as SRS labs. This is borne out by the growing number of headset manufacturers now endorsing Bluetooth as a high-quality audio transmission mechanism. In gaming, where the economic downturn was expected to result in a severe decline in end user demand and possible delays in the launch
of new products to the market, we saw sales hold up better than we had anticipated and also achieved some encouraging design wins. Particularly pleasing was our win from Sony for their latest portable device the PSP Go which featured our BC5120
product. We also won slots in the controllers for a refreshed PS3 Slim during the year. Manufacturers of gaming devices are heavily reliant on the Christmas market and initial indications are that sales for Christmas 2009 were better than expected,
for example in the PS3. The PSP Go is the first portable gaming device to include Bluetooth and we see significant opportunity in this area. Recognising the dominance of the three main gaming manufacturers, we continue to pursue opportunities to
grow our market share with all of them. GPS is becoming increasingly relevant to consumer electronics manufacturers with the increased
proliferation of location based services and we saw strong interest for our latest GPS technologies. For example, SiRFstarIII is being designed into an increasing number of digital cameras and camcorders. APBU segmentIn this segment our revenue grew by 149% against 2008. The increase in revenue was as a result of the acquisition of SiRF.
Of total GPS revenue gained through the acquisition, approximately 60% was in the APBU segment. This year also saw increased adoption of our Bluetooth and GPS into new build cars. In the second half of the year, car manufacturers increased the
volume of new cars largely in response to recycling initiatives by a number

of governments encouraging consumers to replace aged vehicles with new models. In addition, there is a general trend to embed more connectivity and location technologies in new cars. Finally, the
difficult macroeconomic climate led many automotive manufacturers to give away optional extras in an effort to stimulate demand during the year, including inbuilt Bluetooth handsfree kits. These factors resulted in significantly greater than
expected demand for our automotive products. Our ability to support customers by fulfilling the unexpected requirement for higher volumes of our products helped strengthen our reputation in this demanding sector. We continue to work with a wide
range of automotive OEMs and Tier One suppliers which we believe offer opportunities for further growth through 2010. For example, we are engaged with a leading distributor with the aim of selling our latest generation Wi-Fi into the automotive
industry. In 2009, the PND market started on a weak footing following disappointing Christmas 2008 sales. This prompted concerns about
the future of PNDs which proved to be premature. Nevertheless, demand was weakest in Europe with North America also seeing weak or flat demand for PNDs. In contrast, the Far East and the developing world continued to see increased levels of demand
as electronic mapping for navigation is still new to many of these countries. The market continues to remain very competitive, particularly in the so-called white box market in the Far East. However, our business is performing well and a
good demonstration of the benefits of the acquisition is our recent design-win to supply a leading North American electronics manufacturer where we are providing both the GPS (via our System on Chip (SoC) platform SiRFatlas) and also Bluetooth. SiRFprima, our high-end System on Chip (SoC) platform that combines all the necessary electronic circuits and parts for a complete
system and integrates them into a single silicon chip focused on the in-dash automotive market, has also received two design-wins in China that we expect will lead to significant sales during 2010. We have also achieved design wins with SiRFatlasIV,
our entry-level SoC platform for the PND market. Market Overview Our results of operations during 2007-2009 were materially affected by the following trends, several of


which are likely to continue, in addition to factors connected with the economic downturn that impacted the results for 2009 (other than destocking which is largely complete), and which we expect
are likely to affect performance in 2010. These include:  ·

change in the size of the market for short-range wireless voice and data communications and location and location-based services;  ·

general economic conditions, which affect the level of demand from retail consumers for the connectivity, location and audio products which use
our technology;  ·

the impact of intense competition, from third parties, including in respect of product features, pricing strategies and release of new products;  ·

the recognised trend in the semiconductor industry for declining average selling prices;  ·

the tendency for demand in consumer products to be affected by seasonality;  ·

cyclical trends in the semi-conductor industry generally;  ·

restructuring in the semiconductor industry arising from the economic downturn which could affect the availability of sufficient capacity to meet
our demands for integrated circuits; and  ·

fluctuations in currency exchange rates, which can affect CSRs costs in light of the global nature of its business. The market for short-range wireless connectivity products has grown very quickly over the last few years. In 2009,
notwithstanding the economic recession, the market for these products is believed to have grown by around 20% over 2008 from 2.2 billion units to 2.7 billion units. Even allowing for the current economic uncertainties, based on our analysis of third
party market data, we estimate that the market for these solutions may grow from around $3.5 billion in 2008 to between $5 billion and $7 billion by 2012. In handsets, although on a unit basis the market showed a slight decline in 2009, there remain opportunities, particularly in phones which feature multiple connectivity, audio and location based technologies, where growth is
being driven by the market penetration of smart phones with Bluetooth, GPS, audio and Wi-Fi capabilities. There is significant

DIRECTORS REPORTBUSINESS AND FINANCIAL REVIEW continued






momentum behind smart phones, where Nokia and RIM and other established brands in this sector are being joined by relative newcomers such as Palm, Dell, Google and HTC. We are also seeing positive trends in the adoption of wireless connectivity technologies by the automotive sector. Many vehicles already feature
Bluetooth and GPS and we believe that Wi-Fi is a next step. Consumer electronics shows similar trends. A digital camera can use Bluetooth to sync with a PC to create a back-up of a photo, it can use GPS to ascertain its location, and because the
camera knows its location it can use Wi-Fi to access the internet and deliver more information about what the consumer is photographing. As a consequence of the market opportunities in connectivity, audio and location-based services, competition has intensified as existing and new entrants seek to establish and grow market share. This trend of increasing competition
is expected to continue. As the number of companies supplying wireless technology solutions increases, our customers have access to a greater variety of alternative solutions with differing features to those offered by CSR. They are also able to
seek better prices in return for awarding contracts and, similarly, competitors are often prepared to offer lower prices in order to secure new business. Our markets have also been impacted by the global economic downturn, which has particularly
affected the consumer-oriented markets into which our customers sell. Much of the technology which we develop and supply to our
customers is installed into devices which are sold into consumer markets. Demand for consumer products and therefore for our own products is subject to seasonal variation. This in turn


affects our results which typically are stronger in the second and third quarters of a financial year as our customers increase orders in anticipation of demand for their own products. Revenue derived from the supply of integrated circuits featuring our Bluetooth technologies remained the most significant part of our
revenue in 2009. We believe that, whilst the overall Bluetooth market increased by around 10% in unit terms in 2009, total market revenue from Bluetooth fell in 2009 for the first time which is a result of the ongoing trend towards lower prices over
a products lifecycle, combined with the fact that a larger proportion of the overall Bluetooth market was derived from the sale of handsets (which generally have lower average selling prices). The economic downturn that intensified in the
latter part of 2008 and into 2009, together with continuing uncertainties for the near term economic environment, coupled with market competition, also adversely impacted CSRs results of operations in 2008 and 2009. We rely on our suppliers to provide the volumes of integrated circuits sufficient to meet the demands for our products from our customers. The
economic downturn has resulted in measures being taken by a number of foundries who manufacture, assemble and test integrated circuits to restructure their businesses, resulting in a contraction of overall capacity for the supply of integrated
circuits. If we were unable to secure sufficient capacity from our foundries, our ability to meet customer demand could be affected. We work to maintain a strong relationship with our suppliers and the company has benefited from the commitment of a
number of key suppliers who have supported our business. We continue to work closely with our suppliers in order to ensure our business requirements are able to be satisfied.

Non-GAAP measures Some discussions and analyses in this Annual Report include measures which are not defined by generally accepted accounting principles (GAAP) such as
IFRS. We believe this information, along with comparable IFRS measures, is useful to investors. Our management uses these financial measures, along with the most directly comparable IFRS


financial measures, in evaluating our operating performance and value creation. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial
information presented in compliance with IFRS. Non-GAAP financial measures as reported by us may not be comparable with similarly titled amounts reported by other companies.

DIRECTORS REPORTBUSINESS AND FINANCIAL REVIEW continued






In the following sections and elsewhere in this Annual Report we discuss the following non-GAAP
measures:  ·

Underlying research and development expenses which is equivalent to the heading Other research and development expenses
in the table above;  ·

Underlying sales, marketing and administration expenses which is equivalent to the heading Other sales, marketing and
administration expenses in the table above;  ·

Underlying operating profit which represents Gross profit after deduction of underlying research and
development and underlying sales, marketing and administrative expenses;


·

Underlying net profit which represents underlying operating profit, plus investment income, less finance costs and tax, excluding the
tax effects of the adjustments made to underlying operating profit;  ·

Underlying diluted earnings per share which represents underlying net profit divided by the weighted average number of dilutive
shares; and  ·

Free cash flow which represents cash generated by operations, less amounts spent on tangible and intangible fixed assets. For a detailed discussion of the reasons behind this presentation and full reconciliations of each measure to the
most directly comparable IFRS measure, refer to pages 39 to 44.




The following table presents
revenue, cost of sales, gross profit, total research and development expenses, underlying research and development expenses, total sales, marketing and administrative expenses, underlying sales, marketing and administrative expenses, operating
(loss) profit and underlying operating profit, all in absolute terms and as a percentage of revenue, for 2009 and 2008:

Revenue Our revenue in 2009 fell to $601.4 million, representing a 13.5% decrease on
2008 revenue ($694.9 million). SiRFs contribution to revenue since the acquisition on 26 June 2009 reduced the revenue decline by around 18% or approximately $130.0 million. Excluding SiRF GPS revenue, our revenue declined by $223.5 million,
or 32%, in 2009. We believe that over the same period, the Bluetooth market increased by around 10% in terms of total units sold, although our units sold fell by 16%. There were two primary reasons for our declining sales volumes from 2008 to 2009. The first was the loss of market share in handsets, due to the loss of a Bluetooth+FM programme with our BC5 FM chip
at one of our largest customers (this had also been the main reason for the decline in sales in 2008 compared to 2007). The second was the overall decline in the headset market, which we believe fell by around 50% in revenue terms, with our business
impacted to a similar extent. The adverse impact from our loss of the Bluetooth+FM programme was larger in 2009 than in 2008, as the
proportion of Bluetooth+FM programmes at this customer grew compared to the Bluetooth-only programmes which were reaching their end of life. Towards the end of 2009, we commenced shipment of our BC7000 Bluetooth+FM device to this customer.


There was a further revenue impact due to the volume-weighted average selling price declining by 8.4%
year on year. Average selling price for the legacy CSR Bluetooth business declined by 19.8% but this was partially offset by the higher average selling price for SiRF products. In the second half of 2009, as expected, we commenced volume shipments of our BC7000 devices to several major customers of the handset business unit, which had a positive impact on revenue and we
expect further growth in revenue from this product in 2010. The acquisition of SiRF has widened our customer base, and the proportion
of revenue derived from our top ten customers has fallen in part as a result from 67% in 2008 to 54% in 2009 (in the first half of 2009, 70% of revenue was derived from our top ten customers). This increased diversity in our customer base has
significantly reduced our dependency on several key customers. Our largest customer represented 11% of revenue in 2009 compared to 19% in 2008. Our revenue for 2008 fell to $694.9 million compared to 2007 revenue of $848.6 million, an 18.1% decrease. This was principally due to a reduction of 13.8% year on year in the volume-weighted average

DIRECTORS REPORTBUSINESS AND FINANCIAL REVIEW continued






selling price, which reflected a combination of the trend to lower prices over the life-cycle of our products and competitive pressures in the low-cost headset and other markets, coupled with
lower shipment volume, as a result of a sharp decline in demand from customers at the end of 2008. Volumes of product shipped fell by 5% from 2007 to 2008, largely as a consequence of the loss of a BC5 FM device programme already mentioned and the
decline in demand at the end of 2008.


The loss of the Bluetooth+FM programme resulted in the revenue we derived from the largest customer
as a proportion of our total revenue declining from 29% in 2006 to 26% in 2007 and to 19% in 2008. We have, however, maintained our
strong relationship with this customer, (which was not our largest customer in 2009) and, based on the development of our next generation Bluetooth device BC7000, started to regain market share with this customer in the second half of 2009.




Segment analysis
The following table presents CSRs segmental revenue for 2009, 2008 and 2007. Data for 2008 and 2007 have been restated in line with changes introduced during 2009 to our business segments explained below. SiRF revenue is included in this data
only for the portion of 2009 following the acquisition.

|Audio & Consumer Business Unit |  | 163.3     |  | 299.6     |  | (45.5         | ) |  | 382.7     |  | (21.7         | )
|Automotive & PND Business Unit |  | 127.3     |  | 51.1      |  | 149.1         |   |  | 50.7      |  | 0.8           |  
|Total                          |  | 601.4     |  | 694.9     |  | (13.5         | ) |  | 848.6     |  | (18.1         | )



During 2009, following the acquisition of SiRF, we reorganised our business into three business
units, Handsets (HBU), Audio & Consumer (ACBU) and Automotive and PND (APBU). Each business unit has a manager who is part of the senior executive team. Results for each business unit are regularly reviewed in various forums by senior
management, including the CEO and CFO to understand how they have impacted the results of the Group and to assist in the allocation of resources. HBU segmentHandset segment revenue, which represented 52% of our total revenue in 2009, decreased 9.7% compared to 2008. Excluding SiRF GPS revenue, the fall was around 23%. This was mainly due to the loss of
market share arising from a lost Bluetooth+FM programme explained on page 17. These effects were partially offset by the increased
revenue from GPS shipments, in the second half of the year, following the acquisition of SiRF. The GPS derived revenue in this segment represented approximately $52 million out of the total GPS revenue of approximately $130 million following the
acquisition of SiRF.


Our handset segment revenue, which represents around half of our total revenue decreased 17.1% in
2008 compared to 2007. This was mainly due to a decline in revenue from our largest handset customer, as noted above. Our BC6 ROM
device was our largest shipping product in 2009, overtaking BC4 ROM which was the second largest shipping product. BC4 ROM started shipping in volume in 2005 and was our largest selling product in each of 2006, 2007 and 2008. ACBU segmentAudio & Consumer segment revenue, which represented 27% of our total revenue in 2009, decreased 45.5%
compared to 2008, when it represented 43% of total revenue. Headset revenue was adversely impacted during 2009 by a decline in the total headset market of around 50%. This was a combination of the headset supply chain being significantly
oversupplied during the first half of 2009, as a result of the build up of inventory during the second half of 2008 and the global economic downturn. The oversupply was in large part due to over ordering from customers in response to the legislation
adopted in California

which came into effect in the middle of 2008 requiring that drivers only make and receive calls on their mobile phones using hands-free technology. These levels of inventory had largely cleared
by the start of the second half of the year with the result that order levels recovered; better reflecting underlying market demand. The significant loss of PC market share during 2008 continued to have a negative impact on revenue. The acquisition
of SiRF added only a very small amount of revenue to this business unit. ACBU revenue declined 21.7% between 2007 and 2008. This was
mainly due to a decline in revenue from PC customers, where we lost market share due to strong competition. APBU
segmentAutomotive & PND segment revenue, which represented 21% of our total revenue in 2009, increased 149.1% compared to 2008, when it represented just 7% of total revenue. This increase was due to the SiRF GPS revenue
after the acquisition, with Bluetooth revenue performing relatively well and remaining flat against 2008 in a challenging market. Approximately 60% of revenue in the automotive and PND segment for 2009 was derived from GPS based revenue, resulting
from the acquisition of SiRF. APBU revenue increased slightly from $50.7 million in 2007 to $51.1 million in 2008.

revenue, (or $220.1 million), in 2007. In 2009, sales to our second largest customer also contributed nearly 11% of revenue or approximately $63.9 million. In 2008, sales to the second largest customer contributed 11% of revenue (approximately $75.6
million). In 2007, only our largest customer exceeded 10% of revenue in the period. In 2009, revenue from our top five customers represented 43% of total revenue, as compared to 50% in 2008 and 53% in 2007. Gross profitGross profit consists of revenue less cost of sales.

gross profit to revenue remained at 44.6% of revenue, the same as in 2008. In absolute terms, gross profit fell to $268.3 million from $309.8 million in 2008, a decrease of 13.4%. The acquisition of SiRF had a significant favourable impact on gross margins and increased the second half gross margin percentage. We estimate that
SiRFs historical gross margins on a comparable basis to CSR were around 47% for 2008 and 54% in 2007, which are above the levels historically achieved by CSR. Our gross margin in the first half of 2009 was 41.2%, this increased to 46.2% in the
second half of the year due to a significant improvement in the Bluetooth margins achieved and also as a result of the acquisition of SiRF as there are generally higher gross margins on GPS products. The 2009 gross profit is stated after a $5.8 million charge for fair valued inventory acquired in


connection with the acquisition of SiRF; the $5.8 million fair value adjustment had a negative effect of 1% on the gross margin. Our gross margin for 2008 fell to 44.6% from 46.7% in 2007. In absolute terms, gross profit declined to $309.8 million from $396.3 million in 2007, a decrease of 22%. This decline resulted in part
from increased competition and pressure on margins and also from a change in the mix of end market demand towards handset related sales, which generally have lower margins and feature the basic Bluetooth devices, and away from shipments to the
higher margin headset and PC sectors. The effects of this shift were partially offset by reductions in production costs exceeding
selling price reductions, which had a beneficial effect on gross margins. The overall lower level of revenue also impacted gross margins due to certain fixed overheads recorded in cost of sales.




Research and developmentR&D expense consists of total research and development which is further broken down into underlying research and development, share-based payment charges and amortisation of acquired intangible assets. Underlying R&D consists
primarily of staff costs, engineering costs and depreciation. The following table sets forth the primary components of R&D expenses during the 2009 and 2008 fiscal years:

In 2009, R&D costs were $169.7 million, a 7.3% increase from the $158.1 million of R&D
expenditure in 2008. Underlying research and development costs increased to $155.5 million in 2009 from $147.9 million in 2008,
this was mainly due to the increased headcount in the second half of 2009 following the acquisition of SiRF (2009 average headcount: 811, 2008 average headcount: 697), however these increases were partially offset by the savings made in the Q4 2008
restructuring programme which


saved $20 million across all operating expense categories, and the synergy restructuring programme implemented at completion of the acquisition, which aimed to make $35 million of annualised
savings across all operating expense categories within 60 days. These targets were successfully met and delivered ahead of schedule. The remaining increase in R&D expense was mainly due to the acquisition of SiRF: share options that had been issued to SiRF employees before the completion date were rolled over into CSR share

options, leading to a $2.0 million increase in the R&D share-based payment charge in 2009 and amortisation of intangible assets recognised on acquisition contributed a further $2.0 million of
the increase.


We expect to continue to invest in technological innovation, with a focus on technologies that form
key parts of connectivity, location and audio platforms.


The following table sets forth the primary components of R&D expenses during the 2008 and 2007
fiscal years:

In 2008, our R&D costs were $158.1 million, a 7.1% increase from $147.5 million in 2007. The
increase reflected a 4% average increase in the number of R&D personnel in the first three quarters of 2008, which was reversed in the fourth quarter, and a 6% increase in the exchange rate at which we converted our pound sterling costs into
U.S. dollars (2008: $1.98 = £1.00, 2007: $1.86 = £1.00).

DIRECTORS REPORTBUSINESS AND FINANCIAL REVIEW continued






Sales, marketing and administrative costs in 2009 were $114.5 million, representing a 28.5% decrease from $160.2 million in 2008, the
largest change being the impairment of $52.9 million in 2008, which did not recur. The costs of the Q4 2008 restructuring at $14.4 million were slightly higher than the 2009 integration and restructuring programme associated with the acquisition of
SiRF which totalled $12.2 million. The main components of this charge in 2009 were onerous lease charges of $2.2 million, severance costs of $4.3 million and consultancy and legal costs of $4.5 million. Acquisition fees were $10.6 million, which included brokers fees, reporting accountant fees and legal fees associated with the acquisition of
SiRF. These were charged to the income statement in accordance with International Financial Reporting Standard 3 (revised 2008), which CSR early adopted for the 2009 financial reporting period. Under the rules of the previous IFRS3 applied to our
previous acquisitions,


these costs would have been included within the cost of the investment and ultimately within goodwill. There was a charge of $2.0 million for the amortisation of acquired intangible assets in 2009, this was the amortisation of customer relationships and trade names recognised on the acquisition of SiRF. Underlying sales, marketing and administrative expenses were $85.9 million representing a 3.6% decrease compared to 2008 underlying sales, marketing
and administrative expenses of $89.1 million. There was an increase in the cost base as a result of the acquisition of SiRF; however, the impact of this was more than offset by the cost savings as a result of both the Q4 2008 restructuring and the
2009 synergy programme. There was a further decrease as the 2008 expenses include approximately $2.0 million on independent consultants retained in connection with our operational assessment.

Sales, general and administrative costs in 2008 were $160.2 million, representing a 62.5% increase
from $98.7 million in 2007, mainly due to the charges described below. As a result of an operational strategy assessment in May 2008,
we decided to cease ongoing investment in the UbiNetics protocol stack. This had been acquired with the software business of UbiNetics (VPT)


Limited in August 2005. The main reason for the acquisition had been to expand our footprint in the handset for which a protocol stack was considered necessary. As a result of the subsequent
evolution of the market however, we took the view, then also shared by most of the industry, that the integration of Bluetooth and other technologies into the baseband was unlikely to happen in a meaningful sense in the near future. We therefore
focused our resources on our capabilities in the Connectivity

Centre. This resulted in a non-cash impairment charge of $52.9 million, which included the write down of the goodwill relating to the UbiNetics acquisition ($36.9 million) and certain assets
which will not be used in future development activities ($16.0 million). In response to the economic downturn, a cost reduction
programme was implemented in the fourth quarter of 2008, with the aim of reducing ongoing annualised operating expenses by $20 million in 2009. This programme was successfully completed, and savings commenced in the first quarter of 2009, resulting
in a charge of $14.4 million and the removal of costs of approximately $20 million on an annualised basis. During 2007, we reached an
agreement with the Washington Research Foundation (WRF) to settle its patent infringement suit issued against twelve of our customers. We remained of the view that WRFs infringement suit against its Bluetooth chips was without merit.
Notwithstanding this, we believed that an early resolution of the claim was both in our own and in our customers best interests and accordingly, a settlement payment of $15.0 million was made in April 2007. In connection with this settlement,
we obtained an undertaking from WRF not to sue us, our suppliers, customers or end users for the alleged infringement by our products of the patents asserted in the suit. Underlying sales, marketing and administrative expenses were $89.1 million in 2008 representing an 11.5% increase over 2007 underlying sales, marketing and administrative expenses of $79.9 million.
This increase resulted from a combination of a 3% average increase in headcount in the first three quarters of 2008 (before the restructuring exercise) and a 6% increase in the exchange rates that we used to record our sterling-denominated costs.
There was a further increase in exchange losses of $0.9 million, due to translation differences on un-hedged, non-U.S. dollar denominated assets and liabilities, following the volatility on international foreign currency markets. Underlying sales,
marketing and administrative expenses also reflect expenditures of approximately $2 million on independent consultants retained in connection with our operational assessment described above.


Operating ResultThe operating loss for 2009 was $15.9 million compared to a loss of
$8.5 million in 2008. Underlying operating profit for 2009 was $26.9 million compared to an underlying operating profit of $72.8 million in 2008 and the differences consist primarily of the lower revenue and gross profit as underlying operating
expenses were $241.4 million in 2009 compared with $237.0 million in 2008, an increase of 1.9% and represented a smaller part of the decrease in underlying operating profit. The operating margin in 2009, (including the non-underlying operating
expense items noted above) was a loss of 2.6% compared to a loss of 1.2% in 2008. The underlying operating margin for 2009 was 4.5% compared to 10.5% in 2008. The operating loss for 2008 was $8.5 million, compared to a profit of $150.1 million in 2007. Underlying operating profit declined to $72.8 million in 2008 from $181.3 million in 2007. Investment incomeOur investment income primarily represents interest earned on our cash and cash equivalents. During 2009, we had a
monthly average of $336.7 million in cash, cash equivalents and treasury deposits, an increase of 46% from the monthly average in 2008. A major reason for the increase was the cash, cash equivalents and treasury deposits of $111.5 million acquired
through the acquisition of SiRF. Investment income decreased to $1.9 million in 2009 compared to $6.1 million in 2008, as a result of significantly lower UK and US interest rates. Investment income decreased to $6.1 million in 2008 compared to $7.9 million in 2007. During 2008, we had a monthly average cash, cash equivalents and treasury deposits balance of $231.1 million, an
increase of 40% from the monthly average in 2007. However, this increase was offset by the significantly lower UK and US interest rates. Finance costsFinance costs consist of interest expense and similar charges, unwinding of discount on contingent consideration and foreign exchange losses. Our finance costs amounted to $0.2 million in 2009, a 94%
decrease compared to $4.1 million in 2008. This decrease was primarily due to a loss of $2.6 million for 2008 in foreign exchange translations due to the reduction in the GBP:USD exchange rate

DIRECTORS REPORTBUSINESS AND FINANCIAL REVIEW continued






during that year, and in 2009, there was a gain of $1.0 million as the GBP:USD exchange rate increased. Our finance costs amounted to $4.1 million in 2008, a 71% increase compared to $2.4 million in 2007. This increase was primarily due to $2.6 million foreign exchange losses noted above. Tax The tax credit for 2009 was $2.9 million representing an effective tax rate of 20.6%, compared to a charge of $0.5 million in 2008. The effective tax rate for the year of 20.6% was lower than the UK statutory rate of 28% due to the benefits of the
enhanced tax deduction for R&D expenditure and the impact of lower tax rates in various jurisdictions in which our subsidiaries operate, however this was offset by the tax impact of non-deductible expenses, including the acquisition fees of
$10.6 million explained on page 22 and adjustments in respect of prior years. In 2008, when we had a loss before tax of $6.5 million, the tax charge was $0.5 million a sharp decline from $42.8 million in 2007 as a result of our operating loss in
2008. The major items that affected the tax charge were the non-deductible goodwill impairment of $36.9 million related to UbiNetics (VPT) Limited explained on page 22 and the enhanced tax deduction allowed for R&D expenditure. In 2007, when we
had profit before tax of $155.6 million, the tax charge was $42.8 million, reflecting a marginal tax rate on corporate earnings of 27.5%. For 2010 we currently expect our effective tax rate to be approximately 25%, and for accumulated tax losses to offset current tax payable, resulting in minimal cash tax for the year. Net (loss) incomeWe suffered a net loss of $11.3 million in 2009, compared to a net loss of $6.9 million in 2008. This increased net
loss was mainly due to the lower level of revenue and gross profit, along with the acquisition fees of $10.6 million although these effects were offset by the reduction in impairment charges of $52.9 million which occurred in 2008. The remaining
impact was due to increases in operating expenses, due to the cost base acquired with SiRF. Underlying net profit decreased from $64.2 million in 2008 to $30.7 million in 2009 due mainly to the lower revenue and gross profit, underlying operating
expenses were


$241.4 million in 2009 compared with $237.0 million in 2008, an increase of 1.9% and represented a smaller part of the decrease in underlying net profit. We suffered a net loss of $6.9 million in 2008, compared to net income of $112.8 million in 2007. Earnings per shareBasic and diluted loss per share was $0.07 for 2009, compared to basic and diluted loss per share of $0.05 for 2008.
Underlying diluted earnings per share for 2009 was $0.20 per share, a decrease of 59%, compared to $0.49 per share for 2008. The 2009 earnings per share was impacted by the issuance of 47.7 million shares in connection with the acquisition of
SiRF, which increased by 24.9 million the average weighted basic shares outstanding, and therefore had a $0.01 positive impact on the basic and diluted loss per share and a $0.03 negative impact on underlying diluted earnings per share. Financial Position 1 January 2010

Note that under IAS1 (revised) an opening balance sheet position as at 28 December 2007 has been
presented in the financial statements. Commentary on this balance sheet has not been included. Goodwill Goodwill arose on
the acquisitions of SiRF in 2009, CPS and NordNav in 2007 and Clarity and UbiNetics during 2005. Goodwill of $139.6 million was
recognised on the acquisition of SiRF during 2009. Of this, $84.1 million was allocated to the handset segment, $12.8 million was allocated to the audio and consumer segment and $42.7 million was allocated to the automotive and PND segment,
this allocation was performed based on the expected future benefits for these segments. Also during the period, the estimated remaining consideration payable on the NordNav acquisition was adjusted from $17.5 million to $nil in line with current
forecasts of the amount due under the sale and purchase agreement. This adjustment decreased the goodwill allocated to the handset segment. During 2009, a deferred tax asset was recognised for the brought forward losses of NordNav, and CPS totalling
$6.9 million. This adjustment decreased the goodwill allocated to the handset segment. As a result of the decision to terminate
development of the UbiNetics protocol stack in 2008, all goodwill of $36.9 million relating to the UbiNetics acquisition was written off. The remaining balance of $221.5 million represents the goodwill from the SiRF, CPS, NordNav and Clarity
acquisitions. The annual impairment review did not indicate any impairment of the remaining balances. Fixed assets (other
tangible assets and property, plant and equipment) Fixed assets at 1 January 2010 included the net book value of our software licences of $4.3 million (2008: $5.2 million), which support R&D, $3.3 million of ERP development and
licensing costs, shown in assets in the course of construction, $3.2 million of internally developed technology which consists of development kits to enhance our design capabilities at advanced technology nodes, along with $22.5 million of
in-process and developed R&D purchased as part of the acquisitions in 2009 and 2007 (2008: $14.3 million) and $11.6 million of trade names and customer relationships acquired with SiRF.


The value of our in-process and developed R&D increased by $8.2 million. This was due to
$15.5 million acquired with SiRF, less total amortisation for the enlarged group of $7.3 million. The $11.6 million of trade names and customer relationships represents the $13.8 million acquired with SiRF less amortisation of $2.2 million. The majority of the balance of our tangible fixed assets is made up of test equipment and IT equipment, including 18 production testers
which we consign to our subcontractors. During 2009, we commenced work on a new combined ERP system for the enlarged group and by the end of the year we had spent $3.3 million in development and licensing costs. Inventory Inventory at 1 January 2010 stood at $72.3 million, a 9% increase from the level ($66.2 million) at 2 January
2009, which represents 63 inventory days (2008: 76 days) of the previous three months cost of sales. We aim to keep sufficient inventory to meet the often short customer order lead times in this industry. Trade receivables Trade receivables increased to $84.3 million as at 1 January 2010, up from $65.2 million at 2 January 2009.
The increase was due to the significantly higher level of revenue in the fourth quarter of 2009, compared to the fourth quarter of 2008. Days sales outstanding decreased to 40 days (2008: 58 days). The increase in days sales outstanding
in 2008 was due to the non-payment of invoices on the due date by one distributor. This receivable was collected and the issue has not recurred. Liabilities Our total liabilities increased to $129.1 million at 1 January 2010 from $125.0 million at 2 January 2009. Accounts payable increased by $15.0 million, due to the larger cost base acquired with SiRF and increased manufacturing related creditors. Accounts payable was particularly low in 2008 as there was a reduction in production
levels towards the end of 2008 due to the action we took to reduce inventory in line with demand forecasts for early 2009. Accruals
increased by $39.3 million and the major increases were an increase in payroll related accruals

DIRECTORS REPORTBUSINESS AND FINANCIAL REVIEW continued






of $23.5 million and increases in manufacturing related accruals of $14.7 million, for goods received but not invoiced by the supplier. Tax liabilities decreased by $4.4 million, mainly due to the recognition of deferred tax assets mentioned above under Goodwill, which
occurred in the same jurisdictions as the deferred tax liabilities and hence could be offset. These movements were offset by the
decrease in the contingent consideration related to NordNav of $17.5 million, mentioned above, and the significant decrease in the negative fair value of forward foreign exchange contracts in place. The liability decreased by $31.8 million in the
year as expected, as the differential between the forward contract exchange rates and the current exchange rate narrowed. Further information on our hedging is given below. The future liability will depend upon the differential between current
exchange rates and those rates committed as part of our hedging portfolio. We continue to put forward contracts in place for our forecast sterling expenditures 11-15 months in advance. Liquidity and Capital Resources Our primary source of liquidity is our cash flow from operations. At present, we do not rely on third party financing for any operational cash requirements and therefore liquidity risk is not
considered a significant risk. In our opinion, working capital is sufficient for our present requirements. We manage liquidity risk by
maintaining adequate cash reserves and by continuously monitoring forecasted and actual cash flows and matching the maturity of financial assets and liabilities.

Represents the aggregate of interest received, purchase of treasury deposits and treasury deposits acquired with subsidiaries. Cash,
cash equivalents and treasury deposits increased to $412.4 million at 1 January 2010, from $261.9 million at January 2, 2009, an increase of $150.5 million. The difference compared to the outflow of $11.3 million shown in the table above
is due to amounts placed on treasury deposit of $160.8 million of which $45.0 million was acquired through the acquisition of SiRF (the impact of this is contained within Treasury Management in the table above) and a foreign exchange
gain of $1.0 million from retranslation of non-US dollar cash balances. Treasury deposits represent deposits with an initial term of greater than 90 days, which are shown separately from cash and cash equivalents on CSRs consolidated balance
sheet. During 2009, there was a net cash outflow of $11.3 million, as compared with an outflow of $9.8 million in 2008. Operating cash
flow before movements in working capital contributed $29.7 million as compared to $88.1 million in 2008. The reduction in cash was much larger than the decline in the operating loss because the 2008 operating loss was stated after the $52.9 million
non-cash impairment, with movements in working capital resulting in a cash inflow of

$20.6 million as compared to $8.2 million in 2008. The differences were mainly due to timing of purchases from subcontractors in the fourth quarter of each year and receipt of cash from
customers at the 2008 year end where a distributor failed to pay on time. In 2008, there was a net cash outflow of $9.8 million, as
compared with an inflow of $76.3 million in 2007. Operating cash flow before movements in working capital contributed $88.1 million, as compared with $192.5 million in 2007, with movements in working capital resulting in a cash inflow of $8.2
million, as compared with an inflow of $59.9 million in 2007. In 2007, there was a substantial benefit from working capital movements in the year, mainly due to timing of purchases from subcontractors and receipt of cash from customers at the 2007
year end, compared to the 2006 year end. This pattern was not repeated in 2008. Cash, cash equivalents and treasury deposits increased
to $261.9 million at January 2, 2009 from $245.4 million at December 28, 2007, an increase of $16.5 million. The net cash
inflow on acquisitions of subsidiaries of $66.5 million in 2009 represented the $111.5 million of cash, cash equivalents and treasury deposits acquired through the SiRF acquisition, excluding the $45.0 million of treasury deposits with initial
maturities over 90 days and the acquisition fees paid of $10.6 million, which were included in the operating cash flows before movements in working capital. Cash outflows on acquisitions of subsidiaries of $11.7 million during 2008 related to payments of deferred consideration on the NordNav acquisition and the repayment of the loan notes related to the CPS acquisition. Cash
outflows on acquisitions of $82.0 million during 2007 related to payments of approximately $34 million for the CPS acquisition, and approximately $48 million for the NordNav acquisition (which included $8 million of contingent consideration). During 2008, there was a cash outflow of $20.2 million for the purchase of shares in CSR plc by the CSR Employee Benefit Trust, as
compared to $20.0 million in 2007. There were no purchases during 2009.

(27.2
) Our capital expenditure declined by 41.1% from 2008 to 2009. In order to reduce manufacturing costs, and to secure sufficient testing capacity, we purchase production test equipment and consign it to its subcontractors sites in
Taiwan. We own 18 consigned production testers each costing around $1.5 million when purchased. In 2008, we purchased three additional testers, and did not add to these in 2009. In intangible assets, we spent $3.3 million developing a new Group wide ERP system during 2009, which is expected to be placed into service in 2010. We also spent $2.0 million completing a design
kit for advanced technology nodes. In tangible assets, around $3.0 million of the additions related to IS infrastructure upgrades and expansions, to ensure a stable operating base for the development teams. We expect some increases in capital expenditure in 2010 due to ongoing product development programmes. Taxation and Financing Our net tax in 2009 was a cash
inflow of $1.2 million, the majority of which was the receipt of an R&D tax credit in France. This compared to the tax paid of $30.0 million in 2008, and $29.8 million in 2007. We expect cash inflows from taxation in 2010, as it is possible to
carry back the tax loss in the UK to offset against the 2008 tax paid and obtain a refund. The Group corporation tax creditor of $1.3 million is more than offset by the current tax receivable of $5.4 million.

DIRECTORS REPORTBUSINESS AND FINANCIAL REVIEW continued






There was a cash outflow from other financing of $1.2 million, principally due to repayments under
finance leases of $1.2 million, while in 2008 we had an inflow of $1.2 million, which was principally due to the proceeds on issues of shares upon exercise of share options by employees under our various share option plans, as compared to an outflow
of $0.1 million in 2007. Hedge Accounting Substantially all our sales and costs of sale are denominated in US dollars, the functional currency of all the entities within the Group. Approximately 30% of our operating costs are denominated in pounds sterling. In order to reduce the volatility of our earnings due to exchange rate fluctuations, we enter into forward foreign exchange contracts to fix an
exchange rate for our future pounds sterling-denominated expenditures. We commit to forward contracts between 11 and 15 months in advance, according to our treasury policy. These contracts are accounted for as cash flow hedges and will not affect
profit or loss until the period in which the related transaction is recorded or we conclude that it is no longer probable that the hedged transaction will occur. These contracts also form hedges against exchange gains or losses on the related pounds
sterling liabilities. As of 1 January 2010, forward contracts were in place that gave an average GBP:USD exchange rate of 1.56 for
the coming 11 to 15 months. Historically, the average forward contract rate was as follows: 2009: 1.93; 2008: 1.98; and 2007: 1.88. We expect that with the contracts in place as of 1 January 2010, our sterling denominated expenditures will cost
around 19.2% less in U.S. dollar terms in 2010. The fair value asset of the contracts in place as of 1 January 2010 was $2.2
million. $3.5 million of the related expense was deferred in hedging reserves. The difference of $1.3 million has been recorded as an expense in the income statement as the related transactions have been recorded. More detail is included in note 33
to the consolidated financial statements.


Capital Management and Treasury Policy Our policy is to maintain a strong capital base so as to maintain customer, creditor, investor and market confidence as well as to sustain future development of the business. Our main forms of liquid investments in 2009 were bank and money market deposits. We intend to reinvest cash balances in the business either through
higher levels of investment in working capital and fixed assets or through mergers and acquisitions activity, to support our long-term ambitions. Our issued share capital as of 1 January 2010 was 182,187,878 ordinary shares of 0.1 pence each, an increase of 49,297,057 shares from the 132,890,821 ordinary shares issued in 2008, the major change was due to the issue of
47,658,256 as part of the acquisition of SiRF, these shares were exchanged for the total issued share capital of SiRF. As a result of
the funds raised through our initial public offering in March 2004, our subsequent positive operating cash flows and the acquisition of SiRF, which contributed $111.5 million of treasury deposits, cash and cash equivalents in June 2009, we had a
total of $412.4 million of treasury deposits, cash and cash equivalents at 1 January 2010, an increase of 57.5% from the $261.9 million we held at 2 January 2009. Neither CSR nor any of its subsidiaries is subject to any externally imposed capital requirements. We hold our cash and liquid investments in accordance with the counterparty and settlement risk limits of the treasury policy approved by our Board of directors. We maintain a policy in the placement of cash deposits and investments
with counterparties such that at any one time cash is placed with at least three approved financial institutions. No counterparty with a credit rating of less than Aa3 will be approved. We review the internal control environment regularly, through a
rolling plan of internal audits, the results of which are reported to the Audit Committee. Dividend policy We do not intend to pay a dividend for the foreseeable future. We currently intend to retain future earnings to fund the development and growth of our
business.

Any future payment of dividends will be at the discretion of the Board, after taking into account various factors, including our financial condition, operating results, current and anticipated
cash needs and plans for expansion. CSR Employee Benefit Trust (EBT) From time to time, the CSR Employee Benefit Trust purchases CSR ordinary shares in the stock market. The timing of these purchases is subject to compliance with the listing rules of the UK Listing
Authority, agreement between CSR and the Trustee of the Employee Benefit Trust and on prevailing market prices. The shares are intended to be used for satisfying obligations to deliver shares on the exercise by employees of share options under
CSRs share option programmes, thereby reducing dilution and pressure against institutional investor dilution guidelines. During
2009, no purchases were made. During 2008, the Employee Benefit Trust purchased 3,222,813 CSR ordinary shares, as compared to 1,466,767 shares in 2007, for a total cash consideration of $20.2 million, as compared to $20.0 million in 2007. Off-Balance Sheet Arrangements As of 1 January 2010, we did not have any off-balance sheet arrangements. Contractual Obligations and Commitments As of 1 January 2010 our principal
contractual obligations and commitments consisted of amounts payable under finance leases, operating leases, trade and other payables and outstanding purchase obligations. The following table summarises our contractual obligations and commitments as of 1 January 2010:  Total

The table above excludes tax contingencies of $0.9 million because we are unable to make reasonably
reliable estimates of the period of cash settlement associated with these obligations with the respective taxing authorities. Significant Changes There have been no significant changes in the financial or trading position of the Company
since 1 January 2010. Quantitative and Qualitative Disclosures about Market Risk Details of quantitative and qualitative disclosures about Market Risk are given in note 33 to the consolidated financial statements. Key Performance Indicators We use a range of financial and non-financial performance measures, which we refer to as key performance indicators or KPIs reported on a periodic basis, to measure performance over time. During 2009, we have added gross
margin and operating expenses by function as additional financial KPIs; we have added the average cost per employee as a non-financial KPI. No changes have been made to the source of data or calculation methods used in the period. The source of all
data is consistent with published financial and non financial information. To measure growth of the business: Revenuerepresents sales of integrated circuits to customers, sales of services to customers and royalty income from products sold under a
royalty earning licence net of any estimated provisions for credit notes and returns. LOGO

Our revenue in 2009 fell to $601.4 million, representing a 13.5% decrease on 2008 revenue ($694.9
million). SiRFs contribution to revenue since the acquisition on 26 June 2009 reduced the revenue decline by around 18% or approximately $130.0 million. Excluding SiRF GPS revenue, our revenue declined by $223.5 million, or 32%, in 2009. We
believe that over the same period, the Bluetooth market increased by around 10% in terms of total units sold, although our units sold fell by 16%. There were two primary reasons for our declining sales volumes from 2008 to 2009. The first was the loss of market share in handsets, due to the loss of a Bluetooth+FM programme with our BC5 FM chip at one of our largest customers
(this had also been the main reason for the decline in sales in 2008 compared to 2007). The second was the overall decline in the headset market, which we believe fell by around 50% in revenue terms, with our business impacted to a similar extent. The adverse impact from our loss of the Bluetooth+FM programme was larger in 2009 than in 2008, as the proportion of Bluetooth+FM
programmes at this customer grew compared to the Bluetooth-only programmes which were reaching their end of life. Towards the end of 2009, we commenced shipment of our BC7000 Bluetooth+FM device to this customer. Further discussion of revenue is given in the Financial Performance section above.


To measure performance of the business: Gross marginis used as a measure of the profitability of our sales. We aim to maintain our gross margin in the mid 40% range. Maintaining gross
margin involves a combination of production cost management, minimisation of production overheads and maintaining selling prices by introducing new feature-rich devices which can command a premium selling price. LOGO Gross margin in 2009 remained at 44.6%, the same as in 2008. However, gross margin is stated after the charge for
fair valued inventory acquired with SiRF (inventory was valued at selling price less costs to complete), this charge was $5.8m. This fair value adjustment reduced gross margin by 1%. The acquisition of SiRF had a significant favourable impact on gross margin, which increased the second half gross margin percentage. We target gross margin in the mid 40% range and the SiRF
acquisition has enabled us to maintain our gross margin at the mid to upper end of that range, with the first half gross margin of 41.2% increasing to 46.2% in the second half. Further discussion of gross margin is given in the Financial Performance section above. Underlying operating expenses by functionwhich represents total research and development and total sales, marketing and administrative expenses, (both excluding share-based payment charges, amortisation of acquisition related
intangibles, goodwill impairment, acquisition costs, patent settlement costs, deferred

tax adjustments to goodwill and integration and restructuring charges) are used as a measure of the costs of the underlying business. LOGO We monitor these costs as a percentage of revenue, and aim to maintain R&D cost at or around our target of 20%,
and SG&A costs at or around our target of 10%. We have taken action in the past, such as in our 2008 restructuring programme to reduce costs to achieve this target. During 2009, the percentage of operating expenses rose above this level
primarily due to the lower level of revenue (discussed above) and the effects of the economic downturn. The combination of the actions taken to reduce costs after the SiRF acquisition have reduced costs and the benefit of the increase in our GPS
revenue during the second half of the year, are allowing us to continue the move towards our target. Whilst we aim for these operating
targets, we balance that objective with our view of the appropriate level of operating expense to support the current and future success of the business. Therefore in 2009, we did not cut operating expenditure further despite the lower revenue
levels as we believe that the current level of expense will support the growth of the business as economic conditions improve.


Underlying diluted earnings per shareis used as a measure of the interest each current share
and each potentially dilutive share has in the performance of the business. Underlying diluted earnings per share is calculated as underlying earnings (underlying earnings is (loss) profit for the period, add back share-based payment charges,
amortisation of acquisition related intangibles, goodwill impairment, acquisition costs, patent settlement costs and integration and restructuring charges and less any tax impacts of these items, taking account of the deductability or taxability of
these items) divided by the number of current shares and potentially dilutive shares outstanding. LOGO Underlying diluted earnings per share in 2009 was $0.20, a decrease of 59% compared to $0.49 in 2008. The decrease resulted from the reductions in revenue and gross profit, along with the increases in underlying operating expenses, all of which are
described in more detail above under the Financial Performance section. Growth of underlying diluted earnings per share is a key performance condition for a number of share option schemes. Vesting depends upon relative growth of earnings per share,
adjusted for the UK retail price index or RPI against targets set at the time of grant. None of these conditions were met for the current or preceding year, due to the declines in underlying diluted earnings per share.

To measure working capital management: Inventory turnsis used as a measure of the management of inventory levels in the business and represents the number of times inventory turns
over in an annual period based on the last three months cost of sales of that annual period. LOGO Inventory turns increased in 2009 to 5.8 for the period from 4.8 in 2008. The increase meant that 2009 inventory
turns reflected levels generally expected. 2008 turns were lower due to customers notifying us of reductions in orders within the lead-time for production from our suppliers leading to higher than planned inventory balances. Some of the increased
turns in 2009 were also due to changes in our supply chain, as some of the GPS products are purchased as finished goods items, rather than manufactured, which required less investment in working capital.


Days sales outstanding (DSO)is a measure of the number of days that it takes us to collect
cash after a sale has been made. We calculate days sales outstanding by taking the balance of trade receivables outstanding at the end of the annual period, dividing by the revenue for the previous two monthly periods and then multiplying by the
number of days in those monthly periods. LOGO Note: Data is given at year end dates. The decrease in days sales outstanding for 2009 of 40 days against 2008 figure of 58 reflected a return to more normal levels, within the range of 40-45 days. The increase in days sales outstanding in 2008 was due to the
non-payment of invoices on the due date by one distributor.

Free cash flow is used to represent the cash that we are able to generate from our
operations after taking into account cash flows on capital expenditure. We calculate free cash flow as cash generated by operations (as per the cash flow statement on page 44) less expenditure on tangible and intangible assets (not including
those acquired through acquisition) in the 52 week period (as shown on the cash flow statement). LOGO Free cash flow declined to $37.0 million (2008: $73.7 million), mainly as a result of our lower gross profit and
higher operating expenditures. In 2009, there was a substantial benefit from working capital movements of $20.6 million in the year, compared to $8.2 million in 2008, mainly due to timing of purchases from subcontractors and receipt of cash from
customers at the 2009 year end, compared to the 2008 year end. Further analysis of the Companys liquidity and also of capital resources is set out on pages 26 to 29.


Average cost per employee for each 52 week period is used as a non-financial key
performance indicator of the cost of our key resource  people. It is calculated as salary costs, pension costs and social security costs, divided by the monthly average number of employees for the period, with pounds sterling costs converted
to US dollars at the forward contract rate in place for that period. LOGO We manage the average cost of our employees carefully and aim to expand and utilise our resources in the most
efficient way. In the past year we moved part of our software development operation to Bangalore in India, capitalising on the lower staff costs in the region and the rich pool of talent. As part of the SiRF acquisition, we have acquired a
substantial development team in China who are actively contributing to the Groups new products, particularly in the System on Chip (SoC) area. We expect to continue to develop our business in these areas, which not only have a plentiful supply
of talented engineers, but are also located near many of our customers in key growth markets. The annual increase in 2009 for staff
costs was 2.3% and reflects a combination of a change in the mix of employee location, payrises and currency fluctuations. Much of the increase in 2009 was due to the increase in the number of our US based employees through the SiRF acquisition,
which was not fully offset by the increase in staff in China and India.

Headcount as at the end of the 52 week period is used as a non-financial key performance indicator of the resources available in
the business and is monitored closely in relation to productivity and research and development output. LOGO Note: Data is given at year end dates. Headcount has increased from 975 at the end of 2008 to 1,348 at 1 January 2010; an increase of 38%. This was primarily due to the acquisition of SiRF during Q2 2009, bringing an additional 482 employees to the Group. A
restructuring programme was implemented at the end of Q2 2009 as one of the measures taken to achieve the anticipated $35 million of annualised synergies arising from the acquisition. This led to approximately 100 employees leaving the combined
Group. The headcount reductions were implemented following careful consideration of CSRs long-term strategic objectives and shorter term targets for 2009 and 2010. Social Responsibility We recognise the importance of social, environmental and ethical (SEE) matters
and during 2009, continued to work towards compliance with the ABI disclosure guidelines on social responsibility. We believe that our work is part of a continuous improvement to develop standards and working practices that represent tangible
improvements in the way in which we undertake our business and also meets our responsibilities to the wider community and all our stakeholders. This includes the impact through our operations on the environment, on the safety and well being of our
employees, and end users of our products as well as those who contribute to the


process of the development and manufacture of our products through our suppliers, distributors and customers. Following the acquisition of SiRF, we recognise that we need to more effectively
harmonise best practices which presently are carried out by separate parts of the group. This is an ongoing objective for 2010. SEE
matters are considered an integral part of the philosophy of the Company, and the Board and its committees receive reports as part of their routine business on aspects of SEE issues in addition to other reports from those directors responsible for
such matters as may be appropriate from time to time. The Company expects the highest of ethical standards of all its employees and its
policies and procedures support its stated aim of acting with integrity in all aspects of its operations. From the time of his
appointment in June 2008, the Board director responsible for health and safety matters has been Will Gardiner, Chief Financial Officer. Mr Gardiner met on a number of occasions with those who manage the Companys health and safety issues
including the Chair of the Health, Safety and Environmental (HSE) Committee. An annual report is presented to the Board covering health and safety matters, which includes statistics on accidents and incidents, progress against targets from the
previous period and objectives for the next year. In the UK, we have a Health, Safety and Environmental Committee which meets regularly
and is chaired by the Group Facilities Manager, who is also the senior health and safety manager for the Group. Our Health, Safety, and Environmental policies are available to all employees on our intranet site as are the minutes of the HSE
Committee and current HSE initiatives. Current initiatives are explained below. Throughout 2009 we continued to assess the existing
measures around health and safety management at a number of our overseas offices. This entailed a base line assessment of health and safety standards and management at the locations visited, in addition to providing training on basic practices. This
was augmented by guidance on establishing or improving on current local policies by reference to both local law and best practice within the Group. These activities

will be extended throughout 2010 to include the additional offices that form part of the enlarged CSR group, in particular following the acquisition of SiRF. The executive director with responsibility for the Groups Environmental Management System (EMS) is Mr Chris Ladas, Operations Director. The EMS,
which has the support of the Board, has been developed reflecting our existing low eco-footprint, with all employees working in office based environments, whilst recognising that high standards should be established and maintained across all aspects
of our operations. The ongoing management of EMS is overseen by a team incorporating managers responsible for Facilities, Business Management Systems and Quality Assurance. In June 2009, the Companys recertification assessment against both ISO 14001 and OHSAS 18001 was undertaken by Lloyds Register Quality Assurance Limited which is an internationally
recognised independent assessor. No major nonconformities were raised during this visit. Minor nonconformities found during the reviews were either addressed immediately or, in certain instances, a corrective action plan has been implemented.
Progress in carrying out the action plans is monitored by the Companys internal Quality Assurance department. The assessments confirmed that the Companys Management System continues to satisfy the requirements of ISO 14001:2004 and BS
OHSAS 18001:2007, and continued certification to these standards was awarded. Certification requires that we have an Environmental
Management System (EMS) which defines the environmental policy of the Group and sets objectives intended to drive continuous improvements in environmental awareness and practices. Our environmental policy includes commitments to:  ·

employee consultation and training;  ·

assessment of our activities and product related environmental impacts to identify targets for continuous improvement; and  ·

legal compliance and due consideration of other stakeholder environmental requirements.


We believe that we are taking considerable steps to contribute to sound environmental practices,
covering not only the manufacture and supply of our products but also positive measures to establish and build on good working practices within our various office locations. We continue to prepare for the introduction in the UK of the Carbon Reduction Commitment (or CRC) which begins in 2010. The CRC is a new mandatory Energy Efficiency Scheme in the UK that
aims to reduce energy consumption and contribute to a reduction in carbon dioxide (CO2) emissions. This objective is being managed through financial levies on businesses in the UK based on the consumption of electricity. The CRC applies to organisations that meet certain criteria relating to their consumption of electricity derived from units purchased in 2008. Based
on the qualifying criteria, we must participate in the CRC scheme. Organisations that participate will have to monitor their energy use
and either show reductions against prescribed targets or purchase allowances for each tonne of CO2, based on energy consumed. There are also annual registration fees to pay beginning in 2010 and until the scheme ends, with 2010 being the first data
reporting and registration year. Allowances will be sold by the UK Government in each compliance year through the initial CRC phase from 2011 to 2013. This is intended to provide a direct incentive for businesses to reduce energy use emissions,
since the lower the emissions, the lower the levy paid to the Government. A performance league table will also be published showing the comparative performance of all organisations in reducing emissions, reflecting the annual returns from UK
businesses. We have developed plans and investigated appropriate measures in readiness for the implementation of the CRC scheme. As part of the Carbon Reduction Commitment in the UK, we continued our energy monitoring programme that encompasses taking readings of
our electrical distribution boards to identify potential areas where energy efficiencies can be made. This has highlighted a number of systems where potential savings are

possible and during 2009 we focused our attention on air conditioning and building management systems by adjusting operating times to give optimal utilization. Looking forward into 2010, we are developing purchasing strategies in order that an evaluation of the energy efficiency of a particular item of
equipment is part of the selection criteria. This has already featured in decisions taken on the replacement of the main chillers at our Cambridge site, which constitutes one of our largest offices globally. This is an example of a practice which we
could adopt across all our operations. We remain committed to finding ways in which we can develop further the recycling of spent
materials. During 2008 we met our target of reducing by 40% of total waste produced, the amount of material being consigned to landfill
in the UK. In 2009 we extended our recycling waste streams to include the recycling of plastics and cans, and bio-waste and set a stretching target of recycling 50% of all the waste we produced in the UK which was successfully met. In conjunction
with a local waste contractor our bio waste is processed into compost which can then be made available to local farmers and members of the public as a soil conditioner. The total amount of waste being recycled during 2009 rose from 895,940 litres to
1,130,300 litres. Over the same period, we experienced a 6.7% increase in the amount of waste produced from 2,234,000 litres to 2,384,120. The main objective for 2009 was to tackle our waste at source by finding ways in which we can prevent potential waste from coming on to site in the first place. This has proved very challenging since we have established
through the review that a significant proportion of the waste we consign is unsolicited or unnecessary multiple copies of paper based materials provided by third parties. During 2010 we will be looking at ways in which we can limit the amount of
this material being provided to us, whilst still maintaining the existing challenging recycling target. We will also target increasing our recycling of waste materials from 50% in 2009 to 55% in 2010. During 2009 we continued to utilise Information Technology to support existing energy efficiencies whilst still providing state of the art research
facilities


and data storage capacity. Since 2007, we have successfully reduced power consumption in the UK as a result of improvements to the way in which we store and configure our information systems,
resulting in the equivalent of around 220 fewer physical servers. This is equivalent to a reduction in power consumption against figures as at the end of 2006 of 37%, providing both financial and environmental benefits. In recognition of the increasing globalisation of our business operations, in 2008 we reported on our intention to adopt video conferencing, which was
expected to provide further financial benefits, operating efficiencies and reduction in our carbon footprint. Our target at the start of 2009, was to reduce travel expenditure by 25%. From 1 May 2009, we implemented a programme of rolling out
video and audio conferencing facilities across all our international locations to improve operational efficiencies, and with the aim of reducing our overseas travel. Given the nature of the business activities undertaken by the Company in the
integration process with SiRF, these facilities provided a significant tool with which to conduct meetings thereby limiting the increase in overseas travel. The acquisition however did mean that our original target for reducing travel was not met.
Nevertheless, these facilities have been used for an average of approximately 190 hours every month since its introduction and we envisage utilisation of this facility to increase through 2010. Our objective over the coming year is to further
enhance the video conferencing solution by extending the capabilities to external parties. This next step will allow the company to communicate with customers, partners and suppliers more effectively while at the same time reduce the need to travel. An ongoing objective is to optimise the use of greener materials in our end products. We are committed to developing and
supplying products which meet the highest standards as regards minimising the use of hazardous substances. CSRs products are manufactured and packaged in a variety of forms. Most of these products are already manufactured according to
CSRs own green standards. The green standards have been developed by CSR as part of continual engagement with leading global companies who are customers of CSR and also with the support of our suppliers. CSRs green standards
therefore reflect not only internationally recognised guidelines but also the feedback of our

customers, whose requirements frequently exceed the minimum conditions set by governments and regulators. 2009 has seen the integration of CSR and SiRF into one company. Both companies had
existing programmes for development of green products. Since the acquisition a single green standard has been agreed and all new products developed have met this standardised requirement. As part of our commitment to ensure compliance to international requirements, during the early part of 2010, we will perform a review of the
green standards promulgated by national and supranational agencies, particularly to review developments from the Japan Green Procurement Survey Standardisation Initiative (JGPSSI) and in the USA, the Joint Industry Group (JIG). It is
expected that our green standard will be upgraded to cover both these requirements following this review. We have dedicated
internal resource which assists in the development of all new products and the review of existing product lines targeting the use of greener materials. Part of their role is to monitor established and pending legislation and standards published by
national and supranational governments and agencies and to ensure that we are proactive in going beyond the minimum requirements in our compliance with the types and quantities of materials used. In this respect we work closely with both customers and suppliers in developing products which reduce the use of hazardous materials, and through
testing and certification ensures ongoing compliance. Our standard integrated circuits are fully compliant with all existing European
legislation, including RoHS and REACH, as well as in other territories where equivalent legislation has been introduced. In addition to
procedures that establish and monitor compliance, we have processes in place to make sure that customers are supported with up to date materials information and laboratory analysis to validate the environmental compliance of our products. We recognise the importance of ensuring that our key suppliers have appropriate policies and practices on SEE matters. Key
manufacturing partners are selected and assessed based on certification to appropriate globally recognised standards such as ISO 14001, OHSAS 18001 and SA 8000. Audits of their


operations are undertaken regularly to ensure that appropriate standards and certification exists. During 2009, a review of product environmental compliance was conducted by our Supplier Audit Team at TSMC and ASE in Taiwan. This confirmed that current certifications to the recognised standards mentioned above were being
maintained. The review also considered the suppliers wider HSE policies and management systems in connection with our requirements. The results of these assessments were reported to our management, which concluded that the suppliers complied with
our requirements. Based on the extent of our ongoing engagement with health, safety and environmental matters the Board is satisfied
that there are no significant risks affecting its strategic objectives or the long or short term value of the Group. Employees As of 2 January 2009, we had 975 employees. As a result of the acquisition of SiRF on 26 June 2009, 482 SiRF employees joined the CSR plc
Group. As a result of the restructuring programme that commenced at the end of Q2 2009, approximately 100 employees left CSR. At 1 January 2010, we had 1,348 employees, of which 961 were allocated to R&D, 258 to sales and marketing and 129
to general and administrative. The following tables provides a breakdown of the numbers of employees by functional area and region as of the last three financial year ends:  Functional area

We recognise that a key development for all employees in 2009 was the work in connection with the integration of CSR and SiRF following
the acquisition in June 2009. Bringing together the two workforces was a key driver in achieving the synergies offered by the acquisition, and the organisation as a whole had a significant role to play in the successful accomplishment of this work. Immediately following the acquisition of SiRF, we implemented plans to restructure the organisation. These were carried out following
careful consideration of the strategic objectives and the targeted synergies which had been identified as part of the rationale for the acquisition. This analysis was undertaken in conjunction with operational management to ensure that core projects
remained adequately resourced. We believe it was particularly important that all employees received timely information and were kept up-dated on developments as it affected them. Careful attention was given to implementing changes fairly and
consistently across all countries in which we operate. This included encouraging regular feedback from employees through line management and each of the HR offices in the various locations during the course of implementing significant changes. We recognise that in a business where technical excellence, strong self motivation and creative thinking are key to remaining a world
leader and building future success, our employees play a critical part in enabling the fulfilment of our objectives and delivering long term growth. The challenging economic environment experienced in 2009 did not alter the importance which we
attach to creating a high performance working environment, which allows our employees to reach their full potential in a highly technical and innovative arena. We actively review and encourage the personal development of our employees and have
implemented performance processes to ensure that adequate focus is given to retain and inspire employees to deliver innovative solutions for our customers. We remain committed to providing our employees with a workplace that not only encourages
excellence in their performance but also engenders well being and personal satisfaction. We invest in training and career progression
to support employees in their career development, which we believe also benefits our customers in the quality of service and enables us to remain a world leading


provider of wireless connectivity solutions. The Company promotes and supports individuals and teams through both on-the-job and formal training and works to encourage the development of
knowledge sharing networks. To develop attractive and competitive remuneration packages, we regularly review and benchmark our salary and benefits against companies in our sector and have developed incentives that are aligned to our business delivery and
commercial goals, recognising that we operate in a global market. In the period immediately after June 2009, the Company implemented a
detailed review of benefits provisions in all countries where SiRF and CSR have employees, carefully comparing the prevailing benefits structures for the two companies as well as market practice in each territory to develop harmonised benefits that
offer a compelling reward structure to current and potential employees in what is recognised as a highly competitive market. Some of the key changes introduced as a result of this review were 401(k) matching for the SiRF team in the US, and an
enhancement of local benefits for the team in China, in response to a changing reward landscape in this rapidly evolving market. The feedback from employees to these changes has been largely positive. We recognise our responsibilities to ensure fair treatment of all employees in accordance with national legislation in the territories in which we
operate. Equal opportunities for appropriate training, career development and promotion are available to all employees, regardless of any physical disability, gender, religion, race or nationality. In particular, having regard to their aptitudes and
abilities, we give full and fair consideration to applications for employment received from disabled persons. Provisions for pensions are available for all employees either through participation in the state pension schemes operated by the country
in which the employee is resident or provision of a defined contribution pension scheme. Such defined contribution schemes are maintained in accordance with legislative requirements, custom and practice and Group policy as appropriate. In October 2009, having completed the integration work, we issued our second employee engagement

survey. The survey had an extremely high response rate of 83%, which CSR believes demonstrates the genuine commitment amongst the Companys employees. In a year which saw significant change
for employees, results from the survey showed positive feedback on the way change was planned and communicated, and a continued sense of satisfaction in working for the Group. There were no significant differences in engagement between the legacy
CSR and SiRF teams which also supported the general feedback that the integration had been implemented effectively. The results from the survey have been shared with all employees and a series of focus groups are now working on addressing specific
areas identified from these results. As explained above, one area of positive feedback has been on employee communication and this
reflects further developments over the past 12 months. The global e-newsletter, Rhythm, continues to provide information for employees globally and we believe it offers a key means of communication about developments across the
organisation. Readership has continued to increase with some articles accessed by as many as 850 or over 60% of employees. The contribution to Rhythm spans all levels of the organisation and addresses wide ranging topics that support business and
social networks within our growing Group. Our intranet has also undergone significant change in 2009. Combined with the use of
workspaces and specialist user tools, the intranet also features local and global news as well as departmental content and discussion forums which have proven to aide employee engagement and the sharing of helpful news and information. During 2009, two global meetings were broadcast live from the Cambridge Corn Exchange and in real time to each of the Companys
international locations. Presentations are given on key developments in the business with the opportunity for questions from each office. CSR believes that this forum is an important part of enabling the exchange of views and ideas as well as
providing its employees with a clear understanding of strategy. Our employees are not covered by any collective bargaining arrangements


Reconciliation of non-GAAP measures to IFRS measures In the following sections we set out our definitions of the following non-GAAP measures and provide reconciliations to relevant IFRS measures:  ·

underlying operating profit;  ·

underlying net profit;  ·

underlying research and development expenses;  ·

underlying sales, marketing and administrative expenses;  ·

underlying diluted earnings per share; and  ·

free cash flow. Underlying operating profit, underlying net profit, underlying research and development expenses, underlying sales, marketing and administrative expenses and underlying diluted earnings per share are non-GAAP measures. We comment on
these in detail here because they are the way in which we measure our business internally, they form the basis for managements performance targets, resource allocation decisions and we use them to determine and manage the long term growth of
the business. We present and discuss these measures in order to:  ·

provide consistency with the way management view the business and discuss performance with investors;  ·

ensure that the measures are fully understood in the light of how CSR manages the business;  ·

comply with UK Company Law which requires the presentation of the Groups Key Performance Indicators;  ·

properly define the metrics used and confirm their calculation;  ·

share the metrics with all investors at the same time;

·

disclose the main drivers of management remuneration;  ·

improve transparency for investors;  ·

assist investors in their assessment of the long-term value of CSR; and  ·

therefore assist investors in understanding management behaviour. Beginning on page 41 we provide a reconciliation of each measure to the nearest IFRS measure: underlying operating profit to IFRS operating profit,
underlying net profit to IFRS net (loss) profit, underlying operating expenses to IFRS operating expenses, underlying diluted earnings per share to diluted earnings per share and free cash flow to cash generated by operations. In each of the underlying measures we add back the amortisation and impairment of acquired intangible assets, including goodwill. Our revenue is
driven by the performance of our technology and our customer relationships, some of which is internally generated and some of which has been acquired. The acquired technologies and customer relationships are assigned a finite life and result in an
amortisation charge being recorded in arriving at operating profit. There are no similar charges associated with our internally generated technology and other intangible assets. In addition, from time to time, the Group may be required to recognise
impairments of intangibles and goodwill. No similar charges can occur from our organically grown businesses. We believe that excluding acquisition intangible amortisation and goodwill impairment from our measures of operating performance allows the
operating performance of the businesses that were organically grown and those that have resulted from acquisitions to be analysed on a more comparable basis. From time to time events occur which due to their size or nature are considered separately when discussing the trading performance of the Group. The gains and losses on these discrete items can have a material impact on the
absolute amount of, and trend in, the operating profit and results for the year. Therefore any gains and losses on such items are analysed outside the underlying results to enable the trends in the underlying performance of the business to be


understood. Where items are excluded from the underlying results we provide additional information on these items to enable a full understanding of the events and their financial impact. Examples
of such items are acquisition related fees incurred in 2009 in connection with the SiRF acquisition, deferred tax adjustments to goodwill and the patent dispute settlement in 2007. In each of the underlying measures we add back share option charges. We believe share option charges reflects a non-cash cost which may obscure the trends in the underlying business and these
charges are based on a number of assumptions linked to our share price, the volatility of our share price, the expected performance of our share price compared to a number of other comparator companies and assumptions around employee behaviour.
Therefore management of the segments are not held accountable for the impact of this item on their results of operations. Further,
management believes that due to these subjective assumptions involved in determining the fair value of equity awards and the varying methodologies used to determine equity based compensation across various companies, excluding these amounts from
underlying operating profit and underlying net (loss) profit enhances comparisons of the underlying operating performance of the business with other similar companies. Therefore any charges from these share-based payments are analysed outside the
underlying results to enable the trends in the underlying performance of the business to be understood. Caution CSR cautions that, whilst we have defined underlying operating profit, underlying net profit, underlying operating expenses, underlying diluted
earnings per share and free cash flow, they are not defined terms under IFRS or other GAAP and therefore these definitions should be carefully reviewed and understood by investors. Investors should be aware that their application may vary in
practice from other similarly titled measures presented by other companies and therefore these measures may not be fully comparable between companies. In particular:  ·

Underlying measures of operating expenses and diluted earnings per share are not intended to be a substitute for, or superior to, IFRS measures
in the financial statements;

·

The usefulness of free cash flow as an indicator of investment value is limited, as such measures are based on historical information.  ·

The adjusted items are in some cases recurring or could be expected to recur in the future, and we do not represent that these are in any way
extraordinary or outside the normal course of business.


·

Some of the items that have been adjusted or excluded from non-GAAP performance measures presented in this Annual Report, such as integration or
restructuring charges, are based on managements judgment, in terms of both classification and estimation.

Underlying diluted earnings per share

Underlying diluted earnings per share is calculated as underlying net profit as shown
above divided by the weighted average number of dilutive shares as shown below.

The table below gives a reconciliation of diluted
shares to the diluted shares used in calculating earnings per share as presented on the consolidated income statement on page 93 for the three years presented in the income statement. The numbers differ for 2008 and 2009 as in the loss per share
calculation presented for those periods, share options are not dilutive, however they are dilutive for underlying dilutive earnings per share as underlying earnings represented a profit in both these years. There is no difference in the number of
dilutive shares for 2004, 2005 and 2006.

Free cash flow

Free cash flow is calculated as cash generated by operations (as per the consolidated cash flow statement on page 96) less expenditure on tangible and
intangible assets (not including those acquired through acquisition) in the 52 week period (as shown on the cash flow statement).

The
table below gives a reconciliation of free cash flow to the heading cash generated by operations as presented on the consolidated cash flow statement on page 96 for the three years presented in the cash flow statement. The
calculations for 2004, 2005 and 2006 which are utilised in the Key Performance Indicator section for calculation of free cash flow are performed on a consistent basis.

DIRECTORS REPORTRISK FACTORS

Risk factors




This section describes the principal known risks and uncertainties that could have a material adverse effect on our business, financial
condition, prospects, liquidity or results of operations. The factors discussed below should not be regarded as a complete and comprehensive statement of all potential risks and uncertainties that we face. Additional risks and uncertainties of which
we are not aware or which we currently believe are immaterial may also adversely affect our business, financial condition, prospects, liquidity or results of operations. For information on our risk management policies and procedures, see
 Corporate Governance  Internal control  Managing Risks. Risks
related to the company Our fabless business model, which relies on third party foundries and subcontractors for the manufacture, assembly and testing of
our integrated circuit products, exposes us to risks. We do not own or operate a fabrication facility. We use third party foundries and
subcontractors to manufacture, assemble and test all of our products. We are therefore reliant on these third parties to provide the required capacity to manufacture, assemble and test all of our products and to provide high quality products on
time. We rely in particular on Taiwan Semiconductor Manufacturing Company and Advanced Semiconductor Engineering, both of Taiwan, which undertake a significant proportion of the total subcontracted work on our behalf. Because we are wholly reliant on these third parties, and in particular on TSMC and ASE, we are subject to risks, including:  ·

interruptions in manufacturing or testing at supplier sites, resulting for example from earthquake, pandemic, natural disaster or geopolitical
instability, shortage of materials or failures in their own suppliers;  ·

disruption in supply, changes in working practices affecting product qualification or product quality, changes in management personnel affecting
working relationships, availability of manufacturing capacity or adverse changes to pricing, that may occur within our


suppliers, including potentially as a result of reorganisations, mergers, acquisitions or disposals affecting our suppliers;  ·

the risk that our key suppliers experience financial troubles or become insolvent;  ·

quality problems in our suppliers manufacturing sites, resulting in lower yields, product failures and product returns;  ·

inadequate manufacturing capacity, if our key suppliers commit their manufacturing resources to others, experience plant shut-downs or closures,
or are unable or unwilling to expand capacity or upgrade manufacturing capabilities to meet market demand; and  ·

limited control over delivery schedules, quality assurance and control and production costs. Because we have no long term supply contracts, our suppliers are generally not obligated to perform services or supply products to us for any specific
period, in any specific quantities, or at any specific price, except as may be provided in a particular purchase order. In the event we cannot source products we need from one of our third party suppliers, due for example to a business interruption
event, we may be unable quickly to source our requirements from alternative suppliers. Any of these developments would adversely affect our ability to deliver products, undermine our perceived reliability, and harm our financial condition and
results of operations. The average selling prices of our products are likely to decrease rapidly. The average selling prices of our products have historically declined significantly over their life, and this is likely to continue. We regularly
reduce the average selling prices of our products in response to competitive pricing pressures, new product introductions by us or our competitors and other factors. In 2009, we experienced significant downward pressure on prices for a number of
mature products, and we expect to have to reduce prices on all of our products as they mature. The global recession has caused a significant downturn in the

semiconductor industry, resulting in our competitors becoming more aggressive in their pricing practices, behaviour which we expect to continue in the foreseeable future. Our financial results
could be materially adversely affected if we fail to offset reduced prices by increasing our sales volumes, reducing our costs, or successfully introducing new products at higher prices. Despite the measures taken in 2008 and 2009 to reduce our
costs as part of restructuring measures, we still saw a decline in our operating profit in each of 2008 and 2009. The length of our product design
cycle exposes us to risks. The design and sales cycle for our integrated circuits can take up to 36 months, and in exceptional cases
even longer, and achieving volume production of products using our integrated circuits can take an additional six months or more. This lengthy design cycle makes it difficult to forecast product demand and the timing of orders, and exposes us to the
risk that orders will not ultimately materialize in accordance with our expectations. Even if we have a design win, it may never result in volume shipments. In addition, the delays inherent in lengthy design cycles increase the risk that our
customers may seek to cancel or modify orders. We may suffer delays or experience problems in the introduction of new products. Our products are complex and may contain undetected hardware and software errors or failures when first introduced or as new versions are tested. The
resolution of these errors could cause us to invest significant capital and other resources and divert technical staff from other development efforts. If the introduction of products is delayed, our ability to compete and maintain market share may
be materially adversely affected. If we deliver products with errors, defects or bugs, or that are susceptible to connectivity viruses, our credibility and the market acceptance and sales of our products could be materially adversely affected. We are subject to risks associated with the transition to smaller geometry process technologies. To remain competitive, we expect to continue to transition our semiconductor products to increasingly smaller line width geometries. This transition
requires modifications to the manufacturing processes and the


re-design of some products as well as standard cells and other integrated circuit designs that may be used in multiple products. This may result in reduced manufacturing yields, delays in product
deliveries and increased expenses, all of which could materially adversely impact our results of operations. We may fail to develop new products and
revenue sources or fail to secure new orders with our new technologies. Our future success is dependent upon our ability to develop new
semiconductor solutions for existing and new markets, introduce those products in a cost-effective and timely manner, and convince leading equipment manufacturers to select those products for design into their own new products. Our success also
depends on the development of these markets and adoption of the technologies by our customers. We cannot predict the adoption of these technologies or the growth rate, if any. If we are not able to develop and introduce new products successfully and
in a cost effective and timely manner, our business, prospects, financial condition and results of operations will be materially adversely affected. We
may fail on an accurate and timely basis to anticipate technological and market trends. We are subject to the risk that we may
incorrectly assess trends in technological evolution, industry standards and/or market requirements. This could cause us to invest our R&D monies in the wrong areas, develop products that fail to meet our customers needs, or fail to pursue
product development opportunities that our competitors seize. Technological and market trends are difficult to predict. If we are unable to predict market requirements, end customer demand for product features and evolving industry standards, our
prospects and results of operations could be materially adversely affected. The integration of multiple wireless technologies coexisting with one
another on a single chip may take longer than expected and customer demand for these combination chips may be slow to develop or may not develop at all. The integration of multiple technologies on a single chip which we are developing is a complex process which may take longer to achieve than foreseen and may not achieve the expected level of performance. It is also possible that the
demand from customers for




CSR plc Annual Report
and Financial Statements 2009

---






wireless connectivity solutions incorporating such multiple technologies in a single die is slower to develop than anticipated or fails to develop at all. This could have a material adverse
effect on our business and financial condition. Errors or defects in our products could result in claims from customers. Integrated circuits are highly complex products, and the integrated circuits that we supply to our customers are required to operate to very precise
specifications. We may not detect errors in the research and development of a product or in its manufacture before it is supplied to customers or installed in the customers own finished devices. Any such errors could result in the
customers devices being faulty, which would result in returns from consumers. If the devices failure were attributable to us, we may face claims for losses or damages, costs for rectifying the defects or replacing the product, and loss
of revenue if customers cancel orders. In some cases we have agreements with customers that provide warranty protection or indemnities. Some of these agreements have no limitations on liability, and where there are limitations they may not be
enforceable. Our insurance coverage against losses that might arise as a result of some product defects may not be sufficient to cover claims that are asserted against us, and may not continue to be available on reasonable terms in the future.
Product defects could also have longer-term harmful effects on our reputation or our relationships with our customers. Any of the foregoing could have a material adverse impact on our business, financial condition and results of operations, which in
turn could impact our share price. We rely on a few large customers for a significant portion of our revenue. We work with a broad range of customers across our product portfolio but a few large customers represent a material portion of our total revenue. Our
largest customer accounted for approximately 11% of our net revenue in 2009 and 19% in 2008. Our top five customers accounted for 43% of our net revenue in 2009 and 50% in 2008. If we fail to maintain a good relationship with our key customers, fail
to meet the customers product needs on a timely basis, lose design wins for our products with our key customers, or if any key customer were to reduce or change its orders to us, seek alternate suppliers, increase its


product returns or become unable or fail to meet its payment obligations to us, our revenue could decline materially and our operating results could be materially adversely affected. If any key
customer were to merge or be acquired, this could jeopardise our customer- supplier relationship, particularly if it merges with or is acquired by one of our competitors. If any of our key customers have financial or other difficulties such as an
interruption to their own operations that affects their ability to maintain their business for example a sudden disruption caused by fire, flood, earthquake or other event, this could result in a decline in its orders to us and thus adversely affect
our business and financial performance. We depend on a sole supplier for some critical components. We purchase critical components from a single supplier for certain products. The loss of such supplier, disruption of the supply chain, or delays or
changes in the design cycle time could result in delays in the manufacture and shipment of products, additional expense associated with obtaining a new supplier, impaired margins, reduced production volumes, strained customer relations and loss of
business or could otherwise materially adversely affect our business and results of operations. We rely on Information Technology and automated systems
to conduct our business We rely on Information Technology (or IT) and automated systems to support our operations globally.
A failure or interruption to these systems could materially and adversely affect our business and operations and as a result our financial performance. Our IT systems are a key part of our day to day business, the loss or disruption of which could
affect many aspects of our business, from the development of products, to the ordering and delivery of products, to the accurate recording of financial information. The loss of IT systems could affect our development work, for example by delaying a
project, causing errors to occur in the software we develop for our products, or could mean that we are unable to launch new products on time. In addition, loss of our systems could disrupt or cause delays in recording and satisfying customer
orders, or result in errors in ordering of products from our suppliers. We could also lose the means to make decisions on the conduct of our business on a timely basis which could affect business or investment decisions. If our IT systems fail to
evolve in conjunction with the needs of

DIRECTORS REPORTRISK FACTORS continued






our business, for example because of lack of investment or failure to predict future business needs, our ability to develop new products, maintain adequate operating system or grow our business
could be adversely affected. Any of these events could result in loss of business, additional costs, or inaccurate recording of key business and financial information, which could materially adversely affect our business and results of operations. International economic, political and other risks may harm our results of operations. We derive nearly all of our revenue from sales outside of the U.K. Because we conduct business internationally, we are subject to economic, political and other risks in each of the countries in
which we operate, and our customers are subject to these risks in the countries in which they operate. Such risks include ensuring compliance with multiple sets of laws and regulations, which can change often and may be in conflict, relating to the
import and export of our and our customers products, employment, taxes, and other laws and regulations that apply in our industry; complying with local business practices and managing cultural differences; working with local infrastructure and
transportation networks; and designing products to comply with local regulatory requirements. If we or our customers fail, or are unable, to manage these risks in the various markets in which we operate, our results of operations may be materially
adversely affected. We may in the future require debt or equity financing, which may not be available on reasonable terms or at all. We may, in the future, need to raise additional funds to grow our business. While conditions in the debt and equity capital markets have improved
during 2009, we may be unable to raise additional funds, on reasonable terms, through public or private securities issuances, bank borrowing or other means. Any future share issuances may be dilutive to shareholders, and debt financing, if
available, may subject us to restrictive covenants. Our failure to raise capital, if needed, on reasonable terms could have a material adverse effect on our financial condition. We may be subject to claims that we infringe third party intellectual property rights. We have in the
past been, and currently are, subject to patent infringement litigation. We may be subject to


further intellectual property claims by third parties alleging infringements of their patents or other intellectual property rights. Companies in the semiconductor industry often aggressively
protect and pursue their intellectual property rights. Other parties, including companies that assemble a portfolio of patents and use it to derive substantial licensing revenues, may assert intellectual property infringement claims against our
products. Intellectual property claims could adversely affect our ability to market our products, require the re-design of our products or require us to seek licenses from third parties, and seriously harm both our reputation and operating results.
The defence of such claims and any adverse settlement could result in significant costs and divert the attention of our management or other key employees. As we diversify into different wireless technologies, we may become more susceptible to these
types of infringement claims. Any of the foregoing could have a material adverse impact on our business, operating expenses, financial condition and results of operations. SiRF became a member of the CSR Group and a subsidiary of CSR plc on 26 June 2009. The outcome of any litigation is uncertain and either favourable or unfavourable outcomes could have a material
impact. If infringement claims are brought against the CSR Group, these assertions could distract CSRs management and necessitate the expenditure by the Group of potentially significant funds and resources to defend or settle such claims. No
assurance can be made that third parties, including Broadcom, will not seek to commence additional litigation against the CSR Group including requesting formal enforcement action against SiRF and/or the CSR Group, or that the pending and/or
additional litigation will not have a material adverse effect on the CSR Groups business. The CSR Group cannot be certain that it
will have the financial resources to defend itself against any patent or other intellectual property litigation. If the CSR Group is unsuccessful in any challenge to its rights to market and sell its products, the CSR Group may, among other things,
be required to:  ·

pay actual damages, royalties, lost profits and/or increased damages and the third partys attorneys fees, which may be substantial;

expend significant resources to modify or redesign its products, manufacturing processes or other technology so that it does not infringe
others intellectual property rights or to develop or acquire non-infringing technology, which may not be possible; or  ·

obtain licenses to the disputed rights, which could require the payment of substantial upfront fees and future royalty payments and may not be
available to it on acceptable terms, if at all, or to cease marketing the challenged products. Before the CSR Group could be successful in defending an infringement claim, the CSR Groups customers may already be reluctant to include the CSR
Group on their future product design. Therefore, even if the CSR Group is successful in defending an infringement action, negative publicity could already have a material adverse effect on its business in addition to the expense, time delay, and
burden on management of the litigation itself. The U.S. International Trade Commission, or ITC, has determined that certain products
of SiRF and its customers infringe patents held by Broadcom Corporation, or Broadcom. Although SiRF has obtained approval from U.S. Customs for the importation of products at issue containing new versions of its software, if Broadcom is successful
in obtaining a judgment for substantial monetary damages or granting an injunction against SiRF in relation to SiRFs alleged infringement, our customer relationships may be harmed, and our business, revenue, expenses, financial position and
results of operations could be materially adversely affected. SiRF and four of its customers are subject to a limited exclusion order
and cease and desist orders issued by the ITC, which prohibit the unlicensed entry and sale into the United States of certain products of SiRF and its customers that the ITC has determined infringe six patents held by Broadcom. In August 2008, the
ITC concluded that all six of the asserted Broadcom patents were valid and were infringed by certain of SiRFs products.


Pursuant to a letter dated 21 May 2009 and received by SiRF on 29 May 2009, U.S. Customs issued a
determination involving the redesigned software incorporated into the GPS devices subject to the limited exclusion order issued by the ITC in the ITC proceeding, that SiRF had established by a preponderance of the evidence that SiRFs
redesigned GPS chips fall outside of the scope of the exclusion order issued by the ITC. Broadcom asked the ITC to commence an informal enforcement proceeding against SiRF and two of its customers alleging violations of the cease and desist orders,
which SiRF opposed, and which request was denied by the ITC. Irrespective of the determination by U.S. Customs, there is a risk that the ITC may commence formal enforcement proceedings if Broadcom made such a request. Our business could be
materially and adversely affected by such ITC proceedings including, for example, if the redesigned software is found to be infringing. We are also involved in two patent infringement suits with Broadcom in the United States District Court for the Central District of California. We have denied Broadcoms claimed allegations against us in both suits. One of these
suits seeks monetary damages for and injunctive relief from the alleged infringement of four patents, two of which are at issue in the ITC proceeding. The other suit seeks similar relief in relation to three other Broadcom patents. In this suit,
scheduled for trial in November of this year, Broadcom added allegations against us for False Advertising and Unfair Competition and we have asserted allegations against Broadcom for False Advertising and Unfair Competition. There is a risk that in
one or both of these suits we could be ordered to pay substantial damages to Broadcom for alleged past infringement, enjoined from further allegedly infringing activities including with respect to certain products, and/or required to pay royalties
for any alleged future infringement at a level determined by the court. Furthermore, no assurance can be made that Broadcom will not
seek to commence additional litigation against us, including SiRF, or that the pending or additional litigation with Broadcom will not have a material adverse effect on our business, customer relationships, expenses or results of operations.

Our intellectual property indemnification practices may adversely impact our business. We have agreed to indemnify some customers for costs and damages of intellectual property infringement in some circumstances, which may subject us to
significant indemnification claims by our customers or others. We may also have to defend related third-party infringement claims made directly against us. In some instances, our products are designed for use in devices used by potentially millions
of consumers, such as cellular telephones, and our server software is placed on servers providing wireless network services to end-users, both of which could subject it to considerable exposure should an infringement claim occur. One of our major
customers advised us that it had received notice from one of our competitors that the incorporation of our chip sets into products requires the payment of patent license fees to the competitor. If this competitor or another competitor pursued such
claims, our business could be materially adversely affected We may fail or be unable to obtain sufficient patent protection, which could harm our
competitive position and increase our expenses. Protecting of our proprietary technology is an important part of being able to compete
successfully. Our patent applications may not provide sufficient protection for all competitive aspects of our technology or may not result in issued patents. Issued patents may not provide competitive advantages to us. The laws of some foreign
countries, such as China, in which we operate and/or from which we derive significant amounts of revenue, do not protect intellectual property to the same extent as, for example, the laws of the United States and western Europe. Our competitors may
independently develop similar technologies or design around our patents and could also successfully challenge any issued patent. Even where we have an issued patent, we may choose not to pursue all instances of patent infringement. Our failure or
inability to obtain sufficient patent protection could harm our competitive position and increase our expenses if we are required to pay license fees under patents issued to others.


Our acquisition of SiRF Technology and/or future mergers or acquisitions may not achieve anticipated commercial,
technological or financial benefits, including synergies, and could divert managements attention, cause ownership dilution to our shareholders, and adversely affect our results of operations and share price. From time to time, we have made, and may wish in the future to make acquisitions and engage in mergers and other strategic transactions that are
intended to support our business and commercial objectives, growth and diversification. These strategic transactions may fail to achieve the desired objectives, including for example cost savings, revenue enhancements or technology advancements that
we hope to derive. In particular, our ability to successfully realise cost synergies and revenue enhancements and the timing of this realisation may be adversely affected by a variety of factors, including but not limited to:  ·

our broad geographic areas of operations and the resulting potential complexity of integrating the separate business operations we acquire with
our culture and strategies on a timely basis or at all;  ·

the risk that key employees in acquired businesses may leave, for instance because they are insufficiently incentivised to remain, do not
integrate well with our management culture, or are enticed away by competitors;  ·

difficulties in retaining or developing the customer relationships of the acquired company;  ·

the difficulty of implementing cost savings plans;  ·

the difficulty in identifying and managing liabilities associated with any business we acquire;  ·

the technical challenges associated with combining the technologies of the acquired company with our own technologies; and  ·

unforeseeable events, including major changes in the industries and markets in which we and the acquired company operate.

The success of any strategic transactions will depend on, among other things, our ability to identify
suitable acquisition targets and to finance the transaction. Consideration of strategic opportunities could divert managements attention from our business and the financing of acquisitions may negatively impact our financial condition and
could require us to seek funding from the capital markets, or result in substantial dilution to shareholders. These and other factors
may cause a material adverse effect on our business, prospects, results of operations and financial condition. Loss of key employees could hurt our
competitive position. Our success depends to a significant extent upon our key senior executives and R&D, engineering, marketing,
sales, support and other personnel and our ability to continue to attract, retain and motivate qualified personnel. The loss of the services of any of these key personnel without adequate replacement or the inability to attract new qualified
personnel could have a material adverse effect on us. We may encounter difficulties or incur unexpected costs in complying with the Sarbanes-Oxley Act. To comply with Section 404 of the Sarbanes-Oxley Act and related SEC rules, CSR and its independent registered public accounting
firm will be required to assess the effectiveness of our internal control over financial reporting in each of our future annual reports on Form 20-F, and to identify any material weaknesses. In connection with this process we may need to make
changes to our financial and managerial controls, which may result in substantial expenses and compliance costs. If our management is unable to implement enhancements on a timely basis to our internal controls that are determined to be necessary to
address material weaknesses, (if any), we could be subject to enhanced regulatory scrutiny and a loss of investor confidence, which could lead to a decline in the trading price of our ordinary shares.


Risks related to the industry Depressed economic conditions may continue to adversely affect our financial performance. Our products are predominantly supplied for adoption into devices intended for the consumer market. If depressed economic conditions persist or worsen, demand levels for our customers
products, and therefore for our products, are likely to be materially adversely affected. We expect that a substantial portion of our revenue will continue to be derived from the sale of our technologies to the consumer electronics market and
therefore, to the extent that sales of such consumer devices decline, our revenue and our results of operations and financial condition could be materially adversely affected. Any difficulties experienced by customers and suppliers in accessing
sources of liquidity could seriously disrupt their businesses, which could lead to a significant reduction in their future orders of our products or the inability or failure on their part to meet their payment obligations to us. Our quarterly and therefore annual revenue and operating results are affected by a wide variety of factors, making them difficult to predict and, if we do not meet
quarterly and therefore annual financial expectations, our share price will likely decline. Our quarterly and therefore annual revenue
and operating results are affected by a wide variety of factors, making them difficult to predict. Our results have in the past fluctuated significantly from quarter to quarter, a trend we would expect to continue. Our operating results in some
quarters or annual periods may be materially below market expectations, which would cause the market price of our shares to decline. Our quarterly or annual periods operating results may fluctuate as a result of the risks discussed in this section
and other factors, including:  ·

global economic conditions;  ·

the cyclical nature of the semiconductor industry,  ·

inventory management;  ·

technological changes;  ·

performance of our key customers in the markets they serve;

DIRECTORS REPORTRISK FACTORS continued






·

delays in the introduction of new products;  ·

changes in the relative volume of sales of our chip sets, our premium software offerings and our IP cores or other products and product mix,
which have significantly different average selling prices and gross margins;  ·

unpredictable volume, timing and cancellation of customer orders;  ·

the availability, pricing and timeliness of delivery of components used in our customers products;  ·

changes in foreign exchange rates;  ·

the timing of new product announcements or introductions by us or by our competitors;  ·

design losses to our competitors  ·

the introduction or delay in launch of the our customers products that use our technology;  ·

a decision by one of our customers to terminate use of our technology;  ·

seasonality in our various target markets;  ·

difficulties in managing our product transitions effectively;  ·

intangible asset write-downs; and  ·

developments in litigation proceedings involving the company, including fluctuations in litigation expenses. We base our planned operating expenses in part on our expectations of future revenue, and our expenses are relatively fixed in the short term. If
revenue for a particular period is lower than we expect, we may be unable to reduce our operating expenses proportionately for that period, which would harm our operating results.


We are subject to foreign currency exchange risks. Substantially all of our sales and cost of sales are denominated in US dollars, which is the functional currency of all the entities within the Group. A significant portion of our operating costs
and taxation is denominated in pounds sterling. Although we put in place forward exchange contracts 11 to 15 months in advance to fix the exchange rate of the US dollar to pound sterling for the majority of these costs, movements in the
US dollar to pound sterling rate impact any pound sterling operating costs not covered by the forward contracts and, in the longer term, movements in the rate of exchange will impact all of our sterling costs, as it will affect the rate fixed
by the forward contracts being put in place for future expenditures. We are also exposed to foreign exchange risks from costs recorded in other currencies, which are currently not covered by forward contracts. A material appreciation of the value of
the US dollar against pound sterling could have a material adverse effect on our current year results of operations, mainly due to revaluation losses on sterling-denominated assets, as the forward contracts mentioned above provide a hedge to
movements in most sterling-denominated liabilities. A material depreciation of the value of the US dollar against pound sterling could have a material adverse effect on our future results of operations, due to the recording of pound sterling
operating expense at a higher US dollar exchange rate. Our business is highly cyclical, subject to rapid change and evolving industry standards, and
has experienced significant downturns, including in connection with the recent global financial crisis. We operate in the global
semiconductor industry, which is highly cyclical, subject to rapid change and evolving industry standards and has experienced significant downturns, often in connection with maturing products and declines in general economic conditions, including in
connection with the recent global financial crisis. Such downturns have reflected decreases in product demand, production overcapacity, excess inventory levels and accelerated erosion in average selling prices, which can have a material adverse
effect on our business. These factors have in the past and may in the future cause substantial fluctuations in our revenue and results of operations.

We may not accurately forecast demand for our products, and as a result may hold excess inventory or suffer from product shortages. The level of inventory required in our business is sensitive to changes in the actual demand for our products compared with our
forecast of sales of those products. In addition, we supply a wide range of products which are not interchangeable between customers or applications. Accurate forecasting of demand in the volatile and dynamic sectors in which we operate can be very
difficult, particularly in times of rapidly changing economic conditions and uncertain demand from end consumers for retail products. Actual demand from our customers compared to forecasted demand has the potential to vary significantly. If changes
in actual market conditions are less favourable than those projected, we will hold higher levels of inventory than is required to satisfy customer demand. This may result in us holding inventory which we are unable to sell, due to customers no
longer requiring the product held in inventory. We may need to reduce the selling price of the surplus products in order to sell the inventory, and this may still not be sufficient incentive to customers to enable us to sell the excess inventory. In
this situation we may suffer reduced margins, inventory write-offs or both. Similarly, in time of growing demand, either generally or for particular products, we may not order sufficient inventory to satisfy customer requirements and as a result not
be able to meet customer orders in a timely manner. Obtaining additional supply may be costly or impossible, and failing to meet customer needs may adversely affect customer relationships and reduce our revenue, which would adversely affect our
results of operations. The financial difficulties or failure of our distributors could cause us to suffer an immediate financial loss and affect our
ability to supply products to end customers. We supply a significant proportion of our products to end customers through third party
distributors. Our largest distributor accounted for approximately 12% of our net revenue in 2009 and 24% in 2008. Our distributors are wholly independent third parties, which supplement our own direct marketing and sales efforts. The current
economic environment presents significant challenges to the stability of distributors. Uncertain demand patterns, restrictions on credit terms and slowdown in orders represent a significant


adverse trading environment for distributors which could affect their ability to continue in business. We are subject to the risk that one or more of our distributors could suffer serious
financial difficulties, or be unable to continue in business. In these circumstances, our own business with our customers would be disrupted if they are unable to obtain our products on a timely basis. We may be unable to collect amounts due from a
failed distributor for products which have been supplied or to recover those products in default of non-payment. Each of these events could have a material adverse effect on our business and financial performance. We may fail to compete successfully in a very competitive market. The market for our products is highly competitive and rapidly evolving. We compete in different product lines to varying degrees on the following characteristics:  ·

price;  ·

technical performance;  ·

product features;  ·

product system compatibility;  ·

product design and technology;  ·

timely introduction of new products;  ·

product availability;  ·

manufacturing yields; and  ·

sales and technical support. Given the intense competition in the semiconductor industry, if our products are not selected by current or potential customers, our business, financial condition and results of operations will be materially adversely affected. We are seeing increased competition throughout the market for wireless connectivity products. The increased competition could result in
more

DIRECTORS REPORTRISK FACTORS continued






pronounced price reductions, reduced margins and/ or loss of market share. Within our markets, we face competition from public and private companies, as well as the in-house design efforts of our
customers. A number of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and other resources than us. We may fail to compete successfully, which could materially adversely affect our business and
financial performance. Some of our customers could become our competitors. Some of our customers are also large integrated circuit suppliers and some of our large customers already have expertise in-house in the technologies which we develop and supply. These large
customers have longer operating histories, significantly greater resources and name recognition, and a larger base of customers than we do. The process of licensing our technology to and support of such customers entails the transfer of technology
that may enable them to become a source of competition to us, despite our efforts to protect our intellectual property rights. Each new design by a customer presents a competitive situation. In the past, design win opportunities have been lost to
divisions within our customers and this may occur to us in the future. If our customers become our competitors, we may lose them as customers and they may no longer license products from us, or in the same volumes, which may have a material adverse
effect on our results of operations. Our technologies could decline in importance or be superseded by an alternative technology. We derive the majority of our revenue from sales of our Bluetooth- and GPS-based products. We would be materially adversely affected if either of these
technologies were to decline, or be replaced entirely, as the prevailing technology for short-range wireless communication and location-based services, or if superior technologies were developed that resulted in our products being less competitive.
We continue to invest in the development of next generation products, but our future products may not gain market acceptance, we may fail to identify markets for our products or our products could be rendered obsolete by the development of a new,
superior technology.


The market for GPS-based location awareness capabilities in high-volume consumer and commercial applications may not
develop as quickly as we expect. The market for GPS-based location awareness technology in high-volume consumer and commercial
applications is continually evolving and its potential is uncertain. Many of these GPS-based applications have not been commercially introduced or have not achieved widespread acceptance. The success of our GPS-based business depends on the rapid
development of this market. We cannot predict the growth rate, if any, of this market. The development of this market depends on several factors, including government mandates such as E911 mandate in the United States and E110 mandate in Japan, the
development of location awareness infrastructure by wireless network operators and the availability of location-aware content and services. If the market for high-volume consumer and commercial GPS-based applications fails to develop in a timely
manner, the growth and success of our business may be limited. Our technologies could be integrated into other integrated circuits. The Bluetooth and GPS standards have each evolved over the time since their first introduction and an ever increasing array of features have been added
to the chips required by our customers. At the same time, our ability to optimize chip design and industry-wide manufacturing improvements means that the physical size of the Bluetooth-only and GPS functions has been progressively reduced. If our
products cease to be used as an anchor point around which to integrate other technologies, or if the functions that our products support were ultimately integrated into one of the cellular chips in the phone, our business would be
materially adversely affected. Similarly, the emerging technologies which we have under development or which we may release in the future, may be integrated into one of the cellular chips in the phone, which could also materially adversely affect
our future business. Government regulation of our technologies may increase our cost of doing business and/or decrease demand for our products. The market for our technologies is and in the future may be increasingly affected by controls on exports or restrictions on application
of measures adopted by governments or other supra-national organisations. For example, GPS technology is restricted and its




CSR plc Annual Report
and Financial Statements 2009



54



---






export is controlled. Our business may be impacted by government regulations because its technology relies on the GPS satellite network and radio frequency bands, aspects of which are controlled
or regulated by the U.S. and other governments. The U.S. government may restrict specific uses of GPS technology in some applications for privacy or other reasons and block the civilian GPS signal at any time or in hostile areas. In December 2004,
the President of the United States authorized a new national policy that established guidance and implementation actions for space-based positioning, navigation, timing programmes, augmentations and activities for U.S. national and homeland
security, civil, scientific, and commercial purposes. Government regulation and other actions taken in relation to the GPS satellite network and other radio frequency bands used by our technologies such as Bluetooth could interrupt or increase our
cost of doing business and/or decrease demand for our products, any of which could materially adverse effect on our business. Personal privacy concerns
may limit the demand for consumer and commercial applications and demand for our products. Our products rely on the ability to receive,
analyse, transmit and store information. Consumers may not accept some applications because of concerns that our products could compromise their personal privacy. For example, consumers could consider that our products allow for unwanted
interception or intrusion into transferred data, may enable unwanted access into the devices being used, or may allow the consumers location to be tracked and that this information could be collected, stored and used by others against the
wishes of the consumer concerned. Governments may disallow specific uses of these technologies for privacy or other reasons or could subject the industry to regulation. If consumers view our products as a threat to their privacy, demand could
decline, which could materially adversely affect our operations and financial results. Part of our business uses a royalty-based business model, which
has inherent risks. In recent periods we have derived a portion of our net revenue from large customers in the wireless markets from
royalties paid by licensees of our technology. We depend on our ability to structure, negotiate and enforce agreements for the determination and payment of royalties. If a significant licensee


terminates its relationship with us, demands price reductions, decides to adopt a competitors technology over our technology or if we are unable to negotiate and renew existing agreements
with significant licensees, our royalty revenue, gross margins and net income could be adversely impacted. We face risks inherent in a royalty-based business model, many of which are outside of our control. We are highly reliant upon the success of our customers products. We rely on equipment manufacturers to select our products to be designed into their products. Even if an equipment manufacturer selects our product, the customers product may not be commercially successful. As a
result, sales of our products are largely dependent on the commercial success of our customers products. If the customers products are unsuccessful, our business may be materially adversely affected. Our business and future operating results may be materially adversely affected by events outside of our control. We conduct our business in many foreign territories. Our wireless solutions are supplied to end customers based in diverse locations, who in turn
market their products worldwide into many countries. Our own operations and also the success of the customers products (and therefore our financial success) may be affected by changes in economic, financial and political stability in various
countries or geographic regions. Adverse changes in one or more of these countries or in geographical regions generally, including, for example, economic decline, failing financial systems, political upheaval, civil unrest, terrorism, wars,
outbreaks of diseases or natural disasters, could have a material adverse effect on our ability to conduct our business and on our financial and operational performance. For example, we procure supplies from, conduct business in or otherwise derive
significant revenue from China and Taiwan. While the Chinese government has pursued economic reforms for a number of years, it continues to exert considerable direct and indirect influence on the economy. Future actions by the Chinese government,
including the reversal of economic reforms and return to a more centrally planned economy, could have a significant effect on economic conditions in China, which may have a material impact on our business and revenue. Further, developments

DIRECTORS REPORTRISK FACTORS continued






that adversely affect the political stability or economic conditions in Taiwan, including the potential impact of natural disasters on the geographically concentrated operations of our suppliers,
could materially and adversely affect our business and revenue. Risks related to owning CSR ordinary
shares As we do not currently intend to list our ordinary shares on any U.S. national securities exchange or create a sponsored ADR program, a U.S.
trading market for our ordinary shares may not develop. We do not currently intend to list our ordinary shares on any U.S. securities
exchange, and do not have current plans to create a sponsored American Depositary Receipt program for our ordinary shares. As a result, an active U.S. trading market for our ordinary shares may not develop. Furthermore, it may be time-consuming and
expensive for U.S. holders of our ordinary shares to dispose of their ordinary shares. We may decide in the future to terminate our reporting
obligations under the Exchange Act. We may decide to deregister the ordinary shares with the SEC and terminate our reporting obligations
under the Exchange Act if we comply with the SEC requirements to effect such termination. For example, because we have filed this Annual Report on Form 20-F with the SEC, following twelve months after the effective date of the registration
statement on Form F-4 that we filed in June 2009, we will have the ability to terminate our registration under the Exchange Act if there are less than a certain number of resident U.S. holders of our ordinary shares or if the trading volume of such
shares is below a certain level. Were we to terminate our registration under the Exchange Act, we would no longer be subject to SEC reporting requirements (for example, the requirement to file annual reports on Form 20-F and information regarding
certain material events on Form 6-K) and other obligations (for example, those arising under the Sarbanes-Oxley Act of 2002) of an SEC reporting company. We may be treated as a passive foreign investment company. As a company domiciled outside of the United States with substantial
cash assets, there is an ongoing risk that the Company may be treated as a passive foreign investment company (often referred to as a PFIC) for U.S. federal income tax purpose s depending on the


ratio of our share price (which affects the valuation of certain assets including goodwill) to our holdings of cash and liquid assets such as bank deposits and marketable securities. A non-U.S.
corporation generally will be considered a PFIC for any taxable year in which 75% or more of its gross income is passive income, or 50% or more of the average value of its assets are considered passive assets (generally, assets that
generate passive income). This determination is highly factual, and will depend upon, among other things, our market valuation and future financial performance. We believe we were not a PFIC for the taxable year ended in December 2009, but if we
were to be classified as a PFIC for any future taxable year, holders of CSR ordinary shares who are U.S. taxpayers would be subject to adverse U.S. federal income tax consequences. Shareholders in countries other than the United Kingdom will suffer dilution if they are unable to participate in future pre-emptive equity offerings. Under English law, shareholders usually have pre-emptive rights to subscribe on a pro rata basis in the issuance of new shares for cash. The exercise of pre-emptive rights by certain shareholders
not resident in the United Kingdom may be restricted by applicable law or practice in the United Kingdom and the United States. In particular, the exercise of pre-emptive rights by U.S. shareholders would be prohibited unless the rights offering is
registered under the Securities Act or an exemption from the registration requirements of the Securities Act applies. If no exemption applies and we do not wish to register the rights offering, shareholders in the United States may not be able or
permitted to exercise their pre-emptive rights. We are also permitted under English law to disapply pre-emptive rights (subject to the approval of our shareholders by special resolution and investor committee guidance on the limits of any such
disapplication) and thereby exclude certain shareholders, such as overseas shareholders, including in the United States, from participating in a rights offering (usually to avoid a breach of local securities laws). Your rights as a CSR shareholder will be governed by English law, which may differ from the laws of other jurisdictions. Because CSR is a public limited company incorporated under the laws of England and Wales,




CSR plc Annual Report
and Financial Statements 2009

---






your rights as a shareholder will be governed by English law and by CSRs memorandum and articles of association. These rights differ from the typical rights of shareholders in companies in
other jurisdictions. For further information with respect to our ordinary shares, see Memorandum and Articles of Association. Shareholders
in countries outside of the United Kingdom may have difficulty suing us or our directors, or in enforcing judgments obtained outside of the United Kingdom. CSR is domiciled in the United Kingdom, and most of our directors are residents of the United Kingdom. As a result, it may not be possible for shareholders in other countries to begin litigation against us or our directors,
or to obtain discovery of relevant documents and/or the testimony of witnesses. Shareholders in other countries may have difficulties in enforcing judgments obtained outside of the United Kingdom. The market value of our ordinary shares may be adversely affected by fluctuations in the exchange rate between the pound sterling and other currencies. Fluctuations in the exchange rate between the pound sterling and other currencies will affect the market value of our ordinary shares when expressed in
that other currency. If the relative value of the pound sterling to another currency declines, the equivalent value against the pound sterling price of our ordinary shares traded on the London Stock Exchange will also decline. Although our current
policy is not to pay dividends, any dividends we may decide to pay in the future would be paid in pounds sterling, which would


be subject to the same risks. Shareholders outside the United Kingdom who sell their shares must do so on the London Stock Exchange against payment in pounds sterling. As a result of any
fluctuations in the exchange rate between the currency of choice of the shareholder and the pound sterling, non-U.K. resident shareholders may receive a reduced value upon the sale of their ordinary shares and will also incur transaction costs when
converting the pound sterling into another currency. The market price of our ordinary shares is volatile. Our shareholders may be unable to resell
their shares at or above the price at which they acquired them. The stock market in general and our ordinary shares in particular have
recently experienced significant price and volume volatility. Our ordinary shares are subject to significant fluctuations due to many factors, including but not limited to fluctuations in operating results, announcements regarding new products,
product enhancements or technological advances by us or our competitors, changes in earnings estimates by market analysts, and general market conditions or market conditions specific to particular industries. Our share price is subject to
speculation in the press and the analyst community, changes in recommendations by financial analysts, changes in investors or analysts valuation measures for our stock, changes in global financial markets and global economies and general
market trends unrelated to our performance. Technology stocks have experienced wide fluctuations in prices, which sometimes have been unrelated to their operating performance. The market price of our ordinary shares could be adversely affected by
these factors and fluctuations.

DIRECTORS REPORTCORPORATE GOVERNANCE

Directors report  Corporate governance




Chairmans introduction Your Board is accountable to the Companys shareholders for creating and delivering sustainable shareholder value through the management of the
Groups business. We are committed to high standards of corporate governance which we recognise is fundamental to business integrity and to enabling the Group to operate successfully. The Company expects all directors and employees to act honestly, with integrity and fairness and this is supported by established policies and is
reinforced through a culture which is driven from the Board members across the organisation. As an increasingly global business, the Group strives to act in accordance with the laws and customs of the countries in which it operates; adopt proper
standards of business practice and procedure and respect the culture of every country where it does business. The following report and
the report of the Remuneration Committee on pages 73 to 85 explains how the Board operates, the roles of the Board members and how the Board and its Committees function to ensure compliance with the principles of corporate governance. It also sets
out how we encourage our employees across the Group to contribute to ensuring that the Group as a whole operates to high standards of governance, in their participation within the business of the Board and its Committees and as individuals through
their responsibility to support these principles. Ron Mackintosh Statement of compliance The Companys shares are listed on the London Stock Exchange and
therefore, under the Listing Rules of the Financial Services Authority, the Board must report on compliance with the provisions set out in Section 1 of the 2008 Combined Code on Corporate Governance (the Code), which are
appended to the Listing Rules. In addition to complying with UK corporate governance requirements, the Company must also follow US
securities laws and regulations due to registration of its ordinary shares with the US Securities and Exchange Commission, although it is not listed on a US stock exchange.


Other than the provision relating to the balance of executive and non-executive directors on the
Board over the period between 27 May 2009 and 1 January 2010, the Board has complied with the provisions of the Code. On 27 May 2009, Mr David Tucker, a non-executive director, retired from the Board. As a result, from that date, the
Board had a greater number of executive directors than non-executive directors. On 26 June 2009, at the time of the completion of the acquisition of SiRF Technology Holdings, Inc., Mr Diosdado Banatao and Mr Kanwar Chadha were appointed as
directors; Mr Banatao as a non-executive director and Mr Chadha as an executive director. Following the appointments, the balance of executive and non-executive directors remained non-compliant with the Code as the Board remained composed of more
executive directors than non-executive directors. As explained in the Circular issued to shareholders on 4 June 2009, in deciding
to offer Messrs. Banatao and Chadha positions as directors of the Company, the Board considered that their knowledge and experience in the management of SiRF and their extensive understanding of the semiconductor industry will be beneficial not
only to the integration of CSR and SiRF, but also to the development of the business of the combined company going forward. When considering the appointment of Mr Banatao to the role of a non-executive director, the Board discussed his
independence from management at the time of appointment. The Board is satisfied that Mr Banatao is independent of the Company, the Board and management, since he has not had any previous relationship or dealings with the Company. Following a suitable period after these appointments, and with due regard and consideration given to the balance of skills and experience, the Board
will address the appointment of an additional non-executive director during 2010. The Board considers that, notwithstanding the non-compliance with the provisions of the Code, an appropriate balance of skills and experience has been in place to
enable the Board to perform its responsibilities effectively.

DIRECTORS REPORTCORPORATE GOVERNANCE continued






The Board believes that succession planning should be an area for focus, particularly in light of the acquisition of SiRF and as part of
this recognition, a proposal on possible steps was developed in November 2009, which has been approved for execution in 2010. As a result, the Board expects to consider this matter further during 2010. The Board is aware of the review of the Code conducted by the UK Financial Reporting Council which was completed and published in 2009. The Board will
reflect the revisions to the Code in its practices during the course of 2010 and will report on these matters in the next annual report issued in 2011 to shareholders. Executive Ethics Policy All employees of the Group, including the executive directors and senior officers, must comply with the Groups Ethics Policy recently adopted following the Companys registration with the US Securities and
Exchange Commission. In addition, the Company has adopted an Executive Ethics Policy that applies to executive directors, senior officers and other specified employees and is intended to meet the code of ethics requirements of
Section 406 of the US Sarbanes-Oxley Act. A copy of the Executive Ethics Policy may be found at www.csr.com/ethicspolicy. The
following statements describe how the Board operates and the respective roles of the Chairman, non-executive and executive directors. The Board As at 1 January 2010, the Board comprised ten members, being the
Chairman, Mr Ron Mackintosh, five executive directors and four non-executive directors. Of those in post as at 1 January 2010, eight directors including Mr Mackintosh had served throughout the year. The four executive directors in office at 1 January 2010 who had served throughout the year were Mr Joep van Beurden, Chief Executive
Officer, Mr Will Gardiner, Chief Financial Officer, Mr James Collier, Chief Technical Officer and Mr Chris Ladas, Operations Director. Mr Kanwar Chadha was appointed as an executive director on 26 June 2009. The three non-executive
directors who served throughout the year, each of whom is considered


independent of management, were Mr Anthony Carlisle, Mr Sergio Giacoletto-Roggio and Mr Andrew Allner. Mr Diosdado Banatao was appointed as a non-executive director on 26 June 2009. Mr Mackintosh has served as Chairman of the Board since May 2007 and as a non-executive director of the Company since May 2004. In the
opinion of the Board, on each of his appointments as a non-executive director and as Chairman, Mr Mackintosh was independent of management. The Board is satisfied that Mr Mackintosh is able to devote the necessary time commitment to the role of
Chairman of the Board. Mr Tucker served as the Senior Independent Director and Chairman of the Audit Committee until he retired from
the Board on 27 May 2009. With effect from 27 May 2009, Mr Anthony Carlisle was appointed the Senior Independent Director and Mr Andrew Allner, a chartered accountant with recent and relevant financial experience, was appointed
Chairman of the Audit Committee. Mr Gardiner is the director responsible for health and safety. The directors possess diverse business experience in spheres complementary to CSRs activities, as well as other sectors. Biographies of the
directors are shown on pages 59 and 60. Mr Brett Gladden served as Company Secretary throughout the year. The Conduct of the Business of the Board The Board meets regularly during the year as well as on an adhoc basis as
required by time critical business needs. During the course of 2009 regular meetings were augmented by additional meetings to enable discussion with other Board members and advisers on the proposed acquisition of SiRF. This included understanding
the implications for the Company registering with the US Securities and Exchange Commission, the relisting of the Companys ordinary shares on the London Stock Exchange and the development and review of associated documents in regard to these
matters and the issue of a circular to shareholders seeking approval for the acquisition. The Board is responsible to shareholders for
the effective and proper management and control of the Company and Group and has a formal schedule of matters reserved for its decisions. Its primary role is to determine and review strategy and policy, consider

acquisitions and disposals, assess requests for major capital expenditure and give consideration to all other significant financial matters. This process is undertaken following discussions in
conjunction with senior executive management, who in turn are responsible for the day-to-day conduct of the Groups operations and for reporting to the Board on the progress being made in meeting the objectives. The Chairman ensures that the Board functions effectively, overseeing the timely and effective provision of information to the Board and that the
business of the Board is properly conducted. A comprehensive file of briefing papers and a meeting agenda is provided for each director in advance of each meeting. Decisions are taken by the Board, taking into account, where appropriate, the
recommendations of its Committees and advice from external consultants and executive management. The non-executive directors of the
Board have diverse business, financial and technical experience, details of which are summarised on pages 59 and 60 and they each play a full role in the consideration of matters brought before the Board. This includes:  ·

considering, approving and monitoring performance against strategic objectives through detailed reviews conducted at Board level;  ·

providing entrepreneurial leadership within a framework of prudent and effective controls, which enable risks to be assessed and managed; and  ·

setting the Groups values and standards and ensuring that its obligations to its shareholders and other stakeholders are understood and
met. Non-executive directors are expected to constructively challenge and contribute to the development of strategy,
scrutinise the performance of management in meeting agreed goals and objectives and monitor the reporting of performance. The Board
regularly reviews strategy as part of its normal business. This includes holding two offsite meetings each year, the agendas for which cover a


broad range of financial, commercial and technical aspects concerning the strategic objectives for the Group. These meetings are held in the summer and autumn, with different members of the
management team attending, depending on the topics for discussion. With the agreement of the Board, during 2009, individual
non-executive directors provided specific support and advice on discrete issues being considered by the Company, according to their particular skills and experience. Mr Giacoletto-Roggio acted in an advisory capacity to the Integration Committee
(the remit of which is explained in more detail on page 68) in the planning of the integration of the Company and SiRF and he was able to report on these matters to the Board as a whole. During October 2009, the Chairman travelled with the CEO to a
number of offices around the Groups locations worldwide to meet with staff to discuss the Companys vision and strategy and also progress on the integration. Following the acquisition of SiRF, the Board as a whole also travelled to
California for a meeting, the business of which included discussions on the future strategy for the enlarged group. Whilst in California, the Board also visited the Groups offices in San Jose to hold meetings with members of staff who had
joined as a result of the acquisition of SiRF and attend demonstrations on products under development. Independence of non-executive
directors and segregation of duties In accordance with the provisions of the Code, consideration has been given to the independence of
all the non-executive directors. The Board considers all the non-executive directors to be independent of management and free from any business or other relationship that could materially interfere with the exercise of independent judgement. The division of responsibilities between the non-executive Chairman and Mr van Beurden, CEO, is sufficiently clear in the opinion of
the Board that it is not required that they be formally documented. The Chairman is responsible for the running and leadership of the Board. The CEO is responsible for leading and managing the business within the authorities delegated by the Board.

DIRECTORS REPORTCORPORATE GOVERNANCE continued






The CEO has day-to-day responsibility for the Group and has reporting to him executive management who in turn are responsible for the
performance of discrete commercial and operational activities of the Group. This includes management teams responsible for reviewing the implementation of established objectives and assessing performance of particular functions against those
objectives. Representatives from these teams in turn attend and report to a weekly executive leadership forum which includes the executive directors. The CEO also meets regularly with the managers and leaders in various established forums that fit
with the operational cycles of the Group. The CEO formally reports at each meeting of the Board on salient matters arising from the execution of his responsibilities. The Board met 11 times during the year and the attendance of each of the directors is shown on page 72. Evaluation of the Performance of the Board In the final quarter of 2009, the Board undertook a formal process of performance evaluation. Each director who had served to that point throughout the year completed a confidential survey prepared
by the Company Secretary, covering a wide range of matters associated with the activities and conduct of the Board and its Committees. The process was conducted without reference to external agencies. The merits of using external agencies to support
the evaluation process is reviewed from time to time, and will be looked at in more detail during 2010. A detailed summary of the responses from each participating director was prepared by the Company Secretary which was considered by the Board in
December 2009 as an agenda item which was led by the Chairman. The overall conclusion was that the Board and its Committees were
performing appropriately, whilst proposing that additional attention be given to certain areas, including the development of Group-wide measures for succession planning, in particular for senior roles within the organisation. The Board also
recognised the importance of appointing an additional non-executive director, which will be addressed during 2010 as explained above. The Chairman holds regular meetings with all the directors individually. In addition, prior to the year end,


the Chairman held a meeting with the non-executive directors to discuss the performance of the executive directors which concluded that they were each performing well. In December 2009, the non-executive directors, led by the Senior Independent Director, met in the absence of the Chairman to appraise the performance
of Mr Mackintosh as Chairman. The non-executive directors concluded that he had performed well. Policy
on Appointment and Re-Appointment In accordance with the Companys Articles of Association, all directors are required to retire
and submit themselves for re-election at least once every three years. It is the policy of the Board that non-executive directors are
appointed for an initial term of three years. The directors performance is assessed throughout the term. An appointment may, if performance is satisfactory, be extended for a further period not exceeding three years. Non-executive directors
should not generally serve for more than nine years. At this years Annual General Meeting Mr Mackintosh will be retiring in
accordance with the Companys Articles of Association and will be offering himself for re-election. As part of its formal business in February 2010, the Board considered and supported Mr Mackintoshs re-appointment for a further three year
term. The initial three year term of Mr Sergio Giacoletto-Roggio concludes in January 2010. As part of its formal business in December 2009, the Board considered and approved the renewal of Mr Giacoletto-Roggios appointment for a further
three year term, effective from 4 January 2010. At this years Annual General Meeting Mr Giacoletto-Roggio will be retiring in accordance with the Companys Articles of Association and will be offering himself for re-election. Mr Diosdado Banatao who was appointed a non-executive director on completion of the acquisition of SiRF has a letter of appointment
effective for a three year term from 26 June 2009. In accordance with the Companys Articles, Mr Banatao will be offering himself for election at the 2010 Annual General Meeting being the first General Meeting of the Company since his
appointment.

Mr Kanwar Chadha was appointed an executive director on completion of the acquisition of SiRF. In accordance with the Companys
Articles of Association, Mr Chadha will be offering himself for election at the 2010 Annual General Meeting being the first General Meeting of the Company since his appointment. Further information on each of the directors standing for re-election and election are set forth in the Notice of the Annual General Meeting which is in a separate document issued to all
shareholders. On appointment, all directors are asked to confirm they have sufficient time to devote to their duties which, along with
their duties and roles are confirmed in their letter of appointment. They are also advised that they have access to the advice and services of the Company Secretary and, in addition, that they are entitled to seek independent professional advice in
the furtherance of their duties, if necessary, at the Companys expense. As part of their induction, the directors are provided with a detailed file explaining their role and duties, in addition to background information on the Company and
Group as well as the function and recent deliberations of the Board and its committees. In addition, where appropriate, meetings with advisers to the Company and Board are arranged to assist in briefing a director on appointment. Directors are also provided with information and assistance in the event of any change in their role. Indemnities to Directors In accordance with the Companys Articles of Association, directors are granted an indemnity from the Company to the extent permitted by law in respect of liabilities incurred as a result of the performance of their
duties in their capacity as directors to the Company. The indemnity would not provide any coverage to the extent that a director is proven to have acted fraudulently or dishonestly. The Company has also arranged insurance coverage in respect of
legal action against the directors and officers. Communications with shareholders Principally via the executive directors, the Company seeks to build on a mutual understanding of


objectives with its major shareholders through regular meetings and presentations following announcements of each quarters results. The Senior Independent Director, Mr Anthony Carlisle, is available to meet institutional shareholders should there be unresolved matters they wish to
bring to his attention. The Board is also appraised of discussions with major shareholders to ensure that executive and non-executive directors consider any matters which might be raised by those shareholders and to enable all directors to
understand shareholders views. This includes feedback from the meetings attended by executive directors and the Chairman, in addition to reports from the Companys advisers on their engagement with shareholders on behalf of the Company.
During 2009, the Chairman of the Remuneration Committee met with a number of shareholders to discuss the Boards remuneration policy, which included a review of changes introduced in 2009 to aspects of the remuneration of executive directors,
primarily concerning the performance conditions applying to the vesting of share options and share awards, the details of which were disclosed in the report of the Remuneration Committee for the period ending 2 January 2009. Non-executive directors attend the Annual General Meetings and will also make themselves available to meet with shareholders on other occasions where
requested. Corporate information is available on the Companys website, www.csr.com. Committees
of the Board The Board has three Committees, Remuneration, Audit and Nomination. Throughout the year, the Chairman and each of Mr
Allner, Mr Carlisle and Mr Giacoletto-Roggio were members of the Remuneration and Nomination Committees. Mr Mackintosh attends meetings of the Audit Committee by invitation. Mr Tucker was a member of the Remuneration and Nomination
Committees and Chairman of the Audit Committee until he stood down from the Board on 27 May 2009. In accordance with the Code, the
duties of the Committees are set out in formal terms of reference. These are available from the Company Secretary and can be found on the Companys website, www.csr.com. Membership of the Committees is

shown on page 59 and 60. The Company Secretary acts as secretary to each of the Committees. The terms of reference are each subject to annual review. Remuneration Committee Mr Sergio Giacoletto-Roggio is the Chairman of the Remuneration Committee, which position he has held since September 2007. The other members of the Committee at 1 January 2010 were Messrs Allner, Carlisle and
Mackintosh. The principal function of the Remuneration Committee is to establish and review the terms and conditions for the executive
directors, and the overall policy framework for the remuneration of other senior executives and the Group as a whole. The Remuneration Committee met four times during the year and the attendance of its members is shown in the table on page 72. The report to shareholders on the role of the Remuneration Committee, how directors are remunerated, together with details of
individual directors remuneration are shown on pages 73 to 85. Nomination Committee Mr Ron Mackintosh is the Chairman of the Nomination Committee, which position he has held since 2 May 2007. The other members of the Nomination
Committee at 1 January 2010 were Messrs Allner, Carlisle and Giacoletto-Roggio. The Nomination Committee meets as appropriate to
consider appointments to the Board and to consider succession planning at senior levels within the Company. The Nomination Committee reviews the composition of the Board, particularly in relation to the diversity of skills, experience and terms of
office and seeks to ensure that both executive and non-executive directors have the necessary skills and attributes for the future success of the Group. The Nomination Committee retains external search consultants as appropriate to assist the Committee in identifying candidates for appointments to the Board. During 2009, the Nomination Committee did not meet separately, but did meet as part of the formal proceedings of the Board on one occasion to


consider the appointments of Mr Banatao and Mr Chadha. As explained on page 61, the appointments of both Mr Banatao and Mr Chadha, were considered in conjunction with the acquisition of SiRF
and also the extensive experience and knowledge which they were both able to bring to the combined company going forward. As a result, the Nomination Committee did not consult with external agencies in regards to their appointments. Audit Committee Mr Andrew Allner is the Chairman of the Audit Committee, a position he has held since 27 May 2009. Mr Allner was appointed following the retirement from the Board of Mr David Tucker who had acted as Chairman of the Audit
Committee since February 2004. The Board has determined that Mr Allner, a Chartered Accountant, has recent and relevant financial experience for the purposes of the Code and is an audit committee financial expert for the
purposes of US securities laws. The Board has further determined that for the purposes of US securities laws, although CSR is not
listed in the United States, Mr Allner is independent in accordance with the definition of independence in Rule 5605(a)(2) of the listing rules of the NASDAQ Stock Market. The other members of the Audit Committee at 1 January 2010 were Messrs Carlisle and Giacoletto-Roggio. Mr Mackintosh, Chairman of the Board, attends meetings of the Audit Committee by
invitation. The experience and expertise of the members of the Audit Committee are summarised on pages 59 and 60. The attendance of its members is shown in the table on page 72. Role of the Audit Committee The Audit Committee is responsible for the development, implementation and monitoring of the Companys policy on external audit and for overseeing the objectivity and effectiveness of the auditors.

assessment of their findings and recommendations, where relevant.

The Audit Committee recommends the appointment and re-appointment of the Groups external auditors and considers the scope of their
audit work, the terms of their appointment, their fees and the cost effectiveness of their work. The Audit Committee also monitors the
effectiveness of the Groups internal control systems, accounting policies and practices, risk management procedures and compliance controls, as well as the statement on internal controls before it is agreed by the Board for each years
annual report. A detailed agenda of matters for discussion at the meeting, together with supporting papers is provided in advance of
each meeting. The agenda incorporates a range of standard business items considered at each meeting. Routine business items include reports from the CFO and Internal Auditor as well as a draft form of the announcement on the Groups financial
results for the relevant quarter. In addition the Audit Committee addresses a number of other items as part of its schedule of business through the course of a year, such as risk management, business continuity planning, treasury policy and
procedures, tax planning and the Groups policy manual as well as such ad-hoc matters as are deemed appropriate. The schedule of agenda items for the calendar year was last reviewed and approved by the Audit Committee in July 2009. The Audit Committee invites the Chief Executive Officer, the Chief Financial Officer, the Internal Auditor and senior representatives of the
external auditors to attend meetings as appropriate to the business being considered. In addition, the Audit Committee has the right to invite any other employees to attend meetings where this is considered to be appropriate. The Conduct of the Business of the Audit Committee The Audit Committee met four times during the year in the execution of its responsibilities. The more material matters considered and any proposals for action were reported by the Chairman of the
Audit Committee to the subsequent meeting of the full Board. During 2009, in addition to the routine business, the Audit Committee received reports on additional matters falling within its terms of reference, the primary focus of which was initially
information in connection with the proposed acquisition of SiRF Technology Holdings Inc and, following completion of the acquisition, on


progress with the integration of the two companies, which included financial, tax and treasury, business systems and wider commercial matters. More details on this work is set out below. The Audit Committee reviews all proposed announcements to be made by the Group to the extent they contain financial information, but
primarily the announcement of the Groups results released each quarter to the markets and investors. Each quarter, as part of its routine business, the Audit Committee receives a detailed report from the Chief Financial Officer on the
performance of the Group. In addition to a summary of the balance sheet and income statements, the report incorporates detailed analysis on a range of key metrics which tracks the performance of the Group and its business units. This information
forms part of the discussions by the Audit Committee to ensure that material matters are properly considered and discussed with management and where appropriate the external auditors. The information and the discussions in turn supports the
understanding of the Audit Committee on the nature of disclosures which should be made in the Groups financial results. During
the year, the Audit Committee considered and was advised on the work which was conducted in connection with the submission of the Registration Statement on Form F-4 to the US Securities and Exchange Commission and separately the approval and release
of both the Circular to shareholders advising on the proposed acquisition of SiRF and the Prospectus in connection with the re-admission to listing of the Companys ordinary shares on the London Stock Exchange in accordance with the
requirements of the UK Listing Rules. The Audit Committee monitors the effectiveness of the internal audit function, approving the
annual internal audit plan, and thereafter reviewing reports on the results of internal audit work which has been conducted. These reports are provided on a quarterly basis and up-date the Audit Committee on the progress in addressing any
recommendations that have been made arising from the audits which have been conducted. At an early stage in the assessment of the tasks
and risks associated with integrating CSR plc with SiRF,

DIRECTORS REPORTCORPORATE GOVERNANCE continued






the Board and Audit Committee recognised the importance of establishing dedicated internal resource whose responsibility it would be to develop an integration plan and facilitate the
implementation of that plan post acquisition. This was delegated to an Integration Committee, which was resourced from within the
Company whilst being supported by external consultants. In the course of the planning and execution of the integration programme, it was felt appropriate that the Internal Auditor should be seconded to the Integration Committee. This was regarded as
appropriate based on his knowledge of the business of CSR and the contribution he was able to make in implementing best practices within the enlarged company in addition to facilitating the transition of policies, procedures and controls from two
organisations into one. Acting in this capacity the Internal Auditor was also able to report to senior management and the Audit Committee on the progress of integration. As a result, the Internal Auditor was seconded for a significant proportion of
his time to the Integration Committee. The Audit Committee received detailed reports arising from the work of the Integration Committee
on various aspects associated with both the planning and execution of the integration of the separate businesses and operations of CSR and SiRF following completion of the acquisition. Particular attention was given to the timely integration of
financial systems in order to best ensure accurate recording and reporting of financial matters, within a consistent framework of accounting policies which applied for the enlarged group as a whole. Since the Company became subject to the reporting requirements of the US Securities Exchange Act of 1934, the Audit Committee has received reports
from management regarding the Companys compliance with requirements under the Exchange Act (including those rules and regulations that apply by reason of the US Sarbanes-Oxley Act of 2002) that relate to financial reporting and other
disclosure matters. These requirements relate among other things to disclosure controls and procedures (which became applicable in June 2009) and internal control over financial reporting (which will apply beginning in the current fiscal year).


The Audit Committee approved an internal audit plan in July 2009, following completion of the
acquisition of SiRF. The plan provided for reviews of aspects of the controls and procedures of the newly acquired company to ensure an appropriate level of confidence at an early stage in areas which the Audit Committee considered to be of
particular importance. As part of the adoption of the plan, the Audit Committee also supported the utilisation of external resources to assist in timely execution and reporting. During the year, the Audit Committee appointed Ernst & Young LLP to conduct an internal audit of the Companys Treasury Policy and Procedures. The use of external advisers was
considered appropriate given the increasing complexity of Treasury matters affecting the Company and to assist management in a thorough understanding of the Treasury practices and policies within SiRF. The findings and recommendations from that
audit were considered at the meeting of the Audit Committee held in October 2009. Reflecting a combination of management comments and the recommendations of the review, the Audit Committee considered a revised Treasury Policy which was subsequently
approved by the Board in October 2009. Following the completion of the integration with SiRF, the present Internal Auditor has been
appointed to another role within the finance department of the Group. Steps are being taken to appoint a new internal auditor and it is anticipated that an appointment will be made in the spring of 2010. In the interim, aspects of the internal audit
plan for 2009 continue to be supported by external professional resources. The routine business of the Committee at each meeting
includes an up-date on litigation concerning the Group. In the time leading up to the proposed acquisition of SiRF, the Board considered and took advice on litigation as it concerned SiRF. Following the acquisition, at the proposal of the Committee,
a sub-committee of the Board led by the Chairman has been established which meets to consider matters connected with material litigation, which has as invited attendees members of the Groups executive management.

Interaction with the External Auditors During 2009, as part of its formal business, the Audit Committee met on four occasions with the external auditors. On two occasions the Audit Committee
also held separate meetings with the external auditors at which no executive director or employee of the Company was present. In
relation to the appointment of external auditors and in order to safeguard auditor independence and objectivity, the Audit Committee has a policy of permitted services which details the services that can be provided by the Groups auditors and
those services which require specific advance approval by the Audit Committee. The policy also details services that the Groups auditors are not permitted to provide. For permitted services, the Audit Committee has delegated the determination
of fees to the Chief Financial Officer, provided the fee does not exceed £100,000. No services can be provided in excess of £100,000 without the prior approval of the Audit Committee. The policy was reviewed and revised in October 2009.
Both the existing policy and the policy in place prior to October 2009 were complied with throughout the year. The Audit Committee is
aware of and has approved the audit and non-audit services which have been provided during 2009 by the Companys external auditors, Deloitte LLP. Those non-audit services concerned advice on tax matters and transaction support in connection
with the SiRF acquisition which was considered to be appropriate, given their in-depth knowledge of the affairs and financial practices in the Group. The Audit Committee is satisfied that, notwithstanding this work, Deloitte LLP have retained
objectivity and independence during the year. The following table sets forth the fees paid by the Company to the external auditors as
approved by the Audit Committee.  2009

The line for Other Services for 2009 includes $316,000 for advisory work provided by Deloitte LLP in
connection with the acquisition of SiRF. The remaining balance for other services primarily consists of Deloitte LLP acting as UK reporting accountant and SEC regulatory reporting accountant. Deloitte LLP has been the Companys auditors since July 2002 and the cost, scope and effectiveness of the audit are reviewed regularly. The most
recent full review, including release of tenders to other possible audit firms was conducted in 2005. In 2009, the Chairman of the Audit Committee led a meeting which reviewed the effectiveness of the external auditors which concluded that Deloitte
LLP was performing satisfactorily and should be recommended for re-appointment at the Annual General Meeting. The Chairman of the Audit
Committee attends the Companys Annual General Meeting to respond to any shareholder questions that might be raised concerning the Audit Committees activities. Internal control Philosophy and policy The objective of the directors and senior management is to safeguard and increase the value of the
business and assets of the Company. Part of this objective requires the development of relevant policies and appropriate internal controls to ensure proper management of the Companys resources and the identification of risks which might serve
to undermine them. The Board is ultimately responsible for the Groups system of internal control and for reviewing its
effectiveness. The systems and processes established by the Board are designed to manage, rather than eliminate the risk of failure to achieve business objectives and provide reasonable, not absolute, assurance against misstatement or loss. The
Board has delegated responsibility for the review of practices and procedures to the Audit Committee. The Companys senior management, in conjunction with external advisers are responsible for undertaking periodic reviews of the suitability of
current systems on which they report to the Audit Committee. The Audit Committee reviews the findings to ensure the effectiveness and
efficiency of the processes

implemented by senior management. This includes discussions with senior management of the Group and consideration of reports that have been submitted. These findings are in turn regularly
reviewed and discussed by the full Board. The Board is satisfied that this process accords with the internal control guidance for directors set out in the Turnbull Report Internal Control: Guidance for Directors on the Combined Code and
that through its interface with management, the Board is aware of the major risks facing the Group and the steps taken by the Group to mitigate such risks, so far as is possible. The risk evaluation process has been the subject of review during 2009, and a revised process adopted which reflects the changing nature of the business. This ongoing review process included a
detailed assessment of the key risks affecting the Group prior to the acquisition of SiRF. The assessment was reported in detail in the Prospectus dated 24 June 2009 which was submitted to the UKLA as part of the completion of the acquisition
of SiRF and also within the Form F-4 filed with the US Securities and Exchange Commission on 29 May 2009 (as amended). Following completion of the acquisition of SiRF, the management of the combined organisation was engaged to complete a further
review of the key risks as part of the integration of the two entities. The findings from these reviews were considered by the Audit Committee. A risk evaluation process has been implemented throughout 2009 and was in place up to the date of
approval of this Annual Report and the financial statements. Following a recommendation by the Audit Committee, a meeting of the Board dedicated to the consideration of key risks of the Group was held in January 2010 in order to allow for detailed
discussion on issues of risk and risk management and to augment the process for approval of the Annual Report and financial statements. That meeting determined that the steps being taken by management were satisfactory. Managing risks The Board confirms that the actions it
considers necessary have been or are being taken to remedy such failings and weaknesses which it has determined to be significant from its review of the system of internal control. This has involved considering the matters reported to it and
developing plans and programmes that it considers are reasonable in the circumstances.


A summary of the structures and processes in place to identify and manage risks across the Group are
set out below. Risk profiling There is
an ongoing process to identify and evaluate risks faced by the Group, through the conduct of regular meetings by the Groups senior management, and engagement of external consultants where in the opinion of the Groups senior management
this is considered appropriate. Findings are reported to the Audit Committee together with recommended actions for managing the risks and a timetable for implementation. The assessment of prioritised risks is refreshed on a regular basis to reflect
changes to the business and any observations or proposals arising from events since the last review. A schedule of the prioritised risks is developed and reviewed by management to ensure that possible mitigation measures are considered and plans for
action agreed. Responsibility is assigned within the Group for carrying out proposed actions which are also reviewed and up-dated by management. Such a process of review was conducted in the months following the acquisition of SiRF. Controlling risk The Group has policies which address
a range of key business risks, including financial, treasury, health and safety and the protection of intellectual property. The policies are made available to relevant employees through policy manuals, an intranet site and also via employee
briefings on specific topics. Periodically, reviews are performed in order to verify that ongoing practices within relevant parts of
the Group comply with current policies. In addition, policies are themselves reviewed against best practice and in order to take appropriate account of developments both within or external to the Groups business operations. Steps are ongoing
to embed internal control and risk management further into the operations of the Group and to deal with areas of improvement which come to managements and to the Boards attention. As explained in the Directors Report  Business and Financial Review on pages 27 to 29, the Group has a treasury policy for the placement
of cash deposits with financial institutions. In September 2009, Ernst & Young LLP conducted an internal audit of the




CSR plc Annual Report
and Financial Statements 2009

Companys Treasury Policy and Procedures. The use of external advisers was considered appropriate given the increasing complexity of Treasury matters affecting the Company and to assist
management in a thorough understanding of the Treasury practices and policies within SiRF. The findings and recommendations from that audit were considered at the scheduled meeting of the Audit Committee held in October 2009 as part of its annual
review of the Treasury Policy. The review also considered amongst other aspects of the policy, the requirement for the Groups cash to be spread amongst multiple counter-parties and the minimum credit ratings required to be met to allow the
Group to make a deposit with each counter-party, in addition to the authorities required to manage the movement of funds. Reflecting a combination of management comments and the recommendations of the review, the Audit Committee considered a revised
Treasury Policy. This was subsequently submitted for adoption by the Board which occurred in October 2009. As one aspect of ensuring a
culture of integrity and encouraging high standards throughout the organisation, the Group has a formal whistle-blowing policy. The policy provides information on the process to follow in the event that any employee feels it appropriate to make a
disclosure where they believe there has been improper conduct or actions which could cause the companys good standing to be called into question. The policy was most recently up-dated during 2006. The Audit Committee ensures that employees are
reminded of the existence of the policy and of the Companys commitment to respond appropriately to circumstances warranting investigation. The Audit Committee is satisfied that the policy provides an adequate basis for employees to make
representations in confidence to the Group and for appropriate and proportionate investigation. During 2009, a Group-wide programme was
initiated providing for management to carry out self-assessments to determine ongoing compliance with Group policies and to report the findings. These reports are provided to the Internal Auditor who will provide interim reports between each
internal audit review. The intention of the process is to support management across the Group in better understanding how their teams are meeting Group standards and to encourage more timely corrective action where appropriate. In preparing for the
reviews,


support has been provided through the provision of self assessment forms and training on the conduct of the assessments. Monitoring and managing the status of residual risk The actions arising from external and internal
assessments of risks are consolidated and during 2009 the results were reported to the Audit Committee. The Audit Committee assesses
the findings and proposed actions for addressing residual risks and also advises on areas for further attention. Business continuity planning Since 2007 a rolling programme aimed at improving the Groups Business Continuity Plan has been in place. The project has been
facilitated by the risk management practice of a leading independent consultant. Through workshops and one-on-one interviews, the potential significant risks are identified and an action plan implemented to enable the Group to respond in the event
that such a risk arose. That plan was the subject of further work during 2009. This included a workshop attended by senior management conducted in November 2009 which assessed the adequacy of existing plans and provided feedback on areas for further
development across the Group. There is a programme of further reviews and testing due to take place during 2010. The findings and steps taken to date have been reported to the Audit Committee. Internal financial controls The Group has a
comprehensive system for regular monitoring and reporting of financial performance and assessing the adequacy of the Groups systems of internal controls. Risk assessment and evaluation is an integral part of the annual planning cycle. This
includes assessment of the Groups strategic direction, objectives and financial returns and the risks in achieving them. As part
of the planning cycle, a detailed budget is prepared by management and thereafter is reviewed and formally adopted by the Board. The budget and other targets are regularly updated via a rolling forecasting process and regular business review
meetings are also held involving senior management worldwide, at which the Groups overall performance

is assessed. The results of these reviews are reported to and discussed by the Audit Committee and the Board at each meeting. A summary of the key financial and non-financial risks inherent in
the Groups business is given on pages 45 to 57. These processes are supported by discrete reviews conducted by the Internal
Auditor and external advisers, as determined by the Audit Committee, in addition to the routine audits. The Board confirms that it has
reviewed the effectiveness of the system of internal controls which were in place throughout the financial year and up to the date of signing the Financial Statements for the 52 week period ended 1 January 2010. This Annual Report does not include a report of managements assessment regarding internal control over financial reporting or an attestation
report of the companys registered public accounting firm pursuant to US securities laws due to a transition period established by rules of the US Securities and Exchange Commission for companies who have recently filed an initial registration
statement with the US Securities and Exchange Commission. Disclosure controls and procedures The executive management, with the participation of the Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the
Groups disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the US Securities Exchange Act of 1934, as amended, or the Exchange Act) as of 1 January 2010. The Groups disclosure controls and
procedures are designed to ensure that the information which the Group is required to disclose in the reports that are filed or submitted under the Exchange Act is (i) recorded, processed, summarised and reported within the time periods
specified in the US Securities and Exchange Commissions rules and forms and (ii) accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as the principal executive and financial
officers, respectively, to allow timely decisions regarding required disclosures. Based on that evaluation, the Chief Executive Officer
and Chief Financial Officer concluded that the Groups disclosure controls and procedures were effective as of the end of the period covered by this report.

DIRECTORS REPORTDIRECTORS REMUNERATION REPORT

Directors report  Directors remuneration report




The Board presents the Remuneration Report for the 52 weeks ended 1 January 2010. Role of the Remuneration Committee The Board sets the Companys remuneration policy. The Remuneration Committee (the Committee) makes recommendations to the Board within its agreed terms of reference (available on
the Companys website www.csr.com or from the Company Secretary at the Companys registered office) on the Companys framework of executive remuneration and its cost. The Committee also determines on behalf of the Board, specific remuneration packages for each of the executive directors and for the Chairman. The Committee administers the Companys share
incentive plans for employees and monitors and provides guidance on the level and structure of remuneration for senior management who report to the Chief Executive Officer. The Board itself determines the remuneration of the non-executive directors.
No director plays a part in any discussion about their own remuneration. Mr Giacoletto-Roggio is Chairman of the Committee. The other
current members of the Committee, all of whom are independent non-executive directors within the definition of the Code, are set out on pages 59 and 60. Mr Mackintosh, Chairman of the Board, attends meetings of the Committee as a member. The
Company Secretary acts as secretary to the Committee. None of the members of the Committee has any personal financial interest (other than as shareholders), conflicts of interests arising from cross-directorships or day-to-day involvement in running
the business of the Company. An evaluation of the performance of the Committee was conducted during 2009, in regards to which more
information is contained in the Corporate Governance report on page 64. The Committee has access to detailed external research from
independent consultants. During the year, professional advice has been provided by Hewitt New Bridge Street (HNBS), Slaughter and May, Faegre and Benson LLP and Alithos Limited. Each of the advisers were appointed by the Committee. Slaughter and May
act as legal advisers to the


Company generally and Faegre and Benson also provide additional legal advice to the Company. Neither Hewitt New Bridge Street nor Alithos Limited provides other services to the Company. Terms of
engagement with each provider are available from the Company Secretary. The Committee determines policy for the remuneration of the
executive directors and is consulted and provides guidance on the broader remuneration policies for the Group below Board level based on recommendations of the Chief Executive Officer and the other executive directors. Further information on
meetings held and attendance by the members of the Committee is disclosed in the Corporate Governance report on page 72. The
Directors Report on Remuneration for the period ended 2 January 2009 was approved by the shareholders at the Annual General Meeting held in May 2009. As required by the Companies Act, shareholders will be invited to approve this report at
the Annual General Meeting to be held on 19 May 2010. This Report has been prepared in accordance with the Companies Act 2006
(the Act). The report also meets the relevant requirements of the Listing Rules of the Financial Services Authority and describes how the Board has applied the Principles of Good Governance relating to directors remuneration. The Act requires the auditors to report to the Companys members on certain parts of the Remuneration Report and to state whether
in their opinion those parts of the Remuneration Report have been properly prepared in accordance with the Act. The Remuneration Report has therefore been divided into separate sections for audited and unaudited information. In setting the remuneration policy, the Committee takes into account the strategic objectives of the Group and the expected performance of individual
directors within their areas of responsibility. Targets set in association with the performance related elements of pay take into account the strategic objectives of the Company for example in the development and release of particular chips, and the
development of strategic partnerships. These are

reviewed each year in the context of the plans set for the group as a whole and are agreed for each executive director at the start of a financial year. Unaudited information Changes in executive directors With effect from completion of the SiRF acquisition on 26 June 2009, Mr Kanwar Chadha
was appointed as an executive director to the Board and Chief Marketing Officer of CSR plc. Mr Chadha was a founder and an executive director of SiRF Technology Holdings Inc and served as Vice President of Strategic Corporate Initiatives, Corporate
Marketing and as Secretary at the time of the completion of the acquisition. Mr Chadhas biography and professional experience is set out on page 59. On 4 August 2009, Mr Chadha was granted options and share awards under the Companys Share Option and Share Award Plans of 400% of salary for share options and 200% of salary for share awards. These
exceptional awards were made as the Committee recognised the importance of retaining and motivating Mr Chadha following the acquisition and going forward. Each of the grants made under the Share Option and Share Award Plans are subject to satisfying
performance conditions. All of the options and shares granted to Mr Chadha are subject to a three year retention period and the requirement that, subject to certain mitigating factors, he is an employee at the end of the retention period. Remuneration policy for the executive directors Executive remuneration packages are designed in order to attract, motivate and retain employees of the highest calibre required by the Group in order to achieve its objectives, to meet the needs of customers and enhance value to
shareholders. There are five main elements of the remuneration package for executive directors and senior management, which include medium and long term incentives comprising basic annual salary, benefits-in-kind, the opportunity to participate in a
money purchase pension scheme, a cash bonus plan and participation in the Companys share incentive plans. The Companys
policy is that a substantial proportion of the remuneration of the executive directors should be performance-related. The payment of both cash bonuses and the vesting of share incentives are subject to meeting performance conditions


established by the Committee at the beginning of each performance period reflecting what, at that time, the Committee considers to be demanding targets. These targets are set taking appropriate
account of the challenging and rapidly evolving market in which the Group operates, and the expectations of the investment community on the Companys potential future performance. The Remuneration Committee considers corporate performance on environmental, social and governance issues and the extent to which these should be incorporated into the performance-related benefits
of individual directors. The Committee looked at the matter at the end of 2009 and determined that, given the Companys current activities and its strategic imperatives for 2010, it was not appropriate to incorporate such matters specifically
within the incentive arrangements for any executive director during 2010. This will be kept under review on an annual basis. Basic salary An executive directors basic salary is considered by the Committee on appointment and then reviewed each year and when an individual changes
position or responsibility. When making a determination as to the appropriate remuneration, the Committee considers remuneration practices within the Group as a whole and where considered relevant, conducts objective research on companies within the
Companys UK listed peers of a similar size with an international focus, reflecting that the Company is competing in a global market. The target salary is at mid-market (noting that after promotion or appointment to the Board it may take
several years to meet this policy), with the opportunity to go above this level, subject to sustained individual performance. With the
exception of Mr Ladas and Mr Chadha, both of whom are paid their salary in US Dollars, the executive directors in office at 1 January 2010 were paid in pounds sterling. Details of the basic salary of the executive directors who served during
the period ended 1 January 2010 are set forth in the table on page 82. As previously reported, salary levels were not adjusted at
1 January 2009 following the review conducted in December 2008. The Committees decision, which was supported by the Board as a whole, was

considered appropriate given the prevailing economic environment and the decision was in keeping with the general pay freeze which had been adopted for the Group. As stipulated in the 2008 report of the Committee to shareholders, the Committee kept under review whether any increases were warranted during the
year. In July 2009, following the completion of the acquisition of SiRF, the Committee reviewed the salary level of Mr van Beurden, the
Chief Executive Officer. The Committee assessed his overall performance since joining the Company and took into account the contribution he had made to facilitate the acquisition of SiRF, whilst also noting that his salary had remained unchanged
since his appointment in November 2007. The Committee consulted with and took advice provided by HNBS which highlighted that Mr van Beurdens salary was significantly below mid-market against a specific peer group and a general group of similar
sized companies. Having regard to these elements, the Committee concluded that Mr van Beurden should be awarded an increase in basic annual salary to £400,000 per annum which was effective from 1 July 2009. This increased salary
remains below the identified mid-market. As a result of this change in basic annual salary, the bonus potential for Mr van Beurden for
2009 was adjusted to ensure that the total potential cash remuneration before and after the basic salary increase was broadly comparable. This was achieved by reducing the maximum potential bonus from 150% to 100% of salary for Mr van Beurden
effective from 1 July 2009. Prior to 1 July 2009, Mr van Beurdens annual total potential cash remuneration would have been £750,000. Following the increase to Mr van Beurdens basic salary and the reduction of his maximum
potential bonus, the annual total potential cash remuneration became £775,000. Current salaries at February 2010 are:  J A J van Beurden

In keeping with a decision on the review of salaries for the Group as a whole, the salaries for the
executive directors were reviewed in February 2010, with any adjustment to take effect from 1 April 2010. The adjustment will be backdated to 1 January 2010 and the increase in salary for the first quarter will be paid in the March salary.
This adjustment is being carried out in 2010 only and applies to all employees. Benefits-in-kind The executive directors receive certain benefits-in-kind, comprising private medical insurance, life assurance of four times basic salary, and personal
accident insurance and subsistence expenses. During 2009, Mr Ladas, who lives in the US, was provided with support towards the cost of a UK temporary residence reflecting his frequent travel and stays in the United Kingdom as part of the performance
of his role. Mr Ladas and Mr Chadha also receive US-based dental plan insurance. Cash bonus plan The Committee is responsible for determining on what basis to incentivise employees, including executive directors, through a cash bonus plan. The
Committee establishes against defined targets the minimum threshold at which a bonus will be payable and the maximum potential award. In setting appropriate bonus thresholds and targets, the Committee may refer to the objective research on a
comparator group as noted on page 74 under Basic salary. The performance metrics used for the 2009 cash bonus comprised
underlying operating profit and cash generation in addition to personal performance objectives. These targets were set after considering the Companys budgeted underlying operating profit and market expectations on financial performance, in
addition to cash flow targets which recognised the significance of good cash management required in the challenging economic environment prevailing when the targets were established. The targets were agreed based upon objectives which were
considered to be appropriate and stretching against the background of the prevailing economic conditions. Achievement of targets based
on the Companys financial and strategic objectives and the personal performance of individual directors would result in determination by the Committee of the appropriate size of the bonus having regard to actual performance against the
targets. The maximum potential bonus

payable for the 52 weeks ended 1 January 2010 was 150% of salary for the period prior to 1 July 2009 and 100% of salary from 1 July 2009 for Mr van Beurden (adjusted for the reason explained
above) and 100% of salary for other executive directors. The on-target bonus potential for Mr van Beurden was 75% of salary for the period prior to 1 July 2009 and 50% of salary from 1 July 2009 and 50% of salary for other executive directors. The on-target financial objectives set at the beginning of the performance period were exceeded, which resulted in payment of bonus
being made in accordance with pre-determined hurdles. The extent to which these targets had been satisfied was initially considered by the audit committee and then discussed by the remuneration committee. In addition, the Committee also considered
the extent to which the personal objectives had been satisfied for each executive director in order to assess the amount which should be paid. Based on this assessment, the amount of the bonus paid to each executive director is as shown below.  J A J van Beurden

241,676 Following the decision of Mr Chadha to waive his entitlement to a cash bonus, the Committee determined to allot Mr Chadha 16,580 ordinary shares in the Company, in the form of restricted shares, which, subject to remaining an
employee as at 1 March 2011, will be transferred to Mr Chadha at that date. There are no further performance conditions applying to the transfer of the restricted shares and Mr Chadha may elect to hold or sell the shares on transfer at 1 March
2011. The Committee reviewed the bonus potential of the executive directors in February 2010 for the 2010 financial year. The cash
bonus potential was set at a maximum potential of 100% of salary. For each of Mr van Beurden and Mr Gardiner the bonus potential comprises a combined cash element up to a maximum potential of 100% of salary and a share element, which for Mr van
Beurden is a maximum opportunity of 120,000 shares and for Mr Gardiner is a maximum opportunity of 100,000. Both the cash and share elements are subject to satisfying financial,


strategic and personal objectives set by the Committee. The shares will, subject to meeting the performance conditions, vest in March 2011. Each of Mr van Beurden and Mr Gardiner may elect to
sell sufficient shares to satisfy the tax liability on vesting, but are otherwise required to hold the shares they receive for a further period of 12 months. Targets for the bonus plan for 2010 have been determined by taking into account the financial targets and strategic objectives of the Company, with due regard for market expectations in addition to personal objectives set
for each of the executive directors. All executive directors in office at 2 January 2010 have been invited to participate in the cash bonus plan for 2010. The use of a deferral period or potential clawback provisions in the cash bonus plan will be considered in due course along with other matters raised in the revised Combined Code. Share option plans The Company has a number of share
option plans intended to facilitate the motivation and retention of employees. Two of the plans were established prior to the Companys flotation, being the Founders Share Option Plan and the Global Share Option Plan. Whilst not all the awards
under these two plans have been exercised, the plans are closed for the purpose of any new awards, and neither plan was used during 2009 for grants to executive directors or to other employees. Following shareholder approval at the 2004 Annual General Meeting, the Company established the CSR plc Share Option Plan (CSOP). The
reason for the introduction of this plan was to provide a means by which to incentivise the executive directors and employees whilst aligning their interests more closely with those of the Companys shareholders. The Committee has
responsibility for supervising the CSOP and the grant of options in accordance with its rules. Awards are made to executive directors
and other employees at the discretion of the Committee. Awards for directors and other senior employees are subject to a three year retention period and the requirement that, subject to certain mitigating factors, the participant is an employee at
the end of the retention period.

In December 2009,
the Committee initiated a detailed review of the structure of the plans used by the Company to grant options to Directors and other employees. This review has been undertaken with due regard to the growth of the business and the increased relative
size of the Group outside of the UK following in particular the acquisition of SiRF in 2009. The review recognises the global nature of the Groups business and the need to attract retain and motivate employees at all levels of the Group who
can support the change in scale and spread of the business and support its objectives for further growth in the future. This process will involve consultation with shareholders during the course of 2010.

Since the introduction of the CSOP, through to and including grants made in 2008, the vesting of shares was subject to a performance target based on
the growth over a three year period in the Companys underlying earnings per share. Details of the targets for grants made in 2008 and prior years appear as notes to the table on page 85. The performance target for the 2007 grants were not met,
and these options therefore lapse.

As disclosed in the report of the Committee for 2008, following a review conducted in December 2008
by the Committee in conjunction with its adviser HNBS, of long term share reward structures, as applied across the Group from executive director level down, the Committee decided that the target for options under the CSOP would, for grants made in
2009, be based on relative Total Shareholder Return of the Company against a peer group over a period of three years. The peer group is shown below.

The Committee reviewed in February 2010 the grants of share options under the companys plans for each of the executive directors. The Committee looked in particular at the bonus arrangements for the CEO and CFO, and, taking
into consideration the exceptional performance of each over the period since they each joined the Company, and in particular during 2009, it was decided it was appropriate to make a higher grant under each plan at 200% of salary under the CSOP and
200% of salary under the Share Award Plan.

DIRECTORS REPORTDIRECTORS REMUNERATION REPORT continued






The Committee decided that the thresholds to be met would be as follows. None of the options shall
vest if the Companys relative position is below median. 30% of a grant shall vest at median, with full vesting of a grant for performance at the upper quartile. Shares shall vest on a straight-line basis between the median and upper quartile,
with no retesting of the performance condition if it is not met at the end of the three year period. The performance condition is
considered by the Committee to be challenging and appropriately aligned with shareholder interest to achieving sustained performance in the return to shareholders over the three year performance period. This same target has been adopted in respect
of grants to be made in 2010. The rules of the CSOP do not allow for options to be granted at a discount to the Companys share
price at the date of grant. The Companys policy is to grant options to executive directors at the discretion of the Committee up
to a maximum of 200% of salary, taking into account individual performance. Pursuant to the rules of the CSOP, the Committee also reserves to its discretion the right to grant awards at a higher proportion of basic salary which, in exceptional
circumstances only, such as recruitment of a new executive or key employee, could be up to 400% of basic salary. The Company operates
an HM Revenue and Customs approved SAYE Share Option Scheme for eligible employees under which options may be granted at a discount of up to 20% of market value. Executive directors resident in the UK are eligible to participate in the SAYE Share
Option Scheme. Following the acquisition of SiRF, and as approved by shareholders at the General Meeting held on 25 June 2009, the
Company introduced an Employee Share Purchase Plan (the ESPP) specifically for its US employees under which the option to acquire shares in the Company may be granted at a discount of up to 15% of the market value. US-based employees are
invited to participate in the ESPP during an offer period which is expected to be made once every twelve months. The ESPP allows US employees to save a pre-determined amount from their monthly salary which may at the end of a specified savings
period be used towards the purchase of shares in the Company. US resident directors may participate in the ESPP.


Performance share awards At the Annual General Meeting held in May 2005, shareholders approved the introduction of a Share Award Plan called the CSR Share Award Plan. Awards are made to executive directors and other employees at the discretion of
the Committee. Since the introduction of the Share Award Plan, vesting of the Share Awards made to executive directors and senior
management have been subject to Total Shareholder Return (TSR) over a fixed three year period with an additional requirement that the Company should have achieved a sustained improvement in underlying financial performance over the same
three year period. Grants of share awards below this level (which have been small in value) have been subject only to employment at the end of the retention period. With the decision to extend the grant of share awards with accompanying performance conditions to other employees, the Committee had decided that for grants in 2009, the performance condition for
vesting would be underlying earnings per share. The detail of the condition is that no Share Award will vest for a compound underlying
EPS growth of less than 7.5% per annum, adjusted for RPI. 30% vests for a compound underlying EPS growth of 7.5% per annum, adjusted for RPI and full vesting of the share awards occurs for a compound underlying EPS growth of 15% per
annum adjusted for RPI. Share awards vest on a straight line basis for a compound underlying EPS growth between 7.5% and 15% adjusted for RPI. There is no retesting of the performance condition if it is not met at the end of the three year
performance period. The Committee considers that these performance conditions are appropriate for the form of award and are suitably
stretching. Grants made in May 2005 completed the three year retention period in May 2008. Following completion of the three year
performance period (1 January 2005 to 31 December 2007) for these grants the Committee considered a report which had been prepared by an independent agency, Alithos Limited, on the Companys TSR performance. That report concluded that the
Companys comparative TSR performance against its peer group resulted in a ranking that allowed for 89.87% of the original grants to employees to vest.

The TSR performance target for the grants made in 2006 were not met and the Share Awards therefore lapse. The TSR performance target for
the grants made in 2007 were not met, and the Share Awards therefore lapse. The performance condition in respect of grants to be made
in 2010 is subject to meeting specific EPS targets in 2012. In order for 20% of the grant to vest, the Company must achieve an EPS of 58 cents, increasing to vesting at 100% for achieving an EPS of 70 cents. Above 58 cents up to maximum vesting at
70 cents, the shares will vest on a straight line basis. In accordance with the rules of the CSR Share Award Plan, the Committee will
reserve the right to grant awards at a proportion of basic salary normally up to a maximum of 100% of salary (200% in exceptional circumstances). The table below summarises awards granted and exercised in 2009 under the CSR Share Award Plan, and the total awards held by each executive director at 1 January 2010. No significant amendments are proposed to be made to the terms and conditions of any entitlement of an executive director under these share incentive
plans.


The level of award is considered each year in the light of performance. The Company monitors the awards of shares made under the various share plans which it operates in relation to their effect on dilution limits. Following shareholder approval at the 2005 Annual
General Meeting, the Company is able to make selective share awards while maintaining the traditional overall 10% limit on awards as a proportion of the issued share capital in any rolling ten year period. Conscious of the need to ensure that the satisfaction of issue of new shares to employees pursuant to its share schemes operates within ABI
guidelines, the CSR Employee Benefit Trust (the Trust) was established during 2007. The Trust will enable the grant of shares to employees on exercise of vested options to be met by using shares acquired by the Trust in the open market. During 2008, the Trust acquired in the open market an aggregate of 3,222,813 ordinary shares in CSR plc. This was satisfied through
cash drawn down under the terms of a Loan Facility Agreement established at the time of the creation of the Trust. During 2009 the Trust did not acquire any shares. The details of each purchase of ordinary shares in CSR plc and the total holding by
the Trust is shown in note 25 to the Consolidated Financial Statements on page 132.

the acquisition (see details of options on page 84).



Pension arrangements Three of the executive directors serving at the year end were members of the Cambridge Silicon Radio Retirement Benefits Scheme (the UK Pension Plan) which is an HM Revenue and Customs approved money purchase (defined
contribution) scheme operated for eligible employees in the United


Kingdom. One executive director has established their own personal pension plan to which the Company contributes. One director participates in the US 401K Plan which the Company operates for its
US-resident employees. Contributions are determined as a percentage of the employees gross basic salary. Details of the actual

contributions made by the Group to the UK Pension Plan and the US 401K Plan on behalf of the executive directors are set out in the table on page 83. Normal retirement age is 65 for employees and executive directors. Other than basic salary, no element of the directors remuneration is pensionable.


Share ownership Executive directors are encouraged to build up a shareholding in the Company to a level equivalent to 100% of their basic salary. This shareholding can be satisfied through retention of 50% (or more at the discretion of the director
concerned) of the shares obtained as a result of participating in a Company share plan, net of the shares sold to finance option exercises or to pay a National Insurance or income tax liability or overseas equivalent. The programme specifically
excludes the need for directors to make a personal investment should awards not vest. Normally the Committee would expect the executive director to achieve the holding within five years following appointment to the Board.

Directors contracts It is the
Companys policy that executive directors should have contracts of an indefinite term. As disclosed below executive directors have a service contract which is subject to one years notice from the Company. Each of Mr van Beurden, Mr
Collier, Mr Gardiner and Mr Ladas has a service agreement requiring them to give six months notice to the Company. The
details of the directors service contracts and notice period from the Company under their respective contracts for those in office at the year end are summarised in the table below:  Name of director

1 year In the event of termination, a director would be entitled to a payment not exceeding one years remuneration. In an appropriate case, the Company would have regard to the departing directors duty to mitigate against costs
to the Company. The contract with Mr Chadha remains to be finalised. Non-executive directors All non-executive directors have specific terms of engagement provided in
formal letters of appointment and their remuneration is determined by the Board within the limits set by the Articles of Association and based on independent surveys of fees paid to non-executive directors of similar companies. The fees for
non-executive directors are considered each year. The non-executive directors are appointed for a three year fixed term, subject to re-appointment by the shareholders. The letter of appointment of Mr Giacoletto-Roggio was due for renewal in January 2010. Following confirmation from Mr Giacoletto-Roggio that he was prepared to remain a director for a further three
year period, the Board determined at its meeting in December 2009 to re-appoint Mr Giacoletto-Roggio for a further three years effective from 4 January


2010. Mr Giacoletto-Roggio will be standing for re-election at the Annual General Meeting being held on 19 May 2010. The terms and conditions of appointment are available for inspection at the Companys registered office during normal business hours on request to the Company Secretary and up to 15 minutes
prior to and at the Companys Annual General Meeting. In May 2009 the Board reviewed the fees payable to non-executive directors
and determined that there should be no increase in the current arrangements. The basic fee for a non-executive director therefore remained £42,000. Following the retirement of Mr David Tucker from the Board immediately on the conclusion
of the Annual General Meeting held in May 2009, Mr Andrew Allner was appointed chairman of the Audit Committee and Mr Anthony Carlisle was appointed the Senior Independent Director. As a result, the fee paid to Mr Allner was increased by
£6,000 on a pro-rata basis and the fee paid to Mr Carlisle was increased by £5,500 on a pro-rata basis. The fee paid to Mr Giacoletto-Roggio, who acts as Chairman of the Remuneration Committee remained at £47,700. The fee paid
to Mr Mackintosh as Chairman of the Board remained £170,000. Fees are paid wholly in cash. The fees of the non-executive
directors and the Chairman were reviewed in February 2010. It was determined that the basic fee paid to non-executive directors would increase to £45,000. It was also agreed that the fee payable to Mr Carlisle in his capacity as Senior
Independent Director would be adjusted by the payment of a further £8,500 (previously £5,500), to Mr Allner in his capacity as chairman of the audit committee by payment of a further £9,000 (previously £6,000) and to
Mr Giacoletto-Roggio in his capacity as chairman of the remuneration committee £8,700 (previously £5,700). The fee payable to Mr Mackintosh, as Chairman of the Board was increased to £180,000. Non-executive directors do not receive any bonus, do not participate in awards under the Companys share schemes and are not eligible to join the
Companys pension scheme.

10th anniversary of the date of grant.

Note (vi): Shares granted under the
Share Award scheme in 2005, 2006, 2007 and 2008 vest after three years and have certain performance conditions attached. The shares vest in proportions from 30% to 100% dependent on the Companys TSR against a basket of comparator companies

reports of the Remuneration Committee subsequent to the determination of the Committee.

Note (vii): Options granted under the CSOP scheme in 2006 also

Company and its subsidiaries for the 52 week period ended 1 January 2010. Activities and business
review CSR is a leading developer and provider of single chip wireless solutions designed to support data and voice communications
between a wide range of products over short range radio links. More detailed information on the principal activities of CSR plc and its subsidiaries, together with a review of the businesses and a description of the principal risks and uncertainties
facing the Group along with other information that fulfils the requirements of the Business and Financial Review are set out on pages 8 to 44 and 45 to 57. Some information required by applicable US securities laws is set out in the section entitled

151. Financial results For a discussion of our financial results, please refer to the Directors Report  Business and Financial Review on pages 8 to 44. Our operating loss for 2009 was $15.9 million compared to a loss of $8.5 million in 2008 (2007: profit of $150.1 million). The underlying operating
profit for 2009 decreased to $26.9 million compared to $72.8 million in 2008 (2007: underlying operating profit of $181.3 million). Underlying operating profit is a non-GAAP measure; an explanation of our use of non-GAAP measures is given on page

with stated policy, explained on page 28, no dividend will be paid in respect of the 52 weeks ended 1 January 2010 (2008: nil). Future development It remains the Boards intention to develop the Group through
organic growth and selective acquisition.


Directors of the Board The directors who served during the year are detailed on page 62 of the Directors Report  Corporate Governance. Change of control All of the Companys share schemes contain provisions relating to a change of control of the Company following a takeover. Outstanding options and awards would, subject to satisfaction of applicable performance conditions and
certain rules of the particular schemes normally vest and become exercisable on a change of control (subject to a pro-rata adjustment reflecting the time elapsed since the month in which the grant was made). Share capital The Companys ordinary shares with a nominal value of 0.1p per share, are quoted on the London Stock Exchange. The rights and obligations attaching to the Companys ordinary shares are set out in the Companys
Articles of Association, copies of which can be obtained from Companies House in the UK or by writing to the Company Secretary. There are no restrictions on the voting rights attaching to the Companys ordinary shares. No person holds
securities in the Company carrying special rights with regard to control of the Company. The Company is not aware of any agreements between holders of securities that may result in restrictions on the transfer of securities or on voting rights.
Unless expressly stated to the contrary in the Articles of Association of the Company, the Companys Articles of Association may be amended by special resolution of the Companys shareholders. A summary of the Companys Articles of
Association are set out on pages 160 to 165. During the 52 weeks ended 1 January 2010, options were exercised pursuant to the
Companys share schemes. The number of shares allotted and the consideration received in respect of such allotments are detailed in note 24 of the Financial Statements beginning on page 128. ABI Guidelines relating to directors power to allot share capital and disapply pre-emption rights, are reflected in Resolution 10 (the
Section 551 Authority) and Resolution 11 respectively, in the Notice of Meeting.




CSR plc Annual Report
and Financial Statements 2009

The directors propose (Paragraph (A) of Resolution 10 in the Notice of Meeting) to renew the authority granted at the 2009 Annual
General Meeting to authorise the directors to allot equity or grant rights in respect of equity shares up to an aggregate nominal value of £61,029 (representing approximately one-third of the ordinary shares issued as at the latest practicable
date). In accordance with ABI Guidelines, the directors also propose (Paragraph (B) of Resolution 10 in the Notice of Meeting) to
renew the authority granted at the 2009 Annual General Meeting to authorise the directors to allot or grant rights in respect of equity shares representing two-thirds of the Companys issued share capital as at the latest practicable date (as
reduced by the nominal amount of any allotment or grant made under paragraph (A) of Resolution 10) in the case of a compensatory rights issue. This authority, if renewed, will represent in total an aggregate nominal value of £122,058.
This Section 551 Authority, if approved, will expire at the conclusion of the Annual General Meeting to be held in 2011 or 19 August 2011, whichever is the earlier. The limited power granted to the directors at the 2009 Annual General Meeting to allot equity shares for cash other than pro-rata to existing shareholders expires on the conclusion of this
years Annual General Meeting to be held on 19 May 2010. Subject to renewal of the Section 551 Authority, the directors recommend (Resolution 11 in the Notice of Meeting) that this authority also be renewed so as to give the directors the
ability (until the earlier of 19 August 2011, or the conclusion of the Annual General Meeting to be held in 2011) to issue equity shares for cash other than pro-rata to existing shareholders, in connection with a rights issue or up to a limit of 5%
of the ordinary shares issued at the 1 March 2010. The directors have no present intention to issue equity shares for cash other than pursuant to the Companys employee share schemes. The directors recommend that you vote in favour of Resolutions 10 and 11 to maintain the Companys flexibility in relation to future share
issues, including any issues to finance business opportunities should appropriate circumstances arise. A Special Resolution will be
proposed (Resolution 12 in the Notice of Meeting) to renew the directors


limited authority to repurchase ordinary shares in the market. This authority will be limited to a maximum of 18,308,724 ordinary shares (representing 10% of the Companys issued share
capital as at the latest practicable date) and also sets the minimum and maximum prices which may be paid. The directors believe it is
advantageous for the Company to have the flexibility to make market purchases of its own shares. In the event that shares are purchased, they would either be cancelled (and the number in issue would be reduced accordingly) or, subject to the
legislation referred to below, retained as treasury shares. The directors will only make purchases after consideration of the possible effect on earnings per share, the long term benefits to shareholders and consultation with advisers. The directors
have no present intention to purchase shares in the Company. The Companies (Acquisition of Own Shares) (Treasury Shares) Regulations
2003 allow shares repurchased by the Company to be held as treasury shares that may be cancelled, sold for cash or used for the purpose of employee share schemes. The Company currently holds no shares in treasury. The authority contained in the
Special Resolution will expire at the earlier of 19 August 2011, or the conclusion of the Annual General Meeting to be held in 2011. It is the current intention of the directors to renew this authority annually. New Articles of Association Following final implementation of the Companies Act 2006, and the coming into force of the Companies (Shareholders Rights) Regulations 2009, the directors are seeking approval for the adoption of new articles of association. The principal changes introduced in the new articles are summarised in the Appendix to the Notice of Annual General Meeting. Other
changes, which are of a minor, technical or clarifying nature and also some more minor changes which merely reflect changes made by the Companies Act 2006 or the Shareholders Rights Regulations, or conform the language of the new articles with
that used in the model articles for public companies produced by the Department for Business, Innovation and Skills have not been noted in the Appendix. The new articles showing all changes to the current articles are available for inspection, at
the Companys registered

office during normal working hours on a weekday (except Saturdays, Sundays and public holidays) until the Annual General Meeting and at the Annual General Meeting location from 15 minutes before
the Annual General Meeting until it ends. Notice required for shareholder meetings The Shareholders Rights Directive was implemented in the UK by the Companies (Shareholders Rights) Regulations 2009 on 3 August 2009. The
Regulations implementing this Directive increase the notice period for general meetings of the Company to 21 days, unless shareholders agree to a shorter notice period. On the basis of a resolution passed at the 2009 Annual General Meeting, the
Company is currently able to call general meetings (other than an annual general meeting) on 14 days notice and would like to preserve this ability. Resolution 14 seeks such approval. The approval will be effective until the Companys
next annual general meeting, when it is intended that a similar resolution will be proposed. In accordance with the Directive, the Company will offer an electronic voting facility for a general meeting called on 14 days notice. Employee Benefit Trust The CSR Employee Benefit Trust was established in 2007 to facilitate satisfying the issue of shares to employees within the Group on exercise of vested options under the various share option plans of the Company. During 2009, no ordinary shares in CSR plc were acquired by the Trust. The details of the purchases in prior years of ordinary shares in CSR plc is
shown in note 25 to the Financial Statements on page 132. The Trust holds a total of 4,689,580 ordinary shares in CSR plc representing 2.57% of the issued share capital at the date of this report. As participants in the share options plans, the executive directors of the Company are potential beneficiaries from the shares held by the Trust and
are therefore regarded for the purposes of the Companies Act as being interested in ordinary shares held by the Trust. Directors Details of the directors of the Board who served during the year are contained on page 62. Biographies of the
directors in office at 1 January 2010 are on pages 59 and 60.


Pursuant to the Companys Articles of Association a director shall retire from office and may
offer himself for re-appointment when they have been appointed since the last Annual General Meeting, held office in the preceding two annual general meetings and did not retire at either of them or has been in office for a continuous period of nine
years or more at the date of the meeting. In accordance with the Articles of Association, the directors retiring at the Annual General
Meeting will include Mr Kanwar Chadha, executive director and Chief Marketing Officer, and Mr Diosdado Banatao, a non-executive director, as they have been appointed since the last meeting. Being eligible, Mr Chadha and Mr Banatao offer themselves
for election. Mr Ron Mackintosh, non-executive director and Chairman of the Board, and Mr Sergio Giacoletto-Roggio, non-executive
director and Chairman of the Remuneration Committee, will also be retiring and, being eligible, offer themselves for re-appointment. The directors considered the performance of Mr Mackintosh and Mr Giacoletto-Roggio in connection with their
re-appointment and determined they had performed well. Accordingly, the Board supports Mr Mackintoshs and Mr Giacoletto-Roggios submission for re-appointment. The interests of the executive directors in the options of the Company are detailed in the Remuneration Report on page 84. Directors interests in shares The directors in office at 1 January 2010 and their families had the under-mentioned interests in the ordinary shares of the Company.  1 January2010

There were no changes to the directors shareholdings between 1 January 2010 and 9 February 2010. The foregoing holdings do
not include the ordinary shares held by the CSR Employee Benefit Trust in which the executive directors are potential beneficiaries as disclosed earlier. Conflicts of interests The Company has procedures in place to deal with conflicts of
interests and believes that procedures are operated efficiently. Payment of creditors The Group agrees payment terms with its suppliers when it enters into binding purchase contracts to ensure that suppliers are made aware of terms of
payment. The Company abides by these terms of payment. At 1 January 2010 the number of creditor days outstanding for the Company was 30 (2008: 30) and for the Group was 61 (2008: 64). Donations The Company and employees support a number of charities for a variety of causes. For the period ended 1 January 2010, the Company made charitable donations totalling $6,550 to charities local to the Groups operations. The
Company did not make any political donations during the year. Directors responsibility statement The directors are responsible for preparing the Annual Report and the financial statements in accordance with applicable law and
regulations. Company law requires the directors to prepare financial statements for each financial year. Under that law the directors
are required to prepare the Group financial statements in accordance with International Financial Reporting Standards (IFRSs) as adopted by the European Union and Article 4 of the IAS Regulation and have also chosen to prepare the Company financial
statements under IFRSs as adopted by the EU. The financial statements are also prepared in accordance with the IFRS as issued by the International Accounting Standards Board. Under company law the directors must not approve the accounts unless they
are satisfied that they give a true and fair view of the state of affairs of the company and of the profit or loss of the company for that period. In


preparing these financial statements, International Accounting Standard 1 requires that directors:  ·

properly select and apply accounting policies;  ·

present information, including accounting policies, in a manner that provides relevant, reliable, comparable and understandable information;  ·

provide additional disclosures when compliance with the specific requirements in IFRSs are insufficient to enable users to understand the impact
of particular transactions, other events and conditions on the entitys financial position and financial performance; and  ·

make an assessment of the companys ability to continue as a going concern. The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the companys transactions and
disclose with reasonable accuracy at any time the financial position of the company and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the company and
hence for taking reasonable steps for the prevention and detection of fraud and other irregularities. The directors are responsible for
the maintenance and integrity of the corporate and financial information included on the Companys website. Legislation in the United Kingdom governing the preparation and dissemination of financial statements may differ from legislation in
other jurisdictions. Each of the persons who is a director at the date of the approval of this report confirms that:  ·

so far as the director is aware, there is no relevant audit information of which the Companys auditors are unaware,  ·

the director has taken all the steps that he ought to have taken as a director to make himself aware of the relevant audit information and to
establish that the Companys auditors are aware of that information.

based on prudent market data, in their consideration of going concern. The Groups business activities, together with the factors
likely to affect its future development, performance and position are set out on pages 8 to 57. The financial position of the Group, its cash flows and liquidity position are described in the Business and Financial Review on pages 26 to 29. In
addition, note 33 to the Consolidated Financial Statements includes the Groups objectives, policies and processes for managing its capital; its financial risk management objectives; details of the financial instruments and hedging activities;
and its exposure to credit risk. The principal risks and uncertainties which could adversely impact the long term performance of the Group are discussed on pages 45 to 57 in the Business and Financial Review. All of these matters have been taken
into account by the directors in coming to their conclusions on going concern. Management is currently of the opinion that the Group
has adequate financial resources and a robust policy towards treasury risk and cash flow management. The directors believe that the Group is adequately placed to manage its business risks successfully despite the current uncertain economic outlook
and challenging macro economic conditions. After making enquiries, the directors have a reasonable expectation that the Company and the
Group have adequate resources to continue in operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis in preparing the Annual Report and Financial Statements. Auditors Deloitte LLP are the Companys auditors and have expressed their willingness to continue in the office of auditors and therefore, in accordance with Section 418 of the Companies Act 2006, a resolution for their
re-appointment will be proposed at the forthcoming Annual General Meeting. By Order of the Board Brett Gladden Company Secretary 9 February 2010

income, the consolidated and parent Company statement of changes in equity, and the related notes 1 to 49. The financial reporting framework that has been applied in their preparation is applicable law and International Financial Reporting Standards
(IFRSs) as adopted by the European Union and as regards the parent Company financial statements, as applied in accordance with the provisions of the Companies Act 2006.

This report is made solely to the Companys members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the
Companys members those matters we are required to state to them in an auditors report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company and
the Companys members as a body, for our audit work, for this report, or for the opinions we have formed.

Respective
responsibilities of directors and auditors

As explained more fully in the Directors Responsibilities Statement, the directors are responsible
for the preparation of the financial statements and for being satisfied that they give a true and fair view. Our responsibility is to audit the financial statements in accordance with applicable law and International Standards on Auditing (UK and
Ireland). Those standards require us to comply with the Auditing Practices Boards (APBs) Ethical Standards for Auditors.

Scope of the audit of the financial statements

An audit involves obtaining evidence about the amounts and disclosures in the
financial statements sufficient to give reasonable assurance that the financial statements are free from material misstatement, whether caused by fraud or error. This includes an assessment of: whether the accounting policies are appropriate to the
Groups and the parent Companys circumstances and have been consistently applied and adequately disclosed; the reasonableness of significant accounting estimates made by the directors; and the overall presentation of the financial
statements.

Opinion on financial statements

In our opinion:



| | · |  | the financial statements give a true and fair view of the state of the Groups and of the parent Companys affairs as at 1 January 2010 and of the
Groups loss for the 52 week period then ended;

4 of the IAS Regulation.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Separate opinion in relation to IFRSs as issued by the IASB

As explained in note 3 to the Group financial statements, the Group in addition to complying with its legal obligation to apply IFRSs as adopted by the European Union,
has also applied IFRSs as issued by the International Accounting Standards Board (IASB).

In our opinion the Group financial statements comply with
IFRSs as issued by the IASB.

Opinion on other matters prescribed by the Companies Act 2006

statements.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS



1. General Information

CSR plc is a company
incorporated in the United Kingdom under the Companies Act 2006. The address of the registered office is Churchill House, Cambridge Business Park, Cowley Road, Cambridge, CB4 0WZ, United Kingdom. The nature of the Groups operations and its
principal activities are set out in note 6.

These financial statements are presented in US dollars because that is the currency of the primary economic
environment in which the Group operates. Foreign operations are included in accordance with the policies set out in note 3.

Going concern

The financial statements have been prepared on the going concern basis. The directors have considered future cash forecasts and revenue projections,
based on prudent market data, in their consideration of going concern. The issues surrounding going concern are discussed regularly by the Board and were evaluated as part of the Groups budget for the next financial year and the Groups
longer term plans.

Note 33 includes the Groups objectives, policies and processes for managing its capital; its financial risk management
objectives; details of the financial instruments and hedging activities; and its exposure to credit risk. Management is currently of the opinion that the Group has adequate financial resources and a robust policy towards treasury risk and cash flow
management. The Group has $412.4 million of cash and cash equivalents, including treasury deposits and investments, as at 1 January 2010 and no debt liabilities. The directors believe that the Group is adequately placed to manage its business
risks successfully despite the current uncertain economic outlook and challenging macro economic conditions.

After making enquiries, the directors have
a reasonable expectation that the Company and the Group have adequate resources to continue in operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis in preparing the financial statements.

2. Adoption of New and Revised Standards

In the current financial period, the Group has adopted International Financial Reporting Standard 2 (amended) Share-based payment  vesting conditions and cancellations, International Accounting Standard 1
Presentation of Financial Statements (revised 2007), Amendments to International Financial Reporting Standard 7 Financial Instruments and both International Financial Reporting Standard 3 Business Combinations (as
revised in 2008) and International Accounting Standard 27 Consolidated and separate financial statements (as revised in 2008) in advance of their effective date.

The amendments to IFRS 2 require, amongst other things, the acceleration of share-based payment charges relating to employees who cease to contribute to a SAYE scheme. The application of this Standard has not
required a restatement of comparative periods.

The main change affecting CSR as a result of adopting IAS 1 (revised) requires the presentation of a
statement of changes in equity as a primary statement, separate from the income statement and statement of comprehensive income. As a result, a consolidated statement of changes in equity has been included as a primary statement, showing changes in
each component of equity for each period presented.

Due to the retrospective restatement of segments following the internal reorganisation outlined in
note 6, in line with IAS 1 (revised), CSR has presented an opening balance sheet position as at 28 December 2007 and the associated accompanying opening position in the notes to the financial statements. There is no impact on the opening
balance sheet position as a result of this restatement. A balance sheet as at 30 December 2006 has not been presented as the restatement of segment information had no impact on the balance sheet as at this date.

The impact of the early adoption of IFRS 3 (revised) and IAS 27 (revised) has resulted in some changes to the Groups accounting policies and in accordance with
the transitional provisions of IFRS 3(2008), that Standard has been applied prospectively to business combinations for which the acquisition date is on or after 3 January 2009:

The impact of IFRS 3(2008) Business Combinations has been:



| | · |  | to change the basis for allocating a portion of the purchase consideration in a business combination to replacement share-based payment awards granted at the
time of the combination;

| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The amendments to IFRS 7 expand the
disclosures required in respect of fair value measurements and liquidity risk.

Standards not affecting the reported results nor the financial
position:

The following new and revised Standards and Interpretations have been adopted in the current period. Their adoption has not had any
significant impact on the amounts reported in these financial statements but may impact the accounting for future transactions and arrangements.

periods will have no material impact on the financial statements of the Group.

3. Accounting Policies

Basis of Accounting

The financial statements
have been prepared in accordance with International Financial Reporting Standards (IFRSs) as issued by the International Accounting Standards Board (IASB) and as adopted by the European Union (EU).

The financial statements have been prepared on the historical cost basis, except for the revaluation of financial instruments. The principal accounting policies
adopted are set out below. The financial statements cover the 52 week period from 3 January 2009 to 1 January 2010; the comparatives are presented for the 53 week period from 29 December 2007 to 2 January 2009 and for the 52 week
period from 30 December 2006 to 28 December 2007. The financial statements are reported on a 52 or 53 week basis to be consistent with the Groups internal reporting.

Basis of Consolidation

The consolidated financial statements incorporate the financial statements of CSR plc
(the Company) and entities controlled by the Company (its subsidiaries, together the Group) drawn up to the dates indicated in the primary financial statements. Control is achieved where the Company has the power to govern the financial and
operating policies of an investee entity so as to obtain benefits from its activities.

The results of subsidiaries acquired or disposed of during the
year are included in the consolidated income statement from the effective date of acquisition or up to the effective date of disposal, as appropriate.

Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies used into line with those used by the Group.

All intra-Group transactions, balances, income and expenses are eliminated on consolidation.

Business
Combinations

Acquisitions of subsidiaries and businesses are accounted for using the acquisition method. The consideration for each acquisition is
measured at the aggregate of the fair values (at the date of exchange) of assets given, liabilities incurred or assumed, and equity instruments issued by the Group in exchange for the control of the acquiree. Acquisition-related costs are recognised
in the profit or loss as incurred for acquisitions that have occurred since the adoption of IFRS 3 (revised). Previous acquisitions have not been restated.

Where applicable, the consideration for the acquisition includes any asset or liability resulting from a contingent consideration arrangement, measured at its acquisition-date fair value. Subsequent changes in such fair values are adjusted
against cost of acquisition where they qualify as measurement period adjustments (see below). All other subsequent changes in the fair value of contingent consideration classified as an asset or liability are accounted for in accordance with
relevant IFRSs. Changes in the fair value of contingent consideration classified in equity are not recognised.

The acquirees identifiable assets,
liabilities and contingent liabilities that meet the conditions for recognition under IFRS 3 (2008) are recognised at their fair value at the acquisition date, except that:



| | · |  | Deferred tax assets and liabilities and liabilities or assets related to employee benefit arrangements are recognised and measured in accordance with IAS 12
Income taxes and IAS 19 Employee Benefits respectively;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · |  | Liabilities or equity instruments related to the replacement by the Group of an acquirees share-based payment awards are measured in accordance with IFRS 2
Share-based Payment;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · |  | Assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 Non-current Assets Held for Sale and Discontinued Operations
are measured in accordance with that Standard.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If the initial accounting for a business combination is incomplete by the end of the
reporting period in which the combination occurs, the Group reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period (see below), or additional assets or
liabilities are recognised to reflect new information obtained about facts and circumstances that existed as at the acquisition date that, if known, would have affected the amounts recognised as of that date.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS continued

3. Accounting Policies (continued)

Business Combinations (continued)



The measurement period is the period from the date of acquisition to the date the Group obtains complete information about facts and circumstances that existed as of
the acquisition date  and is subject to a maximum of one year.

The transition provisions given in IFRS 3 (2008) are such that the rules
governing the treatment of contingent consideration for pre-adoption business combinations do not change.

Where there are acquiree share-based payment
awards that will be exchanged for awards held by the Group, the fair value of the outstanding awards is allocated between consideration and post-combination service in accordance with IFRS 3 (revised 2008).

The Group recognises a contingent liability as of the acquisition date if there is a present obligation that arises from past events and its fair value can be
measured reliably in accordance with IFRS 3 (revised 2008).

Goodwill

Goodwill arising in a business combination is recognised as an asset at the date that control is acquired (the acquisition date). Goodwill is measured as the excess of the sum of the consideration transferred, the
amount of any non-controlling interest in the acquiree and the fair value of the Groups previously held equity interest (if any) in the entity over the net of the acquisition-date amounts of identifiable assets acquired and the liabilities
assumed.

If, after reassessment, the Groups interest in the fair value of the acquirees identifiable net assets exceeds the sum of the
consideration transferred, the amount of any non-controlling interest in the acquiree and the fair value of the Groups previously held equity interest (if any), the excess is recognised in profit or loss as a bargain purchase made.

For the purpose of impairment testing, goodwill is allocated to each of the Groups cash-generating units expected to benefit from the synergies of the
combination. Cash-generating units to which goodwill has been allocated are tested annually or more frequently when there is an indication that the unit may be impaired. To determine the recoverable amount of the cash-generating unit, the Group uses
discounted projected cash flows based on approved budgets and projections covering a period up to five years and estimates growth rates, terminal growth rates and discount rates specific to the economic environment within which the cash-generating
unit is operating. If the recoverable amount of the cash-generating unit is less than the carrying amount of the unit, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other
assets of the unit pro rata on the basis of the carrying amount of each asset in the unit. An impairment loss recognised for goodwill is not reversed in a subsequent period.

On disposal of a subsidiary the attributable amount of goodwill is included in the determination of the profit or loss on disposal.

Revenue Recognition

Revenue is recognised when it is probable that economic benefits will flow to the Group
and delivery has occurred or the service has been provided, the sales price is fixed or determinable, and collectibility is reasonably assured. These criteria are generally met at the time the product is shipped and delivered to the customer and,
depending on the delivery conditions, title and risk have passed to the customer and acceptance of the product, when contractually required, has been obtained, or, in cases where such acceptance is not contractually required, when management has
established that all aforementioned conditions for revenue recognition have been met and no further post-shipment obligations exist other than obligations under warranty. Examples of the above-mentioned delivery conditions are Free on Board
point of delivery and Costs, Insurance Paid point of delivery, where the point of delivery may be the shipping warehouse or any other point of destination as agreed in the contract with the customer and where title and risk in the
goods pass to the customer.

Revenues are recorded net of sales taxes, customer discounts, rebates and similar charges. For products for which a right
of return exists during a defined period, revenue recognition is determined based on the historical pattern of actual returns, or in cases where such information is lacking, revenue recognition is postponed until the return period has lapsed. Return
policies are typically based on customary return arrangements in local markets. Revenue is shown net of estimated provision for credit notes and returns.

A provision for product warranty is made at the time of revenue recognition and reflects the estimated costs of replacement and free of charge services that will be incurred by the Company with respect to the sold products.

3. Accounting Policies (continued)

Revenue Recognition (continued)



Royalty income, which is generally earned based upon a percentage of sales or a fixed amount per royalty earning product, is recognised upon shipment by the licencee.

Interest income is accrued on a time basis, by reference to the principal outstanding and at the effective interest rate applicable.

Leasing

Leases are classified as finance leases whenever the
terms of the lease transfer substantially all the risks and rewards of ownership to the lessee. All other leases are classified as operating leases.

Assets held under finance leases are recognised as assets of the Group at their fair value or, if lower, at the present value of the minimum lease payments, each determined at the inception of the lease. The corresponding liability to the
lessor is included in the balance sheet as a finance lease obligation. Lease payments are apportioned between finance charges and reduction of the lease obligation so as to achieve a constant rate of interest on the remaining balance of the
liability. Finance charges are charged directly to the income statement.

Rentals payable under operating leases are charged to the income statement on
a straight-line basis over the term of the relevant lease.

Benefits received and receivable as an incentive to enter into an operating lease are also
spread on a straight line basis over the lease term.

Foreign Currencies

The functional currency of CSR plc is the US dollar and this is also the presentation currency for the consolidated financial statements. Transactions in currencies other than US dollars are recorded at the rates
of exchange prevailing on the dates of the transactions. At each balance sheet date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the balance sheet date. Non-monetary assets
and liabilities carried at fair value that are denominated in foreign currencies are translated at the rates prevailing at the date when the fair value was determined. Gains and losses arising on retranslation are included in the net profit or loss
for the period except for exchange differences on transactions entered into to hedge certain foreign currency risks (see policy on Hedge Accounting).

In order to hedge its exposure to certain foreign exchange risks, the Group enters into forward contracts (see Financial Instruments policy for details of the Groups accounting policies in respect of such derivative financial
instruments).

On consolidation, the assets and liabilities of the Groups overseas operations are translated at exchange rates prevailing on the
balance sheet date. Income and expense items are translated at the average exchange rates for the period. Currency translation differences are recognised directly in equity.

Operating (Loss) Profit

Operating (loss) profit is stated before investment income and finance costs.

The income statement has been presented with certain items split out as separate line items. Management believes that this presentation aids the
understanding of the Groups financial performance and this presentation is used for internal performance evaluation. Items that have been split out on the face of the income statement are the amortisation of acquired intangible assets,
share-based payment charges under IFRS 2, charges associated with integration and restructuring, acquisition fees, in 2008 and 2007 the deferred tax adjustment to goodwill, in 2008 the asset impairment and in 2007, the patent dispute settlement.

Retirement Benefit Costs

Payments to defined
contribution retirement benefit schemes are charged as an expense as they fall due. Differences between contributions payable in the period and contributions actually paid are shown as either accruals or prepayments in the balance sheet.

Taxation

The tax expense represents the sum of the current
tax expense and the deferred tax expense for the period.

3. Accounting Policies (continued)

Taxation (continued)



The tax payable is based on taxable (loss) profit for the period. Taxable profit differs from net profit as reported in the income statement because it excludes items
of income and expense that are taxable or deductible in other periods and it further excludes items that are never taxable or deductible. The Groups liability for current tax is calculated using tax rates that have been enacted or
substantively enacted by the balance sheet date.

Deferred tax is the tax expected to be payable or recoverable on differences between the carrying
amounts of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit, and is accounted for using the balance sheet liability method. Deferred tax liabilities are generally recognised
for all taxable temporary differences and deferred tax assets are recognised to the extent that it is probable that taxable profits will be available against which deductible temporary differences, unused carried forward tax losses and unused
carried forward tax credits can be utilised. However, such assets and liabilities are not recognised if the temporary differences arise from:



| | · |  | the initial recognition of goodwill;
| | - |  | ------------------------------------



| | · |  | the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the taxable profit nor the
accounting profit;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · |  | investments in subsidiaries and associates, and interests in joint ventures, where the Group is able to control the reversal of the temporary difference and it
is probable that the temporary difference will not reverse in the foreseeable future.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The carrying amount of deferred tax assets is
reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered.

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. Deferred tax is charged
or credited in the income statement, except when it relates to items charged or credited directly to equity, in which case deferred tax is also dealt with in equity.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same
taxation authority and the Group intends to settle its current tax assets and liabilities on a net basis.

Judgement is required when determining the
provision for taxes as the tax treatment of some transactions cannot be finally determined until a formal resolution has been reached with the tax authorities. Tax benefits are not recognised unless it is probable that the benefit will be obtained.
Tax provisions are made if it is probable that a liability will arise and the liability can be reliably measured. The Group reviews each significant tax liability or benefit to assess the appropriate accounting treatment.

Government grants, by means of tax relief for research and development expenditure, are recognised as income as qualifying expenditures are made.

Property, Plant and Equipment

Property, plant and equipment
are stated at cost less accumulated depreciation and any recognised impairment loss.

Depreciation is charged so as to write off the cost of the assets,
less estimated residual value, over their estimated useful lives, using the straight line method, on the following basis:



|                       |  |                      |  | 
|---------------------- |  | -------------------- |  |

|Test equipment         |  | 2 to 5 years         |  | 
|                       |  |                     
|Office equipment       |  | 3 years              |  | 
|                       |  |                     
|Furniture and fittings |  | 5 years              |  | 
|                       |  |                     
|Leasehold improvements |  | Minimum lease period |  |

Residual values are the estimated amount that the Group would obtain from disposal of the asset, after deducting estimated costs of disposal, if the asset were already
of the age and in the condition expected at the end of its useful life, based on prices prevailing at the balance sheet date.

In general residual
values are zero or negligible, due to the technical and specialised nature of assets held. Residual values are reviewed annually.

Assets held under
finance leases are depreciated over their expected useful lives on the same basis as owned assets or, where shorter, over the term of the relevant lease.

The gain or loss arising on the disposal or retirement of an asset is determined as the difference between the sales proceeds and the carrying amount of the asset and is recognised in the income statement.

Assets in the course of construction are carried at cost less any recognised impairment losses. Costs included are those that directly relate to the construction of
the asset. Depreciation of these assets commences when the assets are ready for their intended use.

Other Intangible Assets

Other intangible fixed assets are stated at cost or fair value for items acquired in business combinations, net of amortisation and any provision for impairment. No
amortisation is provided on assets in the course of construction. On other intangible fixed assets, amortisation is provided at rates calculated to write off the cost or fair value, less estimated residual value, of each asset on a straight line
basis over its expected useful life as follows:



|                                     |  |               |  | 
|------------------------------------ |  | ------------- |  |

Assets in the course of construction are carried at cost net of any provision for
impairment. Costs included are those that directly relate to the construction or production of the asset. Amortisation of these assets commences when the assets are ready for their intended use.

Research and Development Expenditure

Expenditure on research
activities is recognised as an expense in the period in which it is incurred.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS continued

3. Accounting Policies (continued)

Research and Development Expenditure (continued)



An internally generated intangible asset arising from the Groups product development is recognised only if all of the following conditions are met:



| | · |  | an asset is created that can be identified (such as a new device or software);
| | - |  | ------------------------------------------------------------------------------



| | · |  | the project from which the asset arises meets the Groups criteria for assessing technical feasibility;
| | - |  | -------------------------------------------------------------------------------------------------------



| | · |  | it is probable that the asset created will generate future economic benefits; and
| | - |  | ---------------------------------------------------------------------------------



| | · |  | the development cost of the asset can be measured reliably.
| | - |  | -----------------------------------------------------------

Internally generated intangible assets are amortised on a straight line basis over their useful lives. Where no internally generated intangible asset can be recognised, development expenditure is recognised as an
expense in the period in which it is incurred.

Impairment of Tangible and Intangible Assets Excluding Goodwill

At each balance sheet date, the Group reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets
have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where the asset does not generate cash flows that are independent
from other assets, the Group estimates the recoverable amount of the cash-generating unit to which the asset belongs. An intangible asset with an indefinite useful life is tested for impairment annually and whenever there is an indication that the
asset may be impaired.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated
future cash flows are discounted to their present values using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been
adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the
asset (cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised as an expense immediately. After the recognition of an impairment loss, any depreciation or amortisation charge for the asset is adjusted for future
periods to allocate the assets revised carrying value, less estimated residual value, on a systematic basis, over its remaining useful life.

Where an impairment loss subsequently reverses, the carrying amount of the asset (cash-generating unit) is increased to the revised estimate of its recoverable amount, but the reversal is limited so that the increased carrying amount does
not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (cash-generating unit) in prior years. A reversal of an impairment loss is recognised as income immediately.

Inventories

Inventories are stated at the lower of cost and
net realisable value. Cost comprises direct materials and, where applicable, those overheads that have been incurred in bringing the inventories to their present location and condition. Cost is calculated using the first-in-first-out (FIFO) method.
Net realisable value represents the estimated selling price less all estimated costs of completion and costs to be incurred in marketing, selling and distribution.

Financial Instruments

Financial assets and financial liabilities are recognised on the Groups balance
sheet when the Group becomes a party to the contractual provisions of the instrument.

Loans and Receivables

Trade receivables, loans and other receivables that have fixed or determinable payments that are not quoted in an active market are classified as loans and
receivables. Loans and receivables are measured at amortised cost using the effective interest method, less any impairment or appropriate allowances for estimated irrecoverable amounts. Interest income is recognised by applying the effective
interest rate, except for short-term receivables when the recognition of interest would be immaterial.



CSR plc Annual Report and Financial Statements 2009

Financial Instruments (continued)



Treasury deposits and investments

Treasury deposits and
investments are recognised and derecognised on a trade date where a purchase or sale of an investment is under a contract whose terms require delivery of the investment within the timeframe established by the market concerned, and are initially
measured at cost, including transaction costs.

Treasury deposits and investments consist of money market deposits in USD, GBP and obligations of the
United States government treasury with original maturities of over ninety days. Interest income is recorded as it accrues over the period of the investment at rates fixed at the time of inception.

Cash and Cash Equivalents

Cash and cash equivalents comprise
cash on hand and demand deposits and other short-term highly liquid investments that are readily available convertible to a known amount of cash and are subject to an insignificant risk of changes in value.

Financial Assets at FVTPL (Fair Value Through Profit and Loss)

Financial Assets are classified as FVTPL where the asset liability has been designated as FVTPL.

A financial asset may be designated as FVTPL
upon initial recognition if:



| | · |  | Such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| | · |  | The financial asset forms part of a group of financial assets or financial liabilities or both, which is managed and its performance evaluated on a fair value
basis, in accordance with the Groups documented risk management or investment strategy, and information about the Group is provided internally on that basis; or
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · |  | It forms part of a contract containing one or more embedded derivatives, and IAS 39 Financial Instruments: Recognition and Measurement permits the entire
combined contract (asset or liability) to be designated FVTPL.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Financial assets at FVTPL are stated at fair value, with any resultant
gain or loss recognised in profit or loss. Fair value is determined in the manner described in note 33.

Derecognition of Financial Assets

The Group derecognises a financial asset only when the contractual rights to the cash flows from the asset expire; or it transfers the financial
asset and substantially all the risks and rewards of ownership of the asset to another entity. If the Group neither transfers nor retains substantially all the risks and rewards of ownership and continues to control the transferred asset, the Group
recognises its retained interest in the asset and an associated liability for amounts it may have to pay.

Impairment of Financial Assets

Financial assets are assessed for indicators of impairment at each balance sheet date. Financial assets are impaired when there is objective
evidence that, as a result of one or more events that have occurred after the initial recognition of the asset, the estimated future cash flows of the investment have been impaired. Objective evidence of impairment could include significant
financial difficulty of the issuer or the counterparty; or default or delinquency in interest or principal payments; or it becoming probable that the borrower will enter bankruptcy or financial re-organisation.

The carrying amount of the financial asset is reduced by the impairment loss directly for all financial assets with the exception of trade receivables where the
carrying amount is reduced through the use of an allowance account. When a trade receivable is considered uncollectible, it is written off against the allowance account.

Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognised in profit or loss.

Financial Liabilities and Equity

Financial liabilities and
equity instruments are classified according to the substance of the contractual arrangements entered into.

Financial Instruments (continued)



Trade Payables

Trade payables are not interest bearing and are
initially measured at fair value, net of transaction cost.

Subsequently these are measured at amortised cost using the effective interest method, with
interest recognised on an effective yield basis.

Equity Instruments

An equity instrument is any contract that evidences a residual interest in the assets of the Group after deducting all of its liabilities. Equity instruments issued by the Group are recorded at the proceeds
received, net of direct issue costs.

Financial Liabilities at FVTPL (Fair Value Through Profit and Loss)

Financial liabilities are classified as FVTPL where the financial liability has been designated as FVTPL.

A financial liability may be designated as FVTPL upon initial recognition if:



| | · |  | Such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------



| | · |  | The financial liability forms part of a group of financial assets or financial liabilities or both, which is managed and its performance evaluated on a fair
value basis, in accordance with the Groups documented risk management or investment strategy, and information about the Group is provided internally on that basis; or
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · |  | It forms part of a contract containing one or more embedded derivatives, and IAS 39 Financial Instruments: Recognition and Measurement permits the entire
combined contract (asset or liability) to be designated FVTPL.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Financial liabilities at FVTPL are stated at fair value, with any
resultant gain or loss recognised in profit or loss.

Derecognition of Financial Liabilities

The Group derecognises financial liabilities when, and only when, the Groups obligations are discharged, cancelled or they expire.

Derivative Financial Instruments

The Groups activities
expose it primarily to the financial risks of changes in foreign currency exchange rates. The Group uses foreign exchange forward contracts to hedge these exposures. The Group does not use derivative financial instruments for speculative purposes.
Further details of derivative financial instruments are disclosed in note 33 to the financial statements.

The use of financial derivatives is governed
by the Groups policies approved by the Board of directors, which provides written principles on the use of financial derivatives. The Groups policy is to hedge between 75% and 90% of forecast GBP expenditure for the following 11 to 15
months.

Derivative financial instruments are initially recorded at fair value at the date a derivative contract is entered into and are subsequently
remeasured to fair value at each balance sheet date. The resulting gain or loss is recognised in profit or loss immediately unless the derivative is designated and effective as a hedging instrument, in which event the timing of the recognition in
profit or loss depends on the nature of the hedge relationship.

Hedge Accounting

Hedges of foreign exchange risk on firm commitments are accounted for as cash flow hedges.

At the inception of the
hedge relationship, the Group documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the
hedge and on an ongoing basis, the Group documents whether the hedging instrument that is used in a hedging relationship is highly effective in offsetting changes in cash flows of the hedged item.

Note 18 sets out details of the fair values of the derivative instruments used for hedging purposes.



CSR plc Annual Report and Financial Statements 2009

3. Accounting Policies (continued)

Financial Instruments (continued)



Movements in the hedging reserve in equity are also detailed in the statement of changes in equity.

Cash Flow Hedges

The effective portion of changes in the fair value of derivatives that are designated and
qualify as cash flow hedges are deferred in equity. The gain or loss relating to the ineffective portion is recognised immediately in profit or loss.

Amounts deferred in equity are recycled into profit or loss in the periods when the hedged item is recognised in profit or loss. When the forecast transaction that is hedged results in the recognition of a non-financial asset or a
non-financial liability, the gains and losses previously deferred in equity are transferred from equity and included in the initial measurement of the cost of the asset or liability.

Hedge accounting is discontinued when the Group revokes the hedging relationship, the hedging instrument expires or is sold, terminated, exercised or no longer qualifies for hedge accounting. Any cumulative gain or
loss deferred in equity at that time remains in equity and is recognised when the forecast transaction is ultimately recognised in profit or loss. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was
deferred in equity is recognised immediately in profit or loss.

Provisions

Provisions for warranty and returns costs are recognised at the date of sale of the relevant products, at the directors best estimate of the expenditure required to settle the Groups liability.

Provision is made for onerous contracts at the fair value of the minimum unavoidable payments, net of any amounts recoverable. Where amounts are known
and timings certain, onerous amounts are accrued instead.

Share-Based Payment

The Group has applied the requirements of IFRS 2 Share-based Payment. In accordance with the transitional provisions, IFRS 2 has been applied to all grants of equity instruments after 7 November 2002 that
were unvested as of 1 January 2005.

The Group issues equity-settled share-based payments to certain employees, including share options with
non-market based vesting conditions. Equity settled share-based payments are measured at the fair value at the date of grant. The fair value determined at the grant date of the equity-settled share-based payments is expensed on a straight-line basis
over the vesting period, based on the Groups estimate of shares that will eventually vest.

For grants where options vest in instalments over the
vesting period, each instalment is treated as a separate grant, which results in fair value of each instalment being spread across the vesting period of that instalment.

Fair value is measured by use of a Black-Scholes model for most of share options in issue. The expected life used in the model has been adjusted, based on managements best estimate, for the effects of
non-transferability, exercise restrictions, and behavioural considerations.

For certain share options which include TSR related condition the fair
value is estimated through the use of a Monte-Carlo simulation.

For a business combination where there are acquiree share-based payment awards that
will be exchanged for awards held by the Group, the fair value of the outstanding awards is allocated between consideration and post-combination service in accordance with IFRS 3 (revised 2008) using the valuation techniques described in IFRS 2. The
allocation of the fair value of the options outstanding to consideration results in a credit to equity in the share-based payment reserve.

Employee
Benefit Trust

The Group has established an employee benefit trust which is a separately administered trust and is funded by loans from Group
companies. The assets of the trust comprise shares in CSR plc and cash balances. The Group recognises assets and liabilities of the trust in the consolidated accounts and shares held by the trust are recorded at cost as a deduction from
shareholders equity.

Contingent liabilities

A contingent liability may arise where there is possible obligation that arises from past events, whose occurrence or non-occurrence will only be confirmed by
uncertain future events or where a present obligation arises from past events but where an outflow of resources from the Group is not probable and/or the amount of the obligation cannot be reliably measured. The Group recognises liabilities where
there is a present obligation and an outflow of resources from the Group is probable and can be reliably measured.

4. Critical
Accounting Judgements and Key Sources of Estimation and Uncertainty

These consolidated financial statements have been prepared in accordance with
IFRS as issued by the IASB and as adopted by the European Union (EU).

The preparation of financial statements requires the directors to make estimates
and assumptions about future events that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities.

Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgement based on various assumptions and other factors such as historical experience, current
and expected economic conditions. The directors constantly re-evaluate these significant factors and make adjustments where facts and circumstances dictate. The directors believe that the following accounting policies are critical due to the degree
of estimation required and / or the potential material impact they may have on the Groups financial position and performance.

Inventory
Valuation

Inventories are stated at the lower of cost and net realisable value. Provisions for excess or obsolete inventory are recorded based upon
assumptions about future demand and market conditions.

The level of inventory provisioning required is sensitive to changes in the forecast sales of
particular products which is dependent on changes in conditions in the Groups markets. If changes in actual market conditions are less favourable than those projected, additional inventory provisions may be required; similarly if changes in
actual market conditions are more favourable than predicted, the Group may be able to release a proportion of the inventory provision.

Business
Combinations and Goodwill Impairments

The amount of goodwill initially recognised as a result of a business combination is dependent on the
allocation of the purchase price to the fair value of the identifiable assets acquired and the contingent liabilities assumed. The Group uses judgement, estimates and involves external specialists in determining the fair value of identifiable assets
and liabilities acquired in a business combination, as well as calculating the fair value of the purchase consideration on acquisition.

Allocation of
the purchase price affects the results of the Group as finite lived intangible assets are amortised, whereas indefinite lived intangible assets, including goodwill, are not amortised and could result in differing amortisation charges based on the
allocation to indefinite lived and finite lived intangible assets.

The Group assesses the carrying value of identifiable intangible assets, long-lived
assets and goodwill annually, or more frequently if events or changes in circumstances indicate that such carrying value may not be recoverable. Factors considered important, which could trigger an impairment review, include the following:



| | · |  | significant under performance relative to historical or projected future results;
| | - |  | ---------------------------------------------------------------------------------



| | · |  | significant changes in the manner of our use of the acquired assets or the strategy for our overall business; and
| | - |  | -----------------------------------------------------------------------------------------------------------------



| | · |  | significantly negative industry or economic trends.
| | - |  | ---------------------------------------------------

This assessment is based upon projections of anticipated discounted future cash flows. The most significant variables in determining cash flows are future growth in sales, discount rates, terminal values, the number of years on which to
base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows.

The Group determines discount
rates to be used based on the risk inherent in the related activitys current business model and industry comparisons. Terminal values are based on the expected life of products and forecasted life cycle and forecasted cash flows over that
period. While the Group believes that its assumptions are appropriate, such amounts estimated could differ materially from what will actually occur in the future. In assessing goodwill, these discounted cash flows are prepared at a cash-generating
unit level.

Business Combinations and Goodwill Impairments (continued)



Note 13 to the financial statements provides further disclosures on the assumptions underlying the impairment review and the allocation
of goodwill by reportable segments.

Provisions for Returns and Warranty Claims

The Group provides for the estimated cost of returns and product warranties at the time revenue is recognised. The Groups products are covered by product warranty plans of varying periods, depending on local
practices and regulations. While the Group engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers, our warranty obligations are affected by actual product
failure rates (field failure rates) and by material usage and service delivery costs incurred in correcting a product failure.

The Groups
warranty provision is established based upon its best estimates of the amounts necessary to settle future and existing claims on products sold as of the balance sheet date. As the Group continuously introduces new products which incorporate complex
technology, and as local laws, regulations and practices may change, it will be increasingly difficult to anticipate our failure rates, the length of warranty periods and repair costs. While the Group believes that its warranty provisions are
adequate and that the judgements applied are appropriate, the ultimate cost of product warranty could differ materially from our estimates. When the actual warranty cost of our products is lower than we originally anticipated, the Group releases an
appropriate proportion of the provision, and if the warranty cost is higher than anticipated, the Group increases the provision.

Accounting for
Share-based Payments

The Group applies IFRS 2 Share-based payments in relation to the accounting for share-based payments in respect of
options and share awards granted after 7 November 2002 and which had not vested as at 1 January 2005.

Under IFRS 2, the share-based
compensation is measured at the grant date, based on the estimated fair value of the award, and is recognised as an expense over the employees requisite service period.

The fair value of most of the options granted is measured by use of a Black-Scholes model, taking into account the terms and conditions upon which the options were granted. The expected life used in the model has
been adjusted, based on managements best estimate for the effects of non-transferability, exercise restrictions and, behavioural considerations. The volatility used in the model is based on movements in the Groups share price for a
period matching that of the vesting period of the options. The risk-free interest rate used is the implied yield currently available on zero-coupon government issues in the UK, with a remaining term equal to the expected term of the option being
valued (based on the options remaining contractual life and taking into account the effects of expected early exercise). For certain share awards which include total shareholder return related conditions, the fair value is estimated through
the use of a Monte-Carlo simulation.

The amount recognised as an expense is adjusted to reflect the actual number of shares that vest.

Non-market vesting conditions are included in assumptions about the number of shares that are expected to become exercisable. The estimates of the number of share
options and awards that are expected to become exercisable are reviewed at each balance sheet date. The impact of the revision of original estimates, if any, is recognised in the income statement and a corresponding adjustment to equity. Note 31 to
the Consolidated Financial Statements provides details on the valuation assumptions made for each grant of share options and awards during the period.

Share Options and Taxation

In the UK and US the Group is entitled to a tax deduction for amounts treated as compensation on exercise of
certain employees share options under each jurisdictions tax rules. This gives rise to a temporary difference between the accounting and tax bases and hence a deferred tax asset is recorded. This asset is calculated by comparing the
estimated amount of tax deduction to be obtained in the future (based on the share price at the balance sheet date) with the share-based payment expense recorded in the income statement. If the amount of estimated future tax deduction exceeds the
cumulative amount of share-based payment expense at the statutory rate, the excess is recorded directly in equity, against retained earnings.

No
share-based payment expense is recorded in respect of options granted before 7 November 2002. Nevertheless, tax deductions have arisen and will continue to arise on these options. The tax effects in relation to these options are recorded
directly in equity against retained earnings.

4. Critical Accounting Judgements and Key Sources
of Estimation and Uncertainty (continued)



Revenue recognition

Sales are recognised when the significant risks and rewards of ownership have transferred to the buyer, continuing managerial involvement usually
associated with ownership and effective control have ceased, the amount of revenue can be measured reliably, it is probable that economic benefits associated with the transaction will flow to the Group and the costs incurred or to be incurred in
respect of the transaction can be measured reliably.

This requires the Group to assess at the point of delivery whether these criteria have been met.
When the Group determines that such criteria have been met, revenue is recognised. The Group records estimated reductions to revenue for pricing agreements, price protection, other volume based rebates and expected returns. Estimated sales
adjustments for volume based discount programs are based largely on shipment information.

Income Taxes

The Group is subject to the income tax laws of the various tax jurisdictions in which we operate, principally the United Kingdom. These laws are complex and subject to
different interpretations by taxpayers and tax authorities. When establishing income tax provisions, we therefore make a number of judgments and interpretations about the application and interaction of these laws. Changes in these tax laws or our
interpretations of these laws and the resolution of future tax audits could significantly impact our effective tax rate and the results of operations in a given period.

The Group estimates its income taxes in each of the jurisdictions in which it operates. This process involves estimating its current tax liability together with assessing temporary differences resulting from
differing treatment of items for tax and accounting purposes. These differences result in the recognition of deferred tax assets and liabilities, which are included within the consolidated balance sheet to the extent that we believe they are
recoverable.

In recognising deferred tax assets, the Group considers profit forecasts including the effect of exchange rate fluctuations on sales and
external market conditions. Where it is probable that a position may be successfully challenged by revenue authorities, a tax provision is created for the tax on the probable adjustment.

Managements judgement is required in determining the provision for income taxes, deferred tax assets and liabilities. Deferred tax assets have been recognised where management believes there are sufficient
taxable temporary differences or convincing other evidence that sufficient taxable profit will be available in future to realise deferred tax assets.

Although the deferred tax assets which have been recognised are considered realisable, actual amounts could be reduced if future taxable income is lower than expected. This can materially affect the Groups reported net income and
financial position.

Hedge Accounting for Financial Instruments

The financial instruments that are used in hedging transactions are assessed both at inception and quarterly thereafter to ensure they are effective in offsetting changes in either the fair value or cash flows of
the related underlying exposures. Hedge accounting is used for foreign currency risk exposures and for firm and forecast commitments to hedge foreign currency risk exposures. Managements judgement is required to determine whether a future
transaction is probable. External market data is applied in measuring the hedge effectiveness of financial instruments. Hedge ineffectiveness is recognised immediately in the income statement. Refer to note 33 for details of the hedging
relationships as well as the impact of the hedge on the pre-tax profit or loss for the period.

Litigation and claims

The Group may be subject to claims, legal actions and complaints, including patent infringements, arising in the normal course of business. The likelihood and ultimate
outcome of such occurrences is not presently determinable therefore the Group uses estimation and judgement on whether any of these claims or litigation should result in a contingent liability being recognised.

Issues can, and do, take many years to resolve. Significant items of litigation and claims on which the Group has exercised accounting judgement in respect of whether
or not to recognise a contingent liability are discussed in note 27. The inherent uncertainty regarding the outcome of these items means eventual resolution could differ from the accounting estimates and therefore impact the Groups results and
cash flows.

6. Segmental Reporting

CSR is a leading provider of multifunction connectivity, audio and location platforms.

Products and Services from
which Reportable Segments Derive their Revenues

Following an internal reorganisation in the first half of 2009, the reportable segments of CSR
changed from those shown in the 2008 Annual Report and accordingly, the prior period disclosures have been restated.

The Groups new reportable
segments under IFRS 8 Operating Segments are as follows:



|                                        |  |

|Audio and Consumer Business Unit (ACBU) |  | Headsets, PC and Consumer Applications                      
|Automotive and PND (APBU)               |  | Automotive and Personal Navigation Device (PND) applications

Segment Revenues and Results

The reportable segments previously disclosed were Cellular and Non-Cellular.

The handset and headset businesses were previously included within the Cellular segment prior to the internal reorganisation and have now been split between HBU and
ACBU. The Non-Cellular reportable segment has now been split between the ACBU and APBU reportable segments.

The following is an analysis of the
Groups revenue and results by reportable segment:

6. Segmental Reporting (continued)

Segment Revenues and Results (continued)



Investment income and finance costs are not allocated to reportable segments for the purposes of reporting to the Groups Chief Executive Officer.

A substantial proportion of R&D costs are allocated to the handset business unit. Other operating costs are allocated on activity. This method of cost
allocation is used to report costs to the Groups Chief Executive Officer for the purposes of resource allocation and assessment of segment performance.

The accounting policies for the reportable segments are the same as the Groups accounting policies.

Underlying operating profit
represents operating profit earned by each segment without allocation, in each period, of acquisition-related fees, share-based payment charges, integration and restructuring charges, charges related to the amortisation of acquired intangible
assets, the adjustment to goodwill in respect of deferred tax in 2007 and 2008, the asset impairment charges in 2008, and in 2007, the patent dispute settlement.

In
March 2007, the UK Government announced that they would introduce legislation that reduced the corporation tax rate to 28% from 1 April 2008. This legislation was fully enacted. The deferred tax assets and liabilities, previously stated at 30%
of the temporary differences were remeasured to 28% of those amounts. In addition, the blended current tax rate for the 53 weeks ended 2 January 2009 reduced to 28.5%.

Adjustments to tax charge in respect of prior periods is due to the tax effect of acquisition accounting adjustments in 2009, the revision of the estimated tax benefits of research and development claims in 2008
and 2009 and remeasuring foreign exchange impacts on the recognised tax provisions in 2008.

Non-deductible expenses include items not deductible for
tax purposes such as legal and professional fees, and in 2008 and 2007, the unwinding of the discount on the contingent consideration and also some share option expenses. In 2007, this also included additional provision related to uncertain tax
positions.

$1.6 million of current tax benefit has been recognised in equity for a prior year deduction agreed with the tax authorities for the share
option gains of a former employee. We are in continuing discussions regarding an additional amount related to share option gains which if agreed would give a further benefit of up to five times the amount already recognised.

the time of the acquisitions of Clarity Technologies in 2005 and CPS Limited and NordNav Technologies AB in 2007, the acquired entities included brought forward tax losses. SiRF Technology Holdings Inc also included brought forward tax losses on
acquisition in 2009.

These were recognised only to the extent that deferred tax liabilities related to temporary timing differences existed. During
2007 and 2008, a further deferred tax asset was recognised for some of these losses related to Clarity Technologies Inc, and NordNav Technologies AB, and, in accordance with IFRS 3 (as issued in 2004), an equivalent adjustment was made to goodwill.
This resulted in a charge of $978,000 in 2008 (2007: $279,000) that was included within administrative expenses. During 2009, CSR plc implemented IFRS 3 (revised), this has resulted in a prospective change in accounting, and current year and future
deferred tax adjustments will not impact goodwill.

The estimated contingent consideration related to the 2007 acquisition of NordNav Technologies AB,
in line with current forecasts of the amount due under the sale and purchase agreement (note 22).

Goodwill acquired in a business combination is
allocated, at acquisition, to the cash generating units that are expected to benefit from that business combination. The carrying amount of goodwill has been allocated as follows:

In 2006,
goodwill acquired in a business combination was allocated to the single cash-generating unit. As a result of an internal reorganisation at the end of 2006, goodwill was reallocated to the cash generating units expected to receive the benefit based
on the relative fair value of each cash generating unit. Following the acquisition of SiRF Technology Holdings Inc, there was a further internal reorganisation; existing goodwill was allocated to the appropriate new cash generating units which
integrated the previous cash generating units and new SiRF goodwill arising on that acquisition was allocated to the cash generating units expected to receive the future benefits of the acquisition such as the expected revenue synergies and cost
savings.

Goodwill of $139.6 million was recognised on the acquisition of SiRF during 2009. Of this, $84.1 million was allocated to the handset cash
generating unit, $12.8 million was allocated to the audio and consumer cash generating unit and $42.7 million was allocated to the automotive and PND cash generating unit, based on the expected future benefits for these cash generating units.

13. Goodwill (continued)



Also during the period, the estimated remaining consideration payable on the NordNav acquisition was adjusted from $17.5 million to $nil in line with current forecasts of the amount due under the
sale and purchase agreement, this adjustment decreased the goodwill allocated to the handset cash generating unit.

The Group tests goodwill annually
for impairment or more frequently if there are indications that goodwill might be impaired. Following the annual impairment test which takes place in the fourth quarter of each year, it was determined that no further impairment of goodwill is
required.

The recoverable amount of each cash-generating unit is determined from a value in use calculation. The key assumptions for the value in use
calculations are those regarding the discount rates, terminal growth rates, future growth in sales and expected changes to selling prices and direct costs during the period. These assumptions have been revised in the year in light of the continuing
difficult economic conditions, this has resulted in more conservative estimates about the future and specifically a reduction in the terminal growth rate used for the impairment calculation. Management estimates discount rates using pre-tax rates
that reflect current market assessments of the time value of money and the risks specific to CSR.

Changes in selling prices and direct costs are based
on historical information and expectations of future changes in the market.

The Group has conducted sensitivity analysis on a variety of scenarios on
the impairment test of each CGUs carrying value. The sensitivity analysis demonstrates that sufficient headroom exists to ensure the carrying value exceeds the recoverable amount for all reasonable scenarios likely to occur.

For all cash generating units the Group prepares cash flow forecasts derived from the most recent financial budget approved by management for the next year and
extrapolates cash flow forecasts for the following four years, based on long range plans. These long range plans are based on recent reports on the markets we operate in produced by independent analysts. Management uses this information to produce
realistic plans when combined with internal and customer specific information. The key factor in the cash flow forecasts is the ability to forecast revenue. A terminal value is included for the period beyond five years from the balance sheet date
based on the estimated cash flow in the fifth year and a terminal growth rate of 1.5% (2008: 2.5%). This terminal growth rate does not exceed the average long-term growth rate for the relevant markets.

The rate used to discount the forecast cash flows is 9% (2008: 9%; 2007: 9%).

The average
credit period taken on trade receivables is 40 days (2008: 58 days; 2007: 37 days). An allowance has been made for estimated irrecoverable amounts within trade receivables of $114,000 (2008: $3,000; 2007: $3,000). This allowance has been determined
by reference to past default experience. An allowance for credit notes and price adjustments has also been made within trade receivables of $557,000 (2008: $1,902,000; 2007: $150,000).

Before accepting any new customers, the Group uses a credit scoring system to assess the potential customers credit quality and define credit limits by customer. Credit limits and credit quality are regularly
reviewed.

It is the policy of the Group to only transact with creditworthy entities to mitigate the risk of default associated with trade receivables.
The Group provides for trade receivables based on amounts estimated as irrecoverable determined by reference to past default experience.

The directors
consider that the carrying amount of trade and other receivables approximates to their fair value.

Cash and Cash Equivalents

Bank balances and cash comprise cash held by the Group and short term bank deposits with an original maturity of three months or less. The carrying amount of these
assets approximates to their fair value.

Treasury Deposits and Investment

Treasury deposits and investments represent bank deposits and obligations of the United States treasury with an original maturity of over three months. Some of these amounts are held as FVTPL assets (see note 33).

Credit Risk

The Groups principal
financial assets are bank balances and cash, treasury deposits and trade and other receivables.

The credit risk on liquid funds and derivative
financial instruments is actively managed to limit the associated risk and counterparties are banks with high credit ratings assigned by international credit rating agencies.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS continued

17. Other Financial Assets (continued)

Credit Risk (continued)



Included in the Groups trade receivables balance are debtors with a carrying amount of $12,022,000 (2008: $7,590,000; 2007: $2,719,000) which are past due but
for which the Group has not provided, as there has been no significant change in the credit quality of the receivables and the amounts are still considered recoverable. $8.7 million of the past due but not provided trade receivables were received
within two weeks of the balance sheet date (2008: $6.0 million; 2007: $1.9 million).

Based on past experience, the Group believes that no impairment
allowance is necessary in respect of trade receivables not past due, other than for credit notes or price adjustments.

18.
Derivative Financial Instruments

Currency Derivatives

The Group utilises currency derivatives to hedge significant future transactions and cash flows. The instruments purchased are denominated in GBP.

At the balance sheet date, the total notional amount of outstanding forward foreign exchange contracts that the Group has committed is as below:

Certain deferred tax assets and liabilities have been offset where they relate to the same taxation authority and net settlement and offset is permitted. The following is the analysis of the deferred tax balances (after offset) for
financial reporting purposes:

|Deferred tax liabilities |  |               |  | (4,002         | ) |  | (8,208           | )
|Deferred tax assets      |  | 4,341          |  | 6,481          |   |  | 7,021            |

At the
balance sheet date, the Group has unused tax losses of $261,542,000 (2008: $126,588,000; 2007:$175,564,000) available for offset against future profits. A deferred tax asset has been recognised in respect of $39,334,000 (2008: $4,416,000; 2007:
$7,793,000) of such losses. No deferred tax asset has been recognised in respect of the remaining $222,208,000 (2008: $122,442,000; 2007: $167,771,000) due to the unpredictability of future profit streams within certain subsidiary entities. Included
in unrecognised tax losses are losses of $107,647,000 (2008: $34,381,000; 2007: $47,819,000) that will expire in 5-20 years. Other losses may be carried forward indefinitely.

At the balance sheet date, no deferred tax liability has been recognised on temporary differences of $3,239,000 ( 2008: $22,974,000, 2007: $14,754,000) relating to the unremitted earnings of overseas subsidiaries
as the Group is able to control the timing of the reversal of these temporary differences and it is probable that they will not reverse in the foreseeable future. The temporary differences at 1 January 2010 are significantly reduced from
the previous year as a result of a change to UK tax legislation which largely exempts from UK tax, overseas dividends received on or after 1 July 2009. The temporary differences at 1 January 2010 represent only the unremitted earnings of
those overseas subsidiaries where remittance to the UK of those earnings may still result in a tax liability, principally as a result of dividend withholding taxes levied by the overseas tax jurisdictions in which those subsidiaries operate.

As of 1 January 2010, the Group recognized deferred tax assets that exceed deferred tax liabilities by $4,341,000 in entities which have suffered
a loss in the current period. This is based on managements assessment that it is probable that the respective entities will have taxable profits against which the unused tax losses and deductible temporary differences can be utilized.

It is
the Groups policy to lease certain of its equipment under finance leases and purchase certain software licences under agreements containing deferred payment terms. The average lease term is 3.0 years. Interest rates are fixed at the contract
date; all of the agreements containing deferred payment terms are interest free. For the period ended 1 January 2010, the average effective borrowing rate was 0% (2008: 0.14%). All leases are on a fixed repayment basis and no arrangements have
been entered into for contingent rental payments.

Lease obligations with a present value of $326,000 (2008: $1,350,000; 2007: $1,045,000) are
denominated in Sterling. All other obligations are denominated in US dollars.

The Groups obligations under finance leases are secured by the
lessors right over the leased assets.

Trade creditors
and accruals principally comprise amounts outstanding for trade purchases and ongoing costs. The average credit period taken for trade purchases is 61 days (2008: 64 days; 2007: 54 days).

The directors consider that the carrying amount of trade and other payables approximates to their fair value.

For most suppliers, no interest is charged on trade payables. The Group has financial risk management policies in place to ensure that all payables are paid within
the credit time-frame.

consideration related to milestone payments for the acquisition of NordNav Technologies AB. The consideration will be settled in instalments if certain performance criteria are achieved before September 2010. In the previous reporting period, it was
believed these performance criteria would be met. As at 1 January 2010, management considers the payment of the consideration a remote possibility.

Onerous Lease
Provision

The Group has provided for the discounted anticipated costs of satisfying the terms of any onerous leases, less any anticipated income
from subletting the buildings. It is anticipated that the provision will be used over the remaining lease terms (6 years). The 2009 additional provision relates to onerous lease charges for buildings being vacated as part of the integration and
restructuring activities that took place after the acquisition of SiRF Technology Holdings, Inc. in June 2009.

Returns and Warranty Provision

The Group provides for the anticipated costs associated with contractual liabilities under standard warranty terms. It is anticipated that the provision
will be utilised within one year (see note 4).

Onerous Contract Provision

The Group has provided for the remaining costs due under a contract signed by SiRF Technology Inc in 2008. It was concluded prior to the completion of the acquisition that the intellectual property licensed under
the contract was not going to be utilised in any SiRF products. There are no benefits expected to be realised from this contract. The payments are expected to be made during 2010.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS continued

25. Reserves (continued)



The share premium account, capital redemption reserve and hedging reserve are not
distributable. The merger reserve arose on the combination of CSR plc and Cambridge Silicon Radio Limited and is not distributable.

The Employee
Benefit Trust Reserve represents the cost of shares in CSR plc purchased in the market and held by the CSR plc Employee Benefit Trust to satisfy options under the Groups share option schemes. Between 18 March 2008 and 25 March 2008,
the CSR Employee Benefit Trust (the Trust) purchased 3,222,813 ordinary shares at prices between £3.37 and £3.03. On 3 May 2007, the Trust purchased 334,890 ordinary shares at an average price of £7.41 pence per
share. Between 6 June 2007 and 7 June 2007, the Trust purchased 336,425 ordinary shares at an average price of £7.38 per share. Between 26 September 2007 and 28 September 2007, the Trust purchased 795,452 ordinary shares at an
average price of £6.24 per share.

The shares acquired by the Trust do not represent treasury shares for the purposes of the Companies Act
and therefore remain as issued share capital.

For accounting purposes, the treatment of the shares acquired by the Trust is different. In preparing the
consolidated Group accounts, the shares held by the Trust are treated as a deduction in shareholders equity.

26. Notes to the Cash Flow Statement (continued)



The acquisition of SiRF Technology Holdings Inc in the 52 weeks ended 1 January 2010
(see note 35) was a significant non cash transaction in the period as the consideration for the transaction was satisfied through the issuance of additional shares (see note 24).

Patent disputes

Broadcom Corp. v. SiRF Technology, Inc. and CSR plc, Case No. SACV08-546 (Central District of California, filed 14 May 2008)

On 14 May 2008, Broadcom Corporation (Broadcom) sued SiRF Technology, Inc. (SiRF) alleging infringement of four Broadcom patents. The
suit, captioned Broadcom Corporation v. SiRF Technology, Inc., Case No. SACV08-546, is pending in the Federal District Court for the Central District of California. SiRF responded to Broadcoms Complaint on 4 June 2008, denying
infringement and alleging counterclaims seeking, inter alia, judicial declarations that SiRF does not infringe the patents-in-suit and that the patents are invalid.

On 13 October 2009, Broadcom filed a First Amended Complaint (FAC) adding CSR plc (CSR) as a defendant and asserting additional claims for false advertising under the Lanham Act,
California Business and Professions Code section 17500, et. seq. (false advertising), and California Business and Professions Code section 17200, et seq. (unfair competition). Broadcom asserted each of its original and new claims against both SiRF
and CSR.

SiRF and CSR responded to Broadcoms FAC on 28 October 2009, denying infringement and alleging counterclaims seeking, inter alia,
declarations that SiRF and CSR do not infringe and that the patents are invalid. SiRF also asserted new counterclaims for (1) false advertising under the Lanham Act and California Business and Professions Code sections 17200, et seq. and 17500,
et seq., and for (2) frivolous litigation under section 17200.

The trial of this matter has been set for 16 November 2010. It is not possible
to predict the outcome of the litigation with any level of certainty. The Group intends to defend itself vigorously. No provision has been made in these financial statements because, it is not possible to make a reliable estimate of the outcome of
this litigation.

No provision was included as part of the acquisition accounting as it is not possible and was not possible at the time of the
acquisition to make a reliable estimate of the outcome of this litigation.

In the Matter of CERTAIN GPS DEVICES AND PRODUCTS CONTAINING SAME,
Investigation No. 337-TA-602 (initiated 7 May 2007)

On 7 May 2007, the International Trade Commission (ITC) initiated an
investigation of SiRF and other entities based on a complaint filed by Global Locate, Inc. (Global Locate). Global Locates complaint alleged a violation of the Tariff Act of 1930 (19 U.S.C. § 1337) based on SiRFs alleged
infringement of six patents. Broadcom later joined the action as a complainant, following its acquisition of Global Locate. On 8 August 2008, the administrative law judge (ALJ) issued an initial determination on Broadcom/Global
Locates claims, finding a violation of section 1337 with respect to the asserted patents. On 22 August 2008, the ALJ issued a recommended determination on remedy and bonding that, among other things, recommended an importation ban with
respect to certain of the allegedly infringing SiRF products.

On 15 January 2009, the ITC (1) issued a limited exclusion order prohibiting
the entry by SiRF and the other named respondents of unlicensed SiRF GPS chips, and products incorporating them, that had been found to infringe various claims of the asserted patents and (2) issued a cease-and-desist order against SiRF.
Finally, for any temporary importation of the relevant products during the Presidential review period for the ITCs decision, the ITC set the bond at 100% of the value of the imported products.

The ITCs decision became final on 16 March 2009, at the conclusion of the Presidential review period. On 1 May 2009, SiRF filed an appeal with the
United States Court of Appeals for the Federal Circuit asking that the Federal Circuit reverse the ITCs findings with respect to all six asserted patents. On 4 November 2009, the Federal Circuit heard oral argument of SiRFs appeal,
which remains pending. The Group continues to defend itself vigorously

No provision has been made in these financial statements because it is not
possible to make a reliable estimate of the outcome of these legal proceedings.

Securities Actions

a) U.S. District Court Cases

In February 2008, multiple
putative class action lawsuits were filed in the United States District Court for the Northern District of California against SiRF and certain of its officers and directors at that time. These complaints allege that SiRF, and certain of its

officers and directors, made misleading statements and/or omissions relating to its business and operating results in violation of the federal securities laws. These federal cases were
consolidated and on 8 January 2010, the court granted final approval of a negotiated settlement, which required SiRF to pay $2,900,000, inclusive of attorneys fees, all of which was covered by SiRFs insurance.

b) California State Court Cases

Two consolidated shareholder
derivative lawsuits were filed in February 2008 in the Superior Court of the State of California (Santa Clara County) against certain of SiRFs officers and directors at that time. These two lawsuits were consolidated with two shareholder
lawsuits filed in February 2009 relating to the SiRF-CSR Merger Agreement. On 22 May 2009, SiRF signed a Memorandum of Understanding pursuant to which it agreed to settle all of the aforementioned California state court litigation for $385,000.
The parties entered into a stipulation of settlement on 21 October 2009, and the settlement was preliminarily approved by the court on 23 December 2009. The court has scheduled a hearing on 16 April 2010 for consideration of final
approval of the settlement. SiRF continues to deny all allegations of liability, and denies that plaintiffs have suffered any damages. Any settlement would be entirely covered by SiRFs insurance.

Operating lease
payments represent rentals payable by the Group for certain of its office properties, office equipment and software licences. Leases are negotiated for an average term of 3.35 years and rentals are fixed for an average of 3.35 years.

29. Integration and restructuring

A
restructuring program was implemented at the end of Q2 2009, following the acquisition of SiRF Technology Holdings Inc. This led to almost 100 employees leaving the Group. The headcount reductions were implemented following careful consideration of
the long-term strategic objectives and shorter term targets for 2009 and 2010. This planning commenced prior to the acquisition date to ensure that once the Group was able to operate as a single business, the Group could integrate and restructure as
quickly as possible and ensure that the core projects of the enlarged Group were adequately resourced.

The main components of the $12.2 million charge
were onerous lease charges of $2.2 million, severance costs of $4.3 million, consultancy and legal costs of $4.5 million and $1.2 million of other integration related costs. Approximately 100 employees left the Group as part of the 2009 combined
integration and restructuring programme spread through [all] functions mostly in the UK and US.

At 1 January 2010, there were $0.6 million of
accruals in respect of remaining payments to be made to employees under the integration and restructuring programme; cash outflows relating to the onerous leases of buildings being vacated are expected to occur in the next year.

In 2008, CSR plc announced a restructuring programme in the fourth quarter with the aim of reducing ongoing operating expenses by around $20 million in 2009. This was
successfully completed and delivered the predicted savings. Approximately 100 employees left the Group as part of the 2008 restructuring programme spread through all functions mostly in the UK, US and Sweden. A one-time restructuring charge of $14.4
million was recorded in 2008 including $5.6 million of severance, $3.3 million of currency hedging charges (due to the reduction in Sterling requirements in 2009) and $3.9 million of onerous lease and building-related charges for buildings being
vacated as part of the restructuring. At 2 January 2009, there were no payments remaining to be made to employees under the restructuring programme; cash outflows relating to the onerous leases of buildings being vacated are expected to occur
in the next six years.

30. Impairment of
Assets

During 2008, a non-cash impairment charge of $52.9 million was recorded. This resulted from the decision to discontinue investment in
UbiNetics protocol software development programme following the recommendations of the Operational Assessment in April 2008.

During the
Assessment, the Group looked at its market in great detail and consulted widely to review the opportunities for winning in the global market for wireless solutions. The Group undertook in-depth discussions with customers on all continents, and asked
the leading customers where they anticipated the most growth. The Group also carried out an analysis of its own capabilities and identified strengths and weaknesses to determine our future strategy.

The impairment was charged to administrative expenses in the consolidated income statement.

31. Share-Based Payments

CSR plc has grants and awards in the following Share Schemes which
result in charges to the Income Statement:

Global Share Option Scheme

The Company has a share option scheme for all employees of the Group, under which share options were issued prior to flotation, at a price based on the most recent private funding round. All employees were granted
options on joining CSR. These options had a vesting period of five years, with 20% of options vesting one year after grant, then the remainder vesting in equal quarterly instalments over the remaining four years. Other options (in addition to those
related to employees joining) were also granted under this scheme. In all cases if the options remain unexercised after a period of ten years from the date of grant, the options lapse. Options are forfeited if the employee leaves the Group before
the options vest. No grants have been made under this scheme since flotation.

Company Share Option Plan (CSOP)

The Company introduced a new scheme at flotation called the CSR plc Share Option Plan. The following grants have been made under the scheme:

Flotation Grant

On the Companys flotation in February
2004, the Company issued share options to all employees, at a price based on the share price on the day of flotation. The vesting period was three years. If the options remain unexercised after a period of ten years from the date of grant, the
options lapse. Options are forfeited if the employee leaves the Group before the options vest.

Performance Grants

On the Companys flotation in February 2004, and in May 2005, May 2006, May 2007, June 2008 and certain other dates (relating to employees joining) the Company
issued share options at a price based on the average share price over the preceding three days. For options granted between 2004 and 2008, the vesting period of these grants is three years and vesting is dependent upon meeting certain EPS based
performance conditions. If the options remain unexercised after a period of ten years from the date of grant, the options lapse. Options are forfeited if the employee leaves the Group before the options vest.

With the decision to extend the grant of share awards with accompanying performance conditions to other employees, the Committee had decided that for grants in 2009,
the performance condition for vesting would be changed to Total Shareholder Return (TSR).

The vesting period of these share options remains three
years. The vesting of the options is also subject to the Group satisfying a performance condition based on the Total Shareholder Return of the Companys shares when compared to a group of companies selected at the time an award is first
granted. In order for the shares to vest, the Group must have met or exceeded certain TSR thresholds when compared with the TSR performance of the group of other companies.

Starter Grants

The Company grants options to new starters to assist in recruitment. Options are exercisable at
a price equal to the average share price on the three days preceding the grant date. The vesting period of the options is over a period of five years with 40% vesting after two years and 5% vesting each quarter thereafter. If the options remain
unexercised after a period of 10 years from the date of grant, the options lapse. Grants are forfeited if the employee leaves the Group before the options vest. The Company has also issued starter grants to senior employees that vest after three
years. No starter grants with these characteristics were issued in the current period.

31. Share-Based Payments (continued)



CSR Share Award Plan

In May 2005, following approval of shareholders at the 2005 Annual General Meeting, the Company introduced the CSR plc Share Award Plan, which allows for options to be
granted for exercise at a future date at a price equivalent to the nominal value of the Companys shares of £0.001. The following awards have been made:

Retention Awards

The Company issues certain employees with rights to purchase shares at nominal value
(£0.001) as a method of staff retention. The vesting period of these share awards is either two or three years. If the share awards remain unexercised after a period of ten years from the date of grant, the awards lapse. Awards are forfeited
if the employee leaves the Group before the options vest.

Performance Awards

The Company issues certain employees with rights to purchase shares at nominal value (£0.001) as a method of staff incentivisation. The vesting period of these share awards is three years. For grants between
2005 and 2008, the vesting of the awards is also subject to the Group satisfying two performance conditions. The first is the Total Shareholder Return of the Companys shares when compared to a group of companies selected at the time an award
is first granted. The second is improvement in the underlying financial performance of the Group. In order for the shares to vest, the Group must have met or exceeded certain TSR thresholds when compared with the TSR performance of the group of
other companies. In the event the Group satisfies any one of the TSR thresholds, the Remuneration Committee then considers the extent of any improvement in the underlying financial performance of the Group.

In 2009, the Company issued certain employees with rights to purchase shares at nominal value. The vesting period of these grants is three years and vesting is
dependent upon meeting certain EPS based performance conditions.

If the options remain unexercised after a period of ten years from the date of grant,
the options lapse. Options are forfeited if the employee leaves the Group before the options vest.

Starter Awards

The Company grants rights to new starters to purchase shares at nominal value (£0.001) to assist recruitment. The vesting period of these awards is two years. If
the share awards remain unexercised after a period of ten years from the date of grant, the awards lapse. Awards are forfeited if the employee leaves the Group before the options vest.

SAYE Schemes

The Company operates a SAYE scheme, whereby UK employees are allowed to subscribe to a monthly
savings amount for a period of three years; at the end of the three year period, the employee is allowed to either receive their saved amount plus interest or purchase shares in the Company at a price based on the average share price on the three
days prior to commencement of the SAYE scheme, discounted by 20%. This scheme is open to all employees subject to Inland Revenue approved limits on total investment, and invitations are issued at regular intervals. Employees have a period of six
months following the conclusion of the scheme to exercise their option to purchase shares.

Employee Stock Purchase Plan (ESPP)

The Company operates an ESPP scheme for its US employees whereby eligible employees are allowed to have salary withholdings of up to 15% of cash compensation to
purchase ordinary shares in the Company at a price equal to 85% of the lower of the fair market value of the shares on the first trading day of the offering period or the fair market value on the purchase date.

SiRF Technology Holdings Inc., plans

For purely historic
purposes of settling pre-acquisition obligations of option and award exercise, the Company has assumed all the obligations of the former SiRF Technology Holdings Inc. under pre-existing plans utilised by SiRF which comprise the 1995 Stock plan, the
2004 Stock Incentive Plan, the TrueSpan 2004 Stock Incentive Plan and the Centrality 1999 Stock Plan. The Company will not issue any options or awards under these plans going forward. All contractual terms of the assumed options remain the same,
except for the converted number of shares and exercise price which were based on an exchange ratio determined as part of the merger agreement.

31. Share-Based Payments (continued)

Company Share Option Plan (CSOP) (continued)



Expected volatility was determined by calculating the historical volatility of the Groups share price over a time period equivalent to the vesting period of the
options. The expected life used in the model has been adjusted based on managements best estimates, for the effects of non-transferability, exercise restrictions and behavioural considerations. The adjustments for the performance conditions
are reflected in the proportion of options anticipated to vest.

For options issued in 2009, the fair value was based upon Monte-Carlo simulation of the
performance of the 38 comparator companies included in the TSR conditions of the award. The Monte Carlo simulation incorporates a range of other assumptions based on the TSR comparator companies; those assumptions given above relate to the Group.

Expected volatility for each Company was determined by calculating the historical volatility of the individual Companys share price over the 3
years from the date of grant.

For pre-2009 awards,
the fair value was based upon Monte-Carlo simulation of the performance of the 38 comparator companies included in the TSR conditions of the award. Expected volatility for each Company was determined by calculating the historical volatility of the
individual Companys share price over the 3 years from the date of grant.

For awards issued in 2009, the fair value was based on the share price
on the date of grant as the performance conditions were market based.

ESPP scheme

The fair value of the ESPP awards was based upon the Monte Carlo simulation of the likely gain to be made by each employee over the course of the scheme.

Market
Risk

Market risk is the risk that changes in market prices, such as foreign currency exchange rates and interest rate risk will affect the
Groups income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimising the return on risk.

Market risk exposures are measured using sensitivity analysis.

Foreign Currency Risk Management

Substantially all of the Groups sales and costs of sales are denominated in US dollars, the
functional currency of all the entities within the Group. A substantial proportion of the Groups fixed costs are denominated in Sterling and the majority of the remainder is non-USD denominated. This exposure to different currencies may result
in gains or losses with respect to movements in foreign exchange rates and the impact of such fluctuations could be material. Accordingly, the Group enters into hedging transactions pursuant to which it purchases Sterling under forward purchase
contracts in order to cover the majority of its Sterling exposure.

The carrying amounts of the Groups Sterling denominated monetary assets and
liabilities at the reporting date are as follows:

|             |  |               |   |  |               |   |  |                 |   |  |               |  |               |  |

Foreign
Currency Sensitivity Analysis

A 10 percent strengthening of the US dollar against GBP sterling would have decreased equity and profit or increased
loss after tax by the amounts shown below as at the reporting date shown. In managements opinion, this is a reasonably possible change given current market conditions.

Foreign Currency Sensitivity Analysis (continued)



This analysis assumes that all other variables, in particular interest rates and other foreign currencies, remain constant. The analysis is performed on the same basis
for 2008 and 2007.



|               |  |        |   |  |                  |

|GBP              |  | (10,919 | ) |  | (1,052           | )

A 10
percent weakening of the US dollar against GBP sterling would have had the equal but opposite effect, on the basis that all the other variables remain constant.

The movement in loss for the period is mainly attributable to the Groups exposure to exchange movements in sterling denominated monetary assets and liabilities. The movement in equity is mainly as a result of the changes in fair value
of forward foreign exchange contracts.

Forward Foreign Exchange Contracts

The following table indicates the periods in which the cash flows associated with derivatives that are cash flow or fair value hedges are expected to occur:

The Directors
consider the periods in which the cash flows associated with the derivatives that are cash flow hedges are expected to occur approximate the periods when the cash flows associated with those cash flows are likely to impact profit or loss.

Interest Rate Risk Management

The Group has no
significant direct exposure to fluctuations in interest rates other than those on interest-bearing cash balances. The majority of cash balances are held at fixed rates of interest and the effective rate of interest on those cash balances in the
period was 0.54% (53 weeks ended 2 January 2009: 4.67%; 52 weeks ended 28 December 2007: 5.16%).

Credit risk

Credit Risk Management

Credit risk refers to the risk that a
counterparty will default on its contractual obligations resulting in financial loss to the Group. The Group has adopted a policy of only dealing with creditworthy counterparties and obtaining sufficient collateral where appropriate, as a means of
mitigating the risk of financial loss from defaults. The Group only transacts with entities that are rated the equivalent of investment grade and above for Treasury management purposes. This information is supplied by independent rating agencies
where available and if not available, the Group uses other publicly financial available information and its own trading records to rate its major customers. The Groups exposure and the credit ratings of its counterparties are continuously
monitored and credit exposure is controlled by counterparty limits.

The credit risk on liquid funds and derivative financial instruments is limited
because counterparties are banks with high credit ratings assigned by international credit rating agencies.

For cash and cash equivalents and treasury
deposits, the Company only transacts with entities that are equivalent to investment grade and above.

Disclosures related to the credit risk associated
with trade receivables are in note 17.

Liquidity risk

Liquidity Risk Management

The Group manages liquidity risk by maintaining adequate cash reserves and by continuously monitoring forecast
and actual cash flows and matching the maturity of financial assets and liabilities. The Group has no significant borrowings from third parties and therefore liquidity risk is not considered a significant risk at this time. The table below details
the Groups remaining contractual maturity for it non-derivative financial liabilities with agreed repayment periods. The tables have been prepared based on undiscounted cash flows of financial liabilities based on the earliest date on which
the Group can be required to pay.

Fair Value of Financial Instruments

The fair values of
financial assets and liabilities are determined as follows:

Trade receivables and trade and other payables: The carrying amount of these short-term
financial instruments approximates their fair value.

Derivatives: The fair value is estimated by discounting the difference between the contractual
forward price and the current forward price for the residual maturity of the contract using an appropriate discount rate.

The carrying amounts of
financial assets and liabilities in the financial statements approximates their fair values.

The following table provides an analysis of the financial
assets, specifically money market funds and marketable debt instruments that are measured on a recurring basis, subsequent to initial recognition at fair value, grouped into Levels 1 to 3 based on the degree to which the fair value is observable as
at 1 January 2010:

Level 1 fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or
liabilities;

Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the
asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

Level 3 fair value measurements are those derived
from valuation techniques that include significant inputs for the asset and liability that are not based on observable market data (unobservable inputs)

35. Acquisition of subsidiary (continued)

SiRF Technology Holdings, Inc. (under IFRS 3 (revised 2008)) (continued)



The goodwill arising on the acquisition of SiRF Technology Holdings Inc, is attributable to the anticipated profitability of the
Groups products in the GPS market and the anticipated future operating synergies from the combination. It is not anticipated that the goodwill will be tax deductible.

SiRF Technology Holdings Inc contributed $130.0 million to revenue and a profit of $21.4 million to loss before tax for the period between the date of acquisition and the balance sheet date.

If the acquisition of SiRF Technology Holdings Inc had been completed on the first day of the accounting period, Group revenues for the period would have been $683.9
million and Group loss would have been $14.1 million but this does not reflect any synergistic benefits of the acquisition.

A contingent liability has
not been recognised on acquisition for the litigation described in note 27 as the fair value of the liability cannot be reliably measured as it was not possible at the time of the acquisition and has not been possible since to make a reliable
estimate of the outcome of this litigation due to the inherent uncertainty of litigation and the early stage of proceedings.

Cambridge Positioning
Systems Limited (under IFRS 3 as issued in 2004)

On 12 January 2007, the Group acquired 100% of the issued share capital of Cambridge Positioning
Systems Limited for a consideration of $35.0 million.

The
goodwill of $63.7 million arising on the acquisition of NordNav Technologies AB is attributable to the anticipated profitability resulting from NordNav Technologies ABs software-based GPS solution. The value of the assembled workforce of
NordNav Technologies AB was not recognised as a separately identifiable intangible assets and its value was subsumed into goodwill.

NordNav
Technologies AB contributed $191,000 to revenues and reduced the Groups profit before tax by $2,330,000 between the date of acquisition and the balance sheet date.

If the acquisition of NordNav Technologies AB had been completed on the first day of the financial period, Group revenues for the period would have been $848,625,000 and Group profit attributable to equity holders
of the parent would have been $112,355,000.

36. Patent Dispute Settlement

During 2007, the Group reached an agreement with the Washington Research Foundation (WRF) to settle the patent infringement suit issued against 12 of the Groups
customers. The complaint referred to certain U.S. patents owned by the University of Washington claimed to be relevant to Bluetooth chips.

The Group
remained of the view that WRFs infringement suit was without merit. Notwithstanding this, the Group believed that an early resolution of the claim was both in the Group and the Groups customers best interests and accordingly a payment of
$15.0 million was made in April 2007.

equivalents

Bank balances and cash comprise cash held by the Company and short term bank deposits with an original maturity of three months or less.
The carrying amount of these assets approximates their fair value.

45. Contingent consideration (continued)



The contingent consideration relates to milestone payments for the acquisition of NordNav
Technologies AB. The consideration is due to be settled in instalments once certain performance criteria have been achieved. In 2009, it was determined that these performance criteria would not be met and the liability was derecognised.

NOTES TO THE COMPANY FINANCIAL STATEMENTS Continued

48. Financial instruments (continued)

Categories of financial instruments (continued)



At the
reporting date there are no loans and receivables designated at fair value through profit and loss. The carrying amount reflected above represents the Companys maximum exposure to credit risk for such loans and receivables.

Financial risk management objectives

The Group Treasury
function provides services to the Company, co-ordinates access to domestic and international financial markets and monitors and manages the financial risks relating to the operations of the Company.

The main risks the Company is exposed to are the currency risk component of market risk, credit risk, and liquidity risk.

Foreign currency risk management

The Company does not seek to
manage the currency risk component of market risk as these risks are managed on a Group level. The Company does not enter into any financial derivative contracts. The Company does not enter into, or trade financial instruments, including derivative
financial instruments, for speculative purposes.

Foreign currency sensitivity analysis

The sensitivity analysis below has been determined based on the exposure of the Company to foreign currency movements for its non-derivative financial instruments at
the balance sheet date.

If the US dollar had strengthened by 10 percent against GBP sterling, the Companys:



| | · |  | Loss for the 52 week period ended 1 January 2010 would have decreased by $946,000. Loss for the 53 week period ended 2 January 2009 would have
decreased by $1,017,000. In both periods, this is mainly attributable to the Companys exposure to foreign exchange movements on Sterling denominated monetary assets and liabilities;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · |  | there is no impact on other equity reserves (2008: $nil).
| | - |  | ---------------------------------------------------------

A 10 percent weakening of the US dollar against GBP sterling would have had the equal but opposite effect, on the basis that all the other variables remain constant.

In managements opinion, this is a reasonably possible change in currency rates given current market conditions. This analysis assumes all other variables, in
particular interest rates and other foreign currencies, remain constant. The analysis is performed on the same basis for 2008.

Interest rate risk
management

The company has no significant direct exposures to fluctuations in interest rates other than those on interest bearing cash balances. The
majority of cash balances are held at fixed rates of interest and the effective rate of interest on those balances in the period was 0.54% (2008: 4.67%).

Credit risk management

Credit risk refers to the risk that counterparties will default on their contractual obligations resulting in
financial loss to the Company. For cash and cash equivalents and treasury deposits, the Company only transacts with entities that are equivalent to investment grade and above and Group treasury policy dictates that less than 20% of the total balance
on cash and equivalents and treasury deposits will be placed on term deposit with counterparties who have a Moodys credit rating of less than Aa1. Other financial assets consist of amounts receivable from related parties. The Companys
exposure to significant concentration of credit risk on receivables from related parties is detailed in note 49.

Liquidity risk management

Ultimate responsibility for the liquidity risk management of the Company rests with the Board of Directors which manages the liquidity requirements
of the Company in terms of short, medium and long-term funding requirements. The Company manages liquidity risk via the Groups Treasury function using sources of financing from other Group entities and investing excess liquidity. The Company
manages excess reserves by continuously monitoring forecast and actual cash flows and matching maturity profiles of financial assets and liabilities.

DIRECTORS REPORTCORPORATE AND SHARE
INFORMATION

Directors report  Corporate and share information




History and Development CSR plc is
the holding company of an international group of companies the principal activities of which are the design and supply of integrated circuits or silicon chips for wireless connectivity. CSR is domiciled in England and Wales and its registered office
and principal place of business is at Churchill House, Cambridge Business Park, Cowley Road, Cambridge CB4 0WZ and its telephone number is +44 (0) 1223 692000. CSR was established in Cambridge in April 1999 by an engineering and marketing team that previously worked at Cambridge Consultants Limited, a technology and consulting firm based in Cambridge that transferred
certain assets, including the assignment and license on a non-exclusive royalty free basis of intellectual property rights, to CSR in exchange for ordinary shares. CSR plc (the holding company) was incorporated and registered in England and Wales on 26 March 2001 with the name Cambridge Silicon Radio Holdings Limited (registered number 04187346), as a private company
limited by shares under the U.K. Companies Acts. On 10 July 2001, CSR was re-registered as a public company limited by shares with the name Cambridge Silicon Radio Holdings PLC; on 25 October 2002, CSR was re-registered as a private company
limited by shares with the name Cambridge Silicon Radio Holdings Limited; and on 19 February 2004, it was re-registered as a public company limited by shares with the name CSR plc. CSR ordinary shares were admitted to the Official List of the U.K.
Listing Authority and to trading on the main market of the London Stock Exchange in March 2004 and CSR is a constituent of the FTSE 250 Index. Beginning in 2005, we have sought to broaden our technological base and product range through a series of acquisitions, as follows:  ·

In March 2005, we acquired Clarity Technologies, Inc. for $17.1 million, in cash.  ·

In August 2005, we acquired the software business of UbiNetics (VPT) Limited for $48 million in cash. In May 2008, as a result of an operational strategy
assessment we decided to cease our ongoing investment and write off the


investment we had made in the UbiNetics protocol software development program, which had been acquired with the software business of UbiNetics in August 2005.  ·

In January 2007, we acquired NordNav for an initial consideration of $40 million, in cash. In 2008, we paid a further consideration of $17.5 million in cash.
Through this acquisition, we acquired early-stage GPS technology and intellectual property to develop a software-based GPS solution.  ·

In January 2007, we also acquired CPS for $35 million in cash. Through this acquisition, we acquired specialized location system technology to address solutions
when GPS signals may be unavailable (e.g., indoors).  ·

In June 2009, we acquired the GPS-based business of SiRF, for a consideration satisfied by the issue of shares in CSR plc to holders of SiRF Common Stock as at
26 June 2009 at a ratio of 0.741 of a CSR ordinary share for each SiRF share, which at 26 June 2009, valued SiRF at $281.5 million. Through the transaction, we acquired a leader in semiconductor-based GPS location platforms with strong
hardware, software and system capabilities, as a further step towards building on our leading position in the Connectivity Centre. Sales and Marketing CSRs sales and marketing function is centered in Cambridge with sales liaison offices in Dallas and
Detroit, United States; Taipei, Taiwan; Seoul and Gumi, South Korea; Tokyo, Japan; and Shanghai and Shenzhen, China. CSR markets to OEMs and ODMs,
principally through its direct sales force and, in North America, through sales representatives. CSR also markets its products through a global network of distributors. CSRs marketing efforts are supported by a team of applications engineers who provide technical support and assistance to existing and potential customers in

designing, testing and qualifying systems that incorporate its products. This support is generally provided without charge to customers who have the potential to purchase large volumes of
products. An important part of CSRs marketing effort involves providing technical support to product developers to encourage them to design
products using CSRs chips. For this purpose, CSR provides a range of development kits and tools. For a discussion of CSRs revenue by product segment, see Business and Financial Review  Financial Performance  Segment
Analysis of this annual report. For a discussion of CSRs revenues by geographic area, see Business and Financial Review  Financial Performance  Geographical Analysis of this annual report. Manufacturing and Assembly CSR is a
fabless semiconductor company. Because CSR uses independent fabrication facilities to manufacture its products, we subcontract wafer fabrication and assembly to Taiwan Semiconductor Manufacturing Company, (or TSMC), in Taiwan, IBM in the
United States, Samsung in South Korea and STMicroelectronics in Italy and France. We also subcontract assembly, testing and shipping to Advanced Semiconductor Engineering, (or ASE), in Taiwan, STATS ChipPAC Limited, (STATS) in Korea and Malaysia,
Amkor Technology Inc in Taiwan and China, Siliconware Precision Industries Limited in Taiwan, Samsung in South Korea, ST Microelectronics in Italy and France, Signetics Corp in Korea and King Yuan Electronics Co., Ltd (KYEC) in Taiwan. We also rely
on Global Uni Chip, a design foundary, to provide turnkey solutions for our system on chip, or SoC products. We do not have any long-term contracts with any of these third parties, and thus have no assurance as to their long-term availability or
cost. Prior to the acquisition of SiRF, all wafer fabrication, test, assembly and packaging was subcontracted to TSMC and ASE. As part of the
integration of SiRF following the acquisition in June 2009, we added additional partners to our supply chain who had previously supported SiRF in order to enable the enlarged portfolio of products to be supplied to our customers. Through all these
subcontractors we work to ensure that the Group is able to maintain sufficient capacity to support the demand for our integrated circuits, which can be affected in the event of a loss of


capacity at a supplier due to events affecting their business, or increased demand from our competitors which may mean we are unable to secure the volumes of products we require to meet customer
demand. Raw Materials CSR
sources the manufacture of its silicon wafers, and sources the testing of wafers and packaging of its integrated circuits from various subcontractors named above, who have facilities spread across multiple locations, primarily in the Asia Pacific
region. CSR also purchases flash memory from a sole supplier, SST, and certain other passive components from other suppliers. These passive components are standard components capable of being obtained through alternative sources, subject to the
conduct of a product qualification process prior to adoption into manufacturing. Seasonality CSR has historically experienced increased net revenue in its second and third quarters primarily due to seasonal demand related to the holiday season and end of
calendar year spending patterns in corporate budgets. Due to continued economic uncertainty and other factors, past historical patterns should not be considered a reliable indicator of CSRs future net revenue or financial performance and
historical seasonal patterns may not recur. Governmental Regulation CSR is not aware of any governmental regulations that would have a material effect on its business. Intellectual Property Our success and ability to compete depends to a significant degree upon
the protection of our proprietary technology. As of 1 January 2010, we had 582 patents granted worldwide. Of this total, CSR has 250 patents granted in the United States and 332 patents granted in other territories, with expiration dates ranging
from 2010 to 2029, along with 284 pending patent applications in the United States and 485 pending patent applications in other territories. We intend to continue to assess appropriate occasions for seeking patent protection for those aspects of our
technology that we believe provides significant competitive advantage. Although we file patents to protect our inventions, our revenue is not

dependent on any particular patent. We do not believe that the expiration or loss of a particular patent would materially harm our business. CSRs Bluetooth products use the Bluetooth trademark, which is owned by the Bluetooth SIG, or special interest group, a trade association of which CSR is a
member. Any company incorporating Bluetooth wireless technology into products or services, or re-branding a product with Bluetooth technology, must become a member of the Bluetooth SIG. The Bluetooth trademark is licensed on a worldwide,
royalty-free, non-exclusive, non-transferable, personal basis for use by companies that are incorporating qualified Bluetooth wireless technology into their products. CSR is a member of the Bluetooth SIG and licensee of the Bluetooth trademark.

1.59 Major Shareholders Information regarding our major shareholders is disclosed on page 90. None of the holders of CSR ordinary
shares has voting rights that differ from those of other shareholders. As of 1 March 2010, there were 98 shareholders with a US address on the register of shareholders, representing approximately 0.64% of CSRs outstanding share capital.
Because many of our ordinary shares are held by brokers and nominees, the number of record shareholders in the US may not be representative of the number of US beneficial shareholders of our ordinary shares. CSR is not directly or indirectly owned
or controlled by any government, person or other legal entity. There are no arrangements known to CSR that could result in a change of control of CSR.

At the AGM scheduled to be held on 19 May 2010, the Company proposes to amend the Articles of Association to reflect the full implementation of the
Companies Act 2006 on 1 October 2009. Objects and purposes CSR plc was incorporated and registered in England and Wales on 26 March, 2001 with the name Cambridge Silicon Radio Holdings Limited, as a private company limited by shares under the UK Companies Acts. On
10 July, 2001, CSR was re-registered as a public company limited by shares with the name Cambridge Silicon Radio Holdings PLC; on 25 October, 2002, CSR was re-registered as a private company limited by shares with the name Cambridge
Silicon Radio Holdings Limited; and on 19 February, 2004, it was re-registered as a public company limited by shares with the name CSR plc (registered number 04187346). The Memorandum of Association of CSR provides that the Companys objects are to carry on the business of a holding company, the development and design of electronic hardware and computer software and other
objects more particularly set out in Clause 4 of the Memorandum of Association. Since 1 October 2009, the Companies Act 2006 treats certain clauses of the Memorandum of Association, including Clause 4, as part of the Companys Articles of
Association. However, the Companies Act 2006 abolishes the need for companies to have an objects clause and for this reason, the Company is proposing to remove its objects clause at the 2010 AGM. Directors The business of the Company is conducted under the
supervision of the Board. Conflicts of interest The UK
Companies Act requires a director of a company who is in any way interested, directly or indirectly, in a contract or proposed contract with the company to declare the nature and extent of his interest to the other directors of the company. The UK
Companies Act also requires that a director must avoid a situation where a director has, or could have, a direct or indirect interest that conflicts, or possibly may conflict, with the companys interests. It allows directors of public
companies to authorize such conflicts where appropriate, if a companys articles of association so permit. CSRs Articles of Association


provide that the Board may in specified circumstances authorize any matter that would otherwise involve a director breaching his duty under the UK Companies Acts to avoid a conflict of interest.
They also provide that, subject to authorization of such conflict, a director may retain any benefit derived by reason of that interest. Director
compensation The Board sets the Companys remuneration policy. The Remuneration Committee determines on behalf of the Board, specific remuneration
packages for each of the executive directors and for the Chairman. Only non-executive directors serve on the Remuneration Committee and the members of the Remuneration Committee are independent of executive management. The Remuneration Committee
monitors and provides guidance on the level and structure of remuneration for senior management who report to the Chief Executive Officer. The Board itself determines the remuneration of the non-executive directors. No director may participate in
discussions relating to his or her own terms and conditions of service or remuneration. Borrowing powers The Board may exercise the Companys borrowing powers. Save with the previous sanction of an ordinary resolution, such borrowing powers are restricted where the
principal amount outstanding of all borrowings is equal to the greater of £300,000,000 and three times the Companys adjusted capital and reserves. Retirement At every annual general meeting, any director who (a) has been appointed by the Board since the last annual general meeting, or
(b) held office at the time of the two preceding annual general meetings and did not retire at either of them, or (c) has held office with the Company, other than employment or executive office, for a continuous period of nine years or
more at the date of the meeting, shall retire from office and may offer himself for re-appointment by the members. Director qualifying shares Directors of the Company are not required by the Memorandum or the Articles of Association to hold any shares in the Company.

Rights and restrictions attaching to the shares Dividend rights The shareholders may by ordinary resolution from time to time declare dividends not exceeding the amount recommended by the
Board. The Board may pay interim dividends, and also any fixed rate dividend, whenever the financial position of CSR, in the opinion of the Board, justifies its payment. If the Board acts in good faith, it is not liable to holders of shares with
preferred or similar rights for losses arising from the payment of interim or fixed dividends on other shares. The Board may withhold payment of all or
any part of any dividends or other moneys payable in respect of CSRs shares from a person with a 0.25% interest if such a person has been served with a restriction notice after failure to provide CSR with information concerning interests in
those shares required to be provided under the UK Companies Act. The Board may, if authorized by an ordinary resolution, offer shareholders (excluding
any member holding shares as treasury shares) in respect of any dividend the right to elect to receive shares by way of scrip dividend instead of cash. Any dividend unclaimed after a period of 12 years from the date when it was declared or became due for payment must be forfeited and revert to CSR. CSR may stop sending checks, warrants or similar financial instruments in payment of
dividends by post in respect of any shares or may cease to employ any other means of payment, including payment by means of a relevant system, for dividends if either (i) at least two consecutive payments have remained uncashed or are returned
undelivered or that means of payment has failed or (ii) one payment remains uncashed or is returned undelivered or that means of payment has failed and reasonable inquiries have failed to establish any new postal address or account of the
holder. In addition, CSR must resume sending dividend checks, warrants or similar financial instruments or employing that means of payment if the holder requests such resumption in writing. Voting rights Under English law, a shareholder who is present in
person and entitled to vote at a shareholders meeting is entitled to one vote on a show of hands regardless of the number of shares he or she holds. Every proxy present who has been duly appointed by a


shareholder entitled to vote on the resolution has one vote on a show of hands, unless the proxy is appointed by more than one shareholder in which case the proxy has one vote for and one vote
against if the proxy has been instructed by one or more shareholders to vote for the resolution and by one or more shareholders to vote against the resolution. The Articles of Association provide that resolutions put to a vote at a shareholders meeting will be decided on a show of hands, unless a poll is demanded by: (a) the chairman of the meeting; (b) not less than five members
present in person or by proxy and entitled to vote; (c) a member or members present in person or by proxy and representing not less than one-tenth of the total voting rights of all the members having the right to vote at the meeting; or
(d) a member or members present in person or by proxy and holding shares in CSR conferring a right to vote at the meeting being shares on which an aggregate sum has been paid up equal to not less than one-tenth of the total sum paid up on all
the shares conferring that right. A demand for a poll may be withdrawn with the consent of the chairman of the meeting at any time before the close of
the meeting or the taking of the poll, whichever is the earlier. A demand so withdrawn shall not invalidate the result of a show of hands declared before the demand was made. Under English law, any shareholder entitled to attend and vote at a meeting is entitled to appoint a proxy to exercise all or any of his rights to attend, speak and vote at a meeting of the company. Generally under English law, two shareholders present in person or by proxy constitute a quorum for the purpose of a general meeting, unless the companys
articles of association specify otherwise. The Articles of Association specify that two members present in person or by proxy and entitled to vote constitute a quorum for all purposes. At each annual general meeting of shareholders, directors are elected to fill the vacancies resulting from the retirement of directors described above under Directors  Retirement. Accordingly, not
all directors stand for election each year. The Memorandum and Articles of Association do not provide for or permit cumulative voting.

Under the Articles of Association, no member is entitled to vote at any general meeting or class meeting in respect
to any share held by him if any call or other sum then payable by him in respect of that share remains unpaid or if a member has been served with a restriction notice after failure to provide CSR with information concerning interests in those shares
required to be provided under the UK Companies Act. Rights to share in profits Other than the provisions outlined above in relation to dividends that have been declared and the provisions below in relation to rights on a liquidation of CSR, shareholders have no rights to share in the profits
of CSR. Pre-emptive rights Subject to the UK Companies
Act, any equity securities issued by CSR for cash must first be offered to CSR shareholders in proportion to their existing holdings of CSR ordinary shares. The UK Companies Act and the listing rules made by the UK Listing Authority, or the listing rules, allow for the disapplication of pre-emption rights, which may be waived by a special resolution of CSR shareholders, either generally or
specifically, for a maximum period not exceeding five years. Liquidation rights The rights of shareholders to share in any surplus in the event of liquidation are not expressly dealt with in the Memorandum and Articles of Association. Under English law, if CSR is wound up (whether the
liquidation is voluntary, under supervision of the Court or by the Court), the liquidator is under a duty to collect in and realize the assets of CSR and to distribute them to CSRs creditors and, if there is a surplus, to CSR shareholders
according to their entitlements. This applies whether the assets consist of property of one kind or of different kinds. Redemption provisions Subject to the provisions of the UK Companies Act and the listing rules, CSR may purchase or contract to purchase any of its ordinary shares on or
off-market. CSR may only purchase its ordinary shares out of distributable reserves or the proceeds of a new issue of shares made for the purpose of funding the repurchase.


Sinking fund provisions CSR shares are not subject to any sinking fund provision under its Memorandum or Articles of Association or under English law. Capital calls Shareholders have no liability for capital calls by the Company except with respect to the unpaid amount, if any, respecting their shares consisting of
the nominal value of the shares and any premium which may be payable on those shares. The directors can call on shareholders to pay such amounts that have not yet been paid to the Company for their shares. Provisions applicable only to significant shareholders There are no
provisions in the Memorandum or Articles of Association discriminating against a shareholder as a result of his or her ownership of a substantial number of shares. Variation of rights The Articles of Association provide that the rights attached to any class of shares may be
varied with the written consent of the holders of not less than three-fourths in nominal value of the issued shares of that class (calculated excluding any shares held as treasury shares), or with the sanction of a special resolution passed at a
separate general meeting of the holders of those shares. At every such separate general meeting (except an adjourned meeting) the quorum must be two persons holding or representing by proxy not less than one-third in nominal value of the issued
shares of the class (calculated excluding any shares held as treasury shares). The rights conferred upon the holders of any shares are not, unless
otherwise expressly provided in the rights attaching to those shares, deemed to be varied by the creation or issue of further shares ranking equally with them. General meetings The Articles of Association rely on the UK Companies Act provisions dealing with the calling of general meetings. An
annual general meeting of shareholders must be held once in every year within a period of six months beginning with the day following CSRs accounting reference date (which is December 31). CSRs Board may convene a general meeting of
shareholders whenever they think fit or where they are requisitioned to do so by CSR shareholders in accordance with the UK Companies Act.

General meetings may be held at such time and place as may be determined by CSRs Board. An annual general meeting must be convened on at least 21
days written notice to shareholders entitled to receive notices. General meetings must be convened on at least 21 days written notice unless the requisite majority of shareholders has agreed to short notice. Two shareholders must be
present in person or by proxy and entitled to vote to constitute a quorum for all purposes at general meetings of CSR. Limitation on voting rights Persons who are neither residents in the UK nor UK nationals may freely hold, vote and transfer shares in the same manner as UK residents or
nationals. Any member whose registered address is not within the UK can give the Company a postal address within the UK at which notices may be served on him. Otherwise, a member whose registered address is not within the UK is not entitled to
receive any notice from the Company. Change of control The Company can issue additional shares with any rights or restrictions attached to them as long as not restricted by any rights attached to existing shares. These rights or restrictions can be decided by the directors so long as there is
no conflict with any resolution passed by the shareholders. The ability of the directors to issue shares with rights or restrictions that are different than those attached to the currently outstanding ordinary shares could have the effect of
delaying, deferring or preventing change of control of the Company. In addition, as discussed above under Directors  Retirement,
directors stand for re-election at an annual general meeting only if they are required by the terms of the Articles of Association to have retired from office in connection with such annual general meeting. As a result, not every director stands for
re-election at each annual general meeting. Because this would prevent shareholders from replacing the entire board at a single meeting, this provision could also have the effect of delaying, deferring or preventing a change in control of the
Company. Disclosure of interests in shares The
UK Financial Services Authority and Disclosure and Transparency Rules impose an obligation upon a person who acquires or ceases to have notifiable


interest in the relevant share capital of a public company to notify the company of that fact within two days (excluding weekends and bank holidays) of his or her knowing of its occurrence. The
disclosure threshold is 3%. In addition, the UK Companies Act provides that a public company may, by notice in writing, require a person whom the
company knows or reasonably believes to be or to have been within the three preceding years, interested in the companys issued voting share capital to (1) confirm whether this is or is not the case, and (2) if this is the case, to
give further information that the company requires relating to his interest or any other interest in the companys shares of which he is aware. The Articles of Association provide that if the holder of any shares or a person who appears to be interested in those shares, fails to comply within the relevant period with any statutory notice in respect of those shares, or makes a
statement in response to the notice which is false or inadequate in a material particular, CSR may restrict the rights relating to the identified shares, following a restriction notice. The restriction notice will state that the identified shares no
longer give the shareholder any right to attend or vote either personally or by proxy at a shareholders meeting or to exercise any right in relation to the shareholders meetings. Where the identified shares make up 0.25% or more (in
amount or in number) of the existing shares of a class at the date of delivery of the restriction notice, the restriction notice can also contain the following further restrictions: (i) the Board can withhold any dividend or part of a dividend
or other money otherwise payable in respect of the identified shares without any right to he holder to receive any shares in lieu of dividend; and (ii) the Board can refuse to register a transfer of any of the identified shares which are
certificated shares unless the Board is satisfied that they have been sold outright to an independent third party. Once a restriction notice has been given, the Board is free to cancel it or exclude any shares from it at any time they think fit. In
addition, it must cancel the restriction notice within seven days of being satisfied that all information requested in the statutory notice has been given. Also, where any of the identified shares are sold and the Directors are satisfied that they
were sold outright to an independent third party, they must cancel the restriction notice within seven days of receipt of the notification of the sale. The Articles of

Association do not restrict in any way the provision of the legislation which apply to failures to comply with notices under the legislation. The UK City Code on Takeovers and Mergers imposes rigorous disclosure requirements affecting parties to a proposed takeover, their associates and persons
acting in concert in relation to the shares of a company. These requirements also extend to dealings by persons who directly or indirectly own or control (either before or as a result of the dealing) 1% or more of the equity shares in an
offeror or offeree company or of any other class of shares relevant to the offer in question. Rule 13d-1 of the U.S. Securities Exchange Act of 1934
requires that a person or group acquiring beneficial ownership of more than 5% of equity securities registered under that Act discloses such information to the SEC within 10 days after the acquisition. CSR is required by the listing rules of the UK Listing Authority to disclose in its annual report the identity and share interests of its directors and any persons
connected with them, as defined in the UK Companies Act, and of any person with an interest of 3% or more of its CSR ordinary shares. Persons
discharging managerial responsibilities (primarily directors and some senior executives), and their connected persons, must notify a public company such as CSR in writing of the occurrence of all transactions conducted on their own account in the
shares of the company, or derivatives or any other financial instruments relating to those shares within four business days of the day on which the transaction occurred. The notification must contain specified information, including the name of the
person involved, the type of transaction, the date on which it occurred, and the price and volume of the transaction. The public company must notify a regulatory news service (which will make the information public) of any information notified to it
in accordance with these provisions. The notification to a regulatory news service must be made as soon as possible, and in any event by no later than the end of the business day following the receipt of the information by the company.


Differences from law in host country With respect to the items described above, applicable UK law is not significantly different from applicable U.S. law. Changes in share capital CSR may by ordinary resolution increase, consolidate, or consolidate and then subdivide its shares or any of
them. Subject to the Companies Act, CSR, by resolution, may determine that, as between shares resulting from a subdivision, any of them may have a preference or advantage, or may be subject to restrictions as compared with the others. CSR may, by
special resolution, reduce its share capital, share premium account, capital redemption reserve or any other undistributable reserve. Material contracts Excluding contracts entered into in the ordinary course of business, no contracts have been entered into in
the two years preceding the date of this document by CSR or any other member of the Group that are considered material to its results or operations, other than the merger agreement with SiRF. On 9 February 2009, CSR entered into an agreement
and plan of merger with SiRF Technology Holdings, Inc., pursuant to which a subsidiary of CSR was merged with and into SiRF, with SiRF as the surviving corporation. Under the merger agreement, CSR issued ordinary shares to SiRF shareholders with a
total value of $281.5 million as of the date the acquisition was completed on 26 June 2009. This transaction is discussed further in the section entitled Business and Financial Review on page 10. Exchange Controls There are currently no
foreign exchange control restrictions on CSRs ability to pay dividends on its ordinary shares or on the conduct of its operations imposed by English law. There are currently no limitations on the right of non-residents or foreign owners to
hold or vote CSR ordinary shares imposed by English law or CSRs articles of association. Taxation (US Holders) US federal income tax matters The following general
discussion describes the material US federal income tax consequences of the

ownership of ordinary shares that are generally applicable to US holders (as defined below). However, this discussion does not address all aspects of taxation that may be relevant to particular
US holders in light of their personal investment or tax circumstances or to persons that are subject to special tax rules. In addition, this discussion does not address the tax treatment of special classes of US holders, such as banks, insurance
companies, tax-exempt entities, financial institutions, broker-dealers, persons holding ordinary shares as part of a hedging or conversion transaction or as part of a straddle, US expatriates, persons subject to the alternative minimum
tax, and non-US holders. This discussion may not be applicable to holders who acquired ordinary shares pursuant to the exercise of options or warrants or otherwise as compensation. Furthermore, this discussion of US federal income tax matters does
not give a detailed discussion of any state or local tax considerations or tax considerations with respect to any non-US jurisdiction. We urge you to consult your own tax advisor as to the specific tax consequences of the ownership of ordinary
shares, including the applicable US federal, state, local and foreign tax consequences to you of the ownership of ordinary shares. As used in this
discussion of US federal income tax consequences, a US holder means a holder of ordinary shares who or that holds such stock as a capital asset within the meaning of the Internal Revenue Code of 1986, as amended, or the Internal Revenue
Code, and is for US federal income tax purposes (i) a citizen or resident of the United States, (ii) a corporation or other entity taxable as a corporation organized under the laws of the United States, any State thereof or the District of Columbia,
(iii) a trust if a court within the United States is able to exercise primary jurisdiction over its administration and one or more US persons have authority to control all substantial decisions of the trust, or (iv) any person that is subject to US
federal income tax on its worldwide income. As used herein, a non-US holder refers to any holder of ordinary shares (other than a partnership) who is not a US holder. This discussion is based on the Internal Revenue Code, applicable Department of Treasury regulations, judicial authority, and administrative rulings and practice, all
as of the date of this annual report. This discussion is not binding on the US Internal Revenue


Service, or the IRS, or the courts. Future legislative, judicial, or administrative changes or interpretations, which may or may not be retroactive, may adversely affect the accuracy of this
discussion. Passive Foreign Investment Company Rules Special US federal income tax rules apply to US holders owning stock of a passive foreign investment company, or PFIC. A foreign corporation generally will be considered a PFIC for any taxable year in which (i) 75% or more of its gross
income is passive income, or (ii) 50% or more of the average value of its assets are considered passive assets (generally, assets that generate passive income). Based upon an analysis of CSRs holdings during the taxable year ended
January 1, 2010 of cash and liquid assets such as bank deposits and marketable securities (all of which are passive assets for these purposes) and CSRs share price for such period (which affects the valuation of certain assets,
including goodwill), CSR believes that it did not qualify as a PFIC for its taxable year ended January 1, 2010. Moreover, based on current projections of CSRs passive assets and expected share price, CSR believes that it will not qualify as a
PFIC for its taxable year ending December 31, 2010. However, the determination of whether a company is a PFIC is highly factual, and will depend, among other things, upon CSRs actual holdings of passive assets and share price during such
period. Given CSRs significant holdings of passive assets such as cash and marketable securities, if CSRs share price were to decline for an extended time to levels comparable to its low point during January 2009, it is possible that CSR
would be treated as a PFIC in a future taxable year. CSR will continue to monitor whether it qualifies as a PFIC, and will notify US holders of ordinary shares if it determines that it is a PFIC for a given taxable year. If CSR were classified as a PFIC for any taxable year during which US holders hold ordinary shares, US holders would be subject to special, adverse rules unless, as
described below, they make either a QEF election or a mark-to-market election with respect to their ordinary shares. Absent such elections, US holders gain from the sale or other disposition of ordinary shares and
excess distributions received from CSR would be ordinary income. Such income would be taxed as if the gain or excess distribution had been realized ratably over the US holders holding period and would be increased by an interest
charge

with respect to underpayments of tax as if the ratable portion of the gain or excess distribution with respect to a given prior taxable year had been subject to tax in such year. An excess
distribution generally would be any distribution to a US holder with respect to ordinary shares during a single taxable year that is greater than 125% of the average annual distributions received by such US holder with respect to ordinary shares
during the three preceding taxable years or, if shorter, during his or her holding period with respect to the ordinary shares. For these purposes, gifts, exchanges pursuant to corporate reorganizations, and pledges of ordinary shares for use as a
security for a loan may be treated as taxable dispositions. US holders who make neither a mark-to-market election nor a QEF election will be required
to file an IRS Form 8621 if they own ordinary shares in any year in which CSR is a PFIC and they receive a distribution from CSR or dispose of their CSR shares (and will also be required to file this form to make certain elections with respect to
their CSR shares). Mark-to-Market Election If ordinary
shares are considered to be traded on a qualified exchange or other market, US holders would not be subject to the foregoing PFIC taxation rules if they make a mark-to-market election with respect to their ordinary shares.
Although the determination of whether shares are traded on a qualified exchange or other market is factual and there is no specific authority that designates certain non-US exchanges as qualified exchanges, CSR expects that
US holders of ordinary shares will be able to make this election because CSRs shares are currently traded on the LSE. However, no assurance can be provided in this regard. After making such an election, US holders generally would include as
ordinary income in each year during which the election is in effect and during which CSR is a PFIC the excess, if any, of the fair market value of ordinary shares at the end of the taxable year over their adjusted basis in such ordinary shares. US
holders also would be allowed to take an ordinary loss in respect of the excess, if any, of their adjusted basis in ordinary shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income that
was previously included as a result of the mark-to-market election). US holders tax basis in ordinary shares would be adjusted to reflect any income or loss amounts resulting from a mark-to-market election. If


made, a mark-to-market election would be effective for the taxable year for which the election was made and for all subsequent taxable years in which CSR is a PFIC unless the ordinary shares were
not considered to be traded on a qualified exchange or other market or the IRS consented to the revocation of the election. For any year for which CSR is not a PFIC, the mark-to-market election is inoperative. US holders make the
mark-to-market election on IRS Form 8621, which must be filed along with their tax return for the taxable year for which the election is to take effect on or before the due date for such return (including extensions). US holders who decide to make
the mark-to-market election are advised to make the election for the first taxable year for which CSR is a PFIC. US holders must report income and loss with respect to the election for each year for which CSR is a PFIC on IRS Form 8621. QEF Election The PFIC taxation rules outlined above also would not
apply to US holders that elect to treat CSR as a qualified electing fund or QEF. US holders that are eligible for and timely make a QEF election, would include in income each year for which CSR is a PFIC (and would be subject
to current US federal income tax on) their pro rata share of CSRs ordinary earnings, as ordinary income, and net capital gains, as long-term capital gain, for the taxable year that ends with or within their taxable year, regardless of whether
such amounts are actually distributed. Any such ordinary income would not be eligible for the favorable rates applicable to qualified dividend income. Corporate US holders would not be eligible for a dividends received deduction in respect of such
income or gain. US holders adjusted tax basis in ordinary shares would be increased to reflect taxed but undistributed earnings and profits. Distributions of earnings and profits that had been previously taxed would result in a corresponding
reduction in US holders adjusted tax basis in ordinary shares and would not be taxed again. US holders would not, however, be entitled to a deduction for their pro rata share of any losses that CSR incurred with respect to any year. US holders may only make a QEF election if CSR provides them with the information needed to determine CSRs ordinary earnings and net capital
gains. If it is a PFIC, CSR will provide US holders with the information that is necessary in order to make a QEF election and to report their shares of ordinary

DIRECTORS REPORTCORPORATE AND SHARE INFORMATION continued






earnings and net capital gains for each year for which CSR is a PFIC. CSR has had substantial taxable income in prior years, and may have taxable income in 2010 or any future year in which it is
a PFIC. As CSR historically has not made cash distributions with respect to its stock, US holders may be taxed on significant phantom income if they make a QEF election. A US holder may make a separate election to defer the payment
of taxes on undistributed income inclusions under the QEF rules, but any taxes deferred would be subject to an interest change. For any year for which CSR is not a PFIC, the QEF election would be inoperative. If US holders make a QEF election, they
would generally recognize capital gain or loss on the sale, exchange or other disposition of ordinary shares. The QEF election is made by each US holder, and can only be revoked with the consent of the IRS. US holders make the QEF election on IRS
Form 8621, which must be filed along with their tax return for the first taxable year to which the election will apply on or before the due date for such return (including extensions). US holders who decide to make the QEF election are advised to
make the election for the first taxable year for which CSR is a PFIC. A US holder also must file Form 8621 with the IRS for each subsequent year that the election is in effect. US holders cannot make both a mark-to-market election and a QEF election. US holders are urged to consult their own
tax advisors concerning the potential application of the PFIC rules to their ownership and disposition of ordinary shares, including the availability and advisability of making a mark-to-market or QEF election. Taxation of Dividends Subject to the PFIC rules described above, for
US federal income tax purposes, a US holder will generally include in gross income the amount of any dividend paid by CSR to the extent paid out of CSRs current and/or accumulated earnings and profits, as determined for US federal income tax
purposes, as ordinary income when the dividend is actually received by the US holder. Individual US holders currently are taxed at a maximum rate of 15% on dividends received from qualified foreign corporations, provided the US holders
satisfy certain holding period and other requirements. In order to be treated as a qualified foreign corporation, CSR must be eligible


for benefits of the United States income tax treaty with the United Kingdom. Although CSR believes that it is currently eligible for such treaty benefits, there can be no assurance that this will
be the case for any taxable year. Further, individual US holders will not be eligible for the reduced rates of dividend taxation if CSR is a PFIC for the taxable year of the dividend payment or the preceding taxable year. Corporate US holders will
be taxed on dividends received from CSR at a 35% tax rate. Dividends generally will be income from sources outside of the United States for foreign tax credit limitation purposes, and generally will not be eligible for the dividends-received
deduction that is allowed to US corporations in respect of dividends received from other US corporations. Distributions in excess of CSRs current and/or accumulated earnings and profits, as determined for US federal income tax purposes, will
be treated as a non-taxable return of capital to the extent of the US holders tax basis in the ordinary shares and thereafter as capital gain. The amount of the dividend includible in the income of a US holder will be the US dollar value of the dividend determined at the spot rate on the date that dividend is includible in the income of the US holder, regardless of whether the
payment is in fact converted into US dollars at such time. A US holder will have a basis in any GBP distributed by CSR equal to the US dollar value of the GBP on the date it is actually or constructively received by the US holder. Generally, any
gain or loss resulting from currency exchange fluctuations during the period from the date the dividend payment is includible in income to the date that payment is converted into US dollars will be treated as ordinary income or loss. Taxation of Capital Gains Subject to the PFIC rules described above,
upon a sale or other disposition of ordinary shares, a US holder will generally recognize gain or loss for US federal income tax purposes in an amount equal to the difference between the US dollar value of the amount realized and the US
holders tax basis, determined in US dollars, in the ordinary shares. Gain or loss recognized will be long-term capital gain or loss with respect to ordinary shares held for more than 12 months at the time of the sale or other disposition and
any gain recognized generally will be income from sources within the United States for foreign tax credit limitation purposes. The deductibility of capital losses is subject to significant limitations.

Backup Withholding and Information Reporting In general,
dividend payments with respect to ordinary shares and proceeds from the sale or other disposition of ordinary shares made (or deemed made) within the United States may be subject to information reporting to the IRS and US backup withholding
(currently at a rate of 28%). Backup withholding will generally not apply to a holder who:  ·

furnishes a correct taxpayer identification number and certifies, under penalties of perjury, that such holder is not subject to backup withholding on a Form
W-9, and otherwise complies with applicable requirements of the backup withholding rules;  ·

is a corporation or otherwise exempt from backup withholding and, when required, demonstrates this fact; or  ·

provides a certification of foreign status on Form W-8BEN or a successor form. Backup withholding is not an additional tax. Amounts withheld under the backup withholding rules will be allowed as a refund or credit against a holders US federal income tax liability, provided the holder
furnished the required information to the IRS. UK tax matters The following paragraphs summarise the material UK tax consequences for investors who are not resident in the UK for UK tax purposes (including US investors who are not resident in the UK for UK tax purposes)
regarding ownership and disposal of CSR ordinary shares. The following paragraphs, which are intended as a general guide only, are based on current UK
tax legislation and what is understood to be HM Revenue & Customs (the UK tax authority) practice (which are both subject to change at any time). They summarise certain limited aspects of the UK tax treatment of holders of CSR ordinary shares
and apply only to the position of holders of CSR ordinary shares who for UK tax purposes are beneficial owners of their CSR ordinary shares, hold their CSR ordinary shares as an investment (and not as assets to be realised in the course of a trade)
and are not treated as having acquired their CSR ordinary shares by reason of their


or anothers employment. The following paragraphs do not apply to individuals or companies that hold, directly or indirectly, 10% or more of the voting power in CSR. Holders of CSR ordinary
shares who are in any doubt as to their taxation position should consult an appropriate professional advisor immediately. Taxation of Dividends Under current UK taxation legislation, no tax will be withheld by CSR from cash dividend payments. Holders of CSR ordinary shares who are resident
outside of the UK will generally not receive any payment from HM Revenue & Customs in respect of any tax credit on dividends paid by CSR. Holders
of CSR ordinary shares who are not resident or, in the case of individuals, ordinarily resident, in the UK and who do not carry on a trade, profession, or vocation in the UK through a branch, agency or permanent establishment in connection with
which their CSR ordinary shares are held, used or acquired will not generally be liable to pay any UK tax in respect of any dividends received on their CSR ordinary shares. Holders of CSR ordinary shares who are resident or, in the case of
individuals, ordinarily resident, in the UK or who carry on a trade, profession or vocation in the UK through a branch, agency or permanent establishment in connection with which their CSR ordinary shares are held, used or acquired are encouraged to
consult appropriate professional advisors. Under its current dividend policy, CSR does not intend to pay a dividend for the foreseeable future. Any
future payment of dividends will be at the discretion of CSRs board of directors. Taxation of Capital Gains A holder of CSR ordinary shares will not ordinarily be liable for UK tax on capital gains realised on the disposal of CSR ordinary shares, unless, at the time of the
disposal, he or she carries on a trade, profession or vocation in the UK through a branch or agency (in the case of an individual shareholder) or a permanent establishment (in the case of a corporate shareholder) and those CSR ordinary shares are,
or have been, used, held or acquired for the purposes of that trade, profession or vocation or branch or agency or permanent establishment (as the case may be).

A holder of CSR ordinary shares who is an individual and who has ceased to be resident or ordinarily resident in the UK for UK tax purposes for a period
of less than five years of assessment and who disposes of all or part of his CSR ordinary shares during that period of temporary non-residence may be liable on his return to the UK to taxation on chargeable gains arising during the period of
absence, subject to any available exemption or relief. Stamp Duty and Stamp Duty Reserve Tax No UK stamp duty or UK stamp duty reserve tax (UK SDRT) will generally be payable on the issue of CSR ordinary shares. Subject to the paragraph below, where CSR ordinary shares are issued or transferred (i) to, or to a nominee or agent for, a person whose business is or includes the
provision of clearance services, or a Clearance Service, or (ii) to, or to a nominee or agent for, a person whose business is or includes issuing depositary receipts, or a Depositary Receipt System, UK stamp duty or UK SDRT will generally be payable
at the rate of 1.5% of the consideration paid (rounded up to the nearest multiple of £5 in the case of UK stamp duty). The UK stamp duty or UK SDRT will generally be paid by the Clearance Service or the Depositary Receipt System, as the case
may be, but will, in practice, generally be reimbursed by the relevant participant in the Clearance Service or the Depositary Receipt System. A Clearance Service can elect under section 97A of the Finance Act 1986, or Section 97A, provided certain
conditions are satisfied, for the normal rate of UK stamp duty or UK SDRT (generally no charge on issue and a charge at 0.5% of the amount or value of the consideration paid, rounded up to the nearest £5 in the case of UK stamp duty, on
transfer) to apply to issues or transfers of CSR ordinary shares into, and transactions within, such Clearance Service instead of the higher rate of 1.5% generally applying to an issue or transfer of CSR ordinary shares into the Clearance Service
and the ability to transfer CSR ordinary shares while in the Clearance Service without there being UK stamp duty or UK SDRT. Following a recent
decision of the European Court of Justice, HM Revenue & Customs have announced that they will not seek to apply the 1.5% UK SDRT charge where new shares are first issued into an


EU Clearance Service or an EU Depositary Receipt System. In light of that announcement, if would seem that, in the view of HM Revenue & Customs, the 1.5% UK SDRT charge will continue to
apply to (i) the transfer of existing shares to Clearance Services or Depositary Receipt Systems, in each case whether or not in the EU and (ii) the issue of new shares to non-EU Clearance Services or non-EU Depositary Receipt Systems. However, a
charge to UK SDRT at 1.5% on the issue of new shares to a non-EU Clearance Service or a non-EU Depositary Receipt System is arguably not consistent with the aforementioned decision of the European Court of Justice. No UK stamp duty or UK SDRT will generally be payable on the issue of CSR ordinary shares into CREST (the London Stock Exchanges paperless trading system), but,
subject to the paragraph above, UK SDRT will be payable to the extent that the CSR ordinary shares are issued to, or into the CREST account of, a Clearance Service or a nominee or agent for a Clearance Service which has not made an election in
relation to the CSR ordinary shares under Section 97A or to, or into the CREST account of, a Depositary Receipt System or a nominee or agent for a Depositary Receipt System. The UK stamp duty or UK SDRT will generally be paid by the Clearance
Service or the Depositary Receipt System, as the case may be, but will, in practice, generally be reimbursed by the relevant participant in the Clearance Service or the Depositary Receipt System. Subject to an exemption for certain low value transactions, the transfer on sale of CSR ordinary shares in certificated form, or a right to such shares, will
generally give rise to a liability, usually met by the purchaser, to ad valoremUK stamp duty at the rate of 0.5% (rounded up to the nearest multiple of £5) of the amount or value of the consideration paid. An agreement to transfer such
shares or a right to such shares which is or becomes unconditional will generally give rise to UK SDRT at the rate of 0.5% of the amount or value of the consideration paid, such UK SDRT generally being payable by the transferee or purchaser. The
liability to UK SDRT will generally be cancelled or any UK SDRT paid will be refunded if the agreement is completed by a duly stamped transfer within six years of either the date of the agreement or, if the agreement was conditional, the date when
the agreement became unconditional.

A transfer of CSR ordinary shares on a paperless basis through CREST will generally be subject to UK SDRT at the rate
of 0.5% of the amount or value of the consideration paid, which will be collected and accounted for to HM Revenue & Customs by CREST (such UK SDRT generally being borne by the transferee or purchaser). No UK stamp duty or UK SDRT will arise on a
transfer of CSR ordinary shares into CREST provided that, in the case of UK SDRT, the transfer is not for money or moneys worth.


Generally, a gift of CSR ordinary shares or a transfer of such shares from a nominee to the beneficial owner will
give rise to neither UK stamp duty nor UK SDRT. The above statements are intended only as a general guide to the current UK stamp duty and UK SDRT
position. Transfers to certain categories of person are not liable to UK stamp duty or UK SDRT and others may be liable at a higher rate.

GLOSSARY






AGPS:assisted GPS: an augmentation to GPS where the mobile phone network can provide the almanac and
ephemeris data. By using the mobile phone network, the GPS receiver does not need to decode data from the satellites, thus both speeding up acquisition of a fix and allowing fixes to be made in areas where GPS signals are too weak to allow decoding
of data but are nonetheless strong enough to be used to measure time of arrival (see also GPS) Android: Android is a software
platform for mobile devices based on a Linux kernel, initially developed by Google and later the Open Handset Alliance attach rate:represents
the rate of adoption of additional products or technologies on to the primary or hosting product baseband:describing that part of a
radio telecommunication system in which information is processed before modulating on to, or after demodulating off, a radio frequency (RF) carrier wave BiCMOS or Bi-polar CMOS:is a process which combines bipolar junction transistors on CMOS technology. The combination utilises the high speed, high gain and low output characteristics of the bipolar technology with the high density
logic gates of the CMOS technology. It has advantages for RF performance, reduced power consumption and low noise circuits bipolar:bipolar
refers to the enhancement of the conduction of current within a transistor that enables the control of a larger electrical current thereby providing an amplified signal bill of materials:a list of the individual parts (or material) which comprise a finished product and the cost of each of those individual parts


BlueCore:means the CSR family of single chip CMOS based (see below) Bluetooth solutions which integrate onto
one chip the Radio Frequency (RF), baseband and communications protocol stack Bluetooth:is an open wireless protocol for exchanging data over
short distances from fixed and mobile devices Bluetooth low energy or BTLE:is designed to work side-by-side with and complement Bluetooth. It
operates in 2.4 GHz ISM band. Devices using ultra low power Bluetooth will be smaller and more energy-efficient than their Bluetooth counterparts cellular:derives from cellphone and means a mobile phone or other device which communicates through a network of radio cells CMOS:Complementary Metal Oxide Semiconductor technology: a semiconductor process technology that uses planar transistors to make chips that consume relatively low power and permit a high level of
integration chip:short for a microchip; semiconductor device or integrated circuit co-exist/co-existence:means the ability of two systems to operate in parallel without interfering with the other connectivity:enabling two electronic devices to communicate with each other and transfer data (voice/audio/music/picture/word files) using radio waves Connectivity Centre:a term first promulgated by CSR in its application to wireless connectivity solutions; the Connectivity Centre brings together many aspects of short range wireless connectivity products
with excellent co-existence capable of operating concurrently without degradation in optimum performance of each of the individual functions


CSP:Chip-Scale Package: a semiconductor package which is as small as the semiconductor chip and is used for
small form factor applications such as mobile phones, PDAs and wireless devices design win:CSR records a design win when a product using one of
its ICs becomes Bluetooth qualified die:another word for chip: often used to refer to the chips whilst they are still an
integral part of the silicon wafer or where they have been cut from the wafer but are, as yet, unpackaged digital:the
representation of data by a series of bits or discrete values such as 0s and 1s EGPS:enhanced GPS: as the name suggests an enhancement to GPS
whereby measurements are made by the GPS receiver on the signals received from the mobile phone network which allow both fine time and frequency assistance to the GPS receiver. This further accelerates acquisition of a fix, as well as allowing, when
GPS signals are unavailable, fall-back to a fix made solely from the measurements made on the cellular network (see also GPS) ERP
System: Enterprise Resource Planning System is a company wide computer software system used to manage and co-ordinate internal and external resources. The system facilitates the flow and management of information to improve data sharing and
decision making using a computer network FM or FM Radio: is a radio wave broadcast technology that conveys sound  voice and music 
using a carrier wave which varies its frequency during transmission, producing high quality audio clarity and tone fabless:short for
fabricationless, a business model used in the semiconductor industry, where the

CAUTIONARY NOTE REGARDING FORWARD LOOKING STATEMENTS






This Annual Report does not
constitute an invitation to underwrite, subscribe for, or otherwise acquire or dispose of any CSR plc shares.

This Annual Report contains statements
that are forward looking statements in relation to the future financial and operating performance and outlook of CSR. These forward looking statements are made in reliance on the safe harbour provisions of the United States Private
Securities Litigation Reform Act of 1995. Forward looking statements can be identified by words such as believes, estimates, anticipates, expects, intends, may,
will, plans, should, may and other similar expressions, and include statements relating to, among other things, expected growth in 2010 and beyond, expected revenues, expected future design wins and
increase in market share, the expected incorporation of the our products in those of our customers, the expectation of volume shipments of our products, opportunities in our industry and our ability to take advantage of those opportunities, the
effect of our financial performance on our share price, the impact of government regulation, expected performance against adverse economic conditions, and other expectations and beliefs of our management.

All forward looking statements are based upon numerous assumptions regarding CSRs business strategies and the environment in which CSR will operate and
therefore involve a number of known and unknown risks, contingencies, uncertainties and other factors, many of which are beyond the control of CSR. Actual results and developments could differ materially from those expressed or implied by these
forward looking statements as a result of numerous risks and uncertainties. These risks and uncertainties include, but are not limited to:



| | · |  | a continuing or worsening economic downturn, which could reduce demand for consumer products;
| | - |  | ---------------------------------------------------------------------------------------------



| | · |  | risks associated with securing sufficient capacity from the third-parties that manufacture, assemble and test CSRs products and other risks relating to
CSRs fabless business model;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · |  | continuing or worsening declines in the average selling prices of CSRs products;
| | - |  | ---------------------------------------------------------------------------------



| | · |  | risks associated with existing or future litigation;
| | - |  | ----------------------------------------------------



| | · |  | costs associated with the development of new products in response to market demand;
| | - |  | -----------------------------------------------------------------------------------



| | · |  | errors or failures in the hardware or software components of CSRs products;
| | - |  | ----------------------------------------------------------------------------



| | · |  | risks associated with acquiring and protecting intellectual property;
| | - |  | ---------------------------------------------------------------------



| | · |  | risks relating to forecasting consumer demand for and market acceptance of CSRs products and the products that use CSRs products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| | · |  | the cyclicality of the semiconductor industry;
| | - |  | ----------------------------------------------



| | · |  | the potential for disruption in the supply of wafers or assembly or testing services due to changes in business conditions, natural disasters, terrorist
activities, public health concerns or other factors;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | · |  | CSRs ability to manage past and future acquisitions;
| | - |  | -----------------------------------------------------



| | · |  | CSRs ability to attract and retain key personnel, including engineers and technical personnel;
| | - |  | -----------------------------------------------------------------------------------------------



| | · |  | the difficulty in predicting future results; and
| | - |  | ------------------------------------------------



| | · |  | other risks and uncertainties discussed elsewhere in this Annual Report, including, without limitation, under the heading Risk Factors on pages 45 to
57.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------

Each forward looking statement speaks only as of the date hereof. CSR does not undertake to release publicly any updates or
revisions to any forward looking statements contained herein, otherwise than required by law.

Past performance is no guide to future performance and
persons needing advice should consult an independent financial adviser. This Annual Report has been drawn up and presented in accordance with and reliance upon applicable English company law and the liabilities of the directors in connection with
this report shall be subject to the limitations and restrictions provided by such law.
