but the greater the risk of losing money. It is based on past data, may change overtime and may not be a reliable indication of the future risk profile of the Fund. The

more). It also looks to outperform the FTSE All-Share Index (the “Index”) overrolling 3-year periods, after the deduction of charges.
n The Fund is actively managed, and invests at least 90% of its assets in shares ofcompanies listed on the London Stock Exchange; predominantly companies
domiciled in the UK, or which have significant UK business operations. There is
no restriction on size, but investment tends to focus on the larger companies.
n The Index is regarded as an appropriate performance measure of the UK stock
market, with over 600 companies currently included, and provides a suitabletarget benchmark against which Fund performance will be evaluated over time.
n The Investment Manager selects companies considered to have good prospects
for share price growth across different sectors, and typically invests in fewer than
80 companies, including some companies not within the Index.
n The Investment Manager also seeks to create a portfolio that compares
favourably against the Index over rolling 12-month periods, when assessed using
the Columbia Threadneedle ESG Materiality Rating model.
n This model (developed and owned by Columbia Threadneedle Investments)
analyses company data to assess how effectively material environmental, socialand governance (ESG) risks and opportunities are being managed. If sufficient
data is available, the combined results are expressed as a numerical rating toindicate how much exposure a company has to material ESG risks andopportunities in a particular industry.
n Whilst the Fund may still invest in companies that have poor ESG Materialityratings, at least 50% of the portfolio is invested in companies with strong ratings.
n The Investment Manager engages with companies with a view to influencing
management teams to address material ESG risks and improve their ESG
practices.
n Columbia Threadneedle Investments is a signatory to the Net Zero AssetManagers Initiative and has committed to an ambition to reach net zero
emissions by 2050 or sooner for a range of assets, including the Fund. As such,
the Investment Manager will proactively engage with companies to assist withprogressing this and may disinvest from those not meeting the minimum
standards.
n The Fund only invests in companies that follow good governance practices. It
does not invest in companies which derive revenue from industries or activities
above the thresholds shown: tobacco production (5%); nuclear weapons –indirect involvement (5%), conventional weapons – military, or civilian firearms(10%), and thermal coal – extraction or power generation (30%), providing acompany is not engaged in new coal projects.
n The Fund excludes companies that have direct involvement in nuclear orcontroversial weapons, and companies determined to have breachedinternational standards and principles.
n The Fund may invest in other securities, collective investment schemes(including funds managed by Columbia Threadneedle companies), money market
instruments, deposits, and cash. Derivatives may only be held with the aim of
reducing risk or managing the Fund more efficiently.
n Income from investments in the Fund will be added to the value of your shares.

n The Fund is rated 6 because historically it has shown a high level of volatility(how much the value of the Fund goes up and down).

n The lowest category does not mean a risk-free investment.
n The value of investments can fall as well as rise and investors might not get backthe sum originally invested.

n Where investments are in assets that are denominated in multiple currencies, orcurrencies other than your own, changes in exchange rates may affect the valueof the investments.
n The Fund may invest in derivatives (complex instruments linked to the rise andfall of the value of other assets) with the aim of reducing risk or minimising thecost of transactions. Such derivative transactions may benefit or negatively affectthe performance of the Fund. The Manager does not intend that such use ofderivatives will affect the overall risk profile of the Fund.
n The Fund applies a range of measures as part of its consideration of ESG
factors, including the exclusion of investments involved in certain industries and/or activities. This reduces the investable universe, and may impact theperformance of the Fund positively or negatively relative to a benchmark or otherfunds without such restrictions.
n The risks currently identified as applying to the Fund are set out in the "Risk
Factors" section of the Prospectus.
