Notice to Shareholders of the sub-fund CT (Lux) SDG Engagement Global Equity (the “Portfolio”)
Luxembourg, 8 November 2023
Dear Shareholder,
Change in comparator benchmark for the Portfolio and definition of “mid-capitalisation companies”
As you are an investor in the Portfolio, we are writing to let you know that the board of directors of theFund (the “Board”) is making changes to the Portfolio, with effect from 29 December 2023 (the “EffectiveDate”).
What is changing?
The description of the Portfolio’s investment objective and policy is being amended to (i) reflect thechange of the comparator benchmark from the MSCI ACWI SMID Index to MSCI ACWI Mid Cap Index (the“Benchmark”), (ii) remove the reference to small capitalisation companies and (iii) define “midcapitalisation companies” as companies globally that are smaller by market capitalisation than the largest
constituent of the Benchmark and that are larger by market capitalisation than the smallest constituentof the Benchmark.
Why are we making the change?
The decision to change the Portfolio’s benchmark follows a review by Columbia Threadneedle
Management Limited (the “Investment Manager”) who undertook a comprehensive comparison of thePortfolio with the current benchmark and the alternative.
Following the review, it was clear that the MSCI ACWI Mid Cap Index was more reflective of the current
make-up of the Portfolio and a more suitable comparator benchmark for the Portfolio. In addition, it wasagreed that the Portfolio is tilted towards “Mid-Cap companies” compared with the current Small andMid-Cap Index (MSCI ACWI SMID) and that a change to a Mid-Cap Index (MSCI ACWI Mid Cap Index) would
improve portfolio alignment by market capitalisation, on a global basis. Since MSCI constructs theBenchmark on a country-by-country basis (rather than by market capitalisation), it was decided to include
a definition allowing to establish the market capitalisation window using the index capitalisation of theBenchmark.

How will this affect my investment?
Your investment will not be affected. The Investment Manager will continue to actively manage thePortfolio in the same way. The Portfolio is not constrained by the Benchmark and the Investment Manager
will continue to have significant freedom to invest in a portfolio that is materially different to thecomposition of the Benchmark.
What do I need to do?
You do not need to do anything as a result of this change, which will take effect automatically on theEffective Date.
What can I do if I disagree with the changes?
Your right to redeem or convert your shares in the Portfolio is not affected and you can continue to do
this without any charges in accordance with the Fund’s prospectus (the “Prospectus”).
We are unable to provide financial or tax advice and we therefore suggest that you seek professional
advice about potential tax implications.
All capitalised terms in this notice not otherwise defined, have the same meaning as in the Prospectus.
A copy of the Prospectus reflecting the above is available, free of charge, at the Fund’s registered office
and from the Investment Manager.
