Important Information Regarding Aberdeen International Sustainable Leaders Fund, Aberdeen Global Equity Impact Fund and Aberdeen Global High Income Fund

Dear Valued Shareholder,

Thank you for being an investor in Aberdeen International Sustainable Leaders Fund, Aberdeen Global Equity Impact Fund, and/or Aberdeen Global High Income Fund. Yesterday we adjourned the Special Meeting of Shareholders of the Funds to October 18, 2021 to provide shareholders who have not yet cast their important proxy vote with additional time to do so.  Our records indicate that we do not yet have your proxy voting instructions.  Please help us by casting your vote as soon as possible.

As discussed in the proxy statement/prospectus previously sent to you, this special meeting has been called to vote on a proposal to reorganize each of these three funds. Aberdeen Standard Investments Inc., the investment adviser to the Target Funds and the Acquiring Funds has informed the Board that each Reorganization would allow shareholders to benefit from economies of scale able to be realized by being shareholders of the Acquiring Funds, which are series within a larger trust with common service providers and certain shared trust-wide expenses. For the reasons summarized in the proxy statement/prospectus, the Board of Trustees of Aberdeen Investment Funds unanimously recommends that you consider voting FOR the Reorganization(s).

Please help us by casting your proxy vote today.

For more information, please refer to the proxy statement, which can be found at https://vote.proxyonline.com/aberdeen/docs/abrdnspecial2021.pdf .  If you have any proxy related questions, or would like to cast your proxy vote by phone, please call (800) 431-9643 for assistance. Representatives are available Monday through Friday 9 a.m. to 10 p.m. Eastern Time.  We very much appreciate your attention to this matter. Please help us by casting your vote today!

Sincerely,

Ben Moser, Head of Investor Services

Aberdeen Investment Funds
