Supplement dated March 16, 2026 to
the Summary Prospectus and the Prospectus for Institutional Investors (“Prospectus”), each dated February 28, 2026, for International Developed Markets Equity Portfolio
This Supplement contains new and additional information and should be read in connection with your Summary Prospectus and Prospectus
Dear Shareholder,
Please be advised that the Harding Loevner International Developed Markets Equity Portfolio (the “IDME Mutual Fund”) is entering into a transaction with a newly-created shell series of the Fund, the Harding Loevner International Developed Markets Select Equity ETF (the “IDME ETF”) in order to convert the IDME Mutual Fund into an exchange-traded fund (“ETF”) (the “Transaction”).
The Transaction is expected to be completed after the close of business on July 17, 2026 (or at such other date as agreed to by the parties to the Transaction) (the “Closing Date”).
If you are an existing shareholder and your account can hold shares of an ETF, you will become a shareholder of the IDME ETF after the close of business on the Closing Date without any action by you.
If you hold shares of the IDME Mutual Fund in an account that cannot hold shares of an ETF (i.e., your account is not permitted to purchase securities traded in the stock market), you may receive cash, which may be a taxable event for you, or there are certain actions you can take, as further described below.
The IDME ETF will have identical investment objectives, strategies and policies to those of the IDME Mutual Fund.
Completion of the Transaction is subject to making various filings with the U.S. Securities and Exchange Commission (the “SEC”) and a number of conditions under an Agreement and Plan of Reorganization and Liquidation between the IDME Mutual Fund and the IDME ETF (the “Plan”) approved by the Board of Directors (the “Board”) of the Fund. The Transaction does not require shareholder approval.
An Information Statement/Prospectus with respect to the Transaction is expected to be mailed to IDME Mutual Fund shareholders in May 2026. The Information Statement/Prospectus will describe in detail both the Transaction and the IDME ETF, as well as other matters. Investors may obtain a free copy of the Prospectus of the IDME ETF once the registration statement of the IDME ETF becomes effective at
http://www.hardingloevnerfunds.com or by calling (877) 435-8105.
The remainder of this Supplement is intended to provide you with further detail about the Transaction.
We thank you for your investment in the Fund...
