The following bar chart and table provide some indication of the risks of investing in Small Cap Fund by showing changes in Small Cap Fund’s performance over time. The tables also compare Small Cap Fund’s performance to a broad measure of market performance that reflects the type of securities in which Small Cap Fund invests.

A Note on Performance

 

Ordinary Shares and Institutional Shares commenced operations on August 3, 1992, and January 6, 1993, respectively. R6 Shares commenced operations on October 31, 2024. Performance information for R6 Shares will be available after the share class has been offered for a full calendar year. Returns for R6 Shares would have been substantially similar to the returns of Institutional Shares because each share class is invested in the same portfolio of securities, and returns would differ only to the extent that expenses of the classes are different. Prior to January 1, 2015, Small Cap Fund had a different sub-adviser and pursued a different principal investment strategy.

While the Environmental Opportunities Fund’s investment objective, principal investment strategies, and risks are identical to fund’s predecessor (the “Predecessor Fund”) and theoretically would have invested in the same portfolio of securities, the Environmental Opportunities Fund’s performance may be different than the performance of the Predecessor Fund due to, among other things, differences in fees and expenses.

 

The bar chart and table that follow provide some indication of the risks of investing in the Environmental Opportunities Fund by showing changes in the Predecessor Fund’s performance from year to year and by showing how the Predecessor Fund’s average annual total returns for one year and since inception compare with those of a broad-based securities market index. How the Predecessor Fund has performed in the past (before and after taxes) is not necessarily an indication of how the Environmental Opportunities Fund will perform in the future. Updated performance information is available at www.peartreefunds.com.

 

Performance information shown prior to the close of business on August 31, 2021 is that of the Predecessor Fund. Accordingly, the returns of the Ordinary Shares in the bar chart and table are the returns of the Predecessor Fund’s Investor Class. Returns of the Institutional Shares shown in the table below reflect the returns of the Predecessor Fund’s Institutional Class.
