(1) The Manager, in its capacity as
transfer agent, has contractually agreed until July 31, 2026 to waive such portion of the fees that it would otherwise receive for serving
as transfer agent such that the aggregate transfer agent fee with respect to Institutional Shares would be calculated using an annual
rate of 0.04 percent of the net assets of the Fund attributable to Institutional Shares. This fee waiver does not apply to Ordinary Shares
or R6 Shares. This fee waiver agreement only may be terminated with the consent of the Trustees. The Manager does not have the right
to recoup from Environmental Opportunities Fund amounts that it has waived under that agreement.

(2) The Manager has contractually
agreed until July 31, 2026 to reimburse such portion of the expenses of the Fund attributable to Ordinary Shares such that "Total
Annual Fund Operating Expenses after Fee Waiver and/or Expense Reimbursement" with respect to Ordinary Shares, Institutional Shares
and R6 Shares, excluding AFFE and extraordinary expenses, is not greater than 1.24 percent of the Fund's net assets attributable
to Ordinary Shares, 0.99 percent of the Fund's net assets attributable to Institutional Shares, and 0.95 percent of the Fund's
net assets attributable to R6 Shares.

**Example**

This example is intended to help you compare the cost of investing in Environmental Opportunities Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in Environmental Opportunities Fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5 percent return each year and that Environmental Opportunities Fund's operating expenses remain the same as set forth in the table above. The example also assumes that the fee waiver and expense reimbursement agreements currently in effect expire July 31, 2026; therefore, amounts for 3-, 5- and 10-year periods do not include any adjustment to reflect any fee waivers or expense reimbursements. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **1 year** | **3 years** | **5 years** | **10 years** |
| Ordinary Shares | $126 | $459 | $815 | $1819 |
| Institutional Shares | $101 | $379 | $679 | $1530 |
| R6 Shares | $97 | $343 | $609 | $1369 |

---

\*&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\*&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\*

The rest of the Prospectus and Statement of Additional Information remain unchanged.
