[1] The investment adviser is currently waiving a portion of its management fee. This waiver will be in effect through at least November 1, 2026. The adviser may elect at its discretion to extend, modify or terminate the waiver at that time; provided, however, that if fund shareholders approve a new management fee structure at a special meeting of shareholders to be held on November 25, 2025, the waiver will be in effect until the new management fee structure is implemented.
