*Effective immediately, the "Performance" section of the Prospectus is deleted in its entirety and replaced with the following:* 

 

**<u>Performance</u>**

On January 30, 2026, the Fund will acquire all of the assets and liabilities of the Optima Strategic Credit Fund (the "Predecessor Fund"), a series of The RBB Fund, Inc. (the "Reorganization"). As a result of the Reorganization, the Fund will adopt the accounting and performance history of the Predecessor Fund. Performance results shown in the bar chart and the performance table below reflect the performance of the Predecessor Fund.

The bar chart and table provide an indication of the risks of investing in the Predecessor 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 periods ended December 31, 2025, compare with those of the Bloomberg U.S. Universal Total Return Index, a broad-based market index, the iBoxx USD Liquid HY Index, and Markit CDX.NA.HY 5Y Long Total Return Index. Performance for Investor Class Shares is not shown because Investor Class Shares of the Fund had not commenced operations as of the date of this prospectus. The Fund's performance information is accessible on the Fund's website at funddocs.filepoint.com/optima/ or by calling the Fund at 1-877-341-4585. The Predecessor Fund's past performance before and after taxes is not necessarily an indication of how the Fund will perform in the future.

The index consists of liquid U.S. dollar denominated high yield bonds.
