**(each a "Fund" and, collectively, the "Funds")**

**Supplement dated May 27, 2026 to each Fund's Prospectus (the "Prospectus"), Summary Prospectus (the "Summary Prospectus") and Statement of Additional Information ("SAI"), each dated January 28, 2026**

Effective June 15, 2026 (the "Effective Date"), each Fund will be renamed as reflected in the following table:

| | |
|:---|:---|
| **Current Name** | **New Name** |
| First Foundation Fixed Income Fund | Fundamental Core Fixed Income Fund |
| First Foundation Total Return Fund | Fundamental Family Office Allocation Fund |

The name changes are the result of a rebranding effort made in connection with a recent corporate reorganization involving the Funds' investment sub-adviser, First Foundation Advisors. The name changes will not affect how the Funds are managed, and each Fund's investment objective, principal investment strategies, investment policies and ticker symbols will not change.
