**Supplement dated November 6, 2025** 

**to the Statement of Additional Information ("SAI") dated February 28, 2025** 

*Capitalized terms and certain other terms used in this supplement, unless otherwise defined in this supplement, have the meanings assigned to them in the SAI.* 

**<u>Nationwide S&P 500 Index Fund</u>**

The Nationwide S&P 500 Index Fund (the "Fund") is updating its diversification policy under the Investment Company Act of 1940, as amended. Under the revised policy, the Fund will continue to track the S&P 500 Index (the "Index") even if the Fund operates as nondiversified as a result of a change in relative market capitalization or index weighting of one or more constituents of the Index.

**Shareholder approval will not be sought if the Fund crosses from diversified to nondiversified status under such circumstances.** 

Effective immediately, the SAI is amended as follows:

1. The following is added to the "Investment Restrictions" section:

The Nationwide S&P 500 Index Fund (the "Fund") intends to be diversified in approximately the same proportion as the S&P 500 Index (the "Index") is diversified. The Fund may become nondiversified, as defined in the 1940 Act, solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Index. Shareholder approval will not be sought if the Fund crosses from diversified to nondiversified status due solely to a change in the relative market capitalization or index weighting of one or more constituents of the Index.
