**Supplement dated January 9, 2026** 

**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 Bond Index Fund, Nationwide International Index Fund, Nationwide Mid Cap Market Index Fund, Nationwide NYSE Arca Tech 100 Index Fund and Nationwide Small Cap Index Fund</u>**

Each of the Nationwide Bond Index Fund, Nationwide International Index Fund, Nationwide Mid Cap Market Index Fund, Nationwide NYSE Arca Tech 100 Index Fund and Nationwide Small Cap Index Fund (each a "Fund") is updating its diversification policy under the Investment Company Act of 1940, as amended. Under the revised policy, each Fund will continue to track its respective 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 its respective index.

**Shareholder approval will not be sought if a 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:

Each of the Index Funds intends to be diversified in approximately the same proportion as the index it seeks to track (the "Index") is diversified. An Index 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 applicable Index. Shareholder approval will not be sought if an Index 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 applicable Index.

**PLEASE RETAIN THIS SUPPLEMENT FOR FUTURE REFERENCE**
