## Questions

### Who runs investment decisions at Thomas S Fund Adviser?

Thomas S. White Jr. serves as the sole portfolio manager and has led the strategy since its 1995 launch. He is supported by a small, unnamed research team. No co-manager or deputy portfolio manager has been disclosed in public regulatory filings.

### How does the firm source investment ideas for its international small-cap portfolio?

The process begins with a quantitative screen across a universe of roughly 6,000 non-US companies, filtering for persistent earnings growth, strong returns on invested capital, and low financial leverage. Survivors undergo fundamental analysis that includes management interviews and competitive-position assessment. The portfolio is deliberately concentrated to reflect the screen's conviction output rather than index weights.

### What is the firm's relationship to GW&K Investment Management?

The 'GW&K' in the fund's name refers to a different Boston-based investment manager. Thomas S Fund Adviser is an independent sub-adviser to the AMG GW&K International Small Cap Fund. GW&K Investment Management, a separate entity, serves as another sub-adviser to the same fund. The two firms are not legally or operationally linked.

### What geographic regions does the fund invest in?

The fund invests in non-US developed and emerging markets, with consistent exposure to Western Europe, Japan, Scandinavia, and, to a lesser extent, select emerging markets in Asia and Latin America. The portfolio avoids any single-country concentration.

### Is there a disclosed succession plan for the portfolio manager?

No succession plan or named successor has been disclosed in the fund's prospectus, statement of additional information, or any public communication as of mid-2026. This is the most prominent operational risk for allocators evaluating the strategy.

### Does the firm manage any other strategies or vehicles?

As of mid-2026, the firm's sole public mandate is the AMG GW&K International Small Cap Fund. A UCITS version of the strategy launched in 2024, for which Thomas S Fund Adviser also acts as co-sub-adviser, but no additional distinct strategies are offered.
