The Fund invests primarily in a diversified
portfolio of equity securities of mid‑capitalization U.S. companies. The
Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in securities of
mid‑capitalization companies meeting the Adviser’s value criteria. For
purposes of this policy, companies meeting the Adviser’s value criteria are those companies with securities included in any one
of the following indexes: the MSCI ACWI IMI Value, the Russell 3000® Value
Index, the MSCI ACWI IMI Value Weighted, and the Morningstar Global All‑Cap Value TME. Also, for purposes of this policy, mid‑capitalization
companies are those companies falling within the market capitalization range of companies in the Russell Midcap®
Index. As of June 30, 2026, the market capitalization of companies in the Russell Midcap®
Index ranged from approximately $607.5 million to $88.2 billion. Because the Fund’s definition of mid‑capitalization companies
is dynamic, the lower and upper limits on market capitalization will change with the markets.
The Fund invests in companies that are
determined by the Adviser to be undervalued, using the Adviser’s fundamental value approach. In selecting securities for the Fund’s
portfolio, the Adviser uses its fundamental and quantitative research to identify companies whose long-term earnings power is not reflected
in the current market price of their securities.
In selecting securities for the Fund’s
portfolio, the Adviser seeks companies with attractive valuation and compelling success factors. The Adviser then uses this information
to calculate an expected return. Returns and rankings are updated on a daily basis. The rankings are used to determine prospective candidates
for further fundamental research and, subsequently, possible addition to the portfolio.
The Adviser typically projects a company’s
financial performance over a full economic cycle within the context of forecasts for real economic growth, inflation and interest rate
changes. The Adviser focuses on the valuation implied by the current price, relative to the earnings the company will be generating five
years from now, or “normalized” earnings, assuming average mid‑economic cycle growth for the fifth year.
The Fund’s management team and
other senior investment professionals work in close collaboration to weigh each investment opportunity identified by the research staff
relative to the entire portfolio and determine the timing and position size for purchases and sales. Analysts remain responsible for monitoring
new developments that would affect the securities they cover. The team will generally sell a security when it no longer meets appropriate
valuation criteria, although sales may be delayed when positive return trends are favorable.
The Adviser seeks to manage overall portfolio
volatility relative to the Russell Midcap Value® Index by favoring promising
securities that offer the best balance between return and targeted risk. At times, the Fund may favor or disfavor a particular sector
compared to that universe of companies. The Fund may invest significantly in companies involved in certain sectors that constitute a material
portion of the universe of mid‑capitalization companies, such as industrials and consumer services.
The Fund may enter into derivatives transactions,
such as options, futures contracts, forwards, and swaps. The Fund may use options strategies involving the purchase and/or writing of
various combinations of call and/or put options, including on individual securities and stock indices, futures contracts (including futures
contracts on individual securities and stock indices) or shares of exchange-traded funds (“ETFs”). These transactions may
be used, for example, in an effort to earn extra income, to adjust exposure to individual securities or markets, or to protect all or
a portion of the Fund’s portfolio from a decline in value, sometimes within certain ranges.
The Fund may invest in securities issued
by non‑U.S. companies.
The Fund may, at times, invest in shares
of ETFs in lieu of making direct investments in equity securities. ETFs may provide more efficient and economical exposure to the type
of companies and geographic locations in which the Fund seeks to invest than direct investments.
