The Fund invests primarily in a diversified
portfolio of equity securities with relatively smaller capitalizations as compared to the overall U.S. market. The
Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities
of small- and mid‑capitalization companies meeting the Adviser’s growth criteria. For
purposes of this policy, companies meeting the Adviser’s growth criteria are those companies with securities included in any one
of the following indexes: the MSCI ACWI IMI Growth, the Russell 3000® Growth
Index, and the Morningstar Global All‑Cap Growth TME. Also, for purposes of this policy, small- and mid‑capitalization
companies are those companies falling within the lowest 25% of the total U.S. equity market capitalization (excluding, for purposes of
this calculation, companies with market capitalizations of less than $10 million). As of June 30, 2026, there were approximately
3,109 companies within the lowest 25% of the total U.S. equity market capitalization (excluding companies with market capitalizations
of less than $10 million) with market capitalizations ranging from $10 million to $69.7 billion. Because the Fund’s definition of
small- and mid‑capitalization companies is dynamic, the limits on market capitalization will change with the markets.
The Fund may invest in any company and
industry and in any type of equity security with potential for capital appreciation. It invests in well-known and established companies
and in new and less-seasoned companies. The Fund’s investment policies emphasize investments in companies that are demonstrating
improving financial results and a favorable earnings outlook. The Fund may invest in foreign securities.
When selecting securities, the Adviser
typically seeks companies that have strong, experienced management teams, strong market positions, and the potential to support greater
than expected earnings growth rates. In making specific investment decisions for the Fund, the Adviser combines fundamental and quantitative
analysis in its stock selection process.
The Fund invests principally in equity
securities but may also invest in other types of securities. The Fund, at times, invests in shares of exchange-traded funds (“ETFs”)
in lieu of making direct investments in securities. ETFs may provide more efficient and economical exposure to the types of companies
and geographic locations in which the Fund seeks to invest than direct investments. The Fund may also invest up to 20% of its total assets
in rights and warrants.
The Fund may enter into derivatives transactions,
such as options, futures contracts, forwards and swaps to manage risk and to seek to generate additional returns. 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 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.
