Growth Fund




The Board has structured itself in a manner that it believes allows it to effectively perform its oversight function.

The Board of Trustees is composed of six Independent Trustees and one Trustee who is an “interested person” of the Trust (the “Interested Trustee”).

Dr. Michael D. Akers
Mr. Gary A. Drska
Vincent P. Lyles
Erik K. Olstein
Lisa Zúñiga Ramírez
Gregory M. Wesley
John P. Buckel, Interested Trustee

Accordingly, 85% of the members of the Board are Independent Trustees, Trustees who are not affiliated with the Adviser or its affiliates, or any other investment adviser or other service provider to the Trust or any underlying fund. The Board of Trustees has established three standing committees, an Audit Committee, a Nominating Committee and a Valuation Committee. Each of the Audit Committee and the Nominating Committee is comprised entirely of Independent Trustees. The Independent Trustees have engaged their own independent counsel to advise them on matters relating to their responsibilities in connection with the Trust. More information is available in the Statement of Additional Information (SAI).


All investments have risks. The Fund is designed for long-term investors. Equity investments are subject to market fluctuations and the Fund’s share price can fall because of weakness in the broad market, a particular industry or specific holdings. Investments in small and mid-cap companies generally are more volatile. International investing risks include among others political, social or economic instability, difficulty in predicting international trade patterns, taxation, and foreign trading practices and greater fluctuations in price than U.S. corporations. The Fund may invest in initial public offerings by small cap companies, which can involve greater risks than investments in companies which are already publicly traded.

About Morningstar

Morningstar Small Blend Category, as defined by Morningstar are stocks in the bottom 10% of the capitalization of the U.S. equity market are defined as small cap. The blend style is assigned to portfolios where neither growth nor value characteristics predominate.

The Morningstar Rating™ for funds, or “star rating”, is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed- end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product’s monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The Morningstar Rating does not include any adjustment for sales loads. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. Past performance is no guarantee of future results.

The Morningstar Medalist RatingTM is the summary expression of Morningstar’s forward-looking analysis of investment strategies as offered via specific vehicles using a rating scale of Gold, Silver, Bronze, Neutral, and Negative. The Medalist Ratings indicate which investments Morningstar believes are likely to outperform a relevant index or peer group average on a risk-adjusted basis over time. Investment products are evaluated on three key pillars (People, Parent, and Process) which, when coupled with a fee assessment, forms the basis for Morningstar’s conviction in those products’ investment merits and determines the Medalist Rating they’re assigned. Pillar ratings take the form of Low, Below Average, Average, Above Average, and High. Pillars may be evaluated via an analyst’s qualitative assessment (either directly to a vehicle the analyst covers or indirectly when the pillar ratings of a covered vehicle are mapped to a related uncovered vehicle) or using algorithmic techniques. Vehicles are sorted by their expected performance into rating groups defined by their Morningstar Category and their active or passive status. When analysts directly cover a vehicle, they assign the three pillar ratings based on their qualitative assessment, subject to the oversight of the Analyst Rating Committee, and monitor and reevaluate them at least every 14 months. When the vehicles are covered either indirectly by analysts or by algorithm, the ratings are assigned monthly. For more detailed information about these ratings, including their methodology, please go to

The Morningstar Medalist Ratings are not statements of fact, nor are they credit or risk ratings. The Morningstar Medalist Rating (i) should not be used as the sole basis in evaluating an investment product, (ii) involves unknown risks and uncertainties which may cause expectations not to occur or to differ significantly from what was expected, (iii) are not guaranteed to be based on complete or accurate assumptions or models when determined algorithmically, (iv) involve the risk that the return target will not be met due to such things as unforeseen changes in management, technology, economic development, interest rate development, operating and/or material costs, competitive pressure, supervisory law, exchange rate, tax rates, exchange rate changes, and/or changes in political and social conditions, and (v) should not be considered an offer or solicitation to buy or sell the investment product. A change in the fundamental factors  underlying the Morningstar Medalist Rating can mean that the rating is subsequently no longer accurate.
