The Fund considers a company to be a small-cap company if, at the time of purchase, the company has a market capitalization less than $2 billion. The Fund may invest a significant portion of its assets in common stocks of micro-capitalization (“micro-cap”) companies with market capitalizations less than $250 million at the time of purchase. Under normal market conditions, the weighted average market capitalization of the Fund’s portfolio will be less than that of the Russell 2000 Growth Index, and sector weights are limited to no more than two times that of the benchmark for sectors representing 15% or more of the Russell 2000 Growth Index. The Fund anticipates that such sectors may include consumer discretionary, information technology, healthcare, industrials, energy and/or financials. The largest company in the Russell 2000 Growth Index has a market capitalization of approximately $4.8 billion. The Fund will not exclusively invest in companies represented in the Russell 2000 Growth Index and such investments may constitute substantially less than 80% of the Fund’s assets. The Fund may invest up to 25% of its assets in foreign securities (including American Depositary Receipts (“ADRs”)) that are listed in the United States on a national securities exchange. In deciding which securities to buy, hold or sell for the Fund, the Adviser seeks to invest in innovative companies with strong business models, the financial resources to execute on their business plan and the potential for significant top line growth. The Adviser’s process combines bottom-up fundamental research with a thematic approach. The Adviser’s fundamental research is an exhaustive assessment of five broad factors: (1) market opportunity and competitive positioning; (2) business model; (3) financial position; (4) management; and (5) valuation. The Adviser aims to identify small-cap companies early in the growth curve before they are appreciated by the broader market and whose stocks can appreciate regardless of the current operating environment. The Adviser employs a theme-based approach when exploring new investment opportunities. The Adviser attempts to identify current trends and changes within specific industries that might prove beneficial to a number of companies and it is common for the Adviser to invest in multiple companies along this one common theme. Themes are often based on disruptive events, new technologies, changing regulations, cultural and behavioral changes, and industry cycles. Once a theme is identified, the Adviser seeks to identify not only the primary beneficiaries of the theme, but secondary and tertiary beneficiaries as well. As a result, themes can ultimately be comprised of companies in several industries within multiple sectors. The core tenet of thematic investing is owning multiple companies that stand to benefit from the same trend and/or economic tailwind. Identifying a variety of companies poised to enjoy improving fundamentals is the primary advantage of a theme-based approach. Thematic investing also aims to reduce the company-specific risks inherent in small-cap investing. The Adviser believes this approach leads to ideas earlier than they can be identified through quantitative screening. Additionally, the Adviser believes its thematic approach leads to a portfolio that emphasizes the growth areas of the economy. Importantly, while themes are an excellent source of new ideas, investments are made solely on the fundamental merits of the individual company. The Fund will typically hold shares of stock in 90 to 120 companies, with no single company exceeding 5% of the Fund’s portfolio at the time of purchase. Generally, the Adviser will sell a company’s stock when the price approaches the Adviser’s estimate of economic value or when the fundamentals of the company have deteriorated. The Adviser also may sell if changing circumstances alter its assessment of the company’s economic value or if more attractive alternatives are identified. Please be aware that you may lose money by investing in the Fund. The following is a summary description of the principal risks of investing in the Fund. General Market Risk. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities. You could lose money on your investment in the Fund, or the Fund could underperform other investments. Management Risk. The Adviser’s investment strategies for the Fund may not result in an increase in the value of your investment or in overall performance equal to other investments. Additionally, while the Adviser has been managing assets for investors since 2004, the Adviser has not previously managed a registered mutual fund. Limited History of Operations. The Fund is a recently formed mutual fund and there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board may determine to liquidate the Fund. Common Stock Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Common stock is generally subject to greater risk than preferred stocks and debt obligations because holders of common stock generally have inferior rights to receive payments from issuers in comparison with the rights of the holders of other securities, bondholders and other creditors. Small-Cap and Micro-Cap Companies Risk. Investments in small-cap and micro-cap companies entail greater risks than those associated with larger, more established companies, including greater volatility and less liquidity. Generally, the smaller the company size, the greater the risks. Growth-Style Investing Risk. Because the Fund focuses on growth-style stocks, its performance may at times be better or worse than the performance of funds that focus on other types of stocks or that have a broader investment style. Growth stocks are often characterized by high price-to-earnings ratios, which may be more volatile than stocks with lower price-to-earnings ratios. Sector Concentration Risk. Because the Fund may have sector weights representing up to two times that of the benchmark for sectors representing 15% of more of the Russell 2000 Growth Index, the Fund may be subject to the risks affecting that one sector, including the risk that the securities of companies within that one sector will underperform due to adverse economic conditions, regulatory or legislative changes or increased competition affecting the sector, more than would a fund that invests in a wide variety of market sectors. Foreign Securities Risk. The Adviser may invest in foreign securities and ADRs relating to foreign securities. Investments in foreign financial markets present political, regulatory and economic risks which are significant and which may differ in kind and degree from the risks presented by investments in the U.S. financial markets. These may include changes in foreign currency exchange rates or controls, greater price volatility, differences in accounting standards and policies and in the type and nature of disclosures required to be provided by foreign issuers, substantially less liquidity, controls on foreign investment and limitations on repatriation of invested capital.

Under current market conditions, the Fund considers a company to be a small-cap company if it has a total market capitalization at the time of purchase of $100 million to the higher of $3 billion or the high end of the range of companies represented in the Russell 2000 Value Index. The largest company in the Russell 2000 Value Index has a market capitalization of approximately $4.8 billion. The Fund will not exclusively invest in companies represented in the Russell 2000 Value Index and such investments may constitute substantially less than 80% of the Fund’s assets. The Fund may invest up to 25% of its assets in foreign securities (including American Depositary Receipts (“ADRs”)) that are listed in the United States on a national securities exchange. In deciding which securities to buy, hold or sell, the Adviser pursues a value oriented approach that seeks to identify securities whose market value is less than their intrinsic value. The Adviser focuses on securities with market-to-book ratios and price-to-earnings ratios that are lower than those of the general market averages or similar companies. The Adviser also may consider a company’s dividend yield, growth in sales, balance sheet, management capabilities, earnings and cash flow, as well as other factors. In addition, the Adviser may select securities because it believes there is some potential catalyst to cause a company’s stock price to rise.

Common Stock Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Common stock is generally subject to greater risk than preferred stocks and debt obligations because holders of common stock generally have inferior rights to receive payments from issuers in comparison with the rights of the holders of other securities, bondholders and other creditors. Small-Cap Companies Risk. Investments in small-cap companies entail greater risks than those associated with larger, more established companies, including greater volatility and less liquidity. Value-Style Investing Risk. Because the Fund focuses on value-style stocks, its performance may at times be better or worse than the performance of funds that focus on other types of stocks or that have a broader investment style. Value-style stocks tend to be inexpensive relative to their earnings or assets compared to other types of stocks, but may not ever realize their full value. Foreign Securities Risk. The Adviser may invest in foreign securities and ADRs relating to foreign securities. Investments in foreign financial markets present political, regulatory and economic risks which are significant and which may differ in kind and degree from the risks presented by investments in the U.S. financial markets. These may include changes in foreign currency exchange rates or controls, greater price volatility, differences in accounting standards and policies and in the type and nature of disclosures required to be provided by foreign issuers, substantially less liquidity, controls on foreign investment and limitations on repatriation of invested capital.
