Strategy. To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of mid-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell Midcap Index at the time of initial purchase. Although the Fund invests primarily in domestic securities, it may also invest in securities of foreign companies. The Funds strategy utilizes a qualitative, bottom-up research driven approach to identify companies that the Portfolio Managers believe have catalysts for growth which are underappreciated by the market.

Although the Fund invests primarily in domestic securities, it may also invest in securities of foreign companies. The Funds strategy utilizes a qualitative, bottom-up research driven approach to identify companies that the Portfolio Managers believe have catalysts for growth which are underappreciated by the market. The Portfolio Managers seek to invest in underappreciated companies with the following characteristics: durable and potentially unique business models and/or proficient management capable of advancing the development of and/or strengthening of sustainable and consistent revenue growth, cash flow growth, earnings growth and/or overall balance sheet strength. Such catalysts may include a new technology, product or service, a regulatory update, market share gains, cyclical inflections (e.g. companies whose returns are driven by macro-economic factors), corporate restructurings or self-help initiatives (e.g. internal operating efforts to increase company efficiencies). The Portfolio Managers may also invest in anticipation of a catalyst. In analyzing catalysts, the Portfolio Managers evaluate each catalysts uniqueness, timing, growth potential and sustainability, as well as assessing execution risks, competitive barriers and threats. The Portfolio Managers are also attempting to exploit market inefficiencies that potentially may exist within the small-to-mid-capitalization market, due to the number of companies that comprise the investable universe and the limited amount of available research that exists for some of those companies. Investable companies emerging from the Portfolio Managers bottom-up fundamental, qualitative and valuation analysis fall into the following investment classifications: Core investments: are typically more mature companies, engaged with, and participating in, compelling secular growth trends, that the Portfolio Managers believe offer a demonstrated history of consistent execution and results. These tend to represent multi-year holdings of the strategy. Turn investments: represent holdings in a wide range of corporate development and maturity stages and are generally driven by what the Portfolio Managers believe to be a distinct developing catalyst, such as a new product or service, market share gains or internal corporate self-help opportunities to improve operating efficiencies. Tactical investments: represent holdings with a shorter-term investment horizon due to catalysts the Portfolio Managers believe are typically associated with cyclical trends and opportunities, a disconnect with market expectations providing an opportunity on valuation or a new product, or financial or regulatory developments that could have a material impact on the company. Tactical investments have the potential to grow into Turn investments, while compelling Turn investments will ideally develop into Core investments. The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends. The Portfolio Managers constantly monitor their holdings and are focused on maintaining what they believe is an appropriate and attractive risk/reward balance with a disciplined sell process that acts quickly and dispassionately to address both positive and negative outcomes. A position is typically trimmed or exited for the following reasons: to harvest gains from significant short-term price appreciation, the positive realization of a catalyst, the achievement of a price target or elevated valuations, identification of a better idea, to minimize potential risks, to address an absence of near-term drivers or catalysts, a significant deterioration of fundamentals, a change in management or operating strategy or the failure of a catalyst to develop. The Fund will not change its strategy of normally investing at least 80% of its net assets in mid-capitalization companies, without providing shareholders at least 60 days notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
