A higher portfolio turnover rate &lt;br /&gt;may indicate higher transaction costs and may result in higher taxes when Fund&lt;br /&gt;shares are held in a taxable account. These transaction costs, and potentially&lt;br /&gt;higher taxes, which are not reflected in the annual fund operating expenses, or&lt;br /&gt;in the Example, affect the Fund&apos;s performance.

The Fund considers mid-cap&lt;br /&gt;companies to be companies with market capitalizations of approximately $1&lt;br /&gt;billion to $10 billion and large-cap companies to be companies with market&lt;br /&gt;capitalizations greater than $10 billion. The Fund may also purchase securities&lt;br /&gt;with an equity component, such as preferred stock, warrants, rights or other&lt;br /&gt;securities that are convertible into or exchangeable for shares of common&lt;br /&gt;stock. The Fund may invest up to 25% of its net assets in foreign securities,&lt;br /&gt;and will normally make such investments through the purchase of American&lt;br /&gt;Depositary Receipts ("ADRs").&lt;br /&gt; &lt;br /&gt;The Fund takes a conservative approach to growth stock investing that emphasizes&lt;br /&gt;"Growth at a Reasonable Price." The Fund invests in common stocks of high-quality &lt;br /&gt;companies that Barrett believes have superior growth potential and stocks that can &lt;br /&gt;be purchased at reasonable prices. The Fund makes investments in companies that &lt;br /&gt;have solid long-term earnings prospects and the Fund expects to hold these investments &lt;br /&gt;for prolonged periods of time, thereby avoiding short-term capital gains. The Adviser &lt;br /&gt;focuses on identifying companies that will produce earnings and cash flow growth in &lt;br /&gt;excess of companies in the Standard &amp;amp; Poor&apos;s 500 Composite Stock Price Index ("S&amp;amp;P &lt;br /&gt;500&amp;#xAE; Index"). The Adviser makes investments in companies that it believes produce &lt;br /&gt;superior earnings at reasonable valuations. Superior relative earnings growth is &lt;br /&gt;usually driven by new products and services; niche products in growth sectors and &lt;br /&gt;industries; open-ended global growth opportunities; and cyclical companies whose &lt;br /&gt;margins are benefiting from a recovery in their respective industries. Stocks are &lt;br /&gt;sold when there is likely to be deterioration in earnings growth or other financial&lt;br /&gt;metrics, including balance sheet items. Maintaining a competitive industry position &lt;br /&gt;and management stability are also important factors in retaining a company position. &lt;br /&gt;Unusually weak relative stock market performance is another signal that prompts the &lt;br /&gt;Adviser to immediately reevaluate a holding.&lt;br /&gt; &lt;br /&gt;The Adviser mitigates risk in several ways. In order to invest in a specific&lt;br /&gt;company the Adviser carefully analyzes the company&apos;s balance sheet and overall&lt;br /&gt;ability to withstand adverse economic conditions. More broadly, the Adviser&lt;br /&gt;diversifies the portfolio across multiple industries, economic sectors and&lt;br /&gt;geographic regions to reduce the risk of a particular industry&apos;s or region&apos;s&lt;br /&gt;weakness adversely affecting the total Fund. Since the Adviser focuses on buying&lt;br /&gt;companies at reasonable valuations, the risk of overpaying for companies with&lt;br /&gt;strong earnings growth is also reduced. The Fund invests in companies across the&lt;br /&gt;large - and mid-capitalization spectrum which provides the Fund with exposure to&lt;br /&gt;companies of different revenue and earnings levels. Finally, the Fund emphasizes&lt;br /&gt;objectivity in evaluating existing holdings and sells holdings when the&lt;br /&gt;fundamental outlook for a company is expected to deteriorate.&lt;br /&gt; &lt;br /&gt;From time to time, the Fund may purchase options, futures contracts or other&lt;br /&gt;instruments, such as depositary receipts, that relate to a particular stock&lt;br /&gt;index, to allow the Fund to quickly invest excess cash in order to gain &lt;br /&gt;exposure to the markets until the Fund can purchase individual stocks.&lt;/tt&gt;</rr:StrategyNarrativeTextBlock>

Remember, in addition to possibly not&lt;br /&gt;achieving your investment goals, you could lose money by investing in the&lt;br /&gt;Fund. The principal risks of investing in the Fund are:&lt;br /&gt; &lt;br /&gt;o Management Risk. The risk that investment strategies employed by the Adviser in&lt;br /&gt;&amp;#xA0;&amp;#xA0;selecting investments for the Fund may not result in an increase in the value&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;of your investment or in overall performance equal to other investments.&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;o General Market Risk. The risk that certain securities selected for the Fund&apos;s&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;portfolio may be worth less than the price originally paid for them, or less&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;than they were worth at an earlier time.&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;o Equity Market Risk. Common stocks are susceptible to general stock market&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;fluctuations and to volatile increases and decreases in value as market&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;confidence in and perceptions of their issuers change. Preferred stock is&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;subject to the risk that the dividend on the stock may be changed or omitted &lt;br /&gt;&amp;#xA0;&amp;#xA0;by the issuer and that participation in the growth of an issuer may be limited.&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;o Growth Stock Risk. The prices of growth stocks may be more sensitive to changes&lt;br /&gt;&amp;#xA0;&amp;#xA0;in current or expected earnings than the prices of other stocks.&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;o Foreign Securities Risk. The risk of investments in foreign companies,&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;including ADRs, which represent an ownership in a foreign security, involve&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;certain risks not generally associated with investments in the securities of&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;U.S. companies, including changes in currency exchange rates, unstable&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;political, social and economic conditions, a lack of adequate or accurate&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;company information, differences in the way securities markets operate, less&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;secure international banks or securities depositories than those in the U.S.&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;and foreign controls on investment. In addition, individual international&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;country economies may differ favorably or unfavorably from the U.S. economy in &lt;br /&gt;&amp;#xA0;&amp;#xA0;such respects as growth of gross domestic product, rates of inflation, capital &lt;br /&gt;&amp;#xA0;&amp;#xA0;reinvestment, resources, self-sufficiency and balance of payments position. &lt;br /&gt;&amp;#xA0;&amp;#xA0;These risks may also apply to U.S. companies that have substantial foreign &lt;br /&gt;&amp;#xA0;&amp;#xA0;operations.&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;o Large-Capitalization Company Risk. Larger, more established companies may be&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;unable to respond quickly to new competitive challenges such as changes in&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;consumer tastes or innovative smaller competitors. Also, large-capitalization&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;companies are sometimes unable to attain the high growth rates of successful,&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;smaller companies, especially during extended periods of economic expansion.&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;&lt;br /&gt;o Mid-Capitalization Company Risk. The mid-capitalization companies in which the &lt;br /&gt;&amp;#xA0;&amp;#xA0;Fund may invest may be more vulnerable to adverse business or economic events&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;than larger, more established companies. In particular, these mid-sized&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;companies may pose additional risks, including liquidity risk, because these&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;companies may have limited product lines, markets and financial resources, and &lt;br /&gt;&amp;#xA0;&amp;#xA0;may depend upon a relatively small management group. Therefore, mid-cap stocks &lt;br /&gt;&amp;#xA0;&amp;#xA0;may be more volatile than those of larger companies.&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt; &lt;br /&gt;o Options and Futures Risk. Options and futures may be more volatile than&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;investments in securities, involve additional costs and may involve a small&amp;#xA0;&amp;#xA0;&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;initial investment relative to the risk assumed. In addition, the value of an&amp;#xA0;&amp;#xA0;&lt;br /&gt;&amp;#xA0;&amp;#xA0;option or future may not correlate perfectly to the underlying securities index&lt;br /&gt;&amp;#xA0;&amp;#xA0;or overall securities markets.&lt;/tt&gt;</rr:RiskNarrativeTextBlock>
