A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall.

Technology, telecommunications and health care companies may also be affected by legislation or changes in government regulation and policies.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.</p><p>Midsize Companies</p><p>Securities issued by midsize companies may be more volatile in price than those of larger companies, involve substantial risks and should be considered speculative. Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. Investment management applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p><p>Growth Style Investing</p><p>Growth stock prices reflect projections of future earnings or revenues, and can, therefore, fall dramatically if the company fails to meet those projections.

If there were expense reimbursement or fee waiver arrangements that reduced any Fund operating expenses and will continue to reduce them for no less than one year from the effective date of the Fund's registration statement, a Fund may add two captions to the table one caption showing the amount of the expense reimbursement or fee waiver, and a second caption showing the Fund's net expenses after subtracting the fee reimbursement or expense waiver from the total fund operating expenses. The Fund should place these additional captions directly below the "Total Annual Fund Operating Expenses" caption of the table and should use appropriate descriptive captions, such as "Fee Waiver [and/or Expense Reimbursement]" and "Total Annual Fund Operating Expenses After Fee Waiver [and/or Expense Reimbursement]," respectively.

Such advantages as a particular marketing niche, proven technology, sound financial records, strong management, and industry leadership are all factors the investment manager believes point to strong growth potential.

A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term.

Such risks may include greater sensitivity to economic conditions, less certain growth prospects, lack of depth of management and funds for growth and development and limited or less developed product lines and markets. In addition, smaller companies may be particularly affected by interest rate increases, as they may find it more difficult to borrow money to continue or expand operations, or may have difficulty in repaying any loans.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.</p><p>Focus</p><p>To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio.

The Fund may shift its investments from one asset class to another based on the investment managers' analysis of the best opportunities for the Fund&#146;s portfolio in a given market. The equity securities in which the Fund invests consist primarily of common stocks. Debt securities include all varieties of fixed, floating and variable rate instruments, including secured and unsecured bonds, bonds convertible into common stock, mortgage and asset-backed securities, debentures, and shorter term instruments. The Fund seeks income by selecting investments such as corporate, foreign and U.S. Treasury bonds, as well as stocks with dividend yields the manager believes are attractive. The Fund may invest up to 100% of its total assets in debt securities that are rated below investment grade (also known as "junk bonds"), including a portion in defaulted securities. The Fund maintains the flexibility to invest in securities of companies from a variety of sectors, but from time to time, based on economic conditions, the Fund may have significant investments in particular sectors. The Fund may also invest up to 25% of its assets in foreign securities, either directly or through depositary receipts.</p><p>The Fund's investment manager searches for undervalued or out-of-favor securities it believes offer opportunities for income today and significant growth tomorrow. It generally performs independent analysis of the debt securities being considered for the Fund's portfolio, rather than relying principally on the ratings assigned by rating organizations. In analyzing both debt and equity securities, the manager considers a variety of factors, including:</p><p>a security's relative value based on such factors as anticipated cash flow, interest or dividend coverage, asset coverage, and earnings prospects;</p><p>the experience and strength of the company's management;</p><p>the company's changing financial condition and market recognition of the change;</p><p>the company's sensitivity to changes in interest rates and business conditions; and</p><p>the company's debt maturity schedules and borrowing requirements.</p><p>When choosing equity investments for the Fund, the investment manager applies a "bottom-up," long-term approach, focusing on the market price of a company's securities relative to the investment manager's evaluation of the company's long-term earnings, asset value and cash flow potential. The investment manager also considers a company's price/earnings ratio, profit margins and liquidation value.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value.</p><p>High-Yield Debt Securities</p><p>Issuers of lower-rated or "high yield" debt securities are not as strong financially as those issuing higher credit quality debt securities. These issuers are more likely to encounter financial difficulties and are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high yield debt securities generally fluctuate more than those of higher credit quality. High yield debt securities are generally more illiquid (harder to sell) and harder to value.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Interest Rate</p><p>When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these price changes.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.</p><p>Foreign Securities</p><p>Investing in foreign securities typically involves more risks than investing in U.S. securities, including risks related to currency exchange rates and policies, country or government specific issues, less favorable trading practices or regulation and greater price volatility. Certain of these risks also may apply to securities of U.S. companies with significant foreign operations.</p><p>Focus</p><p>To the extent that the Fund focuses on particular countries, regions, industries, sectors or types of investment from time to time, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of countries, regions, industries, sectors or investments.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. Investment management applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p><p>Prepayment</p><p>Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest.</p><p>Value Style Investing</p><p>A value stock may not increase in price as anticipated by the investment manager if other investors fail to recognize the company's value and bid up the price, the markets favor faster-growing companies, or the factors that the investment manager believes will increase the price of the security do not occur.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Ginnie Maes</p><p>Ginnie Maes differ from conventional corporate debt securities because principal is paid back monthly over the life of the security rather than at maturity. The Fund may receive unscheduled prepayments of principal due to voluntary prepayments, refinancing or foreclosure on the underlying mortgage loans. Because of repayments, Ginnie Maes may be less effective than some other types of securities as a means of "locking in" long-term interest rates and may have less potential for capital appreciation during periods of falling interest rates. A reduction in the anticipated rate of principal prepayments, especially during periods of rising interest rates, may increase the effective maturity of Ginnie Maes, making them more susceptible than some other debt securities to a decline in market value when interest rates rise.</p><p>Interest Rate</p><p>When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. In general, securities with longer maturities are more sensitive to these price changes.</p><p>Credit</p><p>An issuer of debt securities may fail to make interest payments and repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's credit rating may affect a security's value. While securities issued by Ginnie Mae are backed by the full faith and credit of the U.S. government, not all securities of the various U.S. government agencies are, including those of Fannie Mae and Freddie Mac. Also guarantees of principal and interest do not apply to market prices, yields or the Fund&#146;s share price. While the U.S. government has recently provided financial support to Fannie Mae and Freddie Mac, no assurance can be given that the U.S. government will always do so, since the U.S. government is not so obligated by law.</p><p>Income</p><p>Because the Fund can only distribute what it earns, the Fund's distributions to shareholders may decline when prevailing interest rates fall or when the Fund experiences defaults on debt securities it holds.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. Investment management applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Prepayment</p><p>Prepayment risk occurs when a debt security can be repaid in whole or in part prior to the security's maturity and the Fund must reinvest the proceeds it receives, during periods of declining interest rates, in securities that pay a lower rate of interest.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.

Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.</p><p>Utilities Industry</p><p>Utility company equity securities, which are generally purchased for their dividend yield, historically have been sensitive to interest rate movements: when interest rates have risen, the stock prices of these companies have tended to fall. In some states, utility companies and their rates are regulated; other states have moved to deregulate such companies thereby causing non-regulated companies&#146; returns to generally be more volatile and more sensitive to changes in revenue and earnings. In general, all utility companies may face additional regulation and litigation regarding emissions from their power plants; increased costs from new or greater regulation of greenhouse gas emissions; and the need to purchase expensive emissions control equipment due to regulations, all of which may lower their earnings.</p><p>Market</p><p>The market value of securities owned by the Fund will go up and down, sometimes rapidly or unpredictably. A security&#146;s market value may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all securities. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.</p><p>Generally, stocks have historically outperformed other types of investments over the long term. Individual stock prices, however, tend to go up and down more dramatically. A slower-growth or recessionary economic environment could have an adverse effect on the price of the various stocks held by the Fund.</p><p>Concentration</p><p>By focusing on an industry or a group of industries, the Fund carries much greater risks of adverse developments and price movements in such industries than a fund that invests in a wider variety of industries. Because the Fund concentrates in a specific industry or group of industries, there is also the risk that the Fund will perform poorly during a slump in demand for securities in such industries.</p><p>Management</p><p>The Fund is subject to management risk because it is an actively managed investment portfolio. Investment management applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.</p></div>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
