Distributions may include ordinary income, net capital gains and/or returns of capital. Generally, a return of capital would occur when the amount distributed by the Fund includes a portion of (or is comprised entirely of) your investment in the Fund in addition to (or rather than) your pro-rata portion of the Fund's net income or capital gains. The Fund's distributions in any period may be more or less than the net return earned by the Fund on its investments, and therefore should not be used as a measure of performance or confused with "yield" or "income." A return of capital is not taxable; rather it reduces a shareholder's tax basis in his or her shares of the Fund. If the Fund estimates that a portion of its distribution may be comprised of amounts from sources other than net investment income, the Fund will notify shareholders of the estimated composition of such distribution through a separate written Section 19 notice. Such notices are provided for informational purposes only, and should not be used for tax reporting purposes. Final tax characteristics of all Fund distributions will be provided on Form 1099-DIV, which is mailed after the close of the calendar year.

As with any stock, the price of the Fund's common shares will fluctuate with market conditions and other factors. Shares of closed-end management investment companies frequently trade at a price that is less than (a "discount") or more than (a "premium") their net asset value. If the Fund's shares trade at a premium to net asset value, there is no assurance that any such premium will be sustained for any period of time and will not decrease, or that the shares will not trade at a discount to net asset value thereafter.

Investments, including investments in closed-end funds, carry risks and investors may lose principal value. Capital markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, or economic developments. It is important to remember that there are risks inherent in any investment and there is no assurance that any investment or asset class will provide positive performance over time. Value style investing presents the risk that the holdings or securities may never reach our estimate of intrinsic value because the market fails to recognize what the portfolio management team considers the true business value or because the portfolio management team has misjudged those values. In addition, value style investing may fall out of favor and underperform growth or other style investing during given periods. Non-U.S. investing presents additional risks, such as the potential for adverse political, currency, economic, social or regulatory developments in a country, including lack of liquidity, excessive taxation, and differing legal and accounting standards. Non-U.S. securities, including American Depository Receipts (ADRs) and other depository receipts, are also subject to interest rate and currency exchange rate risks.

Fixed income securities are subject to interest rate, inflation and credit risks. Lower rated bonds, convertible securities, and other types of debt obligations involve greater risks than higher rated bonds. Mortgage securities and collateralized mortgage obligations (CMOs) are subject to prepayment risk and the risk of default on the underlying mortgages or other assets; such derivatives may increase volatility. Convertible securities are generally not investment grade and are subject to greater credit risk than higher-rated investments. High yield securities can be volatile and subject to much higher instances of default.
