*Distribution from "Other Sources" may contain sources of income other than ordinary income, such as short term capital gains, long term capital gains, or return of capital, which can not be determined until the close of the fund's fiscal year end. Distributions that are treated for federal income tax purposes as a return of capital will reduce a shareholder‘s tax basis in his or her shares and, to the extent the distribution exceeds a shareholder‘s adjusted tax basis, will be treated as a gain to the shareholder from a sale of shares. Please see the fund's most recent dividend source information available from payable date at for the breakdown of the distribution.
