  1If a Fund makes a distribution from any source other than net income, it is required to
          provide shareholders with a notice disclosing the source of such distribution (each a "Notice"). The
          amounts and sources of distributions reported above and in each Notice are only estimates and are not
          provided for tax reporting purposes. Each Fund will send each shareholder a Form 1099 DIV for the
          calendar year that will provide definitive information on how to report the Fund's distributions for
          federal income tax purposes. The information in the table above will not be updated to reflect any
          subsequent recharacterization of dividends and distributions. Click here to see recent
          Notices pertaining to the Fund (if any).
