1The Fund estimates that it has distributed more than its income and net-realized capital gains in the current fiscal year; therefore, a portion of your distribution may be a return of capital. A return of capital may occur, for example, when some or all of the shareholder’s investment is paid back to the shareholder. A return of capital distribution does not necessarily reflect the Fund's investment performance and should not be confused with ‘yield’ or ‘income’. When distributions exceed total return performance, the difference will reduce the Fund’s net asset value per share.

The amounts and sources of distributions reported are only estimates and are being provided to you pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon each Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.
