You should not draw any conclusions about the fund’s investment performance from the amount of this distribution or from the terms of the fund’s managed distribution plan.

The fund estimates that it has distributed more than its income and capital gains; 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 money that you invested in the fund is paid back to you. A return of capital distribution does not necessarily reflect the fund’s investment performance and should not be confused with “yield” or “income.”

The amounts and sources of distributions reported in this notice are only estimates and are not being provided for tax-reporting purposes. The actual amounts and sources of the amounts for tax-reporting purposes will depend upon the 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.

If you have any questions regarding this information, please call our fund service department at 1-800-637-2304 any business day from 9 a.m. to 5 p.m. Eastern time.
