A portion of the Fund's current distribution may include sources other than net investment income, including a return of capital.

The notice should not be used to prepare tax returns as the estimates indicated in the notice may differ from the ultimate federal income tax characterization of distributions. After the end of each calendar year, investors will be sent a Form 1099-DIV informing them how to report distributions received during that year for federal income tax purposes.
