You should not draw any conclusions about the Trust’s investment performance from the amount of this distribution or from the terms of the Trusts Managed Distribution Plan.

The Trust estimates that it has distributed more than its income and net realized 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 Trust is paid back to you. A return of capital does not necessarily reflect the Trust’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 in the 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 Trust’s investment experience during the remainder of its fiscal year and may be subject to changes based on the tax regulations. The Trust will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purpose.
