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.

The actual amounts and sources of the amounts for accounting and/or 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.
