$0.35 ARIVA.DE Börsen-Geflüster Kurse Duff & Phelps Global Utility I 9,09 $ 0,00% Virtus Investment Partners 206,00 € -0,96%	September 13, 2016	September 15, 2016	September 30, 2016

The Fund adopted a Managed Distribution Plan (the "Plan") in 2015 to maintain its current 35 cent per share distribution rate.  Under the Plan, the Fund will distribute all available investment income to its shareholders, consistent with the Fund's investment objective.  If and when sufficient investment income is not available on a quarterly basis, the Fund will distribute realized capital gains and/or return of capital to its shareholders in order to maintain the 35 cent per share distribution level.

The following table sets forth the estimated amounts of the Fund's June quarterly distribution to shareholders of record at the close of business on June 15, 2016 (ex-date June 13, 2016), payable June 30, 2016, together with the cumulative distributions paid this fiscal year to date from the following sources.  All amounts are expressed per share of common stock based on U.S. generally accepted accounting principles which may differ from federal income tax regulations.

You should not draw any conclusions about the Fund's investment performance from the amount of these distributions or from the terms of the Fund's 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 the 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.

The Fund will issue a separate 19(a) notice at the time of each quarterly distribution using the most current financial information available.
