Fund
Distributions and Managed Distribution Plan: DNP Select Income Fund Inc. (“DNP” or the “Fund”) has been paying a regular 6.5 cent per share monthly distribution on its common stock since July 1997. In February 2007, the Board of Directors adopted a Managed Distribution Plan, which provides for the Fund to continue to make a monthly distribution on its common stock of 6.5 cents per share. Under the Managed Distribution Plan, the Fund will distribute all available investment income to shareholders, consistent with the Fund’s primary investment objective. If and when sufficient investment income is not available on a monthly basis, the Fund will distribute long-term capital gains and/or return capital to its shareholders in order to maintain the steady distribution level that has been approved by the Board. If the Fund estimates that it has distributed more than its income and capital gains in a particular period, 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
