The following constitutes Amendment No. 15 to the Schedule 13D filed by the undersigned ("Amendment No. 15"). This Amendment No. 15 amends the Schedule 13D as specifically set forth herein.

Item 2.

Identity and Background.

Item 2(a) is hereby amended and restated to read as follows:

(a) This statement is filed by:

(i) Karpus Management, Inc., d/b/a Karpus Investment Management ("Karpus"). Karpus is a registered investment adviser under Section 203 of the Investment Advisers Act of 1940. Karpus is controlled by City of London Investment Group plc (“CLIG”), which is listed on the London Stock Exchange. However, in accordance with SEC Release No. 34-39538 (January 12, 1998), effective informational barriers have been established between Karpus and CLIG such that voting and investment power over the subject securities is exercised by Karpus independently of CLIG, and, accordingly, attribution of beneficial ownership is not required between Karpus and CLIG. The shares to which this Amendment No. 15 relates are owned directly by the accounts managed by Karpus;

Set forth on Schedule A annexed hereto ("Schedule A") is the name and present principal business, occupation or employment and the name, principal business and address of any corporation or other organization in which such employment is conducted of the executive officers and directors of Karpus. To the best of the Reporting Persons' knowledge, except as otherwise set on Schedule A, none of the persons listed on Schedule A beneficially owns any securities of the Issuer or is a party to any contract, agreement or understanding required to be disclosed herein.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 is hereby amended and restated to read as follows:

Karpus, an independent registered investment advisor, has accumulated 0 Shares on behalf of accounts that are managed by Karpus (the “Accounts”) under limited powers of attorney.

		3. Sole power to dispose or direct the disposition: 0
		4. Shared power to dispose or direct the disposition: 0

(c)

Each of the Reporting Persons specifically disclaims beneficial ownership of the securities reported herein that he or it does not directly own.

As a result of the Issuer's merger into DNP Select Income Fund Inc.
