NOTES TO STATEMENT OF NET ASSETS

(UNAUDITED)

JANUARY 31, 2012

Note 1. Security Valuation

The Fund’s investments are carried at fair value which is defined as the price that the Fund would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market of the investment. The three-tier hierarchy of inputs established to classify fair value measurements for disclosure purposes is summarized in the three broad levels listed below.

Level 1—quoted prices in active markets for identical securities

Level 2—other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment spreads, credit risks, etc.)

Level 3—significant unobservable inputs (including the Fund’s own assumptions in determining fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in these securities. For more information about the Fund’s policy regarding valuation of investments and other significant accounting policies, please refer to the Fund’s most recent financial statements contained in its annual report. The following is a summary of the inputs used to value each of the Fund’s investments at January 31, 2012:

	Level 1
Common Stocks & MLP Interests	$	956,214,508
Total	$	956,214,508

There were no Level 2 or Level 3 priced securities held at January 31, 2012. There were no transfers between Level 1 and Level 2 during the quarter ended January 31, 2012.

Note 2. Federal Income Tax Information

At January 31, 2012, the federal tax cost of the Fund’s investments and aggregate gross unrealized appreciation (depreciation) were as follows:

Federal Tax Cost	Unrealized Appreciation	Unrealized Depreciation	Net Unrealized Appreciation
$928,756,123	$57,139,350	$(29,680,965)	$27,458,385
