Note 1. Investment Valuation

The Fund’s investments are carried at fair value which is defined as the price that the Fund might reasonably expect to 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 speeds, 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 July 31, 2023:

	Level 1
Common stocks & MLP interests	$598,391,246
Total investments	$598,391,246

There were no Level 2 or Level 3 priced securities held and there were no transfers into or out of Level 3.
