Fair Value Measurements
Fair value is defined as the price that the Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels. Level 1 - Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities. Level 2 - Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.). Level 3 - Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments). The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of the Fund’s fair value measurements as of the end of the reporting period:
		Level 1	Level 2	Level 3	Total
Long-Term Investments:
$25 Par (or similar) Retail Preferred		$  283,520,749	$    26,056,017	$            —	$  309,576,766

Income Tax Information
The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to recognition of premium amortization, timing differences in the recognition of income and timing differences in recognizing certain gains and losses on investment transactions. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts on the Statement of Assets and Liabilities presented in the annual report, based on their federal tax basis treatment; temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset value of the Fund. As of April 30, 2014, the cost of investments (excluding investments in derivatives) was $769,079,197. Gross unrealized appreciation and gross unrealized depreciation of investments (excluding investments in derivatives) as of April 30, 2014, were as follows:
Gross unrealized:
Appreciation					$  60,634,598
Depreciation					(9,131,623	)
Net unrealized appreciation (depreciation) of investments					$  51,502,975
