Fair Value Measurements
 
Fair value is defined as the price that would be received 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:

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 timing differences in recognizing taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate securities reflected as financing transactions, if any. 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 May 31, 2017, the cost of investments was $467,669,755.
 
Gross unrealized appreciation and gross unrealized depreciation of investments as of May 31, 2017, were as follows:
   
Gross unrealized: 
 
Appreciation 
$30,757,458 
Depreciation 
(1,659,145) 
Net unrealized appreciation (depreciation) of investments 
$29,098,313 
 
(1) 
  
All percentages shown in the Portfolio of Investments are based on net assets applicable to common 
 
  
shares unless otherwise noted. 
(2) 
  
Optional Call Provisions: Dates (month and year) and prices of the earliest optional call redemption. 
 
  
There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities 
 
  
may be subject to periodic principal paydowns. 
(3) 
  
For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor's Group 
 
  
("Standard & Poor's"), Moody's Investors Service, Inc. ("Moody's") or Fitch, Inc. ("Fitch") rating. This 
 
  
treatment of split-rated securities may differ from that used for other purposes, such as for Fund 
 
  
investment policies. Ratings below BBB by Standard & Poor's, Baa by Moody's or BBB by Fitch are 
 
  
considered to be below investment grade. Holdings designated N/R are not rated by any of these 
 
  
national rating agencies. 
(4) 
  
Investment, or portion of investment, has been pledged to collateralize the net payment obligations for 
 
  
investments in inverse floating rate transactions. 
(5) 
  
Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, 
 
  
which ensure the timely payment of principal and interest. Certain bonds backed by U.S. Government or 
 
  
agency securities are regarded as having an implied rating equal to the rating of such securities. 
(6) 
  
Variable Rate MuniFund Term Preferred Shares, net of deferred offering costs as a percentage of 
 
  
Total Investments is 34.0%. 
(ETM) 
  
Escrowed to maturity. 
(IF) 
  
Inverse floating rate investment. 
(UB) 
  
Underlying bond of an inverse floating rate trust reflected as a financing transaction. 
(WI/DD) 
  
Investment, or portion of investment, purchased on a when-issued or delayed delivery basis.
