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 of 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 three-tier hierarchy of inputs 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 risk, etc.).
 
 
Level 3 – 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 risk associated with investing in those securities. The following is a summary of the Fund's fair value measurements as of May 31, 2011:
 
         
 
Level 1 
Level 2 
Level 3 
Total 
Investments: 
        
Municipal Bonds 
$ — 
$115,523,568 
$ — 
$115,523,568 
 
 
During the period ended May 31, 2011, the Fund recognized no significant transfers to/from Level 1, Level 2 or Level 3.
 
 
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.
 
 
At May 31, 2011, the cost of investments was $116,218,435.
 
 
Gross unrealized appreciation and gross unrealized depreciation of investments at May 31, 2011, were as follows:
 
   
Gross unrealized: 
  
Appreciation 
$ 2,509,196 
Depreciation 
(6,561,731)
Net unrealized appreciation (depreciation) of investments 
$(4,052,535)
 
     
   
The Fund intends to invest at least 80% of its managed assets in municipal securities that are covered by 
   
insurance guaranteeing the timely payment of principal and interest. 
(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 or redemption. 
   
There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities 
   
may be subject to periodic principal paydowns.

any of these national rating agencies. 
(4)
