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 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 December 31, 2011:
 
                         
   
Level 1
   
Level 2
   
Level 3

Municipal Bonds 
  $     $ 55,115,848     $     $ 55,115,848  
 
During the period ended December 31, 2011, the Fund recognized no significant transfers to or 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 December 31, 2011, the cost of investments was $51,542,905.
 
Gross unrealized appreciation and gross unrealized depreciation of investments at December 31, 2011, were as follows:
   
Gross unrealized: 
 
   Appreciation 
$2,782,251  
   Depreciation 
(210,764) 
Net unrealized appreciation (depreciation) of investments 
$2,571,487 
 
     
(1) 
 
All percentages shown in the Portfolio of Investments are based on net assets. 
(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. 
(3) 
 
Ratings: Using the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, 
   
Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. 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. 
N/R 
 
Not rated. 
(ETM) 
 
Escrowed to maturity. 
(IF) 
 
Inverse floating rate investment. 
(UB)
