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 January 31, 2015, the cost of investments was $689,540,890.
 
Gross unrealized appreciation and gross unrealized depreciation of investments as of January 31, 2015, were as follows:
   
Gross unrealized:

All percentages shown in the Portfolio of Investments are based on net assets applicable to common
   
shares unless otherwise noted.

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

(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)
 
At or subsequent to the end of the reporting period, this security is non-income producing. Non-income
   
producing, in the case of a fixed-income security, generally denotes that the issuer has (1) defaulted on
   
the payment of principal or interest, (2) is under the protection of the Federal Bankruptcy Court or (3) the
   
Fund’s Adviser has concluded that the issue is not likely to meet its future interest payment obligations
   
and has directed the Fund’s custodian to cease accruing additional income on the Fund’s records.
(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)
 
Investment, or portion of investment, has been pledged to collateralize the net payment obligations for

filed for federal bankruptcy protection. On December 9, 2013, AMR emerged from federal bankruptcy with
   
the acceptance of its reorganization plan by the bankruptcy court. Under the settlement agreement
   
established to meet AMR’s unsecured bond obligations, the bondholders, including the Fund, received a
   
distribution of AAL preferred stock which was converted to AAL common stock over a 120-day period.
   
Every 30 days, a quarter of the preferred stock was converted to AAL common stock based on the 5-day
   
volume-weighted average price and the amount of preferred shares tendered during the optional preferred
   
conversion period.

During January 2010, Las Vegas Monorail Company (“Las Vegas Monorail”) filed for federal bankruptcy
   
protection. During March 2012, Las Vegas Monorail emerged from federal bankruptcy with the acceptance
   
of a reorganization plan assigned by the Federal Bankruptcy Court. Under the reorganization plan, the Fund

two senior interest corporate bonds: the first with an annual coupon rate of 5.500% maturing on July 15,
   
2019 and the second with an annual coupon rate of 3.000% (5.500% after December 31, 2015) maturing
