July 31, 2012 (unaudited)

In accordance with U.S. GAAP regarding fair value measurements, fair value is defined as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The U.S. GAAP disclosure requirements establish a framework for measuring fair value, and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Fund. Unobservable inputs reflect the Fund’s own assumptions about the assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances. Each investment is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-tier hierarchy of inputs is summarized below.

• Level 1—quoted prices in active markets for identical investments

• Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

• Level 3—significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of July 31, 2012:

Investments in Securities: Level 1 Level 2
Assets:
Long-Term Municipal Bonds $ – 0 – $ 697,346,307 $ 28,246,421 $ 725,592,728
Total Investments in Securities – 0 – 697,346,307 28,246,421 725,592,728
Other Financial Instruments* – 0 – – 0 – – 0 – – 0 –
Total $ – 0 – $ 697,346,307 $ 28,246,421 $ 725,592,728
  • Other financial instruments are derivative instruments, such as futures, forwards and swap contracts, which are valued at the unrealized appreciation/depreciation on the instrument.

Following is a reconciliation of investments in which significant unobservable inputs (Level 3) were used in determining fair value. The transfers between levels of the fair value hierarchy assumes the financial instrument was transferred at the beginning of the reporting period.

| Balance as of 10/31/11 | Long-Term
Municipal Bonds — $ 30,276,122 | $ | (4,384,798 | ) | Total — $ 25,891,324 | |

| Realized gain (loss) | (362,922 | ) | (818,289 | ) | (1,181,211 | ) |

^ There were di minimis transfers under 1% of net assets during the reporting period.

The following presents information about significant unobservable inputs related to the Fund’s material categories of Level 3 investments at July 31, 2012:

Fair Value at 7/31/2012 Valuation Technique Unobservable Input Range
Long-Term Municipal Bonds $ 28,246,421 Broker Quotes Yield 0.39-19.052 %

Corporate, Government, Agency, and Municipal Securities

The significant unobservable inputs used in the fair value measurement of the Fund’s Corporate, Government, Agency, and Municipal Securities are non-agency quality ratings, spreads on non-rated instrument, and yields on non-rated instruments. On non-evaluated assets, broker quotes are used when other market information not available to produce an evaluation and are considered non-observable. Generally, an increase in spreads or a decrease in yields leads to an inverse move in the price of the assets. A decrease in rating or absence of a rating is accompanied by a directionally opposite change in price.

The significant unobservable inputs used in the fair value measurement of the Fund’s Private Corporate and Asset Backed Securities are the spread over the public curve as well as the spreads or yields on non-rated instruments.
