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. U.S. GAAP establishes 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 (including those valued based on their market values) 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 fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rates, coupon rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which is then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Other fixed income investments, including non-U.S. government and corporate debt, are generally valued using quoted market prices, if available, which are typically impacted by current interest rates, maturity dates and any perceived credit risk of the issuer. Additionally, in the absence of quoted market prices, these inputs are used by pricing vendors to derive a valuation based upon industry or proprietary models which incorporate issuer specific data with relevant yield/spread comparisons with more widely quoted bonds with similar key characteristics. Those investments for which there are observable inputs are classified as Level 2. Where the inputs are not observable, the investments are classified as Level 3.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of January 31, 2013:

Investments in Securities: Level 1 Level 2
Assets:
Long-Term Municipal Bonds $ – 0 – $ 679,941,013 $ 32,237,156 $ 712,178,169
Total Investments in Securities – 0 – 679,941,013 32,237,156 712,178,169
Other Financial Instruments* – 0 – – 0 – – 0 – – 0 –
Total^ $ – 0 – $ 679,941,013 $ 32,237,156 $ 712,178,169
  • Other financial instruments are derivative instruments, such as futures, forwards and swap contracts, which are valued at the unrealized appreciation/depreciation on the instrument.

^ There were no transfers between Level 1 and level 2 during the reporting period.

The Fund recognizes all transfers between levels of the fair value hierarchy assuming the financial instruments were transferred at the beginning of the reporting period.

The following is a reconciliation of investments in which significant unobservable inputs (Level 3) were used in determining fair value.

| Balance as of 10/31/12 | Long-Term
Municipal Bonds — $ 33,105,765 | | Total — $ 33,105,765 | |
| --- | --- | --- | --- | --- |
| Accrued discounts/(premiums) | (7,746 | ) | (7,746 | ) |
| Realized gain (loss) | (363,488 | ) | (363,488 | ) |
| Change in unrealized appreciation/depreciation | (620,666 | ) | (620,666 | ) |

The Adviser has established a Valuation Committee (the “Committee”) which is responsible for overseeing the pricing and valuation of all securities held in the Portfolio. The Committee operates under pricing and valuation policies and procedures established by the Adviser and approved by the Board, including pricing policies which set forth the mechanisms and processes to be employed on a daily basis to implement these policies and procedures. In particular, the pricing policies describe how to determine market quotations for securities and other instruments. The Committee’s responsibilities include: 1) fair value and liquidity determinations (and oversight of any third parties to whom any responsibility for fair value and liquidity determinations is delegated), and 2) regular monitoring of the Adviser’s pricing and valuation policies and procedures and modification or enhancement of these policies and procedures (or recommendation of the modification of these policies and procedures) as the Committee believes appropriate.

The Committee is also responsible for monitoring the implementation of the pricing policies by the Adviser’s Pricing Group (the “Pricing Group”) and a third party which performs certain pricing functions in accordance with the pricing policies. The Pricing Group is responsible for the oversight of the third party on a day-to-day basis. The Committee and the Pricing Group perform a series of activities to provide reasonable assurance of the accuracy of prices including: 1) periodic vendor due diligence meetings, review of methodologies, new developments and process at vendors, 2) daily compare of security valuation versus prior day for all securities that exceeded established thresholds, and 3) daily review of unpriced, stale, and variance reports with exceptions reviewed by senior management and the Committee.

In addition, several processes outside of the pricing process are used to monitor valuation issues including: 1) performance and performance attribution reports are monitored for anomalous impacts based upon benchmark performance, and 2) portfolio managers review all portfolios for performance and analytics (which are generated using the Adviser’s prices).
