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 or liability (including those valued based on their market values). 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)

Where readily available market prices or relevant bid prices are not available for certain equity investments, such investments may be valued based on similar publicly traded investments, movements in relevant indices since last available prices or based upon underlying company fundamentals and comparable company data (such as multiples to earnings or other multiples to equity). Where an investment is valued using an observable input, by pricing vendors, such as another publicly traded security, the investment will be classified as Level 2. If management determines that an adjustment is appropriate based on restrictions on resale, illiquidity or uncertainty, and such adjustment is a significant component of the valuation, the investment will be classified as Level 3. An investment will also be classified as Level 3 where management uses company fundamentals and other significant inputs to determine the valuation.

The following table summarizes the valuation of the Fund’s investments by the above fair value hierarchy levels as of April 30, 2016:

(a) See Portfolio of Investments for sector classifications.

(b) Other financial instruments are derivative instruments, such as futures, forwards and swaps, which are valued at the unrealized appreciation/depreciation on the instrument.

(c) There were no transfers between any levels 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 Adviser established the Valuation Committee (the “Committee”) to oversee the pricing and valuation of all securities held in the Fund. 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) Fund managers review all portfolios for performance and analytics (which are generated using the Adviser’s prices).
