Certain footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from this report pursuant to the rules of the SEC.

Fair Value Measurements

The Fund's investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Board of Directors/Trustees. 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. U.S. GAAP establishes the three-tier hierarchy which 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 management’s 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, credit spreads, etc.).

Level 3  –     Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

The following table summarizes the market value of the Fund's investments as of the end of the reporting period, based on the inputs used to value them:
