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 May 31, 2010:

Through its investments in the Underlying Portfolios, the Strategy currently has exposure to investments collateralized by subprime mortgage loans. Subprime loans are offered to homeowners who do not have a history of debt or who have had problems meeting their debt obligations. Because repayment is less certain, subprime borrowers pay a higher rate of interest than prime borrowers. As of May 31, 2010, the Strategy’s total exposure to subprime investments was 0.69% of net assets. These investments are valued in accordance with the Underlying Portfolio’s Valuation Policies.

(a) As of May 31, 2010, the cost basis of investment securities owned was substantially identical for both book and tax purposes. Gross unrealized appreciation of investments was $7,950,236 and gross unrealized depreciation of investments was $(23,606,829), resulting in net unrealized depreciation of $(15,656,593).

Through its investments in the Underlying Portfolios, the Strategy currently has exposure to investments collateralized by subprime mortgage loans. Subprime loans are offered to homeowners who do not have a history of debt or who have had problems meeting their debt obligations. Because repayment is less certain, subprime borrowers pay a higher rate of interest than prime borrowers. As of May 31, 2010, the Strategy’s total exposure to subprime investments was 0.05% of net assets. These investments are valued in accordance with the Underlying Portfolio’s Valuation Policies.

In accordance with U.S. GAAP regarding fair value measurements, fair value is defined as the price that the Strategy 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 Strategy. Unobservable inputs reflect the Strategy’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 Strategy’s own assumptions in determining the fair value of investments)

The following table summarizes the valuation of the Strategy’s investments by the above fair value hierarchy levels as of May 31, 2010:
