Fund Description: iShares S&P GSCI Commodity-Indexed Trust is a Delaware statutory trust that will issue units of beneficial interest, called Shares, representing fractional undivided beneficial interests in its net assets. Substantially all of the assets of the Trust consist of its holdings of the limited liability company interests of a commodity pool, which are the only securities in which the Trust may invest. That commodity pool, iShares GSCI Commodity-Indexed Investing Pool LLC, or the Investing Pool, will hold long positions in futures contracts on the GSCI Excess Return Index, called CERFs, listed on the Chicago Mercantile Exchange and will post margin in the form of cash or short-term securities to collateralize its CERF positions. It is the objective of the Trust that the performance of the Shares will correspond generally to the performance of the GSCI Total Return Index before payment of the Trust’s and the Investing Pool’s expenses and liabilities. The Index is intended to reflect the performance of a diversified group of commodities. The commodities represented in the GSCI-ER are those physical commodities on which active and liquid contracts are traded on trading facilities in major industrialized countries. TRUST MANAGEMENT: BlackRock Fund Advisers serves as the commodity trading adviser of the Investment Pool.
