IQ employs the Sub-adviser, with respect to each Fund, to: (i) manage the investment and reinvestment of the assets of the Fund; (ii) continuously review, supervise and administer the investment program of the Fund (including the investment restrictions and guidelines of the Fund, the “Investment Program”); (iii) determine the securities to be purchased or sold and the portion of the Fund’s assets to be held uninvested in accordance with the Fund’s Investment Program; (iv) designate the identity and weighting of the Securities in the Deposit Securities and the Fund Securities (as such terms are defined in the Registration Statement) in accordance with the Fund’s Investment Program; (v) provide IQ and the Trust with records concerning the Sub-adviser’s activities which IQ is required to maintain as an investment adviser of a registered investment company pursuant to the 1940 Act (defined below) and Advisers Act (defined below) and the rules thereunder; (vi) file with the SEC all forms pursuant to Section 13F and 13G of the Securities Exchange Act of 1934; and (vii) render regular reports to IQ, the Trust’s officers and the Trust’s Board of Trustees (the “Board”) concerning the Sub-adviser’s discharge of the foregoing responsibilities.
