Certified copy of the resolutions dated October 20, 2017 of the Trust's Board of Trustees, including a majority of the Trustees who are not "interested persons" (as defined by the 1940 Act) of the Trust, approving the amount, type, form and coverage of the Bond, and the portion of the premium to be paid by the Trust; and
