Staff's comments and our responses are discussed below.

             and Qualifications of the Fund's Trustees: Information regarding
             skills, attributes and qualifications should be more specific in
             order to provide an explanation of the basis for the Board's

             and skills of Trustees are pursuant to requirements of the
             Commission, do not constitute holding out of the Board or any
             Trustee as having special expertise or experience and shall not be
             deemed to impose any greater responsibility or liability on any
             Trustee of on the Board by reason thereof", should be deleted.
