          90 days of the filing date of the report that includes the  disclosure

          240.15d-15(b)).

     (b)  There  were no  changes  in the  registrant's  internal  control  over
          financial  reporting (as defined in Rule  30a-3(d)  under the 1940 Act
          (17 CFR  270.30a-3(d))  that  occurred  during the  registrant's  last
          fiscal quarter that have materially affected, or are reasonably likely
