Standard&Poor's Ratings Services affirmed its ratings on Merrill Lynch Puttable FLOATs/RITES Trust puttable residual interest tax-exempt receipts due to a review of the amendment memorandum and amendment to the series trust agreement and other relevant documents, from which we conclude that the amendment will not result in a reduction or withdrawal of the current ratings Standard&Poor's has assigned to the captioned P-FLOATs.
