The Board is publishing revisions to the official staff commentary to Regulation M, which implements the Consumer Leasing Act. The act requires lessors to provide uniform cost and other disclosures about consumer lease transactions. Regulation M was revised in September 1996 under the Board's Regulatory Planning and Review program, which calls for the periodic review of Board regulations. The commentary applies and interprets the requirements of Regulation M. The revisions to the commentary provide guidance on the final rule issued in September 1996, as amended in April 1997.
