The Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, the Farm Credit Administration, and the Federal Housing Finance Agency (collectively the "Agencies"), reopened the comment period on the proposed rule published in the Federal Register on May 11, 2011 (76 FR 27564) to establish minimum margin and capital requirements for uncleared swaps and security-based swaps entered into by swap dealers, major swap participants, security based swap dealers, and major security-based swap participants, for which one of the Agencies is the prudential regulator (Proposed Margin Rule). Reopening the comment period allowed interested persons additional time to analyze and comment on the Proposed Margin Rule in light of the consultative document on margin requirements for non-centrally-cleared derivatives recently published for comment by the Basel Committee on Banking Supervision and the International Organization of Securities Commissions.  This RIN has been withdrawn and replaced with RIN 3064-AE21.
