The Comptroller of the Currency (OCC) has recently concluded that the resecuritization of certain residential mortgage-backed securities by a bank is permitted through its subsidiary.

In its Interpretive Letter # 1133 (September 2011), the OCC determined that a bank could consummate a certain type of structured transaction in order to enhance the marketability of the underlying interests and its liquidity position and to address regulatory concerns relating to its exposure to non-investment grade securities.

The OCC's consent was based, among other things, on the petitioning bank's representations that it would adhere to prudential requirements and supervisory guidance on safe and sound banking practices and that it would establish and maintain, to the OCC's satisfaction, "an adequate and effective risk measurement and management program."
