Two recent decisions of the US District Court for the Southern District of New York may complicate future debt exchange offers. The cases address the validity, under the Trust Indenture Act of 1939, as amended (the Act), of indenture amendments that delete substantive covenant protections in the context of out-of-court debt restructurings. Such amendments are a common feature of debt exchange and cash tender offers and are often essential to achieve a restructuring outside of bankruptcy court.
