In the aftermath of recent municipal bankruptcies in which issuers proposed and/or implemented bankruptcy plans involving partial discharges of the issuer’s payment obligation on insured bonds, there has been increased focus on whether municipal bond interest paid by a bond insurer after the bankruptcy plan’s effective date continues to be tax-exempt.

On August 9, 2011, the United States Court of Appeals for the Fifth Circuit held that a non-insider's debt claim can be recharacterized as equity in Grossman v. Lothian Oil Inc. (In re Lothian Oil, Inc.).2 The Fifth Circuit, in reversing the district court, held that: (i) there is no per se rule limiting to insiders the recharacterization of debt claims as equity and (ii) non-insider debt claims may be recharacterized as equity under section 502(b) of the Bankruptcy Code.
