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.

In a recent decision by the influential Third Circuit Court of Appeals, In re KB Toys Inc., 2013 U.S. App. LEXIS 23083 at *17 (3d Cir. Nov. 15, 2013), the Court decided that “the cloud on the claim” stemming from a preferential payment made to the original claimant continues with the claim, which then could be disallowed.
