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, In re Castleton Plaza, LP, 2013 WL 537269 *1 (Feb. 14, 2013), the Seventh Circuit held that the absolute priority rule – which requires that creditors be paid in full before equity holders receive anything on account of their equity interests under a plan of reorganization – applies equally to the “insiders” of a debtor.
