On September 15, 2008, Lehman Brothers declared bankruptcy, an event considered by many to mark the beginning of the credit crisis of 2008–2009 and the unprecedented public policy responses that followed.

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.
