Make-whole clauses (also known as prepayment premiums, call premiums or call protection) are provisions in financing transactions that require the borrower to make a specified payment to the lender if a loan is prepaid before the scheduled maturity. This payment is typically made by the borrower as a lump sum upon early termination and is designed to compensate the lender for the loss of the anticipated yield that lenders expect when providing (or committing to provide) the financing over a specified term.

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.
