American Municipal Bond Assurance Corp
An insurer of municipal bonds and historically the first company to insure municipal bonds.
Now known as ĎAmbac Financial Group, Inc.í Bond insurers such as Ambac insure both the repayment of the principal and the interest payments of the bonds they insure. Insured bonds are therefore safer for bondholders, and this means issuers can offer them on terms that are less favorable in other ways than non-insured bonds. Itís common for municipal bonds to be insured.
