Describe the types of securities issued by municipalities in the United States and distinguish between tax-backed debt and revenue bonds.
Some municipal bonds include a nonbinding pledge of additional tax revenue to make up any shortfalls; however legislative approval is required for the additional appropriation. These are known as moral obligation bonds. They are a form of general obligation debt, but most general obligation debt does not include such a pledge. In contrast, a prerefunded bond is backed by a trust of riskless securities that provide cash flows sufficient to pay the interest and principal payments of the bond.
