The two main
forms of municipal bonds are general obligation and revenue.
These two types are distinguished according
to whether they are secured or unsecured (these distinctions will be briefly
discussed later).
General
obligation bonds (GO bonds) are unsecured municipal bonds that finance
municipal operations.
GO bonds have
maturities of 10 years or more. The creditworthiness of the issuing city or
state is the only "security" they provide. GO bonds finance projects that do not
produce revenue.
The municipal issuer repays the bonds with funds raised by fees
or property sales. If it is unable to, it may turn to taxation to guarantee
interest and principal payments.
Generally, all the individual bonds in a GO bond issue have the
same maturity date.
