Double-Barreled Bond

A bond is said to be ?double-barreled? when it is secured by the pledge of two (or more) sources of payment. In some states a bond secured in the first instance by a user charge, e.g., water or sewer, may be additionally secured by ad valorem taxes if the user charges don't bring enough revenue.

Remarks: Bond funds including mutual funds (open-end and closed-end, actively managed and indexed), exchange-traded funds and unit investment trusts offer a convenient and affordable way to invest in a diversified portfolio of bonds, but a bond fund investment can differ from a bond investment in ways that are important to understand.
