Which of the following statements is true of a tax-free municipal revenue bond?

A municipal revenue bond is secured by and payable from a specific source of revenue, such as tolls from a bridge, fares from a transit system, fees from a water/sewer utility, or revenues from an airport authority. Bondholders rely on that pledged revenue stream rather than the issuer’s general taxing power. That is why the correct statement is C: bondholders are entitled to be paid only from a specified source of revenue.

Choice A is incorrect because revenue bond proceeds are typically earmarked for the project or enterprise, and repayment is not treated as “general revenue” in the GO sense. Choice B is incorrect because bondholders do not have a claim on any revenue of the issuer; that description aligns more with general obligation backing or a broad pledge. Choice D is incorrect because bondholders are owed debt service per the bond’s terms (interest and principal), not a “specified percentage” of issuer revenue.

The phrase “tax-free” refers to the typical federal tax-exempt status of municipal bond interest (subject to exceptions), but it does not change the fundamental revenue bond structure: repayment depends on the project’s performance and revenue collection. This is a key SIE distinction between GO bonds (supported by full faith and credit/taxing power) and revenue bonds (supported by a designated revenue stream).
