What is a Utility Revenue Bond?
Let me explain what a utility revenue bond is. It's also known as an essential service bond, and it's a type of municipal bond that you might encounter when financing a public utility. The key point here is that it repays bondholders directly from the revenues generated by the project itself, not from some general tax fund.
Key Takeaways
You should know that a utility revenue bond is essentially a municipal bond designed to finance a public utility project, with repayments coming straight from the project's revenues to investors. Because these bonds support necessary services, they often come with a net revenue pledge. As an investor, you'll want to look at metrics like the coverage ratio to assess these bonds and the underlying projects.
Understanding Utility Revenue Bonds
When I talk about utility revenue bonds, I'm referring to bonds used to fund capital projects in essential public service areas. Think hospitals, fire services, water and waste treatment facilities, or upgrades to the electrical grid. These services make money through fees from customers, and that cash flow is what services the debt.
Revenue bonds can have either a gross revenue pledge or a net revenue pledge. With a gross revenue pledge, bondholder payments take priority over any operational or maintenance costs for the project. On the other hand, a net revenue pledge lets the project pay for administrative expenses and upkeep first, before addressing obligations to bondholders.
Utilities provide vital services like water and electricity, and because they're so necessary, utility revenue bonds typically feature a net revenue pledge. This ensures that upkeep is done to keep everything in good working order.
It's also standard for utilities to maintain a specific revenue-to-expenditure ratio, where debt repayment counts as an expense. This ratio often justifies rate increases for customers in public utilities.
Paying Back Utility Revenue Bonds
Municipal bonds repay bondholders in different ways. General obligation bonds use municipal taxation, but revenue bonds like these draw income directly from the capital project. With general obligation bonds, the issuer guarantees repayment by any means necessary—they can raise taxes, issue more bonds, or even sell assets. They're not limited to one revenue stream. As an investor, you need to understand this difference when building a diversified fixed-income portfolio.
Other factors matter when credit ratings agencies or investors evaluate utility revenue bonds and their projects. The coverage ratio helps determine if expected revenues can cover principal and interest obligations. Population size and trends give insights into potential future revenue growth or decline for a utility project.
Customer concentration looks at the mix of consumers whose fees support the debt repayment. If just a few consumers account for a large portion of the utility's service usage, that could introduce risk to the project's revenue viability.
