General Obligation (GO) Bonds

General Obligation bonds are backed by the full faith and credit and taxing power of the issuing municipality. They are considered the safest type of municipal bond because the issuer pledges its entire taxing authority to repay bondholders.

How GO Bonds Are Secured

GO bonds are backed by ad valorem taxes—property taxes based on the assessed value of real estate within the municipality's jurisdiction.

Ad Valorem Tax

  • "Ad valorem" means "according to value"
  • Property owners pay taxes based on the assessed value of their property
  • The municipality can raise property taxes to pay bondholders if needed

Types of GO Bonds

Unlimited Tax GO Bonds (UTGO)

The stronger security pledge.

FeatureDescription
Tax AuthorityNo limit on property tax rates
SecurityIssuer can raise taxes as high as needed
Voter ApprovalUsually required
Credit QualityGenerally higher rated

Exam Tip: "Unlimited" means unlimited taxing power—the municipality can raise property taxes without limit to pay bondholders.


Limited Tax GO Bonds (LTGO)

A more restricted pledge.

FeatureDescription
Tax AuthorityTax rate or amount is capped
SecurityIssuer cannot exceed the statutory limit
Voter ApprovalOften not required
Credit QualityMay be rated slightly lower than UTGO

Millage Limits:

  • Limits are often expressed in "mills" (1 mill = 0.1% or $1 per $1,000 of assessed value)
  • Example: A 10-mill limit means maximum tax of $10 per $1,000 of assessed value

GO Bond Credit Analysis

When analyzing GO bond creditworthiness, consider:

Economic Factors

  • Population trends (growing or declining?)
  • Employment diversity (one major employer vs. diversified economy)
  • Property values and tax base trends
  • Per capita income levels

Debt Factors

  • Total debt outstanding
  • Debt per capita
  • Debt as percentage of assessed property value
  • Overlapping debt (debt from other jurisdictions)

Administrative Factors

  • Quality of financial management
  • Budgeting practices
  • History of balanced budgets
  • Tax collection rates

Double-Barreled Bonds

Some bonds are secured by both a specific revenue source AND the full faith and credit of the issuer.

Example: A school district bond backed by:

  • Revenue from state education aid
  • The district's GO pledge (property taxes)

These are called double-barreled bonds because they have two sources of repayment.


Voter Approval Requirements

Bond TypeVoter Approval
Unlimited Tax GOUsually required
Limited Tax GOOften not required
Revenue BondsTypically not required

Key Point: The need for voter approval can delay issuance of UTGO bonds, but it also signals strong public support for the project.
