1.3 Subnational Governments: General-Purpose vs. Special-Purpose

Subnational Governments: General-Purpose vs. Special-Purpose

The U.S. Census of Governments classifies approximately 90,000 subnational governmental units into two broad categories: general-purpose governments and special-purpose governments.

The Proliferation of Special Districts

Special districts represent the most rapidly growing segment of local government in the United States. They are created for several key fiscal and administrative reasons:

• Bypassing Constitutional Debt and Tax Limits: States frequently impose constitutional or statutory caps on municipal and county property tax rates and outstanding general obligation debt. Establishing a separate special district creates a distinct legal entity with its own independent borrowing and taxing capacity.
• Aligning Service Boundaries with Physical Needs: Natural or functional service areas (such as river watersheds, transit corridors, or fire protection zones) rarely align with arbitrary historical municipal or county borders. Special districts bridge multiple municipal boundaries.
• Benefit-Based Financing: Ensures that only residents or properties directly benefiting from a specialized infrastructure project (e.g., irrigation, drainage, public transit) pay for its capital and operational costs through targeted assessments or user fees.
• Depoliticized, Professional Management: Insulates technical utility operations (such as water purification or hazardous waste management) from municipal political pressures.

Quasi-Governmental Entities, Public Authorities, and GSEs

Beyond standard general-purpose and special-purpose governments, public administration utilizes hybrid organizational forms designed to blend public accountability with private-sector operational flexibility.

Government Corporations

Government corporations are wholly or partially owned public enterprises created by statute to deliver market-oriented commercial services to the public. Prominent examples include the United States Postal Service (USPS), the Federal Deposit Insurance Corporation (FDIC), the Tennessee Valley Authority (TVA), the Pension Benefit Guaranty Corporation (PBGC), and the National Railroad Passenger Corporation (Amtrak).

Under the Government Corporation Control Act of 1945 (GCCA) (31 U.S.C. §§ 9101–9110), federal government corporations are subject to specific budgetary and accountability controls. They must submit annual business-type budget programs to OMB and the President, maintain commercial-style accrual accounting systems, and undergo annual independent financial audits.

Public Authorities

At the state and local levels, public authorities (often designated as public benefit corporations, commissions, or boards) are created by state enabling legislation to finance, construct, and operate revenue-producing public capital assets (such as toll turnpikes, airports, maritime ports, bridges, and convention centers). Examples include the Port Authority of New York and New Jersey and the Pennsylvania Turnpike Commission.

The defining fiscal characteristic of a public authority is its reliance on revenue bonds. Revenue bonds are secured exclusively by the earnings of the enterprise (e.g., bridge tolls, airport landing fees, parking surcharges). Because they are non-recourse to the state or municipal general tax fund, revenue bonds do not constitute full faith and credit debt, do not require voter referendum approval in most jurisdictions, and do not count against general constitutional municipal debt ceilings.

Government-Sponsored Enterprises (GSEs)

Government-Sponsored Enterprises are privately owned, publicly chartered financial institutions established by Congress to enhance liquidity and reduce capital costs in targeted economic sectors, primarily housing and agriculture. Major GSEs include the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corporation (Freddie Mac), and the Federal Home Loan Bank System.

Although chartered with public missions, GSEs are owned by private shareholders or member cooperatives. GSE debt securities are not explicit obligations of the U.S. government, nor are they backed by the full faith and credit of the Treasury. Financial markets historically priced an expectation of federal support. In 2008, Fannie Mae and Freddie Mac entered FHFA conservatorship and received entity-specific Treasury support through preferred stock purchase agreements; those actions did not convert every GSE obligation into debt backed by the full faith and credit of the United States.

Jointly Governed Organizations

Jointly governed organizations are regional bodies created through intergovernmental agreements or compacts between two or more local governments to manage shared regional assets (e.g., regional councils of government, joint transit authorities like the Washington Metropolitan Area Transit Authority - WMATA). Under GASB Statement No. 14 (as amended by GASB Statement No. 61), an entity is classified as a jointly governed organization if it is governed by representatives of the participating governments but no participating government retains an ongoing financial interest or ongoing financial burden. As such, they are not reported as component units on the financial statements of participating municipalities, requiring only note disclosure.

Practical Public Finance Scenario: Financing Regional Water Infrastructure

To analyze how these public entity structures operate in capital financing, consider the following scenario:

Scenario: The City of Fairview and neighboring Jackson County experience rapid population growth, resulting in severe regional wastewater capacity deficits. Expanding the existing municipal treatment plant will cost $360 million. Fairview's municipal general obligation (GO) debt is currently at 91% of its constitutional debt limit, and state law requires a 60% supermajority voter referendum for any new municipal GO bond issuance—a threshold that failed in two prior elections. Jackson County faces similar fiscal constraints.

Professional Financial Analysis

1. Creation of an Independent Public Authority: Rather than funding the capital asset through general municipal debt, the city council and county commission utilize state enabling legislation to jointly charter the Fairview-Jackson Regional Clean Water Authority as an independent special-purpose public authority.
2. Issuance of Revenue Bonds: The newly formed Authority issues $360 million in 30-year water and sewer revenue bonds. The debt is secured solely by net system utility revenues generated from customer water and sewer billings. The bond indenture includes:
   • A Rate Covenant: The Authority legally pledges to establish and maintain user rates sufficient to generate net revenues equal to at least 1.25 times annual debt service (125% Debt Service Coverage Ratio - DSCR).
   • A Flow of Funds Structure: Gross utility revenues must flow sequentially through designated accounts: (1) Operating & Maintenance (O&M) Fund, (2) Debt Service Sinking Fund, (3) Debt Service Reserve Fund (DSRF), (4) Renewal & Replacement Fund, and (5) General Surplus Fund.
3. Debt Limit and Financial Reporting Insulation: Because the revenue bonds are not backed by the full faith, credit, or taxing powers of Fairview or Jackson County, the debt does not count against either jurisdiction's constitutional debt ceiling and requires no public referendum. Furthermore, under GASB standards, because the Authority sets its own rates and neither general-purpose government is obligated to subsidize deficits, the Authority is reported as an independent special-purpose government rather than a blended component unit.
