Proprietary Fund

A proprietary fund reports a government's business-type or internal service activities using accrual accounting and an economic resources focus.

A proprietary fund is a U.S. state or local government accounting fund used for business-type activities or services supplied internally to government departments. Proprietary funds use the economic resources measurement focus and accrual accounting, making their statements structurally closer to business financial statements than governmental fund statements are.

There are two proprietary fund types: enterprise funds and internal service funds. The classification does not guarantee that an activity is profitable, self-sufficient, or free from tax support.

Key Takeaways

  • Enterprise funds primarily serve the public; internal service funds primarily serve the reporting government’s departments.
  • Proprietary funds report capital assets, depreciation, and long-term liabilities within the fund statements.
  • Their required statements cover net position, revenues and expenses, changes in fund net position, and cash flows.
  • User charges matter, but subsidies, transfers, capital contributions, and debt financing can also be significant.
  • GASB Statement 103 changes operating and nonoperating presentation for fiscal years beginning after June 15, 2025.

Enterprise vs. Internal Service Funds

FeatureEnterprise fundInternal service fund
Primary customersGeneral public or external usersDepartments or agencies of the same government
Typical activitiesWater, sewer, transit, airport, or electric utilityFleet, information technology, insurance, or central purchasing
Reporting roleBusiness-type activityCost-reimbursement service within government
Major-fund presentationMajor enterprise funds shown separatelyInternal service funds generally combined in a separate column
Common analytical issueRate sufficiency and debt coverageAllocation method and whether charges approximate cost

An enterprise fund may be required when an activity is financed with debt secured solely by its net revenues, when laws or regulations require charges designed to recover costs, or when pricing policy is designed to recover costs. Exact classification depends on the applicable standards and facts.

Statements and Measurement Basis

Proprietary fund reporting uses the economic resources measurement focus and accrual basis. It therefore recognizes capital assets and long-term liabilities and reports expenses as resources are consumed, including depreciation.

The core statement relationship is:

$$ \text{Fund Net Position} = \text{Assets} + \text{Deferred Outflows} - \text{Liabilities} - \text{Deferred Inflows} $$

Required proprietary fund statements generally include:

  • a statement of net position;
  • a statement of revenues, expenses, and changes in fund net position; and
  • a statement of cash flows.

The cash flow statement is especially useful because accrual operating results do not show whether customer collections covered operating cash requirements or capital spending.

Current Presentation Under GASB Statement 103

For fiscal years beginning after June 15, 2025, GASB Statement 103 provides definitions for operating and nonoperating revenues and expenses and requires a subtotal for operating income or loss and noncapital subsidies before other nonoperating items.

This matters because the old presentation could vary with each government’s policy. Analysts comparing periods should check whether Statement 103 has been adopted and whether prior-period captions were reclassified.

The new subtotal still is not a universal measure of economic self-sufficiency. A fund may rely on capital subsidies, transfers, taxes, or other resources outside charges for services.

Worked Example

Suppose a municipal water enterprise fund reports:

ItemAmount
Charges for services$48 million
Operating expenses excluding depreciation($35 million)
Depreciation($8 million)
Operating income$5 million
Interest expense and other nonoperating items, net($3 million)
Capital contribution$6 million

The $5 million operating income indicates that recognized operating revenue exceeded operating expenses, including depreciation. It does not mean the fund generated $5 million of operating cash, nor does it show whether cash was sufficient for debt principal, construction, or reserve requirements.

The capital contribution increases net position but should not be mistaken for recurring customer revenue. An analyst would also inspect the statement of cash flows, debt covenants, rate policy, capital plan, and restricted assets.

How Analysts Evaluate a Proprietary Fund

  • Rate sufficiency: Do charges cover operating costs, debt service, and necessary reinvestment under the entity’s policy and legal framework?
  • Cash generation: Does operating cash flow support maintenance and capital needs?
  • Capital condition: Is depreciation materially below actual renewal requirements, or are assets aging faster than reinvestment?
  • Debt structure: What do bond covenants define as pledged revenue, operating expense, and coverage?
  • Subsidies and transfers: Are operating results dependent on recurring support from another fund or government?
  • Internal allocations: For internal service funds, are cost allocations reasonable, consistent, and free from material accumulated surpluses or deficits?

For a debt-financed utility, also review the governing Revenue Bond documents. Covenant calculations can differ from GAAP operating income.

Common Mistakes

  • Assuming user fees make the fund self-supporting: Charges may cover only part of costs, and subsidies or transfers may be material.
  • Equating operating income with cash flow: Accrual income includes noncash items and excludes some cash financing and capital flows.
  • Ignoring depreciation: Excluding depreciation may overstate the apparent economics of an asset-intensive service.
  • Treating net position as spendable cash: Net position can be invested in capital assets or restricted by external requirements.
  • Using GAAP income as bond coverage: Debt covenants often define revenues, expenses, and required deposits differently.
  • Governmental Fund: The current-resources category used mainly for tax-supported activities.
  • Fiduciary Fund: A fund for resources held for outside beneficiaries rather than the government’s own services.
  • Operating Income: A subtotal whose governmental proprietary-fund presentation is governed by GASB requirements.
  • Capital Expenditure: Cash investment that should be compared with depreciation and asset condition.
  • Accrual Accounting: The accounting basis used in proprietary fund statements.

FAQs

What are the two types of proprietary funds?

Enterprise funds provide goods or services mainly to the public or external users. Internal service funds provide goods or services mainly to departments or agencies within the same government.

Is a proprietary fund expected to earn a profit?

Not necessarily. The fund may have cost-recovery or policy objectives rather than a profit objective, and it may receive subsidies, transfers, or capital contributions.

Why does a proprietary fund report depreciation?

Its economic resources focus and accrual basis recognize the consumption of capital assets over their useful lives, unlike governmental fund statements that generally report capital acquisition as an expenditure.

Is proprietary fund net position the same as fund balance?

No. Fund net position is an economic-resources residual used in proprietary reporting. Fund balance is the current-financial-resources residual used in governmental funds.
