Account For Proprietary Funds - CPA Far

SECTION 1

Historical Context & Motivation

Governmental accounting in the United States has long grappled with a fundamental tension: how should public entities account for activities that resemble private-sector business operations? For much of the twentieth century, state and local governments used a patchwork of accounting approaches that made it difficult to assess the true cost and financial performance of revenue-generating services such as water utilities, public transit systems, and municipal airports. The concept of proprietary funds emerged as the solution—a category of fund types designed to capture the economic substance of government activities that charge fees for services, mirroring the full accrual accounting framework used by for-profit enterprises.

The evolution of proprietary fund accounting reflects broader shifts in governmental accountability and transparency. Before the establishment of the Governmental Accounting Standards Board (GASB) in 1984, standards were set by the National Council on Governmental Accounting (NCGA), which began formalizing fund classifications in the mid-twentieth century. The push toward accrual-based reporting for business-type activities arose from citizen demands for clearer information about whether public utilities and services were financially self-sustaining or required subsidization from tax revenues.

1934 • Early Fund Classification

The National Committee on Municipal Accounting publishes early guidance distinguishing proprietary-type activities from governmental activities, laying the groundwork for separate fund categories.

1968 • NCGA Codification

The NCGA issues Governmental Accounting, Auditing and Financial Reporting (GAAFR), formally codifying enterprise and internal service fund types as proprietary fund categories.

1984 • GASB Established

The Governmental Accounting Standards Board is created under the Financial Accounting Foundation, assuming authority over state and local government accounting standards, including proprietary fund guidance.

1999 • GASB Statement No. 34

GASB 34 transforms governmental financial reporting by requiring government-wide financial statements on an accrual basis and refining proprietary fund reporting with three required financial statements.

2010–Present • Ongoing Refinements

Subsequent GASB pronouncements (e.g., GASB 62, 63, 65) continue to refine revenue recognition, deferred inflows/outflows, and net position classifications for proprietary funds.

The central question that proprietary fund accounting addresses is both practical and philosophical: when a government operates activities that function like a business—charging customers for water, electricity, or parking—should those activities be measured using the same economic resources measurement focus and accrual basis that private companies use? The answer, as codified under GASB standards, is unequivocally yes. This framework enables stakeholders to evaluate whether fee-supported services are covering their full costs, including depreciation and long-term liabilities, rather than masking true costs behind modified accrual conventions.

SECTION 2

Core Principles & Definitions

Proprietary funds occupy a distinctive position within the governmental fund structure. While governmental funds (such as the General Fund and Special Revenue Funds) use the modified accrual basis and current financial resources measurement focus, proprietary funds adopt the economic resources measurement focus and the full accrual basis of accounting. This means all assets and liabilities—both current and long-term—are recognized, revenues are recorded when earned, and expenses are recognized when incurred, regardless of when cash changes hands.

Enterprise Funds

Used for activities where the government charges external users (citizens, businesses) for goods or services. Examples include water/sewer utilities, airports, toll roads, and public transit. Required when outstanding debt is secured solely by fees, when cost recovery through fees is legally mandated, or when the government's policy is to set fees to cover costs including depreciation.

Internal Service Funds

Used for activities where one department provides goods or services to other departments or agencies within the same government (or to other governments) on a cost-reimbursement basis. Common examples include central motor pools, IT departments, risk management (self-insurance), and centralized printing services.

Economic Resources Measurement Focus

All economic resources (both current and non-current) are measured. Capital assets are reported and depreciated, long-term liabilities are recognized, and the statement of net position presents a comprehensive financial picture comparable to a corporate balance sheet.

Full Accrual Basis

Revenues are recognized when earned (e.g., when water is delivered), not when cash is collected. Expenses—including depreciation, amortization, and accrued interest—are recognized when incurred, not when paid. This matches GAAP for business enterprises under FASB guidance.

Three Required Financial Statements

Proprietary funds must present a Statement of Net Position (balance sheet equivalent), a Statement of Revenues, Expenses, and Changes in Net Position (income statement equivalent), and a Statement of Cash Flows using the direct method.

✦

KEY TAKEAWAY

Think of proprietary funds as the government's way of putting on a "private-sector hat." Just as a corporation tracks revenue, expenses, depreciation, and long-term debt to evaluate profitability, a municipal water utility uses proprietary fund accounting to determine whether customer fees fully cover the cost of delivering clean water—including the wear and tear on pipes and treatment facilities. If governmental funds are like tracking your monthly cash flow in a checking account, proprietary funds are like preparing a full personal financial statement with all your assets, debts, and net worth.

SECTION 3

Visual Explanation — Fund Structure Overview

Understanding where proprietary funds fit within the larger governmental fund taxonomy is essential. The following diagram illustrates the three major fund categories—governmental, proprietary, and fiduciary—and highlights the two proprietary fund types alongside their measurement focus and basis of accounting.

The diagram above illustrates the three fund categories in governmental accounting. Proprietary funds (center, in cyan) include Enterprise Funds that serve external users and Internal Service Funds that serve other departments. Both use full accrual accounting and economic resources measurement focus, distinguishing them from modified accrual governmental funds.

Notice that proprietary funds share the accrual basis with fiduciary funds, but the critical distinction lies in purpose: fiduciary funds hold resources in a trustee or custodial capacity for parties outside the government, while proprietary funds account for the government's own business-type and internal service operations. For CPA FAR exam purposes, always remember that enterprise funds report in the business-type activities column of the government-wide statements, while internal service funds are typically rolled into the governmental activities column because their predominant customers are usually other governmental departments.

SECTION 4

How Proprietary Fund Accounting Works

The mechanics of proprietary fund accounting closely parallel commercial enterprise accounting, though certain governmental nuances apply. Understanding the key equations, revenue/expense classifications, and net position categories is fundamental to mastering this topic for the CPA FAR exam.

The Accounting Equation for Proprietary Funds

PROPRIETARY FUND ACCOUNTING EQUATION

Assets + Deferred Outflows of Resources = Liabilities + Deferred Inflows of Resources + Net Position

This expanded equation reflects GASB requirements. Deferred outflows represent consumption of net assets applicable to a future period (e.g., pension-related deferrals). Deferred inflows represent acquisition of net assets applicable to a future period.

Net Position Categories

NET POSITION COMPONENTS

Net Position = Net Investment in Capital Assets + Restricted + Unrestricted

Net Investment in Capital Assets = Capital assets, net of depreciation, minus outstanding debt attributable to those assets plus any unspent proceeds. Restricted = Resources constrained by external parties (creditors, grantors, laws). Unrestricted = Residual amount; may be designated by management but not externally restricted.

Revenue & Expense Classification

A critical distinction in proprietary fund accounting is the classification of revenues and expenses as operating versus nonoperating. GASB does not provide a single bright-line definition; instead, the government must establish and consistently apply a policy. Generally, operating revenues derive from the fund's principal ongoing operations (e.g., water charges for an enterprise fund), while nonoperating items include interest revenue, interest expense, grants, capital contributions, and gains or losses on asset disposals. Distinguishing operating from nonoperating items is heavily tested on the CPA exam.

CHANGE IN NET POSITION

Change in Net Position = Operating Revenues − Operating Expenses + Nonoperating Revenues − Nonoperating Expenses + Capital Contributions + Transfers

Capital contributions include grants restricted for capital purposes, developer contributions, and tap fees. Transfers are flows between funds without a requirement for repayment.

Statement of Cash Flows — Direct Method

Unlike private-sector entities that may choose between the direct and indirect methods, GASB requires proprietary funds to use the direct method for the statement of cash flows. Additionally, governmental proprietary fund cash flows are classified into four categories—not three as in commercial accounting. The four categories are: (1) operating activities, (2) noncapital financing activities, (3) capital and related financing activities, and (4) investing activities. Interest paid on revenue bonds for capital assets falls under capital and related financing activities, while transfers from the General Fund to subsidize operations appear under noncapital financing activities.

💡

CPA EXAM TIP

Remember the mnemonic ONCI for the four cash flow categories in governmental proprietary funds: Operating, Noncapital financing, Capital and related financing, and Investing. The commercial FASB format uses only three categories (Operating, Investing, Financing), so the split of financing into noncapital and capital is a key governmental distinction.

SECTION 5

Detailed Breakdown — Enterprise vs. Internal Service Funds

While enterprise funds and internal service funds share the same accounting basis, they differ substantially in their purpose, reporting treatment, and the criteria for their use. The following diagram provides a side-by-side comparison of these two proprietary fund types, emphasizing the nuances that are frequently tested on the CPA FAR exam.

A side-by-side comparison of Enterprise Funds (left, blue) and Internal Service Funds (right, violet). Note that while both use identical accounting mechanics, their government-wide reporting treatment differs—enterprise funds map to business-type activities, while internal service funds typically consolidate into governmental activities.

Major Fund Determination for Enterprise Funds

Under GASB 34, an individual enterprise fund is reported as a major fund if it meets both the 5% and 10% criteria. First, total assets plus deferred outflows, liabilities plus deferred inflows, revenues, or expenses must be at least 5% of the corresponding totals for all governmental and enterprise funds combined. Second, the same element must be at least 10% of the corresponding total for all enterprise funds alone. Any enterprise fund not meeting these thresholds is aggregated into "Other Enterprise Funds." The government may also designate any fund as major if it believes separate presentation is important for user decision-making. Internal service funds, however, are never reported as major funds; they are presented in a single aggregated column in the proprietary fund statements.

SECTION 6

Worked Example — Enterprise Fund Transactions

The City of Riverdale operates a Water Utility Enterprise Fund. During fiscal year 2024, the following transactions occurred. We will record each transaction and then trace the effects through the three required financial statements.

City of Riverdale Water Utility Enterprise Fund — FY 2024

1
Step 1 — Record Water Service Revenue

During the year, the utility billed customers $4,200,000 for water services. Of this, $3,900,000 was collected in cash and $300,000 remains as accounts receivable at year end. Under accrual accounting, the full $4,200,000 is recognized as operating revenue when the water is delivered.

Dr. Cash $3,900,000; Dr. Accounts Receivable $300,000; Cr. Operating Revenue — Water Sales $4,200,000
2
Step 2 — Record Operating Expenses

Operating expenses for the year totaled $3,500,000, including wages ($1,800,000), chemicals and supplies ($600,000), contractual services ($400,000), and depreciation ($700,000). All except depreciation were paid in cash.

Dr. Operating Expenses $3,500,000; Cr. Cash $2,800,000; Cr. Accumulated Depreciation $700,000
3
Step 3 — Record Revenue Bond Issuance

The utility issued $5,000,000 in revenue bonds at par to finance a water treatment plant expansion. Bond proceeds are restricted for capital purposes. Under full accrual accounting, the bonds payable are recognized as a long-term liability.

Dr. Cash — Restricted $5,000,000; Cr. Revenue Bonds Payable $5,000,000
4
Step 4 — Record Capital Asset Acquisition and Interest

The utility spent $4,500,000 of bond proceeds on the treatment plant expansion (capitalized as a capital asset) and paid $200,000 in interest on the revenue bonds. Interest is classified as a nonoperating expense because it is not directly related to service delivery operations.

Capital Asset Entry: Dr. Capital Assets $4,500,000; Cr. Cash — Restricted $4,500,000. Interest Entry: Dr. Nonoperating Expense — Interest $200,000; Cr. Cash $200,000
5
Step 5 — Record Capital Contribution from Developer

A developer contributed water infrastructure (pipes, hydrants) valued at $350,000 as a condition of subdivision approval. This is recognized as a capital contribution—reported below the nonoperating section on the Statement of Revenues, Expenses, and Changes in Net Position.

Dr. Capital Assets — Infrastructure $350,000; Cr. Capital Contributions $350,000
6
Step 6 — Compute Change in Net Position

Operating Income = $4,200,000 − $3,500,000 = $700,000. Nonoperating Expense (net) = $200,000 interest. Capital Contributions = $350,000. Change in Net Position = $700,000 − $200,000 + $350,000 = $850,000. This increase flows to the Statement of Net Position, increasing unrestricted and net investment in capital assets categories.

Change in Net Position = $850,000 increase

ℹ

KEY OBSERVATION

Notice that the revenue bonds payable ($5,000,000) appear as a long-term liability on the Statement of Net Position—something that would not occur in a governmental fund using modified accrual. Similarly, the capital assets are reported at historical cost net of accumulated depreciation, providing users with the full economic picture of the utility's financial position.

SECTION 7

Proprietary Funds vs. Governmental Funds — Key Differences

One of the most heavily tested areas on the CPA FAR exam is the ability to distinguish how identical transactions are treated differently across fund types. The following table contrasts proprietary fund accounting with governmental fund accounting across critical dimensions.

Dimension	Proprietary Funds	Governmental Funds
Measurement Focus	Economic resources (all assets and liabilities)	Current financial resources (current assets and current liabilities)
Basis of Accounting	Full accrual	Modified accrual
Capital Assets	Capitalized and depreciated; reported on Statement of Net Position	Not reported in fund statements; recorded as expenditures when purchased
Long-Term Debt	Reported as liabilities on Statement of Net Position	Not reported in fund statements; proceeds recorded as other financing sources
Revenue Recognition	When earned	When measurable and available (typically within 60 days of year-end)
Expense/Expenditure	Expenses recognized when incurred (including depreciation)	Expenditures recognized when fund liability is incurred and due
Balance Sheet Equity	Net Position (3 categories)	Fund Balance (5 categories: nonspendable, restricted, committed, assigned, unassigned)
Cash Flow Statement	Required (direct method, four categories)	Not required

Key accounting differences between proprietary and governmental funds

✦

KEY TAKEAWAY

The essential distinction can be understood through an analogy to personal finance. Governmental fund accounting is like tracking only what's in your checking account and what bills are due this month—a snapshot of near-term spendable resources. Proprietary fund accounting is like preparing a comprehensive personal net-worth statement that includes the current value of your house (net of the mortgage), your retirement accounts, your car (net of the auto loan), and all other assets and liabilities. Both views are useful, but the proprietary approach gives a complete economic picture that enables stakeholders to assess long-term sustainability.

SECTION 8

Connection to Government-Wide Statements & Advanced Issues

Proprietary fund accounting does not exist in isolation; it connects directly to the government-wide financial statements required by GASB 34. The government-wide Statement of Net Position and Statement of Activities present all governmental and business-type activities on the accrual basis. Because proprietary funds already use accrual accounting, their data requires minimal conversion for incorporation into government-wide statements. By contrast, governmental fund data must undergo significant adjustments—adding back capital assets, removing current-year capital expenditures, recognizing long-term liabilities, and adjusting for modified accrual timing differences.

Topic	Proprietary Fund Level	Government-Wide Level
Enterprise Funds	Reported individually (if major) or in aggregate	Rolled into Business-Type Activities column
Internal Service Funds	Reported in a single aggregated column	Typically consolidated into Governmental Activities column; interfund balances eliminated
Interfund Transactions	Reported as interfund receivables/payables, transfers, and internal charges	Reciprocal interfund balances eliminated; internal service profits/losses adjusted
Conversion Adjustments	Minimal—already on accrual basis	ISF profits removed to avoid double-counting; markup over cost is backed out

Proprietary fund data at fund level vs. government-wide level

Internal Service Fund Elimination Issues

A particularly nuanced topic involves internal service fund profit elimination. When an ISF charges governmental funds a markup above cost—for instance, a central motor pool that charges departments 10% above its actual fleet costs—the overcharge inflates governmental fund expenditures and creates an artificial profit in the ISF. At the government-wide level, this internal profit must be eliminated so that governmental activities expenses reflect actual costs, not inflated interdepartmental billings. This elimination appears as an adjustment on the reconciliation schedule between fund-level and government-wide statements, a topic that surfaces regularly in CPA FAR exam simulations.

GASB 87 — Leases and Proprietary Funds

Recent GASB pronouncements continue to affect proprietary fund reporting. GASB Statement No. 87 on leases requires proprietary funds to recognize a right-to-use lease asset and a lease liability for most leases with terms exceeding 12 months. This parallels the FASB ASC 842 model for private companies but uses a single-model approach (all leases are treated similarly). Additionally, GASB 96 addresses subscription-based information technology arrangements (SBITAs), requiring recognition of an intangible right-to-use asset and a corresponding liability—particularly relevant for internal service funds providing IT services.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

A city operates a municipal parking garage that charges the public hourly and monthly fees. The garage's outstanding debt is secured solely by parking revenues. Which fund type should be used to account for the parking garage operations, and why?

Show answer

The parking garage should be reported in an enterprise fund. Under GASB standards, an enterprise fund is required when outstanding debt for an activity is secured solely by a pledge of the net revenues from fees and charges of the activity. Since the parking garage debt is secured exclusively by parking revenues—not general tax revenues—the enterprise fund requirement is triggered. Additionally, the garage charges external users (the public) for services, which aligns with the fundamental purpose of enterprise funds. The enterprise fund will use full accrual accounting, capitalize the garage structure and equipment, depreciate those assets, and recognize all long-term liabilities including the revenue bonds.

Question 2: BASIC CALCULATION

A government's water enterprise fund reports the following for FY 2024: water service charges billed $6,000,000; operating expenses including depreciation of $800,000 total $5,200,000; interest expense on revenue bonds $180,000; investment income $45,000; capital contributions from developers $275,000. Calculate the change in net position for the year.

Show answer

The change in net position is calculated as follows: Operating Income = Operating Revenues ($6,000,000) − Operating Expenses ($5,200,000) = $800,000. Nonoperating Revenues (Expenses) = Investment Income ($45,000) − Interest Expense ($180,000) = −$135,000. Income Before Capital Contributions = $800,000 − $135,000 = $665,000. Add Capital Contributions of $275,000. Change in Net Position = $665,000 + $275,000 = $940,000 increase. Note that interest expense is classified as nonoperating, investment income is nonoperating revenue, and capital contributions appear below the nonoperating section on the Statement of Revenues, Expenses, and Changes in Net Position.

Question 3: INTERMEDIATE

A county's internal service fund (Central Motor Pool) charges county departments $2,400,000 for vehicle usage during FY 2024. The ISF's actual operating costs are $2,100,000 (including $350,000 depreciation on vehicles). When preparing government-wide financial statements, what adjustment is needed, and in which activities column does the ISF appear?

Show answer

The Central Motor Pool ISF is typically consolidated into the governmental activities column of the government-wide statements because its predominant customers are county departments (governmental funds). The ISF generated a $300,000 profit ($2,400,000 charges minus $2,100,000 costs). At the government-wide level, this $300,000 internal profit must be eliminated because it represents an overcharge to governmental departments—the governmental activities expenses were inflated by $300,000 beyond actual economic cost. The elimination reduces governmental activities expenses by $300,000 and reduces the ISF's net position by the same amount in the consolidation. This ensures the government-wide statements reflect the true cost of services rather than artificially inflated interdepartmental billings. The reconciliation between fund-level and government-wide statements will include this adjustment.

Question 4: APPLIED

The City of Lakewood's Electric Utility Enterprise Fund issues $10,000,000 in revenue bonds at 101 (a 1% premium) to finance a new power substation. During the year, the city spends $8,500,000 on the substation (placed in service), pays $400,000 in bond interest, and receives $150,000 in interest on temporarily invested bond proceeds. Prepare the journal entries and classify each item for the Statement of Cash Flows.

Show answer

Journal entries: (1) Bond issuance: Dr. Cash $10,100,000; Cr. Revenue Bonds Payable $10,000,000; Cr. Premium on Bonds Payable $100,000. Cash flow classification: Capital and Related Financing Activities—inflow of $10,100,000. (2) Substation construction: Dr. Capital Assets—Power Substation $8,500,000; Cr. Cash $8,500,000. Cash flow classification: Capital and Related Financing Activities—outflow of $8,500,000. (3) Bond interest payment: Dr. Interest Expense $400,000; Cr. Cash $400,000. Cash flow classification: Capital and Related Financing Activities—outflow of $400,000 (interest on debt related to capital assets). (4) Investment income: Dr. Cash $150,000; Cr. Investment Revenue $150,000. Cash flow classification: Investing Activities—inflow of $150,000. The premium on bonds payable will be amortized over the bond term as a reduction of interest expense. On the Statement of Net Position, the $100,000 premium increases the total bonds payable reported. The substation is reported in capital assets at $8,500,000 and will be depreciated over its useful life.

Question 5: CRITICAL THINKING

A state government's Department of Information Technology (DoIT) provides services to both state agencies (75% of revenue) and county governments (25% of revenue). Management is debating whether to classify DoIT as an internal service fund or an enterprise fund. Discuss the factors that should guide this decision, the financial reporting implications of each choice, and how the classification affects government-wide financial statement presentation.

Show answer

The classification decision hinges on who the predominant customers are and the activity's purpose. Since 75% of DoIT's revenue comes from internal state agencies, the internal service fund classification appears most appropriate—ISFs are designed for activities whose predominant customers are other departments of the same government. However, the 25% external revenue from counties introduces complexity. If DoIT were classified as an ISF, it would appear in a single aggregated column in the proprietary fund financial statements and would typically be consolidated into the governmental activities column at the government-wide level (since governmental funds are the predominant customers). Internal profits would need to be eliminated. If instead classified as an enterprise fund, DoIT would appear in the business-type activities column at the government-wide level and could be reported as a major fund if it meets the 5%/10% criteria. The charges to state agencies would then appear as interfund transactions rather than internal activity. GASB does not prescribe a bright-line percentage for determining predominant customers, but the 75%/25% split strongly favors ISF treatment. Management should also consider whether any outstanding DoIT debt is secured solely by its fee revenues (which would mandate enterprise fund treatment) and whether legal provisions require full cost recovery. The best practice is to document the rationale in the notes to financial statements, as auditors will evaluate whether the classification fairly presents the activity's economic substance.

SUMMARY

Lesson Summary

Summary

Proprietary funds serve as the governmental accounting framework for activities that operate like businesses. The two types—enterprise funds (serving external customers) and internal service funds (serving other departments)—both employ the economic resources measurement focus and the full accrual basis of accounting. This means all assets (including capital assets reported at cost less accumulated depreciation) and all liabilities (including long-term debt) are recognized, revenues are recorded when earned, and expenses are recorded when incurred.

Three financial statements are required: the Statement of Net Position, the Statement of Revenues, Expenses, and Changes in Net Position, and the Statement of Cash Flows using the direct method with four cash flow categories (ONCI). At the government-wide level, enterprise funds are reported under business-type activities while internal service funds typically consolidate into governmental activities, with any internal profits eliminated to prevent double-counting. Mastering the distinction between operating versus nonoperating items, proper classification of capital contributions, and the three net position categories is essential for CPA FAR exam success.
