SECTION 1
Historical Context & Motivation
Governments frequently hold resources that do not belong to them — pension contributions for employees, taxes collected on behalf of other jurisdictions, and investment pools administered for external participants. Historically, accounting for these fiduciary activities varied widely among jurisdictions, creating opacity that undermined public trust and complicated external auditing. The need to segregate assets held in a fiduciary capacity from a government's own resources became a central concern as state and local governments grew in fiscal complexity during the twentieth century.
As public pension systems expanded after the Second World War, the sheer volume of assets held in trust — often exceeding a government's own net position — demanded a formal reporting framework. Without such a framework, the risk of commingling fiduciary assets with governmental resources was significant, and stakeholders lacked the information necessary to evaluate a government's stewardship of entrusted resources. The evolution of standards governing fiduciary funds reflects a broader movement toward transparency and accountability in governmental financial reporting.

The central question that fiduciary fund accounting resolves is this: How should a government report resources it controls but does not own, ensuring that users of financial statements can distinguish between a government's own net position and assets it merely holds as a trustee or custodian? Understanding the answer to this question is essential for CPA candidates preparing for the FAR section, as fiduciary funds appear prominently in state and local government reporting problems.
SECTION 2
Core Principles & Definitions
At their core, fiduciary funds capture the accounting for assets that a government holds in a trust or custodial capacity for individuals, private organizations, or other governments. Because these resources do not belong to the reporting government, they are excluded from the government-wide financial statements and appear only in the fiduciary fund financial statements. This exclusion is a fundamental principle: fiduciary net position is not available to finance the government's own programs.
Pension (and OPEB) Trust Funds
Investment Trust Funds
Private-Purpose Trust Funds
Custodial Funds
A critical distinction for CPA candidates involves the identification criteria under GASB 84. A government's activity is fiduciary if the assets are (a) administered through a trust in which the government is not a beneficiary, (b) the government controls the assets and the assets are derived from sources other than the government's own revenues, or (c) the government controls the assets and the assets are for the benefit of individuals, organizations, or other governments not part of the reporting entity. GASB 84's criteria replaced the older, less precise guidance and eliminated much of the judgment previously required.

Visual Explanation — Fiduciary Fund Reporting Structure
The diagram below illustrates the relationship between fiduciary fund financial statements and the broader governmental reporting model. Note that the government-wide statements exclude fiduciary activities entirely. Fiduciary funds produce two required statements: a Statement of Fiduciary Net Position and a Statement of Changes in Fiduciary Net Position. These are presented using the economic resources measurement focus and accrual basis of accounting.
SECTION 4
Accounting Mechanics — Measurement Focus & Basis of Accounting
All fiduciary funds use the economic resources measurement focus and the accrual basis of accounting. This means that all assets and liabilities — both current and long-term — are reported on the Statement of Fiduciary Net Position. Revenues (called 'additions' in fiduciary terminology) are recognized when earned, and expenses (called 'deductions') are recognized when the related liability is incurred, regardless of the timing of cash flows. This treatment parallels proprietary fund accounting and stands in contrast to the modified accrual basis used for governmental funds.
Key Accounting Equation
FIDUCIARY NET POSITION
Assets include cash, investments at fair value, receivables, and capital assets held in trust. Liabilities include benefits payable, refunds payable, and amounts due to other entities. Net position is restricted to the fiduciary purpose — it is not classified as restricted, unrestricted, or invested in capital assets like in government-wide statements.
CHANGE IN FIDUCIARY NET POSITION
Additions include contributions from employers, plan members, and other entities, plus investment income (including unrealized gains and losses). Deductions include benefit payments, refunds, and administrative expenses. This equation drives the Statement of Changes in Fiduciary Net Position.
Journal Entry Mechanics
Journal entries for fiduciary funds follow standard double-entry conventions but use account titles tailored to the fiduciary context. When a pension trust fund receives employer contributions, the entry debits Cash and credits Additions — Employer Contributions. When benefits are paid, the entry debits Deductions — Benefit Payments and credits Cash. Investments are reported at fair value, so unrealized gains and losses are recognized through the additions account — this is a key distinction from the historical-cost model used in many private-sector contexts.

Detailed Breakdown — The Four Fiduciary Fund Types
While all four fiduciary fund types share the same measurement focus and basis of accounting, they differ significantly in the nature of the activities they report, the source of their assets, and the identity of their beneficiaries. GASB Statement No. 84 provides a structured decision framework to determine (a) whether an activity is fiduciary and (b) which fund type is appropriate. The table below summarizes the key characteristics, and the diagram that follows illustrates the decision logic prescribed by GASB 84.
| Fund Type | Trust Agreement? | Beneficiaries | Examples |
|---|---|---|---|
| Pension (& OPEB) Trust | Yes — qualifying trust per GASB 67/68/74/75 | Plan members and their beneficiaries | Defined benefit pension plan, OPEB trust, defined contribution plan |
| Investment Trust | Yes — trust or equivalent arrangement | External participants in government-sponsored investment pools | County investment pool (external portion), state-administered local government investment fund |
| Private-Purpose Trust | Yes — trust agreement | Individuals, private organizations, other governments | Escheat property, scholarship trust for non-government beneficiaries, unclaimed property |
| Custodial | No — no trust arrangement | Individuals, private organizations, other governments | Tax collections on behalf of other governments, special assessments collected for property owners, pass-through grants |
Summary of fiduciary fund types under GASB 84
A critical change introduced by GASB 84 was the elimination of the agency fund category. Under prior guidance, agency funds reported only assets and liabilities (Assets = Liabilities, with no net position and no statement of changes). The new custodial fund is broader in scope: it reports fiduciary net position and recognizes additions and deductions over the life of the activity. This represents a significant improvement in transparency, as stakeholders can now see the flow of resources through custodial arrangements over time, not merely a snapshot of balances.

Worked Example — Recording Fiduciary Fund Transactions
The City of Greenfield administers a defined benefit pension trust fund and a custodial fund for property tax collections on behalf of the county government. During fiscal year 2024, the following transactions occur. We will record the journal entries and prepare condensed financial statements for each fund.
Pension Trust Fund — City of Greenfield
- 1
Step 1 — Record Employer Contributions Received
The city contributes $5,000,000 to the pension trust fund based on the actuarially determined contribution (ADC). The entry is: Dr. Cash $5,000,000 Cr. Additions — Employer Contributions $5,000,000 This increases both the fund's cash balance and its net position through the additions account.Cash ↑ $5,000,000 | Additions ↑ $5,000,000 - 2
Step 2 — Record Employee Contributions Received
Employees contribute $2,000,000 through payroll withholdings transferred to the trust. The entry is: Dr. Cash $2,000,000 Cr. Additions — Employee Contributions $2,000,000Cash ↑ $2,000,000 | Additions ↑ $2,000,000 - 3
Step 3 — Record Net Investment Income and Unrealized Gains
The trust portfolio earns $800,000 in dividends and interest, plus $1,200,000 in unrealized appreciation (fair value increase). Under the accrual basis, both are recognized: Dr. Cash $800,000 Dr. Investments $1,200,000 Cr. Additions — Net Investment Income $2,000,000 Note that unrealized gains are reported through the additions line, not deferred.Cash ↑ $800,000 | Investments ↑ $1,200,000 | Additions ↑ $2,000,000 - 4
Step 4 — Record Benefit Payments to Retirees
The fund pays $4,500,000 in monthly retirement benefits to plan participants: Dr. Deductions — Benefit Payments $4,500,000 Cr. Cash $4,500,000 Deductions reduce fiduciary net position.Cash ↓ $4,500,000 | Deductions ↑ $4,500,000 - 5
Step 5 — Record Administrative Expenses
The fund incurs $150,000 in administrative costs (investment management fees, actuarial services): Dr. Deductions — Administrative Expenses $150,000 Cr. Cash $150,000Cash ↓ $150,000 | Deductions ↑ $150,000 - 6
Step 6 — Calculate Change in Fiduciary Net Position
Total Additions = $5,000,000 + $2,000,000 + $2,000,000 = $9,000,000 Total Deductions = $4,500,000 + $150,000 = $4,650,000 Change in Net Position = $9,000,000 − $4,650,000 = $4,350,000 If beginning fiduciary net position was $50,000,000, ending net position is $54,350,000.Ending Fiduciary Net Position = $54,350,000

Fiduciary Funds vs. Other Fund Categories
A frequent source of confusion on the CPA FAR exam is distinguishing fiduciary funds from governmental and proprietary funds, particularly because all three categories may hold resources for similar-sounding purposes. The table below draws out the critical differences across measurement focus, basis of accounting, financial statement presentation, and the nature of resources reported.
| Characteristic | Governmental Funds | Proprietary Funds | Fiduciary Funds |
|---|---|---|---|
| Measurement Focus | Current financial resources | Economic resources | Economic resources |
| Basis of Accounting | Modified accrual | Accrual | Accrual |
| Gov't-Wide Statements? | Yes (converted to accrual) | Yes | No — excluded |
| Revenue / Expense Terms | Revenues & Expenditures | Revenues & Expenses | Additions & Deductions |
| Resource Ownership | Government's own resources | Government's own resources | Held for external parties |
| Net Position Classification | Fund balance (5 categories) | Net invested in capital assets; restricted; unrestricted | Restricted (held in trust) or reported as fiduciary net position |

Connection to Advanced Reporting — GASB 67, 68, 74, & 75
Fiduciary fund accounting does not exist in isolation; it interconnects deeply with the employer-side pension and OPEB reporting requirements established by GASB Statements No. 67 and 68 (for pensions) and GASB Statements No. 74 and 75 (for OPEB). The pension trust fund's fiduciary net position directly feeds into the calculation of the employer's net pension liability (or asset) on the government-wide statements. This relationship means that the accuracy of fiduciary fund reporting has a direct impact on the employer's government-wide financial position.
| Concept | Fiduciary Fund Level (GASB 67/74) | Employer Level (GASB 68/75) |
|---|---|---|
| Plan Net Position | Reported on Statement of Fiduciary Net Position | Used as a component in calculating net pension liability |
| Total Pension Liability | Disclosed in plan's notes and RSI | Net Pension Liability = TPL − Plan Net Position |
| Discount Rate | Based on expected return on plan investments | Blended rate if plan net position is projected to be insufficient |
| Investment Income | Recognized in full as addition in fiduciary statements | Difference between actual and expected return creates deferred inflows/outflows |
| Financial Statements | Fiduciary fund statements only | Government-wide statements (net pension liability on Statement of Net Position) |
Interplay between fiduciary-level and employer-level pension/OPEB reporting
Understanding this linkage is particularly important for the CPA exam. Questions may require candidates to trace a pension plan's fiduciary net position from the fiduciary fund statements into the net pension liability calculation on the employer's government-wide statements. Additionally, GASB 84's identification criteria interact with component unit reporting: if a pension plan qualifies as a fiduciary component unit of the sponsoring government, it is blended into the government's fiduciary fund statements. Advanced study should also consider GASB Statement No. 97 (2020), which refined the treatment of certain Section 457 deferred compensation plans and clarified that certain IRC Section 457 plans meeting specific criteria should be reported as pension trust funds rather than custodial funds.

SUMMARY
Summary — Accounting for Fiduciary Funds
Summary
Fiduciary funds report resources a government holds in a trust or custodial capacity for external parties — pension plan participants, other governments, individuals, or private organizations. Under GASB Statement No. 84, four fund types exist: pension (and OPEB) trust funds, investment trust funds, private-purpose trust funds, and custodial funds. All four types use the economic resources measurement focus and the accrual basis of accounting, and all are excluded from the government-wide financial statements.
Fiduciary funds produce two required statements: the Statement of Fiduciary Net Position and the Statement of Changes in Fiduciary Net Position. Activity is measured through additions (contributions, investment income) and deductions (benefit payments, administrative expenses). A critical GASB 84 change was replacing the legacy agency fund with the broader custodial fund, which now recognizes a full statement of changes. Fiduciary net position — particularly in pension trust funds — links directly to the employer's net pension liability under GASB 68, making accurate fiduciary fund accounting essential for the integrity of the entire governmental reporting model.
