Accounting for Contributions in Aid of Construction Under GASB 33 and GASB 62

Contributions in Aid of Construction (CIAC) represent cash or property donated to a utility by developers, customers, or other third parties to fund the construction of utility infrastructure. For governmental utilities following GASB standards, CIAC presents an important accounting question: how do you recognize a contribution that funds a capital asset — and does regulatory accounting offer a better approach?

The answer depends on whether your utility applies GASB 33 alone or combines it with the regulatory accounting provisions of GASB 62. Both approaches are valid, but they produce meaningfully different financial statement outcomes.

The GASB 33 Approach: Recognize Revenue When Earned

GASB Statement No. 33, Accounting and Financial Reporting for Nonexchange Transactions, governs how governmental utilities recognize CIAC. Under GASB 33, CIAC is classified as a voluntary nonexchange transaction — a contribution made voluntarily without a direct exchange of equal value.

The recognition rule under GASB 33 is straightforward: recognize revenue when all eligibility requirements have been met. For CIAC, this typically means when the utility has constructed — or committed to construct — the qualifying infrastructure. In practice, most utilities recognize CIAC revenue in the period the contribution is received and the related construction obligation is established.

Journal Entry 1 — Receive the CIAC Cash

Account	Description	Debit	Credit
Cash	Receipt of developer contribution	$150,000
CIAC Revenue	Nonexchange revenue — GASB 33		$150,000

Journal Entry 2 — Capitalize the Constructed Plant

Account	Description	Debit	Credit
Electric Plant in Service (Account 364/365)	Distribution line construction	$150,000
Cash / CWIP	Construction costs incurred		$150,000

Under this approach, the utility records $150,000 of revenue in the current period and $150,000 of plant that will be depreciated over its useful life — typically 30 to 40 years for distribution lines. The mismatch is clear: the revenue is front-loaded in one year, while the related depreciation expense is spread over decades. This inflates income in the year of contribution and understates it in subsequent years.

The GASB 62 Approach: Regulatory Liability Deferral

GASB Statement No. 62, Codification of Accounting and Financial Reporting Guidance Contained in Pre-November 30, 1989 FASB and AICPA Pronouncements, incorporates regulatory accounting concepts for governmental utilities subject to rate regulation. Under GASB 62, a utility can establish a regulatory liability for CIAC when rate regulation requires that the benefit of the contribution be passed back to ratepayers over time through reduced future rates or lower depreciation recovery.

The logic is straightforward: if regulators require that CIAC reduce the rate base or reduce future rate revenues, then immediately recognizing all $150,000 as revenue overstates current income relative to what ratepayers will actually fund. A regulatory liability defers the income recognition to match the period over which the contributed asset is depreciated — creating a clean match between the asset's cost recovery and the amortization of the related deferral.

Journal Entry 1 — Receive the CIAC and Establish the Regulatory Liability

Account	Description	Debit	Credit
Cash	Receipt of developer contribution	$150,000
Regulatory Liability — CIAC	Deferred CIAC under GASB 62		$150,000

Journal Entry 2 — Capitalize the Constructed Plant

Account	Description	Debit	Credit
Electric Plant in Service (Account 364/365)	Distribution line construction	$150,000
Cash / CWIP	Construction costs incurred		$150,000

Journal Entry 3 — Annual Amortization of the Regulatory Liability

Assuming a 30-year asset life, the regulatory liability is amortized at $5,000 per year ($150,000 ÷ 30 years), recognized as revenue as the ratepayer benefit is delivered:

Account	Description	Debit	Credit
Regulatory Liability — CIAC	Annual amortization	$5,000
CIAC Amortization Revenue	Revenue recognized ratably		$5,000

This entry repeats each year for 30 years, matching CIAC revenue recognition to the depreciation period of the contributed asset. The result is a clean offset: depreciation expense on the contributed plant is largely offset by the amortization of the regulatory liability each year, producing a near-neutral net income impact annually.

Which Approach Is Right for Your Utility?

The GASB 62 regulatory liability approach produces more accurate matching of revenues and expenses for rate-regulated utilities, and it better reflects the economic reality of how CIAC affects ratepayers over time. However, it requires that your utility meet the criteria for regulatory accounting under GASB 62 — specifically, that a regulator sets rates that are designed to recover costs, and that it is probable that those rates will allow recovery of costs and will not produce rates so high as to cause future customer losses.

Municipal utilities and cooperatives that set their own rates and are not subject to formal rate regulation may not qualify for GASB 62 regulatory accounting and would default to the GASB 33 immediate recognition approach. Utilities that do qualify should work with their auditors to document the regulatory basis for deferring CIAC as a regulatory liability.
