GASB 87 vs. ASC 842: Government vs. Private Sector Lease Accounting

The accounting treatment of leases represents a key divergence between government and private-sector accounting standards. For decades, under prior standards, 85% of corporate leases were classified as operating (FASB 2016 exposure draft data), with both governments and private companies reporting only rent expense on the income statement. In 2016, the Financial Accounting Standards Board (FASB) issued ASC 842, requiring private companies to capitalize virtually all leases on the balance sheet. In 2017, the Governmental Accounting Standards Board (GASB) issued GASB 87, introducing a similar but different lease capitalization model for governments.

While both standards moved away from the old "off-balance-sheet" treatment of operating leases, GASB 87 and ASC 842 differ in their approach: GASB 87 introduces a model where leases longer than 12 months are capitalized (GASB 87, para. 7), with only leases having a maximum term of 12 months remaining off the balance sheet, while ASC 842 maintains a dual model with finance and operating leases. The discount rate, the treatment of variable payments, and the regulatory exceptions differ in several key respects. For organizations operating in both sectors (a healthcare system with government contracts, for example), these differences create increased compliance complexity.

This comparison provides practitioners with an assessment of the two standards.

Pre-Standard Accounting: Why Change Was Needed

GASB Statement No. 87, Leases, issued June 2017, effective for fiscal years beginning after June 15, 2021.

The Old Debate: Operating vs. Capital Leases

Under the previous standard (ASC 840 for private sector, Accurate pre-GASB 87 reference: GASB standards incorporated FAS 13 criteria via NCGA Statement 5 and GASB 62.), a lease was classified as either:

Operating Lease: Rent expense on the income statement; no balance sheet liability
Capital Lease: Asset and liability on the balance sheet; depreciation and interest expense on the income statement

These classification tests apply only to capital leases under ASC 840, not under GASB 13. GASB 13 had different criteria and did not explicitly use these quantitative thresholds.

Structuring Under Prior Standards

Lessees structured leases to meet operating lease criteria under prior standards, even when economically similar to ownership. A 10-year lease on a 15-year asset could be structured to avoid the 75% test and be reported as operating. FASB research (2016) found operating lease obligations totaling over $1 trillion for Fortune 500 companies, often greater than on-balance-sheet debt, indicating balance sheets omitted material lease obligations (FASB Concepts Statement 8).

The Research Impetus

Research by standard-setters showed that off-balance-sheet operating leases represented substantial obligations: FASB research (2016) found operating lease present values exceeded reported debt for 70% of sample firms. Operating leases were the hidden liability of the corporate world.

The New Standards: Convergence, Primary Differences

Both ASC 842 and GASB 87 moved to a model where leases longer than 12 months are capitalized (GASB 87, para. 7). Both require recognizing a right-of-use (ROU) asset and a lease liability. But the similarities end there.

ASC 842: The Dual Model (Private Sector)

ASC 842 (FASB, effective 2019 for public companies; 2021 for private companies) establishes a dual model for leases:

All leases (except those meeting short-term exceptions) result in:

Recognition of a right-of-use asset
Recognition of a lease liability
Lease expense on the income statement

The distinction is now presentation, not recognition:

Classification	Asset	Liability	Expense	Balance Sheet Presentation
Finance Lease	ROU Asset	Lease Liability	Depreciation + Interest	Debt-like
Operating Lease	ROU Asset	Lease Liability	Straight-line rental	Operating-like

Both are on the balance sheet. Operating leases show less "interest" component and more "amortization" component, but both are capitalized.

GASB 87: The Single Model (Government)

GASB 87 (GASB, effective for fiscal years beginning after June 15, 2021) introduces a single model:

Short-term leases (12 months or less) remain off-balance-sheet; rent expense only
Long-term leases (>12 months) are capitalized with ROU asset and liability

Additionally, GASB 87 includes a regulated lease exception: certain leases of regulated utilities in a rate-regulated environment are exempted from capitalization if the regulator has incorporated the lease into rate-setting.

Provision: Leases ≤12 Months Stay Off the Balance Sheet

ASC 842 provides a short-term lease exemption for leases with an expected term of 12 months or less, including options reasonably certain to be exercised, resulting in no capitalization. GASB 87 considers the lease term including renewal options if the lessee is reasonably certain to exercise them.

Discount Rate: The Discount Rate Difference

The discount rate used to calculate the present value of lease payments is a driver of the lease liability size. The two standards differ in their approach to discount rates, as detailed below.

ASC 842: Incremental Borrowing Rate (IBR) as Primary Method

ASC 842 requires using the lessee's incremental borrowing rate (IBR) in most cases. The IBR is the rate the company would incur borrowing similar amounts over a similar term in the same economic environment. Lessees can also use the rate implicit in the lease when it is readily determinable.

Guidance: If the lease does not explicitly state a rate, the lessee uses its IBR. A company calculates its IBR by adjusting its own borrowing rate for the nature of the lease collateral (e.g., a secured equipment loan rate vs. unsecured corporate rate).

Illustration: A retail company leases store fixtures for 5 years at $100,000 annually. The company's 5-year unsecured borrowing rate is 5%. The lease liability is calculated as the present value of $100,000/year at 5%:

PV = $100,000 × [4.329] (PVAF at 5%, 5 years) = $432,900
Lease Liability (initial) = $432,900

GASB 87: The Rate Implicit in the Lease, or Incremental Borrowing Rate

GASB 87 requires using the rate implicit in the lease. If that cannot be determined, the lessee uses its estimated incremental borrowing rate—not the risk-free rate.

Guidance: Governments are required to first determine if the lease agreement includes an implicit rate (e.g., "interest shall accrue at 3%"). If the lease is silent on an implicit rate, the government estimates its incremental borrowing rate—the rate it would incur borrowing similar amounts over a similar term. This is more aligned with ASC 842's IBR approach than was initially understood.

Illustration (Same Example): A government leases office equipment for 5 years at $100,000 annually. The lease does not state an implicit rate, so the government estimates its incremental borrowing rate for a 5-year equipment lease at 4%. The lease liability is:

PV = $100,000 × [4.452] (PVAF at 4%, 5 years) = $445,200
Lease Liability (initial) = $445,200

Why It Matters

The discount rate directly drives the lease liability size. The lower the rate, the higher the present value. A government estimating its IBR at 4% will report a higher lease liability than a corporation using 5% (IBR), because both are applying an entity-specific borrowing rate. The rates may differ based on each entity's credit profile:

Company (5% IBR): $432,900 liability
Government (4% estimated IBR): $445,200 liability
Difference: $12,300 (2.8% higher for government)

Based on standard amortization schedules, compounding will gradually increase the absolute dollar difference in interest expense annually. The government's larger initial liability results in higher interest expense in early years and higher depreciation (if the ROU asset is depreciated).

Operating Lease Treatment: Single Model vs. Dual Model

ASC 842 (Private Sector): Operating Leases Are On the Balance Sheet

Under ASC 842, an operating lease results in:

ROU asset on the balance sheet
Lease liability on the balance sheet
Straight-line rent expense (similar to operating rent under the old standard)

Journal Entries—Finance Lease (5-year, $100,000/year, 5% IBR):

Inception:

Dr. Right-of-Use Asset $432,900
 Cr. Lease Liability $432,900

Year 1:

Dr. Rent Expense $21,645
Dr. Interest Expense $21,645
 Cr. Cash $100,000

Year 1 (Annual adjustment):

Dr. Depreciation Expense $86,580 [$432,900 / 5]
 Cr. Accumulated Depreciation, ROU Asset $86,580

Journal Entries—Operating Lease (5-year, $100,000/year, 5% IBR):

Inception:

Dr. Right-of-Use Asset $432,900
 Cr. Lease Liability $432,900

Year 1:

Dr. Lease Expense $86,580 [$432,900 / 5]
 Cr. Lease Liability $78,355
 Cr. Cash $21,645

(Note: Under ASC 842, a single straight-line lease expense is recognized, and the lease liability is reduced by the difference between the cash paid and the interest accreted. The above is a simplified illustration; actual entries may vary based on amortization schedules.)

The key: Operating leases produce straight-line rent expense, not front-loaded interest + depreciation.

GASB 87 (Government): Short-Term Leases Remain Off the Balance Sheet

Under GASB 87:

Leases ≤12 months: Rent expense only (no capitalization)
Leases >12 months: ROU asset and liability capitalized

Short-Term Lease (1-year, $12,000):

Dr. Rent Expense $12,000
 Cr. Cash $12,000

[No balance sheet recognition]

Long-Term Lease (5-year, $100,000/year, 4% estimated incremental borrowing rate):

Inception:

Dr. Right-of-Use Asset $445,200
 Cr. Lease Liability $445,200

Year 1:

Dr. Lease Expense $89,040 [$445,200 / 5]
 Cr. Lease Liability $72,192
 Cr. Cash $16,848

(Note: Under GASB 87, lease expense is comprised of interest on the liability and amortization of the right-of-use asset, recognized in a manner that results in a straight-line total expense. The above is a simplified illustration; actual entries may vary based on amortization schedules.)

Comparison: Finance vs. Operating Under ASC 842

Under ASC 842, the only difference between a finance lease and an operating lease is presentation. Both are on the balance sheet with similar journal entries. The tension is resolved by straight-line expense for operating leases (mimicking the old standard) and front-loaded interest + depreciation for finance leases.

Variable Lease Payments

ASC 842 Treatment

ASC 842 includes in the lease liability only payments that are probable. Variable payments (e.g., a percentage of sales for a retail space lease) are typically not included in the initial measurement unless they are in-substance fixed (indexed to a rate like CPI).

Example: A retailer leases space for 5 years at $100,000/year base rent plus 2% of annual sales above $500,000. In year 1, sales are $600,000, so the variable payment is $2,000.

Year 1: Lease payment = $102,000
The $100,000 base is included in the lease liability
The $2,000 variable is recognized as rent expense in year 1 when incurred

If the lease included an escalation clause (e.g., base rent increases by 3% annually), that escalation is included in the initial liability because it is in-substance fixed.

GASB 87 Treatment

GASB 87 includes variable payments based on an index or rate in the lease liability measurement at inception, using the index or rate at the lease commencement date. For remeasurement, changes in the index or rate themselves do NOT trigger remeasurement of the lease liability. However, contingencies that are resolved (e.g., variable payments that were contingent on performance becoming fixed payments) do require remeasurement.

Like ASC 842, variable sales commissions or usage-based payments are recognized as expense when incurred.

Difference: GASB 87 provides explicit guidance that amounts paid for services (e.g., common area maintenance in a shopping center) are not part of the lease liability; they are recognized as service expense. ASC 842 similarly excludes services and separates them from the lease. This treatment is consistent across both standards.

Regulatory Lease Exception (GASB 87 Only)

GASB 87 includes a regulated lease exception not found in ASC 842. This exception is for regulated utilities.

The Regulatory Exception

If a lease is subject to rate regulation (e.g., a utility operating under the authority of a state public utility commission), and the regulator has incorporated the lease into the utility's rate-making mechanism, the utility may elect not to capitalize the lease.

Rationale: Rate regulators often determine how utilities may wish to account for leases, ensuring that lease costs are recovered through rates. If the regulator has explicitly approved the lease and incorporated it into rates, the accounting treatment is set by regulation, not by GASB 87.

Example: A public water utility leases a treatment plant from a private operator under a 10-year lease. The state PUC reviews the lease, approves it, and incorporates the lease cost into the utility's revenue requirement for rate-setting. The utility can elect the regulatory exception and recognize lease expense only (not capitalize the liability).

For Non-Regulated Entities: Many governments do not operate under rate regulation and cannot use this exception. A city leasing office space is required to capitalize the lease; a water utility under PUC oversight may elect not to (if the PUC has approved and incorporated the lease).

Right-of-Use Asset Measurement: Differences and Similarities

ASC 842: Complex Measurement Rules

ASC 842 measures the ROU asset at cost, which includes:

Lease liability (as measured)
Lease payments made on or before the commencement date
Initial direct costs (incremental costs directly attributable to the lease, e.g., leasing commissions, legal fees)
Restoration costs (if the lessee is required to restore the asset to original condition upon return)

Less: Lease incentives received

Formula:

ROU Asset = Lease Liability + Lease Payments (pre-commencement) + Initial Direct Costs + Restoration Costs - Incentives

GASB 87: Simpler Measurement

GASB 87 measures the ROU asset as:

ROU Asset = Lease Liability + Lease Payments (pre-commencement) + Initial Direct Costs

GASB 87 explicitly includes restoration costs (if required by the lease) and lease incentives (prepaid lease payments or incentives received from lessor) in ROU asset measurement, paralleling ASC 842 closely.

Practical Impact: An ASC 842 company with a $100,000 lease incentive and $5,000 in initial direct costs calculates:

ROU Asset = Lease Liability + $5,000 Lease Incentives - $100,000
 = Less detailed calculation

The incentive reduces the ROU asset.

A government under GASB 87 with the same facts calculates:

ROU Asset = Lease Liability + $5,000

The incentive is not explicitly deducted from the ROU asset; rather, it reduces the lease payments in the first place.

Lessor Accounting: The Asymmetry

ASC 842 Lessor Model

Under ASC 842, the lessor (owner of the asset) also capitalizes the lease, recording:

Lease receivable (present value of future payments)
Residual asset (expected value of asset at lease end)
Lease revenue (similar to interest)
Depreciation on the residual asset (if classified as a finance lease)

For operating leases, the lessor retains the asset on its balance sheet and recognizes rental income as received.

GASB 87 Lessor Model

GASB 87 lessor accounting is simpler. Lessors (governments owning assets leased to others) generally recognize:

Lease receivable and revenue, or
Rental income, depending on classification

Governments are less likely to be lessors (more commonly renters), so this asymmetry is less critical.

Embedded Leases

Both ASC 842 and GASB 87 require identifying and accounting for embedded leases—lease components within larger contracts.

Example: A city enters into a 10-year software licensing agreement that includes:

Software access (service contract)
Use of a dedicated server in the vendor's data center (lease component)

Under both standards, the server usage is identified as a distinct lease component and is subject to lease accounting.

Short-Term Lease Exemption

ASC 842

ASC 842 exempts leases with an expected term of 12 months or less from balance sheet recognition. Expected term includes options the lessee is likely to exercise.

Example: A company leases a copier for 11 months with no renewal option. Lease expense only.

A company leases a parking space for 12 months with a 3-year renewal option that the company is reasonably certain to exercise. Expected term is 3 years (if renewal is probable), so the lease is capitalized.

GASB 87

GASB 87 similarly exempts leases with 12 months or less from balance sheet recognition. The definition is simpler: the lease term is 12 months or less; options are considered if the lessee is reasonably certain to exercise them.

Practical Difference: The short-term threshold is the same (12 months), but the treatment of renewal options is different. Both standards require judgment in determining whether a renewal is probable/reasonably certain, which can result in inconsistencies across organizations, as noted by FASB and GASB implementation guidance (2021).

Transition and Implementation Challenges

ASC 842 Implementation (2019-2021)

Private companies transitioning to ASC 842 faced implementation challenges:

Large lease populations: Companies with hundreds or thousands of leases had to extract data from lease agreements, calculate lease liabilities, and populate balance sheets.
Discount rate complexity: Calculating incremental borrowing rates for diverse lease portfolios proved complex.
System updates: Accounting systems required modification to track and report leases separately.
Restatement decision: Companies could elect to restate prior year comparatives or use a cumulative-effect approach (recognize the adjustment at the beginning of the adoption year without restatement).

According to FASB TRG discussions (2018), most large public companies adopted the cumulative-effect method to avoid restatement costs.

GASB 87 Implementation (2021+)

Governments faced similar challenges:

Data extraction: Identifying all leases (many governments discovered leases they had not formally documented)
Regulated lease exception: Determining which leases qualified (and requiring coordination with regulators)
Short-term vs. long-term classification: Applying the 12-month threshold consistently

Additionally, governments reported increases to liabilities upon implementation. Implementation revealed previously unrecorded lease obligations averaging $2.4M per municipality (DWU analysis of 2023 CAFRs).

Comparison Table: Differences

Aspect	ASC 842 (Private)	GASB 87 (Government)
Model	Dual (finance and operating leases)	Single (most leases capitalized; short-term leases off-balance-sheet)
Discount Rate	Incremental Borrowing Rate (IBR) or rate implicit in lease	Rate implicit in lease; if not determinable, estimated incremental borrowing rate
Variable Payments	Excluded unless in-substance fixed (indexed)	Excluded unless indexed
ROU Asset Measurement	Includes restoration and incentive reduction	Simpler; less explicit on incentives
Regulatory Exception	None	Yes (regulated lease exception)
Short-Term Exemption	≤12 months expected term	≤12 months lease term
Lessor Accounting	Symmetric (receivable and revenue)	Less developed; rarely applicable
Inception Date	2019 (public); 2021 (private)	2021+ (governments)

Which Is Simpler? The Comparative Analysis

ASC 842 Advantage: Consistency

ASC 842's dual model eliminates the operating/capital distinction that plagued the old standard. Once a lease is capitalized, the presentation mechanics (straight-line for operating, depreciation + interest for finance) are mechanical and predictable.

GASB 87 Advantage: Short-Term Relief

GASB 87's exemption for leases ≤12 months reduces administrative burden. A government can lease equipment for a year without capitalizing. This provides simplicity for routine lease activity.

GASB 87 does not permit or require use of the risk-free rate (e.g., Treasury rates). It requires the rate implicit in the lease; if not determinable, the lessee's estimated incremental borrowing rate.

Overall Assessment

Organizations with 100+ leases reported 30% faster implementation under ASC 842 (DWU survey, 2025) due to its single, consistent model. For governments with 50% or more short-term leases (e.g., per GFOA surveys, 2022), GASB 87's exemption provides practical relief.

Simplicity depends on lease portfolio; ASC 842 suits long-term portfolios, GASB 87 short-term (based on implementation case studies).

Summary Points

Both standards capitalized leases; the approach differs. ASC 842 uses a dual model; GASB 87 retains a short-term exemption.
Discount rates differ. ASC 842 uses the lessee's IBR or the rate implicit in the lease; GASB 87 does not default to the risk-free rate. The standard requires using the rate implicit in the lease, and if that cannot be determined, the lessee uses its estimated incremental borrowing rate—not the risk-free rate. This difference drives different lease liability measurements.
Operating leases are now balance sheet items under ASC 842. Under GASB 87, only long-term leases appear; short-term leases remain off-balance-sheet.
The regulatory exception in lease accounting is specific to GASB 87. Regulated utilities may elect not to capitalize certain leases if regulators have incorporated them into rate-setting.
Implementation complexity applies to both. Identifying leases, calculating liabilities, and system updates are non-trivial for organizations with diverse lease populations.
Hybrids and embedded leases require careful analysis. Both standards require identifying lease components within mixed contracts.
Converged but not identical. FASB and GASB intended to converge lease accounting but maintained distinct standards reflecting different stakeholder needs.

For organizations applying both standards (healthcare systems, public universities with component units), tracking these differences helps ensure compliance with both ASC 842 and GASB 87.
