Lease accounting can become complicated when a business manages multiple properties, equipment leases, vehicles, or other contracts. Under U.S. GAAP, ASC 842 provides the framework businesses use to identify, classify, measure, record, and disclose leases.

For businesses, ASC 842 compliance is not simply about recording a lease when a contract begins. Lease information must remain accurate throughout the lease term, including when payments change, contracts are modified, or renewal options are exercised.

This step-by-step guide explains how businesses can approach ASC 842 lease accounting with greater confidence.

What Is ASC 842?

ASC 842 is the Financial Accounting Standards Board (FASB) accounting standard that governs lease accounting under U.S. GAAP.

A major change introduced by ASC 842 was the requirement for lessees to recognize most leases on the balance sheet.

Generally, a lessee recognizes:

• Right-of-use (ROU) asset: The right to use an identified asset during the lease term.
• Lease liability: The obligation to make future lease payments.

The accounting treatment depends on whether the lease is classified as an operating lease or a finance lease.

Step 1: Identify All Leases

The first step toward ASC 842 compliance is finding every contract that may contain a lease.

Businesses should not only search for documents specifically titled "lease agreement." A lease may be included within a broader contract for services, equipment, transportation, technology, or other arrangements.

A contract generally contains a lease when it provides the customer with the right to control the use of an identified asset for a period of time in exchange for consideration.

To avoid missing leases, accounting teams should work with departments such as:

• Procurement
• Legal
• Facilities
• Operations
• IT
• Finance

A centralized contract review process can make lease identification more reliable.

Step 2: Gather Complete Lease Information

After identifying a lease, collect the information needed for accounting.

Important details may include:

• Lease commencement date
• Lease term
• Payment amounts
• Payment frequency
• Renewal options
• Termination options
• Purchase options
• Variable payments
• Lease incentives
• Initial direct costs
• Discount rate

Incomplete contract information can result in incorrect lease calculations.

Businesses should maintain supporting copies of agreements and amendments so accounting teams can verify the information used in their calculations.

Step 3: Determine Lease Classification

Under ASC 842, lessees generally classify leases as either finance leases or operating leases.

A finance lease is generally similar to a financed purchase because the arrangement may transfer substantially all the risks and benefits associated with ownership.

An operating lease does not generally have the same ownership-like characteristics.

The classification affects how lease expense is presented in the financial statements, so businesses should document their assessment and supporting conclusions.

Step 4: Determine the Lease Term

The lease term is an important part of ASC 842 measurement.

Businesses should consider the noncancelable period as well as applicable renewal and termination options when determining the lease term.

For example, if a company has an option to extend a property lease, the accounting team may need to assess whether exercising that option is reasonably certain based on the facts and circumstances.

Changes in expectations about renewal or termination options can also affect lease accounting.

Step 5: Calculate the Lease Liability

The next step is measuring the lease liability.

Generally, the lease liability is based on the present value of lease payments that are not yet paid.

The discount rate is therefore an important component of the calculation.

Depending on the applicable circumstances, a company may use the rate implicit in the lease when readily determinable or its incremental borrowing rate.

For companies with numerous leases, performing these calculations manually can create unnecessary administrative work and increase the possibility of errors.

Step 6: Calculate the Right-of-Use Asset

After calculating the lease liability, the business generally recognizes a corresponding ROU asset, subject to adjustments required by ASC 842.

The ROU asset represents the company's right to use the underlying asset during the lease term.

The initial measurement may need to consider items such as:

• Initial lease payments
• Lease incentives
• Initial direct costs
• Other applicable adjustments

Maintaining a detailed calculation schedule helps support the balance recorded in the financial statements.

Step 7: Record the Initial Journal Entry

Once the required calculations are complete, the accounting team can record the initial lease entry.

A simplified example for an operating lease may involve recognizing:

Debit: Right-of-use asset
Credit: Lease liability

The actual journal entry can vary depending on the terms of the arrangement and applicable accounting guidance.

Businesses should ensure that journal entries agree with the supporting lease schedule.

Step 8: Track Lease Payments and Ongoing Accounting

ASC 842 compliance continues after the initial recognition.

Accounting teams need to track lease payments and update the lease liability and ROU asset according to the applicable accounting model.

For finance leases, businesses generally recognize interest expense and amortization separately.

For operating leases, lease expense is generally recognized as a single lease expense over the lease term.

Regular reconciliation between lease schedules and the general ledger can help identify errors early.

Step 9: Monitor Lease Modifications

Lease agreements can change during their lifecycle.

A business might:

• Extend the lease
• Reduce leased space
• Add additional assets
• Change payment amounts
• Terminate part of an agreement
• Exercise a renewal option

These changes may require the lease to be reassessed or remeasured under ASC 842.

Businesses should establish a process that ensures accounting is informed promptly whenever a lease contract changes.

Step 10: Prepare Required Disclosures

ASC 842 also includes financial statement disclosure requirements.

Disclosures are intended to provide users with useful information about a company's leasing activities, including information about lease costs, maturity, and other relevant aspects of its lease arrangements.

Before financial statements are finalized, accounting teams should review their lease disclosures against their underlying lease records.

Common ASC 842 Compliance Mistakes

Businesses can reduce compliance problems by watching for common errors.

Missing Leases

Leases embedded in larger contracts may be overlooked.

Incorrect Lease Terms

Failing to consider renewal or termination options can affect measurement.

Outdated Lease Schedules

Payment changes and modifications can make existing schedules inaccurate.

Incorrect Discount Rates

An inappropriate discount rate can affect the lease liability calculation.

Poor Documentation

Even correct calculations can become difficult to defend when contracts, assumptions, and supporting schedules are not properly maintained.

ASC 842 Compliance Best Practices

A strong lease accounting process should be consistent and repeatable.

Businesses should:

1. Maintain a centralized lease database.
2. Review new contracts for embedded leases.
3. Document classification and measurement decisions.
4. Reconcile lease schedules with the general ledger.
5. Track amendments and modifications promptly.
6. Review renewal and termination options regularly.
7. Keep contracts and calculations together.
8. Use technology when managing a large lease portfolio.
9. Review financial statement disclosures before reporting.
10. Involve accounting professionals when complex arrangements require additional judgment.

Final Thoughts

ASC 842 compliance becomes much easier when businesses treat lease accounting as an ongoing process rather than a one-time calculation.

The key steps are straightforward: identify the lease, collect accurate data, determine classification and lease term, calculate the lease liability and ROU asset, record the accounting entries, monitor changes, and maintain appropriate disclosures.

For businesses with a large or complex lease portfolio, centralized lease management, regular reconciliations, and professional accounting support can help improve accuracy and reduce compliance risks.

A well-organized ASC 842 process not only supports compliance but also gives management a clearer picture of the company's financial obligations and long-term commitments.
