ASC 842 Lease Accounting: Common Errors and SEC Comment Letters (2026 Guide)

ASC 842 has been fully effective for public companies since 2019, yet the SEC's Division of Corporation Finance keeps issuing comment letters on lease accounting disclosures. If your team is preparing a 10-K or 10-Q, or responding to an open comment, this guide maps the exact SEC comment language to the codification paragraph being cited, explains the underlying error, and tells you what to add to the footnote.

Key takeaway: The five recurring SEC comment clusters on ASC 842 all share one root cause: disclosures that track the standard's language without adding entity-specific content. Fix that, and you eliminate the majority of comment risk.

What ASC 842 Disclosures Does the SEC Most Commonly Comment On?

The SEC's highest-frequency ASC 842 comments fall into five clusters: discount rate methodology, boilerplate qualitative disclosures, incomplete quantitative tables, variable lease payment presentation, and build-to-suit or sale-leaseback accounting. A sixth area, transition period disclosures under ASU 2018-11, has also generated repeated comments for companies that adopted using the optional modified retrospective method.

Deloitte's Hindsight Is 2020 Heads Up, which reproduces actual SEC comment letter language verbatim, remains the most comprehensive public compilation of SEC staff comments on Topic 842. FASB's own Post-Implementation Review (PIR), with roundtable materials published September 12, 2025, confirms that discount rate determination and lease identification in complex arrangements are the top unresolved practitioner pain points, years after adoption.

The table below maps each comment cluster to the codification paragraph the SEC cites, the typical comment language, and the remediation action.

Discount Rate Disclosure: The Single Biggest SEC Comment Trigger

The SEC's most frequently issued ASC 842 comment targets the weighted-average discount rate disclosure, citing ASC 842-20-50-3(c)(3), when registrants report a rate without explaining how it was determined.

The SEC comment language documented by Deloitte takes two forms:

"We note your disclosure that your weighted average discount rate on operating leases is [X]%. Please tell us and revise to disclose how you determined the discount rate. See ASC 842-20-50-3(c)(3)."

And, for companies disclosing both finance and operating lease rates:

"We note from your disclosure that the weighted-average discount rate used for finance leases is [X]% and the weighted-average discount rate used for operating leases is [Y]%. Please provide us with additional details regarding how you determined or calculated the weighted-average discount rates for each class of your leases."

A third variant targets the implicit rate question directly:

"We note your disclosure that when available, you use the rate implicit in the lease to discount lease payments to present value; however most of your leases do not provide a readily determinable implicit rate. Please tell us if you have used the rate implicit in the lease for any of your lease payment calculations. If so, describe the circumstances and how you obtained the inputs to determine the rate implicit in the lease."

The underlying error in all three cases is the same: the footnote states a conclusion (the rate) without explaining the methodology. A disclosure that says "we used our incremental borrowing rate because the implicit rate was not readily determinable" is not enough. The SEC wants to know how the IBR was constructed.

What to add to your footnote:

• The collateralized borrowing rate used as the starting point
• How the rate was adjusted for lease term (short, medium, long)
• Whether the rate was determined at commencement date or using a portfolio approach
• The credit profile and currency inputs used
• Whether a third-party valuation was used

One additional precision point: your disclosure should state that the IBR was used because the implicit rate is not "readily determinable," not because the lease "does not provide" an implicit rate. The implicit rate is a calculated figure, not a stated one. That distinction has drawn SEC comments.

Boilerplate Qualitative Disclosures: What ASC 842-20-50-3 Actually Requires

ASC 842-20-50-3 requires disclosure of significant assumptions and judgments, including whether a contract contains a lease, how consideration is allocated between components, and how the discount rate was determined. The SEC comments when registrants copy the standard's language without providing entity-specific content.

The full qualitative disclosure requirement under ASC 842-20-50-3 covers:

• Significant assumptions and judgments: whether a contract contains a lease; allocation of consideration in a contract; discount rate
• Nature of leases: general description; basis and terms for variable lease payments; terms of extension and termination options; residual value guarantees; restrictions or covenants
• Leases not yet commenced: including the nature of any involvement with construction or design of the underlying asset

The last item is frequently missed. Companies with a significant pipeline of new leases or build-to-suit arrangements must disclose uncommenced leases, including construction involvement. This is a clean miss for real estate-intensive companies.

Practical expedient disclosures are also required and frequently incomplete. Two expedients generate the most SEC comment risk:

1. Short-term lease exemption (ASC 842-20-25-2): If elected, you must disclose the election and quantify the related cost recognized. Electing without quantifying draws comments.
2. Non-separation of lease and nonlease components: Per PwC's Viewpoint guidance, this election must be disclosed by class of underlying asset. Registrants that elect it without disclosing it have received SEC comments.

The Quantitative Disclosure Table: Every Line Item the SEC Checks

ASC 842-20-50 requires a specific set of quantitative disclosures. SEC comments have been issued for missing individual line items, particularly variable lease cost and supplemental noncash information.

The complete required set includes:

• Finance lease cost (amortization of ROU asset; interest on lease liability)
• Operating lease cost
• Variable lease cost
• Short-term lease cost
• Sublease income
• Net gain or loss from sale-leaseback transactions
• Cash paid for amounts included in measurement of lease liabilities (operating and financing)
• Supplemental noncash information (ROU assets obtained in exchange for new lease liabilities)
• Weighted-average remaining lease term (finance and operating)
• Weighted-average discount rate (finance and operating)
• Maturity analysis of lease liabilities (undiscounted cash flows by year, reconciled to the balance sheet carrying amount)

The maturity analysis reconciliation to the balance sheet is where many companies fall short. The undiscounted cash flows must tie to the present value of lease liabilities on the balance sheet, with the discount clearly shown. When the MD&A contractual obligations table presents operating lease obligations inconsistently with the ASC 842 footnote maturity analysis, the SEC notices and comments.

One terminology point worth flagging: Topic 842 does not characterize the periodic reduction of an operating lease ROU asset as "amortization." It is part of a "single lease cost." Using the word "amortization" in cash flow reconciliations has drawn comments. A cleaner description is "reduction in the carrying amount of ROU assets."

Variable Lease Payments: The Specificity the SEC Expects

The SEC expects variable lease payment disclosures to identify the specific basis on which variable payments are determined, with sensitivity analysis where the amounts are material.

The Deloitte Heads Up provides three model disclosures that illustrate the level of specificity the SEC considers adequate:

• CPI-linked payments: "A majority of leases are subject to annual changes in the consumer price index (CPI). While lease liabilities are not remeasured as a result of changes to the CPI, changes to the CPI are treated as variable lease payments and recognized in the period in which the obligation for those payments was incurred. A 100-basis-point increase in CPI would have resulted in $6.8 million in additional lease costs."
• Percentage-of-sales payments: "The company is obligated to pay the lessor 2 percent of its retail store's sales. Such amounts are not included in the measurement of the lease liability but will be recognized as variable lease expense when they are incurred."
• Output-based payments: "All of the payments made to lease the solar facility are variable. The company pays a stated rate per megawatt produced by the solar facility."

Variable lease cost is also broader than many teams realize. It includes not just percentage rent, but also CPI step-ups above the initial measurement, variable portions of common area maintenance charges, and property tax and insurance pass-throughs. Incomplete variable lease cost line items draw comments.

Build-to-Suit and Sale-Leaseback: Where the SEC Asks for Explanations

For build-to-suit and construction-phase arrangements, the SEC has issued comments asking registrants to explain their ASC 842 accounting, specifically citing ASC 842-40-55-3 through 55-5.

The exact comment language:

"We note that you have entered into lease agreements related to redevelopment projects. Please explain to us how you accounted for these projects and lease agreements under ASC 842."

And for a specific construction commitment:

"We note that you entered into a non-cancellable lease for an office building with an estimated construction cost of $[X] million. Please explain to us how you account for this project and lease agreement under ASC 842. See guidance in ASC 842-40-55-3 through 55-5."

The lessee-as-deemed-owner analysis under ASC 842-40 is the technical question the SEC is probing. If the lessee controls the underlying asset during construction, it is the accounting owner and must recognize a construction-in-progress asset and a corresponding financing obligation, not a lease. The disclosure must explain which conclusion was reached and why.

For sale-leaseback transactions, the SEC's focus is on whether the transfer of the asset qualifies as a sale under ASC 606 and whether the leaseback is properly classified. Net gain or loss from sale-leaseback transactions is a required line item in the quantitative disclosure table and must be presented separately.

Transition Period Disclosures: A Persistent Comment for ASU 2018-11 Adopters

Companies that adopted ASC 842 using the optional modified retrospective method under ASU 2018-11 must continue to provide ASC 840 disclosures for all comparative periods still reported under ASC 840. Failing to do so has generated SEC comments citing ASC 842-10-65-1(jj).

The SEC comment language:

"We note that you adopted ASC 842 using the optional transition method provided in ASU No. 2018-11. Please tell us how your disclosure complies with ASC 842-10-65-1(jj) with respect to all periods that continue to be in accordance with ASC 840."

This is a clean compliance miss, not a judgment call. If your comparative period financial statements were prepared under ASC 840, the ASC 840 disclosures must appear in those periods. The cumulative-effect adjustment recognized at adoption must also be clearly disclosed.

What FASB's Post-Implementation Review Found (September 2025)

FASB's PIR of Topic 842, with roundtable materials published September 12, 2025, evaluated 12 agenda requests and 12 unsolicited comment letters, and confirmed that lease identification in complex arrangements and discount rate determination remain the top unresolved implementation issues.

The PIR roundtable materials document that FASB has issued eight Accounting Standards Updates to clarify and amend Topic 842 since the original ASU 2016-02. The volume of clarifying updates is itself a signal: this standard is harder to apply than it looks, and the implementation challenges are not fully resolved.

The most recent significant amendment, ASU 2023-01 (Common Control Arrangements), addresses a specific pain point for private companies and not-for-profit entities. As FASB noted in the Basis for Conclusions: "Private company stakeholders observed that determining the enforceable terms and conditions of a common control arrangement to apply Topic 842 often is difficult and costly. Specifically, private company stakeholders stated that determining the enforceable terms and conditions of those arrangements could necessitate obtaining a formal legal opinion in certain cases."

ASU 2023-01 provides a practical expedient allowing eligible entities to use the written terms and conditions of the arrangement to determine whether a lease exists and how to classify it. The expedient is effective for fiscal years beginning after December 15, 2023 for public entities and December 15, 2024 for all other entities, with early adoption permitted. The ASU received 29 comment letters during the exposure draft period, reflecting the breadth of practitioner concern.

For public companies, the common control arrangement issue is less directly addressed by ASU 2023-01 (which scopes to private companies and NFPs), but the underlying complexity of identifying enforceable lease terms in related-party arrangements applies broadly. Public companies with intercompany lease arrangements should document the enforceable terms carefully and disclose the accounting basis.

FASB's PIR process signals that further amendments to ASC 842 remain possible. Teams should monitor the FASB standards update index for any new guidance before the next annual filing.

One Tool Most Finance Teams Underuse: EDGAR Comment Letter Search

The SEC's EDGAR full-text search system (EFTS) lets you search all public comment letters by keyword, giving you a real-time view of what the SEC is asking peer companies about their ASC 842 disclosures.

All SEC comment letters and company responses are posted to EDGAR typically 20 business days after the review is resolved, per the SEC's Division of Corporation Finance. You can search for terms like "ASC 842," "incremental borrowing rate," or "right-of-use" using EDGAR EFTS filtered to the UPLOAD form type (which captures comment letters) and a recent date range.

This approach lets you benchmark your lease footnote against companies in your industry that have already been through SEC review, identify the specific language that satisfied the staff, and spot gaps in your own disclosures before filing. Our EDGAR benchmarking guide walks through the full search methodology.

For teams managing an active comment letter, the SEC Comment Letter Response Best Practices playbook covers the full process from receipt to closure, including how to frame responses on accounting judgment questions.

FAQ

Which ASC 842 codification paragraph does the SEC cite most often in comment letters? ASC 842-20-50-3(c)(3), which requires disclosure of significant assumptions and judgments about the discount rate. The SEC cites it when registrants disclose a weighted-average discount rate without explaining how it was determined.

What is the correct reason to give for using the incremental borrowing rate? State that the IBR was used because the rate implicit in the lease is not "readily determinable," not because the lease "does not provide" an implicit rate. The implicit rate is a calculated figure; the distinction matters to the SEC.

Do we need to disclose leases that haven't started yet? Yes. ASC 842 requires disclosure of leases that have not yet commenced, including the nature of any involvement with the construction or design of the underlying asset. This is a frequently missed disclosure for companies with build-to-suit pipelines.

How do we find ASC 842 comment letters from peer companies? Use EDGAR's full-text search at EFTS, filter to form type UPLOAD (comment letters), and search for "ASC 842" or "incremental borrowing rate." All comment letters are public approximately 20 business days after the review closes.

Does ASU 2023-01 affect public companies? Directly, ASU 2023-01's practical expedient applies to private companies and not-for-profit entities. But public companies with intercompany or related-party lease arrangements face the same underlying challenge of documenting enforceable terms, and should review their common control arrangement disclosures regardless.

What happens if our MD&A contractual obligations table is inconsistent with the ASC 842 maturity analysis? The SEC has issued comments specifically on this inconsistency. The operating lease obligations in the MD&A table must align with the undiscounted cash flows in the footnote maturity analysis. Reconcile the two before filing.

For teams also managing disclosure of upcoming accounting changes, the SAB 74 disclosure guide covers what the SEC expects in your 2026 filings about any new ASUs not yet adopted, including any future Topic 842 amendments that may emerge from FASB's ongoing PIR process.
