Lease Accounting (ASC 842)

What Is ASC 842?

ASC 842 is the FASB standard governing lease accounting under U.S. GAAP. It replaced ASC 840 and requires lessees to recognize a right-of-use asset and a lease liability for substantially all leases, rather than keeping operating leases off the balance sheet as the prior standard allowed.

Lessees still classify each lease as finance or operating, and the distinction drives the income statement: a finance lease produces front-loaded expense (amortization plus interest), while an operating lease produces a single straight-line lease cost. Both sit on the balance sheet. A policy election exempts short-term leases (12 months or less, no purchase option reasonably certain of exercise).

ASC 842 also addresses lessor accounting, which follows a separate model largely carried forward from ASC 840, and it requires disclosures covering the nature of the leasing arrangements, the significant judgments made, and the amounts recognized.
