Theory and Practice
When a lessee (head lessee) re-leases an underlying asset to a third party, it becomes an intermediate lessor with two roles: lessee to the original lessor, and lessor to the sublessee. The intermediate lessor must account for the head lease and sublease separately.
IFRS 16 classifies subleases as either finance or operating based on the right-of-use asset, while ASC 842 applies full lessor accounting—sales-type, direct financing, or operating—based on the underlying asset, leading to more granular outcomes under US GAAP. UK GAAP (FRS 102, effective 2026) follows IFRS 16.
Sublease classification
Sublease classification differs fundamentally between IFRS 16 and ASC 842, primarily due to the asset basis used for classification.
Under IFRS 16, the sublease is classified by reference to the right‑of‑use (ROU) asset arising from the head lease, not the underlying physical asset. This means the intermediate lessor assesses whether the sublease transfers substantially all of the remaining economic benefits of the ROU asset. In practice, if the sublease term covers most of the remaining head lease term, the sublease will typically be classified as a finance sublease (IASB, 2016).
By contrast, under ASC 842, sublease classification is determined by reference to the underlying asset, consistent with the general lessor model. The intermediate lessor applies the standard lease classification criteria (sales‑type, direct financing, or operating) based on the total economic life and fair value of the underlying asset, not the ROU asset (FASB, 2016b).
This distinction can lead to different outcomes for the same arrangement. For example, assume a company enters into a ten‑year head lease and, after two years, subleases the asset for the remaining eight years:
Under IFRS 16, the assessment is based on the ROU asset with an eight‑year remaining life. An eight‑year sublease term represents substantially all of that remaining life and would generally result in a finance sublease.
Under ASC 842, the assessment is based on the underlying asset’s total economic life. If that life were, for example, 30 years, an eight‑year sublease represents only a portion of the asset’s economic life. On that basis, the arrangement may fail the finance lease criteria and could be classified as an operating sublease.
Accordingly, IFRS 16 tends to result in more subleases being classified as finance, whereas ASC 842 more frequently results in operating classification for the same fact pattern (KPMG, 2021).
Finance sublease (IFRS 16) vs Sales-type / Direct financing sublease (ASC 842)
Under IFRS 16, a finance sublease results in the intermediate lessor:
Derecognizing the ROU asset (or the portion subject to the sublease)
Recognizing a net investment in the sublease
Recording any difference between the carrying amount of the ROU asset and the net investment as a gain or loss (typically limited in practice)
Recognizing interest income over time on the net investment
Under ASC 842, a sublease that meets finance-type criteria is further classified as either:
Sales-type sublease (if a selling profit or loss arises), or
Direct financing sublease (if no selling profit arises)
In both cases:
The intermediate lessor recognizes a net investment in the sublease
The underlying accounting model is similar to IFRS finance subleases, but
ASC 842 introduces an additional distinction regarding whether day‑one profit is recognized (sales-type) or deferred (direct financing)
Operating sublease (IFRS 16 vs ASC 842)
If the sublease is classified as operating, the accounting is broadly similar under both frameworks, though it arises more frequently under ASC 842 due to the different classification basis.
In an operating sublease, the intermediate lessor:
Retains the ROU asset on the balance sheet
Continues to depreciate the ROU asset
Recognizes sublease income on a straight-line basis over the sublease term
Head lease continuation
Regardless of sublease classification, the intermediate lessor continues to account for the head lease. There is no derecognition of the head lease liability. If the sublease is for a major part of the asset, the intermediate lessor might consider whether the head lease ROU asset is impaired (since its value is to come from the sublease cash flows). IFRS specifically notes that if a head lease was short-term or low-value (and so no ROU asset was recognized by the head lessee), then any sublease is automatically classified as operating by the intermediate lessor (a situation not common, because if no ROU asset is recognized, it means the head lease was short-term or low-value, and such leases are rarely subleased) (IASB, 2016). In sum, sublease accounting can be complex: IFRS and US GAAP may lead to different classification and measurement, so companies with significant subleasing activities must maintain careful records for each layer of the lease.
