Theory and Practice
If a lessee is required, for example, to restore a rented property to its original condition (e.g., remove leasehold improvements and repair any damage) or to decommission equipment at the end of a lease, there is a present obligation that arises from the lease contract or law. In many cases, lease restoration obligations are a type of Asset Retirement Obligation (ARO). If the lease includes, for example, removal of a leased asset (such as returning an aircraft in a specified condition or dismantling equipment), or environmental remediation, that obligation is accounted for as above.
IFRS
IFRS 16 explicitly addresses these costs. At lease commencement, the lessee must estimate any such dismantling or site restoration costs and recognize a provision under IAS 37 for the present value of those costs, while adding the same amount to the ROU asset (IASB, 2016; IASB, 1998). This mirrors the treatment of asset retirement obligations for owned assets under IAS 16. The provision (liability) is then accounted for under IAS 37: it is updated for the passage of time (unwinding of discount as interest expense) and revised for changes in estimate, while the ROU asset is depreciated over the lease term and adjusted if estimates change (IASB, 1998). For instance, if a lessee is obligated to remove leasehold improvements and repaint a facility at lease-end, estimated to cost £50,000 in 10 years, the lessee might record a £50,000 provision discounted to present value (say £30,000 at a 5% rate) and increase the ROU asset by £30,000 at commencement. Over 10 years, the provision is unwound to £50,000 (interest expense recognized), and the £30,000 added to the ROU asset is depreciated over 10 years (part of lease depreciation). Adjustments: If the cost estimate changes – e.g., partway through the lease the expected restoration cost increases – the lessee revises the provision and adjusts the ROU asset accordingly (IFRS Interpretations Committee, 2004). If the ROU asset is reduced to zero (fully depreciated or impaired) and the provision still increases, any excess would be recognized as a loss immediately. This follows IFRIC 1 guidance on changes in decommissioning liabilities (IFRIC 1 deals with asset retirement obligations, which is analogous to lease restoration obligations) (IFRS Interpretations Committee, 2004). At lease end, if actual restoration costs differ from the provision, any difference is recognized in profit or loss (e.g., if the lessee spent less than expected, the remaining provision is released to income).
US GAAP
Similarly, if a lease creates a legal obligation to restore or remove an asset, the lessee accounts for it as an Asset Retirement Obligation (ARO) under ASC 410 (GASB, 2024). This requires recognizing a liability at lease commencement for the present value of the future obligation and adding that amount to the carrying amount of the asset (in this case, the ROU asset) (FASB, 2016b). Subsequent accounting follows ASC 410’s ARO model: the liability is accreted (interest expense) over time, and the asset is depreciated. Changes in estimated cost or timing result in remeasuring the ARO, with corresponding adjustments to the ROU asset (FASB, 2024abc). Thus, if the earlier example occurred under US GAAP, the lessee at commencement would record (approximately) a $30,000 ARO liability and increase the ROU asset by $30,000. Over time, interest expense would accrue such that the liability reaches $50,000 by the end, and $30,000 would be included in the ROU asset amortization. If the estimate changes to $60,000 mid-way, the lessee would increase the ARO liability (with a hit to the ROU asset, unless the asset is fully depreciated, in which case any excess would be taken as a loss). One difference in guidance: IFRS includes constructive obligations (e.g., expectations set by industry practice) in the scope of provisions, whereas US GAAP’s ARO guidance only addresses legal obligations. In lease contexts, however, most end-of-lease restoration duties are legally enforceable, so this usually doesn’t create a difference. In both IFRS and GAAP, these costs can be significant (especially in real estate, telecom, and extractive industries), so companies must budget and plan for these cash outflows and ensure they are recognized properly.
UK GAAP
FRS 102 has long required recognition of provisions for lease restoration costs (under its Section 21, equivalent to IAS 37). Under old FRS 102, for an operating lease, a dilapidation provision would be recognized with an immediate lease expense (or spread over the lease term, e.g., by accruing a portion of the cost each period). With the new IFRS 16-aligned model, FRS 102 requires recognizing a provision and including the cost in the ROU asset, the same as IFRS 16 (FRC, 2022). Thus, the timing of expense recognition might actually be similar: previously, one could straight-line an expected dilapidation cost over the lease; now the cost is front-loaded slightly (interest accretion) and split between depreciation and interest, but the overall impact is comparable. UK companies, however, should note the balance sheet impact: under old UK GAAP such obligations were often disclosed or accrued near the lease end, whereas now the full discounted liability appears on Day 1 with a matching asset.
