IFRS 16 Leases Explained: The Single Lessee Model and Its Impact

IFRS 16 was one of the most disruptive accounting changes in a generation. By putting nearly every lease on the balance sheet, it transformed how lease-heavy businesses — retailers, airlines, logistics firms, energy groups — report their financial position. This guide explains the single lessee model, the measurement mechanics, the exemptions, and the wide-ranging effects on financial metrics.

What is the single lessee accounting model?

Under IFRS 16, a lessee recognises a right-of-use asset representing its right to use the leased item and a lease liability representing its obligation to make lease payments. This single model replaced the previous approach, where operating leases sat off-balance-sheet as a simple rental expense and only finance leases were capitalised. Now, with limited exceptions, every lease appears on the balance sheet.

The income statement also changes. Instead of a single straight-line rental expense, the lessee recognises depreciation on the right-of-use asset and interest on the lease liability. Because interest is higher in the early years, total expense is front-loaded over the lease term, even though cash payments may be level. This reshapes reported profit profiles for lease-intensive businesses.

How do you measure the lease liability and right-of-use asset?

The lease liability is measured at the present value of the lease payments not yet paid, discounted at the rate implicit in the lease or, if that cannot be determined, the lessee’s incremental borrowing rate. Lease payments include fixed payments, variable payments tied to an index or rate, residual value guarantees, and amounts expected under purchase or extension options that are reasonably certain to be exercised.

The right-of-use asset starts at the amount of the lease liability plus any initial direct costs, prepaid lease payments, and estimated restoration costs, less any lease incentives received. It is then depreciated, usually straight-line, over the shorter of the lease term and the asset’s useful life. Choosing the discount rate is one of the most judgmental and impactful inputs, since it determines both the liability and the asset.

What leases are exempt from capitalisation?

IFRS 16 provides two practical exemptions that keep some leases off the balance sheet. Short-term leases — those with a term of twelve months or less and no purchase option — can be expensed on a straight-line basis. Leases of low-value assets, such as laptops, small office equipment, or furniture, can likewise be expensed regardless of materiality in aggregate.

These exemptions reduce the compliance burden for high-volume, low-significance leases. But they must be applied carefully: the low-value assessment is based on the value of the asset when new, not the lease payments, and the short-term exemption is lost if a lease is reasonably certain to be extended beyond twelve months. Misapplying them can leave material leases incorrectly off the balance sheet.

How does IFRS 16 affect financial ratios and covenants?

Capitalising leases inflates both assets and liabilities, which changes nearly every balance-sheet ratio. Gearing and leverage rise as lease liabilities join debt; asset turnover falls as the asset base grows. On the income statement, EBITDA increases because rental expense is replaced by depreciation and interest that sit below the EBITDA line — a change that significantly affects any metric or multiple based on EBITDA.

These shifts can have real consequences for loan covenants written on pre-IFRS 16 definitions. A covenant measuring net debt to EBITDA, for example, moves in offsetting directions as both numerator and denominator change. Companies often had to renegotiate covenants or agree frozen-GAAP definitions with lenders to avoid technical breaches on transition, a coordination challenge explored across our IFRS hub.

How do lease modifications and remeasurements work?

Leases rarely stay static. When terms change — a rent revision, a change in term, a partial termination — IFRS 16 requires the lessee to reassess and remeasure. A modification that grants additional right of use at a commensurate price is treated as a separate lease; otherwise the liability is remeasured using a revised discount rate and the right-of-use asset is adjusted. Reassessments also arise when index-linked payments reset or when the likelihood of exercising an option changes.

This makes IFRS 16 an ongoing computational exercise, not a one-time capitalisation. Each remeasurement event recalculates the liability and adjusts the asset, and high-volume lease portfolios need systems to handle this automatically. The frequency of remeasurement is one reason a robust lease register and supporting software are essential rather than optional.

How should companies approach IFRS 16 transition and systems?

The transition to IFRS 16 was a substantial project for most lease-heavy businesses, and the lessons remain relevant whenever a group acquires a new entity or expands its lease portfolio. The standard offered two transition approaches — full retrospective and a modified retrospective method — and the choice affected comparatives, opening equity, and the effort involved. Whichever was chosen, the foundational task was the same: assembling a complete, accurate inventory of every lease, with terms, payments, options, and discount rates.

Systems are central to making IFRS 16 sustainable. A spreadsheet may suffice for a handful of leases, but any sizeable portfolio needs dedicated lease accounting software that computes the liability and right-of-use asset, handles remeasurements and modifications, and generates the maturity-analysis and movement disclosures. Companies that under-invested in systems found themselves rebuilding lease calculations manually each period, which is slow, error-prone, and difficult to audit. Treating lease data infrastructure as core, not peripheral, is the practical key to ongoing compliance.

How does IFRS 16 affect cash flow statement presentation?

IFRS 16 changes not just the balance sheet and income statement but also the cash flow statement. Under the old operating-lease model, lease payments appeared entirely within operating cash flows. Under IFRS 16, the repayment of the lease liability principal is presented within financing activities, and only the interest portion (and payments for short-term and low-value leases) typically remains in operating activities. The result is a reported improvement in operating cash flow.

This reclassification flatters operating cash flow metrics without any change in the actual cash leaving the business, much as the EBITDA effect flatters earnings. Analysts comparing pre- and post-IFRS 16 cash flows, or comparing IFRS 16 reporters with US GAAP operating-lease reporters, must adjust for this presentation difference. Understanding where lease cash flows sit is essential for any free cash flow or debt-service analysis, a theme that recurs across our IFRS hub.

How does lessor accounting work under IFRS 16?

While IFRS 16 transformed lessee accounting, it left lessor accounting largely intact, retaining the distinction between finance leases and operating leases. A lessor classifies a lease as a finance lease if it transfers substantially all the risks and rewards of ownership, and as an operating lease otherwise. For a finance lease, the lessor derecognises the underlying asset and recognises a receivable; for an operating lease, the asset stays on the lessor’s balance sheet and rental income is recognised over the term.

This asymmetry — lessees capitalising almost everything while lessors keep the old split — creates a structural mismatch in the accounting of the two parties to the same contract. For groups that both lease assets in and lease assets out, or that have intragroup leasing arrangements, understanding both sides is essential. Sale-and-leaseback transactions are a further area where lessor and lessee accounting interact in ways that require careful analysis under the standard.

What judgments most affect the lease liability?

Several judgments drive the size of the lease liability and therefore the right-of-use asset. The lease term is critical: it includes the non-cancellable period plus any extension options the lessee is reasonably certain to exercise and termination options it is reasonably certain not to exercise. Assessing reasonable certainty involves weighing economic incentives, leasehold improvements, and business plans, and it must be reassessed when significant events change the picture.

The discount rate is the other major judgment, as a higher rate produces a smaller liability and a lower rate a larger one. Variable lease payments, residual value guarantees, and purchase options also feed the measurement. Because these judgments compound across a large portfolio, small, consistent biases can materially misstate lease balances. Documenting the basis for each judgment, by asset class and entity, is what makes the numbers defensible, in keeping with the discipline emphasised across our IFRS hub.

What is the lasting strategic impact of IFRS 16?

Beyond the accounting mechanics, IFRS 16 changed how businesses think about the lease-versus-buy decision and about off-balance-sheet financing generally. By eliminating the ability to keep operating leases off the balance sheet, it removed a long-standing incentive to structure arrangements as leases purely for cosmetic balance-sheet reasons. Decisions about leasing now rest more on genuine economic and operational merits than on accounting presentation, which is a healthier basis for capital allocation.

The standard also gave investors a more complete view of a company’s commitments, since lease obligations that were once buried in the notes now sit on the balance sheet alongside debt. For lease-heavy sectors, this improved comparability between companies that lease and those that buy. The enduring lesson is that accounting transparency reshapes behaviour, a theme that recurs across the standards in our IFRS hub.
