Why IFRS 16 Matters for Scaling Businesses
IFRS 16, which became mandatory for annual periods beginning on or after 1 January 2019, fundamentally changed how lessees account for leases. Under the previous standard (IAS 17), a lessee could classify a lease as an operating lease and keep it entirely off the balance sheet, recognising only a straight-line rental charge through the income statement. IFRS 16 swept most of that away.
The practical significance for a scaling fintech or technology business is considerable. These businesses routinely lease office space (often long-term in central London locations), data centre co-location space, and equipment ranging from servers to coffee machines. Under IAS 17, none of this appeared on the balance sheet. Under IFRS 16, all leases with a term greater than 12 months and an underlying asset value above approximately £5,000 must be recognised on the balance sheet.
The scale of the adjustment is often a genuine surprise. A fintech with a five-year office lease at £200,000 per annum will recognise a lease liability of roughly £870,000 at commencement (the present value of five years of payments discounted at an appropriate rate). That is a material balance sheet item that simply did not exist under the old rules.
The Two Practical Exemptions
IFRS 16 provides two exemptions from recognition that are genuinely useful for scaling businesses and worth understanding in full before modelling your lease portfolio.
The short-term lease exemption applies to leases with a lease term of 12 months or less at the commencement date. If you take this exemption, the lease payments are recognised as an expense on a straight-line basis over the lease term, exactly as under IAS 17. This is particularly valuable for month-to-month flexible office arrangements or short-term equipment rentals. Note: the exemption must be elected by class of underlying asset, so you cannot cherry-pick lease by lease.
The low-value asset exemption applies to leases of underlying assets with a low value when new, regardless of the size of the lessee. The IASB indicated that assets with a value of approximately USD 5,000 (roughly £4,000 to £5,000) or below when new qualify. This covers individual pieces of office equipment, laptops, tablets, and similar items. Fleet leases and subleases of high-value assets do not qualify, even if the individual payment is small.
These exemptions are both available and both entirely optional. Many scaling businesses take them to reduce the administrative burden of lease accounting. The trade-off is that the associated costs remain above the EBITDA line, which is important if you are optimising reported EBITDA.
The Mechanics: Calculating ROU Asset and Lease Liability
At the commencement date of a lease, the lessee recognises both a right-of-use asset and a lease liability. The calculation mechanics are as follows.
Step 1: Determine the Lease Term
The lease term under IFRS 16 is the non-cancellable period plus any optional extension periods that the lessee is reasonably certain to exercise, plus any optional termination periods that the lessee is reasonably certain not to exercise. This is a matter of judgement and can significantly affect the initial measurement. A five-year lease with a five-year extension option that is reasonably certain to be exercised is a ten-year lease under IFRS 16.
Step 2: Determine the Discount Rate
The lease liability is discounted at the interest rate implicit in the lease, if that rate can be readily determined. In practice, for most property and equipment leases, the implicit rate is not readily determinable. In that case, the lessee uses its incremental borrowing rate (IBR): the rate of interest the lessee would have to pay to borrow over a similar term, with a similar security, the funds necessary to obtain an asset of a similar value to the ROU asset.
For a scaling fintech, the IBR typically reflects the company's credit quality and may be significantly higher than a large corporate's IBR. A Series B fintech with limited credit history might use an IBR of 6% to 8%, versus 3% to 4% for a FTSE 100 company. The IBR has a direct impact on both the initial lease liability measurement and the subsequent interest charge profile. Getting the IBR right, and documenting the basis, is an important early step.
Step 3: Initial Measurement of the Lease Liability
The lease liability is measured at the present value of the lease payments not yet paid at the commencement date. Lease payments include fixed payments (net of any lease incentives receivable), variable lease payments that depend on an index or rate, amounts expected to be payable under residual value guarantees, and exercise prices of purchase options if reasonably certain to exercise.
Step 4: Initial Measurement of the ROU Asset
The ROU asset equals the initial lease liability, plus any lease payments made at or before the commencement date, plus any initial direct costs incurred by the lessee, less any lease incentives received. In many property leases, the landlord provides a rent-free period or a fit-out contribution. These are lease incentives and reduce the ROU asset.
Annual rent: £200,000 per annum, payable monthly in arrears
Lease term: 5 years (60 months), no extension option
Incremental borrowing rate: 6% per annum (0.487% per month)
Lease incentive received: £30,000 rent-free at commencement
Initial lease liability = PV of 60 monthly payments of £16,667 at 0.487%/month
= £16,667 × [(1 - (1.00487)^-60) / 0.00487] = approximately £860,000
Initial ROU asset = £860,000 lease liability - £30,000 lease incentive = £830,000
Subsequent Measurement: Asset Depreciation and Liability Unwinding
After initial recognition, the ROU asset and lease liability follow different accounting paths, and this divergence is one of the most important things to understand about IFRS 16.
The ROU asset is depreciated on a straight-line basis over the shorter of the lease term and the asset's useful economic life. In the worked example above, the £830,000 ROU asset is depreciated at £166,000 per annum (£830,000 divided by five years). This depreciation charge appears in operating expenses, typically under depreciation within EBITDA, depending on your P&L presentation.
The lease liability unwinds using the effective interest method. Each period, an interest charge accrues on the outstanding balance, and the cash payment reduces the principal. Because the liability starts high, the interest charge is highest in the early periods and declines over the lease term as the principal reduces. This is the opposite of what happens with a straight-line operating lease charge, and it is the source of the well-known front-loading effect.
The total economic cost over the lease term is the same under both standards. The difference is purely one of timing and presentation. The front-loading effect means that P&L charges are higher in early years, which can matter significantly when reporting metrics during a fundraising process.
The Metric Impact: EBITDA, Net Debt and Operating Cash Flow
The most commercially important consequence of IFRS 16 is its effect on reported financial metrics. Understanding this is essential when presenting accounts to investors or managing debt covenants.
EBITDA improves under IFRS 16. Under IAS 17, operating lease payments were included above the EBITDA line as a property or rental cost. Under IFRS 16, that cost is replaced by depreciation of the ROU asset (which sits below EBITDA in the D&A line) and interest on the lease liability (which sits below EBITDA in finance costs). The result is that EBITDA is higher under IFRS 16 than it would have been under IAS 17, by approximately the value of the lease payments that have moved below the line. For a business with £1m per annum of leases, this could improve reported EBITDA by that full £1m.
Operating cash flow improves. Under IAS 17, the full lease payment appeared as a cash outflow within operating activities. Under IFRS 16, the lease payment is split: the interest portion remains in operating activities, but the principal repayment portion moves to financing activities. This improves reported operating cash flow, which is a meaningful metric for investor presentations and covenant calculations.
Net debt increases by the lease liability. The lease liability is financial debt. Many leverage ratios and debt covenants include lease liabilities in their definition of net debt. Before IFRS 16, your balance sheet might have shown net cash of £2m. After IFRS 16, with £860,000 of lease liability recognised, net debt could be negative even if your bank balance is positive. This must be modelled carefully, particularly if you have banking covenants or are in discussions with lenders.
"IFRS 16 is one of the few accounting standards that simultaneously improves EBITDA, improves operating cash flow, and increases net debt. All three effects flow from the same set of leases. Any investor or lender who does not understand this is working with the wrong model."
Common Lease Types for Fintechs and How They Are Treated
The practical application of IFRS 16 varies by lease type. Understanding the common lease structures in the fintech sector helps finance teams identify and correctly account for all in-scope arrangements.
Managing Lease Modifications, Extensions and Terminations
The ongoing accounting for leases is where many finance teams struggle. Once a lease is on the balance sheet, any change to its terms requires a formal reassessment and often a remeasurement of both the ROU asset and the lease liability.
A lease modification occurs when the scope or consideration of a lease changes in a way that was not part of the original terms. Adding extra space to an office lease is a modification. Depending on whether the modification grants an additional right of use (a new lease component), it is either accounted for as a separate lease or as a modification of the existing lease, with the liability remeasured at the revised payments discounted at a revised incremental borrowing rate as of the modification date.
A lease extension that falls within the scope of the original reasonably-certain assessment does not require remeasurement. However, if the lessee reassesses and concludes that it is now reasonably certain to exercise an extension option it had previously not included, the lease liability and ROU asset are remeasured immediately, using the revised lease term and the lessee's current IBR.
A lease termination requires derecognition of both the ROU asset and the remaining lease liability. Any difference is recognised in profit or loss as a gain or loss on termination. If a lease termination penalty is payable, that must be included in the liability calculation from the point it becomes reasonably certain the option will be exercised. Early termination of leases as part of a cost reduction programme is therefore not as clean a P&L event as management sometimes expects.
Variable Lease Payments and Index-Linked Rents
Not all lease payments are fixed. Two categories of variable lease payments are particularly common in commercial property leases.
Variable payments linked to an index or rate (such as CPI-linked rent reviews) are included in the initial lease liability measurement using the index or rate at the commencement date. When the index changes and the lease payments are actually adjusted, the lessee remeasures the lease liability using the updated payments discounted at the original discount rate (not the current IBR). The adjustment is made to the ROU asset, not through the income statement. During the period of high inflation seen from 2022 to 2024, this mechanism produced material upward remeasurements in CPI-linked leases.
Variable payments that do not depend on an index or rate (such as turnover-linked rent clauses) are not included in the lease liability measurement and are recognised as an expense as incurred.
Key Takeaways
- IFRS 16 requires most leases with a term over 12 months and an underlying asset value above approximately £5,000 new to be recognised on the balance sheet as an ROU asset and lease liability.
- The ROU asset is depreciated straight-line; the lease liability unwinds using the effective interest method. Total cost is the same as under IAS 17 but is front-loaded, with higher combined charges in early years.
- EBITDA and operating cash flow both improve under IFRS 16 relative to IAS 17; net debt increases by the lease liability. These three effects must be understood and communicated clearly in investor presentations.
- The incremental borrowing rate has a material impact on initial measurement. A 1% change in IBR on a £1m five-year lease changes the initial liability by approximately £25,000 to £30,000.
- Lease modifications, extensions and terminations all require formal remeasurement. Maintain a complete and auditable lease register from day one.
- Common fintech leases (flexible office on monthly terms, low-value IT equipment) often qualify for practical exemptions, which simplifies accounting but keeps costs above the EBITDA line.
- Variable payments linked to CPI or RPI require remeasurement each time the index is applied; this was a significant source of balance sheet movements during the 2022 to 2024 inflation cycle.
