IFRS 16 Explained: What Changed and Why It Matters

IFRS 16 explained: what changed and why

Lease accounting might not be the most glamorous corner of finance, but IFRS 16 changed it in ways that every finance team needs to understand. Introduced by the International Accounting Standards Board and effective from January 2019, this accounting standard fundamentally reshaped how organisations recognise, measure, and report their lease obligations. Whether you are preparing group financial statements or analysing a company’s balance sheet, getting a clear picture of IFRS 16 is essential for making sense of modern financial reporting.

This IFRS 16 overview walks through what changed, why it matters, and what the practical implications look like for finance teams managing complex reporting environments today.

The Shift from IAS 17 to IFRS 16

Before IFRS 16 arrived, lease accounting was governed by IAS 17, a standard that divided leases into two categories: finance leases and operating leases. Finance leases appeared on the balance sheet, but operating leases were largely kept off it, disclosed only in the notes to financial statements. This created a significant transparency problem.

The core issue was that operating leases represented real, contractual financial obligations, yet they were invisible to anyone reading the face of the balance sheet. Analysts and investors had to make manual adjustments to estimate the true scale of a company’s lease commitments. The IFRS 16 changes were designed to close that gap entirely, bringing the vast majority of leases onto the balance sheet and giving financial statements a far more complete picture of a company’s obligations.

How IFRS 16 Redefines Lease Recognition

The most significant conceptual shift in IFRS 16 is the move to a single lessee accounting model. Under this model, almost all leases must be recognised on the balance sheet, with two new items appearing for lessees: a right-of-use asset and a corresponding lease liability.

The right-of-use asset represents the lessee’s right to use the underlying asset over the lease term. The lease liability reflects the present value of future lease payments. At the commencement of a lease, both are recognised simultaneously, and from that point the asset is depreciated while the liability is unwound using an effective interest method. Only short-term leases of twelve months or less, and leases of low-value assets, are exempt from this treatment.

This redefinition of lease recognition means that operating leases, which were previously invisible on the balance sheet, now show up as substantial assets and liabilities. For companies with large property portfolios, vehicle fleets, or equipment under long-term rental agreements, this change was transformative.

Impact on Financial Statements and Key Ratios

The balance sheet is the most visibly affected statement under IFRS 16. Total assets increase because of the right-of-use asset, and total liabilities increase because of the lease liability. For companies with extensive lease commitments, these additions can be material.

The income statement also changes shape. Under IAS 17, operating lease payments flowed straight through as operating expenses, reducing EBIT directly. Under IFRS 16, the lease payment is replaced by depreciation of the right-of-use asset and interest on the lease liability. Depreciation sits in operating expenses, but interest moves below the operating line. The result is that EBITDA and EBIT both improve for companies with significant operating leases, while net profit may remain broadly similar or even fall slightly in the early years of a lease due to front-loaded interest charges.

Key financial ratios shift as a consequence. Leverage ratios increase because debt-like lease liabilities are now on the balance sheet. Return on assets can decline because total assets are higher. Interest cover ratios change because interest expense rises. Anyone performing financial analysis or covenant monitoring needs to account for these effects carefully, particularly when comparing companies across periods that straddle the transition date.

Practical Challenges Companies Faced at Transition

Transitioning to IFRS 16 was not simply a matter of applying a new formula. Companies faced significant operational and data challenges in getting ready for the standard.

Identifying and cataloguing leases

Many organisations discovered that their lease data was fragmented across departments, spreadsheets, and local entities. Before any accounting could happen, finance teams needed to identify every contract that contained a lease component, which required coordination between legal, property, procurement, and finance functions. For multi-entity groups, this exercise multiplied in complexity.

Calculating discount rates

The standard requires lessees to discount future lease payments using the interest rate implicit in the lease, or if that is not readily determinable, the lessee’s incremental borrowing rate. Determining appropriate incremental borrowing rates across different currencies, jurisdictions, and lease terms was a significant judgement exercise that required input from treasury teams and external advisers.

Managing ongoing compliance

Lease modifications, reassessments, and renewals all trigger remeasurement under IFRS 16. For groups with hundreds or thousands of leases, keeping this data current and audit-ready on an ongoing basis proved to be one of the most persistent operational challenges beyond the initial transition.

What IFRS 16 Means for Financial Analysis Today

In 2026, IFRS 16 is no longer new, but its implications remain central to how financial statements are read and how group reporting is managed. Analysts comparing companies across industries need to be aware that balance sheets now carry lease liabilities that were previously off-balance-sheet, and that EBITDA figures are structurally higher for lease-heavy businesses than they were under IAS 17.

For finance teams in multi-entity organisations, the ongoing compliance burden is real. Lease data needs to be maintained at entity level, consolidated accurately at group level, and presented consistently across jurisdictions. This is an area where manual processes and spreadsheet-based approaches introduce meaningful risk, particularly when lease portfolios are large or distributed across multiple countries.

Our IFRS 16 lease accounting module within AARO is built to address exactly this challenge. It automates the calculation of right-of-use assets and lease liabilities, handles remeasurements triggered by modifications, and feeds the results directly into the group consolidation process, so that IFRS 16 compliance is embedded in the close rather than bolted on as a separate exercise.

For growing organisations managing an expanding lease portfolio across multiple entities, having a structured, automated approach to lease accounting under IFRS 16 is not just an efficiency gain. It is a foundation for reliable, audit-ready reporting that scales as the business does. The standard has settled in, but the operational discipline it demands from finance teams continues to evolve alongside the organisations that operate under it.
