What IFRS 16 software needs to do, and why a spreadsheet stops being enough

IFRS 16 requires a lessee to recognize a right-of-use asset, representing the right to use the leased space, and a lease liability, representing the obligation to make lease payments, for substantially all leases longer than 12 months unless the underlying asset is low value. It became effective for annual reporting periods starting on or after January 1, 2019, replacing IAS 17. Under the prior standard, a lease classified as "operating" could stay off the balance sheet entirely. IFRS 16 closed that door.

The difference that actually matters: one model, not two#

IFRS 16 replaced IAS 17’s operating-versus-finance lease split with a single lessee accounting model: every qualifying lease is treated the same way on the balance sheet. ASC 842, the equivalent U.S. GAAP standard, also brought leases onto the balance sheet, but it kept the lessee-side distinction between operating and finance leases, which affects how the expense is presented on the income statement.

A multinational occupier can’t run one calculation engine tuned for U.S. leases and assume it works for the rest of the portfolio. A lease in Germany, the UK, or Singapore falls under IFRS 16’s single model; the same company’s U.S. leases fall under ASC 842’s dual model.

What IFRS 16 software actually needs to handle#

• Remeasurement on modification, flowing through to both the right-of-use asset and lease liability on the date it happens
• Discount rate updates, since remeasurement can require an updated rate depending on the modification type
• Disclosure traceability, so every figure traces back to the lease clause and calculation that produced it
• Jurisdiction-aware classification, applying the right rules lease by lease in a mixed IFRS/GAAP portfolio

Why a periodic spreadsheet update falls behind#

A spreadsheet-based process usually updates the lease schedule once a quarter, recalculating everything at that checkpoint. A lease modification that happens mid-quarter doesn’t get reflected until the next scheduled update, which means the books are technically out of compliance for however long that gap lasts.

Where REAL fits#

REAL’s Lease Accounting agent classifies and calculates every new lease from the lease itself, posts journal entries on schedule, and remeasures modifications the moment they happen, tying every adjustment back to the clause that produced it. Because REAL also runs Lease Intelligence on the same underlying lease data, a renewal option exercised or a rent change flows directly into the accounting remeasurement without being re-entered.
