Under the lease accounting standards that took effect in 2019, ASC 842 in the US and IFRS 16 internationally, a lessee records the liability for its future lease payments, discounted to present value, together with a matching right-of-use asset. Before that, many leases were kept off the balance sheet.
The two standards differ. IFRS 16 treats almost all leases like a financed purchase, with depreciation and interest shown separately. Under ASC 842, leases classified as operating still show a single straight-line lease cost in the income statement, but the liability is on the balance sheet either way.
The number depends on assumptions: the lease term, including renewal options that the company is reasonably certain to use, and the discount rate.
Check the discount rate and term used, find the split between current and non-current portions and compare the liability with the commitment table in the notes.
