The introduction of ASC 842 and IFRS 16 marked a fundamental shift in lease accounting. Under previous standards, operating lease payments were typically recognized as rent expense on a straight‑line basis over the lease term, with prepaid or accrued rent balances used to align cash payments with accounting periods. The primary objective was to match rental expense to the period in which the leased asset was used.

Under the current lease accounting frameworks, this paradigm has changed. With limited exceptions, leases are now recognized on the balance sheet through the recognition of a right‑of‑use (ROU) asset and a corresponding lease liability at commencement (IASB, 2016; FASB, 2016b). From that point forward, lease payments no longer determine the timing or amount of expense recognition. Instead, cash payments represent the settlement of a financial obligation already recognized on the balance sheet. Economically and accounting‑wise, lease payments become balance‑sheet‑to‑balance‑sheet movements, reducing the lease liability and cash, rather than directly giving rise to an expense.

This shift is central to understanding why traditional prepaid expense management is generally unnecessary—and inappropriate—once a lease is accounted for under ASC 842 or IFRS 16.
