What is Accounting Estimate?
An accounting estimate is a monetary amount in the financial statements that is subject to measurement uncertainty and requires management judgment. Examples include the useful life and residual value of fixed assets, allowance for credit losses, inventory net realizable value, fair value of unlisted investments, and provisions for warranties or litigation. Under IAS 8, changes in estimates are applied prospectively.
How It Works
- Identify items requiring estimation based on available evidence.
- Use reasonable, supportable assumptions and consistent methodology.
- Reassess estimates each period and revise as new information becomes available.
- Apply changes prospectively (current and future periods only).
- Disclose key estimation uncertainties under IAS 1.125.
Saudi Context
Saudi listed companies disclose the most critical accounting estimates in note 4 (or equivalent) of their IFRS statements: EOSB actuarial assumptions, expected credit loss allowance under IFRS 9, fair value of investment property, and impairment of goodwill. Audit committees probe these estimates closely as part of audit oversight.
Example
A company estimates the useful life of new IT equipment at 5 years. Three years later, technology and usage indicate only 1 more year of useful life. The change is prospective: remaining net book value is depreciated over 1 year, without restating prior periods.
