SFRS(I) 1-8 sets out the criteria for selecting and changing accounting policies, together with the accounting treatment and disclosure of changes in accounting policies, changes in accounting estimates, and corrections of errors. The distinction it draws — between a change in policy (applied retrospectively), a change in estimate (applied prospectively), and the correction of an error (corrected retrospectively) — is fundamental to how financial statements maintain comparability over time. It is the Singapore equivalent of IAS 8 under IFRS and Ind AS 8 in India, and is in substance IAS 8 as applied in Singapore.
Objective and scope
The objective is to prescribe the criteria for selecting and changing accounting policies, together with the accounting treatment and disclosure of changes in accounting policies, changes in accounting estimates, and corrections of prior period errors. The standard is intended to enhance the relevance and reliability of an entity's financial statements, and the comparability of those statements over time and with the financial statements of other entities.
Accounting policies
Accounting policies are the specific principles, bases, conventions, rules, and practices applied by an entity in preparing and presenting financial statements. When an SFRS(I) specifically applies to a transaction, other event, or condition, the accounting policy applied is determined by applying that SFRS(I). In the absence of a specific SFRS(I), management uses judgement in developing and applying an accounting policy that results in relevant and reliable information, referring first to the requirements in SFRS(I) dealing with similar issues, and then to the definitions, recognition criteria, and measurement concepts in the Conceptual Framework.
An entity applies its accounting policies consistently for similar transactions, other events, and conditions, unless an SFRS(I) specifically requires or permits categorisation of items for which different policies may be appropriate.
Changes in accounting policies
An entity changes an accounting policy only if the change is required by an SFRS(I), or results in the financial statements providing reliable and more relevant information about the effects of transactions on the entity's financial position, financial performance, or cash flows.
A change in accounting policy is generally applied retrospectively — as if the new policy had always been applied. This means adjusting the opening balance of each affected component of equity for the earliest prior period presented, and the other comparative amounts, as if the new policy had always been in place. Where it is impracticable to determine the period-specific or cumulative effects of the change, specific relief from full retrospective application applies. (A change required by an SFRS(I) that includes specific transitional provisions is applied in accordance with those provisions.)
Changes in accounting estimates
A change in accounting estimate is an adjustment of the carrying amount of an asset or a liability, or the amount of the periodic consumption of an asset, that results from the assessment of the present status of, and expected future benefits and obligations associated with, assets and liabilities. Changes in accounting estimates result from new information or new developments and are not corrections of errors. Examples include changes in estimates of bad debts, inventory obsolescence, the useful lives of depreciable assets, and warranty obligations.
The effect of a change in an accounting estimate is recognised prospectively by including it in profit or loss in the period of the change (if the change affects that period only) or in the period of the change and future periods (if it affects both). Prospective recognition means the change affects only current and future periods — prior periods are not restated. This is the key contrast with a change in accounting policy (retrospective).
Prior period errors
Prior period errors are omissions from, and misstatements in, the entity's financial statements for one or more prior periods arising from a failure to use, or misuse of, reliable information that was available when those financial statements were authorised for issue and could reasonably be expected to have been obtained and taken into account. Such errors include the effects of mathematical mistakes, mistakes in applying accounting policies, oversights or misinterpretations of facts, and fraud.
An entity corrects material prior period errors retrospectively in the first set of financial statements authorised for issue after their discovery — by restating the comparative amounts for the prior period(s) presented in which the error occurred, or, if the error occurred before the earliest prior period presented, by restating the opening balances of assets, liabilities, and equity for the earliest prior period presented. Where it is impracticable to determine the effects of an error, specific relief applies. A correction of a prior period error is distinguished from a change in accounting estimate — estimates by their nature may need revision as more information becomes available, and such revisions are not corrections of errors.
A brief illustration
A Singapore company revises the estimated useful life of a machine from ten years to eight years because of new information about its wear — a change in accounting estimate, so it adjusts depreciation prospectively over the machine's remaining life, without restating prior years. Separately, the company decides to change its inventory cost formula from weighted average to FIFO because FIFO provides more relevant information — a change in accounting policy, applied retrospectively, restating comparatives as if FIFO had always been used. Finally, the company discovers that a supplier invoice was omitted from last year's accounts — a prior period error, corrected retrospectively by restating the prior-year comparatives. The three situations, superficially similar, are treated in three different ways.
How SFRS(I) 1-8 relates to IFRS and Ind AS
SFRS(I) 1-8 is identical to IAS 8 under IFRS, and therefore very closely aligned with Ind AS 8 in India — the same hierarchy for selecting accounting policies, the same retrospective treatment for changes in policy, the same prospective treatment for changes in estimate, and the same retrospective correction of prior period errors. Because both Singapore and India converge to the IFRS text, the treatment is materially the same across the three frameworks.
Common pitfalls
Recurring issues include treating a change in accounting policy prospectively (it should generally be retrospective), or a change in estimate retrospectively (it should be prospective); misclassifying a correction of an error as a change in estimate to avoid restating comparatives; changing an accounting policy without it being required by an SFRS(I) or resulting in more relevant and reliable information; and inadequate disclosure of the nature and effect of a change or error correction.
Why this is cleaner on a unified system
Applying changes in policy, changes in estimate, and error corrections correctly — including the retrospective restatement of comparatives — is more reliable when the underlying data and prior-period figures can be produced consistently from one connected system. When the accounts sit in a single source of truth, restating comparatives for a policy change or error correction, and applying an estimate change prospectively, is more straightforward than reconciling figures assembled from separate tools.
