AS 5 Net Profit or Loss for the Period, Prior Period Items and Changes in Accounting Policies: formula sheet

Full chapter guide

Key formulas

Net profit or loss for the period: Net profit or loss = Profit or loss from ordinary activities ± Extraordinary items; Prior period items have no separate term here. They are included in determining profit or loss from ordinary activities (unless extraordinary in nature) and are disclosed separately so their effect on current profit can be seen.
Ordinary activities: Business activities + related activities in furtherance of, incidental to, or arising from them; Test: does the item relate to the business the enterprise normally carries on? If yes, it is ordinary.
Extraordinary items: Event clearly distinct from ordinary activities AND not expected to recur frequently or regularly; Both conditions must hold. Nature of the event decides it, not the amount.
Prior period items: Current-period income or expense caused by an error or omission in an earlier period's financial statements; A change in estimate is not a prior period item.
Accounting policies: Specific accounting principles + methods of applying them; Example: choosing FIFO or weighted average is a policy. Revising an asset's useful life is an estimate.
Permitted reasons to change an accounting policy (AS 5): Required by statute, OR required for compliance with an Accounting Standard, OR results in a more appropriate presentation of the financial statements; AS 5 permits a change in accounting policy only on these grounds. AS 5 also requires disclosure of a change in policy that has a material effect. If the amount cannot be ascertained, disclose that fact.
Extraordinary item (definition): Extraordinary item = income or expense from an event clearly distinct from ordinary activities AND not expected to recur frequently or regularly; Both conditions must hold. If either fails, the item is not extraordinary.
Exceptional item (rule): Ordinary-activity item of such size, nature or incidence that separate disclosure is needed to explain the period's performance; It stays part of ordinary activities. Disclose nature and amount separately. AS 5 (para 12) lists the circumstances; the label "exceptional" is the common name.
Disclosure of extraordinary items: Show in the statement of profit and loss as part of net profit or loss for the period, with nature and amount of each item stated separately; The separate disclosure must let a reader see the effect on current profit or loss.
Profit flow (Schedule III, Division I, for companies following AS): Profit before exceptional and extraordinary items and tax + Exceptional items (income) − Exceptional items (expense) = Profit before extraordinary items and tax; then ± Extraordinary items = Profit before tax; This is the line order in the Schedule III Division I Statement of Profit and Loss format used by companies following AS. It is not a fixed requirement for every entity, so follow the format the question states.
Prior period items (definition): Prior period item = income or expense of current period arising from error or omission in earlier period(s); Not an ordinary revision of a figure. The source must be an error or omission.
Treatment of prior period items: Recognise in current period profit or loss and disclose separately (separate line or note), with nature and amount, so the impact on current profit or loss can be perceived; The item is dealt with through the current period, not by reworking earlier years' accounts.
Treatment of change in estimate: Effect recognised prospectively: current period, or current and future periods; No rework of past accounts. Same income or expense head as the earlier estimate.
Revised depreciation after change in useful life: Revised annual depreciation = (Carrying amount at start of year − residual value) ÷ remaining useful life; Applies from the year of change onwards on the straight-line basis. Use this formula when the revision is made at the start of the year. If the revision is made during the year, depreciate the carrying amount at the date of change over the remaining life, pro rata for the period.
Disclosure of change in estimate: Disclose nature and amount of material effect; if not quantifiable, say so; Applies when the effect on the current period or future periods is material.
Valid reasons for change: Statute required OR Accounting Standard required OR More appropriate presentation; Any one reason is enough. A policy change for any other reason is not permitted.
Impact of change in policy: Impact on profit = Profit under new policy − Profit under old policy; For inventory, work out the difference in closing stock and the difference in opening stock. Impact = closing difference − opening difference.
Disclosure rule: Disclose change + material impact in the period of change; If the impact is not ascertainable, wholly or partly, state that fact. If no material effect now but expected later, disclose the fact of change.
Policy vs estimate: Policy change: how to measure or present. Estimate change: revised approximation. If unclear, treat as estimate change.; Estimate changes affect the current and affected future periods. They are not applied retrospectively.
Change in depreciation method: Surplus or deficiency = Depreciation under new method since asset was first used − Depreciation already charged (a negative result is a surplus); AS 6 treats this as a change in accounting policy. AS 6 permits the change only if it is required by statute, is needed to comply with an accounting standard, or would result in a more appropriate preparation or presentation of the financial statements. Depreciation is recomputed under the new method from the date the asset came into use. The surplus (credited to the statement of profit and loss) or deficiency (charged to it) is adjusted in the year of change. The change is treated as a change in accounting policy, and its effect is quantified and disclosed. The new method then applies from that year on.

Quick revision

AS 5 deals with classification and disclosure in the statement of profit and loss, not with valuation.
Net profit or loss for the period comprises (a) profit or loss from ordinary activities and (b) extraordinary items. Prior period items are included in determining it and are separately disclosed.
Extraordinary items arise from events clearly distinct from ordinary activities and are not expected to recur frequently or regularly. They are disclosed separately.
Exceptional items belong to ordinary activities. Their size, nature or incidence requires separate disclosure of nature and amount.
Prior period items are income or expenses arising in the current period from errors or omissions in earlier periods' financial statements. They are included in determining net profit or loss for the period and disclosed separately so their effect on current profit is visible.
A change in accounting estimate is not a prior period item. Its effect goes into the period of change, and into future periods if they are affected.
Disclose the nature and amount of a change in estimate that has a material effect. If the amount cannot be quantified, disclose that fact.
A policy change is allowed only if required by statute, required by an accounting standard, or gives a more appropriate presentation.
Adopting a policy for transactions that differ in substance from earlier ones, or for events that did not occur before, is not a change in policy.
Disclose a material effect of a policy change. If it cannot be ascertained wholly or in part, say so.
A change in the method of depreciation is treated as a change in accounting policy, as per AS 6.
Schedule III has a line for exceptional items, and extraordinary items are disclosed separately as per AS 5 where they arise. Ind AS prohibits extraordinary items, and AS 5 does not apply to Ind AS companies.

Common mistakes

Calling any large or unusual item extraordinary. Fix: Apply both tests: clearly distinct from ordinary activities, and not expected to recur frequently or regularly. A big item from normal business stays ordinary, though it may need separate disclosure.
Treating a change in estimate as a prior period item. Fix: A prior period item comes from an error or omission. A change in estimate comes from new information or experience, and its effect goes into the period of change (and future periods if affected).
Treating any large loss as extraordinary. Fix: Apply both tests: clearly distinct from ordinary activities and not expected to recur frequently or regularly. A large but routine item is at most exceptional.
Using the terms extraordinary and exceptional as if they mean the same thing. Fix: Remember the location: extraordinary is outside ordinary activities, exceptional is inside them.
Treating every earlier-year item as a prior period item. Fix: Check the cause. Only errors or omissions make it a prior period item. Settlement of an estimated liability at a different amount is ordinarily a change in estimate, unless the original estimate was itself an error.
Reworking the opening balances or earlier year profit. Fix: Pass the entry in the current year and disclose the item separately. Do not rework the earlier year's profit for it.
Treating a change in useful life or residual value as a change in accounting policy. Fix: Ask whether the method changed or only an input changed. A new method is a policy change. A revised life or residual value is an estimate change.
Allowing a policy change just because it improves profit. Fix: Always test for statute, accounting standard or more appropriate presentation. Improved profit is not a reason.

Exam tips

Learn the four definitions as keyword sets: ordinary (business plus related), extraordinary (clearly distinct plus non-recurring), prior period (error or omission), policy (principles plus methods).
In MCQs, the trap is usually estimate versus prior period item, or large amount versus extraordinary. Check the cause of the item first.
In a written case, state the definition before the conclusion. Markers give step marks for the reasoning.
Remember where each item sits: extraordinary and prior period items are disclosed separately, and AS 5 does not cover their tax effects.
Memorise the three valid reasons for a change in accounting policy (from AS 5): statute, compliance with an AS, or more appropriate presentation. They are asked directly.
In MCQs, the usual trap is swapping the two terms. Check whether the event is outside ordinary activities (extraordinary) or inside them (exceptional).
In written answers, quote the definition first, then apply it. Marks are given for the reasoning, not only for the label.
Always write the nature and amount of each item as a separate disclosure line. This is a common mark-earning step.
