AS 5 — Net Profit/Loss, Prior Period Items & Policy Changes

Think of AS 5 as the 'truth-in-reporting' standard. It answers three practical questions every accountant faces: What exactly goes into my Profit & Loss for this year? What do I do when I discover I made a mistake in last year's accounts? And can I simply change my accounting method when it suits me?

AS 5 splits the P&L into two buckets: ordinary activities (your day-to-day business — sales, purchases, salaries) and extraordinary items (events that are both unusual in nature AND infrequent in occurrence — think a factory destroyed by a flood in a desert region, or expropriation of assets by the government). The standard is strict: calling something 'extraordinary' is rare. Natural calamities in calamity-prone areas, write-downs of inventory, or losses on foreign exchange are explicitly not extraordinary. Most items students label as extraordinary are simply 'exceptional items' within ordinary activities — still disclosed separately, but not as extraordinary. This distinction is a favourite 4-mark MCQ trap.

Prior period items are income or expenses arising from errors or omissions in the financial statements of one or more prior periods. The classic example: Mr. Sharma's accountant forgot to accrue ₹2,00,000 of salary in FY 2023-24, discovered in FY 2024-25. This ₹2,00,000 is a prior period item — it must be shown separately in the current year's P&L with a clear description, not silently merged into salary expense. It still flows through P&L (not directly to reserves), but it must be visible. Changes in accounting estimates (like revising the useful life of a machine) are not prior period items — they are handled prospectively.

Changes in accounting policies are the most tested part of AS 5. You can change a policy only if: (a) it is required by a statute or accounting standard, or (b) the change results in a more appropriate presentation. You cannot change just because it gives a better profit number! When a change is made, the cumulative effect of the change is disclosed. If the amount is material and ascertainable, prior period figures should be restated and the effect disclosed. The key phrase for exams: 'as if the new policy had always been applied.' Changing from SLM to WDV depreciation? Restate comparative figures and disclose the impact — don't just apply it going forward silently.

📊 Worked example

Example 1 — Prior Period Item

Rajesh & Co. Pvt. Ltd. is preparing accounts for FY 2024-25. During audit, it is discovered that rent expense of ₹1,80,000 for March 2024 was never recorded in FY 2023-24 (already filed).

Working:

  • The omission relates to a prior period (FY 2023-24) → it is a prior period item
  • It is NOT a change in estimate; it is an error/omission
  • Treatment: Record ₹1,80,000 as expense in FY 2024-25 P&L, but show it separately as 'Prior Period Expense — Rent (FY 2023-24)'
  • Do NOT adjust opening retained earnings directly

Journal Entry in FY 2024-25:

Prior Period Expense (Rent) A/c Dr. ₹1,80,000

To Rent Payable A/c ₹1,80,000

(Shown as a separate line in P&L with disclosure of nature)

Final Answer: ₹1,80,000 disclosed as prior period expense in current year P&L.

Example 2 — Change in Accounting Policy

Ms. Iyer's company changed its inventory valuation from FIFO to Weighted Average Cost method in FY 2024-25. Closing inventory under FIFO as at 31-Mar-2024 was ₹12,00,000. Under Weighted Average, the same inventory would have been ₹10,50,000.

Working:

  • Difference = ₹12,00,000 − ₹10,50,000 = ₹1,50,000
  • This is the cumulative effect of the change in accounting policy
  • Opening inventory for FY 2024-25 must be restated to ₹10,50,000
  • The ₹1,50,000 impact is shown in P&L of FY 2024-25 as effect of change in accounting policy, with full disclosure
  • Comparative figures for FY 2023-24 are restated as if Weighted Average had always been used

Final Answer: Disclose ₹1,50,000 as the effect of change in accounting policy; restate prior period comparatives.

⚠️ Common exam mistakes

  • Students label every unusual loss as 'extraordinary'. Don't. Extraordinary items must be both unusual in nature and infrequent in occurrence. A factory fire in a fire-prone city is not extraordinary. The bar is very high — almost nothing in routine business qualifies.
  • Treating prior period items as direct reserve adjustments. Many students debit/credit retained earnings directly. Wrong — AS 5 requires prior period items to pass through the current year P&L, separately disclosed. Direct reserve adjustment is not permitted under Indian AS 5 (unlike Ind AS 8).
  • Confusing change in accounting estimate with change in accounting policy. Revising a machine's useful life from 10 to 8 years = estimate change (prospective, no restatement needed). Switching from SLM to WDV = policy change (restatement required). Don't mix these up in theory questions.
  • Thinking any management decision can trigger a policy change. AS 5 explicitly says a change is allowed only if required by statute/AS or it gives a more appropriate presentation. 'It increases our profit' is not a valid reason — this is a common theory-question trap.
  • **Forgetting to disclose the nature and amount of prior period and extraordinary items separately.** Even if you correctly identify the item, not mentioning the disclosure requirement in your answer costs marks. Always state: the item must be shown separately with description and amount in the P&L.
