Introduction: Why AS 5 Is Important
Many items appear in the Profit & Loss Account that do not belong to normal business operations or do not relate to the current year.
AS 5 helps us answer:
- What should be included in current year profit?
- What belongs to prior years?
- What is so unusual that it must be shown separately?
In short: AS 5 ensures clarity, comparability, and honesty in reported profits.
Objective of AS 5
To prescribe:
- The basis for determining net profit or loss for a period
- Disclosure and treatment of:
- Prior Period Items
- Extraordinary Items
- Changes in Accounting Estimates
Net Profit or Loss for the Period
Net Profit or Loss includes:
- All income and expenses arising in the ordinary course of business
- After considering adjustments required by Accounting Standards
Example:
- Sales revenue
- Cost of goods sold
- Administrative expenses
- Depreciation
All these form part of normal profit calculation.
Prior Period Items (Very Important Topic)
Prior Period Items are:
Income or expenses that arise in the current period but relate to errors or omissions of one or more prior periods.
Examples of Prior Period Items
- Salary of last year omitted and paid this year
- Electricity expense of previous year booked this year
- Income understated in earlier year due to mistake
These arise only because of errors or omissions, not because of estimates.
Treatment of Prior Period Items
- Should be separately disclosed in the P&L Account
- Their nature and amount must be clearly shown
Example disclosure:
“Prior period expenses amounting to ₹50,000 relating to salary omitted last year.”
Extraordinary Items
Extraordinary items are:
Income or expenses arising from events that are clearly distinct from ordinary activities and not expected to recur frequently.
Examples of Extraordinary Items
- Loss due to earthquake or flood
- Compensation received due to nationalisation
- Loss from expropriation of assets
Not Extraordinary:
- Loss due to fire (normal business risk)
- Strike by workers
- Theft
Treatment of Extraordinary Items
- Disclosed separately in the P&L Account
- Nature and amount clearly mentioned
This helps users understand normal business performance.

Changes in Accounting Estimates
Accounting estimates are approximations used due to uncertainty.
Examples:
- Useful life of an asset
- Provision for doubtful debts
- Warranty provisions
Treatment
- Effect of change is included in:
- Current period, or
- Current + future periods (if applicable)
- No retrospective adjustment
Example:
Change in estimated life of machinery → Depreciation revised prospectively.
Important Distinction (Exam Favourite)
- Basis Prior Period Item Accounting Estimate
- Reason Error or omission New information
- Period affected Past Present/Future
- Adjustment Separate disclosure Prospective
- AS Covered AS 5 AS 5
Common Student Mistakes
- Treating change in estimate as prior period item
- Classifying fire loss as extraordinary
- Not disclosing prior period items separately
- Mixing AS 4 and AS 5 concepts
Exam Tip
If asked:
“Distinguish between Prior Period Items and Extraordinary Items”
Write:
- Definition
- Reason for occurrence
- Accounting treatment
- Examples
This alone can fetch full marks.
