The measurement period under Ind AS 103 is often misunderstood as a general one-year window in which an acquirer can keep changing acquisition accounting. It is much narrower. The period exists so an acquirer can finish acquisition-date accounting when some values are genuinely incomplete at the first reporting date after a business combination. It does not convert later business developments, revised forecasts or post-acquisition events into adjustments to goodwill.
The current ICAI 2025-26 text of Ind AS 103 sets out the measurement-period rules in paragraphs 45-50. ICAI also hosts the standard through its 2025-26 Ind AS Compendium, a useful landing page for checking the current notified text.
When provisional accounting is allowed
If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, Ind AS 103 requires the acquirer to report provisional amounts for the items whose accounting is incomplete. This is not permission to leave the entire purchase price allocation open. The file should identify which specific assets, liabilities, non-controlling interests or consideration items remain provisional and why the information needed for final measurement is not yet available.
For example, an acquisition may close shortly before year-end while an independent valuation of an acquired customer relationship, brand or specialised property is still being finalised. The acquirer still records the business combination, using provisional acquisition-date amounts for the incomplete items rather than postponing the whole exercise.
What qualifies as a measurement-period adjustment
The key test is not simply when new information is received. The question is what the new information tells you about conditions that existed at the acquisition date. During the measurement period, provisional amounts are adjusted retrospectively when new information becomes available about facts and circumstances that existed at the acquisition date and, if known then, would have changed the amounts recognised at that date.
Ind AS 103 also permits recognition of an additional asset or liability during the measurement period if new information shows that it existed at the acquisition date and would have been recognised if that information had been available then.
What does not qualify
A post-acquisition event is not converted into acquisition accounting merely because it happens within one year. Paragraph 47 requires the acquirer to distinguish information about acquisition-date conditions from events occurring after acquisition. Information obtained soon after acquisition may be more likely to relate to acquisition-date conditions, but timing alone is not decisive.
- A valuation report completed after acquisition may produce an adjustment if it refines acquisition-date fair value using facts that already existed then.
- A new customer contract signed after acquisition is normally a post-acquisition event, not evidence of an acquisition-date condition.
- An acquired lawsuit whose underlying facts existed before acquisition may support an adjustment when better evidence about the acquisition-date obligation is obtained.
- A fall in an acquired asset's value caused by a new post-acquisition event is accounted for under the relevant Ind AS, not by reopening goodwill.
How long does the measurement period last?
The period ends as soon as the acquirer receives the information it was seeking about acquisition-date facts and circumstances, or learns that more information is not obtainable. In all cases, it cannot exceed one year from the acquisition date. The one-year point is an outer limit, not an automatic entitlement to keep acquisition accounting provisional for twelve months.
Finance teams should therefore keep a clear list of open valuation and information items, the evidence outstanding and the date each item was finalised. This helps demonstrate why an adjustment was a genuine measurement-period adjustment rather than a later estimate change.
How the adjustment affects goodwill and comparatives
Ind AS 103 requires measurement-period adjustments to be accounted for as if the business-combination accounting had been completed at the acquisition date. An increase in the provisional amount of an identifiable asset generally reduces goodwill; an increase in a provisional liability generally increases goodwill, subject to the standard's other requirements.
The retrospective approach also means prior-period comparative information may need revision. Paragraph 49 requires the acquirer to revise comparatives as needed, including related depreciation, amortisation or other income effects that would have been recognised if the revised acquisition-date amount had been used from the start.
Worked example
Assume Alpha Ltd acquires Beta Ltd on 15 December and prepares financial statements to 31 March. At 31 March, the fair value of an acquired customer-relationship asset is still being assessed, so Alpha records a provisional value of Rs. 8 crore.
In July, an independent valuation shows that the customer relationship had an acquisition-date fair value of Rs. 11 crore based on contracts, churn data and other facts that already existed on 15 December. If the evidence genuinely relates to acquisition-date conditions, Alpha increases the asset by Rs. 3 crore and reduces goodwill by Rs. 3 crore, with the related amortisation effect reflected retrospectively as required.
Now assume Beta signs a major new customer contract in June that improves expected economics. That contract did not exist on 15 December. It is not a basis for revising acquisition-date fair value through a measurement-period adjustment merely because it occurred before the one-year deadline.
Practical review checklist
- Identify exactly which acquisition-accounting items are provisional at the first reporting date.
- Document why the required acquisition-date information is incomplete.
- For every later adjustment, state whether the evidence relates to facts existing at acquisition or to a later event.
- Track the one-year outer limit from the acquisition date, not from year-end or the valuation-report date.
- Recalculate goodwill or bargain-purchase consequences when provisional asset or liability values change.
- Revise comparative depreciation, amortisation or other income effects where paragraph 49 requires retrospective treatment.
- After the period ends, do not reopen acquisition accounting for ordinary estimate changes; paragraph 50 permits revision only to correct an error under Ind AS 8.
- Retain valuation reports, deal documents and evidence supporting why each adjustment relates to acquisition-date conditions.
Common mistakes
- Treating every valuation change within twelve months as a measurement-period adjustment.
- Using one year as the default period even when the required information was obtained earlier.
- Failing to revise comparative amortisation or depreciation after changing an acquisition-date amount retrospectively.
- Adjusting goodwill for a genuinely post-acquisition event.
Practical takeaway
Use the Ind AS 103 measurement period only to complete acquisition-date accounting, not to absorb later business developments. Start with the specific provisional item, identify the missing acquisition-date evidence, test whether later information relates to conditions that existed when control was obtained, make any qualifying adjustment retrospectively, and close the item as soon as the information is available. The one-year rule is the maximum boundary, not a general reopening window for goodwill.
