A share-count reconciliation is the starting point
Under AS 20, basic EPS divides profit or loss attributable to equity shareholders by the weighted average equity shares outstanding. A cash issue during the year is generally time-weighted from its relevant inclusion date. A bonus issue or share split, which does not bring corresponding resources, requires retrospective adjustment of the share numbers for the periods presented. Closing share capital divided by face value is therefore not automatically the correct denominator.
Apply AS 20 in the correct reporting framework
This article uses ICAI’s AS 20 Earnings Per Share text, particularly paragraphs 10–25 on basic EPS, 26–42 on dilution and 44–48 on restatement and disclosure. Sources were checked on 22 October 2026. It concerns companies reporting under the Accounting Standards framework; an Ind AS reporter must apply its own relevant framework, including Ind AS 33. Do not transfer the conclusion merely by renaming the standard.
The AS 20 applicability text provides a diluted-EPS disclosure relaxation for a Small and Medium Sized Company under the accounting-standard framework and separate non-company entity relaxations. That classification is not automatically the same as a Companies Act section 2(85) small company. Establish applicability and any relaxation first. The computations below demonstrate the measurement where the corresponding EPS information is required or presented; they do not remove a valid presentation relaxation.
Reconcile earnings before counting shares
Profit after tax is not always the equity-attributable numerator. AS 20 requires deduction of the relevant preference dividends and any attributable tax. For cumulative preference shares, the period’s required dividend is considered whether or not provided; for non-cumulative shares, use the amount provided for the period. A payment in the current year relating to an earlier cumulative period is not automatically another current-period deduction. Use the actual instrument terms and period.
The examples assume one equity class, no extraordinary or discontinued components and no tax adjustment except where expressly stated. For consolidated information, use the relevant consolidated basis rather than inserting standalone earnings into a group denominator. Where equity classes have different dividend rights, analyse the allocation instead of combining all nominal capital indiscriminately.
Different events change the denominator differently
For an ordinary cash issue, AS 20 generally starts inclusion when consideration is receivable, taking the terms and substance into account. Debt conversion, liability settlement, services and asset acquisitions have their stated inclusion principles. Obtain the source event, entitlement terms and date; cash-bank entry date alone is not universally decisive. AS 20 describes day-based weighting and permits a reasonable approximation in many circumstances. The month-start cash and rights examples below use an expressly stated half-year approximation, not an assertion that every six-month period contains equal days.
Bonus issues and splits change share numbers without corresponding new resources. Adjust earlier share numbers as if the event occurred at the beginning of the earliest period presented. Do not weight a midyear bonus merely for the months after allotment. AS 20 paragraph 44 also addresses bonus/split events after the balance-sheet date but before board approval of the financial statements. A later ordinary cash issue is a different event and does not automatically restate historical EPS.
A discounted rights issue generally has a bonus element. Calculate theoretical ex-rights fair value from the pre-issue fair value of existing shares plus rights proceeds, divided by total post-issue shares. The adjustment factor is pre-rights fair value per share divided by theoretical ex-rights value. Apply that factor to the earlier share count and comparative denominator as required; do not round it early or apply the entire cash proceeds as a numerator gain.
Dilution uses assumed effects, not every possible share
For options, the standard assumes proceeds from exercise and compares the issuable shares with the number obtainable at average fair value. Only the incremental shares representing the no-consideration element enter the stated dilution working. This is a computational assumption; it does not report an actual share buyback or actual cash receipt. Use the appropriate period weighting if the options were not outstanding throughout the year.
Convertible instruments can also require numerator adjustments for interest, dividends and related tax effects. Each series is considered separately and in the required dilution sequence. Do not add every potential share without testing the result. AS 20 uses continuing ordinary earnings as the control figure: a conversion that increases EPS or decreases loss per share is anti-dilutive and is ignored in diluted EPS. A denominator increase that makes a loss look smaller is not dilution.
Make the disclosed figure traceable
Retain a profit-to-numerator bridge, a dated share schedule, bonus and rights factors, and a basic-to-diluted reconciliation. The standard also addresses face presentation, negative EPS and nominal value disclosure. Reconcile the supporting schedule to the registers and financial statements. An EPS spreadsheet can be arithmetically correct yet wrong if it uses the wrong start date, omits a preference entitlement, ignores a bonus factor or includes anti-dilutive instruments.
Worked illustrations
These illustrations use fictional facts and expressly stated assumptions. Amounts are Indian rupees unless a different currency or unit is specified. They are independent examples, not findings about any actual client.
Illustrative example 1: preference entitlement changes the numerator
Profit after tax is ₹24,00,000. Assume ₹2,00,000 is the current period’s relevant preference dividend and no attributable tax adjustment arises. Equity-attributable earnings are ₹22,00,000. With 10,00,000 fully paid equity shares throughout, basic EPS is ₹2.20. Using the entire ₹24,00,000 would incorrectly show ₹2.40.
Illustrative example 2: a cash issue is time-weighted
For an April–March year, 10,00,000 shares exist throughout and an additional 6,00,000 ordinary shares are included from 1 October. Assume a reasonable six-twelfths weighting and no bonus element. Weighted shares = 10,00,000 + 6,00,000 × 6/12 = 13,00,000. Equity-attributable earnings ₹26,00,000 give basic EPS ₹2.00. Using closing shares of 16,00,000 would give ₹1.625 before rounding and would ignore the earlier capital base.
Illustrative example 3: bonus shares restate both years
There are 10,00,000 shares before a one-new-for-four-existing bonus issue, with no other changes. The factor is 5/4 and adjusted shares 12,50,000. Current equity earnings ₹25,00,000 give EPS ₹2.00 for the full year. Prior-year earnings ₹20,00,000 give restated comparative EPS ₹1.60 instead of the original ₹2.00. The bonus is not merely weighted from its midyear allotment date.
Illustrative example 4: a rights issue contains a bonus factor
There are 4,00,000 shares with fair value ₹50 immediately before exercise. A fully subscribed one-for-four rights issue at ₹30 creates 1,00,000 shares, included from 1 October in an April–March year. Theoretical ex-rights value = (4,00,000 × ₹50 + 1,00,000 × ₹30) ÷ 5,00,000 = ₹46. Factor = 50/46 = 25/23. With the stated half-year approximation, weighted shares = 4,00,000 × 25/23 × 6/12 + 5,00,000 × 6/12 = 4,67,391.304348…. Current equity earnings ₹14,00,000 produce EPS ₹2.995348… or ₹3.00 to two decimals. Comparative earnings ₹9,20,000 divided by 4,00,000 × 25/23 give restated EPS ₹2.116 or ₹2.12, rather than the original ₹2.30.
Illustrative example 5: options add only incremental shares
Equity-attributable earnings are ₹20,40,000 and basic weighted shares 10,00,000. Assume 50,000 options outstanding all year, exercise price ₹60, average fair value ₹100, no other dilution and no numerator change. Assumed proceeds ₹30,00,000 correspond to 30,000 shares at average fair value. Incremental shares = 50,000 − 30,000 = 20,000. Basic EPS is ₹2.04 and diluted EPS ₹20,40,000 ÷ 10,20,000 = ₹2.00. Adding all 50,000 option shares would overstate dilution.
Illustrative example 6: a smaller loss per share is anti-dilutive
Assume continuing ordinary equity loss ₹10,00,000, basic weighted shares 10,00,000 and options that would otherwise add 20,000 incremental shares without changing the numerator. Basic loss per share is ₹1.00. Including the options would show about ₹0.980392 loss per share, a smaller loss. Their effect is anti-dilutive, so exclude them and disclose diluted loss per share of ₹1.00 on these facts, not ₹0.98.

Sixteen practitioner FAQs
1. Is closing paid-up capital the normal EPS denominator?
No. Establish weighted shares and any retrospective adjustment under AS 20.
2. Does profit after tax always equal the numerator?
No. Relevant preference dividends and attributable tax can require adjustment.
3. Are undeclared cumulative preference dividends ignored?
No. The period’s required cumulative dividend is considered whether or not provided.
4. When are ordinary cash-issued shares generally included?
From when consideration is receivable, considering the terms and substance of the transaction.
5. Can months be used instead of days in every case?
Not automatically. AS 20 allows a reasonable approximation in many circumstances; document why it is appropriate.
6. Is a midyear bonus weighted only after issue?
No. The no-corresponding-resource adjustment applies retrospectively as the standard requires.
7. Are comparative EPS figures affected by a bonus?
Yes. Adjust the relevant prior-period share count for the proportionate change.
8. Can a bonus after year-end affect the EPS just being approved?
Paragraph 44 addresses a bonus or split before board approval; apply its specific restatement requirement.
9. Does an ordinary post-year-end cash issue have the same effect?
No. Paragraphs 46–47 distinguish such transactions from the specified bonus/split restatement events.
10. What does the rights adjustment factor represent?
The bonus element embedded in the rights pricing, based on the pre-rights and theoretical ex-rights fair values.
11. Should the rights factor be rounded to two decimals immediately?
No. Retain precision through the denominator and round the displayed EPS consistently.
12. Do all option shares enter diluted EPS?
No. Under the stated method, calculate the incremental no-consideration element and apply time weighting where relevant.
13. Are assumed option proceeds an actual cash transaction?
No. They are part of the standard’s dilution computation.
14. Can adding potential shares make a loss look smaller?
That result is anti-dilutive and is excluded under the standard’s control test.
15. Does a small company under section 2(85) automatically receive the SMC relaxation?
No. Establish the distinct accounting-standard classification and applicable relaxation.
16. Can an AS 20 working be used as the full Ind AS 33 conclusion?
No. Apply the relevant reporting framework and its own requirements.

Conclusion
Treat EPS as a reconciliation of earnings and economic share participation across time. A dated denominator, precise bonus/rights factors and a documented anti-dilution test make the final number defensible and explainable.
