Ind AS 33 prescribes principles for the determination and presentation of earnings per share (EPS), one of the most widely used performance measures and a figure presented on the face of the statement of profit and loss. EPS reduces a company's profit to a per-share amount, improving comparison of performance between entities for the same period and between periods for the same entity. Because it is so heavily relied upon by investors, Ind AS 33 standardises exactly how it is calculated and presented. Its mechanics are closely aligned with AS 20, with differences flowing mainly from the Ind AS presentation framework.
Objective and scope
The objective is to prescribe principles for the determination and presentation of earnings per share, so as to improve performance comparisons between different entities in the same period and between different periods for the same entity. The standard applies to entities whose ordinary shares or potential ordinary shares are publicly traded (or in the process of issuing them), and to any entity that chooses to disclose EPS. Where both consolidated and separate financial statements are presented, the EPS disclosures are required only on the basis of the consolidated information.
Basic earnings per share
Basic EPS is calculated by dividing the profit or loss attributable to ordinary equity holders of the parent entity (the numerator) by the weighted average number of ordinary shares outstanding during the period (the denominator).
The numerator is the profit or loss from continuing operations attributable to the parent, and the profit or loss attributable to the parent, after deducting preference dividends (and any related tax) and any other items attributable to preference shareholders. Preference dividends are deducted because that portion of profit belongs to preference shareholders.
The denominator is the weighted average number of ordinary shares outstanding during the period — the number outstanding at the beginning, adjusted for shares issued or bought back during the period, weighted by the proportion of the period for which they were outstanding. Where the number of shares changes without a corresponding change in resources (for example, a bonus issue or share split), the weighted average is adjusted for all periods presented as if the event had occurred at the beginning of the earliest period, so EPS remains comparable.
Diluted earnings per share
Certain instruments — convertible bonds, convertible preference shares, options, and warrants — could result in additional ordinary shares being issued, diluting existing holders' EPS. Diluted EPS shows EPS after taking into account the effect of all dilutive potential ordinary shares, giving a picture of the maximum potential dilution.
Diluted EPS is calculated by adjusting the profit attributable to ordinary equity holders and the weighted average number of shares for the effects of all dilutive potential ordinary shares. The numerator is adjusted for the after-tax effect of dividends or interest recognised on the dilutive potential ordinary shares and any other consequential changes in income or expense; the denominator is increased by the weighted average number of additional ordinary shares that would have been outstanding on conversion of the dilutive potential ordinary shares. Only dilutive potential ordinary shares (those whose conversion would decrease EPS or increase loss per share) are included; anti-dilutive potential ordinary shares are ignored, because including them would misleadingly improve EPS.
Presentation — continuing and discontinued operations
Ind AS 33 requires an entity to present, on the face of the statement of profit and loss, basic and diluted EPS for profit or loss from continuing operations and for profit or loss attributable to the ordinary equity holders of the parent, with equal prominence, for all periods presented. Where the entity reports a discontinued operation, it also presents basic and diluted EPS for the discontinued operation (either on the face of the statement of profit and loss or in the notes). This continuing/discontinued split reflects the Ind AS presentation framework and is a point of difference from AS 20.
Disclosure
The entity discloses the amounts used as the numerators in calculating basic and diluted EPS and a reconciliation of those amounts to the profit or loss attributable to the parent for the period; the weighted average number of ordinary shares used as the denominators and a reconciliation of these denominators to each other; and instruments (including contingently issuable shares) that could potentially dilute basic EPS in the future but were not included because they were anti-dilutive in the periods presented.
A brief illustration
A company has profit attributable to ordinary equity holders of ₹45 lakh (after deducting ₹5 lakh preference dividends from a ₹50 lakh profit), and 9 lakh ordinary shares outstanding all year, giving basic EPS of ₹5. It also has convertible bonds that, if converted, would add 1 lakh shares and save ₹1 lakh after-tax interest. Testing dilution: diluted EPS would be (₹45 lakh + ₹1 lakh) ÷ (9 lakh + 1 lakh) = ₹4.60. Since ₹4.60 is below the basic ₹5, the bonds are dilutive and included, so diluted EPS of ₹4.60 is presented alongside basic EPS of ₹5. If the company had a discontinued operation, it would additionally present EPS figures for continuing operations and for the discontinued operation separately — a presentation AS 20 does not require in the same way.
How Ind AS 33 compares with AS 20
Ind AS 33 and AS 20 are closely aligned — the same definitions of basic and diluted EPS, the same use of weighted average shares, the same treatment of dilutive versus anti-dilutive potential ordinary shares, the same adjustment for bonus issues and share splits, and the same requirement to present both figures with equal prominence on the face of the statement of profit and loss. The main difference is presentation: Ind AS 33 requires EPS to be presented separately for profit or loss from continuing operations (and to present EPS for any discontinued operation), reflecting the Ind AS presentation framework, whereas AS 20 focuses on EPS for the net profit or loss without that continuing/discontinued split. Ind AS 33 also contains more detailed application guidance for complex instruments. For most entities, the EPS figures computed under the two standards are the same.
Common pitfalls
Recurring issues include failing to deduct preference dividends from the numerator; not time-weighting shares issued or bought back during the period; not adjusting prior-period EPS for bonus issues or share splits; including anti-dilutive potential ordinary shares in diluted EPS; and not presenting basic and diluted EPS with equal prominence, including for continuing operations and in loss-making periods.
Why this is cleaner on a unified system
Computing EPS reliably requires accurate data on profit (split between continuing and discontinued operations), preference dividends, and movements in share capital during the period — far easier when the equity records (share issues, buybacks, convertible instruments) and the ledger sit in one connected system. When profit and the weighted average share count are drawn from a single source of truth, calculating basic and diluted EPS and reconciling the numerators and denominators for disclosure is more straightforward than assembling the figures from separate registers and the accounts — especially where a company also administers equity instruments such as ESOPs, whose potential dilution feeds directly into diluted EPS.
