Ind AS 33 Earnings Per Share — Basic vs Diluted EPS Explained
If you ever wondered why a company reports two EPS figures in its financial statements, Ind AS 33 is your answer. Understanding this standard is not just an exam requirement — it genuinely helps you read real annual reports. Let us walk through it together, the way I would explain it on a whiteboard in class.

Why Two EPS Numbers?
A company's profit belongs to its equity shareholders. But some instruments — convertible bonds, stock options, warrants — can become equity shares in the future. If they convert, the profit gets shared among more shareholders.
- Basic EPS tells you the earnings per share that currently exist.
- Diluted EPS tells you what EPS would look like if every possible conversion happened today.
Diluted EPS is always ≤ Basic EPS (unless the instrument is anti-dilutive, which we discuss below).

The Core Formula
Basic EPS
Basic EPS = Profit attributable to ordinary equity holders ──────────────────────────────────────────── Weighted Average Number of Equity Shares (WANES)
Two things to get right here:
Numerator — Start with net profit after tax, then deduct preference dividends (both declared dividends on non-cumulative preference shares and the year's accrual on cumulative preference shares). What remains belongs to ordinary shareholders.
Denominator — Shares are weighted by the fraction of the year they were outstanding. If 1,00,000 new shares were issued on 1 October, they are outstanding for 6 months (in a calendar-year company), so they contribute 50,000 to the weighted average.
Quick Logic Example — Basic EPS
Suppose:
- Profit after tax = ₹24,00,000
- Preference dividend for the year = ₹2,00,000
- Shares at start of year = 4,00,000
- Fresh issue of 1,20,000 shares on 1 July (halfway through the year)
Step 1 — Adjusted profit = 24,00,000 − 2,00,000 = ₹22,00,000
Step 2 — WANES:
- 4,00,000 × 12/12 = 4,00,000
- 1,20,000 × 6/12 = 60,000
- WANES = 4,60,000 shares
Step 3 — Basic EPS = 22,00,000 ÷ 4,60,000 = ₹4.78 per share (rounded)

Bonus Issue and Rights Issue — Adjust Retrospectively
When a company issues a bonus issue, no cash comes in. Those shares are treated as if they always existed. So you restate the denominator for all prior periods presented.
A rights issue has a below-market element (the bonus portion) and a market-price element. Ind AS 33 requires you to compute a theoretical ex-rights price and adjust accordingly — verify the exact mechanics in the latest ICAI study material.

Diluted EPS — Adding Potential Equity Shares
Potential equity shares are instruments that can convert into ordinary shares:
- Convertible debentures / bonds
- Convertible preference shares
- Employee stock options (ESOPs)
- Warrants
For diluted EPS you adjust both the numerator and the denominator.
Numerator Adjustment
Add back the after-tax cost that would have been saved if the instrument converted. For example, if convertible bonds carry interest at 10% on ₹10,00,000 and tax rate is 25%, you add back: 1,00,000 × (1 − 0.25) = ₹75,000.
Denominator Adjustment
Add the shares that would be issued on conversion.
Quick Logic Example — Diluted EPS
Continuing from above (Basic EPS = ₹4.78):
- The company also has 1,00,000 convertible debentures, each convertible into 1 equity share.
- Interest on debentures for the year = ₹80,000; tax rate = 25%.
Adjusted numerator = 22,00,000 + 80,000 × (1 − 0.25) = 22,00,000 + 60,000 = ₹22,60,000
Adjusted denominator = 4,60,000 + 1,00,000 = 5,60,000 shares
Diluted EPS = 22,60,000 ÷ 5,60,000 = ₹4.04 per share
Since ₹4.04 < ₹4.78, the instrument is dilutive — it must be included.

Anti-Dilutive Instruments — Ignore Them
If including a potential equity share increases EPS (rather than reducing it), it is anti-dilutive. Ind AS 33 says: exclude anti-dilutive instruments from the diluted EPS calculation. You may still disclose them, but they cannot improve the diluted figure.

Key Presentation Rules
- Both Basic and Diluted EPS must appear on the face of the Statement of Profit and Loss.
- Even if the figures are negative (a loss per share), both must still be shown.
- If a company has discontinued operations, it presents EPS separately for continuing and discontinued operations — verify exact disclosure requirements in the latest ICAI study material.

Common Exam Traps to Avoid
- Forgetting to deduct cumulative preference dividend even when it was not declared.
- Treating a bonus issue like a fresh issue (it has no weighting — it is fully retrospective).
- Including anti-dilutive instruments in the diluted EPS denominator.
- Using end-of-year shares instead of the weighted average for basic EPS.

FAQs
Q1. Can diluted EPS ever be higher than basic EPS? Normally no — conversion adds shares (increasing the denominator) more than it adds earnings. If an instrument appears to increase EPS, it is anti-dilutive and must be excluded. The result is that reported diluted EPS is always ≤ basic EPS.
Q2. How are ESOPs handled in diluted EPS? Options have no interest cost, so the numerator stays unchanged. For the denominator, you apply the treasury stock method: calculate how many shares could be bought back at fair market price with the option proceeds, then add only the net incremental shares. The precise formula and threshold — verify in the latest ICAI study material.
Q3. Is Ind AS 33 applicable to all companies? Ind AS 33 applies to companies whose shares are listed or are in the process of listing on a stock exchange. Unlisted entities are encouraged (but not required) to disclose EPS. Confirm current applicability thresholds in the latest ICAI study material / announcement.

Getting comfortable with Ind AS 33 is all about practising the denominator — the weighted average calculation trips most students up until they draw a simple timeline. Map out the share movements month by month, weight each tranche, and the rest follows logically.
