Bonus Shares, Share Splits, and Share Consolidation

## Bonus Shares, Share Splits, and Share Consolidation

### Why Special Treatment?

Bonus shares (and splits/consolidations) involve no cash inflow — the company merely subdivides or consolidates existing equity. Earnings are unchanged but the share count changes, making EPS non-comparable across periods unless adjusted.

---

### AS 20 Rule

> Bonus shares are assumed to have been outstanding from the beginning of the earliest period presented, regardless of the actual date of issue.

This means:

  • Current year WANES: Include bonus shares for the full year (no time-weighting by issue date).
  • Prior year WANES: Restate prior year EPS to include the bonus shares — so comparatives remain meaningful.

The same rule applies identically to share splits and share consolidations (reverse splits).

### Two EPS Figures Reported for the Prior Year

---

### Comparison: Cash Issue vs. Bonus Issue

FeatureCash IssueBonus Issue / Split
Cash received?YesNo
Date of issue relevant for weighting?YesNo — always full year
Prior year EPS restated?NoYes

---

### If Bonus is Issued During the Year

For current year EPS, add the bonus shares to WANES from 1 Jan (start of the period), not from the actual issue date. The month of issue is irrelevant.

Worked example

### Example 1

Bonus Issue Affecting Current Year and Prior Year

YearEAFESHShares Before Bonus
20-1₹18,00,00020,00,000
20-2₹60,00,00020,00,000 (plus bonus issued during 20-2)

Bonus ratio: 2:1 (2 bonus shares for every 1 held) → Bonus shares = 40,00,000

---

EPS for 20-2 (Current Year)

Bonus shares assumed outstanding since 1 Jan 20-2 (full year):

WANES = 20,00,000 + 40,00,000 = 60,00,000 shares

EPS (20-2) = ₹60,00,000 / 60,00,000 = ₹1.00 per share

---

EPS for 20-1: Original (before bonus was known)

WANES = 20,00,000 shares

EPS (20-1) Original = ₹18,00,000 / 20,00,000 = ₹0.90 per share

---

EPS for 20-1: Restated (including bonus effect)

WANES restated = 20,00,000 + 40,00,000 = 60,00,000

EPS (20-1) Restated = ₹18,00,000 / 60,00,000 = ₹0.30 per share

---

Presentation in Financial Statements:

YearEPS (Original)EPS (Restated)
20-1₹0.90₹0.30
20-2₹1.00

Both figures are reported for the prior year. Comparing ₹0.30 (restated 20-1) with ₹1.00 (20-2) gives a meaningful growth picture.

⚠️ Common exam mistakes

  • Time-weighting bonus shares by the month they were actually issued — bonus shares always receive full-year weight from the start of the earliest period presented.
  • Not restating prior year EPS after a bonus issue — the comparative column becomes misleading without restatement.
  • Applying restatement only to the current year and not to the comparative prior year EPS.
  • Treating a share split or consolidation differently from a bonus issue — both receive identical treatment under AS 20.
  • Reporting only restated EPS and omitting the original prior year EPS — both must be disclosed.
Reference: Para 22–24 (Bonus shares, share splits, consolidations and restatement of prior period EPS) — AS 20 – Earnings Per Share (ICAI)
