In equity markets, companies often take corporate actions to make their shares more accessible and liquid without altering the underlying value of the business. Two commonly misunderstood actions are stock splits and bonus shares. Both increase the number of shares held by investors and reduce share price, but the mechanics, accounting treatment, and tax implications, especially in Pakistan, are materially different.
What Is a Stock Split?
A stock split occurs when a company divides each existing share into multiple shares in a fixed ratio, such as 2-for-1 or 5-for-1. A stock split does not change the company's market capitalization or the investor's total investment value.
Example: an investor owns 100 shares priced at PKR 1,000 each (total value PKR 100,000). After a 5-for-1 split: 500 shares at PKR 200 each, still PKR 100,000 total. The reduction in price is purely mathematical and represents no loss in wealth, since the company's market capitalization and the shareholder's proportional ownership remain unchanged.
Companies typically issue stock splits to reduce the per-share price and improve affordability, increase the number of shares available, and enhance liquidity. United Bank Limited (UBL) is a useful Pakistani example: its 2-for-1 split roughly doubled its outstanding shares from around 1.2 billion to approximately 2.5 billion.
What Are Bonus Shares?
Bonus shares are additional shares issued to existing shareholders free of cost, based on a specific percentage (e.g. 20%, 50%, or even 800%). Unlike stock splits, bonus shares are issued out of a company's reserves, such as retained earnings.
Example: an investor holds 1,000 shares at PKR 120 each (PKR 120,000 total). A 20% bonus issue adds 200 shares (1,200 total), and the adjusted price becomes 120 ÷ 1.20 = PKR 100, total value unchanged at PKR 120,000. Mari Energies' 800% bonus issue in 2014, eight bonus shares for every one held, increased shares ninefold and reduced the share price from around PKR 3,600 to approximately PKR 400, noticeably improving liquidity and trading activity.
Key Difference: Tax Treatment in Pakistan
In Pakistan, no tax applies to stock splits, since shares are merely subdivided, there's no concept of additional income. Bonus shares, however, are treated by the government as additional income even though the investor's overall value doesn't increase, so a withholding tax (currently 15%) applies.
Example: you own 100 shares at PKR 520 each (PKR 52,000). After a stock split, 200 shares at PKR 260, still PKR 52,000, no tax. With bonus shares, a 15% tax on the additional shares means you effectively receive 85 extra shares instead of 100, at PKR 260, that's 260 × 185 = PKR 48,100, a real reduction in value.
This tax liability has made stock splits more common in Pakistan while bonus share issuance has declined. Mari Energies and Fast Cables were likely among the last to issue bonus shares, while Lucky Cement (5-for-1), Systems Limited (5-for-1), Arif Habib Corporation (10-for-1), and UBL (2-for-1) have recently issued stock splits instead.
Final Perspective
While bonus shares and stock splits may appear similar on the surface, they differ in source, accounting treatment, and taxation. Stock splits are simpler, tax-neutral, and purely structural, whereas bonus shares involve reserves and attract tax in Pakistan. Understanding these distinctions can help you make better-informed investment decisions.
