Share Buyback Procedure

A buyback returns cash to shareholders by having the company purchase back its own shares, but the size of the buyback decides how much approval it actually needs, and how tight the conditions around it get.

Procedures under the Companies Act are periodically revised. This article is for general information and does not constitute legal advice.

Board-Approved vs Shareholder-Approved Buybacks

Under Section 68 of the Companies Act, a buyback of up to 10% of the total paid-up equity capital and free reserves can be approved by the board alone. Anything larger, up to the overall statutory ceiling, needs a special resolution passed by shareholders. Both routes are still subject to the same overall cap and post-buyback tests described below; the board/shareholder distinction only changes who has to approve it, not whether the underlying conditions apply.

The 25% Cap and the Debt-Equity Test

Total buybacks in a financial year, board-approved and shareholder-approved combined, can’t exceed 25% of the company’s paid-up capital and free reserves. After the buyback, the company’s debt (secured and unsecured) can’t exceed twice its paid-up capital and free reserves, a solvency safeguard meant to stop a buyback from being financed in a way that leaves the company dangerously leveraged.

The Cooling-Off Period

A gap of one year generally has to pass before a company can undertake another buyback, or issue the same kind of securities it just bought back, counted from the closure of the previous buyback. This is meant to stop buybacks being used as a repeated, routine tool to manage share price rather than the exceptional capital-return event it’s intended to be. The company’s tax obligations and the shareholder’s own tax treatment on the proceeds are covered separately in the Dividend and Buyback Taxation article on this site.

FAQs: Share Buyback Procedure

Can the board approve a buyback on its own without shareholder approval?

Yes, but only up to 10% of paid-up equity capital and free reserves; anything beyond that needs a shareholder special resolution.

Does the 25% cap apply per buyback, or across the whole year?

Across the whole financial year, combining board-approved and shareholder-approved buybacks together.

What’s the point of the post-buyback debt-equity test?

It’s a solvency safeguard, ensuring the company isn’t left dangerously over-leveraged after returning cash to shareholders.

Can a company do back-to-back buybacks within the same year?

Generally no, a one-year cooling-off period applies before the next buyback of the same kind of security.

Does this article cover how buyback proceeds are taxed for the shareholder?

No, that’s covered separately in the Dividend and Buyback Taxation article; this one covers the company-law procedure only.
