What it means
When a company buys back its own shares, it pays out cash and receives shares that go into a treasury account. It can hold them indefinitely, reissue them later for employee share schemes or an acquisition, or formally cancel them, and each route has different accounting consequences.
The most common accounting approach is the cost method, where the full amount paid is recorded as a single negative line within equity. Because it reduces equity, a large buyback can noticeably increase reported gearing and return on equity without anything changing in the operating business.
Companies buy back shares for several reasons. Management may believe the shares are undervalued, may want to return surplus cash more flexibly than through a dividend, or may need shares to satisfy employee option exercises without issuing new ones that dilute existing holders.
The mechanical effect that gets the most attention is earnings per share. Reducing the number of shares outstanding raises earnings per share even when total profit is flat, which is why investors look carefully at whether a buyback reflects genuine surplus cash or is being used to flatter a per share metric.
The nuance is that a buyback is a use of capital like any other, and it should be judged against the alternatives. Cash spent buying shares at a high price is cash unavailable for equipment, acquisitions or debt repayment, and companies that borrow to buy back shares are increasing financial leverage in exchange for a short term optical gain.
In practice
Real-world examples
Example 1
A software company runs a share option scheme for 900 employees and buys back shares each quarter rather than issuing new ones. The treasury shares are reissued as options are exercised, so existing shareholders avoid dilution and the share count stays broadly stable.
Example 2
A consumer goods group sells a division for $600,000,000 and decides that half the proceeds should return to shareholders. It chooses a buyback over a special dividend because the shares are trading below the board's own valuation and because a buyback creates no expectation of repetition.
Example 3
An analyst reviewing a manufacturer notices earnings per share grew 8% while net income grew only 2%. Tracing the difference to a buyback funded by new borrowing, the analyst downgrades the quality of the earnings growth in the research note.
Think of it
Treasury stock is shares the company bought back-reacquired shares.
Formula
Calculation
Cost of treasury stock = number of shares repurchased x price paid per share
Shares outstanding = shares issued - treasury shares
A listed company has 10,000,000 shares issued and buys back 200,000 of them at $45 per share. The cost is 200,000 x $45 = $9,000,000, which is deducted from shareholders' equity as treasury stock, and shares outstanding fall to 10,000,000 - 200,000 = 9,800,000.
If net income for the year is $24,500,000, earnings per share before the buyback would have been $24,500,000 / 10,000,000 = $2.45. After the buyback it is $24,500,000 / 9,800,000 = $2.50, an increase of 2.04% produced entirely by the smaller share count rather than by any improvement in trading.Case study
Seen in the real world
The following is an illustrative, entirely fictional case. Coppermill Retail Group, an invented chain of homeware stores, generated strong cash flow and announced a $9,000,000 buyback of 200,000 shares at $45 to signal confidence after a weak trading update. Earnings per share duly rose from $2.45 to $2.50 and the announcement was well received.
Eighteen months later the same fictional company needed capital to refit thirty stores and found it had no headroom. It had spent the surplus cash on shares now trading at $31, so the buyback had destroyed roughly $2,800,000 of value on paper and left the refurbishment to be funded with expensive short term debt.
The board of the fictional group adopted a simple rule afterwards. Buybacks would only be approved from cash left over after the approved capital plan, and only when the shares traded below the internal valuation range, which converted the buyback from a signalling device into a capital allocation decision.
Watch out
Common mistakes
- Recording treasury stock as an asset, when it is always a deduction from shareholders' equity because a company cannot hold value in itself.
- Treating a rise in earnings per share after a buyback as evidence of better performance, when the profit figure may not have moved at all.
- Including treasury shares in the share count used for earnings per share or for dividend calculations, which understates both figures.
Questions
People also ask
Do treasury shares receive dividends or carry votes?
No, they are dormant while held by the company, which is why they are excluded from shares outstanding.
What is the difference between a buyback and cancelling shares?
A buyback puts the shares into treasury where they can be reissued later, while cancellation removes them permanently and reduces the issued share capital.
Is a buyback always better than a dividend?
Not always, since a buyback is discretionary and flexible but only creates value when the shares are bought below their intrinsic worth.
