The cost method of recording treasury stock is the accounting approach in which a corporation records shares it buys back from shareholders at the amount it paid for them. The cost is debited to a Treasury Stock account, which is shown as a deduction from total stockholders' equity until the shares are reissued or retired. It is by far the most common method used by US companies.
Treasury stock means issued shares that the company has reacquired but not cancelled. The cost method is one of two methods allowed under US GAAP; the other is the par value method, sometimes called constructive retirement, which treats the repurchase as if the shares were retired. The cost method is simpler because it leaves the original common stock and paid-in capital accounts untouched at the time of purchase.
The cost method in plain terms
Imagine a club that sold membership cards and later buys some back from members who are leaving. The club could tear up the cards, or it could keep them in a drawer to sell to new members later. The cost method is the "keep them in a drawer" approach: the club simply notes what it paid for the cards it is holding.
Those cards in the drawer are not assets. A company cannot own a piece of itself in any meaningful sense, so the money paid is treated as a reduction of the owners' stake. When the shares are sold again, any difference between the resale price and what was paid goes straight to equity, never to profit.
Journal entries under the cost method
Suppose Brightline Inc. buys back 1,000 of its own $1 par shares at $30 each:
- Repurchase. Debit Treasury Stock $30,000; credit Cash $30,000. The par value and the original issue price are ignored.
- Reissue above cost. Brightline later sells 400 of the shares at $35. It debits Cash $14,000, credits Treasury Stock $12,000 (400 times $30) and credits Paid-in Capital from Treasury Stock $2,000.
- Reissue below cost. It then sells 300 shares at $26. It debits Cash $7,800, debits Paid-in Capital from Treasury Stock $1,200 and credits Treasury Stock $9,000. If that paid-in capital account had too small a balance, the rest of the shortfall would be debited to retained earnings.
After these entries, 300 shares remain in treasury at a cost of $9,000, and the Paid-in Capital from Treasury Stock account holds $800. No gain or loss appears on the income statement, because a company does not earn income by trading in its own shares.
If the company decides to retire treasury shares instead of reissuing them, it removes their par value from Common Stock, removes the related share of additional paid-in capital from the original issue, and charges any remaining difference to paid-in capital or retained earnings, crediting Treasury Stock for the cost.
Presentation and effects
On the balance sheet, treasury stock at cost is subtracted as a single line after paid-in capital and retained earnings. The statement of stockholders' equity shows purchases and reissues during the year. The number of treasury shares held is usually disclosed, because it explains the gap between shares issued and shares outstanding.
Treasury shares carry no vote and receive no dividends, and they are excluded from the weighted average shares used to calculate earnings per share. Because buybacks reduce both cash and equity, they raise ratios such as return on equity and can lift earnings per share even when total profit is unchanged. Many states limit repurchases so that they do not impair a company's legal capital, and some companies disclose a restriction on retained earnings equal to the cost of shares held. Since 2023, publicly traded US corporations have also been subject to a federal excise tax on net share repurchases.
Cost method compared with the par value method
Under the par value method, a repurchase removes the shares' par value and original paid-in capital as if they were retired, and the treasury stock account is carried at par. Reissues are then recorded like a new issue of stock. The par value method spreads the effect across several equity accounts at the time of purchase; the cost method waits until shares are reissued or retired. Both methods give the same total stockholders' equity, but the cost method is easier to apply and to explain, which is why most companies choose it.
