Limitations of treasury stock

*Treasury stock is not entitled to receive a

*Treasury stock has no voting rights *Total treasury stock can not exceed the maximum proportion of total capitalization specified by law in the relevant country When shares are repurchased, they may either be canceled or held for reissue. If not canceled, such shares are referred to as treasury shares. Technically, a repurchased share is a company's own share that has been bought back after having been issued and fully paid. The possession of treasury shares does not give the company the right to vote, to exercise preemptive rights as a shareholder, to receive cash dividends, or to receive assets on company liquidation. Treasury shares are essentially the same as unissued capital, which is not classified as an asset on the balance sheet, as an asset should have probable future economic benefits. Treasury shares simply reduce ordinary share capital.

, a company buying back its stock should have no effect on its price per share valuation. If the market fairly prices a company's shares at $50/share, and the company buys back 100 shares for $5,000, it now has $5,000 less cash but there are 100 fewer shares outstanding; the net effect should be that the underlying value of each share is unchanged. Additionally, buying back shares will improve price/earnings ratios due to the reduced number of shares (and unchanged earnings) and improve

ratios due to fewer shares outstanding (and unchanged earnings). If the market is not efficient, the company's shares may be underpriced. In that case a company can benefit its other shareholders by buying back shares. If a company's shares are overpriced, then a company is actually hurting its remaining shareholders by buying back stock.

Incentives

One other reason for a company to buy back its own stock is to reward holders of

stock options In finance, an option is a contract which conveys to its owner, the ''holder'', the right, but not the obligation, to buy or sell a specific quantity of an underlying asset or instrument at a specified strike price on or before a specified date ...

. Call option holders are hurt by dividend payments, since, typically, they are not eligible to receive them. A share buyback program ''may'' increase the value of remaining shares (if the buyback is executed when shares are under-priced); if so, call option holders benefit. A dividend payment short term ''always'' decreases the value of shares after the payment, so, for stocks with regularly scheduled dividends, on the day shares go ex-dividend, call option holders ''always'' lose whereas put option holders benefit. This does not apply to unscheduled (special) dividends since the strike prices of options are typically adjusted to reflect the amount of the special dividend. Finally, if the sellers into a corporate buyback are actually the call option holders themselves, they may directly benefit from temporary unrealistically favorable pricing.

After buyback

The company can either retire (cancel) the shares (however, retired shares are not listed as treasury stock on the company's financial statements) or hold the shares for later resale. Buying back stock reduces the number of outstanding shares. Accompanying the decrease in the number of shares outstanding is a reduction in company assets, in particular, cash assets, which are used to buy back shares.

to shareholders' equity. One way of accounting for treasury stock is with the cost method. In this method, the paid-in capital account is reduced in the balance sheet when the treasury stock is bought. When the treasury stock is sold back on the open market, the paid-in capital is either debited or credited if it is sold for less or more than the initial cost respectively. Another common way for accounting for treasury stock is the

method. In the par value method, when the stock is purchased back from the market, the books will reflect the action as a retirement of the shares.

In either method, any transaction involving treasury stock cannot increase the amount of
