# Treasury Stock Method

A method for calculating the effect of outstanding stock options and warrants on diluted EPS

## What is the Treasury Stock Method?

The treasury stock method is a way for companies to calculate how many additional shares may be generated from outstanding in-the-money warrants and options. These new additional shares can then be used in calculating the company’s diluted earnings per share (EPS).

The treasury stock method implies that the money obtained by the company from the exercising of an in-the-money option is used for stock repurchases. Repurchasing those shares turns them into treasury stock, hence the name.

Generally Accepted Accounting Principles (GAAP) mandates that companies must provide details on its diluted EPS. Therefore, this method is utilized to compute this figure for financial reporting.

EPS is diluted due to outstanding in-the-money options and warrants. These allow investors which own them to buy a number of common shares at a price below lower than the current market price.

### Treasury Stock Method Formula:

Additional shares outstanding = Shares from exercise – repurchased shares

Additional shares outstanding = n – (n x K / P)

Additional shares outstanding = n (1 – K/P)

Where;

N = shares from options or warrants that are exercised

K = Average exercise share price

P = Average share price for the period

### Implementing the Treasury Stock Method

The treasury stock method has certain assumptions:

1. The company repurchases common shares using an average price dictated by the market using the capital obtained when investors exercise their options
2. When exercising warrants and options, the exercise date assumed is the start of the reporting period.

### Example

For example, a company has an outstanding total of in-the-money options and warrants for 15,000 shares. The exercise price of each of these options is \$7. The average market price, however, for the reporting period is \$10. Assuming all the options and warrants outstanding are exercised, the company will generate 15,000 x \$7 = \$105,000 in proceeds. Using these proceeds, the company can buy \$105,000 / \$10 = 10,500 shares at the average market price. Thus, the net increase in shares outstanding is 15,000 – 10,500 = 4,500.

This can also be found by simply using the last formula provided above. The net increase in shares outstanding is 15,000 (1 – 7/10) = 4,500.

### Effect on Diluted EPS

The exercise of in-the-money options and warrants is the most dilutive of all potentially dilutive securities. As a summary, EPS is found by taking net income and dividing it by weighted average shares outstanding, or WASO.

Using the treasury stock method, there is no effect on net income, as all proceeds from the repurchase are assumed to be depleted in repurchasing treasury stock off the market. However, there is an effect on shares outstanding, or the WASO.

Since net income, the numerator, has a change of zero under the treasury stock method and the weighted average shares outstanding, the denominator, increases, there is a guaranteed decrease in the diluted EPS.
