Treasury Stock Method

What is the Treasury Stock Method?

Treasury Stock Method assumes that the options and stock warrants are exercised at the beginning of the year (or date of issue if later) and the proceeds from the exercise of options and warrants are used to purchase common stock for the treasury.


  • There is no adjustment to the net income in the numerator.
  • Upon exercise of the options or warrants, the company receives the following amount of proceeds: exercise price of the option x number of shares issued to holders of the options or stock warrants.
  • The company will then use the proceeds from the exercise of options and warrants to buy back common shares at the average market price for the year.
  • The net change in the number of shares outstanding is a number of shares issued to holders of the options or warrants less the number of shares acquired from the market.

Below are the 3 primary steps used for Treasury Stock Method

Stock Options - Net Effect
  • If the exercise price of the option or warrants is lower than the market price of the stock, dilution occurs.
  • If higher, the number of common shares is reduced, and the anti-dilutive effect occurs. In the latter case, exercise is not assumed.

Treasury Stock Method Example

During 2006, KK Enterprise reported a net income of $250,000 and had 100,000 shares of common stock. During 2006, KK Enterprise issued 1,000 shares of 10%, par $100 preferred stock outstanding. In addition, the company has 10,000 options with a strike price (X) of $2 and the current market price (CMP) of $2.5. Calculated the diluted EPS.

Assume tax rate – 40%

As you can see from above, for the year ended 2014, only 9.2 million were considered (instead of 24.946 million). Why?

The difference is 24.946 million – 9.2 million  = 15.746 million shares.
