4. STOCKHOLDERS' EQUITY AND BENEFIT PLANS

Common Stock Repurchase Programs. Purchases of the Company's common stock are made from time to time, subject to market conditions and at prevailing market prices, through the open market. Repurchased shares of common stock are recorded at cost and become authorized but unissued shares which may be issued in the future for general corporate and other purposes. The Company may terminate or limit its stock repurchase program at any time. In the event the repurchased shares are cancelled, the Company accounts for retirements by allocating the repurchase price to common stock, additional paid-in capital and retained earnings. The repurchase price allocation is based upon the equity contribution associated with historical issuances. These repurchase programs were conducted pursuant to Rule 10b-18 of the Exchange Act. During the period from the announcement of the Company's $750 million buyback authorization in August 2010 until the end of the First Quarter, the Company has repurchased approximately $509.4 million of its common stock, representing approximately 6.8 million shares.

During the First Quarter, the Company effectively retired 6.8 million shares of common stock repurchased under its repurchase programs during the 2010, 2011 and 2012 fiscal years. The effective retirement of common stock repurchased decreased common stock by $68,000, additional paid in capital by $28.5 million retained earnings by $481.4 million and treasury stock by $510.0 million.

The following table reflects the Company's common stock repurchase activity for the periods indicated (in millions):

Stock-Based Compensation Plans. The Company accounts for stock-based compensation in accordance with the provisions of ASC 718, Compensation-Stock Compensation ("ASC 718"), using the Black-Scholes option pricing model to determine the fair value of stock options and stock appreciation rights at the date of grant. The Company's current stock-based compensation plans include: (i) stock options and restricted stock for its international employees, (ii) stock options and restricted stock units for its non-employee directors and (iii) stock appreciation rights, restricted stock and restricted stock units for its U.S.-based employees.
