Earnings Per Share [Abstract]

Earnings Per Share

Note 4: Earnings Per Share

We calculate basic and diluted earnings per share (EPS) based on net income, which approximates income available to common shareholders for each period. Basic EPS is calculated using the two-class method, which includes the weighted-average number of common shares outstanding during the period and restricted stock units to be paid in stock that are deemed participating securities as they provide nonforfeitable rights to dividends. Diluted EPS considers the dilutive effect of all potential future common stock, including stock options, restricted stock units and the shares that could be issued upon the conversion of our convertible notes and upon the exercise of the related warrants. The call options purchased in connection with the issuance of the convertible notes and the capped call transaction entered into in 2011 are excluded from the calculation of diluted EPS as their impact is always anti-dilutive.

Upon conversion of our convertible notes, as described in Note 8 of our 2011 Form 10-K, the principal amount would be settled in cash, and the excess of the conversion value, as defined, over the principal amount may be settled in cash and/or shares of our common stock. Therefore, only the shares of our common stock potentially issuable with respect to the excess of the notes’ conversion value over the principal amount, if any, are considered as dilutive potential common shares for purposes of calculating diluted EPS.

The weighted-average shares outstanding for basic and diluted earnings per share are as follows:

	Three Months Ended
(In thousands)	March 31, 2012		April 2, 2011
Basic weighted-average shares outstanding		280,022		276,358
Dilutive effect of:
Convertible notes and warrants		13,902		41,504
Stock options and restricted stock units		708		1,257
Diluted weighted-average shares outstanding		294,632		319,119

Stock options to purchase 6 million and 4 million shares of common stock outstanding are excluded from our calculation of diluted weighted-average shares outstanding for the three months ended March 31, 2012 and April 2, 2011, respectively, as the exercise prices were greater than the average market price of our common stock for the periods. These securities could potentially dilute earnings per share in the future.
