|Earnings Per Share [Abstract]|
|Earnings Per Share [Text Block]||
We computed basic earnings per share of common stock based on the weighted average number of shares of common stock outstanding during the period. We computed diluted earnings per share of common stock based on the weighted average number of shares of common stock outstanding plus potentially dilutive shares of common stock outstanding during the period.
Potentially dilutive shares of common stock from employee equity incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding stock options, the assumed vesting of outstanding restricted stock units (RSUs), and the assumed issuance of common stock under the stock purchase plan. Our convertible debentures due 2039 (2009 debentures) require settlement of the principal amount of the debt in cash upon conversion. Since the conversion premium is paid in cash or stock at our option, we determined the potentially dilutive shares of common stock by applying the treasury stock method.In all periods presented, securities which would have been anti-dilutive are insignificant and are excluded from the computation of diluted earnings per share. In all periods presented, we included our 2009 debentures in the calculation of diluted earnings per share of common stock because the average market price was above the conversion price. We could potentially exclude the 2009 debentures in the future if the average market price is below the conversion price.
