Earnings Per Share

Basic earnings per share for the three and nine months ended September 28, 2013 and September 29, 2012 was computed by dividing earnings available to common shareholders for these periods by the weighted average number of common shares outstanding in the respective periods adjusted for contingently issuable shares. The weighted average number of common shares outstanding for the three and nine months ended September 28, 2013 and September 29, 2012 have been adjusted to include common stock equivalents for the purpose of calculating diluted earnings per share for these periods.

Options to purchase 2,652,660 shares and 4,667,739 shares were outstanding in each of the three months ended September 28, 2013 and September 29, 2012, respectively, but were not included in computing diluted earnings per share because their inclusion would have been anti-dilutive. Basic weighted average shares outstanding for the three and nine months ended September 28, 2013 and September 29, 2012 excluded the weighted average impact of 1,107,313 and 941,873 shares, respectively, of non-vested restricted stock awards. Options to purchase 2,363,878 shares and 4,590,418 shares were outstanding in each of the nine months ended September 28, 2013 and September 29, 2012, respectively, but were not included in computing diluted earnings per share because their inclusion would have been anti-dilutive.

The following table illustrates the reconciliation of the numerator and denominator in the computations of the basic and diluted earnings per share:

Warrants

Separately and concurrently with the pricing of our 2013 Notes in 2006, we issued warrants for approximately 7.2 million shares of common stock. The warrants give the holders the right to receive, for no additional consideration, cash or shares (at the Company's option) with a value equal to the appreciation in the price of the Company's shares above $59.93. The warrants expire over 90 equal installments between September 13, 2013 and January 22, 2014. As of September 28, 2013, approximately 6.3 million are outstanding.
