Earnings Per Share [Abstract] |
Earnings Per Share | Earnings Per Share The following table sets forth the computation of basic and diluted earnings per share (in thousands, except per share amounts):
| Three months ended |  | Nine months ended
| September 30, 2018 |  | September 24, 2017 |  | September 30, 2018 |  | September 24, 2017
Numerator: |  |  |  |  |  |  |
Net income used in computing basic and diluted earnings per share | $ | 113,855 |  |  | $ | 68,209 |  |  | $ | 530,956 |  |  | $ | 513,445 |
Denominator: |  |  |  |  |  |  |
Denominator for basic earnings per share - weighted-average common shares | 165,927 |  |  | 169,850 |  |  | 166,885 |  |  | 173,362 |
Effect of dilutive securities - employee stock compensation plan | 737 |  |  | 838 |  |  | 796 |  |  | 941 |
Denominator for diluted earnings per share - adjusted weighted-average shares outstanding | 166,664 |  |  | 170,688 |  |  | 167,681 |  |  | 174,303 |
Earnings per common share: |  |  |  |  |  |  |
Basic | $ | 0.69 |  |  | $ | 0.40 |  |  | $ | 3.18 |  |  | $ | 2.96 |
Diluted | $ | 0.68 |  |  | $ | 0.40 |  |  | $ | 3.17 |  |  | $ | 2.95 |
Outstanding options to purchase 0.8 million and 0.9 million shares of common stock for the three months ended September 30, 2018 and September 24, 2017, respectively, and 1.1 million and 0.8 million shares of common stock for the nine months ended September 30, 2018 and September 24, 2017, respectively, were not included in the Company’s computation of dilutive securities because the exercise price was greater than the market price, and therefore, the effect would have been anti-dilutive. The Company has a share-based compensation plan under which employees may be granted share-based awards including restricted stock units (RSUs). Non-forfeitable dividend equivalents are paid on unvested RSUs. As such, RSUs are considered participating securities under the two-class method of calculating earnings per share as described in ASC Topic 260, “Earnings per Share.” The two-class method of calculating earnings per share did not have a material impact on the Company’s earnings per share calculation for the three and nine month periods ended September 30, 2018 and September 24, 2017.
