Earnings Per Share [Abstract] |
Net Income Per Share [Text Block] | Net Income Per Share Basic earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period plus dilutive securities. Dilutive securities include outstanding common stock options and unvested restricted stock units, less the number of shares that could have been purchased with the proceeds from the exercise of the options, using the treasury stock method. Options that are anti-dilutive, where their exercise price exceeds the average market price of the common stock are not included in the treasury stock method calculation. There were 6,239 anti-dilutive securities for the three months ended March 31, 2017 and no anti-dilutive securities for the three months ended March 31, 2016, respectively. The following table presents the calculation of net earnings per common share (“EPS”) — basic and diluted (in thousands, except per share data):
| Three months ended March 31,
| 2017 |  | 2016
Net income(1) | $ | 55,863 |  |  | $ | 18,160 |
Weighted-average number of common shares outstanding (for basic calculation) | 18,439 |  |  | 16,042 |
Dilutive securities(1) | 1,110 |  |  | 828 |
Weighted-average common and common equivalent shares outstanding (for diluted calculation)(1) | 19,549 |  |  | 16,870 |
EPS — basic | $ | 3.03 |  |  | $ | 1.13 |
EPS — diluted | $ | 2.86 |  |  | $ | 1.08 |
______________________________ (1) Net income, dilutive securities and weighted average common and common equivalent shares outstanding for the three months ended March 31, 2016 were adjusted from previously reported amounts due to the adoption of ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting in the second quarter of 2016 (see Note 1: Basis of Presentation).
