Income (Loss) Per Common Share |
Income (Loss) Per Common Share | Note 2 — Income (Loss) Per Common Share Basic income (loss) per common share is calculated by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted income per common share is calculated by dividing net income available to common stockholders by using the weighted average number of common shares and common share equivalents outstanding during the period. The computations of basic and diluted income (loss) per common share are as follows:
|  | Year ended December 31, |
|  | 2014 |  | 2013 |  | 2012 |
|  | (in thousands, except per share amounts) |
Net income (loss) |  | $ | (66,940 | ) | $ | (42,263 | ) | $ | 30,928 |
Net income (loss) per common share: |  |  |  |  |  |  |
Basic |  | $ | (1.70 | ) | $ | (1.09 | ) | $ | 0.80 |
Diluted |  | $ | (1.70 | ) | $ | (1.09 | ) | $ | 0.79 |
Basic weighted average shares outstanding |  | 39,350 |  | 38,807 |  | 38,477 |
Effect of potentially dilutive share-based awards |  | — |  | — |  | 574 |
Diluted weighted average shares outstanding |  | 39,350 |  | 38,807 |  | 39,051 |
For the year ended December 31, 2014 and 2013, 0.7 million and 0.6 million common equivalent shares, respectively, were excluded from the computation of diluted net loss per share as their effect would be anti-dilutive since the Company incurred a net loss. The dilutive effect of outstanding options and restricted stock units is reflected in diluted income per common share by application of the treasury stock method. For the years ended December 31, 2014, 2013, and 2012, respectively, approximately 1.6 million, 1.3 million and 1.3 million potentially dilutive securities underlying restricted stock awards, restricted stock units, and options to purchase common stock were excluded from the calculation since they would have had an antidilutive effect on diluted income per common share.
