Earnings Per Share [Abstract] |
Earnings Per Share | 10. EARNINGS PER SHARE Basic earnings per share (“EPS”) is calculated using the average number of shares of common stock outstanding during each period. For the calculation of diluted shares, we assume that restricted stock is outstanding on the date of vesting, and we assume the issuance of shares from the exercise of stock options using the treasury stock method. A reconciliation from basic to diluted shares follows: ﻿
﻿ |  |  |  |  |  |  |  |
﻿ |  | Three Months Ended September 30, |  | Nine Months Ended September 30,
﻿ |  | 2017 |  | 2016 |  | 2017 |  | 2016
﻿ |  | (in thousands)
﻿Basic weighted average shares outstanding |  | 58,817 |  | 58,708 |  | 58,682 |  | 58,600
﻿Effect of dilutive securities |  | — |  | — |  | 4 |  | —
﻿Diluted weighted average shares outstanding |  | 58,817 |  | 58,708 |  | 58,686 |  | 58,600
﻿Stock options and unvested restricted stock grants excluded from dilutive calculation because they would be anti-dilutive |  | 3,007 |  | 4,098 |  | 2,799 |  | 4,455
