Earnings Per Share

Basic income (loss) per share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the period. In computing dilutive income (loss) per share, basic income (loss) per share is adjusted for the assumed issuance of all potentially dilutive share-based awards, including stock options, restricted stock and warrants.

The following is a reconciliation of the weighted-average common shares outstanding used for the computation of basic and diluted net income (loss) per common share:



	Three Months Ended September 30, 2017	Three Months Ended September 30, 2016	Nine Months Ended September 30, 2017	Nine Months Ended September 30, 2016
Basic weighted-average common shares outstanding	49,676,923	49,567,735	49,852,337	49,385,733
Effect of dilutive options, performance stock units and restricted stock	492,511	60,065	282,254	—
Dilute weighted-average shares outstanding	50,169,434	49,627,800	50,134,591	49,385,733

Securities that could potentially be dilutive are excluded from the computation of diluted earnings per share when a loss from continuing operations exists or when the exercise price exceeds the average closing price of the Company's common stock during the period, because their inclusion would result in an anti-dilutive effect on per share amounts.

The following amounts were not included in the calculation of net income (loss) per diluted share because their effects were anti-dilutive:



(in thousands, except share data)	Three Months Ended September 30, 2017	Three Months Ended September 30, 2016	Nine Months Ended September 30, 2017	Nine Months Ended September 30, 2016
Stock-based compensation awards⁽¹⁾:
Stock options	577,500	584,375	577,500	584,375
Warrants:
Private placement warrants	6,160,000	6,160,000	6,160,000	6,160,000
Public warrants	9,823,072	9,823,072	9,823,072	9,823,072

(1)	SARs and Phantom Shares are payable in cash and will, therefore, have no impact on number of shares.

Warrants and options are considered anti-dilutive and excluded when the exercise price exceeds the average market value of the Company’s common stock price during the applicable period. Performance share units are considered anti-dilutive if the performance targets upon which the issuance of the shares is contingent have not been achieved and the respective performance period has not been completed as of the end of the current period.
