Net (Loss) Income per Share Attributable to Common Stock |
Net (Loss) Income per Share Attributable to Common Stock | 13. Net (Loss) Income per Share Attributable to Common Stock Net loss per share attributable to common stock is calculated using the two-class method. The two-class method is an allocation method of calculating loss per share when a company’s capital structure includes participating securities that have rights to undistributed earnings. Historically, the Company’s employees and officers that held unvested restricted stock were entitled to dividends when the Company paid dividends (“participating”). The Company’s employees and officers that hold unvested restricted stock awarded during 2016 are not entitled to dividends when the Company pays dividends (“non-participating”). The Company’s basic net loss per share attributable to common stock is computed by reducing the Company’s net loss by the income allocable to unvested restricted stockholders that have a right to participate in earnings. The Company’s employees and officers that hold unvested restricted stock do not participate in losses because they are not contractually obligated to do so. The undistributed earnings are allocated based on the relative percentage of the weighted average unvested participating restricted stock awards. The basic net loss per share attributable to common stock is computed by dividing the net loss attributable to common stock by the weighted average shares outstanding. The weighted average shares outstanding for the year ended December 31, 2015 was calculated by totaling (i) the product of (x) the weighted shares of Legacy Dawson Common Stock outstanding at the beginning of the year multiplied by (y) the Exchange Ratio, plus (ii) the number of shares associated with awards of Legacy Dawson participating restricted stock and restricted stock units that vested in conjunction with the Merger, weighted as of February 11, 2015, plus (iii) the number of shares of Legacy TGC Common Stock outstanding immediately prior to the Merger, weighted to reflect that such shares were outstanding from February 11, 2015 until December 31, 2015. The weighted average number of shares outstanding for the three months ended December 31, 2014 and for the year ended September 30, 2014 were calculated as if the Merger had occurred at the beginning of the respective period, and the components of the weighted average shares calculation were multiplied by the Exchange Ratio. The Company’s diluted loss per share attributable to common stock is computed by adjusting basic loss per share attributable to common stock by income allocable to unvested participating restricted stock, if any, divided by weighted average diluted shares outstanding. A reconciliation of the loss per share attributable to common stock is as follows:

The Company had a net loss in the years ended December 31, 2016 and 2015, the three months ended December 31, 2014 and the year ended September 30, 2014. As a result, all stock options, restricted stock unit awards, and non-participating restricted stock awards were anti-dilutive and excluded from weighted average shares used in determining the diluted loss attributable to a share of common stock for the respective periods. The following weighted average numbers of stock options, restricted stock unit awards, and non-participating restricted stock awards have been excluded from the calculation of diluted loss per share attributable to common stock, as their effect would be anti-dilutive for the years ended December 31, 2016 and 2015, the three months ended December 31, 2014 and the year ended September 30, 2014:
|  | Year Ended December 31, |  | Three Months Ended December 31, |  | Year Ended September 30, |
|  |  | 2016 |  |  | 2015 |  |  | 2014 |  |  | 2014 |
Stock options |  |  | 411,763 |  |  | 425,981 |  |  | 160,434 |  |  | 162,107 |
Restricted stock unit awards |  |  | 268,461 |  |  | 126,596 |  |  | 66,405 |  |  | 33,373 |

Total |  |  | 756,527 |  |  | 552,577 |  |  | 226,839 |  |  | 195,480 |
The following shares of participating restricted stock awards were included in common stock outstanding as such shares have a nonforfeitable right to participate in any dividends that might be declared and have the right to vote:
|  | Year Ended December 31, |  | Three Months Ended December 31, |  | Year Ended September 30, |
|  |  | 2016 |  |  | 2015 |  |  | 2014 |  |  | 2014 |
