Earnings Per Share [Abstract] |
Basic and Diluted Loss Per Share | Basic and Diluted Net Loss Per Share
Basic and diluted net loss per share were the same, as any additional common stock equivalents would be anti-dilutive. We excluded 2.6 million, 2.9 million and 1.8 million stock options from the calculation of diluted weighted-average net loss per share for the years ended December 31, 2017, 2016 and 2015, respectively, which would be anti-dilutive due to the net loss in those periods. In addition, we excluded 3.8 million, 4.9 million and 5.6 million RSUs from the calculation of diluted weighted-average net loss per share for the years ended December 31, 2017, 2016 and 2015, respectively, which would be anti-dilutive due to the net loss in those periods.
