Earnings Per Share [Abstract] |
Basic and Diluted Loss Per Share | Basic and Diluted Net Loss Per Share Basic and diluted net loss attributable to SGC per share were the same, as any additional common stock equivalents would be anti-dilutive. We excluded 1 million, 2 million and 3 million stock options from the calculation of diluted weighted-average net loss attributable to SGC per share for the years ended December 31, 2019, 2018 and 2017, respectively, which would be anti-dilutive due to the net loss attributable to SGC in those periods. In addition, we excluded 3 million, 3 million and 4 million RSUs from the calculation of diluted weighted-average net loss attributable to SGC per share for the years ended December 31, 2019, 2018 and 2017, respectively, which would be anti-dilutive due to the net loss attributable to SGC in those periods.
