Earnings Per Share [Abstract] |
Basic and Diluted Loss Per Share | Basic and Diluted Net Loss Per ShareBasic and diluted net loss attributable to SGC per share were the same, as any additional common stock equivalents would be anti-dilutive. We excluded 2 million, 1 million and 2 million stock options from the calculation of diluted weighted-average net loss attributable to SGC per share for the years ended December 31, 2020, 2019 and 2018, respectively, which would be anti-dilutive due to the net loss attributable to SGC in those periods. In addition, we excluded 3 million RSUs from the calculation of diluted weighted-average net loss attributable to SGC per share for each of the years ended December 31, 2020, 2019 and 2018, which would be anti-dilutive due to the net loss attributable to SGC in those periods.
