Income (Loss) Per Share |
Income (Loss) Per Share | Note 2 — Income (Loss) Per Share ​ Basic income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding during the period. Diluted income per share is calculated by dividing net income by the weighted average number of shares used to calculate basic income per share plus the weighted average number of common share equivalents outstanding during the period. The dilutive effect of outstanding options to purchase common stock and non-participating share-based awards is considered in diluted income per share by application of the treasury stock method. The dilutive effect of performance share units is included in diluted income per common share in the periods the performance targets have been achieved, or would have been achieved if the reporting date was the end of the contingency period. ​ The computations of basic and diluted income (loss) per share for the years ended December 31, 2020, 2019, and 2018 are as follows: ​
