_________ (1)Preferred stock dividends and other for the three and six months ended June 30, 2021 includes $13 million of issuance costs associated with the redemption of Series A preferred shares. See Note 5 for additional information. The effects from the assumed exercise of 4 million in stock options, restricted stock units and awards and performance stock units for both the three months and six months ended June 30, 2021 was not included in the above computations of diluted earnings per common share because such amounts would have had an antidilutive effect on earnings per common share. For the three and six months ended June 30, 2020, basic and diluted weighted-average common shares outstanding for earnings (loss) per common share are the same due to net losses.
