TREASURY STOCK (Notes)

6 Months Ended

Jun. 30, 2021

At June 30, 2021 and December 31, 2020, the Company had a total remaining authorization of $10.4 billion to repurchase its common stock under a program authorized by the Company's Board of Directors in 2019 to repurchase up to $15.0 billion of the Company's common stock. The Company has not repurchased any shares since March 2020 under this authorization and does not intend to initiate any repurchases under this authorization until it has better visibility into the shape and timing of a recovery from the COVID-19 pandemic. See Note 9 for a description of the impact of the 2020 credit facility amendment on the Company's ability to repurchase shares. Additionally, the Board of Directors has given the Company the general authorization to repurchase shares of its common stock withheld to satisfy employee withholding tax obligations related to stock-based compensation.

The following table summarizes the Company's stock repurchase activities during the three and six months ended June 30, 2021 and 2020 (in millions, except for shares, which are reflected in thousands):

For the six months ended June 30, 2021 and 2020, the Company remitted employee withholding taxes of $150 million and $132 million, respectively, to the tax authorities, which is different from the aggregate cost of the shares withheld for taxes for each period due to the timing in remitting the taxes. The cash remitted to the tax authorities is included in financing activities in the Unaudited Consolidated Statements of Cash Flows.
