TREASURY STOCK

12 Months Ended

Dec. 31, 2021

At December 31, 2021 and 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 resumed repurchases in early 2022 under this authorization and, as of February 22, 2022, has repurchased approximately $500 million of the Company's common stock in the first quarter of 2022. The Company expects to complete repurchases under the remaining authorization within the next three years assuming the travel recovery continues and the Company is able to meet its minimum liquidity covenant under the revolving credit facility. See Note 12 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 years ended December 31, 2021, 2020, and 2019 (in millions, except for shares, which are reflected in thousands):

For the years ended December 31, 2021, 2020, and 2019, the Company remitted employee withholding taxes of $163 million, $141 million, and $151 million, respectively, to the tax authorities, which is different from the aggregate cost of the shares withheld for taxes for each year due to the timing in remitting the taxes. The cash remitted to the tax authorities is included in financing activities in the Consolidated Statements of Cash Flows.
