At December 31, 2020, the Company had a total remaining authorization of $10.4 billion to repurchase its 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.

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 cash remitted to the tax authorities is included in financing activities in the Consolidated Statements of Cash Flows.
