Stockholders' Equity	Stockholders' EquityThe Company's Board of Directors (the "Board") has approved a stock repurchase program (as updated from time to time, the "Program") authorizing the Company to repurchase its common stock from time to time until February 1, 2023. On July 27, 2021, the Board increased the aggregate size of the Program by $1 billion, to $5.1 billion, leaving the Company up to $1.6 billion available under the Program for future repurchases in shares of its common stock. Since the beginning of the Program through June 30, 2021, 16,184,095 shares have been repurchased for an aggregate purchase price of $3.5 billion. Any stock repurchases may be made at times and in such amounts as deemed appropriate. The timing and amount of stock repurchases, if any, will depend on a variety of factors including the stock price, market conditions, corporate and regulatory requirements, and any additional constraints related to material inside information the Company may possess. Any repurchases have been and are expected to be funded by a combination of available cash flow from the business, working capital and debt.
