Our stock repurchase programs are intended to programmatically offset the impact of dilution from our equity compensation programs and, subject to market conditions and other factors, to make opportunistic and programmatic repurchases of our common stock to reduce our outstanding share count. Any share repurchases under our stock repurchase programs may be made through open market transactions, block trades, privately negotiated transactions (including accelerated share repurchase transactions) or other means at times and in such amounts as management deems appropriate and will be funded from our working capital or other financing alternatives. Our stock repurchase programs may be limited or terminated at any time without prior notice. The timing and actual number of shares repurchased will depend on a variety of factors, including corporate and regulatory requirements, price and other market conditions and management’s determination as to the appropriate use of our cash.

In July 2017, our Board authorized a $3.0 billion stock repurchase program and in January 2018, our Board authorized an additional $6.0 billion stock repurchase program. These stock repurchase programs have no expiration from the date of authorization. The stock repurchase activity under our stock repurchase programs during the nine months ended September 30, 2018 is summarized as follows (in millions, except per share amounts):
