Stock Repurchase Program
Our Board of Directors has approved a program for us to repurchase shares of our common stock. On September 17, 2018 and February 15, 2019, we announced that our Board of Directors approved expansions of our stock repurchase program totaling $24.0 billion. As of May 31, 2019, approximately $5.8 billion remained available for stock repurchases pursuant to our stock repurchase program.
Our stock repurchase authorization does not have an expiration date and the pace of our repurchase activity will depend on factors such as our working capital needs, our cash requirements for acquisitions and dividend payments, our debt repayment obligations or repurchases of our debt, our stock price, and economic and market conditions. Our stock repurchases may be effected from time to time through open market purchases or pursuant to a rule 10b5-1 plan. Our stock repurchase program may be accelerated, suspended, delayed or discontinued at any time.
The following table summarizes the stock repurchase activity for the three months ended May 31, 2019 and the approximate dollar value of shares that may yet be purchased pursuant to our stock repurchase program:
