Subsequent Events [Abstract] |
Subsequent Events [Text Block] | Subsequent Events On October 2, 2018 we used $5.0 billion of net proceeds received from Nestlé to enter into an accelerated share repurchase program with third-party financial institutions. As a result, 72.0 million shares of our common stock have been retired. Final settlement is expected to be completed as early as February 2019 and no later than March 2019. Refer to Note 15, Commitments and Contingencies for further discussion. On October 24, 2018, we amended and restated our $1.0 billion unsecured 364-Day credit facility to extend the term, which is now set to mature on October 23, 2019.
