6 Months Ended

Jun. 30, 2018

Our Board of Directors has approved a series of plans authorizing repurchases of our common stock in the open market at prevailing market prices or in privately negotiated transactions, the most current of which on July 20, 2017, authorized repurchases of up to $4.0 billion through December 31, 2020. This share repurchase authorization replaced any existing share repurchase authorization plan. Approximately $3.3 billion of plan capacity remained available for repurchases as of June 30, 2018.

The table below summarizes annual share repurchase activity under these plans (in millions, except per share amounts):
