Options to purchase approximately 1 million and 1 million shares of our common stock for the three months and 1 million and 1 million for the six months ended June 30, 2019 and 2018, respectively, were not included in the computation of diluted earnings per share because they were anti-dilutive.

On July 20, 2017 our Board of Directors approved a plan authorizing repurchases of up to $4.0 billion of our outstanding common stock in the open market at prevailing market prices or in privately negotiated transactions through December 31, 2020. This share repurchase authorization replaced any existing share repurchase authorization.
