Shareholders' Equity

Shareholders' Equity

During 2020, 2019, and 2018, we repurchased $500.0 million, $4.40 billion and $4.15 billion, respectively, of shares associated with our share repurchase programs. As of December 31, 2020, we had $1.00 billion remaining under our $8.00 billion share repurchase program that our board authorized in June 2018.

We have 5.0 million authorized shares of preferred stock. As of December 31, 2020 and 2019, no preferred stock was issued.

We have an employee benefit trust that held 50.0 million shares of our common stock at both December 31, 2020 and 2019, to provide a source of funds to assist us in meeting our obligations under various employee benefit plans. The cost basis of the shares held in the trust was $3.01 billion at both December 31, 2020 and 2019, and is shown as a reduction of shareholders’ equity. Any dividend transactions between us and the trust are eliminated. Stock held by the trust is not considered outstanding in the computation of EPS. The assets of the trust were not used to fund any of our obligations under these employee benefit plans during the years ended December 31, 2020, 2019, and 2018.
