In March 2020, we announced that we had temporarily suspended our share repurchases. As of March 31, 2022, we had $2,514 million remaining on our existing share repurchase authorization, which has no expiration date. In April 2022, we announced plans to resume our share repurchase program in the second quarter of 2022. Any future share repurchases will be made at the discretion of management and will depend on various factors including our share price, results of operations, financial condition and cash required for future business plans.
