Share Repurchase Programs [Abstract]
SHARE REPURCHASE PROGRAMS	SHARE REPURCHASE PROGRAMS In December 2019, our Board of Directors authorized a share repurchase program intended to mitigate the dilutive impact of shares issued under our employee stock plans (the 2019 program). Under the 2019 program, we are authorized to repurchase up to 1.5 million shares of common stock, the sum of which will not exceed the number of shares issued to employees under our employee stock plans from December 1, 2019 to December 11, 2021. Share repurchases of common stock are made periodically in open-market transactions and are subject to market conditions, legal requirements, and other factors. We may establish prearranged written plans under Rule 10b5-1 of the Securities Exchange Act of 1934 as part of the 2019 program, which allow for share repurchases during our quarterly blackout periods as set forth in the trading plan. In the second quarter of 2020, we decided to temporarily suspend the 2019 share repurchase program due to the impact of COVID-19; however, we recommenced the program in the fourth quarter of 2020. In 2020, we repurchased 0.6 million shares for $29 million under the 2019 program. During 2019 and 2018, we repurchased 0.5 million and 0.4 million shares for $28 million and $31 million, respectively, under previous share repurchase programs.
