Stockholders' Equity Note [Abstract] |
Shareholders’ equity | Shareholders’ equity During the nine months ended September 30, 2020, we declared cash dividends totaling $97.5 million and repurchased 2.8 million shares under our repurchase authorization for $95.7 million. For the nine months ended September 30, 2019, we declared cash dividends totaling $91.6 million and repurchased 7.7 million shares under our repurchase authorization for $244.4 million. In May 2019, our board of directors approved a $500.0 million increase in our share repurchase authorization. At September 30, 2020, we had remaining authorization to repurchase $429.9 million of common shares. Under our share-based compensation plans, we accept shares as payment under certain conditions related to stock option exercises and vesting of shares, generally related to the payment of minimum tax obligations. During the nine months ended September 30, 2020 and 2019, participants surrendered shares valued at $14.9 million and $10.7 million, respectively, under these plans. Such share transactions are excluded from the above noted share repurchase authorization.
