Shareholders' Equity
Shareholders’ equity

We reinstated our quarterly cash dividend in July 2013. During the three months ended March 31, 2014, we declared a cash dividend of $0.05 per common share paid in April 2014.

During the three months ended March 31, 2014, we repurchased 2.2 million shares under our repurchase authorization for a total of $44.6 million. Such repurchases are reflected as a reduction of common stock and retained earnings. At March 31, 2014, we had remaining authorization to repurchase $189.7 million of common shares.

Under our stock-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 three months ended March 31, 2014 and 2013, employees surrendered shares valued at $5.5 million and $6.4 million, respectively, under these plans. Such share transactions are excluded from the above noted stock repurchase authorization.
