Share Repurchase Program | Share Repurchase Program In February 2018, our Board of Directors (the "Board") authorized a new share repurchase program to repurchase from time to time up to $300.0, excluding fees, of our common stock, which was in addition to the remaining amount available to be repurchased from the $300.0 authorization made by the Board in February 2017. We may effect such repurchases through open market purchases, trading plans established in accordance with SEC rules, derivative transactions or other means. The timing and amount of repurchases in future periods will depend on market conditions and other funding requirements. The following table presents our share repurchase activity under our share repurchase programs for the nine months ended September 30, 2018 and 2017.
