In January 2015, the Board of Directors approved a standing share repurchase authorization, whereby the Company may repurchase up to 15,000,000 shares of its common stock over the following three years. This plan replaced all previously authorized repurchase programs. During the three months ended March 31, 2017 and 2016, the Company repurchased no shares of common stock under the January 2015 authorization. As of March 31, 2017, there were 6,771,458 shares available for repurchase under the authorization.
