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 six months ended June 30, 2017 and 2016, the Company repurchased no shares of common stock under the January 2015 authorization. As of June 30, 2017, there were 6,771,458 shares available for repurchase under the authorization.
