Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsOn March 3, 2020, the Company's board of directors authorized a share repurchase program of up to $100 million of the Company’s outstanding shares of common stock. Share repurchases may be made through open market purchases, block trades and/or privately negotiated transactions in compliance with Rule 10b-18 promulgated under the Securities Exchange Act of 1934, as amended, subject to market conditions, applicable legal requirements, and other relevant factors. Repurchases may also be made under Rule 10b5-1 plans, which permit shares of common stock to be repurchased through pre-determined criteria. The timing, volume and nature of the repurchases will be at the discretion of our management based on their evaluation of the capital needs of the Company, market conditions, applicable legal requirements and other factors. The program does not have an expiration date, and it may be suspended or discontinued at any time. As of the date of this filing, we used $26.0 million to repurchase 3.9 million shares of common stock at an average repurchase price of $6.56 per share under the repurchase program.
