Share Repurchase Program [Abstract]

Share Repurchase Program

16.       Share Repurchase Program

On August 11, 2011, the Company's board of directors approved a share repurchase program that authorizes the Company to purchase up to $100.0 million in the aggregate of the Company's common stock.  Purchases may be made from time to time using a variety of methods, which may include open market purchases, privately negotiated transactions or block trades, or by any combination of these methods, in accordance with applicable insider trading and other securities laws and regulations. The size, scope and timing of any purchases will be based on business, market and other conditions and factors, including price, regulatory and contractual requirements or consents, and capital availability. The repurchase program does not obligate the Company to acquire any particular amount of common stock and the program may be suspended, modified or discontinued at any time at the Company's discretion without prior notice. Shares of stock repurchased under the program will be held as treasury shares.

No shares were purchased pursuant to this authorization during the years ended December 31, 2014, 2013 and 2012. As of December 31, 2014, approximately $82.4 million remains available under this share repurchase authorization.
