Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On July 31, 2017, the Board of Directors approved the terms of a share repurchase program, under which the Company is authorized to repurchase up to $50.0 million of its common shares. The Company may repurchase shares through open market purchases, privately negotiated transactions, or otherwise in accordance with applicable federal securities laws, including through Rule 10b5-1 trading plans and under Rule 10b-18 of the Securities Exchange Act of 1934. Purchases will be made at times and prices considered appropriate by management. Any repurchased common stock will be available for use in connection with the Company's stock plans and for other corporate purposes. This authority will primarily be used to offset dilution caused by the issuance and exercise of stock options and other equity compensation programs. Based on the Company’s strong cash flow and balance sheet, this program will not impact our ability to execute our business plans, allocate capital for our capital investment projects or pursue other strategic initiatives. The Company expects to finance the share repurchase program through its operating cash flow and cash on hand. The share repurchase program may also be modified, suspended or discontinued at any time. The repurchase program has no time limit, however, the Company expects to complete this share repurchase program by December 31, 2017.
