Stockholders' Equity Note [Abstract] |
Stockholders' Equity Note Disclosure [Text Block] | Shareholders’ Equity Preferred Stock We have authorized the issuance of 10 million shares of preferred stock with no par value. In the event of a liquidation, dissolution, or winding up of the affairs of the corporation, whether voluntary or involuntary, the holders of any outstanding preferred stock will be entitled to be paid a preferential amount per share to be determined by our Board of Directors prior to any payment to holders of common stock. There was no preferred stock issued or outstanding at December 31, 2016, 2015, and 2014. Stock Repurchase Plan On February 19, 2015, our Board authorized a new repurchase program of up to $50 million of our common stock over a 12-month period, beginning February 19, 2015. From February 19, 2015 through December 31, 2015, we repurchased 743,444 shares of our common stock, totaling $25.0 million. This program expired on February 19, 2016 with no share repurchases made subsequent to December 31, 2015.
