Investment In ValveXchange [Abstract]
Investment In ValveXchange	8. Investment in ValveXchange Preferred Stock Investment In July 2011 the Company purchased shares of series A preferred stock of ValveXchange for approximately $3.5 million. ValveXchange was a private medical device company that was spun off from Cleveland Clinic to develop a lifetime heart valve replacement technology platform featuring exchangeable bioprosthetic leaflets. As ValveXchange’s stock was not actively traded on any public stock exchange, and as the Company’s investment was in preferred stock, the Company initially accounted for this investment using the cost method as a long-term asset, investment in equity securities, on the Company’s Consolidated Balance Sheet. The Company determined that its investment in ValveXchange was fully impaired as of December 31, 2013, and the impairment was other than temporary. As of December 31, 2016 and 2015 the carrying value of the Company’s investment in ValveXchange preferred stock was zero. Loan Agreement In July 2011 the Company entered into an agreement with ValveXchange, as amended, to make available to ValveXchange up to $2.0 million in debt financing through a revolving credit facility (the “Loan”). The Loan included various affirmative and negative covenants, including financial covenant requirements, and would have expired on July 30, 2018, unless terminated earlier. Amounts under the Loan earned interest at an 8% annual rate and were secured by substantially all of the tangible and intangible assets of ValveXchange. The Company advanced $2.0 million to ValveXchange under this loan in 2012. During the quarter ended December 31, 2014 CryoLife became aware of various factors, including ValveXchange’s inability to secure additional funding, its lack of capital to continue basic operations, and the likelihood of impending default on the Loan. In December 2014 CryoLife notified ValveXchange that it was in breach of the Loan, and in January 2015, after ValveXchange failed to cure this breach, CryoLife accelerated the amounts due under the Loan. In January 2015 ValveXchange informed CryoLife management of its intent to file for bankruptcy, which created substantial uncertainty regarding the disposition of CryoLife’s claim for amounts it is owed under the Loan. Given these circumstances, CryoLife believed that its Loan became fully impaired in the fourth quarter of 2014. As a result, during the three months ended December 31, 2014 the Company recorded other non-operating expense of $2.0 million to write-down its long-term note receivable from ValveXchange. ValveXchange was dissolved in June 2015. The net carrying value of the long-term note receivable was zero as of December 31, 2016 and 2015.
