Sales Of Business Components	5. Sales of Business Components Acquisition and Divestiture of HeRO Graft Product Line On May 16, 2012 CryoLife completed its acquisition of Hemosphere, a privately held company, and its Hemodialysis Reliable Outflow Graft (“HeRO® Graft”) product line for a total purchase price of approximately $22.0 million, net of $3.2 million cash acquired. CryoLife used cash on hand to fund the transaction and operated Hemosphere as a wholly owned subsidiary until December 31, 2014, when it was merged into the CryoLife, Inc. parent entity. The HeRO Graft is a proprietary graft-based solution for ESRD hemodialysis patients with limited access options and central venous obstruction. As of the acquisition date, CryoLife recorded a contingent consideration liability of $1.8 million in long-term liabilities on its Consolidated Balance Sheet, representing the estimated fair value of the contingent consideration expected to be paid to the former shareholders of Hemosphere upon the achievement of certain revenue-based milestones. The acquisition agreement provides for a maximum of $4.5 million in future consideration payments through December 2015 based on specified sales targets. The fair value of the contingent consideration liability was estimated by discounting to present value the contingent payments expected to be made based on a probability-weighted scenario approach. The Company applied a risk-based estimate of the probability of achieving each scenario and then applied a cost of debt based discount rate. This fair value measurement was based on unobservable inputs, including management estimates and assumptions about future revenues, and was, therefore, classified as Level 3 within the fair value hierarchy presented in Note 2. The Company remeasured this liability at each reporting date and recorded changes in the fair value of the contingent consideration in other (income) expense on the Company’s Consolidated Statements of Operations and Comprehensive Income. Increases or decreases in the fair value of the contingent consideration liability can result from changes in discount periods and rates, as well as changes in the timing and amount of Company revenue estimates. As of December 31, 2014 the Company reviewed the full year revenue performance of Hemosphere for 2014 and 2013, and reviewed its 2015 annual budgets, which were updated in the fourth quarter of 2014. As a result of this review, as of December 31, 2014 the Company believed that achievement of the minimum revenue target to trigger payment was remote, and, therefore, estimated the fair value of the contingent consideration to be zero. The Company recorded gains of zero for the years ended December 31, 2016 and 2015 and $1.9 million during the year ended December 31, 2014, on the remeasurement of the contingent consideration liability. The balance of the contingent consideration liability was zero as of December 31, 2016 and 2015. On February 3, 2016 the Company sold its HeRO Graft product line to Merit Medical Systems, Inc. (“Merit”) for $18.5 million in cash (“HeRO Sale”), of which $17.8 million had been received by December 31, 2016. The remaining $740,000 was received in the first quarter of 2017. Under terms of the agreement, Merit acquired the HeRO Graft product line, including worldwide marketing rights, customer relationships, intellectual property, inventory, and certain property and equipment. The Company continued to manufacture the HeRO Graft under a transition supply agreement until the sales transfer to Merit was completed in the second quarter of 2016. The HeRO Graft product line was included as part of the Company’s Medical Devices segment. The Company recorded a pre-tax gain of approximately $8.8 million on the HeRO Sale. ProCol Distribution Agreement and Divestiture of the ProCol Product Line In 2014 CryoLife acquired the exclusive worldwide distribution rights to ProCol® Vascular Bioprosthesis (“ProCol”) from Hancock Jaffe Laboratories, Inc. (“Hancock Jaffe”). In accordance with the terms of the agreement with Hancock Jaffe, CryoLife made payments to Hancock Jaffe of $1.7 million during 2014 and $576,000 in January 2015. In exchange for these payments, CryoLife obtained the right to receive a designated amount of ProCol inventory for resale, portions of which the Company received in 2014, 2015, and 2016. CryoLife made additional payments of $1.2 million in the aggregate during 2015 and the first quarter of 2016. As of March 18, 2016 CryoLife had made a total of $3.4 million in payments to Hancock Jaffe and had received $1.7 million in inventory. The remaining $1.7 million in prepayments were settled as part of the ProCol Sale, described below. On March 18, 2016 the Company sold its ProCol® Vascular Bioprosthesis (“ProCol”) distribution rights and purchase option to LeMaitre Vascular, Inc. (“LeMaitre”) for $2.0 million in cash (“ProCol Sale”), all of which was received by March 31, 2016. Under terms of the agreement, LeMaitre acquired the ProCol related assets, including inventory, customer lists, related marketing assets, and the Company’s purchase option to acquire ProCol. LeMaitre exercised the option to acquire ProCol from Hancock Jaffe Laboratories. The ProCol product was included as part of the Company’s Medical Devices segment. The Company recorded a pre-tax loss of approximately $845,000 on the ProCol Sale. Disclosure of the HeRO Sale and the ProCol Sale Financial Accounting Standards Board (“FASB”) ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, defines the criteria for reporting discontinued operations and requires additional disclosures about discontinued operations. The standard requires that an entity report as a discontinued operation only a disposal that represents a strategic shift in operations that has a major effect on the Company’s operations and financial results. In the first quarter of 2016 the Company completed the HeRO Sale and the ProCol Sale. The Company received cash for these transactions and recorded the results of these sales in March 2016. Therefore, as of March 31, 2016 both transactions met the disposed of by sale criteria under discontinued operations. The Company evaluated the impact of the HeRO Sale and the ProCol Sale on the Company’s business to determine whether these disposals represent a strategic shift that has, or will have, a major effect on the Company’s financial position, results of operations, or cash flows. As the HeRO Graft and ProCol product lines combined represented less than 10% of total Company revenues for the year ended December 31, 2015 and the Company’s total assets as of December 31, 2015, the Company believes that these transactions did not have a major effect on the Company’s operations and financial condition, either individually or in the aggregate, and therefore the Company did not disclose these transactions as discontinued operations. The combined net gain from the HeRO Sale and ProCol Sale was therefore reported as gain from sale of business components on the Company’s Summary Consolidated Statements of Operations and Comprehensive Income.

Acquisition and Divestiture of HeRO Graft Product Line

ProCol Distribution Agreement and Divestiture of the ProCol Product Line

In 2014 CryoLife acquired the exclusive worldwide distribution rights to ProCol® Vascular Bioprosthesis (“ProCol”) from Hancock Jaffe Laboratories, Inc. (“Hancock Jaffe”). In accordance with the terms of the agreement with Hancock Jaffe, CryoLife made payments to Hancock Jaffe of $1.7 million during 2014 and $576,000 in January 2015. In exchange for these payments, CryoLife obtained the right to receive a designated amount of ProCol inventory for resale, portions of which the Company received in 2014, 2015, and 2016.

The remaining $1.7 million in prepayments were settled as part of the ProCol Sale, described below.

On March 18, 2016 the Company sold its ProCol® Vascular Bioprosthesis (“ProCol”) distribution rights and purchase option to LeMaitre Vascular, Inc. (“LeMaitre”) for $2.0 million in cash (“ProCol Sale”), all of which was received by March 31, 2016.

Disclosure of the HeRO Sale and the ProCol Sale

Financial Accounting Standards Board (“FASB”) ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, defines the criteria for reporting discontinued operations and requires additional disclosures about discontinued operations. The standard requires that an entity report as a discontinued operation only a disposal that represents a strategic shift in operations that has a major effect on the Company’s operations and financial results.

In the first quarter of 2016 the Company completed the HeRO Sale and the ProCol Sale. The Company received cash for these transactions and recorded the results of these sales in March 2016. Therefore, as of March 31, 2016 both transactions met the disposed of by sale criteria under discontinued operations.

The Company evaluated the impact of the HeRO Sale and the ProCol Sale on the Company’s business to determine whether these disposals represent a strategic shift that has, or will have, a major effect on the Company’s financial position, results of operations, or cash flows. As the HeRO Graft and ProCol product lines combined represented less than 10% of total Company revenues for the year ended December 31, 2015 and the Company’s total assets as of December 31, 2015, the Company believes that these transactions did not have a major effect on the Company’s operations and financial condition, either individually or in the aggregate, and therefore the Company did not disclose these transactions as discontinued operations. The combined net gain from the HeRO Sale and ProCol Sale was therefore reported as gain from sale of business components on the Company’s Summary Consolidated Statements of Operations and Comprehensive Income.
