Sale of Business Components Divestiture of the HeRO Graft Product Line On February 3, 2016 we sold our Hemodialysis Reliable Outflow Graft (“HeRO® Graft”) product line to Merit Medical Systems, Inc. (“Merit”) for $18.5 million in cash (“HeRO Sale”), of which $17.8 million was received on the transaction date and 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. We continued to manufacture the HeRO Graft under a transition supply agreement until the manufacturing transfer to Merit was completed in the second quarter of 2016. Sales prices under the transition supply agreement were at lower average prices than our previous sales to hospitals at end-user prices. The HeRO Graft product line was included as part of our Medical Devices segment. We recorded a pre-tax gain of approximately $8.8 million on the HeRO Sale. ProCol Distribution Agreement and Divestiture of the ProCol Product Line On March 18, 2016 we sold our 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 the terms of the agreement, LeMaitre acquired the ProCol related assets, including inventory, customer lists, related marketing assets, and our purchase option to acquire ProCol. LeMaitre exercised the option to acquire ProCol from Hancock Jaffe Laboratories, Inc. The ProCol product was included as part of our Medical Devices segment. We 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 ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, (“ASU 2014-08”) defines the criteria for reporting discontinued operations and requires additional disclosures about discontinued operations. The standard requires that an entity report a disposal as a discontinued operation only if the disposal represents a strategic shift in operations that has a major effect on our operations and financial results. In the first quarter of 2016 we completed and recorded the HeRO Sale and the ProCol Sale and received cash for these transactions. Therefore, as of March 31, 2016 both transactions met the disposed of by sale criteria under ASU 2014-08. We evaluated the impact of the HeRO Sale and the ProCol Sale on our business to determine whether these disposals represent a strategic shift that has, or will have, a major effect on our financial position, results of operations, or cash flows. As the HeRO Graft and ProCol product lines combined accounted for less than 10% of both our total revenues for the year ended December 31, 2015 and our total assets as of December 31, 2015, we believe that these transactions did not have a major effect on our operations and financial condition, either individually or in the aggregate, and therefore, we 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 our Consolidated Statements of Operations and Comprehensive (Loss) Income.
