2. Acquisitions and Divestitures

Acquisitions are accounted for using the acquisition method and the acquired companies’ results have been included in the accompanying consolidated financial statements from their respective dates of acquisition. In each case for the acquisitions disclosed below, pro forma information assuming the acquisition had occurred at the beginning of the earliest period presented is not included as the impact is immaterial.

Our acquisitions have historically been made at prices above the fair value of the acquired identifiable assets, resulting in goodwill, due to expectations of synergies that will be realized by combining businesses. These synergies include the use of our existing sales channel to expand sales of the acquired businesses’ products, consolidation of manufacturing facilities, and the leveraging of our existing administrative infrastructure.

The fair market valuations associated with these transactions fall within Level 3 (see Note 13) of the fair value hierarchy, due to the use of significant unobservable inputs to determine fair value. The fair value measurements were calculated using unobservable inputs, primarily using the income approach, specifically the discounted cash flow method. The amount and timing of future cash flows within our analysis was based on our due diligence models, most recent operational budgets, long range strategic plans and other estimates.

RestoreFlow Allografts

On November 10, 2016, we entered into an agreement to acquire the assets of Restore Flow Allografts, LLC, a provider of human vascular tissue processing and cryopreservation services, for an initial purchase price of $12 million, with three additional payments of up to $2 million each ($6 million in total), depending upon the satisfaction of certain contingencies. The first payment of $2 million is due not later than 15 days following the expiration of the 18 month period following the closing date, subject to reductions as specified in the agreement for each calendar month that certain retained employees are not employed by us due to resignation without good reason, or termination for cause, both as defined in the agreement. The portion of this payment that will be paid to retained employees and that is contingent on their continued employment, estimated at $0.9 million, is being accounted for as post-combination compensation expense rather than purchase consideration. The remaining $1.1 million that is payable to non-employee investors but that is also contingent on the continued employment of certain retained employees has been accounted for as contingent consideration, at an acquisition-date fair value of $0.9 million. This valuation reflects management’s assessment of the likelihood that the retained employees will remain employed by us, discounted at a rate of 6.1% to account risk inherent in the probability estimate as well as for the time value of money between acquisition date and the payment date. This valuation is being re-measured each reporting period until the payment requirement ends, with any adjustments reported in income from operations. For the year ended December 31, 2017, the amount of the adjustment was $0.1 million.

There are also two potential earn-out payments under the agreement. The first earn-out was calculated at 50% of the amount by which net revenue in the first 12 months following the closing exceeded $6 million, with such payout not to exceed $2 million. This milestone was not met and accordingly no amount was paid out. The second earn-out is calculated at 50% of the amount by which net revenue in the second 12 months following the closing exceeds $9 million, with such payout not to exceed $2 million. These earn-outs were accounted for as contingent consideration, at an acquisition-date fair value of $0.1 million for the two earn-outs combined. This valuation was derived by utilizing an option pricing model technique incorporating, among other inputs, management’s forecasts of future revenues, the expected volatility of revenues, and an estimated weighted average cost of capital 14.1% to account for the risk of achievement of the revenue forecasts as well as the time value of money between acquisition date and the payment date.

The RestoreFlow business derives revenue from human tissue preservation services, in particular the processing and cryopreservation of veins and arteries. By federal law, human tissues cannot be bought or sold. Therefore, the tissues we obtain and preserve are not held as inventory, and the costs we incur to procure and process vascular tissues are instead accumulated and deferred. Revenues are recognized for the provision of cryopreservation services rather than product sales.

The acquired assets included intellectual property, permits and approvals, data and records, equipment and furnishings, accounts receivable, inventory, literature, and customer and supplier information. We also assumed certain accounts payable. We accounted for the acquisition as a business combination.

ProCol Biologic Graft

On March 18, 2016, we acquired the ProCol biologic vascular graft (“ProCol”) business for $2.7 million from Hancock Jaffe Laboratories, Inc. (HJL) and CryoLife, Inc. (CRY). HJL was the owner and manufacturer of ProCol and CRY was the exclusive distributor of the ProCol graft. CRY also owned an option to purchase the ProCol business, which we acquired from CRY. We bought finished goods inventory and other ProCol related assets from CRY for $2.0 million, which was paid in full at closing. We bought other ProCol assets from HJL for $0.7 million, 50% of which was paid at closing, 25% of which was paid in the quarter ended September 30, 2016 and the remainder of which will be paid within one year of closing. Additional consideration is payable to HJL for a three-year period following the closing, calculated at 10% of ProCol revenues. This additional consideration was initially valued at $0.3 million and is being re-measured each reporting period until the payment requirement ends, with any adjustments reported in income from operations. For the year ended December 31, 2017, the amount of the adjustment was not material to our financial statements.

Assets acquired included inventory, intellectual property and a related license, the ProCol trade name, customer lists, non-compete agreements and certain equipment and supplies. We did not assume any liabilities. We accounted for the acquisition as a business combination.

We recorded approximately $0.2 million of intangible assets with a weighted-average amortization period of 3.0 years.

In August 2015, we entered into a definitive agreement with Grex Medical Oy (Grex), our distributor in Finland to terminate their distribution of our products, and we began selling direct to hospitals in Finland as of January 1, 2016. The agreement required us to pay approximately $0.2 million in exchange for the purchase of customer lists and a non-compete agreement.

The UnBalloon Divestiture

In July 2015, we entered into an asset sales agreement with Merit Medical Ireland Limited to sell our inventory, intellectual property, and customer lists associated with The UnBalloon non-occlusive modeling catheter product line for $0.4 million which was recognized as a gain on divestiture in the third quarter of 2015.
