On November 6, 2020, we entered into a unit purchase agreement to acquire KA Medical, LLC (“KA Medical”). Subject to the terms and conditions of the unit purchase agreement, we paid $10.4 million in cash at closing, net of cash acquired, subject to adjustments for working capital and other matters, with an additional $4 million payable no later than 12 months following the agreement. KA Medical developed the Micro Plug Set, a self-expanding nitinol vascular occlusion device, which is FDA-cleared and CE marked. We accounted for this acquisition as a business combination. The sales and results of operations related to the acquisition have been included in our cardiovascular segment since the acquisition date and were not material. Acquisition-related costs associated with the KA Medical acquisition, which were included in selling,

general and administrative expenses, were not material. The purchase price was preliminarily allocated as follows (in thousands):

We are amortizing the developed technology intangible asset acquired from KA Medical over 17 years. The goodwill consists largely of the synergies expected from combining operations and is expected to be deductible for income tax purposes.

On October 11, 2019, we entered into a subscription and shareholders’ agreement to acquire 3,900 ordinary shares and 1,365 C ordinary shares of Selio Medical Limited ("Selio"), an option to purchase all ordinary shares in Selio throughout a 45 day period commencing from the date Selio receives FDA Section 510(k) approval of a medical device it is currently developing, and an option to purchase all remaining shares on the third anniversary date of the agreement if we elect to purchase all ordinary shares. The shares of stock we acquired, which represent an ownership interest of approximately 19.5%, have been recorded as an equity investment accounted for at cost because we are not able to exercise significant influence over the operations of Selio. The investment and purchase option of approximately $2.6 million are reflected within other assets in the accompanying consolidated balance sheets. In addition, we have a loan to Selio of $250,000, reflected within other assets, and have committed to provide a loan up to an additional €2 million at the discretion of the borrower. Amounts outstanding under the loan accrue interest at a rate of 5% per annum. All amounts outstanding under the loan agreement become due and payable at the first anniversary of the expiration of our option to purchase all ordinary shares.

On August 1, 2019, we entered into a share purchase agreement to acquire Fibrovein Holdings Limited, which is the owner of 100% of the capital stock of STD Pharmaceutical Products Limited, a UK private company engaged in the manufacture, distribution and sale of pharmaceutical sclerotherapy products (“STD Pharmaceutical”). The purchase consideration consisted of an upfront payment of approximately $13.7 million, net of cash acquired. We also recorded a contingent consideration liability of $934,000 related to royalties potentially payable pursuant to the terms of the share purchase agreement. We accounted for this acquisition as a business combination.

On June 14, 2019, we consummated an acquisition transaction contemplated by a merger agreement to acquire Brightwater Medical, Inc. ("Brightwater"). The purchase consideration consisted of an upfront payment of $35 million plus an immaterial working capital adjustment, net of cash acquired, with potential earn-out payments of up to an additional $5 million for achievement of CE certification with respect to the ConvertX®, a single-use device used to replace a series of devices and procedures used to treat severe obstructions of the ureter, and up to an additional $10 million for the achievement of sales milestones specified in the merger agreement. The ConvertX device is designed to be implanted once and converted from a nephroureteral catheter to a nephroureteral stent without requiring sedation or local anesthesia.

Brightwater recently received FDA clearance for the ConvertX biliary stent device. We accounted for this acquisition as a business combination.

On March 28, 2019, we paid $2 million to acquire convertible participating preferred shares of Fluidx Medical Technology, LLC ("Fluidx"), owner of certain technology proposed to be used in the development of embolic and adhesive agents for use in arterial, venous, vascular graft and cardiovascular applications inside and outside the heart and related appendages. Our investment in Fluidx has been recorded as an equity investment accounted for at cost and reflected within other assets in our accompanying consolidated balance sheet because we are not able to exercise significant influence over the operations of Fluidx. Our total current investment in Fluidx represents an ownership of approximately 11.6% of the outstanding equity interests of Fluidx.

The following table summarizes the purchase price allocation and other disclosures for acquisitions accounted for as business combinations during the year ended December 31, 2019 (in thousands). During the year ended December 31, 2020, certain non-significant measurement period adjustments were recorded to our purchase price allocation for the assets acquired from Brightwater, including reassessment of tax assets and liabilities.

The sales and results of operations related to the STD Pharmaceutical and Brightwater acquisitions have been included in our cardiovascular segment and were not material. It is not practical to separately report earnings related to these acquisitions, as we cannot split out sales costs related solely to the products acquired, principally because our sales representatives sell multiple products within our cardiovascular business segment. Acquisition costs related to the STD Pharmaceutical and Brightwater acquisitions, which were included in selling, general and administrative expenses, were not material. Goodwill related to these acquisitions arises principally from synergies and economies of scale anticipated upon consolidation of operations and is not expected to be deductible for income tax purposes.

On December 14, 2018, we consummated an acquisition transaction contemplated by an asset purchase agreement with Vascular Insights, LLC and VI Management, Inc. (combined "Vascular Insights") and acquired Vascular Insights’ intellectual property rights, inventory and certain other assets, including, the ClariVein® IC system and the ClariVein OC system. The ClariVein systems are specialty infusion and occlusion catheter systems with rotating wire tips designed for the controlled 360-degree dispersion of physician-specified agents to a targeted treatment area. We accounted for this acquisition as a business combination. The purchase consideration included an upfront payment of $40 million and an immaterial working capital adjustment. We are also obligated to pay up to an additional $20 million based on achieving certain revenue milestones specified in the asset purchase agreement.

On November 13, 2018, we consummated an acquisition transaction contemplated by a merger agreement to acquire Cianna Medical, Inc. ("Cianna Medical").

Cianna Medical developed the first non-radioactive, wire-free breast cancer localization system. Its SCOUT® and SAVI® Brachy technologies are FDA-cleared and address unmet needs in the delivery of radiation therapy, tumor localization and surgical guidance. We accounted for this acquisition as a business combination.

During July 2018, we purchased 1,786,000 preferred limited liability company units of Cagent Vascular, LLC, a medical device company ("Cagent"), for approximately $2.2 million. We had previously purchased 3,000,000 preferred limited liability company units of Cagent for approximately $3.0 million during 2016 and 2017. Our investment has been recorded as an equity investment accounted for at cost and reflected within other assets in the accompanying consolidated balance sheets because we are not able to exercise significant influence over the operations of Cagent. Our total current investment in Cagent represents an ownership of approximately 19.5% of the outstanding stock.

On May 23, 2018, we entered into an asset purchase agreement with DirectACCESS Medical, LLC (“DirectACCESS”) to acquire its assets, including, certain product distribution agreements for the FirstChoice™ Ultra High-Pressure PTA Balloon Catheter. We accounted for this acquisition as a business combination. The purchase price for the assets was approximately $7.3 million.

On May 18, 2018, we paid $750,000 for a distribution agreement with QXMédical, LLC ("QXMédical") for the Q50® PLUS Stent Graft Balloon Catheter. We accounted for this acquisition as an asset purchase. We are amortizing the distribution agreement intangible asset over a period of ten years.

On April 6, 2018, we entered into long-term agreements with NinePoint, pursuant to which we (a) became the exclusive worldwide distributor for the NvisionVLE® Imaging System with Real-time Targeting™ using Optical Coherence Tomography (OCT) and (b) acquired an option to purchase up to 100% of the outstanding equity in NinePoint throughout a three-month period commencing 18 months subsequent to the agreement date, both in exchange for total consideration of $10 million. In addition, we made a loan to NinePoint for $10.5 million with a maturity date of April 6, 2023, at which time the loan, together with accrued interest thereon, will be due and payable. The loan bears interest at a rate of 9.0% and is collateralized by NinePoint’s rights, interest and title to the NvisionVLE® Imaging System and any other product owned or licensed by NinePoint utilizing OCT. This loan has been recorded as a note receivable within other long-term assets in our consolidated balance sheets. We utilized the consolidation of variable interest entities guidance to determine whether or not NinePoint was a variable interest entity ("VIE"), and if so, whether we are the primary beneficiary of NinePoint. As of December 31, 2018, we concluded that NinePoint is a VIE based on the fact that the equity investment at risk in NinePoint is not sufficient to finance its activities. We have also determined that Merit is not the primary beneficiary of NinePoint as we do not have the power to direct NinePoint’s most significant activities. The results of operations related to NinePoint have been included in our endoscopy segment since the acquisition date. During the years ended December 31, 2019 and 2018 our net sales of NinePoint products were approximately $2.9 million and $3.0 million, respectively. Our exposure to loss related to our transaction with NinePoint was the carrying value of the amounts paid to and due from NinePoint. In 2019, we determined our investments in NinePoint were impaired, and we recorded impairment charges of $20.5 million for the NinePoint note receivable and purchase option and $1.6 million related to interest accrued on the note receivable. In January 2020, our option to purchase the outstanding equity of NinePoint expired.

On February 14, 2018, we acquired certain divested assets from Becton, Dickinson and Company ("BD"), for an aggregate purchase price of $100.3 million. We also recorded a contingent consideration liability of $1.6 million related to milestone payments payable pursuant to the terms of the acquired contract with Sontina Medical LLC. The assets acquired include the soft tissue core needle biopsy products sold under the tradenames of Achieve® Programmable Automatic Biopsy System, Temno® Biopsy System and TruCut® Biopsy Needles as well as the Aspira® Pleural Effusion Drainage Kits, and the Aspira® Peritoneal Drainage System. We accounted for this acquisition as a business combination.

The following table summarizes the purchase price allocation and other required disclosures for acquisitions accounted for as business combinations during the year ended December 31, 2018 (in thousands).

The sales and results of operations related to these acquisitions have been included in our cardiovascular segment. It is not practical to separately report earnings related to these acquisitions, as we cannot split out sales costs related solely to the products acquired, principally because our sales representatives sell multiple products within our cardiovascular business segment. Acquisition costs related to these acquisitions were included in selling, general and administrative expenses. Acquisition costs related to the Vascular Insights and DirectAccess acquisitions were not material, and acquisition costs related to the Cianna Medical and BD acquisitions were $3.5 million and $1.8 million, respectively. Goodwill related to these acquisitions arises principally from synergies and economies of scale anticipated upon consolidation of operations. Goodwill related to the Cianna Medical acquisition is not expected to be deductible for income tax purposes, while

goodwill related to the Vascular Insights, DirectAccess, and BD acquisitions is expected to be deductible for income tax purposes.

The following table summarizes our consolidated results of operations for the year ended December 31, 2018, as well as unaudited pro forma consolidated results of operations as though the 2018 acquisitions of Cianna Medical and Vascular Insights had occurred on January 1, 2017 (in thousands, except per common share amounts):

Note: The pro forma results for the years ended December 31, 2020 and 2019 are not included in the table above because the operating results of the Cianna Medical, and Vascular Insights acquisitions were included in our consolidated statements of income (loss) for these periods.

The unaudited pro forma information set forth above is for informational purposes only and includes adjustments related to the step-up of acquired inventories, amortization expense of acquired intangible assets, stock-based compensation for cancelled or forfeited options, and interest expense on long-term debt. The pro forma information should not be considered indicative of actual results that would have been achieved if the acquisition of Cianna Medical and Vascular Insights had occurred on January 1, 2017, or results that may be obtained in any future period. The pro forma consolidated results of operations do not include the 2018 acquisition of assets from BD because it was deemed impracticable to obtain information to determine net income associated with the acquired product lines which represent a small product line of a large, consolidated company without standalone financial information. We do not deem the pro forma effects to our consolidated results of operations of the KA Medical, STD Pharmaceutical, Brightwater and DirectACCESS acquisitions to be material.
