In May 2017, we purchased the remaining minority interest position in US Imaging. In May 2016, the Company closed a transaction to acquire Cuattro Veterinary, LLC ("International Imaging"), which was owned by Kevin S. Wilson, among other members. International Imaging is a provider to international markets of digital radiography technologies for veterinarians. As a leading provider of advanced veterinary diagnostic and specialty products, we made the acquisition in an effort to combine International Imaging's global reach with our domestic success in the imaging and laboratory markets in the United States. In June 2017, the Company consolidated its assets and liabilities in the US Imaging and International Imaging companies into Heska Imaging, LLC ("Heska Imaging"). Cuattro, LLC ("Cuattro") is owned by Kevin S. Wilson, the CEO and President of the Company in addition to Mrs. Wilson and trusts for the benefit of Mr. and Mrs. Wilson's children and family.

Purchase Agreement for Certain Assets On December 21, 2018, the Company closed a transaction (the "Asset Acquisition") to acquire certain assets from Cuattro, all related to the CCA segment. Pursuant to the Asset Acquisition, dated November 26, 2018, the Company issued 54,763 shares of the Company's common stock, $0.01 par value per share (the "Common Stock"), to Cuattro on the closing date, at an aggregate value equal to approximately $5.4 million based on the adjusted closing price per share of the Common Stock as reported on the Nasdaq Stock Market on the Asset Acquisition agreement date. These shares were issued to Cuattro in a private placement in reliance upon an exemption from the registration requirements of the Securities Act pursuant to Section 4(a)(2) thereof and the safe harbor provided by Rule 506 of Regulation D promulgated thereunder. In addition to the Common Stock, the Company paid cash in the amount of $2.8 million to Cuattro as part of the transaction. The total purchase price was determined based on a valuation report from an independent third party. Part of the Asset Acquisition was an agreement to terminate the supply and license agreement that Heska had been operating under since the acquisition of Cuattro Veterinary USA, LLC. The Company evaluated the acquisition of the purchased assets under ASC 805, Business Combinations and ASU 2017-01, Business Combinations (Topic 805) and concluded that as substantially all of the fair value of the gross assets acquired is concentrated in an identifiable group of similar assets, the transaction did not meet the requirements to be accounted for as a business combination and therefore was accounted for as an asset acquisition. Accordingly, the purchase price of the purchased assets was allocated entirely to an identifiable intangible asset. In addition to the software assets acquired, Cuattro is obligated, without further compensation, to assist the Company with the implementation of a third-party image hosting platform and necessary data migration. Other Related Party Activities Cuattro charged Heska Imaging $6.0 thousand and $2.3 million during the six months ended June 30, 2019 and 2018, respectively. The charge in 2019 relates to minor inventory purchases as the Company transitions the digital imaging software assets away from Cuattro. The charge in 2018 was primarily for digital imaging products, pursuant to an underlying supply contract which was terminated in December 2018. The Company had no receivables from or payables to Cuattro as of June 30, 2019. Heska Imaging owed Cuattro $0.2 million as of December 31, 2018, which is reported in "Due to – related parties" on the Company's Condensed Consolidated Balance Sheets.
