As a result of the July 1, 2018 segment realignment, the Company reviewed the recoverability of the carrying value of goodwill at its reporting units. The Company performed a quantitative test to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill and other intangible assets. The Company did not record any impairment of goodwill or long-lived assets, as the quantitative assessment did not indicate deterioration in the fair value of its reporting units.

In conjunction with the acquisition of CoAdna, the Company recorded $9.8 million attributed to the value of technology and patents and $6.3 million of customer lists. The intangibles were recorded based on the Company’s preliminary purchase price allocation utilizing either a discounted cash flow or relief from royalty method to derive the fair value. The valuation is expected to be finalized within one year from the date of acquisition.

In conjunction with the acquisition of the product line, the Company recorded $6.3 million of acquired technology.
