Business Combinations [Abstract] |
Acquisitions | 7 Acquisitions In July 2018, the Company acquired the sole intellectual property rights to the Desorption Electrospray Ionization (“DESI”) imaging technology for $30 million in cash and a future contractual obligation to pay a minimum royalty of $3 million over the remaining life of the patent. DESI is a mass spectrometry imaging technique that is used to develop medical therapies. The Company accounted for this transaction as an asset acquisition as it did not meet the definition of a business. The Company allocated $33 million of fair value to a purchased intangible asset which will be amortized over the useful life of 12 years. In September 2016, the Company acquired all of the outstanding stock of Rubotherm GmbH (“Rubotherm”), a manufacturer of gravimetric analysis systems, for approximately $6 million in cash, $5 million of which was paid at closing and an additional $1 million paid after closing to settle certain liabilities. Rubotherm develops and manufactures analytical test instruments for thermogravimetric and sorption measurements that are used in both industrial and academic research laboratories in disciplines that include chemistry, material science and engineering. The Rubotherm acquisition will help support and further expand product offerings within TA’s thermal analysis business. In each acquisition, the sellers provided the Company with customary representations, warranties and indemnification, which would be settled in the future if and when a breach of the contractual representation or warranty condition occurs. The pro forma effect of the ongoing operations for Waters Corporation, the DESI imaging technology and Rubotherm, either individually or in the aggregate, as though these acquisitions had occurred at the beginning of the periods covered by this report was immaterial.
