Payable to acquire productive assets

  
NOTE 4. ACQUISITIONS, ASSET PURCHASES AND INVESTMENTS  
We believe that our acquisitions of businesses and other assets enhance our existing businesses by either expanding our geographic range and customer base, or expanding our existing product lines. From time to time we may acquire small reference laboratory or radiology practices that we account for as either asset purchases or business combinations.   
Asset Purchases and Investments  
During 2022, we entered into two discrete arrangements to license intellectual property for which we paid $55.0 million and accrued $25.0 million in subsequent payments, all of which was charged to research and development expense. These two arrangements were treated as asset acquisitions under U.S. GAAP and resulted in the full amount being expensed to research and development expense as in-process research and development costs with no alternative future use. The acquisition of these licensing arrangements supports new instrument platform advancements. We also made a $10.0 million payment for a perpetual intellectual property license, which will be amortized over 10 years. The research and development expense and amortization expense were recorded in our CAG segment.   
During 2022 we also purchased $25.0 million of preferred shares for a noncontrolling minority interest in one of the entities with which we have a license agreement. We have elected to measure the investment as an equity security investment, under ASC 321, “Investment - Equity Securities,” and recorded the investment at cost. The investment is included in other long-term assets.  
Business Combinations  
During the third quarter of 2022, we acquired the assets of an international water testing company located in Canada for approximately $12.8 million in cash, including a holdback of approximately $1.3 million. This acquisition expands our product offering in the Water segment. The preliminary fair value of the assets and liabilities acquired consists of technology intangibles of approximately $3.4 million, with a life of 10 years; customer relationship intangibles of approximately $1.2 million, with a life of 10 years; approximately $6.7 million of goodwill, representing synergies with our Water testing portfolio; and approximately $1.5 million of new tangible assets, including inventory and accounts receivable. Goodwill related to this acquisition is expected to be deductible for tax purposes. The purchase price allocation is subject to revision as additional information becomes available from third-parties regarding valuation of intangibles, tax matters, and certain assets and liabilities.

The fair values of the assets acquired consist of customer relationship intangibles of approximately $7.4 million, with a life of 10 years; a non-compete agreement of approximately $0.8 million, with a life of 3 years; approximately $6.9 million of goodwill, representing synergies within our broader CAG portfolio; and approximately $1.7 million in net tangible liabilities, including deferred taxes associated with the acquired intangible assets.
