Business Combinations Acquisition of American Development Corporation of Tennessee, Inc. : On July 28, 2020, we acquired substantially all the assets of American Development Corporation of Tennessee, Inc. (ADC) under the terms of an asset purchase agreement with ADC and its shareholders. We paid $25 million for the acquisition, using funds available on our revolver to fund the acquisition. ADC is a water treatment chemical distribution company operating primarily in Tennessee, Georgia and Kentucky. The results of operations since the acquisition date, and the assets, including the goodwill associated with this acquisition, are included in our Water Treatment segment. Costs associated with this transaction were not material and were expensed as incurred. The acquisition has been accounted for under the acquisition method of accounting, under which the total purchase price is allocated to the net tangible and intangible assets and liabilities of ADC acquired in connection with the acquisition based on their estimated fair values. We estimated the fair values of the assets acquired and liabilities assumed using a discounted cash flow analysis (income approach). Of the $25 million purchase price, we allocated $13.3 million to finite-lived intangible assets, primarily customer relationships to be amortized over 17 years, $1.6 million to property, plant and equipment, and $0.9 million to net working capital. The residual amount of $9.2 million was allocated to goodwill. The goodwill recognized as a result of this acquisition is primarily attributable to strategic and synergistic benefits, as well as the assembled workforce. Such goodwill is expected to be deductible for tax purposes. The purchase price allocation is preliminary and subject to adjustment within the first 12 months following the acquisition.
