BUSINESS ACQUISITIONS Acquisition of R&amp;D Entities Effective December 31, 2019, we completed the acquisition of R&amp;D Test Systems, R&amp;D Engineering, R&amp;D Steel, R&amp;D Prague, RGDK Engineering Private Limited and R&amp;D Tools and Structures (collectively, R&amp;D) for an upfront cash purchase price of $58,280 . The acquisition was primarily funded through our existing Revolving Credit Facility. The remaining purchase price is based on earn-out payments of up to an additional $26,000 contingent on financial performance through June 2021. As of the acquisition date, we estimated the fair value of the earn-out liability (contingent consideration) to be $17,447 . Based out of Denmark, R&amp;D is a leader in high-quality, durable, rotating test systems, serving primarily the wind energy markets. During the three and six months ended March 28, 2020 , we included $14,708 of revenue from R&amp;D in our Consolidated Statements of Income. Costs of $1,340 associated with the acquisition of R&amp;D were expensed as incurred. Pro forma information related to the acquisition of R&amp;D has not been included as the impact on our consolidated results of operations was not considered material. The following table summarizes the preliminary fair value measurement of the assets acquired as of the date of acquisition: Fair Value Finite-Lived Intangible Asset Lives (Years) Asset (Liability) Accounts receivable $ 13,557 Unbilled accounts receivable 6,325 Inventories 41 Prepaid expenses and other current assets 533 Property and equipment 1,185 Intangible assets Customer lists 24,282 15 Trademarks and trade names 8,539 15 Technology 5,075 10 Other intangible assets 4,198 1 Other long-term assets 3,121 Purchased goodwill 36,461 Accounts payable (12,592 ) Accrued payroll and related costs (2,193 ) Advanced payments from customers (3,203 ) Accrued income taxes (1,113 ) Other accrued liabilities (5,074 ) Deferred income taxes (10,103 ) Other long-term liabilities (2,230 ) Net assets acquired $ 66,809 Supplemental information Consideration paid at closing $ 58,280 Estimated contingent consideration 17,447 Less: Cash acquired (8,918 ) Purchase price, net of cash acquired $ 66,809 The allocation of purchase price consideration is considered preliminary as of March 28, 2020 with provisional amounts related to accounts receivable, unbilled accounts receivable, property and equipment, intangible assets, accounts payable, advanced payments from customers, accrued income taxes, other accrued liabilities, deferred income taxes and purchase price adjustments included, which includes the contingent consideration, as our allocation process has not been finalized. We expect to finalize the allocation of purchase price as soon as possible, but no later than one year from the acquisition date. Goodwill was calculated as the difference between the acquisition date fair value of the total purchase price consideration and the fair value of the net assets acquired and represents the future economic benefits that we expect to achieve as a result of the acquisition. This resulted in a purchase price in excess of the fair value of identifiable assets acquired. The purchase price also included the fair value of other assets that were not identifiable, not separately recognizable under accounting rules (e.g., assembled workforce) or of immaterial value. All of the goodwill was assigned to Test &amp; Simulation. No ne of the goodwill is deductible for income tax purposes. The fair value of the acquired intangible assets was $42,094 .
