Acquisitions	Acquisitions The following discussion relates to acquisitions completed during fiscal 2021, 2020, and 2019. Fiscal 2021 Acquisitions ams OSRAM's North American Digital Systems Business On July 1, 2021, using cash on hand, we acquired certain assets and liabilities of ams OSRAM’s North American Digital Systems business (“OSRAM DS”). This acquisition is intended to enhance our LED driver and controls technology portfolio and accelerate our innovation, expand our access to market through a more fulsome original equipment manufacturer (“OEM”) product offering, and give us more control over our supply chain. Rockpile Ventures On May 18, 2021, using cash on hand, we acquired all of the equity interests of Rockpile Ventures, an accelerator of edge artificial intelligence (“AI”) startups. Rockpile Ventures helps early-stage artificial intelligence companies drive co-engineering and co-selling partnerships with major cloud ecosystems, enabling faster adoption from proof-of-concept trials to market scale. Accounting for Fiscal 2021 Acquisitions We accounted for the acquisitions of Rockpile Ventures and OSRAM DS in accordance with ASC Topic 805, Business Combinations (“ASC 805”). Acquired assets and liabilities were recorded at their estimated acquisition-date fair values, and acquisition-related costs were expensed as incurred. The aggregate purchase price of these acquisitions reflects preliminary goodwill of $10.0 million and definite-lived customer-based intangible assets of $6.1 million, which have a preliminary useful life of approximately 11 years. Goodwill recognized from these acquisitions is comprised primarily of expected synergies from obtaining more control over our supply chain and technology, combining the operations of the acquired business with our operations, and acquiring the associated trained workforce. As of August 31, 2021, goodwill from these acquisitions totaling $6.9 million is expected to be tax deductible. Amounts recognized for these acquisitions are deemed to be provisional until disclosed otherwise, as we continue to gather information related to the identification and valuation of acquired assets and liabilities, including but not limited to, acquired interests in technology startups, tax-related items, final net working capital purchase adjustments, if any, and the residual impacts on the valuation of intangible assets. Fiscal 2020 and 2019 Acquisitions The Luminaires Group On September 17, 2019, using cash on hand and borrowings under available existing credit arrangements at that time, we acquired all of the equity interests of The Luminaires Group (“TLG”), a leading provider of specification-grade luminaires for commercial, institutional, hospitality, and municipal markets, all of which complement our dynamic lighting portfolio. TLG’s indoor and outdoor lighting fixtures are marketed to architects, landscape architects, interior designers, and engineers through five niche lighting brands: A-light™, Cyclone™, Eureka®, Luminaire LED™, and Luminis®. LocusLabs, Inc. On November 25, 2019, using cash on hand, we acquired all of the equity interests of LocusLabs, Inc (“LocusLabs”).
