Business Acquisitions Acquisition of Microsemi On May 29, 2018 , the Company completed its acquisition of Microsemi Corporation, a publicly traded company headquartered in Aliso Viejo, California. The Company paid an aggregate of approximately $8.19 billion in cash to the stockholders of Microsemi. The total consideration transferred in the acquisition, including approximately $53.9 million of non-cash consideration for the exchange of certain share-based payment awards of Microsemi for stock awards of the Company, was approximately $8.24 billion . In addition to the consideration transferred, the Company recognized in its consolidated financial statements $3.15 billion in liabilities of Microsemi consisting of debt, taxes payable and deferred, restructuring, and contingent and other liabilities of which $2.06 billion of existing debt was paid off. The Company financed the purchase price using approximately $8.10 billion of borrowings consisting of $3.10 billion under its amended and restated revolving line of credit (the "Credit Facility"), $3.0 billion under the term loan feature of the Credit Facility ("Term Loan Facility"), and $2.0 billion in newly issued senior secured notes. The Company incurred $22.0 million in acquisition costs related to the acquisition. As a result of the acquisition, Microsemi became a wholly owned subsidiary of the Company. Microsemi offers a comprehensive portfolio of semiconductor and system solutions for aerospace and defense, communications, data center and industrial markets. The Company's primary reason for this acquisition was to expand the Company's range of solutions, products and capabilities by extending its served available market. The acquisition was accounted for under the acquisition method of accounting, with the Company identified as the acquirer, and the operating results of Microsemi have been included in the Company's consolidated financial statements as of the closing date of the acquisition. Under the acquisition method of accounting, the aggregate amount of consideration paid by the Company was allocated to Microsemi's net tangible assets and intangible assets based on their estimated fair values as of May 29, 2018 . The excess of the purchase price over the value of the net tangible assets and intangible assets was recorded to goodwill. The factors contributing to the recognition of goodwill were based upon the Company's conclusion that there are strategic and synergistic benefits that are expected to be realized from the acquisition. The goodwill has been allocated to the Company's semiconductor products reporting segment. None of the goodwill related to the Microsemi acquisition is deductible for tax purposes. The Company has retained independent third-party appraisers to assist management in its ongoing valuation of the acquired assets and liabilities. The purchase price allocation has not been finalized and is based on estimates and assumptions that are subject to change related to the valuation of inventory, intangible assets, taxes and other assets and liabilities. This could result in adjustments to the fair values of the assets acquired and liabilities assumed, the useful lives of intangible assets, the residual amount allocated to goodwill and deferred income taxes recognized. The preliminary allocation of the purchase price is based on the best estimates of management and is subject to revision based on the final valuation and estimates of useful lives. The purchase price allocation is preliminary and could change materially during the measurement period. The table below represents the preliminary allocation of the purchase price to the net assets acquired based on their estimated fair values, as well as the associated estimated useful lives of the acquired intangible assets (in millions).

The estimated fair values of the core and developed technology and in-process research and development are being determined based on the present value of the expected cash flows to be generated by the respective existing technology or future technology. The core and developed technology intangible assets are being amortized in a manner based on the expected cash flows used in the initial determination of fair value. In-process research and development is capitalized until such time as the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off. Customer-related intangible assets consist of Microsemi's contractual relationships and customer loyalty related to its distributor and end-customer relationships. The fair values of the customer-related intangibles are being determined based on expected attrition and revenue growth for Microsemi's existing customers as of the acquisition date. Customer relationships are being amortized in a manner based on the estimated cash flows associated with the existing customers and anticipated retention rates. Backlog relates to the value of orders not yet shipped by Microsemi at the acquisition date, and the fair values are being determined based on the estimated profit associated with those orders. Backlog related assets had a one year useful life and are being amortized on a straight-line basis over that period. The total weighted average amortization period of intangible assets acquired as a result of the Microsemi transaction is 9 years . Amortization expense associated with acquired intangible assets is not deductible for tax purposes. Thus, approximately $851.4 million was established as a net deferred tax liability for the future amortization of the intangible assets. The amount of Microsemi net sales included in the Company's condensed consolidated statements of income for the three and six months ended September 30, 2018 was approximately $431.7 million and $620.2 million , respectively. The amount of Microsemi net loss included in the Company's condensed consolidated statements of income for the three and six months ended September 30, 2018, was approximately $216.4 million and $250.4 million , respectively. The following unaudited pro-forma consolidated results of operations for the three and six months ended September 30, 2018 and 2017 assume the closing of the Microsemi acquisition occurred as of April 1, 2017. The pro-forma adjustments are mainly comprised of acquired inventory fair value costs and amortization of purchased intangible assets.
