On August 31, 2018, we acquired 100% of the outstanding stock of Flight Systems Automotive Group LLC (“Flight Systems” or “Flight”), a privately-held manufacturer and remanufacturer of complex automotive electronics and diesel fuel system components, based in Lewisberry, Pennsylvania. The purchase price was $27.5 million. We believe complex electronics and diesel fuel system components represent important growth opportunities for us and Flight’s product portfolio delivers valuable alternatives to aftermarket professionals.

The transaction was accounted for as a business combination under the acquisition method of accounting. Accordingly, the assets acquired and liabilities assumed were recorded at fair value, with the remaining purchase price recorded as goodwill.

In connection with this acquisition, we preliminary recorded $5.5 million in goodwill, $5.3 million of identified intangibles, and $16.7 million of other net assets, primarily $2.0 million of accounts receivable, $9.1 million of inventory, $4.4 million of fixed assets, and $1.2 million of net other assets and liabilities. The estimated fair value of the Flight assets acquired and liabilities assumed are provisional as of March 30, 2019 and are based on information that is currently available to the Company. Additional information about conditions that existed as of the date of acquisition are being gathered to finalize these provisional measurements, particularly with respect to net working capital, intangible assets, deferred income taxes and tax liabilities. Accordingly, the measurement of Flight’s assets acquired and liabilities assumed may change significantly upon finalization of the Company’s valuations and completion of the purchase price allocation, both of which are expected to occur no later than one year from the acquisition date.

The valuation of the intangible assets acquired and related amortization periods are as follows:

(in thousands)	Valuation		Amortization Period (in years)
Customer relationships	$	3,080		8
Tradenames		1,990	15
Other		240		5
Total	$	5,310

The preliminary fair values of the Customer relationships and Tradenames were estimated using a discounted present value income approach.

The goodwill recognized is attributable primarily to strategic and synergistic opportunities related to existing automotive aftermarket businesses, the assembled workforce of Flight and other factors. The goodwill is expected to be deductible for tax purposes.

The financial results of the acquisition have been included in the Consolidated Financial Statements since the date of acquisition.

On October 26, 2017, we acquired 100% of the outstanding stock of MAS Automotive Distribution Inc. (“MAS”), a privately-held manufacturer of premium chassis and control arms based in Montreal, Canada. The purchase price was $67.2 million net of $3.3 million of cash acquired and including contingent consideration and other purchase price adjustment. The fair value of the contingent cash consideration was estimated by using an option pricing model framework, which represents our own assumptions and data, and is based on our best available information. As of March 30, 2019, we had $8.1 million recorded which represent the fair value of the estimated payment which will become due if certain sales thresholds are achieved through December 2020. Accretion expense was $0.1 million in each of the thirteen weeks ended March 30, 2019 and March 31, 2018, which was included in selling, general and administrative expenses in the Consolidated Statements of Income.
