Business Combinations [Abstract]
Acquisitions and disposition	Acquisitions and Disposition For all acquisitions, the Company allocates the purchase price to assets acquired and liabilities assumed as of the date of acquisition based on the estimated fair values at the date of acquisition. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Management makes significant estimates and assumptions when determining the fair value of assets acquired and liabilities assumed. These estimates include, but are not limited to, discount rates, projected future net sales, projected future expected cash flows and useful lives. The Company accounts for all acquisitions using the acquisition method of accounting under ASC 805, Business Combinations (“ASC 805”), whereby the results of operations of the acquired company are included in the Company’s consolidated financial statements beginning on the acquisition date. 2018 Disposition On November 1, 2018, the Company completed the sale of substantially all of the assets and certain liabilities of its Coleman Floor business (“Coleman Floor”) for a preliminary sale price of $7.8 million, subject to certain customary post-closing adjustments. For the year ended December 31, 2018, the net sales of Coleman Floor represented approximately 1% of the Company’s net sales. The sale does not represent a strategic shift under ASC 205, Presentation of Financial Statements, and as such, is not reported as a discontinued operation in the Company’s consolidated financial statements. The Company recognized a loss on the sale of $0.3 million, which is included in other income, net in the consolidated statements of operations. 2018 Acquisition On March 1, 2018, the Company acquired substantially all of the assets and assumed certain liabilities of W.E. Shone Co. (“Shone Lumber”), a supplier of building materials in the state of Delaware, for a preliminary purchase price of $22.4 million. This acquisition enhances the Company’s value-added offerings and footprint in the Mid-Atlantic region. The preliminary purchase price includes a holdback which, after certain post-closing adjustments, requires the Company to pay $1.4 million to the sellers one year from the closing date. The holdback amount may be further reduced under certain circumstances. The Company funded the transaction through available cash and borrowings on the Company’s revolving line of credit. The purchase price allocation resulted in the recognition of goodwill of $2.5 million, a customer relationship intangible asset of $7.0 million, accounts receivable of $6.4 million, inventory of $8.8 million, property and equipment of $2.9 million and total current liabilities of $5.3 million, as well as other operating assets. The customer relationship intangible asset has a useful life of 9 years. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes. For the year ended December 31, 2017, Shone Lumber generated net sales of approximately $70.7 million. The Company incurred transaction costs of $0.2 million for the year ended December 31, 2018, which are included in selling, general and administrative expenses in the consolidated statements of operations. Net sales and estimated pre-tax earnings for Shone Lumber included in the consolidated statements of operations from the March 1, 2018 acquisition date to December 31, 2018 were $60.9 million and $3.2 million, respectively. The impact of the acquisition was not considered significant for the reporting of pro forma financial information. 2017 Acquisitions On April 3, 2017, the Company acquired substantially all of the assets and assumed certain liabilities of Texas Plywood & Lumber Company, Inc. (“TexPly”), a supplier of production millwork and doors in the Dallas-Fort Worth area, for a purchase price of $31.7 million. This acquisition enhances the Company’s value-added offerings and footprint in the Dallas-Fort Worth market. The Company funded the transaction through borrowings on the Company’s revolving line of credit. The purchase price allocation resulted in the recognition of goodwill of $3.6 million, a customer relationship intangible asset of $13.6 million, accounts receivable of $5.2 million, inventory of $3.9 million and real property of $5.4 million, as well as other operating assets and liabilities. The customer relationship intangible asset has a useful life of 13 years. Goodwill represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including assembled workforce and non-contractual relationships, as well as expected future synergies. All of the goodwill recognized is expected to be deductible for tax purposes. On March 27, 2017, the Company acquired substantially all of the assets and assumed certain liabilities of Code Plus Components, LLC (“Code Plus”), a manufacturer of structural components located in Martinsburg, West Virginia, for a purchase price of $7.1 million. This acquisition allowed the Company to add truss manufacturing capability to its value-added offerings in the Washington, DC metro area. The acquisition includes an earnout provision that requires the Company to pay the sellers an additional $0.8 million during the year ended December 31, 2019, due to the acquired operations achieving certain performance targets from the acquisition date through December 31, 2018. The Company funded the transaction through borrowings on the Company’s revolving line of credit. The purchase price allocation resulted in the recognition of goodwill of $3.4 million, a customer relationship intangible asset of $2.3 million and a non-compete agreement intangible asset of $0.5 million, as well as other operating assets and liabilities. The customer relationship intangible asset and non-compete agreement intangible asset have useful lives of 12 years and 5 years, respectively.
