Business Combinations [Abstract] |
Schedule of Business Combinations | As part of our ongoing strategy to expand geographically and increase market share in certain markets, we completed ten, ten and nine business combinations during the years ended December 31, 2018, 2017 and 2016, respectively, as well as several insignificant tuck-in acquisitions merged into existing operations in 2018 and 2017, in which we acquired 100% of the voting equity interests in each acquired entity. Acquisition-related costs amounted to $2.7 million, $3.9 million and $2.3 million for the years ended December 31, 2018, 2017 and 2016, respectively, and are included in Administrative expenses on the Consolidated Statements of Operations and Comprehensive Income. The goodwill to be recognized in conjunction with these business combinations represents the excess cost of the acquired entity over the net amount assigned to assets acquired and liabilities assumed. We expect to deduct $17.3 million of goodwill for tax purposes as a result of 2018 acquisitions. The largest of our 2018 acquisitions was Custom Overhead Door, LLC dba Custom Door & Gate (collectively, “CDG”) and Advanced Fiber Technology, Inc. (collectively, “AFT”). The remaining acquisitions were individually insignificant but material in the aggregate, as follows. Net income (loss), as noted below, includes amortization, taxes and interest allocations when appropriate. Below is a summary of each significant acquisition by year, including revenue and net income (loss) since date of acquisition, shown for the year of acquisition. For the year ended December 31, 2018 (in thousands):

(1) | The cash paid included $21.7 million in contingent consideration to satisfy purchase price adjustments related to cash and net working capital requirements, earnout consideration based on Alpha’s change in EBITDA from 2015 and a customary holdback. These payments were based on fair value of each contingent payment at the time of acquisition and subsequently adjusted during the measurement period. We issued 282,577 shares of our common stock with a fair value of $10.9 million.
