NOTE 15  BUSINESS COMBINATIONS As part of our ongoing strategy to expand geographically and increase market share in certain markets, we completed one business combination and one insignificant tuck-in acquisition merged into existing operations during the three months ended March 31, 2019 and two business combinations and one insignificant tuck-in acquisition merged into existing operations during the three months ended March 31, 2018, respectively, in which we acquired 100 % of the ownership interests in each. The largest of these acquisitions were 1st State Insulation, LLC (1st State Insulation) in March 2019 and Custom Overhead Door, LLC dba Custom Door &amp; Gate (collectively, CDG) in March 2018. Net Income, 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 (in thousands): Total Three months ended Acquisition Cash Seller Purchase March 31, 2019 2019 Acquisitions Date Type Paid Obligations Price Revenue Net Income 1st State Insulation 3/18/2019 Asset $ 5,125 $ 1,380 $ 6,505 $ 488 $ 23 Three months ended Acquisition Seller Total Purchase March 31, 2018 2018 Acquisitions Date Type Cash Paid Obligations Price Revenue Net (Loss) Income CDG 3/19/2018 Asset $ 9,440 $ 1,973 $ 11,413 $ 400 $ (15 ) Other 1/15/2018 Asset 2,065 953 3,018 1,271 66 Total $ 11,505 $ 2,926 $ 14,431 $ 1,671 $ 51 Acquisition-related costs recorded within administrative expenses on the Condensed Consolidated Statements of Operations and Comprehensive Income amounted to $0.6 million and $0.5 million for the three months ended March 31, 2019 and 2018, respectively. The goodwill 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 approximately $2.0 million of goodwill for tax purposes as a result of 2019 acquisitions. Purchase Price Allocations The estimated fair values of the assets acquired and liabilities assumed for the acquisitions, as well as total purchase prices and cash paid, approximated the following (in thousands): As of March 31, 2019 As of March 31, 2018 1st State CDG Other Total Estimated fair values: Accounts receivable $  $ 1,731 $  $ 1,731 Inventories 291 514 75 589 Other current assets  28 12 40 Property and equipment 989 933 517 1,450 Intangibles 3,382 3,711 1,675 5,386 Goodwill 1,882 4,898 764 5,662 Other non-current assets  36  36 Accounts payable and other current liabilities (39 ) (438 ) (25 ) (463 ) Fair value of assets acquired and purchase price 6,505 11,413 3,018 14,431 Less seller obligations 1,380 1,973 953 2,926 Cash paid $ 5,125 $ 9,440 $ 2,065 $ 11,505 Contingent consideration is included as seller obligations in the above table or within fair value of assets acquired if subsequently paid during the period presented. These contingent payments consist primarily of earnouts based on performance that are recorded at fair value at the time of acquisition, and/or non-complete agreements and amounts based on working capital calculations. When these payments are expected to be made over one year from the acquisition date, the contingent consideration is discounted to net present value using our weighted average cost of capital (WACC), when appropriate. Further adjustments to the allocation for each acquisition still under its measurement period are expected as third-party and internal valuations are finalized, certain tax aspects of the transaction are completed and customary post-closing reviews are concluded during the measurement period attributable to each individual business combination. As a result, insignificant adjustments to the fair value of assets acquired, and in some cases total purchase price, have been made to certain business combinations since the date of acquisition and future adjustments may be made through the end of each measurement period. Goodwill and intangibles per the above table do not agree to the total gross increases of these assets as shown in Note 5, Goodwill and Intangibles, during each of the three months ended March 31, 2019 and 2018 due to minor adjustments to goodwill for the allocation of certain acquisitions still under measurement as well as other immaterial intangible assets added during the ordinary course of business. In addition, goodwill and intangibles increased during each of the three months ended March 31, 2019 and 2018 due to small tuck-in acquisitions merged into existing operations that do not appear in the above table as discussed above. Estimates of acquired intangible assets related to the acquisitions are as follows (in thousands): For the three months ended March 31, 2019 2018 Acquired intangibles assets Estimated Fair Value Weighted Average Estimated Useful Life (yrs.) Estimated Fair Value Weighted Average Estimated Useful Life (yrs.) Customer relationships $ 2,100 8 $ 3,441 8 Trademarks and trade names 999 15 1,695 15 Non-competition agreements 283 5 250 5 Pro Forma Information The unaudited pro forma information for the combined results of the Company has been prepared as if the 2019 acquisitions had taken place on January 1, 2018 and the 2018 acquisitions had taken place on January 1, 2017. The unaudited pro forma information is not necessarily indicative of the results that we would have achieved had the transactions actually taken place on January 1, 2018 and 2017, respectively, and the unaudited pro forma information does not purport to be indicative of future financial operating results (in thousands, except per share data): Unaudited pro forma for the three months ended March 31, 2019 2018 Net revenue $ 344,397 $ 322,666 Net income 8,793 7,478 Basic and diluted net income per share 0.30 0.24 Unaudited pro forma net income reflects additional intangible asset amortization expense of $64 thousand and $1.2 million for the three months ended March 31, 2019 and 2018, respectively, as well as additional income tax (benefit) expense of ($ 16 ) thousand and $0.4 million for the three months ended March 31, 2019 and 2018, respectively, that would have been recorded had the 2019 acquisitions taken place on January 1, 2018 and the 2018 acquisitions taken place on January 1, 2017.
