GOODWILL AND OTHER INTANGIBLE ASSETS |
NOTE 8—GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill is evaluated for impairment on at least an annual basis, or more frequently if indicators of impairment exist. The annual impairment tests are based on Level 3 inputs (see Note 12). During the first quarter of 2019, the Affirm goodwill was reduced to zero from the crane divestiture and impairment. The $4.4 million of goodwill impairment was based on the expected proceeds from selling and winding down the rest of the Affirm business. Also, in connection with the Company’s segment realignment, the Company reallocated goodwill from reporting units in the 2018 Water Solutions segment to reporting units in the 2019 Water Services and Water Infrastructure segments. The changes in the carrying amounts of goodwill by reportable segment as of June 30, 2019 and December 31, 2018 are as follows: | | | | | | | | | | | | | | | | | | | | | | | | Oilfield | | Water | | Wellsite | | Water | | Water | | | | | | | | | Chemicals | | Solutions | | Services | | Services | | Infrastructure | | Other | | Total | | | (in thousands) | Balance as of December 31, 2017 | | $ | 15,637 | | $ | 245,542 | | $ | 12,242 | | $ | — | | $ | — | | $ | — | | $ | 273,421 | Additions | | | — | | | 982 | | | — | | | — | | | — | | | — | | | 982 | Impairment | | | (12,652) | | | — | | | (5,242) | | | — | | | — | | | — | | | (17,894) | Measurement period adjustments | | | (2,985) | | | 20,277 | | | — | | | — | | | — | | | — | | | 17,292 | Balance as of December 31, 2018 | | | — | | | 266,801 | | | 7,000 | | | — | | | — | | | — | | | 273,801 | Resegmentation | | | — | | | (266,801) | | | (7,000) | | | 186,335 | | | 80,466 | | | 7,000 | | | — | Measurement period adjustments(1) | | | — | | | — | | | — | | | 133 | | | — | | | — | | | 133 | Affirm crane business divestiture | | | — | | | — | | | — | | | — | | | — | | | (2,604) | | | (2,604) | Affirm impairment | | | — | | | — | | | — | | | — | | | — | | | (4,396) | | | (4,396) | Balance as of June 30, 2019 | | $ | — | | $ | — | | $ | — | | $ | 186,468 | | $ | 80,466 | | $ | — | | $ | 266,934 |
