Goodwill and Intangible Assets Disclosure [Abstract] |
Business Combinations And Goodwill | Business Combinations and Goodwill In May 2019, we acquired a 70% controlling interest in Subsea Technologies Group Limited (“STL”), a subsea engineering firm based in Aberdeen, Scotland, for $5.1 million. The holders of the remaining 30% noncontrolling interest currently have the right to put their shares to us in June 2024. These redeemable noncontrolling interests have been recognized as temporary equity. STL is included in our Well Intervention segment (Note 13) and its revenue and earnings are immaterial to our consolidated results. As a result of the decline in oil prices as well as energy and energy services valuations during the first quarter 2020 due to the ongoing COVID-19 pandemic and the price war among members of the Organization of Petroleum Exporting Countries (“OPEC”) and other non-OPEC producer nations (collectively with OPEC members, “OPEC+”) during the first quarter 2020, we identified that it was more likely than not that the fair value of goodwill associated with our STL acquisition was less than its carrying amount. Based on the result of our goodwill impairment test as of March 31, 2020, we recorded a charge to write off the carrying amount of the goodwill. The fair value of the reporting unit used to determine the impairment was estimated using a discounted cash flow approach. The changes in the carrying amount of goodwill are as follows (in thousands):
| Well Intervention
Balance at December 31, 2019 | $ | 7,157 |
Impairment loss | (6,689) |
Other adjustments (1) | (468) |
Balance at September 30, 2020 | $ | — |
(1)Relates to foreign currency adjustments.
