Business Acquisitions, Goodwill and Intangible Assets |
Business Acquisitions, Goodwill and Intangible Assets | 3. Business Acquisitions, Goodwill, and Intangible Assets The Company completed one acquisition during the year ended September 30, 2018 for a total consideration of $5.6 million, which was accounted for under the acquisition method. Acquired tangible and intangible assets and liabilities were recognized on the acquisition date based upon their fair values. The determination of fair values of assets and liabilities acquired requires the Company to make estimates and use valuation techniques when market value is not readily available. Transaction costs associated with business acquisitions are expensed as they are incurred. In the fourth quarter of fiscal 2019, the Company recorded a goodwill impairment in its self-perform at-risk construction businesses in its Construction Services segment. Total goodwill impairment was $588.0 million, which was recorded within Impairment of long-lived assets, including goodwill. Fair value was estimated using Level 3 inputs, such as forecasted cash flows, and Level 2 inputs, such as observed non-active market prices. The Company observed a reduction in the estimated fair value of the impaired reporting unit in connection with its continuing review of at-risk construction projects and reduction in its self-perform at-risk construction exposure. The Company identified incremental unfavorable trends in its cash flow expectations compared to prior periods, which resulted in a quantitative impairment assessment. In the second quarter of fiscal 2018, management approved a plan to sell non-core oil and gas assets in North America, included in the Company’s Construction Services segment (the Disposal Group). The Company classified the related assets and liabilities of the Disposal Group as held for sale in the consolidated balance sheet. In the third quarter of fiscal 2018, the Company sold a portion of the assets in the Disposal Group and recognized a $2.1 million loss on disposal. The remaining portion of the Disposal Group was sold in the third quarter of fiscal 2019 and the Company recognized a $7.4 million loss on disposal. The Company recorded losses related to the remeasurement of the Disposal Group based on estimated fair value less costs to sell resulting in total asset impairments of $168.2 million, recorded in Impairment of assets held for sale, including goodwill in the second quarter of fiscal 2018. Fair value was estimated using Level 3 inputs, such as forecasted cash flows, and Level 2 inputs, including bid prices from potential buyers. The changes in the carrying value of goodwill by reportable segment for the fiscal years ended September 30, 2019 and 2018 were as follows: ​
