Acquisitions The following summarizes our acquisitions during the nine months ended December 31, 2018 : Water Pipeline Company On April 24, 2018, we acquired the remaining 18.375% interest in NGL Water Pipelines, LLC operating in the Delaware Basin portion of the Permian Basin in West Texas for total consideration of approximately $4.0 million . The acquisition of the remaining interest was accounted for as an equity transaction, no gain or loss was recorded, and the carrying value of the noncontrolling interest was adjusted to reflect the change in ownership interest of the subsidiary. As of the date of the transaction, the 18.375% interest had a carrying value of $3.9 million . Saltwater Water Solutions Facilities During the nine months ended December 31, 2018 , we acquired six saltwater disposal facilities (including 15 saltwater disposal wells) for total consideration of approximately $116.0 million . As part of these acquisitions, we recorded customer relationship and favorable contract intangible assets whereby we estimated the value of these intangible assets using the income approach, which uses valuation techniques to convert future amounts (for example, cash flows or earnings) to a single present amount (discounted). The measurement is based on the value indicated by current market expectations about those future amounts. We assumed land leases with a royalty component as part of the acquisition of these facilities. The acquisition method of accounting requires that executory contracts with unfavorable terms relative to market conditions at the acquisition date be recorded as liabilities in the acquisition accounting. We recorded a liability to other noncurrent liabilities of $1.1 million related to these leases due to the royalty terms being deemed unfavorable. We will amortize this liability based on the volumes processed by the facilities. The agreements for these acquisitions contemplate post-closing payments for certain working capital items. We are accounting for these transactions as business combinations. The following table summarizes the preliminary estimates of the fair values as of December 31, 2018 for the assets acquired and liabilities assumed (in thousands): Property, plant and equipment $ 33,202 Goodwill 58,751 Intangible assets 25,124 Other noncurrent liabilities (1,127 ) Fair value of net assets acquired $ 115,950 As of December 31, 2018 , the allocation of the purchase price is considered preliminary as we are continuing to gather additional information to (i) finalize the fair values of the property, plant and equipment and intangible assets and (ii) finalize the calculation of asset retirement obligations. Goodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual assets acquired, net of liabilities assumed. Goodwill represents a premium paid to expand the number of our disposal sites in an oilfield production basin currently serviced by us, thereby enhancing our competitive position as a provider of disposal services in this oilfield production basin. We expect that all of the goodwill will be deductible for federal income tax purposes. The operations of these water solutions facilities have been included in our unaudited condensed consolidated statement of operations since their acquisition date. Our unaudited condensed consolidated statement of operations for the nine months ended December 31, 2018 includes revenues of $9.1 million and operating income of $3.7 million that were generated by the operations of these water solutions facilities. We incurred $0.2 million of transaction costs related to these acquisitions during the nine months ended December 31, 2018 . These amounts are recorded within general and administrative expenses in our unaudited condensed consolidated statement of operations. During the nine months ended December 31, 2018 , we also acquired five saltwater disposal wells for total consideration of $24.1 million , which we are accounting for as an acquisition of assets. Freshwater Water Solutions Facilities During the nine months ended December 31, 2018 , we acquired a ranch and four freshwater facilities (including 27 freshwater wells) and a right-of-way that can be used for pipelines for total consideration of approximately $78.1 million . As part of these acquisitions, we recorded customer relationship and favorable contract intangible assets, whereby we estimated the value of these intangible assets using the income approach, which uses valuation techniques to convert future amounts (for example, cash flows or earnings) to a single present amount (discounted). The measurement is based on the value indicated by current market expectations about those future amounts. A book/tax difference was created as part of one of these acquisitions and as a result, we have recorded a preliminary noncurrent deferred tax liability of $22.4 million (see Note 2 for a further discussion). We recorded a contingent consideration liability within accrued expenses and other payables and other noncurrent liabilities in our unaudited condensed consolidated balance sheet related to future royalty payments due to the seller. We estimated the contingent consideration based on the contracted royalty rate, which is a flat rate per barrel, multiplied by the expected volumes of freshwater sold. This amount was then discounted to present value using our weighted average cost of capital plus a premium representative of the uncertainty associated with the expected volumes. As of the acquisition date, we recorded a contingent liability of $1.8 million . We assumed land leases with a royalty component as part of the acquisition of certain of these facilities. The acquisition method of accounting requires that executory contracts with unfavorable terms relative to market conditions at the acquisition date be recorded as liabilities in the acquisition accounting. We recorded a liability within other noncurrent liabilities of $0.5 million related to these leases due to the royalty terms being deemed unfavorable. We will amortize this liability based on the volumes processed by the facilities. The agreements for these acquisitions contemplate post-closing payments for certain working capital items. We are accounting for these transactions as business combinations. The following table summarizes the preliminary estimates of the fair values as of December 31, 2018 for the assets acquired and liabilities assumed (in thousands): Current assets $ 519 Property, plant and equipment 23,787 Goodwill 7,771 Intangible assets 68,624 Investments in unconsolidated entities 2,060 Current liabilities (173 ) Other noncurrent liabilities (24,527 ) Fair value of net assets acquired $ 78,061 As of December 31, 2018 , the allocation of the purchase price is considered preliminary as we are continuing to gather additional information to (i) finalize the fair values of land, other property, plant and equipment, other intangible assets, including water rights and customer relationships, and the investment in the unconsolidated entity and (ii) calculate additional contingent consideration liabilities. We are also engaging a third party valuation firm to assist us in this effort. The noncurrent deferred tax liability is also considered preliminary and will be finalized once the fair value of the assets acquired has been finalized. Goodwill represents the excess of the consideration paid for the acquired businesses over the fair value of the individual assets acquired, net of liabilities assumed. Goodwill represents a premium paid to expand our service offerings in an oilfield production basin currently serviced by us, thereby enhancing our competitive position as a provider of disposal and other services in this oilfield production basin. We expect that all of the goodwill will be deductible for federal income tax purposes. The operations of these water solutions facilities have been included in our unaudited condensed consolidated statement of operations since their acquisition date. Our unaudited condensed consolidated statement of operations for the nine months ended December 31, 2018 includes revenues of $1.6 million and an operating loss of $0.2 million that were generated by the operations of these water solutions facilities. We incurred $3.7 million of transaction costs related to these acquisitions during the nine months ended December 31, 2018 . These amounts are recorded within general and administrative expenses in our unaudited condensed consolidated statement of operations. During the nine months ended December 31, 2018 , we also acquired an additional ranch (including 18 freshwater wells) for total consideration of $28.4 million , which we are accounting for as an acquisition of assets. Retail Propane Businesses During the three months ended June 30, 2018, we acquired three retail propane businesses for total consideration of approximately $19.1 million . We accounted for these transactions as business combinations. On July 9, 2018, and in conjunction with the sale of the Retail Propane segment (see Note 1 ), we acquired the remaining 40% interest in Atlantic Propane, LLC, which was part of our Retail Propane segment, for total consideration of approximately $12.8 million . The acquisition of the remaining interest was accounted for as an equity transaction, no gain or loss was recorded, and the carrying value of the noncontrolling interest was adjusted to reflect the change in ownership interest of the subsidiary. Atlantic Propane, LLC was included in the sale to Superior (see Note 1 ). The assets and liabilities of these retail propane transactions were included in the sale of virtually all of our Retail Propane segment on July 10, 2018 (see Note 14 ).
