Acquisition of Central Environmental Services In April 2019, BNN Eastern, LLC ("BNN Eastern"), a newly formed indirect subsidiary of TGE, entered into a Stock Purchase Agreement to acquire all of the outstanding stock of CES Holding Company, Inc., which owns all of the issued and outstanding membership interests of K &amp; H Partners LLC, a company doing business as Central Environmental Services ("CES"). CES Holding Company, Inc. is a C corporation for U.S. federal income tax purposes and is considered a taxable entity for such purposes. CES owns and operates a salt water disposal facility located in the Utica and Marcellus area of Ohio. On May 1, 2019, the acquisition closed for cash consideration of approximately $52 million paid at closing, and the issuance of a 7.65% membership interest in BNN Eastern to one of the sellers in the transaction. In addition, the transaction includes a potential earn out payment to the sellers of approximately $3 million based on the achievement of certain milestones during 2019, which is payable in cash or in additional membership interests in BNN Eastern. The transaction qualifies as an acquisition of a business and is accounted for as a business combination under ASC 805. The following represents the fair value of assets acquired and liabilities assumed: Preliminary Adjustments Final (in thousands) Accounts receivable $ 1,391 $  $ 1,391 Prepayments 67  67 Property, plant and equipment 6,900 4,400 11,300 Intangible asset 35,800 (2,900 ) 32,900 (1) Accounts payable and accrued liabilities (1,518 )  (1,518 ) (2) Deferred tax liability (8,557 ) (189 ) (8,746 ) Net identifiable assets acquired 34,083 1,311 35,394 Goodwill 17,734 (1,311 ) 16,423 Net assets acquired (excluding cash) $ 51,817 $  $ 51,817 (1) The $32.9 million intangible asset acquired represents customer relationships and is amortized on a straight-line basis over a period of 8 years. (2) Includes the estimated fair value of the liability for contingent consideration of $0.7 million . At June 30, 2019, the assets acquired and liabilities assumed in the acquisition were recorded at provisional amounts based on the preliminary purchase price allocation. During the three months ended September 30, 2019, the preliminary purchase price allocation was adjusted to reflect additional information obtained with respect to the property, plant and equipment acquired. The purchase price allocation was considered final as of September 30, 2019. The 7.65% equity interest in BNN Eastern held by noncontrolling interests was recorded at its acquisition date fair value of $3.4 million . The fair value of the noncontrolling interests were determined using a discounted cash flow analysis and adjusted for lack of control. These fair value measurements are based on significant inputs, such as forecasted cash flows and discount rates, that are not observable in the market and thus represent fair value measurements categorized within Level 3 of the fair value hierarchy under ASC 820. The goodwill recognized of $16.4 million is primarily attributed to synergies expected from combining the operations of TGE and CES. All the goodwill was assigned to our Gathering, Processing &amp; Terminalling segment. Actual revenue and net income attributable to TGE from CES of $2.4 million and $0.8 million , respectively, was recognized in the accompanying condensed consolidated statements of income for the three months ended September 30, 2019 . Actual revenue and net income attributable to TGE from CES of $4.5 million and $0.9 million , respectively, was recognized in the accompanying condensed consolidated statements of income for the period from May 1, 2019 to September 30, 2019 . Pro Forma Financial Information Unaudited pro forma revenue and net income attributable to TGE for the three and nine months ended September 30, 2019 and 2018 is presented below as if the acquisition of CES had been completed on January 1, 2018.

Joint Venture with Silver Creek In February 2018, we entered into an agreement with Silver Creek Midstream, LLC ("Silver Creek") to form Iron Horse Pipeline, LLC ("Iron Horse"), which owns the Iron Horse Pipeline. Effective January 1, 2019, the joint venture between us and Silver Creek was expanded through contributions to Powder River Gateway, a newly formed entity. We contributed our 75% membership interest in Iron Horse with a carrying value of $35.6 million , $37 million in cash, and various other assets, including terminal facilities under construction in Guernsey, Wyoming, valued at $86.9 million . Silver Creek contributed the PRE Pipeline and related terminal facilities in Guernsey, Wyoming, as well as their 25% membership interest in Iron Horse. Following the expansion of the joint venture, we own a 51% membership interest in Powder River Gateway and continue to operate the joint venture, while Silver Creek owns a 49% membership interest in Powder River Gateway. As Silver Creek retained certain participating rights with respect to Powder River Gateway, the 51% membership interest does not represent a controlling interest in Powder River Gateway. Accordingly, our investment in Powder River Gateway is accounted for under the equity method of accounting and reported as "Unconsolidated investments" on the condensed consolidated balance sheets.
