1. Organization and Basis of Presentation Brigham Minerals, Inc. (Brigham Minerals) is a Delaware corporation formed in June 2018 for the purpose of completing an initial public offering (the IPO) and related transactions. In April 2019, Brigham Minerals completed the IPO of 16,675,000 shares of Class A common stock. As a result of the IPO and certain reorganization transactions, Brigham Minerals became a holding company whose sole material asset consists of an ownership interest in Brigham Minerals Holdings, LLC (Brigham LLC), which wholly owns Brigham Resources, LLC (Brigham Resources or the Predecessor). Brigham Resources wholly owns Brigham Minerals, LLC and Rearden Minerals, LLC (collectively, the Minerals Subsidiaries), which own all of Brigham Resources operating assets. The Minerals Subsidiaries acquire and actively manage a portfolio of mineral and royalty interests located in seven states in the continental U.S., including all of the major onshore producing basins. In connection with the IPO, Brigham Minerals became the sole managing member of Brigham LLC and is responsible for all operational, management and administrative decisions relating to Brigham LLCs business. References to we, us and our mean Brigham Minerals. The accompanying consolidated and combined financial statements of Brigham Minerals have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The consolidated and combined financial statements reflect all normal recurring adjustments that, in the opinion of management, are necessary for a fair presentation. All significant intercompany transactions and balances have been eliminated upon consolidation and combination. Brigham Resources operates in one segment: oil and natural gas exploration and production. Brigham Resources has historically owned and operated two distinct lines of business through its subsidiaries:  the Minerals Business through the Minerals Subsidiaries; and  an upstream oil and gas exploration and production business (the Upstream Business) in the Southern Delaware Basin of West Texas (including interests in certain related gathering systems) through Brigham Resources Operating, LLC (Brigham Operating). In February 2017, Brigham Operating completed the sale of substantially all of its oil and natural gas properties to an unrelated third-party purchaser, following which Brigham Operatings only material assets have consisted of an ownership interest in Oryx Southern Delaware Holdings, LLC (Oryx), an entity that operates a crude oil gathering system located in the Southern Delaware Basin. Brigham Resources plans to distribute to its members or their affiliates 100% of the equity interests in Brigham Operating. Subsequent to such distribution Brigham Resources will no longer have any direct or indirect ownership interest in Brigham Operating. Accordingly, the accompanying consolidated financial statements of Brigham Resources exclude the assets, liabilities and results of operations of Brigham Operating. Upon the completion of the IPO and associated reorganization, Brigham Minerals indirectly owned an approximate 43.3% interest of Brigham Resources and 100% of the voting rights, and as such, consolidated the results of operations of Brigham Resources. The IPO and associated reorganization was a transaction that lacked substance, and as such, Brigham Resources was consolidated at historical carrying values. In order to furnish comparative financial information, the historical financial statements and related notes of Brigham Minerals for periods prior to the IPO have been retrospectively revised to include the combined historical financial information of both Brigham Resources (at historical carrying values) and Brigham Minerals, taking into account state and federal income taxes and liabilities associated with Brigham Minerals. All intercompany transactions between Brigham Minerals and Brigham Resources have been eliminated. Because Brigham Minerals acquired an interest in Brigham Resources as part of certain reorganization transactions in 2018, net income is attributable to stockholders of Brigham Minerals in addition to our Predecessor beginning in 2018. Subsequent to the issuance of our December 31, 2017 consolidated financial statements, we corrected the amount of equity securities distributed, included in the supplemental disclosure of non-cash activity, from $37,988 to $20,092 (in thousands) for the year ended December 31, 2017. Additionally, we corrected the presentation of gains and losses on sales of assets, and we included these gains and losses in other operating income for all periods presented. This resulted in a $94.6 million increase to previously reported operating expenses and a corresponding increase to previously reported operating income for the year ended December 31, 2017. These corrections did not impact the previously reported consolidated balance sheet as of December 31, 2017 or consolidated statements of comprehensive income, members equity or cash flows and have been accounted for as immaterial corrections of errors.
