| Basis of Presentation | Note 2. Basis of Presentation Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The accompanying consolidated financial statements at June 30, 2020 and December 31, 2019 and for the three and six months ended June 30, 2020 and 2019 contain all normally recurring adjustments considered necessary for a fair presentation of our financial position, results of operations, cash flows and equity for such periods. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020 . We have no items of other comprehensive income; therefore, our net income is identical to our comprehensive income. Consolidation Our consolidated financial statements include our accounts, the accounts of subsidiaries which the Partnership wholly owns and the accounts of subsidiaries in which the Partnership has partial ownership. Variable Interest Entities Our consolidated financial statements include the accounts of Black Diamond, which we control. We have determined that the partners with equity at risk in Black Diamond lack the authority, through voting rights or similar rights, to direct the activities that most significantly impact their economic performance. Therefore, Black Diamond is considered a variable interest entity. Through our majority representation on the Black Diamond board of directors as well as our responsibility as operator of the Black Diamond system, we have the authority to direct the activities that most significantly affect economic performance and the obligation to absorb losses or the right to receive benefits that could be potentially significant to us. Therefore, we are considered the primary beneficiary and consolidate Black Diamond in our financial statements. Financial statement activity associated with Black Diamond is captured within the Gathering Systems and the Investments in Midstream Entities reportable segments. See Note 7. Segment Information . Drop-Down and Simplification Transaction On November 14, 2019, we entered into a Contribution, Conveyance, Assumption and Simplification Agreement with Noble. Pursuant to such agreement, we acquired (i) the remaining 60% limited partner interest in Blanco River DevCo LP, (ii) the remaining 75% limited partner interest in Green River DevCo LP, (iii) the remaining 75% limited partner interest in San Juan River DevCo LP and (iv) all of the issued and outstanding limited liability company interests of NBL Midstream Holdings LLC (“NBL Holdings”). Additionally, all of the Incentive Distribution Rights (“IDRs”) were converted into common units representing limited partner interests in the Partnership (“Common Units”). The acquisition of the interests and conversion of the IDRs are collectively referred to as the “Drop-Down and Simplification Transaction.” The total consideration paid by the Partnership for the Drop-Down and Simplification Transaction was $1.6 billion , which consisted of $670 million in cash and 38,455,018 Common Units issued to Noble. The Drop-Down and Simplification Transaction represented a transaction between entities under common control. Prior to the acquisition of the remaining limited partner interests in Blanco River DevCo LP, Green River DevCo LP and San Juan River DevCo LP, the interests were reflected as noncontrolling interests in the Partnership’s consolidated financial statements. As we acquired additional interests in already-consolidated entities, the acquisition of these interests did not result in a change in reporting entity, as defined under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 805, Business Combinations. Therefore, results of operations related to these entities are accounted for on a prospective basis. Conversely, the acquisition of all of the issued and outstanding limited liability company interests of NBL Holdings is characterized as a change in reporting entity, as defined under FASB Accounting Standards Codification Topic 805, Business Combinations, as this entity previously had not been consolidated by us. Therefore, results of operations related to NBL Holdings have been accounted for on a retrospective basis. Our financial information has been recast to include the historical results of NBL Holdings for the three and six months ended June 30, 2019 . The financial statements of NBL Holdings for the period prior to the Drop-Down and Simplification Transaction have been prepared from the separate records maintained by Noble and may not necessarily be indicative of the results of operations had these entities operated on a consolidated basis during those periods. Because a direct ownership relationship did not exist among the Partnership and NBL Holdings prior to the Drop-Down and Simplification Transaction, the net investment in NBL Holdings is shown as Parent Net Investment, in lieu of partners’ equity, in the accompanying Consolidated Statement of Changes in Equity for periods prior to the Drop-Down and Simplification Transaction. Equity Method of Accounting We use the equity method of accounting for investments in entities that we do not control but over which we exert significant influence. For certain entities, we serve as the operator and exert significant influence over the day-to-day operations. For other entities, we do not serve as the operator; however, our voting position on management committees or the board of directors allows us to exert significant influence over decisions regarding capital investments, budgets, turnarounds, maintenance, monetization decisions and other project matters. Under the equity method of accounting, initially we record the investment at our cost. Differences in the cost, or basis, of the investment and the net asset value of the investee will be amortized into earnings over the remaining useful life of the underlying assets. See Note 6. Investments . Cost Method of Accounting We use the cost method of accounting for our 3.33% interest in White Cliffs Pipeline L.L.C. (“White Cliffs”) as we have virtually no influence over its operations and financial policies. Under the cost method of accounting, we recognize cash distributions from White Cliffs as investment income in our consolidated statements of operations to the extent there is net income and record cash distributions in excess of our ratable share of earnings as return of investment. See Note 6. Investments . Redeemable Noncontrolling Interest Our redeemable noncontrolling interest is related to the preferred equity issuance by one of our subsidiaries. We can redeem the preferred equity in whole or in part at any time for cash at a predetermined redemption price. The predetermined redemption price is the greater of (i) an amount necessary to achieve a 12% internal rate of return or (ii) an amount necessary to achieve a 1.375x multiple on invested capital. GIP CAPS Dos Rios Holding Partnership, L.P. (“GIP”) can request redemption of the preferred equity on or after March 25, 2025. As GIP’s redemption right is outside of our control, the preferred equity is not considered to be a component of equity on the consolidated balance sheet, and is reported as mezzanine equity on the consolidated balance sheet. In addition, because the preferred equity was issued by a subsidiary of the Partnership and is held by a third party, it is considered a redeemable noncontrolling interest. The preferred equity was recorded initially at fair value on the issuance date. Subsequent to issuance, we accrete changes in the redemption value of the preferred equity from the date of issuance to GIP’s earliest redemption date. The preferred equity is perpetual and has a 6.5% annual dividend rate, payable quarterly in cash, with the ability to accrue unpaid dividends during the first two years following the closing. During any quarter in which a dividend is accrued, the accreted value of the preferred equity will be increased by the accrued but unpaid dividend (i.e., a paid-in-kind dividend). Accretion during the three and six months ended June 30, 2020 was approximately $3.4 million and $6.6 million , respectively. Noncontrolling Interests We present our consolidated financial statements with a noncontrolling interest section representing Greenfield Member’s ownership of Black Diamond and Noble’s retained ownership in the Gunnison River DevCo LP. Segment Information Accounting policies for reportable segments are the same as those described in this footnote. Transfers between segments are accounted for at market value. We do not consider interest income and expense or income tax benefit or expense in our evaluation of the performance of reportable segments. See Note 7. Segment Information . Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make a number of estimates and assumptions relating to the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management evaluates estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic and commodity price environment. The current commodity price, supply and demand environment coupled with the novel coronavirus (“COVID-19”) pandemic contributed to an unusually high degree of uncertainty in our estimates this quarter and have increased the likelihood that actual results could differ significantly from those estimates. Impairments During second quarter 2020, we performed qualitative impairment assessments over property, plant and equipment, investments, and intangible assets. No impairment indicators were identified and no impairments were recorded. During first quarter 2020, we identified certain impairment indicators including the significant decrease in commodity prices, changes to our customers’ development outlook due to reductions in demand resulting from the novel coronavirus (“COVID-19”) pandemic and excess crude oil and natural gas inventories, and a decrease in our market capitalization. Due to these impairment indicators, we conducted impairment testing of certain of our assets, as follows: Property, Plant and Equipment and Intangible Assets Due to publicly announced changes to our customers’ development outlook within the Delaware Basin and the Black Diamond dedication area, we concluded impairment indicators existed and conducted an undiscounted cash flow test. We developed estimates of future undiscounted cash flows expected in connection with providing midstream services within the dedication areas and compared the estimates to the carrying amount of the assets utilized to provide midstream services. Assumptions used in the estimates include expectations of throughput volumes, future development and capital spending plans. Based upon the results of the undiscounted cash flow test, we concluded that the carrying amount of the assets were recoverable and no impairment was recorded. Goodwill All of our goodwill was assigned to the Black Diamond reporting unit within the Gathering Systems reportable segment. We performed a qualitative assessment and concluded it was more likely than not that the fair value of the Black Diamond reporting unit was less than its carrying value. We then performed a fair value assessment using the income approach. Our estimate of fair value required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions for operating and development costs as well as taking into account changes and uncertainties in our customers’ development outlook. Based on these assessments, we concluded that our goodwill was fully impaired and recorded a non-cash charge of $109.7 million in March 2020. Equity Method Investments We consider our equity method investments to be essential components of our business and necessary and integral elements of our value chain in support of our operations. We considered whether any facts or circumstances suggested that our equity method investments were impaired on an other-than-temporary basis and concluded that the carrying values of our equity method investments were not impaired. Intangible Assets Our intangible asset accumulated amortization totaled approximately $78.0 million and $61.9 million as of June 30, 2020 and December 31, 2019 , respectively. Intangible asset amortization expense totaled approximately $8.1 million for the three months ended June 30, 2020 and 2019 and $16.1 million and $16.0 million for the six months ended June 30, 2020 and 2019 , respectively. Loan to Equity Method Investee On April 2, 2020, we entered into a loan agreement with EPIC Y-Grade. In accordance with the loan agreement, we loaned $22.5 million to EPIC Y-Grade, to be used for construction and working capital purposes. The maturity date of the loan is December 15, 2023. As the loan does not represent an in-substance capital contribution, it is recorded within other noncurrent assets in our consolidated balance sheets. The loan bears interest at a rate equal to applicable margins plus the London Interbank Offered Rate (“LIBOR”), or alternate base rate. EPIC Y-Grade has the option to defer payment of interest (“PIK Interest”) for a 12-month period commencing on April 2, 2020. All PIK Interest is added to the outstanding principal amount of the loan and shall be paid on the maturity date. The loan plus accrued PIK Interest totaled $23.1 million at June 30, 2020. We recorded an allowance for expected credit losses of $1.3 million that is recorded within other non-operating expense in our consolidated statement of operations. The carrying amount of the loan, net of the allowance for expected credit losses, approximates fair value as a portion of the interest rate is variable and reflective of market rates. Tax Provision We are not a taxable entity for United States federal income tax purposes or for the majority of states that impose an income tax. Taxes are generally borne by our partners through the allocation of taxable income and we do not record deferred taxes related to the aggregate difference in the basis of our assets for financial and tax reporting purposes. We are subject to a Texas margin tax due to our operations in the Delaware Basin and we recorded a de minimis state tax provision for the three months ended June 30, 2020 and 2019 . For periods prior to the Drop-Down and Simplification Transaction, our consolidated financial statements include a provision for tax expense on income related to the assets contributed to the Partnership. Deferred federal and state income taxes were provided on temporary differences between the financial statement carrying amounts of recognized assets and liabilities and their respective tax bases as if the Partnership filed tax returns as a stand-alone entity. Substantially all of our tax provision for the three months ended June 30, 2019 represents federal income taxes associated with the assets contributed in the Drop-Down and Simplification Transaction. Recently Adopted Accounting Standards Clarifying Certain Accounting Standards Codification (“ASC”) Topics In first quarter 2020, the FASB issued ASU No. 2020-01: Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) , to clarify the interactions between these Topics. The update provides clarifications for entities investing in equity securities accounted for under the ASC 321 measurement alternative and companies that hold certain non-derivative forward contracts and purchased options to acquire equity securities. ASU 2020-01 is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. We early adopted this ASU in first quarter 2020. This adoption did not have a material impact on our financial statements. Recently Issued Accounting Standards LIBOR Reform In first quarter 2020, the FASB issued ASU No. 2020-04 (ASU 2020-04): Reference Rate Reform (Topic 848), which provides optional guidance for a limited period of time to ease the transition from LIBOR to an alternative reference rate. The ASU intends to address certain concerns stakeholders raised relating to accounting for contract modifications and hedge accounting. These optional expedients and exceptions to applying GAAP, assuming certain criteria are met, are allowed through December 31, 2022. We are currently evaluating the provisions of ASU 2020-04 and have not yet determined whether we will elect the optional expedients. We do not expect the transition to an alternative rate to have a significant impact on our business, operations or liquidity. Reconciliation of Total Cash We define total cash as cash, cash equivalents and restricted cash. Our restricted cash is included in other current assets in our consolidated balance sheets. The following table provides a reconciliation of total cash: Six Months Ended June 30, (in thousands) 2020 2019 Cash and Cash Equivalents at Beginning of Period $ 12,676 $ 14,761 Restricted Cash at Beginning of Period (1) 50 951 Cash, Cash Equivalents, and Restricted Cash at Beginning of Period $ 12,726 $ 15,712 Cash and Cash Equivalents at End of Period $ 12,729 $ 11,537 Restricted Cash at End of Period (1) — 50 Cash, Cash Equivalents, and Restricted Cash at End of Period $ 12,729 $ 11,587 (1) Restricted cash represents the amount held as collateral for certain of our letters of credit. Revenue Recognition We recognize revenue at an amount that reflects the consideration to which we expect to be entitled in exchange for transferring goods or services to a customer, using a five-step process, in accordance with ASC 606 – Revenue from Contracts with Customers (ASC 606). Under ASC 606, remaining performance obligations represent the transaction price allocated to performance obligations that are unsatisfied as of June 30, 2020 . A certain fresh water delivery affiliate revenue agreement contains a minimum volume commitment for the delivery of fresh water for a fixed fee per barrel with annual percentage escalations.
