(2)Summary of Significant Accounting Policies

(a) Basis of Presentation

These condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) applicable to interim financial information and should be read in the context of the December 31, 2017 consolidated financial statements and notes thereto for a more complete understanding of the Partnership’s operations, financial position, and accounting policies.  The December 31, 2017 consolidated financial statements have been filed with the SEC in the Partnership’s 2017 Form 10-K.

These unaudited condensed consolidated financial statements of the Partnership have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information, and, accordingly, do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments (consisting of normal and recurring accruals) considered necessary for a fair presentation of the Partnership’s financial position as of December 31, 2017 and March 31, 2018, and the results of our operations and cash flows for the three months ended March 31, 2017 and 2018. The Partnership has no items of other comprehensive income; therefore, its net income is equal to its comprehensive income.

Certain costs of doing business incurred by Antero Resources on our behalf have been reflected in the accompanying condensed consolidated financial statements. These costs include general and administrative expenses attributed to us by Antero Resources in exchange for:


business services, such as payroll, accounts payable and facilities management;


corporate services, such as finance and accounting, legal, human resources, investor relations and public and regulatory policy; and


employee compensation, including equity‑based compensation.

Transactions between us and Antero Resources have been identified in the condensed consolidated financial statements (see Note 3—Transactions with Affiliates).

As of the date these condensed consolidated financial statements were filed with the SEC, we completed our evaluation of potential subsequent events for disclosure and no items requiring disclosure were identified, except the declaration of a cash distribution to unitholders, as described in Note 7—Partnership Equity and Distributions.

(b)Revenue Recognition

We provide gathering and compression and water handling and treatment services under fee-based contracts primarily based on throughput or at cost plus a margin. Under these arrangements, we receive fees for gathering oil and gas products, compression services, and water handling and treatment services. The revenue we earn from these arrangements is directly related to (1) in the case of natural gas gathering and compression, the volumes of metered natural gas that we gather, compress and deliver to natural gas compression sites or other transmission delivery points, (2) in the case of oil gathering, the volumes of metered oil that we gather and deliver to other transmission delivery points, (3) in the case of fresh water services, the quantities of fresh water delivered to our customers for use in their well completion operations, (4) in the case of wastewater treatment services, the quantities of wastewater treated for our customers, or (5) in the case of flowback and produced water, the third party out-of-pocket costs we incur plus 3%. We recognize revenue when we satisfy a performance obligation by delivering a service to a customer.

(c) Use of Estimates

The preparation of the condensed consolidated financial statements and notes in conformity with GAAP requires that management formulate estimates and assumptions that affect revenues, expenses, assets, liabilities and the disclosure of contingent assets and liabilities. Items subject to estimates and assumptions include the useful lives of property and equipment and valuation of accrued liabilities, among others. Although management believes these estimates are reasonable, actual results could differ from these estimates.

(d)Cash and Cash Equivalents

We consider all liquid investments purchased with an initial maturity of three months or less to be cash equivalents. The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these instruments.

(e)Property and Equipment

Property and equipment primarily consists of gathering pipelines, compressor stations, fresh water delivery pipelines and facilities, and our wastewater treatment facility and related landfill to be used for the disposal of waste therefrom, stated at historical cost less accumulated depreciation and amortization. We capitalize construction-related direct labor and material costs. We also capitalize interest on capital costs during the construction phase of the water treatment facility, which is currently undergoing testing and commissioning. We capitalized interest of $3 million for each of the three months ended March 31, 2017 and 2018. Net operating expenses incurred during commissioning are capitalized. Maintenance and repair costs are expensed as incurred.

Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives and salvage values of assets. The depreciation of fixed assets recorded under capital lease agreements is included in depreciation expense. Uncertainties that may impact these estimates of useful lives include, among others, changes in laws and regulations relating to environmental matters, including air and water quality, restoration and abandonment requirements, economic conditions, and supply and demand for our services in the areas in which we operate. When assets are placed into service, management makes estimates with respect to useful lives and salvage values that management believes are reasonable. However, subsequent events could cause a change in estimates, thereby impacting future depreciation amounts.

Amortization of landfill airspace consists of the amortization of landfill capital costs, including those that have been incurred and capitalized and estimated future costs for landfill development and construction, as well as the amortization of asset retirement costs arising from landfill final capping, closure, and post-closure obligations. Amortization expense is recorded on a units-of-consumption basis, applying cost as a rate per-cubic yard. The rate per-cubic yard is calculated by dividing each component of the amortizable basis of the landfill by the number of cubic yards needed to fill the corresponding asset’s airspace. Landfill capital costs and closure and post-closure asset retirement costs are generally incurred to support the operation of the landfill over its entire operating life and are, therefore, amortized on a per-cubic yard basis using a landfill’s total airspace capacity. Estimates of disposal capacity and future development costs are created using input from independent engineers and internal technical teams and are reviewed at least annually. However, subsequent events could cause a change in estimates, thereby impacting future amortization amounts.

(1) Amortization of landfill costs is recorded over the life of the landfill on a units-of-consumption basis.

(2) Construction-in-progress includes $319 million for the construction of the wastewater treatment facility, which is currently undergoing testing and commissioning.


(f) Asset Retirement Obligations

In December 2017, we completed the construction of a landfill site to be used for the disposal of waste from our wastewater treatment facility. The landfill began accepting waste in January 2018. Our asset retirement obligations relate to our obligation to close, maintain, and monitor landfill cells and support facilities. After an entire landfill has reached capacity and is certified closed, we must continue to maintain and monitor the landfill for a post-closure period, which generally extends 30 years. We record the fair value of our landfill retirement obligations as a liability in the period in which the regulatory obligation to retire a specific asset is triggered. For our individual landfill cells, the required closure and post-closure obligations under the terms of our permits and our intended operation of the landfill cell are triggered and recorded when the cell is placed into service and waste is initially disposed in the landfill cell. The fair value is based on the total estimated costs to close the landfill cell and perform post-closure activities once the landfill cell has reached capacity and is no longer accepting waste. Retirement obligations are increased each year to reflect the passage of time by accreting the balance at the weighted average credit-adjusted risk-free rate that is used to calculate the recorded liability, with accretion charged to direct costs. Actual cash expenditures to perform closure and post-closure activities reduce the retirement obligation liabilities as incurred. After initial measurement, asset retirement obligations are adjusted at the end of each period to reflect changes, if any, in the estimated future cash flows underlying the obligation. Landfill retirement assets are capitalized as the related retirement obligations are incurred, and are amortized on a units-of-consumption basis as the disposal capacity is consumed.

We are under no legal obligations, neither contractually nor under the doctrine of promissory estoppel, to restore or dismantle our gathering pipelines, compressor stations, water delivery pipelines and facilities and water treatment facility upon abandonment. Our gathering pipelines, compressor stations, fresh water delivery pipelines and facilities and water treatment facility have an indeterminate life, if properly maintained. Accordingly, we are not able to make a reasonable estimate of when future dismantlement and removal dates of our pipelines, compressor stations and facilities will occur. It has been determined by our operational management team that abandoning all other ancillary equipment, outside of the assets stated above, would require minimal costs

(g) Equity‑Based Compensation

Our condensed consolidated financial statements reflect various equity-based compensation awards granted by Antero Resources, as well as compensation expense associated with our own plan. These awards include profits interests awards, restricted stock, stock options, restricted units, and phantom units. In each period, we recognize expense in an amount allocated from Antero Resources, with the offset included in partners’ capital. See Note 3—Transactions with Affiliates for additional information regarding Antero Resources’ allocation of expenses to us.

Under the Antero Midstream Partners LP Long-Term Incentive Plan (“Midstream LTIP”), certain non-employee directors of our general partner and certain officers, employees and consultants of our general partner and its affiliates are eligible to receive awards representing equity interests in the Partnership. An aggregate of 10,000,000 common units may be delivered pursuant to awards under the Midstream LTIP, subject to customary adjustments. For accounting purposes, these units are treated as if they are distributed from us to Antero Resources. Antero Resources recognizes compensation expense for the units awarded to its employees and a portion of that expense is allocated to us. See Note 8—Equity-Based Compensation.

(h)Income Taxes

Our condensed consolidated financial statements do not include a provision for income taxes as we are treated as a partnership for federal and state income tax purposes, with each partner being separately taxed on its distributive share of our items of income, gain, loss, or deduction.

(i)Fair Value Measures

The Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, clarifies the definition of fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. This guidance also relates to all nonfinancial assets and liabilities that are not recognized or disclosed on a recurring basis (e.g., the initial recognition of asset retirement obligations and impairments of long‑lived assets). The fair value is the price that we estimate would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy is used to prioritize inputs to valuation techniques used to estimate fair value. An asset or liability subject to the fair value requirements is categorized within the hierarchy based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. The highest priority (Level 1) is given to unadjusted quoted market prices in active markets for identical assets or liabilities, and the lowest priority (Level 3) is given to unobservable inputs. Level 2 inputs are data, other than quoted prices included within Level 1, that are observable for the asset or liability, either directly or indirectly.

The carrying values on our balance sheet of our cash and cash equivalents, accounts receivable—Antero Resources, accounts receivable—third party, prepaid expenses, other assets, accounts payable, accounts payable—Antero Resources, accrued liabilities, other current liabilities, other liabilities and the revolving credit facility approximate fair values due to their short-term maturities.

(j) Investments in Unconsolidated Affiliates

The Partnership uses the equity method to account for its investments in companies if the investment provides the Partnership with the ability to exercise significant influence over, but not control, the operating and financial policies of the investee. The Partnership’s consolidated net income includes the Partnership’s proportionate share of the net income or loss of such companies. The Partnership’s judgment regarding the level of influence over each equity method investee includes considering key factors such as the Partnership’s ownership interest, representation on the board of directors and participation in policy-making decisions of the investee and material intercompany transactions. See Note 13–Equity Method Investments.

(k) Adoption of New Accounting Principle

On May 28, 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in GAAP when it became effective and was incorporated into GAAP as Accounting Standards Codification (“ASC”) Topic 606.  The new standard became effective for us on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. We have elected the cumulative effect method. The adoption of ASU 2014-09 did not have a material impact on our financial results. For additional information, see Note 4—Revenue.

(l) Recently Issued Accounting Standard

On February 25, 2016, the FASB issued ASU No. 2016-02, Leases, which requires all leasing arrangements to be presented in the balance sheet as liabilities along with a corresponding asset. The ASU will replace most existing leases guidance in GAAP when it becomes effective.  The new standard becomes effective for us on January 1, 2019.  Although early application is permitted, we do not plan to early adopt the ASU.  The standard requires the use of the modified retrospective transition method.  We are evaluating the effect that ASU 2016-02 will have on our consolidated financial statements and related disclosures. We are evaluating the standard’s applicability to our various contractual arrangements with Antero Resources and have tentatively concluded that the application of the ASU to our contractual arrangements with Antero Resources could be subject to differing interpretations. The accounting treatment for these arrangements under the ASU could include (i) the recognition of our Antero contracts as leases under the ASU, (ii) characterization of our servicing revenues from gathering, compression, and water handling and treatment as revenues from leasing or financing, and (iii) derecognition of assets on our balance sheet that are used to provide services under contracts containing variable payment terms. Other interpretations and applications of the standard are also possible. We continue to monitor relevant industry guidance regarding implementation of ASU 2016-02 and will adjust our implementation of the standard as necessary.  We believe that adoption of the standard will not impact our operational strategies, growth prospects, or cash flow.
