(2)  Summary of Significant Accounting Policies


(a) Basis of Presentation


These combined consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”).  In the opinion of management, these statements include all adjustments considered necessary for a fair presentation of the Partnership’s financial position as of December 31, 2015 and 2016, and the results of our operations and our cash flows for the years ended December 31, 2014, 2015, and 2016.  The combined consolidated statements of operations and comprehensive income, partners’ capital, and cash flows for 2014 and the combined consolidated balance sheets, and the related combined consolidated statements of operations and comprehensive income, partners’ capital, and cash flows for 2015 have been prepared on a combined basis of accounting. The Partnership has no items of other comprehensive income or loss; therefore, net income is identical to comprehensive income.


Certain costs of doing business incurred by Antero Resources on our behalf have been reflected in the accompanying combined 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 combined consolidated financial statements (see Note 3 – Transactions with Affiliates).


As of the date these combined consolidated financial statements were filed with the SEC, we completed our evaluation of potential subsequent events for disclosure (see Note 14 – Subsequent Events).


(b)Revenue Recognition


We provide gathering and compression and water handling and treatment services under fee-based contracts primarily based on throughput or cost plus 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 and condensate gathering, the volumes of metered oil and condensate 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, or (4) in the case of flowback and produced water, the third party out-of-pocket costs plus 3%. We recognize revenue when all of the following criteria are met: (1) persuasive evidence of an agreement exists, (2) services have been rendered, (3) prices are fixed or determinable and (4) collectability is reasonably assured.


(c)Use of Estimates


The preparation of the combined 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


Prior to September 23, 2015 Antero Water was owned and funded by Antero Resources. Net amounts funded by Antero Resources are reflected as “Deemed distribution to Antero Resources, net” on the accompanying statements of Combined Consolidated Cash Flows.


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 and fresh water delivery pipelines and facilities stated at historical cost less accumulated depreciation. We capitalize construction-related direct labor and material costs. We also capitalize interest on capital costs related to the water treatment facility currently under construction. Maintenance and repair costs are expensed as incurred.


Depreciation 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.


Our investment in property and equipment for the periods presented is as follows (in thousands):

(f)Impairment of Long‑Lived Assets


We evaluate our long‑lived assets for impairment when events or changes in circumstances indicate that the related carrying values of the assets may not be recoverable.  Generally, the basis for making such assessments are undiscounted future cash flow projections for the unit being assessed.  If the carrying values of the assets are deemed not recoverable, the carrying values are reduced to the estimated fair value, which are based on discounted future cash flows or other techniques, as appropriate.  No impairments for such assets have been recorded through December 31, 2016.


(g)Asset Retirement Obligations


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 water treatment facility, currently under construction, upon abandonment. Our gathering pipelines, compressor stations and fresh water delivery pipelines and facilities 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. For the reasons stated above, we have not recorded asset retirement obligations at December 31, 2015 or 2016.


(h)Litigation and Other Contingencies


An accrual is recorded for a loss contingency when its occurrence is probable and damages can be reasonably estimated based on the anticipated most likely outcome or the minimum amount within a range of possible outcomes. We regularly review contingencies to determine the adequacy of our accruals and related disclosures. The ultimate amount of losses, if any, may differ from these estimates.


We accrue losses associated with environmental obligations when such losses are probable and can be reasonably estimated. Accruals for estimated environmental losses are recognized no later than at the time a remediation feasibility study, or an evaluation of response options, is complete. These accruals are adjusted as additional information becomes available or as circumstances change. Future environmental expenditures are not discounted to their present value. Recoveries of environmental costs from other parties are recorded separately as assets at their undiscounted value when receipt of such recoveries is probable.


(i)Equity‑Based Compensation


Our combined 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. For purposes of these combined consolidated financial statements, we recognized as expense in each period 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.


In connection with the Initial Public Offering (“IPO”), Antero Resources Midstream Management LLC and its subsidiaries and affiliates (our “general partner”), adopted the Antero Midstream Partners LP Long-Term Incentive Plan (“Midstream LTIP”), pursuant to which 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 6—Equity-Based Compensation.


(j)Income Taxes


Our combined 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 share of taxable income.


(k)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.


(l)Investment in Unconsolidated Entities


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 11–Equity Method Investment.


(m)Recently Adopted Accounting Pronouncement


On March 30, 2016, the FASB issued ASU No. 2016-09, Stock Compensation–Improvements to Employee Share-Based Payment Accounting.  This standard simplifies or clarifies several aspects of the accounting for equity-based payment awards, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows.  Certain of these changes are required to be applied retrospectively, while other changes are required to be applied prospectively.  The Partnership has elected to early-adopt the standard as of January 1, 2016.


As a result of adopting this standard, we have reclassified cash outflows attributable to tax withholdings on the net settlement of equity-classified awards from operating cash flows to financing cash flows.
