(14)  Fair Value Measurement

In connection with Antero Resources’ contribution of Antero Water and certain wastewater treatment assets to Antero Midstream Partners in September 2015 (the “Water Acquisition”), Antero Midstream Partners agreed to pay Antero Resources (a) $125 million in cash if the Antero Midstream Partners delivers 176,295,000 barrels or more of fresh water during the period between January 1, 2017 and December 31, 2019 and (b) an additional $125 million in cash if Antero Midstream Partners delivers 219,200,000 barrels or more of fresh water during the period between January 1, 2018 and December 31, 2020.  This contingent consideration liability is valued based on Level 3 inputs related to expected average volumes and weighted average cost of capital.

The following table provides a reconciliation of changes in Level 3 financial liabilities measured at fair value on a recurring basis for the period shown below (in thousands):

The Company accounts for contingent consideration in accordance with applicable accounting guidance pertaining to business combinations.  Antero Midstream Partners is contractually obligated to pay Antero Resources contingent consideration in connection with the Water Acquisition, and therefore recorded this contingent consideration liability at the time of the Water Acquisition.  The Company updates its assumptions each reporting period based on new developments and adjusts such amounts to fair value based on revised assumptions, if applicable, until such consideration is satisfied through payment upon achievement of the specified objectives or it is eliminated upon failure to achieve the specified objectives.

As of March 31, 2019,  Antero Midstream Partners expects to pay the entire amount of the contingent consideration for the 176,295,000 barrels or more of fresh water delivered during the period between January 1, 2017 and December 31, 2019, but not for the 219,200,000 barrels or more of fresh water during the period between January 1, 2018 and December 31, 2020 as a result of changes to Antero Resources’ current 2019 budget and long-term outlook.  The fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement within the fair value hierarchy.  The fair value of the contingent consideration liability associated with future milestone payments was based on the risk adjusted present value of the contingent consideration payout.

The carrying values of accounts receivable and accounts payable at December 31, 2018 and March 31, 2019 approximated fair value because of their short-term nature.  The carrying value of the amounts under the Credit Facility at December 31, 2018 and March 31, 2019 approximated fair value because the variable interest rates are reflective of current market conditions.

As of March 31, 2019, the fair value of the Company’s 2024 Notes and 2027 Notes was approximately $655 million and $660 million, respectively, based on Level 2 market data inputs.
