(a) Antero Midstream Partners Revolving Credit Facility

Antero Midstream Partners, an indirect, wholly owned subsidiary of the Company, as borrower (the “Borrower”), has a senior secured revolving credit facility (the “Credit Facility”) with a consortium of banks. Lender commitments under the Credit Facility are $2.0 billion. At March 31, 2019, the Borrower had borrowings under the Credit Facility of $1.1 billion with a weighted average interest rate of 3.79%. No letters of credit were outstanding at March 31, 2019 under the Credit Facility. The maturity date of the facility is October 26, 2022. The Credit Facility includes fall away covenants and lower interest rates that are triggered if and when the Borrower is assigned an Investment Grade Rating (as defined below).

Under the Credit Facility, “Investment Grade Period” is a period that, as long as no event of default has occurred and the Borrower is in pro forma compliance with the financial covenants under the Credit Facility, commences when the Company elects to give notice to the Administrative Agent that the Borrower has received at least one of either (i) a BBB- or better rating from Standard and Poor’s or (ii) a Baa3 or better from Moody’s (provided that the non-investment grade rating from the other rating agency is at least either Ba1 if Moody’s or BB+ if Standard & Poor’s (an “Investment Grade Rating”)). An Investment Grade Period can end at the Borrower’s election.

During a period that is not an Investment Grade Period, the Credit Facility is ratably secured by mortgages on substantially all of the Borrower’s properties, including the properties of its subsidiaries, and guarantees from its subsidiaries. During an Investment Grade Period, the liens securing the obligations thereunder shall be automatically released (subject to the provisions of the Credit Facility).

The Credit Facility contains certain covenants including restrictions on indebtedness, and requirements with respect to leverage and interest coverage ratios; provided, however, that during an Investment Grade Period, such covenants become less restrictive on the Borrower. The Credit Facility permits distributions to the holders of the Borrower’s equity interests in accordance with the cash distribution policy previously adopted by the board of directors of the general partner of the Borrower, provided that no event of default exists or would be caused thereby, and only to the extent permitted by our organizational documents. The Borrower was in compliance with all of the financial covenants under the Credit Facility as of March 31, 2019.

Principal amounts borrowed are payable on the maturity date with such borrowings bearing interest that is payable quarterly or, in the case of Eurodollar Rate Loans, at the end of the applicable interest period if shorter than six months. Interest is payable at a variable rate based on LIBOR or the base rate, determined by election at the time of borrowing. Interest at the time of borrowing is determined with reference to (i) during any period that is not an Investment Grade Period, the Company’s then-current leverage ratio and (ii) during an Investment Grade Period, with reference to the rating given to the Company by Moody’s or Standard and Poor’s. During an Investment Grade Period, the applicable margin rates are reduced by 25 basis points. Commitment fees on the unused portion of the Credit Facility are due quarterly at rates ranging from 0.25% to 0.375% based on the leverage ratio, during a period that is not an Investment Grade Period, and 0.175% to 0.375% based on the Company’s rating during an Investment Grade Period.
