Long-term Debt
Long-term Debt	(4)Long-Term Debt (a)Revolving Credit Facility On November 10, 2014, in connection with the closing of the IPO, the Partnership entered into a revolving credit facility with a syndicate of bank lenders (the “revolving credit facility”). The revolving credit facility initially provided for lender commitments of $1.0 billion and a letter of credit sublimit of $150 million. The revolving credit facility will mature on November 10, 2019. The revolving credit facility is ratably secured by mortgages on substantially all of our properties, including the properties of our restricted subsidiaries, and guarantees from our restricted subsidiaries. The revolving credit facility contains certain covenants including restrictions on indebtedness and distributions, and requirements with respect to leverage and interest coverage ratios. The Partnership was in compliance with all of the financial covenants under the revolving credit facility as of December 31, 2014 and September 30, 2015. 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 three months. Interest is payable at a variable rate based on LIBOR or the base rate, determined by election at the time of borrowing. Commitment fees on the unused portion of the revolving credit facility are due quarterly at rates ranging from 0.25% to 0.375% of the unused facility based on utilization. At December 31, 2014 and September 30, 2015, we had borrowings under the revolving credit facility of zero and $525 million, respectively, with a weighted average interest rate of 1.70% and no letters of credit outstanding at December 31, 2014 or September 30, 2015. On September 23, 2015, aggregate lender commitments under the revolving credit facility increased to $1.5 billion in connection with the Water Acquisition.

The facilities were ratably secured by mortgages on substantially all of Antero’s properties, by a security interest on substantially all of Midstream Operating’s personal property and by guarantees from Antero and its restricted subsidiaries. On November 10, 2014, in connection with the completion of the IPO, the outstanding balance of the Midstream credit facility was repaid out of the proceeds of the IPO, and this facility was assumed by Antero Water. (c)Antero Water Credit Facility On November 10, 2014, in connection with the closing of the IPO, Antero Water assumed the Midstream credit facility under amended terms (the “Water facility”), in order to provide for separate borrowings attributable to Antero’s water handling business. The Water facility was repaid in full and terminated on September 23, 2015, in connection with the Water Acquisition. As of December 31, 2014, Antero Water had a total outstanding balance under the Water facility of $115 million, with a weighted average interest rate of 2.19%.
