In September 2017, Frontier used proceeds from Term Loan B (see definition and note discussion below) to retire $24 million of 8.500% Notes due 2020, $10 million of 9.250% Notes due 2021, $6 million of 7.125% Notes due 2019, and $5 million of 8.125% Notes due 2018. Frontier recorded a gain of $1 million driven primarily by discounts on the retirement of the notes. On April 17, 2017, Frontier used cash available on hand to retire $210 million of 8.25% Senior Notes that matured on such date.

In June 2017, Frontier used cash proceeds from Term Loan B (see definition and note discussion below) to retire $763 million of 8.875% Notes due 2020 and $527 million of 8.500% Notes due 2020. Frontier recorded a loss on early extinguishment of debt of $90 million driven by premiums paid to retire the notes and unamortized original issuance costs.

On February 27, 2017, Frontier entered into a first amended and restated credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, pursuant to which Frontier combined its revolving credit agreement, dated as of June 2, 2014, and its term loan credit agreement, dated as of August 12, 2015. Under the JPM Credit Agreement, as further amended on June 15, 2017 by Increase Joinder No.1 (as so amended, the JPM Credit Agreement), Frontier has a $1,625 million senior secured term loan A facility (the Term Loan A) maturing on March 31, 2021, an $850 million undrawn secured revolving credit facility maturing on February 27, 2022 (the Revolver), and $1,500 million senior secured term loan B facility (the Term Loan B) maturing on June 15, 2024. The maturities of the Term Loan A, the Revolver, and the Term Loan B, in each case if still outstanding, will be accelerated in the following circumstances: (i) if, 91 days before the maturity date of any series of Senior Notes maturing in 2020, 2023 and 2024, more than $500 million in principal amount remains outstanding on such series; or (ii) if, 91 days before the maturity date of the first series of Senior Notes maturing in 2021 or 2022, more than $500 million in principal amount remains outstanding, in the aggregate, on the two series of Senior Notes maturing in such year. The determination of interest rates for each of the facilities under the JPM Credit Agreement is based on margins over the Base Rate (as defined in the JPM Credit Agreement) or over LIBOR, at the election of Frontier. Interest rate margins on the Term Loan A and Revolver (ranging from 0.75% to 1.75% for Base Rate borrowings and 1.75% to 2.75% for LIBOR borrowings) are subject to adjustment based on Frontier’s Total Leverage Ratio (as defined in the JPM Credit Agreement). The interest rate on the Term Loan A as of September 30, 2017 was LIBOR plus 2.75%. Interest rate margins on the Term Loan B (2.75% for Base Rate borrowings and 3.75% for LIBOR borrowings) are not subject to adjustment. The security package under the JPM Credit Agreement includes pledges of the equity interests in certain Frontier subsidiaries and guaranties by certain Frontier subsidiaries. As of September 30, 2017, the revolving credit facility was fully available and no borrowings had been made thereunder. The revolving credit facility is available for general corporate purposes but may not be used to fund dividend payments.

Frontier has two senior secured credit agreements with CoBank, ACB, as administrative agent, lead arranger and a lender, and the other lenders party thereto: the first, for a $350 million senior term loan facility drawn in 2014 (the 2014 CoBank Credit Agreement), matures on October 24, 2019, and the second, for a $315 million senior term loan facility drawn in October 2016 (the 2016 CoBank Credit Agreement), matures on October 12, 2021. We refer to the 2014 CoBank Credit Agreement and the 2016 CoBank Credit Agreement collectively as the CoBank Credit Agreements.

Repayment of the outstanding principal balance under each of the CoBank Credit Agreements is being made in quarterly installments ($9 million, with respect to the 2014 CoBank Credit Agreement, and $8 million, with respect to the 2016 CoBank Credit Agreement), in each case with the remaining outstanding principal balance to be repaid on the applicable maturity date. Borrowings under each of the CoBank Credit Agreements bear interest based on the margins over the Base Rate (as defined in the applicable CoBank Credit Agreement) or over LIBOR, at the election of Frontier.

On March 29, 2017, Frontier amended the 2014 and 2016 CoBank Credit Agreements. The amendments provide that interest rate margins under each of these facilities will range from 0.875% to 3.875% for Base Rate borrowings and 1.875% to 4.875% for LIBOR borrowings, subject to adjustment based on our Total Leverage Ratio, as defined in each credit agreement. The interest rate on each of the facilities as of September 30, 2017 was LIBOR plus 3.875%. In addition, the amendments provide for increases in the maximum Leverage Ratio and expansion of the security package identical to those contained in the JPM Credit Agreement.

As of September 30, 2017, we were in compliance with all of our indenture and credit facility covenants.
