LONG‑TERM DEBT

2013 Term Loan and Revolving Credit Facility

On September 30, 2013, we entered into a term loan in the amount of $220 million ("Term Loan") with a $40 million revolving credit line ("Revolving Credit Facility"). Borrowings under the Term Loan and Revolving Credit Facility accrued interest at LIBOR plus 6.25%, subject to a 1% LIBOR floor, and were secured by a first priority lien and security interest in all assets of the Company. Proceeds from the Term Loan were used to pay off 100% of our debt outstanding, including accrued interest, at September 30, 2013, with excess proceeds from the Term Loan and the Revolving Credit Facility used to fund growth and working capital needs. The Term Loan and Revolving Credit Facility were scheduled to mature on September 30, 2019 and September 30, 2018, respectively, with quarterly and monthly payments of principal and interest, respectively.

Under the Term Loan and Revolving Credit Facility we were required to comply, subject to certain exceptions and materiality qualifiers, with certain customary affirmative and negative covenants, including, but not limited to, covenants pertaining to reporting, insurance, collateral maintenance, change of control, transactions with affiliates, distributions, and limitations on additional indebtedness. In addition, the Term Loan and Revolving Credit Facility included a maximum leverage ratio of 3.5x EBITDA (earnings before interest, taxes, depreciation, and amortization) to total debt, which became effective March 31, 2014.

In 2015, given the then near-term economic uncertainty and volatility of commodity prices, we determined that we were likely to be out of compliance with the leverage ratio covenant under the Term Loan and Revolving Credit Facility at the March 31, 2016 test date. Accordingly, the Company and its equity sponsor, Energy Capital Partners ("ECP"), commenced negotiations with the lenders to amend the covenants and leverage ratio in the Term Loan and Revolving Credit Facility. The resulting amendment and waiver agreement was executed on June 8, 2016. Under the terms of the amendment, ECP infused $40.0 million of additional equity into the Company, $10.0 million of which was reserved for working capital, with up to $30.0 million available to repurchase debt. A minority shareholder also infused $0.4 million alongside ECP to prevent dilution. The amendment and waiver also suspended the leverage ratio test until June 30, 2017, and provided us with 30 days to deliver any past-due financial statements.

Gain on Extinguishment of Debt — in connection with the amendment to the Term Loan and Revolving Credit Facility, we initiated an auction process with the lenders to repurchase a portion of debt for a price of $0.80, a 20% discount to par value. The auction settled on June 16, 2016 as the Company repurchased a total amount of $37.5 million of debt for $30.0 million plus $0.5 million in debt extinguishment auction costs, leading to a gain on extinguishment of debt of $7.0 million.

On January 13, 2017, we repaid $75 million of the outstanding balance under the Term Loan and repaid the remaining balance of $13.5 million under the Revolving Credit Facility using a portion of the proceeds from the private placement offering. On March 22, 2017, we retired the $71.8 million remaining balance of the Term Loan, along with accrued interest, using a portion of the proceeds from our IPO. Each of the Term Loan and Revolving Credit Facility were terminated in accordance with their terms upon the repayment of outstanding borrowings.

Equipment Financing

On November 24, 2015, we entered into a 36 months financing arrangement for three hydraulic fracturing units in the amount of $25 million, and a portion of the proceeds were used to pay off the previous manufacturer notes, with the remainder being used for additional liquidity.

On June 30, 2017, we entered into a financing arrangement for the purchase of light vehicles. As of December 31, 2017, the outstanding balance for certain light vehicles purchased under this financing arrangement is $4.7 million.

ABL Credit Facility

On March 22, 2017, we entered into a new revolving credit facility with a $150 million borrowing capacity ("ABL Credit Facility"). Borrowings under the ABL Credit Facility accrue interest based on a three-tier pricing grid tied to availability, and we may elect for loans to be based on either LIBOR or base rate, plus the applicable margin, which ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to 1.25% for base rate loans, with no LIBOR floor. Borrowings under the ABL Credit Facility are secured by a first priority lien and security interest in substantially all assets of the Company. The ABL Credit Facility has a tenor of 5 years and a borrowing base of 85% of eligible accounts receivable less customary reserves. Under this facility we are required to comply, subject to certain exceptions and materiality qualifiers, with certain customary affirmative and negative covenants, including, but not limited to, covenants pertaining to our ability to incur liens, indebtedness, changes in the nature of our business, mergers and other fundamental changes, disposal of assets, investments and restricted payments, amendments to our organizational documents or accounting policies, prepayments of certain debt, dividends, transactions with affiliates, and certain other activities. In addition, the ABL Credit Facility includes a Springing Fixed Charge Coverage Ratio of 1.0x when excess availability is less than the greater of (i) 10% of the lesser of the facility size and the Borrowing Base and (ii) $12.0 million. The ABL has a commitment fee of 0.38%, which reduces to 0.25% if utilization is greater than 50% of the borrowing base.

On February 22, 2018, we entered into an amendment with our lenders to increase the capacity of the ABL Credit Facility. The amendment increased total capacity under the facility from $150 million to $200 million.

The fair values of the ABL Credit Facility, Revolving Credit Facility and equipment financing approximate their carrying values. Our Term Loan was completely retired at December 31, 2017. The estimated fair value of the Term Loan at December 31, 2016 was approximately 89% of its carrying value or $130.6 million compared to $146.8 million carrying value.
