Revolving Credit Facility

The Company has a $500 million Asset Based Lending (ABL) Credit Facility, which is collateralized by the accounts receivable and inventory of the Company’s domestic operations. The ABL facility, which matures in February 2022, includes a $400 million revolving credit facility, a letter of credit sub-facility of up to $200 million, and a $100.0 million term loan (Term Loan). The Term Loan has an interest rate of 3.0% plus a LIBOR spread and can be prepaid in increments of $50 million if certain minimum liquidity conditions are satisfied.

The applicable interest rate for revolving credit borrowings under the ABL facility includes interest rate spreads based on available borrowing capacity that range between 1.75% and 2.25% for LIBOR-based borrowings and between 1.0% and 1.5% for base rate borrowings. The ABL facility contains a financial covenant whereby the Company must maintain a fixed charge coverage ratio of not less than 1.00:1.00 after an event of default has occurred and is continuing or if the undrawn availability under the ABL revolving credit portion of the facility is less than the greater of (i) 10% of the then applicable maximum borrowing amount under the revolving credit portion of the ABL and any outstanding Term Loan balance, or (ii) $40.0 million. The Company was in compliance with the fixed charge coverage ratio covenant at March 31, 2018. Additionally, the Company must demonstrate liquidity, as calculated in accordance with the terms of the ABL facility, of at least $700 million on the date that is 91 days prior to January 15, 2021, the maturity date of the 5.95% Senior Notes due 2021, and that such liquidity is available at all times thereafter until the 5.95% Senior Notes due 2021 are paid in full or refinanced. As of March 31, 2018, there were $50.0 million of outstanding borrowings under the revolving portion of the ABL facility, and $42.3 million was utilized to support the issuance of letters of credit. Average revolving credit borrowings under the ABL facility for the first quarters of 2018 and 2017 were $53 million and $4 million, respectively, bearing an average annual interest rate of 3.50% and 3.43%, respectively.
