Revolving Unsecured Credit Facility

During the period from January 1, 2018 through October 4, 2018, the Company maintained an unsecured line of credit with a group of U.S. based commercial lenders (the “Credit Facility”) in the amount of $400.0 million, which was scheduled to mature in September 2022. The Credit Facility charged interest, at the Company’s option, at either (1) the prevailing London Interbank Offered Rate (“LIBOR”) (with interest periods of 1 week or 1, 2, 3 or 6 months at the Company’s option) plus a fixed spread of 2.5% or (2) the prevailing prime or base rate plus a fixed spread of 1.5%.

On October 4, 2018, the Company amended and extended the Credit Facility. The total lender commitment under the amended facility increased from $400.0 million to $425.0 million and the term was extended to October 4, 2023. Certain financial covenants in the facility were amended, including an increase to the permitted consolidated leverage ratio from 2.75 to 3.0 times EBITDA adjusted for certain items as defined in the Credit Facility and an increase to the permitted domestic leverage ratio from 3.5 to 4.0 times domestic EBITDA adjusted for certain items as defined in the Credit Facility.

At December 31, 2018, the Company had $295.0 million in outstanding borrowings and $3.2 million in outstanding letters of credit under the Credit Facility, leaving $126.8 million available for future borrowings. The Credit Facility remains unsecured and continues to bear interest, at the Company’s option, at either (1) the prevailing LIBOR (with interest periods of 1 week or 1, 2, 3 or 6 months at the Company’s option) plus a fixed spread of 2.5% or (2) the prevailing prime or base rate plus a fixed spread of 1.5%. The agreement has a LIBOR floor of 0%. Additionally, the Company is required to pay an annual commitment fee of 0.50% on the average daily unused portion of the Credit Facility commitment. The weighted-average interest rate on amounts outstanding under the Credit Facility at December 31, 2018 was 4.94% based on 1 week LIBOR. Under the terms of the Credit Facility, the Company is required to maintain certain financial ratios and comply with certain financial covenants. The Credit Facility also contains customary restrictions on the Company’s ability to incur additional debt, grant liens, make investments, consummate acquisitions and similar negative covenants with customary carve-outs and baskets. The Company was in compliance with the covenants of the Credit Facility as of December 31, 2018. During fiscal 2018, the Company received net proceeds of $188.0 million from borrowings pursuant to the Credit Facility.

Senior Unsecured Notes

On May 30, 2017, the Company issued $300.0 million of 5.375% senior unsecured notes due on June 1, 2024 (the “Notes”), all of which are currently outstanding. Interest on the Notes is payable semi-annually in arrears on June 1 and December 1. The Notes are fully and unconditionally guaranteed on a senior unsecured basis jointly and severally by all of the Company's existing and future domestic subsidiaries that guarantee its revolving unsecured credit facility. The Notes will permit the Company to make restricted payments, such as purchasing shares of its stock and paying cash dividends, in an unlimited amount if, after giving pro forma effect to the incurrence of any indebtedness to make such payment, the Company's consolidated total debt ratio (“Net Debt Ratio”) is less than 2.25 to 1. The Net Debt Ratio is defined generally in the indenture governing the Notes as the ratio of (1) the total consolidated debt of the Company minus cash and cash equivalents of the Company to (2) the Company’s consolidated trailing twelve months EBITDA, as adjusted to exclude certain non-recurring expenses and giving pro forma effect to operations acquired during the measurement period.

The Company used the proceeds from the Notes to repurchase, or otherwise redeem, its previously outstanding $200.0 million, 6.75% senior unsecured notes due 2021 (the “2021 Notes”). As a result, during fiscal 2017, the Company recognized a $14.1 million loss on extinguishment of debt related to the repurchase or redemption of the 2021 Notes.
