Financing Arrangements

Credit Facility

The Company has a revolving credit facility (the “Credit Facility”) under its Second Amended and Restated Credit Agreement (the “Credit Agreement”) with an initial maximum credit amount of $200.0 million including a swing line facility of an aggregate amount of up to $20.0 million and a letter of credit sub-facility providing for the issuance of letters of credit up to an aggregate amount of $20.0 million. The Company may request additional revolving commitments or incremental term loans thereunder up to an aggregate amount of $100.0 million, subject to certain additional conditions as provided in the Credit Agreement. As of December 31, 2018, the Company had available borrowing capacity of $130.0 million under the Credit Facility.

Principal payments under the Credit Facility are due upon maturity of the facility on July 7, 2022; however, borrowings may be repaid, at the Company’s discretion, in whole or in part at any time, without penalty, subject to required notice periods and compliance with minimum prepayment amounts. Borrowings under the Credit Agreement can either be, at the Company’s election: (i) at an Alternate Base Rate (as defined in the Credit Agreement) plus a spread; or (ii) at a Eurodollar Rate (as defined in the Credit Agreement) plus a spread. The applicable spread is dependent upon the Company’s Adjusted Leverage Ratio (as defined in the Credit Agreement). The Credit Agreement contains conditions, representations and warranties, events of default, and indemnification provisions that are customary for financings of this type, including, but not limited to, a minimum interest coverage ratio, a maximum adjusted leverage ratio, and limitations on incurrence of debt, investments, liens on assets, certain sale and leaseback transactions, transactions with affiliates, mergers, consolidations, purchases and sales of assets, and certain restricted payments. The Company was in compliance with the covenants under the Credit Agreement at December 31, 2018.

Interest Rate Swaps

The Company has a five-year interest rate swap agreement with a $50.0 million notional amount maturing on January 2, 2020. The Company receives floating‑rate interest amounts based on one-month LIBOR in exchange for fixed-rate interest payments of 1.85% over the life of the agreement. The interest rate swap mitigates interest rate risk by effectively converting $50.0 million of borrowings under the Credit Facility from variable‑rate interest to fixed‑rate interest with a per annum rate of 3.10% based on the margin of the Credit Facility as of December 31, 2018. The fair value of the interest rate swap of $0.3 million and $0.1 million was recorded in other long-term assets in the consolidated balance sheet at December 31, 2018 and 2017, respectively.

In June 2017, the Company entered into a forward-starting interest rate swap agreement with a $50.0 million notional amount which will start on January 2, 2020 upon maturity of the current interest rate swap agreement, and mature on June 30, 2022. The Company will receive floating-rate interest amounts based on one-month LIBOR in exchange for fixed-rate interest payments of 1.99% over the life of the agreement. The interest rate swap mitigates interest rate risk by effectively converting $50.0 million of borrowings under the Credit Facility from variable-rate interest to fixed-rate interest with a per annum rate of 3.24% based on the margin of the Credit Facility as of December 31, 2018. The fair value of the interest rate swap of $0.5 million and $0.4 million was recorded in other long-term assets in the consolidated balance sheet at December 31, 2018 and 2017, respectively.

The unrealized gain or loss on the interest rate swap instruments was reported as a component of accumulated other comprehensive loss, net of tax, in stockholders’ equity at December 31, 2018 and 2017, and the change in the unrealized income on the interest rate swaps for the years ended December 31, 2018 and 2017 was reported in other comprehensive income, net of tax, in the consolidated statements of comprehensive income. The interest rate swaps are subject to certain customary provisions that could allow the counterparty to request immediate settlement of the fair value liability or asset upon violation of any or all of the provisions. The Company was in compliance with all provisions of the interest rate swap agreements at December 31, 2018.

Accounts Receivable Securitization Program

The Company’s accounts receivable securitization program was amended and extended in August 2018 to modify certain covenants and conditions and extend the maturity date of the program to October 1, 2021. The program allows for cash proceeds up to $125.0 million to be provided under the program and has an accordion feature allowing the Company to request additional borrowings up to $25.0 million, subject to certain conditions. Under this program, certain subsidiaries of the Company continuously sell a designated pool of trade accounts receivables to a wholly owned subsidiary which, in turn, may borrow funds on a revolving basis. This wholly owned consolidated subsidiary is a separate bankruptcy-remote entity, and its assets would be available only to satisfy the claims related to the lender’s interest in the trade accounts receivables. Borrowings under the accounts receivable securitization program bear interest based upon LIBOR, plus a margin, and an annual facility fee. The securitization agreement contains representations and warranties, affirmative and negative covenants, and events of default that are customary for financings of this type, including a maximum adjusted leverage ratio covenant. The Company repaid $5.0 million of its borrowed amount under the accounts receivable securitization program during the fourth quarter of 2018. As of December 31, 2018 and 2017, $40.0 million and $45.0 million, respectively, was borrowed under the accounts receivable securitization program. The Company was in compliance with the covenants under the accounts receivable securitization program as of December 31, 2018.

The accounts receivable securitization program includes a provision under which the Company may request and the letter of credit issuer may issue standby letters of credit, primarily in support of workers’ compensation and third‑party casualty claims liabilities in various states in which the Company is self‑insured. The outstanding standby letters of credit reduce the availability of borrowings under the program. As of December 31, 2018, standby letters of credit of $16.6 million have been issued under the program, which reduced the available borrowing capacity to $68.4 million.

Letter of Credit Agreements and Surety Bond Programs

As of December 31, 2018 and 2017, the Company had letters of credit outstanding of $17.2 million and $18.3 million, respectively, (including $16.6 million and $17.7 million, respectively, issued under the accounts receivable securitization program). The Company has programs in place with multiple surety companies for the issuance of surety bonds in support of its self-insurance program. As of December 31, 2018 and 2017, surety bonds outstanding related to the self-insurance program totaled $49.1 million and $60.4 million, respectively.

Notes Payable

The Company has financed the purchase of certain revenue equipment, other equipment, and software through promissory note arrangements, including $94.0 million, $84.2 million, and $83.4 million for revenue equipment and software in 2018, 2017, and 2016, respectively.
