NOTE 10. Long-Term Debt and Financing Arrangements

On July 1, 2017, we entered into a $350 million unsecured credit agreement (the "Credit Agreement"). The Credit Agreement replaces the Amended and Restated Credit Agreement dated December 12, 2013 (“2013 Credit Agreement”). The Company used the Credit Agreement to finance, in part, the Estenson Acquisition.

Borrowings under the Credit Agreement generally bear interest at a variable rate equal to (i) LIBOR plus a specified margin based upon the Borrowers' total net leverage ratio (as defined in the Credit Agreement) (the "Total Net Leverage Ratio"), or (ii) the base rate (which is the highest of (a) the administrative agent's prime rate, (b) the federal funds rate plus 0.50% or (c) the sum of 1% plus one-month LIBOR) plus a specified margin based upon the Total Net Leverage Ratio. The specified margin for Eurodollar loans varies from 100.0 to 200.0 basis points per annum. The specified margin for base rate loans varies from 0.0 to 100.0 basis points per annum. The Borrowers must also pay (1) a commitment fee ranging from 10.0 to 25.0 basis points per annum (based upon the Total Net Leverage Ratio) on the aggregate unused commitments and (2) a letter of credit fee ranging from 100.0 to 200.0 basis points per annum (based upon the Total Net Leverage Ratio) on the undrawn amount of letters of credit.

The Credit Agreement contains various restrictions and covenants, including negative covenants that limit or restrict dividends, indebtedness of subsidiaries, mergers and fundamental changes, asset sales, acquisitions, liens and encumbrances, transactions with affiliates, changes in fiscal year and other matters customarily restricted in such agreements. The Company must maintain a Total Net Leverage Ratio of (a) total funded debt as of such date, minus up to $50.0 million in unrestricted cash and cash equivalents (each as defined in the Credit Agreement) to (b) consolidated EBITDA (as defined in the credit agreement) of not more than 3.00 to 1.00; provided that as of the close of each of the four fiscal quarters occurring after the consummation of a permitted acquisition (as defined in the Credit Agreement) with an aggregate consideration of $150.0 million or more, such ratio shall not be more than 3.25 to 1.00. The Company must maintain an interest coverage ratio of consolidated EBITDA to consolidated cash interest expense of not less than 3.00 to 1.00.

We have standby letters of credit that expire in 2018. As of December 31, 2017, our letters of credit were $20.1 million.

Our unused and available borrowings under our bank revolving line of credit were $284.9 million as of December 31, 2017. Our unused and available borrowings under the 2013 Credit Agreement were $38.2 million as of December 31, 2016. We were in compliance with our debt covenants as of December 31, 2017.

We have entered into various Equipment Notes (“Notes”) for the purchase of tractors, trailers and containers. The Notes are secured by the underlying equipment financed in the agreements.

In 2011, we entered into a lease agreement for 3,126 chassis for a period of 10 years. We are accounting for this lease as a capital lease. Interest on this capital lease obligation is based on interest rates that approximate currently available interest rates; therefore, indebtedness under this capital lease obligation approximates fair value. We paid interest of $0.5 million, $0.6 million and $0.7 million in 2017, 2016 and 2015, respectively, related to this capital lease.

In February 2018, we entered in a secured equipment note for the purchase of 29 tractors and 36 trailers for $5.0 million. The note calls for 60 monthly payments of $91,986 and has a fixed interest rate of 3.56%.
