Senior Revolving Line of Credit

June 30, 2017,

we were authorized to borrow up to

$500

million under a senior revolving line of credit, which is supported by a credit agreement with a group of banks and expires in

September 2020.

This senior credit facility allows us to request an increase in the total commitment by up to

$250

million and to request a

one

-year extension of the maturity date. The applicable interest rate under this agreement is based on either the Prime Rate, the Federal Funds Rate or LIBOR, depending upon the specific type of borrowing, plus an applicable margin based on our credit rating and other fees. At

June 30, 2017,

we had

$95

million outstanding at an average interest rate of

2.33%

under this agreement.

Seni

or Notes

Our senior notes consist of

three

separate issuances. The

first

and

second

issuances are

$250

million of

2.40%

senior notes due

March 2019

and

$250

million of

3.85%

senior notes due

March 2024,

respectively, both of which were issued in

March 2014.

Interest payments under both notes are due semiannually in

March

issued in

August 2015.

Interest payments under this note are due semiannually in

All

three

senior notes were issued by J.B. Hunt Transport Services, Inc., a parent-level holding company with

significant assets or operations. The notes are guaranteed on a full and unconditional basis by a wholly-owned subsidiary. All other subsidiaries of the parent are minor. We registered these offerings and the sale of the notes under the Securities Act of

1933,

pursuant to a shelf registration statement filed in

February 2014.

All notes are unsecured obligations and rank equally with our existing and future senior unsecured debt. We

may

redeem for cash some or all of the notes based on a redemption price set forth in the note indenture. See Note

Derivative Financial Instruments, for terms of interest rate swaps entered into on the

$250

million of

2.40%

senior notes due

March 2019

and the

$350

million of

3.30%

senior notes due

August 2022.

Our financing arrangements require us to maintain certain covenants and financial ratios. We were in compliance with all covenants and financial ratios at

June 30, 2017.
