In March 2018, the Company issued $330.0 million in aggregate principal amount, of 5.00% Fixed-to-Floating Rate Subordinated Notes (“the Notes”) at a public offering price equal to 100% of the aggregate principal amount of the Notes. The Company incurred $3.6 million in debt issuance costs related to the offering during March. The Notes will mature on April 1, 2028 and will bear interest at an initial fixed rate of 5.00% per annum, payable semi-annually in arrears. From and including April 1, 2023 to, but excluding the maturity date or the date of earlier redemption, the interest rate will reset quarterly to an annual interest rate equal to the then-current three month LIBOR rate plus 215 basis points, payable quarterly in arrears. The Notes will be subordinated in right of payment to the payment of the Company’s other existing and future senior indebtedness, including all of its general creditors. The Notes are obligations of Simmons First National Corporation only and are not obligations of, and are not guaranteed by, any of its subsidiaries. During the first half of 2018, the Company used a portion of the net proceeds from the sale of the Notes to repay certain outstanding indebtedness, including the amounts borrowed under the Revolving Credit Agreement (the “Credit Agreement”), certain trust preferred securities, both discussed below, and unsecured debt from correspondent banks. The subordinated notes qualify for Tier 2 capital treatment.

In October 2017, the Company entered into the Credit Agreement with U.S. Bank National Association and executed an unsecured Revolving Credit Note pursuant to which the Company may borrow, prepay and re-borrow up to $75.0 million, the proceeds of which were primarily used to pay off amounts outstanding under a term note assumed with the First Texas acquisition. The Credit Agreement contains customary representations, warranties, and covenants of the Company, including, among other things, covenants that impose various financial ratio requirements. The line of credit available to the Company under the Credit Agreement expires on October 5, 2018, at which time all amounts borrowed, together with applicable interest, fees, and other amounts owed by the Company shall be due and payable.

At June 30, 2018, the Company had $945.0 million of Federal Home Loan Bank (“FHLB”) advances outstanding with original maturities of one year or less.

The Company had total FHLB advances of $1.5 billion at June 30, 2018, with approximately $1.5 billion of additional advances available from the FHLB. The FHLB advances are secured by mortgage loans and investment securities totaling approximately $3.9 billion at June 30, 2018.

The trust preferred securities are tax-advantaged issues that qualified for Tier 1 capital treatment until December 31, 2017, when the Company reached $15 billion in assets. They still qualify for inclusion as Tier 2 capital at June 30, 2018. Distributions on these securities are included in interest expense on long-term debt. Each of the trusts is a statutory business trust organized for the sole purpose of issuing trust securities and investing the proceeds thereof in junior subordinated debentures of the Company, the sole asset of each trust. The preferred securities of each trust represent preferred beneficial interests in the assets of the respective trusts and are subject to mandatory redemption upon payment of the junior subordinated debentures held by the trust. The common securities of each trust are wholly-owned by the Company. Each trust’s ability to pay amounts due on the trust preferred securities is solely dependent upon the Company making payments on the related junior subordinated debentures. The Company’s obligations under the junior subordinated securities and other relevant trust agreements, in aggregate, constitute a full and unconditional guarantee by the Company of each respective trust’s obligations under the trust securities issued by each respective trust.

The Company’s long-term debt includes subordinated debt, notes payable and FHLB advances with an original maturity of greater than one year. Aggregate annual maturities of long-term debt at June 30, 2018, are as follows:



(In thousands)	Year	Annual Maturities

	2019	2,212
