¹Acquired junior subordinated debentures were recorded at their acquisition date fair values, which collectively was $5.6 million lower than face value; this amount is being amortized into interest expense over the remaining term to maturity.

Interest on the trust preferred securities is calculated on the basis of 3-month LIBOR plus spread and is re-set quarterly. The trust preferred securities may be redeemed without penalty, upon approval of the Federal Reserve or upon occurrence of certain events affecting their tax or regulatory capital treatment. Distributions on the trust preferred securities are payable quarterly in March, June, September, and December of each year. The proceeds of the offering of trust preferred securities and common equity securities were used by SBCF Capital Trust I and SBCF Statutory Trust II to purchase the $41.2 million junior subordinated deferrable interest notes issued by the Company, and by SBCF Statutory Trust III to purchase the $12.4 million junior subordinated deferrable interest notes issued by the Company, all of which have terms substantially similar to the trust preferred securities.

The Company has the right to defer payments of interest on the notes at any time or from time to time at the Company's election. Interest can be deferred for a period not longer than five years. If the Company elects to defer interest, it may not, with certain exceptions, declare or pay any dividends or distributions on its capital stock or purchase or acquire any of its capital stock. As of December 31, 2019, 2018 and 2017, all interest payments on trust preferred securities were current.

The Company has entered into agreements to guarantee the payments of distributions on the trust preferred securities and payments of redemption of the trust preferred securities. Under these agreements, the Company also agrees, on a subordinated basis, to pay expenses and liabilities of the Trusts other than those arising under the trust preferred securities. The obligations of the Company under the junior subordinated notes, the trust agreement establishing the Trusts, the guarantees and agreements as to expenses and liabilities, in aggregate, constitute a full and conditional guarantee by the Company of the Trusts' obligations under the trust preferred securities.
