Subordinated Debentures Owed to Trust Subsidiaries Trust preferred securities were issued by the Company’s trust subsidiaries, the common stock of which is wholly-owned by the Company, in conjunction with the Company issuing subordinated debentures to the trust subsidiaries. The terms of the subordinated debentures are the same as the terms of the trust preferred securities. The Company guaranteed the payment of distributions and payments for redemption or liquidation of the trust preferred securities to the extent of funds held by the trust subsidiaries. The obligations of the Company under the subordinated debentures together with the guarantee and other back-up obligations, in the aggregate, constitute a full and unconditional guarantee by the Company of the obligations of all trusts under the trust preferred securities. Note 9. Subordinated Debentures (continued) The trust preferred securities are subject to mandatory redemption upon repayment of the subordinated debentures at their stated maturity date or the earlier redemption in an amount equal to their liquidation amount plus accumulated and unpaid distributions to the date of redemption. Interest distributions are payable quarterly. The Company may defer the payment of interest at any time for a period not exceeding 20 consecutive quarters provided that the deferral period does not extend past the stated maturity. During any such deferral period, distributions on the trust preferred securities will also be deferred and the Company’s ability to pay dividends on its common shares will be restricted. Subject to prior approval by the FRB, the trust preferred securities may be redeemed at par prior to maturity at the Company’s option on or after the redemption date. All of the Company’s trust preferred securities have reached the redemption date and could be redeemed at the Company’s option. The trust preferred securities may also be redeemed at any time in whole (but not in part) for the Trusts in the event of unfavorable changes in laws or regulations that result in 1) subsidiary trusts becoming subject to federal income tax on income received on the subordinated debentures; 2) interest payable by the Company on the subordinated debentures becoming non-deductible for federal tax purposes; 3) the requirement for the trusts to register under the Investment Company Act of 1940, as amended; or 4) loss of the ability to treat the trust preferred securities as Tier 1 capital under the FRB capital adequacy guidelines. For regulatory capital purposes, the FRB has allowed bank holding companies to continue to include trust preferred securities in Tier 1 capital up to a certain limit. Provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank Act”) require the FRB to exclude trust preferred securities from Tier 1 capital, but a permanent grandfather provision applicable to the Company permits bank holding companies with consolidated assets of less than $15 billion to continue counting existing trust preferred securities as Tier 1 capital until they mature, even after the Company’s total assets exceed the $15 billion threshold as a result of organic growth. Once the Company has crossed the $15 billion threshold, any subsequent merger or acquisition would result in disqualification of the Company’s combined trust preferred securities as Tier 1 capital; however, the trust preferred securities would be included in Tier 2 capital. If the Company crosses the $15 billion threshold as a direct result of an acquisition, neither the Company’s nor the acquired institution’s trust preferred securities would continue to qualify as Tier 1 capital, but instead would be included in Tier 2 capital. All of the Company’s trust preferred securities qualified as Tier 1 capital instruments at December 31, 2018. Tier 2 Subordinated Debentures The Company acquired subordinated debentures with the FSB acquisition that qualify as Tier 2 capital under the applicable capital adequacy rules and regulations promulgated by the FRB. The Tier 2 subordinated debentures are not deposits and are not insured by the FDIC or any other government agency. Such obligations are subordinated to the claims of general creditors, are unsecured and are ineligible as collateral. The principal amount is due at maturity and interest distributions are payable quarterly. The Tier 2 subordinated debentures shall not be prepaid prior to the fifth anniversary of the closing date, which is September 30, 2020, except in the event the obligation no longer qualifies as Tier 2 capital (“Tier 2 capital event”) or the interest payable is no longer deductible (“tax event”). Any prepayment made in connection with a Tier 2 capital event or a tax event will be subject to obtaining the prior approval of the FRB. Prepayment on or after the fifth anniversary of the closing date is allowed at any time with notice. For additional information on regulatory capital, see Note 11.
