Subordinated Debentures

The Company issued $15.0 million of subordinated debt on October 8, 2015, which qualifies as Tier II regulatory capital. The interest rate on the subordinated debt is 5.50% per annum, fixed for the ten-year term and payable semi-annually on April 15 and October 15 each year. The Company can redeem the subordinated debt at par starting on October 15, 2020 plus accrued and unpaid interest, or earlier if (i) they no longer qualify as Tier II capital for regulatory capital purposes; (ii) a change in law that prevents the Company from deducting interest payable for U.S. federal income tax purposes, or (iii) the Company is required to register as an investment company pursuant to the Investment Company Act of 1940. The subordinated debt is schedule to mature on October 15, 2025.

The Company incurred issuance costs of $536,000 associated with this debt issuance. The Company capitalized these costs and they have been presented within subordinated debentures on the consolidated statements of condition. The Company will amortize the issuance costs over the ten-year term of the subordinated debt. The amortization costs incurred for the year ended December 31, 2017 and 2016 associated with the debt issuance was $54,000, and was recognized as an increase to interest expense within the consolidated statements of income.

In April 2006, the Company formed CCTA, which issued and sold trust preferred securities to the public. The Company received $36.1 million from the issuance of the trust preferred securities in return for junior subordinated debentures issued by the Company to CCTA. The Company owns all of the $1.1 million of outstanding common securities of CCTA. The interest rate of the trust preferred securities was fixed at 6.71% through June 2011 and now floats at the 3 month LIBOR plus 140 basis points. The proceeds from the offering were used to repurchase Company common stock under the tender offer completed in May 2006. The trust preferred securities, which pay interest quarterly at the same rate as the junior subordinated debentures held by CCTA, are mandatorily redeemable on June 30, 2036, or may be redeemed by CCTA at par any time on or after June 30, 2011.

In connection with the acquisition of Union Bankshares Company in 2008, the Company assumed $8.0 million of trust preferred securities, held through a Delaware trust affiliate, UBCT. In 2006, Union Bankshares Company issued an aggregate principal amount of $8.2 million of 30-year junior subordinated deferrable interest debt securities to UBCT. The Company owns all of the $248,000 of outstanding common securities of UBCT. The debt securities obligate the Company to pay interest on their principal sum quarterly in arrears on January 7, April 7, July 7, and October 7 of each year. The interest rate of the trust preferred securities until April 7, 2011 was a blended rate equal to the sum of (1) the product of 50% times the average three-month LIBOR plus 1.42%, plus (2) the product of 50% times 6.4725%. The rate is now the average three-month LIBOR plus 1.42%. The debt securities mature on April 7, 2036, but may be redeemed by the Company, in whole or in part, beginning on April 7, 2011, on any interest payment date. The debt securities may also be redeemed by the Company in whole or in part, within 90 days of the occurrence of certain special redemption events as defined in the Indenture.

CCTA and UBCT are Delaware statutory trusts created for the sole purpose of issuing trust preferred securities and investing the proceeds in junior subordinated debentures of the Company. The junior subordinated debentures are the sole assets of the trusts. The Company is the owner of all of the common securities of CCTA and UBCT and fully and unconditionally guarantees each trust’s securities obligations. In accordance with GAAP, CCTA and UBCT are treated as unconsolidated subsidiaries. The common stock investment in the statutory trusts is included in other assets on the consolidated statements of condition. At December 31, 2017, $43.0 million of the trust preferred securities were included in the Company’s total Tier I capital and amounted to 12.0% of Tier I capital of the Company.

The Company has a notional amount of $43.0 million in interest rate swap agreements on its junior subordinated debentures. Further discussion on the terms and accounting for the interest rate swap agreements is included within Note 18 of the consolidated financial statements.
