In February 2009, the bank’s collateral arrangement with the FHLB converted from a blanket pledge arrangement to a physical possession arrangement whereby the bank was required to deliver loan documents to the FHLB for the collateral securing advances. In September 2011, the FHLB upgraded the bank from a physical possession collateral arrangement to a listing arrangement. Under a listing arrangement, the bank maintains custody of the loan collateral documentation and is required to submit a monthly file listing loans pledged with certain data fields. At December 31, 2012, there was no maximum borrowing term limit and the bank has a credit line of 20% of total assets.

Subordinated Debentures

In March 2003, we created a wholly-owned statutory trust, CPB Capital Trust I (“Trust I”). Trust I issued $15.0 million in trust preferred securities. The Trust I trust preferred securities bear an interest rate of three-month LIBOR plus 3.25%, and mature on April 7, 2033. The principal assets of Trust I are $15.5 million of the Company’s subordinated debentures with an identical interest rate and maturity as the Trust I trust preferred securities. Trust I issued $0.5 million of common securities to the Company.

In October 2003, we created two wholly-owned statutory trusts, CPB Capital Trust II (“Trust II”) and CPB Statutory Trust III (“Trust III”). Trust II issued $20.0 million in trust preferred securities bearing an interest rate of three-month LIBOR plus 2.85% and maturing on October 7, 2033. The principal assets of Trust II are $20.6 million of the Company’s subordinated debentures with an identical interest rate and maturity as the Trust II trust preferred securities. Trust II issued $0.6 million of common securities to the Company.

Trust III issued $20.0 million in trust preferred securities bearing an interest rate of three-month LIBOR plus 2.85% and maturing on December 17, 2033. The principal assets of Trust III are $20.6 million of the Company’s subordinated debentures with an identical interest rate and maturity as the Trust III trust preferred securities. Trust III issued $0.6 million of common securities to the Company.

In September 2004, we created a wholly-owned statutory trust, CPB Capital Trust IV (“Trust IV”). Trust IV issued $30.0 million in trust preferred securities bearing an interest rate of three-month LIBOR plus 2.45% and maturing on December 15, 2034. The principal assets of Trust IV are $30.9 million of the Company’s subordinated debentures with an identical interest rate and maturity as the Trust IV trust preferred securities. Trust IV issued $0.9 million of common securities to the Company.

In December 2004, we created a wholly-owned statutory trust, CPB Statutory Trust V (“Trust V”). Trust V issued $20.0 million in trust preferred securities bearing an interest rate of three-month LIBOR plus 1.87% and maturing on December 15, 2034. The principal assets of Trust V are $20.6 million of the Company’s subordinated debentures with an identical interest rate and maturity as the Trust V trust preferred securities. Trust V issued $0.6 million of common securities to the Company.

The trust preferred securities, the subordinated debentures that are the assets of Trusts I, II, III, IV and V and the common securities issued by Trusts I, II, III, IV and V are redeemable in whole or in part on any January 7, April 7, July 7, or October 7 on or after April 7, 2008 for Trust I, on or after October 7, 2008 for Trusts II and III, and on or after December 15, 2009 for Trust IV and V, or at any time in whole but not in part within 90 days following the occurrence of certain events. Our obligations with respect to the issuance of the trust preferred securities constitute a full and unconditional guarantee by the Company of each trust’s obligations with respect to its trust preferred securities. Subject to certain exceptions and limitations, we may elect from time to time to defer interest payments on the subordinated debentures, which would result in a deferral of distribution payments on the related trust preferred securities, for up to 20 consecutive quarterly periods without default or penalty.

On August 20, 2009, we began deferring regularly scheduled interest payments on our outstanding junior subordinated debentures relating to our trust preferred securities. The terms of the junior subordinated debentures and the trust documents allow us to defer payments of interest for up to 20 consecutive quarterly periods without default or penalty. During the deferral period, which currently stands at 14 consecutive quarters, the respective trusts will likewise suspend the declaration and payment of dividends on the trust preferred securities. Also during the deferral period, we may not, among other things and with limited exceptions, pay cash dividends on or repurchase our common stock or preferred stock or make any payment on outstanding debt obligations that rank equally with or junior to the junior subordinated debentures. During the deferral period, we will continue to accrue, and reflect in our consolidated financial statements, the deferred interest payments on our junior subordinated debentures. Accrued interest on our outstanding junior subordinated debentures relating to our trust preferred securities was $12.2 million and $8.5 million at December 31, 2012 and 2011, respectively.

On February 25, 2013, the Company notified the trustees for its various outstanding trust preferred securities that it intends to pay all deferred interest on its subordinated debentures and related dividend payments on its trust preferred securities and will resume quarterly payments as of the next, respective interest payment due date for each outstanding trust.
