Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES In order to meet the financing needs of its customers, BancShares has financial instruments with off-balance sheet risk. These financial instruments include commitments to extend credit, standby letters of credit and recourse obligations on mortgage loans sold. These instruments involve elements of credit, interest rate or liquidity risk. Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed expiration dates or other termination clauses and may require payment of fees. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. Established credit standards control the credit-risk exposure associated with these commitments. In some cases, BancShares requires that collateral be pledged to secure the commitment including cash deposits, securities and other assets. At December 31, 2012, and 2011, BancShares had unused commitments totaling $5,467,998 and $5,636,942, respectively. Standby letters of credit are commitments guaranteeing performance of a customer to a third party. Those guarantees are issued primarily to support public and private borrowing arrangements. In order to minimize its exposure, BancShares’ credit policies govern the issuance of standby letters of credit. At December 31, 2012, and 2011, BancShares had standby letters of credit amounting to $63,085 and $57,446, respectively. The credit risk related to the issuance of these letters of credit is essentially the same as that involved in extending loans to clients, and therefore, these letters of credit are collateralized when necessary. Residential mortgage loans are sold with standard representations and warranties relating to documentation and underwriting requirements for the loans. If deficiencies are discovered at any point in the life of the loan, the investor may require BancShares to repurchase the loan. As of December 31, 2012, other liabilities included a reserve of $4,065 for estimated losses arising from the repurchase of loans under those provisions. Residential mortgage loans sold with limited recourse liability represent guarantees to repurchase the loans or pay a fee in the event of nonperformance by the borrower. The recourse period is generally 120 days or less. At December 31, 2012, and 2011, BancShares has sold loans of approximately $205,888 and $207,963, respectively, for which the recourse period had not yet elapsed. Of these loans, $97,706 and $82,167 at December 31, 2012, and 2011, respectively, represent loans that would require repurchase in the event of nonperformance by the borrower. Any loans that are repurchased under the recourse obligation would carry the same credit risk as mortgage loans originated by the company and would be collateralized in the same manner. BancShares has recorded a receivable from the FDIC for the expected reimbursement of losses on assets covered under the various loss share agreements. These loss share agreements impose certain obligations on us that, in the event of noncompliance, could result in the delay or disallowance of some or all of our rights under those agreements. Requests for reimbursement are subject to FDIC review and may be delayed or disallowed for noncompliance. The loss share agreements are subject to interpretation by both the FDIC and FCB, and disagreements may arise regarding coverage of losses, expenses and contingencies. The purchase and assumption agreements (Agreements) for four FDIC-assisted transactions include provisions related to contingent consideration, commonly known as "clawback liability", which may be owed to the FDIC at the termination of the Agreements. The FDIC clawback liability represents an estimated payment by BancShares to the FDIC if actual cumulative losses on acquired covered assets are lower than the cumulative losses originally estimated by the FDIC at the time of acquisition. The FDIC clawback liability is estimated by discounting estimated future payments and is recorded in the Consolidated Balance Sheets as a payable to FDIC for loss share agreements. As of December 31, 2012, and 2011, the clawback liability was $101,641 and $77,866, respectively. BancShares and various subsidiaries have been named as defendants in various legal actions arising from their normal business activities in which damages in various amounts are claimed. Although the amount of any ultimate liability with respect to such matters cannot be determined, in the opinion of management, any such liability will not have a material effect on BancShares’ consolidated financial statements. During February 2011, United Western Bank, United Western’s parent company, United Western Bancorp and five of their directors filed a complaint in the United States District Court for the District of Columbia against the FDIC, the OTS and others, claiming that the seizure of United Western by the OTS and the subsequent appointment of the FDIC as receiver was illegal. The complaint requested the court to direct the OTS to remove the FDIC as receiver, return control of United Western to the plaintiffs, reimburse the plaintiffs for their costs and attorney fees and to award plaintiffs other relief as may be just and equitable. Neither BancShares nor FCB were named in the complaint. The defendants filed motions to dismiss all claims against them and, during June 2011, the Court dismissed all claims by the holding company and the individual directors, and it dismissed United Western Bank’s claim against the FDIC. However, the Court denied the motion to dismiss United Western Bank’s claim against the OTS and its Acting Director, which permits that claim to proceed. In July 2011, following passage of the Dodd-Frank Act, the OCC and the Acting Comptroller were substituted for the OTS and its Acting Director as the only defendants. On November 20, 2012, the court heard Motions for Summary Judgment filed by each side and took them under advisement. It is unclear what impact, if any, the litigation will have on FCB or the assets acquired in the United Western transaction. During March 2012, FCB received communications from the US Small Business Administration (SBA) asserting that the SBA is entitled to receive a share of amounts paid or to be paid by the FDIC to FCB relating to certain specific SBA-guaranteed loans pursuant to the loss share agreement between FCB and the FDIC applicable to Temecula Valley Bank. FCB disputes the validity of the SBA claims and is pursuing administrative relief through the SBA. FCB is unable to determine the outcome or range of loss, if any, related to these claims.
