	2. Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2013. For further information, refer to the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.
	The preparation of the condensed consolidated financial statements in accordance with GAAP requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. The most significant estimates subject to change are the allowance for loan losses, goodwill impairment, and other-than-temporary impairment.

	3. Recent Accounting Pronouncements
	In January 2013, the Financial Accounting Standard Board (“FASB”) issued ASU 2013-01, “Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities.” ASU No. 2013-01 clarifies that the scope of Update 2011-11 applies to derivatives, repurchase agreements, and securities lending transactions to the extent that they are either offset in the financial statements or subject to an enforceable master netting arrangement or similar agreement. ASU 2013-01 became effective for interim and annual periods beginning on or after January 1, 2013. Adoption of ASU 2013-01 did not have a significant impact on the Company’s consolidated financial statements. See Note 15 to the Company’s consolidated financial statements for the disclosure of adoption of ASU 2013-01.
	In February 2013, the FASB issued ASU 2013-02 “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” ASU 2013-02 amends Topic 220, “Comprehensive Income,” to improve the reporting of reclassification out of accumulated other comprehensive income. The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified and to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. ASU 2013-02 became effective prospectively for reporting periods beginning after December 15, 2012. Adoption of ASU 2013-02 did not have a significant impact on the Company’s consolidated financial statements. See Note 16 to the Company’s condensed consolidated financial statements for the disclosure of adoption of ASU 2013-02.

Earnings Per Share [Abstract]	'
Earnings Per Share [Text Block]	'
	4. Earnings per Share
	Basic earnings per share exclude dilution and is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock and resulted in the issuance of common stock that then shared in earnings. Potential dilution is excluded from computation of diluted per-share amounts when a net loss from operations exists.
	Outstanding stock options with anti-dilutive effect were not included in the computation of diluted earnings per share. The following table sets forth earnings per common share calculations:

	5. Stock-Based Compensation
	Under the Company’s equity incentive plans, directors and eligible employees may be granted incentive or non-statutory stock options and/or restricted stock units, or awarded non-vested stock. As of September 30, 2013, the only options granted by the Company were non-statutory stock options to selected Bank officers and non-employee directors at exercise prices equal to the fair market value of a share of the Company’s common stock on the date of grant. Such options have a maximum ten-year term and vest in 20% annual increments (subject to early termination in certain events) except certain options granted to the Chief Executive Officer of the Company in 2005 and 2008. If such options expire or terminate without having been exercised, any shares not purchased will again be available for future grants or awards. There were no options granted during the first nine months of 2013 or during 2012.
	Option compensation expense was zero for the three months ended September 30, 2013, and $194,000 for the three months ended September 30, 2012. For the nine months ended September 30, option compensation expense totaled $129,000 for 2013 and $581,000 for 2012. Stock-based compensation is recognized ratably over the requisite service period for all awards. All unrecognized stock-based compensation expense was fully recognized as of September 30, 2013.
	No stock options were exercised in the first nine months of 2013 compared to 39,784 shares issued on the exercise of stock options in the first nine months 2012. Cash received totaled $647,000 and the aggregate intrinsic value totaled $34,000 from the exercise of stock options during the nine months ended September 30, 2012.

	6. Investment Securities
	Investment securities were $1.7 billion at September 30, 2013, compared to $2.1 billion at December 31, 2012. During the first quarter of 2013, due to the ongoing discussions regarding corporate income tax rates which could have a negative impact on the after-tax yields and fair values of the Company’s portfolio of municipal securities, the Company determined it may sell such securities in response to market conditions. As a result, the Company reclassified its municipal securities from securities held-to-maturity to securities available-for-sale. Concurrent with this reclassification, the Company also reclassified all other securities held-to-maturity, which together with the municipal securities had an amortized cost on the date of transfer of $722.5 million, to securities available-for-sale. At the reclassification date, a net unrealized gain was recorded in other comprehensive income for these securities totaling $40.5 million.
	The following table reflects the amortized cost, gross unrealized gains, gross unrealized losses, and fair values of investment securities as of September 30, 2013, and December 31, 2012:

	Proceeds from sales of mortgage-backed securities were $348.7 million and repayments, maturities and calls of mortgage-backed securities were $237.9 million during the first nine months of 2013 compared to proceeds from sales of $369.0 million and repayments, maturities, and calls of $280.7 million during the same period a year ago. Proceeds from sales of other investment securities were $555.2 million during the first nine months of 2013 compared to $61.0 million during the same period year ago. Proceeds from maturity and calls of other investment securities were $180.1 million during the first nine months of 2013 compared to $494.2 million during the same period a year ago. Gains of $27.2 million and no losses were realized on sales and calls of investment securities during the first nine months of 2013 compared to gains of $13.8 million and losses of $607,000 realized for the same period a year ago.
	The unrealized loss on investments in corporate bonds relates to the Company’s investment in 14 issues of bonds of financial institutions, all of which were investment grade at the date of acquisition and as of September 30, 2013. The unrealized losses for these now floating rate securities were primarily caused by the widening of credit spreads since the dates of acquisition. The contractual terms of those investments do not permit the issuers to settle the security at a price less than the amortized cost of the investment. The Company currently does not believe it is probable that it will be unable to collect all amounts due according to the contractual terms of the investments. Therefore, it is expected that these bonds would not be settled at a price less than the amortized cost of the investment. Because the Company does not intend to sell and would not be required to sell these investments until a recovery of fair value, which may be at maturity, it does not consider its investments in these corporate bonds to be other-than-temporarily impaired at September 30, 2013.
	The temporarily impaired securities represent 58.6% of the fair value of investment securities as of September 30, 2013. Unrealized losses for securities with unrealized losses for less than twelve months represent 4.9%, and securities with unrealized losses for twelve months or more represent 5.6%, of the historical cost of these securities. Unrealized losses on these securities generally resulted from increases in interest rates or spreads subsequent to the date that these securities were purchased.
	At September 30, 2013, management believed the impairment was temporary and, accordingly, no impairment loss has been recognized in our condensed consolidated statements of operations. The Company expects to recover the amortized cost basis of its debt securities, and has no intent to sell and will not be required to sell available-for-sale debt securities that have declined below their cost before their anticipated recovery.
	The table below shows the fair value and unrealized losses of the temporarily impaired securities in our investment securities portfolio as of September 30, 2013, and December 31, 2012:

The determination of the amount of the allowance for credit losses for impaired loans is based on management’s current judgment about the credit quality of the loan portfolio and takes into consideration known relevant internal and external factors that affect collectibility when determining the appropriate level for the allowance for credit losses. The nature of the process by which the Bank determines the appropriate allowance for credit losses requires the exercise of considerable judgment. This allowance evaluation process is also applied to troubled debt restructurings since they are considered to be impaired loans.
A troubled debt restructuring is a formal modification of the terms of a loan when the lender, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower. The concessions may be granted in various forms, including a change in the stated interest rate, a reduction in the loan balance or accrued interest, or an extension of the maturity date that causes significant delay in payment.
TDRs on accrual status are comprised of the loans that have, pursuant to the Bank’s policy, performed under the restructured terms and have demonstrated sustained performance under the modified terms for nine months before being returned to accrual status. The sustained performance considered by management pursuant to its policy includes the periods prior to the modification if the prior performance met or exceeded the modified terms. This would include cash paid by the borrower prior to the restructure to set up interest reserves.
At September 30, 2013, accruing TDRs were $115.9 million and non-accrual TDRs were $43.6 million compared to accruing TDRs of $144.7 million and non-accrual TDRs of $47.7 million at December 31, 2012. The Company allocated specific reserves of $6.3 million to accruing TDRs and $4.5 million to non-accrual TDRs at September 30, 2013, and $1.1 million to accruing TDRs and $7.8 million to non-accrual TDRs at December 31, 2012. The following table presents TDRs that were modified during the first nine months of 2013 and 2012, their specific reserve at September 30, 2013, and charge-offs during the first nine months of 2013 and 2012:

Modifications of the loan terms during the first nine months of 2013 were in the form of changes in the stated interest rate, and in payment terms to interest only from principal and interest or reduction in monthly payment amount, multiple note structure, and waiver of late charges and collection fees.  The length of time for which modifications involving a reduction of the stated interest rate or changes in payment terms that were documented ranged from twelve months to three years from the modification date.
We expect that the TDR loans on accruing status as of September 30, 2013, which were all performing in accordance with their restructured terms, will continue to comply with the restructured terms because of the reduced principal or interest payments on these loans. A summary of TDRs by type of concession, and by type of loan as of September 30, 2013, and December 31, 2012, is shown below:

A loan is considered to be in payment default once it is 60 to 90 days contractually past due under the modified terms.  Two commercial loans of $1.4 million were modified as TDRs during the previous twelve months and subsequently defaulted as of September 30, 2013, within the three months and nine months ended September 30, 2013.  None of these TDRs incurred any charge-offs within the twelve month period.
Under the Company’s internal underwriting policy, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification in order to determine whether a borrower is experiencing financial difficulty.
As of September 30, 2013, there were no commitments to lend additional funds to those borrowers whose loans have been restructured, were considered impaired, or were on non-accrual status.
As part of the on-going monitoring of the credit quality of our loan portfolio, the Company utilizes a risk grading matrix to assign a risk grade to each loan. The risk rating categories can be generally described by the following grouping for non-homogeneous loans:
	●	Pass/Watch – These loans range from minimal credit risk to lower than average, but still acceptable, credit risk.
	●	Special Mention – Borrower is fundamentally sound and loan is currently protected but adverse trends are apparent that, if not corrected, may affect ability to repay. Primary source of loan repayment remains viable but there is increasing reliance on collateral or guarantor support.
	●	Substandard – These loans are inadequately protected by current sound net worth, paying capacity, or pledged collateral. Well-defined weaknesses exist that could jeopardize repayment of debt. Loss may not be imminent, but if weaknesses are not corrected, there is a good possibility of some loss.
	●	Doubtful – The possibility of loss is extremely high, but due to identifiable and important pending events (which may strengthen the loan), a loss classification is deferred until the situation is better defined.
	●	Loss – These loans are considered uncollectible and of such little value that to continue to carry the loan as an active asset is no longer warranted.

	8. Commitments and Contingencies
	The Company is involved in various litigation concerning transactions entered into during the normal course of business. Management, after consultation with legal counsel, does not believe that the resolution of such litigation will have a material effect upon its consolidated financial condition, results of operations, or liquidity taken as a whole. Although the Company establishes accruals for legal proceedings when information related to the loss contingencies represented by those matters indicates both that a loss is probable and that the amount of loss can be reasonably estimated, the Company does not have accruals for all legal proceedings where there is a risk of loss. In addition, amounts accrued may not represent the ultimate loss to the Company from the legal proceedings in question. Thus, ultimate losses may be higher or lower, and possibly significantly so, than the amounts accrued for legal loss contingencies.
	In the normal course of business, the Company becomes a party to financial instruments with off-balance sheet risk to meet the financing needs of its customers. These financial instruments include commitments to extend credit in the form of loans, or through commercial or standby letters of credit, and financial guarantees. These instruments represent varying degrees of exposure to risk in excess of the amounts included in the accompanying condensed consolidated balance sheets. The contractual or notional amount of these instruments indicates a level of activity associated with a particular class of financial instrument and is not a reflection of the level of expected losses, if any.

	9. Securities Sold Under Agreements to Repurchase
	Securities sold under agreements to repurchase were $800 million with a weighted average rate of 3.87% at September 30, 2013, compared to $1.3 billion with a weighted average rate of 3.84% at December 31, 2012. In 2012, the Company modified $200.0 million of securities sold under agreements to repurchase by extending the term by an additional four years on average, reducing the rate by an average of 168 basis points, and removing the callable feature. In 2012, the Company prepaid securities sold under agreements to repurchase totaling $150 million with a weighted average rate of 4.43% and incurred prepayment penalties of $9.4 million. In the first nine months of 2013, the Company prepaid securities sold under agreements to repurchase totaling $450 million with a weighted average rate of 3.79% and incurred prepayment penalties of $22.6 million. Five floating-to-fixed rate agreements totaling $300.0 million have initial floating rates for a period of time ranging from six months to one year, with floating rates ranging from the three-month LIBOR minus 200 basis points to the three-month LIBOR rate minus 340 basis points. Thereafter, the rates are fixed for the remainder of the term, with interest rates ranging from 4.78% to 5.07%. After the initial floating rate term, the counter parties have the right to terminate the transaction at par at the fixed rate reset date and quarterly thereafter. Six fixed-to-floating rate agreements totaling $300.0 million have initial fixed rates ranging from 1.00% to 3.50% with initial fixed rate terms ranging from six months to 18 months. For the remaining term, the rates float at 8% minus the three-month LIBOR rate with a maximum rate ranging from 3.50% to 3.75% and minimum rate of 0.0%. After the initial fixed rate term, the counter parties have the right to terminate the transaction at par at the floating rate reset date and quarterly thereafter. The table below provides summary data for the $600 million of callable securities sold under agreements to repurchase as of September 30, 2013:

	These transactions are accounted for as collateralized financing transactions and recorded at the amounts at which the securities were sold. The Company may have to provide additional collateral for the repurchase agreements, as necessary. The underlying collateral pledged for the repurchase agreements consists of U.S. Treasury securities, U.S. government agency securities, and mortgage-backed securities with a fair value of $920.1 million as of September 30, 2013, and $1.4 billion as of December 31, 2012.

	Income tax expense totaled $52.5 million, or an effective tax rate of 36.5%, for the first nine months of 2013, compared to an income tax expense of $50.9 million, or an effective tax rate of 36.3%, for the same period a year ago. The effective tax rate includes the impact of the utilization of low income housing tax credits and recognition of other tax credits for both years.
	As of December 31, 2012, the Company had income tax refunds receivable of $12.4 million. These income tax receivables are included in other assets in the accompanying condensed consolidated balance sheets.
	The Company’s tax returns are open for audits by the Internal Revenue Service back to 2010 and by the California Franchise Tax Board back to 2003. The Company is under audit by the California Franchise Tax Board for the years 2003 to 2007. As the Company is presently under audit by a number of tax authorities, it is reasonably possible that unrecognized tax benefits could change significantly over the next twelve months. The Company does not expect that any such changes would have a material impact on its annual effective tax rate.

Fair Value, Measurement Inputs, Disclosure [Text Block]	'
	11. Fair Value Measurements
	The Company adopted ASC Topic 820 on January 1, 2008, and determined the fair values of our financial instruments based on the following:
		●	Level 1 - Quoted prices in active markets for identical assets or liabilities.
		●	Level 2 - Observable prices in active markets for similar assets or liabilities; prices for identical or similar assets or liabilities in markets that are not active; directly observable market inputs for substantially the full term of the asset and liability; market inputs that are not directly observable but are derived from or corroborated by observable market data.
		●	Level 3 – Unobservable inputs based on the Company’s own judgment about the assumptions that a market participant would use.
	The Company uses the following methodologies to measure the fair value of its financial assets and liabilities on a recurring basis:
	Securities Available for Sale. For certain actively traded agency preferred stocks, mutual funds, and U.S. Treasury securities, the Company measures the fair value based on quoted market prices in active exchange markets at the reporting date, a Level 1 measurement. The Company also measures securities by using quoted market prices for similar securities or dealer quotes, a Level 2 measurement. This category generally includes U.S. Government agency securities, state and municipal securities, mortgage-backed securities (“MBS”), commercial MBS, collateralized mortgage obligations, asset-backed securities, corporate bonds and trust preferred securities.
	Trading Securities. The Company measures the fair value of trading securities based on quoted market prices in active exchange markets at the reporting date, a Level 1 measurement. The Company also measures the fair value for other trading securities based on quoted market prices for similar securities or dealer quotes, a Level 2 measurement.
	Warrants. The Company measures the fair value of warrants based on unobservable inputs based on assumption and management judgment, a Level 3 measurement.
	Currency Option and Foreign Exchange Contracts. The Company measures the fair value of currency option and foreign exchange contracts based on dealer quotes on a recurring basis, a Level 2 measurement.
	Interest Rate Swaps. Fair value of interest rate swaps is derived from observable market prices for similar assets on a recurring basis, a Level 2 measurement.
	The valuation techniques for the assets and liabilities valued on a nonrecurring basis are as follows:
	Impaired Loans. The Company does not record loans at fair value on a recurring basis. However, from time to time, nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on either the current appraised value of the collateral, a Level 2 measurement, or management’s judgment and estimation of value reported on older appraisals that are then adjusted based on recent market trends, a Level 3 measurement.
	Goodwill. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. The two-step impairment testing process, if needed, begins by assigning net assets and goodwill to the three reporting units— Commercial Lending, Retail Banking, and East Coast Operations.  The Company then completes “step one” of the impairment test by comparing the fair value of each reporting unit (as determined based on the discussion below) with the recorded book value (or “carrying amount”) of its net assets, with goodwill included in the computation of the carrying amount.  If the fair value of a reporting unit exceeds its carrying amount, goodwill of that reporting unit is not considered impaired, and “step two” of the impairment test is not necessary.  If the carrying amount of a reporting unit exceeds its fair value, step two of the impairment test is performed to determine the amount of impairment.  Step two of the impairment test compares the carrying amount of the reporting unit’s goodwill to the “implied fair value” of that goodwill.  The implied fair value of goodwill is computed by assuming that all assets and liabilities of the reporting unit would be adjusted to the current fair value, with the offset as an adjustment to goodwill.  This adjusted goodwill balance is the implied fair value used in step two.  An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its implied fair value. In connection with the determination of fair value, certain data and information is utilized, including earnings forecasts at the reporting unit level for the next four years.  Other key assumptions include terminal values based on future growth rates and discount rates for valuing the cash flows, which have inputs for the risk-free rate, market risk premium, and adjustments to reflect inherent risk and required market returns. Because of the significance of unobservable inputs in the valuation of goodwill impairment, goodwill subject to nonrecurring fair value adjustments is classified as a Level 3 measurement.
	Core Deposit Intangibles. Core deposit intangibles is initially recorded at fair value based on a valuation of the core deposits acquired and is amortized over its estimated useful life to its residual value in proportion to the economic benefits consumed. The Company assesses the recoverability of this intangible asset on a nonrecurring basis using the core deposits remaining at the assessment date and the fair value of cash flows expected to be generated from the core deposits, a Level 3 measurement.
	Other Real Estate Owned. Real estate acquired in the settlement of loans is initially recorded at fair value based on the appraised value of the property on the date of transfer, less estimated costs to sell, a Level 2 measurement. From time to time, nonrecurring fair value adjustments are made to other real estate owned based on the current updated appraised value of the property, also a Level 2 measurement, or management’s judgment and estimation of value reported on older appraisals that are then adjusted based on recent market trends, a Level 3 measurement.
	Investments in Venture Capital. The Company periodically reviews its investments in venture capital for other-than-temporary impairment on a nonrecurring basis. Investments in venture capital were written down to their fair value based on available financial reports from venture capital partnerships and management’s judgment and estimation, a Level 3 measurement.
	Equity Investments. The Company records equity investments at fair value on a nonrecurring basis based on quoted market prices in active exchange markets at the reporting date, a Level 1 measurement.
	The following table presents the Company’s hierarchy for its assets and liabilities measured at fair value on a recurring basis as of September 30, 2013, and December 31, 2012:

The significant unobservable (Level 3) inputs used in the fair value measurement of collateral for collateral-dependent impaired loans was primarily based on the appraised value of collateral adjusted by estimated sales cost and commissions. The Company generally obtains new appraisal reports every nine months. As the Company’s primary objective in the event of default would be to monetize the collateral to settle the outstanding balance of the loan, less marketable collateral would receive a larger discount. During the reported periods, collateral discounts ranged from 45% in the case of accounts receivable collateral to 65% in the case of inventory collateral.
The significant unobservable inputs used in the fair value measurement of loans held for sale was primarily based on the quoted price or sale price adjusted by estimated sales cost and commissions. The significant unobservable inputs used in the fair value measurement of other real estate owned (“OREO”) was primarily based on the appraised value of OREO adjusted by estimated sales cost and commissions.
The Company applies estimated sales cost and commission ranging from 3% to 6% to collateral value of impaired loans, quoted price, or loan sale price of loans held for sale, and appraised value of OREOs.
The significant unobservable inputs in the Black-Scholes option pricing model for the fair value of warrants are the expected life of warrant ranging from 2 to 4 years, risk-free interest rate from 0.33% to 1.01%, and stock volatility from 12.6% to 16.6%.

Fair Value Disclosures [Text Block]	'
	12. Fair Value of Financial Instruments
	The following methods and assumptions were used to estimate the fair value of each class of financial instruments.
	Cash and Cash Equivalents. For cash and cash equivalents, the carrying amount was assumed to be a reasonable estimate of fair value, a Level 1 measurement.
	Short-term Investments. For short-term investments, the carrying amount was assumed to be a reasonable estimate of fair value, a Level 1 measurement.
	Securities Purchased under Agreements to Resell. The fair value of securities purchased under agreements to resell is based on dealer quotes, a Level 2 measurement.
	Securities. For securities, including securities held-to-maturity, available-for-sale and for trading, fair values were based on quoted market prices at the reporting date. If a quoted market price was not available, fair value was estimated using quoted market prices for similar securities or dealer quotes. For certain actively traded agency preferred stocks and U.S. Treasury securities, the Company measures the fair value based on quoted market prices in active exchange markets at the reporting date, a Level 1 measurement. The Company also measures securities by using quoted market prices for similar securities or dealer quotes, a Level 2 measurement. This category generally includes U.S. Government agency securities, state and municipal securities, mortgage-backed securities (“MBS”), commercial MBS, collateralized mortgage obligations, asset-backed securities, and corporate bonds.
	Loans. Fair values were estimated for portfolios of loans with similar financial characteristics. Each loan category was further segmented into fixed and adjustable rate interest terms and by performing and non-performing categories.
	The fair value of performing loans was calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan, a Level 3 measurement.
	The fair value of impaired loans was calculated based on the net realizable fair value of the collateral or the observable market price of the most recent sale or quoted price from loans held for sale. The Company does not record loans at fair value on a recurring basis. Nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on the current appraised value of the collateral, a Level 2 measurement.
	Deposit Liabilities. The fair value of demand deposits, savings accounts, and certain money market deposits was assumed to be the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit was estimated using the rates currently offered for deposits with similar remaining maturities, a Level 3 measurement.
	Securities Sold under Agreements to Repurchase. The fair value of securities sold under agreements to repurchase is based on dealer quotes, a Level 2 measurement.
	Advances from Federal Home Loan Bank (“FHLB”). The fair value of the advances is based on quotes from the FHLB to settle the advances, a Level 2 measurement.
	Other Borrowings. This category includes borrowings from other financial institutions.  The fair value of other borrowings is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk, a Level 3 measurement.
	Long-term Debt. The fair value of long-term debt is estimated based on the quoted market prices or dealer quotes, a Level 2 measurement.
	Currency Option and Foreign Exchange Contracts. The Company measures the fair value of currency option and foreign exchange contracts based on dealer quotes, a Level 2 measurement.
	Interest Rate Swaps. Fair value of interest rate swaps was derived from observable market prices for similar assets, a Level 2 measurement.
	Off-Balance-Sheet Financial Instruments. The fair value of commitments to extend credit, standby letters of credit, and financial guarantees written were estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counter parties. The fair value of guarantees and letters of credit was based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counter parties at the reporting date. The fair value of off-balance-sheet financial instruments was based on the assumptions that a market participant would use, a Level 3 measurement.
	Fair value was estimated in accordance with ASC Topic 825, formerly SFAS 107. Fair value estimates were made at specific points in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Bank’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Bank’s financial instruments, fair value estimates were based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates were subjective in nature and involved uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. The following table presents the estimated fair value of financial instruments as of September 30, 2013, and as of December 31, 2012:

	13. Goodwill and Goodwill Impairment
	The Company’s policy is to assess goodwill for impairment at the reporting unit level on an annual basis or between annual assessments if a triggering event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.  Impairment is the condition that exists when the carrying amount of goodwill exceeds its implied fair value.
	The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC Topic 350. The two-step impairment testing process, if needed, begins by assigning net assets and goodwill to our three reporting units— Commercial Lending, Retail Banking, and East Coast Operations.  The Company then completes “step one” of the impairment test by comparing the fair value of each reporting unit (as determined based on the discussion below) with the recorded book value (or “carrying amount”) of its net assets, with goodwill included in the computation of the carrying amount.  If the fair value of a reporting unit exceeds its carrying amount, goodwill of that reporting unit is not considered impaired, and “step two” of the impairment test is not necessary.  If the carrying amount of a reporting unit exceeds its fair value, step two of the impairment test is performed to determine the amount of impairment.  Step two of the impairment test compares the carrying amount of the reporting unit’s goodwill to the “implied fair value” of that goodwill.  The implied fair value of goodwill is computed by assuming that all assets and liabilities of the reporting unit would be adjusted to the current fair value, with the offset as an adjustment to goodwill.  This adjusted goodwill balance is the implied fair value used in step two.  An impairment charge is recognized for the amount by which the carrying amount of goodwill exceeds its implied fair value.
	At September 30, 2013, the Company’s market capitalization was above book value and there was no triggering event that required the Company to assess goodwill for impairment as of an interim date.

Derivative Instrument Detail [Abstract]	'
Schedule of Derivative Instruments [Table Text Block]	'
	14. Financial Derivatives
	It is the policy of the Company not to speculate on the future direction of interest rates. However, the Company enters into financial derivatives in order to seek mitigation of exposure to interest rate risks related to our interest-earning assets and interest-bearing liabilities. We believe that these transactions, when properly structured and managed, may provide a hedge against inherent interest rate risk in the Company’s assets or liabilities and against risk in specific transactions. In such instances, the Company may protect its position through the purchase or sale of interest rate futures contracts for a specific cash or interest rate risk position. Other hedge transactions may be implemented using interest rate swaps, interest rate caps, floors, financial futures, forward rate agreements, and options on futures or bonds. Prior to considering any hedging activities, we seek to analyze the costs and benefits of the hedge in comparison to other viable alternative strategies. All hedges will require an assessment of basis risk and must be approved by the Bank’s Investment Committee.
	The Company follows ASC Topic 815 that establishes accounting and reporting standards for financial derivatives, including certain financial derivatives embedded in other contracts, and hedging activities. It requires the recognition of all financial derivatives as assets or liabilities in the Company’s consolidated balance sheet and measurement of those financial derivatives at fair value. The accounting treatment of changes in fair value is dependent upon whether or not a financial derivative is designated as a hedge and, if so, the type of hedge.
	The Company enters into foreign exchange forward contracts and foreign currency option contracts with various counter parties to mitigate the risk of fluctuations in foreign currency exchange rates for foreign exchange certificates of deposit, foreign exchange contracts, or foreign currency option contracts entered into with our clients. These contracts are not designated as hedging instruments and are recorded at fair value in our condensed consolidated balance sheets. Changes in the fair value of these contracts as well as the related foreign exchange certificates of deposit, foreign exchange contracts or foreign currency option contracts are recognized immediately in net income as a component of non-interest income. Period end gross positive fair values are recorded in other assets and gross negative fair values are recorded in other liabilities. At September 30, 2013, the notional amount of option contracts totaled $101,000 with a net negative fair value of $1,000. Spot and forward contracts in the total notional amount of $277.4 million had a positive fair value of $5.8 million at September 30, 2013. Spot and forward contracts in the total notional amount of $185.6 million had a negative fair value of $4.7 million at September 30, 2013. At December 31, 2012, the notional amount of option contracts totaled $209,000 with a net negative fair value of $2,000. Spot and forward contracts in the total notional amount of $188.1 million had a positive fair value of $2.9 million at December 31, 2012. Spot and forward contracts in the total notional amount of $133.7 million had a negative fair value of $1.6 million at December 31, 2012.

	15. Balance Sheet Offsetting
	Certain financial instruments, including resell and repurchase agreements, securities lending arrangements and derivatives, may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements or similar agreements. The Company’s securities sold with agreement to repurchase and derivative transactions with upstream financial institution counter parties are generally executed under International Swaps and Derivative Association master agreements which include “right of set-off” provisions. In such cases there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, the Company does not generally offset such financial instruments for financial reporting purposes.

	16. Stockholders’ Equity
	Total equity was $1.44 billion at September 30, 2013, a decrease of $194.2 million, or 11.9%, from $1.63 billion at December 31, 2012, primarily due to the redemptions in two equal installments on March 20, 2013 and on September 30, 2013 of Bancorp’s $258 million of Series B Preferred Stock issued under the U.S. Treasury's TARP Capital Purchase Program and increases in unrealized losses on securities available for sale of $21.6 million offset by $91.7 million in net income.
	The accumulated other comprehensive loss as of September 30, 2013, was all from unrealized losses on securities available-for-sale. Activity in accumulated other comprehensive income, net of tax, and reclassification out of accumulated other comprehensive income for the three months and nine months ended September 30, 2013, was as follows:
