Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	'
	Note 1: Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. The results of operations reflect interim adjustments, all of which are of a normal recurring nature and which, in the opinion of Management, are necessary for a fair presentation of the results for the interim periods presented. The interim results for the three months ended March 31, 2014 and 2013 are not necessarily indicative of the results expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes as well as other information included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013.
	The Company has evaluated events and transactions subsequent to the balance sheet date. Based on this evaluation, the Company is not aware of any events or transactions that occurred subsequent to the balance sheet date but prior to filing that would require recognition or disclosure in its unaudited consolidated financial statements.

Significant Accounting Policies [Text Block]	'
	Note 2: Accounting Policies
	The Company’s accounting policies are discussed in Note 1 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.  Certain amounts in prior periods have been reclassified to conform to the current presentation.
	Certain accounting policies underlying the preparation of these financial statements require Management to make estimates and judgments. These estimates and judgments may significantly affect reported amounts of assets and liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. Management exercises judgment to estimate the appropriate level of the allowance for credit losses and the evaluation of other than temporary impairment of investment securities, which are discussed in the Company’s accounting policies.
	Recently Adopted Accounting Standards
	FASB ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, was issued July 2013 to provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar loss, or a tax credit carryforward exists.  The update provides that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, unless an exception applies.  The adoption of the update did not have a material effect on the Company’s financial statements at January 1, 2014, the date adopted.
	Recently Issued Accounting Standards
	FASB ASU 2014-01, Investments- Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects, was issued January 2014 to permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). For those investments in qualified affordable housing projects not accounted for using the proportional amortization method, the investment should be accounted for as an equity method investment or a cost method investment in accordance with GAAP.  The policy election must be applied consistently to all qualified affordable housing project investments.
	The update also requires a reporting entity to disclose information regarding its investments in qualified affordable housing projects, and the effect of the measurement of its investments in qualified affordable housing projects and the related tax credits on its financial position and results of operations.
	Management is evaluating the impact that the change in accounting policy would have on the Company’s financial statements.  Management does not expect the adoption of this update to have a material effect on the financial statements when adopted on January 1, 2015.

Expected maturities of mortgage-backed securities can differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties. In addition, such factors as prepayments and interest rates may affect the yield on the carrying value of mortgage-backed securities. At March 31, 2014 and December 31, 2013, the Company had no high-risk collateralized mortgage obligations as defined by regulatory guidelines.

The unrealized losses on the Company’s investment securities were caused by market conditions for these types of investments, particularly changes in risk-free interest rates. The Company evaluates securities on a quarterly basis including changes in security ratings issued by ratings agencies, changes in the financial condition of the issuer, and, for mortgage-related and asset-backed securities, delinquency and loss information with respect to the underlying collateral, changes in the levels of subordination for the Company’s particular position within the repayment structure and remaining credit enhancement as compared to expected credit losses of the security. Substantially all of these securities continue to be investment grade rated by a major rating agency. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset backed securities.
The Company does not intend to sell any investments and has concluded that it is more likely than not that it will not be required to sell the investments prior to recovery of the amortized cost basis. Therefore, the Company does not consider these investments to be other-than-temporarily impaired as of March 31, 2014.
The fair values of the investment securities could decline in the future if the general economy deteriorates, inflation increases, credit ratings decline, the issuer’s financial condition deteriorates, or the liquidity for securities declines. As a result, other than temporary impairments may occur in the future.
As of March 31, 2014, $876,491 thousand of investment securities were pledged to secure public deposits, short-term borrowed funds, and term repurchase agreements, compared to $778,588 thousand at December 31, 2013.

The Bank’s customers are small businesses, professionals and consumers. Given the scale of these borrowers, corporate credit rating agencies do not evaluate the borrowers’ financial condition. The Bank maintains a Loan Review Department which reports directly to the Board of Directors. The Loan Review Department performs independent evaluations of loans and assigns credit risk grades to evaluated loans using grading standards employed by bank regulatory agencies. Loans judged to carry lower-risk attributes are assigned a “pass” grade, with a minimal likelihood of loss. Loans judged to carry higher-risk attributes are referred to as “classified loans,” and are further disaggregated, with increasing expectations for loss recognition, as “substandard,” “doubtful,” and “loss.” Loan Review evaluations occur every calendar quarter.  If the Bank becomes aware of deterioration in a borrower’s performance or financial condition between Loan Review examinations, assigned risk grades are re-evaluated promptly. Credit risk grades assigned by the Loan Review Department are subject to review by the Bank’s regulatory authorities during regulatory examinations.
The following summarizes the credit risk profile by internally assigned grade:

During the three months ended March 31, 2014 and 2013, the Company modified one loan in each period with carrying values of $17 thousand and $2,009 thousand, respectively that was considered a troubled debt restructuring. The concession granted in the first quarter 2014 consisted of modification of payment terms to extend the maturity date to allow for deferred principal repayment. The concession granted in the restructuring completed in the first quarter 2013 consisted of modification of payment terms to lower the interest rate and extend the maturity date to allow for deferred principal repayment. During the three months ended March 31, 2014 and 2013, no troubled debt restructured loans defaulted. A troubled debt restructuring is considered to be in default when payments are ninety days or more past due.
The Company pledges loans to secure borrowings from the Federal Home Loan Bank (FHLB). The carrying value of the FHLB advances was $20,437 thousand and $20,577 thousand at March 31, 2014 and December 31, 2013, respectively. The loans restricted due to collateral requirements approximate $22,766 thousand and $24,242 thousand at March 31, 2014 and December 31, 2013, respectively. The amount of loans pledged exceeds collateral requirements. The FHLB does not have the right to sell or repledge such loans.
There were no loans held for sale at March 31, 2014 and December 31, 2013.

Note_9_Fair_Value_Measurements

Note 9 - Fair Value Measurements	3 Months Ended
	Mar. 31, 2014
Fair Value Disclosures [Abstract]	'
Fair Value Disclosures [Text Block]	'
	Note 9:  Fair Value Measurements
	The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.  Available for sale investment securities are recorded at fair value on a recurring basis.  Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as other real estate owned, impaired loans, certain loans held for investment, investment securities held to maturity, and other assets.  These nonrecurring fair value adjustments typically involve the lower-of-cost-or-fair value accounting of individual assets.
	In accordance with the Fair Value Measurement and Disclosure topic of the Codification, the Company bases its fair values on the price that would be received to sell an asset or paid to transfer a liability in the principal market or most advantageous market for an asset or liability in an orderly transaction between market participants on the measurement date under current market conditions.  A fair value measurement reflects all of the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance.
	The Company groups its assets and liabilities measured at fair value into a three-level hierarchy, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. When the valuation assumptions used to measure the fair value of the asset or liability are categorized within different levels of the fair value hierarchy, the asset or liability is categorized in its entirety within the lowest level of the hierarchy. These levels are:
	Level 1 – Valuation is based upon quoted prices for identical instruments traded in active exchange markets, such as the New York Stock Exchange.  Level 1 includes U.S. Treasury, equity and federal agency securities, which are traded by dealers or brokers in active markets.  Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.
	Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 2 includes mortgage-backed securities, corporate securities, asset-backed securities, municipal bonds and residential collateralized mortgage obligations.
	Level 3 – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.
	The Company relies on independent vendor pricing services to measure fair value for investment securities available for sale and investment securities held to maturity. The Company employs three pricing services. To validate the pricing of these vendors, the Company routinely randomly selects securities for pricing by two or more of the vendors; significant pricing differences, if any, are evaluated using all available independent quotes with the lowest quote generally used as the fair value estimate. In addition, the Company conducts “other than temporary impairment (OTTI)” analysis on a quarterly basis; securities selected for OTTI analysis include all securities at a market price below 95 percent of par value and with a market to book ratio below 95:100. As with any valuation technique used to estimate fair value, changes in underlying assumptions used could significantly affect the results of current and future values. Accordingly, these fair value estimates may not be realized in an actual sale of the securities.
	When the Company changes its valuation assumptions for measuring financial assets and financial liabilities at fair value, either due to changes in current market conditions or other factors, it may need to transfer those assets or liabilities to another level in the hierarchy based on the new assumptions used. The Company recognizes these transfers at the end of the reporting period that the transfers occur. For the three months ended March 31, 2014 and year ended December 31, 2013, there were no transfers in or out of levels 1, 2 or 3.
	Assets Recorded at Fair Value on a Recurring Basis
	The table below presents assets measured at fair value on a recurring basis.

	Assets Recorded at Fair Value on a Nonrecurring Basis
	The Company may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower-of-cost or fair-value accounting of individual assets. For assets measured at fair value on a nonrecurring basis that were recorded in the balance sheet at March 31, 2014 and December 31, 2013, the following table provides the level of valuation assumptions used to determine each adjustment and the carrying value of the related assets at period end.

	Level 2 – Valuation is based upon independent market prices or appraised value of the collateral, less 10% for selling costs, generally.  Level 2 includes other real estate owned that has been measured at fair value upon transfer to foreclosed assets and impaired loans collateralized by real property where a specific reserve has been established or a charge-off has been recorded. Losses on other real estate owned represent losses recognized in earnings during the period subsequent to its initial classification as foreclosed assets.
	Level 3 – Valuation is based upon estimated liquidation values of loan collateral.  The value of level 3 assets can also include a component of real estate, which is valued as described for level 2 inputs, when collateral for the impaired loan includes both business assets and real estate.  Level 3 includes impaired loans where a specific reserve has been established or a charge-off has been recorded.
	Disclosures about Fair Value of Financial Instruments
	The following section describes the valuation methodologies used by the Company for estimating fair value of financial instruments not recorded at fair value in the balance sheet.
	Cash and Due from Banks  Cash and due from banks represent U.S. dollar denominated coin and currency, deposits at the Federal Reserve Bank and correspondent banks, and amounts being settled with other banks to complete the processing of  customers’ daily transactions. Collectively, the Federal Reserve Bank and financial institutions operate in a market in which cash and due from banks transactions are processed continuously in significant daily volumes honoring the face value of the U.S. dollar.
	Investment Securities Held to Maturity  The fair values of investment securities were estimated using quoted prices as described above for Level 1 and Level 2 valuation.
	Loans  Loans were separated into two groups for valuation. Variable rate loans, except for those described below, which reprice frequently with changes in market rates were valued using historical cost. Fixed rate loans and variable rate loans that have reached their minimum contractual interest rates were valued by discounting the future cash flows expected to be received from the loans using current interest rates charged on loans with similar characteristics. Additionally, the allowance for loan losses of $32,109 thousand at March 31, 2014 and $31,693 thousand at December 31, 2013 and the fair value discount due to credit default risk associated with purchased covered and purchased non-covered loans of $643 thousand and $12,140 thousand, respectively at March 31, 2014 and purchased covered and purchased non-covered loans of $10,933 thousand and $3,245 thousand, respectively at December 31, 2013 were applied against the estimated fair values to recognize estimated future defaults of contractual cash flows. The Company does not consider these values to be a liquidation price for the loans.
	FDIC Indemnification Receivable  The fair value of the FDIC indemnification receivable recorded in Other Assets was estimated by discounting estimated future cash flows using current market rates for financial instruments with similar characteristics.
	Deposit Liabilities  Deposits with no stated maturity such as checking accounts, savings accounts and money market accounts can be readily converted to cash or used to settle transactions at face value through the broad financial system operated by the Federal Reserve Bank and financial institutions. The fair value of deposits with no stated maturity is equal to the amount payable on demand. The fair values of time deposits were estimated by discounting estimated future contractual cash flows using current market rates for financial instruments with similar characteristics.
	Short-Term Borrowed Funds  The carrying amount of securities sold under agreement to repurchase and other short-term borrowed funds approximate fair value due to the relatively short period of time between their origination and their expected realization.
	Federal Home Loan Bank Advances  The fair values of FHLB advances were estimated by using redemption amounts quoted by the Federal Home Loan Bank of San Francisco.
	Term Repurchase Agreement  The fair value of the term repurchase agreement was estimated by using interpolated yields for financial instruments with similar characteristics.
	The table below is a summary of fair value estimates for financial instruments and the level of the fair value hierarchy within which the fair value measurements are categorized, excluding financial instruments recorded at fair value on a recurring basis. The values assigned do not necessarily represent amounts which ultimately may be realized for assets or paid to settle liabilities. In addition, these values do not give effect to adjustments to fair value which may occur when financial instruments are sold or settled in larger quantities.  The carrying amounts in the following table are recorded in the balance sheet under the indicated captions.
	The Company has not included assets and liabilities that are not financial instruments, such as goodwill, long-term relationships with deposit, merchant processing and trust customers, other purchased intangibles, premises and equipment, deferred taxes and other assets and liabilities. The total estimated fair values do not represent, and should not be construed to represent, the underlying value of the Company.

	Note 10: Commitments and Contingent Liabilities
	Loan commitments are agreements to lend to a customer provided there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future funding requirements. Loan commitments are subject to the Company’s normal credit policies and collateral requirements. Unfunded loan commitments were $310,127 thousand and $320,934 thousand at March 31, 2014 and December 31, 2013, respectively. Standby letters of credit commit the Company to make payments on behalf of customers when certain specified future events occur. Standby letters of credit are primarily issued to support customers’ short-term financing requirements and must meet the Company’s normal credit policies and collateral requirements. Financial and performance standby letters of credit outstanding totaled $31,213 thousand and $31,777 thousand at March 31, 2014 and December 31, 2013, respectively. The Company also had commitments for commercial and similar letters of credit of $344 thousand at March 31, 2014 and December 31, 2013.
	Due to the nature of its business, the Company is subject to various threatened or filed legal cases. Based on the advice of legal counsel, the Company does not expect such cases will have a material, adverse effect on its financial position or results of operations. Legal liabilities are accrued when obligations become probable and the amount is reasonably estimable.

	Note 11: Earnings Per Common Share
	The table below shows earnings per common share and diluted earnings per common share. Basic earnings per common share are computed by dividing net income by the average number of common shares outstanding during the period. Diluted earnings per common share are computed by dividing net income by the average number of common shares outstanding during the period plus the impact of common stock equivalents.

	For the three months ended March 31, 2014 and 2013, options to purchase 1,148 thousand and 2,317 thousand shares of common stock, respectively, were outstanding but not included in the computation of diluted net income per share because the option exercise price exceeded the fair value of the stock such that their inclusion would have had an anti-dilutive effect.

	FASB ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists, was issued July 2013 to provide guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar loss, or a tax credit carryforward exists.  The update provides that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, unless an exception applies.  The adoption of the update did not have a material effect on the Company’s financial statements at January 1, 2014, the date adopted.
	Recently Issued Accounting Standards
	FASB ASU 2014-01, Investments- Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects, was issued January 2014 to permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense (benefit). For those investments in qualified affordable housing projects not accounted for using the proportional amortization method, the investment should be accounted for as an equity method investment or a cost method investment in accordance with GAAP.  The policy election must be applied consistently to all qualified affordable housing project investments.
	The update also requires a reporting entity to disclose information regarding its investments in qualified affordable housing projects, and the effect of the measurement of its investments in qualified affordable housing projects and the related tax credits on its financial position and results of operations.
	Management is evaluating the impact that the change in accounting policy would have on the Company’s financial statements.  Management does not expect the adoption of this update to have a material effect on the financial statements when adopted on January 1, 2015
