Basis of Presentation [Text Block]	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared by West Bancorporation, Inc. (the Company) pursuant to the rules and regulations of the Securities and Exchange Commission.  Certain information and footnote disclosures normally included in financial statements have been condensed or omitted pursuant to such rules and regulations. Although management believes that the disclosures are adequate to make the information presented understandable, it is suggested that these interim consolidated financial statements be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2012.  In the opinion of management, the accompanying consolidated financial statements contain all adjustments necessary to present fairly the financial position as of September 30, 2013 and December 31, 2012, the net income and comprehensive income for the three and nine months ended September 30, 2013 and 2012, and cash flows for the nine months ended September 30, 2013 and 2012.  The results for these interim periods may not be indicative of results for the entire year or for any other period.
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP) established by the Financial Accounting Standards Board (FASB).  References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification™, sometimes referred to as the Codification or ASC.  In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses for the reporting period.  Actual results could differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term are the fair value of financial instruments and other than temporary impairment (OTTI), the valuation of other real estate owned and the allowance for loan losses.
	The accompanying unaudited consolidated financial statements include the accounts of the Company, West Bank, West Bank's wholly-owned subsidiary WB Funding Corporation (which owns an interest in a partnership) and West Bank's 99.99 percent owned subsidiary ICD IV, LLC (a community development entity).  All significant intercompany transactions and balances have been eliminated in consolidation.  In accordance with GAAP, West Bancorporation Capital Trust I is recorded on the books of the Company using the equity method of accounting and is not consolidated.
	Recent accounting developments: In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. The amendments in the update do not change the current requirements for reporting net income or other comprehensive income in the financial statements. The new amendments require an organization to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income if the item reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. Additionally, for other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP to provide additional detail about those amounts. For public companies, the amendments were effective for reporting periods beginning after December 15, 2012. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.
	In July 2013, the FASB issued Accounting Standards Update No. 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. The update requires an entity to present an unrecognized tax benefit, or portion thereof, in the statement of financial position as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward or tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position, or the the tax law of the applicable jurisdiction does not require the entity to use and the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the statement of financial position as a liability and should not be combined with deferred tax assets. For public companies, this update will be effective for interim and annual periods beginning after December 31, 2013 and early adoption is permitted. The adoption of this new guidance is not expected to have a material impact on the Company's consolidated financial statements.

Critical Accounting Policies [Abstract]
Critical Accounting Policies [Text Block]	Critical Accounting Policies
	Management has identified its most critical accounting policies to be those related to asset impairment judgments, including fair value and OTTI of available for sale investment securities, the valuation of other real estate owned and the allowance for loan losses.
	Securities available for sale are reported at fair value, with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of deferred income taxes.  The Company evaluates each of its investment securities whose value has declined below amortized cost to determine whether the decline in fair value is OTTI.  The investment portfolio is evaluated for OTTI by segregating the portfolio into two segments and applying the appropriate OTTI model. Investment securities classified as available for sale are generally evaluated for OTTI under FASB ASC 320, Investments - Debt and Equity Securities. However, certain purchased beneficial interests in securitized financial assets, including asset-backed securities and collateralized debt obligations that had credit ratings below AA at the time of purchase, are evaluated using the model outlined in FASB ASC 325, Beneficial Interests in Securitized Financial Assets.
	In determining OTTI under the FASB ASC 320 model, the review takes into consideration the severity and duration of the decline in fair value, the length of time expected for recovery, the financial condition of the issuer and other qualitative factors, as well as whether the Company intends to sell the security or whether it is more likely than not the Company will be required to sell the debt security before its anticipated recovery.
	Under the FASB ASC 325 model for the second segment of the portfolio, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.
	When OTTI occurs under either model, the amount of the OTTI recognized in earnings depends on whether the Company intends to sell the security or whether it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, the OTTI is recognized in earnings equal to the entire difference between the investment's amortized cost basis and its fair value at the balance sheet date. If the Company does not intend to sell the security and it is not more likely than not that the entity will be required to sell before recovery of its amortized cost basis, the OTTI is separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected, using the original yield as the discount rate, and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. The assessment of whether an OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at the time.
	Other real estate owned includes real estate properties acquired through or in lieu of foreclosure.  Properties are initially recorded at fair value less estimated selling costs at the date of foreclosure, thus establishing a new cost basis.  Fair value is determined by management by obtaining appraisals or other market value information at least annually.  Any write-downs in value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, valuations are periodically performed by management by obtaining updated appraisals or other market information. Any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the updated fair value less estimated selling cost. Net costs related to the holding of properties are included in noninterest expense.
	The allowance for loan losses is established through a provision for loan losses charged to expense.  Loans are charged against the allowance for loan losses when management believes that collectability of the principal is unlikely.  The Company has policies and procedures for evaluating the overall credit quality of its loan portfolio, including timely identification of potential problem loans.  On a quarterly basis, management reviews the appropriate level for the allowance for loan losses, incorporating a variety of risk considerations, both quantitative and qualitative.  Quantitative factors include the Company's historical loss experience, delinquency and charge-off trends, collateral values, known information about individual loans and other factors.  Qualitative factors include the general economic environment in the Company's market areas and the expected trend of those economic conditions.  While management uses the best information available to make its evaluations, future adjustments to the allowance may be necessary if there are significant changes in economic conditions or the other factors relied upon.  To the extent actual results differ from forecasts and management's judgment, the allowance for loan losses may be greater or less than future charge-offs.

	Securities with an amortized cost of $74,391 and $72,367 as of September 30, 2013 and December 31, 2012, respectively, were pledged as collateral on securities sold under agreements to repurchase, interest rate swaps and for other purposes as required or permitted by law or regulation.  Securities sold under agreements to repurchase are held in safekeeping at a correspondent bank on behalf of the Company.
	The amortized cost and fair value of securities available for sale as of September 30, 2013, by contractual maturity, are shown in the following table.  Certain securities have call features that allow the issuer to call the securities prior to maturity.  Expected maturities may differ from contractual maturities in collateralized mortgage obligations and mortgage-backed securities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.  Therefore, collateralized mortgage obligations and mortgage-backed securities are not included in the maturity categories within the summary.

See Note 2 for a discussion of accounting policies related to securities with unrealized losses. As of September 30, 2013, the available for sale investment portfolio included one collateralized mortgage obligation security and two trust preferred securities (TPS) with unrealized losses that have existed for longer than one year.
The Company believes the unrealized losses on investments in municipal obligations, collateralized mortgage obligations, mortgage-backed securities and corporate notes as of September 30, 2013, were due to market conditions, not reduced estimated cash flows. There was a significant increase in market interest rates in June 2013 and rates continued to rise slightly during the third quarter of 2013, particularly in the longer part of the interest rate curve. This caused a measurable decline in the fair market value of the bond portfolio. The Company does not intend to sell these securities, does not anticipate that these securities will be required to be sold before anticipated recovery, and expects full principal and interest to be collected. Therefore, the Company did not consider these investments to have OTTI at September 30, 2013.
The Company believes the unrealized loss of $859 on an investment in one single-issuer TPS issued by Heartland Financial, USA, Inc. as of September 30, 2013, was due to market conditions, not reduced estimated cash flows.  The Company does not intend to sell this security, does not anticipate that this security will be required to be sold before anticipated recovery and expects full principal and interest will be collected.  Therefore, the Company did not consider this investment to have OTTI at September 30, 2013.
As of September 30, 2013, the Company had one pooled TPS, ALESCO Preferred Funding X, Ltd., it has considered to have OTTI since 2009.  The Company engaged an independent consulting firm to assist in the valuation of this security.  In accordance with ASC 325, a discounted cash flow model was used to determine the estimated fair value of this security. Based on that valuation, management determined the security had an estimated fair value of $1,802 at September 30, 2013.  Based on the valuation work performed, no additional credit loss was recognized in the nine months ended September 30, 2013. A credit loss of $6 was recognized in the third quarter of 2012 and $179 was recognized during the first nine months of 2012. The remaining unrealized loss of $2,369 is reflected in accumulated other comprehensive income, net of taxes of $900.  The Company will continue to periodically estimate the present value of cash flows expected to be collected over the life of the security.
The following table provides a roll forward of the cumulative amount of credit-related losses recognized in earnings for the three and nine months ended September 30, 2013 and 2012.

Loans and Allowance for Loan Losses [Abstract]
Loans and Allowance for Loan Losses [Text Block]	Loans and Allowance for Loan Losses
	Loans consisted of the following segments as of September 30, 2013 and December 31, 2012.
		September 30, 2013				December 31, 2012
	Commercial	$	230,841			$	282,124
	Real estate:
	Construction, land and land development	134,048				121,911
	1-4 family residential first mortgages	46,520				49,280
	Home equity	26,683				25,536
	Commercial	513,617				441,857
	Consumer and other loans	7,917				7,099
		959,626				927,807
	Net unamortized fees and costs	(610		)		(406		)
		$	959,016			$	927,401
	Real estate loans of approximately $468,000 and $397,000 were pledged as security for Federal Home Loan Bank (FHLB) advances as of September 30, 2013 and December 31, 2012, respectively.
	Loans are stated at the principal amounts outstanding, net of unamortized loan fees and costs, with interest income recognized on the interest method based upon those outstanding loan balances.  Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the interest method. Loans are reported by the portfolio segments identified above and are analyzed by management on this basis. All loan policies identified below apply to all segments of the loan portfolio.
	Delinquencies are determined based on the payment terms of the individual loan agreements. The accrual of interest on past due and other impaired loans is generally discontinued at 90 days or when, in the opinion of management, the borrower may be unable to make all payments pursuant to contractual terms.  Unless considered collectible, all interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income, if accrued in the current year, or charged to the allowance for loan losses, if accrued in the prior year.  Generally, all payments received while a loan is on nonaccrual status are applied to the principal balance of the loan. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.
	A loan is classified as troubled debt restructured (TDR) when the Company concludes that a borrower is experiencing financial difficulties and a concession was granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden on the borrower's cash requirements, such as an extension of the payment terms beyond the original maturity date or a change in the interest rate charged.  TDR loans with extended payment terms are accounted for as impaired until performance is established. A change to the interest rate would change the classification of a loan to a TDR loan if the restructured loan yields a rate that is below a market rate for that of a new loan with comparable risk. TDR loans with below-market rates are considered impaired until fully collected. TDR loans may be reported as nonaccrual or past due 90 days, rather than as a TDR, if they are not performing per the restructured terms.
	Based upon its ongoing assessment of credit quality within the loan portfolio, the Company maintains a Watch List, which includes classified loans. These loans involve anticipated potential payment defaults or collateral inadequacies. A loan on the Watch List is considered impaired when management believes it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the terms of the loan agreement.  Impaired loans are measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent.  The amount of impairment, if any, and any subsequent changes are included in the allowance for loan losses.
	The following table sets forth the recorded investment in nonperforming loans, disaggregated by segment, held by the Company as of September 30, 2013 and December 31, 2012. The recorded investment represents principal balances net of any partial charge-offs. Related accrued interest and net unamortized fees and costs are immaterial and are excluded from the table.

	-1	Subsequent to September 30, 2013, the two loans comprising this category were brought current by the borrowers.
	-2	While TDR loans are commonly reported by the industry as nonperforming, those not classified in the nonaccrual category are accruing interest due to payment performance. TDR loans on nonaccrual status, if any, are included in the nonaccrual category. As of September 30, 2013, there were three TDR loans totaling $819 included in the nonaccrual category. As of December 31, 2012, there was one TDR loan with a balance of $810 included in the nonaccrual category.
	The following tables show the pre- and post-modification recorded investment in TDR loans by type of modification and loan segment that have occurred during the three and nine months ended September 30, 2013 and 2012.

All loans are subject to the assessment of a credit quality indicator. Risk ratings are assigned for each loan at the time of approval, and they change as circumstances dictate during the term of the loan. The Company utilizes a 9-point risk rating scale as shown below, with ratings 1 - 5 included in the Pass column, rating 6 included in the Watch column, ratings 7 - 8 included in the Substandard column and rating 9 included in the Doubtful column. All loans classified as impaired that are included in the specific evaluation of the allowance for loan losses, are included in the Substandard column along with all other loans with ratings of 7 - 8.
Risk rating 1: The loan is secured by cash equivalent collateral.
Risk rating 2: The loan is secured by properly margined marketable securities, bonds or cash surrender value of life insurance.
Risk rating 3: The borrower is in strong financial condition and has strong debt service capacity. The loan is performing as agreed, and the financial characteristics and trends of the borrower exceed industry statistics.
Risk rating 4: The borrower is in satisfactory financial condition and has satisfactory debt service capacity. The loan is performing as agreed, and the financial characteristics and trends of the borrower fall in line with industry statistics.
Risk rating 5: The borrower's financial condition is less than satisfactory. The loan is still generally paying as agreed, but strained cash flow may cause some slowness in payments. The collateral values adequately preclude loss on the loan. Financial characteristics and trends lag industry statistics. There may be noncompliance with loan covenants.
Risk rating 6: The borrower's financial condition is deficient. Payment delinquencies may be more common. Collateral values still protect from loss, but margins are narrow. The loan may be reliant on secondary sources of repayment, including liquidation of collateral and guarantor support.
Risk rating 7: The loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Well-defined weaknesses exist that jeopardize the liquidation of the debt. The Company is inadequately protected by the valuation or paying capacity of the collateral pledged. If deficiencies are not corrected, there is a distinct possibility that a loss will be sustained.
Risk rating 8: All the characteristics of rating 7 exist with the added condition that the loan is past due more than 90 days or there is reason to believe the Company will not receive its principal and interest according to the terms of the loan agreement.
Risk rating 9: All the weaknesses inherent in risk ratings 7 and 8 exist with the added condition that collection or liquidation, on the basis of currently known facts, conditions and values, is highly questionable and improbable. A loan reaching this category would most likely be charged off.
Credit quality indicators for all loans and the Company's risk rating process are dynamic and updated on a continuous basis. Risk ratings are updated as circumstances that could affect the repayment of an individual loan are brought to management's attention through an established monitoring process. Individual lenders initiate changes as appropriate for ratings 1 through 5, and changes for ratings 6 through 9 are initiated via communications with management. The likelihood of loss increases as the risk rating increases and is generally preceded by a loan appearing on the Watch List, which consists of all loans with a risk rating of 6 or worse. Written action plans with firm target dates for resolution of identified problems are maintained and reviewed on a quarterly basis for all segments of criticized loans.
In addition to the Company's internal credit monitoring practices and procedures, an outsourced independent credit review function is in place to further assess assigned internal risk classifications and monitor compliance with internal lending policies and procedures.
In all portfolio segments, the primary risks are that a borrower's income stream diminishes to the point that it is not able to make scheduled principal and interest payments and any collateral securing the loan has declined in value. The risk of declining collateral values is present for most types of loans.
Commercial loans consist primarily of loans to businesses for various purposes, including revolving lines to finance current operations, inventory and accounts receivable, and capital expenditure loans to finance equipment and other fixed assets.  These loans generally have short maturities, have either adjustable or fixed interest rates, and are either unsecured or secured by inventory, accounts receivable and/or fixed assets. For commercial loans, the primary source of repayment is from the operation of the business.
Real estate loans include various types of loans for which the Company holds real property as collateral and consist of loans on commercial properties and single and multifamily residences.  Real estate loans are typically structured to mature or reprice every 5 years with payments based on amortization periods up to 30 years.  The majority of construction loans are to contractors and developers for construction of commercial buildings or residential real estate. These loans typically have maturities up to 24 months. The Company's loan policy includes minimum appraisal and other credit guidelines.
Consumer loans include loans extended to individuals for household, family and other personal expenditures not secured by real estate.  The majority of the Company's consumer lending is for vehicles, consolidation of personal debts and household improvements. The repayment source for consumer loans, including 1-4 family residential and home equity loans, is typically wages.
The allowance for loan losses is established through a provision for loan losses charged to expense.  Loans in each of the Company's segments are charged against the allowance for loan losses when management believes that collectability of the principal is unlikely.  The allowance is an amount that management believes will be adequate to absorb probable losses on existing loans, based on an evaluation of the collectability of loans and prior loss experience.  This evaluation also takes into consideration such factors as changes in the nature and volume of the loan portfolio, overall portfolio quality, the review of specific problem loans, and current economic conditions that may affect the borrower's ability to pay.  While management uses the best information available to make its evaluation, future adjustments to the allowance may be necessary if there are significant changes in economic conditions or the other factors relied upon.
The allowance for loan losses consists of specific and general components.  The specific component relates to loans that meet the definition of impaired.  The general component covers the remaining loans and is based on historical loss experience adjusted for qualitative factors such as delinquency trends, loan growth, economic elements and local market conditions.  These same policies are applied to all segments of loans. In addition, regulatory agencies, as an integral part of their examination processes, periodically review the Company's allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.
The following tables detail changes in the allowance for loan losses by segment for the three and nine months ended September 30, 2013 and 2012.

Derivatives [Abstract]
Derivative [Text Block]	Derivatives
	The Company uses interest rate swap agreements to assist in its interest rate risk management. The notional amounts of the interest rate swaps do not represent amounts exchanged by the counterparties. The notional amount of a derivative is used to determine, along with other terms of the derivative, the amounts to be exchanged between the counterparties.
	The Company has variable rate FHLB advances, which create exposure to variability in interest payments due to changes in interest rates. In December 2012, to manage the interest rate risk related to the variability of interest payments, the Company entered into three forward-starting interest rate swap transactions, with a total notional amount of $80,000. The interest rate swaps effectively convert $80,000 of variable rate FHLB advances to fixed interest rate debt as of the forward-starting dates. The forward-starting dates on the interest rate swaps range from December 2014 to December 2015. The three swap transactions were designated as cash flow hedges of the changes in cash flows attributable to changes in LIBOR, the benchmark interest rate being hedged, associated with the interest payments made on the underlying FHLB advances with quarterly interest rate reset dates.
	In June 2013, the Company entered into a forward-starting interest rate swap transaction, with a total notional amount of $20,000, to effectively convert $20,000 of variable rate junior subordinated notes to fixed rate debt as of the forward-starting date of the swap transaction. The forward-starting date of this swap is June 30, 2014. This swap transaction was designated as a cash flow hedge of the variability in cash flows attributable to the change in LIBOR, the benchmark interest rate being hedged, associated with the interest payments made on $20,000 of the Company's junior subordinated debt, which has a quarterly interest reset date.
	At inception of each hedge transaction, the Company asserted that the underlying principal balance would remain outstanding throughout the hedge transaction, making it probable that sufficient LIBOR-based interest payments would exist through the maturity date of the swaps. The cash flow hedges were determined to be fully effective during the remaining terms of the swaps. Therefore, the aggregate fair value of the swaps is recorded in other assets or other liabilities with changes in market value recorded in other comprehensive income, net of deferred taxes. See Note 7 for additional fair value information and disclosures. The amounts included in accumulated other comprehensive income will be reclassified to interest expense should the hedge no longer be considered effective. No amount of ineffectiveness was included in net income for the nine months ended September 30, 2013, and the Company expects there will be no reclassification from accumulated other comprehensive income to interest expense for the next twelve months through September 30, 2014. The Company will continue to assess the effectiveness of the hedges on a quarterly basis.
	The Company is exposed to credit risk in the event of nonperformance by the interest rate swap counterparty. The Company minimizes this risk by entering into derivative contracts with only large, stable financial institutions, and the Company has not experienced, and does not expect, any losses from counterparty nonperformance on the interest rate swaps. The Company monitors counterparty risk in accordance with the provisions of FASB ASC 815. In addition, the interest rate swap agreements contain language outlining collateral-pledging requirements for each counterparty. Collateral must be posted when the market value exceeds certain threshold limits. As of September 30, 2013, the counterparty had pledged $2,770 of required collateral in the form of cash on deposit with a third party. The Company was not required to pledge any collateral to the counterparty as of September 30, 2013; however, the Company may need to pledge collateral in the future.
	The tables below identify the balance sheet category and fair values of the Company's derivative instruments designated as cash flow hedges as of September 30, 2013 and December 31, 2012.

	On June 27, 2013, the Company borrowed $16,000 from a commercial bank in the form of a five-year amortizing secured term loan with a variable rate of 1.95 percent plus 30-day LIBOR. The proceeds were used to finance the repurchase and cancellation of 1,440,592 shares of common stock discussed in Note 8. In the event that the Company defaults under the note, the interest rate would increase by an additional 5.0 percent. The Company also entered into a $5,000 secured line of credit that expires on June 27, 2014. Both the note and the secured line of credit are secured by a pledge of certain Company assets, including the stock of West Bank.
	During June 2013, the Company purchased a commercial lot in Coralville for construction of a new eastern Iowa main office. The purchase was financed with an eight-and-one-half-year variable payment contract for $765 with a fixed interest rate of 1.25 percent.

Fair Value Measurements [Abstract]
Fair Value Measurements [Text Block]	Fair Value Measurements
	Accounting guidance on fair value measurements and disclosures defines fair value, establishes a framework for measuring the fair value of assets and liabilities using a hierarchy system, and defines required disclosures.  It clarifies that fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts business.
	The Company's balance sheet contains securities available for sale and derivative instruments that are recorded at fair value on a recurring basis.  The three-level valuation hierarchy for disclosure of fair value is as follows:
	Level 1 uses quoted market prices in active markets for identical assets or liabilities.
	Level 2 uses observable market-based inputs or unobservable inputs that are corroborated by market data.
	Level 3 uses unobservable inputs that are not corroborated by market data.
	The Company's policy is to recognize transfers between Levels at the end of each reporting period, if applicable. There were no transfers between Levels of the fair value hierarchy during the nine months ended September 30, 2013.
	The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring basis.
	Securities available for sale: When available, quoted market prices are used to determine the fair value of investment securities. If quoted market prices are not available, the Company determines fair value based on various sources and may apply matrix pricing with observable prices for similar bonds where a price for the identical bond is not observable. The fair values of these securities are determined by pricing models that consider observable market data such as interest rate volatilities, LIBOR yield curve, credit spreads, prices from market makers and live trading systems. Level 1 securities include certain corporate bonds and preferred stocks, and would include U.S. Treasuries, if any were held. Level 2 securities include U.S. government and agency securities, collateralized mortgage obligations, mortgage-backed securities, state and political subdivision securities, and certain corporate bonds and trust preferred securities. Certain securities are not valued based on observable inputs and are, therefore, classified as Level 3. The fair value of these securities is based on management's best estimates.
	Generally, management obtains the fair value of investment securities at the end of each reporting period via a third party pricing service. Management, with the assistance of an independent investment advisory firm, reviewed the valuation process used by the third party and believes that process is valid. On a quarterly basis, management corroborates the fair values of investment securities by obtaining pricing from an independent investment advisory firm and compares the two sets of fair values. Any significant variances are reviewed and investigated. In addition, the Company has instituted a practice of further testing the fair values of a sample of securities. For that sample, the prices are further validated by management, with assistance from an independent investment advisory firm, by obtaining details of the inputs used by the pricing service. Those inputs were independently tested, and management concluded the fair values were consistent with GAAP requirements and securities were properly classified in the fair value hierarchy.
	Derivative instruments: The Company's derivative instruments consist of interest rate swaps, which are accounted for as cash flow hedges. The Company's derivative position is classified within Level 2 of the fair value hierarchy and is valued using models generally accepted in the financial services industry and that use actively quoted or observable market input values from external market data providers and/or non-binding broker-dealer quotations. The fair value of the derivative is determined using discounted cash flow models. These models’ key assumptions include the contractual terms of the respective contract along with significant observable inputs, including interest rates, yield curves, nonperformance risk and volatility. Derivative contracts are executed with a Credit Support Annex, which is a bilateral ratings-sensitive agreement that requires collateral postings at established credit threshold levels. These agreements protect the interests of the Company and its counterparties should either party suffer a credit rating deterioration.
	The following tables present the balances of assets and liabilities measured at fair value on a recurring basis by level as of September 30, 2013 and December 31, 2012.

Certain assets are measured at fair value on a nonrecurring basis. That is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).  The following tables present those assets carried on the balance sheet by caption and by level within the valuation hierarchy as of September 30, 2013 and December 31, 2012.

Loans in the previous tables consist of impaired loans for which a fair value adjustment was recorded.  Impaired loans are evaluated and valued at the lower of cost or fair value when the loan is identified as impaired.  Fair value is measured based on the value of the collateral securing these loans.  Collateral may be real estate or business assets such as equipment, inventory or accounts receivable. Fair value is determined by management evaluations or independent appraisals.  Appraised or reported values may be discounted based on management's opinions concerning market developments or the client's business.  Other real estate owned in the tables above consists of property acquired through foreclosures and settlements of loans.  Property acquired is carried at fair value of the property less estimated disposal costs. Fair value of other real estate owned is determined by management by obtaining appraisals or other market value information at the time of acquisition, is updated at least annually and may be discounted.
The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis for which the Company has utilized Level 3 inputs to determine fair value as of September 30, 2013.
		30-Sep-13

Impaired loans		$	4,535			Evaluation of collateral		Estimation of value		NM*
Other real estate owned		6,276				Appraisal		Appraisal adjustment		2.2% - 20.0% (16.3%)
* Not Meaningful. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Collateral evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate, an independent appraisal may be obtained. Types of discounts considered included aging of receivables, condition of the collateral, potential market for the collateral and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful.
GAAP requires disclosure of the fair value of financial assets and financial liabilities, including those that are not measured and reported at fair value on a recurring basis or nonrecurring basis.  The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or nonrecurring basis are discussed above.  The methodologies for other financial assets and financial liabilities are discussed below.
Cash and due from banks:  The carrying amount approximates fair value.
Federal funds sold and other short-term investments:  The carrying amount approximates fair value.
FHLB stock:  The fair value of this restricted stock is estimated at its carrying value and redemption price of $100 per share.
Loans held for sale:  The fair values of loans held for sale are based on estimated sales prices.
Loans:  The fair values of fixed-rate loans are estimated using discounted cash flow analysis based on observable market interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. The carrying value of variable-rate loans approximate their fair values.
Deposits:  The carrying amounts for demand and savings deposits, which represent the amounts payable on demand, approximate their fair values.  The fair values for fixed-rate certificates of deposit are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered on certificates with similar terms. The carrying value of variable-rate certificates of deposit approximate their fair values.
Accrued interest receivable and payable:  The fair values of both accrued interest receivable and payable approximate their carrying amounts.
Borrowings:  The carrying amounts of federal funds purchased and securities sold under agreements to repurchase approximates their fair values.  Fair values of FHLB advances, subordinated notes and other long-term borrowings are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered with similar terms.
Commitments to extend credit and standby letters of credit:  The approximate fair values of commitments and standby letters of credit are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and creditworthiness of the counterparties.
The following table includes the carrying amounts and approximate fair values of financial assets and liabilities as of September 30, 2013 and December 31, 2012.

Common Stock Repurchases [Abstract]
Common Stock Repurchases [Text Block]	Common Stock Repurchase
	On June 4, 2013, the Company entered into an agreement to repurchase 1,440,592 shares of its common stock from American Equity Investment Life Holding Company and American Equity Life Insurance Company. The shares represented 8.27 percent of the total outstanding common shares of the Company as of that date. The purchase took place on June 5, 2013 at a purchase price of $10.95 per share. The repurchased shares were canceled, thus reducing the Company's total issued and outstanding common shares to 15,969,464 as of that date. This transaction was the result of the seller indicating a desire to sell the shares. The purchase was financed as described in Note 6.

Earnings per Common Share [Abstract]
Earnings per Common Share [Text Block]	Earnings per Common Share
	Basic earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding for the period.  Diluted earnings per common share reflect the potential dilution that could occur if the Company's outstanding restricted stock units were vested. The dilutive effect was computed using the treasury stock method, which assumes all stock-based awards were exercised during the time period they were outstanding and the hypothetical proceeds from exercise were used by the Company to purchase common stock at the average market price during the period.  The incremental shares, to the extent they would have been dilutive, were included in the denominator of the diluted earnings per common share calculation.  The calculation of earnings per common share and diluted earnings per common share for the three and nine months ended September 30, 2013 and 2012 is presented in the following table.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies [Text Block]	Commitments and Contingencies
	The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit.  These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations that it uses for on-balance-sheet instruments.  The Company's commitments as of September 30, 2013 and December 31, 2012 consisted of the following approximate amounts.
		September 30, 2013		December 31, 2012
	Commitments to extend credit	$	467,388	$	360,879
	Standby letters of credit	3,518		10,488
		$	470,906	$	371,367
	West Bank has executed Mortgage Partnership Finance (MPF) Master Commitments (the Commitments) with the FHLB of Des Moines to deliver mortgage loans and to guarantee the payment of any realized losses that exceed the FHLB's first loss account for mortgages delivered under the Commitments.  West Bank receives credit enhancement fees from the FHLB for providing this guarantee and continuing to assist with managing the credit risk of the MPF Program mortgage loans.  The term of the current Commitment is through January 16, 2014.  At September 30, 2013, the liability represented by the present value of the credit enhancement fees less any expected losses in the mortgages delivered under the Commitments was approximately $457.
	On September 29, 2010, West Bank was sued in a purported class action lawsuit that, as amended, asserts that nonsufficient funds fees charged by West Bank to Iowa resident noncommercial customers on bank debit card transactions, but not checks or Automated Clearing House items, are usurious under Iowa law, rather than allowable fees, and that the sequence in which West Bank formerly posted items for payment in consumer demand accounts violated various alleged duties of good faith. As West Bank understands the current claims, plaintiffs are seeking alternative remedies that include injunctive relief, damages (including treble damages), punitive damages, refund of fees, and attorney fees. West Bank believes the lawsuit allegations are factually and legally incorrect in multiple material ways and is vigorously defending the action. The amount of potential loss, if any, cannot be reasonably estimated now because the multiple alternative claims involve different time periods and present different defenses related to potential liability, class certification, and damages.
	In the normal course of business, the Company and West Bank are involved in various other legal proceedings.  In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the consolidated financial statements.

Critical Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	The accompanying unaudited consolidated financial statements have been prepared by West Bancorporation, Inc. (the Company) pursuant to the rules and regulations of the Securities and Exchange Commission.  Certain information and footnote disclosures normally included in financial statements have been condensed or omitted pursuant to such rules and regulations. Although management believes that the disclosures are adequate to make the information presented understandable, it is suggested that these interim consolidated financial statements be read in conjunction with the Company's Annual Report on Form 10-K for the year ended December 31, 2012.  In the opinion of management, the accompanying consolidated financial statements contain all adjustments necessary to present fairly the financial position as of September 30, 2013 and December 31, 2012, the net income and comprehensive income for the three and nine months ended September 30, 2013 and 2012, and cash flows for the nine months ended September 30, 2013 and 2012.  The results for these interim periods may not be indicative of results for the entire year or for any other period.
	The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (GAAP) established by the Financial Accounting Standards Board (FASB).  References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification™, sometimes referred to as the Codification or ASC.
Use of Estimates, Policy [Policy Text Block]	In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses for the reporting period.  Actual results could differ from those estimates.  Material estimates that are particularly susceptible to significant change in the near term are the fair value of financial instruments and other than temporary impairment (OTTI), the valuation of other real estate owned and the allowance for loan losses.
Consolidation, Policy [Policy Text Block]	The accompanying unaudited consolidated financial statements include the accounts of the Company, West Bank, West Bank's wholly-owned subsidiary WB Funding Corporation (which owns an interest in a partnership) and West Bank's 99.99 percent owned subsidiary ICD IV, LLC (a community development entity).  All significant intercompany transactions and balances have been eliminated in consolidation.  In accordance with GAAP, West Bancorporation Capital Trust I is recorded on the books of the Company using the equity method of accounting and is not consolidated.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent accounting developments: In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. The amendments in the update do not change the current requirements for reporting net income or other comprehensive income in the financial statements. The new amendments require an organization to present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income if the item reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. Additionally, for other amounts that are not required under GAAP to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP to provide additional detail about those amounts. For public companies, the amendments were effective for reporting periods beginning after December 15, 2012. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.
	In July 2013, the FASB issued Accounting Standards Update No. 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. The update requires an entity to present an unrecognized tax benefit, or portion thereof, in the statement of financial position as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward, except as follows: to the extent a net operating loss carryforward or tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position, or the the tax law of the applicable jurisdiction does not require the entity to use and the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the statement of financial position as a liability and should not be combined with deferred tax assets. For public companies, this update will be effective for interim and annual periods beginning after December 31, 2013 and early adoption is permitted. The adoption of this new guidance is not expected to have a material impact on the Company's consolidated financial statements.
Marketable Securities, Available-for-sale Securities, Policy [Policy Text Block]	Securities available for sale are reported at fair value, with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of deferred income taxes.  The Company evaluates each of its investment securities whose value has declined below amortized cost to determine whether the decline in fair value is OTTI.  The investment portfolio is evaluated for OTTI by segregating the portfolio into two segments and applying the appropriate OTTI model. Investment securities classified as available for sale are generally evaluated for OTTI under FASB ASC 320, Investments - Debt and Equity Securities. However, certain purchased beneficial interests in securitized financial assets, including asset-backed securities and collateralized debt obligations that had credit ratings below AA at the time of purchase, are evaluated using the model outlined in FASB ASC 325, Beneficial Interests in Securitized Financial Assets.
	In determining OTTI under the FASB ASC 320 model, the review takes into consideration the severity and duration of the decline in fair value, the length of time expected for recovery, the financial condition of the issuer and other qualitative factors, as well as whether the Company intends to sell the security or whether it is more likely than not the Company will be required to sell the debt security before its anticipated recovery.
	Under the FASB ASC 325 model for the second segment of the portfolio, the Company compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.
	When OTTI occurs under either model, the amount of the OTTI recognized in earnings depends on whether the Company intends to sell the security or whether it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If the Company intends to sell or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, the OTTI is recognized in earnings equal to the entire difference between the investment's amortized cost basis and its fair value at the balance sheet date. If the Company does not intend to sell the security and it is not more likely than not that the entity will be required to sell before recovery of its amortized cost basis, the OTTI is separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected, using the original yield as the discount rate, and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. The assessment of whether an OTTI exists involves a high degree of subjectivity and judgment and is based on the information available to management at the time.
Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy [Policy Text Block]	Other real estate owned includes real estate properties acquired through or in lieu of foreclosure.  Properties are initially recorded at fair value less estimated selling costs at the date of foreclosure, thus establishing a new cost basis.  Fair value is determined by management by obtaining appraisals or other market value information at least annually.  Any write-downs in value at the date of acquisition are charged to the allowance for loan losses. After foreclosure, valuations are periodically performed by management by obtaining updated appraisals or other market information. Any subsequent write-downs are recorded as a charge to operations, if necessary, to reduce the carrying value of a property to the updated fair value less estimated selling cost. Net costs related to the holding of properties are included in noninterest expense.
Loans and Leases Receivable, Nonaccrual Loan and Lease Status, Policy [Policy Text Block]	Delinquencies are determined based on the payment terms of the individual loan agreements. The accrual of interest on past due and other impaired loans is generally discontinued at 90 days or when, in the opinion of management, the borrower may be unable to make all payments pursuant to contractual terms.  Unless considered collectible, all interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income, if accrued in the current year, or charged to the allowance for loan losses, if accrued in the prior year.  Generally, all payments received while a loan is on nonaccrual status are applied to the principal balance of the loan. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	A loan is classified as troubled debt restructured (TDR) when the Company concludes that a borrower is experiencing financial difficulties and a concession was granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden on the borrower's cash requirements, such as an extension of the payment terms beyond the original maturity date or a change in the interest rate charged.  TDR loans with extended payment terms are accounted for as impaired until performance is established. A change to the interest rate would change the classification of a loan to a TDR loan if the restructured loan yields a rate that is below a market rate for that of a new loan with comparable risk. TDR loans with below-market rates are considered impaired until fully collected. TDR loans may be reported as nonaccrual or past due 90 days, rather than as a TDR, if they are not performing per the restructured terms.
Impaired Financing Receivable, Policy [Policy Text Block]	Based upon its ongoing assessment of credit quality within the loan portfolio, the Company maintains a Watch List, which includes classified loans. These loans involve anticipated potential payment defaults or collateral inadequacies. A loan on the Watch List is considered impaired when management believes it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the terms of the loan agreement.  Impaired loans are measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, as a practical expedient, at the loan's observable market price or the fair value of the collateral if the loan is collateral dependent.  The amount of impairment, if any, and any subsequent changes are included in the allowance for loan losses.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	The allowance for loan losses is established through a provision for loan losses charged to expense.  Loans in each of the Company's segments are charged against the allowance for loan losses when management believes that collectability of the principal is unlikely.  The allowance is an amount that management believes will be adequate to absorb probable losses on existing loans, based on an evaluation of the collectability of loans and prior loss experience.  This evaluation also takes into consideration such factors as changes in the nature and volume of the loan portfolio, overall portfolio quality, the review of specific problem loans, and current economic conditions that may affect the borrower's ability to pay.  While management uses the best information available to make its evaluation, future adjustments to the allowance may be necessary if there are significant changes in economic conditions or the other factors relied upon.
	The allowance for loan losses consists of specific and general components.  The specific component relates to loans that meet the definition of impaired.  The general component covers the remaining loans and is based on historical loss experience adjusted for qualitative factors such as delinquency trends, loan growth, economic elements and local market conditions.  These same policies are applied to all segments of loans. In addition, regulatory agencies, as an integral part of their examination processes, periodically review the Company's allowance for loan losses, and may require the Company to make additions to the allowance based on their judgment about information available to them at the time of their examinations.
Fair Value Measurement, Policy [Policy Text Block]	Accounting guidance on fair value measurements and disclosures defines fair value, establishes a framework for measuring the fair value of assets and liabilities using a hierarchy system, and defines required disclosures.  It clarifies that fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the reporting entity transacts business.
	The Company's balance sheet contains securities available for sale and derivative instruments that are recorded at fair value on a recurring basis.  The three-level valuation hierarchy for disclosure of fair value is as follows:
	Level 1 uses quoted market prices in active markets for identical assets or liabilities.
	Level 2 uses observable market-based inputs or unobservable inputs that are corroborated by market data.
	Level 3 uses unobservable inputs that are not corroborated by market data.
	The Company's policy is to recognize transfers between Levels at the end of each reporting period, if applicable. There were no transfers between Levels of the fair value hierarchy during the nine months ended September 30, 2013.
	The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring basis.
	Securities available for sale: When available, quoted market prices are used to determine the fair value of investment securities. If quoted market prices are not available, the Company determines fair value based on various sources and may apply matrix pricing with observable prices for similar bonds where a price for the identical bond is not observable. The fair values of these securities are determined by pricing models that consider observable market data such as interest rate volatilities, LIBOR yield curve, credit spreads, prices from market makers and live trading systems. Level 1 securities include certain corporate bonds and preferred stocks, and would include U.S. Treasuries, if any were held. Level 2 securities include U.S. government and agency securities, collateralized mortgage obligations, mortgage-backed securities, state and political subdivision securities, and certain corporate bonds and trust preferred securities. Certain securities are not valued based on observable inputs and are, therefore, classified as Level 3. The fair value of these securities is based on management's best estimates.
	Generally, management obtains the fair value of investment securities at the end of each reporting period via a third party pricing service. Management, with the assistance of an independent investment advisory firm, reviewed the valuation process used by the third party and believes that process is valid. On a quarterly basis, management corroborates the fair values of investment securities by obtaining pricing from an independent investment advisory firm and compares the two sets of fair values. Any significant variances are reviewed and investigated. In addition, the Company has instituted a practice of further testing the fair values of a sample of securities. For that sample, the prices are further validated by management, with assistance from an independent investment advisory firm, by obtaining details of the inputs used by the pricing service. Those inputs were independently tested, and management concluded the fair values were consistent with GAAP requirements and securities were properly classified in the fair value hierarchy.
	Derivative instruments: The Company's derivative instruments consist of interest rate swaps, which are accounted for as cash flow hedges. The Company's derivative position is classified within Level 2 of the fair value hierarchy and is valued using models generally accepted in the financial services industry and that use actively quoted or observable market input values from external market data providers and/or non-binding broker-dealer quotations. The fair value of the derivative is determined using discounted cash flow models. These models’ key assumptions include the contractual terms of the respective contract along with significant observable inputs, including interest rates, yield curves, nonperformance risk and volatility. Derivative contracts are executed with a Credit Support Annex, which is a bilateral ratings-sensitive agreement that requires collateral postings at established credit threshold levels. These agreements protect the interests of the Company and its counterparties should either party suffer a credit rating deterioration.
Fair Value Transfer, Policy [Policy Text Block]	The Company's policy is to recognize transfers between Levels at the end of each reporting period, if applicable.
Fair Value of Financial Instruments, Policy [Policy Text Block]	GAAP requires disclosure of the fair value of financial assets and financial liabilities, including those that are not measured and reported at fair value on a recurring basis or nonrecurring basis.  The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or nonrecurring basis are discussed above.  The methodologies for other financial assets and financial liabilities are discussed below.
	Cash and due from banks:  The carrying amount approximates fair value.
	Federal funds sold and other short-term investments:  The carrying amount approximates fair value.
	FHLB stock:  The fair value of this restricted stock is estimated at its carrying value and redemption price of $100 per share.
	Loans held for sale:  The fair values of loans held for sale are based on estimated sales prices.
	Loans:  The fair values of fixed-rate loans are estimated using discounted cash flow analysis based on observable market interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. The carrying value of variable-rate loans approximate their fair values.
	Deposits:  The carrying amounts for demand and savings deposits, which represent the amounts payable on demand, approximate their fair values.  The fair values for fixed-rate certificates of deposit are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered on certificates with similar terms. The carrying value of variable-rate certificates of deposit approximate their fair values.
	Accrued interest receivable and payable:  The fair values of both accrued interest receivable and payable approximate their carrying amounts.
	Borrowings:  The carrying amounts of federal funds purchased and securities sold under agreements to repurchase approximates their fair values.  Fair values of FHLB advances, subordinated notes and other long-term borrowings are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered with similar terms.
	Commitments to extend credit and standby letters of credit:  The approximate fair values of commitments and standby letters of credit are based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and creditworthiness of the counterparties.
Earnings Per Share, Policy [Policy Text Block]	Basic earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding for the period.  Diluted earnings per common share reflect the potential dilution that could occur if the Company's outstanding restricted stock units were vested. The dilutive effect was computed using the treasury stock method, which assumes all stock-based awards were exercised during the time period they were outstanding and the hypothetical proceeds from exercise were used by the Company to purchase common stock at the average market price during the period.  The incremental shares, to the extent they would have been dilutive, were included in the denominator of the diluted earnings per common share calculation.
Comprehensive Income, Policy [Policy Text Block]	Comprehensive income consists of net income and other comprehensive income. Other comprehensive income consists of the net change in unrealized gains and losses on the Company's securities available for sale, including the noncredit-related portion of unrealized gains and losses of any OTTI securities, and the effective portion of the change in value of derivative instruments.
Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]	The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit.  These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations that it uses for on-balance-sheet instruments.

	Other real estate owned		6,276				Appraisal		Appraisal adjustment		2.2% - 20.0% (16.3%)
	* Not Meaningful. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve, but disclosure of this information would not provide meaningful insight. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Collateral evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate an independent appraisal may be obtained. Types of discounts considered included aging of receivables, condition of the collateral, potential market for the collateral and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful.
Fair Value Measurements, Nonrecurring [Table Text Block]	Certain assets are measured at fair value on a nonrecurring basis. That is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).  The following tables present those assets carried on the balance sheet by caption and by level within the valuation hierarchy as of September 30, 2013 and December 31, 2012.
