Notes to Consolidated Financial Statements

(unaudited)

(dollars in thousands, except per share data)

1.  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, 2016.  In the opinion of management, the accompanying consolidated financial statements of the Company contain all adjustments necessary to fairly present its financial position as of June 30, 2017 and December 31, 2016, net income and comprehensive income for the three and six months ended June 30, 2017 and 2016, and cash flows for the six months ended June 30, 2017 and 2016.  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 consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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 and other than temporary impairment (OTTI) of financial instruments and the allowance for loan losses.

The accompanying unaudited consolidated financial statements include the accounts of the Company, West Bank and West Bank's wholly-owned subsidiary WB Funding Corporation.  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.

Current accounting developments:  In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606): Summary and Amendments that Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs—Contracts with Customers (Subtopic 340-40). The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the Codification. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2017. The guidance does not apply to revenues associated with financial instruments, including loans and investment securities. The Company does not expect the guidance to have a material impact on the Company's consolidated financial statements, as the most significant sources of revenue are excluded from the scope of Topic 606.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The update enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information by updating certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Among other changes, the update requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, and clarifies that entities should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entities' other deferred tax assets. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2017, and is to be applied on a modified retrospective basis. The Company is currently assessing the impact of this guidance, but does not expect the guidance to have a material impact on the Company's consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The guidance in the update supersedes the requirements in ASC Topic 840, Leases. The update will require business entities to recognize lease assets and liabilities for leases with lease terms of more than 12 months on their balance sheet and to disclose key information about leasing arrangements. A lessee would recognize a liability to make lease payments and a right-of-use asset representing its right to use the leased asset for the lease term. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis. The Company currently leases its main location and space for six other branch offices and operational departments under operating leases that will result in recognition of lease assets and lease liabilities on the consolidated balance sheets under the ASU. The amount of assets and liabilities added to the balance sheet are not expected to have a material impact on the Company's consolidated financial statements per preliminary estimates.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718). The update simplifies several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance also allows an entity to make an entity-wide accounting policy election to either estimate expected forfeitures or account for forfeitures as they occur. For public companies, the update was effective for annual periods beginning after December 15, 2016. Portions of the amended guidance were to be applied using a modified retrospective transition method, and others require prospective application. Upon adoption of this update on January 1, 2017, the Company made the accounting policy election to account for forfeitures as they occur. This resulted in no effect on the Company's consolidated financial statements, as prior stock-based compensation expense assumed no expected forfeitures. Also upon adoption, the Company changed the calculation of the assumed proceeds of the treasury stock method on a prospective basis to eliminate deferred taxes from the calculation. The net impact on the income statement is dependent upon the change in the Company's stock price from grant date to vesting date and cannot be predicted with any certainty. The requirement to report the excess tax benefit or shortfall related to settlements of share-based payment awards in earnings as an increase or decrease to tax expense has been applied to settlements occurring on or after January 1, 2017, and the impact of applying that guidance reduced reported income tax expense $244 for the six months ended June 30, 2017.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). The amendments in this update require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net carrying value at the amount expected to be collected on the financial assets. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount of financial assets. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis is determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are recorded as a credit loss expense for these assets. Off-balance-sheet arrangements such as commitments to extend credit, guarantees, and standby letters of credit that are not considered derivatives under ASC 815 and are not unconditionally cancellable are also within the scope of this update. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. For public companies, the update is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this update earlier as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. An entity will apply the amendments in this update on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is currently planning for the implementation of this accounting standard. It is too early to assess the impact that this guidance will have on the Company's consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in this update provide guidance for eight specific cash flow classification issues for which current guidance is unclear or does not exist, thereby reducing diversity in practice. For public companies, the update is effective for annual periods beginning after December 15, 2017, with early adoption permitted. The Company's early adoption of the update as of January 1, 2017, did not have a material impact on the Company's consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20). This update amends the amortization period for certain purchased callable debt securities held at a premium. The update shortens the premium's amortization period to the earliest call date. For public companies, the update is effective for annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis with a cumulative-effect adjustment directly to retained earnings as of the beginning of the adoption period. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company does not expect the guidance to have a material impact on the Company's consolidated financial statements.

2.  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 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 calculations of earnings per common share and diluted earnings per common share for the three and six months ended June 30, 2017 and 2016 are presented in the following table.

	Three Months Ended June 30,				Six Months Ended June 30,

The amortized cost and fair value of investment securities available for sale as of June 30, 2017, by contractual maturity, are shown below. Certain securities have call features that allow the issuer to call the securities prior to maturity.  Expected maturities may differ from contractual maturities for collateralized mortgage obligations, mortgage-backed securities and asset-backed securities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.  Therefore, collateralized mortgage obligations, mortgage-backed securities and asset-backed securities are not included in the maturity categories within the following maturity summary.

As of June 30, 2017, the available for sale and held to maturity securities with unrealized losses included 27 state and political subdivision securities, 25 collateralized mortgage obligation securities, four mortgage-backed securities, one trust preferred security and one corporate note. The Company believed the unrealized losses on investments available for sale and held to maturity as of June 30, 2017 were due to market conditions rather than reduced estimated cash flows. 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 as of June 30, 2017.

4. Loans and Allowance for Loan Losses

Loans consisted of the following segments as of June 30, 2017 and December 31, 2016.

	June 30, 2017			December 31, 2016
Commercial	$	315,098		$	334,014
Real estate:
Construction, land and land development	232,579			205,610
1-4 family residential first mortgages	50,362			47,184
Home equity	15,849			18,057
Commercial	814,755			788,000
Consumer and other loans	8,057			8,355
	1,436,700			1,401,220
Net unamortized fees and costs	(1,321		)	(1,350		)
	$	1,435,379		$	1,399,870

Real estate loans of approximately $680,000 were pledged as security for Federal Home Loan Bank (FHLB) advances as of June 30, 2017 and December 31, 2016.

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 past due 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 a troubled debt restructured (TDR) loan when the Company separately concludes that a borrower is experiencing financial difficulties and a concession is granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden of 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 also be reported as nonaccrual or past due 90 days 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 loans classified as Doubtful, Substandard and Watch according to the Company's classification criteria. These loans involve the anticipated potential for 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.

TDR loans totaled $360 and $426 as of June 30, 2017 and December 31, 2016, respectively, and were included in nonaccrual loans. There were no loan modifications considered to be TDR that occurred during the three and six months ended June 30, 2017 and 2016. The recorded investment in TDR loans that have been modified within the twelve months preceding June 30, 2017 and June 30, 2016, and that have subsequently had a payment default, totaled $0 and $20, respectively. A TDR loan is considered to have a payment default when it is past due 30 days or more.

The following table summarizes the recorded investment in impaired loans by segment, broken down by loans with no related allowance for loan losses and loans with a related allowance and the amount of that allowance as of June 30, 2017 and December 31, 2016.

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's financial condition is satisfactory and stable.  The borrower has satisfactory debt service capacity, and the loan is well secured. The loan is performing as agreed, and the financial characteristics and trends 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 flows 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 the borrower is not able to make scheduled principal and interest payments and any collateral securing the loan declines 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 five 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 of 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.  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 the current economic conditions that may affect the borrower's ability to pay.  Loans are charged-off against the allowance for loan losses when management believes that collectability of the principal is unlikely. 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.

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 the changes in the allowance for loan losses by segment for the three and six months ended June 30, 2017 and 2016.

5.  Long-Term Debt

On May 25, 2017, the Company entered into a credit agreement with a commercial bank and borrowed $25,000. This credit agreement replaced a prior credit agreement with the same commercial bank that had a remaining outstanding principal balance of $3,000. The additional borrowing was used to make a capital injection into the Company's subsidiary, West Bank. Principal and interest under the term note are payable quarterly over five years. The interest rate is variable at 1.95 percent over the 30-day LIBOR rate. The interest rate was 3.03 percent at June 30, 2017. In the case of an event of default, the unaffiliated commercial bank may accelerate the payment of the loan. The loan is secured by 100 percent of the stock of West Bank.

6. Derivatives

The Company has entered into various forward-starting interest rate swap transactions to effectively convert variable rate FHLB advances and junior subordinated notes to fixed rate debt as of forward-starting dates. The swap transactions were designated as cash flow hedges. Interest rate swaps with a total notional amount of $70,000 were terminated in 2015, subject to termination fees totaling $541. The termination fees are being reclassified from accumulated other comprehensive income to interest expense over the remaining life of the underlying cash flows through June 2020. An interest rate swap with a notional amount of $30,000 became effective in December 2015. Another interest rate swap, with a notional amount of $20,000, has a forward-starting date in September 2018. No amount of ineffectiveness was included in net income for the six months ended June 30, 2017 or 2016, and the Company estimates there will be approximately $426 of cash payments and reclassification from accumulated other comprehensive income to interest expense through the 12 months ended June 30, 2018. 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. As of June 30, 2017 and December 31, 2016, the Company pledged $470 and $470, respectively, of collateral to the counterparty in the form of cash on deposit with a third party. The Company's counterparty was required to pledge $830 and $1,070 at June 30, 2017 and December 31, 2016, respectively.

The table below identifies the balance sheet category and fair values of the Company's derivative instruments designated as cash flow hedges as of June 30, 2017 and December 31, 2016.

Interest Rate Swap	Notional Amount		Fair Value			Balance Sheet Category	Weighted Average Receive Rate		Weighted Average Pay Rate		Maturity
June 30, 2017
Interest rate swap	$	30,000	$	(447	)	Other Liabilities	1.46	%	2.52	%	9/21/2020
Interest rate swap(1)	20,000		840			Other Assets	—		4.81	%	9/30/2026
December 31, 2016
Interest rate swap	30,000		(496		)	Other Liabilities	1.30	%	2.52	%	9/21/2020
Interest rate swap(1)	20,000		1,068			Other Assets	—		4.81	%	9/30/2026

(1) This swap is a forward starting swap with a weighted average pay rate of 4.81 percent beginning September 30, 2018. No interest payments are required related to this swap until December 30, 2018.

The following table identifies the pre-tax losses recognized on the Company's derivative instruments designated as cash flow hedges for the six months ended June 30, 2017 and 2016.

9.  Commitments and Contingencies

Financial instruments with off-balance-sheet risk: 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 consisted of the following approximate amounts as of June 30, 2017 and December 31, 2016. 

	June 30, 2017		December 31, 2016
Commitments to extend credit	$	575,955	$	614,681
Standby letters of credit	4,407		5,487
	$	580,362	$	620,168

West Bank previously executed Mortgage Partnership Finance (MPF) Master Commitments (Commitments) with the FHLB of Des Moines to deliver residential 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 residential mortgage loans. At June 30, 2017, 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 $156. The outstanding balance of mortgage loans sold under the MPF Program was $102,986 and $112,084 at June 30, 2017 and December 31, 2016, respectively.

Contractual commitments: The Company has remaining commitments to invest in qualified affordable housing projects totaling $6,447 and $5,768 as of June 30, 2017 and December 31, 2016, respectively.

Contingencies: Neither the Company nor West Bank is a party, and no property of these entities is subject, to any material pending legal proceedings, other than ordinary routine litigation incidental to West Bank's business. The Company does not know of any proceeding contemplated by a governmental authority against the Company or West Bank.

10. Fair Value Measurements

Accounting guidance on fair value measurements and disclosuresdefines fair value and establishes a framework for measuring the fair value of assets and liabilities using a hierarchy system.  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 investment 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 six months ended June 30, 2017.

The following is a description of valuation methodologies used for financial assets and liabilities recorded at fair value on a recurring basis.

Investment 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 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, asset-backed securities, state and political subdivision securities, and trust preferred securities. The Company currently holds no investment securities classified as Level 3.

Generally, management obtains the fair value of investment securities at the end of each reporting period via a third-party pricing service. Management reviewed the valuation process used by the third party and believed that process was valid. On a quarterly basis, the Company tests the fair values by selecting a sample of investment securities from each category of securities, obtaining pricing from an independent investment portfolio management firm and comparing the two sets of fair values. Any significant variances are reviewed and investigated. For a sample of securities, prices are further validated by management, with assistance from an independent investment portfolio management 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 the investment securities were properly classified in the fair value hierarchy as of the end of the period covered by this report.

Derivative instruments: The Company's derivative instruments consist of interest rate swaps, which are accounted for as cash flow hedges. The Company's derivative positions are classified within Level 2 of the fair value hierarchy and are 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 derivatives are 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.

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).  As of both June 30, 2017 and December 31, 2016, impaired loans for which a fair value adjustment was recorded were recorded at a net value of $0.  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.  The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate.  Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. 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 and may be discounted based on management's opinions concerning market developments or the client's business.

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 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:  The carrying amount approximates fair value.

Investment securities held to maturity: The fair values of these securities, which are all state and political subdivisions, are determined by the same method previously described for investment securities available for sale.

FHLB stock:  The fair value of this restricted stock is estimated at its carrying value and redemption price of $100 per share.

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 values 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 time deposits are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered on time deposits with similar terms.

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, short-term borrowings, variable rate FHLB advances, and variable rate long-term borrowings approximate their fair values.  Fair values of subordinated notes, a fixed rate FHLB advance 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.

Certain statements in this report, other than purely historical information, including estimates, projections, statements relating to the Company's business plans, objectives and expected operating results, and the assumptions upon which those statements are based, are “forward-looking statements” within the meanings of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act). Forward-looking statements may appear throughout this report. These forward-looking statements are generally identified by the words “believes,” “expects,” “intends,” “anticipates,” “projects,” “future,” “may,” “should,” “will,” “strategy,” “plan,” “opportunity,” “will be,” “will likely result,” “will continue” or similar references, or references to estimates, predictions or future events.  Such forward-looking statements are based upon certain underlying assumptions, risks and uncertainties.  Because of the possibility that the underlying assumptions are incorrect or do not materialize as expected in the future, actual results could differ materially from these forward-looking statements.  Risks and uncertainties that may affect future results include: interest rate risk; competitive pressures; pricing pressures on loans and deposits; changes in credit and other risks posed by the Company's loan and investment portfolios, including declines in commercial or residential real estate values or changes in the allowance for loan losses dictated by new market conditions or regulatory requirements; actions of bank and nonbank competitors; changes in local, national and international economic conditions; changes in regulatory requirements, limitations and costs; changes in customers' acceptance of the Company's products and services; cyber-attacks; unexpected outcomes of existing or new litigation involving the Company; and any other risks described in the “Risk Factors” sections of this and other reports filed by the Company with the Securities and Exchange Commission. The Company undertakes no obligation to revise or update such forward-looking statements to reflect current or future events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.

CRITICAL ACCOUNTING POLICIES

The discussion and analysis of the Company's financial condition and results of operations are based upon the Company's consolidated financial statements that have been prepared in accordance with GAAP. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, income and expenses. These estimates are based upon historical experience and on various other assumptions that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The estimates and judgments that management believes have the most effect on the Company's reported financial position and results of operations are described as critical accounting policies in the Company's Annual Report on Form 10-K for the year ended December 31, 2016, as filed with the Securities and Exchange Commission on March 1, 2017. There have been no significant changes in the critical accounting policies or the assumptions and judgments utilized in applying these policies since the year ended December 31, 2016.

NON-GAAP FINANCIAL MEASURES

This report contains references to financial measures that are not defined in GAAP. Such non-GAAP financial measures include the Company’s presentation of net interest income and net interest margin on a fully tax-equivalent (FTE) basis, and the presentation of the efficiency ratio on an FTE basis and excluding certain income and expenses. Management believes these non-GAAP financial measures provide useful information to both management and investors to analyze and evaluate the Company’s financial performance. Limitations associated with non-GAAP financial measures include the risks that persons might disagree as to the appropriateness of items included in these measures and that different companies might calculate these measures differently. These non-GAAP disclosures should not be considered an alternative to the Company’s GAAP results. The following table reconciles the non-GAAP financial measures of net interest income, net interest margin and efficiency ratio on an FTE basis to GAAP.

(1) Computed on a tax-equivalent basis using an incremental federal income tax rate of 35 percent, adjusted to reflect the effect of the nondeductible interest expense associated with owning tax-exempt securities and loans.

(2) Efficiency ratio expresses noninterest expense as a percent of fully taxable-equivalent net interest income and noninterest income, excluding specific noninterest income and expenses. Management believes the presentation of this non-GAAP measure provides supplemental useful information for proper understanding of the financial results, as it enhances the comparability of income and expenses arising from taxable and nontaxable sources.

THREE AND SIX MONTHS ENDED JUNE 30, 2017

OVERVIEW

The following discussion describes the consolidated operations and financial condition of the Company, West Bank and West Bank's wholly owned subsidiary WB Funding Corporation. Results of operations for the three and six months ended June 30, 2017 are compared to the results for the same periods in 2016, and the consolidated financial condition of the Company as of June 30, 2017 is compared to December 31, 2016. The Company operates in three markets: central Iowa, which is generally the greater Des Moines metropolitan area; eastern Iowa, which is the area including and surrounding Iowa City and Coralville, Iowa; and the Rochester, Minnesota area.

Net income for the three months ended June 30, 2017 was $6,365, or $0.39 per diluted common share, compared to $5,476, or $0.34 per diluted common share for the three months ended June 30, 2016. The Company's annualized return on average assets and return on average equity for the three months ended June 30, 2017 were 1.33 and 14.86 percent, respectively, compared to 1.22 and 13.90 percent, respectively, for the three months ended June 30, 2016.

Management's Discussion and Analysis

(in thousands, except share and per share data)

The increase in net income for the three months ended June 30, 2017 compared to the same period in 2016 was primarily due to higher net interest income associated with loan growth that exceeded the increase in interest expense on deposits, a decrease in the provision for loan losses and an increase in noninterest income. Partially offsetting these positive changes for the three months ended June 30, 2017 compared to the three months ended June 30, 2016 was a 4.5 percent increase in noninterest expense.

Net interest income for the three months ended June 30, 2017 grew $820, or 5.7 percent, compared to the three months ended June 30, 2016. The increase in net interest income was driven by a $129,425, or 9.7 percent, increase in average loans outstanding for the three months ended June 30, 2017 compared to the same time period in 2016. Partially offsetting the increase in interest income was an increase of $957 in interest expense on deposits, primarily due to higher interest rates paid on certain deposit products. The Company recorded no provision for loan losses for the three months ended June 30, 2017 compared to a $500 provision in the three months ended June 30, 2016. Despite no provision for loan losses in the three months ended June 30, 2017, the allowance for loan losses grew $59 during that time period as a result of net recoveries on previously charged off loans.

Noninterest income grew $413, or 21.7 percent, during the three months ended June 30, 2017 compared to the same time period in 2016, mainly due to net gains on sales of investment securities, an increase in trust revenue and a nonrecurring gain on an asset sale.

Net income for the six months ended June 30, 2017 was $12,471, or $0.76 per diluted common share compared to $11,172, or $0.69 per diluted common share, for the six months ended June 30, 2016. The Company's annualized return on average assets and return on average equity for the six months ended June 30, 2017 were 1.34 and 14.83 percent, respectively, compared to 1.27 and 14.33 percent, respectively, for the first six months of 2016.

The increase in net income for the six months ended June 30, 2017 compared to the same period in 2016 was primarily due to growth in net interest income associated with loan growth that exceeded the increase in interest expense on deposits, a decrease in the provision for loan losses and an increase in noninterest income. Partially offsetting these positive changes for the first six months of 2017 compared to the first six months of 2016 was a 3.8 percent increase in noninterest expense.

Net interest income for the six months ended June 30, 2017 grew $1,510, or 5.4 percent, compared to the six months ended June 30, 2016. The increase in net interest income was primarily due to the $147,437 increase in average loans outstanding for the first six months of 2017 compared to the first six months of 2016. During the six months ended June 30, 2017, interest expense on deposits increased $1,447 compared to the six months ended June 30, 2016, mainly due to increased interest rates on certain money market deposit products and certificates of deposit as a result of rising market rates. The Company recorded no provision for loan losses for the six months ended June 30, 2017 compared to a $700 provision in the six months ended June 30, 2016. During the six months ended June 30, 2017, the allowance for loan losses grew $374 as a result of net recoveries on previously charged off loans.

Noninterest income increased $343, or 8.3 percent, during the six months ended June 30, 2017 compared to the six months ended June 30, 2016, mainly due to net gains on sales of investment securities, an increase in trust revenue and a nonrecurring gain on an asset sale.

Total loans outstanding increased $35,509, or 2.5 percent, during the first six months of 2017. Total loans outstanding declined $11,356 between March 31, 2017 and June 30, 2017, primarily due to some loan payoffs in the second quarter. Management believes the loan pipeline is strong and that loan growth will continue in all three of our markets during the remainder of 2017. The credit quality of the loan portfolio remained strong as evidenced by the Company's Texas ratio, which was 0.43 percent as of June 30, 2017. As of June 30, 2017, the allowance for loan losses was 1.15 percent of outstanding loans, and management believed the allowance was adequate to absorb any losses inherent in the loan portfolio.

On May 25, 2017, the Company entered into a credit agreement with an unaffiliated commercial bank and borrowed $25,000. This credit agreement replaced a prior credit agreement that had a remaining outstanding principal balance of $3,000. The additional borrowing was used to make a capital injection into the Company's subsidiary, West Bank. In addition, the Company previously owned four banking offices that it leased to West Bank. On May 30, 2017, the Company sold those offices to West Bank for approximately $18,000, which amount was also injected into the capital of West Bank. The additional capital increased West Bank's lending limit to any single customer by $6,000, which allows for expanded loan growth.

Management's Discussion and Analysis

(in thousands, except share and per share data)

Each quarter throughout the year, the Company's four key performance metrics are compared to those of our identified peer group of 16 companies. The group of 16 Midwestern, publicly traded peer financial institutions against which we compare our performance each quarter consists of BankFinancial Corporation, Farmers Capital Bank Corporation, First Business Financial Services, First Defiance Financial Corp., First Mid-Illinois Bancshares, Inc., Hills Bancorporation, Horizon Bancorp, Isabella Bank Corporation, Mercantile Bank Corporation, MidWestOne Financial Group, Inc., MutualFirst Financial, Inc., Nicolet Bankshares, Inc., Peoples Bancorp, QCR Holdings, Inc., Southwest Bancorp and Waterstone Financial, Inc. The members of the peer group are selected based on their business focus, scope and location of operations, size and other considerations. The Company is in the middle of the group in terms of asset size. The group is periodically reviewed, with changes made primarily to reflect merger and acquisition activity. Our goal is to perform at or near the top of these peers relative to what we consider to be four key metrics: return on average assets, return on average equity, efficiency ratio and Texas ratio. We believe these measures encompass the factors that define the performance of a community bank. When contrasted with the peer group's metrics for the three months ended March 31, 2017 (latest data available), the Company's metrics for the six months ended June 30, 2017 were better than those of each company in the peer group as shown in the table below, except for one peer that had a higher return on average assets.

	West Bancorporation, Inc.	Peer Group Range
	Six months ended June 30, 2017	Three months ended March 31, 2017
Return on average assets	1.34%	0.47% - 1.52%
Return on average equity	14.83%	3.66% - 12.63%
Efficiency ratio*(1)	46.38%	54.45% - 75.30%
Texas ratio*	0.43%	3.68% - 22.87%

* A lower ratio is more desirable.

(1) The efficiency ratio is a non-GAAP measure. For further information, refer to the Non-GAAP Financial Measures section of this report.

In May 2017, the Company was included on the American Bankers Association's 2016 annual list of the top 200 publicly traded community banks. The ranking was based on three-year average return on equity. The Company was listed as #9 in the nation.

At its meeting on July 26, 2017, the Board of Directors of the Company declared a quarterly dividend of $0.18 per common share. The dividend is payable on August 23, 2017, to stockholders of record as of August 9, 2017. The dividend was increased by $0.01 to the $0.18 level for the dividend declared in April 2017 and represents the highest quarterly dividend ever paid by the Company.

(1) Average loan balances include nonaccrual loans.  Interest income recognized on nonaccrual loans has been included.

(2) Interest income on loans includes amortization of loan fees and costs and prepayment penalties collected, which are not material.

(3) Tax-exempt income has been adjusted to a tax-equivalent basis using an incremental federal income tax rate of 35 percent and is adjusted to reflect the effect of the nondeductible interest expense associated with owning tax-exempt investment securities and loans.

(4) Net interest income (FTE) and net interest margin (FTE) are non-GAAP measures. For further information, refer to the Non-GAAP Financial Measures section of this report.

The Company's largest component of net income is net interest income, which is the difference between interest earned on interest-earning assets, consisting primarily of loans and investment securities, and interest paid on interest-bearing liabilities, consisting of deposits and borrowings. Fluctuations in net interest income can result from the combination of changes in the average balances of asset and liability categories and changes in interest rates. Interest rates earned and paid are affected by general economic conditions, particularly changes in market interest rates, and by competitive factors, government policies and actions of regulatory authorities. The Board of Governors of the Federal Reserve System increased the targeted federal funds interest rate by 25 basis points in December 2016, March 2017 and June 2017.

Net interest margin is a measure of the net return on interest-earning assets and is computed by dividing annualized tax-equivalent net interest income by total average interest-earning assets for the period. The net interest margin for the three and six months ended June 30, 2017 declined eight and six basis points, respectively, compared to the three and six months ended June 30, 2016. The primary drivers of the decline in the net interest margin were an increase in interest rates paid on certain deposit categories and an increase in the variable rates paid on other borrowed funds, partially offset by an increase in yield on loans and investment securities. Despite the decline in the net interest margin, tax-equivalent net interest income for the three and six months ended June 30, 2017 increased $759 and $1,370, respectively, compared to the same time periods in 2016. The increase in net interest income for the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016 was largely due to the increase in average outstanding loans. Management expects the current interest rate environment to continue to put pressure on the net interest margin throughout the remainder of 2017. Management continually develops and applies strategies to attempt to maintain the net interest margin.

Tax-equivalent interest income on loans increased $1,708 for the three months ended June 30, 2017 compared to the three months ended June 30, 2016. For the six months ended June 30, 2017, tax-equivalent interest income on loans increased $3,196 compared to the same time period in 2016. The improvement for both time periods was due to the increase in average loan balances outstanding. The average yields on loans increased by seven and one basis points, respectively, for the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016. The Company continues to focus on expanding existing and entering into new customer relationships while maintaining strong credit quality. The yield on the Company's loan portfolio is affected by the mix of the loans in the portfolio, the interest rate environment, the effects of competition, the level of nonaccrual loans and reversals of previously accrued interest on charged-off loans. The political and economic environments can also influence the volume of new loan originations and the mix of variable rate versus fixed rate loans.

The average balance of investment securities was lower during the three and six months ended June 30, 2017 than during the same periods in 2016. Significant purchase activity occurred late in the second quarter of 2017, which exceeded the proceeds from sales and principal paydowns during the six months ended June 30, 2017. In certain cases, securities were sold and the funds were invested in securities with higher rates while slightly extending the duration of the portfolio, which is expected to improve the yield on the investment portfolio in future periods. The overall portfolio yield increased 29 and 22 basis points, respectively, for the three and six months ended June 30, 2017 compared to the same periods last year.

The average balance of interest-bearing demand, savings and money market deposits increased for the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016, partially due to an increase in average balances of money market accounts, including public funds from municipalities. In addition, approximately $76 million of noninterest-bearing accounts were reclassified to interest-bearing accounts in April 2017 as part of a retail deposit product restructuring in which we realigned and simplified the retail checking account products provided to our customers. The average rate paid on interest-bearing demand, savings and money market deposits for the three and six months ended June 30, 2017 increased 27 and 23 basis points, respectively, compared to the three and six months ended June 30, 2016. The increase in interest expense was primarily due to increasing interest rates on certain money market deposit products in response to the Federal Reserve System's rate increases. The average balance of time deposits increased for the three and six months ended June 30, 2017 compared to the same periods in 2016. The increase was primarily due to the shift of demand and savings account balances to higher interest rate time deposits. Interest rates on time deposits increased 23 and 19 basis points for the three and six months ended June 30, 2017 compared to the same periods in 2016, primarily due to higher market interest rates paid at the time new and renewed time deposits were issued.

The average rate paid on other borrowed funds increased 51 and 32 basis points, respectively, for the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016. The increase in the average rate paid was due to increases in rates for variable rate FHLB advances, the subordinated note and long-term debt. Interest expense is expected to increase, as the Company borrowed an additional $22,000 in May 2017.

Provision for Loan Losses and the Related Allowance for Loan Losses

The provision for loan losses represents charges made to earnings to maintain an adequate allowance for loan losses.  The adequacy of the allowance for loan losses is evaluated quarterly by management and reviewed by the Board of Directors. The allowance for loan losses is management's best estimate of probable losses inherent in the loan portfolio as of the balance sheet date.  Based upon the evaluation, no provision was recorded for either the three or six months ended June 30, 2017, as recoveries on previously charged off loans during the periods were sufficient to increase the allowance for loan losses to a level deemed appropriate in relation to the 2017 year-to-date loan growth and credit quality. The provision for loan losses for the three and six months ended June 30, 2016 was $500 and $700, respectively.

Factors considered in establishing an appropriate allowance include: the borrower's financial condition; the value and adequacy of loan collateral; the condition of the local economy and the borrower's specific industry; the levels and trends of loans by segment; and a review of delinquent and classified loans.  The quarterly evaluation focuses on factors such as specific loan reviews, changes in the components of the loan portfolio given the current and forecasted economic conditions, and historical loss experience.  Any one of the following conditions may result in the review of a specific loan: concern about whether the customer's cash flow or net worth is sufficient to repay the loan; delinquency status; criticism of the loan in a regulatory examination; the suspension of interest accrual; or other factors, including whether the loan has other special or unusual characteristics that suggest special monitoring is warranted. The Company's concentration risks include geographic concentration in central and eastern Iowa and southeastern Minnesota. The local economies are composed primarily of service industries and state and county governments.

West Bank has a significant portion of its loan portfolio in commercial real estate loans, commercial lines of credit, commercial term loans, and construction and land development loans.  West Bank's typical commercial borrower is a small- or medium-sized, privately owned business entity.  West Bank's commercial loans typically have greater credit risks than residential mortgages or consumer loans because they often have larger balances and repayment usually depends on the borrowers' successful business operations.  Commercial loans also involve additional risks because they generally are not fully repaid over the loan period and, thus, may require refinancing or a large payoff at maturity.  When the economy turns downward, commercial borrowers may not be able to repay their loans, and the value of their assets, which are usually pledged as collateral, may decrease rapidly and significantly. 

While management uses available information to recognize losses on loans, further reduction in the carrying amounts of loans may be necessary based on changes in circumstances, changes in the overall economy in the markets we currently serve, or later acquired information.  Identifiable sectors within the general economy are subject to additional volatility, which at any time may have a substantial impact on the loan portfolio.  In addition, regulatory agencies, as integral parts of their examination processes, periodically review the credit quality of the loan portfolio and the level of the allowance for loan losses.  Such agencies may require West Bank to recognize additional losses based on such agencies' review of information available to them at the time of their examinations.

West Bank's policy is to charge off loans when, in management's opinion, a loan or a portion of a loan is deemed uncollectible. Concerted efforts are made to maximize subsequent recoveries.  The following table summarizes the activity in the Company's allowance for loan losses for the three and six months ended June 30, 2017 and 2016 and related ratios.

In general, the U.S. economy is growing, but at a slower rate than was considered normal before the financial crisis. Average monthly job growth in 2017 has stayed near 200,000, while the national unemployment rate has declined slightly to 4.4 percent as of June 30, 2017, the lowest level since May 2007. Activity in the housing market continues at a moderate pace. Interest rates are expected to continue to gradually rise. The economic environments in Iowa and Minnesota continue to improve. Based on the current economic indicators, the Company decided to maintain the economic factors within the allowance for loan losses evaluation at the same levels used in 2016. In the first six months of 2017, the Company continued to use experience factors based on the highest losses calculated over a rolling 12-, 16-, or 20-quarter period. Loan growth in the first six months of 2017 resulted in the portion of the allowance for loan losses related to loans collectively evaluated for impairment to increase $464 to a total of $16,073, or 1.12 percent, as of June 30, 2017 compared to $15,609, or 1.11 percent, as of December 31, 2016. Management believed the resulting allowance for loan losses as of June 30, 2017 was adequate to absorb any losses inherent in the loan portfolio at the end of the quarter.

The slight increase in service charges on deposit accounts for the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016 was driven by the March and April 2017 realignment and simplification of the retail checking account products provided to our customers. We expect to see further increases in the retail service charge income for the remainder of 2017, but we cannot predict how customers may modify their banking behavior in response to the change in checking account terms related to the product realignment. During the three and six months ended June 30, 2017, nonsufficient funds fees declined $30 and $53, respectively, compared to the same time periods in 2016, consistent with the trend of the past several years.

Revenue from trust services was higher during the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016 due to the combination of a higher amount of one-time estate fees and asset growth through ongoing business development efforts.

Gain from bank-owned life insurance was recognized for both the six months ended June 30, 2017 and 2016, but not during the three months ended June 30, 2017 and 2016.

The Company recognized net gains on sales of investment securities in the three and six months ended June 30, 2017, as the Company took advantage of the opportunity to sell various types of investment securities available for sale at gains and reinvested the proceeds in higher yielding securities with similar risk profiles and slightly longer durations.

Although the Company's agreement to purchase State of Iowa wind energy tax credits at a discount ended effective May 1, 2017, total revenue from discounts on purchased transferable income tax credits increased for the three and six months ended June 30, 2017 compared to the same time periods in 2016. During the three months ended June 30, 2017, the Company entered into agreements to purchase other discounted transferable State of Iowa income tax credits and expects to recognize total income from discounts of approximately $153 for the year ended December 31, 2017.

Gain on sale of other assets for the three and six months ended June 30, 2017 included a nonrecurring gain related to a final payment received from the 2015 sale of SmartyPig, LLC.

When compared with the three and six months ended June 30, 2016, occupancy costs increased for the three and six months ended June 30, 2017, partially as the result of operating costs associated with the new Rochester, Minnesota, office, which opened in November 2016. Also impacting the increase in occupancy costs compared to the prior year was a first quarter 2016 one-time reversal of previously accrued rent related to the terms of the previous lease for the Waukee, Iowa, branch facility at the time the branch was acquired in February 2016.

The increase in data processing expense for the three and six months ended June 30, 2017 compared to the same time periods in 2016 was primarily because of costs associated with upgrading credit analysis software, one-time costs associated with revising the retail checking account products, ongoing implementation of security enhancements, and an annual-inflation-rate-based contractual increase in fees paid to our core applications systems service provider.

FDIC insurance expense declined for the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016. The FDIC assessment rate calculation includes a series of risk-based factors. As a result of the May 2017 capital injection of $40,000 into West Bank, the capital ratio component improved enough to reduce the assessment rate to the minimum level established by the FDIC. Management believes the assessment rate will remain at the minimum level throughout the remainder of 2017.

Professional fees increased for the three and six months ended June 30, 2017 compared to the same time period in 2016, chiefly due to increased costs associated with preparation and adoption of the West Bancorporation, Inc. 2017 Equity Incentive Plan and filing a new shelf registration statement with the Securities and Exchange Commission (which allows us to issue more publicly traded equity and debt instruments), and due to ongoing legal fees at West Bank.

The increase in marketing expense for the three and six months ended June 30, 2017 compared to the three and six months ended June 30, 2016 was primarily due to costs associated with the retail checking account product updates.

Investment advisory fees declined for the three and six months ended June 30, 2017 as contrasted with the same time periods in 2016 mainly as a result of bringing the administration of the investment portfolio in-house, effective October 1, 2016. The Company also pays an administrative fee to an investment management firm for assisting with the purchase and administration of public company floating rate commercial loans. That administrative fee has declined as the result of holding a lower level of those loans.

All other expenses declined for the three and six months ended June 30, 2017 compared to the same periods in 2016 due to the elimination of certain costs related to a retail deposit product, and first quarter 2016 included a one-time cost associated with a bank-owned life insurance claim.

Income Tax Expense

The Company recorded income tax expense of $2,872 (31.1 percent of pre-tax income) and $5,272 (29.7 percent of pre-tax income) for the three and six months ended June 30, 2017, respectively, compared with $2,381 (30.3 percent of pre-tax income) and $4,615 (29.2 percent of pre-tax income) for the three and six months ended June 30, 2016. The Company's consolidated income tax rate differs from the federal statutory income tax rate, primarily due to tax-exempt interest income, the tax-exempt increase in cash value of bank-owned life insurance, tax-exempt gain on bank-owned life insurance, disallowed interest expense, and state income taxes.

Two other items significantly impacted the effective tax rate for the six months ended June 30, 2017 compared to the six months ended June 30, 2016. The adoption of ASU No. 2016-09, Compensation—Stock Compensation (Topic 718), effective January 1, 2017, simplified the recording of income taxes related to vesting of equity compensation. The impact of an increase in the fair value of restricted stock over the vesting period is now recorded as a reduction in income tax expense rather than as additional paid-in capital. During the six months ended June 30, 2017, a tax benefit of $244 was recorded as a result of this change in accounting method. By comparison, the tax benefit recorded in additional paid-in capital for the six months ended June 30, 2016 was $77. The tax rate for the first six months of 2017 and 2016 was also impacted by year-to-date federal low income housing tax credits of approximately $205 and $175, respectively.

FINANCIAL CONDITION

The Company had total assets of $1,917,587 as of June 30, 2017, an increase of 3.42 percent compared to total assets as of December 31, 2016. The most significant changes in the balance sheet were increases in investment securities available for sale, loans, deposits, short-term borrowings and long-term debt, and a decline in cash and cash equivalents. A summary of changes in the balance sheet components is provided below.

Investment Securities

The balance of investment securities available for sale increased by $61,960 during the six months ended June 30, 2017. State and political subdivision securities increased $26,977, corporate notes increased $18,184, and government agency guaranteed collateralized mortgage obligations, mortgage-backed securities and asset-backed securities increased by a total amount of $16,467 during the six months ended June 30, 2017. The Company purchased $138,436 of investment securities available for sale during the six months ended June 30, 2017. Securities sold totaled $53,020, and the proceeds were primarily reinvested in higher yielding securities that have a similar risk profile. The remaining purchases included the reinvestment of normal principal paydowns, calls and maturities, as well as investing the growth in deposits. The overall mix of the investment portfolio did not change significantly as a result of this activity.

As of June 30, 2017, approximately 62 percent of the available for sale investment securities portfolio consisted of government agency guaranteed collateralized mortgage obligations, mortgage-backed securities and asset-backed securities. Management believes these securities provide relatively good yields, have little to no credit risk and provide fairly consistent cash flows.

Loans and Nonperforming Assets

Loans outstanding increased $35,509, from $1,399,870 as of December 31, 2016 to $1,435,379 as of June 30, 2017. Growth in the loan portfolio during the first six months of 2017 was primarily the result of increases of $26,969 in construction loans and $26,755 in commercial real estate loans. This growth was partially offset by a decrease of $18,916 in commercial loans that included a $15,083 reduction in public company floating rate loans purchased from a third-party asset manager. The Company continues to focus on business development efforts in all of its markets. While some payoffs occurred in the second quarter of 2017, management believes loan growth will continue in all three of our markets during the remainder of 2017.

Credit quality of the Company's loan portfolio remains strong and stable. The Company's Texas ratio, which is computed by dividing total nonperforming assets by tangible common equity plus the allowance for loan losses, was 0.43 percent as of June 30, 2017, compared to 0.56 percent as of December 31, 2016. The ratio for both dates was significantly better than the March 31, 2017 peer group average (latest data available), which was approximately 9.01 percent, according to data in the March 2017 Bank Holding Company Performance Report prepared by the Division of Supervision and Regulation of the Federal Reserve.

The following table sets forth the amount of nonperforming assets held by the Company and common ratio measurements of those assets as of the dates shown. 

	June 30, 2017			December 31, 2016			Change
Nonaccrual loans	$	817		$	1,022		$	(205	)
Loans past due 90 days and still accruing interest	—			—			—
Troubled debt restructured loans (1)	—			—			—
Total nonperforming loans	817			1,022			(205		)
Other real estate owned	—			—			—
Total nonperforming assets	$	817		$	1,022		$	(205	)
Nonperforming loans to total loans	0.06		%	0.07		%	(0.01		)%
Nonperforming assets to total assets	0.04		%	0.06		%	(0.02		)%

(1) 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 are categorized as nonaccrual. There were two TDR loans as of June 30, 2017, and December 31, 2016, with aggregate balances of $360 and $426, respectively, categorized as nonaccrual.

Management's Discussion and Analysis

(in thousands, except share and per share data)

Deposits

Deposits increased $28,470 during the first six months of 2017, or 1.84 percent, compared to December 31, 2016.  Interest-bearing demand accounts increased $57,229, and noninterest-bearing demand accounts declined $93,065, from December 31, 2016 to June 30, 2017. Savings deposits, which include money market and insured cash sweep money market accounts, increased $21,653 from December 31, 2016 to June 30, 2017. Approximately $76,000 of noninterest-bearing accounts were reclassified to interest-bearing accounts in April 2017 as part of a retail deposit product restructuring. Other balance fluctuations were primarily due to normal customer activity, as corporate customers' liquidity needs vary at any given time. Total time deposits increased $42,653 during the first six months of 2017, primarily due to customers moving balances from demand and savings accounts to higher interest rate time deposits. As of June 30, 2017, a significant related party relationship maintained total deposit balances with West Bank of approximately $141,000.

Borrowings

Short-term borrowings, in the form of overnight funding, increased to $14,000 as of June 30, 2017 from $0 as of December 31, 2016. The need for overnight funding is primarily dependent on corporate customer deposit fluctuations, loan fundings and loan repayments.

Long-term debt increased $20,347 during the first six months of 2017. On May 25, 2017, the Company entered into a credit agreement with a commercial bank and borrowed $25,000. This credit agreement replaced a prior credit agreement with the same commercial bank that had a remaining balance of $3,000. The additional borrowing was used to make a capital injection into the Company's subsidiary, West Bank. Principal and interest under the term note are payable quarterly over five years. The interest rate is variable at 1.95 percent over the 30-day LIBOR rate. The interest rate was 3.03 percent at June 30, 2017.

Liquidity and Capital Resources

The objectives of liquidity management are to ensure the availability of sufficient cash flows to meet all financial commitments and to capitalize on opportunities for profitable business expansion.  The Company's principal source of funds is deposits.  Other sources include loan principal repayments, proceeds from the maturity and sale of investment securities, principal payments on collateralized mortgage obligations and mortgage-backed securities, federal funds purchased, advances from the FHLB, and funds provided by operations.  Liquidity management is conducted on both a daily and a long-term basis.  Investments in liquid assets are adjusted based on expected loan demand, projected loan and investment securities maturities and payments, expected deposit flows and the objectives set by the Company's asset-liability management policy. The Company had liquid assets (cash and cash equivalents) of $46,786 as of June 30, 2017 compared with $76,836 as of December 31, 2016.

As of June 30, 2017, West Bank had additional borrowing capacity available from the FHLB of approximately $282,000, as well as $67,000 through unsecured federal funds lines of credit with correspondent banks.  Net cash from operating activities contributed $14,599 to liquidity for the six months ended June 30, 2017.  Management believed that the combination of high levels of potentially liquid assets, cash flows from operations, and additional borrowing capacity provided the Company with strong liquidity as of June 30, 2017.

The Company's total stockholders' equity increased to $174,886 at June 30, 2017 from $165,376 at December 31, 2016.  The increase was primarily the result of net income less dividends paid, and an increase in accumulated other comprehensive income.

At June 30, 2017, the Company's tangible common equity as a percent of tangible assets was 9.12 percent compared to 8.92 percent as of December 31, 2016.

The Company and West Bank are subject to various regulatory capital requirements administered by federal and state banking agencies.  Failure to meet minimum capital requirements (as shown in the following table) can result in certain mandatory and possibly additional discretionary actions by regulators, which, if undertaken, could have a direct material effect on the Company's consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and West Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company's and West Bank's capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Management believed the Company and West Bank met all capital adequacy requirements to which they were subject as of June 30, 2017.

On January 1, 2015, the Company and West Bank became subject to the rules of the Basel III regulatory capital framework and related Dodd-Frank Wall Street Reform and Consumer Protection Act changes. The new rules included the implementation of a capital conservation buffer that is added to the minimum requirements for capital adequacy purposes. The capital conservation buffer is subject to a three year phase-in period that began on January 1, 2016 and will be fully phased-in on January 1, 2019 at 2.5 percent. The required phase-in capital conservation buffer during 2017 is 1.25 percent. A banking organization with a conservation buffer of less than the required amount will be subject to limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. At June 30, 2017, the ratios for the Company and West Bank were sufficient to meet the fully phased-in conservation buffer.

West Bancorporation, Inc.

Management's Discussion and Analysis

(in thousands, except share and per share data)

In late May 2017, the Company made a capital injection into the Company's subsidiary, West Bank, funded by entering into a $25,000 credit agreement with an unaffiliated commercial bank (see Note 5 to the Consolidated Financial Statements) and selling four bank buildings to West Bank for $18,000. The four bank buildings were properties the Company had previously owned and leased to West Bank. The new credit agreement replaced a prior credit agreement that had a remaining outstanding balance of $3,000, for net loan proceeds of $22,000. In total, $40,000 was added to West Bank's capital.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of earnings volatility that results from adverse changes in interest rates and market prices. The Company's market risk is primarily interest rate risk arising from its core banking activities of lending and deposit taking. Interest rate risk is the risk that the change in market interest rates may adversely affect the Company's net interest income. Management continually develops and implements strategies to mitigate this risk. The analysis of the Company's interest rate risk as of December 31, 2016 was presented in the Company's Form 10-K filed with the Securities and Exchange Commission on March 1, 2017. The Company has not experienced any material changes to its interest rate risk position since December 31, 2016. Management does not believe that the Company's primary market risk exposure and management of that exposure in the first six months of 2017 materially changed compared to those in the year ended December 31, 2016.

Item 4. Controls and Procedures

a. Evaluation of disclosure controls and procedures. As of the end of the period covered by this report, an evaluation of the effectiveness of the Company's disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) was performed under the supervision, and with the participation, of the Company's Chief Executive Officer and Chief Financial Officer. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company's disclosure controls and procedures were effective as of the end of the period covered by this report to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act was recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

b. Changes in internal controls over financial reporting. There were no changes in the Company's internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Part II - OTHER INFORMATION

Item 1. Legal Proceedings

Neither the Company nor West Bank is a party, and no property of these entities is subject, to any material pending legal proceedings, other than ordinary routine litigation incidental to West Bank's business. The Company does not know of any proceeding contemplated by a governmental authority against the Company or West Bank.

Item 1A. Risk Factors

Management does not believe there have been any material changes in the risk factors that were disclosed in the Company's Form 10-K filed with the Securities and Exchange Commission on March 1, 2017.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [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, 2016.  In the opinion of management, the accompanying consolidated financial statements of the Company contain all adjustments necessary to fairly present its financial position as of June 30, 2017 and December 31, 2016, net income and comprehensive income for the three and six months ended June 30, 2017 and 2016, and cash flows for the six months ended June 30, 2017 and 2016.  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 consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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 and other than temporary impairment (OTTI) of financial instruments and the allowance for loan losses.

The accompanying unaudited consolidated financial statements include the accounts of the Company, West Bank and West Bank's wholly-owned subsidiary WB Funding Corporation.  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.

Current accounting developments:  In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606): Summary and Amendments that Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs—Contracts with Customers (Subtopic 340-40). The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the Codification. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2017. The guidance does not apply to revenues associated with financial instruments, including loans and investment securities. The Company does not expect the guidance to have a material impact on the Company's consolidated financial statements, as the most significant sources of revenue are excluded from the scope of Topic 606.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The update enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information by updating certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Among other changes, the update requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, and clarifies that entities should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entities' other deferred tax assets. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2017, and is to be applied on a modified retrospective basis. The Company is currently assessing the impact of this guidance, but does not expect the guidance to have a material impact on the Company's consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The guidance in the update supersedes the requirements in ASC Topic 840, Leases. The update will require business entities to recognize lease assets and liabilities for leases with lease terms of more than 12 months on their balance sheet and to disclose key information about leasing arrangements. A lessee would recognize a liability to make lease payments and a right-of-use asset representing its right to use the leased asset for the lease term. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis. The Company currently leases its main location and space for six other branch offices and operational departments under operating leases that will result in recognition of lease assets and lease liabilities on the consolidated balance sheets under the ASU. The amount of assets and liabilities added to the balance sheet are not expected to have a material impact on the Company's consolidated financial statements per preliminary estimates.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718). The update simplifies several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance also allows an entity to make an entity-wide accounting policy election to either estimate expected forfeitures or account for forfeitures as they occur. For public companies, the update was effective for annual periods beginning after December 15, 2016. Portions of the amended guidance were to be applied using a modified retrospective transition method, and others require prospective application. Upon adoption of this update on January 1, 2017, the Company made the accounting policy election to account for forfeitures as they occur. This resulted in no effect on the Company's consolidated financial statements, as prior stock-based compensation expense assumed no expected forfeitures. Also upon adoption, the Company changed the calculation of the assumed proceeds of the treasury stock method on a prospective basis to eliminate deferred taxes from the calculation. The net impact on the income statement is dependent upon the change in the Company's stock price from grant date to vesting date and cannot be predicted with any certainty. The requirement to report the excess tax benefit or shortfall related to settlements of share-based payment awards in earnings as an increase or decrease to tax expense has been applied to settlements occurring on or after January 1, 2017, and the impact of applying that guidance reduced reported income tax expense $244 for the six months ended June 30, 2017.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). The amendments in this update require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net carrying value at the amount expected to be collected on the financial assets. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount of financial assets. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis is determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are recorded as a credit loss expense for these assets. Off-balance-sheet arrangements such as commitments to extend credit, guarantees, and standby letters of credit that are not considered derivatives under ASC 815 and are not unconditionally cancellable are also within the scope of this update. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. For public companies, the update is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this update earlier as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. An entity will apply the amendments in this update on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is currently planning for the implementation of this accounting standard. It is too early to assess the impact that this guidance will have on the Company's consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in this update provide guidance for eight specific cash flow classification issues for which current guidance is unclear or does not exist, thereby reducing diversity in practice. For public companies, the update is effective for annual periods beginning after December 15, 2017, with early adoption permitted. The Company's early adoption of the update as of January 1, 2017, did not have a material impact on the Company's consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20). This update amends the amortization period for certain purchased callable debt securities held at a premium. The update shortens the premium's amortization period to the earliest call date. For public companies, the update is effective for annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis with a cumulative-effect adjustment directly to retained earnings as of the beginning of the adoption period. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company does not expect the guidance to have a material impact on the Company's consolidated financial statements.

Earnings Per Common Share (Notes)

Earnings Per 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 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 calculations of earnings per common share and diluted earnings per common share for the three and six months ended June 30, 2017 and 2016 are presented in the following table.

As of June 30, 2017, the available for sale and held to maturity securities with unrealized losses included 27 state and political subdivision securities, 25 collateralized mortgage obligation securities, four mortgage-backed securities, one trust preferred security and one corporate note. The Company believed the unrealized losses on investments available for sale and held to maturity as of June 30, 2017 were due to market conditions rather than reduced estimated cash flows. 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 as of June 30, 2017.

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 June 30, 2017 and December 31, 2016.

	June 30, 2017			December 31, 2016
Commercial	$	315,098		$	334,014
Real estate:
Construction, land and land development	232,579			205,610
1-4 family residential first mortgages	50,362			47,184
Home equity	15,849			18,057
Commercial	814,755			788,000
Consumer and other loans	8,057			8,355
	1,436,700			1,401,220
Net unamortized fees and costs	(1,321		)	(1,350		)
	$	1,435,379		$	1,399,870

Real estate loans of approximately $680,000 were pledged as security for Federal Home Loan Bank (FHLB) advances as of June 30, 2017 and December 31, 2016.

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 past due 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 a troubled debt restructured (TDR) loan when the Company separately concludes that a borrower is experiencing financial difficulties and a concession is granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden of 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 also be reported as nonaccrual or past due 90 days 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 loans classified as Doubtful, Substandard and Watch according to the Company's classification criteria. These loans involve the anticipated potential for 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.

TDR loans totaled $360 and $426 as of June 30, 2017 and December 31, 2016, respectively, and were included in nonaccrual loans. There were no loan modifications considered to be TDR that occurred during the three and six months ended June 30, 2017 and 2016. The recorded investment in TDR loans that have been modified within the twelve months preceding June 30, 2017 and June 30, 2016, and that have subsequently had a payment default, totaled $0 and $20, respectively. A TDR loan is considered to have a payment default when it is past due 30 days or more.

The following table summarizes the recorded investment in impaired loans by segment, broken down by loans with no related allowance for loan losses and loans with a related allowance and the amount of that allowance as of June 30, 2017 and December 31, 2016.

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's financial condition is satisfactory and stable.  The borrower has satisfactory debt service capacity, and the loan is well secured. The loan is performing as agreed, and the financial characteristics and trends 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 flows 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 the borrower is not able to make scheduled principal and interest payments and any collateral securing the loan declines 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 five 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 of 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.  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 the current economic conditions that may affect the borrower's ability to pay.  Loans are charged-off against the allowance for loan losses when management believes that collectability of the principal is unlikely. 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.

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 the changes in the allowance for loan losses by segment for the three and six months ended June 30, 2017 and 2016.

Long-Term Debt

On May 25, 2017, the Company entered into a credit agreement with a commercial bank and borrowed $25,000. This credit agreement replaced a prior credit agreement with the same commercial bank that had a remaining outstanding principal balance of $3,000. The additional borrowing was used to make a capital injection into the Company's subsidiary, West Bank. Principal and interest under the term note are payable quarterly over five years. The interest rate is variable at 1.95 percent over the 30-day LIBOR rate. The interest rate was 3.03 percent at June 30, 2017. In the case of an event of default, the unaffiliated commercial bank may accelerate the payment of the loan. The loan is secured by 100 percent of the stock of West Bank.

Derivatives

The Company has entered into various forward-starting interest rate swap transactions to effectively convert variable rate FHLB advances and junior subordinated notes to fixed rate debt as of forward-starting dates. The swap transactions were designated as cash flow hedges. Interest rate swaps with a total notional amount of $70,000 were terminated in 2015, subject to termination fees totaling $541. The termination fees are being reclassified from accumulated other comprehensive income to interest expense over the remaining life of the underlying cash flows through June 2020. An interest rate swap with a notional amount of $30,000 became effective in December 2015. Another interest rate swap, with a notional amount of $20,000, has a forward-starting date in September 2018. No amount of ineffectiveness was included in net income for the six months ended June 30, 2017 or 2016, and the Company estimates there will be approximately $426 of cash payments and reclassification from accumulated other comprehensive income to interest expense through the 12 months ended June 30, 2018. 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. As of June 30, 2017 and December 31, 2016, the Company pledged $470 and $470, respectively, of collateral to the counterparty in the form of cash on deposit with a third party. The Company's counterparty was required to pledge $830 and $1,070 at June 30, 2017 and December 31, 2016, respectively.

The table below identifies the balance sheet category and fair values of the Company's derivative instruments designated as cash flow hedges as of June 30, 2017 and December 31, 2016.

Commitments and Contingencies

Financial instruments with off-balance-sheet risk: 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 consisted of the following approximate amounts as of June 30, 2017 and December 31, 2016. 

	June 30, 2017		December 31, 2016
Commitments to extend credit	$	575,955	$	614,681
Standby letters of credit	4,407		5,487
	$	580,362	$	620,168

West Bank previously executed Mortgage Partnership Finance (MPF) Master Commitments (Commitments) with the FHLB of Des Moines to deliver residential 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 residential mortgage loans. At June 30, 2017, 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 $156. The outstanding balance of mortgage loans sold under the MPF Program was $102,986 and $112,084 at June 30, 2017 and December 31, 2016, respectively.

Contractual commitments: The Company has remaining commitments to invest in qualified affordable housing projects totaling $6,447 and $5,768 as of June 30, 2017 and December 31, 2016, respectively.

Contingencies: Neither the Company nor West Bank is a party, and no property of these entities is subject, to any material pending legal proceedings, other than ordinary routine litigation incidental to West Bank's business. The Company does not know of any proceeding contemplated by a governmental authority against the Company or West Bank.

Fair Value Disclosures [Abstract]

Fair Value Disclosures [Text Block]

Fair Value Measurements

Accounting guidance on fair value measurements and disclosuresdefines fair value and establishes a framework for measuring the fair value of assets and liabilities using a hierarchy system.  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 investment 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 six months ended June 30, 2017.

The following is a description of valuation methodologies used for financial assets and liabilities recorded at fair value on a recurring basis.

Investment 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 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, asset-backed securities, state and political subdivision securities, and trust preferred securities. The Company currently holds no investment securities classified as Level 3.

Generally, management obtains the fair value of investment securities at the end of each reporting period via a third-party pricing service. Management reviewed the valuation process used by the third party and believed that process was valid. On a quarterly basis, the Company tests the fair values by selecting a sample of investment securities from each category of securities, obtaining pricing from an independent investment portfolio management firm and comparing the two sets of fair values. Any significant variances are reviewed and investigated. For a sample of securities, prices are further validated by management, with assistance from an independent investment portfolio management 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 the investment securities were properly classified in the fair value hierarchy as of the end of the period covered by this report.

Derivative instruments: The Company's derivative instruments consist of interest rate swaps, which are accounted for as cash flow hedges. The Company's derivative positions are classified within Level 2 of the fair value hierarchy and are 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 derivatives are 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.

The following tables present the balances of financial assets and liabilities measured at fair value on a recurring basis by level as of June 30, 2017 and December 31, 2016.

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).  As of both June 30, 2017 and December 31, 2016, impaired loans for which a fair value adjustment was recorded were recorded at a net value of $0.  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.  The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate.  Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. 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 and may be discounted based on management's opinions concerning market developments or the client's business.

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 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:  The carrying amount approximates fair value.

Investment securities held to maturity: The fair values of these securities, which are all state and political subdivisions, are determined by the same method previously described for investment securities available for sale.

FHLB stock:  The fair value of this restricted stock is estimated at its carrying value and redemption price of $100 per share.

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 values 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 time deposits are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered on time deposits with similar terms.

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, short-term borrowings, variable rate FHLB advances, and variable rate long-term borrowings approximate their fair values.  Fair values of subordinated notes, a fixed rate FHLB advance 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 presents the carrying amounts and approximate fair values of financial assets and liabilities as of June 30, 2017 and December 31, 2016.

Organization, Consolidation and Presentation of Financial Statements [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, 2016.  In the opinion of management, the accompanying consolidated financial statements of the Company contain all adjustments necessary to fairly present its financial position as of June 30, 2017 and December 31, 2016, net income and comprehensive income for the three and six months ended June 30, 2017 and 2016, and cash flows for the six months ended June 30, 2017 and 2016.  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 consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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 and other than temporary impairment (OTTI) of financial instruments 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 and West Bank's wholly-owned subsidiary WB Funding Corporation.  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]

Current accounting developments:  In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606): Summary and Amendments that Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs—Contracts with Customers (Subtopic 340-40). The guidance in this update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the Codification. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2017. The guidance does not apply to revenues associated with financial instruments, including loans and investment securities. The Company does not expect the guidance to have a material impact on the Company's consolidated financial statements, as the most significant sources of revenue are excluded from the scope of Topic 606.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The update enhances the reporting model for financial instruments to provide users of financial statements with more decision-useful information by updating certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Among other changes, the update requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, and clarifies that entities should evaluate the need for a valuation allowance on a deferred tax asset related to available for sale securities in combination with the entities' other deferred tax assets. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2017, and is to be applied on a modified retrospective basis. The Company is currently assessing the impact of this guidance, but does not expect the guidance to have a material impact on the Company's consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The guidance in the update supersedes the requirements in ASC Topic 840, Leases. The update will require business entities to recognize lease assets and liabilities for leases with lease terms of more than 12 months on their balance sheet and to disclose key information about leasing arrangements. A lessee would recognize a liability to make lease payments and a right-of-use asset representing its right to use the leased asset for the lease term. For public companies, this update will be effective for interim and annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis. The Company currently leases its main location and space for six other branch offices and operational departments under operating leases that will result in recognition of lease assets and lease liabilities on the consolidated balance sheets under the ASU. The amount of assets and liabilities added to the balance sheet are not expected to have a material impact on the Company's consolidated financial statements per preliminary estimates.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718). The update simplifies several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance also allows an entity to make an entity-wide accounting policy election to either estimate expected forfeitures or account for forfeitures as they occur. For public companies, the update was effective for annual periods beginning after December 15, 2016. Portions of the amended guidance were to be applied using a modified retrospective transition method, and others require prospective application. Upon adoption of this update on January 1, 2017, the Company made the accounting policy election to account for forfeitures as they occur. This resulted in no effect on the Company's consolidated financial statements, as prior stock-based compensation expense assumed no expected forfeitures. Also upon adoption, the Company changed the calculation of the assumed proceeds of the treasury stock method on a prospective basis to eliminate deferred taxes from the calculation. The net impact on the income statement is dependent upon the change in the Company's stock price from grant date to vesting date and cannot be predicted with any certainty. The requirement to report the excess tax benefit or shortfall related to settlements of share-based payment awards in earnings as an increase or decrease to tax expense has been applied to settlements occurring on or after January 1, 2017, and the impact of applying that guidance reduced reported income tax expense $244 for the six months ended June 30, 2017.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326). The amendments in this update require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial assets to present the net carrying value at the amount expected to be collected on the financial assets. The income statement reflects the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount of financial assets. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. The allowance for credit losses for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination that are measured at amortized cost basis is determined in a similar manner to other financial assets measured at amortized cost basis; however, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Only subsequent changes in the allowance for credit losses are recorded as a credit loss expense for these assets. Off-balance-sheet arrangements such as commitments to extend credit, guarantees, and standby letters of credit that are not considered derivatives under ASC 815 and are not unconditionally cancellable are also within the scope of this update. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. For public companies, the update is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this update earlier as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. An entity will apply the amendments in this update on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company is currently planning for the implementation of this accounting standard. It is too early to assess the impact that this guidance will have on the Company's consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in this update provide guidance for eight specific cash flow classification issues for which current guidance is unclear or does not exist, thereby reducing diversity in practice. For public companies, the update is effective for annual periods beginning after December 15, 2017, with early adoption permitted. The Company's early adoption of the update as of January 1, 2017, did not have a material impact on the Company's consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20). This update amends the amortization period for certain purchased callable debt securities held at a premium. The update shortens the premium's amortization period to the earliest call date. For public companies, the update is effective for annual periods beginning after December 15, 2018, and is to be applied on a modified retrospective basis with a cumulative-effect adjustment directly to retained earnings as of the beginning of the adoption period. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments must be reflected as of the beginning of the fiscal year that includes that interim period. The Company does not expect the guidance to have a material impact on the Company's consolidated financial statements.

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 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.

Loans and Leases Receivable, Origination Fees, Discounts or Premiums, and Direct Costs to Acquire Loans Policy [Policy Text Block]

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.

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 past due 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 a troubled debt restructured (TDR) loan when the Company separately concludes that a borrower is experiencing financial difficulties and a concession is granted that would not otherwise be considered. Concessions may include a restructuring of the loan terms to alleviate the burden of 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 also be reported as nonaccrual or past due 90 days 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 loans classified as Doubtful, Substandard and Watch according to the Company's classification criteria. These loans involve the anticipated potential for 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.  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 the current economic conditions that may affect the borrower's ability to pay.  Loans are charged-off against the allowance for loan losses when management believes that collectability of the principal is unlikely. 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.

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 disclosuresdefines fair value and establishes a framework for measuring the fair value of assets and liabilities using a hierarchy system.  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 investment 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 six months ended June 30, 2017.

The following is a description of valuation methodologies used for financial assets and liabilities recorded at fair value on a recurring basis.

Investment 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 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, asset-backed securities, state and political subdivision securities, and trust preferred securities. The Company currently holds no investment securities classified as Level 3.

Generally, management obtains the fair value of investment securities at the end of each reporting period via a third-party pricing service. Management reviewed the valuation process used by the third party and believed that process was valid. On a quarterly basis, the Company tests the fair values by selecting a sample of investment securities from each category of securities, obtaining pricing from an independent investment portfolio management firm and comparing the two sets of fair values. Any significant variances are reviewed and investigated. For a sample of securities, prices are further validated by management, with assistance from an independent investment portfolio management 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 the investment securities were properly classified in the fair value hierarchy as of the end of the period covered by this report.

Derivative instruments: The Company's derivative instruments consist of interest rate swaps, which are accounted for as cash flow hedges. The Company's derivative positions are classified within Level 2 of the fair value hierarchy and are 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 derivatives are 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.

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 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:  The carrying amount approximates fair value.

Investment securities held to maturity: The fair values of these securities, which are all state and political subdivisions, are determined by the same method previously described for investment securities available for sale.

FHLB stock:  The fair value of this restricted stock is estimated at its carrying value and redemption price of $100 per share.

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 values 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 time deposits are estimated using discounted cash flow analysis, based on observable market interest rates currently being offered on time deposits with similar terms.

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, short-term borrowings, variable rate FHLB advances, and variable rate long-term borrowings approximate their fair values.  Fair values of subordinated notes, a fixed rate FHLB advance 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.

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.
