	Principles of Consolidation and Presentation
	MidWestOne Financial Group, Inc. (the “Company,” which is also referred to herein as “we,” “our” or “us”) is an Iowa corporation incorporated in 1983, a bank holding company under the Bank Holding Company Act of 1956 and a financial holding company under the Gramm-Leach-Bliley Act of 1999. Our principal executive offices are located at 102 South Clinton Street, Iowa City, Iowa 52240.
	The Company owns 100% of the outstanding common stock of MidWestOne Bank, an Iowa state non-member bank chartered in 1934 with its main office in Iowa City, Iowa (the “Bank”), and 100% of the common stock of MidWestOne Insurance Services, Inc., Oskaloosa, Iowa. We operate primarily through our bank subsidiary, MidWestOne Bank, and MidWestOne Insurance Services, Inc., our wholly-owned subsidiary that operates an insurance agency business through six offices located in central and east-central Iowa.
	The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all the information and notes necessary for complete financial statements in conformity with U.S. Generally Accepted Accounting Principles ("GAAP"). The information in this Quarterly Report on Form 10-Q is written with the presumption that the users of the interim financial statements have read or have access to the most recent Annual Report on Form 10-K of the Company, which contains the latest audited financial statements and notes thereto, together with Management's Discussion and Analysis of Financial Condition and Results of Operations as of December 31, 2013 and for the year then ended. Management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, the accompanying consolidated financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to present fairly the financial position as of June 30, 2014, and the results of operations and cash flows for the three and six months ended June 30, 2014 and 2013. All significant intercompany accounts and transactions have been eliminated in consolidation.
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect: (1) the reported amounts of assets and liabilities, (2) the disclosure of contingent assets and liabilities at the date of the financial statements, and (3) the reported amounts of revenues and expenses during the reporting period. These estimates are based on information available to management at the time the estimates are made. Actual results could differ from those estimates. The results for the three and six months ended June 30, 2014 may not be indicative of results for the year ending December 31, 2014, or for any other period.
	All significant accounting policies followed in the preparation of the quarterly financial statements are disclosed in the Annual Report on Form 10-K for the year ended December 31, 2013. In the consolidated statements of cash flows, cash and cash equivalents include cash and due from banks and interest-bearing deposits in banks.

	Shareholders' Equity
	Preferred Stock: The number of authorized shares of preferred stock for the Company is 500,000. As of June 30, 2014, none were issued or outstanding.
	Common Stock: As of June 30, 2014, the number of authorized shares of common stock for the Company was 15,000,000. As of June 30, 2014, 8,396,191 shares were outstanding.
	On January 15, 2013, the Company's board of directors announced the renewal of the Company's share repurchase program, extending the expiration of the program to December 31, 2014 and increasing the remaining amount of authorized repurchases under the program to $5.0 million from the approximately $2.4 million of authorized repurchases that had previously remained. As of June 30, 2014 the remaining amount available for share repurchases under the program was $1.3 million.
	On July 17, 2014, the board of directors of the Company approved a new share repurchase program, allowing for the repurchase of up to $5.0 million of stock through December 31, 2016. The new repurchase program replaces the Company's prior repurchase program. Pursuant to the program, the Company may continue to repurchase shares from time to time in the open market, and the method, timing and amounts of repurchase will be solely in the discretion of the Company's management. The repurchase program does not require the Company to acquire a specific number of shares. Therefore, the amount of shares repurchased pursuant to the program will depend on several factors, including market conditions, capital and liquidity requirements, and alternative uses for cash available.

	Earnings per Common Share
	Basic per-share amounts are computed by dividing net income (the numerator) by the weighted-average number of common shares outstanding (the denominator). Diluted per share amounts assume issuance of all common stock issuable upon conversion or exercise of other securities, unless the effect is to reduce the loss or increase the income per common share from continuing operations.
	The following table presents the computation of earnings per common share for the respective periods:

The Company's assessment of other-than-temporary impairment ("OTTI") is based on its reasonable judgment of the specific facts and circumstances impacting each individual security at the time such assessments are made. The Company reviews and considers factual information, including expected cash flows, the structure of the security, the creditworthiness of the issuer, the type of underlying assets and the current and anticipated market conditions.
At June 30, 2014 and December 31, 2013, the Company's mortgage-backed securities portfolio consisted of securities predominantly backed by one- to four- family mortgage loans and underwritten to the standards of and guaranteed by the following government-sponsored agencies: the Federal Home Loan Mortgage Corporation (FHLMC), the Federal National Mortgage Association (FNMA), and the Government National Mortgage Association (GNMA). The receipt of principal, at par, and interest on mortgage-backed securities is guaranteed by the respective government-sponsored agency guarantor, such that the Company believes that its mortgage-backed securities do not expose the Company to credit-related losses.
At June 30, 2014, approximately 61% of the municipal bonds held by the Company were Iowa based. The Company does not intend to sell these municipal obligations, and it is not more likely than not that the Company will be required to sell them before the recovery of its cost. Due to the issuers' continued satisfaction of their obligations under the securities in accordance with their contractual terms and the expectation that they will continue to do so, management's intent and ability to hold these securities for a period of time sufficient to allow for any anticipated recovery in fair value, as well as the evaluation of the fundamentals of the issuers' financial condition and other objective evidence, the Company believes that the municipal obligations identified in the tables above were temporarily depressed as of June 30, 2014 and December 31, 2013.
At December 31, 2013, the Company owned five collateralized debt obligations ("CDOs") backed by pools of trust preferred securities with an original cost basis of $8.8 million. The amortized cost of these securities as of December 31, 2013 totaled $2.1 million, after OTTI charges had been recognized. During the quarter ended March 31, 2014, the Company sold these investment securities at a net gain of $0.8 million.
As of June 30, 2014, the Company also owned $2.1 million of equity securities in banks and financial service-related companies, and $1.0 million of mutual funds invested in debt securities and other debt instruments that will cause units of the fund to be deemed to be qualified under the Community Reinvestment Act. Equity securities are considered to have OTTI whenever they have been in a loss position, compared to current book value, for twelve consecutive months, and the Company does not expect them to recover to their original cost basis. For the six months ended June 30, 2014 and the full year of 2013, no impairment charges were recorded, as the affected equity securities were not deemed impaired due to stabilized market prices in relation to the Company's original purchase price.
The following table provides a roll forward of credit losses on fixed maturity securities recognized in net income:


		For the Three Months Ended June 30,								For the Six Months Ended June 30,
		2014				2013				2014				2013

	Securities with other than temporary impairment, due to sale	—				—				(6,639		)		—

	Ending balance	$	—			$	7,379			$	—			$	7,379

It is reasonably possible that the fair values of the Company's investment securities could decline in the future if the overall economy or the financial condition of the issuers deteriorate or the liquidity of certain securities remains depressed. As a result, there is a risk that additional OTTI may be recognized in the future and any such amounts could be material to the Company's consolidated statements of operations.

The contractual maturity distribution of investment debt securities at June 30, 2014, is summarized as follows:


		Available For Sale								Held to Maturity
		Amortized				Fair Value				Amortized				Fair Value
		Cost								Cost

Mortgage-backed securities and collateralized mortgage obligations are collateralized by mortgage loans guaranteed by U.S. government agencies. Experience has indicated that principal payments will be collected sooner than scheduled because of prepayments. Therefore, these securities are not scheduled in the maturity categories indicated above. Equity securities available for sale with an amortized cost of $2.7 million and a fair value of $3.1 million are also excluded from this table.
Other investment securities include investments in Federal Home Loan Bank (“FHLB”) stock. The carrying value of the FHLB stock at June 30, 2014 was $9.0 million and at December 31, 2013 was $9.2 million, which is included in the Other Assets line of the consolidated balance sheets. This security is not readily marketable and ownership of FHLB stock is a requirement for membership in the FHLB-Des Moines. The amount of FHLB stock the Bank is required to hold is directly related to the amount of FHLB advances borrowed. Because there are no available market values, this security is carried at cost and evaluated for potential impairment each quarter. Redemption of this investment is at the option of the FHLB.
Realized gains and losses on sales are determined on the basis of specific identification of investments based on the trade date. Realized gains on investments for the three and six months ended June 30, 2014 and 2013 are as follows:

Loan Portfolio Segment Risk Characteristics
Agricultural - Agricultural loans, most of which are secured by crops, livestock, and machinery, are provided to finance capital improvements and farm operations as well as acquisitions of livestock and machinery. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business. The ability of the borrower to repay may be affected by many factors outside of the borrower's control including adverse weather conditions, loss of livestock due to disease or other factors, declines in market prices for agricultural products and the impact of government regulations. The ultimate repayment of agricultural loans is dependent upon the profitable operation or management of the agricultural entity.

Commercial and Industrial - Commercial and industrial loans are primarily made based on the reported cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The collateral support provided by the borrower for most of these loans and the probability of repayment are based on the liquidation of the pledged collateral and enforcement of a personal guarantee, if any exists. The primary repayment risks of commercial and industrial loans are that the cash flows of the borrower may be unpredictable, and the collateral securing these loans may fluctuate in value. The size of the loans the Company can offer to commercial customers is less than the size of the loans that competitors with larger lending limits can offer. This may limit the Company's ability to establish relationships with the largest businesses in the areas in which the Company operates. As a result, the Company may assume greater lending risks than financial institutions that have a lesser concentration of such loans and tend to make loans to larger businesses. Collateral for these loans generally includes accounts receivable, inventory, equipment and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to appraise and may fluctuate in value based on the success of the business. In addition, if the U.S. economy does not continue to improve, this could harm or continue to harm the businesses of the Company's commercial and industrial customers and reduce the value of the collateral securing these loans.

Commercial Real Estate - The Company offers mortgage loans to commercial and agricultural customers for the acquisition of real estate used in their businesses, such as offices, warehouses and production facilities, and to real estate investors for the acquisition of apartment buildings, retail centers, office buildings and other commercial buildings. The market value of real estate securing commercial real estate loans can fluctuate significantly in a short period of time as a result of market conditions in the geographic area in which the real estate is located. Adverse developments affecting real estate values in one or more of the Company's markets could increase the credit risk associated with its loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts than non-real estate loans, and the repayment of the loans generally is dependent, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service. Economic events or governmental regulations outside of the Company's control or that of the borrower could negatively impact the future cash flow and market values of the affected properties.

Residential Real Estate - The Company generally retains short-term residential mortgage loans that are originated for its own portfolio but sells most long-term loans to other parties while retaining servicing rights on the majority of those loans. The market value of real estate securing residential real estate loans can fluctuate as a result of market conditions in the geographic area in which the real estate is located. Adverse developments affecting real estate values in one or more of the Company's markets could increase the credit risk associated with its loan portfolio. Additionally, real estate lending typically involves higher loan principal amounts than non-real estate loans, and the repayment of the loans generally is dependent, in large part, on the borrower's continuing financial stability, and is therefore more likely to be affected by adverse personal circumstances.

Consumer - Consumer loans typically have shorter terms, lower balances, higher yields and higher risks of default than real estate related loans. Consumer loan collections are dependent on the borrower's continuing financial stability, and are therefore more likely to be affected by adverse personal circumstances. Collateral for these loans generally includes automobiles, boats, recreational vehicles, mobile homes, and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to recover and may fluctuate in value based on condition. In addition, a decline in the United States economy could result in reduced employment, impacting the ability of customers to repay their obligations.

Loans acquired with deteriorated credit quality (loan pool participations) - The underlying loans in the loan pool participations include both fixed-rate and variable-rate instruments. No amounts for interest due are reflected in the carrying value of the loan pool participations. Based on historical experience, the average period of collectibility for loans underlying loan pool participations, many of which have exceeded contractual maturity dates, is approximately three to five years. Loan pool balances are affected by the payment and refinancing activities of the borrowers resulting in pay-offs of the underlying loans and reduction in the balances. Collections from the individual borrowers are managed by the loan pool servicer and are affected by the borrower's financial ability and willingness to pay, foreclosure and legal action, collateral value, and the economy in general.
Charge-off Policy
The Company requires a loan to be charged-off as soon as it becomes apparent that some loss will be incurred, or when its collectability is sufficiently questionable that it no longer is considered a bankable asset. The primary considerations when determining if and how much of a loan should be charged-off are as follows: (1) the potential for future cash flows; (2) the value of any collateral; and (3) the strength of any co-makers or guarantors.

When it is determined that a loan requires a partial or full charge-off, a request for approval of a charge-off is submitted to the Bank's President, Executive Vice President and Chief Credit Officer, and the Senior Regional Loan officer. The Bank's board of directors formally approves all loan charge-offs. Once a loan is charged-off, it cannot be restructured and returned to the Bank's books.
The Allowance for Loan and Lease Losses - Bank Loans
The Company requires the maintenance of an adequate allowance for loan and lease losses (“ALLL”) in order to cover estimated probable losses without eroding the Company's capital base. Calculations are done at each quarter end, or more frequently if warranted, to analyze the collectability of loans and to ensure the adequacy of the allowance. In line with Federal Deposit Insurance Corporation (the "FDIC") directives, the ALLL calculation does not include consideration of loans held for sale or off-balance-sheet credit exposures (such as unfunded letters of credit). Determining the appropriate level for the ALLL relies on the informed judgment of management, and as such, is subject to inaccuracy. Given the inherently imprecise nature of calculating the necessary ALLL, the Company's policy permits an "unallocated" allowance between 15% above and 5% below the “indicated reserve.” These unallocated amounts are due to those overall factors impacting the ALLL that are not captured in detailed loan category calculations.

The Company identifies loans to be reviewed and evaluated individually for impairment based on current information and events and the probability that the borrower will be unable to repay all amounts due according to the contractual terms of the loan agreement. Specific areas of consideration include: size of credit exposure, risk rating, delinquency, nonaccrual status, and loan classification.

The level of individual impairment is measured using one of the following methods: (1) the fair value of the collateral less costs to sell; (2) the present value of expected future cash flows, discounted at the loan's effective interest rate; or (3) the loan's observable market price. Loans that are deemed fully collateralized or have been charged down to a level corresponding with any of the three measurements require no assignment of reserves from the ALLL.

All loans deemed troubled debt restructure or “TDR” are considered impaired. A loan is considered a TDR when the Bank, for economic or legal reasons related to a borrower's financial difficulties, grants a concession to the borrower that the Bank would not otherwise consider. All of the following factors are potential indicators that the Bank has granted a concession (one or multiple items may be present):


•	The borrower receives a reduction of the stated interest rate for the remaining original life of the debt.

•	The borrower receives an extension of the maturity date or dates at a stated interest rate lower that the current market interest rate for new debt with similar risk characteristics.

•	The borrower receives a reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement.

•	The borrower receives a deferral of required payments (principal and/or interest).

•	The borrower receives a reduction of the accrued interest.

Loans Reviewed Collectively for Impairment
All loans not evaluated individually for impairment are grouped together by type (i.e. commercial, agricultural, consumer, etc.) and further segmented within each subset by risk classification (i.e. pass, special mention, and substandard). Homogeneous loans past due 60-89 days and 90 days and over are classified special mention and substandard, respectively, for allocation purposes.

The Company's historical loss experience for each loan type is calculated using the fiscal quarter-end data for the most recent 20 quarters as a starting point for estimating losses. In addition, other prevailing qualitative or environmental factors likely to cause probable losses to vary from historical data are incorporated in the form of adjustments to increase or decrease the loss rate applied to each group. These adjustments are documented and fully explain how the current information, events, circumstances, and conditions impact the historical loss measurement assumptions.

Although not a comprehensive list, the following are considered key factors and are evaluated with each calculation of the ALLL to determine if adjustments to historical loss rates are warranted:


•	Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses.

•	Changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments.

•	Changes in the nature and volume of the portfolio and in the terms of loans.

•	Changes in the experience, ability and depth of lending management and other relevant staff.

•	Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans.

•	Changes in the quality of our loan review system.

•	Changes in the value of underlying collateral for collateral-dependent loans.

•	The existence and effect of any concentrations of credit, and changes in the level of such concentrations.

•	The effect of other external factors, such as competition and legal and regulatory requirements, on the level of estimated credit losses in the Bank's existing portfolio.
The items listed above are used to determine the pass percentage for loans evaluated collectively and, as such, are applied to the loans risk rated pass. Due to the inherent risks associated with special mention risk rated loans (i.e. early stages of financial deterioration, technical exceptions, etc.), this subset is reserved at two times the pass allocation factor to reflect this increased risk exposure. In addition, non-impaired loans classified as substandard loans carry greater risk than special mention loans, and as such, this subset is reserved at six times the pass allocation. Further, non-impaired loans less than $0.2 million that are past due 60 - 89 days or 90 days and over, are respectively classified as special mention or substandard. They are given an increased loan loss allocation of 25% or 50%, respectively, above the five year historical loss rate of the specific loan type.
The Allowance for Loan and Lease Losses - Loan Pool Participations
The Company requires that the loan pool participation ALLL will be at least sufficient to cover the next quarter's estimated charge-offs as presented by the servicer. Currently, charge-offs are netted against the income the Company receives, thus the balance in the loan pool participation reserve is not affected and remains stable. In essence, a provision for loan losses is made that is equal to the quarterly charge-offs, which is deducted from income received from the loan pool participations. By maintaining a sufficient reserve to cover the next quarter's charge-offs, the Company will have sufficient reserves in place should no income be collected from the loan pool participations during the quarter. In the event the estimated charge-offs provided by the servicer are greater than the loan pool participation ALLL, an additional provision is made to cover the difference between the current ALLL and the estimated charge-offs provided by the servicer.

Loans Reviewed Individually for Impairment
The loan servicer reviews the portfolio quarterly on a loan-by-loan basis, and loans that are deemed to be impaired are charged-down to their estimated value. All loans that are to be charged-down are reserved against in the ALLL adequacy calculation. Loans that continue to have an investment basis that have been charged-down are monitored, and if additional impairment is noted, the reserve requirement is increased on the individual loan.

Loans Reviewed Collectively for Impairment
The Company utilizes the annualized average of portfolio loan (not loan pool participations) historical loss per risk category over a two-year period of time. Supporting documentation for the technique used to develop the historical loss rate for each group of loans is required to be maintained. It is management's assessment that the two-year rate is most reflective of the probable credit losses in the current loan pool portfolio.

Special Mention/Watch - A special mention/watch asset has potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company's credit position at some future date. Special mention/watch assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.
Substandard - Substandard loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
Doubtful - Loans classified doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable.
Loss - Loans classified loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be effected in the future.

Non-accrual and Delinquent Loans
Loans are placed on non-accrual when (1) payment in full of principal and interest is no longer expected or (2) principal or interest has been in default for 90 days or more (unless the loan is both well secured with marketable collateral and in the process of collection). All loans rated doubtful or worse, and certain loans rated substandard, are placed on non-accrual.
A non-accrual asset may be restored to an accrual status when (1) all past due principal and interest has been paid (excluding renewals and modifications that involve the capitalizing of interest) or (2) the loan becomes well secured with marketable collateral and is in the process of collection. An established track record of performance is also considered when determining accrual status.
Delinquency status of a loan is determined by the number of days that have elapsed past the loan's payment due date, using the following classification groupings: 30-59 days, 60-89 days and 90 days or more. Loans shown in the 30-59 days and 60-89 days columns in the table above reflect contractual delinquency status of loans not considered nonperforming due to classification as a TDR or being placed on non-accrual.
The following table sets forth the composition of the Company's recorded investment in loans on nonaccrual status as of June 30, 2014 and December 31, 2013:

As of June 30, 2014, the Company had no commitments to lend additional funds to any borrowers who have had a TDR.
Loan Pool Participations
ASC Topic 310 addresses accounting for differences between contractual cash flows and cash flows expected to be collected from an investor's initial investment in loans or debt securities acquired in a transfer if those differences are attributable, at least in part, to credit quality. The loans underlying the loan pool participations were evaluated individually when purchased for application of ASC Topic 310, utilizing various criteria including: past-due status, late payments, legal status of the loan (not in foreclosure, judgment against the borrower, or referred to legal counsel), frequency of payments made, collateral adequacy and the borrower's financial condition. If all the criteria were met, the individual loan utilized the accounting treatment required by ASC Topic 310 with the accretable yield difference between the expected cash flows and the purchased basis accreted into income on the level yield basis over the anticipated life of the loan. If any of the six criteria were not met at the time of purchase, the loan was accounted for on the cash basis of accounting.
The loan servicer reviews the portfolio quarterly on a loan-by-loan basis, and loans that are deemed to be impaired are charged down to their estimated value. As of June 30, 2014, approximately 72% of the loans were contractually current or less than 90 days past due, while 28% were contractually past due 90 days or more. Many of the loans were acquired in a contractually past due status, which was reflected in the discounted purchase price of the loans. Performance status is monitored on a monthly basis. The 28% of loans contractually past due includes loans in litigation and foreclosed property.

	Fair Value Measurements
	Fair value is the price that would be received in selling an asset or paid in transferring a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.

	GAAP requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, GAAP establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

	•	Level 1 Inputs – Unadjusted quoted prices for identical assets or liabilities in active markets that the reporting entity has the ability to access at the measurement date.

	•	Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

	•	Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
	It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. The Company is required to use observable inputs, to the extent available, in the fair value estimation process unless that data results from forced liquidations or distressed sales. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.
	Valuation methods for instruments measured at fair value on a recurring basis.
	Securities Available for Sale - The Company’s investment securities classified as available for sale include: debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies, debt securities issued by state and political subdivisions, mortgage-backed securities, collateralized mortgage obligations, corporate debt securities, and equity securities. Quoted exchange prices are available for equity securities, which are classified as Level 1. The Company utilizes an independent pricing service to obtain the fair value of debt securities. On a quarterly basis, the Company selects a sample of 30 securities from its primary pricing service and compares them to a secondary independent pricing service to validate value. In addition, the Company periodically reviews the pricing methodology utilized by the primary independent service for reasonableness. Debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies and mortgage-backed obligations are priced utilizing industry-standard models that consider various assumptions, including time value, yield curves, volatility factors, prepayment speeds, default rates, loss severity, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace, can be derived from observable data, or are supported by observable levels at which transactions are executed in the marketplace and are classified as Level 2. Municipal securities are valued using a type of matrix, or grid, pricing in which securities are benchmarked against the treasury rate based on credit rating. These model and matrix measurements are classified as Level 2 in the fair value hierarchy. On an annual basis, a group of selected municipal securities are priced by a securities dealer and that price is used to verify the primary independent service’s valuation.
	The Company classified its pooled trust preferred CDOs as Level 3 until such securities were sold in the first quarter of 2014. The portfolio consisted of five investments in CDOs backed by pools of trust preferred securities issued by financial institutions and insurance companies. The Company had determined that the observable market data associated with these assets did not represent orderly transactions and reflected forced liquidations or distressed sales. Based on the lack of observable market data, the Company estimated fair value based on the observable data available and reasonable unobservable market data. The Company estimated fair value based on a discounted cash flow model which used appropriately adjusted discount rates reflecting credit and liquidity risks.
	Mortgage Servicing Rights - The Company recognizes the rights to service mortgage loans for others on residential real estate loans internally originated and then sold. Mortgage servicing rights are recorded at fair value based on assumptions through a third-party valuation service. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Because many of these inputs are unobservable, the valuations are classified as Level 3.
	The following table summarizes assets measured at fair value on a recurring basis as of June 30, 2014 and December 31, 2013. There were no liabilities subject to fair value measurement as of these dates. The assets are segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value:

The following table presents the amount of gains and losses included in earnings and other comprehensive income for the six months ended June 30, 2014 and 2013 that are attributable to the change in unrealized gains and losses relating to those assets still held, and the line item in the consolidated financial statements in which they are included:

	Change in unrealized gains (losses) for the period included in other comprehensive income		794				—				31				—

* Gains on collateralized debt obligations are included in gain on sale or call of available for sale securities, while gains on mortgage servicing rights are included in mortgage origination and loan servicing fees, both in the consolidated statements of operations.
Changes in the fair value of available for sale securities are included in other comprehensive income to the extent the changes are not considered OTTI. OTTI tests are performed on a quarterly basis and any decline in the fair value of an individual security below its cost that is deemed to be other-than-temporary results in a write-down that is reflected directly in the Company's consolidated statements of operations.
Valuation methods for instruments measured at fair value on a nonrecurring basis
Collateral Dependent Impaired Loans - From time to time, a loan is considered impaired and an allowance for credit losses is established. The specific reserves for collateral dependent impaired loans are based on the fair value of the collateral less estimated costs to sell. The fair value of collateral is determined based on appraisals. In some cases, adjustments are made to the appraised values due to various factors, including age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in the collateral. Because many of these inputs are unobservable, the valuations are classified as Level 3.
Other Real Estate Owned ("OREO") - OREO represents property acquired through foreclosures and settlements of loans. Property acquired is carried at the lower of the carrying amount of the loan at the time of acquisition, or the estimated fair value of the property, less disposal costs. The Company considers third party appraisals as well as independent fair value assessments from real estate brokers or persons involved in selling OREO in determining the fair value of particular properties. Accordingly, the valuation of OREO is subject to significant external and internal judgment. The Company also periodically reviews OREO to determine whether the property continues to be carried at the lower of its recorded book value or fair value of the property, less disposal costs. Because many of these inputs are unobservable, the valuations are classified as Level 3.
The following table discloses the Company's estimated fair value amounts of its assets recorded at fair value on a nonrecurring basis. It is management's belief that the fair values presented below are reasonable based on the valuation techniques and data available to the Company as of June 30, 2014 and December 31, 2013, as more fully described above.

The following presents the carrying amount and estimated fair value of the financial instruments held by the Company at June 30, 2014 and December 31, 2013. The information presented is subject to change over time based on a variety of factors. The operations of the Company are managed on a going concern basis and not a liquidation basis. As a result, the ultimate value realized from the financial instruments presented could be substantially different when actually recognized over time through the normal course of operations. Additionally, a substantial portion of the Company's inherent value is the Bank's capitalization and franchise value. Neither of these components has been given consideration in the presentation of fair values below.

•	Cash and cash equivalents, federal funds purchased, securities sold under repurchase agreements, and accrued interest are instruments with carrying values that approximate fair value.

•	Investment securities available for sale are measured at fair value on a recurring basis. Held to maturity securities are carried at amortized cost. Fair value is based upon quoted prices, if available. If a quoted price is not available, the fair value is obtained from benchmarking the security against similar securities by using a third-party pricing service.

•	Loans held for sale are carried at the lower of cost or fair value, with fair value being based on recent observable loan sales. The portfolio has historically consisted primarily of residential real estate loans.

•	For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for other loans are determined using estimated future cash flows, discounted at the interest rates currently being offered for loans with similar terms to borrowers with similar credit quality. The Company does record nonrecurring fair value adjustments to loans to reflect (1) partial write-downs and allowances that are based on the observable market price or appraised value of the collateral or (2) the full charge-off of the loan carrying value.

•	Loan pool participation carrying values represent the discounted price paid by us to acquire our participation interests in the various loan pool participations purchased, which approximates fair value.

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

•	Deposit liabilities are carried at historical cost. The fair value of demand deposits, savings accounts and certain money market account deposits is the amount payable on demand at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. If the fair value of the fixed maturity certificates of deposit is calculated at less than the carrying amount, the carrying value of these deposits is reported as the fair value.

•	FHLB borrowings and long-term debt are recorded at historical cost. The fair value of these items is estimated using discounted cash flow analysis, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements.
The following presents the valuation technique(s), observable inputs, and quantitative information about the unobservable inputs used for fair value measurements of the financial instruments held by the Company at June 30, 2014, categorized within Level 3 of the fair value hierarchy:

* Not Meaningful. Third party appraisals are obtained as to the value of the underlying asset, but disclosure of this information would not provide meaningful information, as the range will vary widely from loan to loan. Types of discounts considered include age of the appraisal, local market conditions, current condition of the property, and estimated sales costs. These discounts will also vary from loan to loan, thus providing a range would not be meaningful.
Changes in assumptions or estimation methodologies may have a material effect on these estimated fair values.

	Variable Interest Entities
	Loan Pool Participations
	The Company has invested in certain participation certificates of loan pools which are purchased, held and serviced by a third-party independent servicing corporation. The Company's portfolio holds approximately 95% of the participation interests in the pools of loans owned and serviced by States Resources Corporation (“SRC”), a third-party loan servicing organization located in Omaha, Nebraska, in which the Company participates. SRC's owner holds the remaining interest. The Company does not have any ownership interest in or exert any control over SRC, and thus it is not included in the consolidated financial statements.
	These pools of loans were purchased from large nonaffiliated banking organizations and from the FDIC acting as receiver of failed banks and savings associations. As loan pools were put out for bid (generally in a sealed bid auction), SRC's due diligence teams evaluated the loans and determined their interest in bidding on the pool. After the due diligence, the Company's management reviewed the status and decided if it wished to continue in the process. If the decision to consider a bid was made, SRC conducted additional analysis to determine the appropriate bid price. This analysis involved discounting loan cash flows with adjustments made for expected losses, changes in collateral values as well as targeted rates of return. A cost or investment basis was assigned to each individual loan on a cents-per-dollar (discounted price) basis based on SRC's assessment of the recovery potential of each loan.
	Once a bid was awarded to SRC, the Company assumed the risk of profit or loss but on a non-recourse basis so the risk is limited to its initial investment. The extent of the risk is also dependent upon: the debtor or guarantor's financial condition, the possibility that a debtor or guarantor may file for bankruptcy protection, SRC's ability to locate any collateral and obtain possession, the value of such collateral, and the length of time it takes to realize the recovery either through collection procedures, legal process, or resale of the loans after a restructure.
	Loan pool participations are shown on the Company's consolidated balance sheets as a separate asset category. The original carrying value or investment basis of loan pool participations is the discounted price paid by the Company to acquire its interests, which, as noted, is less than the face amount of the underlying loans. The Company's investment basis is reduced as SRC recovers principal on the loans and remits its share to the Company or as loan balances are written off as uncollectible.

Description of New Accounting Pronouncements Not yet Adopted [Text Block]	'
	Effect of New Financial Accounting Standards
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The objective of this update is to eliminate the diversity in practice on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. For public entities, the amendments became effective for fiscal years, and interim periods within those years, beginning after December 15, 2013, with early adoption permitted. The adoption of this amendment did not have a material effect on the Company’s consolidated financial statements.
	In January 2014, the FASB issued Accounting Standards Update No. 2014-01, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects. The objective of this update is to provide guidance on accounting for investments by a reporting entity in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. The low-income housing tax credit program is designed to encourage private capital investment in the construction and rehabilitation of low-income housing. This program is an indirect tax subsidy that allows investors in a flow-through limited liability entity, such as limited partnerships or limited liability companies that manage or invest in qualified affordable housing projects, to receive the benefits of the tax credits allocated to the entity that owns the qualified affordable housing project. The tax credits are allowable on the tax return each year over a 10-year period as a result of a sufficient number of units being rented to qualifying tenants and are subject to restrictions on gross rentals paid by those tenants. Those credits are subject to recapture over a 15-year period starting with the first year tax credits are earned. The amendments in this update permit reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. For public entities, the amendments are to be applied retrospectively to all annual periods and interim reporting periods presented within those annual periods, beginning after December 15, 2014. The adoption of this amendment is not expected to have a material effect on the Company’s consolidated financial statements.
	In January 2014, the FASB issued Accounting Standards Update No. 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. The objective of this update is to reduce diversity by clarifying when an in-substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. For public entities, the amendments are effective for reporting periods beginning after December 31, 2014, with early adoption permitted. The adoption of this amendment is not expected to have a material effect on the Company’s consolidated financial statements.

	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contract with Customers (Topic 606). The guidance in this update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (for example, insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following five steps: 1) identify the contracts(s) with the customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations in the contract; and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer. For a public entity, the amendments in this update are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Company is still evaluating the effect of this amendment on the Company’s consolidated financial statements.

	In June 2014, the FASB issued Accounting Standards Update No. 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The guidance in this update changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. It also requires enhanced disclosures about repurchase agreements and other similar transactions. The accounting changes in this update are effective for public companies for the first interim or annual period beginning after December 15, 2014. In addition, for public companies, the disclosure for certain transactions accounted for as a sale is effective for the first interim or annual period beginning on or after December 15, 2014, and the disclosure for transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early application is not permitted. The adoption of this amendment is not expected to have a material effect on the Company’s consolidated financial statements.

	On July 17, 2014, the board of directors of the Company declared a cash dividend of $0.145 per share payable on September 15, 2014 to shareholders of record as of the close of business on September 1, 2014.
	Also on July 17, 2014, the board of directors of the Company approved a new share repurchase program, allowing for the repurchase of up to $5.0 million of stock through December 31, 2016. The new repurchase program replaces the Company's prior repurchase program, pursuant to which the Company had repurchased approximately $3.7 million of common stock since January 1, 2013. Pursuant to the program, the Company may continue to repurchase shares from time to time in the open market, and the method, timing and amounts of repurchase will be solely in the discretion of the Company's management. The repurchase program does not require the Company to acquire a specific number of shares. Therefore, the amount of shares repurchased pursuant to the program will depend on several factors, including market conditions, capital and liquidity requirements, and alternative uses for cash available.

Accounting Policies [Abstract]	'
Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	'
	All loans deemed troubled debt restructure or “TDR” are considered impaired. A loan is considered a TDR when the Bank, for economic or legal reasons related to a borrower's financial difficulties, grants a concession to the borrower that the Bank would not otherwise consider. All of the following factors are potential indicators that the Bank has granted a concession (one or multiple items may be present):


	•	The borrower receives a reduction of the stated interest rate for the remaining original life of the debt.

	•	The borrower receives an extension of the maturity date or dates at a stated interest rate lower that the current market interest rate for new debt with similar risk characteristics.

	•	The borrower receives a reduction of the face amount or maturity amount of the debt as stated in the instrument or other agreement.

	•	The borrower receives a deferral of required payments (principal and/or interest).

	•	The borrower receives a reduction of the accrued interest.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]	'
	The Allowance for Loan and Lease Losses - Bank Loans
	The Company requires the maintenance of an adequate allowance for loan and lease losses (“ALLL”) in order to cover estimated probable losses without eroding the Company's capital base. Calculations are done at each quarter end, or more frequently if warranted, to analyze the collectability of loans and to ensure the adequacy of the allowance. In line with Federal Deposit Insurance Corporation (the "FDIC") directives, the ALLL calculation does not include consideration of loans held for sale or off-balance-sheet credit exposures (such as unfunded letters of credit). Determining the appropriate level for the ALLL relies on the informed judgment of management, and as such, is subject to inaccuracy. Given the inherently imprecise nature of calculating the necessary ALLL, the Company's policy permits an "unallocated" allowance between 15% above and 5% below the “indicated reserve.” These unallocated amounts are due to those overall factors impacting the ALLL that are not captured in detailed loan category calculations.
Loans and Leases Receivable, Past Due Status, Policy [Policy Text Block]	'
	Non-accrual and Delinquent Loans
	Loans are placed on non-accrual when (1) payment in full of principal and interest is no longer expected or (2) principal or interest has been in default for 90 days or more (unless the loan is both well secured with marketable collateral and in the process of collection). All loans rated doubtful or worse, and certain loans rated substandard, are placed on non-accrual.
	A non-accrual asset may be restored to an accrual status when (1) all past due principal and interest has been paid (excluding renewals and modifications that involve the capitalizing of interest) or (2) the loan becomes well secured with marketable collateral and is in the process of collection. An established track record of performance is also considered when determining accrual status.
	Delinquency status of a loan is determined by the number of days that have elapsed past the loan's payment due date, using the following classification groupings: 30-59 days, 60-89 days and 90 days or more. Loans shown in the 30-59 days and 60-89 days columns in the table above reflect contractual delinquency status of loans not considered nonperforming due to classification as a TDR or being placed on non-accrual.
Loan Pool Participations, Policy [Policy Text Block]	'
	Loan Pool Participations
	ASC Topic 310 addresses accounting for differences between contractual cash flows and cash flows expected to be collected from an investor's initial investment in loans or debt securities acquired in a transfer if those differences are attributable, at least in part, to credit quality. The loans underlying the loan pool participations were evaluated individually when purchased for application of ASC Topic 310, utilizing various criteria including: past-due status, late payments, legal status of the loan (not in foreclosure, judgment against the borrower, or referred to legal counsel), frequency of payments made, collateral adequacy and the borrower's financial condition. If all the criteria were met, the individual loan utilized the accounting treatment required by ASC Topic 310 with the accretable yield difference between the expected cash flows and the purchased basis accreted into income on the level yield basis over the anticipated life of the loan. If any of the six criteria were not met at the time of purchase, the loan was accounted for on the cash basis of accounting.
	The loan servicer reviews the portfolio quarterly on a loan-by-loan basis, and loans that are deemed to be impaired are charged down to their estimated value. As of June 30, 2014, approximately 72% of the loans were contractually current or less than 90 days past due, while 28% were contractually past due 90 days or more. Many of the loans were acquired in a contractually past due status, which was reflected in the discounted purchase price of the loans. Performance status is monitored on a monthly basis. The 28% of loans contractually past due includes loans in litigation and foreclosed property.

Fair_Value_Measurements_Policy

Fair Value Measurements (Policy)	6 Months Ended
	Jun. 30, 2014
Accounting Policies [Abstract]	'
Fair Value of Financial Instruments, Policy [Policy Text Block]	'
	Fair value is the price that would be received in selling an asset or paid in transferring a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact.

	GAAP requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, GAAP establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

	•	Level 1 Inputs – Unadjusted quoted prices for identical assets or liabilities in active markets that the reporting entity has the ability to access at the measurement date.

	•	Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

	•	Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
	It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. The Company is required to use observable inputs, to the extent available, in the fair value estimation process unless that data results from forced liquidations or distressed sales. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

Fair Value, by Balance Sheet Grouping [Table Text Block]	'
	The following presents the carrying amount and estimated fair value of the financial instruments held by the Company at June 30, 2014 and December 31, 2013. The information presented is subject to change over time based on a variety of factors. The operations of the Company are managed on a going concern basis and not a liquidation basis. As a result, the ultimate value realized from the financial instruments presented could be substantially different when actually recognized over time through the normal course of operations. Additionally, a substantial portion of the Company's inherent value is the Bank's capitalization and franchise value. Neither of these components has been given consideration in the presentation of fair values below.

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis, Valuation Techniques [Table Text Block]	'
	The following presents the valuation technique(s), observable inputs, and quantitative information about the unobservable inputs used for fair value measurements of the financial instruments held by the Company at June 30, 2014, categorized within Level 3 of the fair value hierarchy:


			Quantitative Information About Level 3 Fair Value Measurements
		(dollars in thousands)	Fair Value at June 30, 2014			Valuation Techniques(s)		Unobservable Input		Range of Inputs						Weighted Average
		Collateral dependent impaired loans:

		Other real estate owned	1,820			Modified appraised value		Third party appraisal		NM *			NM *			NM *

								Appraisal discount		NM *			NM *			NM *

	* Not Meaningful. Third party appraisals are obtained as to the value of the underlying asset, but disclosure of this information would not provide meaningful information, as the range will vary widely from loan to loan. Types of discounts considered include age of the appraisal, local market conditions, current condition of the property, and estimated sales costs. These discounts will also vary from loan to loan, thus providing a range would not be meaningful.
