Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Nature of operations: Principles of consolidation: Basis of financial statement presentation: Use of estimates: Cash and cash equivalents: Federal Home Loan Bank stock: Securities available for sale: Securities available for sale are carried at fair value. Unrealized gains or losses, net of the related deferred tax effect, are reported as a net amount in accumulated other comprehensive income (loss). Amortization of premiums and accretion of discounts, computed by the interest method over their contractual lives, are recognized in interest income. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Declines in the fair value of individual securities below their amortized cost that are determined to be other than temporary result in write-downs of the individual securities to their fair value, with the resulting write-downs included in current earnings as realized losses. The Company evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. The Company employs a systematic methodology that considers available evidence in evaluating potential impairment of its investments. The assessment of whether such impairment has occurred is based on management’s case-by-case evaluation of the underlying reasons for the decline in fair value. Once a decline in fair value is determined to be other than temporary, an impairment charge is recorded in investment income, and a new cost basis in the investment is established. Securities with unrealized losses that the Company deems to be other than temporary are recognized as realized losses. The assessment of whether such impairment has occurred is based on management’s case-by-case evaluation of the underlying reasons for the decline in fair value. As part of their assessment process, management determines whether (a) they do not have the intent to sell a debt security prior to recovery and (b) it is more likely than not that they will not have to sell the debt security prior to recovery, in which case the security would not be considered other than temporarily impaired, unless there is a credit loss. When management does not intend to sell the security, and it is more likely than not they will not have to sell the security before recovery of its cost basis, the Company will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. Loans held for sale: Interest rate lock commitments on mortgage loans to be funded and sold are valued at fair value and are included in other assets or liabilities, if material. Loans receivable: Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the amount of unpaid principal, reduced by an allowance for loan losses, unaccreted discount and net deferred origination fees. Interest is accrued daily on the outstanding balances. Interest on loans is generally recognized over the terms of the loans using the simple-interest method on principal amounts outstanding. The Company determines a loan to be delinquent when payments have not been made according to contractual terms, typically evidenced by nonpayment of a monthly installment by the due date. Accrual of interest is discontinued for loans at the time the loan is 90 days delinquent, unless the credit is well-secured and in the process of collection. All interest accrued but not collected for loans that are placed on nonaccrual status is reversed against interest income. Accrual of interest is generally resumed when the borrower has demonstrated the ability to make all periodic interest and principal payments. Allowance for loan losses: The allowance is an amount that management believes will be adequate to absorb estimated losses relating to specifically identified loans, as well as probable credit losses inherent in the balance of the loan portfolio, based on an evaluation of the collectability of existing loans and prior loss experience. This evaluation also takes into consideration such factors as changes in the nature and volume of the loan portfolio, the value of underlying collateral, overall portfolio quality, review of specific problem loans, and current economic conditions that may affect the borrower’s ability to pay. While management uses the best information available to make its evaluation, future adjustments to the allowance may be necessary if there are significant changes in economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses and may require the Bank to make additions to the allowance based on their judgment about information available to them at the time of their examinations. The allowance consists of specific and general components. The Company maintains a loan loss reserve for all commercial loans and agricultural operating loans in the portfolio using a risk-rating system. The calculated allowance is evaluated against the historical loss default rate for each loan type above (net of recoveries) to determine an appropriate level of allowance by loan type. Homogeneous loans with similar risk and loss characteristics are also assessed for probable losses. These loan pools include consumer, residential real estate, agricultural real estate, home equity, and vehicle loans. Historical loss default rates are multiplied by the total of each portfolio segment to determine an appropriate level of allowance by segment. The general allowance for loan losses also includes estimated losses resulting from macroeconomic factors and adjustments to account for imprecision of the loan loss model. Macroeconomic factors adjust the allowance for loan losses upward or downward based on the current point in the economic cycle and are applied to the loan loss model through a separate allowance element. The Company reviews the macroeconomic factors in order to conclude they are adequate based on current economic conditions. The specific component of the allowance for loan losses relates to loans that are considered to be impaired. A loan is impaired when it is probable, based on current information and events, 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 on an individual basis 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 Company obtains external appraisals on real estate–related impaired loans. Other valuation techniques are used as well, including internal valuations, comparable property analyses, and contractual sales information. The Company may further discount appraisal values based on their age and the relationship to the listed comparables. The amount of impairment, if any, and any subsequent changes are included in the provision for loan losses. Accrual of interest on impaired loans is discontinued when management believes the borrower’s financial condition is such that collection of interest is doubtful. Impaired loans also include loans that have been renegotiated in a troubled debt restructuring. Cash collections on impaired loans are generally credited to the loan balance, and no interest income is recognized on those loans until the principal balance has been determined to be collectible. Troubled debt restructurings: Loan origination fees and related costs: Loan servicing: Mortgage servicing rights are subject to change based primarily on changes in the mix of loans, interest rates, prepayment speeds, or default rates from the estimates used in the valuation of the mortgage servicing rights. Such changes may have a material effect on the amortization and valuation of mortgage servicing rights. Although management believes that the assumptions used to evaluate the mortgage servicing rights for impairment are reasonable, future adjustment may be necessary if future economic conditions differ substantially from the economic assumptions used to determine the value of the mortgage servicing rights. Mortgage servicing rights are periodically evaluated for impairment based on the fair value of those rights. Fair values are estimated using discounted cash flows based upon estimated prepayment speeds, ancillary income received from loan servicing, and current interest rates. For purposes of measuring impairment, the rights must be stratified by one or more predominant risk characteristics of the underlying loans. The Company stratifies its capitalized mortgage servicing rights based on interest rates and the term of the underlying loans. The amount of impairment recognized is the amount, if any, by which the amortized cost of the rights for each stratum exceeds their fair value. Foreclosed real estate: Transfers of financial assets: Core deposit intangible assets: Advertising: Premises and equipment: Comprehensive income: Income taxes: Earnings per share: Employee stock plans: Fair value of financial instruments: Cash and cash equivalents: Certificates of deposit: Federal funds sold: Securities available for sale: Federal Home Loan Bank stock: Loans held for sale: Loans and accrued interest receivable: Mortgage servicing rights: Deposits and other liabilities: Borrowed funds: Off-balance-sheet instruments: Derivatives—rate-lock commitments: The forward loan sale agreement also meets the definition of a derivative instrument. Any change in the fair value of the loan commitment after the borrower locks in the interest rate is substantially offset by the corresponding change in the fair value of the forward loan sale agreement related to such loan. The period from the time the borrower locks in the interest rate to the time the Company funds the loan and sells it to FHLMC is generally 60 days. The fair value of each instrument will rise or fall in response to changes in market interest rates subsequent to the dates the interest rate locks and forward loan sale agreements are entered into. In the event that interest rates rise after the Company enters into an interest rate lock, the fair value of the loan commitment will decline. However, the fair value of the forward loan sale agreement related to such loan commitment should increase by substantially the same amount, effectively eliminating the Company’s interest rate and price risk. At December 31, 2015, the Company had $2,142 of loan commitments outstanding related to loans being originated for sale, all of which were subject to interest rate locks and forward loan sale agreements as described above. The fair values of outstanding interest rate-lock commitments and forward sale commitments were considered immaterial to the Company’s consolidated financial statements as of December 31, 2015 and 2014, and therefore, are not recognized in the consolidated financial statements and are not included in the disclosures in Note 18. Fair value measurements: Recent accounting pronouncements: In January 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. ASU 2014-04 clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (a) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (b) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the standard requires interim and annual disclosure of both (a) the amount of foreclosed residential real estate property held by the creditor and (b) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU 2014-04 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. ASU 2014-04 permits either a modified retrospective transition method or a prospective transition method and was effective for the Company as of the beginning of the 2015 fiscal year. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU 2014-14, Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure, which requires, if certain conditions are met, an entity to derecognize a mortgage loan with a government guarantee upon foreclosure and to recognize a separate other receivable. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. This ASU will be effective for the Company for annual periods ending after December 15, 2015, using the same transition method elected under ASU 2014-04. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue Recognition – Revenue from Contracts with Customers (Topic 606). In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognitions and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 included the following changes: require equity investments to be measured at fair value with changes in fair value recognized in net income, simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities, eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements, and clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. This ASU will be effective for the Company for annual periods ending after December 15, 2018. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. Segment reporting:

Unrealized losses are deemed to be temporary. Most of these underlying securities consist of mortgage-backed securities. Market fluctuations are caused primarily by changes in interest rates and prepayments of underlying mortgages. Volatility in economic conditions influences the prices of these securities. Gross realized gains and losses, and proceeds on the sale of available-for-sale securities during the years ended December 31, 2015 and 2014 were not significant.

Specific loan terms vary as to interest rate, repayment and collateral requirements based on the type of loan requested and the creditworthiness of the prospective borrower. Credit risk tends to be geographically concentrated in that a majority of the loan customers are located in the markets serviced by the Company. The Company’s extension of credit is governed by the individual loan policies that were established to control the quality of the Company’s loans. These policies and procedures are reviewed and approved by the Board of Directors on a regular basis.

The Company utilizes an internal asset classification system as a means of reporting problem and potential problem loans. Under the Company’s risk-rating system, the Company classifies problem and potential problem loans as “Special Mention,” “Substandard” and “Doubtful,” which correspond to risk ratings five, six and seven, respectively. Substandard loans include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful, or risk-rated seven, have all the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Loans that do not currently expose the Company to sufficient risk to warrant classification in one of the aforementioned categories, but possess weaknesses that deserve management’s close attention, are deemed to be Special Mention, or risk-rated five. Risk ratings are updated any time the situation warrants. Loans not meeting the criteria above that are analyzed individually as part of the above-described process are considered to be pass-rated loans. Loans listed as not rated are included in groups of homogeneous loans with similar risk and loss characteristics. The following tables present the risk category of loans by class of loans based on the most recent analyses performed and the contractual aging as of December 31, 2015 and 2014: December 31, 2015 Special Pass Mention Substandard Doubtful Total Commercial real estate $ 29,952 $ 1,558 $ 1,425 $ - $ 32,935 Agricultural real estate 38,913 358 - - 39,271 Commercial construction real estate 2,264 - - - 2,264 Commercial operating and term 9,221 57 44 - 9,322 Agricultural operating and term 12,867 - - - 12,867 Total $ 93,217 $ 1,973 $ 1,469 $ - $ 96,659 December 31, 2014 Special Pass Mention Substandard Doubtful Total Commercial real estate $ 26,449 $ 3,556 $ 648 $ - $ 30,653 Agricultural real estate 38,128 - - - 38,128 Commercial construction real estate 4,035 - - - 4,035 Commercial operating and term 5,426 - 292 - 5,718 Agricultural operating and term 7,714 - - - 7,714 Total $ 81,752 $ 3,556 $ 940 $ - $ 86,248 For consumer, residential real estate, agricultural real estate, home equity, vehicle and residential construction loan classes, the Company collectively evaluates loans for impairment. The Company evaluates credit quality based on the aging status of the loan, which was previously presented, and by payment activity. Loans where credit quality and aging indicate potential weakness are placed on nonaccrual and are deemed to be nonperforming. Impaired loans also include loans modified in a troubled debt restructuring where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collections. The following tables present troubled debt restructurings by class of loans for the years ended December 31, 2015 and 2014: Year Ended December 31, 2015 Premodification Postmodification Number of Outstanding Outstanding Contracts Recorded Investment Recorded Investment Total debt restructuring: Residential real estate 3 $ 368 $ 368 Modified payment terms Year Ended December 31, 2014 Premodification Postmodification Number of Outstanding Outstanding Contracts Recorded Investment Recorded Investment Total debt restructuring: Residential real estate 1 $ 46 $ 46 Modified payment terms and interest rates There were no loans modified in a troubled debt restructuring that subsequently defaulted for the years ended December 31, 2015 and 2014.

Related-party loans: Loans held for sale: Interest rate lock commitments related to the origination of mortgage loans that will be sold are considered derivative instruments. The Company estimates the fair value of these derivatives using the difference between the guaranteed interest rate in the commitments and the current market interest rate. To reduce the net interest rate exposure arising from its loan sale activity, the Company enters into a commitment to sell these loans at the same time that the interest rate lock commitment is quoted. The commitments to sell loans are also considered derivative instruments, with offsetting estimated fair values based on changes in current market rates. These commitments are not designated as hedging instruments and, therefore, changes in fair value are recognized immediately into income. The fair values of the Company’s derivative instruments are offsetting and deemed to be immaterial. The net gain on the derivative instruments was $348 and $247 in 2015 and 2014, respectively, and is included in the caption, gain on sale of loans held for sale, in the consolidated statements of income.

Income Tax Matters	Note 10. Income Tax Matters The components of income tax expense are as follows: Years Ended December 31 2015 2014 Federal: Current $ 734 $ 599 Deferred 190 (147 ) 924 452 State: Current 257 220 Deferred 63 (49 ) 320 171 Total $ 1,244 $ 623 Total income tax expense differed from the amounts computed by applying the statutory U.S. federal income tax rate (35 percent) to income before income taxes as a result of the following: Years Ended December 31 2015 2014 Computed expected tax expense $ 2,148 $ 674 State income taxes, net of federal benefit 208 118 Bargain purchase gain (997 ) - Effect of graduated rates (61 ) (19 ) Other (54 ) (150 ) Income tax expense $ 1,244 $ 623 The Company utilizes a two-step process to recognize and measure uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50 percent likely of being realized upon ultimate settlement. The Company and its subsidiary file consolidated federal and state income tax returns. At December 31, 2015, the federal and Minnesota tax returns that the Company files are open for examination by taxing authorities for the years 2012, 2013 and 2014. The Company considers many factors when evaluating and estimating the Company’s tax positions, which may require periodic adjustments. At December 31, 2015, the Company did not record any liabilities for uncertain tax positions. The Company recognizes accrued penalty and interest on uncertain tax positions, if any, as a component of its income tax expense. The net deferred tax assets (liabilities) included in the accompanying consolidated balance sheets in other assets includes the following: December 31 2015 2014 Deferred tax assets: Allowance for loan losses $ 795 $ 873 Management stock bonus plan 6 6 Accrued compensation 29 15 Impairment of securities 196 196 Repossessed property 297 664 Unaccreted discount 35 48 Accrual to cash 14 - Other 144 47 Total deferred tax assets 1,516 1,849 Deferred tax liabilities: Premises and equipment 110 99 FHLB stock 130 131 Mortgage servicing rights 745 763 Deferred loan origination fees 25 31 Securities available for sale 39 58 Prepaid expenses 52 77 Accrued real estate taxes 41 40 Other 32 74 Total deferred tax liabilities 1,174 1,273 Net deferred tax assets $ 342 $ 576 Deferred tax liabilities of $241 were recorded in 2015 relating to the St. James acquisition. The total change in net deferred tax assets (excluding securities available for sale of $494) less the St. James deferred tax liabilities of $241 is the deferred tax expense of $253. Retained earnings include approximately $2,211 related to the pre-1987 allowance for loan losses for which no deferred federal income tax liability has been recognized. This amount represents an allocation of income to bad-debt deductions for tax purposes only. If the Bank no longer qualifies as a bank or in the event of a liquidation of the Bank, income would be created for tax purposes only, which would be subject to the then-current corporate income tax rate.

Banking and Thrift [Abstract]
Equity, Regulatory Capital and Dividend Restrictions	Note 11. Equity, Regulatory Capital and Dividend Restrictions The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory—and possibly additional discretionary—actions by regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the following table) of total Tier I capital and common equity Tier I capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier I capital (as defined) to average assets (as defined). Management believes, as of December 31, 2015, that the Bank meets all capital adequacy requirements to which it is subject. As of December 31, 2015, the most recent notification of the Federal Deposit Insurance Corporation categorized the Bank as “well capitalized” under the regulatory framework for Prompt Corrective Action. To be categorized as “well capitalized,” the Bank must maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios. There are no conditions or events since that notification that management believes have changed the Bank’s category. The following table summarizes the Bank’s compliance with its regulatory capital requirements: Minimum Minimum to Be for Capital Capitalized Under Actual Adequacy Prompt Corrective Amount Percent Amount Percent Amount Percent As of December 31, 2015: Tier I capital (to average assets) $ 28,734 10.48 % $ 10,967 4.00 % $ 13,709 5.00 % Common equity Tier I capital (to risk weighted assets) 28,734 14.56 % 8,884 4.50 % 12,832 6.50 % Tier I capital (to risk weighted assets) 28,734 14.56 % 11,845 6.00 % 15,793 8.00 % Total risk based capital (to risk weighted assets) 30,722 15.56 % 15,793 8.00 % 19,742 10.00 % As of December 31, 2014: Tier I capital (to average assets) 25,380 9.90 % 10,255 4.00 % 12,819 5.00 % Tier I capital (to risk weighted assets) 25,380 13.58 % 7,478 4.00 % 11,217 6.00 % Total capital (to risk weighted assets) 27,566 14.74 % 14,956 8.00 % 18,695 10.00 % In July 2013, the federal banking agencies issued a final rule revising the regulatory capital rules applicable to most national bank and federal savings associations as well as their holding companies generally beginning on January 1, 2015. The rule implements the Basel Committee’s December 2010 framework known as “Basel Ill” for strengthening international capital standards as well as certain provisions of the Dodd-Frank Act. The final rule implements a revised definition of regulatory capital, a new common equity Tier 1 minimum capital requirement of 4.50%, and a higher minimum Tier 1 capital requirement of 6.00% (which is an increase from 4.00%). Under the final rule, the total capital ratio remains at 8.00% and the minimum leverage ratio (Tier 1 capital to total assets) for all banking organizations, regardless of supervisory rating, is 4.00%. Additionally, under the final rule, in order to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers, a banking organization must hold a 2.5% capital conservation buffer composed of common equity Tier 1 capital above its minimum risk-based capital requirements. The buffer is measured relative to risk-weighted assets. The final rule also enhances risk sensitivity and addresses weaknesses identified by the regulators over recent years with the measure of risk weighted assets, including through new measures of creditworthiness to replace references to credit ratings, consistent with the requirements of the Dodd-Frank Act. Except for the largest internationally active banking organizations (which are subject to the “advanced approaches” provisions of the final rule), the new minimum capital requirements generally become effective for all banking organizations on January 1, 2015, whereas the capital conservation buffer and the deductions from common equity Tier 1 capital phase in over time, beginning on January 1, 2016 and through January 1, 2019. Similarly, non-qualifying capital instruments phase out over time.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Employee Benefit Plans	Note 13. Employee Benefit Plans Defined contribution 401(k) plan: Employee stock ownership plan: The Company makes annual discretionary contributions to the ESOP. As these funds are available, the ESOP acquires shares of Company stock and allocates the shares to ESOP participants. Dividends on allocated ESOP shares are recorded as a reduction of retained earnings. In 2015 and 2014, 6,299 and 7,570 shares, respectively, were purchased, and 2,505 and 2,839 shares, respectively, were allocated to ESOP participants at a cost of approximately $64 for both 2015 and 2014, which was charged to compensation expense. The ESOP held 91,459 and 95,602 shares of Company stock at December 31, 2015 and 2014, respectively. At December 31, 2015 and 2014, 86,135 and 89,304 shares, respectively, have been released for allocation to participants. Allocated shares held by the ESOP are treated as outstanding in computing earnings per share. The Company is subject to a put option on ESOP shares distributed to participants. The put option is a right to demand that the Company buy shares of its stock held by the participant for which there is no market. The put price is representative of the fair market value of the stock, which is approximately $31.50 and $26.50 per share per independent valuation as of December 31, 2015 and 2014, respectively. The Company must pay for the purchase within a five-year period. Since this put right is outside the control of the Company, this results in the classification of these shares as redeemable common stock in the mezzanine equity section of the balance sheet at their fair value, with changes to fair value recorded in retained earnings. The fair value of unreleased shares as of December 31, 2015 and 2014 was $168 and $167, respectively. Stock option plans: Wells Financial Corp. 2003 Stock Option Plan: Options granted under the Plan may be options that qualify as Incentive Stock Options, as defined in Section 422 of the Internal Revenue Code of 1986, as amended, or options that do not so qualify. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model. Grant-date fair values were computed using the following assumptions: estimated life (in years), risk-free interest rate, expected volatility and dividend rate. The expected volatility is based on historical volatility for the estimated term of the award. The risk-free interest rates for periods within the contractual life of the awards are based on the U.S. Treasury yield curve in effect at the time of the grant. The expected life is based on historical exercise experience. The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. Stock option activity and balances as of December 31, 2015 and 2014, and during the years then ended are presented below: Years Ended December 31 2015 2014 Aggregate Weighted- Weighted- Intrinsic Average Average Fixed Options Value Shares Exercise Price Shares Exercise Price Outstanding, beginning of year $ 9 16,950 $ 29.10 27,700 $ 29.29 Granted - - - - Exercised - - (2,850 ) 19.10 Forfeited (7,900 ) 30.00 (7,900 ) 33.38 Outstanding, end of year $ 33 9,050 $ 28.32 16,950 $ 29.10 The aggregate intrinsic value of a stock option in the table above represents the total pretax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders, had all option holders exercised their options on December 31, 2014. The intrinsic value changes based on changes in the market value of the Company’s stock. The total intrinsic value of options exercised during 2014 was $25, respectively. The Company has purchased treasury stock and uses these shares for options exercised.

The Company recorded compensation expense of $13 and $25 related to this plan for the years ended December 31, 2015 and 2014, respectively. At December 31, 2015, there was a total of $10 of unrecognized compensation expense related to stock-based compensation arrangements granted under this plan. The expense expected to be recognized is $7 in 2016 and $3 in 2017. The total tax benefit recognized in the consolidated financial statements for the years ended December 31, 2015 and 2014, related to shares granted under the plan was $11 and $17, respectively. The total tax benefit realized on the tax returns for the years ended December 31, 2015 and 2014, was $17 and $21, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 14. Commitments and Contingencies The Company leases certain branch facilities under operating leases. Some leases require the Company to pay related insurance, maintenance and repairs, and real estate taxes. The Company also has an agreement with its data processor whereby the processor agrees to provide certain data and item processing services that expire in 2020. The agreement automatically renews in five-year intervals unless terminated by either party. Future minimum rental and data processing commitments under these agreements as of December 31, 2015, are estimated as follows: Years Ending December 31, Rental Data 2016 $ 70 $ 686 2017 34 601 2018 - 558 2019 - 558 2020 - 140 Total rental expense related to operating leases was approximately $159 and $172 for the years ended December 31, 2015 and 2014, respectively. Total data processing expense related to servicing agreements was $965 and $962 for the years ended December 31, 2015 and 2014, respectively. In the normal course of business, the Company may be involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the consolidated financial statements.

Financial Instruments With Off Balance Sheet Risk [Abstract]
Financial Instruments With Off-Balance-Sheet Risk	Note 15. Financial Instruments With Off-Balance-Sheet Risk The Company is a 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 primarily commitments to extend credit. Those instruments involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amount recognized in the consolidated balance sheet. 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, standby letters of credit, and financial guarantees written is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. Commitments to extend credit on loans totaled approximately $44,081 and $38,110 at December 31, 2015 and 2014, respectively. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral held varies but normally includes real estate and personal property.

Business Combinations [Abstract]
Business Combination	Note 16. Business Combination Effective July 16, 2015, the Company completed its previously reported acquisition of St. James Federal Savings and Loan Association, St. James, Minnesota (St. James), in a conversion merger transaction. As a result of the conversion merger transaction, St. James converted from a mutual to stock institution and merged with and into the Bank, with the Bank as the surviving institution. The Company acquired 100% of the voting shares of St. James. The Company issued and sold 78,736 shares of common stock at a price of $27.36 per share, which reflected a 5% discount on the 30 day average price as prescribed in the merger agreement. The shares were offered to depositor and borrower members of St. James in a subscription offering and to stockholders of the Company and members of the general public in a community offering. The Company’s ESOP acquired 8%, or 6,299 shares, of the newly issued shares using funds borrowed from the Company. The fair value of consideration paid to the prior depositors and borrowers of St. James was determined to approximate zero. Gross offering proceeds totaled approximately $2,154, including $172 purchased by the Company’s ESOP. As a result of the stock offering, the Company had 814,758 shares of common stock outstanding as of the close of business on July 16, 2015. St. James’ sole office, located in St. James, Minnesota, has become a branch office of the Bank. The Company’s primary reasons for the acquisition are to provide for asset growth, improve capital and competitive positions, and increase the limit on loans to one borrower. The Company has determined that the acquisition constitutes a business combination as defined by the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 805, Business Combinations. Fair Value Measurements. The determination of these fair values required management to make estimates about discount rates, future expected cash flows, market conditions and other future events which are highly subjective in nature. The assets acquired and liabilities assumed in the transaction are presented at estimated fair value on the acquisition date. The Company recorded the following assets and liabilities as of July 16, 2015. The discounts and premiums resulting from the fair value adjustments will be accreted or amortized over the anticipated lives of the underlying assets and liabilities. The excess fair value of assets acquired over liabilities assumed, resulted in a $2,848 bargain purchase gain. The merger resulted in a gain because of the legal and financial barriers that St. James would have incurred to convert to a stock form of ownership in a stand-alone transaction, including the related transaction costs associated with a conversion and stock issuance. The bargain purchase gain was recorded in non-interest income in the Company’s consolidated statements of income for the three and nine months ended September 30, 2015. July 16, Recognized amounts of identifiable assets acquired and liabilities assumed Fair value of assets acquired Cash $ 1,337 Certificates of deposit 5,616 Securities – available for sale 995 Loans 17,506 Premises and equipment 366 Real estate owned 35 Accrued interest and other assets 131 Core deposit intangible 208 Total assets acquired $ 26,194 Fair value of liabilities assumed Deposits $ 23,043 Deferred tax liability 238 Accrued interest and other liabilities 65 Total liabilities assumed $ 23,346 Net assets acquired $ 2,848 The fair value of the loan portfolio was estimated by performing a discounted cash flow analysis. The valuation was performed at the loan level on real estate loans and at the cohort level for all other loan types, and is based on the objective attributes of the loans in the portfolio (e.g., the rate of interest on the loan, the original term of the loan, the current term of the loan, etc.) and current statistical performance variables used in the market place. The analysis was based on the contractually specified amounts of principal and interest to be received modified by our estimates of prepayment, default and loss severity to be experienced prospectively. The prepayment, default and loss severity assumptions were applied at the loan level based on the characteristics of the loan. The composition of the acquired loans at July 16, 2015 was as follows: Contractual Fair Value Fair Value Residential real estate $ 6,480 $ 74 $ 6,554 Revolving, open end residential real estate 336 (1 ) 335 Agricultural real estate 5,437 57 5,494 Agricultural operating and term 2,588 2 2,590 Commercial real estate 1,262 2 1,264 Automobile loans 721 (8 ) 713 Other consumer 602 (46 ) 556 Total $ 17,426 $ 80 $ 17,506 The Company estimates that $79 of the contractual amounts receivable for loans acquired will not be collected. The following table presents pro forma financial information assuming the acquisition occurred on January 1, 2014: Years Ended 2015 2014 Revenues (interest and noninterest income) $ 13,815 $ 13,026 Net income $ 2,081 $ 1,356 Diluted net income per share $ 2.43 $ 1.62 Diluted weighted-average shares $ 2.43 $ 1.62 The bargain purchase gain is excluded from the pro forma table above. To determine pro forma information, the Company adjusted its 2015 and 2014 historical results to include the historical results of St. James. Stock issuance costs incurred totaled $1,147. The stock issuance costs were offset against the proceeds of the offering, which was recognized as paid-in capital. Merger costs of $332 and $334 were expensed during the years ended December 31, 2015 and 2014, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 18. Fair Value Measurements ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer 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 shall not be 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. ASC Topic 820 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: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability 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. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Investment securities available for sale: Redeemable common stock: The Company is required, on a nonrecurring basis, to adjust the carrying value of certain assets or provide valuation allowances related to certain assets, using fair value measurements in accordance with generally accepted accounting principles.

ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not recognized at fair value on a recurring basis or nonrecurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are recognized at fair value on a recurring or nonrecurring basis are discussed above. The methodologies for financial assets and financial liabilities are discussed in Note 1. The estimated fair values of the Company’s financial instruments are as follows: December 31 2015 2014 Level in Fair Carrying Fair Carrying Fair Financial assets: Cash and cash equivalents Level 1 $ 12,059 $ 12,059 $ 14,373 $ 14,373 Certificates of deposit Level 2 9,543 9,543 4,181 4,181 Federal funds sold Level 2 9,100 9,100 2,000 2,000 Securities available for sale Level 2 34,450 34,450 34,177 34,177 FHLB stock Level 2 1,986 1,986 2,079 2,079 Loans held for sale Level 2 1,337 1,337 1,707 1,707 Loans receivable, net Level 2 197,595 199,971 182,050 183,219 Accrued interest receivable Level 2 1,020 1,020 834 834 Mortgage servicing rights Level 2 1,863 2,293 1,886 2,578 Financial liabilities: Deposits Level 2 239,950 232,350 221,972 215,199 Advances from borrowers for taxes and insurance Level 2 2,646 2,646 2,630 2,630 Accrued interest payable Level 2 12 12 17 17 Interest rate risk: The fair value of commitments to extend credit is based on fees currently charged to enter into similar agreements with comparable credit risks and the current creditworthiness of the parties. Commitments are generally short-term in nature and, if drawn upon, are issued under current market terms and conditions for credits with comparable risks. Therefore, the fair values of these financial instruments are not significant.

Securities available for sale	Securities available for sale: Securities available for sale are carried at fair value. Unrealized gains or losses, net of the related deferred tax effect, are reported as a net amount in accumulated other comprehensive income (loss). Amortization of premiums and accretion of discounts, computed by the interest method over their contractual lives, are recognized in interest income. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Declines in the fair value of individual securities below their amortized cost that are determined to be other than temporary result in write-downs of the individual securities to their fair value, with the resulting write-downs included in current earnings as realized losses. The Company evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. The Company employs a systematic methodology that considers available evidence in evaluating potential impairment of its investments. The assessment of whether such impairment has occurred is based on management’s case-by-case evaluation of the underlying reasons for the decline in fair value. Once a decline in fair value is determined to be other than temporary, an impairment charge is recorded in investment income, and a new cost basis in the investment is established. Securities with unrealized losses that the Company deems to be other than temporary are recognized as realized losses. The assessment of whether such impairment has occurred is based on management’s case-by-case evaluation of the underlying reasons for the decline in fair value. As part of their assessment process, management determines whether (a) they do not have the intent to sell a debt security prior to recovery and (b) it is more likely than not that they will not have to sell the debt security prior to recovery, in which case the security would not be considered other than temporarily impaired, unless there is a credit loss. When management does not intend to sell the security, and it is more likely than not they will not have to sell the security before recovery of its cost basis, the Company will recognize the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income.
Loans held for sale	Loans held for sale: Interest rate lock commitments on mortgage loans to be funded and sold are valued at fair value and are included in other assets or liabilities, if material.
Loans receivable	Loans receivable: Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at the amount of unpaid principal, reduced by an allowance for loan losses, unaccreted discount and net deferred origination fees. Interest is accrued daily on the outstanding balances. Interest on loans is generally recognized over the terms of the loans using the simple-interest method on principal amounts outstanding. The Company determines a loan to be delinquent when payments have not been made according to contractual terms, typically evidenced by nonpayment of a monthly installment by the due date. Accrual of interest is discontinued for loans at the time the loan is 90 days delinquent, unless the credit is well-secured and in the process of collection. All interest accrued but not collected for loans that are placed on nonaccrual status is reversed against interest income. Accrual of interest is generally resumed when the borrower has demonstrated the ability to make all periodic interest and principal payments.
Allowance for loan losses	Allowance for loan losses: The allowance is an amount that management believes will be adequate to absorb estimated losses relating to specifically identified loans, as well as probable credit losses inherent in the balance of the loan portfolio, based on an evaluation of the collectability of existing loans and prior loss experience. This evaluation also takes into consideration such factors as changes in the nature and volume of the loan portfolio, the value of underlying collateral, overall portfolio quality, review of specific problem loans, and current economic conditions that may affect the borrower’s ability to pay. While management uses the best information available to make its evaluation, future adjustments to the allowance may be necessary if there are significant changes in economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses and may require the Bank to make additions to the allowance based on their judgment about information available to them at the time of their examinations. The allowance consists of specific and general components. The Company maintains a loan loss reserve for all commercial loans and agricultural operating loans in the portfolio using a risk-rating system. The calculated allowance is evaluated against the historical loss default rate for each loan type above (net of recoveries) to determine an appropriate level of allowance by loan type. Homogeneous loans with similar risk and loss characteristics are also assessed for probable losses. These loan pools include consumer, residential real estate, agricultural real estate, home equity, and vehicle loans. Historical loss default rates are multiplied by the total of each portfolio segment to determine an appropriate level of allowance by segment. The general allowance for loan losses also includes estimated losses resulting from macroeconomic factors and adjustments to account for imprecision of the loan loss model. Macroeconomic factors adjust the allowance for loan losses upward or downward based on the current point in the economic cycle and are applied to the loan loss model through a separate allowance element. The Company reviews the macroeconomic factors in order to conclude they are adequate based on current economic conditions. The specific component of the allowance for loan losses relates to loans that are considered to be impaired. A loan is impaired when it is probable, based on current information and events, 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 on an individual basis 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 Company obtains external appraisals on real estate–related impaired loans. Other valuation techniques are used as well, including internal valuations, comparable property analyses, and contractual sales information. The Company may further discount appraisal values based on their age and the relationship to the listed comparables. The amount of impairment, if any, and any subsequent changes are included in the provision for loan losses. Accrual of interest on impaired loans is discontinued when management believes the borrower’s financial condition is such that collection of interest is doubtful. Impaired loans also include loans that have been renegotiated in a troubled debt restructuring. Cash collections on impaired loans are generally credited to the loan balance, and no interest income is recognized on those loans until the principal balance has been determined to be collectible.
Troubled debt restructurings	Troubled debt restructurings:
Loan origination fees and related costs	Loan origination fees and related costs:
Loan servicing	Loan servicing: Mortgage servicing rights are subject to change based primarily on changes in the mix of loans, interest rates, prepayment speeds, or default rates from the estimates used in the valuation of the mortgage servicing rights. Such changes may have a material effect on the amortization and valuation of mortgage servicing rights. Although management believes that the assumptions used to evaluate the mortgage servicing rights for impairment are reasonable, future adjustment may be necessary if future economic conditions differ substantially from the economic assumptions used to determine the value of the mortgage servicing rights. Mortgage servicing rights are periodically evaluated for impairment based on the fair value of those rights. Fair values are estimated using discounted cash flows based upon estimated prepayment speeds, ancillary income received from loan servicing, and current interest rates. For purposes of measuring impairment, the rights must be stratified by one or more predominant risk characteristics of the underlying loans. The Company stratifies its capitalized mortgage servicing rights based on interest rates and the term of the underlying loans. The amount of impairment recognized is the amount, if any, by which the amortized cost of the rights for each stratum exceeds their fair value.

Derivatives - rate-lock commitments	Derivatives—rate-lock commitments: The forward loan sale agreement also meets the definition of a derivative instrument. Any change in the fair value of the loan commitment after the borrower locks in the interest rate is substantially offset by the corresponding change in the fair value of the forward loan sale agreement related to such loan. The period from the time the borrower locks in the interest rate to the time the Company funds the loan and sells it to FHLMC is generally 60 days. The fair value of each instrument will rise or fall in response to changes in market interest rates subsequent to the dates the interest rate locks and forward loan sale agreements are entered into. In the event that interest rates rise after the Company enters into an interest rate lock, the fair value of the loan commitment will decline. However, the fair value of the forward loan sale agreement related to such loan commitment should increase by substantially the same amount, effectively eliminating the Company’s interest rate and price risk. At December 31, 2015, the Company had $2,142 of loan commitments outstanding related to loans being originated for sale, all of which were subject to interest rate locks and forward loan sale agreements as described above. The fair values of outstanding interest rate-lock commitments and forward sale commitments were considered immaterial to the Company’s consolidated financial statements as of December 31, 2015 and 2014, and therefore, are not recognized in the consolidated financial statements and are not included in the disclosures in Note 18.

Recent accounting pronouncements	Recent accounting pronouncements: In January 2014, the Financial Accounting Standards Board (FASB) issued ASU 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure. ASU 2014-04 clarifies that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (a) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (b) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the standard requires interim and annual disclosure of both (a) the amount of foreclosed residential real estate property held by the creditor and (b) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU 2014-04 is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. ASU 2014-04 permits either a modified retrospective transition method or a prospective transition method and was effective for the Company as of the beginning of the 2015 fiscal year. The adoption of this guidance did not have a material effect on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU 2014-14, Troubled Debt Restructurings by Creditors (Subtopic 310-40): Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure, which requires, if certain conditions are met, an entity to derecognize a mortgage loan with a government guarantee upon foreclosure and to recognize a separate other receivable. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. This ASU will be effective for the Company for annual periods ending after December 15, 2015, using the same transition method elected under ASU 2014-04. Early adoption is permitted. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue Recognition – Revenue from Contracts with Customers (Topic 606). In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognitions and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 included the following changes: require equity investments to be measured at fair value with changes in fair value recognized in net income, simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities, eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements, and clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. This ASU will be effective for the Company for annual periods ending after December 15, 2018. The adoption of this ASU is not expected to have a material impact on the Company’s consolidated financial statements.
