Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(1) Summary of Significant Accounting Policies Principles of Consolidation. Use of Estimates. Business Combinations. Reserve Requirements. Cash Flows. Investment Securities. The Company performs quarterly reviews of the investment portfolio to evaluate investment for other-than-temporary impairment. The initial review begins with all securities in an unrealized loss position. The Company’s assessment of other-than-temporary impairment is based on its judgment of the specific facts and circumstances impacting each individual security at the time such assessments are made. The Company reviews and considers all factual information, including expected cash flows, the structure of the security, the credit quality of the underlying assets and the current and anticipated market conditions. Any credit-related impairment on debt securities is recorded through a charge to earnings. Impairment related to other factors is recognized in other comprehensive income. However, if the Company intends to sell or it is more likely than not that it will be required to sell a security in an unrealized loss position before recovery of its amortized costs basis, the entire impairment is recorded through a charge to earnings. If an equity security is determined to be other-than-temporarily impaired, the entire impairment is recorded through a charge to earnings. Bank Stocks. Acquired Loans. Loans. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining if a loan is impaired include payment status, probability of collecting scheduled principal and interest payments when due and value of collateral for collateral dependent loans. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. In addition, the Company classifies troubled debt restructurings (“TDR”) as impaired loans. A loan is classified as a TDR if the Company modifies a loan with any concessions, as defined by accounting guidance, to a borrower experiencing financial difficulty. The allowance recorded on impaired loans is measured on a loan-by-loan basis for commercial, commercial real estate, agriculture and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of homogeneous loans with smaller individual balances are collectively evaluated for impairment. Accordingly, the Company generally does not separately identify individual consumer and residential loans for impairment disclosures. The accrual of interest on non-performing loans is discontinued at the time the loan is ninety days delinquent, unless the credit is well-secured and in process of collection. Loans are placed on non-accrual or are charged off at an earlier date if collection of the principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on non-accrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are evaluated individually and are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. Allowance for Loan Losses. In addition to the general component the allowance consists of a specific component. The specific component relates to loans that are individually classified as impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered TDRs and classified as impaired. Loans Held for Sale Mortgage loans held for sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. Mortgage Servicing Rights. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are included in amortization expense on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Transfers of Financial Assets. Mortgage Loan Repurchase Reserve. Premises and Equipment. Bank Owned Life Insurance Goodwill and Intangible Assets. Intangible assets include core deposit intangibles, lease intangibles and mortgage servicing rights. Core deposit intangible assets are amortized over their estimated useful life of ten years on an accelerated basis. Lease intangible assets are amortized over the life of the lease. When facts and circumstances indicate potential impairment, the Company will evaluate the recoverability of the intangible asset’s carrying value, using estimates of undiscounted future cash flows over the remaining asset life. Any impairment loss is measured by the excess of carrying value over fair value. Income Taxes. Loan Commitments and Related Financial Instruments. Loss Contingencies. Comprehensive Income. Real Estate Owned. Stock-Based Compensation. In the fourth quarter of 2016, the Company elected to early adopt ASU 2016-09 Compensation- Stock Compensation (Topic 718). As a result of this election, the Company recognized $116,000 and $308,000 of excess tax benefits from the exercise of stock options as a reduction in income tax expense during 2017 and 2016. Also upon early adoption of ASU 2016-09, the Company elected to change its accounting policy to account for forfeitures as they occur. The change in accounting for forfeitures did not impact the consolidated financial statements. Earnings per Share. The shares used in the calculation of basic and diluted earnings per share, which have been adjusted to give effect to the 5% common stock dividends paid by the Company in December 2017, 2016 and 2015, are shown below: (Dollars in thousands, except per share amounts) Years ended December 31, 2017 2016 2015 Net earnings available to common shareholders $ 4,369 $ 8,961 $ 10,506 Weighted average common shares outstanding - basic 4,065,291 3,997,094 3,866,829 Assumed exercise of stock options 70,640 68,568 115,450 Weighted average common shares outstanding - diluted 4,135,931 4,065,662 3,982,279 Earnings per share: Basic $ 1.07 $ 2.24 $ 2.71 Diluted $ 1.06 $ 2.20 $ 2.64 Derivative Financial Instruments.

Accounting Changes and Error Corrections [Abstract]
Impact of Recent Accounting Pronouncements	(2) Impact of Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The main provisions of the update require the identification of performance obligations within a contract and require the recognition of revenue based on a stand-alone allocation of contract revenue to each performance obligation. Performance obligations may be satisfied and revenue recognized over a period of time if: 1) the customer simultaneously receives and consumes the benefits provided by the entity’s performance as the entity performs, or 2) the entity’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced, or 3) the entity’s performance does not create an asset with an alternative use to the entity, and the entity has an enforceable right to payment for performance completed to date. For public entities the amendments of the update are effective for annual reporting periods beginning after December 15, 2017 including interim periods within that reporting period. The Company has adopted ASU 2014-09 effective January 1, 2018. The Company’s revenue is primarily comprised of net interest income on financial asset and liabilities, which are excluded from the scope of ASU 2014-09. Management has concluded that the adoption of ASU 2014-09 does not have a material impact on the Company’s financial position, results of operations or cash flows. The most significant impact of ASU 2014-09 is additional disclosures required for non-interest income. In January 2016, the FASB issued ASU 2016-01, Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Liabilities. The main provisions of the update are to eliminate the available for sale classification of accounting for equity securities and to adjust the fair value disclosures for financial instruments carried at amortized costs such that the disclosed fair values represent an exit price as opposed to an entry price. The provisions of this update will require that equity securities be carried at fair market value on the balance sheet and any periodic changes in value will be adjustments to the income statement. A practical expedient is provided for equity securities without a readily determinable fair value, such that these securities can be carried at cost less any impairment. The provisions of this update become effective for interim and annual periods beginning after December 15, 2017. The Company adopted ASU 2016-01 effective January 1, 2018. Effective January 1, 2018, changes in the value of the Company’s common stock investments are adjustments to the income statement. Additionally, the disclosure of fair value of the loan portfolio is presented using an exit price method instead of the current discounted cash flow. Management has concluded that the remaining requirements of this update do not have a material impact to the Company’s financial position, results of operations or cash flows. In February 2016, the FASB issued an update (ASU No. 2016-02, Leases) creating FASB Topic 842, Leases. The guidance is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requiring more disclosures related to leasing transactions. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. Management has concluded that based on the Company’s current operating leases, the adoption of ASU 2016-02 will not have a material impact on the Company’s consolidated financial statement and related disclosures. In March 2016, the FASB issued an update, ASU No. 2016-09, Stock Compensation: Improvements to Employee Share-Based Payment Accounting. The guidance in this update affects any entity that issues share-based payment awards including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flow. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2016. Early adoption was permitted. The Company elected to adopt ASU 2016-09 in 2016. As a result of this election, income tax expense decreased by $308,000 during 2016 as a result of recognized excess tax benefits from the exercise of stock options. The presentation of excess tax benefits from the exercise of stock options have been presented on a prospective basis and are included in changes in accrued interest and other assets in the operating activities section of the statement of cash flows. The Company’s excess tax benefits from the exercise of stock options totaled $103,000 in 2017 and $308,000 in 2016. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), commonly referred to as “CECL.” The provisions of the update eliminate the probable initial recognition threshold under current GAAP which requires reserves to be based on an incurred loss methodology. Under CECL, reserves required for financial assets measured at amortized cost will reflect an organization’s estimate of all expected credit losses over the expected term of the financial asset and thereby require the use of reasonable and supportable forecasts to estimate future credit losses. Because CECL encompasses all financial assets carried at amortized cost, the requirement that reserves be established based on an organization’s reasonable and supportable estimate of expected credit losses extends to held to maturity debt securities. Under the provisions of the update, credit losses recognized on available for sale debt securities will be presented as an allowance as opposed to a write-down. In addition, CECL will modify the accounting for purchased loans, with credit deterioration since origination, so that reserves are established at the date of acquisition for purchased loans. Under current GAAP a purchased loan’s contractual balance is adjusted to fair value through a credit discount and no reserve is recorded on the purchased loan upon acquisition. Since under CECL reserves will be established for purchased loans at the time of acquisition, the accounting for purchased loans is made more comparable to the accounting for originated loans. Finally, increased disclosure requirements under CECL oblige organizations to present the currently required credit quality disclosures disaggregated by the year of origination or vintage. FASB expects that the evaluation of underwriting standards and credit quality trends by financial statement users will be enhanced with the additional vintage disclosures. For public entities, the amendments of the update are effective beginning January 1, 2020. Management has initiated an implementation committee to assist in assessing data and system needs for the new standard. Management anticipates the effect will be an increase to the allowance for loan losses upon adoption. However, the size of the overall increase is uncertain at this time. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Payments (a consensus of Emerging Issues Task Force). This ASU attempts to clarify how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The purpose of this update is to reduce existing diversity in practice in eight areas addressed by the update. The amendments in this update are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted. Management has concluded that the adoption of ASU 2016-15 will not have a material impact on the Company’s consolidated financial statements and related disclosures. In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The amendments in this update shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The provisions of this update become effective for interim and annual periods beginning after December 15, 2018. Management has concluded that based on the Company’s current portfolio of investment securities that the adoption of these amendments will result in a shorter amortization period for investment security premiums; however, the impact will not be material to interest income on investment securities. In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 was signed into law, which among other things reduced the maximum federal corporate tax rate from 35% to 21%. This ASU addresses concerns about the guidance in current GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income (rather than in income from continuing operations). As a result of the adjustment of deferred taxes being required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects for purposes of this ASU) do not reflect the appropriate tax rate. This ASU allows for an election to reclass between retained earnings and AOCI the impact of the federal income tax rate change. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption of the amendments of this ASU is permitted. ASU 2018-02 was early adopted and the December 31, 2017 financial statements reflect the reclassification out of accumulated other comprehensive income and into retained earnings for $67,000.

The receipt of principal and interest on U.S. treasury securities is guaranteed by the full faith and credit of the U.S. government. Based on these factors, along with the Company’s intent to not sell the security and its belief that it was more likely than not that the Company will not be required to sell the security before recovery of its cost basis, the Company believed that the U.S. treasury security identified in the table above was temporarily impaired as of December 31, 2017. The Company’s U.S. federal agency portfolio consists of securities issued by the government-sponsored agencies of Federal Home Loan Mortgage Corporation (“FHLMC”), Federal National Mortgage Association (“FNMA”) and the FHLB. The receipt of principal and interest on U.S. federal agency obligations is guaranteed by the respective government-sponsored agency guarantor, such that the Company believes that its U.S. federal agency obligations do not expose the Company to credit-related losses. Based on these factors, along with the Company’s intent to not sell the securities and its belief that it was more likely than not that the Company will not be required to sell the securities before recovery of their cost basis, the Company believed that the U.S. federal agency obligations identified in the tables above were temporarily impaired. The Company’s portfolio of municipal obligations consists of both tax-exempt and taxable general obligations securities issued by various municipalities. As of December 31, 2017, the Company did not intend to sell and it is more likely than not that the Company will not be required to sell its municipal obligations in an unrealized loss position until the recovery of its cost. Due to the issuers’ continued satisfaction of the securities’ obligations in accordance with their contractual terms and the expectation that they will continue to do so, the evaluation of the fundamentals of the issuers’ financial condition and other objective evidence, the Company believed that the municipal obligations identified in the tables above were temporarily impaired. The Company’s agency mortgage-backed securities portfolio consists of securities underwritten to the standards of and guaranteed by the government-sponsored agencies of FHLMC, FNMA and the Government National Mortgage Association. The receipt of principal, at par, and interest on agency mortgage-backed securities is guaranteed by the respective government-sponsored agency guarantor, such that the Company believed that its agency mortgage-backed securities did not expose the Company to credit-related losses. Based on these factors, along with the Company’s intent to not sell the securities and the Company’s belief that it was more likely than not that the Company will not be required to sell the securities before recovery of their cost basis, the Company believed that the agency mortgage-backed securities identified in the tables above were temporarily impaired. The table below includes scheduled principal payments and estimated prepayments, based on observable market inputs, for agency mortgage-backed securities. Actual maturities will differ from contractual maturities because borrowers have the right to prepay obligations with or without prepayment penalties. The amortized cost and fair value of investment securities at December 31, 2017 are as follows: (Dollars in thousands) Amortized Estimated cost fair value Due in less than one year $ 27,070 $ 27,020 Due after one year but within five years 179,877 178,439 Due after five years but within ten years 94,632 94,663 Due after ten years 86,941 87,853 Common stocks - 8 Total $ 388,520 $ 387,983 Sales proceeds and gross realized gains and losses on sales of available-for-sale securities are as follows: (Dollars in thousands) Years ended December 31, 2017 2016 2015 Sales proceeds $ 13,810 $ 14,326 $ 30,610 Realized gains $ 522 $ 573 $ 230 Realized losses (24 ) (15 ) (349 ) Net realized gains (losses) $ 498 $ 558 $ (119 ) Securities with carrying values of $232.5 million and $224.3 million were pledged to secure public funds on deposit, repurchase agreements and as collateral for borrowings at December 31, 2017 and 2016, respectively. Except for U.S. federal agency obligations, no investment in a single issuer exceeded 10% of consolidated stockholders’ equity.

The difference between the unpaid contractual principal and the impaired loan balance is a result of charge-offs recorded against impaired loans. The difference in the Company’s non-accrual loan balances and impaired loan balances at December 31, 2017 and December 31, 2016 was related to TDRs that are current and accruing interest, but still classified as impaired. Interest income recognized on a cash basis for impaired loans was immaterial during the years 2017, 2016 and 2015.

Performing loans are considered to have a lower risk of loss. Non-accrual loans are those which the Company believes have a higher risk of loss. The accrual of interest on non-performing loans is discontinued at the time the loan is ninety days delinquent, unless the credit is well secured and in process of collection. Loans are placed on non-accrual or are charged off at an earlier date if collection of principal or interest is considered doubtful. There were no loans ninety days delinquent and accruing interest at December 31, 2017 or December 31, 2016. The following tables present information on the Company’s past due and non-accrual loans by loan class: (Dollars in thousands) As of December 31, 2017 30-59 days delinquent and accruing 60-89 days delinquent and accruing 90 days or more delinquent and accruing Total past due loans accruing Non-accrual loans Total past due and non-accrual loans Total loans not past due One-to-four family residential real estate loans $ 101 $ 313 $ - $ 414 $ 552 $ 966 $ 135,249 Construction and land loans - 4 - 4 779 783 18,573 Commercial real estate loans 22 209 - 231 1,841 2,072 118,552 Commercial loans - 397 - 397 2,002 2,399 52,192 Agriculture loans - - - - 833 833 82,175 Municipal loans - - - - - - 3,396 Consumer loans 105 204 - 309 34 343 21,703 Total $ 228 $ 1,127 $ - $ 1,355 $ 6,041 $ 7,396 $ 431,840 Percent of gross loans 0.05 % 0.26 % 0.00 % 0.31 % 1.38 % 1.68 % 98.32 % As of December 31, 2016 30-59 days delinquent and accruing 60-89 days delinquent and accruing 90 days or more delinquent and accruing Total past due loans accruing Non-accrual loans Total past due and non-accrual loans Total loans not past due One-to-four family residential real estate loans $ 215 $ 388 $ - $ 603 $ 595 $ 1,198 $ 135,648 Construction and land loans - - - - 599 599 13,139 Commercial real estate loans - - - - 300 300 117,900 Commercial loans 13 5 - 18 342 360 54,146 Agriculture loans 55 - - 55 838 893 77,431 Municipal loans - - - - - - 3,884 Consumer loans 79 3 - 82 72 154 20,117 Total $ 362 $ 396 $ - $ 758 $ 2,746 $ 3,504 $ 422,265 Percent of gross loans 0.09 % 0.09 % 0.00 % 0.18 % 0.64 % 0.82 % 99.18 % Under the original terms of the Company’s non-accrual loans, interest earned on such loans for the years 2017, 2016 and 2015, would have increased interest income by $185,000, $75,000 and $99,000, respectively. No interest income related to non-accrual loans was included in interest income for the years ended December 31, 2017, 2016 and 2015. The Company also categorizes loans into risk categories based on relevant information about the ability of the borrowers to service their debt such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on a quarterly basis. Non-classified loans generally include those loans that are expected to be repaid in accordance with contractual loan terms. Classified loans are those that are assigned a special mention, substandard or doubtful risk rating using the following definitions: Special Mention: Loans are currently protected by the current net worth and paying capacity of the obligor or of the collateral pledged but potentially weak. These loans constitute an undue and unwarranted credit risk, but not to the point of justifying a classification of substandard. The credit risk may be relatively minor, yet constitutes an unwarranted risk in light of the circumstances surrounding a specific asset. Substandard: Loans are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged. Loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans 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 as substandard, with the added characteristic that weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The following table provides information on the Company’s risk categories by loan class: As of December 31, 2017 As of December 31, 2016 (Dollars in thousands) Nonclassified Classified Nonclassified Classified One-to-four family residential real estate loans $ 135,475 $ 740 $ 135,640 $ 1,206 Construction and land loans 18,577 779 $ 13,138 600 Commercial real estate loans 114,736 5,888 111,641 6,559 Commercial loans 52,313 2,278 51,080 3,426 Agriculture loans 76,455 6,553 73,564 4,760 Municipal loans 3,396 - 3,884 - Consumer loans 22,006 40 20,181 90 Total $ 422,958 $ 16,278 $ 409,128 $ 16,641 At December 31, 2017, the Company had twelve loan relationships consisting of twenty outstanding loans totaling $4.8 million that were classified as TDRs compared to eleven relationships consisting of seventeen outstanding loans totaling $4.9 million that were classified as TDRs at December 31, 2016. During 2017, the Company classified four agriculture loans totaling $98,000 as TDRs after refinancing existing loans to two agriculture loan relationships that were classified as TDRs in 2016 and 2015. The Company also classified a $104,000 agriculture loan as a TDR in 2017 after extending the maturity of the loan. The Company also classified a one-to-four family residential real estate loan totaling $25,000 as a TDR during 2017 after modifying the terms per a bankruptcy judgment. Also during 2017, the Company classified an $11,000 commercial real estate loan as a TDR after extending the maturity of the loan. The $11,000 commercial real estate loan was charged-off during 2017 as a result of the borrower failing to comply with the terms of the restructuring. During 2016, the Company classified a $268,000 agriculture loan relationship consisting of three loans as a TDR after extending the maturities of the loans. The collateral securing the loans was deemed to be insufficient, resulting in a charge-off of $215,000. The Company also classified an $8,000 commercial loan as a TDR during 2016 after modifying the payments to interest only. Also during 2016, the Company classified an $188,000 one-to-four family residential real estate loan as a TDR after agreeing to a loan modification which adjusted the payment schedule. During 2015, the Company classified a $2.0 million commercial real estate loan relationship as a TDR after agreeing to a bankruptcy plan with the borrower. The bankruptcy plan restarted the amortization period of the loans which extended the maturities. The commercial real estate loan relationship totaled $4.4 million in 2012 when the loans were placed on non-accrual status after the borrower declared bankruptcy. The outstanding balances have been partially paid down with proceeds from asset sales and cash flows from the properties securing the loans during the bankruptcy process and under the terms of the restructuring agreement. The relationship was returned to accrual status during 2015 based on a satisfactory payment performance by the borrower under the revised terms of the bankruptcy plan. The Company also classified a $50,000 agriculture loan relationship consisting of two loans as a TDR after extending the maturity of the loans during 2015. Since all of the loans were adequately secured, no charge-offs or impairments were recorded against the principal as of December 31, 2015. During 2015, a land loan relationship consisting of three loans totaling $1.6 million, which was previously classified as a TDR during 2012, paid off with proceeds from the sale of assets and a new loan originated at market terms on the remaining assets. Also during 2015, a $78,000 commercial loan, which was classified as a TDR during 2014, paid off. The Company evaluates each TDR individually and returns the loan to accrual status when a payment history is established after the restructuring and future payments are reasonably assured. There was one commercial real estate loan totaling $11,000 that was classified as a TDR during 2017 which defaulted within 12 months of modification. The loan was charged-off as of December 31, 2017. There were no loans modified as TDRs for which there was a payment default within 12 months of modification as of December 31, 2016 and 2015. At December 31, 2017, there was a commitment of $10,000 to lend additional funds on one construction and land loan classified as a TDR. The Company recorded charge-offs of $11,000 and a credit provision for loan loss of $27,000 against TDRs during 2017. The Company recorded charge-offs of $215,000 and a provision for loan loss of $16,000 against TDRs during 2016. The Company had $80,000 of allowance for loan losses recorded against loans classified as TDRs at December 31, 2016.

Loan Commitments [Abstract]
Loan Commitments	(6) Loan Commitments The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet customers’ financing needs. These financial instruments consist principally of commitments to extend credit. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party is represented by the contractual amount of those instruments. In the normal course of business, there are various commitments and contingent liabilities, such as commitments to extend credit, letters of credit, and lines of credit, the balance of which are not recorded in the accompanying consolidated financial statements. The Company generally requires collateral or other security on unfunded loan commitments and irrevocable letters of credit. Unfunded commitments to extend credit, excluding standby letters of credit, aggregated to $87.6 million and $75.8 million at December 31, 2017 and 2016, respectively, and are generally at variable interest rates. Standby letters of credit totaled $806,000 at December 31, 2017 and $1.9 million at December 31, 2016.

Fair value at December 31, 2016 was determined using discount rates ranging from 9.50% to 9.51%, prepayment speeds ranging from 4.86% to 32.79%, depending on the stratification of the specific mortgage servicing right, and a weighted average default rate of 2.26%. The Company had a mortgage repurchase reserve of $235,000 and $301,000 at December 31, 2017 and December 31, 2016, respectively, which represents the Company’s best estimate of probable losses that the Company will incur related to the repurchase of one-to-four family residential real estate loans previously sold or to reimburse investors for credit losses incurred on loans previously sold where a breach of the contractual representations and warranties occurred. The Company charged $66,000 of losses against the mortgage repurchase reserve during 2017. The Company recovered $10,000 of losses and recorded a credit provision of $60,000 against the mortgage repurchase reserve during 2016.

Interest on any outstanding balance on the line of credit accrues at the federal funds rate plus 0.15% (1.47% at December 31, 2017). Although no loans are specifically pledged, the FHLB requires the Bank to maintain eligible collateral (qualifying loans and investment securities) that has a lending value at least equal to its required collateral. At December 31, 2017 and 2016, there was a blanket pledge of loans and securities totaling $130.6 million and $124.0 million, respectively. At December 31, 2017 and 2016, the Bank’s total borrowing capacity with the FHLB was approximately $97.5 million and $93.1 million, respectively. At December 31, 2017 and 2016, the Bank’s available borrowing capacity was $55.6 million and $38.7 million, respectively. The available borrowing capacity with the FHLB is collateral based, and the Bank’s ability to borrow is subject to maintaining collateral that meets the eligibility requirements. The borrowing capacity is not committed and is subject to FHLB credit requirements and policies. In addition, the Bank must maintain a restricted investment in FHLB stock to maintain access to borrowings.

These debentures, which are due in 2034 and are currently redeemable, were issued to a wholly owned grantor trust (the “Trust”) formed to issue preferred securities representing undivided beneficial interests in the assets of the Trust. The Trust then invested the gross proceeds of such preferred securities in the debentures. The Trust’s preferred securities and the subordinated debentures require quarterly interest payments and have variable rates, adjustable quarterly. Interest accrues at three month LIBOR plus 2.85%.

These debentures, which are due in 2036 and are currently redeemable, were issued to a wholly owned grantor trust (“Trust II”) formed to issue preferred securities representing undivided beneficial interests in the assets of Trust II. Trust II then invested the gross proceeds of such preferred securities in the debentures. Trust II’s preferred securities and the subordinated debentures require quarterly interest payments and have variable rates, adjustable quarterly. Interest accrues at three month LIBOR plus 1.34%. The interest rate at December 31, 2017 and 2016 was 2.93% and 2.30 %, respectively. In 2013, the Company assumed an additional $5.2 million of subordinated debentures as part of the Bank’s acquisition of Citizens Bank. These debentures, which are due in 2036 and are currently redeemable, were issued by Citizens Bank’s former holding company to a wholly owned grantor trust, First Capital (KS) Statutory Trust (“Trust III”) formed to issue preferred securities representing undivided beneficial interests in the assets of Trust III. Trust III’s preferred securities and the subordinated debentures require quarterly interest payments and have variable rates, adjustable quarterly. Interest accrues at three month LIBOR plus 1.62%. The interest rate at December 31, 2017 and 2016 was 3.29% and 2.62% respectively. Including the purchase accounting accretion, the effective interest rate was 7.17% at December 31, 2017 and 6.50% at December 31, 2016. While these trusts are accounted for as unconsolidated equity investments, a portion of the trust preferred securities issued by the trusts qualifies as Tier 1 Capital for regulatory purposes.

Income Tax Disclosure [Abstract]
Income Taxes	(14) Income Taxes On December 22, 2017, H.R.1, commonly known as the Tax Cuts and Jobs Act (the “Act”), was signed into law. Among other things, the Act reduces our corporate federal tax rate from 34% to 21% effective January 1, 2018. As a result, we are required to re-measure, through income tax expense, our deferred tax assets and liabilities using the enacted rate at which we expect them to be recovered or settled. The re-measurement of our net deferred tax asset resulted in additional income tax benefit of $352,000. At December 31, 2017, the company early adopted ASU 2018-02 and reclassified out of accumulated other comprehensive income and into retained earnings $67,000 of tax benefit that was recorded to income tax expense at December 22, 2017 due to re-measuring the tax rate on deferred taxes to 21% on available for sale securities. Income tax expense attributable to income from operations consisted of the following: (Dollars in thousands) Years ended December 31, 2017 2016 2015 Current: Federal $ (1,108 ) $ 1,298 $ 2,858 State (276 ) 97 431 Total current (1,384 ) 1,395 3,289 Deferred: Federal 768 797 641 State 27 248 (56 ) Total deferred 795 1,045 585 Deferred tax valuation allowance 44 (126 ) 40 Deferred tax remeasurement (352 ) - - Income tax (benefit) expense $ (897 ) $ 2,314 $ 3,914 The reasons for the difference between actual income tax expense (benefit) and expected income tax expense attributable to income from operations at the 34% statutory federal income tax rate were as follows: (Dollars in thousands) Years ended December 31, 2017 2016 2015 Computed “expected” tax expense $ 1,180 $ 3,833 $ 4,903 (Reduction) increase in income taxes resulting from: Tax-exempt interest income, net (1,346 ) (1,220 ) (1,104 ) Deferred tax remeasurement (352 ) - - REIT excise tax 249 - - Excess tax benefit from stock option exercise (107 ) (283 ) - Bank owned life insurance (316 ) (177 ) (178 ) Reversal of unrecognized tax benefits, net (197 ) (125 ) (138 ) State income taxes, net of federal benefit 61 269 412 Investment tax credits (7 ) (11 ) (11 ) Other, net (62 ) 28 30 $ (897 ) $ 2,314 $ 3,914 The tax effects of temporary differences that give rise to the significant portions of the deferred tax assets and liabilities at the following dates were as follows: (Dollars in thousands) As of December 31, 2017 2016 Deferred tax assets: Federal alternative minimum tax credit and low income housing credit carry forwards $ 2,485 $ 192 Loans, including allowance for loan losses 1,419 2,303 Net operating loss carry forwards 529 485 State taxes 413 737 Acquisition costs 224 394 Intangible assets - 100 Deferred compensation arrangements 88 158 Unrealized loss on investment securities available-for-sale 132 822 Investments 46 57 Investment impairments - 39 Other, net 46 - Total deferred tax assets 5,382 5,287 Less valuation allowance (529 ) (485 ) Total deferred tax assets, net of valuation allowance 4,853 4,802 Deferred tax liabilities: Undistributed equity earnings 1,539 - Premises and equipment, net of depreciation 454 803 Mortgage servicing rights 470 620 Prepaid expenses 210 - FHLB stock dividends 74 76 Other borrowings 35 125 Other, net 12 9 Total deferred tax liabilities 2,794 1,633 Net deferred tax asset $ 2,059 $ 3,169 The federal alternative minimum tax credit carry forward does not expire and totaled $2.4 million and $192,000 as of December 31, 2017 and 2016, respectively. The Company has Kansas corporate net operating loss carry forwards totaling $9.1 million and $10.0 million as of December 31, 2017 and 2016, respectively, which expire between 2018 and 2027. The Company has recorded a valuation allowance against the Kansas corporate net operating loss carry forwards. A valuation allowance related to the remaining deferred tax assets has not been provided because management believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets at December 31, 2017. Retained earnings at December 31, 2017 and 2016 include approximately $6.3 million for which no provision for federal income tax had been made. This amount represents allocations of income to bad debt deductions in years prior to 1988 for tax purposes only. Reduction of amounts allocated for purposes other than tax bad debt losses will create income for tax purposes only, which will be subject to the then current corporate income tax rate. The Company has unrecognized tax benefits representing tax positions for which a liability has been established. A reconciliation of the beginning and ending amount of the liability relating to unrecognized tax benefits is as follows: (Dollars in thousands) Years ended December 31, 2017 2016 Unrecognized tax benefits at beginning of year $ 1,809 $ 1,800 Gross increases to current year tax positions 50 362 Gross decreases to prior year’s tax positions (10 ) (37 ) Lapse of statute of limitations (344 ) (316 ) Unrecognized tax benefits at end of year $ 1,505 $ 1,809 Tax years that remain open and subject to audit include the years 2014 through 2017 for both federal and state tax purposes. The Company recognized $344,000 and $316,000 of previously unrecognized tax benefits during 2017 and 2016, respectively. The gross unrecognized tax benefits of $1.5 million at December 31, 2017 and $1.8 million at December 31, 2016, respectively, would favorably impact the effective tax rate by $1.2 million if recognized. During 2017, 2016 and 2015, the Company recorded $30,000, $84,000 and $55,000 respectively, of income tax expense associated with interest and penalties. As of December 31, 2017 and 2016, the Company has accrued interest and penalties related to the unrecognized tax benefits of $450,000 and $420,000, respectively which are not included in the table above. The Company believes that it is reasonably possible that a reduction in gross unrecognized tax benefits of up to $495,000 is possible during the next 12 months as a result of the lapse of the statute of limitations.

Stock Compensation Plan	(16) Stock Compensation Plan The Company has a stock-based employee compensation plan which allows for the issuance of stock options and restricted common stock, the purpose of which is to provide additional incentive to certain officers, directors, and key employees by facilitating their purchase of a stock interest in the Company. Compensation expense related to prior awards is recognized on a straight line basis over the vesting period, which is typically four or five years. The stock-based compensation cost related to these awards was $172,000, $59,000 and $16,000 for the years ended December 31, 2017, 2016 and 2015, respectively. The Company recognized tax benefits of $180,000, $330,000, and $84,000 for the years ended December 31, 2017, 2016 and 2015, respectively. For stock options, the exercise price may not be less than 100% of the fair market value of the shares on the date of the grant, and no option shall be exercisable after the expiration of ten years from the grant date. In determining compensation cost, the Black-Scholes option-pricing model is used to estimate the fair value of options on date of grant. The Black-Scholes model is a closed-end model that uses the assumptions outlined below. Expected volatility is based on historical volatility of the Company’s stock. The Company uses historical exercise behavior and other qualitative factors to estimate the expected term of the options, which represents the period of time that the options granted are expected to be outstanding. The risk-free rate for the expected term is based on U.S. Treasury rates in effect at the time of grant. At the annual meeting of stockholders on May 20, 2015, our stockholders approved the 2015 Stock Incentive Plan which authorized the issuance of equity awards covering 289,406 shares of common stock as adjusted for subsequent stock dividends. On August 1, 2016, the Company’s Compensation Committee awarded 13,671, as adjusted for subsequent stock dividends, shares of restricted common stock. These awards vest ratably over one or four years. The value of the 13,671, as adjusted for subsequent stock dividends, shares was based on a stock price of $23.35 per share on the date such shares were granted. On August 1, 2017, the Compensation Committee awarded 2,872, as adjusted for subsequent stock dividends, shares of restricted common stock and options to acquire 34,061, as adjusted for subsequent stock dividends, shares of common stock. The restricted stock awards vest ratably over one year and the value was based on a stock price of $27.86 per share on the date such shares were granted. The options vest ratably over four years.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments and Fair Value Measurements	(17) Fair Value of Financial Instruments and Fair Value Measurements Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: 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 company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Fair value estimates of the Company’s financial instruments as of December 31, 2017 and 2016, including methods and assumptions utilized, are set forth below: (Dollars in thousands) As of December 31, 2017 Carrying amount Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents $ 16,584 $ 16,584 $ - $ - $ 16,584 Investment securities available for sale 387,983 1,998 385,985 - 387,983 Bank stocks, at cost 5,423 n/a n/a n/a n/a Loans, net 433,743 - - 436,910 436,910 Loans held for sale 6,535 - 6,535 - 6,535 Derivative financial instruments 395 - 395 - 395 Accrued interest receivable 4,409 20 2,234 2,155 4,409 Financial liabilities: Non-maturity deposits $ (642,281 ) $ (642,281 ) $ - $ - (642,281 ) Time deposits (123,277 ) - (121,298 ) - (121,298 ) FHLB borrowings (31,600 ) - (31,706 ) - (31,706 ) Subordinated debentures (21,484 ) - (19,134 ) - (19,134 ) Other borrowings (13,509 ) - (13,509 ) - (13,509 ) Accrued interest payable (274 ) - (274 ) - (274 ) (Dollars in thousands) As of December 31, 2016 Carrying amount Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents $ 19,996 $ 19,996 $ - $ - $ 19,996 Investment securities available-for-sale 385,563 7,123 378,440 - 385,563 Bank stocks, at cost 5,299 n/a n/a n/a n/a Loans, net 420,461 - - 417,957 417,957 Loans held for sale 5,517 - 5,517 - 5,517 Derivative financial instruments 662 - 662 - 662 Accrued interest receivable 4,240 21 2,104 2,115 4,240 Financial liabilities: Non-maturity deposits $ (601,683 ) $ (601,683 ) $ - $ - (601,683 ) Time deposits (139,838 ) - (138,623 ) - (138,623 ) FHLB borrowings (39,100 ) - (35,695 ) - (35,695 ) Subordinated debentures (21,284 ) - (18,608 ) - (18,608 ) Other borrowings (12,483 ) - (12,483 ) - (12,483 ) Accrued interest payable (268 ) - (268 ) - (268 ) Methods and Assumptions Utilized The carrying amount of cash and cash equivalents is considered to approximate fair value. The Company’s investment securities classified as available-for-sale include U.S. treasury securities, U.S. federal agency securities, municipal obligations, agency mortgage-backed securities, certificates of deposits and common stocks. Quoted exchange prices are available for the Company’s U.S treasury securities and common stock investments, which are classified as Level 1. U.S. federal agency securities and agency 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. These measurements are classified as Level 2. Municipal securities are valued using a type of matrix, or grid, pricing in which securities are benchmarked against U.S. treasury rates based on credit rating. These model and matrix measurements are classified as Level 2 in the fair value hierarchy. It is not practical to determine the fair value of bank stocks due to restrictions placed on the transferability of FHLB and FRB stock. The estimated fair value of the Company’s loan portfolio is based on the segregation of loans by collateral type, interest terms, and maturities. The fair value is estimated based on discounting scheduled and estimated cash flows through maturity using an appropriate risk-adjusted yield curve to approximate current interest rates for each category. No adjustment was made to the interest rates for changes in credit risk of performing loans where there are no known credit concerns. Management segregates loans in appropriate risk categories. Management believes that the risk factor embedded in the interest rates along with the allowance for loan losses applicable to the performing loan portfolio results in a fair valuation of such loans. The fair values of impaired loans are generally based on market prices for similar assets determined through independent appraisals or discounted values of independent appraisals and brokers’ opinions of value. This method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC Topic 820 and is classified as Level 3. Mortgage loans originated and intended for sale in the secondary market are carried at estimated fair value. The mortgage loan valuations are based on quoted secondary market prices for similar loans and are classified as Level 2. The carrying amount of accrued interest receivable and payable are considered to approximate fair value. The estimated fair value of deposits with no stated maturity, such as non-interest-bearing demand deposits, savings, money market accounts, and checking accounts, is equal to the amount payable on demand. The fair value of interest-bearing time deposits is based on the discounted value of contractual cash flows of such deposits. The discount rate is tied to the FHLB yield curve plus an appropriate servicing spread. Fair value measurements based on discounted cash flows are classified as Level 2. These fair values do not incorporate the value of core deposit intangibles which may be associated with the deposit base. The fair value of advances from the FHLB, subordinated debentures, and other borrowings is estimated using current yield curves for similar borrowings adjusted for the Company’s current credit spread and classified as Level 2. The Company’s derivative financial instruments consist of interest rate lock commitments and forward commitments for the future delivery of these mortgage loans. The fair values of these derivatives are based on quoted prices for similar loans in the secondary market. The market prices are adjusted by a factor, based on the Company’s historical data and its judgment about future economic trends, which considers the likelihood that a commitment will ultimately result in a closed loan. These instruments are classified as Level 2. The amounts are included in other assets or other liabilities on the consolidated balance sheets and gains on sale of loans, net in the consolidated statements of earnings. Off-Balance-Sheet Financial Instruments The fair value of letters of credit and commitments to extend credit is based on the fees currently charged to enter into similar agreements. The aggregate of these fees is not material. Transfers The Company did not transfer any assets or liabilities among levels during the year ended December 31, 2017 or 2016. Valuation Methods for Instruments Measured at Fair Value on a Recurring Basis The following table represents the Company’s financial instruments that are measured at fair value on a recurring basis at December 31, 2017 and 2016, allocated to the appropriate fair value hierarchy: (Dollars in thousands) As of December 31, 2017 Fair value hierarchy Total Level 1 Level 2 Level 3 Assets: Available-for-sale securities U.

Other-than-temporary impairment 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 of that security’s cost basis. Changes in the fair value of mortgage loans originated and intended for sale in the secondary market and derivative financial instruments are included in gains on sales of loans. The aggregate fair value, contractual balance (including accrued interest), and gain or loss on loans held for sale were as follows: As of December 31, (Dollars in thousands) 2017 2016 Aggregate fair value $ 6,535 $ 5,517 Contractual balance 6,420 5,480 Gain $ 115 $ 37 The total amount of gains and losses from changes in fair value of loans held for sale included in earnings were as follows: As of December 31, (Dollars in thousands) 2017 2016 Interest income $ 259 $ 361 Change in fair value 78 (243 ) Total change in fair value $ 337 $ 118 Valuation Methods for Instruments Measured at Fair Value on a Nonrecurring Basis The Company does not value its loan portfolio at fair value. Collateral-dependent impaired loans are generally carried at the lower of cost or fair value of the collateral, less estimated selling costs. Collateral values are determined based on appraisals performed by qualified licensed appraisers hired by the Company and then further adjusted if warranted based on relevant facts and circumstances. The appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales and income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Impaired loans are reviewed and evaluated at least quarterly for additional impairment and adjusted accordingly, based on the same factors identified above. The loan balance of the Company’s impaired loans was $9.8 million and $6.7 million, with an allocated allowance of $642,000 and $274,000, at December 31, 2017 and 2016, respectively. Real estate owned includes assets acquired through, or in lieu of, foreclosure and land previously acquired for expansion. Real estate owned is initially recorded at the fair value of the collateral less estimated selling costs. Subsequent valuations are updated periodically and are based upon independent appraisals, third party price opinions or internal pricing models. The appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales and income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Real estate owned is reviewed and evaluated at least annually for additional impairment and adjusted accordingly, based on the same factors identified above. The following table represents the Company’s financial instruments that are measured at fair value on a non-recurring basis as of December 31, 2017 and 2016 allocated to the appropriate fair value hierarchy: (Dollars in thousands) As of December 31, 2017 Total Fair value hierarchy (losses)/ Total Level 1 Level 2 Level 3 gains Assets: Impaired loans: One-to-four family residential real estate $ 171 $ - $ - $ 171 $ (73 ) Construction and land 1,499 - - 1,499 (102 ) Commercial real estate loans 33 - - 33 12 Commercial loans 1,600 - - 1,600 (304 ) Agriculture loans 264 - - 264 65 Real estate owned: One-to-four family residential real estate 325 - - 325 (68 ) Commercial real estate 85 - - 85 (50 ) As of December 31, 2016 Total Fair value hierarchy (losses)/ Total Level 1 Level 2 Level 3 gains Assets: Impaired loans: Commercial real estate loans $ 219 $ - $ - $ 219 $ (81 ) Commercial loans 222 - - 222 (87 ) Agriculture loans 645 - - 645 (89 ) Real estate owned: One-to-four family residential real estate 142 - - 142 (34 ) The following table presents quantitative information about Level 3 fair value measurements for impaired loans measured at fair value on a non-recurring basis as of December 31, 2017 and 2016.

Regulatory Capital Requirements

Regulatory Capital Requirements	12 Months Ended

Banking and Thrift [Abstract]
Regulatory Capital Requirements	(18) Regulatory Capital Requirements Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Management believed as of December 31, 2017, the Company and Bank met all capital adequacy requirements to which they were subject at that time. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. The Company and the Bank are subject to the Basel III Rule, which is applicable to all U.S. banks that are subject to minimum capital requirements, as well as to bank and savings and loan holding companies other than “small bank holding companies” (generally, non-public bank holding companies with consolidated assets of less than $1.0 billion). The Basel III Rule includes a common equity Tier 1 capital to risk-weighted assets minimum ratio of 4.5%, a minimum ratio of Tier 1 capital to risk-weighted assets of 6.0%, a minimum ratio of Total Capital to risk-weighted assets of 8.0%, and a minimum Tier 1 leverage ratio of 4.0%. A capital conservation buffer, comprised of common equity Tier 1 capital, is also established above the regulatory minimum capital requirements. This capital conservation buffer began on January 1, 2016 at 0.625% of risk-weighted assets, was 1.25% for 2017, and will increase each subsequent year by an additional 0.625% until reaching its final level of 2.5% on January 1, 2019. The capital conservation buffer increases the common equity Tier 1 capital ratio, Tier 1 capital and total risk based capital ratios. As of December 31, 2017 and December 31, 2016, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action then in effect. There are no conditions or events since that notification that management believes have changed the Bank’s category.

At December 31, 2017, the Bank could distribute dividends of up to $16.2 million without regulatory approvals. The primary source of funds for the Company is dividends from the Bank. Under the National Bank Act, a national bank may pay dividends out of its undivided profits in such amounts and at such times as the bank’s board of directors deems prudent. Without prior OCC approval, however, a national bank may not pay dividends in any calendar year that, in the aggregate, exceed the bank’s year-to-date net income plus the bank’s retained net income for the two preceding years. The payment of dividends by any financial institution is affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a financial institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	(20) Commitments, Contingencies and Guarantees Commitments to extend credit are legally binding agreements to lend to a borrower providing there are no violations of any conditions established in the contract. The Company, as a provider of financial services, routinely issues financial guarantees in the form of financial and performance commercial and standby letters of credit. As many of the commitments are expected to expire without being drawn upon, the total commitment does not necessarily represent future cash requirements (see Note 6). There are no pending legal proceedings to which the Company or the Bank is a party other than ordinary routine litigation incidental to the Bank’s business. While the ultimate outcome of current legal proceedings cannot be predicted with certainty, it is the opinion of management that the resolution of these legal actions should not have a material effect on the Company’s consolidated financial position or results of operations.

Deposit-related Loss
Deposit-Related Loss	(21) Deposit-Related Loss On August 8, 2017, the Company was made aware that checks deposited by our customer from a third party were being returned by another financial institution due to uncollected funds related to the third party. This caused a $10.3 million overdraft balance. As of December 31, 2017, the Company’s collection efforts have provided $2.2 million in funds to cover a portion of the overdraft, resulting in an $8.1 million pre-tax loss which is included in other non-interest expense in the consolidated statement of earnings. An investigation of the situation and the potential recovery of losses is ongoing, including whether or not existing insurance policies will cover any of the loss. The Company intends to protect all of its rights pursuant to this matter and seek all available legal and equitable remedies; however, future recoveries are uncertain. The recovery process is expected to require an extended period of time to resolve, and the Company will likely incur further legal expenses in pursuing our recovery efforts.

The Company reviews and considers all factual information, including expected cash flows, the structure of the security, the credit quality of the underlying assets and the current and anticipated market conditions. Any credit-related impairment on debt securities is recorded through a charge to earnings. Impairment related to other factors is recognized in other comprehensive income. However, if the Company intends to sell or it is more likely than not that it will be required to sell a security in an unrealized loss position before recovery of its amortized costs basis, the entire impairment is recorded through a charge to earnings. If an equity security is determined to be other-than-temporarily impaired, the entire impairment is recorded through a charge to earnings.

Loans	Loans. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining if a loan is impaired include payment status, probability of collecting scheduled principal and interest payments when due and value of collateral for collateral dependent loans. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. In addition, the Company classifies troubled debt restructurings (“TDR”) as impaired loans. A loan is classified as a TDR if the Company modifies a loan with any concessions, as defined by accounting guidance, to a borrower experiencing financial difficulty. The allowance recorded on impaired loans is measured on a loan-by-loan basis for commercial, commercial real estate, agriculture and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Large groups of homogeneous loans with smaller individual balances are collectively evaluated for impairment. Accordingly, the Company generally does not separately identify individual consumer and residential loans for impairment disclosures. The accrual of interest on non-performing loans is discontinued at the time the loan is ninety days delinquent, unless the credit is well-secured and in process of collection. Loans are placed on non-accrual or are charged off at an earlier date if collection of the principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on non-accrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are evaluated individually and are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Loan Losses	Allowance for Loan Losses. In addition to the general component the allowance consists of a specific component. The specific component relates to loans that are individually classified as impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered TDRs and classified as impaired.
Loans Held for Sale	Loans Held for Sale Mortgage loans held for sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
Mortgage Servicing Rights	Mortgage Servicing Rights. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are included in amortization expense on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.

Goodwill and Intangible Assets	Goodwill and Intangible Assets. Intangible assets include core deposit intangibles, lease intangibles and mortgage servicing rights. Core deposit intangible assets are amortized over their estimated useful life of ten years on an accelerated basis. Lease intangible assets are amortized over the life of the lease. When facts and circumstances indicate potential impairment, the Company will evaluate the recoverability of the intangible asset’s carrying value, using estimates of undiscounted future cash flows over the remaining asset life. Any impairment loss is measured by the excess of carrying value over fair value.
