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 as of the March 31, 2016 and December 31, 2015. The Company’s portfolio of municipal obligations consists of both tax-exempt and taxable general obligations securities issued by various municipalities. As of March 31, 2016, 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 as of the March 31, 2016 and December 31, 2015. 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 as of the March 31, 2016 and December 31, 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 March 31, 2016 or December 31, 2015.

The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on a quarterly basis. Nonclassified 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.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	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.

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 Federal Reserve Bank 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 the lower of cost or estimated fair value, determined on an aggregate basis. 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 corresponding forward sales contracts on mortgage loans held for sale. 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 three months ended March 31, 2016 or during the year ended December 31, 2015.

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. 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 carrying value of the Company’s impaired loans was $ 7.3 6.8 75,000 88,000 Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value, determined on an aggregate basis.

Regulatory Capital Requirements

Banking and Thrift [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	8. 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 believes as of March 31, 2016, the Company and its subsidiary, Landmark National Bank (“the Bank”) meet 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. On January 1, 2015, the Company and the Bank became subject to new capital rules (the “Basel III Rules”) that implemented the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision and certain changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act. The Basel III Rules are 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 The Basel III Rules have maintained the general structure of the prompt corrective action framework, while incorporating increased requirements. The Basel III Rules include a common equity Tier 1 capital to risk-weighted assets minimum ratio of 4.5 4.0 6.0 8.0 4.0 0.625 0.625 2.5 250 As of March 31, 2016 and December 31, 2015, 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 institution’s category.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	9. Impact of Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) 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. Upon the effective date of the update, changes in the value of the Company's common stock investments will be adjustments to the income statement. Management does not expect the remaining requirements of this update to have a material impact on 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. The Company is currently evaluating the impact on the consolidated financial statements 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 is permitted. The Company is currently evaluating the impact on the consolidated financial statements and related disclosures.
