Interim Financial Statements

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Financial Statements	1. Interim Financial Statements The unaudited consolidated financial statements of Landmark Bancorp, Inc. (the “Company”) and its wholly owned subsidiaries, Landmark National Bank (the “Bank”) and Landmark Risk Management Inc., have been prepared in accordance with the instructions to Form 10-Q. Accordingly, they do not include all the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements and should be read in conjunction with the Company’s most recent Annual Report on Form 10-K, containing the latest audited consolidated financial statements and notes thereto. The consolidated financial statements in this report have not been audited by an independent registered public accounting firm, but in the opinion of management, all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of financial statements have been reflected herein. The results of the six month interim period ended June 30, 2018 are not necessarily indicative of the results expected for the year ending December 31, 2018 or any other future time period. The Company has evaluated subsequent events for recognition and disclosure up to the date the financial statements were issued. On January 1, 2018, the Company adopted ASU 2014-09 Revenue from Contracts with Customers and all subsequent amendments to the ASU (collectively, “ASC 606”), which (i) creates a single framework for recognizing revenue from contracts with customers that fall within its scope and (ii) revises when it is appropriate to recognize a gain (loss) from the transfer of non-financial assets, such as real estate owned. The majority of the Company’s revenues come from interest income and other sources, including loans, leases, securities and derivatives that are outside the scope of ASC 606. Services within the scope of ASC 606 include deposit service charges on deposits, interchange income, and the sale of real estate owned. Refer to footnote 7 to the financial statements, Revenue from Contracts with Customers, for further discussion on the Company’s accounting policies for revenue sources within the scope of ASC 606. The Company adopted ASC 606 using the modified retrospective method applied to all contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606 while prior period amounts continue to be reported in accordance with legacy GAAP. The adoption of ASC 606 did not result in a change to the accounting for any of the in-scope revenue streams. As such, no cumulative effect adjustment was recorded. In January 2016, the Financial Accounting Standards Board (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 became 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 discounted cash method previously utilized. Management has concluded that the requirements of this update do not have a material impact to the Company’s financial position, results of operations or cash flows. 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. The Company adopted ASU 2016-15 effective January 1, 2018. The adoption of ASU 2016-15 did not result in any material changes to the Company’s consolidated financial statements and related disclosures.

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 their cost basis, the Company believed that the U.S. treasury security identified in the table above was temporarily impaired as of June 30, 2018 and 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 Federal Home Loan Bank (“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 as of June 30, 2018 and December 31, 2017. The Company’s portfolio of municipal obligations consists of both tax-exempt and taxable general obligations securities issued by various municipalities. The Company did not intend to sell and it was 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 their costs. 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 June 30, 2018 and December 31, 2017. 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 (“GNMA”). 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 June 30, 2018 and December 31, 2017. The table below sets forth amortized cost and fair value of investment securities at June 30, 2018. The table 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 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 June 30, 2018 and December 31, 2017, was related to troubled debt restructurings (“TDR”) that are current and accruing interest, but still classified as impaired. Interest income recognized on a cash basis on impaired loans was immaterial during the three and six month periods ended June 30, 2018 and 2017.

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 or more delinquent and accruing interest at June 30, 2018 or December 31, 2017. The following tables present information on the Company’s past due and non-accrual loans by loan class: (Dollars in thousands) As of June 30, 2018 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 $ 100 $ 289 $ - $ 389 $ 463 $ 852 $ 137,415 Construction and land - - - - 567 567 25,886 Commercial real estate - - - - 1,793 1,793 120,153 Commercial 48 711 - 759 2,032 2,791 63,740 Agriculture 127 176 - 303 384 687 87,214 Municipal - - - - - - 3,172 Consumer 36 43 - 79 46 125 22,742 Total $ 311 $ 1,219 $ - $ 1,530 $ 5,285 $ 6,815 $ 460,322 Percent of gross loans 0.07 % 0.26 % 0.00 % 0.33 % 1.13 % 1.46 % 98.54 % (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 $ 101 $ 313 $ - $ 414 $ 552 $ 966 $ 135,249 Construction and land - 4 - 4 779 783 18,573 Commercial real estate 22 209 - 231 1,841 2,072 118,552 Commercial - 397 - 397 2,002 2,399 52,192 Agriculture - - - - 833 833 82,175 Municipal - - - - - - 3,396 Consumer 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 % 1.37 % 1.68 % 98.32 % Under the original terms of the Company’s non-accrual loans, interest earned on such loans for the six months ended June 30, 2018 and 2017 would have increased interest income by $132,000 and $63,000, respectively. No interest income related to non-accrual loans was included in interest income for the six months ended June 30, 2018 and 2017. 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 such protection is 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: (Dollars in thousands) As of June 30, 2018 As of December 31, 2017 Non-classified Classified Non-classified Classified One-to-four family residential real estate $ 137,325 $ 942 $ 135,475 $ 740 Construction and land 25,886 567 18,577 779 Commercial real estate 111,697 10,249 114,736 5,888 Commercial 58,424 8,107 52,313 2,278 Agriculture 83,390 4,511 76,455 6,553 Municipal 3,172 - 3,396 - Consumer 22,821 46 22,006 40 Total $ 442,715 $ 24,422 $ 422,958 $ 16,278 At June 30, 2018, the Company had 12 loan relationships consisting of 17 outstanding loans that were classified as TDRs. During the second quarter of 2018, the Company classified an agriculture loan totaling $64,000 as a TDR after originating a loan to an existing loan relationship that was classified as a TDR in 2016. As part of the restructuring the borrower paid off three loans previously classified as TDRs. The Company also classified a $41,000 commercial loan as a TDR after extending the maturity of the loan during the second quarter of 2018. There were no loans classified as TDRs during the first three months of 2018. Since the agriculture loan relationship was adequately secured, no impairments were recorded against the principal as of June 30, 2018. The commercial loan had a $11,000 impairment recorded against the principal balance as of June 30, 2018. During the second quarter of 2017, the Company classified two agriculture loans totaling $87,000 as TDRs after renewing loans to an existing loan relationship that was classified as a TDR in 2016. These two loans were paid off in the second quarter of 2018. During the first quarter of 2017, the Company classified an $11,000 commercial real estate loan as a TDR after extending the maturity of the loan and classified as a TDR a $15,000 agriculture loan extended to an existing loan relationship that was classified as a TDR in 2016. Since the commercial real estate loan was adequately secured, no charge-offs or impairments were recorded against the principal as of June 30, 2017. The agriculture loan relationship had a $49,000 impairment recorded against the principal balance as of June 30, 2017 and a charge-off of $215,000 was recorded in the third quarter of 2016. 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 were no loans that were classified as TDRs that defaulted within 12 months of modification during the first six months of 2018. There was one commercial real estate loan totaling $11,000 that was classified as a TDR during the second quarter of 2017 which defaulted within 12 months of modification. The loan was charged off in the fourth quarter of 2017. The Company did not record any charge-offs against loans classified as TDRs in the first six months of either 2018 or 2017. A credit provision for loan losses of $58,000 related to TDRs was recorded in the three months ended June 30, 2018. No provision for loan losses was recorded against TDRs during the three months ended June 30, 2017. A credit provision for loan losses of $91,000 and $13,000 related to TDRs was recorded in the six months ended June 30, 2018 and 2017, respectively. The Company allocated $36,000 and $127,000 of the allowance for loan losses against loans classified as TDRs at June 30, 2018 and December 31, 2017, respectively.

Fair value at June 30, 2018 was determined using discount rates ranging from 9.00% to 11.00%; prepayment speeds ranging from 6.00% to 23.83%, depending on the stratification of the specific mortgage servicing right; and a weighted average default rate of 1.35%. Fair value at December 31, 2017 was determined using discount rates ranging from 9.50% to 9.59%, prepayment speeds ranging from 5.23% to 33.39%, 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 at both June 30, 2018 and December 31, 2017, 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 did not incur any losses charged against the reserve or make any provisions to the reserve during the first six months of 2018 and 2017. As of June 30, 2018, the Company did not have any outstanding mortgage repurchase requests.

The increase in other non-interest income during the three and six months ended June 30, 2018 was primarily the result of a $525,000 recovery on a deposit-related loss that occurred in the third quarter of 2017. A description of the Company’s revenue streams within the scope of ASC 606 follows: Service Charges on Deposit Accounts The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM usage fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period during which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Interchange Income The Company earns interchange fees from debit cardholder transactions conducted through the interchange payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Gains (Losses) on Sales of Real Estate Owned The Company records a gain or loss from the sale of real estate owned when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of real estate owned to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the real estate owned asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. There were no sales of real estate owned that were financed by the Company during the first six months of 2018 or 2017.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments and Fair Value Measurements	8. 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 June 30, 2018 and December 31, 2017, including methods and assumptions utilized, are set forth below: (Dollars in thousands) As of June 30, 2018 Carrying amount Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents $ 19,883 $ 19,883 $ - $ - $ 19,883 Investment securities available-for-sale 398,137 1,952 396,185 - 398,137 Bank stocks, at cost 6,034 n/a n/a n/a n/a Loans, net 461,396 - - 480,331 480,331 Loans held for sale, net 11,764 - 11,764 - 11,764 Derivative financial instruments 695 - 695 - 695 Accrued interest receivable 4,459 20 2,279 2,160 4,459 Financial liabilities: Non-maturity deposits $ (642,106 ) $ (642,106 ) $ - $ - $ (642,106 ) Time deposits (123,185 ) - (120,775 ) - (120,775 ) FHLB borrowings (85,600 ) - (85,613 ) - (85,613 ) Subordinated debentures (21,584 ) - (19,522 ) - (19,522 ) Other borrowings (8,417 ) - (8,417 ) - (8,417 ) Derivative financial instruments (97 ) - (97 ) - (97 ) Accrued interest payable (349 ) - (349 ) - (349 ) 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 ) 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. The Company’s common stock investments are valued based on quoted exchange prices and classified as Level 1. As of January 1, 2018, the common stocks were transferred out of the available-for-sale classification. The common stock investments were sold during the second quarter of 2018. It is not practical to determine the fair value of bank stocks due to restrictions placed on the transferability of FHLB and FRB stock. Effective January 1, 2018, 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 appropriate market inputs to arrive at a discount rate that reflects exit pricing as prescribed in ASC Topic 820. The market inputs utilize market trading information in the calculation of loan fair values and is classified as Level 3. Prior to January 1, 2018, the fair value was 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 and was classified as Level 3. No adjustment was made to the interest rates for changes in credit risk of performing loans where there are no known credit concerns. The fair values of impaired loans were generally based on market prices for similar assets determined through independent appraisals or discounted values of independent appraisals and brokers’ opinions of value. The difference in methodologies may make the fair value of loans not comparable between current year and prior year periods. Mortgage loans originated and intended for sale in the secondary market are carried at fair value. The mortgage loan valuations are based on quoted secondary market prices for similar loans and are classified as Level 2. The carrying amounts 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 sales 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 amount of these fees is not material. Transfers The Company did not transfer any assets or liabilities among levels during the six months ended June 30, 2018 or during the year ended December 31, 2017. Valuation Methods for Instruments Measured at Fair Value on a Recurring Basis The following tables represent the Company’s financial instruments that are measured at fair value on a recurring basis at June 30, 2018 and December 31, 2017 allocated to the appropriate fair value hierarchy: (Dollars in thousands) As of June 30, 2018 Fair value hierarchy Total Level 1 Level 2 Level 3 Assets: Available-for-sale investment 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. The aggregate fair value, contractual balance (including accrued interest), and gain on loans held for sale were as follows: As of As of (Dollars in thousands) June 30, 2018 December 31, 2017 Aggregate fair value $ 11,764 $ 6,535 Contractual balance 11,484 6,420 Gain $ 280 $ 115 The total amount of gains from changes in fair value of loans held for sale included in earnings were as follows: Three months ended Six months ended June 30, June 30, (Dollars in thousands) 2018 2017 2018 2017 Interest income $ 98 $ 79 $ 146 $ 124 Change in fair value 264 60 165 169 Total change in fair value $ 362 $ 139 $ 311 $ 293 Valuation Methods for Instruments Measured at Fair Value on a Non-recurring 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 $9.0 million and $9.8 million, with an allocated allowance of $853,000 and $642,000, at June 30, 2018 and December 31, 2017, 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.

Regulatory Capital Requirements

Banking and Thrift [Abstract]
Regulatory Capital Requirements	9. 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 that as of June 30, 2018, the Company and the 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 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 billion). The Basel III Rules require a common equity Tier 1 capital to risk-weighted assets minimum ratio of 4.5%, a Tier 1 capital to risk-weighted assets minimum ratio of 6.0%, a Total Capital to risk-weighted assets minimum ratio of 8.0%, and a Tier 1 leverage minimum 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% effective on January 1, 2017, was 1.875% effective on January 1, 2018, and will increase to 2.5% on January 1, 2019. As of June 30, 2018 and December 31, 2017, 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. The following is a comparison of the Company’s regulatory capital to minimum capital requirements at June 30, 2018 and December 31, 2017: (Dollars in thousands) For capital Actual adequacy purposes Amount Ratio Amount Ratio (1) As of June 30, 2018 Leverage $ 94,793 10.10 % $ 37,556 4.0 % Common Equity Tier 1 Capital 73,860 12.93 % 36,426 6.4 % Tier 1 Capital 94,793 16.59 % 44,996 7.9 % Total Risk Based Capital 100,768 17.64 % 56,424 9.9 % As of December 31, 2017 Leverage $ 88,605 9.80 % $ 36,180 4.0 % Common Equity Tier 1 Capital 68,269 12.83 % 30,590 5.8 % Tier 1 Capital 88,605 16.65 % 38,571 7.3 % Total Risk Based Capital 94,208 17.71 % 49,211 9.3 % (1) The required ratios for capital adequacy purposes include a capital conservation buffer of 1.875% for June 30, 2018 and 1.25% for December 31, 2017 The following is a comparison of the Bank’s regulatory capital to minimum capital requirements at June 30, 2018 and December 31, 2017: To be well-capitalized under prompt (Dollars in thousands) For capital corrective Actual adequacy purposes action provisions Amount Ratio Amount Ratio(1) Amount Ratio As of June 30, 2018 Leverage $ 92,978 9.93 % $ 37,451 4.0 % $ 46,814 5.0 % Common Equity Tier 1 Capital 92,978 16.30 % 36,355 6.4 % 37,068 6.5 % Tier 1 Capital 92,978 16.30 % 44,909 7.9 % 45,622 8.0 % Total Risk Based Capital 98,953 17.35 % 56,314 9.9 % 57,027 10.0 % As of December 31, 2017 Leverage $ 86,808 9.62 % $ 36,097 4.0 % $ 44,105 5.0 % Common Equity Tier 1 Capital 86,808 16.35 % 30,529 5.8 % 33,222 6.5 % Tier 1 Capital 86,808 16.35 % 38,493 7.3 % 40,888 8.0 % Total Risk Based Capital 92,407 17.40 % 49,112 9.3 % 51,110 10.0 % (1) The required ratios for capital adequacy purposes include a capital conservation buffer of 1.875% for June 30, 2018 and 1.25% for December 31, 2017.

Accounting Changes and Error Corrections [Abstract]
Impact of Recent Accounting Pronouncements	10. Impact of Recent Accounting Pronouncements 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 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 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.
