No modification in 2018 or 2017 resulted in the permanent reduction of the recorded investment in the loan. Modifications involving a reduction of the stated interest rate of the loan were for periods ranging from twelve months to five years. Modifications involving an extension of the maturity date were for periods ranging from twelve months to ten years. Troubled debt restructurings during the three and nine months ended September 30, 2018 and 2017 did not result in any material charge-offs or additional provision expense. The Corporation has no allocations of specific reserves to customers whose loan terms have been modified in troubled debt restructurings as of September 30, 2018 and 2017 . The Corporation has not committed to lend additional amounts as of September 30, 2018 and 2017 to customers with outstanding loans that are classified as troubled debt restructurings. None of the charge-offs during the three and nine months ended September 30, 2018 and 2017 were of restructurings that had occurred in the previous 12 months. Credit Quality Indicators: The Corporation categorizes loans into risk categories based on relevant information about the ability of 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 Corporation analyzes loans individually by classifying the loans as to credit risk. This analysis includes non-homogeneous loans, such as commercial loans, with an outstanding balance greater than $100 thousand . Any consumer loans outstanding to a borrower who had commercial loans analyzed will be similarly risk rated. This analysis is performed on a quarterly basis. The Corporation uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and debt service capacity of the borrower or of any pledged collateral. These loans have a well-defined weakness or weaknesses which have clearly jeopardized repayment of principal and interest as originally intended. They are characterized by the distinct possibility that the institution will sustain some future loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those graded substandard, with the added characteristic that the severity of the weaknesses makes collection or liquidation in full highly questionable or improbable based upon currently existing facts, conditions, and values. Furthermore, non-homogeneous loans which were not individually analyzed, but are 90+ days past due or on non-accrual are classified as substandard. Loans included in homogeneous pools, such as residential or consumer may be classified as substandard due to 90+ days delinquency, non-accrual status, bankruptcy, or loan restructuring. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. Loans listed as not rated are either those with an outstanding balance less than $100 thousand or are included in groups of homogeneous loans. As of September 30, 2018 and December 31, 2017 , and based on the most recent analysis performed, the risk category of loans by class of loans are as follows: September 30, 2018 (Dollar amounts in thousands) Pass Special Mention Substandard Doubtful Not Rated Total Commercial Commercial & Industrial $ 462,286 $ 21,079 $ 16,145 $ — $ 8,327 $ 507,837 Farmland 88,960 7,655 8,427 — 20 105,062 Non Farm, Non Residential 172,165 5,620 10,531 — — 188,316 Agriculture 113,536 9,823 16,405 — 456 140,220 All Other Commercial 200,398 43 6,923 — 1,737 209,101 Residential First Liens 44,443 971 3,935 — 188,857 238,206 Home Equity 673 — 120 — 36,952 37,745 Junior Liens 2,041 76 171 76 45,598 47,962 Multifamily 106,891 — — — 19 106,910 All Other Residential — — 15 — 12,426 12,441 Consumer Motor Vehicle — — 674 — 317,387 318,061 All Other Consumer — — 43 — 27,028 27,071 TOTAL $ 1,191,393 $ 45,267 $ 63,389 $ 76 $ 638,807 $ 1,938,932 December 31, 2017 (Dollar amounts in thousands) Pass Special Mention Substandard Doubtful Not Rated Total Commercial Commercial & Industrial $ 430,015 $ 19,889 $ 18,611 $ 38 $ 5,947 $ 474,500 Farmland 88,338 10,782 7,466 — 10 106,596 Non Farm, Non Residential 179,181 7,689 13,632 — — 200,502 Agriculture 111,724 17,482 21,388 — 342 150,936 All Other Commercial 194,170 2,723 7,459 — 2,604 206,956 Residential First Liens 45,320 750 3,980 5 204,329 254,384 Home Equity 319 — 64 — 35,653 36,036 Junior Liens 1,882 76 342 100 39,755 42,155 Multifamily 89,936 — — — 36 89,972 All Other Residential — — 67 — 13,529 13,596 Consumer Motor Vehicle — — 731 — 301,900 302,631 All Other Consumer — — 44 — 25,301 25,345 TOTAL $ 1,140,885 $ 59,391 $ 73,784 $ 143 $ 629,406 $ 1,903,609

The investment securities portfolio is evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI model. Investment securities are generally evaluated for OTTI under FASB ASC 320, Investments - Debt and Equity Securities . However, certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, and collateralized debt obligations, that had credit ratings at the time of purchase of below AA are evaluated using the model outlined in FASB ASC 325-40, Beneficial Interests in Securitized Financial Assets. When OTTI occurs under either model, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, less any current-period credit loss. If an entity intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, less any current-period credit loss, the OTTI shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the OTTI shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. Gross unrealized losses on investment securities were $23.4 million as of September 30, 2018 and $9.5 million as of December 31, 2017 . A majority of these losses represent negative adjustments to market value relative to the interest rate environment reflecting the increase in market rates and not losses related to the creditworthiness of the issuer. Based upon our review of the issuers, we do not believe these investments to be other than temporarily impaired. Management does not intend to sell these securities and it is not more likely than not that we will be required to sell them before their anticipated recovery. There were three collateralized debt obligations securities with previously recorded OTTI but there was no additional OTTI recorded in 2018 or 2017 . During the quarter ended June 30, 2018, one of the obligations was called, resulting in the elimination of the OTTI associated with that obligation. A recovery of previously recorded OTTI of $4.2 million was received and recognized in non-interest income for the period. In addition the Corporation received $2.4 million of interest income associated with the call. During the quarter ended March 31, 2017, one of the obligations was partially called, resulting in the elimination of the OTTI associated with that obligation. A cash recovery of $3.1 million was received and recognized in non-interest income for the period as the book value of the security was previously written down to zero. Management has consistently used Standard & Poors pricing to value these investments. There are a number of other pricing sources available to determine fair value for these investments. These sources utilize a variety of methods to determine fair value. The result is a wide range of estimates of fair value for these securities. The Standard & Poors pricing was 85.57 while Moody Investor Service pricing was 21.23 , with others falling somewhere in between. We recognize that the Standard & Poors pricing utilized is an estimate, but have been consistent in using this source and its estimate of fair value.

Fair Value Disclosures [Abstract]
Fair Value	FASB ASC No. 820-10 establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) of 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 I prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The fair value of most securities available for sale is determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). For those securities that cannot be priced using quoted market prices or observable inputs a Level 3 valuation is determined. These securities are primarily trust preferred securities, which are priced using Level 3 due to current market illiquidity and certain investments in state and municipal securities. The fair value of the trust preferred securities is obtained from a third party provider without adjustment. As described previously, management obtains values from other pricing sources to validate the Standard & Poors pricing that they currently utilize. The fair value of state and municipal obligations are derived by comparing the securities to current market rates plus an appropriate credit spread to determine an estimated value. Illiquidity spreads are then considered. Credit reviews are performed on each of the issuers. The significant unobservable inputs used in the fair value measurement of the Corporation’s state and municipal obligations are credit spreads related to specific issuers. Significantly higher credit spread assumptions would result in significantly lower fair value measurement. Conversely, significantly lower credit spreads would result in a significantly higher fair value measurements. The fair value of derivatives is based on valuation models using observable market data as of the measurement date (Level 2 inputs).

They are carried at a fair value of $140 thousand , after a valuation allowance of $34 thousand at September 30, 2018 and at a fair value of $3.9 million , net of a valuation allowance of $625 thousand at December 31, 2017 . The impact to the provision for loan losses for the three months and nine months ended September 30, 2018 and for the twelve months ended December 31, 2017 was a $197 thousand decrease, a $591 thousand decrease, and a $294 thousand increase, respectively. Other real estate owned is valued at Level 3. Other real estate owned at September 30, 2018 with a value of $520 thousand was reduced $527 thousand for fair value adjustment. At September 30, 2018 other real estate owned was comprised of $303 thousand from commercial loans and $217 thousand from residential loans. Other real estate owned at December 31, 2017 with a value of $1.9 million was reduced $951 thousand for fair value adjustment. At December 31, 2017 other real estate owned was comprised of $1.7 million from commercial loans and $212 thousand from residential loans. Fair value is measured based on the value of the collateral securing those loans, and is determined using several methods. Generally the fair value of real estate is determined based on appraisals by qualified licensed appraisers. Appraisals for real estate generally use three methods to derive value: cost, sales or market comparison and income approach. The cost method bases value on the cost to replace current property. The market comparison evaluates the sales price of similar properties in the same market area. The income approach considers net operating income generated by the property and the investor’s required return. The final fair value is based on a reconciliation of these three approaches. If an appraisal is not available, the fair value may be determined by using a cash flow analysis, a broker’s opinion of value, the net present value of future cash flows, or an observable market price from an active market. Fair value of other real estate is based upon the current appraised values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant market conditions. Appraisals are obtained annually and reductions in value are recorded as a valuation through a charge to expense. The primary unobservable input used by management in estimating fair value are additional discounts to the appraised value to consider market conditions and the age of the appraisal, which are based on management’s past experience in resolving these types of properties. These discounts range from 0% to 50% . Values for non-real estate collateral, such as business equipment, are based on appraisals performed by qualified licensed appraisers or the customers financial statements. Values for non real estate collateral use much higher discounts than real estate collateral. Other real estate and impaired loans carried at fair value are primarily comprised of smaller balance properties. The following tables presents loans identified as impaired by class of loans, and carried at fair value on a non-recuring basis, as of September 30, 2018 and December 31, 2017 , which are all considered Level 3.

Carrying amount is the estimated fair value for cash and due from banks, federal funds sold, short-term borrowings, accrued interest receivable and payable, demand deposits, short-term debt and variable-rate loans or deposits that reprice frequently and fully. Security fair values were described previously. For fixed-rate, non-impaired loans or deposits, variable rate loans or deposits with infrequent repricing or repricing limits, and for longer-term borrowings, fair value is based on discounted cash flows using current market rates applied to the estimated life and considering credit risk. The valuation of impaired loans was described previously. Loan fair value estimates represent an exit price for 2018, but do not necessarily represent an exit price for years prior. Fair values of loans held for sale are based on market bids on the loans or similar loans. It was not practicable to determine the fair value of Federal Home Loan Bank stock due to restrictions placed on its transferability. Fair value of debt is based on current rates for similar financing. The fair value of off-balance sheet items is not considered material.

The amounts received under these agreements represent short-term borrowings and are reflected as a liability in the consolidated balance sheets. The securities underlying these agreements are included in investment securities in the consolidated balance sheets. The Corporation has no control over the market value of the securities, which fluctuates due to market conditions. However, the Corporation is obligated to promptly transfer additional securities if the market value of the securities falls below the repurchase agreement price. The Corporation manages this risk by maintaining an unpledged securities portfolio that it believes is sufficient to cover a decline in the market value of the securities sold under agreements to repurchase. Collateral pledged to repurchase agreements by remaining maturity are as follows: September 30, 2018 Repurchase Agreements Remaining Contractual Maturity of the Agreements (Dollar amounts in thousands) Overnight and continuous Up to 30 days 30 - 90 days Greater than 90 days Total Mortgage Backed Securities - Residential and Collateralized Mortgage Obligations $ 10,033 $ — $ 112 $ 15,535 $ 25,680 December 31, 2017 Repurchase Agreements Remaining Contractual Maturity of the Agreements (Dollar amounts in thousands) Overnight and continuous Up to 30 days 30 - 90 days Greater than 90 days Total Mortgage Backed Securities - Residential and Collateralized Mortgage Obligations $ 11,929 $ 6,282 $ 8,552 $ 758 $ 27,521

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New accounting standards	New accounting standards Accounting Pronouncements Adopted: On January 1, 2018, the Corporation 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 nonfinancial assets, such as OREO. The majority of the Corporation's revenues come from interest income and other sources, including loans, leases, securities and derivatives, that are outside the scope of ASC 606. The Corporation's services that fall within the scope of ASC 606 are presented within Non-Interest Income and are recognized as revenue as the Corporation satisfies its obligation to the customer. Services within the scope of ASC 606 include service charges on deposits, asset management fees, interchange income, and the sale of OREO. Refer to Note 8 Revenue from Contracts with Customers for further discussion on the Corporation's accounting policies for revenue sources within the scope of ASC 606. The Corporation 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 FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, amending ASU Subtopic 825-10. The amendments in this update make targeted improvements to generally accepted accounting principles (GAAP) as follows: 1) Require equity investments to be measured at fair value with changes in fair value recognized in net income.; 2) Simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment.; 3) Eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities.; 4) Eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet.; 5) Require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes.; 6) Require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments.; 7) Require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements.; and 8) Clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The amendments in this update are effective for fiscal years beginning after December 15, 2017. The Corporation adopted ASU 2016-01 on January 1, 2018 and did not have a significant impact on the financial statements. However, the fair value disclosures for our loan portfolio considers the exit price. In August of 2016 ASU 2016-15, Statement of Cash Flows (Topic 230) ("ASU 2016-15") was issued and is intended to reduce the diversity in practice around how certain transactions are classified within the statement of cash flows. ASU 2016-15 is effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted with retrospective application. The Corporation adopted ASU 2016-15 on January 1, 2018 and did not have a significant impact on its accounting and disclosures. In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. Under the new guidance, employers will present the service cost component of the net periodic benefit cost in the same income statement line item (e.g., Salaries and Benefits) as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Employers will present the other components separately (e.g., Other Noninterest Expense) from the line item that includes the service cost. ASU No. 2017-07 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption was permitted. Employers will apply the guidance on the presentation of the components of net periodic benefit cost in the income statement retrospectively. The guidance limiting the capitalization of net periodic benefit cost in assets to the service cost component will be applied prospectively. The Corporation adopted ASU 2017-07 on January 1, 2018, and did not have a significant impact on its accounting and disclosures. In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification. ASU 2017-09 was issued to provide clarity and reduce both 1) diversity in practice and 2) cost and complexity when applying the guidance in Topic 718, Compensation - Stock Compensation, to a change to the terms or conditions of a share-based payment award. Diversity in practice has arisen in part because some entities apply modification accounting under Topic 718 for modifications to terms and conditions that they consider substantive, but do not when they conclude that particular modifications are not substantive. Others apply modification accounting for any change to an award, except for changes that they consider purely administrative in nature. Still others apply modification accounting when a change to an award changes the fair value, the vesting, or the classification of the award. In practice, it appears that the evaluation of a change in fair value, vesting, or classification may be used to evaluate whether a change is substantive. ASU 2017-09 include guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. ASU 2017-09 is effective for the annual period, and interim periods within the annual periods, beginning after December 15, 2017. Early adoption was permitted, including adoption in any interim period for: (a) public business entities for reporting periods for which financial statements have not yet been issued, and (b) all other entities for reporting periods for which financial statements have not yet been made available for issuance. ASU 2017-09 should be applied prospectively to an award modified on or after the adoption date. The Corporation adopted ASU 2017-09 on January 1, 2018 on its consolidated financial statements, and did not have a significant impact on its consolidated financial statements. 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. ASU 2018-02 was issued to address the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the prohibition of backward tracing due to an income tax rate change that was initially recorded in other comprehensive income. This issue came about from the enactment of the Tax Cuts and Jobs Act on December 22, 2017 that changed the Company’s income tax rate from 35% to 21%. The ASU changed current accounting whereby an entity may elect to reclassify the stranded tax effect from accumulated other comprehensive income to retained earnings. The ASU is effective for periods beginning after December 15, 2018 although early adoption is permitted. The Corporation early adopted the standard in the first quarter of 2018 and reclassified $2.4 million from accumulated other comprehensive income to retained earnings. Recent Accounting Pronouncements: In February 2016, the FASB issued ASU No. 2016-02, Leases. Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases): 1) a lease liability, which is the present value of a lessee's obligation to make lease payments, and 2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Lessor accounting under the new guidance remains largely unchanged as it is substantially equivalent to existing guidance for sales-type leases, direct financing leases, and operating leases. Leveraged leases have been eliminated, although lessors can continue to account for existing leveraged leases using the current accounting guidance. Other limited changes were made to align lessor accounting with the lessee accounting model and the new revenue recognition standard. All entities will classify leases to determine how to recognize lease-related revenue and expense. Quantitative and qualitative disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The intention is to require enough information to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities. ASU No. 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018; early adoption is permitted. All entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. They have the option to use certain relief; full retrospective application is prohibited. The Corporation continues to evaluate the provision of the new lease standard, but due to the small number of lease agreements presently in effect for the Corporation, does not expect the new guidance will have a significant impact on the Corporation's financial statements. In June 2016 ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13), was issued and requires entities to use a current expected credit loss ("CECL") model which is a new impairment model based on expected losses rather than incurred losses. Under this model an entity would recognize an impairment allowance equal to its current estimate of all contractual cash flows that the entity does not expect to collect from financial assets measured at amortized cost. The entity's estimate would consider relevant information about past events, current conditions, and reasonable and supportable forecasts, which will result in recognition of lifetime expected credit losses upon loan origination. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted for annual reporting periods beginning after December 15, 2018. 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 overall increase is uncertain at this time. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. ASU No. 2017-04 is effective for interim and annual reporting periods beginning after December 15, 2019, applied prospectively. Early adoption is permitted for any impairment tests performed after January 1, 2017. The Corporation is assessing ASU 2017-04 but does not expect a significant impact on its accounting and disclosures. In July 2018, the FASB issued ASU No. 2018-11, Leases - Targeted Improvements, to provide entities with relief from the costs of implementing certain aspects of the new leasing standard, ASU No. 2016-02. Specifically, under the amendments in ASU 2018-11: (1) entities may elect not to recast the comparative periods presented when transitioning to the new leasing standard, and (2) lessors may elect not to separate lease and non-lease components when certain conditions are met. The amendments have the same effective date as ASU 2016-02 (January 1, 2019 for the Corporation). The Corporation expects to elect both transition options. ASU 2018-11 is not expected to have a material impact on the Corporation’s financial statements. In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU No. 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Entities are also allowed to elect early adoption the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. As ASU No. 2018-13 only revises disclosure requirements, it will not have a material impact on the Corporation’s financial statements. In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans. This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension and/or other postretirement benefit plans. ASU 2018-14 is effective for fiscal years ending after December 15, 2020; early adoption is permitted. As ASU 2018-14 only revises disclosure requirements, it will not have a material impact on the Corporation’s financial statements. In September 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This ASU requires an entity in a cloud computing arrangement (i.e., hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. Capitalized implementation costs should be presented in the same line item on the balance sheet as amounts prepaid for the hosted service, if any (generally as an “other asset”). The capitalized costs will be amortized over the term of the hosting arrangement, with the amortization expense being presented in the same income statement line item as the fees paid for the hosted service. ASU 2018-15 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. ASU 2018-15 will not have a material impact on the Corporation’s financial statements.

Business Combinations [Abstract]
Acquisitions and FDIC Indemnification Asset	Acquisitions, Divestitures and FDIC Indemnification Asset The Bank is party to a loss sharing agreement with the FDIC as a result of a 2009 acquisition. Under the loss-sharing agreement (“LSA”), the Bank will share in the losses on assets covered under the agreement (referred to as covered assets). On losses up to $29 million , the FDIC has agreed to reimburse the Bank for 80 percent of the losses. On losses exceeding $29 million , the FDIC has agreed to reimburse the Bank for 95 percent of the losses. The loss-sharing agreement is subject to following servicing procedures as specified in the agreement with the FDIC. Loans acquired that are subject to the loss-sharing agreement with the FDIC are referred to as covered loans for disclosure purposes. Since the acquisition date the Bank has been reimbursed $ 19.4 million for losses and carrying expenses and currently carries an immaterial balance in the indemnification asset. The balance of loans covered by the loss share agreement at September 30, 2018 and December 31, 2017 totaled $3.5 million and $4.3 million , respectively. The only loans still covered by the loss share agreement are the single family loans. FASB ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, applies to a loan with evidence of deterioration of credit quality since origination, acquired by completion of a transfer for which it is probable, at acquisition, that the investor will be unable to collect all contractually required payments receivable. FASB ASC 310-30 prohibits carrying over or creating an allowance for loan losses upon initial recognition. The carrying amount of loans accounted for in accordance with FASB ASC 310-30 at September 30, 2018 and 2017 are shown in the following tables: 2018 (Dollar amounts in thousands) Commercial Consumer Total Beginning balance, July 1, $ 1,598 $ — $ 1,598 Discount accretion — — — Disposals (16 ) — (16 ) ASC 310-30 Loans, September 30, $ 1,582 $ — $ 1,582 2018 (Dollar amounts in thousands) Commercial Consumer Total Beginning balance, January 1, $ 1,896 $ — $ 1,896 Discount accretion — — — Disposals (314 ) — (314 ) ASC 310-30 Loans, September 30, $ 1,582 $ — $ 1,582 2017 (Dollar amounts in thousands) Commercial Consumer Total Beginning balance, July 1, $ 1,983 $ — $ 1,983 Discount accretion — — — Disposals (47 ) — (47 ) ASC 310-30 Loans, September 30, $ 1,936 $ — $ 1,936 2017 (Dollar amounts in thousands) Commercial Consumer Total Beginning balance, January 1, $ 3,451 $ 1,430 $ 4,881 Discount accretion — — — Disposals (1,515 ) (1,430 ) (2,945 ) ASC 310-30 Loans, September 30, $ 1,936 $ — $ 1,936
