Accounting Policies [Abstract]
BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES	BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES: BUSINESS Organization: The consolidated financial statements of First Financial Corporation and its subsidiaries (the Corporation) include the parent company and its wholly-owned subsidiaries, First Financial Bank, N.A. headquartered in Vigo County, Indiana, The Morris Plan Company of Terre Haute (Morris Plan), First Chanticleer Corporation, a property rental entity headquartered in Terre Haute, Indiana, and FFB Risk Management Co., Inc., a captive insurance subsidiary headquartered in Las Vegas, Nevada. Inter-company transactions and balances have been eliminated. First Financial Bank also has two investment subsidiaries, Portfolio Management Specialists A (Specialists A) and Portfolio Management Specialists B (Specialists B), which were established to hold and manage certain assets as part of a strategy to better manage various income streams and provide opportunities for capital creation as needed. Specialists A and Specialists B subsequently entered into a limited partnership agreement, Global Portfolio Limited Partners. Portfolio Management Specialists B also owns First Financial Real Estate, LLC. At December 31, 2019 , $784.4 million of securities and loans were owned by these subsidiaries. Specialists A, Specialists B, Global Portfolio Limited Partners and First Financial Real Estate LLC are included in the consolidated financial statements. The Corporation, which is headquartered in Terre Haute, Indiana, offers a wide variety of financial services including commercial, mortgage and consumer lending, lease financing, trust account services and depositor services through its four subsidiaries. The Corporation's primary source of revenue is derived from loans to customers and investment activities. The Corporation operates 82 branches in west-central Indiana, east-central Illinois, western Kentucky, and middle and western Tennessee. First Financial Bank is the largest bank in Vigo County. It operates ten full-service banking branches within the county; one in Daviess County, Indiana.; three in Clay County, Indiana; one in Greene County, Indiana; two in Knox County, Indiana; four in Parke County, Indiana; one in Putnam County, Indiana; four in Sullivan County, Indiana; one in Vanderburgh County, Indiana,; four in Vermillion County, Indiana; four in Champaign County, Illinois; one in Clark County, Illinois; three in Coles County, Illinois; two in Crawford County, Illinois; two in Franklin County, Illinois; one in Jasper County, Illinois; two in Jefferson County, Illinois; one in Lawrence County, Illinois; two in Livingston County, Illinois; two in Marion County, Illinois; three in McLean County, Illinois; two in Richland County, Illinois; six in Vermilion County, Illinois; one in Wayne County, Illinois; two in Calloway County, Kentucky; three in Christian County, Kentucky; two in Fulton County, Kentucky; two in Marshall County, Kentucky; one in Todd County, Kentucky; one in Trigg County, Kentucky; three in Cheatham County, Tennessee; one in Houston County, Tennessee; and three in Montgomery County, Tennessee. There are three loan production offices, one in Marion County, Indiana; one in Rutherford County, Tennessee; and one in Williamson County, Tennessee. The bank also has a main office in downtown Terre Haute and an operations center/office building in southern Terre Haute. Regulatory Agencies: First Financial Corporation is a multi-bank holding company and as such is regulated by various banking agencies. The holding company is regulated by the Seventh District of the Federal Reserve System. The national bank subsidiary is regulated by the Office of the Comptroller of the Currency. The state bank subsidiary is jointly regulated by the state banking organization and the Federal Deposit Insurance Corporation. FFB Risk Management Company is regulated by the State of Nevada Division of Insurance. SIGNIFICANT ACCOUNTING POLICIES Use of Estimates: To prepare financial statements in conformity with U.S. generally accepted accounting principles, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ. Cash Flows : Cash and cash equivalents include cash and demand deposits with other financial institutions. Cash flows are reported for customer loan and deposit transactions and short-term borrowings. Non-cash transactions include loans transferred to other real estate of $0.5 million , $0.6 million and $0.9 million for the years ended December 31, 2019 , 2018 and 2017 respectively. Additionally, there was a non-cash transaction for lease liabilities arising from obtaining right-of-use assets of $6.7 million for the year ended December 31, 2019. Securities : The Corporation classifies all securities as "available for sale." Securities are classified as available for sale when they might be sold before maturity. Securities available for sale are carried at fair value with unrealized holdings gains and losses, net of taxes, reported in other comprehensive income within shareholders' equity. Interest income includes amortization of purchase premium or discount. Premiums and discounts are amortized on the level yield method without anticipating prepayments. Mortgage-backed securities are amortized over the expected life. Realized gains and losses on sales are based on the amortized cost of the security sold. Management evaluates securities for other-than temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Loans: Loans that management has the intent and ability to hold for the foreseeable future until maturity or pay-off are reported at the principal balance outstanding, net of unearned interest, purchase premiums and discounts, deferred loan fees and costs, and allowance for loan losses. Loans held for sale are reported at the lower of cost or fair value, on an aggregate basis. Interest income is accrued on the unpaid principal balance and includes amortization of net deferred loan fees and costs over the loan term without anticipating prepayments. The recorded investment in loans includes accrued interest receivable and net deferred loan fees and costs. Interest income is not reported when full loan repayment is in doubt, typically when the loan is impaired or payments are significantly past due. Past-due status is based on the contractual terms of the loan. All interest accrued but not received for loans placed on non-accrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. In all cases, loans are placed on non-accrual or charged-off if collection of principal or interest is considered doubtful. The above policies are consistent for all segments of loans. Certain Purchased Loans: The Corporation purchases individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased loans are recorded at the amount paid, such that there is no carryover of the seller's allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchased loans are accounted for individually. The Corporation estimates the amount and timing of expected cash flows for each purchased loan, and the expected cash flows in excess of amount paid are recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a provision for loan loss is recorded. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income. Concentration of Credit Risk: Most of the Corporation's business activity is with customers located within west central Indiana and east central Illinois. Therefore, the Corporation's exposure to credit risk is significantly affected by changes in the economy of this area. A major economic downturn in this area would have a negative effect on the Corporation's loan portfolio. The risk characteristics of each loan portfolio segment are as follows: Commercial Commercial loans are predominately loans to expand a business or finance asset purchases. The underlying risk in the Commercial loan segment is primarily a function of the reliability and sustainability of the cash flows of the borrower and secondarily on the underlying collateral securing the transaction. From time to time, the cash flows of borrowers may be less than historical or as planned. In addition, the underlying collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets financed or other business assets and most commercial loans are further supported by a personal guarantee. However, in some instances, short term loans are made on an unsecured basis. Agriculture production loans are typically secured by growing crops and generally secured by other assets such as farm equipment. Production loans are subject to weather and market pricing risks. The Corporation has established underwriting standards and guidelines for all commercial loan types. The Corporation strives to maintain a geographically diverse commercial real estate portfolio. Commercial real estate loans are primarily underwritten based upon the cash flows of the underlying real estate or from the cash flows of the business conducted at the real estate. Generally, these types of loans will be fully guaranteed by the principal owners of the real estate and loan amounts must be supported by adequate collateral value. Commercial real estate loans may be adversely affected by factors in the local market, the regional economy, or industry specific factors. In addition, Commercial Construction loans are a specific type of commercial real estate loan which inherently carry more risk than loans for completed projects. Since these types of loans are underwritten utilizing estimated costs, feasibility studies, and estimated absorption rates, the underlying value of the project may change based upon the inaccuracy of these projections. Commercial construction loans are closely monitored, subject to industry standards, and disbursements are controlled during the construction process. Residential Retail real estate mortgages that are secured by 1-4 family residences are generally owner occupied and include residential real estate and residential real estate construction loans. The Corporation typically establishes a maximum loan-to-value ratio and generally requires private mortgage insurance if the ratio is exceeded. The Corporation sells substantially all of its long-term fixed mortgages to secondary market purchasers. Mortgages sold to secondary market purchasers are underwritten to specific guidelines. The Corporation originates some mortgages that are maintained in the bank’s loan portfolio. Portfolio loans are generally adjustable rate mortgages and are underwritten to conform to Qualified Mortgage standards. Several factors are considered in underwriting all Mortgages including the value of the underlying real estate, debt-to-income ratio and credit history of the borrower. Repayment is primarily dependent upon the personal income of the borrower and can be impacted by changes in borrower’s circumstances such as changes in employment status and changes in real estate property values. Risk is mitigated by the sale of substantially all long-term fixed rate mortgages, the underwriting of portfolio loans to Qualified Mortgage standards and the fact that mortgages are generally smaller individual amounts spread over a large number of borrowers. Consumer The consumer portfolio primarily consists of home equity loans and lines (typically secured by a subordinate lien on a 1-4 family residence), secured loans (typically secured by automobiles, boats, recreational vehicles, or motorcycles), cash/CD secured, and unsecured loans. Pricing, loan terms, and loan to value guidelines vary by product line. The underlying value of collateral dependent loans may vary based on a number of economic conditions, including fluctuations in home prices and unemployment levels. Underwriting of consumer loans is based on the individual credit profile and analysis of the debt repayment capacity for each borrower. Payments for consumer loans is typically set-up on equal monthly installments, however, future repayment may be impacted by a change in economic conditions or a change in the personal income levels of individual customers. Overall risks within the consumer portfolio are mitigated by the mix of various loan products, lending in various markets and the overall make-up of the portfolio (small loan sizes and a large number of individual borrowers). Allowance for Loan Losses: The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management's judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-classified loans as well as non-impaired classified loans and is based on historical loss experience adjusted for current factors. A loan is impaired when full payment under the loan terms is not expected. Loans for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Impairment is evaluated in total for smaller-balance loans of similar nature such as residential mortgages and consumer loans, and on an individual basis for other loans. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows, using the loan's existing rate, or at the fair value of collateral if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment and, accordingly, they are not separately identified for impairment disclosures. The general component covers non-classified loans as well as non-impaired classified loans and is based on historical loss experience adjusted for current factors. The historical loss experience is based on the actual loss history experienced over the most recent four years. This actual loss experience is supplemented with other current factors based on the risks present for each portfolio segment. These current factors include consideration of the following: levels of and trends in delinquent, classified, and impaired loans; levels of and trends in charge-offs and recoveries; national and local economic trends and conditions; changes in lending policies and procedures; trends in volume and terms of loans; experience, ability, and depth of lending management and other relevant staff; credit concentrations; value of underlying collateral for collateral dependent loans; and other external factors such as competition and legal and regulatory requirements. The following portfolio segments have been identified: commercial loans, residential loans and consumer loans. A characteristic of the commercial loan segment is that the loans are for business purchases. A characteristic of the residential loan segment is that the loans are secured by residential properties. A characteristic of the consumer loan segment is that the loans are for automobiles and other consumer purchases. Commercial loans are generally well secured, which mitigates the risk of loss and has contributed to the low historical loss rate. However, concentrations in commercial real estate, along with the potential impact of rising interest rates to commercial real estate, raises the risk of loss on commercial loans. For these reasons, commercial loans have the highest adjustment to the historical loss rate. Continued weakness in local economic conditions along with declining auto values resulted in consumer loans having the next highest level of adjustment to the historical loss rate. The residential loan portfolio segment had the lowest level of adjustment to the historical loss rate. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Corporation determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. Foreclosed Assets: Assets acquired through or instead of loan foreclosures are initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or similar legal agreement. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines, a valuation allowance is recorded through expense. Costs after acquisition are expensed. Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed over the useful lives of the assets, which range from 3 to 5 years for furniture and equipment and 33 to 39 years for buildings and leasehold improvements. Restricted Stock: Restricted stock includes Federal Home Loan Bank (FHLB) of Indianapolis and Federal Reserve stock. This restricted stock is carried at cost and periodically evaluated for impairment. Because this stock is viewed as a long-term investment, impairment is based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Servicing Rights: Servicing rights are recognized separately when they are acquired through sales of loans. When mortgage loans are sold, servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on third-party valuations that incorporate assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, ancillary income, prepayment speeds and default rates and losses. All classes of servicing assets are subsequently measured using the amortization method, which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Corporation later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with Other Service Charges and Fees on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is included in Other Service Charges and Fees on the income statement, is for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income. Servicing fees totaled $1.3 million , $1.3 million and $1.3 million for the years ended December 31, 2019 , 2018 and 2017 . Late fees and ancillary fees related to loan servicing are not material. Stock based compensation: Compensation cost is recognized for restricted stock awards and units issued to employees based on the fair value of these awards at the date of grant. Market price of the Corporation’s common stock at the date of grant is used for restricted stock awards. Compensation expense is recognized over the requisite service period. Transfers of Financial Assets: Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Corporation, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Bank-Owned Life Insurance: The Corporation has purchased life insurance policies on certain key executives. Bank-owned life insurance is recorded at its cash surrender value, or the amount that can be realized. Income on the investments in life insurance is included in other interest income. Goodwill and Other Intangible Assets: Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009 represents the future economic benefits arising from other assets acquired that are not individually identified and separately recognized. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Corporation has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consist of core deposit assets arising from the whole bank and branch acquisitions. They are initially measured at fair value and then are amortized on an accelerated basis over their estimated useful lives, which are 10 and 12 years, respectively. Long-Term Assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Benefit Plans: Pension expense is the net of service and interest cost, return on plan assets and amortization of gains and losses not immediately recognized. The amount contributed is determined by a formula as decided by the Board of Directors. Deferred compensation and supplemental retirement plan expense allocates the benefits over years of service. Employee Stock Ownership Plan: Shares of treasury stock are issued to the ESOP and compensation expense is recognized based upon the total market price of shares when contributed. Deferred Compensation Plan: Prior to 2011, a deferred compensation plan covered all directors. Under the plan, the Corporation pays each director, or their beneficiary, the amount of fees deferred plus interest over 10 years, beginning when the director achieves age 65 . A liability is accrued for the obligation under these plans. The expense incurred for the deferred compensation for each of the last three years was $109 thousand , $98 thousand and $95 thousand , resulting in a deferred compensation liability of $1.7 million at December 31, 2019 and $1.9 million at December 31, 2018 . There are no deferred compensation plans now in effect for directors. Incentive Plans: A long-term incentive plan established in 2000 provides for the payment of incentive rewards as a 15 -year annuity to all directors and certain key officers. That plan was in place through December 31, 2009, and compensation expense is recognized over the service period. Payments under the plan generally did not begin until the earlier of January 1, 2015, or the January 1 immediately following the year in which the participant reaches age 65 . There was no compensation expense related to this plan for 2019 , 2018 and 2017 . There is a liability of $7.6 million and $8.5 million as of year-end 2019 and 2018 . In 2011 the Corporation adopted the 2011 Short-term Incentive Plan and the 2011 Omnibus Equity Incentive Plan designed to reward key officers based on certain performance measures. The short-term portion of the plan is paid out within 75 days of year end and the long-term plan vests over a three year period and is paid out within 75 days of the end of each vesting period. The compensation expense related to the plans in 2019 , 2018 and 2017 was $1.9 million , $1.7 million and $1.6 million , respectively, and resulted in a liability of $1.0 million at December 31, 2019 and $899 thousand at December 31, 2018 . The Omnibus Equity Incentive Plan is a long term incentive plan that was designed to align the interests of participants with the interest of shareholders. Under the plan, awards may be made based on certain performance measures. The grants are made in restricted stock units that are subject to a vesting schedule. Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. The Corporation recognizes interest and/or penalties related to income tax matters in income tax expense. Loan Commitments and Related Financial Instruments: Financial instruments include credit instruments, such as commitments to make loans and standby letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. Earnings Per Share: Earnings per common share is net income divided by the weighted average number of common shares outstanding during the period. The Corporation does not have any potentially dilutive securities as the restricted stock awards are included in outstanding shares.. Earnings and dividends per share are restated for stock splits and dividends through the date of issue of the financial statements. Comprehensive Income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale and changes in the funded status of the retirement plans, net of taxes, which are also recognized as separate components of equity. Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount of range of loss can be reasonably estimated. Management does not believe there are currently such matters that will have a material effect on the financial statements. Dividend Restriction: Banking regulations require maintaining certain capital levels and may limit the dividends paid by the bank to the holding company or by the holding company to shareholders. Fair Value of Financial Instruments: Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or market conditions could significantly affect the estimates. Operating Segment: While the Corporation's chief decision-makers monitor the revenue streams of the various products and services, the operating results of significant segments are similar and operations are managed and financial performance is evaluated on a corporate-wide basis. Accordingly, all of the Corporation's financial service operations are considered by management to be aggregated in one reportable operating segment, which is banking. Accounting Pronouncements Adopted: In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases. The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The new standard was adopted by the Corporation on January 1, 2019. ASU 2016-02 provides for a modified retrospective transition approach requiring lessees to recognize and measure leases on the balance sheet at the beginning of either the earliest period presented or as of the beginning of the period of adoption. The Corporation elected to apply ASU 2016-02 as of the beginning of the period of adoption (January 1, 2019) and did not restate comparative periods. Adoption of ASU 2016-02 resulted in the recognition of lease liabilities totaling $7 million and the recognition of right-of- use assets totaling $7 million as of the date of adoption. Lease liabilities and right-of-use assets are reflected in other liabilities and other assets, respectively. The initial balance sheet gross up upon adoption was primarily related to operating leases of certain real estate properties. The Corporation has no finance leases or material subleases or leasing arrangements for which it is the lessor of property or equipment. The Corporation has elected to apply the package of practical expedients allowed by the new standard under which the Corporation need not reassess whether any expired or existing contracts are leases or contain leases, the Corporation need not reassess the lease classification for any expired or existing lease, and the Corporation need not reassess initial direct costs for any existing leases. Adoption of ASU 2016-02 did not materially change the Corporation’s recognition of lease expense. See Note 19 - Leases for additional disclosures related to leases. In July 2018, t

Fair Value Disclosures [Abstract]
FAIR VALUES OF FINANCIAL INSTRUMENTS	FAIR VALUES OF FINANCIAL INSTRUMENTS: Accounting guidance 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 1 prices such as 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 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 state and municipal securities. The fair value of the trust preferred securities is obtained from a third party provider without adjustment. Management obtains values from other pricing sources to validate the Standard & Poors pricing that they currently utilizes. 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 measurement. The fair value of derivatives is based on valuation models using observable market data as of the measurement date (Level 2 inputs).

Impaired loans disclosed in footnote 7, which are measured for impairment using the fair value of collateral, are valued at Level 3. They are carried at a fair value of $100 thousand , after a valuation allowance of $48 thousand at December 31, 2019 and at a fair value of $1.6 million , net of a valuation allowance of $0.7 million at December 31, 2018 . The impact to the provision for loan losses for the twelve months ended December 31, 2019 and December 31, 2018 was a $689 thousand decrease and a $112 thousand increase, respectively. Other real estate owned is valued at Level 3. Other real estate owned at December 31, 2019 with a value of $3.6 million was reduced $64 thousand for fair value adjustment. At December 31, 2019 other real estate owned was comprised of $3.5 million from commercial loans and $142 thousand from residential loans. Other real estate owned at December 31, 2018 with a value of $603 thousand was reduced $598 thousand for fair value adjustment. At December 31, 2018 other real estate owned was comprised of $171 thousand from commercial loans and $432 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 present quantitative information about recurring and non-recurring Level 3 fair value measurements at December 31, 2019 and 2018 . 2019 Fair Value Valuation Technique(s) Unobservable Input(s) Range State and municipal obligations $ 2,565 Discounted cash flow Discount rate 2.87%-4.44% Probability of default — % Other real estate $ 3,625 Sales comparison/income approach Discount rate for age of appraisal and market conditions 5.00%-20.00% Impaired Loans $ 100 Sales comparison/income approach Discount rate for age of appraisal and market conditions 0.00%-50.00% 2018 Fair Value Valuation Technique(s) Unobservable Input(s) Range State and municipal obligations $ 3,135 Discounted cash flow Discount rate 2.64%-4.80% Probability of default — % Other real estate $ 603 Sales comparison/income approach Discount rate for age of appraisal and market conditions 5.00%-20.00% Impaired Loans $ 1,639 Sales comparison/income approach Discount rate for age of appraisal and market conditions 0.00%-50.00% The following tables present impaired collateral dependent loans measured at fair value on a non-recurring basis by class of loans as of December 31, 2019 and 2018 .

Carrying amount is the estimated fair value for cash and due from banks, federal funds sold, accrued interest receivable and payable, demand deposits, short-term and certain other borrowings, and variable-rate loans or deposits that reprice frequently and fully. Security fair values are determined as previously described. It is not practicable to determine the fair value of restricted stock due to restrictions placed on their transferability. For fixed-rate 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 credit risk. Loan fair value estimates represent an exit price for 2019 and 2018. Fair values for impaired loans are estimated using discounted cash flow analysis or underlying collateral values. 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 unrealized losses on collateralized mortgage obligations, all mortgage-backed securities and state and municipal obligations represent negative adjustments to fair value relative to the rate of interest paid on the securities and not losses related to the creditworthiness of the issuer. Gross unrealized losses on investment securities were $1.8 million as of December 31, 2019 and $15.2 million as of December 31, 2018 . Management does not intend to sell and it is not more likely than not that management would be required to sell the securities prior to their anticipated recovery. Management believes the value will recover as the securities approach maturity or market rates change. Management evaluates securities for other-than-temporary impairment ("OTTI") at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. 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. In determining OTTI under the FASB ASC-320 model, management considers many factors, including: (1)the length of time and the extent to which the fair value has been less than cost, (2)the financial condition and near-term prospects of the issuer, (3) whether the fair value decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the security or more likely than not will be required to sell the security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. The second segment of the portfolio uses the OTTI guidance provided by FASB ASC-325 that is specific to purchase beneficial interests that, on the purchase date, were rated below AA. Under the FASB ASC-325 model, the Corporation compares the present value of the remaining cash flows as estimated at the preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows. 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. In prior years, a significant portion of the total unrealized losses relates to collateralized debt obligations that were separately evaluated under FASB ASC 325-40, Beneficial Interests in Securitized Financial Assets. Based upon qualitative considerations, such as a downgrade in credit rating or further defaults of underlying issuers during the year, and an analysis of expected cash flows, we determined that three CDOs included in collateralized debt obligations were other-than-temporarily impaired. One of the CDO's was called in first quarter 2017. A second was called in second quarter 2018. The remaining CDO has a contractual balance of $3.7 million at December 31, 2019 which has been reduced to $3.6 million by $750 thousand of interest payments received, $3.0 million of cumulative OTTI charges recorded through earnings to date and increased by $3.6 million recorded in other comprehensive income. These securities are collateralized by trust preferred securities issued primarily by bank holding companies, but certain pools do include a limited number of insurance companies. The Corporation uses the OTTI evaluation model to compare the present value of expected cash flows to the previous estimate to determine if there are adverse changes in cash flows during the year. The OTTI model considers the structure and term of the CDO and the financial condition of the underlying issuers. Specifically, the model details interest rates, principal balances of note classes and underlying issuers, the timing and amount of interest and principal payments of the underlying issuers, and the allocation of the payments to the note classes. Cash flows are projected using a forward rate LIBOR curve, as these CDOs are variable-rate instruments. An average rate is then computed using this same forward rate curve to determine an appropriate discount rate ( 3 month LIBOR plus margin ranging from 160 to 180 basis points). The current estimate of expected cash flows is based on the most recent trustee reports and any other relevant market information, including announcements of interest payment deferrals or defaults of underlying trust preferred securities. Assumptions used in the model include expected future default rates and prepayments. We assume no recoveries on defaults and treat all interest payment deferrals as defaults. In addition we use the model to “stress” each CDO, or make assumptions more severe than expected activity, to determine the degree to which assumptions could deteriorate before the CDO could no longer fully support repayment of the Corporation’s note class. In the current year management determined there was no OTTI. There was no OTTI recorded in 2019 or 2018. Collateralized debt obligations include one additional investment in a CDO consisting of pooled trust preferred securities in which the issuers are primarily banks. This CDO was paid in full in 2015. In the first quarter of 2017 a CDO with no remaining book value was called with the bank receiving $3.1 million , which is included in other non-interest income on the consolidated statements of income and comprehensive income. In the second quarter of 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.

At December 31, 2019 and 2018 , loans held for sale were $5.8 million and $3.2 million , respectively, and are included in the totals above. In the normal course of business, the Corporation’s subsidiary banks make loans to directors and executive officers and to their associates. In 2019 , the aggregate dollar amount of these loans to directors and executive officers who held office amounted to $53.0 million at the beginning of the year. During 2019 , advances of $78.2 million , repayments of $58.1 million , and additions for new directors of $16.4 million were made with respect to related party loans for an aggregate dollar amount outstanding of $89.5 million at December 31, 2019 . Loans serviced for others, which are not reported as assets, total $477.0 million and $473.8 million at year-end 2019 and 2018 . Custodial escrow balances maintained in connection with serviced loans were $3.1 million and $3.0 million at year-end 2019 and 2018 . Activity for capitalized mortgage servicing rights (included in other assets) was as follows: December 31, (Dollar amounts in thousands) 2019 2018 2017 Servicing rights: Beginning of year $ 1,431 $ 1,434 $ 1,549 Additions 579 513 477 Amortized to expense (575 ) (516 ) (592 ) End of year $ 1,435 $ 1,431 $ 1,434 Third party valuations are conducted periodically for mortgage servicing rights. Based on these valuations, fair values were approximately $2.7 million and $2.3 million at year end 2019 and 2018 . There was no valuation allowance in 2019 or 2018 . Fair value for 2019 was determined using a discount rate of 12.5% , prepayment speeds ranging from 118% to 263% , depending on the stratification of the specific right. Fair value at year end 2018 was determined using a discount rate of 13% , prepayment speeds ranging from 88% to 189% , depending on the stratification of the specific right. Mortgage servicing rights are amortized over 8 years, the expected life of the sold loans.

ACQUISITIONS AND FDIC INDEMNIFICATION ASSET	ACQUISITIONS, DIVESTITURES AND FDIC INDEMNIFICATION ASSET: On July 27, 2019, the Corporation completed its acquisition of HopFed Bancorp, Inc. and its banking subsidiary, Heritage Bank. Therefore, the results of HopFed have been included in the results of operations beginning on July 27, 2019. Pursuant to the terms of the merger agreement, each issued and outstanding share of HopFed common stock, $0.01 par value per share, was converted into the right to receive, at the stockholder's election, either (or a combination of) 0.444 shares of Corporation common stock, without par value, or $21.00 in cash, subject to proration provisions specified in the merger agreement that provide for an aggregate split of 50% of shares of HopFed Common Stock being exchanged for Corporation Common Stock and 50% for cash, with cash to be paid in lieu of fractional shares. Each outstanding share of Corporation common stock remained outstanding and was unaffected by the merger. Acquisition-related costs of $3.3 million are included in the Corporation's income statement for the year ended December 31, 2019. Goodwill of $44.2 million arising from the acquisition consisted largely of synergies and the cost savings resulting from the combining of the operations of the companies. The goodwill is not deductible for income tax purposes as the transaction was accounted for as a tax-free exchange. The following table summarizes the consideration paid and the amounts of the assets acquired and liabilities assumed recognized at the acquisition date. (Dollar amounts in thousands) As Initially Reported Measurement Period Adjustments As Adjusted Consideration Cash consideration $ 67,348 $ — $ 67,348 Stock consideration 61,878 — 61,878 Fair value of total consideration transferred $ 129,226 $ — $ 129,226 Assets acquired Cash $ 34,518 $ 34,518 Investment securities available-for-sale 174,851 174,851 Bank owned life insurance 10,693 10,693 Federal Home Loan Bank stock 4,428 4,428 Loans 657,179 1,719 658,898 Premises and equipment 25,316 (6,494 ) 18,822 Core deposit intangibles 10,369 10,369 Other real estate owned 3,364 3,364 Other assets 6,596 1,600 8,196 Total assets acquired 927,314 (3,175 ) 924,139 Liabilities assumed Deposits 735,526 735,526 FHLB advances 20,775 20,775 Other borrowings 75,783 75,783 Other liabilities 7,066 7,066 Total liabilities assumed 839,150 — 839,150 Net identifiable assets 88,164 (3,175 ) 84,989 Goodwill $ 41,062 $ 3,175 $ 44,237 The fair value of net assets acquired includes fair value adjustments to certain receivables that were not considered impaired as of the acquisition date. The fair value adjustments were determined using discounted contractual cash flows. However, the Corporation believes that all contractual cash flows related to these financial instruments will be collected. As such, these receivables were not considered impaired at the acquisition date and were not subject to guidance relating to purchase credit impaired loans, which have shown evidence of credit deterioration since origination. The following table presents supplemental pro forma information as if the acquisition had occurred at the beginning of 2018. The unaudited pro forma information includes adjustments for interest income on loans and securities acquired, interest expense on deposits acquired, and the related income tax effects. The pro forma financial information is not necessarily indicative of the results of operations that would have occurred had the transactions been effected on the assumed dates.

Under the loss-sharing agreement (“LSA”), the Bank shared in the losses on assets covered under the agreement (referred to as covered assets). On losses up to $29 million , the FDIC agreed to reimburse the Bank for 80% of the losses. On losses exceeding $29 million , the FDIC agreed to reimburse the Bank for 95% of the losses. The loss-sharing agreement was subject to following servicing procedures as specified in the agreement with the FDIC. Loans acquired that were subject to the loss-sharing agreement with the FDIC were referred to as covered loans for disclosure purposes. Since the acquisition date the Bank has been reimbursed $24.3 million for losses and carrying expenses. The balance of the loans that were covered by the loss share agreement excluding AS 310-30 loans at December 31, 2018 totaled $3.2 million . The agreement expired on July 2, 2019. 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 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 less than $100 thousand or are included in groups of homogeneous loans. As of December 31, 2019 and 2018 , and based on the most recent analysis performed, the risk category of loans by class of loans is as follows: December 31, 2019 Special (Dollar amounts in thousands) Pass Mention Substandard Doubtful Not Rated Total Commercial Commercial & Industrial $ 549,341 $ 19,253 $ 26,349 $ 5 $ 2,761 $ 597,709 Farmland 119,858 8,673 8,644 — 100 137,275 Non Farm, Non Residential 381,404 4,424 12,269 — 3,678 401,775 Agriculture 127,144 4,507 27,490 — 985 160,126 All Other Commercial 283,266 3,141 1,120 — 35 287,562 Residential First Liens 174,338 926 4,382 — 204,266 383,912 Home Equity 18,417 — 134 11 52,280 70,842 Junior Liens 2,839 64 178 76 51,817 54,974 Multifamily 146,497 112 1,315 — 19 147,943 All Other Residential 12,624 — 205 — 11,577 24,406 Consumer Motor Vehicle 2,880 — 538 — 350,780 354,198 All Other Consumer 3,155 — 38 — 28,615 31,808 TOTAL $ 1,821,763 $ 41,100 $ 82,662 $ 92 $ 706,913 $ 2,652,530 December 31, 2018 Special (Dollar amounts in thousands) Pass Mention Substandard Doubtful Not Rated Total Commercial Commercial & Industrial $ 472,008 $ 20,600 $ 18,374 $ — $ 7,428 $ 518,410 Farmland 90,367 7,587 7,783 — 19 105,756 Non Farm, Non Residential 170,757 5,442 10,439 — 1,695 188,333 Agriculture 118,952 10,010 16,637 — 457 146,056 All Other Commercial 198,302 43 6,777 — 2,675 207,797 Residential First Liens 43,915 1,043 3,504 — 187,685 236,147 Home Equity 963 — 148 — 38,471 39,582 Junior Liens 1,983 74 224 76 47,060 49,417 Multifamily 109,361 — — — 17 109,378 All Other Residential — — 15 — 9,131 9,146 Consumer Motor Vehicle — — 627 — 312,863 313,490 All Other Consumer — — 34 — 27,517 27,551 TOTAL $ 1,206,608 $ 44,799 $ 64,562 $ 76 $ 635,018 $ 1,951,063

The Corporation enters into sales of securities under agreements to repurchase. 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. Securities are pledged to cover these liabilities, which are not covered by federal deposit insurance. The Corporation maintains possession of and control over these securities.

Risks and Uncertainties [Abstract]
FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK	FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK: The Corporation is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include conditional commitments and commercial letters of credit. The financial instruments involve to varying degrees, elements of credit and interest rate risk in excess of amounts recognized in the financial statements. The Corporation's maximum exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to make loans is limited generally by the contractual amount of those instruments. The Corporation follows the same credit policy to make such commitments as is followed for those loans recorded in the consolidated financial statements. Commitment and contingent liabilities are summarized as follows at December 31: (Dollar amounts in thousands) 2019 2018 Home Equity $ 87,327 $ 57,341 Commercial Operating Lines 358,561 285,524 Other Commitments 105,872 81,593 TOTAL $ 551,760 $ 424,458 Commercial letters of credit $ 3,851 $ 4,673 The majority of commercial operating lines and home equity lines are variable rate, while the majority of other commitments to fund loans are fixed rate. Fixed rate commitments had a range of interest rates from 4.25% to 7.25% in 2019 . In 2018 this range of rates was from 4.50% to 7.75% . Since many commitments to make loans expire without being used, these amounts do not necessarily represent future cash commitments. Collateral obtained upon exercise of the commitment is determined using management's credit evaluation of the borrower, and may include accounts receivable, inventory, property, land and other items. The approximate duration of these commitments is generally one year or less. Derivatives: The Corporation enters into derivative instruments for the benefit of its customers. At the inception of a derivative contract, the Corporation designates the derivative as an instrument with no hedging designation ("standalone derivative"). Changes in the fair value of derivatives are reported currently in earnings as non-interest income. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income. First Financial Bank offers clients the ability on certain transactions to enter into interest rate swaps. Typically, these are pay fixed, receive floating swaps used in conjunction with commercial loans. These derivative contracts do not qualify for hedge accounting. The Bank hedges the exposure to these contracts by entering into offsetting contracts with substantially matching terms. The notional amount of these interest rate swaps was $26.2 million and $19.0 million at December 31, 2019 and 2018 . The fair value of these contracts combined was zero, as gains offset losses. The gross gain and loss associated with these interest rate swaps was $0.8 million and $0.1 million at December 31, 2019 and 2018 .

Retirement Benefits [Abstract]
RETIREMENT PLANS	RETIREMENT PLANS: Employees of the Corporation are covered by a retirement program that consists of a defined benefit plan and an employee stock ownership plan (ESOP). Plan assets consist primarily of the Corporation's stock and obligations of U.S. Government agencies. Benefits under the defined benefit plan are actuarially determined based on an employee's service and compensation, as defined, and funded as necessary. This plan was frozen for the majority of employees as of December 31, 2012.Those employees will be eligible to participate in a 401K plan that the Corporation can contribute a discretionary match of the pay contributed by the employee. In addition the ESOP plan will continue in place for all employees. Assets in the ESOP are considered in calculating the funding to the defined benefit plan required to provide such benefits. Any shortfall of benefits under the ESOP are to be provided by the defined benefit plan. The ESOP may provide benefits beyond those determined under the defined benefit plan. Contributions to the ESOP are determined by the Corporation's Board of Directors. The Corporation made contributions to the defined benefit plan of $1.77 million , $2.26 million and $2.55 million in 2019 , 2018 and 2017 . The Corporation contributed $1.25 million , $1.09 million and $1.06 million to the ESOP in 2019 , 2018 and 2017 . There were contributions of $926 thousand , $735 thousand and $676 thousand to the ESOP for employees no longer participating in the defined benefit plan in 2019 , 2018 and 2017 respectively. The Corporation uses a measurement date of December 31. Net periodic benefit cost and other amounts recognized in other comprehensive income included the following components: (Dollar amounts in thousands) 2019 2018 2017 Service cost - benefits earned $ 1,218 $ 1,388 $ 1,432 Interest cost on projected benefit obligation 3,465 3,194 3,621 Expected return on plan assets (3,585 ) (3,962 ) (3,940 ) Net amortization and deferral 1,558 1,448 1,205 Net periodic pension cost 2,656 2,068 2,318 Net loss (gain) during the period 6,362 (1,192 ) 5,366 Amortization of prior service cost (1 ) (1 ) (1 ) Amortization of unrecognized gain (loss) (1,558 ) (1,447 ) (1,204 ) Total recognized in other comprehensive (income) loss 4,803 (2,640 ) 4,161 Total recognized net periodic pension cost and other comprehensive income $ 7,459 $ (572 ) $ 6,479 The estimated net loss and prior service costs (credits) for the defined benefit pension plan that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the next fiscal year are $2.0 million and $1 thousand . The information below sets forth the change in projected benefit obligation, reconciliation of plan assets, and the funded status of the Corporation's retirement program. Actuarial present value of benefits is based on service to date and present pay levels. (Dollar amounts in thousands) 2019 2018 Change in benefit obligation: Benefit obligation at January 1 $ 87,796 $ 98,096 Service cost 1,218 1,388 Interest cost 3,465 3,194 Actuarial (gain) loss 14,233 (10,618 ) Benefits paid (3,921 ) (4,264 ) Benefit obligation at December 31 102,791 87,796 Reconciliation of fair value of plan assets: Fair value of plan assets at January 1 64,335 71,449 Actual return on plan assets 11,456 (5,464 ) Employer contributions 2,092 2,614 Benefits paid (3,921 ) (4,264 ) Fair value of plan assets at December 31 73,962 64,335 Funded status at December 31 (plan assets less benefit obligation) $ (28,829 ) $ (23,461 ) Amounts recognized in accumulated other comprehensive income at December 31, 2019 and 2018 consist of: (Dollar amounts in thousands) 2019 2018 Net loss (gain) $ 27,786 $ 22,982 Prior service cost (credit) 2 2 $ 27,788 $ 22,984 The accumulated benefit obligation for the defined benefit pension plan was $98.4 million and $83.9 million at year-end 2019 and 2018 . Principal assumptions used to determine pension benefit obligation at year end: 2019 2018 Discount rate 3.22 % 4.22 % Rate of increase in compensation levels 3.00 3.00 Principal assumptions used to determine net periodic pension cost: 2019 2018 Discount rate 4.22 % 3.60 % Rate of increase in compensation levels 3.00 3.00 Expected long-term rate of return on plan assets 6.00 6.00 The expected long-term rate of return was estimated using market benchmarks for equities and bonds applied to the plan's target asset allocation. Management estimated the rate by which plan assets would perform based on historical experience as adjusted for changes in asset allocations and expectations for future return on equities as compared to past periods. Plan Assets — The Corporation's pension plan weighted-average asset allocation for the years 2019 and 2018 by asset category are as follows: Pension Plan Target Allocation ESOP Target Allocation Pension Percentage of Plan Assets at December 31, ESOP Percentage of Plan Assets at December 31, ASSET CATEGORY 2019 2019 2019 2018 2019 2018 Equity securities 25-75% 95-99% 63 % 65 % 98 % 99 % Debt securities 0-50% 0-0% 33 % 31 % — % — % Other 0-20% 0-5% 4 % 4 % 2 % 1 % TOTAL 100 % 100 % 100 % 100 % Fair Value of Plan Assets — Fair value is the exchange price that would be received for an asset in the principal or most advantageous market for the asset in an orderly transaction between market participants on the measurement date. It also 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 Corporation used the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Equity, Debt, Investment Funds and Other Securities — The fair values for investment securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). The fair value of the plan assets at December 31, 2019 and 2018 , by asset category, is as follows: Fair Value Measurements at December 31, 2019 Using: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Observable Inputs (Dollar amounts in thousands) Total (Level 1) (Level 2) (Level 3) Plan assets Equity securities $ 51,334 $ 51,334 $ — $ — Debt securities 13,104 — 13,104 — Investment Funds 9,524 9,524 — — Total plan assets $ 73,962 $ 60,858 $ 13,104 $ — Fair Value Measurements at December 31, 2018 Using: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Observable Inputs (Dollar amounts in thousands) Total (Level 1) (Level 2) (Level 3) Plan assets Equity securities $ 43,931 $ 43,931 $ — $ — Debt securities 10,652 — 10,652 — Investment Funds 9,752 9,752 — — Total plan assets $ 64,335 $ 53,683 $ 10,652 $ — The investment objective for the retirement program is to maximize total return without exposure to undue risk. Asset allocation favors equities. This target includes the Corporation's ESOP, which is fully invested in corporate stock. Other investment allocations include fixed income securities and cash. The plan is prohibited from investing in the following: private placement equity and debt transactions; letter stock and uncovered options; short-sale margin transactions and other specialized investment activity; and fixed income or interest rate futures. All other investments not prohibited by the plan are permitted. Equity securities in the defined benefit plan include First Financial Corporation common stock in the amount of $19.8 million ( 27 percent of total plan assets) and $18.0 million ( 28 percent of total plan assets) at December 31, 2019 and 2018 , respectively. In addition the ESOP for non plan participants holds an estimated $5.1 million and $ 3.8 million of First Financial Corporation stock at December 31, 2019 and December 31, 2018 respectively. Other equity securities are predominantly stocks in large cap U.S. companies.

REGULATORY MATTERS_

REGULATORY MATTERS:	12 Months Ended

Banking and Thrift [Abstract]
REGULATORY MATTERS	REGULATORY MATTERS: The Corporation and its bank affiliates are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory—and possibly additional discretionary—actions by regulators that, if undertaken, could have a direct material effect on the Corporation's financial statements. Further, the Corporation's primary source of funds to pay dividends to shareholders is dividends from its subsidiary banks and compliance with these capital requirements can affect the ability of the Corporation and its banking affiliates to pay dividends. At December 31, 2019 , approximately $26.7 million of undistributed earnings of the subsidiary banks, included in consolidated retained earnings, were available for distribution to the Corporation without regulatory approval. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation and Banks must meet specific capital guidelines that involve quantitative measures of the Corporation's assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Corporation's and Banks' capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Corporation and Banks to maintain minimum amounts and ratios of Total, Common equity tier I capital and Tier I Capital to risk-weighted assets, and of Tier I Capital to average assets. The final rules implementing Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel lll rules) became effective for the Corporation on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Under the Basel lll rules, the Corporation must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer is being phased in from 0.0% for 2015 to 2.50% by 2019. The capital conservation buffer for 2018 and 2017 is 1.875% and 1.25%, respectively. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes, as of December 31, 2019 and 2018 , that the Corporation meets all capital adequacy requirements to which it is subject. As of December 31, 2019 , the most recent notification from the respective regulatory agencies categorized the subsidiary banks as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the banks must maintain minimum total risk-based, Common equity tier I capital, Tier I risk-based and Tier I leverage ratios as set forth in the table.

BUSINESS AND SIGNIFICANT ACCO_2

BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES: (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Share Based Compensation [Policy Text Block]	Stock based compensation: Compensation cost is recognized for restricted stock awards and units issued to employees based on the fair value of these awards at the date of grant. Market price of the Corporation’s common stock at the date of grant is used for restricted stock awards. Compensation expense is recognized over the requisite service period.
Organization	Organization: The consolidated financial statements of First Financial Corporation and its subsidiaries (the Corporation) include the parent company and its wholly-owned subsidiaries, First Financial Bank, N.A. headquartered in Vigo County, Indiana, The Morris Plan Company of Terre Haute (Morris Plan), First Chanticleer Corporation, a property rental entity headquartered in Terre Haute, Indiana, and FFB Risk Management Co., Inc., a captive insurance subsidiary headquartered in Las Vegas, Nevada. Inter-company transactions and balances have been eliminated.
Use of Estimates	Use of Estimates: To prepare financial statements in conformity with U.S. generally accepted accounting principles, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ.
Cash Flows	Cash Flows : Cash and cash equivalents include cash and demand deposits with other financial institutions. Cash flows are reported for customer loan and deposit transactions and short-term borrowings.
Securities	Securities : The Corporation classifies all securities as "available for sale." Securities are classified as available for sale when they might be sold before maturity. Securities available for sale are carried at fair value with unrealized holdings gains and losses, net of taxes, reported in other comprehensive income within shareholders' equity. Interest income includes amortization of purchase premium or discount. Premiums and discounts are amortized on the level yield method without anticipating prepayments. Mortgage-backed securities are amortized over the expected life. Realized gains and losses on sales are based on the amortized cost of the security sold. Management evaluates securities for other-than temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation.
Loans	Loans: Loans that management has the intent and ability to hold for the foreseeable future until maturity or pay-off are reported at the principal balance outstanding, net of unearned interest, purchase premiums and discounts, deferred loan fees and costs, and allowance for loan losses. Loans held for sale are reported at the lower of cost or fair value, on an aggregate basis. Interest income is accrued on the unpaid principal balance and includes amortization of net deferred loan fees and costs over the loan term without anticipating prepayments. The recorded investment in loans includes accrued interest receivable and net deferred loan fees and costs. Interest income is not reported when full loan repayment is in doubt, typically when the loan is impaired or payments are significantly past due. Past-due status is based on the contractual terms of the loan. All interest accrued but not received for loans placed on non-accrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. In all cases, loans are placed on non-accrual or charged-off if collection of principal or interest is considered doubtful. The above policies are consistent for all segments of loans.
Certain Purchased Loans	Certain Purchased Loans: The Corporation purchases individual loans and groups of loans, some of which have shown evidence of credit deterioration since origination. These purchased loans are recorded at the amount paid, such that there is no carryover of the seller's allowance for loan losses. After acquisition, losses are recognized by an increase in the allowance for loan losses. Such purchased loans are accounted for individually. The Corporation estimates the amount and timing of expected cash flows for each purchased loan, and the expected cash flows in excess of amount paid are recorded as interest income over the remaining life of the loan (accretable yield). The excess of the loan's contractual principal and interest over expected cash flows is not recorded (nonaccretable difference). Over the life of the loan, expected cash flows continue to be estimated. If the present value of expected cash flows is less than the carrying amount, a provision for loan loss is recorded. If the present value of expected cash flows is greater than the carrying amount, it is recognized as part of future interest income.
Concentration of Credit Risk	Concentration of Credit Risk: Most of the Corporation's business activity is with customers located within west central Indiana and east central Illinois. Therefore, the Corporation's exposure to credit risk is significantly affected by changes in the economy of this area. A major economic downturn in this area would have a negative effect on the Corporation's loan portfolio.
Allowance for Loan Losses	Allowance for Loan Losses: The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management's judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers non-classified loans as well as non-impaired classified loans and is based on historical loss experience adjusted for current factors. A loan is impaired when full payment under the loan terms is not expected. Loans for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Impairment is evaluated in total for smaller-balance loans of similar nature such as residential mortgages and consumer loans, and on an individual basis for other loans. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows, using the loan's existing rate, or at the fair value of collateral if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment and, accordingly, they are not separately identified for impairment disclosures. The general component covers non-classified loans as well as non-impaired classified loans and is based on historical loss experience adjusted for current factors. The historical loss experience is based on the actual loss history experienced over the most recent four years. This actual loss experience is supplemented with other current factors based on the risks present for each portfolio segment. These current factors include consideration of the following: levels of and trends in delinquent, classified, and impaired loans; levels of and trends in charge-offs and recoveries; national and local economic trends and conditions; changes in lending policies and procedures; trends in volume and terms of loans; experience, ability, and depth of lending management and other relevant staff; credit concentrations; value of underlying collateral for collateral dependent loans; and other external factors such as competition and legal and regulatory requirements. The following portfolio segments have been identified: commercial loans, residential loans and consumer loans. A characteristic of the commercial loan segment is that the loans are for business purchases. A characteristic of the residential loan segment is that the loans are secured by residential properties. A characteristic of the consumer loan segment is that the loans are for automobiles and other consumer purchases. Commercial loans are generally well secured, which mitigates the risk of loss and has contributed to the low historical loss rate. However, concentrations in commercial real estate, along with the potential impact of rising interest rates to commercial real estate, raises the risk of loss on commercial loans. For these reasons, commercial loans have the highest adjustment to the historical loss rate. Continued weakness in local economic conditions along with declining auto values resulted in consumer loans having the next highest level of adjustment to the historical loss rate. The residential loan portfolio segment had the lowest level of adjustment to the historical loss rate. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Corporation determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses.
FDIC Indemnification Asset
Foreclosed Assets	Foreclosed Assets: Assets acquired through or instead of loan foreclosures are initially recorded at fair value less estimated selling costs when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or similar legal agreement. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines, a valuation allowance is recorded through expense. Costs after acquisition are expensed.
Premises and Equipment	Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed over the useful lives of the assets, which range from 3 to 5 years for furniture and equipment and 33 to 39 years for buildings and leasehold improvements.
Restricted Stock	Restricted Stock: Restricted stock includes Federal Home Loan Bank (FHLB) of Indianapolis and Federal Reserve stock. This restricted stock is carried at cost and periodically evaluated for impairment. Because this stock is viewed as a long-term investment, impairment is based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Servicing Rights	Servicing Rights: Servicing rights are recognized separately when they are acquired through sales of loans. When mortgage loans are sold, servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on third-party valuations that incorporate assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, ancillary income, prepayment speeds and default rates and losses. All classes of servicing assets are subsequently measured using the amortization method, which requires servicing rights to be amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into groupings based on predominant risk characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Corporation later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. Changes in valuation allowances are reported with Other Service Charges and Fees on the income statement. The fair values of servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses. Servicing fee income, which is included in Other Service Charges and Fees on the income statement, is for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income.
Transfers of Financial Assets	Transfers of Financial Assets: Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Corporation, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Life Insurance Corporate Or Bank Owned Policy [Text Block]	Bank-Owned Life Insurance: The Corporation has purchased life insurance policies on certain key executives. Bank-owned life insurance is recorded at its cash surrender value, or the amount that can be realized. Income on the investments in life insurance is included in other interest income.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009 represents the future economic benefits arising from other assets acquired that are not individually identified and separately recognized. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Corporation has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consist of core deposit assets arising from the whole bank and branch acquisitions. They are initially measured at fair value and then are amortized on an accelerated basis over their estimated useful lives, which are 10 and 12 years, respectively.
Long-Term Assets	Long-Term Assets: Premises and equipment and other long-term assets are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Benefit Plans	Benefit Plans: Pension expense is the net of service and interest cost, return on plan assets and amortization of gains and losses not immediately recognized. The amount contributed is determined by a formula as decided by the Board of Directors. Deferred compensation and supplemental retirement plan expense allocates the benefits over years of service.
Employee Stock Ownership Plan	Employee Stock Ownership Plan: Shares of treasury stock are issued to the ESOP and compensation expense is recognized based upon the total market price of shares when contributed.
Deferred Compensation Plan	Deferred Compensation Plan: Prior to 2011, a deferred compensation plan covered all directors. Under the plan, the Corporation pays each director, or their beneficiary, the amount of fees deferred plus interest over 10 years, beginning when the director achieves age 65 . A liability is accrued for the obligation under these plans.
Incentive Plans	Incentive Plans: A long-term incentive plan established in 2000 provides for the payment of incentive rewards as a 15 -year annuity to all directors and certain key officers. That plan was in place through December 31, 2009, and compensation expense is recognized over the service period. Payments under the plan generally did not begin until the earlier of January 1, 2015, or the January 1 immediately following the year in which the participant reaches age 65 . There was no compensation expense related to this plan for 2019 , 2018 and 2017 . There is a liability of $7.6 million and $8.5 million as of year-end 2019 and 2018 . In 2011 the Corporation adopted the 2011 Short-term Incentive Plan and the 2011 Omnibus Equity Incentive Plan designed to reward key officers based on certain performance measures.
Income Taxes	Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the "more likely than not" test, no tax benefit is recorded. The Corporation recognizes interest and/or penalties related to income tax matters in income tax expense.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments: Financial instruments include credit instruments, such as commitments to make loans and standby letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Earnings Per Share	Earnings Per Share: Earnings per common share is net income divided by the weighted average number of common shares outstanding during the period. The Corporation does not have any potentially dilutive securities as the restricted stock awards are included in outstanding shares.. Earnings and dividends per share are restated for stock splits and dividends through the date of issue of the financial statements.
Comprehensive Income	Comprehensive Income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale and changes in the funded status of the retirement plans, net of taxes, which are also recognized as separate components of equity.
Loss Contingencies	Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount of range of loss can be reasonably estimated. Management does not believe there are currently such matters that will have a material effect on the financial statements.
Dividend Restriction	Dividend Restriction: Banking regulations require maintaining certain capital levels and may limit the dividends paid by the bank to the holding company or by the holding company to shareholders.
Fair Value of Financial Instruments	Fair Value of Financial Instruments: Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or market conditions could significantly affect the estimates.
Operating Segment	Operating Segment: While the Corporation's chief decision-makers monitor the revenue streams of the various products and services, the operating results of significant segments are similar and operations are managed and financial performance is evaluated on a corporate-wide basis. Accordingly, all of the Corporation's financial service operations are considered by management to be aggregated in one reportable operating segment, which is banking.
Adoption of New Accounting Standards	: 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. The Corporation formed a cross-functional internal management committee and engaged a third party vendor to assist with the transition to the guidance set forth in this update. The new allowance model implemented by the Corporation estimates credit losses over the expected life of the portfolio and includes a qualitative framework to account for the drivers of losses that are not captured by the quantitative model. The results continue to be utilized to refine our models and estimation techniques. Documentation of new methodologies and internal controls that will be implemented as part of CECL as well as model validation is also being finalized. While the committee continues to analyze and modify calculations, the Corporation currently expects the adoption of ASU 2016-13 will result in an increase in allowance for loan losses amount at January 1, 2020 in the range of $15 million to $25 million. The allowance for credit losses also increased due to the requirement to record an allowance on acquired loan portfolios, previously recorded at fair value. Once finalized, the cumulative effect adjustment, as a result of the adoption of this guidance, will be recorded, net of tax, as an adjustment to retained earnings effective January 1, 2020. This estimate is subject to change as key assumptions are refined and model validations are finalized. 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.
