Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The Consolidated Financial Statements of First Financial Bancorp., a bank holding company, principally serving Ohio, Indiana and Kentucky, include the accounts and operations of First Financial and its wholly-owned subsidiary, First Financial Bank, N.A. All significant intercompany transactions and accounts have been eliminated in consolidation. Certain reclassifications of prior periods' amounts, including covered loans and the related allowance for loan and lease losses in the Consolidated Balance Sheets have been made to conform to current year presentation. Such reclassifications had no effect on net earnings. Effective October 1, 2014, the five-year loss sharing coverage period for non-single family assets expired and the majority of the Company’s formerly covered assets were no longer subject to FDIC loss sharing protection. As a result of this expiration, and the insignificant balance of assets that remain subject to FDIC loss sharing protection through October 1, 2019 relative to the Company’s total assets, all covered loans and the related allowance for loan and lease losses, as well as provision for covered loan and lease losses, have been reclassified in the Consolidated Financial Statements, and all credit quality metrics have been updated to include covered and formerly covered assets. The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. These estimates, assumptions and judgments are inherently subjective and may be susceptible to significant change. Actual realized amounts could differ materially from these estimates. These interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and serve to update the Form 10-K for the year ended December 31, 2014 . These interim financial statements may not include all information and notes necessary to constitute a complete set of financial statements under GAAP applicable to annual periods and it is suggested that these interim statements be read in conjunction with the Form 10-K. Management believes these unaudited consolidated financial statements reflect all adjustments of a normal recurring nature which are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. The Consolidated Balance Sheet as of December 31, 2014 has been derived from the audited financial statements in the Company’s 2014 Form 10-K.

RECENTLY ADOPTED AND ISSUED ACC

RECENTLY ADOPTED AND ISSUED ACCOUNTING STANDARDS	6 Months Ended
	Jun. 30, 2015
Recently Adopted and Issued Accounting Standards [Abstract]
Recently Adopted and Issued Accounting Standards Disclosure [Text Block]	RECENTLY ADOPTED AND ISSUED ACCOUNTING STANDARDS In January 2014, the FASB issued an update (ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects) that permits First Financial to make an accounting policy election to account for its investments in qualified affordable housing projects using a proportional amortization method if certain conditions are met. Under the proportional amortization method, First Financial would amortize the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognize the net investment performance in the income statement as a component of income tax expense. The amended guidance requires disclosure of the nature of First Financial’s investments in qualified affordable housing projects, and the effect of the measurement of the investments in qualified affordable housing projects and the related tax credits on First Financial’s financial position and results of operation. The provisions of this update became effective for the interim reporting period ended March 31, 2015. First Financial made the election to adopt the proportional amortization method during the first quarter 2015 and had $24.4 million of affordable housing commitments as of June 30, 2015 . This update did not have a material impact on the Company's Consolidated Financial Statements. In January 2014, the FASB issued an update (ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure) which clarifies when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be de-recognized and the real estate property recognized . The provisions of this update became effective for the interim reporting period ended March 31, 2015. This update did not have a material impact on the Company's Consolidated Financial Statements. In April 2014, the FASB issued an update (ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity) which redefines what constitutes a discontinued operation. Under the revised standard, a discontinued operation is a component of an entity or group of components that has been disposed of by sale, disposed of other than by sale or is classified as held for sale, that represents a strategic shift that has or will have a major effect on an entity’s operations and financial results or an acquired business or nonprofit activity that is classified as held for sale on the date of the acquisition. A strategic shift that has or will have a major effect on an entity’s operations and financial results could include the disposal of a major line of business, a major geographic area, a major equity method investment or other major parts of an entity. The new guidance eliminates the criteria prohibiting an entity from reporting a discontinued operation if it has certain continuing cash flows or involvement with the component after the disposal and requires additional disclosures for discontinued operations and new disclosures for individually material disposal transactions that do not meet the definition of a discontinued operation. The provisions of this update became effective for the interim reporting period ended March 31, 2015. This update did not have a material impact on the Company's Consolidated Financial Statements. In May 2014, the FASB issued an update (ASU 2014-09, Revenue from Contracts with Customers) which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. Under the revised standard, an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU applies to all contracts with customers except those that are within the scope of other topics in the FASB Accounting Standards Codification. Certain of the ASU’s provisions also apply to transfers of nonfinancial assets, including in-substance nonfinancial assets that are not an output of an entity’s ordinary activities, such as sales of property, plant, and equipment; real estate; or intangible assets. The ASU also requires significantly expanded disclosures about revenue recognition. The provisions of ASU 2014-09 become effective for interim and annual reporting periods beginning after December 15, 2017. Early application is not permitted. First Financial is currently evaluating the impact of this update on its Consolidated Financial Statements. In June 2014, the FASB issued an update (ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures) that requires repurchase-to-maturity transactions to be accounted for as secured borrowings rather than as sales with a forward repurchase commitment and eliminates current guidance on repurchase financings. The ASU requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty. If the derecognition criteria are met, the initial transfer will generally be accounted for as a sale and the repurchase agreement will generally be accounted for as a secured borrowing. The ASU requires new disclosures for repurchase agreements, securities lending transactions and repurchase-to-maturity transactions that are accounted for as secured borrowings. The ASU also requires new disclosures for transfers of financial assets that are accounted for as sales that involve an agreement with the transferee entered into in contemplation of the initial transfer that result in the transferor retaining substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. The provisions of this update became effective for the interim reporting period ended March 31, 2015. This update did not have a material impact on the Company's Consolidated Financial Statements. In August 2014, the FASB issued an update (ASU 2014-14, Receivables - Troubled Debt Restructurings by Creditors: Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure) that requires a mortgage loan be derecognized and a separate other receivable be recognized upon foreclosure if the following conditions are met: a) the loan has a government guarantee that is not separable from the loan before foreclosure, b) at the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim and c) at the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The provisions of this update became effective for the interim reporting period ended March 31, 2015. This update did not have a material impact on the Company's Consolidated Financial Statements. In August 2014, the FASB issued an update (ASU 2014-15, Presentation of Financial Statements-Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern) that requires management perform a going concern evaluation similar to the auditor’s evaluation required by standards issued by the PCAOB and the AICPA. The ASU requires management to evaluate relevant conditions, events and certain management plans that are known or reasonably knowable as of the evaluation date when determining whether substantial doubt about an entity’s ability to continue as a going concern exists for both annual and interim reporting periods. If management concludes that substantial doubt about an entity’s ability to continue as a going concern, the notes to the financial statements are required to include a statement that there is substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The provisions of this update become effective for interim and annual periods ending after December 15, 2016. Early adoption is permitted. First Financial does not anticipate this update will have a material impact on its Consolidated Financial Statements. I n April 2015, the FASB issued an update (ASU 2015-03, Interest-Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs) that requires debt issuance costs to be presented as a deduction from the corresponding debt liability. Upon adoption, an entity must apply the new guidance retrospectively to all prior periods presented in the financial statements. The provisions of this update are effective for interim and annual periods beginning after December 15, 2015, with early adoption permitted. First Financial does not anticipate this update will have a material impact on its Consolidated Financial Statements. In May 2015, the FASB issued an update (ASU 2015-07, Fair Value Measurement: Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share) which will eliminate the requirement to categorize investments whose fair values are measured at net asset value within the fair value hierarchy using the practical expedient. This update will require entities to disclose the fair values of such investments so that financial statement users can reconcile amounts reported in the fair value hierarchy table and the amounts reported on the balance sheet. The provisions of this update become effective for the interim period and annual periods beginning after December 15, 2015, with early adoption permitted. First Financial does not anticipate this update will have a material impact on its Consolidated Financial Statements.

All securities with unrealized losses are reviewed quarterly to determine if any impairment is considered other than temporary, requiring a write-down to fair value. First Financial considers the percentage loss on a security, duration of the loss, average life or duration of the security, credit rating of the security and payment performance as well as the Company's intent and ability to hold the security to maturity when determining whether any impairment is other than temporary. At this time First Financial does not intend to sell, and it is not more likely than not that the Company will be required to sell debt securities temporarily impaired prior to maturity or recovery of the recorded value. First Financial had no other than temporary impairment related to its investment securities portfolio as of June 30, 2015 or December 31, 2014 . For further detail on the fair value of investment securities, see Note 14 – Fair Value Disclosures.

LOANS AND LEASES

LOANS AND LEASES	6 Months Ended

Receivables [Abstract]
LOANS AND LEASES	LOANS AND LEASES First Financial offers clients a variety of commercial and consumer loan and lease products with various interest rates and payment terms. Lending activities are primarily concentrated in Ohio, Indiana and Kentucky, states where the Bank currently operates banking centers. Additionally, First Financial provides equipment and leasehold improvement financing for franchisees in the quick service and casual dining restaurant sector throughout the United States. Commercial loan categories include commercial and industrial (commercial), commercial real estate, construction real estate and lease financing. Consumer loan categories include residential real estate, home equity, installment and credit card. Purchased impaired loans. Loans accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, are referred to as purchased impaired loans. First Financial accounts for the majority of loans acquired in FDIC transactions as purchased impaired loans, except for loans with revolving privileges, which are outside the scope of FASB ASC Topic 310-30, and loans for which cash flows could not be estimated, which are accounted for under the cost recovery method. Purchased impaired loans include loans previously covered under loss sharing agreements as well as loans that remain subject to FDIC loss sharing coverage. Purchased impaired loans are not classified as nonperforming assets as the loans are considered to be performing under FASB ASC Topic 310-30. Therefore, interest income, through accretion of the difference between the carrying value of the loans and the expected cash flows (accretable difference) is recognized on all purchased impaired loans. First Financial had purchased impaired loans totaling $215.2 million and $264.9 million , at June 30, 2015 and December 31, 2014 , respectively. The outstanding balance of all purchased impaired loans, including all contractual principal, interest, fees and penalties, was $262.4 million and $314.5 million as of June 30, 2015 and December 31, 2014 , respectively. These balances exclude contractual interest not yet accrued. Changes in the carrying amount of accretable difference for purchased impaired loans were as follows: Three months ended Six months ended June 30, June 30, (Dollars in thousands) 2015 2014 2015 2014 Balance at beginning of period $ 91,988 $ 131,398 $ 106,622 $ 133,671 Reclassification from/(to) nonaccretable difference (548 ) 8,941 (2,124 ) 22,159 Accretion (5,744 ) (8,932 ) (12,101 ) (18,650 ) Other net activity (1) (6,751 ) (3,643 ) (13,452 ) (9,416 ) Balance at end of period $ 78,945 $ 127,764 $ 78,945 $ 127,764 (1) Includes the impact of loan repayments and charge-offs. First Financial regularly reviews its forecast of expected cash flows for purchased impaired loans. The Company recognized reclassifications from accretable to nonaccretable difference of $0.5 million for the second quarter of 2015 and $2.1 million during the six months ended June 30, 2015 . Conversely, First Financial recognized $8.9 million of reclassifications from nonaccretable to accretable difference during the second quarter of 2014 and $22.2 million during the six months ended June 30, 2014 due to changes in the cash flow expectations related to certain loan pools. These reclassifications can result in impairment and provision expense in the current period or yield adjustments on the related loan pools on a prospective basis. Covered loans. Loans acquired in FDIC-assisted transactions covered under loss sharing agreements whereby the FDIC will reimburse First Financial for the majority of any losses incurred are referred to as covered loans. Pursuant to the terms of the loss sharing agreements, covered loans are subject to a stated loss threshold whereby the FDIC will reimburse First Financial for 80% of losses up to a stated loss threshold and 95% of losses in excess of the threshold. These loss sharing agreements provide for partial loss protection on single-family, residential loans for a period of ten years and First Financial is required to share any recoveries of previously charged-off amounts for the same time period, on the same pro-rata basis with the FDIC. All other loans are provided loss protection for a period of five years and recoveries of previously charged-off amounts must be shared with the FDIC for an additional three year period, on the same pro-rata basis. The Company's loss sharing agreements with the FDIC related to non-single family loans expired effective October 1, 2014, and the ten year period of loss protection on all other covered loans and covered OREO expires October 1, 2019. Covered loans totaled $125.8 million as of June 30, 2015 and $135.7 million as of December 31, 2014 . Credit Quality. To facilitate the monitoring of credit quality for commercial loans, and for purposes of determining an appropriate allowance for loan and lease losses, First Financial utilizes the following categories of credit grades: Pass - Higher quality loans that do not fit any of the other categories described below. Special Mention - First Financial assigns a special mention rating to loans and leases with potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or lease or in First Financial's credit position at some future date. Substandard - First Financial assigns a substandard rating to loans or leases that are inadequately protected by the current sound financial worth and paying capacity of the borrower or of the collateral pledged, if any. Substandard loans and leases have well-defined weaknesses that jeopardize repayment of the debt. Substandard loans and leases are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not addressed. Doubtful - First Financial assigns a doubtful rating to loans and leases with all the attributes of a substandard rating with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors that may work to the advantage and strengthening of the credit quality of the loan or lease, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition or liquidation procedures, capital injection, perfecting liens on additional collateral and refinancing plans. The credit grades described above, which are derived from standard regulatory rating definitions, are assigned upon initial approval of credit to borrowers and updated periodically thereafter. First Financial considers repayment performance to be the best indicator of credit quality for consumer loans. Consumer loans that have principal and interest payments that are past due by 90 days or more are generally classified as nonperforming. Additionally, consumer loans that have been modified in a TDR are also classified as nonperforming.

Loans are classified as nonaccrual when, in the opinion of management, collection of principal or interest is doubtful or when principal or interest payments are 90 days or more past due. Generally, loans are classified as nonaccrual due to the continued failure to adhere to contractual payment terms by the borrower, coupled with other pertinent factors such as insufficient collateral value. The accrual of interest income is discontinued, and previously accrued but unpaid interest is reversed when a loan is classified as nonaccrual. Any payments received while a loan is on nonaccrual status are applied as a reduction to the carrying value of the loan. A loan may return to accrual status if collection of future principal and interest payments is no longer doubtful. Purchased impaired loans are classified as performing, even though they may be contractually past due, as any nonpayment of contractual principal or interest is considered in the periodic re-estimation of expected cash flows and is included in the resulting recognition of current period covered loan loss provision or prospective yield adjustments. Troubled Debt Restructurings. A loan modification is considered a TDR when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made by the Company that would not otherwise be considered for a borrower with similar credit characteristics. The most common types of modifications include interest rate reductions, maturity extensions and modifications to principal amortization, including interest only structures. Modified terms are dependent upon the financial position and needs of the individual borrower. If the modification agreement is violated, the loan is managed by the Company’s credit administration group for resolution, which may result in foreclosure in the case of real estate. TDRs are generally classified as nonaccrual for a minimum period of six months and may qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement. First Financial had 272 TDRs totaling $34.2 million at June 30, 2015 , including $20.1 million on accrual status and $14.1 million classified as nonaccrual. First Financial had an insignificant amount of commitments outstanding to lend additional funds to borrowers whose loan terms have been modified through TDRs at June 30, 2015 . At June 30, 2015 , the allowance for loan and lease losses included reserves of $3.4 million related to TDRs. For the three and six months ended June 30, 2015 , First Financial charged off $1.7 million for the portion of TDRs determined to be uncollectible. Additionally, at June 30, 2015 , approximately $8.1 million of accruing TDRs have been performing in accordance with the restructured terms for more than one year. First Financial had 262 TDRs totaling $28.2 million at December 31, 2014 , including $15.9 million of loans on accrual status and $12.3 million classified as nonaccrual. First Financial had an insignificant amount of commitments outstanding to lend additional funds to borrowers whose loan terms had been modified through TDRs. At December 31, 2014 , the allowance for loan and lease losses included reserves of $3.7 million related to TDRs. For the year ended December 31, 2014 , First Financial charged off $1.0 million for the portion of TDRs determined to be uncollectible. At December 31, 2014 , approximately $10.5 million of the accruing TDRs had been performing in accordance with the restructured terms for more than one year.

Borrowers classified as a TDR that are 90 days or more past due on any principal or interest payments, or who prematurely terminate a restructured loan agreement without paying off the contractual principal balance (for example, in a deed-in-lieu arrangement), are considered to be in payment default of the terms of the TDR agreement.

The primary activities impacting the FDIC indemnification asset are FDIC claims, amortization, FDIC loss sharing income and accelerated discount. FDIC claims - First Financial files quarterly certifications with the FDIC and submits claims for losses, valuation adjustments and collection expenses incurred, less recoveries of any previous amounts claimed that are reimbursable back to the FDIC, as allowed under the loss sharing agreements. Cash reimbursements are generally received within 30 days of filing and are recorded as a credit to the indemnification asset balance, thus reducing its carrying value. Amortization - As the yield on covered loans increased over time as a result of improvement in the expected cash flows on covered loans, the yield on the indemnification asset declined. The yield on the indemnification asset became negative in the first quarter of 2011 at which time the indemnification asset began to decline through monthly amortization at the negative yield. FDIC loss sharing income - FDIC loss sharing income represents the proportionate share of credit costs on covered assets that First Financial expects to receive from the FDIC. Credit costs on covered assets include provision expense on covered loans, losses on covered OREO and other covered collection and asset resolution costs recorded as loss sharing expense under noninterest expenses in the Consolidated Statements of Income. Offset to accelerated discount - Accelerated discounts on covered loans occur when covered loans prepay and represent the accelerated recognition of the remaining discount that would have been recognized over the life of the loan had the loan not prepaid. In conjunction with the recognition of accelerated discount, First Financial also recognizes a related offset through noninterest income and reduction to the indemnification asset for a portion of the discount representing expected credit loss included in the discount recorded at acquisition.

ALLOWANCE FOR LOAN AND LEASE LO

ALLOWANCE FOR LOAN AND LEASE LOSSES	6 Months Ended

Receivables [Abstract]
ALLOWANCE FOR LOAN AND LEASE LOSSES	ALLOWANCE FOR LOAN AND LEASE LOSSES Loans and leases. For each reporting period, management maintains the allowance for loan and lease losses at a level that it considers sufficient to absorb probable loan and lease losses inherent in the portfolio. Management determines the adequacy of the allowance based on historical loss experience as well as other significant factors such as composition of the portfolio, economic conditions, geographic footprint, the results of periodic internal and external evaluations of delinquent, nonaccrual and classified loans and any other adverse situations that may affect a specific borrower's ability to repay (including the timing of future payments). This evaluation is inherently subjective as it requires utilizing material estimates that may be susceptible to significant change. There were no material changes to First Financial's accounting policies or methodology related to the allowance for loan and lease losses during the first six months of 2015 . The allowance is increased by provision expense and decreased by actual charge-offs, net of recoveries of amounts previously charged-off. First Financial's policy is to charge-off all or a portion of a loan when, in management's opinion, it is unlikely to collect the principal amount owed in full either through payments from the borrower or from the liquidation of collateral. During 2014, First Financial completed the mergers of The First Bexley Bank (First Bexley), Insight Bank (Insight) and Guernsey Bancorp, Inc (Guernsey). Loans acquired in connection with those mergers were recorded at estimated fair value at the acquisition date with no carryover of the related ALLL. See Note 15 - Business Combinations for further detail. Covered/formerly covered loans. The majority of covered/formerly covered loans are purchased impaired loans, whereby First Financial is required to periodically re-estimate the expected cash flows on the loans. First Financial updated the valuations related to covered/formerly covered loans during the second quarter of 2015 . First Financial recognized provision expense of $0.7 million and net charge-offs of $0.2 million during the second quarter of 2015, resulting in an ending allowance of $10.7 million as of June 30, 2015 . First Financial recognized provision expense of $0.4 million and realized net recoveries of $0.3 million for the first six months of 2015. For the second quarter of 2014 , First Financial recognized negative provision expense, or impairment recapture, on covered loans of $0.4 million and net recoveries of $2.3 million , resulting in an ending allowance of $12.4 million . For the first six months of 2014, the Company recognized negative provision expense on covered loans of $2.6 million and net charge-offs of $3.9 million . First Financial recognized loss sharing expenses of $0.6 million and $1.5 million for the second quarters of 2015 and 2014 , respectively. The Company also recognized gains on covered/formerly covered OREO of $0.1 million for the second quarter of 2015 and losses on covered OREO of $0.4 million for the second quarter of 2014 . The net payable due to the FDIC under loss sharing agreements related to covered loan recoveries, gains/losses on covered OREO and loss sharing expenses of $0.3 million was recognized as negative FDIC loss sharing income and a corresponding decrease to the FDIC indemnification asset during the second quarter of 2015 . The net receivable due from the FDIC under loss sharing agreements of $1.1 million for the second quarter of 2014 , was recognized as FDIC loss sharing income and a corresponding increase to the FDIC indemnification asset. First Financial recognized loss sharing expenses of $0.9 million and $3.0 million for the six months ended June 30, 2015 and 2014, respectively. First Financial also recognized losses on covered/formerly covered OREO of $0.4 million for the six months ended June 30, 2015 and 2014, respectively. The net payable due to the FDIC under loss sharing agreements of $1.4 million for the first six months of 2015, was recognized as negative loss sharing income and a corresponding decrease to the FDIC indemnification asset. The receivable due from the FDIC under loss sharing agreements of $0.6 million for the first six months of 2014, was recognized as loss sharing income and a corresponding increase to the FDIC indemnification asset.

GOODWILL AND OTHER INTANGIBLE ASSETS	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill. Assets and liabilities acquired in a business combination are recorded at their estimated fair values as of the acquisition date. The excess cost of the acquisition over the fair value of net assets acquired is recorded as goodwill. During the third quarter of 2014, First Financial recorded additions to goodwill related to the acquisitions of First Bexley, Insight and Guernsey. For further detail, see Note 15 – Business Combinations. Goodwill is not amortized, but is measured for impairment on an annual basis as of October 1 of each year, or whenever events or changes in circumstances indicate that the fair value of a reporting unit may be below its carrying value. First Financial performed its most recent annual impairment test as of October 1, 2014 and no impairment was indicated. As of June 30, 2015 , no events or changes in circumstances indicated that the fair value of a reporting unit was below its carrying value, and no changes to goodwill were recorded for the quarter ended June 30, 2015 . Therefore, as of June 30, 2015 and December 31, 2014 , First Financial had goodwill of $137.7 million . Other intangible assets. Other intangible assets primarily consists of core deposit intangibles. Core deposit intangibles represent the estimated fair value of acquired customer deposit relationships. Core deposit intangibles are recorded at their estimated fair value as of the acquisition date and are then amortized on an accelerated basis over their estimated useful lives. Core deposit intangibles were $6.8 million and $7.7 million as of June 30, 2015 and December 31, 2014 , respectively. First Financial's core deposit intangibles have an estimated weighted average remaining life of 6.1 years . Amortization expense was $0.4 million and $0.3 million for the three months ended June 30, 2015 and 2014 , respectively. Amortization expense recognized on intangible assets for the six months ended June 30, 2015 and 2014 was $0.9 million and $0.7 million , respectively.

This facility can have a variable or fixed interest rate and provides First Financial additional liquidity, if needed, for various corporate activities, including the repurchase of First Financial shares and the payment of dividends to shareholders. As of June 30, 2015 and December 31, 2014 , there was no outstanding balance. The credit agreement requires First Financial to comply with certain covenants including those related to asset quality and capital levels, and First Financial was in compliance with all covenants associated with this line of credit as of June 30, 2015 and December 31, 2014 . Long-term debt primarily consists of FHLB long-term advances and repurchase agreements utilizing investment securities pledged as collateral. These instruments are primarily utilized to reduce overnight liquidity risk and to mitigate interest rate sensitivity on the Consolidated Balance Sheets. First Financial has $25.0 million in repurchase agreements which have remaining maturities of less than 1 year and a weighted average rate of 3.54% as of June 30, 2015 and December 31, 2014.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES First Financial uses derivative instruments, including interest rate caps, floors and swaps, to meet the needs of its clients while managing the interest rate risk associated with certain transactions. First Financial does not use derivatives for speculative purposes. First Financial primarily utilizes interest rate swaps as a means to offer borrowers credit-based products that meet their needs and may from time to time utilize interest rate swaps to manage the interest rate risk profile of the Company. Interest rate swap agreements establish the basis on which interest rate payments are exchanged with counterparties, referred to as the notional amount. As only interest rate payments are exchanged, the cash requirements and credit risk associated with interest rate swaps are significantly less than the notional amount and the Company’s credit risk exposure is limited to the market value of the instruments. First Financial manages this market value credit risk through counterparty credit policies. These policies require the Company to maintain a total derivative notional position of less than 35% of assets, total credit exposure of less than 3% of capital and no single counterparty credit risk exposure greater than $20.0 million . The Company is currently below all single counterparty and portfolio limits. At June 30, 2015 , the Company had a total counterparty notional amount outstanding of approximately $490.0 million , spread among seven counterparties, with an outstanding liability from these contracts of $10.6 million . At December 31, 2014 , the Company had a total counterparty notional amount outstanding of approximately $566.2 million , spread among nine counterparties, with an outstanding liability from these contracts of $12.4 million . First Financial’s exposure to credit loss, in the event of nonperformance by a borrower, is limited to the market value of the derivative instrument associated with that borrower. First Financial monitors its derivative credit exposure to borrowers by monitoring the creditworthiness of the related loan customers through the normal credit review processes the Company performs on all borrowers. Additionally, the Company monitors derivative credit risk exposure related to problem loans through the Company's allowance for loan and lease losses committee. First Financial considers the market value of a derivative instrument to be part of the carrying value of the related loan for these purposes as the borrower is contractually obligated to pay First Financial this amount in the event the derivative contract is terminated. Fair Value Hedges. First Financial utilizes interest rate swaps designated as fair value hedges as a means to offer commercial borrowers fixed rate funding while providing the Company with floating rate assets. The following table details the location and amounts recognized in the Consolidated Balance Sheets for fair value hedges: June 30, 2015 December 31, 2014 Estimated fair value Estimated fair value (Dollars in thousands) Balance sheet location Notional amount Gain Loss Notional amount Gain Loss Fair value hedges - instruments associated with loans Pay fixed interest rate swaps with counterparty Accrued interest and other liabilities $ 6,819 $ 0 $ (299 ) $ 8,739 $ 0 $ (440 ) Matched interest rate swaps with borrower Accrued interest and other assets 483,183 11,240 (478 ) 407,423 11,150 (249 ) Matched interest rate swaps with counterparty Accrued interest and other liabilities 483,183 478 (11,298 ) 407,423 249 (11,227 ) Total $ 973,185 $ 11,718 $ (12,075 ) $ 823,585 $ 11,399 $ (11,916 ) In connection with its use of derivative instruments, First Financial and its counterparties are required to post cash collateral to offset the market position of the derivative instruments under certain conditions. First Financial maintains the right to offset these derivative positions with the collateral posted against them by or with the relevant counterparties. First Financial classifies the derivative cash collateral outstanding with its counterparties as an adjustment to the fair value of the derivative contracts within Accrued interest and other assets or Accrued interest and other liabilities in the Consolidated Balance Sheets. The following table discloses the gross and net amounts of liabilities recognized in the Consolidated Balance Sheets: June 30, 2015 December 31, 2014 (Dollars in thousands) Gross amounts of recognized liabilities Gross amounts offset in the Consolidated Balance Sheets Net amounts of liabilities presented in the Consolidated Balance Sheets Gross amounts of recognized liabilities Gross amounts offset in the Consolidated Balance Sheets Net amounts of assets presented in the Consolidated Balance Sheets Fair value hedges Pay fixed interest rate swaps with counterparty $ 299 $ 0 $ 299 $ 440 $ 0 $ 440 Matched interest rate swaps with counterparty 11,776 (9,852 ) 1,924 11,476 (12,260 ) (784 ) Total $ 12,075 $ (9,852 ) $ 2,223 $ 11,916 $ (12,260 ) $ (344 ) The following table details the derivative financial instruments, the average remaining maturities and the weighted-average interest rates being paid and received by First Financial at June 30, 2015 : Weighted-average rate (Dollars in thousands) Notional amount Average maturity (years) Fair value Receive Pay Asset conversion swaps Pay fixed interest rate swaps with counterparty $ 6,819 1.7 $ (299 ) 2.04 % 6.86 % Receive fixed, matched interest rate swaps with borrower 483,183 4.3 10,762 4.53 % 2.60 % Pay fixed, matched interest rate swaps with counterparty 483,183 4.3 (10,820 ) 2.60 % 4.53 % Total asset conversion swaps $ 973,185 4.3 $ (357 ) 3.55 % 3.59 % Cash Flow Hedges. First Financial utilizes interest rate swaps designated as cash flow hedges to hedge against interest rate volatility on indexed floating rate deposits. These interest rate swaps qualify for hedge accounting and involved the receipt by First Financial of variable-rate interest amounts in exchange for fixed-rate interest payments by First Financial. As of December 31, 2014 , the Company had active interest rate swaps with a notional value of $150.0 million . Accrued interest and other liabilities included $1.7 million at December 31, 2014 , reflecting the fair value of the cash flow hedges. First Financial terminated all cash flow hedges during the second quarter 2015. Credit Derivatives. In conjunction with participating interests in commercial loans, First Financial periodically enters into risk participation agreements with other counterparties whereby First Financial assumes a portion of the credit exposure associated with an interest rate swap on the participated loan in exchange for a fee. Under these agreements, First Financial will make payments to the counterparty if the loan customer defaults on its obligation to perform under the interest rate swap contract with the counterparty. The total notional value of these agreements totaled $26.1 million as of June 30, 2015 and $26.4 million as of December 31, 2014 . The fair value of these agreements were recorded on the Consolidated Balance Sheets as Accrued interest and other liabilities of $0.1 million as of June 30, 2015 and December 31, 2014 . Mortgage Derivatives. First Financial enters into IRLCs and forward commitments for the future delivery of mortgage loans to third party investors, which are considered derivatives. When borrowers secure an IRLC with First Financial and the loan is intended to be sold, First Financial will enter into forward commitments for the future delivery of the loans to third party investors in order to hedge against the effect of changes in interest rates. At June 30, 2015, the notional amount of the interest rate lock commitments was $31.7 million and the notional amount of forward commitments was $54.3 million . The fair value of these agreements was $0.1 million as of June 30, 2015 and was recorded on the Consolidated Balance Sheets in Accrued interest and other assets.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES For the second quarter 2015 , income tax expense was $9.3 million , resulting in an effective tax rate of 32.9% , compared with income tax expense of $8.0 million and an effective tax rate of 33.3% for the comparable period in 2014 . For the first six months of 2015 , income tax expense was $17.7 million , resulting in an effective tax rate of 32.7% . compared with income tax expense of $15.0 million and an effective tax rate of 32.6% for the comparable period in 2014. The decrease in the effective tax rate for the second quarter 2015, as compared to the same period in 2014, was primarily the result of an increase in tax-exempt income during the period. At June 30, 2015 , and December 31, 2014 , First Financial had no FASB ASC Topic 740-10 unrecognized tax benefits recorded. First Financial does not expect the total amount of unrecognized tax benefits to significantly increase within the next twelve months. First Financial regularly reviews its tax positions and establishes reserves for income tax-related uncertainties based on estimates of whether it is more likely than not that the tax uncertainty would be sustained upon challenge by the appropriate tax authorities, which would then result in additional taxes, penalties and interest due. These evaluations are inherently subjective as they require material estimates and may be susceptible to significant change. Management determined that no reserve for income tax-related uncertainties was necessary as of June 30, 2015 and December 31, 2014 . First Financial and its subsidiaries are subject to U.S. federal income tax as well as state and local income tax in several jurisdictions. Tax years prior to 2011 have been closed and are no longer subject to U.S. federal income tax examinations. The tax year 2012 is currently under examination by the federal taxing authority. At this time, First Financial is not aware of any material impact to the Company's financial position and results of operations as a result of this examination. Tax years 2011 through 2014 remain open to examination by the federal taxing authority. First Financial is no longer subject to state and local income tax examinations for years prior to 2010. Tax years 2010 through 2014 remain open to state and local examination in various jurisdictions.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES In the normal course of business, First Financial offers a variety of financial instruments with off-balance-sheet risk to assist clients in meeting their requirements for liquidity and credit enhancement. These financial instruments include standby letters of credit and outstanding commitments to extend credit. GAAP does not require these financial instruments to be recorded in the Consolidated Financial Statements. First Financial’s exposure to credit loss, in the event of nonperformance by the counterparty to the financial instrument for standby letters of credit and outstanding commitments to extend credit, is represented by the contractual amounts of those instruments. First Financial uses the same credit policies in issuing commitments and conditional obligations as it does for credit instruments recorded on the Consolidated Balance Sheets. First Financial utilizes the allowance for loan and lease losses methodology to maintain a reserve that it considers sufficient to absorb probable losses inherent in standby letters of credit and outstanding loan commitments and records the reserve within Accrued interest and other liabilities on the Consolidated Balance Sheets. Loan commitments. Loan commitments are agreements to extend credit to a client, absent any violation of conditions established in the commitment agreement. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if deemed necessary by First Financial upon extension of credit, is based on management’s credit evaluation of the client. The collateral held varies, but may include securities, real estate, inventory, plant or equipment. First Financial had commitments outstanding to extend credit totaling $1.9 billion and $1.8 billion at June 30, 2015 and December 31, 2014 , respectively. Letters of credit. Letters of credit are conditional commitments issued by First Financial to guarantee the performance of a client to a third party. First Financial’s portfolio of standby letters of credit consists primarily of performance assurances made on behalf of clients who have a contractual commitment to produce or deliver goods or services. The risk to First Financial arises from its obligation to make payment in the event of the client's contractual default to produce the contracted good or service to a third party. First Financial issued letters of credit (including standby letters of credit) aggregating $16.5 million and $22.8 million at June 30, 2015 , and December 31, 2014 , respectively. Management conducts regular reviews of these instruments on an individual client basis. Investments in Affordable housing projects. First Financial has made investments in certain qualified affordable housing projects. These projects provide tax incentives to encourage investment in the development, acquisition and rehabilitation of affordable rental housing, and First Financial receives corresponding tax credits that are an indirect federal subsidy that finances low-income housing and allows investors to claim tax credits and other tax benefits (such as deductions from taxable income for operating losses) on their federal income tax returns. The principal risk associated with qualified affordable housing investments is the potential for noncompliance with the tax code requirements, such as, failure to rent property to qualified tenants, resulting in unavailability or recapture of the tax credits and other tax benefits. First Financial's affordable housing commitments totaled $24.4 million and $14.9 million as of June 30, 2015 and December 31, 2014 , respectively. First Financial had no affordable housing contingent commitments as of June 30, 2015 or December 31, 2014 . The affordable housing investments resulted in $0.3 million of tax credits for the three months ended June 30, 2015 and 2014 , and $0.7 million and $0.6 million for the six months ended June 30, 2015 and 2014 , respectively. Contingencies/Litigation. First Financial and its subsidiaries are engaged in various matters of litigation, other assertions of improper or fraudulent loan practices or lending violations and other matters from time to time, and have a number of unresolved claims pending. Additionally, as part of the ordinary course of business, First Financial and its subsidiaries are parties to litigation involving claims to the ownership of funds in particular accounts, the collection of delinquent accounts, challenges to security interests in collateral and foreclosure interests that are incidental to our regular business activities. While the ultimate liability with respect to these other litigation matters and claims cannot be determined at this time, First Financial believes that damages, if any, and other amounts relating to pending matters are not probable or cannot be reasonably estimated as of June 30, 2015 . Reserves are established for these various matters of litigation, when appropriate, under FASB ASC Topic 450, Contingencies, based in part upon the advice of legal counsel.

These warrants, each representing the right to purchase one share of common stock, no par value per share, have an exercise price of $12.12 and expire on December 23, 2018. Stock options and warrants, where the exercise price was greater than the average market price of the common shares, were not included in the computation of net income per diluted share as they would have been antidilutive. These out-of-the-money options were 3,300 and 174,426 using the period-end price at June 30, 2015 and 2014 , respectively. During the second quarter of 2014, the Company received shareholder authorization to issue up to 10,000,000 preferred shares. As of June 30, 2015 , no preferred shares were issued or outstanding.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	FAIR VALUE DISCLOSURES Fair Value Measurement The fair value framework as disclosed in the Fair Value Measurements and Disclosure Topic of FASB ASC Topic 825, Financial Instruments (Fair Value Topic) includes a hierarchy which focuses on prioritizing the inputs used in valuation techniques. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1), a lower priority to observable inputs other than quoted prices in active markets for identical assets and liabilities (Level 2) and the lowest priority to unobservable inputs (Level 3). When determining the fair value measurements for assets and liabilities, First Financial looks to active markets to price identical assets or liabilities whenever possible and classifies such items in Level 1. When identical assets and liabilities are not traded in active markets, First Financial looks to observable market data for similar assets and liabilities and classifies such items as Level 2. Certain assets and liabilities are not actively traded in observable markets and First Financial must use alternative techniques, based on unobservable inputs, to determine the fair value and classifies such items as Level 3. The level within the fair value hierarchy is based on the lowest level of input that is significant in the fair value measurement. The following methods, assumptions and valuation techniques were used by First Financial to measure different financial assets and liabilities at fair value and in estimating its fair value disclosures for financial instruments. Cash and short-term investments. The carrying amounts reported in the Consolidated Balance Sheets for cash and short-term investments, such as federal funds sold, approximated the fair value of those instruments. The Company classifies cash and short-term investments in Level 1 of the fair value hierarchy. Investment securities. Investment securities classified as trading and available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar investment securities. First Financial compiles prices from various sources who may apply such techniques as matrix pricing to determine the value of identical or similar investment securities (Level 2). Matrix pricing is a mathematical technique widely used in the banking industry to value investment securities without relying exclusively on quoted prices for the specific investment securities but rather relying on the investment securities’ relationship to other benchmark quoted investment securities. Any investment securities not valued based upon the methods above are considered Level 3. First Financial utilizes information provided by third-party pricing vendors to analyze the investment securities portfolio in accordance with the fair value hierarchy of the Fair Value Topic and reviews the pricing methodologies utilized by the pricing vendors to ensure that the fair value determination is consistent with the applicable accounting guidance. First Financial’s month-end pricing process includes a series of quality assurance activities where prices are compared to recent market conditions, historical prices and other independent pricing services. Further, the Company periodically validates the fair values of a sample of securities in the portfolio by comparing the fair values to prices from other independent sources for the same or similar securities. First Financial analyzes unusual or significant variances, conducts additional research with the pricing vendor, and if necessary, takes appropriate action based on its findings. The results of the quality assurance process are incorporated into the selection of pricing providers by the portfolio manager. Loans held for sale. Loans held for sale are carried at the lower of cost or fair value. These loans currently consist of one-to-four family residential real estate loans originated for sale to qualified third parties. Fair value is based on the contractual price to be received from these third parties, which is not materially different than cost due to the short duration between origination and sale (Level 2). As such, First Financial records any fair value adjustments on a nonrecurring basis. Gains and losses on the sale of loans are recorded as net gains from sales of loans within noninterest income in the Consolidated Statements of Income. Loans and leases. The fair value of commercial, commercial real estate, residential real estate and consumer loans were estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or repricing frequency. The Company classifies the estimated fair value of loans as Level 3 in the fair value hierarchy. Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected. Impaired loans are valued at the lower of cost or fair value for purposes of determining the appropriate amount of impairment to be allocated to the allowance for loan and lease losses. Fair value is generally measured based on the value of the collateral securing the loans. Collateral may be in the form of real estate or business assets including equipment, inventory and accounts receivable. The vast majority of the collateral is real estate. The value of real estate collateral is determined utilizing an income or market valuation approach based on an appraisal conducted by an independent, licensed third-party appraiser (Level 3). The value of business equipment is based upon an outside appraisal if deemed significant, or the net book value on the applicable borrower financial statements if not considered significant. Likewise, values for inventory and accounts receivable collateral are based on borrower financial statement balances or aging reports on a discounted basis as appropriate (Level 3). Impaired loans allocated to the allowance for loan and lease losses are measured at fair value on a nonrecurring basis. Any fair value adjustments are recorded in the period incurred as provision for loan and lease losses on the Consolidated Statements of Income. Fair values for purchased impaired loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company's assessment of risk inherent in the cash flow estimates. These loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. First Financial estimated the cash flows expected to be collected on these loans based upon the expected remaining life of the underlying loans, which includes the effects of estimated prepayments. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change. Fair values for acquired loans accounted for outside of FASB ASC Topic 310-30 were estimated by discounting the future cash flows using current interest rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or repricing frequency. The carrying amount of accrued interest approximates its fair value. The Company classifies the estimated fair value of covered loans as Level 3 in the fair value hierarchy. FDIC indemnification asset. Fair value of the FDIC indemnification asset was estimated using projected cash flows related to the loss sharing agreements based on expected reimbursements for losses and the applicable loss sharing percentages. The expected cash flows are discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change, and may be impacted by the relatively short remaining term of loss sharing coverage on covered commercial assets. The five year period of loss protection expired for the majority of First Financial's covered commercial loans and covered OREO effective October 1, 2014. The Company classifies the estimated fair value of the indemnification asset as Level 3 in the fair value hierarchy. Deposits. The fair value of demand deposits, savings accounts and certain money-market deposits was the amount payable on demand at the reporting date. The carrying amounts for variable-rate certificates of deposit approximated their fair values at the reporting date. The fair value of fixed-rate certificates of deposit was estimated using a discounted cash flow calculation which applies the interest rates currently offered for deposits of similar remaining maturities. The carrying amount of accrued interest approximates its fair value. The Company classifies the estimated fair value of deposit liabilities as Level 2 in the fair value hierarchy. Borrowings. The carrying amounts of federal funds purchased and securities sold under agreements to repurchase and other short-term borrowings approximate their fair values. The Company classifies the estimated fair value of short-term borrowings as Level 1 of the fair value hierarchy. The fair value of long-term debt is estimated using a discounted cash flow calculation which utilizes the interest rates currently offered for borrowings of similar remaining maturities. Third-party valuations are used for long-term debt with embedded options, such as call features. The Company classifies the estimated fair value of long-term debt as Level 2 in the fair value hierarchy. Commitments to extend credit and standby letters of credit. Pricing of these financial instruments is based on the credit quality and relationship, fees, interest rates, probability of funding and compensating balance and other covenants or requirements. Loan commitments generally have fixed expiration dates, are variable rate and contain termination and other clauses which provide for relief from funding in the event that there is a significant deterioration in the credit quality of the client. Many loan commitments are expected to expire without being drawn upon. The rates and terms of the commitments to extend credit and the standby letters of credit are competitive with those in First Financial’s market area. The carrying amounts are reasonable estimates of the fair value of these financial instruments. Carrying amounts, which are comprised of the unamortized fee income and, where necessary, reserves for any expected credit losses from these financial instruments, are immaterial. Derivatives. The fair values of derivative instruments are based primarily on a net present value calculation of the cash flows related to the interest rate swaps at the reporting date, using primarily observable market inputs such as interest rate yield curves. The discounted net present value calculated represents the cost to terminate the swap if First Financial should choose to do so. Additionally, First Financial utilizes a vendor-developed, proprietary model to value the credit risk component of both the derivative assets and liabilities. The credit valuation adjustment is recorded as an adjustment to the fair value of the derivative asset or liability on the reporting date. Derivative instruments are classified as Level 2 in the fair value hierarchy. The estimated fair values of First Financial’s financial instruments not measured at fair value on a recurring or nonrecurring basis in the consolidated financial statements were as follows: Carrying Estimated fair value (Dollars in thousands) value Total Level 1 Level 2 Level 3 June 30, 2015 Financial assets Cash and short-term investments $ 157,345 $ 157,345 $ 157,345 $ 0 $ 0 Investment securities held-to-maturity 791,839 799,796 0 799,796 0 Other investments 53,585 53,585 0 53,585 0 Loans held for sale 21,151 21,151 0 21,151 0 Loans and leases, net of ALLL 4,799,898 4,846,663 0 0 4,846,663 FDIC indemnification asset 20,338 11,253 0 0 11,253 Financial liabilities Deposits Noninterest-bearing $ 1,330,149 $ 1,330,149 $ 0 $ 1,330,149 $ 0 Interest-bearing demand 1,175,219 1,175,219 0 1,175,219 0 Savings 1,947,566 1,947,566 0 1,947,566 0 Time 1,262,881 1,262,533 0 1,262,533 0 Total deposits 5,715,815 5,715,467 0 5,715,467 0 Short-term borrowings 710,049 710,049 710,049 0 0 Long-term debt 47,084 47,920 0 47,920 0 Carrying Estimated fair value (Dollars in thousands) value Total Level 1 Level 2 Level 3 December 31, 2014 Financial assets Cash and short-term investments $ 132,752 $ 132,752 $ 132,752 $ 0 $ 0 Investment securities held-to-maturity 867,996 874,749 0 874,749 0 Other investments 52,626 52,626 0 52,626 0 Loans held for sale 11,005 11,005 0 11,005 0 Loans and leases, net of ALLL 4,724,377 4,763,619 0 0 4,763,619 FDIC indemnification asset 22,666 12,449 0 0 12,449 Financial liabilities Deposits Noninterest-bearing $ 1,285,527 $ 1,285,527 $ 0 $ 1,285,527 $ 0 Interest-bearing demand 1,225,378 1,225,378 0 1,225,378 0 Savings 1,889,473 1,889,473 0 1,889,473 0 Time 1,255,364 1,254,070 0 1,254,070 0 Total deposits 5,655,742 5,654,448 0 5,654,448 0 Short-term borrowings 661,392 661,392 661,392 0 0 Long-term debt 48,241 49,674 0 49,674 0 The financial assets and liabilities measured at fair value on a recurring basis in the consolidated financial statements were as follows: Fair value measurements using (Dollars in thousands) Level 1 Level 2 Level 3 Assets/liabilities at fair value June 30, 2015 Assets Derivatives $ 0 $ 11,813 $ 0 $ 11,813 Investment securities available-for-sale 8,465 947,299 0 955,764 Total $ 8,465 $ 959,112 $ 0 $ 967,577 Liabilities Derivatives $ 0 $ 12,125 $ 0 $ 12,125 Fair value measurements using (Dollars in thousands) Level 1 Level 2 Level 3 Assets/liabilities at fair value December 31, 2014 Assets Derivatives $ 0 $ 11,399 $ 0 $ 11,399 Investment securities available-for-sale 8,406 832,062 0 840,468 Total $ 8,406 $ 843,461 $ 0 $ 851,867 Liabilities Derivatives $ 0 $ 13,662 $ 0 $ 13,662 Certain financial assets and liabilities are measured at fair value on a nonrecurring basis.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS First Financial completed three business combinations in the Columbus, Ohio market during 2014 as follows: First Bexley. Founded in 2006 and conducting operations out of one full service branch location in Bexley, Ohio, First Bexley served commercial and consumer clients throughout Columbus and central Ohio. Under the merger agreement, First Financial acquired First Bexley in a cash and stock transaction in which First Bexley was merged with and into First Financial Bank on August 7, 2014. Insight. Insight was founded in 2006 and conducted operations out of one full service location in Worthington, Ohio, and a mortgage origination office in Newark, Ohio, and provided commercial and consumer banking services to clients throughout Columbus and central Ohio. Under the merger agreement, First Financial acquired Insight in a cash and stock transaction in which Insight merged with and into First Financial Bank on August 7, 2014. Guernsey. Headquartered in Worthington, Ohio, Guernsey conducted operations out of three full service branches, and served commercial and consumer clients throughout Columbus and central Ohio. Under the terms of the merger agreement, First Financial acquired Guernsey for cash consideration and the transfer of a single bank-owned property to Guernsey's sole shareholder. The Company also paid off all amounts due under a promissory note to a third party on behalf of Guernsey. The Guernsey Bank, an Ohio state chartered bank and wholly-owned subsidiary of Guernsey, merged with and into First Financial as part of the agreement on August 21, 2014. The First Bexley, Insight and Guernsey transactions were accounted for using the acquisition method of accounting and accordingly, assets acquired, liabilities assumed and consideration exchanged were recorded at estimated fair value on the acquisition dates, in accordance with FASB ASC Topic 805, Business Combinations. The fair value measurements of assets acquired and liabilities assumed are subject to refinement for up to one year after the closing date of the acquisitions as additional information relative to closing date fair values become available. The Company continues to finalize the fair values of loans and intangible assets and liabilities. As a result, the fair value adjustment in the accounts are preliminary and may change as information becomes available but no later than August 2015. The following table provides the purchase price calculation as of the acquisition dates and the identifiable assets purchased and the liabilities assumed at their estimated fair value. These fair value measurements are based on third-party valuations.

The goodwill arising from the First Bexley and Insight transactions is not deductible for income tax purposes as the mergers were accounted for as tax-free exchanges. The tax-free exchanges resulted in a carryover of tax attributes and tax basis to the Company's subsequent income tax filings and was adjusted for any fair value adjustments required in accounting for the acquisitions. The goodwill arising from the Guernsey transaction is deductible for tax purposes as the Guernsey transaction is considered a taxable exchange.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2015
Basis of Presentation Policy	The Consolidated Financial Statements of First Financial Bancorp., a bank holding company, principally serving Ohio, Indiana and Kentucky, include the accounts and operations of First Financial and its wholly-owned subsidiary, First Financial Bank, N.A. All significant intercompany transactions and accounts have been eliminated in consolidation. Certain reclassifications of prior periods' amounts, including covered loans and the related allowance for loan and lease losses in the Consolidated Balance Sheets have been made to conform to current year presentation. Such reclassifications had no effect on net earnings. Effective October 1, 2014, the five-year loss sharing coverage period for non-single family assets expired and the majority of the Company’s formerly covered assets were no longer subject to FDIC loss sharing protection. As a result of this expiration, and the insignificant balance of assets that remain subject to FDIC loss sharing protection through October 1, 2019 relative to the Company’s total assets, all covered loans and the related allowance for loan and lease losses, as well as provision for covered loan and lease losses, have been reclassified in the Consolidated Financial Statements, and all credit quality metrics have been updated to include covered and formerly covered assets.
Use of Estimates, Policy	The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. These estimates, assumptions and judgments are inherently subjective and may be susceptible to significant change. Actual realized amounts could differ materially from these estimates.
Certain Loans and Debt Securities Acquired in Transfer, Recognizing Interest Income on Impaired Loans, Policy	Loans accounted for under FASB ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, are referred to as purchased impaired loans. First Financial accounts for the majority of loans acquired in FDIC transactions as purchased impaired loans, except for loans with revolving privileges, which are outside the scope of FASB ASC Topic 310-30, and loans for which cash flows could not be estimated, which are accounted for under the cost recovery method. Purchased impaired loans include loans previously covered under loss sharing agreements as well as loans that remain subject to FDIC loss sharing coverage. Purchased impaired loans are not classified as nonperforming assets as the loans are considered to be performing under FASB ASC Topic 310-30. Therefore, interest income, through accretion of the difference between the carrying value of the loans and the expected cash flows (accretable difference) is recognized on all purchased impaired loans.
Loans and Leases Receivable, Past Due Status, Policy	Loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement or any portion thereof remains unpaid after the date of the scheduled payment.
Loans and Leases Receivable, Nonaccrual Loan and Lease Status, Policy	Loans are classified as nonaccrual when, in the opinion of management, collection of principal or interest is doubtful or when principal or interest payments are 90 days or more past due. Generally, loans are classified as nonaccrual due to the continued failure to adhere to contractual payment terms by the borrower, coupled with other pertinent factors such as insufficient collateral value. The accrual of interest income is discontinued, and previously accrued but unpaid interest is reversed when a loan is classified as nonaccrual. Any payments received while a loan is on nonaccrual status are applied as a reduction to the carrying value of the loan. A loan may return to accrual status if collection of future principal and interest payments is no longer doubtful. Purchased impaired loans are classified as performing, even though they may be contractually past due, as any nonpayment of contractual principal or interest is considered in the periodic re-estimation of expected cash flows and is included in the resulting recognition of current period covered loan loss provision or prospective yield adjustments.
Loans and Leases Receivable, Troubled Debt Restructuring Policy	A loan modification is considered a TDR when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made by the Company that would not otherwise be considered for a borrower with similar credit characteristics. The most common types of modifications include interest rate reductions, maturity extensions and modifications to principal amortization, including interest only structures. Modified terms are dependent upon the financial position and needs of the individual borrower. If the modification agreement is violated, the loan is managed by the Company’s credit administration group for resolution, which may result in foreclosure in the case of real estate. TDRs are generally classified as nonaccrual for a minimum period of six months and may qualify for return to accrual status once they have demonstrated performance with the restructured terms of the loan agreement.
Impaired Financing Receivable, Policy	First Financial individually reviews all impaired commercial loan relationships greater than $250,000 , as well as consumer loan TDRs greater than $100,000 , to determine if a specific allowance is necessary based on the borrower’s overall financial condition, resources and payment record, support from guarantors and the realizable value of any collateral. Specific allowances are based on discounted cash flows using the loan's initial effective interest rate or the fair value of the collateral for certain collateral dependent loans. Loans classified as nonaccrual, excluding purchased impaired loans, and loans modified as TDRs are considered impaired.
Loans and Leases Receivable, Real Estate Acquired Through Foreclosure, Policy	OREO is comprised of properties acquired by the Company primarily through the loan foreclosure or repossession process, or other resolution activity that results in partial or total satisfaction of problem loans.
Loans and Leases Receivable, Allowance for Loan Losses Policy	For each reporting period, management maintains the allowance for loan and lease losses at a level that it considers sufficient to absorb probable loan and lease losses inherent in the portfolio. Management determines the adequacy of the allowance based on historical loss experience as well as other significant factors such as composition of the portfolio, economic conditions, geographic footprint, the results of periodic internal and external evaluations of delinquent, nonaccrual and classified loans and any other adverse situations that may affect a specific borrower's ability to repay (including the timing of future payments). This evaluation is inherently subjective as it requires utilizing material estimates that may be susceptible to significant change. There were no material changes to First Financial's accounting policies or methodology related to the allowance for loan and lease losses during the first six months of 2015 . The allowance is increased by provision expense and decreased by actual charge-offs, net of recoveries of amounts previously charged-off. First Financial's policy is to charge-off all or a portion of a loan when, in management's opinion, it is unlikely to collect the principal amount owed in full either through payments from the borrower or from the liquidation of collateral.
Goodwill and Intangible Assets, Goodwill, Policy	Assets and liabilities acquired in a business combination are recorded at their estimated fair values as of the acquisition date. The excess cost of the acquisition over the fair value of net assets acquired is recorded as goodwill.
Goodwill and Intangible Assets, Goodwill Impairment Policy	Goodwill is not amortized, but is measured for impairment on an annual basis as of October 1 of each year, or whenever events or changes in circumstances indicate that the fair value of a reporting unit may be below its carrying value.
Goodwill and Intangible Assets, Policy	Other intangible assets primarily consists of core deposit intangibles. Core deposit intangibles represent the estimated fair value of acquired customer deposit relationships. Core deposit intangibles are recorded at their estimated fair value as of the acquisition date and are then amortized on an accelerated basis over their estimated useful lives.
Income Tax, Policy	First Financial regularly reviews its tax positions and establishes reserves for income tax-related uncertainties based on estimates of whether it is more likely than not that the tax uncertainty would be sustained upon challenge by the appropriate tax authorities, which would then result in additional taxes, penalties and interest due. These evaluations are inherently subjective as they require material estimates and may be susceptible to significant change.
Commitments and Contingencies, Policy	In the normal course of business, First Financial offers a variety of financial instruments with off-balance-sheet risk to assist clients in meeting their requirements for liquidity and credit enhancement. These financial instruments include standby letters of credit and outstanding commitments to extend credit. GAAP does not require these financial instruments to be recorded in the Consolidated Financial Statements. First Financial’s exposure to credit loss, in the event of nonperformance by the counterparty to the financial instrument for standby letters of credit and outstanding commitments to extend credit, is represented by the contractual amounts of those instruments. First Financial uses the same credit policies in issuing commitments and conditional obligations as it does for credit instruments recorded on the Consolidated Balance Sheets.
Fair Value of Financial Instruments, Policy	Fair Value Measurement The fair value framework as disclosed in the Fair Value Measurements and Disclosure Topic of FASB ASC Topic 825, Financial Instruments (Fair Value Topic) includes a hierarchy which focuses on prioritizing the inputs used in valuation techniques. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1), a lower priority to observable inputs other than quoted prices in active markets for identical assets and liabilities (Level 2) and the lowest priority to unobservable inputs (Level 3). When determining the fair value measurements for assets and liabilities, First Financial looks to active markets to price identical assets or liabilities whenever possible and classifies such items in Level 1. When identical assets and liabilities are not traded in active markets, First Financial looks to observable market data for similar assets and liabilities and classifies such items as Level 2. Certain assets and liabilities are not actively traded in observable markets and First Financial must use alternative techniques, based on unobservable inputs, to determine the fair value and classifies such items as Level 3. The level within the fair value hierarchy is based on the lowest level of input that is significant in the fair value measurement. The following methods, assumptions and valuation techniques were used by First Financial to measure different financial assets and liabilities at fair value and in estimating its fair value disclosures for financial instruments. Cash and short-term investments. The carrying amounts reported in the Consolidated Balance Sheets for cash and short-term investments, such as federal funds sold, approximated the fair value of those instruments. The Company classifies cash and short-term investments in Level 1 of the fair value hierarchy. Investment securities. Investment securities classified as trading and available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar investment securities. First Financial compiles prices from various sources who may apply such techniques as matrix pricing to determine the value of identical or similar investment securities (Level 2). Matrix pricing is a mathematical technique widely used in the banking industry to value investment securities without relying exclusively on quoted prices for the specific investment securities but rather relying on the investment securities’ relationship to other benchmark quoted investment securities. Any investment securities not valued based upon the methods above are considered Level 3. First Financial utilizes information provided by third-party pricing vendors to analyze the investment securities portfolio in accordance with the fair value hierarchy of the Fair Value Topic and reviews the pricing methodologies utilized by the pricing vendors to ensure that the fair value determination is consistent with the applicable accounting guidance. First Financial’s month-end pricing process includes a series of quality assurance activities where prices are compared to recent market conditions, historical prices and other independent pricing services. Further, the Company periodically validates the fair values of a sample of securities in the portfolio by comparing the fair values to prices from other independent sources for the same or similar securities. First Financial analyzes unusual or significant variances, conducts additional research with the pricing vendor, and if necessary, takes appropriate action based on its findings. The results of the quality assurance process are incorporated into the selection of pricing providers by the portfolio manager. Loans held for sale. Loans held for sale are carried at the lower of cost or fair value. These loans currently consist of one-to-four family residential real estate loans originated for sale to qualified third parties. Fair value is based on the contractual price to be received from these third parties, which is not materially different than cost due to the short duration between origination and sale (Level 2). As such, First Financial records any fair value adjustments on a nonrecurring basis. Gains and losses on the sale of loans are recorded as net gains from sales of loans within noninterest income in the Consolidated Statements of Income. Loans and leases. The fair value of commercial, commercial real estate, residential real estate and consumer loans were estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or repricing frequency. The Company classifies the estimated fair value of loans as Level 3 in the fair value hierarchy. Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreement will not be collected. Impaired loans are valued at the lower of cost or fair value for purposes of determining the appropriate amount of impairment to be allocated to the allowance for loan and lease losses. Fair value is generally measured based on the value of the collateral securing the loans. Collateral may be in the form of real estate or business assets including equipment, inventory and accounts receivable. The vast majority of the collateral is real estate. The value of real estate collateral is determined utilizing an income or market valuation approach based on an appraisal conducted by an independent, licensed third-party appraiser (Level 3). The value of business equipment is based upon an outside appraisal if deemed significant, or the net book value on the applicable borrower financial statements if not considered significant. Likewise, values for inventory and accounts receivable collateral are based on borrower financial statement balances or aging reports on a discounted basis as appropriate (Level 3). Impaired loans allocated to the allowance for loan and lease losses are measured at fair value on a nonrecurring basis. Any fair value adjustments are recorded in the period incurred as provision for loan and lease losses on the Consolidated Statements of Income. Fair values for purchased impaired loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate, term of loan and whether or not the loan was amortizing, and a discount rate reflecting the Company's assessment of risk inherent in the cash flow estimates. These loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. First Financial estimated the cash flows expected to be collected on these loans based upon the expected remaining life of the underlying loans, which includes the effects of estimated prepayments. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change. Fair values for acquired loans accounted for outside of FASB ASC Topic 310-30 were estimated by discounting the future cash flows using current interest rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or repricing frequency. The carrying amount of accrued interest approximates its fair value. The Company classifies the estimated fair value of covered loans as Level 3 in the fair value hierarchy. FDIC indemnification asset. Fair value of the FDIC indemnification asset was estimated using projected cash flows related to the loss sharing agreements based on expected reimbursements for losses and the applicable loss sharing percentages. The expected cash flows are discounted to reflect the uncertainty of the timing and receipt of the loss sharing reimbursement from the FDIC. These cash flow evaluations are inherently subjective as they require material estimates, all of which may be susceptible to significant change, and may be impacted by the relatively short remaining term of loss sharing coverage on covered commercial assets. The five year period of loss protection expired for the majority of First Financial's covered commercial loans and covered OREO effective October 1, 2014. The Company classifies the estimated fair value of the indemnification asset as Level 3 in the fair value hierarchy. Deposits. The fair value of demand deposits, savings accounts and certain money-market deposits was the amount payable on demand at the reporting date. The carrying amounts for variable-rate certificates of deposit approximated their fair values at the reporting date. The fair value of fixed-rate certificates of deposit was estimated using a discounted cash flow calculation which applies the interest rates currently offered for deposits of similar remaining maturities. The carrying amount of accrued interest approximates its fair value. The Company classifies the estimated fair value of deposit liabilities as Level 2 in the fair value hierarchy. Borrowings. The carrying amounts of federal funds purchased and securities sold under agreements to repurchase and other short-term borrowings approximate their fair values. The Company classifies the estimated fair value of short-term borrowings as Level 1 of the fair value hierarchy. The fair value of long-term debt is estimated using a discounted cash flow calculation which utilizes the interest rates currently offered for borrowings of similar remaining maturities. Third-party valuations are used for long-term debt with embedded options, such as call features. The Company classifies the estimated fair value of long-term debt as Level 2 in the fair value hierarchy. Commitments to extend credit and standby letters of credit. Pricing of these financial instruments is based on the credit quality and relationship, fees, interest rates, probability of funding and compensating balance and other covenants or requirements. Loan commitments generally have fixed expiration dates, are variable rate and contain termination and other clauses which provide for relief from funding in the event that there is a significant deterioration in the credit quality of the client. Many loan commitments are expected to expire without being drawn upon. The rates and terms of the commitments to extend credit and the standby letters of credit are competitive with those in First Financial’s market area. The carrying amounts are reasonable estimates of the fair value of these financial instruments. Carrying amounts, which are comprised of the unamortized fee income and, where necessary, reserves for any expected credit losses from these financial instruments, are immaterial. Derivatives. The fair values of derivative instruments are based primarily on a net present value calculation of the cash flows related to the interest rate swaps at the reporting date, using primarily observable market inputs such as interest rate yield curves. The discounted net present value calculated represents the cost to terminate the swap if First Financial should choose to do so. Additionally, First Financial utilizes a vendor-developed, proprietary model to value the credit risk component of both the derivative assets and liabilities. The credit valuation adjustment is recorded as an adjustment to the fair value of the derivative asset or liability on the reporting date. Derivative instruments are classified as Level 2 in the fair value hierarchy.
Other Contract-Mortgage
Derivatives, Methods of Accounting, Hedging Derivatives, Policy	First Financial enters into IRLCs and forward commitments for the future delivery of mortgage loans to third party investors, which are considered derivatives. When borrowers secure an IRLC with First Financial and the loan is intended to be sold, First Financial will enter into forward commitments for the future delivery of the loans to third party investors in order to hedge against the effect of changes in interest rates.
Credit Risk
Derivatives, Methods of Accounting, Hedging Derivatives, Policy	First Financial manages this market value credit risk through counterparty credit policies. These policies require the Company to maintain a total derivative notional position of less than 35% of assets, total credit exposure of less than 3% of capital and no single counterparty credit risk exposure greater than $20.0 million .
Fair Value Hedges
Derivatives, Methods of Accounting, Hedging Derivatives, Policy	First Financial utilizes interest rate swaps designated as fair value hedges as a means to offer commercial borrowers fixed rate funding while providing the Company with floating rate assets.
Cash Flow Hedges
Derivatives, Methods of Accounting, Hedging Derivatives, Policy	First Financial utilizes interest rate swaps designated as cash flow hedges to hedge against interest rate volatility on indexed floating rate deposits.
