FIRST FINANCIAL BANCORP. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
March 31, 2018
(Unaudited)
NOTE 1: BASIS OF PRESENTATION
The Consolidated Financial Statements of First Financial Bancorp., a financial holding company principally serving Ohio, Indiana and Kentucky, include the accounts and operations of First Financial and its wholly-owned subsidiary, First Financial Bank. All significant intercompany transactions and accounts have been eliminated in consolidation. Certain reclassifications of prior periods' amounts have been made to conform to current year presentation. Such reclassifications had no effect on net earnings.
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, 2017. 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, 2017 has been derived from the audited financial statements in the Company’s 2017 Form 10-K.
NOTE 2: RECENTLY ADOPTED AND ISSUED ACCOUNTING STANDARDS
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. For further detail, see Note 13 – Revenue Recognition.
In January 2016, the FASB issued an update (ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities) which requires entities to measure many equity investments at fair value and recognize changes in fair value in net income. This update does not apply to equity investments that result in consolidation, those accounted for under the equity method and certain others, and will eliminate use of the available for sale classification for equity securities while providing a new measurement alternative for equity investments that do not have readily determinable fair values and do not qualify for the net asset value practical expedient. This update also requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. The guidance in this ASU became effective in the first quarter of 2018 and did not have a material impact on the Consolidated Financial Statements. In accordance with the guidance, the Company measured the fair value of its financial instruments as of March 31, 2018 using an exit price notion. For further detail, see Note 15 – Fair Value Disclosures.
In February 2016, the FASB issued an update (ASU 2016-02, Leases) which requires lessees to record most leases on their balance sheet and recognize leasing expenses in the income statement. Operating leases, except for short-term leases that are subject to an accounting policy election, will be recorded on the balance sheet for lessees by establishing a lease liability and corresponding right-of-use asset. The guidance in this ASU will become effective for interim and annual reporting periods beginning after December 15, 2018, with early adoption permitted. Given operating leases outstanding as of March 31, 2018, First Financial does not expect this ASU to have a material impact on the income statement, but does anticipate an increase in the Company's assets and liabilities. Decisions to repurchase, modify or renew leases prior to the implementation date will impact this level of materiality.

Table of Contents
In June 2016, the FASB issued an update (ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments) which significantly changes how entities are required to measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. This update will replace the current incurred loss approach for estimating credit losses with an expected loss model for instruments measured at amortized cost, including loans and leases. Expected credit losses are required to be based on amortized cost and reflect losses expected over the remaining contractual life of the asset. Management is expected to consider any available information relevant to assessing the collectibility of contractual cash flows, such as information about past events, current conditions, voluntary prepayments and reasonable and supportable forecasts, when developing expected credit loss estimates.
In addition to the new framework for calculating the ALLL, this update requires allowances for available-for-sale debt securities rather than a reduction of the security's carrying amount under the current other-than-temporary impairment model. This update also simplifies the accounting model for purchased credit-impaired debt securities and loans and will require new and updated footnote disclosures.
The guidance in this ASU will become effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted for all entities for interim and annual reporting periods beginning after December 15, 2018. First Financial has formed an internal committee that is currently evaluating the impact of this update on its Consolidated Financial Statements.
In August 2016, the FASB issued an update (ASU 2016-15 Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments) which may change how an entity classifies certain cash receipts and cash payments on its statement of cash flows to reduce diversity in practice. The update also provides guidance on when an entity should separate cash flows and classify them into more than one class and when an entity should classify the aggregate of those cash flows into a single class based on the predominance principle. The guidance in this ASU became effective in the first quarter of 2018 and did not have a material impact on the Consolidated Financial Statements.
In January 2017, the FASB issued an update (ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment) which simplifies the subsequent measurement of goodwill by eliminating Step 2 from goodwill impairment testing. This update requires an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, with any loss recognized not to exceed the total amount of goodwill allocated to that reporting unit. Additionally, the update requires consideration of the income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable, and eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. First Financial early adopted the provisions set forth in this update in 2017. Adoption of this update did not have a material impact on First Financial's Consolidated Financial Statements.
In March 2017, the FASB issued an update (ASU 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of the Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost) which requires disaggregation of the service cost component from the other components of net benefit cost. This update also provides explicit guidance on how to present the service cost component and the other components of net benefit cost in the income statement and allows only the service cost component of net benefit cost to be eligible for capitalization. The guidance in this ASU became effective in the first quarter of 2018 and did not have a material impact on the Consolidated Financial Statements.
In March 2017, the FASB issued an update (ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities) which amends the amortization period for certain purchased callable debt securities held at a premium and shortens the amortization period for the premium to the earliest call date rather than as an adjustment of yield over the contractual life of the instrument. This update more closely aligns the amortization period of premiums and discounts to expectations incorporated in market pricing on the underlying securities, as in most cases, market participants price securities to the call date that produces the worst yield when the coupon is above current market rates (that is, the security is trading at a premium) and price securities to maturity when the coupon is below market rates (that is, the security is trading at a discount) in anticipation that the borrower will act in its economic best interest in an attempt to more closely align interest income recorded on bonds held at a premium or a discount with the economics of the underlying instrument. The guidance in this ASU will become effective for reporting periods, beginning after December 15, 2018, with early adoption permitted. First Financial is currently evaluating the impact of this update on its Consolidated Financial Statements.

Table of Contents
In May 2017, the FASB issued an update (ASU 2017-09, Compensation - Stock Compensation (Topic 718), Scope of Modification Accounting), which provides clarity and reduces the diversity in practice, cost and complexity when accounting for a change to the terms or conditions of a share-based payment award. The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718 clarifying that an entity will not apply modification accounting to a share-based payment award if the award's fair value (or calculated value or intrinsic value), vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. The guidance in this ASU became effective in the first quarter of 2018 and did not have a material impact on the Consolidated Financial Statements.
In August 2017, the FASB issued an update (ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities) to better align financial reporting for hedging activities with the economic objectives of those activities. This update aligns certain aspects of hedge documentation, effectiveness assessments, accounting and disclosures, and expands permissible hedge strategies as of the date of adoption. The guidance in this ASU will become effective for reporting periods beginning after December 15, 2018, with early adoption permitted, and will require a modified retrospective transition method with recognition of the cumulative effect of the change on the opening balance of each affected component of equity. Amended disclosures will be required prospectively. First Financial is currently evaluating the impact of this update on its Consolidated Financial Statements.
In February 2018, the FASB issued an update (ASU 2018-02, Income statement-Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income), which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminated the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. The amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, and the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not effected. The amendments in this update also require certain disclosures about stranded tax effects. The guidance in this ASU will become effective for reporting periods beginning after December 15, 2018, with early adoption permitted, and will be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. First Financial early adopted the provisions set forth in this update in the first quarter of 2018, and as a result, reclassified $4.9 million from accumulated other comprehensive income to retained earnings. There were no other income tax effects related to the Act that were reclassified as a result of the adoption of the accounting standard.
NOTE 3: INVESTMENTS
For the three months ended March 31, 2018, there were no sales of available-for-sale securities. For the three months ended March 31, 2017, proceeds on the sale of $22.2 million of available-for-sale securities resulted in gains of $0.5 million.
The following is a summary of held-to-maturity and available-for-sale investment securities as of March 31, 2018:

Gains and losses on debt securities are generally due to fluctuations in current market yields relative to the yields of the debt securities at their amortized cost. 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 March 31, 2018 or December 31, 2017.
As of March 31, 2018, the Company's investment securities portfolio consisted of 774 securities, of which 359 were in an unrealized loss position. As of December 31, 2017, the Company's investment securities portfolio consisted of 775 securities, of which 237 were in an unrealized loss position.

NOTE 4: LOANS AND LEASES
First Financial offers clients a variety of commercial and consumer loan and lease products with distinct interest rates and payment terms. Commercial loan categories include commercial and industrial, commercial real estate, construction real estate and lease financing. Consumer loan categories include residential real estate, home equity, installment and credit card.
Lending activities are primarily concentrated in states where the Bank operates banking centers (Ohio, Indiana and Kentucky). First Financial also offers two nationwide lending platforms, one that provides equipment and leasehold improvement financing for franchisees in the quick service and casual dining restaurant sector and another that provides loans accounts primarily to insurance agents and brokers that are secured by commissions and cash collateral.
Credit Quality. To facilitate the monitoring of credit quality for commercial loans, and for purposes of determining an appropriate ALLL, 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 highly questionable and improbable, on the basis of currently existing facts, conditions and values. 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 previously described are derived from standard regulatory rating definitions and 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 classified as nonperforming. Purchased impaired loans are not classified as nonperforming assets as the loans are considered to be performing under FASB ASC Topic 310-30.
Commercial and consumer credit exposure by risk attribute was as follows:

Nonaccrual. 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. When a loan is classified as nonaccrual, the accrual of interest income is discontinued and previously accrued but unpaid interest is reversed. Any payments received while a loan is on nonaccrual status are applied as a reduction to the carrying value of the loan. A loan classified as nonaccrual 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 provision for loan and lease losses or prospective yield adjustments.
Troubled Debt Restructurings. A loan modification is considered a TDR when the borrower is experiencing financial difficulty and 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 considers repayment performance as an indication of the effectiveness of the Company's loan modifications. Borrowers 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.

There were no TDRs for which there was a payment default during the period that occurred within twelve months of the loan modification for the three months ended March 31, 2018 or March 31, 2017.

First Financial individually reviews all impaired commercial loan relationships, as well as consumer loan TDRs, greater than $250,000, to determine if a specific allowance is necessary based on the borrower’s overall financial condition, 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.

FDIC indemnification asset. The FDIC indemnification asset results from the loss sharing agreements entered into in conjunction with First Financial's FDIC-assisted transactions, and represents expected reimbursements from the FDIC for losses on covered assets.
In the first quarter of 2018, First Financial received a settlement payment from the FDIC finalizing the termination of its loss sharing agreements. Therefore, First Financial had no FDIC indemnification asset balance as of March 31, 2018. All future recoveries, gains, losses and expenses related to assets previously covered under loss sharing agreements will be fully recognized by First Financial. As of December 31, 2017, the FDIC indemnification asset balance was $1.9 million.
NOTE 5: ALLOWANCE FOR LOAN AND LEASE LOSSES
Loans and leases. Management maintains the ALLL at a level that it considers sufficient to absorb probable incurred loan and lease losses inherent in the portfolio. Management determines the adequacy of the ALLL 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.
The ALLL is increased by provision expense and decreased by 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.

NOTE 6: 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. First Financial had goodwill of $204.1 million as of March 31, 2018 and December 31, 2017, respectively, and recorded no additional goodwill during 2018 or 2017.
Goodwill is evaluated 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, 2017 and no impairment was indicated. As of March 31, 2018, no events or changes in circumstances indicated that the fair value of a reporting unit was below its carrying value.
Other intangible assets. As of March 31, 2018 and December 31, 2017, First Financial had $5.0 million and $5.3 million, respectively, of other intangible assets, which primarily consist of core deposit intangibles and are included in Goodwill and other intangibles in the Consolidated Balance Sheets. Core deposit intangibles represent the estimated fair value of acquired customer deposit relationships. Core deposit intangibles are recorded at fair value on the date of acquisition and are then amortized on an accelerated basis over their estimated useful lives. Core deposit intangibles were $3.1 million and $3.3 million as of March 31, 2018 and December 31, 2017, respectively. First Financial's core deposit intangibles have an estimated weighted average remaining life of 3.6 years. Amortization expense recognized on intangible assets for the three months ended March 31, 2018 and 2017 was $0.3 million for each period.
NOTE 7: BORROWINGS
Short-term borrowings on the Consolidated Balance Sheets include repurchase agreements utilized for corporate sweep accounts with cash management account agreements in place, overnight advances from the FHLB and a short-term line of credit. All repurchase agreements are subject to terms and conditions of repurchase/security agreements between the Bank and the client. To secure its liability to the client, the Bank is authorized to sell or repurchase U.S. Treasury, government agency and mortgage-backed securities.
First Financial had $601.6 million in short-term borrowings with the FHLB at March 31, 2018 and $742.3 million as of December 31, 2017. These short-term borrowings are used to manage normal liquidity needs and support the Company's asset and liability management strategies.
First Financial has a $15.0 million short-term credit facility with an unaffiliated bank that matures on May 29, 2018. 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 common stock and the payment of dividends to shareholders. As of March 31, 2018 and December 31, 2017, 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 facility as of March 31, 2018 and December 31, 2017.
In 2015, First Financial issued $120.0 million of subordinated notes, which have a fixed interest rate of 5.125% payable semiannually and mature on August 25, 2025. These notes are not redeemable by the Company, or callable by the holders of the notes prior to maturity. The subordinated notes are treated as Tier 2 capital for regulatory capital purposes and are included in Long-term debt on the Consolidated Balance Sheets.
Long-term debt also includes $50.2 million and $0.2 million of FHLB long-term advances as of March 31, 2018 and December 31, 2017, respectively. The $50.0 million of additional FHLB long-term advance matures in 2020 with a fixed rate of 2.63%. These instruments are primarily utilized to reduce overnight liquidity risk and to mitigate interest rate sensitivity on the Consolidated Balance Sheets.

NOTE 9: DERIVATIVES
First Financial uses certain 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. First Financial may also utilize interest rate swaps to manage the interest rate risk profile of the Company.
Interest rate payments are exchanged with counterparties based on the notional amount established in the interest rate agreement. 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 market value credit risk through counterparty credit policies, which 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 March 31, 2018, the Company had a total counterparty notional amount outstanding of $908.6 million, spread among fourteen counterparties, with an outstanding asset from these contracts of $10.4 million. At December 31, 2017, the Company had a total counterparty notional amount outstanding of $837.5 million, spread among thirteen counterparties, with an outstanding liability from these contracts of $1.3 million.
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 ALLL 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.

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.

Credit Derivatives. In conjunction with participating interests in commercial loans, First Financial periodically enters into risk participation agreements with 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 $95.6 million as of March 31, 2018 and $95.9 million as of December 31, 2017. The fair value of these agreements is recorded in Accrued interest and other liabilities on the Consolidated Balance Sheets.
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 impacting IRLCs and loans held for sale. At March 31, 2018, the notional amount of the IRLCs was $13.0 million and the notional amount of forward commitments was $10.1 million. As of December 31, 2017, the notional amount of IRLCs was $12.3 million and the notional amount of forward

commitments was $15.4 million. The fair value of these agreements was recorded on the Consolidated Balance Sheets in Accrued interest and other assets and was $0.1 million at both March 31, 2018 and December 31, 2017.
NOTE 10: COMMITMENTS AND CONTINGENCIES
First Financial offers a variety of financial instruments including standby letters of credit and outstanding commitments to extend credit to assist clients in meeting their requirement for liquidity and credit enhancement. GAAP does not require these financial instruments to be recorded in the Consolidated Financial Statements.
First Financial utilizes the same credit policies in issuing commitments and conditional obligations as it does for credit instruments recorded on the Consolidated Balance Sheets. First Financial’s exposure to credit loss in the event of nonperformance by the counterparty is represented by the contractual amounts of those instruments. First Financial utilizes the ALLL methodology to maintain a reserve that it considers sufficient to absorb probable incurred losses inherent in 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 $2.0 billion and $2.1 billion at March 31, 2018 and December 31, 2017, respectively. As of March 31, 2018, loan commitments with a fixed interest rate totaled $75.6 million while commitments with variable interest rates totaled $2.0 billion. At December 31, 2017, loan commitments with a fixed interest rate totaled $44.3 million while commitments with variable interest rates totaled $2.0 billion. The fixed rate loan commitments have interest rates ranging from 0.00% to 21.00% and maturities ranging from less than 1 year to 30 years.
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 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 aggregating $25.0 million and $25.3 million at March 31, 2018 and December 31, 2017, respectively. Management conducts regular reviews of these instruments on an individual client basis.
Investments in affordable housing tax credits. First Financial has made investments in certain qualified affordable housing tax credits. These credits are an indirect federal subsidy that provide tax incentives to encourage investment in the development, acquisition and rehabilitation of affordable rental housing, and allow 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 the unavailability or recapture of the tax credits and other tax benefits. Investments in affordable housing projects are accounted for under the proportional amortization method and are included in Accrued interest and other assets in the Consolidated Balance Sheets. First Financial's affordable housing commitments totaled $33.2 million and $35.9 million as of March 31, 2018 and December 31, 2017, respectively. The Company recognized tax credits of $1.1 million and $0.8 million for the three months ended March 31, 2018 and 2017, respectively. The Company recognized amortization expense which was included in income tax expense of $1.3 million and $1.0 million for the three months ended March 31, 2018 and 2017, respectively. First Financial had no affordable housing contingent commitments as of March 31, 2018 or December 31, 2017.
Investments in historic tax credits. First Financial has noncontrolling financial investments in private investment funds and partnerships which are not consolidated. These investments may generate a return through the realization of federal and state income tax credits, as well as other tax benefits, such as tax deductions from net operating losses of the investments over a period of time. Investments in historic tax credits are accounted for under the equity method of accounting and are carried in Accrued interest and other assets on the Consolidated Balance Sheets. The Company’s recorded investment in these entities was approximately $2.9 million at March 31, 2018 and $3.0 million at December 31, 2017. The maximum exposure to loss related to these investments was $2.9 million at March 31, 2018 and $3.0 million at December 31, 2017, representing the Company’s investment balance and its unfunded commitments to invest additional amounts. Investments in historic tax credits resulted in $0.1 million of tax credits for each of the three months ended March 31, 2018 and 2017, 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 March 31, 2018. 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. First Financial had no reserves related to litigation matters as of March 31, 2018 or December 31, 2017.
NOTE 11: INCOME TAXES
For the first quarter 2018, income tax expense was $7.7 million, resulting in an effective tax rate of 20.1% compared with income tax expense of $10.5 million and an effective tax rate of 30.0% for the comparable period in 2017. ASU 2016-09, Compensation-Stock Compensation Improvements to Employee Share-Based Payment Accounting, requires the recognition of the income tax effects of share-based awards through the income statement as a component of income tax expense. First Financial recorded a $0.4 million and $1.1 million tax benefit as a result of share awards vesting and exercised during the first quarters of 2018 and 2017, respectively.
On December 22, 2017, the Tax Cuts and Jobs Act was signed into law. As a result, First Financial valued its deferred tax assets and liabilities as well as its investments in affordable housing projects utilizing a 21% federal rate during the first quarter of 2018 compared to a 35% rate in the first quarter of 2017.
At both March 31, 2018 and December 31, 2017, First Financial had $2.9 million of unrecognized tax benefits, as determined in FASB ASC Topic 740-10, Income Taxes that, if recognized, would favorably affect the effective income tax rate in future periods. The unrecognized tax benefits relate to state income tax exposures from taking tax positions where the Company believes it is likely that, upon examination, a state may take a position contrary to the position taken by the Company. The Company believes that resolution regarding our uncertain tax positions is reasonably possible within the next twelve months and could result in full, partial or no recognition of the benefit. First Financial recognizes interest accrued related to unrecognized tax benefits and penalties as income tax expense. At March 31, 2018 and December 31, 2017, the Company had no interest or penalties recorded.
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 2014 have been closed and are no longer subject to U.S. federal income tax examinations. Tax years 2014 through 2017 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 2011. Tax years 2011 through 2017 remain open to state and local examination in various jurisdictions.
NOTE 12: EMPLOYEE BENEFIT PLANS
First Financial sponsors a non-contributory defined benefit pension plan covering substantially all employees and uses a December 31 measurement date for the plan. Plan assets were primarily invested in fixed income and publicly traded equity mutual funds. The pension plan does not directly own any shares of First Financial common stock or any other First Financial security or product.
First Financial made no cash contributions to fund the pension plan during the three months ended March 31, 2018, or the year ended December 31, 2017, and does not expect to make cash contributions to the plan through the remainder of 2018. As a result of the plan’s actuarial projections, First Financial recorded income of 0.2 million and 0.3 million for the three months ended March 31, 2018 and 2017, respectively.

NOTE 13: REVENUE RECOGNITION
On January 1, 2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers using the modified retrospective method applied to all contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the guidance set forth in this update while prior period amounts continue to be reported in accordance with legacy GAAP. Adoption of this update did not result in a change to the accounting for any of the in-scope revenue streams. As such, no cumulative effect adjustment to retained earnings was recorded.
The majority of the Company's revenues come from interest income and other sources, including loans, leases, securities and derivatives, that are outside the scope of this guidance. The Company's services that fall within the scope of this ASU are presented within Noninterest income and are recognized as revenue as the Company satisfies its obligation to the customer. Services within the scope of this guidance include service charges on deposits, wealth management fees, bankcard income, investment brokerage fees and the sale of OREO.
Service charges on deposit accounts. The Company earns fees from its deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Similarly, overdraft fees are recognized at the point in time that the overdraft occurs as this corresponds with the Company's performance obligation. Service charges on deposit accounts are withdrawn from the customer's account balance.
Trust and wealth management fees. Trust and wealth management fees are primarily asset-based, but can also include flat fees based upon a specific service rendered, such as tax preparation services. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fees. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and wealth management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized as incurred.
Bankcard income. The Company earns interchange fees from cardholder transactions conducted through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized, concurrent with the transaction processing services provided to the cardholder. Interchange income is presented on the Consolidated Statements of Income net of expenses. Gross interchange income for the first quarter of 2018 was $5.4 million, which was partially offset by $2.0 million of expenses within Noninterest income.
Gains/losses on sale of OREO. The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of the executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectibility of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant component is present.

Other. Other noninterest income consists of other recurring revenue streams such as transaction fees, safe deposit rental income, insurance commissions, merchant referral income and brokerage revenue. Transaction fees primarily include check printing sales commissions, collection fees, and wire transfer fees which arise from in-branch transactions. Safe deposit rental income arises from services charged to the customer on an annual basis and recognized upon receipt of payment. Insurance commissions are agent commissions earned by the Company and earned upon the effective date of the bound coverage. Merchant referral income is associated with a program whereby the Company receives a share of processing revenue that is generated from clients that were referred by First Financial to the service provider. Revenue is recognized at the point in time when the transaction occurs. Brokerage revenue represents fees from investment brokerage services provided to customers by a third party provider. The Company receives commissions from the third-party service provider on a monthly basis based upon customer activity for the month. The fees are recognized monthly and a receivable is recorded until commissions are paid the following month. Because the Company (i) acts as an agent in arranging the relationship between the customer and the third-party service provider and (ii) does not control the services rendered to the customers, investment brokerage fees are presented net of related costs.

Warrants to purchase 101,808 and 112,233 shares of the Company's common stock were outstanding as of March 31, 2018 and 2017, respectively. These warrants, each representing the right to purchase one share of common stock, no par value per share, have an exercise price of $12.11 and expire on December 23, 2018.
Stock options and warrants with exercise prices 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. Using the end of period price of the Company's common shares, there were no antidilutive options at March 31, 2018 and March 31, 2017.

NOTE 15: FAIR VALUE DISCLOSURES
Fair Value Measurement
The fair value framework as disclosed in the 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 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:

N/A = Not applicable
The methods utilized to estimate the fair value of financial instruments at December 31, 2017 did not necessarily represent an exit price. In accordance with our adoption of ASU 2016-01 in 2018, the methods utilized to measure the fair value of financial instruments at March 31, 2018 represent an approximation of exit price, however, an actual exit price may differ.
The following methods, assumptions and valuation techniques were used by First Financial to measure different financial assets and liabilities at fair value on a recurring or nonrecurring basis.
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 previously described are considered Level 3.
First Financial utilizes values provided by third-party pricing vendors to price 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 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 value 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.
Impaired loans. The fair value of impaired loans are specifically reviewed for purposes of determining the appropriate amount of impairment to be allocated to the ALLL. 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 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 on an outside appraisal, if deemed significant, or the net book value on the applicable borrower financial statements. 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 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.

Table of Contents
OREO. Assets acquired through loan foreclosure are recorded at fair value less costs to sell, with any difference between the fair value of the property and the carrying value of the loan recorded as a charge-off. If the fair value is higher than the carrying amount of the loan, the excess is recognized first as a recovery and then as noninterest income. Subsequent declines in value are reported as adjustments to the carrying amount and are recorded in noninterest expense. The carrying value of OREO is not re-measured to fair value on a recurring basis, but is subject to fair value adjustments when the carrying value differs from the fair value, less estimated selling costs. Fair value is based on recent real estate appraisals and is updated at least annually. The Company classifies OREO in level 3 of the fair value hierarchy.
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 which represents the cost to terminate the swap if First Financial should choose to do so. Additionally, First Financial utilizes an internally-developed model to value the credit risk component of derivative assets and liabilities, which 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 financial assets and liabilities measured at fair value on a recurring basis in the consolidated financial statements were as follows:

SUMMARY
First Financial is an $8.9 billion financial holding company headquartered in Cincinnati, Ohio, that operates primarily in Ohio, Indiana and Kentucky through its subsidiaries. These subsidiaries include the Bank, which is an Ohio-chartered commercial bank, operating 95 banking centers and 118 ATMs at March 31, 2018. First Financial provides banking and financial services products to business and retail clients through its six lines of business: Commercial and Private Banking, Retail Banking, Mortgage Banking, Wealth Management, Investment Commercial Real Estate and Commercial Finance. Commercial Finance provides equipment and leasehold improvement financing for franchisees in the quick service and casual dining restaurant sector and commission-based financing, primarily to insurance agents and brokers, throughout the United States. Wealth management had $2.6 billion in assets under management as of March 31, 2018 and provides wealth planning, portfolio management, trust and estate, brokerage and retirement plan services.
MARKET STRATEGY AND BUSINESS COMBINATIONS
First Financial’s goal is to develop a competitive advantage by utilizing a local market focus to provide a superior level of service and build long-term relationships with clients to help them reach greater levels of financial success. First Financial serves a combination of metropolitan and non-metropolitan markets in Ohio, Indiana and Kentucky through its full-service banking centers, and provides financing to franchise owners and clients within the financial services industry throughout the United States. First Financial’s market selection process includes a number of factors, but markets are primarily chosen for their potential for growth and long-term profitability. First Financial intends to concentrate plans for future growth and capital investment within its current metropolitan markets, and will continue to evaluate additional growth opportunities in metropolitan markets located within, or in close proximity to, the Company's current geographic footprint. Additionally, First Financial may assess strategic acquisitions that provide product line extensions or additional industry verticals that compliment our existing business. First Financial's investment in non-metropolitan markets is an important part of the Bank's core funding base and has historically provided stable, low-cost funding sources.
On April 1, 2018, the Company completed its acquisition of MainSource Financial Group, Inc. and its banking subsidiary, MainSource Bank. Under the terms of the merger agreement, shareholders of MainSource received 1.3875 common shares of First Financial common stock for each share of MainSource common stock. Including outstanding options and warrants on MainSource common stock, total purchase consideration was $1.0 billion. The final fair values of assets and liabilities are not yet available. As of March 31, 2018, MainSource had total assets of $4.6 billion, gross loans of $3.0 billion and total deposits of $3.4 billion. The Company anticipates recording goodwill and core deposit intangibles with this acquisition. The merger positions the combined company to better serve the complementary geographies of Ohio, Indiana and Kentucky, and creates a higher performing bank with greater scale and capabilities.
OVERVIEW OF OPERATIONS
First quarter 2018 net income was $30.5 million and earnings per diluted common share were $0.49. This compares with first quarter 2017 net income of $24.4 million and earnings per diluted common share of $0.39.
Return on average assets for the first quarter 2018 was 1.40% compared to 1.18% for the same period in 2017 and return on average shareholders’ equity for the first quarter 2018 was 13.31% compared to 11.36% for the first quarter 2017.
A discussion of First Financial's results of operations for the three months ended March 31, 2018 follows.

Table of Contents
NET INTEREST INCOME
Net interest income, First Financial’s principal source of income, is the excess of interest received from earning assets, including loan-related fees, less interest paid on interest-bearing liabilities. The amount of net interest income is determined by the volume and mix of earning assets, the rates earned on these earning assets and the volume, mix and rates paid for the deposits and borrowed money that support the earning assets.
For analytical purposes, net interest income is also presented in the table that follows, adjusted to a tax equivalent basis assuming a 21% marginal tax rate for 2018 and a 35% marginal tax rate for 2017. Net interest income is presented on a tax equivalent basis to consistently reflect income from tax-exempt assets, such as municipal loans and investments, in order to facilitate a comparison between taxable and tax-exempt amounts. Management believes that it is a standard practice in the banking industry to present net interest margin and net interest income on a fully tax equivalent basis as these measures provide useful information to make peer comparisons.

Net interest margin (1) | 3.80 | % |  | 3.63 | %
Net interest margin (fully tax equivalent) (1) | 3.84 | % |  | 3.70 | %

(1) Calculated using annualized net interest income divided by average earning assets.
Net interest income for the first quarter 2018 was $75.8 million, and increased $6.9 million, or 10.0%, from first quarter 2017 net interest income of $68.9 million. The increase in net interest income for the first quarter 2018 as compared to the same period in 2017 was primarily driven by an $11.5 million, or 14.6%, increase in interest income, which was partially offset by a $4.6 million, or 46.9%, increase in interest expense. Net interest income on a fully tax equivalent basis for the first quarter 2018 was $76.5 million compared to $70.2 million for the first quarter 2017.
Net interest margin on a fully tax equivalent basis increased 14 bps to 3.84% for the first quarter 2018 compared to 3.70% for the comparable quarter in 2017. The increase in net interest margin was driven by higher earning asset yields, which more than offset fewer loan fees, a lower tax equivalent adjustment and higher funding costs resulting from rising rates and shifts in funding mix during the quarter.
Higher interest income resulted from an increase in average earning assets from $7.7 billion in the first quarter 2017 to $8.1 billion in the first quarter 2018, as well as an increase in the yield on earning assets over those same periods from 4.15% to 4.53%, respectively. The increase in average earning assets was due to an increase in average loan balances of $270.0 million, or 4.7%, in the first quarter 2018 compared to the first quarter 2017, due to strong organic loan growth. Average investment securities balances also increased $136.1 million, or 7.1% in the first quarter 2018 compared to the first quarter 2017. The yield on earning assets was impacted by higher interest earned on loans and investment securities, reflecting recent increases in interest rates and slower investment prepayment speeds.
Interest expense increased as a result of higher average interest-bearing deposit balances, as well as higher rates paid on deposits during the period. Average interest-bearing deposits increased $390.0 million, or 7.9%, from the first quarter 2017 as a result of strong deposit generation efforts in recent quarters. Rising interest rates and an increase in higher cost deposits in recent periods contributed to a 21 bp increase in deposit costs from 57 bps for the first quarter 2017 to 78 bps for the first quarter 2018.

NONINTEREST INCOME
First quarter 2018 noninterest income was $16.9 million, decreasing $0.4 million, or 2.5%, from $17.4 million in the first quarter 2017. This slight decrease was due primarily to an $0.8 million, or 26.5%, decrease in other noninterest income, a $0.6 million, or 51.6%, decrease in net gains from sales of loans and a $0.5 million decrease in net gains on sales of investment securities, which were partially offset by a $0.7 million, or 59.3% increase in client derivative fees and a $0.4 million, or 8.5%, increase in deposit service charges.
The decrease in other noninterest income from $3.0 million during the first quarter 2017 to $2.2 million for the first quarter 2018 was primarily related to a $0.9 million decline in income from limited partnership investments. Net gains from sales of loans declined from $1.2 million in the first quarter 2017 to $0.6 million in the first quarter 2018 as higher interest rates and tight housing supply resulted in lower sales volume during the period. There were no securities sales during the first quarter 2018.
Higher client credit derivative fees in the first quarter of 2018 reflect strong loan demand, while the increase in deposit service charges was the result of deposit growth in 2018.
NONINTEREST EXPENSE
First quarter 2018 noninterest expense was $52.3 million compared with $51.0 million for the first quarter 2017. The $1.2 million, or 2.4%, increase from the comparable quarter in 2017 was primarily attributable to a $0.9 million, or 17.7%, increase in other noninterest expense, a $0.4 million, or 25.0%, increase in professional services and a $0.3 million, or 57.1% increase in marketing expenses, partially offset by a $0.6 million, or 2.0%, decline in salaries and employee benefits.
Higher other noninterest expenses during the first quarter 2018 were primarily driven by expenses related to the termination of the Company's FDIC loss sharing agreements. Elevated professional services were largely the result of merger-related expenses, while increased marketing expenses were related to the timing of various projects during the quarter. Lower salaries and benefits resulted from fewer employees and lower health care costs, which more than offset higher incentive compensation during the period.

INCOME TAXES
Income tax expense was $7.7 million for the first quarter of 2018, resulting in an effective tax rate of 20.1% compared to $10.5 million and 30.0% for the comparable period in 2017. The lower effective tax rate during the first three months of 2018 related primarily to the Tax Cuts and Jobs Act which lowered the Company's statutory federal tax rate from 35% to 21% effective January 1, 2018.
While the Company's effective tax rate may fluctuate from quarter to quarter due to tax jurisdiction changes, the level of tax-enhanced assets and tax credit investments, the full year effective tax rate for 2018 is expected to be approximately 19.5%.
LOANS
Loans, excluding loans held for sale, totaled $6.1 billion as of March 31, 2018, and increased $88.8 million, or 6.0% on an annualized basis, compared to December 31, 2017. The increase in loan balances from December 31, 2017 was the result of the Company's sales efforts, expanded presence in key metropolitan markets and investments in a diversified product suite. Higher loan balances at March 31, 2018 were driven by a $54.0 million, or 2.2%, increase in CRE loans, a $31.0 million, or 1.6%, increase in C&I loans and a $26.9 million, or 5.8%, increase in construction real estate loans during the period.
First quarter 2018 average loans, excluding loans held for sale, increased $278.9 million, or 4.9%, from the first quarter 2017. The increase in average loans, excluding loans held for sale, was driven by a $114.9 million, or 6.4%, increase in C&I loans and a $69.9 million, or 16.9%, increase in construction real estate loans. Increases in average loan balances were attributable to strong organic loan growth in recent periods in addition to funding of prior period commitments.
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 its 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. First Financial had purchased impaired loans totaling $98.7 million and $105.0 million, at March 31, 2018 and December 31, 2017, respectively. These balances exclude contractual interest not yet accrued.
In the first quarter of 2018, First Financial received a settlement payment from the FDIC finalizing the termination of it loss sharing agreements. Therefore, First Financial had no FDIC indemnification asset balance as of March 31, 2018. All future recoveries, gains, losses and expenses related to assets previously covered under loss sharing agreements will be fully recognized by First Financial. As of December 31, 2017, the FDIC indemnification asset balance was $1.9 million.
ASSET QUALITY
Nonperforming assets consist of nonaccrual loans, accruing TDRs (collectively, nonperforming loans) and OREO. 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 a borrower's continued failure to adhere to contractual payment terms, coupled with other pertinent factors. When a loan is classified as nonaccrual, the accrual of interest income is discontinued and previously accrued but unpaid interest is reversed. 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 provision for loan and lease losses or prospective yield adjustments.
Nonperforming assets increased $1.9 million, or 4.2%, to $46.3 million at March 31, 2018 from $44.4 million as of December 31, 2017, due to a $6.2 million, or 25.7%, increase in nonaccrual balances, which was partially offset by a $1.7 million, or 61.7%, decrease in OREO balances during the period. Higher nonperforming loans at March 31, 2018 were primarily driven by a single commercial relationship downgraded to nonaccrual status, which offset the Company's resolution efforts during the period.
Loans are classified as TDRs when borrowers are experiencing financial difficulties and concessions are made by the Company that would not otherwise be considered for a borrower with similar credit characteristics. 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. TDRs totaled $21.0 million at March 31, 2018, which is a $3.0 million, or 12.4%, decrease from $23.9 million at December 31, 2017.
Classified assets, which are defined by the Company as nonperforming assets plus performing loans internally rated substandard or worse, increased $0.3 million to $87.6 million as of March 31, 2018 compared to $87.3 million at December 31, 2017.

INVESTMENTS
First Financial's investment portfolio totaled $2.0 billion, or 23.0% of total assets at March 31, 2018 and $2.1 billion, or 23.1% of total assets, at December 31, 2017. Securities available-for-sale totaled $1.4 billion at March 31, 2018 and $1.3 billion at December 31, 2017, while held-to-maturity securities totaled $633.7 million at March 31, 2018 and $654.0 million at December 31, 2017.

Table of Contents
The Company's investment portfolio decreased $10.4 million, or 1.0%, during the first three months of 2018 while the duration of the investment portfolio was 3.3 years as of March 31, 2018 and 2.9 years as of December 31, 2017.
The Company invests in certain securities whose realization is dependent on future principal and interest repayments and thus carry credit risk. First Financial performs a detailed pre-purchase collateral and structural analysis on these securities and strategically invests in asset classes in which First Financial has expertise and experience, as well as a senior position in the capital structure. First Financial continuously monitors credit risk and geographic concentration risk in its evaluation of market opportunities that enhance the overall performance of the portfolio.
First Financial recorded a $10.1 million unrealized after-tax loss on the investment portfolio as a component of equity in accumulated other comprehensive income at March 31, 2018. The total unrealized loss on the investment portfolio increased $9.9 million from $0.2 million at December 31, 2017.
First Financial will continue to monitor loan and deposit demand, as well as balance sheet composition, capital sensitivity and the interest rate environment as it manages investment strategies in future periods.
DEPOSITS AND FUNDING
Total deposits as of March 31, 2018 were $7.0 billion, representing an increase of $115.5 million, or 1.7%, compared to December 31, 2017, as total time deposits increased $228.2 million, or 17.3%, while total savings deposits declined $12.2 million, or 0.5% and total interest-bearing demand deposits decreased $11.1 million, or 0.8%.
Non-time deposit balances totaled $5.5 billion as of March 31, 2018, decreasing $112.7 million, or 2.0%, compared to December 31, 2017. Time deposit balances increased as a result of higher brokered CD balances, which the Company periodically utilizes as a lower cost alternative to short and long-term borrowings.
Average deposits increased $461.4 million, or 7.2%, to $6.9 billion at March 31, 2018 from $6.4 billion at March 31, 2017 due to a $232.8 million, or 18.9%, increase in average time deposits and a $226.0 million, or 10.2%, increase in average savings deposits, which were partially offset by a $71.5 million, or 4.8%, decline in average non interest-bearing deposits. Higher average deposit balances resulted from strong organic deposit generation efforts, including significant growth in money market deposits in light of rising interest rates.
Borrowed funds decreased to $828.0 million at March 31, 2018 from $934.2 million at December 31, 2017 primarily resulting from the Company's funding needs and the cyclical nature of public fund deposits. First Financial utilizes short-term borrowings and longer-term advances from the FHLB as wholesale funding sources. First Financial had $601.6 million in short-term borrowings with the FHLB at March 31, 2018 and $742.3 million as of December 31, 2017. In addition to FHLB borrowings, short term borrowings included repurchase agreements of $56.7 million and $72.3 million at March 31, 2018 and December 31, 2017, respectively.
Total long-term debt was $169.7 million and $119.7 million on March 31, 2018 and December 31, 2017, respectively and consists primarily of subordinated notes, which have a fixed interest rate of 5.125% payable semiannually, and mature on August 25, 2025. These notes are not redeemable by the Company or callable by the holders of the notes prior to maturity and are treated as Tier 2 capital for regulatory capital purposes. As of March 31, 2018 and December 31, 2017, outstanding subordinated debt totaled $118.7 million and $118.6 million, respectively, which included prepaid debt issuance costs of $1.3 million and $1.4 million as of March 31, 2018 and December 31, 2017, respectively. Long-term debt also included FHLB long-term advances, which increased to $50.2 million at March 31, 2018 from $0.2 million as of December 31, 2017, as the Company implemented funding strategies to manage liquidity and interest rate risk. In addition, First Financial had an interest-free $0.8 million capital loan outstanding with a municipality at March 31, 2018 and December 31, 2017, which was included in long-term debt. First Financial's total remaining borrowing capacity from the FHLB was $724.5 million at March 31, 2018.
LIQUIDITY
Liquidity management is the process by which First Financial manages the continuing flow of funds necessary to meet its financial commitments on a timely basis and at a reasonable cost. These funding commitments include withdrawals by depositors, credit commitments to borrowers, shareholder dividends, share repurchases, operating expenses and capital expenditures. Liquidity is derived primarily from deposit growth, principal and interest payments on loans and investment securities, maturing loans and investment securities, access to wholesale funding sources and collateralized borrowings.

Table of Contents
First Financial’s most stable source of liability-funded liquidity for both long and short-term needs is deposit growth and retention of the core deposit base. In addition to core deposit funding, First Financial also utilizes a variety of other short and long-term funding sources, which include subordinated notes, longer-term advances from the FHLB and its short-term line of credit.
Both First Financial and the Bank received investment grade credit ratings from Kroll Bond Rating Agency, Inc, an independent rating agency. These credit ratings impact the cost and availability of financing to First Financial, and a downgrade to these credit ratings could affect First Financial's or the Bank’s ability to access the credit markets, and potentially increase borrowing costs, negatively impacting financial condition and liquidity. Key factors in maintaining high credit ratings include consistent and diverse earnings, strong credit quality and capital ratios, varied funding sources and disciplined liquidity monitoring procedures. The ratings of First Financial and the Bank at March 31, 2018 were as follows:

| First Financial Bancorp | First Financial Bank
Senior Unsecured Debt | BBB+ | A-
Subordinated Debt | BBB | A-
Short-Term Debt | K2 | BBB+
Deposit | N/A | K2
Short-Term Deposit | N/A | K2

For ease of borrowing execution, First Financial utilizes a blanket collateral agreement with the FHLB. First Financial pledged $3.5 billion of certain eligible residential, commercial and farm real estate loans, home equity lines of credit and government, agency and CMBS securities as collateral for borrowings from the FHLB as of March 31, 2018.
First Financial maintains a short-term credit facility with an unaffiliated bank for $15.0 million that matures on May 29, 2018. 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 March 31, 2018 and December 31, 2017, 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 March 31, 2018 and December 31, 2017.
First Financial's principal source of asset-funded liquidity is marketable investment securities, particularly those of shorter maturities. The market value of investment securities classified as available-for-sale totaled $1.4 billion and $1.3 billion at March 31, 2018 and December 31, 2017, respectively. Securities classified as held-to-maturity that are maturing within a short period of time are an additional source of liquidity and totaled $19.8 million and $21.8 million at March 31, 2018 and December 31, 2017, respectively. Other sources of liquidity include cash and due from banks, interest-bearing deposits with other banks and loans maturing within one year.
At March 31, 2018, in addition to liquidity on hand of $126.8 million, First Financial had unused and available overnight wholesale funding of $2.3 billion, or 26.3% of total assets, to fund loan and deposit activities, in addition to other general corporate requirements.
Certain restrictions exist regarding the ability of First Financial’s subsidiary, First Financial Bank, to transfer funds to First Financial in the form of cash dividends, loans, other assets or advances. The approval of the Bank's primary federal regulator is required to pay dividends in excess of regulatory limitations. Dividends paid to First Financial from the Bank totaled $15.0 million for the first three months of 2018. As of March 31, 2018, the Bank had retained earnings of $570.4 million, of which $116.4 million was available for distribution to First Financial without prior regulatory approval. Additionally, First Financial had $54.3 million in cash at the parent company as of March 31, 2018, which approximates the Company’s annual regular shareholder dividend and operating expenses.
Share repurchases, if any, also impact First Financial's liquidity. For further information regarding share repurchases, see the Capital section that follows.
Capital expenditures, such as banking center expansions and technology investments were $5.0 million and $3.1 million for the first three months of 2018 and 2017, respectively. Management believes that sufficient liquidity exists to fund its future capital expenditure commitments.

Management is not aware of any other events or regulatory requirements that, if implemented, are likely to have a material effect on First Financial’s liquidity.
CAPITAL
Risk-Based Capital. The Board of Governors of the Federal Reserve System approved a rule implementing changes intended to strengthen the regulatory capital framework for all banking organizations (Basel III), subject to a phase-in period for certain provisions. Basel III established and defined quantitative measures to ensure capital adequacy which require First Financial to maintain minimum amounts and ratios of Common Equity tier 1 capital, total and tier 1 capital to risk-weighted assets and tier 1 capital to average assets (leverage ratio).
The rule includes a minimum ratio of common equity tier 1 capital to risk-weighted assets of 4.5% and a capital conservation buffer of 2.5% of risk-weighted assets that began on January 1, 2016 at 0.625% and will be phased in over a four year period, increasing by the same amount on each subsequent January 1, until fully phased-in on January 1, 2019. Further, the minimum ratio of Tier 1 capital to risk-weighted assets increased from 4.0% to 6.0% and all banks are now subject to a 4.0% minimum leverage ratio. The required total risk-based capital ratio is unchanged. Failure to maintain the required common equity Tier 1 capital conservation buffer will result in potential restrictions on a bank’s ability to pay dividends, repurchase stock and/or pay discretionary compensation to its employees. The capital requirements also provide strict eligibility criteria for regulatory capital instruments and change the method for calculating risk-weighted assets in an effort to better identify riskier assets, such as highly volatile commercial real estate and nonaccrual loans.
Management believes, as of March 31, 2018, that First Financial met all capital adequacy requirements to which it was subject. To be categorized as well-capitalized, First Financial must maintain minimum Total risk-based capital, Tier 1 risk-based capital and Tier 1 leverage ratios as set forth in the table that follows. The Company's most recent regulatory notifications categorized First Financial as "well-capitalized" under the regulatory framework for prompt corrective action. There have been no conditions or events since those notifications that management believes has changed the Company's categorization. Total regulatory capital exceeded the minimum requirement by $238.2 million on a consolidated basis at March 31, 2018.

First Financial generally seeks to balance the return of earnings to shareholders through shareholder dividends and share repurchases with capital retention, in order to maintain adequate levels of capital and support the Company's growth plans.
Shareholder Dividends. First Financial paid a dividend of $0.19 per common share on March 15, 2018 to shareholders of record as of March 1, 2017. Additionally, First Financial's board of directors authorized a dividend of $0.19 per common share, payable on June 15, 2018 to shareholders of record as of June 1, 2018.
Share Repurchases. In October 2012, First Financial's board of directors approved a share repurchase plan under which the Company has the ability to repurchase up to 5,000,000 shares. First Financial did not repurchase any shares under this plan during the first three months of 2018 and 2017. At March 31, 2018, 3,509,133 common shares remained available for repurchase under the 2012 share repurchase plan.
ATM Offering. In March 2017, First Financial initiated an "at-the-market" equity offering program to provide flexibility with respect to capital planning and to support future growth. First Financial was not active through the ATM program during the period.
Shareholders' Equity. Total shareholders’ equity at March 31, 2018 was $940.0 million compared to total shareholders’ equity at December 31, 2017 of $930.7 million.

RISK MANAGEMENT
First Financial manages risk through a structured ERM approach that routinely assesses the overall level of risk, identifies specific risks and evaluates specific actions to mitigate those risks. First Financial continues to enhance its risk management capabilities and has embedded risk awareness into the culture of the Company. First Financial has identified ten types of risk that it monitors in its ERM framework. These risks include credit, market, operational, compliance, strategic, reputation, information technology, cyber, legal and environmental/external.
For a full discussion of these risks, see the Enterprise Risk Management section in Management's Discussion and Analysis in First Financial’s 2017 Annual Report. The sections that follow provide additional discussion related to credit risk and market risk.
CREDIT RISK
Credit risk represents the risk of loss due to failure of a customer or counterparty to meet its financial obligations in accordance with contractual terms. First Financial manages credit risk through its underwriting process, periodically reviewing and approving its credit exposures using credit policies and guidelines approved by the board of directors.
ALLL. The ALLL is a reserve accumulated on the Consolidated Balance Sheets through the recognition of the provision for loan and lease losses. First Financial records a provision for loan and lease losses in the Consolidated Statements of Income to maintain the ALLL at a level considered sufficient to absorb probable incurred loan and lease losses inherent in the portfolio.
The ALLL was $54.4 million as of March 31, 2018 and $54.0 million as of December 31, 2017, and as a percentage of period-end loans, the ALLL was 0.89% as of March 31, 2018 compared to 0.90% as of December 31, 2017. The ALLL is consistent with the Company's overall credit outlook and stable classified asset balances.
The ALLL as a percentage of nonaccrual loans was 179.57% at March 31, 2018 and 224.32% at December 31, 2017. The ALLL as a percentage of nonperforming loans, including accruing TDRs, declined to 120.24% as of March 31, 2018 from 129.77% as of December 31, 2017 due to a $3.6 million, or 8.6%, increase in nonperforming loans. The increase in nonperforming loans during the first three months of 2018 was primarily driven by one commercial relationship downgraded to nonaccrual status during the period, which offset the Company's resolution efforts and positive credit risk rating migration.
First quarter 2018 net charge-offs were $1.9 million, or 0.13% of average loans and leases on an annualized basis, compared to net charge-offs of $2.0 million, or 0.14% of average loans and leases on an annualized basis for the comparable quarter in 2017.
Provision expense is a product of the Company's ALLL model, as well as net charge-off activity during the period. First quarter 2018 provision expense was $2.3 million compared to $0.4 million during the comparable quarter in 2017.
See Note 5 – Allowance for Loan and Lease Losses in the Notes to Consolidated Financial Statements, for further discussion of First Financial's ALLL.

MARKET RISK
Market risk is the risk of loss arising from adverse changes in the fair value of financial instruments due to changes in interest rates, foreign exchange rates and equity prices. The primary source of market risk for First Financial is interest rate risk. Interest rate risk is the risk to earnings and the value of the Company's equity arising from changes in market interest rates. Interest rate risk arises in the normal course of business to the extent that there is a divergence between the amount of interest-earning assets and the amount of interest-bearing liabilities that are prepaid, withdrawn, re-priced or mature in specified periods. First Financial seeks to achieve consistent growth in net interest income and equity while managing volatility from shifts in market interest rates.
First Financial monitors the Company's interest rate risk position using income simulation models and EVE sensitivity analyses that capture both short-term and long-term interest rate risk exposure. Income simulation involves forecasting NII under a variety of interest rate scenarios. EVE is calculated by discounting the cash flows for all balance sheet instruments under different interest-rate scenarios and First Financial uses EVE sensitivity analysis to understand the impact of changes in interest rates on long-term cash flows, income and capital. For both NII and EVE modeling, First Financial leverages instantaneous parallel shocks to evaluate interest rate risk exposure across rising and falling rate scenarios. Additional scenarios evaluated include implied market forward rate forecasts and various non-parallel yield curve twists.
First Financial’s interest rate risk models are based on the contractual and assumed cash flows and repricing characteristics for the Company’s assets, liabilities and off-balance sheet exposure. A number of assumptions are also incorporated into the interest rate risk models, including prepayment behaviors and repricing spreads for assets in addition to attrition and repricing rates for liabilities. Assumptions are primarily derived from behavior studies of the Company’s historical client base and are continually refined. Modeling the sensitivity of NII and EVE to changes in market interest rates is highly dependent on the assumptions incorporated into the modeling process.
Non-maturity deposit modeling is particularly dependent on the assumption for repricing sensitivity known as a beta. Beta is the amount by which First Financial’s interest bearing non-maturity deposit rates will increase when short-term interest rates rise. The Company utilized a weighted average deposit beta of 60% in its interest rate risk modeling as of March 31, 2018. First Financial also includes an assumption for the migration of non-maturity deposit balances into CDs for all upward rate scenarios beginning with the +100 bp scenario, thereby increasing deposit costs and reducing asset sensitivity.
Presented below is the estimated impact on First Financial’s NII and EVE position as of March 31, 2018, assuming immediate, parallel shifts in interest rates:

| % Change from base case for immediate parallel changes in rates
| -100 bps |  | +100 bps |  | +200 bps
NII-Year 1 | (5.89 | )% |  | 2.88 | % |  | 5.71 | %
NII-Year 2 | (7.21 | )% |  | 3.42 | % |  | 6.84 | %
EVE | (3.56 | )% |  | 0.85 | % |  | 1.79 | %

“Risk-neutral” refers to the absence of a strong bias toward either asset or liability sensitivity. “Asset sensitivity” is when a company's interest-earning assets reprice more quickly or in greater quantities than interest-bearing liabilities. Conversely, “liability sensitivity” is when a company's interest-bearing liabilities reprice more quickly or in greater quantities than interest-earning assets. In a rising interest rate environment, asset sensitivity results in higher net interest income while liability sensitivity results in lower net interest income. In a declining interest rate environment, asset sensitivity results in lower net interest income while liability sensitivity results in higher net interest income.
First Financial was within policy limits set for the disclosed interest rate scenarios as of March 31, 2018. The projected results for NII and EVE continued to reflect asset sensitivity during the first quarter of 2018 primarily related to high variable rate loan and noninterest bearing deposit balances, in addition to a lower mix of fixed rate investment securities. First Financial continues to manage its balance sheet with a bias toward asset sensitivity while simultaneously balancing the potential earnings impact of this strategy.
First Financial continually evaluates the sensitivity of its interest rate risk position to modeling assumptions. The following table reflects First Financial’s estimated NII sensitivity profile as of March 31, 2018 assuming a 25% increase and a 25% reduction to the beta assumption on managed rate deposits:

CRITICAL ACCOUNTING POLICIES
First Financial’s Consolidated Financial Statements are prepared based on the application of the Company's accounting policies. These policies require the reliance on estimates and assumptions. Changes in underlying factors, assumptions or estimates could have a material impact on First Financial’s future financial condition and results of operations. In management’s opinion, certain accounting policies have a more significant impact than others on First Financial’s financial reporting. For First Financial, these areas currently include accounting for the ALLL, goodwill, pension and income taxes. These accounting policies are discussed in detail in the Critical Accounting Policies section of Management’s Discussion and Analysis in First Financial’s 2017 Annual Report. There were no material changes to these accounting policies during the three months ended March 31, 2018.
ACCOUNTING AND REGULATORY MATTERS
Note 2 - Recently Adopted and Issued Accounting Standards in the Notes to Consolidated Financial Statements, discusses new accounting standards adopted by First Financial during 2018 and the expected impact of accounting standards recently issued but not yet required to be adopted. To the extent the adoption of new accounting standards materially affects financial condition, results of operations or liquidity, the impacts are discussed in the applicable section(s) of Management’s Discussion and Analysis and the Notes to the Consolidated Financial Statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The information contained in “Item 2-Management’s Discussion and Analysis of Financial Condition and Results of Operations—Market Risk” of this report is incorporated herein by reference in response to this item.
ITEM 4. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
Management is responsible for establishing and maintaining effective disclosure controls and procedures, as defined under
Rule 13a-15 of the Securities Exchange Act of 1934, that are designed to cause the material information required to be disclosed by First Financial in the reports it files or submits under the Securities Exchange Act of 1934 to be recorded, processed, summarized, and reported to the extent applicable within the time periods required by the Securities and Exchange Commission’s rules and forms. In designing and evaluating the disclosure controls and procedures, management recognized that a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected.
As of the end of the period covered by this report, First Financial performed an evaluation under the supervision and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures pursuant to Rule 13a-15 of the Securities Exchange Act of 1934. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
No changes were made to the Company's internal control over financial reporting (as defined in Rule 13a-15 under the Securities Exchange Act of 1934) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.
