NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the three months ended March 31, 2016 and 2015

Cheviot Financial Corp. (“Cheviot Financial” or the “Corporation”) is a savings and loan holding company, the principal asset of which consists of its ownership of Cheviot Savings Bank (the “Savings Bank”). The Savings Bank conducts a general banking business in southwestern Ohio, which consists of attracting deposits and applying those funds primarily to the origination of real estate loans. The Savings Bank’s profitability is significantly dependent on net interest income, which is the difference between interest income from interest-earning assets and the interest expense paid on interest-bearing liabilities. Net interest income is affected by the relative amount of interest-earning assets and interest-bearing liabilities and the interest received or paid on these balances.

On January 18, 2012, we completed our second step reorganization and sale of common stock. Prior to the completion of the second step conversion, Cheviot Financial was a federal corporation and mid-tier holding company. Following the reorganization Cheviot Financial is the Maryland incorporated holding company of the Savings Bank.

The accompanying unaudited consolidated financial statements were prepared in accordance with instructions for Form 10-Q and, therefore, do not include information or footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States of America. Accordingly, these consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto of Cheviot Financial included in the Annual Report on Form 10-K for the year ended December 31, 2015. However, in the opinion of management, all adjustments (consisting of only normal recurring accruals) which are necessary for a fair presentation of the consolidated financial statements have been included. The results of operations for the three month period ended March 31, 2016 are not necessarily indicative of the results which may be expected for the entire year.

On November 23, 2015, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with MainSource Financial Group, Inc., an Indiana corporation (“MainSource”), pursuant to which the Company will merge with and into MainSource, whereupon the separate corporate existence of the Company will cease and MainSource will survive (the “Merger”).  It is anticipated that immediately after the Merger, the Bank will merge with and into MainSource Bank, an Indiana chartered commercial bank and wholly-owned subsidiary of MainSource, with MainSource Bank as the surviving bank.

Subject to the approval of the Company’s shareholders of the Merger, regulatory approvals and other customary closing conditions, the parties anticipate completing the Merger in the second quarter of 2016. At the effective time of the Merger, the Company’s shareholders will have the right to elect to receive either 0.6916 shares of MainSource common stock or $15.00 in cash for each share of Company common stock owned, subject to proration provisions specified in the Merger Agreement that provide for a targeted aggregate split of total consideration of 50% common stock and 50% cash.

Cheviot Financial evaluates subsequent events through the date of filing with the Securities and Exchange Commission.

The accompanying consolidated financial statements as of and for the three months ended March 31, 2016 and 2015 include the accounts of the Corporation and its wholly-owned subsidiary, the Savings Bank. All significant intercompany items have been eliminated.

Liquidity describes our ability to meet the financial obligations that arise in the ordinary course of business. Liquidity is primarily needed to meet the borrowing and deposit withdrawal requirements of our customers and to fund current and planned expenditures. Our primary sources of funds are deposits, scheduled amortization and prepayments of loan principal and mortgage-backed securities, maturities and calls of securities and funds provided by our operations. In addition, we may borrow from the Federal Home Loan Bank of Cincinnati. At March 31, 2016 and December 31, 2015, we had $12.1 million and $12.6 million, respectively, in outstanding borrowings from the Federal Home Loan Bank of Cincinnati and had the capacity to increase such borrowings at those dates by approximately $135.6 million and $139.1 million, respectively.

Loan repayments and maturing securities are a relatively predictable source of funds. However, deposit flows, calls of securities and prepayments of loans and mortgage-backed securities are strongly influenced by interest rates, general and local economic conditions and competition in the marketplace. These factors reduce the predictability of these sources of funds.

Our primary investing activities are the origination of one- to four-family real estate loans, commercial real estate, construction and consumer loans, and the purchase of securities. For the three months ended March 31, 2016, loan originations totaled $16.7 million, compared to $24.4 million for the three months ended March 31, 2015.

Total deposits decreased $8.2 million during the three months ended March 31, 2016 and increased $3.7 million during the three months ended March 31, 2015. Deposit flows are affected by the level of interest rates, the interest rates and products offered by competitors and other factors.

The following table sets forth information regarding the Corporation’s obligations and commitments to make future payments under contracts as of March 31, 2016.

We are committed to maintaining a strong liquidity position and we monitor our liquidity position on a daily basis. We anticipate that we will have sufficient funds to meet our current funding commitments. Based on our deposit retention experience and current pricing strategy, we anticipate that a significant portion of maturing time deposits will be retained.

The following sets forth our regulatory capital position, compared to requirements to be considered “well-capitalized” as of March 31, 2016 under regulatory capital requirements enacted in 2015.

Basic earnings per share is computed based upon the weighted-average common shares outstanding during the period, less shares in the Employee Stock Ownership Plan (the “ESOP”) that are unallocated and not committed to be released plus shares in the ESOP that have been allocated. Weighted-average common shares deemed outstanding gives effect to 149,600 and 158,950 unallocated shares held by the ESOP for the three months ended March 31, 2016 and 2015, respectively.

The Corporation established Stock Incentive Plans that provides for grants of up to 884,018 stock options. During 2015, 189,070 stock options were granted in accordance with the 2005 and 2013 Equity Incentive Plans subject to a five year vesting period in which the options granted will vest ratably annually beginning one year from the date of grant. As of March 31, 2016, all option shares have been granted in accordance with the 2005 and 2013 Equity Incentive Plans. The shares in the 2005 plan and shares granted prior to the second step conversion have been adjusted to reflect the exchange ratio of 0.857 for the second step conversion that occurred in 2012.

The Corporation follows Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 718, “Compensation – Stock Compensation,” for its stock option plans, and accordingly, the Corporation recognizes the expense of these grants as required. Stock-based employee compensation costs pertaining to stock options is reflected as a net increase in equity, for both any new grants, as well as for all unvested options outstanding, in both cases using the fair values established by usage of the Black-Scholes option pricing model, expensed over the vesting period of the underlying option.

The compensation cost recorded for unvested equity-based awards is based on their grant-date fair value. For the three months ended March 31, 2016, the Corporation recorded $44,000 of compensation cost for equity-based awards that vested during the three months ended March 31, 2016. The Corporation has $621,000 of unrecognized compensation cost related to non-vested equity-based awards granted under its stock incentive plan as of March 31, 2016, which is expected to be recognized over a weighted-average vesting period of approximately 3.6 years.

A summary of the status of the Corporation’s stock option plans (or “stock opions”) as of March 31, 2016, and changes during the period then ended is presented below:

The following information applies to options outstanding at March 31, 2016:

The expected term of options is based on evaluations of historical and expected future employee exercise behavior. The risk free interest rate is based upon the U.S. Treasury rates at the date of grant with maturity dates approximately equal to the expected life at the grant date. Volatility is based upon the historical volatility of the Corporation’s stock.

The fair value of each option granted is estimated on the date of grant using the modified Black-Scholes options-pricing model with the following weighted-average assumptions used for the July 7, 2015 and May 4, 2015 grants: dividend yield of 2.70% and 2.33%; expected volatility of 15.09% and 15.56%; risk-free interest rates of 2.27% and 2.16%; and expected lives of 10 years. There were no grants during the three months ended March 31, 2016.

The effects of expensing stock options are reported in “cash provided by financing activities” in the Consolidated Statements of Cash Flows.

Management does not intend to sell any of the debt securities with an unrealized loss and does not believe that it is more likely than not that we will be required to sell a security in an unrealized loss position prior to a recovery in value. The decline in the fair value is primarily due to an increase in market interest rates. The fair values are expected to recover as securities approach maturity dates. The Corporation has evaluated these securities and has determined that the decline in their values is temporary.

The Corporation uses an asset and liability approach to accounting for income taxes. The asset and liability approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets are recognized if it is more likely than not that a future benefit will be realized. The Corporation accounts for income taxes in accordance with FASB ASC 740, Income Taxes, which prescribes the recognition and measurement criteria related to tax positions taken or expected to be taken in a tax return.

The Corporation’s principal temporary differences between financial income and taxable income result mainly from different methods of accounting for Federal Home Loan Bank stock dividends, the general loan loss allowance, deferred compensation, stock benefit plans, fair value adjustments arising from the First Franklin Corporation acquisition. The Corporation has approximately $400,000 of net operating losses to offset future taxable income. This amount is expected to be utilized during the current year.

The Corporation recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. At adoption date, January 1, 2007, the Corporation applied the standard to all tax positions for which the statute of limitations remained open and was not required to record any liability for unrecognized tax benefits as that date. There have been no material changes in unrecognized tax benefits since January 1, 2007.

The Corporation is subject to income taxes in the U.S. federal jurisdiction, as well as various state jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. With few exceptions, the Corporation is no longer subject to U.S. federal, state and local, or non U.S. income tax examinations by tax authorities for the years before 2012.

The Corporation will recognize, if applicable, interest accrued related to unrecognized tax liabilities in interest expense and penalties in operating expenses.

Federal income tax on earnings differs from that computed at the statutory corporate tax rate for the periods ended March 31, 2016 and 2015:

Fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practical to estimate the value, is based upon the characteristics of the instruments and relevant market information. Financial instruments include cash, evidence of ownership in an entity or contracts that convey or impose on an entity the contractual right or obligation to either receive or deliver cash for another financial instrument. These fair value estimates are based on relevant market information and information about the financial instruments. Fair value estimates are intended to represent the price for which an asset could be sold or liability could be settled. However, given there is no active market or observable market transactions identical to many of the Corporation’s financial instruments, estimates of many of these fair values are based upon observable inputs which are subjective in nature, involve uncertainties and matters of significant judgment, and therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimated values.

The following methods and assumptions were used by the Corporation in estimating its fair value disclosures for financial instruments at March 31, 2016:

Cash and cash equivalents : The carrying amounts presented in the consolidated statements of financial condition for cash and cash equivalents are deemed to approximate fair value.

Investment and mortgage-backed securities : For investment and mortgage-backed securities, fair value is deemed to equal the quoted market price.

Loans receivable : The loan portfolio was segregated into categories with similar characteristics, such as one-to four-family residential, multi-family residential and commercial real estate. These loan categories were further delineated into fixed-rate and adjustable-rate loans. The fair values for the resultant loan categories were computed via discounted cash flow analysis, using current interest rates offered for loans with similar terms to borrowers of similar credit quality. For loans on deposit accounts, fair values were deemed to equal the historic carrying values. The historical carrying amount of accrued interest on loans is deemed to approximate fair value.

Federal Home Loan Bank stock : The carrying amount presented in the consolidated statements of financial condition is deemed to approximate fair value.

For the three months ended March 31, 2016 and 2015

Deposits : The fair value of NOW accounts, passbook accounts, and money market demand deposits is deemed to approximate the amount payable on demand at March 31, 2016. Fair values for fixed-rate certificates of deposit have been estimated using a discounted cash flow calculation using the interest rates currently offered for deposits of similar remaining maturities.

Advances from the Federal Home Loan Bank : The fair value of these advances is estimated using the rates currently offered for similar advances of similar remaining maturities or, when available, quoted market prices.

Advances by Borrowers for Taxes and Insurance : The carrying amount of advances by borrowers for taxes and insurance is deemed to approximate fair value.

Commitments to extend credit : For fixed-rate loan commitments, the fair value estimate considers the difference between current levels of interest rates and committed rates. At March 31, 2016, the fair value of the derivative loan commitments was not material.

The estimated fair values of the Company’s financial instruments are as follows:

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A three-level hierarchy exists for fair value measurements based upon the inputs to the valuation of an asset or liability.

Fair value methods and assumptions are set forth below for each type of financial instrument.

Securities available for sale: Fair value on available for sale securities was based upon a market approach. Securities which are fixed income instruments that are not quoted on an exchange, but are traded in active markets, are valued using prices obtained from our custodian, which used third party data service providers and classified as level 2 assets. Management compares the fair values to another third party report for reasonableness. Available for sale securities includes U.S. agency securities, municipal bonds and mortgage-backed agency securities.

We adopted the following accounting guidance in 2016, which did not have a material effect, if any, on our consolidated financial position or results of operations.

In January 2016, FASB issued ASU No. 2016-01, Financial Instruments-Overall (Subtopic 825-10). The amendments in this update affect all entities that hold financial assets or owe financial liabilities. The update’s main provisions applicable to the Corporation are as follows: 1) Require equity investments with readily available fair values (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; 2) Simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; 3) Eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; 4) Require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; 5) Require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and 6) Clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. Public companies should apply the guidance in Update 2016-01 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is generally not permitted. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the annual reporting period of adoption. We do not expect the adoption of these provisions to have a significant impact on the Company’s consolidated financial statements.

The Corporation recorded goodwill and other intangibles associated with the purchase of First Franklin and Franklin Savings in March 2011 totaling $11.6 million. Goodwill is not amortized, but is periodically evaluated for impairment. The Corporation did not recognize any impairment during the quarter ended March 31, 2016. The carrying amount of the goodwill at March 31, 2016 was $10.3 million.

Identifiable intangibles are amortized to their estimated residual values over the expected useful lives. Such lives are also periodically reassessed to determine if any amortization period adjustments are required. During the quarter ended March 31, 2016, no such adjustments were recorded. The identifiable intangible asset consists of a core deposit intangible which is being amortized on an accelerated basis over the useful life of such asset. The gross carrying amount of the core deposit intangible at March 31, 2016 was $1.3 million with $1.1 million in accumulated amortization as of that date.

As of March 31, 2016, the current year and estimated future amortization expense for the core deposit intangible was:

Activity during 2016 for the accretable discount related to acquired credit impaired loans is as follows:

The recorded investment in loans was as follows as of March 31, 2016. Subsequent to acquisition, we regularly evaluate our estimates of cash flows expected to be collected on purchased impaired loans. If we have probable decreases in cash flows expected to be collected (other than due to decreases in interest rate indices and changes in prepayment assumptions), we charge the provision for credit losses, resulting in an increase to the allowance for loan losses. If we have probable and significant increases in cash flows expected to be collected, we first reverse any previously established allowance for loan losses and then increase interest income as a prospective yield adjustment over the remaining life of the loan, or pool of loans. Estimates of cash flows are impacted by changes in interest rate indices for variable rate loans and prepayment assumptions, both of which are treated as prospective yield adjustments included in interest income. Cheviot Financial’s allowance at March 31, 2016 does not include any credit quality discount related to loans acquired from First Franklin, other than $910,000 for certain one-to-four family residential and nonresidential and commercial real estate loans. Due to uncertainties in the evaluation of allowance for loan loss, it is at least reasonably possible that management’s estimate of the outcome will change within the next year.
