SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	1. Summary of Significant Accounting Policies The accounting policies of United Community Financial Corp. (United Community or the Company) and its subsidiaries, Home Savings Bank (Home Savings or the Bank), HSB Insurance, LLC, HSB Capital, LLC and HSB Insurance, Inc. conform to U.S. Generally Accepted Accounting Principles (GAAP) and prevailing practices within the banking and thrift industries. A summary of the more significant accounting policies follows. Nature of Operations The business of Home Savings is providing consumer and business banking service to its market area in Ohio, western Pennsylvania and West Virginia. At the end of 2017, Home Savings was doing business through 35 full service banking branches and 13 loan production centers and three wealth management offices. Loans and deposits are primarily generated from the areas where banking branches are located. Substantially all loans are secured by specific items of collateral including business assets, consumer assets, and commercial and residential real estate. Commercial loans are expected to be repaid from cash flow from operations of businesses. There are no significant concentrations of loans to any one industry or customer. However, the customers’ ability to repay their loans is dependent on the real estate and general economic conditions in the market area. Home Savings derives its income predominantly from interest on loans, securities, and to a lesser extent, non-interest income. Home Savings’ principal expenses are interest paid on deposits and Federal Home Loan Bank advances, loan loss provisions and normal operating costs. On January 29, 2016, United Community acquired James & Sons Insurance. James & Sons Insurance was merged into HSB Insurance, LLC, a wholly-owned subsidiary of United Community. HSB Insurance, LLC d/b/a James & Sons Insurance is an insurance agency that offers a wide variety of insurance products for business and residential customers, which include auto, homeowners, life-health, commercial, surety bonds and aviation. On February 28, 2017, James & Sons Insurance acquired Eich Brothers Insurance. Eich Brothers Insurance is an insurance agency that offers insurance products for business and residential customers, which include auto, commercial, homeowners and life-health. On July 1, 2017, James & Sons Insurance acquired Stevens Insurance Agency that offers insurance products for business and residential customers, which include auto, commercial, homeowners and life-health. HSB Capital, LLC was formed by United Community during 2016 for the purpose of providing mezzanine funding for customers. Mezzanine loans are offered to customers in United Community’s market area and are expected to be repaid from the cash flow from operations of the business. HSB Insurance, Inc., a wholly-owned subsidiary of the Company which was formed and began operations on June 1, 2017, is a Delaware-based captive insurance company which insures against certain risks unique to the operations of the Company and its subsidiaries and for which insurance may not be currently available or economically feasible in today’s insurance marketplace. HSB Insurance, Inc. pools resources with several other insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. HSB Insurance, Inc. is subject to regulations of the State of Delaware and undergoes periodic examinations by the Delaware Division of Insurance. Basis of Presentation The consolidated financial statements include the accounts of United Community and its subsidiaries. All material inter-company transactions have been eliminated. Certain prior period data has been reclassified to conform to current period presentation. These reclassifications had no effect on prior net income or shareholders’ equity. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. Cash Flows For purposes of the statement of cash flows, United Community considers all highly liquid investments with a term of three months or less to be cash equivalents. Net cash flows are reported for loan and deposit transactions, short-term borrowings and advance payments by borrowers for taxes and insurance. Securities Securities are classified as available for sale, held to maturity or trading upon their acquisition. Securities are classified as available for sale when they might be sold before maturity. Securities classified as available for sale are carried at estimated fair value with the unrealized holding gain or loss reported in other comprehensive income, net of tax. Securities classified as held to maturity are carried at amortized cost when management has the positive intent and ability to hold them to maturity. Equity securities with readily determinable fair values are classified as available for sale. Restricted securities such as FHLB stock are carried at cost. Interest income includes amortization of purchase premium or discount on debt securities. Premiums or discounts are amortized on the level-yield method without anticipating prepayments. Gains and losses on sales are recorded on the trade date and are determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (OTTI) at least quarterly, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of OTTI is recognized through earnings. Loans Held for Sale Loans held for sale primarily consist of residential mortgage loans originated for sale and other loans that have been identified for sale. If the fair value option has not been elected, the loans are carried at the lower of cost or fair value, determined in the aggregate. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Loans held for sale, for which the fair value option has been elected, are recorded at fair value as of each balance sheet date with the change in fair value recorded in earnings. The fair value of the Company’s construction perm loans held for sale is determined based on quoted prices for similar loans in active markets. The fair value of permanent construction loans held for sale is determined, based on the committed loan amount, using quoted prices for similar assets, adjusted for specific attributes of that loan and other unobservable market data, such as time it takes to complete the project. The fair value of conventional residential one-to four-family loans held for sale which the fair value option has been elected is determined based on quoted prices for similar loans in active markets. Since January 1, 2016, the Company elected the fair value option for all loans originated and held for sale. Mortgage loans held for sale are sold with either servicing rights retained or servicing released. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the outstanding principal balance, net of purchase premiums or discounts, deferred loan fees and costs and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Interest income includes amortization of net deferred loan fees and costs. Loan fees and costs associated with origination of loans are deferred and amortized to interest income over the contractual lives of the loans using the level yield method. Fees received for loan commitments that are expected to be drawn, based on Home Savings’ experience with similar commitments, are deferred and amortized over the lives of the loans using the level-yield method. Fees for other loan commitments are deferred and amortized over the loan commitment period on a straight-line basis. Unamortized deferred loan fees or costs related to loans paid off are included in income. Unamortized net fees or costs on loans sold are included in the basis of the loans in calculating gains and losses. The accrual of interest income and amortization of net deferred fees on mortgage and commercial loans is discontinued at the time the loan is 90 days delinquent unless the loan is both well secured and in the process of collection. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. All interest accrued but not received for a loan placed on nonaccrual is reversed against interest income. Once a loan is on nonaccrual, it will remain on nonaccrual until the loan becomes current and the borrower demonstrates the ability to pay the loan per the contractual terms for a minimum of six months. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. Loans are returned to accrual status when future payments are reasonably assured. Home Savings determines the past due status of loans based on the number of calendar months the loan is past due. Impaired loans consist of loans that are non-homogenous and in a nonaccrual status; loans considered troubled debt restructurings and loans that have been individually analyzed for impairment. Residential mortgage loans. Residential mortgage loans are revalued at the time they reach 180 days past due and any portion of the principal that exceeds the fair value is charged-off. Mortgage loans are considered to be homogenous until the loan is individually evaluated at 180 days past due and charged-down to the fair value of the underlying collateral, at which time the loan becomes non-homogenous and is considered impaired. Residential mortgage loans that have been modified and determined to be a troubled debt restructuring (TDR) are revalued based upon the present value of the modified cash flows of the loan to establish a specific reserve on that loan. Consumer loans. Consumer loans that are secured by residential real estate are revalued once they reach 180 days past due and charged-down to the fair value if necessary. Consumer loans that are not secured by residential real estate are revalued once they reach 120 days past due and are charged-down to the fair value if necessary. Consumer loans are considered to be homogenous until the loan is individually evaluated and charged-down to the fair value of the underlying collateral, at which time the loan becomes non-homogenous and is considered impaired. Consumer loans that have been modified and determined to be a TDR are revalued based upon the present value of the modified cash flows of the loan to establish a specific reserve on that loan. Commercial loans. A commercial real estate loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. At this time, the loan is charged-down to the fair value. Commercial and industrial loans are impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The repayment of commercial loans typically is dependent on the income stream and successful operation of a business. If there is no underlying collateral to value, the company will calculate the present value of expected future cash flows to determine the amount of impairment, if any. Concentration of Credit Risk Most of the Company’s business activity is with customers located within Home Savings’ market area. Therefore, the Company’s exposure to credit risk is significantly affected by changes in the economy in Ohio, Western Pennsylvania and Northern West Virginia. Allowance for Loan Losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required based on an analysis using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations, estimated collateral values, general economic conditions in the market area and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired or loans otherwise classified as substandard or doubtful. The general component covers non-classified loans and is based on historical loss experience adjusted for current factors. Other loans not reviewed specifically by management are evaluated as a homogenous group of loans (generally single-family residential mortgage loans and all consumer credits except marine loans) using a loss factor applied to the outstanding loan balance to determine the level of reserve required. This loss factor consists of two components, a quantitative and a qualitative component. The quantitative component is based on a historical analysis of all charged-off loans, net of recoveries, looking back 22 quarters as of December 31, 2017. In determining the qualitative component, consideration is given to such attributes as lending policies, economic conditions, nature and volume of the portfolio, management, loan quality trend, loan review, collateral value, concentrations, economic cycles and other external factors. The quantitative and qualitative components are combined to arrive at the loss factor, which is applied to the average outstanding balance of homogenous loans. At December 31, 2016, the Company evaluated 18 quarters of net charge-off history. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans are individually evaluated based on the borrower’s ability to repay the loan given the availability of collateral, other sources of cash flow and legal options available to Home Savings. Once a review is completed, a specific reserve is determined and allocated to the loan. These specific reserves on individual loans are reviewed periodically and adjusted as necessary based on subsequent collection, loan upgrades or downgrades, nonperforming trends or actual principal charge-offs. Loans for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the facts and circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. Troubled debt restructurings (TDRs) are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The Bank’s portfolio has the following segments: commercial, which includes commercial real estate secured loans, residential mortgage loans and consumer loans. Residential mortgage loans are made to customers in Home Savings’ market area. These loans are secured by the underlying real estate as collateral. Repayment of these loans is dependent on general economic conditions and unemployment levels in Home Savings’ market area. To reduce any risk on loans secured by one-to four-family residences, Home Savings underwrites all portfolio loans to Freddie Mac underwriting guidelines. Consumer loans primarily consist of home equity loans and lines of credit. Similar to residential mortgage loans, repayment of consumer loans depends on the general economic conditions and unemployment levels in Home Savings’ market area. The majority of Home Savings’ consumer loans consist of closed-end home equity loans and lines of credit in an amount that, when added to the prior indebtedness secured by the real estate, does not exceed 90% of the estimated value of the real estate. Other consumer loans, such as automobiles and recreational vehicles, have a higher degree of risk than home equity loans as the collateral depreciates at a faster rate. Multifamily and nonresidential real estate loans generally have a higher degree of risk than loans secured by one-to four-family residences. These riskier loans can be affected by economic conditions, operating expenses, debt service and successful operation of income-producing properties. Home Savings tries to reduce this risk by evaluating the credit history of the borrower, location of the real estate, the financial condition of the borrower, obtaining personal guarantees of the principals, the characteristics of the income stream generated by the property and the appraisal supporting the property. Commercial loans generally entail greater risk than real estate lending. The repayment of commercial loans typically is dependent on the income stream and successful operation of a business, which can be affected by economic conditions. The collateral for commercial loans, if any, often consists of rapidly depreciating assets. Construction loans involve a higher degree of underwriting and default risk than loans secured by mortgages on existing properties because construction loans are more difficult to appraise and to monitor. Loan funds are advanced based upon the status of the project under construction. Servicing Assets Servicing assets are recognized as separate assets when rights are acquired through the purchase or sale of financial assets. Servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Capitalized servicing rights are reported in other assets and are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying assets. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into tranches based on predominant risk characteristics, such as original maturity, interest rate and loan type. Impairment is recognized through a valuation allowance for an individual tranche. If Home Savings later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal, or a fixed amount per loan, and are recorded as income when earned. The amortization of mortgage servicing rights is shown separately in non-interest income. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Real Estate Owned and Other Repossessed Assets Real estate owned, including property acquired in settlement of foreclosed loans, is initially transferred at fair value less estimated cost to sell after foreclosure, establishing a new cost basis. Physical possession of residential real estate property collateralizing a residential mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines after acquisition, a valuation allowance is recorded through expense. Costs relating to the development and improvement of real estate owned are capitalized, whereas costs relating to holding and maintaining the properties are charged to expense. Other repossessed assets are carried at estimated fair value less estimated cost to sell after acquisition. Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Buildings and related components are depreciated and amortized using the straight-line method over the useful lives, generally ranging from 20 years to 40 years (or term of the lease, if shorter) of the related assets. Furniture and fixtures are depreciated using the straight-line method with useful lives ranging from three to five years. Federal Home Loan Bank (FHLB) stock The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Cash Surrender Value of Life Insurance Life insurance is carried on the lives of certain employees where Home Savings is the beneficiary. Life insurance is recorded at its cash surrender value, or the amount currently realizable. Increases in the Home Savings’ policy cash surrender value are tax exempt and death benefit proceeds received by Home Savings are tax-free. Income from these policies and changes in the cash surrender value are recorded in other income. The policies contain no split dollar or postretirement benefits for covered employees. Goodwill and other Intangible Assets Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interest in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. The Company has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consist of core deposit and customer list intangibles. Core deposit intangible assets arose from whole bank acquisitions. They were initially measured at fair value and are being amortized on an accelerated method over their estimated useful lives. Customer list intangible arose from the acquisition of James & Sons Insurance in January 2016 and Premier Bank and Trust in January 2017 and are amortized on an accelerated basis over its estimated useful life of 10 years. Derivatives At the inception of a derivative contract, the Company designates the derivative as one of three types based on the Company’s intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. Mortgage Banking Derivatives Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest rate on the loan is locked. The Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into in order to hedge the change in interest rates resulting from its commitments to fund the loans. Changes in the fair values of these derivatives are included in mortgage banking income on the consolidated statements of operations and comprehensive income. Long-term Assets Premises and equipment and other long–term assets are reviewed for impairment when events indicate their carrying amounts may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Stock Compensation Compensation cost is recognized for stock options and restricted stock awards issued to employees and nonemployee directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Corporation’s common shares at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax

BUSINESS COMBINATION	2. BUSINESS COMBINATION On January 31, 2017, United Community completed its acquisition of OLCB pursuant to the terms and conditions of the Agreement and Plan of Merger, dated as of September 8, 2016 by and among United Community, the Bank, OLCB and Premier Bank & Trust (the Merger Agreement). Pursuant to the terms of the Merger Agreement, OLCB was merged with and into United Community. Immediately following the merger, Home Savings was merged with and into Premier Bank & Trust, a wholly-owned subsidiary of OLCB, and changed its name to Home Savings Bank. As a result of the merger and in accordance with the terms of the Merger Agreement, each preferred shareholder of OLCB was deemed to have been converted into OLCB common shares. Each OLCB common share was converted into the right to receive either $18.00 in cash or 2.736 United Community common shares, subject to certain allocation procedures set forth in the Merger Agreement that ensured that 50% of OLCB’s common shares outstanding were converted into United Community common shares and 50% of OLCB’s common shares outstanding received the cash consideration. The Company issued cash in lieu of issuing fractional shares. After the allocation procedures were applied, the Company issued 3,033,604 United Community common shares and paid $20.4 million to OLCB shareholders as a result of the merger. Merger related costs aggregating $5.0 million were included in United Community’s Consolidated Statements of Operations for the year ended December 31, 2017. The fair value of the common shares issued as part of the consideration paid for OLCB was determined on the basis of the closing price of United Community’s commons shares on the date of consummation of the merger (the merger date). The following table summarizes the consideration paid for OLCB. (in thousands) Cash $ 20,379 United Community shares issued 25,816 Total fair value of consideration paid $ 46,195 At the merger date, United Community added the following to the Company’s consolidated statements of financial position: (in thousands) Cash $ 46,159 Loans 259,373 Available for sale securities 9,996 FHLB stock, at cost 1,256 Premises and equipment 2,940 Accrued interest 679 Other intangible assets 2,426 Other real estate owned 89 Other assets 7,240 Total assets acquired $ 330,158 Deposits assumed $ 266,279 Federal Home Loan Bank advances 23,500 Repurchase agreements and other borrowings 10,771 Accrued expenses and other liabilities 2,581 Total liabilities assumed $ 303,131 Goodwill created $ 19,168 The fair value of net assets acquired included fair value adjustments to certain receivables that were not considered impaired as of the merger date. The fair value adjustments were determined using discounted contractual cash flows. However, the Company believes that all contractual cash flows related to these financial instruments will be collected. As such, these receivables were not considered impaired at the merger date and were not subject to the guidance relating to purchased credit impaired loans, which have shown evidence of credit deterioration since origination. The Company has purchased loans, for which there was, at the merger date, evidence of deterioration of credit quality since origination and it was probable, at the merger date, that all contractually required payments would not be collected with a fair value and gross contractual amounts receivable of $1.8 million and $3.3 million, respectively, on the merger date. Upon adoption of ASU 2016-16, Business Combinations (Topic 805) The following table presents proforma information as if the OLCB merger had occurred at the beginning of 2016. The proforma information includes adjustments for interest income on loans and securities acquired, amortization of intangibles arising from the transaction, depreciation expense on property acquired, interest expense on deposits acquired, and the related income tax effects. The proforma financial information is not necessarily indicative of the results of operations that would have occurred had the transaction been effected on the assumed dates. Net income includes the recognition of $5.0 million in merger related expenses incurred by United Community and $368,000 in merger related expenses for OLCB during the twelve months ended December 31, 2017. The impact of the acquired insurance agencies is considered immaterial and not included in the table below. For the Year Ended December 31, 2017 2016 (In thousands, except per share data) Net interest income $ 82,286 $ 75,443 Net income 21,430 16,770 Basic earnings per share $ 0.43 $ 0.38 Diluted earnings per share $ 0.43 $ 0.37 Goodwill is recorded arising from the merger, which consisted largely of synergies and the cost savings resulting from combining the operations of the companies. No goodwill is expected to be deductible for income tax purposes. At the time of the closing, Home Savings’ charter changed to a state chartered commercial bank and United Community became a financial holding company. The merger benefits the Company and its shareholders by enabling the Company to further expand into the markets currently served by OLCB and PB&T and strengthening the competitive position of the combined organization. Furthermore, the Company believes its increased asset size after the merger will create additional economies of scale and provide opportunities for asset and earnings growth in an extremely competitive banking environment. OLCB results of operations were included in the Company’s results beginning January 31, 2017. On February 28, 2017, HSB Insurance, LLC completed the purchase of an insurance agency engaged in the business of selling insurance including auto, commercial, homeowners and life-health insurance. Under the purchase agreement, the Company paid $535,000, of which $107,000 was paid in cash at closing and the remaining $428,000 will be paid in four equal installments in connection with this acquisition. Total assets purchased were $722,000, which includes the customer list intangible and goodwill. On July 1, 2017, HSB Insurance, LLC completed the purchase of an insurance agency engaged in the business of selling insurance including auto, commercial, homeowners and life-health insurance. Under the purchase agreement, the Company paid $60,000, of which $23,000 was paid in cash at closing and the remaining $37,000 will be paid in two equal installments in connection with this acquisition. Total assets purchased were $81,000, which includes the customer list intangible and goodwill.

Unrealized losses on these securities have not been recognized into income as of December 31, 2017 because the issuer’s securities are of high credit quality (rated AA or higher), management does not intend to sell, and it is likely that management will not be required to sell, the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in interest rates and other market conditions.

During the third quarter of 2015, Home Savings transferred mortgage-backed GSE securities with a total amortized cost of $105.3 million with a corresponding fair value of $103.8 million from available for sale to held to maturity. The net unrealized loss, net of taxes, on these securities at the date of transfer was $999,000. The fair value at the date of transfer becomes the securities’ new cost basis. The unrealized holding loss at the time of transfer continues to be reported in accumulated other comprehensive income, net of tax and is amortized over the remaining lives of the securities as an adjustment of the yield. The amortization of the unamortized holding loss reported in accumulated other comprehensive income will directly offset the effect on interest income from the accretion of the reduced amortized cost for the transferred securities. The remaining unaccreted unrealized holding loss totaled $1,035,000 at December 31, 2017 and $1,230,000 at December 31, 2016. Because of this transfer, the total losses less than 12 months and greater than 12 months reported in the table below will not agree to the unrealized losses reported in the inventory of held to maturity securities. The inventory table reports unrealized gains and losses based upon the transferred securities adjusted cost basis and current fair value. The reporting of losses less than 12 months and greater than 12 months represents that actual period of time that these securities have been in an unrealized loss position and the securities amortized cost basis as if the transfer did not occur.

Commitments generally have fixed expiration dates or other termination clauses, may require payment of a fee and may expire unused. Commitments to extend credit at fixed rates expose Home Savings to some degree of interest rate risk. Home Savings evaluates each customer’s creditworthiness on a case-by-case basis. The type or amount of collateral obtained varies and is based on management’s credit evaluation of the potential borrower. Home Savings normally has a number of outstanding commitments to extend credit.

The fixed rate loan commitments have interest rates ranging from 2.75% to 18.00%; and maturities ranging from three months to thirty years. Commitments to fund certain mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. It is the Company’s practice to enter into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from its commitments to fund the loans. These mortgage banking derivatives are not designated as hedge relationships. At December 31, 2017 and 2016, there were $239,000 and $1.0 million of outstanding standby letters of credit, respectively. These are issued to guarantee the performance of a customer to a third party. Standby letters of credit are generally contingent upon the failure of the customer to perform according to the terms of an underlying contract with the third party. At December 31, 2017 and 2016, there were $54.4 million and $50.5 million in outstanding commitments to fund the OverdraftPrivilege™ Program at Home Savings. With OverdraftPrivilege™, Home Savings pays non-sufficient funds checks and fees on checking accounts up to a preapproved limit. The following tables present the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and based on impairment method as of December 31, 2017 and December 31, 2016 and activity for the years ended December 31, 2017, 2016 and 2015.

The recorded investment includes the unpaid principal balance less any chargeoffs or partial chargeoffs applied to specific loans. The unpaid principal balance and the recorded investment both exclude accrued interest receivable and deferred loan costs, both of which are immaterial. The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required based on an analysis using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations, estimated collateral values, general economic conditions in the market area and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. Other loans not reviewed specifically by management are evaluated as a homogenous group of loans (generally single-family residential mortgage loans and all consumer credits except marine loans) using a loss factor applied to the outstanding loan balance to determine the level of reserve required. This loss factor consists of two components, a quantitative and a qualitative component. The quantitative component is based on a historical analysis of all charged-off loans, net of recoveries, looking back 22 quarters as of December 31, 2017. In determining the qualitative component, consideration is given to such attributes as lending policies, economic conditions, nature and volume of the portfolio, management, loan quality trend, loan review, collateral value, concentrations, economic cycles and other external factors. The quantitative and qualitative components are combined to arrive at the loss factor, which is applied to the average outstanding balance of homogenous loans. At December 31, 2016, the Company evaluated 18 quarters of net charge-off history.

there are two related credits with a total principal balance outstanding of $7.0 million as of December 31, 2015. The source of repayment for the loan resides in funds held in escrow by a court that has administered foreclosure and receivership proceedings surrounding the loan. The loan has been subject to protracted litigation and a reserve of $546,000 was placed on one of the loans in 2015. In 2016, this relationship was reclassified as a nonperforming asset within other assets and is no longer included in loan balances. Home Savings believes that the asset that remains no longer represents a loan. Other than the funds held in the Receiver Estate, there are no additional assets to which Home Savings can assert a claim against as the corporate borrowers have been liquidated and dissolved, and the individual guarantors have no remaining assets. In December 2017, an appellate court ruled that a portion of the proceeds should be awarded to another claimant. Subsequently the asset was written down $2.3 million, through other expenses, to $4.1 million to reflect the court ruling. It is the Company’s intent to continue to pursue a full recovery. As a result, it is most appropriate to categorize these proceeds as a nonperforming “other asset” identified as a current receivable from the court. The Company reclassifies a collateralized mortgage loan and consumer loans secured by real estate to real estate owned and other repossessed assets once it has either obtained legal title to the real estate collateral or the borrower voluntarily conveys all interest in the real property to the Bank to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. The table below presents loans that are in the process of foreclosure at December 31, 2017 and December 31, 2016, but legal title, deed in lieu of foreclosure or similar legal agreement to the property has not yet been obtained: December 31, 2017 December 31, 2016 Unpaid Principal Balance Recorded Investment Unpaid Principal Balance Recorded Investment Mortgage loans in the process of

During the periods ended December 31, 2017, 2016 and 2015, the terms of certain loans were modified as TDRs. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan. Modifications involving a reduction of the stated interest rate of a loan were for periods ranging from six months to 2 years. Modifications involving an extension of the maturity date were for periods ranging from six months to ten years. As of December 31, 2017 and December 31, 2016, the Company has a recorded investment in troubled debt restructurings of $19.8 million and $26.6 million, respectively. The Company has allocated $1.6 million of specific reserves to customers whose loan terms were modified in TDRs as of December 31, 2017. The Company had allocated $3.0 million of specific reserves to customers whose loan terms were modified in troubled debt restructurings as of December 31, 2016. The Company committed to lend additional amounts totaling up to $37,000 and $31,000 at December 31, 2017 and December 31, 2016, respectively. TDR loans that were on nonaccrual status aggregated $2.4 million and $6.6 million at December 31, 2017 and December 31, 2016, respectively. Such loans are considered nonperforming loans. TDR loans that were accruing according to their terms aggregated $17.9 million and $20.0 million at December 31, 2017 and December 31, 2016, respectively. There were no loans modified as TDRs for which there was a payment default within twelve months following the modification during the period ended December 31, 2017. A TDR is considered to be in payment default once it is 30 days contractually past due under the modified terms. The terms of certain other loans were modified during the period ended December 31, 2017, but they did not meet the definition of a TDR. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant.

The terms of certain other loans were modified during the period ended December 31, 2015, but they did not meet the definition of a TDR. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant. In order to determine whether a borrower is experiencing financial difficulty an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed in accordance with the Company’s internal underwriting policy. Credit Quality Indicators: The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, credit documentation, public information and current economic trends among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes homogeneous loans past due 90 cumulative days, and all non-homogeneous loans including commercial loans and commercial real estate loans. Smaller balance homogeneous loans are primarily monitored by payment status. Asset quality ratings are divided into two groups: Pass (unclassified) and Classified. Within the unclassified group, loans that display potential weakness are risk rated as special mention. In addition, there are three classified risk ratings: substandard, doubtful and loss. These specific credit risk categories are defined as follows: Special Mention. Loans classified as special mention have potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Loans may be housed in this category for no longer than 12 months during which time information is obtained to determine if the credit should be downgraded to the substandard category. Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Loss. Loans classified as loss are considered uncollectible and of such little value, that continuance as assets is not warranted. Although there may be a chance of recovery on these assets, it is not practical or desirable to defer writing off the asset. The Company monitors loans on a monthly basis to determine if they should be included in one of the categories listed above. All impaired non-homogeneous credits classified as Substandard, Doubtful or Loss are analyzed on an individual basis for a specific reserve requirement. This analysis is performed on each individual credit at least annually or more frequently if warranted. As of December 31, 2017 and December 31, 2016, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows: December 31, 2017 (Dollars in thousands) Unclassified Classified Unclassified Special Mention Substandard Doubtful Loss Total Classified Total Loans Commercial Loans Multifamily $ 118,716 $ 1,334 $ 430 $ — $ — $ 430 $ 120,480 Nonresidential 367,553 6,394 7,664 — — 7,664 381,611 Land 15,153 — 9 — — 9 15,162 Construction 116,460 403 — — — — 116,863 Secured 149,912 6,092 21,990 — — 21,990 177,994 Unsecured 10,412 — 94 — — 94 10,506 Total commercial loans 778,206 14,223 30,187 — — 30,187 822,616 Residential mortgage loans One-to four-family 861,971 1,585 7,383 — — 7,383 870,939 Construction 49,092 — — — — — 49,092 Total residential mortgage loans 911,063 1,585 7,383 — — 7,383 920,031 Consumer Loans Home equity 193,733 — 2,119 — — 2,119 195,852 Auto 64,209 — 155 — — 155 64,364 Marine 1,345 — 181 — — 181 1,526 Recreational vehicle 5,488 — 208 — — 208 5,696 Other 6,051 — 5 — — 5 6,056 Total consumer loans 270,826 — 2,668 — — 2,668 273,494 Total loans $ 1,960,095 $ 15,808 $ 40,238 $ — $ — $ 40,238 $ 2,016,141 December 31, 2016 (Dollars in thousands) Unclassified Classified Unclassified Special Mention Substandard Doubtful Loss Total Classified Total Loans Commercial Loans Multifamily $ 89,468 $ 3,564 $ 565 $ — $ — $ 565 $ 93,597 Nonresidential 217,204 6,037 8,160 — — 8,160 231,401 Land 8,339 — 34 — — 34 8,373 Construction 68,158 — — — — — 68,158 Secured 89,756 3,420 2,167 — — 2,167 95,343 Unsecured 7,291 — 95 — — 95 7,386 Total commercial loans 480,216 13,021 11,021 — — 11,021 504,258 Residential mortgage loans One-to four-family 754,996 104 7,826 — — 7,826 762,926 Construction 35,695 — — — — — 35,695 Total residential mortgage loans 790,691 104 7,826 — — 7,826 798,621 Consumer Loans Home equity 163,101 — 1,953 — — 1,953 165,054 Auto 39,577 1 31 — — 31 39,609 Marine 1,530 — 266 — — 266 1,796 Recreational vehicle 7,424 — 178 — — 178 7,602 Other 2,535 — 2 — — 2 2,537 Total consumer loans 214,167 1 2,430 — — 2,430 216,598 Total loans $ 1,485,074 $ 13,126 $ 21,277 $ — $ — $ 21,277 $ 1,519,477 Directors and officers of the Company are loan customers in the ordinary course of business.

MORTGAGE BANKING ACTIVITIES	6. MORTGAGE BANKING ACTIVITIES Mortgage loans serviced for others, which are not reported in United Community’s assets, totaled $1.3 billion at December 31, 2017 and $1.2 billion as of December 31, 2016. Mortgage banking income is comprised of gains recognized on the sale of loans and changes in fair value of mortgage banking derivatives and changes in fair value of loans held for sale carried at fair value. Mortgage loans serviced for others are not reported as assets. The principal balance of these loans at year-end are as follows: 2017 2016 (Dollars in thousands) Mortgage loan portfolios serviced for: FHLMC $ 1,003,441 $ 956,278 FNMA 242,444 208,114 Private investor 23,404 - Customer escrow balances in connection with loans serviced for FHLMC and FNMA totaled $15.3 million and $14.3 million at year-end 2017 and 2016. Activity for capitalized mortgage servicing rights, included in other assets, was as follows: For the Year Ended December 31, 2017 2016 2015 (Dollars in thousands) Balance, beginning of period $ 6,070 $ 5,686 $ 5,535 Originations 2,555 2,478 1,951 Amortized to expense (1,944 ) (2,094 ) (1,800 ) Balance, end of period 6,681 6,070 5,686 Less valuation allowance (9 ) — (39 ) Net balance $ 6,672 $ 6,070 $ 5,647 Fair value of mortgage servicing rights was $10.9 million, $10.2 million and $9.1 million at December 31, 2017, 2016, and 2015, respectively. Activity in the valuation allowance for mortgage servicing rights was as follows: For the Year Ended December 31, 2017 2016 2015 (Dollars in thousands) Balance, beginning of period $ — $ (39 ) $ (58 ) Impairment charges (15 ) (727 ) (299 ) Recoveries 6 766 318 Balance, end of period $ (9 ) $ — $ (39 ) Key economic assumptions used in measuring the value of mortgage servicing rights at December 31, 2017 and 2016 were as follows: 2017 2016 Weighted average prepayment rate 181 PSA 165 PSA Weighted average life (in years) 6.35 6.64 Weighted average discount rate 9 % 9 % At year-end 2017, the Company had approximately $40.2 million of interest rate lock commitments and $155.0 million of forward commitments for the future delivery of residential mortgage loans, including construction perm loans that are held in available for sale. At year-end 2016, the Company had approximately $30.2 million of interest rate lock commitments and $124.0 million of forward commitments for the future delivery of residential mortgage loans, including construction perm loans that are held in available for sale. The fair value of these mortgage banking derivatives was not material at year-end 2017 or 2016. Home Savings may receive requests for reimbursements from Freddie Mac and Fannie Mae, both of whom in the normal course purchase loans originated by Home Savings, for the purpose of making them whole on certain loans sold in the secondary market. These sold loans may have certain identified weaknesses such that, in the opinion of management, a settlement to the investor might be required. For the twelve months ended December 31, 2017, Home Savings recognized no expenses associated with such repurchases. Home Savings had no liability reserve for future make-whole settlements at December 31, 2017 and 2016 because management believed no reserve was necessary given the recent historical losses incurred to date, there were no loans in the pipeline to be repurchased and the probability that future losses will not occur. For the twelve months ended December 31, 2016, Home Savings recognized no expenses associated with such repurchases. For the twelve months ended December 31, 2015, Home Savings recognized a recovery of expenses of $554,000 associated with such repurchases.

Impairment exists when a reporting unit’s carrying value of goodwill exceeds its fair value. If the carrying amount of a reporting unit is zero or less than zero, a qualitive analysis of whether it is more likely than not that the reporting unit goodwill is impaired will be performed. The qualitative assessment indicated that it was more likely than not that the fair value of the reporting unit exceeded its carrying value, resulting in no impairment. The Company did not have any reporting unites with a carrying amount of zero or less than zero at December 31, 2017 or 2016.

At December 31, 2016, Home Savings had remaining available credit, subject to collateral requirements, with the FHLB of approximately $172.1 million. All advances must be secured by eligible collateral as specified by the FHLB. Accordingly, Home Savings had a blanket pledge of its one-to four-family mortgages as collateral for the advances outstanding at December 31, 2017 and 2016. The required minimum ratio of collateral to advances is 120% for one-to four-family loans. Additional changes in value can be applied to one-to four-family mortgage collateral based upon characteristics such as loan-to-value ratios and FICO scores. On November 18, 2014, Home Savings modified a $50.0 million fixed-rate term advance with the FHLB. The modification reduced the weighted average interest rate paid on the debt from 4.20% fixed-rate to a floating rate, and extended the weighted average maturity from 2.0 years to 5.0 years. A $3.9 million prepayment penalty was incurred by Home Savings as part of the modification which will be amortized using a level yield method over the five-year remaining term of the modified borrowing as a yield adjustment. The floating rate was 1.70% at December 31, 2017 and 1.16% at December 31, 2016. The effective rate on the modified borrowing was 3.26% at December 31, 2017 and 2.73% at December 31, 2016, including the impact of the prepayment penalty amortization. FHLB term advances are subject to prepayment penalties.

Management considers the nature and amount of projected future taxable income, the scheduled reversal of deferred tax assets and liabilities, and available tax planning strategies in making this assessment. The amount of deferred taxes recognized could be impacted by changes to any of these variables. United Community’s net operating loss of $4.4 million will be carried forward to use against future taxable income. The net operating loss carryforwards begin to expire in the year ending December 31, 2027. In addition, United Community is carrying forward $2.2 million of alternative minimum tax credits. The alternative minimum tax credits are carried forward indefinitely. Certain of these tax benefits are subject to annual limitation under Internal Revenue Code section 382; however, United Community and Home Savings expect to utilize the full amount of the benefit. Retained earnings at December 31, 2017 included approximately $21.1 million for which no provision for federal income taxes has been made. This amount represents the tax bad debt reserve at December 31, 1987, which is the end of United Community’s base year for purposes of calculating the bad debt deduction for tax purposes. If this portion of retained earnings is used in the future for any purpose other than to absorb bad debts, the amount used will be added to future taxable income. The unrecorded deferred tax liability on the above amount at December 31, 2017 was approximately $4.4 million. At December 31, 2017, Home Savings had approximately $17.6 million deficit in tax earnings and profits. Any distribution from Home Savings to United Community, other than current period earnings, in excess of tax earnings and profits, including any distributions made by Home Savings in direct redemption of stock from United Community, could result in recapture of proportionate amounts of these bad debt reserves and, as a result, recording of the related tax liability. As of December 31, 2017 and December 31, 2016, United Community had no unrecognized tax benefits or accrued interest and penalties recorded. United Community does not expect the total amount of unrecognized tax benefits to significantly increase within the next twelve months. United Community will record interest and penalties as a component of income tax expense. United Community and Home Savings are subject to U.S. federal income tax. United Community and Home Savings are subject to tax in Ohio based upon its net worth. United Community and Home Savings also file state income tax returns in Pennsylvania, Indiana, West Virginia and Florida. United Community is no longer subject to examination by taxing authorities for years prior to 2014. On December 22, 2017, H.R. 1, commonly known as the Tax Cuts and Jobs Act (the “Act”), was signed into law. The Act includes several provisions that will affect the Company’s federal income tax expense, including reducing the federal income tax rate to 21% effective January 1, 2018. As a result of the rate reduction, the Company is required to re-measure, through income tax expense in the period of enactment, the deferred tax assets and liabilities using the enacted rate at which these items are expected to be recovered or settled. The re-measurement of the Company’s net deferred tax asset resulted in additional 2017 income tax expense of $1.5 million.

Equity [Abstract]
SHAREHOLDERS? EQUITY	15. SHAREHOLDERS’ EQUITY Dividends United Community’s source of funds for dividends to its shareholders is earnings on its investments and dividends from Home Savings. During the year ended December 31, 2017, United Community paid total cash dividends of $0.14 per common share. While Home Savings’ primary regulator is the FDIC, the FRB has regulations that impose certain restrictions on payments of dividends to United Community as of December 31, 2017. Home Savings must file an application with, and obtain approval from, the FRB if (i) the proposed distribution would cause total distributions for the calendar year to exceed net income for that year-to-date plus retained net income (as defined) for the preceding two years; (ii) Home Savings would not be at least adequately capitalized following the capital distribution; or (iii) the proposed distribution would violate a prohibition contained in any applicable statute, regulation or agreement between Home Savings and the FRB or the FDIC, or any condition imposed on Home Savings in an FRB-approved application or notice. If Home Savings is not required to file an application, it must file a notice of the proposed capital distribution with the FRB. As of December 31, 2017, Home Savings had no retained earnings that could be distributed based on cumulative dividends and net income over the aforementioned period. Home Savings paid a $15.0 million dividend to United Community from current period earnings during 2017. Accumulated Other Comprehensive Income (Loss) Accumulated other comprehensive income (loss) included in the consolidated statements of shareholders’ equity consists of unrealized gains and losses on available for sale securities, unrealized losses on securities transferred from available for sale to held to maturity, accretion of unrealized losses on securities transferred from available for sale to held to maturity, disproportional tax effects and changes in unrealized gains and losses on the postretirement plan. The change includes reclassification of net gains or (losses) on sales of securities of $566,000, $604,000 and $142,000 for the years ended December 31, 2017, 2016 and 2015. The following is a summary of accumulated other comprehensive income (loss) to net income balances: Unrealized Gains (Losses) on Securities Available for Sale Disproportionate Tax Effect from Securities Available for Sale Unrealized Gains (Losses) on Held to Maturity Total 2017 (Dollars in thousands) Balances at beginning of period, net of tax $ (3,130 ) $ (17,110 ) $ (800 ) $ (21,040 ) Other comprehensive loss before reclassifications 2,946 — — 2,946 Accretion of unrealized losses transferred from available for sale to held to maturity recognized in other comprehensive income — — 129 129 Reclassification adjustment for gains realized in income (368 ) — — (368 ) Net current period other comprehensive income 2,578 — 129 2,707 Reclassification from adoption of ASU 2018-02 (352 ) — — (352 ) Balances at end of period, net of tax $ (904 ) $ (17,110 ) $ (671 ) $ (18,685 ) Unrealized Gains (Losses) on Securities Available for Sale Disproportionate Tax Effect from Securities Available for Sale Unrealized Gains (Losses) on Held to Maturity Unrealized Gains (Losses) from Postretirement Plan Disproportionate Tax Effect from Postretirement Plan Total 2016 (Dollars in thousands) Balances at beginning of period, net of tax $ (2,492 ) $ (17,110 ) $ (960 ) $ 831 $ 511 $ (19,220 ) Transfer of losses from available for sale to held to maturity (245 ) — — — — (245 ) Other comprehensive income before reclassifications — — — (831 ) (511 ) (1,342 ) Accretion of unrealized losses transferred from available for sale to held to maturity recognized in other comprehensive income — — 160 — — 160 Reclassification adjustment for gains realized in income (393 ) — — — (393 ) Net current period other comprehensive income (638 ) — 160 (831 ) (511 ) (1,820 ) Balances at end of period, net of tax $ (3,130 ) $ (17,110 ) $ (800 ) $ — $ — $ (21,040 ) Unrealized Gains (Losses) on Securities Available for Sale Disproportionate Tax Effect from Securities Available for Sale Unrealized Gains (Losses) on Held to Maturity Unrealized Gains (Losses) from Postretirement Plan Disproportionate Tax Effect from Postretirement Plan Total 2015 (Dollars in thousands) Balances at beginning of period, net of tax $ (4,315 ) $ (17,110 ) $ — $ 916 $ 511 $ (19,998 ) Transfer of losses from available for sale to held to maturity 999 — (999 ) — — — Other comprehensive income before reclassifications 916 — — 120 — 1,036 Accretion of unrealized losses transferred from available for sale to held to maturity recognized in other comprehensive income — — 39 — — 39 Reclassification adjustment for gains realized in income (92 ) — — (205 ) — (297 ) Net current period other comprehensive income 1,823 — (960 ) (85 ) — 778 Balances at end of period, net of tax $ (2,492 ) $ (17,110 ) $ (960 ) $ 831 $ 511 $ (19,220 ) As of June 30, 2014, management concluded it was more likely than not that the Company’s net deferred tax asset (DTA) would be realized and accordingly determined a full deferred tax valuation allowance was no longer required. Upon reversal of the former full deferred tax valuation allowance as of June 30, 2014, certain disproportionate tax effects are retained in accumulated other comprehensive income (loss) totaling approximately a ($16.6) million loss. Almost the entire disproportionate tax effect is attributable to valuation allowance expense recorded through other comprehensive income (loss) on the tax benefit of losses sustained on the available for sale securities portfolio while the Company was in a full deferred tax valuation allowance. This valuation allowance was appropriately reversed through continuing operations at June 30, 2014, leaving the original expense in accumulated other comprehensive income (loss), where it will remain in accordance with the Company’s election of the “portfolio approach”, until such time as the Company would cease to have an available for sale security portfolio. During 2016, with the termination and settlement of the postretirement plans, the disproportionate tax effect associated with these plans was reversed and recorded as a tax benefit. The following is significant amounts reclassified out of each component of accumulated comprehensive income (loss) to net income for the year ended December 31, 2017: Amount Reclassified From Accumulated Details About Accumulated Other Other Comprehensive Affected Line Item on the Statement Where Comprehensive Income Components Income to Net Income Net Income is Presented (Dollars in thousands) Realized net gains on the sale of available for sale securities $ 566 Net gains on securities available for sale (198 ) Tax (expense) benefit Total reclassification during the period $ 368 Increase to net income The following is significant amounts reclassified out of each component of accumulated comprehensive income (loss) to net income for the year ended December 31, 2016: Amount Reclassified From Accumulated Details About Accumulated Other Other Comprehensive Affected Line Item on the Statement Where Comprehensive Income Components Income to Net Income Net Income is Presented (Dollars in thousands) Realized net gains on the sale of available for sale securities $ 604 Net gains on securities available for sale (211 ) Tax (expense) benefit 393 Net of tax Amortization of postretirement benefits prior service costs 1,278 Reduction of salaries & employee benefits expense (447 ) Tax (expense) benefit 511 Disproportionate tax benefit effect from plan settlement 1,342 Net of tax Total reclassification during the period $ 1,735 Increase to net income The following is significant amounts reclassified out of each component of accumulated comprehensive income (loss) for the year ended December 31, 2015: Amount Reclassified From Accumulated Details About Accumulated Other Other Comprehensive Affected Line Item on the Statement Where Comprehensive Income Components Income to Net Income Net Income is Presented (Dollars in thousands) Realized net gains on the sale of available for sale securities $ 142 Net gains on securities available for sale (50 ) Tax (expense) benefit 92 Net of tax Amortization of postretirement benefits prior service costs 315 Reduction of salaries & employee benefits expense (110 ) Tax (expense) benefit 205 Net of tax Total reclassification during the period $ 297 Increase to net income Liquidation Account At the time of the Conversion, Home Savings established a liquidation account, totaling $141.4 million, which was equal to its regulatory capital as of the latest practicable date prior to the Conversion. In the event of a complete liquidation, each eligible depositor will be entitled to receive a distribution from the liquidation account in an amount proportionate to the current adjusted qualifying balances for the accounts then held.

REGULATORY CAPITAL MATTERS	16. REGULATORY CAPITAL MATTERS Home Savings and United Community are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on Home Savings and United Community. The regulations require Home Savings to meet specific capital adequacy guidelines in keeping with the regulatory framework for prompt corrective action that involve quantitative measures of Home Savings’ assets, liabilities, and certain off balance sheet items as calculated under regulatory accounting practices. Home Savings’ capital classification is also subject to qualitative judgments by the regulators about components of capital, risk weightings, and other factors. The Basel III Capital Rules establish a common equity Tier 1 minimum capital requirement (4.5% of risk-weighted assets), a minimum Tier 1 capital to risk-based assets requirement (6% of risk-weighted assets) and assigns a risk weight (150%) to exposures that are more than 90 days past due or are on nonaccrual status and to certain commercial real estate facilities that finance the acquisition, development or construction of real property. The rules also require unrealized gains and losses on certain available-for-sale securities holdings to be included for purposes of calculating regulatory capital requirements unless a one-time opt-in or opt-out is exercised. In connection with the adoption of the Basel III Capital Rules, United Community and Home Savings elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1. The rule limits a banking organization’s capital distributions and certain discretionary bonus payments if the banking organization does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital risk-based weighted assets in addition to the amount necessary to meeting its minimum risk-based capital requirements. The capital conservation buffer requirement is being phased in through January 1, 2019, when the full capital conservation buffer requirement will be effective. The capital conservation buffer for 2017 was 1.25% and the capital conservation buffer for 2018 is 1.875%. The final rule also implemented consolidated capital requirements. Quantitative measures established by regulation for capital adequacy require Home Savings to maintain minimum ratios of Tier 1 (or Core) capital (as defined in the regulations) to average total assets (as defined) and of total risk-based capital (as defined) to risk-weighted assets (as defined). United Community and Home Savings’ Common Equity Tier 1 capital consists of common stock and related paid-in capital, net of treasury stock, and retained earnings. Common Equity Tier 1 for both United Community and Home Savings is reduced by intangible assets, net of associated deferred tax liabilities and subject to transition provisions. Actual and regulatory required capital ratios for Home Savings, along with the dollar amount of capital implied by such ratios, are presented below.

Postemployment Benefits [Abstract]
BENEFIT PLANS	17. BENEFIT PLANS Postretirement Benefit Plans In addition to Home Savings’ retirement plans, Home Savings sponsored a defined benefit health care plan that was curtailed in 2000 to provide postretirement medical benefits only for these employees who worked 20 years and attained a minimum age of 60 by September 1, 2000, while in service with Home Savings. That plan was curtailed again in 2015, and medical benefits are no longer provided to plan participants as of December 31, 2016. The curtailment resulted in a gain of $1.1 million recognized in salaries and employee benefits during 2015 and the recognition of unrealized gains as a reduction of salaries and employee benefits of $1.2 million during 2016. The plan was unfunded and, as such, had no assets. Furthermore, the plan was contributory and contained minor cost-sharing features such as deductibles and coinsurance. In addition, postretirement life insurance coverage was provided for employees who were participants prior to December 10, 1976. The life insurance plan was non-contributory. Home Savings’ policy was to pay premiums monthly, with no pre-funding. The life insurance portion of the plan was terminated and the plan was settled in the fourth quarter of 2016. The benefit obligation measurement date was December 31. Information about changes in obligations of the benefit plan follows: For the year ended December 31, 2016 (Dollars in thousands) Change in Benefit Obligation: Benefit obligation at beginning of year $ 333 Service cost — Net periodic benefit cost (benefit) (1,268 ) Actuarial gain 1,268 Benefits paid (333 ) Curtailment gain — Benefit obligation at end of the year — Funded status of the plan $ — Components of net periodic benefit cost/(benefit) were as follows: For the year ended December 31, 2016 2015 Service cost $ — $ — Interest cost 10 53 Expected return on plan assets — — Net amortization of prior service cost (benefit) (228 ) (228 ) Amortization of net actuarial gain (1,050 ) (86 ) Curtailment gain — (1,072 ) Net periodic benefit cost (1,268 ) (1,333 ) Net (gain) loss — (184 ) Prior service credit — — Amortization of prior service cost and net actuarial gain 1,278 315 Total recognized in other comprehensive income 1,278 131 Total recognized in net periodic benefit cost and other comprehensive income $ 10 $ (1,202 ) Assumptions used in the valuations were as follows: Weighted average discount rate 3.90 % 3.90 % 401(k) Savings Plan Home Savings sponsors a defined contribution 401(k) savings plan, which covers substantially all employees. Under the provisions of the plan, Home Savings’ matching contribution is discretionary and may be changed from year to year. For 2017, 2016 and 2015, Home Savings’ match was 50% of pretax contributions up to a maximum of 6%. Participants become 100% vested in Home Savings contributions upon completion of three years of service. For the years ended 2017, 2016 and 2015, the expense related to this plan was approximately $619,000, $480,000 and $465,000, respectively. Stock-based Compensation: Stock Options On April 30, 2015, shareholders approved the United Community Financial Corp. 2015 Long Term Incentive Compensation Plan (the 2015 Plan). The purpose of the 2015 Plan is to provide a means through which United Community may attract and retain employees and non-employee directors, to provide incentives that align their interest with those of United Community’s shareholders and promote the success of United Community’s business. All employees and non-employee directors are eligible to participate in the 2015 Plan. The 2015 Plan provides for the issuance of up to 1,200,000 shares that are to be used for awards of stock options, stock awards, stock units, stock appreciation rights, annual bonus awards and long-term incentive awards. On April 26, 2007, shareholders approved the United Community Financial Corp. 2007 Long-Term Incentive Plan (as amended, the 2007 Plan). The purpose of the 2007 Plan was to promote and advance the interests of United Community and its shareholders by enabling United Community to attract, retain and reward directors, directors emeritus, managerial and other key employees of United Community, including Home Savings, by facilitating their purchase of an ownership interest in United Community. The 2007 Plan was terminated on April 30, 2015 upon the adoption of the 2015 Plan, although the 2007 Plan survives so long as awards issued under the 2007 Plan remain outstanding and exercisable. The 2007 Plan provided for the issuance of up to 2,000,000 shares that were to be used for awards of restricted stock, stock options, performance awards, stock appreciation rights (SARs), or other forms of stock-based incentive awards. On July 12, 1999, shareholders approved the United Community Financial Corp. 1999 Long-Term Incentive Plan (as amended, the 1999 Plan). The purpose of the 1999 Plan was the same as the 2007 Plan. The 1999 Plan terminated on May 20, 2009, although the 1999 Plan survives so long as options issued under the 1999 Plan remain outstanding and exercisable. The 1999 Plan provided for the grant of either incentive or nonqualified stock options. Options were awarded at exercise prices that were not less than the fair market value of the share at the grant date. The maximum number of common shares that could be issued under the 1999 Plan was 3,569,766. Because the 1999 Plan terminated, no additional options may be issued under it. All of the options awarded became exercisable on the date of grant except that options granted in 2009 became exercisable over three years beginning on December 31, 2009. All options expire 10 years from the date of grant. There were no stock options granted in 2017 and 2016 and there were 6,618 stock options granted in 2015. The options must be exercised within 10 years from the date of grant. Expenses related to stock option grants are included with salaries and employee benefits. All of the Company’s stock options are vested at December 31, 2017. The Company recognized $1,000 and $9,000, in stock option expense for the twelve months ended December 31, 2017 and 2016, respectively. A summary of activity in the plans is as follows: For the year ended December 31, 2017 Shares Weighted average exercise price Aggregate intrinsic value (Dollars in thousands) Outstanding at beginning of year 371,218 $ 2.55 Granted — — Exercised (110,085 ) 2.53 Forfeited (600 ) 2.10 Outstanding at end of period 260,533 2.55 $ 1,697 Options exercisable at end of period 260,533 2.55 1,697 Information related to the stock options granted and exercised during each year follows: 2017 2016 2015 Intrinsic value of options exercised $ 702,000 $ 883,000 $ 48,000 Cash received from option exercises 279,000 517,000 28,000 Tax benefit realized from option exercises 120,000 82,000 — Weighted average fair value of options granted — — 1.70 There were no options granted in 2017 and 2016. The fair value of options granted in 2015 was determined using the following weighted-average assumptions as of the grant date: 2015 Risk-free interest rate 1.49 % Expected term (years) 5 Expected stock volatility 35.95 % Dividend yield 0.74 % Outstanding stock options have a weighted average remaining life of 2.56 years and may be exercised in the range of $1.20 to $5.89. Stock-based Compensation: Restricted Stock Awards The 2015 and 2007 Plans permit the issuance of restricted stock awards to employees and nonemployee directors. Nonvested shares at December 31, 2017 aggregated 277,035, of which 135,635 will vest in 2018, 107,260 will vest in 2019 and 34,140 will vest in 2020. Expenses related to restricted stock awards are charged to salaries and employee benefits and are recognized over the vesting period of the awards based on the market value of the shares at the grant date. The Company recognized approximately $951,000, $970,000 and $756,000 in restricted stock award expenses, including expenses for shares issued under the annual incentive plan, for the twelve months ended December 31, 2017, 2016 and 2015, respectively. The Company expects to recognize additional expenses of approximately $784,000 in 2018, $362,000 in 2019, and $154,000 in 2020. A summary of changes in the Company’s nonvested restricted shares for the year is as follows: Shares Weighted average exercise price Nonvested shares at January 1, 2017 341,184 $ 5.50 Granted 88,681 8.77 Vested (152,830 ) 5.20 Forfeited — — Nonvested shares at December 31, 2017 277,035 6.73 The total average per share fair value of shares vested during the years ended December 31, 2017, 2016 and 2015 was $8.61, $5.97 and $5.48, respectively. Annual Incentive Plan The Annual Incentive Plan (“AIP”) provides incentive compensation awards to certain officers of the Company. The incentive awards are based upon the actual performance of the Company, and personal performance for the twelve months ending December 31, compared to the actual performance of a peer group and plan during the same twelve month period. The target incentive awards for each year are measured as a percentage of the base salary of participating officers. Once the awards under the AIP are calculated, they are paid either in cash or 80% cash and 20% restricted stock, depending on the particpant. The restricted stock granted will vest equally over three years, beginning on the first anniversary of the date the restricted stock is issued. The Company incurred $315,000, $356,000 and $269,000 in expense for the restricted stock portion of the AIP and $1.7 million, $1.3 million and $804,000 for the cash portion of the AIP for the twelve months ended December 31, 2017, 2016 and 2015, respectively. Restricted stock expenses for the AIP are included in the total restricted stock expenses discussed above. Long-Term Incentive Plan The Long-Term Incentive Plan (“LTIP”) provides a long-term incentive compensation opportunity to certain executive officers. Each participant in the LTIP will be granted a target number of Performance Share Units (“PSUs”). Target PSUs will be determined as a percentage of base salary and translated into share units based on the Company’s average stock price at the appropriate measurement date. The performance period for the annual grant for a given year will be from January 1, year 1 through December 31, year 3. The Company incurred $230,000, $693,000 and $199,000 in expense for the LTIP for the twelve months ended December 31, 2017, 2016 and 2015, respectively. The increase in expense for 2016 was driven by the rise in United Community’s share price during the performance period.

Fair Value Disclosures [Abstract]
FAIR VALUE	18. FAIR VALUE Fair value is the exchange price that would be received for an asset if paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own beliefs about the assumptions that market participants would use in pricing an asset or liability. United Community uses the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Available for sale securities: The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2), using matrix pricing. Matrix pricing is a mathematical technique commonly used to price debt securities that are not actively traded, values debt securities without relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). Impaired loans: At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Impaired loans carried at fair value generally receive specific allocations of the allowance for loan losses. For collateral dependent loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Other real estate owned: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Real estate owned properties are individually evaluated at least annually for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by Home Savings. Once received, a member of the Special Assets Department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with the independent data sources such as recent market data or industry-wide statistics. On an annual basis, Home Savings compares the actual selling price of collateral that has been sold to the most recent appraised value to determine what additional adjustment should be made to the appraisal value to arrive at fair value. At the time a property is acquired and classified as real estate owned, the fair value is determined utilizing the most appropriate method. A fair value in excess of $250,000 will be supported by an appraisal. After determination of fair value, each property will be recorded at the lower of cost (i.e., recorded investment in the loan) or the estimated net realizable value on the date of transfer to real estate owned. In determining net realizable value, reductions to fair market value may be taken for estimated costs of sale, conditions that must be remedied immediately upon acquisition, and other factors that negatively impact the marketability and prompt sale of the property. Mortgage servicing rights: On a quarterly basis, loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. If the carrying amount of an individual tranche exceeds fair value, impairment is recorded on that tranche so that the servicing asset is carried at fair value. Fair value is determined at a tranche level, based on market prices for comparable mortgage servicing contracts (Level 2), when available, or alternatively based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model utilizes assumptions that market participants would use in estimating future net servicing income and that can be validated against available market data (Level 2). Loans held for sale: Loans held for sale for which the fair value option has not been elected are carried at the lower of cost or fair value, which is evaluated on a pool-level basis. The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2). Loans held for sale, at fair value : The Company elected the fair value option for all conventional residential one-to four-family loans held for sale originated after January 1, 2016 and all permanent construction loans held for sale originated after January 1, 2015. The fair value of conventional loans held for sale is determined using the current 15 day forward contract price for either 15 or 30 year conventional mortgages and the 60 day forward contract price for either 15 or 30 year Federal Housing Authority mortgages (Level 2). The fair value of permanent construction loans held for sale is determined using the current 60 day forward contract price for 30 year conventional mortgages which is then adjusted by extrapolating this rate to the estimated time period remaining until construction is complete. The fair value is also adjusted for unobservable market data such as estimated fall out rates and the estimated time from origination to completion of construction (Level 3). Interest rate caps: Home Savings interest rate caps matured in the fourth quarter of 2016. Home Savings used an independent third party that performs a market valuation analysis for interest rate caps. The methodology used consisted of a discounted cash flow model, all future floating cash flows were projected and both floating and fixed cash flows were discounted to the valuation date. The yield curve utilized for discounting and projecting was built by obtaining publicly available third party market quotes from Reuters, which handle up to 30-year swap maturities (Level 3) Assumptions used in the valuation of interest rate caps were back-tested for reasonableness on a quarterly basis using an independent source along with a third party service. Purchased and written certificate of deposit option: Home Savings periodically enters into written and purchased option derivative instruments to facilitate the Power CD. The written and purchased options are mirror derivative instruments which are carried at fair value on the consolidated balance sheets. Home Savings uses an independent third party that performs a market valuation analysis for purchased and written certificate of deposit options. (Level 2) Assets and Liabilities Measured on a Recurring Basis: Assets and liabilities measured at fair value on a recurring basis are summarized below: Fair Value Measurements at December 31, 2017 Using: Quoted Significant Prices in Unobservable Active Significant Inputs Markets for Other Significant Identical Observable Unobservable December 31, Assets Inputs Inputs 2017 (Level 1) (Level 2) (Level 3) (Dollars in thousands) Assets: Available for sale securities US Treasury and government sponsored entities’ securities $ 123,817 $ — $ 123,817 $ — States of the U.S. and political subdivisions 59,623 — 59,623 — Mortgage-backed GSE securities: residential 87,121 — 87,121 — Loans held for sale, at fair value 83,541 — 18,525 65,016 Purchased certificate of deposit option 809 — 809 — Liabilities Written certificate of deposit option 809 — 809 — Fair Value Measurements at December 31, 2016 Using: Quoted Significant Prices in Unobservable Active Significant Inputs Markets for Other Significant Identical Observable Unobservable December 31, Assets Inputs Inputs 2016 (Level 1) (Level 2) (Level 3) (Dollars in thousands) Assets: Available for sale securities US Treasury and government sponsored entities’ securities $ 186,033 $ — $ 186,033 $ — States of the U.S. and political subdivisions 57,757 — 57,757 — Mortgage-backed GSE securities: residential 99,494 — 99,494 — Loans held for sale, at fair value 62,593 — 8,832 53,761 Purchased certificate of deposit option 882 — 882 — Liabilities Written certificate of deposit option 882 — 882 — There were no transfers between Level 1 and Level 2 during 2017 and 2016.

There were no transfers between Level 2 and Level 3 during 2017 or 2016. The following table presents quantitative information about recurring Level 3 fair value measurements at December 31, 2017: Fair Value Valuation Technique Unobservable Inputs Range (Dollars in thousands) Construction loans held for sale $ 65,016 Comparable sales Time discount using the 60 day forward contract 0.00%-1.96% The following table presents quantitative information about recurring Level 3 fair value measurements at December 31, 2016: Fair Value Valuation Technique Unobservable Inputs Range (Dollars in thousands) Construction loans held for sale $ 53,761 Comparable sales Time discount using the 60 day forward contract 0.00%-1.80% The significant unobservable inputs used in the fair value measurement of interest rate caps was determined using proprietary models from third-party sources taking into account such factors as size of the transaction, the lack of a quoted market and the custom-tailored nature of the transaction. The fair value is inclusive of interest accruals, as applicable. Significant increases/(decreases) in any of those inputs in isolation would result in a significantly lower/(higher) fair value measurement. Assets Measured on a Non-Recurring Basis Assets measured at fair value on a non-recurring basis are summarized below: Fair Value Measurements at December 31, 2017 Using: Quoted Significant Prices in Unobservable Active Significant Inputs Markets for Other Significant Identical Observable Unobservable December 31, Assets Inputs Inputs 2017 (Level 1) (Level 2) (Level 3) (Dollars in thousands) Assets: Impaired loans Commercial loans Multifamily $ 247 $ — $ — $ 247 Nonresidential 2 — — 2 Secured 40 — — 40 Residential loans One-to four-family residential 1,010 — — 1,010 Consumer loans Home Equity 89 — — 89 Auto 13 — — 13 Marine 169 — — 169 Recreational vehicle 86 — — 86 Mortgage servicing rights 382 — 382 — Other real estate owned, net Commercial loans Construction loans 354 — — 354 Residential loans One-to four-family residential 82 — — 82 Fair Value Measurements at December 31, 2016 Using: Quoted Significant Prices in Unobservable Active Significant Inputs Markets for Other Significant Identical Observable Unobservable December 31, Assets Inputs Inputs 2016 (Level 1) (Level 2) (Level 3) (Dollars in thousands) Assets: Impaired loans Commercial loans Nonresidential $ 2,257 $ — $ — $ 2,257 Secured 284 — — 284 Residential loans One-to four-family residential 919 — — 919 Consumer loans Home Equity 228 — — 228 Auto 177 — — 177 Recreational vehicle 89 — — 89 Other real estate owned, net Commercial loans Construction loans 748 — — 748 Residential loans One-to four-family residential 281 — — 281 Impaired loans with specific allocations of the allowance for loan losses, carried at fair value, which are measured for impairment using the fair value of the collateral for collateral dependent loans, had a net carrying amount of $1.7 million at December 31, 2017, that includes a specific valuation allowance of $491,000. This resulted in an increase of the provision for loan losses of $938,000 during the twelve months ended December 31, 2017. Impaired loans with specific allocations of the allowance for loan losses, carried at fair value, which are measured for impairment using the fair value of the collateral for collateral dependent loans, had a net carrying amount of $4.0 million at December 31, 2016, that includes a specific valuation allowance of $1.3 million. This resulted in an increase of the provision for loan losses of $4.1million during the twelve months ended December 31, 2016. The significant unobservable (Level 3) inputs used in the fair value measurement of collateral for collateral dependent impaired loans included in the above table primarily relate to the adjustment between carrying value versus appraised value. During the reported periods, discounts applied to appraisals for estimated selling costs were 10%. At December 31, 2017, mortgage servicing rights that were carried at fair value was $382,000, resulting in additional expense of $9,000 for the year ended December 31, 2017. At December 31, 2016, no mortgage servicing rights were carried at fair value, resulting in a net recovery of $39,000 for the year ended December 31, 2016. Mortgage servicing rights are valued by an independent third party that is active in purchasing and selling these instruments. The value reflects the characteristics of the underlying loans discounted at a market multiple. At December 31, 2017, other real estate owned, carried at fair value, which is measured for impairment using the fair value of the property less estimated selling costs and had a net carrying amount of $436,000 that includes a valuation allowance of $403,000. This resulted in additional expenses of $37,000 during the twelve months ended December 31, 2017. At December 31, 2016, other real estate owned, carried at fair value, which is measured for impairment using the fair value of the property less estimated selling costs and had a net carrying amount of $1.0 million, with a valuation allowance of $1.0 million. This resulted in a recovery of expenses of $16,000 during the twelve months ended December 31, 2016.

These loans are intended for sale and the Company believes that the fair value is the best indicator of the resolution of these loans. Interest income is recorded based on the contractual terms of the loan and in accordance with the Company’s policy on loans held for investment. None of these loans are 90 days or more past due nor on nonaccrual as of December 31, 2017 and 2016.

The carrying value and estimated fair values of financial instruments at December 31, 2017 and December 31, 2016, were as follows: Fair Value Measurements at December 31, 2017 Using: December 31, 2017 Carrying Value (Level 1) (Level 2) (Level 3) (Dollars in thousands) Assets: Cash and cash equivalents $ 46,880 $ 46,880 $ — $ — Available for sale securities 270,561 — 270,561 — Held to maturity securities 82,911 — 82,126 — Loans held for sale at lower of cost or market 211 — 217 — Loans held for sale at fair value 83,541 — 18,525 65,016 Loans, net 1,999,877 — — 1,990,289 FHLB stock 19,324 n/a n/a n/a Accrued interest receivable 8,190 — 2,244 5,946 Purchased certificate of deposit option 809 — 809 — Liabilities: Deposits: Checking, savings and money market accounts (1,251,398 ) (1,251,398 ) — — Certificates of deposit (705,341 ) — (705,238 ) — FHLB advances (356,536 ) — (356,521 ) — Repurchase agreements and other (197 ) — (190 ) — Advance payments by borrowers for taxes and insurance (25,038 ) (25,038 ) — — Accrued interest payable (1,097 ) — (1,097 ) — Written certificate of deposit option (809 ) — (809 ) — Fair Value Measurements at December 31, 2016 Using: December 31, 2016 Carrying Value (Level 1) (Level 2) (Level 3) (Dollars in thousands) Assets: Cash and cash equivalents $ 45,887 $ 45,887 $ — $ — Available for sale securities 343,284 — 343,284 — Held to maturity securities 97,519 — 92,940 3,210 Loans held for sale at lower of cost or market 165 — 169 — Loans held for sale at fair value 62,593 — 8,832 53,761 Loans, net 1,503,577 — — 1,494,534 FHLB stock 18,068 n/a n/a n/a Accrued interest receivable 6,900 — 2,624 4,276 Purchased certificate of deposit option 882 — 882 — Liabilities: Deposits: Checking, savings and money market accounts (1,026,565 ) (1,026,565 ) — — Certificates of deposit (488,426 ) — (491,278 ) — FHLB advances (390,756 ) — (390,750 ) — Repurchase agreements and other (512 ) — (513 ) — Advance payments by borrowers for taxes and insurance (23,812 ) (23,812 ) — — Accrued interest payable (145 ) — (145 ) — Written certificate of deposit option (882 ) — (882 ) — The methods and assumptions, not previously presented, used to estimate fair values are described as follows: (a) Cash and Cash Equivalents The carrying amounts of cash and short-term instruments approximate fair values and are classified as Level 1. (b) FHLB Stock It is not practical to determine the fair value of FHLB stock due to restrictions placed on its transferability. (c) Held to maturity securities Fair values for held to maturity securities are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments. For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows. (d) Loans Fair values of loans, excluding loans held for sale, are estimated as follows: For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values resulting in a Level 3 classification. Fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. (e) Deposits The fair values disclosed for demand deposits (e.g., interest and non-interest checking, savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in a Level 1 classification. The carrying amounts of variable rate, fixed-term money market accounts approximate their fair values at the reporting date resulting in a Level 1 classification. Fair values for fixed and variable rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates of deposit to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. (f) Short-term Borrowings The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within 90 days, approximate their fair values resulting in a Level 2 classification. (g) Other Borrowings The fair values of Home Savings long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. (h) Accrued Interest Receivable/Payable The carrying amounts of accrued interest approximate fair value resulting in a Level 2 or Level 3 classification, depending on the classification of the underlying asset or liability. (i) Off-balance Sheet Instruments Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of commitments is not material.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives	20. DERIVATIVES Home Savings utilizes interest rate cap agreements as part of its asset/liability management strategy to help manage its interest rate risk position. Home Savings entered into an interest rate cap agreement in October 2011 with an outside counterparty. Home Savings receives proceeds from the counterparty if interest rates exceed the cap rate computed based on the underlying notional amounts. The notional amount of the interest rate caps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate cap agreements. The interest rate caps are carried as freestanding derivatives, considered an economic hedge and classified as an other asset with a carrying value of $0 at December 31, 2017 and $0 at December 31, 2016 with changes in fair value of approximately $0, $(3,000) and $(177,000) during 2017, 2016 and 2015 reported in current earnings through other noninterest income. Home Savings periodically enters into written and purchased option derivative instruments to facilitate an equity linked time deposit product (the Power CD). The Power CD is a time deposit that provides the purchaser a guaranteed return of principal at maturity plus a potential equity return (a written option), while Home Savings receives a known stream of funds based on the equity return (a purchased option). The written and purchased options are mirror derivative instruments which are carried at fair value on the consolidated statements of financial condition. Summary information about purchased and written options is as follows: December 31, 2017 December 31, 2016 (Dollars in thousands) Notional amount of purchased/written option $ 13,405 $ 13,789 Weighted average maturity 2.6 years 3.9 years Fair value of purchased/written option $ 809 $ 882 Purchased and written options are mirror derivative instruments and as such the changes in fair value are recorded through noninterest income, and offset each other. These options decreased in value $79,000 in 2017 and increased in value by $77,000 in 2016. The following table reflects the fair value and location in the consolidated statement of financial condition of interest rate caps, along with purchased and written certificates of deposit options: Included in other assets: December 31, 2017 December 31, 2016 (Dollars in thousands) Freestanding derivative assets not designated as hedges: Purchased certificate of deposit option $ 809 $ 882 Included in other liabilities: December 31, 2017 December 31, 2016 (Dollars in thousands) Freestanding derivative liabilities not designated as hedges: Written certificate of deposit option $ 809 $ 882 Home Savings is subject to counterparty risk. Counterparty risk is the risk to Home Savings that the counterparty will not live up to its contractual obligations. The ability of Home Savings to realize the benefit of the derivative contracts is dependent on the creditworthiness of the counterparty, which Home Savings expects will perform in accordance with the terms of the contracts.

During the fourth quarter 2017, the Company recognized a $2.3 million other asset impairment charge. In 2003, Home Savings entered into two development loans on which the borrower subsequently filed bankruptcy, and a Court appointed receiver liquidated the collateral. The proceeds from the sale of the collateral have remained in escrow with the Court since 2007 as a number of competing claims were made against the proceeds. In 2011, a lower court affirmed Home Savings' priority position in the proceeds, and its lien validity was affirmed by the same Court in 2016. However, in December 2017, an Appellate Court ruled that a portion of the proceeds should be awarded to another claimant. The $2.3 million charge reflects the Appellate court ruling. It is the Company’s intent to continue to pursue a full recovery. 3.

SUMMARY OF SIGNIFICANT ACCOUN34

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Nature of Operations	Nature of Operations The business of Home Savings is providing consumer and business banking service to its market area in Ohio, western Pennsylvania and West Virginia. At the end of 2017, Home Savings was doing business through 35 full service banking branches and 13 loan production centers and three wealth management offices. Loans and deposits are primarily generated from the areas where banking branches are located. Substantially all loans are secured by specific items of collateral including business assets, consumer assets, and commercial and residential real estate. Commercial loans are expected to be repaid from cash flow from operations of businesses. There are no significant concentrations of loans to any one industry or customer. However, the customers’ ability to repay their loans is dependent on the real estate and general economic conditions in the market area. Home Savings derives its income predominantly from interest on loans, securities, and to a lesser extent, non-interest income. Home Savings’ principal expenses are interest paid on deposits and Federal Home Loan Bank advances, loan loss provisions and normal operating costs. On January 29, 2016, United Community acquired James & Sons Insurance. James & Sons Insurance was merged into HSB Insurance, LLC, a wholly-owned subsidiary of United Community. HSB Insurance, LLC d/b/a James & Sons Insurance is an insurance agency that offers a wide variety of insurance products for business and residential customers, which include auto, homeowners, life-health, commercial, surety bonds and aviation. On February 28, 2017, James & Sons Insurance acquired Eich Brothers Insurance. Eich Brothers Insurance is an insurance agency that offers insurance products for business and residential customers, which include auto, commercial, homeowners and life-health. On July 1, 2017, James & Sons Insurance acquired Stevens Insurance Agency that offers insurance products for business and residential customers, which include auto, commercial, homeowners and life-health. HSB Capital, LLC was formed by United Community during 2016 for the purpose of providing mezzanine funding for customers. Mezzanine loans are offered to customers in United Community’s market area and are expected to be repaid from the cash flow from operations of the business. HSB Insurance, Inc., a wholly-owned subsidiary of the Company which was formed and began operations on June 1, 2017, is a Delaware-based captive insurance company which insures against certain risks unique to the operations of the Company and its subsidiaries and for which insurance may not be currently available or economically feasible in today’s insurance marketplace. HSB Insurance, Inc. pools resources with several other insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. HSB Insurance, Inc. is subject to regulations of the State of Delaware and undergoes periodic examinations by the Delaware Division of Insurance.
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of United Community and its subsidiaries. All material inter-company transactions have been eliminated. Certain prior period data has been reclassified to conform to current period presentation. These reclassifications had no effect on prior net income or shareholders’ equity.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ.
Cash Flows	Cash Flows For purposes of the statement of cash flows, United Community considers all highly liquid investments with a term of three months or less to be cash equivalents. Net cash flows are reported for loan and deposit transactions, short-term borrowings and advance payments by borrowers for taxes and insurance.
Securities	Securities Securities are classified as available for sale, held to maturity or trading upon their acquisition. Securities are classified as available for sale when they might be sold before maturity. Securities classified as available for sale are carried at estimated fair value with the unrealized holding gain or loss reported in other comprehensive income, net of tax. Securities classified as held to maturity are carried at amortized cost when management has the positive intent and ability to hold them to maturity. Equity securities with readily determinable fair values are classified as available for sale. Restricted securities such as FHLB stock are carried at cost. Interest income includes amortization of purchase premium or discount on debt securities. Premiums or discounts are amortized on the level-yield method without anticipating prepayments. Gains and losses on sales are recorded on the trade date and are determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (OTTI) at least quarterly, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of OTTI is recognized through earnings.
Loans Held for Sale	Loans Held for Sale Loans held for sale primarily consist of residential mortgage loans originated for sale and other loans that have been identified for sale. If the fair value option has not been elected, the loans are carried at the lower of cost or fair value, determined in the aggregate. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Loans held for sale, for which the fair value option has been elected, are recorded at fair value as of each balance sheet date with the change in fair value recorded in earnings. The fair value of the Company’s construction perm loans held for sale is determined based on quoted prices for similar loans in active markets. The fair value of permanent construction loans held for sale is determined, based on the committed loan amount, using quoted prices for similar assets, adjusted for specific attributes of that loan and other unobservable market data, such as time it takes to complete the project. The fair value of conventional residential one-to four-family loans held for sale which the fair value option has been elected is determined based on quoted prices for similar loans in active markets. Since January 1, 2016, the Company elected the fair value option for all loans originated and held for sale. Mortgage loans held for sale are sold with either servicing rights retained or servicing released. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing right. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the outstanding principal balance, net of purchase premiums or discounts, deferred loan fees and costs and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Interest income includes amortization of net deferred loan fees and costs. Loan fees and costs associated with origination of loans are deferred and amortized to interest income over the contractual lives of the loans using the level yield method. Fees received for loan commitments that are expected to be drawn, based on Home Savings’ experience with similar commitments, are deferred and amortized over the lives of the loans using the level-yield method. Fees for other loan commitments are deferred and amortized over the loan commitment period on a straight-line basis. Unamortized deferred loan fees or costs related to loans paid off are included in income. Unamortized net fees or costs on loans sold are included in the basis of the loans in calculating gains and losses. The accrual of interest income and amortization of net deferred fees on mortgage and commercial loans is discontinued at the time the loan is 90 days delinquent unless the loan is both well secured and in the process of collection. Consumer loans are typically charged-off no later than 180 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. All interest accrued but not received for a loan placed on nonaccrual is reversed against interest income. Once a loan is on nonaccrual, it will remain on nonaccrual until the loan becomes current and the borrower demonstrates the ability to pay the loan per the contractual terms for a minimum of six months. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. Loans are returned to accrual status when future payments are reasonably assured. Home Savings determines the past due status of loans based on the number of calendar months the loan is past due. Impaired loans consist of loans that are non-homogenous and in a nonaccrual status; loans considered troubled debt restructurings and loans that have been individually analyzed for impairment. Residential mortgage loans. Residential mortgage loans are revalued at the time they reach 180 days past due and any portion of the principal that exceeds the fair value is charged-off. Mortgage loans are considered to be homogenous until the loan is individually evaluated at 180 days past due and charged-down to the fair value of the underlying collateral, at which time the loan becomes non-homogenous and is considered impaired. Residential mortgage loans that have been modified and determined to be a troubled debt restructuring (TDR) are revalued based upon the present value of the modified cash flows of the loan to establish a specific reserve on that loan. Consumer loans. Consumer loans that are secured by residential real estate are revalued once they reach 180 days past due and charged-down to the fair value if necessary. Consumer loans that are not secured by residential real estate are revalued once they reach 120 days past due and are charged-down to the fair value if necessary. Consumer loans are considered to be homogenous until the loan is individually evaluated and charged-down to the fair value of the underlying collateral, at which time the loan becomes non-homogenous and is considered impaired. Consumer loans that have been modified and determined to be a TDR are revalued based upon the present value of the modified cash flows of the loan to establish a specific reserve on that loan. Commercial loans. A commercial real estate loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. At this time, the loan is charged-down to the fair value. Commercial and industrial loans are impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. The repayment of commercial loans typically is dependent on the income stream and successful operation of a business. If there is no underlying collateral to value, the company will calculate the present value of expected future cash flows to determine the amount of impairment, if any.
Concentration of Credit Risk	Concentration of Credit Risk Most of the Company’s business activity is with customers located within Home Savings’ market area. Therefore, the Company’s exposure to credit risk is significantly affected by changes in the economy in Ohio, Western Pennsylvania and Northern West Virginia.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required based on an analysis using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations, estimated collateral values, general economic conditions in the market area and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired or loans otherwise classified as substandard or doubtful. The general component covers non-classified loans and is based on historical loss experience adjusted for current factors. Other loans not reviewed specifically by management are evaluated as a homogenous group of loans (generally single-family residential mortgage loans and all consumer credits except marine loans) using a loss factor applied to the outstanding loan balance to determine the level of reserve required. This loss factor consists of two components, a quantitative and a qualitative component. The quantitative component is based on a historical analysis of all charged-off loans, net of recoveries, looking back 22 quarters as of December 31, 2017. In determining the qualitative component, consideration is given to such attributes as lending policies, economic conditions, nature and volume of the portfolio, management, loan quality trend, loan review, collateral value, concentrations, economic cycles and other external factors. The quantitative and qualitative components are combined to arrive at the loss factor, which is applied to the average outstanding balance of homogenous loans. At December 31, 2016, the Company evaluated 18 quarters of net charge-off history. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans are individually evaluated based on the borrower’s ability to repay the loan given the availability of collateral, other sources of cash flow and legal options available to Home Savings. Once a review is completed, a specific reserve is determined and allocated to the loan. These specific reserves on individual loans are reviewed periodically and adjusted as necessary based on subsequent collection, loan upgrades or downgrades, nonperforming trends or actual principal charge-offs. Loans for which the terms have been modified, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the facts and circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent. Troubled debt restructurings (TDRs) are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For TDRs that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The Bank’s portfolio has the following segments: commercial, which includes commercial real estate secured loans, residential mortgage loans and consumer loans. Residential mortgage loans are made to customers in Home Savings’ market area. These loans are secured by the underlying real estate as collateral. Repayment of these loans is dependent on general economic conditions and unemployment levels in Home Savings’ market area. To reduce any risk on loans secured by one-to four-family residences, Home Savings underwrites all portfolio loans to Freddie Mac underwriting guidelines. Consumer loans primarily consist of home equity loans and lines of credit. Similar to residential mortgage loans, repayment of consumer loans depends on the general economic conditions and unemployment levels in Home Savings’ market area. The majority of Home Savings’ consumer loans consist of closed-end home equity loans and lines of credit in an amount that, when added to the prior indebtedness secured by the real estate, does not exceed 90% of the estimated value of the real estate. Other consumer loans, such as automobiles and recreational vehicles, have a higher degree of risk than home equity loans as the collateral depreciates at a faster rate. Multifamily and nonresidential real estate loans generally have a higher degree of risk than loans secured by one-to four-family residences. These riskier loans can be affected by economic conditions, operating expenses, debt service and successful operation of income-producing properties. Home Savings tries to reduce this risk by evaluating the credit history of the borrower, location of the real estate, the financial condition of the borrower, obtaining personal guarantees of the principals, the characteristics of the income stream generated by the property and the appraisal supporting the property. Commercial loans generally entail greater risk than real estate lending. The repayment of commercial loans typically is dependent on the income stream and successful operation of a business, which can be affected by economic conditions. The collateral for commercial loans, if any, often consists of rapidly depreciating assets. Construction loans involve a higher degree of underwriting and default risk than loans secured by mortgages on existing properties because construction loans are more difficult to appraise and to monitor. Loan funds are advanced based upon the status of the project under construction.
Servicing Assets	Servicing Assets Servicing assets are recognized as separate assets when rights are acquired through the purchase or sale of financial assets. Servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. Capitalized servicing rights are reported in other assets and are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying assets. Servicing assets are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is determined by stratifying rights into tranches based on predominant risk characteristics, such as original maturity, interest rate and loan type. Impairment is recognized through a valuation allowance for an individual tranche. If Home Savings later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal, or a fixed amount per loan, and are recorded as income when earned. The amortization of mortgage servicing rights is shown separately in non-interest income.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Real Estate Owned and Other Repossessed Assets	Real Estate Owned and Other Repossessed Assets Real estate owned, including property acquired in settlement of foreclosed loans, is initially transferred at fair value less estimated cost to sell after foreclosure, establishing a new cost basis. Physical possession of residential real estate property collateralizing a residential mortgage loan occurs when legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines after acquisition, a valuation allowance is recorded through expense. Costs relating to the development and improvement of real estate owned are capitalized, whereas costs relating to holding and maintaining the properties are charged to expense. Other repossessed assets are carried at estimated fair value less estimated cost to sell after acquisition.
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation and amortization. Buildings and related components are depreciated and amortized using the straight-line method over the useful lives, generally ranging from 20 years to 40 years (or term of the lease, if shorter) of the related assets. Furniture and fixtures are depreciated using the straight-line method with useful lives ranging from three to five years.
Federal Home Loan Bank (FHLB) stock	Federal Home Loan Bank (FHLB) stock The Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Cash Surrender Value of Life Insurance	Cash Surrender Value of Life Insurance Life insurance is carried on the lives of certain employees where Home Savings is the beneficiary. Life insurance is recorded at its cash surrender value, or the amount currently realizable. Increases in the Home Savings’ policy cash surrender value are tax exempt and death benefit proceeds received by Home Savings are tax-free. Income from these policies and changes in the cash surrender value are recorded in other income. The policies contain no split dollar or postretirement benefits for covered employees.
Goodwill and Other Intangible Assets	Goodwill and other Intangible Assets Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interest in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. The Company has selected December 31 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consist of core deposit and customer list intangibles. Core deposit intangible assets arose from whole bank acquisitions. They were initially measured at fair value and are being amortized on an accelerated method over their estimated useful lives. Customer list intangible arose from the acquisition of James & Sons Insurance in January 2016 and Premier Bank and Trust in January 2017 and are amortized on an accelerated basis over its estimated useful life of 10 years. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.
Derivatives	Derivatives At the inception of a derivative contract, the Company designates the derivative as one of three types based on the Company’s intentions and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), or (3) an instrument with no hedging designation (“stand-alone derivative”). For a fair value hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair values change. For a cash flow hedge, the gain or loss on the derivative is reported in other comprehensive income and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For both types of hedges, changes in the fair value of derivatives that are not highly effective in hedging the changes in fair value or expected cash flows of the hedged item are recognized immediately in current earnings. Changes in the fair value of derivatives that do not qualify for hedge accounting are reported currently in earnings, as noninterest income. Net cash settlements on derivatives that qualify for hedge accounting are recorded in interest income or interest expense, based on the item being hedged. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in noninterest income. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged. The Company formally documents the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions at the inception of the hedging relationship. This documentation includes linking fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in fair values or cash flows of the hedged items. The Company discontinues hedge accounting when it determines that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended. When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded as noninterest income. When a fair value hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a cash flow hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income are amortized into earnings over the same periods which the hedged transactions will affect earnings. In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.
Mortgage Banking Derivatives	Mortgage Banking Derivatives Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest rate on the loan is locked. The Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into in order to hedge the change in interest rates resulting from its commitments to fund the loans. Changes in the fair values of these derivatives are included in mortgage banking income on the consolidated statements of operations and comprehensive income.
Long-term Assets	Long-term Assets Premises and equipment and other long–term assets are reviewed for impairment when events indicate their carrying amounts may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value.
Stock Compensation	Stock Compensation Compensation cost is recognized for stock options and restricted stock awards issued to employees and nonemployee directors, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Corporation’s common shares at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, Compensation - Stock Compensation. In May 2017, the FASB issued ASU No. 2017-09 , Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting . ASU 2017-09 applies to entities that change the terms or conditions of a share-based payment award. The FASB adopted ASU 2017-09 to provide clarity and reduce diversity in practice as well as cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation , to the modification of the terms and conditions of a share-based payment award. The amendments in ASU 2017-09 These amendments require the entity to account for the effects of a modification unless all of the following conditions are met: • The fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or value using an alternative measurement method) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; • The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and • The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period for. The amendments should be applied prospectively to an award modified on or after the adoption date. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.
Income Taxes	Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.
401(k) Savings Plan	401(k) Savings Plan Employee 401(k) and profit sharing plan expense is the amount of matching contributions and administrative costs to administer the plan.
Postretirement Benefit Plans	Postretirement Benefit Plans In addition to Home Savings’ retirement plans, Home Savings sponsored a defined benefit health care plan that was curtailed in 2000 to provide postretirement medical benefits for employees who worked 20 years and attained a minimum age of 60 by September 1, 2000, while in service with Home Savings. That modified plan was further curtailed in 2015, and medical benefits are no longer provided to plan participants as of December 31, 2016 and the plan was terminated and settled. The plan was unfunded and, as such, had no assets. Furthermore, the plan was contributory and contained minor cost-sharing features such as deductibles and coinsurance. In addition, postretirement life insurance coverage was provided for employees who were participants prior to December 10, 1976. The life insurance plan was non-contributory. Home Savings’ policy was to pay premiums monthly, with no pre-funding. This plan was terminated and settled with participants in 2016. The benefit obligation was measured annually by a third-party actuary.
Dividend Restriction	Dividend Restriction Banking regulations require maintaining certain capital levels and may limit the dividends paid by the bank to the holding company or by the holding company to shareholders.
Earnings Per Share	Earnings Per Share Basic earnings per common share is net income available to common shareholders divided by the weighted average number of common shares outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options. In July 2017, the FASB ASU No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815) : (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. ASU 2017-11 simplifies the accounting for certain financial instruments with down round features, a provision in an equity-linked financial instrument (or embedded feature) that provides a downward adjustment of the current exercise price based on the price of future equity offerings. The new ASU will require companies to disregard the down round feature when assessing whether the instrument is indexed to its own stock, for purposes of determining liability or equity classification. Companies that provide earnings per share (EPS) data will adjust their basic EPS calculation for the effect of the feature when triggered (i.e., when the exercise price of the related equity-linked financial instrument is adjusted downward because of the down round feature) and will also recognize the effect of the trigger within equity. The provisions of the new ASU related to down rounds are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
Loss Contingencies	Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. See further discussion at Note 13.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 18. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) consists of net income and unrealized gains and losses on securities available for sale and changes in unrealized gains and losses on postretirement liabilities, which are also recognized as separate components of equity, net of tax. In February 2018, the FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. • A description of the accounting policy for releasing income tax effects from AOCI; • Whether they elect to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act; and • Information about the other income tax effects that are reclassified. The amendments affect any organization that is required to apply the provisions of Topic 220, Income Statement—Reporting Comprehensive Income
Off Balance Sheet Financial Instruments	Off Balance Sheet Financial Instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Operating Segments	Operating Segments While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Revenue from Contracts with Customers	In May 2014, FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date In September 2017, the FASB issued ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments.
Recognition and Measurement of Financial Assets and Financial Liabilities	In January 2016, the FASB issued ASU 2016-01 , Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.
Leases	In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842) In January 2018, the FASB issued ASU No. 2018-01, Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842. • Provide an optional transition practical expedient for the adoption of ASU 2016-02 that, if elected, would not require an organization to reconsider their accounting for existing land easements that are not currently accounted for under the old leases standard; and • Clarify that new or modified land easements should be evaluated under ASU 2016-02, once an entity has adopted the new standard. This ASU is effective with ASU 2016-02 for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted. Management is currently evaluating the impact of the adoption of this guidance on the Company’s consolidated financial statements and expects to recognize an increase in other assets and other liabilities for the rights and obligations created by leasing of branch offices. Management also expects minimal impact in the income statement with respect to occupancy expense related to leases.
Measurement of Credit Losses on Financial Instruments	In June 2016, FASB Issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.
Classification of Certain Cash Receipts and Cash Payments	In August 2016, FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments 1. Debt prepayment or debt extinguishment costs. 2. Settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing. 3. Contingent consideration payments made after a business combination. 4. Proceeds from the settlement of insurance claims. 5. Proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies. 6. Distributions received from equity method investees. 7. Beneficial interests in securitization transactions. 8. Separately identifiable cash flows and application of the predominance principle. For public business entities, the guidance in the ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Entities must apply the guidance retrospectively to all periods presented but may apply it prospectively from the earliest date practicable if retrospective application would be impracticable. The adoption of this guidance does not have a material impact on the Company’s consolidated financial statements.
Premium Amortization on Purchased Callable Debt Securities	In March 2017, the FASB issued Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities.

Unaudited First Second Third Fourth 2017: Quarter Quarter Quarter Quarter Total (Dollars in thousands, except per share data) Interest income $ 21,060 $ 23,553 $ 24,048 $ 24,849 $ 93,510 Interest expense 2,584 3,059 3,545 3,969 13,157 Net interest income 18,476 20,494 20,503 20,880 80,353 Provision for loan losses 1,475 842 721 1,215 4,253 Net interest income after provision for loan losses 17,001 19,652 19,782 19,665 76,100 Non-interest income 5,384 7,090 6,305 6,460 25,239 Non-interest expenses 20,290 (1) 15,176 15,464 17,329 (2) 68,259 Income before taxes 2,095 11,566 10,623 8,796 33,080 Income tax expense 557 3,377 3,067 4,294 (3) 11,295 Net income $ 1,538 $ 8,189 $ 7,556 $ 4,502 $ 21,785 Earnings per share: Basic earnings $ 0.03 $ 0.16 $ 0.15 $ 0.09 $ 0.44 Diluted earnings 0.03 0.16 0.15 0.09 0.44 1. Non-interest expense was higher for the first quarter of 2017 as a result of the recognition of $5.0 million associated with the Ohio Legacy acquisition discussed above. 2. During the fourth quarter 2017, the Company recognized a $2.3 million other asset impairment charge. In 2003, Home Savings entered into two development loans on which the borrower subsequently filed bankruptcy, and a Court appointed receiver liquidated the collateral. The proceeds from the sale of the collateral have remained in escrow with the Court since 2007 as a number of competing claims were made against the proceeds. In 2011, a lower court affirmed Home Savings' priority position in the proceeds, and its lien validity was affirmed by the same Court in 2016. However, in December 2017, an Appellate Court ruled that a portion of the proceeds should be awarded to another claimant. The $2.3 million charge reflects the Appellate court ruling. It is the Company’s intent to continue to pursue a full recovery. 3. Includes $1.5 million in additional tax expense due to the remeasurement of net deferred tax assets as part of the Tax Cuts and Job Act. Unaudited First Second Third Fourth 2016: Quarter Quarter Quarter Quarter Total (Dollars in thousands, except per share data) Interest income $ 17,020 $ 17,399 $ 17,815 $ 18,495 $ 70,729 Interest expense 2,147 2,065 2,055 2,161 8,428 Net interest income 14,873 15,334 15,760 16,334 62,301 Provision for loan losses 2,155 395 1,344 1,493 5,387 Net interest income after provision for loan losses 12,718 14,939 14,416 14,841 56,914 Non-interest income 4,658 5,780 6,003 5,635 22,076 Non-interest expenses 12,464 12,860 12,978 13,717 (1) 52,019 Income before taxes 4,912 7,859 7,441 6,759 26,971 Income tax expense (benefit) 1,592 2,529 2,288 1,734 8,143 Net income $ 3,320 $ 5,330 $ 5,153 $ 5,025 $ 18,828 Earnings per share: Basic earnings $ 0.07 $ 0.11 $ 0.11 $ 0.11 $ 0.40 Diluted earnings 0.07 0.11 0.11 0.11 0.40 1.

Compliance With Regulatory Capital Requirements Under Banking Regulations [Line Items]
Capital adequacy requirements		The Basel III Capital Rules establish a common equity Tier 1 minimum capital requirement (4.5% of risk-weighted assets), a minimum Tier 1 capital to risk-based assets requirement (6% of risk-weighted assets) and assigns a risk weight (150%) to exposures that are more than 90 days past due or are on nonaccrual status and to certain commercial real estate facilities that finance the acquisition, development or construction of real property. The rules also require unrealized gains and losses on certain available-for-sale securities holdings to be included for purposes of calculating regulatory capital requirements unless a one-time opt-in or opt-out is exercised. In connection with the adoption of the Basel III Capital Rules, United Community and Home Savings elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1. The rule limits a banking organization’s capital distributions and certain discretionary bonus payments if the banking organization does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital risk-based weighted assets in addition to the amount necessary to meeting its minimum risk-based capital requirements.
