Accounting Policies [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION United Community Financial Corp. (United Community or the Company) was incorporated in the State of Ohio in February 1998 for the purpose of owning all of the outstanding capital stock of Home Savings and Loan Company of Youngstown, Ohio (Home Savings and Loan) issued upon the conversion of Home Savings and Loan from a mutual savings association to a permanent capital stock savings association (Conversion). Upon consummation of the Conversion on July 8, 1998, United Community became the unitary thrift holding company for Home Savings and Loan. Immediately following United Community’s acquisition of Ohio Legacy Corp. (OLCB) on January 31, 2018, Home Savings and Loan was merged into Premier Bank & Trust, OLCB’s wholly-owned, state-chartered bank subsidiary (PB&T), and the surviving bank changed its name to Home Savings Bank. In connection with OLCB acquisition, United Community became a financial holding company, and Home Savings Bank, its wholly-owned bank subsidiary following the merger (Home Savings or the Bank), is now an Ohio bank. Home Savings conducts its business from its main office located in Youngstown, Ohio, 35 retail banking offices, 13 loan production centers and three wealth management offices located throughout Ohio, western Pennsylvania, West Virginia, southeast Michigan, Indiana and Kentucky. 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, HSB Insurance, LLC acquired certain assets of 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, HSB Insurance, LLC acquired certain assets of Stevens Insurance Agency, which offers insurance products for business and residential customers, including auto, commercial, homeowners and life-health. HSB Capital, LLC, a wholly-owned subsidiary of United Community, 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 the 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 similar 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. The accompanying consolidated financial statements of United Community have been prepared in accordance with instructions relating to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles (U.S. GAAP) for complete financial statements. However, such information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair statement of results for the interim periods. The results of operations for the three and six months ended June 30, 2018, are not necessarily indicative of the results to be expected for the year ending December 31, 2018. The consolidated financial statements and notes thereto should be read in conjunction with the audited financial statements and notes contained in United Community’s Form 10-K for the year ended December 31, 2017. The consolidated financial statements include the accounts of United Community and its subsidiaries, Home Savings, HSB Insurance, LLC, HSB Capital, LLC and HSB Insurance, Inc. All material inter-company transactions have been eliminated. Some items in the prior year financial statements were reclassified to conform to the current presentation. These reclassifications had no effect on prior year consolidated statements of operations or shareholders’ equity.

Accounting Changes And Error Corrections [Abstract]
RECENT ACCOUNTING DEVELOPMENTS	2. RECENT ACCOUNTING DEVELOPMENTS On January 1, 2018, the Company adopted Accounting Standars Update (ASU) 2014-09 Revenue from Contracts with Customers The Company adopted ASC 606 using the modified retrospective method applied to all contracts not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606 while prior period amounts continue to be reported in accordance with legacy GAAP. The adoption of ASC 606 did not result in a change to the accounting for any of the in-scope revenue streams; as such, no cumulative effect adjustment was recorded. In January 2016, the FASB issued ASU 2016-01 , Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . In February 2016, the Financial Accounting Standars Board (FASB) issued ASU 2016-02 - Leases (Topic 842) In June 2016, the FASB Issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments • Debt prepayment or debt extinguishment costs. • 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. • Contingent consideration payments made after a business combination. • Proceeds from the settlement of insurance claims. • Proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies. • Distributions received from equity method investees. • Beneficial interests in securitization transactions. • Separately identifiable cash flows and application of the predominance principle. For public business entities, the guidance in ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for all entities. 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 did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . In March 2017, the FASB issued Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . In May 2017, the FASB issued ASU 2017-09 , Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting ( ASU 2017-09) . 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 include guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. 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. 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. In July 2017, the FASB issued ASU 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). 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. ASU 2017-11 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 ASU 2017-11 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. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . In May 2018, the FASB issued ASU 2018-06, Codification Improvements to Topic 942, Financial Services—Depository and Lending Accounting for Net Deferred Tax Charges Financial Services – Depository and Lending – Income Taxes In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting Compensation—Stock Compensation Equity—Equity-Based Payments to Non-Employees. In July, the FASB issued ASU 2018-09, Codification Improvements. ASU 2018-09 affects a wide variety of Topics in the Codification. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in ASU 2018-09 do not require transition guidance and will be effective upon issuance of ASU 2018-09. However, many of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018, for public business entities. The adoption of this guidance is not expected to have an impact of the Company’s consolidated financial statements. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases (ASU 2018-10). affecting narrow aspects of the guidance issued in the amendments in ASU 2016-02.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
STOCK COMPENSATION	3. STOCK 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 (SARs), 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 with respect to awards issued under the 2007 Plan that 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, SARs, or other forms of stock-based incentive awards. Because the 2007 Plan terminated, no additional awards may be made under it. 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 with respect to 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. There were 50,000 stock options granted under the 2015 Plan during the six months ended June 30, 2018 and none granted during the six months ended June 30, 2017. Pursuant to the terms of the 2015 Plan, any options granted must be exercised within 10 years from the date of grant. Expenses related to prior stock option grants are included with salaries and employee benefits. The Company recognized $19,000 and $32,000 in stock option expense for the three and six months ended June 30, 2018, respectively. The Company recognized $0 and $1,000 in stock option expense for the three and six months ended June 30, 2017, respectively. The Company expects to recognize an additional $39,000 in stock option expense for the remainder of 2018. A summary of option activity for the six months ended June 30, 2018 in the 2015 Plan, the 2007 Plan and the 1999 Plan is as follows: For the six months ended June 30, 2018 Weighted Aggregate average intrinsic value Shares exercise price (in thousands) Outstanding at beginning of year 260,533 $ 2.55 Granted 50,000 9.66 Exercised (70,101 ) 3.31 Forfeited and expired — — Outstanding at end of period 240,432 3.81 $ 1,726 Shares subject to options exercisable at end of period 190,432 2.28 $ 1,659 Information related to stock options for the six months ended June 30, 2018 and 2017 follows: June 30, 2018 June 30, 2017 Intrinsic value of options exercised $ 450,486 $ 208,633 Cash received from option exercises 232,000 74,000 Tax benefit realized from option exercises 67,298 73,022 Weighted average fair value of options granted, per share $ 1.54 $ — Information related to stock options granted during the six months ended June 30, 2018 were as follows: Six Months Ended June 30, 2018 Risk-free interest rate 2.69 % Expected term (years) 5 Expected stock volatility 19.68 % Dividend yield 2.48 % As of June 30, 2018, there were 50,000 nonvested stock options outstanding. Outstanding stock options at June 30, 2018 have a weighted average remaining life of 3.93 years and may be exercised in the range of $1.20 to $9.66 per share. Restricted Stock Awards: The 2007 Plan permitted and the 2015 Plan permits the issuance of restricted stock awards to eligible employees and nonemployee directors. Nonvested shares at June 30, 2018 aggregated 223,816, of which 24,908 are expected to vest during the remainder of 2018, 124,237 in 2019, 40,315 in 2020 and 34,356 in 2021. Expense related to restricted stock awards is charged to salaries and employee benefits and is recognized over the vesting period of the awards based on the fair value of the shares at the grant date. The Company recognized approximately $229,000 and $471,000 in restricted stock award expense for the three and six months ended June 30, 2018, respectively. The Company recognized approximately $185,000 and $456,000 in restricted stock award expense for the three and six months ended June 30, 2017, respectively. The Company expects to recognize additional expenses related to restricted stock awards of approximately $410,000 in 2018, $456,000 in 2019, $236,000 in 2020 and $112,000 in 2021. The total average per share fair value of shares vested during the six months ended June 30, 2018 was $9.47. A summary of changes in the Company’s nonvested restricted shares for the six months ended June 30, 2018 is as follows: For the six months ended June 30, 2018 Weighted average grant date Shares fair value Nonvested at beginning of year 277,035 $ 6.73 Granted 57,985 $ 9.75 Vested (110,397 ) $ 6.23 Forfeited (807 ) $ 7.48 Nonvested shares at end of period 223,816 $ 7.75 Annual Incentive Plan The Annual Incentive Plan (AIP) provides incentive compensation awards to certain officers of the Company. Annual incentive awards are generally based upon the actual performance of the Company and individual participant performance for the twelve months ending December 31, compared to the actual performance of a peer group 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 in cash and/or restricted stock. The restricted stock vests equally over three years, beginning on the first anniversary of the date the restricted stock is issued. The Company incurred $95,000 and $190,000 in expense for the restricted stock portion of the AIP for the three and six months ended June 30, 2018 and $426,000 and $871,000 for the cash portion of the AIP for the three and six months ended June 30, 2018. The Company incurred $46,000 and $122,000 in expense for the restricted stock portion of the AIP for the three and six months ended June 30, 2017 and $434,000 and $930,000 for the cash portion of the AIP for the three and six months ended June 30, 2017. Long-term Incentive Plan The Long-term Incentive Plan (LTIP) provides a long-term incentive compensation opportunity to certain executive officers, whose participation and target award opportunities will be approved by the Compensation Committee of the Board of Directors. 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 $212,000 and $381,000 for the LTIP for the three and six months ended June 30, 2018. The Company incurred $(4,000) and $149,000 in expense for the LTIP for the three and six months ended June 30, 2017, respectively.

REVENUE RECOGNITION

REVENUE RECOGNITION	6 Months Ended

Revenue From Contract With Customer [Abstract]
REVENUE RECOGNITION	4. REVENUE RECOGNITION The Company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve this result, the following five steps are applied: Step 1: Identify the contract(s) with the customer Step 2: Identify the performance obligation(s) in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation The new revenue guidance applies to all contracts with customers to provide goods or services in the ordinary course of business, except for loans and securities, which are specifically excluded from the scope. Because loans and securities are outside the scope of the revenue standard, the Company will not use the new standard to account for gains and losses on its investments in securities, loans and derivatives. The Company also will not use the standard to account for interest and dividend income on financial instruments owned or those included in the Company’s lending activities. Home Savings’ servicing of loans sold to investors requires Home Savings to provide specific administrative functions for the owner(s) of these assets. These administrative functions include collecting cash flows from borrowers and remitting them to beneficial interest holders, monitoring delinquencies and executing foreclosures. Servicing rights that relate to transferred financial assets meet the conditions for sale accounting under ASC 860. ASC 860 requires the recognition of a servicing asset or liability when the benefits of servicing obtained from the contract are respectively greater than or less than adequate compensation (as defined in ASC 860) for performing the servicing. While ASC 860 provides initial recognition and subsequent measurement guidance for recognized servicing assets and liabilities, it does not include any explicit guidance for recognizing contractually specified servicing fees when servicing income is equal to adequate compensation. Therefore, income from servicing financial assets in the scope of ASC 860 is not in the scope of ASC 606, regardless of whether a servicing asset or liability exists. This is because ASC 606 contains an exception to its scope for contracts that fall under ASC 860. Deposit-related fees and charges are in the scope of ASC 606, even though ASC 405 is listed as an exception to the scope of the standard. That is because ASC 405, which the Company applies to determine the appropriate liability accounting for customer deposits, does not provide a model for recognizing fees related to customer deposits (e.g., automated teller machine fees, nonsufficient funds fees, account maintenance or dormancy fees). When reviewing standard customer agreements, fees are charged as the service is rendered and therefore there are no changes to recognizing income for deposit-related fees. The Company records real estate owned and other repossessed assets (OREO) at fair value less costs to sell upon foreclosure. The objective is to sell OREO within a short period of time because of regulatory and capital requirements. After foreclosure, these assets are carried at the lower of their carrying amount or their fair value less selling costs, so significant gains and losses are uncommon upon sale. OREO is often sold in a transaction that, under the standard, may not be considered a contract with a customer because the sale of the asset is not an output of the entity’s ordinary activities. However, sales of nonfinancial assets, including in substance nonfinancial assets, should be accounted for using new guidance in ASC 610-20, Other Income — Gains and Losses from the Derecognition of Nonfinancial Assets, which requires entities to apply certain measurement and recognition concepts of ASC 606. Accordingly, the Company recognizes the sale of a real estate property, along with any associated gain or loss, when control of the property transfers to the buyer. For sales of existing real estate properties, this generally will occur at a point in time. Insurance agency income is within the scope of ASC 606. The majority (75%) of the Company’s insurance agency income is derived from direct-bill customers. With this arrangement, the customer is billed directly from the insurance carrier. As a result, the insurance carrier pays a commission to the Company upon completion of the required documentation (policy application or renewal) and recognizes income at that time. Due to the nature and timing of receipt of these commissions, there will be no change in the manner in which income is recognized. Agency-billed customers account for approximately 25% of the overall insurance agency income. Premiums are collected from customers and remitted to the insurance carrier, net of commission, within a short period of time. At the time the premiums are remitted to the insurance carrier, all work is completed and revenue recognized at that time. Due to the nature and timing of when the premiums are recognized, there will be no change to the timing of the recognition of insurance agency income. Debit card fee income is earned as a result of standard interchange fees contractually obligated by Visa to be paid. Fees are paid when they are essentially earned, which include fees charged to a merchant for the presentment of credit/debit card transactions (interchange). The service is considered complete upon fulfillment of the transaction when the interchange fee is earned and paid. Credit card fees are paid when earned as a result of an agreement between the bank and a third party provider. AS a result, there is no change to the timing of recognition of this income. Trust fee income is calculated based on assets under management. Fees are recognized at the end of the month to which the service has been provided for customers billed monthly. This amounts of approximately 85% of trust fee income recognized, which is collected within a short period of time after the fee is assessed to the customer. Quarterly and annual fees are accrued and collected based on the contractual agreements with customers. Fees are assessed to these customers and paid at the end of each quarter. Due to the nature and timing of when monthly fees are assessed, there will be no change to the way those fees are currently recognized. Quarterly and annual fees will continue to be recognized over the period when the fees are earned, regardless of when they are assessed to the customer. Brokerage revenue is recognized each month as sales occur. Brokerage revenue is paid from sales to customers by a third-party. In a manner similar to that of insurance agency revenue, income is paid directly to the Bank by the third-party once the sale to the customer is complete. Due to the nature and timing of when the income is earned, there will be no change to timing of when this income is recognized.

Unrealized losses on these securities have not been recognized into income during the three and six months ended June 30, 2018 and 2017 because the issuer’s securities are of high credit quality (rated AA or higher), 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. There is risk that longer term rates could rise further resulting in greater unrealized losses. The Company expects to realize all interest and principal on these securities and has no intent to sell, and more than likely will not be required to sell, these securities before their anticipated recovery. All of the obligations of U.S. states and political subdivisions held for sale that were temporarily impaired at June 30, 2018 and December 31, 2017, were impaired due to the level of interest rates at the time of purchase compared to current interest rates. Unrealized losses on these securities have not been recognized into income for the three and six months ended June 30, 2018 or 2017 because the issuer’s securities are of high credit quality (rated AA or higher), it is likely that management will not be required to sell, and has no intent 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.

The net unrealizable 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. Because of this transfer, the total losses less than 12 months and greater than 12 months reported in the table above 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. All of the mortgage-backed securities held to maturity that were temporarily impaired at June 30, 2018 and December 31, 2017, were impaired due to the level of interest rates at the time of purchase compared to current interest rates.

Proceeds from the sale of available for sale securities were $5.7 million and $48.1 million, for the three months ended June 30, 2018 and 2017, respectively. Gross gains of $94,000 and $345,000 were realized on these sales during the three months ended June 30, 2018 and 2017, respectively. Gross losses of $0 and $44,000 were realized on these sales during these same periods. Proceeds from the sale of available for sale securities were $10.4 million and $53.2 million, for the six months ended June 30, 2018 and 2017, respectively. Gross gains of $233,000 and $374,000 were realized on these sales during the six months ended June 30, 2018 and 2017, respectively.

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. In determining the qualitative factors, 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. As of June 30, 2018, the Company evaluated 24 quarters of net charge-off history and applied this information to the current period. This component is combined with the qualitative component to arrive at the loss factor, which is applied to the outstanding balance of homogenous loans.

A troubled debt restructuring is considered to be in payment default once it is 30 days contractually past due under the modified terms. 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. 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, certain 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. 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 June 30, 2018 and December 31, 2017, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows: June 30, 2018 (Dollars in thousands) Unclassified Classified Unclassified Special Mention Substandard Doubtful Loss Total Classified Total Loans Commercial Loans Multifamily $ 138,238 $ 2,491 $ 275 $ — $ — $ 275 $ 141,004 Nonresidential 379,794 5,162 11,668 — — 11,668 396,624 Land 16,887 — — — — — 16,887 Construction 119,065 8,626 — — — — 127,691 Secured 186,069 4,851 21,253 — — 21,253 212,173 Unsecured 6,345 — 93 — — 93 6,438 Total commercial loans 846,398 21,130 33,289 — — 33,289 900,817 Residential mortgage loans One-to four-family 880,779 1,102 6,702 — — 6,702 888,583 Construction 40,623 — — — — — 40,623 Total residential mortgage loans 921,402 1,102 6,702 — — 6,702 929,206 Consumer Loans Home equity 186,276 — 1,495 — — 1,495 187,771 Auto 83,766 — 63 — — 63 83,829 Marine 1,223 — 181 — — 181 1,404 Recreational vehicle 4,817 — 62 — — 62 4,879 Other 7,025 — 1 — — 1 7,026 Total consumer loans 283,107 — 1,802 — — 1,802 284,909 Total loans $ 2,050,907 $ 22,232 $ 41,793 $ — $ — $ 41,793 $ 2,114,932 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 Purchased Credit Impaired Loans: The Company has purchased loans for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	9. FAIR VALUE MEASUREMENT 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. In addition to the Special Assets Department review, a third party independent review is also performed. 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, 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 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 on or 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 (Level 2). The fair value of the Company’s permanent construction loans held for sale is determined using the current 60 day forward contract price for 30 year conventional loans 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). 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).

This resulted in an increase of the provision for loan losses of $105,000 and $147,000 during the three and six months ended June 30, 2018, respectively. 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 $1.4 million at June 30, 2017, which includes a specific valuation allowance of $5,000. This resulted in an increase in the provision for loan losses of $252,000 and $479,000 for the three and six months ended June 30, 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 $1.7 million at December 31, 2017, that includes a specific valuation allowance of $491,000. 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 values versus appraised value. During the reported periods, discounts applied to appraisals for estimated selling costs were 10%. At June 30, 2018, $240,000 in mortgage servicing rights were carried at fair value, resulting in a net valuation allowance of $20,000. At June 30, 2017, mortgage servicing rights carried at fair value totaled $87,000, resulting in a net valuation allowance of $5,000. Mortgage servicing rights are valued by an independent third party that is active in purchasing and selling these instruments. A net impairment reflected in other income totaled $20,000 and $11,000 for the three and six months ended June 30, 2018, respectively. Net impairment reflected in other income totaled $2,000 and $5,000 for the three and six months ended June 30, 2017. The value reflects the characteristics of the underlying loans.

(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 Beginning January 1, 2018, fair values of loans, excluding loans held for sale, are estimated based on the price received to sell the asset (exit price), considering the lifetime credit risk of the loan portfolio. For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based the weighted average next repricing date and weighted average index, resulting in a Level 3 classification. Fair values for other loans are estimated using the weighted average months to maturity and weighted average contractual interest rate, using weightings based on principal balances, 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 represent an exit price. At December 31, 2017, fair values of loans, excluding loans held for sale, were estimated as follows: For variable rate, loans that reprice frequently and with no significant change in credit risk, fair values were based on carrying values resulting in a Level 3 classification. Fair values for other loans were estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similarly credit quality resulting in a Level 3 classification. Impaired loans were valued at the lower of cost or fair value. The methods utilized at December 31, 2017 to estimate fair value did 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) Other Borrowings Short-term borrowings, generally, maturing within 90 days, approximate their fair values resulting in a Level 2 classification. 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. (g) 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. (h) 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.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	11. EARNINGS PER SHARE The Company has granted stock compensation awards with nonforfeitable dividend rights which are considered participating securities. As such, earnings per share is computed using the two-class method as required by ASC 206-10-45. Basic earnings per common share is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding during the period which, excludes the participating securities. Diluted earnings per common share includes the dilutive effect of additional potential common shares from stock compensation awards, but also excludes awards considered participating securities. There were 50,000 stock options that were anti-dilutive for the three and six months ended June 30, 2018 and no stock options were anti-dilutive for the three and six months ended June 30, 2017.

OTHER COMPREHENSIVE INCOME (LOSS)	12. OTHER COMPREHENSIVE INCOME (LOSS) Other comprehensive income (loss) included in the consolidated statements of shareholders’ equity consists of unrealized gains and losses on available for sale securities, accretion of unrealized losses on held to maturity securities and disproportionate tax effects. The change includes reclassification of net gains or (losses) on sales of securities of $94,000 and $301,000 for the three months ended June 30, 2018 and 2017, respectively, and $233,000 and $330,000 for the six months ended June 30, 2018 and 2017, respectively. Reclassifications also includes accretion of unrealized losses on held to maturity securities. Other comprehensive income (loss) components and related tax effects for the three-month periods are as follows: Unrealized Gains (Losses) on Securities Available Sale Disproportionate Tax Effect from Securities Available for Sale Losses on Securities Transferred From Available for Sale to Held to Maturity Total June 30, 2018 (Dollars in thousands) Balances at beginning of period, net of tax $ (4,924 ) $ (17,110 ) $ (641 ) $ (22,675 ) Other comprehensive loss before reclassifications (1,359 ) — — (1,359 ) Accretion of unrealized losses of securities transferred from available for sale to held to maturity recognized in other comprehensive income — — 31 31 Reclassification adjustment for gains realized in income (74 ) — — (74 ) Net current period other comprehensive income (1,433 ) — 31 (1,402 ) Balances at end of period, net of tax $ (6,357 ) $ (17,110 ) $ (610 ) $ (24,077 ) Unrealized Gains (Losses) on Securities Available for Sale Disproportionate Tax Effect from Securities Available for Sale Losses on Securities Transferred From Available for Sale to Held to Maturity Total June 30, 2017 (Dollars in thousands) Balances at beginning of period, net of tax $ (2,165 ) $ (17,110 ) $ (767 ) $ (20,042 ) Other comprehensive income before reclassifications 1,758 — — 1,758 Accretion of unrealized losses of securities transferred from available for sale to held to maturity recognized in other comprehensive income — — 32 32 Reclassification adjustment for gains realized in income (196 ) — — (196 ) Net current period other comprehensive income 1,562 — 32 1,594 Balances at end of period, net of tax $ (603 ) $ (17,110 ) $ (735 ) $ (18,448 ) Other comprehensive income (loss) components and related tax effects for the six-month periods are as follows: Unrealized Gains (Losses) on Securities Available Sale Disproportionate Tax Effect from Securities Available for Sale Losses on Securities Transferred From Available for Sale to Held to Maturity Total June 30, 2018 (Dollars in thousands) Balances at beginning of period, net of tax $ (904 ) $ (17,110 ) $ (671 ) $ (18,685 ) Other comprehensive loss before reclassifications (5,269 ) — — (5,269 ) Accretion of unrealized losses of securities transferred from available for sale to held to maturity recognized in other comprehensive income — — 61 61 Reclassification adjustment for gains realized in income (184 ) — — (184 ) Net current period other comprehensive income (5,453 ) — 61 (5,392 ) Balances at end of period, net of tax $ (6,357 ) $ (17,110 ) $ (610 ) $ (24,077 ) Unrealized Gains (Losses) on Securities Available for Sale Disproportionate Tax Effect from Securities Available for Sale Losses on Securities Transferred From Available for Sale to Held to Maturity Total June 30, 2017 (Dollars in thousands) Balances at beginning of period, net of tax $ (3,130 ) $ (17,110 ) $ (800 ) $ (21,040 ) Other comprehensive income before reclassifications 2,742 — 2,742 Accretion of unrealized losses of securities transferred from available for sale to held to maturity recognized in other comprehensive income — — 65 65 Reclassification adjustment for gains realized in income (215 ) — — (215 ) Net current period other comprehensive income 2,527 — 65 2,592 Balances at end of period, net of tax $ (603 ) $ (17,110 ) $ (735 ) $ (18,448 ) 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.

REGULATORY CAPITAL REQUIREMENTS

Banking And Thrift [Abstract]
REGULATORY CAPITAL REQUIREMENTS	13. REGULATORY CAPITAL REQUIREMENTS 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 will be phased in through January 1, 2019, when the full capital conservation buffer requirement will be effective. The capital conservation buffer for 2018 is 1.875%. The capital conservation buffer for 2017 was 1.25%. 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.

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 include guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. 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. The amendments should be applied prospectively to an award modified on or after the adoption date.

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. ASU 2017-11 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 ASU 2017-11 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.

Some of the amendments in ASU 2018-09 do not require transition guidance and will be effective upon issuance of ASU 2018-09. However, many of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018, for public business entities.

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.
