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 or the Bank) issued upon the conversion of Home Savings 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. 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 and West Virginia. 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, 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 repaid from the cash flow from the operations of the business. On January 31, 2017, United Community completed its acquisition of Ohio Legacy Corp. (OLCB). Immediately following the acquisition of OLCB, Home Savings was merged into Premier Bank & Trust, OLCB’s wholly-owned subsidiary state chartered bank (PB&T), and PB&T changed its name to Home Savings Bank. As a result of the acquisition, United Community issued 3,033,604 United Community common shares and paid $20.4 million to OLCB shareholders. Also, in connection with the acquisition, United Community became a financial holding company, and its wholly owned subsidiary is now an Ohio bank. 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 nine months ended September 30, 2017, are not necessarily indicative of the results to be expected for the year ending December 31, 2017. 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, 2016. 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.

In August 2016, 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 the ASU 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. Management is currently evaluating the impact of the adoption of this guidance 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 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 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 for. The amendments should be applied prospectively to an award modified on or after the adoption date. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements. 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.

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, 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, stock appreciation rights (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 no stock options granted in the three and nine months ended September 30, 2017 and 2016. 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 $0 and $1,000 in stock option expense for the three and nine months ended September 30, 2017, respectively. The Company recognized $2,000 and $8,000 in stock option expense for the three and nine months ended September 30, 2016, respectively. The Company does not expect to recognize any stock option expense for the remainder of 2017. A summary of option activity in the plans is as follows: For the nine months ended September 30, 2017 Weighted Aggregate average intrinsic value Shares exercise price (in thousands) Outstanding at beginning of year 371,218 $ 2.55 Granted — — Exercised (80,085 ) 2.69 Forfeited and expired (600 ) 2.10 Outstanding at end of period 290,533 2.51 $ 2,061 Shares subject to options exercisable at end of period 290,533 2.51 $ 2,061 Information related to stock options for the nine months ended September 30, 2017 and 2016 follows: September 30, 2017 September 30, 2016 Intrinsic value of options exercised $ 487,000 $ 631,000 Cash received from option exercises 216,000 462,000 Tax benefit realized from option exercises 170,523 — Weighted average fair value of options granted, per share $ — $ — As of September 30, 2017, there were no unvested stock options remaining. Outstanding stock options at September 30, 2017 have a weighted average remaining life of 2.79 years and may be exercised in the range of $1.20 to $5.89 per share. Restricted Stock Awards: The 2007 Plan permitted and the 2015 Plan permits the issuance of restricted stock awards to employees and nonemployee directors. Nonvested shares at September 30, 2017 aggregated 275,438, of which 7,709 are expected to vest during the remainder of 2017, 129,044 in 2018, 106,012 in 2019 and 32,673 in 2020. 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 $240,000 and $696,000 in restricted stock award expenses for the three and nine months ended September 30, 2017. The Company recognized approximately $254,000 and $716,000 in restricted stock award expense for the three and nine months ended September 30, 2016. The Company expects to recognize additional expenses of approximately $203,000 in 2017, $581,000 in 2018, $259,000 in 2019 and $60,000 in 2020. The total average per share fair value of shares vested during the nine months ended September 30, 2017 was $8.52. A summary of changes in the Company’s nonvested restricted shares for the nine months ended September 30, 2017 is as follows: For the nine months ended September 30, 2017 Weighted average grant date Shares fair value Nonvested at beginning of year 341,184 $ 5.50 Granted 75,875 $ 8.60 Vested (141,621 ) $ 4.98 Forfeited — $ — Nonvested shares at end of period 275,438 $ 6.63 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 $100,000 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 $146,000

Business Combinations [Abstract]
BUSINESS COMBINATION	4. 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 (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 subsidiary of OLCB, and changed its name to Home Savings Bank. As a result of the acquisiton and in accordance with the terms of the Merger Agreement, each preferred share 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 were exchanged for 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 acquisition. Acquisition related costs aggregating $5.0 million were included in United Community’s Consolidated Statements of Operations for the nine months ended September 30, 2017. The fair value of the common shares issued as part of the consideration paid for OLCB was determined in the basis of the closing price of United Community’s commons shares on the acquisition 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 acquisition 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 7,988 Total assets acquired $ 330,906 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 $ 18,420 The fair value of net assets acquired included fair value adjustments to certain receivables that were not considered impaired as of the acquisition 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 acquisition 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 acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected with a fair value and gross contractual amounts receivable of $2.5 million and $2.6 million, respectively, on the date of acquisition. Upon adoption of ASU 2016-16, Business Combinations (Topic 805) The following table presents proforma information as if the OLCB acquisition 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 $4.1 million in acquisition related expenses incurred by United Community and $368,000 in acquisition related expenses for OLCB during the nine months ended September 30, 2017. The impact of the acquired insurance agencies is considered immaterial and not included in the table below. For the Nine Months Ended September 30, 2017 2016 (In thousands, except per share data) Net interest income $ 61,185 $ 55,595 Net income 16,928 16,118 Basic earnings per share $ 0.34 $ 0.32 Diluted earnings per share $ 0.34 $ 0.32 Goodwill is recorded arising from the acquisition, 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 acquisition benefits the Company and its shareholders by enabling the Company to further expand into the markets currently served by OLCB and strengthening the competitive position of the combined organization. Furthermore, the Company believes its increased asset size after the acquisition 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. The fair value of $2.2 million of intangible assets related to core deposits is subject to change pending receipt of the final valuation. 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 during the nine months ended September 30, 2017 or 2016 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 September 30, 2017 and December 31, 2016, 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 nine months ended September 30, 2017 or 2016 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 September 30, 2017 and December 31, 2016, 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 nine months ended September 30, 2017 or 2016 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.

Unrealized losses on these securities have not been recognized into income for the nine months ended September 30, 2017 or 2016 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. Proceeds from the sale of available for sale securities were $9.7 million and $5.2 million, for the three months ended September 30, 2017 and 2016, respectively. Gross gains of $236,000 and $218,000 were realized on these sales during the three months ended September 30, 2017 and 2016, respectively. No gross losses were realized on these sales during the three months ended September 30, 2017 or 2016. Income tax expense related to net realized gains and losses was $83,000 and $76,000 for the three months ended September 30, 2017 and 2016, 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 September 30, 2017, the Company evaluated 21 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 September 30, 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: Loans September 30, 2017 (Dollars in thousands) Unclassified Classified Unclassified Special Mention Substandard Doubtful Loss Total Classified Total Loans Commercial Loans Multifamily $ 124,441 $ 1,975 $ 561 $ — $ — $ 561 $ 126,977 Nonresidential 355,846 3,171 7,730 — — 7,730 366,747 Land 13,657 — 9 — — 9 13,666 Construction 107,702 403 — — — — 108,105 Secured 137,977 1,421 28,035 — — 28,035 167,433 Unsecured 8,054 — 94 — — 94 8,148 Total commercial loans 747,677 6,970 36,429 — — 36,429 791,076 Residential mortgage loans One-to four-family 842,928 769 8,166 — — 8,166 851,863 Construction 57,081 — — — — — 57,081 Total residential mortgage loans 900,009 769 8,166 — — 8,166 908,944 Consumer Loans Home equity 191,689 — 1,713 — — 1,713 193,402 Auto 56,845 — 38 — — 38 56,883 Marine 1,395 — 169 — — 169 1,564 Recreational vehicle 5,840 — 409 — — 409 6,249 Other 5,592 — 2 — — 2 5,594 Total consumer loans 261,361 — 2,331 — — 2,331 263,692 Total loans $ 1,909,047 $ 7,739 $ 46,926 $ — $ — $ 46,926 $ 1,963,712 Loans 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 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	9 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). Interest rate caps: Home Savings uses an independent third party that performs a market valuation analysis for interest rate caps. The methodology used consists of a discounted cash flow model, all future floating cash flows are projected and both floating and fixed cash flows are discounted to the valuation date. The yield curve utilized for discounting and projecting is 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 are 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).

This resulted in an increase of the provision for loan losses of $92,000 and $571,000 during the three and nine months ended September 30, 2017, 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 $7.7 million at September 30, 2016, which includes a specific valuation allowance of $989,000. This resulted in an increase in the provision for loan losses of $134,000 and $3.7 million for the three and nine months ended September 30, 2016. 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. 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 September 30, 2017, mortgage servicing rights carried at fair value were $125,000, with a net valuation allowance of $15,000. At September 30, 2016, mortgage servicing rights, carried at fair value totaled $3.3 million, resulting in a net valuation allowance of $741,000. Mortgage servicing rights are valued by an independent third party that is active in purchasing and selling these instruments. Net impairment reflected in other income totaled $10,000 and $15,000 for the three and nine months ended September 30, 2017, respectively. Net (recovery) impairment reflected in other income totaled $(25,000) and $702,000 for the three and nine months ended September 30, 2016. The value reflects the characteristics of the underlying loans. At September 30, 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 $580,000, with a valuation allowance of $423,000. This resulted in expense of $53,000 and $15,000 during the three and nine months ended September 30, 2017. At September 30, 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 an expense (recovery) of $1,000 and $(25,000) during the three and nine months ended September 30, 2016, respectively. At December 31, 2016, other real estate owned had a net carrying amount of $1.0 million, with a valuation allowance of $1.0 million.

The Company has elected the fair value option for newly originated residential mortgage and permanent construction loans held for sale. These loans are intended for sale and the Company believes that 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 or more days past due nor on nonaccrual status as of September 30, 2017 and December 31, 2016.

(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; and 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) 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. No stock options were anti-dilutive for the three and nine months ended September 30, 2017. No stock options were anti-dilutive for the three months and nine months ended September 30, 2016.

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, disproportional tax effects and changes in unrealized gains and losses on the postretirement liability. The change includes reclassification of net gains or (losses) on sales of securities of $236,000 and $218,000 for the three months ended September 30, 2017 and 2016, respectively and $566,000 and $604,000 for the nine months ended September 30, 2017 and 2016, respectively. Reclassifications also include amortization of unrealized gains on postretirement plan and accretion of unrealized loss 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 September 30, 2017 (Dollars in thousands) Balances at beginning of period, net of tax $ (603 ) $ (17,110 ) $ (735 ) $ (18,448 ) Other comprehensive income before reclassifications 639 — — 639 Accretion of unrealized losses of securities transferred from available for sale to held to maturity recognized in other comprehensive income — — 33 33 Reclassification adjustment for gains realized in income (153 ) — — (153 ) Net current period other comprehensive income 486 — 33 519 Balances at end of period, net of tax $ (117 ) $ (17,110 ) $ (702 ) $ (17,929 ) 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 Unrealized Gains (Losses) from Postretirement Plan Disproportionate Tax Effect from Postretirement Plan Total September 30, 2016 (Dollars in thousands) Balances at beginning of period, net of tax $ 8,379 $ (17,110 ) $ (889 ) $ 469 $ 511 $ (8,640 ) Other comprehensive income before reclassifications (1,227 ) — — — — (1,227 ) Amortization of unrealized gains of postretirement plan recognized in other comprehensive income — — — (289 ) — (289 ) Accretion of unrealized losses of securities transferred from available for sale to held to maturity recognized in other comprehensive income — — 47 — — 47 Reclassification adjustment for gains realized in income (142 ) — — — — (142 ) Net current period other comprehensive income (1,369 ) — 47 (289 ) — (1,611 ) Balances at end of period, net of tax $ 7,010 $ (17,110 ) $ (842 ) $ 180 $ 511 $ (10,251 ) Other comprehensive income (loss) components and related tax effects for the nine-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 September 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 3,381 — — 3,381 Accretion of unrealized losses of securities transferred from available for sale to held to maturity recognized in other comprehensive income — — 98 98 Reclassification adjustment for gains realized in income (368 ) — — (368 ) Net current period other comprehensive income 3,013 — 98 3,111 Balances at end of period, net of tax $ (117 ) $ (17,110 ) $ (702 ) $ (17,929 ) 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 Unrealized Gains (Losses) from Postretirement Plan Disproportionate Tax Effect from Postretirement Plan Total September 30, 2016 (Dollars in thousands) Balances at beginning of period, net of tax $ (2,492 ) $ (17,110 ) $ (960 ) $ 831 $ 511 $ (19,220 ) Other comprehensive income before reclassifications 9,895 — — — 9,895 Amortization of unrealized gains of postretirement plan recognized in other comprehensive income — — — (651 ) — (651 ) Accretion of unrealized losses of securities transferred from available for sale to held to maturity recognized in other comprehensive income — — 118 — — 118 Reclassification adjustment for gains realized in income (393 ) — — — — (393 ) Net current period other comprehensive income 9,502 — 118 (651 ) — 8,969 Balances at end of period, net of tax $ 7,010 $ (17,110 ) $ (842 ) $ 180 $ 511 $ (10,251 ) 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

REGULATORY CAPITAL REQUIREMENTS	9 Months Ended

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 2017 is 1.25%. The capital conservation buffer for 2016 was 0.625%. 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.

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 qualitative 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 units with a carrying amount of zero or less than zero at September 30, 2017 or December 31, 2016.

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 for. 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. 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.

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.
