Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION We are a financial holding company headquartered in Moorefield, West Virginia. We operate in three business segments: community banking, trust and wealth management services and insurance services. Our primary business is community banking. Our community bank subsidiary, Summit Community Bank (“Summit Community”) provides commercial and retail banking services primarily in the Eastern Panhandle and Southern regions of West Virginia and the Northern, Shenandoah Valley and Southwestern regions of Virginia. We also operate Summit Insurance Services, LLC in Moorefield, West Virginia and Leesburg, Virginia. Our accounting and reporting policies conform to accounting principles generally accepted in the United States of America and to general practices within the banking industry. Use of estimates : We must make estimates and assumptions that affect the reported amounts and disclosures in preparing our financial statements in conformity with accounting principles generally accepted in the United States of America. Actual results could differ significantly from those estimates. Principles of consolidation : The accompanying consolidated financial statements include the accounts of Summit and its wholly-owned subsidiaries. All significant accounts and transactions among these entities have been eliminated. Comprehensive income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, cash flow hedges and other post-retirement benefits, which are recognized as separate components of equity. Cash and cash equivalents: Cash and cash equivalents includes cash on hand, amounts due from banks (including cash items in process of clearing), interest bearing deposits with other banks and federal funds sold. Loans held for sale : Loans held for sale are valued at the lower of aggregate carrying cost or fair value. Gains or losses realized on the sales of loans are recognized in other income at the time of sale. Cash surrender value of life insurance policies: We have purchased life insurance policies on certain employees. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Presentation of cash flows : For purposes of reporting, cash flows from demand deposits, NOW accounts, savings accounts and short-term borrowings are reported on a net basis, since their original maturities are less than three months. Cash flows from loans and certificates of deposit and other time deposits are reported net. Advertising: Advertising costs are expensed as incurred. Trust services : Assets held in an agency or fiduciary capacity are not our assets and are not included in the accompanying consolidated balance sheets. Trust services income is recognized on the cash basis in accordance with customary banking practice. Reporting such income on a cash basis does not produce results that are materially different from those that would result from use of the accrual basis. Unconsolidated subsidiary trusts: In accordance with accounting principles generally accepted in the United States, we do not consolidate subsidiary trusts which issue guaranteed preferred beneficial interests in subordinated debentures (Trust Preferred Securities). The Trust Preferred Securities qualify as Tier 1 capital for regulatory purposes. See Note 13 of our Notes to Consolidated Financial Statements for a discussion of our subordinated debentures owed to unconsolidated subsidiary trusts.

Significant New Authoritative A

Significant New Authoritative Accounting Guidance	12 Months Ended
	Dec. 31, 2018
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Significant New Authoritative Accounting Guidance	SIGNIFICANT NEW AUTHORITATIVE ACCOUNTING GUIDANCE Recently Adopted We adopted ASU 2014-09, Revenue from Contracts with Customers: Topic 606, and its related amendments on its required effective date of January 1, 2018 utilizing the modified retrospective approach. Since there was no net income impact upon adoption of the new guidance, a cumulative effect adjustment to opening retained earnings was not deemed necessary. We concluded that ASU 2014-09 did not materially change the method in which we currently recognize revenue for these revenue streams. We also completed our evaluation of certain costs related to these revenue streams to determine whether such costs should be presented as expenses or contra-revenue (i.e., gross vs. net). Based on our evaluation, we determined that any classification changes were immaterial to both revenue and expense. ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , among other things, (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet, (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements and (viii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale. ASU 2016-01 was effective for us on January 1, 2018 and did not have a significant impact on our financial statements. In accordance with (iv) above, we measure the fair value of our loan portfolio using exit price notion (see Note 4. Fair Value Measurements). In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The FASB made subsequent amendments to Topic 842 in July 2018 through ASU 2018-10 Codification Improvements to Topic 842, Leases. and ASU 2018-11 Leases (Topic 842): Targeted Improvements. Among these amendments is the provision in ASU 2018-11 that provides entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard will continue to be in accordance with current GAAP (Topic 840, Leases ). The adoption of this standard on January 1, 2019 did not have a material effect on our consolidated financial statements. Our current minimum commitments under long-term operating leases are disclosed in Note 17, Commitments and Contingencies. Pending Adoption During June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments . The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The amendments in this ASU are effective for SEC filers for fiscal years and interim periods within those fiscal years, beginning after December 15, 2019. Accordingly, we will adopt the guidance in the first quarter of 2020 with a cumulative-effect adjustment to retained earnings as of the beginning of the period. In this regard, we appointed a cross-functional implementation team comprised of personnel from risk management, operations and information technology, loan administration and finance and have engaged a third-party to assist us. The team has completed its preliminary implementation process and will test the model we developed to implement the standard using contemporaneous loan data throughout 2019. We continue to evaluate the impact the new standard will have on our consolidated financial statements as the final impact will be dependent upon, among other items, the loan portfolio composition and credit quality at the adoption date, as well as economic conditions, financial models used and forecasts at that time. In March of 2017, the FASB issued ASU No. 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities . This guidance shortens the amortization period for premiums on certain callable debt securities to the earliest call date (with an explicit, noncontingent call feature that is callable at a fixed price and on a preset date), rather than contractual maturity date as currently required under GAAP. The ASU does not impact instruments without preset call dates such as mortgage-backed securities. For instruments with contingent call features, once the contingency is resolved and the security is callable at a fixed price and preset date, the security is within the scope of the ASU. ASU 2017-08 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, and early adoption is permitted. The adoption of the new pronouncement will not have a significant impact on our consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities which will make more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. It is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. We do not expect it to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement . The amendments modify the disclosure requirements in Topic 820 to add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements and the narrative description of measurement uncertainty. Certain disclosure requirements in Topic 820 are also removed or modified. The amendments are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Certain of the amendments are to be applied prospectively while others are to be applied retrospectively. Early adoption is permitted. We do not expect the adoption of ASU 2018-13 to have a material impact on our consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is based upon the exchange price that would be received for an asset or paid to transfer a liability (an 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. A fair value hierarchy is utilized to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs used to measure fair value are as follows: Level 1 : Quoted prices (unadjusted) or 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 and other inputs that are observable or can be corroborated by observable market data. Level 3 : Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Accordingly, securities available-for-sale and derivative financial instruments are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record other assets at fair value on a nonrecurring basis, such as loans held for sale, property held for sale and impaired loans held for investment. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. Following is a description of valuation methodologies used for assets and liabilities recorded at fair value. Available-for-Sale Debt Securities : Debt securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Certain trust preferred securities classified as corporate debt securities are Level 3 due to limited market trades of these classes of securities. Derivative Financial Instruments : Derivative financial instruments are recorded at fair value on a recurring basis. Fair value measurement is based on pricing models run by a third-party, utilizing observable market-based inputs. All future floating cash flows are projected and both floating and fixed cash flows are discounted to the valuation date. As a result, we classify interest rate swaps as Level 2. Loans Held for Sale : Loans held for sale are carried at the lower of cost or fair value. The fair value of loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, we classify loans subject to nonrecurring fair value adjustments as Level 2. Loans : We do not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allowance for loan loss is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the original contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management measures impairment using one of several methods, including collateral value, liquidation value and discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the discounted cash flows or collateral value exceeds the recorded investments in such loans. These loans are carried at recorded loan investment and therefore are not included in the following tables of loans measured at fair value. Impaired loans internally graded as substandard, doubtful, or loss are evaluated using the fair value of collateral method. All other impaired loans are measured for impairment using the discounted cash flows method. Impaired loans where an allowance is established based on the fair value of collateral are included in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, we record the impaired loan as nonrecurring Level 2. When a current appraised value is not available and there is no observable market price, we record the impaired loan as nonrecurring Level 3. When impaired loans are deemed required to be included in the fair value hierarchy, management immediately begins the process of evaluating the estimated fair value of the underlying collateral to determine if a related specific allowance for loan losses or charge-off is necessary. Current appraisals are ordered once a loan is deemed impaired if the existing appraisal is more than twelve months old, or more frequently if there is known deterioration in value. For recently identified impaired loans, a current appraisal may not be available at the financial statement date. Until the current appraisal is obtained, the original appraised value is discounted, as appropriate, to compensate for the estimated depreciation in the value of the loan’s underlying collateral since the date of the original appraisal. Such discounts are generally estimated based upon management’s knowledge of sales of similar collateral within the applicable market area and its knowledge of other real estate market-related data as well as general economic trends. When a new appraisal is received (which is generally within 3 months of a loan being identified as impaired), management then re-evaluates the fair value of the collateral and adjusts any specific allocated allowance for loan losses, as appropriate. In addition, management also assigns a discount of 7–10% for the estimated costs to sell the collateral. Property Held for Sale: Property held for sale consists of real estate acquired in foreclosure or other settlement of loans. Foreclosed assets are initially recorded at fair value, less estimated selling costs, when acquired establishing a new cost basis. Such assets are carried on the balance sheet at the lower of the investment in the real estate or its fair value less estimated selling costs. The fair value of foreclosed properties is determined on a nonrecurring basis generally utilizing current appraisals performed by an independent, licensed appraiser applying an income or market value approach using observable market data (Level 2). Updated appraisals of foreclosed properties are generally obtained if the existing appraisal is more than 18 months old or more frequently if there is a known deterioration in value. However, if a current appraisal is not available, the original appraised value is discounted, as appropriate, to compensate for the estimated depreciation in the value of the real estate since the date of its original appraisal. Such discounts are generally estimated based upon management’s knowledge of sales of similar property within the applicable market area and its knowledge of other real estate market-related data as well as general economic trends (Level 3). Upon foreclosure, any fair value adjustment is charged against the allowance for loan losses. Subsequent fair value adjustments are recorded in the period incurred and included in other noninterest expense in the consolidated statements of income.

Debt Securities, Available-for-sale [Abstract]
Securities	DEBT SECURITIES We classify debt securities as “held to maturity”, “available for sale” or “trading” according to management’s intent. The appropriate classification is determined at the time of purchase of each security and re-evaluated at each reporting date. Securities held to maturity: Certain debt securities for which we have the positive intent and ability to hold to maturity are reported at cost, adjusted for amortization of premiums and accretion of discounts. There are no securities classified as held to maturity in the accompanying financial statements. Securities available for sale: Securities not classified as "held to maturity" or as "trading" are classified as "available for sale." Securities classified as "available for sale" are those securities that we intend to hold for an indefinite period of time, but not necessarily to maturity. "Available for sale" securities are reported at estimated fair value net of unrealized gains or losses, which are adjusted for applicable income taxes and reported as a separate component of shareholders' equity. Trading securities: There are no securities classified as "trading" in the accompanying financial statements. Impairment assessment: Impairment exists when the fair value of a security is less than its cost. Cost includes adjustments made to the cost basis of a security for accretion, amortization and previous other-than-temporary impairments. We perform a quarterly assessment of the debt securities in our investment portfolio that have an unrealized loss to determine whether the decline in the fair value of these securities below their cost is other-than-temporary. This determination requires significant judgment. Impairment is considered other-than-temporary when it becomes probable that we will be unable to recover the cost of an investment. This assessment takes into consideration factors such as the length of time and the extent to which the market values have been less than cost, the financial condition and near term prospects of the issuer including events specific to the issuer or industry, defaults or deferrals of scheduled interest, principal or dividend payments, external credit ratings and recent downgrades and our intent and ability to hold the security for a period of time sufficient to allow for a recovery in fair value. If a decline in fair value is judged to be other than temporary, the cost basis of the individual security is written down to fair value which then becomes the new cost basis. The amount of the write down is included in other-than-temporary impairment of securities in the consolidated statements of income. The new cost basis is not adjusted for subsequent recoveries in fair value, if any. Realized gains and losses on sales of securities are recognized on the specific identification method. Amortization of premiums and accretion of discounts are computed using the interest method. The amortized cost, unrealized gains, unrealized losses and estimated fair values of securities at December 31, 2018 and 2017 , are summarized as follows: December 31, 2018 Amortized Unrealized Dollars in thousands Cost Gains Losses Fair Value Available for Sale Taxable debt securities U.S. Government and agencies and corporations $ 26,303 $ 203 $ 366 $ 26,140 Residential mortgage-backed securities: Government-sponsored agencies 80,883 603 1,177 80,309 Nongovernment-sponsored entities 611 4 1 614 State and political subdivisions General obligations 6,081 — 126 5,955 Other revenues 13,457 17 186 13,288 Corporate debt securities 14,807 9 304 14,512 Asset-backed securities 25,288 10 123 25,175 Total taxable debt securities 167,430 846 2,283 165,993 Tax-exempt debt securities State and political subdivisions General obligations 65,626 624 344 65,906 Water and sewer revenues 20,018 225 98 20,145 Lease revenues 10,980 135 7 11,108 Other revenues 30,197 77 279 29,995 Total tax-exempt debt securities 126,821 1,061 728 127,154 Total available for sale securities $ 294,251 $ 1,907 $ 3,011 $ 293,147 December 31, 2017 Amortized Unrealized Dollars in thousands Cost Gains Losses Fair Value Available for Sale Taxable debt securities U.S. Government and agencies and corporations $ 31,260 $ 498 $ 145 $ 31,613 Residential mortgage-backed securities: Government-sponsored agencies 120,948 1,276 903 121,321 Nongovernment-sponsored entities 2,045 39 7 2,077 State and political subdivisions General obligations 6,090 — 55 6,035 Other revenues 11,657 47 62 11,642 Corporate debt securities 16,375 — 130 16,245 Total taxable debt securities 188,375 1,860 1,302 188,933 Tax-exempt debt securities State and political subdivisions General obligations 65,560 1,530 198 66,892 Water and sewer revenues 23,108 566 3 23,671 Lease revenues 13,024 451 2 13,473 Electric revenues 6,205 128 — 6,333 Sales tax revenues 4,126 140 — 4,266 University revenues 5,272 38 9 5,301 Other revenues 19,101 616 — 19,717 Total tax-exempt debt securities 136,396 3,469 212 139,653 Total available for sale securities $ 324,771 $ 5,329 $ 1,514 $ 328,586 The below information is relative to the five states where issuers with the highest volume of state and political subdivision securities held in our portfolio are located. We own no such securities of any single issuer which we deem to be a concentration.

We principally use credit ratings from Nationally Recognized Statistical Rating Organizations (“NRSROs”) to support analyses of our portfolio of securities issued by state and political subdivisions, as we generally do not purchase securities that are rated below the six highest NRSRO rating categories. In addition to considering a security’s NRSRO rating, we also assess or confirm through an internal review of an issuer’s financial information and other applicable information that: 1) the issuer’s risk of default is low; 2) the characteristics of the issuer’s demographics and economic environment are satisfactory; and 3) the issuer’s budgetary position and stability of tax or other revenue sources are sound. The proceeds from sales, calls and maturities of available for sale securities, including principal payments received on mortgage-backed obligations, and the related gross gains and losses realized are as follows: Dollars in thousands Proceeds from Gross realized Calls and Principal Years ended December 31, Sales Maturities Payments Gains Losses 2018 $ 107,559 $ 1,145 $ 24,814 $ 1,785 $ 1,163 2017 152,882 2,700 31,902 685 699 2016 72,453 3,235 35,881 1,422 295 Residential mortgage-backed obligations having contractual maturities ranging from 1 to 50 years are included in the following maturity distribution schedules based on their anticipated average life to maturity, which ranges from 2 months to 34 years. Accordingly, discounts are accreted and premiums are amortized over the anticipated average life to maturity of the specific obligation. The maturities, amortized cost and estimated fair values of securities at December 31, 2018 , are summarized as follows: Dollars in thousands Amortized Cost Fair Value Due in one year or less $ 27,679 $ 27,635 Due from one to five years 57,718 57,519 Due from five to ten years 48,085 47,205 Due after ten years 160,769 160,788 Total $ 294,251 $ 293,147 At December 31, 2018 and 2017 , securities with estimated fair values of $58.6 million and $113.1 million respectively, were pledged to secure public deposits and for other purposes required or permitted by law. We held 134 available for sale securities having an unrealized loss at December 31, 2018 . We do not intend to sell these securities and it is more likely than not that we will not be required to sell these securities before recovery of their amortized cost bases. We believe that this decline in value is primarily attributable to the lack of market liquidity and to changes in market interest rates and not due to credit quality. Accordingly, no other-than-temporary impairment charge to earnings is warranted at this time.

Investments, All Other Investments [Abstract]
Investments and Other Noncurrent Assets [Text Block]	OTHER INVESTMENTS Equity securities are carried at fair value, with changes in fair value reported in net income. Equity securities without readily determinable fair values are carried at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment. Our equity securities totaled $137,000 at December 31, 2018 and 2017. We are a member bank of the Federal Home Loan Bank ("FHLB") system. Members are required to own a certain amount of stock based on the level of borrowings from FHLB and other factors. FHLB stock is carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. Dividends are reported as income as earned. This stock totaled $13.1 million and $11.00 million at December 31, 2018 and 2017 . We have invested in two limited partnerships which own interests in diversified portfolios of qualified affordable housing projects. Also, we have purchased substantially all the interest in a limited liability company owning a qualified rehabilitated multi-family housing project. As result of these investments, Summit is allocated its proportional share of each investees’ operating losses and Federal Low-Income Housing and Rehabilitation Tax Credits. We use the proportional amortization method to account for each of these investments, whereby the cost of the investment is amortized in proportion to the amount of tax credits and other tax benefits received, and the net investment performance is recognized in the consolidated statement of income as a component of the provision for current income taxes. As of December 31, 2018 and 2017, our carrying value of these investments totaled $3.35 million and $3.89 million , respectively. For the years ended December 31, 2018 , 2017 and 2016, we recognized $1,544,000 , $927,000 and $269,000 in tax credits and other tax benefits, against which we amortized these investments $1.27 million , $680,000 and $214,000 .

Risk-rated loans with insignificant delays or insignificant short falls in the amount of payments expected to be collected are not considered to be impaired. ▪ Loans that have been modified in a troubled debt restructuring. Both commercial and consumer loans are deemed impaired upon being contractually modified in a troubled debt restructuring. Troubled debt restructurings typically result from our loss mitigation activities and occur when we grant a concession to a borrower who is experiencing financial difficulty in order to minimize our economic loss and to avoid foreclosure or repossession of collateral. Once restructured, a loan is generally considered impaired until its maturity, regardless of whether the borrower performs under the modified terms. Although such a loan may be returned to accrual status if the criteria set forth in our accounting policy are met, the loan would continue to be evaluated for an asset-specific allowance for loan losses and we would continue to report the loan in the impaired loan table below. The following tables present loans individually evaluated for impairment at December 31, 2018 and 2017 .

The average recorded investment of impaired loans during 2016 was $37.9 million and $1.3 million interest income was recognized on those loans while impaired. A modification of a loan is considered a troubled debt restructuring (“TDR”) when a borrower is experiencing financial difficulty and the modification constitutes a concession that we would not otherwise consider. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of both. A loan continues to be classified as a TDR for the life of the loan. Included in impaired loans are TDRs of $27 million , of which $26.6 million were current with respect to restructured contractual payments at December 31, 2018 and $28.4 million , all of which were current with respect to restructured contractual payments at December 31, 2017 . There were no commitments to lend additional funds under these restructurings at either balance sheet date. The following table presents by class the TDRs that were restructured during 2018 and 2017 . Generally, the modifications were extensions of term, modifying the payment terms from principal and interest to interest only for an extended period, or reduction in interest rate. All TDRs are evaluated individually for allowance for loan loss purposes. 2018 2017 Dollars in thousands Number of Modifications Pre-modification Recorded Investment Post-modification Recorded Investment Number of Modifications Pre-modification Recorded Investment Post-modification Recorded Investment Commercial 2 $ 157 $ 157 — $ — $ — Commercial real estate Owner-occupied — — — 1 2,302 2,302 Non-owner occupied 2 183 183 2 489 489 Construction and development Land & land development — — — 1 438 438 Residential real estate Non-jumbo 8 899 899 4 642 642 Total 12 $ 1,239 $ 1,239 8 $ 3,871 $ 3,871 The following table presents defaults during the stated period of TDRs that were restructured during the past twelve months.

We analyze loans individually by classifying the loans as to credit risk. We internally grade all commercial loans at the time of loan origination. In addition, we perform an annual loan review on all non-homogenous commercial loan relationships with an aggregate exposure of $2.5 million , at which time these loans are re-graded. We use the following definitions for our risk grades: Pass: Loans graded as Pass are loans to borrowers of acceptable credit quality and risk. They are higher quality loans that do not fit any of the other categories described below. OLEM (Special Mention): Commercial loans categorized as OLEM are potentially weak. The credit risk may be relatively minor yet represent a risk given certain specific circumstances. If the potential weaknesses are not monitored or mitigated, the asset may weaken or inadequately protect our position in the future. Substandard: Commercial loans categorized as Substandard are inadequately protected by the borrower’s ability to repay, equity and/or the collateral pledged to secure the loan. These loans have identified weaknesses that could hinder normal repayment or collection of the debt. These loans are characterized by the distinct possibility that we will sustain some loss if the identified weaknesses are not mitigated. Doubtful: Commercial loans categorized as Doubtful have all the weaknesses inherent in those loans classified as Substandard, with the added elements that the full collection of the loan is improbable and the possibility of loss is high. Loss: Loans classified as loss are considered to be non-collectible and of such little value that their continuance as a bankable asset is not warranted. This does not mean that the loan has absolutely no recovery value, but rather it is neither practical nor desirable to defer writing off the loan, even though partial recovery may be obtained in the future. The following table presents the recorded investment in construction and development, commercial and commercial real estate loans which are generally evaluated based upon our internal risk ratings defined above.

Loans to related parties : We have had, and may be expected to have in the future, banking transactions in the ordinary course of business with our directors, principal officers, their immediate families and affiliated companies in which they are principal shareholders (commonly referred to as related parties). These transactions have been, in our opinion, on the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with others.

Interest on loans is accrued daily on the outstanding balances. Loan origination fees and certain direct loan origination costs are deferred and amortized as adjustments of the related loan yield over its contractual life. We categorize residential real estate loans in excess of $ 600,000 as jumbo loans. Generally, loans are placed on nonaccrual status when principal or interest is greater than 90 days past due based upon the loan's contractual terms. Interest is accrued daily on impaired loans unless the loan is placed on nonaccrual status. Impaired loans are placed on nonaccrual status when the payments of principal and interest are in default for a period of 90 days, unless the loan is both well-secured and in the process of collection. Interest on nonaccrual loans is recognized primarily using the cost-recovery method. Loans may be returned to accrual status when repayment is reasonably assured and there has been demonstrated performance under the terms of the loan or, if applicable, the terms of the restructured loans. Commercial-related loans or portions thereof are charged off to the allowance for loan losses when the loss has been confirmed. This determination is made on a case by case basis considering many factors, including the prioritization of our claim in bankruptcy, expectations of the workout/restructuring of the loan and valuation of the borrower’s equity. We deem a loss confirmed when a loan or a portion of a loan is classified “loss” in accordance with bank regulatory classification guidelines, which state, “Assets classified loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted”. Consumer-related loans are generally charged to the allowance for loan losses upon reaching specified stages of delinquency, in accordance with the Federal Financial Institutions Examination Council policy. For example, credit card loans are charged off by the end of the month in which the account becomes 180 days past due or within 60 days from receiving notification about a specified event (e.g., bankruptcy of the borrower), whichever is earlier. Residential mortgage loans are generally charged off to net realizable value no later than when the account becomes 180 days past due. Other consumer loans, if collateralized, are generally charged off to net realizable value at 120 days past due.

Risk-rated loans with insignificant delays or insignificant short falls in the amount of payments expected to be collected are not considered to be impaired. ▪ Loans that have been modified in a troubled debt restructuring. Both commercial and consumer loans are deemed impaired upon being contractually modified in a troubled debt restructuring. Troubled debt restructurings typically result from our loss mitigation activities and occur when we grant a concession to a borrower who is experiencing financial difficulty in order to minimize our economic loss and to avoid foreclosure or repossession of collateral. Once restructured, a loan is generally considered impaired until its maturity, regardless of whether the borrower performs under the modified terms. Although such a loan may be returned to accrual status if the criteria set forth in our accounting policy are met, the loan would continue to be evaluated for an asset-specific allowance for loan losses and we would continue to report the loan in the impaired loan table below.

The average recorded investment of impaired loans during 2016 was $37.9 million and $1.3 million interest income was recognized on those loans while impaired. A modification of a loan is considered a troubled debt restructuring (“TDR”) when a borrower is experiencing financial difficulty and the modification constitutes a concession that we would not otherwise consider. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of both. A loan continues to be classified as a TDR for the life of the loan. Included in impaired loans are TDRs of $27 million , of which $26.6 million were current with respect to restructured contractual payments at December 31, 2018 and $28.4 million , all of which were current with respect to restructured contractual payments at December 31, 2017 . There were no commitments to lend additional funds under these restructurings at either balance sheet date. The following table presents by class the TDRs that were restructured during 2018 and 2017 . Generally, the modifications were extensions of term, modifying the payment terms from principal and interest to interest only for an extended period, or reduction in interest rate. All TDRs are evaluated individually for allowance for loan loss purposes. 2018 2017 Dollars in thousands Number of Modifications Pre-modification Recorded Investment Post-modification Recorded Investment Number of Modifications Pre-modification Recorded Investment Post-modification Recorded Investment Commercial 2 $ 157 $ 157 — $ — $ — Commercial real estate Owner-occupied — — — 1 2,302 2,302 Non-owner occupied 2 183 183 2 489 489 Construction and development Land & land development — — — 1 438 438 Residential real estate Non-jumbo 8 899 899 4 642 642 Total 12 $ 1,239 $ 1,239 8 $ 3,871 $ 3,871 The following table presents defaults during the stated period of TDRs that were restructured during the past twelve months.

We analyze loans individually by classifying the loans as to credit risk. We internally grade all commercial loans at the time of loan origination. In addition, we perform an annual loan review on all non-homogenous commercial loan relationships with an aggregate exposure of $2.5 million , at which time these loans are re-graded. We use the following definitions for our risk grades: Pass: Loans graded as Pass are loans to borrowers of acceptable credit quality and risk. They are higher quality loans that do not fit any of the other categories described below. OLEM (Special Mention): Commercial loans categorized as OLEM are potentially weak. The credit risk may be relatively minor yet represent a risk given certain specific circumstances. If the potential weaknesses are not monitored or mitigated, the asset may weaken or inadequately protect our position in the future. Substandard: Commercial loans categorized as Substandard are inadequately protected by the borrower’s ability to repay, equity and/or the collateral pledged to secure the loan. These loans have identified weaknesses that could hinder normal repayment or collection of the debt. These loans are characterized by the distinct possibility that we will sustain some loss if the identified weaknesses are not mitigated. Doubtful: Commercial loans categorized as Doubtful have all the weaknesses inherent in those loans classified as Substandard, with the added elements that the full collection of the loan is improbable and the possibility of loss is high. Loss: Loans classified as loss are considered to be non-collectible and of such little value that their continuance as a bankable asset is not warranted. This does not mean that the loan has absolutely no recovery value, but rather it is neither practical nor desirable to defer writing off the loan, even though partial recovery may be obtained in the future.

Allowance For Loan Losses

Allowance For Loan Losses	12 Months Ended

Allowance for Loan and Lease Losses Write-offs, Net [Abstract]
Allowance for Loan Losses	ALLOWANCE FOR LOAN LOSSES The allowance for loan losses is maintained at a level considered adequate to provide for our estimate of probable credit losses inherent in the loan portfolio. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. Loans are charged against the allowance for loan losses when we believe that collectability is unlikely. While we use the best information available to make our evaluation, future adjustments may be necessary if there are significant changes in conditions. The allowance is comprised of three distinct components: (1) specific allowances related to loans individually evaluated, (2) quantitative allowances related to loans collectively evaluated and (3) qualitative allowances related to loans collectively evaluated. A summary of the methodology we employ on a quarterly basis with respect to each of these components in order to evaluate the overall adequacy of our allowance for loan losses is as follows. Specific Allowance for Loans Individually Evaluated First, we identify loan relationships having aggregate balances in excess of $500,000 and that may also have credit weaknesses. Such loan relationships are identified primarily through our analysis of internal loan evaluations, past due loan reports and loans adversely classified internally or by regulatory authorities. Each loan so identified is then individually evaluated to determine whether it is impaired – that is, based on current information and events, it is probable that we will be unable to collect all amounts due in accordance with the contractual terms of the underlying loan agreement. Substantially all of our impaired loans historically have been collateral dependent, meaning repayment of the loan is expected or is considered to be provided solely from the sale of the loan’s underlying collateral. For such loans, we measure impairment based on the fair value of the loan’s collateral, which is generally determined utilizing current appraisals. A specific allowance is established in an amount equal to the excess, if any, of the recorded investment in each impaired loan over the fair value of its underlying collateral, less estimated costs to sell. Our policy is to re-evaluate the fair value of collateral dependent loans at least every twelve months unless there is a known deterioration in the collateral’s value, in which case a new appraisal is obtained. PCI loans are individually evaluated. The evaluation of the PCI loans requires continued quarterly assessment of key assumptions and estimates similar to the initial fair value estimate, including changes in the severity of loss, timing and speed of payments, collateral value changes, expected cash flows and other relevant factors. The quarterly assessment is compared to the initial fair value estimate and a determination is made if an adjustment to the allowance for loan loss is deemed necessary. Quantitative Allowance for Loans Collectively Evaluated Second, we stratify the loan portfolio into eleven loan pools. Quantitative allowances relative to each loan pool are established as follows: for all loan segments an allocation equaling 100% of the respective pool’s average 12 month historical net loan charge-off rate (determined based upon the most recent twelve quarters) is applied to the aggregate recorded investment in the pool of loans. We believe that a twelve month historical loss rate is most indicative of the losses that can be expected. Purchased performing loans are collectively evaluated as their own separate category within each loan pool. The allowance on each pool is compared to the estimated fair value credit discount to determine if this discount remains adequate. If any credit discount is not adequate, additional allowances will be recognized. Qualitative Allowance for Loans Collectively Evaluated Third, we consider the necessity to adjust our average historical net loan charge-off rates relative to each of the above eleven loan pools for potential risks factors that could result in actual losses deviating from prior loss experience. For example, if we observe a significant increase in delinquencies within the conventional mortgage loan pool above historical trends, an additional allocation to the average historical loan charge-off rate is applied.

Property Held For Sale	PROPERTY HELD FOR SALE Property held for sale consists of premises held for sale and real estate acquired through foreclosure on loans secured by such real estate. Qualifying premises are transferred to property held for sale at estimated fair value less anticipated selling costs, establishing a new cost basis. Foreclosed properties are recorded at the lower of the investment in the real estate or estimated fair value less anticipated selling costs based upon the property’s appraised value at the date of foreclosure, with any difference between the fair value of foreclosed property and the carrying value of the related loan charged to the allowance for loan losses. We perform periodic valuations of property held for sale subsequent to transfer. Changes in value subsequent to transfer are recorded in noninterest expense. Gains or losses resulting from the sale of property held for sale is recognized on the date of sale and is included in noninterest expense. Depreciation is not recorded on property held for sale. Expenses incurred in connection with operating foreclosed properties are charged to noninterest expense.

Premises and Equipment	PREMISES AND EQUIPMENT Land is carried at cost, while premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed primarily by the straight-line method for premises and equipment over the estimated useful lives of the assets. The estimated useful lives employed are on average 30 years for premises and 3 to 10 years for furniture and equipment. Repairs and maintenance expenditures are charged to operating expenses as incurred. Major improvements and additions to premises and equipment, including construction period interest costs, are capitalized. No interest was capitalized during 2018 , 2017 , or 2016 . The major categories of premises and equipment and accumulated depreciation at December 31, 2018 and 2017 are summarized as follows: Dollars in thousands 2018 2017 Land $ 10,415 $ 10,061 Buildings and improvements 32,283 29,620 Furniture and equipment 19,783 17,842 62,481 57,523 Less accumulated depreciation 24,928 23,314 Total premises and equipment, net $ 37,553 $ 34,209 Depreciation expense for the years ended December 31, 2018 , 2017 and 2016 approximated $2.17 million , $1.89 million and $1.22 million , respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill and certain other intangible assets with indefinite useful lives are not amortized into net income over an estimated life, but rather are tested at least annually for impairment. Intangible assets determined to have definite useful lives are amortized over their estimated useful lives and also are subject to impairment testing. Effective July 1, 2017, we early adopted ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The adoption of ASU 2017-04 had no impact on our consolidated financial statements. During third quarter 2018, we performed the qualitative assessment of the goodwill of our community banking and insurance services reporting units and determined that the fair values of the reporting units were more likely than not greater than their carrying values. In performing the qualitative assessments, we considered certain events and circumstances specific to each reporting unit, such as macroeconomic conditions, industry and market considerations, overall financial performance and cost factors when evaluating whether it is more likely than not that the fair values of our community banking or insurance services reporting units are less than their carrying values. No indicators of impairment for either reporting unit were noted as of September 30, 2018. The following table presents our goodwill activity by reporting unit for 2018.

Borrowed Funds	BORROWED FUNDS Our subsidiary bank is a member of the Federal Home Loan Bank (“FHLB”). Membership in the FHLB makes available short-term and long-term advances under collateralized borrowing arrangements with each subsidiary bank. All FHLB advances are collateralized primarily by similar amounts of residential mortgage loans, certain commercial loans, mortgage backed securities and securities of U. S. Government agencies and corporations. We had $159.3 million available on a short term line of credit with the Federal Reserve Bank at December 31, 2018 , which is primarily secured by commercial and industrial loans and consumer loans. We also had $6 million available on an unsecured line of credit with a correspondent bank. At December 31, 2018 , our subsidiary bank had additional borrowings availability of $462.8 million from the FHLB. Short-term FHLB advances are granted for terms of 1 to 365 days and bear interest at a fixed or variable rate set at the time of the funding request. Short-term borrowings: At December 31, 2018 , we had $165.3 million borrowing availability through credit lines and Federal funds purchased agreements. Federal funds purchased mature the next business day.

All FHLB advances are collateralized primarily by similar amounts of residential mortgage loans, certain commercial loans, mortgage backed securities and securities of U. S. Government agencies and corporations. Balance at December 31, Dollars in thousands 2018 2017 Long-term FHLB advances $ 735 $ 751 Long-term repurchase agreements — 45,000 Total $ 735 $ 45,751 The average interest rate paid on long-term borrowings during 2018 was 4.26% compared to 4.33% in 2017 . Our long term FHLB borrowings bear both fixed and variable rates and mature in varying amounts through the year 2026. The securities underlying the repurchase agreements are under our control and secure the total outstanding balances. We generally account for securities sold under agreements to repurchase as collateralized financing transactions and record them at the amounts at which the securities were sold, plus accrued interest. Securities, generally U.S. government and Federal agency securities, pledged as collateral under these financing arrangements cannot be sold or repledged by the secured party. The fair value of collateral provided is continually monitored and additional collateral is provided as needed. At December 31, 2017, residential mortgage-backed securities issued by government sponsored agencies with a fair value of $50.0 million were pledged as collateral for the long-term repurchase agreements. Subordinated debentures owed to unconsolidated subsidiary trusts: We have three statutory business trusts that were formed for the purpose of issuing mandatorily redeemable securities (the “capital securities”) for which we are obligated to third party investors and investing the proceeds from the sale of the capital securities in our junior subordinated debentures (the “debentures”). The debentures held by the trusts are their sole assets. Our subordinated debentures totaled $ 19.6 million at December 31, 2018 and 2017 . In October 2002, we sponsored SFG Capital Trust I, in March 2004, we sponsored SFG Capital Trust II and in December 2005, we sponsored SFG Capital Trust III, of which 100% of the common equity of each trust is owned by us. SFG Capital Trust I issued $ 3.5 million in capital securities and $ 109,000 in common securities and invested the proceeds in $ 3.61 million of debentures. SFG Capital Trust II issued $ 7.5 million in capital securities and $ 232,000 in common securities and invested the proceeds in $ 7.73 million of debentures. SFG Capital Trust III issued $ 8.0 million in capital securities and $ 248,000 in common securities and invested the proceeds in $ 8.25 million of debentures. Distributions on the capital securities issued by the trusts are payable quarterly at a variable interest rate equal to 3 month LIBOR plus 345 basis points for SFG Capital Trust I, 3 month LIBOR plus 280 basis points for SFG Capital Trust II and 3 month LIBOR plus 145 basis points for SFG Capital Trust III and equals the interest rate earned on the debentures held by the trusts and is recorded as interest expense by us. The capital securities are subject to mandatory redemption in whole or in part, upon repayment of the debentures. We have entered into agreements which, taken collectively, fully and unconditionally guarantee the capital securities subject to the terms of the guarantee. The debentures of each Capital Trust are redeemable by us quarterly. The capital securities held by SFG Capital Trust I, SFG Capital Trust II and SFG Capital Trust III qualify as Tier 1 capital under Federal Reserve Board guidelines. In accordance with these Guidelines, trust preferred securities generally are limited to 25% of Tier 1 capital elements, net of goodwill. The amount of trust preferred securities and certain other elements in excess of the limit can be included in Tier 2 capital.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS We use derivative instruments primarily to protect against the risk of adverse interest rate movements on the cash flows of certain liabilities. Derivative instruments represent contracts between parties that usually require little or no initial net investment and result in one party delivering cash or another type of asset to the other party based upon a notional amount and an underlying as specified in the contract. A notional amount represents the number of units of a specific item, such as currency units. An underlying represents a variable, such as an interest rate or price index. The amount of cash or other asset delivered from one party to the other is determined based upon the interaction of the notional amount of the contract with the underlying. Derivatives can also be implicit in certain contracts and commitments. As with any financial instrument, derivative instruments have inherent risks, primarily market and credit risk. Market risk associated with changes in interest rates is managed by establishing and monitoring limits as to the degree of risk that may be undertaken as part of our overall market risk monitoring process. Credit risk occurs when a counterparty to a derivative contract with an unrealized gain fails to perform according to the terms of the agreement. Credit risk is managed by monitoring the size and maturity structure of the derivative portfolio and applying uniform credit standards to all activities with credit risk. All derivative instruments are recorded on the balance sheet at fair value in either other assets or other liabilities. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and the type of hedge transaction. Fair value hedges – For transactions in which we are hedging changes in fair value of an asset, liability, or a firm commitment, changes in the fair value of the derivative instrument are generally offset in the income statement by changes in the hedged item’s fair value. Cash flow hedges – For transactions in which we are hedging the variability of cash flows related to a variable-rate asset, liability, or a forecasted transaction, changes in the fair value of the derivative instrument are reported in other comprehensive income. The gains and losses on the derivative instrument, which are reported in comprehensive income, are reclassified to earnings in the periods in which earnings are impacted by the variability of cash flows of the hedged item. The ineffective portion of all hedges is recognized in current period earnings. Our derivatives are governed by the terms of ISDA Master netting agreements and Credit Support Annexes. The ISDA Master agreements allow counterparties to offset trades in a gain against trades in a loss to determine net exposure and allow for the right of offset in the event of either a default or an additional termination event. Credit Support Annexes govern the terms of daily collateral posting practices. Collateral practices mitigate the potential loss impact to affected parties by requiring liquid collateral to be posted on a scheduled basis to secure the aggregate net unsecured exposure. In addition to collateral, the right of offset allows counterparties to offset net derivative values with a defaulting party against certain other contractual receivables from other obligations due to the defaulting party in determining the net termination amount. We have entered into three forward-starting, pay-fixed/receive LIBOR interest rate swaps. $ 40 million notional with an effective date of July 18, 2016, was designated as a cash flow hedge of $ 40 million of forecasted variable rate Federal Home Loan Bank advances. Under the terms of this swap we will pay a fixed rate of 2.98% for a 3 year period. $ 30 million notional with an effective date of April 18, 2016, was designated as a cash flow hedge of $ 30 million of forecasted variable rate Federal Home Loan Bank advances. Under the terms of this swap we will pay a fixed rate of 2.89% for a 4.5 year period. $ 40 million notional with an effective date of October 18, 2016, was designated as a cash flow hedge of $ 40 million of forecasted variable rate Federal Home Loan Bank advances. Under the terms of this swap we will pay a fixed rate of 2.84% for a 3 year period. We have entered into two pay fixed/receive variable interest rate swaps to hedge the fair value variability of two commercial fixed rate loans with the same principal, amortization and maturity terms of the underlying loans, which are designated as fair value hedges. Under the terms of a $9.95 million original notional swap with an effective date of January 15, 2015, we will pay a fixed rate of 4.33% for a 10 year period. Under the terms of an $11.3 million original notional swap with an effective date of December 18, 2015, we will pay a fixed rate of 4.30% for a 10 year period.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Income taxes, computed on the separate return basis with the benefit of filing a consolidated return being recorded at the holding company, include Federal and state income taxes and are based on pretax net income reported in the consolidated financial statements, adjusted for transactions that may never enter into the computation of income taxes payable (permanent differences). Deferred tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Valuation allowances are established, when deemed necessary, to reduce deferred tax assets to the amount expected to be realized. On December 22, 2017, the Tax Cuts and Jobs Act (“TCJA”) was signed into law. Among other things, the TCJA permanently lowered the federal corporate income tax rate to 21% from the prior maximum rate of 35% , effective January 1, 2018. As a result of the reduction of the federal corporate income tax rate, ASC 740 - Income Taxes , required us to remeasure our deferred tax assets and deferred tax liabilities, including those accounted for in accumulated other comprehensive income, as of the date of TCJA’s enactment and record the effects as income tax expense in the reporting period of enactment. We remeasured our deferred tax assets and deferred tax liabilities as of December 22, 2017, at the new federal corporate income tax rate of 21% , and recorded additional deferred federal income tax expense of $3.5 million to reduce our net deferred tax assets. A tax position that meets a "probable recognition threshold" for the benefit of the uncertain tax position is recognized in the financial statements. A tax position that fails to meet the probable recognition threshold will result in either reduction of a current or deferred tax asset or receivable, or recording a current or deferred tax liability. We concluded that there were no significant uncertain tax positions requiring recognition in the consolidated financial statements. The evaluation was performed for the years ended 2015 through 2018, the tax years which remain subject to examination by major tax jurisdictions. The components of applicable income tax expense for the years ended December 31, 2018 , 2017 and 2016 , are as follows: Dollars in thousands 2018 2017 2016 Current Federal $ 6,400 $ 5,092 $ 7,738 State 973 496 627 7,373 5,588 8,365 Deferred Federal (304 ) 4,027 (353 ) State (45 ) 49 (4 ) (349 ) 4,076 (357 ) Total $ 7,024 $ 9,664 $ 8,008 Reconciliation between the amount of reported income tax expense and the amount computed by multiplying the statutory income tax rates by book pretax income for the years ended December 31, 2018 , 2017 and 2016 is as follows: 2018 2017 2016 Dollars in thousands Amount Percent Amount Percent Amount Percent Computed tax at applicable statutory rate $ 7,370 21 $ 7,553 35 $ 8,857 35 Increase (decrease) in taxes resulting from: Tax-exempt interest and dividends, net (1,011 ) (3 ) (1,569 ) (7 ) (1,080 ) (4 ) Non-deductible merger-related expenses — — — — 108 — Low-income housing and rehabilitation tax credits (286 ) (1 ) (247 ) (1 ) (55 ) — Impact of enacted income tax rate change — — 3,461 16 — — State income taxes, net of Federal income tax benefit 734 2 354 2 405 2 Other, net 217 1 112 — (227 ) (1 ) Applicable income taxes $ 7,024 20 $ 9,664 45 $ 8,008 32 Deferred income taxes reflect the impact of "temporary differences" between amounts of assets and liabilities for financial reporting purposes and such amounts as measured for tax purposes. Deferred tax assets and liabilities represent the future tax return consequences of temporary differences, which will either be taxable or deductible when the related assets and liabilities are recovered or settled. The tax effects of temporary differences, which give rise to our deferred tax assets and liabilities as of December 31, 2018 and 2017 , are as follows: Dollars in thousands 2018 2017 Deferred tax assets Allowance for loan losses $ 2,921 $ 2,753 Depreciation 405 523 Foreclosed properties 2,951 2,964 Deferred revenue 18 39 Deferred compensation 2,490 2,325 Other deferred costs and accrued expenses 645 551 Net unrealized loss on securities available for sale 265 — Net unrealized loss on interest rate swaps 99 494 Capital loss carryforwards 166 166 Total 9,960 9,815 Deferred tax liabilities Accretion on tax-exempt securities 29 — Net unrealized gain on securities available for sale — 916 Other post-retirement benefits 44 125 Purchase accounting adjustments and goodwill 2,253 2,357 Total 2,326 3,398 Net deferred tax assets $ 7,634 $ 6,417 We may from time to time be assessed interest or penalties associated with tax liabilities by major tax jurisdictions, although any such assessments are estimated to be minimal and immaterial. To the extent we have received an assessment for interest and/or penalties; it has been classified in the consolidated statements of income as a component of other noninterest expense. We are currently open to audit under the statute of limitations by the Internal Revenue Service for the years ended December 31, 2015 through 2017. Tax years 2016 through 2017 remain subject to West Virginia State examination.

Employee Benefits and Share-based Compensation, Noncash [Abstract]
Employee Benefits	EMPLOYEE BENEFITS Retirement Plans: We have defined contribution profit-sharing plans with 401(k) provisions covering substantially all employees. Contributions to the plans are at the discretion of the Board of Directors. Contributions made to the plans and charged to expense were $622,000 , $556,000 and $381,000 for the years ended December 31, 2018 , 2017 and 2016 , respectively. Employee Stock Ownership Plan: We have an Employee Stock Ownership Plan (“ESOP”), which enables eligible employees to acquire shares of our common stock. The cost of the ESOP is borne by us through annual contributions to an Employee Stock Ownership Trust in amounts determined by the Board of Directors. The expense recognized by us is based on cash contributed or committed to be contributed by us to the ESOP during the year. Contributions to the ESOP for the years ended December 31, 2018 , 2017 and 2016 were $646,000 , $525,000 and $484,000 respectively. Dividends paid by us to the ESOP are reported as a reduction of retained earnings. The ESOP owned 588,193 shares of our common stock at December 31, 2018 and 2017 , all of which were purchased at the prevailing market price. All but 86,954 unallocated shares at December 31, 2018 are considered outstanding for earnings per share computations. The purchase of unallocated ESOP shares is shown as a reduction of shareholders' equity, similar to a purchase of treasury stock. The loan receivable from the ESOP to the Company is not reported as an asset nor is the debt of the ESOP reported as a liability on the Company's Consolidated Balance Sheets. Cash dividends on allocated shares (those credited to ESOP participants' accounts) are recorded as a reduction of shareholders' equity and distributed directly to participants' accounts. Cash dividends on unallocated shares (those held by the ESOP not yet credited to participants' accounts) are used to pay a portion of the ESOPs debt service requirements. Unallocated ESOP shares will be allocated to ESOP participants ratably as the ESOP's loan is repaid. When the shares are committed to be released and become available for allocation to plan participants, the then fair value of such shares will be charged to compensation expense. The ESOP shares as of December 31 are as follows: ESOP Shares At December 31, 2018 2017 Allocated shares 481,459 441,654 Shares committed to be released 19,780 39,805 Unallocated shares 86,954 106,734 Total ESOP shares 588,193 588,193 Market value of unallocated shares ( in thousands ) $ 1,679 $ 2,809 Supplemental Executive Retirement Plan: We have certain non-qualified Supplemental Executive Retirement Plans (“SERP”) with certain senior officers, which provide participating officers with an income benefit payable at retirement age or death. The liabilities accrued for the SERP’s at December 31, 2018 and 2017 were $6.1 million and $5.5 million , respectively, which are included in other liabilities. Included in salaries, commissions and employee benefits was $669,000 , $707,000 and $575,000 expense related to these SERPS for the years December 31, 2018, 2017 and 2016, respectively. Share-Based Compensation: The 2014 Long-Term Incentive Plan (“2014 LTIP”) was adopted by our shareholders in May 2014 to enhance the ability of the Company to attract and retain exceptionally qualified individuals to serve as key employees. The LTIP provides for the issuance of up to 500,000 shares of common stock, in the form of equity awards including stock options, restricted stock, restricted stock units, stock appreciation rights ("SARs"), performance units, other share-based awards or any combination thereof, to our key employees. Stock options awarded under the 2009 Officer Stock Option Plan and the 1998 Officer Stock Option Plan (collectively, the “Plans”) were not altered by the 2014 LTIP and remain subject to the terms of the Plans. However, under the terms of the 2014 LTIP, all shares of common stock remaining issuable under the Plans at the time the 2014 LTIP was adopted ceased to be available for future issuance. Under the 2014 LTIP and the Plans, stock options and SARs have generally been granted with an exercise price equal to the fair value of Summit's common stock on the grant date. We periodically grant share based compensation to individual employees. There were no grants of stock options or SARs in 2018. During first quarter 2017, we granted 34,306 SARs with a $14.06 grant date fair value per SAR that become exercisable ratably over seven years ( 14.3% per year) and expire ten years after the grant date. Also during first quarter 2017, we granted 53,309 SARs with a $14.10 grant date fair value per SAR that become exercisable ratably over five years ( 20% per year) and expire ten years after the grant date. There were no grants of stock options or SARs in 2016. The fair value of our employee stock options and SARs granted under the Plans is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. Additionally, there may be other factors that would otherwise have a significant effect on the value of employee stock options and SARs granted but are not considered by the model. Because our employee stock options and SARs have characteristics significantly different from those of traded options and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options and SARs at the time of grant. The assumptions used to value SARs are as follows: 2017 grant with 7 year expiration 2017 grant with 5 year expiration Risk-free interest rate 2.24 % 2.16 % Expected dividend yield 1.45 % 1.45 % Expected common stock volatility 59.60 % 60.05 % Expected life 7 years 6.5 years We recognize compensation expense based on the estimated number of stock awards expected to actually vest, exclusive of the awards expected to be forfeited. During 2018, 2017 and 2016, our stock compensation expense totaled $391,000 , $385,000 and $200,000 , respectively, and the related income tax benefits recognized in 2018, 2017 and 2016 were $94,000 , $142,000 and $74,000 respectively. A summary of activity in our Plans during 2016 , 2017 and 2018 is as follows: Weighted Average Dollars in thousands, except per share amounts Options / SARs Aggregate Remaining Contractual Term (Yrs.) Exercise Price Outstanding, December 31, 2015 244,147 $ 14.05 Granted — — Exercised (24,740 ) 18.08 Forfeited — — Expired (1,550 ) 18.79 Outstanding, December 31, 2016 217,857 $ 13.56 Granted 87,615 26.01 Exercised (51,781 ) 13.62 Forfeited — — Expired (3,400 ) 24.97 Outstanding, December 31, 2017 250,291 $ 17.75 Granted — — Exercised (6,800 ) 17.79 Forfeited (3,200 ) 25.50 Expired (8,200 ) 25.54 Outstanding, December 31, 2018 232,091 $ 1,070 6.74 $ 17.36 Exercisable Options/SARs: December 31, 2018 95,924 $ 583 6.04 $ 14.82 December 31, 2017 62,646 687 4.92 $ 15.35 December 31, 2016 84,483 974 4.73 $ 16.00 The total intrinsic value of options and SARs exercised in 2018, 2017 and 2016 was $24,000 , $694,000 and $240,000 , respectively. The total fair value of options and SARs vested during 2018, 2017 and 2016 was $396,000 , $200,000 and $200,000 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Off-Balance Sheet Arrangements We are a party to certain financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of our customers. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the statement of financial position. The contract amounts of these instruments reflect the extent of involvement that we have in this class of financial instruments. Many of our lending relationships contain both funded and unfunded elements. The funded portion is reflected on our balance sheet. The unfunded portion of these commitments is not recorded on our balance sheet until a draw is made under the loan facility. Since many of the commitments to extend credit may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash flow requirements. A summary of the total unfunded, or off-balance sheet, credit extension commitments follows: Dollars in thousands December 31, December 31, Commitments to extend credit: Revolving home equity and credit card lines $ 69,893 $ 69,187 Construction loans 85,392 44,323 Other loans 161,619 112,193 Standby letters of credit 6,366 3,870 Total $ 323,270 $ 229,573 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. We evaluate each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if we deem necessary upon extension of credit, is based on our credit evaluation. Collateral held varies but may include accounts receivable, inventory, equipment or real estate. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party and generally are of a term of no greater than one year. Our exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. We use the same credit policies in making commitments and conditional obligations as we do for on-balance sheet instruments. Operating leases We occupy certain facilities under long-term operating leases. The aggregate minimum annual rental commitments under those leases total approximately $200,000 in 2019 and $53,000 in 2020. Total net rent expense included in the accompanying consolidated financial statements was $305,000 in 2018, $284,000 in 2017 and $256,000 in 2016. Employment Agreements We have various employment agreements with our executive officers and other key employees. These agreements contain change in control provisions that would entitle the officers to receive compensation in the event there is a change in control in the Company (as defined) and a termination of their employment without cause (as defined). Legal Contingencies On May 13, 2014, the ResCap Liquidating Trust (“ResCap”), as successor to Residential Funding Company, LLC f/k/a Residential Funding Corporation (“RFC”), filed a complaint against Summit Financial Mortgage, LLC (“Summit Mortgage”), a former residential mortgage subsidiary of Summit whose operations were discontinued in 2007. On January 23, 2017, ResCap, as successor to RFC, filed a complaint against Summit Community Bank, Inc., as successor to Shenandoah Valley Community Bank (“Summit”), in the United States District Court for the District of Minnesota. On April 24, 2017, Summit entered into a Settlement and Release Agreement (the “Settlement Agreement”) with the RFC parties with respect to both of the above reference ResCap lawsuits. Under the Settlement Agreement, Summit paid $9.9 million to fully resolve all claims by ResCap, and to avoid the further costs, disruption, and distraction of defending the ResCap lawsuits. Summit recorded a charge to noninterest expense in its consolidated statement of income for the year December 31, 2017 to recognize this settlement. We are not a party to any other litigation except for matters that arise in the normal course of business. While it is impossible to ascertain the ultimate resolution or range of financial liability, if any, with respect to these contingent matters, in the opinion of management, the outcome of these matters will not have a significant adverse effect on the consolidated financial statements.

Regulatory Matters

Banking and Thrift [Abstract]
Regulatory Matters	REGULATORY MATTERS The primary source of funds for our dividends paid to our shareholders is dividends received from our subsidiaries. Dividends paid by the subsidiary bank are subject to restrictions by banking law and regulations and require approval by the bank’s regulatory agency if dividends declared in any year exceed the bank’s current year's net income, as defined, plus its retained net profits of the two preceding years. During 2019, the Bank will have $25.6 million plus net income for the interim periods through the date of declaration, available for dividends for distribution to us. Our subsidiary bank is required to maintain reserve balances with the Federal Reserve Bank. The required reserve balance was $1,603,000 at December 31, 2018 . Our bank subsidiary, Summit Community Bank, Inc. (“Summit Community”), is subject to various regulatory capital requirements administered by the banking regulatory agencies. Under the capital adequacy guidelines and the regulatory framework for prompt corrective action, Summit Community must meet specific capital guidelines that involve quantitative measures of its assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Our bank subsidiary’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require Summit Community to maintain minimum amounts and ratios of Common Equity Tier 1("CET1"), Total capital and Tier I capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier I capital (as defined) to average assets (as defined). We believe, as of December 31, 2018, that our bank subsidiary met all capital adequacy requirements to which they were subject. The most recent notifications from the banking regulatory agencies categorized Summit Community as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, Summit Community must maintain minimum CET1, Total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the table below. The Basel III Capital Rules became effective for us on January 1, 2015, with full compliance with all of the final rule's requirements phased-in over a multi-year schedule, to be fully phased-in by January 1, 2019. As of December 31, 2018, Summit Community’s capital levels remained characterized as "well-capitalized" under the new rules. See the Capital Requirements section included in Part I, Item 1 -- Business for further discussion of Basel III. On August 28, 2018, the Federal Reserve Board (the “Board”) issued an interim final rule expanding the applicability of the Board's small bank holding company policy statement, as required by the Economic Growth, Regulatory Relief, and Consumer Protection Act of 2018. The interim final rule raises the small bank holding company policy statement's asset threshold from $1 billion to $3 billion in total consolidated assets, and as a result, our holding company was exempted from all regulatory capital guidelines, to which it previously had been subject, until such time as its consolidated assets exceed $3 billion. The following table presents Summit's, as well as Summit Community's, actual and required minimum capital amounts and ratios as of December 31, 2018 and 2017 under the Basel III Capital Rules. The minimum required capital levels presented below reflect the minimum required capital levels (inclusive of the full capital conservation buffers) that will be effective as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. Our actual capital amounts and ratios as well as our subsidiary, Summit Community Bank’s (“Summit Community”) are presented in the following table.

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION We operate three business segments: community banking, insurance services and trust and wealth management services. These segments are primarily identified by the products or services offered. The community banking segment consists of our full service banks which offer customers traditional banking products and services through various delivery channels. The insurance services segment includes two insurance agency offices that sell insurance products. The trust and wealth management segment includes Summit Community Bank's trust division and other non-bank investment products. The accounting policies discussed throughout the notes to the consolidated financial statements apply to each of our business segments. Inter-segment revenue and expense consists of management fees allocated to the community banking, insurance services and trust and wealth management segments for all centralized functions that are performed by the parent, including overall direction in the areas of strategic planning, investment portfolio management, asset/liability management, financial reporting and other financial and administrative services.

Revenue from Contracts with Customers [Abstract]
Revenue from Contracts with Customers	REVENUE FROM CONTRACTS WITH CUSTOMERS I nterest income, loan fees, realized securities gains and losses, bank owned life insurance income and mortgage banking revenue are not in the scope of ASC Topic 606, Revenue from Contracts with Customers . With the exception of gains or losses on sales of foreclosed properties, all of our revenue from contracts with customers in the scope of ASC 606 is recognized within Noninterest Income in the Consolidated Statements of Income. Incremental costs of obtaining a contract are expensed when incurred when the amortization period is one year or less. As of December 31, 2018, remaining performance obligations consisted of insurance products with an original expected length of one year or less. A description of our significant sources of revenue accounted for under ASC 606 follows: Service fees on deposit accounts are fees we charge our deposit customers for transaction-based, account maintenance and overdraft services. Transaction-based fees, which are earned based on specific transactions or customer activity within a customer’s deposit account, are recognized at the time the related transaction or activity occurs, as it is at this point when we fulfill the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which Summit satisfied the performance obligation. Overdraft fees are recognized when the overdraft occurs. Service fees on deposit accounts are paid through a direct charge to the customer’s account. Bank card revenue is comprised of interchange revenue and ATM fees. Interchange revenue is earned when Summit’s debit and credit cardholders conduct transactions through Mastercard and other payment networks. Interchange fees represent a percentage of the underlying cardholder’s transaction value and are generally recognized daily, concurrent with the transaction processing services provided to the cardholder. ATM fees are earned when a non-Summit cardholder uses a Summit ATM. ATM fees are recognized daily, as the related ATM transactions are settled. Trust and wealth management fees consist of 1) trust fees and 2) commissions earned from an independent, third-party broker-dealer. We earn trust fees from our contracts with trust clients to administer or manage assets for investment. Trust fees are earned over time (generally monthly) as Summit provides the contracted services and are assessed based on the value of assets under management at each month-end. We earn commissions from investment brokerage services provided to our clients by an independent, third-party broker-dealer. We receive monthly commissions from the third-party broker-dealer based upon client activity for the previous month. Insurance commissions principally consist of commissions we earn as agents of insurers for selling group employee benefit and property and casualty insurance products to clients. Group employee benefit insurance commissions are recognized over time (generally monthly) as the related customary implied servicing obligations of group policyholders are fulfilled. Property and casualty insurance commissions are recognized using methods which approximate the time of placement of the underlying policy. We are paid insurance commissions ratably as the related policy premiums are paid by clients. The following table illustrates our total non-interest income segregated by revenues within the scope of ASC Topic 606 and those which are within the scope of other ASC Topics: For the Year Ended December 31, Dollars in thousands 2018 2017 2016 Service fees on deposit accounts $ 4,631 $ 4,109 $ 2,656 Bank card revenue 3,152 2,697 1,869 Trust and wealth management fees 2,653 1,863 449 Insurance commissions 4,320 4,005 4,022 Other 246 227 137 Net revenue from contracts with customers 15,002 12,901 9,133 Non-interest income within the scope of other ASC topics 2,420 1,526 2,467 Total noninterest income $ 17,422 $ 14,427 $ 11,600 Gain or loss on sale of foreclosed properties is recorded when control of the property transfers to the buyer, which generally occurs at the time of transfer of the deed. If Summit finances the sale of a foreclosed property to the buyer, we assess whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the foreclosed property is derecognized and the gain or loss on sale is recorded upon transfer of control of the property to the buyer. For the years ended December 31, 2018, 2017 and 2016 net (losses)/gains on sales of foreclosed properties were ($82,000) , $157,000 and $916,000 , respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of estimates	Use of estimates : We must make estimates and assumptions that affect the reported amounts and disclosures in preparing our financial statements in conformity with accounting principles generally accepted in the United States of America. Actual results could differ significantly from those estimates.
Principles of consolidation	Principles of consolidation : The accompanying consolidated financial statements include the accounts of Summit and its wholly-owned subsidiaries. All significant accounts and transactions among these entities have been eliminated.
Comprehensive Income, Policy	Comprehensive income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, cash flow hedges and other post-retirement benefits, which are recognized as separate components of equity.
Cash and cash equivalents	Cash and cash equivalents: Cash and cash equivalents includes cash on hand, amounts due from banks (including cash items in process of clearing), interest bearing deposits with other banks and federal funds sold.
Finance, Loan and Lease Receivables, Held-for-sale, Policy	Loans held for sale : Loans held for sale are valued at the lower of aggregate carrying cost or fair value. Gains or losses realized on the sales of loans are recognized in other income at the time of sale.
Cash surrender value of life insurance policies	Cash surrender value of life insurance policies: We have purchased life insurance policies on certain employees. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Presentation of cash flows	Presentation of cash flows : For purposes of reporting, cash flows from demand deposits, NOW accounts, savings accounts and short-term borrowings are reported on a net basis, since their original maturities are less than three months. Cash flows from loans and certificates of deposit and other time deposits are reported net.
Advertising	Advertising: Advertising costs are expensed as incurred
Trust services	Trust services : Assets held in an agency or fiduciary capacity are not our assets and are not included in the accompanying consolidated balance sheets. Trust services income is recognized on the cash basis in accordance with customary banking practice. Reporting such income on a cash basis does not produce results that are materially different from those that would result from use of the accrual basis.
Variable interest entities	Unconsolidated subsidiary trusts: In accordance with accounting principles generally accepted in the United States, we do not consolidate subsidiary trusts which issue guaranteed preferred beneficial interests in subordinated debentures (Trust Preferred Securities). The Trust Preferred Securities qualify as Tier 1 capital for regulatory purposes. See Note 13 of our Notes to Consolidated Financial Statements for a discussion of our subordinated debentures owed to unconsolidated subsidiary trusts.
