Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Nature of Business: SmartFinancial, Inc. (the "Company") is a bank holding company whose principal activity is the ownership and management of its wholly-owned subsidiary, SmartBank (the "Bank"). The Company provides a variety of financial services to individuals and corporate customers through its offices in East and Middle Tennessee, Alabama and Florida panhandle. The Company’s primary deposit products are interest-bearing demand deposits, savings and money market deposits, and time deposits. Its primary lending products are commercial, residential, and consumer loans. ​ Basis of Presentation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation. ​ Accounting Estimates: In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of other real estate owned, deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and business combination elements (Day 1 and Day 2 Valuation). ​ Cash and Cash Equivalents: For purposes of reporting consolidated cash flows, cash and due from banks includes cash on hand, cash items in process of collection and amounts due from banks. Cash and cash equivalents also includes interest-bearing deposits in banks and federal funds sold. Cash flows from loans, federal funds sold, securities sold under agreements to repurchase and deposits are reported net. The in cash or on deposit Bank is required to maintain average balances with the Federal Reserve Bank. During 2020 the Federal Reserve Bank suspended reserve requirements to provide relief related to the COVID-19 pandemic, thus the Bank did not have a reserve requirement at December 31, 2021 and 2020, respectively. ​ Securities: Securities are classified based on management’s intention on the date of purchase. All debt securities classified as available-for-sale are recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Securities that the Company has both the positive intent and ability to hold to maturity are classified as held-to-maturity and are carried at historical cost and adjusted for amortization of premiums and accretion of discounts. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Transfers of investments securities into the held-to-maturity category from the available-for-sale category are made at fair value at the date of transfer. The unrealized holdings gain or loss at the date of transfer is retained in accumulated other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts are amortized over the remaining life of the security. The Company evaluates securities quarterly for other than temporary impairment using relevant accounting guidance specifying that (a) if the Company does not have the intent to sell a debt security prior to recovery and (b) it is more likely than not that it will not have to sell the debt security prior to recovery, the security would not be considered other than temporarily impaired unless a credit loss has occurred in the security. If management does not intend to sell the security and it is more likely than not that they will not have to sell the security before recovery of the cost basis, management will recognize the credit component of an other-than- temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. Securities borrowed or purchased under agreements to resell and securities loaned or sold under agreements to repurchase are treated as collateralized financial transactions. These agreements are recorded at the amount at which the securities were acquired or sold plus accrued interest. It is the Company’s policy to take possession of securities purchased under resale agreements. The market value of these securities is monitored, and additional securities are obtained when deemed appropriate to ensure such transactions are adequately collateralized. The Company also monitors its exposure with respect to securities sold under repurchase agreements, and a request for the return of excess securities held by the counterparty is made when deemed appropriate. ​ Other Investments: The Company is required to maintain an investment in capital stock of various entities, including the Federal Home Loan Bank and Federal Reserve Bank. Based on redemption provisions of these entities, the stock has no quoted market value and is carried at cost. At their discretion, these entities may declare dividends on the stock. Management reviews restricted investments for impairment based on the ultimate recoverability of the cost basis in these stocks. ​ Loans Held for Sale: Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Gains and losses on sales of loans held for sale are included in the Consolidated Statements of Income in mortgage banking. Loans held for sale are sold to investors with best effort intent and ability to sell loans as long as they meet the underwriting standards of the potential investor. ​ Loans and Leases: Originated loans and leases for which management has the intent and ability to hold for the foreseeable future or until maturity or payoff are carried at the principal amount outstanding net of any unearned income, charge-offs and unamortized fees and costs. Nonrefundable fees collected and certain direct costs incurred related to loan and lease originations are deferred and recorded as an adjustment to loans and leases outstanding. The net amount of the nonrefundable fees and costs is amortized to interest income over the contractual lives using methods that approximate a constant yield. ​ The accrual of interest on loans and leases is discontinued when, in management’s opinion, the borrower may be unable to meet the contractual terms of the obligation payments as they become due, or at the time the loan or lease is 90 days past due, unless the loan is well-secured and in the process of collection. Unsecured loans and leases are typically charged off no later than 120 days past due. Past due status is based on contractual terms of the loan or lease. In all cases, loans and leases are placed on nonaccrual or charged-off at an earlier date if collection of principal and interest is considered doubtful. All interest accrued but not collected for loans and leases that are placed on nonaccrual or charged off is reversed against interest income, unless management believes that the accrual of interest is recoverable through the liquidation of collateral. Interest income on nonaccrual loans and leases is recognized on the cash basis, until the loans or leases are returned to accrual status. Loans and leases are returned to accrual status when all the principal and interest amounts contractually due are brought current and the loan or lease has been performing according to the contractual terms for a period of not less than six months. ​ Acquired Loans: Acquired loans and leases are those acquired in business combinations by the Company or Bank. The fair values of acquired loans and leases with evidence of credit deterioration, Purchased Credit Impaired loans and leases (“PCI loans and leases”), are recorded net of a nonaccretable discount and accretable discount. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized in interest income over the remaining life of the loan or lease when there is reasonable expectation about the amount and timing of such cash flows. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is the nonaccretable discount, which is included in the carrying amount of acquired loans and leases. Subsequent decreases to the expected cash flows will generally result in a provision for loan and lease losses. Subsequent significant increases in cash flows result in a reversal of the provision for loan and lease losses to the extent of prior charges or a reclassification of the difference from nonaccretable to accretable with a positive impact on the accretable discount. Acquired loans and leases are initially recorded at fair value at acquisition date. Accretable discounts related to certain fair value adjustments are accreted into income over the estimated lives of the loans or leases. The Company accounts for PCI loans and leases acquired in the acquisition using the expected cash flows method of recognizing discount accretion based on the acquired loans and leases expected cash flows. Management recasts the estimate of cash flows expected to be collected on each acquired impaired loan and lease pool periodically. If the present value of expected cash flows for a pool is less than its carrying value, an impairment is recognized by an increase in the allowance for loan and lease losses and a charge to the provision for loan and lease losses. If the present value of expected cash flows for a pool is greater than its carrying value, any previously established allowance for loan and lease losses is reversed and any remaining difference increases the accretable yield which will be taken into interest income over the remaining life of the loan or lease pool. Purchased performing loans and leases are recorded at fair value, including a credit discount or premium. Credit losses on acquired performing loans and leases are estimated based on analysis of the performing portfolio at the time of purchase. Such estimated credit losses are recorded as nonaccretable discounts in a manner similar to purchased impaired loans and leases. The fair value discount other than for credit loss is accreted as an adjustment to yield over the estimated lives of the loans and leases. A provision for loan and lease losses is recorded for any deterioration in these loans or leases subsequent to the acquisition. ​ Allowance for Loan and Lease Losses: The allowance for loan and lease losses is established as losses are estimated to have occurred through a provision for loan and lease losses charged to expense. Loan and lease losses are charged against the allowance when management believes the uncollectibility of a loan or lease balance is confirmed. Confirmed losses are charged off immediately. Subsequent recoveries, if any, are credited to the allowance. The allowance is an amount that management believes will be adequate to absorb estimated losses relating to specifically identified loans and leases, as well as probable credit losses inherent in the balance of the loan and lease portfolio. The allowance for loan and lease losses is evaluated on a regular basis by management and is based upon management’s periodic review of the uncollectibility of loans and leases in light of historical experience, the nature and volume of the loan and lease portfolio, overall portfolio quality, review of specific problem loans or leases, current economic conditions that may affect the borrower’s ability to pay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. This evaluation does not include the effects of expected losses on specific loans or leases or groups of loans or leases that are related to future events or expected changes in economic conditions. The allowance consists of specific and general components. The specific component relates to loans and leases that are classified as impaired. For impaired loans and leases, an allowance is established when the discounted cash flows, collateral value, or observable market price of the impaired loan or lease is lower than the carrying value of that loan or lease. The general component covers non-impaired loans and leases and is based on the Company’s historical loss experience adjusted for other qualitative factors. Other adjustments may be made to the allowance for pools of loans and leases after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. An unallocated component may be maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. As part of the risk management program, an independent review is performed on the loan and lease portfolio according to policy, which supplements management’s assessment of the loan and lease portfolio and the allowance for loan or lease losses. The result of the independent review is reported directly to the Audit Committee of the Board of Directors. Loans and leases, for which the terms have been modified at the borrower’s request, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. A loan or lease is considered impaired when it is probable, based on current information and events, the Company will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan or lease agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest when due. Loans and leases that experience insignificant payment delays and payment shortfalls are not classified as impaired. Impaired loans and leases are measured by either the present value of expected future cash flows discounted at the loans or leases effective interest rate, the loans or leases obtainable market price, or the fair value of the collateral if the loan or lease is collateral dependent. Interest on accruing impaired loans or leases is recognized as long as such loans or leases do not meet the criteria for nonaccrual status. Large groups of smaller balance homogeneous loans and leases are collectively evaluated for impairment. The Company’s homogeneous loan and lease pools include consumer real estate loans, commercial real estate loans, construction and land development loans, commercial and industrial loans, leases and consumer and other loans. The general allocations to these loan and lease pools are based on the historical loss rates for specific loan and lease types and the internal risk grade, if applicable, adjusted for both internal and external qualitative risk factors. ​ Troubled Debt Restructurings: The Company designates loan modifications as Troubled Debt Restructurings ("TDRs") when for economic and legal reasons related to the borrower’s financial difficulties, it grants a concession to the borrower that it would not otherwise consider. TDRs can involve loans remaining on nonaccrual, moving to nonaccrual, or continuing on accrual status, depending on the individual facts and circumstances of the borrower. In circumstances where the TDR involves charging off a portion of the loan balance, the Company typically classifies these restructurings as nonaccrual. In connection with restructurings, the decision to maintain a loan that has been restructured on accrual status is based on a current, well documented credit evaluation of the borrower’s financial condition and prospects for repayment under the modified terms. This evaluation includes consideration of the borrower’s current capacity to pay, which among other things may include a review of the borrower’s current financial statements, an analysis of global cash flow sufficient to pay all debt obligations, a debt to income analysis, and an evaluation of secondary sources of payment from the borrower and any guarantors. This evaluation also includes an evaluation of the borrower’s current willingness to pay, which may include a review of past payment history, an evaluation of the borrower’s willingness to provide information on a timely basis, and consideration of offers from the borrower to provide additional collateral or guarantor support. The credit evaluation also reflects consideration of the borrower’s future capacity and willingness to pay, which may include evaluation of cash flow projections, consideration of the adequacy of collateral to cover all principal and interest, and trends indicating improving profitability and collectability of receivables. Restructured nonaccrual loans may be returned to accrual status based on a current, well-documented credit evaluation of the borrower’s financial condition and prospects for repayment under the modified terms. This evaluation must include consideration of the borrower’s sustained historical repayment for a reasonable period, generally a minimum of six months, prior to the date on which the loan is returned to accrual status. ​ Other Real Estate Owned: Other real estate owned acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less selling costs. Any write-down to fair value less cost to sell, at the time of transfer to other real estate owned is charged to the allowance for loan losses. Subsequent to foreclosure valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less costs to sell. Costs of improvements are capitalized, whereas costs relating to holding other real estate owned and subsequent write-downs to the value are expensed. As of December 31, 2021, the were no residential real estate properties where physical possession had been obtained and included with in other real estate owned assets and one property for $26 thousand at December 31, 2020. There were no residential real estate loans in the process of foreclosure at December 31, 2021, and five totaling $384 thousand at December 31, 2020. Premises and Equipment: Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets or the expected terms of the leases, if shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Gains and losses on dispositions are included in current operations. ​ Goodwill and Intangible Assets: Goodwill represents the cost in excess of the fair value of net assets acquired (including identifiable intangibles) in transactions accounted for as business combinations. Goodwill has an indefinite useful life and is evaluated for impairment annually, or more frequently if events and circumstances indicate that the asset might be impaired. Other acquired intangible assets with finite lives, such as core deposit intangibles and customer list intangibles, are initially recorded at fair value and amortized over their estimated useful lives. Intangible assets are evaluated for impairment when events or changes in circumstances indicate a potential impairment. ​ Transfers of Financial Assets: Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company - put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. ​ Bank Owned Life Insurance: The Company has purchased life insurance policies on certain key employees. The purchase of these life insurance policies allows the Company to use tax-advantaged rates of return. Bank-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. ​ Derivative Instruments: The Company applies hedge accounting to certain interest rate derivatives entered into for risk management purposes. In accordance with ASC Topic 815, Derivatives and Hedging, all derivative instruments are recorded on the accompanying consolidated balance sheet at their respective fair values. The accounting for changes in fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship. If the derivative instrument is not designated as a hedge, changes in the fair value of the derivative instrument are recognized in earnings in the period of change. The Company enters into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financial needs. Upon entering into these instruments to meet customer needs, the Company enters into offsetting positions with large U.S. financial institutions in order to minimize the risk to the Company. These swaps are derivatives, but are not designated as hedging instruments. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. ​ Leases The Company leases certain branch locations, administrative offices and equipment. Operating lease Right of Use (“ROU”) assets are included in other assets and the associated lease obligations are included in other liabilities. Leases with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets; the Company instead recognizes lease expense for these leases on a straight-line basis over the lease term. ​ ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s corresponding obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate is determined using secured rates for new FHLB advances under similar terms as the lease at inception. The Company utilizes the implicit or incremental borrowing rate at the effective date of a modification not accounted for as a separate contract or a change in the lease terms to determine the present value of lease payments. For operating leases commencing prior to January 1, 2019, the Company used the incremental borrowing rate as of that date. ​ Most leases include one or more options to renew, with renewal terms that can extend the lease term. The exercise of lease renewal options is at the Company’s sole discretion. When it is reasonably certain the Company will exercise its option to renew or extend the lease term, the option is included in calculating the value of the ROU asset and lease liability. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. ​ ​ Revenue Recognition Service charges on deposit accounts Investment services Insurance commissions Interchange and debit card transaction fees, net Other ​ Advertising Costs: The Company expenses all advertising and marketing costs as incurred. ​ Income Taxes: The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. Deferred tax assets may be reduced by deferred tax liabilities and a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. ​ Stock-Based Compensation Plans: The Company has stock options, restricted stock awards and stock appreciation rights under stock-based compensation plans, which are described in more detail in Note 13-Employee Benefits. The plans have been accounted for under the accounting guidance (FASB ASC 718, Compensation Stock Compensation) The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees’ service period, generally defined as the vesting period. For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. A Black-Scholes model is used to estimate the fair value of stock options, while the market value of the Company’s common stock at the date of grant is used for restrictive stock awards and stock grants. Comprehensive Income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, primarily, (1) unrealized gains and losses on available-for-sale securities and (2) unrealized gains and losses on effective portions of fair value security hedges, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income. ​ Business Combinations: Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method of accounting, acquired assets and assumed liabilities are included with the acquirer’s accounts as of the date of acquisition at estimated fair value, with any excess of purchase price over the fair value of the net assets acquired (including identifiable intangible assets) capitalized as goodwill. In the event that the fair value of the net assets acquired exceeds the purchase price, an acquisition gain is recorded for the difference in consolidated statements of income for the period in which the acquisition occurred. An intangible asset is recognized as an asset apart from goodwill when it arises from contractual or other legal rights or if it is capable of being separated or divided from the acquired entity and sold, transferred, licensed, rented or exchanged. In addition, acquisition-related costs and restructuring costs are recognized as period expenses as incurred. Estimates of fair value are subject to refinement for a period not to exceed one year from acquisition date as information relative to acquisition date fair values becomes available. ​ Earnings Per Common Share: Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding and dilutive common share equivalents using the treasury stock method. Dilutive common share equivalents include common shares issuable upon exercise of outstanding stock options and restricted stock. ​ Operating Segments: The Company’s chief operating decision maker primarily manages operations and assesses financial performance on a Company-wide basis. However, in addition to the discrete financial information that is provided for the Company as a whole, financial information is also provided for the wealth management services, insurance services and mortgage origination segments, respectively. While the chief operating decision maker uses the financial information related to these segments to analyze business performance and allocate resources, these segments do not meet the quantitative threshold under GAAP to be considered a reportable segment. As such, these operating segments, along with the banking operations segment, are aggregated into a single reportable operating ​ Recently Issued Not Yet Effective Accounting Pronouncements: The following is a summary of recent authoritative pronouncements not yet in effect that could impact the accounting, reporting, and/or disclosure of financial information by the Company. In October 2019, the Financial Accounting Standards Board approved a delay for the implementation of ASU 2016-13, Financial Instruments - Credit Losses Under the CECL model, we will be required to present certain financial assets carried at amortized cost, such as loans held for investment and held-to-maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the “incurred loss” model currently required under GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, we expect that the adoption of the CECL model will materially affect how we determine our allowance for loan losses and could require us to significantly increase our allowance. Moreover, the CECL model may create more volatility in the level of our allowance for loan losses. If we are required to materially increase our level of allowance for loan losses for any reason, such increase could adversely affect our business, financial condition and results of operations. ​ A cross-functional working group comprised of individuals from credit administration, risk management and accounting and finance are in place implementing and developing the data, forecast, processes, and portfolio segmentation that will be used in the models that will estimate the expected credit loss for each loan segment. The Company has contracted with a third party vendor solution to assist us in the application, analysis, and model development required with implementation of ASU 2016-13. The Company is currently unable to reasonably estimate the impact of adopting ASU 2016-13, and it will be influenced by the composition, characteristics and quality of our loan and securities portfolio, as well as the economic conditions and forecasts as of each reporting period. These economic conditions and forecasts could be sig

Following the closing of the acquisition, on May 4, 2021, the Company changed the name of Fountain Leasing, LLC to Fountain Equipment Finance, LLC (“Fountain”). In connection with the acquisition, the Company acquired $54.1 million of assets and assumed $683 thousand of liabilities. Pursuant to the Purchase Agreement, the Company paid an aggregate amount of consideration to the Fountain members of $14.0 million in cash at closing, and the Company repaid approximately $45.8 million of Fountain’s indebtedness.

On March 1, 2020, the Company completed the merger of Progressive Financial Group, Inc., a Tennessee corporation (“PFG”), pursuant to an Agreement and Plan of Merger dated October 29, 2019 (the “Merger Agreement”). In connection with the merger, the Company acquired $301 million of assets and assumed $272 million of liabilities. Pursuant to the Merger Agreement, each outstanding share of PFG common stock was converted into and cancelled in exchange to the right to receive $474.82 in cash, and 62.3808 shares of the Company’s common stock. The Company issued 1,292,578 shares of its common stock and paid $9.8 million in cash as consideration for the Merger. The fair value of consideration paid exceeded the fair value of the identifiable assets and liabilities acquired and resulted in the establishment of goodwill in the amount of $8.8 million, representing the intangible value of PFG’s business and reputation within the markets it served. None of the goodwill recognized is expected to be deductible for income tax purposes. The Company is amortizing the related core deposit intangible of $1.4 million using the effective yield method over 120 months (10 years), which represents the expected useful life of the asset. The Company also established two intangible assets related to the insurance agency acquired as part of the PFG acquisition; 1.) Customer relationships of $1.1 million, amortizing sum-of-the-years digits over 120 months (10 years), 2.) Tradename of $63 thousand, amortizing straight-line over 60 months (5 years).

During the fourth quarter of 2021, the Company transferred $74.6 million of available-for-sale debt securities to the held-to-maturity category, reflecting the Company’s intent to hold those securities to maturity. Transfers of investment securities into the held-to-maturity category from the available-for-sale category are made at fair value at the date of transfer. The related $905 thousand of unrealized holding gain that was included in the transfer is retained in accumulated other comprehensive income and in the carrying value of the held-to-maturity securities. This amount will be amortized as an adjustment to interest income over the remaining life of the securities. This will offset the impact of amortization of the net premium created in the transfer. There were no gains or losses recognized as a result of this transfer. ​ The Company has entered into various fair value hedging transactions to mitigate the impact of changing interest rates on the fair values of available for sale securities.

A determination as to whether a security’s decline in fair value is other-than-temporary takes into consideration numerous factors and the relative significance of any single factor can vary by security. Some factors the Company may consider in the other-than-temporary impairment analysis include the length of time and extent to which the security has been in an unrealized loss position, changes in security ratings, financial condition and near-term prospects of the issuer, as well as security and industry specific economic conditions. Based on this evaluation, the Company concluded that any unrealized losses at December 31, 2021 represented a temporary impairment, as these unrealized losses are primarily attributable to changes in interest rates and current market conditions, and not credit deterioration of the issuers. As of December 31, 2021, the Company does not intend to sell any of the securities, does not expect to be required to sell any of the securities, and expects to recover the entire amortized cost of all of the securities. Other Investments: Our other investments consist of restricted non-marketable equity securities that have no readily determinable market value. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value. As of December 31, 2021, the Company determined that there was no impairment on its other investment securities.

A portfolio segment is defined as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. There are six loan and lease portfolio segments that include commercial real estate, consumer real estate, construction and land development, commercial and industrial, leases, and consumer and other. The following describe risk characteristics relevant to each of the portfolio segments: Commercial Real Estate: Consumer Real Estate: Construction and Land Development: Commercial and Industrial: Leases: ​ Consumer and Other: Credit Risk Management: The Company employs a credit risk management process with defined policies, accountability and routine reporting to manage credit risk in the loan and lease portfolio segments. Credit risk management is guided by credit policies that provide for a consistent and prudent approach to underwriting and approvals of credits. Within the Credit Policy, procedures exist that elevate the approval requirements as credits become larger and more complex. All loans and leases are individually underwritten, risk-rated, approved, and monitored. Responsibility and accountability for adherence to underwriting policies and accurate risk ratings lies in each portfolio segment. For the consumer real estate and consumer and other portfolio segments, the risk management process focuses on managing customers who become delinquent in their payments. For the other portfolio segments, the risk management process focuses on underwriting new business and, on an ongoing basis, monitoring the credit of the portfolios, including a third party review of the largest credits on an annual basis or more frequently, as needed. To ensure problem credits are identified on a timely basis, several specific portfolio reviews occur periodically to assess the larger adversely rated credits for proper risk rating and accrual status. Credit quality and trends in the loan and lease portfolio segments are measured and monitored regularly. Detailed reports, by product, collateral, accrual status, etc., are reviewed by Director, Management and Loan Committees. The allowance for loan and lease losses is a valuation reserve established through provisions for loan and lease losses charged against income. The allowance for loan and lease losses, which is evaluated quarterly, is maintained at a level that management deems sufficient to absorb probable losses inherent in the loan and lease portfolio. Loans and leases deemed to be uncollectible are charged against the allowance for loan and lease losses, while recoveries of previously charged-off amounts are credited to the allowance for loan and lease losses. The allowance for loan and lease losses is comprised of specific valuation allowances for loans and leases evaluated individually for impairment and general allocations for pools of homogeneous loans and leases with similar risk characteristics and trends. The allowance for loan and lease losses related to specific loans and leases is based on management’s estimate of potential losses on impaired loans and leases as determined by (1) the present value of expected future cash flows; (2) the fair value of collateral if the loan or lease is determined to be collateral dependent or (3) the loan’s or leases’ observable market price. The Company’s homogeneous loan and lease pools include commercial real estate loans, consumer real estate loans, construction and land development loans, commercial and industrial loans, leases and consumer and other loans. The general allocations to these loan and lease pools are based on the historical loss rates for specific loan and lease types and the internal risk grade, if applicable, adjusted for both internal and external qualitative risk factors. The qualitative factors considered by management include, among other factors, (1) changes in local and national economic conditions; (2) changes in asset quality; (3) changes in loan and lease portfolio volume; (4) the composition and concentrations of credit; (5) the impact of competition on loan and lease structuring and pricing; (6) the impact of the regulatory environment and changes in laws; (7) effectiveness of the Company’s loan and lease policies, procedures and internal controls; (8) COVID-19 loan modification factor and (9) COVID-19 Q factor, which is based upon active COVID cases within the Company’s footprint. The total allowance established for each homogeneous loan and lease pool represents the product of the historical loss ratio adjusted for qualitative factors and the total dollar amount of the loans and leases in the pool. The determination of the adequacy of the allowance for loan and lease losses is based on estimates that are particularly susceptible to significant changes in the economic environment and market conditions. In connection with the determination of the estimated losses on loans and leases, management obtains independent appraisals for significant collateral. The Company’s loans and leases are generally secured by specific items of collateral including real property, consumer assets, and business assets. Although the Company has a diversified loan and lease portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent on local economic conditions. While management uses available information to recognize losses on loans and leases, further reductions in the carrying amounts of loans and leases may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans and leases. Such agencies may require the Company to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans and leases may change materially in the near term.

Restructurings: At December 31, 2021 and 2020, impaired loans included loans that were classified as TDRs. The restructuring of a loan is considered a TDR if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession. In assessing whether or not a borrower is experiencing financial difficulties, the Company considers information currently available regarding the financial condition of the borrower. This information includes, but is not limited to, whether (i) the debtor is currently in payment default on any of its debt; (ii) a payment default is probable in the foreseeable future without the modification; (iii) the debtor has declared or is in the process of declaring bankruptcy; and (iv) the debtor’s projected cash flow is sufficient to satisfy contractual payments due under the original terms of the loan without a modification. The Company considers all aspects of the modification to loan terms to determine whether or not a concession has been granted to the borrower. Key factors considered by the Company include the debtor’s ability to access funds at a market rate for debt with similar risk characteristics, the significance of the modification relative to unpaid principal balance or collateral value of the debt, and the significance of a delay in the timing of payments relative to the original contractual terms of the loan. The most common concessions granted by the Company generally include one or more modifications to the terms of the debt, such as (i) a reduction in the interest rate for the remaining life of the debt; (ii) an extension of the maturity date at an interest rate lower than the current market rate for new debt with similar risk; (iii) a temporary period of interest-only payments; and (iv) a reduction in the contractual payment amount for either a short period or remaining term of the loan. As of December 31, 2021, and 2020, management had approximately $206 thousand and $257 thousand, respectively, in loans that met the criteria for TDR restructured loans, none of which were on nonaccrual. A loan is placed back on accrual status when both principal and interest are current and it is probable that management will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement. The following table presents a summary of loans that were modified as troubled debt restructurings at December 31, 2021 (dollars in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Pre-Modification Post-Modification ​ ​ ​ Outstanding Outstanding ​ ​ ​ Recorded Recorded December 31, 2021 ​ Number of Contracts Investment Investment Consumer real estate ​ 1 ​ $ 104 ​ $ 104 Commercial and industrial ​ 2 ​ ​ 96 ​ ​ 96 Consumer and other ​ 1 ​ ​ 6 ​ ​ 6 ​ ​ ​ ​ ​ ​ ​ ​ ​ There were no loans that were modified as troubled debt restructurings during the past twelve months. The two commercial and industrial loans and the one consumer and other loan are currently past due. The Company began offering short-term loan modifications to assist borrowers during the COVID-19 national emergency. The Coronavirus Aid Relief and Economic Security (“CARES”) Act along with a joint agency statement issued by banking agencies, provides that short-term modifications made in response to COVID-19 does not need to be accounted for as a TDR. Accordingly, the Company does not account for such loan modifications as TDRs. See Note 1 Presentation of Financial Information Foreclosure Proceedings and Balances : As of December 31, 2021, the were no residential real estate properties where physical possession had been obtained and included with in other real estate owned assets and one property for $26 thousand at December 31, 2020.

Unamortized debt issuance cost was $570 thousand and $654 thousand at December 31, 2021 and 2020, respectively. The Notes initially bears interest at a rate of 5.625% per annum from and including September 28, 2018, to but excluding October 2, 2023, with interest during this period payable semi-annually in arrears. From and including October 2, 2023, to but excluding the maturity date or early redemption date, the interest rate will reset quarterly to an annual floating rate equal to three-month LIBOR, or an alternative rate determined in accordance with the terms of the Notes if three-month LIBOR cannot be determined, plus 255 basis points, with interest during this period payable quarterly in arrears. The Notes are redeemable by the Company, in whole or in part, on or after October 2, 2023, and at any time, in whole but not in part, upon the occurrence of certain events. The Notes have been structured to qualify initially as Tier 2 capital for the Company for regulatory capital purposes. The Notes debt issuance costs totaled $844 thousand and will be amortized through the Notes’ maturity date. Amortization expense totaled $84 thousand and $84 thousand for the years ended December 31, 2021 and 2020, respectively. On September 1, 2021, the Company acquired $2.5 million of subordinated notes (“sub-debt”) from the acquisition of SCB.

Leases [Abstract]
Leases	Note 11. Leases A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On January 1, 2019, the Company adopted ASU No. 2016-02 and all subsequent ASUs that modified this topic (collectively referred to as "Topic 842"). For the Company, Topic 842 primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee. Substantially all of the leases in which the Company is the lessee are comprised of real estate for branches and office space with terms extending through 2034. All of our leases are classified as operating leases, and therefore, were previously not recognized on the Company’s consolidated balance sheet. With the adoption of Topic 842, operating lease agreements are required to be recognized on the consolidated balance sheet as a right-of-use (“ROU”) asset and a corresponding lease liability. The following table represents the consolidated balance sheet classification of the Company’s ROU assets and lease liabilities. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), or equipment leases (deemed immaterial) on the consolidated balance sheet (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, ​ ​ Classification ​ 2021 ​ 2020 Assets: ​ ​ ​ Operating lease right-of-use assets Other assets ​ $ 9,812 ​ $ 4,797 Liabilities: ​ ​ ​ Operating lease liabilities Other liabilities ​ $ 9,881 ​ $ 4,827 ​ The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew As of December 31, 2021, the weighted average remaining lease term was 9.91 years and the weighted average discount rate was 2.08%. The Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance. The following table represents lease costs and other lease information for the years ended December 31, (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 Lease costs: ​ ​ ​ ​ Operating lease costs ​ $ 1,222 ​ $ 1,044 Variable lease costs ​ 97 ​ 111 Total ​ $ 1,319 ​ $ 1,155 Other information: ​ ​ Cash paid for amounts included in the measurement of lease liabilities: ​ ​ Operating cash flows from operating leases ​ $ 1,180 ​ $ 1,265 ​ Future minimum payments for operating leases with initial or remaining terms of one year or more as of December 31, 2021 were as follows (in thousands) ​ ​ ​ ​ ​ Amounts 2022 $ 1,522 2023 ​ 1,272 2024 ​ 1,061 2025 ​ 1,044 2026 ​ 946 Thereafter ​ 5,250 Total future minimum lease payments ​ 11,095 Amounts representing interest ​ (1,214) Present value of net future minimum lease payments ​ $ 9,881 ​ Lease expense for the years ended December 31, 2021 and 2020, was $1.3 million and $1.2 million, respectively. The Company entered into two leasing arrangements for branch offices with companies that are wholly owned by a board of director’s immediate family. The Company has determined that these leasing arrangements were considered economically fair and in the best interest of the Company. For the years ended December 31, 2021 and 2020, the Company paid $150 thousand for each period, respectively, for base rent payments.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 14. Commitments and Contingent Liabilities Commitments: The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing and depository needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amount recognized in the balance sheets. The majority of all commitments to extend credit are variable rate instruments while the standby letters of credit are primarily fixed rate instruments. The Company’s exposure to credit loss is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments as it does for on-balance sheet instruments. A summary of the Company's total contractual amount for all off-balance sheet commitments for the years ended December 31, 2021 and 2020, are as follows (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ 2021 ​ 2020 Commitments to extend credit $ 669,770 ​ $ 476,841 Standby letters of credit ​ 17,868 ​ 5,261 ​ 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. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customer. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate, and income-producing commercial properties. Standby letters of credit issued by the Company are conditional commitments to guarantee the performance of a customer to a third party. Those letters of credit are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Collateral held varies and is required in instances which the Company deems necessary. At December 31, 2021 and 2020, the carrying amount of liabilities related to the Company’s obligation to perform under standby letters of credit was insignificant. The Company has not been required to perform on any standby letters of credit, and the Company has not incurred any losses on standby letters of credit for the years ended December 31, 2021 and 2020. Contingent Liabilities: The Company is subject in the normal course of business to various pending and threatened legal proceedings in which claims for monetary damages are asserted. Management, after consultation with legal counsel, does not anticipate that the aggregate ultimate liability arising out of litigation pending or threatened against the Company will be material to the Company’s consolidated financial position. On an on-going basis, the Company assesses any potential liabilities or contingencies in connection with such legal proceedings. For those matters where it is deemed probable that the Company will incur losses and the amount of the losses can be reasonably estimated, the Company would record an expense and corresponding liability in its consolidated financial statements.

Regulatory Matters

Regulatory Matters	12 Months Ended

Banking and Thrift [Abstract]
Regulatory Matters	Note 15. Regulatory Matters Regulatory Capital Requirements: The final rules implementing the Basel Committee on Banking Supervision's capital guidelines for U.S. banks (Basel III rules) became effective January 1, 2015. In order to avoid restrictions on capital distributions and discretionary bonus payments to executives, under the new rules a covered banking organization is also required to maintain a “capital conservation buffer” in addition to its minimum risk-based capital requirements. This buffer is required to consist solely of common equity Tier 1, and the buffer applies to all three risk-based measurements (CET1, Tier 1 capital and total capital). As of January 1, 2019, an additional amount of Tier 1 common equity equal to 2.5% of risk-weighted assets is required for compliance with the capital conservation buffer. The ratios for the Company and the Bank are currently sufficient to satisfy the fully phased-in conservation buffer. At December 31, 2021, the Company and the Bank exceeded the minimum regulatory requirements and exceeded the threshold for the "well capitalized" regulatory classification. ​ Regulatory Restrictions on Dividends: Pursuant to Tennessee banking law, the Bank may not, without the prior consent of the Commissioner of the Tennessee Department of Financial Institutions (the “TDFI”), pay any dividends to the Company in a calendar year in excess of the total of the Bank’s retained net income for that year plus the retained net income for the preceding two years. Because this test involves a measure of net income, any charge on the Bank’s income statement, such as an impairment of goodwill, could impair the Bank’s ability to pay dividends to the Company. Under Tennessee corporate law, the Company is not permitted to pay dividends if, after giving effect to such payment, it would not be able to pay its debts as they become due in the usual course of business or its total assets would be less than the sum of its total liabilities plus any amounts needed to satisfy any preferential rights if it were dissolving. In addition, in deciding whether or not to declare a dividend of any particular size, the Company’s board of directors must consider its and the Bank’s current and prospective capital, liquidity, and other needs. In addition to state law limitations on the Company’s ability to pay dividends, the Federal Reserve imposes limitations on the Company’s ability to pay dividends. Federal Reserve regulations limit dividends, stock repurchases and discretionary bonuses to executive officers if the Company’s regulatory capital is below the level of regulatory minimums plus the applicable capital conservation buffer. During the years ended December 31, 2021, and 2020, the Bank paid $10.0 million and $13.9 million, respectively, in dividends to the Company. Since the fourth quarter of 2019, the Company has paid a quarterly common stock dividend. During the years ended December 31, 2021, and 2020, the Company paid a quarterly common stock dividend of $0.06 and $0.05 per share, respectively. The amount and timing of all future dividend payments by the Company, if any, is subject to discretion of the Company’s board of directors and will depend on the Company’s earnings, capital position, financial condition and other factors, including new regulatory capital requirements, as they become known to the Company.

Risks and Uncertainties [Abstract]
Concentrations of Credit Risk	Note 16. Concentrations of Credit Risk The Company originates primarily commercial, residential, and consumer loans to customers in East and Middle Tennessee, Alabama, and the Florida panhandle. The ability of the majority of the Company’s customers to honor their contractual loan obligations is dependent on the economy in these areas. Seventy-nine percent of the Company’s loan portfolio is concentrated in loans secured by real estate, of which a substantial portion is secured by real estate in the Company’s primary market areas. Commercial real estate, including commercial construction loans, represented 59% of the loan portfolio at December 31, 2021, and 51% of the loan portfolio at December 31, 2020. Accordingly, the ultimate collectability of the loan portfolio and recovery of the carrying amount of other real estate owned is susceptible to changes in real estate conditions in the Company’s primary market areas. The other concentrations of credit by type of loan are set forth in Note 5. The Bank, as a matter of policy, does not generally extend credit to any single borrower or group of related borrowers in excess of 25% of statutory capital, or approximately $115.3 million.

Fair Value of Assets and Liabilities [Abstract]
Fair Value of Assets and Liabilities	Note 17. Fair Value of Assets and Liabilities Determination of Fair Value: The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the “Fair Value Measurements and Disclosures” ASC Topic 820, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. ASC Topic 820 provides a consistent definition of fair value, which focuses on exit price in an orderly transaction between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact business at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. Fair Value Hierarchy: In accordance with this guidance, the Company groups its financial assets and financial liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 Level 2 - Level 3 - A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following methodologies were used by the Company in estimating fair value disclosures for financial instruments: Securities available-for-sale: party provider evaluates securities based on comparable investments with trades and market data and will utilize pricing models that use a variety of inputs, such as benchmark yields, reported trades, broker-dealer quotes, issuer spreads, benchmark securities, bids and offers as needed. These securities are generally classified as Level 2.

These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include deferred income taxes and premises and equipment. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives Financial Instruments	Note 18. Derivatives Financial Instruments Derivatives designated as fair value hedges: Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative net investment hedge instrument as well as the offsetting gain or loss on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. The Company utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate tax-exempt callable securities available-for-sale. The hedging strategy on securities converts the fixed interest rates to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities. The Company has elected early adoption of ASU 2017-12, Derivatives and Hedging (Topic 815) - Targeted Improvements to Accounting for Hedging Activities A summary of the Company’s fair value hedge relationships for the periods presented are as follows (dollars in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ ​ ​ ​ Average ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance ​ Remaining ​ Weighted ​ ​ ​ ​ ​ ​ ​ ​ ​ Sheet ​ Maturity ​ Average ​ Receive ​ Notional ​ Estimated Liability derivatives ​ Location ​ (In Years) ​ Pay Rate ​ Rate ​ Amount ​ Fair Value December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swap agreements - securities Other liabilities 6.20 3.09 % 3 month LIBOR ​ $ 36,000 $ (3,567) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Interest rate swap agreements - securities Other liabilities 7.13 3.08 % 3 month LIBOR ​ $ 36,000 ​ $ (6,174) ​ ​ The effects of the Company’s fair value hedge relationships reported in interest income on tax-exempt available-for-sale securities on the consolidated income statement were as follows (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, ​ ​ 2021 ​ 2020 Interest income on tax-exempt securities ​ $ 2,205 ​ $ 2,150 Effects of fair value hedge relationships ​ (1,050) ​ (781) Reported interest income on tax-exempt securities ​ $ 1,155 ​ $ 1,369 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ December 31, Gain (loss) on fair value hedging relationship ​ 2021 ​ 2020 Interest rate swap agreements - securities: ​ ​ ​ Hedged items ​ $ (3,567) ​ $ (6,174) Derivative designated as hedging instruments ​ $ 3,567 ​ $ 6,174 Carry amount of hedged assets - securities available for sale ​ $ 43,119 ​ $ 44,017 ​ ​ Non-hedged derivatives: ​ During the second quarter of 2021, the Company initiated a loan hedging program to certain loan customers. Through this program, the Company originates a variable rate loan with the customer. The Company and the customer will then enter into a fixed interest rate swap. Lastly, an identical offsetting swap is entered into by the Company with a dealer bank. These “back-to-back” swap arrangements are intended to offset each other and allow the Company to book a variable rate loan, while providing the customer with a contract for fixed interest payments. In these arrangements, the Company’s net cash flow is equal to the interest income received from the variable rate loan originated with the customer. These customer swaps are not designated as hedging ​ At December 31, 2021, and 2020, respectively, interest rate swaps related to the Company’s loan hedging program that were outstanding are presented in the following table (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2021 ​ December 31, 2020 ​ ​ ​ Notional ​ ​ Estimated ​ ​ Notional ​ ​ Estimated ​ ​ ​ Amount ​ ​ Fair Value ​ ​ Amount ​ ​ Fair Value Interest rate swap agreements: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets ​ $ 48,125 ​ $ 1,326 ​ $ - ​ $ - Liabilities ​ ​ 48,125 ​ ​ (1,326) ​ ​ - ​ ​ - ​ ​ ​ ​ ​ ​ ​ The Company establishes limits and monitors exposures for customer swap positions.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Nature of Business	Nature of Business: SmartFinancial, Inc. (the "Company") is a bank holding company whose principal activity is the ownership and management of its wholly-owned subsidiary, SmartBank (the "Bank"). The Company provides a variety of financial services to individuals and corporate customers through its offices in East and Middle Tennessee, Alabama and Florida panhandle. The Company’s primary deposit products are interest-bearing demand deposits, savings and money market deposits, and time deposits. Its primary lending products are commercial, residential, and consumer loans.
Basis of Presentation	Basis of Presentation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation.
Accounting Estimates	Accounting Estimates: In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet, and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, the valuation of other real estate owned, deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and business combination elements (Day 1 and Day 2 Valuation). ​
Cash and Cash Equivalents	Cash and Cash Equivalents: For purposes of reporting consolidated cash flows, cash and due from banks includes cash on hand, cash items in process of collection and amounts due from banks. Cash and cash equivalents also includes interest-bearing deposits in banks and federal funds sold. Cash flows from loans, federal funds sold, securities sold under agreements to repurchase and deposits are reported net. The in cash or on deposit Bank is required to maintain average balances with the Federal Reserve Bank. During 2020 the Federal Reserve Bank suspended reserve requirements to provide relief related to the COVID-19 pandemic, thus the Bank did not have a reserve requirement at December 31, 2021 and 2020, respectively.
Securities	Securities: Securities are classified based on management’s intention on the date of purchase. All debt securities classified as available-for-sale are recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Securities that the Company has both the positive intent and ability to hold to maturity are classified as held-to-maturity and are carried at historical cost and adjusted for amortization of premiums and accretion of discounts. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Transfers of investments securities into the held-to-maturity category from the available-for-sale category are made at fair value at the date of transfer. The unrealized holdings gain or loss at the date of transfer is retained in accumulated other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts are amortized over the remaining life of the security. The Company evaluates securities quarterly for other than temporary impairment using relevant accounting guidance specifying that (a) if the Company does not have the intent to sell a debt security prior to recovery and (b) it is more likely than not that it will not have to sell the debt security prior to recovery, the security would not be considered other than temporarily impaired unless a credit loss has occurred in the security. If management does not intend to sell the security and it is more likely than not that they will not have to sell the security before recovery of the cost basis, management will recognize the credit component of an other-than- temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income. Securities borrowed or purchased under agreements to resell and securities loaned or sold under agreements to repurchase are treated as collateralized financial transactions. These agreements are recorded at the amount at which the securities were acquired or sold plus accrued interest. It is the Company’s policy to take possession of securities purchased under resale agreements. The market value of these securities is monitored, and additional securities are obtained when deemed appropriate to ensure such transactions are adequately collateralized. The Company also monitors its exposure with respect to securities sold under repurchase agreements, and a request for the return of excess securities held by the counterparty is made when deemed appropriate.
Other Investments	Other Investments: The Company is required to maintain an investment in capital stock of various entities, including the Federal Home Loan Bank and Federal Reserve Bank. Based on redemption provisions of these entities, the stock has no quoted market value and is carried at cost. At their discretion, these entities may declare dividends on the stock. Management reviews restricted investments for impairment based on the ultimate recoverability of the cost basis in these stocks.
Loans Held for Sale	Loans Held for Sale: Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or estimated fair value. Gains and losses on sales of loans held for sale are included in the Consolidated Statements of Income in mortgage banking. Loans held for sale are sold to investors with best effort intent and ability to sell loans as long as they meet the underwriting standards of the potential investor.
Loans and Leases	Loans and Leases: Originated loans and leases for which management has the intent and ability to hold for the foreseeable future or until maturity or payoff are carried at the principal amount outstanding net of any unearned income, charge-offs and unamortized fees and costs. Nonrefundable fees collected and certain direct costs incurred related to loan and lease originations are deferred and recorded as an adjustment to loans and leases outstanding. The net amount of the nonrefundable fees and costs is amortized to interest income over the contractual lives using methods that approximate a constant yield. ​ The accrual of interest on loans and leases is discontinued when, in management’s opinion, the borrower may be unable to meet the contractual terms of the obligation payments as they become due, or at the time the loan or lease is 90 days past due, unless the loan is well-secured and in the process of collection. Unsecured loans and leases are typically charged off no later than 120 days past due. Past due status is based on contractual terms of the loan or lease. In all cases, loans and leases are placed on nonaccrual or charged-off at an earlier date if collection of principal and interest is considered doubtful. All interest accrued but not collected for loans and leases that are placed on nonaccrual or charged off is reversed against interest income, unless management believes that the accrual of interest is recoverable through the liquidation of collateral. Interest income on nonaccrual loans and leases is recognized on the cash basis, until the loans or leases are returned to accrual status. Loans and leases are returned to accrual status when all the principal and interest amounts contractually due are brought current and the loan or lease has been performing according to the contractual terms for a period of not less than six months.
Acquired Loans	Acquired Loans: Acquired loans and leases are those acquired in business combinations by the Company or Bank. The fair values of acquired loans and leases with evidence of credit deterioration, Purchased Credit Impaired loans and leases (“PCI loans and leases”), are recorded net of a nonaccretable discount and accretable discount. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable discount and is recognized in interest income over the remaining life of the loan or lease when there is reasonable expectation about the amount and timing of such cash flows. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is the nonaccretable discount, which is included in the carrying amount of acquired loans and leases. Subsequent decreases to the expected cash flows will generally result in a provision for loan and lease losses. Subsequent significant increases in cash flows result in a reversal of the provision for loan and lease losses to the extent of prior charges or a reclassification of the difference from nonaccretable to accretable with a positive impact on the accretable discount. Acquired loans and leases are initially recorded at fair value at acquisition date. Accretable discounts related to certain fair value adjustments are accreted into income over the estimated lives of the loans or leases. The Company accounts for PCI loans and leases acquired in the acquisition using the expected cash flows method of recognizing discount accretion based on the acquired loans and leases expected cash flows. Management recasts the estimate of cash flows expected to be collected on each acquired impaired loan and lease pool periodically. If the present value of expected cash flows for a pool is less than its carrying value, an impairment is recognized by an increase in the allowance for loan and lease losses and a charge to the provision for loan and lease losses. If the present value of expected cash flows for a pool is greater than its carrying value, any previously established allowance for loan and lease losses is reversed and any remaining difference increases the accretable yield which will be taken into interest income over the remaining life of the loan or lease pool. Purchased performing loans and leases are recorded at fair value, including a credit discount or premium. Credit losses on acquired performing loans and leases are estimated based on analysis of the performing portfolio at the time of purchase. Such estimated credit losses are recorded as nonaccretable discounts in a manner similar to purchased impaired loans and leases. The fair value discount other than for credit loss is accreted as an adjustment to yield over the estimated lives of the loans and leases. A provision for loan and lease losses is recorded for any deterioration in these loans or leases subsequent to the acquisition.
Allowance for Loan Losses and Lease Losses	Allowance for Loan and Lease Losses: The allowance for loan and lease losses is established as losses are estimated to have occurred through a provision for loan and lease losses charged to expense. Loan and lease losses are charged against the allowance when management believes the uncollectibility of a loan or lease balance is confirmed. Confirmed losses are charged off immediately. Subsequent recoveries, if any, are credited to the allowance. The allowance is an amount that management believes will be adequate to absorb estimated losses relating to specifically identified loans and leases, as well as probable credit losses inherent in the balance of the loan and lease portfolio. The allowance for loan and lease losses is evaluated on a regular basis by management and is based upon management’s periodic review of the uncollectibility of loans and leases in light of historical experience, the nature and volume of the loan and lease portfolio, overall portfolio quality, review of specific problem loans or leases, current economic conditions that may affect the borrower’s ability to pay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. This evaluation does not include the effects of expected losses on specific loans or leases or groups of loans or leases that are related to future events or expected changes in economic conditions. The allowance consists of specific and general components. The specific component relates to loans and leases that are classified as impaired. For impaired loans and leases, an allowance is established when the discounted cash flows, collateral value, or observable market price of the impaired loan or lease is lower than the carrying value of that loan or lease. The general component covers non-impaired loans and leases and is based on the Company’s historical loss experience adjusted for other qualitative factors. Other adjustments may be made to the allowance for pools of loans and leases after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. An unallocated component may be maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. As part of the risk management program, an independent review is performed on the loan and lease portfolio according to policy, which supplements management’s assessment of the loan and lease portfolio and the allowance for loan or lease losses. The result of the independent review is reported directly to the Audit Committee of the Board of Directors. Loans and leases, for which the terms have been modified at the borrower’s request, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. A loan or lease is considered impaired when it is probable, based on current information and events, the Company will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan or lease agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest when due. Loans and leases that experience insignificant payment delays and payment shortfalls are not classified as impaired. Impaired loans and leases are measured by either the present value of expected future cash flows discounted at the loans or leases effective interest rate, the loans or leases obtainable market price, or the fair value of the collateral if the loan or lease is collateral dependent. Interest on accruing impaired loans or leases is recognized as long as such loans or leases do not meet the criteria for nonaccrual status. Large groups of smaller balance homogeneous loans and leases are collectively evaluated for impairment. The Company’s homogeneous loan and lease pools include consumer real estate loans, commercial real estate loans, construction and land development loans, commercial and industrial loans, leases and consumer and other loans. The general allocations to these loan and lease pools are based on the historical loss rates for specific loan and lease types and the internal risk grade, if applicable, adjusted for both internal and external qualitative risk factors.
Troubled Debt Restructurings	Troubled Debt Restructurings: The Company designates loan modifications as Troubled Debt Restructurings ("TDRs") when for economic and legal reasons related to the borrower’s financial difficulties, it grants a concession to the borrower that it would not otherwise consider. TDRs can involve loans remaining on nonaccrual, moving to nonaccrual, or continuing on accrual status, depending on the individual facts and circumstances of the borrower. In circumstances where the TDR involves charging off a portion of the loan balance, the Company typically classifies these restructurings as nonaccrual. In connection with restructurings, the decision to maintain a loan that has been restructured on accrual status is based on a current, well documented credit evaluation of the borrower’s financial condition and prospects for repayment under the modified terms. This evaluation includes consideration of the borrower’s current capacity to pay, which among other things may include a review of the borrower’s current financial statements, an analysis of global cash flow sufficient to pay all debt obligations, a debt to income analysis, and an evaluation of secondary sources of payment from the borrower and any guarantors. This evaluation also includes an evaluation of the borrower’s current willingness to pay, which may include a review of past payment history, an evaluation of the borrower’s willingness to provide information on a timely basis, and consideration of offers from the borrower to provide additional collateral or guarantor support. The credit evaluation also reflects consideration of the borrower’s future capacity and willingness to pay, which may include evaluation of cash flow projections, consideration of the adequacy of collateral to cover all principal and interest, and trends indicating improving profitability and collectability of receivables. Restructured nonaccrual loans may be returned to accrual status based on a current, well-documented credit evaluation of the borrower’s financial condition and prospects for repayment under the modified terms. This evaluation must include consideration of the borrower’s sustained historical repayment for a reasonable period, generally a minimum of six months, prior to the date on which the loan is returned to accrual status.
Other Real Estate Owned	Other Real Estate Owned: Other real estate owned acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less selling costs. Any write-down to fair value less cost to sell, at the time of transfer to other real estate owned is charged to the allowance for loan losses. Subsequent to foreclosure valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less costs to sell. Costs of improvements are capitalized, whereas costs relating to holding other real estate owned and subsequent write-downs to the value are expensed. As of December 31, 2021, the were no residential real estate properties where physical possession had been obtained and included with in other real estate owned assets and one property for $26 thousand at December 31, 2020. There were no residential real estate loans in the process of foreclosure at December 31, 2021, and five totaling $384 thousand at December 31, 2020.
Premises and Equipment	Premises and Equipment: Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets or the expected terms of the leases, if shorter. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured. Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Gains and losses on dispositions are included in current operations.
Goodwill and Intangible Assets	Goodwill and Intangible Assets: Goodwill represents the cost in excess of the fair value of net assets acquired (including identifiable intangibles) in transactions accounted for as business combinations. Goodwill has an indefinite useful life and is evaluated for impairment annually, or more frequently if events and circumstances indicate that the asset might be impaired. Other acquired intangible assets with finite lives, such as core deposit intangibles and customer list intangibles, are initially recorded at fair value and amortized over their estimated useful lives. Intangible assets are evaluated for impairment when events or changes in circumstances indicate a potential impairment.
Transfers of Financial Assets	Transfers of Financial Assets: Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company - put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Bank Owned Life Insurance	Bank Owned Life Insurance: The Company has purchased life insurance policies on certain key employees. The purchase of these life insurance policies allows the Company to use tax-advantaged rates of return. Bank-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.
Derivative Instruments	Derivative Instruments: The Company applies hedge accounting to certain interest rate derivatives entered into for risk management purposes. In accordance with ASC Topic 815, Derivatives and Hedging, all derivative instruments are recorded on the accompanying consolidated balance sheet at their respective fair values. The accounting for changes in fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship. If the derivative instrument is not designated as a hedge, changes in the fair value of the derivative instrument are recognized in earnings in the period of change. The Company enters into interest rate swaps (“swaps”) to facilitate customer transactions and meet their financial needs. Upon entering into these instruments to meet customer needs, the Company enters into offsetting positions with large U.S. financial institutions in order to minimize the risk to the Company. These swaps are derivatives, but are not designated as hedging instruments. For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. ​ Leases

Advertising Costs	Advertising Costs: The Company expenses all advertising and marketing costs as incurred.
Income Taxes	Income Taxes: The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. Deferred tax assets may be reduced by deferred tax liabilities and a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.
Stock-Based Compensation Plans	Stock-Based Compensation Plans: The Company has stock options, restricted stock awards and stock appreciation rights under stock-based compensation plans, which are described in more detail in Note 13-Employee Benefits. The plans have been accounted for under the accounting guidance (FASB ASC 718, Compensation Stock Compensation) The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employees’ service period, generally defined as the vesting period. For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award. A Black-Scholes model is used to estimate the fair value of stock options, while the market value of the Company’s common stock at the date of grant is used for restrictive stock awards and stock grants.
Comprehensive Income	Comprehensive Income: Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, primarily, (1) unrealized gains and losses on available-for-sale securities and (2) unrealized gains and losses on effective portions of fair value security hedges, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income.
Business Combinations	Business Combinations: Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method of accounting, acquired assets and assumed liabilities are included with the acquirer’s accounts as of the date of acquisition at estimated fair value, with any excess of purchase price over the fair value of the net assets acquired (including identifiable intangible assets) capitalized as goodwill. In the event that the fair value of the net assets acquired exceeds the purchase price, an acquisition gain is recorded for the difference in consolidated statements of income for the period in which the acquisition occurred. An intangible asset is recognized as an asset apart from goodwill when it arises from contractual or other legal rights or if it is capable of being separated or divided from the acquired entity and sold, transferred, licensed, rented or exchanged. In addition, acquisition-related costs and restructuring costs are recognized as period expenses as incurred. Estimates of fair value are subject to refinement for a period not to exceed one year from acquisition date as information relative to acquisition date fair values becomes available.
Earnings Per Common Share	Earnings Per Common Share: Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding and dilutive common share equivalents using the treasury stock method. Dilutive common share equivalents include common shares issuable upon exercise of outstanding stock options and restricted stock.
Operating Segments	Operating Segments: The Company’s chief operating decision maker primarily manages operations and assesses financial performance on a Company-wide basis. However, in addition to the discrete financial information that is provided for the Company as a whole, financial information is also provided for the wealth management services, insurance services and mortgage origination segments, respectively. While the chief operating decision maker uses the financial information related to these segments to analyze business performance and allocate resources, these segments do not meet the quantitative threshold under GAAP to be considered a reportable segment. As such, these operating segments, along with the banking operations segment, are aggregated into a single reportable operating
Recently Issued Not Yet Effective Accounting Pronouncements	Recently Issued Not Yet Effective Accounting Pronouncements: The following is a summary of recent authoritative pronouncements not yet in effect that could impact the accounting, reporting, and/or disclosure of financial information by the Company. In October 2019, the Financial Accounting Standards Board approved a delay for the implementation of ASU 2016-13, Financial Instruments - Credit Losses Under the CECL model, we will be required to present certain financial assets carried at amortized cost, such as loans held for investment and held-to-maturity debt securities, at the net amount expected to be collected. The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. This measurement will take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the “incurred loss” model currently required under GAAP, which delays recognition until it is probable a loss has been incurred. Accordingly, we expect that the adoption of the CECL model will materially affect how we determine our allowance for loan losses and could require us to significantly increase our allowance. Moreover, the CECL model may create more volatility in the level of our allowance for loan losses. If we are required to materially increase our level of allowance for loan losses for any reason, such increase could adversely affect our business, financial condition and results of operations. ​ A cross-functional working group comprised of individuals from credit administration, risk management and accounting and finance are in place implementing and developing the data, forecast, processes, and portfolio segmentation that will be used in the models that will estimate the expected credit loss for each loan segment. The Company has contracted with a third party vendor solution to assist us in the application, analysis, and model development required with implementation of ASU 2016-13. The Company is currently unable to reasonably estimate the impact of adopting ASU 2016-13, and it will be influenced by the composition, characteristics and quality of our loan and securities portfolio, as well as the economic conditions and forecasts as of each reporting period. These economic conditions and forecasts could be significantly different in future periods. ​ Recently Issued and Adopted Accounting Pronouncements: In December 2019, the FASB issued ASU No. 2019-12, “Simplifying the Accounting for Income Taxes.” accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. Finally, it clarifies that single-member limited liability companies and similar disregarded entities that are not subject to income tax are not required to recognize an allocation of consolidated income tax expense in their separate financial statements, but they could elect to do so. ASU 2019-12 is effective for interim and annual reporting periods beginning after December 15, 2020. ASU 2019-12 did not have a material impact on the Company’s Consolidated Financial Statements. In March 2020, the FASB issued ASU 2020-04 , Reference Rate Reform (Topic 848):
Operating, Accounting and Reporting Considerations related to COVID-19	Operating, Accounting and Reporting Considerations related to COVID-19: The COVID-19 pandemic has negatively impacted the global economy. In response to this crisis, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was passed by Congress and signed into law on March 27, 2020. The CARES Act provides an estimated $2.2 trillion to stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief through the COVID-19 pandemic. Some of the provisions applicable to the Company include, but are not limited to: ● Accounting for Loan Modifications – Section 4013 of the CARES Act provides that a financial institution may elect to suspend (1) the requirements under GAAP for certain loan modifications that would otherwise be categorized as a TDR and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes . See Note 5 Loans and Allowance for Loan Losses for more information. ● Paycheck Protection Program - The CARES Act established the Paycheck Protection Program (“PPP”), an expansion of the Small Business Administration’s (“SBA”) 7(a) loan program and the Economic Injury Disaster Loan Program (“EIDL”), administered directly by the SBA. The Company is a participant in the PPP. See Note 5 Loans and Allowance for Loan Losses for more information. ● Mortgage Forbearance - Under the CARES Act, through the earlier of December 31, 2020, or the termination date of the COVID-19 national emergency, a borrower with a federally backed mortgage loan that is experiencing financial hardship due to COVID-19 may request a forbearance. A multifamily borrower with a federally backed multifamily mortgage loan that was current as of February 1, 2020, and is experiencing financial hardship due to COVID-19 may request forbearance on the loan for up to 30 days, with up to two additional 30-day periods at the borrower’s request. Also in response to the COVID-19 pandemic, the Board of Governors of the Federal Reserve System (“FRB”), the Federal Deposit Insurance Corporation (“FDIC”), the National Credit Union Administration (“NCUA”), the Office of the Comptroller of the Currency (“OCC”), and the Consumer Financial Protection Bureau (“CFPB”), in consultation with the state financial regulators (collectively, the “agencies”) issued a joint interagency statement (issued March 22, 2020; revised statement issued April 7, 2020). Some of the provisions applicable to the Company include, but are not limited to: ● Accounting for Loan Modifications - Loan modifications that do not meet the conditions of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. The agencies confirmed with FASB staff that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or insignificant delays in payment. See Note 5 Loans and Allowance for Loan Losses for more information. ● Past Due Reporting - With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to COVID-19 as past due because of the deferral. A loan’s payment date is governed by the due date stipulated in the legal agreement. If a financial institution agrees to a payment deferral, these loans would not be considered past due during the period of the deferral. ● Nonaccrual Status and Charge-offs - During short-term COVID-19 modifications, these loans generally should not be reported as nonaccrual or as classified. The Company began offering short-term loan modifications to assist borrowers during the COVID-19 national emergency. The Company offered deferral options of: 1) three months deferral of payment and then three months of interest only, 2) three months of interest only, 3) three months deferral of payment, 4) six months of interest only. These modifications generally meet the criteria of both Section 4013 of the CARES Act and the joint interagency statement, and therefore, the Company does not account for such loan modifications as TDRs. On August 3, 2020, the Federal Financial Institutions Examination Council on behalf of its members (collectively “the FFIEC members”) issued a joint statement on additional loan accommodations related to COVID-19. The joint statement clarifies that for loan modifications in which Section 4013 is being applied, subsequent modifications could also be eligible under Section 4013. To be eligible, each loan modification must be (1) related to the COVID event; (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (A) 60 days after the date of termination of the National Emergency or (B) December 31, 2020. All of the Company’s loan modifications granted under Section 4013 of the CARES Act are in compliance with the aforementioned FFIEC requirements. Accordingly, the Company does not account for such loan modifications as TDRs.
