Organization, Consolidation and Presentation of Financial Statements [Abstract]

Presentation of Financial Information

Note 1. Presentation of Financial Information

Nature of Business:

SmartFinancial, Inc. (the "Company" or “SmartFinancial”) 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 the Florida Panhandle. The Bank’s primary deposit products are noninterest-bearing and 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 and Accounting Estimates:

The accounting and financial reporting policies of the Company and its wholly owned subsidiary conform to U.S. generally accepted accounting principles (“GAAP”) and reporting guidelines of banking regulatory authorities and regulators. The accompanying interim consolidated financial statements for the Company and its wholly owned subsidiary have not been audited. All material intercompany balances and transactions have been eliminated.

In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments are normal and recurring accruals considered necessary for a fair and accurate presentation. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan and lease losses, the valuation of foreclosed assets and deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and the fair value of assets acquired, and liabilities assumed in acquisitions. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in the Company’s annual report on Form 10-K for the year ended December 31, 2020.

Recently Issued and Adopted Accounting Pronouncements:

In December 2019, the FASB issued ASU No. 2019-12, “Simplifying the Accounting for Income Taxes.” This ASU simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the 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.

Recently Issued Not Yet Effective Accounting Pronouncements:

During interim periods, the Company follows the accounting policies set forth in its annual audited financial statements for the year ended December 31, 2020, as filed in its Annual Report on Form 10-K with the Securities and Exchange Commission ("SEC"). The following is a summary of recent authoritative pronouncements issued but not yet effective 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 (Topic 326). The Board decided that the Current Expected Credit Loss (“CECL”) model will be effective for larger Public Business Entities ("PBEs") that are SEC filers, excluding Smaller Reporting Companies ("SRCs") as currently defined by the SEC, for fiscal years beginning after December 15, 2019, and interim

periods within those fiscal years. For calendar-year-end companies that are not SRCs, this will be January 1, 2020. The determination of whether an entity is an SRC will be based on an entity’s most recent assessment in accordance with SEC regulations and the Company meets the regulations as an SRC. For SRCs and other entities, the Board decided that CECL will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For all entities, early adoption will continue to be permitted; that is, early adoption is allowed for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (that is, effective January 1, 2019, for calendar-year-end companies). The Company does not plan to adopt this standard early and being that the Company is an SRC, adoption is required for fiscal years beginning after December 15, 2022.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference London Interbank Offered Rate (“LIBOR”). It is intended to help stakeholders during the global market-wide reference rate transition period. The Company is implementing a transition plan to identify and modify its loans and other financial instruments, including certain indebtedness, with attributes that are either directly or indirectly influenced by LIBOR. The Company is assessing ASU 2020-04 and its impact on the transition away from LIBOR for its loan and other financial instruments.

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 Act (“CARES Act”) was passed by Congress and signed into law on March 27, 2020. The CARES Act provides an estimated $2.2 trillion to fight the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. 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 Leases and Allowance for Loan and Lease 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. On December 27, 2020, the Consolidated Appropriations Act, 2021 (“CAA”) was signed into law. The CAA provides several amendments to the PPP, including additional funding for first and second draws of PPP loans up to March 31, 2021. On March 30, 2021, the PPP Extension Act of 2021 was signed into law, which extends the program to May 31, 2021. The Company is a participant in the PPP. See Note 5 - Loans and Leases and Allowance for Loan and Lease Losses for more information.

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 Leases and Allowance for Loan and Lease Losses for more information.

●

Past Due Reporting - Regarding 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.

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. The December 31, 2020, deadline was subsequently extended to January 1, 2022, by the CAA. 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.

Sevier County Bancshares, Inc.

On September 1, 2021, the Company completed the acquisition of Sevier County Bancshares, Inc., a Tennessee corporation (“SCB”), pursuant to an Agreement and Plan of Merger dated April 13, 2021 (the “Merger Agreement”).

In connection with the merger, the Company acquired $484.9 million of assets and assumed $443.1 million of liabilities. Pursuant to the Merger Agreement, at the effective time of the merger, SCB shareholders were entitled to receive for each share of SCB common stock, no par value per share, outstanding immediately prior to the Merger, either (i) $10.17 in cash (the “Per Share Cash Consideration”), or (ii) 0.4116 shares of Company common stock, par value $1.00 (the “Per Share Stock Consideration”). Pursuant to the terms of the Merger Agreement, (i) each SCB shareholder holding 20,000 shares or more of SCB common stock will receive the Per Share Stock Consideration and (ii) each SCB shareholder holding fewer than 20,000 shares of SCB common stock may elect to receive either the Per Share Stock Consideration or the Per Share Cash Consideration. SmartFinancial issued 1,691,535 shares of SmartFinancial common stock and paid $9.6 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 $15.6 million, representing the intangible value of SCB’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 $1.6 million using the effective yield method over 120 months (10 years), which represents the expected useful life of the asset.

The purchased assets and assumed liabilities were recorded at their acquisition date fair values ⁽¹⁾ and are summarized in the table below (in thousands).

Fountain Leasing, LLC

On May 3, 2021, the Company completed the acquisition of Fountain Leasing, LLC, a Tennessee limited liability company, pursuant to the Purchase Agreement (the “Purchase Agreement”), dated May 2, 2021, by and among the Bank and the members of Fountain Leasing, LLC. 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. In addition to the closing consideration, the Purchase Agreement contains a performance-based earnout, pursuant to which the former members of Fountain could be entitled to up to $6.0 million, which is excluded from consideration pursuant to ASC 805, in future cash payments from the Company based on future results of the acquired business over various periods through December 31, 2026. 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 $2.4 million, representing the intangible value of Fountains business and reputation within the markets it served. The goodwill recognized is expected to be deductible for income tax purposes. The Company established an intangible asset related to customer relationships of $2.7 million, amortizing sum-of-the-years digits over 96 months (8 years).

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.)

Earnings Per Share

Note 3. Earnings Per Share

Basic earnings per common share is computed by dividing net income available to common shareholders 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. The effect from the stock options and restricted stock on incremental shares from the assumed conversions for net income per share-basic and net income per share-diluted are presented below. There were no antidilutive shares for the three and nine months ended September 30, 2021. There were 114 thousand and 85 thousand antidilutive shares for the three and nine months ended September 30, 2020, respectively.

The following is a summary of the basic and diluted earnings per share computation (dollars in thousands, except per share data):

The Company reviews the securities portfolio on a quarterly basis to monitor its exposure to other-than-temporary impairment. 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 September 30, 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 September 30, 2021, the Company does not intend, or be required, to sell any of the securities, and expects to recover the entire amortized cost of all of the securities.

The following is the amortized cost and carrying value of other investments (in thousands):


	September 30,		December 31,
	2021		2020
Federal Reserve Bank stock	$	8,171	$	8,606
Federal Home Loan Bank stock		6,451		5,838
First National Bankers Bank stock		350		350
Total	$	14,972	$	14,794

Our restricted investments consist of 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 September 30, 2021, the Company determined that there was no impairment on its other investments.

¹Purchased Credit Impaired loans and leases (“PCI loans and leases”) are loans and leases with evidence of credit deterioration at purchase.

For purposes of the disclosures required pursuant to ASC 310, the loan and lease portfolio was disaggregated into segments. 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.

As previously mentioned in Note 1 – Presentation of Financial Information, the CARES Act established the PPP, administered directly by the SBA. The PPP provides loans of up to $10 million to small businesses who were affected by economic conditions as a result of COVID-19 to provide cash-flow assistance to employers who maintain their payroll (including healthcare and certain related expenses), mortgage interest, rent, leases, utilities and interest on existing debt during the COVID-19 emergency. PPP loans carry an interest rate of one percent, and a maturity of two or five years. These loans are fully guaranteed by the SBA and are not included in the Company’s loan and lease loss allowance calculations. The loans may be eligible for forgiveness by the SBA to the extent that the proceeds are used to cover eligible payroll costs, interest costs, rent, and utility costs over a period of up to 24 weeks after the loan is made as long as certain conditions are met regarding employee retention and compensation levels. PPP loans deemed eligible for forgiveness by the SBA will be repaid by the SBA to the Company. The SBA pays the Company fees for processing PPP loans and the fees are accounted for as loan origination fees and recognized over the contractual loan term as a yield adjustment on the loans. At September 30, 2021, the net deferred fees outstanding was $3.8 million for the 2021 PPP loans and no net deferred fees were outstanding for the 2020 PPP loans. At December 31, 2020, the net deferred fees outstanding for the 2020 PPP loans was $4.2 million. PPP loans are included in the Commercial and Industrial loan segments. As of September 30, 2021, the Company had 1,126 PPP loans outstanding, with an outstanding principal balance of $87.1 million and as of December 31, 2020, the Company had 2,863 PPP loans outstanding, with an outstanding principal balance of $288.9 million.

We maintain the allowance at a level that we deem appropriate to adequately cover the probable losses inherent in the loan and lease portfolio. Our provision for loan and lease losses for the three and nine months ended September 30, 2021, is $1.1 million and $1.2 million, respectively, and $2.6 million $8.7 million, during the three and nine months ended September 30, 2020, respectively. As of September 30, 2021, and December 31, 2020, our allowance for loan and lease losses was $19.3 million and $18.3 million, respectively, which we deemed to be adequate at each of the respective dates. Our allowance for loan and lease losses as a percentage of total loans and leases was 0.73% at September 30, 2021 and 0.77% at December 31, 2020.

Past Due Loans and Leases:

A loan or lease is considered past due if any required principal and interest payments have not been received as of the date such payments were required to be made under the terms of the loan or lease agreement. Generally, management places a loan or lease on nonaccrual when there is a clear indicator that the borrower’s cash flow may not be sufficient to meet payments as they become due, which is generally when a loan or lease is 90 days past due.

Troubled Debt Restructurings:

For the periods presented, 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 September 30, 2021 and December 31, 2020, management had approximately $212 thousand and $257 thousand, respectively, in loans that met the criteria for TDR, 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 the Company will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.

There were no loans that were modified as a TDR during the nine months ended September 30, 2021, and one loan that was modified during the nine months ended September 30, 2020. There were no loans that were modified as TDRs during the past nine months and for which there was a subsequent payment default.

The Company began offering short-term loan modifications to assist borrowers during the COVID-19 national emergency. 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 for more information. At September 30, 2021, the Company had no loans remaining under COVID-19 modifications.

Foreclosure Proceedings and Balances:

As of September 30, 2021, there were no residential properties secured by real estate included in other real estate owned and there was one residential real estate loan totaling $33 thousand in the process of foreclosure.

Goodwill and Intangible Assets

Note 6. Goodwill and Intangible Assets

In accordance with FASB ASC 350, Goodwill and Other, regarding testing goodwill for impairment provides an entity the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company performs its annual goodwill impairment test as of December 31 of each year. Considering the recent economic conditions resulting from the COVID-19 pandemic the Company performed a Step 1 goodwill impairment test (which compares the fair value of a reporting unit with its carrying amount, including goodwill) at December 31, 2020, the results indicated that there was no impairment. Management will continue to evaluate the economic conditions at future reporting periods for applicable changes.

On September 30, 2021, the Company entered into a Purchase and Assumption Agreement and completed the sale of a portfolio of loans and certain assets associated (the “Sale”) with its branch office located in Richmond, Virginia to Strasburg, Virginia-based First Bank. In accordance with GAAP, the Company allocated a proportionate share of its goodwill balance to the Sale on a relative fair value basis. Based on a relative fair value analysis performed through the date of the sale, goodwill adjustment in the amount of $2.5 million related to the Sale was recorded during the third quarter of 2021.

The Company’s other intangible assets consist of core deposit, customer relationships and tradename. They are initially recognized based on a valuation performed as of the consummation date. The core deposit intangible is amortized over the average remaining life of the acquired customer deposits, the customer relationships are amortized over a weighted average of 8.6 years and the tradename is amortized over five years.

The carrying amount of goodwill and other intangible assets as of the dates indicated is summarized below (in thousands):

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 9. Commitments and Contingent Liabilities

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 on the balance sheet. 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 are as follows (in thousands):


	September 30,		December 31,
	2021		2020
Commitments to extend credit	$	616,271	$	476,841
Standby letters of credit		10,439		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 September 30, 2021 and December 31, 2020, the carrying amount of liabilities related to the Company’s obligation to perform under standby letters of credit was insignificant.

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.

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 - Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

Level 2 - Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3 - Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant management judgment or estimation.

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.

During the nine months ending September 30, 2021, there were no transfers between Level 1 and Level 2 in the fair value hierarchy.

Securities available-for-sale - The fair value of U.S. Treasury, U.S. Government-sponsored enterprises, municipal securities, other debt securities and mortgage-backed securities, is estimated using a third party pricing service. The third 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.

Derivative financial instruments - The fair value for derivative financial instruments is determined based on market prices, broker-dealer quotations on similar products, or other related input parameters. The derivative financial instruments are generally classified Level 2.

Assets Measured at Fair Value on a Nonrecurring Basis:

Under certain circumstances management adjusts fair value for assets and liabilities although they are not measured at fair value on an ongoing basis. The following tables present the financial instruments carried on the consolidated balance sheets by caption and by level in the fair value hierarchy, for which a nonrecurring change in fair value has been recorded (in thousands):


			Quoted Prices in		Significant		Significant
			Active Markets		Other		Other
			for Identical		Observable		Unobservable

Other real estate owned		4,619		—		—		4,619

For Level 3 assets measured at fair value on a non-recurring basis, the significant unobservable inputs used in the fair value measurements are presented below (dollars in thousands):


					Weighted
			Valuation	Significant Other	Average of
	Fair Value		Technique	Unobservable Input	Input
September 30, 2021:
Collateral dependent loans	$	2,868	Appraisal	Appraisal discounts	26	%
Other real estate owned		2,415	Appraisal	Appraisal discounts	10	%

December 31, 2020:
Collateral dependent loans	$	2,455	Appraisal	Appraisal discounts	9	%
Other real estate owned		4,619	Appraisal	Appraisal discounts	22	%

Collateral dependent loans: A collateral dependent loan is measured based on the fair value of the collateral securing these loans, less selling costs. Collateral dependent loans are classified within Level 3 of the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory, and/or accounts receivable. The Company determines the value of the collateral based on independent appraisals performed by qualified licensed appraisers. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised values are discounted for costs to sell and may be discounted further based on management’s historical knowledge, changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such discounts by management are subjective and are typically significant unobservable inputs for determining fair value. Colleterial dependent loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors discussed above.

Other real estate owned: Other real estate owned, consisting of properties obtained through foreclosure or in satisfaction of loans, are initially recorded at fair value less estimated costs to sell upon transfer of the loans to other real estate. Subsequently, other real estate is carried at the lower of carrying value or fair value less costs to sell. Fair values are generally based on third party appraisals of the property and are classified within Level 3 of the fair value hierarchy. The appraisals are sometimes further discounted based on management’s historical knowledge, and/or changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such discounts are typically significant unobservable inputs for determining fair value. In cases where the carrying amount exceeds the fair value, less estimated costs to sell, the difference is recognized in noninterest expense.

Limitations:

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. 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 11.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, which allows such partial term hedge designations.

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 instruments and are recorded at fair value in other assets and other liabilities. Since the income statement impact of the offsetting positions is limited, any changes in fair value is recognized as other noninterest income in the current period.

At September 30, 2021 and December 31, 2020, interest rate swaps related to the Company’s loan hedging program that were outstanding are presented in the following table (in thousands):

Leases [Abstract]

Leases

Note 12. 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):


		September 30,		December 31,
	Classification	2021		2020
Assets:
Operating lease right-of-use assets	Other assets	$	6,104	$	4,797
Liabilities:
Operating lease liabilities	Other liabilities	$	6,154	$	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 at the Company’s discretion. If, at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019, was used.

As of September 30, 2021, the weighted average remaining lease term was 10.80 years and the weighted average discount rate was 2.39%.

The following table represents lease costs and other lease information. As 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 (in thousands).

Regulatory Matters

Note 13. 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 September 30, 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 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 three months ended September 30, 2021, the Bank did not pay a dividend to the Company and the Company paid a quarterly common stock dividend of $0.06 per share. During the nine months ended September 30, 2021, the Bank paid $10.0 million in dividends to the Company. Since the first quarter of 2021, the Company has paid a quarterly common stock dividend of $0.06 per share. 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature of Business

Nature of Business:

SmartFinancial, Inc. (the "Company" or “SmartFinancial”) 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 the Florida Panhandle. The Bank’s primary deposit products are noninterest-bearing and 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 and Accounting Estimates

Basis of Presentation and Accounting Estimates:

The accounting and financial reporting policies of the Company and its wholly owned subsidiary conform to U.S. generally accepted accounting principles (“GAAP”) and reporting guidelines of banking regulatory authorities and regulators. The accompanying interim consolidated financial statements for the Company and its wholly owned subsidiary have not been audited. All material intercompany balances and transactions have been eliminated.

In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying financial statements have been made. These adjustments are normal and recurring accruals considered necessary for a fair and accurate presentation. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan and lease losses, the valuation of foreclosed assets and deferred taxes, other than temporary impairments of securities, the fair value of financial instruments, goodwill, and the fair value of assets acquired, and liabilities assumed in acquisitions. The results for interim periods are not necessarily indicative of results for the full year or any other interim periods. The accompanying unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in the Company’s annual report on Form 10-K for the year ended December 31, 2020.

Recently Issued Not Yet Effective Accounting Pronouncements

Recently Issued and Adopted Accounting Pronouncements:

In December 2019, the FASB issued ASU No. 2019-12, “Simplifying the Accounting for Income Taxes.” This ASU simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 740 related to the approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The new guidance also simplifies aspects of the 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.

Recently Issued Not Yet Effective Accounting Pronouncements:

During interim periods, the Company follows the accounting policies set forth in its annual audited financial statements for the year ended December 31, 2020, as filed in its Annual Report on Form 10-K with the Securities and Exchange Commission ("SEC"). The following is a summary of recent authoritative pronouncements issued but not yet effective 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 (Topic 326). The Board decided that the Current Expected Credit Loss (“CECL”) model will be effective for larger Public Business Entities ("PBEs") that are SEC filers, excluding Smaller Reporting Companies ("SRCs") as currently defined by the SEC, for fiscal years beginning after December 15, 2019, and interim

periods within those fiscal years. For calendar-year-end companies that are not SRCs, this will be January 1, 2020. The determination of whether an entity is an SRC will be based on an entity’s most recent assessment in accordance with SEC regulations and the Company meets the regulations as an SRC. For SRCs and other entities, the Board decided that CECL will be effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. For all entities, early adoption will continue to be permitted; that is, early adoption is allowed for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (that is, effective January 1, 2019, for calendar-year-end companies). The Company does not plan to adopt this standard early and being that the Company is an SRC, adoption is required for fiscal years beginning after December 15, 2022.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference London Interbank Offered Rate (“LIBOR”). It is intended to help stakeholders during the global market-wide reference rate transition period. The Company is implementing a transition plan to identify and modify its loans and other financial instruments, including certain indebtedness, with attributes that are either directly or indirectly influenced by LIBOR. The Company is assessing ASU 2020-04 and its impact on the transition away from LIBOR for its loan and other financial instruments.

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 Act (“CARES Act”) was passed by Congress and signed into law on March 27, 2020. The CARES Act provides an estimated $2.2 trillion to fight the COVID-19 pandemic and stimulate the economy by supporting individuals and businesses through loans, grants, tax changes, and other types of relief. 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 Leases and Allowance for Loan and Lease 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. On December 27, 2020, the Consolidated Appropriations Act, 2021 (“CAA”) was signed into law. The CAA provides several amendments to the PPP, including additional funding for first and second draws of PPP loans up to March 31, 2021. On March 30, 2021, the PPP Extension Act of 2021 was signed into law, which extends the program to May 31, 2021. The Company is a participant in the PPP. See Note 5 - Loans and Leases and Allowance for Loan and Lease Losses for more information.

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 Leases and Allowance for Loan and Lease Losses for more information.

●

Past Due Reporting - Regarding 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.

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. The December 31, 2020, deadline was subsequently extended to January 1, 2022, by the CAA. 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.

Reclassifications

Reclassifications:

Certain captions and amounts in the 2020 consolidated financial statements were reclassified to conform to the 2021 financial statement presentation. These reclassifications had no impact on net income or shareholders’ equity as previously reported.

Earnings Per Share

Basic earnings per common share is computed by dividing net income available to common shareholders 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.

Fair Value Measurement Inputs and Valuation Techniques

For Level 3 assets measured at fair value on a non-recurring basis, the significant unobservable inputs used in the fair value measurements are presented below (dollars in thousands):


					Weighted
			Valuation	Significant Other	Average of
	Fair Value		Technique	Unobservable Input	Input
September 30, 2021:
Collateral dependent loans	$	2,868	Appraisal	Appraisal discounts	26	%
Other real estate owned		2,415	Appraisal	Appraisal discounts	10	%

December 31, 2020:
Collateral dependent loans	$	2,455	Appraisal	Appraisal discounts	9	%
Other real estate owned		4,619	Appraisal	Appraisal discounts	22	%

Collateral dependent loans: A collateral dependent loan is measured based on the fair value of the collateral securing these loans, less selling costs. Collateral dependent loans are classified within Level 3 of the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory, and/or accounts receivable. The Company determines the value of the collateral based on independent appraisals performed by qualified licensed appraisers. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised values are discounted for costs to sell and may be discounted further based on management’s historical knowledge, changes in market conditions from the date of the most recent appraisal, and/or management’s expertise and knowledge of the customer and the customer’s business. Such discounts by management are subjective and are typically significant unobservable inputs for determining fair value. Colleterial dependent loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors discussed above.

- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.
