Accounting Policies [Abstract] |
Business activity | Southern First Bancshares, Inc. (the "Company") is a South Carolina corporation that owns all of the capital stock of Southern First Bank (the "Bank") and all of the stock of Greenville First Statutory Trust I and II (collectively, the "Trusts"). The Trusts are special purpose non-consolidated entities organized for the sole purpose of issuing trust preferred securities. The Bank's primary federal regulator is the Federal Deposit Insurance Corporation (the "FDIC"). The Bank is also regulated and examined by the South Carolina Board of Financial Institutions. The Bank is primarily engaged in the business of accepting demand deposits and savings deposits insured by the FDIC, and providing commercial, consumer and mortgage loans to the general public.
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Southern First Bank. In consolidation, all significant intercompany transactions have been eliminated. The accounting and reporting policies conform to accounting principles generally accepted in the United States of America. In accordance with guidance issued by the Financial Accounting Standards Board (“FASB”), the operations of the Trusts have not been consolidated in these financial statements.
Business Segments | Business Segments ASC Topic 280-10, “Segment Reporting,” requires selected segment information of operating segments based on a management approach. The Company’s three reportable segments represent the distinct product lines the Company offers and are viewed separately for strategic planning by management. Please refer to “Note 24 – Reportable Segments” for further information on the reporting for the Company’s three business segments.
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amount of income and expenses during the reporting periods. 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, derivatives, real estate acquired in settlement of loans, fair value of financial instruments, evaluating other-than-temporary-impairment of investment securities and valuation of deferred tax assets.
Risks and Uncertainties | Risks and Uncertainties In the normal course of its business, the Company encounters two significant types of risks: economic and regulatory. There are three main components of economic risk: interest rate risk, credit risk and market risk. The Company is subject to interest rate risk to the degree that its interest-bearing liabilities mature or reprice at different speeds, or on different bases, than its interest-earning assets. Credit risk is the risk of default within the Company’s loan portfolio that results from borrowers’ inability or unwillingness to make contractually required payments. Market risk reflects changes in the value of collateral underlying loans receivable and the valuation of real estate held by the Company. The Company is subject to the regulations of various governmental agencies. These regulations can and do change significantly from period to period. The Company also undergoes periodic examinations by the regulatory agencies, which may subject it to changes with respect to valuation of assets, amount of required loan loss allowance and operating restrictions resulting from the regulators’ judgments based on information available to them at the time of their examinations. The Bank makes loans to individuals and businesses in the Upstate, Midlands, and Lowcountry regions of South Carolina as well as the Triangle, Triad and Charlotte regions of North Carolina and Atlanta, Georgia for various personal and commercial purposes. The Bank’s loan portfolio has a concentration of real estate loans. As of December 31, 2021 and 2020, real estate loans represented 85.5% and 84.6%, respectively, of total loans. However, borrowers’ ability to repay their loans is not dependent upon any specific economic sector. The impact of the coronavirus (COVID-19) pandemic is fluid and continues to evolve, adversely affecting many of the Bank’s clients. The unprecedented and rapid spread of COVID-19 and its associated impacts on trade (including supply chains and export levels), travel, employee productivity, unemployment, consumer spending, and other economic activities has resulted in less economic activity, lower equity market valuations and significant volatility and disruption in financial markets, and has had an adverse effect on the Company’s business, financial condition and results of operations. The ultimate extent of the impact of the COVID-19 pandemic on our business, financial condition and results of operations is currently uncertain and will depend on various developments and other factors, including governmental and private sector initiatives, the effect of the recent rollout of vaccinations for the virus, whether such vaccinations will be effective against any resurgence of the virus, including any new strains, and the ability for customers and businesses to return to their pre-pandemic routine. 75 Table of Contents The Company’s business, financial condition and results of operations generally rely upon the ability of the Bank’s borrowers to repay their loans, the value of collateral underlying the Bank’s secured loans, and demand for loans and other products and services the Bank offers, which are highly dependent on the business environment in the Bank’s primary markets where it operates and in the United States as a whole. On March 3, 2020, the Federal Reserve reduced the target federal funds rate by 50 basis points, followed by an additional reduction of 100 basis points on March 16, 2020. These reductions in interest rates and other effects of the COVID-19 pandemic have had, and are expected to continue to have, possibly materially, an adverse effect on Company’s business, financial condition and results of operations. For instance, the pandemic has had negative effects on the Bank’s interest income, provision for loan losses, and certain transaction-based line items of noninterest income. Other financial impacts could occur though such potential impact is unknown at this time. As of December 31, 2021, the Company’s and the Bank’s capital ratios were in excess of all regulatory requirements. While management believes that we have sufficient capital to withstand an extended economic recession brought about by the COVID-19 pandemic, our reported and regulatory capital ratios could be adversely impacted by further credit losses. The Company maintains access to multiple sources of liquidity, including a $15.0 million holding company line of credit with another bank which could be used to support capital ratios at the subsidiary bank. As of December 31, 2021, the $15.0 million line was unused.
Subsequent Events | Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Management performed an evaluation to determine whether there have been any subsequent events since the balance sheet date and determined that no subsequent events occurred requiring accrual or disclosure.
Reclassifications | Reclassifications Certain amounts, previously reported, have been reclassified to state all periods on a comparable basis and had no effect on shareholders’ equity or net income.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks, interest bearing deposits and federal funds sold. Cash and cash equivalents have original maturities of three months or less, and federal funds sold are generally purchased and sold for one-day periods. Accordingly, the carrying value of these instruments is deemed to be a reasonable estimate of fair value. At December 31, 2021 and 2020, included in cash and cash equivalents was $5.2 million and $12.6 million, respectively, on deposit with the Federal Reserve Bank.
Investment Securities | Investment Securities We classify our investment securities as held to maturity securities, trading securities and available for sale securities as applicable. Investment securities are designated as held to maturity if we have the intent and the ability to hold the securities to maturity. Held to maturity securities are carried at amortized cost, adjusted for the amortization of any related premiums or the accretion of any related discounts into interest income using a methodology which approximates a level yield of interest over the estimated remaining period until maturity. Unrealized losses on held to maturity securities, reflecting a decline in value judged by us to be other than temporary, are charged to income in the Consolidated Statements of Income. Investment securities that are purchased and held principally for the purpose of selling in the near term are reported as trading securities. Trading securities are carried at fair value with unrealized holding gains and losses included in earnings. We classify investment securities as available for sale when at the time of purchase we determine that such securities may be sold at a future date or if we do not have the intent or ability to hold such securities to maturity. Securities designated as available for sale are recorded at fair value. Changes in the fair value of available for sale debt securities are included in shareholders’ equity as unrealized gains or losses, net of the related tax effect. Unrealized losses on available for sale securities, reflecting a decline in value judged to be other than temporary, are charged to income in the Consolidated Statements of Income. Realized gains or losses on available for sale securities are computed on the specific identification basis.
Other Investments | Other Investments Other investments include stock acquired for membership and regulatory purposes, such as Federal Home Loan Bank of Atlanta (“FHLB”) stock, investments in unconsolidated subsidiaries and other nonmarketable securities. FHLB stock is generally pledged against any borrowings from the FHLB and cash dividends on our FHLB stock are recorded in investment income. Other nonmarketable securities consist of investments in funds related to the Small Business Investment Company (“SBIC”) and Rural Business Investment Company (“RBIC”) Programs. No ready market exists for these stocks and they have no quoted market value. As a result, these securities are carried at cost and are periodically evaluated for impairment.
Loans | Loans Loans are stated at the principal balance outstanding. Unamortized net loan fees and the allowance for possible loan losses are deducted from total loans on the balance sheets. Interest income is recognized over the term of the loan based on the principal amount outstanding. The net of loan origination fees received and direct costs incurred in the origination of loans is deferred and amortized to interest income over the contractual life of the loans adjusted for actual principal prepayments using a method approximating the interest method.
Nonaccrual and Past Due Loans | Nonaccrual and Past Due Loans Loans are generally placed on nonaccrual status when principal or interest becomes 90 days past due, or when payment in full is not anticipated. When a loan is placed on nonaccrual status, interest accrued but not received is generally reversed against interest income. Cash receipts on nonaccrual loans are not recorded as interest income, but are used to reduce the loan’s principal balance. A nonaccrual loan is generally returned to accrual status and accrual of interest is resumed when payments have been made according to the terms and conditions of the loan for a continuous six month period. Our loans are considered past due when contractually required principal or interest payments have not been made on the due dates.
Nonperforming Assets | Nonperforming Assets Nonperforming assets include real estate acquired through foreclosure or deed taken in lieu of foreclosure, loans on nonaccrual status and loans past due 90 days or more and still accruing interest. Loans are placed on nonaccrual status when, in the opinion of management, the collection of additional interest is uncertain. Thereafter no interest is taken into income until such time as the borrower demonstrates the ability to pay both principal and interest.
Impaired Loans | Impaired Loans Our impaired loans include loans on nonaccrual status and loans modified in a troubled debt restructuring (“TDR”), whether on accrual or nonaccrual status. For loans that are classified as impaired, an allowance is established when the fair value (discounted cash flows, collateral value, or observable market price) of the impaired loan less costs to sell, are lower than the carrying value of that loan. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due, among other factors. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including, without limitation, the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for commercial and consumer loans by either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral if the loan is collateral dependent.
Loan Charge-off Policy | Loan Charge-off Policy For commercial loans, we generally fully charge off or charge collateralized loans down to net realizable value when management determines the loan to be uncollectible; repayment is deemed to be projected beyond reasonable time frames; the loan has been classified as a loss by either our internal loan review process or our banking regulatory agencies; the client has filed bankruptcy and the loss becomes evident owing to a lack of assets; or the loan is 120 days past due unless both well-secured and in the process of collection. For consumer loans, we generally charge down to net realizable value when the loan is 180 days past due.
Troubled Debt Restructuring (TDRs) | Troubled Debt Restructuring (TDRs) The Company considers a loan to be a TDR when the debtor experiences financial difficulties and the Company provides concessions such that we will not collect all principal and interest in accordance with the original terms of the loan agreement. Concessions can relate to the contractual interest rate, maturity date, or payment structure of the note. As part of our workout plan for individual loan relationships, we may restructure loan terms to assist borrowers facing challenges in the current economic environment. In accordance with the CARES Act, the Company implemented loan modification programs in response to the COVID-19 pandemic, and the Company elected the accounting policy in the CARES Act to not apply TDR accounting to loans modified for borrowers impacted by the COVID-19 pandemic. In 2020, the Company granted short-term loan deferrals to six client relationships which were considered TDRs due to the client experiencing financial difficulty before the pandemic. Our policy with respect to accrual of interest on loans restructured in a TDR follows relevant supervisory guidance. That is, if a borrower has demonstrated performance under the previous loan terms and shows capacity to perform under the restructured loan terms; continued accrual of interest at the restructured interest rate is likely. If a borrower was materially delinquent on payments prior to the restructuring, but shows capacity to meet the restructured loan terms, the loan will likely continue as nonaccrual going forward. Lastly, if the borrower does not perform under the restructured terms, the loan is placed on nonaccrual status. We will continue to closely monitor these loans and will cease accruing interest on them if management believes that the borrowers may not continue performing based on the restructured note terms. If, after previously being classified as a TDR, a loan is restructured a second time and the borrower continues to experience financial difficulties, then that loan is automatically placed on nonaccrual status. Our policy with respect to nonperforming loans requires the borrower to make a minimum of six consecutive payments of principal and interest in accordance with the loan terms before that loan can be placed back on accrual status. Further, the borrower must show capacity to continue performing into the future prior to restoration of accrual status. In addition, our policy, in accordance with supervisory guidance, also provides for a loan to be removed from TDR status if the loan is modified or renewed at terms consistent with current market rates and the loan has been performing under modified terms for an extended period of time or under certain circumstances. 78 Table of Contents In the determination of the allowance for loan losses, management considers TDRs on commercial and consumer loans and subsequent defaults in these restructurings by measuring impairment, on a loan by loan basis, based on either the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's obtainable market price, or the fair value of the collateral, less costs to sell, if the loan is collateral dependent.
Allowance for Loan Losses | Allowance for Loan Losses The allowance for loan losses is management’s estimate of credit losses inherent in the loan portfolio. The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the 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. We have an established process to determine the adequacy of the allowance for loan losses that assesses the losses inherent in our portfolio. While we attribute portions of the allowance to specific portfolio segments, the entire allowance is available to absorb credit losses inherent in the total loan portfolio. Our process involves procedures to appropriately consider the unique risk characteristics of our commercial and consumer loan portfolio segments. For each portfolio segment, impairment is measured individually for each impaired loan. Our allowance levels are influenced by loan volume, loan grade or delinquency status, historic loss experience and other economic conditions. See Note 4 to the Consolidated Financial Statements for additional information on the allowance for loan losses.
Other Real Estate Owned | Other Real Estate Owned Real estate acquired through foreclosure is initially recorded at the lower of cost or estimated fair value less selling costs. Subsequent to the date of acquisition, it is carried at the lower of cost or fair value, adjusted for net selling costs. Fair values of real estate owned are reviewed regularly and write-downs are recorded when it is determined that the carrying value of real estate exceeds the fair value less estimated costs to sell. Costs relating to the development and improvement of such property are capitalized, whereas those costs relating to holding the property are expensed.
Property and Equipment | Property and Equipment Property and equipment are stated at cost. Major repairs are charged to operations, while major improvements are capitalized. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets. Upon retirement, sale, or other disposition of property and equipment, the cost and accumulated depreciation are eliminated from the accounts, and gain or loss is included in income from operations. Construction in progress is stated at cost, which includes the cost of construction and other direct costs attributable to the construction. No provision for depreciation is made on construction in progress until such time as the relevant assets are completed and put into use.
Operating Leases | Operating Leases Effective January 1, 2019, the Company adopted ASU 2016-02, “Leases (Topic 842)” which requires for all operating leases the recognition of a right-of-use (“ROU”) asset and a corresponding lease liability, in the balance sheet. Upon adoption, the Company elected practical expedients including existing leases retaining their classification as operating leases and combining lease and non-lease components. The Company also elected to not recognize right-of-use assets and lease liabilities arising from short-term leases.
Bank Owned Life Insurance Policies | Bank Owned Life Insurance Policies Bank owned life insurance policies represent the cash value of policies on certain officers of the Company.
Comprehensive Income | Comprehensive Income Comprehensive income (loss) consists of net income and net unrealized gains (losses) on securities and is presented in the statements of shareholders’ equity and comprehensive income. The statement requires only additional disclosures in the consolidated financial statements; it does not affect our results of operations.
Revenue from Contracts with Customers | Revenue from Contracts with Customers The Company records revenue from contracts with customers in accordance with Accounting Standards Codification Topic 606, “Revenue from Contracts with Customers” (“Topic 606”). Under Topic 606, the Company must identify the contract with a customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue when (or as) the Company satisfies a performance obligation. Significant revenue has not been recognized in the current reporting period that results from performance obligations satisfied in previous periods. The Company’s primary sources of revenue are derived from interest and dividends earned on loans, investment securities, and other financial instruments that are not within the scope of Topic 606. The Company has evaluated the nature of its contracts with customers and determined that further disaggregation of revenue from contracts with customers into more granular categories beyond what is presented in the Consolidated Statements of Income was not necessary. The Company generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, the Company has made no significant judgments in applying the revenue guidance prescribed in Topic 606 that affect the determination of the amount and timing of revenue from contracts with customers.
Income Taxes | Income Taxes The financial statements have been prepared on the accrual basis. When income and expenses are recognized in different periods for financial reporting purposes versus for the purposes of computing income taxes currently payable, deferred taxes are provided on such temporary differences. Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in the consolidated financial statements or tax returns. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realized or settled. The Company believes that its income tax filing positions taken or expected to be taken on its tax returns will more likely than not be sustained upon audit by the taxing authorities and does not anticipate any adjustments that will result in a material adverse impact on the Company’s financial condition, results of operations, or cash flow. Therefore, no reserves for uncertain income tax positions have been recorded. The Company’s federal and state income tax returns are open and subject to examination from the 2018 tax return year and forward.
Stock-Based Compensation | Stock-Based Compensation The Company has a stock-based employee compensation plan. Compensation cost is recognized for all stock options granted and for any outstanding unvested awards as if the fair value method had been applied to those awards as of the date of grant.
Newly Issued, But Not yet Effective Accounting Standards | Newly Issued, But Not yet Effective Accounting Standards ASU 2016-13 – Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard will replace the current incurred loss approach with an expected loss model, referred to as the current expected credit loss (“CECL”) model. The new standard will apply to financial assets subject to credit losses and measured at amortized cost and certain off-balance-sheet credit exposures, which include, but are not limited to, loans, leases, held-to-maturity securities, loan commitments and financial guarantees. ASU 2016-13 simplifies the accounting for purchased credit-impaired debt securities and loans and expands the disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. For public business entities that meet the definition of a smaller reporting company, such as the Company, the ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2022. Early adoption is permitted in any interim period as long as the Company has adopted to the amendments in ASU 2016-13. Upon adoption, ASU 2016-13 provides for a modified retrospective transition by means of a cumulative effect adjustment to equity as of the beginning of the period in which the guidance is effective. The Company is finalizing its evaluation of the adoption of this ASU and plans to early adopt as of January 1, 2022. The Company to date has selected the software vendor of choice for implementation, sourced and tested required data from the Company’s loan systems, tested data feeds to the model, contracted for and received results from independent third parties of model validation of the CECL model and process, determined appropriate segmentations of its portfolio, selected a preliminary forecast period for reasonable and supportable forecasts, and has performed parallel runs of the model. The Company is currently finalizing its assessment of current and forecasted macroeconomic factors and assumptions and testing and finalization of internal controls. The Company currently estimates the allowance for loan losses will increase by a range of $1 million and $3 million. In addition, the Company expects to recognize a liability for unfunded commitments between $2.5 million and $4 million upon adoption. The Company will finalize the adoption during the first quarter of 2022. In October 2020, the FASB updated various Topics of the Accounting Standards Codification to align the guidance in various SEC sections of the Codification with the requirements of certain SEC final rules. The amendments were effective upon issuance and did not have a material effect on the financial statements. In August 2021, the FASB issued amendments to update SEC paragraphs in the Accounting Standards Codification to reflect the issuance of SEC Release No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants. The amendments are effective upon issuance. The Company does not expect these amendments to have a material effect on its financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption.
