Summary of Significant Accounting Policies

NOTE 1 – Summary of Significant Accounting Policies

Nature of Business

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 Trusts 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

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three- and nine- month period ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 as filed with the U.S. Securities and Exchange Commission (“SEC”) on March 4, 2022. The consolidated financial statements include the accounts of the Company and the Bank. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, “Consolidation,” the financial statements related to the Trusts have not been consolidated.

Business Segments

The Company, through the Bank, provides a broad range of financial services to individuals and companies in South Carolina, North Carolina, and Georgia. These services include demand, time and savings deposits; lending services; ATM processing and mortgage banking services. While the Company’s management periodically reviews limited production information for these revenue streams, that information is not complete as it does not include a full allocation of revenue, costs and capital from key corporate functions. Management will continue to evaluate these lines of business for separate reporting as facts and circumstances change.  Accordingly, the Company’s various banking operations are not considered by management to constitute more than one reportable operating segment.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP 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 credit losses, real estate acquired in the settlement of loans, fair value of financial instruments, evaluating other-than-temporary-impairment of investment securities and valuation of deferred tax assets.

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.

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.

Adoption of New Accounting Standard

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326). The ASU introduces a new credit loss methodology, the Current Expected Credit Loss (“CECL”) methodology, which requires earlier recognition of credit losses, while also providing additional transparency about credit risk. Since its original issuance in 2016, the FASB has issued several updates to the original ASU.

The CECL methodology utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses for loans, held-to-maturity securities and other receivables at the time the financial asset is originated or acquired. It also applies to off-balance sheet credit exposures, such as unfunded commitments to extend credit. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. The methodology replaces the multiple existing impairment methods in current GAAP, which generally require that a loss be incurred before it is recognized. For available-for-sale securities where fair value is less than cost, credit-related impairment, if any, is recognized through an allowance for credit losses and adjusted each period for changes in credit risk.

On January 1, 2022, the Company adopted the guidance prospectively with a cumulative adjustment to retained earnings. Results for reporting periods beginning after January 1, 2022 are presented under CECL while prior period amounts continue to be reported in accordance with the previously applicable incurred loss accounting methodology. The transition adjustment for the adoption of CECL included an increase in the allowance for credit losses on loans of $1.5 million and an increase in the reserve for unfunded loan commitments of $2.0 million, which is recorded within other liabilities. The adoption of CECL had an insignificant impact on the Company’s investment securities portfolio. The Company recorded a net decrease to retained earnings of $2.8 million as of January 1, 2022 for the cumulative effect of adopting CECL, which reflects the transition adjustments noted above, net of the applicable deferred tax assets recorded. Federal banking regulatory agencies provided optional relief to delay the adverse regulatory capital impact of CECL at adoption. The Company did not elect to use this optional relief.

Significant Accounting Policy Changes

Upon adoption of ASC 326, the Company revised the accounting policy for the Allowance for Credit Losses as detailed below. 

Allowance for Credit Losses - Securities Available for Sale

For available for sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or if it is more likely than not that it will be required to sell the security before recovery of the amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income with the establishment of an allowance under CECL compared to a direct write down of the security under Incurred Loss. For debt securities available for sale that do not meet the aforementioned criteria, the Company evaluates whether any decline in fair value is due to credit loss factors. In making this assessment, management considers any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income.

Changes in the allowance for credit losses under CECL are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. At September 30, 2022, there was no allowance for credit losses related to the available-for-sale portfolio.

Accrued interest receivable on available for sale debt securities totaled $477,000 at September 30, 2022 and was excluded from the estimate of credit losses.

Allowance for Credit Losses - Loans

Under the current expected credit loss model, the allowance for credit losses on loans is a valuation allowance estimated at each balance sheet date in accordance with GAAP that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans.

Management assesses the adequacy of the allowance on a quarterly basis. This assessment includes procedures to estimate the allowance and test the adequacy and appropriateness of the resulting balance. The level of the allowance is based upon management’s evaluation of historical default and loss experience, current and projected economic conditions, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers’ ability to repay a loan, the estimated value of any underlying collateral, composition of the loan portfolio, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. Management believes the level of the allowance for credit losses is adequate to absorb all expected future losses inherent in the loan portfolio at the balance sheet date. The allowance is increased through provision for credit losses and decreased by charge-offs, net of recoveries of amounts previously charged-off.

The allowance for credit losses is measured on a collective basis for pools of loans with similar risk characteristics. The Company has identified the following pools of financial assets with similar risk characteristics for measuring expected credit losses:

Commercial loans

● Owner occupied real estate - Owner occupied commercial mortgages consist of loans to purchase or re-finance owner occupied nonresidential properties. This includes office buildings, other commercial facilities, and farmland. Commercial mortgages secured by owner occupied properties are primarily dependent on the ability of borrowers to achieve business results consistent with those projected at loan origination. While these loans and leases are collateralized by real property in an effort to mitigate risk, it is possible the liquidation of collateral will not fully satisfy the obligation.

● Non-owner occupied real estate - Non-owner occupied commercial mortgages consist of loans to purchase or refinance investment nonresidential properties. This includes office buildings and other facilities rented or leased to unrelated parties, as well as farmland and multifamily properties. The primary risk associated with income producing commercial mortgage loans is the ability of the income-producing property that collateralizes the loan to produce adequate cash flow to service the debt. While these loans are collateralized by real property in an effort to mitigate risk, it is possible the liquidation of collateral will not fully satisfy the obligation.

● Construction - Construction loans consist of loans to finance land for development of commercial or residential real property and construction of multifamily apartments or other commercial properties. These loans are highly dependent on the supply and demand for commercial real estate as well as the demand for newly constructed residential homes and lots acquired for development. Deterioration in demand could result in decreased collateral values, which could make repayments of outstanding loans difficult for customers.

● Commercial business - Commercial business loans consist of loans or lines of credit to finance accounts receivable, inventory or other general business needs, business credit cards, and lease financing agreements for equipment, vehicles, or other assets. The primary risk associated with commercial and industrial and lease financing loans is the ability of borrowers to achieve business results consistent with those projected at origination. Failure to achieve these projections presents risk the borrower will be unable to service the debt consistent with the contractual terms of the loan.

Consumer loans

● Real estate - Residential mortgages consist of loans to purchase or refinance the borrower’s primary dwelling, second residence or vacation home and are often secured by 1-4 family residential property. Significant and rapid declines in real estate values can result in borrowers having debt levels in excess of the current market value of the collateral.

● Home equity – Home equity loans consist of home equity lines of credit and other lines of credit secured by first or second liens on the borrower’s primary residence. These loans are secured by both senior and junior liens on the residential real estate and are particularly susceptible to declining collateral values. This risk is elevated for loans secured by junior lines as a substantial decline in value could render the junior lien position effectively unsecured.

● Construction - Construction loans consist of loans to construct a borrower’s primary or secondary residence or vacant land upon which the owner intends to construct a dwelling at a future date. These loans are typically secured by undeveloped or partially developed land in anticipation of completing construction of a 1-4 family residential property. There is risk these construction and development projects can experience delays and cost overruns exceeding the borrower’s financial ability to complete the project. Such cost overruns can result in foreclosure of partially completed and unmarketable collateral.

● Other - Consumer loans consist of loans to finance unsecured home improvements, student loans, automobiles and revolving lines of credit that can be secured or unsecured. The value of the underlying collateral within this class is at risk of potential rapid depreciation which could result in unpaid balances in excess of the collateral.

For all loan pools, the Company uses a lifetime probability of default and loss given default modeling approach to estimate the allowance for credit losses on loans. This method uses historical correlations between default experience and the age of loans to forecast defaults and losses, assuming that a loan in a pool shares similar risk characteristics such as loan product type, risk rating and loan age, and demonstrates similar default characteristics as other loans in that pool, as the loan progresses through its lifecycle. The Company calculates lifetime probability of default and loss given default rates based on historical loss experience, which is used to calculate expected losses based on the pool’s loss rate and the age of loans in the pool. Management believes that the Company’s historical loss experience provides the best basis for its assessment of expected credit losses to determine the allowance for credit losses. The Company uses its own internal data to measure historical credit loss experience within the pools with similar risk characteristics over an economic cycle. The probability of default and loss given default method also includes assumptions of observed migration over the lifetime of the underlying loan data.

Management also considers further adjustments to historical loss information for current conditions and reasonable and supportable forecasts that differ from the conditions that exist for the period over which historical information is evaluated as well as other changes in qualitative factors not inherently considered in the quantitative analyses. The qualitative categories and the measurements used to quantify the risks within each of these categories are subjectively selected by management, but measured by objective measurements period over period. The data for each measurement may be obtained from internal or external sources. The current period measurements are evaluated and assigned a factor commensurate with the current level of risk relative to past measurements over time. The resulting qualitative adjustments are applied to the relevant collectively evaluated loan pools. These adjustments are based upon quarterly trend assessments in certain economic factors as well as associate retention and turnover, portfolio concentrations, and growth characteristics. The qualitative analysis increases or decreases the allowance allocation for each loan pool based on the assessment of factors described above.

Loans that do not share similar risk characteristics with the collectively evaluated pools are evaluated on an individual basis and are excluded from the collectively evaluated loan pools. Individual loan evaluations are generally performed for impaired loans, which includes nonaccrual loans and loans modified in a troubled debt restructuring (“TDR”). Such loans are evaluated for credit losses based on either discounted cash flows or the fair value of collateral. The Company has elected the practical expedient under ASC 326 to estimate expected credit losses based on the fair value of collateral, which considers selling costs in the event sale of the collateral is expected. Loans for which terms have been modified in a TDR are evaluated using these same individual evaluation methods. In the event the discounted cash flow method is used for a TDR, the original interest rate is used to discount expected cash flows.

While the Company’s policies and procedures used to estimate the allowance for credit losses, as well as the resultant provision for credit losses charged to income, are considered adequate by management and are reviewed periodically by regulators, model validators and internal audit, they are necessarily approximate and imprecise. There are factors beyond the Company’s control, such as changes in projected economic conditions, real estate markets or particular industry conditions which may materially impact asset quality and the adequacy of the allowance for credit losses and thus the resulting provision for credit losses.

Accrued Interest Receivable

Accrued interest receivable related to loans totaled $7.5 million at September 30, 2022 and was reported in accrued interest receivable on the consolidated balance sheets. The Company elected not to measure an allowance for credit losses for accrued interest receivable and instead elected to reverse interest income on loans or securities that are placed on nonaccrual status, which is generally when the instrument is 90 days past due, or earlier if the Company believes the collection of interest is doubtful. The Company has concluded that this policy results in the timely reversal of uncollectable interest.

Unfunded Commitments

Effective with the adoption of CECL, the Company estimates expected credit losses on commitments to extend credit over the contractual period in which the Company is exposed to credit risk on the underlying commitments, unless the obligation is unconditionally cancelable by the Company. The allowance for off-balance sheet credit exposures, which is reflected within other liabilities on the consolidated balance sheet, is adjusted for as an increase or decrease to the provision for credit losses. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The allowance is calculated using the same aggregate reserve rates calculated for the funded portion of loans at the portfolio level applied to the amount of commitments expected to fund.

The Company’s CECL allowances will fluctuate over time due to macroeconomic conditions and forecasts as well as the size and composition of the loan portfolios.

Newly Issued, But Not Yet Effective Accounting Standards

In March 2022, the FASB amended the Receivables–Troubled Debt Restructuring by Creditors subtopic and Financial Instruments–Credit Losses subtopic to the Accounting Standards Codification. The amendments eliminate the accounting guidance for TDRs by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. In addition, for public business entities, the amendments require disclosure of current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20. The amendments are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption of the amendments is permitted if ASU 2016-13 has been adopted, including adoption in an interim period. The Company does not expect these amendments to have a material effect on its financial statements.
