Accounting Policies [Abstract] |
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 periods ended September 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. 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, 2024 as filed with the U.S. Securities and Exchange Commission (“SEC”) on March 3, 2025. 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. Risk 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. There were several notable bank failures in 2023, driven primarily by liquidity challenges as depositors rapidly withdrew funds. These failures were exacerbated by the impact of rising interest rates, which left affected banks unable to sell long-term investment securities without incurring significant losses. In response, regulators took steps to stabilize the banking system, including ensuring that losses to the Deposit Insurance Fund used to support uninsured depositors would be recovered through a special assessment on banks, as mandated by law. While the banking disruptions seen in 2023 have largely stabilized, the financial environment remains uncertain, shaped by ongoing inflationary pressures, and persistent concerns around commercial real estate values and refinancing risks. In late 2024, the Federal Reserve began lowering interest rates in response to easing inflation and slowing growth. While lower rates can support loan demand, they may also compress net interest margins. The Federal Reserve is also continuing balance sheet reduction, contributing to some funding and market volatility. The long-term impact of these developments on the economy, financial institutions, and regulatory frameworks remains uncertain. 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 the Company to changes with respect to the valuation of assets, the amount of required credit 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 September 30, 2025 and December 31, 2024, real estate loans represented 83.0% and 83.5%, respectively, of total loans. However, borrowers’ ability to repay their loans is not dependent upon any specific economic sector. As of September 30, 2025, 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, our reported and regulatory capital ratios could be adversely impacted by future 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 September 30, 2025, the $15.0 million line was unused. 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, and valuation of deferred tax assets. During the first quarter of 2025, the Company refined its methodology for estimating the allowance for credit losses (“ACL”) on loans by transitioning from a lifetime probability of default and loss given default model to a discounted cash flow (“DCF”) approach. The Company transitioned to the DCF method as it allows for a better estimation of credit losses through customization among the various inputs by loan segmentation. The DCF model uses regression techniques that relate one or more economic factors to the default rate of various portfolios to build reasonable and supportable forecasts to estimate future losses. The Company determined that the national gross domestic product and unemployment rate were the two economic factors which had the greatest correlation to historical performance for use in the forecasted portion of the model. In addition, the transition to the DCF model allowed the Company to reduce its reliance on qualitative factors and to analyze them on a more granular level, such as by segment. The refinement represents a change in accounting estimate under ASC Topic 250, Accounting Changes and Error Corrections, with prospective application beginning in the period of change. This change in accounting estimate did not have a material effect on the Company’s financial statements. 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. Newly Issued, But Not Yet Effective Accounting Standards In November 2024, the FASB amended the Income Statement – Reporting Comprehensive Income topic in the Accounting Standards Codification to require public companies to disclose, in interim and annual reporting periods, additional information about certain expenses in the notes to the financial statements. The amendments are effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company will apply the amendments retrospectively to all prior periods presented in the financial statements. The Company does not expect these amendments to have a material effect on its financial statements.
