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, derivatives, real estate acquired in settlement of loans, fair value of financial instruments, evaluating investment securities for credit impairment and valuation of deferred tax assets.</p>

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 three significant bank failures in the first five months of 2023, primarily due to the failed banks’ lack of liquidity as depositors sought to withdraw their deposits. Due to rising interest rates, the failed banks were unable to sell investment securities held to meet liquidity needs without realizing substantial losses. As a result of the recent bank failures and in an effort to strengthen public confidence in the banking system and protect depositors, regulators announced that any losses to the Deposit Insurance Fund to support uninsured depositors will be recovered by a special assessment on banks, as required by law, which has and could continue to increase the cost of our FDIC insurance assessments. The continued impact of these bank failures on the economy, financial institutions and their depositors, as well as any governmental regulatory responses or actions resulting from the same, is difficult to predict at this time.</p> <p style="font: 10pt Arial, Helvetica, Sans-Serif; text-align: justify">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 credit loss allowance and operating restrictions resulting from the regulators’ judgments based on information available to them at the time of their examinations.</p> <p style="font: 10pt Arial, Helvetica, Sans-Serif; text-align: justify">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.

CY2023	us-gaap	Description Of Capital Requirements On Trust Assets DescriptionOfCapitalRequirementsOnTrustAssets	The capital rules require banks and bank holding companies to maintain a minimum total risked-based capital ratio of at least 8%, a total Tier 1 capital ratio of at least 6%, a minimum common equity Tier 1 capital ratio of at least 4.5%, and a leverage ratio of at least 4%. Bank holding companies and banks are also required to hold a capital conservation buffer of common equity Tier 1 capital of 2.5% to avoid limitations on capital distributions and discretionary executive compensation payments. The capital conservation buffer was phased in incrementally over time, becoming fully effective on January 1, 2019, and consists of an additional amount of common equity equal to 2.5% of risk-weighted assets.
