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 for loans and investment securities held to maturity, fair value of financial instruments, fair values of assets and liabilities acquired in business combinations, evaluating impairment of investment securities, goodwill and other intangible impairment tests and valuation of deferred tax assets.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"><span style="white-space:pre-wrap;">In connection with the determination of the allowance for credit losses, management has identified specific loans as well as adopted a policy of providing amounts for loan valuation purposes which are not identified with any specific loan but are derived from models based on macroeconomic factors and forecasts. Management believes that the allowance for credit losses is appropriate. While management uses available information to recognize losses on loans, future additions or reductions to the allowance for credit losses may be necessary based on changes in economic forecasts. In addition, regulatory agencies, as an integral part of the examination process, periodically review the banking subsidiary’s allowance for credit losses. Such agencies may require additions to the allowance for credit losses based on their judgments about information available to them at the time of their examination. </span> </p>

Although the Bank has a diversified loan portfolio, a substantial portion of their borrowers’ abilities to honor their contracts is dependent upon economic conditions within South Carolina, North Carolina, Florida, Alabama, Virginia, Georgia and the surrounding regions.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;">The Company considers concentrations of credit to exist when, pursuant to regulatory guidelines, the amounts loaned to a multiple number of borrowers engaged in similar business activities which would cause them to be similarly impacted by general economic conditions represents 25% of total Tier 1 capital plus regulatory adjusted allowance for credit losses of the Company, or $1.2 billion at December <span style="white-space:pre-wrap;">31, 2023. Based on this criteria, we </span>had eight such credit concentrations at December 31, 2023, including loans to lessors of nonresidential buildings (except mini warehouses) of $6.2 billion, loans secured by owner occupied office buildings (including medical office buildings) of $1.9 billion, loans secured by owner occupied nonresidential buildings (excluding office buildings) of $1.8 billion, loans to lessors of residential buildings (investment properties and multi-family) of $2.4 billion, loans secured by 1st mortgage 1-4 family owner occupied residential property (including condos and home equity lines) of $8.8 billion, loans secured by jumbo (original loans greater than $726,200) 1st mortgage 1-4 family owner occupied residential property of $2.6 billion, loans secured by business assets including accounts receivable, inventory and equipment of $2.2 billion, and loans to consumers secured by non-real estate of $1.2<span style="white-space:pre-wrap;"> billion. The risk for these loans and for all loans is managed collectively through the use of credit underwriting practices developed and updated over time. The loss estimate for these loans is determined using our standard ACL methodology.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"><span style="white-space:pre-wrap;">With some financial institutions adopting CECL in the first quarter of 2020, banking regulators established new guidelines for calculating credit concentrations. Banking regulators set the guidelines for construction, land development and other land loans to total less than 100% of total Tier 1 capital less modified CECL transitional amount plus ACL (CDL concentration ratio) and for total commercial real estate loans (construction, land development and other land loans along with other non-owner occupied commercial real estate and multifamily loans) to total less than 300% of total Tier 1 capital less modified CECL transitional amount plus ACL (CRE concentration ratio). Both ratios are calculated by dividing certain types of loan balances for each of the two categories by the Bank’s total Tier 1 capital less modified CECL transitional amount plus ACL. At December 31, 2023 and 2022, the Bank’s CDL concentration ratio </span>was 59.7% and 64.8%, respectively, and its CRE concentration ratio was 236.5% and 249.0%<span style="white-space:pre-wrap;">, respectively. As of December 31, 2023, the Bank was below the established regulatory guidelines and we monitor these two ratios as part of our concentration management processes.</span></p>
