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. </p> | |

<p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:left; margin-top:11pt; margin-bottom:0pt; "> <span style="font-style:italic; ">Risks and Uncertainties</span></p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">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.</p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">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.</p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">The Bank makes loans to individuals and businesses in the Upstate, Midlands, and Lowcountry regions of South Carolina as well as the Triangle and Triad 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, 2020 and 2019, real estate loans represented 84.6% and 82.8%, respectively, of total loans. However, borrowers’ ability to repay their loans is not dependent upon any specific economic sector.</p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">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.</p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:12pt; text-align:justify; margin-bottom:0pt; "/> <div> <div style="width:100%; clear:both;"> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:center; ">76</p> </div><hr style="border-top:2.0pt solid #808080;"/><div style="page-break-after:always;"/> </div> <p style="font-weight:bold; font-size:10pt; font-family:Arial, Helvetica, sans-serif"><a href="#t001">Table of Contents</a></p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">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. </p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">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. </p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">As of December 31, 2020, 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. </p> <p style="font-family:Arial, Helvetica, sans-serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">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, 2020, the $15.0 million line was unused. </p> | |
