Actual results could differ from those estimates.

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 the Company’s business, financial condition and results of operations is currently uncertain and the timing and pace of recovery will depend on various developments and other factors, including, among others, the duration and scope of the pandemic, as well as governmental, regulatory and private sector responses to the pandemic, and the associated impacts on the economy, financial markets and our clients, employees and vendors.</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; ">8</p> </div><hr style="border-top:2.0pt solid #808080;"/><div style="page-break-after:always;"/> </div> <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 <span style="-sec-ix-hidden:Fact_455">50</span> basis points, followed by an additional reduction of <span style="-sec-ix-hidden:Fact_456">100</span> 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 September 30, 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 September 30, 2020, the $15.0 million line was unused. </p>
