Accordingly, they do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial position and the results of operations for the interim periods presented have been included.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 10pt 27pt;">The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Amounts subject to significant estimates are items such as the allowance for loan losses and lending related commitments, the fair value of financial instruments, other-than-temporary impairments of investment securities, and the valuations of goodwill and intangible assets, and servicing assets. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27pt;">These unaudited consolidated financial statements should be read in conjunction with the Corporation’s filings with the Securities and Exchange Commission (including our Annual Report on Form 10-K for the year ended December 31, 2019) and, subsequently filed quarterly reports on Form 10-Q and current reports on Form 8-K that update or provide information in addition to the information included in Form 10-K and Form 10-Q filings, if any. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27pt;"><span style="margin-bottom:12pt;margin-left:0pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27pt;">Certain prior period amounts have been reclassified to conform with current period presentation.

The continued spread of COVID-19 throughout the U.S. has caused significant disruption in the U.S. economy and has disrupted banking and other financial activity in the areas in which the Corporation operates.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27.35pt;"><span style="margin-bottom:12pt;margin-left:0pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27.35pt;">Although the Corporation’s current estimates contemplate current conditions and how we expect them to change in the future, due to the prolonged impact that the COVID-19 has had on financial markets and the economy both locally and nationally, it is reasonably possible that this could materially affect these significant estimates and the Corporation’s results of operations and financial condition. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27.35pt;"><span style="margin-bottom:12pt;margin-left:0pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27.35pt;">The Corporation has continued to work with customers directly affected by COVID-19 since it was declared a pandemic, to provide short-term assistance in accordance with regulatory guidelines. While the Corporation has factored the ongoing impacts of COVID-19 into the allowance for loan and lease losses calculation as of September 30, 2020, should economic conditions continue to worsen, the Corporation could experience further increases in its required allowance for loan and lease losses and record additional provision for loan loss expense. It is possible that the Corporation’s asset quality measures could worsen at future measurement periods due to the continuing effects of COVID-19 may have on borrowers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27.35pt;">COVID-19 could cause a further and sustained decline in the Corporation’s stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, cause us to perform goodwill and intangible asset impairment tests and result in an impairment charge being recorded for that period. In the event that the Corporation concludes that all or a portion of its goodwill or intangible assets are impaired, a </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27.35pt;">non-cash charge for the amount of such impairment would be recorded to earnings.

It contained substantial tax and spending provisions intended to address the impact of the COVID-19 pandemic. The CARES Act included the Paycheck Protection Program (the “PPP”), a $349 billion program designed to aid small and medium sized businesses through federally guaranteed loans distributed through banks. The Paycheck Protection Program and Health Care Enhancement Act (the “PPP/HCEA Act”) was signed into law on April 24, 2020. The PPP/HCEA Act authorized an additional $310 billion of funding under the CARES Act for </span>PPP<span style="background-color:#ffffff;"> loans among other provisions. On July 4, 2020, legislation was passed to extend the application period for the </span>PPP<span style="background-color:#ffffff;"> program through August 8, 2020. These loans are intended to cover eight weeks of payroll and other permitted expenses to help those businesses remain viable.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 0pt 27.35pt;"><span style="margin-left:0pt;visibility:hidden;"></span></p>
