Actual results could differ from those estimates, and such differences could be material.</span></p> <p style="font-family: "Times New Roman"; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"> </p> <p style="font-family: "Times New Roman"; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><span style="color:#000000;">Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses. While management uses available information to recognize credit losses on loans, future additions to the allowance <em style="font: inherit;"> may </em>be necessary based on changes in economic conditions, changes in conditions of our borrowers’ industries or changes in the condition of individual borrowers. As described below under “Accounting Standards Adopted in <em style="font: inherit;">2023,”</em> the Company adopted Accounting Standards Update (“ASU”) <em style="font: inherit;">2016</em>-<em style="font: inherit;">13</em> effective <em style="font: inherit;"> January 1, 2023, </em>which changed how the Company accounts for the allowance for credit losses. In addition, regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for credit losses. Such agencies <em style="font: inherit;"> may </em>require the Company to recognize additions to the allowance based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the allowance for credit losses <em style="font: inherit;"> may </em>change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated.</span></p> <p style="font-family: "Times New Roman"; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"> </p> <p style="font-family: "Times New Roman"; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><span style="color:#000000;">Other estimates that are susceptible to significant change in the near term relate to the allowance for off-balance sheet credit losses, the fair value of stock-based compensation awards, the determination of other-than-temporary impairments of securities, and the fair value of financial instruments and goodwill. Rapidly changing inflation rates and rising interest rates have made certain estimates more challenging, including those discussed above.</span></p> <p style="font-family: "Times New Roman"; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"> </p> <p style="font-family: "Times New Roman"; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"></p>
