Estimates are susceptible to material changes as a result of changes in facts and circumstances. Facts and circumstances which could affect these judgments include, but are <em style="font: inherit;">not</em> limited to, changes in interest rates, changes in the performance of the economy, including pandemic-related changes, and changes in the financial condition of borrowers.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Bancorp’s accounting policies are fundamental to understanding management’s discussion and analysis of our results of operations and financial condition. At <em style="font: inherit;"> June 30, 2021 </em>and <em style="font: inherit;"> December 31, 2020, </em>the accounting policy considered the most critical in preparing Bancorp’s consolidated financial statements is the determination of the ACL on loans.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Effective <em style="font: inherit;"> January 1, 2020, </em>Bancorp adopted ASC <em style="font: inherit;">326</em> “<i>Financial Instruments </i>–<i> Credit Losses,</i>” which created material changes to Bancorp’s existing critical accounting policy that existed at <em style="font: inherit;"> December 31, 2019. </em>Accounting policies relating to credit losses for investment securities, loans and off-balance sheet credit exposures reflect the current accounting policies required by this ASC.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">The ACL on loans is established through credit loss expense charged to current earnings. The amount maintained in the ACL reflects management’s estimate of the net amount <em style="font: inherit;">not</em> expected to be collected on the loan portfolio at the balance sheet date over the life of the loan. The ACL is comprised of specific reserves assigned to certain loans that do <em style="font: inherit;">not</em> share general risk characteristics and general reserves on pools of loans that do share general risk characteristics. Factors contributing to the determination of specific reserves include the creditworthiness of the borrower and more specifically, changes in the expected future receipt of principal and interest payments and/or in the value of pledged collateral. A specific reserve is recorded when the carrying amount of the loan exceeds the discounted estimated cash flows using the loan’s initial effective interest rate or the fair value of the collateral for certain collateral-dependent loans.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p> <p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">For purposes of establishing the general reserve, Bancorp stratifies the loan portfolio into homogeneous groups of loans that possess similar loss potential characteristics and calculates the net amount expected to be collected over the life of the loans to estimate the credit losses in the loan portfolio. Bancorp’s methodologies for estimating the ACL on loans consider available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts.</p> <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"> </p>
