While there continues to be great uncertainty related to COVID-19 on our borrowers and communities, we have recognized improvements in employment and gross domestic product which are key indicators utilized in our forecasting for our allowance calculations. The impact of fiscal stimulus, including direct payments to individuals, ongoing increased unemployment benefits, as well as the various government-sponsored loan programs, was also considered in our qualitative adjustments. Since PPP loans are guaranteed by the Small Business Administration (SBA), they have minimal impact on the allowance for credit losses.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">All classes of loans, including loans acquired with deteriorated credit quality, are generally placed on non-accrual status when scheduled principal or interest payments are past due for 90 days or more or when the borrower’s ability to repay becomes doubtful. For purchased loans, the determination is made at the time of acquisition as well as over the life of the loan. Uncollected accrued interest for each class of loans is reversed against income at the time a loan is placed on non-accrual. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. All classes of loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Loans are typically charged-off at 180 days past due, or earlier if deemed uncollectible. Exceptions to the non-accrual and charge-off policies are made when the loan is well secured and in the process of collection.</span></div>
