The nature of the process by which the Bank determines the appropriate allowance for loan losses requires the exercise of considerable judgment. This allowance evaluation process is also applied to TDRs since they are considered to be impaired loans. The allowance for loan losses and the reserve for off-balance sheet credit commitments are significant estimates that can and do change based on management’s process in analyzing the loan portfolio and on management’s assumptions about specific borrowers, underlying collateral, and applicable economic, market and environmental conditions, among other factors. Although the Company took steps to incorporate the impact of the COVID- 19 19 A TDR is a formal modification of the terms of a loan when the lender, for economic or legal reasons related to the borrower’s financial difficulties, grants a concession to the borrower.
