This allowance evaluation process is also applied to troubled debt restructurings 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 and environmental conditions, among other factors.
