analyses of actual charge-offs tracked back in time to the triggering event for the eventual loss . in addition , various qualitative factors are considered , including specific terms and conditions of loans and leases , underwriting standards , delinquency statistics , industry concentration , overall exposure to a single customer , adequacy of collateral , the dependence on collateral , and results of internal loan review , including a borrower 's perceived financial and management strengths , the amounts and timing of the present value of future cash flows , and the access to additional funds . it should be noted that this evaluation is inherently subjective as it requires material estimates , including , among others , expected default probabilities , the amounts and timing of expected cash flows on impaired loans and leases , the value of collateral , estimated losses on consumer loans and residential mortgages and the relevance of historical loss experience . the process also considers economic conditions and inherent risks in the loan and lease portfolio . all of these factors may be susceptible to significant change . to the extent actual outcomes differ from
