Wholesale loans |
Financing Receivable Credit Quality Indicators | Wholesale Loans The Bank has in place a process of grading each borrower according to its financial health and the performance of its business and each borrower is graded as pass/labeled/impaired. Wholesale loans that are not impaired are disclosed as pass or labeled and considered to be performing. Labeled loans are those with evidence of weakness where such exposures indicate deteriorating trends which if not corrected could adversely impact repayment of the obligations. The Bank’s model assesses the overall risk over four major categories – industry risk, business risk, management risk and financial risk. The inputs in each of the categories are combined to provide an aggregate numerical rating, which is a function of the aggregate weighted scores based on the assessment under each of these four risk categories.
