[1] * Ratings are generally assigned to consumer and residential mortgage loans on a "pass" or "fail" basis, where "fail" results in a substandard classification. Commercial loans, both secured by real estate or other assets or unsecured, are analyzed in accordance with an analytical matrix codified in the Bank's loan policy that produces a risk rating as described below. Risk 1 is unquestioned credit quality for any credit product. Loans are secured by cash and near cash collateral with immediate access to proceeds. Risk 2 is very low risk with strong credit and repayment sources. Borrower is well capitalized in a stable industry, financial ratios exceed peers and financial trends are positive. Risk 3 is very favorable risk with highly adequate credit strength and repayment sources. Borrower has good overall financial condition and adequate capitalization. Risk 4 is acceptable, average risk with adequate credit strength and repayment sources. Collateral positions must be within Bank policies. Risk 5 or "Special Mention," also known as "watch," has potential weakness that deserves Management's close attention. This risk includes loans where the borrower has developed financial uncertainties or the borrower is resolving the financial uncertainties. Bank credits have been secured or negotiations will be ongoing to secure further collateral. Risk 6 or "Substandard" loans are inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged. This risk category contains loans that exhibit a weakening of the borrower's credit strength with limited credit access and all non-performing loans. Risk 7 or "Doubtful" loans are significantly under protected by the current net worth and paying capacity of the borrower or of the collateral pledged. This risk category contains loans that are likely to experience a loss of some magnitude, but where the amount of the expected loss is not known with enough certainty to allow for an accurate calculation of a loss amount for charge-off. This category is considered to be temporary until a charge-off amount can be reasonably determined.
