Description Of Bank's Loan Grading Process | The Bank''s loan grading process is as follows:§ All loans are assigned a loan grade at the time of origination by the relationship manager. Typically, a loan is assigned a loan grade of pass at origination. § Loans greater than or equal to $500 thousand are reviewed by the Bank''s internal loan review department within 90 days of origination. § Loan relationships greater than or equal to $1 million are reviewed annually by the internal loan review department. § The Bank''s internal loan review department samples approximately 25 percent of all other loans less than $1 million on an annual basis for review. § If a loan is delinquent 60 days or more or a pattern of delinquency exists the loan will be selected for review. § Generally, all loans on the Bank''s internal watchlist are reviewed annually by internal loan review. § The Bank also contracts with an independent third party to perform loan reviews. This external party reviews approximately 40 percent of the Bank''s loan portfolio annually. |
