[1] Unrated loans consist of performing loans which did not exhibit any negative characteristics which would require the loan to be evaluated, or fell below the dollar threshold requiring review and was not one of the loans otherwise selected in ongoing portfolio evaluation The scope of the Bank’s loan review policy encompasses commercial and construction loans and leases which singly or in the aggregate in the case of loans with related borrowers, equal or exceed $3,000,000. It is present Bank policy that a minimum of 60% of the loan portfolio be reviewed every eighteen months. The loan portfolio review coverage was approximately 70% at December 31, 2013 and approximately 69% at December 31, 2012. This review is performed by the loan review department, which is independent of the loan department and reports directly to the audit committee. All classified loans are reviewed by the independent loan review function of the Bank. Potential problem loans which are identified by either the independent loan review department or line management are also reviewed. All loans are subject to review by their relationship manager and senior loan personnel. Also, many of the Bank’s loans are relatively short term, and are subject to reconsideration with a full review in loan committee between one and three years
