The Bank's loan risk rating and review policy establishes requirements for the annual review of commercial real estate and commercial and industrial loans. The requirements include details of the scope of coverage and selection process based on loan-type and risk rating.

Residential mortgage loans, revolving home equity lines and other consumer loans are initially evaluated utilizing the borrower’s credit score. A credit score is a tool used in the Bank’s loan approval process, and a minimum score of 680 is generally required for new loans. Credit scores for each borrower are updated at least annually.
