Loan Portfolio Credit Exposure

In the following tables, consumer loans are generally assigned a risk grade similar to the classifications described above; however, upon reaching 90 days and 120 days past due, they are generally downgraded to Substandard and Loss, respectively, in accordance with the FFIEC Retail Credit Classification Policy. Additionally, in accordance with Interagency Supervisory Guidance, the risk grade classifications of consumer loans (consumer mortgages and home equity lines) secured by junior liens on 1-4 family residential properties also consider available information on the payment status of the associated senior lien with other financial institutions.
