Additionally, in accordance with the Interagency Supervisory Guidance on Allowance for Loan and Lease Losses Estimation Practices for Loans and Lines of Credit Secured by Junior Liens on 1-4 Family Residential Properties, the risk grade classifications of retail loans (home equity lines and consumer mortgages) 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.
