Data as of · sourced from FFIEC call reports. How we update
A relative risk score, not a calibrated probability: it ranks this bank against every other filer. Model AUC 0.988 (v20261005_114304). Trained on credit-driven community-bank failures, it carries little signal for interest-rate or deposit-flight risk, and its accuracy above roughly $10B in assets is not established, so a low score is not evidence of safety. See the methodology. This is not investment advice or a credit rating.
