Human-readable explanation

The model produced risk category LOW, trust score 81.0, and confidence score 1.0. The principal model factors increasing modeled risk were: New payment corridor. The principal model factors reducing modeled risk were: Established device relationship, Established customer relationship, Established counterparty relationship. This explanation describes model evidence only and does not constitute an institutional transaction decision.
