The Company is evaluating the customer data that was affected and is conducting notifications as required by applicable federal and state laws and regulatory guidance. The Company has been, and continues to be, in communication with relevant banking and financial regulators regarding the incident.
The Company has taken, and continues to take, actions designed to contain and remediate the incident.
