On May 28, the OCC announced that it will expand the organization, functions and responsibilities of its large bank lead expert program to improve horizontal perspective and analysis, systemic risk identification and resource prioritization. The OCC will establish a formal rotation program for all examiners to provide them with broader perspectives. The OCC will also formalize an enterprise risk management framework.
