The chief operating decision maker (CODM) at DTE Energy is the Financial Objectives committee, which is comprised of the Chief Executive Officer, Chief Financial Officer, and other executive leaders of DTE Energy. The CODM at DTE Electric is comprised of the Chief Executive Officer and Chief Financial Officer.
