* Because the common stock of Duquesne Light Holdings, Inc. has been acquired in a merger and deregistered, and is no longer publicly held, employee salary deferral contributions under the Duquesne Light Company 401(k) Retirement Savings Plan for IBEW Represented Employees may no longer be invested in the common stock. Therefore, pursuant to SEC Release 33-6188, plan interests are exempt from registration and 11-Ks no longer need to be filed.
