Former Pennsylvania Gov. Tom Ridge is stepping down from the boards of Exelon (NYSE:EXC) and Peco Energy to pursue a business opportunity with PricewaterhouseCoopers.

The companies disclosed the change late Friday in a joint filing with the Securities and Exchange Commission. PwC serves as independent accountant for Exelon and Peco.

Ridge, for his part, leaves a hole on two of Exelon's board committees: Energy Delivery Oversight and Risk Oversight. Peco is one of three Exelon utility subsidiaries and key to its long-term growth strategy.
