 PNC's stock price lost roughly half of its overall value throughout 2001 and at shareholders' meetings during that time, shareholders began to demand that Rohr resign from his position.In the wake of that scandal, Rohr led an overhaul of PNC's risk management systems that would ultimately help position PNC well for the 2008 financial crisis to come, and his reforms helped boost the performance of PNC's stock.By 2003, PNC was in acquisition mode, picking up United National Bancorp, expanding its presence in Eastern Pennsylvania and Central New Jersey.
