David Becher, a fellow at Drexel University's LeBow College of Business Center for Corporate Governance and associate professor of finance, commented on an article about the sale of Harleysville National Corp. to Buffalo’s First Niagara Financial Corp. Becher said that depending on the issues involved and how a bank responds, a regulatory action could spell certain death.“If a bank is ordered to raise cash, that could be impossible for some,” Becher said. “But they can change board members or executives and improve the lending portfolio.”
