Professor William Volz of the School of Business Administration is quoted in a story about fraud charges filed against Delphi Corp., the auto parts supplier. The suit, filed by several institutional investors, claims that Delphi used business and accounting practices that hid growing financial problems. Volz pointed out that investors rely on the accuracy of a company's financial reports, and "when an enterprise's financial statements are sullied, it's not a stain that goes away quickly."
