The case was the last significant lawsuit against Ernst & Young over Lehman, according to a spokeswoman for the accounting firm. "After many years of costly litigation, we are pleased to put this matter behind us, with no findings of wrongdoing by EY or any of its professionals," the firm said in a statement. According to the complaint, Ernst approved the "surreptitious" removal of tens of billions of dollars of debt from Lehman's balance sheet to make the investment bank appear less indebted at the close of financial quarters. Lehman filed for bankruptcy on Sept. 15, 2008, helping to trigger the global financial crisis. Once the fourth-largest U.S. investment bank, Lehman held large quantities of risky subprime mortgage securities. The complaint alleged that, for more than seven years before Lehman's bankruptcy, the bank made use of transactions known as "Repo 105s," short-term financing that temporarily moved as much as $50 billion from its balance sheet.
