Ernst & Young new defendant in Lehman suit-report

* Class-action lawsuit

* Ernst added as defendant after examiner's report

NEW YORK, April 23 (Reuters) - Ernst & Young LLP, the auditor for Lehman Brothers Holdings Inc LEHMQ.PK, was added as a defendant to an investor lawsuit seeking to recover money from former executives and underwriters, Bloomberg News said, citing a court document filed on Friday.

The document was not immediately available online. An Ernst & Young spokesman did not immediately return a call seeking comment. A lawyer for a group of pension funds that are leading the lawsuit also did not immediately return a call.

According to the article Ernst was added to the class-action lawsuit for failing to disclose Repo 105 transactions, making false statements about liquidity and overstating real estate values. The new claims reflect findings from a report filed last month by Lehman bankruptcy examiner Anton Valukas, it said.

The lawsuit was originally filed in June 2008. It then alleged that Lehman was too slow to write down mortgage-related and other risky debt, and thus overstated its financial health and inflated its stock price. Former Lehman Chief Executive Richard Fuld was among the named defendants.

Lehman filed for bankruptcy on Sept. 15, 2008. The bankruptcy remains by far the largest in U.S. history.

The case is In re Lehman Brothers Equity/Debt Securities Litigation, U.S. District Court, Southern District of New York, No. 08-05523. (Reporting by Jonathan Stempel; editing by Carol Bishopric)
