Lehman Brothers Holdings Inc. (the “Registrant”) is not timely filing its Quarterly Report on Form 10-Q for the fiscal quarter ended May 31, 2011 (“Form 10-Q”).  The principal reasons for the Registrant’s inability to file at this time are as follows: (1) the filing by the Registrant of a voluntary petition for relief under Chapter 11 of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of New York (the “Court”) on September 15, 2008 in a jointly administered proceeding named In re Lehman Brothers Holdings Inc., et. al. under Case Number 08-13555; (2) the commencement of various administrative or civil rehabilitation proceedings of subsidiaries comprising significant parts of the Registrant’s European and Asian businesses; (3) the sale since September 15, 2008 of significant businesses comprising the Registrant’s historical business; and (4) the completion on May 4, 2009 of the transfer to Neuberger Berman Group LLC of the Registrant's investment management business, as described in its Current Report on Form 8-K filed with the Commission on May 4, 2009.  As a result of these developments, the Registrant is currently unable to complete the preparation of its consolidated financial statements for such period in as much as it currently has neither access to major components of its internal systems nor the ability to prepare its consolidated financial statements and the remainder of the report, with all the required disclosures, to have them properly certified by its current executive officers, and have them reviewed by its independent auditors.  The Registrant will not be in a position to file by the fifth calendar day following the required filing date, July 15, 2011, as prescribed in Rule 12b-25.
