Shareholder demand letter
On April 16, 2009, Allstate received the Service Employees International Union ("SEIU") Pension Plans Master Trust's shareholder demand for board action concerning the Company's past executive compensation practices. The Company believes that as many as 28 other companies may have received similar letters from the SEIU. The SEIU correspondence has been referred to Allstate's Board of Directors for its consideration and disposition.
