EXPLANATORY NOTE

 

This Amendment No. 6 to Schedule 13D (“Amendment No. 6”) relates to the Common Shares of Beneficial Interest without par value (the “Common Shares”) of Western Asset/Claymore Inflation-Linked Securities and Income Fund (the “Issuer”).  This Amendment No. 6 is filed to amend and supplement the Items set forth below of the Reporting Persons’ Schedule 13D previously filed with the Securities and Exchange Commission on January 3, 2006, as amended on April 19, 2006, June 18, 2008, July 7, 2008, July 17, 2008 and October 17, 2008.

During the past sixty days, Cascade acquired 26,371 Common Shares pursuant to a dividend reinvestment plan of the Issuer on the dates and at the prices and amounts set forth below.
