       The U.S.&amp;#160;Federal income tax jurisdiction is the
       Company&amp;#8217;s major tax jurisdiction. The statutes of
       limitations for the Company&amp;#8217;s U.S.&amp;#160;Federal income tax
       returns for the years ended December&amp;#160;31, 2006 through 2009
       are open as of April&amp;#160;1, 2011. The Internal Revenue Service
       (IRS) is expected to complete its audit of the Company&amp;#8217;s
       2006 and 2007 U.S.&amp;#160;Federal income tax returns during the
       second quarter of 2011, and the related statutes of limitations
       are expected to expire in December 2011. In addition, the
       Company has numerous state and foreign income tax return audits
       currently in process. As of April&amp;#160;1, 2011, the Company
       anticipates that unrecognized tax benefits will decrease by
       approximately $91&amp;#160;million over the next 12&amp;#160;months.

       Current and non-current income taxes payable include accrued
       potential interest of $23&amp;#160;million ($14&amp;#160;million after
       income taxes) at April&amp;#160;1, 2011 and $22&amp;#160;million
       ($13&amp;#160;million after income taxes) at December&amp;#160;31, 2010,
       and potential penalties of $12&amp;#160;million at April&amp;#160;1,
       2011 and $13&amp;#160;million at December&amp;#160;31, 2010.
