This evaluation is based on a number of factors, including the length of time and extent to which the fair value has been below our cost basis and adverse conditions related specifically to the security, including any changes to the credit rating of the security by a rating agency. As of March 31, 2011 and December 31, 2010, we believe the cost bases for our available-for-sale investments were recoverable in all material respects. </div> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringThis item represents the entire disclosure related to Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities.
