The investments with unrealized losses consist of corporate debt securities and an auction rate security. In making the determination that the decline in fair value of these securities was temporary, the Company considered various factors, including but not limited to: the length of time each security was in an unrealized loss position; the extent to which fair value was less than cost; financial condition and near term prospects of the issuers; and the Company’s intent not to sell these securities and the assessment that it is more likely than not that the Company would not be required to sell these securities before the recovery of their amortized cost basis. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">     The Company’s strategic equity investments include common stock in public companies with which the Company has or had a collaborative arrangement. In addition, in December 2009, the Company entered into a collaborative arrangement with, and made an investment in, Acceleron Pharma, Inc. (“Acceleron”). The Company’s Chairman, President and Chief Executive Officer is one of nine members of Acceleron’s board of directors. The Company’s December 2009 investment in Acceleron consisted of an $8.0 million purchase of shares of Series D-1 convertible, redeemable preferred stock. In July 2010, the Company invested an additional $0.5 million in exchange for shares of Series E convertible, redeemable preferred stock and common stock warrants. The Company accounts for its investment in Acceleron under the cost method as Acceleron is a privately-held company over which the Company does not exercise significant influence. The Company will continue to monitor this investment to evaluate whether any decline in its value has occurred that would be other-than-temporary, based on the implied value from any recent rounds of financing completed by Acceleron, specific events at Acceleron, market prices of comparable public companies and general market conditions. The Company’s investment balance of $8.5 million and $8.0 million at September 30, 2010 and March 31, 2010, respectively, is recorded within “Other assets” in the accompanying condensed consolidated balance sheets. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif"> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock This item represents the entire disclosure related to Marketable Securities which may consist of all investments in certain debt and equity securities (and other assets).
