JANA is a private money management firm which holds Shares of the Issuer in various accounts under its management and control. JANA Partners Management GP, LLC (the “GP”) is the general partner of JANA.  The senior managing member of the GP and indirect control person of JANA is Barry Rosenstein (the “Principal”).

Item 3.	SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.
Item 3 of the Schedule 13D is hereby amended and restated in its entirety as follows:

 

The 6,553,120 Shares reported herein by JANA were acquired at an aggregate purchase price of approximately $226 million. Such Shares were acquired with investment funds in accounts managed by JANA and margin borrowings described in the following sentence. Such Shares are held by the investment funds managed by JANA in commingled margin accounts, which may extend margin credit to JANA from time to time, subject to applicable federal margin regulations, stock exchange rules and credit policies. In such instances, the positions held in the margin accounts are pledged as collateral security for the repayment of debit balances in the account. The margin accounts bear interest at a rate based upon the broker’s call rate from time to time in effect. Because other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Shares reported herein.
