Note 2: OneSubsea™
  
On November 15, 2012, Cameron and Schlumberger announced their intent to create OneSubsea, a joint venture to manufacture and develop products, systems and services for the subsea oil and gas market.  Cameron will contribute its existing subsea business and receive $600 million from Schlumberger while Schlumberger will contribute its Framo, Surveillance, Flow Assurance and Power and Controls businesses.  As 60% owner, Cameron will manage the joint venture, consolidate it in its DPS segment and reflect a minority interest in its financial statements for Schlumberger's 40% interest in the joint venture.  The transaction is subject to regulatory approvals and other customary closing conditions, which are expected to be completed during the second quarter of 2013.
