[null,"(2)","Estimated Contract Start and Estimated Expiration Dates are calculated as follows: (1) for events estimated to occur between the 1st and 15th of a month, the previous month is reported (i.e. a contract which is estimated to commence on May 4, 2011 will be reported as commencing in April 2011) and (2) for events estimated to occur between the 16th and the end of a month, the actual month is reported (i.e. a contract which is estimated to commence on May 24, 2011 will be reported as commencing in May 2011).  Expiration dates represent the company's current estimate of the earliest date the contract for each rig is likely to expire. Some rigs have two or more contracts in continuation, so the last line shows the estimated earliest availability. Many contracts permit the customer to extend the contract.  "]

Please refer to the “Customer Contract Duration and Dayrates and Risks Associated with Operations” section of the Disclaimers & Definitions for a description of dayrates.  This column may not reflect the rate currently being received under the contract as a result of an applicable standby rate or other rate, which typically is less than the contract dayrate."]
[null,"(4)","The out of service time represents those days where a rig is scheduled to be out of service and not be available to earn an operating dayrate.

[null,"(11)","As a result of the requirement for third party certification of well control equipment on rigs operating in the U.S. Gulf of Mexico, and potential future requirements imposed by our customers, other regulators, and industry standards, Transocean preemptively embarked on a well control equipment certification program in 2010.  We have acquired third party certification of well control equipment on 41 of our 64 active floaters, including 24 of 27 of our ultra deepwater rigs.  All of the rigs currently operating in the Gulf of Mexico have been certified to meet existing regulatory and customer requirements.  Rigs that move between locations or customers may require additional well control equipment certification even if the rigs meet Transocean’s certification program, current customer or regulatory requirements. In 2013, the following floaters are planned to conduct extensive well control equipment overhaul during their out of service period:  Sedco 702, Sedco 711, GSF Grand Banks, GSF Development Driller I, Transocean Searcher, Transocean John Shaw, Sedco 704, Sedco 707, M.G. Hulme, Jr, Sedco 712 and GSF Rig 135."]
