Definitions and Disclaimers

Day Rate Definition. The day rates reflected in this Fleet Status Report are the operating day rates charged to customers, which may include estimated contractual adjustments for changes in operating costs and/or reimbursable cost adjustments for ongoing expenses such as crew, catering, insurance and taxes. The day rates, however, do not include certain types of non-recurring revenues such as lump sum mobilization payments, revenues earned during mobilizations, revenues associated with contract preparation and other non-recurring reimbursable items such as mobilizations and capital enhancements, and the impact of the fair market value adjustments to previously acquired drilling contracts. Routine and non-routine downtime may reduce the actual revenues recognized during the contract term. Additionally, the Company occasionally negotiates special rates with customers as noted in the comments that reduce revenues recognized during the contract term.

Forward Looking Statement. Statements contained in this Fleet Status Report that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements include words or phrases such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “project,” “could,” “may,” “might,” “should,” “will” and similar words and specifically include statements involving future rig day rates; cost adjustments; utilization; estimated rig availability; contract duration, status, terms and other contract commitments; customers; rig enhancement projects; new rig commitments; the expected period of time and number of rigs that will be in a shipyard for repairs, maintenance, enhancement or construction; and scheduled delivery dates for new rigs.
