Ensco International plc is a global offshore contract drilling company. As of February 15, 2010, our offshore rig fleet included 42 jackup rigs, four ultra-deepwater semisubmersible rigs and one barge rig. Additionally, we have four ultra-deepwater semisubmersible rigs under construction.
We are one of the leading providers of offshore contract drilling services to the international oil and gas industry. Our operations are concentrated in the geographic regions of Asia Pacific (which includes Asia, the Middle East and Australia), Europe and Africa, and North and South America.
We provide drilling services on a "day rate" contract basis. Under day rate contracts, we provide a drilling rig and rig crews and receive a fixed amount per day for drilling a well. Our customers bear substantially all of the ancillary costs of constructing the well and supporting drilling operations, as well as the economic risk relative to the success of the well. In addition, our customers may pay all or a portion of the cost of moving our equipment and personnel to and from the well site. We do not provide "turnkey" or other risk-based drilling services.
We have assembled one of the largest and most capable offshore drilling rig fleets in the world. We have grown our fleet through corporate acquisitions, rig acquisitions and new rig construction. A total of 30 jackup rigs in our current fleet were obtained through the acquisitions of Penrod Holding Corporation during 1993, Dual Drilling Company during 1996 and Chiles Offshore Inc. during 2002. During 2000, we completed construction of ENSCO 101, a harsh environment jackup rig, and ENSCO 7500, a dynamically positioned ultra-deepwater semisubmersible rig capable of drilling in water depths of up to 8,000 feet.
During 2004 and 2005, we acquired full ownership of ENSCO 102, a harsh environment jackup rig, and ENSCO 106, an ultra-high specification jackup rig. Both rigs were initially constructed through joint ventures with Keppel FELS Limited ("KFELS"), a major international shipyard. During 2006 and 2007, we completed construction of ENSCO 107 and ENSCO 108, respectively, both of which are ultra-high specification jackup rigs.
We have contracted KFELS to construct seven ultra-deepwater semisubmersible rigs (the "ENSCO 8500 Series®" rigs) based on our proprietary design. The ENSCO 8500 Series® rigs are enhanced versions of ENSCO 7500 capable of drilling in up to 8,500 feet of water. ENSCO 8500 was delivered in September 2008 and commenced operations in the Gulf of Mexico under a four-year contract in June 2009. ENSCO 8501 was delivered in June 2009 and commenced operations in the Gulf of Mexico under a three-and-a-half year contract in October 2009. ENSCO 8502 was delivered in January 2010 and is expected to commence operations in the Gulf of Mexico under a two-year contract during the third quarter of 2010. ENSCO 8503, ENSCO 8504, ENSCO 8505 and ENSCO 8506 are expected to be delivered during the fourth quarter of 2010, the second half of 2011 and the first and second half of 2012, respectively. ENSCO 8503 has secured a two-year contract in the Gulf of Mexico. ENSCO 8504, ENSCO 8505 and ENSCO 8506 are currently without contracts.
Our business strategy has been to focus on ultra-deepwater semisubmersible rig and premium jackup rig operations and de-emphasize other operations and assets considered to be non-core or that do not meet our standards for financial performance. Accordingly, we sold our marine transportation service vessel fleet, two platform rigs and two barge rigs during 2003. We sold one jackup rig and two platform rigs to KFELS during 2004 in connection with the execution of the ENSCO 107 construction agreement. We also disposed of five barge rigs and one platform rig during 2005 and our last remaining platform rig during 2006.
Our predecessor, ENSCO International Incorporated ("Ensco Delaware"), was formed as a Texas corporation during 1975 and reincorporated in Delaware during 1987. On December 23, 2009, we completed the reorganization of the corporate structure of the group of companies controlled by Ensco Delaware, pursuant to which an indirect, wholly-owned subsidiary merged with Ensco Delaware, and Ensco International plc became our publicly-held parent company incorporated under English law (the "redomestication"). In connection with the redomestication, each issued and outstanding share of common stock of Ensco Delaware was converted into the right to receive one American depositary share ("ADS" or "share"), each representing one Class A ordinary share, par value U.S. $0.10 per share, of Ensco International plc. Our ADSs are governed by a deposit agreement with Citibank, N.A. as depositary and trade on the New York Stock Exchange (the "NYSE") under the symbol "ESV," the symbol for Ensco Delaware common stock before the redomestication.
The redomestication was accounted for as an internal reorganization of entities under common control and, therefore, Ensco Delaware's assets and liabilities were accounted for at their historical cost basis and not revalued in the transaction. We remain subject to the U.S. Securities and Exchange Commission (the "SEC") reporting requirements, the mandates of the Sarbanes-Oxley Act and the applicable corporate governance rules of the NYSE, and we will continue to report our consolidated financial results in U.S. dollars and in accordance with U.S. generally accepted accounting principles ("GAAP"). We also must comply with additional reporting requirements of English law.

Management's Discussion and Analysis of Financial Condition and Results of Operations: INTRODUCTION
We are a leading provider of offshore contract drilling services to the oil and gas industry. We own and operate a fleet of 47 drilling rigs, including 42 jackup rigs, four ultra-deepwater semisubmersible rigs and one barge rig. We are concentrated in premium jackup rigs, but are currently in the process of developing a fleet of ultra-deepwater semisubmersible rigs, capable of drilling at depths of 8,500 feet or greater. Our 47 drilling rigs are located throughout the world and concentrated in the major geographic regions of Asia Pacific (which includes Asia, the Middle East and Australia), Europe and Africa, and North and South America.
We provide our drilling services to major international, government-owned and independent oil and gas companies on a "day rate" contract basis. Under day rate contracts, we provide a drilling rig and rig crews and receive a fixed amount per day for drilling a well. Our customers bear substantially all of the ancillary costs of constructing the well and supporting drilling operations, as well as the economic risk relative to the success of the well. Drilling contracts are, for the most part, awarded on a competitive bid basis. We do not provide "turnkey" or other risk-based drilling services.
During 2008, our revenues, operating income and net income reached record levels as a result of strong rig demand, high utilization and increased day rates in all geographic regions. The decline in oil and natural gas prices from their record highs reached during 2008 and the deterioration of the global economy resulted in significantly reduced levels of jackup rig demand during 2009. Accordingly, our jackup rig operating results declined substantially from record-high levels generated during 2008 due to a decline in utilization of our jackup rigs in all geographic regions.
Operating results in our Deepwater segment improved during 2009. ENSCO 7500 operated in Australia at a day rate of approximately $550,000 for the majority of the year. ENSCO 8500 and ENSCO 8501 commenced operations in the Gulf of Mexico in June and October 2009, respectively. Additionally, ENSCO 8502 was delivered in January 2010 and is expected to commence operations in the Gulf of Mexico under a two-year drilling contract during the third quarter of 2010.
We also continued construction of ENSCO 8503, ENSCO 8504, ENSCO 8505 and ENSCO 8506. These rigs are scheduled for delivery during the fourth quarter of 2010, the second half of 2011 and the first and second half of 2012, respectively. We have funded our ultra-deepwater semisubmersible fleet expansion initiative with cash flows generated from continuing operations. We believe our strong balance sheet, including $1,141.4 million of cash and cash equivalents as of December 31, 2009, and over $2,900.0 million of contract backlog will enable us to sustain an adequate level of liquidity during 2010 and beyond.
We employed 3,585 personnel worldwide as of February 1, 2010, of which 2,347 were full-time employees. The majority of our personnel work on rig crews and are compensated on an hourly basis.
