Thanks, Sean, and good morning, everyone. Before Jay takes us through the financial results, I will discuss the Pride acquisition, second quarter highlights and the state of our markets. We have a great deal to discuss this morning, so our prepared remarks will be a little longer than they normally are for our earnings calls. Starting with the Pride acquisition. We successfully completed the transaction on May 31, and the integration process is going very well. We formed integration teams for 15 separate functional areas early this year, and they have done an excellent job ensuring a smooth transition. Our new organizational structure is in place, and most employees affected by the acquisition are in their new positions. Marketing teams are working closely with customers on outstanding bids and tenders, and we are leveraging our broader geographic reach, enhanced drilling fleet and larger customer base. Operations is actively integrating systems and procedures to ensure consistency across our organizations, especially our safety management systems, and we are capitalizing on our increased scale to take advantage of purchasing efficiencies to lower our cost with vendors. As we integrate our rig fleet and shore-based operations, especially in regions new to us like Brazil and West Africa, we are being very carefully to properly assess the current state of operations before proposing any potential changes. We know that our workforce is our greatest asset, and we expect to promote and add hundreds of new employees over the coming years as our new build rigs come out of the shipyard and go to work around the world, especially in the highest growth markets like Brazil and West Africa that have large numbers of new discoveries. Our Dallas-based employees are to be recognized and commended for their many contributions to our company over the years. Dallas has been our home for our corporate administrative office, and all those it employs are either in the process of relocating their families to Houston or moving on to new opportunities. Now let me cover some of our second quarter highlights. First, we achieved a significant milestone in Ensco's history by reaching more than 100 years of contracted backlog. This equates to more than 1.4 years per rig in the active fleet, including rigs that are cold stacked. ENSCO 8504, which we took delivery of yesterday from KFELS, was contracted with Total in Brunei during the second quarter. ENSCO 5001 are our new contracts for work extending into 2014 in Angola and South Africa. We mobilized ENSCO 105 to Southeast Asia, where the jackup rig will commence operations in Malaysia under a one-year term contract. And we have signed long-term contracts with Saudi Aramco for 5 of our jackups, 3 of which have been stacked for over a year. All of our marketed jackups in the U.S. Gulf of Mexico were contracted during the second quarter, and all of our North Sea and Mexico jackup rigs are contracted into 2012. For our deepwater segment, average day rates are projected to increase in the third and fourth quarter, since 3 of our drillships have recently commenced their original 5-year contract and ENSCO 8502 has commenced its original 2-year contract, all at full-day rates. In fact, all of our deepwater rigs contracted in the U.S. Gulf of Mexico are now earning full-day rates, and we anticipate that ENSCO 8503 will begin its original 2-year contract in the U.S. Gulf of Mexico in the fourth quarter at a day rate of $530,000 plus reimbursables of about $54,000 per day. In terms of operational excellence, ENSCO 8503, which commenced drilling operations last quarter for Telo, has performed extraordinarily well and has benefited from our experience with our first 3 8500 Series rigs. In fact, our ENSCO 8500 Series rig had virtually no downtime during the second quarter and achieved 99% utilization. This is the type of performance that we believe will allow us to maintain our #1 ranking in customer service in the offshore drilling sector. As I reflect on our strategy for the ENSCO 8500 Series rigs initiated back in 2005 and our results since then, I think it's fair to say that we've realized all of the intended benefits and more. We designed the rigs to meet the sweet spot of the market at a price tag that was considerably less than what our competitors paid for their rigs. While customers were early advocates of the concept and design, some market commentators were skeptics and didn't think our rigs would earn jobs, perform well or work in certain markets. In fact, the results show we have had excellent operating performance. Customers have had great success with our rigs, and new customers are interested in contracting our newbuild semis in additional markets around the world. As I mentioned earlier in my remarks, we took delivery of ENSCO 8504 from KFELS yesterday. The rig was on time and within budget. The remaining rigs in the 8500 Series are scheduled to be delivered on time and on budget, and the advantages of standardization across the entire 7 rig series are becoming more evident every day. The returns on capital for the rigs delivered to date have comfortably exceeded our cost to capital and the 15% after-tax threshold we set as a minimum goal in 2005 when we started this investment. Based on our current discussions with customers, we feel encouraged the 2 remaining uncontracted rigs will also exceed our investment thresholds. In summary, we feel really good about the returns and operational performance for these rigs. Now let's discuss the market. I will begin with the deepwater markets, where Ensco now has the second newest fleet in the world. All but one of our active deepwater rigs have commitments to at least the first half of 2013 and with more than a dozen prospects and bids in the market, we believe we are well positioned to match our availability of ultra-deepwater drill ship and semis that are under construction with near and midterm market demand. In Brazil, we will soon have 6 deepwater rigs operating. We expect the market for deepwater rigs in Brazil to remain strong with new discoveries being announced almost weekly. Petrobras remains the driving force behind the deepwater market growth and recently issued tenders for multiple rigs for 3- to 5-year term contracts. In the U.S. Gulf of Mexico, we are encouraged the deepwater permits are being issued and knowing a few deepwater units in this region are now available. Several operators are now discussing requirements for additional rigs commencing in late 2011 and 2012. The West African deepwater market has improved significantly during the quarter with contract awards, prequalifications, tenders and inquiries from multiple operators. Deepwater activity in Asia has seen a significant increase across Malaysia, Brunei and Indonesia, with national and independent operators participating. Floater activity in the Mediterranean and Black Sea is finally balanced. Currently, there are outstanding opportunities in Egypt and Israel and longer term, there is potential in Libya. Moving to midwater markets. Although the worldwide midwater fleet will remain challenged in 2012, Ensco's fleet of 6 rigs has a strong backlog position. All were contracted to year end, and 2 were contracted into 2013. In Brazil, we have 5 semisubmersibles that are currently -- are contracted. And while 2 are rolling off contract later this year, we anticipate that they will continue to work in the region. West Africa is a slow midwater market despite the recent demand that reactivated 3 stacked rigs. Several industry rigs are scheduled to be free next quarter, and competition will be intense for the few opportunities identified. ENSCO 5003, our only midwater rig in the region, is contracted to at least the end of the year, and we believe we have some advantages over other marketed rigs. Turning to the jackup markets. In the U.S. Gulf of Mexico, Ensco has 8 marketed jackups that had very good utilization in the second quarter. With hurricane season upon us, though, jackup utilization has began to decline after steadily rising since the beginning of the year. The market will be competitive for the remainder of the year, but the departure of several 400-foot jackups and increasing demand from PEMEX will be helpful factors. In Mexico, our 4 jackup rigs are contracted to PEMEX with terms into 2012. With PEMEX's intention to increase their jackup fleet by some 20 rigs, tender activity is increasing and we expect it to continue in the coming months. Discussions surrounding rate caps and other contractual terms are ongoing, and we believe PEMEX is reconsidering some of their limits in order to fulfill their drilling requirements. In the North Sea, all of our 8 rigs are contracted. The standard duty market has recovered, and forecasts predict an undersupply of 1 or 2 units for the remainder of the year and into 2012. A number of operators are unable to secure rig time. The heavy-duty jackup market also has been robust, and one of the industry's 3 stacked rigs was recently reactivated. We already are receiving inquiries for work in the Central North Sea for 2012 and 2013 that targets markets for our 2 newbuild jackups. The Mediterranean jackup market will remain a challenge for the foreseeable future. The market for jackups in the Middle East tightened considerably this quarter, and we expect this trend to continue throughout the year end. The primary driver has been Saudi Aramco. Since October 2010, Aramco has contracted 16 rigs and may issue 6 more tenders in the second quarter. These tenders call for all types of rigs: HPHT, high-spec gas drilling and workover. We also have seen an increase in the demand in the rest of the Middle East, fueled by relatively high commodity prices. We are participating in tenders in Abu Dhabi, Qatar, Bahrain, and there is an outstanding tender for 2 high-spec jackups for the longer-term programs in the neutral zone. In the Southeast Asian market, Ensco has all of its rigs contracted. A number of operators are locking in long-term contracts, while other operators are straining to get the programs. We are in discussions with operators for our limited number of jackups that will be coming available. To summarize, growing exploration and appraisal success, emerging deepwater basins, rising energy demand, healthy commodity prices and increased client spending all bode well for long-term growth. We believe demand for deepwater floaters will continue to grow as clients are under pressure to efficiently replace production in the midst of increasing technical complexity and rising safety standards. We expect 50% or more of the worldwide deepwater fleet will continue to be occupied by development and completion work, creating long-term opportunities. Activity is improving in the U.S. Gulf of Mexico. Petrobras continue to contract rigs due to their increasing geological successes in pre-salt. Deepwater opportunities are opening up in new areas around the world, and clients are placing a greater value on high-specification equipment. The jackup markets are picking up pace as well, with increasing utilization in most major markets. Saudi Aramco and PEMEX are adding multiple jackups to their fleet, and the North Sea is almost fully utilized. To date, newbuild jackups are being absorbed into the fleet. Most clients are focused on hiring companies with proven operational excellence, competent crews and successful safety and environmental track record. In essence, we're seeing a flight to quality by customers who favor established high performing companies such as Ensco. Scale is an important factor, and having newer assets also gives a distinct advantage. Our newbuild delivery schedule over the next 12 to 24 months not only puts us ahead of the curve in terms of meeting new customer demand, it also will perpetuate our advantage of having one of the youngest fleets in the industry. And our new drillship and jackup newbuild options that are available to the end of August give us additional flexibility to grow our company. In closing, when we announced our plan to acquire Pride, we made the following commitments to our shareholders: We will stay laser focused on operational execution, we would quickly integrate the 2 companies, we would work diligently to realize cost synergies from the transaction, we believe there would be revenue synergies from the transaction and the transaction would be accretive to our financial results. While our team has been working countless hours to get us where we are today, there remains plenty of work to do. I'm pleased to report we are on track for keeping these commitments. Now I'll turn it over to Jay.
