Thanks, Suzanne. Good morning, everyone, and thank you for joining us. Before we get into the results of the fourth quarter, I want to discuss the other release we made today. Last Friday, our Board of Directors unanimously approved a plan to change our corporate structure, which we believe will enhance shareholder value by further strengthening our long-term competitive position as a global contract driller. Under the proposed plan, our legal domicile will change from Delaware to the U.K. where we already have substantial and growing operations. This move is designed to ensure that Rowan will remain competitive in our industry over the long-term and have maximum flexibility in terms of the markets in which we work. The offshore drilling industry is a global business, and over the past several years, Rowan has been steadily moving away from being a predominantly U.S.-based contractor and toward geographic diversification.By way of example, in 2004, 10% of our revenues were generated outside the U.S. In 2012, we estimate that 81% of our revenues will be generated outside the U.S. In addition, 96% of our contract backlog is from markets outside the U.S. Eight of our top 10 customers are headquartered outside the U.S., and as you're aware, the overwhelming majority of our competitors are domiciled overseas.
