Thanks, Nick, and good morning, everyone. Welcome to the call, and thank you for your interest in Valaris. During today's call, I will briefly discuss the macro and industry environment that has developed over the last 2 months. I will then provide an update on how these events are impacting the demand for offshore drilling services and Valaris's operations. Finally, I will speak to the cost reduction initiatives that we have underway. Following my comments, I will hand the call over to Jon for his remarks on the first quarter financial results. The coronavirus pandemic has affected businesses and people around the world, creating a global economic crisis, of which we are all acutely aware. In response, world leaders and policymakers have deployed fiscal stimulus programs aimed at limiting the impact of this downturn. While it is uncertain how effective these programs will prove in jump-starting the global economy, it is clear that travel restrictions, quarantine orders and the altered consumer behaviors have had a dramatic impact on the demand for hydrocarbons. We expect commercial and consumer restrictions to be lifted soon in countries around the world. Still, we anticipate that it will take time for consumer behaviors to return to normal. Therefore, there is a highly uncertain picture of hydrocarbon demand, particularly in the near term. Unfortunately, in the face of these demand challenges, the energy industry has been simultaneously facing supply surpluses with competition for market share among producers over the last several weeks. This competitive intensity appears poised to subside following agreements by several oil-producing nations to reduce production, although it remains to be seen if this planned supply contraction will be sufficient. Collectively, these supply and demand pressures have created an excess of hydrocarbons to the point that there are storage capacity concerns, and operators are choosing to shut-in production. In turn, front month Brent crude prices declined from nearly $60 per barrel in late February to less than $20 per barrel earlier this month. In light of this challenging backdrop, customer demand for offshore drilling services has fallen swiftly over the last 2 months. We were receiving about 20 new inquiries per month in late 2019 and early 2020. We expect the majority of these requests to lead to work for rigs in the global fleet. Over the past month, we received a total of 9 such inquiries, and we anticipate that fewer than half of these inquiries will lead to work for Valaris or its competitors. Not surprisingly, with several rigs in the global fleet having come off contract over the past several weeks without follow-on jobs and a shortage of new opportunities, we've already seen global rig utilization drop. This challenging environment is also impacting existing contracts for offshore drillers as operators move to cancel and delay well programs, along with asking for pricing concessions and other modifications to contract terms. Most of our customers have asked for some kind of change to current contract arrangements. We have had 4 contracts terminated and agreed to modify several others. One of the contract terminations we received was for the VALARIS DS-8, which had been operating offshore West Africa, when the rig's blowout preventer became disconnected following a nondrilling incident. At the time, this contract had approximately $150 million of revenue backlog remaining. As previously disclosed, we have an insurance policy that we expect will largely offset the loss of backlog associated with this contract. In addition, we recovered the BOP from the seabed over the past weekend, and we'll now mobilize the rig to the Canary Islands for repairs. However, with the exception of DS-8, challenging market conditions and logistical challenges with our customers, drilling and completion programs, have led to these contract modifications, and we expect that this trend will continue. Travel restrictions and quarantine requirements have also created significant challenges to deploy our global workforce to our offshore rigs and supply these rigs with necessary materials, often in remote locations. That said, I'm pleased to report that despite these challenges, we've been able to keep our rigs crewed and operating. This performance is a testament to our employees to the fantastic efforts of our operations, supply chain and human resources teams as well as our travel partners. I'm especially proud of our offshore crews, many of whom have had to work over for extended periods. They've done so dutifully despite being away from their families during such an uncertain time. In response to this challenging backdrop for the offshore drilling sector, we're taking action to rationalize our fleet, rightsize our support costs and structurally lower our operating expenses. As I've mentioned before, I want Valaris to be the industry cost leader. I believe that the offshore driller that offers safe and reliable operations at the lowest cost is best positioned for success. To minimize our costs, we intend to preservation stack several of our competitive rigs, including 3 drillships, a semisubmersible and 5 jackups. By putting these rigs into a lower state of readiness, we expect to realize more than $50 million of annualized cost savings beginning in the latter half of this year. In addition, we will retire 3 sixth-generation modern drillships, the DS-3, the DS-5 and the DS-6, and 4 benign water semisubmersibles the 5004, the 8500, the 8501 and the 8502. We believe that given the age and capability profile of the global floater fleet, only the most capable modern rigs will be competitive going forward. Given the combination of these rigs' technical capabilities and the amount of time they've been out of service, we do not believe that the necessary economics to reactivate these rigs and make them competitive will ever occur. So we plan to retire these assets. We will also retire 4 jackups. Collectively, the decision to scrap these 11 rigs will save the company more than $30 million in stacking costs annually once sold. Jon will discuss the impairments we've taken on these assets in a moment. We're also rightsizing our shore-based support to better reflect expected fleet utilization levels, which aligns well with the final phase of the merger synergy process that I mentioned on our last conference call. At the end of the first quarter, we achieved a run rate of more than $175 million of combinational synergies, exceeding our $165 million premerger target, 9 months early. Today, our run rate for shore-based support is approximately 65% of the 2 legacy organizations shore-based support costs immediately before the merger closed, inclusive of G&A expense as well as operational and local support that is within contract drilling expense. We expect to further reduce shore-based support costs in the future, lowering them to less than half of what they were in early 2019. While savings through fleet management and shore-based reductions are significant, the most meaningful opportunity to sustainably improve our cash generation potential is by lowering rig operating costs. To address this, we have several initiatives underway, including optimizing manning levels and improving operational and supply chain processes to safely lower repair and maintenance spend. We anticipate that these efforts will help us structurally reduce our daily operating costs. While the savings from these initiatives will depend on rig utilization, we expect to benefit regardless of activity levels. Lastly, we are reducing our capital expenditures for full year 2020 to $120 million, a 25% decrease from our prior estimates, and we continue to scrutinize this spend carefully. With market conditions expected to remain challenging, we're focused on what we can control, providing safe and reliable operations to customers and actively managing our cost base. By delivering efficient services and high levels of uptime, we best position the company to win the limited opportunities for new work that arise and keep our rigs utilized, provided they are economically viable contracts for Valaris. And through the rightsizing of our marketed fleet and overall rig footprint, along with our operating and support costs, we preserve cash as we navigate the industry challenges. And with that, I'll turn it over to Jon.
