Thank you, Henry, and greetings, everyone. I'll echo Henry's enthusiasm for the strong momentum with which we've started the year. Total subscription sales across MSCI reached a first quarter record high. Asset-based fees also achieved a milestone, surpassing $500 million in run rate. As I highlighted during our Investor Day presentation, our very deep client relations are central to our successful commercial model. In our 2020 client survey, MSCI's global Net Promoter Score, a leading indicator of client retention and loyalty, increased to 45 points, up 6 points compared to 2019 and above the average scores for the financial services, enterprise software and SaaS industries. In the first quarter of 2021, net new recurring subscription sales were nearly $34 million, growing 46% year-on-year driven by ESG and climate as well as double-digit growth across analytics, index and private assets. Accordingly, MSCI's subscription run rate expanded 11% or nearly $140 million versus the prior year. This included a remarkable 42% increase, or nearly $44 million, in ESG and climate's run rate as well as a more than $60 million increase in index's subscription run rate. MSCI's total retention rate in the first quarter was 96.3%, up 130 basis points year-over-year. Henry noted our efforts with wealth managers. As you are aware, this is one of our newer but very promising client segments. At the end of the first quarter, we had a $64 million run rate from wealth managers, up 28% year-over-year. We also continue to see strong growth and continued momentum in our more established client segments. For example, subscription run rate from asset managers and asset owners, which together comprise about 2/3 of total subscription run rate, were up 11% year-over-year. Let me make a few observations about this quarter from a regional point of view. In EMEA, MSCI generated 16% subscription run rate growth, driven by strong growth across product segments, but with particular success in ESG and climate, as the forthcoming COP26 Conference, the need for TCFD reporting and the significant increases in net zero alignment spurred strong client activity. In APAC, new subscription sales are regaining momentum and grew 36% year-over-year in the first quarter. Business activity is returning to normal subsequent to the pandemic. In Japan, opportunities were created by new regulations on liquidity. Total subscription run rate growth was strong across the regions, growing 16%, 9% and 8% year-over-year in EMEA, APAC and the Americas, respectively. On the back of a great start to the year, our global sales pipeline remains healthy across both products and regions as well as above levels of last year. As Henry noted, the rapidly growing attention to climate risk has been a significant contributor to our sales pipeline as MSCI's expertise is well recognized. To that end, we continue to enrich our suite of climate data, models and technology. Let me provide a few examples. Following our successful introduction of MSCI climate scenario analysis models, including climate value at risk, we are developing climate models for new asset classes, including fixed income. We also continue to enrich our data sets, including for Scope 3 emissions and to strengthen our TCFD reporting solutions. We have completed TCFD reporting projects for some of the world's most prominent asset owners and institutions, ranging from climate risk portfolio-level reporting to temperature alignment comparisons to benchmarks. We recently launched MSCI Climate Paris Aligned fixed income indexes, following our successful launches of MSCI fixed income climate indexes and MSCI Climate Paris Aligned equity indexes. Finally, and coming soon, we plan to introduce cloud native climate risk-focused application that showcases MSCI climate models and data. This offering leverages Microsoft tools and AI technology in connection with our broader efforts to deliver investment solutions as a service. As Henry referenced, we are investing to capitalize on the sizable addressable opportunities in climate, including in areas like banks, stress testing and corporate needs to capture climate stress tests. Both have the potential to become mandatory requirements in the future. Overall, MSCI's run rate from climate now totals over $20 million across the franchise. We expect this part of the business to continue to grow rapidly as we help investors evaluate, manage and address climate risk in their portfolios. Before I move on from solutions, I'll provide a brief update on our progress in fixed income. In analytics, our fixed income portfolio management run rate has expanded nearly 60% off a small but very rapidly growing base. We are gaining traction by bringing to market fresh solutions that improve upon the quality of models, workflows and usability of legacy solutions. We're also benefiting from the investments we've made over the years to improve our single security analytics, factor models and performance models. In ESG and climate, we're developing physical risk climate scores for U.S. municipal bonds. We're also building new applications for our Climate Value-at-Risk tool, including for sovereign bonds. In index, we have seen our clients continue to attract assets in fixed income ETFs linked to MSCI and Bloomberg Barclays MSCI indexes. AUM in those ETFs reached more than $20 billion at the end of the first quarter of 2021, growing more than 200% year-over-year. As you can see, our strategy in fixed income is to differentiate ourselves by providing high-quality products that play toward specific areas of strength. Our ability to integrate offerings across the MSCI franchise also continues to be an important differentiating factor and driver for clients to turn to MSCI for fixed income solutions. Across asset classes, products and data, we continue to prioritize an open architecture approach to enhance the client experience and flexibility across MSCI. Recently, we integrated MSCI's ESG research into our hedge platform, such that we can now provide ESG and climate metrics calculated on position-level holdings, allowing hedge funds to support asset owner net zero goals. We're also further enhancing climate data integration capabilities in our risk management platform within analytics. Given the strong momentum with which we've begun this year, we have accelerated the pace of our investments in key growth areas such as ESG and climate, fixed income and private markets to enhance our data, research, technology and client coverage. As always, we will make these investments in the context of our rigorous Triple-Crown framework. Let me now turn the call over to Andy. He will speak more to our outlook as part of his review of our guidance as well as further discuss our recent financial performance. Over to you, Andy.
