Thanks, Kristyn, and good morning everyone. CBRE is off to a strong start in 2021. Our performance is being propelled by our long standing efforts to diversify our business across four key dimensions; property types, lines of business, geographic markets, and client types. Last quarter, we described in detail how this diversification has enhanced the resiliency of our business. This played out in several ways during the first quarter. Geographically, while activity in some markets notably the Americas remained muted. We saw solid growth in the United Kingdom, parts of continental Europe, Australia, Southeast Asia, and Greater China. Among business lines, mortgage origination and loan servicing, valuations, investment management, and facilities management flogged solid growth, offsetting a continued tepid sales and leasing environment. Industrial and data centers remain preferred property types. Our work in both property types grew robustly in the quarter fueled by booming demand for e-commerce and cloud-based services. Growth in these resilient property types helped to compensate for continued pressure on other property types, particularly office. Our client base is well diversified across the economy. In a quarter we won activity with clients and some industries was down from a year ago. We saw particular strength in our work for life sciences, and industrial and logistics companies, among others. The broad diversification of our business coupled with decisive actions in 2020 to reset our cost structure, underpinned our earnings growth for the quarter, and we expect to see continued benefits in the quarters and years ahead. For full year 2021, we now expect adjusted earnings per share to meaningfully surpass 2019 peak level with potential upside from discretionary capital deployment. Notably, our outlook for 2021 and beyond envision strong growth even with continued pressure on the office market. Clearly, that pressure remains very acute right now particularly in densely populated gateway cities, and will remain challenging for some time to come. However, we strongly believe the pressures on Office will recede from today's extreme levels, as vaccine rollouts continue, and companies settle into new normal work regimes. We expect our growth to be enhanced by capital deployment that is focused on sectors and business lines that are positioned to benefit significantly from secular growth trends. You saw evidence of this with our investment in industrious in the first quarter, which positions us to participate in the rising demand for flexible space solutions. And you can expect to see more evidence of it in future partnerships, sponsorships, and M&A activity. Now, Leah will tell you more about the quarter, our outlook and our capital deployment strategy.
