Thanks Bob. I want to begin by welcoming Lea. She'll be a great addition to our executive team, and I look forward to working with her. Now please turn to slide 5. This is the first quarter where we are reporting results under our new business segments. And as a result, we are providing further incremental transparency into our performance. To help you with this transition, we have restated historical quarterly data under our new segments back to the first quarter of 2017. We have also provided supplemental reports under our prior geographic reporting methodology. Both are posted in Excel files on the Investor Relations section of our website. Turning to the quarter. As Bob noted, CBRE had a great start to 2019 with growth of 46% in adjusted EPS and 29% in adjusted EBITDA, almost all of which was organic. We appeared to be on track for a tenth consecutive year of double-digit adjusted EPS growth. Our Advisory Services and Global Workplace Solutions segments combined experienced 14% revenue growth and 11% fee revenue growth, both in local currency. 22% adjusted EBITDA growth in US dollars and 190 basis point expansion of adjusted EBITDA margin on fee revenue. The increase in margins was driven by double-digit fee revenue growth, a favorable business mix and cost discipline. The net impact of a handful of choppier items such as mortgage servicing gains and fluctuations in currency drove approximately 1/4 of this margin expansion in the quarter. We also had strong performance in our real estate investment segment with adjusted EBITDA increasing $37 million over the prior year within this segment investment management benefited from co investment gains, and development benefited from several larger dispositions. GAAP earnings in the quarter were negatively affected by the non-cash write-down of intangibles in our real estate securities investment management business. As we have discussed previously, this business has been impacted by the industry-wide shift in investor preferences to passive investment programs. The securities business now comprises less than 10% of AUM in our investment management business. Finally, Moody's recognized the strength of our balance sheet with an upgrade last week to BAA one in line with our BBB plus rating from S&P. Now please turn to Slide 6 for a discussion of our Advisory Services segment. This segment includes our core services listed on the right-hand side of the slide. For the quarter, this segment realized adjusted EBITDA growth of 22% in US dollars despite the drag from lower property sales on fee revenue growth of 10%. Performance was led by our leasing business which had another great quarter increasing globally by 22% and growth was almost entirely organic. In the US, Leasing was up 28% with strong demand from multiple sectors including consumer products, energy and technology. We benefited from several large deals, out size growth from account based clients and ongoing recruiting gains. With growth in leasing revenues for the trailing 12-months averaging over 20%, comparisons going forward will be more challenging. Loan servicing revenue grew 10% and our portfolio increased to a record $210 billion. Capital markets revenue which includes both property sales and commercial mortgage origination declined by 1% globally, reflecting meaningful gains in market share. Within capital markets, commercial mortgage origination revenue rose 13%fueled by robust activity with the US government sponsored enterprises, as well as banks. Property sales revenue declined 5% against a challenging 11% growth comparison in the prior year. The comparisons become easier going forward. The declining property sales reflect a tepid macro environment where market wide sales volume decreased in all three global regions. Despite the softer quarter, we continue to take share in our property sales business. A modest 1% decline in US sales revenue reflects significant market share gains as estimated market volumes decreased 8% according to real capital analytics. Overall, America's property sales declined 4% driven by Canada which faced a 31% prior year growth comparison. International growth and sales was negatively impacted by weakness in our residential sales businesses in Australia and Singapore, which offset otherwise strong performance particularly in Greater China and Japan. Adjusted EBITDA on fee revenue margin expansion of 200 basis points for the advisory services segment was driven by overall solid revenue growth, a favorable business mix and heightened focus on cost discipline. Now please turn to Slide 7 for a discussion of our Global Workplace Solutions segment, sometimes referred to as our outsourcing business. This segment achieved fee revenue growth of 12% in local currency and 8% in US dollars. All three regions posted double-digit growth in local currency on top of strong double-digit growth in Q of the prior year. FX was particularly challenging headwind in the quarter but should moderate as the year progresses. Global Workplace Solutions adjusted EBITDA grew by 20% in US dollars, reflecting strong operating leverage. We started the year by winning several large new contracts making it our strongest ever first quarter for new business wins. By example, we significantly expanded our relationship with Lowe's Home Improvement by combining our traditional facilities management strengths with the facility source technology and services capabilities that we acquired last year. Facility source had a small pilot program with Lowe's in place at the time of the acquisition. With this new contract, we now manage 196 million square feet for Lowe's nationally. We expect facility source will continue to drive growth with clients that have large, widely dispersed operations. With a record pipeline of pursuits, global workplace solutions are off to an excellent start to 2019. Now please turn to Slide 8 for a discussion of our Real Estate Investment segment. This segment includes our investment management business which includes contractual asset management fees, our development business and Hana, our flexible space solutions business. First quarter EBITDA growth of $37 million in this segment exceeded our own expectations. Investment management capital raising set a new record at $13 billion over the past 12-months. Assets under management increased by $1.7 billion in the quarter to reach a new high at more than $107 billion. Investment management contributed $6 million to adjusted EBITDA growth, co-investment returns totaled $13 million driven by the strong rebound in public equity prices in Q1 more than offsetting the decline in carried interest revenue versus last year. The development business continues to exhibit excellent momentum, contributing $36 million to adjusted EBITDA growth driven by several large asset sales, including an office disposition that had been budgeted for later in the year. In-process activity also reached a record level totaling $9.7 billion at the end of Q1. As you know, EBITDA from our development business can be choppy from quarter-to-quarter. Last year, the second and third quarters generated the majority of our EBITDA. This year, we expect the bulk of our EBITDA from development to be generated in the first and fourth quarters. Finally Hana incurred startup costs in line with our expectations. In its early stages Hana is being very well received, filling a marketplace need for property owners looking to participate in the powerful, flexible space trend.
