Thank you, Christian. Before I begin a reminder that variances are against the prior year period and local currency unless otherwise noted. The first quarter was generally consistent with the fourth quarter trends we discussed our February call. While the macroenvironment has presented challenges to growth in certain areas of our business over the past couple of quarters, we see strong underlying momentum building across our entire business. Our growth oriented investments in our people and platform over the past several years provide a strong foundation for the eventual rebound in our transactional business lines. As well as continued growth of our more cyclically resilient business lines. We remain focused on delivering a high level of client service and capturing the significant market opportunities to drive both near term and long term growth, profitability and cash flow. At the consolidated level, first quarter fee revenue was $1.6 billion, a 15% decline from a particularly strong first quarter of 2022. Looking at the two periods on a stacked year-over-year growth basis in USD, they totaled a 17% increase. First quarter adjusted EBITDA was $109 million, down 61% and the adjusted EBITDA margin contracted 780 basis points to 6.6%. The declines are mostly attributable to the drop in fee revenue and our leasing and investment sales, debt and equity advisory business lines as well as a $21 million adverse change in equity earnings. The lower equity earnings contributed approximately 130 basis points to the margin decline. Higher fixed compensation expense tied to growth related investments and headcount during the first nine months of 2022 was also a headwind to profitability, partially offset by the ongoing cost reduction actions we discussed last quarter. Adjusted EPS of $0.65 declined 84% driven in part by higher interest on top of the lower adjusted EBITDA, partially offset by a 5% reduction in the average share count. Putting the first quarter results in perspective, our investment sales, debt and equity advisory fee revenues were the lowest since the second quarter of 2020. The most heavily impacted pandemic period. Additionally, over the past six quarters, we have been investing in our capital markets and other businesses, which has an amplified headwind effect on the quarters profitability when combined with the decline in fee revenue. We expect the investments to help accelerate growth as a recovery unfolds. We continue to actively manage our business to drive further long term improvements in efficiency. Of the $125 million of cost savings we discussed last quarter, we achieved approximately $15 million of cost savings in the first quarter, and anticipate the remaining $110 million to be fairly evenly split over the last three quarters of the year. In other words, the full run rate effect of the $140 million in annualized cost savings we previously announced, is expected to commence in the second quarter. The cost actions are largely focused on non-revenue generating roles that we identified as part of our global realignment of our business lines last year. We continue to opportunistically invest in areas that we believe have attractive growth and return prospects. Moving to a detailed review of our operating performance by segment, beginning with Markets Advisory. First quarter leasing fee revenue declined 18% following a 46% growth rate in the prior year quarter for a two year stacked USD growth rate of 26%. As macro conditions varied across regions, so to that our leasing fee revenue, with the Americas down 21% and EMEA falling 12% while Asia Pacific grew 23%. The strength in Asia Pacific was largely driven by the recovery in Greater China. Globally, all primary asset classes saw transaction volume decline, along with lower average deal size, but this was most pronounced in the office sector. Our first quarter office sector fee revenue fell 17% slightly better than the 18% contraction in global office fee volume according to JLL research. In the industrial sector, the revenue declined 14% which compares favorably with a 37% decrease in global industrial market activity, according to JLL research. The contraction in industrial sector leasing activity is directionally consistent with expectations given a tight supply and significant growth seen over the past several years. As Christian described, we're seeing more sustained leasing demand for high quality assets despite softer demand more broadly. Our global growth leasing pipeline continues to show resilience, getting cause for cautious optimism for the full year 2023. However, near term activity is likely to be subdued considering the economic backdrop. Also within markets advisory, property management fee revenue for the first quarter grew 12% attributable in part to portfolio expansions in the Americas, an incremental fee from interest rate sensitive contracts in the UK. The decline in the advisory consulting and other fee revenue was primarily due to the absence of revenues associated with the exit of a business that we previously announced in the fourth quarter of last year. The markets advisory first quarter adjusted EBITDA margin declined 380 basis points from a year ago to 11.2%, primarily due to lower leasing fee revenue. Shifting to our Capital Markets segments, the market conditions Christian described were a key factor in the 39% decline in segment fee revenue. The contraction is of a very strong first quarter 2022 growth rate of 54% resulting in a two year stacked USD growth rate of 10%. Our global investment sales fee revenue, which accounted for approximately 35% of segment fee revenue, fell 56%, the decline was broad based across nearly all geographies and asset classes, and compares with a 54% decline in the global sales volume Christian referenced. For perspective, the first quarter market volume decline was the sharpest since the first quarter of 2009. And in terms of dollars, with the lowest overall market volume since the first quarter of 2012. Growth in EMEA valuation advisory fee revenue mostly offset declines in Asia Pacific and the Americas, leading to a 3% reduction in the total valuation advisory fee revenue. Our loan servicing fee revenue fell 6% on approximately $5 million of lower prepayment fees, which masked about 5% growth of recurring servicing fees. The decline in prepayment is coincides with the rise in interest rates, which dampens the financing activity. The underlying growth of the servicing fees was driven by the growth in our Fannie Mae portfolio. The Capital Markets adjusted EBITDA margin contraction was predominantly driven by lower fee revenue, and the impact of the growth oriented headcount additions we made an early to mid-2022. With our investments and our capital markets talent and platform over the past several years, we are well prepared for a strong recovery when transaction volumes return. Looking ahead, the global capital markets investment sales, debt and equity advisory pipeline is building at a slower rate than historical trends in a typical year, and is down mid-teens compared with this time last year. While we do see early signs of improving pipeline activity, particularly within the US, the amount and pace of revenue growth throughout the year will be heavily influenced by the factors impacting field timing and closing rates that Christian described. Moving next to Work Dynamics. Fee revenue growth of 11% was consistent with the prior quarter. The growth was led by 24% increase in project management mostly attributable to continued project demand, particularly in the US, France and the Middle East. Workplace management exhibited continued resilience, growing 3% on the back of a strong growth year earlier. The slowdown in leasing activity, particularly in the Americas, adversely impacted portfolio services fee revenue growth in the quarter. The Work Dynamics adjusted EBITDA margin contracted 350 basis points from a year ago, driven by $9 million of losses on Tetris contracts in Europe, as well as incremental investment in sustainability and technology, partially offset by the higher fee revenue. Overall, we are pleased with the underlying performance of work dynamics business and are confident in the segment's growth trajectory. The first quarter was one of the strongest on record for new sales, as measured by contract wins and expansion, and had a 98% contract renewal rate, supporting growing momentum for the rest of the year and into 2024. The near term project management pipeline remained solid, and we are focused on securing mandates for the latter part of the year. As Christian mentioned, within workplace management, we secured several new contracts from Fortune 100 companies, which will begin in the latter part of the year. And our pipeline continues to build as the demand for professional management of corporate real estate increases. Turning to JLL Technologies. Fee revenue grew 29% and acceleration from fourth quarter 2022 organic growth of 21%. An existing large enterprise clients continue to increase their utilization of our platform, particularly our solutions and services offerings. As a reminder, the majority of JLL Technologies revenue is recurring in nature, and we continue to see strong retention. The path to segment profitability remains a priority. Indicative of our focus JLL Technologies fee based operating expenses excluding carried interest grew just 7%. The combination of the fee revenue growth and operating efficiency gain drove an improvement in JLL Technologies adjusted EBITDA margin, tampered by an $8 million adverse [inaudible] in equity earnings net of carried interest. Equity earnings in the quarter were driven by a handful of valuation increases, largely reflecting subsequent financing rounds at increased valuations. Now to LaSalle. Assets under management rose 8% from strong capital deployment and valuation increases over the prior 12 months, which translated to a 9% rise in advisory fee revenue, mostly within our core open end fund. Given the evolving market environment, new capital deployment is subdued and impacting transaction revenues compared to the prior year. The pace of capital deployment may also impact how quickly growth for new mandates will offset the loss of the UK separate account mentioned last year. Moderating asset valuations broadly drove the $7 million decline in equity earnings from the prior year. The lower equity earnings were at 640 basis point headwind to sales adjusted EBITDA margin, which contracted 570 basis points. The increase in advisory fee revenue and platform scale benefits were offset by lower transaction fee revenue. Cost mitigation actions over the past few quarters lifted profitability. Shifting to free cash flow. Net outflow in the quarter was $766 million consistent with a year earlier, as a $130 million improvement in net working capital was offset by $130 million and lower cash from earnings. The lower cash from earnings was in part due to the decline in capital markets and markets advisory business performance. Better working capital was driven by lower annual incentive compensation and commission payments in 2023 compared to 2022, and incremental cash inflow from trade receivables, partly offset by an additional pay period in the current quarter, and incremental cash outflow and net reimbursable tied to growth of the workplace management business line within work dynamics. Cash Flow conversion is a high priority, and we remain focused on improving our working capital efficiency. Now for an update on our balance sheet and capital allocation. As of March 31, reported net leverage was 1.9x below the high end of our target range and up from 0.8x a year earlier, primarily due to net investment activity and share repurchases, together with lower free cash flow over the trailing 12 months. As a reminder, our leverage ratio typically peaked in the first part of the year, and we have a history of deleveraging as the year progresses. Our liquidity totaled $1.7 billion at the end of the first quarter, including $1.3 billion of undrawn credit facility capacity. Though we did not repurchase any shares in the first quarter, our period and share count was down about 4% from a year earlier as a result of our approximate $450 million of share repurchases over the past 12 months. We have reinstated our share repurchase program beginning in the second quarter, and expect to repurchase a modest amount of shares in the quarter. The amount of share repurchases over the full year will be dependent on the evolution of the market recovery and the performance of our business, particularly cash generation. Approximately $1.2 billion remained on our share repurchase authorization as of March 31, 2023. Over the past two to three months, we've seen general stability in a number of key market indicators and business trends, even considering the recent bank stresses. So the prevailing economic conditions lead us to expect the softness and are more transaction oriented the revenues will persist into the second half of the year. All considered, we remain focused on achieving our full year 2023 target adjusted EBITDA margin range of 14% to 16%. We are navigating a shifting macroenvironment that creates short term headwinds for certain areas of our business. The industry tailwinds, we previously highlighted remain intact. And we do not expect the current macro pressures to undermine growth trends over the medium and long term. Accordingly, we continue to proactively position our people and our platform to both emerge stronger through the market recovery and enhance the growth of our cyclically resilient business line. Christian, back to you.
