Thank you, Christian. Before I begin, a reminder that variances are against the prior year period in local currency, unless otherwise noted. I'm pleased with the focus of our leadership teams over the course of last year to strengthen our platform, improve our operating efficiency and drive long-term value creation while continuing to deliver exceptional service to our clients. Strong progress was made despite persistent softness in transactional market activities evidenced by full year investment sales market volume reaching its lowest level since 2012 as well as office and industrial leasing volumes 16% lower than 2020. So our transaction-oriented fee revenue fell 17% for the full year. Both leasing and investment sales outperformed respective declines in the broader market. Our resilient fee revenues grew 5% for the full year with growth accelerating in the fourth quarter as we transition new client mandates that we won earlier in the year, a testament to the trust our clients have in JLL managing their real estate portfolios. Over the course of the year, we took actions that lowered our cost base by $210 million on a run rate basis. Our free cash flow increased nearly $400 million from 2022, and we reduced our leverage towards the middle of our target range while we invested in our business and returned capital to shareholders. We remain focused on positioning our business to capitalize on near and long-term opportunities to drive growth, profitability and cash flow. Our fourth quarter results reflect the diversity of our revenue base and the resiliency of our platform. At the consolidated level, fourth quarter fee revenue was $2.2 billion, a 2% decline from a year earlier. Adjusted EBITDA totaled $306 million, down 9% and reflected a margin of 14.3% compared with 15.3% a year ago. The $55 million incremental equity losses as well as lower transaction-oriented fee revenue and the timing of incentive compensation accruals were the predominant headwind to margin performance. Growth in our resilient revenue businesses, cost management actions during the year, and an actuarial benefit related to health care costs were partial offsets. Fourth quarter adjusted diluted EPS of $4.23 declined a more modest 2% as the adjusted EBITDA drivers and higher interest expense were largely offset by a lower effective tax rate. For the full year, consolidated fee revenue declined 11% to $7.4 billion. Adjusted EBITDA for the full year declined 40% to $737 million. Approximately 50% of the decline was from the adverse change in equity earnings, with the balance largely from lower transactional revenue. These items overshadowed resilient revenue growth and cost management actions. The full year adjusted EBITDA margin declined 500 basis points to 10%, including approximately 320 basis points from lower equity earnings. Adjusted EPS of $7.40 declined 52% with the adjusted EBITDA drivers as well as the adverse change in equity earnings and higher interest expense, partially offset by a lower effective tax rate. Moving to a detailed review of our operating performance by segment, beginning with Markets Advisory. The 3% decline in segment fee revenue in the quarter was mainly due to 5% lower leasing activity. Leasing fee revenue grew in the Asia Pacific region across most asset classes but was more than offset by softer leasing activity across most asset classes in the Americas and EMEA. Industrial leasing fee revenue was consistent with the prior year, which compares favorably to the 23% decrease in global industrial market activity according to JLL Research. Leasing fee revenue declined 15% for the full year, with largely consistent drivers as our fourth quarter commentary. As Christian described, we continue to see more sustained leasing demand for high-quality assets, which is favorable for our business mix. Our global growth leasing pipeline continues to hold up, and we are encouraged by the recent trends in the OECD's Business Confidence Index, which generally leads leasing activity by 2 to 3 quarters. Still, occupiers continue to delay leasing decisions, particularly for large-scale transactions. The contractual nature of leases, limited new office and industrial building starts, and our expanding pipeline provides optimism for long-term growth, though the timing and pace of acceleration and leasing activity is uncertain. Also within Markets Advisory, property management fee revenue grew 12% in the quarter and 11% for the full year, which both driven largely from portfolio expansions in the Americas and incremental fees from interest rate sensitive contracts in the U.K. Considering the current level of interest rates and the forward interest rate curve, the incremental revenue benefits from these contracts to the property management growth rate are likely to moderate as the deal progresses. The Markets Advisory fourth quarter adjusted EBITDA margin expansion reflected our cost management actions in 2023 as well as incentive compensation accrual timing. The lower leasing fee revenue, net of lower commissions, and higher incentive compensation accruals in 2023 drove the full year margin contraction, partially offset by property management fee revenue growth and our cost management actions. Shifting to our Capital Markets segment. Fee revenue declined 12% in the quarter and 28% for the full year as investor decision-making was prolonged by sharp interest rate increases and heightened volatility, along with elevated economic and geopolitical uncertainty. Our global investment sales fee revenue, which accounted for approximately 40% of segment fee revenue in the quarter fell 18% and compared favorably with a 24% decline in the global sales volume Christian referenced. Fee revenue declined across most geographies and major asset classes. However, we had several great spots in the Asia Pacific region highlighted by Japan. Our U.S. and EMEA investment sales go down from a year earlier, performed notably better than the respective region's market activity. For the full year, the 40% decline in investment sales fee revenue compared favorably with a 43% decline in market volume activity with EMEA notably outperforming the market. Our loan servicing fee revenue grew 3% in the quarter as lower prepayment fees tempered 6% growth of recurring servicing fees. For the full year, loan servicing fee revenue fell 3% as prepayment fees were approximately $13 million lower than the prior year, which masked 6% growth in the core servicing fees in 2023. The rise in interest rates has nearly eliminated early refinancing activity, which generates prepayment fees. The underlying increase in the servicing fees was driven by the continued growth in our Fannie Mae portfolio. The capital markets adjusted EBITDA margin contraction for the quarter and full year was predominantly driven by lower transactional fee revenue, net of lower commission expense as well as incentive compensation accrual timing. The decremental margin within capital markets for the quarter was a bit higher than typical, though the full year decremental margin was in line with the historical average and our expectations, considering the differences in geographic compensation structures and discrete items. The investments we've made in our capital markets talent and platform over the past several years position us to capitalize on a rebound in transaction volumes when market conditions improve. Looking ahead, the global capital markets investment sales debt and equity advisory pipeline is up modestly compared with this time last year and client engagement momentum has picked up over the past few months, which has coincided with the general recent stability of the 10-year treasury rate that is well below the October 2023 peak. The amount and pace of revenue growth over the course of 2024 will be heavily influenced by the factors impacting deal timing and closing rates that Christian described, so we anticipate higher growth rates in the second half of 2024. Moving next to Work Dynamics. Fee revenue growth of 8% in the quarter was led by an acceleration within workplace management. The 17% increase in workplace management fee revenue is a result of the ramp-up of the new global client wins and mandate expansions we secured earlier in 2023. For the full year, the ramp-up of the new contracts in the latter part of the year, drove 7% growth in workplace management fee revenue, which is on top of 15% growth in 2022. Project management grew 2% in the quarter from broad-based activity across geographies. Though demand moderated from prior quarters, generally in line with its historical [indiscernible] to leasing trends. For the full year, project management grew 9%. The improvement in Work Dynamics adjusted EBITDA margin for the quarter and the full year was primarily attributable to the revenue growth along with ongoing cost management. We remain confident on the segment's growth and margin trajectory over the coming years. Broadly, we continue to see solid new sales trends and strong contract renewal and expansion rates as the demand for professional management of corporate real estate increases. The new workplace management contracts from Fortune 100 companies we secured in the early part of 2023, will continue to support solid momentum through the first half of 2024, though at a more moderate pace than the latter part of 2023. We remain focused on securing additional project management mandates. However, the slower economic and leasing backdrop may dampen the near-term growth rates. Turning to JLL Technologies. Existing enterprise client demand drove 14% fee revenue growth, which was on top of a 21% year-over-year organic growth rate in the fourth quarter 2022. For the full year, 16% fee revenue growth followed 23% organic growth in the prior year. We continue to see strong retention rates of JLL Technologies Software and Solutions revenue. However, slower new client wins in 2023 will moderate growth rates in the near term. The combination of the fee revenue growth and incremental operating efficiency gains drove an improvement in JLL Technologies adjusted EBITDA margin that was more than offset by adverse changes in equity losses net of carried interest, both for the quarter and the full year. The timing of certain expenses was also a benefit to the fourth quarter margin. The equity losses resulted from valuation decline in certain portfolio investments and reflect a challenging environment for venture capital. Segment profitability remains the top focus, and we are pleased with the fourth quarter's positive margin contribution, excluding equity losses. Now to LaSalle. Advisory fee revenue declined 4% in the quarter primarily on the impact of valuation declines within our assets under management over the past year. Absent foreign currency exchange movements, assets under management were 7% lower than a year earlier, with approximately 70% of the decline attributable to valuation reductions with a balance from net acquisition and disposition activity. Capital raising activity and new capital deployment continues to be subdued given the evolving market environment, which also moderates transaction revenues. For perspective, new investments for the quarter and trailing 12 months were about 70% lower than the respective prior year period. Incentive fees, which are a function of the disposition timing and asset performance increased for the full year off a muted 2022 and drove 2% full year segment fee revenue growth. For 2023, we had about $25 million of equity losses from declining asset valuations as compared with a nearly breakeven 2022. The reduction in LaSalle's adjusted EBITDA margin in the quarter was largely attributable to lower revenue as well as timing of certain personnel costs and annual compensation accruals. The full year margin decline was primarily driven by the equity losses, partially offset by higher incentive fees. Turning to free cash flow. We recorded a net inflow of $389 million for the year compared with a $6 million outflow in the prior year. The improvement was driven largely by better net working capital including improved collection of trade receivables along with lower cash outflows associated with taxes paid and annual incentive compensation and commissions which outpaced lower cash from earnings. The lower cash from earnings was largely attributable to dampen transaction-oriented business performance. Cash flow conversion is a high priority, and we are very focused on net working capital efficiency. Shifting to our balance sheet and capital allocation. During the quarter, we strengthened our liquidity position through a $400 million bond offering with proceeds used to reduce our borrowings on our credit facility. Liquidity totaled $3.1 billion at the end of the fourth quarter including $2.7 billion of undrawn credit facility capacity. As of December 31, reported net leverage was 1.6x up from 1.0x a year earlier, primarily due to the adverse impact of noncash equity losses as well as lower cash earnings over the trailing 12 months. The equity losses had a 0.3x adverse impact on our fourth quarter reported net leverage ratio. Over the medium term, we intend to manage the business towards the middle of our 0x to 2x leverage range. With leverage above the midpoint of the target range in 2023, we selectively deployed capital towards growth initiatives and repurchased just $62 million of shares to offset stock compensation dilution as we prioritize deleveraging our balance sheet. Considering the seasonality and current leverage, we anticipate near-term share repurchases to continue at a pace that will offset expected full year stock compensation dilution. Looking further out, the amount of share repurchases will be dependent on the performance of our business, particularly cash generation and the macroeconomic outlook while also weighted against our broader investment opportunity set, in particular M&A. Regarding our 2024 full year financial outlook, we are cautiously optimistic that transaction activity will pick up in the second half of the year. Growth in our more resilient business lines remain solid. We continue to scale our platform and invest to both capture future growth opportunities and drive operating leverage. We are targeting a full year 2024 adjusted EBITDA margin, excluding equity earnings to be within a range of 12.5% to 14.5%. With many initiatives in play to drive growth and efficiency, we are excited about the value creation prospects of our business across market cycles. Before turning the call back to Christian, I'd like to note a few reporting changes we will make effective in the first quarter of 2024. First, JLL Technologies and LaSalle's equity earnings related to investment activity will be excluded from our adjusted EBITDA and adjusted net income calculation. Equity earnings from our operating joint ventures across the business will continue to be included. We believe this change will allow for clear visibility and better comparability of our operating financial performance across reporting periods. Second, we are aligning with sales assets under management definition to conform to industry standards, which includes uncalled committed capital and cash. Third, beginning next quarter, we will no longer report fee revenue or fee-based operating expenses following the conclusion of a comment letter from the SEC regarding the presentation of these metrics in our financial statements. We are working through alternative ways to provide the information and visibility we believe those measures bring. Importantly, this third reporting change is solely a matter of non-GAAP measure presentation. As there is no impact to the underlying performance of our business, our audited GAAP financial statements, adjusted EBITDA, adjusted net income or free cash flow. We will provide historical financial information that reflects all three reporting changes I just discussed prior to our first quarter earnings call. Christian, back to you.
