Thanks Bob. Turning to Slide 8, our advisory services segment fee revenue and adjusted EBITDA fell about 31% and 50% respectively, as expected significant weakness in our high margin, but cycles sensitive sales and leasing businesses drove the declines. Our advisory adjusted EBITDA margins fell to around 10%, which was impacted by revenue compression about right million and incremental COVID related expenses and 11 million for the companies donation to a COVID relief fund. Together these items reduced the advisory margin, approximately 140 basis points from the quarter. Global leasing revenue declined about 38% as the pandemic negatively impacted our largest markets in the quarter, in the U.S. continental Europe and the UK, which collectively comprise over 80% of global leasing revenue decreased 43%, 25% and 20% respectively. Greater - global leasing this quarter achieved 14% growth following a 26% decline in Q1. While there was pressure across all property types in the quarter, industrial was resilient with leasing revenue declining just 10%. We saw similar pattern in property sales with global revenue down 48% and declined 26% in continental Europe, 51% in the U.S. and 76% in the UK. Notably we improved our U.S. market position significantly with 160 basis points share gain. Our 17.6% share for the quarter is 860 basis points more than our closest competitor. Like leasing, we saw a rebound in greater China with property sales climbing 46% after decreasing over 70% in Q1. Commercial mortgage revenue fell 28% as most capital sources pulled back from lending. We did however, see an increase in activity from banks with a strong appetite for offer an industrial project. The selling of credit markets that began in the second quarter has extended into July. Other advisory services business lines were less impacted by COVID during the quarter. Advisory properties and project management revenue fell about 8%, driven by the temporary shutdown of construction activity and reduced spending on capital projects. Valuation revenue fell about 12% with modest growth in EMEA and our APAC market. Finally, loan servicing revenue grew 15% as our portfolio reached 245 billion, our multifamily properties which comprise nearly half of our global servicing portfolio, and more than two-thirds in the U.S. is proven to be resilient during the pandemic. We have just a handful of loans in forbearance and have not received a new request since May. Turning to Slide 9, our global workplace solutions segments saw lighter than usual revenue performance, but strong growth in profitability. Facilities management which accounts for more than 85% of the segments fee revenue, and is a contractual business saw 7% growth. This was offset by more cyclically sensitive project management and transaction services, which together posted a 33% fee revenue decline. Even with lower contributions from these higher margin revenue sources, and 17 million incurred for COVID related expenses and three million for the COVID Relief Fund. GWS's adjusted EBITDA margin on fee revenue expanded more than 170 basis points to 15.4%, leading to adjusted EBITDA, growth of more than 11%. This is the highest quarterly margin ever for the GWS business and our performance was driven by proactive cost management. We sustained a high contract renewal rate in the quarter, and the new business pipeline continued to increase from your end levels. COVID logistical challenges continue to hamper and prolong the contracting and on-boarding processes. Yet, after a pause at the onset of the COVID crisis, companies are beginning to move ahead without sourcing plans as they seek to capture efficiencies in a constrained economic environment. GWS is also a well diversified business, serving clients across a wide array of property types and industries, including many deemed essential during the current crisis. We are very proud of the work our GWS team continues to do supporting our clients during this challenging time. Turning to Slide 10. Our real estate investment segment adjusted EBITDA came in at 18 million down 41%, it included incremental COVID expenses and the relief fund donation allocation, which together totaled about $2 million. Investment management was a standout performer with adjusted EBITDA rising 62%. This reflected strong growth and recurring asset management fees, AUM increasing three billion from a year-over-year period, as well as higher carried interest in co-investment returns partially offset by lower acquisition, incentives and disposition fees. Our focus on core and corporate strategies is highly advantageous in the current environment. Capital raising remains elevated totaling 11.4 billion over the past 12-months. As Bob mentioned, U.S. development is well positioned entering the downturn. Although adjusted EBITDA fell about 55% this is largely due to deal timing. We continue to be optimistic about second half performance as their in process activity stands at 13.7 billion. About half of that activity is comprised of fee development and built-to-suit and the remaining assets are well-capitalized with strong equity partners. Our development business in the UK incurred and adjusted EBITDA loss of 11 million during the period. This loss is largely attributable to transitory operational challenges due to COVID-19, including temporary construction, stoppages and other challenges, as well as constrained sales activity. We expect performance to improve now to construction and commercial activities have largely resumed. Lastly, the 9 million adjusted EBITDA loss in our enterprise focused co-working solution Connor was in line with Q1 performance. Connor's results in the period were impacted by mandated shutdowns and elevated costs to ensure the safety of occupants as units reopened. Let’s now take a look at our 2020 outlook on Slide 11, given the continued uncertainty about COVID-19 trajectory and its impact on the broader economy we will again, refrain from providing explicit EPS guidance. However, we will discuss our expectations for the remainder of 2020 in detail. Starting with the advisory services segment, where our revenue declined was shallower than we expected in the second quarter. We now expect the recovery in our transaction businesses to be more gradual and drawn out. We expect revenue decline in Q3 and Q4, to be similar to that of Q2. With relatively better performance outside of the Americas. Sales and leasing revenue were off significantly in the quarter, benefited from robust pipelines built before the COVID crisis. Future performance is highly dependent on pipeline replenishments, and we are tracking signed confidentiality agreements and other leading indicators to inform our expectations for the remainder of the year. For the rest of the advisory business combined, we expect to mid to high single-digit revenue decline. Variable costs which comprise about half of our advisory cost structure are expected to decline a bit more than overall revenue. We anticipate a modest mid single digit decrease in advisory fixed costs, as it typically takes longer for our actions in this area to show an impact. Moving to GWS. We expect gross revenue to rise in the mid single-digit and fee revenue in the mid to high single-digits with growth in contractual facilities, management revenue offsetting an expected decline in GWS transaction revenue. As a result of disciplined cost management we also expect to achieve modest margin expansion, which will drive high single-digit adjusted EBITDA growth. This growth rate includes an expected headwind from COVID related items in the mid single-digit range. Our outlook is also premised on slower growth and facilities management revenue as we face tough compares in Q3 and Q4, when facilities management achieved growth of 15% and 18% respectively. Our first half results benefited from the high level of client on boarding in late 2019 that drove the strong prior year growth rate. Simultaneously while the logistical challenges of contracting and on boarding clients are slowly receding, we did not bring on new clients during the first half at the same pace as last year. This is expected to weigh on growth in Q3 and Q4 and we would expect growth to resume to double digit levels once these new clients’ transitioned delays abate. Looking at REI, we continue to believe our core legacy business line global investment management and U.S. development are well positioned for the current environment and we anticipate more resilient performance than during the last downturn. In Investment Management, we expect adjusted EBITDA growth in the mid teens range. As higher return adjusted EBITDA, is offset by lower contributions from Net Promote as dispositions flow and lower co-investment returns. We expect U.S. developments to contribute similar adjusted EBITDA as in 2019, as investors continue to have an appetite for high quality assets. At present nearly 80% of our in-process portfolio is comprised of healthcare, industrial and multifamily properties and office properties are 90% leased. We expect UK multifamily residential development to generate sequentially improved the adjusted EBITDA in each of the remaining quarters and be about breakeven for the year. Construction resumed during May and we remain confident in the long-term trajectory of this business, given the housing shortage in the UK and our robust pipeline of new projects. Similarly, we continue to believe in the long-term rationale for investment in Hana. But expect to incur a larger adjusted EBITDA loss in 2020 than in the prior year. This is primarily the results of additional units being brought online in 2020, as well as revenue delays due to COVID-19 related shutdowns, and longer new unit development period. Longer term, we see an opportunity for accelerated transition to an asset light investment model, partly catalyzed by dislocations in the flex space market. Turning to Slide 12, our financial position has continued to strengthen despite the challenges of COVID-19. We ended Q2 with just 0.6 turns of leverage, down 0.2 turns from a year-ago and 3.5 billion of liquidity, an increase of half a billion from the year ago period. In addition, we have no debt, maturing until 2023. Given the uncertainty around the virus' trajectory, and its impact on economic activity, we will continue to prioritize liquidity over discretionary capital deployment. Once we have more confidence in an economic recovery, we will resume deploying discretionary capital in line with our capital allocation strategy. In the meantime, we are continuing to prioritize investments in our people and platform and selective M&A. Our key focus will be companies that enhance the diversification of our service offerings and resiliency of the overall business by increasing the scale of less cyclical business lines. Finally, we view our share price is highly attractive at current levels and could resume repurchases when appropriate if we are unable to identify suitable and properly priced acquisition opportunities. While the environment remains highly uncertain, we are confident that our business and our capital structure are positioned to not only weather the challenges presented by COVID, but build on our industry leadership position and maximize long-term earnings growth. With that, I will ask you to turn to Slide 13, as Bob provides a few closing thoughts.
