Good morning, everyone. And welcome to our second quarter 2020 conference call. I hope everyone is safe and healthy during these difficult times. Joining me today this morning are Leeny Oberg, Executive Vice President and Chief Financial Officer; Jackie Burka McConagha, our Senior Vice President-Investor Relations; and Betsy Dahm, Vice President-Investor Relations. I want to remind everyone that many of our comments today are not historical facts, and are considered forward-looking statements under federal securities laws. These statements are subject to numerous risks and uncertainties as described in our SEC filings, which could cause future results to differ materially from those expressed in or implied by our comments. Statements in our comments and in the press release we issued earlier today are effective only today and will not be updated as actual events unfold. Please also note that unless otherwise stated, our RevPAR and occupancy comments reflect system-wide constant currency and year-over-year changes, and include hotels temporarily closed due to COVID-19. You can find our earnings release and reconciliations of all non-GAAP financial measures referred to in our remarks today on our Investor Relations website. The lodging industry continues to be profoundly impacted by the COVID-19 global pandemic, and the current operating environment remains quite challenging. Second quarter worldwide RevPAR was down 84%. While April fell 90% the toughest year-over-year comparison on record. Demand has risen steadily since then. RevPAR declined 85% in May, 78% in June; and 70% in July. Many of our hotels that were temporarily closed due to COVID-19 have now reopened. Today, 9% of our global properties remain closed compared to more than 25% in April. Since April occupancy level have increased each month in every region around the world albeit at varying rates. Global occupancy in July hit 31% for all hotels, increasing 19 percentage points from April. And occupancy in July for the hotels that were opened for each of the last fourth months, reached 39%; growing 23 percentage points over that period. There is still no visibility around when RevPAR could return to 2019 levels; however, the global industry trends experienced over the last couple of months give us confidence that people will continue to increase their travel. We are optimistic that second quarter will mark the bottom and the worst is now behind us. Greater China which represents 9% of our rooms, over 90% of which are managed is leading the recovery, and has seen rapid improvements in occupancy and new bookings. With the virus mostly contained at this point, many domestic travel restrictions have been lifted; and the number of daily passenger domestic flights is now around 80% of pre-COVID levels. While leisure and drive-to-destinations led the initial recovery; it is encouraging to see business transient as well as group also picking up nicely. Occupancy levels in Greater China have reached 60%, up significantly from the single digit levels in mid-February; and much closer to the 70% we saw at the same time last year. RevPAR has followed a similar trajectory; after declining 85% year-over-year in February, RevPAR in Greater China improved to down 34% in July; averaging over 10 percentage points of improvement per month. At the current rate of recovery and assuming no wide resurgence of COVID-19, the Greater China market could approach 2019 occupancy and RevPAR levels as early as next year, even assuming limited international guests. In 2019, nearly 80% of its room nights were sourced from guests within China. Trends in the rest of Asia Pacific are improving at a slower pace as countries are in various phases of reopening and as certain borders remain closed. But the recovery of travel in Greater China demonstrates the resiliency of demand once there is a sense that the virus is better under control, and restrictions can be safely lifted. In North America 96% of our hotels are now open. We are experiencing a steady recovery across all chain scales, although the rate of recovery within markets and by hotel type has varied tremendously. In 2019, domestic travelers accounted for 95% of North American room nights, a benefit in the current environment. Leisure demand has been strong in resort areas, as well as in secondary and tertiary drive-to-markets; not surprisingly our extended stay hotels have experienced the fastest pace of recovery. New bookings in North America have been building nicely led by near-term leisure transient reservations. Despite the recent surge in cases in some states, consumers are increasing their travel. While U.S airline passenger traffic is still well below last year's levels; the number of air travelers the last two weeks of July has more than triple -- was more than triple they are in the first two weeks of May. And system-wide North America RevPAR continued to improve in July to a year-over-year decline of 69%, which is seven percentage points better than June. Historically leisure has made up roughly one-third of our total room nights in North America. The more interesting part of this statistic is that the monthly variance in that percentage is actually quite small. In 2019, the estimated proportion from leisure was around 36% during the summer, and only declined to 32% in September and October. We expect that solid leisure demand will continue through Labor Day in North America and could continue into the fall, as employers and schools alike operate remotely. Business transient in group demand in North America while lagging are showing very early signs of improvement. For now the group bookings outside of those associated with our caregiver and first responder programs tend to be mostly smaller ones such as weddings or travel sports teams. Our Europe, Middle East and Africa region or EMEA and our Caribbean and Latin America region or CALA posted the lowest occupancy levels and steepest RevPAR declines in the second quarter. Severe restrictions following rising rates of COVID cases in many countries combined with a much higher dependence on international travelers in these regions have suppressed demand in these regions. In 2019, the percentage of room nights from international travelers was around 40% in Europe, 50% in the Middle East and Africa; and 60% in CALA. 75% of our hotels in EMEA and 70% in CALA were closed for most of the second quarter. Trends in both regions have started to improve recently as the prevalence of cases drops and border restrictions ease. Many of our hotels in these regions are welcoming guests again with under 30% remaining temporarily closed. On the development front, owners are showing great interest in our brands with Greater China again out in front. Greater China contributed nearly one-third of deal signings in the first half of the year with the entire Asia-Pacific region accounting for roughly half of all signings. Owners in the region are taking a long-term view on the market. Year-to-date, we have signed 30% more deals in Asia Pacific than we did in the first half of 2019. The pace of signings is not as robust in other regions around the world largely due to the lackluster lending environment and owner uncertainty. We cancelled one of our monthly deal approval meetings in the spring, which reduced our signings year-to-date, but we are having productive conversations with owners and franchisees, who want to move forward. Some are hoping to see lower construction costs in the weaker economic environment for new builds, while others are interested in conversions to our brands. Our pipeline totaled approximately 510,000 at the end of the second quarter with over 230,000 rooms under construction or around 45%. The pipeline is 1% lower than at the end of the first quarter with the slowed signings and a few more projects than usual put on hold. While construction activity has resumed in most parts of the world, we still expect some openings will be delayed due to slower construction timelines and supply chain issues related to COVID-19. There is uncertainty surrounding future worldwide room's growth, but given current trends; we could see net room's growth between 2% and 3% in 2020. The final result will depend a great deal on the way the pandemic plays out around the world in the remainder of the year. Over the last several months, we have enhanced our liquidity position and materially reduced our cost structures at both the corporate and property level. We are in constant dialogue with our owners and franchisees, and are working together to navigate these extremely challenging times. As demand returns, we are adjusting our operating protocols and ramping up our business in a thoughtful way. First and foremost, we are focused on the health and safety of our associates, and guests and on communicating these important efforts. We continue to enhance our cleanliness guidelines to meet the health and safety challenges presented by COVID-19. We have mandated that all hotels have electrostatic sprayers to help quickly disinfect public areas, and all properties must submit a monthly commitment to clean certification. And we are increasingly leveraging technologies like mobile check-in, mobile key; and mobile chat between guests and hotel associates to reduce face-to-face interactions, while amplifying operational efficiencies. Additionally, we've announced that guests are required to wear face coverings in the public spaces of our hotels in the Americas, a policy that is also currently in place for associates globally. We are stepping up our marketing efforts around the globe as demand improves. Each region is carefully monitoring social, economic and travel trends, and implementing a phased-in approach based on local consumer sentiment and travel intent. With over 143 million members globally, Marriott Bonvoy, our award-winning Global Loyalty Program underpins all our marketing strategies. We remain focused on engaging our members with targeted email campaigns, and various promotions; such as points accelerators on our co-brand credit cards for gas, dining and groceries; gift card discounts and our current Bonvoy boutiques is sweepstakes for items like bedding and robes. For elite members, we have extended their status through early 2020, and in June credited their accounts with a one-time deposit of elite night credits; allowing them to reach the next tier faster. Before I turn the call over to Leeny, I must take a moment to say how proud I am of our incredible team of associates around the world. This has been a time of tremendous stress and uncertainty yet our teams continue to impress and inspire me. I also want to comment on the current social justice movements. As we said in our recent statement, we stand against racism. We believe that racism must be eradicated. Our company believes in equality, justice and putting people first no matter what they look like, here they come from; what their abilities are or who they love. My management team and I are deeply committed to building on our historic commitment to diversity, and to do more to champion diversity, equality and inclusion; both within our company and within the broader community. In closing, while this was by far the most challenging quarter in the history of our company; I am pleased with our progress. I believe we can look forward to a brighter future for travel and for Marriott. With our unparalleled portfolio of 30 global brands, superior loyalty programs; strong liquidity position and the best team in the business, I am optimistic about the trajectory of our business in the months and years ahead. And now Leeny, who has ably led our finance team to buttress our liquidity and to set Marriott up with the strength it needs to survive this crisis, will talk more about our financials. Leeny?
