Well, great. Thank you, Keith. And Keith, I can't thank you enough for your partnership, your leadership, your friendship and your support since I joined the company. Fiscal 2020 was another important and busy year for Salesforce. We launched one of the most significant product initiatives in the company's history with Customer 360. We acquired Tableau, the largest acquisition in our history which enables our customers to see and understand data. We welcome Salesforce.org expanding our vertical strategy. We unveiled and expanded several strategic partnerships including AWS, Microsoft and Alibaba to better serve our customer. And we accomplished all this while sustaining organic top line growth and producing another year of strong financial performance driven by our values, our discipline and our focus. Here are a few of the financial highlights for Q4 and fiscal 2020. Q4 revenue grew 35% in dollars and 34% in constant currency. Excluding the impact of Tableau and Salesforce.org, Q4 revenue grew 22%. For all of fiscal 2020, revenue grew 29% in dollars and 29% in constant currency. Excluding the impact of Tableau and Salesforce.org, fiscal 2020 revenue grew 23%. Q4 CRPO grew 26% in dollars and 27% in constant currency, and again, excluding the impact of Tableau and.org, Q4 CRPO grew 20%. Our portfolio of industry-leading products continues to deliver strong year-over-year subscription and support revenue growth in Q4. Sales Cloud grew 17% or approximately 14% excluding the contribution from Salesforce.org. This compares to a year-over-year growth rate of 11% in Q4 of last year. Service Cloud grew 26% or approximately 22%, excluding the contributions from ClickSoftware and Salesforce.org and this compares to a year-over-year growth rate of 22% in Q4 of last year. Platform and other grew 74% or approximately 30%, excluding the contribution from Tableau and Salesforce.org and this compares to a year-over-year growth rate of 54% in Q4. Keep in mind; last year's results included revenue from the acquisition of MuleSoft. And Marketing and Commerce Cloud grew 28% or approximately 24%, excluding the contributions from Salesforce.org. This compares to a year-over-year growth rate of 34% in Q4. Again, keep in mind the Marketing Cloud revenue benefited from the acquisition of Datorama. So while M&A benefited the growth rates for each of the clouds year-over-year, our organic growth rate by cloud remains very strong and have even accelerated year-over-year in some cases. Lower revenue attrition also continued to support our growth in Q4 and for the full fiscal year with dollar attrition continuing the downward trend we have seen for the last several quarters. And I'm very pleased to share that the revenue attrition for the year is now currently below 9%. This is a historic low for Salesforce. This continuous improvement reflects the ongoing shift of our business mix to enterprise and the international markets, which inherently have longer contractual relationships and lower attrition rates. Turning to operating margin. Q4 non-GAAP operating margin was 15.4%, down 110 basis points year-over-year. As discussed last year, our Q4 non-GAAP operating margin reflects the timing of Dreamforce in Q4 versus Q3 last year as well as the timing of integration and other investments in Tableau. For the full year we delivered non-GAAP operating margin of 16.8% down 24 basis points year-over-year, but coming in higher than our expectation largely due to the overall revenue outperformance. Excluding the impact from M&A, our organic non-GAAP operating margin is consistent with our initial guide from last year of approximately 125 to 150 basis points. Q4 GAAP loss per share was $0.28 and this loss was unfavorable compared to our expectation due to the incremental tax cost associated with integration of acquired operations and assets. Q4 non-GAAP earnings per share was $0.66. Turning to cash flow. We had very strong cash collections in Q4 which drove operating cash flow of $1.6 billion, up 23% year-over-year. For fiscal 2020, we delivered $4.3 billion of operating cash flow, up 27% over last year. CapEx for this year was $643 million. We continue to see scale benefits from CapEx with CapEx as a percent of revenue now approximately 4% and that's down from 4.5% of revenue last year. Free cash flow defined as operating cash flow less CapEx was $1.5 billion in Q4, up 29% over last year. And for fiscal year 2020, free cash flow grew 32% year-over-year to $3.7 billion. Remaining performance obligation representing all future revenues under contract ended Q4 at $30.8 billion, up 20% year-over-year. Current RPO which is our business that is billed and unbilled and expected to be recognized as revenue in the next 12-months was $15 billion, up 26% year-over-year with Tableau and Salesforce.org contributing approximately six points of growth to this amount. Before I move on to guidance as Marc described, we're excited to be expanding our industry offering with the acquisition of Vlocity. We are acquiring Vlocity for approximately $1.33 billion in cash net of Salesforce's ownership in the company. The transaction is expected to close during the fiscal second quarter and we expect approximately $50 million in revenue contribution during fiscal 2021. Additional details in the transaction can be found in our recently filed 8-K. Now turning to guidance. As a result of our Q4 performance, we are pleased to raise our Q1 revenue guidance by $50 million to $4.875 billion to $4.885 billion or 30% to 31% growth year-over-year. We're also raising our fiscal 2021 revenue guidance by $200 million to $21 billion to $21.1 billion or approximately 23% growth year-over-year. With the advantage of our predictable and recurring revenue model along with our expanding product portfolio and an increasing traction in enterprise and in our geographies as Marc mentioned, we remain on track to deliver $34 billion to $35 billion in revenue in fiscal 2024. This long-term target represents a four year CAGR of approximately 20% at the high end of the range and is consistent with the durable growth we've been delivering year after year. For Q1, our fiscal 2021, we expect to see CRPO growth of approximately 23% to 24% year-over-year. We expect to deliver fiscal 2021 non-GAAP operating margin of 18.1% which represents approximately a 125 basis points of expansion year-over-year driven by continued improvements in organic operating leverage which is partially offset by the margin headwinds and tailwind related to recent M&A. We expect fiscal 2021 operating cash flow growth of approximately 20% or better than $5.1 billion, which reflects continued strong cash generation, partially offset by the cash headwinds from the acquisition of Tableau. For fiscal 2021, we anticipate CapEx to remain at approximately 4% of revenue. We expect fiscal 2021 GAAP alluded EPS of $0.12 to $0.14 and non-GAAP diluted EPS of $3.16 to $3.18. Now our GAAP and our non-GAAP EPS assumes that OIE is a net expense of approximately $5 million for fiscal 2021 and our non-GAAP tax rate of 22% which is down approximately 50 basis points primarily due to higher projected research and development credits. Please recall that our OIE and EPS guidance assumes no contribution from mark-to-mark accounting as required by ASU 2016-01 and lastly as a reminder the full financial impact of velocity acquisition is factored into our guidance today. To close, we've delivered another year of strong financial performance highlighted by organic, durable, top line growth and excellent cash flow generation. Further in a year where we closed the largest acquisition in our history and further expanded our products and industry offerings, we are pleased with our ability to deliver a consistently reported non-GAAP operating margin percent. This level of sustained and balanced growth at our scale is unprecedented in enterprise software industry. Closing, I'd like to thank our employees, our customers, our partners and our community and our shareholders for their continued support. And with that let's open up the call for questions.
