Thanks, Tony, and good afternoon, everyone. Throughout our history, we've been laser-focused on our four core constituents: merchants, consumers, Dashers and our employees. And today, we are excited to welcome our fifth constituent, our shareholders. I want to take this opportunity to share how we manage the business and allocate capital. We are still early in our life cycle and believe we have substantial growth opportunities ahead of us. We intend to invest aggressively to pursue these opportunities. When navigating capital, we start small and experimented the refined product market fit. If we see strong demand with the path to unit economics and meet our thresholds, we invest incremental capital. Each project we invest in must continuously earn capital on its own merits. To date, the bulk of our investments have been made through our income statement rather than through our balance sheet, and we expect this to remain the case for the foreseeable future. We are the category leader in the U.S., but despite our scale, we see significant room for growth. Consequently, we are managing the business to maximize scale and long-term profit dollars rather than take rate or margin percentages. Impact is, this means we intend to invest aggressively into the business in order to further our growth initiatives and expand our competitive advantages. As you likely saw, we intend to provide guidance for Marketplace GOV and adjusted EBITDA going forward. We do not plan on guiding to revenue as we do not directly manage the business to this metric. In our model, revenues and output, reflecting in part dynamic decisions we make around consumer pricing, the ideal mix of advertising to promotions, our relative success with DashPass and the mix of Drive volume. We focus intently on inputs in each of these areas but will manage the business to Marketplace GOV and adjusted EBITDA dollars. We provided our guidance for Q1 and 2021 in our investor letter, but I'd like to provide a little more detail behind that. Underlying our 2021 guidance is an assumption of accelerated market reopening and a return to in-store dining. While we have seen many positive signals from consumers and markets that have temporarily reopened during the pandemic, we acknowledge that vaccination and full reopenings could drive sharper changes in consumer behavior than current data would predict. Consequently, our 2021 full-year guidance reflects this uncertainty. We are deeply hopeful that markets will reopen soon and we'll manage our business to provide exceptional experiences to merchants, consumers and Dashers in any scenario. With that, I'll open it up to questions.
