Thanks, Guilherme. Good evening, everybody. Just -- if you notice any voice difference here because we are apart because of this coronavirus crisis. So moving to Slide 7, we present the evolution of our main operating KPIs; assets under custody, active clients and NPS. Our figures grew strongly in 2019 benefiting from the positive snowball effect generated through our brands, and investments made to enhance our platform and UX experience. Our AUC reached R$409 billion in December 2019, expanding 17% versus third quarter '19, and 103% year-over-year. The risk of mode of the markets in the fourth quarter '19 helped our AUC number, especially through the equity appreciation of our custody. It is important to highlight that without considering the market-to-market of our custody, we've kept a healthy base of net inflows during the fourth quarter, with an average around R$11 billion per month. Our second KPI, Active Clients, expanded 91% year-over-year to BRL1.7 million, reflecting solid performance across our channels and three retail brands. Lastly, XP ended the year with NPS of 73 highlighting the benefits of our self-reinforcing ecosystem for our clients. We will address the potential impact from the coronavirus crisis in our KPIs later during this call. On slide 9, we show our gross revenue evolution and it's breakdown across our businesses. 2019 total gross revenue was BRL5.5 billion, a 72% year-over-year increase. The growth in the fourth quarter '19 versus fourth quarter '18 was even higher, increasing 9% year-over-year from BRL957 million in fourth quarter '18 to BRL1.8 billion highs in fourth quarter '19. The main drivers or number one, mutual funds, especially performance fees in retail. Number two; equities and futures, in both retail and institutional businesses. And number three, I seek increase in issuer services revenue. In terms of revenue breakdown, retail remains our most relevant segment line representing 67% of total revenue versus 73% in 2018, with the Delta being mainly a function of the increase in issuer services from 5% to 9% of total revenue, reinforcing our diversified revenue profile and the benefits of our synergistic ecosystem. Moving to Slide 10, we see that 2019 was another outstanding year for the retail business. Following the strong AUC growth in macro tailwinds, retail revenue increased 56% year-over-year, reaching BRL3.7 billion. In terms of asset classes, as I rightly said in the previous slide. The main highlights were mutual funds, through performance fees in equity, and the hedge funds, and equities and futures trading which fallen higher overall volumes in between. Looking at our retail take rate. There was a twin bips contraction, each of 2019 versus 2018. From 1.4% to 1.2%, the decrease reflects, firstly, the zero brokerage fee strategy at our brand clear which is focused on power traders and was adopted in October 2018. Therefore, impacting results more meaningfully throughout 2019. The second factor was the steep increase in fee which was called by the stock market rally in large inflows in equities custody accounts without a corresponding growth in revenue. It is important to understand that concept when we think about a AUC and take away going forward. When we compare the take rate of the last 12 months in third quarter '19 with fourth quarter '19, it has been stable at 1.2%. We do not expect material change in the take rate going forward. And we will talk more about it when we address the coronavirus crisis impact in our KPIs On slide 11, we present our institutional and issuer services revenue segments, which also post strong results in 2019. Institutional revenue reaches BRL802 million in 2019, this represents an increase of 66% versus 2018. The growth was mainly driven by an increase in volumes of our Brazilian trading desks following the overall expansion in between [ph], and increase in secured placement fees with fixed income being the main contributor. Our institutional sales and corporate access teams have been very active in 2019, with more than 1,700 meetings organized during the year, and successfully connecting institutional clients to executives, industry experts, and politicians in Brazil. Additionally, it is important to highlight our efforts and investments to continually qualify our institutional team in building strong, long-term relationships with international clients. It is worth noting, we recently added [indiscernible] as Chief Strategy and Head of Research coming from Longo where he used to work for Merrill Lynch, and Fabio Fisher as Head of Equity Sales in New York, also coming from Credit Suisse in New York. On insured services, revenue totaled BRL507 million in 2019. The growth relative to 2018 was 185%. The main highlights of the year were in order of contribution. One DCM, net debt to market, our main revenue stream which is very recurring in nature and resilience through market cycles; two, reach offerings, and three ECM, equity capital markets. Now moving to slide 12, we show our digital content and other revenue. Digital content revenue reached BRL112 million in 2019, up to 108% year-over-year. The result was mainly driven by the increasing sales of online educational products through our XP educational portal. During the order, we also launched a speech, a retailed-folk independent research house that enhance our high quality content. We believe this revenue segment will continue to grow in 2020 but more importantly, is a differentiated to connectors with our customers in times like the one we're leaving right now, more about that later in the presentation. Other revenue grew 180% in 2019 verse 2018, and total BRL420 million. This is mainly related to all the market makers, and better form growth, enabling our ecosystem to function well. Next, on Slide 13, we present our COGS and in operating expenses analysis. COGS which is mainly IFA commissions in clearing house fees reached BRL1.6 billion in '19 versus BRL491 million in '18, representing a 71% growth rate, just in line with our revenue growth. Gross margin expanded 50 basis points in 2019 to 68.7%, basically due to product mix. Moving to operating expenses, there was a 44% annual increase in 2019. As a percentage of net revenues, expenses decreased from 42% in 2018 to 35% in 2019, reflecting the benefit of our operating leverage. On Slide 14, we present adjusted net income, which reached BRL1.1 billion in 2019, growing 119% from BRL491 million in 2018. Adjusted net margin expanded from 16.6% in '18 to 20.9% to '19, above the midpoint of our guidance of '18 to 22% range. In conclusion, 2019 posted strong numbers across all segments of our ecosystem. And I would like to reinforce our long-term commitment and goal of growing our businesses while maintaining a high level of profitability. Now, I'm going to talk about our new businesses, and the potential impact of the coronavirus in our numbers going forward. Moving to Slide 16; here, we present a roadmap for new businesses. Most of it is related to the concept of providing our investor customers a full service platform, including banking services, such as a digital bank account, payments, debit and credit cards; so our clients can cut completely the link with income and banks, and we can grow our share of wallet. Despite the crisis, we understand these initiatives create long-term value for XP, and we are moving forward as planned. But we know it is important to be flexible, agile, and evaluate the scenario as the clients evolve. Regarding our debit and credit card initiatives, we are thrilled to announce our partnership with Visa as the issuer partner of our cards, which we plan to launch still this year. We found in Visa, the best partner in the card segment as they bring a blend of superior services with scale and a global acceptance footprint to all our customers. We are confident that the combination of our investment and financial digital services with the new cards to be launched with Visa will further enhance the experience of our clients. Other highlights worth mentioning and I already talked about it quickly is that it's big business, run by Luciana Shabda [ph], which is an independent provider of investment content, as already said, needed more than ever in times like this. Now we are going to talk about our view of potential impact of COVID-19 crisis in our business. Moving forward to Slide 17; here, we analyze the potential near-term impact to our businesses related to the coronavirus crisis. It is important to highlight that these are management's opinion and not facts for sure. And we are in that early stage of this crisis in Brazil, so it's hard to make any forecasts. Having said that, in terms of assets under custody, the steep decline in the stock market, of course, negatively affects our equity position, but not necessarily the net inflow, and that's very important. We believe to be at a very early stage of this crisis, as I said, to conclude if this is positive net flows are going to compensate or not for any drop down in the stock market regarding our AUC at the end of this year. Now moving to product mix on the right, up right on the slide. If we compare with what happened in past crisis, we should expect to see rise in demand for fixed income products due to recent market sell-off. The difference nowadays, though, is the all-time low interest rates in Brazil, around 4% per year and maybe going down even further. Our customers will have to invest in something and we will be there to help them and get through these hard times. When we talk about net inflows on the bottom of the left side of the slide; it is our expectation that it will keep a positive trend. But again, it's hard to say if the pace of growth will diminish or not going forward. Up to now, we haven't seen a major change in our net inflows, except for few clients with large equity custody, but without necessarily causing any impact on revenue. For example, all the clients with more than BRL1 billion of equity custody in our platform, as of today, represent in aggregate less than 10% of our total custody but generate less than 0.1% of total revenue. So, this led us to the take rate. If the AUC suffers from redemptions from large equity positions that do not provide revenue, like the example I just gave, our take rate should go up, just analyzing this factor. If there is a shift in mix towards fixed income, which is possible, it will depend despite equities having in general a higher take rate than fixed income. The later has a much bigger market, lower churn, and usually upfront fee payments. Again, under these uncertainty scenario we are facing it's too early to tell how our take rate is going to behave in 2020. Although we understand this is a different crisis, just to try to give you some additional color, we highlighted in the next slide what happened in our KPIs in past crisis in Brazil. Moving to the Slide 18; we picked here three episodes in Brazil: 2014 elections, [indiscernible] in 2017, and the truckers strike in 2018. In all of them despite the drop in the equity market, our AUC and net inflow performed well. As any portfolio manager understands, of course, I do not have to say that past performance is not a guarantee of future performance. But I guess, the point I'm trying to make here is the form. Number one, we need to be nimble, agile, adaptable, and learn quickly from the crisis. Number two, our business tends to be less affected by the crisis than other businesses since it is largely digital and less dependent on logistics. Number three, we still see a massive, long-term opportunity in front of us, again, with 90% of the BRL8.6 trillion addressable market is still concentrated mainly in five banks. And number four, the competitive environment remains unchanged. We believe our platform is positioned better than ever to overcome this crisis, and we have the opportunity one more time to differentiate ourselves from the incumbents. Remember, we are focused on investments with a unique IFA network close to our customers, there is a huge difference in our view, especially in times like this. Moving to Slide 19; you can see as Guilherme presented in the beginning, XP's strong cash position, especially after the IPO and our extended debt maturity. We have more than R$7 billion in cash and only BRL0.4 billion of debt maturity in 2020. From a cash point of view, we are in a comfortable position in situation to navigate through this crisis. Regarding our risk metrics, we follow daily, our varn [ph] and a stress test among other metrics, and both have behaved well despite the increase in volatility. We do hedge our positions to protect our book of flows as market makers. And just to give you a sense, as of yesterday, our varn [ph] one day and 95% of confidence representing 0.08% of our net worth, and our stress test represented 0.79% of our net worth; all well below the targets we have established in our company. Now let's move to my last slide and talk about some opportunity we understand this crisis bring to us as any enterprise. So in Slide 20; it is our belief that every crisis is an opportunity to get closer to customers, and that is exactly what we have been doing. In this context, we benefit from our financial education DNA in digital content platform. Since the outbreak of the coronavirus crisis, our strategist, research analyst and digital influencers have intensified the publishing of reports and broadcasting of videos. We have been increasing the touch point with our clients. To-date, more than 30 reports in live were posted about the crisis with more than 600,000 views. We also published daily market open and closed live videos in post using not only the main social media channels, but also our proprietary investment portal InfoMoney [ph], our own TV network and XP Education. As shown in the charts on the right, the number of interactions and views increased sharply these months reflecting our communication efforts. Through the first half of March, we already had nearly the same level of traffic on our research platform as in the entire month of February. Informatics traffic also remains high with more than 5 million visitors through March 13. Again, education is in our DNA and we believe information to keep them in periods like the one we're going through right now. Lastly, as Guilherme mentioned, the total addressable market remains huge, our partnership keeps focused on the long-term, we believe the company is stronger than ever to go through the crisis. And if necessary, we will adapt quickly. On behalf of XP, I'd like to thank you all for your interest. And now, we will open the call for the Q&A session. Thank you very much.
