Thank you, John, for the question. Let me answer them one by one. So for you first question, our day one delinquency rate as you know is a real-time figure that we -- management internally used to monitor the situation on a daily basis. There is no direct formula that we can use to translate D1 delinquency to vintage or to our accounting provisions, but they're coordinated for sure. So when your day 1 delinquency increase from like 10% to 13% to the current 20%, it will give you a sense of the magnitude of the potential increase of our loss range. And, as we have started the elaborate agencies last year, when the portfolio side went down, if quantity delinquency rate typically will be degenerated as the higher quality borrowers pay off their loans and indeed and why the delinquent borrowers remain in the portfolio. So, we might continue to see a high level of D1 delinquency rate for the short-term survey. And for your second question, thanks for the keen observation, we had around 1.4 billion provision plus other credit losses in the fourth quarter. So as for the sufficiency of our prohibition, if you look at our slide, our coverage ratio for the M1 plus delinquencies, actually 1.6 times at the end up on the fourth quarter. However, we also believe that the impact of coronavirus on our loss rate in the first quarter is still material. Because when our users, stay in the home because of the virus, their willingness to repay and their ability to repay both get deteriorated. So that's why we see this 20% D1 delinquency in Q1 as well. And then, you'll start question regarding the strategy. As you know, our current leverage ratio is about 1.9 times, that at the end of 2019. So, we continue to deleverage in the first quarter where we will see a ratio even lower than that. We are among the most low levers players in the market, I believe, which will give us the ammunition at the right time when the credit cycle is gone and when we need to come back to market. So, we believe this is the only right course of action right now to stay low leveraged. We also mentioned that we will see freed up capital this year. That's true because although our revenues get recognized in one time, according to accounting rule 606 users, we actually get repayment from usage in cash this year. So our cash flow is kind of okay. We are assessing how to optimize our capital structure dynamically. So if the credit cycle gets away, when things gets normalized, we will utilize more into the lending business. If the credit cycle stays for a relatively longer period, we will utilize assets of cash to some short term or long-term investment ideas. And we also announced that buyback program out there. So it can it may also be used for the execution. Regarding the new investment ideas, as I mentioned, is still not material and very early and exploratory stage. We will make appropriate disclosure when things get material according to the listing rule. Thank you John again.
