Perfect, Mario, good to see you. Regarding the income tax rate, you're right. We gave the earnings before tax margin guidance. And we know that the accounting income tax rate is tricky depending on the mix of revenue. But that's exactly why we have this I would say wider range in terms of the net income from 3.8 billion to 4.4 billion. We have many different assumptions here. So I cannot give you a specific what we use to give this guidance, because it depends from the range. What I can tell you is we're confident that we can deliver the bottom of the range. And one simple math here to help you out is the following. Imagine that we are in 2022, the whole year, so R$14 billion revenue, R$3.6 billion of net income. We would have instead of 5.6, R$5 billion of SG&A, right, R$600 million of reduction in expenses would mean more than R$300 million additional to net income. So with that, we would be able to reach the bottom of the guidance. Of course, as I answered the previous question, the year started in a very tough way, because of what happened with Americanas and its capital markets activity and so on. But we do not expect the market to stay, I would say dysfunctional throughout the whole year. So capital market activity should resume at some point, the companies need to roll over their debt. We have several investments in fixed income that mature around this year. So all of that factored in is what gave us the confidence with that. So I don't have a specific income tax rates to give you. Your second question about the headcount. You mentioned the 5.5, the 5.5 reduction is only comparing January to December. But what I would -- I would say two things here. Number one, yes, you can expect further reductions, that's going to be -- the efficient theme is going to be constant throughout the whole year. But most important than paying attention to headcount is to pay attention to SG&A, right? Because we can have, for example, in third quarter last year, just to give you an example, third quarter last year, our headcount growth went up. We had a growth in headcount compared to the second quarter. But we had a lot of interns and young developers that we had a partnership with that we bring -- brought in the company. And that's a different structure of layer. So, the transformation, the benefit of the transformation ongoing is exactly to have less span in layers, to have merge of leadership, to simplify. And that's how the reduction in SG&A will come, headcount decrease. It's happening, but I would pay attention to the reals, to the expense itself. It's more relevant than the number of headcount, that's what I'm trying to say.
