Yes. Kunal, thanks for that. Expenses, yes, just to touch upon, you touched upon the ESOPs and RSUs, yes, that will continue. And that in the prior quarter, it was not a full quarter impact of the ESOPs and RSUs, because that went out later in October or November. So, part and then now you had a full quarter impact of that, but it's not a one-timer, that's an ongoing. That's one. Two, the branches, right? We opened 600-odd branches last quarter towards the end, that comes in, and then even this quarter we have opened up a little more than 600 branches. So that's also an ongoing impact that comes in. And the way you think about the cost is, which we have in the past said, as you build the retail or you build the retail deposit franchise and you start to get back into the higher proportion of the retail asset franchise, there will be upfront cost that comes, which is what you have seen, right? The cost-to-income for the full year at 40.4%, or currently 42%. If you go back in line, that's kind of -- in '19, for example, it was close to 40%, the cost-to-income was 40%. And we had mentioned that our cost-to-income will go past 40%, 41%, and a quarter or 2 can touch 42%, we'll operate at that level. And if we operate that level, there is an opportunity why -- what presents to us this opportunity is from the benign credit environment. So, if you look at the credit, 10 basis points of a better credit, when that opportunity is taken and invested in expenses, that is about 1.5% to cost-to-income. That's about 1.5%. And so, if you think about it, we do see that the credit cost benign conditions now and in some time to come. And so, we -- our goal is to get this maturity, both on the branches and the productivity curve up on the people that we have added 31,000 people over the year and 6,600 people in the quarter, to get them up the curve and be productive. And as things normalize, the revenues starts to come in, right, that's the ramp-up on the volumes that we're trying to do to get that in, so that it pays through the revenue and the credit as the maturity of the new cohorts come in and get to be -- the new cohorts get to mature state, credit cost normalizes to pre-COVID levels, not to the COVID levels to pre-COVID levels, so you get to a stable return on asset, right? You continue to operate in that 1.9% to 2.1% type of a range on return on asset, but we took this opportunity on the credit to invest in the expenses. So, that's how we will think about that.
