Okay. Two things. One is at the macro level. First is -- I'll take the NIM first. You saw the NIM for us over the last 12 months, if you see, operates in -- operated in a very narrow band, 3.4% to 3.5%. Last year, March quarter was 3.44%; now on a core basis, 3.46%; last quarter was 3.43%; and so on. So it's in a very narrow band plus/minus 5 basis points here and there. That's where the NIM has operated. And if you look at the components of the NIM, one is the cost of funds, which is one -- in one of our pages, where we published that, which is I think is on Page #15 or -- 15 I think it is in our deck. The cost of funds is also very stable at about 4.9%. And there are 2 things going on in the cost of funds to be stable there. One is the borrowing mix has come down during this time period. Whatever is on the page there, you see that the borrowing mix in the first of the time period, December '23, was 21%; and then from then on last March, it was 18% and now it is 14% borrowing mix. So that's one of the tailwind that contributed as a positive item to the cost of funds. Then there is a headwind in the cost of funds we have seen is the customer preference towards time deposit. If you see the rate of growth even in the recent time period, time deposit rate of growth, INR 2 trillion in a full year time period. In a quarter -- this quarter, recent quarter, about INR 0.8 trillion; time deposit rate of growth, 20% or so, right? So we have seen that. So the CASA ratio mix has not been favorable. It's an adverse variance there, right? But between all of these, the cost of funds, we kept it stable by selecting retail deposits and not pricing up on the nonretail deposits. And we'll come to the second aspect of what you asked. So the nonretail, we've been circumspect, even from -- I think it's going back to almost December '23, that time period itself, we saw that the pricing on the nonretail deposit was unacceptably high and competitive without consideration for the liquidity lendable value of those deposits. So we remain circumspect and then priced but try to manage it in a way that it's in a very narrow band there. Now come to the yield on assets, the other component of the NIM before we get to the conclusion of what you'd asked. So if you look at the yield on assets, they've also been pretty stable between 8.3%, 8.4%. That's the level at which we operated and that's how we manage that. Now yield on assets, if you see here, the retail will give more yield than the nonretail because then you'll have to pay through credit cost in some manner now or at some point in time. But we have had a balanced growth there to manage this yield in a very stable band there. And again, selection, we have seen over the last 12 months, 18 months, the corporate loans of the larger-ticket corporate loans and the larger-ticket SME loans have been very competitive, particularly coming from certain public sector institutions where the growth is an objective and not necessarily margin or returns. We have seen that pricing is very, very low on those. I mean the loan spreads have been very low compared to the bond spreads. That -- when the bond spreads moves up or down, the loan spreads is not moving. It's actually coming down, which is what we are seeing. Now we try to manage it through appropriate selection, both where -- quality is, of course, the first criteria for selection. Quality passes, it has to pass credit -- or pass the rate. And if it doesn't passes, we were happy to let go and not necessarily bulk up the balance sheet because we said we can reposition the balance sheet and grow the loans at any time. So that's how we manage that. Now coming to what's happened in the recent time period. 3, 4 basis points always moves at any time for various reasons. And so that's -- there's no one particular one we can say. Of course, there is a cash reserve ratio that changed sometime in December. So part of -- there was some impact -- positive impact last quarter and the balance of the positive impact in this quarter, call it, a couple of basis points. And then a few basis points moves up and down. There is no kind of a finesse. And similarly, when the NPA changes, lower agriculture in the March quarter. That also is a good kind of a margin benefit you get to some extent, but they're all within a narrow band. That -- now where does it go? I don't want to provide an outlook where this goes. But all I want to tell you is that I described to you this long to tell you how we think about margin and how we manage, which is policy rates change, so the loans that are linked to policy rates like the repo rate gets changed right away, so -- which is a headwind. And the faster the policy rate changes, it starts to factor in faster. The deposit side or the funding side rates take time to factor it in. So I would urge not to look at quarter-to-quarter because it's not something that could be managed at all because the policy can change tomorrow and then the deposit rate can change over time. So you have to look at it at least a year or longer than a year to see how stable and how we are managing that margin level, which is what on the page that you are seeing shows that Page 15 at that kind of a level stability how it gets managed. That's the first part. The second part is you talked about the cash and investment and the corporate sector balance sheet, how it gets deployed. Again, the first part, I tried to answer that certain categories of deposits have lower lendable value, and the market doesn't price appropriately for that lendable value because that's how it should be. Typically, those kind of segmented deposits should be lower than a retail because the retail is the highest value -- lendable value you can get. But these type of deposits are priced far higher than the retail deposits. So thereby only for large relationships and how -- where we could get certain other product mix aligned well, we patronize and participate. And there are certain other institutions, like affiliated institutions to large corporates, that we patronize and hold it. That's because we want to keep the wallet share on our lending. We are the largest working capital bank in the country, so we want to keep that wallet share growing in a reasonable manner. So we participate to some extent on these. Otherwise, we don't bid for these kind of deposits.
