Okay. Good. See, if you look at the corporate bond book, it's not about fee book. It is about the corporate bond and the pass-through certificates, which are -- which are predominantly PSL driven or the qualified pass-through certificates, right, which are there. If you look at the rate, the base rate that determines the valuation of the bonds and PTCs are published by the FIMMDA various association that publishes the rate. The base rate is this technical -- the 6-month rate is up 77 basis points in the quarter, 1 year 67 basis points, 2 year, 42 basis points and so on. So that's the kind of the front-end part of the curve where the rates are up, the long-end part of the curve, if you look at the 10-year rates are down 9 basis points quarter-on-quarter, right? But these bonds and PTCs that we have, they are more on the front-end side, right? There are more. So if you look at the dispersion of the bond book, it's like a pretty good normal distribution around that 2-year type of range of bucket. That's where the normal distribution is there. That's one element. The G-Sec curve on the front end of the curve, that is one of the elements of that goes into valuation. So as a rate spike, you'll see the value coming down because, as you know, these are not economic link to market. The second aspect of it in the valuation is also the spread on spreads, right? And part of the evaluation process, the bond split has come down, right, which is -- you would imagine the bond spreads are down to some extent. And if you see the bond spreads, I think in the front end, also the bond is of down. If you see, for example, the NBFC AA spreads in the 6 months is down 6 basis points and 1 year down 21 basis points and 2 years down 11 basis points, right? It is down. Similarly, cost of AAA 1 year is 9 basis points down 2 years, 11 basis points down. So the bond price is another element of the valuation, they are also down. However, as you know, in the valuation, the bond spreads have slowed, right? They have flowed at 50 basis points. So until the bond spreads growth at that level and then starts to improve up or down, it is inconsequential on that front. So it is not driven by the G-Sec. And in this case, the position the portfolio is towards a normal distribution around that 2-year 1.5 2-year math. And so it depends on the rate that is changed in the contract.
