Hi, thank you for the opportunity. Just one question from my side. I wanted to understand -- so from what I understand, the copper pricing is generally passed on.it's passed on to the trade with a slight lag. In this period, in this quarter, we saw the prices of copper increase as well as decrease both of which would have been passed on to the trade with a lag. I just wanted to know what actually goes and impacts the margin in volatile times. This is not the volatility we saw in COVID, so the magnitude has been lowered but still the impact on margin seems to be a bit more than what we were expecting. Just need to understand from your perspective how should we see it going forward from this?
So now nothing is being paid. So these margins are after royalty payment?
