Certainly, Sumit. Yes, I'll jump in on that. So let's go back to last quarter's conference call, that point in time and it came up in another question, too, a step change in net interest margins of about 10 basis points as a result of the change in the Aeroplan portfolio. So this quarter was a part quarter, 5-ish weeks after a transfer of value. So that's 4 basis points this quarter. So our underlying operations are up 2 basis points on a quarter-over-quarter basis, the continuing operations, if you will. And then next quarter will be a full quarter post-transaction and that will drop through another, as Kevin said, 5 to 6 basis points, again, a step change in NIMs. So to your question, Sumit, which is what's the underlying direction here, we have been guiding to kind of stable net interest margins and I've continued to guide us through that outlook. A couple of factors, though, that obviously are in play. One is the FirstLine mortgages. So that does help in our retention level for the continuing around 50%. And the margins are about double what we are getting in the broker channel. Which, just a side comment, it looks like what we'll do is take that $48 billion in balances, keep half of it, but end up with more net earnings once that process is over. But nonetheless, as far as coming back to the question itself, the net interest margins, that lifts it. Offsetting that industry factor is interest rates, as you pointed out, haven't been coming out. So that's still, on a year-over-year basis, is a grind. Less than what it's been in the past, but still -- so hence, that's why we kind of guide to neutral. Interest rates decline, still a factor, offset by the advantage we have in the FirstLine. Other factors are: we are competing, in a way, to be sensible in pricing, both in the mortgages. We're not -- we're certainly not the first to move on price decreases, but we try to be sensible on the pricing on that front. And on credit cards, we are looking to grow. We talked about Aventura and Aeroplan. Gerry mentioned the Tim Hortons card, which shows all the signs of being a very powerful and a good card. And we've got another one in the pipeline that we're working on. So as that builds, our credit card business from this space, is it builds that, as you put -- pointed out, soon, it will also help the margins going forward.
