Yes, Steve, this is Kevin. Let me walk through some of that detail. So as we laid out in the first quarter, we saw an $839 million mark-to-market loss from an income statement that impacted refining M&S and renewables and the specific amounts by segment were detailed in the press release. . This is broadly consistent with what we put out in the 8-K. We said approximately $900 million. At that point, that was our best estimate at that point in time. And so I think it's important to make it clear that these are mark-to-market impacts on paper hedges that we have in place to offset physical purchases those purchases are mark-to-market at the end of each month, but the physical inventory is not. And so there's a net impact through the income statement. I do think it's important to emphasize that we do this to protect economic value. There is -- this is a risk mitigation tool. We've been doing this for some time. It's a standard practice. And in the normal course, the impacts of these mark-to-market transactions are just not that significant, not that material. But as Mark mentioned in his comments, we saw unprecedented volatility across the commodity markets in which we participate that course this, we'll see as a sort of outsized impact. as you look ahead in terms of what you can expect on a go-forward basis, it's very much a function of where the commodity prices move from end of March, I think through, say, the end of the year. And if we were to use the forward curve as of end of day yesterday, we'd recover by the end of the year, about $500 million of that $893 million. And it's a commodity-by-commodity calculation on a quarter-by-quarter basis. So based on the forward curve, if that were to play out as reality, that's what you see come back in that context. From a cash standpoint, we have -- at the end of the quarter, we had a total of $3.2 billion out on margin associated with all of this activity. That differs from the income statement effect because there are other barrels being marked where we actually do a corresponding impact to reflect the physical gain. And so you have more paper activity than is subject to the income statement related mark-to-market. That cash impact will come back -- 2 ways it comes back. One, directly in falling prices, you'll see the reverse effect. But in normal course, because this is a continual process as volatility subsides, we effectively consume this cash through a normal purchasing activity. So just to put some context around that, $3.2 billion out on margin at the end of March, at the end of yesterday, it was $2.1 billion, even though the absolute price levels are pretty similar to where they were at the end of the first quarter. And so we'll see that come down as we work our way through the year. And then as we get into -- what does this mean in terms of capital allocation, debt reduction, share buybacks, big picture. And I covered it in the earlier comments and the slide that we put in the presentation on debt targets, we think we will be able to utilize between working capital benefits and the remainder of the year, operating cash flow and as the market stabilize, we don't need to carry that much cash, which is what we showed at the end of the quarter and still do. But we can draw down that cash, get debt down to about $19 billion at the end of this year and then down to our target $17 billion next year, all while still returning 50% of our operating cash flow back through dividends and buybacks and quite frankly, we used Street estimates for cash generation in that calculation, but I feel pretty optimistic that there's upside there as well and we'll hold true to that. So 50% back to shareholders and the other excess will just accelerate debt reduction.
