Yeah. I'd say, remember that when we look at the $2.1 billion to $2.3 billion in EBITDA, all we're really changing for the market impacts of the currencies, and then alumina and aluminum prices. So we continue to hold to the $50 million net performance target. Within that, there is a higher increase in caustic prices, and we expected, but we're planning on offsetting that with some of the overhead moves that we've made as an example. So we hold to the $50 million, and reflecting what's happening in the external environment. So since the end of the fourth quarter when we reported fourth quarter earnings, what we've seen is exactly what you've said, aluminum prices have increased, alumina prices have come off to a certain extent, and the Aussie dollar has also strengthened. So the mix of those things mean that our guidance essentially is unchanged, even though the mix is coming from different segments. And so, like Roy said, just versus prior guidance, alumina was up $105, so we went from $1,795 to $1,900. Alumina, I believe we're at $335, and we've taken it down to $305. There are loads of things that change within other factors, for instance, higher raw material costs, which will make that $50 million challenge that we've laid out for ourselves harder to achieve. But at this point, we've committed to achieve that, and maintain the $2.1 billion to $2.3 billion EBITDA level.
