Well, we've called this out to the last two or three quarters. And quite frankly, I am tired of speaking to all those issues. We are making headway. We're making headway with our hot metal supplier, Alcoa. In the past, the rolling mill and the smelter were owned by the same person. And when you have two separate owners, there are expectations on performance that perhaps weren't there in the past. So, we've had a lot of dialogue and a lot of focus on actions to improve that performance from the smelter to the operations, so that we get timely delivery of materials that don't negatively impact the efficiency of the operations. That's truly what we've done there. So, we've taken some significant actions in the first quarter. We expect to see some improved results from that, beginning in the second quarter going forward. With regards to our issue with the supply of mag, we've been very frustrated in this area. We're now in our seventh month where we were dealt with our major supplier for force majeure to the point we filed a complaint last week in the federal court in New York. The issues around the US Mag and their force majeure, there are three issues we have. One is whether or not US Mag was entitled to declare force majeure. The other was a failure to maintain a safety stock according to our contractual agreements. And then finally, US Mag's conduct since declaring force majeure has been very frustrating for us for the lack of communication and follow through on performance. And so, we're going to take those additional measures. Now, I have spoken in the past about actions that we have taken to minimize those, and those are being put into effect. Regardless of our outcome and the position with US Mag, a few of the things that we have done in that area, we have diversified our supply base. That's taken a little bit of time, given the global scenarios that are in place today, but we have diversified that supply position and we think that'll improve over time. And the other steps that we've taken, Emily, have been going back to our customers and changing out the timing of which we have ability to recoup these costs. And I would remind everyone, we do have provisions in our contracts that will allow us to recoup these higher costs, and we are doing so. But that has an impact later. Right now, we're dealing with those costs at hand. So I'm very pleased with the actions we've taken to reduce the impact on a quarterly basis of those costs. However, these costs are going to continue to be focused, and we're going to ramp up our performance, our actions there to finalize where we are here and move forward.
