Yes. Gordon, as it relates to gross margin, I think one of the things we highlighted was even if we had relatively low revenues, but yet we had a very high margin. Again, that's primarily due to the, what we call, the deferred revenue. That is our deferred profit that sits on our books, that when we get customer acceptances, we then recognize that. That's usually at a very high profit margin. And we had, as it related to regular type of revenue shipments, its proportion was greater and, therefore, had a greater impact at the margin. Unfortunately, this business can be lumpy from quarter-to-quarter and that is what happens. So looking forward from a margin standpoint, we think, generally, we should see some relatively improved margins as the volume picks up. That's just -- and we saw that back in 2011 -- '10 or '11, when margins -- when volume improves, so did margins. As we're down at these lower levels, though, we are highly impacted by the revenue mix, where there's previously deferred revenue. Or when we do, do shipments, we are going to be deferring some revenues. So giving a little bit color going in 2014, Nexolon obviously is going to help. But as you can see from the backlog, there's more orders that need to come in, in order for it to be a better year and show improvements. But as in our commentary that we gave, our expectations are that we'll start to see that, especially in the second half of 2014.
