Yes, a good question. Think about it, there is lots of different reasons why those estimates move every quarter. But basically, the primary reason is the one utility that, if you recall, that purchased has been incompatible call [ph] with our solution. We don't know -- we hear they're going to ramp up back into better call [ph] during 2014, so that's the difference between ultimate. So if you look at what they'll make in 2014 versus 2015, that would be a big difference between what they produce, and then ultimately, what they can earn in 2015. There is also another -- there is a couple of smaller plants that we're going to be moving to higher production locations. But by the time we take them off the line where they are now, move them, put the new footings in, and we might not get the production in 2014, but we would by 2015. So that's illustrative of two reasons why there is a gap between being up 10% to 20% next year versus the ultimate number. As for the remaining plants that will go into locations, remember what our objective is there: get those up and running, and then we'll probably ratchet down our percentage ownership of all the plants, so we end up with a portfolio of about 30 plants that -- I'm just going to say this -- that maybe we own 30% to 40% of. So it's really much more of a portfolio of investments than it is individual one-off ones that are causing some of these swings. So I hope that we should be well through that by the end of 2014, and then what we'll do is, we'll be able to say, let's say, "We got 30 of them that are producing. If one goes offline for a week, it doesn't hurt us that much in the overall smoothness of the earnings."
Charles Gregory Peters - Raymond James & Associates, Inc., Research Division: Great. And then just another question on the 2 large deals that you've done. On a full year basis, how do you think about the impact to overall margins to the segment? I think, in some of the disclosure, it seemed that these were higher-margin businesses that might need a little investment. But still I'm just trying to think about how you think of impact of the total margin.
