Sure. Well, I guess I would just preface my comments by saying everything we do is about oil and chemicals. I mean, we're -- all of the environmental work that we do, oil spill cleanup work, chemical work, everything we do is derived around oil and other chemical waste. We have had to manage that commodity through our fuel surcharges on our transportation side of our business, our energy costs and running our incinerators, so forth and so on. So I think we just look at oil, and certainly the oil and gas business is something that we're very familiar with and know how to deal with it. I think that when you think about the Safety-Kleen lube oil business, that business certainly is a commodity business. But we have, we believe, a significant cost advantage in that we can control the cost of our feed product by what we pay or what we charge customers for our feed, for our waste oil. And so as much as we are dependent on the majors on pricing for base Group 2 oil, we have a lot of control in our pricing environment for both the collection side as well as adding more value on the blended side. And so you'll see us, over the coming quarters here and in the future, focus more on that less volatile area on base lube oil and focus more on that blended area. I think in regard to our exposure in general, for example, in the gas area, natural gas area, we have enough assets and equipment, around about 150 drill rigs. And considering there's over 2,000 drill rigs out there, we don't think we're overly exposed there. We just have got ourselves -- or had got ourselves where Peak had been, too concentrated on a limited group of customers. And so we've added a lot of sales folks. We've expanded our relationships with more accounts. We've tried to provide a more environmental-friendly bundled service to the drilling rigs, so that we could really differentiate ourselves significantly from simply just a rental company. And that particularly is focused on handling the waste side of the business, as well as the processing of the waste on the drill sites. So I guess, Hamzah, it's a pretty long-winded answer, but we're very capable of managing our way through this -- through the environment that we operate in here.
Hamzah Mazari - Crédit Suisse AG, Research Division: That's helpful. I appreciate that. And just to follow up, you highlighted 4 different business lines. I know you're going to come up with your new segmentation at Q1. What are your thoughts on -- do you need a COO position given the company is now over $2 billion? You have sort of all these different businesses, but yet you want to be sort of a one-stop environmental shop. How should people think about that role and the need for that role as you've grown over the years?
