I think, Bob, you're absolutely right. As I said in my call, we are increasing these on anticipation of coming price hikes. And we, like most producers, have contracts that will lock in ore prices for some period of time or we'll allow them only to increase by certain percentage. And you're right, as those contracts are renewed, I would imagine as we look at the trend of the negotiations that are taking place, those safeguards that we've seen in the past will most likely be coming off. Somewhat similar to a lot of our TiO2 pricing where you used to see 90-, 120-day sort of protection terms in the market. Those are becoming much tighter as well in the industry. It continues to tighten up. As you look at the overall ore supply in our industry, I haven't much concern around the supply of ore at the present capacity, the present utilization rate, but I do have some concerns as I look out over the next three to four years. If you think that this industry is growing at 3% or 4% and if you were to see some sort of a return in housing and automotive in North America, particularly housing to perhaps 1 million units, I don't want to talk like an alarmist here, but I do think that TiO2 and the supply of ore into TiO2, it used to just be a given that if you build the TiO2 capacity that the ore will always be there. And I'm not saying that the ore will not be there, I'm just saying that it may not be as plentiful as we've seen it in years past. And that may even be a limiting factor in the coming years on new grassroots expansion that come into this industry. As we look at our own ore situation for this next year, we're forecasting an increase of about 20% on ore prices. And I would just give you a cautionary note there, Bob, that when we talk about that 20% in ore prices, we're also seeing acidic prices increasing, coke prices. Energy prices continued to be strong in Europe and Asia. Caustic prices are going up. So it's not just ore but a lot of the raw material in TiO2 is going up as well now. I had a call from an analyst or two this last quarter saying that I sounded a little pessimistic about TiO2. I remain very bullish on TiO2, and I think it's going to be a great market for some years to come. But my only point in saying that last quarter and reiterating it this quarter is that, yes, we do have pricing momentum in this industry. We've also got raw material pressures in this industry as well, and it's yet to be seen just how much of that will counter how much, one, the raw materials have countered the market pricing.
