That is a larger question. Dumping is the behaviour of individual companies, so I think we need to distinguish between dumping and subsidization. I think on the subsidization side, where a government is providing assistance to a company, the company itself is not necessarily losing money on that. They can charge lower prices because the subsidies make up for that.
On the dumping side, there could be a number of reasons. Steel is a very capital-intensive product to make. Once you get a steel plant in place and it's running, it is perhaps in your economic interest to produce as much as you can with that investment, even if for some of it you're not selling at as high a price as you can.
I'd also point out that dumping is a comparison, fundamentally, between the price it's being sold at in the export market and the price it's being sold at in the producer's own domestic market. It's a comparison of those two things. It's a differential pricing type of situation, so there might be different reasons why companies pursue a strategy where they're selling things at a different price. Obviously if they're selling below cost for a lengthy period of time, that is not sustainable. I'm not sure that companies are in that situation, necessarily, but it's a fairly complex calculation that goes into whether dumping is occurring or not. It is possible that companies can sustain it over a longer term because of the other factors involved in their production.
