The short answer is that technology doesn't exist for alternatives to PFOS in the metal plating sector. There has been some penetration of some alternatives and some applications, but the reality is that this sector is quite diverse. There's quite a different number of metals involved and different applications, and the technology just isn't there yet to suppress the fumes as a result of the plating for the whole industry sector. Again, there are small penetrations in some areas, but across the board we're not there. We're working with the industry sector and we've given them a clear date of five years to develop the alternatives and get them on the marketplace.
