Yes. As part of the framework we operate under, the legislation requires us to do re-evaluations of older pesticides on a cyclical basis. We have been looking at a body of older chemicals, older pesticides that have been registered long before this legislation was in place. As we went through those products, we ensured that they were up to modern scientific standards.
Originally, I think there was a group of about nearly 400 older chemicals that we went through. As we went through it, about 25% of those chemicals did not meet our modern scientific standards and were either withdrawn by the manufacturers or, for a percentage of them, some of the uses were dropped off those chemicals because they no longer met our safety standards, so the way they were used was modified or the labels were changed.
Certainly, from an older chemicals perspective, we go back and make sure they meet our modern standards. We take action to make sure that they don't stay on the market if they don't meet them.
