So we looked at situations, for example avian influenza, which we've had success in eradicating. If we hadn't been able to, the costs of managing that disease would have been pretty significant for the agency.
We recognize that the current way the legislation was drafted, we had no way of moving to a management approach in those situations. That's why it's here. It's part of that, recognizing the change in science.
