There have been a number of improvements over time, but we're not there yet. Again that speaks to dovetailing our regulatory regimes. Based on science we're at a point now where there's a lot of work-share that goes on, where we do have joint submissions. PMRA and the U.S. EPA will do work-share and they will parse out the work so that there isn't that duplication. There have been some changes made to crop groupings and zoning that have all been very positive.
The biggest areas we see the differences in now are things like worker exposure, the timeline to be able to go back into a field after you've applied a product, cancer risk assessment. We're getting to a point where we are reasonably close.
