I will take that. That's a difficult question.
What was commonly referred to as the backlog occurred at a time in the pesticide regulatory experience when a submission was received by the government, and because of various reasons, resources being one, it was not a complete package and they couldn't finish their evaluation, so it sat.
One of the things the PMRA did in the late 1990s and into 2000 was take those submissions and find out if they had enough information to make decisions on the products. If they did, they made the decisions; if they didn't, they were taken out of the system.
So the backlog was dealt with in two ways. If they had enough information they went ahead and registered the product; if they didn't they took it out of the system.
