One, there was no cover-up.
Two, as I just mentioned with respect to the reference to the TI that wasn't received in Canada, the first cases we had were the subject of a field technical report in October, but we couldn't replicate the condition. We didn't know what it was.
That material was provided to engineering for a review. The first case we had that we could replicate--in other words, we could confirm that something was happening--was in late November. I think we moved as diligently as we possibly could to identify those issues and move to recall.
