Chair, we had concerns over the revenue numbers in two aspects. One was that the estimates were actually underestimating the revenue. When we would go and look at actual assessments and collections later, we would find they were higher. There have been a number of modifications that have been made in the last year, but quite frankly, only time will tell—when we actually get the assessments—how much closer that assessment is.
I would say, though, from year to year the difference, sort of, in the opening and closing balances was never really a lot different, so the revenues within the year were fairly close. It's when we compared it to the assessments; there was always this difference that seemed to be going on. So we are hopeful that some of the adjustments that have been made in the current year will make it better.
The other area where we had expressed some concerns in the past was the methodology for determining the allowance for doubtful accounts on the taxes receivable. Again, there have been a number of improvements made this year. You can understand that with the recession, we were quite concerned that maybe the methodology, because it's based on past experience, may not reflect all of the potential losses. We went in and looked actually at specific sectors and did much more rigorous testing and are comfortable with the allowance now. We have indicated, though, to the revenue agency that we think it important that they continue to track this through the recession to see if the methodology in the model that has been developed will stand up going forward.
