It's difficult to tell by the year. We talked about some departmental reviews and how 68% were favourable. The issue we have is that we don't know from year to year which years they came from: they might be favourables and they came back. In 2011-2012, about 2,200 came back. Now, whether those were from the previous year or from years before, I don't know. I don't have that stat.
On October 1st, 2012. See this statement in context.
