It's hard to say when exactly we started, because it depends on the program. Some programs started in 1997, so we looked back to 1997. It's easier to say that we closed the books in June 2006. Sometimes we were able to have updated information until 2006, sometimes 2005, sometimes 2004. Depending on the measures we looked at, we could have covered 2000, 2002.... Overall, I would say close to a ten-year period.
On October 5th, 2006. See this statement in context.
