I want to be more specific than that. The seven upgrades, the situation we are in now goes right back to 1993, so that is the reason the commissioner mentioned that there would be root cause investigation, and that is part of what we need to understand. It is part of that root cause investigation. It would be premature for me at this point to try to predict its outcome. However, clearly something occurred between 1993 and 2005 within the organization's understanding of what the scope of those upgrades were.
In 2005, we signed off saying that those upgrades were complete, and we did that, to the best of our knowledge, in the belief that they were.
At that time there were also communications back and forth that indicated this particular work, which was seen by the organization to be not part of the scope of the upgrades but enhancements, was also recognized and openly identified as not being done. That is the documentation I referred to earlier.
