Probably the primary concern, the main thing, that we had to deal with was that because this was a unique approach to purchasing the aircraft, we recognized that the normal rules would not necessarily apply. That's why what the audit was about was to determine whether the organizations applied due diligence, and we define due diligence in terms of the basic practices of good management.
What would have been helpful to us in conducting the audit would have been if the departments had recognized more fulsomely the uniqueness of this particular approach that they were using, and had agreed up front on what the different roles and responsibilities were going to be. But because those were not there, we had to do the audit on the basis of good management practices and due diligence.
