When the monthly reporting was first being discussed, those same concerns—if I recall correctly—were actually discussed. Actually, it wasn't just confidential, it was security issues, which is why, when one looks at a monthly report, it doesn't have the particulars of the meeting. It would simply indicate “defence” or “finance”. The details are filed in the initial registration. The details are not in the monthly communication reports.
