I spoke earlier about section 241 of the Income Tax Act. Without referring to any specifics of what may have happened or not in the KPMG litigation, I can say that anything that would have been sent in that context would also be subject to settlement privilege, and so I believe that your question is an effort to determine whether or not this specific letter was sent in that specific case, and Ms. Henderson isn't in a position to answer that question.
