With regard to determinations, there is a process by which, as you know, the agency undertakes to determine the degree of control that is applied in any specific complaint that has been filed with the agency. Typically, situations of control can pertain to operational issues that the airline may face with respect to their network, and where it's determined that they did have a degree of control over that, it is determined to be within their control.
I can turn to my colleague Mr. Stacey for some more specifics on that control issue, which was also addressed in the most recent regulations that came into force on September 8.
