I must confess I'm not an expert on the issue; I am aware of it.
My understanding was there had been some consultations around that change, and yes, I'm aware that there was some concern in the industry. I believe it wasn't necessarily done as a cost-saving measure but in the interests of efficiency. I understood there had been general consensus prior to moving to that, but certainly we can get back to you with more information. We don't have someone here today who is totally familiar with that file. Certainly we'll make every effort to get back to you with an answer.
