I can say that there have been some discussions on some level, certainly before the Carbon Tax became law and mostly with regard to the structure of the Carbon Tax regime itself, not necessarily with the implementation of the program or of the draft guidelines, so I'm not sure that the discussions that were had are necessarily going to the substance of the matter that is at issue presently. If there have been any further discussions more recently, I would certainly endeavour to inquire about that, but to date my information is that the discussions were prior to the implementation.
