As I said, in 2010 or 2009 we established very strict guidelines for travel over 1,000 kilometres. Other expenditures that are within the operational budget and operational expenses are reviewed very carefully before the budget is approved. We have an audit committee that goes over it line by line, and believe me, we've been clear in understanding the period of restraint from when it began and all the necessary cuts have been made. The structure has been thinned down, and we continue to examine all aspects of what we do to make sure it can't be delivered more efficiently.
Going back, at that time it did not require a formal authorization. Today it would. You know how I feel going forward.
