I can give you a very detailed answer with my CFO sitting here or I can give you the big strategic picture.
The big strategic picture is that this is a 10-year program, as I outlined. It's in partnership with the airports. The airports own the infrastructure and they build the whole baggage system that moves the bag. What we do is provide the X-ray machines. The airports, though.... We established this plan way back in 2010 based on an expectation of what the airports schedule for those investments would be. As time passes, the schedule changes, so while we remain within the overall budget, we have to move money from one fiscal year to the other in order to remain aligned with the airports' plan. This $6 million isn't new money; it's essentially a realignment of existing money.
