That is my understanding, but it reminds me a bit of the issue we had with some of the equipment to raise the bars and so forth and the bollards when they had to be replaced, and I thought it didn't seem that long since they were built and I was assured that the life expectancy of these was much shorter than I would have thought for this sort of equipment.
This is a different case because it's new technology that's required, but these are concerns that I certainly have front of mind as we have these discussions.
