Well, every year is different. Things come up that you may not know in advance of that year but that you have to prepare for. Obviously last year, for example, we had the visit of President Obama, which led to additional expense.
As for what other kinds of events will happen during the course of this year, but that we don't know about yet, is a good question. But I think it's important that we prepare for that.
Is there anything else we need to add to that?
