We don't have the exact nature. I think Derek may have a little more detail.
I'll preface this by saying that sometimes the number of spikes in one year is simply a carry-forward from the previous year. So you have terminations. As I said, we have to give notice of termination and allow the individual who has given the notice to make representation. Sometimes it carries over several weeks or several months. Then one year may end up with a spike as a result of carry-overs.
Derek has some details on the nature of this.
