I was just going to respond, Madam Chair, to that question, but I think I would turn to my colleagues for the very specific rules in that case.
As a general comment, in administering this program we have to recognize some of the complexities in the relationships and in the changes that happen. As you say, somebody could leave the country. Although we don't have statistics on how much we can get back there, I think it's fair to say that it doesn't increase our chances of recouping that money.
Similarly, in the situation of a breakup, it can often be the case that the two parties don't agree. That could be more complex for us to work our way through, but we do try to work our way through it.
