Mr. Conor O'Kelly:

It is really, but we have made some assumptions which suggest a maximum period of five years and an average of three. That informs our guess as to how long it will take, but we do not know. I do not know whether the Department has a view on the matter. We are to manage the money and decided that was the basis on which we would start. An average life of three years is the way we have constructed it. If things change, we can adjust the policy.
