The prime contractor has the obligation to attest to it. Okay.
The second thing is that we've heard several members of the committee questioning what value, if any, companies like Dalian and Coradix provide for the charges and the government money they receive. I wonder if I could ask you about this, because I would have thought that you might question spending a lot of money on these sorts of intermediaries, but I would have thought that they performed some valuable tasks that take time.
The question was, why don't you deal with subcontractors directly? Do they not do a fair bit of the administrative things that are required in order to get something done for the government? Is that not the value that they add?
