Bicker!
To answer your question seriously though, just telephone them. It's hardly commercially sensitive information. Although I have to say that they probably can't answer it because it depends very much on the client and the mission.
I once had £4,000 + worth of catering on board an aircaraft that operated MAN/LTN 2 pax needless to say hardly any of it was touched, but it had to be there (just in case).
