Yes and no, it depends. For the sake of this conversation lets say company X needs a peculiar state of the art lathe in order to make a landing gear for Fighter X. They can buy that lathe outright and recapture the cost as OH, but that OH rate is used on everthing the company bills for, military, commercial etc. So even though that machine cost $1M the Fighter X project is only going to pay $10k for the use of the machine by virtue of the OH rate. If the lathe is purchased for the project, and it's total $1M cost is built into the project estimate it belongs to the goverment when the job is done.I see. So typical gross profit margins on a given contract will be 3.97-4.11%, and that the upgrades for production facilities are indirectly worked into the contract?
How would they know? Easy. A bidder will include a schedule of values that details the costs for the project, and I mean details. Also when you start doing this kind of work, the government is going to have auditors at your location full time anyway.
As far as the plant goes, again that's pretty much up to the company to keep it state of the art, in fact that could very well be the competitive advantage they have over their rivals, offering a "best value" to the customer, or so it's said.
