I don’t understand what you mean by contracts being held. Have the contracts been awarded to commercial entities but not fulfilled? Are there not deadlines for fulfillment, otherwise the contracts, and payment, are forfeit?
When the fedgov develops a repair contract, they won’t even put it up for bidding. It goes in a pile because that contract is a money-maker for whatever company bids on it. While it’s not being bid on - the fedgov puts a value on it pretty much at random. There are no rules to set the price.
So the contract will be worth, say “ten billion dollars”. Of course, when the bidding begins the value becomes real. But during that fiat value stage, it’s held as an asset.
