Great replies, thank you.
The contract will not be funded entirely with current fiscal year appropriations.
I'm comfortable with that concept, though I'm not convinced that it's the only option here. The DoD FMR appears to me to offer requirements for the "recording" of obligations, which is different from the act of incurring an obligation (incurring a liability). For example, FMR Vol. 3, Ch. 8, paragraph 080304 states, "The office that generates an obligating document, in the form of a contract, order, or modification, must provide official evidence of the obligating documents...to the office responsible for recording the obligation."
DoD components must also record obligations in situations that don't involve contract actions, such as described in paragraph 081305: "As a general rule, the amount of the liability expected to result from pending litigation must be recorded as an obligation in cases where the government definitely is liable for the payment of the money from available appropriations...".
In short, I'm not sure the FMR answers the question.
