What about the following DFARS section. Does anyone think it is referring to annual appropriations as well:
232.703-3 Contracts crossing fiscal years.
(b) The contracting officer may enter into a contract, exercise an option, or place an order under a contract for severable services for a period that begins in one fiscal year and ends in the next fiscal year if the period of the contract awarded, option exercised, or order placed does not exceed 1 year (10 U.S.C. 2410a).
I interpret this to be for all types of funding not just O&M.
Also, since the bona need for a service is when the service is performed, how is is accurate to say that it doesn't matter when the service performed? This would clearly be a bona fife need issue.
