I appreciate the responses, thank you.
So my take aways from these discussions are:
1) The current DFARS rule on tying performance based payments to cost incurred is in violation of the law (NDAA FY17),
2) We must wait for the FAR councils to provide guidance or update the regulation to incorporate the new rule on PBPs,
3) The KO does not have to go by what's in the law until it's incorporated into the regulations,
4) The FAR/DFARS clauses in my contract govern (in this case, the DFARS clause that includes the language tying PBPs to cost incurred is in my contract).
So based on the above, we can't bill milestones in full if the milestone amount exceeds the costs incurred for the milestone.
Do you guys concur this is the conclusion?
