The FAR material cost principle states at 31.205-26 (e)
"Allowance for all materials, supplies, and services that are sold or transferred between any divisions, subdivisions, subsidiaries, or affiliates of the contractor under a common control shall be on the basis of cost incurred in accordance with this subpart."
Hypothetical situation: Let's assume that there is work being performed by a sister unit for your company (separate CAS Segment), who is an affiliate under common control. The affiliate does not qualify to be able to transfer costs at price. Let's say for financial measurement purposes, you contracted for the work to be done by this affiliiate on a FFP basis. Your prime contract is CPFF, so the prime contract has the Allowable Cost & Payment clause. Therefore, you have to submit and certify final indirect rates. Let's say the affiliate's cost is part of an allocation base for an indirect rate of yours.
If the affiliate otherwise has no requirement to submit final indirect rates (no flexibly priced business), would they have to operate (for your sake) as if they were covered by the Allowable Cost & Payment clause (even though this is a FFP arrangement) and adjust their billings or memo entry their costs to you on an allowable actual costs incurred basis because of the fact that you have a CPFF contract and the above stated cost principle is in effect in your prime contract?
Would you include their actual costs incurred (both allowable & unallowable) in the allocation base for the indirect rate as mentioned above, or their FFP billings to you?
Thanks for your help.
