This was never a subcontract. Since it's Fairview (the enrollments take place at UMMC), we just need to pay them for nurse time. We had set up a CPS, but when we finally received the invoice, it shows the salary/fringe and then an IDC charge. I've never seen IDC on a CPS before, so I wanted to make sure it was okay to pay overhead via a contract for professional services rather than through a subcontract. Does that make sense?
On a side note, this is a fixed price contract that's passed down many layers, but the prime source is NIH.
