Example of CAS covering part of a contract

Does anybody have an example of a contract that states that CAS applies to some, but not all, CLINs? I would expect a contract that contained a combination of pricing arrangements (FFP, cost-reimbursement, T&M) may be written this way. Do such contracts exist or are they an urban legend?

Don, I've never seen one. I wish I had! It would solve some problems for me....

I very much hope somebody gives you a positive reply.

I would think that if CAS applies to a portion of the contract and the contractor is otherwise subject to CAS then the "non-covered" portion might as well be covered as well as far as cost accounting is concerned. For example, we burden our commercial contracts the same way as our CAS-covered government contracts.
