There are several flavors of Cost Reimbursable (CR) contracts, the two most common at Georgia Tech are the pure Cost Reimbursement and Cost Plus Fixed Fee (CPFF). Including cost sharing in a contract or proposal is also a form of a cost reimbursable contract. The CR and CPFF contract is the preferred contract for the Institute to receive (without cost sharing), as it limits risk on research endeavors that may not have a clearly defined SOW. Under the CPFF, in addition to reimbursing the Institute for costs related to the work, the sponsor will also provide the Institute with a fee.
