Which of the following contract types is described in the statement below? "This contract type provides no incentive for the contractor to control costs and hence is rarely utilized."

Cost Plus Fixed Fee (CPFF) reimburses costs plus a predetermined fixed fee that does not change with cost fluctuations, giving the contractor some motivation to control costs since their fee is capped.

Cost Plus Award Fee (CPAF) includes a base fee plus an award fee determined by the buyer's subjective evaluation of contractor performance, creating an incentive for the contractor to perform well and manage costs.

Cost Plus Incentive Fee (CPIF) shares cost overruns and savings between buyer and seller according to a pre-agreed formula, directly incentivizing the contractor to keep costs down.

In a CPPC contract, the contractor's fee is directly calculated as a percentage of the total costs incurred - the higher the costs, the larger the fee. This structure gives the contractor a financial incentive to increase costs rather than control them, making it the most unfavorable contract type for the buyer and the reason it is rarely used or even prohibited in many government contexts.
