FPEPA: Fixed Price Economic Price Adjustment: These types of contracts are used for long term projects. Buyer bears the extra burden of Economic fluctuation which is a risk.
CR: Cost Reimbursable
CPF Cost plus Fee or CPPC “Cost plus Percent of Cost”: These types of contracts are illegal and not permissible for US Govt.

CPFF Cost plus fixed fee: Buyer reimburses all expenses to the seller and adds a fixed fee as a seller’s profit.
CPIF Cost plus Intensive fee: Buyer reimburses all expenses to the seller and adds an incentive for higher.
