2-18.5 Fixed-Price Contract with Economic Price Adjustment

A fixed-price contract with economic price adjustment provides for upward and downward revision of the stated contract price upon the occurrence of specified contingencies. This type of contract establishes a basis for measuring fluctuations so that price adjustments are limited to contingencies beyond the supplier’s control and reflect actual market fluctuations. Upward adjustments are limited by establishing a reasonable ceiling, and provisions are included for downward adjustments when prices or rates fall below base levels established in the contract.

There are two types of economic price adjustments:

• Adjustments based on ACs of labor or materials — price adjustments based on actual increases or decreases in the costs of specified labor or materials during performance.
• Adjustments based on cost indexes of labor or materials — price adjustments based on increases or decreases in labor or material cost standards or indexes specifically identified in the contract.

Fixed-price contracts with economic price adjustment are appropriate when there is serious doubt about the stability of market or labor conditions during an extended period of performance and when contingencies that would otherwise be included in a FFP contract are identifiable and can be covered separately in the contract. Their usefulness is limited by the difficulties of administering them.

Fixed-price contracts providing for an economic price adjustment based on ACs of labor or materials must include Clause 2-28: Economic Price Adjustment — Labor and Materials, and fixed-price contracts providing for an economic price adjustment based on cost indexes of labor or materials must include Clause 2-29: Economic Price Adjustment (Index Method).
