FAR 16.203-1—Description.
Plain-English Summary
FAR 16.203-1 explains what a fixed-price contract with economic price adjustment (EPA) is and how it works in practice. It covers the basic concept of upward and downward price revision when specified contingencies occur, and it identifies the three recognized EPA methods: adjustments based on established prices, adjustments based on actual labor or material costs experienced by the contractor, and adjustments based on identified cost indexes or standards for labor or material. The section also explains that this contract type can be combined with award-fee incentives and performance or delivery incentives, so long as the award fee or incentive is based solely on factors other than cost. Its purpose is to give contracting officers a way to manage price risk in volatile markets while preserving the fixed-price structure, and to tell contractors exactly what price-change mechanism will apply if the contract includes an EPA clause. In practice, this section matters because it affects how offerors price risk, how the government protects itself from market swings, and how contract terms must be written to avoid disputes over when and how the price may change.
Key Rules
EPA allows price revision
A fixed-price contract with economic price adjustment permits the stated contract price to be adjusted upward or downward if specified contingencies occur. The adjustment mechanism must be tied to the contract terms, not left open-ended.
Three EPA methods
The regulation recognizes three general types of economic price adjustment: based on established prices, based on actual labor or material costs experienced by the contractor, and based on identified cost indexes or standards. The contract must clearly identify which method applies.
Established-price adjustments
These adjustments track increases or decreases from an agreed-upon level in published or otherwise established prices for specific items or the contract end items. This method is used when market prices are objectively available and can be referenced in the contract.
Actual-cost adjustments
These adjustments are based on the contractor’s actual increases or decreases in specified labor or material costs during performance. The contract must define the covered costs and the basis for measuring the change.
Index-based adjustments
These adjustments use labor or material cost standards or indexes specifically identified in the contract. The index must be named in the contract so the parties know exactly what benchmark controls the adjustment.
Compatible with incentives
The contracting officer may use a fixed-price contract with EPA together with award-fee incentives and performance or delivery incentives, but only when the award fee or incentive is based solely on factors other than cost. The presence of these incentives does not change the contract type.
Responsibilities
Contracting Officer
Decide whether an EPA contract is appropriate for the acquisition, select the proper adjustment method, and clearly identify the contingency, pricing basis, or index in the contract. If using award-fee or performance/delivery incentives, ensure those incentives are based solely on non-cost factors and that the contract remains properly structured as fixed-price with economic price adjustment.
Contractor
Price the offer with the EPA mechanism in mind, understand which costs or indexes may trigger adjustments, and maintain records needed to support any claimed price revision. The contractor must perform under the contract terms and apply the specified adjustment method rather than seeking informal or unsupported price changes.
Agency
Support acquisition planning and market analysis so the contracting officer can determine whether price volatility justifies an EPA structure. The agency should ensure internal review and administration processes can handle the selected adjustment method and any associated incentive arrangements.
Practical Implications
EPA clauses help manage inflation and commodity volatility, but they must be drafted with precision; vague contingencies or undefined indexes are a common source of disputes.
Contractors should pay close attention to what costs are covered and what evidence is required, especially for actual-cost adjustments where documentation can be burdensome.
Using award-fee or performance incentives does not convert the contract into another type, but the incentive criteria must stay separate from cost-based adjustment triggers.
Contracting officers should confirm that the chosen EPA method matches the market condition being addressed: published prices, actual cost experience, or a reliable index.
Both sides should watch for double counting, where the same cost movement could affect both the EPA adjustment and an incentive measure if the contract is not carefully written.
Official Regulatory Text
(a) 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. Economic price adjustments are of three general types: (1) Adjustments based on established prices. These price adjustments are based on increases or decreases from an agreed-upon level in published or otherwise established prices of specific items or the contract end items. (2) Adjustments based on actual costs of labor or material . These price adjustments are based on increases or decreases in specified costs of labor or material that the contractor actually experiences during contract performance. (3) Adjustments based on cost indexes of labor or material . These price adjustments are based on increases or decreases in labor or material cost standards or indexes that are specifically identified in the contract. (b) The contracting officer may use a fixed-price contract with economic price adjustment in conjunction with an award-fee incentive (see 16.404 ) and performance or delivery incentives (see 16.402-2 and 16.402-3 ) when the award fee or incentive is based solely on factors other than cost. The contract type remains fixed-price with economic price adjustment when used with these incentives.
