The Federal Acquisition Regulation Part 17 sets out six special contracting methods for situations where standard annual procurement will not do the job: multi-year contracting, contract options, leader company contracting, interagency acquisitions, management and operating contracts, and reverse auctions.1Acquisition.GOV. Federal Acquisition Regulation Part 17 – Special Contracting Methods Each method addresses a different mission need, and each carries its own approval requirements, ceilings, and documentation.
Multi-Year Contracting
A multi-year contract lets an agency buy up to five program years of a supply or service in a single award, even when the full funding is not yet available.2eCFR. 48 CFR 17.104 – General That is different from a multiple-year contract, which strings together a base year and options; in a multi-year contract, no separate option exercise is required for each subsequent year.3Acquisition.GOV. 48 CFR 17.103 – Definitions The contractor gets more certainty, and the government generally gets lower per-unit pricing.
For the Department of Defense, NASA, and the Coast Guard, the agency head may authorize a multi-year contract for supplies when the arrangement will yield significant savings over annual contracts, the quantity needed is expected to stay substantially unchanged, and the product design is stable with manageable technical risk.4Acquisition.GOV. FAR Subpart 17.1 – Multi-year Contracting
Cancellation Ceilings and Funding
If Congress does not appropriate funds for later years, the agency cancels those years. The cancellation ceiling is the maximum charge the contractor can collect when that happens, and it exists to protect contractors who invest in tooling, staffing, or materials on the strength of the multi-year commitment.3Acquisition.GOV. 48 CFR 17.103 – Definitions
Funding follows OMB Circular A-11. Obligated funds must cover potential cancellation and termination costs, and contracts for fixed assets should be either fully funded or funded in economically viable stages.2eCFR. 48 CFR 17.104 – General The contracting officer limits the government’s payment obligation in any given year to what has actually been appropriated, updating the contract each program year as funds become available.
Contract Options
An option gives the government the right, not the obligation, to buy additional supplies or services or to extend the term. It is the most common way agencies keep continuity with a performing contractor without running a fresh competition each year.
Including Options in a Solicitation
A contracting officer may include options when doing so serves the government’s interest. For sealed-bid procurements, the officer must make a written determination that the options are reasonably likely to be exercised before adding an option evaluation provision.5Acquisition.GOV. Federal Acquisition Regulation Subpart 17.2 – Options Options are usually not appropriate when market prices are likely to shift substantially, when the contractor would face undue risk, or when the quantities represent firm requirements rather than estimates.
Unless the agency approves a longer period, total contract duration including all option periods cannot exceed five years for services, and total option quantities cannot exceed a five-year supply requirement. Information technology contracts are exempt from the cap.6Acquisition.GOV. 48 CFR 17.204 – Contracts Other statutes, such as the Service Contract Labor Standards, may impose their own limits.
Exercising an Option
Exercising an option is not automatic. Before doing so, the contracting officer must confirm in writing that funds are available, that the requirement still exists, and that the option is the most advantageous method of meeting the need when price and other factors are weighed against alternatives such as a new competition.7Acquisition.GOV. FAR 17.207 – Exercise of Options The officer must also verify the contractor is not listed in the System for Award Management Exclusions, review past performance evaluations, and confirm that performance on the current contract has been satisfactory. Written notice must go out within the time specified in the contract.
Leader Company Contracting
Leader company contracting is reserved for cases where only one company has the production know-how the government needs and additional sources of supply must be built up. The agency designates that company as the “leader” and contracts with it to share technical assistance with one or more “follower” companies.8Acquisition.GOV. Subpart 17.4 – Leader Company Contracting
The stated goals include reducing delivery time, dispersing production geographically, making better use of scarce tooling, achieving production economies, and easing the transition from development to competitive production. It can also resolve proprietary data disputes with no cleaner solution. The FAR calls this an “extraordinary acquisition technique” and limits it to cases where no other source can meet the need without the leader’s help, with only the minimum necessary assistance provided. The government reserves the right to approve subcontracts between the leader and its followers.
Interagency Acquisitions
FAR Subpart 17.5 covers purchases one agency makes through another agency’s contract vehicle. It distinguishes direct acquisitions, in which the requesting agency places and administers the order itself, from assisted acquisitions, in which the servicing agency handles the procurement on the requester’s behalf.9Acquisition.GOV. FAR Subpart 17.5 – Interagency Acquisitions
Written Agreements for Assisted Acquisitions
Assisted acquisitions require more paperwork because the servicing agency acts as the contracting office. Before any solicitation is issued, both agencies must sign a written interagency agreement spelling out who handles acquisition planning, contract execution, and ongoing contract management. The requesting agency provides any unique terms, conditions, or agency-specific requirements to be incorporated into the contract.10Acquisition.GOV. 48 CFR 17.502-1 – General Each agency keeps the agreement and enough documentation to support a proper audit. Direct acquisitions require no such agreement, since the requesting agency runs the order itself.
Economy Act Determinations
When the legal authority for the interagency purchase is the Economy Act, the requesting agency prepares a formal Determination and Findings stating that the interagency route is in the government’s best interest and that the supplies or services cannot be obtained as conveniently or economically by contracting directly with a private source.11Acquisition.GOV. Federal Acquisition Regulation 17.502-2 – The Economy Act The D&F must also show that one of three circumstances applies: the servicing agency has an existing contract that fits, the servicing agency has expertise the requesting agency lacks, or the servicing agency is specifically authorized by law to buy on behalf of other agencies.
Ordering Procedures
The order itself can go on any form acceptable to both agencies, but it should include a description of the supplies or services, delivery requirements, a funds citation, a payment provision, and the acquisition authority relied upon.12Acquisition.GOV. FAR 17.503 – Ordering Procedures
DoD Acquisitions Through Non-Defense Agencies
When a non-defense agency conducts an acquisition on behalf of the Department of Defense above the simplified acquisition threshold, the head of that non-defense agency must certify in writing that the agency will comply with applicable DoD procurement requirements for the fiscal year. Compliance covers the FAR, DoD financial management regulations, the Defense Federal Acquisition Regulation Supplement, DoD class deviations, and related guidance. Certifications are due within 30 days of the start of each fiscal year.13eCFR. 48 CFR 17.703 – Policy
Management and Operating Contracts
Management and operating (M&O) contracts run government-owned research, development, production, or testing facilities. The Department of Energy uses them extensively for the national laboratories, and other agencies with the right statutory authority can use them as well.14Acquisition.GOV. FAR 48 CFR Subpart 17.6 – Management and Operating Contracts The work is closely tied to the agency’s core mission, long-term or continuing in nature, and requires special protections for the orderly transition of personnel and work if the contractor ever changes.
Only the head of the agency can authorize contracting officers to enter into or renew an M&O contract, and that authority cannot be delegated. Every M&O contract must display its authorization on its face.15Acquisition.GOV. 48 CFR 17.602 – Policy
The contracting officer must review each M&O contract at appropriate intervals and at least once every five years to determine whether meaningful improvement in performance or cost might be achieved.16Acquisition.GOV. 48 CFR 17.605 – Award, Renewal, and Extension
Reverse Auctions
FAR Subpart 17.8 governs reverse auctions, in which sellers compete by bidding prices downward. The technique fits when market research shows a competitive marketplace, multiple vendors can meet the requirement, and the specifications are clear enough to support iterative bidding with multiple price submissions.17Acquisition.GOV. Subpart 17.8 – Reverse Auctions
A reverse auction is only a pricing mechanism. Contracting officers still follow all applicable acquisition rules for the particular buy, whether simplified acquisition procedures, negotiated procurement under FAR Part 15, or ordering from existing contract vehicles. When a reverse auction service provider is used, the FAR requires that vendors be able to register for free, that all bid information be kept confidential, that bidders be able to see the lowest current price without learning who submitted it, and that all offer data be turned over to the government at the auction’s close. Providers cannot bid in their own auctions and cannot imply they can secure government contracts for participants.
