FAR 19.503—Reserves.
Plain-English Summary
FAR 19.503 explains when and how contracting officers may use a "reserve" in a multiple-award procurement conducted under full and open competition to ensure small business participation. It covers the authority to reserve one or more contract awards for eligible small business concerns identified in FAR 19.000(a)(3), the market-research findings required before using a reserve, and the difference between a reserve and a total or partial set-aside. The section also addresses what a reserve can produce in practice: awards to one or more qualifying small businesses, or in a bundled multiple-award procurement, awards to small businesses using a Small Business Teaming Arrangement. It further clarifies that the specific socioeconomic or program eligibility rules in Part 19 still apply, and it distinguishes contract-level reserves from order-level set-asides by stating that the limitations on subcontracting and the nonmanufacturer rule do not apply to reserves at the contract level, but do apply to certain set-aside or direct-order actions under FAR 19.504(c)(1)(ii). In practice, this section gives contracting officers a flexible tool when a full small-business set-aside or partial set-aside is not workable, while still preserving small business opportunities in multiple-award contracting.
Key Rules
Reserve authority is discretionary
Contracting officers may, but are not required to, reserve one or more awards in a multiple-award procurement using full and open competition. The authority applies only when the procurement is being structured as a multiple-award acquisition and the officer decides a reserve is appropriate based on market research.
Market research must support reserve use
A reserve is appropriate only when market research shows that a total set-aside is not feasible and a partial set-aside is also not feasible. The contracting officer must have a reasonable basis for concluding that the small business market cannot support the requirement in the ways needed for a full or partial set-aside.
Total set-aside must be infeasible
The officer must determine there is no reasonable expectation of receiving competitive offers from at least two responsible small business concerns that can perform the entire requirement at fair market prices, with acceptable quality and delivery. This is the threshold for concluding that a total set-aside will not work.
Partial set-aside must also be infeasible
If a total set-aside is not feasible, the officer must also find that a partial set-aside is not feasible because the requirement cannot be divided into distinct portions, or because at least two responsible small business concerns cannot competitively perform any portion of the requirement. This prevents use of a reserve when a partial set-aside would still be workable.
Reserve outcomes are limited to eligible small businesses
A reserve results in one or more awards to one or more types of small business concerns identified in FAR 19.000(a)(3). For bundled requirements that will become multiple-award contracts, the reserve may also support awards to small businesses participating through a Small Business Teaming Arrangement.
Part 19 eligibility rules still apply
The specific program eligibility requirements in FAR Part 19 continue to govern the reserve. The reserve does not waive size status, socioeconomic status, or other eligibility conditions that apply to the particular small business program involved.
Contract-level reserve differs from order-level set-asides
The limitations on subcontracting and the nonmanufacturer rule do not apply to reserves at the contract level. However, those requirements do apply to orders that are set aside or issued directly to one small business concern under FAR 19.504(c)(1)(ii).
Responsibilities
Contracting Officer
Conduct market research, determine whether a total set-aside or partial set-aside is infeasible, and decide whether to reserve one or more awards in a multiple-award full and open procurement. The contracting officer must also ensure the solicitation and award structure comply with the applicable Part 19 eligibility rules and distinguish between contract-level reserves and order-level set-asides.
Small Business Concerns
Compete for reserved awards only if they meet the applicable eligibility requirements in FAR Part 19. If participating in a bundled multiple-award procurement through a Small Business Teaming Arrangement, they must satisfy the arrangement and program requirements applicable to the acquisition.
Agency
Support acquisition planning and market research so the contracting officer can make a defensible reserve decision. The agency must structure the procurement in a way that aligns with small business policy goals while still meeting the government’s needs.
Offerors/Teaming Participants
Understand that reserve status does not eliminate all small business program requirements and that eligibility must be established for the specific program involved. In bundled multiple-award acquisitions, teaming participants must ensure their arrangement fits the solicitation and regulatory framework.
Practical Implications
A reserve is a fallback tool, not a first choice: the contracting officer should use it only after market research shows that a total or partial set-aside will not work.
The biggest pitfall is weak market research. If the file does not clearly support why at least two responsible small businesses cannot compete for the whole requirement or a portion of it, the reserve decision may be vulnerable.
Contractors should not assume a reserve means all small business rules disappear. Part 19 eligibility still matters, and the exact program requirements depend on the type of small business concern involved.
Be careful to distinguish contract-level reserves from order-level set-asides. The subcontracting limitations and nonmanufacturer rule may not apply to the reserve itself, but they can apply to certain orders issued under the contract.
For bundled multiple-award procurements, the Small Business Teaming Arrangement option can expand participation, but only if the solicitation and the participants’ arrangement satisfy the applicable requirements.
Official Regulatory Text
(a) In accordance with section 1331 of the Small Business Jobs Act of 2010 ( 15 U.S.C. 644 (r)(3)) and 13 CFR 125.2 (e)(4), contracting officers may, at their discretion when conducting multiple-award procurements using full and open competition, reserve one or more contract awards for any of the small business concerns identified in 19.000 (a)(3), when market research indicates— (1) A total set-aside is not feasible because there is no reasonable expectation of receiving offers that are competitive in terms of fair market prices, quality, and delivery from at least two responsible small business concerns identified in 19.000 (a)(3), that can perform the entire requirement; and (2) A partial set-aside is not feasible because— (i) The contracting officer is unable to divide the requirement into distinct portions; or (ii) There is no reasonable expectation that at least two responsible small business concerns identified in 19.000 (a)(3) can perform any portion of the requirement competitively in terms of fair market price, quality, and delivery. (b) A reserve will result in one of the following: (1) One or more contract awards to any one or more types of small business concerns identified in 19.000 (a)(3). (2) In the case of a solicitation of a bundled requirement that will result in a multiple-award contract, an award to one or more small businesses with a Small Business Teaming Arrangement. (c) The specific program eligibility requirements identified in this part apply. (d) The limitations on subcontracting and the nonmanufacturer rule (see 19.505 ) do not apply to reserves at the contract level, but shall apply to orders that are set aside or issued directly to one small business concern under 19.504 (c)(1)(ii).
