Other Transaction (OT)
An Other Transaction (OT) is a legally binding agreement used by certain federal agencies that is not a procurement contract, grant, or cooperative agreement. OTs are designed to provide flexibility for research, prototype development, and innovation efforts, operating outside the Federal Acquisition Regulation (FAR) framework [citation:1][citation:8].
What Is an Other Transaction?
An Other Transaction (OT) is a legally binding agreement used by certain federal agencies that is not a procurement contract, grant, or cooperative agreement. OTs are designed to provide flexibility for research, prototype development, and innovation efforts, operating outside the Federal Acquisition Regulation (FAR) framework [citation:1][citation:8].
OTs were created to address the needs of agencies like the Department of Defense (DoD) to acquire research and development projects and prototypes in a more streamlined manner. They offer a flexible, strategic partnership between industry and the government to foster innovation and promote collaboration [citation:1].
Statutory Authority
OT authority is granted by statute rather than the FAR. Key authorities include:
10 U.S. Code § 4021 for research and development projects [citation:1]
10 U.S. Code § 4022 for prototype projects [citation:2][citation:3][citation:6]
Agency-specific OT guidance and policy memoranda
Key Characteristics
Legally binding but not governed by the Federal Acquisition Regulation (FAR) [citation:1][citation:8]
Primarily used for research and prototype projects
Offers flexible terms and negotiation structures
Encourages participation from nontraditional contractors [citation:1][citation:3]
Authorized by specific statutory authority
Nontraditional Defense Contractors
A key feature of OTs is their ability to attract nontraditional defense contractors—companies that have not recently performed under traditional cost-type government contracts subject to full Cost Accounting Standards (CAS) coverage.
As defined in 10 U.S.C. § 3014, a nontraditional defense contractor is "an entity that is not currently performing and has not performed, for at least the one-year period preceding the solicitation sources by the Department of Defense for the procurement or transaction, any contract or subcontract for the DoD that is subject to full coverage under the cost accounting standards prescribed pursuant to section 1502 of title 41" [citation:1][citation:3][citation:10].
OT vs. FAR-Based Contracts
FAR-Based Contracts: Highly regulated with strict terms and conditions, predictable but cumbersome, and can lead to steep compliance costs [citation:1].
Other Transactions (OTs): Flexible with fewer regulatory burdens, designed for speed and collaboration, but operate in a relatively undefined legal area with less precedent [citation:1][citation:5].
How It Works in Government Contracting
OTs are commonly used during early research, development, and prototyping phases. They may precede a follow-on production contract or transaction [citation:2][citation:6].
Where It Appears: OTs are used during early research, development, and prototyping phases, and may lead to follow-on production.
The Consortium Model: Many OTs operate through consortiums—legal entities whose members include both traditional and nontraditional defense contractors, academia, and government stakeholders. The consortium management firm (e.g., Advanced Technology International) facilitates agreements and payments [citation:3][citation:8]. Examples include the Maritime Sustainment Technology and Innovation Consortium (MSTIC) [citation:3].
Follow-On Production: Successful prototype OTs may transition into follow-on production contracts if statutory requirements are met. The "Prototype to Production Act" proposed in 2025 seeks to modify these provisions [citation:2][citation:6][citation:9].
Conditions for Use
For prototype projects under 10 U.S.C. 4022, the authority may be used only when:
At least one nontraditional defense contractor is participating to a significant extent in the prototype project [citation:3][citation:10]; or
At least one-third of the total cost of the prototype project is to be paid out of funds provided by non-Federal parties [citation:3][citation:10]; or
The Senior Procurement Executive determines in writing that exceptional circumstances justify innovative business arrangements that would not be feasible under a procurement contract [citation:3][citation:10].
Regulatory Framework
Although OTs are not subject to the FAR, they must comply with applicable fiscal laws, property laws, and other statutes not tied to the type of instrument used [citation:5][citation:10].
Key requirements that may still apply include:
Executive Orders and statutes related to discrimination, environmental protection, and labor standards
Fiscal law restrictions on obligations and expenditures
Intellectual property provisions, which are often negotiated on a case-by-case basis [citation:5][citation:8]
Why It Matters for Contractors
Business implications: OTs provide access to federal funding with fewer regulatory burdens, making them attractive to startups, small businesses, and nontraditional contractors [citation:1][citation:8].
Compliance impact: Contractors must understand unique negotiation terms, intellectual property provisions, and cost-sharing arrangements. While flexible, OTs still require careful attention to applicable laws [citation:5].
Strategic importance: OT participation can position a company for follow-on production opportunities and long-term relationships with government agencies [citation:1][citation:2].
Risk considerations: OTs operate in a relatively undefined legal area with less precedent than FAR-based contracts. Critical issues such as dispute jurisdiction are still being resolved by courts [citation:1]. Contractors should carefully review terms, especially intellectual property rights and dispute resolution clauses.
Common Misconceptions
OTs are informal agreements.
OTs are legally binding agreements with the federal government [citation:1].
OTs are unrestricted.
OTs are limited to specific statutory purposes and must comply with applicable laws [citation:5].
OTs eliminate oversight.
Agencies still apply internal controls and reporting requirements; OTs are subject to review by the Government Accountability Office [citation:5].
All terms are negotiable.
While more flexible than FAR contracts, OTs must still include certain provisions required by law or Executive Order [citation:5].
Frequently Asked Questions
Are OTs subject to the Federal Acquisition Regulation?
No. OTs operate outside the FAR framework, though other federal laws and fiscal regulations still apply [citation:1][citation:8][citation:10].
Can an OT lead to a production contract?
Yes. Successful prototype OTs may transition into follow-on production contracts if statutory requirements are met, including provisions in the original OT solicitation for follow-on production [citation:2][citation:6][citation:9].
Who qualifies as a nontraditional contractor?
An entity that has not performed a DoD contract subject to full Cost Accounting Standards (CAS) coverage for at least one year preceding the solicitation [citation:1][citation:3][citation:10].
Are OTs only for large defense contractors?
No. OTs are specifically intended to attract small businesses, startups, and innovative technology firms that might be deterred by traditional FAR-based contracting [citation:1][citation:8].
How are OT disputes resolved?
Dispute resolution mechanisms are negotiated in the OT agreement. Unlike FAR contracts, there is less established precedent, and jurisdictional issues are still being defined by courts [citation:1].

Follow-On Production: A subsequent contract or transaction to further develop, test, produce, deploy, operate, or sustain a successfully prototyped capability [citation:2][citation:6].
Cost Accounting Standards (CAS): Standards that define nontraditional contractor status; companies not subject to full CAS coverage may qualify as nontraditional [citation:1][citation:3].
Strategic Importance
Other Transactions have become an increasingly important tool for federal agencies to access innovation quickly and efficiently. From FY 2017 to FY 2022, OTA projects awarded increased from 496 to 4,391, and total monetary value grew from around $2 billion to over $10 billion [citation:1]. This growth reflects the value agencies place on the flexibility and speed that OTs provide.
For contractors, OTs offer a pathway to federal contracting with fewer regulatory burdens, making them particularly attractive to startups, small businesses, and companies with cutting-edge technologies. However, the flexibility of OTs comes with trade-offs—less established legal precedent, negotiated intellectual property provisions, and the need for careful attention to terms and conditions.
As proposed legislation like the "Prototype to Production Act" continues to refine OT authority, contractors should stay informed about evolving requirements and opportunities. Whether pursuing OTs directly or through consortiums, understanding this unique contracting mechanism is essential for companies seeking to participate in federal research, development, and prototyping efforts [citation:2].
