Six Funding Signals Defense Contractors Misread, and What Each One Means

Chris A. Grable · October 4, 2026

Contractors spend a great deal of energy guessing why a government customer is slow. In most cases the answer sits in three statutes: the Purpose Statute (31 U.S.C. 1301), the Bona Fide Need Rule (31 U.S.C. 1502) and the Antideficiency Act (31 U.S.C. 1341 and 1517). Below are six signals industry routinely misreads, what each one usually means, and what UDC recommends doing about it.

1. "The funding is there" and "the funds are not certified" are both true

A program office can move money two ways. It can contract directly through its Systems Command contracts office for a prime or production award, or it can send a reimbursable order to a laboratory or warfare center, which then buys support through its own contracts office. In Naval Aviation, for example, a PMA may award a production contract through NAVAIR Contracts while tasking NAWCAD for developmental engineering.

A warfare center engineer who sees the program office's intent to place an order will say funding is available. A Systems Command contracting officer who has no certified funds for a direct action will say it is not. Each is describing a different path. Knowing which path your work travels tells you whose answer to believe.

2. An award slides right after a confident customer conversation

Money descends from Congress through Treasury account symbols, OMB apportionment (usually by quarter), allocation to the Military Departments, allotment to program offices and, last, certification for the specific action. A delay at any level reads to industry as "waiting for funds." A contracting officer may not obligate in anticipation of future availability, even when higher headquarters has signaled that apportionment is coming, and obligating before an appropriation is available, or beyond the amount available, can violate the Antideficiency Act.

UDC recommends treating a customer's confidence as intent, not authority, and not starting work without a funded contract action.

3. A modification stalls for weeks in review

The usual cause is a line item that mixes purposes. A single contract line that combines "develop new software capability" with "install and maintain the production baseline" may need RDT&E for one part and O&M for the other. DFARS 204.7103-1 generally calls for one accounting classification citation per line item and allows multiple citations only in specified cases.

The language often starts with industry. Words from white papers, proposals and briefings find their way, sometimes verbatim, into purchase requests and budget justifications, and a phrase such as "develop and install" can leave the comptroller unable to tell which work needs which funds. Words do not decide the appropriation; the purpose and substance of the work do. Precise descriptions let the comptroller certify the right money quickly.

4. September brings a rush, and some of it gets unwound

One-year O&M must serve a need that arises in the year it is available. A one-year service renewal executed in September with performance entirely in the next fiscal year belongs to the next fiscal year, no matter how early the paperwork started. For annual funds, 10 U.S.C. 3133 allows a severable-service contract to begin in one fiscal year and run into the next if its period, excluding options, is not more than one year. Non-severable work, such as a single test campaign or a one-time certification package, is generally fully funded at award and can then continue across the fiscal-year line.

UDC recommends confirming severability and the period of performance before the fourth quarter, not during it.

5. New work stops under a continuing resolution while old work continues

A continuing resolution is itself an appropriation, and its terms govern. The FY2027 resolution (Public Law 119-103, Division A) carries FY2026 defense authority forward but bars new production of items not funded for production in FY2026 or earlier, production rates above those sustained with FY2026 funds, and projects or activities for which funds or authority were not available in FY2026. It runs to the earlier of its enactment triggers or December 11, 2026.

Working capital fund activities add a second layer. A warfare center under the Navy Working Capital Fund can often keep working on orders already funded, but it cannot start new work until a program office places a funded order. The same contractor can see one task proceed and another freeze for reasons that have nothing to do with performance.

6. A change to an old contract needs new money

When an appropriation's period of availability ends, the account stays open for five years to record, adjust and liquidate obligations properly chargeable to it, then closes and its balances are canceled. A change that reflects the government's antecedent liability under the original contract may be charged to the expired account. A new or discretionary requirement must use funds current when the need arises. Contract changes charged to an expired account face two cumulative tests: once change obligations for a program, project or activity in a fiscal year would exceed $4 million, the agency head or a delegate must approve, and once total obligations from that appropriation for the program, project or activity in the fiscal year would exceed $25 million, the designated congressional committees must receive written notice and wait 30 days. After closure, only a limited avenue under 31 U.S.C. 1553(b) remains.

UDC recommends disciplined closeout and timely invoicing, so that late bills never meet a closed account.

The common thread

An award authority tells the government how it may buy. The appropriation sets the object of the spending and the window for it. A company that can name the color of money alongside the award path it recommends, and say whether that money is in the budget for the year the award must happen, gives its customer an answer rather than another question.
