Examples
Worked examples
- Is an instance
A university issues a purchase order against a federal grant for a piece of lab equipment. The moment the PO is issued, the full order amount is obligated. It remains an unliquidated obligation on the university's books until the vendor delivers, is invoiced, and is actually paid (or, under accrual accounting, until the expenditure is recorded) -- at which point it converts from a ULO into a recorded expenditure.
- Is an instance
A prime recipient executes a subaward agreement committing $75,000 to a subrecipient for the remaining months of a project period. That committed $75,000 is a financial obligation on the prime's award as soon as the subaward is signed. It stays classified as unliquidated as the subrecipient does the work and submits invoices, and only liquidates in increments as the prime actually pays each invoice.
Counter-examples
Looks similar, but isn't
- Not an instance
A recipient has $40,000 in federal funds still authorized under an award, but has not yet issued any purchase order, signed any contract, or executed any subaward against that amount. This is an unobligated balance, not a ULO -- no obligating action has occurred yet, so nothing has been legally committed. It only becomes a ULO at the moment an order, contract, or subaward is actually put in place against it.
Editorial commentary
Unliquidated obligations (ULOs) are amounts a federal award recipient has legally obligated — through an executed contract, purchase order, or similar commitment — but has not yet actually paid out as of a given reporting date. An obligation becomes “liquidated” once the recipient pays the vendor, employee, or subrecipient; until then, it sits on the books as unliquidated.
Where ULOs show up
Recipients report unliquidated obligations on the Federal Financial Report (SF-425), which separates total federal obligations into the amount already disbursed (outlays) and the amount still obligated but unpaid (unliquidated obligations). This distinction lets a federal awarding agency see not just how much money has physically gone out the door, but how much additional spending is already legally committed and pending.
Why the distinction matters at closeout
At award closeout, a recipient is generally required to liquidate all obligations and submit final financial reports within a set window after the period of performance ends (120 calendar days under 2 CFR 200.344 for most federal awards). A large unliquidated-obligations balance close to a project’s end date is a common closeout risk flag, since it signals spending that is committed but not yet resolved.

Frequently Asked Questions
What does ULO stand for?
ULO stands for unliquidated obligations — amounts a federal award recipient has legally committed to spend, through a contract, purchase order, or similar commitment, but has not yet actually paid out.
When does an obligation become liquidated?
An obligation becomes liquidated once the recipient actually pays the vendor, employee, or subrecipient it owes. Before that payment happens, the committed amount remains classified as unliquidated.
What’s the difference between unliquidated obligations and outlays?
On the Federal Financial Report (SF-425), total federal obligations are split into outlays (amounts already disbursed) and unliquidated obligations (amounts still legally committed but not yet paid). Outlays show what has physically gone out the door; unliquidated obligations show what is already promised but still pending.
Why do unliquidated obligations matter at award closeout?
At closeout, a recipient must generally liquidate all obligations and submit final financial reports within a set window after the period of performance ends. A large unliquidated-obligations balance close to a project’s end date is a common risk flag, since it signals spending that is committed but not yet resolved.
How long does a recipient have to liquidate obligations after the period of performance ends?
For most federal awards, 2 CFR 200.344 sets a 120-calendar-day window after the period of performance ends for a recipient to liquidate obligations and submit final financial reports as part of closeout.

"description": "An unliquidated obligation (ULO) is the portion of a federal award's obligated funds that has been legally committed through an obligating action -- such as a purchase order, contract, or subaward agreement -- but for which payment has not yet been made (on a cash-basis report) or the corresponding expenditure has not yet been recorded (on an accrual-basis report). Under 2 CFR 200.1, a 'financial obligation' is created by orders placed for property and services, contracts and subawards made, and similar transactions requiring payment under a Federal award. An 'unliquidated financial obligation' is that same committed amount before it is liquidated -- i.e., before the recipient or subrecipient actually pays it (cash basis) or records the expenditure (accrual basis). A dollar only becomes a ULO once an obligating action has occurred; funds that are merely available but not yet committed to any specific order, contract, or subaward are instead part of the award's unobligated balance, not a ULO.",
