RIDF stands for Recovery of Improperly Disbursed Funds. USAC uses it when it discovers that funds were disbursed in error, but the original decision to commit those funds was correct. USAC gives its own example: an invoice that mixed eligible and ineligible items, USAC pays it, then recovers only the cost of the ineligible items.
How It Works
RIDF is USAC's answer to a narrower problem than a COMAD. With RIDF, nothing was wrong with the commitment itself, the FRN was correctly funded, but a specific payment on it went out incorrectly, most often because an invoice bundled in something that wasn't actually eligible alongside the approved products or services.
Because the commitment decision was sound, USAC generally doesn't need to adjust the FRN's commitment amount to fix a RIDF issue. It simply recovers the specific improperly disbursed amount from the responsible party. Once that money is returned to USAC, USAC resumes paying any further valid invoices submitted against that same FRN for approved, eligible products and services.
USAC describes RIDF on the same page it uses for COMAD: Commitment Adjustments/Recoveries. For the broader picture of how RIDF fits alongside COMAD, PQA, and BCAP, see our audits and adjustments guide.
What This Means for You
Applicants
A RIDF notice doesn't mean your funding request was flawed, it means one specific invoice or line item was. Review the itemized explanation closely rather than assuming a broader problem with the FRN.
Service Providers
RIDF is most often triggered by exactly what got billed, not what got approved. Keep invoice line items clean and clearly mapped to the eligible costs on the FRN, since a single ineligible item mixed into an otherwise valid invoice is enough to trigger recovery.
RIDF gets far less attention than COMAD, but in practice it's the more common everyday correction, precisely because it doesn't come with the drama of a rescinded commitment. That quietness is exactly why it's worth watching: it's a signal that invoice line-item eligibility still matters after a funding request is committed, not just at the filing stage.
Common Questions About RIDF
What does RIDF stand for?
Recovery of Improperly Disbursed Funds, USAC's process for recovering a specific disbursement error without necessarily changing the underlying funding commitment.
How is RIDF different from a COMAD?
COMAD means the commitment decision itself was wrong and USAC rescinds or adjusts the commitment. RIDF means the commitment was correct, but a specific disbursement wasn't, so USAC recovers just that disbursement.
Does a RIDF action change my FRN's commitment amount?
Generally no. That's the defining difference from a COMAD: the commitment stays as originally approved, and only the improperly disbursed amount is recovered.
What triggers RIDF instead of a full COMAD?
A correct commitment decision paired with a disbursement error, such as an ineligible line item mixed into an otherwise valid and properly approved invoice.
What happens to future invoices on that FRN while a RIDF is pending?
USAC resumes paying valid invoices submitted for that FRN, for approved, eligible products and services, once the improperly disbursed amount has been returned to USAC.
