Question

If the F&A rate changes between the time of proposal and award or during the course of a project, which F&A rate should be used?

Answer

The F&A rate used in the proposal budget will be honored upon award if the F&A rate changes prior to award. Once awarded, the F&A rate remains fixed for the life (competitive segment) of the award including subsequent supplemental increments of funding (Supplement) on the same award. Continuations and Renewals should use the rate in effect at the time of submission.
