Expanded Authorities
Expanded authorities are the operating authorities provided to grantees under certain research grant mechanisms that waive sponsor prior approval for specified actions. For a list of allowable expanded authority actions by federal sponsor click here.

Carryover
In many instances, an unobligated balance may be carried over into the next budget period without sponsor approval. If this is the case, it will be indicated as such in the Notice of Grant Award.

NIH prior approval is required for carryover of unobligated balances on the following: all P mechanisms except P01s; cooperative agreements (U mechanisms); National Research Service Awards (T and F mechanisms); Phase I SBIR and STTR (R43 and R41 mechanisms); clinical trials (regardless of mechanism) and awards to individuals.

Where carryover requires sponsor approval and/or when it exceeds 25% of the award, or when it exceeds $250,000, the request should be initiated by the PI through the progress report. In the justification section, and in the progress report itself, the PI should provide sufficient programmatic reasoning for the request. There should also be an explanation on how these funds will be applied to the program in the near future.
