If you are collaborating with researchers at another institution on a proposal and IU is the lead institution, a subaward may be required.
A subaward (also referred to as a subgrant or subcontract) is financial support from a prime awardee (e.g., Indiana University) to a qualified organization for performance of a substantive portion of the programmatic effort under the prime award. Subaward agreements are negotiated between the two institutions after the prime award is received.
