UW is the subrecipient. Our sponsor is the institution receiving the prime award and is issuing a subaward to the UW funding.
For example: National Science Foundation (NSF) awards a project to UCSD. UCSD awards some of that funding to the UW to complete a portion of the work on their project.
UCSD is the sponsor (pass through entity) on the eGC1 to the UW. NSF is the prime sponsor.
