The gift should be complete, voluntary, and unconditional. The gift must be intended for public benefit rather than for private interest. The donor must relinquish control over the gifted item in order for us to fulfill the mission of the Foundation through the use, dissemination, or other disposal of the gift. Furthermore, a donor cannot unduly restrict the use of a gift. A contribution for a specific project, which is consistent with the mission of the Foundation, would generally be allowed. This is in contrast to a contract (i.e. exchange transaction) which is a written, often negotiated, agreement between the institution and the awarding agency and is enforceable by law. Responsibility under a contract normally involves the generation of some tangible product or service, such as a report of research, often for the exclusive or proprietary use of the contracting agency and subject to certain standards of performance and the expectation of economic benefit on the part of the grantor.
