The trustees shall, by July 1, 1983, develop and implement guidelines to ensure that auxiliary organizations classified as foundations for sponsored programs, workshops, and institutes maintain fiscal viability. These guidelines shall specify how reimbursement received by a foundation for indirect costs in connection with the performance of grants or contracts which exceeds the indirect costs actually incurred by the foundation for those grants or contracts shall be divided between the foundation and the campus of the California State University which the foundation serves, in a manner consistent with the educational mission of the university.
