Public higher education has grown to appreciate added support from charitable gifts. Philanthropic support for public higher education reaches back to the early 1900s, when public universities needed funding assistance to build campus facilities because state funds were stretched thin. To facilitate the process of acquiring, receiving, and processing gifts, and managing and investing those charitable resources, universities established institutionally related foundations (IRFs). Universities have grown to rely on charitable gifts for annual operational supplements, capital purposes, or endowed funds. Building endowments to deliver a recurring source of support in perpetuity became an attractive resource as state budgets were strained for other broadening social priorities. One could view charitable resources as the third leg of the stool for funding a public institution, along with tuition and fees as well as grants. To be certain, these are unequal legs, but they have emerged as essential sources. As seasoned professionals responsible for building philanthropy programs know so well, the return on the investment can take months or years. However, if the investment is delayed or does not use every source available, the return will be less than the potential and slower to materialize than expected or required. To make money requires an investment, and the return on investment can in turn support the IRF. In this chapter, the author discusses the different sources for funding the IRF and the pros and cons of these sources. (Contains 1 table.)
