Our \"major donors\" account for less than five percent of our total income. Also, for a non-profit, we have quite a diversified portfolio of revenue. Just over forty percent is cash from private citizens; thirty percent is government grants in food and cash; and about thirty percent are products donated from corporation--what we call \"gifts-in-kind.\"" } ] } }
