This is a fascinating approach to solving one of the greatest problems charities face: negative public perception of "overhead". People react extremely negatively when a charity has any significant percentage of donations going to overhead, which makes it very difficult for charities to invest in themselves to improve efficiency and promote growth. By donating "efficiency", Toyota is doing the equivalent of donating money to charities but in a way that allows them to use it for overhead without it actually being labeled as such. Brilliant!
