In addition to the loss of sponsors including Zildjian and Vic Firth, makers of cymbals and drum sticks, respectively, the nonprofit says it lost $113,000 in withdrawn donations. The single largest loss in revenue came from its US Bands program, which runs about 150 high school marching band competitions across the country each year. It claims numerous bands did not participate this year because of Hopkins' association with US Bands, resulting in lost fees and ticket sales totaling nearly $850,000.
