The Chili Appreciation Society International (CASI) sanctions over 550 cookoffs annually that raise over $1,000,000.00 for charity. Corporate CASI, which has the function of sanctioning all of these cookoffs, doing the necessary work to tabulate cookoff results, and putting on the annual Terlingua International Chili Championship, has an annual income of approximately $250,000.00.
