KFC Corporation is the largest fast-food chicken operator, developer, and franchiser in the world. KFC, a wholly owned subsidiary of PepsiCo, Inc. until late 1997, operates over 5,000 units in the United States, approximately 60 percent of which are franchises. Internationally, KFC has more than 3,700 units, of which two-thirds are also franchised. In addition to direct franchising and wholly owned operations, the company participates in joint ventures, and continues investigating alternative venues to gain market share in the increasingly competitive fast-food market. In late 1997 the company expected to become a wholly owned subsidiary of Tricon Global Restaurants, Inc., to be formed from the spin off of PepsiCo's restaurant holdings.
