Syco is a diversified company that has six primary lines of business. Fifty percent of its revenues and 18 percent of its profits come from retailing. Most of its retail outlets are discount department stores that serve as anchor tenants for large suburban shopping malls. The remaining businesses are broken out as follows: Insurance accounts for 30 percent of revenues and 50 percent of profits; consumer credit card operations are 6 percent of sales and 17 percent of profits; 5 percent of revenues and 6 percent of profits come from its stock brokerage business; commercial and residential real estate operations generate 4 percent of sales and 8 percent of profits; finally, 5 percent of revenues and 1 percent of profits come from its online portal business. The company's management states that all these businesses are essential to its competitive future.
