Wah Shing was a subsidiary of a Hong Kong public toy manufacturer. It was a company with annual revenues of U.S.$40 million (the average Hong Kong toy company with product line similar to Wah Shing's earned about U.S.$30 million in revenues per year). While at his previous employer, Perez had worked with Wah Shing. Wah Shing had been one of the suppliers of choice for major toy companies such as Tiger and Hasbro, which needed electronic toys. These companies wanted to maintain their track record of successful electronic toy engineering development and manufacture in the electronic hand-held, feature electronic plush, radio control and IR interactive categories, including toys such as Shotgun and Skidzo, Furby, Laser Light Tennis, and Galactic Battle. Wah Shing employed 3,500 people in its 100,000-square-foot factory, counting six engineers on its staff. Although Harary had toured the factory, during his visit, he had been unable to meet the owner, who was traveling. By observation, Harary estimated that Wah Shing was at 70 to 80 percent of capacity at its Chinese factory, which was located five hours away from Hong Kong
