This business is rapidly evolving and intensely competitive, and is subject to changing technologies, shifting user needs, and frequent introductions of new products and services. The research and development of new, technologically advanced products is a complex and uncertain process requiring high levels of innovation and investment, as well as the accurate anticipation of technology, market trends and consumer needs. The number of people who access the Internet is increasing dramatically and a failure to attract and retain a substantial number of such users to a company’s products and services or to develop products and technologies that are more compatible with alternative devices, could adversely affect operating results. Concerns regarding a company’s products, services or processes that may compromise the privacy of users or other privacy related matters, even if unfounded, could damage a company’s reputation and adversely affect operating results. Catalog and mail order house companies may be exposed to significant inventory risks that may adversely affect operating results due to, among other factors: seasonality, new product launches, rapid changes in product cycles and pricing, defective merchandise, changes in consumer demand and consumer spending patterns, or changes in consumer tastes with respect to products. Demand for products can change significantly between the time inventory or components are ordered and the date of sale.
