competition, capital adequacy, general economic conditions and the potential inability to raise additional capital if required; the risk that the Company will be unsuccessful in gauging fashion trends and changing customer preferences; the risk that changes in general economic conditions, consumer confidence, or consumer spending patterns will have a negative impact on the Company’s financial performance; the highly competitive nature of the Company’s business in the United States and internationally and its dependence on consumer spending patterns, which are influenced by numerous other factors; the Company’s ability to respond to the business environment and fashion trends; continued acceptance of the Company’s brands in the marketplace; and other risks.
