Selling to the retail market is an important part of our business, and if we fail to maintain and grow our market share or gain market acceptance of our branded products, our operating results could suffer.
We sell our branded products directly to a select group of major retailers, for example, computer superstores and CE stores, and authorize sales through distributors to other retailers and online resellers. Our current retail customer base is primarily in the United States, Canada and Europe. We are facing increased competition from other companies for shelf space at major retailers, which could result in lower revenues. If we fail to successfully maintain a customer preference for Western Digital brand products or fail to successfully expand into multiple channels, our operating results may be adversely affected. In certain markets, we are trying to grow market share, and in the process may face strong competition, which could result in lower gross margins. We will continue to introduce new products in the retail market that incorporate our disk drives. There can be no assurance that these products gain market acceptance, and if they do not, our operating results could suffer.
