Our customers include individual consumers, small and medium-sized organizations, enterprises, governmental institutions, educational institutions, Internet Service Providers, application developers, and OEMs. Consumers and small and medium-sized organizations obtain our products primarily through resellers and OEMs. Sales to Dell and its subsidiaries in the aggregate accounted for approximately 10% of fiscal 2004 revenue. These sales were made primarily through our OEM and volume licensing channels. No single customer accounted for more than 10% of revenue in 2002 or 2003. Our practice is to ship our products promptly upon receipt of purchase orders from customers; consequently, backlog is not significant.
