CUSTOMERS

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. No sales to an individual customer accounted for more than 10% of fiscal year 2007 revenue. Sales to Dell and its subsidiaries accounted for approximately 11% and 10% of fiscal year 2006 and 2005 revenue, respectively. These sales were made primarily through our OEM and volume licensing channels and cover a broad array of products including Windows PC operating systems, Microsoft Office, and server products. Our practice is to ship our products promptly upon receipt of purchase orders from customers; consequently, backlog is not significant.
