Segment Disclosure [Abstract]

Segment Disclosure

Note 12. Segment Disclosure

ASC 280, Segment Reporting, requires disclosures of certain information regarding operating segments, products and services, geographic areas of operation and major customers. Segment reporting is based upon the "management approach," i.e., how management organizes the Company's operating segments for which separate financial information is (1) available and (2) evaluated regularly by the Chief Operating Decision Maker (CODM) in deciding how to allocate resources and in assessing performance. Synopsys' CODMs are the Company's Chief Executive Officer and Chief Operating Officer.

The Company provides software products and consulting services in the EDA software industry. The Company operates in a single segment. In making operating decisions, the CODMs primarily consider consolidated financial information, accompanied by disaggregated information about revenues by geographic region. Specifically, the CODMs consider where individual "seats" or licenses to the Company's products are used in allocating revenue to particular geographic areas. Revenue is defined as revenues from external customers. Goodwill is not allocated since the Company operates in one reportable operating segment. Revenues and property and equipment, net, related to operations in the United States and other by geographic areas were:

Geographic revenue data for multiregional, multi-product transactions reflect internal allocations and is therefore subject to certain assumptions and to the Company's methodology.

One customer, in the aggregate, accounted for 10.6%, 10.9%, and 10.8% of the Company's consolidated revenue in fiscal 2011, 2010 and 2009, respectively.
