17. Operating Segment Information
As a consequence of the Companys focus on developing products that can address multiple end markets and market demand for products that contain more than one element of SMSCs technology solutions, and the impact that these trends have had on the management of the Companys business and internal reporting, since the quarter ending November 30, 2005 the Company has concluded that it operates and reports as a single business segment the design, development, and marketing of semiconductor integrated circuits. This change had no impact on the Companys disclosure because it previously aggregated the results of operating segments into one reportable segment under the aggregation criteria set forth in SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information.
