20.	GEOGRAPHIC AND SEGMENT INFORMATION

In connection with the acquisition of SST, the Company re-evaluated its segment reporting, based on the nature of the products and services provided to customers, and the information provided to the Company's chief operating decision maker. Based on that evaluation, the Company determined its reporting segments include semiconductor products and technology licensing. The technology licensing segment is a result of the acquisition of SST, and thus for fiscal years ended March 31, 2010 and 2009, net sales and gross profit are solely attributable to the semiconductor product segment. The Company does not allocate operating expenses, interest income, interest expense, other income or expense, or provision for or benefit from income taxes to these segments for internal reporting purposes, as the Company does not believe that allocating these expenses is beneficial in evaluating segment performance. Additionally, the Company does not allocate assets to segments for internal reporting purposes as it does not manage its segments by such metrics.

The following table represents revenues and gross profit for each segment (in thousands):

	Year Ended March 31, 2011
	Net Sales		Gross Profit
Semiconductor products	$	1,415,137	$	806,398
Technology licensing		72,068		68,038
	$	1,487,205	$	874,436

The Company sells its products to distributors and original equipment manufacturers (OEMs) in a broad range of market segments, performs on-going credit evaluations of its customers and, as deemed necessary, may require collateral, primarily letters of credit. The Company's operations outside the U.S. consist of product assembly and final test facilities in Thailand, and sales and support centers and design centers in certain foreign countries. Domestic operations are responsible for the design, development and wafer fabrication of products, as well as the coordination of production planning and shipping to meet worldwide customer commitments. The Thailand assembly and test facility is reimbursed in relation to value added with respect to assembly and test operations and other functions performed, and certain foreign sales offices receive compensation for sales within their territory. Accordingly, for financial statement purposes, it is not meaningful to segregate sales or operating profits for the assembly and test and foreign sales office operations. Identifiable long-lived assets (consisting of property, plant and equipment) by geographic area are as follows (amounts in thousands):

	March 31,
	2011		2010
United States	$	330,046	$	332,920
Thailand		193,729		147,732
Various other countries		16,738		12,387
Total long-lived assets	$	540,513	$	493,039

Sales to unaffiliated customers located outside the U.S., primarily in Asia and Europe, aggregated approximately 80%, 77% and 75% of consolidated net sales for the years ended March 31, 2011, 2010 and 2009, respectively. Sales to customers in Europe represented 23%, 25% and 29% of consolidated net sales for the years ended March 31, 2011, 2010 and 2009, respectively. Sales to customers in Asia represented 57%, 51% and 46% of consolidated net sales for each of the years ended March 31, 2011, 2010 and 2009, respectively. Sales into China, including Hong Kong, represented 25%, 25% and 23% of consolidated net sales for the years ended March 31, 2011, 2010 and 2009, respectively. Sales into Taiwan represented 13% of consolidated net sales for the year ended March 31, 2011, and 10% of consolidated net sales for the year ended March 31, 2010. Sales into any other individual foreign country did not exceed 10% of the Company's net sales for any of the years presented.

The Company's largest distributor accounted for approximately 10% of its net sales in fiscal 2011, approximately 12% of its net sales in fiscal 2010, and approximately 14% of its net sales in fiscal 2009.
