Segment Reporting [Abstract]

Geographic and Segment Information

Geographic and Segment Information

The Company's reporting segments include semiconductor products and technology licensing.  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 (amounts in thousands):

	Years ended March 31,
	2017				2016				2015
	Net Sales		Gross Profit		Net Sales		Gross Profit		Net Sales		Gross Profit
Semiconductor products	$	3,316,651	$	1,666,040	$	2,084,210	$	1,116,340	$	2,057,443	$	1,139,971
Technology licensing	91,156		91,156		89,124		89,124		89,593		89,593
Total	$	3,407,807	$	1,757,196	$	2,173,334	$	1,205,464	$	2,147,036	$	1,229,564

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 Company's 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 net of accumulated amortization) by geographic area are as follows (amounts in thousands):

	March 31,
	2017		2016
United States	$	388,537	$	373,860
Thailand	210,603		182,813
Various other countries	84,198		52,723
Total long-lived assets	$	683,338	$	609,396

Sales to unaffiliated customers located outside the U.S., primarily in Asia and Europe, aggregated approximately 84% of consolidated net sales for each of fiscal 2017, 2016 and 2015.  Sales to customers in Europe represented approximately 24% of consolidated net sales for fiscal 2017, approximately 22% of consolidated net sales for fiscal 2016, and approximately 21% of consolidated net sales for fiscal 2015.  Sales to customers in Asia represented approximately 58% of consolidated net sales for 2017, and approximately 59% of consolidated net sales in each of fiscal 2016 and 2015.  Within Asia, sales into China, including Hong Kong, represented approximately 32%, 30% and 28% of consolidated net sales for fiscal 2017, 2016 and 2015, respectively. Sales into Taiwan represented approximately 9%, 12% and 14% of consolidated net sales for fiscal 2017, 2016 and 2015, respectively. Sales into any other individual foreign country did not exceed 10% of the Company's net sales for any of the three years presented.

No single end customer or distributor accounted for 10% or more of the Company's net sales during fiscal 2017, 2016 or 2015.
