The Company sells its products to distributors and 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 managing 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 depreciation and ROU assets) by geographic area are as follows (in millions):
