Segment Reporting [Abstract]

Segment and Enterprise-Wide Disclosures

9. Segment and Enterprise-Wide Disclosures

The FASB establishes standards for reporting information regarding operating segments in financial statements. Operating segments are identified as components of an enterprise about which separate, discrete financial information is evaluated by the chief operating decision-maker in making decisions on how to allocate resources and assess performance. We view our operations and manage our business as one operating segment. No discrete operating information is prepared by us except for product sales by product line and by legal entity for local reporting purposes.

Most of our revenues were generated in the United States, Germany, Japan, Canada, and other European countries, and substantially all of our assets are located in the United States. Net sales to unaffiliated customers by country were as follows:
