Note 14. Geographic Information and Concentrations of Risk

The Company operates exclusively in the semiconductor industry and primarily within the analog and mixed-signal sector.

In fiscal year 2012, the Company reorganized its product lines. The components of the Advanced Communications and Sensing reporting unit were split into two reporting units consisting of the Advanced Communications and the Wireless and Sensing reporting units. The Company continues to report under one reportable segment. The table below provides net sales activity by product line on a comparative basis for all periods.

	Fiscal Year Ended

Long-lived Assets

Long-lived assets which consist of property, plant and equipment, net of accumulated depreciation are summarized as follows:

(in thousands)	January 29, 2012		January 30, 2011

	$	69,713	$	56,778

Some of these assets are at locations owned or operated by the Company's suppliers. The Company has consigned certain equipment to a foundry based in China to support its specialized processes run at the foundry. The Company has also installed its own equipment at some of its packaging and testing subcontractors in order to ensure a certain level of capacity, assuming the subcontractor has ample employees to operate the equipment.

The amount of equipment and machinery consigned to a foundry in China was $9.4 million and $7.2 million as of January 29, 2012 and January 30, 2011, respectively.

Significant Customers

Sales to the Company's customers are generally made on open account, subject to credit limits the Company may impose, and the receivables are subject to the risk of being uncollectible.

Each of the following significant customers accounted for at least 10% of our net sales for the periods indicated:

The following table shows the list of customers that have an outstanding receivable balance that represents at least 10% of our total net receivables for the periods indicated:

(percentage of net accounts receivable)

Outside Subcontractors and Suppliers

The Company relies on a limited number of outside subcontractors and suppliers for the production of silicon wafers, packaging and certain other tasks. Disruption or termination of supply sources or subcontractors, due to natural disasters such as the recent earthquake and Tsunami in Japan and floods in Thailand or other causes, could delay shipments and could have a material adverse effect on the Company. Although there are generally alternate sources for these materials and services, qualification of the alternate sources could cause delays sufficient to have a material adverse effect on the Company. Several of the Company's outside subcontractors and suppliers, including third-party foundries that supply silicon wafers, are located in foreign countries, including China, Taiwan, Singapore, Thailand, Malaysia, the Philippines, Germany, Japan, Israel and Canada. The Company's largest source of silicon wafers is an outside foundry located in China and a significant amount of the Company's assembly and test operations are conducted by third-party contractors in China, Malaysia, Thailand and the Philippines.
