Segment Reporting [Abstract]

Segment Information

SEGMENT INFORMATION AND CONCENTRATIONS

In accordance with ASC 280-Segment Reporting ("ASC 280"), the Company has one reportable operating segment which designs, develops, manufactures and markets proprietary semiconductor products, including intellectual property. ASC 280 establishes standards for the way public business enterprises report information about operating segments in annual financial statements and in interim reports to shareholders. The method for determining what information to report is based on management's use of financial information for the purposes of assessing performance and making operating decisions. In evaluating financial performance and making operating decisions, management primarily uses consolidated net revenue, gross profit, operating profit and earnings per share. The Company's business units share similar economic characteristics, long term business models, research and development expenses and selling, general and administrative expenses. In light of the recent acquisitions, the Company reassessed its operations and concluded that there has been no change and the Company continues to consider itself to have one reportable operating segment at September 30, 2011. The Company will re-assess its conclusions at least annually.

The Company’s revenues by geography do not necessarily correlate to end market demand by region. For example, if the Company sells a power amplifier module to a customer in South Korea, the sale is recorded within the South Korea account although that customer, in turn, may integrate that module into a product sold to an end customer in a different geography.

Net property, plant and equipment balances, including property held for sale, based on the physical locations within the indicated geographic areas are as follows (in thousands):

	As of

CONCENTRATIONS

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of trade accounts receivable. Trade accounts receivables are primarily derived from sales to manufacturers of communications and consumer products and electronic component distributors. Ongoing credit evaluations of customers’ financial condition are performed and collateral, such as letters of credit and bank guarantees, are required whenever deemed necessary.

In both fiscal years 2011 and 2010 the Company had three customers, each with greater than ten percent of net revenue; Foxconn, Nokia and Samsung Electronics. In fiscal years 2009 the Company's greater than ten percent customers were Asian Information Technology, Samsung Electronics and Sony Ericsson Mobile Communications.

The Company's greater than ten percent customers comprised the following percentages of net revenue:
