NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) 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. Net revenues by geographic area are presented based upon the country of destination and are as follows (in thousands): GEOGRAPHIC INFORMATION Fiscal Years Ended September 30, 2011 October 1, 2010 October 2, 2009 United States ..................................... $ 76,764 $ 115,610 $ 76,435 Other Americas ................................... 38,863 36,724 26,078 Total Americas ................................. 115,627 152,334 102,513 China ........................................... 914,678 628,858 414,208 South Korea ..................................... 148,370 144,758 174,744 Taiwan ......................................... 93,753 51,353 48,443 Other Asia-Pacific ................................ 91,521 30,922 23,098 Total Asia-Pacific ............................... 1,248,322 855,891 660,493 Europe, Middle East and Africa ...................... 54,973 63,624 39,571 $1,418,922 $1,071,849 $802,577 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.
