****************************************

the company generally does not indemnify end-users of its operating system and application software against legal claims that the software infringes third-party intellectual property rights . other agreements entered into by the company sometimes include indemnification provisions under which the company could be subject to costs and/or damages in the event of an infringement claim against the company or an indemnified third-party . however , the company has not been required to make any significant payments resulting from such an infringement claim asserted against itself or an indemnified third-party and , in the opinion of management , does not have a potential liability related to unresolved infringement claims subject to indemnification that would have a material adverse effect on its financial condition or operating results . therefore , the company did not record a liability for infringement costs as of either september 29 , 2007 or september 30 , 2006 . concentrations in the available sources of supply of materials and product certain key components including , but not limited to , microprocessors , enclosures , certain lcds , certain optical drives , and application-specific integrated circuits ( 2018 2018asics 2019 2019 ) are currently obtained by the company from single or limited sources which subjects the company to supply and pricing risks . many of these and other key components that are available from multiple sources including , but not limited to , nand flash memory , dram memory , and certain lcds , are at times subject to industry-wide shortages and significant commodity pricing fluctuations . in addition , the company has entered into certain agreements for the supply of critical components at favorable pricing , and there is no guarantee that the company will be able to extend or renew these agreements when they expire . therefore , the company remains subject to significant risks of supply shortages and/or price increases that can adversely affect gross margins and operating margins . in addition , the company uses some components that are not common to the rest of the global personal computer , consumer electronics and mobile communication industries , and new products introduced by the company often utilize custom components obtained from only one source until the company has evaluated whether there is a need for and subsequently qualifies additional suppliers . if the supply of a key single-sourced component to the company were to be delayed or curtailed , or in the event a key manufacturing vendor delays shipments of completed products to the company , the company 2019s ability to ship related products in desired quantities and in a timely manner could be adversely affected . the company 2019s business and financial performance could also be adversely affected depending on the time required to obtain sufficient quantities from the original source , or to identify and obtain sufficient quantities from an alternative source . continued availability of these components may be affected if producers were to decide to concentrate on the production of common components instead of components customized to meet the company 2019s requirements . finally , significant portions of the company 2019s cpus , ipods , iphones , logic boards , and other assembled products are now manufactured by outsourcing partners , primarily in various parts of asia . a significant concentration of this outsourced manufacturing is currently performed by only a few of the company 2019s outsourcing partners , often in single locations . certain of these outsourcing partners are the sole-sourced supplier of components and manufacturing outsourcing for many of the company 2019s key products , including but not limited to , assembly .
