19 Tizen * OS Compliance Tizen * OS Compliance 旨在确保移动设备实施能与应用共同运行移动设备实施 : 如果按照一个配置文件进行实施, 设备将向应用提供由该配置文件定义的一致行为, 并提供一致的用户体验应用 : 如果按照该规范进行构建, 应用将在部署了它所使用的 API 的兼容设备上运行如果必要, 可以将应用指向特定的配置文件 19

20 Tizen * OS Compliance 模型 Tizen * OS compliance 模型包括两个主要方面 : Tizen 通用平台 : 整套特性和 API 可以跨所有 Tizen 平台通用, 而且是各平台所需的通用平台旨在减少将兼容应用从一个设备配置文件迁移至另外一个配置文件的移植工作量, 并可最大限度地跨平台重复使用代码 Tizen 配置文件 : 位于 Tizen 通用平台顶层的特定设备类别的明确要求, 包括设备的其他组件 API 和硬件要求 20

21 Tizen * OS Compliance 配置文件目前的配置文件是移动设备 : 手机平板电脑会在将来推出其他配置文件, 可能包括 IVI: 车载信息娱乐系统电视 : DTV/STB/IPTV 系统翻盖式电脑 : 笔记本电脑摄像机 : 摄像机打印机 : 打印机 21

37 Risk Factors The above statements and any others in this document that refer to plans and expectations for the first quarter, the year and the future are forward-looking statements that involve a number of risks and uncertainties. Words such as anticipates, expects, intends, plans, believes, seeks, estimates, may, will, should and their variations identify forward-looking statements. Statements that refer to or are based on projections, uncertain events or assumptions also identify forward-looking statements. Many factors could affect Intel s actual results, and variances from Intel s current expectations regarding such factors could cause actual results to differ materially from those expressed in these forward-looking statements. Intel presently considers the following to be the important factors that could cause actual results to differ materially from the company s expectations. Demand could be different from Intel's expectations due to factors including changes in business and economic conditions; customer acceptance of Intel s and competitors products; supply constraints and other disruptions affecting customers; changes in customer order patterns including order cancellations; and changes in the level of inventory at customers. Uncertainty in global economic and financial conditions poses a risk that consumers and businesses may defer purchases in response to negative financial events, which could negatively affect product demand and other related matters. Intel operates in intensely competitive industries that are characterized by a high percentage of costs that are fixed or difficult to reduce in the short term and product demand that is highly variable and difficult to forecast. Revenue and the gross margin percentage are affected by the timing of Intel product introductions and the demand for and market acceptance of Intel's products; actions taken by Intel's competitors, including product offerings and introductions, marketing programs and pricing pressures and Intel s response to such actions; and Intel s ability to respond quickly to technological developments and to incorporate new features into its products. The gross margin percentage could vary significantly from expectations based on capacity utilization; variations in inventory valuation, including variations related to the timing of qualifying products for sale; changes in revenue levels; segment product mix; the timing and execution of the manufacturing ramp and associated costs; start-up costs; excess or obsolete inventory; changes in unit costs; defects or disruptions in the supply of materials or resources; product manufacturing quality/yields; and impairments of long-lived assets, including manufacturing, assembly/test and intangible assets. Intel's results could be affected by adverse economic, social, political and physical/infrastructure conditions in countries where Intel, its customers or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in currency exchange rates. Expenses, particularly certain marketing and compensation expenses, as well as restructuring and asset impairment charges, vary depending on the level of demand for Intel's products and the level of revenue and profits. Intel s results could be affected by the timing of closing of acquisitions and divestitures. Intel s current chief executive officer plans to retire in May 2013 and the Board of Directors is working to choose a successor. The succession and transition process may have a direct and/or indirect effect on the business and operations of the company. In connection with the appointment of the new CEO, the company will seek to retain our executive management team (some of whom are being considered for the CEO position), and keep employees focused on achieving the company s strategic goals and objectives. Intel's results could be affected by adverse effects associated with product defects and errata (deviations from published specifications), and by litigation or regulatory matters involving intellectual property, stockholder, consumer, antitrust, disclosure and other issues, such as the litigation and regulatory matters described in Intel's SEC reports. An unfavorable ruling could include monetary damages or an injunction prohibiting Intel from manufacturing or selling one or more products, precluding particular business practices, impacting Intel s ability to design its products, or requiring other remedies such as compulsory licensing of intellectual property. A detailed discussion of these and other factors that could affect Intel s results is included in Intel s SEC filings, including the company s most recent Form 10-Q, report on Form 10-K and earnings release.
