180 United Microelectronics Corporation Annual Report 2004 Special Disclosures 181 Status of Internal Control 182 Acquisition or Disposal of UMC Shares by Subsidiaries 183 Major Resolutions of the Shareholders’ Meeting and the Board of Directors’ Meetings
Special Disclosures 181 Status of Internal Control Statement of Internal Control The self-assessment of UMC’s internal control was conducted for the year ended December 31, 2004 based on UMC’s internal control system. The results are described as follows: 1. UMC acknowledges that the Board of Directors and the management are responsible for establishing, executing and maintaining a sufficient internal control system, which has been already set up. The purposes of the internal control system are to provide a reasonable assurance of achieving the goals of efficiency and effectiveness of the operations, such as profitability, performance and the safeguard of the assets, the reliability of the financial reports and the compliance with the applicable laws and regulations. 2. The internal control system has its inherent constraints, and it could only provide reasonable assurance of achieving the three goals mentioned above no matter how well it has been designed. The effectiveness of the internal control system could be changed due to changes of the environment and the situations. UMC has established an internal control system with the function of self-monitoring which could undertake corrective actions whenever a shortcoming is identified. 3. UMC’s assessment of the effectiveness of the design and execution of the internal control system is based on the Standards governing the establishment of internal control system by public companies (the Standards), which specify the judgement items for evaluating the effectiveness of internal control. The internal control is divided into five components, based on the process of management control, according to the judgement items for internal control employed by the Standards, such as: (1) Control Environment, (2) Risk Assessments, (3) Control Activities, (4) Information and Communication, and (5) Monitoring. Each component consists of certain items, which could be referred to the Standards. 4. UMC has employed the judgement items mentioned above to evaluate the effectiveness of the design and execution of the internal control system. 5. UMC believes that the effectiveness of the design and execution of its internal control system (including subsidiaries) during the above mentioned assessment period provides reasonable assurance of achieving the goals of acknowledging the efficiency and effectiveness of operations, the reliability of financial reports and the compliance with applicable laws and regulations. 6. The Statement of Internal Control will be an integral part of UMC’s annual report and prospectus that are open to the public, and within which any illegal acts, such as misstatement or concealment, would subject to the legal liabilities of Code 20, Code 32, Code 171 and Code 174 of the Securities Exchange Laws. 7. UMC’s Board of Directors has approved the Statement of Internal Control (the Statement) on March 17, 2005. 9 directors attended and agreed with the content of the Statement. Robert H.C. Tsao, Chairman March 17, 2005 Jackson Hu, CEO The Company was not required to engage with a CPA to attest to the internal control system; therefore there is no CPA audit report on internal control to be disclosed for 2004.
