UMC Public Statement

 

1. Date of occurrence of the event:2005/06/22

 

2. Cause of occurrence:

 

UMC Requests that the Hsinchu Prosecutor’s Office Brings Charges Against Chairman Tsao Without Delay in Order to Bring Closure to the UMC-Hejian Affair

 

On Feb. 15th of this year, more than 120 investigators of the Hsinchu prosecutors’ office initiated a large-scale search of UMC taking away countless documents and subsequently questioning numerous UMC and Hejian employees on multiple occasions. The pretence for the investigation was the protection of the interests of UMC’s shareholders from a management breach of trust. The investigation focused on the relationship between UMC and Hejian, resulting in a tremendous amount of attention due the highly politicized nature of cross-strait relations.

 

UMC immediately agreed to fully cooperate with the investigation. Currently, the major accusations of the investigators have been clarified by UMC, and there has been no evidence uncovered to show that UMC has illegally invested in Hejian, transferred orders to Hejian, or authorized Hejian to use its patents, or committed any other crimes suspected by the prosecutors. As far as the matter of technology transfer is concerned, the company has not done anything improper, but since issues related to technology are beyond the ready comprehension of the prosecutor’s office, it has taken some time to clarify this issue, but UMC remains optimistic towards the outcome.

 

At the latest shareholders meeting, Chairman Tsao was asked to explain the current investigation to shareholders. During his talk, he went on to explain his meeting with ROC President Chen on January 25th of this year. He also mentioned a promise from the President to give any assistance needed related to the possible future merger of Hejian. Chairman Tsao chose to mention this meeting at the shareholders meeting in order to illustrate his previous statement that UMC had already considered the idea of merging Hejian before the start of the investigation by the prosecutor’s office, and that UMC’s claims were in no way influenced by the investigation. Furthermore, at the same shareholders meeting, the shareholders unanimously passed a proposal that stated that the UMC management team’s past assistance to Hejian was in the best long-term interest of the company and in no way constituted a breach of trust by the management team. With the full trust and support of our shareholders, we are confident that this incident can be brought to a satisfactory conclusion in the near future.

 

Unexpectedly, several media sources attempted to scandalize the Chairman’s revelation of his meetings with President Chen. Further reports claimed that the President’s office denied that any such discussion took place. Chairman Tsao has since clarified that at the time of his meeting with


LOGO   www.umc.com

 

President Chen, he did in fact mention Hejian, but that it was not the major topic of their discussion. The main topic of discussion was the existence of certain legal gray areas that made it impossible to ascertain whether it was possible for an overseas subsidiary of the company to merge Hejian. The President promised to give assistance in clarifying this legal gray area, although he did not refer to assisting with any particular case. Due to the busy nature of the presidency and the fact that the investigation into the relationship between UMC and Hejian had not begun at the time, it is possible that the President does not have a strong impression or recollection of the topic of discussion.

 

Over the last months, the UMC-Hejian affair has become highly politicized and resulted in widespread social discourse and debate on whether or not the prosecutor’s office will press formal charges against anyone. In order to avoid any future public conflict or opposition related to this incident, UMC respectfully requests that the Hsinchu prosecutor’s office presses charges against UMC chairman Robert Tsao for all suspected crimes in the quickest manner possible. Since the prosecutor’s office operates under the supervision of the Administrative offices, it is unavoidable that people will suspect political involvement, and the company believes that only by undergoing the due process of the judicial system will it finally be possible to put an end to the rumors and speculation associated with this case. In order to facilitate the court in making an impartial decision in this case, Chairman Tsao delivered his resignation from the position of National Policy Advisor to the President’s office on June 21.

 

Since the shareholders have confirmed that UMC’s assistance to Hejian was not a breach of trust, it is not possible that the entire management team committed a group breach of trust. The company’s position is that all of the employees working under Chairman Tsao were merely acting upon his instructions and should be cleared of any charges.

 

On June 9th, while communicating with the prosecutor’s office, Chairman Tsao asked the prosecutor Mr. Chen Rong Lin what it would take to have the travel restrictions placed on Hejian CEO Mr. Hsu Jien Hwa lifted. The prosecutor answered that it was not his decision to make and would take the agreement of his superiors. The chairman then asked what it would take to get the agreement of the superiors. To this, the prosecutor mentioned three points: 1) a public consensus; 2) the maintenance of legal authority; 3) and to have bail set at a extremely high figure since Hsu Jien Hwa was a major economic criminal. We do not know to which superiors the prosecutor has referred, and we question their authority to overstate the situation to the point that Hsu Jien Hwa is declared a major economic criminal and to set conditions that no one could possibly satisfy. This abuse of authority is a clear and sustained violation of Hsu Jian Hwa’s right to return to his job at Hejian. In a country ruled by law such as Taiwan, it should not be possible for the Hsinchu prosecutor to violate the rights of an individual in this manner.

The company’s request for the Hsinchu prosecutor’s office to press charges against Chairman Tsao as quickly as possible is no empty gesture. The Chairman has already stated that he will resign from his position if found guilty on any charges. He has also stated that he will recommend to the board of directors that CEO Dr. Jackson Hu take over the position of Chairman upon his departure. The chairman has also stated his strong approval for Dr. Hu’s ability and character, and said that he has excelled in his duties since taking the position of CEO, receiving strong positive response from both UMC’s customers and UMC employees. Chairman Tsao strongly believes that Dr. Hu is the appropriate person to lead the future growth of the company, and has decided that, regardless of the outcome of the UMC-Hejian affair, he will retire from the position of Chairman before the Annual Shareholders Meeting to be held in 2007 in order to recommend Dr. Hu to the position of Chairman.

 

Finally, the company would also like to express its gratitude to all of those who have shown their concern and support throughout this incident.
