Integrity has always been our most important core value and asset. The practice of our core values is crucial for the success of the company. Therefore, based on the Code of Conduct for Integrity Management, the "Code of Business Conduct and Ethics" was enacted on July 1, 2019, which clearly guides the ethical standards of various duties and activities. The company expects every colleague to conduct all business in accordance with the regulations, treating trading counterparties fairly and impartially. Richtek has a zero-tolerance policy for violations of ethical standards of conduct, especially for corruption, bribery, unfair competition, leakage of confidential information, and insider trading. Richtek explicitly states in relevant important regulations, work rules, and commitment documents that it strictly adheres to the moral discipline of integrity and honesty, requiring all employees to do the right thing in the right way and abide by the ethical standards of conduct specified in the regulations in all of their duties and activities, especially when dealing with any matters related to trading counterparties. The Human Resources Department is responsible for the Code of Business Conduct and Ethics as the dedicated unit, conducting regular reviews, modifications, and explanations, and the internal audit unit is responsible for supervising implementation.
