Corporate Governance

Our Board of Directors has adopted Corporate Governance Guidelines to assist the Board in exercising its responsibilities. The guidelines reflect the Board's commitment to building long-term stockholder value with an emphasis on corporate governance.

Our Code of Ethics guides our officers, directors and employees in maintaining the highest standards of ethical conduct. All of our employees are required to carry out their duties in accordance with the policies set forth in the Code of Ethics and with applicable laws and regulations. We intend to satisfy the disclosure requirement regarding an amendment to, or waiver from, a provision of the Code of Ethics by posting such information here on our website.

On August 30, 2016, the Board of Directors of Seattle Genetics, Inc. (the “Company”) approved an amendment to the Company’s Code of Business Conduct and Ethics (the “Code”) to include therein the notice of immunity required by the Defend Trade Secrets Act of 2016, to include language specifically clarifying that neither the Code nor other Company policies or agreements impede the ability of employees to communicate with and to report violations or potential violations of law to governmental agencies and to make other technical clarifying changes.
