Bribery and Corruption

Bribery means giving or receiving an unearned reward to influence someone's behavior. One common form of bribery is a "kickback" which is an unearned reward following favorable treatment. Corruption is any unlawful or improper behavior that seeks to gain an advantage through illegitimate means. Facilitating payments are payments made to officials with the intention of expediting an administrative process. Conflicts of interest are situations in which a person is in a position to derive personal benefit from actions or decisions made in their official capacity.

Tetra Tech's policy does not allow for corrupt practices in any form. Bribery is an illegal, criminal offense and violates the Corporate Code of Conduct Policy. Tetra Tech employees should avoid situations in which their private interests or those of their family members conflict or appear to conflict with the interests of the Company. Employees may not solicit or accept salaries, fees, commissions or any other item of value from contractors, suppliers, customers, consultants, or other persons and organizations doing business with the Company. For more information on our policies regarding bribery and corruption including gifts, meals, entertainment, political contributions, kickbacks, improper payments, and conflicts of interest, please see our Corporate Code of Conduct Policy.

Tetra Tech is subject to the terms and requirements of the Foreign Corrupt Practices Act ("FCPA"), which is part of the Securities Exchange Act of 1934, as amended. The FCPA generally prohibits payments by companies and their representatives to foreign (i.e., non-U.S.) government and quasi-government officials to secure business. While this policy is based on a United States law, all employees of Tetra Tech need to be in compliance with this policy. It is the Company's policy to comply fully with the requirements of the FCPA.
