Supply Chain Transparency Statement

California Transparency in Supply Chains Act Disclosure (SB 657)

The California Transparency in Supply Chains Act of 2010 (SB 657) requires companies that manufacture or sell products in the State of California to disclose their efforts, if any, to provide information regarding their efforts to eradicate slavery and human trafficking in their direct supply chains. The law was designed to increase consumers’ knowledge about products they buy and the companies they choose to support.

Tesoro Corporation, its subsidiaries and affiliates (“Tesoro”) are committed to complying with the law wherever we operate and conducting all business activities in accordance with the highest ethical standards. We expect the same of the parties with which we do business. Our ethical standard is reflected in our Code of Business Conduct, “Doing the Right Thing” (“Code”), which outlines our expectations of ethical conduct and compliance with all laws from our employees and others who work for and represent Tesoro.

In addition to receiving our Code, employees take annual ethics and compliance training to certify their adherence with its standards, and/or disclose any exceptions. Tesoro maintains a 24/7 Business Conduct helpline where employees and contractors can anonymously submit any concerns of possible ethics and compliance violations, including slavery and human trafficking. Every submission is reviewed and handled accordingly. Any employee or contractor who is found to have violated the Code is subject to disciplinary action, up to and including termination of employment or contracts, and referral to appropriate legal authorities.

To ensure that our supply chain reflects our commitment to compliance and ethics standards, our corporate business practice provides that Tesoro’s purchasing decisions with suppliers are based on integrity. Tesoro expects its suppliers to comply with legal requirements and operate consistently with the principles of our Code when working on our behalf. Accordingly, we consider these rights issues when we assess potential suppliers. While Tesoro does not have a formal verification program, we do perform periodic audits of suppliers to evaluate and address issues relating to compliance with regulations and Tesoro’s policies, processes and procedures.
