Reporting Unethical Conduct

Marathon Petroleum Corporation (MPC) employees have a duty to immediately report suspected illegal or unethical conduct connected with the business of MPC or its affiliates. The following summarizes MPC’s Reporting of Illegal or Unethical Conduct Policy:

  • Any employee who observes any activity which he or she believes is illegal or unethical has a duty to report it. The following resources are available for reporting: a supervisor; any member of management; the Internal Audit, Law, Human Resources, Health, Environment, Safety and Security and Business Integrity and Compliance organizations, and the company’s Integrity Helpline. Current information as to how and where employees may make such reports is published by MPC on a regular basis by such means as the corporate intranet and company bulletin boards.
  • If a supervisor receives such a report, the supervisor must immediately advise the Internal Audit, Human Resources, Health, Environment, Safety and Security, Law or Business Integrity and Compliance organizations of such report.
  • Reports of misconduct received by Business Integrity and Compliance are referred to the Internal Audit, Law, Human Resources, and Health, Environment, Safety and Security organizations, as appropriate, for investigation. All investigations received by or referred to these organizations will be performed promptly, and necessary and appropriate action will be taken.
  • If desired by a reporting employee, MPC will take reasonable steps to treat their identity as strictly confidential, and will disclose their identity, or such facts as may reasonably be believed to lead to the discovery of their identity, only as necessary to comply with legal requirements and investigate the reported conduct.  Those investigating the reported misconduct and made aware of such reporter’s identity will be advised of the need for confidentiality. Individuals using MPC’s Integrity Helpline will be given the opportunity to remain anonymous.
  • No employee will be discharged, disciplined, or otherwise disadvantaged in his or her career or suffer any other form of reprisal as a result of having reported suspected illegal or unethical conduct. Filing a good faith report will never be a cause for disciplinary action.
