29 | Sustainability Report Highlights Ethics and integrity ExxonMobil strives to uphold high ethical standards at all times and in all aspects of our business. Our Standards of Business Conduct set the ethical conduct expectations for our corporation and majority-owned subsidiaries. Employees must annually confirm they have read and comply with the standards to ensure a consistent understanding. ExxonMobil requires all employees, officers, directors and those working on our behalf to comply with all applicable laws. ExxonMobil encourages employees and contractors to ask questions, voice concerns and report any alleged violations of company policies. In addition to our open-door communication procedures, we have several confidential mechanisms for reporting. Employees can submit concerns through a 24-hour phone hotline or a mailing address. We respect confidentiality, subject to legal requirements, and strictly prohibit retaliation against any employee for submitting concerns. A hotline steering committee reviews reports of suspected violations. The board audit committee, comprising four independent, non-employee directors, oversees accounting and internal control matters for the company, including compliance with legal and regulatory requirements. The board audit committee receives a quarterly report summarizing the steering committee’s findings, including any policy violations. Confirmed violations lead to disciplinary actions, up to and including termination. For more information on the board audit committee, please see the company’s annual proxy statement . ExxonMobil conducts regular internal audits and self-assessments to verify the effectiveness of our control systems and adherence to our Standards of Business Conduct. Our team of internal auditors annually reviews approximately one-third of the corporation’s activities and processes. Internal auditors have access to all operations, records, personnel and properties. We thoroughly investigate any suspected acts of noncompliance with the Standards of Business Conduct. Employees in relevant job functions receive in-person training on antitrust, anti-corruption, anti-boycott, trade sanctions and export controls soon after entering their positions, as well as every year thereafter. In 2019, nearly 24,000 employees and contractors participated in such training.
