Whistleblowing
The Company is firmly committed to sustainability, which includes maintaining a transparent and accountable process for addressing grievances related to corporate conduct. To ensure that any complaints related to corporate behavior are addressed properly, the Company has established a comprehensive grievance mechanism. This system not only upholds our integrity but also fosters a culture of ethical behavior across all levels of the organization.
• Investigation Process: Upon receiving a complaint or information that meets the evidential threshold necessary to warrant further action, a dedicated investigation team is formed. This team conducts a thorough investigation following the corporate fraud management manual.
• Informing the Complainant: Once the investigation is completed, the complainant will be informed of the outcomes. This communication is carried out through designated channels to ensure clarity and confidentiality.
• Taking Action: If an allegation is substantiated, the Company will take appropriate action depending on the severity and nature of the misconduct. Actions may range from internal disciplinary measures to legal proceedings, ensuring that misconduct is addressed decisively and in alignment with corporate values.
• Reporting to Governance Bodies: The outcomes of all investigations, along with subsequent actions, are reported to the Corporate Governance and Nomination Committee quarterly. Additionally, an annual report is presented to the Board of Directors, summarizing the overall effectiveness of the grievance mechanism and any significant cases or trends.
