Failure to comply with the Code of Conduct, policies, regulations, guidelines, principles, internal procedures, or current legislation can have serious consequences for the parties involved, the Company, its Management, and society in general.

When misconducts have been proved, measures shall be applied according to the seriousness of the acts, ranging from verbal or written warning, suspension, or more serious sanctions, such as: dismissal for justifiable cause; termination of employment contracts, services contracts or partnership agreements, among others; compensation for damages, as well as the notification of the facts to competent authorities, in which the responsible parties shall be liable to administrative, civil or criminal proceedings, as appropriate and based on the seriousness of the misconduct.
