Corporate Governance

Integrity is key to Ternium’s long term success. The
Company has appointed a business conduct compliance
officer, who reports to the CEO.

Ternium has mandatory training programs on the Company’s
Policy on Business Conduct and has adopted several policies,
codes and procedures to ensure transparency and ethical
behavior. 

In addition, the Company has put in place a Compliance
Line to report violations to its code of conduct and
principles.

Our compliance department oversees SOX certifications

directors has an audit committee solely composed of
independent directors.

The internal audit department, which meets organizational
independence and objectivity standards, reports to the
