EITI Principles of Transparency
Extractive Industries Transparency Initiative/EITI provides a guideline for accountability and transparency in the extractive industries sector. Countries need to perform a validation process and meet all third-party validation indicators within a period of 2 years. There are currently 39 abiding global extractive industry companies. FCX (and PTFI) supports and actively participates in the EITI process. Other members include international NGOs and industry associations, including ICMM. EITI requires verification and full publication of payments made to the government, as well as the benefits derived from the extractive industry.
