According to CNOOC 20-F Filings, the company cites in its risk section the potential for U.S. sanctions related to its affiliates’ operations in Iran and Sudan. In particular, one of the company’s noncontrolled affiliates continued to provide certain drilling and other related services in Iran. In 2011, CalSTRS staff met with executives of the company in its offices in Beijing. The company confirmed its parent may have ties to Iran, but it does not, and will not, seek business in Iran as the company has and is looking to purchase more assets in the United States. CNOOC is listed on the December 31, 2018 CalSTRs Portfolio of companies identified as possibly having ties to Iran and from which CalSTRs has divested from and restricted in 2018. While CNOOC does not appear to have direct ties to Iran, CalSTRS is uncomfortable with its parent company’s relations to the country. In 2012, CalSTRS divested holdings of CNOOC and designated the company as “Divested and Restricted.” CalSTRS has maintained the “Divested and Restricted” designation in 2018.
