The documents relate to the Barr, Switzerland-based company’s business in Nigeria, the Democratic Republic of Congo and Venezuela from 2007 to the present, the report said.
Glencore said it is reviewing the subpoena and will provide further information as appropriate.
Glencore’s mining operations in the Democratic Republic of Congo have been the subject of scrutiny by foreign governments and corruption watchdogs. But its oil operations in Venezuela and Nigeria haven’t surfaced before as a subject of interest by government officials.
Glencore is one of the world’s largest diversified mining companies and is also among the world’s largest traders of commodities, including grain. It employs 146,000 people in more than 50 countries.
Following the announcement that it was being subpoenaed, Glenore shares fell by as much as 13% but rebounded to just 5% down by late morning.
The Swiss-based company has been in the news in recent months for its reported interest in purchasing U.S. agribusiness giant, Bunge Ltd.
