June 18 (Reuters) - U.S. agricultural company Ceres Global Ag Corp said on Friday some of its current and former employees had received subpoenas from the U.S. Department of Justice for paperwork related to Oat market trades from 2016 to 2019, and some other activities.

The company said it had also received a voluntary document request from the US Commodities Futures Trading Commission seeking similar information.

Ceres said it has cooperated and will continue to cooperate with both investigations. (Reporting by Shariq Khan in Bengaluru; Editing by Vinay Dwivedi)
