Mitsui & Co. said Friday its in-house probe turned up fictitious transactions worth ¥51.8 billion in connection with exports to an Indonesian corporate group.
Three employees at the trading house's performance chemicals business unit are under investigation on suspicion that they were involved in the irregularities over five years through March.
The fake deals were limited to less than 0.1 percent of Mitsui's total sales on an annual basis so past earnings do not have to be corrected, the company said.
