Toyota Motor Corporation said in a regulatory filing Thursday it has “reported possible anti-bribery violations related to a Thai subsidiary” to U.S. enforcement agencies.

Toyota said it alerted the Securities and Exchange Commission and the Department of Justice about the potential violations in April 2020 and is “cooperating with their investigations.”

“The investigations could result in the imposition of civil or criminal penalties, fines or other sanctions, or litigation by the DOJ or the SEC,” Toyota said.

The company did not provide any further details.
