FGV Holdings, the world's largest crude palm oil producer, changed its top management amid investigations into its business practices last year.

Its former chief executive officer stepped down in September following his suspension in the wake of an internal investigation. The previous chief financial officer resigned in October.

FGV began its internal investigation last year following "adverse findings" from an earlier probe into its investments.

The company has been plagued by allegations of poor management, and has seen its share price decline by more than 80 percent since its listing in 2012.
