Sojitz Holdings Corp. said Wednesday it expects to incur about 16 billion yen in appraisal losses possibly caused by a serious violation of an in-house rule on commodity futures transactions at trading house Sojitz Corp.

The company said it will set up an "investigation committee" and invite an outside lawyer to clear up the matter.

The company said it will specify the amount lost as soon as possible and dispose of all the losses within this fiscal year, which ends March 31.
