Visteon Corporation will delay filing its first-quarter financial report for an independent review of certain North American purchases and possible improper conduct by a senior employee.

According to an Associated Press (AP) report, the company said the delay will not affect restructuring talks with Ford, Visteon's former parent company and its largest customer - since September, the companies have been discussing structural changes to their relationship that Visteon says are necessary to keep it competitive.

AP said that Visteon's audit committee recommended the independent accounting review after a review of errors related to freight and materials surcharges led to allegations of potential improper conduct by a former senior finance employee, who was responsible for the accounting oversight for North American purchasing.

The company reportedly said in April that it would record about $US31 million in charges related to prior periods but has now said that it does not yet know if these or any other adjustments will require restatements of earlier financial reports.

Visteon also said it is not sure how soon it will be able to file the first-quarter report, the Associated Press noted.
