Now what

United Microelectronics also responded to a media report last week from United Daily News that speculated that the company had received wafer orders from large consumer electronics manufacturers and that additional production capacity was difficult to secure.

"UMC has a clear company policy about not commenting on customers or their order status and has not disclosed any of the business or operation details mentioned in the article," the company wrote in the filing. "The report is based on the speculation of the journalist."

UMC is scheduled to report second-quarter results on Wednesday.
