TOKYO (Reuters) - Toshiba Corp 6502.T on Thursday denied a media report that the company was told by its auditor that it would not provide an opinion, or an endorsement, for its annual report.

Toshiba has been unable to file an audited financial report for the year ended March. It has been at odds with auditor PricewaterhouseCoopers Aarata (PwC) since a surprise writedown at its now-bankrupt Westinghouse nuclear unit.

Toshiba’s shares fell as much as 5.8 percent after the Asahi newspaper report. They were down 3.9 percent in mid-morning trade.

The company said in a statement it would continue working with its auditor to meet an Aug. 10 filing deadline.
