Struggling Toshiba Corp. dodged delisting Thursday by submitting its annual business report for 2016 just before the deadline, accompanied by a shaky sign-off from its auditor.

But other delisting scenarios still loom for the Tokyo-based conglomerate, which must eliminate its massive negative net worth by end of March.

Normally, companies with an April-March business year must file their annual reports with the Kanto Local Finance Bureau by June 30, but Toshiba postponed submission because its auditor needed more time to scrutinize figures related to Toshiba's troubled U.S. nuclear unit Westinghouse Electric Co.
