Toshiba warns it may not survive financial problems

Toshiba has filed its delayed financial results, warning that the company's survival is at risk.
    
The electronics-to-construction giant reported a loss of $4.8 billion for April to December.
    
However, the results have not been approved by the firm's auditors.
    
These latest financial results have already been delayed twice and raise the possibility that Toshiba could be delisted from the Tokyo Stock Exchange.
