The 4M technology group, which makes compact disc machinery, is facing a deep financial crisis. Its share price at the Zurich stock exchange fell by 53 per cent to SFr6.50 ($3.84) at the close of trading on Friday, after a two-day suspension.
The company, based at Yverdon in canton Vaud, had asked for the suspension because long negotiations with the banks and the search for new investors to secure financing had not succeeded.
In a statement on Friday, the company said that its board of directors would meet again on Monday to decide on "appropriate measures". A statement is expected to be released on Tuesday, after the end of trading on the stock exchange.
4M Technologies (Multi Media Masters and Machinery) plunged deep into the red last year with a loss of SFr72.5 million, after making a profit of SFr10.5 million the year before.
