Escalator Advertising is likely to go into liquidation today, with creditors owed nearly $5 million.

The company is already in voluntary administration and receivership.

Escalator Advertising, which used to have its shares traded on the Unlisted exchange, has patents registered in 50 countries for its business idea: converting escalator steps to enable them to display advertising.

It went into voluntary administration last month, after Unlisted suspended its shares because the company had not paid its listing fees to the exchange.
