A coach operator has filed a lawsuit asking the High Court to wind up ATV over unpaid bills totaling HK$900,000.
A spokeswoman for Hop Chung Tourist Car Company said the firm had for the past 20 years provided the broadcaster with a shuttle bus, transport for shoots and public relations bus services.
Both parties did not renew the contract when it expired on April 30.
The company said it had urged ATV to settle the bill but the station only made a partial payment. The company's stockholders had then decided to take the matter to court.
The spokeswoman, named Lee, said the firm is merely running a "small business" and that on one occasion ATV owed it more than HK$1 million.
ATV executive director James Shing Pan-yu said he would not comment on the lawsuit but assured reporters the TV station is financially sound.
"ATV has no financial problems and its operation remains normal," he said.
Up until 3.30pm yesterday, ATV said it had not received any legal documents. A spokesman for ATV said it is a pity that the coach company had decided to go to court but the station will seek legal channels to resolve the dispute.
In 2011, a company controlled by Taiwanese tycoon Tsai Eng-meng - who had invested in the TV station - filed a lawsuit seeking to recover his investment of HK$23 million. ATV later said it had settled the payment and the request for liquidation was canceled.
The broadcaster, long in the shadow of larger rival TVB, has had financial and other problems over the years.
