Virgin Australia Holdings Ltd. stock was suspended in Sydney as discussions over a potential financial restructuring for the airline continue.

The shares, already halted from trading, will be suspended for as long as seven days so talks centered on financial help and alternative structures can go on, Virgin Australia said in a statement Thursday.

“These discussions have continued over the last two days, including discussions which remain confidential and are incomplete,” Virgin Australia said in its statement. “The company is not presently in a position to make an announcement to the market with respect to these matters.”

The airline, which has stopped virtually all services during the coronavirus outbreak, has been exploring options for securing capital for weeks. It has asked the government for a $1.4 billion ($883 million) loan to weather the crisis.

Virgin Australia is almost entirely owned by foreign airlines. Singapore Airlines Ltd., Etihad Airways, HNA Group Co. and Nanshan Group Co. each own about 20%. Australian Treasurer Josh Frydenberg said Wednesday the airline’s “first point of call” should be its shareholders.
