Airline Go First, which filed for bankruptcy on Tuesday, owes financial creditors $798 million, its bankruptcy filing showed.
As of April 30, Go First Air had not defaulted on any of these dues, it said in the filing, which was seen by Reuters.
"However, considering the present financial situation of the corporate applicant, defaults to financial creditors would be imminent," the filing said.
Lenders were not aware of the airline's plans to file for voluntary insolvency and will meet soon to take stock of the situation, said two people familiar with the matter. They spoke on condition of anonymity as they are not allowed to speak to the media.
The filing lists Central Bank of India, Bank of Baroda, IDBI Bank, Axis Bank and Deutsche Bank among Go First's financial creditors.
Deutsche Bank declined to comment. Emails sent to the other banks were not immediately answered.
The airline's total liabilities to all creditors stand at 114.63 billion rupees, the filing shows. This includes dues to banks, financial institutions, vendors and aircraft lessors.
"Currently, the assets of the company are not sufficient to meet its liabilities," the airline said in the filing.
The company has defaulted on payments to operational creditors, including 12.02 billion rupees to vendors and 26.60 billion rupees to aircraft lessors.
It has received notices from lessors for termination of aircraft lease agreements and some have started actions against the company to ground or repossess aircraft, the filing said.
Six lessors have also invoked letters of credit issued to them by lenders, it said.
