Earlier, Jet Airways chairman Naresh Goyal, his wife Anita Goyal and Etihad Airways nominee Kevin Knight stepped down from the board to allow for the lenders to take over in a bid to revive the airline by bringing in new investors. Lenders led by State Bank of India (SBI) are now initiating a bidding process for the sale of shares to a new investor or promoter. The process is expected to be completed in the June quarter. The board has already approved the issue of 11.4 crore equity shares of the airline to lenders upon conversion of outstanding debt, which would be subject to relevant approvals and laws. As a result stake of the Goyals will come down to less than half the existing 50.1 per cent. For the last three months, the airline has not paid salaries to its employees including pilots, and other senior executives.
