Trading in Bombardier shares was halted on the Toronto Stock Exchange late Thursday afternoon while the company revealed a plan to dilute its shareholders and sell up to 390 million new shares in the company.


The Montreal-based aerospace company announced what's known as a bought deal as the TSX was about to close. Four underwriters including CIBC, Citibank, National Bank and UBS have agreed to sell up to 390 million subscription receipts to their clients, which can be exchanged for B shares in the company.


Those subscription receipts would be priced at $2.21 per share. Before trading was halted, Bombardier shares were trading at $2.46 on the TSX.


The deal could raise as much as $863 million for the company, which pledged last week to shore up its balance sheet.
