Leading Australian investment bank Macquarie is restructuring to create a holding company, a move it says will free its non-banking businesses from regulations which hinder capital raising. Macquarie shareholders will be asked to vote on the plan on 25 October following approval this week from regulator the Australian Prudential Regulation Authority. Investors will exchange shares in Macquarie Bank for Macquarie Group scrip. The market liked the announcement on Monday, helping the shares - which have lost a third of their value in recent weeks - rebound 7.2 per cent.
