Macquarie may be a buyer of MIG

Macquarie Group is evaluating the merit of buying up the 82 per cent of shares in Macquarie Infrastructure Group that it does not currently own, the Financial Review reported in its Street Talk column. Macquarie Group is the manager of MIG, while MIG was the group's first significant satellite managed fund, established more than a decade ago.

The concept may seem a stretch given the market's valuation of MIG at around $3 billion. Macquarie Group, by contrast, sold $1.2 billion in new shares over the last month.

MIG is otherwise looking to sell toll road assets and pay down debt.
