Along with its affiliate Brookfield Infrastructure Partners, the global asset manager will pay $A295 million for the DBCT stake and for 100% of UK port operator PD Ports.
In addition, the two Brookfield companies will spend between $A625 million and $713 million in BBI stapled securities for a 35-40% interest in the Australian company.
Brookfield will also pay off £100 million ($A177 million) of debt owed by PD Ports.
Both Brookfield companies plan to raise further equity to raise funds for the deal and will seek approval from their shareholders.
Aside from these investments, BBI’s $A1.5 billion recapitalisation program includes a $625 million placement to institutional investors and a $250 million security purchase plan, with Brookfield subunderwriting up to $87.5 million of this issue.
BBI said if the recapitalisation plan was not approved, if no alternative proposal emerged or if its banks did not agree to a debt moratorium, it might have to be placed into administration.
DBCT is one of the largest coal export terminals in the world and serves 10 northern Bowen Basin mines.
Last year 83.9 million tonnes of coal were exported from DBCT and the neighbouring Hay Point Coal Terminal, which is wholly owned by BHP Billiton Mitsubishi Alliance.
Administrator Deloitte saw the March collapse of investment bank Babcock & Brown as similar to the failure of insurance company HIH in 2001.
The bank was brought down by over $3 billion of debt.
