Even if the P3 Network were not approved, Macquarie Equities Research estimates that the world's top container shipping line would still raise its ROIC from eight per cent at present to 12 per cent.
"If the P3 is approved, our analysis suggests the average vessel size used by Maersk Line on Asia-Europe would increase from 9,300 TEU to 14,200 TEU by end-2015," Macquarie said in a research note.
