The new amendment to Dorian's initial public offering prospectus comes as the LPG owner nears a marketing roadshow, will could begin as early as next week.

Dorian's new target is a maximum $150m worth of public shares -- down from an initial top goal of $287.41m stated in the first prospectus in March, then reduced to $175m on 1 April.

The private sale is an entirely new component in Dorian's listing efforts, and speculation is bound to flow as to the identity of the strategic investor.
