UPDATE 1-Singapore's Pacific Shipping to raise $92.3 mln

(Adds that PIL to take up unsubscribed units)

SINGAPORE, Aug 11 (Reuters) - Singapore's Pacific Shipping Trust (PFST.SI) plans to raise up to $92.3 million via a preferential share sale to help fund the purchase of four vessels, the trust said on Monday.

Pacific Shipping Trust will issue 252.8 million new units by offering shareholders three new units for every four existing units. Pacific International Lines, the trust's major shareholder with about 35 percent, will subscribe for units not taken up by other investors.

The new units are priced at $0.365 each, marginally below the last traded price of $0.375.

Pacific Shipping said the proceeds will be used to fund the acquisitions of new vessels, as working capital, and for other corporate purposes.
