NEW YORK, Sept. 24, 2013 /PRNewswire/ -- Pomerantz Grossman Hufford Dahlstrom & Gross LLP is investigating claims on behalf of investors of Eastern Insurance Holdings, Inc. ("Eastern" or the "Company") (NASDAQ: EIHI) (ISIN: US2765341043) (CUSIP: 276534104) concerning the proposed acquisition of Eastern by ProAssurance Corporation in a transaction valued at approximately $205 million, and is expected to close by January 1, 2014.

The investigation concerns whether the Eastern directors are breaching their fiduciary duties by failing to adequately shop the Company and maximize shareholder value.  Under the terms of the agreement, Eastern shareholders will receive $24.50 per share in cash for each share of Eastern common stock.  However, the Price to Revenue and Book Value multiples are below the average of comparable transactions, and synergies may not be fully reflected in offered price.

Eastern shareholders seeking more information about this acquisition are advised to contact Robert Willoughby at rswilloughby@pomlaw.com or 212-661-1100 or 888-476-6529, ext. 237.

The firm is also investigating actions on behalf of shareholders for the following companies:  Official Payments Holdings, Inc.
