Weiss & Lurie, a national class action and shareholder rights law firm with offices in New York City and Los Angeles, is investigating possible breaches of fiduciary duty and other violations of law by the Board of Directors of Ameron International Corporation (NYSE:AMN), arising from its proposed acquisition by National Oilwell Varco, Inc. (NYSE:NOV).

Under the acquisition agreement, Ameron shareholders will receive $85 per share. The acquisition is expected close as early as the 4 th quarter of 2011.

Weiss & Lurie is investigating whether Ameron’s Board acted in the best interests of shareholders in approving the acquisition and whether the Board properly sought to maximize shareholder value. Before the deal was announced, at least one analyst had set a price target of $90 for Ameron. Moreover, Ameron stock traded above the acquisition price of $85 per share as recently as December 2010.
