Rigrodsky & Long, P.A. announces that it is investigating potential legal claims against the board of directors of Plains Exploration & Production Company (“PXP” or the “Company”) (NYSE: PXP) regarding possible breaches of fiduciary duties and other violations of law related to the Company’s entry into an agreement to be acquired by Freeport-McMoRan Copper & Gold Inc. (“FCX”) (NYSE: FCX) in a transaction valued at approximately $6.9 billion. Click here to learn more: http://www.rigrodskylong.com/investigations/plains-exploration-production-company-pxp. Under the terms of the proposal, public shareholders of PXP will receive $25.00 in cash and 0.6531 shares of FCX for each share of PXP they own. Based on FCX’s closing stock price of $38.28 on December 4, 2012, PXP shareholders would have received consideration valued at approximately $50.00 per share. The investigation concerns whether PXP’s board of directors failed to adequately shop the Company and obtain the best possible value for PXP’s shareholders before entering into an agreement with FCX. According to Yahoo! Finance, at least one analyst has set a price target for PXP stock at $78.00 per share.
