Some Rockefeller family members are to host a news conference in New York on April 30 “urging a major change in corporate governance in the form of an independent chairman of the board and a bigger leadership role for the oil company’s board of directors,” reports a marketing agency. “More than a dozen Rockefeller family members have sponsored four proxy resolutions this year, raising a range of concerns about how the management of ExxonMobil under Rex Tillerson—who is both the CEO and chairman—is failing to address the future of energy and related industry hurdles. “The Rockefeller family members are the longest continuous shareholders of ExxonMobil Corp. After years of working behind the scenes to encourage Exxon’s management to approach its industry challenges in new ways, members of the Rockefeller family will publicly explain the concerns held by multiple generations of their family.” Speakers will include Neva Rockefeller Goodwin, economist and great-granddaughter of John D. Rockefeller; Peter O'Neill, head of the Rockefeller family committee dealing with ExxonMobil, and great-great-grandson of John D. Rockefeller; and Stephen B. Heintz, president, Rockefeller Brothers Fund. Also speaking will be Connecticut’s state treasurer, Denise L. Nappier. An audio recording will be online after 3 p.m. CDT on April 30 at http://www.hastingsgroup.com/rockefellerfamily. –Nissa Darbonne, Executive Editor, Oil and Gas Investor, A&D Watch, Oil and Gas Investor This Week, www.OilandGasInvestor.com; ndarbonne@hartenergy.com
