Unitholders and shareholders of LINN Energy LLC, LinnCo LLC and Berry Petroleum Co. have approved the companies’ merger and related transactions on Monday, setting the deal on course for closure as it passed its final hurdle at the U.S. Securities and Exchange Commission last month (see Daily GPI, Feb. 22). The deal is said to be the first-ever acquisition of a C-corporation by an upstream limited liability company or master limited partnership. Linn Energy last month raised its offer for Berry by $600 million, reinvigorating the mega-deal (see Daily GPI, Nov. 4).
