Weil Gotshal & Manges has landed roles on two major US deals in a week, worth more than $45bn (£22.7bn), acting on the management buy-out of Kinder Morgan and the acquisition of Archstone-Smith by Tishman Speyer.

Weil Gotshal is advising Kinder Morgan management on the privatisation of the energy transportation and storage company, which is valued at approximately $23bn (£11.6bn).

Goldman Sachs Capital Partners, American International Group, the Carlyle Group and Riverstone Holdings are backing the deal, which will see Kinder Morgan de-list from the New York Stock Exchange. The group is among the largest of its kind in North America, owning a stake in or operating 41,000 miles of pipelines.
