Dec.06 -- In this week's "Commodity in Chief," Bloomberg's Alix Steel talks with Karl Peterson, managing partner at the TPG Pace Group. They discuss the increased role of SPACs (Special Purpose Acquisition Company) in the energy industry, the "rockstar" CEOs of SPACs, and Magnolia Growth. Incorporated for the sole purpose of an acquisition, SPACs raise capital by listing shares on a stock exchange ahead of time. They’re often led by a well-known industry leader or dealmaker who can garner the trust of would-be investors.
