Recently, Goldman Sachs announced its partnership with Riverstone Holdings. The deal is approximately $ 500 million with a 12% percent share in the investment of energy. The Walls Street Journal stated that the values of the Riverstone transaction total up to over $4 billion. The two companies are geographically located in New York City. However, Riverstone has another office in the United States of America. According to the two organizations, the partnership will unite the founders of Riverstone and Goldman Sachs. This is because they had worked together in the initial stages of their careers. In 2000, David Leuschen had been employed in New York with Pierre Lapeyre. The two have a past working experience in M&A energy firm. They were in charge for initiating stock sales deals.
