Over the course of the 1990s, Enron made a few changes to its business plan that greatly improved the perceived profitability of the company. First, Enron invested heavily in overseas assets, specifically energy. Another major shift was the gradual transition of focus from a producer of energy to a company that acted more like an investment firm and sometimes a hedge fund, making profits off the margins of the products it traded. These products were traded through the Gas Bank concept, now called the Enron Finance Corp. headed by Skilling.
