In finance, private equity is an asset class consisting of equity securities in operating companies that are not publicly traded on a stock exchange.
A private equity investment will generally be made by a private equity firm, a venture capital firm or an angel investor. Each of these categories of investor has its own set of goals, preferences and investment strategies; each however providing working capital to a target company to nurture expansion, new product development, or restructuring of the company’s operations, management, or ownership.
Bloomberg BusinessWeek has called private equity a rebranding of leveraged buyout firms after the 1980s. Among the most common investment strategies in private equity are: leveraged buyouts, venture capital, growth capital, distressed investments and mezzanine capital. In a typical leveraged buyout transaction, a private equity firm buys majority control of an existing or mature firm. This is distinct from a venture capital or growth capital investment, in which the investors (typically venture capital firms or angel investors) invest in young or emerging companies, and rarely obtain majority control.

In 1942, his father was elected to the first of four terms in the United States Congress, and after moving with his family to Washington, D.C., Warren finished elementary school, attended Alice Deal Junior High School, and graduated from Woodrow Wilson High School in 1947, where his senior yearbook picture reads: "likes math; a future stock broker."
