A holding company is a company or firm that owns other companies' outstanding stock. The term usually refers to a company that does not produce goods or services itself; rather, its purpose is to own shares of other companies to form a corporate group. Holding companies allow the reduction of risk for the owners and can allow the ownership and control of a number of different companies.
In the United States, 80% or more of stock, in voting and value, must be owned before tax consolidation benefits such as tax-free dividends can be claimed.[1] That is, if Company A owns 80% or more of the stock of Company B, Company A will not pay taxes on dividends paid by Company B to its stockholders, as the payment of dividends from B to A is essentially Company A switching cash from one of its pockets to another. Any other shareholders of Company B will pay the usual taxes on dividends, as they are legitimate and ordinary dividends to these stockholders.
Sometimes a company intended to be a pure holding company identifies itself as such by adding "Holdings" or "(Holdings)" to its name.
After the financial crisis of 2007–08, many U.S. investment banks converted to holding companies. According to the Federal Financial Institutions Examination Council's (FFIEC) website, JPMorgan Chase & Co., Bank of America Corp., Citigroup Inc., Wells Fargo & Co., and Goldman Sachs Groups, Inc. were the five largest bank holdings companies in the finance sector, as of 31 December 2013, based on total assets.[2]
Shares outstanding are all the shares of a corporation or financial asset that have been authorized, issued and purchased by investors and are held by them. They have rights and represent ownership in the corporation by the person that holds the shares. They are distinguished from treasury shares, which are shares held by the corporation itself and have no exercisable rights. Shares outstanding plus treasury shares together amount to the number of issued shares.
Shares outstanding can be calculated as either basic or fully diluted. The basic count is the current number of shares. Dividend distributions and voting in the general meeting of shareholders are calculated according to this number. The fully diluted shares outstanding count, on the other hand, includes diluting securities, such as warrants, capital notes or convertibles. If the company has any diluting securities, this indicates the potential future increased number of shares outstanding.
