问答题Practice 3 Equity securities are known as shares (or stock) in a corporation. Stockholders are considered owners of the corporation. The Articles of Incorporation must state the number of shares and the characteristics of the stock. To issue stock is actually to offer shares of stock for sale. The corporation’s Board of Directors controls when and to whom the corporation’s shares are offered and sold. Outstanding shares—Outstanding shares are shares already issued and purchased by the shareholder or stockholder. Par value—Par value is an arbitrary value assigned to each share in the Articles of Incorporation but does not necessarily reflect the true market value of the stock. Shares may not be issued and sold by the corporation for less than their par value therefore it is sometimes advisable not to state any par value at all or state a par value lower than the estimated market price. No par value allows the Board of Directors to decide each time shares are issued what the price per share will be. In a very large corporation where the stock is publicly traded at a public exchange, such as the New York Stock Exchange, the public demand for the stock of the corporation rather than the Board of Directors determines the selling price of the stock. Capital account—The capital account of a corporation is an entry in the books of the corporation and is determined by multiplying the par or stated value of the corporation’s stock by the number of shares outstanding. For example, if the corporation had sold 1,000 shares of stock which had $10 par value, the capital account would be $10,000.
