Which of the following statements is most correct? 1) Whenever a publicly owned firm decides to issue new common stock, it must register the stock with the SEC, and prospective stockholders must be given a copy of the prospectus. The SEC must approve the prospectus, and one key aspect of this approval is that the SEC must agree that the price at which the shares are to be offered is fair to investors. 2) Once a company "goes public," it must file periodic statements with the SEC. These periodic statements are called prospectuses, or, sometimes, "red herring" prospectuses. 3) Large companies such as IBM and Exxon are exempt from SEC listing requirements, but small companies (assets below $10 million) are not. Hence, small companies have listed stock, while large companies have unlisted stock. 4) In the United States, most new stock issues are sold through the commercial banks. 5) All of the above statements are false
