If an interest in a cooperative is currently registered with the Securities and Exchange Commission of the United States, a declarant satisfies all requirements relating to the preparation of a public offering statement of this chapter if he delivers to the purchaser and files with the agency a copy of the public offering statement filed with the Securities and Exchange Commission. A cooperative interest is not a security under the provisions of the Securities Act, §§ 13.1-501 through 13.1-527.3.
