This is a simplified optional registration form that may be used by companies that have been required to report under the '34 Act for a minimum of three years and have timely filed all required reports during the 12 calendar months and any portion of the month immediately preceding the filing of the registration statement. Unlike Form S-1, it permits incorporation by reference from the company's annual report to stockholders (or annual report on Form 10-K) and periodic reports. Delivery of these incorporated documents as well as the prospectus to investors may be required.
