A preliminary prospectus that intentionally lacks certain facts about the initial public offering (IPO). This involves the filing of a registration statement without including information such as lead underwriter, offering size, offering price, etc. An issuer might resort to a quiet filing if it wants to proceed with the offering process while it works on sorting out some unfinished issues. Although issues are normally permitted to omit such information from the preliminary prospectus, the prospectus should not be distributed to the market.
