"Date filed" indicates the date on which the company announced that it had filed a preliminary prospectus with the Securities and Exchange Commission for its offering. It is not necessarily the same date as that which is printed on the preliminary prospectus itself.
In completed offerings, the number of shares sold includes the overallotment (in full or in part) if that option has been exercised by the time this publication goes to press.
Shares outstanding refers to the number of shares outstanding after the public offering. In the case of those offerings which are still pending, it assumes that the number of shares sold in the offering will be equal to the number intended for sale as per the prospectus.
@ Values are estimated from the low-end range for IPOs.
