Index IPO additions

Initial public offerings (IPOs) are added to the Russell Indexes on a quarterly basis. Adding IPOs, in addition to the annual Reconstitution of our indexes, leads to an enhanced market representation without significant turnover.

Russell US Indexes IPO calendar

* If a date falls on a holiday the previous business day is used.
** After the close on the third Friday.
***Once IPO additions have been announced, an IPO may be added to the index prior to the previously announced schedule, if a corporate action has deemed this to be appropriate and notice can be provided (e.g. an index member automatically receives shares via a stock distribution into a projected IPO add).In order to be added during a quarter outside of reconstitution, an IPO must meet all Russell U.S. Index eligibility requirements. Additionally, the IPO must meet the following criteria on the final trading day of the month prior to quarter-end: (1) it is priced and traded; and (2) it ranks larger in total market capitalization than the market-adjusted smallest company in the Russell 3000E Index as of the latest June reconstitution. See Appendix F for calculations.
