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.

Note: 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 US Index eligibility requirements. Additionally, the IPO must meet the following criteria on the rank day for the quarterly additions: (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.
