[ by Howard Haykin ] After the market closes tomorrow, Friday, 6/22, the Russell Investment Group will reconstitute certain of its indices, including the Russell 3000 Index and the Russell Microcap Index. This being a notice published by NYSE-Regulation, it notes that the reconstitution may significantly affect the volume of trading on the NYSE and NYSE MKT - (collectively, the “Exchange”) - particularly as we near the close of trading on Friday, 6/22. The Information Memorandum reminds members and member organizations of certain Exchange Rules and policies regarding:

• entry and cancellation of MOC/LOC and Closing Offset (“CO”) orders;
• publication of on‐the‐close imbalances; and,
• printing the closing transaction.

This IM also provides guidance on possible system interruption scenarios and the operation of certain Exchange Rules and policies in the event that such a scenario occurs. Note: While Reconstitution of certain Russell Indexes will take effect after the close of U.S. equity markets on Friday, 6/22, it should be noted that two weeks earlier, on 6/8/12, a preliminary list of additions and deletions to those indices being changed was published by the Russell Investment Group. The Exchange expects that during the trading day on June 22, and especially at or near the Close, significant trading volume associated with portfolio rebalancing will be initiated based upon those lists.  Based on the preliminary lists, 122 NYSE‐listed stocks and 68 NYSE MKT‐listed stocks will be added to or deleted from the indices, though more stocks could be impacted by the reconstitution.
