Russell Global Index is absorbing 31 initial public offerings for the fourth quarter, effective Monday, Dec. 19.

Eleven of these additions are also being made to the Russell 2000 Index. Fifteen of the IPOs are also becoming part of the Russell ex-U.S. Index—12 of which are in Asia-Pacific, eight in emerging markets and four becoming part of the Russell Greater China Index.

In the U.S., 16 of the IPOs are also being added to the U.S. broad market Russell 3000 Index. This is down from the 25 IPOs that were added in the U.S. in the third quarter.

The total 31 IPOs being added to the global index in the fourth quarter is down significantly from the 90 IPOs added in the third quarter of 2011.

Three notable IPOs being included, Russell said, are Groupon, Angie’s List and Manning & Napier.

“The quarterly addition of eligible IPOs worldwide is a significant component of the Russell Index methodology, allowing for enhanced market representation without significant turnover,” said Rolf Agather, global managing director of index research and innovation at Russell Investments.

Stephen Wood, Russell’s chief markets strategist, added: “These IPO data show that volatility in market conditions continues to impact assets both in the U.S. and around the globe.”
