Tacoma, WA — April 26, 2006 — Russell Investment Group plans to launch the Russell Microcap™ Growth Index and Russell Microcap™ Value Index at the end of June. These indexes will serve as style counterparts to the Russell Microcap™ Index, which was introduced last June.

"Our research confirms there is a real need for truly representative style benchmarks for microcap managers," said Steve Swartley, senior manager research analyst. "The performance of microcap stocks in the past three years alone shows a distinct difference between growth and value stocks in this dynamic market segment. This performance gap is important as most microcap managers have a style bias toward growth or value."

The Russell Microcap Index measures the microcap segment of the U.S. equity market, which as of the last reconstitution included stocks ranging from $54.8 million to $539.5 million. The median market capitalization for this index, which represents about 3% of the equity market, is $182.6 million.

Those stocks in the Russell Microcap with higher price-to-book ratios and higher forecasted growth values will be included in the Russell Microcap Growth Index, while those stocks with lower price-to-book ratios and lower forecasted growth values will comprise the Russell Microcap Value Index. For more background on Russell's style methodology, please see the in-depth description posted on www.russell.com/US/Indexes/US/methodology.asp.

With the addition of these two indexes, Russell's suite of U.S. indexes will increase to 26. Russell employs its indexes to evaluate investment managers for multi-manager funds and other investment services. More than $3.8 trillion in assets are benchmarked to them.
