NEW YORK, 2011-06-25 02:47 CEST (GLOBE NEWSWIRE) —
The following press release, issued earlier, now includes additional
information in the second paragraph:

The NASDAQ OMX Group, Inc. (Nasdaq:NDAQ) today announced the NASDAQ Closing
Cross was used for the eighth consecutive year to reconfigure the entire family
of U.S. Russell indexes during their annual reconstitution. In 1.1 seconds the
NASDAQ Closing Cross executed approximately 750.8 million shares representing
$10.6 billion across some 2,298 NASDAQ-listed stocks.

To see the top 10 crosses in terms of share volume, please visit
http://media.globenewswire.com/cache/6948/file/10736.pdf. NASDAQ official
closing prices (NOCPs) determined by the NASDAQ Closing Cross are widely used
throughout the industry, including by Russell Investments, Standard&Poor–s,
Dow Jones, and mutual funds across the country.

–The NASDAQ Closing Cross is a price discovery facility which has become an
industry standard for index providers, mutual fund managers and the investing
public who seek accurate closing prices in microseconds,– said Eric Noll,
Executive Vice President of Transaction Services, NASDAQ OMX. –Although this
year we experienced a lower number of shares in the rebalance, we continued to
witness the NASDAQ Closing Cross generate accurate closing prices thanks to our
proven INET technology platform.–

The Closing Cross brings together the buy and sell interest in specific NASDAQ,
NYSE and NYSE Amex stocks and executes all shares for each stock at a single
price, one that reflects the true supply and demand for these securities. All
nationally-listed securities are eligible for the NASDAQ Closing Cross.

The Russell U.S. Indexes include only common stocks incorporated in the U.S.,
its territories, and certain countries or regions offering U.S. companies
operational, tax, political or other financial benefits. All Russell U.S.
indexes are subsets of the Russell 3000(tm) Index, which represents approximately
98% of the U.S. equity market. Russell U.S. Indexes allow investors to track
current and historical market performance by specific market segment (large
cap/small cap) or investment style (growth/value/defensive/dynamic). Today,
more than $3.9 trillion in assets are benchmarked to the Russell Indexes.

Russell reconstitution day is usually one of the most highly anticipated and
heaviest trading days in the U.S. equity market as asset managers seek to
reconfigure their portfolios to reflect the composition of Russell–s U.S.
indexes. The index reconstitution process was completed today and the newly
reconstituted index membership will take effect before markets open on Monday,
June 27, 2011.
