Interactive Data to Calculate and NASDAQ OMX to Disseminate Indexes

NEW YORK and BEDFORD, Mass., April 1, 2009 (GLOBE NEWSWIRE) -- The NASDAQ OMX
Group, Inc.(sm) (Nasdaq:NDAQ) and Interactive Data Corporation (NYSE:IDC), a
leading provider of financial market data, analytics and related solutions,
today announced they have been selected by Wilshire Associates Incorporated to
support several of the indexes from the suite of Wilshire Indexes. 

Wilshire Associates -- a leading global independent investment consulting and
services firm -- has selected Interactive Data's Pricing and Reference Data
business to calculate the real-time values for selected indexes. NASDAQ OMX(sm)
was selected as disseminator of index values for these Wilshire Indexes through
NASDAQ OMX's Global Access solutions. Interactive Data will publish values for
the selected Wilshire Indexes in real-time to the NASDAQ OMX Global Index
Dissemination Service(sm) (GIDS(sm)). GIDS is designed to facilitate better
trading performance and portfolio valuation due to real-time dissemination of
index data. 

GIDS is a value-added product for firms that wish to receive the full
complement of NASDAQ OMX global index and ETF data. GIDS subscribers have lower
administrative and technology costs than firms that take the products
separately and it facilitates better trading performance and portfolio
valuation due to its frequent dissemination of index and ETF data. Interactive
Data's Basket Calculation Service(tm) utilizes real-time equity pricing data
from global exchanges to calculate real-time values for indices. 

"Our mandate as an index provider is to measure and describe the market in ways
that are meaningful and important to investment professionals worldwide," said
David Hall, senior managing director, Wilshire Associates and head of the
Wilshire Equity Analytics division of Wilshire Analytics. "We are confident
that Wilshire Indexes provide the best measure of equities markets spanning the
globe and that through our relationship with Interactive Data Corporation and
NASDAQ OMX, investors will quickly adopt them as their preferred index family." 

"We are pleased to be selected as the disseminator of index values for a
leading index provider like Wilshire," said Randall Hopkins, Senior Vice
President of Global Data Products, NASDAQ OMX. "By leveraging the capabilities
of NASDAQ OMX and Interactive Data, we can provide critical index information
to the market in a timely manner. We are also delighted to expand our
