Iowa Peace Officers Retirement System Adds Dow Jones Wilshire 5000 Index to Its Equity Benchmarks

$300 Million Public Pension Fund Uses Dow Jones Wilshire Index Family to Monitor Portfolio Managers


NEW YORK, July 31, 2007 (PRIME NEWSWIRE) -- Dow Jones Indexes, a leading global index provider, and Wilshire Associates, a global leader in investment technology, investment consulting and investment management, announced today that Iowa Peace Officers Retirement System has adopted the Dow Jones Wilshire Index Family, including the Dow Jones Wilshire 5000(sm), to benchmark its equity investment portfolio.

The announcement comes after Iowa Peace Officers, a US$300 million system with oversight provided by the Treasurer of the State of Iowa, conducted a series of studies demonstrating the value of the Dow Jones Wilshire Indexes as an effective tool to monitor their domestic equity manager's process and performance.

Iowa State Treasurer Michael Fitzgerald said, "The Dow Jones Wilshire Indexes are an important benchmarking tool that helps us oversee our equity managers more effectively by providing the most accurate comparison of active and passive investment strategies."

About the Dow Jones Wilshire Index Family

The Dow Jones Wilshire 5000 is the primary domestic component of the Dow Jones Wilshire Global Total Market Index(sm) and a cornerstone of the Dow Jones Wilshire Global Index Family. The development of the global family of indexes in 2006 marks a new phase of the Dow Jones Wilshire relationship. The affiliation began in 2004 when Dow Jones Indexes and Wilshire co-branded and marketed the Dow Jones Wilshire family of indexes. By extending the Dow Jones Wilshire methodology used in the U.S. internationally, the global indexes provide unprecedented breadth, consistent global coverage, and objective and transparent rules.

Dow Jones Wilshire indexes are available on market-data vendor platforms -- many in real-time format -- and on the Dow Jones Indexes (www.djindexes.com) and Wilshire Associates (www.wilshire.com) Web sites. The Dow Jones Wilshire 5000(sm) Composite Index, the only true broad market index, is calculated and distributed by Dow Jones Indexes pursuant to an agreement between Dow Jones & Company and Wilshire Associates Incorporated. The Dow Jones Wilshire Global Total Market Index, the broadest measure of global equities, was launched in October 2006.
