Change to the Wilshire 4500 Index

Earlier this year, Wilshire Associates, Inc. and Dow Jones Indexes agreed to jointly maintain and publish Wilshire's indexes, including the Wilshire 4500 which the S Fund tracks.  As a result, the Wilshire 4500 has been renamed the “Dow Jones Wilshire 4500 Completion Index.”  It is called the Completion Index because if you invest in both the Dow Jones Wilshire 4500 Index and the S & P 500 Index, which the C Fund tracks, your investments will cover the total United States Stock Market.  On June 7, the Federal Retirement Thrift Investment Board adopted the new index as the S Fund benchmark.  You will be able to view the new index on both the Wilshire Web site,, and on the Dow Jones Indexes Web site,
