The Dow Jones U.S. Total Market Index is part of Dow Jones Total Market Indexes, a core index family of more than 3,000 international equity indexes. The family includes world, region and country indexes, as well as economic sector, market sector, industry group and sub-group indexes. The indexes are constructed to provide 95% of free float market-capitalization coverage of developed markets and 95% coverage of emerging markets. The Dow Jones U.S. Total Market Index covers 95% of the free float market-capitalization of the U.S. market.

The Dow Jones Internet Indexes are designed and maintained according to a set of rules that were devised with the goal of providing clear, accurate views of this widely followed market segment.

For its stock to be eligible for the Internet indexes, a company must generate at least 50% of annual sales/revenues from the Internet, and be currently included in the Dow Jones U.S. Index.

Changes are being announced today after the conclusion of a regular quarterly component review.
