NEW ORLEANS, June 30 /PRNewswire-FirstCall/ -- Hornbeck Offshore Services, Inc. (NYSE: HOS) announced today that is has been added to the Russell 2000(R) Index, a subset of the Russell 3000(R) Index.

The Russell 3000 Index measures the performance of the 3,000 largest U.S. companies ranked by total market capitalization and represents approximately 98 percent of the investable U.S. equity market. The Russell 2000 Index measures the performance of the 2,000 smallest companies within the larger index and is a leading benchmark for the small-cap market. The 21 U.S. equity indexes developed by Frank Russell Company are rebalanced annually based on May 31 total market capitalization, with the actual reconstitution effective on the first trading day following the final Friday of June each year. The Russell 2000 is constructed to provide a comprehensive and unbiased small-cap barometer and is reconstituted annually to ensure that larger stocks do not distort the performance and characteristics of the true small-cap group.
