SRS Labs Joins Russell 2000(R) Index

SANTA ANA, Calif., June 30 /PRNewswire-FirstCall/ -- SRS Labs, Inc. (NASDAQ: SRSL) , the industry leader in surround sound, audio and voice technologies, was added to the U.S. small-cap Russell 2000(R) Index after the equity markets closed on June 26, 2009. Membership in the Russell 2000, which remains in place for one year, is based on membership in the broad-market Russell 3000(R) Index.

Annual reconstitution of Russell's U.S. indexes captures the 4,000 largest U.S. stocks ranked by total market capitalization as of the end of May. Russell determines membership for its equity indexes primarily by objective market-capitalization rankings and style attributes.

The Russell 2000 Index measures the performance of the small-cap segment of the U.S. equity universe. The Russell 2000 Index is a subset of the Russell 3000 Index representing approximately 10% of the total market capitalization of that index. The Russell 2000 is constructed to provide a comprehensive and unbiased small-cap barometer and is completely reconstituted annually to ensure larger stocks do not distort the performance and characteristics of the true small-cap opportunity set.

"The addition of SRS Labs to the Russell 2000 Index represents another milestone for our company," said Thomas C.K. Yuen, SRS Lab's chairman and CEO. "Our inclusion in the Russell 2000 expands awareness among institutional investors and the investment community of our accomplishments, as well as our strong potential for growth this year. We believe this listing is another indication that our investment in sales, marketing and engineering infrastructure over the last year is beginning to pay off in terms of increased revenue and major design wins."

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $4.4 trillion in assets currently are benchmarked to them. These investment tools originated from Russell's multi-manager investment business in the early 1980's when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers.
