BIOLASE Technology, Inc. Set to Join Russell Global Index

IRVINE, CA--(Marketwire - June 21, 2011) - BIOLASE Technology, Inc. (NASDAQ: BLTI), the World’s leading dental laser manufacturer and distributor, today announced that it is set to join the Russell Global Index when Russell Investments reconstitutes its comprehensive set of global equity indexes on June 24, 2011, according to a preliminary list of additions posted June 10, 2011, available at www.russell.com/indexes. Final membership lists will be made available to index funds and their managers on June 27, 2011.

Membership in the Russell Global Index, which remains in place for one year, means automatic inclusion in the appropriate large-cap, small-cap, all-cap indexes as well as the applicable style, sector and country indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes.

Federico Pignatelli, Chairman and CEO, said, “We are pleased to be selected for the Russell Global Index. This, along with our recent inclusion in the Russell 2000® Index, represents another important step in growing our presence and visibility in the investment community and highlights our considerable achievements over the past several quarters.”

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 $3.9 trillion in institutional assets currently are benchmarked to them.

The Russell Global Index is reconstituted annually and all sub-indexes are recalibrated simultaneously to accurately measure current market realities for each market segment. These investment tools originated from Russell’s multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers.

Russell launched the Russell Global Index in 2007, leveraging the popular methodology from its U.S. indexes. The broad-market Russell 3000® Index serves as the U.S. component to the Russell Global Index.
