eMagin Corporation (NYSE Amex: EMAN), a leader in OLED microdisplays and virtual imaging technologies, today announced it will join the Russell Microcap® Index when Russell Investments reconstitutes its family of U.S. indexes on June 25, 2010 according to a preliminary list of additions posted June 11, 2010 on www.russell.com Membership in the Russell Microcap Index, which remains in place for one year, means automatic inclusion in the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes. “We are pleased that we have been selected to be included in the Russell Microcap® Index,” commented Mr. Andrew Sculley, eMagin’s president and chief executive officer. “Inclusion will bring the Company greater visibility as we continue to focus on growing our sales of active matrix OLED displays to defense, industrial and consumer markets while also delivering long-term value to our shareholders.” Annual reconstitution of Russell Indexes captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization to create the Russell 3000 ® Index and Russell Microcap. 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.
