TeleCommunication Systems Joins the Russell 2000 Index

ANNAPOLIS, Md., July 2, 2013 – TeleCommunication Systems, Inc. (TCS) (NASDAQ:TSYS), a world leader in highly reliable and secure mobile communication technology, was added to the U.S. small-cap Russell 2000® Index after the equity markets closed on June 28, 2013. Membership in the Russell 2000, which remains in place for one year, is based on membership in the broad-market Russell 3000® Index. The company was also added to the Russell 2000 Value Index and Russell Global Index.

“Joining the Russell 2000 Index represents an important milestone for TCS that we expect will increase awareness of our recent accomplishments, including our selection as a prime vendor for two multi-billion dollar five-year federal communications contract vehicles, and the continued monetization and expansion of our patent portfolio,” commented Maurice B. Tosé, chairman and CEO of TCS.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. Approximately $4.1 trillion in assets are benchmarked to the Russell Indexes. Russell calculates more than 700,000 benchmarks daily covering approximately 98 percent of the investable market globally, more than 80 countries and 10,000 securities. 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.
