PLATTEVILLE, Colo., June 14, 2012 /PRNewswire/ -- Synergy Resources Corporation (NYSE MKT: SYRG), a domestic oil and gas exploration and production company focused in the Denver-Julesburg Basin (the "D-J Basin"), today announced that it expects to be included in the Russell Microcap® Index, the Russell 3000 Index, and the Russell Global Index when Russell Investments reconstitutes its family of U.S. indexes on June 25, according to a preliminary list of additions posted June 8 on www.russell.com. Membership in the Russell Indexes remains in place for one year. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes. Frank L. Jennings, Chief Financial Officer of Synergy Resources, said, "We are pleased to be included in the 2012 reconstitution of the Russell Indexes. Our new presence in three of the indexes recognizes our growth as an emerging energy provider." Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. In the institutional marketplace, an industry-leading $3.9 trillion in assets currently are benchmarked to them. Russell calculates more than 80,000 benchmarks daily covering approximately 98 percent of the investable market globally, 83 countries and more than 10,000 securities. 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 Index. 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. Total returns data for the Russell Indexes is available at http://www.russell.com/indexes/data/US_Equity/Russell_US_Index_returns.asp.
