China North East Petroleum (NEP) Set to Join Russell Microcap Index

HARBIN, China and NEW YORK, June 15, 2011 /PRNewswire-Asia-FirstCall/ — China North East Petroleum Holdings Limited (the “Company”) (NYSE Amex: NEP), a leading independent oil producing and oilfield services company in Northern China, will join the Russell Microcap® Index when Russell Investments reconstitutes its family of U.S. indexes on June 24, according to a preliminary list of additions posted June 10 on www.russell.com/indexes.

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.

Mr. Jingfu Li, CEO of China North East Petroleum commented, “Our inclusion in the Russell Microcap index is a milestone event for NEP and can increase our visibility within the investment community. We are pleased to be included among the well respected companies in this index and look forward to the continued execution of our strategic operational initiatives.”

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.

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.
