CyrusOne Inc. to Join Russell 2000 Index

DALLAS, March 27, 2013 (GLOBE NEWSWIRE) -- CyrusOne Inc. (Nasdaq:CONE), today announced that it is set to join the Russell 2000 and Russell 3000 Indices, following Russell Investments' first quarter IPO additions to its comprehensive set of global equity indices on March 28, according to a preliminary list of additions posted March 15 on

Gary Wojtaszek, President and Chief Executive Officer of CyrusOne, commented, "We are very pleased to join the Russell family of Indices. The inclusion of CyrusOne in the Russell 2000 Index is an important step in the progression of our company. In addition, it represents a significant opportunity to increase our visibility within the investor community."

Membership in the Russell 2000®, which remains in place for one year, includes automatic inclusion into the broader Russell 3000® Index as well as the appropriate growth and style indices. The Russell 2000 Index measures the performance of the small-cap segment of the U.S. equity universe and is a subset of the Russell 3000 Index, representing approximately 10% of the total market capitalization of that index.

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 determines membership for its equity indices primarily by objective, market capitalization rankings, and style attributes.
