Whiterock REIT Announces Addition to the S&P/TSX Small Cap Index

TORONTO, Sept. 14 /CNW/ - Whiterock Real Estate Investment Trust (TSX:WRK.UN), a growth oriented REIT with a significant presence in major Canadian markets, announced today that Standard & Poor's (S&P) will add Whiterock REIT to the S&P/TSX Small Cap Index, effective after market close on Friday, September 17, 2010.

"Inclusion in the S&P/TSX Small Cap Index represents another positive milestone for Whiterock and is a testament to the significant progress we have achieved in 2010," said CEO Jason Underwood. "With a market capitalization that has increased 90% to approximately $270 million over the last nine months, we continue to look forward to the next phase of growth."

Since December 2009, Whiterock's owned and co-owned property portfolio has expanded by nearly 80% to an estimated $1.2 billion in fair market value. In that time, Whiterock has completed over $420 million of transactions and now owns and co-owns a portfolio of primarily high-quality office properties that totals approximately 6.4 million square feet in major Canadian markets such as the Greater Toronto Area, Ottawa, and Regina. In addition, 44.3% of Whiterock's interest in revenue from owned and co-owned properties consists of government and investment grade tenants.

The S&P/TSX Small Cap Index was re-developed in March 2007 to provide an investable index for Canadian investors and investment managers, as well as a small cap portfolio benchmark. To be included in the index, TSX-listed public companies must be actively and regularly traded, and have a float adjusted market capitalization between $1.5 billion and $100 million, among other eligibility characteristics.
