Real estate investment trusts Mack-Cali Realty Corp and Alexandria Real Estate Equities Inc reported higher quarterly funds from operations (FFO), helped largely by increased rental rental revenue and lower operating costs, but projected 2010 FFO below consensus view. For 2010, Mack-Cali forecast fiscal 2010 FFO of $2.70 to $2.90 a share, below Wall Street expectations of $2.93 a share. Separately, Pasadena, California-based Alexandria Real Estate Equities expects full-year FFO of $4.42 cents a share, missing market expectations by 4 cents a share.
