TORONTO, Nov 11 (Reuters) - Units of Boardwalk Real Estate Investment Trust BEI_u.TO fell in early trade on Thursday after Canada's biggest apartment landlord reported lower-than-expected results.
Boardwalk fell 2.2 percent to C$42.50 on the Toronto Stock Exchange on Thursday morning, the day after the REIT reported third-quarter funds from operations fell 3.9 percent and rental revenue was unchanged.
Funds from operations, a key measure of performance for real estate companies, slipped to C$33.6 million ($33.6 million), or 64 Canadian cents a unit, from C$35 million, or 66 Canadian cents a unit, a year ago.
Analysts on average were expecting earnings of 69 Canadian cents a unit, according to Thomson Reuters I/B/E/S.
The Calgary, Alberta-based REIT said the average monthly rent in the trust's portfolio for the quarter edged up to C$977 per suite, compared to C$976 a year earlier. Rental revenues in the quarter were flat at C$104.7 million.
Overall occupancy in the third quarter rose to 97.01 percent from 95.54 percent a year ago.
The REIT said because it sold some properties at the end of 2009 and this year, it now expects annual FFO to come in between C$2.40-C$2.50 per unit, compared with a previous view of C$2.40-C$2.55.
For 2011, Boardwalk estimated FFO between C$2.35-C$2.55 per unit and said it plans to invest about C$79 million into its properties through capital improvements.
The units have risen about 17 percent over the past 12 months, outperforming the main Toronto stock index slightly.
