July 27 (Reuters) - RioCan Real Estate Investment Trust REI_u.TO said second-quarter funds from operations fell 22 percent, due to the absence of gains on properties held for resale and higher interest expense.
Funds from operations, a key measure used by real estate companies, were C$67.9 million ($62.81 million), or 30 Canadian cents a unit, in the quarter, down from C$86.9 million, or 40 Canadian cents a unit, a year earlier.
Analysts had expected FFO of 32 Canadian cents a unit, according to Reuters Estimates.
RioCan said its portfolio occupancy as at June 30 was 97.1 percent compared with 97 percent a year earlier.
The trust, which owns more than 200 retail properties, said net earnings were C$27.2 million, or 12 Canadian cents a unit, in the three months ended June 30, down from C$44.8 million, or 21 Canadian cents a unit, a year ago.
RioCan units were down 13 Canadian cents at C$15.12 Monday afternoon on the Toronto Stock Exchange. ($1=1.081 Canadian Dollar) (Reporting by Ashutosh Joshi in Bangalore; Editing by Deepak Kannan)
