April 29 (Reuters) - Commercial real estate investment trust Mack-Cali Realty Corp (CLI.N) reported lower quarterly funds from operations as the sector struggles to recover from one of the worst slumps since the early 1990s.
For the first quarter, the office landlord posted FFO of $66.5 million, or 72 cents a share, compared with FFO of $68.1 million, or 84 cents a share a year earlier.
Analysts on average were expecting the company to report FFO of 72 cents a share.
FFO, a performance metric, removes the profit-reducing effect of depreciation, a non-cash item.
Consolidated in-service portfolio leased fell to 88.8 percent, compared with 90.7 percent a year ago.
