The quarterly increase was primarily attributable to a rise in rental revenues. Rental revenues were up 7.7% year over year to $650.5 million, aided by an uptick in base rents, higher tenant recoveries and parking & other revenues.Property UpdateAs of Mar 31, 2016, Boston Properties’ portfolio comprised of 167 properties, spanning over around 46.3 million square feet area.

Yet, any further rise in interest rates and stiff competition in some of its markets keep us concerned.Boston Properties currently carries a Zacks Rank #3 (Hold).We now look forward to other REITs that are scheduled to release first-quarter 2016 results next week. These include General Growth Properties, Inc GGP, Taubman Centers, Inc. TCO and Vornado Realty Trust VNO.Note: FFO, a widely used metric to gauge the performance of REITs, is obtained after adding depreciation and amortization and other non-cash expenses to net income.Want the latest recommendations from Zacks Investment Research?
