Malvern, PA, October 27, 2015 - Liberty Property Trust reported that funds from operations available to common shareholders (diluted) (“FFO”) for the third quarter of 2015 was $0.67 per share, compared to $0.64 per share for the third quarter of 2014.

Net income per common share (diluted) was $0.61 per share for the third quarter of 2015, compared to $0.23 per share for the third quarter of 2014. Net income for the third quarter of 2015 reflects gain on sale of $0.36 per share compared with immaterial gains for the same period in 2014. Net income for the nine months ended September 30, 2015 was $1.06 per share, compared to $0.92 per share for the same period in 2014.

“Liberty’s third quarter results reflect the increasing quality of our portfolio and the outstanding real estate environment we are operating in,” said Bill Hankowsky, chairman and chief executive officer. “The industrial market is firing on all cylinders and the office market is firming. Tenant demand resulted in a significant increase in development starts in the third quarter, and the robust activity we experienced throughout the summer is maintaining stride so far in the fourth quarter. We are focused on increasing rents and executing on our portfolio-transforming disposition strategy. We now believe our dispositions for 2015 will be in the range of $600-$700 million, exceeding our previous guidance of $525-$625 million.”

Statement of Funds From Operations

(Unaudited and in thousands, except per share amounts)

The Company believes that the calculation of NAREIT Funds from operations is helpful to investors and management as it is a measure of the Company’s operating performance that excludes depreciation and amortization and gains and losses from property dispositions.  As a result, year over year comparison of NAREIT Funds from operations reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, development activities, general and administrative expenses, and interest costs, providing perspective not immediately apparent from net income.  In addition, management believes that NAREIT Funds from operations provides useful information to the investment community about the Company’s financial performance when compared to other REITs since NAREIT Funds from operations is generally recognized as the standard for reporting the operating performance of a REIT.  NAREIT Funds from operations available to common shareholders is defined by NAREIT as net income (computed in accordance with generally accepted accounting principles (“GAAP”)), excluding gains (or losses) from sales of property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. NAREIT Funds from operations available to common shareholders does not represent net income or cash flows from operations as defined by GAAP and does not necessarily indicate that cash flows will be sufficient to fund cash needs. It should not be considered as an alternative to net income as an indicator of the Company’s operating performance or to cash flows as a measure of liquidity. NAREIT Funds from operations available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by GAAP.
