Liberty Property Trust Announces Third Quarter 2014 Results

Malvern, PA — October 21, 2014 - Liberty Property Trust reported that funds from operations available to common shareholders (diluted) (“FFO”) for the third quarter of 2014 was $0.64 per share, compared to $0.57 per share for the third quarter of 2013. FFO per share was $1.80 for the nine-month period ended September 30, 2014 and $1.86 per share for the same period in 2013.

Net income per common share (diluted) was $0.23 for the quarter ended September 30, 2014, compared to $0.21 for the quarter ended September 30, 2013. Net income per common share (diluted) for the nine-month period ended September 30, 2014 was $0.92, compared to $1.11 for the same period in 2013.

Results for the first nine months of 2014 reflect the sale of 6.6 million square feet of suburban office and flex properties which closed in two installments during December 2013 and January 2014. Year-over-year results are reflective of strategic portfolio transformation activities that have increased Liberty’s industrial portfolio and decreased its suburban office exposure.

Chairman and chief executive officer Bill Hankowsky said, “As we anticipated, the industrial markets are providing fertile ground to ramp up our development pipeline, and we continue to take advantage of positive supply/demand dynamics in our industrial markets. Office markets are firming, and we are seeing increased demand, particularly for space in Class-A properties.”

Statement of Funds From Operations

(Unaudited and in thousands, except per share amounts)

The Company believes that the calculation of 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 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 Funds from operations provides useful information to the investment community about the Company’s financial performance when compared to other REITs since Funds from operations is generally recognized as the standard for reporting the operating performance of a REIT.  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. 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. Funds from operations available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by GAAP.
