Occupancy: At June 30, 2017, Liberty’s operating portfolio of 98.9 million square feet was 95.6% occupied, compared to 96.1% at the end of the first quarter 2017. During the quarter, Liberty completed lease transactions totaling 6.5 million square feet of space, and occupancy on a signed but not yet commenced basis is 97.2%.

Industrial distribution rents increased 11.9% on renewal and replacement leases signed during the quarter.  96% of these leases have built-in rent escalators.

Statement of Funds from Operations

June 30, 2017

(Unaudited and in thousands, except per share amounts)

NAREIT Funds from Operations available to common shareholders is defined by NAREIT as net income (computed in accordance with U.S. GAAP), excluding gains (or losses) from sales of depreciable property and impairments of depreciable real estate assets, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures.  The SEC has agreed to the disclosure of this non-GAAP financial measure on a per share basis in its Release No. 34-47226, Conditions for Use of Non-GAAP Financial Measures. The Company believes that the calculation of NAREIT FFO 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 operating property dispositions. As a result, year over year comparison of NAREIT FFO 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 FFO provides useful information to the investment community about the Company’s financial performance when compared to other REITs since NAREIT FFO is generally recognized as the standard for reporting the operating performance of a REIT. NAREIT FFO available to common shareholders does not represent net income or cash flows from operations as defined by U.S. 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 FFO available to common shareholders also does not represent cash flows generated from operating, investing or financing activities as defined by U.S. GAAP. The Company believes that the line on its consolidated statements of comprehensive income entitled “net income available to common shareholders” is the most directly comparable U.S. GAAP measure to FFO.
