Statement of Funds From Operations

December 31, 2016

(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 dispositions of depreciable property.  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 depreciable 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.
