NON-GAAP FINANCIAL MEASURES—DEFINITIONS FFO is a supplemental non-GAAP financial measure used as a standard in the real estate industry and is a widely accepted measure of real estate investment trust (“REIT”) performance. Management believes that both FFO and Operating FFO provide additional indicators of the financial performance of a REIT. The Company also believes that FFO and Operating FFO more appropriately measure the core operations of the Company and provide benchmarks to its peer group. FFO is generally defined and calculated by the Company as net income (loss), adjusted to exclude: (i) preferred share dividends, (ii) gains and losses from disposition of depreciable real estate property and related investments, which are presented net of taxes, (iii) impairment charges on depreciable real estate property and related investments and (iv) certain non-cash items. These non-cash items principally include real property depreciation and amortization of intangibles, equity income (loss) from joint ventures and equity income (loss) from non-controlling interests and adding the Company’s proportionate share of FFO from its unconsolidated joint ventures and non-controlling interests, determined on a consistent basis. The Company’s calculation of FFO is consistent with the NAREIT definition. The Company calculates Operating FFO by excluding certain non-operating charges and gains. Operating FFO is useful to investors as the Company removes non-comparable charges and gains to analyze the results of its operations and assess performance of the core operating real estate portfolio. Other real estate companies may calculate FFO and Operating FFO in a different manner. The Company also uses Net Operating Income (“NOI”), a non-GAAP financial measure, as a supplemental performance measure. NOI is calculated herein as property revenues less property expenses and excludes all non-property and corporate level revenue and expenses. The Company believes NOI provides useful information to investors regarding the Company’s financial condition and results of operations because it reflects only those income and expense items that are incurred at the property level and, when compared across periods, reflects the impact on operations from trends in occupancy rates, rental rates, operating costs and acquisition and disposition activity on an unleveraged basis. The Company has further adjusted NOI to exclude lease termination fees, net hurricane-related losses and NOI associated with all properties sold during the first quarter ended March 31, 2018 (“Adjusted NOI”). The Company believes that FFO, OFFO and Adjusted NOI are not, and are not intended to be, presentations in accordance with GAAP. FFO, OFFO and Adjusted NOI information have their limitations as they exclude any capital expenditures associated with the re-leasing of tenant space or as needed to operate the assets. FFO, OFFO and Adjusted NOI do not represent amounts available for dividends, capital replacement or expansion, debt service obligations or other commitments and uncertainties. Management does not use FFO, OFFO and Adjusted NOI as indicators of the Company’s cash obligations and funding requirements for future commitments, acquisitions or development activities. FFO, OFFO and Adjusted NOI do not represent cash generated from operating activities in accordance with GAAP, and are not necessarily indicative of cash available to fund cash needs. FFO, OFFO and Adjusted NOI should not be considered as alternatives to net income (computed in accordance with GAAP), as indicators of operating performance or as alternatives to cash flow as a measure of liquidity. Reconciliations of these measures to the most directly comparable GAAP measure of net income (loss) has been provided herein.
