NON - GAAP FINANCIAL MEASURES One Liberty compute funds from operations, or FFO, in accordance with the “White Paper on Funds From Operations” issued by the National Association of Real Estate Investment Trusts (“NAREIT”) and NAREIT’s related guidance. FFO is defined in the White Paper as net income (calculated in accordance with GAAP), excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control, impairment write - downs of certain real estate assets and investments in entities where the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. Adjustments for unconsolidated partnerships and joint ventures are calculated to reflect FFO on the same basis. In computing FFO, One Liberty does not add back to net income the amortization of costs in connection with its financing activities or depreciation of non - real estate assets. One Liberty computes adjusted funds from operations, or AFFO, by adjusting from FFO for our straight - line rent accruals and amortization of lease intangibles, deducting from income, additional rent from a ground lease tenant, income on settlement of litigation, income on insurance recoveries from casualties, lease termination and assignment fees, and adding back to income amortization of restricted stock and restricted stock unit compensation expense, amortization of costs in connection with its financing activities (including our share of our unconsolidated joint ventures), debt prepayment costs and amortization of lease incentives and mortgage intangible assets. Since the NAREIT White Paper does not provide guidelines for computing AFFO, the computation of AFFO varies from one REIT to another. One Liberty believes that FFO and AFFO are useful and standard supplemental measures of the operating performance for equity REITs and are used frequently by securities analysts, investors and other interested parties in evaluating equity REITs, many of which present FFO and AFFO when reporting their operating results. FFO and AFFO are intended to exclude GAAP historical cost depreciation and amortization of real estate assets, which assumes that the value of real estate assets diminish predictably over time. In fact, real estate values have historically risen and fallen with market conditions. As a result, management believes that FFO and AFFO provide a performance measure that when compared year over year, should reflect the impact to operations from trends in occupancy rates, rental rates, operating costs, interest costs and other matters without the inclusion of depreciation and amortization, providing a perspective that may not be necessarily apparent from net income. Management also considers FFO and AFFO to be useful in evaluating potential property acquisitions. FFO and AFFO do not represent net income or cash flows from operating, investing, or financing activities as defined by GAAP. FFO and AFFO should not be considered to be an alternative to net income as a reliable measure of our operating performance; nor an alternative to cash flows from operating, investing or financing activities (as defined by GAAP) as measures of liquidity. FFO and AFFO do not measure whether cash flow is sufficient to fund all of our cash needs, including principal amortization, capital improvements and distributions to stockholders. Management recognizes that there are limitations in the use of FFO and AFFO. In evaluating our performance, management is careful to examine GAAP measures such as net income and cash flows from operating, investing and financing activities.
