Funds from operations (“FFO”) is defined as net income (loss) before noncontrolling interests of unitholders, computed in accordance with generally accepted accounting principles (“GAAP”), excluding gains or losses from depreciable rental property transactions (including both acquisitions and dispositions), and impairments related to depreciable rental property, plus real estate - related depreciation and amortization . The Company believes that FFO per share is helpful to investors as one of several measures of the performance of an equity REIT . The Company further believes that as FFO per share excludes the effect of depreciation, gains (or losses) from property transactions and impairments related to depreciable rental property (all of which are based on historical costs which may be of limited relevance in evaluating current performance), FFO per share can facilitate comparison of operating performance between equity REITs . FFO per share should not be considered as an alternative to net income available to common shareholders per share as an indication of the Company’s performance or to cash flows as a measure of liquidity . FFO per share presented herein is not necessarily comparable to FFO per share presented by other real estate companies due to the fact that not all real estate companies use the same definition . However, the Company’s FFO per share is comparable to the FFO per share of real estate companies that use the current definition of the National Association of Real Estate Investment Trusts (“NAREIT”) . A reconciliation of net income per share to FFO per share is included in the financial tables above . Core FFO is defined as FFO, as adjusted for items that may distort the comparative measurement of the Company’s performance over time . Adjusted FFO ("AFFO") is defined as Core FFO less ( i ) recurring tenant improvements, leasing commissions and capital expenditures, (ii) straight - line rents and amortization of acquired above/below - market leases, net, and (iii) other non - cash income, plus (iv) other non - cash charges . Core FFO and AFFO are both non - GAAP financial measures that are not intended to represent cash flow and are not indicative of cash flows provided by operating activities as determined in accordance with GAAP . Core FFO and AFFO are presented solely as supplemental disclosures that the Company’s management believes provides useful information regarding the Company's operating performance and its ability to fund its dividends . There are not generally accepted definitions established for Core FFO or AFFO . Therefore, the Company's measures of Core FFO and AFFO may not be comparable to the Core FFO and AFFO reported by other REITs . A reconciliation of net income to Core FFO and AFFO are included in the financial tables above . Information About FFO, Core FFO and AFFO EBITDAre is a non - GAAP financial measure. The Company computes EBITDAre in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, which may n ot be comparable to EBITDAre reported by other REITs that do not compute EBITDAre in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than the Company does. The Whit e Paper on EBITDAre approved by the Board of Governors of NAREIT in September 2017 defines EBITDAre as net income (loss) (computed in accordance with Generally Accepted Accounting Principles, or GAAP), plus interest expense, plus income tax expense, plus depreciation and amortization, plus (minus) losses and gains on the dispositi on of depreciated property, plus impairment write - downs of depreciated property and investments in unconsolidated joint ventures, plus adjustments to reflect the entity's share of EBITDAre of unconsolidated joint ventures. The Company presents EBITDAre , because the Company believes that EBITDAre , along with cash flow from operating activities, investing activities and financing activities, provides investors with an a ddi tional indicator of the Company’s ability to incur and service debt. EBITDAre should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of the Compan y’s financial performance, as an alternative to net cash flows from operating activities (determined in accordance with GAAP), or as a measure of the Company’s liquidity.

Information About Net Operating Income (NOI) 42 3Q 2020 NOI represents total revenues less total operating expenses, as reconciled to net income above . The Company considers NOI to be a meaningful non - GAAP financial measure for making decisions and assessing unlevered performance of its property types and markets, as it relates to total return on assets, as opposed to levered return on equity . As properties are considered for sale and acquisition based on NOI estimates and projections, the Company utilizes this measure to make investment decisions, as well as compare the performance of its assets to those of its peers . NOI should not be considered a substitute for net income, and the Company’s use of NOI may not be comparable to similarly titled measures used by other companies . The Company calculates NOI before any allocations to noncontrolling interests, as those interests do not effect the overall performance of the individual assets being measured and assessed .

In addition, the extent to which the ongoing COVID - 19 pandemic impacts us and our tenants will depend on future developments, wh ich are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mit iga te its impact, and the direct and indirect economic effects of the pandemic and containment measures, among others.
