(1)Represents rental and related revenues, tenant recoveries, and income from DFLs.

(2)NOI is a non-GAAP supplemental financial measure used to evaluate the operating performance of real estate. The Company defines NOI as rental and related revenues, including tenant recoveries, resident fees and services, and income from direct financing leases, less property level operating expenses. NOI excludes interest income, investment management fee income, interest expense, depreciation and amortization, general and administrative expenses, litigation settlement, impairments, impairment recoveries, other income, net, income taxes, equity income from and impairments of investments in unconsolidated joint ventures, and discontinued operations. The Company believes NOI provides relevant and useful information because it reflects only income and operating expense items that are incurred at the property level and presents them on an unleveraged basis. Adjusted NOI is calculated as NOI after eliminating the effects of straight-line rents, DFL accretion, amortization of above and below market lease intangibles, and lease termination fees. Adjusted NOI is sometimes referred to as “cash NOI.” The Company uses NOI and adjusted NOI to make decisions about resource allocations and to assess and compare property level performance. The Company believes that net income is the most directly comparable GAAP measure to NOI. NOI should not be viewed as an alternative measure of operating performance to net income as defined by GAAP because it does not reflect the aforementioned excluded items. Further, the Company’s definition of NOI may not be comparable to the definition used by other REITs, as those companies may use different methodologies for calculating NOI.
