Adjusted NOI is a non-GAAP supplemental financial measure used to evaluate the operating performance of real estate. Adjusted NOI is calculated as NOI after eliminating the effects of straight-line rents, DFL non-cash interest, amortization of market lease intangibles and lease termination fees (?non cash adjustments?). Adjusted NOI is oftentimes referred to as ?cash NOI.? The Company uses adjusted NOI to make decisions about resource allocations, and to assess and compare property level performance. The Company believes that net income (loss) is the most directly comparable U.S. GAAP measure to adjusted NOI. Adjusted NOI should not be viewed as an alternative measure of operating performance to net income (loss) as defined by GAAP since it does not reflect various excluded items. Further, the Company?s definition of Adjusted NOI may not be comparable to the definition used by other REITs or real estate companies, as they may use different methodologies for calculating Adjusted NOI.
