Net operating income ("NOI") is defined as total revenue less property operating expenses, real estate taxes and third party management expenses. Segment NOI includes revenue, real estate taxes and property operating expenses directly related to operation of the properties within the respective geographical region. Segment NOI excludes property level depreciation and amortization, revenue and expenses directly associated with third party real estate management services, expenses associated with corporate administrative support services, and inter-company eliminations. NOI is the measure that is used by the Company to evaluate the operating performance of its real estate assets by segment. The Company also believes that NOI provides useful information to investors regarding its financial condition and results of operations because it reflects only those income and expenses recorded at the property level. NOI does not also reflect general and administrative expenses, interest expenses, real estate impairment losses, depreciation and amortization costs, capital expenditures and leasing costs, or trends in development and construction activities that could materially impact the Company's results from operations. All companies may not also calculate NOI in the same manner. The Company believes that net income, as defined by GAAP, is the most appropriate earnings measure. Below is a reconciliation of consolidated net operating income to consolidated income (loss) from continuing operations:
