(1)

The summation of the quarterly financial data may not equal the annual number reported on the consolidated statements of operations due to rounding. The summation of the quarterly net income (loss) available to common stockholders per share does not equal the annual number reported on the consolidated statements of operations due to the impact of equity offerings that occurred during the years ended December 31, 2012 and 2011.

(2)

Net Operating Income is defined as operating revenues (rental income, tenant reimbursements, and other property income) less property and related expenses (property expenses, real estate taxes, ground leases, and provisions for bad debts) and excludes other non−property related income and expenses such as interest income and other net investment gains (losses) and interest expense, depreciation and amortization, acquisition−related expenses and corporate general and administrative expenses.


(3)	All periods have been adjusted from amounts previously disclosed in our quarterly filings on Form 10-Q to reclassify amounts related to discontinued operations (see Note 17).
