Basis of Presentation

Our consolidated financial statements include the accounts of the Company, our Operating Partnership and our subsidiaries. The equity interests of other investors in our Operating Partnership are reflected as noncontrolling interests.

All significant intercompany transactions and balances are eliminated in consolidation.

In December 2012, we sold 160 King Street. We have reclassified our financial statements for all periods prior to the sale to reflect 160 King Street as discontinued operations. Unless noted otherwise, discussions in these notes pertain to our continuing operations.

The accompanying consolidated financial statements of the Company have been prepared in accordance with the rules applicable to Form 10-Q and include all information and footnotes required for interim financial statement presentation, but do not include all disclosures required under accounting principles generally accepted in the United States (“GAAP”) for annual financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments, except as otherwise noted) considered necessary for a fair presentation have been included. These financial statements should be read in conjunction with the audited consolidated financial statements and notes therein included in the Company's annual report on Form 10-K for the year ended December 31, 2012.

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that in certain circumstances affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and revenues and expenses. These estimates are prepared using our best judgment, after considering past, current and expected events and economic conditions. Actual results could differ from these estimates.

Any reference to the number of properties and square footage are unaudited and outside the scope of our independent registered public accounting firm’s review of our financial statements in accordance with the standards of the United States Public Company Accounting Oversight Board.

Segment Information

Segment information is prepared on the same basis that our management reviews information for operational decision-making purposes. We operate in four business segments: the acquisition, redevelopment, ownership and management of retail real estate, office real estate, multifamily real estate and mixed-use real estate. The products for our retail segment primarily include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our office segment primarily include rental of office space and other tenant services, including tenant reimbursements, parking and storage space rental. The products for our multifamily segment include rental of apartments and other tenant services. The products of our mixed-use segment include rental of retail space and other tenant services, including tenant reimbursements, parking and storage space rental and operation of a 369-room all-suite hotel.

Reclassifications

Certain items in the consolidated financial statements for prior periods have been reclassified to conform to current classifications.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board issued ASU 2013-2, Comprehensive Income (Topic 220): Reporting Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-2 requires entities to disclose certain information relating to amounts reclassified out of accumulated other comprehensive income. This pronouncement became effective for us in the first quarter of 2013 and did not have a significant impact on our consolidated financial statements.
