Quantitative threshold of revenues, profit or loss and assets for identifying reportable segments			The Company has a single operating segment. The Company’s shopping centers have common characteristics and are managed on a consolidated basis. The Company does not differentiate among properties on a geographical basis or any other basis for purposes of allocating resources or capital. The Company’s Chief Operating Decision Maker (“CODM”) may review operational and financial data on an ad-hoc basis at a property level. The CODM assesses performance for the segment and decides how to allocate resources based on net income as reported on the Company’s consolidated statements of operations. In addition, the CODM uses net operating income (“NOI”) as a supplemental measure to evaluate and assess the performance of the Company’s operating portfolio. NOI is defined as property revenues less property-related expenses and excludes depreciation and amortization expense, joint venture equity and fee income, interest income and expenses and corporate level transactions. The CODM uses net income and NOI to monitor budget versus actual results in assessing the performance of the Company’s properties to guide decisions regarding timing of property sales and payment of dividends. The CODM reviews significant expenses associated with the Company’s single reportable operating segment which are presented in the Company’s consolidated statements of operations. The measure of segment assets is reported in the Company’s consolidated balance sheets as total consolidated assets.
