Real Estate Acquisitions Dispositions Discontinued Operations Text Block	During 2012, we finalized the purchase price allocations for our December 2011 acquisitions of controlling interests in Montrose Crossing and Plaza El Segundo. The purchase price for Montrose Crossing was $141.5 million and our 89.9% ownership interest was $127.2 million which was funded with cash and our pro-rata share of $80.0 million of new mortgage debt. Approximately $2.9 million and $3.8 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases", respectively. The purchase price for Plaza El Segundo was $192.7 million and our 48.2% ownership interest was funded with $8.5 million of cash and the assumption of our pro-rata share of the existing $175.0 million mortgage debt. Approximately $7.5 million and $2.3 million of net assets acquired were allocated to other assets for "above market leases" and other liabilities for "below market leases", respectively. The balance sheet at December 31, 2011, has been adjusted to reflect the final purchase price allocation for both properties. In July and September 2012, we acquired three residential apartment buildings with 47 units located adjacent to Santana Row for $9.0 million. These properties provide potential future redevelopment opportunities for Santana Row.
