[1] | As of December 31, 2015, the 58 properties associated with the series of related transactions with Och-Ziff Real Estate were classified as held for sale on the consolidated balance sheets. On February 4, 2016, the Company completed the series of transactions, resulting in the disposition of the properties. See Note 3, “Real Estate Investments,” for further information regarding the disposition. The sale is not classified as a significant disposition under the accounting guidance for discontinued operations.
[2] | As of December 31, 2015, the office property located at 2970 Market Street in Philadelphia, Pennsylvania commonly known as 30th Street Main Post Office (“Cira Square”) was classified as held for sale on the consolidated balance sheets. The Company disposed of its interests in the property on February 5, 2016. See Note 3, "Real Estate Investments," for further information. The sale is not classified as a significant disposition under the accounting guidance for discontinued operations.
[3] | Real estate investments related to assets held for sale above represents gross real estate assets and does not include accumulated depreciation or intangible assets on the balance sheets of the properties held for sale.
[4] | As a result of the Och-Ziff Sale that occurred on February 4, 2016, the Company narrowed its segments to five segments located in: (1) Pennsylvania Suburbs, (2) Philadelphia Central Business District (“CBD”), (3) Metropolitan Washington, D.C. and (4) Austin, Texas. The Och-Ziff Sale disposed of the entire Richmond, Virginia segment. Subsequent to the Och-Ziff Sale, the segments previously defined as New Jersey/Delaware and California are now being managed as a consolidated segment entitled (5) “Other,” as these geographies no longer provide a significant revenue contribution. Accordingly, the chief operating decision maker revised the management structure, reallocated resources, and is assessing business operations of the five segments as of January 1, 2016.
