_______________


(1)	Total gains (losses) are reflected throughout 2012 and exclude impairments on disposed assets because they are no longer held by us.

(2)

In accordance with our policy of evaluating and recording impairments on the disposal of long-lived assets, property with a carrying amount of $22.4 million was written down to a fair value of $19.7 million less costs to sell of $.3 million, resulting in a loss of $3.0 million, which was included in earnings for the period. Management’s estimate of fair value of these properties was determined using a bona fide purchase offer for the Level 2 inputs. See the quantitative information about the significant unobservable inputs used for our Level 3 fair value measurements table below.

(3)

Our net investment in real estate joint ventures and partnerships with a carrying amount of $30.8 million was written down to a fair value of $24.2 million, resulting in a loss of $6.6 million, which was included in earnings for the period. Management’s estimate of fair value of this investment was determined using the weighted average of the bona fide purchase offers received for the Level 2 inputs.
