IMPAIRMENT CHARGES AND IMPAIRMENT OF JOINT VENTURE INVESTMENTS

The Company recorded impairment charges during the three-month periods ended March 31, 2013 and 2012, based on the difference between the carrying value of the assets or investments and the estimated fair market value as follows (in millions):


	Three-Month Periods Ended March 31,
	2013		2012
Assets marketed for sale^(A⁾	$	6.9	$	1.5

Total continuing operations	$	6.9	$	1.5


Sold assets or assets held for sale		0.8		15.8

Total discontinued operations	$	0.8	$	15.8

Joint venture investments		—		0.6

Total impairment charges	$	7.7	$	17.9

(A)	The impairment charges were triggered primarily due to the Company’s marketing of these assets for sale and management’s assessment of the likelihood and timing of a potential transaction.

Items Measured at Fair Value on a Non-Recurring Basis

For a description of the Company’s methodology on determining fair value, refer to Note 11 of the Company’s Financial Statements filed on its Annual Report on Form 10-K, as amended, for the year ended December 31, 2012.

The table also indicates the fair value hierarchy of the valuation techniques used by the Company to determine such fair value (in millions):


	Fair Value Measurements
	Level 1		Level 2		Level 3		Total		Total Losses
March 31, 2013
Long-lived assets held and used and held for sale	$	—	$	—	$	29.3	$	29.3	$	7.7

Unconsolidated joint venture investments		—		—		4.7		4.7		26.7
Deconsolidated joint venture investment		—		—		56.1		56.1		9.3

The following table presents quantitative information about the significant unobservable inputs used by the Company to determine the fair value of non-recurring items (in millions):

(A)

These fair value measurements were developed by third-party sources (including offers and comparable sales values), subject to the Company’s corroboration for reasonableness. The Company does not have access to certain unobservable inputs used by these third parties to determine these estimated fair values.

(B)	Vacant space in certain assets was valued on a price per square foot.

(C)	The fair value measurements also includes consideration of the fair market value of debt. These inputs are further described in the debt section of Note 7.

(D)	Related to loss reported in Change in Control and Sale of Interests recorded in 2012.
