   in the Company&amp;#8217;s statement of operations. For the nine months ended September&amp;#160;30, 2009, $6.0
   million in impairment related to properties sold was included in discontinued operations in the
   Company&amp;#8217;s statement of operations and $3.3&amp;#160;million was included in gain (loss)&amp;#160;on property
   dispositions in the Company&amp;#8217;s statement of operations. The Company determined these impairments
   through a comparison of the aggregate future cash flows (including quoted offer prices) to be
   generated by the properties to the carrying value of the
   properties. The Company has evaluated each of the properties and land held for development and has
   determined that there are no additional valuation adjustments necessary at September&amp;#160;30, 2010.

   Company determined these impairments through a comparison of the aggregate future cash flows
   (including quoted offer prices) to be generated by the properties to the carrying value of the
   properties. The Company has evaluated each of the properties and land held for development and has
   determined that there are no additional valuation adjustments necessary at September&amp;#160;30, 2010.
