Accounting for the Impairment or Disposal of Long-Lived Assets
Asset Impairment
The Company disposes of and anticipates the potential disposition of certain properties prior to the end of their remaining useful lives. There were no impairments recognized during the three months ended March 31, 2017 or 2016. The Company has evaluated each of its properties and land held for development and has determined that there were no valuation adjustments necessary at March 31, 2017. In addition, the Company applied reasonable estimates and judgments in determining the level of impairments recognized. Should external or internal circumstances change requiring the need to shorten the holding periods or adjust the estimated future cash flows of the Company’s assets, the Company could be required to record impairment charges in the future.
