[1] Piedmont sold the 1111 Durham Avenue building in South Plainfield, New Jersey and recorded an impairment charge of $6.4 million based on the difference between carrying value and fair value of the asset at the time it was reclassified from real estate assets held-for-use (at cost) to real estate assets held for sale (at estimated fair value). The fair value measurement used in the evaluation of this non-financial asset was based upon the amount set forth in the purchaser's original letter of intent which approximated the land value of the asset due to the age of construction and lack of near term leasing prospects for the building.
