For the three and nine-month periods ended September 30, 2013, income from discontinued operations relates to the twelve properties sold by the Company during 2013, as well as one property located in West Chester, Pennsylvania designated as held-for-sale as of September 30, 2013. The Company determined the property met the criteria for assets held-for-sale pursuant to the related requirements provided for the classification as held for sale under the accounting standard for long lived assets. Accordingly, at September 30, 2013, the property is required to be measured at the lower of its carrying value or the estimated fair value less costs to sell. No provision for impairment was recognized at September 30, 2013 as the estimated fair value of the property less costs to sell are higher than the carrying value based on a purchase and sale agreement.
