Impairments
Impairments	14. Impairments We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. A provision is made for impairment if estimated future operating cash flows (undiscounted and without interest charges) plus estimated disposition proceeds (undiscounted) are less than the current book value of the property. Key factors that we utilize in this analysis include projected rental rates, estimated holding periods, historical sales and releases, capital expenditures and property sales capitalization rates. If a property is classified as held for sale, it is carried at the lower of carrying cost or estimated fair value, less estimated cost to sell, and depreciation of the property ceases. During the third quarter of 2017, we recorded total provisions for impairment of $365,000 on three sold properties. For the first nine months of 2017, we recorded total provisions for impairment of $8.1 million on ten sold properties, one property classified as held for sale, and six properties classified as held for investment. In comparison, for the third quarter of 2016, we recorded total provisions for impairment of $8.8 million on 15 sold properties, two properties classified as held for investment, and one property classified as held for sale. For the first nine months of 2016, we recorded total provisions for impairment of $17.0 million on 29 sold properties, two properties classified as held for investment, and one property classified as held for sale.
