Nonrecurring Fair Value Measurements:

Property and Property Held for Sale Impairments

Property is reviewed for impairment if events or changes in circumstances indicate that the carrying amount of the property, including any identifiable intangible assets, site costs and capitalized interest, may not be recoverable. In such an event, a comparison is made of the current and projected operating cash flows of each such property into the foreseeable future on an undiscounted basis to the carrying amount of such property. If we conclude that an impairment may have occurred, estimated fair values are determined by management utilizing cash flow models, market capitalization rates and market discount rates, or by obtaining third-party broker valuation estimates, appraisals, bona fide purchase offers or the expected sales price of an executed sales agreement in accordance with our fair value measurements accounting policy. Market capitalization rates and market discount rates are determined by reviewing current sales of similar properties and transactions, and utilizing management’s knowledge and expertise in property marketing.

No assets were measured at fair value on a nonrecurring basis at June 30, 2018. Assets measured at fair value on a nonrecurring basis at December 31, 2017 aggregated by the level in the fair value hierarchy in which those measurements fall, are as follows (in thousands):

____________


(1)	Total gains (losses) exclude impairments on disposed assets because they are no longer held by us.

(2)

In accordance with our policy of evaluating and recording impairments on the disposal of long-lived assets, property with a carrying amount of $24.9 million was written down to a fair value of $17.1 million, resulting in a loss of $7.8 million, which was included in earnings for the first quarter of 2017. Management’s estimate of fair value of these properties was determined using a bona fide purchase offer for the Level 2 inputs. See the quantitative information about the significant unobservable inputs used for our Level 3 fair value measurements table below.

Fair Value Disclosures:

Unless otherwise described below, short-term financial instruments and receivables are carried at amounts which approximate their fair values based on their highly-liquid nature, short-term maturities and/or expected interest rates for similar instruments.
