17. OTHER OPERATING EXPENSE
Other operating expense consists primarily of impairment charges, net losses on sales or disposals of assets and other operating expense items. The Company records impairment charges to write down certain assets to their net realizable value after an indicator of impairment is identified and subsequent analysis determines that the asset is either partially recoverable or not recoverable. These assets consisted primarily of towers and related assets, which are typically assessed on an individual basis, network location intangibles, which relate directly to towers, and tenant-related intangibles, which are assessed on a tenant basis. Net losses on sales or disposals of assets primarily relate to certain non-core towers, other assets and miscellaneous items. Other operating expenses includes acquisition-related costs and integration costs.
