The aggregate expense charged against earnings to allocate the cost of intangible assets (nonphysical assets not used in production) in a systematic and rational manner to the periods expected to benefit from such assets, combined with the amount of impairment loss recognized in the period resulting from the write-down of the carrying amount of indefinite-lived intangible assets, other than goodwill, to fair value. As a noncash expense, this element is added back to net income when calculating cash provided by (used in) operations using the indirect method.
