The aggregate expense charged against earnings to allocate the cost of intangible assets including deferred financing costs (nonphysical assets not used in production) in a systematic and rational manner to the periods expected to benefit from such assets. Also included in this amount is the accretion of the debt discount and the deferred financing costs which are a component of interest expense representing the periodic charge against earnings to reflect amortization of debt discounts and deferred financing costs over the life of the related debt instrument. As a noncash expense, this element is added back to net income when calculating cash provided by (used in) operations using the indirect method.
