The aggregate amount of recurring noncash expense charged against earnings in the period to allocate the cost of intangible assets over their estimated remaining economic lives and transactions that result in no cash inflows or outflows in the period in which they occur, but affect net income and thus are removed when calculating net cash flow from operating activities using the indirect method. This element is used when there is not a more specific and appropriate element.
