- Definition

Sum of the carrying amounts of both indefinite-lived and finite-lived intangible assets. The carrying amount of indefinite-lived intangible assets is the original costs for current and prior period additions, adjusted for impairments, if any, as of the balance sheet date. Balances are impacted by translation. The carrying amount of finite-lived intangible assets is the cost before accumulated amortization as of the balance sheet date.
