- Definition

Tabular disclosure of characteristics and cost, by total and major class, of indefinite-lived intangible assets acquired as part of a business combination. Indefinite-lived intangible assets are assets that have no physical form, but have expected future economic benefit. The future benefit is not expected to diminish over a stated period of time. Acquired indefinite-lived intangible assets are disclosed by major class (assets that can be grouped together because they are similar, either by their nature or by their use in operations of the entity) and in total.
