- Definition

This element represents the disclosure related to assets and liabilities by class, including [financial] instruments measured at fair value that are classified in stockholders' equity, if any, that are measured at fair value on a recurring and/or nonrecurring basis in periods after initial recognition (for example, impaired assets). The disclosures that may be required or desired include: (a) the fair value measurements recorded during the period and the reasons for the measurements and (b) the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.
