This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.

The loss (gain) resulting from the write-down of the carrying value of assets classified as a disposal group, but one which is not further classified as a discontinued operation, to fair value less cost to sell. A (gain) results from a subsequent increase in fair value less cost to sell, but not in excess of the cumulative loss previously recognized. For example, the write-down of a disposal group subject to a plan of sale, which was not sold in the current period, to its held-for-sale value. The loss (gain) is included in income from continuing operations before income taxes in the income statement.
