Reporting of Discontinued Operations

In April 2014, the Financial Accounting Standards Board issued accounting guidance that changes the criteria for determining what should be classified as a discontinued operation and also changes the related presentation and disclosure requirements. A discontinued operation may include a component of an entity or a group of components of an entity, or a business activity.

A disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on the entity's operations and financial results when any of the following occurs: (1) The components of an entity or group of components of an entity meets the criteria to be classified as held for sale, (2) The component of an entity or group of components of an entity is disposed of by sale, or (3) The component of an entity or group of components of an entity is disposed of other than by sale (for example, by abandonment or in a distribution to owners in a spinoff).

For public business entities, this guidance should be applied prospectively to all disposals (or classifications as held for sale) of components of an entity that occur within the annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted.

The Registrants are assessing in which period they will adopt this new guidance. The new guidance will impact the amounts presented as discontinued operations on the Statements of Income and will enhance the related disclosure requirements.
