Under the amended guidance, a discontinued operation is defined as the disposal of a component that represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. The amended guidance also requires expanded disclosures about discontinued operations and disposals of a significant part of an entity that do not qualify as discontinued operations. The amended guidance is effective prospectively to new disposals and new classifications of assets held for sale in annual periods beginning after December 15, 2014, and interim periods within those annual periods.
