Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board (FASB) issued an accounting standard update that amends the accounting guidance related to discontinued operations. This amendment defines discontinued operations as a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has or will have a major effect on an entity’s operations and financial results. This amendment also introduces new disclosures for disposals. The amendments in this accounting standard update are effective for fiscal years beginning after December 15, 2014 and applies to new disposals and new classifications of disposal groups as held for sale after the effective date. The accounting standard update is expected to result in fewer disposals being presented as discontinued operations and, because the guidance relates to presentation and disclosure requirements, will not affect our consolidated financial position, results of operations, or cash flows. On May 28, 2014, the FASB issued an accounting standard update which amends the accounting guidance related to revenues. This amendment will replace most of the existing revenue recognition guidance when it becomes effective. The new standard is effective for fiscal years beginning after December 15, 2016.
