Recently Issued Accounting Pronouncements

Discontinued Operations and Disclosures of Disposals of Components of an Entity

In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”), which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. Under the new guidance, a discontinued operation is defined as a disposal of 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.” The new standard applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The amendment is effective for annual reporting periods beginning after December 15, 2014, which for us is January 1, 2015, and interim periods within those annual periods. The adoption of this standard will not change the manner in which we currently present discontinued operations in our consolidated financial statements.

Revenue from Contracts with Customers

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. Under the new guidance, “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” The new standard provides entities the option of using either a full retrospective or a modified approach to adopt the guidance. The new standard is effective for annual reporting periods beginning after December 15, 2016, which for us is January 1, 2017, and interim periods within those annual periods. Early adoption is not permitted. We are currently evaluating the impact, if any, this new standard will have on our consolidated financial statements and have not yet determined the method of adoption.
