Accounting Policies [Abstract] |
New Accounting Policies Adopted and Pending Adoption | New Accounting Pronouncements Pending Adoption Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update for the recognition of revenue, which supersedes existing revenue recognition requirements and most industry-specific guidance. The update provides that an entity should recognize 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. This guidance is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, under either full or modified retrospective adoption. Early application is not permitted. We are currently assessing the potential impact of these changes to our consolidated financial statements as a result of adopting this standard. Discontinued Operations In April 2014, the FASB issued an accounting standards update for the requirements of reporting discontinued operations. The update provides that an entity or a group of components of an entity is required to be reported in discontinued operations once the component of an entity meets the held for sale criteria, is disposed of by sale, or is disposed of other than by sale only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results. The update also requires that additional disclosures about discontinued operations be made. This guidance is effective prospectively for annual periods, and interim reporting periods within those years, beginning after December 15, 2014, with early adoption permitted, but only for disposals, or classifications as held for sale, that have not been reported in financial statements previously issued or available for issuance. Adoption of this standard may impact the presentation of, and disclosures in, our consolidated financial statements and notes thereto. Adoption of New Accounting Pronouncements Income Taxes In July 2013, the FASB issued an accounting standards update for the reporting of an unrecognized tax benefit, or portion thereof, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The update provides an exception, requiring the unrecognized tax benefit to be presented in the financial statements as a liability when the carryforward is not available at the reporting date under the tax laws to settle additional income taxes that would result in the disallowance of a tax provision or the tax laws do not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose. This guidance is effective prospectively, with retrospective application permitted, for annual periods, and interim reporting periods within those years, beginning after December 15, 2013, with early adoption permitted. We adopted this guidance effective May 1, 2014 and it has not had, and we believe will not have, a material impact on our consolidated financial statements.
