Accounting Policies [Abstract] |
New Accounting Policies Adopted and Pending Adoption | New Accounting Pronouncements Pending Adoption Income Taxes In July 2013, the Financial Accounting Standards Board (“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 for 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 do not expect a material impact on our consolidated financial statements as a result of adopting this standard. Adoption of New Accounting Pronouncements Comprehensive Income In February 2013, the FASB issued an accounting standards update for the reporting of reclassifications out of accumulated other comprehensive income (loss). This guidance requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income (loss) on the respective line items in net income (loss) if the amount being reclassified is required under GAAP to be reclassified in its entirety to net income (loss). For other amounts not required under GAAP to be reclassified in their entirety to net income (loss) in the same reporting period, an entity is required to cross-reference other disclosures required under GAAP that provide additional detail about those amounts. This guidance is effective prospectively for annual and interim reporting periods within those years, beginning after December 15, 2012. We adopted this guidance effective May 1, 2013 and it has not had, and we believe it will not have, a material impact on our consolidated financial statements. See Note 7 for presentation of the information required by this accounting standards update. Indefinite-Lived Intangible Assets Impairment Test In July 2012, the FASB issued an accounting standards update on indefinite-lived intangible assets impairment testing. This guidance permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative impairment test. If after assessing the totality of events or circumstances, an entity determines that it is not more likely than not that the indefinite-lived intangible assets are impaired, then the entity will not need to perform the quantitative impairment test in accordance with FASB Accounting Standards Codification (“ASC”) 350-30. This guidance is effective for annual and interim indefinite-lived assets impairment tests performed for annual reporting periods beginning after September 15, 2012, with early adoption permitted. We adopted this guidance effective May 1, 2013 and it has not had, and we believe it will not have, a material impact on our consolidated financial statements. Disclosures About Offsetting Assets and Liabilities In December 2011, the FASB issued an accounting standards update regarding the disclosure of offsetting assets and liabilities in financial statements. This guidance requires an entity to disclose both gross information and net information about both instruments and transactions eligible for offset in the statement of financial position and instruments and transactions subject to an agreement similar to a master netting arrangement. The objective of this disclosure is to facilitate comparison between those entities that prepare their financial statements on the basis of GAAP and those entities that prepare their financial statements on the basis of International Financial Reporting Standards. In January 2013, the FASB issued an accounting standards update to address implementation issues about the December 2011 accounting standards update by clarifying the scope of the offsetting disclosures. This guidance is effective for annual and interim reporting periods within those years, beginning on or after January 1, 2013. We adopted this guidance effective May 1, 2013 and it has not had, and we believe it will not have, a material impact on our consolidated financial statements.
