Entities with other types of financial assets and financial liabilities subject to a master netting arrangement or similar agreement are no longer subject to the disclosure requirements in ASU 2011-11. The guidance is effective for annual periods beginning on or after January 1, 2013 and interim periods within those annual periods. Disclosures are to be provided retrospectively for all periods presented. The adoption of this update did not have an impact on the Company's condensed consolidated financial statements. In February 2013, the FASB issued ASU 2013-02, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income," which requires entities to disclose additional information for items reclassified out of accumulated other comprehensive income ("AOCI"). For items reclassified out of AOCI and into net earnings in their entirety, entities are required to disclose the effect of the reclassification in each affected line in the statement of earnings. For AOCI reclassification items that are not reclassified in their entirety into net earnings, a cross reference to other required U.S. GAAP disclosures is required. This information may be provided either in the notes or parenthetically on the face of the statement that reports net earnings as long as all the information is disclosed in a single location. However, an entity is prohibited from providing this information parenthetically on the face of the statement that reports net earnings if it has items that are not reclassified in their entirety into net earnings. The adoption of this update did not have a material impact on the Company's condensed consolidated financial statements; however, the Company provided additional disclosures as required by ASU 2013-02 in Note C, "Comprehensive Income," in the notes to the condensed consolidated financial statements. In March 2013, the FASB issued ASU 2013-05, "Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity," which applies to the release of the cumulative translation adjustment into net earnings when a parent either sells a part or all of its investment in a foreign entity, or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. The guidance requires that a parent deconsolidate a subsidiary or derecognize a group of assets that is a business if the parent ceases to have a controlling financial interest in that group of assets, and resolves the diversity in practice for the treatment of business combinations achieved in stages involving a foreign entity. The guidance is effective for annual and interim reporting periods beginning after December 15, 2013. The adoption of this update will not have a material impact on the consolidated financial statements of the Company. In July 2013, the FASB issued 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASU 2013-11), which requires entities to present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss (“NOL”) or tax credit carryforward whenever the NOL or tax credit carryforward would be available to reduce the additional taxable income or tax due if the tax position is disallowed. This accounting standard update requires entities to assess whether to net the unrecognized tax benefit with a deferred tax asset as of the reporting date. This guidance is effective for fiscal years beginning after December 15, 2013. The Company is not anticipating adoption of this update to have a material impact on the Company's consolidated financial statements.
