Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Pronouncements Not Yet Adopted In March 2013, the Financial Accounting Standards Board (“FASB”) issued guidance on the release of a cumulative translation adjustment (“CTA”) related to an entity's investment in a foreign entity into income. The guidance requires such CTA to be released when there has been a: (1) sale of a subsidiary or group of net assets within a foreign entity and the sale represents the substantially complete liquidation of the investment in the foreign entity, (2) loss of a controlling financial interest in an investment in a foreign entity or (3) step acquisition for a foreign entity. This guidance is effective for fiscal years beginning after December 15, 2013. We are currently evaluating the impact of the guidance on our financial condition and results of operations. In February 2013, the FASB issued guidance related to the measurement and disclosure of obligations resulting from joint and several liability arrangements. The new guidance requires companies to measure obligations resulting from joint and several liability arrangements as the sum of (1) the amount the company agreed to pay on the basis of its arrangement among co-obligors and (2) any additional amount the company expects to pay on behalf of its co-obligors. Additionally, the new guidance requires the disclosure of a description of the joint and several arrangement and the total outstanding amount of the obligation for all joint parties. This guidance is effective for fiscal years beginning after December 15, 2013. We are currently evaluating the impact of the guidance on our financial condition and results of operations. Recently Adopted Pronouncements In February 2013, the FASB issued guidance regarding new disclosures for items reclassified out of accumulated other comprehensive income (“AOCI”). The guidance requires entities to present information about items reclassified out of AOCI by component. Additionally, entities will be required to present either on the face of the statement where net income is presented or as a separate disclosure in the notes to the financial statements, significant amounts reclassified out of AOCI by the respective line items of net income. This guidance is effective for fiscal years beginning after December 15, 2012. The adoption of this guidance did not have a material impact on our financial statement presentation and disclosures. In July 2012, the FASB provided companies with the option to make an initial qualitative evaluation, based on events and circumstances, to determine the likelihood of an impairment of an indefinite-lived intangible asset. The results of this qualitative assessment determine whether it is necessary to perform the currently required quantitative comparison of the indefinite-lived intangible asset's fair value to its carrying amount. If it is more likely than not that the fair value of the intangible asset is less than its carrying amount, a company would be required to perform the quantitative assessment. This guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012 with early adoption permitted. The adoption of the guidance did not have a material impact on our financial condition and results of operations.
