Accounting Changes And Error Corrections [Abstract]
Comprehensive Income	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2013-02 (ASU 2013-02), “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” ASU 2013-02 requires an entity to report the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required to be reclassified in its entirety to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about those amounts. The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. For public entities, the amendments are effective prospectively for reporting periods beginning after December 15, 2012. Early adoption is permitted. The adoption of this pronouncement did not have a material impact on the Company’s results of operations or financial position.
Liabilities	In March 2013, the FASB issued ASU 2013-04, which updated the guidance in ASC Topic 405, Liabilities. The amendments in ASU 2013-04 generally provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this Update is fixed at the reporting date, except for obligations addressed within existing guidance in GAAP. The guidance requires an entity to measure those obligations as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in ASU 2013-04 also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. This guidance will become effective as of the beginning of the Company’s 2015 fiscal year. The adoption of this guidance is not expected to have a material impact on the Company’s financial position or results of operations.
Foreign Currency Matters	In March 2013, the FASB issued ASU 2013-05, “Foreign Currency Matters (Topic 830): 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” (“ASU 2013-05”). ASU 2013-05 updates accounting guidance related to the application of consolidation guidance and foreign currency matters. This guidance resolves the diversity in practice about what guidance applies to the release of the cumulative translation adjustment into net income. This guidance is effective for interim and annual periods beginning after December 15, 2013. The Company does not anticipate that these changes will have a material impact on its consolidated financial statements or disclosures.
Income taxes	In July 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740): 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”). The amendments in ASU 2013-11 require companies to present an unrecognized tax benefit, or a 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, unless the uncertain tax position is not available to reduce, or would not be used to reduce, the net operating loss or tax credit carryforward under the tax law in the same jurisdiction; otherwise, the unrecognized tax benefit should be presented as a gross liability and should not be combined with a deferred tax asset. ASU 2013-11 is effective for annual periods beginning after December 15, 2013 and should be applied to all unrecognized tax benefits that exist as of the effective date. Companies may choose to apply this guidance retrospectively to each prior reporting period presented. The Company is currently evaluating the potential impact of this update.
