RECENTLY ISSUED ACCOUNTING STANDARDS: [Abstract]
Description of New Accounting Pronouncements Not yet Adopted	RECENTLY ISSUED ACCOUNTING STANDARDS: In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities, which requires an entity to disclose information about offsetting and related arrangements to enable users of financial statements to understand the effect of those arrangements on its financial position. In January 2013, the FASB issued ASU 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, which narrows the scope of the disclosure requirements to derivatives, securities borrowings, and securities lending transactions that are either offset or subject to a master netting arrangement. This guidance is effective for and was adopted by the Company in the first quarter of 2013 and required additional disclosures, but otherwise did not have a material impact on the Company's consolidated financial statements. In February 2013, the FASB issued ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which requires entities to disclose additional information about reclassification adjustments, including changes in accumulated other comprehensive income balance by component and significant items reclassified out of accumulated other comprehensive income. This guidance is effective for and was adopted by the Company in the first quarter of 2013 and required additional disclosures, but otherwise did not have a material impact on the Company's consolidated financial statements. Accounting Standards Not Yet Effective In February 2013, the FASB issued ASU 2013-04, Liabilities (Topic 405): Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date, which specifies how an entity should measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of the guidance is fixed at the reporting date and requires entities to disclose the nature and amount of the obligation as well as other information about those obligations. This guidance will be effective for annual reporting periods beginning on or after December 15, 2013, and the interim periods within those annual periods. The Company is evaluating the potential impact of the adoption of this guidance on its consolidated financial statements. 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, which provides clarification of when to release the cumulative translation adjustment into net income 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 within a foreign entity. This guidance will be effective for annual reporting periods beginning on or after December 15, 2013, and the interim periods within those annual periods. The Company does not expect the adoption of this guidance to have a material impact on its consolidated financial statements, but will have an impact on the accounting for future sales of investments or changes in control of foreign entities.
