Accounting Policies [Abstract]
New Accounting Pronouncements	Accounting Developments Pronouncements Implemented In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-11 "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures." This ASU changes the accounting for repurchase-to-maturity transactions and linked repurchase financings so that such transactions will now be accounted for as secured borrowings. This accounting change is effective for the first interim or annual period beginning after December 15, 2014 and early adoption is not permitted. There are also new disclosure requirements in this ASU. Our adoption of ASU No. 2014-11 did not have an impact on our consolidated financial condition and results of operations. Pronouncements Not Yet Implemented In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" which supersedes the revenue recognition requirements in "Revenue Recognition (Topic 605)." The standard is principle-based and provides a five-step model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. There are also expanded disclosure requirements in this ASU. For public entities ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period and allows for either full retrospective adoption or modified retrospective adoption. We are currently evaluating the impact of ASU No. 2014-09 on our consolidated financial condition and results of operations. In June 2014, the FASB issued ASU No. 2014-12 "Compensation-Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period." This ASU was issued to address share-based payment awards with a performance target affecting vesting that could be achieved after the employee’s requisite service period. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. This ASU may be applied either (a) prospectively to all awards granted or modified after the effective date or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of ASU No. 2014-12 is not expected to have a material impact on our consolidated financial condition and results of operations. In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern." This ASU requires management to evaluate whether there are conditions or events that raise substantial doubt about the ability of a company to continue as a going concern for one year from the date the financial statements are issued or within one year after the date that the financial statements are available to be issued when applicable. Further, the ASU provides management guidance regarding its responsibility to disclose the ability of a company to continue as a going concern in the notes to the financial statements. This ASU is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The adoption of ASU No. 2014-15 is not expected to have an impact on our consolidated financial condition and results of operations. In November 2014, the FASB issued ASU 2015-01, “Income Statement-Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” In connection with the FASB's efforts to simplify accounting standards, the FASB released new guidance on simplifying Income Statement presentation by eliminating the concept of extraordinary items from U.S. GAAP. With the issuance of this ASU the FASB determined that the elimination of the concept of extraordinary items from U.S. GAAP would reduce the cost and complexity on the application of accounting standards, while maintaining or improving the usefulness of information included in financial statements. The adoption of ASU No. 2015-01 is not expected to have an impact on our consolidated financial condition and results of operations. In February 2015, the FASB issued ASU No. 2015-02, "Consolidation (Topic 810) - Amendments to the Consolidation Analysis,” which provides guidance on the analysis process companies must perform in order to determine whether a legal entity should be consolidated. The new ASU simplifies U.S. GAAP by eliminating entity specific consolidation guidance for limited partnerships. It also revises other aspects of the consolidation analysis, to include the ownership assessment of variable interest entities (VIEs), fee arrangements and how related parties are assessed. The amendments rescind the indefinite deferral of FASB Statement 167, Amendments to FASB Interpretation No. 46(R), for certain investment funds and replace it with a permanent scope exception for money market funds. ASU 2015-02 is effective for periods beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. We are currently evaluating the impact of ASU No. 2015-02 on our consolidated financial condition and results of operations. In April 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The ASU was issued in connection with the FASB's efforts to simplify accounting standards for the presentation of debt issuance costs. The amendments of this ASU require companies to present debt issuance costs the same manner that present debt discounts are currently reported, as a direct deduction from the carrying value of that debt liability. The applicability of this requirement does not impact the recognition and measurement guidance for debt issuance costs. ASU 2015-03 is effective for periods beginning after December 15, 2015. Early adoption is allowed for financial statements that have yet to be issued. The adoption of ASU No. 2015-03 is not expected to have a material impact on our consolidated financial condition and results of operations.
Fair Value	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models may be applied. Assets and liabilities recorded at fair value in our condensed consolidated balance sheets are categorized by hierarchical levels based upon the level of judgment associated with the inputs used to measure their fair values. Recurring fair value measurements are limited to investments in derivative instruments. The fair value measurements of our derivative instruments are determined using models that maximize the use of the observable market inputs including interest rate curves and both forward and spot prices for currencies, and are classified as Level II under the fair value hierarchy. The fair values of our derivatives are included in Note 4.
