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. 2014-12 "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. Our adoption of ASU No. 2014-12 effective January 1, 2016 did not have an impact on our consolidated financial condition and results of operations. In November 2014, the FASB issued ASU No. 2014-16, "Derivatives and Hedging (Topic 815): "Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity." This ASU was issued to clarify and reinforce the practice of evaluating all relevant terms and features when reviewing the nature of a host contract. Our adoption of ASU No. 2014-16 effective January 1, 2016 did not have an impact on our consolidated financial condition and results of operations. In January 2015, 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 accounting principles generally accepted in the U.S. (“U.S. GAAP”). Our adoption of ASU No. 2015-01 effective January 1, 2016 did not 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. Our adoption of ASU No. 2015-02 effective January 1, 2016 did not have an impact 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 ASU requires companies to present debt issuance costs in the same manner that 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. In August 2015, the FASB issued ASU 2015-15, "Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements—Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (SEC Update)." In this ASU the SEC staff announced that it would "not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement." We adopted the provisions of ASU 2015-03 and ASU 2015-15 as of January 1, 2016. Prior period amounts have been reclassified to conform to the current period presentation. As of December 31, 2015, $10.3 million of debt issuance costs were reclassified in our consolidated balance sheet from other assets, net to long-term debt. Our adoption of ASU No. 2015-03 and ASU No. 2015-15 did not have an impact on our consolidated results of operations. In May 2015, the FASB issued ASU No. 2015-07, "Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent) (a consensus of the Emerging Issues Task Force)." The ASU removes the requirement to categorize all investments for which fair value is measured using the net asset value per share practical expedient within the fair value hierarchy. Our adoption of ASU No. 2015-07 effective January 1, 2016 did not have an impact on our consolidated financial condition and results of operations. In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes to simplify the presentation of deferred income taxes. The ASU requires that deferred tax liabilities and assets be classified as noncurrent on the balance sheet. We adopted ASU No. 2015-17 effective January 1, 2016 and as a result, prior period amounts have been reclassified to conform to the current period presentation. As of December 31, 2015, $156.0 million of deferred tax assets and $11.4 million of deferred tax liabilities were reclassified from current to noncurrent on our balance sheet. Our adoption of ASU No. 2015-17 did not have an impact on our consolidated 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. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date." As a result, public entities will apply the new standard for annual reporting periods beginning after December 15, 2017, including interim periods within those reporting periods. Early adoption as of the original public entity effective date is permitted. In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations". This update is simply a clarification of the implementation guidance on principle versus agent considerations. In April 2016, the FASB issued ASU No. 2016-10, “Identifying Performance Obligations and Licensing", which amends certain aspects of ASU No. 2014-09. In May 2016, the FASB issued ASU No. 2016-11, "Rescission of SEC Guidance Because of ASU No. 2014-09 and ASU No. 2014-16; this ASU rescinds specific SEC guidance on accounting for shipping and handling fees and costs and consideration given by a vendor to a customer. Additionally, in May 2016, the FASB issued ASU No. 2016-12, "Revenue from Contracts with Customers (Topic 606), Narrow-Scope Improvements and Practical Expedients." This ASU amends and clarifies the ASU No. 2016-09 guidance on assessing collectibility, presenting sales taxes, measuring non-cash consideration, and certain transition matters. We are currently evaluating the impact of ASU No. 2014-09 and all related ASU's on our consolidated financial condition and results of operations. Although we are continuing to evaluate, upon initial qualitative evaluation, we believe some anticipated key changes upon adoption will be potentially increased “over-time” revenue recognition and potential changes to the balance sheet related to accounts receivable, contract assets and contract liabilities. 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 July 2015, the FASB issued ASU No. 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory." The ASU updates represent changes to simplify the subsequent measurement of inventory. Previous to the issuance of this ASU, ASC 330 required that an entity measure inventory at the lower of cost or market. The amendments of ASU 2015-11 update narrows that “market” requirement to “net realizable value,” which is defined by the ASU as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This ASU is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016. Application of this ASU is to be made prospectively, earlier application is permitted as of the beginning of an interim or annual reporting period. The adoption of ASU No. 2015-11 is not expected to have a material impact on our consolidated financial condition and results of operations. In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The ASU requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value with changes in fair value recognized in net income. The ASU also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The requirement to disclose the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost on the balance sheet has been eliminated by this ASU. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are currently evaluating the impact of ASU No. 2016-01 on our consolidated financial condition and results of operations. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. The ASU requires that organizations that lease assets recognize assets and liabilities on the balance sheet for the rights and obligations created by those leases. The ASU will affect the presentation of lease related expenses on the income statement and statement of cash flows and will increase the required disclosures related to leases. This ASU is effective for annual periods ending after December 15, 2018, and interim periods thereafter, with early adoption permitted. We are currently evaluating the impact of ASU No. 2016-02 on our consolidated financial condition and results of operations. Although we are continuing to evaluate, upon initial qualitative evaluation, we believe a key change upon adoption will be the balance sheet recognition of leased assets and liabilities. Based on our qualitative evaluation to date, we believe that any changes in income statement recognition will not be material. In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting." The ASU affects the accounting for employee share-based payment transactions as it relates to accounting for income taxes, accounting for forfeitures, and statutory tax withholding requirements. This ASU is effective for annual periods ending after December 15, 2016, and interim periods within those periods with early adoption permitted. We are currently evaluating the impact of ASU No. 2016-09 on our consolidated financial condition and results of operations. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the current incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are currently evaluating the impact of ASU No. 2016-13 on our consolidated financial condition and results of operations.
Fair Value	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.
