New Accounting Pronouncements	New Accounting Pronouncements In October 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“Update 2016-16”), which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transaction occurs as opposed to deferring tax consequences and amortizing them into future periods. This update is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. A modified retrospective approach with a cumulative-effect adjustment directly to retained earnings at the beginning of the period of adoption is required. We are currently evaluating the effect that Update 2016-16 will have on our condensed consolidated financial statements and related disclosures. In August 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-15, Statement of Cash flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ("Update 2016-15"), which addresses the cash flow presentation of eight specific cash flow issues including, debt repayment and extinguishment costs, with the objective of reducing the existing diversity in practice. This update is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. We do not anticipate that our adoption of Update 2016-15 will have a material impact on our condensed consolidated financial statements and related disclosures. In March 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-09, Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting ("Update 2016-09"), which simplifies several aspects of accounting for share-based payment transactions including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. Transition methods vary for the related amendments. We will apply Update 2016-09 in our Annual Report on Form 10-K for the year ended December 31, 2016. We do not anticipate that our adoption of Update 2016-09 will have a material impact on our condensed consolidated financial statements and related disclosures. In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-02, Leases (Topic 842): Amendments to the FASB Accounting Standards Codification ("Update 2016-02"), which requires an entity to recognize lease assets and lease liabilities on the balance sheet and to disclose key qualitative and quantitative information about the entity's leasing arrangements. This update is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. A modified retrospective approach is required. We are currently evaluating the effect that Update 2016-02 will have on our condensed consolidated financial statements and related disclosures. During 2015, the Financial Accounting Standards Board issued Accounting Standards Update 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs ("Update 2015-03"), as updated by Update 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 Announcements at June 18, 2015 EITF Meeting ("Update 2015-15"), which require that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts. Debt issuance costs related to line-of-credit arrangements may be presented as an asset regardless of whether there are any outstanding borrowings on the arrangement. We adopted Update 2015-03 and Update 2015-15 on a retrospective basis effective January 1, 2016. Accordingly, all debt issuance costs, except for the balance related to our line-of-credit arrangement, were presented as a deduction from the carrying amount of the related debt liability on our condensed consolidated balance sheet for all periods presented. As a result of retrospective application, we reclassified debt issuance costs of $26.5 million on our condensed consolidated balance sheet as of December 31, 2015. There is no impact to the manner in which debt issuance costs are amortized in our condensed consolidated financial statements. During 2014, the Financial Accounting Standards Board issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) ("Update 2014-09"), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. During 2015, the Financial Accounting Standards Board voted to delay the effective date one year. Update 2014-09 is now effective for annual and interim periods for fiscal years beginning after December 15, 2017, though companies have an option of adopting the standard for fiscal years beginning after December 15, 2016. During 2016, the Financial Accounting Standards Board issued Accounting Standards Update 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations ("Update 2016-08"), Accounting Standards Update 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ("Update 2016-10") and Account Standards Update 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ("Update 2016-12"). The amendments in Update 2016-08, 2016-10 and 2016-12 do not change the core principle of Update 2014-09 but instead clarify the implementation guidance on principle versus agent considerations, identify performance obligations and the licensing implementation guidance, and provide narrow-scope improvements, respectively. Update 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP and may be adopted using a retrospective, modified retrospective or prospective with a cumulative catch-up approach. We are currently evaluating the effect that Update 2014-09 will have on our condensed consolidated financial statements and related disclosures.
