Reclassifications	Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation.
New Accounting Guidance	New Accounting Guidance Accounting Standards Update: Leases In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" or ("ASC 842"), which outlines a comprehensive change to the lease accounting model and supersedes prior lease guidance. Refer to Note 2, "Leases," for information regarding our adoption of this guidance effective January 1, 2019 and a discussion of the impact to information presented herein, as well as additional required disclosures under the new guidance. Accounting Standards Update: Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU No. 2018-07, "Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting," which is intended to reduce cost and complexity and to improve financial reporting for share-based payments issued to nonemployees. The guidance is effective for fiscal years beginning after December 15, 2018 and early adoption is permitted. We adopted this guidance in first quarter 2019 and it did not have a material impact on our consolidated financial statements. Accounting Standards Update: Financial Instruments - Credit Losses In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses". This ASU introduces a new accounting model for recognizing credit losses on certain financial instruments and financial assets, including trade receivables, based upon an estimate of current expected credit losses, otherwise known as CECL. The new guidance requires the recognition of an allowance that reflects the current estimate of credit losses expected to be incurred over the life of the financial asset, based not only on historical experience and current conditions, but also on reasonable forecasts. Additionally, ASU No. 2016-13 made several changes to the available-for-sale impairment model. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted. While we are still completing our accounting assessment, we do not expect this guidance to have a material impact on our consolidated financial statements. Accounting Standards Update: Cloud Computing Arrangements In August 2018, the FASB issued ASU No. 2018-15 “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract”. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted. While we are still completing our accounting assessment, we do not expect this guidance to have a material impact on our consolidated financial statements. Accounting Standards Update: Collaborative Arrangements In November 2018, the FASB issued ASU No. 2018-18, "Collaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606". The amendments in this ASU provide guidance on how to assess whether certain transactions between collaborative arrangement participants should be accounted for within the revenue recognition standard. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and early adoption is permitted for entities who have previously adopted the new revenue recognition guidance. While we are still completing our accounting assessment, we do not expect this guidance to have a material impact on our consolidated financial statements.
