New Accounting Standards	2. NEW ACCOUNTING STANDARDS Recently adopted accounting guidance In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which increases transparency and comparability by requiring the recognition of lease assets and lease liabilities on the balance sheet, as well as requiring the disclosure of key information about leasing arrangements. On January 1, 2019, we adopted ASU No. 2016-02, Leases (ASC Topic 842), on a modified retrospective basis under the optional transition method. Therefore, the application of the provisions of this ASU are effective January 1, 2019, and comparative periods are presented in accordance with ASC Topic 840. Additionally, we elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed us to carry forward (1) our historical lease classification and assessments for expired and existing leases, and (2) our historical accounting for initial direct costs for existing leases. We elected not to record on the Condensed Consolidated Balance Sheets any lease whose term is 12 months or less and does not include a purchase option that we are reasonably certain to exercise. We also elected to account for the non-lease components within our leases as part of the single lease component to which they are related. The most significant impact of the adoption of this ASU was an increase to the Condensed Consolidated Balance Sheets to reflect operating lease right-of-use assets and lease liabilities, which are primarily associated with our office leases around the world. Our accounting for finance leases was not materially impacted. See Note 9, Leases, for additional information on the impact of ASC 842 adoption. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates Step 2 from the goodwill impairment test. The annual goodwill impairment test will require companies to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge when the carrying amount exceeds the fair value of the reporting unit. This ASU is effective for annual and interim goodwill impairment tests beginning after December 15, 2019, with early adoption permitted. We adopted this guidance effective January 1, 2019, and, as a result, will no longer apply Step 2 when performing the goodwill impairment test. This guidance had no material impact on our financial statements and related disclosures. Recently issued accounting guidance, not yet adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), which creates a new framework to evaluate financial instruments, such as trade receivables, for expected credit losses. This new framework replaces the existing incurred loss approach and is expected to result in more timely recognition of credit losses. ASU No. 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is not permitted until years beginning after December 15, 2018. We are continuing to evaluate the effect this guidance will have on our financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC 350-40 when determining which implementation costs to capitalize as intangible assets. This ASU is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. We do not believe this guidance will have a material impact on our financial statements and related disclosures.
