New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Accounting Pronouncements	Accounting Pronouncements Newly Adopted Accounting Standards In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities,” (“ASU 2017-12”) to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018 (our fiscal year 2020), including interim periods within that reporting period. We early adopted ASU 2017-12 effective August 1, 2018. The adoption of ASU 2017-12 did not have a material impact on our financial position, results of operations or cash flows. In May 2017, the FASB issued ASU 2017-09, “(Topic 718) Scope of Modification Accounting,” (“ASU 2017-09”) to provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in ASC 718. ASU 2017-09 is effective for fiscal years beginning after December 15, 2017 (our fiscal year 2019), including interim periods within that reporting period. Accordingly, we adopted ASU 2017-09 on August 1, 2018. The adoption of ASU 2017-09 did not have a material impact on our financial position, results of operations or cash flows. In August 2016, the FASB issued ASU 2016-15, “(Topic 230) Classification of Certain Cash Receipts and Cash Payments,” (“ASU 2016-15”). This guidance makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017 (our fiscal year 2019). Accordingly, we adopted ASU 2016-15 on August 1, 2018. The adoption of ASU 2016-15 did not have a material impact on our financial position, results of operations or cash flows. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2014-09”), which supersedes the revenue recognition requirements in Accounting Standards Codification 605, “Revenue Recognition” (“ASC 605”). ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. It also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2015-14”), which defers the effective date of ASU 2014-09 by one year to fiscal years beginning after December 15, 2017 (our fiscal year 2019), including interim periods within that reporting period. In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2016-12”), which provided narrow scope improvements and practical expedients relating to ASU 2014-09. We adopted the collective standard (“ASC 606”) on August 1, 2018. See Note 5, “Revenue Recognition” for a discussion of the impact and required disclosures. Recently Issued Accounting Standards In August 2018, the FASB issued ASU 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” (“ASU 2018-15”) to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement) by providing guidance for determining when the arrangement includes a software license. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019 (our fiscal year 2021), including interim periods within that reporting period. The adoption of ASU 2018-15 is not expected to have a material impact on our financial position, results of operations or cash flows. In August 2018, the FASB issued ASU 2018-13, “Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”) to modify the disclosure requirements on fair value measurements in ASC 820, “Fair Value Measurement”. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019 (our fiscal year 2021), including interim periods within that reporting period. The adoption of ASU 2018-13 is not expected to have a material impact on our financial position, results of operations or cash flows. In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU 2018-02”) to allow for the reclassification from accumulated other comprehensive income to retained earnings of stranded tax effects resulting from the Tax Cuts and Jobs Act enacted in December 2017. ASU 2018-02 is effective for fiscal years beginning after December 15, 2018 (our fiscal year 2020), including interim periods within that reporting period. The adoption of ASU 2018-02 is not expected to have a material impact on our financial position, results of operations or cash flows. In January 2017, the FASB issued ASU 2017-04, “(Topic 350) Simplifying the Test for Goodwill Impairment,” (“ASU 2017-04”) to simplify the test for goodwill impairment. The revised guidance eliminates the existing Step 2 of the goodwill impairment test which required an entity to compute the implied fair value of its goodwill at the testing date in order to measure the amount of the impairment charge when the fair value of the reporting unit failed Step 1 of the goodwill impairment test. The guidance will be applied on a prospective basis on or after the effective date. ASU 2017-04 is effective for fiscal years beginning after December 31, 2019 (our fiscal year 2021) and early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU 2017-04 is not expected to have a material impact on our financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016-02, “(Topic 842) Leases,” (“ASU 2016-02”). The new guidance requires the recording of assets and liabilities arising from leases on the balance sheet accompanied by enhanced qualitative and quantitative disclosures in the notes to the financial statements. ASU 2016-02 is effective for fiscal years beginning after December 31, 2018 (our fiscal year 2020), including interim periods within that reporting period. Early adoption is permitted as of the beginning of an interim or annual period. In July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases,” and ASU 2018-11, “Leases (Topic 842) Targeted Improvements,” in December 2018, the FASB issued ASU 2018-20, “Narrow-Scope Improvements for Lessors” and in March 2019, the FASB issued ASU 2019-01, “Leases (Topic 842): Codification Improvements.” These ASUs provide adjustments relating to ASU 2016-02 and improvements to comparative reporting requirements for initial adoption and for separating components of a contract for lessors. We are currently in the process of evaluating the impact of the collective standard (“ASC 842”) on our financial position, results of operations and cash flows.
