Condensed Consolidated Financial Statements [Abstract]
Recent Accounting Pronouncements Adopted and Not Yet Adopted	Recent Accounting Pronouncements Adopted Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued accounting guidance which clarifies the principles for recognizing revenue and provides a comprehensive model for revenue recognition. Revenue recognition should depict the transfer of goods or services to a customer at an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The guidance also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. This accounting guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company adopted this accounting guidance using the modified retrospective transition method. The adoption of this accounting guidance in the first quarter of 2019 did not have a material effect on the Company’s consolidated financial position or results of operations, and the Company did not record a cumulative catch-up adjustment to the opening balance of retained earnings. See Note 8 for further discussion on revenue recognition accounting policies and related disclosures. Recognition of Breakage for Certain Prepaid Stored-Value Products In March 2016, in order to address diversity in practice related to the derecognition of a prepaid stored-value product liability, the FASB issued accounting guidance requiring breakage for prepaid stored-value product liabilities to be accounted for consistent with the breakage guidance in the revenue recognition standard (see “Revenue Recognition” above). This accounting guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. This accounting guidance may be applied either on a modified retrospective basis or on a retrospective basis. The Company adopted this accounting guidance using the modified retrospective transition method. The adoption of this accounting guidance in the first quarter of 2019 did not have a significant impact on the Company’s consolidated financial position or results of operations, and the Company did not record a cumulative catch-up adjustment to the opening balance of retained earnings. Modification of Share-Based Payment Awards In May 2017, the FASB issued accounting guidance to provide clarity, reduce the diversity in practice and to simplify the accounting guidance related to a change to the terms or conditions of a share-based payment award. This new standard provides guidance for evaluating which changes to the terms or conditions of a share-based payment award are substantive and require modification accounting to be applied. This accounting guidance is effective for fiscal periods beginning after December 15, 2017, and interim periods within those fiscal years on a prospective basis. The adoption of this accounting guidance in the first quarter of 2019 did not have a significant impact on the Company’s consolidated financial position or results of operations. Recent Accounting Pronouncements Not Yet Adopted Leases In February 2016, the FASB issued accounting guidance which requires the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements.

The Company is in the process of implementing software to assist in the quantification of the impact on the Company’s consolidated financial position and results of operations related to the adoption of this accounting guidance in the first quarter of 2020. Accounting for Hedging Activities In August 2017, the FASB issued accounting guidance which amends the recognition, presentation and disclosure requirements of hedge accounting in order to better portray the economics of entities’ risk management activities, increase transparency and understandability of hedging relationships and simplify the application of hedge accounting. This accounting guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early application is permitted. The recognition requirements for cash flow and net investment hedges existing at the date of adoption will be applied using a cumulative-effect adjustment to retained earnings. The amended presentation and disclosure requirements will be applied on a prospective basis. The Company is currently evaluating the impact of adopting this accounting guidance in the first quarter of 2020. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income On December 22, 2017, the U.S. government enacted P.L. 115-97, the Tax Cuts and Jobs Act (the “Tax Act”).

This accounting guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. If elected, this accounting guidance should be applied either in the period of adoption or retrospectively to each period in which the change in the U.S. federal corporate rate in the Tax Act is recognized. Early application is permitted. The Company is currently evaluating the impact of adopting this accounting guidance in the first quarter of 2020. Share-Based Payment Arrangements With Nonemployees In June 2018, the FASB issued accounting guidance in order to simplify accounting for share-based payments granted to nonemployees for goods and services. This new guidance aligns most of the accounting requirements for share-based payments granted to nonemployees with the existing guidance for share-based payments granted to employees. This accounting guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, using a modified retrospective transition approach. Early adoption is permitted. The Company does not expect that the adoption of this accounting guidance in the first quarter of 2020 will have a significant impact on the Company’s consolidated financial position or results of operations.
