Organization, Consolidation and Presentation of Financial Statements [Abstract]
Goodwill	Goodwill Goodwill is recorded when the cost of acquired businesses exceeds the fair value of the identifiable net assets acquired. Goodwill has an indefinite useful life and is not amortized, but is assessed for impairment annually or when events or changes in circumstances indicate that a potential impairment exists.
Other Intangible Assets	Other Assets The long-term portion of intangible assets and intangible assets with indefinite lives are included within other assets. Intangible assets with finite useful lives are amortized over their respective estimated useful lives to their estimated residual values.
Recent Accounting Pronouncements	Recent Accounting Pronouncements We consider the applicability and impact of all accounting standard updates (“ASUs”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. Adopted In February 2016, the FASB issued accounting guidance Accounting Standard Codification (“ASC”) 842 which amends ASC 840 the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. Additionally, ASC 842 requires a modified retrospective transition approach for all leases existing at, or entered into after the date of initial application, with an option to use certain transition relief. The guidance was updated in March 2018 to include an amendment that would allow us to consider the beginning of the period of adoption as the effective date of initial application of the standard. We implemented this accounting standard with an effective date of April 1, 2019. Based on the FASB transition guidance, we do not have to apply the disclosure requirement to periods prior to adoption. We elected the package of practical expedients to not re-evaluate existing lease contracts or lease classifications and therefore will not make changes to those leases already recognized on the consolidated balance sheet under ASC 840 until the leases are fully amortized, amended, or modified. In addition, we did not reassess initial direct costs for any existing leases and elected the short-term lease exception provided for in the standard and therefore will only recognize right-of-use assets and lease liabilities for leases with a term greater than one year. We elected the practical expedient to not separate lease and non-lease components for all asset classes. We completed a system implementation and have updated our accounting policies to meet the standard’s requirements. On April 1, 2019, our adoption of this accounting standard resulted in recording on our condensed consolidated balance sheet right-of-use assets of $281.0 million and an increase in lease liabilities of $285.3 million with no material impact on our consolidated statements of operations and consolidated statements of cash flows. For further information on leases, see Note 9. In February 2018, the FASB issued new accounting guidance on income statement reporting of comprehensive income, specifically pertaining to reclassification of certain tax effects from accumulated other comprehensive income to retained earnings. This pronouncement is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2018, with early adoption permitted. We adopted this accounting guidance on April 1, 2019. We did not elect to reclassify certain tax effects from accumulated other comprehensive income to retained earnings. In June 2018, the FASB issued an amendment to the accounting guidance related to accounting for employee share-based payments which clarifies that an entity should recognize excess tax benefits in the period in which the amount of the deduction is determined. This amendment is effective for annual periods beginning after December 15, 2018, and is applied prospectively to changes in terms or conditions of awards occurring on or after the adoption date. We adopted this accounting guidance on April 1, 2019 with no impact to our financial statements. Not Yet Adopted In August 2018, the FASB modified the disclosure requirements on fair value measurements. The amendment modifies, removes, and adds several disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The amendment is effective for fiscal years ending after December 15, 2021 for public business entities and early adoption is permitted. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our disclosure requirements. In August 2018, the FASB modified disclosure requirements for employers that sponsor defined benefit pension plans. Certain disclosure requirements were removed and certain disclosure requirements were added. The amendment also clarifies disclosure requirements for projected benefit obligation and accumulated benefit obligation in excess of respective plan assets. The amendment is effective beginning in our fiscal year 2021 financial statements and early adoption is permitted. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our disclosure requirements. In August 2018, the FASB issued new accounting guidance that addresses the accounting for implementation costs associated with a hosted service. The guidance provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. The amendment is effective beginning in our fiscal year 2021 financial statements and early adoption is permitted. The guidance will be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements. In October 2018, the FASB amended the guidance for determining whether a decision-making fee is a variable interest. The amendments require organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in generally accepted accounting principles). Therefore, these amendments likely will result in more decision makers not consolidating VIEs. This amendment is effective beginning in our fiscal year 2021 financial statements and early adoption is permitted. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our disclosure requirements.
