Accounting Changes and Error Corrections [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Pronouncements Lease Accounting. In February 2016, the Financial Accounting Standards Board (“FASB”) issued authoritative guidance which changes financial reporting as it relates to leasing transactions. Under the new guidance, lessees are required to recognize a lease liability, measured on a discounted basis; and a right-of-use asset, for the lease term. The Company adopted this guidance as of January 1, 2019, using the transition method that allowed it to initially apply the guidance as of the adoption date. The Company elected the package of practical expedients available under the new standard, which allowed the Company to forgo a reassessment of (1) whether any expired or existing contracts are or contain leases, (2) the lease classification for any expired or existing leases, and (3) the initial direct costs for any existing leases. The adoption of this guidance had a material impact on the Company’s Condensed Consolidated Statement of Financial Position beginning January 1, 2019. Prior periods were not restated. See Note G for further discussion of leases. Internal-use Software—Cloud Computing. In August 2018, the FASB issued authoritative guidance which aligns 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. Entities are required to present the expense related to capitalized implementation costs in the same line item in the statement of operations as the fees associated with the hosting elements of the arrangement and classify the payments for the capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element. Entities are also required to present the capitalized implementation costs in the statement of financial position in the same line item that a prepayment of the fees of the associated hosting arrangement would be presented. The new guidance is effective for annual and interim periods beginning after December 15, 2019, although early adoption is permitted. The Company has adopted the new guidance prospectively as of January 1, 2019, and the impact of adoption was not material to its financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted Current Expected Credit Losses Model. In June 2016, the FASB issued authoritative guidance amending how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance requires the application of a current expected credit loss model, which is a new impairment model based on expected losses. The new guidance is effective for interim and annual reporting periods beginning after December 15, 2019, with early adoption permitted for annual reporting periods beginning after December 15, 2018. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures. Simplifying the Test for Goodwill Impairment. In January 2017, the FASB issued authoritative guidance to simplify the goodwill impairment testing process. The new standard eliminates Step 2 of the goodwill impairment test. If a company determines in Step 1 of the goodwill impairment test that the carrying value of goodwill is greater than the fair value, an impairment in that amount should be recorded to the income statement, rather than proceeding to Step 2. The new guidance is effective for the Company for fiscal years beginning after December 15, 2019, although early adoption is permitted. The Company believes the adoption of this guidance will not have a material impact on its financial statements.
