New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Adopted and New Accounting Standards	Recently Adopted and New Accounting Standards RECENTLY ADOPTED On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842), and subsequent ASUs related to Topic 842. The new guidance increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The adoption of Topic 842 had a material impact on our Consolidated Balance Sheet due to the recognition of right-of-use (ROU) assets of approximately $85 million and lease liabilities of approximately $90 million as of January 1, 2019. The difference between these lease assets and lease liabilities represents deferred rent balances that were reclassified on the balance sheet. The adoption of Topic 842 did not have a material impact on our Consolidated Statement of Operations or our Consolidated Statement of Cash Flows. We will continue to report periods prior to January 1, 2019 under prior guidance as outlined in Accounting Standards Codification Topic 840, "Leases." See Note 4, "Leases" for further discussion. NEW ACCOUNTING STANDARDS In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40). This ASU requires capitalization of certain implementation costs incurred in a cloud computing arrangement that is a service contract. This ASU is effective for fiscal years beginning after December 15, 2019 and for interim periods therein. We do not believe this ASU will have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20), which modifies the disclosure requirements for defined benefit and other postretirement plans. This ASU eliminates certain disclosures associated with accumulated other comprehensive income, plan assets, related parties and the effects of interest rate basis point changes on assumed health care costs, with other disclosures being added to address significant gains and losses related to changes in benefit obligations. This ASU also clarifies disclosure requirements for projected benefit and accumulated benefit obligations. The amendments in this ASU are effective for fiscal years ending after December 15, 2020, with early adoption permitted and adoption on a retrospective basis for all periods presented required. We do not believe it will have a material impact on our consolidated financial statements beyond updating footnote disclosures. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 326), which modifies the measurement approach for credit losses on financial assets measured on an amortized cost basis from an 'incurred loss' method to an 'expected loss' method. Such modification of the measurement approach for credit losses eliminates the requirement that a credit loss be considered probable, or incurred, to impact the valuation of a financial asset measured on an amortized cost basis. The amended guidance requires the measurement of expected credit losses to be based on relevant information, including historical experience, current conditions, and a reasonable and supportable forecast that affects the collectability of the related financial asset. This amendment will affect trade receivables, off-balance sheet credit exposures and any other financial assets not excluded from the scope of this amendment that have the contractual right to receive cash. The new standard is effective for annual and interim periods beginning after December 15, 2019. We do not believe this ASU will have a material impact on our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which removes certain exceptions, such as the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year, and simplifies the accounting for income taxes in areas such as franchise tax (or similar tax) that is partially based on income. The new standard is effective for annual and interim periods beginning after December 15, 2020, with early adoption permitted, including adoption in any interim period. We do not believe this ASU will have a material impact on our consolidated financial statements. We reviewed all other new accounting pronouncements issued in the period and concluded that they are not applicable to our business.
