Accounting Policies [Abstract]
Basis Of Presentation	Basis of PresentationThe interim condensed consolidated financial statements are unaudited; however, in the opinion of management, they have been prepared in accordance with Rule 10-01 of Regulation S-X and in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The December 31, 2019 financial position data included herein was derived from the audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 ("Annual Report on Form 10-K"), filed on February 21, 2020, but does not include all disclosures required by GAAP in audited financial statements. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the accompanying notes, contained in our Annual Report on Form 10-K.The unaudited condensed consolidated financial statements reflect all adjustments (all of which are of a normal, recurring nature) which management considers necessary for a fair statement of financial position, results of operations, comprehensive income and cash flows for the interim periods presented. The results for the interim periods are not necessarily indicative of results which may be expected for any other interim period or for the full year.
New Accounting Standards	New Accounting Standards Recently Adopted Accounting Standards In January 2017, the Financial Accounting Standards Board ("FASB") issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350). This guidance was issued to simplify the accounting for goodwill impairment. The guidance removes the second step of the goodwill impairment test, which requires that a hypothetical purchase price allocation be performed to determine the amount of impairment, if any. Under this new guidance, a goodwill impairment charge will be based on the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This ASU No. 2017-04 is effective beginning January 1, 2020 with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company adopted ASU No. 2017-04 on January 1, 2020, with no impact to our financial position, results of operations or cash flows. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments–Credit Losses (Topic 326), which introduces the Current Expected Credit Losses ("CECL") accounting model. CECL requires earlier recognition of credit losses, while also providing additional transparency about credit risk. CECL utilizes a lifetime expected credit loss measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. The expected credit losses are adjusted each period for changes in expected lifetime credit losses. ASU No. 2016-13 was effective for the Company on January 1, 2020. The adoption of ASU No. 2016-13 resulted in a cumulative-effect adjustment of $2.0 million included as an adjustment to accounts receivable reserve and to retained earnings on January 1, 2020. Accounting Standards Not Yet Adopted In March 2020, the FASB issued ASU No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). This pronouncement contains optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform. ASU 2020-04 is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. ASU 2020-04 can be elected for both interim and annual periods from March 12, 2020 through December 31, 2022. We plan to adopt ASU 2020-04 as of January 1, 2021. The adoption of ASU 2020-04 is not expected to have a material impact on our financial position, results of operations or cash flows. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 is intended to improve consistent application of Topic 740 and simplify the accounting for income taxes. This pronouncement removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance. ASU 2019-12 is effective for annual and interim reporting periods beginning after December 12, 2020, with early adoption permitted. The Company is currently evaluating the effects of this on our financial position, results of operations or cash flows.
