Basis Of Presentation [Abstract]
New Accounting Standards	New Accounting Standards Recently Adopted In August 2020 the FASB issued ASC Update No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2020-06”). The update simplifies the accounting for convertible instruments by eliminating two accounting models (i.e., the cash conversion model and beneficial conversion feature mode) and reducing the number of embedded conversion features that could be recognized separately from the host contract. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. On January 1, 2021, we adopted ASU 2020-06 using the modified retrospective approach and recorded $20.4 million to increase long-term debt, $3.2 million to reduce retained earnings, and $16.4 million to reduce additional paid-in capital included on the Condensed Consolidated Balance Sheets. See Note 10 for further discussion of convertible debt. In December 2019 the FASB issued ASC Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”). The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments are effective for public entities in fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We adopted ASU 2019-02 on January 1, 2021 and the adoption did not have an impact on our financial condition or results of operation.
