Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (FASB) issued ASU 2019‑12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” This ASU removes specific exceptions to the general principles in Topic 740 and improves and simplifies financial statement preparers’ application of income tax-related guidance. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those years, with early adoption permitted. We adopted ASU 2019‑12 in the first quarter of 2021 and the adoption did not have a material impact on our consolidated financial statements and related disclosures. In January 2020, the FASB issued ASU 2020‑01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815).” This ASU, among other things, clarifies that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323 and clarifies that, when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those years, with early adoption permitted. We adopted ASU 2020‑01 in the first quarter of 2021 and the adoption did not have a material impact on our consolidated financial statements and related disclosures. In October 2020, the FASB issued ASU 2020-08, “Codification Improvements to Subtopic 310-20, Receivables — Nonrefundable Fees and Other Costs.” This ASU states that an entity should reevaluate whether a callable debt security is within the scope of the Accounting Standards Codification (ASC) 310-20-35-33 for each reporting period. The ASU is not expected to have a significant effect on current practice or create a large administrative cost for most entities. The amendments stated in this ASU are intended to make ASC 310-20 easier to understand and apply. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those years. Early application is not permitted. We adopted ASU 2020-08 in the first quarter of 2021 and the adoption did not have a material impact on our consolidated financial statements and related disclosures. In October 2020, the FASB issued ASU 2020-09, “Debt (Topic 470): Amendments to SEC Paragraphs Pursuant to SEC Release No. 33-10762.” This ASU aligns the SEC paragraphs in the codification with the new SEC rules issued in March 2020 relating to changes to the disclosure requirements for certain debt securities. Certain glossary terms were superseded, and amendments were made to debt and other topics as a result of this update. On March 2, 2020, the SEC issued Release No. 33-10762, which made significant changes to its disclosure requirements relating to certain debt securities. The new rules impact disclosures related to registered securities that are guaranteed and those that are collateralized by the securities of an affiliate. The final rules became effective on January 4, 2021. Voluntary compliance with the final amendments in advance of January 4, 2021 is permitted, hence we elected early compliance with the new rules. Because the amendments made by the FASB in this ASU are to ensure alignment of the relevant SEC paragraphs in ASC 270, ASC 460, ASC 470 and ASC 505 with the amended rules in Release No. 33-10762, the amendments made by the FASB to these SEC paragraphs will not have a material impact on our disclosures, since we already elected early compliance with the amended rules in Release No. 33-10762. In October 2020, the FASB issued ASU 2020-10, “Codification Improvements.” This ASU is intended to conform, clarify, simplify, and/or provide technical corrections to a wide variety of codification topics, including moving certain presentation and disclosure guidance to the appropriate codification section. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those years. Early application of the amendments is permitted for and varies based on the entity. The amendments should be applied retrospectively and at the beginning of the period that includes the adoption date. We adopted ASU 2020-10 in the first quarter of 2021 and the adoption did not have a material impact on our consolidated financial statements and related disclosures. Recent Accounting Pronouncements Pending Adoption In March 2020 and January 2021, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" and ASU 2021-01, "Reference Rate Reform: Scope", respectively. Together, the ASUs provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. This guidance is effective for a limited time for all entities through December 31, 2022. We are evaluating the effect that this guidance will have on our consolidated financial statements and related disclosures.
