Accounting Policies [Abstract]
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 2020-10, “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 Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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. In July 2021, the FASB issued ASU 2021-05, “Leases (Topic 842): Lessors-Certain Leases with Variable Lease Payments (Topic 842).” The ASU amends the lease classification requirements for lessors to align them with practice under Topic 840. Lessors should classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if certain criteria are met. This guidance is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. We are evaluating the effect that ASU 2021-05 will have on our consolidated financial statements and related disclosures, but do not expect it to have a material impact. In October 2021, the FASB issued ASU 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers.” This ASU requires that an acquirer entity in a business combination recognize and measure contract assets and liabilities acquired in a business combination at the acquisition date in accordance with Topic 606 as if the acquirer entity had originated the contracts. This ASU is effective for fiscal years beginning after December 15, 2022, and interim periods within those years. Early application of the amendments is permitted but should be applied to all acquisitions occurring in the annual period of adoption. The amendment should be applied prospectively to business combinations occurring on or after the effective date of the amendments. We are evaluating the effect that ASU 2021-08 will have on our consolidated financial statements and related disclosures, but do not expect it to have a material impact. In November 2021, the FASB issued ASU 2021-10, “Disclosures by Business Entities about Government Assistance.” This ASU requires annual disclosures that increase the transparency of transactions with a government accounted for by applying a grant or contribution accounting model by analogy, including (1) the types of transactions, (2) the accounting for those transactions, and (3) the effect of those transactions on an entity’s financial statements. This ASU is effective for fiscal years beginning after December 15, 2021. Early application is permitted. The amendments should be applied either (1) prospectively to all transactions within the scope of the amendments that are reflected in financial statements at the date of initial application and new transactions that are entered into after the date of initial application or (2) retrospectively to those transactions. We are evaluating the effect that ASU 2021-10 will have on our consolidated financial statements and related disclosures, but do not expect it to have a material impact.
