New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Pronouncements The FASB previously issued five ASUs related to financial instruments—credit losses. The ASUs issued were: (1) in June 2016, ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” (2) in November 2018, ASU 2018-19, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses,” (3) in April 2019, ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments,” (4) in May 2019, ASU 2019-05, “Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief,” and (5) in November 2019, ASU 2019-11, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses.” Additionally, in February and March 2020, the FASB issued ASU 2020-02, “Financial Instruments—Credit Losses (Topic 326)” and “Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to ASU 2016-02, Leases (Topic 842)” and ASU 2020-03, “Codification Improvements to Financial Instruments,” respectively, which include amendments to Topic 326. ASU 2016-13 is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. ASU 2018-19 clarifies that receivables arising from operating leases are not within the scope of the credit losses standard, but rather, should be accounted for in accordance with the leasing standard. ASU 2019-04 clarifies and improves areas of guidance related to the recently issued standards on financial instruments—credit losses, derivatives and hedging, and financial instruments. ASU 2019-05 provides entities that have certain instruments within the scope of Subtopic 326-20, “Financial Instruments—Credit Losses—Measured at Amortized Cost,” with an option to irrevocably elect the fair value option in Subtopic 825-10, “Financial Instruments—Overall.” ASU 2019-11 clarifies guidance around how to report expected recoveries and reinforces existing guidance that prohibits organizations from recording negative allowances for available-for-sale debt securities, among other narrow scope and technical improvements. ASU 2020-02 adds an SEC paragraph pursuant to the issuance of SEC Staff Accounting Bulletin No. 119 on loan losses to Topic 326 and also updates the SEC section of the codification for the change in the effective date of Topic 842. ASU 2020-03 makes narrow-scope improvements to various aspects of the financial instrument guidance as part of the FASB’s ongoing codification improvement project aimed at clarifying specific areas of accounting guidance to help avoid unintended application. We adopted ASU 2016-13, ASU 2018-19 (as it relates to financial instruments—credit losses), ASU 2019-05, ASU 2019-11, ASU 2020-02 and ASU 2020-03 in the first quarter of 2020 and the adoption did not have a material impact on our consolidated financial statements and related disclosures. In November 2018, the FASB issued ASU 2018‑18, “Collaborative Arrangements (Topic 808): Clarifying the Interaction Between Topic 808 and Topic 606.” This ASU provides guidance on how to assess whether certain transactions between collaborative arrangement participants should be accounted for within the revenue recognition standard and provides more comparability in the presentation of revenue for certain transactions between collaborative arrangement participants. This ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those years, with early adoption permitted. We adopted ASU 2018‑18 in the first quarter of 2020 and the adoption did not have a material impact on our consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018‑14, “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans.” This ASU makes minor changes to the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This ASU is effective for fiscal years ending after December 15, 2020, with early adoption permitted. ASU 2018-14 only revises disclosure requirements. We adopted ASU 2018‑14 in the fourth quarter of 2020 and the adoption did not have a material impact on our consolidated financial statements and related disclosures. Recent Accounting Pronouncements Pending Adoption In December 2019, the 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 are evaluating the effect that ASU 2019‑12 will have on our consolidated financial statements and related disclosures, but do not expect it to have a material impact. 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 are evaluating the effect that ASU 2020‑01 will have on our consolidated financial statements and related disclosures, but do not expect it to have a material impact. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. This ASU is effective for a limited time for all entities through December 31, 2022. We are evaluating the effect that ASU 2020-04 will have 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 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 are evaluating the effect that ASU 2020-08 will have on our consolidated financial statements and related disclosures, but do not expect it to have a material impact. 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. We are evaluating the effect that ASU 2020-09 will have on our consolidated financial statements and related disclosures, but do not expect it to have a material impact. 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 are evaluating the effect that ASU 2020-10 will have on our consolidated financial statements and related disclosures, but do not expect it to have a material impact.
