New Accounting Pronouncement or Change in Accounting Principle, Description       Codification Improvements In July 2018, the FASB issued ASU 2018-09, which includes technical corrections, clarifications, and other minor improvements to various areas including business combinations, fair value measurements and hedging. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in this standard were effective immediately, while others were effective for the Company’s fiscal year beginning January 1, 2019. The adoption of this standard did not have a material effect on our financial statements. Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU 2018-07, which simplifies the accounting for share-based arrangements with nonemployees.  The new guidance generally aligns the accounting for share-based awards to nonemployees with the guidance for share-based awards to employees.  The guidance was effective for the Company’s fiscal year beginning January 1, 2019.  The adoption of this standard did not have a material effect on our financial statements. Financial Instruments—Credit Losses In June 2016, the FASB issued ASU 2016-13, which changes the impairment model for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance applies to most financial assets measured at amortized cost, including trade and other receivables and loans as well as off-balance-sheet credit exposures (e.g., loan commitments and standby letters of credit). The standard will replace the “incurred loss” approach under the current guidance with an “expected loss” model that requires an entity to estimate its lifetime “expected credit loss.” The standard is effective for the Company’s fiscal year beginning January 1, 2020 with early adoption permitted beginning January 1, 2019. We do not expect the adoption of this guidance to have a material effect on our financial statements.

New Accounting Pronouncement or Change in Accounting Principle, Description                 In August 2017, the FASB issued ASU 2017-12, which amends the current hedge accounting model. The new standard eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item (which is consistent with our prior practice). The change in fair value for qualifying cash flow and net investment hedges is included in other comprehensive loss (until they are reclassified into the income statement). The standard also eased certain documentation and assessment requirements and modified the accounting for components excluded from the assessment of hedge effectiveness. We adopted this standard as of January 1, 2019. The adoption of this standard did not have a material effect on our financial statements.

New Accounting Pronouncement or Change in Accounting Principle, Description     Changes to the Disclosure Requirements for Defined Benefit Plans In August 2018, the FASB issued ASU 2018-14, which removes several disclosure requirements, including the amount in AOCI expected to be recognized in income over the next fiscal year and the effects of a 1% change in assumed health care cost trend rates.  The standard also adds new requirements to disclose reasons for significant gains and losses related to changes in the benefit obligation for the period and weighted-average interest crediting rates for plans with promised interest crediting rates. We adopted this guidance on January 1, 2019. The adoption of this standard did not have a material effect on our financial statements.

New Accounting Pronouncement or Change in Accounting Principle, Description     Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, which removes the requirement to disclose: 1) amount of and reasons for transfers between Levels 1 and 2 of the fair value hierarchy, 2) policy for timing of transfers between levels, and 3) valuation processes for Level 3 investments. In addition, this guidance modifies and adds other disclosure requirements, which primarily relate to valuation of Level 3 assets and liabilities. The guidance is effective for the Company’s fiscal year beginning January 1, 2020, with early adoption permitted.  We do not expect the adoption of this guidance to have a material effect on our financial statements. Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract In August 2018, the FASB issued ASU 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Costs to obtain software, including configuration and integration with legacy IT systems, coding and testing, including parallel process phases are eligible for capitalization under the new standard.  In addition, activities that would be expensed include costs related to vendor demonstrations, determining performance and technology requirements and training activities. The standard is effective for the Company’s fiscal year beginning January 1, 2020, with early adoption permitted.  We do not expect the adoption of this guidance to have a material effect on our financial statements.

New Accounting Pronouncement or Change in Accounting Principle, Description   Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, which is intended to simplify accounting for income taxes and improve consistency in application.  ASU 2019-12 amends certain elements of income tax accounting, including but not limited to intraperiod tax allocations, step-ups in tax basis of goodwill, and calculating taxes on year-to-date losses in interim periods.  The guidance is effective for the Company’s fiscal year beginning January 1, 2021, with early adoption permitted.  We are assessing the impact that the adoption of this guidance will have on our financial statements.

New Accounting Pronouncement or Change in Accounting Principle, Description Clarifications in Accounting for Equity Securities In January 2020, the FASB issued ASU 2020-01, which clarifies the interactions between accounting for equity investments (ASC 321), equity method accounting (ASC 323) and derivatives and hedges (ASC 815).  As a result of the ASU, when entities apply the measurement alternative to non-controlling equity investments under ASC 321, and must transition to the equity method of accounting because of an observable transaction, existing investments should be remeasured immediately before applying the equity method of accounting.  Additionally, it states that if entities hold non-derivative forward contracts or purchased call options to acquire equity securities, such instruments should be measured using the fair value principles of ASC 321 before settlement or exercise.  The guidance is effective for the Company’s fiscal year beginning on January 1, 2021, with early adoption permitted.  We are assessing the impact that the adoption of this guidance will have on our financial statements.
