The amendments in this ASU provide clarifications which align 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 or software licenses.

The guidance removed the requirements of the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels and the valuation process for Level 3 fair value measurements. This ASU also added additional requirements regarding changes in unrealized gains and losses for the period included in other comprehensive (loss) income for recurring Level 3 fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. We have evaluated and adopted this guidance effective January 1, 2020. The adoption did not significantly impact the presentation of our financial condition, results of operations and disclosures. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU require a financial asset measured at amortized cost basis to be presented at the net amount expected to be collected and credit losses relating to available-for-sale debt securities to be recorded through an allowance for credit losses. The standard replaces today’s “incurred loss” approach with an “expected loss” model for instruments measured at amortized cost. We completed the assessment of our evaluation of the new standard on our accounting policies and adopted this guidance effective January 1, 2020 using a modified retrospective approach without restating prior comparative periods. The adoption of this guidance did not significantly impact the presentation of our financial condition, results of operations and disclosures. Recent accounting guidance not yet adopted In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing the following exceptions: the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items, the exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, the exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary and the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments in this ASU also simplify the accounting for income taxes by requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax, requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the goodwill recorded for US GAAP purposes was originally recognized and when it should be considered a separate transaction, specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements with some exceptions, requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date and making minor codification improvements for income taxes related to employee stock ownership plans. For all public business entities, ASU 2019-12 is effective for annual periods and interim periods beginning after December 15, 2020; early adoption is permitted for public organizations for which financial statements have not yet been issued. We are currently evaluating this guidance and the impact on the presentation of our financial condition, results of operations and disclosures.
