New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	3. RECENT ACCOUNTING PRONOUNCEMENTS Recent accounting guidance adopted in 2019 In February 2018, the FASB issued ASU No. 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this ASU provide financial statement preparers with an option to reclassify stranded tax effects within accumulated other comprehensive income (“AOCI”) to retained earnings in each period when the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recorded. For all entities, ASU 2018-02 is effective for annual periods and interim periods beginning after December 15, 2018. We have evaluated and adopted this guidance beginning 2019. The adoption did not significantly impact the presentation of our financial condition, results of operations and disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The objective of Topic 842 is to establish transparency and comparability that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. The core principle of Topic 842 is that lessees should recognize the assets and liabilities that arise from leases. All leases create an asset and liability for the lessee in accordance with FASB Concept Statements No. 6 Elements of Financial Statements, and, therefore, recognition of those lease assets and liabilities represents an improvement over previous GAAP. The accounting applied for lessors largely remained unchanged. The amendment in this ASU requires recognition of a lease liability and a right of use asset at the lease inception date. For all public business entities, ASU 2016-02 is effective for annual periods and interim periods beginning after December 15, 2018. We completed the assessment of our evaluation of the new standard on our accounting policies and processes and adopted this guidance beginning 2019 using a modified retrospective approach without restating prior comparative periods. The most significant impact primarily relates to our accounting for real estate leases and real estate subleases. The adoption of this guidance significantly impacts the presentation of our financial condition and disclosures, but didn’t materially impact our results of operations. See Note 7 “Leases” for further information. Recent accounting guidance not yet adopted In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. 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 accounting for the service element of a hosting arrangement that is a service contract is not affected by these amendments. For public entities, ASU 2018-15 is effective for annual periods and interim periods beginning after December 15, 2019; early adoption is permitted. We are currently evaluating this guidance and believe the adoption will not significantly impact the presentation of our financial condition, results of operations and disclosures. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU include removals, modifications of and additions to the disclosure requirements on fair value measurements, including the consideration of costs and benefits. 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. The modifications include requirements to disclose timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse if the investee has communicated the timing to the entity or announced the timing publicly for those investments in entities which calculate net asset value as well as provides clarity for disclosures surrounding uncertainties in measurement as of the reporting date. Furthermore, this ASU added additional requirements regarding changes in unrealized gains and losses for the period included in other comprehensive 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. For all entities, ASU 2018-13 is effective for annual periods and interim periods beginning after December 15, 2019; early adoption is permitted. We are currently evaluating this guidance and believe the adoption will 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. Furthermore, in May 2019, the FASB issued ASU No. 2019-05, providing targeted transition relief to provide 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, applied on an instrument-by-instrument basis for eligible instruments, upon adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. For all public business entities, ASU 2016-13 is effective for annual periods and interim periods beginning after December 15, 2019; early adoption is permitted for all organizations for annual periods and interim periods beginning after December 15, 2018. We are currently evaluating this guidance and believe the adoption will not significantly impact the presentation of our financial condition, results of operations and disclosures.
