New Accounting Standards	New Accounting Standards On December 18, 2019, the FASB issued Accounting Standard Update (ASU) 2019-12: Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. Also, the amendments simplify the accounting for income taxes by requiring the following: (1) that an entity recognize a franchise tax that is partially based on income in accordance with Topic 740 and account for any incremental amount incurred as a non-income-based tax; and (2) 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 included the enactment date. For public companies, these amendments are effective for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. We are currently evaluating the impact the adoption of this guidance may have on the Company’s condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-2, “Leases.” This guidance establishes a ROU model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company adopted this standard effective May 1, 2019. See Note H for a discussion of the impact of adoption of this standard. In August 2018, the Commission adopted final rules pursuant to Commission Release No. 33-10532, “Disclosure Update and Simplification,” amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements relating to the analysis of stockholders’ equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders’ equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of income is required to be filed. This final rule became effective on November 5, 2018. The Company adopted this final rule effective for the second quarter of fiscal 2019. The adoption of this standard did not have a significant impact on the Company’s consolidated financial position or results of operations. In February 2018, the FASB issued ASU 2018-2, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This guidance provides the Company with an option to reclassify stranded tax effects resulting from the Tax Cuts and Jobs Act (the "2017 Tax Act") from accumulated other comprehensive income to retained earnings. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company adopted this standard effective May 1, 2019 and did not elect to reclassify tax effects as a result of tax reform; therefore, the adoption did not have a significant impact on the Company’s consolidated financial position or results of operations. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” which replaces the current incurred loss method used for determining credit losses on financial assets, including trade receivables, with an expected credit loss method. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2022. The Company will adopt this standard in fiscal year 2024. The Company does not expect the adoption of this standard to have a significant impact on the Company’s consolidated financial position or results of operations.
