The following table summarizes recent ASU's issued by the Financial Accounting Standards Board (“FASB”) which have been assessed:


Standard	Description	Effective Date	Effect on Financial Statements or Other Significant Matters
ASU 2020-04 Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting	This update provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate (LIBOR) reform on financial reporting.	March 12, 2020 (Fiscal 2020) through December 31, 2022 (Fiscal 2023)	The Company is assessing the effects of the Reference Rate Reform. The Company has not yet determined the impact of this ASU on its consolidated results of operations, financial condition, or cash flows.
ASU 2018-14 Compensation-Retirement Benefits-Defined Benefit Plans	This update modifies the disclosure requirements for employers that sponsor defined benefit pension or other post-retirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year, and (b) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for post-retirement health care benefits. Additional disclosures include descriptions of significant gains and losses affecting the benefit obligation for the period. The amendments in ASU 2018-14 would need to be applied on a retrospective basis.	July 1, 2021 (Fiscal 2022)	The adoption of this guidance will modify disclosures but will not have an impact on the Company's consolidated results of operations, financial condition, or cash flows.
ASU 2018-13 Fair Value Measurement	This update modifies the disclosure requirements on fair value measurements. Certain disclosures in ASU 2018-13 would need to be applied on a retrospective basis and others on a prospective basis.	July 1, 2020 (Fiscal 2021)	The adoption of this guidance will modify disclosures but will not have an impact on the Company's consolidated results of operations, financial condition, or cash flows.


ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	This update introduces the current expected credit loss (CECL) model, which will require an entity to measure credit losses for certain financial instruments and financial assets, including trade receivables. Under this update, on initial recognition and at each reporting period, an entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the financial instrument. In addition, this update modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. In November 2019, the FASB issued Accounting Standard Update 2019-11 Codification Improvements to Topic 326, Financial-Credit Losses which provides clarification and eliminates inconsistencies to amendments included in Update 2016-13.	July 1, 2020 (Fiscal 2021)	Upon adoption of the CECL standard, in fiscal 2021, the Company intends to book an immaterial cumulative-effect adjustment to retained earnings. The most notable impact relates to the newly implemented processes around the assessment of the adequacy of our allowance for doubtful accounts on accounts receivable. The adoption of this guidance will not have a material impact on the Company's consolidated results of operations, financial condition, or cash flows.
