Recent Accounting Pronouncements | Recent Accounting Pronouncements: In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 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 update 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. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted the new guidance on a prospective basis in the first quarter of fiscal 2021. The adoption of this guidance did not have a material impact on the Company’s Condensed Consolidated Financial Statements and related disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which was subsequently amended in November 2018 through ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments Credit Losses. ASU 2016-13 requires entities to estimate all expected credit losses for financial assets measured at amortized cost basis, including trade receivables, held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The Company adopted this guidance using the modified retrospective adoption method beginning with its first quarter ended November 21, 2020. The adoption of this new guidance did not have a material impact on the Company's Condensed Consolidated Financial Statements and related disclosures. The balance for allowance for uncollectable accounts was $11.2 million at February 13, 2021 and $10.0 million at August 29, 2020.
