Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements of Newell Brands Inc. (collectively with its subsidiaries, the “Company”) have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) and do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements include all adjustments (including normal recurring accruals) considered necessary for a fair statement of the financial position and the results of operations of the Company. These unaudited condensed consolidated financial statements should be read in conjunction with the financial statements, and the footnotes thereto, included in the Company’s most recent Annual Report on Form 10-K. The Condensed Consolidated Balance Sheet at December 31, 2021 has been derived from the audited financial statements as of that date, but it does not include all the information and footnotes required by U.S. GAAP for a complete financial statement. Certain reclassifications have been made in the Company's financial statements of the prior year to conform to current year presentation. On March 31, 2022, the Company sold its Connected Home & Security (“CH&S”) business unit to Resideo Technologies, Inc. See Footnotes 2 and 16 for further information. Use of Estimates and Risks Management’s application of U.S. GAAP in preparing the Company's consolidated financial statements requires the pervasive use of estimates and assumptions. The Company continues to be impacted by the COVID-19 pandemic, inflationary and supply chain pressures, and the indirect macroeconomic impact of the Russia-Ukraine conflict, which has required greater use of estimates and assumptions in the preparation of the consolidated financial statements, more specifically, those estimates and assumptions utilized in the Company’s forecasted results of operations and cash flows that form the basis in developing the fair values utilized in its impairment assessments, its annual effective tax rate and other related reserves. These estimates also include assumptions as to the timing and amount of demand shifts amongst sales channels, workforce availability and supply chain continuity. Although management has made its best estimates and assumptions based upon current information, actual results could materially differ and may require future changes to such estimates and assumptions, including reserves, which may result in future expense. Seasonal Variations Sales of the Company’s products tend to be seasonal, with sales, operating income and operating cash flow in the first quarter generally lower than any other quarter during the year, driven principally by reduced volume and the mix of products sold in the first quarter. The seasonality of the Company’s sales volume combined with the accounting for fixed costs, such as depreciation, amortization, rent, personnel costs and interest expense, impacts the Company’s results on a quarterly basis. In addition, the Company typically tends to generate the majority of its operating cash flow in the third and fourth quarters of the year due to seasonal variations in operating results, the timing of annual performance-based compensation payments, customer program payments, working capital requirements and credit terms provided to customers. Accordingly, the Company’s results of operations for the three and six months ended June 30, 2022 and cash flows for the six months ended June 30, 2022, may not necessarily be indicative of the results that may be expected for the year ending December 31, 2022. The Company's sales and operating results, previously disrupted by the COVID-19 pandemic, reverted back to historical patterns in 2021, however, uncertainty still remains due to the inflationary and supply chain pressures and the volatility and direction of future consumer demand patterns. Recent Accounting Pronouncements Changes to U.S. GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” In January 2021, the FASB clarified the scope of this guidance with the issuance of ASU 2021-01, Reference Rate Reform: Scope. ASU 2020-04 provides optional expedients and exceptions to account for contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate if certain criteria are met. ASU 2020-04 may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is currently evaluating the potential effects of the adoption of ASU 2020-04. Sales of Accounts Receivables Factored receivables at June 30, 2022 associated with the Company's existing factoring agreement (the “Customer Receivables Purchase Agreement”) were approximately $545 million, an increase of approximately $45 million from December 31, 2021. During the second quarter of 2022, the Company amended the Customer Receivables Purchase Agreement to (1) increase the amount of certain customer receivables that may be sold under the agreement, (2) add new customers to the agreement and (3) change the reference rate from LIBOR to Secured Overnight Financing Rate (“SOFR”). Transactions under this agreement are accounted for as sales of accounts receivable, and the receivables sold are removed from the Condensed Consolidated Balance Sheet at the time of the sales transaction. The Company classifies the proceeds received from the sales of accounts receivable as an operating cash flow in the Condensed Consolidated Statement of Cash Flows. The Company records the discount as other (income) expense, net in the Condensed Consolidated Statement of Operations and collections of accounts receivables not yet submitted to the financial institution as a financing cash flow.
