Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The interim consolidated financial statements are unaudited but, in the opinion of management, reflect all adjustments necessary for a fair statement of the Company’s consolidated financial position, results of operations and cash flows for the periods presented. These adjustments consist of normal, recurring items. The results of operations for any interim period are not necessarily indicative of results for the full year. The interim consolidated financial statements and notes are presented as permitted by the requirements for Quarterly Reports on Form 10-Q. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s consolidated financial statements and notes included in its Annual Report on Form 10-K. In the second quarter of 2023, 3M re-consolidated the Aearo Technology and certain of its related entities (collectively, the "Aearo Entities") as a result of the court dismissal of their voluntary bankruptcy proceedings. 3M had previously deconsolidated these entities in the third quarter of 2022. See additional information in Note 14. Effective in the first quarter of 2023, 3M made changes in the measure of segment operating performance and segment composition used by 3M’s chief operating decision maker—impacting 3M’s disclosed measure of segment profit/loss (business segment operating income (loss)). Also effective in the first quarter of 2023, 3M's Consumer business segment re-aligned from four divisions to three divisions,
Earnings (Loss) Per Share | Earnings (Loss) Per Share The difference in the weighted average 3M shares outstanding for calculating basic and diluted earnings per share attributable to 3M common shareholders is a result of the dilution associated with the Company’s stock-based compensation plans. Certain options outstanding under these stock-based compensation plans were not included in the computation of diluted earnings (loss) per share attributable to 3M common shareholders because they would have had an anti-dilutive effect of 35.6 million and 36.0 million average options for the three and nine months ended September 30, 2023, respectively, and 31.7 million and 28.9 million average options for the three and nine months ended September 30, 2022, respectively. In periods of net losses, these anti-dilutive effects include all weighted option shares outstanding and weighted average shares is the same for the calculations of both basic and diluted loss per share. The computations for basic and diluted earnings (loss) per share follow:
Supplier Finance Program Obligations | Supplier Finance Program Obligations Under supplier finance programs, 3M agrees to pay participating banks the stated amount of confirmed invoices from its designated suppliers on the original maturity dates of the invoices, generally within 90 days of the invoice date. 3M or the banks may terminate the agreements with advance notice. Separately, the banks may have arrangements with the suppliers that provide them the option to request early payment from the banks for invoices confirmed by 3M. 3M's outstanding balances of confirmed invoices in the programs as of September 30, 2023 and December 31, 2022 were approximately $320 million and $260 million, respectively. These amounts are included within accounts payable on 3M's consolidated balance sheet.
New Accounting Pronouncements | New Accounting Pronouncements Refer to Note 1 to the Consolidated Financial Statements in 3M’s 2022 Annual Report on Form 10-K for a discussion of applicable standards issued and not yet adopted by 3M.
Business Segments | 3M’s businesses are organized, managed and internally grouped into segments based on differences in markets, products, technologies and services. 3M manages its operations in four business segments: Safety and Industrial; Transportation and Electronics; Health Care; and Consumer. 3M’s four business segments bring together common or related 3M technologies, enhancing the development of innovative products and services and providing for efficient sharing of business resources. In July 2022, 3M announced its intention to spin off the Health Care business as a separate public company (see Note 3 for additional information). 3M is an integrated enterprise characterized by substantial intersegment cooperation, cost allocations and inventory transfers. Therefore, management does not represent that these segments, if operated independently, would report the operating income information shown. 3M discloses business segment operating income (loss) as its measure of segment profit/loss, reconciled to both total 3M operating income (loss) and income before taxes. Business segment operating income (loss) excludes certain expenses and income that are not allocated to business segments (as described below in “Corporate and Unallocated”). Effective in the first quarter of 2023, the measure of segment operating performance and segment composition used by 3M’s chief operating decision maker (CODM) changed and, as a result, 3M’s disclosed measure of segment profit/loss (business segment operating income (loss)) was updated. The change to business segment operating income (loss) aligns with the update to how the CODM assesses performance and allocates resources for the Company’s business segments. The changes included the items described below. The financial information presented herein reflects the impact of these business segment reporting changes for all periods presented. Reflecting gains/losses from sale of property, plant and equipment (PPE) and other assets within Corporate and Unallocated Change 3M updated its business segment operating performance measure to reflect all gains/losses from sales of PPE and other assets within Corporate and Unallocated. Previously, certain of these gains/losses were included in 3M’s business segments’ operating performance. Movement of certain businesses between segments The businesses associated with two groups of products (each with approximately $25 million in annual sales) were realigned with one moving from the Consumer business segment to the Health Care business segment and the other moving from the Health Care business segment to the Consumer business segment. Also effective in the first quarter of 2023, the Consumer business segment re-aligned from four divisions to the following three divisions: Home, Health and Auto Care; Construction and Home Improvement Markets; and Stationery and Office. Corporate and Unallocated Corporate and Unallocated operating income (loss) includes “corporate special items” and “other corporate expense-net”. Corporate special items include net costs for significant litigation impacting operating income (loss) associated with PFAS-related other environmental and Combat Arms Earplugs matters. In addition, during the voluntary chapter 11 bankruptcy period (which began in July 2022 and ended in June 2023—see Note 14), costs associated with the Aearo portion of respirator mask/asbestos matters were also included in corporate special items. Prior to the bankruptcy, costs associated with Combat Arms Earplugs matters were not included in the Corporate net costs for significant litigation special item, instead being reflected in the Safety and Industrial business segment. Corporate special items also include divestiture costs, gain/loss on business divestitures (see Note 3), divestiture-related restructuring costs (see Note 5), and Russia exit costs/ benefits (see Note 13). Divestiture costs include costs related to separating and divesting substantially an entire business segment of 3M following public announcement of its intended divestiture. Other corporate expense-net includes items such as net costs related to limited unallocated corporate staff and centrally managed material resource centers of expertise costs, corporate philanthropic activity, gains/losses from sales of PPE and other assets, and other net costs that 3M may choose not to allocate directly to its business segments. Other corporate expense-net also includes costs and income from transition supply, manufacturing, and service arrangements with Neogen Corporation following the 2022 split-off of 3M's Food Safety business. Items classified as revenue from this activity are included in Corporate and Unallocated net sales. Because Corporate and Unallocated includes a variety of miscellaneous items, it is subject to fluctuation on a quarterly and annual basis.
