Fair Value Disclosures [Abstract] |
Fair Value Measurements | NOTE 18. Fair Value Measurements Assets and Liabilities that are Measured at Fair Value on a Recurring Basis: For 3M, assets and liabilities that are measured at fair value on a recurring basis primarily relate to available-for-sale marketable securities, Solventum common stock and derivative instruments. The information in the following paragraphs and tables primarily addresses matters relative to these financial assets and liabilities. Separately, there were no material fair value measurements with respect to nonfinancial assets or liabilities that are recognized or disclosed at fair value in the Company’s financial statements on a recurring basis for 2024 and 2023. 3M uses various valuation techniques, which are primarily based upon the market and income approaches, with respect to financial assets and liabilities. Following is a description of the valuation methodologies used for the respective financial assets and liabilities measured at fair value. •Available-for-sale marketable securities — except certain U.S. municipal securities: Marketable securities, except certain U.S. municipal securities, are valued utilizing multiple sources. A weighted average price is used for these securities. Market prices are obtained for these securities from a variety of industry standard data providers, security master files from large financial institutions, and other third-party sources. These multiple prices are used as inputs into a distribution-curve-based algorithm to determine the daily fair value to be used. 3M classifies U.S. treasury securities as level 1, while all other marketable securities (excluding certain U.S. municipal securities) are classified as level 2. Marketable securities are discussed further in Note 13. •Available-for-sale marketable securities —certain U.S. municipal securities only: 3M holds municipal securities with several cities in the United States as of December 31, 2024. Due to the nature of these securities, the valuation method references the carrying value of the corresponding finance lease obligation, and as such, will be classified as level 3 securities separately. •Solventum common stock: Solventum Corporation common stock is carried at stock prices that are readily available from active markets and are representative of fair value. 3M classifies this investment as Level 1. It is included within other assets on the Company’s consolidated balance sheet. •Derivative instruments: The Company’s derivative assets and liabilities within the scope of ASC 815, Derivatives and Hedging, are required to be recorded at fair value. The Company’s derivatives that are recorded at fair value include foreign currency forward and option contracts, interest rate swaps, and net investment hedges where the hedging instrument is recorded at fair value. Net investment hedges that use foreign currency denominated debt to hedge 3M’s net investment are not impacted by the fair value measurement standard under ASC 820, as the debt used as the hedging instrument is marked to a value with respect to changes in spot foreign currency exchange rates and not with respect to other factors that may impact fair value. 3M has determined that foreign currency forward and option contracts and interest rate swaps will be considered level 2 measurements. 3M uses inputs other than quoted prices that are observable for the asset. These inputs include foreign currency exchange rates, volatilities, and interest rates. Derivative positions are primarily valued using standard calculations/models that use as their basis readily observable market parameters. Industry standard data providers are 3M’s primary source for forward and spot rate information for both interest rates and currency rates, with resulting valuations periodically validated through third-party or counterparty quotes and a net present value stream of cash flows model. The following table provides information by level for material assets and liabilities that are measured at fair value on a recurring basis at December 31, 2024 and 2023.

The Company had no material activity with level 3 assets and liabilities during the periods presented. In addition, the plan assets of 3M’s pension and postretirement benefit plans are measured at fair value on a recurring basis (at least annually). Refer to Note 15. Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis: Disclosures are required for certain assets and liabilities that are measured at fair value, but are recognized and disclosed at fair value on a nonrecurring basis in periods subsequent to initial recognition. For 3M, such measurements of fair value relate primarily to indefinite-lived and long-lived asset impairments, goodwill impairments, and adjustment in carrying value of equity securities for which the measurement alternative of cost less impairment plus or minus observable price changes is used. There were no material impairments of assets or adjustments to equity securities using the measurement alternative for the periods presented. In 2022, management committed to a plan to exit and dispose of net assets in Russia through an intended sale of related subsidiaries. As a result, 3M recorded a pre-tax charge of $101 million, primarily within selling, general and administrative expense related to recording this held-for-sale disposal group at the lower of its fair value less cost to sell or carrying amount. In determining the carrying amount, the balance of cumulative translation adjustment within accumulated other comprehensive loss that would be eliminated upon sale was included and contributed to the impairment charge. As of December 31, 2022 the amounts of major assets and liabilities of this held-for-sale disposal group primarily included approximately $50 million within other current liabilities that largely represented a reserve against the balance of cumulative translation adjustment. In 2023, 3M closed on the sale of these subsidiaries, resulting in an immaterial gain after reversing this reserve while reclassifying the balance of cumulative translation adjustment into earnings. Additionally, in 2022, 3M committed to a plan to exit per- and polyfluoroalkyl substance (PFAS) manufacturing by the end of 2025. As a result, 3M recorded a pre-tax charge of $0.8 billion in 2022, related to impairment of long-lived and indefinite-lived assets ($0.5 billion — primarily associated with property, plant, and equipment) and impairment of goodwill ($0.3 billion). These charges were reflected within selling, general and administrative expense and goodwill impairment expense, respectively. The plan affects each of the Electronics Materials Solutions Division and Advanced Materials Division asset groupings/reporting units (both part of the Transportation and Electronics business) with impairment resulting for the Advanced Materials Division. Underlying fair values were determined primarily using discounted cash flow models based on assumptions of projected sales, EBITDA margins, capital expenditures, discount rates and other applicable items. Significant unobservable inputs used to estimate the fair values of the asset groupings included discount rates, which were 11% to 12%. Fair Value of Financial Instruments: The Company’s financial instruments include cash and cash equivalents, marketable securities, accounts receivable, certain investments, accounts payable, borrowings, and derivative contracts. The fair values of cash equivalents, accounts receivable, accounts payable, and short-term borrowings and current portion of long-term debt approximated carrying values because of the short-term nature of these instruments. The fair value of long-term notes receivable approximates the carrying value. Available-for-sale marketable securities and Solventum common stock are recorded at fair values as indicated in the preceding disclosures, in addition to certain investments and derivative instruments. To estimate fair values (classified as level 2) for its long-term debt, the Company utilized third-party quotes, which are derived all or in part from model prices, external sources, market prices, or the third-party’s internal records. Information with respect to the carrying amounts and estimated fair values of these financial instruments follow:
|  | December 31, 2024 |  | December 31, 2023
(Millions) |  | Carrying Value |  | Fair Value |  | Carrying Value |  | Fair Value
Long-term debt, excluding current portion |  | $ | 11,125 |  |  | $ | 9,856 |  |  | $ | 13,088 |  |  | $ | 11,859 |
The fair values reflected in the sections above consider the terms of the related debt absent the impacts of derivative/hedging activity. The carrying amount of long-term debt referenced above is impacted by certain fixed-to-floating interest rate swaps that are designated as fair value hedges and by the designation of certain fixed rate Eurobond securities issued by the Company as hedging instruments of the Company’s net investment in its European subsidiaries.
