Retirement Benefits [Abstract] |
Schedule of Reconciliation of the Beginning and Ending Balances of the Benefit Obligation and the Fair Value of Plan Assets | The following tables include a reconciliation of the beginning and ending balances of the benefit obligation and the fair value of plan assets as well as a summary of the related amounts recognized in the Company’s consolidated balance sheet as of December 31 of the respective years. 3M also has certain non-qualified unfunded pension and postretirement benefit plans, inclusive of plans related to supplement/excess benefits for employees impacted by particular relocations and other matters, that individually and in the aggregate are not significant and which are not included in the tables that follow. The obligations for these plans are included within other liabilities in the Company’s consolidated balance sheet and aggregated to less than $25 million as of December 31, 2024 and 2023. In connection with the completion of the April 1, 2024 separation of Solventum (see Note 2), approximately $2.7 billion of pension and postretirement benefit obligations and $2.4 billion of plan assets for certain pension and postretirement benefit plans, were transferred to Solventum, which is treated as a discontinued operation. These are reflected in the "Transfers to Solventum" row in the table below. In addition, as discussed later in this Note 15, in 2024 3M transferred a portion of its U.S. pension payment obligations and related plan assets to an insurance company. Those transfers are included as settlements and applicable portion in actuarial gain in the tables below.

* In accordance with ASC 820-10, certain investments that are measured at fair value using the net asset value (NAV) per share (or its equivalent) as a practical expedient have not been classified in the fair value hierarchy. The NAV is based on the fair value of the underlying assets owned by the fund, minus its liabilities then divided by the number of units outstanding and is determined by the investment manager or custodian of the fund. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the fair value of plan assets. The fair values of the assets held by the international pension plans by asset class are as follows:
