MMM 3M Company

Item 2.02.  Results of Operations and Financial Condition

This Current Report on Form 8-K includes supplemental unaudited historical consolidated statement of income and business segment information related to (1) the impact of adopting Accounting Standards Update (ASU) No. 2017-07 relative to the presentation of pension and postretirement benefit costs and (2) business segment reporting changes reflecting the expansion of the Company’s dual credit reporting process internationally and centralization of certain manufacturing and supply technology platforms (provided on an annual and quarterly basis for the years ended December 31, 2017, 2016 and 2015). The Company did not operate under this segment structure for any of these prior periods and will begin to report comparative results under the new structure with the filing of its Quarterly Report on Form 10-Q for the quarter ending March 31, 2018.

Adoption of ASU No. 2017-07—Certain pension and postretirement costs reported outside operating income 

The Company adopted ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost , effective January 1, 2018 on a retrospective basis. This ASU changed how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the net periodic benefit cost in the income statement. Under the new standard, only the service cost component of net periodic benefit cost is included in operating expenses and only the service cost component is eligible for capitalization into assets such as inventory. All other net periodic benefit costs components (such as interest, expected return on plan assets, prior service cost amortization and actuarial gain/loss amortization) are reported outside of operating income.

Business Segment Reporting Changes

As part of 3M’s continuing effort to improve the alignment of its businesses around markets and customers, the Company made the following changes, effective in the first quarter of 2018, and other revisions impacting business segment reporting:

Consolidation of customer account activity within international countries – expanding dual credit reporting

Centralization of manufacturing and supply technology platforms
