What is the main reason for this 8-K filing?

This 8-K filing is primarily to update 3M's 2010 Annual Report (10-K) to reflect reclassified historical results. These changes are due to product moves between business segments that became effective in the first quarter of 2011, aimed at better aligning businesses with markets and customers.

Which business segments were affected by these product moves?

The affected segments include Industrial and Transportation, Electro and Communications, Health Care, and Safety, Security and Protection Services. Product moves did not impact the Display and Graphics or Consumer and Office segments.

What was the financial impact of these segment realignments on 2010 net sales?

For the full year 2010, the product moves resulted in a net sales decrease of $152 million in the Industrial and Transportation segment and $8 million in the Health Care segment. These decreases were counterbalanced by net sales increases of $121 million in the Electro and Communications segment and $8 million in the Safety, Security and Protection Services segment, plus a $31 million adjustment related to eliminations.

Will these updated segment results be reflected in future financial reports?

Yes, the information presented in this 8-K updates specific parts of the 2010 Form 10-K. The company also notes that for significant developments since the 2010 10-K filing, investors should refer to subsequent 2011 Quarterly Reports on Form 10-Q.

MMM 8-K SEC Disclosure — May 26, 2011

Summary

3M Company (MMM) filed an 8-K on May 26, 2011, to update its previously filed 2010 Annual Report on Form 10-K. The primary purpose of this filing is to reflect reclassified historical financial results due to product moves between business segments, effective in the first quarter of 2011. These reclassifications are part of 3M's ongoing strategy to better align its businesses with market and customer needs, aiming to drive growth through structural adjustments. The report details specific product transfers, including pressure-sensitive adhesives and shock absorption/vibration dampening products moving from the Industrial and Transportation segment to the Electro and Communications segment, and medical respirator products moving from Health Care to Safety, Security and Protection Services. While these moves resulted in net sales decreases for the originating segments (Industrial and Transportation by $152 million, Health Care by $8 million), they were offset by net sales increases in the receiving segments (Electro and Communications by $121 million, Safety, Security and Protection Services by $8 million), along with a $31 million adjustment for dual credit sales and corporate allocations. These updated segment results will be incorporated into various sections of the 2010 10-K, including Business, Risk Factors, MD&A, and Financial Statements.
