Business Segments

As discussed in Note 17 to the Consolidated Financial Statements, effective in the first quarter of 2011, 3M made certain product moves between its business segments in its continuing effort to drive growth by aligning businesses around markets and customers.

Research and Patents

Research and product development constitutes an important part of 3M’s activities and has been a major driver of 3M’s sales growth. Research, development and related expenses totaled $1.570 billion in 2011, $1.434 billion in 2010 and $1.293 billion in 2009. Research and development, covering basic scientific research and the application of scientific advances in the development of new and improved products and their uses, totaled $1.036 billion in 2011, $919 million in 2010 and $838 million in 2009. Related expenses primarily include technical support provided by 3M to customers who are using existing 3M products; internally developed patent costs, which include costs and fees incurred to prepare, file, secure and maintain patents; and amortization of acquired patents.

The Company’s products are sold around the world under various trademarks. The Company also owns, or holds licenses to use, numerous U.S. and foreign patents. The Company’s research and development activities generate a steady stream of inventions that are covered by new patents. Patents applicable to specific products extend for varying periods according to the date of patent application filing or patent grant and the legal term of patents in the various countries where patent protection is obtained. The actual protection afforded by a patent, which can vary from country to country, depends upon the type of patent, the scope of its coverage and the availability of legal remedies in the country.

The Company believes that its patents provide an important competitive advantage in many of its businesses. In general, no single patent or group of related patents is in itself essential to the Company as a whole or to any of the Company’s business segments. The importance of patents in the Display and Graphics segment is described in “Performance by Business Segment” — “Display and Graphics Business” in Part II, Item 7, of this Form 10-K.

Raw Materials

In 2011, the Company experienced cost increases in most raw materials and transportation fuel costs. This was driven by higher basic feedstock costs, including petroleum based materials, metals, minerals and woodpulp-based products. To date, the Company is receiving sufficient quantities of all raw materials to meet its reasonably foreseeable production requirements. It is impossible to predict future shortages of raw materials or the impact any such shortages would have. 3M has avoided disruption to its manufacturing operations through careful management of existing raw material inventories and development and qualification of additional supply sources. 3M manages commodity price risks through negotiated supply contracts, price protection agreements and forward physical contracts.

Environmental Law Compliance

3M’s manufacturing operations are affected by national, state and local environmental laws around the world. 3M has made, and plans to continue making, necessary expenditures for compliance with applicable laws. 3M is also involved in remediation actions relating to environmental matters from past operations at certain sites. Refer to the “Environmental Matters and Litigation” section in Note 14, Commitments and Contingencies, for more detail.

Environmental expenditures relating to existing conditions caused by past operations that do not contribute to current or future revenues are expensed. Reserves for liabilities related to anticipated remediation costs are recorded on an undiscounted basis when they are probable and reasonably estimable, generally no later than the completion of feasibility studies or the Company’s commitment to a plan of action. Environmental expenditures for capital projects that contribute to current or future operations generally are capitalized and depreciated over their estimated useful lives.

In 2011, 3M invested about $15 million in capital projects to protect the environment. This amount excludes expenditures for remediation actions relating to existing matters caused by past operations that do not contribute to current or future revenues, which are expensed. Capital expenditures for environmental purposes have included pollution control devices — such as wastewater treatment plant improvements, scrubbers, containment structures, solvent recovery units and thermal oxidizers — at new and existing facilities constructed or upgraded in the normal course of business. Consistent with the Company’s policies stressing environmental responsibility, capital expenditures (other than for remediation projects) for known projects are presently expected to be about $31 million over the next two years for new or expanded programs to build facilities or modify manufacturing processes to minimize waste and reduce emissions.

While the Company cannot predict with certainty the future costs of such cleanup activities, capital expenditures or operating costs for environmental compliance, the Company does not believe they will have a material effect on its capital expenditures, earnings or competitive position.

Cautionary Note Concerning Factors That May Affect Future Results

This Annual Report on Form 10-K, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7, contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. The Company may also make forward-looking statements in other reports filed with the Securities and Exchange Commission, in materials delivered to shareholders and in press releases. In addition, the Company’s representatives may from time to time make oral forward-looking statements.

Forward-looking statements relate to future events and typically address the Company’s expected future business and financial performance. Words such as “plan,” “expect,” “aim,” “believe,” “project,” “target,” “anticipate,” “intend,” “estimate,” “will,” “should,” “could” and other words and terms of similar meaning, typically identify such forward-looking statements. In particular, these include, among others, statements relating to the Company’s

·    strategy for growth, future revenues, earnings, cash flow, uses of cash and other measures of financial performance, and market position,

·    worldwide economic and capital markets conditions, such as interest rates, foreign currency exchange rates, financial conditions of our suppliers and customers, and natural and other disasters affecting the operations of the Company or our suppliers and customers,

·    new business opportunities, product development, and future performance or results of current or anticipated products,

·    the scope, nature or impact of acquisition, strategic alliance and divestiture activities,

·    the outcome of contingencies, such as legal and regulatory proceedings,

·    future levels of indebtedness, common stock repurchases and capital spending,

·    future availability of and access to credit markets,

·    pension and postretirement obligation assumptions and future contributions, asset impairments, tax liabilities, information technology security, and

·    the effects of changes in tax, environmental and other laws and regulations in the United States and other countries in which we operate.

The Company assumes no obligation to update or revise any forward-looking statements.

Forward-looking statements are based on certain assumptions and expectations of future events and trends that are subject to risks and uncertainties. Actual future results and trends may differ materially from historical results or those reflected in any such forward-looking statements depending on a variety of factors. Important information as to these factors can be found in this document, including, among others, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under the headings of “Overview,” “Critical Accounting Estimates” and “Financial Condition and Liquidity.”  Discussion of these factors is incorporated by reference from Part I, Item 1A, “Risk Factors,” of this document, and should be considered an integral part of Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”  For additional information concerning factors that may cause actual results to vary materially from those stated in the forward-looking statements, see our reports on Form 10-K, 10-Q and 8-K filed with the SEC from time to time.

Item 1A. Risk Factors

Provided below is a cautionary discussion of what we believe to be the most important risk factors applicable to the Company. Discussion of these factors is incorporated by reference into and considered an integral part of Part II, Item 7, “Management’s Discussion and Analysis of Financial Conditions and Results of Operations.”

* Results are impacted by the effects of, and changes in, worldwide economic and capital markets conditions. The Company operates in more than 65 countries and derives approximately two-thirds of its revenues from outside the United States. The Company’s business is subject to global competition and may be adversely affected by factors in the United States and other countries that are beyond its control, such as disruptions in financial markets, economic downturns in the form of either contained or widespread recessionary conditions, elevated unemployment levels, sluggish or uneven recovery, in specific countries or regions, or in the various industries in which the Company operates; social, political or labor conditions in specific countries or regions; natural and other disasters affecting the operations of the Company or its customers and suppliers; or adverse changes in the availability and cost of capital, interest rates, tax rates, or regulations in the jurisdictions in which the Company operates.

* The Company’s credit ratings are important to 3M’s cost of capital. The major rating agencies routinely evaluate the Company’s credit profile and assign debt ratings to 3M. The Company currently has an AA- credit rating, with a stable outlook, from Standard & Poor’s and an Aa2 credit rating, with a stable outlook, from Moody’s Investors Service. This evaluation is based on a number of factors, which include financial strength, business and financial risk,

9

Table of Contents

as well as transparency with rating agencies and timeliness of financial reporting. The Company’s current ratings have served to lower 3M’s borrowing costs and facilitate access to a variety of lenders. Failure to maintain the current ratings level would adversely affect the Company’s cost of funds and could adversely affect liquidity and access to capital markets.

* The Company’s results are affected by competitive conditions and customer preferences. Demand for the Company’s products, which impacts revenue and profit margins, is affected by (i) the development and timing of the introduction of competitive products; (ii) the Company’s response to downward pricing to stay competitive; (iii) changes in customer order patterns, such as changes in the levels of inventory maintained by customers and the timing of customer purchases which may be affected by announced price changes, changes in the Company’s incentive programs, or the customer’s ability to achieve incentive goals; and (iv) changes in customers’ preferences for our products, including the success of products offered by our competitors, and changes in customer designs for their products that can affect the demand for some of the Company’s products.

* Foreign currency exchange rates and fluctuations in those rates may affect the Company’s ability to realize projected growth rates in its sales and earnings. Because the Company’s financial statements are denominated in U.S. dollars and approximately two-thirds of the Company’s revenues are derived from outside the United States, the Company’s results of operations and its ability to realize projected growth rates in sales and earnings could be adversely affected if the U.S. dollar strengthens significantly against foreign currencies.

* The Company’s growth objectives are largely dependent on the timing and market acceptance of its new product offerings, including its ability to continually renew its pipeline of new products and to bring those products to market. This ability may be adversely affected by difficulties or delays in product development, such as the inability to identify viable new products, obtain adequate intellectual property protection, or gain market acceptance of new products. There are no guarantees that new products will prove to be commercially successful.

* The Company’s future results are subject to fluctuations in the costs and availability of purchased components, compounds, raw materials and energy, including oil and natural gas and their derivatives, due to shortages, increased demand, supply interruptions, currency exchange risks, natural disasters and other factors. The Company depends on various components, compounds, raw materials, and energy (including oil and natural gas and their derivatives) supplied by others for the manufacturing of its products. It is possible that any of its supplier relationships could be interrupted due to natural and other disasters and other events, or be terminated in the future. Any sustained interruption in the Company’s receipt of adequate supplies could have a material adverse effect on the Company. In addition, while the Company has a process to minimize volatility in component and material pricing, no assurance can be given that the Company will be able to successfully manage price fluctuations or that future price fluctuations or shortages will not have a material adverse effect on the Company.

* Acquisitions, strategic alliances, divestitures, and other unusual events resulting from portfolio management actions and other evolving business strategies, and possible organizational restructuring could affect future results. The Company monitors its business portfolio and organizational structure and has made and may continue to make acquisitions, strategic alliances, divestitures and changes to its organizational structure. With respect to acquisitions, future results will be affected by the Company’s ability to integrate acquired businesses quickly and obtain the anticipated synergies.

* The Company’s future results may be affected if the Company generates fewer productivity improvements than estimated. The Company utilizes various tools, such as Lean Six Sigma, to improve operational efficiency and productivity. There can be no assurance that all of the projected productivity improvements will be realized.

* Security breaches and other disruptions to the Company’s information technology infrastructure could interfere with the Company’s operations, compromise information belonging to the Company and its customers and suppliers, and expose the Company to liability which could adversely impact the Company’s business and reputation. In the ordinary course of business, the Company relies on information technology networks and systems, some of which are managed by third parties, to process, transmit and store electronic information, and to manage or support a variety of business processes and activities. Additionally, the Company collects and stores sensitive data, including proprietary business information. Despite security measures and business continuity plans, the Company’s information technology networks and infrastructure may be vulnerable to damage, disruptions or shutdowns due to attack by hackers or breaches, employee error or malfeasance, power outages, computer viruses, telecommunication or utility failures, systems failures, natural disasters or other catastrophic events. Any such events could result in legal claims or proceedings, liability or penalties under privacy laws, disruption in operations, and damage to the Company’s reputation, which could adversely affect the Company’s business.

* The Company’s future results may be affected by various legal and regulatory proceedings and legal compliance risks, including those involving product liability, antitrust, environmental, the U.S. Foreign Corrupt Practices Act and other anti-bribery, anti-corruption, or other matters. The outcome of these legal proceedings may differ from the Company’s expectations because the outcomes of litigation, including regulatory matters, are often difficult to reliably predict. Various factors or developments can lead the Company to change current estimates of liabilities and related insurance receivables where applicable, or make such estimates for matters previously not susceptible of reasonable estimates, such as a significant judicial ruling or judgment, a significant settlement, significant regulatory developments or changes in applicable law. A future adverse ruling, settlement or unfavorable development could result in future charges that could have a material adverse effect on the Company’s results of operations or cash flows in any particular period. For a more detailed discussion of the legal proceedings involving the Company and the associated accounting estimates, see the discussion in Note 14 “Commitments and Contingencies” within the Notes to Consolidated Financial Statements.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

3M’s general offices, corporate research laboratories, and certain division laboratories are located in St. Paul, Minnesota. The Company operates 81 manufacturing facilities in 28 states. The Company operates 133 manufacturing and converting facilities in 40 countries outside the United States.

3M owns the majority of its physical properties. 3M’s physical facilities are highly suitable for the purposes for which they were designed. Because 3M is a global enterprise characterized by substantial intersegment cooperation, properties are often used by multiple business segments.

Item 3. Legal Proceedings.

Discussion of legal matters is incorporated by reference from Part II, Item 8, Note 14, “Commitments and Contingencies,” of this document, and should be considered an integral part of Part I, Item 3, “Legal Proceedings.”

Repurchases of 3M common stock are made to support the Company’s stock-based employee compensation plans and for other corporate purposes. In February 2007, 3M’s Board of Directors authorized a two-year share repurchase of up to $7.0 billion for the period from February 12, 2007 to February 28, 2009. In February 2009, 3M’s Board of Directors extended this share repurchase authorization with no pre-established end date. In February 2011, 3M’s Board of Directors replaced the Company’s existing repurchase program with a new repurchase program. This new program authorizes the repurchase of up to $7.0 billion of 3M’s outstanding common stock, with no pre-established end date.

Item 6. Selected Financial Data.

Items included in the preceding table which had a significant impact on results are summarized as follows. 2010 included a one-time, non-cash income tax charge of $84 million, or 12 cents per diluted share, resulting from the March 2010 enactment of the Patient Protection and Affordable Care Act, including modifications made in the Health Care and Education Reconciliation Act of 2010. 2009 results included net losses that decreased operating income by $194 million and net income attributable to 3M by $119 million. 2009 included restructuring actions ($209 million pre-tax, $128 million after tax and noncontrolling interest), which were partially offset by a gain on sale of real estate ($15 million pre-tax, $9 million after tax). 2008 results included net losses that decreased operating income by $269 million and net income attributable to 3M by $194 million. 2008 included restructuring actions ($229 million pre-tax, $147 million after-tax and noncontrolling interest), exit activities ($58 million pre-tax, $43 million after-tax) and losses related to the sale of businesses ($23 million pre-tax, $32 million after-tax), which were partially offset by a gain on sale of real estate ($41 million pre-tax, $28 million after-tax). 2007 results included net gains that increased operating income by $681 million and net income attributable to 3M by $448 million. 2007 included gains related to the sale of businesses ($849 million pre-tax, $550 million after-tax) and a gain on sale of real estate ($52 million pre-tax, $37 million after-tax), which were partially offset by increases in environmental liabilities ($134 million pre-tax, $83 million after-tax), restructuring actions ($41 million pre-tax, $27 million after-tax), and exit activities ($45 million pre-tax, $29 million after-tax).

·       Overview

·       Results of Operations

·       Performance by Business Segment

·       Performance by Geographic Area

·       Critical Accounting Estimates

·       New Accounting Pronouncements

·       Financial Condition and Liquidity

·       Financial Instruments

OVERVIEW

3M is a diversified global manufacturer, technology innovator and marketer of a wide variety of products. As discussed in Note 17 to the Consolidated Financial Statements, effective in the first quarter of 2011, 3M made certain product moves between its business segments in its continuing effort to drive growth by aligning businesses around markets and customers. The financial information presented herein reflects the impact of these changes for all periods presented. 3M manages its operations in six operating business segments: Industrial and Transportation; Health Care; Consumer and Office; Safety, Security and Protection Services; Display and Graphics; and Electro and Communications.

Fourth-quarter 2011 sales totaled $7.1 billion, an increase of 5.7 percent from the fourth quarter of 2010. Net income attributable to 3M was $954 million, or $1.35 per diluted share in the fourth quarter of 2011, compared to $928 million, or $1.28 per diluted share, in the fourth quarter of 2010. 3M’s sales growth was led by its industrial-oriented businesses, along with steady growth in consumer and health care. The business environment remained challenging, impacted by deteriorating demand in Western Europe and slower consumer electronics activity. While sales grew across much of the portfolio, sales of optical films for LCD TVs remained weak and momentum also slowed in other parts of electronics. Four of the Company’s six business segments showed growth in sales, led by Industrial and Transportation at 14.3 percent, Safety, Security and Protection Services at 9.4 percent, Consumer and Office at 6.1 percent, and Health Care at 5.4 percent. A slowdown in electronics-related businesses negatively impacted both the Electro and Communications and Display and Graphics business segments. Electro and Communications sales decreased 2.7 percent and Display and Graphics sales declined 8.8 percent. Sales declined 17 percent in optical systems, which is part of Display and Graphics, impacted by end-market weakness and lower attachment rates in LCD TVs.

Fourth-quarter 2011 sales increased in every major geographic region, with Latin America/Canada up 9.7 percent, the U.S. up 7.4 percent, Europe/Middle East/Africa up 4.4 percent, and Asia Pacific up 2.8 percent. Excluding optical systems, Asia Pacific sales increased 7.6 percent. Of the 5.7 percent worldwide sales growth, 3.3 points was from the combined impact of higher organic volume of 1.3 points and selling price growth of 2.0 points, 2.3 points was from acquisitions, and 0.1 points was from favorable currency effects. Organic volume growth of 1.3 percent reflected slower growth in Asia Pacific, partially due to weakness across the electronics market and slower growth in China, in addition to weakness in Western Europe.

During 2011, 3M was impacted by the first-quarter earthquake and tsunami in Japan and by the fourth-quarter flooding in Thailand. Automobile and electronic manufacturers were most impacted; thus, 3M’s automotive OEM and electronics-related businesses were most affected. 3M estimates that combined direct and indirect business disruption resulting from the 2011 Japan natural disaster, net of the benefit from sales of 3M products used in the reconstruction efforts and initial insurance recoveries, plus the impact of Thailand flooding, reduced 2011 sales growth by an estimated 0.8 percentage points and earnings by approximately 6 cents per diluted share, with most of this impact in the first half of 2011. In the fourth quarter of 2011, the flooding in Thailand reduced sales growth by an estimated $35 million and operating income by $20 million, with this operating income effect offset by $23 million in insurance recoveries related to the earthquake and tsunami in Japan. Japan represented approximately 9 percent of total 3M sales for total year 2011. As conditions improve, 3M has been working to capture additional sales for its businesses, such as products used in clean-up (construction and home improvement products), safety-related products (respirator masks and personal protective equipment), energy savings/refurbishment products (window films) and products that help in the rebuilding effort (traffic safety, telecommunication/utility and commercial construction). Related to these natural disasters, based on 3M’s current assessment, no material asset or investment impairments have been recorded. In addition, 3M is not aware of any significant issues related to these natural

14

Table of Contents

disasters concerning inventory, customer receivables, lease terminations, environmental exposures, guarantees, indemnifications, debt covenant compliance, or significant tax issues. 3M does have certain insurance coverage which limits its exposure and resulted in some initial recovery in the fourth quarter of 2011 (as discussed above).

Sales in 2011 increased 11.1 percent to $29.6 billion, led by Industrial and Transportation, Safety, Security and Protection Services, and Health Care. All major geographic regions showed improvement, led by Latin America/Canada. The increase in global sales reflected improved market penetration and new product flow along with significant growth in important end-markets such as general industrial and personal safety. Net income attributable to 3M was $4.283 billion, or $5.96 per diluted share in 2011, compared to $4.085 billion, or $5.63 per diluted share, in 2010 (including the first-quarter 2010 special item discussed below).

Fourth-quarter 2010 sales grew nearly 10 percent to $6.7 billion, despite negative comparisons from H1N1 and moderating sales growth in optical films for LCD TVs. Sales growth was broad-based, with organic sales volumes expanding in all businesses, led by an 18.7 percent increase in Electro and Communications and a 14.7 percent increase in Display and Graphics. Geographically, organic sales volume was strongest in Asia Pacific at 18.1 percent and Latin America at 12.2 percent. Net income attributable to 3M in the fourth quarter of 2010 was $928 million, or $1.28 per diluted shares, compared to $935 million, or $1.30 per diluted share, in the fourth quarter of 2009. Fourth-quarter income was penalized by year-on-year H1N1-related comparisons, increases in raw material costs, and investments to accelerate future growth. 3M invested in research and development, sales and marketing (including advertising and merchandising investments), and also incurred acquisition-related costs in the fourth quarter. 3M made several large fourth-quarter 2010 acquisitions, including Arizant Inc., Attenti Holdings S.A. and Cogent Inc.

For total year 2010, the Company posted 2010 sales of $26.7 billion, up 15.3 percent. During the year, 3M invested significantly to improve long-term growth. For example, research, development and related expenses of $1.4 billion helped to drive innovation and new product sales. 3M also accelerated sales and marketing investments in high-growth markets to help secure future growth. All businesses posted positive organic volume growth, led by Display and Graphics at 26.5 percent, Electro and Communications at 26.0 percent, and Industrial and Transportation at 16.6 percent. Including special items (discussed below), net income attributable to 3M in 2010 was $4.085 billion, or $5.63 per diluted share, compared to $3.193 billion or $4.52 per diluted share, in 2009.

In 2010, 3M recorded a one-time, non-cash income tax charge of $84 million, or 12 cents per diluted share, resulting from the March 2010 enactment of the Patient Protection and Affordable Care Act, including modifications made in the Health Care and Education Reconciliation Act of 2010. Refer to the special items discussion at the end of this overview section for more detail.

3M has been aggressively restructuring the company since early 2008 and continued this effort through the third quarter of 2009, with these restructuring actions and exit activities resulting in an aggregate reduction of approximately 6,400 positions. The related net restructuring charges and other special items reduced net income attributable to 3M for year 2009 by $119 million, or $0.17 per diluted share. Refer to the special items discussion at the end of this overview section for more detail. These restructuring actions and exit activities resulted in savings of almost $400 million in 2009 and additional incremental savings of more than $150 million in 2010, with the majority of 2010’s benefit in the first half of the year. In addition, 3M amended its policy regarding banked vacation in 2009, which added more than $100 million to operating income in 2009, with a benefit of approximately $80 million in 2010.

The following table contains sales and operating income results by business segment for the years ended December 31, 2011 and 2010. In addition to the discussion below, refer to the section entitled “Performance by Business Segment” and “Performance by Geographic Area” later in MD&A for a more detailed discussion of the sales and income results of the Company and its respective business segments (including Corporate and Unallocated). Refer to Note 17 for additional information on business segments, including Elimination of Dual Credit.

Sales in 2011 increased 11.1 percent, led by Industrial and Transportation at 19.5 percent, Safety, Security and Protection Services at 15.2 percent, and Health Care at 11.5 percent. Electro and Communications sales increased 8.6 percent and Consumer and Office sales increased 7.8 percent. Sales declined 5.4 percent in Display and Graphics, due to fewer orders for optical films. Total company local-currency sales growth (which includes volume, selling price and acquisition impacts, but excludes divestiture and translation impacts) was 8.0 percent and foreign currency impacts added 3.1 percent. 3M’s business segments all posted operating income margins in excess of 20 percent in 2011 and 2010. Worldwide operating income margins for 2011 were 20.9 percent, compared to 22.2 percent for 2010.

In 2010, sales increased 15.3 percent, led by Electro and Communications at 27.5 percent, Display and Graphics at 24.0 percent, Industrial and Transportation at 18.4 percent, and Consumer and Office at 11.0 percent. Sales growth in these business segments was led by consumer electronics, automotive OEM, renewable energy, and broad-based consumer and office growth, as well as sales growth in those businesses that serve the broad industrial manufacturing sector. Local-currency sales (which includes volume, selling price and acquisition impacts, but excludes divestiture and translation impacts) increased 14.4 percent. Foreign currency effects added 1.0 percent to sales, while divestiture impacts reduced sales by 0.1 percent. Operating income margins for 2010 were 22.2 percent, compared to 20.8 percent in 2009.

3M generated approximately $5.3 billion of operating cash flows in 2011, an increase of $110 million when compared to 2010. This followed an increase of $233 million when comparing 2010 to 2009. Refer to the section entitled “Financial Condition and Liquidity” later in MD&A for a discussion of items impacting cash flows. In February 2011, 3M’s Board of Directors authorized the repurchase of up to $7.0 billion of 3M’s outstanding common stock, which replaced the Company’s previous repurchase program. The current authorization has no pre-established end date. In 2011, the Company purchased $2.701 billion of treasury stock, of which a portion was under the previous authorization, compared to $854 million of treasury stock repurchases in 2010. In 2009, the Company placed added emphasis on maintaining ample liquidity and enhancing balance sheet strength. As a result, share repurchase activity was minimal and no broker repurchases of stock were made. As of December 31, 2011, approximately $4.6 billion of 3M common stock remained available for repurchase under the current authorization. In February 2012, 3M’s Board of Directors authorized a dividend increase of 7.3 percent for 2012, marking the 54th consecutive year of dividend increases for 3M. 3M’s debt to total capital ratio (total capital defined as debt plus equity) was 25 percent at both December 31, 2011 and December 31, 2010, compared to 30 percent at December 31, 2009. 3M has an AA- credit rating with a stable outlook from Standard & Poor’s and an Aa2 credit rating with a stable outlook from Moody’s Investors Service. The Company has significant cash on hand and sufficient additional access to capital markets to meet its funding needs.

In 2011, the Company experienced cost increases in most raw materials and transportation fuel costs. This was driven by higher basic feedstock costs, including petroleum based materials, metals, minerals and woodpulp-based products. To date the Company is receiving sufficient quantities of all raw materials to meet its reasonably foreseeable production requirements. It is impossible to predict future shortages of raw materials or the impact any such shortages would have. 3M has avoided disruption to its manufacturing operations through careful management of existing raw material inventories and development and qualification of additional supply sources. 3M manages commodity price risks through negotiated supply contracts, price protection agreements and forward physical contracts.

On a worldwide basis, 3M’s pension and postretirement plans were 82 percent funded at year-end 2011. The U.S. qualified plans, which are approximately 71 percent of the worldwide pension obligation, were 86 percent funded, the international pension plans were 87 percent funded, and the U.S. non-qualified pension plan is not funded. Asset returns in 2011 for the U.S. qualified plan were 8.7%. The year-end 2011 discount rate was 4.15%, down 1.08 percentage points from the 2010 discount rate of 5.23%. The decrease in discount rates, both U.S. and internationally, resulted in a significantly higher valuation of the projected benefit obligation, which reduced the plans’ funded status. The changes in 3M’s defined-benefit pension and postretirement plans’ funded status significantly impacted several balance sheet lines. These changes increased long-term liabilities by approximately $2.4 billion and decreased stockholders’ equity by approximately $1.6 billion, with the other major impact primarily related to increased deferred taxes within other assets. Other pension and postretirement changes during the year, such as contributions and amortization, also impacted these balance sheet captions.

3M expects to contribute approximately $800 million to $1 billion of cash to its global pension and postretirement plans in 2012, with approximately $300 million in each of the first and second quarters. The Company does not have a required minimum cash pension contribution obligation for its U.S. plans in 2012. 3M expects pension and postretirement benefit expense in 2012 to increase by approximately $89 million pre-tax, or approximately 9 cents per diluted share, when compared to 2011. This 9 cents per diluted share increase includes the costs associated with a voluntary incentive program (discussed in next paragraph). Refer to “Critical Accounting Estimates” within MD&A and Note 11 (Pension and Postretirement Benefit Plans) for additional information concerning 3M’s pension and post-retirement plans.

3M expects to incur early retirement/restructuring costs of approximately 4 cents per diluted share in the first quarter of 2012. Of this amount, approximately 3 cents per diluted share relates to special termination benefits for the voluntary retirement incentive program in the United States (discussed in Note 11). The remainder relates to selective restructuring in a few developed countries. These actions, in aggregate, are expected to be neutral to full-year 2012 earnings, with the costs incurred in the first quarter of 2012, and the associated benefits realized over the remainder of 2012.

There are a few major items that will negatively impact earnings in 2012. As discussed further above, 3M expects that pension and postretirement expense will decrease 2012 earnings, when compared to 2011, by approximately 9 cents per diluted share. 3M’s early assessment of the income tax rate indicates an expected 2012 effective tax rate of approximately 29.5 percent compared to 27.8 percent for 2011. In addition, currency effects are expected to have a negative impact on earnings. 3M currently expects that sales growth and related incremental income, in addition to expected productivity improvements, selling price increases in excess of raw material inflation, and other benefits, should more than offset the items that will negatively impact earnings.

Forward-looking statements in Item 7 may involve risks and uncertainties that could cause results to differ materially from those projected (refer to the section entitled “Cautionary Note Concerning Factors That May Affect Future Results” in Item 1 and the risk factors provided in Item 1A for discussion of these risks and uncertainties).

Special Items:

Special items represent significant charges or credits that are important to understanding changes in the Company’s underlying operations.

In 2010, 3M recorded a one-time, non-cash income tax charge of $84 million, or 12 cents per diluted share, resulting from the March 2010 enactment of the Patient Protection and Affordable Care Act, including modifications made in the Health Care and Education Reconciliation Act of 2010 (collectively, the “Act”). The charge is due to a reduction in the value of the company’s deferred tax asset as a result of the Act’s change to the tax treatment of Medicare Part D reimbursements. This item is discussed in more detail in Note 8 (Income Taxes).

In 2009, net losses for restructuring and other actions decreased operating income by $194 million and net income attributable to 3M by $119 million, or $0.17 per diluted share. 2009 included restructuring actions ($209 million pre-tax, $128 million after tax and noncontrolling interest), which were partially offset by a gain on sale of real estate ($15 million pre-tax, $9 million after tax). The gain on sale of real estate relates to the June 2009 sale of a New Jersey roofing granule facility, which is recorded in cost of sales within the Safety, Security and Protection Services business segment. Restructuring is discussed in more detail in Note 4 (Restructuring Actions).

RESULTS OF OPERATIONS

Net Sales:

In 2011, local-currency sales increased 8.0 percent. All major geographic areas showed local-currency sales increases, led by Latin America/Canada and the United States. Worldwide local-currency sales growth was led by Industrial and Transportation at 15.9 percent, Safety, Security and Protection Services at 11.8 percent, and Health Care at 8.4 percent. Acquisitions added 3.3 percent to worldwide growth and currency impacts benefited 2011 worldwide sales growth by 3.1 percent. Worldwide selling prices rose 1.0 percent in 2011, despite selling price declines in 3M’s optical systems business, where prices typically decline each year, which is common for the electronics’ industry. Selling prices in 3M’s non optical systems businesses increased by approximately 1.6 percent.

In 2010, local-currency sales increased 14.4 percent. All major geographic areas showed local-currency sales increases, led by Asia Pacific. Worldwide local-currency sales growth was led by Electro and Communications at 26.1 percent, Display and Graphics at 23 percent, Industrial and Transportation at 17.2 percent and Consumer and Office at 10 percent. Refer to the sections entitled “Performance by Business Segment” and “Performance by Geographic Area” later in MD&A for additional discussion of sales change.

Operating Expenses:

As discussed in the preceding overview section, 2009 included restructuring charges, partially offset by a gain on sale of real estate, which combined decreased operating income by $194 million, or 0.9 percent of net sales. There were no special items that impacted operating income in 2011 or 2010. The following tables summarize the 2009 special items by income statement caption.

18

Table of Contents

Pension and postretirement expense increased in both 2011 and 2010. The year-on-year increase for 2011 compared to 2010, and 2010 compared to 2009, was $233 million and $99 million, respectively. These increases negatively impacted cost of sales; selling, general and administrative expenses (SG&A); and research, development and related expenses (R&D).

Cost of Sales:

Cost of sales includes manufacturing, engineering and freight costs. Cost of sales, measured as a percent of net sales, was 53.0 percent in 2011, an increase of 1.1 percentage points from 2010 levels. On a dollar basis, selling price increases largely offset raw material inflation for total year 2011, as selling prices increased 1 percent year-on-year and gross raw material prices increased approximately 4 percent year-on-year. However, measured as a percent of sales, selling price/gross raw material impacts accounted for approximately 0.5 percentage points of the cost of sales increase. As discussed in the preceding paragraph, cost of sales as a percent of net sales was also negatively impacted by higher pension and postretirement costs. These impacts were partially offset by organic sales volume growth of 3.7 percent.

Cost of sales, measured as a percent of net sales, was 51.9 percent in 2010, a decrease of 0.5 percentage points from 2009. A number of positive factors impacted year-on-year results. These factors included 13.7 percent growth in organic sales volume, improved factory utilization levels, along with cost savings related to prior years’ restructuring actions. In addition, 2009 included a penalty of 0.5 percentage points (as a percent of net sales) related to special items. As discussed in Note 4 (Restructuring Actions), in 2009, 3M recorded $209 million in restructuring charges, of which $110 million was recorded in cost of sales. This was partially offset by a $15 million gain on sale of a New Jersey roofing granule facility, which was also recorded in cost of sales. In addition, 3M decided to swap Venezuelan bolivars into U.S. dollars in 2009, given the economic conditions in Venezuela at that time, which also negatively impacted cost of sales in 2009. These year-on-year net benefits were partially offset by pricing impacts, as selling prices declined 0.2 percent year-on-year, and gross raw material prices increased approximately 2 percent year-on-year.

Selling, General and Administrative Expenses:

Selling, general and administrative (SG&A) expenses increased 13 percent in 2011 when compared to 2010, due to several factors. Approximately 5 percentage points of this growth in SG&A was due to increases from businesses acquired in the last twelve months, primarily related to SG&A spending for the Winterthur Technologie AG, Arizant Inc., Cogent Inc. and Attenti Holdings S.A. acquisitions. Another 3 percentage points of growth in 2011 SG&A was due to foreign exchange effects, which resulted in higher translated costs from 3M’s non-U.S. subsidiaries. Finally, 2011 SG&A increased in part due to higher year-on-year pension and postretirement expense and continued investments to support future growth, such as sales representatives, advertising and promotional investments. SG&A expenses, measured as a percent of net sales, increased 0.3 percentage points in 2011 compared to 2010.

Selling, general and administrative (SG&A) expenses increased 12 percent in 2010 when compared to 2009. In 2010, sales and marketing expenses increased 14 percent, which included advertising and promotion investment increases of over 20 percent in 2010, which helped drive sales volumes. In addition, 3M increased both sales coverage and its marketing strength, particularly in faster-growing emerging economies. In 2010, general and administrative costs remained under control, as these costs increased at approximately half the rate of 2010 sales growth. SG&A expenses, measured as a percent of net sales, decreased 0.7 percentage points in 2010 compared to 2009. As indicated in Note 4, restructuring expenses of $91 million were recorded in SG&A expenses in 2009. Measured as a percent of sales, these restructuring expenses increased 2009 SG&A expenses by 0.4 percentage points.

Research, Development and Related Expenses:

Research, development and related expenses (R&D) expense increased 9.5 percent in 2011 compared to 2010, and increased 11 percent in 2010 compared to 2009, as 3M continued to support its key growth initiatives. In 2011, R&D expense increased versus 2010 due to R&D related to businesses acquired in the last 12 months, foreign exchange effects, and higher pension and postretirement expense, in addition to 3M’s continued investment in new products. R&D, measured as a percent of sales, was 5.3 percent in 2011, compared to 5.4 percent in 2010 and 5.6 percent in 2009.

Operating Income:

3M uses operating income as one of its primary business segment performance measurement tools. Operating income was 20.9 percent of sales in 2011, compared to 22.2 percent of sales in 2010, primarily due to higher cost of

19

Table of Contents

sales (as a percent of sales) in 2011 when compared to 2010. Operating income was 20.8 percent of sales in 2009. 2009 was negatively impacted by restructuring expenses, net of a gain on sale of real estate, which on a combined basis decreased operating income by 0.9 percentage points ($194 million).

Interest Expense and Income:

Interest Expense: Interest expense decreased in both 2011 and 2010, driven by lower average U.S. debt balances and lower interest rates.

Interest Income: In 2011, interest income increased slightly, as higher international cash balances and better investment yields were largely offset by a lower U.S. cash balance. In 2010, interest income also increased slightly, with higher average cash and cash equivalent balances largely offset by lower interest rates.

Provision for Income Taxes:

The effective tax rate for 2011 was 27.8 percent, compared to 27.7 percent in 2010, an increase of 0.1 percent. The year-on-year change in international income taxes increased the effective tax rate for 2011 when compared to 2010 by approximately 2.5 percent, which includes a partial offsetting benefit from the corporate reorganization of a wholly owned international subsidiary in 2011. This 2.5 percent net increase was due primarily to certain 2010 tax benefits, which did not repeat in 2011, related to net operating losses partially offset by a valuation allowance resulting from the 2010 corporate alignment transactions that allowed the Company to increase its ownership of a foreign subsidiary. These transactions are described in the section of Note 6 entitled “Purchase and Sale of Subsidiary Shares and Transfers of Ownership Interests Involving Non-Wholly Owned Subsidiaries”. Other significant items impacting the year-on-year comparison include a one-time 2010 income tax charge of $84 million, which benefited the 2011 tax rate when compared to 2010 by 1.5 percent, as this charge did not repeat in 2011. This 2010 charge was a result of the March 2010 enactment of the Patient Protection and Affordable Care Act, including modifications made in the Health Care and Education Reconciliation Act of 2010. The Company’s effective tax rate also benefited during 2011 when compared to 2010 by approximately 0.7 percent from adjustments to its income tax reserves.

The effective tax rate for 2010 was 27.7 percent, compared to 30.0 percent in 2009, a decrease of 2.3 percent. This included an approximately 1.8 percent decrease related to the year-on-year change in international income taxes, due primarily to the corporate alignment transactions discussed above. Additionally, the Company’s effective tax rate benefited in 2010 compared to 2009 by approximately 1.3 percent from adjustments to its income tax reserves, and by approximately 0.9 percent from additional Domestic Manufacturer’s deductions. These benefits were partially offset by a 1.5 percent increase related to the one-time 2010 income tax charge of $84 million.

On December 17, 2010, the provision for the research and development credit was extended by the “2010 Tax Relief Act” for expenditures incurred up to December 31, 2011. The expiration of this research and development credit will have a negative impact on the effective tax rate in 2012 and forward if this credit is not extended in future years.

The company currently expects that its effective tax rate for total year 2012 will be approximately 29.5 percent. The rate can vary from quarter to quarter due to discrete items, such as the settlement of income tax audits and changes in tax laws, as well as recurring factors, such as the geographic mix of income before taxes.

Refer to Note 8 for further discussion of income taxes.

Net Income Attributable to Noncontrolling Interest:

Net income attributable to noncontrolling interest represents the elimination of the income or loss attributable to non-3M ownership interests in 3M consolidated entities. The changes in noncontrolling interest amounts are primarily

related to Sumitomo 3M Limited (Japan), which is 3M’s most significant consolidated entity with non-3M ownership interests. As of December 31, 2011, 3M’s effective ownership in Sumitomo 3M Limited is 75 percent.

Currency Effects:

3M estimates that year-on-year currency effects, including hedging impacts, increased net income attributable to 3M by approximately $154 million in 2011 and increased net income attributable to 3M by approximately $15 million in 2010. This estimate includes the effect of translating profits from local currencies into U.S. dollars; the impact of currency fluctuations on the transfer of goods between 3M operations in the United States and abroad; and transaction gains and losses, including derivative instruments designed to reduce foreign currency exchange rate risks and the negative impact of swapping Venezuelan bolivars into U.S. dollars. 3M estimates that year-on-year derivative and other transaction gains and losses had an immaterial impact on net income attributable to 3M in 2011 and decreased net income attributable to 3M by approximately $115 million in 2010.

PERFORMANCE BY BUSINESS SEGMENT

Disclosures relating to 3M’s business segments are provided in Item 1, Business Segments. Financial information and other disclosures are provided in the Notes to the Consolidated Financial Statements. As discussed in Note 17 to the Consolidated Financial Statements, effective in the first quarter of 2011, 3M made certain product moves between its business segments in its continuing effort to drive growth by aligning businesses around markets and customers. Segment information presented herein reflects the impact of these changes for all periods presented. The reportable segments are Industrial and Transportation; Health Care; Consumer and Office; Safety, Security and Protection Services; Display and Graphics; and Electro and Communications. Information related to 3M’s business segments is presented in the tables that follow. Local-currency sales change amounts are separated into organic local-currency sales (which include both organic volume impacts plus selling price impacts) and acquisition impacts. The divestiture impact, translation impact and total sales change are also provided for each segment.

In addition to these six operating business segments, 3M assigns certain costs to “Corporate and Unallocated,” which is presented separately in the preceding business segments table and in Note 17. Corporate and unallocated includes a variety of miscellaneous items, such as corporate investment gains and losses, certain derivative gains and losses, certain insurance-related gains and losses, certain litigation and environmental expenses, corporate restructuring charges and certain under- or over-absorbed costs (e.g. pension, stock-based compensation) that the Company may choose not to allocate directly to its business segments. Because this category includes a variety of miscellaneous items, it is subject to fluctuation on a quarterly and annual basis. The primary item driving higher 2011 expenses when compared to 2010 relates to pension and postretirement expense, as a portion of the 2011 increase in these expenses was not allocated directly to the six operating business segments. The primary items driving higher 2010 expenses when compared to 2009 relates to increased pension and postretirement expense, in addition to increased stock-based compensation expense.

As discussed in the preceding overview and results of operations section, the combination of restructuring actions and other special items significantly impacted 2009 results. There were no special items that impacted operating income in 2011 or 2010. The following table summarizes special items by business segment.

The following discusses total year results for 2011 compared to 2010, and also discusses 2010 compared to 2009, for each business segment.

Industrial and Transportation Business (34.0% of consolidated sales):

The Industrial and Transportation segment serves a broad range of markets, such as automotive original equipment manufacturer (OEM) and automotive aftermarket (auto body shops and retail), renewable energy, electronics, paper and packaging, food and beverage, and appliance. Industrial and Transportation products include tapes, a wide variety of coated and non-woven abrasives, adhesives, specialty materials, filtration products, energy control products, closure systems for personal hygiene products, acoustic systems products, and components and products that are used in the manufacture, repair and maintenance of automotive, marine, aircraft and specialty vehicles.

Year 2011 results:

Sales in Industrial and Transportation increased 19.5 percent to $10.1 billion. In local-currency terms, sales increased 15.9 percent, with 10.0 percent of this increase attributable to organic local-currency growth. Acquisitions increased sales by 5.9 percent, primarily driven by Winterthur and Alpha Beta (discussed below). Foreign currency impacts added 3.6 percent to 2011 sales growth. Geographically, local-currency sales increased in all major regions, led by Asia Pacific and Europe. Local-currency sales growth was broad-based across the portfolio, led by abrasives systems, renewable energy, aerospace and aircraft maintenance, industrial adhesives and tapes, and energy and advanced materials. In addition, despite the Japan and Thailand natural disasters, 3M also achieved growth in its automotive aftermarket and automotive OEM businesses.

3M continues to invest in its Industrial and Transportation business. In March 2011, 3M acquired a controlling interest in Winterthur via completion of a public tender offer. Winterthur, based in Zug, Switzerland, is a leading global supplier of precision grinding technology serving customers in the area of hard-to-grind precision applications in industrial, automotive, aircraft, and cutting tools. In addition, in February 2011, 3M completed its acquisition of the tape-related assets of Alpha Beta, a leading manufacturer of box sealing tape and masking tape headquartered in Taipei, Taiwan.

Operating income was $2.1 billion in 2011, 17.3 percent higher than 2010. 3M achieved operating income margins of 20.4 percent, even with continued investments to support growth.

Year 2010 results:

Sales in Industrial and Transportation increased 18.4 percent to $8.4 billion. In local-currency terms, sales increased 17.2 percent, driven almost entirely by organic volume. Foreign currency impacts added 1.2 percent to 2010 sales growth. Geographically, local-currency sales growth increased in all major geographic regions, led by Asia Pacific. Local-currency sales growth was broad-based across the portfolio, led by renewable energy, automotive OEM, energy and advanced materials, aerospace, abrasives systems, and industrial adhesives and tapes.

Operating income increased 43 percent to $1.8 billion in 2010, with operating income margins of 20.8 percent. In 2009, this business segment recorded charges of $89 million related to restructuring actions, with this charge comprised of employee-related liabilities for severance and benefits of $84 million and fixed asset impairments of $5 million.

Investment:

In March 2005, 3M’s automotive business completed the purchase of 19 percent of TI&M Beteiligungsgesellschaft mbH (TI&M) for approximately $55 million. TI&M is the parent company of I&T Innovation Technology Entwicklungsund Holding Aktiengesellschaft (I&T), an Austrian maker of flat flexible cable and circuitry. Pursuant to a

Shareholders Agreement, 3M marketed the firm’s flat flexible wiring systems for automotive interior applications to the global automotive market. I&T filed a petition for bankruptcy protection in August 2006. As part of its agreement to purchase the shares of TI&M, the Company was granted a put option, which gave the Company the right to sell back its entire ownership interest in TI&M to the other investors from whom 3M acquired its 19 percent interest. The put option became exercisable January 1, 2007. The Company exercised the put option and recovered approximately $25 million of its investment from one of the investors based in Belgium in February 2007. The other two TI&M investors from whom 3M purchased its shares have filed a bankruptcy petition in Austria. The Company has recovered approximately 6.7 million Euros through this bankruptcy process, which in addition to prior recoveries, results in a remaining investment balance of approximately 12 million Euros (approximately $15 million) as of December 31, 2011. The Company is pursuing recovery of the balance of its investment, first, from the bank that held the 3M purchase price paid to the two bankrupt investors and, to the extent not made whole, pursuant to the terms of the Share Purchase Agreement. The Company believes collection of its remaining investment is probable and, as a result, no impairment reserve has been recorded.

Health Care Business (17.0% of consolidated sales):

The Health Care segment serves markets that include medical clinics and hospitals, pharmaceuticals, dental and orthodontic practitioners, and health information systems. Products and services provided to these and other markets include medical and surgical supplies, skin health and infection prevention products, inhalation and transdermal drug delivery systems, dental and orthodontic products (oral care), health information systems, and food safety products.

Year 2011 results:

Health Care sales increased 11.5 percent to $5.0 billion. Local-currency sales increased 8.4 percent, including 3.8 percent from acquisitions. Acquisition growth primarily related to Arizant Inc., a leading manufacturer of patient warming solutions designed to prevent hypothermia in surgical settings. Currency impacts increased sales by 3.1 percent in Health Care. On a geographic basis, all regions posted positive sales growth. Asia Pacific, Latin America/Canada, and Europe all reported sales growth of 10 percent or more, while the U.S. grew at 9 percent. Local currency sales growth was led by the infection prevention, health information systems, food safety, skin and wound care, and oral care businesses. Sales in the drug-delivery systems business increased in the fourth quarter of 2011 compared to the same period in 2010, but were down slightly for total-year 2011 when compared to 2010.

Operating income in Health Care increased 9.3 percent in 2011 to $1.5 billion. Operating income margins were 29.6 percent, compared to 30.2 percent in 2010, with this decrease due in part to growth investments in the health information systems and infection prevention businesses. 3M has also been investing in emerging markets over the past couple of years to improve market penetration levels. The year-on-year decline in operating income margins was also due in part to sales declines in drug delivery systems. 3M’s long-term expectation is that Health Care operating income margins will be in the high 20’s, as 3M continues to invest to grow this business.

Year 2010 results:

Health Care local-currency sales increased 5.3 percent, including a benefit of 1.2 percent from acquisitions, primarily related to the Arizant Inc. acquisition in the fourth quarter (discussed above). Currency impacts increased sales by 0.3 percent. On a geographic basis, all regions posted positive local-currency sales growth, led by Asia Pacific and Latin America/Canada. Local currency sales growth was broad-based, led by skin and wound care, drug delivery systems, health information systems, infection prevention and oral care.

Operating income increased 1.1 percent to $1.4 billion, and operating income margins were 30.2 percent. Health Care recorded charges of $20 million related to restructuring actions in 2009, with this charge comprised of employee-related liabilities for severance and benefits. Lower year-on-year H1N1-related sales penalized both sales and operating income in 2010.

Consumer and Office Business (14.0% of consolidated sales):

The Consumer and Office segment serves markets that include consumer retail, office retail, home improvement, building maintenance and other markets. Products in this segment include office supply products, stationery products, construction and home improvement products (do-it-yourself), home care products, protective material products, certain consumer retail personal safety products, and consumer health care products.

Year 2011 results:

Sales in Consumer and Office increased 7.8 percent in 2011 to $4.2 billion, with all businesses posting positive sales growth. Local-currency sales increased 5.4 percent, which included 4.0 percent from organic growth and 1.4 percent from acquisitions. Acquisition growth was largely due to the October 2011 acquisition of the do-it-yourself and professional business of GPI Group and the April 2010 acquisition of the A-One branded label business and related operations. GPI is a manufacturer and marketer of home improvement products such as tapes, hooks, insulation and floor protection products and accessories. The addition of GPI’s products will expand 3M’s product portfolio in core and complementary categories in the construction and home improvement markets. A-One is the largest branded label business in Asia and the second largest worldwide. 3M also acquired Hybrivet Systems Inc. in the first quarter of 2011, a provider of instant-read products to detect lead and other contaminants and toxins. Foreign currency impacts contributed 2.4 percent to sales growth in the Consumer and Office segment. On a geographic basis, sales increased in all regions, led by Asia Pacific, Latin America/Canada and Europe, which all had sales growth rates in excess of 10 percent. U.S. sales also grew, albeit at a slower rate.

Consumer and Office operating income was flat when comparing 2011 to 2010, reflecting continued ongoing investments in developing economies in brand development and marketing and sales coverage. Even with these investments, Consumer and Office generated operating income margins of 20.2 percent.

In December 2011, 3M entered into a definitive agreement to acquire the Office and Consumer Products business of Avery Dennison Corp. for a total purchase price of approximately $550 million, subject to certain adjustments. The Office and Consumer Products business of Avery Dennison is a leading supplier of office and education products, including labels, binders, presentation products, filing and indexing products, writing instruments, and other office and home organization products. The transaction is expected to be completed in the second half of 2012, subject to customary closing conditions including any necessary regulatory approvals.

Year 2010 results:

Sales in Consumer and Office increased 11.0 percent in 2010 to $3.9 billion. Local-currency sales increased 10.0 percent, which included 7.1 percent from organic growth and 2.9 percent from acquisitions. Acquisition growth for 2010 was primarily comprised of the July 2009 acquisition of ACE® and related brands, which sells elastic bandage, supports and thermometer product lines through consumer channels in North America, and the April 2010 acquisition of the A-One branded label business (discussed above). In addition, the January 2010 acquisition of Incavas Industria de Cabos e Vassouras Ltda., a manufacturer of floor care products, contributed to acquisition sales growth. Foreign currency impacts added 1.0 percent to sales growth.
