Notes to Consolidated Financial Statements

(Unaudited)

NOTE 1.  Significant Accounting Policies

Basis of Presentation

The interim consolidated financial statements are unaudited but, in the opinion of management, reflect all adjustments necessary for a fair statement of the Company’s consolidated financial position, results of operations and cash flows for the periods presented. These adjustments consist of normal, recurring items. The results of operations for any interim period are not necessarily indicative of results for the full year. The interim consolidated financial statements and notes are presented as permitted by the requirements for Quarterly Reports on Form 10-Q.

As described in 3M’s Current Report on Form 8-K dated May 17, 2010 (which updated 3M’s 2009 Annual Report on Form 10-K) and 3M’s Quarterly Report on Form 10-Q for the period ended March 31, 2010, during the first quarter of 2010 the Company made certain product moves between its business segments in its continuing effort to drive growth by aligning businesses around markets and customers (Note 14). Segment information presented herein reflects the impact of these changes for all periods presented. This Quarterly Report on Form 10-Q should be read in conjunction with the Company’s consolidated financial statements and notes included in its Current Report on Form 8-K dated May 17, 2010.

Foreign Currency Translation

3M generally considers local currencies as the functional currencies outside the United States. However, under Accounting Standards Codification (ASC) 830, Foreign Currency Matters, the reporting currency of a foreign entity’s parent is assumed to be that entity’s functional currency when the economic environment of a foreign entity is highly inflationary—generally when its cumulative inflation is approximately 100 percent or more for the three years that precede the beginning of a reporting period. 3M has a subsidiary in Venezuela with operating income representing less than 1.0 percent of 3M’s consolidated operating income for both 2009 and the nine-month period ended September 30, 2010. As previously disclosed by the Company in Note 1 to the consolidated financial statements in 3M’s Current Report on Form 8-K dated May 17, 2010, 3M determined that the cumulative inflation rate of Venezuela in November 2009 exceeded 100 percent. Accordingly, the financial statements of the Venezuelan subsidiary were remeasured as if its functional currency were that of its parent beginning January 1, 2010.

Regulations in Venezuela require the purchase and sale of foreign currency to be made at official rates of exchange that are fixed from time to time by the Venezuelan government. Certain laws in the country, however, provided an exemption for the purchase and sale of certain securities and resulted in an indirect “parallel” market through which companies obtained foreign currency without having to purchase it from Venezuela’s Commission for the Administration of Foreign Exchange (CADIVI). In May 2010, the Venezuelan government took control of the previously freely-traded parallel market. The government-controlled rate that emerged under the new Transaction system for Foreign Currency Denominated Securities (SITME) is not as unfavorable as the previous parallel rate in comparison to the official rates. As previously disclosed, as of December 31, 2009 (prior to the change in functional currency of 3M’s Venezuelan subsidiary in January 2010), 3M changed to use of the parallel exchange rate for translation of the financial statements of its Venezuelan subsidiary. Beginning January 1, 2010, as discussed above, the financial statements of the Venezuelan subsidiary are remeasured as if its functional currency were that of its parent. This remeasurement utilized the parallel rate through May 2010 and the SITME rate thereafter.

The Company continues to monitor circumstances relative to its Venezuelan subsidiary. Other factors notwithstanding, the change in functional currency of this subsidiary and associated remeasurement beginning January 1, 2010 as a result of Venezuela’s economic environment will decrease net sales of the Venezuelan subsidiary by approximately two-thirds in 2010 in comparison to 2009 (based on exchange rates at 2009 year-end), but will not otherwise have a material impact on operating income and 3M’s consolidated results of operations.

Earnings per share

The difference in the weighted average 3M shares outstanding for calculating basic and diluted earnings per share attributable to 3M common shareholders is a result of the dilution associated with the Company’s stock-based compensation plans. Certain options outstanding under these stock-based compensation plans were not included in the computation of diluted earnings per share attributable to 3M common shareholders because they would not have had a dilutive effect (30.2 million average options for the three months ended September 30, 2010; 30.4 million average options for the nine months ended September 30, 2010; 43.0 million average options for the three months ended

6

September 30, 2009; 62.1 million average options for the nine months ended September 30, 2009). The conditions for conversion related to the Company’s “Convertible Notes” were not met (refer to 3M’s Current Report on Form 8-K dated May 17, 2010, Note 10 to the Consolidated Financial Statements, for more detail). If the conditions for conversion are met, 3M may choose to pay in cash and/or common stock; however, if this occurs, the Company has the intent and ability to settle this debt security in cash. Accordingly, there was no impact on diluted earnings per share attributable to 3M common shareholders. The computations for basic and diluted earnings per share follow:

New Accounting Standards

In June 2009, the Financial Accounting Standards Board (FASB) issued a new standard regarding the accounting for transfers of financial assets amending the existing guidance on transfers of financial assets to, among other things, eliminate the qualifying special-purpose entity concept, include a new unit of account definition that must be met for transfers of portions of financial assets to be eligible for sale accounting, clarify and change the derecognition criteria for a transfer to be accounted for as a sale, and require significant additional disclosure. For 3M, this standard was effective for new transfers of financial assets beginning January 1, 2010. Because 3M does not have significant transfers of financial assets, the adoption of this standard did not have a material impact on 3M’s consolidated results of operations or financial condition.

In June 2009, the FASB issued a new standard that revises the consolidation guidance for variable-interest entities. The modifications include the elimination of the exemption for qualifying special purpose entities, a new approach for determining who should consolidate a variable-interest entity, and changes to when it is necessary to reassess who should consolidate a variable-interest entity. For 3M, this standard was effective January 1, 2010. The adoption of this standard did not have a material impact on 3M’s consolidated results of operations or financial condition.

In October 2009, the FASB issued Accounting Standards Update (ASU) No. 2009-13, Multiple-Deliverable Revenue Arrangements—a consensus of the FASB Emerging Issues Task Force, that provides amendments to the criteria for separating consideration in multiple-deliverable arrangements. As a result of these amendments, multiple-deliverable revenue arrangements will be separated in more circumstances than under existing U.S. GAAP. The ASU does this by establishing a selling price hierarchy for determining the selling price of a deliverable. The selling price used for each deliverable will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. A vendor will be required to determine its best estimate of selling price in a manner that is consistent with that used to determine the price to sell the deliverable on a standalone basis. This ASU also eliminates the residual method of allocation and will require that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method, which allocates any discount in the overall arrangement proportionally to each deliverable based on its relative selling price. Expanded disclosures of qualitative and quantitative information regarding application of the multiple-deliverable revenue arrangement guidance are also required under the ASU. The ASU does not apply to arrangements for which industry specific allocation and measurement guidance exists, such as long-term construction contracts and software transactions. For 3M, ASU No. 2009-13 is effective beginning January 1, 2011. 3M may elect to adopt the provisions prospectively to new or materially modified arrangements beginning on the effective date or retrospectively for all periods presented. The Company is currently evaluating the impact of this standard on 3M’s consolidated results of operations and financial condition.

7

In October 2009, the FASB issued ASU No. 2009-14, Certain Revenue Arrangements That Include Software Elements—a consensus of the FASB Emerging Issues Task Force, that reduces the types of transactions that fall within the current scope of software revenue recognition guidance. Existing software revenue recognition guidance requires that its provisions be applied to an entire arrangement when the sale of any products or services containing or utilizing software when the software is considered more than incidental to the product or service. As a result of the amendments included in ASU No. 2009-14, many tangible products and services that rely on software will be accounted for under the multiple-element arrangements revenue recognition guidance rather than under the software revenue recognition guidance. Under the ASU, the following components would be excluded from the scope of software revenue recognition guidance:  the tangible element of the product, software products bundled with tangible products where the software components and non-software components function together to deliver the product’s essential functionality, and undelivered components that relate to software that is essential to the tangible product’s functionality. The ASU also provides guidance on how to allocate transaction consideration when an arrangement contains both deliverables within the scope of software revenue guidance (software deliverables) and deliverables not within the scope of that guidance (non-software deliverables). For 3M, ASU No. 2009-14 is effective beginning January 1, 2011. 3M may elect to adopt the provisions prospectively to new or materially modified arrangements beginning on the effective date or retrospectively for all periods presented. However, 3M must elect the same transition method for this guidance as that chosen for ASU No. 2009-13. The Company is currently evaluating the impact of this standard on 3M’s consolidated results of operations and financial condition.

In January 2010, the FASB issued ASU No. 2010-6, Improving Disclosures About Fair Value Measurements, that amends existing disclosure requirements under FASB Accounting Standards Codification™ (ASC) 820 by adding required disclosures about items transferring into and out of levels 1 and 2 in the fair value hierarchy; adding separate disclosures about purchases, sales, issuances, and settlements relative to level 3 measurements; and clarifying, among other things, the existing fair value disclosures about the level of disaggregation. For 3M this ASU is effective for the first quarter of 2010, except for the requirement to provide level 3 activity of purchases, sales, issuances, and settlements on a gross basis, which is effective beginning the first quarter of 2011. Additional disclosures required by this standard for 2010 are included in Note 11. Since this standard impacts disclosure requirements only, its adoption did not have a material impact on 3M’s consolidated results of operations or financial condition.

In April 2010, the FASB issued ASU No. 2010-17, Milestone Method of Revenue Recognition—a consensus of the FASB Emerging Issues Task Force that recognizes the milestone method as an acceptable revenue recognition method for substantive milestones in research or development arrangements. This standard would require its provisions be met in order for an entity to recognize consideration that is contingent upon achievement of a substantive milestone as revenue in its entirety in the period in which the milestone is achieved. In addition, this ASU would require disclosure of certain information with respect to arrangements that contain milestones. For 3M this standard would be required prospectively beginning January 1, 2011. The Company is currently evaluating the impact of this standard on 3M’s consolidated results of operations and financial condition.

NOTE 2.  Acquisitions

During the nine months ended September 30, 2010, 3M completed five business combinations. The purchase price paid for these business combinations (net of cash acquired), contingent consideration paid for pre-2009 business combinations, and the impact of other matters (net) during the nine months ended September 30, 2010 aggregated to $48 million. In addition, the Company recorded a financed liability of 1.7 billion Japanese Yen (approximately $18 million based on acquisition date exchange rates) as non-cash investing and financing activity associated with these acquisitions.

(1) In January 2010, 3M (Consumer and Office Business) purchased all of the outstanding shares of Incavas Industria de Cabos e Vassouras Ltda., a manufacturer of floor care products based in Rio Grande do Sul, Brazil.

(2) In April 2010, 3M (Consumer and Office Business) purchased a majority stake in the A-One branded label business and related operations, which is headquartered in Tokyo, Japan and has manufacturing, distribution and sales locations around Japan. The terms of this acquisition included embedded mirroring put and call options for a fixed price and five-year term with respect to the remaining minority shares. Accordingly, 3M recorded this business combination as an acquisition of all outstanding interests with a corresponding financed liability of 1.7 billion Japanese Yen relative to the embedded put/call option as of the acquisition date.

(3) In May 2010, 3M (Health Care Business) purchased certain assets of J.R. Phoenix Ltd., a manufacturer of hand hygiene and skin care products for health care and professional use based in Kitchener, Ontario, Canada.

8

(4) In June 2010, 3M (Industrial and Transportation Business) purchased all of the outstanding shares of MTI PolyFab Inc., a manufacturer of thermal and acoustic insulation for the aerospace industry. MTI PolyFab Inc. is based in Mississauga, Ontario, Canada.

(5) In July 2010, 3M (Safety, Security and Protection Services Business) purchased all of the outstanding shares of Dailys Limited, a supplier of non-woven disposable protective clothing, primarily chemical protective coveralls for industrial use. Dailys Limited is based in Ellesmere Port, United Kingdom.

Purchased identifiable intangible assets related to the acquisitions that closed in the first nine months of 2010 totaled $64 million and will be amortized on a straight-line basis over a weighted-average life of 9 years (lives ranging from 3 to 17 years). Acquired identifiable intangible assets for which significant assumed renewals or extensions of underlying arrangements impacted the determination of their useful lives were not material. Pro forma information related to the above acquisitions is not included because the impact on the Company’s consolidated results of operations is not considered to be material.

In addition to business combinations, 3M periodically acquires certain tangible and/or intangible assets and purchases interests in certain enterprises that do not otherwise qualify for accounting as business combinations. These transactions are largely reflected as additional asset purchase and investment activity.

Subsequent Events

The following events occurred in October 2010:

3M (Health Care Business) purchased all of the outstanding shares of Arizant Inc. for approximately $800 million, net of cash acquired, but inclusive of debt assumed and immediately paid. Arizant Inc., based in Eden Prairie, Minnesota, is a manufacturer of patient warming solutions designed to prevent hypothermia in surgical settings.

3M (Safety, Security and Protection Services Business) purchased all of the outstanding shares of Attenti Holdings S.A. for approximately $225 million, net of cash acquired, but inclusive of debt assumed and immediately paid. Attenti Holdings S.A., based in Tel Aviv, Israel, is a supplier of remote people-monitoring technologies used for offender-monitoring applications and to assist eldercare facilities in monitoring and enhancing the safety of patients.

3M (Safety, Security and Protection Services Business) acquired a controlling interest in Cogent Inc. (representing 72 percent of outstanding shares on a fully diluted basis) for approximately $535 million, net of cash acquired, via a tender offer. Cogent Inc., based in Pasadena, California, is a provider of finger, palm, face and iris biometric systems for governments, law enforcement agencies, and commercial enterprises. 3M intends to acquire the remaining publicly held shares of Cogent (other than shares as to which appraisal rights are properly exercised) for $10.50 per share (or approximately $265 million assuming no appraisal rights are exercised) in a second-step merger that will be completed following the approval of the merger at a meeting of Cogent shareholders to be held in the fourth quarter of 2010. As a result of the purchase of shares in the tender offer, 3M has sufficient voting power to approve the merger at such meeting without the vote of any other Cogent shareholders. The aggregate purchase price of approximately $800 million (including the portion of the purchase price expected to be paid on completion of the second-step merger), net of cash acquired, reflects approximately $380 million of marketable securities held by Cogent as of the October 2010 date when 3M acquired its controlling interest in Cogent.

The purchase price accounting for these October 2010 business combinations has not yet been finalized; thus, certain disclosures are not required. Pro forma information related to these October 2010 business combinations is not included because the impact on the Company’s consolidated results of operations is not considered to be material.

NOTE 3.  Goodwill and Intangible Assets

Purchased goodwill related to the five acquisitions which closed in the first nine months of 2010 totaled $43 million, less than $1 million of which is deductible for tax purposes. The acquisition activity in the following table also includes the impacts of contingent consideration for pre-2009 acquisitions, which increased goodwill by $1 million. The amounts in the “Translation and other” column in the following table primarily relate to changes in foreign currency exchange rates. The goodwill balance by business segment as of December 31, 2009 and September 30, 2010, follow:

Goodwill

	Dec. 31,							Sept. 30,
	2009		Acquisition		Translation			2010
(Millions)	Balance		activity		and other			Balance

Electro and Communications	677		—		(17		)	660
Total Company	$	5,832	$	44	$	23		$	5,899

Accounting standards require that goodwill be tested for impairment annually and between annual tests in certain circumstances such as a change in reporting units or the testing of recoverability of a significant asset group within a reporting unit. At 3M, reporting units generally correspond to a division.

As discussed in Note 14, effective in the first quarter of 2010, 3M made certain product moves between its business segments, with the resulting impact reflected in the goodwill balances by business segment above for all periods presented. For any product moves that resulted in reporting unit changes, the Company applied the relative fair value method to determine the impact to reporting units. During the first quarter of 2010, the Company completed its assessment of any potential goodwill impairment for reporting units impacted by this new structure and determined that no impairment existed.

Acquired Intangible Assets

For the nine months ended September 30, 2010, intangible assets (excluding goodwill) acquired through business combinations increased balances by $64 million. Balances are also impacted by changes in foreign currency exchange rates. The carrying amount and accumulated amortization of acquired intangible assets as of September 30, 2010, and December 31, 2009, follow:

	Sept. 30,			Dec. 31,
(Millions)	2010			2009
Patents	$	447		$	457
Other amortizable intangible assets (primarily tradenames and customer related intangibles)	1,562			1,519
Non-amortizable intangible assets (tradenames)	126			138
Total gross carrying amount	$	2,135		$	2,114
Accumulated amortization – patents	(341		)	(339		)
Accumulated amortization – other	(515		)	(433		)
Total accumulated amortization	(856		)	(772		)
Total intangible assets – net	$	1,279		$	1,342

Amortization expense for acquired intangible assets for the three-month and nine-month periods ended September 30, 2010 and 2009 follows:

	Three months ended				Nine months ended
	Sept. 30,				Sept. 30,
(Millions)	2010		2009		2010		2009
Amortization expense	$	44	$	47	$	130	$	134

The table below shows expected amortization expense for acquired amortizable intangible assets recorded as of September 30, 2010:

(Millions)	LastQuarter2010		2011		2012		2013		2014		2015		After2015
Amortization expense	$	37	$	142	$	134	$	126	$	115	$	104	$	495

The expected amortization expense is an estimate. Actual amounts of amortization expense may differ from estimated amounts due to additional intangible asset acquisitions, changes in foreign currency exchange rates, impairment of intangible assets, accelerated amortization of intangible assets and other events. 3M expenses the costs incurred to renew or extend the term of intangible assets.

NOTE 4.  Restructuring Actions and Exit Activities

Restructuring actions and exit activities generally include significant actions involving employee-related severance charges, contract termination costs, and impairment of assets associated with such actions.

Employee-related severance charges are largely based upon distributed employment policies and substantive severance plans and are reflected in the quarter in which management approves the associated actions, the actions are probable, and the amounts are estimable. Severance amounts for which affected employees were required to render service in order to receive benefits at their termination dates were measured at the date such benefits were communicated to the applicable employees and recognized as expense over the employees’ remaining service periods.

Contract termination and other charges primarily reflect costs to terminate a contract before the end of its term (measured at fair value at the time the Company provided notice to the counterparty) or costs that will continue to be incurred under the contract for its remaining term without economic benefit to the Company. Asset impairment charges related to intangible assets and property, plant and equipment reflect the excess of the assets’ carrying values over their fair values.

The following provides information concerning the Company’s 2009/2008 restructuring actions.

2009 and 2008 Restructuring Actions:

During the fourth quarter of 2008 and the first nine months of 2009, management approved and committed to undertake certain restructuring actions. Due to the rapid decline in global business activity in the fourth quarter of 2008 and into the first three quarters of 2009, 3M aggressively reduced its cost structure and rationalized several facilities, including manufacturing, technical and office facilities. These actions included all geographies, with particular attention in the developed areas of the world that have and are experiencing large declines in business activity, and included the following:

·During the fourth quarter of 2008, 3M announced the elimination of more than 2,400 positions. Of these employment reductions, about 31 percent were in the United States, 29 percent in Europe, 24 percent in Latin America and Canada, and 16 percent in the Asia Pacific area. These restructuring actions resulted in a fourth-quarter 2008 pre-tax charge of $229 million, with $186 million for employee-related items/benefits and other, and $43 million related to fixed asset impairments. The preceding charges were recorded in cost of sales ($84 million), selling, general and administrative expenses ($135 million), and research, development and related expenses ($10 million). Cash payments in 2008 related to this restructuring were not material.

·During the first quarter of 2009, 3M announced the elimination of approximately 1,200 positions. Of these employment reductions, about 43 percent were in the United States, 36 percent in Latin America, 16 percent in Europe and 5 percent in the Asia Pacific area. These restructuring actions resulted in a first-quarter 2009 pre-tax charge of $67 million, with $61 million for employee-related items/benefits and $6 million related to fixed asset impairments. The preceding charges were recorded in cost of sales ($17 million), selling, general and administrative expenses ($47 million), and research, development and related expenses ($3 million).

·During the second quarter of 2009, 3M announced the permanent reduction of approximately 900 positions, the majority of which were concentrated in the United States, Western Europe and Japan. In the United States, another 700 people accepted a voluntary early retirement incentive program offer, which resulted in a $21 million non-cash charge. Of these aggregate employment reductions, about 66 percent were in the United States, 17 percent in the Asia Pacific area, 14 percent in Europe and 3 percent in Latin America and Canada. These restructuring actions in total resulted in a second-quarter 2009 pre-tax charge of $116 million, with $103 million for employee-related items/benefits and $13 million related to fixed asset impairments. The preceding charges were recorded in cost of sales ($68 million), selling, general and administrative expenses ($44 million), and research, development and related expenses ($4 million).

·During the third quarter of 2009, 3M announced the elimination of approximately 200 positions, with the majority of those occurring in Western Europe and, to a lesser extent, the United States. These restructuring actions, including a non-cash charge related to a pension settlement in Japan, resulted in a third-quarter 2009 net pre-tax charge of $26 million for employee-related items/benefits and other, which is net of $7 million of

11

adjustments to prior 2008 and 2009 restructuring actions. The preceding charges were recorded in cost of sales ($25 million) and research, development and related expenses ($1 million).

Components of these restructuring actions for the first three quarters of 2009 and a roll-forward of associated balances from December 31, 2009 follow below:

Reclassification adjustments are made to avoid double counting in comprehensive income items that are also recorded as part of net income. 3M had no material reclassification adjustments attributable to noncontrolling interest. As disclosed in Note 9, for the three and nine months ended September 30, 2010, $77 million pre-tax ($48 million after tax) and $231 million pre-tax ($146 million after tax), respectively, were reclassified to earnings from accumulated other comprehensive income attributable to 3M to pension and postretirement expense in the income statement. For the three and nine months ended September 30, 2009, $36 million pre-tax ($23 million after tax) and $106 million pre-tax ($68 million after tax), respectively, were reclassified to earnings. These pension and postretirement expense amounts are shown in the table in Note 9 as amortization of transition (asset) obligation, amortization of prior service cost (benefit) and amortization of net actuarial (gain) loss. In addition, reclassification adjustments include the third quarter 2009 Japan pension settlement as discussed in Note 9. Reclassifications to earnings from accumulated other comprehensive income for debt and equity securities, which primarily include marketable securities, were not material for the three and

15

nine months ended September 30, 2010 and 2009. Refer to Note 10 for a table that recaps pre-tax cash flow hedging instruments reclassifications. Income taxes are not provided for foreign currency translation relating to permanent investments in international subsidiaries, but tax effects within cumulative translation do include impacts from items such as net investment hedge transactions.

Purchase of Subsidiary Shares and Transfers of Ownership Interests Involving Non-Wholly Owned Subsidiaries

During the second half of 2009 and the first half of 2010, 3M effected a purchase of subsidiary shares and transfers of ownership interests to align activities in Japan and to simplify the Company’s ownership structure. As a result of these activities, beginning in June 2010 the Company has a wholly owned subsidiary in the region in addition to its majority owned Sumitomo 3M Limited entity (Sumitomo 3M). Because the Company retained its controlling interest in the subsidiaries involved, these activities resulted in changes to 3M Company shareholders’ equity and noncontrolling interest. These activities included the following:

·During the second half of 2009, a wholly owned subsidiary that, in turn, owned a portion of the Company’s majority owned Sumitomo 3M, was transferred to another subsidiary (referred to herein as 3M HC) that was majority, rather than wholly, owned. Sumitomo 3M also owned a portion of 3M HC. As a result of the transaction, 3M’s effective ownership in Sumitomo 3M was reduced from 75 percent to 71.5 percent. The transfer resulted in a decrease in 3M Company shareholders’ equity and an increase in noncontrolling interest of $81 million in the second half of 2009.

·During the first quarter of 2010, majority owned 3M HC which, as a result of the transfer above owned a portion of the Company’s majority owned Sumitomo 3M, transferred this interest to Sumitomo 3M. In addition, Sumitomo 3M purchased a portion of its shares held by its noncontrolling interest, Sumitomo Electric Industries, Ltd. (SEI), by paying cash of 5.8 billion Japanese Yen and entering into a note payable to SEI of 17.4 billion Japanese Yen (approximately $63 million and $188 million, respectively, based on applicable exchange rates at that time). As a result of these transactions, 3M’s effective ownership in Sumitomo 3M was increased from 71.5 percent to 75 percent. The cash paid as a result of the purchase of Sumitomo 3M shares from SEI was classified as an investing activity in the consolidated statement of cash flows. The remainder of the purchase financed by the note payable to SEI was considered non-cash investing and financing activity in the first quarter of 2010. These transactions resulted in an increase in 3M Company shareholders’ equity of $22 million and a decrease in noncontrolling interest of $278 million in the first quarter of 2010.

·During the second quarter of 2010, majority owned Sumitomo 3M transferred its interest in 3M HC to 3M HC. As a result of this transaction, 3M HC became wholly owned by the Company. The transfer resulted in an increase in 3M Company shareholders’ equity and a decrease in noncontrolling interest of $24 million in the second quarter of 2010.

Additionally, 3M acquired the remaining noncontrolling interest of a previously majority owned subsidiary for an immaterial amount during the first half of 2010.  The following table summarizes the effects of these transactions on equity attributable to 3M Company shareholders for the respective periods.

NOTE 6.  Income Taxes

The Company files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years before 2002.

The IRS completed its field examination of the Company’s U.S. federal income tax returns for the years 2005 through 2007 in the fourth quarter of 2009. The Company has protested certain IRS positions within these tax years and has entered into the administrative appeals process with the IRS during the first quarter of 2010. During the first quarter of 2010, the IRS completed its field examination of the Company’s U.S. federal income tax return for the 2008 year. The Company has protested certain IRS positions within this tax year and has entered into the administrative appeals

16

process with the IRS during the second quarter of 2010. Currently, the Company is under examination by the IRS for its U.S. federal income tax returns for the years 2009 and 2010. It is anticipated that the IRS will complete its examination of the Company for 2009 by the end of the first quarter of 2011, and for 2010 by the end of the first quarter of 2012. As of September 30, 2010, the IRS has not proposed any significant adjustments to the Company’s tax positions for which the Company is not adequately reserved.

During the first quarter of 2010, the Company paid the agreed upon assessments for the 2005 tax year. During the second quarter of 2010, the Company paid the agreed upon assessments for the 2008 tax year. Payments relating to other proposed assessments arising from the 2005 through 2010 examinations may not be made until a final agreement is reached between the Company and the IRS on such assessments or upon a final resolution resulting from the administrative appeals process or judicial action. In addition to the U.S. federal examination, there is also limited audit activity in several U.S. state and foreign jurisdictions.

3M anticipates changes to the Company’s uncertain tax positions due to the closing of the various audit years mentioned above. Currently, the Company is not able to reasonably estimate the amount by which the liability for unrecognized tax benefits will increase or decrease during the next 12 months as a result of the ongoing income tax authority examinations. The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of September 30, 2010 and December 31, 2009, respectively, are $391 million and $425 million.

The Company recognizes interest and penalties accrued related to unrecognized tax benefits in tax expense. The Company recognized in the consolidated statement of income on a gross basis approximately $4 million and $13 million of expense for the three months ended September 30, 2010 and September 30, 2009, respectively, and approximately $5 million of benefit and $19 million expense for the nine months ended September 30, 2010 and September 30, 2009, respectively. At September 30, 2010 and December 31, 2009, accrued interest and penalties in the consolidated balance sheet on a gross basis were $52 million and $53 million, respectively. Included in these interest and penalty amounts are interest and penalties related to tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period would not affect the annual effective tax rate, but would accelerate the payment of cash to the taxing authority to an earlier period.

Under a Federal program that was established to encourage companies to provide retiree prescription drug coverage, many companies, including 3M, received a tax-advantaged subsidy. The tax advantage of the subsidy was eliminated by the Patient Protection and Affordable Care Act (H.R. 3590), including modifications included in the Health Care and Education Reconciliation Act of 2010 (collectively, the “Act’), which were enacted in March 2010. Although the elimination of this tax advantage does not take effect until 2013 under the Act, 3M was required to recognize the full accounting impact in its financial statements in the period in which the Act was signed. Because future anticipated retiree health care liabilities and related tax subsidies are already reflected in 3M’s financial statements, the change in law resulted in a reduction of the value of the company’s deferred tax asset related to the subsidy. This reduction in value resulted in a one-time non-cash income tax charge to 3M’s earnings in the first quarter of 2010 of approximately $84 million, or 11 cents per diluted share.

While the preceding item increased the effective tax rate, the most significant item that decreased the effective tax rate in the first, second, and third quarters of 2010 related to international taxes. This was due primarily to the 2010 tax benefits resulting from the corporate alignment transactions that allowed the Company to increase its ownership of a foreign subsidiary. The transactions are described in the section of Note 5 entitled “Purchase of Subsidiary Shares and Transfers of Ownership Interest Involving Non-Wholly Owned Subsidiaries”.

The provision for income taxes is determined using the asset and liability approach. Under this approach, deferred income taxes represent the expected future tax consequences of temporary differences between the carrying amounts and tax basis of assets and liabilities. The Company records a valuation allowance to reduce its deferred tax assets when uncertainty regarding their realizability exists. As of September 30, 2010 and December 31, 2009, the ending balance of the Company’s valuation allowance on its deferred tax assets totaled $98 million and $23 million, respectively.

NOTE 7.  Marketable Securities

The Company invests in agency securities, corporate securities, asset-backed securities, treasury securities and other securities. The following is a summary of amounts recorded on the Consolidated Balance Sheet for marketable securities (current and non-current).

Classification of marketable securities as current or non-current is dependent upon management’s intended holding period, the security’s maturity date and liquidity considerations based on market conditions. If management intends to hold the securities for longer than one year as of the balance sheet date, they are classified as non-current. At September 30, 2010, gross unrealized losses totaled approximately $9 million (pre-tax), while gross unrealized gains totaled approximately $6 million (pre-tax). At December 31, 2009, gross unrealized losses totaled approximately $12 million (pre-tax), while gross unrealized gains totaled approximately $3 million (pre-tax). Gross realized gains and losses on sales or maturities of marketable securities for the first nine months of 2010 and 2009 were not material. Cost of securities sold use the first in, first out (FIFO) method. Since these marketable securities are classified as available-for-sale securities, changes in fair value will flow through other comprehensive income, with amounts reclassified out of other comprehensive income into earnings upon sale or “other-than-temporary” impairment.

3M reviews impairments associated with its marketable securities in accordance with the measurement guidance provided by ASC 320, Investments-Debt and Equity Securities, when determining the classification of the impairment as “temporary” or “other-than-temporary”. A temporary impairment charge results in an unrealized loss being recorded in the other comprehensive income component of shareholders’ equity. Such an unrealized loss does not reduce net income attributable to 3M for the applicable accounting period because the loss is not viewed as other-than-temporary. The factors evaluated to differentiate between temporary and other-than-temporary include the projected future cash flows, credit ratings actions, and assessment of the credit quality of the underlying collateral, as well as other factors.

The balance at September 30, 2010 for marketable securities and short-term investments by contractual maturity are shown below. Actual maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

(Millions)	Sept. 30, 2010
Due in one year or less	$	959
Due after one year through three years	767
Due after three years through five years	71
Due after five years	33
Total marketable securities	$	1,830

3M has a diversified marketable securities portfolio of $1.830 billion as of September 30, 2010. Within this portfolio, current and long-term asset-backed securities (estimated fair value of $661 million) are primarily comprised of interests in automobile loans and credit cards. At September 30, 2010, the asset-backed securities credit ratings were AAA or A-1.

3M’s marketable securities portfolio includes auction rate securities that represent interests in investment grade credit default swaps; however, currently these holdings comprise less than one percent of this portfolio. The estimated fair value of auction rate securities are $6 million and $5 million as of September 30, 2010 and December 31, 2009, respectively. Gross unrealized losses within accumulated other comprehensive income related to auction rate securities totaled $7 million (pre-tax) and $8 million (pre-tax) as of September 30, 2010 and December 31, 2009, respectively. As of September 30, 2010, auction rate securities associated with these balances have been in a loss position for more than 12 months. Since the second half of 2007, these auction rate securities failed to auction due to sell orders exceeding buy orders. Liquidity for these auction-rate securities is typically provided by an auction process that resets the applicable interest rate at pre-determined intervals, usually every 7, 28, 35, or 90 days. The funds associated with failed auctions will not be accessible until a successful auction occurs or a buyer is found outside of the auction process. Refer to Note 11 for a table that reconciles the beginning and ending balances of auction rate securities.

NOTE 8.  Long-Term Debt and Short-Term Borrowings

During the first quarter of 2010, the Company entered into a floating rate note payable of 17.4 billion Japanese Yen (approximately $188 million based on applicable exchange rates at that time) in connection with the purchase of additional interest in the Company’s Sumitomo 3M Limited subsidiary as discussed in Note 5. This note is due in three equal installments of 5.8 billion Japanese Yen, with one installment paid on September 30, 2010, and the remaining installments due March 30, 2011 and September 30, 2011. Interest accrues on the note based on the three-month Tokyo Interbank Offered Rate (TIBOR) plus 40 basis points.

During the second quarter of 2010, the Company recorded a five-year financed liability of 1.7 billion Japanese Yen (approximately $18 million based on applicable exchange rates at that time) as part of the consideration associated with 3M’s acquisition of the A-One branded label business and related operations discussed in Note 2. The Company records interest on this liability at an annual rate of approximately 1%.

In July 2007, in connection with the issuance of a seven-year Eurobond for an amount of 750 million Euros, the Company completed a fixed-to-floating interest rate swap on a notional amount of 400 million Euros as a fair value hedge of a portion of the fixed interest rate Eurobond obligation. In August 2010, the Company terminated 150 million Euros of the notional amount of this swap. As a result, the notional amount remaining after the partial termination is 250 million Euros. The termination of a portion of this swap did not impact the terms of the remaining portion.

For the nine months ended September 30, 2010, the Company contributed $392 million to its U.S. and international pension plans and $39 million to its postretirement plans. During the fourth quarter of 2010, the Company expects to contribute approximately $100 million to its U.S. and international pension and postretirement plans. The Company does not have a required minimum pension contribution obligation for its U.S. plans in 2010. However, the Company is considering making an additional discretionary contribution of $700 million in cash to its pension plans in either the fourth quarter of 2010 or first quarter of 2011, assuming that both September 30, 2010 discount rates hold and that September-to-date 2010 asset rate of return performance levels hold. The actual contribution may differ. If rates of return or discount rates become more favorable, 3M would likely contribute much less than this amount. The amount of the anticipated discretionary pension contribution could vary significantly depending on the U.S. plans’ funded status and the anticipated tax deductibility of the contribution. Future contributions will also depend on market conditions, interest rates and other factors. 3M’s annual measurement date for pension and postretirement assets and liabilities is December 31 each year, which is also the date used for the related annual measurement assumptions.

In the fourth quarter of 2010, the Company approved and communicated various changes to its U.S. postretirement benefit plans.  The Company will be providing eligible participants with a savings account benefits-based plan, which replaces the current 3M Retiree Medical Plan. The savings account benefits-based plan can be used to help pay for medical premiums or qualified medical expenses. These changes become effective beginning January 1, 2013, for all Medicare eligible retirees and their Medicare eligible dependents and January 1, 2015, for all non-Medicare eligible retirees and their eligible dependents. These changes are expected to increase the 2010 accumulated benefit obligation by $65 million.

In June 2010, 3M’s Brazilian subsidiary received approval from the government in Brazil to freeze its defined benefit pension plan. Effective March 31, 2010, participants in this subsidiary’s pension plan no longer accrue additional pension benefits. As a result, the Company recorded a $22 million curtailment gain in the second quarter of 2010.

In April 2009, the Company offered a voluntary early retirement incentive program to certain eligible participants of its U.S. pension plans who meet age and years of pension service requirements. The eligible participants who accepted the offer and retired by June 1, 2009 received an enhanced pension benefit. Pension benefits were enhanced by adding one additional year of pension service and one additional year of age for certain benefit calculations. Approximately 700 participants accepted the offer and retired by June 1, 2009. As a result the Company incurred a $21 million charge related to these special termination benefits in the second quarter of 2009.

During 2009, 3M Sumitomo (Japan) experienced a higher number of retirements than normal, largely due to early retirement incentive programs, which required eligible employees who elected to leave the Company to retire by September 2009. Participants in the Japan pension plan had the option of receiving cash lump sum payments when exiting the plan, which a number of participants exiting the pension plan elected to receive. In accordance with ASC 715, Compensation — Retirement Benefits, settlement accounting is required when the lump sum distributions in a year are greater than the sum of the annual service and interest costs. Due to the large number of lump sum payment elections, the Company incurred a $13 million settlement charge in the third quarter of 2009. The Company remeasured the funded status of the Japan pension plan as of September 30, 2009.

3M was informed during the first quarter of 2009 that the general partners of WG Trading Company, in which 3M’s benefit plans hold limited partnership interests, are the subject of a criminal investigation as well as civil proceedings by the SEC and CFTC (Commodity Futures Trading Commission). As of December 31, 2009 these holdings represented less than 2 percent of 3M’s fair value of total plan assets. The court appointed receiver has taken control of WG Trading Company and other entities controlled by its general partners, and further redemptions of limited partnership interests are restricted pending court proceedings. The amount that 3M’s benefit plans may recover from their investments in WG Trading Company may be lower than the value estimated on the last annual pension and postretirement measurement date of December 31, 2009. If this occurs, the primary impact of any changes in the asset valuation will be recognized on the next annual pension and postretirement measurement date of December 31, 2010. 3M currently believes that the resolution of these events will not have a material adverse effect on the consolidated financial position of the Company. The Company has insurance that it believes, based on what is currently known, is applicable to a portion of this potential decrease in asset value.

NOTE 10.  Derivatives

The Company uses interest rate swaps, currency swaps, commodity price swaps, and forward and option contracts to manage risks generally associated with foreign exchange rate, interest rate and commodity price fluctuations. The information that follows explains the various types of derivatives and financial instruments used by 3M, how and why 3M uses such instruments, how such instruments are accounted for, and how such instruments impact 3M’s financial position and performance.

Additional information with respect to the impacts on other comprehensive income of nonderivative hedging and derivative instruments is included in Note 5. Additional information with respect to the fair value of derivative instruments is included in Note 11.  References to information regarding derivatives and/or hedging instruments associated with the Company’s long-term debt are also made in Note 8 herein and in Note 10 to the Consolidated Financial Statements in 3M’s Current Report on Form 8-K dated May 17, 2010.

Types of Derivatives/Hedging Instruments and Inclusion in Income/Other Comprehensive Income

Cash Flow Hedges:

For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period during which the hedged transaction affects earnings.  Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.

Cash Flow Hedging - Foreign Currency Forward and Option Contracts: The Company enters into foreign exchange forward and option contracts to hedge against the effect of exchange rate fluctuations on cash flows denominated in foreign currencies and certain intercompany financing transactions. These transactions are designated as cash flow hedges. The settlement or extension of these derivatives will result in reclassifications (from accumulated other comprehensive income) to earnings in the period during which the hedged transactions affect earnings. Generally, 3M dedesignates these cash flow hedge relationships in advance of the occurrence of the forecasted transaction. The portion of gains or losses on the derivative instrument previously accumulated in other comprehensive income for dedesignated hedges remains in

21

accumulated other comprehensive income until the forecasted transaction occurs. Changes in the value of derivative instruments after dedesignation are recorded in earnings and are included in the Derivatives Not Designated as Hedging Instruments section below. Hedge ineffectiveness and the amount excluded from effectiveness testing recognized in income on cash flow hedges were not material for the three and nine month periods ended September 30, 2010 and 2009. The maximum length of time over which 3M hedges its exposure to the variability in future cash flows for a majority of the forecasted transactions is 12 months and, accordingly, at September 30, 2010, the majority of the Company’s open foreign exchange forward and option contracts had maturities of one year or less. The dollar equivalent gross notional amount of the Company’s foreign exchange forward and option contracts designated as cash flow hedges at September 30, 2010 was approximately $3.5 billion.

Cash Flow Hedging - Commodity Price Management: The Company manages commodity price risks through negotiated supply contracts, price protection agreements and forward physical contracts. The Company uses commodity price swaps relative to natural gas as cash flow hedges of forecasted transactions to manage price volatility. The related mark-to-market gain or loss on qualifying hedges is included in other comprehensive income to the extent effective, and reclassified into cost of sales in the period during which the hedged transaction affects earnings. Generally, the length of time over which 3M hedges its exposure to the variability in future cash flows for its forecasted natural gas transactions is 12 months. No significant commodity cash flow hedges were discontinued and hedge ineffectiveness was not material for the three and nine month periods ended September 30, 2010 and 2009. The dollar equivalent gross notional amount of the Company’s natural gas commodity price swaps designated as cash flow hedges at September 30, 2010 was $39 million.

The location in the consolidated statements of income and comprehensive income and amounts of gains and losses related to derivative instruments designated as cash flow hedges are as follows. Reclassifications of amounts from accumulated other comprehensive income into income include accumulated gains (losses) on dedesignated hedges at the time earnings are impacted by the forecasted transaction.

As of September 30, 2010, the Company had a balance of $25 million associated with the after tax net unrealized loss associated with cash flow hedging instruments recorded in accumulated other comprehensive income. 3M expects to reclassify to earnings over the next 12 months a majority of this balance (with the impact offset by cash flows from underlying hedged items).

Fair Value Hedges:

For derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivatives as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings.

Fair Value Hedging - Interest Rate Swaps: The Company manages interest expense using a mix of fixed and floating rate debt. To help manage borrowing costs, the Company may enter into interest rate swaps. Under these arrangements, the Company agrees to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount. The mark-to-market of these fair value hedges is recorded as gains or losses in interest expense and is offset by the gain or loss of the underlying debt instrument, which also is recorded in interest expense. These fair value hedges are highly effective and, thus, there is no impact on earnings due to hedge ineffectiveness. The dollar equivalent (based on inception date foreign currency exchange rates) gross notional amount of the Company’s interest rate swaps at September 30, 2010 was $1.1 billion.

At September 30, 2010, the Company had interest rate swaps designated as fair value hedges of underlying fixed rate obligations. In November 2006, the Company entered into a $400 million fixed-to-floating interest rate swap concurrent with the issuance of the three-year medium-term note due in 2009. In July 2007, in connection with the issuance of a seven-year Eurobond for an amount of 750 million Euros, the Company completed a fixed-to-floating interest rate swap on a notional amount of 400 million Euros as a fair value hedge of a portion of the fixed interest rate Eurobond obligation. In August 2010, the Company terminated 150 million Euros of the notional amount of this swap. As a result, a gain of 18 million Euros, recorded as part of the balance of the underlying debt, will be amortized over this debt’s remaining life. The Company also has two fixed-to-floating interest rate swaps with an aggregate notional amount of $800 million designated as fair value hedges of the fixed interest rate obligation under the existing $800 million, three-year, 4.50% notes issued in October 2008.

Fair Value Hedging — Foreign Currency: In November 2008, the Company entered into foreign currency forward contracts to purchase Japanese Yen, Pound Sterling, and Euros with a notional amount of $255 million at the contract rates. These contracts were designated as fair value hedges of a U.S. dollar tax obligation. These fair value hedges matured in early January 2009. The mark-to-market of these forward contracts was recorded as gains or losses in tax expense and was offset by the gain or loss on the underlying tax obligation, which also was recorded in tax expense. Changes in the value of these contracts in 2009 through their maturity were not material.

The location in the consolidated statements of income and amounts of gains and losses related to derivative instruments designated as fair value hedges and similar information relative to the hedged items are as follows:

Net Investment Hedges:

As circumstances warrant, the Company uses cross currency swaps, forwards and foreign currency denominated debt to hedge portions of the Company’s net investments in foreign operations. For hedges that meet the effectiveness requirements, the net gains or losses attributable to changes in spot exchange rates are recorded in cumulative translation within other comprehensive income. The remainder of the change in value of such instruments is recorded in earnings. Recognition in earnings of amounts previously recorded in cumulative translation is limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operation. At September 30, 2010, there were no cross currency swaps and foreign currency forward contracts designated as net investment hedges.

In November 2006, the Company entered into a three-year floating-to-floating cross currency swap with a notional amount of $200 million. This transaction was a partial hedge of the Company’s net investment in its European subsidiaries. This swap converted U.S. dollar-based variable interest payments to Euro-based variable interest payments associated with the notional amount. This swap matured in November 2009.

In September 2006, the Company entered into a three-year floating-to-floating cross currency swap with a notional amount of $300 million. This transaction was a partial hedge of the Company’s net investment in its Japanese subsidiaries. This swap converted U.S. dollar-based variable interest payments to yen-based variable interest payments associated with the notional amount. This swap matured in September 2009.

In addition to the derivative instruments used as hedging instruments in net investment hedges, 3M also uses foreign currency denominated debt as nonderivative hedging instruments in certain net investment hedges. In July and December 2007, the Company issued seven-year fixed rate Eurobond securities for amounts of 750 million Euros and 275 million Euros, respectively. 3M designated each of these Eurobond issuances as hedging instruments of the Company’s net investment in its European subsidiaries.

The location in the consolidated statements of income and comprehensive income and amounts of gains and losses related to derivative and nonderivative instruments designated as net investment hedges are as follows. There were no reclassifications of the effective portion of net investment hedges out of accumulated other comprehensive income into income for the periods presented in the table below.

Derivatives Not Designated as Hedging Instruments:

Derivatives not designated as hedging instruments include dedesignated foreign currency forward and option contracts that formerly were designated in cash flow hedging relationships (as referenced in the Cash Flow Hedges section above). In addition, 3M enters into foreign currency forward contracts and commodity price swaps to offset, in part, the impacts of certain intercompany activities (primarily associated with intercompany licensing arrangements) and fluctuations in costs associated with the use of certain precious metals, respectively. These derivative instruments are not designated in hedging relationships; therefore, fair value gains and losses on these contracts are recorded in earnings. The dollar equivalent gross notional amount of these forward, option and swap contracts not designated as hedging instruments totaled $961 million as of September 30, 2010. The Company does not hold or issue derivative financial instruments for trading purposes.

The location in the consolidated statements of income and amounts of gains and losses related to derivative instruments not designated as hedging instruments are as follows:

Currency Effects and Credit Risk

Currency Effects: 3M estimates that year-on-year currency effects, including hedging impacts, decreased net income attributable to 3M by approximately $15 million for the three months ended September 30, 2010 and increased net income attributable to 3M by approximately $15 million for the nine months ended September 30, 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. 3M estimates that year-on-year derivative and other transaction gains and losses decreased net income attributable to 3M by approximately $30 million for the three months ended September 30, 2010 and decreased net income attributable to 3M by approximately $110 million for the nine months ended September 30, 2010.

Credit risk: The Company is exposed to credit loss in the event of nonperformance by counterparties in interest rate swaps, currency swaps, commodity price swaps, and forward and option contracts. However, the Company’s risk is limited to the fair value of the instruments. The Company actively monitors its exposure to credit risk through the use of credit approvals and credit limits, and by selecting major international banks and financial institutions as counterparties. The Company does not anticipate nonperformance by any of these counterparties. 3M has credit support agreements in place with two of its primary derivatives counterparties. Under these agreements, either party is required to post eligible collateral when the market value of transactions covered by the agreements exceeds specified thresholds, thus limiting credit exposure for both parties.

NOTE 11.  Fair Value Measurements

3M follows ASC 820, Fair Value Measurements and Disclosures, with respect to assets and liabilities that are measured at fair value on a recurring basis and nonrecurring basis. Under the standard, fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The standard also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The hierarchy is broken down into three levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

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, available-for-sale investments (included as part of investments in the Consolidated Balance Sheet) and certain derivative instruments. Derivatives include cash flow hedges, interest rate swaps and most net investment hedges. 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 the nine month periods ended September 30, 2010 and 2009.

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 auction rate securities:

Marketable securities, except auction rate 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 auction rate securities) are classified as level 2. Marketable securities are discussed further in Note 7.

Available-for-sale marketable securities — auction rate securities only:

As discussed in Note 7, auction rate securities held by 3M failed to auction since the second half of 2007. As a result, investments in auction rate securities are valued utilizing third-party indicative bid levels in markets that are not active and broker-dealer valuation models that utilize inputs such as current/forward interest rates, current market conditions and credit default swap spreads. 3M classifies these securities as level 3.

Available-for-sale investments:

Investments include equity securities that are traded in an active market. Closing stock prices are readily available from active markets and are used as being representative of fair value. 3M classifies these securities as level 1.

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, commodity price swaps, 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.

27

3M has determined that foreign currency forwards and commodity price swaps will be considered level 1 measurements as these are traded in active markets which have identical asset or liabilities, while currency swaps, foreign currency options, interest rate swaps and cross-currency swaps will be considered level 2. For level 2 derivatives, 3M uses inputs other than quoted prices that are observable for the asset. These inputs include foreign currency exchange rates, volatilities, and interest rates. The level 2 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 tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis.

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 11 in 3M’s Current Report on Form 8-K dated May 17, 2010.

Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis:

Disclosures are required for assets and liabilities that are measured at fair value, but are recognized and disclosed at fair value on a nonrecurring basis. During the nine months ended September 30, 2010 and 2009, such measurements of fair value related primarily to the identifiable assets and liabilities with respect to the business combinations that closed in 2010 and 2009 and long-lived asset impairments in 2009.

The following table provides information by level for assets and liabilities that were measured at fair value on a nonrecurring basis. This table provides the fair value of net identifiable tangible and intangible assets and liabilities (excluding goodwill) for business combinations that closed during the periods indicated. For business combinations, 3M uses inputs other than quoted prices that are observable, such as interest rates, cost of capital, and market comparable

29

royalty rates, which are applied to income and market valuation approaches. 3M considers these level 2 inputs. In addition, this table provides the fair value and amount of long-lived asset impairments for the periods indicated. The complete carrying amount of these assets were written off and included in operating income results. Asset impairments related to 2009 restructuring actions are discussed in Note 4. Refer to Note 1 (“Property, plant and equipment” and “Intangible Assets”) in 3M’s Current Report on Form 8-K dated May 17, 2010 for further discussion of accounting policies related to long-lived asset impairments.

There were no long-lived asset impairments for the three months or nine months ended September 30, 2010. There were no long-lived asset impairments for the three months ended September 30, 2009. Long-lived asset impairments for the nine months ended September 30, 2009, included the portion of 2009 restructuring actions related to long-lived asset impairments as discussed in Note 4, with the complete carrying amount of such assets written off and included in operating income results. In addition to the restructuring activities, in June 2009 the Company recorded a $13 million impairment of certain long-lived assets associated with the UK passport production activity of 3M’s Security Systems Division (within the Safety, Security and Protection Services business segment). In June 2009, 3M was notified that the UK government decided to award the production of its passports to a competitor upon the expiration of 3M’s existing UK passport contracts in October 2010. Accordingly, 3M tested the long lived assets associated with the UK passport activity for recoverability which indicated that the asset grouping’s carrying amount exceeded the remaining expected cash flows. As a result, associated assets were written down to a fair value of $41 million in June 2009. 3M primarily uses a discounted cash flow model that uses inputs other than quoted prices that are observable, such as interest rates and cost of capital, to determine the fair value of such assets. 3M considers these level 2 inputs.

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 and 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. Available-for-sale marketable securities and investments, in addition to certain derivative instruments, are recorded at fair values as indicated in the preceding disclosures. The Company utilized third-party quotes to estimate fair values for its long-term debt. Information with respect to the carrying amounts and estimated fair values of these financial instruments follow:

	September 30, 2010				December 31, 2009
(Millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term debt, excluding current portion	$	5,105	$	5,529	$	5,097	$	5,355

The fair values reflected 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 fixed rate Eurobond securities issued by the Company as hedging instruments of the Company’s net investment in its European subsidiaries. 3M’s fixed-rate bonds are trading at a premium at September 30, 2010 and December 31, 2009 due to the low interest rates and tightening of 3M’s credit spreads.

NOTE 12.  Commitments and Contingencies

Legal Proceedings:

The Company and some of its subsidiaries are involved in numerous claims and lawsuits, principally in the United States, and regulatory proceedings worldwide. These include various products liability (involving products that the Company now or formerly manufactured and sold), intellectual property, and commercial claims and lawsuits, including those brought under antitrust laws, and environmental proceedings. The following sections first describe the significant legal proceedings in which the Company is involved, and then describe the liabilities and associated insurance receivables the Company has accrued relating to its significant legal proceedings. Unless otherwise stated, the Company is vigorously defending all such litigation.  Additional information can be found in Note 14 “Commitments and Contingencies” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009, as updated by our Current Report on Form 8-K dated May 17, 2010, including information about the Company’s process for establishing and disclosing accruals and insurance receivables.

French Competition Authority Investigation

On December 4, 2008, the Company’s subsidiary in France received a Statement of Objections from the French Competition Authority alleging an abuse of a dominant position regarding the supply of retro-reflective films for vertical signing applications in France and participation in a concerted practice with the major French manufacturers of vertical signs. The Statement of Objections is an intermediate stage in the proceedings and no final determination regarding an infringement of French competition rules has been made. 3M has filed its response denying that the Statement of Objections states a valid claim against 3M. A hearing before a panel of the Competition Authority occurred in September 2010. The Competition Authority is expected to render its decision in the fourth quarter of 2010. It is difficult to predict the final outcome of the investigation at this time.

Compliance Matters

On November 12, 2009, the Company contacted the Department of Justice (DOJ) and Securities and Exchange Commission (SEC) to voluntarily disclose that the Company was conducting an internal investigation as a result of reports it received about its subsidiary in Turkey, alleging bid rigging and bribery and other inappropriate conduct in connection with the supply of certain reflective and other materials and related services to Turkish government entities. The Company also contacted certain affected government agencies in Turkey.  The Company continues to cooperate with the DOJ and SEC in the Company’s ongoing investigation of this matter.  The Company retained outside counsel to conduct an assessment of its policies, practices, and controls and to evaluate its overall compliance with the Foreign Corrupt Practices Act, including an ongoing review of our practices in certain other countries.  The Company cannot predict at this time the outcome of its investigation or what regulatory actions may be taken or what other consequences may result.

Employment Litigation

Whitaker lawsuit: As previously reported, in December, 2004, one current and one former employee of the Company filed a purported class action in the District Court of Ramsey County, Minnesota, seeking to represent a class of all current and

31

certain former salaried employees employed by the Company in Minnesota below a certain salary grade who were age 46 or older at any time during the applicable period to be determined by the Court (the “Whitaker” lawsuit). The complaint alleges the plaintiffs suffered various forms of employment discrimination on the basis of age in violation of the Minnesota Human Rights Act and seeks injunctive relief, unspecified compensatory damages (which they seek to treble under the statute), including back and front pay, punitive damages (limited by statute to $8,500 per claimant) and attorneys’ fees. In January 2006, the plaintiffs filed a motion to join four additional named plaintiffs. This motion was unopposed by the Company and the four plaintiffs were joined in the case, although one plaintiff’s claim was dismissed following an individual settlement. A class certification hearing was held in December 2007. On April 11, 2008, the Court granted the plaintiffs’ motion to certify the case as a class action and defined the class as all persons who were 46 or older when employed by 3M in Minnesota in a salaried exempt position below a certain salary grade at any time on or after May 10, 2003, and who did not sign a document on their last day of employment purporting to release claims arising out of their employment with 3M.  On April 28, 2009, the Minnesota Court of Appeals reversed the District Court’s class certification decision. The Court of Appeals found that the District Court had not required plaintiffs to meet the proper legal standards for certification of a class under Minnesota law and incorrectly had deferred resolving certain factual disputes that were relevant to the class certification requirements. The Court of Appeals remanded the case to the District Court for further proceedings in line with the evidentiary standards defined in its opinion. The trial court took expert testimony on the class certification issue on May 5-6, 2010 and held a hearing on the issue on August 25, 2010, and later this year will issue a new decision on whether the case should proceed as a class action.

Garcia lawsuit: The Company was served on May 7, 2009 with a purported class action/collective action age discrimination lawsuit, which was filed in United States District Court for the Northern District of California, San Jose Division (the “Garcia lawsuit”). The case has since been transferred to the U.S. District Court for the District of Minnesota.  The case is still in the initial phase of discovery.

In this case, five former and one current employee of the Company are seeking to represent all current and former salaried employees employed by the Company in the United States during the liability period, which plaintiffs define as 2001 to the present. In addition to the six named plaintiffs, there are presently 87 other current or former employees who have signed “opt-in” forms, seeking to join the action.  This number has changed since the case was filed and is likely to change again as the case progresses. The Garcia lawsuit expressly excludes those persons encompassed within the proposed class in the Whitaker lawsuit.  The same firm, joined by additional California counsel and local Minnesota counsel for the Garcia lawsuit, represents the plaintiffs in both cases.

The allegations of the complaint in the Garcia lawsuit are similar to those in the Whitaker lawsuit. Plaintiffs claim that they and other similarly situated employees suffered various forms of employment discrimination on the basis of age in violation of the federal Age Discrimination in Employment Act.  In regard to these claims, plaintiffs seek to represent “all persons who were 46 or older when employed by 3M in the United States in a salaried position below the level of director, or salary grade 18, during the liability period.”  Because federal law protects persons age 40 and older from age discrimination, with respect to their claim of disparate impact only, plaintiffs also propose an alternative definition of similarly situated persons that would begin at age 40.  On behalf of this group, plaintiffs seek injunctive relief, unspecified compensatory damages including back and front pay, benefits, liquidated damages and attorneys’ fees.

Certain of the plaintiffs’ and putative class members’ employment terminated under circumstances in which they were eligible for group severance plan benefits and in connection with those plans they signed waivers of claims, including age discrimination claims. Plaintiffs claim the waivers of age discrimination claims were invalid in various respects.  This subset of release-signing plaintiffs seeks a declaration that the waivers of age discrimination claims are invalid, other injunctive, but non-monetary, remedies, and attorneys’ fees.

EEOC age-discrimination charges: Six former employees and one current employee, all but one of whom are plaintiffs in the Garcia lawsuit, have also filed age discrimination charges against the Company with the U.S. Equal Employment Opportunity Commission and various pertinent state agencies, alleging age discrimination similar to the Whitaker and Garcia lawsuits and claiming that a class of similarly situated persons exists.  Of these, three former employees filed charges in 2005 in Minnesota, Texas, and California. These filings include allegations that the release of claims signed by certain former employees in the purported class defined in the charges is invalid for various reasons and assert age discrimination claims on behalf of certain current and former salaried employees in states other than Minnesota and New Jersey. In 2006, a current employee filed an age discrimination charge against the Company with the U.S. Equal Employment Opportunity Commission and the pertinent state agency in Missouri, asserting claims on behalf of a class of all current and certain former salaried employees who worked in Missouri and other states other than Minnesota and New Jersey. In 2007, a former employee filed an age discrimination charge against the Company with the U.S. Equal Employment Opportunity Commission and the pertinent state agency in California, asserting claims on behalf of a class of all current and certain former salaried employees who worked in California.  In January 2009, two former employees filed age discrimination charges against the Company with the U.S. Equal Employment Opportunity Commission and the pertinent state agency in Minnesota.  The filings include allegations that the release of claims signed by certain former employees in the purported class defined in the charges is invalid for various reasons and assert age discrimination claims on behalf of certain current and former salaried employees in states other than Minnesota. The same law firm represents the plaintiffs in the Whitaker lawsuit as well as the claimants in each of these EEOC proceedings.

Respirator Mask/Asbestos Litigation

As of September 30, 2010, the Company is a named defendant, with multiple co-defendants, in numerous lawsuits in various courts that purport to represent approximately 2,190 individual claimants, down from the approximately 2,510 individual claimants with actions pending at December 31, 2009.

The vast majority of the lawsuits and claims resolved by and currently pending against the Company allege use of some of the Company’s mask and respirator products and seek damages from the Company and other defendants for alleged personal injury from workplace exposures to asbestos, silica, coal mine dust or other occupational dusts found in products manufactured by other defendants or generally in the workplace. A minority of claimants generally allege personal injury from occupational exposure to asbestos from products previously manufactured by the Company, which are often unspecified, as well as products manufactured by other defendants, or occasionally at Company premises.

The Company’s current volume of new and pending matters is substantially lower than its historical experience. The Company expects that filing of claims by unimpaired claimants in the future will continue to be at much lower levels than in the past. Accordingly, the number of claims alleging more serious injuries, including mesothelioma and other malignancies, while remaining relatively constant and consistent with historical experience, will represent a greater percentage of total claims than in the past. The Company has demonstrated in past trial proceedings that its respiratory protection products are effective as claimed when used in the intended manner and in the intended circumstances. Consequently the Company believes that claimants are unable to establish that their medical conditions, even if significant, are attributable to the Company’s respiratory protection products. Nonetheless the Company’s litigation experience indicates that claims of persons with malignant conditions are costlier to resolve than the claims of unimpaired persons, and it therefore believes the average cost of resolving pending and future claims on a per-claim basis will continue to be higher than it experienced in prior periods when the vast majority of claims were asserted by the unimpaired.

Respirator Mask/Asbestos Litigation — Aearo Technologies

On April 1, 2008, a subsidiary of the Company purchased the stock of Aearo Holding Corp., the parent of Aearo Technologies (“Aearo”).  Aearo manufactures and sells various products, including personal protection equipment, such as eye, ear, head, face, fall and certain respiratory protection products.

As of September 30, 2010, Aearo and/or other companies that previously owned and operated Aearo’s respirator business (American Optical Corporation, Warner-Lambert LLC, AO Corp. and Cabot Corporation (“Cabot”)) are named defendants, with multiple co-defendants, sometimes including the Company, in numerous lawsuits in various courts in which plaintiffs allege use of mask and respirator products and seek damages from Aearo and other defendants for alleged personal injury from workplace exposures to asbestos, silica-related, or other occupational dusts found in products manufactured by other defendants or generally in the workplace.

As of September 30, 2010, the Company, through its Aearo subsidiary, has recorded $33 million as an estimate of the probable liabilities for product liabilities and defense costs related to current and future Aearo-related asbestos and silica-related claims. Responsibility for legal costs, as well as for settlements and judgments, is currently shared in an informal arrangement among Aearo, Cabot, American Optical Corporation and a subsidiary of Warner Lambert and their insurers (the “Payor Group”). Liability is allocated among the parties based on the number of years each company sold respiratory products under the “AO Safety” brand and/or owned the AO Safety Division of American Optical Corporation and the alleged years of exposure of the individual plaintiff.  Aearo’s share of the contingent liability is further limited by an agreement entered into between Aearo and Cabot on July 11, 1995. This agreement provides that, so long as Aearo pays to Cabot an annual fee of $400,000, Cabot will retain responsibility and liability for, and indemnify Aearo against, asbestos and silica-related product liability claims for respirators manufactured prior to July 11, 1995.  Because the date of manufacture for a particular respirator allegedly used in the past is often difficult to determine, Aearo and Cabot have applied the agreement to claims arising out of the alleged use of respirators while exposed to asbestos or silica or products containing asbestos or silica prior to January 1, 1997. With these arrangements in place, Aearo’s potential liability is limited to exposures alleged to have arisen from the use of respirators while exposed to asbestos, silica or other occupational dusts on or after January 1, 1997.

To date, Aearo has elected to pay the annual fee.  Aearo could potentially be exposed to additional claims for some part of the pre-July 11, 1995 period covered by its agreement with Cabot if Aearo elects to discontinue its participation in this arrangement, or if Cabot is no longer able to meet its obligations in these matters.

Developments may occur that could affect the estimate of Aearo’s liabilities. These developments include, but are not limited to: (i) significant changes in the number of future claims, (ii) significant changes in the average cost of resolving claims, (iii) significant changes in the legal costs of defending these claims, (iv) significant changes in the mix and nature of claims received, (v) trial and appellate outcomes, (vi) significant changes in the law and procedure applicable to these claims, (vii) significant changes in the liability allocation among the co-defendants, (viii) the financial viability of members of the Payor Group including exhaustion of available coverage limits, (ix) the outcome of pending insurance coverage litigation among certain other members of the Payor Group and their respective insurers, and/or (x) a determination that the interpretation of the contractual obligations on which Aearo has estimated its share of liability is inaccurate. The Company cannot determine the impact of these potential developments on its current estimate of Aearo’s share of liability

33

for these existing and future claims.  If any of the developments described above were to occur, the actual amount of these liabilities for existing and future claims could be significantly larger than the reserved amount.

Environmental Matters and Litigation

The Company’s operations are subject to environmental laws and regulations including those pertaining to air emissions, wastewater discharges, toxic substances, and the handling and disposal of solid and hazardous wastes enforceable by national, state, and local authorities around the world, and private parties in the United States and abroad. These laws and regulations provide, under certain circumstances, a basis for the remediation of contamination and for personal injury and property damage claims. The Company has incurred, and will continue to incur, costs and capital expenditures in complying with these laws and regulations, defending personal injury and property damage claims, and modifying its business operations in light of its environmental responsibilities. In its effort to satisfy its environmental responsibilities and comply with environmental laws and regulations, the Company has established, and periodically updates, policies relating to environmental standards of performance for its operations worldwide.

Remediation: Under certain environmental laws, including the United States Comprehensive Environmental Response, Compensation and Liability Act of 1980 and similar state laws, the Company may be jointly and severally liable, typically with other companies, for the costs of environmental contamination at current or former facilities and at off-site locations. The Company has identified numerous locations, most of which are in the United States, at which it may have some liability. Please refer to the “Environmental remediation liabilities” in the table in the following section, “Accrued Liabilities and Insurance Receivables Related to Legal Proceedings,” for information on the amount of the reserve.

Regulatory Activities: As previously reported, the Company has been voluntarily cooperating with ongoing reviews by local, state, national (primarily the U.S. Environmental Protection Agency (EPA)), and international agencies of possible environmental and health effects of various perfluorinated compounds (“PFCs”), including perfluorooctanyl compounds (perflurooctanoic acid or “PFOA” and perfluorooctane sulfonate or “PFOS”). As a result of its phase-out decision in May 2000, the Company no longer manufactures perfluorooctanyl compounds, and through changes to its manufacturing process at the end of 2008, no longer uses such compounds in its manufacturing process.

Regulatory activities concerning PFOA and/or PFOS continue in Europe and elsewhere, and before certain international bodies. These activities include gathering of exposure and use information, risk assessment, and consideration of regulatory approaches.

In late 2008 and early 2009, the EPA implemented testing of private wells and soils at certain agricultural sites in Alabama where wastewater treatment sludge was applied from a local wastewater treatment plant that received wastewater from numerous industrial sources.  In this same timeframe, the EPA also issued provisional health advisory values for PFOA of 0.4 ppb and PFOS of 0.2 ppb.  The EPA currently believes that these levels are protective of drinking water supplies for a lifetime of consumption and is working with local industry, including 3M, to continue testing municipal and private wells in the area.  EPA’s testing of public drinking water supplies in Lawrence and Morgan Counties indicate that the levels of PFOA and PFOS are well below the provisional health advisories. 3M and other companies have completed the survey of properties near the sites where wastewater treatment sludge was applied to determine if any further private drinking water wells are present and will continue to monitor for another quarter those few wells that showed levels of PFOS or PFOA above detection levels but below the EPA’s provisional health advisory levels.  If any private wells are found to exceed the EPA’s provisional health advisory levels, 3M and the other companies will provide alternative water supplies.

As previously reported, the Company entered into a voluntary remedial action agreement with the Alabama Department of Environmental Management (ADEM) to address the presence of PFCs in the soil on the Company’s manufacturing facility in Decatur, Alabama.  For approximately twenty years, the Company incorporated wastewater treatment plant sludge containing PFCs in fields surrounding its Decatur facility pursuant to a permit issued by ADEM.  After a review of the available options to address the presence of PFCs in the soil, ADEM agreed that the preferred remediation option is to use a multilayer cap over the former sludge incorporation areas on the manufacturing site with groundwater migration controls and treatment.

The Company continues to work with the Minnesota Pollution Control Agency (MPCA) pursuant to the terms of the previously disclosed May 2007 Settlement Agreement and Consent Order to address the presence of perfluorinated compounds in the soil and groundwater at former disposal sites in Washington County Minnesota and at the Company’s manufacturing facility at Cottage Grove Minnesota. Under this agreement, the Company’s principal obligations include (i) evaluating releases of perfluoronated compounds from these sites and proposing response actions; (ii) providing alternative drinking water if and when an Health Based Value (“HBV”) or Health Risk Limit (“HRL”) (i.e., the amount of a chemical in drinking water determined by the Minnesota Department of Health to be safe for people to drink for a lifetime) is exceeded for any perfluoronated compounds as a result of contamination from these sites; (iii) remediating any source of other PFCs at these sites that is not controlled by actions to remediate PFOA and PFOS; and (iv) sharing information with the MPCA about perfluoronated compounds. During 2008, the MPCA issued formal decisions adopting remedial options for the former disposal sites in Washington County Minnesota (Oakdale and Woodbury).  In August 2009, the MPCA issued a formal decision adopting remedial options for the Company’s Cottage Grove manufacturing facility.  At each location the remedial options were among those recommended by the Company. During the spring and summer of

34

2010, 3M began implementing the remedial options at the Cottage Grove and Woodbury sites.  3M expects to commence the remedial option at the Oakdale site later this year.  Remediation work will continue at all three sites into 2011.

Please refer to the “Other environmental liabilities” in the table in the following section, “Accrued Liabilities and Insurance Receivables Related to Legal Proceedings” for information on the balance of the reserve established to implement the Settlement Agreement and Consent Order with the MPCA, the remedial action agreement with ADEM, and to address trace amounts of perfluorinated compounds in drinking water sources in the Cities of Oakdale and Lake Elmo, Minnesota, as well as presence in the soil and groundwater at the Company’s manufacturing facilities in Decatur, Alabama, and Cottage Grove, Minnesota, and at two former disposal sites in Minnesota.

The Minnesota Pollution Control Agency and the Minnesota Department of Natural Resources, acting in their capacity as trustees (“Trustees”) of the natural resources of the State of Minnesota, have indicated an intent to commence a legal action against 3M to recover natural resource damages under the Minnesota Environmental Response and Liability Act (MERLA) with respect to the presence of PFC’s in the groundwater in Washington County, Minnesota and in the surface water of the Mississippi River in the area of the 3M Cottage Grove, Minnesota facility.  The parties have entered into an agreement tolling the statute of limitations on any such claim until the end of the year or upon termination by either party to allow for discussions to take place to determine if a resolution can be reached.  3M believes that MERLA does not define PFCs as a “hazardous substance” and, as a result, does not provide any basis for recovery of natural resource damages.

The Company cannot predict what regulatory actions arising from the foregoing proceedings and activities, if any, may be taken regarding such compounds or the consequences of any such actions.

In March 2010, the Wisconsin Department of Justice notified the Company that it is seeking $270,000 in penalties for alleged past violations of the Wisconsin Air Management regulations at the Company’s manufacturing facility in Prairie du Chien, Wisconsin.  In July 2010 the Company and the State of Wisconsin reached a settlement of the matter by the Company paying a $150,000 penalty and agreeing to implement two environmental projects at its manufacturing facility.

Litigation: As previously reported, a former employee filed a purported class action lawsuit in 2002 in the Circuit Court of Morgan County, Alabama, involving perfluorooctanyl chemistry, alleging that the plaintiffs suffered fear, increased risk, subclinical injuries, and property damage from exposure to perfluorooctanyl chemistry at or near the Company’s Decatur, Alabama, manufacturing facility. The Circuit Court in 2005 granted the Company’s motion to dismiss the named plaintiff’s personal injury-related claims on the basis that such claims are barred by the exclusivity provisions of the state’s Workers Compensation Act. The plaintiffs’ counsel filed an amended complaint in November 2006, limiting the case to property damage claims on behalf of a purported class of residents and property owners in the vicinity of the Decatur plant. Discovery on issues related to whether the case should proceed as a class action is underway.

Also in 2005, the judge in a second purported class action lawsuit (filed by three residents of Morgan County, Alabama, seeking unstated compensatory and punitive damages involving alleged damage to their property from emissions of perfluorooctanyl compounds from the Company’s Decatur, Alabama, manufacturing facility that formerly manufactured those compounds) granted the Company’s motion to abate the case, effectively putting the case on hold pending the resolution of class certification issues in the action described above filed in the same court in 2002. Despite the stay, plaintiffs filed an amended complaint seeking damages for alleged personal injuries and property damage on behalf of the named plaintiffs and the members of a purported class.  No further action in the case is expected unless and until the stay is lifted.

In February 2009, a resident of Franklin County, Alabama, filed a purported class action lawsuit in the Circuit Court of Franklin County seeking compensatory damages and injunctive relief based on the application by the Decatur wastewater treatment plant of wastewater treatment sludge to farmland and grasslands in the state that allegedly contain PFOA, PFOS and other perfluorochemicals. The named defendants in the case include 3M, Dyneon LLC, Daikin America, Inc., Synagro-WWT, Inc., Synagro South, LLC and Biological Processors of America.  The named plaintiff seeks to represent a class of all persons within the State of Alabama, Inc. who, within the past six years, have had PFOA, PFOS and other perfluorochemicals released or deposited on their property.  The defendants challenged venue in Franklin County, arguing that the plaintiff had no connections to that county and asking that it be transferred to Morgan County, where the other cases are filed.  The trial court found venue was proper in a different, adjoining county. Following a successful appeal to the Alabama Supreme Court, the case was transferred to Morgan County. Pursuant to a motion filed by the defendants, this case also has been abated, or stayed, pending the outcome in the first case filed in Morgan County, in 2002.  Again, no activity is expected in this case unless and until the stay is lifted.

In July 2009, the Emerald Coast Utilities Authority in Florida filed a lawsuit against the Company, E.I. DuPont de Nemours and Company, Solutia, Inc., and Fire Ram International, Inc. in the Escambia County Circuit Court alleging contamination of public drinking water wells from PFOA and PFOS and seeking to recover costs related to investigation, treatment, remediation and monitoring of alleged PFOA and PFOS contamination of its wells.  The Company, joined by the other defendants, removed the lawsuit to the U. S. District Court for the Northern District of Florida.  On November 19, 2009 the District Court denied the plaintiff’s motion to remand the case to state court, finding that plaintiff’s joinder of

35

the only Florida defendant, Fire Ram International, Inc., was fraudulent.  The District Court subsequently denied the plaintiff’s motion for leave to file an amended complaint on grounds of timeliness. On April 29, 2010, the Company and the other defendants argued motions for summary judgment, seeking dismissal of the case on various legal grounds.  On September 29, 2010, the Court granted these motions and dismissed the lawsuit with prejudice.

In June 2009, the Company, along with more than 250 other companies, was served with a third-party complaint seeking contribution towards the cost of cleaning up a 17-mile stretch of the Passaic River in New Jersey.  After commencing an enforcement action in 1990, the State of New Jersey filed suit against Maxus Energy, Tierra Solutions, Occidental Chemical and two other companies seeking cleanup and removal costs and other damages associated with the presence of dioxin and other hazardous substances in the sediment of the Passaic.  The third-party complaint seeks to spread those costs among the third-party defendants, including the Company.  Based on the cleanup remedy currently proposed by the EPA, the total costs at issue could easily exceed $1 billion.  The Company’s recent involvement in the case appears to relate to its past disposal of industrial waste at two commercial waste disposal facilities in New Jersey.  Whether, and to what extent, the Company may be required to contribute to the costs at issue in the case remains to be determined.  The Company does not yet have a basis for estimating its potential exposure in this case, although the Company currently believes its allocable share, if any, of the total costs is likely to be a fraction of one percent.

Accrued Liabilities and Insurance Receivables Related to Legal Proceedings

The following table shows the major categories of significant legal matters — respirator/mask/asbestos litigation (including Aearo), environmental remediation and other environmental liabilities — for which the Company has been able to estimate its probable liability and for which the Company has taken reserves and the related insurance receivables:

Liability and Receivable Balances	Sept. 30,		Dec. 31,
(Millions)	2010		2009
Respirator mask/asbestos liabilities	$	124	$	138
Respirator mask/asbestos insurance receivables	119		143
Environmental remediation liabilities	$	29	$	31
Environmental remediation insurance receivables	15		15
Other environmental liabilities	$	98	$	117

The Company does not believe that there is any single best estimate of the respirator/mask/asbestos liability, the environmental remediation or the other environmental liabilities shown above.  In addition to the major categories summarized in the table, the Company from time-to-time records reserves with respect to certain other claims or proceedings.  For legal matters for which the Company has recorded reserves, the Company cannot reliably estimate the amount or range of amounts by which those liabilities may exceed the reserves the Company has established. For those significant pending legal proceedings for which the Company has not accrued a reserve, the Company has determined that liability is not probable or the amount of the liability is not estimable, or both, and the Company is unable to estimate the possible loss or range of loss at this time.

As a result of the greater cost of resolving claims of persons with malignant conditions, as of September 30, 2010, the Company increased its reserves for respirator mask/asbestos liabilities by $5 million and increased its receivables for insurance recoveries by $1 million related to this litigation. As a result of settlements reached with its insurers (primarily in the first quarter of 2010), the Company was paid approximately $25 million for the first nine months of 2010 in connection with the respirator mask/asbestos receivable.

As previously reported, on January 5, 2007 the Company was served with a declaratory judgment action filed on behalf of two of its insurers (Continental Casualty and Continental Insurance Co. — both part of the Continental Casualty Group) disclaiming coverage for respirator mask/asbestos claims. These insurers represent approximately $14 million of the $119 million insurance recovery receivable referenced in the above table. The action, pending in the District Court in Ramsey County, Minnesota, seeks declaratory judgment regarding coverage provided by the policies and the allocation of covered costs among the policies issued by the various insurers. The action named, in addition to the Company, over 60 of the Company’s insurers. This action is similar in nature to an action filed in 1994 with respect to breast implant coverage, which ultimately resulted in the Minnesota Supreme Court’s ruling of 2003 that was largely in the Company’s favor.  The plaintiff insurers have served an amended complaint that names some additional insurers and deletes others.  Several of the insurer defendants named in the amended complaint have been dismissed because of settlements they have reached with 3M regarding the matters at issue in the lawsuit. Three additional insurers have recently been or are being added as parties to the case.  The case remains in its early stages with a trial scheduled to begin in June, 2012.

NOTE 13. Stock-Based Compensation

In May 2008, shareholders approved 35 million shares for issuance under the “3M 2008 Long-Term Incentive Plan”, which replaced and succeeded the 2005 Management Stock Ownership Program (MSOP), the 3M Performance Unit Plan, and the 1992 Directors Stock Ownership Program. In May 2010, shareholders approved an additional 29 million shares for issuance under the 2008 Plan, increasing the number of approved shares from 35 million to 64 million shares. Shares under this plan may be issued in the form of Incentive Stock Options, Nonqualified Stock Options, Progressive Stock Options, Stock Appreciation Rights, Restricted Stock, Restricted Stock Units, Other Stock Awards, and Performance Units and Performance Shares. Awards denominated in shares of common stock other than options and Stock Appreciation Rights, per the 2008 Plan, count against the 64 million share limit as 3.38 shares for every one share covered by such award (for full value awards with grant dates prior to May 11, 2010), or as 2.87 shares for every one share covered by such award (for full value awards with grant dates of May 11, 2010, or later). The remaining total shares available for grant under the 2008 Long Term Incentive Plan Program are 32,083,364 as of September 30, 2010.

In 2009, the Company changed the timing of its annual stock option and restricted stock unit grant dates from May to February, in order to provide a stronger and more immediate link between the performance of individuals during the preceding year and the size of their annual stock option grants. In 2008 and prior, the Company issued options to eligible employees annually in May using the closing stock price on the grant date, which was the date of the Annual Stockholders’ Meeting. Accounting rules require recognition of expense under a non-substantive vesting period approach, requiring compensation expense recognition when an employee is eligible to retire. 3M employees in the United States are eligible to retire at age 55 and after having completed five years of service. Stock-based compensation award expense for this retiree-eligible population has ranged from 25 to 30 percent of the total annual grant stock-based compensation award expense.

The income tax benefits shown in the following table can fluctuate by period due to the amount of Incentive Stock Options (ISOs) exercised since the Company receives the ISOs tax benefit upon exercise. The Company last granted ISOs in 2002. Amounts recognized in the financial statements with respect to stock-based compensation programs, which include stock options, restricted stock, restricted stock units and the General Employees’ Stock Purchase Plan (GESPP), are as follows:

	Three months ended						Nine months ended
	September 30,						September 30,
(Millions)	2010			2009			2010			2009
Cost of sales	$	6		$	8		$	26		$	32
Selling, general and administrative expenses	45			29			174			115
Research, development and related expenses	6			7			28			29

*Weighted average

37

As of September 30, 2010, there was $81 million of compensation expense that has yet to be recognized related to non-vested stock option based awards. This expense is expected to be recognized over the remaining vesting period with a weighted-average life of 1.8 years. The total intrinsic values of stock options exercised was $214 million and $52 million during the nine-month periods ended September 30, 2010 and 2009, respectively. Cash received from options exercised was $433 million and $226 million for the nine months ended September 30, 2010 and 2009, respectively. The Company’s actual tax benefits realized for the tax deductions related to the exercise of employee stock options were $63 million and $16 million for the nine months ended September 30, 2010 and 2009, respectively. Capitalized stock-based compensation amounts were not material at September 30, 2010.

For the 2010 annual stock option grant, the weighted average fair value at the date of grant was calculated using the Black-Scholes option-pricing model and the assumptions that follow.

	Annual
Stock Option Assumptions	2010
Exercise price	$	78.72
Risk-free interest rate	2.8		%
Dividend yield	2.5		%
Expected volatility	25.7		%
Expected life (months)	72
Black-Scholes fair value	$	16.50

Expected volatility is a statistical measure of the amount by which a stock price is expected to fluctuate during a period. For the 2010 annual grant date, the Company estimated the expected volatility based upon the average of the most recent one year volatility, the median of the term of the expected life rolling volatility, the most recent term of the expected life volatility of 3M stock, and the implied volatility on the grant date. The expected term assumption is based on the weighted average of historical grants.

Restricted stock unit grants generally vest at the end of three years. The one-time “buyout” restricted stock unit grant in 2007 vests at the end of five years. The following table summarizes restricted stock and restricted stock unit activity during the nine months ended September 30, 2010:

Restricted Stock and Restricted Stock Units	Number of Awards		Grant Date Fair Value*
Nonvested balance —
As of January 1	4,379,480		$	68.85
Granted
Annual	902,550		78.81
Performance shares	686,322		73.98
Other	516,515		79.45
Vested	(796,943	)	79.40
Forfeited	(42,877	)	69.57
As of September 30	5,645,047		$	70.54

*Weighted average

As of September 30, 2010, there was $126 million of compensation expense that has yet to be recognized related to non-vested restricted stock and restricted stock units. This expense is expected to be recognized over the remaining vesting period with a weighted-average life of 1.8 years. The total fair value of restricted stock and restricted stock units that vested during the nine month period ended September 30, 2010 was $60 million and for the nine month period ended September 30, 2009 was $4 million. The Company’s actual tax benefits realized for the tax deductions related to the vesting of restricted stock and restricted stock units were $20 million for the nine months ended September 30, 2010 and were not material for the nine months ended September 30, 2009.

Restricted stock units granted under the “3M 2008 Long-Term Incentive Plan” generally vest three years following the grant date assuming continued employment. Beginning in 2009, dividend equivalents equal to the dividends payable on the same number of shares of 3M common stock accrue on these restricted stock units during the vesting period, although no dividend equivalents are paid on any of these restricted stock units that are forfeited prior to the vesting date. Since the rights to dividends are forfeitable, there is no impact on basic earnings per share calculations. Weighted average restricted stock unit shares outstanding are included in the computation of diluted earnings per share.

In addition, the Company issues cash settled Restricted Stock Units and Stock Appreciation Rights in certain countries. These grants do not result in the issuance of Common Stock and are considered immaterial by the Company.

NOTE 14. Business Segments

Effective in the first quarter of 2010, 3M made certain product moves between its business segments in its continuing effort to drive growth by aligning businesses around markets and customers. There were no changes impacting business segments related to product moves for the Health Care segment, Consumer and Office segment, Display and Graphics segment, or Electro and Communications segment. The product moves between business segments are summarized as follows:

·Certain acoustic systems products in the Occupational Health and Environmental Safety Division (part of the Safety, Security and Protection Services business segment) were transferred to the Automotive Division within the Industrial and Transportation business segment. In addition, thermal acoustics systems products which were included in the Occupational Health and Environmental Safety Division as a result of 3M’s April 2008 acquisition of Aearo Holding Corp. were transferred to the Aerospace and Aircraft Maintenance Department within the Industrial and Transportation business segment. These product moves establish an acoustic center of excellence within the Industrial and Transportation business segment. The preceding product moves resulted in an increase in net sales for total year 2009 of $116 million for Industrial and Transportation, which was offset by a corresponding decrease in net sales for Safety, Security and Protection Services.

3M’s businesses are organized, managed and internally grouped into segments based on differences in products, technologies and services. 3M continues to manage its operations in six operating business segments: Industrial and Transportation; Health Care; Consumer and Office; Display and Graphics; Safety, Security and Protection Services; and Electro and Communications. 3M’s six business segments bring together common or related 3M technologies, enhancing the development of innovative products and services and providing for efficient sharing of business resources. These segments have worldwide responsibility for virtually all 3M product lines. 3M is not dependent on any single product/service or market. Transactions among reportable segments are recorded at cost. 3M is an integrated enterprise characterized by substantial intersegment cooperation, cost allocations and inventory transfers. Therefore, management does not represent that these segments, if operated independently, would report the operating income information shown. The difference between operating income and pre-tax income relates to interest income and interest expense, which are not allocated to business segments.

The financial information presented herein reflects the impact of all of the preceding segment structure changes for all periods presented.

For the three months and nine months ended September 30, 2009, results included pre-tax charges of $26 million and $209 million, respectively, related to restructuring actions. Refer to Note 4 (Restructuring Actions and Exit Activities) for more detail. In addition, results for the nine months ended September 30, 2009 also included a gain on sale of real estate of $15 million pre-tax related to the sale of a New Jersey roofing granule facility (recorded within Safety, Security and Protection Services).

Corporate and unallocated operating income includes a variety of miscellaneous items, such as corporate investment gains and losses, certain derivative gains and losses, 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.

3M business segment reporting measures include dual credit to business segments for certain U.S. sales and related operating income. Management evaluates each of its six operating business segments based on net sales and operating income performance, including dual credit U.S. reporting to further incentivize U.S. sales growth. As a result, 3M provides additional (“dual”) credit to those business segments selling products in the U.S. to an external customer when that segment is not the primary seller of the product. For example, certain respirators are primarily sold by the Occupational Health and Environmental Safety Division within the Safety, Security and Protection Services business segment; however, the Industrial and Transportation business segment also sells this product to certain customers in its U.S. markets. In this example, the non-primary selling segment (Industrial and Transportation) would also receive credit for the associated net sales it initiated and the related approximate operating income. The assigned operating income related to dual credit activity may differ from operating income that would result from actual costs associated with such sales. The offset to the dual credit business segment reporting is reflected as a reconciling item entitled “Elimination of Dual Credit,” such that sales and operating income for the U.S. in total are unchanged.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM*

To the Stockholders and Board of Directors of 3M Company:

We have reviewed the accompanying consolidated balance sheet of 3M Company and its subsidiaries as of September 30, 2010, and the related consolidated statements of income for the three-month and nine-month periods ended September 30, 2010 and 2009 and the consolidated statement of cash flows for the nine-month periods ended September 30, 2010 and 2009. These interim financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2009, and the related consolidated statements of income, of changes in stockholders’ equity and comprehensive income, and of cash flows for the year then ended (not presented herein), and in our report dated February 16, 2010, except with respect to our opinion on the consolidated financial statements insofar as it relates to the effects of the segment realignments discussed in Notes 3 and 17 as to which the date is May 17, 2010, we expressed an unqualified opinion on those consolidated financial statements.  In our opinion, the information set forth in the accompanying consolidated balance sheet information as of December 31, 2009, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is designed to provide a reader of 3M’s financial statements with a narrative from the perspective of management. 3M’s MD&A is presented in the following sections:

·Overview

·Results of Operations

·Performance by Business Segment

·Financial Condition and Liquidity

·Forward-Looking Statements

OVERVIEW

3M is a diversified global manufacturer, technology innovator and marketer of a wide variety of products and services. 3M manages its operations in six operating business segments: Industrial and Transportation; Health Care; Consumer and Office; Display and Graphics; Safety, Security and Protection Services; and Electro and Communications. As discussed in Note 14 to the Consolidated Financial Statements, effective in the first quarter of 2010, 3M made certain product moves between its business segments. The financial information presented herein reflects the impact of these business segment changes for all periods presented.

Third-quarter 2010 sales increased 11.0 percent to $6.9 billion, driven by organic volume growth of 10.8 percent. This was the fourth consecutive quarter where year-on-year total sales growth exceeded 10 percent.  Acquisition benefits of 0.5 percent were partially offset by selling price declines of 0.2 percent and divestiture impacts of 0.1 percent. Year-on-year changes in foreign exchange rates had no impact on third quarter worldwide sales. Third-quarter sales growth was broad-based, with local-currency year-on-year increases of 24 percent in Electro and Communications, 18 percent in Display and Graphics, 14 percent in Industrial and Transportation, 11 percent in Consumer and Office and 2 percent in Health Care. In the Safety, Security and Protection Services business, local currency sales declined 2 percent versus the third quarter of 2009.

On a geographic basis, third-quarter 2010 sales rose 28 percent in Asia Pacific, 14 percent in Latin America/Canada and 6 percent in the United States. In Europe, organic sales volumes rose 4 percent, but sales in total declined 1 percent as currency effects more than offset volume gains. Sales to emerging markets grew by 25 percent in the third quarter, including increases of 48 percent in Korea, 39 percent in India, 32 percent in Russia, 31 percent in the China/Hong Kong region and 25 percent in Brazil.

Sales in the first nine months of 2010 increased 17.4 percent to $20.0 billion, driven primarily by a 16 percent increase in organic volumes. All business segments and major geographic areas showed improvement. Sales growth was strongest in emerging economies, led by developing Asia. Sales globally were helped by improved market penetration and new product flow along with significant growth in important end-markets such as electronics, automotive OEM and the core industrial market. In addition, 3M continues to invest in high-growth programs and to drive growth in adjacent market spaces. These efforts, combined with an improving economic backdrop, helped drive sales and income growth in the first nine months of the year.

The first quarter of 2010 includes a one-time, non-cash income tax charge of $84 million, or 11 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 in the aggregate resulting in a reduction of approximately 6,400 positions. These actions resulted in 2009 total year savings of almost $400 million, with estimated additional incremental savings of more than $150 million in 2010, with the majority of this benefit in the first half of 2010. 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 expected in 2010. 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, of which $45 million, or $0.07 per diluted share, was recorded in the first quarter of 2009; $60 million, or $0.08 per diluted share, was recorded in the second quarter of 2009; and $14 million, or $0.02 per diluted share was recorded in the third quarter of 2009. Refer to the special items discussion at the end of this overview section for more detail.

Net income attributable to 3M in the third quarter of 2010 was $1.106 billion, or $1.53 per diluted shares. Including the preceding special items, this compares to $957 million, or $1.35 per diluted share, in the third quarter of 2009.

42

Including the preceding special items, net income attributable to 3M in the first nine months of 2010 was $3.157 billion, or $4.36 per diluted share, compared to $2.258 billion or $3.21 per diluted share, in the first nine months of 2009.

In the third quarter of 2010, four of 3M’s six business segments posted sales increases in excess of 10 percent. Operating income margins exceeded 20 percent in all six of the Company’s business segments. The following table contains sales and operating income results by business segment for the three months ended September 30, 2010 and 2009.

Sales in the third quarter of 2010 increased 11.0 percent. Sales growth was led by Electro and Communications at 25 percent, Display and Graphics at 19 percent, and Industrial and Transportation at 14 percent. Sales growth in these business segments was led by those businesses that serve electronics and automotive OEM, as well as businesses serving the broad industrial manufacturing sector. Local-currency sales (which includes volume, selling price and acquisition impacts, but excludes divestiture and translation impacts) increased 11.1 percent. Foreign currency and divestiture impacts were minimal. Operating income margins for the three months ended September 30, 2010 were 22.9 percent, compared to 23.9 percent in the third quarter of 2009. Refer to the section entitled “Performance by Business Segment” later in MD&A for a more detailed discussion of the results of the respective segments. Refer to Note 14 for discussion of Corporate and Unallocated and Elimination of Dual Credit.

3M generated $3.543 billion of operating cash flows for the nine months ended September 30, 2010, compared to $3.897 billion for the nine months ended September 30, 2009. Refer to the section entitled “Cash Flows from Operating Activities” later in the MD&A for a discussion of items impacting cash flows. 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 until the remaining amount is fully utilized. 3M stock repurchases from its Board authorization totaled $370 million for the first nine months of 2010, with the majority of these purchases in the second quarter of 2010. As of September 30, 2010, approximately $2.2 billion remained available for future purchases. In February 2010, 3M’s Board of Directors authorized a dividend increase of 2.9 percent for 2010, marking the 52nd consecutive year of dividend increases for 3M. 3M’s debt to total capital ratio (total capital defined as debt plus equity) at September 30, 2010 was 27 percent, compared to 30 percent at December 31, 2009. 3M 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. In addition to cash on hand, the Company has sufficient access to capital markets to meet currently anticipated growth and acquisition investment funding needs.

As discussed in Note 2, in October 2010, the Company purchased Arizant Inc., Attenti Holdings S.A. and a controlling interest in Cogent Inc. In Health Care, Arizant bolsters 3M’s infection prevention business, with its line of patient and body fluid warming systems designed to prevent hypothermia in surgical patients. Attenti Holdings, part of Safety, Security and Protection Services, is a supplier of remote personal electronic monitoring solutions for the law enforcement and eldercare industries. Cogent Inc., also part of Safety, Security and Protection Services, is a leader in finger, palm, face and iris-based biometric security technology. While these three acquisitions on a combined basis are expected to dilute fourth-quarter 2010 earnings by approximately 6 cents per diluted share, each has significant long-term growth potential.

In the fourth quarter of 2010, 3M expects to continue to generate solid organic sales volume growth in excess of economic growth, even as year-on-year sales growth comparisons become more difficult due to improving global economic conditions in the second half of 2009. 3M is providing a preview of its 2011 outlook below, but will address this outlook in more detail at a future date. Looking forward into 2011, 3M is currently targeting 2011 total sales growth of 11 percent, assuming September 30, 2010 exchange rates and a couple of percentage points from acquisitions. 3M expects to continue to generate organic sales volume growth in excess of

43

economic growth and is driving the business to deliver 35 percent incremental operating income margins on this organic sales growth. In addition, currency should be an additional income benefit, again reflecting current exchange rates.

There are a few major items that will negatively impact earnings in 2011. 3M expects that pension and postretirement expense will decrease 2011 earnings, when compared to 2010, by approximately 30 cents per diluted share. For the U.S. qualified pension plan, this estimate is based on discount rates as of September 30, 2010 and assumes that September-to-date 2010 asset return performance levels hold. This estimate also assumes that 3M makes an additional discretionary contribution of $700 million in cash to its pension plans in either the fourth quarter of 2010 or first quarter of 2011. However, the actual contribution may differ. If rates of return or discount rates become more favorable, 3M would likely contribute much less than this amount. The Company does not have a required minimum pension contribution obligation for its U.S. plans in 2010. This anticipated increase in 2011 pension and postretirement expense is primarily due to two factors. The first factor is the amortization of prior period investment losses. The second factor is the low level of interest rates, which are used to determine the discount rate. Lower discount rates increase the present value of assumed liabilities, which in turn increase future pension and postretirement expense.

3M also anticipates an 8 cent per diluted share penalty in 2011 due to a compensation policy change.  Prior to 2009, 3M allowed employees to bank a certain amount of unused vacation. Effective January 1, 2009, 3M employees were given two years to use their previously banked vacation, with the resulting reduction in 3M’s liability benefiting both 2009 and 2010 operating results. This change resulted in an estimated 8 cent per diluted share benefit in 2010 results, which will not carry-over into 2011, and thus, will negatively impact 2011 versus 2010 comparisons.  Finally, 3M’s early assessment of the income tax rate indicates an expected 2011 effective tax rate of 30 percent or slightly below compared to an estimated tax rate of 28.5 percent or less for 2010.

Any forward-looking statements contained in Part I, Item 2 involve risks and uncertainties that could cause results to differ materially from those projected (refer to the forward-looking statements section at the end of Part I, Item 2 and the risk factors provided in Part II, Item 1A for discussion of these risks and uncertainties).

2010 special items:

The first quarter of 2010 includes a one-time, non-cash income tax charge of $84 million, or 11 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 6 (Income Taxes).

2009 special items:

During the first nine months of 2009, management approved and committed to undertake certain restructuring actions, which resulted in a pre-tax charge of $26 million ($14 million reduction in net income attributable to 3M, or $0.02 per diluted share) for the three-months ended September 30, 2009, and $209 million pre-tax ($128 million reduction in net income attributable to 3M, or $0.18 per diluted share) for the nine-months ended September 30, 2009. This charge related to employee-related liabilities for severance/benefits and other of approximately $26 million pre-tax for the three-months ended September 30, 2009. Employee-related liabilities for severance/benefits and other of approximately $190 million pre-tax and fixed asset impairments of approximately $19 million pre-tax were recorded for the nine-months ended September 30, 2009. All business segments were impacted by these actions. For the three-months ended September 30, 2009, these charges were recorded in cost of sales; and research, development and related expenses, with these expenses totaling $25 million pre-tax and $1 million pre-tax, respectively. For the nine-months ended September 30, 2009, these charges were recorded in cost of sales; selling, general and administrative expenses; and research, development and related expenses, with these expenses totaling $110 million pre-tax, $91 million pre-tax and $8 million pre-tax, respectively. These items are discussed in more detail in Note 4 (Restructuring Actions and Exit Activities).

In June 2009, 3M completed the sale of a New Jersey roofing granule facility and recorded a pre-tax gain of $15 million ($9 million benefit to net income attributable to 3M, or $0.01 per diluted share). This gain was recorded in cost of sales within the Safety, Security and Protection Services business segment.

Sales in the third quarter of 2010 increased 11.0 percent, with broad-based geographic area growth led by Asia Pacific and Latin America/Canada. Selling prices decreased 0.2 percent in the third quarter. Acquisitions added 0.5 percent to growth, with the largest being the April 2010 acquisition of the A-One branded label business and related operations within 3M’s Consumer and Office business segment. Foreign currency impacts had no impact on worldwide third-quarter sales growth, as a positive foreign currency impact of 4.7 percent in Asia Pacific was offset by a negative impact of 5.1 percent in Europe.

Geographically, local-currency sales improved 22.9 percent in Asia Pacific, 13.5 percent in Latin America/Canada, 6.0 percent in the United States, and 4.2 percent in Europe. 3M experienced strong sales growth in electronics, automotive OEM and the broad industrial market. Selling prices declined by 1.4 percent in Asia Pacific, which was largely due to normal price-down trends within 3M’s electronic-related businesses.

Worldwide sales in the first nine months of 2010 increased 17.4 percent, driven by organic volume growth of 15.7 percent. Worldwide local-currency sales were led by Electro and Communications, Display and Graphics, and Industrial and Transportation. These three businesses have launched new products and increased sales in a number of important and growing industries, including consumer electronics, automotive OEM, general industrial and renewable energy. Geographically, local-currency sales increased 34.2 percent in Asia Pacific, 15.6 percent in Latin America/Canada, 8.9 percent in the United States and 8.0 percent in Europe.

Cost of sales includes manufacturing, engineering and freight costs. Cost of sales, measured as a percent of net sales, was 52.1 percent in the third quarter of 2010, an increase of 0.9 percentage points from the same quarter last year. A number of positive factors impacted year-on-year results. These factors included 10.8 percent growth in organic sales volume, along with cost savings related to prior years’ restructuring actions. In addition, as discussed in Note 4 (Restructuring Actions and Exit Activities), in the third quarter of 2009, 3M recorded $26 million in restructuring charges, of which $25 million was recorded in cost of sales. This expense of $25 million negatively impacted third-quarter 2009 cost of sales (as a percent of net sales) by 0.4 percentage points. These year-on-year benefits were offset by pricing impacts, both in terms of selling prices, which declined 0.2 percent, and raw materials, which increased approximately 2.5 percent year-on-year on a gross basis. In addition, sales mix had a negative impact. Items contributing to this sales mix penalty included a lower sales contribution from Health Care, which, as a percent of sales, has lower cost of sales than 3M on average. In addition, lower year-on-year H1N1-related respirator volume negatively impacted cost of sales. 3M experienced strong demand for these products in the third quarter of 2009, with respiratory factories running at capacity, which resulted in a lower cost of sales (as a percent of net sales) in the third quarter of 2009. These same factories ran at more normal levels in the third quarter of 2010.

Cost of sales in the first nine months of 2010, measured as a percent of net sales, decreased 1.0 percentage point, helped by growth in organic sales volume, improved factory utilization levels, along with cost savings related to prior years’ restructuring actions. In addition, the first nine months of 2009 included a penalty of 0.6 percentage points (as a percent of net sales) related to special items. As discussed in Note 4 (Restructuring Actions and Exit Activities), in the first nine months of 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 benefits were partially offset by pricing impacts, as selling prices declined 0.2 percent year-on-year, and raw material prices increased approximately 2 percent year-on-year on a gross basis.

Selling, general and administrative (SG&A) expenses increased 13 percent in the third quarter and 11 percent in the first nine months. In the third quarter and first nine months of 2010, sales and marketing expenses increased 18 percent and 14 percent, respectively, which included advertising and promotion investment increases of over 30 percent in the third quarter and approximately 29 percent for the first nine months. These increased investments in advertising and promotion are expected to help drive sales volumes, both now and into the future. In addition, 3M has increased both sales coverage and its marketing strength, particularly in faster-growing emerging economies. For the first nine months of 2010, general and administrative costs remained under control, as these costs increased only 5 percent compared to sales growth of 17 percent. SG&A expenses, measured as a percent of net sales, increased 0.3 percentage points in the third quarter and decreased 1.2 percentage points in the first nine months compared to the same periods in 2009. As indicated in Note 4, restructuring expenses of $91 million were recorded in SG&A expenses in the first nine months of 2009. Measured as a percent of sales, these restructuring expenses increased the first nine months of 2009 SG&A expenses by 0.5 percentage points.

Research, development and related (R&D) expenses increased 6 percent in the third quarter and increased 8 percent in the first nine months, as 3M has continued to support its key growth initiatives. R&D expenses, measured as a percent of net sales, totaled 5.2 percent, a decrease of 0.2 percentage points from the same quarter last year, but in dollars increased $19 million compared to the third quarter last year. As indicated in Note 4, $1 million in restructuring expenses was recorded in R&D expenses in the third quarter of 2009 and $8 million was recorded in the first nine months of 2009.

Operating Income:

3M uses operating income as one of its primary business segment performance measurement tools. Operating income margins were 23.1 percent of sales in the first nine months of 2010 compared to 20.4 percent of sales in the first nine months of 2009. For the first three quarters of 2010, all six business segments reported operating income margins of

46

greater than 20 percent. In the first nine months of 2009, restructuring charges, partially offset by the gain on sale of real estate, negatively impacted operating income by $194 million and reduced operating income margins by 1.2 percentage points.

Interest Expense and Income:

	Three months ended						Nine months ended
	September 30,						September 30,
(Millions)	2010			2009			2010			2009
Interest expense	$	51		$	55		$	151		$	165
Interest income	(11		)	(8		)	(27		)	(26		)
Total	$	40		$	47		$	124		$	139

Interest expense was lower for the first three months and nine months of 2010 when compared to the same periods last year, primarily due to reductions in U.S. long-term average debt balances and lower rates on floating rate debt. Interest income increased slightly in the third quarter of 2010, helped by higher cash and marketable securities balances, partially offset by lower yields on investments.

Provision for Income Taxes:

	Three months ended				Nine months ended
	September 30,				September 30,
(Percent of pre-tax income)	2010		2009		2010		2009
Effective tax rate	26.8	%	32.2	%	28.3	%	31.2	%

The effective tax rate for the third quarter of 2010 was 26.8 percent, compared to 32.2 percent during the third quarter of 2009, a decrease of 5.4 percent. The effective tax rate for the first nine months of 2010 was 28.3 percent, a decrease of 2.9 percent when compared to the same period in 2009. The most significant item that decreased the effective tax rate in both the third quarter and first nine months of 2010 related to international taxes, due primarily to the 2010 tax benefits resulting from the corporate alignment transactions that allowed the Company to increase its ownership of a foreign subsidiary. The transactions are described in the section of Note 5 entitled “Purchase of Subsidiary Shares and Transfers of Ownership Interest Involving Non-Wholly Owned Subsidiaries.”

The year-to-date effective tax rate for 2010 also includes a one-time income tax charge of $84 million as 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, which increased the year-to-date 2010 effective tax rate by 1.8 percent.

Certain other items impacted both third-quarter and first nine-month 2010 effective tax rates. Adjustments to income tax reserves benefited year-on-year effective tax rates. In addition, valuation allowances recorded against certain international deferred tax assets resulting from taxable losses, and the lapse of the research and development credit negatively impacted 2010 effective tax rates. Refer to Note 6 for further discussion of income taxes.

The company currently expects that its effective tax rate for total year 2010 will be 28.5 percent or less. 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.

Net Income Attributable to Noncontrolling Interest:

	Three months ended				Nine months ended
	September 30,				September 30,
(Millions)	2010		2009		2010		2009
Noncontrolling Interest	$	19	$	14	$	63	$	35

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 increase in net income attributable to noncontrolling interest primarily related to higher net income for Sumitomo 3M Limited, which is 3M’s most significant consolidated entity with non-3M ownership interests (3M owns 75 percent of Sumitomo 3M Limited as of September 30, 2010).

Currency Effects:

3M estimates that year-on-year currency effects, including hedging impacts, decreased net income attributable to 3M by approximately $15 million for the three months ended September 30, 2010 and increased net income attributable to 3M by approximately $15 million for the nine months ended September 30, 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

47

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. 3M estimates that year-on-year derivative and other transaction gains and losses decreased net income attributable to 3M by approximately $30 million for the three months ended September 30, 2010 and decreased net income attributable to 3M by approximately $110 million for the nine months ended September 30, 2010.

Significant Accounting Policies:

Information regarding new accounting pronouncements is included in Note 1 to the Consolidated Financial Statements.

3M generally considers local currencies as the functional currencies outside the United States. However, under Accounting Standards Codification (ASC) 830, Foreign Currency Matters, the reporting currency of a foreign entity’s parent is assumed to be that entity’s functional currency when the economic environment of a foreign entity is highly inflationary—generally when its cumulative inflation is approximately 100 percent or more for the three years that precede the beginning of a reporting period. 3M has a subsidiary in Venezuela with operating income representing less than 1.0 percent of 3M’s consolidated operating income for both 2009 and the nine-month period ended September 30, 2010. As previously disclosed by the Company in Note 1 to the consolidated financial statements in 3M’s Current Report on Form 8-K dated May 17, 2010, 3M determined that the cumulative inflation rate of Venezuela in November 2009 exceeded 100 percent. Accordingly, the financial statements of the Venezuelan subsidiary were remeasured as if its functional currency were that of its parent beginning January 1, 2010.

Regulations in Venezuela require the purchase and sale of foreign currency to be made at official rates of exchange that are fixed from time to time by the Venezuelan government. Certain laws in the country, however, provided an exemption for the purchase and sale of certain securities and resulted in an indirect “parallel” market through which companies obtained foreign currency without having to purchase it from Venezuela’s Commission for the Administration of Foreign Exchange (CADIVI). In May 2010, the Venezuelan government took control of the previously freely-traded parallel market. The government-controlled rate that emerged under the new Transaction system for Foreign Currency Denominated Securities (SITME) is not as unfavorable as the previous parallel rate in comparison to the official rates. As previously disclosed, as of December 31, 2009 (prior to the change in functional currency of 3M’s Venezuelan subsidiary in January 2010), 3M changed to use of the parallel exchange rate for translation of the financial statements of its Venezuelan subsidiary. Beginning January 1, 2010, as discussed above, the financial statements of the Venezuelan subsidiary are remeasured as if its functional currency were that of its parent. This remeasurement utilized the parallel rate through May 2010 and the SITME rate thereafter.

The Company continues to monitor circumstances relative to its Venezuelan subsidiary. Other factors notwithstanding, the change in functional currency of this subsidiary and associated remeasurement beginning January 1, 2010 as a result of Venezuela’s economic environment would decrease net sales of the Venezuelan subsidiary by approximately two-thirds in 2010 in comparison to 2009 (based on exchange rates at 2009 year-end), but will not otherwise have a material impact on operating income and 3M’s consolidated results of operations.

PERFORMANCE BY BUSINESS SEGMENT

As discussed in Note 14 to the Consolidated Financial Statements, effective in the first quarter of 2010, 3M made certain product moves between its business segments. Segment information for all periods presented has been reclassified to reflect the new segment structure.

Information related to 3M’s business segments for the third quarter and first nine months of both 2010 and 2009 is presented in the tables that follow. Organic local-currency sales include both organic volume impacts plus selling price impacts. Acquisition impacts, a component of local currency sales growth, are measured separately for the first twelve months of the acquisition. The divestiture impact, if any, translation impact and total sales change are also provided for each business segment.

Percent of sales	20.2		%	20.2		%	21.4		%	16.1		%

The Industrial and Transportation segment serves a broad range of markets, such as appliance, paper and packaging, food and beverage, electronics, automotive original equipment manufacturer (OEM) and automotive aftermarket (auto body shops and retail). 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.

Third quarter of 2010:

In the third quarter of 2010, sales in Industrial and Transportation increased 14.2 percent to $2.2 billion, driven primarily by organic volume. Geographically, local-currency sales growth increased in all major regions, led by 25 percent growth in Asia Pacific. In addition, both Europe and Latin America/Canada local-currency sales growth exceeded 10 percent.

Sales growth was broad-based across the portfolio, as every business in this segment posted sales increases. Local-currency sales grew by 83 percent in the renewable energy business, 25 percent in energy and advanced materials, 18 percent in the abrasives business, and 17 percent in the automotive OEM business.

Industrial and Transportation rebounded from sales declines in the third quarter and first nine months of 2009. While a pick-up in the economy has helped, this segment has driven growth through new products and has also expanded market share in certain of its businesses. This segment has significantly reduced structural costs in the past two years; thus, the operating leverage gained when sales increase has been quite significant.

Operating income was up 14 percent to $446 million in the third quarter, with operating income margins of 20.2 percent. In the third quarter of 2009, this business segment recorded charges of $21 million related to restructuring actions, with this charge primarily comprised of employee-related liabilities for severance and benefits.

First nine months of 2010:

Sales in Industrial and Transportation increased 21.8 percent to $6.4 billion. In local-currency terms, sales increased 20.1 percent, driven almost entirely by organic volume. Foreign currency impacts added 1.7 percent to first nine months sales growth. Geographically, local-currency sales growth increased in all major regions, led by Asia Pacific. Like the third quarter, sales growth was broad-based across the portfolio, led by the renewable energy business, automotive OEM business, energy and advanced materials, abrasives business, and industrial adhesives and tapes business.

Operating income increased 61 percent to $1.4 billion in the first nine months of 2010, with operating income margins of 21.4 percent. In the first nine months of 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.

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, dental and orthodontic products (oral care), health information systems, inhalation and transdermal drug delivery systems, and food safety products.

Third quarter of 2010:

Health Care sales were $1.1 billion, up 1.6 percent in local currency. Foreign currency impacts decreased third quarter sales growth by 0.4 percent. The most evident impact in the third quarter was the reduced H1N1-related demand, which decreased year-on-year sales growth by approximately 2 percent. The skin and wound care, health information systems, drug delivery systems, and oral care businesses had positive local-currency sales growth. The infection prevention business, impacted by lower year-on-year H1N1-related sales, experienced a sales decline. On a geographic basis, local-currency sales increased 11 percent in Latin America/ Canada and 9 percent in Asia Pacific. In Western Europe and the United States, local-currency sales were down slightly. Hospital admissions were down and elective procedures were being postponed due to macroeconomic uncertainty.

Operating income decreased 3.9 percent to $326 million, and operating income margins were 29.8 percent. In the third quarter of 2009, this business segment recorded charges of $1 million related to restructuring actions, with this charge comprised of employee-related liabilities for severance and benefits.

First nine months of 2010:

Health Care local-currency sales increased 4.9 percent. Currency impacts increased sales by 1.0 percent. On a geographic basis, all regions posted positive local-currency sales growth, led by Latin America/Canada and Asia Pacific. Local currency sales growth was broad-based, led by skin and wound care, drug delivery systems, oral care, health information systems, and infection prevention.

Third quarter of 2010:

Sales in Consumer and Office increased 11.2 percent in the third quarter and exceeded $1.0 billion for the first time ever. Local-currency sales increased 11.1 percent, which included 9.0 percent from organic growth and 2.1 percent from acquisitions. Acquisition growth in the third quarter was primarily comprised of the April 2010 acquisition of the A-One branded label business and related operations. A-One is the largest branded label business in Asia and the second largest worldwide. Foreign currency impacts had a minimal impact on third quarter sales growth.

Accelerated investments in advertising and promotion, which rose over 30 percent year-on-year, drove strong broad-based sales growth. Sales growth was led by office supply products and do-it-yourself products, with local-currency sales growth in excess of 10 percent. The home care and stationery products businesses experienced local-currency sales growth in excess of 5 percent. On a geographic basis, sales growth was broadly dispersed, with Asia Pacific up 27 percent, Latin America/Canada up 21 percent and the United States up 9 percent.

Consumer and Office operating income increased 3.9 percent to $235 million, with operating income margins of 22.9 percent.

First nine months of 2010:

Sales in Consumer and Office increased 11.9 percent in the first nine months of 2010 to $2.9 billion. Local-currency sales increased 10.5 percent, which included 7.4 percent from organic growth and 3.1 percent from acquisitions. Acquisition growth for the first nine months of 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.

The Display and Graphics segment serves markets that include electronic display, traffic safety and commercial graphics. This segment includes optical film solutions for LCD electronic displays; computer screen filters; reflective sheeting for transportation safety; commercial graphics systems; and projection systems, including mobile display technology and visual systems products.

Third quarter of 2010:

Sales in Display and Graphics were $1.1 billion, up 18.8 percent year-on-year. Sales increased 18.4 percent in local currencies, which was entirely organic. Foreign currency impacts had a minimal impact on sales growth. Sales growth was led by 3M’s optical systems business, where sales were up 28 percent in local currency, driven by new 3M film solutions for LED-back-lit televisions. September 2010 sales were negatively impacted by distribution channel inventory adjustments in the LCD TV industry, which 3M expects to continue into the fourth quarter of 2010. 3M’s film attachment rates remain strong. The commercial graphics business continued to strengthen, while sales also increased in traffic safety systems and mobile interactive solutions. Geographically, sales growth was led by Asia Pacific, Latin America/Canada, and the United States.

Operating income in the third quarter of 2010 totaled $282 million, or 26.4 percent of sales. Factory utilization was much improved versus last year’s challenging first nine months. In the third quarter of 2009, adjustments to previously recorded restructuring charges resulted in a $2 million gain.

First nine months of 2010:

Sales in Display and Graphics were $3.0 billion, up 28.8 percent year-on-year. Sales increased 27.5 percent in local currencies, which was entirely organic. Foreign currency impacts increased sales growth by 1.3 percent. As in the third quarter, sales growth was led by 3M’s optical systems business, where sales were up 56 percent in local currency. Commercial graphics and mobile interactive solutions also posted strong sales growth. Sales were up slightly in the traffic safety systems business. Geographically, sales growth was led by Asia Pacific, Latin America/Canada, and the United States.

Operating income in the first nine months of 2010 totaled $802 million, or 26.9 percent of sales. In the first nine months of 2009, this business segment recorded charges of $22 million related to restructuring actions, with this charge comprised of employee-related liabilities for severance and benefits and fixed asset impairments.

The Safety, Security and Protection Services segment serves a broad range of markets that increase the safety, security and productivity of workers, facilities and systems. Major product offerings include personal protection products, safety and security products (including border and civil security solutions), cleaning and protection products for commercial establishments, track and trace solutions, and roofing granules for asphalt shingles.

Third quarter of 2010:

Safety, Security and Protection Services sales decreased 2.5 percent in the third quarter of 2010.  Local-currency sales growth declined 1.6 percent, and foreign currency effects reduced third-quarter sales by 0.9 percent. Year-on-year H1N1-related comparisons reduced total business segment sales growth by approximately 10 percent. Sales in the occupational health and environmental safety business declined 5 percent, but rose 13 percent excluding the impact of H1N1. Sales growth was led by security systems, corrosion protection and building and commercial services. The roofing granules business was sluggish due to stagnant residential construction after a good start to the year. Geographic sales growth was led by Asia Pacific and Latin America/Canada. Sales in the United States and Europe were down year-on-year.

Operating income for the third quarter of 2010 was $164 million, with a 20.2 percent margin. The operating income decline of 27.8 percent was largely attributable to year-on-year H1N1-related comparisons and volume declines in roofing granules, both of which 3M considers to be temporary effects. Operating income margins in the fourth quarter of 2010 will still be impacted by these same two factors and the effects of the acquisitions of Cogent Inc. and Attenti Holdings S.A.

First nine months of 2010:

Safety, Security and Protection Services sales increased 8.3 percent in the first nine months of 2010. Local-currency sales growth was 7.2 percent, and foreign currency effects added 1.1 percent. 3M’s personal protection business was the largest contributor to the year-to-date sales increase. Year-to-date sales growth was also strong in security systems and building and commercial services. Geographically, sales growth was broad-based.

Operating income for the first nine months of 2010 was $542 million, with a 22.0 percent margin. In the first nine months of 2009, this business segment recorded charges of $16 million related to restructuring actions, with this charge comprised of employee-related liabilities for severance and benefits. This charge was largely offset by a gain of $15 million related to the sale of 3M’s New Jersey roofing granule facility.

Operating income was $173 million in the third quarter, or 22.4 percent of sales. The third quarter of 2009 included charges of $1 million related to restructuring actions, with this charge comprised of employee-related liabilities for severance and benefits.

First nine months of 2010:

Electro and Communications sales were $2.2 billion in the first nine months of 2010, an increase of 31.3 percent in U.S. dollars and 29.6 percent in local currency. Foreign currency impacts added 2.4 percent to first nine months sales growth, while divestiture impacts reduced sales by 0.7 percent. Sales expanded in all geographic regions, led by Asia Pacific and the United States. Sales growth was led by businesses that supply the consumer electronics and semiconductor industries. 3M also saw strong growth in the electrical markets business. The telecom infrastructure-related business declined slightly year-on-year, but as discussed above, did show improvement in the third quarter.

Operating income was $475 million in the first nine months of 2010, or 22.0 percent of sales, which was significantly improved versus last year as consumer electronic businesses showed significant year-on-year improvements. The first nine months of 2009 included charges of $11 million related to restructuring actions, with this charge comprised of employee-related liabilities for severance and benefits.

FINANCIAL CONDITION AND LIQUIDITY

The strength of 3M’s capital structure and consistency of its cash flows provide 3M reliable access to capital markets. Additionally, the Company generates significant ongoing cash flow. As indicated in the following table, 3M’s cash, cash equivalents, and marketable securities exceeded total debt at September 30, 2010 by $538 million, compared to $1.1 billion of net debt at December 31, 2009. At September 30, 2010, 3M had $6.3 billion of cash, cash equivalents, and marketable securities and $5.8 billion of debt. Debt included $5.105 billion of long-term debt, $579 million related to the current portion of long-term debt and other borrowings of $74 million. The current portion of long-term debt included $350 million in Dealer Remarketable Securities, which ultimately matures in December 2010.

The Company’s net debt position is as follows:

	Sept. 30,			Dec. 31,
(Millions)	2010			2009
Total Debt	$	5,758		$	5,710
Less: Cash and cash equivalents and marketable securities	6,296			4,609
Net Debt	$	(538	)	$	1,101

Cash, cash equivalents and marketable securities at September 30, 2010 increased by $1.7 billion when compared to year-end 2009, helped by $3.5 billion of cash flows from operating activities in the first nine months of 2010. The Company has sufficient liquidity to meet currently anticipated growth plans, including capital expenditures, working capital investments and acquisitions. As discussed in Note 2, in October 2010, the Company purchased Arizant, Inc., Attenti Holdings S.A. and a controlling interest in Cogent Inc. As a result, inclusive of the impact of acquiring the remaining interest of Cogent Inc., expected cash outflows (including repayment of acquired debt, but net of cash and marketable securities acquired) for these three acquisitions is expected to total approximately $1.4 billion in the fourth quarter of 2010. Due to its strong balance sheet, 3M was able to complete these acquisitions without incurring additional debt. However, cash balances are expected to be lower at year-end 2010. The Company does not utilize derivative instruments linked to the Company’s stock. However, the Company does have contingently convertible debt that, if conditions for conversion are met, is convertible into shares of 3M common stock (refer to Note 10 in 3M’s Current Report on Form 8-K dated May 17, 2010, which updated 3M’s 2009 Annual Report on Form 10-K).

The Company’s financial condition and liquidity are strong. Various assets and liabilities, including cash and short-term debt, can fluctuate significantly from month to month depending on short-term liquidity needs. Working capital (defined as current assets minus current liabilities) totaled $8.653 billion at September 30, 2010, compared with $5.898 billion at December 31, 2009, an increase of $2.755 billion, driven by an increase in cash, cash equivalents, and short-term marketable securities.

Primary short-term liquidity needs are met through U.S. commercial paper and euro commercial paper issuances. The Company maintains a commercial paper program that allows 3M to have a maximum of $3 billion outstanding with a maximum maturity of 397 days from date of issuance. As of September 30, 2010 and December 31, 2009, 3M had no outstanding commercial paper. The Company believes it is unlikely that its access to the commercial paper market will be restricted. Effective April 30, 2007, the Company has a $1.5 billion five-year credit facility, which has provisions for the Company to request an increase of the facility up to $2 billion (at the lenders’ discretion), and providing for up to $150 million in letters of credit. As of September 30, 2010, approximately $131 million was utilized for letters of credit in connection with normal business activities. Debt covenants do not restrict the payment of dividends.

The Company has a “well-known seasoned issuer” shelf registration statement, effective February 17, 2009, which registers an indeterminate amount of debt or equity securities for future sales. No securities have been issued under this shelf. The Company intends to use the proceeds from future securities sales off this shelf for general corporate purposes. In connection with a prior “well-known seasoned issuer” shelf registration, in June 2007 the Company established a $3 billion medium-term notes program. Three debt securities have been issued under this medium-term notes program. First, in December 2007, 3M issued a five-year, $500 million, fixed rate note with a coupon rate of 4.65%. Second, in August 2008, 3M issued a five-year, $850 million, fixed rate note with a coupon rate of 4.375%. Third, in October 2008, the Company issued a three-year $800 million, fixed rate note with a coupon rate of 4.50%. The Company entered into an interest rate swap to convert this $800 million note to a floating rate.

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. 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. Under its $1.5 billion five-year credit facility agreement, 3M is required to maintain its EBITDA to Interest Ratio as of the end of each fiscal quarter at not less than 3.0 to 1. This is calculated (as defined in the agreement) as the ratio of consolidated total

55

EBITDA for the four consecutive quarters then ended to total interest expense on all funded debt for the same period. At September 30, 2010, this ratio was approximately 34.5 to 1.

3M’s strong balance sheet and liquidity provide the Company with significant flexibility to take advantage of numerous opportunities going forward. The Company will continue to invest in its operations to drive growth, including continual review of acquisition opportunities. 3M has a long history of dividend increases. In February 2010, the Board of Directors increased the quarterly dividend on 3M common stock by 2.9 percent to 52.5 cents per share, equivalent to an annual dividend of $2.10 per share. 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 until the remaining amount is fully utilized. Stock repurchases under the Board authorization totaled $370 million in the first nine months of 2010, with the majority of these purchases in the second quarter of 2010. At September 30, 2010, the Company has $2.2 billion remaining under this authorization.

For the nine months ended September 30, 2010, the Company contributed $392 million to its U.S. and international pension plans and $39 million to its postretirement plans. During the fourth quarter of 2010, the Company expects to contribute approximately $100 million to its U.S. and international pension and postretirement plans. The Company does not have a required minimum pension contribution obligation for its U.S. plans in 2010. However, the Company is considering making an additional discretionary contribution of $700 million in cash to its pension plans in either the fourth quarter of 2010 or first quarter of 2011, assuming that both September 30, 2010 discount rates hold and that September-to-date 2010 asset rate of return performance levels hold. The actual contribution may differ. If rates of return or discount rates become more favorable, 3M would likely contribute much less than this amount. The amount of the anticipated discretionary contribution could vary significantly depending on the U.S. qualified plans’ funded status as of the 2010 measurement date and the anticipated tax deductibility of the contribution. Future contributions will also depend on market conditions, interest rates and other factors. 3M believes its strong cash flow and balance sheet will allow it to fund future pension needs without compromising growth opportunities.

As discussed in Note 9, in the fourth quarter of 2010, the Company approved and communicated various changes to its U.S. postretirement benefit plans. The Company will be providing eligible participants with a savings account benefits-based plan, which replaces the current 3M Retiree Medical Plan. The savings account benefits-based plan can be used to help pay for medical premiums or qualified medical expenses. These changes become effective beginning January 1, 2013, for all Medicare eligible retirees and their Medicare eligible dependents and January 1, 2015, for all non-Medicare eligible retirees and their eligible dependents. These changes are expected to increase the 2010 accumulated benefit obligation by $65 million.

The Company uses various working capital measures that place emphasis and focus on certain working capital assets and liabilities. These measures are not defined under U.S. generally accepted accounting principles and may not be computed the same as similarly titled measures used by other companies. One of the primary working capital measures 3M uses is a combined index, which includes accounts receivable, inventory and accounts payable. This combined index (defined as current quarterly net sales multiplied by four, divided by the sum of ending net accounts receivable plus inventory less accounts payable) was 5.1 at September 30, 2010, down from 5.5 at December 31, 2009, but unchanged from 5.1 at September 30, 2009. Receivables increased $619 million, or 19 percent, compared with December 31, 2009, with higher September 2010 sales compared to December 2009 sales contributing to this increase. Inventories increased $576 million, or 22 percent, compared with December 31, 2009. While sales increased 11 percent when comparing third-quarter 2010 to third-quarter 2009, ending September year-on-year net accounts receivable balances only increased 6 percent, while inventory balances increased 22 percent. The inventory increases are partially attributable to the rapid increase in demand over the past three quarters. Accounts payable increased $196 million compared with December 31, 2009.

Cash flows from operating, investing and financing activities are provided in the tables that follow. Individual amounts in the Consolidated Statement of Cash Flows exclude the effects of acquisitions, divestitures and exchange rate impacts on cash and cash equivalents, each of which are presented separately in the cash flows. Thus, the amounts presented in the following operating, investing and financing activities tables reflect changes in balances from period to period adjusted for these effects.

Cash flows from operating activities can fluctuate significantly from period to period, as pension funding decisions, tax timing differences and other items can significantly impact cash flows.

In the first nine months of 2010, cash flows provided by operating activities decreased $354 million compared to the first nine months of 2009. The main positive contributions to operating cash flows related to year-on-year increases in net income including noncontrolling interest and improvements from other-net. The category, “Other-net,” in the preceding table reflects changes in other asset and liability accounts. These positive contributions were more than offset by year-on-year working capital increases of $1.095 billion (which includes accounts receivable, inventories and accounts payable). These working capital increases were partially attributable to the rapid increase in demand over the past three quarters. In addition, cash income taxes were $452 million higher year-on-year and pension contributions were $168 million higher year-on-year.

Cash Flows from Investing Activities:

Investments in property, plant and equipment enable growth in many diverse markets, helping to meet product demand and increasing manufacturing efficiency. Capital expenditures were $565 million in the first nine months of 2010, a decrease of $64 million when compared to the first nine months of 2009. 3M expects to invest approximately $1 billion on capital expenditures in 2010, compared with $903 million for 2009. In 2009, in response to global economic conditions at that point in time, 3M focused its capital expenditures on carryover projects from 2008 and tooling needed for new products and continued operations.

Refer to Note 2 for information on 2010 acquisitions. The Company is actively considering additional acquisitions, investments and strategic alliances, and from time to time may also divest certain businesses.

Purchases of marketable securities and investments and proceeds from sale (or maturities) of marketable securities and investments are primarily attributable to asset-backed securities, agency securities, corporate medium-term note securities and other securities, which are classified as available-for-sale. Interest rate risk and credit risk related to the underlying collateral may impact the value of investments in asset-backed securities, while factors such as general conditions in the overall credit market and the nature of the underlying collateral may affect the liquidity of investments

57

in asset-backed securities. The coupon interest rates for asset-backed securities are either fixed rate or floating. Floating rate coupons reset monthly or quarterly based upon the corresponding monthly or quarterly LIBOR rate. Each individual floating rate security has a coupon based upon the respective LIBOR rate +/- an amount reflective of the credit risk of the issuer and the underlying collateral on the original issue date. Terms of the reset are unique to individual securities. Fixed rate coupons are established at the time the security is issued and are based upon a spread to a related maturity treasury bond. The spread against the treasury bond is reflective of the credit risk of the issuer and the underlying collateral on the original issue date. 3M does not currently expect risk related to its holdings in asset-backed securities to materially impact its financial condition or liquidity. Refer to Note 7 for more details about 3M’s diversified marketable securities portfolio, which totaled $1.830 billion as of September 30, 2010. Purchases of marketable securities and investments, net of proceeds from sales or maturities, totaled $268 million and $443 million in the first nine months of 2010 and 2009, respectively. Purchases of investments also include additional survivor benefit insurance and equity investments.

As discussed in Notes 5 and 8, during the quarter ended March 31, 2010, the Company’s majority owned Sumitomo 3M Limited entity (Sumitomo 3M) purchased a portion of its shares held by its noncontrolling interest, Sumitomo Electric Industries, Ltd. (SEI), by paying cash of 5.8 billion Japanese Yen and entering into a note payable to SEI of 17.4 billion Japanese Yen (approximately $63 million and $188 million, respectively, based on applicable exchange rates at that time). The cash paid during the quarter ended March 31, 2010 as a result of the purchase of Sumitomo 3M shares from SEI is classified as investing activity in the consolidated statement of cash flows. The remainder of the purchase financed by the note payable to SEI is considered non-cash investing and financing activity in the first quarter of 2010. As discussed in Notes 2 and 8, during the second quarter of 2010, 3M recorded a financed liability of 1.7 billion Japanese yen (approximately $18 million based on applicable exchange rates at that time), which is also considered a non-cash investing and financing activity.

Total debt at September 30, 2010 was $5.758 billion, up slightly from $5.710 billion at year-end 2009. Total debt was 27 percent of total capital (total capital is defined as debt plus equity), compared with 30 percent at year-end 2009. For the nine months ended September 30, 2010, a portion of repayment of debt relates to the 5.8 billion Japanese Yen installment paid on September 30, 2010 (refer to Notes 5 and 8 for more detail). For the nine months ended September 30, 2009, the net change in short-term debt and repayment of debt (maturities greater than 90 days) is primarily due to commercial paper activity.

Repurchases of 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 until the remaining amount is fully utilized. In the first nine months of 2010, the Company purchased $415 million of treasury stock, with the majority of these stock repurchases in the second quarter of 2010. The Company had minimal purchases of treasury stock in the first nine months of 2009. As of September 30, 2010, approximately $2.2 billion remained available for future purchases. For more information, refer to the table titled “Issuer Purchases of Equity Securities” in Part II, Item 2.

Cash dividends paid to stockholders totaled $1.124 billion in the first nine months of 2010 compared to $1.070 billion in the first nine months of 2009. 3M has paid dividends since 1916. In February 2010, the Board of Directors increased the quarterly dividend on 3M common stock by 2.9 percent to 52.5 cents per share, equivalent to an annual dividend of $2.10 per share. This marked the 52nd consecutive year of dividend increases. Other cash flows from financing activities primarily include distributions to noncontrolling interests, changes in cash overdraft balances, and principal payments for capital leases.

PART II.  Other Information

Item 1. Legal Proceedings.

Discussion of legal matters is incorporated by reference from Part I, Item 1, Note 12, “Commitments and Contingencies”, of this document, and should be considered an integral part of Part II, Item 1, “Legal Proceedings”.

Item 1A. Risk Factors.

The most significant risk factors applicable to the Company are as follows:

* 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 63 percent of its revenues from outside the United States. The Company’s business may be adversely affected by factors in the United States and other countries that are beyond its control, such as disruptions in financial markets or downturns in economic activity 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; 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, 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 63 percent 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.

60

* 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.

* The Company’s future results may be affected by various legal and regulatory proceedings, including those involving product liability, antitrust, environmental 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 12.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(e) Issuer Purchases of Equity Securities

Repurchases of 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 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 until the remaining $2.2 billion (as of September 30, 2010) is fully utilized.
