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.

Certain amounts presented for prior periods have been reclassified to conform to the current year presentation. As discussed later in Note 1, effective January 1, 2009, 3M adopted two new accounting standards related to noncontrolling interests in consolidated financial statements and the accounting for convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement). Both of these new accounting standards required retrospective application. In addition, 3M reclassified balance sheet amounts related to life insurance policies from investments to other assets; reclassified current and non-current balance sheet amounts related to income taxes between deferred income taxes and accrued income taxes; and reclassified amounts between unearned compensation and additional paid-in-capital, both of which are within stockholders’ equity.

As described in 3M’s Current Report on Form 8-K filed May 13, 2009 (which updated 3M’s 2008 Annual Report on Form 10-K) and 3M’s Quarterly Report on Form 10-Q for the period ended March 31, 2009, during the first quarter of 2009 the Company reorganized its business segments and as discussed above, also reclassified certain amounts presented for prior periods to conform to the current year presentation. 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 filed May 13, 2009.

3M has evaluated subsequent events through the date that the financial statements were issued, which was October 30, 2009, the date of 3M’s Quarterly Report on Form 10-Q for the period ended September 30, 2009.

Foreign Currency Translation

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 13, 2009 (which updated 3M’s 2008 Annual Report on Form 10-K), 3M generally considers local currencies as the functional currencies outside the United States. The Company has a subsidiary in Venezuela with operating income representing less than 1.5 percent of 3M’s consolidated operating income for both 2008 and the nine-month period ended September 30, 2009. 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, an economy is considered highly inflationary when its cumulative inflation is approximately 100 percent or more over a three-year period. 3M evaluates the potential highly inflationary status of Venezuela’s economy by considering both the Consumer Price Index (which largely is associated with the cities of Caracas and Maracaibo) and the National Consumer Price Index (developed commencing in 2008 and covering the entire country of Venezuela). Through September 30, 2009, this evaluation indicated that Venezuela was approaching a highly inflationary status. Under ASC 830, 3M will likely be required to use the dollar as the functional currency of its Venezuelan subsidiary as of the beginning of the applicable fiscal quarter, should the Venezuelan economy be considered highly inflationary in a future fiscal quarter.

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 (43.0 million average options for the three months ended September 30, 2009; 62.1 million average options for the nine months ended September 30, 2009; 43.7 million average options for the three months ended September 30, 2008; 34.5 million average options for the nine months ended September 30, 2008). The conditions for conversion related to the Company’s “Convertible Notes” were not met (refer to 3M’s Current Report on Form 8-K filed May 13, 2009, 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:

Earnings Per Share Computations

New Accounting Standards

In June 2009, the Financial Accounting Standards Board (FASB) issued a standard that established the FASB Accounting Standards CodificationTM (ASC) and amended the hierarchy of generally accepted accounting principles (GAAP) such that the ASC became the single source of authoritative nongovernmental U.S. GAAP. The ASC did not change current U.S. GAAP, but was intended to simplify user access to all authoritative U.S. GAAP by providing all the authoritative literature related to a particular topic in one place. All previously existing accounting standard documents were superseded and all other accounting literature not included in the ASC is considered non-authoritative. New accounting standards issued subsequent to June 30, 2009 are communicated by the FASB through Accounting Standards Updates (ASUs). For 3M, the ASC was effective July 1, 2009. This standard did not have an impact on 3M’s consolidated results of operations or financial condition. However, throughout the notes to the consolidated financial statements references that were previously made to various former authoritative U.S. GAAP pronouncements have been changed to coincide with the appropriate section of the ASC.

In September 2006, the FASB issued an accounting standard codified in ASC 820, Fair Value Measurements and Disclosures. This standard established a single definition of fair value and a framework for measuring fair value, set out a fair value hierarchy to be used to classify the source of information used in fair value measurements, and required disclosures of assets and liabilities measured at fair value based on their level in the hierarchy. This standard applies under other accounting standards that require or permit fair value measurements. As disclosed in the notes included in 3M’s Current Report on Form 8-K filed May 13, 2009, 3M adopted the standard as amended by subsequent FASB standards beginning January 1, 2008 on a prospective basis. One of the amendments deferred the effective date for one year relative to nonfinancial assets and liabilities that are measured at fair value, but are recognized or disclosed at fair value on a nonrecurring basis. This deferral applied to such items as nonfinancial assets and liabilities initially measured at fair value in a business combination (but not measured at fair value in subsequent periods) or nonfinancial long-lived asset groups measured at fair value for an impairment assessment.  These remaining aspects of the fair value measurement standard were adopted by the Company prospectively beginning January 1, 2009 and did not have a material impact on 3M’s consolidated results of operations or financial condition.  Refer to Note 10 for additional disclosures of assets and liabilities that are measured at fair value on a nonrecurring basis as a result of this adoption.

In December 2007, the FASB issued and, in April 2009, amended a new business combinations standard codified within ASC 805, which changed the accounting for business acquisitions. Accounting for business combinations under this standard requires the acquiring entity in a business combination to recognize all (and only) the assets acquired and liabilities assumed in the transaction and establishes the acquisition-date fair value as the measurement objective for all assets acquired and liabilities assumed in a business combination. Certain provisions of this standard impact the determination of acquisition-date fair value of consideration paid in a business combination (including contingent consideration); exclude transaction costs from acquisition accounting; and change accounting practices for acquisition-related restructuring costs, in-process research and development, indemnification assets, and tax benefits. For 3M, this standard was effective for business combinations and adjustments to an acquired entity’s deferred tax asset and liability balances occurring after December 31, 2008. This standard had no immediate impact upon adoption by 3M, and was applied to the business combinations disclosed in Note 2 that were completed post-2008 and to applicable adjustments to acquired entity deferred tax items occurring after December 31, 2008.

In December 2007, the FASB issued a new standard which established the accounting for and reporting of noncontrolling interests (NCIs) in partially owned consolidated subsidiaries and the loss of control of subsidiaries. Certain provisions of this standard indicate, among other things, that NCIs (previously referred to as minority interests) be treated as a separate component of equity, not as a liability (as was previously the case); that increases and decreases in the parent’s ownership interest that leave control intact be treated as equity transactions, rather than as step acquisitions or dilution gains or losses; and that losses of a partially owned consolidated subsidiary be allocated to the NCI even when such allocation might result in a deficit balance. This standard also required changes to certain presentation and disclosure requirements. For 3M, the standard was effective beginning January 1, 2009. The provisions of the standard were applied to all NCIs prospectively, except for the presentation and disclosure requirements, which were applied retrospectively to all periods presented. As a result, upon adoption, 3M retroactively reclassified the “Minority interest in subsidiaries” balance previously included in the “Other liabilities” section of the consolidated balance sheet to a new component of equity with respect to NCIs in consolidated subsidiaries. The adoption also impacted certain captions previously used on the consolidated statement of income, largely identifying net income including NCI and net income attributable to 3M.  Additional disclosures required by this standard are also included in Note 5. The adoption of this standard did not have a material impact on 3M’s consolidated financial position or results of operations.

In December 2007, the FASB ratified a standard related to accounting for collaborative arrangements which discusses how parties to a collaborative arrangement (which does not establish a legal entity within such arrangement) should account for various activities. The standard indicates that costs incurred and revenues generated from transactions with third parties (i.e. parties outside of the collaborative arrangement) should be reported by the collaborators on the respective line items in their income statements pursuant to ASC 605-45, Principle Agent Considerations. Additionally, the guidance provides that income statement characterization of payments between the participants in a collaborative arrangement should be based upon existing authoritative standards; analogy to such standards if not within their scope; or a reasonable, rational, and consistently applied accounting policy election. This guidance was effective for 3M beginning January 1, 2009 and applied retrospectively to all periods presented for collaborative arrangements existing as of the date of adoption. The adoption of this standard did not have a material impact on 3M’s consolidated results of operations or financial condition.

In March 2008, the FASB issued an accounting standard related to disclosures about derivative instruments and hedging activities, codified in ASC 815, which requires additional disclosures about an entity’s strategies and objectives for using derivative instruments; the location and amounts of derivative instruments in an entity’s financial statements; how derivative instruments and related hedged items are accounted for under ASC 815,  and how derivative instruments and related hedged items affect its financial position, financial performance, and cash flows. Certain disclosures are also required with respect to derivative features that are credit-risk-related. The standard was effective for 3M beginning January 1, 2009 on a prospective basis. The additional disclosures required by this standard are included in Note 9.

In April 2008, the FASB issued an accounting standard which amended the list of factors an entity should consider in developing renewal or extension assumptions used in determining the useful life of recognized intangible assets under ASC 350, Intangibles - Goodwill and Other.  This new standard applies to (1) intangible assets that are acquired individually or with a group of other assets and (2) intangible assets acquired in both business combinations and asset acquisitions. Under this standard, entities estimating the useful life of a recognized intangible asset must consider their historical experience in renewing or extending similar arrangements or, in the absence of historical experience, must consider assumptions that market participants would use about renewal or extension. For 3M, this standard required certain additional disclosures beginning January 1, 2009 (which are included in Notes 2 and 3) and application to useful life estimates prospectively for intangible assets acquired after December 31, 2008. The adoption of this standard did not have a material impact on 3M’s consolidated results of operations or financial condition.

In May 2008, the FASB issued an accounting standard which addresses convertible debt securities that, upon conversion by the holder, may be settled by the issuer fully or partially in cash (rather than settled fully in shares) and specifies that issuers of such instruments should separately account for the liability and equity components in a manner that reflects the issuer’s nonconvertible debt borrowing rate when related interest cost is recognized. This standard was effective for 3M beginning January 1, 2009 with retrospective application to all periods presented. This standard impacted the Company’s “Convertible Notes” (refer to Note 10  to the Consolidated Financial Statements included in 3M’s Current Report on Form 8-K filed May 13, 2009 for more detail), and required that additional interest expense essentially equivalent to the portion of issuance proceeds be retroactively allocated to the instrument’s equity component and be recognized over the period from the Convertible Notes’ issuance on November 15, 2002 through November 15, 2005 (the first date holders of these Notes had the ability to put them back to 3M). 3M adopted this standard in January 2009.  Its retrospective application had no impact on results of operations for periods following 2005, but on post-2005 consolidated balance sheets, it resulted in an increase of approximately $22 million in previously reported opening additional paid in capital and a corresponding decrease in previously reported opening retained earnings.

In November 2008, the FASB ratified a standard related to certain equity method investment accounting considerations. The standard indicates, among other things, that transaction costs for an investment should be included in the cost of the equity-method investment (and not expensed) and shares subsequently issued by the equity-method investee that reduce the investor’s ownership percentage should be accounted for as if the investor had sold a proportionate share of its investment, with gains or losses recorded through earnings. For 3M, the standard was effective for transactions occurring after December 31, 2008. The adoption of this standard did not have a material impact on 3M’s consolidated results of operations or financial condition.

In November 2008, the FASB ratified an accounting standard related to intangible assets acquired in a business combination or asset acquisition that an entity does not intend to use or intends to hold to prevent others from obtaining access (a defensive intangible asset). Under the standard a defensive intangible asset needs to be accounted for as a separate unit of accounting and would be assigned a useful life based on the period over which the asset diminishes in value. For 3M, the standard was effective for transactions occurring after December 31, 2008. The Company considered this standard in terms of intangible assets acquired in business combinations or asset acquisitions that closed after December 31, 2008.

In December 2008, the FASB issued an accounting standard regarding a company’s disclosures about postretirement benefit plan assets.  This standard requires additional disclosures about plan assets for sponsors of defined benefit pension and postretirement plans including expanded information regarding investment strategies, major categories of plan assets, and concentrations of risk within plan assets. Additionally, this standard requires disclosures similar to those required for fair value measurements and disclosures under ASC 820 with respect to the fair value of plan assets such as the inputs and valuation techniques used to measure fair value and information with respect to classification of plan assets in terms of the hierarchy of the source of information used to determine their value (see Note 10). The disclosures under this standard are required for annual periods ending after December 15, 2009. 3M is currently evaluating the requirements of these additional disclosures.

In April 2009, the FASB issued an accounting standard which provides guidance on (1) estimating the fair value of an asset or liability when the volume and level of activity for the asset or liability have significantly declined and (2) identifying transactions that are not orderly. The standard also amended certain disclosure provisions for fair value measurements and disclosures in ASC 820 to require, among other things, disclosures in interim periods of the inputs and valuation techniques used to measure fair value as well as disclosure of the hierarchy of the source of underlying fair value information on a disaggregated basis by specific major category of investment. For 3M, this standard was effective prospectively beginning April 1, 2009. The adoption of this standard did not have a material impact on 3M’s consolidated results of operations or financial condition. The additional disclosures required by this standard are included in Note 10.

In April 2009, the FASB issued an accounting standard which modifies the requirements for recognizing other-than-temporarily impaired debt securities and changes the existing impairment model for such securities. The standard also requires additional disclosures for both annual and interim periods with respect to both debt and equity securities. Under the standard, impairment of debt securities will be considered other-than-temporary if an entity (1) intends to sell the security, (2) more likely than not will be required to sell the security before recovering its cost, or (3) does not expect to recover the security’s entire amortized cost basis (even if the entity does not intend to sell). The standard further indicates that, depending on which of the above factor(s) causes the impairment to be considered other-than-temporary, (1) the entire shortfall of the security’s fair value versus its amortized cost basis or (2) only the credit loss portion would be recognized in earnings while the remaining shortfall (if any) would be recorded in other comprehensive income. The standard requires entities to initially apply its provisions to previously other-than-temporarily impaired debt securities existing as of the date of initial adoption by making a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The cumulative-effect adjustment potentially reclassifies the noncredit portion of a previously other-than-temporarily impaired debt security held as of the date of initial adoption from retained earnings to accumulated other comprehensive income. For 3M, this standard was effective beginning April 1, 2009. The adoption of this standard did not have a material impact on 3M’s consolidated results of operations or financial condition. Additional disclosures required by this standard are included in Note 7.

In April 2009, the FASB issued an accounting standard regarding interim disclosures about fair value of financial instruments. The standard essentially expands the disclosure about fair value of financial instruments that were previously required only annually to also be required for interim period reporting. In addition, the standard requires certain additional disclosures regarding the methods and significant assumptions used to estimate the fair value of financial instruments. This standard was effective for 3M beginning April 1, 2009 on a prospective basis. The additional disclosures required by this standard are included in Note 10.

In May 2009, the FASB issued a new accounting standard regarding subsequent events. This standard incorporates into authoritative accounting literature certain guidance that already existed within generally accepted auditing standards, with the requirements concerning recognition and disclosure of subsequent events remaining essentially unchanged. This guidance addresses events which occur after the balance sheet date but before the issuance of financial statements. Under the new standard, as under previous practice, an entity must record the effects of subsequent events that provide evidence about conditions that existed at the balance sheet date and must disclose but not record the effects of subsequent events which provide evidence about conditions that did not exist at the balance sheet date. This standard added an additional required disclosure relative to the date through which subsequent events have been evaluated and whether that is the date on which the financial statements were issued. For 3M, this standard was effective beginning April 1, 2009. The additional disclosures required by this standard are included in Note 1.

In June 2009, the 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 is effective for new transfers of financial assets beginning January 1, 2010. Because 3M historically does not have significant transfers of financial assets, the adoption of this standard is not expected to have a material impact on 3M’s consolidated results of operations or financial condition.

In June 2009, the FASB issued an accounting standard that revised 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 is effective January 1, 2010. The Company is currently evaluating the impact of this standard, but would not expect it to have a material impact on 3M’s consolidated results of operations or financial condition.

In August 2009, the FASB issued ASU No. 2009-05, Measuring Liabilities at Fair Value, which provides additional guidance on how companies should measure liabilities at fair value under ASC 820. The ASU clarifies that the quoted price for an identical liability should be used. However, if such information is not available, a entity may use, the quoted price of an identical liability when traded as an asset, quoted prices for similar liabilities or similar liabilities traded as assets, or another valuation technique (such as the market or income approach). The ASU also indicates that the fair value of a liability is not adjusted to reflect the impact of contractual restrictions that prevent its transfer and indicates circumstances in which quoted prices for an identical liability or quoted price for an identical liability traded as an asset may be considered level 1 fair value measurements (see Note 10 for a description of level 1 measurements). For 3M, this ASU is effective October 1, 2009. The Company is currently evaluating the impact of this standard, but would not expect it to have a material impact on 3M’s consolidated results of operations or financial condition.

In September 2009, the FASB issued ASU No. 2009-12, Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), that amends ASC 820 to provide guidance on measuring the fair value of certain alternative investments such as hedge funds, private equity funds and venture capital funds. The ASU indicates that, under certain circumstance, the fair value of such investments may be determined using net asset value (NAV) as a practical expedient, unless it is probable the investment will be sold at something other than NAV. In those situations, the practical expedient cannot be used and disclosure of the remaining actions necessary to complete the sale is required. The ASU also requires additional disclosures of the attributes of all investments within the scope of the new guidance, regardless of whether an entity used the practical expedient to measure the fair value of any of its investments. For 3M, this ASU is effective October 1, 2009. The Company is currently evaluating the impact of this standard, but would not expect it to have a material impact on 3M’s consolidated results of operations or financial condition.

In October 2009, the FASB issued 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.

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.

NOTE 2.  Acquisitions

During the nine months ended September 30, 2009, 3M completed four business combinations. The purchase price paid for these business combinations (net of cash acquired) and certain acquisition costs and contingent consideration paid for pre-2009 business combinations during the nine months ended September 30, 2009 aggregated to $67 million.

(1) In January 2009, 3M (Safety, Security and Protection Services Business) purchased 100 percent of the outstanding shares of Alltech Solutions, a provider of water pipe rehabilitation services based in Moncton, New Brunswick, Canada.

(2) In February 2009, 3M (Industrial and Transportation Business) purchased the assets of Compac Corp.’s pressure sensitive adhesive tape business, a global leader in providing custom solutions in coating, laminating and converting flexible substrates headquartered in Hackettstown, N.J.

(3) In April 2009, 3M (Industrial and Transportation Business) purchased 100 percent of the outstanding shares of Meguiar’s International, UK, a distributor of Meguiar’s Inc. products in the United Kingdom based in Daventry, United Kingdom.

(4) In July 2009, 3M (Consumer and Office Business) purchased the ACE® branded (and related brands) elastic bandage and supports product lines and thermometer product line, which are sold broadly through consumer channels in North America.

Purchased identifiable intangible assets related to the four acquisitions which closed in the first nine months of 2009 totaled $28 million. This included $20 million of identifiable intangible assets that will be amortized on a straight-line basis over a weighted-average life of 8 years (lives ranging from 3 to 12 years) and $8 million of indefinite-lived intangible assets related to the well-recognized ACE® brand. 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.

NOTE 3.  Goodwill and Intangible Assets

Purchased goodwill related to the four acquisitions which closed in the first nine months of 2009 totaled $15 million, $9 million of which is deductible for tax purposes. The acquisition activity in the following table also includes the impacts of adjustments to the preliminary allocation of purchase price and certain acquisition costs and contingent consideration for pre-2009 acquisitions, which reduced goodwill by $48 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, 2008 and September 30, 2009, follow:

Goodwill

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 13, 3M made certain changes to its business segments effective in the first quarter of 2009, which resulted in no material changes to the goodwill balances by business segment. For those changes 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 2009, the Company completed its assessment of any potential goodwill impairment for reporting units impacted by this new structure and determined that no impairment existed.

As discussed in Note 10, in June 2009, 3M tested the long lived assets grouping associated with the UK passport production activity of 3M’s Security Systems Division for recoverability. This circumstance required the Company to also test goodwill for impairment at the reporting unit (Security Systems Division) level. 3M completed its assessment of potential goodwill impairment for this reporting unit and determined that no goodwill impairment existed as of June 30, 2009.

Acquired Intangible Assets

For the nine months ended September 30, 2009, intangible assets (excluding goodwill) acquired through business combinations increased balances by $93 million, of which approximately $65 million related to adjustments to preliminary allocations of purchase price on pre-2009 acquisitions. 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, 2009, and December 31, 2008, follow:

Amortization expense for acquired intangible assets for the three and nine months ended September 30, 2009 and 2008 follows:

The table below shows expected amortization expense for acquired intangible assets recorded as of September 30, 2009:

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. 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 first-nine months of 2009 restructuring actions and fourth-quarter 2008 restructuring actions.

2008 and 2009 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. Refer to 3M’s Current Report on Form 8-K filed May 13, 2009, Note 4, for additional information on these 2008 restructuring actions.

·                  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 option. 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 $13 million non-cash charge related to a pension settlement in Japan (discussed further in Note 8), 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 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 and a roll-forward of associated balances are summarized as follows:

The majority of the remaining employee related items and benefits associated with these actions are expected to be paid out in cash in the fourth quarter of 2009 and into 2010.  As discussed in Note 8, a $21 million non-cash charge related to special termination benefits was recorded in the second quarter of 2009 that related to the approximately 700 participants who accepted the voluntary early retirement incentive program offer. Also, as discussed in Note 8, a $13 million non-cash charge related to a pension settlement in Japan was recorded in the third quarter of 2009.
