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 16, 2013 (which updated 3M’s 2012 Annual Report on Form 10-K) and 3M’s Quarterly Report on Form 10-Q for the period ended March 31, 2013, during the first quarter of 2013 the Company completed a realignment of its business segments to better serve global markets and customers (refer to Note 13 herein). In addition, during the first quarter of 2013, 3M realigned its geographic area reporting to include Puerto Rico in the United States rather than in Latin America/Canada region. Segment and geographic 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 16, 2013.

Foreign Currency Translation

Local currencies generally are considered the functional currencies outside the United States. Assets and liabilities for operations in local-currency environments are translated at month-end exchange rates of the period reported. Income and expense items are translated at month-end exchange rates of the period reported. Cumulative translation adjustments are recorded as a component of accumulated other comprehensive income (loss) in shareholders’ equity.

Although local currencies are typically considered as the functional currencies outside the United States, 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 2012. 3M has determined that the cumulative inflation rate of Venezuela has exceeded, and continues to exceed, 100 percent since November 2009. Accordingly, since January 1, 2010, the financial statements of the Venezuelan subsidiary have been remeasured as if its functional currency were that of its parent.

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 had, however, provided an exemption for the purchase and sale of certain securities that 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). However, in 2010, the Venezuelan government took control of the previously freely-traded parallel market and created a government-controlled rate under the Transaction System for Foreign Currency Denominated Securities (SITME). In February 2013, the Venezuelan government announced a devaluation of its currency, the elimination of the SITME market, and the creation of the Superior Body for the Optimization of the Exchange System to oversee its foreign currency exchange policies. As a result, the new official exchange rate changed to a rate less favorable than the previous SITME rate. Since January 1, 2010, as discussed above, the financial statements of 3M’s Venezuelan subsidiary have been remeasured as if its functional currency were that of its parent. This remeasurement utilized the parallel rate through May 2010, the SITME rate through January 2013, and the new official rate discussed above thereafter.

The Company continues to monitor circumstances relative to its Venezuelan subsidiary. Other factors notwithstanding, the elimination of the SITME rate and use of the new official exchange rate beginning in February 2013 did not have a material impact on 3M’s consolidated results of operations or financial condition.

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 (insignificant for the three months ended September 30, 2013; 2.6 million average options for the nine months ended September 30, 2013; 6.3 million average options for the three months ended September 30, 2012; and 15.6 million average options for the nine months ended September 30, 2012). The computations for basic and diluted earnings per share follow:

New Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-11, Disclosures About Offsetting Assets and Liabilities, and in January 2013 issued ASU No. 2013-01, Clarifying the Scope of Disclosures About Offsetting Assets and Liabilities. These standards created new disclosure requirements regarding the nature of an entity’s rights of setoff and related arrangements associated with its derivative instruments, repurchase agreements, and securities lending transactions. Certain disclosures of the amounts of certain instruments subject to enforceable master netting arrangements are required, irrespective of whether the entity has elected to offset those instruments in the statement of financial position. For 3M, these ASUs were effective January 1, 2013 with retrospective application required. The additional disclosures required by these ASUs are included in Note 9. Since these standards impact disclosure requirements only, their adoption did not have a material impact on 3M’s consolidated results of operations or financial condition.

In July 2012, the FASB issued ASU No. 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment. Under this standard, entities testing long-lived intangible assets for impairment now have an option of performing a qualitative assessment to determine whether further impairment testing is necessary. If an entity determines, on the basis of qualitative factors, that the fair value of the indefinite-lived intangible asset is more-likely-than-not less than the carrying amount, the existing quantitative impairment test is required. Otherwise, no further impairment testing is required. For 3M, this ASU was effective beginning January 1, 2013. The adoption of this standard did not have a material impact on 3M’s consolidated results of operations or financial condition.

In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. Under this standard, entities are required to disclose additional information with respect to

changes in accumulated other comprehensive income (AOCI) balances by component and significant items reclassified out of AOCI. Expanded disclosures for presentation of changes in AOCI involve disaggregating the total change of each component of other comprehensive income (for example, unrealized gains or losses on available for sale debt and equity securities) as well as presenting separately for each such component the portion of change in AOCI related to (1) amounts reclassified into income and (2) current-period other comprehensive income. Additionally, for amounts reclassified into income, disclosure in one location is required, based upon each specific AOCI component, of the amounts impacting individual income statement line items. Disclosure of the income statement line item impacts is required only for components of AOCI reclassified into income in their entirety. Therefore, disclosure of the income statement line items affected by AOCI components such as net periodic benefit costs is not included. The disclosures required with respect to income statement line item impacts are to be made in either the notes to the consolidated financial statements or parenthetically on the face of the financial statements. For 3M, this ASU was effective beginning January 1, 2013. The additional disclosures required by this ASU are included in Note 4. Because this standard only impacts presentation and disclosure requirements, its adoption did not have a material impact on 3M’s consolidated results of operations or financial condition.

In March 2013, the FASB issued ASU No. 2013-05, Foreign Currency Matters. This standard provides additional guidance with respect to the reclassification into income of the cumulative translation adjustment (CTA) recorded in accumulated other comprehensive income associated with a foreign entity of a parent company. The ASU differentiates between transactions occurring within a foreign entity and transactions/events affecting an investment in a foreign entity. For transactions within a foreign entity, the full CTA associated with the foreign entity would be reclassified into income only when the sale of a subsidiary or group of net assets within the foreign entity represents the substantially complete liquidation of that foreign entity. For transactions/events affecting an investment in a foreign entity (for example, control or ownership of shares in a foreign entity), the full CTA associated with the foreign entity would be reclassified into income only if the parent no longer has a controlling interest in that foreign entity as a result of the transaction/event. In addition, acquisitions of a foreign entity completed in stages will trigger release of the CTA associated with an equity method investment in that entity at the point a controlling interest in the foreign entity is obtained. For 3M, this ASU is effective prospectively beginning January 1, 2014, with early adoption permitted. This ASU would impact 3M’s consolidated results of operations and financial condition only in the instance of an event/transaction as described above.

NOTE 2.  Acquisitions and Divestitures

Acquisitions:

3M makes acquisitions of certain businesses from time to time that the Company feels align with its strategic intent with respect to, among other factors, growth markets and adjacent product lines or technologies. Goodwill resulting from business combinations is largely attributable to the existing workforce of the acquired businesses and synergies expected to arise after 3M’s acquisition of these businesses. 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.

There were no business combinations that closed during the nine months ended September 30, 2013. Adjustments in the first nine months of 2013 to the preliminary purchase price allocations of other acquisitions within the allocation period were not material and primarily related to the 2012 acquisition of Ceradyne, Inc. The allocation of purchase price related to the acquisition of Ceradyne, Inc. in November 2012 is considered preliminary, largely with respect to certain acquired property, plant and equipment, tax-related items and certain other liabilities. Refer to Note 2 in 3M’s Current Report on Form 8-K dated May 16, 2013 (which updated 3M’s 2012 Annual Report on Form 10-K) for more information on 3M’s 2012 acquisitions.

Divestitures:

In June 2013, 3M (Consumer Business) completed the sale of its Scientific Anglers and Ross Reels businesses to The Orvis Company, Inc. based in Manchester, Vermont.

NOTE 3.  Goodwill and Intangible Assets

There were no acquisitions that closed during the first nine months of 2013. The acquisition activity in the following table includes the net impacts of adjustments to the preliminary allocation of purchase price for prior year acquisitions, which increased goodwill by $3 million. The amounts in the “Translation and other” column in the following table primarily relate to changes in foreign currency exchange rates. The goodwill balances by business segment as of December 31, 2012 and September 30, 2013, 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, effective in the first quarter of 2013, 3M completed a realignment of its business segments. Concurrent with this business segment realignment, certain products were also moved between 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 on goodwill of the associated reporting units. During the first quarter of 2013, 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

3M did not complete any business combinations during the nine months ended September 30, 2013. As a result, gross balances of acquired intangible assets were primarily impacted by changes in foreign currency exchange rates. The carrying amount and accumulated amortization of acquired finite-lived intangible assets, in addition to the balance of non-amortizable intangible assets, as of September 30, 2013, and December 31, 2012, follow:

Amortization expense for acquired intangible assets for the three-month and nine-month periods ended September 30, 2013 and 2012 follows:

The table below shows expected amortization expense for acquired amortizable intangible assets recorded as of September 30, 2013:

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.
