Business Segments

Financial information and other disclosures relating to 3M’s business segments and operations in major geographic areas are provided in the Notes to Consolidated Financial Statements. 3M manages its operations in seven operating business segments: Health Care; Industrial; Display and Graphics; Consumer and Office; Safety, Security and Protection Services; Electro and Communications; and Transportation. 3M’s seven 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. Certain small businesses and staff-sponsored products, as well as various corporate assets and expenses, are not allocated to the business segments.

Effective January 1, 2005, as part of the continuing effort to drive growth by aligning businesses around markets and customers, the Electronics Markets Materials Division and certain high temperature and display tapes (2004 sales of approximately $350 million) within the Industrial Business transferred to the Electro and Communications Business, and the converter markets product line (2004 sales of approximately $10 million) within the Transportation Business transferred to the Display and Graphics Business. Internal management reporting for these business segment transfers commenced January 1, 2005. Segment information for all periods presented has been reclassified to reflect the new segment structure.

Distribution

3M products are sold through numerous distribution channels. Products are sold directly to users and through numerous wholesalers, retailers, jobbers, distributors and dealers in a wide variety of trades in many countries around the world. Management believes the confidence of wholesalers, retailers, jobbers, distributors and dealers in 3M and its products, developed through long association with skilled marketing and sales representatives, has contributed significantly to 3M’s position in the marketplace and to its growth. 3M has 189 sales offices worldwide, with 15 in the United States and 174 internationally.

Research, Patents and Raw Materials

Research and product development constitute an important part of 3M’s activities. Products resulting from research and development have been a major driver of 3M’s growth. Research, development and related expenses totaled $1.143 billion in 2004, $1.102 billion in 2003 and $1.070 billion in 2002. Research and development, covering basic scientific research and the application of scientific advances to the development of new and improved products and their uses, totaled $759 million in 2004, $749 million in 2003 and $738 million in 2002. Related expenses primarily include technical support provided to customers for existing products by 3M laboratories.

3M realigned its research and development efforts in 2003. This realignment was designed to develop technologies needed for the future, to more closely align technical resources with business priorities, and to shorten the distance between research and development and 3M’s customers. 3M established a single global Corporate Research Laboratory, which brings together more than 600 researchers focused on technology building while also freeing up approximately 400 other 3M technical people to directly support the growth of 3M business units.

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

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

In 2004, the Company experienced both price increases and supply limitations affecting several oil-derived raw materials, but to date the Company is receiving sufficient quantities of such materials to meet its reasonably foreseeable production requirements. It is impossible to predict future shortages of raw materials or the impact any such shortages would have.

Environmental Law Compliance

3M’s manufacturing operations are affected by national, state and local environmental laws around the world. 3M has made, and plans to continue making, necessary expenditures for compliance with applicable laws. 3M is also involved in remediation actions relating to environmental matters from past operations at certain sites (refer to Part I, Item 3, Legal Proceedings).

Environmental expenditures relating to existing conditions caused by past operations that do not contribute to current or future revenues are expensed. Environmental expenditures for capital projects that contribute to current or future operations generally are capitalized and depreciated over their estimated useful lives.

In 2004, 3M expended about $17 million for capital projects related to protecting the environment. The comparable amount in 2003 was about $40 million. These amounts exclude expenditures for remediation actions relating to existing matters caused by past operations. Capital expenditures for environmental purposes have included pollution control devices – such as wastewater treatment plant improvements, scrubbers, containment structures, solvent recovery units and thermal oxidizers – at new and existing facilities constructed or upgraded in the normal course of business. Consistent with the Company’s policies stressing environmental responsibility, average annual capital expenditures (other than for remediation projects) are presently expected to be about $23 million over the next two years for new or expanded programs to build facilities or modify manufacturing processes to minimize waste and reduce emissions.

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

OVERVIEW

3M is a diversified global manufacturer, technology innovator and marketer of a wide variety of products. 3M manages its operations in seven operating business segments: Health Care; Industrial; Display and Graphics; Consumer and Office; Safety, Security and Protection Services; Electro and Communications; and Transportation.

Effective January 1, 2005, as part of the continuing effort to drive growth by aligning businesses around markets and customers, the Electronics Markets Materials Division and certain high temperature and display tapes (2004 sales of approximately $350 million) within the Industrial Business transferred to the Electro and Communications Business, and the converter markets product line (2004 sales of approximately $10 million) within the Transportation Business transferred to the Display and Graphics Business. In addition, effective January 1, 2005, the company realigned its reporting for the African Region, which previously was included in the Latin America and Canada area, to the Europe and Middle East area. Internal management reporting for these business segment and geographic area transfers commenced January 1, 2005, with segment and geographic area information for all periods presented adjusted to reflect these new structures.

3M’s performance in 2004 was broad-based, with strong performance and growth in Display and Graphics, but 3M also had success in established businesses like Industrial; Safety, Security and Protection Services; and Consumer and Office. All seven business segments contributed to sales growth in 2004. In 2004, 3M reported record net sales of $20.011 billion and record net income of $2.990 billion, or $3.75 per diluted share, compared with net sales of $18.232 billion and net income of $2.403 billion, or $3.02 per diluted share, in 2003. The combination of a 9.8% increase in net sales, including core volume sales growth of 6.2% (which excludes the impact of businesses acquired in the last 12 months), and declining operating expenses as a percent of sales, resulted in a 22.9% operating income profit margin. The following table contains sales and operating income results by business segment for the years ended December 31.

Sales growth in 2004 was strongest in the Display and Graphics segment, driven by sales of display enhancement films used in flat-panel devices, and the Industrial segment, led by broad-based sales across Industrial businesses and geographies. Sales growth in the Safety, Security and Protection Services segment was driven by continued demand for personal protection products along with strong demand for cleaning and protection products. Sales growth in the Consumer and Office segment was broad-based, with the Transportation segment led by both the automotive OEM and repair markets. The Health Care segment experienced tough year-on-year comparisons through the first three quarters of the year, with improvement in the fourth quarter of 2004. For the Electro and Communications segment, this was the first year of positive local-currency sales growth since 2000. Refer to the Performance by Business Segment section for a more detailed discussion of the results of the respective segments.

Asia Pacific local-currency sales (which excludes translation impacts) increased 13.6%, with the strongest growth in China, Korea and Taiwan. All seven business segments contributed to this increase. U.S. sales revenue increased 3.9%, with growth led by Consumer and Office; Safety, Security and Protection Services; and the Industrial businesses. European local-currency sales increased 0.8%, with growth in Safety, Security and Protection Services; Transportation; Industrial; and Health Care. In the combined Latin America and Canada area, six of seven businesses had local-currency sales increases, led by Electro and Communications; Transportation; Health Care; Industrial; and Consumer and Office. Foreign currency translation positively impacted European sales by 9.0%, Asia Pacific sales by 5.6%, and the combined Latin America and Canada area by 1.8%, as the U.S. dollar weakened against these currencies. Refer to the Performance by Geographic Area section for a more detailed discussion of the results for the respective areas.

Operating income in 2004 increased by 23.3% versus 2003, as all seven business segments posted increases. The combination of solid sales growth and positive benefits from 3M’s 2004 corporate initiatives drove the operating income increase. Cost reduction projects related to these initiatives – Six Sigma, Global Sourcing Effectiveness, 3M Acceleration and eProductivity – contributed over $400 million in aggregate operating income benefits in 2004 (see “Note A” at the end of this Overview section). Currency impacts, related primarily to the weaker U.S. dollar, boosted 2004 operating income by an estimated $286 million, partially offset by increased pension expense of $157 million. Operating income in 2003 was negatively impacted by a $93 million pre-tax charge related to an adverse ruling in a lawsuit filed against 3M in 1997 by LePage’s Inc.

3M generated $4.282 billion of operating cash flows in 2004, a $509 million increase over 2003, and ended the year with $2.757 billion of cash and cash equivalents. Cash flow in 2004 was primarily driven by higher net income. In 2004, the Company utilized $2.916 billion of cash to repurchase 3M common stock and pay dividends, and contributed $591 million to its pension plans. 3M’s debt to total capital ratio (total capital defined as debt plus equity) as of December 31, 2004, was approximately 21%. 3M has an AA credit rating from Standard & Poor’s and an Aa1 credit rating from Moody’s Investors Service.

In 2005, 3M expects to continue its momentum to drive sales, operational efficiency and cash flow growth. 3M is looking for continued broad-based product sales to drive its growth, in addition to expected continued growth in optical film products, and will also continue to assess potential acquisitions. Continued core volume sales growth will require both faster growth of existing products/services and successful introduction of new products. While international sales now represent 61% of worldwide sales, the Company will also focus on execution of sales and growth opportunities in the United States. In part to energize the 3M Acceleration initiative, early in 2004 the Company launched an extensive effort to reconnect and re-engage with customers. This will aid 3M in its continuing quest to provide additional customer value, with both the customer and 3M benefiting through value creation and also facilitating 3M’s ability to achieve appropriate pricing. The Company also is focused on its corporate initiatives to improve productivity and reduce costs. Cost reduction projects related to these initiatives are expected to contribute an additional $400 million to operating income in 2005. The Company has experienced both price increases and supply limitations affecting several oil-derived raw materials, but to date the Company is receiving sufficient quantities of such materials to meet its reasonably foreseeable production requirements. Fluctuations in foreign currency exchange rates also impact results, although the Company minimizes this effect through hedging about half of this impact. 3M will also continue, as it has for many years, to incur expenses (insured and uninsured) in managing its litigation and environmental contingencies. These forward-looking statements involve risks and uncertainties that could cause results to differ materially from those projected (refer to the forward-looking statements discussion later in Item 7 for discussion of these risks and uncertainties).

(Note A). The Company’s five corporate initiatives (Six Sigma, Global Sourcing Effectiveness, 3M Acceleration, eProductivity and Global Business Processes) are aimed at accelerating long-term top-line growth, improving cash flow and lowering its total cost structure. Indirect Cost Control, which focused on reducing costs not directly associated with products or services, is no longer a formal initiative and is now managed using a productivity metric. Six Sigma focuses on higher growth, productivity and cash flow. Global Sourcing Effectiveness generates savings by leveraging purchasing economies of scale, encouraging competition among suppliers, geographic broadening and e-applications. Through its 3M Acceleration initiative, the Company is driving toward more and better new product ideas and faster, more impactful new product introductions, along with reallocating research and development resources to larger, more global projects. In eProductivity, 3M believes it has a significant opportunity to improve productivity for its customers, suppliers and for 3M itself. 3M’s Global Business Processes initiative continues 3M’s ongoing effort to standardize, simplify and strengthen its business processes in order to increase the speed, efficiency and quality of service functions vital to its business operations worldwide. There can be no assurance that all of the estimated cost savings from such activities will be realized. Numerous factors may create offsets to these savings, such as the potential for weakness in sales volumes, normal increases in compensation and benefits, and other inflationary pressures. The Company estimates that cost reduction projects related to initiatives provided a combined incremental benefit to operating income of more than $400 million in 2004, after contributing a similar amount in 2003. These initiatives provided an incremental benefit to operating income of more than $500 million in 2002.

In 2004, core volume growth (which excludes the impact of businesses acquired in the last 12 months) was broad-based, with all seven businesses posting worldwide local-currency sales growth. Local-currency growth was led by Display and Graphics; Industrial; Consumer and Office; Safety, Security and Protection Services; and the Transportation businesses. Health Care local-currency sales increased 1.7%, as results were negatively impacted by 2003 sales from pharmaceutical and drug delivery agreements that did not repeat in 2004. Electro and Communications local-currency sales increased 2.7%, the first year of positive local-currency sales growth since 2000. Acquisitions increased 2004 sales by 0.5%, driven by the 2004 acquisitions of HighJump Software, Inc. and Hornell Holding AB. Internationally, selling prices declined 1.1%, with most of the decline coming in certain businesses that serve the electronics industry, where it is important to look at the combined impact of volume and price. On a geographic basis, local-currency sales growth in 2004 was led by the Asia Pacific area. Refer to both the “Performance by Business Segment” and “Performance by Geographic Area” sections for additional discussion of sales change.

In 2003, core volume growth (which excludes the impact of businesses acquired in the last 12 months) was led by display enhancement films, broad-based growth in most of the Health Care businesses, personal protection products, and growth in products related to construction and home improvement/home care. Acquisitions increased 2003 sales by nearly 2%, driven primarily by the December 2002 acquisition of Corning Precision Lens, Inc. On a geographic basis, 2003 core volume growth was strongest in the Asia Pacific area.

Operating Expenses:

(Percent of net sales)	2004		2003		2002		2004 versus 2003		2003 versus 2002
Cost of sales	49.8	%	50.9	%	52.0	%	(1.1	)%	(1.1	)%
Selling, general and administrative expenses	21.6		22.2		22.8		(0.6	)	(0.6	)

Other expense	—		0.5		—		(0.5	)	0.5
Operating income	22.9		20.4		18.7		2.5		1.7

Cost of Sales:

Cost of sales includes manufacturing, engineering and freight costs. Cost of sales decreased 1.1 percentage points in both 2004 and 2003. The 2004 decrease as a percent of net sales was driven by a combination of higher volumes, productivity gains, ongoing benefits of corporate initiatives and positive currency impacts (including hedging impacts). While 3M raw material costs increased during the year, 3M’s global sourcing initiative was important in enabling 3M to minimize raw material cost increases during a period of commodity price inflation.

Cost of sales in 2003 benefited from Six Sigma and other projects aimed at improving manufacturing throughput, yield and productivity. 3M’s global sourcing initiative has helped mitigate the impact of raw material price increases. In 2003, raw material costs were essentially flat versus 2002. Charges related to the 2001/2002 corporate restructuring program negatively impacted cost of sales by 0.7 percentage points in 2002.

Selling, General and Administrative Expenses:

Selling, general and administrative (SG&A) expenses have improved by 0.6 percentage points in each of the past two years. The improvement in 2004 as a percent of net sales was helped by leverage related to 3M’s strong growth in the Asia Pacific area. SG&A expenses in U.S. dollars increased in 2004, negatively impacted by currency translation and increased advertising and merchandising spending to support 3M’s strong brand portfolio. On an ongoing basis, the Company is shifting SG&A dollars toward faster-growth businesses and geographic areas.

SG&A expenses in U.S. dollars in 2003 increased due to currency translation, as well as higher advertising and merchandising spending. Charges related to the 2001/2002 corporate restructuring program negatively impacted SG&A in 2002 by $77 million, or 0.5% of sales. Excluding these charges, SG&A for 2003 was relatively flat as a percent of sales compared with 2002.

Other Expense:

In 2003, 3M recorded pre-tax charges of $93 million ($58 million after-tax, or 7 cents per diluted share) related to an adverse ruling in a lawsuit filed against 3M in 1997 by LePage’s Inc. The pre-tax charge of $93 million is classified as “Other expense” within operating income. For more detail, refer to the discussion of “Legal Proceedings” in Part I, Item 3 of this document.

2001/2002 Corporate Restructuring Program:

In 2002, charges related to the 2001/2002 corporate restructuring program reduced operating income by $202 million and net income by $108 million. These charges principally related to employee severance and benefit costs, accelerated depreciation charges, and other associated exit costs under the Company’s restructuring plan announced in June 2001. These charges are included in cost of sales ($121 million); selling, general and administrative expenses ($77 million); and research, development and related expenses ($4 million). The 2001/2002 corporate restructuring program actions were substantially completed by June 30, 2002. The Company estimated incremental savings under this plan of approximately $100 million on a pre-tax basis in 2003, primarily in the first half of the year. The Company estimated incremental savings of $300 million on a pre-tax basis in 2002. The majority of these savings were from reduced employee costs. For more detail, refer to the discussion in Note 4 to the Consolidated Financial Statements (2001/2002 Corporate Restructuring Program).

Operating Income:

3M uses operating income as one of its primary business segment performance measurement tools. Operating income in 2004 was 22.9% of sales, up from 20.4% of sales in 2003 and 18.7% of sales in 2002. Operating income in 2004 grew by $865 million, or 23.3 percent, following 2003 operating income growth of $667 million, or 21.9%. The LePage’s Inc. lawsuit negatively impacted operating income in 2003 by $93 million, or 0.5% of sales. The 2001/2002 corporate restructuring program negatively impacted operating income in 2002 by $202 million, or 1.2% of sales.

Interest Expense and Income:

(Millions)	2004			2003			2002
Interest expense	$	69		$	84		$	80
Interest income	(46		)	(28		)	(39		)
Total	$	23		$	56		$	41

Interest Expense: The decrease in 2004 interest expense was primarily the result of lower average debt balances, partially offset by higher interest rates in the United States. The slight increase in 2003 interest expense was primarily due to a reduced benefit from capitalized interest (related to lower capital spending) and higher average debt balances, largely offset by lower interest rates.

Interest Income: Interest income increased in 2004 due to substantially higher cash balances. In 2003, while average cash balances were higher than in 2002, interest income decreased due to lower interest rates.

Provision for Income Taxes:

(Percent of pretax income)		2004		2003		2002
Effective tax rate		33.0	%	32.9	%	32.1	%

The tax rate of 33.0% for 2004 was comparable to the 2003 rate of 32.9%. Income taxes associated with repatriating certain cash from outside the United States negatively impacted the 2004 and 2003 income tax rates. Refer to Note 1 to the Consolidated Financial Statements for discussion of the American Jobs Creation Act of 2004 and the possible impact on the 2005 tax rate.

Minority Interest:

(Millions)	2004		2003		2002
Minority interest	$	62	$	52	$	65

Minority interest represents the elimination of the non-3M ownership interests, primarily in Sumitomo 3M Limited and 3M Inter-Unitek GmbH (in 2002 only). The increase in 2004 related primarily to higher net income in Sumitomo 3M, as 3M eliminates the non-3M ownership portion of net income. The decrease in 2003 related to 3M’s purchase of the minority interest shares of 3M Inter-Unitek GmbH in December 2002 and the purchase of an additional 25% ownership in Sumitomo 3M in early 2003. Refer to Note 2 to the Consolidated Financial Statements for additional information on these acquisitions.

Currency Effects:

3M estimates that year-on-year currency effects, including hedging impacts, increased net income by $181 million in 2004 and $73 million in 2003, and reduced net income by $35 million in 2002. 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.

PERFORMANCE BY BUSINESS SEGMENT

Disclosures relating to 3M’s business segments are provided in Item 1, Business Segments. Financial information and other disclosures are provided in the Notes to the Consolidated Financial Statements. The reportable segments are Health Care; Industrial; Display and Graphics; Consumer and Office; Safety, Security and Protection Services; Electro and Communications; and Transportation. Information related to 3M’s business segments is presented in the tables that follow. Local-currency sales (which include both core and acquisition volume impacts, plus price impacts) are provided for each segment. The translation impact and total sales change are also provided for each segment.

Health Care Business (21.1% of consolidated sales):

	2004			2003			2002
Sales (millions)	$	4,230		$	3,995		$	3,560
Sales change analysis:
Local currency (volume and price)	1.7		%	6.0		%	7.7		%
Translation	4.2			6.2			0.2
Total sales change	5.9		%	12.2		%	7.9		%

Operating income (millions)	$	1,123		$	1,027		$	900
Percent change	9.3		%	14.1		%	19.5		%
Percent of sales	26.5		%	25.7		%	25.3		%

The Health Care segment serves markets that include medical, surgical, pharmaceutical, dental and orthodontic, health information systems and personal care. Products provided to these markets include medical and surgical supplies, skin health and infection prevention products, pharmaceuticals, drug delivery systems, dental and orthodontic products, health information systems, microbiology products, and closures for disposable diapers.

In 2004, local-currency sales in Health Care increased 1.7%, with the first nine months of 2004 negatively impacted by 2003 pharmaceutical and drug delivery agreements that did not repeat. Fourth quarter 2004 local-currency sales grew 5.0%, as year-on-year comparisons became more favorable. Operating income increased 9.3% to $1.123 billion in 2004.

The 3M product platform of immune response modifiers (IRMs) continues to progress. 3M received U.S. Food and Drug Administration (FDA) approval in March 2004 to market Aldara™ (imiquimod) Cream, 5%, for the treatment of certain types of actinic keratosis (a pre-cancerous skin condition). In July 2004, the FDA granted approval for Aldara for the treatment of superficial basal cell carcinoma (a common form of non-melanoma skin cancer). The patent and related rights for the imiquimod molecule are important to the Health Care Business. The original patent on the imiquimod molecule expired in August 2004, but the patent term extension runs through August 2009.

In the pharmaceuticals business, an agreement was reached with Eli Lilly and Company in September of 2001 to collaborate on resiquimod, an investigational compound for the treatment of genital herpes. 3M received $100 million in the fourth quarter of 2001 from Lilly in consideration for research and development efforts. Revenue was recognized on a pro-rata basis over the service period. 3M recognized $44 million of revenue relating to this agreement in 2003, $43 million in 2002 and $7 million in 2001. In the third quarter of 2003, 3M and Eli Lilly reached a final agreement to return control of resiquimod to 3M. Upon termination of the agreement in 2003, 3M recognized the majority of the remaining revenue (with deferral of some immaterial remaining obligations until 2004 when the obligations were finalized).

In October 2003, IVAX Corporation agreed to assume exclusive rights to 3M’s branded health care respiratory products, together with related marketing and sales personnel, in nine European countries. The agreement covered QVAR™ (beclomethasone dipropionate HFA) Inhalation Aerosol, a “maintenance” medication used to prevent asthma attacks, and also covered Airomir™ (albuterol sulfate) Inhaler, a “rescue” medication used to relieve acute asthma symptoms. 3M will continue to manufacture and supply these products to IVAX. The total consideration due under the agreement, including minimum annual royalty payments, was $77 million, of which $26 million was paid in 2003 and $24 million was paid in 2004. 3M expects to receive $24 million in 2005 and $3 million in 2006. 3M may also receive additional royalty payments (up to a maximum of approximately $7 million in total) if IVAX achieves certain annual sales levels. The Company recognizes the royalty revenue related to the IVAX agreement ratably over the term of the licensing arrangement.

In 2003, local-currency growth and total sales growth in the Health Care segment were broad-based. Geographic area local-currency growth was led by the Asia Pacific area and the Latin America and Canada area, with the United States and Europe showing moderate growth. Operating income improvement was also broad-based. In 2003, the combined benefit from both the Eli Lilly agreement and the IVAX Corporation agreement was partially offset by separation costs in Health Care, resulting in a net benefit to operating income of approximately $20 million.

Industrial Business (17.2% of consolidated sales):

	2004			2003			2002
Sales (millions)	$	3,444		$	3,070		$	2,943
Sales change analysis:
Local currency (volume and price)	8.2		%	(0.7		)%	(3.2		)%
Translation	4.0			5.0			(0.2		)
Total sales change	12.2		%	4.3		%	(3.4		)%

Operating income (millions)	$	610		$	425		$	478
Percent change	43.7		%	(11.1		)%	2.9		%
Percent of sales	17.7		%	13.8		%	16.2		%

The Industrial segment serves a broad range of industrial markets, from appliance and electronics to paper and packaging and food and beverage. Products include tapes, a wide variety of coated and non-woven abrasives, adhesives, specialty materials and supply chain execution software solutions.

Industrial local-currency sales growth of 8.2% for the year was broad-based across major geographic areas and Industrial businesses. Acquisitions increased sales by 1.4%, driven by the February 2004 acquisition of HighJump Software, Inc., a provider of supply chain execution software. Strong local-currency sales growth helped leverage operating income growth. Operating income increased 43.7% to $610 million in 2004.

In 2003, industrial tape local-currency sales growth was offset by weakness in other industrial businesses. Geographic area local-currency growth was led by the Asia Pacific area, with the United States and Europe showing declines. Acquisitions increased sales by 1.6%. Driven by local-currency sales growth, industrial tape posted operating income growth, while employment reduction actions taken to improve competitiveness and lower the Industrial segment’s cost structure negatively impacted operating income.

Display and Graphics Business (17.1% of consolidated sales):

	2004			2003			2002
Sales (millions)	$	3,416		$	2,970		$	2,237
Sales change analysis:
Local currency (volume and price)	10.5		%	26.7		%	11.7		%
Translation	4.5			6.0			0.3
Total sales change	15.0		%	32.7		%	12.0		%

Operating income (millions)	$	1,133		$	886		$	535
Percent change	27.9		%	65.4		%	44.0		%
Percent of sales	33.2		%	29.8		%	23.9		%

The Display and Graphics segment serves markets that include electronic display, touch screen, traffic safety and commercial graphics. This segment includes optical film and lens solutions for electronic displays; touch screens and touch monitors; reflective sheeting for transportation safety; and commercial graphics systems. The optical business includes a number of different products that are protected by various patents and groups of patents. The remaining lifetimes of such patents range from one to greater than 15 years. These patents provide varying measures of exclusivity to 3M for a number of such products. 3M’s proprietary manufacturing technology and know-how also provide a competitive advantage to 3M independent of such patents.

Display and Graphics’ local-currency sales growth was 10.5% for 2004. Strong demand for 3M films that brighten the displays on electronic products, such as flat-panel computer monitors, cellular phones, notebook PCs and LCD televisions, continued to drive results in 2004. Year-on-year local-currency sales growth in the Optical Systems business was slower in the last half of 2004, primarily due to inventory channel adjustments in the LCD market. This resulted in reduced demand for 3M’s proprietary optical films and components. While this business is subject to periodic customer inventory fluctuations, 3M believes that this business will continue to be a significant growth engine for 3M. In the fourth quarter of 2004, 3M announced the phase out of its commercial videotape business, and this action, combined with a continuing decline in lens systems for the CRT rear-projection television market, negatively impacted sales and operating income. Operating income increased 27.9% to $1.133 billion in 2004.

The strong 2003 local-currency sales growth in the Display and Graphics segment was primarily due to optical systems growth, including the Corning Precision Lens acquisition that benefited sales by approximately 11%. Optical systems growth was led by sales of display enhancement films used in flat-panel devices. Geographic area local-currency sales growth was led by the Asia Pacific area and the Latin America and Canada area. Local-currency growth was moderate in the United States and Europe. Operating income increased 65.4% to $886 million in 2003, driven primarily by local-currency sales growth, production facilities running at high utilization levels and benefits from 3M’s corporate initiatives.

Consumer and Office Business (14.3% of consolidated sales):

	2004			2003			2002
Sales (millions)	$	2,861		$	2,607		$	2,444
Sales change analysis:
Local currency (volume and price)	6.9		%	2.6		%	(3.7		)%
Translation	2.8			4.1			0.5
Total sales change	9.7		%	6.7		%	(3.2		)%

Operating income (millions)	$	542		$	460		$	448
Percent change	17.9		%	2.5		%	9.3		%
Percent of sales	18.9		%	17.6		%	18.3		%

The Consumer and Office segment serves markets that include consumer retail, office retail, education, home improvement, building maintenance and other markets. Products in this segment include office supply products, stationery products, construction and home improvement/home care products, protective material products, and visual systems products.

In 2004, local-currency sales growth in Consumer and Office was 6.9%. Sales growth was fairly broad-based across the many retail channels 3M serves, most notably in mass-market consumer retail and home improvement. This included strong sales growth in construction and home improvement/home care products, office supply products and stationery products. Geographic area local-currency growth was led by the United States. Operating income increased 17.9% to $542 million in 2004.

2003 local-currency growth was led by the construction and home improvement, home care, and stationery products businesses, partially offset by lower local-currency sales in the visual systems business. Geographic area local-currency growth was moderate in all areas except Europe, which showed a decline. The modest increase in operating income resulted from strong gains in construction and home improvement and home care, partially offset by a decrease in visual systems operating income.

Safety, Security and Protection Services Business (10.6% of consolidated sales):

	2004			2003			2002
Sales (millions)	$	2,125		$	1,928		$	1,686
Sales change analysis:
Local currency (volume and price)	6.6		%	9.5		%	3.3		%
Translation	3.6			4.9			(0.5		)
Total sales change	10.2		%	14.4		%	2.8		%

Operating income (millions)	$	491		$	437		$	338
Percent change	12.3		%	29.1		%	11.9		%
Percent of sales	23.1		%	22.7		%	20.1		%

The Safety, Security and Protection Services segment serves a broad range of markets that strive to increase the safety, security and productivity of workers, facilities and systems. Major product offerings include personal protection products, safety and security products, energy control products, cleaning and protection products for commercial establishments, and roofing granules for asphalt shingles.

Safety, Security and Protection Services local-currency sales growth was 6.6% in 2004. Local-currency growth was driven by strong global demand for personal protective products and solutions, along with cleaning and protective products for commercial buildings. 3M’s acquisition of Hornell Holding AB, a European-based global supplier of personal safety equipment, added 2.3 percentage points of growth in 2004. Operating income increased 12.3% to $491 million in 2004.

2003 local-currency sales and operating income increases were primarily driven by the occupational health and environmental safety business, which experienced higher demand for respiratory masks, primarily resulting from concerns related to Severe Acute Respiratory Syndrome (SARS). Security systems, commercial care, building safety solutions, and industrial mineral products also posted local-currency growth and operating income improvements. All geographic areas showed local-currency growth, with growth strongest in the Asia Pacific and Latin America and Canada areas.

Electro and Communications Business (11.1% of consolidated sales):

	2004			2003			2002
Sales (millions)	$	2,224		$	2,101		$	2,034
Sales change analysis:
Local currency (volume and price)	2.7		%	(0.7		)%	(8.7		)%
Translation	3.1			4.0			0.2
Total sales change	5.8		%	3.3		%	(8.5		)%

Operating income (millions)	$	342		$	288		$	262
Percent change	18.8		%	9.7		%	26.2		%
Percent of sales	15.4		%	13.7		%	12.9		%

The Electro and Communications segment serves the electrical, electronics and communications industries, including electrical utilities; electrical construction, maintenance and repair; OEM electrical and electronics; computers and peripherals; consumer electronics; telecommunications central office, outside plant and enterprise; as well as aerospace, military, automotive and medical markets; with products that enable the efficient transmission of electrical power and speed the delivery of information and ideas. Products include electronic and interconnect solutions, microinterconnect systems, high-performance fluids, high-temperature and display tapes, telecommunications products and electrical products.

Local-currency sales in Electro and Communications increased 2.7% for 2004, led by electronic materials, along with electrical products for insulating, testing and sensing. Sales in the electronic solutions and telecommunications segments were negatively impacted by the general slowdown in the semiconductor industry and continued softness in the hard-line infrastructure segment of the telecommunications market. Geographically, local-currency growth in this business for 2004 was led by the Latin America and Canada area along with the Asia Pacific area. Operating income was up 18.8% to $342 million in 2004.

The decrease in local-currency sales in 2003 resulted from continued weakness in the global telecommunications industry. Local-currency sales in 3M’s telecom business were down over 10% from 2002. Geographic area local-currency growth was good in the Latin America and Canada area and the Asia Pacific area, but both the United States and Europe experienced local-currency declines. Despite a difficult economic and market environment, benefits from 3M’s corporate initiatives and productivity actions helped this business slightly improve its 2003 operating income. Driven by local-currency sales growth, electronic materials posted operating income growth. Operating income in 2003 was negatively impacted by $26 million due to additional employee reductions and actions to provide better alignment with the market environment while maintaining focus on key customers.

Transportation Business (8.4% of consolidated sales):

	2004			2003			2002
Sales (millions)	$	1,674		$	1,531		$	1,380
Sales change analysis:
Local currency (volume and price)	5.1		%	5.4		%	5.8		%
Translation	4.2			5.6			(0.2		)
Total sales change	9.3		%	11.0		%	5.6		%

Operating income (millions)	$	426		$	388		$	331
Percent change	9.8		%	17.2		%	22.8		%
Percent of sales	25.5		%	25.4		%	24.0		%

The Transportation segment serves markets that include automotive, automotive aftermarket, marine, aerospace and specialty vehicle markets. This segment provides components and products that are used in the manufacture, repair and maintenance of automotive, marine, aircraft and specialty vehicles.

In Transportation, local-currency sales growth was 5.1% in 2004. Top-line growth in this business continues to benefit from new products and solutions for customers, along with a strategy of replicating successful 3M solutions across several distinct segments of the transportation industry. Operating income increased 9.8% to $426 million in 2004.

In 2003, the automotive OEM and automotive aftermarket businesses led local-currency sales and operating income growth. The aerospace and aircraft maintenance business also posted local-currency sales and operating income growth. All geographic areas showed local-currency sales growth, led by the Asia Pacific and Latin America and Canada areas.

PERFORMANCE BY GEOGRAPHIC AREA

Financial information related to 3M operations in various geographic areas is provided in Note 17 to the Consolidated Financial Statements. A summary of key information and discussion related to 3M’s geographic areas follows:

Geographic Area Net Sales and Operating Income (Dollars in millions)	2004						2004 vs. 2003 % Change
	Sales		% of Total		Oper. Income		Local Currency		Translation		Total Sales Change		Oper. Income
United States	$	7,878	39.4	%	$	1,200	3.9	%	—		3.9	%	(1.0%	)
Europe, Middle East and Africa	5,183		25.9	%	1,014		0.8	%	9.0	%	9.8	%	25.4	%
Asia Pacific	5,168		25.8	%	1,874		13.6	%	5.6	%	19.2	%	36.4	%
Latin America and Canada	1,731		8.6	%	483		9.5	%	1.8	%	11.3	%	13.1	%
Other Unallocated	51		0.3	%	7
Total Company	$	20,011	100.0	%	$	4,578	6.0	%	3.8	%	9.8	%	23.3	%

While 3M manages its businesses globally and believes its business segment results are the most relevant measure of performance, the Company also utilizes geographic area data as a secondary performance measure. Export sales are reported within the geographic area where the final sales to 3M customers are made. A portion of the products or components sold by 3M’s operations to its customers are exported by these customers to different geographic areas. Thus, net sales in a particular geography may not be indicative of end-user consumption in that geography.

U.S. 2004 sales growth was led by the Consumer and Office; Safety, Security and Protection Services; and the Industrial businesses. U.S. operating income was down 1%, as higher year-on-year pension expense impacted operating income by 12%. European local-currency sales increased 0.8%, with growth in Safety, Security and Protection Services; Transportation; Industrial; and Health Care. Favorable exchange rates, coupled with ongoing productivity efforts, boosted operating income in Europe by 25.4% to approximately $1 billion. Local-currency sales growth in the Asia Pacific area was 13.6%, with all seven business segments posting positive local-currency sales growth. 3M posted 4.3% local-currency sales gains in Japan, despite a fairly sluggish economic picture in the second half of 2004. Growth in the rest of the Asia Pacific area was 20.7%, led by China, Korea and Taiwan. In the combined Latin America and Canada area, six of seven businesses had local-currency sales increases, led by Electro and

Communications; Transportation; Health Care; Industrial; and Consumer and Office. For 2004, international operations represented 60.6% of 3M’s sales.

Employment:

Employment was virtually unchanged from year-end 2003. Since March 31, 2001, employment has declined by nearly 10,600 people, with 6,900 of the decline related to the 2001/2002 corporate restructuring plan, and additional declines due to the integration of acquisitions, additional employment reduction actions and attrition. The Corning Precision Lens, Inc. acquisition in the fourth quarter of 2002 added approximately 1,500 employees. The Company continues to increase headcount in faster-growing areas of the world, such as Asia Pacific, primarily to support increasing local sales. Sales per employee in local currencies increased approximately 7% in 2004, 8.5% in 2003 and approximately 9% in 2002.

Capital Spending/Net Property, Plant and Equipment:

The bulk of 3M capital spending historically has been in the United States, resulting in higher net property, plant and equipment balances in the U.S. The Company is striving to more closely align its manufacturing and sourcing with geographic market sales, and because approximately 60% of sales are outside the United States, this would increase production outside the United States, helping to improve customer service and reduce working capital requirements. For 2005, the Company expects to spend approximately $950 million on purchases of property, plant and equipment.

CRITICAL ACCOUNTING ESTIMATES

Information regarding significant accounting policies is included in Note 1 to the Consolidated Financial Statements. As stated in Note 1, the preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

The Company believes its most critical accounting estimates relate to legal proceedings, the Company’s pension and postretirement obligations, and potential asset impairment issues. Senior management has discussed the development, selection and disclosure of its critical accounting estimates with the Audit Committee of 3M’s Board of Directors.

Legal Proceedings:

Please refer to the section entitled “Accrued Liabilities and Insurance Receivables Related to Legal Proceedings” (contained in Part I, Item 3, Legal Proceedings, of this Annual Report on Form 10-K) for a description of the process the Company follows for the accrual and disclosure of loss contingencies, the categories of claims for which the Company has been able to estimate its probable liability and for the estimate of its related insurance receivables, and factors affecting such estimates.

Pension and Postretirement Obligations:

3M has various company-sponsored retirement plans covering substantially all U.S. employees and many employees outside the United States. The Company accounts for its defined benefit pension plans in accordance with SFAS No. 87, “Employers’ Accounting for Pensions”, which requires that amounts recognized in financial statements be determined on an actuarial basis. Pension benefits associated with these plans are generally based primarily on each participant’s years of service, compensation, and age at retirement or termination. See Note 11

to the Consolidated Financial Statements for additional discussion of actuarial assumptions used in determining pension liability and expense.

As previously disclosed in the Company’s June 30, 2004 and September 30, 2004 Form 10-Qs, in 2004, the Company’s U.S. plan measurement date was changed from September 30 to December 31. The primary reasons for this change include consistency between the U.S. and international dates, the increased clarity that results from having the same measurement and balance sheet dates, and administrative simplification. This change did not have a material impact on the determination of periodic pension cost or pension obligations.

A significant element in determining the Company’s pension expense in accordance with SFAS No. 87 is the expected return on plan assets, which is based on projected results for similar allocations among asset classes. The difference between the expected return and the actual return on plan assets is deferred and, under certain circumstances, amortized over future years of service. Therefore, the net deferral of past asset gains (losses) ultimately affects future pension expense. For the U.S. pension plan, the Company’s assumption for the expected return on plan assets was 9.00% for 2004. Refer to Note 11 to the Consolidated Financial Statements for information on how this rate is determined. The Company is lowering the 2005 expected return on plan assets by 0.25 percentage points to 8.75%.

The discount rate used to measure pension plan liabilities reflects the current rate at which the pension liabilities could be effectively settled as of December 31, 2004. In estimating this rate, the Company looks at rates of return on fixed-income investments of similar duration to the liabilities in the plan that receive high, investment grade ratings by recognized ratings agencies. By applying this methodology, the Company determined a discount rate of 5.75% to be appropriate as of December 31, 2004, which is a reduction of 0.25 percentage points from the rate used as of September 30, 2003.

For the year ended December 31, 2004, the change in the minimum pension liability within accumulated other comprehensive income increased stockholders’ equity by $1.193 billion (after-tax). This increase was primarily the result of the assets being above the Accumulated Benefit Obligation for the U.S. qualified plan, which caused the minimum pension liability recorded for the years ended December 31, 2003 and 2002 to be reversed. As a result, the Company’s U.S. qualified plan recorded a Prepaid Pension Asset of $1.851 billion.

For the year ended December 31, 2004, the Company recognized total consolidated pre-tax pension expense (after settlements, curtailments and special termination benefits) of $325 million, up from $168 million in 2003. Pension expense (before settlements, curtailments and special termination benefits) is anticipated to increase to approximately $342 million in 2005. As previously mentioned, the Company lowered the expected return on assets assumption from 9.00% in 2004 to 8.75% in 2005. For the U.S. pension plans, holding all other factors constant, an increase/decrease in the expected long-term rate of return on plan assets by 0.25 percentage points would decrease/increase U.S. pension expense by approximately $19 million in 2005. For the U.S. pension plans, holding all other factors constant, an increase/decrease in the discount rate used to measure plan liabilities by 0.25 percentage points would decrease/increase U.S. pension expense by approximately $30 million in 2005.

Potential Asset Impairment Issues:

3M net property, plant and equipment totaled approximately $5.7 billion at December 31, 2004. Management makes estimates and assumptions in preparing the consolidated financial statements for which actual results will emerge over long periods of time. This includes the recoverability of long-lived assets employed in the business, including assets of acquired businesses. These estimates and assumptions are closely monitored by management and periodically adjusted as circumstances warrant. For instance, expected asset lives may be shortened or an impairment recorded based on a change in the expected use of the asset or performance of the related business reporting unit. In addition, 3M goodwill totaled approximately $2.7 billion at December 31, 2004, which, based on impairment testing, is not impaired. A portion of this goodwill (approximately $300 million) is in 3M’s telecommunications business, which competes in a very uncertain industry. While the Company believes this business will maintain its value, events such as a significant adverse change in the business climate, could create future impairment losses.

NEW ACCOUNTING PRONOUNCEMENTS

In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004), “Share-Based Payment”. SFAS No. 123R supersedes APB Opinion No. 25, which requires recognition of an expense when goods or services are provided. SFAS No. 123R requires the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense over the period in which the share-based compensation vests. The Company is required to adopt the

provisions of SFAS No. 123R effective July 1, 2005. Additional information regarding this and other accounting pronouncements is included in Note 1 to the Consolidated Financial Statements.

FINANCIAL CONDITION AND LIQUIDITY

The Company generates significant ongoing cash flow as evidenced by the reduction in net debt during 2004 as follows:

At December 31 (Millions)	2004		2003		2002

Total Debt	$	2,821	$	2,937	$	3,377
Less: Cash & Cash Equiv.	2,757		1,836		618
Net Debt	$	64	$	1,101	$	2,759

3M believes its ongoing cash flows provide ample cash to fund expected investments and capital expenditures. The Company has an AA credit rating from Standard & Poor’s and an Aa1 credit rating from Moody’s Investors Service. The Company has sufficient access to capital markets to meet currently anticipated growth and acquisition investment funding needs. The Company does not utilize derivative instruments linked to the Company’s stock.

The Company’s financial condition and liquidity at December 31, 2004, remained 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 $2.649 billion at December 31, 2004, compared with $2.638 billion at December 31, 2003. This slight increase was primarily related to an increase in cash ($921 million) offset by an increase in debt classified as short-term borrowings and current portion of long-term debt ($892 million). The cash balance benefited from higher net income and working capital improvements in accounts receivable, inventory and accounts payable.

The Company uses various working capital measures that place emphasis and focus on certain working capital assets and liabilities (i.e. accounts receivable, inventory, accounts payable). These measures may not be computed the same as similarly titled measures used by other companies. The accounts receivable turnover index (defined as quarterly net sales – fourth quarter at year-end – multiplied by four, divided by ending net accounts receivable) totaled 7.29 at December 31, 2004, an improvement from 6.95 at December 31, 2003. Receivables increased $78 million compared with December 31, 2003, with currency translation of $120 million (due to the weaker U.S. dollar) driving this increase. The inventory turnover index (defined as quarterly factory cost – fourth quarter at year-end – multiplied by four, divided by ending inventory) was 5.29 at December 31, 2004, an improvement from 5.12 at December 31, 2003. Inventories increased $81 million compared with December 31, 2003, with currency translation of $80 million accounting for almost all of this increase. Another working capital measure used by the Company also reflects the impact of accounts payable. This combined index (defined as quarterly net sales – fourth quarter at year-end – multiplied by four, divided by ending net accounts receivable plus inventory less accounts payable) was 5.78 at December 31, 2004, an improvement from 5.48 at December 31, 2003. Accounts payable increased $81 million compared to December 31, 2003.

Cash Flows from Operating Activities:

Years ended December 31 (Millions)	2004			2003			2002
Net income	$	2,990		$	2,403		$	1,974
Depreciation and amortization	999			964			954
Company pension contributions	(591		)	(749		)	(1,086		)
Company pension expense	325			168			141
Income taxes (deferred and accrued income taxes)	396			539			568
Accounts receivable	56			38			145
Inventories	7			281			279

Other — net	65			67			(121		)
Net cash provided by operating activities	$	4,282		$	3,773		$	2,992

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 both 2004 and 2003, cash flow improvements were primarily driven by higher net income, tax timing differences and certain working capital improvements (i.e. accounts receivables, inventories, accounts payable). In all periods presented, significant Company pension contributions negatively impacted cash flows. In all years, with larger amounts in 2003 and 2002, a portion of the tax timing benefit relates to the tax benefit received from Company pension contributions. In 2003, 3M made $46 million of payments under the corporate restructuring plan, compared with $306 million in 2002.

In the quarter ended September 30, 2004, the Company made a special pension contribution to 3M’s Japanese pension plan of $155 million and a discretionary contribution of $300 million to its U.S. qualified pension plan. In the third quarter of 2003, 3M made a discretionary contribution of $600 million to its U.S. qualified pension plan, compared with a discretionary contribution of $789 million in the third quarter of 2002. Future contributions will 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.

The following table recaps for breast implant and respirator masks/asbestos litigation the liabilities and associated insurance receivables, cash received from insurance, cash fees and payments made, and the pre-tax expense for 2004 and 2003. Because of the time delay between payment of claims and receipt of insurance reimbursements, the December 31, 2004, amounts for both breast implant and respirator mask/asbestos liabilities are less than expected insurance recoveries. Thus, the expected net inflow of cash will increase future cash flows. The Company recorded the LePage’s verdict liability of $93 million pre-tax in the first quarter of 2003. For a more detailed discussion of these and other legal proceedings, refer to Part I, Item 3, Legal Proceedings, of this Annual Report on Form 10-K.

Investments in property, plant and equipment are enabling growth in diverse markets, helping to meet product demand and increasing manufacturing efficiency. In the first three months of 2004, 3M entered into two business combination agreements. 3M acquired HighJump Software, Inc., a U.S. company that provides supply chain execution software and solutions, with annual sales of approximately $36 million. 3M initially purchased 91 percent of the outstanding shares of Hornell Holding AB and subsequently acquired all of the remaining outstanding shares. Hornell Holding AB is a global supplier of personal protective equipment for welding applications, with annual sales of approximately $50 million. In August 2004, 3M acquired 100% of the outstanding shares of Info-X Inc., a U.S. company that provides coding compliance software and data for health care organizations, with annual sales of approximately $10 million. Refer to Note 2 to the Consolidated Financial Statements for additional information on these 2004 business combinations and for information concerning 2003 and 2002 business combinations. The Company is actively considering additional acquisitions.

Proceeds from the sale of investments in 2003 include $26 million of cash received related to the sale of 3M’s 50% ownership in Durel Corporation to Rogers Corporation. Purchases of investments totaled $10 million in 2004, $16 million in 2003 and $7 million in 2002. These purchases include additional survivor benefit insurance and equity investments.

Total debt at December 31, 2004, was $2.821 billion, down from $2.937 billion at year-end 2003, due to the strong cash flow generated during 2004. In 2004, the cash flow increase in net short-term debt of $399 million includes the portion of short-term debt with original maturities of 90 days or less. The repayment of debt of $868 million primarily related to commercial paper retirements of approximately $475 million and the retirements of $350 million in medium-term notes. Proceeds from debt of $358 million primarily related to commercial paper issuances. Total debt was 21% of total capital (total capital is defined as debt plus equity), compared with 27% at year-end 2003.

Debt securities, including the Company’s shelf registration, its medium-term notes program, dealer remarketable securities and Convertible Note are all discussed in more detail in Note 9 to the Consolidated Financial Statements. 3M has a shelf registration and medium-term notes program through which $1.5 billion of medium-term notes may be offered. In 2004, the Company issued approximately $62 million in debt securities under its medium-term notes program. The medium-term notes program and shelf registration have remaining capacity of approximately $1.438 billion. The Company’s $350 million of dealer remarketable securities (classified as current portion of long-term debt) were remarketed for one year in December 2004. In addition, the Company has a Convertible Note with a book value of $556 million at December 31, 2004. At December 31, 2004, the dealer remarketable securities, Convertible Note and $62 million of medium-term notes are classified as current portion of long-term debt as the result of put provisions associated with these debt instruments. However, the Company does not anticipate redemption of these securities in 2005. For a discussion of accounting pronouncements that will affect accounting treatment for the Convertible Note, refer to Note 1 to the Consolidated Financial Statements for discussion of EITF Issue No. 04-08, “The Effect of Contingently Convertible Debt on Diluted Earnings per Share” and proposed SFAS No. 128R, “Earnings per Share”.

Repurchases of common stock are made to support the Company’s stock-based employee compensation plans and for other corporate purposes. On November 10, 2003, the Board of Directors authorized the purchase of up to $1.5 billion of the Company’s common stock between January 1, 2004 and December 31, 2004. In November 2004, 3M’s Board of Directors authorized the repurchase of an additional $200 million of the Company’s common stock in 2004 and also authorized the repurchase of up to $2.0 billion of the Company’s common stock between January 1, 2005 and January 31, 2006. Refer to the table captioned “Issuer Purchases of Equity Securities” in Part II, Item 5, for more information.

Cash dividends paid to stockholders totaled $1.125 billion ($1.44 per share) in 2004, $1.034 billion ($1.32 per share) in 2003 and $968 million ($1.24 per share) in 2002. 3M has paid dividends since 1916. In February 2005, the Board of Directors increased the quarterly dividend on 3M common stock to 42 cents per share, equivalent to an annual dividend of $1.68 per share. This marks the 47th consecutive year of dividend increases.

Other cash flows from financing activities include distributions to minority interests, changes in cash overdraft balances, and principal payments for capital leases.

Liquidity:

The Company’s liquidity remains strong. Primary short-term liquidity needs are provided through U.S. commercial paper and euro commercial paper issuances. As of December 31, 2004, outstanding total commercial paper issued totaled $671 million and averaged approximately $387 million during 2004. Medium-term note shelf borrowing capacity totaled $1.438 billion as of December 31, 2004. Credit support for outstanding commercial paper is provided by a $565 million, 364-day credit agreement among a group of primary relationship banks. This facility provides up to $115 million in letters of credit ($86 million of which was utilized at December 31, 2004). In 2005, it is anticipated that the 364-day credit agreement will be replaced by a five-year agreement with terms substantially the same as that of the current agreement. Committed credit facilities of $53 million are in place across several international subsidiary locations. The Company also has uncommitted lines of credit outside the United States totaling $637 million.

The Company believes it is unlikely that its access to the commercial paper market will be restricted. Cash and cash equivalents and certain other current assets could provide additional liquidity to meet near term obligations, if necessary. At year-end 2004, certain debt agreements ($350 million of dealer remarketable securities and $202 million of ESOP debt) had ratings triggers (BBB-/Baa3 or lower) that would require repayment of debt. The Company currently has AA/Aa1 debt ratings. In addition, the $565 million, 364-day credit agreement requires 3M to maintain a capitalization ratio at no more than 0.60 to 1 at the end of each quarter. This ratio is calculated as funded debt (including all borrowed money and letters of credit utilized) to the sum of funded debt and equity. At December 31, 2004, this ratio was approximately 0.22 to 1.

3M’s cash balance at December 31, 2004 totaled $2.757 billion. 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 paid dividends of more than $1.1 billion in 2004, and has a long history of dividend increases. 3M’s Board of Directors authorized the purchase of up to $2.0 billion of the Company’s common stock between January 1, 2005 and January 31, 2006. The Company may also make additional contributions to its pension plan in the future, but exact amounts are uncertain and will depend on market conditions.

Off-Balance Sheet Arrangements and Contractual Obligations:

As of December 31, 2004, the Company had not utilized special purpose entities to facilitate off-balance sheet financing arrangements. 3M’s accrued product warranty liabilities, recorded on the Consolidated Balance Sheet as part of current and long-term liabilities, are estimated at approximately $22 million. 3M does not consider this amount to be material. The fair value of 3M guarantees of loans with third parties and other guarantee arrangements are not material.

In addition to guarantees, 3M, in the normal course of business, periodically enters into agreements that require 3M to indemnify either major customers or suppliers for specific risks, such as claims for injury or property damage arising out of 3M products or the negligence of 3M personnel, or claims alleging that 3M products infringe third party patents or other intellectual property. While 3M’s maximum exposure under these indemnification provisions cannot be estimated, these indemnifications are not expected to have a material impact on the Company’s consolidated financial position or results of operations.

A summary of the Company’s significant contractual obligations as of December 31, 2004, follows:

Contractual Obligations (Millions)	Payments due by year
Contractual Obligations (Millions)	Total		2005		2006		2007		2008		2009		After 2009
Long-term debt (including current portion)	$	2,132	$	1,405	$	39	$	40	$	42	$	44	$	562
Operating leases	340		93		56		39		19		15		118
Capital leases	106		5		5		4		5		5		82
Unconditional purchase obligations	368		154		70		46		17		11		70
Total contractual cash obligations	$	2,946	$	1,657	$	170	$	129	$	83	$	75	$	832

Long-term debt payments due in 2005 include $350 million of dealer remarketable securities (final maturity 2010), $62 million of medium-term notes (final maturity 2044), and $556 million of convertible notes (final maturity 2032). These securities are classified as current portion of long-term debt as the result of put provisions associated with these debt instruments.

Unconditional purchase obligations are defined as an agreement to purchase goods or services that is enforceable and legally binding on the Company. Included in the unconditional purchase obligations category above are certain obligations related to take or pay contracts, capital commitments, service agreements and utilities. These estimates include both unconditional purchase obligations with terms in excess of one year and normal ongoing purchase obligations with terms of less than one year. Many of these commitments relate to take or pay contracts, in which 3M guarantees payment to ensure availability of products or services that are sold to customers. The Company expects to receive consideration (products or services) for these unconditional purchase obligations. The purchase obligation amounts do not represent the entire anticipated purchases in the future, but represent only those items for which the Company is contractually obligated. The majority of 3M’s products and services are purchased as needed, with no unconditional commitment. For this reason, these numbers will not provide a reliable indicator of the Company’s expected future cash outflows on a stand-alone basis.

As discussed in Note 11 to the Consolidated Financial Statements, the Company does not have a required minimum pension contribution obligation for its U.S. plans in 2005. Thus, Company contributions to its U.S. and international pension plans are expected to be largely discretionary in 2005 and future years. Contractual capital commitments are also included in the preceding table, but these commitments represent a small part of the Company’s expected capital spending in 2005 and beyond. For 2005, the Company expects to spend approximately $950 million on purchases of property, plant and equipment.

FINANCIAL INSTRUMENTS

The Company enters into contractual derivative arrangements in the ordinary course of business to manage foreign currency exposure, interest rate risks and commodity price risks. A financial risk management committee, composed of senior management, provides oversight for risk management and derivative activities. This committee determines the Company’s financial risk policies and objectives, and provides guidelines for derivative instrument utilization. This committee also establishes procedures for control and valuation, risk analysis, counterparty credit approval, and ongoing monitoring and reporting.

The Company enters into foreign exchange forward contracts, options and swaps to hedge against the effect of exchange rate fluctuations on cash flows denominated in foreign currencies and certain intercompany financing transactions. The Company manages interest rate risks 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 Company manages commodity price risks through negotiated supply contracts, price protection swaps and forward physical contracts.

A variance/co-variance statistical modeling technique was used to test the Company’s exposure to changes in currency and interest rates and assess the risk of loss in after-tax earnings of financial instruments, derivatives and underlying exposures outstanding at December 31, 2004. The model (third-party bank dataset) used a 95% confidence level over a 12-month time horizon. Based on this analysis of the Company’s interest rate risks, possible changes in interest rates would not have a material adverse effect on after-tax earnings ($5 million at December 31, 2004 and $6 million at December 31, 2003). Based on this analysis of the primary foreign exchange risks, possible changes in foreign exchange rates could adversely impact after-tax earnings by $61 million ($67 million at December 31, 2003). When including certain commodity risks, possible changes in commodity rates could adversely impact after-tax earnings by an additional $10 million (an additional $3 million at December 31, 2003). The model used analyzed over 20 different currencies and five commodities, but does not purport to represent what actually will be experienced by the Company. This model does not include certain hedge transactions, because the Company believes their inclusion would not materially impact the results.

The Company is striving to more closely align its manufacturing and sourcing with geographic market sales, and because approximately 60% of sales are outside the United States, this would increase production outside the United States. This will also help mitigate the effects from currency fluctuations. In 2001, the Company increased the amount and duration of its foreign currency hedges to help lessen year-over-year impacts and to improve the predictability of future earnings. However, this hedging program will not make 3M immune to currency impacts.

The global exposures related to purchased components and materials are such that a one percent price change would result in a pre-tax cost or savings of approximately $44 million per year. The global energy exposure is such that a 10% price change would result in a pre-tax cost or savings of approximately $30 million per year. Derivative instruments are used to hedge less than one percent of the purchased components and materials exposure and are used to hedge approximately 10% of this energy exposure.

FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7, contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements may be identified by the use of words like “plan,” “expect,” “aim,” “believe,” “project,” “anticipate,” “intend,” “estimate,” “will,” “should,” “could” and similar expressions in connection with any discussion, expectation or projection of future operating or financial performance, events or trends. In particular, these include statements about the Company’s strategy for growth, product development, market position, future performance or results of current or anticipated products, interest rates, foreign exchange rates, and the outcome of contingencies, such as legal proceedings.

Factors That Could Affect Future Results – Forward-looking statements are based on certain assumptions and expectations of future events that are subject to risks and uncertainties. Actual future results and trends may differ materially from historical results or those projected in any such forward-looking statements depending on a variety of factors, including, but not limited to, the following:

* Results and trends are impacted by the effects of, and changes in, worldwide economic conditions. The Company operates in more than 60 countries and derives approximately 60% of its revenues from outside the United States. The Company’s business may be affected by factors in the United States and other countries that are beyond its control, such as downturns in economic activity in a specific country or region; social, political or labor conditions in a specific country or region; or potential adverse foreign tax consequences.

* Foreign currency exchange rates and fluctuations in those rates may affect the Company’s ability to realize projected growth rates in its sales and net earnings and its results of operations. Because the Company derives approximately 60% of its revenues from outside the United States, its ability to realize projected growth rates in sales and net 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 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; gain market acceptance of new products; or successfully complete clinical trials and obtain regulatory approvals. For example, new 3M pharmaceutical products, like any pharmaceutical under development, face substantial risks and uncertainties in the process of development and regulatory review. 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 and materials, including oil-derived compounds, due to market demand, currency exchange risks, material shortages and other factors. The Company depends on various components and materials supplied by others for the manufacturing of its products and it is possible that any of its supplier relationships could be interrupted or 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 due to market demand, currency risks or material shortages, or that future price fluctuations will not have a material adverse effect on the Company.

* There is the possibility that acquisitions and strategic alliances may not meet sales and/or profit expectations. As part of the Company’s strategy for growth, the Company has made and may continue to make acquisitions and enter into strategic alliances. However, there can be no assurance that the Company will be able to quickly integrate the acquired business and obtain the anticipated synergies or that acquisitions and strategic alliances will be beneficial to the Company.

* The Company’s future results may be affected if the Company generates less operating income from its corporate initiatives than estimated. 3M’s corporate initiatives include Six Sigma, Global Sourcing Effectiveness, 3M Acceleration, eProductivity and Global Business Processes. Cost reduction projects related to these initiatives are expected to contribute an additional $400 million to operating income in 2005. There can be no assurance that all of the estimated operating income improvements from the initiatives 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, significant settlement 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. A specific factor that may influence the Company’s estimate of its future asbestos-related liabilities is the pending Congressional consideration of legislation to reform asbestos-related litigation and pertinent information derived from that process. For a more detailed discussion of the legal proceedings involving the Company and associated accounting estimates, see the discussion of “Legal Proceedings” in Part I, Item 3 of this document.

Management’s Responsibility for Financial Reporting

Management is responsible for the integrity and objectivity of the financial information included in this report. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. Where necessary, the financial statements reflect estimates based on management judgment.

Management has established and maintains a system of internal accounting and other controls for the Company and its subsidiaries. This system and its established accounting procedures and related controls are designed to provide reasonable assurance that assets are safeguarded, that the books and records properly reflect all transactions, that policies and procedures are implemented by qualified personnel, and that published financial statements are properly prepared and fairly presented. The Company’s system of internal control is supported by widely communicated written policies, including business conduct policies, which are designed to require all employees to maintain high ethical standards in the conduct of Company affairs. Internal auditors continually review the accounting and control system.

3M Company

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. Management conducted an assessment of the Company’s internal control over financial reporting based on the framework established by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control – Integrated Framework. Based on the assessment, management concluded that, as of December 31, 2004, the Company’s internal control over financial reporting is effective.

Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2004 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.

3M Company

Report of Independent Registered Public Accounting Firm

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

We have completed an integrated audit of 3M Company’s 2004 consolidated financial statements and of its internal control over financial reporting as of December 31, 2004 and audits of its 2003 and 2002 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of 3M Company and its subsidiaries (the Company) at December 31, 2004 and 2003, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2004 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Internal control over financial reporting

Also, in our opinion, management’s assessment, included in the accompanying Management’s Report on Internal Control Over Financial Reporting, that the Company maintained effective internal control over financial reporting as of December 31, 2004 based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control – Integrated Framework issued by the COSO. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements

NOTE 1. Significant Accounting Policies

Consolidation: 3M is a diversified global manufacturer, technology innovator and marketer of a wide variety of products. All significant subsidiaries are consolidated. All significant intercompany transactions are eliminated. As used herein, the term “3M” or “Company” refers to 3M Company and subsidiaries unless the context indicates otherwise.

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 year-end exchange rates. Income and expense items are translated at average rates of exchange prevailing during the year. Cumulative translation adjustments are recorded as a component of accumulated other comprehensive income in stockholders’ equity.

Reclassifications: Certain prior period balance sheet amounts have been reclassified to conform with the current year presentation.

Use of estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Cash and cash equivalents: Cash and cash equivalents consist of cash and temporary investments with maturities of three months or less when purchased.

Investments: Investments primarily include the cash surrender value of life insurance policies, real estate not used in the business, venture capital and equity-method investments. Unrealized gains and losses relating to investments classified as available-for-sale are recorded as a component of accumulated other comprehensive income (loss) in stockholders’ equity.

Inventories: Inventories are stated at lower of cost or market, with cost generally determined on a first-in, first-out basis.

Property, plant and equipment: Property, plant and equipment, including capitalized interest and internal engineering costs, are recorded at cost. Depreciation of property, plant and equipment generally is computed using the straight-line method based on the estimated useful lives of the assets. The estimated useful lives of buildings and improvements primarily range from 10 to 40 years, with the majority in the range of 20 to 40 years. Machinery and equipment estimated useful lives primarily range from three to 15 years, with the majority in the range of five to 10 years. Fully depreciated assets are retained in property and accumulated depreciation accounts until disposal. Upon disposal, assets and related accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposal, is charged or credited to operations. Property, plant and equipment amounts are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset (asset group) may not be recoverable. An impairment loss would be recognized when the carrying amount of an asset exceeds the estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. The amount of the impairment loss to be recorded is calculated by the excess of the asset’s carrying value over its fair value. Fair value is generally determined using a discounted cash flow analysis.

Goodwill: Goodwill is the excess of cost of an acquired entity over the amounts assigned to assets acquired and liabilities assumed in a business combination. Goodwill is not amortized. Goodwill is tested for impairment annually, and will be tested for impairment between annual tests if an event occurs or circumstances change that would indicate the carrying amount may be impaired. Impairment testing for goodwill is done at a reporting unit level. Reporting units are one level below the business segment level, but can be combined when reporting units within the same segment have similar economic characteristics. 3M has 18 reporting units at December 31, 2004. The majority of goodwill relates to and is assigned directly to a specific reporting unit. An impairment loss generally would be recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit. The estimated fair value of a reporting unit is determined using earnings for the reporting unit multiplied by a price/earnings ratio for comparable industry groups, or by using a discounted cash flow analysis. The Company completed its assessment of any potential impairment upon adoption of this standard and performs annual assessments. The Company completed its annual goodwill impairment test in the fourth quarter of 2004 and determined that no goodwill was impaired.

Intangible assets: Intangible assets include patents, tradenames and other intangible assets acquired from an independent party. Intangible assets with an indefinite life, namely certain tradenames, are not amortized. Intangible assets with a definite life are amortized on a straight-line basis, with estimated useful lives ranging from two to 20 years. Indefinite-lived intangible assets are tested for impairment annually, and will be tested for impairment between annual tests if an event occurs or circumstances change that would indicate that the carrying amount may be impaired. Intangible assets with a definite life are tested for impairment whenever events or circumstances indicate that a carrying amount of an asset (asset group) may not be recoverable. The Company has determined that no material impairments existed as of December 31, 2004. An impairment loss is recognized when the carrying amount of an asset exceeds the estimated undiscounted cash flows used in determining the fair value of the asset. The amount of the impairment loss to be recorded is calculated by the excess of the asset’s carrying value over its fair value. Fair value is generally determined using a discounted cash flow analysis. Costs related to internally developed intangible assets are expensed as incurred.

Revenue (sales) recognition: The Company sells a wide range of products to a diversified base of customers around the world and has no material concentration of credit risk. Revenue is recognized when the risks and rewards of ownership have substantively transferred to customers. This condition normally is met when the product has been delivered or upon performance of services. The Company records estimated reductions to revenue for customer and distributor incentives, such as rebates, at the time of the initial sale.

The majority of 3M’s sales agreements are for standard products and services with customer acceptance occurring upon delivery of the product or performance of the service. 3M also enters into agreements that contain multiple-elements (such as equipment, installation and service) or non-standard terms and conditions. For multiple-element arrangements, 3M recognizes revenue for delivered elements when the delivered item has stand-alone value to the customer, fair values of undelivered elements are known, customer acceptance has occurred, and there are only customary refund or return rights related to the delivered elements. In addition to the preceding conditions, equipment revenue is not recorded until the installation has been completed if equipment acceptance is dependent upon installation, or if installation is essential to the functionality of the equipment. Installation revenues are not recorded until installation has been completed. For prepaid service contracts, sales revenue is recognized on a straight-line basis over the term of the contract, unless historical evidence indicates the costs are incurred on other than a straight-line basis. License fee revenue is recognized as earned, with no revenue recognized until the inception of the license term. On occasion, agreements will contain milestones, or 3M will recognize revenue based on proportional performance. For these agreements, and depending on the specifics, 3M may recognize revenue upon completion of a substantive milestone, or in proportion to costs incurred.

Accounts Receivable and Allowances: Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The Company maintains allowances for bad debts, cash discounts, product returns and various other adjustments. The allowance for doubtful accounts and product returns is based on the best estimate of the amount of probable credit losses in existing accounts receivable and anticipated sales returns. The Company determines the allowances based on historical write-off experience by industry and regional economic data and historical sales returns. The Company reviews the allowance for doubtful accounts monthly. The Company does not have any off-balance-sheet credit exposure related to its customers.

Advertising and merchandising: These costs are charged to operations in the year incurred, and totaled $433 million in 2004, $405 million in 2003 and $372 million in 2002.

Research, development and related expenses: These costs are charged to operations in the year incurred and are shown on a separate line of the Consolidated Statement of Income. Research and development expenses, covering basic scientific research and the application of scientific advances to the development of new and improved products and their uses, totaled $759 million in 2004, $749 million in 2003 and $738 million in 2002. Related expenses primarily include technical support provided to customers for existing products by 3M laboratories.

Internal-use software: The Company capitalizes direct costs of materials and services used in the development of internal-use software. Amounts capitalized are amortized on a straight-line basis over a period of three to five years and are reported as a component of machinery and equipment within property, plant and equipment.

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

Income taxes: 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 reliability exists. As of December 31, 2004, no valuation allowances were recorded.

Earnings per share: The difference in the weighted average shares outstanding for calculating basic and diluted earnings per share is attributable to the dilution associated with the Company’s stock-based compensation plans. Certain Management Stock Ownership Program average options outstanding during the years 2004, 2003 and 2002 were not included in the computation of diluted earnings per share because they would not have had a dilutive effect (6.6 million average options for 2004, 6.4 million average options for 2003 and 11.0 million average options for 2002). As discussed in Note 9 to the Consolidated Financial Statements, the conditions for conversion related to the Company’s $639 million in aggregate face amount of Convertible Notes have never been met; accordingly, there was no impact on 3M’s diluted earnings per share. 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. The computations for basic and diluted earnings per share for the years ended December 31 follow:

Earnings Per Share Computations (Amounts in millions, except per share amounts)	2004		2003		2002
Numerator:
Net income	$	2,990	$	2,403	$	1,974
Denominator:
Denominator for weighted average common shares outstanding – basic	780.5		782.8		780.0
Dilution associated with the Company’s stock-based compensation plans	16.0		12.5		11.0

Earnings per share – basic	$	3.83	$	3.07	$	2.53
Earnings per share – diluted	3.75		3.02		2.50

Stock-based compensation: The intrinsic value method is used as prescribed by Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees”, and generally no compensation cost is recognized for either the General Employees’ Stock Purchase Plan (GESPP) or the Management Stock Ownership Program (MSOP). The GESPP is considered non-compensatory. In December 2002, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 148, “Accounting for Stock-Based Compensation – Transition and Disclosure – an amendment of SFAS No. 123.” The Company has adopted the disclosure requirements of SFAS No. 148. Refer to Notes 14 and 15 for additional information concerning the GESPP and MSOP and also refer to additional discussion later in Note 1 concerning the impact of SFAS No. 123R. Pro forma amounts based on the options’ estimated Black-Scholes fair value, net of tax, at the grant dates for awards under the Company’s stock-based compensation plans for the years ended December 31 are as follows:

Stock-Based Compensation Pro Forma Net Income and Earnings Per Share (Millions, except per share amounts)	2004			2003			2002
Net income, as reported	$	2,990		$	2,403		$	1,974

Pro forma	3.56			2.88			2.32

Comprehensive income: Total comprehensive income and the components of accumulated other comprehensive income (loss) are presented in the Consolidated Statement of Changes in Stockholders’ Equity and Comprehensive Income. Accumulated other comprehensive income (loss) is composed of foreign currency translation effects (including hedges of net investments in international companies), minimum pension liability adjustments, unrealized gains and losses on available-for-sale debt and equity securities, and unrealized gains and losses on cash flow hedging instruments.

Derivatives and hedging activities: All derivative instruments are recorded on the balance sheet at fair value. The Company uses interest rate swaps, currency swaps, and forward and option contracts to manage risks generally associated with foreign exchange rate, interest rate and commodity market volatility. All hedging instruments are designated and effective as hedges, in accordance with U.S. generally accepted accounting principles. If the underlying hedged transaction ceases to exist, all changes in fair value of the related derivatives that have not been settled are recognized in current earnings. Instruments that do not qualify for hedge accounting are marked to market with changes recognized in current earnings. The Company does not hold or issue derivative financial instruments for trading purposes and is not a party to leveraged derivatives.

New Accounting Pronouncements

In January 2003, the FASB issued and subsequently revised FASB Interpretation No. 46 (FIN 46), “Consolidation of Variable Interest Entities.” This interpretation addresses the requirements for business enterprises to consolidate related entities in which they are determined to be the primary economic beneficiary as a result of their variable economic interests. The interpretation provides guidance in evaluating multiple economic interests in an entity and in determining the primary beneficiary. Effective January 1, 2004, the Company adopted FIN 46. The Company reviewed its major commercial relationships and its overall economic interests with other companies, consisting of related parties, contracted manufacturing vendors, companies in which it has an equity position, and other suppliers to determine the extent of its variable economic interests in these parties. As a result of this review, 3M identified several immaterial manufacturing-supplier arrangements that had certain variable interest entity characteristics. 3M has concluded that it is not the primary beneficiary in any of these relationships and, therefore, has not consolidated any of these entities. 3M does not have any material exposure to these entities that would require disclosure. The adoption of this standard did not impact 3M’s consolidated results of operations or financial condition.

On December 8, 2003, the Medicare Prescription Drug Improvement and Modernization Act of 2003 (the Medicare Act) was signed into law. Refer to Note 11 to the Consolidated Financial Statements for discussion of the Medicare Act.

In September 2004, the FASB’s Emerging Issues Task Force finalized EITF Issue No. 04-08, “The Effect of Contingently Convertible Debt on Diluted Earnings per Share” that would require the dilutive effect of shares from contingently convertible debt to be included in the diluted earnings per share calculation regardless of whether the contingency has been met. The Company has $639 million in aggregate face amount of 30-year zero coupon senior notes that are convertible into approximately 6 million shares of common stock if certain conditions are met. These conditions have never been met. The FASB is also in the process of amending SFAS No. 128, anticipated to be issued in 2005, which is expected to further address this and several other issues. Unless the Company takes steps to modify certain terms of this debt security, EITF Issue No. 04-08 and proposed SFAS No. 128R (when effective), would result in an increase of approximately 6 million shares to diluted shares outstanding to give effect to the contingent issuance of shares. Also, using the if-converted method, net income for the diluted earnings per share calculations would be adjusted for interest expense associated with this debt instrument. EITF Issue No. 04-08 would have been effective beginning with the Company’s 2004 fourth quarter. However, due to the FASB’s delay in issuing SFAS No. 128R and the Company’s intent and ability to settle this debt security in cash versus the issuance of stock, the impact of the additional diluted shares will not be included in the diluted earnings per share calculation until SFAS No. 128R is effective. Prior periods’ diluted shares outstanding and diluted earnings per share amounts will be restated to present comparable information when SFAS No. 128R is effective. The estimated annual reduction in 3M’s diluted earnings per share would have been approximately $.02 per share for total year 2004. Because the impact of this standard is ongoing, 3M’s diluted shares outstanding and diluted earnings per share amounts would be impacted until retirement or modification of certain terms of this debt security.

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs – An Amendment of ARB No. 43, Chapter 4”. SFAS No. 151 amends the guidance in Accounting Research Bulletin (ARB) No. 43, Chapter 4, “Inventory Pricing,” to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Among other provisions, the new rule requires that items such as idle facility expense, excessive spoilage, double freight, and rehandling costs be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal” as stated in ARB No. 43. Additionally, SFAS No. 151 requires that the allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. SFAS No. 151 is effective for fiscal years beginning after June 15, 2005, and is required to be adopted by the Company effective January 1, 2006. The Company does not expect SFAS No. 151 to have a material impact on 3M’s consolidated results of operations or financial condition.

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets – An Amendment of APB Opinion No. 29”. SFAS No. 153 eliminates the exception from fair value measurement for nonmonetary exchanges of similar productive assets in paragraph 21(b) of APB Opinion No. 29, “Accounting for Nonmonetary Transactions,” and replaces it with an exception for exchanges that do not have commercial substance. SFAS No 153 specifies that a nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. SFAS No. 153 is effective for the fiscal periods beginning after June 15, 2005, and is required to be adopted by the Company effective January 1, 2006. The Company does not expect SFAS No. 153 to have a material impact on 3M’s consolidated results of operations or financial condition.

In December 2004, the FASB issued SFAS No. 123 (revised 2004), “Share-Based Payment”. SFAS No. 123R supersedes APB Opinion No. 25, which requires recognition of an expense when goods or services are provided. SFAS No. 123R requires the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense over the period in which the share-based compensation vests. SFAS No. 123R permits a prospective or two modified versions of retrospective application under which financial statements for prior periods are adjusted on a basis consistent with the pro forma disclosures required for those periods by the original SFAS No. 123. The Company is required to adopt the provisions of SFAS No. 123R effective July 1, 2005, at which time the Company will begin recognizing an expense for unvested share-based compensation that has been issued or will be issued after that date. Under the retroactive options, prior periods may be restated either as of the beginning of the year of adoption, January 1, 2005 for the Company, or for all periods presented. The Company has not yet finalized its decision concerning the transition option it will utilize to adopt SFAS No. 123R. The Company’s Management Stock Ownership Program (MSOP) is a three-year plan that requires shareholder approval at the May 2005 Annual Shareholder Meeting. The Company is considering various changes that will be detailed in the Company’s Definitive Proxy Statement, but will not be finalized until approval has been granted by the Company’s shareholders. The Company does expect the impact of the adoption of SFAS No. 123R to be material, but due to potential changes in the MSOP, future share-based compensation amounts may differ from the pro forma amounts disclosed earlier in Note 1 to the Consolidated Financial Statements.

In December 2004, the FASB issued FASB Staff Position (FSP) No. 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004”, which provides guidance under SFAS No. 109, “Accounting for Income Taxes,” with respect to recording the potential impact of the repatriation provisions of the American Jobs Creation Act of 2004 (the Jobs Act) on enterprises’ income tax expense and deferred tax liability. The Jobs Act was enacted on October 22, 2004. The Jobs Act creates a temporary incentive for U.S. corporations to repatriate accumulated income earned abroad by providing an 85% dividends received deduction for certain dividends from controlled foreign corporations. FSP No. 109-2 states that an enterprise is allowed time beyond the financial reporting period of enactment to evaluate the effect of the Jobs Act on its plan for reinvestment or repatriation of foreign earnings for purposes of applying SFAS No. 109. The deduction is subject to a number of limitations and uncertainty remains as to how to interpret certain provisions in the Act. As such, the Company is not yet in a position to decide whether, and to what extent, the Company might repatriate foreign earnings that have not yet been remitted to the U.S. and, as provided for in FSP No. 109-2, the Company has not adjusted its tax expense or deferred tax liability to reflect the repatriation provisions of the Jobs Act. Based on the Company’s analysis to date, however, it is possible that the Company will repatriate an amount totaling between $800 million and $950 million, with the respective tax liability ranging from $40 million to $50 million. The Company expects to be in a position to finalize its assessment after issuance of further regulatory guidance and passage of statutory technical corrections.

NOTE 2. Acquisitions and Divestitures

Year 2004 acquisitions:

In February 2004, 3M (Industrial Business) purchased 100 percent of the outstanding common shares of HighJump Software, Inc., a U.S. company that provides supply chain execution software and solutions. The total purchase price of approximately $66 million included $23 million of cash paid (net of cash acquired) plus 541,581 shares of 3M common stock. The 3M common stock had a market value of $43 million at the acquisition measurement date and was previously held as 3M treasury stock.

In March 2004, 3M (Safety, Security and Protection Services Business) purchased 91 percent of the outstanding shares of Hornell Holding AB, a Swedish company, for approximately $95 million, including assumption of debt. This $95 million includes $57 million of cash paid (net of cash acquired) and the acquisition of $38 million of debt, most of which has been repaid. Subsequently, 3M acquired all of the remaining outstanding shares for approximately $6 million in cash. Hornell Holding AB is a global supplier of personal protective equipment for welding applications.

In August 2004, 3M (Health Care Business) purchased 100 percent of the outstanding shares of Info-X Inc., a U.S. company, for $17 million in cash (net of cash acquired). The acquired company provides coding compliance software and data for health care organizations.

Purchased identifiable intangible assets for these acquisitions are being amortized on a straight-line basis over lives ranging from two to 20 years (weighted-average life of 11 years). Research and development charges from these acquisitions totaled $1 million. Pro forma information related to these acquisitions is not included because the impact of these acquisitions, either individually or in the aggregate, on the Company’s consolidated results of operations is not considered to be material.

In September 2004, 3M and Corning Incorporated reached a settlement related to issues associated with 3M’s 2002 acquisition of Corning Precision Lens, Inc. (now called Precision Optics, Inc.). In September 2004, 3M received $30 million from Corning related to this settlement.

The purchase price allocations and the resulting impact on the Consolidated Balance Sheet relating to all 2004 acquisitions follow:

Year 2003 acquisitions:

In January 2003, 3M purchased an additional 25% interest in Sumitomo 3M Limited from NEC Corporation for $377 million in cash. Prior to this purchase, 3M controlled and owned 50% of Sumitomo 3M Limited and fully consolidated both Sumitomo 3M Limited’s balance sheet and results of operations, with a provision for the minority interest that did not have participating rights. As a result of this acquisition, 3M now owns 75% of Sumitomo 3M Limited. Sumitomo Electric Industries, Ltd., a Japanese corporation, owns the remaining 25% of Sumitomo 3M Limited. Because all business segments benefit from this combination, goodwill acquired in this acquisition was allocated to 3M’s seven business segments.

During the first quarter of 2003, 3M (Display and Graphics Business) finalized the purchase of Corning Precision Lens, Inc. (Precision Optics, Inc.), which was acquired in December 2002, exclusive of the settlement described previously under “Year 2004 acquisitions”. The impacts of finalizing the purchase price allocation, including a working capital adjustment and payment of direct acquisition expenses, are shown in the business combination activity table that follows.

During the year ended December 31, 2003, 3M entered into six additional business combinations for a total purchase price of $49 million, net of cash acquired.

1) 3M (Industrial Business) purchased 100% of the outstanding shares of Solvay Fluoropolymers, Inc. (SFI), previously a wholly owned subsidiary of Solvay America, Inc. SFI is a manufacturer of fluoroplastic products.

2) 3M (Display and Graphics Business) purchased Corning Shanghai Logistics Company Limited, previously a wholly owned subsidiary of Corning Incorporated. This business is involved in the distribution of lens systems for projection televisions.

3) 3M (Safety, Security and Protection Services Business) purchased 100% of the outstanding shares of GuardiaNet Systems, Inc., a software company.

4) 3M (Electro and Communications Business) purchased the outstanding minority interest of Pouyet Communications, Inc. (PCI), an Indian company. PCI is a telecommunications supplier.

5) 3M (Health Care Business) purchased 100% of the outstanding shares of Vantage Health Limited, a British company. Vantage Health Limited develops health information systems software.

6) 3M (Health Care Business) purchased certain tangible and intangible assets from AstraZeneca S.p.A., an Italian company. AstraZeneca S.p.A. is a research-based pharmaceuticals company.

The business combination activity for the year ended December 31, 2003, is summarized in the following table. Purchased identifiable intangible assets of $12 million are being amortized on a straight-line basis over lives ranging from 5 to 15 years (weighted-average life of 11.3 years). There were no in-process research and development charges associated with these acquisitions. Pro forma information related to these acquisitions is not included because the impact of these acquisitions, either individually or in the aggregate, on the Company’s consolidated results of operations is not considered to be material.

Year 2002 acquisitions:

In December 2002, 3M purchased 100% of the outstanding common shares of Corning Precision Lens, Inc., a wholly owned subsidiary of Corning Incorporated, for $850 million in cash. Corning Precision Lens, Inc. has become a wholly owned subsidiary of 3M, operating under the name 3M Precision Optics, Inc. The acquired company is a manufacturer of lens systems for projection televisions, which will broaden 3M’s technology position in the global display industry. The purchase agreement between 3M and Corning Incorporated contained a contingency. This contingency was based on the final working capital valuation of the assets purchased and liabilities assumed as of the acquisition date. This contingency was not booked in 3M’s balance sheet as of December 31, 2002, because the final amount of the asset or liability was not known. This contingency was resolved in 2003 and is described previously under “Year 2003 acquisitions”.

In December 2002, 3M purchased the 43% minority ownership of 3M Inter-Unitek GmbH. 3M paid $304 million in cash to the minority interest shareholders of 3M Inter-Unitek GmbH. 3M Inter-Unitek GmbH is the parent company of 3M ESPE Dental AG.

During the year ended December 31, 2002, 3M completed seven additional business combinations for a total purchase price of $139 million, which was paid with $104 million in cash, net of cash acquired, and $35 million of 3M common stock (555,584 common shares, split-adjusted). A summary of these seven business combinations follows:

1) 3M (Industrial Business) purchased certain assets and specified liabilities of Emtech Emulsion Technologies, Inc. and Emtech Manufacturing Corporation. These companies are involved in the manufacture and sale of durable film label materials.

2) 3M (Industrial Business) purchased certain assets and specified liabilities of Polymer Manufacturing, Inc. This company, based in Oxnard, California, is a manufacturer of two-part polyurethane adhesives, plastic repair materials, sealants and related accessories.

3) 3M (Safety, Security and Protection Services Business) purchased the shares of AiT Corporation. AiT Corporation, based in Ottawa, Ontario, Canada, is a manufacturer of travel ID security systems.

4) 3M (Health Care Business) purchased the shares of Ruffing IT. This company, based in Germany, develops quality assurance software for medical records.

5) 3M (Health Care Business) purchased from GlaxoSmithKline the right to manufacture and distribute the Migril product line in certain African nations. Migril is an over-the-counter treatment for migraine headaches.

6) 3M (Industrial Business) purchased an 80% interest in certain assets of Shanghai Grinding Wheel Works, a Chinese company. These assets are being used to manufacture and sell coated abrasive products.

7) 3M (Electro and Communications Business) purchased an additional 6% of Quante AG (a telecommunications supplier).

The business combination activity for the year ended December 31, 2002, is summarized in the following table. Purchased identifiable intangible assets of $45 million are being amortized on a straight-line basis over lives ranging from two to 17 years (weighted-average life of 10.6 years). There were no in-process research and development charges associated with these acquisitions. Pro forma information related to these acquisitions is not included because the impact of these acquisitions, either individually or in the aggregate, on the Company’s consolidated results of operations is not considered to be material.

NOTE 3. Goodwill and Intangible Assets

As discussed in Note 16, 3M realigned its business segments and began reporting under this new structure effective January 1, 2005. To reflect this new structure, the December 31, 2004 and 2003 goodwill balances presented below include goodwill reclassifications from the Industrial segment to the Electro and Communications segment. The reclassifications were performed using a relative fair value approach. The business segment realignment also resulted in certain changes in reporting units for 3M. The Company determined that this change in reporting units resulted in no goodwill impairment. 3M has 18 reporting units under the criteria set forth by SFAS No. 142. SFAS No. 142 requires that goodwill be tested for impairment at least annually and when reporting units are changed. The Company completed its annual goodwill impairment test in the fourth quarter of 2004 and determined that no goodwill was impaired.

Purchased goodwill from acquisitions totaled $141 million in 2004, none of which is deductible for tax purposes. Goodwill was reduced by $13 million as a result of the Corning Incorporated settlement. The increase in the goodwill balance in 2004 primarily relates to the 2004 business combinations previously discussed and changes in foreign currency exchange rates during the period. The goodwill balance by business segment follows:

Goodwill (Millions)	Dec. 31, 2003 balance		2004 Acquisition activity			2004 Translation and other			Dec. 31, 2004 balance
Health Care	$	513	$	17		$	45		$	575

NOTE 4. 2001/2002 Corporate Restructuring Program

During the first half of 2001, the Company developed and announced a restructuring plan that consolidated certain operations and streamlined the organization to increase speed and productivity. In June 2001, the Company completed the identification of the significant actions to be taken and obtained approvals from the appropriate level of management. In the fourth quarter of 2001, the Company obtained approvals for certain additional actions. These actions were substantially completed by June 30, 2002.

During 2001, 3M incurred $569 million of pre-tax expenses principally related to the restructuring plan. The 2001 charges related to employee severance and benefits ($472 million), accelerated depreciation ($80 million) and other ($17 million). In the first six months of 2002, 3M incurred $202 million of pre-tax expense relating to the restructuring plan. The 2002 charges related to employee severance and benefits ($111 million), accelerated depreciation ($47 million) and other ($44 million).

The severance charges were taken in the quarter when management approved the plans and after severance benefits had been communicated to the employees. The accelerated depreciation (incremental charges resulting from shortened depreciable lives, primarily related to downsizing or consolidating manufacturing operations) related to assets included in property, plant and equipment. Estimated salvage values were based on estimates of proceeds upon sale of certain affected assets. The charges related to other exit activities included incremental costs and contractual obligations for items such as lease termination payments and other facility exit costs (such as demolition of buildings, inventory disposals, other) incurred as a direct result of this plan.

In connection with its restructuring plan, the Company eliminated a total of about 6,900 positions. These positions represented a wide range of functions throughout the Company. Of the 6,900 employment reductions, about 45% occurred in the United States, 30% in Europe and the balance in other international areas. All business segments were impacted directly and also indirectly through reduced allocations of corporate staff service costs. In order to enhance segment comparability and reflect management’s focus on ongoing operations, these restructuring costs were recorded in Corporate and Unallocated, not in the individual business segments.

Special termination pension and medical benefits, aggregating $43 million in 2002 and $62 million in 2001, were offered to eligible employees. Certain pension and medical benefits will generally be paid over their life expectancies. The Company also recorded $3 million of non-cash stock option expense in 2002 ($8 million in 2001) due to the reclassification of certain employees age 50 and older to retiree status, resulting in a modification of their original stock option awards for accounting purposes. The current liabilities and a portion of the non-current liabilities were funded through cash provided by operations, while funding for certain long-term special termination pension and medical liabilities are provided through established pension and postretirement trust funds. The majority of the long-term portion of the liability, primarily special termination pension and medical liabilities, is reflected as a component of 3M’s pension and medical trust plans as a portion of the Accumulated Benefit Obligation (ABO). It is estimated that 3M’s benefit plans reflect approximately $24 million of restructuring-related long-term liabilities that had not yet been paid out by the trusts as of December 31, 2004. This amount is reduced gradually over time as the trust funds make payments.

The restructuring plan included actions in 25 locations in the United States, 27 in Europe, eight in the Asia Pacific area, 13 in Latin America and four in Canada. The Company did not discontinue any major product lines as a result of the restructuring plan. The restructuring charges did not include any write-down of goodwill or other intangible assets.

NOTE 6. Supplemental Stockholders’ Equity and Comprehensive Income Information

Common stock ($.01 par value per share) of 3.0 billion shares is authorized, with 944,033,056 shares issued. During the third quarter of 2003, $4 million was transferred within stockholders’ equity from “Capital in excess of par value” to “Common stock” in connection with the two-for-one split of the Company’s common stock. Treasury stock is reported at cost, with 170,514,775 shares at December 31, 2004, 159,915,696 shares at December 31, 2003, and 163,641,694 shares at December 31, 2002. Preferred stock, without par value, of 10 million shares is authorized but unissued.

The components of the ending balances of accumulated other comprehensive income (loss) as of December 31 follow:

Accumulated Other Comprehensive Income (Loss) (Millions)	2004			2003			2002
Cumulative translation – net	$	282		$	(208	)	$	(858	)
Minimum pension liability adjustments – net	(110		)	(1,303		)	(1,130		)
Debt and equity securities, unrealized gain – net	2			2			1
Cash flow hedging instruments, unrealized gain (loss) – net	(42		)	(45		)	(39		)
Total accumulated other comprehensive income (loss)	$	132		$	(1,554	)	$	(2,026	)

The minimum pension liability adjustment is calculated on an annual basis. If the accumulated benefit obligation (ABO) exceeds the fair value of pension assets, the employer must recognize a liability that is at least equal to the unfunded ABO. For the year ended December 31, 2004, the change in the minimum pension liability within accumulated other comprehensive income increased stockholders’ equity by $1.193 billion (after-tax). This increase was primarily the result of the assets being above the Accumulated Benefit Obligation for the U.S. qualified plan, which caused the minimum pension liability recorded for the years ended December 31, 2003 and 2002 to be reversed. In the fourth quarter of 2003, 3M recorded a minimum pension liability adjustment within other comprehensive income of $173 million (net of tax), compared with $1.056 billion (net of tax) in the fourth quarter of 2002.

Income tax effects for cumulative translation are not significant because no tax provision has been made for the translation of foreign currency financial statements into U.S. dollars. Reclassification adjustments are made to avoid double counting in comprehensive income items that are also recorded as part of net income. A summary of these reclassification adjustments follows:

Reclassification Adjustments to Comprehensive Income (Millions)	2004			2003			2002
Gains on sale of equity securities, net of tax provision of $1 million for 2004 and $2 million for 2002	$	2		$	—		$	3

Individual amounts on the Consolidated Statement of Cash Flows exclude the effects of acquisitions, divestitures and exchange rate impacts, which are presented separately.

In 2004, 3M purchased 100 percent of the outstanding common shares of HighJump Software, Inc., for approximately $66 million, which included $23 million of cash paid (net of cash acquired) plus 3M common stock that had a fair market value of $43 million. Dividends declared, but not paid at December 31, 2004, of $34 million were payable to minority interests in consolidated subsidiaries. In 2003, capital lease obligations of approximately $70 million were incurred, primarily related to a lease for a building in the United Kingdom (refer to Note 12 to the Consolidated Financial Statements for more information on capital leases). In 2002, 3M purchased certain assets and specified liabilities of Emtech Emulsion Technologies, Inc. and Emtech Manufacturing Corporation in exchange for shares of 3M common stock that had a fair market value of $35 million.

In the third quarter of 2004, the Company made a $300 million tax deductible contribution to its U.S. qualified pension plan compared with a $600 million tax deductible contribution in 2003 and a $789 million tax deductible contribution in 2002. The Company also made additional contributions to certain international pension plans in 2004, 2003 and 2002. The current income tax provision includes a benefit for the pension contributions; the deferred tax provision includes a cost for the related temporary difference. Also in 2004, the Company reversed a majority of the minimum pension liability, which was initially recorded in 2002. The change in the year-end deferred tax balance includes the effect of reversing this minimum pension liability in addition to the annual provision for deferred income tax expense.

Annual tax provisions include amounts considered sufficient to pay assessments that may result from examination of prior year tax returns; however, the amount ultimately paid upon resolution of issues may differ materially from the amount accrued.

As a result of certain employment commitments and capital investments made by 3M, income from manufacturing activities in certain countries is subject to reduced tax rates or, in some cases, is exempt from tax for years through 2012. The income tax benefits attributable to the tax status of these subsidiaries are estimated to be $32 million (4 cents per diluted share) in 2004, $34 million (4 cents per diluted share) in 2003 and $27 million (3 cents per diluted share) in 2002.

On October 22, 2004, the President signed the American Jobs Creation Act of 2004 (the “Jobs Act”). The Jobs Act provides a deduction for income from qualified domestic production activities, which will be phased in from 2005 through 2010. In return, the Act also provides for a two-year phase-out of the existing extra-territorial income exclusion (ETI) for foreign sales that was viewed to be inconsistent with international trade protocols by the European Union. Uncertainty remains as to how to interpret numerous provisions in the Jobs Act. At this time, the Company does not expect the net effect of the phase-out of the ETI and the phase-in of this new deduction to materially impact the effective tax rate for 2005 and 2006.

Under the guidance in FASB Staff Position No. FAS 109-1, Application of SFAS No. 109, “Accounting for Income Taxes,” to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004, the deduction will be treated as a “special deduction” as described in SFAS No. 109. As such, the special deduction has no effect on deferred tax assets and liabilities existing at the enactment date. Rather, the impact of this deduction will be reported in the period in which the deduction is claimed on the Company’s tax return.

In addition to the deduction for income from qualified domestic production activities, the Jobs Act also creates a temporary incentive for U.S. corporations to repatriate accumulated income earned abroad by providing an 85 percent dividends received deduction for certain dividends from controlled foreign corporations. The deduction is subject to a number of limitations and uncertainty remains as to how to interpret certain provisions in the Jobs Act. As such, the Company is not yet in a position to decide whether, and to what extent, it might repatriate foreign earnings that have not yet been remitted to the U.S. Based on the Company’s analysis to date, however, it is possible that the Company will repatriate an amount totaling between $800 million and $950 million, with the respective tax liability ranging from $40 million to $50 million. The Company expects to be in a position to finalize its assessment after issuance of further regulatory guidance and passage of statutory technical corrections.

As of December 31, 2004, approximately $5.6 billion of unremitted earnings attributable to international companies was considered to be indefinitely invested. The Company’s intention is to reinvest the indefinitely invested earnings permanently or to repatriate the earnings when it is tax effective to do so. It is not practicable to determine the amount of incremental taxes that might arise were these earnings to be remitted. However, the Company believes that U.S. foreign tax credits would largely eliminate any U.S. taxes and offset any foreign withholding taxes due on remittance. Provisions are made for estimated U.S. and foreign incomes taxes, less available tax credits and deductions, which may be incurred on the remittance of the Company’s share of subsidiaries’ undistributed earnings not deemed to be permanently reinvested. The Company is in the process of evaluating its position with respect to the indefinite investment of foreign earnings to take into account the possible election of the repatriation provisions contained in the Jobs Act. Therefore, the $5.6 billion of unremitted earnings noted above includes earnings that may be remitted as part of the Jobs Act. The status of the Company’s evaluation of these provisions is described above.

NOTE 9. Long-Term Debt and Short-Term Borrowings

Long-term debt and short-term borrowings as of December 31 consisted of the following (with interest rates as of December 31, 2004):

Maturities of long-term debt for the five years subsequent to December 31, 2004 are as follows (in millions):

2005		2006		2007		2008		2009		Thereafter		Total
$	1,405	$	39	$	40	$	42	$	44	$	562	$	2,132

The ESOP debt is serviced by dividends on stock held by the ESOP and by Company contributions. These contributions are not reported as interest expense, but are reported as an employee benefit expense in the Consolidated Statement of Income. Other borrowings includes debt held by 3M’s international companies and floating rate notes in the United States, with the long-term portion of this debt primarily comprised of U.S. dollar floating rate debt. At December 31, 2004, available short-term lines of credit globally totaled about $618 million, of which $88 million was utilized. The Company also has uncommitted lines of credit outside the United States totaling $637 million. Debt covenants do not restrict the payment of dividends.

In September 2003, the Company filed a shelf registration statement with the Securities and Exchange Commission relating to the potential offering of debt securities of up to $1.5 billion. This shelf registration became effective in October 2003. In December 2003, the Company established under the shelf a medium-term notes program through which up to $1.5 billion of medium-term notes may be offered. 3M plans to use the net proceeds from issuances of debt securities under this registration for general corporate purposes, including the repayment of debt; investments in or extensions of credit to 3M subsidiaries; or the financing of possible acquisitions or business expansion. At December 31, 2004, $62 million of medium-term notes had been issued under the medium-term notes program. The medium-term notes program and shelf registration have remaining capacity of approximately $1.438 billion.

On November 15, 2002, 3M sold $639 million in aggregate face amount of 30-year zero coupon senior notes (the “Convertible Notes”) that are convertible into shares of 3M common stock. The gross proceeds from the offering, to be used for general corporate purposes, were $550 million ($540 million net of issuance costs). The book value of the Convertible Notes at December 31, 2004, was $556 million. On February 14, 2003, 3M registered these Convertible Notes in a registration statement filed with the Securities and Exchange Commission. The terms of the Convertible Notes include a yield to maturity of .50% and an initial conversion premium of 40% over the $65.00 (split-adjusted) closing price of 3M common stock on November 14, 2002. If certain conditions for conversion (relating to the closing common stock prices of 3M exceeding the conversion trigger price for specified periods) are met, holders may convert each of the 30-year zero-coupon senior notes into 9.4602 shares of 3M common stock in any calendar quarter commencing after March 31, 2003. The conversion trigger price for the fourth quarter of 2004 was $119.40 per share. If the conditions for conversion are met, and 3M elects not to settle in cash, the 30-year zero-coupon senior notes will be convertible in the aggregate into approximately 6.0 million shares of 3M common stock. 3M may redeem the 30-year zero-coupon senior notes at any time in whole or in part, beginning November 21, 2007, at the greater of the accreted conversion price or the current market price. Holders of the 30-year zero-coupon senior notes have the option to require 3M to purchase their notes at accreted value on November 21 in the years 2005, 2007, 2012, 2017, 2022 and 2027. 3M may choose to pay the redemption purchase price in cash and/or common stock; however, if redemption occurs, the Company has the intent and ability to settle this debt security in cash. Debt issuance costs are amortized on a straight-line basis over a three-year period beginning in November 2002. The conditions for conversion have never been met; accordingly, there was no impact on 3M’s diluted earnings per share. For a discussion of accounting pronouncements that will affect accounting treatment for the Convertible Note, refer to Note 1 to the Consolidated Financial Statements for discussion of EITF Issue No. 04-08, “The Effect of Contingently Convertible Debt on Diluted Earnings per Share” and proposed SFAS No. 128R, “Earnings per Share”.

In December 2000, the Company issued $350 million of dealer remarketable debt securities, which are classified as current portion of long-term debt. The remarketable securities can be remarketed annually, at the option of the dealer, for a year each time, with a final maturity date of December 2010. In December 2004, the Company’s dealer remarketable securities were remarketed for one year. They were reissued with a fixed coupon rate of 5.67%.

NOTE 10. Derivatives and Other Financial Instruments

The Company uses interest rate swaps, currency swaps, and forward and option contracts to manage risks generally associated with foreign exchange rate, interest rate and commodity market volatility. The information that follows explains the various types of derivatives and financial instruments, and includes a table that recaps net investment hedging and cash flow hedging amounts.

Foreign Currency Forward and Option Contracts: The Company enters into foreign exchange forward contracts, options and swaps 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. At December 31, 2004, the Company had various open foreign exchange forward and option contracts, the majority of which had maturities of one year or less. The amounts at risk are not material because the Company has the ability to generate offsetting foreign currency cash flows. The settlement or extension of these derivatives will result in reclassifications to earnings in the period during which the hedged transactions affect earnings (from other comprehensive income). The maximum length of time over which 3M is hedging its exposure to the variability in future cash flows for a majority of the forecasted transactions, excluding those forecasted transactions related to the payment of variable interest on existing financial instruments, is 12 months. During the second quarter of 2002, the Company converted a foreign-currency based pricing contract into a dollar-based pricing contract. This resulted in the discontinuance of certain foreign currency cash flow hedges. The Company recognized a $10 million pre-tax loss (recorded in cost of sales) related to the discontinuance of these contracts in 2002. Hedge ineffectiveness was not material for the years 2004, 2003 and 2002.

Interest Rate and Currency 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 Company uses interest rate and currency swaps to manage interest rate risk related to borrowings.

At December 31, 2004, the Company had interest rate swaps with a fair value of $3 million ($21 million at December 31, 2003) designated as fair value hedges of underlying fixed rate obligations. 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 on the underlying debt instrument that is also recorded in interest expense. All existing fair value hedges are 100% effective and, thus, there is no impact on earnings due to hedge ineffectiveness.

As circumstances warrant, the Company also uses cross-currency interest rate swaps to hedge foreign currency and interest rates. As part of this strategy, in September 2003, the Company entered into a three-year combined interest rate and currency swap with a notional amount of $300 million. This transaction is a partial hedge of 3M’s net investment in 3M’s Japanese subsidiaries. This swap converts a variable rate U.S. dollar exposure to a variable rate yen-denominated exposure.

Net Investment Hedging: As circumstances warrant, the Company uses foreign currency debt and forwards to hedge portions of the Company’s net investments in foreign operations. For hedges that meet the effectiveness requirements, the net gains or losses are recorded in cumulative translation within other comprehensive income, with any ineffectiveness recorded in cost of sales. Hedge ineffectiveness was not material in 2004, 2003 and 2002.

Commodity Price Management: The Company manages commodity price risks through negotiated supply contracts, price protection swaps and forward physical contracts. The Company uses commodity price swaps 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 (typically 100% effective), and reclassified into cost of sales in the period during which the hedged transaction affects earnings. 3M has hedged its exposure to the variability of future cash flows for certain forecasted transactions through 2005. No significant commodity cash flow hedges were discontinued during the years 2004, 2003 and 2002.

Net Investment Hedging and Cash Flow Hedging: Amounts recorded in cumulative translation related to net investment hedging, and cash flow hedging instrument disclosures follow. Reclassification adjustments are made to avoid double counting in comprehensive income items that are also included as part of net income. The amount of the reclassification adjustment recognized in other comprehensive income is equal to, but opposite in sign from, the amount of the realized gain or loss in net income.

* Based on exchange rates at December 31, 2004, the Company expects to reclassify to earnings over the next 12 months a majority of the cash flow hedging instruments after-tax loss of $42 million (with the impact largely offset by foreign currency cash flows from underlying hedged items).

Currency Effects: 3M estimates that year-on-year currency effects, including hedging impacts, increased net income by $181 million in 2004 and $73 million in 2003, and reduced net income by $35 million in 2002. 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 increased net income by $48 million in 2004, benefiting from lower year-on-year hedging losses. 3M estimates that year-on-year derivative and other transaction gains and losses decreased net income by $73 million in 2003 and $25 million in 2002.

Credit risk: The Company is exposed to credit loss in the event of nonperformance by counterparties in interest rate swaps, currency swaps, and option and foreign exchange 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.

Fair value of financial instruments: At December 31, 2004 and 2003, the Company’s financial instruments included cash and cash equivalents, accounts receivable, 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 (except the $350 million dealer remarketable security and Convertible Note) approximated carrying values because of the short-term nature of these instruments. Available-for-sale investments and derivative contracts are reported at fair values. Fair values for investments held at cost are not readily available, but are estimated to approximate fair value.

NOTE 11. Pension and Postretirement Benefit Plans

3M has various company-sponsored retirement plans covering substantially all U.S. employees and many employees outside the United States. Pension benefits associated with these plans are generally based on each participant’s years of service, compensation, and age at retirement or termination. In addition to providing pension benefits, the Company provides certain postretirement health care and life insurance benefits for substantially all of its U.S. employees who reach retirement age while employed by the Company. Most international employees and retirees are covered by government health care programs. The cost of company-provided postretirement health care plans for international employees is not material and is combined with U.S. amounts.

On December 8, 2003, the Medicare Prescription Drug Improvement and Modernization Act of 2003 (the Medicare Act) was signed into law. The Act expands Medicare to include coverage for prescription drugs. 3M sponsors medical programs, including prescription drug coverage for U.S. retirees. On May 19, 2004, the FASB issued FSP No. 106-2, “Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003”, which requires current recognition of the federal subsidy that employers may receive for providing drug coverage to retirees. FSP No. 106-2 was effective for the Company July 1, 2004. The Company remeasured its plans’ assets and accumulated postretirement benefit obligation (APBO) as of June 30, 2004 to include the effects of the Medicare Act. The Medicare Act reduced the APBO by $240 million, which was partially offset by an increase to the APBO of $170 million as a result of the plan remeasurement. The net impact to the APBO was a reduction of $70 million. The remeasurement, including the impact of the Medicare Act, reduced expense by $8 million for the second half of 2004.

The Company’s pension funding policy is to deposit with independent trustees amounts allowable by law. Trust funds and deposits with insurance companies are maintained to provide pension benefits to plan participants and their beneficiaries. There are no plan assets in the non-qualified plan due to its nature. For its U.S. postretirement plan, the Company has set aside amounts at least equal to annual benefit payments with an independent trustee.

As previously disclosed in the Company’s June 30, 2004 and September 30, 2004 Form 10-Qs, in 2004, the Company’s U.S. plan measurement date was changed from September 30 to December 31. Information presented in the tables for U.S. plans for 2004 reflects a measurement date of December 31, 2004 and September 30 for 2003 and 2002. The primary reasons for this change include consistency between the U.S. and international dates, the increased clarity that results from having the same measurement and balance sheet dates, and administrative simplification. This change did not have a material impact on the determination of periodic pension cost or pension obligations.

Following is a summary of the funded status of the plans as of the plan measurement dates:

(Millions)	Qualified and Non-qualified Pension Benefits
	United States						International
	2004			2003			2004			2003

Plan assets	8,422			7,094			3,305			2,731
Funded status	(527		)	(1,176		)	(591		)	(619		)

Certain international pension plans were underfunded as of December 31, 2004 and 2003. The accumulated benefit obligations of these plans were $1.378 billion in 2004 and $764 million in 2003. The assets of these plans were $1.073 billion in 2004 and $402 million in 2003. The net underfunded amounts are included in current and other liabilities on the Consolidated Balance Sheet.

Following is a reconciliation of the beginning and ending balances of the benefit obligation and the fair value of plan assets as of the plan measurement dates:

3M’s investment strategy for its pension and postretirement plans is to manage the plans on a going-concern basis. The primary goal of the funds is to meet the obligations as required. The secondary goal is to earn the highest rate of return possible, without jeopardizing its primary goal, and without subjecting the Company to an undue amount of contribution rate volatility. Fund returns are used to help finance present and future obligations to the extent possible within actuarially determined funding limits and tax-determined asset limits, thus reducing the level of contributions 3M must make.

3M does not buy or sell any of its own stock as a direct investment for its pension and other postretirement benefit funds. However, due to external investment management of the funds, the plans may indirectly buy, sell or hold 3M stock. The aggregate amount of the shares would not be considered to be material relative to the aggregate fund percentages.

For the U.S. pension plan, the Company’s assumption for the expected return on plan assets was 9.0% in 2004. In developing the expected long-term rate of return assumption, the Company is provided projected returns by asset class from its pension investment advisors. Projected returns are based primarily on broad, publicly traded equity and fixed-income indices and forward-looking estimates of active investment management. The Company’s expected long-term rate of return on U.S. plan assets is based on an asset allocation assumption of 44% U.S. and 15% international equities, with an expected long-term rate of return of 7.5% for both U.S. and international equities; 13% private equities with an expected long-term rate of return of 12.5%; 28% fixed-income securities with an expected long-term rate of return of 5.0%; and an additional rate of return of 1.5% from active investment management. These assumptions result in a 9.0% weighted average rate of return on an annualized basis. The plan assets earned a rate of return in excess of 13% and 18% in 2004 and 2003, respectively, and substantially less than 9% in 2002. The average annual actual return on the plan assets over the past 10 and 25 years has been 11.7% and 12.5%, respectively. The Company is lowering the 2005 expected return on plan assets by 0.25 percentage points to 8.75%.

The U.S. plan’s asset allocation by asset category as of plan measurement dates follows:

Asset Category	Target Allocation		Percentage of Plan Assets
Asset Category	2005		2004		2003
U.S. qualified pension plan
Domestic equity	44	%	46	%	42	%
International equity	15		17		16
Fixed income	28		27		28
Private equity	13		9		9
Cash	—		1		5

Fixed income	11		10		9
Private equity	18		8		7
Cash	—		—		2
Total	100	%	100	%	100	%

While the target asset allocations do not have a percentage allocated to cash, the plans will always have some cash due to cash flows. As of September 30, 2003, the plans had more cash than typically would be held due to third quarter cash contributions to the plans. The preceding postretirement allocation represents a weighted-average allocation for U.S. plans.

The international plans’ weighted-average asset allocation as of December 31, 2004 follows:

Asset Category	Percentage of Plan Assets
International pension plans
Domestic equity	30	%
Foreign equity	23
Domestic fixed income	15
Foreign fixed income	9
Insurance	19
Real estate	2
Cash	2
Total	100	%

The preceding asset allocations for international plans represent the top six countries by projected benefit obligation. These countries represent approximately 90% of the total international projected benefit obligation. The other countries’ asset allocations would not have a significant impact on the information presented.

3M made a third quarter 2004 special pension contribution of $300 million to its U.S. qualified pension plan. Also, in the third quarter of 2004, 3M made a plan design change to its Sumitomo 3M Japanese pension plan that changed the defined benefit plan to a hybrid defined contribution and cash balance plan. Prior to implementation of the plan design change, Japanese pension valuation methods required 3M to bring the plan to fully funded status. This required 3M to make a third quarter 2004 special pension contribution of $155 million. The plan design change reduced the liability by approximately $100 million. In addition, during the second half of 2005, 3M intends to transfer a portion of its Sumitomo 3M Japanese pension liabilities and assets to the government, as allowed by a Japanese government program. This program would allow 3M to transfer approximately $150 million in pension liabilities and $80 million in pension assets to the Japanese government.

In 2005, the Company expects to contribute an amount in the range of $100 million to $400 million to its U.S. and international pension plans, and approximately $150 million to its post-retirement plans. The Company does not have a required minimum pension contribution obligation for its U.S. plans in 2005. Therefore, the amount of the anticipated discretionary contribution could vary significantly depending on the U.S. plans funding status as of the 2005 measurement date and the anticipated tax deductibility of the contribution.

NOTE 12. Commitments and Contingencies

Capital and Operating Leases:
Rental expense under operating leases was $181 million in 2004, $162 million in 2003 and $137 million in 2002. It is 3M’s practice to secure renewal rights for leases, thereby giving 3M the right, but not the obligation, to maintain a presence in a leased facility. 3M’s primary capital lease, effective in April 2003, involves a building in the United Kingdom (with a lease term of 22 years). During the second quarter of 2003, 3M recorded a capital lease asset and obligation of approximately 33.5 million United Kingdom pounds (approximately $64 million at December 31, 2004 exchange rates). Minimum lease payments under capital and operating leases with non-cancelable terms in excess of one year as of December 31, 2004, were as follows:

(Millions)	Capital Leases		Operating Leases
2005	$	5	$	93

Total	106		$	340
Less: Amounts representing interest	31
Present value of future minimum lease payments	75
Less: Current obligations under capital leases	4
Long-term obligations under capital leases	$	71

Warranties/Guarantees:
3M’s accrued product warranty liabilities, recorded on the Consolidated Balance Sheet as part of current and long-term liabilities, are estimated at approximately $22 million. 3M does not consider this amount to be material. The fair value of 3M guarantees of loans with third parties and other guarantee arrangements are not material.

Related Party Activity:
Purchases from related parties (largely related to companies in which 3M has an equity interest) totaled approximately $124 million in 2004 ($113 million in 2003 and $87 million in 2002). Receivables due from related parties (largely related to receivables from employees for relocation and other ordinary business expense advances) totaled approximately $34 million in 2004 ($44 million in 2003 and $25 million in 2002). 3M sales to related parties totaled approximately $91 million in 2004 ($96 million in 2003; not material in 2002). Indebtedness to 3M from related parties was not material in 2004, 2003 and 2002.

Legal Proceedings:
Discussion of legal matters is incorporated by reference from Part I, Item 3, Legal Proceedings, of this document, and should be considered an integral part of the Consolidated Financial Statements and Notes.

NOTE 13. Employee Savings and Stock Ownership Plans

The Company sponsors employee savings plans under Section 401(k) of the Internal Revenue Code. These plans are offered to substantially all regular U.S. employees. Employee contributions of up to 6% of compensation are matched at rates ranging from 35% to 50%, with additional Company contributions depending upon Company performance. All Company contributions initially are invested in 3M common stock, with employee contributions invested in a number of investment funds pursuant to their elections. Vested employees may sell up to 50% of their 3M shares and diversify into other investment options.

The Company maintains an Employee Stock Ownership Plan (ESOP). This plan was established in 1989 as a cost-effective way of funding the majority of the Company’s contributions under 401(k) employee savings plans. Total ESOP shares are considered to be shares outstanding for earnings per share calculations.

Dividends on shares held by the ESOP are paid to the ESOP trust and, together with Company contributions, are used by the ESOP to repay principal and interest on the outstanding notes. The tax benefit related to dividends paid on unallocated shares was charged directly to equity and totaled approximately $4 million in 2004, $5 million in 2003 and $6 million in 2002. Over the life of the notes, shares are released for allocation to participants based on the ratio of the current year’s debt service to the remaining debt service prior to the current payment.

The ESOP has been the primary funding source for the Company’s employee savings plans. As permitted by AICPA Statement of Position 93-6, “Employers’ Accounting for Employee Stock Ownership Plans”, the Company has elected to continue its practices, which are based on Statement of Position 76-3, “Accounting Practices for Certain Employee Stock Ownership Plans” and subsequent consensus of the EITF of the FASB. Accordingly, the debt of the ESOP is recorded as debt, and shares pledged as collateral are reported as unearned compensation in the Consolidated Balance Sheet and Consolidated Statement of Changes in Stockholders’ Equity and Comprehensive Income. Unearned compensation is reduced symmetrically as the ESOP makes principal payments on the debt. Expenses related to the ESOP include total debt service on the notes, less dividends. The Company contributes treasury shares, accounted for at fair value, to employee savings plans to cover obligations not funded by the ESOP (reported as an employee benefit expense).

NOTE 14. General Employees’ Stock Purchase Plan (GESPP)

In May 1997, shareholders approved 30 million shares for issuance under the Company’s GESPP. Substantially all employees are eligible to participate in the plan. Participants are granted options at 85% of market value at the date of grant. There are no GESPP shares under option at the beginning or end of each year because options are granted on the first business day and exercised on the last business day of the same month.

*Weighted average

The weighted average fair value per option granted during 2004, 2003 and 2002 was $12.29, $10.09 and $9.09, respectively. The fair value of GESPP options was based on the 15% purchase price discount.

NOTE 15. Management Stock Ownership Program (MSOP)

In May 2002, shareholders approved 45.4 million shares for issuance under the MSOP in the form of management stock options, restricted stock and stock appreciation rights. Under the plan, the Company has principally issued management stock options that are granted at market value at the date of grant. These options generally are exercisable one year after the date of grant and expire 10 years from the date of grant. Thus, outstanding shares under option include grants from previous plans. There were approximately 14,600 participants in the plan at December 31, 2004.

NOTE 16. Business Segments

Effective January 1, 2005, as part of the continuing effort to drive growth by aligning businesses around markets and customers, the Electronics Markets Materials Division and certain high temperature and display tapes (2004 sales of approximately $350 million) within the Industrial Business transferred to the Electro and Communications Business, and the converter markets product line (2004 sales of approximately $10 million) within the Transportation Business transferred to the Display and Graphics Business. Internal management reporting for these business segment transfers commenced January 1, 2005, with segment information for all periods presented adjusted to reflect the new segment structure.

3M’s businesses are organized, managed and internally reported as seven segments based on differences in products, technologies and services. These segments have worldwide responsibility for virtually all of the Company’s product lines. 3M is not dependent on any single product 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 and other financial information shown. The allocations resulting from the shared utilization of assets are not necessarily indicative of the underlying activity for segment assets, depreciation and amortization, and capital expenditures.

Segment assets for the seven operating business segments (excluding Corporate and Unallocated) primarily include accounts receivable; inventory; property, plant and equipment — net; goodwill and intangible assets; and other miscellaneous assets. Assets included in Corporate and Unallocated principally are cash and cash equivalents; insurance receivables; deferred income taxes; certain investments and other assets, including prepaid pension assets; and certain unallocated property, plant and equipment. Corporate and Unallocated assets increased approximately $2.6 billion in 2004, primarily due to increases in prepaid pension assets ($2.0 billion) and increases in cash and cash equivalents ($0.9 billion), with partial offsets in other asset accounts. Corporate and Unallocated assets increased approximately $2.0 billion in 2003 due to increases in cash and cash equivalents ($1.2 billion), increases in other current assets and other assets primarily related to higher insurance receivables and prepaid items ($500 million), and goodwill increases related to the 2003 acquisition of an additional 25% of Sumitomo 3M ($300 million). For management reporting purposes, corporate goodwill (which at December 31, 2004, totaled approximately $360 million), is not allocated to the seven operating business segments. In Note 3 to the Consolidated Financial Statements, corporate goodwill has been allocated to the respective market segments as required by SFAS No. 142 for impairment testing.

Corporate and Unallocated operating income principally includes corporate investment gains and losses, certain derivative gains and losses, insurance-related gains and losses, certain litigation expenses, corporate restructuring program charges and other miscellaneous items. Because this category includes a variety of miscellaneous items, it is subject to fluctuation on a quarterly and annual basis. In 2004, Corporate and Unallocated operating income includes increases of $40 million in the respirator mask/asbestos litigation reserves, partially offset by a $20 million increase in the associated receivables resulting in a net cost of $20 million, and also includes a $6 million increase in implant litigation reserves and a $10 million decrease in implant receivables resulting in a net cost of $16 million. In 2003, this includes a pre-tax charge of $93 million recorded during the first quarter related to an adverse ruling associated with a lawsuit filed against 3M in 1997 by LePage’s Inc. Corporate and unallocated operating income in 2003 also includes increases of $231 million in the respirator mask/asbestos litigation reserves, partially offset by a $205 million increase in the associated receivables, resulting in a net cost of $26 million. In 2002, Corporate and Unallocated operating income includes charges of $202 million related to the 2001/2002 corporate restructuring program. Depreciation and amortization of $954 million included accelerated depreciation (shortened lives) of $47 million related to the restructuring plan (recorded in Corporate and Unallocated).

NOTE 17. Geographic Areas

Effective January 1, 2005, the company realigned its reporting for the African Region, which previously was included in the Latin America/Canada area, to the Europe and Middle East area. Reporting for this new geographic area structure commenced January 1, 2005, with geographic area information for all periods presented adjusted to reflect the new structure. Geographic area information is used by the Company as a secondary performance measure to manage its businesses. Export sales and certain income and expense items are reported within the geographic area where the final sales to 3M customers are made.
