Minnesota Mining and Manufacturing Company and Subsidiaries
Notes to Consolidated Financial Statements

(Unaudited)
The interim consolidated financial statements are unaudited but, in the opinion of management, reflect all adjustments necessary for a fair presentation of financial position, results of operations and cash flows for the periods presented. These adjustments consist of normal, recurring items, except for non-recurring items in the third quarter of 2000, primarily relating to costs to phase out perfluorooctanyl chemistry production and gains related to asset dispositions; a benefit from the termination of a product distribution agreement in the first quarter of 2000; and non- recurring items relating to divestitures (net of an investment valuation adjustment), litigation and restructuring activities in the second and third quarters of 1999. The results of operations for any interim period are not necessarily indicative of results for the full year. The interim consolidated financial statements and notes are presented as permitted by the requirements of Form 10-Q and do not contain certain information included in the company's annual consolidated financial statements and notes. This Form 10-Q should be read in conjunction with the company's consolidated financial statements and notes included in its 1999 Annual Report on Form 10-K.
Acquisitions:
In separate transactions during the second and third quarters of 2000, 3M acquired about 85 percent of Quante AG (a telecommunications company) and 100 percent of five smaller businesses for a total purchase price of $307 million in cash (net of cash acquired) plus 128,994 shares of 3M common stock. The stock had a fair market value of $11 million at the acquisition date and was previously held as 3M treasury stock. All of these transactions were accounted for using the purchase method of accounting. The preliminary estimated fair values of assets acquired and liabilities assumed relating to these acquisitions are summarized below:

Amounts in millions - Asset (Liability):
Accounts receivable           $ 86
Inventories                     99
Other working capital - net    (93)
Property, plant and equipment  140
Purchased intangible assets    182
Other assets                    30
Interest bearing debt          (99)
Long-term liabilities          (27)
  Net assets acquired         $318	

The purchased intangible assets, including goodwill, are being amortized on a straight-line basis over the periods benefited, ranging from three to twenty years. In-process research and development charges associated with these acquisitions were not significant. The company has made a tender offer for the remaining shares outstanding of Quante AG. Proforma information related to these acquisitions is not included as the impact of these acquisitions on the company's results of operations is not considered to be significant.

Specialty Material - Perfluorooctanyl Chemistry Phase Out:
In May 2000, 3M announced its intent to substantially phase out production by the end of 2000 of the perfluorooctanyl chemistry used to produce certain repellents and surfactant products. These include many Scotchgard brand products, such as soil, oil and water repellent products; coatings used for oil and grease resistance on paper packaging; fire-fighting foams; and specialty components for other products. The affected product lines represent about $300 million in annual sales with an operating income margin around 20 percent.
In the third quarter of 2000, after further analysis of the alternative future use of productive assets impacted by the perfluorooctanyl phase-out, the company determined that certain affected equipment was not expected to be utilized after the phase- out. The company determined that estimated future undiscounted cash flows were insufficient to recover the related carrying values. Accordingly, the carrying value of these assets was written down by $48 million to reflect the company's estimates of fair value (determined by discounting estimated future cash flows). The other components of the $106 million in phase-out costs include $29 million for accelerated depreciation, and other incremental costs directly related to the phase-out. This $106 million charge is recorded in cost of goods sold. The company expects to incur additional phase-out costs in future periods of approximately $50 million, primarily related to accelerated depreciation and severance.
Company Restructuring Charge:
As of December 31, 1999, the company-wide restructuring program, initiated in the second half of 1998, was substantially complete. This is discussed in the 1999 Form 10-K. Because certain employees can defer receipt of termination benefits for up to 12 months, cash payments in the first nine months of 2000 relate primarily to previous terminations. Selected information relating to the restructuring liability follows.

Restructuring                       Employee
Liability                        Termination
(Millions)                          Benefits      Other       Total
December 31, 1999 liability           $ 31         $ 8         $ 39

   Second quarter 2000                  (1)         (1)          (2)
   Third quarter 2000                   (2)         (3)          (5)
September 30, 2000 liability          $ 10         $ 3         $ 13	

Financial Instruments:
In the second and third quarters of 2000, the company entered into additional foreign exchange forward contracts, primarily in Euros and Japanese yen, to reduce exchange rate risk arising from cross-border financing activities denominated in foreign currencies. This increased the forward contracts face amounts from $997 million at year-end 1999 to about $1.4 billion at September 30, 2000. The amounts at risk are not material because the company has the ability to generate offsetting foreign currency cash flows.
Business Segments:
In the first quarter of 2000, business segment operating income for 1999 was restated for minor amounts, to be consistent with year 2000 management reporting practices. Certain costs previously included in Corporate and Unallocated were allocated to the individual business segments. 3M net sales and operating income by segment for 1999 and 2000 follow.

Several non-recurring items impacted the operating income by business segment. Third quarter 2000 operating income includes non-recurring costs of $118 million (included in cost of goods sold) and non- recurring gains of $119 million. Non-recurring items in the third quarter of 2000 include $106 million of costs in the Specialty Material segment relating to the company's phase out of perfluorooctanyl chemistry. Remaining non-recurring items in the third quarter of 2000 were largely gains related to asset dispositions, principally the sale of available-for-sale equity securities, and are primarily recorded in Corporate and Unallocated. First quarter 2000 operating income includes a $50 million benefit relating to the termination of a product distribution agreement in the Health Care segment. Third quarter 1999 operating income includes a $43 million gain related to divestitures, mainly in the Health Care segment, and Corporate and Unallocated includes $73 million in litigation expense partially offset by a $26 million change in estimate that reduced the restructuring charge. Second quarter 1999 operating income includes gains on divestitures, net of an investment valuation adjustment, of $30 million in the Health Care segment and $74 million in Corporate and Unallocated.
Accounting Pronouncements:
In December 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 101, "Revenue Recognition." An amendment in June 2000 delayed the effective date until the fourth quarter of 2000. The company is reviewing the requirements of this standard and is evaluating the potential effects on its consolidated financial statements.
In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities." SFAS No. 133, as amended, must be adopted by the company no later than January 1, 2001. Based on the company's current derivative positions, the company does not expect this standard to materially affect its financial position or results of operations.

As required by a recent Emerging Issues Task Force (EITF) consensus, stock option income tax benefits have been classified as a component of cash flows from operating activities in the consolidated statement of cash flows. Prior period consolidated statement of cash flows amounts have been restated to conform with this presentation.
Debt Issuance:
In September 2000, the company completed a 3-year, 16 billion yen (approximately $150 million), 1.0 percent Euro Yen Bond offering.
Shelf Registration:
On October 30, 2000, the company filed a shelf registration with the Securities and Exchange Commission. This registration provides the means to offer debt securities of up to $1.5 billion. 3M plans to use the net proceeds from future issuances of debt securities under this shelf registration for general corporate purposes, including the repayment of debt, investments in or extensions of credit to the company's subsidiaries, or the financing of possible acquisitions or business combinations.
Earnings Per Share:
The difference in the weighted average common shares outstanding for calculating basic and diluted earnings per share is attributable to the assumed exercise of the Management Stock Ownership Program (MSOP) stock options for the three-month and nine-month periods ended September 30, 2000 and 1999. Certain MSOP options outstanding were not included in the computation of diluted earnings per share because they would not have had a dilutive effect (about 5.2 million to 16.0 million shares for the periods presented).
Comprehensive Income:
The components of total comprehensive income are shown below. In the third quarter of 2000, deferred income taxes for the unrealized loss on debt and equity securities totaled $18 million. For the third quarter of 1999, deferred income taxes for the unrealized gain on debt and equity securities totaled $30 million, and in the first nine months of 2000 and 1999 totaled $7 million and $59 million, respectively. Reclassification adjustments in the third quarter and first nine months of 2000 for realized gains included in income totaled $85 million ($52 million after tax). These gains related to the sale of available-for-sale marketable equity securities.

Common Stock:
At the Annual Meeting of Stockholders held on May 9, 2000, the company's shareholders approved amendments to the company's Restated Certificate of Incorporation (i) to increase the number of authorized shares of common stock of the company to 1.5 billion shares and (ii) to change the par value of the company's common stock to $.01 per share. This change resulted in a reclassification of $231 million from common stock to capital in excess of par value.
Other:
Discussion of legal matters is cross-referenced to this Form 10-Q, Part II, Item 1, Legal Proceedings, and should be considered an integral part of the interim consolidated financial statements.
PricewaterhouseCoopers LLP, the company's independent auditors, have performed a review of the unaudited interim consolidated financial statements included herein, and their review report thereon accompanies this filing.

Review Report of Independent Auditors
To the Stockholders and Board of Directors of Minnesota Mining and Manufacturing Company:
We have reviewed the accompanying consolidated balance sheet of Minnesota Mining and Manufacturing Company and Subsidiaries as of September 30, 2000, and the related consolidated statements of income for each of the three-month and nine-month periods ended September 30, 2000 and 1999, and of cash flows for the nine-month periods ended September 30, 2000 and 1999. These financial statements are the responsibility of the Company's management.
We conducted our reviews in accordance with standards established by the American Institute of Certified Public Accountants. A review of interim financial information consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in the United States of America, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
Based on our reviews, we are not aware of any material modifications that should be made to the accompanying consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.
We previously audited, in accordance with auditing standards generally accepted in the United States of America, the consolidated balance sheet as of December 31, 1999, and the related consolidated statements of income, of changes in stockholders' equity and comprehensive income, and of cash flows for the year then ended (not presented herein); and in our report dated February 14, 2000, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 1999, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

Management's Discussion and Analysis of Financial Condition and Results of Operations
RESULTS OF OPERATIONS
 Third Quarter
Worldwide sales for the third quarter totaled $4.252 billion, up 6.4 percent from the third quarter last year. Volume increased 11 percent on a reported basis and 8.5 percent excluding acquisitions and divestitures. Selling prices worldwide declined about 1.5 percent, largely due to volume-related price reductions in 3M's electronics business, which posted strong volume gains. Currency, driven by the weak Euro, decreased worldwide sales by about 3 percent.
In the United States, sales totaled $2.040 billion, with volume up 5.5 percent. U.S. selling prices declined 1 percent overall.
Internationally, sales totaled $2.212 billion, up about 8 percent in dollars. Volume increased 16 percent and selling prices decreased about 2 percent. Adjusting for the acquisition of Quante AG, a manufacturer of telecommunications products and systems, volume increased about 12 percent. Currency reduced international sales by 6 percent, driven by negative currency translation of 13 percent in Europe.
European volume increased about 18 percent. Adjusting for the acquisition of Quante AG, volume increased about 8 percent. In the Asia Pacific area, volume increased 17 percent. In Asia outside Japan, volume increased 22 percent, led by Korea and the China region. In Japan, volume increased 17 percent. In Latin America, volume increased about 11 percent, with strong growth in Mexico and good growth in Brazil. In Canada, volume increased 7 percent.
Cost of goods sold includes non-recurring costs of $118 million, primarily related to the company's decision to phase-out its perfluorooctanyl chemistry. Excluding these costs, cost of goods sold was 55.6 percent of sales, down eight-tenths of a percentage point from the third quarter last year. Gross margins benefited from a strong performance in our factories, volume growth, productivity gains and lower employee benefit costs, but were negatively affected by raw material costs and currency effects. Cost of goods sold includes manufacturing; research, development, and related expenses; and engineering expenses.
Selling, general and administrative expenses were 25.2 percent of sales, up from 24.4 percent in the third quarter of last year. These expenses reflected higher advertising and promotion expenses, but benefited from lower employee benefit costs.
The non-recurring restructuring pre-tax credit of $26 million in 1999 related to changes in estimates that reduced certain restructuring charges originally recorded in the second half of 1998.

Other operating income in the third quarter of 2000 includes non- recurring gains of approximately $119 million related to asset dispositions, principally the sale of available-for-sale equity securities. Other operating expense in the third quarter of 1999 reflects a pre-tax charge of $30 million related to two non-recurring items. A pre-tax charge of $73 million was recorded relating to an adverse jury verdict and legal fees associated with a lawsuit filed by LePage's, Inc. 3M also recorded a pre-tax gain of $43 million related to divestitures, mainly in the Health Care segment.
The following discussion excludes the impact of third quarter 2000 and 1999 non-recurring items.

Worldwide operating income was 19.2 percent of sales, the same as in the third quarter last year.
Third-quarter interest expense of $29 million was $3 million higher than the third quarter last year, reflecting higher interest rates. Investment and other income was $4 million, compared with $7 million in the same quarter last year, reflecting slightly lower interest income.
The worldwide effective income tax rate for the quarter was 34.4 percent, down from 35.0 percent in the third quarter last year.
Minority interest was $21 million, compared with $23 million in the third quarter of 1999. The decrease is a result of 3M's acquisition of the 46 percent minority interest in Dyneon in December of 1999, largely offset by higher profits in Sumitomo 3M Limited.
Net income for the third quarter of 2000 totaled $499 million, or $1.25 per diluted share, compared with $462 million, or $1.14 per diluted share, in the third quarter of 1999. The company estimates that changes in the value of the U.S. dollar decreased earnings for the

quarter by about 2 cents per share compared with the third quarter of 1999. 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 exchange rate risks. Derivative transactions resulted in a net pre-tax gain of $9 million (included in cost of goods sold) in the third quarter of 2000, primarily related to terminated foreign exchange forward contracts which had been used to hedge Euro exposure.
First Nine Months
Worldwide sales for the first nine months totaled $12.528 billion, up 7.7 percent from the same period last year. Volume increased 11 percent on a reported basis and 10 percent adjusted for acquisitions and divestitures. Selling prices worldwide declined about 1.5 percent, largely due to volume-related price reductions in 3M's electronics business, which posted strong volume gains. Currency decreased worldwide sales by about 2 percent.
In the United States, sales totaled $5.890 billion, with volume up 7 percent and selling prices down 1 percent overall. Internationally, sales totaled $6.638 billion. Volume increased 15 percent, while selling prices were down about 2 percent, resulting in overall local- currency sales gains of about 13 percent. Currency translation reduced international sales by 3.5 percent.
Cost of goods sold includes non-recurring costs of $118 million, primarily related to the company's decision to phase out its perfluorooctanyl chemistry. Excluding these costs, cost of goods sold was 56.0 percent of sales, down eight-tenths of a percentage point from the same period last year. Gross margins benefited from a strong performance in our factories, volume growth, productivity gains and lower employee benefit costs, but were negatively affected by raw material costs and currency effects. Cost of goods sold includes manufacturing; research, development, and related expenses; and engineering expenses.
Selling, general and administrative expenses were 25.2 percent of sales, compared with 25.0 percent in the same period last year. These expenses reflected higher advertising and promotion expenses, but benefited from lower employee benefit costs.
Other operating income in the first nine months of 2000 includes non- recurring gains of $169 million. These gains include $119 million relating to asset dispositions, principally the sale of available-for- sale equity securities, and also reflect a pre-tax benefit of $50 million associated with the termination of a product marketing and distribution agreement in the health care segment. Results for the first nine months of 1999 reflect a pre-tax benefit of $100 million relating to gains on divestitures (net of an investment valuation adjustment), litigation and restructuring activities. The impact of these items on 3M's Consolidated Statement of Income follows.

The following discussion excludes the impact of non-recurring items.

Worldwide  operating income was 18.8 percent of sales, up  six-tenths
of  a  percentage point from the same period last year. Volume growth
and  productivity  gains drove most of the improvement  in  worldwide
operating   income.   The  lower  employee  benefit  costs  discussed
previously is the result of lower pension expense, primarily  in  the
United  States.   This estimated five-tenths of  a  percentage  point
improvement  is  more than offset by higher payroll costs  and  other
inflationary impacts.

Interest expense for the first nine months was $81 million,  down  $2
million  from  the same period last year.  Net investment  and  other
income  was $16 million, compared with $22 million in the first  nine
months of 1999.

The worldwide effective income tax rate for the first nine months was
34.9 percent, down from 35.5 percent in the same period last year.

Minority interest was $69 million, compared with $58 million  in  the
same period of 1999. The increase reflects higher profits in Sumitomo
3M  Limited,  partially offset by a decrease  as  a  result  of  3M's
acquisition of the 46 percent minority interest in Dyneon in December
of 1999.

Net  income for the first nine months of 2000 totaled $1.425 billion,
or  $3.56  per diluted share, compared with $1.267 billion, or  $3.12
per diluted share, in the same period of 1999.  The company estimates
that  changes in the value of the U.S. dollar decreased earnings  for
the  first  nine  months of 2000 by about 8 cents per share  compared
with  the same period of 1999.  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 exchange
rate risks.	

Performance by Business Segment
The  following is a discussion of the global operating results of the
company's  six  business segments.  The discussion  applies  to  both
third   quarter  and  first  nine  month  results  unless   otherwise
indicated.

In  Industrial  Markets,  sales for the  third  quarter  increased  7
percent  in  local currencies and 4 percent in dollars, and  for  the
first nine months sales increased 8 percent in local currencies and 6
percent   in  dollars.   Leading  growth  in  this  market  was   the
Superabrasives and Microfinishing Systems business, which is  growing
through  strong  demand  for proprietary 3M  abrasives  used  in  the
electronics  and  telecommunications industries.  Industrial  Markets
also  saw  good  growth in packaging and bonding tapes and  specialty
adhesives. Profits of this market increased in the third quarter  and
first  nine months of 2000 compared with the same periods last  year.
Operating  income  improvement was driven by volume gains,  increased
manufacturing efficiencies, and other cost improvements.

In  the  Transportation, Graphics and Safety segment, sales  for  the
third  quarter increased 11 percent in local currencies and 8 percent
in  dollars, and for the first nine months rose 12 percent  in  local
currencies  and 11 percent in dollars.  Optical Systems continued  to
show  outstanding growth.  This business provides optical  films  for
computer  monitors,  electronic organizers,  cell  phones  and  other
devices  with electronic displays.  At the end of second  quarter  of
2000,  3M  acquired  a  manufacturer of  touch  screens  and  related
products,  which  adds  product  offerings  to  the  Optical  Systems
business. The occupational health and safety, automotive, and  safety
and  security businesses also turned in good worldwide sales  growth.
Operating  income  margins were down slightly in the  third  quarter,
affected by acquisition-related costs. Double-digit sales growth  and
productivity  gains  drove margin improvements  for  the  first  nine
months.

In  the  Health Care segment, sales for the third quarter were  up  5
percent in local currencies and up 1 percent in dollars, and for  the
first nine months rose 3 percent in local currencies and were flat in
dollars.   Excluding  acquisitions and  divestitures,  local-currency
health care sales increased about 6 percent for the first nine months
of  2000.  Leading  this  growth was the health  information  systems
business. The dental business also showed good sales growth.

Non-recurring  items  in Health Care in the  first  quarter  of  2000
include  a  $50  million gain associated with the  termination  of  a
product  distribution agreement. A new co-promotion and  distribution
agreement  was  entered  into in the fourth quarter  of  2000.   Non-
recurring  items  in the first nine months of 1999 include  gains  on
divestitures   of   $62  million.   Excluding  non-recurring   items,
operating income improved in the third quarter, while the first  nine
months  was  relatively flat, affected by the impact of  divestitures
made in 1999 and by inflationary and spending increases in 2000.

In  the  Consumer  and Office segment, sales for  the  third  quarter
increased  more than 8 percent in local currencies and 5  percent  in
dollars,  and for the first nine months increased about 9 percent  in
local  currencies and 7 percent in dollars.  The office supply,  home	

care  and  do-it-yourself businesses drove higher  revenues.  Profits
rose in the third quarter and the first nine months, mainly due to solid
volume gains.  Increased advertising and promotion expenses, together
with strong relationships with retailers, helped to drive this volume
growth.

In  the  Electro and Communications segment, revenues for  the  third
quarter  and  first  nine  months  increased  24  percent  in   local
currencies   and   more  than  22  percent  in  dollars.    Excluding
acquisitions, revenues for the third quarter increased 6 percent  and
for  the  first nine months increased 11 percent. In the  second  and
third quarters of 2000, 3M acquired about 85 percent of the total shares
outstanding of Quante AG, a German telecommunications company.  Sales
of  Quante  AG in 1999 were approximately $350 million.  This  market
continued  to  see  strong growth in Microflex circuits,  connectors,
telecom, and electronic handling and protection products.  Profits of
this  market  decreased in the third quarter, but showed good  growth
for  the first nine months.  Profits grew more slowly than sales  due
to  volume-related price decreases in certain 3M electronic  products
and   acquisition-related  costs  associated  with  the   Quante   AG
acquisition.

In  the  Specialty  Material segment, sales  for  the  third  quarter
increased  1 percent in local currencies and were down 2  percent  in
dollars,  and for the first nine months sales increased 4 percent  in
local  currencies  and  about 2 percent in dollars.  High-performance
materials for telecommunications and electronics markets posted solid
gains.  In  May 2000, 3M announced its intent to substantially  phase
out  production by the end of 2000 of the perfluorooctanyl  chemistry
used  to  produce  certain  repellents and surfactant  products.  The
affected  product lines represent about $300 million in annual  sales
with  an  operating income margin around 20 percent.   Overall  sales
were   affected  by  this  phase-out.   The  company  is  introducing
alternatives  that are gaining customer acceptance and should  enable
3M  to retain an important portion of this business. Operating income
in  the  third quarter of 2000 includes non-recurring costs  of  $106
million   related  to  the  company's  decision  to   phase-out   the
perfluorooctanyl  chemistry.  Excluding  these  costs,  this  segment
reported  good operating income results for the quarter and  for  the
first nine months.

FINANCIAL CONDITION AND LIQUIDITY
The  company's  financial  condition  and  liquidity  remain  strong.
Working  capital  totaled  $1.821  billion  at  September  30,  2000,
compared with $2.247 billion at year-end 1999.  The company's current
ratio  was 1.4, down from 1.6 at year-end.  Working capital  and  the
current  ratio  were  both  impacted by  higher  short-term  debt  at
September 30, 2000, largely relating to acquisitions, compared with a
lower  short-term  debt  balance at  December  31,  1999,  helped  by
business   divestiture  proceeds  received  in  1999.  The   accounts
receivable average days' sales outstanding was 59 days, down from  61
days  at  year-end, but the same as September 30, 1999. The company's
inventory  index, which represents the average number  of  months  of
inventory  on-hand, was 3.2 months, up slightly from  3.1  months  at
year-end.	

Total  debt  increased  $164 million from year-end  1999  to  $2.774
billion.  As  of September 30, 2000, total debt was  30  percent  of
total capital.

The  company's strong credit rating provides ready and ample  access
to  funds  in  global capital markets. At September  30,  2000,  the
company had available short-term lines of credit totaling about $768
million.

Net  cash provided by operating activities totaled $1.768 billion  in
the  first nine months of the year, down $672 million from  the  same
period last year. In 2000, depreciation and amortization includes $29
million  for  accelerated depreciation relating to the phase  out  of
perfluorooctanyl   chemistry.  In  2000,  accounts   receivable   and
inventory dollars increased, primarily due to solid sales growth.  In
1999,  the  company had benefits in working capital and other  areas.
Net cash inflows from mammary implant litigation were $51 million  in
the  first nine months of 2000, compared with $44 million in net cash
inflows in the same period last year.

Timing differences between payment of implant liabilities and receipt
of related insurance recoveries could affect the cash flows of future
periods.  This is discussed in Part II, Item 1, Legal Proceedings, of
this Form 10-Q.

Cash  used in investing activities totaled $884 million in the  first
nine  months  of  the year, compared with $522 million  in  the  same
period  last year. Capital expenditures for the first nine months  of
2000  were $673 million, a decrease of about 7 percent from the  same
period  last year. Proceeds from sales of businesses in 1999 totaling
$248  million  related to divestitures of Eastern  Heights  Bank  and
certain  health care businesses. In the third quarter  of  2000,  the
company  sold  an available-for-sale equity security  with  net  cash
proceeds of $93 million.

In  the  second and third quarters of 2000, in separate transactions,
3M  acquired  about 85 percent of Quante AG and 100 percent  of  five
smaller businesses for a total purchase price of $307 million in cash
(net  of cash acquired) plus 128,994 shares of 3M common stock. Refer
to  "Acquisitions" in the Notes to Consolidated Financial  Statements
for details concerning these acquisitions.

In October 2000, the company finalized the acquisition of a Wisconsin-
based  single-chip module substrate business. The company expects  to
complete  additional  business  combinations  in  the  near  future,
dependent  upon necessary approvals, including 1) acquiring  Robinson
Nugent, Inc., which provides electronic  connector  products  for the
telecommunications  market  and  2) combining  3M's  Dental  Products
Division  with ESPE Dental AG, a Munich, Germany-based developer  and
manufacturer  of high-quality products and delivery systems  for  the
dental  profession.   The  company continues  to  explore  additional
acquisition opportunities.	

Financing activities in the first nine months of 2000 for both short-
term  and  long-term debt included net cash inflows of $205  million,
compared  with net cash outflows of $897 million in the  same  period
last  year.  In September 2000, the company completed  a  3-year,  16
billion  yen (approximately $150 million), 1.0 percent Euro Yen  Bond
offering.    On  October  30,  2000,  the  company  filed   a   shelf
registration  with  the  Securities  and  Exchange  Commission   that
provides the means to offer debt securities of up to $1.5 billion.

Treasury  stock repurchases for the first nine months  of  2000  were
$675  million,  compared with $478 million in the  same  period  last
year.  The  company repurchased about 7.6 million  shares  of  common
stock  in  the  first nine months of 2000, compared  with  about  5.3
million  shares in the same period last year.  In November 1999,  the
Board  of  Directors authorized the repurchase of up  to  12  million
shares of 3M common stock through December 31, 2000.  As of September
30,  2000,  4.4  million shares remained authorized  for  repurchase.
Stock  repurchases are made to support employee stock purchase  plans
and for other corporate purposes, including acquisitions.

Cash dividends paid to shareholders totaled $689 million in the first
nine  months  of this year, compared with $677 million  in  the  same
period  last  year.   In  February 2000, the quarterly  dividend  was
increased to 58 cents per share.  Distributions to minority interests
totaled  $70 million in the first nine months of 2000, compared  with
$49 million in the same period last year, and relate to 3M's minority
interest in Sumitomo 3M Limited and 3M Health Care Limited.

Legal  proceedings are discussed in the Legal Proceedings section  in
Part II, Item 1, of this Form 10-Q.

FUTURE OUTLOOK
The company is not able to project what the consequences will be from
the  dynamic  economies around the world. The company  is  monitoring
business  conditions closely and is prepared to make  adjustments  in
costs, pricing and investments as appropriate.

The  company expects continued solid revenue and earnings  growth  in
the  fourth quarter of 2000.  Volume gains in the fourth quarter  are
expected  to  be a little stronger than the third quarter,  primarily
due  to a resumption of European growth to the levels experienced  in
the  first  half  of 2000. The company estimates, based  on  currency
rates  as  of September 30, 2000, that currency would reduce earnings
for  the year by about 15 cents per share, primarily due to a weaker-
than-anticipated  Euro.  The company expects raw  material  costs  to
increase 1 to 2 percent for the year 2000.  Despite these challenges,
the  company  believes  it will continue to  deliver  solid  results,
helped by strong volume gains and good productivity.

FORWARD-LOOKING STATEMENTS
This   Quarterly   Report  on  Form  10-Q  contains   forward-looking
statements  within  the meaning of the Private Securities  Litigation
Reform Act of 1995.  These statements may be identified by their  use
of   words   like  "plan,"  "expect,"  "aim,"  "believe,"  "project,"
"anticipate,"  "intend," "estimate," "will,"  "should,"  "could"  and
other  expressions  that  indicate  future  events  and  trends.  All
statements that address expectations or projections about the future,
including statements about the company's strategy for growth, product
development, market position, expenditures and financial results  are
forward-looking statements.

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:

*    The effects of, and changes in, worldwide economic conditions -
  The company operates in more than 60 countries and derives more than
  half of its revenues from sales outside the United States.  3M's
  business may be affected by factors in other countries that are
  outside its control, such as downturns in economic activity in a
  specific country or region, the economic difficulties that occurred
  in Asia in 1998 as an example; 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
  - Because 3M derives more than half its revenues from sales outside
  the United States, its ability to realize projected growth rates in
  sales and net earnings and results of operations could be adversely
  affected if the United States dollar strengthens significantly
  against foreign currencies.	

*    The timing and market acceptance of 3M's new product offerings -
  3M's growth objectives are largely dependent on 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; successfully complete clinical trials and obtain regulatory
  approvals; obtain adequate intellectual property protection; or gain
  market acceptance of new products.

*    Raw materials, including shortages and increases in the costs of
  key raw materials.

*    Acquisitions, divestitures and strategic alliances - As part of
  3M's strategy for growth, the company has made and may continue to
  make acquisitions, divestitures and strategic alliances.  However,
  there can be no assurance that these will be completed or beneficial
  to the company.

*    Legal proceedings (see discussion of Legal Proceedings in Part
  II, Item 1 of this Form 10-Q).	

      Minnesota Mining and Manufacturing Company and Subsidiaries
                      PART II.  Other Information

Item 1.  Legal Proceedings
The  company and certain of its subsidiaries are named as defendants
in  a  number  of  actions,  governmental  proceedings  and  claims,
including  environmental proceedings and products  liability  claims
involving  products now or formerly manufactured  and  sold  by  the
company.   In some actions, the claimants seek damages  as  well  as
other   relief,   which,  if  granted,  would  require   substantial
expenditures.  The  company has accrued certain  liabilities,  which
represent reasonable estimates of its probable liabilities for these
matters.  The company also has recorded receivables for the probable
amount of insurance recoverable with respect to these matters.

Some  of these matters raise difficult and complex factual and legal
issues,  and are subject to many uncertainties, including,  but  not
limited  to, the facts and circumstances of each particular  action,
the  jurisdiction and forum in which each action is  proceeding  and
differences  in  applicable law. Accordingly,  the  company  is  not
always   able  to  estimate  the  amount  of  its  possible   future
liabilities with respect to such matters.

There  can be no certainty that the company may not ultimately incur
charges,  whether for governmental proceedings and claims,  products
liability   claims,  or  other  actions,  in  excess  of   presently
established  accruals.   While  such future  charges  could  have  a
material adverse impact on the company's net income in the quarterly
period  in  which they are recorded, the company believes that  such
additional charges, if any, would not have a material adverse effect
on   the   consolidated  financial  position,  annual   results   of
operations,  or  cash  flows of the company.  (NOTE:  The  preceding
sentence  applies  to  all legal proceedings involving  the  company
except  the  breast  implant litigation and  environmental  matters,
which are discussed separately in the next sections).

Breast Implant Litigation

As  previously reported in the company's Annual Report on Form  10-K
for  the year ended December 31, 1999, the company and certain other
companies  have been named as a defendant in a number of claims  and
lawsuits  alleging damages for personal injuries  of  various  types
resulting from breast implants formerly manufactured by the  company
or   a  related  company.  The  company  entered  the  business   of
manufacturing  breast implants in 1977 by purchasing McGhan  Medical
Corporation.   In  1984,  the  company  sold  the  business   to   a
corporation that also was named McGhan Medical Corporation.

As  of  September  30,  2000, the company is currently  named  as  a
defendant, often with multiple co-defendants, in 1,523 lawsuits  and
46  claims  in  various  courts, all seeking  damages  for  personal
injuries  from  allegedly defective breast implants. These  lawsuits
and  claims purport to represent 4,514 individual claimants.  It  is
not  yet  certain how many of these lawsuits and claims involve  (i)
products  manufactured and sold by the company, as opposed to  other	

manufacturers, or (ii) individuals who accepted benefits  under  the
Revised  Settlement  Program (as defined  later).  The  company  has
confirmed that 111 of the 4,514 individual claimants have opted  out
of  the class action and have 3M Implants. The company believes that
most  of  these lawsuits and claims will be dismissed either because
the  claimants  did  not have 3M Implants or the claimants  accepted
benefits under the Revised Settlement Program. The company continues
to work to clarify the status of these lawsuits and claims.

On  December  22,  1995, the Court approved a revised  class  action
settlement  program  for resolution of claims  seeking  damages  for
personal  injuries  from allegedly defective  breast  implants  (the
"Revised  Settlement  Program"). The Court ordered  that,  beginning
after  November 30, 1995, members of the plaintiff class may  choose
to  participate in the Revised Settlement Program or opt out,  which
would  then  allow  them to proceed with separate product  liability
actions.

The   company  believes  that  approximately  90  percent   of   the
registrants,  including those claimants who  filed  current  claims,
have elected to participate in the Revised Settlement Program. It is
still  unknown  as  to  what  disease criteria  all  claimants  have
satisfied,  and  what options they have chosen.  As  a  result,  the
total  amount and timing of the company's prospective payments under
the  Revised Settlement Program cannot be determined with  precision
at  this  time. As of September 30, 2000, the company has paid  $296
million into the court-administered fund as a reserve against  costs
of  claims  payable  by  the company under  the  Revised  Settlement
Program   (including   a  $5  million  administrative   assessment).
Additional payments will be made as necessary. Payments to date have
been  consistent with the company's estimates of the total liability
for these claims.

Under  the  Revised  Settlement Program,  additional  opt  outs  are
expected  to  be minimal since the opt-out deadline has  passed  for
virtually   all   U.S.   class  members.  The  company's   remaining
obligations  under the Revised Settlement Program are limited  since
(i)  most payments to Current Claimants have already been made, (ii)
no  additional  Current Claims may be filed without court  approval,
and  (iii) Late Registrants are limited by the terms of the  Revised
Settlement Program.

The  company's current best estimate of the amount to cover the cost
and  expense  of  the Revised Settlement Program and  the  cost  and
expense   of  resolving  opt-out  claims  and  recovering  insurance
proceeds  is  $1.2  billion. After subtracting  payments  of  $1.159
billion  as of September 30, 2000, for defense and other  costs  and
settlements  with litigants and claimants, the company  had  accrued
liabilities of $41 million.

As  previously reported in the company's Annual Report on Form  10-K
for  the  year  ended  December  31, 1999,  the  company's  insurers
initiated  a declaratory judgment action in Ramsey County  Minnesota
against  the  company seeking adjudication of certain  coverage  and
allocation issues.   The  jury  trial finished on February 24, 2000.	

The jury returned a verdict favorable to the company by rejecting all of
the  insurers'  remaining defenses to coverage  for  breast  implant
liabilities  and costs. The court will consider additional  remedies
requested  by  the  company and the insurers including  eliminating,
limiting  or  extending  allocation  among  the  insurers  providing
occurrence-based  coverage  (before 1986),  pre-  and  post-judgment
interest, attorneys' fees and further equitable relief. The  court's
rulings in post verdict motions were rendered favorable to 3M.   The
court  awarded 3M prejudgment interest on amounts owing by  insurers
including  3M's reasonable attorney fees.  Entry of judgment  should
occur during the fourth quarter of 2000.

As  of September 30, 2000, the company had receivables for insurance
recoveries  of  $527 million, representing settled  but  yet  to  be
received  amounts  as  well as amounts contested  by  the  insurance
carriers. During the first nine months of 2000, the company received
payments from its occurrence carriers. Various factors could  affect
the timing and amount of proceeds to be received under the company's
various  insurance  policies, including (i) the timing  of  payments
made  in  settlement  of  claims; (ii)  the  outcome  of  occurrence
insurance litigation in the courts of Minnesota (as discussed above)
and  Texas;  (iii) potential arbitration with claims-made  insurers;
(iv)  delays  in  payment by insurers; and (v) the extent  to  which
insurers  may  become  insolvent in the  future.  There  can  be  no
absolute  assurance  that  the  company  will  collect  all  amounts
recorded as being probable of recovery from its insurers.

The   company's  current  estimate  of  the  probable   liabilities,
associated expenses and probable insurance recoveries related to the
breast  implant  claims  is  based on the  facts  and  circumstances
existing at this time. New developments may occur that could  affect
the   company's   estimates  of  probable   liabilities   (including
associated   expenses)  and  the  probable   amount   of   insurance
recoveries.  These developments include, but are not limited to, (i)
the  ultimate Fixed Amount Benefit distribution to claimants in  the
Revised  Settlement Program; (ii) the success of and  costs  to  the
company  in  defending  opt-out claims, including  claims  involving
breast  implants not manufactured or sold by the company; (iii)  the
outcome  of  the occurrence insurance litigation in  the  courts  of
Minnesota  and Texas; and (iv) the outcome of potential  arbitration
with claims-made insurers.

The   company  cannot  determine  the  impact  of  these   potential
developments  on  the  current  estimate  of  probable   liabilities
(including associated expenses) and the probable amount of insurance
recoveries.   Accordingly, the company is not able to  estimate  its
possible  future  liabilities  and  recoveries  beyond  the  current
estimates  of  probable amounts.  As new developments  occur,  these
estimates may be revised, or additional charges may be necessary  to
reflect the impact of these developments on the costs to the company
of   resolving  breast  implant  litigation,  claims  and  insurance
recoveries.   Such  revisions  or  additional  future  charges could
have a material adverse impact on the company's  net  income in the
quarterly period in which they are recorded.   Although the company
considers it unlikely, such revisions or additional future charges could	

also have a material adverse effect on  the  consolidated  financial
position,  annual  results  of operations,  or  cash  flows  of  the
company.

Environmental Matters

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

Under  certain  environmental  laws,  including  the  United  States
Comprehensive Environmental Response, Compensation and Liability Act
of  1980  and  similar state laws, the company may  be  jointly  and
severally  liable  for the costs of environmental  contamination  at
current or former facilities and at off-site locations at which  the
company has disposed of hazardous waste.  The company has identified
numerous locations, most of which are in the United States, at which
it  may  have some liability for remediating contamination.  Amounts
expensed  for environmental remediation activities are not  expected
to be material for the year 2000 at these locations. Liabilities for
estimated costs of environmental remediation are, depending  on  the
site,  based  primarily  upon internal or third-party  environmental
studies,  and  estimates as to the number, participation  level  and
financial  viability  of any other potentially responsible  parties,
the  extent of the contamination and the nature of required remedial
actions.  Recorded  liabilities are adjusted as further  information
develops  or  circumstances  change. The  amounts  provided  in  the
company's   consolidated  financial  statements  for   environmental
liabilities  are  the  gross  amount of  such  liabilities,  without
deductions  for  insurance  or  third party  indemnity  claims.  The
company  expects that the amounts accrued will be paid out over  the
periods  of remediation for the applicable sites, currently  ranging
from approximately 5 to 30 years.

It  is  often  difficult  to  estimate  the  cost  of  environmental
compliance   and   remediation  and  potential  claims   given   the
uncertainties  regarding  the  interpretation  and  enforcement   of
applicable  environmental  laws  and  regulations,  the  extent   of
environmental  contamination and the existence of alternate  cleanup
methods. The company records an environmental liability when  it  is
probable that a liability has been incurred by the company  and  the
amount  of  the  liability can be reasonably  estimated.   Where  no	

amount  within a range of estimates is more likely, the  minimum  is
recorded.  Otherwise,  the  most  likely  cost  to  be  incurred  is
recorded.

The  company's  current assessment of the probable  liabilities  and
associated expenses related to environmental matters is based on the
facts  and  circumstances known at this time. New  developments  may
occur that could affect the company's assessment. These developments
include,  but  are  not limited to, (i) changes in  the  information
available  regarding  the  environmental  impact  of  the  company's
operations  and products; (ii) changes in environmental  regulations
or  enforcement  policies;  (iii) new and  evolving  analytical  and
remediation  techniques;  (iv) success in  allocating  liability  to
other  potentially responsible parties; and (v) financial  viability
of   other   potentially   responsible   parties   and   third-party
indemnitors.

Although  the company believes that the amounts accrued for  current
environmental  liabilities  are adequate,  given  the  uncertainties
involved in environmental matters, it is possible that the amount of
capital  expenditures  and other costs which will  be  required  may
exceed  the  amounts accrued for environmental liabilities  and  the
difference  could have a material adverse effect on the consolidated
financial position, annual results of operations, or cash  flows  of
the company.
