OVERVIEW



3M is a diversified global manufacturer, technology innovator and marketer of a
wide variety of products and services. As more fully described in both the
Performance by Business Segment section in MD&A and in Note 19, effective in the
first quarter of 2020, the Company changed its business segment reporting in its
continuing effort to improve the alignment of businesses around markets and
customers. Additionally, the Company consolidated the way it presents geographic
area net sales by providing an aggregate Americas geographic region (combining
former United States and Latin America and Canada areas). Also, effective in the
second quarter of 2020, the measure of segment operating performance used by
3M's chief operating decision maker changed and, as a result, the Company's
disclosed measure of segment profit/loss has been updated. Business segment
information presented herein reflects the impact of these changes for all
periods presented.



3M manages its operations in four operating business segments: Safety and
Industrial; Transportation and Electronics; Health Care; and Consumer. From a
geographic perspective, any references to EMEA refer to Europe, Middle East

and
Africa on a combined basis.



Consideration of COVID-19:



3M is impacted by the global pandemic and related effects associated with the
coronavirus (COVID-19). The Company updated its risk factors with respect to
COVID-19, which can be found in Item 1A "Risk Factors" in this document.



Public and private sector policies and initiatives to reduce the transmission of
COVID-19, such as the imposition of travel restrictions and the adoption of
remote working, have impacted 3M's operations. 3M continues to work to protect
its employees and the public, maintain business continuity and sustain its
operations, including ensuring the safety and protection of people who work in
its plants and distribution centers across the world, many of whom support the
manufacturing and delivery of products that are critical in response to the
global pandemic. COVID-19 has impacted 3M's supply chains relative to global
demand for products like respirators, surgical masks and commercial cleaning
solutions. As this situation continues, 3M also closely monitors and responds to
potential impacts to the Company's broader supply chain associated with other
products. COVID-19 has also affected the ability of suppliers and vendors to
provide products and services to 3M. Furthermore, COVID-19 has impacted the
broader economies of affected countries, including negatively impacting economic
growth.The Company has taken steps to help employees lead safe and productive
lives during the outbreak including remote working; escalated procedures in
factories related to personal safety, cleaning and medical screening measures;
and pandemic leave policies. 3M closely monitors how the spread of COVID-19 is
affecting employees and business operations and has preparedness plans to help
protect the safety of employees around the world while safely continuing
business. While nearly all of our manufacturing locations and distribution
centers are fully or partially operational, the Company

                                       18

implemented plant and/or line shutdowns during 2020 related to certain markets
due to weaker customer demand or government mandates. Some of the above factors
have increased the demand for 3M products, while others have decreased demand or
made it more difficult for 3M to serve customers. Serving 3M customers is a
priority and teams continue to communicate with individual customers about
potential disruptions.



3M's total sales increased 0.1% for the full year 2020 when compared to 2019.
Organic local-currency sales decreased 1.7% for the full year 2020 when compared
to 2019. Given the diversity of 3M's businesses, the impact of COVID-19 varied
across the Company throughout 2020. 3M experienced strong sales growth in
personal safety, as well as in other areas such as home improvement, general
cleaning, semiconductor, data center, and biopharma filtration. COVID-related
respirator sales are estimated to have impacted year-on-year organic
local-currency sales growth by approximately 3 percent for the year ending
December 31, 2020. At the same time, weakness in several end markets, while
improving, contributed in part to sales declines in a number of 3M's businesses
with the biggest year-on-year total sales decreases in oral care (down 19
percent), advanced materials (down 17 percent), automotive and aerospace (down
16 percent), commercial solutions (down 14 percent), stationery and office (down
11 percent), closure and masking (down 11 percent), automotive aftermarket (down
10 percent), and businesses aligned to general industrial applications such as
abrasives (down 15 percent) and industrial adhesives and tapes (down 5 percent).



3M's operating income margins increased 3.1 percentage points year-on-year for
the year ending December 31, 2020. Factoring out the impact on operating income
of special items as described in the Certain amounts adjusted for special items
- (non-GAAP measures) section below, operating income margins increased 0.1
points to 21.3 percent for the year ending December 31, 2020 when compared to
2019. Various COVID-19 implications contributed in part to these results.



Overall, the impact of the COVID-19 pandemic on 3M's consolidated results of
operations was primarily driven by factors related to changes in demand for
products and disruption in global supply chains as described above. While it is
not feasible to identify or quantify all the other direct and indirect
implications on 3M's results of operations, below are factors that 3M believes
have also affected its 2020 results:



Factors contributing to charges:

? Period expenses of unabsorbed manufacturing costs and increased expected credit

losses on customer receivables.

Restructuring actions addressing structural enterprise costs and operations in

? certain end markets as a result of the COVID-19 pandemic and related economic

impact resulting in a second quarter 2020 charge of $58 million (as further

discussed in Note 5).

? Committed financial support to various COVID-relief and medical research

initiatives.

Charge of $22 million related to equity securities as discussed in the "Assets

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

section of Note 15 that use the measurement alternative described therein in

addition to an immaterial pre-tax charge related to impairment of certain

? indefinite lived tradenames in the first quarter of 2020. 3M continues to

regularly consider if COVID-19 and other related market implications could

indicate it is more likely than not the carrying amount of various applicable

assets may be impaired and assess whether certain investments without readily


   determinable fair values may have been impacted.



Factors providing benefits or other impacts:

Decreased discretionary spending in areas such as travel, professional

services, and advertising/merchandising as well as cost reduction efforts,

? hiring freezes, and maintaining only essential contract workers. 3M continues


   to monitor discretionary spending and deploy cost control efforts as the
   situation continues.

Government-sponsored COVID-response stimulus and relief initiatives, including

? certain employment retention benefits under the Coronavirus Aid, Relief and

Economic Security (CARES) Act in the United States.

? Lower self-insured medical visit/instance expense during 2020.

Instituted accelerated vacation usage policies which benefited the second

? quarter of 2020 year-on-year, but provided a penalty in comparison to prior


   year in the second half of 2020.




As previously disclosed, in light of circumstances, 3M took actions to ensure
sources of cash may remain strong, including the March 2020 issuance of $1.75
billion of registered notes, suspension of share repurchases, and the decrease
of its 2020 capital spending to approximately $1.5 billion. While capital
spending decreased, it included additional expansion of respirator production
capacity. 3M continues to have access to its commercial paper program and
undrawn committed credit facility. Refer to the Financial Condition and
Liquidity section below for more information on the Company's liquidity
position.

                                       19

  Table of Contents

The Company also continues to evaluate the extent to which it may avail itself
of various government-sponsored COVID-response stimulus, relief, and production
initiatives around the world, such as under the Defense Production Act (DPA) and
CARES Act in the United States. During 2020 and into January 2021, 3M reached
certain agreements with governments in the U.S. and other countries involving
just over $250 million of asset funding to expand capacity to supply N-95
respirators.



Due to the speed with which the COVID-19 situation is developing and evolving
and the uncertainty of its duration and the timing of recovery, 3M is not able
at this time to predict the extent to which the COVID-19 pandemic may have a
material effect on its consolidated results of operations or financial
condition.

Year 2020 EPS:



For year ended December 31, 2020, net income attributable to 3M was $5.384
billion, or $9.25 per diluted share basis, compared to $4.570 billion, or $7.81
per diluted share, for year ended December 31, 2019, an increase of 18.4 percent
on a per diluted share basis.



The Company refers to various "adjusted" amounts or measures on an "adjusted
basis". These exclude special items. These non-GAAP measures are further
described and reconciled to the most directly comparable GAAP financial measures
in the Certain amounts adjusted for special items - (non-GAAP measures) section
below.



On an adjusted basis, net income attributable to 3M was $5.088 billion, or $8.74
per diluted share for 2020 compared to $5.193 billion, or $8.88 per diluted
share in December 31, 2019, a decrease of 1.5 percent on a per diluted share
basis.


Additional discussion related to the components of the year-on-year change in earnings per diluted share follows:

Organic growth/productivity and other:

Lower organic volume growth in 2020 as a result of significant COVID-19 related

impacts, in addition to COVID-related net factors described in the preceding

? Overview-Consideration of COVID-19 section, decreased earnings per diluted

share year-on-year. 3M also experienced year-over-year increased costs as a


   result of the regular review of its respirator mask


                                       20

  Table of Contents

liabilities and certain follow-on accelerated depreciation following some of the

restructuring described below. Partially offsetting this net decrease in

earnings per share were year-on-year net gains related to certain property sales

(in 2020 within Safety and Industrial and in 2019 within Corporate and

Unallocated) in addition to benefits recognized in 2020 related to the

restructuring and other actions taken in 2019 (and the adjustments thereto in

2020) along with continued cost management and productivity efforts.

? On a combined basis, higher defined benefit pension and postretirement service

cost increased expense year-on-year.

Interest expense (net of interest income) increased in 2020, as a result of

higher U.S. average debt balances and lower year-on-year interest income driven

? by lower average interest rates on cash balances. 2020 interest expense also

included an early debt extinguishment charge in conjunction with the repayment


   of notes in December 2020.



Non divestiture-related restructuring actions:

3M recorded non divestiture-related restructuring pre-tax charges aggregating

$195 million in 2020. These included charges in the second quarter of 2020 to

address certain COVID-related impacts and in the fourth quarter as 3M initiated

? actions to further enhance its operational and marketing capabilities. In 2019,

charges included $282 million as the Company committed to actions in light of

slower than expected 2019 sales and associated with realigning its

organizational structure and operating model. See Note 5 for additional

details.

? The year-on-year impact of the non divestiture-related restructuring actions


   taken in 2020 and 2019 increased earnings per diluted share by 12 cents.




Acquisitions/divestitures:

Acquisition impacts, which are measured for the first twelve months

post-transaction, relate to the acquisitions of M*Modal (first quarter 2019),

and Acelity (fourth quarter 2019). These items collectively decreased earnings

? per diluted share by 7 year-on-year for 2020. The net impacts related to these

acquisitions included income from operations, more than offset by transaction

and integration costs. Financing costs related to these acquisitions is also

included.

Divestiture impacts include the lost operating income from divested businesses,

? which decreased earnings per diluted share by 3 cents year-on-year for 2020.

This was primarily related to the divestiture of the Company's drug delivery


   business.




Foreign exchange impacts:

Foreign currency impacts (net of hedging) decreased pre-tax earnings

? year-on-year by approximately $81 million in 2020, which decreased earnings per

diluted share by 11 cents, excluding the impact of foreign currency changes on


   tax rates.




Income tax rate:

Certain items above reflect specific income tax rates associated therewith.

? Overall, the effective tax rate for 2020 was 19.6 percent, a decrease of 0.2

percentage points versus 2019. On an adjusted basis (as discussed below), the

effective tax rate increased 0.1 percentage points year-on-year for 2020.

Factors that decreased the effective tax rate for 2020 included geographical

? income mix and adjustments to uncertain tax positions. These decreases were

partially offset by decreased benefit from stock options. Refer to Note 10 for


   additional details.



Shares of common stock outstanding:

Lower shares outstanding increased earnings per share year-on-year by 4 cents

per diluted share for 2020. Weighted-average diluted shares outstanding in 2020

declined 0.5 percent year-on-year, which benefited earnings per share. The

? decrease in the outstanding weighted-average diluted shares relates to the

Company's purchase of $368 million of its own stock, prior to suspension of

share repurchases under its board-approved stock repurchase program in late

March 2020 with other repurchase activity limited to 3M's stock compensation


   plans.




Year 2019 EPS:



Organic growth/productivity and other:

Negative organic local-currency sales growth as a result of softness in certain

end markets and channel inventory adjustments, along with actions taken by 3M

? in response to lower sales volumes and high inventory levels, which resulted in

lower manufacturing and inventory absorption, reduced earnings per diluted

share. Partially offsetting these impacts were benefits from restructuring

actions taken in the second quarter of 2019.




                                       21

  Table of Contents

? Defined benefit pension and postretirement service cost expense decreased

expense year-on-year, which benefited earnings per diluted share.

? Lower income related to non-service cost components of pension and

postretirement expense, increased expense year-on-year.

Interest expense (net of interest income) increased in 2019, as a result of

higher U.S. average debt balances, partially offset by the increase in interest

? income driven by higher balances in cash, cash equivalents and marketable

securities during the year resulting from the proceeds from debt issuances in


   advance of the October 2019 Acelity acquisition.



Non divestiture-related restructuring actions:

During the second quarter of 2019, in light of slower than expected 2019 sales,

and additionally in the fourth quarter to realign 3M's organizational structure

? and operating model, management approved and committed to undertake certain

restructuring actions. In aggregate, the Company recorded a full year 2019

combined pre-tax charge of $282 million, or 41 cents per diluted share. See


   Note 5 for additional details.




Acquisitions/divestitures:

Acquisition impacts, which are measured for the first twelve months

post-transaction, relate to the acquisitions of M*Modal (first quarter 2019),

and Acelity (fourth quarter 2019). These items collectively decreased earnings

per diluted share by 19 cents year-on-year for 2019. The net impacts related to

? these acquisitions included income from operations, more than offset by

transaction and integration costs. Interest expense related to financing costs

of these acquisitions is also included. Expenses related to the October 2019

acquisition of Acelity also include financing costs and the tax effect of

repatriating funds in advance of the close of the acquisition.

Divestiture impacts collectively decreased earnings per diluted share by 5

cents year-on-year for 2019. They include remaining stranded costs and lost

operating income related to the 2018 divestiture of the Communication Markets

? Division, which decreased earnings per diluted share by 4 cents year-on-year,

and lost operating income from other divested businesses (primarily the

Company's gas and flame detection business), which decreased earnings per


   diluted share by 1 cent year-on-year.




Foreign exchange impacts:

? Foreign currency impacts (net of hedging) were essentially flat year-on-year,


   excluding the impact of foreign currency changes on tax rates.




Income tax rate:

Certain items above reflect specific income tax rates associated therewith.

? Overall, the effective tax rate for 2019 was 19.8 percent, a decrease of 3.6

percentage points versus 2018. On an adjusted basis (as discussed below), the

effective tax rate increased 0.2 percentage points year-on-year for 2019.

Factors that decreased the effective tax rate on a GAAP basis for 2019 included

prior year measurement period adjustments related to 2017 Tax Cuts and Jobs Act

(TCJA), prior year resolution of the NRD lawsuit (as described in Note 16) and

? geographical income mix. These decreases were partially offset by the

deconsolidation of the Venezuelan subsidiary, adjustments to uncertain tax

positions, and significant litigation-related charges. Refer to Note 10 for


   additional details.



Shares of common stock outstanding:

Lower shares outstanding increased earnings per share year-on-year by 22 cents

per diluted share for 2019. Weighted-average diluted shares outstanding in 2019

? declined 2.8 percent year-on-year which benefited earnings per share. The

decrease in the outstanding weighted-average diluted shares relates to the


   Company's purchase of $1.4 billion of its own stock in 2019.






                                       22

Certain amounts adjusted for special items - (non-GAAP measures):





In addition to reporting financial results in accordance with U.S. GAAP, the
Company also provides non-GAAP measures that adjust for the impacts of special
items. For the periods presented, special items include the items described
below. Beginning in 2020, the Company includes gain/loss on sale of businesses
and divestiture-related restructuring actions as special items due to their
potential distortion of underlying operating results. Information provided
herein reflects the impact of this change for all periods presented. Operating
income (measure of segment operating performance), income before taxes, net
income, earnings per share, and the effective tax rate are all measures for
which 3M provides the reported GAAP measure and a measure adjusted for special
items. The adjusted measures are not in accordance with, nor are they a
substitute for, GAAP measures. The Company considers these non-GAAP measures in
evaluating and managing the Company's operations. The Company believes that
discussion of results adjusted for these items is meaningful to investors as it
provides a useful analysis of ongoing underlying operating trends. The
determination of these items may not be comparable to similarly titled measures
used by other companies. Special items include:



Significant litigation-related charges/benefits:

In 2020, 3M recorded a net pre-tax charge of $17 million ($13 million after

tax) related to PFAS (certain perfluorinated compounds) matters. The charge was

more than offset by a reduction in tax expense of $52 million related to

? resolution of tax treatment with authorities regarding the previously disclosed

2018 agreement reached with the State of Minnesota that resolved the Natural

Resources Damages lawsuit. These items, in aggregate, resulted in a $39 million

after tax benefit.

In 2019, the Company recorded significant litigation-related charges of $762

million ($590 million after tax) related to PFAS matters and coal mine dust

? respirator mask lawsuits of which $214 million ($166 million after tax)

occurred in the fourth quarter. The aggregate 2019 pre-tax charge was reflected

in cost of sales ($328 million) and selling, general and administrative expense

($434 million). These charges are further discussed in Note 16.

In 2018, the Company recorded significant litigation-related charges of $897

million ($770 million after tax) for PFAS matters related to the previously

? disclosed agreement reached with the State of Minnesota that resolved the

Natural Resource Damages lawsuit. Essentially all of the aggregate 2018 pre-tax


   charge was reflected in selling, general and administrative expense.



Gain/loss on sale of businesses:

In the first quarter of 2020, 3M recorded a pre-tax gain of $2 million ($1

million loss after tax) related to the sale of its advanced

? ballistic-protection business and recognition of certain contingent

consideration. In the second quarter of 2020, 3M recorded a pre-tax gain of

$387 million ($304 million after tax) related to the sale of its drug delivery

business. Refer to Note 3 for further details.

In the first quarter of 2019, 3M recorded a gain related to the sale of certain

oral care technology comprising a business in addition to reflecting an earnout

on a previous divestiture, which together resulted in a net gain of $8 million

($7 million after tax). In the second quarter of 2019, as a result of a "held

for sale" tax benefit related to the legal entities associated with the pending

? divestiture of the Company's gas and flame detection business, 3M recorded an

after-tax gain of $43 million. In the third quarter of 2019, 3M recorded a gain

related to the divestiture of the Company's gas and flame detection business

and an immaterial impact as a result of measuring a disposal group at the lower

of its carrying amount or fair value less cost to sell, which in aggregate

resulted in a pre-tax gain of $106 million ($79 million after tax).

In the first quarter of 2018, 3M recorded a gain related to the sale of certain

personal safety product offerings primarily focused on noise, environmental,

and heat stress monitoring, the sale of its polymer additives compounding

business, and a gain on final closing adjustments from a prior divestiture

which, in aggregate, resulted in a net pre-tax gain of $24 million ($19 million

? after tax). In the second quarter of 2018, 3M recorded a pre-tax gain of $12

million ($10 million after tax) related to the sale of its abrasive glass

products business. In the fourth quarter of 2018, 3M recorded a gain of $2

million related to an earnout from a previous divestiture. Additionally, in

2018, 3M completed the sale of substantially all of its Communication Markets

Division and reflected a pre-tax gain of $509 million ($410 million after tax).

Divestiture-related restructuring actions:

In the second quarter 2020, following the divestiture of substantially all of

the drug delivery business (see Note 3) management approved and committed to

undertake certain restructuring actions addressing corporate functional costs

? and manufacturing footprint across 3M in relation to the magnitude of amounts

previously allocated/burdened to the divested business. As a result, 3M

recorded a second quarter 2020 pre-tax charge of $55 million ($46 million after


   tax) and made a subsequent immaterial adjustment thereto. Refer to Note 5 for
   further details.


                                       23

  Table of Contents

During 2018, management approved and committed to undertake certain

restructuring actions as further described in Note 5, related to addressing

? corporate functional costs following the Communication Markets Division

divestiture resulting in a 2018 pre-tax charge of $127 million ($110 million

after tax), net of adjustments for reductions in cost estimates of $10 million.

Loss on deconsolidation of Venezuelan subsidiary:

In the second quarter of 2019, 3M recorded a pre-tax charge of $162 million

? related to the deconsolidation of the Company's Venezuelan subsidiary as

further discussed in Note 1.

Measurement period accounting for TCJA:

3M recorded a net tax expense of $176 million in 2018 as a measurement period

Additional information beyond what is included in the preceding table is as follows:

In the Americas geographic area, U.S. total sales increased 2 percent and

organic-local currency decreased 1 percent. Total sales remained flat in

Mexico, as organic local-currency sales increases of 1 percent were partially

? offset by lost sales from divested businesses and foreign currency translation

impacts. In Canada, total sales and organic local currency increased 3 percent.

In Brazil, total sales decreased 4 percent, as organic local-currency sales


   growth of 3 percent was more than offset by foreign currency translation
   impacts.

In the Asia Pacific geographic area, China total sales decreased 7 percent and

? organic local-currency sales decreased 4 percent. In Japan, total sales

decreased 2 percent and organic local currency sales decreased 3 percent.






Foreign currency translation decreased year-on-year sales by 1.7 percent, while
selling prices increased by 0.6 percent year-on-year for 2019, with price growth
in EMEA and Americas, while Asia Pacific was flat.



Managing currency risks:



The stronger U.S. dollar had a negative impact on sales in full year 2020
compared to the same period last year. Net of the Company's hedging strategy,
foreign currency negatively impacted earnings for full year 2020 compared to the
same period last year. 3M utilizes a number of tools to hedge currency risk
related to earnings. 3M uses natural hedges such as pricing, productivity, hard
currency and hard currency-indexed billings, and localizing source of supply. 3M
also uses financial hedges to mitigate currency risk. In the case of more liquid
currencies, 3M hedges a portion of its aggregate exposure, using a 12, 24 or 36
month horizon, depending on the currency in question. For less liquid
currencies, financial hedging is frequently more expensive with more limitations
on tenor. Thus, this risk is largely managed via local operational actions using
natural hedging tools as discussed above. In either case, 3M's hedging approach
is

                                       27

  Table of Contents

designed to mitigate a portion of foreign currency risk and reduce volatility, ultimately allowing time for 3M's businesses to respond to changes in the marketplace.





Financial condition:



3M generated $8.1 billion of operating cash flow in 2020, an increase of $1.0
billion when compared to 2019. This increase was primarily due to cost saving
actions taken in response to COVID-19 and lower year-on-year significant
litigation-related charges and the timing of associated payments. This followed
an operating cash flow increase of $631 million when comparing 2019 to 2018.
Refer to the section entitled "Financial Condition and Liquidity" later in MD&A
for a discussion of items impacting cash flows.



In November 2018, 3M's Board of Directors replaced the Company's February 2016
repurchase program with a new repurchase program. This new program authorizes
the repurchase of up to $10 billion of 3M's outstanding common stock, with no
pre-established end date. In 2020, the Company purchased $0.4 billion of its own
stock, compared to purchases of $1.4 billion in 2019. As of December 31, 2020,
approximately $7.8 billion remained available under the authorization. In the
first quarter of 2020, the Company suspended repurchases under its
board-approved share repurchase program with other repurchase activity limited
to 3M's stock compensation plans. The Company plans to resume share purchases in
2021. In February 2021, 3M's Board of Directors declared a first-quarter 2021
dividend of $1.48 per share, an increase of 1 percent. This marked the 63rd
consecutive year of dividend increases for 3M.



Raw materials:



In 2020, the coronavirus (COVID-19) pandemic caused fluctuations in supply
markets. Generally, as demand for certain COVID-related products surged, 3M saw
a corresponding tightening in supply and some degree of price inflation in
associated markets. Within the supply chain of less essential products, 3M
experienced raw material price deflation as economies slowed and certain
producers scaled back or idled operations. Conversely, as markets re-opened and
demand increased, the Company experienced raw material price inflation with some
level of stabilization late in the year.



In response, the Company continued to deploy productivity projects to minimize
the impact of raw material inflation and market supply challenges, including
input management, reformulations, and multi-sourcing activities. Overall, on a
consolidated basis, 3M experienced net raw material deflation in 2020. To date,
the Company is receiving sufficient quantities of all raw materials to meet its
reasonably foreseeable production requirements. It is difficult to predict
future shortages of raw materials or the impact any such shortages would have.
3M has avoided disruption to its manufacturing operations through careful
management of existing raw material inventories, strategic relationships with
key suppliers, and development as well as qualification of additional supply
sources. 3M manages spend category price risks through negotiated supply
contracts and price protection agreements. In addition, 3M evaluates suppliers'
conformance with environmental and social compliance requirements.



Pension and postretirement defined benefit/contribution plans:


On a worldwide basis, 3M's pension and postretirement plans were 87 percent
funded at year-end 2020. The primary U.S. qualified pension plan, which is
approximately 67 percent of the worldwide pension obligation, was 91 percent
funded and the international pension plans were 93 percent funded. The U.S.
non-qualified pension plan is not funded due to tax considerations and other
factors. Asset returns in 2020 for the primary U.S. qualified pension plan were
13.6%, as 3M strategically invests in both growth assets and fixed income
matching assets to manage its funded status. For the primary U.S. qualified
pension plan, the expected long-term rate of return on an annualized basis for
2021 is 6.50%. The primary U.S. qualified pension plan year-end 2020 discount
rate was 2.55%, down 0.70 percentage points from the year-end 2019 discount rate
of 3.25%. The decrease in U.S. discount rates resulted in an increased valuation
of the projected benefit obligation (PBO). The primary U.S. qualified pension
plan's funded status decreased 1 percentage point in 2020 due to the higher PBO
resulting from the discount rate decrease and partially offset by higher return
on assets. Additional detail and discussion of international plan asset returns
and discount rates is provided in Note 13 (Pension and Postretirement Benefit
Plans).



3M expects to contribute approximately $100 million to $200 million of cash to
its global defined benefit pension and postretirement plans in 2021. The Company
does not have a required minimum cash pension contribution obligation for its
U.S. plans in 2021. 3M expects global defined benefit pension and postretirement
expense in 2021 to decrease by approximately $40 million pre-tax when

                                       28

compared to 2020. Refer to "Critical Accounting Estimates" within MD&A and Note 13 (Pension and Postretirement Benefit Plans) for additional information concerning 3M's pension and post-retirement plans.

Operating income margins increased year over year for 2020. The increase from
2019 to 2020 was primarily driven by lower significant litigation-related
charges and higher gains on divestitures (net of divestiture-related
restructuring actions) year-on-year. These items are further described in the
Certain amounts adjusted for special items - (non-GAAP measures) section above.
A number of factors impact the various income statement line items. Expanded
discussion of each of the income statement line items follows in the various
sections below.


In 2020 the Company's operating expenses were impacted by factors described in the preceding Overview - Consideration of COVID-19 section above.





In 2020 and 2019, 3M approved and committed to certain restructuring actions
that impacted cost of sales, SG&A, and R&D (see Note 5 for additional details).
In addition to actions related to divestitures (as discussed earlier in the
Certain amounts adjusted for special items - (non-GAAP measures) section), for
2020 these included charges to address certain COVID-related impacts and actions
to further enhance its operational and marketing capabilities. In 2019, charges
included actions in light of slower than expected 2019 sales and associated with
realigning its organizational structure and operating model.



Pension and postretirement service cost expense is recorded in cost of sales,
SG&A, and R&D. In total, 3M's defined benefit pension and postretirement service
cost expense increased $31 million in 2020. Refer to Note 13 (Pension and
Postretirement Plans) for the service cost components of net periodic benefit
costs.



The Company is investing in an initiative called business transformation, with
these investments impacting cost of sales, SG&A, and R&D. Business
transformation encompasses the ongoing multi-year phased implementation of an
enterprise resource planning (ERP) system on a worldwide basis, as well as
changes in processes and internal/external service delivery across 3M.



Cost of Sales:


Cost of sales includes manufacturing, engineering and freight costs.





Cost of sales, measured as a percent of sales, decreased during 2020 when
compared to 2019. Decreases were related to lower significant litigation-related
charges taken in 2020, which were partially offset by 2020 COVID-related net
impacts, including period expenses of unabsorbed manufacturing costs, in
addition to higher restructuring action charges taken in 2020 along with certain
related follow-on accelerated depreciation. In addition, selling prices
increased year-on-year by 0.6 percent for full year 2020, and lower raw material
costs reduced cost of sales as a percentage of sales.





                                       29

  Table of Contents

Selling, General and Administrative Expenses:





SG&A in dollars decreased slightly in 2020 when compared to 2019. The decrease
was driven by cost saving actions taken in response to COVID-19, in addition to
benefits from prior year restructuring (and adjustments thereto in 2020).
Additional factors that decreased SG&A in 2020 also include lower year-on-year
impact related to significant litigation-related charges. In terms of SG&A as a
percent of sales, partially offsetting these decreases was the overall effect of
the COVID-19 pandemic on sales that resulted in higher costs as a percent of
sales. SG&A was also impacted by increased spending year-on-year related to
Acelity, which was acquired in the fourth quarter of 2019.



Research, Development and Related Expenses:





R&D in dollars decreased slightly in 2020 when compared to 2019 and remained
relatively consistent as a percent of sales at 5.8% in 2020 compared to 5.9% in
2019. 3M continued to invest in its key initiatives, including R&D aimed at
disruptive innovation programs with the potential to create entirely new markets
and disrupt existing markets. Incremental R&D spending in 2020 included
activities related to the Acelity business acquired in the fourth quarter of
2019. 3M also experienced lower year-on-year restructuring activities impacting
R&D.



Gain on Sale of Businesses:



During the first quarter of 2020, the Company recorded a pre-tax gain of $2
million ($1 million loss after tax) related to the sale of its advanced
ballistic-protection business and recognition of certain contingent
consideration. During the second quarter of 2020, the Company recorded a pre-tax
gain of $387 million ($304 after tax) related to the sale of substantially all
of its drug delivery business.



During the first quarter of 2019, the Company sold certain oral care technology
comprising a business and reflected an earnout on a previous divestiture
resulting in a pre-tax gain of $8 million ($7 million gain after tax). In the
third quarter of 2019, 3M recorded a gain related to the divestiture of the
Company's gas and flame detection business and an immaterial impact as a result
of measuring a disposal group at the lower of its carrying amount or fair value
less cost to sell, which in aggregate resulted in a pre-tax gain of $106 million
($79 million after tax). Refer to Note 3 for additional details on divestitures.



Operating Income Margin:


3M uses operating income as one of its primary business segment performance measurement tools. Refer to the table below for a reconciliation of operating income margins for 2020 and 2019.






                                                             Year ended December 31,

  Table of Contents



Year 2020 operating income:



Operating income margins increased 3.1 percentage points in 2020 when compared
to 2019. Factoring out the impact on operating income of special items as
described in the Certain amounts adjusted for special items - (non-GAAP
measures) section above, operating margins increased 0.1 percentage points to
21.3 percent in 2020 when compared to 2019.



Additional discussion related to the components of the year-on-year change in operating income margins follows:

Organic volume/productivity and other:

Lower organic volume growth in 2020 as a result of significant COVID-19 related

impacts, in addition to COVID-related net factors described in the preceding

Overview-Consideration of COVID-19 section, decreased operating income margins

year-on-year. 3M also experienced year-over-year increased costs as a result of

the regular review of its respirator mask liabilities and certain follow-on

? accelerated depreciation following some of the restructuring described below.

Partially offsetting this net decrease were year-on-year net gains related to

certain property sales (in 2020 with Safety and Industrial and in 2019 within

Corporate and Unallocated) in addition to benefits recognized in 2020 related

to the restructuring and other actions taken in 2019 (and the adjustments

thereto in 2020) along with continued cost management and productivity efforts.

? Operating income margins decreased year-on-year due to higher defined benefit


   pension and postretirement service cost expense.



Non divestiture-related restructuring actions:

3M recorded non divestiture-related restructuring charges that impacted

operating income aggregating $195 million in 2020. These included charges in

the second quarter of 2020 to address certain COVID-related impacts and in the

fourth quarter as 3M initiated actions to further enhance its operational and

? marketing capabilities. In 2019, charges included $246 million impacting

operating income (and $36 million impacting other expense (income)) as the

Company committed to actions in light of slower than expected 2019 sales and

associated with realigning its organizational structure and operating model.

See Note 5 for additional details.

? The year-on-year impact of the non divestiture-related restructuring charges


   taken in 2020 and 2019 increased operating income margins.




Acquisitions/divestitures:

? Acquisition-related impacts relate to the ongoing integration of M*Modal and

Acelity, which decreased operating income margins year-on-year.

? Divestiture impacts, which includes lost operating income from divested

businesses, increased operating income margins year-on-year.

Selling price and raw material impact:

? Higher selling prices in addition to lower raw material cost impacts benefited


   operating income margins year-on-year for 2020.




Foreign exchange impacts:

? Foreign currency effects (net of hedge gains) decreased operating income


   margins year-on-year.



Significant litigation-related charges:

Operating income margins for 2020 and 2019 included the $17 million and $762

? million impact, respectively, of significant litigation-related charges (as

discussed earlier in the Certain amounts adjusted for special items - (non-GAAP


   measures) section).



Gain/loss on sale of businesses:

2020 and 2019 included gains of $389 million and $114 million, respectively, on

? sale of businesses. See the Certain amounts adjusted for special items

- (non-GAAP measures) section for more information.






                                       31

  Table of Contents

Divestiture-related restructuring actions:

Operating income margins for full year 2020 included the $55 million second

quarter impact as a result of certain restructuring actions following the

divestiture of substantially all of the drug delivery business addressing

? corporate functional costs and manufacturing footprint across 3M in relation to

the magnitude of amounts previously allocated/burdened to the divested

business. Refer to Note 5 for further details. This item was also discussed

earlier in the Certain amounts adjusted for special items - (non-GAAP measures)


   section.




Year 2019 operating income:



Operating income margins decreased 2.8 percentage points for the full year 2019
when compared to full year 2018. Factoring out the impact on operating income of
special items as described in the Certain amounts adjusted for special items -
(non-GAAP measures) section above, operating margins decreased 2.3 percentage
points to 21.2 percent in 2019 when compared to 2018.



Organic volume/productivity and other:

Negative organic local sales volume growth as a result of softness in certain

end markets and channel inventory adjustments, along with actions taken by 3M

? in response to lower sales volumes and high inventory levels, which resulted in

lower manufacturing and inventory absorption, reduced operating margins.

Partially offsetting these impacts were benefits from restructuring actions

taken in the second quarter of 2019.

? Operating income margins increased year-on-year due to lower defined benefit


   pension and postretirement service cost expense.



Non divestiture-related restructuring actions:

During the second quarter of 2019, in light of slower than expected 2019 sales,

and additionally in the fourth quarter to realign 3M's organizational structure

? and operating model, management approved and committed to undertake certain

restructuring actions. The resulting charges included $246 million impacting

operating income (and $36 million impacting other expense (income)). See Note 5


   for additional details.




Acquisitions/divestitures:

? Acquisition-related impacts relate to the on-going integration of M*Modal and

Acelity, which decreased operating income margins year-on-year.

Divestiture impacts include the lost operating income from divested businesses,

? which increased operating income margins year-on-year and primarily relate to

the divestiture of the Communication Markets Division.

? Remaining stranded costs from the 2018 divestiture of the Communication Markets


   Division also reduced operating margins year-on-year.



Selling price and raw material impact:

? Higher selling prices, partially offset by raw material cost increases,

benefited operating income margins year-on-year for 2019.






Foreign exchange impacts:

? Foreign currency effects (net of hedge gains) increased operating income


   margins year-on-year.



Significant litigation-related charges:

Operating income margins for 2018 and 2019 included the $897 million and $762

? million impact, respectively, of significant litigation-related charges (as

discussed earlier in the Certain amounts adjusted special items - (non-GAAP


   measures) section.




Other Expense (Income), Net:



See Note 6 for a detailed breakout of this line item.


The decrease in other expense (income) during 2020 was primarily due to the 2019
impact of deconsolidation of the Company's Venezuelan subsidiary. Refer to

Note
1 for additional details.



                                       32

  Table of Contents

Interest expense (net of interest income) increased during 2020 and 2019. The
increase in 2020 was due to higher U.S. average debt balances and lower
year-on-year interest income driven by lower average interest rates on cash
balances. 2020 interest expense also included an early debt extinguishment
charge in conjunction with the repayment of notes in December 2020. The increase
in 2019 was driven by higher U.S. average debt balances, partially offset by the
year-on-year increase in interest income driven by higher balances in cash, cash
equivalents and marketable securities during the year resulting from the
proceeds from debt issuances in advance of the October 2019 Acelity acquisition.



In addition, other expense (income) was impacted by lower year-on-year pension
and postretirement net periodic benefit non-service benefits for 2020 and 2019,
respectively. The lower year-on-year benefit in 2020 was primarily due to the
increased expense from lower December 31, 2019 discount rates. The decreases in
2019 was primarily due to the charge associated with the voluntary retirement
program taken in the second quarter of 2019 in addition to the pension
settlement charges in the fourth quarter of 2019 related to employee
retirements. Refer to Note 13 for additional details.



Provision for Income Taxes:

Effective tax rate            19.6 %  19.8 %




The effective tax rate for 2020 was 19.6 percent, a decrease of 0.2 percentage

compared to 23.4 percent in 2018, a decrease of 3.6 percentage points. Factors
that impacted the tax rates between years are further discussed in the Overview
section above and in Note 10.


3M currently estimates its effective tax rate for 2021 will be approximately 20 to 21 percent.





The tax rate can vary from quarter to quarter due to discrete items, such as the
settlement of income tax audits, changes in tax laws, and employee share-based
payment accounting; as well as recurring factors, such as the geographic mix of
income before taxes.


Refer to Note 10 for further discussion of income taxes.

Income from Unconsolidated Subsidiaries, Net of Taxes:

Income (loss) from unconsolidated subsidiaries, net of taxes $ (5) $


 -




Income (loss) from unconsolidated subsidiaries, net of taxes, is primarily
attributable to the Company's ownership interest in Kindeva using the equity
method of accounting following 3M's divestiture of the drug delivery business in
2020. See Note 3 for further discussion.



Net Income Attributable to Noncontrolling Interest:






(Millions)                                                  2020     2019
Net income (loss) attributable to noncontrolling interest   $   4    $  12

Net income (loss) attributable to noncontrolling interest represents the elimination of the income or loss attributable to non-3M ownership interests in 3M consolidated entities. The primary noncontrolling interest relates to 3M India Limited, of which 3M's effective ownership is 75 percent.





Currency Effects:



3M estimates that year-on-year currency effects, including hedging impacts,
decreased pre-tax income by $81 million in 2020 and increased pre-tax income by
$1 million in 2019. 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
foreign currency transaction effects, including hedging impacts, decreased
pre-tax income by approximately $21 million in 2020 and increased pre-tax income
by approximately $201 million in 2019. These estimates include transaction

gains
and

losses, including derivative instruments designed to reduce foreign currency
exchange rate risks. Refer to Note 14 in the Consolidated Financial Statements
for additional information concerning 3M's hedging activities.



PERFORMANCE BY BUSINESS SEGMENT


Item 1, Business Segments, provides an overview of 3M's business segments. In
addition, disclosures relating to 3M's business segments are provided in Note
19. Effective in the first quarter of 2020, the Company changed its business
segment reporting in its continuing effort to improve the alignment of
businesses around markets. Also, effective in the second quarter of 2020, the
measure of segment operating performance used by 3M's chief operating decision
maker (CODM) changed and, as a result, 3M's disclosed measure of segment
profit/loss (business segment operating income) has been updated for all periods
presented. The change to business segment operating income aligns with the
update to how the CODM assesses performance and allocates resources for the
Company's business segments.



As discussed in Note 19, 3M discloses business segment operating income as its
measure of segment profit/loss, reconciled to both total 3M operating income and
income before taxes. Business segment operating income includes dual credit for
certain related operating income (as described below in "Elimination of Dual
Credit"). Business segment operating income excludes certain expenses and income
that are not allocated to business segments (as described below in "Corporate
and Unallocated"). Additionally, the following special items are excluded from
business segment operating income and, instead, are included within Corporate
and Unallocated: significant litigation-related charges/benefits, gain/loss on
sale of businesses, and divestiture-related restructuring actions.



Information provided herein reflects the impact of these changes for all periods
presented. 3M manages its operations in four business segments. The reportable
segments are Safety and Industrial; Transportation and Electronics; Health

Care;
and Consumer.



Corporate and Unallocated:



In addition to these four business segments, 3M assigns certain costs to
"Corporate and Unallocated," which is presented separately in the preceding
business segments table and in Note 19. Corporate and Unallocated includes a
variety of miscellaneous items, such as corporate investment gains and losses,
certain derivative gains and losses, certain insurance-related gains and losses,
certain litigation and environmental expenses, corporate restructuring charges
and certain under- or over-absorbed costs (e.g. pension, stock-based
compensation) that the Company determines not to allocate directly to its
business segments. Additionally, Corporate and Unallocated operating income
includes special items such as significant litigation-related charges/benefits,
gain/loss on sale of businesses, and divestiture-related restructuring costs.
Corporate and Unallocated also includes sales, costs, and income from contract
manufacturing, transition services and other arrangements with the acquirer of
the Communication Markets Division following its 2018 divestiture through 2019
and the acquirer of the former drug delivery business following its 2020
divestiture. Because this category includes a variety of miscellaneous items, it
is subject to fluctuation on a quarterly and annual basis.



Corporate and Unallocated net operating loss decreased by $767 million in 2020 when compared to 2019.





Special Items

Refer to the Certain amounts adjusted for special items - (non-GAAP measures)
section and Note 5 for additional details on the impact of significant
litigation-related charges/benefits, gain/loss on sale of businesses, and
divestiture-related restructuring actions that are reflected in Corporate and
Unallocated.



Other Corporate Expense - Net

Other corporate operating expenses increased in 2020. The increases were due to
year-over-year increased net costs as a result of the regular review of 3M's
respirator mask liabilities, lower year-on-year gains from certain property
sales reflected in Corporate and Unallocated, in addition to transition service
and other arrangement costs, net of income, post-divestiture of the Company's
former drug delivery business in 2020, and increased legal expenses. These
increases were partially offset by lower year-on-year non divestiture-related
restructuring costs reflected in Corporate and Unallocated.

growth across most of the Company's general industrial-related portfolio.






Divestitures:

2018 divestitures that impacted 2019 results relate to the sale of certain

? personal safety product offerings primarily focused on noise, environmental,

and heat stress monitoring (first quarter 2018), and it's abrasives glass

products business (second quarter of 2018).

? Also in 2018, 3M completed the sale of substantially all of its Communication

Markets Division.

PERFORMANCE BY GEOGRAPHIC AREA


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
generally 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. As customers move their operations from one geographic area to
another, 3M's results will follow. Thus, net sales in a particular geographic
area are not indicative of end-user consumption in that geographic area.
Financial information related to 3M operations in various geographic areas is
provided in Note 2 and Note 19.

divestitures and other actions.



Capital Spending/Net Property, Plant and Equipment:





Investments in property, plant and equipment enable growth across many diverse
markets, helping to meet product demand and increasing manufacturing efficiency.
In 2020, 63 percent of 3M's capital spending was within the Americas, followed
by Europe, Middle East and Africa, and Asia Pacific. 3M is increasing its
investment in manufacturing and sourcing capability in order to more closely
align its product capability with its sales in major geographic areas in order
to best serve its customers throughout the world with proprietary, automated,
efficient, safe and sustainable processes. Capital spending is discussed in more

Activities."





CRITICAL ACCOUNTING ESTIMATES



Information regarding significant accounting policies is included in Note 1 of
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 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, pension and postretirement obligations, goodwill and certain long-lived assets, and uncertainty in income tax positions. 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:



Assessments of lawsuits and claims can involve a series of complex judgments
about future events and can rely heavily on estimates and assumptions. The
Company accrues an estimated liability for legal proceeding claims that are both
probable and estimable in accordance with Accounting Standard Codification (ASC)
450, Contingencies. Please refer to the section entitled "Process for Disclosure
and Recording of Liabilities Related to Legal Proceedings" (contained in "Legal
Proceedings" in Note 16) for additional information about such estimates.



Pension and Postretirement Obligations:

The Company makes certain estimates and judgements in relation to its defined benefit pension and postretirement obligations.





The benefit obligation represents the present value of the benefits that
employees are entitled to in the future for services already rendered as of the
measurement date. The Company measures the present value of these future
benefits by projecting benefit payment cash flows for each future period and
discounting these cash flows back to the December 31 measurement date, using the
yields of a

                                       40

  Table of Contents

portfolio of high quality, fixed-income debt instruments that would produce cash
flows sufficient in timing and amount to settle projected future benefits.
Service cost and interest cost are measured separately using the spot yield
curve approach applied to each corresponding obligation. Service costs are
determined based on duration-specific spot rates applied to the service cost
cash flows. The interest cost calculation is determined by applying
duration-specific spot rates to the year-by-year projected benefit payments. The
spot yield curve approach does not affect the measurement of the total benefit
obligations as the change in service and interest costs offset in the actuarial
gains and losses recorded in other comprehensive income.



Using this methodology, the Company determined discount rates for its plans as
follow:


                                                                International

December 31, 2020 Liability:

2021 Net Periodic Benefit Cost Components:
Service cost                                            2.84 %           1.23 %            2.71 %
Interest cost                                           1.93 %           1.13 %            1.68 %




Another significant element in determining the Company's pension expense is the
expected return on plan assets. The expected return on plan assets for the
primary U.S. qualified pension plan is based on strategic asset allocation of
the plan, long-term capital market return expectations, and expected performance
from active investment management. For the primary U.S. qualified pension plan,
the expected long-term rate of return on an annualized basis for 2021 is 6.50%,
a decrease from 6.75% in 2020. Return on assets assumptions for international
pension and other post-retirement benefit plans are calculated on a plan-by-plan
basis using plan asset allocations and expected long-term rate of return
assumptions. The weighted average expected return for the international pension
plans is 4.36% for 2021 compared to 4.70% for 2020. Refer to Note 13 for
information on how the 2020 rates were determined.



3M follows ASC 820, Fair Value Measurements and Disclosures in determining the
fair value of plan assets within the Company's pension and postretirement
benefit plans. While the Company believes the valuation methods used to
determine the fair value of plan assets are appropriate and consistent with
other market participants, the use of different methodologies or assumptions to
determine the fair value of certain financial instruments could result in a
different estimate of fair value at the reporting date. See Note 13 for
additional discussion of actuarial assumptions used in determining defined
benefit pension and postretirement health care liabilities and expenses.



For the year ended December 31, 2020, the Company recognized consolidated
defined benefit pre-tax pension and postretirement service cost expense of $456
million and a benefit of $50 million related to all non-service pension and
postretirement net benefit costs (after settlements, curtailments, special
termination benefits and other) for a total consolidated defined benefit pre-tax
pension and postretirement expense of $406 million, up from $357 million in
2019.



In 2021, defined benefit pension and postretirement service cost expense is
anticipated to total approximately $497 million while non-service pension and
postretirement net benefit costs is anticipated to be a benefit of approximately
$130 million, for a total consolidated defined benefit pre-tax pension and
postretirement expense of $367 million, a decrease of approximately $40 million
compared to 2020.



The table below summarizes the impact on 2021 pension expense for the U.S. and
international pension plans of a 0.25 percentage point increase/decrease in the
expected long-term rate of return on plan assets and discount rate assumptions
used to measure plan liabilities and 2020 net periodic benefit cost. The table
assumes all other factors are held constant, including the slope of the discount
rate yield curves.

Goodwill and Certain Long-Lived Assets:





The Company makes certain estimates and judgments in relation to goodwill and
certain long-lived assets. Those include considerations made in the valuation of
certain acquired identifiable definite-lived and indefinite-lived assets as a
result of business combinations as well as considerations in the recoverability
and impairment assessments of long-lived assets and goodwill.



Acquisition of certain identifiable definite-lived and indefinite-lived assets





In conjunction with an acquisition of a business, the Company records
identifiable definite-lived and indefinite-lived intangible assets acquired at
their respective fair values as of the date of acquisition. The corresponding
fair value estimates for these assets acquired include projected future cash
flows, associated discount rates used to calculate present value, asset life
cycles, royalty rates, and customer retention rates. The fair value calculated
for indefinite-lived intangible assets such as certain tradenames, in addition
to intangible assets that are definite-lived such as patents, customer
relationships, tradenames and other technology-based assets may change during
the finalization of the purchase price allocation, due to the significant
estimates used in determining their fair value. As a result, the Company may
make adjustments to the provisional amounts recorded for certain items as part
of the purchase price allocation subsequent to the acquisition, not to exceed
one year after the acquisition date, until the purchase accounting allocation is
finalized.


Assessments of long-lived assets and goodwill





As of December 31, 2020, net property, plant and equipment totaled $9.4 billion
and net identifiable intangible assets totaled $5.8 billion, of which $0.7
billion related to indefinite-lived tradenames. In addition, 3M goodwill totaled
approximately $13.8 billion as of December 31, 2020. Long-lived assets with a
definite life are tested for impairment whenever events or circumstances
indicate that the carrying amount of an asset (asset group) may not be
recoverable. An impairment loss is recognized when the carrying amount exceeds
the estimated undiscounted cash flows from the asset's or asset group's ongoing
use and eventual disposition. If an impairment is identified, the amount of the
impairment loss 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. Intangible assets with an indefinite life, namely certain
tradenames, are not amortized. Indefinite-lived intangible assets are tested for
impairment annually and are tested for impairment between annual tests if an
event occurs or circumstances change that would indicate that the carrying
amount may be impaired. An impairment loss would be recognized when the fair
value is less than the carrying value of the indefinite-lived intangible asset.
Goodwill is tested for impairment annually in the fourth quarter of each year,
as further discussed below, and is tested between annual tests if an event
occurs or circumstances change that would indicate the carrying amount may be
impaired. If future non-cash asset impairment charges are taken, 3M would expect
that only a portion of the long-lived assets or goodwill would be impaired.

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 asset group. Factors which could result in future
impairment charges include, among others, changes in worldwide economic
conditions, changes in competitive conditions and customer preferences, and
fluctuations in foreign currency exchange rates. These risk factors are
discussed in Item 1A, "Risk Factors," of this document. In addition, changes in
the weighted average cost of capital could also impact impairment testing
results.



As of December 31, 2020, the $0.7 billion of indefinite-lived tradenames
primarily relates to Capital Safety (acquired in 2015), whose tradenames ($520
million at acquisition date) have been in existence for over 60 years (refer to
Note 4 for more detail). The primary valuation technique used in estimating the
fair value of indefinite lived intangible assets (tradenames) is a discounted
cash flow approach. Specifically, a relief of royalty rate is applied to
estimated sales, with the resulting amounts then discounted using an appropriate
market/technology discount rate. The relief of royalty rate is the estimated
royalty rate a market participant would pay to acquire the right to
market/produce the product. In the first quarter of 2020, 3M reflected an
immaterial charge related to impairment of certain indefinite-lived assets in
2020. Based on annual impairment testing in the third quarter of 2020, no
additional impairment was indicated.



3M goodwill totaled approximately $13.8 billion as of December 31, 2020. 3M's
annual goodwill impairment testing is performed in the fourth quarter of each
year. Impairment testing for goodwill is done at a reporting unit level, with
all goodwill assigned to a reporting unit. Reporting units are one level below
the business segment level, but are required to be combined when reporting

units

                                       42

  Table of Contents

within the same segment have similar economic characteristics. At 3M, reporting
units correspond to a division. 3M did not combine any of its reporting units
for impairment testing. An impairment loss would be recognized when the carrying
amount of the reporting unit's net assets exceeds the estimated fair value of
the reporting unit, and the loss would equal that difference. 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. 3M typically uses the price/earnings ratio
approach for stable and growing businesses that have a long history and track
record of generating positive operating income and cash flows. 3M uses the
discounted cash flow approach for start-up, loss position and declining
businesses, in addition to using for businesses where the price/earnings ratio
valuation method indicates additional review is warranted. 3M also uses
discounted cash flow as an additional tool for businesses that may be growing at
a slower rate than planned due to economic or other conditions. Where
applicable, 3M uses a weighted-average discounted cash flow analysis for certain
divisions, using projected cash flows that were weighted based on different
sales growth and terminal value assumptions, among other factors. The weighting
was based on management's estimates of the likelihood of each scenario
occurring.



As described in Note 19, effective in the first quarter of 2020, the Company
changed its business segment reporting. For any product changes that resulted in
reporting unit changes, the Company applied the relative fair value method to
determine the impact on goodwill of the associated reporting units, the results
of which were immaterial. In conjunction with the change in segment reporting,
3M completed an assessment indicating no goodwill impairment existed as a result
of this new segment structure. The discussion that follows relates to the
separate fourth quarter 2020 annual impairment test and is in the context of the
reporting unit structure that existed at that time.



Based on the annual test in the fourth quarter of 2020, no goodwill impairment
was indicated for any of the reporting units. As of October 1, 2020, 3M had 22
primary reporting units, with ten reporting units accounting for approximately
93 percent of the goodwill. These ten reporting units were comprised of the
following divisions: Advanced Materials, Display Materials and Systems,
Electronics Materials Solutions, Health Information Systems, Industrial
Adhesives and Tapes, Medical Solutions, Oral Care Solutions, Personal Safety,
Separation and Purification Sciences, and Transportation Safety.



3M is a highly integrated enterprise, where businesses share technology and leverage common fundamental strengths and capabilities, thus many of 3M's businesses could not easily be sold on a stand-alone basis. 3M's focus on research and development has resulted in a portion of 3M's value being comprised of internally developed businesses that have no goodwill associated with them.

3M will continue to monitor its reporting units and asset groups in 2021 for any triggering events or other indicators of impairment.

Uncertainty in Income Tax Positions:





The extent of 3M's operations involves dealing with uncertainties and judgments
in the application of complex tax regulations in a multitude of jurisdictions.
The final taxes paid are dependent upon many factors, including negotiations
with taxing authorities in various jurisdictions and resolution of disputes
arising from federal, state, and international tax audits. The Company
recognizes potential liabilities and records tax liabilities for anticipated tax
audit issues in the United States and other tax jurisdictions based on its
estimate of whether, and the extent to which, additional taxes will be due. The
Company follows guidance provided by ASC 740, Income Taxes, a subset of which
relates to uncertainty in income taxes, to record these liabilities (refer to
Note 10 for additional information). The Company adjusts these reserves in light
of changing facts and circumstances; however, due to the complexity of some of
these uncertainties, the ultimate resolution may result in a payment that is
materially different from the Company's current estimate of the tax liabilities.
If the Company's estimate of tax liabilities proves to be less than the ultimate
assessment, an additional charge to expense would result. If payment of these
amounts ultimately proves to be less than the recorded amounts, the reversal of
the liabilities would result in tax benefits being recognized in the period when
the Company determines the liabilities are no longer necessary.



NEW ACCOUNTING PRONOUNCEMENTS


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

FINANCIAL CONDITION AND LIQUIDITY


The strength and stability of 3M's business model and strong free cash flow
capability, together with proven capital markets access, provides financial
flexibility and enables the Company to invest through business cycles. Investing
in 3M's business to drive organic growth and deliver strong returns on invested
capital remains the first priority for capital deployment. This includes
research and development, capital expenditures, and commercialization
capability. Organic investments will be supplemented by complementary
acquisitions. The Company also continues to actively manage its portfolio to
maximize value for shareholders. Given uncertainty arising from COVID-19, the
Company suspended repurchases under its board-approved share repurchase program
effective March 2020 with other repurchase activity limited to 3M's stock
compensation plans. 3M will continue to return cash to shareholders through
dividends and plans to resume share repurchases in 2021. 3M maintains strong
liquidity and further added to its liquidity position through the issuance of
$1.75 billion in registered notes in March 2020. To fund cash needs in the
United States, the Company relies on ongoing cash flow from U.S. operations,
access to capital markets and repatriation of the earnings of its foreign
affiliates that are not considered to be permanently reinvested. For those
international earnings still considered to be reinvested indefinitely, the
Company currently has no plans or intentions to repatriate these funds for U.S.
operations. See Note 10 for further information on earnings considered to be
reinvested indefinitely.



3M's primary short-term liquidity needs are met through cash on hand and U.S.
commercial paper issuances. 3M believes it will have continuous access to the
commercial paper market. 3M's commercial paper program permits the Company to
have a maximum of $5 billion outstanding with a maximum maturity of 397 days
from date of issuance. At December 31, 2020, there was no commercial paper

issued and outstanding.



Total Debt:



The strength of 3M's credit profile and significant ongoing cash flows provide
3M proven access to capital markets. Additionally, the Company's debt maturity
profile is staggered to help ensure refinancing needs in any given year are
reasonable in proportion to the total portfolio. 3M currently has an A1 credit
rating with a negative outlook from Moody's Investors Service and an A+ credit
rating with negative outlook from Standard and Poor's.



The Company's total debt was $1.5 billion lower at December 31, 2020 when
compared to December 31, 2019. Decreases in debt are further described in Note
12 and include the repayment of aggregate $445 million principal amount of Third
Lien Notes subject to in-substance defeasance, 650 million euros and $500
million aggregate principal amount of floating-rate medium-term notes that
matured, the December 2020 repayment of $1 billion aggregate principal amount of
notes related to make-whole-call offers, lower commercial paper balance, and the
repayment of the 80 billion Japanese yen and 150 million euro credit facilities.
These decreases were partially offset by the March 2020 issuance of $1.75
billion of registered notes. For discussion of repayments of and proceeds from
debt refer to the following "Cash Flows from Financing Activities" section.



In July 2017, the United Kingdom's Financial Conduct Authority announced that it
would no longer require banks to submit rates for the London InterBank Offered
Rate ("LIBOR") after 2021. In November 2020, the ICE Benchmark Administration
(IBA), LIBOR's administrator, proposed extending the publication of USD LIBOR
through June 2023. The Company has reviewed its debt securities, bank
facilities, and derivative instruments and continues to evaluate commercial
contracts that may utilize LIBOR as the reference rate. 3M will continue its
assessment and monitor regulatory developments during the transition period.



Effective February 10, 2020, the Company updated its "well-known seasoned
issuer" (WKSI) shelf registration statement, which registers an indeterminate
amount of debt or equity securities for future issuance and sale. This replaced
3M's previous shelf registration dated February 24, 2017. In May 2016, in
connection with the WKSI shelf, 3M entered into an amended and restated
distribution agreement relating to the future issuance and sale (from time to
time) of the Company's medium-term notes program (Series F), up to the aggregate
principal amount of $18 billion, which was an increase from the previous
aggregate principal amount up to $9 billion of the same Series.



As of December 31, 2020, the total amount of debt issued as part of the
medium-term notes program (Series F), inclusive of debt issued in February 2019
and prior years is approximately $17.6 billion (utilizing the foreign exchange
rates applicable at the time of issuance for the euro denominated debt).
Additionally, the August 2019 and March 2020 debt was issued under the WKSI
shelf registration, but not as part of the medium-term notes program (Series F).
Information with respect to long-term debt issuances and maturities for the
periods presented is included in Note 12.

The Company has a $3.0 billion five-year revolving credit facility expiring in
November 2024. The revolving credit agreement includes a provision under which
3M may request an increase of up to $1.0 billion (at lender's discretion),
bringing the total facility up to $4.0 billion. In addition, 3M entered into a
$1.25 billion 364-day credit facility, which was renewed in November 2020 with
an expiration date of November 2021. The 364-day credit agreement includes a
provision under which 3M may convert any advances outstanding on the maturity
date into term loans with a maturity date one year later. These credit
facilities were undrawn at December 31, 2020. Under both the $3.0 billion and
$1.25 billion credit agreements, the Company is required to maintain its EBITDA
to Interest Ratio as of the end of each fiscal quarter at not less than 3.0 to
1. This is calculated (as defined in the agreement) as the ratio of consolidated
total EBITDA for the four consecutive quarters then ended to total interest
expense on all funded debt for the same period. At December 31, 2020, this ratio
was approximately 17 to 1. Debt covenants do not restrict the payment of
dividends.



Apart from the committed credit facilities described above, in September 2019,
3M entered into a credit facility initially expiring in July 2020 that was
further extended to August 2021 in the amount of 80 billion Japanese yen. In
November 2019, 3M entered into a credit facility expiring in November 2020 in
the amount of 150 million euros. During the third quarter of 2020, the Company
paid the outstanding balances and closed these credit facilities. The Company
also had $273 million in stand-alone letters of credit and bank guarantees
issued and outstanding at December 31, 2020. These instruments are utilized in
connection with normal business activities.



Cash, Cash Equivalents and Marketable Securities:





At December 31, 2020, 3M had $5.1 billion of cash, cash equivalents and
marketable securities, of which approximately $2.8 billion was held by the
Company's foreign subsidiaries and approximately $2.3 billion was held by the
United States. These balances are invested in bank instruments and other
high-quality fixed income securities. At December 31, 2019, 3M had $2.5 billion
of cash, cash equivalents and marketable securities, of which approximately $2.4
billion was held by the Company's foreign subsidiaries and approximately $100
million was held by the United States. The increase from December 31, 2019
primarily resulted from strong cash flow from operations, reduced capital
expenditures, and lower share repurchases.



Net Debt (non-GAAP measure):


Net debt is not defined under U.S. GAAP and may not be computed the same as
similarly titled measures used by other companies. The Company defines net debt
as total debt less the total of cash, cash equivalents and current and long-term
marketable securities. 3M believes net debt is meaningful to investors as 3M
considers net debt and its components to be important indicators of liquidity
and financial position. The following table provides net debt as of December 31,
2020 and 2019.

Balance Sheet:



3M's strong balance sheet and liquidity provide the Company with significant
flexibility to fund its numerous opportunities going forward. The Company will
continue to invest in its operations to drive growth, including continual review
of acquisition opportunities.


The Company uses working capital measures that place emphasis and focus on certain working capital assets, such as accounts receivable and inventory activity.

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 is not defined under U.S. generally accepted accounting
principles and may not be computed the same as similarly titled measures used by
other companies. The Company defines working capital as current assets minus
current liabilities. 3M believes working capital is meaningful to investors as a
measure of operational efficiency and short-term financial health.



Working capital increased $3.3 billion compared with December 31, 2019. Balance
changes in current assets increased working capital by $2.0 billion, driven by
increases in cash and cash equivalents and inventory, partially offset by
decreases in accounts receivable. Balance changes in current liabilities
increased working capital by $1.3 billion, primarily due to decreases in
short-term borrowing and the current portion of long-term debt.



Accounts receivable decreased $86 million from December 31, 2019, primarily due
to ongoing collection management and increased expected credit losses on
customer receivables related to COVID-19 uncertainty. Inventory increased $105
million from December 31, 2019 primarily as a result of foreign currency
impacts. These increases were partially offset by inventory decreases as a
result of the divestiture of the drug delivery business.



Return on Invested Capital (non-GAAP measure):





Return on Invested Capital (ROIC) is not defined under U.S. generally accepted
accounting principles. Therefore, ROIC should not be considered a substitute for
other measures prepared in accordance with U.S. GAAP and may not be comparable
to similarly titled measures used by other companies. The Company defines ROIC
as adjusted net income (net income including non-controlling interest plus
after-tax interest expense) divided by average invested capital (equity plus
debt). The Company believes ROIC is meaningful to investors as it focuses on
shareholder value creation. The calculation is provided in the below table.

  Table of Contents

In 2020, ROIC of 18.2 percent was higher than 2019. The increase was driven by
the lower year-over-year impact of significant litigation-related charges in
addition to the non-repeating charge from the 2019 deconsolidation of the
Company's Venezuela subsidiary. 2019 ROIC was also negatively impacted by the
increase in cash and cash equivalents in anticipation of the funding of the

acquisition of Acelity.

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 2020, cash flows provided by operating activities increased $1.0 billion
compared to the same period last year, with this increase primarily due to cost
saving actions taken in response to COVID-19 and lower year-on-year significant
litigation-related charges and the timing of associated payments. The
combination of accounts receivable, inventories and accounts payable improved
operating cash flow by $326 million in 2020, compared to an operating cash flow
improvement of $598 million in 2019. Additional discussion on working capital
changes is provided earlier in the "Financial Condition and Liquidity" section.

Investments in property, plant and equipment enable growth across many diverse
markets, helping to meet product demand and increasing manufacturing efficiency.
In 2020, 3M reduced overall spending in light of uncertainty regarding COVID-19,
but continued to invest in expanding the Company's ability to increase
production of respiratory products to meet worldwide demand. The Company expects
2021 capital spending to be approximately $1.8 billion to $2.0 billion as 3M
continues to invest in growth, productivity and sustainability.



3M records capital-related government grants earned as reductions to the cost of property, plant and equipment; and associated unpaid liabilities and grant proceeds receivable are considered non-cash changes in such balances for purposes of preparation of statement of cash flows.





3M invests in renewal and maintenance programs, which pertain to cost reduction,
cycle time, maintaining and renewing current capacity, eliminating pollution,
and compliance. Costs related to maintenance, ordinary repairs, and certain
other items are expensed. 3M also invests in growth, which adds to capacity,
driven by new products, both through expansion of current facilities and new
facilities. Finally, 3M also invests in other initiatives, such as information
technology (IT), laboratory facilities, and a continued focus on investments in
sustainability.

2020 Debt Activity:



Total debt was approximately $18.8 billion at December 31, 2020 and $20.3
billion at December 31, 2019. Repayment of debt primarily consists of the
aggregate $445 million principal amount of Third Lien Notes and the 650 million
euros and $500 million aggregate principal amount of floating-rate medium-term
notes that matured in May 2020 and August 2020, respectively. During the third
quarter of 2020, the Company paid the outstanding balances on their Japanese yen
and euro credit facilities. In addition, $1.0 billion aggregate principal amount
of notes maturing in September 2021 were repaid in December 2020 via
make-whole-call offers. Increases in debt were related to the March 2020
issuance of $1.75 billion in registered notes. There was no outstanding
commercial paper at December 31, 2020, as compared to $150 million at
December 31, 2019. Net commercial paper issuances in addition to repayments and
borrowings by international subsidiaries are largely reflected in "Change in
short-term debt - net" in the preceding table. 3M's primary short-term liquidity
needs are met through cash on hand and U.S. commercial paper issuances. Refer to
Note 12 for more detail regarding debt.



2019 Debt Activity:



Total debt was approximately $5.7 billion higher at December 31, 2019 when
compared to December 31, 2018. Increases in debt related to the first quarter
and third quarter 2019 issuances of $2.25 billion of medium-term notes and $3.25
billion of other registered notes, respectively, 69 billion Japanese yen
(approximately $632 million at December 31, 2019 exchange rates) outstanding
from the 80 billion Japanese yen credit facility established in September 2019,
150 million euros (approximately $168 million at December 31, 2019 exchange
rates) outstanding credit facility established in November 2019, and $0.5
billion of debt assumed and not yet repaid as a result of the Company's
acquisition of Acelity Inc. Repayment of debt primarily consists of the June
2019 repayment of $625 million aggregate principal amount of fixed-rate
medium-term notes that had matured, in addition to debt assumed and subsequently
repaid as a result of the Company's acquisitions of M*Modal and Acelity Inc. as
discussed in Note 3. Outstanding commercial paper decreased $285 million from
December 31, 2018 to December 31, 2019. Refer to Note 12 for more detail
regarding debt.

Repurchases of Common Stock:





Repurchases of common stock are made to support the Company's stock-based
employee compensation plans and for other corporate purposes. In November 2018,
3M's Board of Directors replaced the Company's February 2016 repurchase program
with a new repurchase program. This new program authorizes the repurchase of up
to $10 billion of 3M's outstanding common stock, with no pre-established end
date. In 2020, the Company purchased $0.4 billion of its own stock, compared to
purchases of $1.4 billion in 2019. As of December 31, 2020, approximately $7.8
billion remained available under the authorization. In the first quarter of
2020, the Company suspended repurchases under its board-approved share
repurchase program with other repurchase activity limited to 3M's stock
compensation plans. The Company plans to resume share purchases in 2021. For
more information, refer to the table titled "Issuer Purchases of Equity
Securities" in Part II, Item 5. The Company does not utilize derivative
instruments linked to the Company's stock.



Dividends Paid to Shareholders:





Cash dividends paid to shareholders totaled $3.388 billion ($5.88 per share) in
2020, $3.316 billion ($5.76 per share) in 2019, and $3.193 billion ($5.44 per
share) in 2018. 3M has paid dividends since 1916. In February 2021, 3M's Board
of Directors declared a first-quarter 2021 dividend of $1.48 per share, an
increase of 1 percent. This is equivalent to an annual dividend of $5.92 per
share and marked the 63rd consecutive year of dividend increases.



Other cash flows from financing activities may include various other items, such
as cash paid associated with certain derivative instruments, distributions to or
sales of noncontrolling interests, changes in cash overdraft balances, and
principal payments for finance leases.



Free Cash Flow (non-GAAP measure):





Free cash flow and free cash flow conversion are not defined under U.S.
generally accepted accounting principles (GAAP). Therefore, they should not be
considered a substitute for income or cash flow data prepared in accordance with
U.S. GAAP and may not be comparable to similarly titled measures used by other
companies. The Company defines free cash flow as net cash provided by operating
activities less purchases of property, plant and equipment. It should not be
inferred that the entire free cash flow amount is available for discretionary
expenditures. The Company defines free cash flow conversion as free cash flow
divided by net income attributable to 3M. The Company believes free cash flow
and free cash flow conversion are meaningful to investors as they are useful
measures of performance and the Company uses these measures as an indication of
the strength of the company and its ability to generate cash. The first quarter
of each year is typically 3M's seasonal low for free cash flow and free cash
flow conversion. Below find a recap of free cash flow and free cash flow
conversion.



Refer to the preceding "Cash Flows from Operating Activities" and "Cash Flows
from Investing Activities" sections for discussion of items that impacted the
operating cash flow and purchases of PP&E components of the calculation of free
cash flow. Refer to the preceding "Results of Operations" section for discussion
of items that impacted the net income attributable to 3M component of the
calculation of free cash flow conversion.

Off-Balance Sheet Arrangements and Contractual Obligations:





As of December 31, 2020, the Company has not utilized special purpose entities
to facilitate off-balance sheet financing arrangements. Refer to the section
entitled "Warranties/Guarantees" in Note 16 for discussion of accrued product
warranty liabilities and guarantees.



In addition to guarantees, 3M, in the normal course of business, periodically
enters into agreements that require the Company to indemnify either major
customers or suppliers for specific risks, such as claims for injury or property
damage arising out of the use 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 results of operations or
financial condition.

As a result of put provisions associated with certain debt instruments, long-term debt payments due in 2021 include floating rate notes totaling $53 million (classified as current portion of long-term debt).


In conjunction with the 2017 Tax Cuts and Jobs Act (TCJA), the Company has a
transition tax liability that is payable over 8 years beginning in 2018. See
Note 10 for additional details.



Unconditional purchase obligations are defined as agreements to purchase goods
or services that are 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

                                       51

  Table of Contents

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. Contractual capital commitments are included in the preceding
table, but these commitments represent a small part of the Company's expected
capital spending. 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 amounts will not provide a reliable indicator of the Company's expected
future cash outflows on a stand-alone basis.



Other obligations, included in the preceding table within the caption entitled
"Unconditional purchase obligations and other" include the current portion of
the liability for uncertain tax positions under ASC 740, which is expected to be
paid out in cash in the next 12 months, when applicable. The Company is not able
to reasonably estimate the timing of the long-term payments, or the amount by
which the liability will increase or decrease over time; therefore, the
long-term portion of the total net tax liability of $933 million is excluded
from the preceding table. In addition, the transition tax prescribed under the
Tax Cuts and Jobs Act (TCJA) is separately included in the table above. Refer to
Note 10 for further details. Additionally, included within the caption entitled
"Unconditional purchase obligations and other" are operating lease commitments
that have not yet commenced, which as of December 31, 2020, totaled
approximately $18 million. These commitments pertain to 3M's right of use
buildings.



As discussed in Note 13, the Company does not have a required minimum cash
pension contribution obligation for its U.S. plans in 2021 and Company
contributions to its U.S. and international pension plans are expected to be
largely discretionary in future years; therefore, amounts related to these plans
are not included in the preceding table.



FINANCIAL INSTRUMENTS



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 to offset, in part, the impacts of changes in value of
various non-functional currency denominated items including certain intercompany
financing balances. 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 and price protection agreements.



Refer to Item 7A, "Quantitative and Qualitative Disclosures About Market Risk", for further discussion of foreign exchange rates risk, interest rates risk, commodity prices risk and value at risk analysis.
