Item 1.  Description of Business

American Power Conversion Corporation
American Power Conversion Corporation, APC, designs, develops, manufactures, and
markets  power protection and management solutions for computer, communications,
and electronic applications worldwide.  Our solutions include:
    Uninterruptible power supply products, commonly known as UPSs;
    DC-power solutions;
    Electrical surge protection devices, also known as surge suppressors;
    Power conditioning products;
    Precision cooling equipment; and
    Associated software, services, and accessories.

These  solutions  are  used  with sensitive electronic  devices  which  rely  on
electric  utility  power including, but not limited to, home  electronics,  PCs,
high-performance   computer   workstations,   servers,   networking   equipment,
communications  equipment, Internetworking equipment,  data  centers,  mainframe
computers, and facilities.

Our  UPS  products regulate the flow of utility power to ensure safe  and  clean
power to the protected equipment and provide seamless back-up power in the event
of  the  loss  of utility power.  The back-up power lasts for a period  of  time
sufficient  to  enable  the  user to continue computer  operations,  conduct  an
orderly  shutdown of the protected equipment, preserve data, work through  short
power outages or, in some cases, continue operating for several hours or longer.

Our DC-power solutions are highly configurable designs that continuously monitor
and  isolate  end-user  equipment from utility voltage  fluctuations,  frequency
variations,  and  electrical noise.  In the event of a  power  failure,  the  DC
products  seamlessly provide back-up power for critical communications networks,
allowing users emergency access to these networks for a period of many hours.

Our  surge protection devices and power conditioning products provide protection
from  electrical  power surges and noise in the flow of  utility  power.   APC's
precision  cooling equipment regulates temperature and humidity.   Our  software
and  accessory solutions enhance monitoring, management, and performance of  our
UPS  products,  and our service offerings assist the end-user with installation,
configuration, and maintenance of our products.

Segments
APC  operates  primarily  within  one industry consisting  of  three  reportable
operating  segments  by  which we manage our business  and  from  which  various
offerings  are  commonly combined to develop a total solution for the  customer.
These  efforts primarily incorporate the design, manufacture, and  marketing  of
power  protection equipment and related software and accessories  for  computer,
communications, and related equipment.  Our three segments are:  Small  Systems,
Large Systems and Other.  Each of these segments address global markets.

The  Small  Systems segment develops power solutions for servers and  networking
equipment  commonly used in local area and wide area networks and  for  personal
computers and sensitive electronics.  Major product offerings include the Smart-
UPSr,  Matrix-UPSr, Symmetrar Power Arrayr and Back-UPSr family of  UPSs.   Also
included  are  the  SurgeArrestr  surge  suppressors  as  well  as  cabling  and
connectivity  solutions.   Additional  accessories  and  software  products  are
offered   to  enhance  the  management  of  these  networks.   Products  include
PowerChuter  software, MasterSwitchT power distribution units,  and  NetShelterr
server  enclosures.   Products are sold to home and commercial  users  primarily
through  an  indirect  selling  model consisting of  computer  distributors  and
dealers,  value  added resellers, mass merchandisers, catalog merchandisers,  E-
commerce vendors, and strategic partnerships.

                                        2

The Large Systems segment produces large system solutions that provide power and
availability   solutions  for  data  centers,  facilities,  and   communications
equipment.   Product  offerings  include  Silconr  UPSs,  NetworkAIRT  precision
cooling  equipment,  and DC-power solutions.  Products are  sold  to  commercial
users  primarily  through an indirect selling model consisting  of  value  added
resellers and strategic partnerships.

The  Other  segment  provides  Web-based  informational,  product,  and  selling
services  as  well as replacement batteries for the Company's UPS  products  and
notebook computers.

Information on reportable operating segment net sales, profit from operations,
and depreciation for each of the last three years is located in note 10 of Notes
to Consolidated Financial Statements in Item 8 of this Report.

APC  was  incorporated under the laws of the Commonwealth  of  Massachusetts  on
March  11,  1981.  Executive offices are located at 132 Fairgrounds  Road,  West
Kingston, RI 02892, our telephone number is (401) 789-5735 and our Web  site  is
www.apc.com.

Market Overview
The  growth  of  the  power protection industry has been  fueled  by  the  rapid
proliferation  of  microprocessor-based equipment and  related  systems  in  the
corporate marketplace and in the small office/home office environment.  PCs  and
servers  have become an integral part of the overall business strategy  of  many
organizations  as  well  as  in  many technical, scientific,  and  manufacturing
settings.  Businesses continue to store, manipulate, and transfer data via local
area and wide area networks as well as via corporate intranets and the Internet.
Additionally,  there has been a rise in the installation of large  data  centers
and Web hosting facilities to support the rapidly growing Internet-based market.
APC's  products  protect  both the hardware and data stored  in,  and  traveling
through,  these  networks from power disturbances.  The  products  also  provide
battery  back-up  to enhance productivity through the continued availability  of
networks, sensitive electronics, and even facilities during power outages.

We  believe  that  the  increased awareness of the costs and  lost  productivity
associated  with  poor power quality has increased demand for  power  protection
products.   Complete failures, surges, or sags in the electrical power  supplied
by  a  utility  can  cause  computers  and electronic  systems  to  malfunction,
resulting  in costly downtime, damaged or lost data files, and damaged hardware.
A  UPS  protects against these power disturbances by providing continuous  power
automatically and virtually instantaneously after the electric power  supply  is
interrupted.  UPSs also provide line filtering and protection against surges  or
sags  while the electric utility is operating.  In international regions,  power
quality  often  results in varied levels of distortions and, as a result,  these
areas provide us with additional opportunities for our products.

In  2000,  we  focused  on  providing global,  end-to-end,  Nonstop  NetworkingT
solutions  for  the  PC,  server,  data center, communications,  and  enterprise
systems  marketplace.  Particular emphasis was placed on our Large  Systems  and
the  rapidly  growing market for large UPS systems with Fortune 1000  companies,
Internet  service providers, Web hosting, and co-locators who use large  amounts
of  information technology, or IT, equipment to support their businesses.  APC's
operations   worldwide   were  impacted  by  the  growth   of   networking-based
applications, the continued rapid expansion of Internet-based applications,  the
growth of the PC market, and the continued poor and unreliable quality of  power
worldwide.

Our  goals are to 1) target the sales of UPSs with new IT equipment; 2) have the
products and presence to succeed in new geographies; and 3) continue to position
APC as the UPS and power availability provider of choice.  We continue to target
promotional  efforts at both consumer and commercial markets, which  we  believe
represent   growth  opportunities, and continue to target  industries  that  are
dependent  on  electronic  systems,  such as  the  communications  industry,  as
potential market growth opportunities.

Products
APC's  strategy  is  to design and manufacture products that  incorporate  high-
performance and quality at competitive prices.  Our products are designed to fit
seamlessly  into  the  computer, networking, and communications  environments of
businesses,   homes,  and  small  offices/home  offices.   These  products   are
engineered  and  extensively tested for compatibility with  leading  information
technology hardware and software.

Service Programs

Warranties
APC  provides service programs to our customers for in-warranty UPS products and
out-of-warranty UPS products, as well as for product installation and  start-up.
There  are  two-year and one-year limited warranties covering UPS, DC-power  and
NetworkAir products.  Customers can extend the basic warranty period  of  select
products,  at  an  additional charge, for a period of one  or  three  additional
years.   In-warranty service programs allow customers to return  their  original
unit  for repair and, if found defective, we will replace the original unit with
a  factory  reconditioned unit or, if requested, repair the  original  unit  and
return  it  to  the  customer.  The extended warranty can be  purchased  anytime
during the standard warranty period. For a fixed fee, which varies by model,  we
will replace an out-of-warranty UPS unit with a factory reconditioned unit.   We
also  offer  a  standard one-year limited warranty which covers  certain  Silcon
product parts.  This warranty can be extended in annual increments for a  period
not  to exceed ten years.  Additionally, customers can purchase on-site service,
preventative maintenance, and power availability consulting.  On-site service is
offered through APC's service department and third party vendors.  We also offer
Trade-UPS programs for customers to upgrade old APC or competitive units to  new
APC units.

                                        4

Equipment Protection Policy
APC  offers  an  Equipment  Protection Policy in the  US, Canada, and  European
Community.   Depending  on  the model and country, the  policy  provides  up  to
$25,000,  50,000 pounds sterling, or 100,000 euros for repair or replacement  of
customers'  hardware should a surge or lightning strike pass through  a  Company
unit.   Other  restrictions  also  apply.   Customers  can  also  register   the
ProtectNetr  line of data line surge suppressors for a "Double-Up"  Supplemental
Equipment  Protection Policy, under which the total recoverable limit under  the
Equipment  Protection  Policy is doubled (U.S. and Canada only).  Most surge
suppressor  products  come with a lifetime product warranty.

Our products have experienced satisfactory field operating results, and warranty
costs  incurred  to  date  have not had a significant  impact  the  consolidated
results of operations.

Distribution Channels
APC  markets  its products to businesses, small offices/home offices,  and  home
users  around  the  world  through a variety of  distribution  channels.   These
channels include:
    Computer distributors and dealers;
    Value added resellers;
    Mass merchandisers;
    Catalog merchandisers;
    E-commerce vendors; and
    Strategic partnerships.

We  also  sell  directly  to some large value added resellers,  which  typically
integrate our products into specialized computer systems and then market turnkey
systems to selected vertical markets.  Additionally, certain select products are
sold  directly to manufacturers for incorporation into products manufactured  or
packaged by them.

Two  customers,  Ingram  Micro and Tech Data Product Management,  accounted  for
approximately  15%  and  11%, respectively, of net  sales  in  2000.  No  single
customer comprised 10% or more of APC's net sales in 1999.  One customer, Ingram
Micro,  accounted for approximately 11% of our net sales in 1998.  The  majority
of  our  sales to Ingram Micro and Tech Data Product Management are included  in
the Small Systems segment.

Sales and Marketing
APC's  sales  and  marketing organizations are primarily  responsible  for  four
activities:   sales,  marketing, customer service, and technical  support.   Our
sales  force  is  responsible  for  relationships  with  distributors,  dealers,
strategic  partners,  and  end-users  as well  as  developing  new  distribution
channels, particularly in geographic and product application areas into which we
are  expanding.   We  have  charged  our sales force  with  providing  customers
comprehensive product and service solutions to meet their power availability and
management needs.

Our marketing activities include market research, product planning, trade shows,
sales  and pricing strategies, and product sales literature.  We utilize  direct
marketing  efforts domestically and internationally, including  direct  mailings
and  print,  online/Internet,  radio, and television  advertising,  as  well  as
exhibiting  at  computer trade shows.  Customer service is responsible  for  all
technical marketing inquiries and customer support.  APC has developed a  number
of programs and techniques to support the distribution channels.  These include,
but are not limited to, toll-free phone assistance, online product and technical
information, formal product demonstrations, and reseller trainings.

Supply Chain Management - Manufacturing, Quality, Raw Materials, and
Distribution

Manufacturing
APC's  manufacturing  operations are located in the United States,  Philippines,
Ireland,  China, India, Denmark, Switzerland, and England.  We believe that  our
long-term  success depends on, among other things, the ability  to  control  our
costs.    We  utilize  lean  "cell"  based  manufacturing  processes,  automated
manufacturing  techniques, and extensive quality control in  order  to  minimize
costs and maximize product reliability.  In addition, the design of products and
the  commonality of parts allow for efficient circuit board component insertion,
wave  soldering,  and  in-process  testing.   Quality  control  procedures   are
performed at the component, sub-assembly, and finished product levels.   We  are
committed  to  an  ongoing  effort to enhance the overall  productivity  of  our
manufacturing facilities.

Quality
APC  has been ISO 14001 and ISO 9001 certified by the International Organization
for  Standardization.  Our systems have been audited to the stringent ISO  14001
and  ISO  9001 levels at our manufacturing facilities in Rhode Island,  Ireland,
Denmark, China, India, and the Philippines.  The International Organization  for
Standardization has also certified our manufacturing efforts in England and  our
Massachusetts Research and Development Center to the ISO 9001 level.

Raw Materials
We  generally  purchase devices and components from more than one  source  where
alternative sources are available; however, we do use sole source suppliers  for
certain  components.   We  believe that alternative components  for  these  sole
source  items could be incorporated into our products, if necessary.   While  we
have  been  able  to  obtain adequate supplies of components  from  sole  source
suppliers,  the  future unavailability of components from these suppliers  could
disrupt  production  and  delivery of products until an  alternative  source  is
identified.

Distribution
APC  continues to invest in a worldwide distribution network that  delivers  our
products and services to our customers.  We own or lease distribution centers in
numerous countries across the globe.  All distribution centers are connected  to
our  customer service operations via APC's Enterprise Resource Planning  system,
which enables orders received from any point in the network to be fulfilled from
any  distribution  center  throughout the world.  APC employs  several  enhanced
fulfillment  capabilities  in  support of our  overall  E-commerce  initiatives,
including  the use of Electronic Data Interchange transactions between  APC  and
our   distributors  for  receipt  of  orders,  acknowledgement  of  orders,  and
confirmation of shipments.  Additionally, we utilize a suite of Web  tools  that
allows  consumers  and  resellers to view product information,  gain  access  to
pricing information, and place their orders via the Web.

Product Development
APC's  research  and development, or R&D, staff includes engineers  and  support
persons  who  develop new products and provide engineering support for  existing
products.  Our R&D efforts are also aimed at reducing cost and total cycle  time
and  improving  product  and component quality.  Most  of  these  employees  are
located  in  two Massachusetts facilities with additional resources  located  in
Denmark  and  England.  Employees devoted to the improvement and development  of
software products are located in the West Kingston, Rhode Island facility and in
St.  Louis, Missouri, at APC's subsidiary, Systems Enhancement Corporation.   We
believe that the technical expertise of our R&D staff is very important  to  our
growth as technological change is rapid in our markets.

Through  acquisitions in 2000, APC added DC-power solutions  for  communications
applications,  cabling,  and connectivity products for  desktop  and  networking
environments, and precision cooling equipment for data center and communications
gear.   (For  more  information about these acquisitions,  see  the  Acquisition
section  included in Management's Discussion and Analysis of Financial Condition
and  Results  of  Operations  in  Item 7 of this  Report.)   New  UPS  solutions
introduced  during  the year from existing product lines included  new  Back-UPS
Officer models, new Smart-UPS models, new Symmetra Rack-mount Power Arrays,  and
new high end Silcon models in North America.  We introduced solutions for mobile
PC  users, including TravelPowerT laptop power adapters and notebook replacement
battery  cartridges.  Additional power management, monitoring and services  were
also introduced during the year.

                                        6

During  1999,  APC  increased its offerings of products  and  services  for  the
enterprise  market, specifically, geographically expanding the  availability  of
the  Silcon UPS products, introducing new Symmetra models, and introducing APC's
Global Services organization, which offers a comprehensive suite of professional
and   maintenance  services.   Hardware  introductions  primarily   focused   on
enhancements  to the SurgeArrest, Smart-UPS, and Back-UPS lines.   New  software
solutions announced during the year included new versions of the PowerChute plus
software  to expand support of leading operating systems, including support  for
Microsoft  Windows  2000  Beta 3 and expanded support  for  Linux,  as  well  as
integration with leading management platforms.

During  1998, APC expanded its product offerings in the enterprise  market  with
the acquisition of Silcon, a leading manufacturer of 3-phase UPSs up to 500 kVA.
Implementation of APC's enterprise power protection strategy began in 1997  with
the  introduction  of  the Symmetra Power Array, the first scalable  and  fault-
tolerant  power  protection system for multiple servers,  computer  rooms,  call
centers,  and back-office applications.  We also innovated our desktop  line  of
UPSs during 1998, revamping the Back-UPS line and adding new features, including
Universal  Serial  Bus support, to select products in the  Back-UPS  Pror  line.
Additional  areas  of development included new products for the  Internetworking
market,  additional network management support via new PowerChute and  PowerNetr
solutions, and customized hardware and software products for strategic partners.

R&D expenditures were $46.9 million or 3.2% of net sales in 2000, $34.6 million
or 2.6% of net sales in 1999, and $32.6 million or 2.9% of net sales in 1998.

Intellectual Property
We  protect  certain  proprietary rights in our  products  as  well  as  certain
proprietary  technology developments by seeking patent protection.   We  believe
that  the  loss of such rights concerning these developments would  not  have  a
material  adverse effect on our business.  We also license from  others  certain
worldwide  patent rights relating to UPS technology.  With respect to protection
of  those  areas  of  our technology for which patent protection  has  not  been
sought,  we  rely  on the complexity of our technology, trade secrecy  law,  and
employee confidentiality agreements.

APC  has numerous trademarks registered in the United States and in many foreign
countries.   We  also  have  trademark  applications  pending  domestically  and
internationally.   The  trademark "APC" is of principal importance  to  us.   In
addition, a number of other trademarks owned by us have significant importance.

Competition
We  believe that we are one of less than ten global companies providing  a  full
range of UPS products and services worldwide.  Our principal competitors include
Invensys Secure Power, a unit of Invensys plc, consisting of PowerWare (formerly
Exide  Electronics) and Best Power; Liebert Corporation, a division  of  Emerson
Network Power and Emerson Electric Co.; MGE UPS Systems, a privately-held French
company;  Chloride  Power, a subsidiary of Chloride Group  PLC;  and  Phoenixtec
Power  Company Ltd., a publicly-held Taiwanese company.  We also compete with  a
number  of other U.S. and non-U.S. based companies which offer power protection,
DC-power,  and  other products similar to ours.  Some competitors  have  greater
financial and other resources than APC.  We compete in the sale of our  products
on  the  basis  of several factors, including product performance  and  quality,
marketing,  access to distribution channels, customer service,  product  design,
and price.

International Operations
APC has experienced rapid growth internationally and plans to continue to expand
its  international  efforts.   With a full line  of  internationally  positioned
products already available, we continue to staff personnel to serve geographical
markets of interest.  Our manufacturing operations outside of the United  States
are located in the Philippines, Ireland, China, India, Denmark, Switzerland, and
England.   A  significant  portion of products in our Small  Systems  and  Large
Systems reportable operating segments are built internationally, particularly in
the  Philippines.   We believe that the production of these  products  could  be
redeployed to other regions if necessitated.

Our primary sales offices outside of the United States are located in Europe and
the  Far  East.   These  offices,  together  with  offices  in  other  locations
worldwide,  provide  sales  and technical support to our  customers  across  the
globe.   APC  also  owns  or leases distribution centers in  numerous  countries
worldwide, and utilizes third party warehouses in Europe, the Far East,  Canada,
South Africa, and Uruguay for distribution into our international markets.

that  none  will be declared in the foreseeable future. We currently  intend  to
retain any earnings to finance the growth and development of our business.   Any
future  dividends will be at the discretion of the Board of Directors  and  will
depend  upon, among other things, the financial condition, capital requirements,
earnings, and liquidity of APC.


Item 6.  Selected Financial Data

All  amounts  are  in  dollars except for outstanding shares.   Dollars  are  in
thousands  except  for  basic and diluted earnings per  share.   Shares  are  in
thousands.   APC  did not declare any cash dividends for the  five  year  period
presented.  Earnings per share and share data reflect a stock split effected  in
1999.

The  results  of operations of companies acquired in 2000 and 1998 are  included
from  their  respective dates of acquisition.  For more information about  these
acquisitions,  see  the Acquisition section included in Management's  Discussion

Report.

In  consideration  of  guidance  issued by the  Financial  Accounting  Standards
Board's  Emerging Issues Task Force in Issue No. 00-10, "Accounting for Shipping
and  Handling  Fees and Costs," we have retroactively changed our classification
of  freight  charges  billed  to  customers and related  freight  expenses  from
operating  expenses  to net sales and cost of goods sold,  respectively.   These
changes  increased net sales by $10.0 million, $7.7 million, $5.2 million,  $2.9
million,  and  $2.2  million in 2000, 1999, 1998, 1997 and  1996,  respectively;
increased  cost  of goods sold by $30.8 million, $24.7 million,  $24.3  million,
$15.4 million, and $9.6 million in 2000, 1999, 1998, 1997 and 1996 respectively;
and  decreased marketing, selling, general, and administrative expenses by $20.8
million, $17.0 million, $19.1 million, $12.5 million, and $7.4 million in  2000,
1999, 1998, 1997 and 1996, respectively.

Change in Accounting Principle
In  consideration  of  guidance  issued by the  Financial  Accounting  Standards
Board's  Emerging Issues Task Force in Issue No. 00-10, "Accounting for Shipping
and  Handling  Fees and Costs," we have retroactively changed our classification
of  freight  charges  billed  to  customers and related  freight  expenses  from
operating  expenses  to net sales and cost of goods sold,  respectively.   These
changes increased net sales by $10.0 million, $7.7 million, and $5.2 million  in
2000,  1999  and  1998,  respectively; increased cost of  goods  sold  by  $30.8
million,  $24.7 million, and $24.3 million in 2000, 1999 and 1998, respectively;
and  decreased marketing, selling, general, and administrative expenses by $20.8
million,  $17.0 million, and $19.1 million in 2000, 1999 and 1998, respectively.
This  accounting  change had no impact on reported net income  for  any  of  the
periods presented.

Revenues
Net  sales  in  fiscal  year 2000 increased by 10.3% to  $1,483.6  million  from
$1,344.9  million in fiscal year 1999, which had increased 18.9%, from  $1,131.0
million  in  fiscal year 1998.  The increases from 1998 to 2000  included  sales
attributable  to  2000  and  1998 acquisitions  (see  Acquisitions  below).   In
addition, sales of new products and increased efforts by APC's sales force  have
contributed  to increased sales volumes; net sales attributable to new  products
totaled  approximately 12%, 7%, and 11%, of 2000, 1999 and  1998,  respectively.
Sales   for  products  in  the  Small  Systems  segment  addressing  networking
applications  and desktop PCs were negatively impacted by industry  softness  in
the  IT  markets, weakening global economies, and maturing markets.   The  Large
Systems  segment  experienced healthy growth driven by  the  build-out  of  data
centers and share gains in the 3-phase UPS market as well as the acquisition  of
DC-Power  and  precision  cooling products for data centers  and  communications
equipment.   The Company experienced strong demand for its products  across  all
solution applications in 1999.

Foreign  sales  to unaffiliated customers, primarily in Europe,  the  Far  East,
Canada,  and South America, in fiscal year 2000 were $696.2 million or 46.9%  of
net  sales compared to $636.2 million or 47.3% of net sales in fiscal year  1999
and $488.0 million or 43.1% of net sales in fiscal year 1998.  See also note  10
to the consolidated financial statements.

Cost of Goods Sold
Cost  of goods sold was $867.7 million or 58.5% of net sales in fiscal year 2000
compared  to  $747.4 million or 55.6% of net sales in fiscal year  1999.   Gross
margins for fiscal year 2000 were 41.5% of sales, approximately 290 basis points
lower  than  in fiscal year 1999.  The gross margin erosion was associated  with
product  mix shifts to lower margin products, the effect of pro-active  consumer
product  price  cuts  in 2000, and manufacturing inefficiencies  from  continued
global  capacity  expansion.   Our product mix  during  2000  reflected  volumes
shifting  to  the high-end enterprise business, which has a lower  gross  margin
structure than our traditional core business.

Cost  of goods sold was $747.4 million or 55.6% of net sales in fiscal year 1999
compared  to  $645.4 million or 57.1% of net sales in fiscal year  1998.   Gross
margins for fiscal year 1999 were 44.4% of sales, approximately 150 basis points
higher  than  in  fiscal  year 1998.  The improvement was  driven  primarily  by
manufacturing  cost  reductions,  particularly  material  cost  reductions,  the
ongoing  transition of production from the U.S. and Ireland to the  Philippines,
improved  capacity utilization associated with the closure of our  manufacturing
facility  in  Fort  Meyers, Florida, and volume related margin  improvements  in
Silcon and Symmetra products.

Total  inventory  reserves at December 31, 2000 were $20.5 million  compared  to
$17.1 million at December 31, 1999.  APC's reserve estimate methodology involves
quantifying the total inventory position having potential loss exposure, reduced
by an amount reasonably forecasted to be sold, and adjusting its interim reserve
provisioning to cover the net loss exposure.

Segment Results (Refer to note 10 of Notes to the Consolidated Financial
Statements in Item 8 of this Report for important information regarding the
Company's reportable segments)
Net  sales  for  products in the Small Systems segment, which primarily  address
local  and  wide  are networking applications as well as desktop PCs,  increased
2.3% and 14.9% over the prior years in 2000 and 1999, respectively.  The rate of
growth  from  1999 through 2000 was negatively impacted by industry softness  in
the  IT markets, weakening global economies, and maturing markets.  Profits  for
this  segment  have remained relatively stable as a percentage of net  sales  in
spite  of  declining sales growth and pro-active price reductions  during  2000,
principally  due to transitioning the manufacture of certain products  to  lower
cost facilities.

Net  sales  for products in the Large Systems segment, which primarily  provides
large  power  and  availability  solutions for  data  centers,  facilities,  and
communications  equipment, increased 92.0% and 101.3% over the  prior  years  in
2000  and  1999,  respectively.  The Large Systems segment  experienced  healthy
growth  driven by the build-out of data centers and share gains in  the  3-phase
UPS  market with our Silcon products as well as the acquisition of DC-Power  and
precision  cooling  products  for  data centers  and  communications  equipment.
Profits for this segment have declined due to cost inefficiencies resulting from
continued  global  capacity expansion, as well as the  continued  investment  in
product and business development initiatives for this business segment.

Operating Expenses
Marketing,  selling,  general, and administrative (SG&A)  expenses  were  $311.6
million or 21.0% of net sales in 2000 compared to $283.7 million or 21.1% of net
sales in 1999 and $241.0 million or 21.3% of net sales in 1998.  The increase in
total spending in 2000 was due primarily to continued investments in building  a
global relational sales organization.  The increase in 1999 was due primarily to
costs  associated with increased advertising and promotional costs, as  well  as
costs  associated  with  increased  staffing  and  operating  expenses  of   our
marketing, selling, and administrative functions.

During  the  third  and second quarters of 2000, we agreed to license  worldwide
patent  rights relating to uninterruptible power supply technology for  lump-sum
cash  payments of $17.0 million and $48.0 million, respectively, as  more  fully
described in note 11 of Notes to Consolidated Financial Statements in Item 8  of
this  Report.  These license fees were paid from operating cash during the third
and second quarters of 2000.  APC evaluated the portion of the license fees that
represented payment for prior use of the subject technology and the portion that
represented  payment for future use.  Considering each of our  markets  and  the
historical  and  projected revenue realized in markets  utilizing  the  licensed
technology,  we  estimated the present value of royalty  payments,  basing  this
calculation on an appropriate royalty rate and the technology's contribution  to
the overall value of affected products.  Separate present values were calculated
for both historic and projected product sales; the historic values were expensed
and the projected values were capitalized.  Accordingly, write-offs of the fully
paid-up  portions  of the patent licenses were recognized in our  statements  of
income  for the third and second quarters of 2000 as special charges to  pre-tax
earnings  of  $17.5  million and $30.4 million, respectively,  including  direct
expenses of $1.5 million and $1.9 million, respectively.  The remaining balances
of  $1.0  million  and  $19.5 million have been classified on  the  consolidated
balance  sheet  as long term assets and are being amortized on  a  straight-line
basis  over  three  years and nine years, respectively, the estimated  remaining
economic lives of the patent licenses.

The  allowance for bad debts was 6.3% of gross accounts receivable  at  December
31,  2000  compared  to  8.3% at December 31, 1999.  We continue  to  experience
strong collection performance.  Accounts receivable balances outstanding over 60
days  represented  13.4% of total receivables at December 31, 2000  compared  to
9.0%  at  December  31, 1999.  The increase reflects a growing  portion  of  our
business  originating  in  areas  where  longer  payment  terms  are  customary,
including  a  growing contribution from international markets as well  as  large
system  enterprise sales primarily associated with Silcon products.   Write-offs
of  uncollectable accounts represent less than 1% of net sales.  A  majority  of
international customer balances are covered by receivables insurance.

R&D  expenditures were $46.9 million or 3.2% of net sales in 2000, $34.6 million
or  2.6%  of net sales in 1999, and $32.6 million or 2.9% of net sales in  1998.
The  increased R&D spending primarily reflects increased numbers of software and
hardware  engineers  and  costs  associated with  new  product  development  and
engineering support.  The slight decrease as a percentage of sales from 1998  to
1999 was attributable to certain fixed R&D expenses spread over a higher revenue
base.   In  addition,  during  1998 we recorded non-recurring  charges  of  $7.6
million for acquired in-process R&D in connection with its acquisition of Silcon
(see Acquisitions below).

                                       13

Other Income, Net and Income Taxes
Other  income  is  comprised  principally of interest  income,  which  increased
substantially  from  1998 to 2000 due to higher average cash balances  available
for investment during 1999 and 2000.

Excluding  1998  non-tax  deductible charges of $7.6 million  for  acquired  in-
process R&D (see Acquisition section below), our effective income tax rates were
approximately  29.0%,  29.5%, and 30.5%, in 2000, 1999 and  1998,  respectively.
The  decrease  from  1998 to 2000 is due to the tax savings from  an  increasing
portion   of   taxable  earnings  being  generated  from  APC's  operations   in
jurisdictions  currently having a lower income tax rate than  the  present  U.S.
statutory income tax rate.

Effects of Inflation
Management believes that inflation has not had a material effect on APC's
operations.

Liquidity and Financial Resources
Working  capital  at  December 31, 2000 was $754.5 million  compared  to  $706.0
million at December 31, 1999.  APC has been able to increase its working capital
position  as  the  result  of  continued strong operating  results  and  despite
internally  financing the capital investment required to expand  its  operations
and   fund  the  licensing  of  technology  discussed  below.   Our  cash,  cash
equivalents, and short-term investments position decreased to $308.0 million  at
December  31,  2000 from $456.3 million at December 31, 1999, due  primarily  to
outlays  from  operating cash in 2000 related to acquisitions (see  Acquisitions
section  below)  and  the  licensing  of worldwide  patent  rights  relating  to
uninterruptible  power supply technology (see note 11 of Notes  to  Consolidated
Financial Statements in Item 8 of this Report).

Worldwide  inventories were $289.0 million at December 31, 2000, up from  $176.5
million  at  December  31,  1999, due primarily  to  increases  in  on-hand  raw
materials,  to  support  current and anticipated demand  growth  for  enterprise
products, and lower than expected demand in the fourth quarter of 2000, combined
with  $21.3 million in inventory attributable to acquisitions during  2000  (see
Acquisitions  section  below).  Inventory levels as a  percentage  of  quarterly
sales  were 71% in the fourth quarter of 2000, up from 65% in the third  quarter
of 2000 and 45% in the fourth quarter of 1999.

At December 31, 2000, we had $50.0 million available for future borrowings under
an  unsecured line of credit agreement at a floating interest rate equal to  the
bank's  cost of funds rate plus .625% and an additional $15.0 million  and  $7.0
million under unsecured line of credit agreements with a second and third  bank,
respectively,  at similar interest rates.  No borrowings were outstanding  under
these  facilities  at  December  31, 2000.  APC  had  no  significant  financial
commitments,  other  than those required in the normal course  of  business,  at
December 31, 2000.

During  2000 and 1999, our capital expenditures, net of capital grants, amounted
to  approximately  $73.7  million  and $36.0 million,  respectively,  consisting
primarily of manufacturing and office equipment, buildings and improvements, and
purchased  software applications.  The nature and level of capital spending  was
made to improve manufacturing capabilities, principally in the U.S. and the  Far
East;  to upgrade and expand our IT infrastructure; and to support the increased
marketing,  selling,  and  administrative efforts necessitated  by  our  growth.
Substantially all of APC's net capital expenditures were financed from available
operating cash.  We had no material capital commitments at December 31, 2000.

APC  has  agreements  with  the  Industrial Development  Authority  of  Ireland,
otherwise knows as the IDA.  Under these agreements, we receive grant monies for
costs  incurred  for  machinery, equipment, and building  improvements  for  our
Galway  and  Castlebar  facilities.  These grants are  equal  to  40%  and  60%,
respectively, of such costs up to a maximum of $13.1 million for Galway and $1.3
million  for  Castlebar.  Such grant monies are subject to APC  meeting  certain
employment goals and maintaining operations in Ireland until termination of  the
respective  agreements.   Under separate agreements with  the  IDA,  we  receive
direct  reimbursement  of training costs at our Galway and Castlebar  facilities
for  up  to $3,000 and $12,500, respectively, per new employee hired.  See  also
note 14 to the consolidated financial statements.

We  believe  that  current  internal cash flows together  with  available  cash,
available  credit  facilities  or, if needed, the  proceeds  from  the  sale  of
additional  equity, will be sufficient to support anticipated  capital  spending
and other working capital requirements for the foreseeable future.

Acquisitions

Airflow
In  the  fourth quarter of 2000, we acquired privately-held Airflow  Company,  a
Maryland-based  manufacturer of precision cooling equipment  primarily  used  in
data center, Internet, and telecommunications applications.  For Airflow Company
we  paid $22.5 million in cash plus expenses, of which $4.0 million will be paid
at scheduled dates over three years in the event no indemnity claims arise.  Our
cash  outlays associated with the acquisition were financed from operating cash.
At  December 31, 2000, the excess of the purchase price over the estimated  fair
value  of the tangible net assets acquired has been included in goodwill and  is
being  amortized  on a straight-line basis over 15 years.  The  acquisition  has
been  accounted  for  as  a  purchase  and, accordingly,  Airflow's  results  of
operations are included in our consolidated financial statements from  the  date
of acquisition.

Advance Power
Early  in  the second quarter of 2000, we acquired privately-held Advance  Power
Ltd., a U.K.-based manufacturer of DC-power solutions used in communications and
Internet  applications,  for  $75.0 million in cash  plus  expenses.   Our  cash
outlays  associated with the acquisition were financed from operating cash.   At
December  31,  2000,  the excess of the purchase price over the  estimated  fair
value of the tangible net assets and identifiable intangible assets acquired has
been  included in goodwill and is being amortized on a straight-line basis  over
15   years.   The  acquisition  has  been  accounted  for  as  a  purchase  and,
accordingly,  Advance  Power's  results  of  operations  are  included  in   our
consolidated financial statements from the date of acquisition.

ABL Electronics Corporation
Early  in the second quarter of 2000, we acquired privately-held ABL Electronics
Corporation, a North American provider of computer and network cables, switches,
and  other connectivity products, for $8.0 million paid in a combination of cash
and  stock, plus expenses.  Our cash outlays associated with  the
acquisition were financed from operating cash.  At December 31, 2000, the excess
of  the  purchase price over the estimated fair value of the tangible net assets
acquired has been included in goodwill and is being amortized on a straight-line
basis over 15 years.  The acquisition has been accounted for as a purchase  and,
accordingly,  ABL's  results  of operations are  included  in  our  consolidated
financial statements from the date of acquisition.

Silcon A/S
Early  in  the  second quarter of 1998, APC entered into a definitive  agreement
with the principal management shareholders of Silcon to acquire stock of Silcon,
a  Denmark-based  manufacturer of 3-phase UPSs up  to  500  kVA.   In  1998,  we
acquired  89% of the outstanding shares of Silcon, and in January through  March
1999,  we  attained ownership of the remaining Silcon shares.  Our cash  outlays
associated  with  the  step-acquisition of $64.4 million during  1998  and  $8.4
million during 1999 were financed from operating cash.

The purchase price was allocated to the net tangible and identifiable intangible
assets  acquired and to acquired in-process R&D, or acquired R&D.  Acquired  R&D
includes  the value of products in the development stage that are not considered
to  have  reached technological feasibility and that have no alternative  future
uses.   In accordance with applicable accounting rules, acquired R&D is required
to  be expensed.  Accordingly, $7.6 million of the acquisition cost was expensed
in  1998.   The remaining purchase price exceeded the fair value of the tangible
net  assets  acquired by approximately $53.0 million, consisting of identifiable
intangible  assets  and goodwill, which is being amortized  on  a  straight-line
basis over 15 years.  The acquisition has been accounted for as a purchase  and,
accordingly,  Silcon's results of operations are included  in  our  consolidated
financial statements from the dates of acquisition.

Foreign Currency Activity
We  invoice  our  customers  in  various currencies.   Realized  and  unrealized
transaction  gains or losses are included in the results of operations  and  are
measured  based upon the effect of changes in exchange rates on  the  actual  or
expected amount of functional currency cash flows.  Transaction gains and losses
were not material to the results of operations in 2000, 1999 and 1998.

                                       15

At  December  31, 2000, APC's unhedged foreign currency accounts receivable,  by
currency, were as follows:

  
  
  In thousands                      Foreign Currency             US Dollars
                                                           
  European Euros                          38,597                   $35,937
  British Pounds                          14,989                    22,438
  Japanese Yen                         1,942,010                    16,992
  German Marks                            22,396                    10,665
  Swiss Francs                            16,867                    10,285
  French Francs                           54,873                     7,783
  

APC  also had non-trade receivables denominated in Irish Pounds of approximately
US$3.4  million,  liabilities  denominated in  various  European  currencies  of
approximately  US$68.6 million, and liabilities denominated in Japanese  Yen  of
approximately US$8.7 million.

We  continually review our foreign exchange exposure and consider  various  risk
management  techniques, including the netting of foreign currency  receipts  and
disbursements, rate protection agreements with customers/vendors and derivatives
arrangements, including foreign exchange contracts.  We presently do not utilize
rate protection agreements or derivative arrangements.

Recently Issued Accounting Standards
In  June  1998,  the  Financial Accounting Standards Board issued  Statement  of
Financial  Accounting  Standards  (SFAS) No.  133,  "Accounting  for  Derivative
Instruments and Hedging Activities," which establishes accounting and  reporting
standards  for derivative instruments, including certain derivative  instruments
embedded in other contracts (collectively referred to as derivatives),  and  for
hedging  activities.   This Statement is effective for all  fiscal  quarters  of
fiscal  years  beginning after June 15, 2000, as provided for in SFAS  No.  137.
The  adoption of this Statement is not expected to have a material impact on our
consolidated financial position or results of operations.

Factors That May Affect Future Results
This  document  contains  forward-looking  statements  that  involve  risks  and
uncertainties.    Our  actual  results  could  differ  materially   from   those
anticipated in these forward looking statements as a result of certain  factors,
including the risks faced by us described below and elsewhere in this document.

Our quarterly results are likely to be volatile.
Our  quarterly  operating  results may fluctuate as a  result  of  a  number  of
factors, including:
    The growth rates in the UPS industry and related industries, including
     but not limited to the PC, server, networking, telecommunications and
     enterprise hardware industries;
    Timing of orders from, and shipments to, customers;
    Timing of new product introductions and the market acceptance of those
     products;
    Increased competition;
    Changes in manufacturing costs;
    Changes in the mix of product sales;
    Inventory risks due to shifts in market demand;
    Component constraints and shortages;
    Risks of nonpayment of accounts receivable;
    Expansion of manufacturing capacity;
    Factors associated with international operations; and
    Changes in world economic conditions.

                                       16

To  remain  competitive  and expand our growth, we need  to  manage  our  growth
expansion effectively.
We  have  experienced, and are currently experiencing, growth  in  our  business
which  has  placed,  and could continue to place, a significant  strain  on  our
resources.  In order to support the growth of our business, we plan to  continue
expanding  our  level of global operations during 2001.  If  our  management  is
unable  to  manage growth effectively, our operating results could be  adversely
affected.

We  currently compete with several firms providing power protection and  related
products  and  services and expect competition to increase in the future,  which
could affect our revenue and profitability.
We  believe that we are one of less than ten global companies providing  a  full
range  of  UPS  products and services worldwide.  The UPS, power protection  and
related  industries, however, are highly competitive on both a  worldwide  basis
and a regional geographic basis.  We compete, and will continue to compete, with
several  U.S.  and  foreign  firms, both on a worldwide  basis  and  in  various
geographical regions, and within individual product and application niches.   We
expect  competition to increase in the future from existing  competitors  and  a
number  of  companies that may enter our existing or future markets.   Increased
competition  could adversely affect our revenue and profitability through  price
reductions and loss of market share.  The principal competitive factors  in  our
products include:
        Product performance and quality;
        Marketing and access to distribution channels;
        Customer services; and
        Product design and price.

Some  of  our  current  and  potential competitors  have  substantially  greater
financial, technical, sales and marketing resources than we have.  We may not be
able  to continue to compete successfully with our existing competitors or  with
new competitors.

Failure to alter our products to meet the demands of technological innovation
could seriously harm our business.
The  market  for  our products is characterized by rapidly changing  technology,
evolving  industry  standards and frequent new product  introductions.   Current
competitors  or new market entrants may develop new products with features  that
could adversely affect the competitive position of our products.  We may not  be
successful in selecting, developing, manufacturing and marketing new products or
enhancing  our  existing products or in responding effectively to  technological
changes,  new  standards  or product announcements by competitors.   The  timely
availability of new products and enhancements, and their acceptance by customers
are  important to our future success.  Delays in such availability or a lack  of
market acceptance could have an adverse effect on our business.

Defects in our products could seriously harm our business.
Our  products  may  have defects despite testing internally  or  by  current  or
potential  customers.  These defects could result in loss  or  delay  in  market
acceptance,  which  could  have a material adverse  effect  upon  our  business,
operating results, or financial condition.

Loss of any of our key personnel could seriously harm our business.
Our success depends to a significant degree upon the continuing contributions of
key  management,  sales, marketing, research and development  and  manufacturing
personnel, many of whom we would have difficulty replacing. We believe that  our
future  success will depend in large part upon our ability to attract and retain
highly-skilled  hardware  and software engineers,  and  management,  sales,  and
marketing personnel.  Competition for such personnel is intense, and we may  not
be  successful in attracting and retaining such personnel.  Failure  to  attract
and  retain key personnel could have a material adverse effect on our  business,
operating results, or financial condition.

                                       17

Because we depend on foreign operations and revenues, we are exposed to currency
fluctuations,  import  barriers and other risks related  to  conducting  foreign
operations.
We  manufacture  and  market  our  products worldwide  through  several  foreign
subsidiaries, distributors, and resellers.  Our worldwide operations are subject
to  the  risks  normally associated with foreign operations including,  but  not
limited to:
    The disruption of markets;
    Changes in export or import laws;
    Restrictions on currency exchanges;
    Potentially negative tax consequences;
    Longer payment terms;
    Political instability; and
    The modification or introduction or government policies with potentially
     adverse effects.

International  sales,  which  are both direct and indirect  sales  to  customers
outside  the United States, accounted for approximately 46.9%, 47.3%, and  43.1%
of  our  net  sales  in 2000, 1999 and 1998, respectively.  We  anticipate  that
international  sales  will  continue to account for  a  significant  portion  of
revenue.   We invoice our customers in various currencies.  To date, we  do  not
use any rate protection agreements or derivative agreements to hedge any foreign
exchange exposure.  Accordingly, we may be exposed to exchange losses based upon
currency  exchange  rate  fluctuations, which losses  could  have  a  materially
adverse effect on our operating results.

A  significant  portion  of  products in our Small  Systems  and  Large  Systems
reportable operating segments are manufactured in foreign locations.  The  Small
Systems  have  particular  exposure  to the Philippines,  a  country  which  has
experienced  political and financial instability.  Disruption  of  manufacturing
efforts in these international facilities could negatively impact our ability to
fulfill customer orders and potentially result in the loss of business.

Because  our  business  relies  upon a variety of computer  systems  to  operate
effectively,  the failure or disruption of these systems could have  a  material
adverse effect on our business.
APC is a highly automated company whose efficient and effective operation relies
on  a  variety  of  information systems, including e-mail,  enterprise  resource
planning,  electronic  data  interchange, customer resource  management  and  e-
commerce systems.  Disruption in the operation of these systems, or difficulties
in  maintaining or upgrading these systems, could have an adverse effect on  our
business.  In January 2001, we upgraded our enterprise resource planning system.
Difficulties that we have encountered, or may encounter, in connection with  our
implementation  and  use  of this upgraded enterprise resource  planning  system
could adversely affect our order management and fulfillment, financial reporting
and  supply chain management processes, and any such difficulties could  have  a
material adverse effect on our business.

Our reliance on sole source suppliers may result in product delays or price
increases.
We currently obtain some components of our products from single sources.  In the
future,  our  suppliers may not be able to meet our demand for components  in  a
timely and cost-effective manner.  We generally purchase these single or limited
source   components  using  purchase  orders  and  have  no  guaranteed   supply
arrangements with the suppliers.  In addition, the availability of many of these
components  is  dependent in part on our ability to provide the  suppliers  with
accurate  forecasts of our future requirements.  However, our operating  results
and customer relationships could be adversely affected by either an increase  in
prices for, or an interruption or reduction in supply of, any key components.

We have a limited ability to protect our intellectual property rights and others
could infringe on or misappropriate our propriety rights and information.
Our  success  will  depend, to a large extent, on our  ability  to  protect  our
proprietary  technology.  We rely on a combination of contractual rights,  trade
secrets, patents, and copyrights to protect our proprietary rights.  Although we
own  certain patents, and we have applied, and in the future we may  apply,  for
patents,  our intellectual property protection may not be sufficient to  prevent
competitors  from developing similar technology.  Moreover, in  the  absence  of
patent  protection, our business may be adversely affected by competitors  which
independently develop functionally equivalent technology.

Our products may infringe on the intellectual property rights of others.
We  attempt to ensure that our products and processes do not infringe upon third
party  patents and other proprietary rights, but third parties may  allege  such
infringement  in the future.  If third parties allege or determine infringement,
we  may  not  prevail  in  such a challenge.  Furthermore,  if  infringement  is
determined,  we may not be able to obtain the necessary licenses  on  acceptable
terms, if at all.

                                       18

If we are unable to identify and successfully integrate acquisitions, our
ability to expand and our financial results could suffer.
We  have  limited  experience in integrating acquired companies or  technologies
into  our operations.  We may from time to time pursue the acquisition of  other
companies,  assets, products or technologies.  We may not be able  to  integrate
successfully  products, technologies, distribution channels, key  personnel  and
businesses  of  acquired companies into our business or product  offerings.   In
addition,  the  integration  of  acquired companies  may  adversely  affect  our
business,  operating results, or financial condition.  Further,  these  acquired
companies, assets, products or technologies may not contribute significantly  to
our  sales or earnings, and the sales and earnings from acquired businesses  may
be  adversely affected by the integration process or other factors.  If  we  are
not  successful  in the integration of such acquired businesses,  our  financial
results  could  be  adversely impacted.  In addition, we  may  not  be  able  to
identify and consummate suitable acquisition transactions in the future.

Our stock price could be volatile, which could cause you to lose part or all of
your investment.
The market price of our common stock has been, and may continue to be, extremely
volatile.  The trading price of our common stock could be subject to wide
fluctuations in response to:
    Quarter-to-quarter variations in operating results;
    Changes in earnings estimates by analysts;
    Announcements of technological innovations or new products developed by us
     or our competitors; and
    Challenges associated with integration of businesses and other events or
     factors.

In  addition,  the stock market has from time to time experienced extreme  price
and  volume fluctuations which have particularly affected the market  price  for
many  high  technology  companies and which often have  been  unrelated  to  the
operating  performance of these companies.  These broad market fluctuations  may
adversely affect the market price of our common stock.

Our tax rate depends on earnings derived from certain foreign manufacturing
operations.
Our tax rate is heavily dependent upon the proportion of earnings that we derive
from  our  Ireland and Philippines manufacturing operations and our  ability  to
reinvest  those earnings permanently outside the United States.  If the earnings
of  these  operations  as  a percentage of our total earnings  were  to  decline
significantly  from anticipated levels, or should our ability to reinvest  these
earnings be reduced, our effective tax rate would exceed the currently estimated
rate  for  2001.   In  addition, should our intercompany transfer  pricing  with
respect   to  our  Ireland  or  Philippines  manufacturing  operations   require
significant  adjustment  due  to  audits  or  regulatory  changes,  our  overall
effective tax rate could increase.

We have been and may become involved in litigation, which could materially harm
our business.
We  have been and may in the future become, involved in litigation involving our
business,  products  or  operations.  The litigation process  is  uncertain  and
includes  the  risk of an unexpected, unfavorable result.  We may be  materially
adversely impacted by any such litigation.

AMERICAN POWER CONVERSION CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Years ended December 31, 2000, 1999 and 1998


  1.   Summary of Significant Accounting Policies

Nature of Business
American  Power  Conversion  Corporation and its  subsidiaries  (the  "Company")
designs,  develops,  manufactures, and markets power protection  and  management
solutions  for  computer and electronic applications worldwide.   The  Company's
solutions  include  uninterruptible  power supply  products  ("UPSs"),  DC-power
solutions,  electrical  surge protection devices, power  conditioning  products,
precision  cooling equipment and associated software, services, and accessories.
These  solutions  are for use with sensitive electronic devices  which  rely  on
electric utility power including, but not limited to, home electronics, personal
computers ("PCs"), high-performance workstations, servers, networking equipment,
communications  equipment, Internetworking equipment,  data  centers,  mainframe
computers,  and  facilities.   The  Company's principal  markets  are  in  North
America, Europe, and the Far East.

Principles of Consolidation
The  consolidated  financial statements include the accounts of  American  Power
Conversion   Corporation  and  all  of  its  wholly-owned   subsidiaries.    All
significant   intercompany   accounts  and  transactions   are   eliminated   in
consolidation.

Change in Accounting Principle
In  consideration  of  guidance  issued by the  Financial  Accounting  Standards
Board's Emerging Issues Task Force Issue No. 00-10, "Accounting for Shipping and
Handling   Fees   and  Costs,"  the  Company  has  retroactively   changed   its
classification  of  freight  charges billed to  customers  and  related  freight
expenses  from  operating  expenses  to  net  sales  and  cost  of  goods  sold,
respectively.  These changes increased net sales by $10.0 million, $7.7 million,
and  $5.2 million in 2000, 1999 and 1998, respectively, increased cost of  goods
sold  by $30.8 million, $24.7 million, and $24.3 million in 2000, 1999 and 1998,
respectively; and decreased SG&A expenses by $20.8 million, $17.0  million,  and
$19.1 million, in 2000, 1999 and 1998, respectively.  This accounting change had
no impact on reported net income for any of the periods presented.

Revenue Recognition
Revenue  from sales of the Company's products, including UPS products,  DC-power
solutions,  electrical  surge protection devices, power  conditioning  products,
precision  cooling  equipment, and associated accessories,  is  recognized  when
persuasive evidence of an arrangement exists, delivery has occurred,  the  price
to the buyer is fixed or determinable, and collectibility is reasonably assured.
Provisions for sales returns and allowances and uncollectible accounts are  made
at  the  time of sale.  Revenues from the sale of service-related contracts  are
deferred and recognized ratably over an established term, typically one to  five
years.

Cash and Cash Equivalents
Cash  and  cash  equivalents consist of funds on deposit, money  market  savings
accounts,  and  short-term commercial paper with original  maturities  of  three
months or less.

Short Term Investments
At  December 31, 2000, short term investments consisted of U.S. Government  debt
securities with original maturities greater than three months and less  than  or
equal  to  one  year.   Such securities were classified as held-to-maturity  and
carried at amortized cost.  The cost of such securities approximates fair market
value.   Management determines the appropriate classification of debt securities
at  the  time  of purchase and re-evaluates such designation as of each  balance
sheet date.  Debt securities are classified as held-to-maturity when the Company
has the positive intent and ability to hold such securities to maturity.

                                       25

Inventories
Inventories  are  stated at the lower of cost or market; cost  being  determined
using the first-in, first-out (FIFO) method.

Property, Plant, and Equipment
Property, plant, and equipment are stated at cost.  Depreciation is provided  by
using the straight-line method over estimated useful lives as follows:

   
   
                                       
   Land improvements                      15 years
   Buildings and improvements             40 years
   Machinery and equipment                5 - 10 years
   Office equipment, furniture
    and fixtures                          3 - 10 years
   Purchased software                     3 years
   

Goodwill and Other Intangibles
Goodwill  represents the excess of cost over the fair value of the net  tangible
assets  and identifiable intangible assets of businesses acquired and  is  being
amortized  on  a straight-line basis over 15 years.  Periodically,  the  Company
evaluates  the carrying value of goodwill to assure that changes  in  facts  and
circumstances  do  not  suggest that recoverability  has  been  impaired.   This
analysis  relies  on a number of factors, including operating results,  business
plans,  budgets,  economic  projections, and changes in  management's  strategic
direction or market emphasis.  In management's opinion, no impairment exists  at
December  31,  2000.   Goodwill  and  other intangibles  are  presented  net  of
accumulated amortization of $12.2 million and $4.8 million at December 31,  2000
and 1999, respectively.

Research and Development
Expenditures  for research and development ("R&D") are expensed  in  the  period
incurred.

Warranties
The  Company offers limited two-year and one-year warranties.  The provision for
potential liabilities resulting from warranty claims is provided at the time  of
sale.  The Company also offers its customers the opportunity to extend the basic
warranty  period  up  to  an additional three years under  a  separately  priced
program.   Recognition  of  the revenue associated with  the  extended  warranty
program  commences on the date the extended warranty becomes  effective  and  is
recognized  on  a  straight-line basis over the extended  warranty  period.   In
addition, the Company has an Equipment Protection Policy which, depending on the
model,  provides  up to $25,000, 50,000 pounds sterling, or  100,000  euros  for
repair  or  replacement of a customer's hardware should  a  surge  or  lightning
strike  pass  through  a  Company  unit.   The  policy  applies  to  all   units
manufactured  after  January  1,  1992.  Other  restrictions  also  apply.   The
Company's  ProtectNet line of data line surge suppressors feature a  "Double-Up"
Supplemental  Equipment  Protection Policy, under which  the  total  recoverable
limit  under  the  Equipment  Protection Policy is  doubled (U.S. and Canada
only).   The  Company  has experienced satisfactory field operating results, and
warranty costs incurred to date have not had a significant impact on the
Company's results of operations.

Income Taxes
Income taxes are accounted for under the asset and liability method.  Under this
method,  deferred tax assets and liabilities are recognized for the  future  tax
consequences  attributable  to  differences  between  the  financial   statement
carrying  amounts  of existing assets and liabilities and their  respective  tax
bases.  Deferred tax assets and liabilities are measured using enacted tax rates
expected  to  apply  to  taxable income in the years in  which  those  temporary
differences are expected to be recovered or settled.  The effect on deferred tax
assets  and liabilities of a change in tax rates is recognized in income in  the
period that includes the enactment date.

Deferred  income taxes have not been provided for the undistributed earnings  of
the Company's foreign subsidiaries which aggregated approximately $361.0 million
at  December  31,  2000.  The Company plans to reinvest all  such  earnings  for
future  expansion.  If such earnings were distributed, taxes would  increase  by
approximately  $86.0  million.  Additionally, the Company has  tax  holidays  in
China,  India, and the Philippines, which reduce or eliminate the  income  taxes
paid  in  those  countries.   Based on the currently enacted  regular  corporate
income  tax  rates in these countries, the benefit to the Company of  these  tax
holidays was approximately $6.8 million, or $.03 per diluted share, for the year
ended December 31, 2000; $4.5 million, or $.02 per diluted share, for the year
ended December 31, 1999; $2.4 million, or $.01 per diluted share, for the year
ended December 31, 1998.

                                       26

Earnings per Share
Basic  earnings  per share is computed by dividing net income  by  the  weighted
average number of common shares outstanding during the period.  Diluted earnings
per  share is computed by dividing net income by the weighted average number  of
common  shares  and  dilutive  potential common shares  outstanding  during  the
period.  Under the treasury stock method, the unexercised options are assumed to
be  exercised  at  the beginning of the period or at issuance,  if  later.   The
assumed  proceeds are then used to purchase common shares at the average  market
price during the period.  Potential common shares for which inclusion would have
the  effect  of  increasing diluted earnings per share (i.e., antidilutive)  are
excluded from the computation.

Stock-Based Compensation
The Company applies APB Opinion No. 25 and related Interpretations in accounting
for   its  stock-based  compensation  plans.   No  compensation  cost  has  been
recognized   for   these  plans  in  the  accompanying  consolidated   financial
statements.

Advertising Costs
Advertising  costs are expensed as incurred and reported in marketing,  selling,
general, and administrative expenses in the accompanying consolidated statements
of  income.  Such costs of advertising, advertising production, trade shows, and
other  activities  are  designed to enhance demand for the  Company's  products.
Advertising costs were $85.5 million in 2000, $94.4 million in 1999,  and  $67.4
million in 1998.  There are no capitalized advertising costs in the accompanying
consolidated balance sheets.

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


  2.   Acquisitions

Airflow
In  the  fourth  quarter  of 2000, the Company acquired  privately-held  Airflow
Company,  a Maryland-based manufacturer of precision cooling equipment primarily
used  in  data center, Internet, and telecommunications applications, for  $22.5
million  in cash plus expenses, of which $4.0 million will be paid at  scheduled
dates  over  three years in the event no indemnity claims arise.  The  Company's
cash  outlays associated with the acquisition were financed from operating cash.
At  December 31, 2000, the excess of the purchase price over the estimated  fair
value  of the tangible net assets acquired has been included in goodwill and  is
being  amortized  on a straight-line basis over 15 years.  The  acquisition  has
been  accounted  for  as  a  purchase  and, accordingly,  Airflow's  results  of
operations are included in the Company's consolidated financial statements  from
the date of acquisition.

                                       27

Advance Power
Early in the second quarter of 2000, the Company acquired privately-held Advance
Power  Ltd.,  a  U.K.-based manufacturer of DC-based  power  solutions  used  in
communications  and  Internet  applications, for  $75.0  million  in  cash  plus
expenses.   The  Company's  cash outlays associated with  the  acquisition  were
financed  from operating cash.  At December 31, 2000, the excess of the purchase
price  over the estimated fair value of the tangible net assets and identifiable
intangible assets acquired has been included in goodwill and is being  amortized
on  a straight-line basis over 15 years.  The acquisition has been accounted for
as  a  purchase  and,  accordingly, Advance Power's results  of  operations  are
included  in  the Company's consolidated financial statements from the  date  of
acquisition.

ABL Electronics Corporation
Early  in  the  second quarter of 2000, the Company acquired privately-held  ABL
Electronics  Corporation  ("ABL"), a North American  provider  of  computer  and
network cables, switches, and other connectivity products, for $8.0 million paid
in a combination of cash and stock, plus expenses.   The  Company's
cash  outlays associated with the acquisition were financed from operating cash.
At  December 31, 2000, the excess of the purchase price over the estimated  fair
value  of the tangible net assets acquired has been included in goodwill and  is
being  amortized  on a straight-line basis over 15 years.  The  acquisition  has
been  accounted for as a purchase and, accordingly, ABL's results of  operations
are included in the Company's consolidated financial statements from the date of
acquisition.

Silcon A/S
Early  in  the  second quarter of 1998, APC entered into a definitive  agreement
with the principal management shareholders of Silcon to acquire stock of Silcon,
a  Denmark-based  manufacturer of 3-phase UPSs up  to  500  kVA.   In  1998,  we
acquired  89% of the outstanding shares of Silcon, and in January through  March
1999,  we  attained ownership of the remaining Silcon shares.  Our cash  outlays
associated  with  the  step-acquisition of $64.4 million during  1998  and  $8.4
million during 1999 were financed from operating cash.

The purchase price was allocated to the net tangible and identifiable intangible
assets  acquired and to acquired in-process R&D ("acquired R&D").  Acquired  R&D
includes  the value of products in the development stage that are not considered
to  have  reached technological feasibility and that have no alternative  future
uses.   In accordance with applicable accounting rules, acquired R&D is required
to  be expensed.  Accordingly, $7.6 million of the acquisition cost was expensed
in  1998.   The remaining purchase price exceeded the fair value of the tangible
net  assets  acquired by approximately $53 million, consisting  of  identifiable
intangible  assets  and goodwill, which is being amortized  on  a  straight-line
basis over 15 years.  The acquisition has been accounted for as a purchase  and,
accordingly,  Silcon's  results  of operations are  included  in  the  Company's
consolidated financial statements from the date of acquisition.

Pro forma results from operations have not been provided as the acquisitions are
not considered material individually and in the aggregate.


  3.   Special Charges

During  the  third  and second quarters of 2000, the Company agreed  to  license
worldwide patent rights relating to uninterruptible power supply technology  for
lump-sum cash payments of $17.0 million and $48.0 million, respectively.   These
license  fees were paid from operating cash during the third and second quarters
of  2000,  respectively.  The Company evaluated the portion of the license  fees
that represented payment for prior use of the subject technology and the portion
that  represented  payment for future use.  Considering each  of  the  Company's
markets  and the historical and projected revenue realized in markets  utilizing
the  licensed  technology, the Company estimated the present  value  of  royalty
payments,  basing  this  calculation on an  appropriate  royalty  rate  and  the
technology's  contribution to the overall value of affected products.   Separate
present  values  were calculated for both historic and projected product  sales;
the  historic  values were expensed and the projected values  were  capitalized.
Accordingly,  write-offs of the fully paid-up portions of  the  patent  licenses
were  recognized in the Company's statements of income for the third and  second
quarters  of  2000 as special charges to pre-tax earnings of $17.5  million  and
$30.4 million, respectively, including direct expenses of $1.5 million and  $1.9
million, respectively.  The remaining balances of $1.0 million and $19.5 million
have  been classified on the consolidated balance sheet as long term assets  and
are  being  amortized on a straight-line basis over three years and nine  years,
respectively, the estimated remaining economic lives of the patent licenses.

  4.   Accounts Receivable

Accounts  receivable are generally not concentrated in any geographic region  or
industry.   Collateral is usually not required except for certain  international
transactions for which the Company requires letters of credit to secure payment.
The  Company  estimates an allowance for doubtful accounts based on  the  credit
worthiness   of   its   customers  as  well  as  general  economic   conditions.
Consequently,  an  adverse change in those factors could  affect  the  Company's
estimate of its bad debts.


  5.   Inventories

Inventories consist of the following:

  6.   Revolving Credit Agreements and Short Term Debt

At  December 31, 2000 and 1999, the Company had available for future  borrowings
$50.0 million under an unsecured line of credit agreement at a floating interest
rate  equal to the bank's cost of funds rate plus .625%, and an additional $15.0
million and $7.0 million under unsecured line of credit agreements with a second
and  third  bank,  respectively, at similar interest rates.  No borrowings  were
outstanding under these facilities at December 31, 2000 and 1999.


  7.   Income Taxes

Total  federal, state, and foreign income tax expense (benefit) from  continuing
operations for the years ended December 31, 2000, 1999 and 1998 consists of  the

                                       29

Income  tax  expense  attributable to continuing operations  amounted  to  $67.7
million  in  2000, $86.3 million in 1999, and $68.2 million in 1998,  (effective
rates  of 29.0%, 29.5%, and 31.6%, respectively).  The actual expense for  2000,
1999 and 1998 differs from the "expected" tax expense (computed by applying  the
statutory  U.S.  federal  corporate tax rate of 35% to  earnings  before  income
taxes) as follows:

The  domestic and foreign components of earnings before income taxes were $145.3
million  and  $88.0 million, respectively, for 2000; $188.5 million  and  $104.0
million,   respectively,  for  1999;  and  $162.0  million  and  $54.2  million,
respectively,  for 1998.  Total income tax expense for the years ended  December
31, 2000, 1999 and 1998 was allocated as follows:

At December 31, 2000 and 1999, deferred income tax assets and liabilities result
from temporary differences in the recognition of income and expense for tax  and
financial  reporting purposes.  The sources and tax effects of  these  temporary
differences are presented below:

In  assessing  the  realizability of deferred tax assets, the Company  considers
whether it is more likely than not that some portion or all of the deferred  tax
assets  will  not be realized.  Due to the fact that the Company has  sufficient
taxable income in the federal carryback period and anticipates sufficient future
taxable  income  during  the  periods over which the  deferred  tax  assets  are
deductible,  the  ultimate realization of deferred tax assets  for  federal  and
state tax purposes appears more likely than not.


  8.   Stock Plans

Stock-based Compensation Plans
At  December  31,  2000, the Company had four stock option  plans  and  a  stock
purchase  plan, which are described below.  SFAS No. 123, Accounting for  Stock-
Based  Compensation, requires companies to either (a) record compensation  costs
related  to  its stock-based compensation plans, or (b) disclose pro  forma  net
income  and  earnings per share data as if the company had recorded such  costs.
The  Company  has elected to continue to apply APB Opinion No.  25  and  related
Interpretations in accounting for these plans and to comply with  the  SFAS  No.
123  disclosure  requirements.   Accordingly,  no  compensation  cost  has  been
recognized   for   its  stock-based  compensation  plans  in  the   accompanying
consolidated financial statements.  Had compensation costs for such  plans  been
determined  in  accordance  with SFAS No. 123,  the  Company's  net  income  and
earnings  per  share would have been reduced to the pro forma amounts  indicated
below:

 
 
 In thousands except per share amounts             2000                1999               1998

The pro forma effect on net income for 2000, 1999 and 1998 is not representative
of  the pro forma effect on net income in future years because it does not  take
into consideration pro forma compensation expense related to stock option grants
made  prior  to 1995.  The weighted average fair value of stock options  granted
during  2000,  1999  and 1998 was $11.43, $9.35, and $8.84,  respectively.   The
Company  estimates the fair value of each option as of the date of  grant  using
the  Black-Scholes pricing model with the following weighted average assumptions
used for grants in 2000, 1999 and 1998:

 
 
                                    2000                1999                1998

                                       31

Stock Option Plans
On  April  21,  1997, the Company's shareholders approved the 1997 Stock  Option
Plan and on June 19, 1987 approved the 1987 Stock Option Plan (collectively  the
"Plans").  The 1997 and 1987 Stock Option Plans authorized the grant of  options
for  up  to 12.0 million shares and 21.6 million shares, respectively, of common
stock.  On May 7, 1999, the Company's shareholders authorized an additional 12.0
million  shares  under the 1997 Stock Option Plan.  Options  granted  under  the
Plans  are  either  (a) options intended to constitute incentive  stock  options
("ISOs")  under  the  Internal Revenue Code of 1986 (the  "Code")  or  (b)  non-
qualified  options.  Incentive stock options may be granted under the  Plans  to
employees  or officers of the Company.  Non-qualified options may be granted  to
consultants,  directors  (whether  or not  they  are  employees),  employees  or
officers of the Company.
ISOs  granted under the Plans may not be granted at a price less than  the  fair
market  value of the common stock on the date of grant (or 110% of  fair  market
value  in  the case of employees or officers holding 10% or more of  the  voting
stock  of  the Company).  The aggregate fair market value of shares,  for  which
ISOs granted to any employee are exercisable for the first time by such employee
during  any calendar year (under all stock option plans of the Company  and  any
related  corporation), may not exceed $100,000.  Non-qualified  options  granted
under  the  Plan may not be granted at a price less than the lesser of  (a)  the
book  value  per share of common stock as of the end of the fiscal year  of  the
Company  immediately preceding the date of such grant, or (b) 50%  of  the  fair
market value of the common stock on the date of grant.

percent  shareholders).  The outstanding options at December 31, 2000 expire  at
various dates through 2009.  Options granted terminate within a specified period
of  time  following termination of an optionee's employment  or  position  as  a
director or consultant with the Company.

Stock Purchase Plan
On  April  21,  1997,  the  Company's shareholders approved  an  Employee  Stock
Purchase Plan (the "Plan") to provide substantially all employees an opportunity
to  purchase  shares  of  its  common stock through payroll  deductions,  in  an
aggregate  amount up to 10% of eligible compensation.  Semiannually, participant
account  balances are used to purchase shares of stock at the lesser of  85%  of
the  fair  market value of shares on the grant date or the exercise  date.   The
aggregate number of shares purchased by an employee may not exceed 6,000  shares
annually  (subject  to limitations imposed by the Internal Revenue  Code).   The
employee  stock  purchase plan expires on February 11, 2007.   A  total  of  2.0
million  shares are available for purchase under the Plan.  During  2000,  under
the  Plan, 41,671 shares were issued at $18.75 per share and 89,173 shares  were
issued  at  $11.00 per share.  During 1999, under the Plan, 54,706  shares  were
issued  at  $14.03 per share and 53,608 shares were issued at $14.45 per  share.
During  1998, under the Plan, 42,632 shares were issued at $13.44 per share  and
30,626 shares were issued at $10.57 per share.


  9.   Retirement Benefits

Employee Stock Ownership Plans
At  December 31, 2000, the Company had noncontributory Employee Stock  Ownership
Plans  (the  "ESOP") covering substantially all employees in North  America  and
Ireland.   Contributions  to  the ESOP are based on  a  percentage  of  eligible
compensation  and  are determined by the Company's Board  of  Directors  at  its
discretion, subject to the limitations established by U.S. and Ireland tax laws.
The  ESOP  held  8.3 million shares and 8.8 million shares of  common  stock  at
December  31,  2000  and  December  31,  1999,  respectively.   No  shares  were
contributed to the ESOP in 2000, 1999 or 1998.

                                       33

Employee Savings Plan
On  May  1, 1997, the Company established an employee savings plan (the "Savings
Plan")  that qualifies as a deferred salary arrangement under Section 401(k)  of
the  Internal Revenue Code of 1986, as amended, covering substantially all North
American employees.  The Savings Plan allows eligible employees to contribute up
to  15% of their compensation on a pre-tax basis subject to certain limitations.
The Company matches, with Company common stock, 100% of the first 3% of employee
contributions plus 50% of the next 3% of employee contributions.  Employees  are
fully vested in their employer matching contributions.

The Company also sponsors pension plans in several foreign locations.

The  Company's  pension  contributions  in  2000,  1999  and  1998  amounted  to
approximately $4.9 million, $4.3 million, and $1.6 million, respectively.


  10.  Operating Segment and Geographic Information

Segment accounting policies are the same as policies described in note 1.

Basis for presentation

The   Company  operates  primarily  within  one  industry  consisting  of  three
reportable  operating segments by which it manages its business and  from  which
various  offerings  are commonly combined to develop a total  solution  for  the
customer.   These  efforts  primarily incorporate the design,  manufacture,  and
marketing of power protection equipment and related software and accessories for
computer,  communications, and related equipment.  The Company's three  segments
are:   Small Systems, Large Systems, and Other.  Each of these segments  address
global markets.

The  Small  Systems segment develops power solutions for servers and  networking
equipment  commonly used in local area and wide area networks and  for  personal
computers and sensitive electronics.  Major product offerings include the Smart-
UPSr,  Matrix-UPSr, Symmetrar Power Arrayr and Back-UPSr family of  UPSs.   Also
included  are  the  SurgeArrestr  surge  suppressors  as  well  as  cabling  and
connectivity  solutions.   Additional  accessories  and  software  products  are
offered   to  enhance  the  management  of  these  networks.   Products  include
PowerChuter  software,  MasterSwitchT power distribution units  and  NetShelterr
server  enclosures.   Products are sold to home and commercial  users  primarily
through  an  indirect  selling  model consisting of  computer  distributors  and
dealers,  value  added resellers, mass merchandisers, catalog merchandisers,  E-
commerce vendors, and strategic partnerships.

The Large Systems segment produces large system solutions that provide power and
availability   solutions  for  data  centers,  facilities   and   communications
equipment.  Product offerings include Silcon UPSs, NetworkAIR precision  cooling
equipment  and  DC-power  solutions.  Products  are  sold  to  commercial  users
primarily  through an indirect selling model consisting of value added resellers
and strategic partnerships.

The  Other  segment  provides  Web-based  informational,  product,  and  selling
services  as  well as replacement batteries for the Company's UPS  products  and
notebook computers.

In  the fourth quarter of 2000, the Company revised its reportable segments from
prior  periods to reflect management's increased focus on managing the  business
by  small systems, large systems, and other, as a result of acquisitions  during
2000,  changing trends in the market, economic conditions, and increased product
offerings.   Prior periods have been reclassified to reflect the Company's  2000
presentation.

The  Company  measures  the  profitability  of  its  segments  based  on  direct
contribution  margin.  Direct contribution margin includes R&D,  marketing,  and
administrative  expenses  directly attributable to  the  segments  and  excludes
certain  expenses  which  are  managed outside the reportable  segments.   Costs
excluded   from  segment  profit  are  indirect  operating  expenses,  primarily
consisting  of  selling and corporate expenses, and income taxes.   Expenditures
for  additions to long-lived assets are not tracked or reported by the operating
segments,  although  depreciation expense is allocated to and  reported  by  the
operating segments.

The  Company closely monitors the credit worthiness of its customers,  adjusting
credit policies and limits as deemed necessary.  Two customers, Ingram Micro and
Tech   Data  Product  Management,  accounted  for  approximately  14%  and  11%,
respectively, of the Company's net sales in 2000.  No single customer  comprised
10%  or  more  of the Company's net sales in 1999.  One customer, Ingram  Micro,
accounted  for  approximately  11% of the Company's  net  sales  in  1998.   The
majority of the Company's sales to Ingram Micro and Tech Data Product Management
are included in the Small Systems reportable segment.


  11.  Litigation

On  or  about August 20, 1999, General Signal Power Systems, Inc, former  parent
company of Best Power ("General Signal"), filed suit against the Company in  the
United  States  District Court for the Western District  of  Wisconsin  alleging
patent  infringement and false advertising.  General Signal  sought  unspecified
damages,  costs, fees, and injunctive relief.  During March and April 2000,  the
court  dismissed four of the five patent infringement claims.  On or  about  May
12,  2000,  General  Signal  voluntarily  dismissed  with  prejudice  the  false
advertising  claims.   On  May 17, 2000, the parties  agreed  to  the  voluntary
dismissal  of the remaining claim in the lawsuit with prejudice.  In  connection
with  the resolution of this dispute, the Company agreed to license from General
Signal   worldwide  patent  rights  relating  to  uninterruptible  power  supply
technology  for a lump-sum cash payment of $48.0 million.  The license  fee  was
paid from operating cash during the second quarter of 2000.  See also note 3.

On  or about January 27, 1999, the Company was served with a lawsuit filed by an
individual  in  the  United States District Court for the  Central  District  of
California  alleging  patent infringement.  The plaintiff, Anthony  F.  Coppola,
claimed sole ownership of the patent referenced in the lawsuit.  Coppola  sought
unspecified damages, costs, fees, and injunctive relief.  On or about April  14,
1999, the Company removed the case from the United States District Court for the
Central  District  of  California to the United States District  Court  for  the
District  of  Massachusetts.  On September 8, 2000, the parties  agreed  to  the
voluntary  dismissal  of  the lawsuit with prejudice.  In  connection  with  the
resolution  of this dispute, the Company agreed to license from Anthony  Coppola
worldwide patent rights relating to uninterruptible power supply technology  for
a  lump-sum  cash  payment  of $17.0 million.  The license  fee  was  paid  from
operating cash during the third quarter of 2000.  See also note 3.

The  Company is also involved in various claims and legal actions arising in the
ordinary  course of business, some of which claim substantial damages.   In  the
opinion of management, the ultimate disposition of these matters will not have a
material  adverse  effect on the Company's consolidated  financial  position  or
results of operations or liquidity.


  12.  Fair Value of Financial Instruments

The  carrying amounts of cash, cash equivalents, accounts receivable, short-term
debt,  accounts payable, and accrued liabilities approximate their  fair  values
because of the short duration of these instruments.


  13.  Commitments

The   Company  has  several  non-cancelable  operating  leases,  primarily   for
warehousing  and  office space, expiring at various dates through  2007.   These
leases  contain renewal options for periods ranging from one to five  years  and
require  the  Company  to pay its proportionate share of utilities,  taxes,  and
insurance.   Rent expense under these leases for 2000, 1999 and  1998  was  $6.7
million, $4.3 million, and $2.5 million, respectively.

Future minimum lease payments under these non-cancelable leases are: 2001 - $7.7
million; 2002 - $6.0 million; 2003 - $4.3 million; 2004 - $3.9 million,  2005  -
$2.6 million, and $5.0 million thereafter.

                                       36

  14.  Contingencies

The  Company has agreements with the Industrial Development Authority of Ireland
("IDA")  under  which the Company receives grant monies for costs  incurred  for
machinery,  equipment, and building improvements for its  Galway  and  Castlebar
facilities equal to 40% and 60%, respectively, of such costs up to a maximum  of
$13.1 million for Galway and $1.3 million for Castlebar.  Such grant monies  are
subject  to  the  Company  meeting  certain  employment  goals  and  maintaining
operations in Ireland until termination of the respective agreements.  The total
cumulative  amounts  of  capital  grant claims submitted  and  received  through
December  31, 2000 for the Galway facility were approximately $10.6 million  and
$8.0 million, respectively.  The total cumulative amount of capital grant claims
submitted through December 31, 2000 for the Castlebar facility was $.4  million;
no  capital  grant claims had been received for the Castlebar  facility.   Under
separate  agreements with the IDA, the Company receives direct reimbursement  of
training  costs  at its Galway and Castlebar facilities for  up  to  $3,000  and
$12,500, respectively, per new employee hired.  The total cumulative amounts  of
training grant claims submitted and received through December 31, 2000  for  the
Galway  facility were approximately $1.1 million and $1.1 million, respectively.
The  total  cumulative  amount of training grant claims submitted  and  received
through  December  31, 2000 for the Castlebar facility were  approximately  $1.1
million and $.7 million; respectively.

In  addition, the Company executed agreements in 1994 with an unrelated  company
to  acquire  the  280,000  square foot manufacturing and  distribution  facility
presently occupied for one (1) Irish Pound (equivalent to approximately  $1.50).
As  additional consideration for the facility, the Company assumed a  contingent
liability of approximately $5.2 million as part of the Company's agreement  with
the IDA.  The contingent liability is canceled upon successful completion of the
terms of the agreement.


  15.  Quarterly Financial Data (Unaudited)

In  consideration  of  guidance  issued by the  Financial  Accounting  Standards
Board's  Emerging Issues Task Force in Issue No. 00-10, "Accounting for Shipping
and  Handling  Fees and Costs," we have retroactively changed our classification
of  freight  charges  billed  to  customers and related  freight  expenses  from
operating  expenses  to net sales and cost of goods sold,  respectively.   These

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors and Shareholders
American Power Conversion Corporation:


We  have audited the accompanying consolidated balance sheets of American  Power
Conversion  Corporation and subsidiaries as of December 31, 2000 and  1999,  and
the  related consolidated statements of income, changes in shareholders' equity,
and cash flows for each of the years in the three-year period ended December 31,
2000.   These  consolidated financial statements are the responsibility  of  the
Company's  management.  Our responsibility is to express  an  opinion  on  these
consolidated financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in  the  United  States of America.  Those standards require that  we  plan  and
perform  the  audit to obtain reasonable assurance about whether  the  financial
statements are free of material misstatement.  An audit includes examining, on a
test  basis,  evidence supporting the amounts and disclosures in  the  financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by management, as well as  evaluating  the  overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In  our opinion, the consolidated financial statements referred to above present
fairly,  in  all  material respects, the financial position  of  American  Power
Conversion  Corporation and subsidiaries as of December 31, 2000 and  1999,  and
the  results of their operations and their cash flows for each of the  years  in
the  three-year  period ended December 31, 2000, in conformity  with  accounting
principles generally accepted in the United States of America.

The Board of Directors and Shareholders
American Power Conversion Corporation:


Under date of March 15, 2001, we reported on the consolidated balance sheets  of
American  Power Conversion Corporation and subsidiaries as of December 31,  2000
and  1999,  and  the  related  consolidated statements  of  income,  changes  in
shareholders'  equity, and cash flows for each of the years  in  the  three-year
period  ended December 31, 2000, as contained in the annual report on Form  10-K
for  the  year  2000.   In  connection with our  audits  of  the  aforementioned
consolidated  financial  statements,  we  also  audited  the  related  financial
statement  schedule listed in Item 14(a)(2).  This financial statement  schedule
is  the  responsibility of the Company's management.  Our responsibility  is  to
express an opinion on the financial statement schedule based on our audits.

In  our  opinion, such financial statement schedule, when considered in relation
to  the  basic  consolidated financial statements taken  as  a  whole,  presents
fairly, in all material respects, the information set forth therein.
