Company ProfileIncorporated in 1981, American Power Conversion Corporation

(APC) designs, manufactures and markets products that improve

the reliability and productivity of computer systems worldwide

by protecting hardware and data from the ongoing threat of

power disturbances.

Our solutions include surge suppressors, uninterruptible power

supplies (UPSs), power conditioning equipment and related soft-

ware for computer and computer-related equipment. Protected

applications include facilities, sites, mainframe computers, data-

centers, wide area networks (WANs), local area networks (LANs),

Internet and intranet equipment, midrange computers, telecom-

munications equipment, home and office workstations, integrated

services digital network (ISDN) equipment and a variety of con-

sumer electronics.

We also protect these applications against power problems on

data, network, serial, coaxial (CATV) and telephone lines.

C O N T E N T S

1998 was an extremely rewarding year for

APC. We reached the $1 billion milestone,

becoming the first and only company whose

sole focus is power protection to surpass the

$1 billion sales mark.

In an effort to explain some of what was

behind this record year, I will begin by thank-

ing the millions of satisfied APC customers

who have played the central role in our suc-

cess over the years. At APC we always put

the customer first.

I must also thank and congratulate the entire

APC team. Reaching $1 billion is a significant

accomplishment, and every APC employee

should be proud of their role in helping to

further distinguish the Company from the

rest of our industry. I feel privileged to work

with such a dedicated group of people.

I would also like to thank you, our sharehold-

ers, for your continued investment in our

enterprise. In spite of the sometimes wild

fluctuations in the stock market and stock

prices, APC’s focus on long term growth has

paid off. In fact, I take great pride that the

Wall Street Journal recently named APC

stock the third best performing over the last

ten years. Kiplinger’s Personal Finance also

named the Company one of the “Biggest

Winners of the Decade.” APC has been a top

performer over the long term, and we will

continue to apply our formula for success to

our global objectives for continued long-

term returns.

The evolution of networking When APC began selling power protection

equipment, networking was in its infancy.

Most computer users were still transferring

data on the “sneaker net” using 512k floppy

disks. As networking began to evolve, users

began to use linked PCs to share files and

print documents, which gradually increased

the importance of the computers and equip-

ment upon which these tasks were transact-

ed. Still, the number of people protecting the

hardware and data with UPSs was small.

Initially, the motivation for using APC’s prod-

ucts was to protect the hardware itself. As

more and more data was passed across net-

works, our customers began recognizing the

importance and value of the data on their

servers and PCs; they quickly began protect-

ing this data as well. As the value of data grew

“As a company we could not have hoped for a better

business opportunity than one in which network downtime correlates to a loss

of revenue. “

President’s M

essage

President’s Message

President’s M

essage

exponentially, the importance of protecting the

availability of the network reached critical

mass. A growing number of customers cannot

tolerate any downtime in their networks.

In the last few years, the value of the data

being created, transferred and stored has

continued to multiply. Not only is the quan-

tity of data increasing, but E-commerce

applications are literally transferring, pro-

cessing and storing money on the servers

we protect. As a result, highly reliable solu-

tions like our Power Array technology are

being adopted by industry-leading global

enterprises to ensure E-commerce delivers

on its promise.

In 1984, when we built our first UPS, I don’t

think anyone at APC could have imagined a

better scenario for the Company than what we

are seeing today. Data has become money,

and it is flying around the globe, without

bounds, at an incredible rate of speed. As a

company we could not have hoped for a better

business opportunity than one in which net-

work downtime correlates to a loss of revenue.

Global, end-to-end, Nonstop NetworkingIn 1998, with the convergence of data and

revenues in mind, we put many elements of

our objective of providing global, end-to-end,

Nonstop Networking solutions into play.

The acquisition of Silcon™; the continued

introduction of new products for existing and

new markets, geographies and industry

trends; the expansion and development of

strategic relationships; and, the addition of

global manufacturing efforts throughout 1998

all brought us closer to this objective.

One of the many areas of potential growth

for the Company going forward is the

Enterprise or high-power space. In 1998,

our efforts there were bolstered by two

primary factors: the continued roll out and

acceptance of the Symmetra Power Array

and the acquisition of Silcon. Overall,

Symmetra and its Power Array technology

has continued to gain acceptance as the pre-

mier high-availability solution for datacenters.

The three-phase power protection market

addressed by the acquired Silcon products

represents an incremental $1.3 billion in

potential revenue to APC (source: Venture

Development Corporation). We intend to

aggressively pursue these new opportunities

worldwide while we maintain a watchful eye

on the industry trends, customer needs and

new markets that define our objectives.

In closing, I would like to thank you for the

attention you pay our annual report. As

always, we welcome your comments, and

invite you to use the response card enclosed

in the back of the report to relay them to us.

Finally, to the entire APC team, thank you

once again for your admirable dedication,

your unrivaled accomplishments, and the

winning attitude that serves as the founda-

tion for the Company’s continued success.

1998: One billion dollarsIn 1998, we closed our eleventh year as a publiccompany with our eleventh consecutive reportof record revenues. In doing so, we were thefirst company solely dedicated to power protec-tion solutions to surpass the $1 billion annualrevenue mark.

The milestone was reached through a combina-tion of teamwork and our ability to build on thefoundation of our past successes, our reputationfor reliability and our outstanding customer serv-ice. We continued our global efforts to leveragethe strength of our brand, to acquire new cus-tomers and to ensure the satisfaction of thosewho have been loyal to us over the years.

The age of availabilityIn 1988, when the Company went public, many ofthe key applications which drove our business in1998 were either non-existent or virtually unknown.There was no E-commerce, and no computer userwould have considered looking for an InternetService Provider. The concept of a “Browser War”would have been as completely alien as the“World Wide Web.” A few UNIX technophilesknew about the Internet, but America was defi-nitely not online, and Windows was still in itsinfancy. Things have changed.

Today, we see the explosion of technology andthe implosion of the global economy as technolo-gy links the farthest geographic reaches to theportal of our home PCs, and eliminates the histor-ical barriers to trade.

In the future, key technology trends–includingE-commerce, voice over IP (V/IP) and enterpriseresource planning (ERP)–will all depend onunshakable reliability and the availability of infor-mation systems (IS).

These IS trends all represent a paradigm shift in theway the world looks at power protection. Whatbegan as a need to protect hardware, developedinto the need to protect data, and has now culmi-nated in a need to protect availability (see Figure 1).In this age of availability, IS professionals will pushtheir systems as close to 100 percent availabilityas possible because every second of downtimemeans lost revenue and lost business.

APC’s new business strategiesOur plan to provide Nonstop Networking in theage of availability translates into several newbusiness strategies, both internal and external.Our customers are looking for comprehensivesolutions to protect their networks from end-to-end. They are also seeking ways to stay connect-ed, as individuals, to the Internet.

By focusing on end-to-end enterprise solutions,we aim to expand our sales throughout our cus-tomers’ infrastructures. This model also gives usthe opportunity to develop global relationshipswith key accounts. We plan to enter accounts viaa compelling and innovative product, such as aSymmetra Power Array, then expand the sale toother APC solutions from end-to-end.

The growth and importance of the Web will tieinto this Enterprise strategy as the importance ofavailability leads companies to protect all the

pieces of their network. We plan to focus on newsolutions and partnerships to increase attachmentto the internetworking equipment which connectsthe many pieces of a network together.

The need for comprehensive protection is alsopresent in the home, where technology is becom-ing more pervasive. Sub-$1,000 PCs, WebTV andcomputer-operated, networked home appliancesall need power protection. This trend representsanother incremental opportunity for the Companyin the coming years. The trend is especially goodfor APC because it means a larger number ofservers will be needed to support these PCs andadvanced home electronics.

We feel strongly that we should be present wher-ever a potential customer makes the decision topurchase power protection. This translates toexpanded channel opportunity for APC as theway people buy technology changes. First, thedirect PC channel is growing as customers opt topurchase their equipment via the telephone andthe Web. Second, high-power solutions are beingsold through Power VARs who specialize inpower availability consulting. These powerresellers will be especially useful in leveragingthe sale of Symmetra and Silcon units.

These represent just a few of the opportunitieson APC’s horizon. We hope for continued suc-cess as we apply our business formula to theseand other areas of potential growth. As we lookto the new trends and opportunities that defineNonstop Networking in the age of availability, wewill continue to focus on our core competenciesand strive to grow the markets that have broughtus to where we are today and that made 1998such a successful year.

Global In 1998, we witnessed another year of evaporat-ing geographic borders as information and onlinetransactions continued to flow freely throughoutthe globe. At the same time, we continued toconvey our message of Legendary Reliability™ tocomputer users.

At the core of our strategy for global market pen-etration is the fact that we enjoy unmatched glob-al offerings of products, programs and services.Multinational corporations depend on this broad,consistent distribution of solutions to solve theirworldwide availability needs.

Growth and penetrationThe global marketplace during 1998 was filled witheconomic challenges for many companies acrossvarious industries. Instead of retreating in the faceof the challenge, we focused our efforts. We arepleased to report that our business grew in everymajor geographic region on a year-over-year basis.

Supporting this growth was the addition of newfacilities and the expansion of APC’s presenceinto new countries. Our continued global manu-facturing expansion is based on our belief that weshould produce our products where customersare located and to provide them with the mostcost-effective solutions possible.

North and Latin AmericaFor the full year, revenues in the Americas (Northand Latin America) increased 27 percent. Theresults were driven by a healthy U.S. economy andthe continued purchase of IT equipment to supporthigh-availability applications such as the Internetand E-commerce.

“An interruption in the operating voltageof just ten milliseconds in a high-tech production facility such as ours canhave enormous consequences. In chipproduction, it can lay waste to hundredsof man-hours of labor. The regionalpower utility could not guarantee either100 percent reliability of supply nor aconsistency in electrical quality. Thiswas of grave concern to us.

“A solution with the highest reliabilitywas required. Power protection was

critical for both our production plantsand the computer systems. We alsoneeded a steady power supply forlighting, air conditioning and auxiliaryoperating mechanisms.

“The APC Silcon DP300 has solved thisproblem for us. In addition, we arepleasantly surprised by the energy savings, the expandability and environmental friendliness of the APCSilcon DP300. Of course, you alwaysencounter risk when implementing a

In Latin America (LAM), we introduced new Back-UPS® and Smart-UPS solutions which answeredthe need, respectively, for a high-end desktop anda low-end server solution.

Europe, Middle East and AfricaRevenues in Europe, Middle East and Africa(EMEA) were up 38 percent. In 1998, thegrowth was enhanced by the addition of Silcon.With the Danish company came additional man-ufacturing facilities in Denmark, Ireland, Chinaand Switzerland. We also pursued the strategyof widening our product offering, both to opti-mize price points and to fill holes in the productline, with the introduction of new Back-UPS andSmart-UPS solutions.

Japan,Asia and AustraliaIn spite of the lackluster Asian economy, our rev-enues in Japan, Asia and Australia (JPAA) grew 19percent in 1998. Our strong financial position–com-pared to the relatively weak position of local UPScompanies–allowed us to increase our presence inthe region. Our position was further helped by theaddition of new manufacturing facilities in thePhilippines and in China.

To round out our product offering in JPAA, weintroduced a SurgeArrest® (Japan), a Back-UPS andan entry-level Smart-UPS. We also began shippingSymmetra in the region in 1998. Symmetra wasmet with accolades including Softdisk’s “MostRevolutionary Product of 1998” award.

The availability of our tested and proven solutionsallows global IT companies who have selectedAPC to be sure the products they specify for newnetworks are available wherever they do busi-ness. The value to our customers is that theyneed only design their network power architec-ture once, instead of once for each country in

which they do business. This also leads toreduced overhead, installation, training and inte-gration costs. By offering a global solution, wehelp add profit to our customers’ bottom line.

Success in the sales channelIn 1998, we also reinforced our global dedicationto our channel with the expansion and improve-ment of our worldwide reseller partner pro-grams. The programs continue to be custom-tailored to suit the channel needs, channel matu-rity and target demographics of each region. Ourreseller programs are designed to provide train-ing, reduced-price demonstration units and otherselling tools to the resellers responsible for thesale of APC products to our end customers.

Our reseller program continued to be successful aswe attracted new members and participants world-wide. Maintaining our close relationship with ourreseller channel protects our ability to mount suc-cessful product introductions and provides us witha healthy distribution pipeline to support ourdemand creation efforts.

Our channel support efforts were rewarded withacclaim and awards from around the world. Wewere listed in VARBusiness’ “Top 100 Products.”We were also awarded the Computer ResellerNews “Channel Champion” award for the fifthyear in a row in the U.S. We garnered this sameaward in Canada. Internationally, APC was named“Preferred Vendor” by Channels Asia.

Communication and customer satisfactionWe continued to focus on industry-leading effortsin advertising, direct marketing and other brand-building market education activities. One of ourmost comprehensive, global programs involved the1998 World Cup. The World Cup was by far thelargest sporting event of 1998, and no other event

Approaching the next millennium,APC faces new challenges andopportunities, but our ability toapply our core business formulawill be instrumental in our future successes

came close to the global interest it sparked. TheCompany recognized the key opportunity to extendits brand through event sponsorship, and throughprotection of the IT networks supporting the WorldCup. APC’s role was to serve as the last line ofdefense against bad power.

According to Fernand Sastre, co-president ofFrance ’98, “The French Organizing Committeechose APC for its world-wide reputation for prod-uct reliability.” With no trial run, APC helped pro-vide maximum uptime. Nearly 37 billion viewersworldwide didn’t need to worry about missingeven one second of the action.

We also worked diligently to develop our skills inthe arena of online customer support and mar-keting. The APC Web site now offers our cus-tomers E-mail links and a technical referencelibrary which can be accessed from anywhere inthe world. Our customers and resellers havefound our site a valuable information tool. In fact,the number of user sessions has steadilyincreased over the last year, and in January of1999 reached nearly 500,000 for the month.

Our demand creation was effectively backed bystrong customer service and inside sales staff sup-port. These APC employees who spend their timein direct contact with our customers were rankednumber one by Computerworld in an independentstudy. The study rated APC in post-sales support,product knowledge, treatment of the customer,speed of solution, ability to satisfy customerrequests, accuracy of solution, clarity of explana-tion and level of Web innovation. APC was rankedfirst in all but one category.

End-to-EndOur company strategy of closing the availability gapmeans presenting a solution wherever and when-

ever our customers could experience downtime asa result of power problems. In 1998, that strategyled us into several new market spaces. First, wedrove the rapid adoption of our premium categoryof power protection, the Power Array. Second, wemoved into the high-end of the product spectrumwith the acquisition of Silcon and its range of above20kVA products. Third, we paid special attention tothe equipment that lives in the space betweendesktop and server: internetworking gear. Fourth, anew product offering for laptops further openedthat market to the Company. Finally, we roundedout our offering with innovative and comprehen-sive additions to our line of enterprise power management software and accessories.

Symmetra Power Array successWe first entered the high-power space in 1997.Our introduction of the Symmetra Power Arraycreated a new category of power protectiondesigned for high-availability computer datacen-ters. For the first time anywhere, a company wasoffering a fully redundant power protection sys-tem. That meant power protection could operateat availability levels equal to or greater than themost advanced information technology.

As units shipped in EMEA and JPAA, the innova-tion quickly earned APC several major internation-al awards, including Secure Computing “Editor’sChoice.” Symmetra also lead the pack in head-to-head competition. Throughout 1998, Symmetraenjoyed continued success as our premium avail-ability solution.

To complement Symmetra in lower power envi-ronments, and in response to growing demandsfor redundant power protection solutions, theCompany introduced a High Availability RedundantSwitch Package, which uses two APC Smart-UPS, one backing up the other, to ensure con-stant availability.

APC is proud tohave providedthe official powerprotection solutions for thecomputers andsensitive electronics of the1998 World Cup.

High-power markets

Our customers also requested a site-wide enter-prise power protection solution to both comple-ment Symmetra and eclipse the legacy UPSsystems in the 20 to 500 kVA range. In 1998, weaccelerated our entry into this market spacethrough the acquisition of Silcon. Silcon hadalready successfully differentiated itself in thehigh-power space with the kind of technologicalinnovation our customers are accustomed to see-ing from APC.

The high-power solutions in the new APC Silcon

product line are designed to support not just com-

puter systems, but entire buildings. At the other

end of the Silcon spectrum, non-redundant 6, 8,

and 10 kVA products compliment the Symmetra

Power Array line. These new products offer a

good, ultra-efficient solution to our customers

wherever they do not need the premium protec-

tion of a Power Array.

Protection of internetworking gearAlong with the high-power additions to our prod-

uct line, we also focused on providing several

other availability solutions to ensure global, end-

to-end, Nonstop Networking. Some of the most

important and often unprotected equipment on

the network is the internetworking gear that car-

ries data from server to client. When a hub or

router is unavailable due to a power problem, net-

work traffic stops and immediately triggers costly

support and help desk calls. According to Cisco

Systems, “Power-related network downtime is a

business-critical issue which prevents companies

from realizing their financial objectives….” APC is

in a prime position to deal with that issue.

In 1998, we introduced APC PowerStack™, a rack-

mount solution designed to protect hubs, routers

and switches. PowerStack ensures the uptime of

the remote interconnections so critical to the avail-

ability of most networks. This product compli-

mented our existing Smart-UPS rack-mount solu-

tions which serve the continued need to protect

multiple servers housed in rack enclosures like

APC NetShelter®.

The NetShelter itself was enhanced with nearly a

dozen new accessories designed to help our cus-

tomers increase the availability, flexibility and

security of their networks. The complete line of

NetShelter products continue to act as a strong

differentiator in the marketplace.

In fact, because of this continuing migration to the

rack environment, we extended our Smart-UPS

line to include a new rack solution. Introduced late

in the year, the Smart-UPS 5000 was the indus-

try’s slimmest 5kVA rack-mount UPS. It was

designed to protect the increasingly powerful

servers and internetworking products that are

more frequently being housed in one rack.

Complete enterprise coverageBecause end-to-end protection doesn’t stop with

the wide area network (WAN), we gave interna-

tional business travelers a tool to help them breathe

a little easier when plugging notebook computers

into phone and power outlets: the APC SurgeArrest

Notebook Pro. This globally-compatible unit offers

protection against the surges that so often destroy

portable computer modems and motherboards.

Another key component of our high-availability

offering is end-to-end management. In 1998, we

developed a new Web/SNMP management card

which gives network administrators the ability to

manage their APC UPSs via a Web browser or

SNMP management system using a single acces-

sory card. Web and SNMP management are two

leading industry standards for network manage-

ment communications. By combining these two

solutions, we’ve made our customers’ jobs that

much easier.

This accessory is complimented by a suite of soft-

ware developments which demonstrate our con-

tinued leadership in designing and supporting solu-

tions which integrate with customers’ existing sys-

tems. Our software developers work with industry

leaders in network management to develop solu-

tions which integrate seamlessly with the products

our customers already use for network manage-

ment. That way, the task of getting network

administrators to adopt APC solutions is that much

easier. In 1998, we lead the industry by integrating

our software with Tivoli, a leading network man-

agement platform, Cabletron Spectrum, which

specializes in management of internetworking

14

Nonstop N

etworking

gear and TopTools, HP’s proprietary enterprise

management suite. We also enhanced our Web-

based device manager to monitor UPSs in a mixed

operating system environment. Leveraging the

customer’s existing investment, whether operat-

ing system or management software, instead of

forcing them to adopt a new and different solution,

helps make APC the easy choice.

Nonstop NetworkingComputer networks are rapidly connecting every-

thing and everyone around the globe. The avail-

ability of these networks is directly linked to the

profitability, productivity and public image of every

company that chooses to be connected. Whether

the purpose of being online is brand-building, E-

commerce or information distribution, when the

connection fails, the bottom line suffers.

The dynamics of dataWith every new connection, the role of data in busi-

ness is changing. Not long ago, a company’s data

pool was primarily a historical reference point. That

point is now a moving target; data capture and dis-

tribution has become a real-time, global flood.

Customers demand instantaneous response. For

companies, the threat of competition requires

total, up-to-the-second awareness of customer

needs. Meanwhile, the volume of data has

changed the role of IS from data collection and pro-

cessing to revenue capture. Where data was once

used to drive revenues, E-commerce has trans-

formed the data into actual revenues. In business,

availability is everything because data is everything.

The need for Nonstop Networking in this data-

intensive world drives the APC vision and mission.

Our vision is to have APC products ensuring avail-

ability wherever data is created, transmitted or

stored. In support of our vision, our mission is to

create delighted customers by improving the man-

ageability, availability and performance of informa-

tion and communication systems through the rapid

delivery of innovative solutions to real customer

problems. Understanding the industry trends and

staying ahead of the curve in terms of solution

development is critical to APC’s success.

Internet explosionIn four short years, the Internet captured more

than 50,000,000 users worldwide, and this

omnipresent communication system’s growth

continues to be strong. The two other communi-

cation breakthroughs of this century, television

and radio, showed only a fraction of the adoption

rate of the Internet. Also consider the fact that the

Internet, unlike TV and radio, is interactive and

capable of supporting not only data, but voice and

visual communications as well. This year the

Internet truly entered the mainstream, with the

rapid acceptance and proliferation of Internet trad-

ing, E-commerce and the remarkably popular

Internet PCs.

The world’s largest cash registerFocus for a moment on the fact that the Internet is

a giant cash register capable of performing billions

of transactions per day. Already, billions of dollars

in sales have been conducted over the Internet.

Add in the fact that this cash register and store-

front is available to virtually anyone, anywhere,

and the possibilities of using the Internet as a rev-

enue stream are virtually endless. Demand, an

Internet connection and a few keystrokes are all

that’s required of a customer to make a purchase.

In addition, compared to a cash or even a credit-

based economy, Internet customer transactions

produce a phenomenal quantity of data. Web sites

plug right into data warehouses which allow com-

panies to conduct sophisticated global analysis.

The first question all this data can answer is,

“What type of person wants to buy my product?”

Once a company has processed an accurate cus-

tomer profile, they’ll have a good idea what key

traits indicate a high likelihood that such a person

would buy the product. The next logical step is to

search other data warehouses globally to find

new contacts who demonstrate those key traits.

Finally, they can begin marketing to and acquiring

these new customers. The process of identifying

and closing opportunities is now an automated,

statistical science.

Because Internet store hours are, by definition,

24-hours a day, seven days a week, 365 days a

year, the collection of these new opportunities is

dramatically enhanced. As the data pours in and

the customer analysis is applied, the flow of rev-

enue becomes a matter of percentages.

Availability increases the ability to collect opportu-

nity at the top of the funnel and correlates direct-

ly to revenues at the bottom.

A power outage, data loss and hardware damage

can all but close the doors of a successful Internet

store. APC’s role in solving the first problem is

clear–instant battery back-up. Recent studies have

shown that more than 45 percent of all data loss is

the result of bad power and that 25 percent of the

CPUs destroyed every year are victims of bad

power (Sources: Contingency Planning/Safeware).

Billions of dollars are spent every year on technol-

ogy to ensure those stores stay open for business,

and many millions are spent on APC power pro-

tection to ensure the same. Those businesses that

depend on E-commerce simply cannot afford net-

work downtime.

Reinventing the telephoneLikewise, as voice over IP (V/IP) continues to

grow as a viable alternative to telephone service,

customers will demand the reliability they have

come to expect from their phones. Telephone

systems use both surge suppressors and UPSs

throughout their networks. The only way V/IP will

be able to compete with telephone service is if

the networks provide comparable availability. In

other words, these networks must avoid the

impact of power problems.

Even if clients and servers are up and running,

networks depend on hubs and routers to maintain

the communication links. With data transfers, a

“buffer” is built into the system so that if an oper-

ation “times out” because a piece of the network

is unavailable, the operation can sometimes con-

tinue after a temporary delay. Real-time voice

communication depends on constant availability,

and users will not tolerate being timed-out or

forced to wait to speak.

Protecting the enterpriseAnother major IS trend driving the need for con-

stant availability is enterprise resource planning

(ERP). Core business processes are being auto-

mated and distributed via networks to employees

around the world. The productivity and profitability

of a company is directly linked to the ERP sys-

tems that support the business. These systems

include accounting, E-mail, E-commerce, order-

taking and many other critical systems. When

they stop, the business stops.

APC has taken a leadership role in offering ERP

integration. We protect corporate productivity

with automatic safe shutdown of Microsoft

BackOffice and Lotus Notes. APC also integrates

with and protects financial applications and plat-

forms such as Oracle and SAP/R3. By protecting

all levels of our customers’ business through inte-

gration with industry-leading ERP solutions, we

successfully differentiate ourselves from the rest

of the industry.

Whatever the application, power protection is a critical

element in the quest for the highest levels of network

availability. In 1998, that impact of bad power on net-

works was very real. A recent analysis of a global data-

com network demonstrated that power problems had

nearly five times the impact of the next leading problem.

The mean time to repair for those problems was nearly

three and a half hours. APC is in a key position to pre-

vent these problems from affecting business and to

define Nonstop Networking in the process.

In 1998, as network availability moved to center

stage, we saw more and more industry leaders rec-

ommending APC solutions as a critical piece of

their end-to-end network architecture. IT manufac-

turers, industry experts and IT professionals con-

tinue to point toward the importance of power pro-

tection for PCs, servers and datacenters. During

the year we enjoyed the support of these leaders

as they either bundled, recommended or helped

develop new solutions.

NEC Japan recommended APC on the desktop

and named APC the vendor of choice for their

Express Server line. Meanwhile, Dell bundled

PowerNet® Manager for NT with PowerEdge

Servers 2200, 4200 & 6100. Helping to increase

our worldwide exposure, HP selected APC for

scalable NT Enterprise server solutions (LXr Pro8

system) in EMEA, offered Smart-UPS bundle pro-

16

Nonstop N

etworking

mos in China, and shipped a promotional

ProtectNet® with servers in EMEA. Continuing

this trend of a global standardized solution, IBM

offered Smart-UPS 620 for RS/6000 workstations

and APC UPSs for select IBM RS/6000 servers in

EMEA. IBM had already made APC power pro-

tection solutions available for RS/6000 servers in

North America (NAM), LAM and JPAA.

Siemens, emphasizing the importance of maxi-

mum availability in telecom applications, added

APC’s Symmetra Power Array to the list of APC

solutions they offer. Also at the enterprise level,

Sun selected Symmetra for Starfire servers, and

tested and qualified Smart-UPS 1000 for their

Enterprise 250 server.

As more and more importance was placed on inter-

networking gear, APC integrated with CiscoWorks

2000, while Nortel selected APC to protect the

BayStack line of internetworking equipment.

Power availability: the weakest linkIn spite of the flood of technological advance-

ments seen in the high-tech industry over the last

year, the reliable supply of electricity continues to

require the intervention of battery back-up power

and surge suppression. Many factors impact

power delivery, but few are as visible and lasting

as the weather. The year began with a bang as ice

storms ravaged the northern part of the North

American continent and caused major outages.

The need to bring in crews from all over the U.S.

and Canada to assist with repairs once again raised

the issue of the growing impact of deregulation on

utility companies’ ability to staff for contingencies.

On December 24, 1998 thousands of consumers

in the mid-Atlantic states suffered a serious blow

at the hands of Mother Nature. An unprecedent-

ed ice storm caused an eight-day outage, in spite

of advance preparations by the utility company

serving the region.

According to the Richmond Times-Dispatch, “The

silver lining in this coat of ice is awareness. It

should focus attention on whether enough safe-

guards are in place after deregulation to deal with

a widespread power outage.“

In many instances, utilities can provide power to

customers 99.977 percent of the time. This trans-

lates to 1.927 hours per year of downtime. At first

look, that means the power company would leave

the top MIS managers only a few hundredths of a

percent short of their goal of 99.999 percent

based on power availability alone.

Unfortunately, no matter how consistent the utility

power output is, power delivery holds its own set

of challenges over which the utilities have no con-

trol. The utility reliability figures are calculated dur-

ing normal conditions and do not include these inci-

dents and “acts of God” that are out of the utilities’

control. In the case of the Christmas Eve ice storm

mentioned above, the actual downtime was more

than a week. Companies that depend on IS, and

who carefully plan against downtime, must take

these uncontrollable outages into consideration. A

more accurate metric of total power availability is

the sum of downtime caused by all factors affect-

ing power from creation to delivery.

Just not enoughWhile the jury is still out on the impact of deregu-

lation on power availability, the need for power

protection as part of any contingency plan is clear.

During the past year, lengthy outages in New

Zealand, continued poor power quality in develop-

ing regions like India and China, and recent reports

published in the U.S. and Canada indicate that the

best course for businesses anywhere in the world

is to expect outages.

Even the most reliable utility companies in the

U.S. regularly fall short of the 99.999 percent

availability sought by IT managers. IT equipment

depends on power to function, and without a

back-up power supply, these systems are only as

capable as their weakest link. In many cases that

means the power coming out of the wall.

Assessing the IS impact worldwideTo make matters worse, little or no worldwide util-

ity availability reporting criteria have been estab-

lished. Many of the utility reliability estimates fail

to account for outages of five-seconds or shorter

duration, while some draw the line at one second.

In fact, only a few states or countries require any

kind of public disclosure at all.

For network managers concerned about availability,

the task of tracking down the source and impact

of bad power is difficult to say the least. They

must begin with published utility downtime (if it is

published). Then they need to add in potential out-

ages due to:

● local weather; ● problems with the local power grid and dis-tribution system (which, due to deregula-tion, may or may not be managed by theutility providing the power);

● site characteristics (i.e., internal buildingwiring problems);

● and, planned downtime due to mainte-nance and construction.

The actual impact is then calculated based on:

● total user downtime and recovery time;● session losses (i.e., connections breaking inthe middle of a data transfer);

● help desk and service calls;● lost revenue;● and, worse, lost customers.

As you can see, the initial downtime factors cre-

ate a powerful “ripple effect” (see Figure 3)

which can quickly send costs skyrocketing.

Because so many of the factors are unpre-

dictable, the network manager must plan for and

prevent all of them to ensure reliability. APC is

positioned to assist at every point on the network

susceptible to power problems.

According to Contingency Planning, mission-critical

business application downtime can cost as much

as $6.45 million per hour (see Figure 4, p. 20 ). That

revenue exposure is at the core of the quest for

99.999 percent systems availability. If a utility

claims that two hours per year, excluding momen-

tary outages and acts of God, represent their peak

utility availability performance, it doesn’t take

much math to figure out just how quickly power

protection pays for itself.

Potential impact of Y2K on utility powerIn 1998, it seemed like everyone was talking

about Y2K and the full spectrum of its possible

impact on the world. Ranging from all out panic to

complete indifference, the consensus by year’s

end seemed to drift toward a cautious optimism

mixed with concern. The most recent report deliv-

ered by the North American Electric Reliability

Council (NERC) indicates a high probability that

the utility system won’t suffer a major interruption

of service as a result of the Y2K problem.

In spite of this good news, however, NERC does

recommend that “customers with electrical

demands essential to safety and public well-being

…[and] large commercial and industrial customers

that would be severely impacted by an electrical

outage, should review their emergency power

supply provisions and procedures, and coordinate

their needs with the local electricity provider.”

In sum, no one knows what the the future will

hold, but a recent APC survey of its customers

indicated that 78 percent of those surveyed have

included power protection in their Y2K contin-

gency plan. The same survey indicated a full 46

percent plan to purchase additional power protec-

tion in the next 12 months as part of that plan.

Most interesting from APC’s perspective is the

heightened level of overall awareness of the

importance of power protection. Even the process

of discussing the impact of Y2K on the utility

industry has many people in the press talking

about power problems in general. Dean Wolfe,

business editor of Network Magazine, had this to

say in his February, 1999 column:

“While amidst all the hair pulling and teeth gnash-

ing over Y2K readiness, don’t forget that a less

high-profile (and unforeseen) emergency could be

just as damaging to your network and IT systems.

The point was reinforced for me in December 1998

when Network Magazine’s editorial offices were

knocked offline by a massive power outage in the

San Francisco Bay Area. Your contingency plan

should be broad and collaborative. The network

department may have its house in order, but what

happens if the power goes down? Do you have a

plan to keep your server room from overheating?

What if you lose power and phone service?”

Meanwhile, the international outlook with regards

to the Y2K and utility power picture is much less

clear and in some cases much more ominous. The

government of the United Kingdom, one of the

few other Western nations with privatized utility

power, was feeling pressure from the private sec-

tor to provide details regarding Y2K readiness of

the power grid. As a result the government’s

Office of Electricity (OFFER) commissioned an

independent assessment of the electricity indus-

try’s Y2K readiness.

More drastic are the plans put in place by Dutch

energy officials. Uncomfortable with the progress

of its neighbors with regard to Y2K, the Dutch

government is adopting a policy of utility isola-

tionism designed to protect the stability of their

own grid. According to a recent report issued by

the International Trade Administration at the

United States Department of State, “As part of a

contingency plan for the sector, the Dutch nation-

al power grid will be disconnected from the inter-

national grid before the turn of the century.”

The impact could be greater in nations where the

resources to repair the millennium bug are simply

not available. Companies doing business in these

less stable regions will be forced to implement

more extreme contingency plans, many of which

should include power protection.

Overall, it is unclear what impact Y2K fears will

have on UPS buyers, but we welcome the

increased awareness of the potential impact of

power problems, and expect not every country will

ride into the next millennium without a few bumps.

In conclusion, through both innovation and acqui-sition, APC continued, in 1998, to meet cus-tomer demand for solutions that enhance theavailability of information systems. These effortsmoved us dramatically closer to our goal of pro-viding global, end-to-end, Nonstop Networkingsolutions to our customers.

Part I

Item 1. Description of Business

The CompanyAmerican Power Conversion Corporation and its sub-sidiaries (the “Company”) designs, develops, manufac-tures, and markets power protection and managementsolutions for computer and electronic applications world-wide. The Company’s solutions include uninterruptiblepower supply products (“UPS”), electrical surge protectiondevices, power conditioning products, and associated soft-ware, services, and accessories. These solutions are foruse with sensitive electronic devices which rely on electricutility power including, but not limited to, home electronics,personal computers (“PCs”), high performance worksta-tions, servers, networking equipment, telecommunicationsequipment, internetworking equipment, datacenters, main-frame computers, and facilities.

The Company's UPS products regulate the flow of utilitypower to ensure safe and clean power to the protectedequipment and provide seamless backup power in theevent of the loss of utility power. The backup power lastsfor a period of time sufficient to enable the user to continuecomputer operations, conduct an orderly shutdown of theprotected equipment, preserve data, work through shortpower outages or, in some cases, continue operating forseveral hours or even days. The Company's surge protec-tion devices and power conditioning products provide pro-tection from electrical power surges and noise in the flowof utility power. The Company’s software and accessorysolutions enhance monitoring, management, and perform-ance of APC’s UPS products. The Company’s service offer-ings assist the end-user with installation and maintenanceof the Company’s UPS products.

The Company markets its products to business and homeusers around the world through a variety of distribution chan-nels, including computer distributors and dealers, valueadded resellers, mass merchandisers, catalog merchandis-ers, E-commerce vendors, and strategic partnerships.

The Company was incorporated under the laws of theCommonwealth of Massachusetts on March 11, 1981. TheCompany's executive offices are located at 132 FairgroundsRoad, West Kingston, RI 02892 and its telephone number is(401) 789-5735.

Acquisition of Silcon A/SEarly in the second quarter of 1998, the Company enteredinto a definitive agreement with the principal managementshareholders of Silcon A/S (“Silcon”) to acquire stock ofSilcon, a Denmark-based manufacturer of three-phaseUPSs up to 480 kilo volt-amps (“kVA”), and the Companycommenced a tender offer for Silcon shares. In June 1998,the initial tender offer and purchase of stock from principal

management shareholders was completed enabling theCompany to operate Silcon as a majority-owned subsidiary.During the second half of 1998, the Company increased itsownership percentage to 89%. The Company’s 1998 cashoutlays associated with the acquisition aggregating $64 mil-lion were financed from operating cash. In January 1999,the Company attained ownership of more than 90% of theshare capital of Silcon through open market purchasesfinanced from operating cash and commenced a mandatoryredemption of the remaining Silcon shares. Through thismandatory share redemption process, the Company antici-pates that it will complete its acquisition of the remainingoutstanding shares of Silcon during the second half of 1999.In connection with the mandatory redemption, theCopenhagen Stock Exchange has approved the de-listing ofSilcon’s shares effective March 1, 1999. See also the“Acquisition” section included in Management’s Discussionand Analysis of Financial Condition and Results ofOperations in Item 7 of this Report.

Market OverviewThe growth of the UPS industry has been fueled by therapid proliferation of microprocessor-based equipment andrelated systems in the corporate marketplace and in thesmall office / home office (“SOHO”) environment. PCs andservers have become an integral part of the overall businessstrategy of many organizations as well as in many technical,scientific, and manufacturing settings. Businesses continueto implement and run their operations via local area andwide area networks (“LANs” and “WANs”) as well as viacorporate intranets and the Internet. Businesses are alsobecoming aware of the need to protect devices such asswitches, hubs, routers, bridges, and other “smart” devicesthat manage and interconnect networks. It is necessary toprotect both the hardware and data stored in and travelingthrough these networks as well as to provide battery back-up to enhance productivity through the high availability ofnetworks, sensitive electronics and even facilities.

The Company believes that the increased awareness of thecosts and lost productivity associated with poor power qual-ity has increased demand for power protection products.Complete failures, surges, or sags in the electrical powersupplied by a utility can cause computers and related elec-tronic systems to malfunction, resulting in costly downtime,damaged or lost data files, and damaged hardware. A UPSprotects against these power disturbances by providingcontinuous power automatically and virtually instantaneous-ly after the electric power supply is interrupted, as well asline filtering and protection against surges or sags while theelectric utility is operating. A UPS can draw on the energystored in its internal battery to provide continuous, clean,computer power. In international regions power qualityoften results in varied levels of distortions and, as a result,these areas provide the Company with additional opportuni-ties for its products.

In 1998, the Company focused on providing global, end-to-end, Nonstop Networking solutions for the PC, server, data-

usiness

center and enterprise markets. The acquisition of Silconexpanded the scope of the Company’s product reach,enabling it to address incremental segments of the UPSmarket, i.e., the larger than 16 kVA or enterprise segmentthat it was not previously addressing. Major global trendsaffecting the Company’s business in 1998 included the con-tinued global proliferation of servers and information tech-nology (“IT”) equipment, including those for Internet andintranet applications; the growth of PC sales; and the con-tinued poor and unreliable quality of power worldwide.

The Company’s goal is to leverage these trends, to targetthe sales of UPSs with new IT equipment, to have theproducts and presence to succeed in new geographies,and to continue to position itself as the UPS and power pro-tection solution provider of choice. The Company also con-tinues to target promotional efforts at the corporate, home,and SOHO PC markets, which it has identified as growthopportunities for the future, and continues to target indus-tries that are becoming more dependent on electronic sys-tems, such as the telecommunications industry, as poten-tial market growth opportunities.

Products

The Company's strategy is to design and manufactureproducts which incorporate high-performance and qualityat competitive prices. The Company’s products aredesigned to fit seamlessly into the computer and network-ing environments of businesses, homes, and SOHOs.These products are engineered and extensively tested forcompatibility with leading PC, server, datacenter, andenterprise hardware and software.

The Company currently manufactures a broad range of stan-dard domestic and international power protection solutions.The Company’s UPS models are designed for different appli-cations with the principal differences among the productsbeing the amount of power which can be supplied during anoutage, the length of time for which battery power can besupplied (the “run time”), the level of intelligent networkinterfacing capability, and the number of brownout and over-voltage correction features. The Company's present line ofUPS products ranges from 200 volt-amps (suitable for a PC)to 480 kVA (suitable for mainframe computers or facilities).List prices to end-users range from approximately $100 toapproximately $200,000. The Company also offersSurgeArrest®, PowerManager™, and ProtectNet® productsto protect against power spikes and surges. The principal dif-ference among the surge suppressor models is the level ofprotection available and feature sets. List prices to end-usersrange from approximately $25 to approximately $135.

The Company also develops a family of software productsunder the PowerChute® plus name which provides its userswith unattended shutdown capabilities, UPS power man-agement, and diagnostic features. PowerChute plus is avail-

able free of charge for many major operating systems withthe purchase of select UPS units from the Company. Listprices to end-users for other PowerChute products start at$69. The Company also offers software packages foradvanced monitoring, configuring, and managing of powerresources. Select versions are available free of charge fromthe Company. List prices range from $169 to $499.

In addition, the Company offers a range of complimentaryaccessory products designed to enhance the functionalityof the Company’s UPS and surge protection products.NetShelter® is a high-quality, free-standing enclosure forstoring and protecting network, internetworking, and powerprotection equipment. Other accessories offered by theCompany include MasterSwitch™ which provides remoteWeb/SNMP management and control of power to attachednetwork devices; PowerView™ for display of a UPS’s oper-ational status; Share-UPS® for reliable shutdown of multi-ple servers connected to a single UPS; SmartSlot™adapters designed to fully integrate with APC Smart-UPS®,Matrix UPS®, and Symmetra™ Power Array™ systems foradvanced UPS and environmental management; and cus-tomized cables for enhanced management and monitoringof APC UPSs. List prices to end-users for accessory prod-ucts range from $75 to $1,999.

Service ProgramsThe Company provides service programs to its customersfor in-warranty UPS products and out-of-warranty UPS prod-ucts, as well as for product installation and start-up. TheCompany offers two-year and one-year limited warrantiescovering its UPS products. The Company also offers its cus-tomers the opportunity to extend the basic warranty period,at an additional charge, for a period of one or three addi-tional years. In-warranty service programs allow customersto return their original unit for repair and, if found defective,the Company will replace the original unit with a factoryreconditioned unit or, if requested, repair the original unitand return it to the customer. The extended warranty can bepurchased anytime during the standard warranty period. Fora fixed fee (varying by model), the Company will replace anout-of-warranty UPS unit with a factory reconditioned unit.The Company offers a standard one year warranty whichcovers certain Silcon product parts. This warranty can beextended in annual increments for a period not to exceedten years. Additionally, the Company offers on-site serviceand preventative maintenance visits for Silcon systems.The Company offers on-site service through APC’s servicedepartment and third party vendors as well as Trade-UPSprograms for customers to upgrade old APC or competitiveunits to new APC units. The Company offers PowerAudit®,an on-site power quality consulting service which analyzesthe electrical infrastructure of a building to determine itssuitability for a given business and to identify corrections toexisting anomalies.

The Company offers an Equipment Protection Policy (U.S.and Canada only) which provides up to $25,000 for repair orreplacement of customers' hardware should a surge orlightning strike pass through a Company unit. The policyapplies to all units manufactured after January 1, 1992.Other restrictions also apply. The Company’s customerscan also register the ProtectNet line of data line surge sup-pressors for a “Double-Up” Supplemental EquipmentProtection Policy, under which the total recoverable limitunder the Equipment Protection policy is doubled, up to$50,000. Most of the Company’s surge suppressor prod-ucts come with a lifetime product warranty.

The Company’s products have experienced satisfactoryfield operating results, and warranty costs incurred to datehave not had a significant impact on the Company's con-solidated results of operations.

Distribution Channels

The Company markets its products to businesses, homeusers, and SOHOs around the world through a variety ofdistribution channels, including computer distributors anddealers, value added resellers, mass merchandisers, cata-log merchandisers, E-commerce vendors and strategicpartnerships. The Company also sells directly to some largevalue added resellers, which typically integrate theCompany’s products into specialized microcomputer sys-tems and then market turnkey systems to selected verticalmarkets. Additionally, the Company sells certain selectproducts directly to manufacturers for incorporation intoproducts manufactured or packaged by them.

In 1998 and 1997, one customer accounted for approxi-mately 11% and 10%, respectively, of the Company’s netsales. In 1996, no single customer comprised 10% or moreof the Company’s net sales.

Sales and Marketing

The Company’s sales and marketing organizations are pri-marily responsible for four activities: sales, marketing, cus-tomer service, and technical support. The Company’s salesstaff is responsible for relationships with distributors, deal-ers, strategic partners and end users as well as developingnew distribution channels, particularly in geographic andproduct application areas into which the Company isexpanding. The Company’s sales force focuses on the cus-tomer through customer units dedicated to specific cus-tomer groups. The Company has charged its sales forcewith providing its customers with comprehensive productand service solutions to their power management needs.

The Company’s marketing activities include marketresearch, product planning, trade shows, sales and pricingstrategies, and product sales literature. The Company alsoutilizes direct marketing efforts domestically and interna-tionally, including direct mailings and print, online/Internet,radio, and television advertising, as well as exhibiting at

computer trade shows. Customer service is responsible forall technical marketing inquiries and customer support. TheCompany has developed a number of programs and tech-niques to support the Company’s distribution channels.These include, but are not limited to, toll-free phone assis-tance, online product and technical information, formalproduct demonstrations, and reseller trainings.

Manufacturing, Quality Control, and SupplyThe Company’s manufacturing operations are located in theUnited States, Ireland, the Philippines, China, Denmark,and Switzerland. The Company believes that its long-termsuccess depends on, among other things, its ability to con-trol its costs. The Company utilizes state-of-the-art auto-mated manufacturing techniques and extensive qualitycontrol in order to minimize costs and maximize productreliability. In addition, the design of products and the com-monality of parts allow for efficient circuit board componentinsertion, wave soldering, and in-process testing. Qualitycontrol procedures are performed at the component, sub-assembly, and finished product levels.

The Company is committed to an ongoing effort to enhancethe overall productivity of its manufacturing facilities. TheCompany uses lean, “cell” based manufacturing processes.Such processes have been implemented in the Company’sU.S. facilities as well as a majority of its international locations.

National Quality Assurance has granted the Company itsISO 9000 quality seal. The Company’s systems have beenaudited to the stringent ISO 9002 level at its manufacturingfacilities in the United States, Galway, Ireland, and at two ofits facilities in the Philippines. Additionally, its Denmarkmanufacturing operation is certified at the ISO 9001 level.

The Company generally purchases devices and componentsfrom more than one source where alternative sources areavailable; however, it does use sole source suppliers for cer-tain components. The Company believes that alternativecomponents for these sole source items could be incorpo-rated into the Company’s products, if necessary. While theCompany has been able to obtain adequate supplies of itscomponents from sole source suppliers, the future unavail-ability of components from these suppliers could disruptproduction and delivery of products until an alternativesource is identified. See also the Company’s Year 2000Readiness Disclosure Statement included in Management’sDiscussion and Analysis of Financial Condition and Resultsof Operations in Item 7 of this Report.

Product DevelopmentThe Company's research and development (“R&D”) staffincludes engineers and support persons who develop newproducts and provide engineering support for existing prod-ucts. The Company’s R&D efforts are also aimed at reduc-ing cost and total cycle time and improving product andcomponent quality. Most of these employees are located intwo Massachusetts facilities with additional resources

located in Denmark. Employees devoted to the improve-ment and development of software products are located inthe West Kingston, Rhode Island facility and in St. Louis,Missouri, at the Company’s subsidiary, SystemsEnhancement Corporation. The Company believes that thetechnical expertise of its R&D staff is very important to itsgrowth as technological change is rapid in the UPS field.

During 1998, the Company expanded its product offeringsin the enterprise market with the acquisition of Silcon, aleading manufacturer of three-phase UPSs up to 480 kVA.(For more information about this acquisition, see the“Acquisition” section included in Management’sDiscussion and Analysis of Financial Condition and Resultsof Operations in Item 7 of this Report.) Implementation ofAPC’s enterprise power protection strategy began in 1997with the introduction of the Symmetra Power Array, thefirst scalable and fault-tolerant power protection systemfor multiple servers, computer rooms, call centers, andback-office applications. The Company also innovated itsdesktop line of UPSs during 1998, revamping its Back-UPS® line and adding new features, including UniversalSerial Bus support, to select products in the Back-UPSPro® line. Additional areas of development included newproducts for the internetworking market; additional net-work management support via new PowerChute andPowerNet® solutions; and customized hardware and soft-ware products for strategic partners.

During 1997, the Company’s new product offeringsincluded the Symmetra Power Array, its first entry into theabove 5kVA market segment. Shipments of Symmetrabegan in the third quarter of 1997. The Company alsoadded additional products which strengthen theCompany’s position as an overall network solutionprovider. These introductions included additions to theCompany’s SurgeArrest line of surge protectors; addition-al and enhanced solutions for addressing manageabilityacross a growing number of operating systems and man-agement platforms; new rack-mount networking solutionsand special product development for our strategic part-ners and international marketplaces.

During 1996, the Company’s new product offerings includ-ed the Back-UPS Office® which was introduced in the sec-ond quarter. This product was designed to be solution spe-cific to the PC end-user, especially those using theInternet. Other new products included web managementcapability with PowerChute plus software, a network-man-ageable power distribution unit, and MasterSwitch, whichenables a network manager to control attached loadsindependent of each other.

Intellectual PropertyThe Company protects certain proprietary rights in its prod-ucts as well as certain proprietary technology develop-

ments by seeking patent protection. The Companybelieves that the loss of such rights concerning thesedevelopments would not have a material adverse effect onthe Company’s business. With respect to protection ofthose areas of its technology for which patent protectionhas not been sought, the Company relies on the complex-ity of its technology, trade secrecy law, and employee con-fidentiality agreements.

The Company has numerous trademarks registered in theUnited States and in many foreign countries. The Companyalso has trademark applications pending domestically andinternationally. The Company believes that its trademarksare valuable intangible assets, but also believes that theloss of any one trademark would not have a materialadverse effect on its operations.

CompetitionThe Company believes that it is one of less than ten globalcompanies providing a full range of UPS products and serv-ices worldwide. The Company’s principal competitorsinclude Exide Electronics Group, Inc., a business unit ofBTR PLC, Best Power, a business unit of SPX Corp., LiebertCorporation, a division of Emerson Electric Co., MGE UPSSystems, a privately held French company, Chloride Power,a subsidiary of Chloride Group PLC, and Phoenixtec PowerCompany Ltd., a publicly held Taiwanese company. TheCompany also competes with a number of other U.S. andnon-U.S. based companies which offer power protectionproducts similar to the Company’s products. Some of thesecompetitors have greater financial and other resources thanthe Company. The Company competes in the sale of itsproducts on the basis of several factors, including productperformance and quality, marketing and access to distribu-tion channels, customer service, product design, and price.

International OperationsThe Company plans to continue to expand its internationalmarketing efforts and manufacturing operations. With a fullline of internationally-positioned products already available,the Company continues to staff personnel to serve geo-graphical markets of interest. The Company’s primary man-ufacturing operations outside of the United States are locat-ed in Ireland, the Philippines, China, Denmark, andSwitzerland. For more information about the Company’srecent Denmark-based acquisition, see the “Acquisition”section included in Management’s Discussion and Analysisof Financial Condition and Results of Operations in Item 7 ofthis Report. The Company’s primary sales offices outside ofthe United States are located in Europe and the Far East.These offices, together with offices in other locations world-wide, provide sales and technical support to customersaround the globe. The Company utilizes third party ware-houses in Europe, the Far East, Canada, South Africa, andUruguay for distribution into its international markets.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Results of operationsThe following table sets forth the Company’s net sales, costof goods sold, gross profit, marketing, selling, general andadministrative expenses, R&D expenses, operating income,other income, earnings before income taxes and minorityinterest, earnings before minority interest, and net income,expressed as a percentage of net sales, for the years endedDecember 31, 1998, 1997, and 1996.

Revenues

Net sales in fiscal year 1998 increased by 28.9% to $1,125.8million from $873.4 million in fiscal year 1997, which reflect-ed a 23.6% increase from $706.9 million in fiscal year 1996.The increases from 1996 to 1998 are attributable to contin-ued strong demand for the Company's uninterruptiblepower supply products (“UPS”) and surge protection prod-ucts, combined with $49.8 million in 1998 net sales attrib-utable to Silcon (see “Acquisition” below). In addition, salesof new products and increased efforts by, and the additionof members to, the Company's sales staff have contributedto increased sales volumes. Net sales attributable to newproducts totaled approximately 11%, 8%, and 7%, of 1998,1997 and 1996 net sales, respectively.

Foreign sales to unaffiliated customers, primarily in Europe,the Far East, Canada, and South America, were $486.6 mil-lion or 43.2% of net sales in fiscal year 1998 compared to$378.3 million or 43.3% of net sales in fiscal year 1997 and$305.1 million or 43.2% of net sales in fiscal year 1996. Seealso note 8 to the consolidated financial statements.

Cost of Goods Sold

Cost of goods sold was $621.1 million or 55.2% of net salesin fiscal year 1998 compared to $476.1 million or 54.5% ofnet sales in fiscal year 1997. Gross margins declined byapproximately 70 basis points during 1998 from fiscal year1997. Substantially all of the gross margin erosion was prod-uct mix related as the Company’s high-power UPS businessnow accounts for a larger percentage of revenue.

Cost of goods sold was $476.1 million or 54.5% of net salesin fiscal year 1997 compared to $407.9 million or 57.7% ofnet sales in fiscal year 1996. Gross margins improved byapproximately 320 basis points during 1997 over fiscal year1996, primarily attributable to several factors including, butnot limited to: continued improvement in margins on lowercost Back-UPS products manufactured in the Philippines,the favorable margin impact of a higher-end product mixresulting from strong growth in Smart-UPS sales into theserver segment of the power protection market, and vol-ume production efficiencies, partially offset by certain pricereductions implemented during the fourth quarter.

Total inventory reserves at December 31, 1998 were $13.3million compared to $19.3 million at December 31, 1997.The Company’s reserve estimate methodology involvesquantifying the total inventory position having potential lossexposure, reduced by an amount reasonably forecasted tobe sold, and adjusting its interim reserve provisioning tocover the net loss exposure.

Operating Expenses

Marketing, selling, general, and administrative (SG&A)expenses were $260.2 million or 23.1% of net sales in 1998compared to $203.5 million or 23.3% of net sales in 1997 and$150.4 million or 21.3% of net sales in 1996. The increases intotal spending in 1998 and 1997 were due primarily to costsassociated with increased staffing and operating expenses ofselling, administrative, and marketing functions, as well asincreased advertising and promotional costs.

The allowance for bad debts was 7.9% of accounts receivableat December 31, 1998 compared to 8.5% at December 31,1997. The Company continues to experience strong collectionperformance from its accounts receivable with outstandingbalances over 60 days outstanding representing 8.6% and6.6% of total receivables at December 31, 1998 and 1997,respectively. Write-offs of uncollectible accounts representless than 1% of net sales. A majority of international customerbalances are covered by receivables insurance.

R&D expenditures for 1998, 1997 and 1996 were $32.6 mil-lion, $22.4 million, and $14.8 million, respectively. Theincreased R&D spending primarily reflects increased num-bers of software and hardware engineers and costs associ-ated with new product development and engineering sup-port. In addition, during 1998, the Company recorded non-recurring charges of $7.6 million for acquired in-processR&D in connection with its acquisition of Silcon (see“Acquisition” below). The Company expects its recurringR&D expenditures to remain at substantially the same levelas a percentage of sales for the foreseeable future.

Other Income, Net and Income Taxes

Other income is comprised principally of interest income,which increased substantially from 1996 to 1998 due tohigher average cash balances available for investment dur-ing 1997 and 1998.

Excluding 1998 non-tax deductible charges of $7.6 millionfor acquired in-process R&D (see “Acquisition” below), theCompany's effective income tax rates were 30.5%, 31.5%,and 33.5% in 1998, 1997 and 1996, respectively. Thedecrease from 1996 to 1998 is due to the expected tax sav-ings from an increasing portion of taxable earnings beinggenerated from the Company’s operations in Ireland, a juris-diction which currently has a lower income tax rate for man-ufacturing companies than the present U.S. statutoryincome tax rate.

Effects of InflationManagement believes that inflation has not had a materialeffect on the Company’s operations.

Liquidity and Financial ResourcesWorking capital at December 31, 1998 was $493.8 millioncompared to $426.8 million at December 31, 1997. TheCompany’s cash position decreased to $219.9 million atDecember 31, 1998 from $270.1 million at December 31,1997, primarily due to the cash purchase of approximately89% of the share capital of Silcon (see “Acquisition”below).

Worldwide inventories were $228.7 million at December 31,1998 compared to $104.2 million at December 31, 1997.Inventories increased during 1998 due to increased demandand increased sourcing from the Philippines where longertransit times result in higher finished goods inventories,combined with $19 million of inventory purchased in theSilcon acquisition.

At December 31, 1998, the Company had $50 million avail-able for future borrowings under an unsecured line of cred-it agreement at a floating interest rate equal to the bank’scost of funds rate plus .625% and an additional $15 millionunder an unsecured line of credit agreement with a secondbank at a similar interest rate. No borrowings were out-standing under these facilities at December 31, 1998. Inconnection with the acquisition of Silcon (see “Acquisition”below), the Company acquired $24.8 million in bank indebt-edness with interest rates ranging from 4% to 8%. TheCompany repaid $12.3 million of this indebtedness duringthe second half of 1998. The Company had no significantfinancial commitments, other than those required in thenormal course of business, at December 31, 1998.

During 1998 and 1997, the Company's capital expenditures,net of capital grants, amounted to approximately $55.7 mil-lion and $37.2 million, respectively, consisting primarily ofmanufacturing and office equipment, buildings andimprovements, and purchased software applications. The

nature and level of capital spending was made to improvemanufacturing capabilities, establish additional manufactur-ing capabilities in China, the Philippines, and Ireland to sup-port the increased selling, marketing, and administrativeefforts necessitated by the Company's significant growth,and to improve the Company’s enterprise-wide softwareapplications. Substantially all of the Company’s net capitalexpenditures were financed from available operating cash.The Company had no material capital commitments atDecember 31, 1998. Capital expenditures in 1999 areplanned to grow in line with expected 1999 revenuegrowth, primarily to support planned capacity expansions.

The Company has agreements with the IndustrialDevelopment Authority of Ireland (“IDA”) under which theCompany receives grant monies for costs incurred formachinery, equipment, and building improvements for itsGalway and Castlebar facilities equal to 40% and 60%,respectively, of such costs up to a maximum of $13.1 mil-lion and $1.3 million, respectively. Such grant monies aresubject to the Company meeting certain employment goalsand maintaining operations in Ireland until termination of therespective agreements. Under separate agreements withthe IDA, the Company receives direct reimbursement oftraining costs at its Galway and Castlebar facilities for up to$3,000 and $12,500, respectively, per new employee hired.See also note 12 to the consolidated financial statements.

During the fourth quarter of 1998, the Company beganestablishing a manufacturing operation in India. TheCompany will be leasing a 42,000 square foot facility inBangalore and expects to begin manufacturing selectedproducts at this facility during the second quarter of 1999.

During the first quarter of 1998, the Company established amanufacturing operation in China. The Company is leasing a50,000 square foot facility in Suzhou and began manufac-turing selected products at this facility during the third quar-ter of 1998. Capital expenditures for the China expansionwere financed from operating cash.

The Company’s manufacturing operation in the Philippinesis operating within a designated economic zone which pro-vides certain economic incentives, primarily in the form oftax exemptions. In August 1998, the Company purchased athird manufacturing facility in the Philippines for approxi-mately $750,000, financed from operating cash. ThePhilippines facilities currently manufacture certain Back-UPS and Smart-UPS products sold in the Company’sdomestic and international markets.

The Company continues to evaluate international manufac-turing expansion, including additional locations in the FarEast and South America.

Management believes that current internal cash flowstogether with available cash, available credit facilities or, ifneeded, the proceeds from the sale of additional equity, willbe sufficient to support anticipated capital spending and otherworking capital requirements for the foreseeable future.

Acquisition of Silcon A/SEarly in the second quarter of 1998, the Company enteredinto a definitive agreement with the principal managementshareholders of Silcon A/S (“Silcon”) to acquire stock ofSilcon, a Denmark-based manufacturer of three-phase UPSsup to 480 kilo volt-amps (“kVA”), and the Company com-menced a tender offer for Silcon shares. In June 1998, theinitial tender offer and purchase of stock from principal man-agement shareholders was completed enabling theCompany to operate Silcon as a majority-owned subsidiary.During the second half of 1998, the Company increased itsownership percentage to 89%. The Company’s 1998 cashoutlays associated with the acquisition aggregating $64 mil-lion were financed from operating cash. In January 1999, theCompany attained ownership of more than 90% of the sharecapital of Silcon through open market purchases financedfrom operating cash and commenced a mandatory redemp-tion of the remaining Silcon shares. Through this mandatoryshare redemption process, the Company anticipates that itwill complete its acquisition of the remaining outstandingshares of Silcon during the second half of 1999. In connec-tion with the mandatory redemption, the Copenhagen StockExchange has approved the de-listing of Silcon’s shareseffective March 1, 1999.

The purchase price was allocated to the net tangible and iden-tifiable intangible assets acquired and to acquired in-processR&D (“acquired R&D”). Acquired R&D includes the value ofproducts in the development stage that are not considered tohave reached technological feasibility and that have no alter-native future uses. The acquired R&D effort related to sever-al technologies for products that Silcon was developing forwhich the Company intends to complete development. At thevaluation date, none of these products had demonstratedtheir technological or commercial feasibility. Significant riskexists since the Company is unable to predict with certaintythe obstacles it may encounter in the form of time and costnecessary to produce technologically feasible products.Should these proposed products fail to become viable, the in-process technology has no alternative use and it is unlikelythat the Company would be able to realize any value from thesale of the technology to another party. The Company usedprofessional consultants to assess and allocate values to theacquired R&D, which were determined by estimating the con-tribution of the acquired R&D technology to developing com-mercially viable products, estimating the resulting net cashflows from the expected sales of such products, and dis-counting the net cash flows to their present value using a risk-adjusted discount rate. The Company believes that theassumptions used in the forecasts were reasonable at thetime of the acquisition. No assurance can be given, however,that the underlying assumptions used to estimate expectedproduct sales, development costs, or profitability will transpireas estimated. For these reasons, actual results may vary fromthe projected results.

In accordance with applicable accounting rules, acquired R&Dis required to be expensed. Accordingly, $7.6 million of theacquisition cost was expensed in 1998. The remaining pur-

chase price exceeded the fair value of the tangible net assetsacquired by approximately $47 million, consisting of identifi-able intangible assets and goodwill, which is being amortizedon a straight-line basis over 15 years. The acquisition hasbeen accounted for as a purchase and, accordingly, Silcon’sresults of operations are included in the Company’s consoli-dated financial statements from the date of acquisition.

Foreign Currency ActivityThe Company invoices its customers in Denmark, France,Germany, Great Britain, Switzerland, and Japan in their respec-tive local currencies. Realized and unrealized transaction gainsor losses are included in the results of operations and aremeasured based upon the effect of changes in exchange rateson the actual or expected amount of functional currency cashflows. Transaction gains and losses were not material to theresults of operations in 1998, 1997 and 1996.

At December 31, 1998, the Company’s unhedged foreigncurrency accounts receivable, by currency, were as follows:

The Company also had non-trade receivables of 3.9 millionIrish Pounds (approximately US$5.8 million), as well as IrishPound denominated liabilities of 3.9 million (approximatelyUS$5.8 million). The Company also had short term debt andliabilities denominated in various European currencies ofUS$42.8 million, as well as Yen denominated liabilities ofapproximately US$1.6 million.

The Company continually reviews its foreign exchange expo-sure and considers various risk management techniques,including the netting of foreign currency receipts and dis-bursements, rate protection agreements with customers/ven-dors and derivatives arrangements, including foreignexchange contracts. The Company presently does not utilizerate protection agreements or derivative arrangements.

Recently Issued Accounting StandardThe Financial Accounting Standards Board recently issuedStatement of Financial Accounting Standards (“SFAS”)No. 133, Accounting for Derivative Instruments andHedging Activities, which establishes accounting andreporting standards for derivative instruments, includingcertain derivative instruments embedded in other con-tracts (collectively referred to as derivatives), and forhedging activities. This Statement is effective for all fiscalquarters of fiscal years beginning after June 15, 1999. Theadoption of this Statement is not expected to have a

The AICPA Accounting Standards Executive Committeerecently issued Statement of Position (“SOP”) 98-1,Accounting for the Costs of Computer Software Developedor Obtained for Internal Use. This SOP requires that certaincosts related to the development or purchase of internal-use software be capitalized and amortized over the esti-mated useful life of the software, and is effective for fiscalyears beginning after December 15, 1998. The SOP alsorequires that costs related to the preliminary project stageand post implementation/operations stage in an internal-usecomputer software development project be expensed asincurred. The adoption of this SOP is not expected to havea material impact on the Company’s consolidated financialposition or results of operations.

The AICPA Accounting Standards Executive Committeerecently issued SOP 98-5, Reporting on the Costs of Start-Up Activities. This SOP requires that costs incurred duringstart-up activities, including organization costs, be expensedas incurred, and is effective for fiscal years beginning afterDecember 15, 1998. The adoption of this SOP is expectedto have no impact on the Company’s consolidated financialposition or results of operations.

Year 2000 Readiness Disclosure StatementMany computer systems were not designed to handle anydates beyond the year 1999 and, therefore, many compa-nies will be required to modify their computer hardware andsoftware prior to the year 2000 in order to remain fully oper-ational. During 1998, the Company commenced a year 2000readiness program to assess the impact of the year 2000issue on the Company’s operations and address necessaryremediation. A year 2000 program director reporting direct-ly to senior management has been assigned to this project.

Assessment of the Company’s Products for Year 2000 Compliance

All of the Company’s hardware products and accessoriesare year 2000 compliant, meaning that they have been test-ed to verify that where date fields are processed, dates arecalculated and displayed accurately, and that scheduledevents such as shutdowns, self-tests, and run-time calibra-tions, and also the handling of unscheduled events, such aspower failures, are unaffected by the millennium and cen-tury change; provided that all other third party products(e.g., software, firmware, operating systems, and hard-ware) properly exchange date data with the Company’sproducts and provided also that the Company’s products areused in accordance with the product documentation. Inaddition, the Company’s year 2000 compliant products rec-ognize the year 2000 as a leap year. The Company has alsotested its software products and determined that theseproducts are substantially year 2000 compliant, and theCompany intends to resolve any remaining year 2000issues before the beginning of the fourth quarter of 1999.

Periodically updated information about the Company’s soft-ware products is available at the Company’s Year 2000Readiness Disclosure Web site (www.apcc.com).Information on this site is provided to the Company’s cus-tomers for the sole purpose of assisting in planning for tran-sition to the year 2000. Such information is the most cur-rently available concerning the behavior of the Company’sproducts in the next century and is provided “as is” withoutwarranty of any kind. In addition, to the extent theCompany’s hardware and software products are combinedwith the hardware and software products of other compa-nies, there can be no assurance that users of theCompany’s products will not experience year 2000 prob-lems as a result of the combination of the Company’s hard-ware and software products with non-compliant products ofother companies. The Company currently does not antici-pate material expenditures to remedy any year 2000 issueswith its products and services.

Assessment of the Company’s Information Technology (“IT”)and Non-IT Systems for Year 2000 Compliance

The Company is currently in the process of evaluating its ITsystems for compliance. The Company’s Oracle manufac-turing and financial information systems were implementedduring 1998. The Company is evaluating the year 2000 com-pliance of these systems in accordance with Oracle’s rec-ommendations. At December 31, 1998, the Company hadcompleted its initial installation and testing of softwarepatches available from Oracle. The Company is currentlycontinuing to install and test additional software patches asthey become available from Oracle. The Company does notconsider the cost of the new hardware and software for theOracle implementations to be related to year 2000 readi-ness as these system replacements were already plannedto satisfy the demands of expansion of its worldwide oper-ations and were not accelerated due to year 2000 issues.The Company is also currently in the process of evaluatingits non-IT systems for compliance. Additionally, theCompany utilizes other third party software and equipmentto distribute its products as well as to operate other aspectsof its business. The Company is reviewing such softwareand equipment. The Company’s review process is expectedto be completed before the beginning of the fourth quarterof 1999. There can be no assurance that such software andequipment is year 2000 compliant, that non-compliant soft-ware and equipment will be made compliant on a timelybasis, or that any such non-compliant software and equip-ment would not have a material adverse effect on theCompany’s systems and operations.

Evaluation of Third Parties with which the Company has aMaterial Relationship, including Key Suppliers, ServiceProviders, and Strategic Partners

The Company’s year 2000 readiness program includesidentifying these third parties and determining, based onreceipt of written verification, review of publicly availablefinancial statement disclosures, and other means, thatsuch third parties are either in compliance or expect to be

in compliance prior to January 1, 2000. The Company iscurrently in the process of communicating with its signif-icant vendors, service providers, and certain strategicpartners. Many enterprises, including the Company’spresent and potential customers, may be devoting a sub-stantial portion of their information systems spending toresolving year 2000 issues, which may result in theirspending being diverted from applications such as theCompany’s products, over the next two years.

Development of Contingency Plans

The Company is currently not in a position to determine whatwould be its most reasonably likely worst case year 2000scenario or any plan for handling such scenario. To date, theCompany has not completed a formal contingency plan fornon-compliance, however to the extent that further evalua-tion of its products, its IT and non-IT systems, or informationobtained from the third parties with which it has a materialrelationship suggests that there is a significant risk, contin-gency plans will be implemented. Such contingency plansmay include the development of alternative sources for theproduct or service provided by any non-compliant vendor.

It is the Company’s policy to expense as incurred all costsassociated with year 2000 readiness. The Company hasdeveloped a separate budget for operating and capitalexpenditures relating to year 2000 issues. No IT projectshave been deferred due to year 2000 efforts. Although theCompany is not yet able to estimate its total incrementalcost for year 2000 issues, based on its preliminary review todate, the Company does not believe that the costs of year2000 issues will have a material adverse effect on theCompany’s business, operating results, or financial condi-tion. Although the Company is taking measures to addressthe impact, if any, of year 2000 issues, it cannot predict theoutcome or success of its year 2000 readiness program, orwhether the failure of third party systems or equipment tooperate properly in the year 2000 will have a materialadverse effect upon the Company’s business, operatingresults, or financial condition, or require the Company toincur unanticipated material expenses to remedy any year2000 issue.

The foregoing discussion regarding the Company’s year2000 readiness program’s implementation, effectiveness,and cost, contains forward-looking statements which arebased on management’s expectations, determined utilizingcertain assumptions of future events, including third partycompliance and other factors. However, there can be noguarantee that these expectations will be realized, and actu-al results could differ materially from management’s expec-tations. Specific factors that might cause such material dif-ferences include, but are not limited to, the availability andcost of personnel trained in this area and other similar uncer-tainties, and the remediation success of the Company’s sup-pliers, service providers, and strategic partners.

Factors That May Affect Future ResultsThis document may include forward-looking statements.Any statements contained herein that do not describe his-torical facts are forward-looking statements. The Companymakes such forward-looking statements under the provi-sions of the “safe harbor” section of the Private SecuritiesLitigation Reform Act of 1995. The forward-looking state-ments contained herein are based on current expectations,but are subject to a number of risks and uncertainties. Thefactors that could cause actual results to differ materiallyfrom such forward-looking statements include the risk fac-tors set forth below.

Fluctuations in Revenue and Operating Results

The Company’s quarterly operating results may fluctuate asa result of a number of factors, including the growth rates inthe UPS industry and related industries; timing of ordersfrom, and shipments to, customers; the timing of new prod-uct introductions and the market acceptance of those prod-ucts; increased competition; changes in manufacturingcosts; changes in the mix of product sales; inventory risksdue to shifts in market demand; component constraints andshortages; risks of nonpayment of accounts receivable;expansion of manufacturing capacity; factors associatedwith international operations; and changes in world eco-nomic conditions.

Management of Growth

The Company has experienced, and is currently experi-encing, a period of rapid growth which has placed, andcould continue to place, a significant strain on theresources of the Company. In order to support thegrowth of its business, the Company plans to signifi-cantly expand its level of operations during 1999. If theCompany’s management is unable to manage growtheffectively, the Company’s operating results could beadversely affected.

Competition

The Company believes that it is one of less than ten globalcompanies providing a full range of UPS products and serv-ices worldwide. The UPS industry, however, is highly com-petitive on both a worldwide basis and a regional geograph-ic basis. The Company competes, and will continue to com-pete, with several U.S. and foreign firms with respect toUPS products, both on a worldwide basis and in variousgeographical regions, and within individual UPS product andapplication niches. The Company expects competition toincrease in the future from existing competitors and a num-ber of companies which may enter the Company’s existingor future markets. Increased competition could adverselyaffect the Company’s revenue and profitability through pricereductions and loss of market share. The principal competi-tive factors in the UPS industry are product performanceand quality, marketing and access to distribution channels,

customer services, product design and price. Some of theCompany’s current and potential competitors have substan-tially greater financial, technical, sales and marketingresources than the Company. There can be no assurancethat the Company will be able to continue to compete suc-cessfully with its existing competitors or will be able tocompete successfully with new competitors.

Technological Change; New Product Delays; Risks ofProduct Defects

The market for the Company’s products is characterized byrapidly changing technology, evolving industry standards andfrequent new product introductions. Current competitors ornew market entrants may develop new products with fea-tures that could adversely affect the competitive position ofthe Company’s products. There can be no assurance that theCompany will be successful in selecting, developing, manu-facturing and marketing new products or enhancing its exist-ing products or that the Company will be able to respondeffectively to technological changes, new standards or prod-uct announcements by competitors. The timely availability ofnew products and enhancements, and their acceptance bycustomers are important to the future success of theCompany. Delays in such availability or a lack of marketacceptance could have an adverse effect on the Company.Although the Company has not experienced materialadverse effects resulting from product defects, there can beno assurance that, despite testing internally or by current orpotential customers, defects will not be found in products,resulting in loss or delay in market acceptance, which couldhave a material adverse effect upon the Company’s busi-ness, operating results, or financial condition.

Year 2000 Issues

Although the Company is taking measures to address theimpact, if any, of year 2000 issues, it cannot predict the out-come or success of its year 2000 readiness program, orwhether the failure of third party systems or equipment tooperate properly in the year 2000 will have a materialadverse effect upon the Company’s business, operatingresults, or financial condition, or require the Company toincur unanticipated material expenses to remedy any year2000 issue. See also the Company’s Year 2000 ReadinessDisclosure Statement above.

Dependence on Key Employees

The Company’s success depends to a significant degreeupon the continuing contributions of its key management,sales, marketing, R&D and manufacturing personnel, manyof whom would be difficult to replace. The Company doesnot have employment contracts with most of its key per-sonnel. The Company believes that its future success willdepend in large part upon its ability to attract and retain high-ly-skilled hardware and software engineers, and manage-ment, sales and marketing personnel. Competition for suchpersonnel is intense, and there can be no assurance that theCompany will be successful in attracting and retaining such

personnel. Failure to attract and retain key personnel couldhave a material adverse effect on the Company’s business,operating results, or financial condition.

Foreign Operations; Risk of Currency Fluctuations

The Company manufactures and markets its productsworldwide through several foreign subsidiaries and inde-pendent agents. The Company’s worldwide operations aresubject to the risks normally associated with foreign opera-tions including, but not limited to, the disruption of markets,changes in export or import laws, restrictions on currencyexchanges, potentially negative tax consequences and themodification or introduction of other governmental policieswith potentially adverse effects.

International sales (sales to customers outside the UnitedStates, both direct and indirect) accounted for approxi-mately 43.2%, 43.3%, and 43.2% of the Company’s netsales in 1998, 1997, and 1996, respectively. TheCompany anticipates that international sales will continueto account for a significant portion of revenue. TheCompany invoices its customers in Denmark, France,Germany, Great Britain, Switzerland, and Japan in theirrespective local currencies. To date, the Company doesnot utilize any rate protection agreements or derivativeagreements to hedge any foreign exchange exposure.Accordingly, the Company may be exposed to exchangelosses based upon currency exchange rate fluctuations,which losses could have a materially adverse effect onthe Company’s operating results.

Dependence on Sole Source Suppliers

Some components of the Company’s products are current-ly obtained from single sources. There can be no assurancethat in the future the Company’s suppliers will be able tomeet the Company’s demand for components in a timelyand cost-effective manner. The Company generally pur-chases these single or limited source components pursuantto purchase orders and has no guaranteed supply arrange-ments with the suppliers. In addition, the availability ofmany of these components to the Company is dependentin part on the ability of the Company to provide the suppli-ers with accurate forecasts of future requirements. TheCompany has generally been able to obtain adequate sup-plies of parts and components in a timely manner fromexisting sources. The Company’s operating results and cus-tomer relationships could be adversely affected by either anincrease in prices for, or an interruption or reduction in sup-ply of, any key components.

Uncertainties Regarding Patents and Protection ofProprietary Technology

The Company’s success will depend, to a large extent, onits ability to protect its proprietary technology. The Companyrelies on a combination of contractual rights, trade secretsand copyrights to protect its proprietary rights. Although theCompany may apply for patents in the future, there can beno assurance that the Company’s intellectual property pro-

37

Managem

ent’s Discussion and A

nalysis

tection will be sufficient to prevent competitors from devel-oping similar technology. Moreover, in the absence ofpatent protection, the Company’s business may be adverse-ly affected by competitors that independently develop func-tionally equivalent technology. The Company attempts toensure that its products and processes do not infringe uponpatents and other proprietary rights, but there can be noassurance that such infringement may not be alleged bythird parties in the future. If infringement is alleged or deter-mined, there can be no assurance that the necessary licens-es would be available on acceptable terms, if at all, or thatthe Company would prevail in any such challenge.

Integration of Acquired Businesses

The Company has limited experience in integrating acquiredcompanies or technologies into its operations. TheCompany may from time to time pursue the acquisition ofother companies, assets, products or technologies. Therecan be no assurance that products, technologies, distribu-tion channels, key personnel and businesses of acquiredcompanies will be successfully integrated into theCompany’s business or product offerings, or that such inte-gration will not adversely affect the Company’s business,operating results, or financial condition. There can be noassurance that any acquired companies, assets, products ortechnologies will contribute significantly to the Company’ssales or earnings, or that the sales and earnings fromacquired businesses will not be adversely affected by theintegration process or other factors. If the Company is notsuccessful in the integration of such acquired businesses,there could be an adverse impact on the financial results ofthe Company. There can be no assurance that the Companywill continue to be able to identify and consummate suitableacquisition transactions in the future. For information on theCompany’s recent acquisition of Silcon, see the“Acquisition” section above. The Company’s determinationof acquired R&D in connection with this acquisition is sub-ject to review and revaluation by the Securities andExchange Commission.

Possible Volatility of Stock Price

The market price of the Company’s Common Stock hasbeen, and may continue to be, extremely volatile. The trad-ing price of the Company’s Common Stock could be subjectto wide fluctuations in response to quarter-to-quarter varia-tions in operating results, changes in earnings estimates byanalysts, announcements of technological innovations or

new products by the Company or its competitors, chal-lenges associated with integration of businesses and otherevents or factors. In addition, the stock market has fromtime to time experienced extreme price and volume fluctu-ations which have particularly affected the market price formany high technology companies and which often havebeen unrelated to the operating performance of these com-panies. These broad market fluctuations may adverselyaffect the market price of the Company’s Common Stock.

Tax Rate

The Company’s tax rate is heavily dependent upon theproportion of earnings that are derived from its Irelandand Philippines manufacturing operations and its ability toreinvest those earnings permanently outside the UnitedStates. If the earnings of these operations as a percent-age of the Company’s total earnings were to decline sig-nificantly from anticipated levels, or should its ability toreinvest these earnings be reduced, the Company’s effec-tive tax rate would exceed the currently estimated rate for1999. In addition, should the Company’s intercompanytransfer pricing with respect to its Ireland or Philippinesmanufacturing operations require significant adjustmentdue to audits or regulatory changes, the Company’s over-all effective tax rate could increase.

Uncertainty Regarding the Litigation Process

The Company has been, is, and/or may in the futurebecome involved in material litigation involving theCompany, its products or its operations. The litigationprocess is uncertain and includes the risk of an unexpected,unfavorable result and there can be no assurance that theCompany will not be materially adversely impacted by anysuch litigation.

Item 7A. Quantitative and QualitativeDisclosures About Market Risk

The Company, in the normal course of business, is exposedto market risks relating to fluctuations in foreign currencyexchange rates. The information required under this sectionrelated to such risks is included in the Foreign CurrencyActivity section of Management’s Discussion and Analysis ofFinancial Condition and Results of Operations in Item 7 of thisReport and is incorporated herein by reference.

AMERICAN POWER CONVERSION CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Years ended December 31, 1998, 1997 and 1996

1. Summary of Significant Accounting Policies

Nature of Business

American Power Conversion Corporation and its sub-sidiaries (the “Company”) designs, develops, manufac-tures, and markets power protection and managementsolutions for computer and electronic applications world-wide. The Company’s solutions include uninterruptiblepower supply products (“UPS”), electrical surge protectiondevices, power conditioning products, associated software,services, and accessories. These solutions are for use withsensitive electronic devices which rely on electric utilitypower including, but not limited to, home electronics, per-sonal computers (“PCs”), high performance workstations,servers, networking equipment, telecommunications equip-ment, internetworking equipment, datacenters, mainframecomputers, and facilities. The Company’s principal marketsare in North America, Europe, and the Far East.

Principles of Consolidation

The consolidated financial statements include the accountsof American Power Conversion Corporation and all of itswholly- and majority-owned subsidiaries. All intercompanyaccounts and transactions are eliminated in consolidation.

Cash and Cash Equivalents

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

Inventories

Inventories are stated at the lower of cost or market, costbeing 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 methodover 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 and other intangibles represents the excess ofcost over the fair value of the net tangible assets of busi-nesses acquired and is being amortized on a straight-linebasis over 15 years. Periodically, the Company evaluatesthe recovery of goodwill to assure that changes in facts andcircumstances do not suggest that recoverability has beenimpaired. This analysis relies on a number of factors, includ-ing operating results, business plans, budgets, economicprojections, and changes in management’s strategic direc-tion or market emphasis. In management’s opinion, noimpairment exists at December 31, 1998.

Research and Development

Expenditures for R&D are expensed in the year incurred.

Warranties

The Company offers limited two-year and one-year war-ranties. The provision for potential liabilities resulting fromwarranty claims is provided at the time of sale. The provi-sion is computed based upon historical data and currentestimates. The Company also offers its customers theopportunity to extend the basic warranty period up to anadditional three years under a separately priced program.Recognition of the revenue associated with the extendedwarranty program commences on the date the extendedwarranty becomes effective and is recognized on a straight-line basis over the extended warranty period. In addition,the Company has an Equipment Protection Policy whichprovides up to $25,000 for repair or replacement of a cus-tomers’ hardware should a surge or lightning strike passthrough a Company unit. The policy applies to all units man-ufactured after January 1, 1992. Other restrictions alsoapply. The Company’s ProtectNet line of data line surgesuppressors feature a unique “Double-Up” SupplementalEquipment Protection Policy, under which the total recover-able limit under the Equipment Protection Policy is dou-bled, up to $50,000 (U.S. and Canada only). The Companyhas experienced satisfactory field operating results, andwarranty costs incurred to date have not had a significantimpact on the Company’s results of operations.

Income Taxes

Income taxes are accounted for under the asset and liabilitymethod. Under this method, deferred tax assets and liabili-ties are recognized for the future tax consequences attribut-able to differences between the financial statement carryingamounts of existing assets and liabilities and their respectivetax bases. Deferred tax assets and liabilities are measuredusing enacted tax rates expected to apply to taxable incomein the years in which those temporary differences areexpected to be recovered or settled. The effect on deferredtax assets and liabilities of a change in tax rates is recognizedin income in the period that includes the enactment date.

Deferred income taxes have not been provided for theundistributed earnings of the Company’s foreign sub-

44

ents

sidiaries which aggregated approximately $180 million atDecember 31, 1998. The Company plans to reinvest allsuch earnings for future expansion. If such earnings weredistributed, taxes would be increased by approximately$48 million.

Earnings per Share

Basic earnings per share is computed by dividing netincome by the weighted average number of commonshares outstanding during the period. Diluted earnings pershare is computed by dividing net income by the weightedaverage number of common shares and dilutive potentialcommon shares outstanding during the period. Under thetreasury stock method, the unexercised options areassumed to be exercised at the beginning of the period orat issuance, if later. The assumed proceeds are then usedto purchase common shares at the average market priceduring the period.

Potential common shares for which inclusion would havethe effect of increasing diluted earnings per share (i.e.,antidilutive) are excluded from the computation. Antidilutivepotential common shares outstanding at December 31,1998, 1997, and 1996 were approximately 248,000,83,000, and 68,000, respectively.

Stock-Based Compensation

The Company applies APB Opinion 25 and relatedInterpretations in accounting for its stock option plans. Nocompensation cost has been recognized for these plans inthe accompanying consolidated financial statements.

Advertising Costs

Advertising costs are expensed as incurred and reportedin selling, general, and administrative expenses in theaccompanying consolidated statements of income. Suchcosts of advertising, advertising production, trade shows,and other activities designed to enhance demand for theCompany’s products. Advertising costs were $67.4 millionin 1998, $59.9 million in 1997, and $36.3 million in 1996.There are no capitalized advertising costs in the accompa-nying consolidated balance sheets.

Use of Estimates

The preparation of financial statements in conformity withgenerally accepted accounting principles requires manage-ment to make estimates and assumptions that affect thereported amounts of assets and liabilities and disclosure ofcontingent assets and liabilities at the date of the financialstatements and the reported amounts of revenues andexpenses during the reporting period. Actual results maydiffer from those estimates.

2. Accounts ReceivableAccounts receivable are generally not concentrated in anygeographic region or industry. Collateral is usually notrequired except for certain international transactions forwhich the Company requires letters of credit to secure pay-ment. The Company estimates an allowance for doubtfulaccounts based on the credit worthiness of its customersas well as general economic conditions. Consequently, anadverse change in those factors could affect theCompany’s estimate of its bad debts.

3. InventoriesInventories consist of the following:

4. Revolving Credit Agreements and Short Term DebtAt December 31, 1998, the Company had available forfuture borrowings $50 million under an unsecured line ofcredit agreement at a floating interest rate equal to thebank’s cost of funds rate plus .625% and an additional $15million under an unsecured line of credit agreement with asecond bank at a similar interest rate. No borrowings wereoutstanding under these facilities at December 31, 1998. Inconnection with the acquisition of Silcon, the Companyacquired $24.8 million in bank indebtedness with interestrates ranging from 4% to 8%. The Company repaid $12.3million of this indebtedness during the second half of 1998.

In assessing the realizability of deferred tax assets, theCompany considers whether it is more likely than not thatsome portion or all of the deferred tax assets will not be real-ized. Due to the fact that the Company has sufficient taxableincome in the federal carryback period and anticipates suffi-cient future taxable income over the periods which thedeferred tax assets are deductible, the ultimate realization ofdeferred tax assets for federal and state tax purposes appearsmore likely than not. The U.S. federal taxable income for1997, 1996 and 1995 was approximately $111.6 million, $98.3million, and $82.8 million, respectively.

6. Stock Plans

Stock Option Plans

At December 31, 1998, the Company had four stock optionplans, which are described below. SFAS No. 123, Accountingfor Stock-Based Compensation, requires companies to either(a) record an expense related to its stock option plans basedon the estimated fair value of stock options as of the date ofthe grant or (b) disclose pro forma net income and earningsper share data as if the company had recorded an expense,beginning with options granted in 1995. The Company haselected to continue to apply APB Opinion 25 and relatedInterpretations in accounting for these plans and to complywith the SFAS No. 123 disclosure requirements. Accordingly,no compensation cost has been recognized for its stockoption plans in the accompanying consolidated financialstatements. Had compensation cost for such plans beendetermined based on the fair value at the grant dates forawards under these plans consistent with the method ofSFAS No. 123, the Company’s net income and earnings pershare would have been reduced to the pro forma amountsindicated below:

The pro forma effect on net income for 1998, 1997 and 1996is not representative of the pro forma effect on net income infuture years because it does not take into consideration proforma compensation expense related to grants made prior to1995. The weighted average fair value of options granted dur-ing 1998, 1997 and 1996 was $17.67, $11.19, and $5.13,respectively. The Company estimates the fair value of eachoption as of the date of grant using the Black-Scholes pricingmodel with the following weighted average assumptionsused for grants in 1998, 1997 and 1996:

On April 21, 1997, the Company’s shareholders approved the1997 Stock Option Plan and on June 19, 1987 approved the1987 Stock Option Plan (collectively the “Plans”). The 1997and 1987 Stock Option Plans authorized the grant of optionsfor up to 6.0 million shares and 10.8 million shares, respec-tively, of common stock. Options granted under the Plans areeither (a) options intended to constitute incentive stockoptions (“ISOs”) under the Internal Revenue Code of 1986(the “Code”) or (b) non-qualified options. Incentive stockoptions may be granted under the Plans to employees or offi-cers of the Company. Non-qualified options may be grantedto consultants, directors (whether or not they are employ-ees), employees or officers of the Company.

ISOs granted under the Plans may not be granted at a priceless than the fair market value of the common stock on thedate of grant (or 110% of fair market value in the case ofemployees or officers holding 10% or more of the votingstock of the Company). The aggregate fair market value ofshares, for which ISOs granted to any employee are exer-cisable for the first time by such employee during any cal-endar year (under all stock option plans of the Company andany related corporation), may not exceed $100,000. Non-qualified options granted under the Plan may not be grantedat a price less than the lesser of (a) the book value per shareof common stock as of the end of the fiscal year of theCompany immediately preceding the date of such grant, or(b) 50% of the fair market value of the common stock on thedate of grant.

Options granted under the Plans before December 1, 1995vested 25% at the end of the first year and 12.5% at the endof each six month period thereafter. Options granted afterDecember 1, 1995 and before February 14, 1997 vest 20% atthe end of the second year and 20% at the end of each yearthereafter. Options granted after February 14, 1997 vest 25%at the end of the first year and 12.5% at the end of each sixmonth period thereafter.

On April 21, 1997, the Company’s shareholders approved the1997 Non-employee Director Stock Option Plan and on May20, 1993 approved the 1993 Non-employee Director StockOption Plan (collectively the “Director Plans”). Optionsgranted under these plans are non-qualified stock options andmay be granted to each person who was a member of theCompany’s Board of Directors on April 21, 1997 and February25, 1993, respectively, and who was not an employee or offi-cer of the Company. The 1997 and 1993 Director Plansauthorized the grant of options for up to 200,000 shares and40,000 shares of common stock, respectively. Two directorswere entitled to participate in the Director Plans with eachreceiving a grant of options as of February 12, 1998 for

of grant. Options granted under all stock option plans afterJanuary 1, 1993 will expire not more than ten years fromthe date of grant (five years in the case of ISOs granted toten percent shareholders). The outstanding options expireat various dates through 2008. Options granted terminatewithin a specified period of time following termination of anoptionee’s employment or position as a director or consult-ant with the Company.

10. Fair Value of Financial InstrumentsThe carrying amount of cash, cash equivalents, accountsreceivable, short-term debt, accounts payable, and accruedliabilities approximates their fair value because of the shortduration of these instruments.

11. CommitmentsThe Company has several noncancelable operating leases,primarily for warehousing and office space, expiring at vari-ous dates through 2004. These leases contain renewaloptions for periods ranging from one to three years andrequire the Company to pay its proportionate share of utili-ties, taxes, and insurance. Rent expense under these leas-es for 1998, 1997 and 1996 was $2.5 million, $2.3 million,and $2.5 million, respectively.

Future minimum lease payments under these leases are:1999 - $2.9 million; 2000 - $2.1 million; 2001 - $2.0 million;2002 - $1.7 million; 2003 - $1.4 million; and 2004 - $1.3 million.

12. ContingenciesThe Company has agreements with the IndustrialDevelopment Authority of Ireland (“IDA”) under which theCompany receives grant monies for costs incurred formachinery, 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 millionand $1.3 million, respectively. Such grant monies are subjectto the Company meeting certain employment goals andmaintaining operations in Ireland until termination of therespective agreements. The total cumulative amounts ofcapital grant claims submitted and received throughDecember 31, 1998 for the Galway facility were approxi-mately $12.8 million and $9.4 million, respectively. The totalcumulative amount of capital grant claims submitted throughDecember 31, 1998 for the Castlebar facility was $1.3 mil-lion; no capital grant claims had been received for theCastlebar facility. Under separate agreements with the IDA,the Company receives direct reimbursement of trainingcosts at its Galway and Castlebar facilities for up to $3,000and $12,500, respectively, per new employee hired. Thetotal cumulative amounts of training grant claims submittedand received through December 31, 1998 for the Galwayfacility were approximately $1.3 million and $1.3 million,respectively. The total cumulative amount of training grantclaims submitted through December 31, 1998 for theCastlebar facility was approximately $1.0 million; no traininggrant claims had been received for the Castlebar facility.

In addition, the Company executed agreements in 1994with an unrelated company to acquire the 280,000 squarefoot manufacturing and distribution facility presently occu-pied for one (1) Irish Pound (equivalent to approximately$1.50). As additional consideration for the facility, theCompany assumed a contingent liability of approximately$5.2 million as part of the Company’s agreement with theIDA. The contingent liability is canceled upon successfulcompletion of the terms of the agreement.
