PART I

ITEM 1. BUSINESS.

In this Annual Report on Form 10-K, "WESCO" refers to WESCO International,
Inc., and its subsidiaries and its predecessors unless the context otherwise
requires. References to "we," "us," "our" and the "Company" refer to WESCO and
its subsidiaries. Our subsidiaries include WESCO Distribution, Inc. ("WESCO
Distribution") and WESCO Distribution Canada, Inc. ("WESCO Canada"), both of
which are wholly-owned by WESCO.

THE COMPANY

With sales of approximately $3.3 billion in 2002, we are a leading North
American provider of electrical construction products and electrical and
industrial maintenance, repair and operating supplies, commonly referred to as
"MRO." We are the second largest distributor in the estimated $72 billion U.S.
electrical distribution industry, and the largest provider of integrated supply
services. Our integrated supply solutions and outsourcing services are designed
to fulfill a customer's industrial MRO procurement needs through a highly
automated, proprietary electronic procurement and inventory replenishment
system. This allows our customers to consolidate suppliers and reduce their
procurement and operating costs. We have over 350 branches and five distribution
centers located in 48 states, nine Canadian provinces, Puerto Rico, Mexico,
Guam, the United Kingdom, Nigeria and Singapore. We serve over 100,000 customers
worldwide, offering over 1,000,000 products from over 24,000 suppliers. Our
diverse customer base includes a wide variety of industrial companies;
contractors for industrial, commercial and residential projects; utility
companies; and commercial, institutional and governmental customers. Our leading
market positions, extensive geographic reach, broad product and service
offerings and acquisition program have enabled us to compete effectively against
the companies in our industry.

INDUSTRY OVERVIEW

The electrical distribution industry serves customers in a number of
markets including the industrial, commercial, construction and utility markets.
Electrical distributors, such as WESCO, provide logistical and technical
services for customers by bundling together a wide range of products typically
required for the construction and maintenance of electrical supply networks,
including wire, lighting, distribution and control equipment and a wide variety
of electrical supplies. This distribution channel enables customers to
efficiently access a broad range of products and has the capacity to deliver
value-added services. Customers are increasingly demanding that distributors
provide a broader and more complex package of services as they seek to outsource
non-core functions and achieve documented cost savings in purchasing, inventory
and supply chain management.

ELECTRICAL DISTRIBUTION. The U.S. electrical distribution industry had
sales of approximately $72 billion in 2002. While overall weakness in the
current economic environment has contributed to recent industry sales decline of
approximately $2 billion since 2000, industry growth has averaged 5% per year
from 1985 to 2002. This expansion has been driven by general economic growth,
increased use of electrical products in businesses and industries, new products
and technologies, and customers who are seeking to more efficiently purchase a
broad range of products and services from a single point of contact, thereby
eliminating the costs and expenses of purchasing directly from manufacturers or
multiple sources. The U.S. electrical distribution industry is highly
fragmented. The four national distributors, including WESCO, account for
approximately 19% of estimated total industry sales.

INTEGRATED SUPPLY. The market for integrated supply services has more than
doubled from $5 billion in 1997 to over $12 billion in 2001, an increase of 25%
per year. Recent projections estimate that the integrated supply market will
reach $26 billion by 2005. Growth is being driven by the desire of large
industrial companies to reduce operating expenses by implementing comprehensive
third-party programs, which outsource the cost-intensive procurement, stocking
and administrative functions associated with the purchase and consumption of MRO
supplies. For our customers, these costs can account for over 50% of the total
costs for MRO products and services. The total potential in the United States
for integrated supply services, measured as all purchases of industrial MRO
supplies and services, is currently estimated to be approximately $260 billion.

COMPETITIVE STRENGTHS

MARKET LEADERSHIP. Our ability to manage large construction projects and
complex multi-site plant maintenance programs and procurement projects that
require special sourcing, technical advice, logistical support and locally based
service has enabled us to establish leadership positions in our principal
markets. We have utilized these skills to generate significant revenues in
industries with intensive use of electrical and MRO products, including
electrical contracting, utilities, original equipment manufacturing, process
manufacturing and other commercial, institutional and governmental entities. We
also have extended our position within these industries to expand our customer
base.

VALUE-ADDED SERVICES. We are a leader in providing a wide range of
services and procurement solutions that draw on our product knowledge, supply
and logistics expertise and systems capabilities, enabling our customers to
reduce supply chain costs and improve efficiency. These programs include:

- National Accounts -- we coordinate product supply and materials
management activities for MRO supplies, project needs and direct
material for customers with multiple locations who seek purchasing
leverage through a single electrical products provider;

- Integrated Supply -- we design and implement programs that enable
our customers to significantly reduce the number of MRO suppliers
they use through services that include highly automated, proprietary
electronic procurement and inventory replenishment systems and
on-site materials management and logistics services; and

- Construction National Accounts -- we have a dedicated team of
experienced construction sales management personnel to service the
needs of the regional and national contractors. Top engineering and
construction firms which specialize in major projects such as
airport expansions, power plants and oil and gas facilities are also
a focus group.

BROAD PRODUCT OFFERING. We provide our customers with a broad product
selection consisting of over 1,000,000 electrical, industrial and data
communications products sourced from over 24,000 suppliers. Our broad product
offering enables us to meet virtually all of a customer's electrical product and
other MRO requirements.

EXTENSIVE DISTRIBUTION NETWORK. Our distribution network consists of over
350 branches and five distribution centers located in 48 states, nine Canadian
provinces, Puerto Rico, Mexico, Guam, the United Kingdom, Nigeria and Singapore.
This extensive network, which would be extremely difficult and expensive to
duplicate, allows us to:

- maintain local sourcing of customer service, technical support and
sales coverage;

- tailor branch products and services to local customer needs;

- offer multi-site distribution capabilities to large customers and
national accounts; and

- provide same-day deliveries.

LOW COST OPERATOR. Our competitive position has been enhanced by our low
cost position, which is based on:

- extensive use of automation and technology;

- centralization of functions such as purchasing and accounting;

- strategically located distribution centers;

- purchasing economies of scale; and

- incentive programs that increase productivity and encourage
entrepreneurship.


3


Our low cost position enables us to generate a significant amount of cash flow
as the capital investment required to maintain our business is low. This cash
flow is available for debt reduction, strategic acquisitions and continued
investment in the growth of the business.

BUSINESS STRATEGY

Our objective is to be the leading provider of electrical products and
other MRO supplies and services to companies in North America and selected
international markets. In achieving this leadership position, our goal is to
grow earnings at a faster rate than sales by focusing on margin enhancement and
continuous productivity improvement. Our growth strategy leverages our existing
strengths and focuses on developing new initiatives and programs.

ENHANCE OUR LEADERSHIP POSITION IN ELECTRICAL DISTRIBUTION. We intend to
leverage our extensive market presence and brand equity in the WESCO name to
further our leadership position in electrical distribution. We are focusing our
sales and marketing on existing industries where we are expanding our product
and service offerings as well as targeting new clients, both within industries
we currently serve and in new markets which provide significant growth
opportunities. Markets where we believe such opportunities exist include retail,
education, financial services and health care. We are the second largest
electrical distributor in the United States and, through our value-added
products and services, we believe we have become the industry leader in serving
several important and growing markets including:

- industrial customers with large, complex plant maintenance
operations, many of which require a national multi-site service
solution for their electrical product needs;

- large contractors for major industrial and commercial construction
projects;

- the electric utility industry; and

- manufacturers of factory-built homes, recreational vehicles and
other modular structures.

GROW NATIONAL ACCOUNTS PROGRAMS. From 1994 through 2002, revenue from our
national accounts program increased in excess of 10% annually. We will continue
to invest in the expansion of this program. Through our national accounts
program, we coordinate electrical MRO procurement and purchasing activities
primarily for large industrial and commercial companies across multiple
locations. We have well-established relationships with over 300 companies,
providing us with a recurring base of revenue through multi-year agreements. Our
objective is to continue to increase revenue generated through our national
accounts program by:

- offering existing national account customers new products and
services and serving additional locations;

- extending certain established national account relationships to
include integrated supply; and

- expanding our customer base by leveraging our existing industry
expertise in markets we currently serve as well as entering into new
markets.

FOCUS ON CONSTRUCTION NATIONAL ACCOUNTS. We are increasing our focus on
large construction, renovation and institutional projects. We seek to secure new
major project contracts through:

- active national marketing of our demonstrated project management
capabilities;

- further development of relationships with leading regional and
national contractors and engineering firms;

- close coordination with national account customers on their major
project requirements; and

- offering an integrated supply service approach to contractors for
major projects.

EXTEND OUR LEADERSHIP POSITION IN INTEGRATED SUPPLY. We are the largest
provider of integrated supply services for MRO goods and services in the United
States. We provide a full complement of outsourcing solutions, focusing on
improving the supply chain management process for our customers' indirect
purchases. Our integrated supply programs replace the traditional multi-vendor,
resource-intensive procurement process with a single, outsourced, fully
automated process capable of managing all MRO and related service requirements.
Our solutions range from timely product delivery to assuming full responsibility
for the entire procurement function. Our customers include some of the largest
industrial companies in the United States. We intend to expand our leadership
position as the largest integrated supply service provider by:

- continuing to tailor our proven and profitable business model to the
scale and scope of our customers' operations;

- maximizing the use of our highly automated proprietary information
systems;

- leveraging established relationships with our large industrial
customer base, especially among existing national account customers
who could benefit from our integrated supply model; and

- being a low cost provider of integrated supply services.

We intend to utilize these competitive strengths to increase our
integrated supply sales to both new and existing customers, including our
existing national account customers.

GAIN SHARE IN KEY LOCAL MARKETS. Significant opportunities exist to gain
market share in the highly fragmented local markets. We intend to increase our
market share in key geographic markets through a combination of increased sales
and marketing efforts at existing branches, acquisitions that expand our product
and customer base and new branch openings. We intend to leverage our existing
relationships with preferred suppliers to increase sales of their products in
local markets through various initiatives, including sales promotions,
cooperative marketing efforts, direct participation by suppliers in national
accounts implementation, dedicated sales forces and product exclusivity. To
promote growth, we have instituted a compensation system for branch managers
that encourages our branch managers to increase sales and optimize business
activities in their local markets, including managing the sales force,
configuring inventories, targeting potential customers for marketing efforts and
tailoring local service options.

PURSUE STRATEGIC ACQUISITIONS. Since 1995, we have completed and
successfully integrated 25 acquisitions, which represent annual sales of
approximately $1.4 billion. We believe that the highly fragmented nature of the
electrical and industrial MRO distribution industry will continue to provide us
with acquisition opportunities. Our most recent acquisition was completed in
March 2001. We have not been as active in pursuing acquisition candidates given
the weak economy and the uncertain future earnings streams of acquisition
candidates. We would expect our acquisition activities to increase as the
economy improves. We expect that any future acquisitions will be financed out of
available internally generated funds, additional debt and/or the issuance of
equity securities. However, our ability to make acquisitions will be subject to
our compliance with certain conditions under the terms of our revolving credit
facility. See Part II, Item 7. - "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources" for a further description of the revolving credit facility.

EXPAND PRODUCT AND SERVICE OFFERINGS. We continue to build on our
demonstrated ability to introduce new products and services to meet existing
customer demands and capitalize on new market opportunities. In addition, we
have the platform to sell integrated lighting control and power distribution
equipment in a single package for multi-site specialty retailers, restaurant
chains and department stores. These are strong growth markets where our national
accounts strategies and logistics infrastructure provide significant benefits
for our customers.

LEVERAGE OUR E-COMMERCE AND INFORMATION SYSTEM CAPABILITIES. We conduct a
significant amount of business electronically. Our electronic transaction
management capabilities lower costs and shorten cycle time in the supply chain
process for us and for our customers. We intend to continue to invest in
information technology to create more effective linkages with both customers and
suppliers.


5


EXPAND OUR INTERNATIONAL OPERATIONS. Our international sales, the majority
of which are in Canada, accounted for approximately 11% of total sales in 2002.
We believe that there is significant additional demand for our products and
services outside the United States and Canada. Many of our multinational
domestic customers are seeking distribution, integrated supply and project
management solutions globally. Our approach to international operations is
consistent with our domestic philosophy. We follow our established customers and
pursue business that we believe utilizes and extends our existing capabilities.
This strategy of working through well-developed customer and supplier
relationships significantly reduces risks and provides the opportunity to
establish a profitable business. We have five locations in Mexico headquartered
in Tlalnepantla that serve all of metropolitan Mexico City and the Federal
District and the states of Mexico, Morelos and Hidalgo. We continue to pursue
growth opportunities in existing locations such as Aberdeen, Scotland and
London, England, which support our sales efforts in Europe and the former Soviet
Union. We have an operation in Nigeria to serve West Africa and an office in
Singapore to support our sales to customers in Asia. We are working toward
forming strategic alliances in critical markets, where appropriate.

PRODUCTS AND SERVICES

Products

Our network of branches and distribution centers stocks over 215,000
product stock keeping units ("SKUs"). Each branch tailors its inventory to meet
the needs of the customers in its local market, typically stocking approximately
4,000 to 8,000 SKUs. Our integrated supply business allows our customers to
access over 1,000,000 products for direct shipment.

Representative products that we sell include:

- Electrical Supplies. Fuses, terminals, connectors, boxes, fittings,
tools, lugs, tape and other MRO supplies

- Industrial Supplies. Cutting and other tools, abrasives, filters and
safety equipment

- Distribution. Circuit breakers, transformers, switchboards,
panelboards and busway

- Lighting. Lamps, fixtures and ballasts

- Wire and Conduit. Wire, cable and metallic and non-metallic conduit

- Control, Automation and Motors. Motor control devices, drives,
programmable logic controllers, pushbuttons and operator interfaces

- Data Communications. Premise wiring, patch panels, terminals and
connectors

We purchase products from a diverse group of over 24,000 suppliers. In
2002, our ten largest suppliers accounted for approximately 33% of our
purchases. The largest of these was Eaton Corporation, through its Cutler-Hammer
division, accounting for approximately 13% of total purchases. No other supplier
accounted for more than 5% of total purchases.

Our supplier relationships are important to us, providing access to a wide
range of products, technical training and sales and marketing support. We have
preferred supplier agreements with approximately 179 of our suppliers and
purchase approximately 65% of our stock inventory pursuant to these agreements.
Consistent with industry practice, most of our agreements with suppliers,
including both distribution agreements and preferred supplier agreements, are
terminable by either party on 60 days' notice or less.

Services

In conjunction with product sales, we offer customers a wide range of
services and procurement solutions that draw on our product and supply
management expertise and systems capabilities. These services include national


6


accounts programs, integrated supply programs and major project programs. We are
responding to the needs of our customers, particularly those in processing and
manufacturing industries. To more efficiently manage the MRO process on behalf
of our customers, we offer a range of supply management services, including:

- outsourcing of the entire MRO purchasing process;

- providing technical support for manufacturing process improvements
using state-of-the-art automated solutions;

- implementing inventory optimization programs;

- participating in joint cost savings teams;

- assigning our employees as on-site support personnel;

- recommending energy-efficient product upgrades; and

- offering safety and product training for customer employees.

National accounts programs. The typical national account customer is a
Fortune 500 industrial company, a large utility or other major customer, in each
case with multiple locations. Our national accounts programs are designed to
provide customers with total supply chain cost reductions by coordinating
purchasing activity for MRO supplies across multiple locations. Comprehensive
implementation plans establish jointly managed teams at the local and national
level to prioritize activities, identify key performance measures and track
progress against objectives. We involve our preferred suppliers early in the
implementation process, where they can contribute expertise and product
knowledge to accelerate program implementation and the achievement of cost
savings and process improvements.

Integrated supply programs. Our integrated supply programs offer customers
a variety of services to support their objectives for improved supply chain
management. We integrate our personnel, product and distribution expertise,
electronic technologies and service capabilities with the customer's own
internal resources to meet particular service requirements. Each integrated
supply program is uniquely configured to deliver a significant reduction in the
number of MRO suppliers, reduce total procurement costs, improve operating
controls and lower administrative expenses. Our solutions range from
just-in-time fulfillment to assuming full responsibility for the entire
procurement function for all indirect purchases. We believe that customers will
increasingly seek to utilize us as an "integrator," responsible for selecting
and managing the supply of a wide range of MRO and original equipment
manufacturers ("OEMs") products.

Construction national accounts. We have a construction national accounts
group, comprised of our most experienced construction management personnel,
which focuses on serving the complex needs of North America's largest
engineering and construction firms and the top 50 U.S. electrical contractors on
a multi-regional basis. These contractors typically specialize in building
industrial sites, water treatment plants, airport expansions, healthcare
facilities, correctional institutions and new sports stadiums.

MARKETS AND CUSTOMERS

We have a large base of approximately 100,000 customers diversified across
our principal markets. One customer accounted for over 3% of 2002 sales and
another customer accounted for over 2% of 2002 sales. Except for these two
customers, no other customer accounted for more than 2% of 2002 sales.

Industrial customers. Sales to industrial customers, which include
numerous manufacturing and process industries, and OEMs accounted for
approximately 42% of our sales in 2002.

MRO products are needed to maintain and upgrade the electrical and
communications networks at all industrial sites. Expenditures are greatest in
the heavy process industries, such as food processing, pulp and paper and
petrochemical. Typically, electrical MRO is the first or second ranked product
category by purchase value for total MRO requirements for an industrial site.
Other MRO product categories include, among others, lubricants, pipe,


7


valves and fittings, fasteners, cutting tools and power transmission products.

OEM customers incorporate electrical components and assemblies into their
own products. OEMs typically require a reliable, high volume supply of a narrow
range of electrical items. Customers in this segment are particularly service
and price sensitive due to the volume and the critical nature of the product
used, and they also expect value-added services such as design and technical
support, just-in-time supply and electronic commerce.

Electrical contractors. Sales to electrical contractors accounted for
approximately 35% of our sales in 2002. These customers range from large
contractors for major industrial and commercial projects, the customer types we
principally serve, to small residential contractors, which represent a small
portion of our sales. Electrical products purchased by electrical
sub-contractors typically account for approximately 40% to 50% of their
installed project cost, and, therefore, accurate cost estimates and competitive
material costs are critical to a contractor's success in obtaining profitable
projects.

Utilities. Sales to utilities accounted for approximately 17% of our sales
in 2002. This market includes large investor-owned utilities, rural electric
cooperatives and municipal power authorities. We provide our utility customers
with power line products and an extensive range of supplies to meet their MRO
and capital projects needs. Full materials management and procurement
outsourcing arrangements are also important in this market as cost pressures and
deregulation cause utility customers to streamline purchasing and inventory
control practices.

Commercial, institutional and governmental customers ("CIG"). Sales to CIG
customers accounted for approximately 6% of our sales in 2002. This fragmented
market includes schools, hospitals, property management firms, retailers and
government agencies of all types. Through our WR Controls Branch, we have a
platform to sell integrated lighting control and distribution equipment in a
single package for multi-site specialty retailers, restaurant chains and
department stores.

DISTRIBUTION NETWORK

Branch network. We have over 350 branches, of which approximately 290 are
located in the United States, approximately 50 are located in Canada and the
remainder are located in Puerto Rico, Mexico, Guam, the United Kingdom, Nigeria
and Singapore. Over the last three years, we have opened approximately seven
branches per year, principally to service national account customers. In
addition to consolidations in connection with acquisitions, we occasionally
close or consolidate existing branch locations to improve operating efficiency.

Distribution centers. To support our branch network, we have five
distribution centers located in the United States and Canada, including
facilities located near Pittsburgh, Pennsylvania, serving the Northeast and
Midwest United States; near Reno, Nevada, serving the Western United States;
near Memphis, Tennessee, serving the Southeast and Central United States; near
Montreal, Quebec, serving Eastern and Central Canada; and near Vancouver,
British Columbia, serving Western Canada.

Our distribution centers add value for our branches and customers through
the combination of a broad and deep selection of inventory, on-line ordering,
same day shipment and central order handling and fulfillment. Our distribution
center network reduces the lead-time and improves the reliability of our supply
chain, giving us a distinct competitive advantage in customer service.
Additionally, the distribution centers reduce the time and cost of supply chain
activities through automated replenishment and warehouse management systems, and
economies of scale in purchasing, inventory management, administration and
transportation.

SALES ORGANIZATION

General sales force. Our general sales force is based at the local
branches and comprises approximately 2,100 of our employees, almost half of whom
are outside sales representatives and the remainder are inside sales personnel.
Outside sales representatives are paid under a compensation structure which is
primarily weighted towards commissions. They are responsible for making direct
customer calls, performing on-site technical support,


8


generating new customer relations and developing existing territories. The
inside sales force is a key point of contact for responding to routine customer
inquiries such as price and availability requests and for entering and tracking
orders.

National accounts. Our national accounts sales force is comprised of an
experienced group of sales executives who negotiate and administer contracts,
coordinate branch participation and identify sales and service opportunities.
National accounts managers' efforts target specific customer industries,
including automotive, pulp and paper, petrochemical, steel, mining and food
processing.

Data communications. Sales of premise cable, connectors, hardware, network
electronics and outside plant products are generated by our general sales force
and a dedicated group of outside and inside data communications sales
representatives. They are supported by a centralized customer service center and
additional resources in product management, purchasing, inventory control and
sales management.

Construction national accounts. We have a sales management group,
comprised of our most experienced construction management personnel, which
focuses on serving the complex needs of North America's largest engineering and
construction firms and the top regional and national electrical contractors.
These contractors typically specialize in large, complex projects such as
building industrial sites, water treatment plants, airport expansions,
healthcare facilities, correctional institutions and new sports stadiums.

E-Commerce. We established our initial electronic catalog on the Internet
in 1996. Since that time, we have worked with a variety of large customers to
establish customized electronic catalogs for their use in internal systems.
Additionally, in 1999 we began a process of providing electronic catalogs to
multiple e-commerce service providers, trade exchanges and industry specific
electronic commerce portals. Our primary e-business strategy is to serve
existing customers by tailoring our catalog and Internet-based procurement
applications to their internal systems or through their preferred technology and
trading exchange partnerships. We believe that we lead our industry in rapid
e-implementation to customers' procurement systems and provide integrated
procurement functionality using "punch-out" technology, a direct
system-to-system link with our customers.

We continue to enhance "WESCOExpress," a direct ship fulfillment operation
responsible for supporting smaller customers and select national account
locations. Customers can order over 65,000 electrical and data communications
products stocked in our warehouses through a centralized customer service center
or over the Internet on WESCOdirect.com. We use a proactive telesales approach
utilizing catalogs, direct mail, e-mail and personal phone selling to provide a
high level of customer service. A new 2003-2004 Buyer's Guide is in production
and scheduled for release in the third quarter of 2003.

INTERNATIONAL OPERATIONS

To serve the Canadian market, we operate a network of approximately 50
branches in nine provinces. Branch operations are supported by two distribution
centers located near Montreal and Vancouver. With sales of approximately US$300
million, Canada represented 9.0% of our total sales in 2002. The Canadian market
for electrical distribution is considerably smaller than the U.S. market, with
roughly US$2.7 billion in total sales in 2002, according to industry sources.

We also have five locations in Mexico headquartered in Tlalnepantla, that
serve all of metropolitan Mexico City and the Federal District and the states of
Mexico, Morelos and Hidalgo.

We sell internationally through domestic export sales offices located
within North America and sales offices in international locations. WESCO
operations are in Aberdeen, Scotland and London, England to support sales
efforts in Europe and the former Soviet Union. We have an operation in Nigeria
to serve West Africa and an office in Singapore to support our sales to Asia.
All of the international locations have been established to primarily serve
WESCO's growing list of customers with global operations referenced under
National Accounts above.

MANAGEMENT INFORMATION SYSTEMS

Our branch information system, WESNET, provides processing for a full
range of our business operations, such


9


as customer service, inventory and logistics management, accounting and
administrative support. The branch system utilizes decision support, executive
information system analysis and retrieval capabilities to provide extensive
operational analysis and detailed income statement and balance sheet variance
and trend reporting at the branch level. The corporate system also provides
activity-based costing capabilities for analyzing profitability by customer,
sales representative and shipment type. Sales and margin trends and variances
can be analyzed by branch, customer, product category, supplier or account
representative.

The WESNET system operates as a distributed network of fully functional
operating units, and every branch (other than our Bruckner Integrated Supply
Division and certain acquired branches) utilizes its own computer system to
support local business activities. All branch operations are linked through a
wide area network to centralized information on inventory status in our
distribution centers as well as other branches and an increasing number of
on-line suppliers. Recent advances in WESNET capabilities make it possible to
consolidate administrative and procurement functions, and bring systematic
improvement through new pricing systems and controls.

We routinely process customer orders, shipping notices, suppliers'
purchase orders, and funds transfer via EDI transactions with our trading
partners. Our e-commerce strategy calls for more effective linkages to both
customers and suppliers through greater use of technological advances, including
Internet and electronic catalogs, enhanced EDI and other innovative
improvements.

Our integrated supply services are supported by our proprietary
procurement and inventory management systems. These systems provide a fully
integrated, flexible supply chain platform that currently handles over 95% of
our integrated supply customers' transactions electronically. Our configuration
options for a customer range from on-line linkages to the customer's business
and purchasing systems, to total replacement of a customer's procurement and
inventory management system for MRO supplies.

COMPETITION

We operate in a highly competitive industry. We compete directly with
national, regional and local providers of electrical and other industrial MRO
supplies. Competition is primarily focused on the local service area, and is
generally based on product line breadth, product availability, service
capabilities and price. Another source of competition is buying groups formed by
smaller distributors to increase purchasing power and provide some cooperative
marketing capability. While increased buying power may improve the competitive
position of buying groups locally, we believe these groups have not been able to
compete effectively with us for national account customers due to the difficulty
in coordinating a diverse ownership group. During 1999 and 2000, numerous
special purpose Internet-based procurement service companies, auction
businesses, and trade exchanges were organized. Many of them targeted industrial
MRO and contractor customers of the type served by WESCO. We responded with our
own e-commerce capabilities and believe that we have successfully outpaced our
competitors in the deployment of electronic catalogs and Internet-based
connectivity with more than 50 national customers.

EMPLOYEES

As of December 31, 2002, we had approximately 5,400 employees worldwide,
of which approximately 4,700 were located in the United States and approximately
700 in Canada and our other international locations. Less than 5% of our
employees are represented by unions. We believe our labor relations are
generally good.

INTELLECTUAL PROPERTY

Our trade and service marks, including "WESCO," "the extra effort
people(R)," and the running man design, are filed in the U.S. Patent and
Trademark Office, the Canadian Trademark Office and the Mexican Instituto de la
Propriedad Industrial.

ENVIRONMENTAL MATTERS

Our facilities and operations are subject to federal, state and local laws
and regulations relating to environmental


10


protection and human health and safety. Some of these laws and regulations may
impose strict, joint and several liability on certain persons for the cost of
investigation or remediation of contaminated properties. These persons may
include former, current or future owners or operators of properties, and persons
who arranged for the disposal of hazardous substances. Our owned and leased real
property may give rise to such investigation, remediation and monitoring
liabilities under environmental laws. In addition, anyone disposing of certain
products we distribute, such as ballasts, fluorescent lighting and batteries,
must comply with environmental laws that regulate certain materials in these
products.

We believe that we are in compliance, in all material respects, with
applicable environmental laws. As a result, we will not make significant capital
expenditures for environmental control matters either in the current year or in
the near future.

FORWARD LOOKING INFORMATION

This Annual Report on Form 10-K contains various "forward looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995. These statements involve certain unknown risks and uncertainties,
including, among others, those contained in Item 1, "Business" and Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." When used in this Annual Report on Form 10-K, the words
"anticipates," "plans," "believes," "estimates," "intends," "expects,"
"projects" and similar expressions may identify forward looking statements,
although not all forward looking statements contain such words. Such statements,
including, but not limited to, our statements regarding business strategy,
growth strategy, productivity and profitability enhancement, competition, new
product and service introductions and liquidity and capital resources are based
on management's beliefs, as well as on assumptions made by, and information
currently available to, management, and involve various risks and uncertainties,
some of which are beyond our control. Our actual results could differ materially
from those expressed in any forward looking statement made by or on our behalf.
In light of these risks and uncertainties, there can be no assurance that the
forward looking information will in fact prove to be accurate. We have
undertaken no obligation to publicly update or revise any forward looking
statements, whether as a result of new information, future events or otherwise.

RISK FACTORS

Important factors that could cause actual results to differ materially
from the forward looking statements we make are described below. All forward
looking statements attributable to us or persons working on our behalf are
expressly qualified by the following cautionary statements:

OUR SUBSTANTIAL AMOUNT OF DEBT REQUIRES SUBSTANTIAL DEBT SERVICE OBLIGATIONS
THAT COULD ADVERSELY AFFECT OUR ABILITY TO FULFILL OUR OBLIGATIONS AND COULD
LIMIT OUR GROWTH AND IMPOSE RESTRICTIONS ON OUR BUSINESS.

We are and will continue to be for the foreseeable future significantly
leveraged. As of December 31, 2002, we had $418.0 million of consolidated
indebtedness and stockholders' equity of $169.3 million. We and our subsidiaries
may incur additional indebtedness in the future, subject to certain limitations
contained in the instruments governing our indebtedness. Accordingly, we will
have significant debt service obligations. These amounts exclude WESCO's
accounts receivable securitization program, through which WESCO sells accounts
receivable to a third party conduit and removes these receivables from its
consolidated balance sheet. See Part II, Item 7. -"Management's Discussion and
Analysis of Financial Condition and Results of Operations-Critical Accounting
Policies and Estimates."

Our debt service obligations have important consequences, including the
following:

- a substantial portion of cash flow from our operations will be
dedicated to the payment of principal and interest on our
indebtedness, thereby reducing the funds available for operations,
future business opportunities and acquisitions and other purposes
and increasing our vulnerability to adverse general economic and
industry conditions;

- our ability to obtain additional financing in the future may be
limited;


11


- approximately $110 million of our indebtedness is at variable rates
of interest, which will make us vulnerable to increases in interest
rates;

- we are substantially more leveraged than certain of our competitors,
which might place us at a competitive disadvantage; and

- we may be hindered in our ability to adjust rapidly to changing
market conditions.

Our ability to make scheduled payments of the principal of, or to pay
interest on, or to refinance our indebtedness and to make scheduled payments
under our operating leases or to fund planned capital expenditures or finance
acquisitions will depend on our future performance, which to a certain extent is
subject to economic, financial, competitive and other factors beyond our
control. There can be no assurance that our business will continue to generate
sufficient cash flow from operations in the future to service our debt, make
necessary capital expenditures or meet other cash needs. If unable to do so, we
may be required to refinance all or a portion of our existing debt, to sell
assets or to obtain additional financing. In addition, our Receivables Facility
requires an annual renewal of its terms. The current arrangement expires on June
20, 2003. There can be no assurance that available funding or that any sale of
assets or additional financing would be possible in amounts on terms favorable
to us. See Part II, Item 7. - "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Liquidity and Capital Resources."

RESTRICTIVE DEBT COVENANTS CONTAINED IN OUR REVOLVING CREDIT FACILITY AND THE
INDENTURE TO OUR SENIOR SUBORDINATED NOTES MAY LIMIT OUR ABILITY TO TAKE CERTAIN
ACTIONS.

The revolving credit facility and the indenture contain financial and
operating covenants that will limit the discretion of our management with
respect to certain business matters including, incurring additional indebtedness
and paying dividends. The revolving credit facility also requires us to meet
certain fixed charge tests depending on credit line availability. Our ability to
comply with these and other provisions of the revolving credit facility and the
indenture may be affected by changes in economic or business conditions or other
events beyond our control. A failure to comply with the obligations contained in
the revolving credit facility or the indenture could result in an event of
default under either the revolving credit facility or the indenture which could
result in acceleration of the related debt and the acceleration of debt under
other instruments evidencing indebtedness that may contain cross-acceleration or
cross-default provisions. If the indebtedness under the revolving credit
facility were to be accelerated, there can be no assurance that our assets would
be sufficient to repay in full such indebtedness and our other indebtedness. See
Part II, Item 7. - "Management's Discussion and Analysis of Financial Condition
and Results of Operations ?- Liquidity and Capital Resources."

DOWNTURNS IN THE ELECTRICAL DISTRIBUTION INDUSTRY HAVE HAD IN THE PAST, AND MAY
IN THE FUTURE HAVE, AN ADVERSE EFFECT ON OUR SALES AND PROFITABILITY.

The electrical distribution industry is affected by changes in economic
conditions, including national, regional and local slowdowns in construction and
industrial activity, which are outside our control. Our operating results may
also be adversely affected by increases in interest rates that may lead to a
decline in economic activity, particularly in the construction market, while
simultaneously resulting in higher interest payments under the revolving credit
facility. In addition, during periods of economic slowdown such as the one we
are currently experiencing, our credit losses could increase. There can be no
assurance that economic slowdowns, adverse economic conditions or cyclical
trends in certain customer markets will not have a material adverse effect on
our operating results and financial condition.

AN INCREASE IN COMPETITION COULD DECREASE SALES OR EARNINGS.

We operate in a highly competitive industry. We compete directly with
national, regional and local providers of electrical and other industrial MRO
supplies. Competition is primarily focused in the local service area and is
generally based on product line breadth, product availability, service
capabilities and price. Other sources of competition are buying groups formed by
smaller distributors to increase purchasing power and provide some cooperative
marketing capability. During 1999 and 2000, numerous special purpose
Internet-based procurement service companies, auction businesses and trade
exchanges were organized. Many of them targeted industrial MRO


12


and contractor customers of the type served by us. While the entrants did not
have a noticeable impact on our business we expect that new competitors could
develop over time as Internet-based enterprises become more established and
refine their service capabilities.

Some of our existing competitors have, and new market entrants may have,
greater financial and marketing resources than we do. To the extent existing or
future competitors seek to gain or retain market share by reducing prices, we
may be required to lower our prices, thereby adversely affecting financial
results. Existing or future competitors also may seek to compete with us for
acquisitions, which could have the effect of increasing the price and reducing
the number of suitable acquisitions. In addition, it is possible that
competitive pressures resulting from the industry trend toward consolidation
could affect growth and profit margins.

LOSS OF KEY SUPPLIERS OR LACK OF PRODUCT AVAILABILITY COULD DECREASE SALES AND
EARNINGS.

Most of our agreements with suppliers are terminable by either party on 60
days' notice or less. Our ten largest suppliers in 2002 accounted for
approximately 33% of our purchases for the period. Our largest supplier was
Eaton Corporation, through its Cutler-Hammer division, accounting for
approximately 13% of our purchases. The loss of, or a substantial decrease in
the availability of, products from any of these suppliers, or the loss of key
preferred supplier agreements, could have a material adverse effect on our
business. In addition, supply interruptions could arise from shortages of raw
materials, labor disputes or weather conditions affecting products or shipments,
transportation disruptions, or other reasons beyond our control. An interruption
of operations at any of our five distribution centers could have a material
adverse effect on the operations of branches served by the affected distribution
center. Furthermore, we cannot be certain that particular products or product
lines will be available to us, or available in quantities sufficient to meet
customer demand. Such limited product access could put us at a competitive
disadvantage.

A DISRUPTION OF OUR INFORMATION SYSTEMS COULD INCREASE EXPENSES, DECREASE SALES
OR REDUCE EARNINGS.

A serious disruption of our information systems could have a material
adverse effect on our business and results of operations. Our computer systems
are an integral part of our business and growth strategies. We depend on our
information systems to process orders, manage inventory and accounts receivable
collections, purchase products, ship products to our customers on a timely
basis, maintain cost-effective operations and provide superior service to our
customers.

WESCO INTERNATIONAL'S CONTROLLING SHAREHOLDERS OWN APPROXIMATELY 44% OF ITS
COMMON STOCK AND CAN EXERCISE SIGNIFICANT INFLUENCE OVER OUR AFFAIRS.

Approximately 44% of the issued and outstanding shares of common stock of
WESCO International is held by Cypress and its affiliates. Accordingly, Cypress
and its affiliates can exercise significant influence over our affairs,
including the election of our directors, appointment of our management and
approval of actions requiring the approval of our stockholders, including the
adoption of amendments to our certificate of incorporation and approval of
mergers or sales of substantially all of our assets.

ITEM 2. PROPERTIES.

We have over 350 branches, of which approximately 290 are located in the
United States, approximately 50 are located in Canada and the remainder are
located in Puerto Rico, Mexico, Guam, the United Kingdom, Nigeria and Singapore.
Approximately 25% of branches are owned facilities, and the remainder are
leased.

The following table summarizes our distribution centers:



LOCATION SQUARE FEET LEASED/OWNED
-------- ----------- ------------

Warrendale, PA ......... 194,200 Owned
Sparks, NV ............. 196,800 Leased
Byhalia, MS ............ 148,000 Owned
Dorval, QE ............. 90,000 Leased
Burnaby, BC ............ 64,865 Owned


We also lease our 76,200 square foot headquarters in Pittsburgh,
Pennsylvania. We do not regard the real property associated with any single
branch location as material to our operations. We believe our facilities are in
good operating condition.

ITEM 3. LEGAL PROCEEDINGS.

From time to time, a number of lawsuits, claims and proceedings have been
or may be asserted against us relating to the conduct of our business, including
routine litigation relating to commercial and employment matters. While the
outcome of litigation cannot be predicted with certainty, and some of these
lawsuits, claims or proceedings may be determined adversely to the Company, the
Company does not believe, based on information presently available to it, that
the outcome of any of such pending matters is likely to have a material adverse
effect on the Company.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

No matters were submitted to a vote of the Company's security holders
during the fourth quarter of 2002.

PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

On May 17, 1999, WESCO completed its initial public offering of common
stock ("the Offering"). Our common stock is listed on the New York Stock
Exchange under the symbol "WCC." As of February 28, 2003, there were 40,455,493
shares of common stock and 4,653,131 shares of Class B common stock outstanding
and held by approximately 100 holders of record. We have not paid dividends on
the common stock, and do not presently plan to pay dividends in the foreseeable
future. It is currently expected that earnings will be retained and reinvested
to support either business growth or debt reduction. In addition, our revolving
credit facility and our indenture restrict our ability to pay dividends. See
Part II, Item 7. - "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources." The following
table sets forth the high and low close price of the shares of common stock for
the periods indicated.

WESCO's board of directors has authorized a $25 million share repurchase
program which expires in May 2003. WESCO's common stock may be purchased at
management's discretion, subject to meeting certain financial ratios in its
revolving credit facility, in open market transactions and the program may be
discontinued at any time. Under previous share repurchase programs, WESCO
purchased approximately 3.9 million shares of its common stock for approximately
$32.8 million pursuant to this program. No shares were repurchased during 2002.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

The following discussion should be read in conjunction with the audited
consolidated financial statements and notes thereto included elsewhere in this
Annual Report on Form 10-K.

GENERAL

WESCO's sales can be categorized as stock, direct ship and special order.
Stock orders are filled directly from existing inventory and generally represent
approximately 45% of total sales. Approximately 45% of WESCO's total sales are
direct ship sales. Direct ship sales are typically custom-built products, large
orders or products that are too bulky to be easily handled and, as a result, are
shipped directly to the customer from the supplier. Special orders are for
products that are not ordinarily stocked in inventory and are ordered based on a
customer's specific request. Special orders represent the remainder of total
sales. Gross profit margins on stock and special order sales are approximately
60% higher than those on direct ship sales. Although direct ship gross margins
are lower, operating profit margins are often comparable, since the product
handling and fulfillment costs associated with direct shipments are much lower.

WESCO has historically financed its working capital needs, capital
expenditures, acquisitions and new branch openings through internally generated
cash flow and borrowings under its credit facilities and funding through its
accounts receivable securitization program. During the initial phase of an
acquisition or new branch opening, WESCO typically incurs expenses related to
installing or converting information systems, training employees and other
initial operating activities. With some acquisitions, WESCO may incur expenses
in connection with the closure of any of its own redundant branches.
Historically, the costs associated with opening new branches, and closing
branches in connection with certain acquisitions, have not been material. WESCO
has accounted for its acquisitions under the purchase method of accounting.

WESCO is a leading consolidator in its industry, having acquired 25
companies since August 1995, representing annual sales of approximately $1.4
billion. Management distinguishes sales attributable to core operations
separately from sales of acquired businesses. The distinction between sales from
core operations and from acquired businesses is based on the Company's internal
records and on management estimates where the integration of acquired businesses
results in the closing or consolidation of branches. However, "core operations"
typically refer to all internally started branches and all acquired branches
that have been in operation for the entire current and prior year-to-date
periods. "Acquired businesses" generally refer to branch operations purchased by
WESCO where the branches have not been under WESCO ownership for the entire
current and prior year-to-date periods.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

WESCO's discussion and analysis of its financial condition and results of
operations are based upon WESCO's consolidated financial statements, which have
been prepared in accordance with accounting principles generally accepted in the
United States of America. The preparation of these financial statements requires
WESCO to make estimates and judgments that affect the reported amounts of
assets, liabilities, revenues and expenses, and related disclosure of contingent
assets and liabilities. On an on-going basis, WESCO evaluates its estimates,
including those related to supplier programs, bad debts, inventories, insurance
costs, goodwill, income taxes, restructuring cost, contingencies and litigation.
WESCO bases its estimates on historical experience and on various other
assumptions that are believed to be reasonable under the circumstances, the
results of which form the basis for making judgments about the carrying values
of assets and liabilities that are not readily apparent from other sources.
Actual results may differ from these estimates. If actual market conditions are
less favorable than those projected by management, additional adjustments to
reserve items may be required. WESCO believes the following critical accounting
policies affect its judgments and estimates used in the preparation of its
consolidated financial statements.

Allowance for Doubtful Accounts

WESCO maintains allowances for doubtful accounts for estimated losses
resulting from the inability of its customers to make required payments. WESCO
has a systematic procedure using estimates based on historical data and
reasonable assumptions of collectibility made at the local branch level and at
the consolidated corporate basis to calculate the allowance for doubtful
accounts. The allowance for doubtful accounts was $10.3 million at December


17


31, 2002 and $11.8 million at December 31, 2001. The total amount recorded as
selling, general and administrative expense related to bad debts was $9.0
million, $10.3 million and $10.0 million for 2002, 2001 and 2000, respectively.

Excess and Obsolete Inventory

WESCO writes down its inventory for estimated obsolescence or unmarketable
inventory equal to the difference between the cost of inventory and the
estimated market value based upon assumptions about future demand and market
conditions. A systematic procedure is used to determine excess and obsolete
inventory using historical data and reasonable assumptions for the percentage of
excess and obsolete inventory on a consolidated basis. The valuation allowance
for excess and obsolete inventories was $11.9 million at December 31, 2002 and
$16.8 million at December 31, 2001, respectively. Direct write-offs against the
reserve related to inventory disposals during 2002, totaled $6.4 million. The
total expense related to excess and obsolete inventories, included in cost of
goods sold, was $1.4 million, $2.6 million and $4.3 million for 2002, 2001 and
2000, respectively.

Supplier Rebates

WESCO receives rebates from certain suppliers based on contractual
arrangements with such suppliers. Since there is a lag between actual sales and
the rebates received from the suppliers WESCO must estimate the approximate
amount of rebates available at a specific date. The asset recorded for the
supplier rebate program is within other accounts receivable and was $15.9
million at December 31, 2002 and $23.5 million at December 31, 2001. The total
amount recorded as a reduction to cost of goods sold was $24.7 million, $31.4
million and $39.7 million for 2002, 2001 and 2000, respectively.

Goodwill

As described in Note 4 to the Consolidated Financial Statements, WESCO
tests goodwill for impairment annually or more frequently when events or
circumstances occur indicating goodwill might be impaired. This process involves
estimating fair value using discounted cash flow analyses. Considerable
management judgment is necessary to estimate discounted future cash flows.
Assumptions used for these estimated cash flows were based on a combination of
historical results and current internal forecasts. WESCO cannot predict certain
events that could adversely affect the reported value of goodwill, which totaled
$314.1 million at December 31, 2002 and $311.1 million at December 31, 2001.

Insurance Programs

WESCO uses commercial insurance for auto, workers' compensation, casualty
and health claims as a risk reduction strategy to minimize catastrophic losses.
Such strategy involves large deductibles where WESCO must pay all costs up to
the deductible amount. WESCO estimates its reserve based on historical incident
rates and costs. The total liability related to the insurance programs was $5.8
million at December 31, 2002 and $4.0 million at December 31, 2001.

Taxes

WESCO records its deferred tax assets at amounts that are expected to be
realized. WESCO is evaluating future taxable income and potential tax planning
strategies in assessing the potential need for a valuation allowance. Should
WESCO determine that it would not be able to realize all or part of its net
deferred tax asset in the future, an adjustment to the deferred tax asset would
be charged to income in the period such determination was made.

Accounts Receivable Securtitization Program

WESCO maintains an accounts receivable securitization program (the
"Receivables Facility"), whereby it sells, on a continuous basis, to WESCO
Receivables Corporation, a wholly-owned, special purpose company ("SPC"), an
undivided interest in all domestic accounts receivable. The SPC sells without
recourse to a third-party conduit, all the eligible receivables while
maintaining a subordinated interest, in the form of overcollateralization, in a
portion of the receivables.


18


WESCO accounts for the Receivables Facility in accordance with Statement
of Financial Accounting Standards No. 140, "Accounting for Transfers and
Servicing of Financial Assets and Extinguishments of Liabilities." At the time
the receivables are sold, the balances are removed from the balance sheet. The
Receivables Facility represents "off-balance sheet financing," since the
conduit's ownership interest in the accounts receivable of the SPC results in
the removal of accounts receivable from WESCO's consolidated balance sheets,
rather than resulting in the addition of a liability to the conduit.

WESCO believes that the terms of the agreements governing this facility
qualify our trade receivable sales transactions for "sale treatment" under
generally accepted accounting principles, which require WESCO to remove the
accounts receivable from our consolidated balance sheets. Absent this "sale
treatment," our consolidated balance sheet would reflect additional accounts
receivable and debt. Our consolidated statements of operations would not be
impacted, except that other expenses would be classified as interest expense.

2002 DEVELOPMENTS

Developments affecting the 2002 results of operations and financial
position of WESCO include the following:

Economic Trends

The electrical distribution industry experienced a continued overall sales
decline in the markets where WESCO participates. The 2002 decrease varies
dramatically depending upon the product category as well as the market channel
used to distribute such product. Based upon our internal estimates, certain of
our more significant competitors and suppliers, as a group, experienced an
average sales decline of approximately 7.5% in 2002. WESCO's net sales decreased
approximately 9.1% in 2002 due to lower capacity utilization by many of our
industrial and MRO customers, coupled with a lower level of plant expansion and
upgrading activity in 2002.

Refinancing

The Company has taken the following steps to improve its liquidity:

In March 2002, WESCO Distribution, Inc. entered into a $290 million
revolving credit agreement that is collateralized by substantially all inventory
owned by WESCO and also by the accounts receivable of WESCO Distribution Canada,
Inc. ("WESCO Canada"). Availability under the agreement, which matures in 2007,
is limited to the amount of eligible inventory and Canadian receivables applied
against certain advance rates. Proceeds from this agreement were used to retire
WESCO Distribution, Inc.'s existing revolving credit facility. Interest on this
new facility is at LIBOR plus a margin that ranges between 2.0% to 2.75%
depending upon the amount of excess availability under the facility. As long as
the average daily excess availability for both the preceding and projected
succeeding 90-day period is greater than $50 million, WESCO would be permitted
to make acquisitions and repurchase outstanding public stock and bonds. The
above permitted transactions would also be allowed if such excess availability
is between $25 million and $50 million and WESCO's fixed charge coverage ratio,
as defined by the agreement, is at least 1.25 to 1.0 after taking into
consideration the permitted transaction. Additionally, if excess availability
under the agreement is less than $50 million, WESCO must maintain a fixed charge
coverage ratio of 1.1 to 1.0. At December 31, 2002, amounts available under the
agreement were approximately $153.9 million and WESCO was in compliance with all
covenants of the new facility.

WESCO has entered into a $51 million mortgage financing facility, $13
million of which was outstanding as of December 31, 2002. Total borrowings under
the mortgage financing are subject to a 22-year amortization schedule with a
balloon payment due at the end of the 10-year term. This mortgage financing
facility provides additional liquidity and financial flexibility for WESCO as
well as locks in fixed interest rates for longer-term capital. Proceeds from the
borrowings were used to reduce outstanding borrowings under WESCO's 2002
Revolving Credit Facility.

===== ===== =====


2002 Compared to 2001

Net Sales. Net sales for 2002 decreased by approximately $330 million, or
9.1%, to $3.3 billion compared with $3.7 billion in the prior year. The
continuing weakness in the North American economy has adversely affected the
major industrial and MRO markets where WESCO participates.

Gross Profit. Gross profit in 2002 decreased by $52.7 million, or 8.2%, to
$590.8 million from $643.5 million in the prior year due principally to the
decline in net sales. Gross profit margin was 17.8% in 2002 compared with 17.6%
in 2001. Billing margin improvements of 30 basis points over 2001 and a lower
level of provision for slow moving and obsolete inventory, were partially offset
by lower levels of supplier rebates and cash discounts that resulted from lower
purchasing activity and working capital improvements.

Selling, General and Administrative Expenses ("SG&A"). SG&A expenses
decreased by $22.8 million, or 4.4%, to $494.4 million. The decrease is
primarily due to compensation and benefit program expense reductions in the
current period. Employee headcount has been reduced by 4.4% since December 2001.
Shipping and handling expense included in SG&A was $37.2 million in 2002
compared with $38.2 million in 2001. Bad debt expense was $9.0 million for 2002
compared to $10.3 million for 2001. The improvement in 2002 results primarily
from reducing exposure to troubled accounts and industries through more
stringent credit policies. SG&A expense expressed as a percentage of sales was
14.9% for 2002 compared with 14.1% in 2001. The increase in SG&A expense as a
percentage of sales resulted from lower net sales in 2002.

Depreciation and Amortization. Depreciation and amortization decreased
$11.2 million to $19.8 million in 2002 reflecting WESCO's adoption of SFAS No.
142. WESCO recorded goodwill amortization expense of $11.9 million in 2001.

Income from Operations. Income from operations decreased $18.7 million to
$76.6 million in 2002, compared with $95.3 million in 2001. The decrease in
operating income is principally attributable to lower gross profit caused by the
decline in sales, partially offset by the decrease in SG&A expenses and
discontinuing amortization of goodwill.

Interest and Other Expenses. Interest expense totaled $43.0 million for
2002, a decrease of $2.1 million from 2001. The decrease in interest expense
results primarily from a lower level of average debt as well as lower net
interest rates including the full year impact in 2002 of WESCO's interest rate
swap agreement. Loss on debt extinguishment of $1.1 million represents non-cash
charges recognized upon the replacement of WESCO's previous revolving credit
agreement. Other expense totaled $6.6 million and $16.9 million in 2002 and
2001, respectively,


20


reflecting costs associated with the Receivables Facility. The $10.3 million
decrease was principally due to a decrease in the program's advance rates and a
lower average level of securitized accounts receivable.

Income Taxes. Income tax expense totaled $2.8 million in 2002, a decrease
of $10.3 million from 2001. The effective tax rates for 2002 and 2001 were 11.0%
and 39.4%, respectively. The decrease in the rate in 2002 is principally related
to the reversal of income tax contingency accruals of $5.3 million upon
acceptance by the IRS of tax returns filed through 1998 and the expected
favorable conclusion of the IRS examination for 1999, as well as a first quarter
income tax benefit of approximately $0.7 million related to the re-measurement
of deferred taxes related to the cumulative impact of a change in the expected
tax rate that will be applicable when these items reverse. The effective tax
rate, excluding the items described above was approximately 34.0% compared with
39.4% in 2001. The decrease in the effective rate is the result of the creation
of a foreign finance company and decreased amortization expense from the
adoption of SFAS No. 142.

Net Income. Net income and diluted earnings per share totaled $23.1
million and $0.49 per share, respectively, in 2002, compared with $20.2 million
and $0.43 per share, respectively, in 2001.

2001 Compared to 2000

Net Sales. Net sales for the year ended December 31, 2001, decreased by
$223.1 million, or 5.7%, to $3.7 billion compared with $3.9 billion in the prior
year. The decrease was due principally to sales declines attributable to core
business operations of 8.6%, partially offset by sales from acquired companies.

Gross Profit. Gross profit for the year ended December 31, 2001, decreased
by $40.6 million, or 5.9%, to $643.5 million from $684.1 million in the prior
year due principally to the decline in net sales. Gross profit margin was 17.6%
in both 2001 and 2000. Gross profit included other charges of $4.4 million in
2000 related to inventory write-downs. Excluding these charges, gross profit was
17.7% of sales in 2000. The decline in the gross profit percentage is due
principally to a decline in supplier rebates, partially offset by increased
billing margins.

Selling, General and Administrative Expenses ("SG&A"). SG&A expenses
decreased by $7.2 million, or 1.4%, to $517.2 million. The year 2000 includes
$7.0 million of other charges, related primarily to a deteriorating credit
environment and customer bankruptcies that continued at similar levels in 2001.
Core business SG&A expenses decreased $15.7 million or 3.1% from 2000, due
principally to decreased payroll costs as the Company reduced its headcount
throughout the year as it rebalanced its branch and headquarters staff to be in
line with developing economic activity. Additionally, incentive compensation
expense decreased in 2001 as sales and profitability declines reduced both
commission and bonus requirements. Shipping and handling expense included in
SG&A was $38.2 million in 2001 compared with $33.7 million in 2000. Bad debt
expense was $10.3 million for 2001 compared to $11.2 million for 2000. As a
percentage of sales, excluding the other charges, SG&A expenses increased to
14.1% in 2001 from 13.3% in 2000, reflecting the negative leverage of lower
sales volume.

Depreciation and Amortization. Depreciation and amortization increased
$6.0 million to $31.0 million in 2001, reflecting depreciation related to
increases in property, buildings and equipment over the prior year, higher
amortization of goodwill from acquisitions and higher amortization of software
costs.

Income from Operations. Income from operations decreased $30.1 million to
$95.3 million in 2001, compared with $125.4 million in 2000. Income from
operations in 2000 includes a restructuring charge of $9.4 million.
Approximately $8.0 million of the charge was inventory and investment write-offs
associated with management's decision to close branches and no longer pursue its
business strategy with an affiliate. The remaining $1.4 million in charges
related to other costs associated with the branch closures, including $1.0
million for lease termination payments and $0.4 million in severance payments.
Excluding the restructuring charge and the aforementioned other charges of $11.4
million, operating income decreased by $50.8 million, due principally to the
decline in gross profit and the increase in depreciation and amortization.

Interest and Other Expenses. Interest expense totaled $45.1 million for
2001, an increase of $1.4 million from 2000. The increase in interest expense
results primarily from an increase in average debt level compared to the
previous year somewhat offset by lower average interest rates. Other expense
totaled $16.9 million and $24.9


21


million in 2001 and 2000, respectively, reflecting costs associated with the
Receivables Facility. The $8.0 million decrease was principally due to a
decrease in the program's advance rates.

Income Taxes. Income tax expense totaled $13.1 million in 2001, a decrease
of $10.1 million from 2000. The effective tax rates for 2001 and 2000 were 39.4%
and 41.0%, respectively. The decrease in the rate in 2001 is principally related
to the effect of foreign tax credits on decreased pretax income as compared to
the prior year.

Net Income. Net income and diluted earnings per share totaled $20.2
million and $0.43 per share, respectively, in 2001, compared with $33.4 million
and $0.70 per share, respectively, in 2000.

LIQUIDITY AND CAPITAL RESOURCES

Total assets were approximately $1.0 billion at December 31, 2002, a
$142.8 million decrease from December 31, 2001. Stockholders' equity totaled
$169.3 million at December 31, 2002, compared with $144.7 million at December
31, 2001.

WESCO's liquidity needs arise from seasonal working capital requirements,
capital expenditures, acquisitions and debt service obligations. In addition,
certain of our acquisition agreements contain earn-out provisions based
principally on future earnings targets. The most significant of these agreements
relates to the acquisition of Bruckner Supply Company, which provides for an
earn-out potential of $80 million during any one of the next three years if
certain earnings targets are achieved. WESCO paid $10 million pursuant to this
agreement in April 2002. The maximum amount payable in any single year under
this agreement is $30 million. Certain other acquisitions also contain
contingent consideration provisions, only one of which could require a
significant payment. Management estimates this payment could range from $0 to
$20 million and would be made in 2008. To meet its funding requirements, WESCO
uses a mix of internally generated cash flow, its revolving credit facility, its
Receivables Facility and equity transactions.

acquisition. Acquisition-related earn-out payments, if required, will be based
on the performance of acquired companies.

Mortgage Financing Facility

WESCO has entered into a $51 million mortgage financing facility, $13
million of which was outstanding as of December 31, 2002. Total borrowings under
the mortgage financing are subject to a 22-year amortization schedule with a
balloon payment due at the end of the 10-year term. Proceeds from the borrowings
were used to reduce outstanding borrowings under the 2002 Revolving Credit
Facility.

2002 Revolving Credit Facility

In March 2002, WESCO Distribution, Inc. entered into a $290 million
revolving credit agreement that is collateralized by substantially all inventory
owned by WESCO and also by the accounts receivable of WESCO Canada. Availability
under the agreement, which matures in 2007, is limited to the amount of eligible
inventory and Canadian receivables applied against certain advance rates.
Proceeds from this agreement were used to retire WESCO Distribution Inc.'s
existing revolving credit facility. Interest on this facility is at LIBOR plus a
margin that will range between 2.0% to 2.75% depending upon the amount of excess
availability under the facility. As long as the average daily excess
availability for both the preceding and projected succeeding 90 day period is
greater than $50 million, then WESCO would be permitted to make acquisitions and
repurchase outstanding public stock and bonds. The above permitted transactions
would also be allowed if such excess availability is between $25 million and $50
million and WESCO's fixed charge coverage ratio, as defined by the agreement, is
at least 1.25 to 1.0 after taking into consideration the permitted transaction.
Additionally, if excess availability under the agreement is less than $50
million, then WESCO must maintain a fixed charge coverage ratio of 1.1 to 1.0.
At December 31, 2002 the interest rate was 4.0%. This facility also had various
restrictive covenants including financial ratios. WESCO


23


was in compliance with all such covenants as of December 31, 2002. At December
31, 2002, WESCO had approximately $154 million available under its 2002
Revolving Credit Facility compared to approximately $47 million available at
December 31, 2001.

Senior Notes

WESCO has $400 million in aggregate principal amount of senior
subordinated notes due 2008. The notes were issued with an average issue price
of 98%. The net proceeds received by the Company from the notes were
approximately $376 million.

Interest Rate Swap Agreements

During September and October of 2001, WESCO entered into four separate
fixed-to-floating interest rate swap agreements, each with a notional amount of
$25 million. These agreements have six-year terms expiring concurrently with the
9.13% senior subordinated notes with the intent of converting $100 million of
the senior subordinated notes from a fixed-to-floating rate facility. Pursuant
to these agreements, WESCO will receive fixed interest payments at the rate of
9.13% and will pay interest at three-month LIBOR plus a premium. The LIBOR rates
in the agreements are reset quarterly. In 2002, the agreements had the effect of
reducing the interest cost on $100 million of the senior notes from 9.13% to
6.00%. The agreements can be terminated by the counterparty in accordance with a
redemption schedule that is consistent with the redemption schedule for the
senior subordinated notes.

WESCO entered into interest rate swap agreements as a means to hedge its
interest rate exposure and maintain certain amounts of variable rate and fixed
rate debt. Since the swaps have been designated as hedging instruments, their
fair values are reflected in the Company's Consolidated Balance Sheets. Net
amounts to be received or paid under the swap agreements are reflected as
adjustments to interest expense.

Accounts Receivable Securitization Program

WESCO maintains a Receivables Facility with a group of financial
institutions with a purchase commitment up to $396 million. Under the
Receivables Facility, which is subject to an annual renewal in June 2003, WESCO
sells, on a continuous basis, to WESCO Receivables Corporation, a wholly-owned
SPC, an undivided interest in all domestic accounts receivable. The SPC sells
without recourse to a third-party conduit, all the eligible receivables while
maintaining a subordinated interest, in the form of overcollateralization, in a
portion of the receivables. WESCO has agreed to continue servicing the sold
receivables for the financial institution at market rates; accordingly, no
servicing asset or liability has been recorded. See Note 6 to the Consolidated
Financial Statements.

Cash Flow

An analysis of cash flows for 2002 and 2001 follows:

Operating Activities. Cash provided by operating activities totaled $20.4
million for the year ended December 31, 2002, compared to $161.1 million a year
ago. Cash provided by operations in 2002 and 2001 included $37.0 million and
$45.0 million, respectively, of net cash outflows related to WESCO's Receivables
Facility. Excluding these transactions, operating activities provided $57.4
million in 2002 and $206.1 million in 2001. On this basis, the year-to-year
decrease in operating cash flow of $148.7 million was primarily due to a
decrease of accounts payable.

Investing Activities. Net cash used in investing activities was $23.1
million in 2002, compared to $69.2 million in 2001. Cash used for investing
activities was higher in 2001 due to $41.8 million more in acquisition payments
and $4.5 million more in capital expenditures. Capital expenditures in 2002 were
$9.3 million compared to $13.8 million in 2001 and were for computer equipment
and software, and branch and distribution center facility improvements.

Financing Activities. Cash used by financing activities in 2002 was $49.9
million primarily for net debt repayments and costs associated with the issuance
of debt. Cash used by financing activities was $38.0 million in 2001 that was
primarily due to net debt repayments of $37.2 million.

Contractual Cash Obligations and Other Commercial Commitments

The following summarizes WESCO's contractual obligations at December 31,
2002, and the effect such obligations are expected to have on its liquidity and
cash flow in future periods.

Management believes that cash generated from operations, together with
amounts available under the credit agreement and the Receivables Facility, will
be sufficient to meet WESCO's working capital, capital expenditures and other
cash requirements for the foreseeable future. There can be no assurance,
however, that this will be or will continue to be the case.

INFLATION

The rate of inflation, as measured by changes in the consumer price index,
did not have a material effect on the sales or operating results of the Company
during the periods presented. However, inflation in the future could affect the
Company's operating costs. Price changes from suppliers have historically been
consistent with inflation and have not had a material impact on the Company's
results of operations.

SEASONALITY

The Company's operating results are affected by certain seasonal factors.
Sales are typically at their lowest during the first quarter due to a reduced
level of activity during the winter months. Sales increase during the warmer
months beginning in March and continuing through November. Sales drop again
slightly in December as the weather cools and also as a result of a reduced
level of activity during the holiday season. As a result, the Company reports
sales and earnings in the first quarter that are generally lower than that of
the remaining quarters.


25


IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities." SFAS No. 146 nullifies Emerging
Issues Task Force (EITF) Issue No. 94-3, "Liability Recognition for Certain
Employee Termination Benefits and Other Costs to Exit an Activity," under which
a liability for an exit cost was recognized at the date of an entity's
commitment to an exit plan. SFAS No. 146 requires that a liability for a cost
associated with an exit or disposal activity be recognized at fair value when
the liability is incurred. The provisions of this statement are effective for
exit or disposal activities that are initiated after December 31, 2002. The
Company does not believe that the adoption of this statement will have a
material impact on its financial statements.

In December 2002, the FASB issued SFAS No. 148, "Accounting for
Stock-Based Compensation -- Transition and Disclosure -- an amendment of SFAS
No. 123." SFAS No. 148 was issued to provide alternative methods of transition
for a voluntary change to the fair-value-based method of accounting for
stock-based employee compensation. In addition, this statement amends the
disclosure requirements of SFAS No. 123 to require prominent disclosures in both
annual and interim financial statements about the method of accounting for
stock-based employee compensation and the effect of the method used on reported
results. The amendments to SFAS No. 123 in paragraphs 2(a)-2(e) of this
statement shall be effective for financial statements for fiscal years ending
after December 15, 2002. Currently, WESCO is evaluating the impact of adopting
the fair-value-based method of accounting for stock-based compensation under
SFAS No. 148.

In November 2002, the FASB issued Interpretation No. 45, "Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Others," which elaborates on the disclosures to be
made by a guarantor in its interim and annual financial statements about its
obligations under certain guarantees that it has issued. It also clarifies that
a guarantor is required to recognize, at the inception of a guarantee, a
liability for the fair value of the obligation undertaken in issuing the
guarantee. This interpretation does not prescribe a specific approach for
subsequently measuring the guarantor's recognized liability over the term of the
related guarantee. This interpretation also incorporates, without change, the
guidance in FASB Interpretation No. 34, "Disclosure of Indirect Guarantees of
Indebtedness of Others," which is being superseded. The initial recognition and
initial measurement provisions of this interpretation are applicable on a
prospective basis to guarantees issued or modified after December 31, 2002 and
the disclosure requirements in this interpretation are effective for financial
statements of interim or annual periods ending after December 15, 2002. WESCO
includes the required disclosure of this interpretation in Notes 10 and 18 to
the Consolidated Financial Statements.

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities." This interpretation requires unconsolidated
variable interest entities to be consolidated by their primary beneficiaries if
the entities do not effectively disperse the risk and rewards of ownership among
their owners and other parties involved. The provisions of this interpretation
are effective immediately to all variable interest entities created after
January 1, 2003 and variable interest entities in which an enterprise obtains an
interest in after that date. For variable interest entities created before this
date, the provisions are effective July 31, 2003. WESCO is currently evaluating
the potential impact of this interpretation on its consolidated financial
statements, however, WESCO does not believe it will affect the accounting
treatment for its Receivables Facility.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS.

FOREIGN CURRENCY RISKS

Over 90% of WESCO's sales are denominated in U. S. dollars and are
primarily from customers in the United States. As a result, currency
fluctuations are currently not material to WESCO's operating results. WESCO does
have foreign subsidiaries located in North America, Europe and Asia and may
establish additional foreign subsidiaries in the future. Accordingly, WESCO may
derive a more significant portion of its sales from international operations and
a portion of these sales may be denominated in foreign currencies. As a result,
WESCO's future operating results could become subject to fluctuations in the
exchange rates of those currencies in relation to the U. S. dollar. Furthermore,
to the extent that WESCO engages in international sales denominated in U. S.
dollars, an increase in the value of the U. S. dollar relative to foreign
currencies could make WESCO's products


26


less competitive in international markets. WESCO has and will continue to
monitor its exposure to currency fluctuations.

INTEREST RATE RISKS

WESCO's indebtedness as of December 31, 2002 is comprised of $10.0 million
of variable-rate borrowings outstanding under its revolving credit facility and
$408.0 million of fixed-rate borrowings. Interest cost under the revolving
credit facility is based on various indices plus a borrowing margin.

In September and October of 2001, WESCO entered into several
fixed-to-floating interest rate swap agreements with an aggregate notional
amount of $100 million. Under the terms of these agreements, WESCO pays interest
on the notional amount of the swap at LIBOR plus a premium and receives fixed
payments at the rate of 9 1/8%. The LIBOR rates in the agreements are reset
quarterly. At December 31, 2002, the net fair value of interest-rate-related
derivatives designated as fair value hedges of debt resulted in an increase of
$5.1 million. These interest rate swap agreements reduced interest expense by
approximately $3.1 million in 2002. The agreements can be terminated under
certain conditions. There is no assurance WESCO could find comparable interest
rate swap agreements to continue to reduce interest expense at current levels.

At December 31, 2002, WESCO had approximately $110.0 million of variable
rate debt, which includes the effect of $100 million in interest rate swaps. A
hypothetical 10% change in interest rates based on these variable-rate borrowing
levels would result in a $0.6 million increase or decrease in interest expense.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and Board of Directors
of WESCO International, Inc.:

In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, stockholders' equity and cash
flows present fairly, in all material respects, the financial position of WESCO
International, Inc. and its subsidiaries (collectively, "WESCO") at December 31,
2002 and 2001, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 2002, in conformity with
accounting principles generally accepted in the United States of America. These
financial statements are the responsibility of WESCO's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
auditing standards generally accepted in the United States of America, which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

As discussed in Note 4 to the Consolidated Financial Statements, WESCO
adopted Statement of Financial Accounting Standards No. 142, "Goodwill and Other
Intangible Assets." Accordingly, WESCO changed its method of accounting for
goodwill in 2002.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

WESCO International, Inc. and its subsidiaries (collectively, "WESCO"),
headquartered in Pittsburgh, Pennsylvania, is a full-line distributor of
electrical supplies and equipment and is a provider of integrated supply
procurement services. WESCO currently operates over 350 branch locations and
five distribution centers in the United States, Canada, Mexico, Puerto Rico,
Guam, the United Kingdom, Nigeria and Singapore.

On June 5, 1998, WESCO repurchased and retired all of the common stock of
WESCO principally held by non-management shareholders for $10.75 per share for
net consideration of approximately $653.5 million. In addition, WESCO repaid
approximately $379.1 million of then outstanding indebtedness, and sold
29,604,351 shares of common stock to an investor group led by affiliates of the
Cypress Group LLC ("Cypress") representing approximately 88.7% of WESCO at that
time for an aggregate cash consideration of $318.1 million. Existing management
retained approximately an 11.3% interest in WESCO immediately following the
transaction. WESCO funded the equity consideration and the repayment of
indebtedness from proceeds of the cash equity contribution, issuance of
approximately $351 million of senior subordinated and senior discount notes, a
$170 million credit facility and the sale of approximately $250 million of
accounts receivable. Given the 11.3% retained ownership, the transaction was
treated as a recapitalization for financial reporting purposes and, accordingly,
the historical bases of WESCO's assets and liabilities were not affected.

2. ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements include the accounts of WESCO
International, Inc. and all of its subsidiaries. All significant intercompany
accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with generally
accepted accounting principles in the United States of America requires
management to make estimates and assumptions that affect the amounts reported in
the consolidated financial statements and accompanying disclosures. Although
these estimates are based on management's best knowledge of current events and
actions WESCO may undertake in the future, actual results may ultimately differ
from the estimates.

Revenue Recognition

Revenues are recognized when title, ownership and risk of loss pass to the
customer, or services are rendered. In nearly all cases, this occurs at the time
of shipment from our distribution point, as the terms of virtually all of
WESCO's sales are FOB shipping point.

Supplier Volume Rebates

WESCO receives rebates from certain suppliers based on contractual
arrangements with such suppliers. An asset on the balance sheet represents the
estimated amounts due to WESCO under the rebate provisions of such contracts.
The corresponding rebate income is recorded as a reduction of cost of goods
sold. The appropriate level of such income is derived from the level of actual
purchases being made by WESCO from suppliers, in accordance with the provisions
of Emerging Issues Task Force ("EITF") Issue No. 02-16, "Accounting by a
Reseller for Cash Consideration Received from a Vendor."

Shipping and Handling Costs and Fees

WESCO records the majority of costs and fees associated with transporting
its products to customers as a component of selling, general and administrative
expenses. These costs totaled $37.2 million, $38.2 million and $33.7 million in
2002, 2001 and 2000, respectively.


34


The remaining shipping and handling costs relate to costs that are billed
to our customers. These costs and the related revenue are included in net sales
in the consolidated statement of operations.

Cash Equivalents

Cash equivalents are defined as highly liquid investments with original
maturities of 90 days or less when purchased.

Asset Securitization

WESCO accounts for the securitization of accounts receivable in accordance
with Statement of Financial Accounting Standards ("SFAS") No. 140, "Accounting
for Transfers and Servicing of Financial Assets and Extinguishments of
Liabilities." At the time the receivables are sold the balances are removed from
the balance sheet. SFAS No. 140 also requires retained interests in the
transferred assets to be measured by allocating the previous carrying amount
between the assets sold and retained interests based on their relative fair
values at the date of transfer. The Company estimates fair value based on the
present value of expected future cash flows discounted at a rate commensurate
with the risks involved.

Allowance for Doubtful Accounts

WESCO maintains allowances for doubtful accounts for estimated losses
resulting from the inability of its customers to make required payments. WESCO
has a systematic procedure using estimates based on historical data and
reasonable assumptions of collectibility made at the local branch level and at
the consolidated corporate basis to calculate the allowance for doubtful
accounts. If the financial condition of WESCO's customers were to deteriorate,
resulting in an impairment of their ability to make payments, additional
allowances may be required. The allowance for doubtful accounts was $10.3
million at December 31, 2002 and $11.8 million at December 31, 2001.

Inventories

Inventories primarily consist of merchandise purchased for resale and are
stated at the lower of cost or market. Cost is determined principally under the
average cost method. The Company makes provisions for obsolete or slow-moving
inventories as necessary to properly reflect inventory value. Reserves for
excess and obsolete inventories were $11.9 million and $16.8 million at December
31, 2002 and 2001, respectively.

Property, Buildings and Equipment

Property, buildings and equipment are recorded at cost. Depreciation
expense is determined using the straight-line method over the estimated useful
lives of the assets. Leasehold improvements are amortized over either their
respective lease terms or their estimated lives, whichever is shorter. Estimated
useful lives range from five to forty years for buildings and leasehold
improvements, three to seven years for furniture, fixtures and equipment and two
to five years for software costs.

Expenditures for new facilities and improvements that extend the useful
life of an asset are capitalized. Ordinary repairs and maintenance are expensed
as incurred. When property is retired or otherwise disposed of, the cost and the
related accumulated depreciation are removed from the accounts and any related
gains or losses are recorded.

Goodwill

Prior to the adoption of SFAS No. 142 discussed in Note 4, goodwill
arising from acquisitions was amortized on a straight-line basis over periods
ranging from 25 to 35 years. The carrying value of goodwill was regularly
reviewed by evaluating the estimated future undiscounted cash flows to determine
recoverability of the assets.

Intangible Assets

WESCO's intangible assets consist primarily of non-compete agreements with
contractually determined lives. The carrying value of these intangible assets
were $3.2 million and $3.6 million at December 31, 2002 and 2001, respectively
and are regularly reviewed by evaluating the estimated future undiscounted cash
flows to determine recoverability of the assets. Any decrease in value is
recognized on a current basis.


35


Income Taxes

Income taxes are accounted for under the liability method. Deferred tax
assets and liabilities are determined based on differences between the financial
reporting and tax basis of assets and liabilities and are measured using the
enacted tax rates and laws that will be in effect when the differences are
expected to reverse. Valuation allowances, if any, are provided when a portion
or all of a deferred tax asset may not be realized.

Foreign Currency Translation

The local currency is the functional currency for all of WESCO's
operations outside the United States. Assets and liabilities of these operations
are translated to U.S. dollars at the exchange rate in effect at the end of each
period. Income statement accounts are translated at the average exchange rate
prevailing during the period. Translation adjustments arising from the use of
differing exchange rates from period to period are included as a component of
stockholders' equity. Gains and losses from foreign currency transactions are
included in net income for the period.

Treasury Stock

Common stock purchased for treasury is recorded at cost. At the date of
subsequent reissue, the treasury stock account is reduced by the cost of such
stock on the weighted average cost basis.

Stock Options

WESCO accounts for stock-based compensation arrangements under the
recognition and measurement principles of APB Opinion No. 25, "Accounting for
Stock Issued to Employees," ("APB 25") and related interpretations. WESCO
currently records compensation expense for its stock options utilizing the
intrinsic value method in accordance with APB 25. No stock-based employee
compensation cost has been reflected in net income, as all options granted in
the years ended December 31, 2002, 2001 and 2000 had an exercise price equal to
the market value of the underlying common stock on the date of grant. The
following table illustrates the effect on net income and earnings per share if
WESCO had applied the fair value recognition provisions of SFAS No. 123,
"Accounting for Stock-Based Compensation," to measure stock-based compensation:



YEAR ENDED DECEMBER 31

(IN THOUSANDS)

Diluted as reported ......................... $ 0.49 $ 0.43 $ 0.70

The weighted average fair value per option granted was $4.57, $2.99 and
$4.82 for the years ended December 31, 2002, 2001 and 2000, respectively.


36


For purposes of presenting pro forma results, the fair value of each
option grant is estimated on the date of grant using the Black-Scholes option
pricing model and the following assumptions:



YEAR ENDED DECEMBER 31
----------------------------
2002 2001 2000
---- ---- ----

Risk-free interest rate .................... 3.4% 4.9% 6.0%
Expected life (years) ...................... 6.0 6.0 6.0
Stock price volatility ..................... 75.0% 65.0% 45.0%
Employee turnover .......................... 5.0% 5.0% 5.0%


Fair Value of Financial Instruments

For certain of WESCO's financial instruments, including cash and cash
equivalents, accounts receivable, notes payable and variable-rate borrowings,
accounts payable and other accrued liabilities, the carrying values approximate
fair value due to their short maturities. WESCO's $400 million senior
subordinated notes were issued at an average discount of 2.1% and were trading
at a discount of 20% at December 31, 2002.

Interest Rate Swaps

WESCO enters into interest rate swap agreements to reduce the exposure of
its debt to interest rate risk and formally documents this strategy as part of
its risk management program. Interest rate swaps are used to modify the market
risk exposures for a portion of WESCO's debt to achieve LIBOR-based floating
interest expense. The swap transactions generally involve the exchange of
fixed-for-floating interest payment obligations and are accounted for as fair
value hedges. The gain or loss on the derivative instrument, as well as the
offsetting gain or loss on the hedged item, is recognized in earnings in the
current period.

WESCO estimates the fair value of derivatives based on quoted market
prices or pricing models using current market rates, and records all derivatives
on the balance sheet at fair value. At December 31, 2002, the fair value of
interest-rate-related derivatives designated as fair value hedges of debt was
$5.1 million and is recorded in non-current assets. Cash flows from derivative
instruments are presented in a manner consistent with the underlying
transaction.

Environmental Expenditures

WESCO has facilities and operations that distribute certain products that
must comply with environmental regulations and laws. Expenditures for current
operations are expensed or capitalized, as appropriate. Expenditures relating to
existing conditions caused by past operations, and which do not contribute to
future revenue, are expensed. Liabilities are recorded when remedial efforts are
probable and the costs can be reasonably estimated.

Reclassifications

Certain prior period amounts have been reclassified to conform with the
current year presentation.

Recent Accounting Pronouncements

In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities." SFAS No. 146 nullifies EITF Issue
No. 94-3, "Liability Recognition for Certain Employee Termination Benefits and
Other Costs to Exit an Activity," under which a liability for an exit cost was
recognized at the date of an entity's commitment to an exit plan. SFAS No. 146
requires that a liability for a cost associated with an exit or disposal
activity be recognized at fair value when the liability is incurred. The
provisions of this statement are effective for exit or disposal activities that
are initiated after December 31, 2002. WESCO does not believe that the adoption
of this statement will have a material impact on its financial statements.

In December 2002, the FASB issued SFAS No. 148, "Accounting for
Stock-Based Compensation -- Transition and Disclosure -- an amendment of SFAS
No. 123." SFAS No. 148 was issued to provide alternative methods of transition
for a voluntary change to the fair-value-based method of accounting for
stock-based employee compensation. In addition, this statement amends the
disclosure requirements of SFAS No. 123 to require prominent disclosures in both
annual and interim financial statements about the method of accounting for
stock-based


37


employee compensation and the effect of the method used on reported results. The
amendments to SFAS No. 123 in paragraphs 2(a)-2(e) of this statement shall be
effective for financial statements for fiscal years ending after December 15,
2002. Currently, WESCO is evaluating the impact of adopting the fair-value-based
method of accounting for stock-based compensation under SFAS No. 148.

In November 2002, the FASB issued Interpretation No. 45, "Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Others," which elaborates on the disclosures to be
made by a guarantor in its interim and annual financial statements about its
obligations under certain guarantees that it has issued. It also clarifies that
a guarantor is required to recognize, at the inception of a guarantee, a
liability for the fair value of the obligation undertaken in issuing the
guarantee. This interpretation does not prescribe a specific approach for
subsequently measuring the guarantor's recognized liability over the term of the
related guarantee. This interpretation also incorporates, without change, the
guidance in FASB Interpretation No. 34, "Disclosure of Indirect Guarantees of
Indebtedness of Others," which is being superseded. The initial recognition and
initial measurement provisions of this interpretation are applicable on a
prospective basis to guarantees issued or modified after December 31, 2002 and
the disclosure requirements in this interpretation are effective for financial
statements of interim or annual periods ending after December 15, 2002. WESCO
includes the required disclosure of this interpretation in Notes 10 and 18 to
the Consolidated Financial Statements.

In January 2003, the FASB issued Interpretation No. 46, "Consolidation of
Variable Interest Entities." This interpretation requires unconsolidated
variable interest entities to be consolidated by their primary beneficiaries if
the entities do not effectively disperse the risk and rewards of ownership among
their owners and other parties involved. The provisions of this interpretation
are effective immediately to all variable interest entities created after
January 1, 2003 and variable interest entities in which an enterprise obtains an
interest in after that date. For variable interest entities created before this
date, the provisions are effective July 31, 2003. WESCO is currently evaluating
the potential impact of this interpretation on its consolidated financial
statements, however, WESCO does not believe it will affect the accounting
treatment for its Receivables Facility.

3. INITIAL PUBLIC OFFERING

On May 17, 1999, WESCO completed its initial public offering of 11,183,750
shares of common stock ("Offering") at $18.00 per share. In connection with the
Offering, certain employee rights to require WESCO to repurchase outstanding
redeemable common stock were terminated and approximately $31.5 million of
convertible notes were converted into 1,747,228 shares of common stock. Proceeds
from the Offering (after deducting Offering costs of $14.5 million) totaling
$186.8 million and borrowings of approximately $65 million were used to redeem
all of the 11 1/8% senior discount notes ($62.8 million) and to repay the
existing revolving credit and term loan facilities ($188.8 million).

In connection with the Offering, the Board of Directors approved a 57.8 to
one stock split effected in the form of a stock dividend of WESCO's common
stock. The Board of Directors also reclassified the Class A common stock into
common stock, increased the authorized common stock to 210,000,000 shares and
the authorized Class B common stock to 20,000,000 shares and authorized
20,000,000 shares of $.01 par value preferred stock, all effective May 11, 1999.
In this report, all share and per share data have been restated to reflect the
stock split.

4. GOODWILL

Effective January 1, 2002, WESCO adopted SFAS No. 141, "Business
Combinations" and SFAS No. 142, "Goodwill and Other Intangible Assets." Under
SFAS No. 141, all business combinations are accounted for under the purchase
method. Under SFAS No. 142, goodwill is no longer amortized, but will be reduced
if it is found to be impaired. Goodwill is tested for impairment annually or
more frequently when events or circumstances occur indicating that goodwill
might be impaired. During 2002, WESCO completed its transitional and annual
impairment reviews required by SFAS No. 142. Each of WESCO's seven reporting
units was tested for impairment by comparing the implied fair value of each
reporting unit with its carrying value using discounted cash flow analyses.
Considerable management judgment is necessary to estimate discounted future cash
flows. Assumptions used for these estimated cash flows were based on a
combination of historical results and current internal forecasts. No impairment
losses were identified as a result of these reviews.

The changes in the carrying amount of goodwill for the year ended December
31, 2002 are as follows (in thousands):



Balance as of January 1, 2002 ............. $311,073
Goodwill additions during year ............ 3,005

In conformity with SFAS No. 142, the results of prior periods have not
been restated. The following is a reconciliation of the impact of not amortizing
goodwill on prior periods of WESCO's net income and earnings per share for the
years December 31, 2002, 2001 and 2000.

5. RESTRUCTURING CHARGE

In the fourth quarter of 2000, WESCO commenced certain programs to reduce
costs, improve productivity and exit certain operations. Total costs under these
programs were $9.4 million, and were comprised of $5.4 million related to the
closure of fourteen branch operations in the United States, Canada and the
Balkans, and $4.0 million related to the non-cash write-down of an investment in
an affiliate. The $5.4 million charge related to the closure of fourteen branch
operations is principally comprised of an inventory write-down of approximately
$4.0 million and lease termination costs of approximately $1.0 million, of which
$0.7 million was paid through December 31, 2002. The $4.0 million investment
write-down was a result of management's decision to no longer pursue its
business strategy with an affiliate.

6. ACCOUNTS RECEIVABLE SECURITIZATION

WESCO maintains an accounts receivable securitization program
("Receivables Facility") that requires an annual renewal of its terms. Under the
Receivables Facility, WESCO sells, on a continuous basis, to WESCO Receivables
Corporation, a wholly-owned, special purpose company ("SPC"), an undivided
interest in all domestic accounts receivable. The SPC sells without recourse to
a third-party conduit all the eligible receivables while maintaining a
subordinated interest, in the form of overcollateralization, in a portion of the
receivables. WESCO has agreed to continue servicing the sold receivables for the
financial institution at market rates; accordingly, no servicing asset or
liability has been recorded.

As of December 31, 2002 and 2001, securitized accounts receivable totaled
approximately $346 million and $395 million, respectively, of which the
subordinated retained interest was approximately $53 million and $65 million,
respectively. Accordingly, approximately $293 million and $330 million of
accounts receivable balances were removed from the consolidated balance sheets
at December 31, 2002 and 2001, respectively. WESCO reduced its Receivables
Facility by $37.0 million in 2002 and by $45.0 million in 2001. Costs associated
with the Receivables Facility totaled $6.6 million, $16.9 million and $24.9
million in 2002, 2001 and 2000, respectively. These amounts are recorded as
other expenses in the consolidated statements of operations and are primarily
related to the discount and loss on the sale of accounts receivables, partially
offset by related servicing revenue.


39


The key economic assumptions used to measure the retained interest at the
date of the securitization for securitizations completed in 2002 were a discount
rate of 3% and an estimated life of 1.5 months. At December 31, 2002, an
immediate adverse change in the discount rate or estimated life of 10% and 20%
would result in a reduction in the fair value of the retained interest of $0.3
million and $0.4 million, respectively. These sensitivities are hypothetical and
should be used with caution. As the figures indicate, changes in fair value
based on a 10% variation in assumptions generally cannot be extrapolated because
the relationship of the change in assumption to the change in fair value may not
be linear. Also, in this example, the effect of a variation in a particular
assumption on the fair value of the retained interest is calculated without
changing any other assumption. In reality, changes in one factor may result in
changes in another.

7. ACQUISITIONS

In 2001, WESCO acquired a distributor serving contractors who install gas,
lighting and communication utility infrastructure. In 2000, WESCO acquired three
electrical distributors. Total goodwill recorded as a result of these
acquisitions was approximately $47 million and $38 million for the years ended
December 31, 2001 and 2000, respectively. Certain of these acquisitions also
contain contingent consideration provisions that are not material to the
consolidated financial statements of WESCO. A summary of certain information
with respect to all acquisitions follows:

======== ======== ========


All of the acquisitions were accounted for under the purchase method of
accounting for business combinations. The results of operations of these
companies are included in the consolidated financial statements prospectively
from the acquisition dates. Pro forma results of these acquisitions, assuming
they had been made at the beginning of each year presented, would not be
materially different from the consolidated results reported herein.

In 1998, WESCO acquired substantially all the assets and assumed
substantially all liabilities and obligations relating to the operations of
Bruckner Supply Company, Inc. ("Bruckner"). Under the terms of the purchase
agreement, additional contingent consideration, if any, is to be paid based on a
multiple of increases in earnings before interest, taxes, depreciation and
amortization of Bruckner through 2004. Up to 50% of the additional future
contingent consideration, if any, may be converted at the election of the holder
into common stock at the then market value. The purchase agreement provides for
an additional earn-out potential of $80 million during any one of the next three
years if certain earning targets are achieved. WESCO paid, including interest,
$10 million pursuant to this agreement in 2002. The maximum amount payable in
any single year under this agreement is $30 million. Certain other acquisitions
also contain contingent consideration provisions, only one of which could
require a significant payment. Management estimates this payment could range
from $0 to $20 million and would be made in 2008.

8. CONCENTRATIONS OF CREDIT RISK AND SIGNIFICANT SUPPLIERS

WESCO distributes its products and services and extends credit to a large
number of customers in the industrial, construction, utility and manufactured
structures markets. In addition, one supplier accounted for approximately 13%,
14% and 13% of WESCO's purchases for each of the three years, 2002, 2001 and
2000, respectively.

respectively.

1999 Revolving Credit Facility

In June 1999, WESCO Distribution, Inc., a wholly-owned subsidiary of
WESCO, entered into a $400 million revolving credit facility with certain
financial institutions ("1999 Revolving Credit Facility"). The 1999 Revolving
Credit Facility consisted of up to $365 million of revolving loans denominated
in U.S. dollars and a Canadian sublimit totaling US$35 million. Borrowings under
the 1999 Revolving Credit Facility were collateralized by substantially all the
assets of WESCO Distribution, Inc. other than real property and accounts
receivable sold under the Receivables Facility, and are guaranteed by WESCO
International, Inc. and certain subsidiaries. In August 2001, WESCO
Distribution, Inc. entered into an amendment to the 1999 Revolving Credit
Facility, which among other things, affected the pricing and amounts available
under the 1999 Revolving Credit Facility. At December 31, 2001, the average
interest rate on borrowings under this facility was 6.0%.

In March 2002, the 1999 Revolving Credit Facility was terminated. In
conjunction with the termination, WESCO wrote off debt issuance costs of
approximately $1.1 million. In accordance with SFAS No. 145 this amount has not
been treated as an extraordinary item.


41


2002 Revolving Credit Facility

In March 2002, WESCO Distribution, Inc. entered into a $290 million
revolving credit agreement ("2002 Revolving Credit Facility") that is
collateralized by substantially all inventory owned by WESCO and also by the
accounts receivable of WESCO Distribution Canada, Inc. Availability under the
agreement, which matures in 2007, is limited to the amount of eligible inventory
and Canadian receivables applied against certain advance rates. Proceeds from
this agreement were used to retire WESCO Distribution, Inc.'s 1999 Revolving
Credit Facility. Interest on the 2002 Revolving Credit Facility is at LIBOR plus
a margin that will range between 2.0% to 2.75% depending upon the amount of
excess availability under the facility. As long as the average daily excess
availability for both the preceding and projected succeeding 90 day period is
greater than $50 million, WESCO would be permitted to make acquisitions and
repurchase outstanding public stock and bonds.

The above permitted transactions would also be allowed if such excess
availability is between $25 million and $50 million and WESCO's fixed charge
coverage ratio, as defined by the agreement, is at least 1.25 to 1.0 after
taking into consideration the permitted transaction. Additionally, if WESCO's
excess availability under the agreement is less than $50 million, WESCO must
maintain a fixed charge coverage ratio of 1.1 to 1.0.

At December 31, 2002, the average interest rate on borrowings under this
facility was 4.0%.

Mortgage Financing Facility

WESCO has entered into a $51 million mortgage financing facility, $13
million of which was outstanding as of December 31, 2002. Total borrowings under
the mortgage financing are subject to a 22-year amortization schedule with a
balloon payment due at the end of the 10-year term. Proceeds from the borrowings
were used to reduce outstanding borrowings under the 2002 Revolving Credit
Facility. Interest rates on borrowings under this facility are fixed at 6.5%.

Senior Subordinated Notes

In June 1998 and August 2001, WESCO Distribution Inc. completed an
offering of $300 million and $100 million, respectively, in aggregate principal
amount of 9 1/8% senior subordinated notes due on June 1, 2008. The notes were
issued at an average issue price of 98% of par. The net proceeds received from
the notes were approximately $376 million. The net proceeds were used to repay
outstanding indebtedness.

The senior subordinated notes in an aggregate principal amount of $400
million are fully and unconditionally guaranteed by WESCO International, Inc.

The senior subordinated notes bear interest at a stated rate of 9 1/8%
payable semiannually on June 1 and December 1 through June 1, 2008. The
effective interest rate for the senior subordinated notes is 9.5%.

The senior subordinated notes are redeemable at the option of WESCO
Distribution, Inc. in whole or in part, at any time after June 1, 2003 at the
following prices:



Redemption Price
----------------

2003 .................................................. 104.563%
2004 .................................................. 103.042
2005 .................................................. 101.521
2006 and thereafter ................................... 100.000


At any time prior to June 1, 2003, the senior subordinated notes may be
redeemed, in whole but not in part, at the option of WESCO Distribution, Inc. at
any time within 180 days after a change of control, at a redemption price equal
to the principal amount thereof plus accrued and unpaid interest and the then
applicable premium. In addition, the noteholders have the right to require WESCO
Distribution, Inc., upon a change of control, to repurchase all or any part of
the senior subordinated notes at a redemption price equal to 101% of the
principal amount provided plus accrued and unpaid interest.

In September and October 2001, WESCO entered into certain interest rate
swap agreements with respect to $100 million notional amount of indebtedness.
Pursuant to the agreements, WESCO will receive semi-annual fixed


42


interest payments at the rate of 9 1/8% commencing December 1, 2001 and will
make quarterly variable interest rate payments at rates based on LIBOR plus a
margin commencing December 1, 2001 (currently rates range from 5.40% to 5.59%).
The agreements can be terminated by the counterparty in accordance with a
redemption schedule that is consistent with the redemption schedule for the
senior subordinated notes.

Other

At December 31, 2002 and 2001, other borrowings primarily consisted of
notes issued to sellers in connection with acquisitions.

The following table sets forth the aggregate principal repayment requirements
for all indebtedness for the next five years and thereafter (in thousands):



2003 .................................................. $ 5,778
2004 .................................................. 315
2005 .................................................. 336
2006 .................................................. 334
2007 .................................................. 10,350
Thereafter ............................................ 411,824


WESCO's credit agreements contain various restrictive covenants that,
among other things, impose limitations on (i) dividend payments or certain other
restricted payments or investments; (ii) the incurrence of additional
indebtedness and guarantees or issuance of additional stock; (iii) creation of
liens; (iv) mergers, consolidation or sales of substantially all of WESCO's
assets; (v) certain transactions among affiliates; (vi) payments by certain
subsidiaries to WESCO; and (vii) capital expenditures. In addition, the
revolving credit agreement requires WESCO to meet certain fixed charge coverage
tests depending on availability.

WESCO is permitted to pay dividends under certain limited circumstances.
At December 31, 2002 and 2001, no retained earnings were available for dividend
payments.

WESCO had $16.6 million and $1.0 million of outstanding letters of credit
at December 31, 2002 and 2001, respectively. These letters of credit are used as
collateral for interest rate swap agreements, potential obligation under
insurance programs as well as certain foreign commercial transactions. The fair
value of the letters of credit approximates the contract value.

11. CAPITAL STOCK

Preferred Stock

There are 20,000,000 shares of preferred stock authorized at a par value
of $.01 per share. The Board of Directors has the authority, without further
action by the stockholders, to issue all authorized preferred shares in one or
more series and to fix the number of shares, designations, voting powers,
preferences, optional and other special rights and the restrictions or
qualifications thereof. The rights, preferences, privileges and powers of each
series of preferred stock may differ with respect to dividend rates, liquidation
values, voting rights, conversion rights, redemption provisions and other
matters.

Common Stock

There are 210,000,000 shares of common stock and 20,000,000 shares of
Class B common stock authorized at a par value of $.01 per share. The Class B
common stock is identical to the common stock, except for voting and conversion
rights. The holders of Class B common stock have no voting rights. With certain
exceptions, Class B common stock may be converted, at the option of the holder,
into the same number of shares of common stock.

WESCO's Board of Directors has authorized a $25 million share repurchase
program that expires in May 2003. WESCO's common stock may be purchased at
management's discretion, subject to meeting certain financial ratios, in open
market transactions and the program may be discontinued at any time. Under
previous share repurchase programs, WESCO purchased 3,898,000 shares of its
common stock for $32.8 million pursuant to this program. No shares were
repurchased during 2002.

Current deferred income taxes changed from an asset of $8.3 million at
December 31, 2001 to a liability of $3.4 million at December 31, 2002. The
primary factors associated with the change in balance were tax accounting method
changes related to certain working capital items.

13. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income by the
weighted average common shares outstanding during the periods. Diluted earnings
per share are computed by dividing net income by the weighted average common
shares and common share equivalents outstanding during the periods. The dilutive
effect of common share equivalents is considered in the diluted earnings per
share computation using the treasury stock method.

Diluted ................................................ $ 0.49 $ 0.43 $ 0.70


Options to purchase 5.3 million and 4.4 million shares of common stock at
a weighted average exercise price of $8.37 per share and $10.24 per share were
outstanding as of December 31, 2002 and 2001, respectively, but were not
included in the computation of diluted earnings per share because the option
exercise prices were greater than the average market price of WESCO common
stock.

14. EMPLOYEE BENEFIT PLANS

A majority of WESCO's employees are covered by defined contribution
retirement savings plans for their service rendered subsequent to WESCO's
formation. U.S. employee contributions of not more than 6% of eligible
compensation are matched 50% by WESCO. WESCO's contributions for Canadian
employees range from 1% to 6% of eligible compensation based on years of
service. For the years ended December 31, 2002, 2001 and 2000, WESCO contributed
$4.9 million, $5.5 million and $5.5 million, respectively, which was charged to
expense. Contributions may be taken in the form of WESCO's stock at the
employee's election.

In addition, employer profit sharing contributions may be made at the
discretion of the Board of Directors and can be based on WESCO's financial
performance. No such contributions were made during 2002, 2001 or 2000.

15. STOCK INCENTIVE PLANS

Stock Purchase Plans

In connection with the Recapitalization, WESCO established a stock
purchase plan ("1998 Stock Purchase Plan") under which certain employees may be
granted an opportunity to purchase WESCO's common stock. The maximum number of
shares available for purchase may not exceed 427,720. There were no shares
issued in 2002, 2001 or 2000.

In 1994, WESCO established a stock purchase plan ("1994 Stock Purchase
Plan") under which certain employees were granted an opportunity to purchase
WESCO's common stock. Future purchases of shares under the 1994 Stock Purchase
Plan were terminated in conjunction with the establishment of the 1998 Stock
Purchase Plan.

Stock Option Plans

WESCO has sponsored four stock option plans, the 1999 Long-Term Incentive
Plan ("LTIP"), the 1998 Stock Option Plan, the Stock Option Plan for Branch
Employees and the 1994 Stock Option Plan. The LTIP was designed to be the
successor plan to all prior plans. Outstanding options under prior plans will
continue to be governed by their existing terms, which are substantially similar
to the LTIP. Any remaining shares reserved for future issuance under the prior
plans are available for issuance under the LTIP. The LTIP is administered by the
Compensation Committee of the Board of Directors.


46


An initial reserve of 6,936,000 shares of common stock has been authorized
for issuance under the LTIP. This reserve automatically increases by (i) the
number of shares of common stock covered by unexercised options granted under
prior plans that are canceled or terminated after the effective date of the LTIP
and (ii) the number of shares of common stock surrendered by employees to pay
the exercise price and/or minimum withholding taxes in connection with the
exercise of stock options granted under our prior plans.

Options granted vest and become exercisable over periods ranging from four
to five years or earlier based on WESCO achieving certain financial performance
criteria. If the financial performance criteria are not met, all the options
will vest after eight years. All options vest immediately in the event of a
change in control. Each option terminates on the tenth anniversary of its grant
date unless terminated sooner under certain conditions.

All awards under WESCO's stock incentive plans are designed to be issued
at fair market value.

The following sets forth shares of common stock reserved for future issuance at
December 31, 2002:



Stock Purchase Plan ................................... 135,830
LTIP .................................................. 6,824,260

Thereafter ........................................... 9,072


Rental expense for the years ended December 31, 2002, 2001 and 2000, was
$32.9 million, $32.5 million and $30.3 million, respectively.

WESCO has litigation arising from time to time in the normal course of
business. In management's opinion, any present litigation WESCO is aware of will
not materially affect WESCO's consolidated financial position, results of
operations or cash flows.

17. SEGMENTS AND RELATED INFORMATION

WESCO is engaged principally in one line of business - the sale of
electrical products and maintenance repair and operating supplies - which
represents more than 90% of the consolidated net sales, income from operations
and assets, for 2002, 2001 and 2000. WESCO has over 215,000 product stock
keeping units and markets over one million products for direct shipment
customers. It is impractical to disclose net sales by product, major product
group or service group. There were no material amounts of sales or transfers
among geographic areas and no material amounts of export sales.

The following table sets forth information about WESCO by geographic area:
