A World of Solutions

Building Lasting Customer Relationships With Expansive Service Offerings

You know WESCO as one of the world’s largest electrical 
distributors, efficiently and cost-effectively supplying one of 
the industry’s broadest product portfolios to approximately 
75,000 customers.  But we are much more than a typical 
distributor.  We’re an industry-leading provider of supply 
chain solutions, bringing an extensive array of value-added 
services and technical capabilities to our customers every 
day.  With our services and expertise, our customers can 
operate more efficiently, reduce their costs, and better plan 
and manage their projects. 

Whether we’re helping our customers solve problems and 
identify opportunities, prescribing technical solutions, 
managing their inventory and logistics, performing kitting 
and product assembly, or providing turnkey supply chain 
outsourcing through our integrated supply model, our 
services and technical expertise drive the majority of 
our product sales.  We enable customers to simplify and 
outsource parts of their supply chains, hold and manage less 
inventory, and reduce capital project management time and 
risks.  We also help them save money, become safer and more 
energy-efficient, and learn about the latest technologies.

Our solutions create long-term alliances with our customers 
and a steady source of revenues and profits for WESCO.  
In 2016, for example, we achieved contract renewal rates of 
over 95% with our Global Accounts and Integrated Supply 
customers.  This is proof of the value we bring and the lasting 
relationships it sustains.  This is also the foundation of our 
One WESCO strategy:  to expand our global customer base 
and relationships by integrating our portfolio of products, 
services, and suppliers into comprehensive supply chain 
solutions for our customers’ maintenance, repair, and 
operating (MRO) supplies, original equipment manufacturers 
(OEM) products, and capital project needs.

In 2017, we plan to continue expanding our service offerings 
and investing in technical resources and employee 
development.  Our service capabilities are a key differentiator 
and competitive advantage, and we expect them to increase 
customer satisfaction and help drive profitable growth in the 
years to come.

To Our Shareholders, 
Employees, and  
Business Partners

OUR RESULTS

2016 was a challenging year.  Sales and earnings per share declined 
versus prior year, but our results were within our original outlook 
range.  These results reflect the difficult economic and end market 
environment and the impact of lackluster demand on customer 
spending in the industries we serve.  We responded to these 
challenges by reducing our costs and streamlining our organization  
to enable investments in our growth initiatives.  We also simplified 
our capital structure and delivered strong free cash flow generation.  
As a result of these actions, we have further strengthened our 
business and are well-positioned to deliver improved results and  
a return to growth in 2017:   

  To support investments in our business and deliver improved 
shareholder returns, we strengthened our balance sheet and 
generated our strongest free cash flow performance in seven 
years at over 150% of net income.  We acquired Atlanta Electrical 
Distributors to strengthen our core in the U.S., and we exited 
2016 with our financial leverage back within our preferred range.  
In addition, we simplified our capital structure by redeeming 
our convertible debentures at the date of our first call option, 
which reduces our ongoing interest expense and eliminates 
future dilution associated with this debt instrument.  Finally, I am 
pleased to report that our stock price increase in 2016 resulted  
in a total shareholder return of over 50%.  

  To drive above-market sales growth, we continued to strengthen 
our products and services portfolio while executing our One 
WESCO strategy.  Improved sales management and training 
programs are focused on driving a broader and deeper 
penetration with existing customers and adding new customers 
in attractive verticals where we have compelling service value 
propositions.  We expanded our range of supply chain solutions, 
building on a key WESCO competitive strength and our deep 
roots in lean applications.  We now offer nearly 50 distinct 
services that provide value to our customers by reducing costs, 
increasing productivity, and improving safety and sustainability.  

  To deliver increased profitability, we continued our efforts 
to streamline our business, reduce structural costs, increase 
productivity, and drive execution of our pricing, sourcing, and 
margin improvement initiatives.  Over the last two years, we 
have reduced our workforce by more than 10% and consolidated 
or exited 40 branches.  At the same time, we added new talent 
across the organization and further invested in our sales, supply 
chain, and e-commerce functions.

As we enter 2017, we are seeing early signs of stabilization and 
recovery in our end markets.  With this improving economic 
backdrop, leveraged by our actions to streamline and strengthen 
our business, WESCO is well-positioned to return to profitable 
sales growth and continue to deliver strong free cash flow.  We are 
also encouraged by expectations for regulatory reform, corporate 
tax reform, and infrastructure spending, as well as their potential 
positive impact on future economic growth and customer spending 
and investment.  

OUR STRATEGY 

We are a leading electrical and industrial distributor in North 
America, supplying one million products to approximately 75,000 
customers, including a majority of the Fortune 500 companies.   
We have amassed the portfolio, supplier relationships, geographic 
footprint, talent, and expertise to deliver superior value to our 
customers.  

We are focused on building scale through organic growth and 
acquisitions while expanding the supply chain solutions we provide 
to our customers.  We operate in highly fragmented markets, 
providing us with ample opportunity to play a consolidator role.  

2016 Annual Report   |   A World of Solutions   3

Increased scale brings stronger customer and supplier relationships 
and, consequently, greater profitability and the ability to invest for 
future growth. 

Across the value chain, our customers are driving consolidation 
and outsourcing, while suppliers are looking for stronger channel 
partners to generate demand for their products.  This will result in 
a smaller number of larger relationships on both ends of our value 
chain.  WESCO is well-positioned to benefit from this trend.

OUR FUTURE

Our strong, capable, and committed management team and 
organization of 9,000 associates are focused on leveraging our 
extensive product and service portfolio, blue-chip customer and 
supplier relationships, and footprint to deliver superior results 
and create value for our shareholders.  We expect to return to our 
legacy of consistent profitable growth as our markets improve, 
and we remain focused on what we can control — our strategy, our 
investments, and our execution.

OUR PEOPLE

At our core, we are a service company — a people business.  We 
continue to invest in developing our workforce and have injected new 
talent into WESCO to run a more streamlined organization, increase 
the use of best-in-class processes and tools, and sharpen our focus 
on executing with excellence.  With the addition of a new CFO, our 
first-ever CIO, and additional talent in our sales, supply chain, and 
e-commerce functions, our team is now stronger than ever.

We aspire to be the employer of choice in our industry — able 
to attract, develop, motivate, and retain top talent.  In 2016, 
we continued our investments in mentoring, military veteran 
recruiting, and WESCO University training programs.  We conducted 
our bi-annual Employee Engagement Survey and are addressing 
opportunities to make WESCO an even better place to work.

WESCO’s ranking in Fortune Magazine’s World’s Most Admired 
Companies again improved in 2016 to number two in our industry 
group.  We also made positive progress on our diversity agenda as a 
third WESCO executive received the “Most Powerful and Influential 
Woman Award” from the Pennsylvania Diversity Council, and we 
were again recognized by the 2020 Women on Boards campaign.

OUR CULTURE

Lean continuous improvement is at the heart of WESCO’s culture 
and is the foundation of “how” we do business in all groups, in all 
functions, and in all locations.  We have been on our lean journey 
for more than a decade and have made great progress, but we see 
even greater opportunities in the future to reduce waste, compress 
cycle times, and improve the efficiency and effectiveness of the 
distribution value chain.

Social and environmental responsibility is also an important 
part of WESCO’s culture.  We met the energy-efficiency and waste 
reduction goals that we set for ourselves five years ago and plan to 
announce a new set of goals later this year.  We are also helping our 
customers improve their operations in the areas of lighting, energy 
management, renewable energy, water and waste mitigation, and 
green procurement.  Consistent with our lean principles, we will 
continue to measure our progress, seek improvement opportunities, 
and report on our performance.

IN APPRECIATION

Robert J. Tarr Jr. retired from the WESCO Board of Directors in  
May 2016 after 17 years of distinguished service.  During his tenure, 
Bob served as the Chairman of the Audit Committee and a member of 
the Executive, Nominating and Governance, Audit, and Compensation   
committees.  On behalf of the Board of Directors and the entire 
management team, we thank Bob for his outstanding leadership, 
dedication, counsel, and invaluable contributions to WESCO.

and extraordinary effort in providing outstanding service to our 
customers.  You are the engine that drives WESCO and delivers our 
competitive advantage.

commitment.  We are focused on combining our capabilities with 
yours to provide complete solutions for our customers.  Together,  
we look forward to excelling in 2017.

confidence.  We are committed to continually strengthening our 
business and increasing shareholder value.

Supply Chain Solutions

In today’s challenging marketplace, companies are 
looking for ways to simplify their supply chains  
and reduce their costs.  We work with our customers  
to understand their needs, and we design and 
implement customized solutions that meet their 
specific requirements.  We offer customized sourcing, 
procurement, demand and inventory management, 
warehousing, and logistics solutions that remove 
waste, improve efficiencies, and provide tangible 
savings.  In 2016, the number of plants outsourcing 
their MRO management and supply function to 
WESCO’s Integrated Supply business increased by 5%.  
We recently added a suite of WESCO e-commerce 
solutions, including next-generation inventory 
management and vending solutions, to deliver value 
to our customers.

WESCO IN ACTION

A customer’s factory lacked an efficient inventory 
control and tool tracking process to manage over 
6,500 items in multiple equipment cribs.  This led 
to excessive spending and production downtime 
across the factory.  Management selected WESCO’s 
e-Crib solution for this and other factories, 
enabling them to quickly locate parts, track their 
usage, and better control expensive tooling.  As a 
result, downtime and labor-related tool requests 
were reduced by up to 98%, resulting in significant 
efficiency gains.  Additionally, more than a third of 
the 6,500 items were identified as surplus.

Capital Project Solutions

WESCO has decades of experience providing electrical and instrumentation 
material and material management solutions for the non-residential 
construction, global energy, mining and materials, power, and 
infrastructure markets.  We understand the importance of cost and 
schedule to our customers’ major projects.  

With skilled labor at a premium, avoiding downtime and increasing 
productivity are always on the minds of our contractor customers.  
WESCO’s Lean Construction Processes provide solutions to help customers 
complete capital projects on time and within budget.  We work with 
them to map out project activities, and we deliver exactly what will be 
needed on the jobsite each day.  We also offer custom solutions, like cable 
management, kitting, pre-fabrication, and assembly, saving thousands of 
hours of on-site installation time for our contractor partners and enabling 
costly skilled labor to focus on more technical tasks.   

WESCO’s materials management services provide significant savings by 
leveraging project spend, enabling global sourcing, reducing surplus 
material, and increasing craft productivity.  WESCO’s proprietary material 
management software, called RPM, is a robust, centralized, web-based 
system that provides complete project visibility and transparency.  We 
order, receive, organize, stage, store, and deliver materials to jobsites 
in support of the project schedule.  We stock customized carts with the 
materials the electrician will need for each day’s work.  Major materials are 
staged and stored at WESCO’s branches and distribution centers until they 
are needed at the jobsite. 

WESCO IN ACTION

A major integrated oil 
company engaged WESCO to 
provide complete material 
management for a $750 
million plant expansion.  The 
project involves an EPC firm, 
a general contractor, and two 
electrical and instrumentation 
subcontractors.  WESCO is 
providing complete material 
management services, 
including material take-offs, 
sourcing, local warehousing, 
kitting, and cable management, 
along with on-site trailers and 
personnel.

Customized Product Solutions

Hundreds of customers rely on WESCO to assemble electrical, wiring, 
and other components into kits, sub-assemblies, and products.  This 
simplifies our customers’ operations and enables them to focus on their 
core capabilities.  WESCO is a leading provider of electrical-based OEM 
products, leveraging our lean service models and blue-chip global supplier 
base.  Our products and services enable our customers to reduce their 
costs and inventory levels, while simplifying and increasing the flexibility 
of their supply chains.  In short, we help them to better compete in a global 
manufacturing world. 

Our sales professionals work face-to-face with our customers to create 
customized solutions and build business advisory relationships on a 
foundation of credibility, respect, and trust.  We create automation 
control systems that offer flexibility for meeting our customers’ unique 
requirements and incorporate products from preferred suppliers.  Our 
customers benefit from leveraging WESCO’s cost structure and find value in 
using us to both assemble and distribute their products.

WESCO IN ACTION

An offshore crane manufacturer 
needed a source to develop  
and assemble electrical control 
boxes and kits to allow for quick 
assembly in the field.  WESCO 
worked with the customer’s 
50-year-old prints and was  
able to update those to enable 
an aftermarket upgrade 
solution.  WESCO has the 
in-house capabilities to provide 
a complete design, build, and 
delivery solution.

Technical Expert Solutions

For many of our customers, WESCO is an extension of their engineering 
and manufacturing capabilities.  We have technical experts in each of our 
major product categories who advise customers on the latest products and 
technologies and help them select the right solutions for their specific need.  

Every day, our sales and technical experts help our customers identify 
opportunities and define, purchase, and implement the right solutions to 
make their operations or projects more cost-effective, efficient, and reliable.  
In 2015, we acquired Aelux and Lumigent to design energy-efficient lighting 
and controls retrofits for our commercial, industrial, and institutional 
customers across North America.  We team up with our suppliers to bring 
the best-available new products and alternatives to our customers.  We 
also offer a variety of training to keep our customers up-to-date on new 
concepts, new products, and new technologies.

WESCO’s Global Accounts team leverages our global footprint, key 
relationships with multi-national manufacturers, and best-cost regional 
sourcing to support our customers’ locations around the world.  We offer 
a comprehensive set of supply chain solutions, including local inventory, 
staging of long lead items, ocean and air freight, customs clearance, and 
export/import compliance.  Our integrated operating model allows WESCO 
to seamlessly implement agreements across multiple countries and provide 
customers with the opportunity to leverage their global spend, normalize 
key commercial terms, and drive product standardization.

WESCO IN ACTION

WESCO won a five-year Global 
Account contract to perform 
a national lighting upgrade 
and supply MRO materials for 
over 10 million square feet 
of customer space.  We are 
providing a complete material 
supply program using third-
party service partners and 
installers, and are utilizing 
advanced WESCO lighting 
and energy management 
capabilities.  This multi-
category win was made possible 
by our One WESCO strategy 
and our extensive product and 
service expertise.

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.

The Company

WESCO International, Inc. (“WESCO International”), incorporated in 1993 and effectively formed in February 1994 upon 

acquiring a distribution business from Westinghouse Electric Corporation, is a leading North American-based distributor of 
products and provider of advanced supply chain management and logistics services used primarily in industrial, construction, 
utility, and commercial, institutional and government (“CIG”) markets. We are a leading provider of electrical, industrial, and

construction materials, and advanced supply chain management and logistics services. Our primary product categories include 
general supplies, wire, cable and conduit, communications and security, electrical distribution and controls, lighting and 
sustainability, and automation, controls and motors.

We serve approximately 75,000 active customers globally through approximately 500 full service branches primarily 
located in North America, with operations in 14 additional countries and nine distribution centers located in the United States 
and Canada. The Company employs approximately 9,000 employees worldwide. We distribute over 1,000,000 products, 
grouped into six categories, from more than 25,000 suppliers, utilizing a highly automated, proprietary electronic procurement 
and inventory replenishment system.

In addition, we offer a comprehensive portfolio of value-added capabilities, which includes supply chain management, 
logistics and transportation, procurement, warehousing and inventory management, as well as kitting, limited assembly of 
products and system installation. Our value-added capabilities, extensive geographic reach, experienced workforce and broad 
product and supply chain solutions have enabled us to grow our business and establish a leading position in North America.

Industry Overview

We operate in highly fragmented markets that include thousands of small regional and locally based, privately owned 
competitors. According to one industry publication, in 2015, the latest year for which market data is available, the five largest 
full-line electrical distributors in North America, including WESCO, accounted for approximately 33% of an estimated $100 
billion-plus of electrical sales in North America. Our global account, integrated supply and OEM programs provide customers 
with regional, national, North American and global supply chain consolidation opportunities. The demand for these programs is 
driven primarily by the desire of companies to reduce operating expenses by outsourcing operational and administrative 
functions associated with the procurement, management and utilization of MRO supplies and OEM components. We believe 
that opportunities exist for expansion of these programs. The total potential in the United States for purchases of MRO and 
OEM supplies and services across all industrial distribution market segments and channels is estimated to be nearly 
$500 billion per a combination of industry sources.

According to various industry sources, electrical distribution industry sales have grown low-single-digits on average over 

the past three years, despite a low-single-digit decline in 2016. Growth in recent years has been driven by new products, 
technologies and applications. It is estimated that approximately 75% of electrical products sold in the United States are 
delivered to the end user through the distribution channel.

Industrial. Sales to industrial customers of MRO, OEM, and construction products and services accounted for 

approximately 36% of our sales in 2016, compared to 39% in 2015. Industrial sales product categories include a broad range of 
electrical equipment and supplies as well as lubricants, pipe, valves, fittings, fasteners, cutting tools, power transmission, and 
safety products. In addition, OEM customers require a reliable supply of assemblies and components to incorporate into their 
own products as well as value-added services such as supplier consolidation, design and technical support, just-in-time supply 
and electronic commerce, and supply chain management.

Construction. Sales of electrical and communications products to contractors accounted for approximately 34% of our sales 

in 2016, compared to 32% in 2015. Customers include a wide array of contractors and engineering, procurement and 
construction firms for industrial, infrastructure, commercial and data and broadband communications projects. Specific 
applications include projects for refineries, railways, hospitals, wastewater treatment facilities, data centers, security 
installations, offices, and modular and mobile homes. In addition to a wide array of electrical products, we offer contractors 
communications products for projects related to IT/network modernization, physical security upgrades, broadband 
deployments, network security, and disaster recovery.

Utility. Sales to utilities and utility contractors accounted for approximately 16% of our sales in 2016, compared to 15% in 
2015. Customers include large investor-owned utilities, rural electric cooperatives, municipal power authorities and contractors 
that serve these customers. We provide our utility customers with products and services to support the construction and 
maintenance of their generation, transmission and distribution systems along with an extensive range of products that meet 
their power plant MRO and capital projects needs. Materials management and procurement outsourcing arrangements are also 
important in this market, as cost pressures and deregulation have caused utility customers to seek improvements in the 
efficiency and effectiveness of their supply chains.

Commercial, Institutional and Government ("CIG"). Sales to CIG customers accounted for approximately 14% of our 
sales in 2016 and 2015. Customers include schools, hospitals, property management firms, retailers and federal, state and local 
government agencies of all types, including federal contractors.

Business Strategy

Our goal is to grow organically at a rate greater than that of our industry while making accretive acquisitions. Our organic 
growth strategy focuses on enhancing our sales, technical expertise and customer service capabilities to acquire new customers 
and increase our sales to current customers, broaden our product and service offerings and expand our geographic footprint. We 
utilize LEAN continuous improvement initiatives on a company-wide basis to deliver operational excellence and improve 
productivity. We also extend our LEAN initiatives to customers to improve the efficiency and effectiveness of their operations 
and supply chains. In addition, we seek to develop a distinct competitive advantage through talent management and employee 
development processes and programs.

We have identified certain growth engines that we believe provide substantial opportunities for above-market growth, and 
have developed strategies to address each of these areas of opportunity. These growth engines are a combination of business 
models, selected end markets and product categories, as discussed below.

Grow Our Global Account Customer Relationships and Base. Our typical global account customer is a large, multi-
location industrial or commercial company, a large utility, a major contractor, or a government or institutional customer. Our 
global account program is designed to provide customers with supply chain management services and cost reductions by 
coordinating and standardizing activity for MRO materials and OEM direct materials across their multiple locations, utilizing 
our broad geographic footprint and our largely integrated information technology platform. Comprehensive account plans are 
developed and managed at the local, national and international levels to prioritize activities, identify key performance 

2

 
 
 
measures, and track progress against objectives. We involve our preferred suppliers early in the implementation process to 
contribute expertise and product knowledge to accelerate program implementation and delivery of cost savings and process 
improvements.

We plan to continue to expand our product and service offerings to existing global account customers, and increase our 
reach to serve additional customer locations. We plan on expanding our customer base by capitalizing on our industry expertise 
and supply chain optimization capabilities.

Extend Our Position in Integrated Supply Programs. Our integrated supply programs focus on optimizing the supply chain 

and replacing the traditional multi-vendor, resource-intensive procurement process with a single, outsourced, automated 
process. Each integrated supply program employs our product and distribution expertise to reduce the number of suppliers, total 
procurement costs, and administrative expenses, while meeting the customers’ service needs and improving their operating 
controls. We believe that large customers will seek to utilize such services to consolidate and simplify their MRO and OEM 
supply chains. 

We are expanding our position in North America as an integrated supply service provider by building upon established 
relationships within our large customer base and premier supplier network, and extending our services to additional customers 
and locations around the world. Our services are offered across all four of our end markets.

Expand Our Relationships with Construction Contractors. We support new construction, renovation and retrofit projects 

across a wide variety of vertical markets, including manufacturing, healthcare, education, enterprise data communications, 
telecommunications, energy and government infrastructure. We believe that significant cross selling opportunities exist for our 
electrical and communications products and expertise, and we plan to use our global account and integrated supply programs, 
LEAN initiatives and project management expertise to capitalize on new non-residential construction opportunities.

Expand Products and Services for Utilities. Our investor-owned, public power and utility contractor customers continue to 
focus on improving grid reliability and operating efficiency, while reducing costs. As a result, we anticipate opportunities from 
distribution grid improvement and transmission expansion projects as well as the adoption of integrated supply programs. 
Accordingly, we are focused on expanding our logistical and project services and supply chain management programs to 
increase our scope of supply on distribution grid, generation and other energy projects, including alternative energy projects.

Invest in Industrial MRO and Safety. Our sales of industrial maintenance, repair, and operating supply (MRO) materials 
include a broad range of electrical and non-electrical products used in the ongoing maintenance and repair of equipment used in 
production processes. These products are also used for facility upkeep in manufacturing, commercial, institutional, and other 
operations. In addition, through acquisitions, we have expanded our safety products, personal protection safety equipment, first 
aid supplies, and OSHA compliance categories to complement the industrial MRO product lines.

Expand International Operations. We seek to capitalize on existing and emerging international market opportunities 

through the expansion of our global product and service platforms. We follow large existing global customers into international 
markets, extending our procurement outsourcing, integrated supply programs and supplier relationships. Once established, we 
also seek to develop new business opportunities in these markets. We believe this strategy of working with well-developed 
customer and supplier relationships significantly reduces risk and provides the opportunity to establish profitable business. Our 
priorities are focused on global vertical markets including energy, mining and metals, manufacturing, and infrastructure, as well 
as key product categories such as communications and security.

Grow Our Communications Products Position. Over the last several years, there has been a convergence of electrical and 
data communications contractors. Our ability to provide both electrical and communications products and services lines as well 
as automation, electromechanical, non-electrical MRO, physical security and utility products has presented cross selling 
opportunities across WESCO. Communications products are in continual demand due to network upgrades, low voltage 
security investments, data center upgrades and increasing broadband and telecommunications usage.

Grow Lighting System and Sustainability Sales. Lighting applications are undergoing significant innovation, driven by 

energy efficiency and sustainability trends. We have expanded our sales team and marketing initiatives and increased our 
presence and customer base with the acquisition of Needham Electric Supply. We expect to continue to add product and service 
offerings to provide lighting and energy-saving solutions. 

Pursue Strategic Acquisitions. In 2016, we acquired Atlanta Electrical Distributors, LLC, which expanded our construction 

end market presence in the growing Southeastern United States. Since 2010, we have made fourteen acquisitions that have 
helped us strengthen our product and services portfolio and increase our customer base, as well as provide an important source 
of talent.

We believe that the highly fragmented nature of the electrical and industrial distribution industry will continue to provide 

acquisition opportunities.

Drive Operational Excellence. LEAN continuous improvement is a set of company-wide strategic initiatives to increase 
efficiency and effectiveness across the entire business enterprise, including sales, operations and administrative processes. The 
basic principles behind LEAN are to systematically identify and implement improvements through simplification, elimination 
of waste and reduction in errors. We apply LEAN in our distribution environment, and develop and deploy numerous initiatives 
through the Kaizen approach targeting improvements in sales, margin, warehouse operations, transportation, purchasing, 
working capital management and administrative processes. Our objective is to continue to implement LEAN initiatives across 
our business enterprise and to extend LEAN services to our customers and suppliers.

Talent Management. We seek to develop a distinct competitive advantage through talent management and employee 
engagement and development. We believe our ability to attract, develop and retain diverse human capital is imperative to 
ongoing business success. We improve workforce capability through various programs and processes that identify, recruit, 
develop and promote our talent base. Significant enhancements in these programs have been made over the last several years, 
and we expect to continue to refine and enhance these programs in the future.

Competitive Strengths

As a leading electrical distributor in a highly fragmented North American market, we compete directly with global, national, 

regional and local distributors of electrical and other industrial supplies, along with buying groups formed by smaller 
distributors. Competition is generally based on product line breadth, product availability, service capabilities and price. We 
believe that our market leadership, broad product offering and value-added services, extensive distribution network and low-
cost operator status provide distinct competitive advantages. 

Market Leadership. Our ability to manage complex global supply chains, and multi-site facility maintenance programs and 
construction projects, which require special sourcing, technical advice, logistical support and locally based service, has enabled 
us to establish a strong presence in the competitive and fragmented North American electrical distribution market.

Broad Product Offering and Value-added Services. We provide a wide range of products, services and procurement 

solutions, which draw on our product knowledge, supply and logistics expertise, system capabilities and supplier relationships 
to enable our customers to maximize productivity, minimize waste, improve efficiencies, reduce costs and enhance safety. Our 
broad product offering and stable source of supply enables us to consistently meet customers’ wide-ranging capital project, 
MRO and OEM requirements.

Extensive Distribution Network. We operate approximately 500 geographically dispersed branch locations and nine 
distribution centers (five in the United States and four in Canada). Our distribution centers add value for our customers, 
suppliers, and branches through the combination of a broad and deep selection of inventory, online ordering and next-day 
shipment capabilities, and central order handling and fulfillment. Our distribution center network reduces the lead time and cost 
of supply chain activities through its automated replenishment and warehouse management system, and provides economies of 
scale in purchasing, inventory management, administration and transportation. This extensive network, which would be 
difficult and expensive to replicate, allows us to:

•  Enhance localized customer service, technical support and sales coverage;

•  Tailor individual branch products and services to local customer needs, and

•  Offer multi-site distribution capabilities to large customers and global accounts.

Low-Cost Operator. Our competitiveness has been enhanced by our consistent favorable operating cost position, which is 
based on the use of LEAN, strategically-located distribution centers, and purchasing economies of scale. As a result of these 
and other factors, our operating cost as a percentage of sales is one of the lowest in our industry. Our selling, general and 
administrative expenses as a percentage of revenues for 2016 were 14.3%.

a distribution center to enhance the service capabilities of the local branches. Sales in Mexico represented approximately 1% of 
our total sales in 2016.

Other International. We sell to global customers through export sales offices located in Calgary, Houston, Miami, Montreal 

and Pittsburgh within North America and sales offices and branch operations in various international locations. Sales from 
other international locations represented approximately 3% of our total sales in 2016. Our branches in Aberdeen, Scotland, 
Dublin, Ireland and Manchester, England support sales efforts in Europe and the Middle East. We have branches in Singapore 
and Thailand to support our sales to Asia and a branch near Shanghai to serve customers in China. Furthermore, we support 
sales in South America through our branches in Chile, Ecuador and Peru, and we have operations in five additional countries. 
Many of our international locations have been established to serve our growing list of customers with global operations.

Intellectual Property

We currently have trademarks, patents and service marks registered with the U.S. Patent and Trademark Office and 
Canadian Intellectual Property Office. The trademarks and service marks registered in the U.S. include: “WESCO®”, our 
corporate logo and the running man logo. The Company's "EECOL" trademark is registered in Canada. In addition, trademarks, 
patents, and service mark applications have been filed in various foreign jurisdictions, including Canada, Chile, China, the 
European Community, Hong Kong, Mexico, Singapore, Thailand and the United Kingdom.

Environmental Matters

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

and human health and safety. Some of these laws and regulations may impose strict, joint and several liabilities 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 do not 

anticipate making significant capital expenditures for environmental control matters either in the current year or in the near 
future.

Seasonality

Sales during the first quarter are affected by a reduced level of activity. Sales during the second, third and fourth quarters 

are generally 5 - 7% higher than the first quarter. Sales typically increase beginning in March, with slight fluctuations per 
month through October. During periods of economic expansion or contraction our sales by quarter have varied significantly 
from this seasonal pattern.

Item 1A. Risk Factors.

The following factors, among others, could cause our actual results to differ materially from the forward-looking statements 

we make. All forward-looking statements attributable to us or persons working on our behalf are expressly qualified by the 
following factors. This information should be read in conjunction with Item 7, Management’s Discussion and Analysis of 
Financial Condition and Results of Operations, Item 7A, Quantitative and Qualitative Disclosures about Market Risks and the 
consolidated financial statements and related notes included in this Form 10-K.

Adverse conditions in the global economy and disruptions of financial markets could negatively impact our results of 
operations. 

Our results of operations are affected by the level of business activity of our customers, which in turn is affected by global 

economic conditions and market factors impacting the industries and markets that they serve. Certain global economies and 
markets continue to experience significant uncertainty and volatility, particularly commodity-driven end markets such as oil 
and gas and metals and mining. Adverse economic conditions or lack of liquidity in these markets, particularly in North 
America, may adversely affect our revenues and operating results. Economic and financial market conditions also affect the 
availability of financing for projects and for our customers' capital or other expenditures, which can result in project delays or 
cancellations and thus affect demand for our products. There can be no assurance that any governmental responses to economic 
conditions or disruptions in the financial markets ultimately will stabilize the markets or increase our customers' liquidity or the 
availability of credit to our customers. Should one or more of our larger customers declare bankruptcy, it could adversely affect 
the collectability of our accounts receivable, bad debt reserves and net income. In addition, our ability to access the capital 
markets may be restricted at a time when we would like, or need, to do so. The economic, political and financial environment 
also may affect our business and financial condition in ways that we currently cannot predict, and there can be no assurance 
that economic, political and market conditions will not adversely affect our results of operations, cash flow or financial position 
in the future. Fluctuations of the U.S. dollar relative to other currencies could negatively affect our business, financial results 
and liquidity.

Certain events or conditions, including a failure or breach of our information security systems, could lead to 
interruptions in our operations, which may materially adversely affect our business, financial condition or results of 
operations. 

We operate a number of facilities and we coordinate company activities, including information technology systems and 
administrative services and the like, through our headquarters operations. Our operations depend on our ability to maintain 
existing systems and implement new technology, which includes allocating sufficient resources to periodically upgrade our 
information technology systems, and to protect our equipment and the information stored in our databases against both 
manmade and natural disasters, as well as power losses, computer and telecommunications failures, technological breakdowns, 
unauthorized intrusions, cyber-attacks, and other events. Conversions to new information technology systems may result in cost 
overruns, delays or business interruptions. If our information technology systems are disrupted, become obsolete or do not 
adequately support our strategic, operational or compliance needs, it could result in competitive disadvantage and adversely 
affect our financial results and business operations, including our ability to process orders, receive and ship products, maintain 
inventories, collect accounts receivable and pay expenses. 

Because we rely heavily on information technology both in serving our customers and in our enterprise infrastructure in 

order to achieve our objectives, we may be vulnerable to damage or intrusion from a variety of cyber-attacks including 
computer viruses, worms or other malicious software programs that access our systems. Despite the precautions we take to 
mitigate the risks of such events, an attack on our enterprise information technology system could result in theft or disclosure of 
our proprietary or confidential information or a breach of confidential customer, supplier or employee information. Such events 
could have an adverse impact on revenue and harm our reputation. Additionally, such an event could cause us to incur legal 
liability and costs, which could be significant, in order to address and remediate the effects of an attack and related security 
concerns. 

We also depend on accessible office facilities, distribution centers and information technology data centers for our 

operations to function properly. An interruption of operations at any of our distribution centers could have a material adverse 
effect on the operations of branches served by the affected distribution center. Such disaster related risks and effects are not 
predictable with certainty and, although they typically can be mitigated, they cannot be eliminated. We seek to mitigate our 
exposures to disaster events in a number of ways. For example, where feasible, we design the configuration of our facilities to 
reduce the consequences of disasters. We also maintain insurance for our facilities against casualties and we evaluate our risks 
and develop contingency plans for dealing with them. Although we have reviewed and analyzed a broad range of risks 
applicable to our business, the ones that actually affect us may not be those we have concluded most likely to occur. 
Furthermore, although our reviews have led to more systematic contingency planning, our plans are in varying stages of 

9

development and execution, such that they may not be adequate at the time of occurrence for the magnitude of any particular 
disaster event that befalls us.

Loss of key suppliers, product cost fluctuations, lack of product availability or inefficient supply chain operations 
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 

2016 accounted for approximately 32% of our purchases for the period. Our largest supplier in 2016 was Eaton Corporation, 
accounting for approximately 11% of our purchases. The loss of, or a substantial decrease in the availability of, products from 
any of these suppliers, a supplier's change in sales strategy to rely less on distribution channels, the loss of key preferred 
supplier agreements, or disruptions in a key supplier's operations could have a material adverse effect on our business. Supply 
interruptions could arise from shortages of raw materials, effects of economic, political or financial market conditions on a 
supplier's operations, labor disputes or weather conditions affecting products or shipments, transportation disruptions, 
information system disruptions or other reasons beyond our control. 

In addition, certain of our products, such as wire and conduit, are commodity-price-based products and may be subject to 

significant price fluctuations which are beyond our control. While increases in the cost of energy or products could have 
adverse effects, decreases in those costs, particularly if severe, could also adversely impact us by creating deflation in selling 
prices, which could cause our gross profit margin to deteriorate. Fluctuations in energy or raw materials costs can also 
adversely affect our customers. The recent declines in oil and gas prices have negatively impacted our customers operating in 
those industries and, consequently, our sales to those customers. 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 cause us to be at a competitive disadvantage. The profitability of our business is also dependent upon the efficiency of 
our supply chain. An inefficient or ineffective supply chain strategy or operations could increase operational costs, reduce profit 
margins and adversely affect our business.

Expansion into new business activities, industries, product lines or geographic areas could subject the company to 
increased costs and risks and may not achieve the intended results.

Engaging in or significantly expanding business activities in product sourcing, sales and services could subject the company 

to unexpected costs and risks. Such activities could subject us to increased operating costs, product liability, regulatory 
requirements and reputational risks. Our expansion into new and existing markets, including manufacturing related or regulated 
businesses, may present competitive, distribution and regulatory challenges that differ from current ones. We may be less 
familiar with the target customers and may face different or additional risks, as well as increased or unexpected costs, compared 
to existing operations. Growth into new markets may also bring us into direct competition with companies with whom we have 
little or no past experience as competitors. To the extent we are reliant upon expansion into new geographic, industry and 
product markets for growth and do not meet the new challenges posed by such expansion, our future sales growth could be 
negatively impacted, our operating costs could increase, and our business operations and financial results could be negatively 
affected. Expanding our e-commerce capabilities and customer experience has required additional investments, and if not 
successful, we may not realize the return on our investments as anticipated or our operating results could be adversely affected 
by slower than expected sales growth or additional costs.

We must attract, retain and motivate key employees, and the failure to do so may adversely affect our business and 
results of operations. 

Our success depends on hiring, retaining and motivating key employees, including executive, managerial, sales, technical, 

marketing and support personnel. We may have difficulty locating and hiring qualified personnel. In addition, we may have 
difficulty retaining such personnel once hired, and key people may leave and compete against us. The loss of key personnel or 
our failure to attract and retain other qualified and experienced personnel could disrupt or adversely affect our business, its 
sales and results of operations. In addition, our operating results could be adversely affected by increased costs due to increased 
competition for employees, higher employee turnover, which may also result in loss of significant customer business, or 
increased employee benefit costs.

Changes in tax laws or challenges to the Company's tax positions by taxing authorities could adversely impact the 
Company's results of operations and financial condition.

We are subject to taxes in jurisdictions in which we do business, including but not limited to taxes imposed on our income, 

receipts, stockholders' equity, property, sales, purchases and payroll. As a result, the tax expense we incur can be adversely 
affected by changes in tax law. We frequently cannot anticipate these changes in tax law, which can cause unexpected volatility 
in our results from operations. While not limited to the United States and Canada, changes in the tax law at the federal and 
state/provincial levels in the United States and Canada can have a materially adverse effect on our results from operations.

10

Additionally, the tax laws to which the Company is subject are inherently complex and ambiguous. Therefore, we must 
interpret the applicable laws and make subjective judgments about the expected outcome upon challenge by the applicable 
taxing authorities. As a result, the impact on our results from operations of the application of enacted tax laws to our facts and 
circumstances is frequently uncertain. If a tax authority successfully challenges our interpretation and application of the tax law 
to our facts and circumstances, there can be no assurance that we can accurately predict the outcome and the taxes ultimately 
owed upon effective settlement may differ from the tax expense recognized in our consolidated statements of income and 
comprehensive income (loss) and accrued in our consolidated balance sheets. Additionally, if we cannot meet liquidity 
requirements in the United States, we may have to repatriate funds from overseas, which would result in a United States tax 
liability on the amount repatriated. 

An increase in competition could decrease sales or earnings. 

We operate in a highly competitive industry and compete directly with global, national, regional and local providers of our 

products and services. Some of our existing competitors have, and new market entrants may have, greater resources than us. 
Competition 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 as well as e-commerce companies. There may be new market entrants with non-traditional business and 
customer service models, resulting in increased competition and changing industry dynamics. 

Existing or future competitors may seek to gain or retain market share by reducing prices, and we may be required to lower 

our prices or may lose business, which could adversely affect our financial results. Also, to the extent that we do not meet 
changing customer preferences or demands or to the extent that one or more of our competitors becomes more successful with 
private label products, on-line offerings or otherwise, our ability to attract and retain customers could be materially adversely 
affected. 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 industry consolidation could affect our growth and profit margins.

Acquisitions that we may undertake would involve a number of inherent risks, any of which could cause us not 
to realize the benefits anticipated to result.

We have expanded our operations through organic growth and selected acquisitions of businesses and assets and may seek 
to do so in the future. Acquisitions involve various inherent risks, including: problems that could arise from the integration of 
the acquired business; uncertainties in assessing the value, strengths, weaknesses, contingent and other liabilities and potential 
profitability of acquisition candidates; the potential loss of key employees of an acquired business; the ability to achieve 
identified operating and financial synergies anticipated to result from an acquisition or other transaction; unanticipated changes 
in business, industry or general economic conditions that affect the assumptions underlying the acquisition or other transaction 
rationale; and expansion into new countries or geographic markets where we may be less familiar with operating requirements, 
target customers and regulatory compliance. Any one or more of these factors could increase our costs or cause us not to realize 
the benefits anticipated to result from the acquisition of business or assets.

While there are risks associated with acquisitions generally, including integration risks, there are additional risks more 
specifically associated with owning and operating businesses internationally, including those arising from import and export 
controls, foreign currency exchange rate changes, material developments in political, regulatory or economic conditions 
impacting those operations and various environmental and climatic conditions in particular areas of the world.

Fluctuations in foreign currency have an effect on reported results from operations. 

The results of our foreign operations are reported in the local currency and then translated into U.S. dollars at the applicable 
exchange rates for inclusion in our consolidated financial statements. The exchange rates between some of these currencies and 
the U.S. dollar have fluctuated significantly in recent years, and may continue to do so in the future. In addition, because our 
financial statements are stated in U.S. dollars, such fluctuations may affect our results of operations and financial position, and 
may affect the comparability of our results between financial periods.  

We are subject to costs and risks associated with laws and regulations affecting our business, as well as litigation for 
product liability or other matters affecting our business. 

The complex legal and regulatory environment exposes us to compliance costs and risks, as well as litigation and other legal 

proceedings, which could materially affect our operations and financial results. These laws and regulations may change, 
sometimes significantly, as a result of political or economic events, and some changes are anticipated to occur in the coming 
year. They include tax laws and regulations, import and export laws and regulations, labor and employment laws and 
regulations, product safety, occupational safety and health laws and regulations, securities and exchange laws and regulations 
(and other laws applicable to publicly-traded companies such as the Foreign Corrupt Practices Act), and environmental laws 

11

and regulations. Furthermore, as a government contractor selling to federal, state and local government entities, we are also 
subject to a wide variety of additional laws and regulations. Proposed laws and regulations in these and other areas, such as 
healthcare, employment, or legal matters could affect the cost of our business operations. From time to time we are involved in 
legal proceedings, audits or investigations which may relate to, for example, product liability, labor and employment (including 
wage and hour), tax, escheat, import and export compliance, government contracts, worker health and safety, general 
commercial and securities matters. While we believe that the outcome of any pending matter is unlikely to have a material 
adverse effect on our financial condition or liquidity, additional legal proceedings may arise in the future and the outcome of 
any legal proceedings and other contingencies could require us to take actions which could adversely affect our operations or 
could require us to pay substantial amounts of money.

Our outstanding indebtedness requires debt service commitments that could adversely affect our ability to fulfill our 
obligations and could limit our growth and impose restrictions on our business. 

As of December 31, 2016, we had $1.40 billion of consolidated indebtedness (excluding debt discount and debt issuance 

costs), including $500 million in aggregate principal amount of 5.375% Senior Notes due 2021 (the “2021 Notes”), $350 
million in aggregate principal amount of 5.375% Senior Notes due 2024 (the “2024 Notes”) and $144.8 million in aggregate 
principal amount of term loans due 2019 (the “Term Loan Facility”). Our consolidated indebtedness also includes amounts 
outstanding under our revolving credit facility (the "Revolving Credit Facility"), which has an aggregate borrowing capacity of 
$600 million, and our accounts receivable securitization facility (the “Receivables Facility”), through which we sell up to $550 
million of our accounts receivable to third-party financial institutions. We and our subsidiaries may undertake additional 
borrowings in the future, subject to certain limitations contained in the instruments governing our indebtedness.

Our debt service obligations have important consequences, including: our payments of principal and interest reduce the 

funds available to us for operations, future business opportunities and acquisitions and other purposes; they increase our 
vulnerability to adverse economic, financial market and industry conditions; our ability to obtain additional financing may be 
limited; and our financial results are affected by increased interest costs. Our ability to make scheduled payments of principal 
and interest on our debt, refinance our indebtedness, make scheduled payments on our operating leases, fund planned capital 
expenditures or to 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. Our Receivables Facility is subject to renewal in September 2018 and our Revolving Credit 
Facility is subject to renewal in September 2020. There can be no assurance that available funding or any sale of additional 
receivables or additional financing will be possible at the times of renewal in amounts or terms favorable to us, if at all.     

Over the next three years, we will be required to repay approximately $548.5 million of our currently outstanding 

indebtedness, of which $380.0 million is related to our Receivables Facility, $144.8 million is related to our Term Loan Facility, 
$20.9 million is related to our international lines of credit, and $2.8 million is related to our capital leases.

Our debt agreements contain restrictions that may limit our ability to operate our business. 

Our credit facilities also require us to maintain specific earnings to fixed expenses and to meet minimum net worth 

requirements in certain circumstances. Our credit facilities, Term Loan Facility, 2021 Notes and 2024 Notes contain, and any of 
our future debt agreements may contain, certain covenant restrictions that limit our ability to operate our business, including 
restrictions on our ability to: incur additional debt or issue guarantees; create liens; make certain investments; enter into 
transactions with our affiliates; sell certain assets; make capital expenditures; redeem capital stock or make other restricted 
payments; declare or pay dividends or make other distributions to stockholders; and merge or consolidate with any person. Our 
Term Loan Facility and certain other credit facilities contain additional affirmative and negative covenants, and our ability to 
comply with these covenants is dependent on our future performance, which will be subject to many factors, some of which are 
beyond our control, including prevailing economic conditions.      

As a result of these covenants, our ability to respond to changes in business and economic conditions and to obtain 
additional financing, if needed, may be significantly restricted, and we may be prevented from engaging in transactions that 
might otherwise be beneficial to us. In addition, our failure to comply with these covenants could result in a default under the 
credit facilities, Term Loan Facility, 2021 Notes, 2024 Notes and our other debt, which could permit the holders to accelerate 
such debt. If any of our debt is accelerated, we may not have sufficient funds available to repay such debt. 

Goodwill and indefinite-lived intangible assets recorded as a result of our acquisitions could become impaired. 

As of December 31, 2016, our combined goodwill and indefinite-lived intangible assets amounted to $1.82 billion. To the 
extent we do not generate sufficient cash flows to recover the net amount of any investments in goodwill and other indefinite-
lived intangible assets recorded, the investment could be considered impaired and subject to write-off. We expect to record 

12

further goodwill and other indefinite-lived intangible assets as a result of future acquisitions we may complete. Future 
amortization of such assets or impairments, if any, of goodwill or indefinite-lived intangible assets would adversely affect our 
results of operations in any given period. 

There is a risk that the market value of our common stock may decline. 

Stock markets have experienced significant price and trading volume fluctuations, and the market prices of companies in 
our industry have been volatile. In recent years, volatility and disruption reached unprecedented levels. For some issuers, the 
markets have exerted downward pressure on stock prices and credit capacity. It is impossible to predict whether the price of our 
common stock will rise or fall. Trading prices of our common stock will be influenced by our operating results and prospects 
and by economic, political, financial and other factors.

Item 3. Legal Proceedings.

From time to time, a number of lawsuits and claims have been or may be asserted against us relating to the conduct of our 
business, including routine litigation relating to commercial and employment matters. The outcome of any litigation cannot be 
predicted with certainty, and some lawsuits may be determined adversely to us. However, management does not believe that the 
ultimate outcome of any such pending matters is likely to have a material adverse effect on our financial condition or liquidity, 
although the resolution in any fiscal period of one or more of these matters may have a material adverse effect on our results of 
operations for that period.

Market, Stockholder and Dividend Information. Our common stock is listed on the New York Stock Exchange under the 
symbol “WCC.” As of February 21, 2017, there were 48,720,648 shares of common stock outstanding held by approximately 
22 holders of record. We have not paid dividends on the common stock and do not currently plan to pay dividends. We do, 
however, evaluate the possibility from time to time. It is currently expected that earnings will be reinvested to support business 
growth, debt reduction, acquisitions and share repurchases. In addition, our Revolving Credit Facility and Term Loan Facility 
limit our ability to pay dividends. Furthermore, the 2021 Notes and 2024 Notes limit our ability to pay dividends and 
repurchase our common stock. See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results 
of Operations — Liquidity and Capital Resources.”

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 in Item 8 of this Annual Report on Form 10-K.

Company Overview

In 2016, we took actions to further streamline our organization, simplified our capital structure by redeeming the 6.0% 
Convertible Senior Debentures due 2029 (the "2029 Debentures"), improved productivity, integrated one accretive acquisition, 
generated strong cash flow and closely managed costs. Our financial results primarily reflect challenging economic and end 
market conditions, partially offset by the benefits of cost reduction actions and discretionary spending controls. Sales decreased 
$182.5 million, or 2.4%, over the prior year. Acquisitions and number of workdays positively impacted net sales by 3.1% and 
0.4%, respectively, and were partially offset by a 1.0% decrease in foreign exchange rates, resulting in a 4.9% decrease in 
normalized organic sales. Cost of goods sold as a percentage of net sales was 80.3% and 80.1% in 2016 and 2015, respectively. 
Operating income was $332.0 million for 2016, compared to $373.7 million for 2015. Operating income decreased due to 
lower sales and gross margin, despite actions to reduce operating costs. Net income attributable to WESCO International of 
$101.6 million decreased by 51.8%. Diluted earnings per share attributable to WESCO International was $2.10 in 2016, based 
on 48.3 million diluted shares, compared with diluted earnings per share of $4.18 in 2015, based on 50.4 million diluted shares. 
Excluding the non-cash impact of the convertible debt conversion in the third quarter of $1.70, adjusted earnings per diluted 
share for 2016 was $3.80.

Our end markets consist of industrial firms, electrical and data communications contractors, utilities, and commercial 
organizations, institutions and government entities. Our transaction types to these markets can be categorized as stock, direct 
ship and special order. Stock orders are filled directly from existing inventory and represent approximately 50% of total sales. 
Approximately 39% of our 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 remaining 11% of total sales.

We have historically financed our working capital requirements, capital expenditures, acquisitions, share repurchases and 
new branch openings through internally generated cash flow, debt issuances, borrowings under our Revolving Credit Facility 
and funding through our Receivables Facility.

Cash Flow

We generated $300.2 million in operating cash flow during 2016. Cash provided by operating activities included net income 
of $101.1 million, adjustments to net income totaling $159.3 million, including a loss on the redemption of our convertible debt 
of $123.9 million, and changes in assets and liabilities of $39.8 million. Investing activities included net payments of $50.9 
million, primarily for the acquisition of Atlanta Electrical Distributors, LLC, and capital expenditures of $18.0 million. 
Financing activities consisted of borrowings and repayments of $1.03 billion and $1.10 billion, respectively, related to our 
Revolving Credit Facility, borrowings and repayments of $706.9 million and $851.9 million, respectively, related to our 
Receivables Facility, proceeds from the issuance of the 2024 Notes of $350.0 million, a payment of $344.8 million to redeem 
the 2029 Debentures and repayments of $30.0 million applied to our Term Loan Facility. Financing activities in 2016 also 
included borrowings and repayments on our various international lines of credit of $111.5 million and $131.5 million, 
respectively.  

Free cash flow for the years ended December 31, 2016 and 2015 was $282.2 million and $261.4 million, respectively.

The following table sets forth the components of free cash flow:

Note: The table above reconciles cash flow provided by operations to free cash flow. Free cash flow is a non-GAAP financial measure 
provided by the Company as an additional liquidity measure. Capital expenditures are deducted from operating cash flow to
determine free cash flow. Free cash flow is available to fund the Company's other investing and financing activities.

Financing Availability

As of December 31, 2016, we had $509.7 million in total available borrowing capacity under our Revolving Credit Facility, 

which was comprised of $301.3 million of availability under the U.S. sub-facility and $208.4 million of availability under the 
Canadian sub-facility. Available borrowing capacity under our Receivables Facility was $146.8 million. The Receivables 
Facility and Revolving Credit Facility mature in September 2018 and September 2020, respectively. 

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial 

statements, which have been prepared in accordance with accounting principles generally accepted in the United States of 
America (GAAP). The preparation of these financial statements requires us 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 
ongoing basis, we evaluate our estimates, including those related to supplier programs, bad debts, inventories, insurance costs, 
goodwill, income taxes, contingencies and litigation. We base our 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. We believe the following critical accounting policies affect our judgments and 
estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

Revenues are recognized for product sales when title, ownership and risk of loss pass to the customer or for services when 
the service is rendered. In the case of stock sales and special orders, a sale occurs at the time of shipment from our distribution 
point, as the terms of our sales are typically FOB shipping point. In cases where we process customer orders but ships directly 
from its suppliers, revenue is recognized once product is shipped and title has passed. In all cases, revenue is recognized once 
the sales price to our customer is fixed or is determinable and we have reasonable assurance as to the collectability. 

In certain customer arrangements, we provide services such as inventory management. We may perform some or all of the 

following services for customers: determine inventory stocking levels; establish inventory reorder points; launch purchase 
orders; receive material; pack away material; and pick material for order fulfillment. We recognize revenue for services 
rendered during the period based upon a previously negotiated fee arrangement. We also sell inventory to these customers and 
recognize revenue at the time title and risk of loss transfers to the customer. 

Selling, General and Administrative Expenses

We include warehousing, purchasing, branch operations, information services, and marketing and selling expenses in this 

category, as well as other types of general and administrative costs.

Allowance for Doubtful Accounts

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make 
required payments. We have a systematic procedure using estimates based on historical data and reasonable assumptions of 
collectability made at the local branch level and on a consolidated corporate basis to calculate the allowance for doubtful 
accounts. 

Excess and Obsolete Inventory                                                                                                                                                                                                                          

We write down our inventory to lower of cost and net realizable value based on internal factors derived from historical 
analysis of actual losses. Retrospectively, we identify items in excess of 36 months supply relative to demand or movement. We 
then analyze the ultimate disposition of previously identified excess inventory items as they are sold, returned to supplier, or 
scrapped. This historical item-by-item analysis allows us to develop an estimate of the likelihood that an item identified as 
being in excess supply ultimately becomes obsolete. We apply the estimate to inventory items currently in excess of 36 months 
supply, and reduce our inventory carrying value by the derived amount. We revisit and test our assumptions on a periodic basis. 
Historically, we have not had material changes to our assumptions, nor do we anticipate any material changes in the future.  

19

Supplier Volume Rebates

We receive rebates from certain suppliers based on contractual arrangements with them. Since there is a lag between actual 
purchases and the rebates received from the suppliers, we estimate and accrue the approximate amount of rebates available at a 
specific date. We record the amounts as other accounts receivable in the Consolidated Balance Sheets. The corresponding 
rebate income is derived from the level of actual purchases made by us and is recorded as a reduction of cost of goods sold. 
Supplier volume rebate rates have historically ranged between approximately 0.9% and 1.4% of sales depending on market 
conditions. In 2016, the rebate rate was 1.3%.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill and indefinite-lived intangible assets are tested for impairment annually during the fourth quarter using 

information available at the end of September, or more frequently if triggering events occur indicating that their carrying value 
may not be recoverable. We test for goodwill impairment on a reporting unit level and the evaluation involves comparing the 
fair value of each reporting unit with its carrying value. The fair values of the reporting units are determined using a 
combination of a discounted cash flow analysis and market multiples. Assumptions used for these fair value techniques are 
based on a combination of historical results, current forecasts, market data and recent economic events. We evaluate the 
recoverability of indefinite-lived intangible assets using the relief-from-royalty method based on projected financial 
information. The determination of fair value involves significant management judgment and we apply our best judgment when 
assessing the reasonableness of financial projections. At December 31, 2016 and 2015, goodwill and indefinite-lived 
trademarks totaled $1.82 billion and $1.77 billion, respectively. 

A possible indicator of goodwill impairment is the relationship of a company’s market capitalization to its book value. As of 

December 31, 2016, our market capitalization exceeded our book value and there were no impairment losses identified as a 
result of our annual test. Fair value determinations require considerable judgment and are sensitive to changes in underlying 
assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the 
annual goodwill and indefinite-lived intangible impairment tests will prove to be an accurate prediction of future results. 

Intangible Assets

We account for certain economic benefits purchased as a result of our acquisitions, including customer relations, 

distribution agreements, technology and trademarks, as intangible assets. Most trademarks have an indefinite life. We amortize 
all other intangible assets over a useful life determined by the expected cash flows produced by such intangibles and their 
respective tax benefits. Useful lives vary between 2 and 20 years, depending on the specific intangible asset.

Insurance Programs

We use commercial insurance for auto, workers’ compensation, casualty and health claims as a risk sharing strategy to 
reduce our exposure to catastrophic losses. Our strategy involves large deductible policies where we must pay all costs up to 
the deductible amount. We estimate our reserve based on historical incident rates and costs.

Income Taxes

We account for income taxes under the asset and liability method, which requires the recognition of deferred income taxes 

for events that have future tax consequences. Under this method, deferred income taxes are recognized (using enacted tax 
laws and rates) based on the future income tax effects of differences in the carrying amounts of assets and liabilities for 
financial reporting and tax purposes. The effect of a tax rate change on deferred tax assets and liabilities is recognized in 
income in the period of change.

We recognize deferred tax assets at amounts that are expected to be realized. To make such determination, we evaluate all 
positive and negative evidence, including but not limited to, prior, current and future taxable income, tax planning strategies 
and future reversals of existing temporary differences. A valuation allowance is recognized if it is “more-likely-than-not” that 
some or all of a deferred tax asset will not be realized. We regularly assess the realizability of deferred tax assets.

No provision is made for undistributed earnings that are considered to be permanently reinvested to fund growth in foreign 

markets.

We account for uncertainty in income taxes using a "more-likely-than-not" recognition threshold. Due to the subjectivity 

inherent in the evaluation of uncertain tax positions, the tax benefit ultimately recognized may materially differ from our 
estimate. We recognize interest and penalties related to uncertain tax benefits as part of interest expense and income tax 
expense, respectively.  

Convertible Debentures

We separately accounted for the liability and equity components of the 2029 Debentures in a manner that reflected our non-

convertible debt borrowing rate. We estimated our non-convertible debt borrowing rate through a combination of discussions 

20

with our financial institutions and review of relevant market data. The discounts to the convertible debt balances were 
amortized to interest expense, using the effective interest method, over the implicit life of the debentures.

     Stock-Based Compensation

Our stock-based employee compensation plans are comprised of stock-settled stock appreciation rights, restricted stock 
units, and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date of 
grant, and compensation cost is recognized, net of forfeitures, over the service period for awards expected to vest. The fair 
value of stock-settled appreciation rights and performance-based awards with market conditions is determined using the Black-
Scholes and Monte Carlo simulation models, respectively. The fair value of restricted stock units with service conditions and 
performance-based awards with performance conditions is determined by the grant-date closing price of WESCO's common 
stock. Expected volatilities are based on historical volatility of our common stock. We estimate the expected life of stock-
settled stock appreciation rights using historical data pertaining to option exercises and employee terminations. The risk-free 
rate is based on the U.S. Treasury yields in effect at the time of grant. The forfeiture assumption is based on our historical 
employee behavior, which we review on an annual basis. No dividends are assumed for stock-based awards.

Net Sales. Net sales in 2016 decreased 2.4% to $7.34 billion, compared with $7.52 billion in 2015. Acquisitions and number 

of workdays positively impacted net sales by 3.1% and 0.4%, respectively, and were partially offset by a 1.0% decrease in 
foreign exchange rates, resulting in a 4.9% decrease in normalized organic sales.

The following table sets forth the normalized organic sales change:

Note: Normalized organic sales change is a non-GAAP financial measure provided by the Company to better understand the Company's 
organic sales trends. Normalized organic sales change is calculated by deducting the percentage impact from acquisitions in the first year 
of ownership, foreign exchange rates and number of workdays from the overall percentage change in consolidated net sales.

Cost of Goods Sold. Cost of goods sold decreased 2.3% in 2016 to $5.89 billion, compared with $6.02 billion in 2015. Cost 

of goods sold as a percentage of net sales was 80.3% and 80.1% in 2016 and 2015, respectively. 

Selling, General and Administrative (“SG&A”) Expenses. SG&A expenses include costs associated with personnel, 
shipping and handling, travel, advertising, facilities, utilities and bad debts. SG&A expenses decreased by $5.7 million, or 

21

0.5%, to $1.05 billion in 2016. SG&A expenses decreased as the cost impact of recent acquisitions was offset by savings from 
headcount reductions, branch closures and consolidations, and ongoing discretionary spending cost controls. As a percentage of 
net sales, SG&A expenses increased to 14.3% in 2016, compared to 14.0% in 2015, reflecting lower sales volume.

SG&A payroll expenses for 2016 of $734.8 million decreased by $1.1 million compared to 2015. The decrease in SG&A 

payroll expenses was primarily due to a decrease in commissions, incentives and benefits.

The remaining SG&A expenses for 2016 of $314.5 million decreased by $4.6 million compared to 2015.  

Depreciation and Amortization. Depreciation and amortization increased $1.9 million to $66.9 million in 2016, compared 

with $65.0 million in 2015. 

Income from Operations. Income from operations decreased by $41.7 million to $332.0 million in 2016, compared to 

$373.7 million in 2015. Income from operations as a percentage of net sales was 4.5% and 5.0% in 2016 and 2015, 
respectively. Income from operations as a percentage of net sales decreased as the benefits resulting from cost management 
were offset by lower sales and gross margin.

Interest Expense. Interest expense totaled $76.6 million in 2016, compared with $69.8 million in 2015, an increase of 9.7%. 

Non-cash interest expense, which includes the amortization of debt discounts and debt issuance costs, and interest related to 
uncertain tax positions, was $7.9 million and $3.5 million for 2016 and 2015, respectively. In the fourth quarter of 2015, the 
resolution of transfer pricing matters associated with previously filed tax positions resulted in non-cash interest income of $9.4 
million.

Loss on Debt Redemption. Loss on debt redemption of $123.9 million was the result of a non-cash charge from the early 

redemption of the 2029 Debentures in the third quarter of 2016.

Income Taxes. Our effective tax rate was 23.1% in 2016 compared to 31.4% in 2015. Our effective tax rate is affected by 
recurring items, such as the relative amounts of income earned in the United States and foreign jurisdictions, primarily Canada, 
the tax rates in these jurisdictions and changes in foreign currency exchange rates. The loss on debt redemption reduced income 
before income taxes, which decreased the effective tax rate for 2016. In 2015, the resolution of the transfer pricing matter 
described above resulted in incremental income tax expense, which increased the effective tax rate.

Net Income. Net income decreased by $107.3 million, or 51.5%, to $101.1 million in 2016, compared to $208.4 million in 

2015. Adjusted net income for the year ended December 31, 2016 was $183.8 million.

Net Loss Attributable to Noncontrolling Interests. Net loss attributable to noncontrolling interests was $0.5 million in 2016, 
compared to $2.3 million in 2015. The losses in 2016 and 2015 were primarily due to foreign exchange losses on cash balances. 

Net Income Attributable to WESCO International. Net income and diluted earnings per share attributable to WESCO 
International were $101.6 million and $2.10 per share, respectively, in 2016, compared with $210.7 million and $4.18 per 
share, respectively, in 2015. Adjusted net income and diluted earnings per share attributable to WESCO International were 
$184.3 million and $3.80 per share, respectively, for the year ended December 31, 2016.

(1)  Represents the third quarter of 2016 income tax benefit related to the loss on debt redemption.

(2)  The loss on debt redemption and related income tax benefit are based on the third quarter of 2016 diluted shares of 48.7 million.

Note: Adjusted net income attributable to WESCO International, Inc. is defined as income before income taxes plus the third quarter loss 
on debt redemption, less the provision for income taxes excluding the third quarter benefit of such loss. Adjusted earnings per diluted 
share is computed by adding the loss per diluted share on debt redemption and deducting the related income tax benefit per diluted share 
recognized in the third quarter of 2016. The Company believes that these non-GAAP financial measures provide an overall understanding 
of the Company's current financial performance and a consistent measure for assessing the current and historical financial results.

2015 Compared to 2014 

Net Sales. Net sales in 2015 decreased 4.7% to $7.52 billion, compared with $7.89 billion in 2014. Normalized organic sales 

decreased 3.3%; foreign exchange rates negatively impacted sales by 3.4% and were partially offset by a positive impact from 
acquisitions of 2.0%. Additionally, management estimates that price had no measurable impact on net sales.

Note: Normalized organic sales change is a non-GAAP financial measure provided by the Company to better understand the Company's 
organic sales trends. Normalized organic sales change is calculated by deducting the percentage impact from acquisitions in the first year 
of ownership, foreign exchange rates and number of workdays from the overall percentage change in consolidated net sales.

Cost of Goods Sold. Cost of goods sold decreased 4.0% in 2015 to $6.02 billion, compared with $6.28 billion in 2014. Cost 

of goods sold as a percentage of net sales was 80.1% and 79.6% in 2015 and 2014, respectively. 

Selling, General and Administrative (“SG&A”) Expenses. SG&A expenses include costs associated with personnel, 
shipping and handling, travel, advertising, facilities, utilities and bad debts. SG&A expenses decreased by $21.9 million, or 
2.0%, to $1.06 billion in 2015. The decrease in SG&A expenses is primarily due to cost reduction actions implemented during 
2015, foreign exchange rates, lower variable sales and compensation costs and ongoing discretionary spending controls. As a 
percentage of net sales, SG&A expenses increased to 14.0% in 2015, compared to 13.6% in 2014, reflecting lower sales 
volume and incremental costs related to recent acquisitions, which were not fully offset by cost control actions and initiatives.

SG&A payroll expenses for 2015 of $735.9 million decreased by $23.0 million compared to 2014. The decrease in SG&A 

payroll expenses was primarily due to a decrease in commissions, incentives and benefits of $16.6 million and a decrease in 
temporary labor of $4.7 million. These decreases were due to a 5% headcount reduction, exclusive of acquisitions, and a 
reduction in discretionary spending. 

The remaining SG&A expenses for 2015 of $319.1 million increased by $1.2 million compared to 2014.  

Depreciation and Amortization. Depreciation and amortization decreased $3.0 million to $65.0 million in 2015, compared 

with $68.0 million in 2014. 

Income from Operations. Income from operations decreased by $92.5 million to $373.7 million in 2015, compared to 

$466.2 million in 2014. Income from operations as a percentage of net sales was 5.0% and 5.9% in 2015 and 2014, 
respectively.

Interest Expense. Interest expense totaled $69.8 million in 2015, compared with $82.1 million in 2014, a decrease of 14.9%. 

Non-cash interest expense, which includes the amortization of debt discounts and debt issuance costs, and interest related to 
uncertain tax positions, was $3.5 million and $9.5 million for 2015 and 2014, respectively. The resolution of transfer pricing 
matters associated with previously filed tax positions resulted in non-cash interest income of $9.4 million in the fourth quarter 
of 2015. Cash interest expense decreased primarily as a result of the repayment of the Canadian sub-facility of the term loans 
due 2019 throughout 2015.

Income Taxes. Our effective tax rate was 31.4% in 2015 compared to 28.3% in 2014. Our effective tax rate is affected by 
recurring items, such as the relative amounts of income earned in the United States and foreign jurisdictions, primarily Canada, 
the tax rates in these jurisdictions and changes in foreign currency exchange rates. The resolution of the tax matter described 
above in the discussion of interest expense resulted in incremental income tax expense of $11.7 million, which increased the 
effective tax rate by 2.9 percentage points.

Net Income. Net income decreased by $67.1 million, or 24.3%, to $208.4 million in 2015, compared to $275.4 million in 

2014. 

Net Loss Attributable to Noncontrolling Interests. Net loss attributable to noncontrolling interests was $2.3 million in 2015, 
compared to $0.5 million in 2014. The losses in 2015 and 2014 were primarily due to foreign exchange losses on cash balances. 

Net Income Attributable to WESCO International. Net income and diluted earnings per share attributable to WESCO 
International were $210.7 million and $4.18 per share, respectively, in 2015, compared with $275.9 million and $5.18 per 
share, respectively, in 2014.

Liquidity and Capital Resources

Total assets were $4.49 billion and $4.57 billion at December 31, 2016 and 2015, respectively. Total liabilities at 

December 31, 2016 and 2015 were $2.48 billion and $2.80 billion, respectively. Stockholders’ equity increased by 13.3% to 
$2.01 billion at December 31, 2016, compared with $1.77 billion at December 31, 2015, primarily as a result of net income of 
$101.6 million, the redemption of the 2029 Debentures, which excluding the loss, had a positive net impact on equity of $93.6 
million, and foreign currency translation adjustments of $38.3 million.

Our liquidity needs generally arise from fluctuations in our working capital requirements, capital expenditures, acquisitions 

and debt service obligations. As of December 31, 2016, we had $509.7 million in available borrowing capacity under our 
Revolving Credit Facility and $146.8 million in available borrowing capacity under our Receivables Facility, which combined 
with available cash of $48.1 million, provided liquidity of $704.6 million. Cash included in our determination of liquidity 
represents cash in deposit and interest bearing investment accounts. We believe cash provided by operations and financing 
activities will be adequate to cover our current operational and business needs.

We monitor the depository institutions that hold our cash and cash equivalents on a regular basis, and we believe that we 

have placed our deposits with creditworthy financial institutions. We also communicate on a regular basis with our lenders 
regarding our financial and working capital performance, liquidity position and financial leverage. Our financial leverage ratio 
was 3.5 and 3.8 as of December 31, 2016 and 2015, respectively. In addition, we are in compliance with all covenants and 
restrictions contained in our debt agreements as of December 31, 2016.

(1)  Long-term debt is presented in the condensed consolidated balance sheets net of deferred financing fees and debt discount.

Note: Financial leverage is a non-GAAP financial measure provided by the Company to illustrate its capital structure position. Financial 
leverage ratio is calculated by dividing total debt, including debt discount and deferred financing fees, by adjusted EBITDA. Adjusted 
EBITDA is defined as the trailing twelve months earnings before interest, taxes, depreciation and amortization, plus loss on debt redemption.

At December 31, 2016, we had cash and cash equivalents totaling $110.1 million, of which $76.4 million was held by 
foreign subsidiaries. The cash held by some of our foreign subsidiaries could be subject to additional U.S. income taxes if 
repatriated. We believe that we are able to maintain a sufficient level of liquidity for our domestic operations and commitments 
without repatriation of the cash held by these foreign subsidiaries.

Over the next several quarters, we plan to closely manage working capital, and it is expected that excess cash will be 

directed primarily at debt reduction, acquisitions and share repurchases. We remain focused on maintaining ample liquidity and 
credit availability. We anticipate capital expenditures in 2017 to be at levels similar to 2016. We believe our balance sheet and 
ability to generate ample cash flow provides us with a durable business model and should allow us to fund expansion needs and 
growth initiatives.

We finance our operating and investing needs as follows:

Accounts Receivable Securitization Facility

On September 24, 2015, WESCO Distribution amended and restated its accounts receivable securitization facility (the 

"Receivables Facility") pursuant to the terms and conditions of a Fourth Amended and Restated Receivables Purchase 
Agreement (the “Receivables Purchase Agreement”), by and among WESCO Receivables Corp. (“WESCO Receivables”), 
WESCO Distribution, the various purchaser groups from time to time party thereto and PNC Bank, National Association, as 
Administrator. The Receivables Purchase Agreement amended and restated the receivables purchase agreement entered into on 
April 13, 2009.  

The Receivables Purchase Agreement increased the purchase limit from $500 million to $550 million, with the opportunity 

to exercise an accordion feature which permits increases in the purchase limit of up to $100 million, extended the term of the 
Receivables Facility to September 24, 2018 and added and amended certain defined terms. The interest rate spread and 
commitment fee of the Receivables Facility remained at 0.95% and 0.45%, respectively. 

Under the Receivables Facility, WESCO sells, on a continuous basis, an undivided interest in all domestic accounts 
receivable to WESCO Receivables, a wholly owned special purpose entity (the “SPE”). The SPE sells, without recourse, a 
senior undivided interest in the receivables to financial institutions for cash while maintaining a subordinated undivided interest 
in the receivables, in the form of overcollateralization. WESCO has agreed to continue servicing the sold receivables for the 
third-party conduits and financial institutions at market rates; accordingly, no servicing asset or liability has been recorded.

27

As of December 31, 2016 and 2015, accounts receivable eligible for securitization totaled approximately $657.5 million and 

$684.7 million, respectively. The Consolidated Balance Sheets as of December 31, 2016 and 2015 include $380.0 million and 
$525.0 million, respectively, of account receivable balances legally sold to third parties, as well as borrowings for equal 
amounts. At December 31, 2016, the interest rate on borrowings under this facility was approximately 1.4%.

Revolving Credit Facility

On September 24, 2015, WESCO International, WESCO Distribution and certain other subsidiaries of the Company entered 
into a $600 million revolving credit facility (the “Revolving Credit Facility”), which contains a letter of credit sub-facility of up 
to $125 million, pursuant to the terms and conditions of a Second Amended and Restated Credit Agreement (the "Credit 
Agreement"). The Revolving Credit Facility contains an accordion feature allowing WESCO Distribution to request increases 
to the borrowing commitments, subject to customary conditions. This accordion feature increased from $100 million to $200 
million in the aggregate. The Revolving Credit Facility replaced WESCO Distribution’s prior revolving credit facility entered 
into on December 12, 2012.  

The Revolving Credit Facility matures in September 2020 and consists of two separate sub-facilities: (i) a Canadian sub-
facility with a borrowing limit of up to $400 million, which is collateralized by substantially all assets of WESCO Canada and 
the other Canadian Borrowers, other than, among other things, real property, in each case, subject to customary exceptions and 
limitations, and (ii) a U.S sub-facility with a borrowing limit of up to $600 million less the amount of outstanding borrowings 
under the Canadian sub-facility. The U.S. sub-facility is collateralized by substantially all assets of WESCO Distribution and its 
subsidiaries which are party to the Credit Agreement, other than, among other things, real property and accounts receivable sold 
or intended to be sold pursuant to the Receivables Purchase Agreement. The applicable interest rate for borrowings under the 
Revolving Credit Facility includes interest rate spreads based on available borrowing capacity that range between 1.25% and 
1.75% for LIBOR-based borrowings and 0.25% and 0.75% for prime rate-based borrowings. At December 31, 2016, the 
interest rate on borrowings under this facility was approximately 2.0%. 

The Credit Agreement requires ongoing compliance with certain customary affirmative and negative covenants. The Credit 

Agreement also contains customary events of default. 

During 2016, WESCO borrowed $1,025.8 million under the Revolving Credit Facility and made repayments in the 

aggregate amount of $1,096.8 million. During 2015, aggregate borrowings and repayments were $1,276.0 million and $1,209.0 
million, respectively. WESCO had $509.7 million available under the Revolving Credit facility at December 31, 2016, after 
giving effect to outstanding letters and international lines of credit, as compared to approximately $438.7 million million at 
December 31, 2015.

International Lines of Credit

Certain foreign subsidiaries of WESCO have entered into uncommitted lines of credit, which serve as overdraft facilities, to 

support local operations. The maximum borrowing limit varies by facility and ranges between $0.3 million and $21.0 million. 
The applicable interest rate for borrowings under these lines of credit varies by country and is governed by the applicable loan 
agreement. The international lines of credit are renewable on an annual basis and certain facilities are fully and unconditionally 
guaranteed by WESCO Distribution. Accordingly, borrowings under these lines directly reduce availability under the Revolving 
Credit Facility.

Term Loan Facility 

On December 12, 2012, WESCO Distribution, as U.S. borrower, WDCC Enterprises Inc. ("WDCC" and together with 

WESCO Distribution, the “Borrowers”), as Canadian borrower, and WESCO International entered into a Term Loan Agreement 
(the “Term Loan Agreement”) among WESCO Distribution, WDCC, the Company, the lenders party thereto and Credit Suisse 
AG Cayman Islands Branch, as administrative agent and as collateral agent. 

The Term Loan Agreement provided a seven-year term loan facility (the “Term Loan Facility”), which consisted of two 

separate sub-facilities: (i) a Canadian sub-facility in an aggregate principal amount of CAD150 million, issued at a 2.0% 
discount, and (ii) a U.S. sub-facility in an aggregate principal amount of $700 million, issued at a 1.0% discount. The proceeds 
of the Term Loan Facility were used to finance the acquisition of EECOL, and to pay fees and expenses incurred in connection 
with the acquisition and certain other transactions. Subject to the terms of the Term Loan Agreement, the Borrowers may 
request incremental term loans from time to time in an aggregate principal amount not to exceed at any time $300 million, with 
an equivalent principal amount in U.S. dollars being calculated for any incremental term loan denominated in Canadian dollars.  

On November 19, 2013, the Borrowers and WESCO International entered into an amendment (the “Term Loan 

Amendment”) to the Term Loan Agreement. The Term Loan Amendment, among other things, reduced the applicable margin 
on U.S. term loans by 0.50% and the LIBOR floor applicable to the U.S. sub-facility from 1.00% to 0.75%. The modified 
pricing terms were effective December 13, 2013.

28

On November 26, 2013, WESCO Distribution sold $500 million aggregate principal amount of 5.375% Senior Notes due 

2021 (the “2021 Notes”), and used the net proceeds plus excess cash to prepay $500 million under the Company's U.S. sub-
facility of the Term Loan Facility (see discussion below under “5.375% Senior Notes due 2021” for additional information). 
The prepayment satisfied all remaining quarterly repayment obligations under the U.S. sub-facility. As of December 31, 2016, 
the amount outstanding under the U.S. sub-facility was $144.8 million. The Canadian sub-facility was fully repaid in 2015 
using cash provided by Canadian operations.

Borrowings under the Term Loan Facility bear interest at base rates plus applicable margins. At December 31, 2016, the 
interest rate on borrowings under the U.S. sub-facility was 4.0%. To the extent not previously paid, the outstanding U.S. sub-
facility will become due and payable on December 12, 2019, with any unpaid incremental term loans becoming due and 
payable on the respective maturity dates applicable to those incremental term loans. At any time or from time to time, the 
Borrowers may prepay borrowings under the Term Loan Facility in whole or in part without premium or penalty. The 
Borrowers' obligations under the Term Loan Facility are secured by substantially all of the assets of the Borrowers, the 
Company and certain of the Company's other subsidiaries; provided that, with respect to borrowings under the U.S. sub-facility, 
the collateral does not include assets of certain foreign subsidiaries or more than 65% of the issued and outstanding equity 
interests in certain foreign subsidiaries. 

The Term Loan Facility contains customary affirmative and negative covenants for credit facilities of this type. The Term 

Loan Facility also provides for customary events of default.

5.375% Senior Notes due 2021

In November 2013, WESCO Distribution issued $500 million aggregate principal amount of  2021 Notes through a private 
offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The 2021 
Notes were issued at 100% of par and are governed by an indenture (the “2021 Indenture”) entered into on November 26, 2013 
with WESCO International and U.S. Bank National Association, as trustee. The 2021 Notes are unsecured senior obligations of 
WESCO Distribution and are guaranteed on a senior unsecured basis by WESCO International. The 2021 Notes bear interest at 
a stated rate of 5.375%, payable semi-annually in arrears on June 15 and December 15 of each year. In addition, we incurred 
costs related to the issuance of the 2021 Notes totaling $8.4 million, which are recorded as a reduction to the carrying value of 
the debt and are being amortized over the life of the notes. The 2021 Notes mature on December 15, 2021. The net proceeds of 
the 2021 Notes were used to prepay a portion of the U.S. sub-facility of the term loans due 2019. 

Under the terms of a registration rights agreement dated as of November 26, 2013 among WESCO Distribution, WESCO 
International and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as the representative of the initial purchasers of the 2021 
Notes, WESCO Distribution and WESCO International agreed to register under the Securities Act notes having terms identical 
in all material respects to the 2021 Notes (the “2021 Exchange Notes”) and to make an offer to exchange the 2021 Exchange 
Notes for the 2021 Notes. WESCO Distribution launched the exchange offer on June 12, 2014 and the exchange offer expired 
on July 17, 2014.   

At any time on or after December 15, 2016, WESCO Distribution may redeem all or a part of the 2021 Notes. Between 
December 15, 2016 and December 14, 2017, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption 
price equal to 104.031% of the principal amount. Between December 15, 2017 and December 14, 2018, WESCO Distribution 
may redeem all or a part of the 2021 Notes at a redemption price equal to 102.688% of the principal amount. Between 
December 15, 2018 and December 14, 2019, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption 
price equal to 101.344% of the principal amount. On and after December 15, 2019, WESCO Distribution may redeem all or a 
part of the 2021 Notes at a redemption price equal to 100% of the principal amount.

The 2021 Indenture contains customary covenants and customary events of default. In addition, upon a change of control, 

the holders of 2021 Notes have the right to require WESCO Distribution to repurchase all or any part of the 2021 Notes at a 
redemption price equal to 101% of the principal amount, plus accrued and unpaid interest.  

5.375% Senior Notes due 2024 

In June 2016, WESCO Distribution issued $350 million aggregate principal amount of 5.375% Senior Notes due 2024 (the 
"2024 Notes") through a private offering exempt from the registration requirements of the Securities Act. The 2024 Notes were 
issued at 100% of par and are governed by an indenture (the “2024 Indenture”) entered into on June 15, 2016 among WESCO 
Distribution, as issuer, WESCO International, as parent guarantor, and U.S. Bank National Association, as trustee. The 2024 
Notes are unsecured senior obligations of WESCO Distribution and are guaranteed on a senior unsecured basis by WESCO 
International. The 2024 Notes bear interest at a rate of 5.375% per annum, payable semi-annually in arrears on June 15 and 
December 15 of each year, commencing on December 15, 2016. We incurred costs totaling $6.0 million to issue the 2024 
Notes, which are recorded as a reduction to the carrying value of the debt and are being amortized over the life of the note. The 
notes mature on June 15, 2024. The Company used the net proceeds to redeem its 2029 Debentures on September 15, 2016.

29

Under the terms of a registration rights agreement dated as of June 15, 2016 among WESCO Distribution, as the issuer, 
WESCO International, as parent guarantor, and Goldman, Sachs & Co., as representative of the initial purchasers of the 2024 
Notes, WESCO Distribution and WESCO International agreed to register under the Securities Act notes having terms identical 
in all material respects to the 2024 Notes (the “2024 Exchange Notes”) and to make an offer to exchange the 2024 Exchange 
Notes for the 2024 Notes. WESCO Distribution launched the exchange offer on December 28, 2016 and the exchange offer 
expired on January 31, 2017. 

At any time on or after June 15, 2019, WESCO Distribution may redeem all or a part of the 2024 Notes. Between June 15, 

2019 and June 14, 2020, WESCO Distribution may redeem all or a part of the 2024 Notes at a redemption price equal to 
104.031% of the principal amount. Between June 15, 2020 and June 14, 2021, WESCO Distribution may redeem all or a part of 
the 2024 Notes at a redemption price equal to 102.688% of the principal amount. Between June 15, 2021 and June 14, 2022, 
WESCO Distribution may redeem all or a part of the 2024 Notes at a redemption price equal to 101.344% of the principal 
amount. On and after June 15, 2022, WESCO Distribution may redeem all or a part of the 2024 Notes at a redemption price 
equal to 100% of the principal amount.    

The 2024 Indenture contains customary covenants and events of default. Upon a change of control, the holders of the 2024 
Notes have the right to require WESCO Distribution to repurchase all or any part of the 2024 Notes at a redemption price equal 
to 101% of the principal amount thereof, plus accrued and unpaid interest.

6.0% Convertible Senior Debentures due 2029

On August 27, 2009, WESCO International completed an exchange offer pursuant to which it issued $345 million in 
aggregate principal amount of the 2029 Debentures. The 2029 Debentures were issued pursuant to an Indenture dated August 
27, 2009, with The Bank of New York Mellon, as trustee, and were unconditionally guaranteed on an unsecured senior 
subordinate basis by WESCO Distribution. 

We separately accounted for the liability and equity components of the 2029 Debentures in a manner that reflected our non-

convertible debt borrowing rate. We utilized an interest rate of 13.875% to reflect the non-convertible debt borrowing rate of 
our offering upon issuance, which was determined based on discussions with our financial institutions and a review of relevant 
market data, and resulted in a $181.2 million discount to the 2029 Debenture balance and a net increase in additional capital of 
$106.5 million. As of December 31, 2015, the net equity included in additional capital related to the 2029 Debentures totaled 
$106.3 million. In addition, the financing costs incurred to issue the 2029 Debentures were allocated between the instrument's 
debt and equity components. We amortized the discount and financing costs over the life of the debt. For the years ended 
December 31, 2016, 2015 and 2014, non-cash interest expense for the amortization of the debt discount and debt issuance costs 
was $3.1 million, $4.2 million and $3.8 million, respectively.

On September 15, 2016, we redeemed the 2029 Debentures. Holders of the 2029 Debentures received cash totaling $344.8 
million, which was equal to the principal amount of the then-outstanding Debentures, in addition to accrued and unpaid interest.  
Holders who surrendered the 2029 Debentures for conversion received 18 shares of our stock for each $1,000 principal amount 
of 2029 Debentures converted. In total, 6,267,688 shares were issued on the redemption date. The redemption resulted in a non-
cash loss of $123.9 million, which included the write off of unamortized discount and debt issuance costs.

Purchase orders for inventory requirements and service contracts are not included in the table above. Generally, our 
purchase orders and contracts contain clauses allowing for cancellation. We do not have significant agreements to purchase 
material or goods that would specify minimum order quantities. Also, we do not consider liabilities for uncertain tax benefits to 
be contractual obligations requiring disclosure due to the uncertainty surrounding the ultimate settlement and timing of these 
liabilities. As such, we have not included liabilities for uncertain tax benefits of $7.0 million in the table above.

Inflation

The rate of inflation, as measured by changes in the producer price index, affects different commodities, the cost of products 

purchased and ultimately the pricing of our different products and product classes to our customers. Our pricing related to 
inflation did not have a measurable impact on our sales revenue. Historically, price changes from suppliers have been consistent 
with inflation and have not had a material impact on the results of operations.

Seasonality

Sales during the first quarter are affected by a reduced level of activity. Sales during the second, third and fourth quarters 

are generally 5 - 7% higher than the first quarter. Sales typically increase beginning in March, with slight fluctuations per 
month through October. During periods of economic expansion or contraction our sales by quarter have varied significantly 
from this pattern.

Impact of Recently Issued Accounting Standards

See Note 2 of the Notes to the Consolidated Financial Statements for information regarding the effect of new accounting 

pronouncements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risks.

Foreign Currency Risks

Approximately 23% of our sales in 2016 were made by our foreign subsidiaries located in North America, South America, 

Europe, Africa, and Asia and are denominated in foreign currencies. We may establish additional foreign subsidiaries in the 
future. Accordingly, we may derive a larger portion of our sales from international operations, and a portion of these sales may 
be denominated in foreign currencies. As a result, our future operating results could become subject to fluctuations in foreign 
exchange rates relative to the U.S. dollar. Furthermore, to the extent that we engage in international sales denominated in U.S. 
dollars, an increase in the value of the U.S. dollar relative to foreign currencies could make our products less competitive in 
international markets. We have monitored and will continue to monitor our exposure to currency fluctuations.

Interest Rate Risk

Fixed Rate Borrowings: Approximately 61% of our debt portfolio is comprised of fixed rate debt. At various times, we have 

refinanced our debt to mitigate the impact of interest rate fluctuations. As the 2021 Notes and 2024 Notes were issued at fixed 
rates, interest expense would not be impacted by interest rate fluctuations, although market value would be. For the 2021 Notes 
and 2024 Notes, fair value approximated carrying value (see Note 7 to the Consolidated Financial Statements).

Floating Rate Borrowings: The Company's variable rate borrowings at December 31, 2016 were comprised of the amounts 
outstanding under the Term Loan Facility, Receivables Facility, Revolving Credit Facility, and the international lines of credit. 
The fair value of these debt instruments at December 31, 2016 approximated carrying value. We entered into the Term Loan 
Facility on December 12, 2012 and the proceeds were primarily used to finance the acquisition of EECOL. Borrowings under 
the U.S. sub-facility of the Term Loan Facility bear interest at 0.75% or, if greater, the applicable LIBOR (London Interbank 
Offered Rate) or base rates plus applicable margins and therefore are subject to fluctuations in interest rates. We borrow under 
our Revolving Credit Facility and Receivables Facility for general corporate purposes, including working capital requirements 
and capital expenditures. Borrowings under our Revolving Credit Facility bear interest at the applicable LIBOR / CDOR 
(Canadian Dealer Offered Rate) or base rates plus applicable margins, whereas borrowings under the Receivables Facility bear 
interest at the 30 day LIBOR plus applicable margins. A 100 basis point increase or decrease in interest rates would not have a 
significant impact on future earnings under our current capital structure.

Report of Independent Registered Public Accounting Firm

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

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income and 
comprehensive income (loss), stockholders’ equity and cash flows present fairly, in all material respects, the financial position 
of WESCO International, Inc. and its subsidiaries at December 31, 2016 and 2015, and the results of their operations and their 
cash flows for each of the three years in the period ended December 31, 2016 in conformity with accounting principles 
generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the 
index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in 
conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material 
respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal 
Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(COSO). The Company's management is responsible for these financial statements and financial statement schedule, for 
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over 
financial reporting, included in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. 
Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the 
Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with 
the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and 
perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and 
whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial 
statements included 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. Our audit of internal control over financial reporting included obtaining an understanding of internal 
control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and 
operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other 
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our 
opinions.

As disclosed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for the 
presentation of deferred income taxes and debt issuance costs in 2016.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures 
that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to 
permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION

WESCO International, Inc. ("WESCO International") and its subsidiaries (collectively, “WESCO” or the "Company"), 
headquartered in Pittsburgh, Pennsylvania, is a full-line distributor of electrical, industrial and communications maintenance, 
repair and operating (“MRO”) and original equipment manufacturers (“OEM”) products, construction materials, and advanced 
supply chain management and logistics services used primarily in the industrial, construction, utility and commercial, 
institutional and government markets. We serve approximately 75,000 active customers globally, through approximately 500 
full service branches and nine distribution centers located primarily in the United States, Canada and Mexico, with operations 
in 14 additional countries.

2. ACCOUNTING POLICIES

Basis of Consolidation

The consolidated financial statements include the accounts of WESCO International and all of its subsidiaries. All 

significant intercompany accounts and transactions have been eliminated in consolidation.

Reclassifications

The Consolidated Statement of Cash Flows for the year ended December 31, 2015 and 2014 includes certain 

reclassifications to previously reported amounts to conform to the current period presentation. 

During the first quarter of 2016, the Company adopted certain accounting pronouncements that were effective beginning this 

fiscal year. The adoption of such guidance, as described below, resulted in certain reclassifications to amounts previously 
reported in the Consolidated Balance Sheet at December 31, 2015.

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 for product sales when title, ownership and risk of loss pass to the customer or for services when 

the service is rendered. In the case of stock sales and special orders, a sale occurs at the time of shipment from WESCO's 
distribution point, as the terms of WESCO’s sales are typically FOB shipping point. In cases where WESCO processes 
customer orders but ships directly from its suppliers, revenue is recognized once product is shipped and title has passed. In all 
cases, revenue is recognized once the sales price to the customer is fixed or is determinable and WESCO has reasonable 
assurance as to the collectability. 

In certain customer arrangements, WESCO provides services such as inventory management. WESCO may perform some 
or all of the following services for customers: determine inventory stocking levels; establish inventory reorder points; launch 
purchase orders; receive material; pack away material; and pick material for order fulfillment. WESCO recognizes revenue for 
services rendered during the period based upon a previously negotiated fee arrangement. WESCO also sells inventory to these 
customers and recognizes revenue at the time title and risk of loss transfers to the customer. The amount of revenue attributed to 
these services totaled $27.1 million, $35.1 million, and $31.0 million in 2016, 2015 and 2014, respectively.

Selling, General and Administrative Expenses

WESCO includes warehousing, purchasing, branch operations, information services, and marketing and selling expenses in 

this category, as well as other types of general and administrative costs.

Supplier Volume Rebates

WESCO receives volume rebates from certain suppliers based on contractual arrangements with such suppliers. Volume 
rebates are included within other accounts receivable in the Consolidated Balance Sheets, and represent the estimated amounts 
due to WESCO under the rebate provisions of the various supplier contracts. The corresponding rebate income is derived from 
the level of actual purchases made by WESCO and is recorded as a reduction to cost of goods sold. Receivables under the 
supplier rebate program were $64.2 million at December 31, 2016 and $62.6 million at December 31, 2015. Supplier volume 
rebate rates have historically ranged between approximately 0.9% and 1.4% of sales depending on market conditions. In 2016, 
the rebate rate was 1.3%.

39

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

Shipping and Handling Costs and Fees

WESCO records the costs and fees associated with transporting its products to customers as a component of selling, general 

and administrative expenses. These costs totaled $57.9 million, $59.4 million and $63.6 million in 2016, 2015 and 2014, 
respectively.

Cash Equivalents

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

Asset Securitization

WESCO maintains control of the receivables transferred pursuant to its accounts receivable securitization program (the 

“Receivables Facility”); therefore, the transfers do not qualify for “sale” treatment. As a result, the transferred receivables 
remain on the balance sheet, and WESCO recognizes the related secured borrowing. The expenses associated with the 
Receivables Facility are reported as interest expense in the Consolidated Statements of Income and Comprehensive Income 
(Loss). 

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 collectability made at the local branch level and on a 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 $22.0 million at 
December 31, 2016 and $22.6 million at December 31, 2015. The total amount recorded as selling, general and administrative 
expense related to bad debts was $5.9 million, $6.1 million and $5.9 million for 2016, 2015 and 2014, respectively.

Inventories

Inventories primarily consist of merchandise purchased for resale and are stated at the lower of cost and net realizable 
value. Cost is determined principally under the average cost method. WESCO makes provisions for obsolete or slow-moving 
inventories as necessary to reflect reduction in inventory value. WESCO writes down its inventory to net realizable value based 
on internal factors derived from historical analysis of actual losses. Retrospectively, WESCO identifies items in excess of 36 
months supply relative to demand or movement. WESCO then analyzes the ultimate disposition of previously identified excess 
inventory items as they are sold, returned to supplier, or scrapped. This historical item-by-item analysis allows WESCO to 
develop an estimate of the likelihood that an item identified as being in excess supply ultimately becomes obsolete. WESCO 
applies the estimate to inventory items currently in excess of 36 months supply, and reduces the carrying value of its inventory 
by the derived amount. Reserves for excess and obsolete inventories were $27.3 million and $24.7 million at December 31, 
2016 and 2015, respectively. The total expense related to excess and obsolete inventories, included in cost of goods sold, was 
$7.3 million, $8.6 million and $6.2 million for 2016, 2015 and 2014, respectively. WESCO absorbs into the cost of inventory 
certain overhead expenses related to inventory such as purchasing, receiving and storage and at December 31, 2016 and 2015, 
$65.3 million and $65.0 million, respectively, of these costs were included in ending inventory.

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 leasehold improvements and 
buildings and three to ten years for furniture, fixtures and equipment.

Capitalized computer software costs are amortized using the straight-line method over the estimated useful life, typically 

three to five years, and are reported at the lower of unamortized cost or net realizable value.

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 and reported as selling, general and 
administrative expenses.

Of WESCO’s $157.6 million net book value of property, buildings and equipment as of December 31, 2016, $98.1 million 
consists of land, buildings and leasehold improvements and are geographically dispersed among WESCO’s 500 branches and 
nine distribution centers, mitigating the risk of impairment. WESCO assesses its long-lived assets for impairment whenever 
events or changes in circumstances indicate the carrying amount of any such assets may not be fully recoverable. Changes in 

40

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

circumstances include technological advances, changes in our business model, capital structure, economic conditions or 
operating performance. The evaluation is based upon, among other things, utilization, serviceability and assumptions about the 
estimated future undiscounted cash flows these assets are expected to generate. When the sum of the undiscounted cash flows is 
less than the carrying value of the asset or asset group, WESCO will recognize an impairment loss to the extent that carrying 
value exceeds fair value. Management applies its best judgment when performing these evaluations.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill and indefinite-lived intangible assets are tested for impairment annually during the fourth quarter using 

information available at the end of September, or more frequently if triggering events occur indicating that their carrying value 
may not be recoverable. WESCO tests for goodwill impairment on a reporting unit level and the evaluation involves comparing 
the fair value of each reporting unit to its carrying value. The fair values of the reporting units are determined using a 
combination of a discounted cash flow analysis and market multiples. Assumptions used for these fair value techniques are 
based on a combination of historical results, current forecasts, market data and recent economic events. WESCO evaluates the 
recoverability of indefinite-lived intangible assets using the relief-from-royalty method based on projected financial 
information. The determination of fair value involves significant management judgment and management applies its best 
judgment when assessing the reasonableness of financial projections. At December 31, 2016 and 2015, goodwill and indefinite-
lived trademarks totaled $1.82 billion.

A possible indicator of goodwill impairment is the relationship of a company’s market capitalization to its book value. As of 
December 31, 2016, WESCO's market capitalization exceeded its book value and there were no impairment losses identified as 
a result of the annual test. Fair value determinations require considerable judgment and are sensitive to changes in underlying 
assumptions and factors. As a result, there can be no assurance that the estimates and assumptions made for purposes of the 
annual goodwill and indefinite-lived intangible impairment tests will prove to be an accurate prediction of future results. 

 Definite Lived Intangible Assets

Intangible assets are amortized over 2 to 20 years. A portion of intangible assets related to certain customer relationships are 
amortized using an accelerated method whereas all other intangible assets subject to amortization use a straight-line method that 
reflects the pattern in which the economic benefits of the respective assets are consumed or otherwise used. Intangible assets 
are tested for impairment if events or circumstances occur indicating that the respective asset might be impaired.

Insurance Programs

WESCO uses commercial insurance for auto, workers’ compensation, casualty and health claims as a risk-reduction strategy 

to minimize catastrophic losses. The Company’s strategy involves large deductible policies where WESCO must pay all costs 
up to the deductible amount. WESCO estimates the reserve for these programs based on historical incident rates and costs. The 
assumptions included in developing this accrual include the period of time between the incurrence and payment of a claim. The 
total liability related to the insurance programs was $9.5 million and $9.8 million at December 31, 2016 and 2015, respectively.

Income Taxes

WESCO accounts for income taxes under the asset and liability method, which requires the recognition of deferred income 

taxes for events that have future tax consequences. Under this method, deferred income taxes are recognized (using enacted 
tax laws and rates) based on the future income tax effects of differences in the carrying amounts of assets and liabilities for 
financial reporting and tax purposes. The effect of a tax rate change on deferred tax assets and liabilities is recognized in 
income in the period of change.

WESCO recognizes deferred tax assets at amounts that are expected to be realized. To make such determination, 
management evaluates all positive and negative evidence, including but not limited to, prior, current and future taxable 
income, tax planning strategies and future reversals of existing temporary differences. A valuation allowance is recognized if 
it is “more-likely-than-not” that some or all of a deferred tax asset will not be realized. WESCO regularly assesses the 
realizability of deferred tax assets.

No provision is made for undistributed earnings that are considered to be permanently reinvested to fund growth in foreign 

markets.

WESCO accounts for uncertainty in income taxes using a "more-likely-than-not" recognition threshold. Due to the 
subjectivity inherent in the evaluation of uncertain tax positions, the tax benefit ultimately recognized may materially differ 
from the estimate. WESCO recognizes interest and penalties related to uncertain tax benefits as part of interest expense and 
income tax expense, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

Debt Issuance Costs

WESCO capitalizes costs associated with the issuance of debt and such costs are amortized over the term of the respective 

debt instrument on a straight-line basis. Debt issuance costs are presented in the Consolidated Balance Sheets as a direct 
reduction from the carrying amount of the related debt liability. Upon prepayment of debt, the Company accelerates the 
recognition of an appropriate amount of the costs as refinancing or extinguishment of debt. During the year ending 
December 31, 2016, the Company capitalized debt issuance costs of $6.0 million. As of December 31, 2016 and 2015, 
unamortized debt issuance costs of $16.5 million and $17.7 million were recorded in the Consolidated Balance Sheets, 
respectively.

Convertible Debentures

WESCO separately accounted for the liability and equity components of the 6.0% Convertible Senior Debentures due 2029 

(the "2029 Debentures") in a manner that reflected its non-convertible debt borrowing rate. WESCO estimated its non-
convertible debt borrowing rate through a combination of discussions with its financial institutions and review of relevant 
market data. The discounts to the convertible debt balances were amortized to interest expense, using the effective interest 
method, over the implicit life of the debentures. 

Foreign Currency

The local currency is the functional currency for the majority 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 an exchange rate that approximates the average for the period. Translation adjustments 
arising from the use of differing exchange rates from period to period are included as a component of other comprehensive 
income (loss) within stockholders’ equity. Gains and losses from foreign currency transactions are included in net income for 
the period.

Defined Benefit Pension Plan

In connection with the December 14, 2012 acquisition of EECOL, the Company assumed a contributory defined benefit 
plan covering substantially all Canadian employees of EECOL. The plan provides retirement benefits based on earnings and 
credited service, and participants contribute 2% of their earnings to the plan. 

The Company also assumed EECOL's Supplemental Executive Retirement Plan (SERP), which provides additional pension 
benefits to certain executives based on earnings, credited service, and executive service. Participants in the SERP contribute 4% 
of their earnings to the SERP. 

Liabilities and expenses for pension benefits are determined using actuarial methodologies and incorporate significant 
assumptions, including the interest rate used to discount the future estimated cash flows, the expected long-term rate of return 
on plan assets, and several assumptions relating to the employee workforce (salary increases, retirement age, and mortality).

The interest rate used to discount future estimated cash flows is determined using the Canadian Institute of Actuaries 

("CIA") methodology, which references yield curve information provided by Fiera Capital. The discount rate used to determine 
benefit obligations for the Canadian pension was 3.9% in 2016. An increase in the discount rate of one quarter percent would 
decrease the projected benefit obligation by $4.7 million, and a decrease in the discount rate of one quarter percent would 
increase the projected benefit obligation by $5.1 million. The impact of a change in the discount rate of one quarter percent 
would be either a charge or credit of $0.3 million to earnings in the following year.

The expected long-term rate of return on plan assets is applied to the fair market-related value of plan assets. 

Stock-Based Compensation

WESCO's stock-based employee compensation plans are comprised of stock-settled stock appreciation rights, restricted 
stock units, and performance-based awards. Compensation cost for all stock-based awards is measured at fair value on the date 
of grant, and compensation cost is recognized, net of forfeitures, over the service period for awards expected to vest. The fair 
value of stock-settled appreciation rights and performance-based awards with market conditions is determined using the Black-
Scholes and Monte Carlo simulation models, respectively. The fair value of restricted stock units with service conditions and 
performance-based awards with performance conditions is determined by the grant-date closing price of WESCO's common 
stock. Expected volatilities are based on historical volatility of WESCO's common stock. WESCO estimates the expected life of 
stock-settled stock appreciation rights using historical data pertaining to option exercises and employee terminations. The risk-
free rate is based on the U.S. Treasury yields in effect at the time of grant. The forfeiture assumption is based on WESCO's 
historical employee behavior, which is reviewed on an annual basis. No dividends are assumed for stock-based awards.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

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, with cost determined on a weighted-average basis.

Fair Value of Financial Instruments

The Company measures the fair value of financial assets and liabilities in accordance with Financial Accounting Standards 
Board (FASB) Accounting Standards Codification (ASC) 820, "Fair Value Measurements and Disclosures," which defines fair 
value, establishes a framework for measuring fair value and expands disclosures about fair value measurements.

ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value and 
requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy gives 
the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and 
the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the 
fair value hierarchy are as follows:

• 

• 

• 

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that are accessible 
at the measurement date.

Level 2 inputs include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted 
prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in 
markets that are not active, or other inputs that are observable or can be corroborated by observable market data for 
substantially the full term of assets or liabilities.

Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to 
develop its own assumptions.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable and other 
accrued liabilities, and outstanding indebtedness. Except for the previously outstanding 2029 Debentures, the reported carrying 
amounts of WESCO’s debt instruments approximate their fair values. As described in Note 7, the 2029 Debentures were fully 
redeemed on September 15, 2016. At December 31, 2015, the carrying value of the 2029 Debentures was $177.8 million and 
the fair value was approximately $514.2 million. The Company uses a market approach to fair value all of its debt instruments, 
utilizing quoted prices in active markets, interest rates and other relevant information generated by market transactions 
involving similar instruments. Therefore, all of the Company's debt instruments are classified as Level 2 within the valuation 
hierarchy. For all of the Company's remaining financial instruments, carrying values are considered to approximate fair value.

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 that do not contribute to future revenue, are expensed. Liabilities are recorded when 
remedial efforts are probable and the costs can be reasonably estimated.  

Recently Adopted Accounting Pronouncements

In September 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity's Ability to Continue as a 
Going Concern. This ASU describes how an entity should assess its ability to meet obligations and sets disclosure requirements 
for how this information should be disclosed in the financial statements. The standard provides accounting guidance that will be 
used with existing auditing standards. The Company adopted this ASU in the first quarter of 2016. The adoption of this 
guidance did not have an impact on WESCO's consolidated financial statements and notes thereto.

In April 2015 and August 2015, the FASB issued Accounting Standards Update (ASU) 2015-03, Simplifying the 

Presentation of Debt Issuance Costs, and ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs 
Associated with Line-of-Credit Arrangements. These ASUs simplify the presentation of debt issuance costs by requiring that 
debt issuance costs related to a recognized liability be presented in the balance sheet as a direct deduction from the carrying 
amount of that debt liability, consistent with debt discounts. The Company adopted this new guidance on a retrospective basis 
effective January 1, 2016. Accordingly, the Company reclassified approximately $17.7 million of debt issuance costs from other 
noncurrent assets to long-term debt in the balance sheet as of December 31, 2015. See Note 7 of the Notes to Consolidated 
Financial Statements.

In May 2015, the FASB issued ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset 
Value per Share (or Its Equivalent). This updated guidance removes the requirement to categorize investments for which fair 

43

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

value is measured using the net asset value (NAV) per share practical expedient within the fair value hierarchy. The Company 
adopted this guidance on a retrospective basis effective January 1, 2016. The adoption of this ASU did not have an impact on 
WESCO's financial position, results of operations or cash flows; however, this guidance impacted the Company's defined 
benefit plan disclosure in Note 11 of the Notes to Consolidated Financial Statements as presented herein. Specifically, 
investments for which fair value is measured using the NAV per share practical expedient were removed from the tabular 
disclosure of the fair value hierarchy in all periods presented.

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes. This ASU simplifies the 

presentation of deferred income taxes by requiring that all deferred tax assets and liabilities, along with any related valuation 
allowance, be classified as noncurrent in the balance sheet. The Company elected to early adopt this ASU on a prospective basis 
during the first quarter of 2016. The adoption of this ASU did not have a material impact on WESCO's financial position and it 
had no impact on its results of operations or cash flows.

Recently Issued Accounting Pronouncements

In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of Effective Date. The 

Company previously reported that in May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, 
which provides a framework for addressing revenue recognition issues and replaces almost all existing revenue recognition 
guidance in current U.S. generally accepted accounting principles. The core principle of ASU 2014-09 is for companies to 
recognize revenue for the transfer of goods or services to customers in amounts that reflect the consideration to which the 
company expects to be entitled in exchange for those goods or services. ASU 2014-09 will also result in enhanced disclosures 
about revenue, provide guidance for transactions that were not previously addressed comprehensively, and improve guidance 
for multiple-element arrangements. The amendments in ASU 2015-14 defer the effective date of the new revenue recognition 
guidance to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. 
During 2016, the FASB issued four ASUs that address implementation issues and correct or improve certain aspects of the new 
revenue recognition guidance, including ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross 
versus Net), ASU 2016-10, Identifying Performance Obligations and Licensing, ASU 2016-12, Narrow-Scope Improvements 
and Practical Expedients and ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts 
with Customers. These ASUs do not change the core principles in the revenue recognition standard outlined above. The 
Company has developed a phased approach to implementing the new standard. We are currently in the assessment phase and 
cannot reasonably estimate the financial statement impact of the future adoption.

In February 2016, the FASB issued ASU 2016-02, Leases, a comprehensive new standard that amends various aspects of
existing accounting guidance for leases, including the recognition of a right-of-use asset and a lease liability on the balance
sheet and disclosing key information about leasing arrangements. This guidance is effective for fiscal years beginning after
December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The new leasing standard
requires modified retrospective transition, which requires application of the new guidance at the beginning of the earliest
comparative period presented in the year of adoption. Management is currently evaluating the impact of this new standard on
WESCO's consolidated financial statements and notes thereto.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to 

Employee Share-Based Payment Accounting, which simplifies several aspects of accounting for share-based payment 
transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on 
the statement of cash flows. The amendments in this ASU affect all entities that issue share-based payment awards to their 
employees. This ASU will be effective in the first quarter of 2017. The impact of this new guidance is dependent upon future 
equity award exercises and stock prices, which cannot be predicted. Therefore, the Company is unable to determine the 
significance of the impact on its reported income taxes or cash flows from operating activities. 

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit 

Losses on Financial Instruments, which introduces new guidance for the accounting for credit losses on certain financial 
instruments. The amendments in ASU 2016-13 are effective for fiscal years beginning after December 15, 2019, including 
interim periods within those fiscal years and early adoption is permitted. Management is currently evaluating the impact of this 
accounting standard on WESCO's consolidated financial statements and notes thereto. 

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash 
Receipts and Cash Payments (a consensus of the Emerging Issues Task Force). This ASU provides guidance on eight specific 
cash flow issues where there is diversity in practice. The amendments in this ASU are effective for fiscal years beginning after 
December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim 
period. Management is currently evaluating the impact of this accounting standard on WESCO's consolidated financial 
statements and notes thereto.

44

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than 
Inventory. The purpose of ASU 2016-16 is to simplify the income tax accounting of an intra-entity transfer of an asset other 
than inventory and to record its effect when the transfer occurs. The guidance is effective for annual reporting periods 
beginning after December 15, 2017, including interim reporting periods within those annual reporting periods and early 
adoption is permitted. The Company will early adopt this ASU on a modified retrospective basis in the first quarter of 2017. 
The adoption of this ASU is not expected to have a material impact on WESCO's financial position and it will have no impact 
on its results of operations or cash flows.

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for 
Goodwill Impairment, which eliminates Step 2 from the goodwill impairment test. Under the amendments in this update, an 
entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its 
carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the 
reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that 
reporting unit. An entity should apply the amendments in this ASU on a prospective basis. This guidance is effective for fiscal 
years beginning after December 15, 2019, including interim periods within those fiscal years. Management has not yet 
evaluated the impact of this accounting standard on WESCO's consolidated financial statements and notes thereto.   

Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are 

either not applicable or are not expected to be significant to WESCO’s financial position, results of operations or cash flows.

4. 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 commercial, institutional and government markets. Based upon WESCO’s broad customer base, the 
Company has concluded that it has no material credit risk as a result of customer concentration. Our largest supplier is Eaton 
Corporation, accounting for approximately 11% of our purchases in 2016 and 2015, respectively, and 12% in 2014. Therefore, 
WESCO could potentially incur risk due to supplier concentration.

The fair values of assets acquired and liabilities assumed during the year ended December 31, 2016, which are primarily for 

the acquisition of Atlanta Electrical Distributors, LLC, are based upon preliminary calculations and valuations. WESCO's 
estimates and assumptions for its preliminary purchase price allocations are subject to change as it obtains additional 
information for its estimates during the respective measurement periods (up to one year from the respective acquisition date). 

Acquisition of Atlanta Electrical Distributors, LLC

On March 14, 2016, WESCO Distribution, Inc. ("WESCO Distribution") completed the acquisition of Atlanta Electrical 
Distributors, LLC, an Atlanta-based electrical distributor focused on the construction and MRO markets from five locations in 
Georgia with approximately $85 million in annual sales. WESCO Distribution funded the purchase price paid at closing with 
borrowings under its revolving credit facility. The purchase price was allocated to the respective assets and liabilities based 
upon their estimated fair values as of the acquisition date. In addition to the cash paid at closing, the purchase price includes a 
contingent payment that may be earned upon the achievement of certain financial performance targets over three consecutive 
one year periods. The fair value of the contingent consideration was determined using a probability-weighted outcome analysis 
and Level 3 inputs such as internal forecasts. This amount has been accrued at the maximum potential payout under the terms of 
the purchase agreement and it is included in the fair value of liabilities assumed as presented above. The preliminary fair value 
of intangibles was estimated by management and the allocation resulted in intangible assets of $21.8 million and goodwill of 
$30.0 million. The intangible assets include customer relationships of $15.8 million amortized over 13 and 14 years, a 

46

 
 
 
WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

trademark of $6.0 million amortized over 13 years, and non-compete agreements of less than $0.1 million amortized over 5 
years. No residual value is estimated for the intangible assets being amortized. Management believes that the majority of 
goodwill is deductible for tax purposes.

2015 Acquisitions of Hill Country Electric Supply, LP and Needham Electric Supply Corporation

On May 1, 2015, WESCO Distribution completed the acquisition of Hill Country Electric Supply, LP ("Hill Country"), an 

electrical distributor focused on the commercial construction market from nine locations in Central and South Texas with 
approximately $140 million in annual sales. WESCO Distribution funded the purchase price paid at closing with borrowings 
under its prior revolving credit facility. The purchase price was allocated to the respective assets and liabilities based upon their 
estimated fair values as of the acquisition date. The fair value of intangibles was estimated by management and the allocation 
resulted in intangible assets of $21.1 million and goodwill of $16.2 million. The majority of goodwill is deductible for tax 
purposes.

On October 30, 2015, WESCO Distribution completed the acquisition of Needham Electric Supply Corporation 

("Needham"), an electrical distributor focused on the commercial construction and lighting national account markets from 24 
locations in Massachusetts, New Hampshire and Vermont with approximately $115 million in annual sales. WESCO 
Distribution funded the purchase price paid at closing with cash and borrowings under its revolving credit facility. The purchase 
price was allocated to the respective assets and liabilities based upon their estimated fair values as of the acquisition date. The 
fair value of intangibles was estimated by management and the allocation resulted in intangible assets of $31.0 million and 
goodwill of $35.7 million. The majority of goodwill is deductible for tax purposes.

For the acquisitions of Hill Country and Needham that were made in 2015, the intangible assets include customer 

relationships of $37.6 million amortized over 11 to 14 years, trademarks of $14.3 million amortized over 12 and 13 years, and 
other intangibles of $0.2 million. No residual value is estimated for the intangible assets being amortized.

2014 Acquisitions of LaPrairie, Inc., Hazmasters, Inc. and Hi-Line Utility Supply

On February 1, 2014, WESCO Distribution, through its wholly-owned Canadian subsidiary, completed the acquisition of 

LaPrairie, Inc. ("LaPrairie"), a wholesale distributor of electrical products with approximately $30 million in annual sales 
servicing the transmission, distribution, and substation needs of utilities and utility contractors from a single location in 
Newmarket, Ontario. WESCO funded the purchase price paid at closing with cash. The purchase price was allocated to the 
respective assets and liabilities based upon their estimated fair values as of the acquisition date. The fair value of intangibles 
was determined by management and the allocation resulted in intangible assets of $11.0 million and goodwill of $8.9 million. 
The majority of goodwill is deductible for tax purposes.

On March 17, 2014, WESCO Distribution, through its wholly-owned Canadian subsidiary, completed the acquisition of 
Hazmasters, Inc. ("Hazmasters"), a leading independent Canadian distributor of safety products with approximately $80 million 
in annual sales servicing customers in the industrial, construction, and commercial, institutional and government markets from 
14 branches across Canada. WESCO funded the purchase price paid at closing with cash and borrowings under its prior 
revolving credit facility. The purchase price was allocated to the respective assets and liabilities based upon their estimated fair 
values as of the acquisition date. The fair value of intangibles was estimated by management and the allocation resulted in 
intangible assets of $28.1 million and goodwill of $29.5 million, which is not deductible for tax purposes.   

On June 11, 2014, WESCO Distribution, completed the acquisition of Hi-Line Utility Supply ("Hi-Line"), a provider of 
utility MRO and safety products, as well as rubber goods testing and certification services, with approximately $30 million in 
annual sales from locations in Chicago, Illinois and Millbury, Massachusetts. WESCO Distribution funded the purchase price 
paid at closing with cash. The purchase price was allocated to the respective assets and liabilities based upon their estimated fair 
values as of the acquisition date. The fair value of intangibles was estimated by management and the allocation resulted in 
intangible assets of $14.2 million and goodwill of $24.0 million. The majority of goodwill is deductible for tax purposes.

For the acquisitions of LaPrairie, Hazmasters, and Hi-Line that were made in 2014, the intangible assets include customer 

relationships of $38.9 million amortized over 2 to 12 years, supplier relationships of $3.2 million amortized over 10 years, 
trademarks of $10.9 million, and other intangibles of $0.3 million. Certain trademarks have been assigned an indefinite life 
while others are amortized over 5 years and 10 years. No residual value is estimated for the intangible assets being amortized.

On September 24, 2015, WESCO Distribution amended and restated its accounts receivable securitization facility (the 

"Receivables Facility") pursuant to the terms and conditions of a Fourth Amended and Restated Receivables Purchase 
Agreement (the “Receivables Purchase Agreement”), by and among WESCO Receivables Corp. (“WESCO Receivables”), 
WESCO Distribution, the various purchaser groups from time to time party thereto and PNC Bank, National Association, as 

48

 
 
 
 
 
 
 
 
 
WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

Administrator. The Receivables Purchase Agreement amended and restated the receivables purchase agreement entered into on 
April 13, 2009.  

The Receivables Purchase Agreement increased the purchase limit from $500 million to $550 million, with the opportunity 

to exercise an accordion feature which permits increases in the purchase limit of up to $100 million, extended the term of the 
Receivables Facility to September 24, 2018 and added and amended certain defined terms. The interest rate spread and 
commitment fee of the Receivables Facility remained at 0.95% and 0.45%, respectively. 

Under the Receivables Facility, WESCO sells, on a continuous basis, an undivided interest in all domestic accounts 
receivable to WESCO Receivables, a wholly owned special purpose entity (the “SPE”). The SPE sells, without recourse, a 
senior undivided interest in the receivables to financial institutions for cash while maintaining a subordinated undivided interest 
in the receivables, in the form of overcollateralization. WESCO has agreed to continue servicing the sold receivables for the 
third-party conduits and financial institutions at market rates; accordingly, no servicing asset or liability has been recorded.

As of December 31, 2016 and 2015, accounts receivable eligible for securitization totaled approximately $657.5 million and 

$684.7 million, respectively. The Consolidated Balance Sheets as of December 31, 2016 and 2015 include $380.0 million and 
$525.0 million, respectively, of account receivable balances legally sold to third parties, as well as borrowings for equal 
amounts. At December 31, 2016, the interest rate on borrowings under this facility was approximately 1.4%.

Revolving Credit Facility

On September 24, 2015, WESCO International, WESCO Distribution and certain other subsidiaries of the Company entered 
into a $600 million revolving credit facility (the “Revolving Credit Facility”), which contains a letter of credit sub-facility of up 
to $125 million, pursuant to the terms and conditions of a Second Amended and Restated Credit Agreement (the "Credit 
Agreement"). The Revolving Credit Facility contains an accordion feature allowing WESCO Distribution to request increases 
to the borrowing commitments, subject to customary conditions. This accordion feature increased from $100 million to $200 
million in the aggregate. The Revolving Credit Facility replaced WESCO Distribution’s prior revolving credit facility entered 
into on December 12, 2012.  

The Revolving Credit Facility matures in September 2020 and consists of two separate sub-facilities: (i) a Canadian sub-
facility with a borrowing limit of up to $400 million, which is collateralized by substantially all assets of WESCO Canada and 
the other Canadian Borrowers, other than, among other things, real property, in each case, subject to customary exceptions and 
limitations, and (ii) a U.S sub-facility with a borrowing limit of up to $600 million less the amount of outstanding borrowings 
under the Canadian sub-facility. The U.S. sub-facility is collateralized by substantially all assets of WESCO Distribution and its 
domestic subsidiaries which are party to the Credit Agreement, other than, among other things, real property and accounts 
receivable sold or intended to be sold pursuant to the Receivables Purchase Agreement. The applicable interest rate for 
borrowings under the Revolving Credit Facility includes interest rate spreads based on available borrowing capacity that range 
between 1.25% and 1.75% for LIBOR-based borrowings and 0.25% and 0.75% for prime rate-based borrowings. At 
December 31, 2016, the interest rate on borrowings under this facility was approximately 2.0%. 

The Credit Agreement requires ongoing compliance with certain customary affirmative and negative covenants. The Credit 

Agreement also contains customary events of default. 

During 2016, WESCO borrowed $1,025.8 million under the Revolving Credit Facility and made repayments in the 

aggregate amount of $1,096.8 million. During 2015, aggregate borrowings and repayments were $1,276.0 million and $1,209.0 
million, respectively. WESCO had $509.7 million available under the Revolving Credit facility at December 31, 2016, after 
giving effect to $26.5 million of outstanding letters and international lines of credit, as compared to approximately $438.7 
million available under the Revolving Credit facility at December 31, 2015, after giving effect to $40.3 million of outstanding 
letters and international lines of credit.

International Lines of Credit

Certain foreign subsidiaries of WESCO have entered into uncommitted lines of credit, which serve as overdraft facilities, to 

support local operations. The maximum borrowing limit varies by facility and ranges between $0.3 million and $21.0 million. 
The applicable interest rate for borrowings under these lines of credit varies by country and is governed by the applicable loan 
agreement. The international lines of credit are renewable on an annual basis and certain facilities are fully and unconditionally 
guaranteed by WESCO Distribution. Accordingly, borrowings under these lines directly reduce availability under the Revolving 
Credit Facility.

Term Loan Facility 

On December 12, 2012, WESCO Distribution, as U.S. borrower, WDCC Enterprises Inc. ("WDCC" and together with 

WESCO Distribution, the “Borrowers”), as Canadian borrower, and WESCO International entered into a Term Loan Agreement 

49

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

(the “Term Loan Agreement”) among WESCO Distribution, WDCC, the Company, the lenders party thereto and Credit Suisse 
AG Cayman Islands Branch, as administrative agent and as collateral agent. 

The Term Loan Agreement provided a seven-year term loan facility (the “Term Loan Facility”), which consisted of two 

separate sub-facilities: (i) a Canadian sub-facility in an aggregate principal amount of CAD150 million, issued at a 2.0% 
discount, and (ii) a U.S. sub-facility in an aggregate principal amount of $700 million, issued at a 1.0% discount. The proceeds 
of the Term Loan Facility were used to finance the acquisition of EECOL, and to pay fees and expenses incurred in connection 
with the acquisition and certain other transactions. Subject to the terms of the Term Loan Agreement, the Borrowers may 
request incremental term loans from time to time in an aggregate principal amount not to exceed at any time $300 million, with 
an equivalent principal amount in U.S. dollars being calculated for any incremental term loan denominated in Canadian dollars.  

On November 19, 2013, the Borrowers and WESCO International entered into an amendment (the “Term Loan 

Amendment”) to the Term Loan Agreement. The Term Loan Amendment, among other things, reduced the applicable margin 
on U.S. term loans by 0.50% and the LIBOR floor applicable to the U.S. sub-facility from 1.00% to 0.75%. The modified 
pricing terms were effective December 13, 2013.

On November 26, 2013, WESCO Distribution sold $500 million aggregate principal amount of 5.375% Senior Notes due 

2021 (the “2021 Notes”), and used the net proceeds plus excess cash to prepay $500 million under the Company's U.S. sub-
facility of the Term Loan Facility (see discussion below under “5.375% Senior Notes due 2021” for additional information). 
The prepayment satisfied all remaining quarterly repayment obligations under the U.S. sub-facility. As of December 31, 2016, 
the amount outstanding under the U.S. sub-facility was $144.8 million. The Canadian sub-facility was fully repaid in 2015 
using cash provided by Canadian operations.

Borrowings under the Term Loan Facility bear interest at base rates plus applicable margins. At December 31, 2016, the 
interest rate on borrowings under the U.S. sub-facility was 4.0%. To the extent not previously paid, the outstanding U.S. sub-
facility will become due and payable on December 12, 2019, with any unpaid incremental term loans becoming due and 
payable on the respective maturity dates applicable to those incremental term loans. At any time or from time to time, the 
Borrowers may prepay borrowings under the Term Loan Facility in whole or in part without premium or penalty. The 
Borrowers' obligations under the Term Loan Facility are secured by substantially all of the assets of the Borrowers, the 
Company and certain of the Company's other subsidiaries; provided that, with respect to borrowings under the U.S. sub-facility, 
the collateral does not include assets of certain foreign subsidiaries or more than 65% of the issued and outstanding equity 
interests in certain foreign subsidiaries. 

The Term Loan Facility contains customary affirmative and negative covenants for credit facilities of this type. The Term 

Loan Facility also provides for customary events of default.

5.375% Senior Notes due 2021

In November 2013, WESCO Distribution issued $500 million aggregate principal amount of  2021 Notes through a private 
offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The 2021 
Notes were issued at 100% of par and are governed by an indenture (the “2021 Indenture”) entered into on November 26, 2013 
with WESCO International and U.S. Bank National Association, as trustee. The 2021 Notes are unsecured senior obligations of 
WESCO Distribution and are guaranteed on a senior unsecured basis by WESCO International. The 2021 Notes bear interest at 
a stated rate of 5.375%, payable semi-annually in arrears on June 15 and December 15 of each year. In addition, WESCO 
incurred costs related to the issuance of the 2021 Notes totaling $8.4 million, which are recorded as a reduction to the carrying 
value of the debt and are being amortized over the life of the notes. The 2021 Notes mature on December 15, 2021. The net 
proceeds of the 2021 Notes were used to prepay a portion of the U.S. sub-facility of the term loans due 2019. 

Under the terms of a registration rights agreement dated as of November 26, 2013 among WESCO Distribution, WESCO 
International and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as the representative of the initial purchasers of the 2021 
Notes, WESCO Distribution and WESCO International agreed to register under the Securities Act notes having terms identical 
in all material respects to the 2021 Notes (the “2021 Exchange Notes”) and to make an offer to exchange the 2021 Exchange 
Notes for the 2021 Notes. WESCO Distribution launched the exchange offer on June 12, 2014 and the exchange offer expired 
on July 17, 2014.   

At any time on or after December 15, 2016, WESCO Distribution may redeem all or a part of the 2021 Notes. Between 
December 15, 2016 and December 14, 2017, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption 
price equal to 104.031% of the principal amount. Between December 15, 2017 and December 14, 2018, WESCO Distribution 
may redeem all or a part of the 2021 Notes at a redemption price equal to 102.688% of the principal amount. Between 
December 15, 2018 and December 14, 2019, WESCO Distribution may redeem all or a part of the 2021 Notes at a redemption 
price equal to 101.344% of the principal amount. On and after December 15, 2019, WESCO Distribution may redeem all or a 
part of the 2021 Notes at a redemption price equal to 100% of the principal amount.

The 2021 Indenture contains customary covenants and customary events of default. In addition, upon a change of control, 

the holders of 2021 Notes have the right to require WESCO Distribution to repurchase all or any part of the 2021 Notes at a 
redemption price equal to 101% of the principal amount, plus accrued and unpaid interest.  

5.375% Senior Notes due 2024 

In June 2016, WESCO Distribution issued $350 million aggregate principal amount of 5.375% Senior Notes due 2024 (the 
"2024 Notes") through a private offering exempt from the registration requirements of the Securities Act. The 2024 Notes were 
issued at 100% of par and are governed by an indenture (the “2024 Indenture”) entered into on June 15, 2016 among WESCO 
Distribution, as issuer, WESCO International, as parent guarantor, and U.S. Bank National Association, as trustee. The 2024 
Notes are unsecured senior obligations of WESCO Distribution and are guaranteed on a senior unsecured basis by WESCO 
International. The 2024 Notes bear interest at a rate of 5.375% per annum, payable semi-annually in arrears on June 15 and 
December 15 of each year, commencing on December 15, 2016. WESCO incurred costs totaling $6.0 million to issue the 2024 
Notes, which are recorded as a reduction to the carrying value of the debt and are being amortized over the life of the note. The 
notes mature on June 15, 2024. The Company used the net proceeds to redeem its 2029 Debentures on September 15, 2016.

Under the terms of a registration rights agreement dated as of June 15, 2016 among WESCO Distribution, as the issuer, 
WESCO International, as parent guarantor, and Goldman, Sachs & Co., as representative of the initial purchasers of the 2024 
Notes, WESCO Distribution and WESCO International agreed to register under the Securities Act notes having terms identical 
in all material respects to the 2024 Notes (the “2024 Exchange Notes”) and to make an offer to exchange the 2024 Exchange 
Notes for the 2024 Notes. WESCO Distribution launched the exchange offer on December 28, 2016 and the exchange offer 
expired on January 31, 2017. 

At any time on or after June 15, 2019, WESCO Distribution may redeem all or a part of the 2024 Notes. Between June 15, 

2019 and June 14, 2020, WESCO Distribution may redeem all or a part of the 2024 Notes at a redemption price equal to 
104.031% of the principal amount. Between June 15, 2020 and June 14, 2021, WESCO Distribution may redeem all or a part of 
the 2024 Notes at a redemption price equal to 102.688% of the principal amount. Between June 15, 2021 and June 14, 2022, 
WESCO Distribution may redeem all or a part of the 2024 Notes at a redemption price equal to 101.344% of the principal 
amount. On and after June 15, 2022, WESCO Distribution may redeem all or a part of the 2024 Notes at a redemption price 
equal to 100% of the principal amount.    

The 2024 Indenture contains customary covenants and events of default. Upon a change of control, the holders of the 2024 
Notes have the right to require WESCO Distribution to repurchase all or any part of the 2024 Notes at a redemption price equal 
to 101% of the principal amount thereof, plus accrued and unpaid interest. 

6.0% Convertible Senior Debentures due 2029

On August 27, 2009, WESCO International completed an exchange offer pursuant to which it issued $345 million in 
aggregate principal amount of the 2029 Debentures. The 2029 Debentures were issued pursuant to an Indenture dated August 
27, 2009, with The Bank of New York Mellon, as trustee, and were unconditionally guaranteed on an unsecured senior 
subordinate basis by WESCO Distribution. 

WESCO separately accounted for the liability and equity components of its 2029 Debentures in a manner that reflected its 
non-convertible debt borrowing rate. WESCO utilized an interest rate of 13.875% to reflect the non-convertible debt borrowing 
rate of its offering upon issuance, which was determined based on discussions with its financial institutions and a review of 
relevant market data, and resulted in a $181.2 million discount to the 2029 Debenture balance and a net increase in additional 
capital of $106.5 million. As of December 31, 2015, the net equity included in additional capital related to the 2029 Debentures 
totaled $106.3 million. In addition, the financing costs incurred to issue the 2029 Debentures were allocated between the 
instrument's debt and equity components. WESCO amortized the debt discount and financing costs over the life of the 
instrument. For the years ended December 31, 2016, 2015 and 2014, non-cash interest expense for the amortization of the debt 
discount and debt issuance costs was $3.1 million, $4.2 million and $3.8 million, respectively.

On September 15, 2016, the Company redeemed the 2029 Debentures. Holders of the 2029 Debentures received cash 

totaling $344.8 million, which was equal to the principal amount of the then-outstanding debentures, in addition to accrued and 
unpaid interest. Holders who surrendered the 2029 Debentures for conversion received 18 shares of WESCO stock for each 
$1,000 principal amount of 2029 Debentures converted. In total, 6,267,688 shares were issued on the redemption date. The 
redemption resulted in a non-cash loss of $123.9 million, which included the write off of unamortized debt issuance costs.

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; (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 Facility and the Receivables Facility require WESCO to meet certain fixed charge coverage tests depending 
on availability or liquidity, respectively.

8. CAPITAL STOCK

Preferred Stock

There are 20 million shares of preferred stock authorized at a par value of $.01 per share; there are no shares issued or 

outstanding. 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 million shares of common stock and 20 million 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.

The terms of the Revolving Credit Facility and the Term Loan Facility provide certain limits on declaring or paying 
dividends. In addition, the indentures governing the 2021 Notes and 2024 Notes place limits on the Company's ability to pay 
dividends and repurchase common stock. At December 31, 2016 and 2015, no dividends had been declared and, therefore, no 
retained earnings were reserved for dividend payments.

As of December 31, 2016, WESCO’s foreign subsidiaries had unremitted earnings of approximately $759.9 million, of 

which $668.0 million was attributable to the Company's Canadian operations. WESCO asserts that these earnings are 
permanently reinvested to fund growth in the foreign markets and, therefore, has not provided a deferred tax liability on these 
earnings. Additionally, WESCO’s current plans do not require that these earnings be repatriated to fund liquidity needs in the 
U.S. It is not practicable for WESCO to determine the deferred tax liability associated with repatriation of these earnings as 
such determination involves material uncertainties, however, if these earnings were repatriated and taxed at the U.S. statutory 
rate of 35%, the unrecognized deferred tax liability would be approximately $266.0 million.

As of December 31, 2016 and 2015, WESCO had deferred tax assets of $10.0 million and $12.6 million, respectively, 
related to Canadian net operating loss carryforwards. The Canadian net operating loss carryforwards expire beginning in 2029 
through 2036. Additionally, WESCO had deferred tax assets of $6.2 million and $5.3 million as of December 31, 2016 and 
2015, respectively, related to non-Canadian foreign net operating loss carryforwards. These net operating loss carryforwards 
expire beginning in 2019, while some may be carried forward indefinitely. As of December 31, 2016 and 2015, WESCO had 
deferred tax assets of $3.2 million related to state net operating loss carryforwards. These carryforwards expire beginning in 
2022 through 2035. The Company has determined, based upon an evaluation of all available positive and negative evidence, 
that it "more-likely-than-not" will utilize all of its net operating loss carryforwards before expiration other than those recently 
incurred in a non-Canadian foreign location. Accordingly, the Company recorded a partial valuation allowance of $1.4 million 
against the total deferred tax asset related to the non-Canadian foreign net operating loss carryforwards of $2.2 million at 
December 31, 2016.

As of December 31, 2016 and 2015, WESCO had deferred tax assets of $15.7 million and $11.5 million, respectively, 

related to U.S. foreign tax credit (“FTC”) carryforwards. These FTC carryforwards expire beginning in 2019 through 2025. The 
Company has determined that prudent and feasible tax planning strategies exist and it intends to implement these tax planning 
strategies to prevent these FTC carryforwards from expiring unused. Accordingly, a valuation allowance has not been recorded.

only in connection with the Mutual Agreement Procedure (“MAP”) concluded in the fourth quarter of 2015 between the 
Competent Authorities of the Internal Revenue Service (“IRS”) and Canada Revenue Agency (“CRA”) with respect to transfer 
pricing matters and matters pending before the Appeals Division of Canada Revenue Agency. The statutes of limitation with 
respect to the Company’s 2008 to 2011 U.S. federal income tax returns are open by waiver only in connection with the Advance 
Pricing Agreement (“APA”) concluded in the fourth quarter of 2015 between the IRS and CRA. The APA resolves certain 
transfer pricing matters for the 2008 to 2018 tax years. The statute of limitation with respect to the Company’s 2012 U.S. 
federal income tax return is open by waiver only in connection with the IRS examination of the 2012 and 2013 years and the 
APA.

The total amount of unrecognized tax benefits were $6.2 million, $5.4 million, and $20.0 million as of December 31, 2016, 

2015 and 2014, respectively. The amount of unrecognized tax benefits that would affect the effective tax rate if recognized in 
the consolidated financial statements was $7.5 million, $6.2 million, and $20.4 million, respectively. The amount for 2014 
primarily related to transfer pricing adjustments made by Canada Revenue Agency, which were subject to MAP and APA 
proceedings under the U.S./Canada income tax treaty. These proceedings concluded in the fourth quarter of 2015.

It is reasonably possible that the amount of unrecognized tax benefits will decrease by approximately $0.9 million within the 

next twelve months due to the settlement of uncertain tax positions related to Internal Revenue Service audits or the expiration 
of statutes of limitation. Of this amount, approximately $0.3 million could impact the effective tax rate. 

The Company classifies interest related to unrecognized tax benefits as interest income or expense. Interest expense on 
unrecognized tax benefits was $1.2 million and $1.0 million for 2016 and 2014, respectively. In 2015, interest income of $8.7 
million was recognized as a result of the conclusion of the MAP and APA proceedings for the 2004 to 2015 tax years. As of 
December 31, 2016 and 2015, WESCO had an accrued liability of $2.2 million and $2.1 million, respectively, for interest 
expense related to unrecognized tax benefits. The Company classifies penalties related to unrecognized tax benefits as part of 
income tax expense. Penalties recorded in income tax expense were immaterial in 2016, 2015, and 2014.

10. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income attributable to WESCO International by the weighted-average 

number of common shares outstanding during the periods. Diluted earnings per share is computed by dividing net income 
attributable to WESCO International 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, which includes consideration of equity awards and contingently convertible debt.

The following tables set forth the details of basic and diluted earnings per share:

The computation of diluted earnings per share attributable to WESCO International excluded equity awards of 

approximately 1.2 million for the years ended December 31, 2016 and 2015, and 0.3 million for the year ended December 31, 
2014. These shares were excluded because their effect would have been antidilutive.

Because of WESCO’s previous obligation to settle the par value of the 2029 Debentures in cash upon conversion, WESCO 

was required to include shares underlying the 2029 Debentures in its diluted weighted-average shares outstanding when the 
average stock price per share for the period exceeded the conversion price of the debentures. Only the number of shares that 
would have been issuable under the treasury stock method of accounting for share dilution were included, which was based 
upon the amount by which the average stock price exceeded the conversion price. The conversion price of the 2029 Debentures 
was $28.87 and the maximum amount of share dilution was limited to 11,951,932 shares. For the years ended December 31, 
2016, 2015, and 2014, the effect of the 2029 Debentures on diluted earnings per share attributable to WESCO International was 
a decrease of $0.17, $0.60, and $0.89, respectively.

In December 2014, the Company's Board of Directors authorized the repurchase of up to $300 million of the Company's 
common stock through December 31, 2017. During the year ended December 31, 2015, the Company entered into accelerated 
stock repurchase agreements (the "ASR Transactions") with certain financial institutions to purchase shares of its common 
stock. In exchange for up-front cash payments totaling $150.0 million, the Company received 2,468,576 shares. The total 
number of shares ultimately delivered under the ASR Transactions was determined by the average of the volume-weighted-
average prices of the Company's common stock for each exchange business day during the respective settlement valuation 
periods. WESCO funded the repurchases with borrowings under its prior revolving credit facility. For purposes of computing 
earnings per share in 2015, share repurchases have been reflected as a reduction to common shares outstanding on the 
respective share delivery dates.

11. EMPLOYEE BENEFIT PLANS  

Defined Contribution Plans

A majority of WESCO’s employees are covered by defined contribution retirement savings plans for their service rendered 

subsequent to WESCO’s formation. WESCO also offers a deferred compensation plan for select individuals. For U.S. 
participants, WESCO matches contributions made by employees at an amount equal to 50% of the participants' total monthly 
contributions up to a maximum of 6% of eligible compensation. For Canadian participants, WESCO will make contributions in 
an amount ranging from 3% to 5% of participants' eligible compensation based on years of continuous service. In addition, for 
U.S. participants, employer contributions may be made at the discretion of the Board of Directors. A discretionary employer 
contribution charge of $9.7 million was incurred in 2014. For the years ended December 31, 2016, 2015 and 2014, WESCO 
incurred charges of $18.5 million, $18.1 million, and $28.3 million, respectively, for all such plans. Contributions are made in 
cash to employee retirement savings plan accounts. The deferred compensation plan is an unfunded plan. As of  December 31, 
2016 and 2015, the Company's obligation under the deferred compensation plan was $21.7 million and $23.5 million, 
respectively. Employees have the option to transfer balances allocated to their accounts in the defined contribution retirement 
savings plan and the deferred compensation plan into any of the available investment options.

Defined Benefit Plans

In connection with the December 14, 2012 acquisition of EECOL, the Company assumed a contributory defined benefit 
plan (the "Plan") covering substantially all Canadian employees of EECOL. The Plan provides retirement benefits based on 
earnings and credited service, and participants contribute 2% of their earnings to the Plan. Participants become 100% vested 
after two years of continuous service.  

The Company also assumed EECOL's Supplemental Executive Retirement Plan (the "SERP"), which provides additional 

pension benefits to certain executives based on earnings, credited service and executive service. Participants in the SERP 
become 100% vested after two years of continuous service and contribute 4% of their earnings to the SERP.

The Plan's long-term overall objective is to maintain benefits at their current level without affecting the cost of maintaining 

the Plan, assuming that the demographic make-up of the group of members remains the same.  

The primary investment objective, in support of the overall objective, is to earn the highest rate of return possible for the 
Plan, while keeping risk at acceptable levels. The long-term return objective of the Plan is to achieve a minimum annualized 
rate of return in excess of the actuarial requirements. This translates into a required return of 3.0% above inflation, net of 
investment management fees. The return objective is consistent with the overall investment risk level that the Plan assumes in 
order to meet the pension obligations of the Plan. To achieve this long term investment objective, the Plan has adopted an asset 
mix that has a combination of equity and fixed income investments. Risk is controlled by investing in a well-diversified 
portfolio of asset classes. A benchmark portfolio is established based on the expected returns for each asset class available. The 
investment of the Plan's assets in accordance with the benchmark portfolio should enable the Plan to not only attain, but also 
exceed the minimum overall objective. 

The following table presents the target asset mix based on market value for each investment category within which the 

investment managers must invest the Plan's assets. The asset mix is reviewed and rebalanced to target on an annual basis.

The Plan's assets are measured at fair value, which is defined as the price that would be received to sell an asset or paid to 

transfer a liability in an orderly transaction between market participants at the measurement date. As described in Note 2, 
"Accounting Policies," financial assets and liabilities are classified in the fair value hierarchy based on the lowest level of any 
input that is significant to the measurement of fair value. Investments for which fair value is measured using the NAV per share 
practical expedient are not classified in the fair value hierarchy. The following describes the valuation methodologies used to 
measure the fair value of the Plan's assets.

Pooled Equity Investments. These investments consist of the Plan's share of segregated funds that invest primarily in 

equity securities. The funds are valued at the net asset value of shares held at December 31.

Pooled Fixed Income Investments. These investments consist of a segregated fund that primarily invests in Canadian 

issued bonds and debentures and is valued at the net asset value of shares held in the underlying funds.

Other Investments. These investments consist of money market and diversified growth funds. The diversified growth fund 

invests in a broad range of asset classes, including equities, bonds, infrastructure, property, commodities and absolute return 
strategies. These investments are valued at the net asset value of shares held in the underlying funds.

The fair value methods described above may not be indicative of net realizable value or reflective of future fair values. 
Additionally, while the Company believes the valuation methods are appropriate and consistent with other market participants, 
the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a 
different fair value measurement at the reporting date.

12. STOCK-BASED COMPENSATION

WESCO sponsors four stock-based compensation plans. The 1999 Long-Term Incentive Plan, as amended and restated 
(“LTIP”), was designed to be the successor plan to all prior plans. Any shares remaining reserved for future issuance under the 
prior plans are available for issuance under the LTIP. The LTIP and predecessor plans are administered by the Compensation 
Committee of the Board of Directors.

On May 30, 2013, the Company renewed and restated the LTIP, increasing the maximum number of shares of common 
stock that may be issued under the plan by 1.6 million shares to 4.0 million. Under the LTIP, the total number of shares of 
common stock authorized to be issued under the LTIP will be reduced by 1 share of common stock for every 1 share that is 
subject to an option or stock appreciation right granted, and 1.83 shares of common stock for every 1 share that is subject to an 
award other than an option or stock appreciation right granted on or after May 30, 2013. As of December 31, 2016, 2.4 million 
shares of common stock were reserved under the LTIP for future equity award grants. 

Except for the performance-based award, awards granted vest and become exercisable once criteria based on time is 

achieved. Performance-based awards vest based on market or performance conditions. All awards vest immediately in the event 
of a change in control. Each award terminates on the tenth anniversary of its grant date unless terminated sooner under certain 
conditions.

WESCO recognized $12.5 million, $12.9 million and $14.8 million of non-cash stock-based compensation expense, which 

is included in selling, general and administrative expenses, for the years ended December 31, 2016, 2015 and 2014, 
respectively. As of December 31, 2016, there was $16.8 million of total unrecognized compensation expense related to non-
vested stock-based compensation arrangements for all awards previously made of which approximately $9.9 million is expected 
to be recognized in 2017, $5.9 million in 2018 and $1.0 million in 2019.

of shares is dependent upon WESCO's total stockholder return in relation to the total stockholder return of a select group of 
peer companies over a three-year period. The fair value of these awards is determined using a Monte Carlo simulation model. 
These awards are accounted for as awards with market conditions; compensation cost is recognized over the service period, 
regardless of whether the market conditions are achieved and the awards ultimately vest.

Vesting of the remaining 74,660 shares of performance-based awards in the table above is dependent upon the three-year 

average growth rate of WESCO's net income. The fair value of these awards is based upon the grant-date closing price of 
WESCO's common stock. These awards are accounted for as awards with performance conditions; compensation cost is 
recognized over the performance period based upon WESCO's determination of whether it is probable that the performance 
targets will be achieved.

WESCO INTERNATIONAL, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

From time to time, a number of lawsuits and claims have been or may be asserted against WESCO relating to the conduct of 

its business, including routine litigation relating to commercial and employment matters. The outcomes of litigation cannot be 
predicted with certainty, and some lawsuits may be determined adversely to WESCO. However, management does not believe 
that the ultimate outcome of any such pending matters is likely to have a material adverse effect on WESCO’s financial 
condition or liquidity, although the resolution in any fiscal period of one or more of these matters may have a material adverse 
effect on WESCO’s results of operations for that period.

WESCO is subject to the laws and regulations of states and other jurisdictions concerning the identification, reporting and 
escheatment (the transfer of property to the state) of unclaimed or abandoned funds, and is subject to audit and examination for 
compliance with these requirements. WESCO Distribution is currently undergoing a compliance audit in the State of Delaware 
concerning the identification, reporting and escheatment of unclaimed or abandoned property. A third party auditor is 
conducting the audit on behalf of the State, and the Company has been working with an outside consultant during the audit 
process and in discussions with the auditors. The Company is defending the audit, the outcome of which cannot be predicted 
with certainty at this time. After the third party auditor completes its field work, it is expected to issue preliminary findings for 
review by the Company and the State, and thereafter the auditor is expected to issue a final report of examination. If the 
Company and State do not reach resolution after further discussion, the State may issue a demand for payment, which the 
Company may either agree to pay or appeal, in full or in part. The Company has recorded a liability for unclaimed property 
based on the facts currently known to the Company.

In October 2014, WESCO was notified that the New York County District Attorney’s Office is conducting a criminal 
investigation involving minority and disadvantaged business contracting practices in the construction industry in New York 
City and that various contractors, minority and disadvantaged business firms, and their material suppliers, including the 
Company, are a part of this investigation. The Company intends to cooperate with the government investigation. The Company 
cannot predict the outcome or impact of the matter at this time, but could be subject to fines, penalties or other adverse 
consequences. Based on the facts currently known to the Company, it cannot reasonably estimate a range of exposure to 
potential liability at this time.  

14. SEGMENTS AND RELATED INFORMATION

Earnings per share (EPS) in each quarter is computed using the weighted-average number of shares outstanding during 
that quarter while EPS for the full year is computed by using the weighted-average number of shares outstanding 
during the year. Thus, the sum of the four quarters’ EPS may not equal the full-year EPS.

Diluted EPS in each quarter is computed using the weighted-average number of shares outstanding and common share 
equivalents during that quarter while Diluted EPS for the full year is computed by using the weighted-average number 
of shares outstanding and common share equivalents during the year. Thus, the sum of the four quarters’ Diluted EPS 
may not equal the full-year Diluted EPS.

On September 15, 2016, the Company completed the redemption of its 2029 Debentures. The redemption resulted in a 
non-cash charge of $123.9 million, which resulted in a net loss attributable to WESCO International, Inc. for 
the three months ended September 30, 2016. Accordingly, dilutive shares were not included in the calculation of 
diluted loss per share for the three months ended September 30, 2016 because their effect was antidilutive.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal 

financial officer, we conducted an evaluation of our disclosure controls and procedures (as defined in Exchange Act 
Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 
15d-15(f)). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our 
disclosure controls and procedures and internal control over financial reporting were effective as of the end of the period 
covered by this report.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as such 

term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Because of its inherent limitations, internal control over 
financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future 
periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of 
compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our 
management, including our principal executive officer and principal financial officer, we conducted an evaluation of the 
effectiveness of our internal control over financial reporting based on the updated framework in Internal Control — Integrated 
Framework (2013) (2013 Framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission on 
May 14, 2013. Based on our evaluation under the 2013 Framework, our management concluded that our internal control over 
financial reporting was effective as of December 31, 2016.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2016 has been audited by 

PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included 
herein.

Changes in Internal Control Over Financial Reporting

During the last fiscal quarter of  2016, there were no changes in the Company’s internal control over financial reporting 
identified in connection with management’s evaluation of the effectiveness of the Company’s internal control over financial 
reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over 
financial reporting.
