VALUE CREATION THROUGH 
INDUSTRY CONSOLIDATION
Scale is critical in distribution. Combining two industry 
powerhouses creates substantial value for our customers, 
supplier partners, investors, and employees, as well as the 
communities in which we operate. Through our aggressive 
integration efforts, we are accessing increased economies 
of scale, attracting and developing top talent, strengthening 
relationships with our preferred supplier partners, sharing 
complementary resources and capabilities, and providing 
our expanded portfolio of products, services and solutions 
to our global customers. We have mix-shifted our business 
into higher-growth end markets that provide very attractive 
secular growth into the future. Our industry leadership 
creates the opportunity to sustain growth over the long 
term and deliver superior returns. 

WESCO’s capabilities in industrial, construction, and utility 
matched with Anixter’s expertise in communications, 
security, and wire and cable create an industry-leading 
lineup for our customers. This business combination is 
more complementary than we expected, which speaks to 
even greater opportunities. The combined portfolio creates 
an efficient single‑source, or one‑stop‑shop, for all our 
customers’ needs. This translates into higher growth as we 
execute on our significant cross‑selling opportunities that 
enables us to offer more solutions to more customers in 
more locations around the world.

Before the acquisition of Anixter was completed last June, we 
began planning for the integration of these two leading B2B 
distribution companies. In addition to doubling our size, the 
transaction provides substantial cost and revenue synergies, 
expanded margins, improved working capital turns, and 
increased cash flow generation. From standing up a world‑
class Integration Management Office to rapidly closing the 
acquisition in a little more than five months, we’ve moved 
with speed and agility. We quickly selected and recruited our 
new senior management team and created our three new 
business segments — CSS (Communications and Security 
Solutions), EES (Electrical and Electronic Solutions), and UBS 
(Utility and Broadband Solutions). In the first six months of 
our 36-month integration plan, we’ve already increased our 
targeted cost synergy savings from $200 million to $250 
million. And, we have launched cross-selling and gross-margin 
improvement programs that will be key drivers of our long-
term, sustainable earnings power. I’m pleased to say that 
execution of our integration plan is off to an excellent start, 
and that we are exceeding our initial expectations. 

TO OUR 
SHAREHOLDERS, 
EMPLOYEES, 
AND BUSINESS 
PARTNERS

Last year was one of the most volatile and challenging years 
in history as we faced a worldwide pandemic and major 
economic dislocations, witnessed injustice and unrest, 
experienced a series of natural disasters, and managed 
significant shifts in the way we work, and in the way we live. 
Each of us experienced those challenges in a very personal 
way. Despite that unprecedented backdrop, we strengthened 
our company. I would like to express my deepest thanks and 
appreciation to WESCO’s 18,000 employees around the world 
for their unwavering dedication, determination and resilience. 
Our team is the best in the industry, and I am inspired by their 
exceptional service to our customers, supplier partners, and 
to each other every day. 

2020 will be remembered as WESCO’s watershed year. 
We completed the transformational acquisition of Anixter 
International Inc., doubling our size and forever changing our 
trajectory. The power of bringing WESCO and Anixter together 
is extraordinary. We are now the industry leader in electrical, 
communications, and utility distribution and supply chain 
solutions. Our differentiated scale and global capabilities offer 
unrivaled value for our customers and unique partnership 
value for our suppliers. The diversity of our expanded product 
and services portfolio, coupled with substantial integration 
synergies, supports sustainable earnings growth through the 
cycle. Our resilient free cash flow business model, as well as 
our proven ability to quickly deleverage, gives us the flexibility 
to continue to invest in our business. Our future is bright as 
we capitalize on our secular growth opportunities; unlock 
the power of our big data with advanced analytics, machine 
learning and artificial intelligence applications; and digitally 
transform our company and our industry.

 “Scale is critical in 
distribution. Combining 
two industry powerhouses 
creates substantial value 
for our customers, supplier 
partners, investors, and 
employees, as well as the 
communities in which 
we operate.”

NEW MISSION, VISION AND VALUES  
CHART OUR COURSE
Talent and culture ultimately determine our long-term 
success. We believe that we can do great things when we 
come together as one team with a shared mission, a clear 
vision and strategy, and values that bring out the best 
in us individually and collectively. The transformational 
combination of WESCO and Anixter provides us with the 
unique opportunity to draw from the best of each company 
in building our new “best of both” global enterprise. 

At WESCO, our mission is clear, we build, connect, power 
and protect the world. That is our purpose. It’s why we 
come to work, and it’s at the core of what our customers, 
suppliers and employees care deeply about. Our 18,000 
employees live that mission every day, as they service more 
than 125,000 customers, in over 50 countries around the 
world, from 800 branches, warehouses and sales offices.

Just as our mission defines what we do, our vision guides 
us to where we’re going. Our vision is to be the best tech- 
enabled supply chain solutions provider in the world. 
Our journey toward that vision constantly challenges the 
status quo as we seek to set a world-class standard for our 
products, services and supply chain solutions to create 
superior value for our customers.

Our mission and vision are guided by a set of core values: 

•  People first — as our talent is our greatest asset. 

•  One team — that values inclusion and diversity, where 

the best idea wins. 

•  Winning — with customers and suppliers, where we are 

committed to exceeding expectations. 

•  Being the best — and always acting with integrity while 

delivering superior results, and

• 

Innovating — with unrivaled focus and speed, as we 
digitally transform our business. 

Leading with these core values is a business imperative 
for us. They define our actions, and our actions define and 
differentiate us. Compelling values attract the best employees, 
and they sustain our customer and supplier relationships. 
Overall, they guide our efforts as we lead our industry and as 
we work on realizing our vision of becoming the best tech-
enabled supply-chain solutions provider in the world. 

We are proud to have been recognized by Fortune as one 
of the World’s Most Admired Companies in our industry, 
and by Forbes as one of America’s Best Employers for 
Women in 2020. We are also very pleased to be included in 
Bloomberg’s Gender Equality Index again this year. We’ve 
set a high bar for our new global enterprise, and our journey 
has only just begun.

SECULAR GROWTH TRENDS AND 
DIGITAL TRANSFORMATION  
DRIVE BREAKTHROUGH PERFORMANCE
The B2B wholesale distribution industry is rapidly evolving, 
driven by all things digital. Industries, like products and 
like companies, go through the classic s-curve cycle. 
Our B2B distribution value chain is entering the steep 
portion of this s-curve. As a result, fast-paced changes 
in technology, expanding digital tools and applications, 
new requirements and regulations in existing markets, 
and new market opportunities present outstanding 
future growth opportunities for our transformational 
combination of WESCO and Anixter. As we further integrate 
the two businesses and benefit from a best‑of‑the‑best 
organizational and cultural design, we are accelerating our 
digital transformation and taking a first‑mover advantage in 
employing digital technologies to fundamentally change how 
we operate, and how we deliver value to our customers.

Technology trends play an important role in our growth 
strategy. As products, systems, and IoT applications become 
more complex, supporting customers requires technical 
expertise and sales consultancy, which are key competitive 
differentiators for WESCO. By optimizing our customer and 
supplier data into actionable insights, we create value and 
transform our solution offerings. And, by integrating digital 
technology into all areas of our business, we change the way 
we operate by using agile development, design thinking, and 
human-centered design. Improved collaboration and resource 
management across our tech ecosystem, unlocking the 
power of our big data, and improving the experience at both 
ends of our value chain with customers and suppliers, drive 
multidimensional growth in support of our WESCO vision.

4  WESCO International, Inc.

With our new mission/vision/values and the integration of 
Anixter providing scale and scope benefits of 1+1=3, we are 
exceptionally well-positioned to capitalize on the secular 
growth opportunities in our higher growth end markets. 
Our three business segments are focused on delivering 
these above-market results:

CSS is using our global reach and technical expertise to 
capitalize on the strong demand for increased bandwidth due 
to higher voice, data, video and mobile usage, as well as the 
greater connectivity needs for remote work, home and school 
applications. These demand drivers are generating strong 
secular growth in data centers, mobility, secured networks, 
remote connectivity and audio/video applications.

EES is targeting growth driven by the increasing electrification 
of infrastructure and the industrial, transportation, and 
energy sectors. Importantly, we are also working with 
our customers and our suppliers to reduce greenhouse 
gas emissions and improve sustainability of the overall 
supply chain. 

UBS, as the leader in serving investor-owned utilities, 
public power, and utility contractors, is benefitting from 
increased investment in utility grid hardening and reliability, 
as well as in renewables and green energy investments. 
For Broadband, there is a heightened sense of urgency to 
provide reliable, high-speed internet to rural areas in the 
U.S. and Canada. This presents an excellent opportunity for 
WESCO to participate in the 5G buildout, as government 
investment and new technologies are being put in place.

In addition, an overall trend of supply chain consolidation and 
outsourcing, including relocation back to North America, is 
underway. Our customers want to reduce supply chain risk 
and do business with a smaller number of larger suppliers, 
and this bodes well for WESCO. To take advantage of all these 
robust secular growth trends, each of our three business 
segments is leveraging our combined and expanded portfolio 
of products, services and solutions. 

STRONG CASH FLOW GENERATION  
DELIVERS UPSIDE POTENTIAL
The foundation of a well-run distribution company is strong 
cash flow generation across all phases of the economic 
cycle. Earnings growth, along with effective working capital 
management and moderate capital investment needs, 
creates a cash flow business model that has proven resilient 
for us since going public 22 years ago. Last year, as the global 
pandemic adversely impacted demand, we delivered free 
cash flow of nearly $600 million by quickly and effectively 
managing our discretionary spending, working capital and 
capital investments. This total represents a full year of WESCO 

and just six months of Anixter cash flow, and it enabled us to 
reduce our financial leverage by nearly a half‑a‑turn since the 
acquisition closed in June 2020. Our top priority is to continue 
to reduce our debt in the short term and bring our leverage 
back within our target range. Once we have paid down the 
acquisition debt, our strong cash flow provides increased 
optionality to invest in further industry consolidation and 
above-market shareholder returns.

A NEW ERA
As I look ahead, I’m confident that WESCO is investing in 
the right areas, at the right time. We are deepening our 
competitive advantage and setting the foundation for long-
term, profitable growth. At the same time, we are committed 
to responsible ESG (Environmental, Social, and Governance) 
operating practices, using our scale and resources to drive 
a better, more sustainable future for all our stakeholders. 
By focusing on building our culture of excellence, inclusion, 
and continuous improvement, we have the capabilities to 
execute positive change. 

It’s an exciting and defining moment in our history, and the 
start of a new era for WESCO. With 2020 behind us, we look 
to the future with great expectations and great conviction in 
our capabilities. The transformational combination of WESCO 
and Anixter has established us as the industry leader. As 
a combined company, we are bigger, stronger, and better 
together. We are moving forward from a position of strength, 
intent on leading not only the digital transformation of our 
business but also the digital transformation of our industry. 
This will become our primary competitive advantage and 
differentiator in the years ahead. We have begun our journey 
of becoming the best tech-enabled supply chain solutions 
provider in the world. 

THANK YOU
On behalf of our WESCO Board of Directors, our entire 
leadership team, and our 18,000 associates around the 
world, thank you for your investment in WESCO. We remain 
fully committed to doing all we can to build long-term value 
creation for you and all those connected to our business.

Very best regards,

John J. Engel 
Chairman, President and Chief Executive Officer

Item 1. Business.

PART I

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")  and  its  subsidiaries  (collectively,  “WESCO”  or  the  "Company"), 
headquartered  in  Pittsburgh,  Pennsylvania,  is  a  leading  provider  of  business-to-business  distribution,  logistics  services  and 
supply chain solutions.

On  June  22,  2020,  WESCO  completed  its  previously  announced  acquisition  of  Anixter  International  Inc.,  a  Delaware 
corporation  (“Anixter”).  Pursuant  to  the  terms  of  the  Agreement  and  Plan  of  Merger,  dated  January  10,  2020  (the  “Merger 
Agreement”),  by  and  among  Anixter,  WESCO  and  Warrior  Merger  Sub,  Inc.,  a  Delaware  corporation  and  a  wholly  owned 
subsidiary of WESCO (“Merger Sub”), Merger Sub was merged with and into Anixter (the “Merger”), with Anixter surviving 
the Merger and continuing as a wholly owned subsidiary of WESCO. On June 23, 2020, Anixter merged with and into Anixter 
Inc., with Anixter Inc. surviving to become a wholly owned subsidiary of WESCO.

As  a  result  of  the  Merger,  the  Company  now  employs  nearly  18,000  people,  maintains  relationships  with  approximately 
30,000 suppliers, and serves more than 125,000 customers worldwide. With nearly 1,500,000 products, end-to-end supply chain

Business Segments and Industry Overview

As  a  result  of  the  Merger,  the  Company  now  has  operating  segments  organized  around  three  strategic  business  units 
consisting  of  Electrical  &  Electronic  Solutions  ("EES"),  Communications  &  Security  Solutions  ("CSS")  and  Utility  and 
Broadband Solutions ("UBS").

The following is a description of each of the Company's reportable segments and their business activities.

Electrical & Electronic Solutions

The EES segment, with sales in approximately 40 countries, supplies a broad range of products and supply chain solutions 
primarily  to  the  construction,  industrial  and  original  equipment  manufacturer  ("OEM")  markets.  Construction  and  industrial 
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, wastewater treatment facilities, data centers, security installations, offices, and modular and mobile homes. 
OEM customers require products used in the manufacturing of automotive, industrial, medical, transportation, marine, military 
and communications  equipment. The product portfolio in this  global business  includes a  broad range of electrical equipment 
and supplies, wire and cable, 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. The EES segment operates in highly fragmented markets that include thousands of 
small regional and locally based, privately owned competitors as well as several large, multi-national companies. EES includes 
the “Electrical and Electronic Solutions” business acquired from Anixter and the majority of the legacy WESCO industrial and 
construction businesses.

Communications & Security Solutions

The CSS segment is a global leader in the network infrastructure and security markets, with sales to customers across North 
America, Europe, the Middle East, Latin America and the Asia Pacific region. The network infrastructure market is comprised 
of data centers, wireless products and other devices that enable network connectivity and communication. The security market 
includes video surveillance, fire and intrusion detection, access control and other solutions to maintain protection and safety for 
customers.  Both  the  network  infrastructure  and  security  businesses  are  large,  fragmented  and  diverse  markets  which  include 
various  industry  groups  such  as  technology,  finance,  telecommunications  service  providers,  transportation,  education, 
government,  healthcare  and  retail.  CSS  sells  products  directly  to  end  users  or  through  various  channels  including  data 
communications  contractors,  security,  network,  professional  audio/visual  and  systems  integrators.  CSS  has  a  broad  product 
portfolio that includes copper and fiber optic cable and connectivity, access control, video surveillance, intrusion and fire/life 
safety,  cabinets,  power,  cable  management,  wireless,  professional  audio/video,  voice  and  networking  switches  and  other 
ancillary  products.  In  addition,  CSS  offers  a  variety  of  value-added  supply  chain  solutions  such  as  inventory  management, 
product  packaging  and  enhancement,  and  customized  supply  chain  services.  CSS  includes  the  “Network  and  Security 
Solutions” business acquired from Anixter and the legacy WESCO data communications and safety businesses.

Utility & Broadband Solutions

The  UBS  segment,  with  operations  primarily  in  the  U.S.  and  Canada,  supplies  electrical  transmission  and  distribution 
products, power plant maintenance, repair and operations supplies and smart-grid products, and arranges materials management 
and  procurement  outsourcing  for  the  power  generation,  power  transmission  and  electricity  distribution  industries.  The  UBS 
segment  also  provides  value-added  safety  and  technology  solutions,  which  are  essential  to  utility  customers.  UBS  customers 
include  investor-owned  utilities,  public  power  companies,  and  contractors  that  serve  these  customers.  Investor-owned  utility 
companies  provide  a  combination  of  electric  generation,  transmission  and/or  distribution  and  are  owned  by  investors  or 
shareholders while public power entities are generally non-profit entities owned by their members or governed by local, state 
and municipal governments. These two markets serve the vast majority of utility customers in the U.S. and Canada. The UBS 
segment provides critical components within the core functions of generating, transmitting and distributing electricity. Products 
include conductors such as wire and cable, transformers, overhead transmission and distribution hardware, switches, protective 
devices and underground distribution, connectors used in the construction or maintenance and repair of electricity transmission 
and substation distribution infrastructure and supplies, lighting and conduit used in non-residential and residential construction. 
The UBS segment combines the “Utility Power Solutions” business acquired from Anixter, the legacy WESCO utility business, 
the legacy WESCO broadband business and the legacy WESCO integrated supply business.

Segments" to the Notes to Consolidated Financial Statements.

Business Strategy

We partner with suppliers to transform products and services into cost-effective, innovative supply chain solutions. We help 
our  customers  build,  connect,  power  and  protect  their  businesses  to  improve  their  operations  and  the  world  we  live  in.  We 
generate  significant  operating  cash  flow,  which  is  deployed  to  fund  organic  growth  opportunities,  acquire  companies  that 
provide  new  capabilities  for  growth  and  manage  our  capital  structure.  Additionally,  over  the  past  several  years,  we  have 
returned cash to stockholders through share repurchases. With our broad portfolio of products, extensive services and insights 
from data analysis, we expect to grow sales at a faster rate than the industry.

We utilize LEAN continuous improvement initiatives to deliver commercial and operational excellence, and we extend our 

LEAN initiatives to customers to improve the efficiency and effectiveness of their operations and supply chains.

Our strategies align around the following six planks, each of which is comprised of a series of initiatives. We expect these 
initiatives  to  enable  us  to  meet  the  current  and  future  needs  of  our  customers,  grow  our  business,  and  drive  value  for  our 
shareholders.

Competitive Strengths

The competitive environment is highly fragmented with hundreds of distributors and manufacturers selling products directly 
or through multiple distribution channels to end users or other resellers. There is significant competition within each end market 
and geographic area served that creates pricing pressure and the need for excellent service. Competition is generally based on 
product  line  breadth,  product  availability,  service  capabilities,  geographic  proximity  and  price.  We  believe  that  our  broad 
portfolio of products, customer centered approach, global reach with local expertise, comprehensive value-added services and 
smart, digital solutions provide distinct competitive advantages.

Broad Portfolio of Products. We partner with industry-leading suppliers to deliver the most trusted brands in the industry. 
Our  broad  product  offering  encompasses  automation,  broadband,  communications,  electrical,  electronics,  energy,  lighting, 
MRO, networking, renewables, safety, security, utility and wire and cable.

Customer  Centered  Approach.  Each  of  our  customers  have  unique  business  models,  challenges  and  priorities.  Our 
dedicated technical experts have extensive experience and product knowledge and are committed to providing solutions tailored 
to their unique needs. With specialized industry knowledge and a focus on the latest technologies, we help design and deploy 
solutions that address top business priorities.

Global Reach with Local Expertise. Our international operations and global sourcing capabilities enable us to service our 
customers wherever they may need us. WESCO has approximately 800 branches, warehouses and sales offices with operations 
in more than 50 countries. Our global distribution network includes 42 facilities that operate as regional distribution centers or 
large branch locations in key geographic areas in North America, Europe and Latin America. These facilities add value for our 
customers  and  suppliers  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  global  network  allows  us  to  enhance  local  customer 
service by tailoring individual branch products and services to local customer needs.

Comprehensive  Value-Added  Services.  We  provide  a  wide  range  of  value-added  services,  which  draw  on  our  product 
knowledge  and  logistics  expertise,  to  enable  our  customers  to  save  time,  improve  productivity,  mitigate  risk  and  increase 
profitability.  Our  broad  service  offering  includes  installation  enhancement,  materials  management,  kitting  and  labeling, 
extensive MRO solutions, onsite job trailer solutions, end-to-end supply chain management and project management/execution 
across the project lifecycle.

Smart,  Digital  Solutions.  Our  Silicon  Valley  innovation  center  and  partnerships  with  industry-leading  technology 
companies  bring  unique  capabilities  in  digital  and  information-based  solutions.  These  solutions  include  global  e-commerce 
platforms,  vendor  managed  inventory,  point  of  use  systems,  last  mile  optimization,  supply  chain  engineering  and  intelligent 
automation. From enterprise-wide connectivity to real-time analytics and reporting, our digital ecosystem supports all business 
needs.

Geography

Our network of branches, warehouses and sales offices consists of 506 locations in the U.S., 154 in Canada, 60 in Europe 
and the Middle East, 59 in Latin America and 38 in the Asia Pacific region. This includes 42 facilities that operate as regional 
distribution centers or large branch locations, of which 33 are located in the U.S., six are in Canada, two are in Europe and one 
is  in  Latin  America.  We  also  sell  to  global  customers  through  sales  offices  and  branch  operations  in  various  locations 
throughout Europe, the Middle East, Latin America and the Asia Pacific region.

Human Capital

At  WESCO,  our  people  and  our  high-performance  culture  are  our  greatest  assets.  We  are  committed  to  continuous 
improvement  and  leveraging  our  diverse  and  talented  workforce  in  pursuing  WESCO’s  vision  to  be  the  best  tech-enabled 
supply chain solutions provider in the world.

The merger of WESCO and Anixter doubled the Company’s revenue, and significantly increased our employee headcount 
and  global  footprint,  including  the  number  of  countries  in  which  we  operate.  As  of  December  31,  2020,  the  Company  had 
nearly  18,000  full-time  employees  worldwide,  with  more  than  12,000  in  the  U.S.  and  approximately  5,800  in  international 
locations.

Compensation  and  Benefits  Program.  WESCO  provides  competitive  compensation  and  benefits  packages  in  each  of  our 
locations around the globe. In the U.S., we provide a comprehensive benefits program that offers choices to fit our employees’ 
diverse  needs  including  health  and  disability  benefits,  paid  time-off,  life  insurance,  retirement  programs,  and  access  to  other 
services that support health and wellness. We also have an employee assistance program available to our employees and their 
family members.

Inclusion  and  Diversity.  As  part  of  WESCO's  integration  with  Anixter,  we  conducted  a  company-wide  culture  survey  to 
give all employees a voice in actively shaping the values that will define the combined organization, one of which is inclusion 
and  diversity.  The  goals  of  WESCO’s  Inclusion  and  Diversity  program  are  to  1)  leverage  the  unique  experiences  and 
perspectives  of  our  talented  workforce  to  support  WESCO’s  mission,  2)  further  engage  employees  and  build  an  inclusive 
culture, 3) recruit and develop talent that bring new perspectives and thought processes to WESCO, 4) increase representation 
of  suppliers  that  are  owned  and  operated  by  teams  with  diverse  backgrounds  and  5)  support  the  communities  in  which  we 
operate.

WESCO  has  established  an  Inclusion  &  Diversity  Council  comprised  of  members  of  our  senior  management  to  lead  the 
formation  of  four  Business  Resource  Groups  (“BRGs”)  that  will  support  four  identity  groups  –  women,  BIPOC  (Black, 
Indigenous, and People of Color), LGBTQ+, and veterans of the armed forces. These BRGs foster a sense of community and 
inclusion,  provide  opportunities  to  network,  support  advancement  opportunities  within  the  organization,  and  assist  with 
recruiting. The BRGs are global and open to all employees regardless of any aspect of their personal identity.

WESCO has  established relationships with several  charitable organizations  and  encourages employees to volunteer in  the 
community  by  providing  one  day  of  paid  volunteer  time  per  year.  By  connecting  with  and  contributing  to  local  charitable 
organizations, WESCO supports the development of strong, vibrant and diverse communities.

Safety. Safety is a core value of WESCO and we do not tolerate violations of established safety protocol. We are committed 
to  reducing  or  eliminating  health  and  safety  risks  through  dedicated  programs,  leadership  commitment,  and  employee 
involvement. We seek to achieve continuous improvement in the safety of our facilities and injury-leading injury rates.

In  response  to  the  COVID-19  pandemic,  we  implemented  significant  operating  changes  to  ensure  a  safe  operating 
environment for our employees, and to protect the communities in which we operate. As an essential business, substantially all 
of our distribution facilities remained open and we implemented additional safety measures for employees doing critical on-site 
work and required all other employees to work remotely.

Training and Development. WESCO offers several certification and training programs, some of which are required for all 
employees while others are voluntary or based on job role. The Company offers a tuition reimbursement program to eligible 
employees to encourage the pursuit of undergraduate and graduate education to prepare employees for expanded roles in the 
business.

The  Company  has  had  a  sales  development  training  program  in  place  for  over  ten  years.  The  program  is  designed  to 
systematically  train  and  develop  new  college  graduates  through  on-the-job  rotations  and  cohort  learning  and  development 
during the first year of employment. Graduates of the program move into various sales and operations roles after completing the 
one-year  program.  The  Company  also  sponsors  a  summer  internship  program  to  provide  college  students  with  real  work 
experience and give them the opportunity to evaluate different career fields.

Intellectual Property

We  protect  our  intellectual  property  through  a  combination  of  trademarks,  patents  and  trade  secrets,  foreign  intellectual 
property laws, confidentiality procedures and contractual provisions. We currently have trademarks, patents and service marks 
registered  with  the  U.S.  Patent  and  Trademark  Office  and  in  various  other  countries.  The  trademarks  and  service  marks 
registered  in  the  U.S.  include,  among  others:  “WESCO®”,  our  corporate  logo  and  the  running  man  logo.  The  Company's 
"Anixter"  trademark  is  registered  in  the  U.S.  and  various  foreign  jurisdictions  and  its  "EECOL"  trademark  is  registered  in 
Canada.  We  have  also  applied  to  register  international  trademarks,  patents,  and  service  mark  applications  in  various  foreign 
jurisdictions. While our patents have value, none is so essential that its loss would materially affect our business.

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.

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.

Risks Related to Our Acquisitions, Divestitures and Strategic Initiatives

We may not be able to fully realize the anticipated benefits and cost savings of our merger with Anixter.

On June 22, 2020, we completed our merger with Anixter. The success of the merger, including anticipated benefits and cost 
savings, depends on the successful combination and integration of the companies’ businesses. It is possible that the integration 
process could result in the loss of key employees, higher than expected costs, diversion of management attention, the disruption 
of either company’s ongoing legacy businesses or inconsistencies in standards, controls, procedures and policies that adversely 
affect  the  combined  company’s  ability  to  maintain  relationships  with  customers,  suppliers  and  employees  or  to  achieve  the 
anticipated benefits and cost savings of the merger.

We  have  incurred,  and  expect  to  continue  to  incur,  a  number  of  non-recurring  costs  associated  with  the  merger  and 
combining  the  operations  of  the  two  companies.  This  includes  transaction  fees  and  expenses  related  to  formulating  and 
implementing  integration  plans,  including  facilities,  systems  consolidation  and  employment-related  costs.  We  continue  to 
assess the magnitude of these costs, and additional unanticipated costs may be incurred in the integration of the two companies’ 
businesses. Although we expect that the elimination of duplicative costs, as well as the realization of other efficiencies related 
to  the  integration  of  the  businesses,  should  allow  us  to  offset  integration-related  costs  over  time,  this  net  benefit  may  not  be 
achieved in the near term, or at all.

If we experience difficulties with the integration process, the anticipated benefits of the merger may not be realized or may 
take longer to realize than expected. These integration matters could have an adverse effect on us for an undetermined period. 
In addition, the actual cost savings of the merger could be less than anticipated.

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.

We have invested significantly in expanding our e-commerce capabilities and online customer experience. If our efforts to 
expand our capabilities in this area are 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. Furthermore, 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.

Our  strategic  and  operational  initiatives  are  subject  to  various  risks  and  uncertainties,  and  we  may  be  unable  to 
implement the initiatives successfully.

We  are  engaged  in  a  number  of  strategic  and  operational  initiatives  designed  to  optimize  costs  and  improve  operational 
efficiency. Our ability to successfully execute these initiatives is subject to various risks and uncertainties and there can be no 
assurance regarding the timing of or extent to which we will realize the anticipated benefits, if at all.

Any future acquisitions that we may undertake will involve a number of inherent risks, any of which could cause us not 
to realize the anticipated benefits.

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 a business or assets.

Risks Related to the Global Macroeconomic Environment and Our International Operations

Our global operations expose us to political, economic, legal , currency and other risks.

We  operate  a  network  of  approximately  800  branches,  warehouses  and  sales  offices  with  operations  in  more  than  50 
countries. Approximately one-third of our employee population are non-U.S. employees. We derive approximately 26% of our 
revenues  from  sales  outside  of  the  U.S.  As  a  result,  we  are  subject  to  additional  risks  associated  with  owning  and  operating 
businesses in these foreign markets and jurisdictions.

Operating in the global marketplace exposes us to a number of risks including: 

•

•
•

•

•
•
•

•

geopolitical  and  security  issues,  such  as  armed  conflict  and  civil  or  military  unrest,  political  instability,  terrorist 
activity and human rights concerns, and
natural disasters and public health crises, including pandemics such as COVID-19, and other catastrophic events;
global  supply  chain  disruptions  and  large-scale  outages  or  inefficient  provision  of  services  from  utilities, 
transportation, data hosting, or telecommunications providers;
abrupt changes in government policies, laws, regulations or treaties, including imposition of export, import, or doing-
business regulations, trade sanctions, embargoes or other trade restrictions;
tax or tariff increases;
government restrictions on, or nationalization of, our operations in any country;
changes in labor conditions and difficulties in staffing and managing international operations, including logistical and 
communication challenges;
restrictions on currency movement;

challenges in protecting our IP rights in certain countries;
local business and cultural factors that differ from our current standards and practices;
continuing uncertainty regarding social, political, immigration, and tax and trade policies in the U.S. and abroad;
currency exchange rate fluctuations; and
other social, political and economic instability, including recessions and other economic crises in other regions.

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

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  may  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. Although no single customer accounts for more than 2% of our sales, a payment default 
by  one  of  our  larger  customers  could  have  a  negative  short-term  impact  on  earnings  or  liquidity.  A  financial  or  industry 
downturn could have an adverse effect on the collectability of our accounts receivable, which could result in longer payment 
cycles,  increased  collection  costs  and  defaults.  Should  one  or  more  of  our  larger  customers  declare  bankruptcy,  it  could 
adversely affect the collectability of our accounts receivable, along with credit loss 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 may also affect our business and financial condition in ways that we currently cannot predict, and 
there can be no assurance that economic and political instability, both domestically and internationally (for example, resulting 
from changes to trade policies, tariffs or participation in trade agreements or economic and political unions) will not adversely 
affect our results of operations, cash flows or financial position in the future.

Our business and operations have been and will continue to be adversely affected by the COVID-19 pandemic, and the 
duration and extent to which it will affect our business, financial condition, results of operations, cash flows, liquidity, 
and stock price remains uncertain.

The  global  COVID-19  pandemic  has  created  significant  disruption  to  the  broader  economies,  financial  markets, 
workforces,  business  environment,  and  our  suppliers  and  customers.  It  began  to  adversely  affect  our  business,  results  of 
operations,  and  financial  condition  late  in  the  first  quarter  of  2020  and  is  continuing,  and  the  effects  include  lost  or  delayed 
revenue  to  us.  The  pandemic  has  caused  significant  disruptions  to  our  business  due  to,  among  other  things,  reduced 
transportation, restrictions on travel, disruptions to our suppliers and global supply chain, the impact on our customers and their 
demand  for  our  products  and  services  and  ability  to  pay  for  them,  as  well  as  temporary  closures  of  facilities.  Some  of  the 
actions we have taken in response to the COVID-19 pandemic, such as implementing remote working arrangements, may also 
create increased vulnerability to cybersecurity incidents and other risks.

The duration and extent to which the COVID-19 pandemic will continue to impact our business, results of operations, and 
financial condition depends on many evolving factors and future developments for which there is significant uncertainty, such 
as  the  severity  and  transmission  rate  of  the  virus,  governmental,  business  and  individuals'  actions  taken  in  response,  the 
development and availability of effective treatment or vaccines, the extent and effectiveness of containment actions, as well as 
the  matters  noted  above.  In  addition,  the  COVID-19  pandemic  may  continue  to  adversely  affect  many  of  our  suppliers’  and 
customers' businesses and operations, including the ability of our suppliers to manufacture or obtain the products we sell or to 
meet delivery requirements and commitments, and our customers’ demand for our products and services and the ability to pay 
for them, all of which could adversely affect our sales and results of operations.

While we are supporting essential businesses and our branch locations have remained operational consistent with existing 
governmental and public health authority directives to date, there is significant uncertainty as to what steps we may need to take 
in response to the pandemic in the future (including in response to any new health and safety measures or restrictions), and what 
impact they will have on our business and operations. We have taken actions to reduce costs and cash expenditures, including 
reductions in administrative expenses, payroll and benefits, capital expenditures, and other costs, and further steps may become 
necessary in the future. Due to the uncertainty of COVID-19, we will continue to assess the situation, including the impact of 
governmental regulations or restrictions that might be imposed or re-imposed in response to the pandemic. If we are unable to 
appropriately  respond  to  or  manage  the  impact  of  these  events,  our  business  and  results  of  operations  may  be  adversely 
affected.

Table of Contents

In addition, the impact of COVID-19 on macroeconomic conditions has adversely affected and may continue to affect the 
functioning of financial and capital markets, foreign currency exchange rates, commodity and energy prices, and interest rates. 
Even after the COVID-19 pandemic subsides, we may continue to experience adverse impacts to our business as a result of any 
economic  recession  or  depression  that  has  or  may  occur.  The  long-term  financial  and  economic  impacts  of  the  COVID-19 
pandemic may continue for a significant period and cannot be reliably quantified or estimated at this time due to the uncertainty 
of these future developments.

Any of these events could materially adversely affect our business, financial condition, results of operations, cash flows, 

liquidity and stock price.

We are subject to various laws and regulations globally and any failure to comply could adversely affect our business.

We are subject to a broad range of laws and regulations in the jurisdictions where we operate globally, including, among 
others,  those  relating  to  data  privacy  and  protection,  cyber  security,  import  and  export  requirements,  anti-bribery  and 
corruption,  product  compliance,  supplier  regulations  regarding  the  sources  of  supplies  or  products,  environmental  protection, 
health  and  safety  requirements,  intellectual  property,  foreign  exchange  controls  and  cash  repatriation  restrictions,  labor  and 
employment,  e-commerce,  advertising  and  marketing,  anti-competition  and  tax.  Compliance  with  these  domestic  and  foreign 
laws, regulations and requirements may be burdensome, increasing our cost of compliance and doing business. In addition, as a 
supplier to federal, state, and local government agencies, we must comply with certain laws and regulations relating specifically 
to our governmental contracts. Although we have implemented policies and procedures designed to facilitate compliance with 
these laws, we cannot assure you that our employees, contractors, or agents will not violate such laws and regulations, or our 
policies  and  procedures.  Any  such  violations  could  result  in  the  imposition  of  fines  and  penalties,  damage  to  our  reputation, 
and, in the case of laws and regulations relating to governmental contracts, the loss of those contracts.

Fluctuations in foreign currency have an effect on our 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.  We  may  incur  losses 
related  to  foreign  currency  fluctuations,  and  foreign  exchange  controls  may  prevent  us  from  repatriating  cash  in  countries 
outside the U.S. In addition, because our financial statements are stated in U.S. dollars, such fluctuations may also affect the 
comparability of our results between financial periods.

Risks Related to Our Information Systems and Technology

Any  significant  disruption  or  failure  of  our  information  systems,  could  lead  to  interruptions  in  our  operations,  which 
may materially adversely affect our business operations, financial condition, and 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. We rely on the proper functioning and availability of 
our  information  systems  to  successfully  operate  our  business,  including  managing  inventory,  processing  customer  orders, 
shipping products and providing service to customers, and compiling financial results. 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. Any significant or prolonged unavailability or failure of 
our  critical  information  systems  could  materially  impair  our  ability  to  maintain  proper  levels  of  inventories,  process  orders, 
meet the demands of our customers in a timely manner, and other harmful effects. 

We seek to continually enhance our information systems, and such changes could potentially create a disruption or failure of 
our existing information technology. Conversions to new information technology systems may result in cost overruns, delays or 
business  interruptions.  Additionally,  efforts  to  align  portions  of  our  business  on  common  platforms,  systems  and  processes 
could result in unforeseen interruptions, increased costs or liability, and other negative effects. If our information technology 
systems are disrupted, become obsolete or do not adequately support our strategic, operational or compliance needs, it could 
result in a competitive disadvantage or adversely affect our business operations and financial condition, including our ability to 
process  orders,  receive  and  ship  products,  maintain  inventories,  collect  accounts  receivable  and  pay  expenses,  therefore 
impacting our results of operations.

We  may  experience  a  failure  in  or  breach  of  our  information  security  systems,  or  those  of  our  third-party  service 
providers, as a result of cyber-attacks or information security breaches.

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 seek to gain to access our systems and networks, or those of 
our third-party service providers. Additionally, third parties may fraudulently attempt to induce employees or customers into 
disclosing sensitive information such as user names, passwords and other information in order to gain access to our customers’ 
data or our data, including our intellectual property and other confidential business information, or our information technology 
systems.  Information technology security threats to our systems, networks and data have dramatically increased in recent years 
due the proliferation of new technologies and the increased sophistication and activities of perpetrators. These threats pose a 
risk  to  the  security  of  our  systems  and  networks  and  the  confidentiality,  availability  and  integrity  of  our  proprietary  and 
confidential information.

Although we actively manage information technology security risks within our control and continually seek to enhance our 
controls  and  processes  designed  to  protect  our  systems,  computers,  networks  and  data,  there  can  be  no  assurance  that  such 
actions  will  be  sufficient  to  mitigate  all  potential  risks.   As  cyber  threats  continue  to  evolve,  we  may  be  required  to  expend 
additional  resources  to  continue  to  enhance  our  information  security  measures  and  remediate  any  information  security 
vulnerabilities.  Despite  the  precautions  we  take  to  mitigate  the  risks  of  such  events,  an  attack  on  our  enterprise  information 
technology system, or those of third parties with which we do business, could result in theft or unauthorized disclosure of our 
proprietary  or  confidential  information  or  a  breach  of  confidential  customer,  supplier  or  employee  information.  Such  events 
could impair our ability to conduct our operations, which could have an adverse impact on revenue and harm our reputation. 
Additionally, such an event could expose us to regulatory sanctions or penalties, lawsuits or other legal action or cause us to 
incur legal liabilities and costs, which could be significant, in order to address and remediate the effects of an attack and related 
security  concerns.  The  insurance  coverage  we  maintain  may  be  inadequate  to  cover  claims  or  liabilities  relating  to  a 
cybersecurity attack.

In addition, the legal and regulatory environment surrounding information security and privacy in the U.S. and international 
jurisdictions  is  constantly  evolving.  Violation  or  non-compliance  with  any  of  these  laws  or  regulations,  contractual 
requirements  relating  to  data  security  and  privacy,  or  our  own  privacy  and  security  policies,  either  intentionally  or 
unintentionally, or through the acts of intermediaries could have a material adverse effect on our brand, reputation, business, 
financial condition and results of operations, as well as subject us to significant fines, litigation losses, third-party damages and 
other liabilities.

Risks Related to Our Industry, Markets and Business Operations 

Loss of key suppliers could decrease sales, profit margins, and earnings.

Most of our agreements with suppliers are terminable by either party on 60 days' notice or less for any reason. We currently 
source products from thousands of suppliers. However, our 10 largest suppliers in 2020 accounted for approximately 30% of 
our purchases by annual dollar volume for the period. 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  reduce  its  reliance  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. 
Although we believe our relationships with our key suppliers are good, they could change their strategies as a result of a change 
in control, expansion of their direct sales force, changes in the marketplace or other factors beyond our control, including a key 
supplier becoming financially distressed. 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,  natural  disasters,  outbreaks  of  disease,  information  system  disruptions  or  other  reasons 
beyond our control.

Table of Contents

Product cost fluctuations, lack of product availability, or inefficient supply chain operations could decrease sales, profit 
margins, and earnings.

Some 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.  Declines  in  oil  and  natural  gas  prices  can  negatively  impact  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, decrease sales, profit margins and 
earnings, which could adversely affect our business.

A decline in project volume could adversely affect our sales and earnings.

While much of our sales and earnings are generated by comparatively smaller and more frequent orders, the fulfillment of 
large  orders  for  large  capital  projects  generates  significant  sales  and  earnings.  Accordingly,  our  results  of  operations  can 
fluctuate depending on whether and when large project awards occur and the commencement and progress of work under large 
contracts already awarded.

The awarding and timing of projects is unpredictable and depends on many factors outside of our control. Project awards 
often involve complex and lengthy negotiations and competitive bidding processes. These processes can be impacted by a wide 
range of factors including a customer’s decision to not proceed with a project or its inability to obtain necessary governmental 
approvals or financing, commodity prices,  and overall market  and economic conditions.  Slow macro-economic growth rates, 
difficult  credit  market  conditions  for  our  customers,  weak  demand  for  our  customers’  products  or  other  customer  spending 
constraints  can  result  in  project  delays  or  cancellations.  In  addition,  some  our  competitors  may  also  be  more  willing  to  take 
greater or unusual risks or include terms and conditions in a contract that we might not deem acceptable.

We have risks associated with the sale of nonconforming products and services.

Historically,  we  have  experienced  a  small  number  of  cases  in  which  our  vendors  supplied  us  with  products  that  did  not 
conform  to  the  agreed  upon  specifications  without  our  knowledge.  Additionally,  we  may  inadvertently  sell  a  product  not 
suitable for a customer’s application. We address this risk through our quality control processes, by seeking to limit liability and 
our  warranty  in  our  customer  contracts,  by  obtaining  indemnification  rights  from  vendors  and  by  maintaining  insurance 
responsive to these risks. However, there can be no assurance that we will be able to include protective provisions in all of our 
contracts, that vendors will have the financial capability to fulfill their indemnification obligations to us, or that insurance can 
be obtained with sufficiently broad coverage or in amounts sufficient to fully protect us.

Disruptions to our logistics capability or supply chain may have an adverse impact on our operations.

Our global logistics services are operated through distribution centers around the world. 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.  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  that  we  have  concluded  are  most  likely  to  occur.  Furthermore,  although  our  reviews  have  led  to  more  systematic 
contingency planning, our plans are in varying stages of development and execution, such that they may not be adequate at the 
time of occurrence for the magnitude of any particular disaster event that we may encounter.

We  also  depend  on  transportation  service  providers  for  the  delivery  of  products  to  our  customers.  Any  significant 
interruption  or  disruption  in  service  at  one  or  more  of  our  distribution  centers  due  to  severe  weather,  natural  disasters, 
information technology upgrades, operating issues, disruptions to our transportation network, public heath crises, pandemics or 
other  unanticipated  events,  could  impair  our  ability  to  obtain  or  deliver  inventory  in  a  timely  manner,  cause  cancellations  or 
delays in shipments to customers or otherwise disrupt our normal business operations.

margins, and earnings.

Some 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.  Declines  in  oil  and  natural  gas  prices  can  negatively  impact  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, decrease sales, profit margins and 

earnings, which could adversely affect our business.

A decline in project volume could adversely affect our sales and earnings.

While much of our sales and earnings are generated by comparatively smaller and more frequent orders, the fulfillment of 

large  orders  for  large  capital  projects  generates  significant  sales  and  earnings.  Accordingly,  our  results  of  operations  can 

fluctuate depending on whether and when large project awards occur and the commencement and progress of work under large 

contracts already awarded.

The awarding and timing of projects is unpredictable and depends on many factors outside of our control. Project awards 

often involve complex and lengthy negotiations and competitive bidding processes. These processes can be impacted by a wide 

range of factors including a customer’s decision to not proceed with a project or its inability to obtain necessary governmental 

approvals or financing, commodity prices, and overall market  and economic conditions.  Slow macro-economic growth  rates, 

difficult  credit  market  conditions  for  our  customers,  weak  demand  for  our  customers’  products  or  other  customer  spending 

constraints  can  result  in  project  delays  or  cancellations.  In  addition,  some  our  competitors  may  also  be  more  willing  to  take 

greater or unusual risks or include terms and conditions in a contract that we might not deem acceptable.

We have risks associated with the sale of nonconforming products and services.

Historically,  we  have  experienced  a  small  number  of  cases  in  which  our  vendors  supplied  us  with  products  that  did  not 

conform  to  the  agreed  upon  specifications  without  our  knowledge.  Additionally,  we  may  inadvertently  sell  a  product  not 

suitable for a customer’s application. We address this risk through our quality control processes, by seeking to limit liability and 

our  warranty  in  our  customer  contracts,  by  obtaining  indemnification  rights  from  vendors  and  by  maintaining  insurance 

responsive to these risks. However, there can be no assurance that we will be able to include protective provisions in all of our 

contracts, that vendors will have the financial capability to fulfill their indemnification obligations to us, or that insurance can 

be obtained with sufficiently broad coverage or in amounts sufficient to fully protect us.

Our global logistics services are operated through distribution centers around the world. An interruption of operations at

other  unanticipated  events,  could  impair  our  ability  to  obtain  or  deliver  inventory  in  a  timely  manner,  cause  cancellations  or 

delays in shipments to customers or otherwise disrupt our normal business operations.

Product cost fluctuations, lack of product availability, or inefficient supply chain operations could decrease sales, profit 

An increase in competition could decrease sales, profit margins, and earnings.

Table of Contents

We operate in a highly competitive industry and compete directly with global, national, regional and local providers of like 
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.  We  may  be  subject  to  supplier  price 
increases  while  not  being  able  to  increase  prices  to  customers.  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. These factors, in addition to competitive pressures resulting from the 
fragmented nature of our industry, could affect our sales, profit margins and earnings.

Risks Related to Tax Matters

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  of  operations.  Changes  in  the  tax  law  at  the  federal  and  state/provincial  levels,  in  particular  in  the  U.S.  and 
Canada, can have a material adverse effect on our results of operations.

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 sometimes 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, which 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 U.S., we may have to repatriate funds from overseas, which would result in additional income taxes being 
incurred on the amount repatriated.

Risks Related to Our Indebtedness and Capital Structure

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.

In 2020, we incurred significant additional indebtedness to finance the acquisition of Anixter, which increased our interest 
expense  from  historical  levels.  As  a  result,  a  substantial  portion  of  our  cash  flow  from  operations  must  be  dedicated  to  the 
payment  of  principal  and  interest  on  our  indebtedness,  thereby  reducing  the  funds  available  to  us  for  other  purposes.  As  of 
December 31, 2020, excluding debt discount and debt issuance costs, we had $5.0 billion of consolidated indebtedness. We and 
our  subsidiaries  may  also  undertake  additional  borrowings  in  the  future,  subject  to  certain  limitations  contained  in  the  debt 
instruments governing our indebtedness.

Over the next three years, we will be required to repay or refinance approximately $1.6 billion of our currently outstanding 

indebtedness.

Our debt service obligations impact our ability to operate and grow our business. Our payments of principal and interest on 
our indebtedness reduce the amount of funds available to us to invest in operations, future business opportunities, acquisitions, 
and other potentially beneficial activities. Our debt service obligations also reduce our flexibility to adjust to changing market 
conditions  and  may  increase  our  vulnerability  to  adverse  economic,  financial  market  and  industry  conditions.  Our  ability  to 
service  and  refinance  our  indebtedness,  make  scheduled  payments  on  our  operating  leases  and  fund  capital  expenditures, 
acquisitions  or  other  business  opportunities,  will  depend  in  large  part  on  both  our  future  performance  and  the  availability  of 
additional  financing  in  the  future,  as  well  as  prevailing  market  conditions  and  other  factors  beyond  our  control.  We  cannot 
assure you that it will be able to obtain additional financing on terms acceptable to us or at all.

Table of Contents

There can be no assurance that our business will continue to generate sufficient cash flows from operations in the future to 
service our debt, make necessary capital expenditures, or meet other cash needs. If we do not achieve the expected benefits and 
cost  savings  from  the  merger  with  Anixter,  or  if  the  financial  performance  of  the  combined  company  does  not  meet  current 
expectations, then our ability to service or repay our indebtedness may be adversely impacted. If unable to do so, we may be 
required to refinance all or a portion of our existing debt, sell assets, or obtain additional financing. We cannot make assurances 
that we will be able to refinance our debt on terms acceptable to us, or at all. If we are unable to repay indebtedness, lenders 
having secured obligations could proceed against the collateral securing these obligations.

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

Our  credit  facilities  and  our  other  debt  agreements,  including  those  governing  the  debt  financings  incurred  in  connection 

with the recent merger, contain various covenants  that restrict or limit our ability to,  among other things:

incur additional indebtedness or create liens on assets 
engage in mergers, acquisitions or consolidations,

•
•
• make loans or other investments, 
•
•

transfer, lease or dispose of assets outside the ordinary course of business, 
pay dividends, repurchase equity interests, make other payments with respect to equity interests, repay or repurchase 
subordinated debt, and
engage in affiliate transactions.

•

In  addition,  certain  of  these  debt  agreements  contain  financial  covenant  that  may  require  us  to  maintain  certain  financial 
ratios  and  other  requirements  in  certain  circumstances.  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 or taking advantage of new business opportunities that might otherwise be beneficial to 
us. Our ability to comply with these covenants and restrictions may be affected by economic, financial and industry conditions 
or  regulatory  changes  beyond  our  control.  Failure  to  comply  with  these  covenants  or  restrictions  could  result  in  an  event  of 
default, under our revolving lines of credit or the indentures governing certain of our outstanding notes which, if not cured or 
waived,  could  accelerate  our  repayment  obligations.  See  the  liquidity  section  in  "Item  7.  Management's  Discussion  and 
Analysis" for further details.

General Risk Factors

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

The global legal and regulatory environment is complex and 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, 
data privacy laws and regulations (and other laws applicable to publicly-traded companies such as the Foreign Corrupt Practices 
Act),  and  environmental  laws  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 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, and general commercial and securities matters. While we believe 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 these as well as other contingencies could require us to take actions, which could adversely affect our 
operations or could require us to pay substantial amounts of money.

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

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  operating  results.  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.

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. 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 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

We operate a network of nearly 700 branches and warehouse locations that hold inventory, and over 100 sales offices, with 
operations in more than 50 countries throughout the world. This includes 42 facilities with square footage between 100,000 and 
500,000 that operate as regional distribution centers or large branch locations, of which 33 are located in the U.S., six are in 
Canada, two are in Europe and one is in Latin America. Approximately 8% of our facilities are owned, and the remainder are 
leased.

We  also  lease  our  118,000  square-foot  headquarters  in  Pittsburgh,  Pennsylvania.  We  do  not  regard  the  real  property 
associated with any single facility as material to our operations. We believe our facilities are in good operating condition and 
are adequate for their respective uses.

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 litigation relating to commercial, product 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.

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

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  provider  of  business-to-business 
distribution, logistics services and supply chain solutions.

On June 22, 2020, WESCO completed its previously announced acquisition of Anixter, a Delaware corporation. Pursuant to 
the  terms  of  the  Agreement  and  Plan  of  Merger,  dated  January  10,  2020  (the  “Merger  Agreement”),  by  and  among  Anixter, 
WESCO and Merger Sub, Merger Sub was merged with and into Anixter (the “Merger”), with Anixter surviving the Merger 
and continuing as a wholly owned subsidiary of WESCO. On June 23, 2020, Anixter merged with and into Anixter Inc., with 
Anixter Inc. surviving to become a wholly owned subsidiary of WESCO.

As  a  result  of  the  Merger,  the  Company  now  employs  nearly  18,000  people,  maintains  relationships  with  approximately 
30,000 suppliers, and serves more than 125,000 customers worldwide. With nearly 1,500,000 products, end-to-end supply chain 
services,  and  extensive  digital  capabilities,  WESCO  provides  innovative  solutions  to  meet  current  customer  needs  across 
commercial  and  industrial  businesses,  contractors,  government  agencies,  institutions,  telecommunications  providers,  and 
utilities.  WESCO  has  approximately  800  branches,  warehouses  and  sales  offices  with  operations  in  more  than  50  countries, 
providing  a  local  presence  for  customers  and  a  global  network  to  serve  multi-location  businesses  and  multi-national 
corporations.

Prior to the completion of its merger with Anixter on June 22, 2020, as described in Note 6, "Acquisitions" of our Notes to 
Consolidated Financial Statements, WESCO had four operating segments that had been aggregated as one reportable segment. 
Effective on the date of acquisition, the Company added Anixter as a separate reportable segment for the quarterly period ended 
June 30, 2020. At the beginning of the third quarter of 2020, the Company identified new operating segments organized around 
three  strategic  business  units  consisting  of  Electrical  &  Electronic  Solutions  ("EES"),  Communications  &  Security  Solutions 
("CSS")  and  Utility  and  Broadband  Solutions  ("UBS").  The  applicable  comparative  financial  information  reported  in  the 
Company's  previously  issued  consolidated  financial  statements  for  the  years  ended  December  31,  2019  and  2018  have  been 
recast in this Annual Report on Form 10-K to conform to the basis of the new segments.

The following is a description of each of the Company's reportable segments and their business activities.

Overall Financial Performance

Our 2020 financial results reflect the half year impact of the merger with Anixter, partially offset by unfavorable business 
conditions caused by the COVID-19 pandemic. Net sales increased $4.0 billion, or 47.5%, over the prior year. Cost of goods 
sold as a percentage of net sales and gross profit margin was 81.1% and 18.9%, respectively, for both 2020 and 2019. Cost of 
goods sold for 2020 includes merger-related fair value adjustments of $43.7 million, as well as an out-of-period adjustment of 
$18.9 million related to inventory absorption accounting. Adjusted for these amounts, gross profit as a percentage of net sales 
for  2020  was  19.4%.  Selling,  general  and  administrative  ("SG&A")  expenses  as  a  percentage  of  net  sales  were  15.1%  and 
14.0% for 2020 and 2019, respectively. SG&A expenses for 2020 include merger-related costs of $132.2 million, as well as a 
gain on the sale of a U.S. operating branch of $19.8 million. Adjusted for these amounts, SG&A expenses for 2020 were $1.7 
billion, or 14.2% of net sales, reflecting lower sales and the merger with Anixter, partially offset by cost reduction actions taken 
in  response  to  the  COVID-19  pandemic.  SG&A  expenses  for  2019  include  $3.1  million  of  merger-related  costs.  Operating 
income  was  $347.0  million  for  2020,  compared  to  $346.2  million  for  2019.  Operating  income  for  2020  includes  the 
aforementioned merger-related costs, merger-related fair value adjustments, out-of-period adjustment, and gain on the sale of a 
U.S. operating branch. Adjusted for these items, operating profit was $522.0 million, or 4.2% of net sales. For 2019, operating 
profit  adjusted  for  merger-related  costs  of  $3.1  million  was  $349.3  million,  or  4.2%  of  net  sales.  Net  income  attributable  to 
common  stockholders  for  2020  and  2019  was  $70.4  million  and  $223.4  million,  respectively.  As  adjusted  for  the 
aforementioned  items,  including  the  related  income  tax  effects,  net  income  attributable  to  common  stockholders  was  $203.6 
million and $225.9 million for 2020 and 2019, respectively. Earnings per diluted share attributable to common stockholders was 
$1.51 in 2020, based on 46.6 million diluted shares, compared with earnings per diluted share of $5.14 in 2019, based on 43.5 
million diluted shares. As adjusted, earnings per diluted share for 2020 and 2019 was $4.37 and $5.20, respectively.

During  2020,  the  COVID-19  pandemic  had  a  significant  impact  on  our  business  and  adversely  impacted  our  results  of 
operations. We expect these negative impacts to continue during the first quarter of 2021, and potentially longer, depending on 
the  duration  and  severity  of  the  pandemic,  any  resurgence  of  COVID-19,  the  development  and  availability  of  effective 
treatments and vaccines, and other future developments that are currently uncertain and cannot be predicted.

Events and factors relating to the COVID-19 pandemic include limitations on the ability of our suppliers to manufacture or 
procure  the  products  we  sell  or  to  meet  delivery  requirements  and  commitments;  disruptions  to  our  global  supply  chains; 
limitations on the ability of our employees to perform their work due to travel or other restrictions; limitations on the ability of 
carriers  to  deliver  our  products  to  our  customers;  limitations  on  the  ability  of  our  customers  to  conduct  their  business  and 
purchase  our  products  and  services,  or  pay  us  on  a  timely  basis;  and  disruptions  to  our  customers’  purchasing  patterns.  In 
response  to  the  COVID-19  pandemic,  we  have  taken  actions  focused  on  protecting  the  health  and  safety  of  our  employees, 
which is our top priority. We have restricted non-essential business travel, implemented remote work protocols, and instituted 
preventive measures at our facilities, including enhanced health and safety protocols, temperature screening and requiring face 
coverings for employees.

The  products  and  services  that  we  provide  are  integral  to  the  daily  operations  of  our  essential  business  customers  and 
accordingly,  we  have  taken  actions  to  maintain  the  continuity  of  our  operations  in  response  to  the  pandemic.  To  date,  our 
branch locations have remained operational consistent with governmental and public health authority directives. Beginning in 
March 2020, and continuing throughout 2020, we have taken, and continue to take, actions to reduce costs consistent with the 
expected decline in demand, including reductions in administrative expenses, payroll and benefits, and other spending across 
the  company.  Given  the  ongoing  uncertainty  regarding  the  duration,  severity  and  scope  of  the  COVID-19  pandemic,  we  are 
continuing to monitor the situation and may take further actions in light of future developments.

We have experienced, and may continue to experience, reduced customer demand for certain of our products and services, 
including  delays  or  cancellations  of  ongoing  or  anticipated  projects  due  to  our  clients’,  suppliers’  and  other  third  parties’ 
diminished financial conditions. We cannot predict the timeframe for recovery of our customer’s demand for our products and 
services.  The  full  extent  to  which  the  COVID-19  pandemic  will  continue  to  impact  our  business  and  financial  results  going 
forward  is  highly  uncertain  and  will  depend  on  many  factors  outside  of  our  control,  including  the  duration  and  scope  of  the 
crisis, the development and availability of effective treatments and vaccines, imposition of protective public safety measures,  
and the overall impact of the COVID-19 pandemic on the global economy and capital markets.

Certain  triggering  events  occurred  during  the  first  quarter  of  2020,  including  the  effect  of  the  ongoing  macroeconomic 
disruption  and  uncertainty  caused  by  the  COVID-19  pandemic,  as  well  as  the  decline  in  our  share  price  and  market 
capitalization,  both  of  which  indicated  that  the  carrying  value  of  goodwill  and  indefinite-lived  intangible  assets  may  not  be 
recoverable. Accordingly, we performed an interim test for impairment as of March 31, 2020. There were no impairment losses 
identified as a result of this interim test.

Table of Contents

As  disclosed  in  Note  2,  "Accounting  Policies"  of  our  Notes  to  Consolidated  Financial  Statements,  we  identified  new 
operating segments during the third quarter of 2020, which changed the composition of our reporting units. Accordingly, we 
reassigned  goodwill  to  the  new  reporting  units  using  a  relative  fair  value  allocation  approach.  We  performed  a  goodwill 
impairment test immediately before and after we reorganized our reporting structure. Goodwill was tested for impairment on a 
reporting unit level and the evaluation involved comparing the fair value of each reporting unit to its carrying value. The fair 
values of our reporting units were determined using a discounted cash flow analysis, and consideration was also given to market 
multiples.  In  performing  the  quantitative  assessments,  management  used  expected  operating  margins  supported  by  a 
combination of historical results, current forecasts, market data and recent economic events, which are categorized within Level 
3 of the fair value hierarchy. We used a discount rate that reflects market participants' cost of capital. There were no impairment 
losses identified as a result of these tests. Although our reorganized reporting units had fair values that exceeded the respective 
carrying values, the EES reporting unit had an estimated fair value that exceeded its respective carrying value by less than 10%. 
As a result, the EES reporting unit is more susceptible to impairment risk from adverse macroeconomic conditions and if such 
conditions were to persist the underlying cash flows used to estimate fair value may impact the recoverability of goodwill.

We  performed  our  annual  impairment  tests  of  goodwill  and  indefinite-lived  intangible  assets  during  the  fourth  quarter  of 
2020 by assessing qualitative factors to determine whether it was more likely than not that the fair value of a reporting unit was 
less  than  its  carrying  amount.  In  performing  this  qualitative  assessment,  we  assessed  relevant  events  and  circumstances, 
including  macroeconomic  conditions,  industry  and  market  considerations,  cost  factors,  overall  financial  performance,  other 
relevant events such as changes in key personnel, changes in the composition or carrying amount of the net assets of a reporting 
unit, and sustained decreases in share price. As a result of this assessment, we determined that the fair values of our reporting 
units continued to exceed the respective carrying amounts and, therefore, a quantitative impairment test was unnecessary.

The determination of fair value of the reporting units involves significant management judgment, particularly as it relates to 
the underlying assumptions and factors around expected operating margins and discount rate. Due to the ongoing uncertainty 
surrounding the current macroeconomic environment and conditions in the markets in which we operate, as well as the risk that 
we may not fully realize cost savings, operating synergies or revenue improvement as a result of its acquisition of Anixter, there 
can be no assurance that the fair values of our reporting units will exceed their carrying values in the future, and that goodwill 
and indefinite-lived intangible assets will be fully recoverable.

Cash Flow

We generated $543.9 million in operating cash flow during 2020. Cash provided by operating activities included net income 
of $100.0 million, adjustments to net income totaling $113.7 million, and changes in assets and liabilities of $330.2 million. 
Investing  activities  included  $3,707.6  million  to  fund  a  portion  of  the  merger  with  Anixter,  as  described  in  Note  6, 
"Acquisitions"  of  our  Notes  to  Consolidated  Financial  Statements,  and    $56.7  million  of  capital  expenditures.  Financing 
activities were comprised of $2,815.0 million of net proceeds from the issuance of senior unsecured notes to finance a portion 
of the merger with Anixter, borrowings and repayments of $1.2 billion and $948.0 million, respectively, related to our prior and 
new revolving credit facilities, as well as borrowings and repayments of $1.1 billion and $565.0 million, respectively, related to 
our  prior  and  amended  accounts  receivable  securitization  facility.  Financing  activities  for  2020  also  included  net  repayments 
related to our various international lines of credit of $9.7 million, $80.2 million of debt issuance costs associated with financing 
the merger with Anixter, and $30.1 million of dividends paid to holders of our Series A Preferred Stock.

Free cash flow for the years ended December 31, 2020 and 2019 was $586.1 million and $180.3 million, respectively.The following table sets forth the components of free cash flow:Twelve Months Ended December 31, 20202019(In millions)Cash flow provided by operations$ 543.9 $ 224.4 Less: Capital expenditures (56.7)  (44.1) Add: Merger-related expenditures 98.9  — Free cash flow$ 586.1 $ 180.3 Note: The table above reconciles cash flow provided by operations to free cash flow. Free cash flow is a non-GAAP financial measure of liquidity. Capital expenditures are deducted from operating cash flow to determine free cash flow. Free cash flow is available to fund investing and financing activities. For the twelve months ended December 31, 2020, the Company paid certain fees, expenses and other costs to consummate the merger with Anixter. Such expenditures have been added back to cash flow provided by operations to determine free cash flow for such period.Financing AvailabilityOn June 22, 2020, in connection with the Merger, we entered into a $1,100 million revolving credit facility (the “Revolving Credit Facility”), as a replacement of our existing revolving credit facility entered into on September 26, 2019. Also concurrent with the completion of the Merger, we amended our accounts receivable securitization facility (the “Receivables Facility”). On December 14, 2020, we amended the Revolving Credit Facility and Receivables Facility to permit an increase of the borrowing capacities under such facilities from $1,100 million to $1,200 million, and from $1,025 million to $1,200 million, respectively. Borrowings under the amended revolving credit and accounts receivable securitization facilities will be used to redeem our $500 million aggregate principal amount of 5.375% Senior Notes due 2021, as described in Note 19, "Subsequent Events" of the Notes to Consolidated Financial Statements.As of December 31, 2020, we had $801.5 million in total available borrowing capacity under our Revolving Credit Facility, which was comprised of $684.3 million of availability under the U.S. sub-facility and $117.3 million of availability under the Canadian sub-facility. Available borrowing capacity under our Receivables Facility was $75.0 million. The Revolving Credit Facility and the Receivables Facility mature in June 2025 and June 2023, respectively.Critical Accounting Policies and EstimatesOur 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 (U.S. 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 rebate income, expected credit losses, inventories, insurance costs, goodwill and indefinite-lived intangible assets, 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 RecognitionOur revenue arrangements generally consist of single performance obligations to transfer a promised good or service, or a combination of goods and services. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Revenue is recognized when control has transferred to the customer, which is generally when the product has shipped from our facility or directly from a supplier. However, transfer may occur at a later date depending on the agreed upon terms, such as delivery at the customer's designated location, or based on consignment terms. For products that ship directly from suppliers to customers, we act as the principal in the transaction and recognize revenue on a gross basis. When providing services, sales are recognized over time as control transfers to the customer, which occurs as services are rendered. We generally satisfy our performance obligations within a year or less.Table of Contents22Table of Contents

We generally do not have significant financing terms associated with our contracts; payments are normally received within 
60  days.  There  are  generally  no  significant  costs  associated  with  obtaining  customer  contracts.  We  typically  pass  through 
warranties offered by manufacturers or suppliers to our customers. Sales taxes (and value added taxes in foreign jurisdictions) 
collected from customers and remitted to governmental authorities are excluded from net sales.

Supplier Volume Rebates

We receive 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 
us based on forecasted purchases and the rebate provisions of the various supplier contracts. The corresponding volume rebate 
income is recorded as a reduction to cost of goods sold.

Allowance for Expected Credit Losses

We  recognize  expected  credit  losses  resulting  from  the  inability  of  our  customers  to  make  required  payments  through  an 
allowance account that is measured each reporting date. We estimate credit losses over the life of our trade accounts receivable 
using  a  combination  of  historical  loss  data,  current  credit  conditions,  specific  customer  circumstances,  and  reasonable  and 
supportable forecasts of future economic conditions.

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. We reduce the carrying value of our inventories at the earlier of 
identifying an item that is considered to be obsolete or in excess of supply relative to demand, or no movement in the past 15 
months.

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. We first assess qualitative factors, including 
macroeconomic  conditions,  industry  and  market  considerations,  cost  factors,  overall  financial  performance,  other  relevant 
events such as changes in key personnel, changes in the composition or carrying amount of the net assets of a reporting unit, 
and sustained decreases in share price, to determine whether it is more likely than not that the fair value of our reporting units 
are  less  than  their  carrying  values.  If  the  qualitative  assessment  indicates  that  the  fair  values  of  our  reporting  units  may  not 
exceed their respective carrying values, then we perform a quantitative test for impairment by comparing the fair value of each 
reporting unit to its carrying value. We determine the fair values of our reporting units using a discounted cash flow analysis 
and  consideration  of  market  multiples.  The  discounted  cash  flow  analysis  uses  certain  assumptions,  including  expected 
operating margins supported by a combination of historical results, current forecasts, market data and recent economic events, 
which are categorized within Level 3 of the fair value hierarchy. We use a discount rate that reflects market participants' cost of 
capital.  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,  particularly  as  it  relates  to  the  underlying 
assumptions  and  factors  around  expected  operating  margins  and  discount  rate.  Management  applies  its  best  judgment  when 
assessing the reasonableness of financial projections. Fair values 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.

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.

23

We recognize 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 taxable 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.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 the estimate recognized in the consolidated financial statements. We recognize interest and penalties related to uncertain tax benefits as part of interest expense and income tax expense, respectively.The Tax Cuts and Jobs Act of 2017 (the “TCJA”) imposed a one-time tax on the deemed repatriation of undistributed foreign earnings (the “transition tax”). Except for a portion of foreign earnings previously taxed in the U.S. that can effectively be distributed without further material U.S. or foreign taxation, we continue to assert that the undistributed earnings of our foreign subsidiaries are indefinitely reinvested. To the extent the earnings of our foreign subsidiaries are distributed in the form of dividends, such earnings may be subject to additional taxes. We believe that we are able to maintain a sufficient level of liquidity for our domestic operations and commitments without incurring any material tax cost to repatriate cash held by our foreign subsidiaries.The provisions of the TCJA also introduced U.S. taxation on certain global intangible low-taxed income ("GILTI"). We have elected to account for GILTI tax as a component of income tax expense.Results of OperationsThe following table sets forth the percentage relationship to net sales of certain items in our Consolidated Statements of Income and Comprehensive Income for the periods presented:Year Ended December 31,202020192018Net sales 100.0 % 100.0 % 100.0 %Cost of goods sold (excluding depreciation and amortization) 81.1  81.1  80.8 Selling, general and administrative expenses 15.1  14.0  14.1 Depreciation and amortization 1.0  0.8  0.8 Income from operations 2.8  4.1  4.3 Interest expense, net 1.8  0.8  0.8 Other, net —  (0.1)  0.1 Income before income taxes 1.0  3.4  3.4 Provision for income taxes 0.2  0.7  0.6 Net income attributable to WESCO International, Inc. 0.8  2.7  2.8 Preferred stock dividends 0.2  —  — Net income attributable to common stockholders 0.6 % 2.7 % 2.8 %Table of Contents242020 Compared to 2019Net SalesThe following table sets forth net sales by segment for the periods presented:Year Ended December 31,(In thousands)20202019Growth (Decline)EES$ 5,479,760 $ 4,860,541  12.7 %CSS 3,323,264  909,496  265.4 %UBS 3,522,971  2,588,880  36.1 %Total net sales$ 12,325,995 $ 8,358,917  47.5 %Net sales were $12.3 billion in 2020 compared with $8.4 billion in 2019, an increase of 47.5% due to the merger with Anixter that was completed on June 22, 2020, partially offset by the impact of weakened demand from the COVID-19 pandemic.EES reported net sales of $5.5 billion in 2020, compared to $4.9 billion in 2019, an increase of 12.7%. The increase reflects the impact of the merger with Anixter, partially offset by weakened global demand in construction and industrial markets due to local and government shutdowns associated with the COVID-19 pandemic, as well as related disruptions to our suppliers and customers that have caused delays to projects.CSS reported net sales of $3.3 billion in 2020, compared to $0.9 billion in 2019, an increase of 265.4%. The increase reflects the impact of the merger with Anixter. The COVID-19 pandemic had an overall negative impact on CSS sales, although some customers and end users are considered essential businesses that saw increased demand.UBS reported net sales of $3.5 billion in 2020, compared to $2.6 billion in 2019, an increase of 36.1%. The increase reflects the impact of the merger with Anixter. The COVID-19 pandemic had a limited impact on UBS sales as the primary customers in this segment are public power and investor owned utilities, which are considered essential business and have maintained normal operations.Cost of Goods SoldCost of goods sold for 2020 was $10.0 billion, compared to $6.8 billion for 2019. Cost of goods sold as a percentage of net sales was 81.1% in both 2020 and 2019. Cost of goods sold for 2020 includes merger-related fair value adjustments of $43.7 million, as well as an out-of-period adjustment of $18.9 million related to inventory absorption accounting. Adjusted for these amounts, cost of goods sold as a percentage of net sales for 2020 was 80.6%.Selling, General and Administrative ExpensesSG&A expenses include costs associated with personnel, shipping and handling, travel, advertising, facilities, utilities and credit losses. SG&A expenses for 2020 were $1.9 billion, an increase of $685.9 million, or 58.5%, from 2019. SG&A expenses as a percentage of net sales increased to 15.1% in 2020 from 14.0% in 2019. SG&A expenses for 2020 include merger-related costs of $132.2 million, as well as a gain on the sale of a U.S. operating branch of $19.8 million. Adjusted for these amounts, SG&A expenses for 2020 were $1.7 billion, or 14.2% of net sales, reflecting the merger with Anixter and lower sales, partially offset by cost reduction actions taken in response to the COVID-19 pandemic. SG&A expenses for 2019 include $3.1 million of merger-related costs.SG&A payroll expenses for 2020 of $1.2 billion increased by $398.1 million compared to 2019 primarily due to the merger with Anixter. Excluding the impact of the merger, SG&A payroll expenses were down $35.0 million due to lower salaries and wages, variable compensation expense and benefit costs resulting from cost reduction actions associated with the COVID-19 pandemic.The remaining SG&A expenses for 2020 of $648.0 million increased by $287.8 million compared to 2019. The increase in the remaining SG&A expenses was primarily due to the impact of the merger with Anixter.Table of Contents25Depreciation and AmortizationDepreciation and amortization increased $59.5 million to $121.6 million in 2020, compared with $62.1 million in 2019. The current period includes $33.0 million of amortization attributable to identifiable intangible assets acquired in the merger with Anixter.Income from OperationsThe following tables set forth income from operations by segment for the periods presented:Year Ended December 31, 2020(In thousands)EESCSSUBSCorporateTotalIncome from operations$ 260,207 $ 217,163 $ 231,702 $ (362,034) $ 347,038 Year Ended December 31, 2019(In thousands)EESCSSUBSCorporateTotalIncome from operations$ 261,788 $ 43,835 $ 184,931 $ (144,337) $ 346,217 EES reported operating profit of $260.2 million in 2020, compared to $261.8 million in 2019.

The increase reflects the impact of the merger with Anixter. The benefits of cost reduction actions taken in response to the COVID-19 pandemic, as well as operating synergies resulting from the business combination, had a favorable impact on operating profit.UBS reported operating profit of $231.7 million in 2020, compared to $184.9 million in 2019. The increase reflects the impact of the merger with Anixter. The impact of the COVID-19 pandemic on the UBS segment was limited as many of its primary customers are public power and investor owned utilities that are considered essential businesses and have maintained normal operations.Interest Expense, netInterest expense, net totaled $226.6 million in 2020, compared with $65.7 million in 2019, an increase of 244.8%. The increase in interest expense was driven by financing activity related to the Anixter merger.Other, netOther non-operating income ("other, net") totaled $2.4 million in 2020, compared to $1.6 million in 2019.Income TaxesOur effective tax rate was 18.6% in 2020 compared to 21.2% in 2019. The lower effective tax rate in the current year was primarily due to one-time impacts from the merger with Anixter.Net Income and Earnings per ShareNet income for 2020 was $100.0 million, compared to $222.2 million for 2019.Net loss attributable to noncontrolling interests in 2020 and 2019 was $0.5 million and $1.2 million, respectively.Preferred stock dividends expense of $30.1 million in 2020 relates to the fixed-rate reset cumulative perpetual preferred stock, Series A, that was issued in connection with the merger.Net income and earnings per diluted share attributable to common stockholders were $70.4 million and $1.51 per diluted share, respectively, in 2020, compared with $223.4 million and $5.14 per diluted share, respectively, in 2019. Adjusted for the items mentioned above, net income and earnings per diluted share attributable to common stockholders were $203.6 million and $4.37 per diluted share, respectively, for the year ended December 31, 2020.

EBITDA is defined as earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA before other non-operating expenses ("other, net"), non-cash stock-based compensation, merger-related costs and fair value adjustments, an out-of-period adjustment related to inventory absorption accounting, and gain on sale of a U.S. operating branch. Adjusted EBITDA margin % is calculated by dividing Adjusted EBITDA by net sales.Adjusted EBITDA for EES was $294.9 million in 2020, or 5.4% of net sales, compared to $291.5 million in 2019, or 6.0% of net sales.Adjusted EBITDA for CSS was $289.6 million in 2020, or 8.7% of net sales, compared to $51.1 million in 2019, or 5.6% of net sales.Adjusted EBITDA for UBS was $264.6 million in 2020, or 7.5% of net sales, compared to $198.7 million in 2019, or 7.7% of net sales.Table of Contents282019 Compared to 2018Net SalesThe following table sets forth net sales by segment for the periods presented:Year Ended December 31,(In thousands)20192018Growth (Decline)EES$ 4,860,541 $ 4,878,836  (0.4) %CSS 909,496  857,481  6.1 %UBS 2,588,880  2,440,284  6.1 %Total net sales$ 8,358,917 $ 8,176,601  2.2 %Net sales were $8.4 billion in 2019 compared with $8.2 billion in 2018, an increase of 2.2%.EES reported net sales of $4.9 billion in both 2019 and 2018. The moderate decline of 0.4% reflects skilled labor constraints and overall uncertainty related to the macroeconomic environment and international trade concerns.CSS reported net sales of $909.5 million in 2019, compared to $857.5 million in 2018. The increase of 6.1% reflects growth in the data communications and security categories.UBS reported net sales of $2.6 billion in 2019, compared to $2.4 billion in 2018. The increase of 6.1% reflects the benefit of secular trends in the utility sector, including grid hardening and reliability projects, construction market growth, higher industrial output and increased demand for renewable energy.Cost of Goods SoldCost of goods sold for 2019 was $6.8 billion, compared to $6.6 billion for 2018. Cost of goods sold as a percentage of net sales was 81.1% and 80.8% in 2019 and 2018, respectively. Cost of goods sold as a percentage of net sales was negatively impacted by a challenging pricing environment, as well as business mix.Selling, General and Administrative ExpensesSG&A expenses include costs associated with personnel, shipping and handling, travel, advertising, facilities, utilities and credit losses. SG&A expenses for 2019 were $1.2 billion, an increase of $21.2 million, or 1.8%, from 2018. SG&A expenses as a percentage of net sales improved to 14.0% in 2019 from 14.1% in 2018. The increase in SG&A expenses reflects the impact of the SLS acquisition and merger-related costs, partially offset by lower variable payroll expenses and the absence of a bad debt charge that was recorded in the prior year.SG&A payroll expenses for 2019 of $812.9 million increased by $8.7 million compared to 2018. The increase in SG&A payroll expenses was primarily due to wage inflation and the impact of the SLS acquisition, which were partially offset by lower variable compensation expense and benefit costs.The remaining SG&A expenses for 2019 of $360.2 million increased by $12.4 million compared to 2018. The increase in the remaining SG&A expenses was primarily due to the impact of the SLS acquisition.Depreciation and AmortizationDepreciation and amortization decreased $0.9 million to $62.1 million in 2019, compared with $63.0 million in 2018.Table of Contents29Income from OperationsThe following tables set forth income from operations by segment for the periods presented:Year Ended December 31, 2019(In thousands)EESCSSUBSCorporateTotalIncome from operations$ 261,788 $ 43,835 $ 184,931 $ (144,337) $ 346,217 Year Ended December 31, 2018(In thousands)EESCSSUBSCorporateTotalIncome from operations$ 289,065 $ 34,592 $ 165,149 $ (136,366) $ 352,440 EES reported operating profit of $261.8 million in 2019, compared to $289.1 million in 2018.

In  connection  with  the  Merger,  we  obtained  debt  financing  comprised  of  senior  unsecured  notes  in  aggregate  principal 

amount of $2.8 billion, a new senior secured asset-based revolving credit facility in aggregate principal amount of $1.1 billion, 

and an amended accounts receivable securitization facility with a purchase limit up to $1.0 billion. Prior to the completion of 

the Merger, we also simultaneously entered into tender offers and consent solicitations with respect to Anixter's 5.50% Senior 

Notes  due  2023  and  6.00%  Senior  Notes  due  2025  (collectively,  the  "Anixter  Senior  Notes").  Upon  the  expiration  and 

settlement  of  the  tender  offers  and  consent  solicitations,  $62.8  million  in  aggregate  principal  amount  of  the  Anixter  Senior 

Notes remain outstanding.

We  used  the  net  proceeds  from  the  issuance  of  senior  unsecured  notes,  together  with  borrowings  under  the  new  senior 

secured asset-based revolving credit facility and amended accounts receivable securitization facility, as well as existing cash on 

hand  to  consummate  the  merger.  Since  the  acquisition,  we  have  reduced  our  outstanding  indebtedness  by  approximately 

$205 million. Over the next several quarters, it is expected that excess liquidity will be directed primarily at debt reduction and 

merger-related  integration  activities,  and  we  expect  to  maintain  sufficient  liquidity  through  our  credit  facilities  and  cash 

balances. We expect to spend between $100 million to $120 million on capital expenditures in 2021, much of which will be 

invested to align the systems of our legacy businesses and enhance our digital tools.

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 5.3 as of December 31, 2020, on a pro forma basis, and 2.7 as of December 31, 2019, as reported. In addition, we are in

As of December 31, 2020, we had $801.5 million in available borrowing capacity under our Revolving Credit Facility and $75.0 million in available borrowing capacity under our Receivables Facility, which combined with available cash of $259.5 million, provided liquidity of $1.1 billion. Cash included in our determination of liquidity represents cash in certain deposit and interest bearing investment accounts. We believe cash provided by operations and financing activities will be adequate to cover our operational and business needs for at least the next twelve months. In addition, we regularly review our mix of fixed versus variable rate debt, and we may, from time to time, issue or retire borrowings and/or refinance existing debt in an effort to mitigate the impact of interest rate and foreign exchange rate fluctuations, and to maintain a cost-effective capital structure consistent with our anticipated capital requirements. At December 31, 2020, approximately 75% of our debt portfolio was comprised of fixed rate debt.Table of Contents33Table of Contents

In  connection  with  the  Merger,  we  obtained  debt  financing  comprised  of  senior  unsecured  notes  in  aggregate  principal 
amount of $2.8 billion, a new senior secured asset-based revolving credit facility in aggregate principal amount of $1.1 billion, 
and an amended accounts receivable securitization facility with a purchase limit up to $1.0 billion. Prior to the completion of 
the Merger, we also simultaneously entered into tender offers and consent solicitations with respect to Anixter's 5.50% Senior 
Notes  due  2023  and  6.00%  Senior  Notes  due  2025  (collectively,  the  "Anixter  Senior  Notes").  Upon  the  expiration  and 
settlement  of  the  tender  offers  and  consent  solicitations,  $62.8  million  in  aggregate  principal  amount  of  the  Anixter  Senior 
Notes remain outstanding.

We  used  the  net  proceeds  from  the  issuance  of  senior  unsecured  notes,  together  with  borrowings  under  the  new  senior 
secured asset-based revolving credit facility and amended accounts receivable securitization facility, as well as existing cash on 
hand  to  consummate  the  merger.  Since  the  acquisition,  we  have  reduced  our  outstanding  indebtedness  by  approximately 
$205 million. Over the next several quarters, it is expected that excess liquidity will be directed primarily at debt reduction and 
merger-related  integration  activities,  and  we  expect  to  maintain  sufficient  liquidity  through  our  credit  facilities  and  cash 
balances. We expect to spend between $100 million to $120 million on capital expenditures in 2021, much of which will be 
invested to align the systems of our legacy businesses and enhance our digital tools.

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 5.3 as of December 31, 2020, on a pro forma basis, and 2.7 as of December 31, 2019, as reported. In addition, we are in 
compliance with all covenants and restrictions contained in our debt agreements as of December 31, 2020.

Financial leverage ratio is calculated by dividing total debt, excluding debt discount, debt issuance costs and fair value adjustments, less cash and cash equivalents, by adjusted EBITDA. EBITDA is defined as the trailing twelve months earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA is defined as the trailing twelve months EBITDA before foreign exchange and other non-operating expenses, non-cash stock-based compensation, merger-related costs and fair value adjustments, an out-of-period adjustment related to inventory absorption accounting, and gain on sale of a U.S.operating branch. Pro forma financial leverage ratio is calculated by dividing total debt, excluding debt discount and debt issuance costs, less cash and cash equivalents, by pro forma adjusted EBITDA.Undistributed earnings of our foreign subsidiaries amounted to approximately $1,835.0 million at December 31, 2020. Most of these earnings have been taxed in the U.S. under either the one-time transition tax or the GILTI tax regime imposed by the TCJA. Except for a portion of foreign earnings previously taxed in the U.S. that can effectively be distributed without further material U.S. or foreign taxation, we continue to assert that the undistributed earnings of our foreign subsidiaries are indefinitely reinvested. To the extent the earnings of our foreign subsidiaries are distributed in the form of dividends, such earnings may be subject to additional taxes. We estimate that additional taxes of approximately $75.0 million would be payable upon the remittance of foreign earnings as dividends at December 31, 2020, based upon the laws in effect on that date. We Table of Contents35Table of Contents

believe  that  we  are  able  to  maintain  a  sufficient  level  of  liquidity  for  our  domestic  operations  and  commitments  without 
incurring any material tax cost to repatriate cash held by our foreign subsidiaries. 

We finance our operating and investing needs as follows:

International Lines of Credit

Certain  foreign  subsidiaries  of  WESCO  have  entered  into  uncommitted  lines  of  credit,  some  of  which  are  overdraft 
facilities,  to  support  local  operations.  The  maximum  borrowing  limit  varies  by  facility  and  ranges  between  $2.0  million  and 
$31.0 million. The international lines of credit generally are renewable on an annual basis and certain facilities are fully and 
unconditionally  guaranteed  by  WESCO  Distribution.  Accordingly,  certain  borrowings  under  these  lines  directly  reduce 
availability under the Revolving Credit Facility. The applicable interest rate for borrowings under these lines of credit varies by 
country and is governed by the applicable loan agreement. The average interest rate for these facilities was 3.4% and 6.3% at 
December 31, 2020 and 2019, respectively.

Accounts Receivable Securitization Facility

On June 22, 2020, WESCO Distribution amended its Receivables Facility pursuant to the terms and conditions of a Fifth 
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 amends and restates the 
amended and restated receivables purchase agreement entered into on September 24, 2015 (the “Existing Receivables Purchase 
Agreement”).

The  Receivables  Purchase  Agreement,  among  other  things,  increased  the  purchase  limit  under  the  Existing  Receivables 
Purchase Agreement from $600 million to $1,025 million, with the opportunity to exercise an accordion feature that permits 
increases in the purchase limit of up to $375 million, extended the term of the Receivables Facility to June 22, 2023 and added 
and amended certain defined terms. Borrowings under the Receivables Facility bear interest at the 30-day LIBOR rate, with a 
LIBOR  floor  of  0.5%,  plus  applicable  spreads.  The  interest  rate  spread  of  the  Receivables  Facility  increased  from  0.95%  to 
1.20%. The commitment fee remained unchanged at 0.45%.

On December 14, 2020, WESCO Distribution amended its Receivables Facility pursuant to the terms and conditions of a 
First Amendment to the Fifth Amended and Restated Receivables Purchase Agreement (the “Receivables Amendment”). The 
Receivables  Amendment  amends  the  Receivables  Purchase  Agreement  and  permits  an  increase  to  the  purchase  limit  from 
$1,025  million  to  $1,200  million.  The  maturity  date,  interest  rate  spread,  and  commitment  fee  of  the  Receivables  Facility 
remain unchanged.

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.  Since  WESCO  maintains  control  of  the  transferred  receivables,  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.  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,  2020  and  2019,  accounts  receivable  eligible  for  securitization  totaled  $1,476.1  million  and  $809.5 
million, respectively. The Consolidated Balance Sheets as of December 31, 2020 and 2019 include $950.0 million and $415.0 
million, respectively, of accounts receivable balances legally sold to third parties, as well as borrowings for equal amounts. At 
December 31, 2020, the interest rate for this facility was approximately 1.6%.

Revolving Credit Facility

On June 22, 2020, WESCO, WESCO Distribution and certain other subsidiaries of WESCO entered into a $1,100 million 
revolving credit facility (the “Revolving Credit Facility”), as a replacement of WESCO Distribution’s revolving credit facility 
entered into on September 26, 2019, pursuant to the terms and conditions of a Fourth Amended and Restated Credit Agreement, 
dated as of June 22, 2020 (the “Revolving Credit Agreement”), among WESCO Distribution, the other U.S. borrowers party 
thereto  (collectively,  the  “U.S.  Borrowers”),  WESCO  Distribution  Canada  LP  (“WESCO  Canada”),  the  other  Canadian 
borrowers party thereto (collectively, the “Canadian Borrowers”), WESCO, the lenders party thereto and Barclays Bank PLC, 
as the administrative agent. The Revolving Credit Facility contains a letter of credit sub-facility of up to $175 million and an 
accordion  feature  allowing  WESCO  Distribution  to  request  increases  to  the  borrowing  commitments  under  the  Revolving 
Credit Facility of up to $500 million in the aggregate, subject to customary conditions. The Revolving Credit Facility matures 
in June 2025.

On December 14, 2020, WESCO Distribution and certain other subsidiaries of WESCO entered into an amendment to the 
Revolving Credit Facility pursuant to the terms and conditions of a First Amendment to Fourth Amended and Restated Credit 
Agreement,  dated  as  of  December  14,  2020  (the  “Revolver  Amendment”),  among  WESCO  Distribution,  the  other  U.S. 
borrowers  party  thereto,  WESCO  Distribution  Canada  LP,  the  other  Canadian  borrowers  party  thereto,  WESCO,  the  lenders 
party thereto and Barclays Bank PLC, as administrative agent. The Revolver Amendment permits an increase to the revolving 
commitments  from  $1,100  million  to  $1,200  million  and  amends  certain  other  defined  terms.    No  other  material  terms  were 
changed.

The  obligations  of  WESCO  Distribution  and  the  other  U.S.  Borrowers  under  the  Revolving  Credit  Facility  have  been 
guaranteed  by  WESCO  and  certain  of  WESCO  Distribution’s  subsidiaries  (including  certain  subsidiaries  of  Anixter).  The 
obligations  of  WESCO  Canada  and  the  other  Canadian  Borrowers  under  the  Revolving  Credit  Facility  (including  certain 
subsidiaries of Anixter) have been guaranteed by certain subsidiaries of WESCO Canada and the other Canadian Borrowers. 
The Revolving Credit Facility is secured by (i) substantially all assets of WESCO Distribution, the other U.S. Borrowers and 
certain of WESCO Distribution’s subsidiaries (including certain subsidiaries of Anixter), other than, among other things, real 
property and accounts receivable sold or intended to be sold pursuant to WESCO Distribution’s Receivables Facility, and (ii) 
substantially all assets of WESCO Canada, the other Canadian Borrowers and certain of WESCO Canada’s subsidiaries, other 
than, among other things, real property, in each case, subject to customary exceptions and limitations. 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  1.50%  for  LIBOR-based  borrowings  and  0.25%  and  0.50%  for  prime  rate-based  borrowings.  At 
December 31, 2020, the interest rate for this facility was approximately 1.6%.

The Revolving Credit Agreement requires compliance with conditions that must be satisfied prior to any borrowing as well 
as ongoing compliance with certain customary affirmative and negative covenants. The Revolving Credit Agreement contains 
customary events of default. Upon the occurrence and during the continuance of an event of default, the commitments of the 
lenders  may  be  terminated,  and  all  outstanding  obligations  of  the  loan  parties  under  the  Revolving  Credit  Facility  may  be 
declared immediately due and payable.

During 2020, WESCO borrowed $1,197.9 million under the prior and new revolving credit facilities and made repayments 
in  the  aggregate  amount  of  $948.0  million.  During  2019,  aggregate  borrowings  and  repayments  under  prior  revolving  credit 
agreements were $715.4 million and $767.4 million, respectively. WESCO had $801.5 million available under the Revolving 
Credit facility at December 31, 2020, after giving effect to $48.5 million of outstanding letters of credit, as compared to $563.8 
million  available  under  the  prior  revolving  credit  facility  at  December  31,  2019,  after  giving  effect  to  $28.4  million  of 
outstanding letters of credit, $36.1 million of surety bonds, and $7.8 million of other reserves.

5.375% Senior Notes due 2021

In November 2013, WESCO Distribution issued $500 million aggregate principal amount of 5.375% Senior Notes due 2021 
(the  "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 between 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% per annum, 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 and at any time all or a part may be redeemed by WESCO Distribution. 
The net proceeds of the 2021 Notes were used to prepay a portion of the U.S. sub-facility of the term loan 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.

On  December  15,  2020,  WESCO  Distribution  exercised  its  right  to  redeem  the  entire  $500  million  aggregate  principal 
amount  of  the  2021  Notes,  and  U.S.  Bank,  National  Association,  as  trustee  under  the  indenture  governing  the  2021  Notes, 
issued a notice of redemption to registered holders of the 2021 Notes. The date fixed for the redemption of the 2021 Notes is 
January  14,  2021  (the  “Redemption  Date”).  The  2021  Notes  will  be  redeemed  at  a  redemption  price  equal  to  100%  of  the 
principal amount of the 2021 Notes plus accrued interest on the 2021 Notes to, but not including, the Redemption Date.

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 stated rate of 5.375% per annum, payable semi-annually in arrears on June 15 
and December 15 of each year. 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  notes.  The  2024  Notes  mature  on 
June 15, 2024. The Company used the net proceeds to redeem its 6.0% Convertible Senior Debentures due 2029 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. 

Any time 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. 

5.50% Senior Notes due 2023
6.00% Senior Notes due 2025

On April 30, 2020, in connection with the Merger, WESCO Distribution commenced offers to purchase for cash (each, a 
“WESCO Tender Offer” and, together the “WESCO Tender Offers”) any and all of Anixter Inc.’s outstanding (i) 5.50% Senior 
Notes  due  2023  (the  “Anixter  2023  Senior  Notes”),  $350.0  million  aggregate  principal  amount,  issued  under  the  Indenture, 
dated  as  of  August  18,  2015  (the  “Anixter  2023  Indenture”),  by  and  among  Anixter  Inc.,  Anixter  and  Wells  Fargo  Bank, 
National Association, as trustee, and (ii) 6.00% Senior Notes due 2025 (the “Anixter 2025 Senior Notes” and, together with the 
Anixter 2023 Senior Notes, the "Anixter Senior Notes"), $250.0 million aggregate principal amount, issued under the Indenture, 
dated  as  of  November  13,  2018  (the  “Anixter  2025  Indenture”  and,  together  with  the  Anixter  2023  Indenture,  the  “Anixter 
Indentures”) by and among Anixter Inc., Anixter and Wells Fargo Bank, National Association, as trustee.

Concurrent  with  the  WESCO  Tender  Offers,  Anixter  Inc.  commenced  consent  solicitations  to  amend  the  definition  of 
"Change  of  Control"  under  the  applicable  Indenture  to  exclude  the  Merger  and  related  transactions  and  expressly  permit  a 
merger between Anixter Inc. and Anixter (the “Anixter Consent Solicitations”).

On June 23, 2020 (the "Expiration Date"), following the completion of the Merger, the WESCO Tender Offers and Anixter 
Consent Solicitations expired and settled. Pursuant to the terms of the Offer to Purchase and Consent Solicitation Statement, 
dated April 30, 2020, holders of the Anixter Senior Notes that validly tendered and did not validly withdraw prior to such date, 
received total tender offer consideration of $1,012.50 per $1,000 principal amount of Anixter Senior Notes, which amount, in 
each  case,  included  an  early  tender  payment  of  $50.00  per  $1,000  principal  amount  of  Anixter  Senior  Notes.  Holders  who 
validly delivered their consents at or prior to the Expiration Date received a consent fee of $2.50 per $1,000 principal amount of 
Anixter Senior Notes.

As of December 31, 2020, $58.6 million and $4.2 million aggregate principal amount of the Anixter 2023 Senior Notes and 

Anixter 2025 Senior Notes, respectively, were outstanding.

7.125% Senior Notes due 2025
7.250% Senior Notes due 2028

On  June  12,  2020,  WESCO  Distribution  issued  $1,500  million  aggregate  principal  amount  of  7.125%  Senior  Notes  due 
2025 (the “2025 Notes”) and $1,325 million aggregate principal amount of 7.250% Senior Notes due 2028 (the “2028 Notes” 
and, together with the 2025 Notes, the “Notes”). The 2025 Notes were issued at a price of 100.000% of the aggregate principal 
amount. The 2028 Notes were issued at a price of 99.244% of the aggregate principal amount. WESCO incurred costs related to 
the issuance of the 2025 Notes and 2028 Notes totaling $33.1 million and $29.3 million, respectively, which were recorded as a 
reduction to the carrying value of the debt and are being amortized over the respective lives of the notes.

The Notes were issued pursuant to, and are governed by, an indenture (the “Notes Indenture”), dated as of June 12, 2020, 
between  the  Company,  WESCO  Distribution  and  U.S.  Bank  National  Association,  as  trustee  (the  “Trustee”).  The  Notes  and 
related  guarantees  were  issued  in  a  private  transaction  exempt  from  the  Securities  Act  of  1933,  as  amended  (the  “Securities 
Act”) and have not been, and will not be, registered under the Securities Act and may not be offered or sold in the U.S. absent 
registration or an applicable exemption from, or in a transaction not subject to the registration requirements of the Securities 
Act and other applicable securities laws.

The Company used the net proceeds from the issuance of the Notes, together with borrowings under its new and amended 
credit  facilities  and  existing  cash  on  hand,  to  finance  the  Merger  and  the  other  transactions  contemplated  by  the  Merger 
Agreement. The use of proceeds included (i) paying the cash portion of the Merger consideration to stockholders of Anixter, (ii) 
refinancing  certain  existing  indebtedness  of  Anixter  contemplated  by  the  Merger  Agreement,  including  financing  the 
satisfaction and discharge, defeasance, redemption or other repayment in full of the 5.125% Senior Notes due 2021 of Anixter 
Inc., a wholly owned subsidiary of Anixter, and financing payments in connection with the Anixter Consent Solicitations and 
WESCO Tender Offers, as described above, (iii) refinancing other indebtedness of the Company, and (iv) paying fees, costs and 
expenses in connection with the foregoing.

The  Notes  are  unsecured  and  unsubordinated  obligations  of  WESCO  Distribution  and  are  guaranteed  on  an  unsecured, 
unsubordinated basis by the Company and Anixter Inc. The 2025 Notes accrue interest at a rate of 7.125% per annum, payable 
semi-annually in arrears on June 15 and December 15 of each year. The 2025 Notes will mature on June 15, 2025. The 2028 
Notes accrue interest at a rate of 7.250% per annum, payable semi-annually in arrears on June 15 and December 15 of each 
year. The 2028 Notes will mature on June 15, 2028.

WESCO Distribution may redeem all or a part of the 2025 Notes at any time prior to June 15, 2022 by paying a “make-
whole” premium plus accrued and unpaid interest, if any, to but excluding the redemption date. In addition, at any time prior to 
June 15, 2022, WESCO Distribution may redeem up to 35% of the 2025 Notes with the net cash proceeds from certain equity 
offerings. On or after June 15, 2022, WESCO Distribution may redeem all or a part of the 2025 Notes on the redemption dates 
and at the redemption prices specified in the Notes Indenture. WESCO Distribution may redeem all or a part of the 2028 Notes 
at any time prior to June 15, 2023 by paying a “make-whole” premium plus accrued and unpaid interest, if any, to but excluding 
the redemption date. In addition, at any time prior to June 15, 2023, WESCO Distribution may redeem up to 35% of the 2028 
Notes with the net cash proceeds from certain equity offerings. On or after June 15, 2023, WESCO Distribution may redeem all 
or a part of the 2028 Notes on the redemption dates and at the redemption prices specified in the Notes Indenture.

to  pay  dividends  on  or  repurchase  the  Company’s  capital  stock,  incur  liens  on  assets,  engage  in  certain  sale  and  leaseback 
transactions or sell certain assets, and (ii) the Company’s and any guarantor’s ability to sell all or substantially all of its assets 
to, or merge or consolidate with or into, other persons, in the case of each of the foregoing, subject to certain qualifications and 
exceptions, including the termination of certain of these covenants upon the Notes receiving investment grade credit ratings.

The Notes Indenture contains certain events of default, including, among other things, failure to make required payments, 
failure  to  comply  with  certain  agreements  or  covenants,  failure  to  pay  or  acceleration  of  certain  other  indebtedness,  certain 
events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the Notes Indenture will 
allow  either  the  Trustee  or  the  holders  of  at  least  25%  in  aggregate  principal  amount  of  the  applicable  series  of  the  then-
outstanding  Notes  to  accelerate,  or  in  certain  cases,  will  automatically  cause  the  acceleration  of  the  amounts  due  under  the 
applicable series of Notes.

Covenant Compliance

We were in compliance with all relevant covenants and restrictions contained in our debt agreements as of December 31, 

2020.

Contractual Cash Obligations and Other Commercial CommitmentsThe following table summarizes our contractual obligations at December 31, 2020, including interest, and the effect such obligations are expected to have on liquidity and cash flow in future periods.20212022 to 20232024 to 20252026 - AfterTotal(In millions)     Contractual cash obligations (including interest):      Debt, excluding debt discount and debt issuance costs$ 529.9 $ 1,020.4 $ 2,108.2 $ 1,326.8 $ 4,985.3   Interest on indebtedness(1) 246.4  479.9  368.3  240.2  1,334.7   Non-cancelable operating leases 155.1  228.6  119.6  124.1  627.4 Transition tax installments 2.6  8.7  38.3  13.7  63.3 Deferred compensation liability(2) 55.2  17.3  —  —  72.5 Pension plans(3) 29.5  —  —  —  29.5 Total contractual cash obligations$ 1,018.6 $ 1,754.9 $ 2,634.4 $ 1,704.8 $ 7,112.7 (1) Interest on the variable rate debt was calculated using the rates and balances outstanding at December 31, 2020.(2) WESCO Distribution and Anixter Inc. each sponsor a deferred compensation plan that permits select employees to make pre-tax deferrals of salary and bonus. The plans provide for benefit payments upon retirement, death, disability, termination or other scheduled dates determined by the participant. As a result of the termination of the Anixter Inc. deferred compensation plan, we estimate that $45.1 million of lump sum payments will be made directly to participants of this plan in 2021.(3) The majority of our various pension plans are non-contributory and, with the exception of the U.S. and Canada, cover substantially all full-time employees in their respective countries. Retirement benefits are provided based on compensation as defined in the plans. Our policy is to fund these plans as required by the Employee Retirement Income Security Act, the Internal Revenue Service and local statutory law. We currently estimate that we will contribute $11.4 million to our foreign pension plans in 2021. Due to the future impact of various market conditions, rates of return and changes in plan participants, we cannot provide a meaningful estimate of our future contributions beyond 2021. In addition, as a result of the termination of our two domestic non-qualified pension plans, we estimate that $18.1 million of lump sum payments will be made directly to participants of those plans during 2021.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.Liabilities related to unrecognized tax benefits, including interest and penalties, of $75.1 million were excluded from the table above as we cannot reasonably estimate the timing of these potential cash settlements with taxing authorities. See Note 12, “Income Taxes” in our Notes to Consolidated Financial Statements for further information related to unrecognized tax benefits.InflationThe 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. For the year ended December 31, 2020, pricing related to inflation did not have a material impact on our sales.SeasonalityOur operating results are not significantly affected by seasonal factors. Sales during the first and fourth quarters are usually affected by a reduced level of activity due to the impact of weather on projects. 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 StandardsSee Note 2, "Accounting Policies" of the Notes to Consolidated Financial Statements for information regarding the effect of new accounting pronouncements.Guarantor Financial StatementsWESCO Distribution (the “Issuer”) has outstanding $500 million in aggregate principal amount of 5.375% Senior Notes due 2021 (the “2021 Notes”) and $350 million in aggregate principal amount of 5.375% Senior Notes due 2024 (the “2024 Notes” and, together with the 2021 Notes, the “Notes”).Table of Contents41Table of Contents

The  Notes  are  unsecured  senior  obligations  of  WESCO  Distribution  and  are  fully  and  unconditionally  guaranteed  on  a 
senior unsecured basis by WESCO International and Anixter Inc. (the “Guarantors”), ranking pari passu in right of payment 
with  all  other  existing  and  future  senior  obligations  of  the  Issuer,  including  obligations  under  other  unsubordinated 
indebtedness. The Notes are effectively subordinated to all existing and future obligations of the Issuer that are secured by liens 
on  any  property  or  assets  of  the  Issuer,  including  the  Issuer’s  Revolving  Credit  Facility  and  the  then  outstanding  term  loan 
facility (the “Senior Secured Credit Facilities”), to the extent of the value of the collateral securing such obligations, and are 
structurally subordinated to all liabilities (including trade payables) of any of the Guarantors’s or the Issuer’s subsidiaries (the 
“non-Guarantor Subsidiaries”) and senior in right of payment to all existing and future obligations of the Issuer that are, by their 
terms, subordinated in right of payment to the Notes.

The  Notes  are  guaranteed  by  the  Guarantors  and  not  by  the  non-Guarantor  Subsidiaries.  In  the  event  of  a  bankruptcy, 
liquidation or reorganization of any of the non-Guarantor Subsidiaries, such non-Guarantor Subsidiaries will pay the holders of 
their debt and their trade creditors before they will be able to distribute or contribute, as the case may be, any of their assets to 
the  Issuer  or  the  Guarantors.  Therefore,  the  Notes  and  the  guarantee  of  the  Guarantors  (the  “Guarantee”)  are  effectively 
subordinated to the liabilities of the non-Guarantor Subsidiaries.

The Guarantee constitutes a senior obligation of the Guarantors, ranking pari passu in right of payment with all other senior 
obligations  of  the  Guarantors,  including  obligations  under  other  unsubordinated  indebtedness.  The  Guarantee  is  effectively 
subordinated to all existing and future obligations incurred by the Guarantors that are secured by liens on any property or assets 
of  the  Guarantors,  including  the  Senior  Secured  Credit  Facilities,  to  the  extent  of  the  value  of  the  collateral  securing  such 
obligations, structurally subordinated to all liabilities (including trade payables) of the non-Guarantor Subsidiaries and senior in 
right  of  payment  to  all  existing  and  future  obligations  of  the  Guarantors  that  are,  by  their  terms,  subordinated  in  right  of 
payment to the Guarantee.

The Guarantors guarantee to each holder of the Notes and to the respective trustees (i) the due and punctual payment of the 
principal  of,  premium,  if  any,  and  interest  on  each  Note,  when  and  as  the  same  shall  become  due  and  payable,  whether  at 
maturity, by acceleration or otherwise, the due and punctual payment of interest on the overdue principal and interest on the 
Notes, to the extent lawful, and the due and punctual payment of all other obligations and due and punctual performance of all 
obligations of the Issuer to the holders or the respective trustee all in accordance with the terms of the Notes and the indentures 
governing  the  Notes  and  (ii)  in  the  case  of  any  extension  of  time  of  payment  or  renewal  of  any  Notes  or  any  of  such  other 
obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or 
renewal, at stated maturity, by acceleration or otherwise.

If  the  Issuer  becomes  a  debtor  in  a  case  under  the  U.S.  Bankruptcy  Code  or  encounters  other  financial  difficulty,  under 
federal or state fraudulent transfer law, a court may void, subordinate or otherwise decline to enforce the Notes. A court might 
do so if it is found that when the Issuer issued the Notes, or in some states when payments became due under the Notes, the 
Issuer received less than reasonably equivalent value or fair consideration and either: (i) were insolvent or rendered insolvent by 
reason of such incurrence; (ii) were left with inadequate capital to conduct its business; or (iii) believed or reasonably should 
have believed that the Issuer would incur debts beyond its ability to pay.

The court might also void an issuance of the Notes without regard to the above factors, if the court found that the Issuer 
issued the Notes with actual intent to hinder, delay or defraud its creditors. A court would likely find that the Issuer did not 
receive  reasonably  equivalent  value  or  fair  consideration  for  the  Notes,  if  the  Issuer  did  not  substantially  benefit  directly  or 
indirectly from the issuance of the Notes. If a court were to void the issuance of the Notes, holders would no longer have any 
claim  against  the  Issuer.  Sufficient  funds  to  repay  the  Notes  may  not  be  available  from  other  sources.  In  addition,  the  court 
might direct holders to repay any amounts that they already received from the Issuer.

The following tables present summarized financial information for WESCO International, WESCO Distribution and Anixter Inc. on a combined basis after elimination of (i) intercompany transactions and balances among such entities and (ii) equity in earnings from and investments in any subsidiary that is a non-guarantor.

Quantitative and Qualitative Disclosures about Market Risks.Foreign Currency RisksApproximately 25% of our sales in 2020 were from our foreign subsidiaries and are denominated in foreign currencies. Our exposure to currency rate fluctuations primarily relate to Canada (Canadian dollar), Europe (euro, British pound, Swedish krona and Swiss franc) and Australia (dollar). We also have exposure to currency rate fluctuations related to more volatile markets including Argentina (peso), Brazil (real), Chile (peso), Colombia (peso), Mexico (peso), and Turkey (lira). 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.Table of Contents43Table of Contents

We  purchase  foreign  currency  forward  contracts  to  minimize  the  effect  of  fluctuating  foreign  currency-denominated 
accounts on our reported income. The foreign currency forward contracts are not designated as hedges for accounting purposes. 
At  December  31,  2020,  the  gross  and  net  notional  amounts  of  foreign  currency  forward  contracts  outstanding  were 
approximately  $111.9  million.  We  prepared  a  sensitivity  analysis  of  our  foreign  currency  forward  contracts  assuming  a  10% 
adverse change in the value of foreign currency contracts outstanding. The hypothetical adverse changes would have resulted in 
recording a $11.2 million loss in 2020. However, since these forward contracts are intended to be effective economic hedges, 
we would record offsetting gains as a result of the remeasurement of the underlying foreign currency denominated monetary 
amounts being hedged.

Interest Rate Risk

Fixed Rate Borrowings: As of December 31, 2020, approximately 75% of our debt portfolio is comprised of fixed rate debt. 
As  our  2021  Notes,  Anixter  2023  Senior  Notes,  2024  Notes,  2025  Notes,  Anixter  2025  Senior  Notes,  and  2028  Notes  were 
issued at fixed rates, interest expense would not be impacted by interest rate fluctuations. However, the fair value of our fixed 
rate  debt  will  generally  fluctuate  with  movements  of  interest  rates,  increasing  in  periods  of  declining  rates  of  interest  and 
declining in periods of increasing rates of interest. The fair value of our debt instruments with fixed interest rates is disclosed in 
Note 4, "Fair Value of Financial Instruments" of our Notes to Consolidated Financial Statements.

Floating  Rate  Borrowings:  Our  variable  rate  borrowings  are  comprised  of  the  Revolving  Credit  Facility,  the  Receivables 
Facility, and international lines of credit. The fair value of these debt instruments at December 31, 2020 approximated carrying 
value.  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 spreads, whereas borrowings under the 
Receivables Facility bear interest at the 30-day LIBOR rate, with a LIBOR floor of 0.5%, plus applicable spreads. A 100 basis 
point  increase  or  decrease  in  interest  rates  would  not  have  a  significant  impact  on  future  earnings  under  our  current  capital 
structure.

Defined  Benefit  Pension  Plans:  At  the  end  of  each  fiscal  year,  we  determine  the  interest  rate  to  discount  pension  plan 
liabilities to their present value. The discount rate reflects the current rate at which the pension liabilities could be effectively 
settled at the end of the year. In estimating this rate at the end of 2020, we reviewed rates of return on relevant market indices 
and concluded that the Willis Towers Watson Global Rate Link Model was consistent with observable market conditions and 
industry standards for developing spot rate curves. At December 31, 2020, we determined the consolidated weighted-average 
discount rate of all plans was 2.2% and used this rate to measure the projected benefit obligation. Due to its long duration, the 
pension liability is sensitive to changes in the discount rate. As a sensitivity measure, the effect of a 50-basis-point decline in 
the assumed discount rate would result in an increase in the expense for 2021 of approximately $1.0 million, and an increase in 
the projected benefit obligations at December 31, 2020 of $80.0 million. The impact of a 50-basis-point increase in the assumed 
discount rate would result in a decrease in the expense for 2021 of approximately $1.0 million, and a decrease in the projected 
benefit obligations of $71.0 million.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We  have  audited  the  accompanying  consolidated  balance  sheets  of  WESCO  International,  Inc.  and  its  subsidiaries  (the 
“Company”) as of December 31, 2020 and 2019, and the related consolidated statements of income and comprehensive income, 
of  stockholders’  equity  and  of  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2020,  including  the 
related notes and schedule of valuation and qualifying accounts for each of the three years in the period ended December 31, 
2020  appearing  after  Item  15  (collectively  referred  to  as  the  “consolidated  financial  statements”).  We  also  have  audited  the 
Company's internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control - 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In  our  opinion,  the  consolidated  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  financial 
position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the 
three years in the period ended December 31, 2020 in conformity with accounting principles generally accepted in the United 
States  of  America.  Also  in  our  opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over 
financial reporting as of December 31, 2020, based on criteria established in Internal Control - Integrated Framework (2013) 
issued by the COSO.

Change in Accounting Principle

As  discussed  in  Note  2  to  the  consolidated  financial  statements,  the  Company  changed  the  manner  in  which  it  accounts  for 
leases in 2019.

Basis for Opinions

The  Company's  management  is  responsible  for  these  consolidated  financial  statements,  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  the  Company’s  consolidated  financial  statements  and  on  the  Company's  internal  control  over  financial 
reporting  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight 
Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. 
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audits  to  obtain  reasonable  assurance  about  whether  the  consolidated  financial  statements  are  free  of  material  misstatement, 
whether  due  to  error  or  fraud,  and  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all  material 
respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement 
of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. 
Such  procedures  included  examining,  on  a  test  basis,  evidence  regarding  the  amounts  and  disclosures  in  the  consolidated 
financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by 
management,  as  well  as  evaluating  the  overall  presentation  of  the  consolidated  financial  statements.  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 described in Management’s Report on Internal Control Over Financial Reporting, management has excluded Anixter Inc. 
(the surviving entity of the Anixter International Inc. acquisition) from its assessment of internal control over financial reporting 
as of December 31, 2020 because it was acquired by the Company in a purchase business combination during 2020. We have 
also excluded Anixter Inc. from our audit of internal control over financial reporting. Anixter Inc. is a wholly-owned subsidiary 
whose total assets and total net sales excluded from management’s assessment and our audit of internal control over financial 
reporting represent 30% and 37%, respectively, of the related consolidated financial statement amounts as of and for the year 
ended December 31, 2020.

Definition and Limitations of Internal Control over Financial Reporting

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 

46

Table of Contents

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.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial 
statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or 
disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or 
complex  judgments.  The  communication  of  critical  audit  matters  does  not  alter  in  any  way  our  opinion  on  the  consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate 
opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Interim Goodwill Impairment Assessments

As described in Notes 2 and 5 to the consolidated financial statements, the Company’s goodwill balance was $3,187 million as 
of December 31, 2020. Goodwill is tested by management for impairment annually during the fourth quarter or more frequently 
if triggering events occur indicating that the carrying value may not be recoverable. Certain triggering events occurred during 
the  first  quarter  of  2020,  including  the  effect  of  the  ongoing  macroeconomic  disruption  and  uncertainty  caused  by  the 
COVID-19 pandemic, as well as the decline in the Company’s share price and market capitalization, both of which indicated 
that  the  carrying  value  of  goodwill  may  not  be  recoverable.  Accordingly,  the  Company  performed  an  interim  test  for 
impairment  as  of  March  31,  2020.  Additionally,  the  Company  identified  new  operating  segments  during  the  third  quarter  of 
2020, which changed the composition of its reporting units. Accordingly, the Company performed a goodwill impairment test 
immediately  before  and  after  it  reorganized  its  reporting  structure.  There  were  no  impairment  losses  identified  as  a  result  of 
these interim tests. Management 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. Fair value is estimated using a discounted cash flow analysis approach. 
Management applied significant judgment related to these fair value techniques, which included the selection of an expected 
operating margin for each year in the forecast and discount rate assumptions.

The  principal  considerations  for  our  determination  that  performing  procedures  relating  to  the  interim    goodwill  impairment 
assessments  is  a  critical  audit  matter  are  (i)  the  significant  judgment  by  management  when  developing  the  fair  value 
measurements of the reporting units; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures 
and evaluating management’s significant assumptions related to the expected operating margins and discount rates; and (iii) the 
audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall 
opinion  on  the  consolidated  financial  statements.  These  procedures  included  testing  the  effectiveness  of  controls  relating  to 
management’s interim goodwill impairment assessments, including controls over the determination of the fair value for each 
reporting unit. These procedures also included, among others (i) evaluating the appropriateness of the valuation techniques used 
in  management’s  estimates;  (ii)  testing  the  completeness  and  accuracy  of  underlying  data  used  in  the  techniques;  and  (iii) 
evaluating  the  significant  assumptions  used  by  management  related  to  the  expected  operating  margins  and  discount  rates. 
Evaluating  whether  management’s  assumptions  related  to  the  expected  operating  margins  were  reasonable  involved 
consideration of (i) the current and past performance of each reporting unit; (ii) consistency with external market and industry 
data; and (iii) consistency with evidence obtained in other areas of the audit. Professionals with specialized skill and knowledge 
were used to assist in the evaluation of the Company’s discount rate assumptions.

Customer Relationship Intangible Assets Recognized in Connection with the Acquisition of Anixter International Inc.

As  described  in  Notes  2  and  6  to  the  consolidated  financial  statements,  the  Company  completed  the  acquisition  of  Anixter 
International Inc. for net consideration of $3.7 billion in 2020, which resulted in $1.1 billion of customer relationship intangible 
assets  being  recorded.  Fair  value  of  the  customer  relationship  intangible  assets  was  estimated  using  the  multi-period  excess 
earnings method. Management applied significant judgement related to this fair value technique, which included the selection 
of  an  expected  operating  margin  assumption  for  each  year  in  the  forecast,  and  customer  attrition  rate  and  discount  rate 
assumptions.

management  related  to  the  expected  operating  margins,  customer  attrition  rates,  and  discount  rates.  Evaluating  whether 
management’s  assumptions  related  to  the  expected  operating  margins  and  customer  attrition  rates  were  reasonable  involved 
consideration of (i) the past performance of the acquired businesses; (ii) consistency with external market and industry data; and 
(iii)  consistency  with  evidence  obtained  in  other  areas  of  the  audit.  Professionals  with  specialized  skill  and  knowledge  were 
used to assist in the evaluation of the appropriateness of the valuation methods, the customer attrition rates, and the discount 
rates.

1. ORGANIZATION

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

WESCO  International,  Inc.  ("WESCO  International")  and  its  subsidiaries  (collectively,  “WESCO”  or  the  "Company"), 
headquartered  in  Pittsburgh,  Pennsylvania,  is  a  leading  provider  of  business-to-business  distribution,  logistics  services  and 
supply chain solutions.

On  June  22,  2020,  WESCO  completed  its  previously  announced  acquisition  of  Anixter  International  Inc.,  a  Delaware 
corporation  (“Anixter”).  Pursuant  to  the  terms  of  the  Agreement  and  Plan  of  Merger,  dated  January  10,  2020  (the  “Merger 
Agreement”),  by  and  among  Anixter,  WESCO  and  Warrior  Merger  Sub,  Inc.,  a  Delaware  corporation  and  a  wholly  owned 
subsidiary of WESCO (“Merger Sub”), Merger Sub was merged with and into Anixter (the “Merger”), with Anixter surviving 
the Merger and continuing as a wholly owned subsidiary of WESCO. On June 23, 2020, Anixter merged with and into Anixter 
Inc., with Anixter Inc. surviving to become a wholly owned subsidiary of WESCO.

2. ACCOUNTING POLICIES

Basis of Presentation

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.

At the beginning of the third quarter of 2020, in connection with the acquisition of Anixter, the Company identified new 
operating  segments.  These  operating  segments,  which  have  been  organized  around  three  strategic  business  units,  consist  of 
Electrical & Electronic Solutions ("EES"), Communications & Security Solutions ("CSS") and Utility & Broadband Solutions 
("UBS"). The Company's operating segments, which are equivalent to its reportable segments, are described further in Note 17, 
"Business  Segments".  The  applicable  comparative  financial  information  reported  in  the  Company's  previously  issued 
consolidated financial statements for the years ended December 31, 2019 and 2018 has been recast in this Annual Report on 
Form 10-K to conform to the basis of the new segments.

Out-of-Period Adjustment

In  the  fourth  quarter  of  2020,  management  determined  that  the  Company’s  inventories  were  overstated  by  $60.3  million 
because  of  a  misstatement  in  inventory  cost  absorption  accounting,  which  occurred  over  multiple  periods  and  also  impacted 
inventories acquired in business combinations during those periods. Accordingly, the Consolidated Balance Sheet at December 
31, 2020 reflects a reduction to inventories of $60.3 million, an increase to goodwill of $33.9 million and a decrease to deferred 
income tax liabilities of $12.0 million. The resulting effect of the out-of-period adjustment on the Consolidated Statement of 
Income and Comprehensive Income for the year ended December 31, 2020 was a $18.9 million increase to cost of goods sold, 
which decreased net income for the year by $14.4 million. Management concluded that this misstatement is not material to the 
current period or the financial statements of any previously filed annual or interim periods.

Reclassifications

The  Consolidated  Balance  Sheet  as  of  December  31,  2019,  the  Consolidated  Statements  of  Income  and  Comprehensive 
Income  for  the  years  ended  December  31,  2019  and  2018,  and  the  Consolidated  Statements  of  Cash  Flows  for  the  years 
ended December 31, 2019 and 2018, respectively, include certain reclassifications to previously reported amounts to conform to 
the current period's presentation.

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  notes.  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.

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

Revenue Recognition

WESCO’s revenue arrangements generally consist of single performance obligations to transfer a promised good or service, 
or  a  combination  of  goods  and  services.  Revenue  is  measured  as  the  amount  of  consideration  WESCO  expects  to  receive  in 
exchange  for  transferring  goods  or  providing  services.  Revenue  is  recognized  when  control  has  transferred  to  the  customer, 
which is generally when the product has shipped from a WESCO facility or directly from a supplier. However, transfer may 
occur at a later date depending on the agreed upon terms, such as delivery at the customer's designated location, or based on 
consignment terms. For products that ship directly from suppliers to customers, WESCO acts as the principal in the transaction 
and  recognizes  revenue  on  a  gross  basis.  When  providing  services,  sales  are  recognized  over  time  as  control  transfers  to  the 
customer, which occurs as services are rendered. WESCO generally satisfies its performance obligations within a year or less.

WESCO generally does not have significant financing terms associated with its contracts; payments are normally received 
within 60 days. There are generally no significant costs associated with obtaining customer contracts. WESCO typically passes 
through  warranties  offered  by  manufacturers  or  suppliers  to  its  customers.  Sales  taxes  (and  value  added  taxes  in  foreign 
jurisdictions) collected from customers and remitted to governmental authorities are excluded from net sales.

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 based on forecasted purchases and the rebate provisions of the various supplier contracts. The corresponding 
rebate  income  is  recorded  as  a  reduction  to  cost  of  goods  sold.  Receivables  under  the  supplier  rebate  program  were  $136.7 
million at December 31, 2020 and $81.6 million at December 31, 2019. The supplier volume rebate income as a percentage of 
net sales was 1.1% in 2020, 1.2% in 2019 and 1.3% in 2018.

Cash Equivalents

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

Allowance for Expected Credit Losses

WESCO recognizes expected credit losses resulting from the inability of its customers to make required payments through 
an allowance account that is measured each reporting date. WESCO estimates credit losses over the life of its trade accounts 
receivable  using  a  combination  of  historical  loss  data,  current  credit  conditions,  specific  customer  circumstances,  and 
reasonable and supportable forecasts of future economic conditions. The allowance for expected credit losses was $23.9 million 
at  December  31,  2020  and  $25.4  million  at  December  31,  2019.  The  total  amount  recorded  as  selling,  general  and 
administrative  expense  related  to  credit  losses  was  $10.1  million,  $7.0  million  and  $10.9  million  for  2020,  2019  and  2018, 
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  reduces  the  carrying  value  of  its  inventories  at  the 
earlier of identifying an item that is considered to be obsolete or in excess of supply relative to demand, or no movement in the 
past 15 months. Reserves for excess and obsolete inventories were $28.7 million and $30.7 million at December 31, 2020 and 
2019,  respectively.  The  total  expense  related  to  excess  and  obsolete  inventories,  included  in  cost  of  goods  sold,  was  $15.7 
million, $10.0 million and $9.7 million for 2020, 2019 and 2018, respectively.

Property, Buildings and Equipment

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

Costs incurred during the application development stage of internally developing software are capitalized and are reported at 
the lower of unamortized cost or net realizable value. Costs incurred during the preliminary project and post-implementation 
stages  are  expensed  as  incurred.  Capitalized  costs  include  external  direct  costs  of  materials  and  services  consumed  in 
developing internal-use computer software, payroll and payroll-related costs for employees who are directly associated with and 
who devote time to the internal-use computer software project and interest costs. Internal-use computer software is amortized 
using the straight-line method over its estimated useful life, typically three to seven years.

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 resulting gains or losses are recorded and reported as selling, general and 
administrative expenses.

Of WESCO’s $399.2 million net book value of property, buildings and equipment as of December 31, 2020, $144.1 million 
consists  of  land,  buildings  and  leasehold  improvements  that  are  geographically  dispersed  among  WESCO’s  800  branches, 
warehouses  and  sales  offices,  mitigating  the  risk  of  impairment.  WESCO  assesses  its  long-lived  assets  for  impairment 
whenever events or changes in circumstances indicate that the carrying amount of any such assets may not be fully recoverable. 
Changes  in  circumstances  include  technological  advances,  changes  in  the  business  model,  capital  structure,  economic 
conditions  or  operating  performance.  The  evaluation  is  based  upon,  among  other  things,  utilization,  serviceability  and 
assumptions developed by management, which are categorized as Level 3 of the fair value hierarchy, related to the estimated 
future undiscounted cash flows that 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, an impairment loss is recognized to the extent that carrying value exceeds 
fair value.  Management applies its best judgment when performing these evaluations.

Leases

The  determination  of  whether  an  arrangement  is,  or  contains,  a  lease  is  performed  at  the  inception  of  the  arrangement. 
Classification and initial measurement of the right-of-use asset and lease liability are determined at the lease commencement 
date. The Company elected the short-term lease measurement and recognition exemption; therefore, leases with an initial term 
of 12 months or less are not recorded on the balance sheet. Operating lease expense is recognized on a straight-line basis over 
the lease term.

Operating  lease  assets  and  liabilities  are  recognized  at  the  commencement  date  based  on  the  present  value  of  the  future 
minimum  lease  payments.  Certain  leases  contain  rent  escalation  clauses  that  are  either  fixed  or  adjusted  periodically  for 
inflation or market rates and such clauses are factored into the Company's determination of lease payments. WESCO also has 
variable lease payments that do not depend on a rate or index, primarily for items such as common area maintenance and real 
estate taxes, which are recorded as variable expense when incurred. The operating lease asset includes advance payments and 
excludes incentives and initial direct costs incurred.

The Company's arrangements include certain non-lease components such as common area and other maintenance for leased 
real estate, as well as mileage, fuel and maintenance costs related to leased automobiles and trucks. WESCO accounts for these 
nonlease components separately from the associated lease components. The Company does not guarantee any residual value in 
its  lease  agreements,  and  there  are  no  material  restrictions  or  covenants  imposed  by  lease  arrangements.  Real  estate  leases 
typically  include  one  or  more  options  to  extend  the  lease,  or  terminate  early.  The  Company  regularly  evaluates  the  renewal 
options, and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term. For most 
of  WESCO’s  leases,  the  discount  rate  implicit  in  the  lease  is  not  readily  determinable.  Accordingly,  the  Company  uses  its 
incremental borrowing rate based on the information available at the lease commencement date to discount lease payments to 
the present value.

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.  The  Company  first  assesses 
qualitative  factors,  including  macroeconomic  conditions,  industry  and  market  considerations,  cost  factors,  overall  financial 
performance, other relevant events such as changes in key personnel, changes in the composition or carrying amount of the net 
assets of a reporting unit, and sustained decreases in share price, to determine whether it is more likely than not that the fair 
value of WESCO's reporting units are less than their carrying values. If the qualitative assessment indicates that the fair values 
of the Company's reporting units may not exceed their respective carrying values, then WESCO performs a quantitative test for 
impairment by comparing the fair value of each reporting unit to its carrying value. The Company determines the fair values of 
its  reporting  units  using  a  discounted  cash  flow  analysis  and  consideration  of  market  multiples.  The  discounted  cash  flow 
analysis  uses  certain  assumptions,  including  expected  operating  margins  supported  by  a  combination  of  historical  results, 
current forecasts, market data and recent economic events, which are categorized within Level 3 of the fair value hierarchy. The 
Company  uses  a  discount  rate  that  reflects  market  participants'  cost  of  capital.  WESCO  evaluates  the  recoverability  of 
indefinite-lived  intangible  assets  using  the  relief-from-royalty  method  based  on  projected  financial  information.  At 
December 31, 2020 and 2019, goodwill and indefinite-lived trademarks totaled $4.0 billion and $1.9 billion, respectively.

Table of Contents

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

The  determination  of  fair  value  involves  significant  management  judgment,  particularly  as  it  relates  to  the  underlying 
assumptions  and  factors  around  expected  operating  margins  and  discount  rate.  Management  applies  its  best  judgment  when 
assessing the reasonableness of financial projections. Fair values 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

Definite  lived  intangible  assets  are  amortized  over  2  to  20  years.  Certain  customer  relationships  are  amortized  using  an 
accelerated method whereas all other definite lived intangible assets subject to amortization use a straight-line method. In either 
case,  the  amortization  method  reflects  the  pattern  in  which  the  economic  benefits  of  the  respective  assets  are  consumed  or 
otherwise  used.  WESCO  continually  evaluates  whether  events  or  circumstances  have  occurred  that  would  indicate  the 
remaining estimated useful lives of definite lived intangible assets require revision or that the remaining carrying value of such 
assets may not be recoverable.

Insurance Programs

WESCO  uses  commercial  insurance  for  auto,  workers’  compensation,  casualty  and  health  claims,  and  information 
technology  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 insurance programs was $27.9 million and $12.9 million at 
December 31, 2020 and 2019, 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 taxable 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.

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  recognized  in  the  consolidated  financial  statements.  WESCO  recognizes  interest  and  penalties  related  to 
uncertain tax benefits as part of interest expense and income tax expense, respectively.

The  Tax  Cuts  and  Jobs  Act  of  2017  (the  “TCJA”)  imposed  a  one-time  tax  on  the  deemed  repatriation  of  undistributed 
foreign earnings (the “transition tax”). Except for a portion of foreign earnings previously taxed in the U.S. that can effectively 
be distributed without further material U.S. or foreign taxation, the Company continues to assert that the undistributed earnings 
of  its  foreign  subsidiaries  are  indefinitely  reinvested.  To  the  extent  the  earnings  of  the  Company's  foreign  subsidiaries  are 
distributed in the form of dividends, such earnings may be subject to additional taxes. The Company believes that it is able to 
maintain a sufficient level of liquidity for its domestic operations and commitments without incurring any material tax cost to 
repatriate cash held by its foreign subsidiaries.

The  provisions  of  the  TCJA  also  introduced  U.S.  taxation  on  certain  global  intangible  low-taxed  income  ("GILTI"). 

WESCO has elected to account for GILTI tax as a component of income tax expense.

Foreign Currency

The local currency is the functional currency for most of the Company's operations outside the U.S. 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

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). 
Unrealized  gains  and  losses  related  to  the  Company's  defined  benefit  pension  obligations  are  recognized  as  a  component  of 
other comprehensive income (loss) within stockholders' equity.

Fair Value of Financial Instruments

The Company measures the fair value of assets and liabilities on a recurring and nonrecurring basis according to 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  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,  and 
Level 3 inputs are unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own 
assumptions.  The  hierarchy  gives  the  highest  priority  to  unadjusted  quoted  prices  in  active  markets  for  identical  assets  or 
liabilities (Level 1) and the lowest priority to measurements involving significant unobservable inputs (Level 3).

The  Company  measures  the  fair  values  of  goodwill,  intangible  assets  and  property,  buildings  and  equipment  on  a 

nonrecurring basis if required by impairment tests applicable to these assets, as described above.

Other, net

Other non-operating income and expenses ("other, net") primarily includes the non-service cost components of net periodic 

pension cost (benefit) and foreign exchange gains and losses.

Recently Adopted Accounting Pronouncements

Effective  January  1,  2019,  WESCO  adopted  Accounting  Standards  Update  (ASU)  2016-02,  Leases,  and  all  the  related 
amendments (“Topic 842”), a comprehensive new standard that amended various aspects of existing accounting guidance for 
leases. The adoption of Topic 842 resulted in the recognition of right-of-use assets and lease liabilities for operating leases of 
approximately $240 million and $245 million, respectively, in the Consolidated Balance Sheet as of January 1, 2019, most of 
which relate to real estate. The adoption of Topic 842 did not have a material impact on the Consolidated Statements of Income 
and Comprehensive Income or Consolidated Statements of Cash Flows for the year ended December 31, 2019.

The Company used the optional effective date transition method and therefore did not adjust the prior comparative periods 
presented herein. There was no cumulative-effect adjustment to beginning retained earnings as a result of using this method. In 
addition, the Company elected the package of practical expedients that allowed the adoption of Topic 842 without reassessing 
arrangements  that  commenced  prior  to  the  effective  date.  Additional  qualitative  and  quantitative  information  about  the 
Company's leases is disclosed in Note 9, "Leases".

In  June  2016,  the  Financial  Accounting  Standards  Board  ("FASB")  issued  ASU  2016-13,  Financial  Instruments—Credit 
Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial  Instruments,  which  introduced  new  guidance  for  the 
accounting for credit losses on certain financial instruments. The Company adopted this ASU effective January 1, 2020. The 
adoption  of  this  new  credit  loss  guidance  did  not  have  a  material  impact  on  the  consolidated  financial  statements  and  notes 
thereto  presented  herein,  and  WESCO  does  not  expect  it  to  have  a  material  impact  on  its  financial  position  or  results  of 
operation on an ongoing basis.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes 
to  the  Disclosure  Requirements  for  Fair  Value  Measurement,  which  amends  the  disclosure  requirements  for  recurring  and 
nonrecurring fair value measurements by removing, modifying and adding certain disclosures. The Company adopted this ASU 
in  the  first  quarter  of  2020.  The  adoption  of  this  guidance  did  not  have  a  material  impact  on  the  consolidated  financial 
statements and notes thereto presented herein.

In  August  2018,  the  FASB  issued  ASU  2018-15,  Intangibles—Goodwill  and  Other—Internal-Use  Software  (Subtopic 
350-40):  Customer’s  Accounting  for  Implementation  Costs  Incurred  in  a  Cloud  Computing  Arrangement  That  Is  a  Service 
Contract,  which  aligned  the  requirements  for  capitalizing  implementation  costs  incurred  in  a  hosting  arrangement  that  is  a 
service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. 
The  standard  was  effective  for  fiscal  years  beginning  after  December  15,  2019.  The  Company  adopted  this  ASU  in  the  first 
quarter of 2020. The adoption of this guidance did not have a material impact on the consolidated financial statements and notes 
thereto presented herein.

57

In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans, which amends the disclosure requirements for all employers that sponsor defined benefit pension and other post retirement plans by removing and adding certain disclosures. The amendments in this ASU are effective for fiscal years ending after December 15, 2020. Early adoption is permitted. The Company adopted this ASU in the fourth quarter of 2020. The adoption of this guidance did not have a material impact on the consolidated financial statements and notes thereto presented herein.Recently Issued Accounting PronouncementsIn December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions to the general principles of Accounting Standards Codification Topic 740, Income Taxes, and simplifies other aspects of accounting for income taxes. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. Management does not expect the adoption of this accounting standard to have a material impact on its consolidated financial statements and notes thereto.In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. Management is currently evaluating the impact related to the replacement of London Interbank Offered Rate (LIBOR) and whether the Company will elect the adoption of the optional guidance.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.3. REVENUEWESCO distributes products and provides services to customers globally in various end markets within its business segments. The segments, which consist of Electrical & Electronic Solutions, Communications & Security Solutions, and Utility & Broadband Solutions operate in the United States, Canada and various other international countries.The following tables disaggregate WESCO’s net sales by segment and geography for the periods presented: Year Ended December 31,(In thousands)202020192018Electrical & Electronic Solutions$ 5,479,760 $ 4,860,541 $ 4,878,836 Communications & Security Solutions 3,323,264  909,496  857,481 Utility & Broadband Solutions 3,522,971  2,588,880  2,440,284 Total by segment$ 12,325,995 $ 8,358,917 $ 8,176,601  Year Ended December 31,(In thousands)202020192018United States$ 9,110,453 $ 6,234,119 $ 6,089,130 Canada  1,892,321  1,647,066  1,647,933 Other International (1) 1,323,221  477,732  439,538 Total by geography (2)$ 12,325,995 $ 8,358,917 $ 8,176,601 (1)   No individual other international country's net sales are material.(2) WESCO attributes revenues from external customers to individual countries on the basis of point of sale.In accordance with certain contractual arrangements, WESCO receives payment from its customers in advance and recognizes such payment as deferred revenue. Revenue for advance payment is recognized when the performance obligation has been satisfied and control has transferred to the customer, which is generally upon shipment. Deferred revenue is usually recognized within a year or less from the date of the customer’s advance payment. At December 31, 2020 and 2019, $24.3 million and $12.3 million, respectively, of deferred revenue was recorded as a component of other current liabilities in the Consolidated Balance Sheets.Table of ContentsWESCO INTERNATIONAL, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)58Table of Contents

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

WESCO’s revenues are adjusted for variable consideration, which includes customer volume rebates, returns, and discounts. 
WESCO measures variable consideration by estimating expected outcomes using analysis and inputs based upon historical data, 
as  well  as  current  and  forecasted  information.  Variable  consideration  is  reviewed  by  management  on  a  monthly  basis  and 
revenue  is  adjusted  accordingly.  Variable  consideration  reduced  revenue  for  the  years  ended  December  31,  2020,  2019  and 
2018 by approximately $269.5 million, $106.6 million and $107.4 million, respectively. As of December 31, 2020 and 2019, 
the Company's estimated product return obligation was $38.9 million and $4.4 million, respectively.

Shipping and handling costs are recognized in net sales when they are billed to the customer. These costs are recognized as a 
component of selling, general and administrative expenses when WESCO does not bill the customer. WESCO has elected to 
recognize shipping and handling costs as a fulfillment cost. Shipping and handling costs recorded as a component of selling, 
general and administrative expenses totaled $149.3 million, $71.7 million and $74.1 million for the years ended December 31, 
2020, 2019 and 2018, respectively.

4. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, accounts payable, 
bank  overdrafts,  outstanding  indebtedness,  foreign  currency  forward  contracts,  and  benefit  plan  assets.  The  fair  value  of  the 
Company's benefit plan assets is disclosed in Note 14, "Employee Benefit Plans" and except for outstanding indebtedness and 
foreign  currency  forward  contracts,  the  carrying  value  of  the  Company’s  remaining  financial  instruments  approximates  fair 
value.

The Company uses a market approach to determine the fair value of its debt instruments, utilizing quoted prices in active 
markets, interest rates and other relevant information generated by market transactions involving similar instruments. Therefore, 
the  inputs  used  to  measure  the  fair  value  of  the  Company's  debt  instruments  are  classified  as  Level  2  within  the  fair  value 
hierarchy.

The carrying value of WESCO's debt instruments with fixed interest rates was $3,730.1 million and $850.0 million as of 
December 31, 2020 and 2019, respectively. The estimated fair value of this debt was $4,084.7 million and $866.2 million as of 
December 31, 2020 and 2019, respectively. The reported carrying values of WESCO's indebtedness with variable interest rates 
approximated their fair values as of December 31, 2020 and 2019. The increase in carrying value and estimated fair value of 
fixed rate debt is primarily due to higher outstanding borrowings related to the Anixter merger.

The  Company  purchases  foreign  currency  forward  contracts  to  minimize  the  effect  of  fluctuating  foreign  currency-
denominated  accounts  on  its  earnings.  The  foreign  currency  forward  contracts  are  not  designated  as  hedges  for  accounting 
purposes. The Company's strategy is to negotiate terms for its derivatives and other financial instruments to be highly effective, 
such  that  the  change  in  the  value  of  the  derivative  offsets  the  impact  of  the  underlying  hedge.  Its  counterparties  to  foreign 
currency forward contracts have investment-grade credit ratings. The Company regularly monitors the creditworthiness of its 
counterparties to ensure no issues exist that could affect the value of its derivatives.

The Company does not hedge 100% of its foreign currency-denominated accounts. In addition, the results of hedging can 
vary  significantly  based  on  various  factors,  such  as  the  timing  of  executing  foreign  currency  forward  contracts  versus  the 
movement of currencies as well as the fluctuations in the account balances throughout each reporting period. The fair value of 
foreign currency forward contracts is based on the difference between the contract rate and the current exchange rate. The fair 
value  of  foreign  currency  forward  contracts  is  measured  using  observable  market  information.  These  inputs  would  be 
considered  Level  2  in  the  fair  value  hierarchy.  At  December  31,  2020,  foreign  currency  forward  contracts  were  revalued  at 
then-current  foreign  exchange  rates  with  the  changes  in  valuation  reflected  directly  in  other  non-operating  expenses  ("other, 
net") in the Consolidated Statements of Income and Comprehensive Income offsetting the transaction gain (loss) recorded on 
foreign currency-denominated accounts. At December 31, 2020, the gross and net notional amounts of foreign currency forward 
contracts outstanding were approximately $111.9 million. While all of the Company's foreign currency forward contracts are 
subject to master netting arrangements with its counterparties, assets and liabilities related to these contracts are presented on a 
gross basis within the Consolidated Balance Sheets. The gross fair values of assets and liabilities related to foreign currency 
forward contracts were immaterial.

Accordingly, the Company performed an interim test for impairment as of March 31, 2020. There were no impairment losses identified as a result of this interim test.As disclosed in Note 2, "Accounting Policies", the Company identified new operating segments during the third quarter of 2020, which changed the composition of its reporting units. Accordingly, the Company reassigned goodwill to the new reporting units using a relative fair value allocation approach. The Company performed a goodwill impairment test immediately before and after it reorganized its reporting structure. Goodwill was tested for impairment on a reporting unit level and the evaluation involved comparing the fair value of each reporting unit to its carrying value. The fair values of the Company's reporting units were determined using a discounted cash flow analysis, and consideration was also given to market multiples. In performing the quantitative assessments, management used expected operating margins supported by a combination of historical results, current forecasts, market data and recent economic events, which are categorized within Level 3 of the fair value hierarchy. The Company used a discount rate that reflects market participants' cost of capital. There were no impairment losses identified as a result of these tests. Although all of the Company's reorganized reporting units had fair values that exceeded the respective carrying values, the EES reporting unit with goodwill of $809.9 million had an estimated fair value that exceeded its respective carrying value by less than 10%. As a result, the EES reporting unit is more susceptible to impairment risk from adverse macroeconomic conditions and if such conditions were to persist the underlying cash flows used to estimate fair value may impact the recoverability of goodwill.Table of ContentsWESCO INTERNATIONAL, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)60The Company performed its annual impairment tests of goodwill and indefinite-lived intangible assets during the fourth quarter by assessing qualitative factors to determine whether it was more likely than not that the fair value of a reporting unit was less than its carrying amount. In performing this qualitative assessment, the Company assessed relevant events and circumstances, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, other relevant events such as changes in key personnel, changes in the composition or carrying amount of the net assets of a reporting unit, and sustained decreases in share price. As a result of this assessment, the Company determined that the fair values of its reporting units continued to exceed the respective carrying amounts and, therefore, a quantitative impairment test was unnecessary.The determination of fair value of the reporting units involves significant management judgment, particularly as it relates to the underlying assumptions and factors around expected operating margins and discount rate. Due to the ongoing uncertainty surrounding the current macroeconomic environment and conditions in the markets in which WESCO operates, as well as the risk that the Company may not fully realize cost savings, operating synergies or revenue improvement as a result of its acquisition of Anixter, there can be no assurance that the fair values of the Company's reporting units will exceed their carrying values in the future, and that goodwill and indefinite-lived intangible assets will be fully recoverable.Intangible AssetsThe components of intangible assets are as follows: December 31, 2020December 31, 2019Life (in years)Gross CarryingAmount (1)AccumulatedAmortization (1)NetCarryingAmountGross CarryingAmount (1)AccumulatedAmortization (1)NetCarryingAmount (In thousands)Intangible assets:      TrademarksIndefinite$ 833,793 $ — $ 833,793 $ 98,699 $ — $ 98,699 Customer relationships(2)10 -  20 1,434,554  (227,585)  1,206,969  358,341  (201,962)  156,379 Distribution agreements(2)10 - 19 29,212  (21,040)  8,172  37,371  (25,294)  12,077 Trademarks(2)10 - 15 24,898  (11,415)  13,483  24,800  (9,319)  15,481 Non-compete agreements2 - 5 4,462  (1,384)  3,078  196  (180)  16 Patents10 —  —  —  48,310  (43,687)  4,623   $ 2,326,919 $ (261,424) $ 2,065,495 $ 567,717 $ (280,442) $ 287,275 (1)Excludes the original cost and related accumulated amortization of fully-amortized intangible assets.(2)The net carrying amount as of December 31, 2020 excludes $1.0 million of trademarks, $3.3 million of customer relationships and $1.4 million of distribution agreements that are classified as held for sale, as disclosed in Note 7, "Assets and Liabilities Held for Sale".Amortization expense related to intangible assets totaled $66.5 million, $35.5 million and $35.9 million for the years ended December 31, 2020, 2019 and 2018, respectively.The following table sets forth the estimated amortization expense for intangible assets for the next five years and thereafter:For the year ending December 31,(In thousands)2021$ 86,619 2022 83,628 2023 81,400 2024 80,087 2025 76,829 Thereafter 823,139 Table of ContentsWESCO INTERNATIONAL, INC.

ACQUISITIONSAnixter International Inc.As described in Note 1, "Organization", on June 22, 2020, WESCO completed its previously announced merger with Anixter. The Company used the net proceeds from the issuance of senior unsecured notes, borrowings under its revolving credit facility and accounts receivable securitization facility (as described further in Note 10, "Debt"), as well as cash on hand, to finance the acquisition of Anixter and related transaction costs.At the effective time of the Merger, each outstanding share of common stock of Anixter (subject to limited exceptions) was converted into the right to receive (i) $72.82 in cash, (ii) 0.2397 shares of common stock of WESCO, par value $0.01 per share (the “WESCO Common Stock”) and (iii) 0.6356 depositary shares, each representing a 1/1,000th interest in a share of newly issued fixed-rate reset cumulative perpetual preferred stock of WESCO, Series A, with a $25,000 stated amount per whole preferred share and an initial dividend rate equal to 10.625%.Anixter is a leading distributor of network and security solutions, electrical and electronic solutions, and utility power solutions with locations in over 300 cities across approximately 50 countries, and 2019 annual sales of more than $8 billion. The Merger brought together two companies with highly compatible capabilities and characteristics. The combination of WESCO and Anixter created an enterprise with scale and should afford the Company the opportunity to digitize its business, and expand its services portfolio and supply chain offerings.The total preliminary estimated fair value of consideration transferred for the Merger consisted of the following:(In thousands)Cash portion attributable to common stock outstanding$ 2,476,010 Cash portion attributable to options and restricted stock units outstanding 87,375 Fair value of cash consideration 2,563,385 Common stock consideration 313,512 Series A preferred stock consideration 573,786 Fair value of equity consideration 887,298 Extinguishment of Anixter obligations, including accrued and unpaid interest 1,247,653 Total purchase consideration$ 4,698,336 Supplemental cash flow disclosure related to acquisitions:Cash paid for acquisition$ 3,811,038 Less: Cash acquired (103,463) Cash paid for acquisition, net of cash acquired$ 3,707,575 The Merger was accounted for as a business combination with WESCO acquiring Anixter in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations. Under the acquisition method of accounting, the preliminary purchase consideration was allocated to the identified assets acquired and liabilities assumed based on their respective acquisition date fair value, with any excess allocated to goodwill. The fair value estimates were based on income, market and cost valuation methods using primarily unobservable inputs developed by management, which are categorized within Level 3 of the fair value hierarchy. Specifically, the fair values of the identified trademark and customer relationship intangible assets were estimated using the relief-from-royalty and multi-period excess earnings methods, respectively. Significant inputs used to value these identifiable intangible assets included projected revenues and expected operating margins, customer attrition rates, discount rates, royalty rates, and applicable income tax rates. The excess purchase consideration recorded to goodwill is not deductible for income tax purposes, and has been assigned to the Company's reportable segments based on their relative fair values, as disclosed in Note 5, "Goodwill and Intangible Assets". The resulting goodwill is primarily attributable to Anixter's workforce, significant cross-selling opportunities in additional geographies, enhanced scale, and other operational efficiencies.Since the initial measurement of the identified assets acquired and liabilities assumed, the Company has recognized adjustments to inventories of $8.2 million, operating lease assets of $18.0 million, total identifiable intangible assets of $5.4 million, other noncurrent assets of $15.5 million, operating lease liabilities of $17.0 million, deferred income taxes of $27.5 million and other noncurrent liabilities of $38.7 million. Certain other measurement period adjustments were made to the identified assets acquired and liabilities assumed, none of which were significant, individually or in aggregate. The net impact of these adjustments was an increase to goodwill of $2.4 million.Table of ContentsWESCO INTERNATIONAL, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)62The estimated fair values of assets acquired and liabilities assumed are based on preliminary calculations and valuations using estimates and assumptions at the time of acquisition. The determination of the fair values of assets acquired and liabilities assumed, especially those related to identifiable intangible assets, is preliminary due to the complexity of combining multibillion dollar businesses. Accordingly, as the Company obtains additional information during the measurement period (not to exceed one year from the acquisition date), estimates and assumptions for the preliminary purchase consideration allocations may change materially.The following table sets forth the preliminary allocation of the purchase consideration to the respective fair value of assets acquired and liabilities assumed for the acquisition of Anixter:(In thousands)AssetsCash and cash equivalents$ 103,463 Trade accounts receivable 1,306,900 Other accounts receivable 116,386 Inventories 1,416,582 Prepaid expenses and other current assets 54,978 Property, buildings and equipment 211,721 Operating lease assets 280,285 Intangible assets 1,838,065 Goodwill 1,370,396 Other assets 139,760 Total assets$ 6,838,536 LiabilitiesAccounts payable$ 920,163 Accrued payroll and benefit costs 69,480 Short-term debt and current portion of long-term debt 13,225 Other current liabilities 222,119 Long-term debt 77,617 Operating lease liabilities 217,303 Deferred income taxes 374,734 Other noncurrent liabilities 245,559 Total liabilities$ 2,140,200 Fair value of net assets acquired, including goodwill and intangible assets$ 4,698,336 Table of ContentsWESCO INTERNATIONAL, INC.

For the year ended December 31, 2020, the consolidated statement of income includes $4.5 billion of net sales and $180.0 million of income from operations for Anixter. Transaction costs related to the merger were comprised of legal, advisory and other costs of  $132.2 million, which are included in selling, general and administrative expenses for the year ended December 31, 2020.Pro Forma Financial InformationThe following unaudited pro forma financial information presents combined results of operations for the periods presented, as if the Company had completed the Merger on January 1, 2019. The unaudited pro forma financial information includes adjustments to amortization and depreciation for intangible assets and property, buildings and equipment, adjustments to interest expense for the additional indebtedness incurred to complete the acquisition (including the amortization of debt discount and issuance costs), transaction costs, change in control and severance costs, dividends accrued on the Series A preferred stock, compensation expense associated with the WESCO phantom stock unit awards described in Note 14, "Employee Benefit Plans", as well as the respective income tax effects of such adjustments. For the year ended December 31, 2020, adjustments totaling $7.0 million increased the unaudited pro forma net income attributable to common stockholders, and adjustments totaling $201.3 million decreased the unaudited pro forma net income attributable to common stockholders for the year ended December 31, 2019. The unaudited pro forma financial information does not reflect any cost savings, operating synergies or revenue enhancements that WESCO may achieve as a result of its acquisition of Anixter, the costs to integrate the operations of WESCO and Anixter or the costs necessary to achieve these cost savings, operating synergies and revenue enhancements.

Headquartered in Wilmington, Massachusetts, SLS offers a full spectrum of energy-efficient lighting upgrade, retrofit, and renovation solutions with annual sales of approximately $100 million and approximately 220 employees across the U.S. and Canada. WESCO Distribution funded the purchase price paid at closing with borrowings under its then outstanding accounts receivable securitization facility. The purchase price was allocated to the respective assets and liabilities based upon their estimated fair values as of the acquisition date, resulting in goodwill of $11.6 million, which is deductible for tax purposes.Table of ContentsWESCO INTERNATIONAL, INC.

ASSETS AND LIABILITIES HELD FOR SALEOn August 6, 2020, the Company entered into a Consent Agreement with the Competition Bureau of Canada regarding the merger with Anixter. Under the Consent Agreement, the Company agreed to divest certain legacy WESCO businesses in Canada, which had total sales of approximately $120 million in 2019. Accordingly, the Company determined that the assets and liabilities of these legacy WESCO businesses in Canada met the held for sale criteria as of December 31, 2020. These businesses did not meet the criteria to be classified as discontinued operations.The assets and liabilities classified as held for sale were as follows:As ofDecember 31, 2020(In thousands) Trade accounts receivable, net$ 4,258 Inventories 16,438 Prepaid expenses and other current assets 395 Property, buildings and equipment, net 263 Operating lease assets 1,938 Intangible assets, net 5,722 Goodwill 26,059 Total assets held for sale$ 55,073 Accounts payable$ 3,639 Other current liabilities 541 Operating lease liabilities 1,537 Total liabilities held for sale$ 5,717 Table of ContentsWESCO INTERNATIONAL, INC.

The maximum borrowing limit varies by facility and ranges between $2.0 million and $31.0 million. The international lines of credit generally are renewable on an annual basis and certain facilities are fully and unconditionally guaranteed by WESCO Distribution. Accordingly, certain borrowings under these lines directly reduce availability under the Revolving Credit Facility. The applicable interest rate for borrowings under these lines of credit varies by country and is governed by the applicable loan agreement. The average interest rate for these facilities was 3.40% and 6.32% at December 31, 2020 and 2019, respectively.Accounts Receivable Securitization FacilityOn June 22, 2020, WESCO Distribution amended its accounts receivable securitization facility (the “Receivables Facility”) pursuant to the terms and conditions of a Fifth 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 amends and restates the amended and restated receivables purchase agreement entered into on September 24, 2015 (the “Existing Receivables Purchase Agreement”).The Receivables Purchase Agreement, among other things, increased the purchase limit under the Existing Receivables Purchase Agreement from $600 million to $1,025 million, with the opportunity to exercise an accordion feature that permits increases in the purchase limit of up to $375 million, extended the term of the Receivables Facility to June 22, 2023 and added and amended certain defined terms. Borrowings under the Receivables Facility bear interest at the 30-day LIBOR rate, with a LIBOR floor of 0.5%, plus applicable spreads. The interest rate spread of the Receivables Facility increased from 0.95% to 1.20%. The commitment fee remained unchanged at 0.45%.On December 14, 2020, WESCO Distribution amended its Receivables Facility pursuant to the terms and conditions of a First Amendment to the Fifth Amended and Restated Receivables Purchase Agreement (the “Receivables Amendment”). The Receivables Amendment amends the Receivables Purchase Agreement and permits an increase to the purchase limit from $1,025 million to $1,200 million. The maturity date, interest rate spread, and commitment fee of the Receivables Facility remain unchanged.Table of ContentsWESCO INTERNATIONAL, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)

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.  Since  WESCO  maintains  control  of  the  transferred  receivables,  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.  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,  2020  and  2019,  accounts  receivable  eligible  for  securitization  totaled  $1,476.1  million  and  $809.5 
million, respectively. The Consolidated Balance Sheets as of December 31, 2020 and 2019 include $950.0 million and $415.0 
million, respectively, of accounts receivable balances legally sold to third parties, as well as borrowings for equal amounts. At 
December 31, 2020, the interest rate for this facility was approximately 1.6%.

Revolving Credit Facility

On June 22, 2020, WESCO, WESCO Distribution and certain other subsidiaries of WESCO entered into a $1,100 million 
revolving credit facility (the “Revolving Credit Facility”), as a replacement of WESCO Distribution’s revolving credit facility 
entered into on September 26, 2019, pursuant to the terms and conditions of a Fourth Amended and Restated Credit Agreement, 
dated as of June 22, 2020 (the “Revolving Credit Agreement”), among WESCO Distribution, the other U.S. borrowers party 
thereto  (collectively,  the  “U.S.  Borrowers”),  WESCO  Distribution  Canada  LP  (“WESCO  Canada”),  the  other  Canadian 
borrowers party thereto (collectively, the “Canadian Borrowers”), WESCO, the lenders party thereto and Barclays Bank PLC, 
as the administrative agent. The Revolving Credit Facility contains a letter of credit sub-facility of up to $175 million and an 
accordion  feature  allowing  WESCO  Distribution  to  request  increases  to  the  borrowing  commitments  under  the  Revolving 
Credit Facility of up to $500 million in the aggregate, subject to customary conditions. The Revolving Credit Facility matures 
in June 2025.

On December 14, 2020, WESCO Distribution and certain other subsidiaries of WESCO entered into an amendment to the 
Revolving Credit Facility pursuant to the terms and conditions of a First Amendment to Fourth Amended and Restated Credit 
Agreement,  dated  as  of  December  14,  2020  (the  “Revolver  Amendment”),  among  WESCO  Distribution,  the  other  U.S. 
borrowers  party  thereto,  WESCO  Distribution  Canada  LP,  the  other  Canadian  borrowers  party  thereto,  WESCO,  the  lenders 
party thereto and Barclays Bank PLC, as administrative agent. The Revolver Amendment permits an increase to the revolving 
commitments  from  $1,100  million  to  $1,200  million  and  amends  certain  other  defined  terms.  No  other  material  terms  were 
changed.

The  obligations  of  WESCO  Distribution  and  the  other  U.S.  Borrowers  under  the  Revolving  Credit  Facility  have  been 
guaranteed  by  WESCO  and  certain  of  WESCO  Distribution’s  subsidiaries  (including  certain  subsidiaries  of  Anixter).  The 
obligations  of  WESCO  Canada  and  the  other  Canadian  Borrowers  under  the  Revolving  Credit  Facility  (including  certain 
subsidiaries of Anixter) have been guaranteed by certain subsidiaries of WESCO Canada and the other Canadian Borrowers. 
The Revolving Credit Facility is secured by (i) substantially all assets of WESCO Distribution, the other U.S. Borrowers and 
certain of WESCO Distribution’s subsidiaries (including certain subsidiaries of Anixter), other than, among other things, real 
property and accounts receivable sold or intended to be sold pursuant to WESCO Distribution’s Receivables Facility, and (ii) 
substantially all assets of WESCO Canada, the other Canadian Borrowers and certain of WESCO Canada’s subsidiaries, other 
than, among other things, real property, in each case, subject to customary exceptions and limitations. 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  1.50%  for  LIBOR-based  borrowings  and  0.25%  and  0.50%  for  prime  rate-based  borrowings.  At 
December 31, 2020, the interest rate for this facility was approximately 1.6%.

The Revolving Credit Agreement requires compliance with conditions that must be satisfied prior to any borrowing as well 
as ongoing compliance with certain customary affirmative and negative covenants. The Revolving Credit Agreement contains 
customary events of default. Upon the occurrence and during the continuance of an event of default, the commitments of the 
lenders  may  be  terminated,  and  all  outstanding  obligations  of  the  loan  parties  under  the  Revolving  Credit  Facility  may  be 
declared immediately due and payable.

During 2020, WESCO borrowed $1,197.9 million under the prior and new revolving credit facilities and made repayments 
in  the  aggregate  amount  of  $948.0  million.  During  2019,  aggregate  borrowings  and  repayments  under  prior  revolving  credit 
agreements were $715.4 million and $767.4 million, respectively. WESCO had $801.5 million available under the Revolving 
Credit facility at December 31, 2020, after giving effect to $48.5 million of outstanding letters of credit, as compared to $563.8 
million  available  under  the  prior  revolving  credit  facility  at  December  31,  2019,  after  giving  effect  to  $28.4  million  of 
outstanding letters of credit, $36.1 million of surety bonds, and $7.8 million of other reserves.

6.00% Senior Notes due 2025

On April 30, 2020, in connection with the Merger, WESCO Distribution commenced offers to purchase for cash (each, a 
“WESCO Tender Offer” and, together the “WESCO Tender Offers”) any and all of Anixter Inc.’s outstanding (i) 5.50% Senior

Indentures”) by and among Anixter Inc., Anixter and Wells Fargo Bank, National Association, as trustee.

Concurrent  with  the  WESCO  Tender  Offers,  Anixter  Inc.  commenced  consent  solicitations  to  amend  the  definition  of 
"Change  of  Control"  under  the  applicable  Indenture  to  exclude  the  Merger  and  related  transactions  and  expressly  permit  a 
merger between Anixter Inc. and Anixter (the “Anixter Consent Solicitations”).

On June 23, 2020 (the "Expiration Date"), following the completion of the Merger, the WESCO Tender Offers and Anixter 
Consent Solicitations expired and settled. Pursuant to the terms of the Offer to Purchase and Consent Solicitation Statement, 
dated April 30, 2020, holders of the Anixter Senior Notes that validly tendered and did not validly withdraw prior to such date, 
received total tender offer consideration of $1,012.50 per $1,000 principal amount of Anixter Senior Notes, which amount, in 
each  case,  included  an  early  tender  payment  of  $50.00  per  $1,000  principal  amount  of  Anixter  Senior  Notes.  Holders  who 
validly delivered their consents at or prior to the Expiration Date received a consent fee of $2.50 per $1,000 principal amount of

and, together with the 2025 Notes, the “Notes”). The 2025 Notes were issued at a price of 100.000% of the aggregate principal 
amount. The 2028 Notes were issued at a price of 99.244% of the aggregate principal amount. WESCO incurred costs related to 
the issuance of the 2025 Notes and 2028 Notes totaling $33.1 million and $29.3 million, respectively, which were recorded as a 
reduction to the carrying value of the debt and are being amortized over the respective lives of the notes.

The Notes were issued pursuant to, and are governed by, an indenture (the “Notes Indenture”), dated as of June 12, 2020, 
between  the  Company,  WESCO  Distribution  and  U.S.  Bank  National  Association,  as  trustee  (the  “Trustee”).  The  Notes  and

Act”) and have not been, and will not be, registered under the Securities Act and may not be offered or sold in the U.S. absent 
registration or an applicable exemption from, or in a transaction not subject to the registration requirements of the Securities 
Act and other applicable securities laws.

The Company used the net proceeds from the issuance of the Notes, together with borrowings under its new and amended 
credit  facilities  and  existing  cash  on  hand,  to  finance  the  Merger  and  the  other  transactions  contemplated  by  the  Merger 
Agreement. The use of proceeds included (i) paying the cash portion of the Merger consideration to stockholders of Anixter, (ii) 
refinancing  certain  existing  indebtedness  of  Anixter  contemplated  by  the  Merger  Agreement,  including  financing  the 
satisfaction and discharge, defeasance, redemption or other repayment in full of the 5.125% Senior Notes due 2021 of Anixter 
Inc., a wholly owned subsidiary of Anixter, and financing payments in connection with the Anixter Consent Solicitations and 
WESCO Tender Offers, as described above, (iii) refinancing other indebtedness of the Company, and (iv) paying fees, costs and 
expenses in connection with the foregoing.

The  Notes  are  unsecured  and  unsubordinated  obligations  of  WESCO  Distribution  and  are  guaranteed  on  an  unsecured, 
unsubordinated basis by the Company and Anixter Inc. The 2025 Notes accrue interest at a rate of 7.125% per annum, payable

WESCO Distribution may redeem all or a part of the 2025 Notes at any time prior to June 15, 2022 by paying a “make-whole” premium plus accrued and unpaid interest, if any, to but excluding the redemption date. In addition, at any time prior to June 15, 2022, WESCO Distribution may redeem up to 35% of the 2025 Notes with the net cash proceeds from certain equity offerings. On or after June 15, 2022, WESCO Distribution may redeem all or a part of the 2025 Notes on the redemption dates and at the redemption prices specified in the Notes Indenture. WESCO Distribution may redeem all or a part of the 2028 Notes at any time prior to June 15, 2023 by paying a “make-whole” premium plus accrued and unpaid interest, if any, to but excluding the redemption date. In addition, at any time prior to June 15, 2023, WESCO Distribution may redeem up to 35% of the 2028 Notes with the net cash proceeds from certain equity offerings. On or after June 15, 2023, WESCO Distribution may redeem all or a part of the 2028 Notes on the redemption dates and at the redemption prices specified in the Notes Indenture.The Notes Indenture contains certain covenants that, among other things, limit (i) the Company’s and its subsidiaries’ ability to pay dividends on or repurchase the Company’s capital stock, incur liens on assets, engage in certain sale and leaseback transactions or sell certain assets, and (ii) the Company’s and any guarantor’s ability to sell all or substantially all of its assets to, or merge or consolidate with or into, other persons, in the case of each of the foregoing, subject to certain qualifications and exceptions, including the termination of certain of these covenants upon the Notes receiving investment grade credit ratings.The Notes Indenture contains certain events of default, including, among other things, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay or acceleration of certain other indebtedness, certain events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the Notes Indenture will allow either the Trustee or the holders of at least 25% in aggregate principal amount of the applicable series of the then-outstanding Notes to accelerate, or in certain cases, will automatically cause the acceleration of the amounts due under the applicable series of Notes.Debt Issuance CostsWESCO 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. As of December 31, 2020 and 2019, unamortized debt issuance costs of $78.9 million and $8.9 million were recorded in the Consolidated Balance Sheets, respectively.Covenant ComplianceWESCO was in compliance with all relevant covenants contained in its debt agreements as of December 31, 2020.The following table sets forth the aggregate principal repayment requirements for all indebtedness for the next five years and thereafter, as of December 31, 2020:(In thousands)2021$ 529,869 2022 4,051 2023 1,016,322 2024 352,183 2025 1,756,055 Thereafter 1,326,835 Total payments on debt$ 4,985,315 Debt discount (9,332) Total debt$ 4,975,983 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.

11. STOCKHOLDERS' EQUITY

Preferred Stock

There are 20 million shares of preferred stock authorized at a par value of $0.01 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.

Series A Preferred Stock

The Company's Board of Directors authorized 25,000 shares of fixed-rate reset cumulative perpetual preferred stock, Series 
A,  with  a  liquidation  preference  of  $25,000  per  whole  preferred  share  and  a  par  value  of  $0.01  per  share  (the  "Series  A 
Preferred Stock"). Depositary shares, each representing a 1/1,000th interest in a share of Series A Preferred Stock, are registered 
under the Securities Act of 1933, as amended.

In connection with the Merger, as described in Note 6, "Acquisitions", the Company issued 21,611,534 depositary shares, 

representing an interest in approximately 21,612 shares of Series A Preferred Stock.

Holders of shares of the Series A Preferred Stock are entitled to receive, when, as and if declared by the Company's Board 
of Directors, cumulative cash dividends at an initial rate of 10.625% per annum of the $25,000 liquidation preference per share. 
On June 22, 2025, and every five-year period thereafter, the dividend rate on the Series A Preferred Stock resets and will be 
equal to the Five-year U.S. Treasury Rate plus a spread of 10.325%.

Holders of the Series A Preferred Stock are not entitled to convert or exchange their shares of Series A Preferred stock into 
shares of any of WESCO’s other classes or series of stock or into any other security of WESCO (other than upon a change of 
control  involving  the  issuance  of  additional  shares  of  common  stock  or  other  change  of  control  transaction,  in  each  case, 
approved by holders of common stock).

The Series A Preferred Stock has no stated maturity and will not be subject to any sinking fund, retirement fund or purchase 

fund or any other obligation of WESCO to redeem, repurchase or retire the Series A Preferred Stock.

Holders  of  the  Series  A  Preferred  Stock  will  have  limited  voting  rights,  including  the  right  to  elect  two  directors  to  the 
board of directors of the Company in the event dividends on the Series A Preferred Stock remain unpaid for the equivalent of 
six or more full quarterly dividend periods.

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 
$0.01  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, as well as the indentures governing the 2021 Notes, 2024 Notes, 2025 Notes 
and 2028 Notes, place certain limits on the Company's ability to declare or pay dividends and repurchase common stock. The 
share repurchases in 2019 and 2018, as described in Note 13, "Earnings Per Share", were made within the limits of WESCO's 
various  credit  agreements.  At  December  31,  2020  and  2019,  no  dividends  had  been  declared  and,  therefore,  no  retained 
earnings were reserved for dividend payments.

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.

Stockholder Rights PlanOn July 17, 2020, WESCO's Board of Directors declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of common stock of WESCO, par value $0.01 per share (“WESCO Common Stock”), and adopted a stockholder rights plan, as set forth in the Rights Agreement, dated as of July 17, 2020 (the “Rights Agreement”), by and between WESCO and Computershare Trust Company, N.A., as rights agent. In general terms, the Rights Agreement works by imposing a significant penalty upon any person or group which acquires 10% or more (15% or more in the case of passive investors filing statements on Schedule 13G) of the outstanding WESCO Common Stock without the approval of the Board. The dividend Right was paid on July 27, 2020 to WESCO stockholders of record as of the close of business on July 27, 2020. The Rights Agreement provides that the Rights will expire on July 16, 2021. The Rights have no value upon issuance.12. INCOME TAXESPursuant to the enactment of the Tax Cuts and Jobs Act of 2017 (the "TCJA”) on December 22, 2017, the Company recognized the provisional income tax effects of the TCJA in the year ended December 31, 2017. During the year ended December 31, 2018, the Company completed its accounting for the income tax effects of the TCJA, which resulted in an additional deferred income tax benefit of $0.9 million and a discrete benefit of $3.4 million. During the year ended December 31, 2019, the Company further adjusted its liability for the one-time tax on the deemed repatriation of undistributed foreign earnings (the "transition tax") based upon guidance issued by the Internal Revenue Service ("IRS"), which resulted in a discrete benefit of $3.7 million. As of December 31, 2020 and 2019, a liability of $63.3 million and $36.8 million, respectively, was recorded as components of other current and noncurrent liabilities in the Consolidated Balance Sheets for the transition tax. The transition tax will be paid in installments.The accounting for the income tax effects of the TCJA is complete based on regulatory guidance issued to date. Additional guidance could be issued, which could affect the amounts described above. The Company will continue to evaluate its tax positions with respect to the TCJA as the IRS releases additional regulatory guidance. Future adjustments, if any, for tax positions taken to date will be recognized as discrete income tax expense or benefit in the period in which such guidance is issued.The following table sets forth the components of income before income taxes by jurisdiction: Year Ended December 31, 202020192018  (In thousands) United States$ 26,031 $ 198,566 $ 198,556 Foreign 96,811  83,495  82,469    Income before income taxes$ 122,842 $ 282,061 $ 281,025 The following table sets forth the components of the provision (benefit) for income taxes: Year Ended December 31, 202020192018  (In thousands) Current income taxes:     Federal$ 25,605 $ 31,695 $ 28,464 State 11,322  8,616  7,458 Foreign 19,414  6,347  10,611 Total current income taxes 56,341  46,658  46,533 Deferred income taxes:   Federal (17,913)  6,774  5,253 State (7,264)  1,846  1,967 Foreign (8,361)  4,585  1,917 Total deferred income taxes (33,538)  13,205  9,137  Provision for income taxes$ 22,803 $ 59,863 $ 55,670 Table of ContentsWESCO INTERNATIONAL, INC.

Most of these earnings have been taxed in the U.S. under either the one-time transition tax or the GILTI tax regime imposed by the TCJA. Except for a portion of foreign earnings previously taxed in the U.S. that can effectively be distributed without further material U.S. or foreign taxation, the Company continues to assert that the undistributed earnings of its foreign subsidiaries are indefinitely reinvested. To the extent the earnings of the Company's foreign subsidiaries are distributed in the form of dividends, such earnings may be subject to additional taxes. WESCO estimates that additional taxes of approximately $75.0 million would be payable upon the remittance of foreign earnings as dividends at December 31, 2020, based upon the laws in effect on that date. The Company believes that it is able to maintain a sufficient level of liquidity for its domestic operations and commitments without incurring any material tax cost to repatriate cash held by its foreign subsidiaries.The following table sets forth deferred tax assets and liabilities: As of December 31, 20202019  (In thousands)  AssetsLiabilitiesAssetsLiabilitiesAccounts receivable$ 17,560 $ — $ 3,382 $ — Inventories 14,793  —  —  4,580 Depreciation of property, buildings and equipment —  60,687  —  18,393 Operating leases 134,377  136,477  61,326  60,670 Amortization of intangible assets —  540,520  —  159,573 Employee benefits 53,040  —  20,641  — Stock-based compensation 14,061  —  13,792  — Tax loss carryforwards 36,923  —  10,486  — Foreign tax credit carryforwards 55,637  —  1,247  — Other 27,643  6,286  6,791  3,964 Deferred income taxes before valuation allowance 354,034  743,970  117,665  247,180 Valuation allowance (60,629)  —  (5,854)  — Total deferred income taxes$ 293,405 $ 743,970 $ 111,811 $ 247,180 In connection with the acquisition of Anixter, WESCO recorded deferred income tax liabilities of $347.3 million, which  primarily related to identifiable intangible assets for which there was no increase in tax basis.Table of ContentsWESCO INTERNATIONAL, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)75WESCO had deferred tax assets of $34.5 million and $7.9 million as of December 31, 2020 and 2019, respectively, related to foreign net operating loss carryforwards. These net operating loss carryforwards expire beginning in 2021 through 2030, while some may be carried forward indefinitely.  The Company determined that certain foreign net operating loss carryforwards would not be realized before they expire. Accordingly, the Company recorded a valuation allowance of $22.3 million and $4.6 million against deferred tax assets related to certain foreign net operating loss carryforwards at December 31, 2020 and 2019, respectively. Additionally, these foreign jurisdictions had deferred tax assets of $8.2 million as of December 31, 2020 related to other future deductible temporary differences. The Company recorded a full valuation allowance against this amount as of December 31, 2020. As of December 31, 2020 and 2019, WESCO had deferred tax assets of $2.4 million and $2.6 million, respectively, related to state net operating loss carryforwards. These carryforwards expire beginning in 2024 through 2039.As of December 31, 2020 and 2019, WESCO had deferred tax assets of $55.6 million and $1.2 million, respectively, related to foreign tax credit carryforwards. The foreign tax credit carryforwards expire beginning in 2026 through 2030. The Company determined that certain foreign tax credit carryforwards will not be realized before they expire. Accordingly, the Company recorded a valuation allowance of $30.1 million and  $1.2 million against deferred tax assets related to certain foreign tax credit carryforwards at December 31, 2020 and 2019, respectively.The Company is under examination by tax authorities in various jurisdictions and remains subject to examination until the applicable statutes of limitation expire.

The amount of unrecognized tax benefits that would affect the effective tax rate if recognized in the consolidated financial statements for the years ended December 31, 2020, 2019 and 2018 were $29.1 million, $0.1 million, and $1.3 million, respectively. Within the next twelve months, the amount of unrecognized tax benefits is expected to decrease by $3.6 million due to the expiration of statutes of limitation. Such change would result in a favorable effective tax rate impact of $4.2 million.The Company classifies interest related to unrecognized tax benefits as a component of net interest in the Consolidated Statement of Income and Comprehensive Income. In 2020, the Company recognized interest expense on unrecognized tax benefits of $0.3 million. The Company recognized interest income on unrecognized tax benefits of $0.8 million in 2019. In 2018, interest expense on unrecognized tax benefits was $0.2 million. As of December 31, 2020 and 2019, WESCO had a liability of $5.5 million and $0.1 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 for 2020, 2019, and 2018 were immaterial. As of December 31, 2020, WESCO had a liability of $1.5 million for penalties related to unrecognized tax benefits.Table of ContentsWESCO INTERNATIONAL, INC.

EARNINGS PER SHAREBasic earnings per share is computed by dividing net income attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Diluted earnings per share is computed by dividing net income attributable to common stockholders 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.The following table sets forth the details of basic and diluted earnings per share: Year Ended December 31, 202020192018(In thousands, except per share data)  Net income attributable to WESCO International, Inc.$ 100,560 $ 223,426 $ 227,343 Less: Preferred stock dividends 30,139  —  — Net income attributable to common stockholders$ 70,421 $ 223,426 $ 227,343 Weighted-average common shares outstanding used in computing basic earnings per share 46,174  43,104  46,722 Common shares issuable upon exercise of dilutive equity awards 451  383  477 Weighted-average common shares outstanding and common share equivalents used in computing diluted earnings per share 46,625  43,487  47,199 Earnings per share attributable to common stockholders Basic$ 1.53 $ 5.18 $ 4.87 Diluted$ 1.51 $ 5.14 $ 4.82 For the years ended December 31, 2020, 2019 and 2018, the computation of diluted earnings per share attributable to common stockholders excluded equity awards of approximately 1.8 million, 1.7 million and 1.6 million, respectively. These shares were excluded because their effect would have been antidilutive.In December 2017, the Company's Board of Directors (the "Board") authorized the repurchase of up to $300 million of the Company's common stock through December 31, 2020 (the "Repurchase Authorization"). In October 2018, the Board approved an increase to the Repurchase Authorization from $300 million to $400 million. During the year ended December 31, 2018, the Company entered into accelerated stock repurchase agreements with a financial institution to repurchase shares of its common stock pursuant to its Repurchase Authorization. In exchange for up-front cash payments totaling $125.0 million, the Company received 2,368,738 shares, of which 365,272 shares were settled in 2019.On May 7, 2019, the Company entered into an accelerated stock repurchase agreement with a financial institution to repurchase additional shares of its common stock pursuant to the Repurchase Authorization. In exchange for an up-front cash payment of $150.0 million, the Company received 3,090,312 shares. The Company did not repurchase any shares of its common stock during the year ended December 31, 2020. As of December 31, 2020, WESCO had repurchased 5,459,030 shares of common stock for $275.0 million under the Repurchase Authorization.The total number of shares ultimately delivered under the accelerated stock repurchase transactions described above were determined by the average of the volume-weighted-average price of the Company's common stock for each exchange business day during the respective settlement valuation periods. WESCO funded the repurchases with available cash, and borrowings under its accounts receivable securitization and revolving credit facilities. For purposes of computing earnings per share, share repurchases have been reflected as a reduction to common shares outstanding on the respective delivery dates.

14. EMPLOYEE BENEFIT PLANS  

Defined Contribution Plans

WESCO Distribution sponsors a defined contribution retirement savings plan for the majority of its U.S. employees. The 
Company matches contributions made by employees at an amount equal to 50% of participants' total monthly contributions up 
to 6% of eligible compensation. Contributions are made in cash and employees have the option to transfer balances allocated to 
their accounts into any of the available investment options. Due to the COVID-19 pandemic and its adverse effect on WESCO's 
results  of  operations,  the  Company  suspended  matching  employer  contributions  between  April  16,  2020  and  September  30, 
2020. The Company may also make, subject to the Board's approval, a discretionary contribution to the defined contribution 
levels  are  attained.  There 
retirement  savings  plan  covering  U.S.  participants 
were no discretionary contributions for the years ended December 31, 2020 and December 31, 2019. Discretionary employer 
contribution charges of $20.6 million were incurred in 2018.

WESCO  Distribution  Canada  LP,  a  wholly-owned  subsidiary  of  the  Company,  sponsors  a  defined  contribution  plan  for 
certain  Canadian  employees.  The  Company  makes  contributions  in  amounts  ranging  from  3%  to  5%  of  participants'  eligible 
compensation based on years of continuous service.

Anixter  Inc.  sponsors  a  defined  contribution  plan  covering  all  of  its  non-union  U.S.  employees  (the  "Anixter  Employee 
Savings Plan"). The employer match for the Anixter Employee Savings Plan is equal to 50% of a participant's contribution up 
to 5% of the participant's compensation. Anixter Inc. will also make an annual contribution to the Anixter Employee Savings 
Plan on behalf of each active participant who is hired or rehired on or after July 1, 2015, or is not participating in the Anixter 
Inc.  Pension  Plan.  The  amount  of  the  employer  annual  contribution  is  equal  to  either  2%  or  2.5%  of  the  participant’s 
compensation, as determined by the participant’s years of service. This contribution is in lieu of being eligible for the Anixter 
Inc.  Pension  Plan.  Certain  of  Anixter  Inc.'s  foreign  subsidiaries  also  have  defined  contribution  plans.  Contributions  to  these 
plans are based upon various levels of employee participation and legal requirements.

For  the  years  ended  December  31,  2020,  2019  and  2018,  WESCO  incurred  charges  of  $18.3  million,  $22.9  million,  and 

$42.9 million, respectively, for all defined contribution plans.

Deferred Compensation Plans

WESCO  Distribution  sponsors  a  non-qualified  deferred  compensation  plan  (the  "WESCO  Deferred  Compensation  Plan") 
that  permits  select  employees  to  make  pre-tax  deferrals  of  salary  and  bonus.  Employees  have  the  option  to  transfer  balances 
allocated  to  their  accounts  in  the  WESCO  Deferred  Compensation  Plan  into  any  of  the  available  investment  options.  The 
WESCO  Deferred  Compensation  Plan  is  an  unfunded  plan.  As  of  December  31,  2020,  the  Company's  obligation  under  the 
deferred  compensation  plan  was  $27.4  million,  of  which  $10.1  million  was  included  in  other  current  liabilities  and  $17.3 
million  in  other  noncurrent  liabilities  in  the  Consolidated  Balance  Sheet.  At  December  31,  2019,  the  Company's  obligation 
under the deferred compensation plan was $25.2 million and was included in other noncurrent liabilities in the Consolidated 
Balance Sheet.

Anixter Inc. sponsors a non-qualified deferred compensation plan (the "Anixter Deferred Compensation Plan")  that permits 
select  employees  to  make  pre-tax  deferrals  of  salary  and  bonus.  Interest  is  accrued  monthly  on  the  deferred  compensation 
balances based on the average ten-year Treasury note rate for the previous three months times a factor of 1.4, and the rate is 
further  adjusted  if  certain  financial  goals  are  achieved.  In  the  fourth  quarter  of  2020,  the  Company  made  a  determination  to 
terminate the Anixter Deferred Compensation Plan. Accordingly, a deferred compensation liability of $45.1 million has been 
classified in other current liabilities in the Consolidated Balance Sheet at December 31, 2020 as the Company expects to make 
lump sum payments directly to participants of the plan during 2021.

Concurrent  with  the  implementation  of  the  Anixter  Deferred  Compensation  Plan,  Anixter  established  a  Rabbi  Trust 
arrangement to provide for the liabilities associated with the deferred compensation plan and an executive non-qualified defined 
benefit  plan.  The  assets  are  invested  in  marketable  securities.  At  December  31,  2020,  $39.6  million  was  recorded  in  other 
current assets in the Consolidated Balance Sheet for this arrangement.

Defined Benefit Plans

 WESCO sponsors a contributory defined benefit plan (the "EECOL Plan") covering substantially all Canadian employees 
of EECOL. The EECOL Plan provides retirement benefits based on earnings and credited service, and participants contribute 
2% of their earnings to the EECOL Plan. Participants become 100% vested after two years of continuous service or, if earlier, at 
the participant's normal retirement age.

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

WESCO also sponsors a Supplemental Executive Retirement Plan (the "EECOL SERP"), which provides additional pension 
benefits to certain executives of EECOL based on earnings, and credited service. Effective January 1, 2013, the EECOL SERP 
was closed to new participants and existing participants became 100% vested. EECOL SERP participants continue to contribute 
4% of their earnings to the EECOL Plan.

In  connection  with  the  June  22,  2020  acquisition  of  Anixter  discussed  in  Note  6,  "Acquisitions",  the  Company  assumed 
various defined benefit pension plans sponsored by Anixter Inc. These include defined benefit pension plans in the U.S., which 
consist  of  the  Anixter  Inc.  Pension  Plan,  the  Executive  Benefit  Plan  and  the  Supplemental  Executive  Retirement  Plan  (the 
"Anixter  SERP")  (together,  the  "Domestic  Plans")  and  various  defined  benefit  pension  plans  covering  employees  of  foreign 
subsidiaries in Canada and Europe (together with the "EECOL Plan" and "EECOL SERP", the "Foreign Plans"). For all defined 
benefit plans assumed as part of the merger with Anixter, the projected benefit obligation ("PBO") and fair value of plan assets 
were remeasured as of the acquisition date.

The  Anixter  Inc.  Pension  Plan  was  frozen  to  entrants  first  hired  or  rehired  on  or  after  July  1,  2015.  The  majority  of  the 
Anixter defined benefit pension plans are non-contributory and, with the exception of the U.S. and Canada, cover substantially 
all full-time employees in their respective countries. Retirement benefits are provided based on compensation as defined in each 
of the pension plans.

In the fourth quarter of 2020, the Company made a determination to terminate both the Anixter Inc. Executive Benefit Plan 
and the Anixter SERP. Accordingly, pension liabilities totaling $18.1 million associated with the Anixter Inc. Executive Benefit 
Plan  and  the  Anixter  SERP  have  been  classified  as  current  on  the  Consolidated  Balance  Sheet  at  December  31,  2020  as  the 
Company expects to make lump sum payments directly to participants of these plans during 2021.

The Domestic Plans are funded as required by the Employee Retirement Income Security Act of 1974 ("ERISA") and the 
IRS and all Foreign Plans, including the EECOL Plan and EECOL SERP, are funded as required by applicable foreign laws. 
The Anixter Inc. Executive Benefit Plan and the Anixter SERP are unfunded plans.

AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)80The measurement date for all plans is December 31st. Accordingly, at the end of each fiscal year, the Company determines the discount rate to measure the plan liabilities at their present value. The discount rate reflects the current rate at which the pension liabilities could effectively be settled at the end of the year. In estimating this rate at the end of 2020, the Company reviewed rates of return on relevant market indices and concluded the Willis Towers Watson Global Rate Link Model was consistent with observable market conditions and industry standards for developing spot rate curves. At the end of 2019, the discount rate related to the EECOL Plan and the EECOL SERP was determined using the Canadian Institute of Actuaries methodology.At December 31, 2020 and 2019, the consolidated weighted-average discount rate of all plans was 2.2% and 3.2%, respectively, and these rates were used to measure the PBO at the end of each respective year end. Due primarily to the merger with Anixter, the PBO increased to $819.3 million at December 31, 2020 from $134.9 million at December 31, 2019. The consolidated net unfunded status was $98.3 million at December 31, 2020 compared to $31.5 million at December 31, 2019.The PBO in 2020 was $332.5 million for the Domestic Plans and $486.8 million for the Foreign Plans. The Company had 13 plans in 2020 where the PBO was in excess of the fair value of plan assets. For pension plans with PBO in excess of plan assets the aggregate PBO was $504.8 million, and the aggregate fair value of plan assets was $365.4 million. The PBO in 2019 of $134.9 million related to the EECOL Plan and the EECOL SERP and compared to a fair value of plan assets of $103.4 million.The accumulated benefit obligation in 2020 was $328.2 million for the Domestic Plans and $417.6 million for the Foreign Plans. The Company had 13 plans in 2020 where the accumulated benefit obligation was in excess of the fair value of plan assets. For pension plans with accumulated benefit obligations in excess of plan assets the aggregate pension accumulated benefit obligation was $435.6 million, and the aggregate fair value of plan assets was $365.4 million. The accumulated benefit obligation in 2019 of $104.6 million related to the EECOL Plan and the EECOL SERP and compared to a fair value of plan assets of $103.4 million.The following table presents the components of net periodic pension (benefit) cost:Domestic Plans(1)Foreign Plans(1)Total(In thousands)202020192018202020192018202020192018Components of Net Periodic Pension (Benefit) Cost Service cost$ 1,763 $ — $ — $ 9,029 $ 4,602 $ 5,242 $ 10,792 $ 4,602 $ 5,242 Interest cost 4,787  —  —  7,162  4,362  4,137  11,949  4,362  4,137 Expected return on plan assets (8,395)  —  —  (11,659)  (5,695)  (5,969)  (20,054)  (5,695)  (5,969) Recognized actuarial gain —  —  —  —  (63)  (46)  —  (63)  (46) Settlement —  —  —  (144)  —  —  (144)  —  — Net periodic pension (benefit) cost$ (1,845) $ — $ — $ 4,388 $ 3,206 $ 3,364 $ 2,543 $ 3,206 $ 3,364 (1)  As described above, the Company assumed the Domestic Plans and certain foreign plans in connection with the June 22, 2020 acquisition of Anixter. The Company began recognizing the associated net periodic pension (benefit) cost as of the acquisition date.The service cost of $10.8 million, $4.6 million and $5.2 million for the years ended December 31, 2020, 2019 and 2018, respectively, was reported as a component of selling, general and administrative expenses. The other components of net periodic pension (benefit) cost totaling a net benefit of $8.2 million, $1.4 million and $1.9 million for the years ended December 31, 2020, 2019 and 2018, respectively, were presented as a component of other, net.The following weighted-average actuarial assumptions were used to determine net periodic pension (benefit) cost:Domestic Plans(1)Foreign Plans(1)Total202020192018202020192018202020192018Discount rate 2.9 % — % — % 2.2 % 4.0 % 3.5 % 2.5 % 4.0 % 3.5 %Expected return on plan assets 5.5 % — % — % 5.2 % 6.4 % 6.4 % 5.3 % 6.4 % 6.4 %Rate of compensation increase 3.8 % — % — % 3.4 % 3.8 % 3.8 % 3.5 % 3.8 % 3.8 %(1)  As described above, the Company assumed the Domestic Plans and certain foreign plans in connection with the June 22, 2020 acquisition of Anixter. The Company began using the related assumptions as of the acquisition date.Table of ContentsWESCO INTERNATIONAL, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)81The expected long-term rate of return on plan assets reflects the average rate of earnings expected on the invested assets and future assets to be invested to provide for the benefits included in the projected benefit obligation. The Company uses historic plan asset returns combined with current market conditions to estimate the rate of return. The weighted-average expected long-term rate of return on plan assets used in the determination of net periodic pension cost for 2020 was 5.3%. As a result of the combined effect of valuation changes in both the equity and bond markets, the plan assets produced an actual gain of 13.6% in 2020. The difference between the expected return and actual return on plan assets is amortized into expense over the service lives of the plan participants. These amounts are reflected on the balance sheet through charges to accumulated other comprehensive loss, a component of stockholders’ equity.The following table sets forth the changes and the end of year components of accumulated other comprehensive (income) loss for the defined benefit plans:Year Ended December 31,(In thousands)20202019Changes to Balance: Beginning balance, before tax effect$ 8,890 $ (2,696) Prior service credit arising in current year (37)  — Net actuarial (gain) loss arising in current year (12,154)  11,586 Curtailment (101)  — Settlement 144  — Foreign currency exchange rate changes 196  — Ending balance, before tax effect$ (3,062) $ 8,890 As of December 31,(In thousands)20202019Components of Balance:Prior service credit$ (37) $ — Net actuarial (gain) loss (3,025)  8,890 Ending balance, before tax effect (3,062)  8,890 Tax effect 562  (2,329) Ending balance, after tax effect$ (2,500) $ 6,561 The following benefit payments, which reflect expected future service, are expected to be paid as follows:(In thousands)Domestic PlansForeign PlansTotal2021$ 28,527 $ 9,873 $ 38,400 2022 11,165  9,978  21,143 2023 12,065  10,613  22,678 2024 13,046  11,145  24,191 2025 13,807  11,988  25,795 2026 to 2030 78,122  83,178  161,300 The Company expects to contribute approximately $11.4 million to its Foreign Plans in 2021. The Company does not expect to make a contribution to its domestic qualified pension plan in 2021 due to its overfunded status. As a result of the termination of its two domestic non-qualified pension plans, the Company estimates that it will make $18.1 million of lump sum payments directly to participants of these plans during 2021.The assets of the various defined benefit plans are held in separate independent trusts and managed by independent third party advisors. The investment objective for the defined benefit plans is to ensure an adequate level of assets is available to fund the benefits owed to employees and their beneficiaries when they become payable. In meeting this objective, the Company seeks to achieve a level of absolute investment return consistent with a prudent level of portfolio risk. The Company's risk preference is to refrain from exposing the plans to higher volatility in pursuit of potential higher returns.Table of ContentsWESCO INTERNATIONAL, INC.

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

The  pension  committees  meet  regularly  to  assess  investment  performance  relative  to  asset  allocation  guidelines.  The 

Company periodically rebalances its asset portfolios to be in line with its allocation guidelines.

For 2020, the Domestic plan investment policy guidelines were as follows:
•
•
•
•
• Derivative instruments such as futures, swaps and options may be used on a limited basis;  For funds that employ 

Each asset class is managed by one or more active and passive investment managers
Each asset class may be invested in a commingled fund, mutual fund, or separately managed account
Investment in Exchange Traded Funds ("ETFs") is permissible
Each manager is expected to be "fully invested" with minimal cash holdings

•
•
•

derivatives, the loss of invested capital to the Trust should be limited to the amount invested in the fund
The equity portfolio is diversified by sector and geography
The real assets portfolio is invested in Real Estate Investment Trusts ("REITs") and private real estate
The fixed income is invested in U.S. Treasuries, investment grade corporate debt (denominated in U.S. dollars), and 
other credit investments including below investment grade rated bonds and loans, securitized credit, and emerging 
market debt

The investment policies for the Foreign plans are the responsibility of the various trustees. Generally, the investment policy 

guidelines are as follows:

• Make sure that the obligations to the beneficiaries of the plan can be met
• Maintain funds at a level to meet the minimum funding requirements
•

The investment managers are expected to provide a return, within certain tracking tolerances, close to that of the 
relevant market’s indices

The amounts presented in the table are intended to reconcile the fair value hierarchy to the total fair value of plan assets.The Domestic and Foreign Plans' 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. 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 net asset value (NAV) per share practical expedient are not classified in the fair value hierarchy. The majority of pension assets are comprised of common/collective/pool funds (i.e., mutual funds). These funds 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.Other BenefitsAs permitted by the Merger Agreement, Anixter granted restricted stock units prior to June 22, 2020 in the ordinary course of business to its employees. These awards, which did not accelerate solely as a result of the Merger, were converted into cash-only settled WESCO phantom stock units, which vest ratably over a 3-year period. As of December 31, 2020, the estimated fair value of these awards was $22.8 million. The Company recognized compensation expense associated with these awards of $9.2 million for the year ended December 31, 2020, which is reported as a component of selling, general and administrative expenses.15. STOCK-BASED COMPENSATIONWESCO sponsors a stock-based compensation plan. The 1999 Long-Term Incentive Plan, as amended and restated (the “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 is administered by the Compensation Committee of the Board.On May 31, 2017, the Company renewed and restated the LTIP, increasing the maximum number of shares of common stock that may be issued under the plan by 1.7 million shares to 3.4 million. In connection with the merger with Anixter on June 22, 2020, the Company assumed a portion of the remaining share reserve available under Anixter’s 2017 Stock Incentive Plan. The number of assumed shares, as adjusted, was equal to 185,000 shares and may be used for awards to be granted under the LTIP. Under the LTIP, the total number of shares of common stock authorized to be issued will be reduced by 1 share of common stock for every 1 share that is subject to a stock appreciation right granted, and 1.83 shares of common stock for every 1 share that is subject to an award other than a stock appreciation right granted on or after May 31, 2017. As of December 31, 2020, 1.1 million shares of common stock were reserved under the LTIP for future equity award grants.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 estimated forfeitures, over the service period for awards expected to vest. The fair value of stock-settled stock appreciation rights is determined using the Black-Scholes model. The fair value of restricted stock units and performance-based awards with performance conditions is determined by the grant-date closing price of WESCO’s common stock. The forfeiture assumption is based on WESCO’s historical employee behavior that is reviewed on an annual basis. No dividends are assumed. For stock-settled stock appreciation rights that are exercised and for restricted stock units and performance-based awards that vest, shares are issued out of WESCO's outstanding common stock.Table of ContentsWESCO INTERNATIONAL, INC. AND SUBSIDIARIESNOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(CONTINUED)86Stock-settled stock appreciation rights vest ratably over a three-year period and terminate on the tenth anniversary of the grant date unless terminated sooner under certain conditions. Except for the special award described below, vesting of restricted stock units is based on a minimum time period of three years. Vesting of performance-based awards is based on a three-year performance period, and the number of shares earned, if any, depends on the attainment of certain performance levels. Outstanding awards would vest upon the consummation of a change in control transaction and performance-based awards would vest at the target level.On July 2, 2020, a special award of restricted stock units was granted to certain officers of the Company. These awards vest in tranches of 30% on each of the first and second anniversaries of the grant date and 40% on the third anniversary of the grant date, subject, in each case, to continued employment through the applicable anniversary date.Performance-based awards granted in 2020 and 2019 were based on two equally-weighted performance measures: the three-year average growth rate of WESCO's net income and the three-year cumulative return on net assets. Performance-based awards granted in 2018 were based on two equally-weighted performance measures: the three-year average growth rate of the Company’s fully diluted earnings per share and the three-year cumulative return on net assets.WESCO recognized $19.3 million, $19.1 million and $16.4 million of non-cash stock-based compensation expense, which is included in selling, general and administrative expenses, for the years ended December 31, 2020, 2019 and 2018, respectively. As of December 31, 2020, there was $33.5 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements for all awards previously made of which approximately $17.6 million is expected to be recognized in 2021, $12.3 million in 2022 and $3.6 million in 2023.The total intrinsic value of awards exercised during the years ended December 31, 2020, 2019, and 2018 was $8.8 million, $10.7 million, and $8.2 million, respectively. The gross deferred tax benefit associated with the exercise of stock-based awards totaled $2.0 million, $2.5 million, and $2.0 million in 2020, 2019, and 2018, respectively.The following table sets forth a summary of stock-settled stock appreciation rights and related information for the periods presented:Year Ended December 31, 202020192018AwardsWeighted-AverageExercisePriceWeighted-AverageRemainingContractualLifeAggregateIntrinsicValue(In thousands)AwardsWeighted-AverageExercisePriceAwardsWeighted-AverageExercisePriceBeginning of year 2,337,049 $ 59.72    2,351,633 $ 59.26  2,238,607 $ 57.75 Granted 262,091  48.32    213,618  54.63  509,046  62.68 Exercised (391,339)  47.11    (113,099)  35.01  (192,700)  40.74 Canceled (46,245)  65.93    (115,103)  65.27  (203,320)  68.69 End of year 2,161,556  60.48 5.7$ 39,834  2,337,049  59.72  2,351,633  59.26 Exercisable at end of year 1,630,891 $ 62.72 4.8$ 26,622  1,723,370 $ 59.00  1,453,932 $ 57.93 The following table sets forth the weighted-average assumptions used to estimate the fair value of stock-settled stock appreciation rights granted during the periods presented:Year Ended December 31,202020192018Stock-settled stock appreciation rights granted262,091213,618509,046   Risk free interest rate1.4%2.5%2.5%   Expected life (in years)555   Expected volatility30%29%28%The risk-free interest rate is based on the U.S. Treasury Daily Yield Curve rate as of the grant date.

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.16. COMMITMENTS AND CONTINGENCIESFrom time to time, a number of lawsuits and claims have been or may be asserted against the Company relating to the conduct of its business, including litigation relating to commercial, product and employment matters. The outcome of any 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.In an effort to expand the Company's footprint in the Middle East, WESCO has been doing business since 2009 with WESTEC Supplies General Trading (“WESTEC”), an industrial equipment supplier headquartered in the United Arab Emirates. WESTEC has debt facilities comprised of a $5.5 million term loan and a $1.0 million line of credit to support its working capital requirements and joint sales efforts with WESCO. Due to the nature of WESCO’s arrangement with WESTEC, WESCO has provided a standby letter of credit under its revolving credit facility of up to $6.7 million as security for WESTEC’s debt facilities. As of December 31, 2020, WESTEC had outstanding indebtedness totaling $5.8 million. Management currently believes the estimated fair value of the noncontingent guarantee on the outstanding indebtedness is nominal and therefore a liability has not been recorded as of December 31, 2020.As of December 31, 2020, the Company had $54.1 million in outstanding letters of credit and guarantees.Table of ContentsWESCO INTERNATIONAL, INC.

17. BUSINESS SEGMENTS

Prior to the completion of its merger with Anixter on June 22, 2020, as described in Note 6, "Acquisitions", WESCO had 
four operating segments that had been aggregated as one reportable segment. Effective on the date of acquisition, the Company 
added  Anixter  as  a  separate  reportable  segment  for  the  quarterly  period  ended  June  30,  2020.  At  the  beginning  of  the  third 
quarter, the Company identified new operating segments organized around three strategic business units consisting of EES, CSS 
and  UBS.  These  operating  segments  are  equivalent  to  the  Company's  reportable  segments.  The  operating  segments  in  the 
respective  periods  were  determined  in  accordance  with  the  manner  in  which  WESCO's  chief  operating  decision  maker 
("CODM")  reviewed  financial  information  during  those  periods.  The  Company's  CODM  evaluates  the  performance  of  its 
operating segments based primarily on net sales, income from operations, and total assets. The applicable comparative financial 
information reported in the Company's previously issued consolidated financial statements for the years ended December 31, 
2019 and 2018 has been recast below to conform to the basis of the new segments.

The following is a description of each of the Company's reportable segments and their business activities.

Electrical & Electronic Solutions

The EES segment supplies a broad range of products and supply chain solutions primarily to the Construction, Industrial and 
Original  Equipment  Manufacturer  ("OEM")  markets.  Product  categories  include  a  broad  range  of  electrical  equipment  and 
supplies, wire and cable, 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.  EES  includes  the  “Electrical  and  Electronic  Solutions”  business  acquired  from 
Anixter and the majority of the legacy WESCO industrial and construction businesses.

Communications & Security Solutions

The  CSS  segment  supplies  products  and  customized  supply  chain  solutions  to  customers  in  a  diverse  range  of  industries 
including  technology,  finance,  telecommunications  service  providers,  transportation,  education,  government,  healthcare  and 
retail. CSS sells these products directly to end users or through various channels including data communications contractors, 
security, network, professional audio/visual and systems integrators. CSS has a broad product portfolio that includes copper and 
fiber  optic  cable  and  connectivity,  access  control,  video  surveillance,  intrusion  and  fire/life  safety,  cabinets,  power,  cable 
management, wireless, professional audio/video, voice and networking switches and other ancillary products. CSS includes the 
“Network  and  Security  Solutions”  business  acquired  from  Anixter  and  the  legacy  WESCO  data  communications  and  safety 
businesses.

Utility & Broadband Solutions

The UBS segment supplies electrical transmission and distribution products, power plant maintenance, repair and operations 
supplies and smart-grid products, and arranges materials management and procurement outsourcing for the power generation, 
power transmission and electricity distribution industries. The UBS segment combines the “Utility Power Solutions” business 
acquired from Anixter, the legacy WESCO utility business, the legacy WESCO broadband business and the legacy WESCO 
integrated supply business.

Corporate  expenses  are  incurred  to  obtain  and  coordinate  financing,  tax,  information  technology,  legal  and  other  related 
services.  The  Company  also  has  various  corporate  assets  which  are  reported  in  corporate.  Segment  assets  may  not  include 
jointly used assets, but segment results include depreciation expense or other allocations related to those assets. Interest expense 
and other non-operating items are not allocated to the segments or reviewed on a segment basis. Corporate expenses and assets 
are shown in the tables below to reconcile the reportable segments to the consolidated financial statements.

Thus, the sum of the four quarters’ EPS may not equal the full-year EPS.(3) 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.19. SUBSEQUENT EVENTSOn January 14, 2021 (the “Redemption Date”), WESCO Distribution, Inc. redeemed its $500 million aggregate principal amount of 5.375% Senior Notes due 2021 (the "2021 Notes") at a redemption price equal to 100% of the principal amount of the 2021 Notes plus accrued interest on the 2021 Notes to, but not including, the Redemption Date. The redemption of the 2021 Notes was funded with borrowings under the Company's accounts receivable securitization and revolving credit facilities.On February 1 and 12, 2021, the Company sold its legacy WESCO Utility and Datacom businesses in Canada, respectively, for cash consideration totaling approximately $52 million. These transactions fulfill the Company’s commitment to divest these businesses in connection with its Consent Agreement with the Canadian Competition Bureau related to the merger with Anixter. The Company expects to use the net proceeds from the divestiture to repay indebtedness.Table of ContentsWESCO INTERNATIONAL, INC.

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 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, 2020.

As permitted by Securities and Exchange Commission guidance, management excluded Anixter Inc. from its assessment of 
internal  control  over  financial  reporting,  which  was  acquired  on  June  22,  2020,  and  accounted  for  approximately  30%  of 
consolidated total assets and 37% of consolidated net sales as of and for the year ended December 31, 2020.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2020 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  2020,  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.
