CEO LETTER

Dear Fellow Stakeholders,

It is a privilege to write to you for the  
first time to report on CDW’s 2018 
financial and strategic performance and 
to share our intentions looking forward.

CDW is stronger and our prospects 
are as promising as at any time in our 
35-year history. In 2018, we profitably 
gained market share delivering on 
our perennial objective to outperform 
technology sector growth by a 
meaningful amount. We produced 
a record $16.2 billion in net sales, an 
increase of 9.2 percent in constant 
currency. An evolving product mix, 
productivity improvements, disciplined 
expense management and forward-
looking investment in our Bold Forward 
strategic plan translated this growth 
into a 9.8 percent increase in adjusted 
EBITDA. A benefit from the Tax Cuts 
and Jobs Act amplified operating 
earnings, and share repurchases further 
contributed to non-GAAP earnings per 
share which increased 35.1 percent. 

The Customer at the Center

In 2018, CDW’s integrated technology 
solutions and services helped more 
than 250,000 business, government, 
education and healthcare customers 
throughout the United States, the 
United Kingdom and Canada navigate 
an increasingly complex IT landscape 
and optimize the return on their 
technology investment. 

2018 results reflect the power of 
our business model, CDW’s high-
performance culture embodied in 
the commitment and skillsets of our 
coworkers, and the strategic vision, 
collaboration and leadership of our 

management team. CDW’s value 
proposition is to advance the objectives 
of our customers by optimizing their 
limited technology resources to achieve 
their respective goals. We support this 
through broad, deep and experienced 
capabilities and comprehensive,  
unbiased orchestration of technology.

CDW’s consistent record of success is 
rooted in our ability to evolve and be 
even more relevant to customers as 
technology advances and becomes more 
essential to organizations throughout 
market segments that we serve. 
Technology has always and will continue 
to progress. CDW has been the reliable 
constant by being a continually evolving 
and improving organization. We have 
maintained a steadfast focus on our 
customers and earned our industry-
leading position in partnership with more 
than 1,000 brands offering more than 
100,000 products. CDW’s commitment 
to ensure our customers’ success has 
been our distinguishing quality since our 
founding on Michael Krasny’s kitchen 
table with a classified advertisement 
of a 512K memory personal computer 
in 1984. This is the essence of our 
customer-centric, three-part strategy.  
It is, at heart, why We Get IT!

Proven Strategy
Our growth strategy has three 
foundational pillars—each is integral 
to our profitably delivering integrated 
technology solutions that our 
customers want and need. We  
see these pillars as three booster 
engines—all are interconnected and 
involve individual and collaborative 
efforts in the successful execution  
of our forward-looking mission.

CDW’s consistent record of success is rooted in our ability to evolve and be 
even more relevant to customers as technology advances and becomes more 
essential to organizations throughout market segments that we serve.

Christine A. Leahy

President and Chief Executive Officer 

The first engine drives continuous sales 
and sales productivity gains, which 
facilitates our repeatable acquisition, 
retention and growth of customers and 
market share. Productivity improvements 
and expense management fuel our ability 
to invest in profitable growth and provide 
value to our customers and partners and 
opportunity for our coworkers. During 
2018, sales productivity investments 
included the expansion of ServiceTrack, 
CDW U.K.’s award-winning online supply 
chain management portal, to U.S.-based 
multinational customers; enhancement 
of our eCommerce platform; expansion of 
CDW’s Residency Program for new sales 
representatives and our “graduate level” 
sales training initiative; and the rollout of 
a propensity modeling tool that uses data 
analytics and CDW proprietary data to 
identify what customers are most likely  
to need and further benefit from. 

We expanded our local presence in the 
U.S. to more than 26 major metropolitan 
locations with the opening of a new sales 
and service delivery office in Nashville, 
Tennessee. We also drove partner 
productivity through investments in 
automated partner processes, including 
the launch of a new Partner Portal. 

CDW CORPORATION  1

Repeatedly achieving above-market growth requires capabilities for delivering  
the solutions customers need today and will need out on the horizon. 

Being Ever-Vital
Our rigorous strategic planning process 
guides our effective evolution with the 
technology landscape while delivering 
market-leading profitable growth. It also 
facilitates our being increasingly vital to 
our customers. 

Our current Bold Forward three-year 
strategic plan is designed to continue 
and to elevate our consistent record of 
success. Using similar processes and 
frameworks as our prior plans, Bold 
Forward is fueled by CDW’s broad and 
deep understanding of technology 
industry dynamics relevant for our 
customers, including our unique 
institutional knowledge. With appreciation 
for CDW’s heritage as the market leader 
in providing technology solutions and 
services, our coworkers are committed  
to and passionate about pursuing 
emerging technology frontiers in the 
service of our customers and partners. 

Market-leading technology is no longer 
an option or simply a potential strategic 
consideration—it has become and will 
remain vital to our customers’ success. 
The reality of needing to objectively 
evaluate and integrate technology 
investments is at the essence of our value 
proposition for our customers. CDW’s 
strategic investments are prioritized 
to ensure that as technology and our 
customers’ needs evolve, we remain 
well-equipped to support our customers 
through every phase of the technology 
lifecycle:  evaluate, design, access, 
implement, adopt, manage, enhance, 
renew.... Through this process, we 
develop “stickiness” and deep customer 
loyalty that drives profitable growth. 

A recent example of Bold Forward’s 
success is our early 2019 acquisition 
of Scalar Decisions Inc., a Canadian 
integrated technology solutions 
provider. Scalar expands our CDW 
Canada solutions and services portfolio, 
extends our solutions presence across 
Canada and enhances the value that we 
deliver to our customers. As with our 

Our rigorous strategic planning process guides our effective evolution with  
the technology landscape while delivering market-leading profitable growth.  
It also facilitates our being increasingly vital to our customers.

These, among other investments, 
contributed to net sales per coworker 
increasing at nearly double the rate of 
coworker additions. 

Repeatedly achieving above-market 
growth requires capabilities for delivering 
the solutions customers need today and  
will need out on the horizon. Our second 
and third strategic boosters address 
these objectives. Designed to ensure 
we remain relevant to customers and 
partners, investments in these engines 
strategically focus on enhancing and 
expanding our solutions and services 
capabilities. One way we accomplish 
this is by adding highly-skilled technical 
coworkers. At year-end 2018, our 
technical organization included more 
than 2,500 coworkers, reflecting an 
increase of nearly 50 percent over  
five years.

CDW’s methodical addition of new 
and emerging OEM partners keeps 
our portfolio optimally relevant and 
provides new levers for growth,  
while adding value for our customers, 
opportunity for our coworkers and 
returns for our shareholders. In 2018, 
we added more than 80 partners,  
with nearly half delivering cloud- 
based, security and advanced data 
center solutions. We also launched  
two CDW branded service solutions: 
CDW Technology Support, which 
provides warranty support service; 
and CDW Managed Collaboration 
Anywhere, which allows customers to 
access fully-managed collaboration 
tools across any platform from 
anywhere with maximum flexibility  
to scale. Services was one of our 
fastest growing categories in 2018.

2  CDW CORPORATION

 
 
 
successful 2015 acquisition of CDW U.K., 
Scalar’s culture is strongly aligned with 
CDW’s, having an exceptional focus on 
and commitment to customer objectives 
and coworker fulfillment. 

Commitment to Shareholders and  
to All CDW Stakeholders

Our strategic plan encompasses 
performance and capital allocation 
priorities that are designed to deliver 
compelling returns to investors both in 
the near-term and over the long-term. 
2018’s strong cash flows enabled us to 
return a record of more than $650 million 
to shareholders by means of share 
repurchases and dividends. Reflecting 
confidence in our performance, strategy 
and outlook, the Board of Directors 
approved a 40 percent increase in our 
annual cash dividend and an incremental 
and record $1 billion authorization for 
share repurchases. 

We will never take for granted our 
reputation with our customers, 
coworkers, partners, shareholders and 
communities where we employ, live and 
have impact—a reputation that has been 
built over 35 years through relentless 
commitment, dedication, hard work, 
philanthropic contributions and complete 
integrity. I assure you that every single 
day during my time as the leader of 
your Company and as your fellow 
stakeholder, CDW will continue to never 
allow for complacency regarding our 
business performance or anything less 
than the full commitment to serving our 
customers and enhancing the value of our 
shareholders’ investments and the lives

of our stakeholders. The means will be 
as important and non-negotiable as the 
ends. This is my commitment to you.

Thank You
This letter would not be complete 
without recognizing my predecessor, 
mentor and friend, Thomas E. Richards. 
Tom served and led CDW for nine years 
with passion, discipline and heart. Under 
Tom’s leadership, CDW consistently 
delivered market-leading performance–
accordingly, another commitment  
I have made is to also serve in a manner 
that will ultimately leave CDW a 
meaningfully better organization. 

I would also like to recognize the 
commitment, dedication and 
performance of our more than  
9,000 coworkers throughout  
2018 and exhort you to embrace,  
as you have throughout your careers 
and CDW’s history, welcoming the  
challenge of attaining even greater 
success in 2019. Individually and 
collectively YOU are CDW...YOU 
are CDW’s evergreen competitive 
advantage...the manner with which  

We will never take for granted our reputation with our customers, coworkers, 
partners, shareholders, and communities where we employ, live and have impact— 
a reputation that has been built over 35 years through relentless commitment, 
dedication, hard work, philanthropic contributions and complete integrity.

CDW sits between customers and vendor 
partners, creating unique value for both:

Customers get access to a broad selection 
of multi-branded solutions and deeply 
technical resources, including highly-skilled, 
extensively certified specialists and 
engineers. CDW is an extension of its 
customers’ IT staffs.

Partners get access to CDW’s more than 
250,000 customers and augment their 
product offerings with a wide range of 
value-added IT and distribution services. 
CDW is an extension of its partners’ sales 
and marketing resources.

you continue to serve our customers 
and our partners will be the determining 
factor for CDW’s future. It is truly 
an honor to lead such a capable and 
committed team.

Thank you customers, partners and 
shareholders for entrusting your 
businesses and your hard-earned  
and valuable assets to our care and  
to our commitment to achieve and 
exceed your objectives for growth. 

I am confident that our thoughtful 
strategy, ample resources, leading 
marketplace position and vigorous 
dedication will once again deliver 
meaningfully above-market profitable 
growth in 2019. I look forward with 
resolve and enthusiasm to next  
year’s report. 

As I regularly conclude my 
communication with CDW  
coworkers, Bring IT!

Item 1. Business

Our Company

PART I

CDW Corporation (together with its subsidiaries, the "Company," "CDW" or "we") is a Fortune 500 company and a 
leading provider of integrated information technology ("IT") solutions to small, medium and large business, government, education 
and healthcare customers in the United States ("US"), the United Kingdom ("UK") and Canada. Our broad array of offerings 
ranges from discrete hardware and software products to integrated IT solutions such as mobility, security, data center optimization, 
cloud computing, virtualization and collaboration. 

We are technology "agnostic," with a solutions portfolio including more than 100,000 products and services from more 
than 1,000 leading and emerging brands. Our solutions are delivered in physical, virtual and cloud-based environments through 
over  6,000  customer-facing  coworkers,  including  sellers,  highly-skilled  technology  specialists  and  advanced  service  delivery 
engineers. We are a leading sales channel partner for many original equipment manufacturers ("OEMs"), software publishers and 
cloud providers (collectively, our "vendor partners"), whose products we sell or include in the solutions we offer. We provide our 
vendor partners with a cost-effective way to reach customers and deliver a consistent brand experience through our established 
end-market coverage, technical expertise and extensive customer access.

We simplify the complexities of technology across design, selection, procurement, integration and management for our 
customers. Our goal is to have our customers, regardless of their size, view us as a trusted adviser and extension of their IT 
resources. We do not manufacture products. Our multi-brand offering approach enables us to identify the products or combination 
of products from our vendor partners that best address each customer's specific IT requirements.

We provide integrated IT solutions in more than 80 countries for customers with primary locations in the US, UK and 
Canada, which are large and growing markets. According to the International Data Corporation ("IDC"), the total US, UK and 
Canadian IT market generated approximately $1 trillion in sales in 2018. We believe our addressable markets in the US, UK and 
Canada represent more than $325 billion in annual sales. These are highly fragmented markets served by thousands of IT resellers 
and solutions providers. For the year ended December 31, 2018, we estimate that our total Net sales of $16 billion represented 
approximately 5% of our addressable markets. We believe that demand for IT will continue to outpace general economic growth 
in the markets we serve fueled by new technologies, including cloud computing, virtualization and mobility as well as growing 
end-user demand for security, efficiency and productivity. 

Value Proposition 

We are positioned in the middle of the IT ecosystem where we procure products from OEMs, software publishers, cloud 
providers and wholesale distributors and provide added value to our customers by helping them navigate through complex options 
and implement the best solution for their business. In this role, we believe we provide unique value to both our vendor partners 
and our customers.

healthcare customers throughout the US, UK and Canada. 

We serve our customers through sales teams focused on customer end-markets that are supported by technical specialists

We have three reportable segments, Corporate, Small Business and Public. Our Corporate segment primarily serves US 
private sector business customers with more than 250 employees. Our Small Business segment primarily serves US private sector 
business  customers  with  up  to  250  employees.  Our  Public  segment  is  comprised  of  government  agencies  and  education  and

healthcare institutions in the US. We also have two other operating segments: CDW UK and CDW Canada, each of which do not 
meet the reportable segment quantitative thresholds and, accordingly, are included in an all other category ("Other"). 

In our US business, which represents approximately 90% of our revenues, we currently have five dedicated customer 
channels: corporate, small business, government, education and healthcare, each of which generated over $1.0 billion in Net sales 
in 2018. Net sales to customers in the UK and Canada combined generated $1.9 billion in 2018.  We believe this diversity of 
customer end-markets provides us with multiple avenues for growth and has been a key factor in our ability to weather economic 
and technology cycles and continue to gain market share. 

Partners

We provide more than 100,000 products and services from more than 1,000 partners, including well-established companies 
such as Adobe, APC, Apple, Cisco, Dell EMC, Google, Hewlett Packard Enterprise, HP Inc., IBM, Intel, Lenovo, Microsoft, 
NetApp,  Samsung,  Symantec  and  VMware,  as  well  as  from  emerging  technology  companies  such  as  Calabrio,  Cohesity, 
Crowdstrike, Nutanix, Proofpoint, Splunk, Varidesk, Veeam and Viptela. This broad portfolio of partners and technologies enables 
us to offer customers significant choice and meet customer demand for the products and solutions that best meet their needs. We 
believe our value proposition to vendor partners enables us to evolve our offering as new technologies emerge and new companies 
seek us as a channel partner.

In 2018, we generated over $1.0 billion of Net sales from each of five of our vendor partners and over $100 million of 
revenue from each of thirteen other vendor partners. We have received the highest level of certification from major vendor partners 
such as Cisco, Dell EMC, Hewlett Packard Enterprise, Microsoft and Palo Alto Networks, which reflects the extensive product 
and solution knowledge and capabilities that we bring to our customers' IT challenges. These certifications also provide us with 
access to favorable pricing, tools and resources, including vendor incentive programs, which we use to provide additional value 
to our customers. Our vendor partners also regularly recognize us with top awards and select us to develop and grow new customer 
solutions.

Product Procurement

We may purchase all or only some of the products our vendor partners offer for resale to our customers or for inclusion 
in the solutions we offer. Each vendor partner agreement provides for specific terms and conditions, which may include one or 
more of the following: product return privileges, price protection policies, purchase discounts and vendor incentive programs, 
such as, purchase or sales rebates and cooperative advertising reimbursements. We also purchase software from major software 
publishers and cloud providers for resale to our customers or for inclusion in the solutions we offer. Our agreements allow the 
end-user customer to acquire cloud-based solutions software or licensed products and services.

In addition to purchasing products directly from our vendor partners, we purchase products from wholesale distributors 
for resale to our customers or for inclusion in the solutions we offer. These wholesale distributors provide logistics management 
and supply-chain services for us, as well as for our vendor partners.

For our US operations, we purchased approximately 50% of the products we sold as discrete products or as components 
of a solution directly from our vendor partners and the remaining 50% from wholesale distributors for the year ended December 
31, 2018. Purchases from our three largest wholesale distributors, Ingram Micro, SYNNEX and Tech Data, were each approximately 
10% of total US purchases in 2018. 

Inventory Management

We operate two distribution centers in North America: a 513,000 square foot facility in North Las Vegas, Nevada, and a 
442,000  square  foot  facility  in  Vernon  Hills,  Illinois.  We  also  operate  a  120,000  square  foot  distribution  center  in  Rugby, 
Warwickshire, UK.  We ship over 40 million units annually on an aggregate basis from our distribution centers. 

We also have drop-shipment arrangements with many of our OEMs and wholesale distributors, which permit us to offer 
products to our customers without having to take physical delivery at our distribution centers. These arrangements represented 
approximately 50% of total consolidated Net sales in 2018, of which approximately 25% relate to electronic delivery for software 
licenses.

We believe that the location of our distribution centers allows us to efficiently ship products to our customers and provide 

timely access to our principal distributors.

We believe competitive sources of supply are available in substantially all of the product categories that we offer.

Competition

The market for technology products and services is highly competitive and subject to economic conditions and rapid 
technological changes. Competition is based on many things, including the ability to tailor specific solutions to customer needs, 
the quality and breadth of product and service offerings, knowledge and expertise of sales force, customer service, price, product 
availability,  speed  of  delivery  and  credit  availability. We  face  competition  from  resellers,  direct  manufacturers,  large  service 
providers, cloud providers, telecommunication companies, and to a lesser extent e-tailers and retailers. Smaller, local or regional 
value added resellers typically focus on a single solution suite or portfolio of solutions from one or two vendor partners. 

We believe we are well positioned to compete within this marketplace due to our competitive advantages. We expect the 
competitive landscape to continue to evolve as new technologies are developed. While innovation can help our business as it 
creates new offerings for us to sell, it can also disrupt our business model and create new and stronger competitors. For a discussion 
of the risks associated with competition, see Item 1A, "Risk Factors."

We believe we have sustainable competitive advantages that differentiate us in the marketplace.  We have built a strong 
sales  organization  and  deep  services  and  solutions  capabilities  over  time  and  expect  to  continue  to  invest  to  enhance  these 
capabilities, which we believe when combined with our competitive advantages of scale and a performance driven culture, will 
help drive sustainable, profitable growth for us today and in the future. Our scale enables us to have a national and international 
footprint, as well as invest in resources to meet specific customer end-market needs. Our sellers are organized around unique 
customer end-markets that are both vertically and geographically focused. Our scale enables our ability to invest in technical 
coworkers who work directly with our sellers to help customers implement increasingly complex IT solutions. Our scale also 
enables us to operate our three distribution centers (two in the US and one in the UK) which combined are more than 1 million 
square feet in size. We have cross-border relationships that enable us to serve the needs of our US, UK and Canadian-based 
customers in more than 80 countries. Our strong, execution-oriented culture is underpinned by our compensation system.

Our Offerings

Our offerings range from discrete hardware and software products and services to complex integrated solutions including 
one or more of these elements. We believe our customers increasingly view technology purchases as integrated solutions rather 
than discrete product and service categories. We estimate that more than 40% of our Net sales in 2018 in the US came from sales 
of product categories and services typically associated with solutions. Our hardware products include notebooks/mobile devices 
(including tablets), network communications, desktop computers, video monitors, enterprise and data storage, printers and servers. 
Our software products include application suites, security, virtualization, operating systems and network management. Our services 
include warranties, managed services, consulting design and implementation.

Today, IT is critical to both "run the business" and drive greater growth and productivity. To help our customers accomplish 
this, we have built a robust portfolio of solutions across data center, digital workspace, security, virtualization and services that 
we provide in physical, virtual, or cloud-based environments. 

We provide public cloud solutions, which reside off customer premises on a public (shared) infrastructure, and private 
cloud solutions, which reside on customer premises. We also offer hybrid cloud solutions that deliver the benefits of both public 
and private solutions. Our migration, integration and managed services offerings help our customers simplify cloud adoption, as 
well as the ongoing management of cloud solutions across the entire IT lifecycle. Dedicated Cloud Client Executives work with 
our customers to architect cloud solutions meeting their organizational, technology and financial objectives. 

We offer a broad portfolio of integrated solutions that include the following on and off-premise capabilities:

• 

• 

Data Center: We assess our customers data center needs, design flexible, resilient and efficient solutions and manage the 
solution throughout its lifecycle. Our broad portfolio of hardware and software products, encompassing both on and off-
premise  solutions,  enables  us  to  provide  well-integrated  solutions,  including  converged  and  hyper-converged 
infrastructure, physical and virtualized servers, software defined automation and orchestration solutions, storage and 
energy-efficient power and cooling.

Digital  Workspace:  We  build  end-to-end  solutions  that  deliver  access  to  applications  that  improve  our  customers' 
productivity regardless of device or location.  We connect our customers' physical devices, including laptops, desktops, 
IP Phones, mobile devices and print systems. We utilize collaboration solutions to unite applications via the integration 
of products that facilitate the use of multiple enterprise communication methods including email, persistent chat, social 
media, voice and video. We also host cloud-based collaboration solutions. Our solutions provide the tools that allow our 
customers'  employees  to  share  knowledge,  ideas  and  information  among  each  other  and  with  clients  and  partners 
effectively, securely and quickly.

Security: We assess our customers' security needs and provide them with risk mitigation tools and services. Product 
design, architecture and implementation can take the form of hardware, software or Software as a Service. These tools 
and services are provided across a multitude of categories such as: endpoint security, email security, web security, intrusion 
prevention, authentication, firewall, virtual private network services and network access control. Security consulting 
engagements include security assessment, policy and procedure gap analysis, security roadmaps and healthchecks.

Virtualization: We design and implement server, storage and desktop virtualization solutions. Virtualization enables our 
customers to efficiently utilize hardware resources by running multiple, independent, virtual operating systems on a single 
computer  and  multiple  virtual  servers  simultaneously  on  a  single  server.  Virtualization  also  can  separate  a  desktop 
environment and associated application software from the hardware device that is used to access it, and provides employees 
with remote desktop access. Our specialists assist customers with the steps of implementing virtualization solutions, 
including evaluating network environments, deploying shared storage options and licensing platform software.

Services: We advise on, architect and manage integrated business technology for our customers.  Our solutions include 
integrated cloud, collaboration, data center, mobility and security business technology, from the physical to the application 
layer.  We provide advisory, architectural and managed services across basic, discrete and integrated business technology 
solutions.    We  leverage  best-in-class  partner  technology  platforms  to  seamlessly  architect  and  manage  disparate  IT 
platforms into integrated business technology solutions.  

Although we believe customers increasingly view technology purchases as solutions rather than discrete product and 

service categories, our Net sales by major category, based upon our internal category classifications was as follows:

Our Internal Capabilities

Our Coworkers

As of December 31, 2018, we employed 9,019 coworkers with approximately 7,200 coworkers in the US, 1,300 in the 
UK and 500 in Canada. Approximately two thirds of our coworkers at year-end 2018 were customer facing.  Over 50% of our Net 
sales are generated by account managers who have greater than seven years of tenure with CDW. Account managers are supported 
by field sellers, highly skilled technology specialists and advanced service delivery engineers. We believe this structure to be core 
to our ability to continue to offer complex IT solutions and services. None of our coworkers are covered by collective bargaining 
agreements. We consider our coworker relations to be good.

Marketing

We market the CDW brand to US, UK and Canada audiences using a variety of channels that include online, broadcast, 
print, social and other media. We market to current and prospective customers through integrated marketing programs including 
behaviorally targeted email, print, online media, events and sponsorships, as well as broadcast media. This promotion is also 
supported by integrated communication efforts targeting decision-makers, influencers and the general public using a combination 
of news releases, case studies, media interviews and speaking opportunities.

As a result of our relationships with our vendor partners, a significant portion of our advertising and marketing expenses 
is reimbursed through cooperative advertising programs. These programs are at the discretion of our vendor partners and are 
typically tied to sales or other commitments to be met by us within a specified period of time. We believe that our results and 
analytical techniques that measure the efficacy of our marketing programs differentiate us from our competitors.

Information Technology Systems

We maintain customized IT and unified communication systems that enhance our ability to provide prompt, efficient and 
expert service to our customers. In addition, these systems enable centralized management of key functions, including purchasing, 
inventory management, billing and collection of accounts receivable, sales and distribution. Our systems provide us with thorough, 
detailed  and  real-time  information  regarding  key  aspects  of  our  business.  This  capability  helps  us  to  continuously  enhance 
productivity, ship customer orders quickly and efficiently, respond appropriately to industry changes and provide high levels of 
customer service. We believe our websites, which provide electronic order processing and advanced tools, such as order tracking, 
reporting and asset management, make it easy for customers to transact business with us and ultimately strengthen our customer 
relationships.

Intellectual Property

The CDW trademark and certain variations thereon are registered or subject to pending trademark applications in the US, 
UK, Canada and certain other jurisdictions. We believe our trademarks have significant value and are important factors in our 
marketing programs. In addition, we own registrations for domain names, including cdw.com and cdwg.com and variations thereon, 
for certain of our primary trademarks. We also own patent rights and have unregistered copyrights in our website content, software 
and other written materials. 

History

Founded in 1984, CDW became a public company in 1993. In 2003, we purchased selected US assets and the Canadian 
operations of Micro Warehouse, which extended our growth platform into Canada. In 2006, we acquired Berbee Information 
Networks Corporation, a regional provider of technology products, solutions and customized engineering services in advanced 
technologies primarily across Cisco, IBM and Microsoft portfolios. This acquisition increased our capabilities in customized 
engineering services and managed services.

We were a public company from 1993 until 2007 when we were acquired through a merger transaction by an entity 
controlled by investment funds affiliated with Madison Dearborn Partners, LLC ("Madison Dearborn") and Providence Equity 
Partners L.L.C. ("Providence Equity"). In 2013, CDW Corporation completed a second IPO of its common stock. After the IPO, 
through secondary offerings and fund distributions, Madison Dearborn and Providence Equity liquidated their ownership positions. 

 In 2015, we acquired control of 100% of UK-based IT solutions provider, Kelway TopCo Limited ("Kelway"). Rebranded 
CDW UK in 2016, the acquisition extended our footprint into the UK. It also enhanced our ability to provide IT solutions to US-
based customers with multinational locations.

Item 1A. Risk Factors

There are many factors that could adversely affect our business, results of operations and cash flows, some of which are beyond 
our control. The following is a description of some important factors that may cause our business prospects, results of operations 
and cash flows in future periods to differ materially from those currently expected or desired. Factors not currently known to us 
or that we currently deem to be immaterial may also materially and adversely affect our business, results of operations and cash 
flows.

Risks Related to Our Business

Global and regional economic and political conditions may have an adverse impact on our business.

Weak economic conditions generally, sustained uncertainty about global economic and political conditions, government 
spending cuts and the impact of new government policies, or a tightening of credit markets, could cause our customers and potential 
customers to postpone or reduce spending on technology products or services or put downward pressure on prices, which could 
have an adverse effect on our business, results of operations or cash flows. For example, there continues to be substantial uncertainty 
regarding the economic impact of the Referendum on the UK's Membership of the European Union ("EU") advising for the exit 
of the UK from the EU and the subsequent notice delivered by the UK to the EU of the UK's withdrawal (referred to as "Brexit").   
Negotiations to determine the terms of the withdrawal, including the terms of trade between the UK and the EU, are ongoing. 
Although the full effects of Brexit are uncertain and will be dependent on the outcome of such negotiations, potential adverse 
consequences of Brexit include global market uncertainty, volatility in currency exchange rates, greater restrictions on imports 
and exports between the UK and EU countries and increased regulatory complexities, each of which could have a negative impact 
on our business, financial condition and results of operations.

Our financial performance could be adversely affected by decreases in spending on technology products and services by our 
public sector customers. 

Our sales to our public sector customers and our other customers that do business with our public sector customers are 
impacted by government spending policies, budget priorities and revenue levels. An adverse change in government spending 
policies (such  as budget cuts  or limitations or temporary shutdowns  of  government operations), shifts  in budget priorities or 
reductions in revenue levels could cause our public sector customers or our other customers that do business with impacted public 
sector customers to reduce or delay their purchases or to terminate or not renew their contracts with us, which could adversely 
affect our business, results of operations or cash flows. Additionally, such adverse change in government spending policies, shifts 
in budget priorities or reductions in revenue levels could impact cash collections from contracts with our other customers that do 
business with impacted public sector customers, which could adversely affect our business, results of operations or cash flows.

Our business depends on our vendor partner relationships and the availability of their products.

Our solutions portfolio includes products from OEMs, software publishers and cloud providers. We are authorized by 
these vendor partners to sell all or some of their products via direct marketing activities. Our authorization with each vendor partner 
is subject to specific terms and conditions regarding such things as sales channel restrictions, product return privileges, price 
protection policies, purchase discounts and vendor partner programs and funding, including purchase rebates, sales volume rebates, 
purchasing incentives and cooperative advertising reimbursements. However, we do not have any long-term contracts with our 
vendor partners and many of these arrangements are terminable upon notice by either party. A reduction in vendor partner programs 
or funding or our failure to timely react to changes in vendor partner programs or funding could have an adverse effect on our 
business, results of operations or cash flows. In addition, a reduction in the amount or a change in the terms of credit granted to 
us by our vendor partners could increase our need for, and the cost of, working capital and could have an adverse effect on our 
business, results of operations or cash flows, particularly given our substantial indebtedness. 

From time to time, vendor partners may terminate or limit our right to sell some or all of their products or change the 
terms and conditions or reduce or discontinue the incentives that they offer us. For example, there is no assurance that, as our 
vendor partners continue to sell directly to end users and through resellers, they will not limit or curtail the availability of their 

9

Table of Contents

products to solutions providers like us. Any such termination or limitation or the implementation of such changes could have a 
negative impact on our business, results of operations or cash flows. 

We purchase the products included in our solutions portfolio both directly from our vendor partners and from wholesale 
distributors. Although we purchase from a diverse vendor base, in 2018, products we purchased from wholesale distributors Ingram 
Micro,  SYNNEX  and  Tech  Data  each  represented  approximately  10%  of  total  US  purchases.  In  addition,  sales  of  products 
manufactured by Apple, Cisco, Dell EMC, Hewlett Packard Enterprise, HP Inc., Lenovo and Microsoft, whether purchased directly 
from these vendor partners or from a wholesale distributor, represented in the aggregate nearly 60% of our 2018 consolidated Net 
sales. Sales of products manufactured by Cisco and HP Inc. represented approximately 25% of our 2018 consolidated Net sales. 
The loss of, or change in business relationship with, any of these or any other key vendor partners, or the diminished availability 
of their products, including due to backlogs for their products, could reduce the supply and increase the cost of products we sell 
and negatively impact our competitive position.

Additionally, the relocation of key distributors utilized in our purchasing model could increase our need for, and the cost 
of, working capital and have an adverse effect on our business, results of operations or cash flows. Further, the sale, spin-off or 
combination of any of our vendor partners and/or certain of their business units, including any such sale to or combination with 
a vendor with whom we do not currently have a commercial relationship or whose products we do not sell, could have an adverse 
impact on our business, results of operations or cash flows. 

Our sales are dependent on continued innovations in hardware, software and services offerings by our vendor partners and 
the competitiveness of their offerings, and our ability to partner with new and emerging technology providers. 

The technology industry is characterized by rapid innovation and the frequent introduction of new and enhanced hardware, 
software and services offerings, such as cloud-based solutions, including Software as a Service ("SaaS"), Infrastructure as a Service 
("IaaS") and Platform as a Service ("PaaS"); Device as a Service ("DaaS"); the Internet of Things ("IoT"); and Artificial Intelligence. 
We have been and will continue to be dependent on innovations in hardware, software and services offerings, as well as the 
acceptance of those innovations by customers. Also, customers may delay spending while they evaluate new technologies. A 
decrease in the rate of innovation, a lack of acceptance of innovations by our customers or delays in technology spending by our 
customers, could have an adverse effect on our business, results of operations or cash flows.

In addition, if we are unable to keep up with changes in technology and new hardware, software and services offerings, 
for example by providing the appropriate training to our account managers, sales technology specialists and engineers to enable 
them to effectively sell and deliver such new offerings to customers, our business, results of operations or cash flows could be 
adversely affected.

We also are dependent upon our vendor partners for the development and marketing of hardware, software and services 
to compete effectively with hardware, software and services of vendors whose products and services we do not currently offer or 
that we are not authorized to offer in one or more customer channels. Our success is dependent on our ability to develop relationships 
with and sell hardware, software and services from new emerging vendors and vendors that we have not historically represented 
in the marketplace. To the extent that a vendor's offering that is highly in demand is not available to us for resale in one or more 
customer channels, and there is not a competitive offering from another vendor that we are authorized to sell in such customer 
channels, or if we are unable to develop relationships with new technology providers or companies that we have not historically 
represented, our business, results of operations or cash flows could be adversely impacted. 

Substantial competition could reduce our market share and significantly harm our financial performance.

Our current competition includes: 

resellers,  such  as  Computacenter,  Connection,  Dimension  Data,  ePlus,  Insight  Enterprises,  PCM,  Presidio,  SCC, 
Softchoice, World Wide Technology and many smaller resellers;

manufacturers who sell directly to customers, such as Adobe, Apple, Dell, HP Inc. and Hewlett Packard Enterprise;

Table of Contents

We expect the competitive landscape to continue to evolve as new technologies and consumption models are developed, 
such as cloud-based and other "as a service" solutions, hyper-converged infrastructure and embedded software solutions. While 
innovation can help our business as it creates new offerings for us to sell, it can also disrupt our business model and create new 
and stronger competitors. For instance, while cloud-based solutions present an opportunity for us, cloud-based solutions and 
technology solutions as a service could increase the amount of sales directly to customers rather than through solutions providers 
like us, or could reduce the amount of hardware we sell. In addition, some of our hardware and software vendor partners sell, and 
could intensify their efforts to sell, their products directly to our customers. Moreover, traditional OEMs have increased their 
services capabilities through mergers and acquisitions with service providers, which could potentially increase competition in the 
market  to  provide  comprehensive  technology  solutions  to  customers.  If  we  are  unable  to  effectively  respond  to  the  evolving 
competitive landscape, our business, results of operations or cash flows could be adversely impacted. 

We focus on offering a high level of service to gain new customers and retain existing customers. To the extent we face 
increased competition to gain and retain customers, we may be required to reduce prices, increase advertising expenditures or take 
other actions which could adversely affect our business, results of operations or cash flows. Additionally, some of our competitors 
may reduce their prices in an attempt to stimulate sales, which may require us to reduce prices. This would require us to sell a 
greater number of products to achieve the same level of Net sales and Gross profit. If such a reduction in prices occurs and we 
are unable to attract new customers and sell increased quantities of products, our sales growth and profitability could be adversely 
affected.

The success of our business depends on the continuing development, maintenance and operation of our information technology 
systems. 

Our success is dependent on the accuracy, proper utilization and continuing development of our information technology 
systems, including our business systems, such as our sales, customer management, financial and accounting, marketing, purchasing, 
warehouse management, e-commerce and mobile systems, as well as our operational platforms, including voice and data networks 
and power systems. The quality and our utilization of the information generated by our information technology systems, and our 
success in implementing new systems and upgrades, affects, among other things, our ability to: 

• 

• 

• 

• 

conduct business with our customers, including delivering services and solutions to them;

manage our inventory and accounts receivable and accounts payable;

purchase,  sell,  ship  and  invoice  our  hardware  and  software  products  and  provide  and  invoice  our  services 
efficiently and on a timely basis; and

maintain our cost-efficient operating model while scaling our business.

The integrity of our information technology systems is vulnerable to disruption due to forces beyond our control. While 
we have taken steps to protect our information technology systems from a variety of threats, both internal and external, and from 
human error, there can be no guarantee that those steps will be effective. Furthermore, although we have redundant systems at a 
separate location to back up our primary systems, there can be no assurance that these redundant systems will operate properly if 
and when required. Any disruption to or infiltration of our information technology systems could significantly harm our business 
and results of operations.

Breaches  of  data  security  and  the  failure  to  protect  our  information  technology  systems  from  cybersecurity  threats  could 
adversely impact our business. 

Our business involves the storage and transmission of proprietary information and sensitive or confidential data, including 
personal information of coworkers, customers and others. In addition, we operate data centers for our customers that host their 
technology infrastructure and may store and transmit both business-critical data and confidential information. In connection with 
our services business, some of our coworkers have access to our customers' confidential data and other information. We have 
privacy and data security policies in place that are designed to prevent security breaches; however, as newer technologies evolve, 
and the portfolio of the service providers we share confidential information with grows, we could be exposed to increased risks 
from breaches in security, including those from human error, negligence or mismanagement or from illegal or fraudulent acts, 
such as cyberattacks. The evolving nature of threats to data security, in light of new and sophisticated methods used by criminals 
and cyberterrorists, including computer viruses, malware, phishing, misrepresentation, social engineering and forgery, make it 
increasingly challenging to anticipate and adequately mitigate these risks. 

Breaches in security could expose us, our supply chain, our customers or other individuals to significant disruptions, a 
risk of public disclosure, loss or misuse of this information. Security breaches could result in legal claims or proceedings, liability 
or regulatory penalties under laws protecting the privacy of personal information, as well as the loss of existing or potential

customers and damage to our brand and reputation. Moreover, media or other reports of perceived vulnerabilities in our network 
security  or  perceived  lack  of  security  within  our  environment,  even  if  inaccurate,  could  adversely  impact  our  reputation  and 
materially impact our business. The cost and operational consequences of implementing further data protection measures could 
be significant. Such breaches, costs and consequences could adversely affect our business, results of operations or cash flows. 

The failure to comply with our public sector contracts or applicable laws and regulations could result in, among other things, 
termination, fines or other liabilities, and changes in procurement regulations could adversely impact our business, results of 
operations or cash flows.

Revenues from our public sector customers are derived from sales to governmental entities, educational institutions and 
healthcare customers through various contracts and open market sales of products and services. Sales to public sector customers 
are highly regulated. Noncompliance with contract provisions, government procurement regulations or other applicable laws or 
regulations (including the False Claims Act, the Medicare and Medicaid Anti-Kickback Statute or similar laws of the jurisdictions 
for our business activities outside of the US) or security clearance and confidentiality requirements could result in civil, criminal 
and administrative liability, including substantial monetary fines or damages, termination of government contracts or other public 
sector customer contracts, and suspension, debarment or ineligibility from doing business with governmental entities or other 
customers in the public sector. In addition, contracts in the public sector are generally terminable at any time for convenience of 
the contracting agency or group purchasing organization ("GPO") or upon default. Furthermore, our inability to enter into or retain 
contracts with GPOs may threaten our ability to sell to customers in those GPOs and compete effectively. The effect of any of 
these possible actions or failures could adversely affect our business, results of operations or cash flows. In addition, the adoption 
of new or modified procurement regulations and other requirements may increase our compliance costs and reduce our gross 
margins, which could have a negative effect on our business, results of operations or cash flows. 

If we or our third-party service providers fail to provide high-quality services to our customers, our reputation, business, results 
of operations or cash flows could be adversely affected.

Our service offerings include field services, managed services, warranties, configuration services, partner services and 
telecom services. Additionally, we deliver and manage mission critical software, systems and network solutions for our customers. 
We also offer certain services, such as implementation and installation services and repair services, to our customers through 
various third-party service providers engaged to perform these services on our behalf. If we or our third-party service providers 
fail to provide high-quality services to our customers or such services result in a disruption of our customers' businesses, this 
could, among other things, result in legal claims and proceedings and liability for us. Moreover, as we expand our services and 
solutions business and provide increasingly complex services and solutions, we may be exposed to additional operational, regulatory 
and other risks. We also could incur liability for failure to comply with the rules and regulations applicable to the new services 
and solutions we provide to our customers. If any of the foregoing were to occur, our reputation with our customers, our brand 
and our business, results of operations or cash flows could be adversely affected.

If we lose any of our key personnel, or are unable to attract and retain the talent required for our business, our business could 
be disrupted and our financial performance could suffer. 

Our success is heavily dependent upon our ability to attract, develop, engage and retain key personnel to manage and 

grow our business, including our key executive, management, sales, services and technical coworkers. 

Our future success will depend to a significant extent on the efforts of our Chief Executive Officer, as well as the continued 
service and support of our other executive officers. Our future success also will depend on our ability to retain and motivate our 
customer-facing coworkers,  who have been given critical CDW knowledge regarding, and the opportunity to develop strong 
relationships with, many of our customers. In addition, as we seek to expand our offerings of value-added services and solutions, 
our success will even more heavily depend on attracting and retaining highly skilled technology specialists and engineers, for 
whom the market is extremely competitive. 

If we are unable to attract, develop, engage and retain key personnel, our relationships with our vendor partners and 
customers and our ability to expand our offerings of value-added services and solutions could be adversely affected. Moreover, 
if we are unable to continue to train our sales, services and technical personnel effectively to meet the rapidly changing technology 
needs of our customers, the overall quality and efficiency of such personnel could decrease. Such consequences could adversely 
affect our business, results of operations or cash flows.

The interruption of the flow of products from suppliers could disrupt our supply chain.

Our business depends on the timely supply of products in order to meet the demands of our customers. Manufacturing 
interruptions or delays, including as a result of the financial instability or bankruptcy of manufacturers, significant labor disputes 
such as strikes, natural disasters or other adverse occurrences affecting any of our suppliers' facilities, could disrupt our supply 
chain. Suppliers may also fail to accurately forecast customer demand, or may be unable to manufacture sufficient quantities of 
product to meet customer demand, resulting in the reduced supply of product available to us.  

Our supply chain is also exposed to risks related to international operations. While we purchase our products primarily 
in the markets we serve (for example, products for US customers are sourced in the US), our vendor partners manufacture or 
purchase a significant portion of the products we sell outside of the US, primarily in Asia. Political, social or economic instability 
in Asia, or in other regions in which our vendor partners purchase or manufacture the products we sell, could cause disruptions 
in trade, including exports to the US. Other events related to international operations that could cause disruptions to our supply 
chain include: 

• 

• 

• 

• 

the imposition of additional trade law provisions or regulations, including the adoption or expansion of trade restrictions;

the imposition of additional duties, tariffs and other charges on imports and exports, including any resulting retaliatory 
tariffs or charges and any reductions in the production of products subject to such tariffs and charges;

foreign currency fluctuations; and

restrictions on the transfer of funds.

We cannot predict whether the countries in which the products we sell, or any components of those products, are purchased 
or manufactured will be subject to new or additional trade restrictions or sanctions imposed by the US or foreign governments, 
including the likelihood, type or effect of any such restrictions. Trade restrictions, including new or increased tariffs or quotas, 
embargoes, sanctions, safeguards and customs restrictions against the products we sell, could increase the cost or reduce the supply 
of product available to us and adversely affect our business, results of operations or cash flows. In addition, our exports are subject 
to regulations, some of which may be inconsistent, and noncompliance with these requirements could have a negative effect on 
our business, results of operations or cash flows. 

A natural disaster or other adverse occurrence at one of our primary facilities or customer data centers could damage our 
business. 

We have two warehouse and distribution facilities in the US and one in the UK. If the warehouse and distribution equipment 
at one of our distribution centers were to be seriously damaged by a natural disaster or other adverse occurrence, we could utilize 
another distribution center or third-party distributors to ship products to our customers. However, this may not be sufficient to 
avoid interruptions in our service and may not enable us to meet all of the needs of our customers and would cause us to incur 
incremental operating costs. In addition, we operate three customer data centers and numerous sales offices which may contain 
both business-critical data and confidential information of our customers. A natural disaster or other adverse occurrence at any of 
the customer data centers or at any of our major sales offices could negatively impact our business, results of operations or cash 
flows. 

Increases in the cost of commercial delivery services or disruptions of those services could adversely impact our business.

We generally ship hardware products to our customers by FedEx, United Parcel Service and other commercial delivery 
services and invoice customers for delivery charges. If we are unable to pass on to our customers future increases in the cost of 
commercial delivery services (including those that may result from an increase in fuel or personnel costs), our profitability could 
be adversely affected. Additionally, strikes, inclement weather, natural disasters or other service interruptions by such shippers 
could adversely affect our ability to deliver or receive products on a timely basis.

We are exposed to accounts receivable and inventory risks. 

We extend credit to our customers for a significant portion of our Net sales, typically on 30-day payment terms. We are 
subject to the risk that our customers may not pay for the products they have purchased, or may pay at a slower rate than we have 
historically experienced. This risk is heightened during periods of global or industry-specific economic downturn or uncertainty, 
during periods of rising interest rates or, in the case of public sector customers, during periods of budget constraints. Significant 
failures of customers to timely pay all amounts due to us could adversely affect our business, results of operations or cash flows.

We are also exposed to inventory risks as a result of the rapid technological changes that affect the market and pricing 
for the products we sell. We seek to minimize our inventory exposure through a variety of inventory management procedures and 

13

 
 
Table of Contents

policies, including our rapid-turn inventory model, as well as vendor price protection and product return programs. However, if 
we were unable to maintain our rapid-turn inventory model, if there were unforeseen product developments that created more 
rapid obsolescence or if our vendor partners were to change their terms and conditions, our inventory risks could increase. We 
also from time to time take advantage of cost savings associated with certain opportunistic bulk inventory purchases offered by 
our vendor partners or we may decide to carry high inventory levels of certain products that have limited or no return privileges 
due to customer demand or request or to manage supply chain interruptions. If we purchase inventory in anticipation of customer 
demand that does not materialize, or if customers reduce or delay orders, we would be exposed to an increased risk of inventory 
obsolescence.

We could be exposed to additional risks if we continue to make strategic investments or acquisitions or enter into alliances.

We may continue to pursue transactions, including strategic investments, acquisitions or alliances, in an effort to extend 
or complement our existing business. These types of transactions involve numerous business risks, including finding suitable 
transaction partners and negotiating terms that are acceptable to us, the diversion of management's attention from other business 
concerns, extending our product or service offerings into areas in which we have limited experience, entering into new geographic 
markets, the potential loss of key coworkers or business relationships and successfully integrating acquired businesses. There can 
be no assurance that the intended benefits of our investments, acquisitions and alliances will be realized, or that those benefits 
will offset these numerous risks or other unforeseen factors, any of which could adversely affect our business, results of operations 
or cash flows. 

In addition, our financial results could be adversely affected by financial adjustments required by generally accepted 
accounting principles in the United States of America ("GAAP") in connection with these types of transactions where significant 
goodwill or intangible assets are recorded. To the extent the value of goodwill or identifiable intangible assets with indefinite lives 
becomes impaired, we may be required to incur material charges relating to the impairment of those assets.

Our future operating results may fluctuate significantly, which may result in volatility in the market price of our stock and 
could impact our ability to operate our business effectively.

We may experience significant variations in our future quarterly results of operations. These fluctuations may cause the 
market price of our common stock to be volatile and may result from many factors, including the condition of the technology 
industry in general, shifts in demand and pricing for hardware, software and services and the introduction of new products or 
upgrades. 

Our operating results are also highly dependent on our level of Gross profit as a percentage of Net sales. Our Gross profit 
percentage fluctuates due to numerous factors, some of which may be outside of our control, including general macroeconomic 
conditions; pricing pressures; changes in product costs from our vendor partners; the availability of price protection, purchase 
discounts and incentive programs from our vendor partners; changes in product, order size and customer mix; the risk of some 
items in our inventory becoming obsolete; increases in delivery costs that we cannot pass on to customers; and general market 
and competitive conditions. 

In addition, our cost structure is based, in part, on anticipated sales and gross margins. Therefore, we may not be able to 
adjust our cost structure quickly enough to compensate for any unexpected sales or gross margin shortfall, and any such inability 
could have an adverse effect on our business, results of operations or cash flows. 

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

Our exposure to fluctuations in foreign currency rates results primarily from the translation exposure associated with the 
preparation of our Consolidated Financial Statements. While our Consolidated Financial Statements are reported in US dollars, 
the financial statements of our subsidiaries outside the US are prepared using the local currency as the functional currency and 
translated into US dollars. As a result, fluctuations in the exchange rate of the US dollar relative to the local currencies of our 
international subsidiaries, particularly the British pound and the Canadian dollar, could cause fluctuations in our reported results 
of operations. We also have foreign currency exposure to the extent sales and purchases are not denominated in a subsidiary's 
functional currency, which could have an adverse effect on our business, results of operations or cash flows.

We are exposed to risks from legal proceedings and audits, which may result in substantial costs and expenses or interruption 
of our normal business operations. 

We are party to various legal proceedings that arise in the ordinary course of our business, which include commercial, 

employment, tort and other litigation. 

We are subject to intellectual property infringement claims against us in the ordinary course of our business, either because 
of the products and services we sell or the business systems and processes we use to sell such products and services, in the form 
14

Table of Contents

of cease-and-desist letters, licensing inquiries, lawsuits and other communications and demands. In our industry, such intellectual 
property claims have become more frequent as the complexity of technological products and the intensity of competition in our 
industry have increased. Increasingly, many of these assertions are brought by non-practicing entities whose principal business 
model is to secure patent licensing revenue, but we may also be subject to demands from inventors, competitors or other patent 
holders who may seek licensing revenue, lost profits and/or an injunction preventing us from engaging in certain activities, including 
selling certain products or services. 

We also are subject to proceedings, investigations and audits by federal, state, international, national, provincial and local 
authorities, including as a result of our significant sales to governmental entities. We also are subject to audits by various vendor 
partners and large customers, including government agencies, relating to purchases and sales under various contracts. In addition, 
we are subject to indemnification claims under various contracts. 

Current and future litigation, infringement claims, governmental proceedings and investigations, audits or indemnification 
claims that we face may result in substantial costs and expenses and significantly divert the attention of our management regardless 
of the outcome. In addition, these matters could lead to increased costs or interruptions of our normal business operations. Litigation, 
infringement claims, governmental proceedings and investigations, audits or indemnification claims involve uncertainties and the 
eventual outcome of any such matter could adversely affect our business, results of operations or cash flows. 

Failure to comply with complex and evolving laws and regulations applicable to our operations could adversely impact our 
business, results of operations or cash flows.

Our operations are subject to numerous complex federal, state, provincial, local and foreign laws and regulations in a 
number of areas, including labor and employment, advertising, e-commerce, tax, trade, import and export requirements, economic 
and trade sanctions, anti-corruption, data privacy requirements (including those under the European Union General Data Protection 
Regulation), anti-competition, environmental and health and safety. The evaluation of, and compliance with these laws, regulations 
and similar requirements may be onerous and expensive, and these laws and regulations may have other adverse impacts on our 
business, results of operations or cash flows. Furthermore, these laws and regulations are evolving and may be inconsistent from 
jurisdiction to jurisdiction, further increasing the cost of compliance and doing business, and the risk of noncompliance. 

We have implemented policies and procedures designed to help ensure compliance with applicable laws and regulations, 
but there can be no guarantee against coworkers, contractors or agents violating such laws and regulations or our policies and 
procedures. 

As a public company, we also are subject to increasingly complex public disclosure, corporate governance and accounting 

requirements that increase compliance costs and require significant management focus. 

Risks Related to Our Indebtedness 

We have a substantial amount of indebtedness, which could have important consequences to our business.

We have a substantial amount of indebtedness. As of December 31, 2018, we had $3.2 billion of total long-term debt 
outstanding, as defined by GAAP, and $429 million of obligations outstanding under our inventory financing agreements, and the 
ability to borrow an additional $1.1 billion under our senior secured asset-based revolving credit loan facility (the "Revolving 
Loan") and an additional £50 million ($64 million at December 31, 2018) under our CDW UK revolving credit facility. Our 
substantial indebtedness could have important consequences, including the following: 

• 

• 

• 

• 

• 

• 

making it more difficult for us to satisfy our obligations with respect to our indebtedness;

requiring us to dedicate a substantial portion of our cash flow from operations to debt service payments on our and our 
subsidiaries' debt, which reduces the funds available for working capital, capital expenditures, acquisitions and other 
general corporate purposes;

requiring us to comply with restrictive covenants in our senior credit facilities and indentures, which limit the manner in 
which we conduct our business;

making  it  more  difficult  for  us  to  obtain  vendor  financing  from  our  vendor  partners,  including  original  equipment 
manufacturers and software publishers;

limiting our flexibility in planning for, or reacting to, changes in the industry in which we operate;

placing us at a competitive disadvantage compared to any of our less-leveraged competitors;

15

Table of Contents

• 

• 

increasing our vulnerability to both general and industry-specific adverse economic conditions; and

limiting our ability to obtain additional debt or equity financing to fund future working capital, capital expenditures, 
acquisitions or other general corporate requirements and increasing our cost of borrowing. 

Restrictive covenants under our senior credit facilities and, to a lesser degree, our indentures may adversely affect our operations 
and liquidity. 

Our senior credit facilities and, to a lesser degree, our indentures contain, and any future indebtedness of ours may contain, 

various covenants that limit our ability to, among other things: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

incur or guarantee additional debt;

pay  dividends  or  make  distributions  to  holders  of  our  capital  stock  or  to  make  certain  other  restricted  payments  or 
investments;

repurchase or redeem capital stock;

make loans, capital expenditures or investments or acquisitions;

receive dividends or other payments from our subsidiaries;

enter into transactions with affiliates;

pledge our assets as collateral;

merge or consolidate with other companies or transfer all or substantially all of our assets; 

transfer or sell assets, including capital stock of subsidiaries; and

prepay, repurchase or redeem debt.

As a result of these covenants, we are limited in the manner in which we conduct our business and we may be unable to 
engage in favorable business activities or finance future operations or capital needs. A breach of any of these covenants or any of 
the other restrictive covenants would result in a default under our senior credit facilities. Upon the occurrence of an event of default 
under our senior credit facilities, the lenders:

• 

• 

• 

will not be required to lend any additional amounts to us;

could elect to declare all borrowings outstanding thereunder, together with accrued and unpaid interest and fees, to be 
due and payable; or 

could require us to apply all of our available cash to repay these borrowings.

The acceleration of amounts outstanding under our senior credit facilities would likely trigger an event of default under 

our existing indentures.

If we were unable to repay those amounts, the lenders under our senior credit facilities could proceed against the collateral 
granted to them to secure our borrowings thereunder. We have pledged a significant portion of our assets as collateral under our 
senior credit facilities. If the lenders under our senior credit facilities accelerate the repayment of borrowings, we cannot assure 
you that we will have sufficient assets to repay our senior credit facilities and our other indebtedness or the ability to borrow 
sufficient funds to refinance such indebtedness. Even if we were able to obtain new financing, it may not be on commercially 
reasonable terms, or terms that are acceptable to us.

In addition, under our Revolving Loan, we are permitted to borrow an aggregate amount of up to $1.1 billion. However, 
our ability to borrow under our Revolving Loan is limited by a borrowing base and a liquidity condition. The borrowing base at 
any time equals the sum of up to 85% of CDW LLC and its subsidiary guarantors' eligible accounts receivable (net of accounts 
reserves) (up to 30% of such eligible accounts receivable which can consist of federal government accounts receivable) plus the 
lesser of (i) 75% of CDW LLC and its subsidiary guarantors' eligible inventory (valued at cost and net of inventory reserves) and 
(ii) the product of 85% multiplied by the net orderly liquidation value percentage multiplied by eligible inventory (valued at cost 
and net of inventory reserves), less reserves (other than accounts reserves and inventory reserves). The borrowing base in effect 
as of December 31, 2018 was $1.8 billion and, therefore, did not restrict our ability to borrow under our Revolving Loan as of 
that date. 

16

Table of Contents

Our ability to borrow under our Revolving Loan is also limited by a minimum liquidity condition, which provides that, 
if excess cash availability is less than the lesser of (i) $125 million and (ii) the greater of (A) 10% of the borrowing base and (B) 
$100 million, the lenders are not required to lend any additional amounts under our Revolving Loan unless the consolidated fixed 
charge coverage ratio (as defined in the credit agreement for our Revolving Loan) is at least 1.00 to 1.00. It is an event of default 
under our Revolving Loan if our excess cash availability and consolidated fixed charge coverage ratio remain below such levels 
for a period of five or more consecutive business days. Moreover, our Revolving Loan provides discretion to the agent bank acting 
on behalf of the lenders to impose additional availability reserves, which could materially impair the amount of borrowings that 
would otherwise be available to us. We cannot assure you that the agent bank will not impose such reserves or, were it to do so, 
that the resulting impact of this action would not materially and adversely impair our liquidity.

We will be required to generate sufficient cash to service our indebtedness and, if not successful, we may be forced to take other 
actions to satisfy our obligations under our indebtedness.

Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial and operating 
performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other 
factors beyond our control. Our outstanding long-term debt will impose significant cash interest payment obligations on us and, 
accordingly, we will have to generate significant cash flow from operating activities to fund our debt service obligations. We 
cannot assure you that we will maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, 
premium, if any, and interest on our indebtedness. See "Management's Discussion and Analysis of Financial Condition and Results 
of Operations-Liquidity and Capital Resources" included elsewhere in this report.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce 
or  delay  capital  expenditures,  sell  assets  or  operations,  seek  additional  debt  or  equity  capital,  restructure  or  refinance  our 
indebtedness, or revise or delay our strategic plan. We cannot assure you that we would be able to take any of these actions on 
terms that are favorable to us or at all, that these actions would be successful and permit us to meet our scheduled debt service 
obligations or satisfy our capital requirements, or that these actions would be permitted under the terms of our existing or future 
debt agreements, including our senior credit facilities and indentures. In the absence of such operating results and resources, we 
could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service 
and other obligations. Our senior credit facilities restrict our ability to dispose of assets and use the proceeds from the disposition. 
We may not be able to consummate those dispositions or to obtain the proceeds which we could realize from them and these 
proceeds may not be adequate to meet any debt service obligations then due. 

If we cannot make scheduled payments on our debt, we will be in default and, as a result:

our debt holders could declare all outstanding principal and interest to be due and payable;

the lenders under our senior credit facilities could foreclose against the assets securing the borrowings from them and 
the lenders under our Revolving Loan and CDW UK revolving credit facility could terminate their commitments to lend 
us money; and

we could be forced into bankruptcy or liquidation. 

• 

• 

• 

Despite our indebtedness levels, we and our subsidiaries may be able to incur substantially more debt, including secured debt. 
This could further increase the risks associated with our leverage. 

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of our senior 
credit facilities and indentures do not fully prohibit us or our subsidiaries from doing so. To the extent that we incur additional 
indebtedness, the risks associated with our substantial indebtedness described above, including our possible inability to service 
our debt, will increase. As of December 31, 2018, we had $1.1 billion available for additional borrowing under our Revolving 
Loan after taking into account borrowing base limitations (net of $1 million of issued and undrawn letters of credit and $393 
million of reserves related to our floorplan sub-facility) and an additional £50 million ($64 million at December 31, 2018) available 
under our CDW UK revolving credit facility.

Variable  rate  indebtedness  subjects  us  to  interest  rate  risk,  which  could  cause  our  debt  service  obligations  to  increase 
significantly. 

Certain of our borrowings, primarily borrowings under our senior credit facilities, are at variable rates of interest and 
expose us to interest rate risk. As of December 31, 2018, we had $1.5 billion of variable rate debt outstanding. If interest rates 
increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained 
the same, and our net income would decrease. Although we have entered into interest rate cap agreements on our term loan facility 

17

Table of Contents

to reduce interest rate volatility, we cannot assure you we will be able to enter into interest rate cap agreements in the future on 
acceptable terms or that such caps or the caps we have in place now will be effective. 

Risks Related to Ownership of Our Common Stock

Our common stock price may be volatile and may decline regardless of our operating performance, and holders of our common 
stock could lose a significant portion of their investment.

The market price for our common stock may be volatile. Our stockholders may not be able to resell their shares of common 
stock at or above the price at which they purchased such shares, due to fluctuations in the market price of our common stock, 
which may be caused by a number of factors, many of which we cannot control, including the risk factors described in this Annual 
Report on Form 10-K and the following:

• 

• 

• 

• 

• 

• 

• 

changes in financial estimates by any securities analysts who follow our common stock, our failure to meet these estimates 
or failure of securities analysts to maintain coverage of our common stock;

downgrades by any securities analysts who follow our common stock;

future sales of our common stock by our officers, directors and significant stockholders;

market conditions or trends in our industry or the economy as a whole;

investors' perceptions of our prospects;

announcements by us or our competitors of significant contracts, acquisitions, joint ventures or capital commitments; 
and

changes in key personnel.

In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue 
to affect the market prices of equity securities of many companies, including companies in our industry. In the past, securities 
class action litigation has followed periods of market volatility. If we were involved in securities litigation, we could incur substantial 
costs, and our resources and the attention of management could be diverted from our business.

In the future, we may also issue our securities in connection with investments or acquisitions. The number of shares of 
our common stock issued in connection with an investment or acquisition could constitute a material portion of our then-outstanding 
shares of our common stock and depress our stock price.

Anti-takeover provisions in our charter documents and Delaware law might discourage or delay acquisition attempts for us 
that you might consider favorable.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may 

make the acquisition of the Company more difficult without the approval of our Board of Directors. These provisions:

• 

• 

• 

• 

• 

• 

authorize the issuance of undesignated preferred stock, the terms of which may be established and the shares of which 
may be issued without stockholder approval, and which may include super voting, special approval, dividend, or other 
rights or preferences superior to the rights of the holders of common stock;

establish a classified Board of Directors until the 2021 annual meeting of stockholders, so that not all members of our 
Board of Directors are elected at one time;

generally prohibit stockholder action by written consent, requiring all stockholder actions be taken at a meeting of our 
stockholders;

provide that special meetings of the stockholders can only be called by or at the direction of our Board of Directors 
pursuant to a written resolution adopted by the affirmative vote of the majority of the total number of directors that the 
Company would have if there were no vacancies;

establish advance notice requirements for nominations for elections to our Board of Directors or for proposing matters 
that can be acted upon by stockholders at stockholder meetings; and

provide that our Board of Directors is expressly authorized to make, alter or repeal our amended and restated bylaws.

18

Table of Contents

Our amended and restated certificate of incorporation also contains a provision that provides us with protections similar 
to Section 203 of the Delaware General Corporation Law, and will prevent us from engaging in a business combination with a 
person who acquires at least 15% of our common stock for a period of three years from the date such person acquired such common 
stock, unless board or stockholder approval is obtained prior to the acquisition. These anti-takeover provisions and other provisions 
under Delaware law could discourage, delay or prevent a transaction involving a change in control of the Company, even if doing 
so would benefit our stockholders. These provisions could also discourage proxy contests and make it more difficult for our 
stockholders to elect directors of their choosing and to cause us to take other corporate actions our stockholders desire.

We cannot assure you that we will continue to pay dividends on our common stock or repurchase any of our common stock 
under our share repurchase program, and our indebtedness and certain tax considerations could limit our ability to continue 
to pay dividends on, or make share repurchases of, our common stock. If we do not continue to pay dividends, you may not 
receive any return on investment unless you are able to sell your common stock for a price greater than your purchase price.

We expect to continue to pay a cash dividend on our common stock, currently at the rate of $0.295 per share per quarter, 
or $1.18 per share per annum. However, any determination to pay dividends in the future will be at the discretion of our Board of 
Directors. Any determination to pay dividends on, or repurchase, shares of our common stock in the future will depend upon our 
results  of  operations,  financial  condition,  business  prospects,  capital  requirements,  contractual  restrictions,  any  potential 
indebtedness we may incur, restrictions imposed by applicable law, tax considerations and other factors our Board of Directors 
deems relevant. In addition, our ability to pay dividends on, or repurchase, shares of our common stock will be limited by restrictions 
on our ability to pay dividends or make distributions to our stockholders and on the ability of our subsidiaries to pay dividends or 
make distributions to us, in each case, under the terms of our current and any future agreements governing our indebtedness. There 
can be no assurance that we will continue to pay a dividend at the current rate or at all or that we will repurchase shares of our 
common stock. If we do not pay dividends in the future, realization of a gain on your investment will depend entirely on the 
appreciation of the price of our common stock, which may never occur. 

We are a holding company and rely on dividends, distributions and other payments, advances and transfers of funds from our 
subsidiaries to meet our obligations.

We are a holding company that does not conduct any business operations of our own. As a result, we are largely dependent 
upon cash dividends and distributions and other transfers from our subsidiaries to meet our obligations. The agreements governing 
the indebtedness of our subsidiaries impose restrictions on our subsidiaries' ability to pay dividends or other distributions to us. 
The deterioration of the earnings from, or other available assets of, our subsidiaries for any reason could also limit or impair their 
ability to pay dividends or other distributions to us.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

As of December 31, 2018, we owned or leased a total of 2.2 million square feet of space, primarily in the US, Canada 
and UK. We own two properties: a 513,000 square foot distribution center in North Las Vegas, Nevada, and a combined office 
and a 442,000 square foot distribution center in Vernon Hills, Illinois. In addition, we conduct sales, services and administrative 
activities  in  various  leased  locations  primarily  in  the  US,  Canada  and  UK,  including  data  centers  in  Madison,  Wisconsin, 
Minneapolis, Minnesota and the UK.

We believe our facilities are well maintained, suitable for our business and occupy sufficient space to meet our operating 
needs. As part of our normal business, we regularly evaluate sales center performance and site suitability. Leases covering our 
currently occupied leased properties expire at varying dates, generally within the next ten years. We anticipate no difficulty in 
retaining  occupancy  through  lease  renewals,  month-to-month  occupancy  or  replacing  the  leased  properties  with  equivalent 
properties. We believe that suitable additional or substitute leased properties will be available as required. 

Item 3. Legal Proceedings 

We are party to various legal proceedings that arise in the ordinary course of our business, which include commercial, 
intellectual property, employment, tort and other litigation matters. We are also subject to audit by federal, state, international, 
national,  provincial  and  local  authorities,  and  by  various  partners,  group  purchasing  organizations  and  customers,  including 
government agencies, relating to purchases and sales under various contracts. In addition, we are subject to indemnification claims 
under various contracts. From time to time, certain of our customers file voluntary petitions for reorganization or liquidation under 
the US bankruptcy laws or similar laws of the jurisdictions for our business activities outside of the US. In such cases, certain pre-
petition payments received by us could be considered preference items and subject to return to the bankruptcy administrator.

As of December 31, 2018, we do not believe that there is a reasonable possibility that any material loss exceeding the 
amounts already recognized for these proceedings and matters, if any, has been incurred. However, the ultimate resolutions of 
these proceedings and matters are inherently unpredictable. As such, our financial condition and results of operations could be 
adversely affected in any particular period by the unfavorable resolution of one or more of these proceedings or matters.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information

Our common stock has been listed on the Nasdaq Global Select Market since June 27, 2013 under the symbol "CDW." 

Holders

As of February 22, 2019, there were 19 holders of record of our common stock. The number of beneficial stockholders 
is substantially greater than the number of holders of record because a portion of our common stock is held through brokerage 
firms.

Dividends

On February 7, 2019, we announced that our Board of Directors declared a quarterly cash dividend on our common stock 
of $0.295 per share. The dividend will be paid on March 12, 2019 to all stockholders of record as of the close of business on 
February 25, 2019. 

We expect to continue to pay quarterly cash dividends on our common stock in the future, but such payments remain at 
the discretion of our Board of Directors and will depend upon our results of operations, financial condition, business prospects, 
capital requirements, contractual restrictions, any potential indebtedness we may incur, restrictions imposed by applicable law, 
tax considerations and other factors that our Board of Directors deems relevant. In addition, our ability to pay dividends on our 
common stock will be limited by restrictions on our ability to pay dividends or make distributions to our stockholders and on the 
ability of our subsidiaries to pay dividends or make distributions to us, in each case, under the terms of our current and any future 
agreements governing our indebtedness. For a discussion of our cash resources and needs and restrictions on our ability to pay 
dividends, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital 
Resources" included elsewhere in this report. For additional discussion of restrictions on our ability to pay dividends, see Note 9
(Long-Term Debt) to the accompanying Consolidated Financial Statements.

Issuer Purchases of Equity Securities

On August 3, 2017, we announced that our Board of Directors authorized a $750 million increase to our share repurchase 
program under which we may repurchase shares of our common stock in the open market through privately negotiated or other 
transactions, depending on share price, market conditions and other factors. On February 7, 2019, we announced that our Board 
of Directors authorized a $1.0 billion increase to our share repurchase program.

Amounts for 2017 and 2016 have been adjusted to reflect the adoption of Topic 606.

Includes the impact of consolidating five months of CDW UK's financial results for the year ended December 31, 2015.

Excludes borrowings of $429 million, $498 million, $580 million, $440 million and $332 million as of December 31, 
2018, 2017, 2016, 2015 and 2014, respectively, under our inventory financing agreements. We do not include these

borrowings in total debt because we have not in the past incurred, and in the future do not expect to incur, any interest 
expense or late fees under these agreements.

EBITDA is defined as consolidated net income before interest expense, income tax expense, depreciation and amortization. 
Adjusted EBITDA, which is a measure defined in our credit agreements, means EBITDA adjusted for certain items which 
are described in the table below. We have included a reconciliation of EBITDA and Adjusted EBITDA in the table below. 
Both EBITDA and Adjusted EBITDA are considered non-GAAP financial measures. Generally, a non-GAAP financial 
measure is a numerical measure of a company's performance or financial position that either excludes or includes amounts 
that are not normally included or excluded in the most directly comparable measure calculated and presented in accordance 
with GAAP. Non-GAAP measures used by management may differ from similar measures used by other companies, 
even when similar terms are used to identify such measures. 

We believe that EBITDA and Adjusted EBITDA provide analysts, investors and management with helpful information 
regarding the underlying operating performance of our business, as they remove the impact of items that management 
believes are not reflective of underlying operating performance. Management uses these measures to evaluate period-
over-period performance as management believes they provide a more comparable measure of the underlying business. 
Additionally, Adjusted EBITDA is a measure in the credit agreement governing our senior secured term loan facility (the 
"Term Loan") used to evaluate our ability to make certain investments, incur additional debt, and make restricted payments, 
such as dividends and share repurchases, as well as whether we are required to make additional principal prepayments 
on the Term Loan beyond the quarterly amortization payments. For further details regarding the Term Loan, see Note 9
(Long-Term Debt) to the accompanying Consolidated Financial Statements.

Amounts for 2017 and 2016 have been adjusted to reflect the adoption of Topic 606.

Includes the impact of consolidating five months of CDW UK's financial results for the year ended December 
31, 2015.

During the years ended December 31, 2017, 2016, 2015 and 2014, we recorded net losses on extinguishments 
of long-term debt. The losses represented the difference between the amount paid upon extinguishment, including 
call premiums and expenses paid to the debt holders and agents, and the net carrying amount of the extinguished 
debt, adjusted for a portion of the unamortized deferred financing costs.

Represents the gain resulting from the remeasurement of our previously held 35% equity investment to fair 
value upon the completion of the acquisition of CDW UK.

Includes other expenses such as payroll taxes on equity-based compensation for the years ended December 31, 
2018 and 2017, expenses related to the acquisition of Scalar Decisions Inc. incurred during 2018, integration 
expenses related to CDW UK during 2017, and the reinstatement of prior year unclaimed property balances as 
a result of a retroactive Illinois state law change enacted during 2017. The year ended December 31, 2016 
includes our share of the settlement payments received from the Dynamic Random Access Memory class actions 
lawsuits and the favorable resolution of a local sales tax matter, offset by integration expenses related to CDW

UK and expenses related to the consolidation of office locations north of Chicago. The year ended December 
31, 2015 includes our 35% share of CDW UK's net loss, which entails our 35% share of an expense related to 
certain equity awards granted by one of the sellers to CDW UK coworkers in July 2015 prior to the acquisition. 
The years ended December 31, 2015 and 2014 also includes certain historical retention costs, expenses related 
to litigation matters, secondary-offering-related expenses and expenses related to the consolidation of office 
locations north of Chicago.

(5) 

Non-GAAP net income excludes, among other things, charges related to the amortization of acquisition-related intangible 
assets, equity-based compensation and the associated tax benefits, acquisition and integration expenses, and gains and 
losses from the extinguishments of long-term debt. Non-GAAP net income is considered a non-GAAP financial measure. 
Generally, a non-GAAP financial measure is a numerical measure of a company's performance or financial position that 
either excludes or includes amounts that are not normally included or excluded in the most directly comparable measure 
calculated and presented in accordance with GAAP. Non-GAAP measures used by management may differ from similar 
measures used by other companies, even when similar terms are used to identify such measures. We believe that non-
GAAP  net  income  provides  analysts,  investors  and  management  with  helpful  information  regarding  the  underlying 
operating performance of our business, as this measure removes the impact of items that management believes are not 
reflective  of  underlying  operating  performance.  Management  uses  this  measure  to  evaluate  period-over-period 
performance as management believes it provides a more comparable measure of the underlying business.

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

Unless otherwise indicated or the context otherwise requires, as used in this "Management's Discussion and Analysis of 
Financial Condition and Results of Operations," the terms "we," "us," "the Company," "our," "CDW" and similar terms refer to 
CDW Corporation and its subsidiaries. "Management's Discussion and Analysis of Financial Condition and Results of Operations" 
should be read in conjunction with the Consolidated Financial Statements and the related notes included elsewhere in this report. 
This discussion contains forward-looking statements that are subject to numerous risks and uncertainties. Actual results may differ 
materially from those contained in any forward-looking statements. See "Forward-Looking Statements" above.

Overview

CDW Corporation is a Fortune 500 company and a leading provider of integrated IT solutions to small, medium and 
large business, and government, education and healthcare customers in the US, the UK and Canada. Our broad array of offerings
ranges from discrete hardware and software products to integrated IT solutions such as mobility, security, data center optimization, 
cloud computing, virtualization and collaboration.

We are technology "agnostic," with a product portfolio including more than 100,000 products and services from more 
than 1,000 leading and emerging brands. Our solutions are delivered in physical, virtual and cloud-based environments through 
over  6,000  customer-facing  coworkers,  including  sellers,  highly-skilled  technology  specialists  and  advanced  service  delivery 
engineers. We are a leading sales channel partner for many original equipment manufacturers ("OEMs"), software publishers and 
cloud providers (collectively, our "vendor partners"), whose products we sell or include in the solutions we offer. We provide our 
vendor partners with a cost-effective way to reach customers and deliver a consistent brand experience through our established 
end-market coverage, technical expertise and extensive customer access. 

We have three reportable segments, Corporate, Small Business and Public. Our Corporate segment primarily serves US 
private sector business customers with more than 250 employees. Our Small Business segment primarily serves US private sector 
business  customers  with  up  to  250  employees.  Our  Public  segment  is  comprised  of  government  agencies  and  education  and 
healthcare institutions in the US. We also have two other operating segments: CDW UK and Canada, each of which do not meet 
the reportable segment quantitative thresholds and, accordingly, are included in an all other category ("Other").

We may sell all or only select products that our vendor partners offer. Each vendor partner agreement provides for specific 
terms and conditions, which may include one or more of the following: product return privileges, price protection policies, purchase 
discounts and vendor incentive programs, such as purchase or sales rebates and cooperative advertising reimbursements. We also 
resell software for major software publishers. Our agreements with software publishers allow the end-user customer to acquire 
software or licensed products and services. In addition to helping our customers determine the best software solutions for their 
needs, we help them manage their software agreements, including warranties and renewals. A significant portion of our advertising 
and marketing expenses are reimbursed through cooperative advertising programs with our vendor partners. These programs are 
at the discretion of our vendor partners and are typically tied to sales or other commitments to be met by us within a specified 
period of time.

Effective January 1, 2018, we adopted the requirements of ASU 2014-09, Revenue from Contracts with Customers, as 

amended ("Topic 606"), utilizing the full retrospective method. Prior period amounts have been adjusted accordingly.

Trends and Key Factors Affecting our Financial Performance

We believe the following key factors may have a meaningful impact on our business performance, influencing our ability 

to generate sales and achieve our targeted financial and operating results:

• 

• 

• 

General economic conditions are a key factor affecting our results as they impact our customers' willingness to spend on 
information technology. This is particularly the case for business customers, as their purchases tend to reflect confidence 
in their business prospects, which are driven by their perceptions of business conditions. Purchasing behavior may be 
different between our Corporate customers and Small Business customers due to their perception of business conditions. 
Additionally, changes in trade policy and product constraints from suppliers could have an adverse impact on our business. 
There continues to be substantial uncertainty regarding the impact of Brexit. Potential adverse consequences of Brexit 
such as global market uncertainty, volatility in currency exchange rates, greater restrictions on imports and exports between 
UK and EU countries and increased regulatory complexities could have a negative impact on our business, financial 
condition and results of operations. To date, CDW UK is not seeing significant changes in the buying behavior of its 
customers even with the uncertainty related to the timing and terms of Brexit. 

Changes in spending policies, budget priorities and funding levels are a key factor influencing the purchasing levels of 
government, healthcare and education customers. A prolonged partial shutdown of the US Government could have an 
adverse impact to our sales to Government customers and sales to our other customers that do business with the areas of 
the  US  Government  affected  by  a  partial  shutdown. Additionally,  a  prolonged  partial  shutdown  could  impact  cash 
collections from contracts with customers who do business with areas of the US Government affected by a partial shutdown.

Technology trends drive customer purchasing behaviors in the market. Current technology trends are focused on delivering 
greater flexibility and efficiency, as well as designing IT securely. These trends are driving customer adoption of solutions 
such as those delivered via cloud, software defined architectures and hybrid on-premise and off-premise combinations, 
as well as the evolution of the IT consumption model to more "as-a-service" offerings, including Device-as-a-Service 
("DaaS") and managed services.

Key Business Metrics

We monitor a number of financial and non-financial measures and ratios on a regular basis in order to track the progress 
of our business and make adjustments as necessary. We believe that the most important of these measures and ratios include average 
daily sales, gross margin, operating margin, Net income, Non-GAAP income before income taxes, Non-GAAP net income, Net 
income per common share, Non-GAAP net income per diluted share, EBITDA, Adjusted EBITDA, Adjusted EBITDA margin, 
free cash flow, return on working capital, Cash and cash equivalents, net working capital, cash conversion cycle (defined to be 
days of sales outstanding in Accounts receivable plus days of supply in Inventory minus days of purchases outstanding in Accounts 
payable, based on a rolling three-month average), debt levels including available credit and leverage ratios, sales per coworker 
and coworker turnover. These measures and ratios are compared to standards or objectives set by management, so that actions can 
be taken, as necessary, in order to achieve the standards and objectives.

In this Form 10-K, we discuss Non-GAAP income before income taxes, Non-GAAP net income, Non-GAAP net income 

per diluted share, EBITDA, Adjusted EBITDA and Adjusted EBITDA margin which are non-GAAP financial measures. 

We believe these measures provide analysts, investors and management with helpful information regarding the underlying 
operating performance of our business, as they remove the impact of items that management believes are not reflective of underlying 
operating performance. Management uses these measures to evaluate period-over-period performance as management believes 
they provide a more comparable measure of the underlying business. Additionally, Adjusted EBITDA is a measure in the credit 
agreement governing our senior secured term loan facility (the "Term Loan") used to evaluate our ability to make certain investments, 
incur additional debt, and make restricted payments, such as dividends and share repurchases, as well as whether we are required 
to  make  additional principal prepayments on  the Term  Loan beyond  the  quarterly amortization payments.  For  further  details 
regarding the Term Loan, see Long-Term Debt and Financing Arrangements within Management's Discussion and Analysis of 
Financial  Condition  and  Results  of  Operations  and  Note  9  (Long-Term  Debt)  to  the  accompanying  Consolidated  Financial 
Statements. For the definitions of Non-GAAP income before income taxes, Non-GAAP net income and Adjusted EBITDA and 
reconciliations to Net income, see "Results of Operations."

Amounts for 2017 have been adjusted to reflect the adoption of Topic 606.

There were 254 selling days for each of the years ended December 31, 2018 and 2017.

Total Net sales for the year ended December 31, 2018 increased $1,408 million, or 9.5%, to $16,241 million, compared 
to $14,833 million for the year ended December 31, 2017. Excluding the impact of foreign currency fluctuations, constant currency 
Net sales growth was 9.2%.

Table of Contents

For the year ended December 31, 2018, sales growth was driven by ongoing focus on client device refresh, the underlying 

demand for solutions and strong growth from our international operations.

Corporate segment Net sales for the year ended December 31, 2018 increased $670 million, or 10.8%, compared to the 
year  ended  December  31,  2017.  Growth  was  primarily  driven  by  client  device  refresh,  as  well  as  continued  success  helping 
customers with solutions, including data center and software.

Small Business segment Net sales for the year ended December 31, 2018 increased by $139 million, or 11.4%, between 

periods. Sales growth was primarily driven by client device refresh.

Public segment Net sales for the year ended December 31, 2018 increased $248 million, or 4.2%, compared to the year 
ended December 31, 2017. Education Net sales increased 6.5%, primarily driven by continued success addressing client device 
and networking needs for both K-12 and Higher Education customers. Net sales in Healthcare increased 7.3%, primarily driven 
by performance in client devices and video as customers moved forward on refresh projects. Net sales to Government customers 
were flat compared to the prior year. Federal Net sales were lower due to the prior year success of meeting the Department of 
Defense mandate to move to new client devices with stronger security features. Federal Net sales were nearly fully offset by the 
success of executing against contracts to State and Local government customers, including meeting public safety needs.

Net sales in Other, which is comprised of results from our UK and Canadian operations, for the year ended December 31, 
2018 increased $351 million, or 22.9%, compared to the year ended December 31, 2017. Both operations had strong growth in 
local currency as we continued to take share in the local markets. In addition, UK growth was driven in part by increased sales 
from referrals for US-based customers. The impact of foreign currency exchange increased Other sales growth by approximately 
270 basis points, primarily due to the favorable translation of the British pound to US dollar.

Gross profit

Gross profit increased $257 million, or 10.5%, to $2,707 million for the year ended December 31, 2018, compared to 
$2,450 million for the year ended December 31, 2017. As a percentage of Net sales, Gross profit margin increased 20 basis points 
to 16.7% for the year ended December 31, 2018. Gross profit margin was impacted by an increase in the mix of revenue recognized 
on a net basis, such as Software as a Service and warranties, as well as improved product margin. This was partially offset by year-
over-year Net sales growth out-pacing the year-over-year growth rate in partner funding.

Gross profit margin may fluctuate based on various factors, including vendor incentive and inventory price protection 
programs, cooperative advertising funds classified as a reduction of cost of sales, product mix, revenue recognized on a net basis, 
pricing strategies, market conditions and other factors.

Selling and administrative expenses

Selling and administrative expenses increased $127 million, or 9.0%, to $1,537 million for the year ended December 31, 
2018, compared to $1,410 million for the year ended December 31, 2017. The increase was driven by higher sales payroll expenses, 
including sales commissions, primarily due to higher Gross profit dollars and higher coworker costs due to higher attainment of 
performance-based compensation.

As a percentage of total Net sales, Selling and administrative expenses remained flat at 9.5% for the year ended December 

31, 2018.

Segment operating income includes the segment's direct operating income, allocations for certain Headquarters costs, 
allocations  for  income  and  expenses  from  logistics  services,  certain  inventory  adjustments  and  volume  rebates  and 
cooperative advertising from vendors.

Includes the financial results for our other operating segments, CDW UK and CDW Canada, which do not meet the

Operating  income  was  $987  million  for  the  year  ended  December 31,  2018,  an  increase  of  $120  million,  or  13.9%, 
compared to $867 million for the year ended December 31, 2017. Operating income increased primarily due to higher Gross profit 
dollars, partially offset by higher sales payroll expenses and higher coworker costs due to higher attainment on performance-based 
compensation. Total operating margin percentage increased 30 basis points to 6.1% for the year ended December 31, 2018, from 
5.8% for the year ended December 31, 2017. The increase was primarily due to Gross profit margin expansion driven by a higher 
mix into revenue recognized on a net basis, as well as improved product margin. Lower intangible asset amortization and equity-
based compensation expense and the associated payroll taxes as a percentage of Net sales, which do not trend in line with sales 
movement, also had a favorable impact on the operating margin percentage. This was partially offset by higher attainment on 
performance-based compensation expense as a percentage of Net sales.

Corporate segment Operating income was $537 million for the year ended December 31, 2018, an increase of $49 million, 
or 10.0%, compared to $488 million for the year ended December 31, 2017. Corporate segment Operating income increased
primarily due to higher Gross profit dollars driven by higher sales, partially offset by higher sales payroll expenses. Corporate 
segment operating margin percentage decreased 10 basis points to 7.8% for the year ended December 31, 2018, from 7.9% for 
the year ended December 31, 2017. The decrease was driven by higher attainment on performance-based compensation expense 
as a percentage of Net sales.

Small Business segment Operating income was $96 million for the year ended December 31, 2018, an increase of $22 
million, or 28.8%, compared to $74 million for the year ended December 31, 2017. Small Business segment Operating income 
increased primarily due to higher Gross profit dollars. Small Business segment operating margin percentage increased 90 basis 
points to 7.0% for the year ended December 31, 2018, from 6.1% for the year ended December 31, 2017. This increase in operating 
margin percentage was primarily driven by a higher mix into revenue recognized on a net basis and the benefit of lower sales 
payroll expenses as a percentage of Net sales. This was partially offset by higher attainment on performance-based compensation 
expense as a percentage of Net sales.

Public segment Operating income was $411 million for the year ended December 31, 2018, an increase of $37 million, 
or 9.7%, compared to $374 million for the year ended December 31, 2017. Public segment Operating income increased primarily 
due to higher Gross profit dollars, partially offset by higher sales payroll expenses. Public segment operating margin percentage 
increased 40 basis points to 6.7% for the year ended December 31, 2018, from 6.3% for the year ended December 31, 2017. This 

32

 
 
 
Table of Contents

increase in operating margin percentage was primarily driven by a higher mix into revenue recognized on a net basis, partially 
offset by higher performance-based compensation expense as a percentage of Net sales.

Other Operating income was $82 million for the year ended December 31, 2018, an increase of $25 million, or 43.9%, 
compared to $57 million for the year ended December 31, 2017. Other Operating income increased primarily due to higher Gross 
profit  dollars,  partially  offset  by  higher  sales  payroll  expenses.  Foreign  exchange  translation  also  had  a  favorable  impact  on 
Operating income. Other operating margin percentage increased 70 basis points to 4.4% for the year ended December 31, 2018, 
from 3.7% for the year ended December 31, 2017. This increase was primarily due to lower sales payroll expenses and lower 
intangible asset amortization as a percentage of Net sales, which does not trend in line with sales movement. 

Net loss on extinguishments of long-term debt

For information regarding our debt, see Note 9 (Long-Term Debt) to the accompanying Consolidated Financial Statements. 

During 2017, we recorded a net loss on extinguishments of long-term debt of $57 million.

We repaid all of the remaining aggregate principal amount outstanding. The loss recognized represents the difference

unamortized deferred financing fees and premium.

Income tax expense

On December 22, 2017, the Tax Cuts and Jobs Act was enacted into law. The Tax Cuts and Jobs Act changed several 
aspects of US federal tax law including: reducing the US corporate income tax rate from 35.0% to 21.0% beginning on January 
1, 2018; applying a one-time tax on the deemed mandatory repatriation of the Company's unremitted foreign earnings which have 
not been subject to US tax; imposing a minimum US tax on foreign earnings; providing for the immediate expensing of certain 
qualified property; and changing the tax treatment of performance-based executive compensation and certain employee fringe 
benefits.

The SEC issued Staff Accounting Bulletin 118 allowing for provisional amounts to be recorded during a measurement 
period not to exceed one year. During the year ended December 31, 2017, the Company recorded provisional amounts for the 
impact of revaluing deferred tax assets and liabilities, the deemed mandatory repatriation tax on the Company's unremitted foreign 
earnings and the state income tax effects from the changes in federal tax law. The Company adjusted the US federal and state 
provisional amounts during 2018, recording a net tax benefit of $2 million. The adjustment was primarily driven by the rate 
differential on adjustments to temporary book-tax differences made in finalizing the 2017 federal income tax return and finalizing 
the deemed mandatory repatriation tax on the Company's unremitted foreign earnings. 

Income tax expense was $198 million in 2018, compared to $138 million in 2017. The effective income tax rate, expressed 
by calculating income tax expense as a percentage of Income before income taxes, was 23.5% and 20.8% for 2018 and 2017, 
respectively.

For 2018, the effective tax rate differed from the US federal statutory rate primarily due to state income taxes, partially 
offset by excess tax benefits on equity compensation. For 2017, the effective tax rate differed from the US federal statutory rate 
primarily due to a one-time benefit of $96 million to reflect the revaluation of deferred tax assets and liabilities, excess tax benefits 
on equity compensation and lower corporate tax rates on our international income, partially offset by state income taxes and a 
one-time charge of $20 million for the mandatory repatriation tax. The 2018 effective tax rate was higher than 2017 primarily due 
to the benefits recorded in 2017 for the Tax Cuts and Jobs Act and excess tax benefits, which exceeded the benefit in 2018 from 
the lower federal income rate in 2018 and partially offset by a higher state income taxes.

Non-GAAP Financial Measure Reconciliations

We have included reconciliations of Non-GAAP income before income taxes, Non-GAAP net income, EBITDA, Adjusted 
EBITDA, Adjusted EBITDA margin and consolidated Net sales growth on a constant currency basis for the years ended December 
31, 2018 and 2017 below. 

Non-GAAP income before income taxes and Non-GAAP net income exclude, among other things, charges related to the 
amortization  of  acquisition-related  intangible  assets,  equity-based  compensation  and  the  associated  tax  benefits,  integration 
expenses, and gains and losses from the extinguishment of long-term debt. EBITDA is defined as consolidated net income before 
interest expense, net, income tax expense, depreciation and amortization. Adjusted EBITDA, which is a measure defined in our 
credit agreements, means EBITDA adjusted for certain items which are described in the table below. Adjusted EBITDA margin 
is defined as Adjusted EBITDA as a percentage of Net sales. Consolidated Net sales growth on a constant currency basis is defined 
as consolidated Net sales growth excluding the impact of foreign currency translation on net sales compared to the prior period.

Non-GAAP  income  before  income  taxes,  Non-GAAP  net  income,  EBITDA, Adjusted  EBITDA, Adjusted  EBITDA 
margin and consolidated Net sales growth on a constant currency basis are considered non-GAAP financial measures. Generally, 
a non-GAAP financial measure is a numerical measure of a company's performance or financial position that either excludes or 
includes amounts that are not normally included or excluded in the most directly comparable measure calculated and presented 
in accordance with GAAP. Non-GAAP measures used by management may differ from similar measures used by other companies, 
even when similar terms are used to identify such measures.

We believe these measures provide analysts, investors and management with helpful information regarding the underlying 
operating performance of our business, as they remove the impact of items that management believes are not reflective of underlying 
operating performance. Management uses these measures to evaluate period-over-period performance as management believes 
they provide a more comparable measure of the underlying business. Additionally, Adjusted EBITDA is a measure in the credit 
agreement governing our Term Loan used to evaluate our ability to make certain investments, incur additional debt, and make 
restricted payments, such as dividends and share repurchases, as well as whether we are required to make additional principal 
prepayments on the Term Loan beyond the quarterly amortization payments. For further details regarding the Term Loan, see Note 
9 (Long-Term Debt) to the accompanying Consolidated Financial Statements.

Amounts for 2017 and 2016 have been adjusted to reflect the adoption of Topic 606.

There were 254 selling days for each of the years ended December 31, 2017 and 2016.

Total Net sales in 2017 increased $1,160 million, or 8.5%, to $14,833 million, compared to $13,673 million for the year 
ended December 31, 2016. Net sales on a constant currency basis, which excludes the impact of currency translation, for the year 
ended December 31, 2017 increased $1,188 million, or 8.7%, to $14,833 million, compared to $13,645 million for the year ended 
December 31, 2016. 

For the year ended December 31, 2017, sales growth was driven by gains in all our customer markets except Healthcare, 
which saw a Net sales decline year over year.  During 2017, and in contrast to 2016, we saw an acceleration of hardware sales, 
driven by strong growth within client device sales due to customer refresh, which impacted categories such as notebooks, mobile 
devices and desktops.  Additionally, we saw growth in several other categories, including video and networking.  We also saw 
ongoing customer focus on designing IT securely, which led to strong sales growth across our entire security portfolio and the 
adoption of more efficient architectures, which drove strong growth in hyper-converged infrastructure and solutions delivered via 
the cloud, as well as the continuing trend of greater integration of software into solutions.  

Corporate  segment  Net  sales  in 2017 increased $438  million,  or 7.6%,  compared  to  2016,  as  customer  confidence 

improved throughout the year. Growth was primarily driven by customer refresh of client devices and networking. 

Small Business segment Net sales in 2017 increased by $102 million, or 9.1%, compared to 2016. Sales growth was 

primarily driven by customer refresh of client devices and video.

Public segment Net sales in 2017 increased $429 million, or 7.8%, compared to 2016. The growth was primarily driven 
by Government and Education customers. Net sales to Federal government customers reflected a focus on spending existing 
budgets on planned projects and ongoing successful alignment with strategic programs, as well as success meeting the Department 
of Defense mandated move to new client devices with stronger security features. Strong Net sales to our State and Local government 
customers was driven by a continued focus on public safety and the on-going success executing against recently added contracts. 
Net sales to our Higher Education customers were driven by networking and software as we continued to see the benefit from 
"connected campus" strategies to ensure network infrastructures can handle multiple devices used by students, faculty and visitors 
across the entire campus. K-12 growth was driven by success in delivering collaborative learning environments and networking. 
Net  sales  to  Healthcare  customers  decreased  3.4%,  reflecting  continued  customer  uncertainty  related  to  reimbursements  and 
funding.

Net sales in Other for 2017 increased $191 million, or 14.2%, compared to 2016. Other is comprised of results from our 
UK and Canadian operations. Both operations had strong growth in local currency as we continued to take share in the local 

38

 
 
 
 
 
 
 
 
Table of Contents

markets, as well as the benefit from increased sales for referrals from US customers to the UK. The impact of foreign currency 
exchange decreased Other sales growth by approximately 250 basis points, due to the impact resulting from the British pound to 
US dollar translation, partially offset by favorable translation of the Canadian to US dollar.

Gross profit

Gross  profit increased $122  million, or 5.2%, to  $2,450 million in 2017, compared to $2,328 million in 2016. As a 
percentage of Net sales, Gross profit decreased 50 basis points to 16.5% in 2017, down from 17.0% in 2016. Although there was 
an increase in Gross profit due to higher sales volumes, we experienced a decline in our Gross profit margin. This decline was 
primarily driven by product margin compression due to increased hardware sales, which generally have lower profit margins, and 
an ongoing competitive marketplace.

Gross profit margin may fluctuate based on various factors, including vendor incentive and inventory price protection 
programs, cooperative advertising funds classified as a reduction of cost of sales, product mix, revenue recognized on a net basis, 
pricing strategies, market conditions and other factors.

Selling and administrative expenses

Selling and administrative expenses increased $65 million, or 4.8%, to $1,410 million in 2017, compared to $1,345 
million in 2016. This was driven by higher sales payroll expenses, including sales commissions, primarily due to higher Gross 
profit, as well as higher coworker costs consistent with increased coworker count. Total coworker count was 8,726 at December 31, 
2017, up 210 from 8,516 at December 31, 2016. Additionally, equity-based compensation expense and the associated payroll taxes 
increased $8 million, or 19.8%, during 2017 compared to 2016, primarily due to the impact of annual equity awards granted under 
our Long-Term Incentive Plan and the vesting of an equity grant made at the time of our initial public offering. Also during 2017, 
a retroactive Illinois state law change was enacted which required the reinstatement of unclaimed property balances, resulting in 
an additional $4 million of expenses. These increases were partially offset by lower senior management incentive compensation.

As a percentage of total Net sales, Selling and administrative expenses decreased 30 basis points to 9.5% in 2017, down 

from 9.8% in 2016.

Operating income was $867 million in 2017, an increase of $47 million, or 5.7%, compared to $820 million in 2016. 
Although Operating income increased, total operating margin percentage decreased 20 basis points to 5.8% in 2017, from 6.0%
in 2016. The decrease was primarily due to Gross profit margin compression from higher hardware sales and an ongoing competitive 
marketplace. Also contributing to lower operating margin percentage was the reinstatement of prior year unclaimed property 
balances in 2017 and the non-recurrence of the settlement payments received from the Dynamic Random Access Memory class 
action lawsuits in 2016. Partially offsetting these decreases were lower sales payroll, consistent with our variable compensation 
cost  structure,  lower  senior  management  incentive  compensation  and  a  decline  in  intangible  asset  amortization  expense  as  a 
percentage of Net sales. 

Corporate segment Operating income was $488 million in 2017, an increase of $34 million, or 7.6%, compared to $454 
million  in  2016.  Corporate  segment  operating  margin  remained  flat  at  7.9%  for  2017  and  2016. Although  Operating  income 
increased, primarily due to an increase in sales volume, Corporate segment operating margin percentage remained flat. The flat 
operating margin percentage reflects higher hardware sales and an ongoing competitive marketplace, which were fully offset by 
lower sales payroll expenses.

Small Business segment Operating income was $74 million in 2017, an increase of $5 million, or 7.4%, compared to $69 
million in 2016. Operating income increased due to an increase in sales volume, while operating margin decreased 10 basis points 
to  6.1%  for  2017.   The  decrease  in  operating  margin  percentage  reflects  higher  hardware  sales  and  an  ongoing  competitive 
marketplace, which were offset by lower sales payroll expenses.

Public segment Operating income was $374 million in 2017, an increase of $6 million, or 1.8%, compared to $368 million 
in 2016. Public segment operating margin decreased 40 basis points to 6.3% in 2017, from 6.7% in 2016. This decrease in operating 
margin percentage was primarily driven by higher hardware sales, which were partially offset by lower sales payroll expenses.

Other Operating income was $57 million in 2017, an increase of $12 million, or 28.2%, compared to $45 million in 2016. 
Other Operating income increased primarily due to higher sales volumes and Gross profit as we continued to take share in the 
local markets. Other operating margin percentage increased 40 basis points to 3.7% in 2017, from 3.3% in 2016. This increase 
was primarily driven by a decline in intangible asset amortization expense as a percentage of Net sales. 

Interest expense, net

Net interest expense in 2017 was $151 million, an increase of $4 million, compared to $147 million in 2016. This increase 
was primarily driven by mark-to-market gains recognized on our interest rate cap agreements in 2016, with no comparable activity 
in 2017 due to the election of hedge accounting in February 2017 and by a rising interest rate environment which resulted in higher 
interest expense on the Term Loan. This was partially offset by a reduced coupon rate due to the refinancing activity that occurred 
during 2017.

We repaid all of the remaining aggregate principal amount outstanding. The loss recognized represents the difference

unamortized deferred financing costs and premium.

Income tax expense

On December 22, 2017, the Tax Cuts and Jobs Act was enacted into law. The Tax Cuts and Jobs Act changed several 
aspects of US federal tax law including: reducing the US corporate income tax rate from 35% to 21% beginning on January 1, 
2018; establishing a territorial tax system, which includes a one-time tax on the deemed mandatory repatriation of our international 
operations' unremitted earnings which have not been subject to US tax; imposing a minimum US tax on foreign earnings; providing 
for  the  immediate  expensing  of  certain  qualified  property;  and  changing  the  tax  treatment  of  performance  based  executive 
compensation and certain employee fringe benefits. GAAP requires the income tax effects of the Tax Cuts and Jobs Act to be 
accounted for in the period of enactment.   

The SEC issued Staff Accounting Bulletin 118 allowing for provisional amounts to be recorded during a measurement 
period not to exceed one year. We recorded provisional amounts for the impact of revaluing deferred tax assets and liabilities, the 
deemed mandatory repatriation tax of our international operations' unremitted earnings and the state income tax effects from the 
change in federal tax law. 

Income tax expense was $138 million in 2017, compared to $248 million in 2016. The effective income tax rate, expressed 
by calculating income tax expense as a percentage of Income before income taxes, was 20.8% and 36.9% for 2017 and 2016, 
respectively.

For 2017, the effective tax rate differed from the US federal statutory rate primarily due to a one-time benefit of $96 
million to reflect the revaluation of deferred tax assets and liabilities under the Tax Cuts and Jobs Act, excess tax benefits on equity 
compensation and lower corporate tax rates on our international income, partially offset by state income taxes and a one-time 
charge of $20 million for the mandatory repatriation tax under the Tax Cuts and Jobs Act. For 2016, the effective tax rate differed 
from the US federal statutory rate primarily due to state income taxes and non-deductible meals and entertainment expenses, which 
were partially offset by lower corporate tax rates on our international income, a deferred tax benefit as a result of a tax rate reduction 
in the UK and excess tax benefits on equity-based compensation as a result of adopting ASU 2016-09, Compensation - Stock 
Compensation. The lower effective tax rate for 2017 as compared to 2016 was primarily attributable to the impact of revaluing 
deferred tax assets and liabilities, and excess tax benefits on equity compensation, offset by a one-time charge for the mandatory 
repatriation tax.

Primarily includes expenses related to payroll taxes on equity-based compensation, our share of net income from our 
equity investment, and historical retention costs during 2017. The year ended December 31, 2016 primarily includes our 
share of the settlement payments received from the Dynamic Random Access Memory class action lawsuits and the 
favorable resolution of a local sales tax matter, partially offset by expenses related to the consolidation of office locations 
north of Chicago. Also comprised of integration expenses related to CDW UK and the reinstatement of prior year unclaimed 
property balances as a result of a retroactive Illinois state law change enacted during 2017.

Consolidated Net sales growth on a constant currency basis

Consolidated Net sales increased $1,160 million, or 8.5%, to $14,833 million for the year ended December 31, 2017, 
compared to $13,673 million for the year ended December 31, 2016. Consolidated Net sales on a constant currency basis, which 
excludes the impact of foreign currency translation, increased $1,188 million, or 8.7%, to $14,833 million for the year ended

Seasonality

While we have not historically experienced significant seasonality throughout the year, sales in our Corporate segment, 
which primarily serves private sector business customers with more than 250 employees, are typically higher in the fourth quarter 
than in other quarters due to customers spending their remaining technology budget dollars at the end of the year. Additionally, 

43

 
 
Table of Contents

sales in our Public segment have historically been higher in the third quarter than in other quarters primarily due to the buying 
patterns of the federal government and education customers.

Liquidity and Capital Resources

Overview

We finance our operations and capital expenditures with internally generated cash from operations. As of December 31, 
2018, we also have $1.1 billion of availability for borrowings under our senior secured asset-based revolving credit facility and 
an additional £50 million ($64 million at December 31, 2018) under the CDW UK revolving credit facility. Our liquidity and 
borrowing plans are established to align with our financial and strategic planning processes and ensure we have the necessary 
funding to meet our operating commitments, which primarily include the purchase of inventory, payroll and general expenses. We 
also take into consideration our overall capital allocation strategy, which includes investment for future growth, dividend payments, 
acquisitions and stock repurchases. We believe we have adequate sources of liquidity and funding available for at least the next 
year; however, there are a number of factors that may negatively impact our available sources of funds. The amount of cash 
generated  from  operations  will  be  dependent  upon  factors  such  as  the  successful  execution of  our  business  plan  and  general 
economic conditions.

Long-Term Debt and Financing Arrangements

As of December 31, 2018, we had total indebtedness of $3.2 billion, of which $1.5 billion was secured indebtedness. At 
December 31, 2018, we were in compliance with the covenants under our various credit agreements and indentures. The amount 
of CDW's restricted payment capacity under the Senior Secured Term Loan Facility was $1.5 billion at December 31, 2018. The 
amount of restricted payment capacity for the CDW UK term loan was $163 million.

For additional details regarding our debt and refinancing activities, refer to Note 9 (Long-Term Debt) to the accompanying 

Consolidated Financial Statements.

Inventory Financing Agreements

We have entered into agreements with certain financial intermediaries to facilitate the purchase of inventory from various 
suppliers under certain terms and conditions. These amounts are classified separately as Accounts payable-inventory financing 
on the Consolidated Balance Sheets. We do not incur any interest expense associated with these agreements as balances are paid 
when they are due. For further details, see Note 5 (Inventory Financing Agreements) to the accompanying Consolidated Financial 
Statements.

Share Repurchase Program

During 2018, we repurchased 6.3 million shares of our common stock for $522 million under the previously announced 
share repurchase program. On February 7, 2019, we announced that our Board of Directors authorized a $1.0 billion increase to 
our share repurchase program. For more information on our share repurchase program, see Item 5, "Market for Registrant's Common 
Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities."

Amounts for 2017 have been adjusted to reflect the adoption of Topic 606.

Includes items such as deferred income taxes, depreciation and amortization, equity-based compensation expense and 
Net loss on extinguishments of long-term debt.

The change is primarily due to stronger operating results driven by Net sales and Gross profit growth, partially offset by 
higher sales payroll.

The change in Accounts receivable is primarily due to increased sales volume in 2018 compared to 2017 and longer 
payment cycles for certain Public segment customers.

The change in Merchandise inventory is primarily due to growth in business and timing of shipments to customers in 
2018, as well as lower inventory levels at the end of 2017.

The change in Accounts payable-trade is due to increased sales in 2018 and the timing of inventory purchases.

The change in Other is driven by improved collection performance of our receivables from vendors, higher accrued 
compensation expense in 2018 and the settlement of our Restricted Debt Unit Plan liability in 2017.

Amounts for 2017 and 2016 have been adjusted to reflect the adoption of Topic 606.

Includes items such as deferred income taxes, depreciation and amortization, equity-based compensation expense and 
Net loss on extinguishments of long-term debt.

The change is primarily due to stronger operating results driven by Net sales and Gross profit growth and excess tax 
benefits recognized related to equity-based compensation.

The change in Accounts receivable was primarily due to the timing of sales compared to the same period in 2016.

The change in Merchandise inventory was primarily due to higher inventory levels in 2016 as a result of the timing of 
inventory shipments to customers, increased returns and higher bill-and-hold orders.

The change in Other is driven by an increase in the receivables from vendors due to the growth in business and the 
settlement of our Restricted Debt Unit Plan liability, partially offset by an increase in accrued marketing expenses.

In order to manage our working capital and operating cash needs, we monitor our cash conversion cycle, defined as days 
of sales outstanding in accounts receivable plus days of supply in inventory minus days of purchases outstanding in accounts 
payable, based on a rolling three-month average. Components of our cash conversion cycle are as follows:

(in days)
Days of sales outstanding (DSO)(2)
Days of supply in inventory (DIO)(3)
Days of purchases outstanding (DPO)(4)

The cash conversion cycle was 19 days at December 31, 2018 and 2017. The increase in DSO was primarily driven by 
higher Net sales and related Accounts receivable recognized on a net basis such as SaaS, software assurance and warranties and 
longer payment cycles for certain Public segment customers. The third-party services have an unfavorable impact on DSO as the 
receivable  is  recognized  on  the  Consolidated  Balance  Sheet  on  a  gross  basis  while  the  corresponding  sales  amount  in  the 
Consolidated Statement of Operations is recorded on a net basis. This also results in a favorable impact on DPO as the payable is 

46

Table of Contents

recognized on the Consolidated Balance Sheet without a corresponding Cost of sales in the Statement of Operations because the 
cost paid to the vendor or third-party service provider is recorded as a reduction to Net sales. DPO was also impacted by the timing 
of inventory purchases.

Investing Activities

Net cash used in investing activities increased $5 million in 2018 compared to 2017. The increase in cash used primarily 

related to improvements to our information technology systems.

Net cash used in investing activities increased $15 million in 2017 compared to 2016. The increase in cash used was 

primarily related to improvements to our information technology systems.

Financing Activities

Net cash used in financing activities decreased $64 million in 2018 compared to 2017. The decrease was primarily driven 
by 2017 payments to extinguish long-term debt which did not repeat in 2018, an increase in stock options exercised and lower 
incentive compensation plan withholding taxes, partially offset by an increase in dividends paid. 

Net cash used in financing activities increased $514 million in 2017 compared to 2016. The increase was primarily driven 
by changes in accounts payable-inventory financing, which resulted in an increase in cash used in financing activities of $228 
million and by share repurchases during 2017, which resulted in an increase in cash used in financing activities of $167 million. 
The increase in cash used for Accounts payable-inventory financing was primarily driven by the termination of one of our inventory 
financing agreements in the fourth quarter of 2016, with amounts owed subsequently reported as Accounts payable - trade on the 
Consolidated Balance Sheet, which reduced cash flows reported as financing activities during 2017. In addition, an increase in 
incentive compensation plan tax withholdings paid of $50 million, coupled with an increase in dividends paid of $28 million, 
contributed to the increase in cash used in financing activities.

Contractual Obligations

We have future obligations under various contracts relating to debt and interest payments, operating leases and asset 
retirement obligations. Our estimated future payments, based on undiscounted amounts, under contractual obligations that existed 
as of December 31, 2018, are as follows:

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect 
on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures 
or capital resources.

Inflation

Inflation has not had a material impact on our operating results. We generally have been able to pass along price increases 
to our customers, though certain economic factors and technological advances in recent years have tended to place downward 
pressure on pricing. We also have been able to generally offset the effects of inflation on operating costs by continuing to emphasize 
productivity improvements. There can be no assurances, however, that inflation would not have a material impact on our sales or 
operating costs in the future. 

Commitments and Contingencies

The information set forth in Note 15 (Commitments and Contingencies) to the accompanying Consolidated Financial 

Statements included in Part II, Item 8 of this Form 10-K is incorporated herein by reference. 

Critical Accounting Policies and Estimates

The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make use 
of certain estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as related 
disclosure of contingent assets and liabilities in the Consolidated Financial Statements and accompanying notes. We base our 
estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. 
Historically, we have not made significant changes to the methods for determining these estimates as our actual results have not 
differed materially from our estimates. We do not believe it is reasonably likely that the estimates and related assumptions will 
change materially in the foreseeable future; however, actual results could differ from those estimates under different assumptions, 
judgments or conditions. We have reviewed our critical accounting policies with the Audit Committee of our Board of Directors.

Critical accounting policies and estimates are those that are most important to the portrayal of our financial condition 
and results of operations, and which require us to make our most difficult and subjective judgments, often as a result of the need 
to make estimates of matters that are inherently uncertain. Based on this definition, we have identified the critical accounting 
policies and estimates addressed below. For more information related to significant accounting policies used in the preparation of 
our Consolidated Financial Statements, see Note 1 (Description of Business and Summary of Significant Accounting Policies) to 
the accompanying Consolidated Financial Statements.

Revenue Recognition

We sell some of our products and services as part of bundled contract arrangements containing multiple deliverables, 
which may include a combination of different products and services. Significant judgment may be required when determining 
whether products and services are considered distinct performance obligations that should be accounted for separately versus 
together. 

For each deliverable that represents a distinct performance obligation, total arrangement consideration is allocated based 
upon the standalone selling prices of each performance obligation. Judgment is required to determine the standalone selling price 
for each distinct performance obligation. For certain performance obligations, we will use a combination of methods to estimate 
the standalone selling price based on recent transactions. When evidence from recent transactions is not available to confirm that 
the prices are representative of the standalone selling price, an expected cost plus a margin approach is used.

Additional judgment is required in determining whether we are the principal, and report revenues on a gross basis, or 
agent, and report revenues on a net basis. We evaluate the following indicators amongst others when determining whether we are 

48

 
 
 
 
 
Table of Contents

acting as a principal in the transaction and recording revenue on a gross basis: (i) we are primarily responsible for fulfilling the 
promise  to  provide  the  specified  goods  or  service,  (ii)  we  have  inventory  risk  before  the  specified  good  or  service  has  been 
transferred to a customer or after transfer of control to the customer and (iii) we have discretion in establishing the price for the 
specified good or service. If the terms of a transaction do not indicate we are acting as a principal in the transaction, then we are 
acting as an agent in the transaction and the associated revenues are recognized on a net basis. 

The nature of our contracts give rise to variable consideration in the form of sales returns and allowances. We estimate 
variable consideration at the most likely amount to which we are expected to be entitled. The estimates of variable consideration 
and determination of whether to include estimated amounts in the transaction price are based on an assessment of our anticipated 
performance and all information that is reasonably available. 

We generally recognize revenue on the sale of hardware and software products upon delivery to the customer. As a result, 
we perform an analysis to estimate the amount of Net sales in-transit at the end of the period and adjust revenue and the related 
costs to reflect only what has been delivered to the customer.  This analysis requires judgment whereby we perform an analysis 
of the estimated number of days of sales in-transit to customers at the end of each reporting period based on a weighted-average 
analysis of commercial delivery terms that include drop-shipment arrangements. Changes in delivery patterns may result in a 
different number of business days estimated to make this adjustment.

Vendor Programs

We  receive  incentives  from  certain  vendors  related  to  cooperative  advertising,  volume  rebates,  bid  programs,  price 
protection and other programs. These incentives generally relate to written agreements with specified performance requirements 
with the vendors and are recorded as adjustments to Cost of sales or Merchandise inventory, depending on the nature of the 
incentive. We record vendor partner receivables related to these programs when the amounts are probable and reasonably estimable. 
Some programs are based on the achievement of specific targets, and we base our estimates on information provided by our vendors 
and internal information to assess our progress toward achieving those targets. 

We also record reserves for vendor partner receivables for estimated losses due to vendors' inability to pay or rejections 
by vendors of claims. In estimating the required allowance, we take into consideration collections performance and the aging of 
the incentive receivables, as well as specific vendor circumstances.

Goodwill 

Goodwill is allocated to reporting units expected to benefit from the business combination. Goodwill is not amortized 
but is subject to periodic testing for impairment at the reporting unit level on an annual basis each December 1, or more frequently 
if events or changes in circumstances indicate that the asset may be impaired. These events or circumstances could include a 
significant change in the business climate, legal factors, operating performance indicators, competition or sale or disposition of a 
significant portion of a reporting unit. 

We may elect to utilize a qualitative assessment to determine whether it is more likely than not that the fair value of a 
reporting unit is less than its carrying value. As part of our qualitative assessment, judgment is required in weighing the effect of 
various positive and negative factors that may affect the fair value. We consider various factors, including the excess of fair value 
over carrying value from the last quantitative test, macroeconomic conditions, industry and market considerations, the projected 
financial performance and actual financial performance compared to prior year projected financial performance, as well as other 
factors.

If we elect to bypass the qualitative assessment, or if indicators of impairment exist, a quantitative impairment test is 
performed. As part of the quantitative assessment, application of the goodwill impairment test requires judgment, including the 
identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, 
and  determination  of  the  fair  value  of  each  reporting  unit.  Fair  value  of  a  reporting  unit  is  determined  by  using  a  weighted 
combination of an income approach and a market approach, as this combination is considered the most indicative of our fair value 
in an orderly transaction between market participants. This analysis requires significant judgments, including estimation of future 
cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of 
the useful life over which cash flows will occur, determination of our weighted average cost of capital, future market conditions 
and profitability of future business strategies. The estimates used to calculate the fair value of a reporting unit change from year 
to year based on operating results, market conditions and other factors. Changes in these estimates and assumptions could materially 
affect the determination of fair value and goodwill impairment for each reporting unit. However, our past estimates of fair value 
would not have been materially different when revised to include subsequent years' actual results.

Table of Contents

Intangible Assets

Intangible  assets  include  customer  relationships,  trade  names,  internally  developed  software  and  other  intangibles. 
Intangible assets are amortized on a straight-line basis over the estimated useful life of the asset and reviewed for impairment 
when events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The valuation 
and classification of these assets and the assignment of useful lives involve significant judgment and the use of estimates. The 
valuation, classification and assignment of useful lives were derived using market inputs, historic experience and third-party 
guidance. 

Income Taxes

The determination of our provision for income taxes and evaluating our tax positions requires significant judgment, the 
use of estimates and the interpretation and application of complex tax laws. Our provision for income taxes primarily reflects a 
combination of income earned and taxed in the various U.S. federal and state, as well as foreign, jurisdictions. Our annual effective 
tax rate is based on our income, the jurisdiction(s) in which the income is earned and subjected to taxation, the tax laws in those 
various jurisdictions which can be affected by tax law changes, increases or decreases in permanent differences between book and 
tax items, and accruals or adjustments of accruals for unrecognized tax benefits or valuation allowances. 

We establish reserves to remove some or all of the tax benefit of any of our tax positions at the time we determine that 
the position becomes uncertain based upon one of the following: (1) the tax position is not "more likely than not" to be sustained, 
(2) the tax position is "more likely than not" to be sustained, but for a lesser amount, or (3) the tax position is "more likely than 
not" to be sustained, but not in the financial period in which the tax position was originally taken. Reserves related to tax accruals 
and valuations allowances related to deferred tax assets can be impacted by changes in tax law in the relevant jurisdiction(s) and 
our future taxable income levels in the relevant jurisdiction(s) with respect to valuation allowances.

Item 7A. Quantitative and Qualitative Disclosures of Market Risks

Interest Rate Risk

Our market risks relate primarily to changes in interest rates. The interest rates on borrowings under our senior secured 
asset-based revolving credit facility, our senior secured term loan facility and the CDW UK term loan are floating and, therefore, 
are subject to fluctuations. In order to manage the risk associated with changes in interest rates on borrowings under our senior 
secured term loan facility, we have entered into interest rate caps to add stability to interest expense and to manage our exposure 
to interest rate fluctuations.

As of December 31, 2018, we have interest rate cap agreements in effect with a combined notional amount of $1.4 billion. 

For additional details, see Note 8 (Financial Instruments) to the accompanying Consolidated Financial Statements. 

See "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital 

Resources - Contractual Obligations" for information on cash flows, interest rates and maturity dates of our debt obligations.

Foreign Currency Risk

We transact business in foreign currencies other than the US dollar, primarily the British pound and the Canadian dollar, 
which exposes us to foreign currency exchange rate fluctuations. Revenue and expenses generated from our international operations 
are generally denominated in the local currencies of the corresponding countries. The functional currency of our international 
operating subsidiaries is the same as the corresponding local currency. Upon consolidation, as results of operations are translated, 
operating results may differ from expectations. The direct effect of foreign currency fluctuations on our results of operations has 
not been material as the majority of our results of operations are denominated in US dollars.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of CDW Corporation and subsidiaries

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  CDW  Corporation  and  subsidiaries  (the  Company)  as  of 
December 31, 2018, and 2017, the related statements of consolidated statements of operations, comprehensive income, stockholders' 
equity, and cash flows for each of the three years in the period ended December 31, 2018, and the related notes and financial 
statement schedule listed in the Index at Item 15(a) (2) (collectively referred to as the "consolidated financial statements"). In our 
opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of 
December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2018, in conformity with US generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in 
Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 
framework), and our report dated February 27, 2019 expressed an unqualified opinion thereon. 

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on 
the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are 
required to be independent with respect to the Company in accordance with the US 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 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error 
or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether 
due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, 
evidence regarding the amounts and disclosures in the 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 financial 
statements. We believe that our audits provide a reasonable basis for our opinion. 

/s/ Ernst & Young LLP

We have served as the Company's auditor since 2011.

Description of Business and Summary of Significant Accounting Policies

Description of Business

CDW  Corporation  ("Parent")  is  a  Fortune  500  company  with  multi-national  capabilities  and  a  leading  provider  of 
integrated information technology ("IT") solutions to small, medium and large business, government, education and 
healthcare customers in the United States ("US"), the United Kingdom ("UK") and Canada. The Company's offerings 
range from discrete hardware and software products to integrated IT solutions such as mobility, security, data center 
optimization, cloud computing, virtualization and collaboration.

Throughout this report, the terms "the Company" and "CDW" refer to Parent and its 100% owned subsidiaries.

Parent has two 100% owned subsidiaries, CDW LLC and CDW Finance Corporation. CDW LLC is an Illinois limited 
liability company that, together with its 100% owned subsidiaries, holds all material assets and conducts all business 
activities and operations of the Company. CDW Finance Corporation is a Delaware corporation formed for the sole 
purpose of acting as co-issuer of certain debt obligations as described in Note 17 (Supplemental Guarantor Information)
and does not hold any material assets or engage in any business activities or operations.

Basis of Presentation

The Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted 
in the United States of America ("GAAP") and the rules and regulations of the US Securities and Exchange Commission 
("SEC").

Effective  January  1,  2018,  the  Company  adopted  the  requirements  of ASU  2014-09,  Revenue  from  Contracts  with 
Customers, as amended ("Topic 606") utilizing the full retrospective method. Prior period amounts have been adjusted 
accordingly.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of Parent and its 100% owned subsidiaries. All intercompany 
transactions and accounts are eliminated in consolidation. 

Use of Estimates

The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make use 
of certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent 
assets and liabilities as of the date of the Consolidated Financial Statements and the reported amounts of revenue and 
expenses during the reported periods. The Company bases its estimates on historical experience and on various other 
assumptions that management believes are reasonable under the circumstances, the results of which form the basis for 
making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual 
results could differ from those estimates.

Business Combinations

The Company accounts for all business combinations using the acquisition method of accounting, which allocates the 
fair value of the purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on 
their estimated fair values. The excess of the purchase consideration over the fair values of these identifiable assets and 
liabilities is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management 
makes significant estimates and assumptions. The Company may utilize third-party valuation specialists to assist the 
Company in the allocation. Initial purchase price allocations are subject to revision within the measurement period, not 
to exceed one year from the date of acquisition. Acquisition-related expenses and transaction costs associated with business 
combinations are expensed as incurred.

Cash and Cash Equivalents

Cash and cash equivalents include all deposits in banks and short-term (original maturities of three months or less at the 
time of purchase), highly liquid investments that are readily convertible to known amounts of cash and are so near maturity 
that there is insignificant risk of changes in value due to interest rate changes.

Accounts Receivable

CDW CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Trade accounts receivable are recorded at the invoiced amount and typically do not bear interest. The Company provides 
allowances for doubtful accounts related to accounts receivable for estimated losses resulting from the inability of its 
customers to make required payments. The Company takes into consideration the overall quality of the receivable portfolio 
along with specifically-identified customer risks in establishing the allowance.

Merchandise Inventory

Inventory is valued at the lower of cost and net realizable value. Cost is determined using a weighted-average cost method. 
Price protection is recorded when earned as a reduction to the cost of inventory. The Company decreases the value of 
inventory for estimated obsolescence equal to the difference between the cost of inventory and the net realizable value, 
based upon an aging analysis of the inventory on hand, specifically known inventory-related risks and assumptions about 
future demand and market conditions.

Miscellaneous Receivables

Miscellaneous receivables primarily consist of amounts due from vendors. The Company receives incentives from vendors 
related to cooperative advertising, volume rebates, bid programs, price protection and other programs. These incentives 
generally relate to written vendor agreements with specified performance requirements and are recorded as adjustments 
to Cost of sales or Merchandise inventory, depending on the nature of the incentive.

Property and Equipment 

Property and equipment are stated at cost, less accumulated depreciation. The Company calculates depreciation expense 
using the straight-line method over the estimated useful lives of the assets. Property and equipment are reviewed annually 
to determine whether there is any impairment. Determination of recoverability is based on an estimate of undiscounted 
future cash flows resulting from the use of the asset and its eventual disposition. If the carrying amount of an asset exceeds 
its estimated future undiscounted cash flows, an impairment loss is recorded for the excess of the asset's carrying amount 
over its fair value. Leasehold improvements are amortized over the shorter of their estimated useful lives or the remaining 
lease term. Expenditures for major renewals and improvements that extend the useful life of property and equipment are 
capitalized. Expenditures for maintenance and repairs are charged to expense as incurred. The estimated useful lives of 
property and equipment are as follows:

Classification
Machinery and equipment

Building and leasehold improvements

Computer and data processing equipment

Computer software

Furniture and fixtures

Goodwill

Estimated

5 to 10 years

5 to 25 years

The  Company  performs  an  evaluation  of  goodwill,  utilizing  either  a  qualitative  or  quantitative  impairment  test. A 
qualitative assessment is performed at least on an annual basis to determine whether it is more likely than not that the 
fair value of a reporting unit is less than its carrying value. The Company performs a quantitative impairment test for 
each reporting unit every three years, or more frequently if circumstances indicate a potential impairment. The annual 
test for impairment is conducted as of December 1. The Company's reporting units included in the assessment of potential 
goodwill impairment are the same as its operating segments. Goodwill is not amortized but is subject to periodic testing 
for impairment at the reporting unit level. 

Under a qualitative assessment, the most recent quantitative assessment is used to determine if it is more- likely-than-
not that the reporting unit's goodwill is impaired. As part of this qualitative assessment, the Company assesses relevant 
events and circumstances including macroeconomic conditions, industry and market conditions, cost factors, overall 
financial performance, changes in share price and entity-specific events to determine if there is an indication of impairment.

Under a quantitative assessment, goodwill impairment is identified by comparing the fair value of a reporting unit to its 
carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, goodwill is considered 
impaired and an impairment charge is recognized in an amount equal to that excess, not to exceed the carrying amount

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

of goodwill. Fair value of a reporting unit is determined by using a weighted combination of an income approach (75%) 
and a market approach (25%), as this combination is considered the most indicative of the Company's fair value in an 
orderly transaction between market participants. 

Under the income approach, the Company determines fair value based on estimated future cash flows of a reporting unit, 
discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk of a reporting 
unit and the rate of return an outside investor would expect to earn. The estimated future cash flows of each reporting 
unit are based on internally generated forecasts for the remainder of the respective reporting period and the next five 
years.

Under the market approach, the Company utilizes valuation multiples derived from publicly available information for 
guideline companies to provide an indication of how much a knowledgeable investor in the marketplace would be willing 
to pay for a company. The valuation multiples are applied to the reporting units. 

Determining the fair value of a reporting unit is judgmental in nature and requires the use of significant estimates and 
assumptions, including Net sales growth rates, gross profit margins, operating margins, discount rates and future market 
conditions, among others. Any changes in the judgments, estimates or assumptions used could produce significantly 
different results. 

Intangible Assets

Intangible assets with determinable lives are amortized on a straight-line basis over their respective estimated useful 
lives. The cost of computer software developed or obtained for internal use is capitalized and amortized on a straight-
line basis over the estimated useful life of the software. Intangible assets are reviewed for impairment when events or 
changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of 
recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual 
disposition. If the carrying amount of an asset exceeds its estimated future undiscounted cash flows, an impairment loss 
is  recorded  for  the  excess of  the asset's  carrying amount  over  its  fair value.  In  addition, each  quarter,  the Company 
evaluates whether events and circumstances warrant a revision to the remaining estimated useful life of each of these 
intangible assets. If the Company were to determine that a change to the remaining estimated useful life of an intangible 
asset was necessary, then the remaining carrying amount of the intangible asset would be amortized prospectively over 
that revised remaining useful life.

The following table shows estimated useful lives of definite-lived intangible assets:

Classification

Deferred Financing Costs

Useful Lives

3 to 14 years

generally 20 years

Deferred financing costs, such as underwriting, financial advisory, professional fees and other similar fees are capitalized 
and recognized in Interest expense, net over the estimated life of the related debt instrument using the effective interest 
method or straight-line method, as applicable. The Company classifies deferred financing costs as a direct deduction 
from the carrying value of the Long-term debt liability on the Consolidated Balance Sheets, except for deferred financing 
costs associated with revolving credit facilities which are presented as an asset, within Other assets on the Consolidated 
Balance Sheets. 

Derivative Instruments

The Company has interest rate cap agreements for the purpose of hedging its exposure to fluctuations in interest rates.  
The interest rate cap agreements are designated as cash flow hedges of interest rate risk and recorded at fair value in 
Other assets on the Consolidated Balance Sheets. Changes in fair value of the derivative instruments, along with the 
change in the fair value of the hedged item, are reported as a component of Accumulated other comprehensive loss until 
reclassified to Interest expense in the same period the hedge transaction affects earnings.

Fair Value Measurements

Fair value is defined under GAAP 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. A fair value hierarchy has been established for 
valuation inputs to prioritize the inputs into three levels based on the extent to which inputs used in measuring fair value 
are observable in the market. Each fair value measurement is reported in one of the three levels which is determined by 
the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

Level 1 – observable inputs such as quoted prices for identical instruments traded in active markets.

Level 2 – inputs are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar 
instruments in markets that are not active and model-based valuation techniques for which all significant assumptions 
are observable in the market or can be corroborated by observable market data for substantially the full term of the assets 
or liabilities.

Level 3 – inputs are generally unobservable and typically reflect management's estimates of assumptions that market 
participants  would  use  in  pricing  the  asset  or  liability.  The  fair  values  are  therefore  determined  using  model-based 
techniques that include option pricing models, discounted cash flow models and similar techniques.

Revenue Recognition

The Company is a primary distribution channel for a large group of vendors and suppliers, including original equipment 
manufacturers ("OEMs"), software publishers and wholesale distributors.

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties 
are identified, payment terms are established, the contract has commercial substance and collectability of consideration 
is probable. The Company evaluates the following indicators amongst others when determining whether it is acting as a 
principal in the transaction and recording revenue on a gross basis: (i) the Company is primarily responsible for fulfilling 
the promise to provide the specified goods or service, (ii) the Company has inventory risk before the specified good or 
service has been transferred to a customer or after transfer of control to the customer and (iii) the Company has discretion 
in establishing the price for the specified good or service. If the terms of a transaction do not indicate the Company is 
acting as a principal in the transaction, then the Company is acting as an agent in the transaction and the associated 
revenues are recognized on a net basis.

The Company recognizes revenue once control has passed to the customer. The following indicators are evaluated in 
determining when control has passed to the customer: (i) the Company has a right to payment for the product or service, 
(ii) the customer has legal title to the product, (iii) the Company has transferred physical possession of the product to the 
customer, (iv) the customer has the significant risk and rewards of ownership of the product and (v) the customer has 
accepted the product. The Company's products can be delivered to customers in a variety of ways, including (i) as physical 
product shipped from the Company's warehouse, (ii) via drop-shipment by the vendor or supplier or (iii) via electronic 
delivery of keys for software licenses. The Company's shipping terms typically allow for the Company to recognize 
revenue when the product reaches the customer's location.

The Company leverages drop-shipment arrangements with many of its vendors and suppliers to deliver products to its 
customers  without  having  to  physically  hold  the  inventory  at  its  warehouses.  The  Company  is  the  principal  in  the 
transaction and recognizes revenue for drop-shipment arrangements on a gross basis.

Revenue Recognition for Hardware

Revenues from sales of hardware products are recognized on a gross basis as the Company is acting as a principal in 
these transactions, with the selling price to the customer recorded as Net sales and the acquisition cost of the product 
recorded as Cost of sales. The Company recognizes revenue from these transactions when control has passed to the 
customer, which is usually upon delivery of the product to the customer. 

In some instances, the customer agrees to buy the product from the Company but requests delivery at a later date, commonly 
known as bill-and-hold arrangements. For these transactions, the Company deems that control passes to the customer 
when the product is ready for delivery. The Company views products ready for delivery when the customer has a signed 
agreement, significant risk and rewards for the products, the ability to direct the assets, the products have been set aside 
specifically for the customer, cannot be redirected to another customer and for customer orders that include configuration 
services, when such services have been completed.

CDW CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company's vendor partners warrant most of the products the Company sells. These manufacturer warranties are 
assurance-type warranties and are not considered separate performance obligations. The warranties are not sold separately 
and only provide assurance that products will conform with the manufacturer's specifications. In some transactions, a 
third-party will provide the customer with an extended warranty. These extended warranties are sold separately and 
provide the customer with a service in addition to assurance that the product will function as expected. The Company 
considers  these  warranties  to  be  separate  performance  obligations  from  the  underlying  product.  For  warranties,  the 
Company is arranging for those services to be provided by the third-party and therefore is acting as an agent in the 
transaction and records revenue on a net basis at the point of sale.

The Company sells cloud computing solutions which include Infrastructure as a Service ("IaaS"). IaaS solutions utilize 
third-party partners to enable customers to access data center functionality in a cloud-based solution, including storage, 
computing and networking. The Company recognizes revenue for cloud computing solutions for arrangements with one-
time invoicing to the customer at the time of invoice on a net basis as the Company is acting as an agent in the transaction. 
For monthly subscription-based arrangements, the Company is acting as an agent in the transaction and recognizes revenue 
as it invoices the customer for its monthly usage on a net basis.

Revenue Recognition for Software

Revenues from most software license sales are recognized as a single performance obligation on a gross basis as the 
Company is acting as a principal in these transactions at the point the software license is delivered to the customer. 
Generally, software licenses are sold with accompanying third-party delivered software assurance, which is a product 
that allows customers to upgrade, at no additional cost, to the latest technology if new capabilities are introduced during 
the period that the software assurance is in effect. The Company evaluates whether the software assurance is a separate 
performance obligation by assessing if the third-party delivered software assurance is critical or essential to the core 
functionality of the software itself. This involves considering if the software provides its original intended functionality 
to the customer without the updates, if the customer would ascribe a higher value to the upgrades versus the up-front 
deliverable, if the customer would expect frequent intelligence updates to the software (such as updates that maintain the 
original functionality), and if the customer chooses to not delay or always install upgrades. If the Company determines 
that the accompanying third-party delivered software assurance is critical or essential to the core functionality of the 
software license, the software license and the accompanying third-party delivered software assurance are recognized as 
a single performance obligation. The value of the product is primarily the accompanying support delivered by a third-
party and therefore the Company is acting as an agent in these transactions and recognizes them on a net basis at the point 
the associated software license is delivered to the customer. For software licenses where the accompanying third-party 
delivered software assurance is not critical or essential to the core functionality, the software assurance is recognized as 
a separate performance obligation, with the associated revenue recognized on a net basis at the point the related software 
license  is  delivered  to  the  customer.  For  additional  details  regarding  the  accounting  for  bundled  arrangements,  see 
"Revenue Recognition for Bundled Arrangements" below.

The Company sells cloud computing solutions which include Software as a Service ("SaaS"). SaaS solutions utilize third-
party partners to offer the Company's customers access to software in the cloud that enhances office productivity, provides 
security or assists in collaboration. The Company recognizes revenue for cloud computing solutions for arrangements 
with one-time invoicing to the customer at the time of invoice on a net basis as the Company is acting as an agent in the 
transaction. For monthly subscription-based arrangements, the Company is acting as an agent in the transaction and 
recognizes revenue as it invoices the customer for its monthly usage on a net basis.

The Company's customers are offered the opportunity by certain of its vendors to purchase software licenses and software 
assurance under enterprise agreements ("EAs"). For most EA transactions, the Company's obligation to the customer is 
that of a distributor or sales agent of the services, where all obligations for providing the services to customers are passed 
to the Company's vendors. The Company's performance obligations are satisfied at the time of the sale. In other EA 
transactions, the Company is responsible for fulfilling the promised services to the customer and providing remedy or 
refund for work if the customer is not satisfied with the delivered services, has inventory risk in the arrangement and has 
full control to set the price for the customer. With most EAs, the Company's vendors will transfer the license and invoice 
the customer directly, paying resellers an agency fee or commission on these sales. The Company records these fees as 
a component of Net sales as earned and there is no corresponding Cost of sales amount.

Revenue Recognition for Services

The Company provides professional services, which include project managers and consultants recommending, designing 
and implementing IT solutions. Revenue from professional services is recognized either on a time and materials basis or 

63

Table of Contents

CDW CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

proportionally as costs are incurred for fixed fee project work. Revenue is recognized on a gross basis each month as 
work is performed and the Company transfers those services. 

Revenues from the sale of data center services, such as managed and remote managed services, server co-location, internet 
connectivity and data backup and storage provided by the Company, are recognized over the period the service is provided. 
Most  hosting  and  managed  service  obligations  are  based  on  the  quantity  and  pricing  parameters  established  in  the 
agreement. As the customer receives the benefit of the service each month, the Company recognizes the respective revenue 
on a gross basis as the Company is acting as a principal in the transaction. Additionally, the Company's managed services 
team provides project support to customers that are billed on a fixed fee basis. The Company is acting as the principal 
in the transaction and recognizes revenue on a gross basis based on the total number of hours incurred for the period over 
the total expected hours for the project. Total expected hours to complete the project is updated for each period and best 
represents the transfer of control of the service to the customer.

Revenue Recognition for Bundled Arrangements

The Company also sells some of its products and services as part of bundled contract arrangements containing multiple 
deliverables, which may include a combination of products and services. For each deliverable that represents a distinct 
performance obligation, total arrangement consideration is allocated based upon the standalone selling prices of each 
performance obligation. The Company excludes amounts collected on behalf of third-parties, such as sales taxes, when 
determining the transaction price. For certain performance obligations, the Company will use a combination of methods 
to estimate the standalone selling price. When evidence from recent transactions is not available to confirm that the prices 
are representative of the standalone selling price, an expected cost plus a margin approach is used.

Sales In-Transit

The Company performs an analysis of the estimated number of days of sales in-transit to customers at the end of each 
reporting  period  based  on  a  weighted-average  analysis  of  commercial  delivery  terms  that  include  drop-shipment 
arrangements. This analysis is the basis upon which the Company estimates the amount of Net sales in-transit at the end 
of the period and adjusts revenue and the related costs to reflect only what has been delivered to the customer. Changes 
in delivery patterns may result in a different number of business days estimated to make this adjustment.

Freight Costs

The Company records freight billed to its customers as Net sales and the related freight costs as Cost of sales when the 
underlying product revenue is recognized. For freight not billed to its customers, the Company records the freight costs 
as Cost of sales. The Company's typical shipping terms result in shipping being performed before the customer obtains 
control of the product. The Company considers shipping to be a fulfillment activity and not a separate performance 
obligation.

Other

The nature of the Company's contracts give rise to variable consideration in the form of sales returns and allowances. 
The Company estimates variable consideration at the most likely amount to which it is expected to be entitled. This 
estimated amount is included in the transaction price to the extent it is probable that a significant reversal of cumulative 
revenue  recognized  will  not  occur  when  the  uncertainty  associated  with  the  variable  consideration  is  resolved. The 
estimates of variable consideration and determination of whether to include estimated amounts in the transaction price 
are based on an assessment of the Company's anticipated performance and all information that is reasonably available. 
At the time of sale, the Company records an estimate for sales returns and allowances and an associated right of return 
asset based on historical experience.

When a contract results in revenue being recognized in excess of the amount the Company has the right to invoice to the 
customer, a contract asset is recorded on the balance sheet. Contract assets are comprised primarily of professional services 
with fixed fee arrangements.

Contract  liabilities  consist  of  payments  received  from  customers,  or  such  consideration  that  is  contractually  due,  in 
advance of providing the product or performing services. Contract liabilities are comprised primarily of professional 
services with fixed fee arrangements, bill-and-hold transactions where control has not passed to the customer and certain 
governmental contracts.

CDW CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Trade accounts receivable are recorded at the point of sale (or in accordance with the Statement of Work for services) 
for the total amount payable by the customer to the Company for sale of goods. Taxes to be collected from the customer 
as part of the sale are included in Accounts receivable.

Any incremental direct costs of obtaining a contract, primarily sales commissions, are deferred on the Consolidated 
Balance Sheets and amortized over the period of contract performance.

The Company typically does not enter into long-term contracts. The Company has elected to use the practical expedient 
for its performance obligations table to show only those contracts that are longer than 12 months at the time of contract 
inception and those contracts that are non-cancelable. Additionally, for certain governmental contracts where there are 
annual renewals, the Company has excluded these contracts since there is only a one-year legal obligation. Typically, the 
only contracts that are longer than 12 months in duration are related to the Company's managed services business.

The Company requests payments for its products and services at the point of sale. The Company generally does not enter 
into any long-term financing arrangements or payment plans with customers or contracts with customers that have non-
cash consideration.

Sales Taxes

Sales tax amounts collected from customers for remittance to governmental authorities are presented on a net basis in 
the Consolidated Statements of Operations.

Advertising

Advertising costs are generally charged to expense in the period incurred. Cooperative reimbursements from vendors are 
recorded in the period the related advertising expenditure is incurred. The Company classifies vendor consideration as a 
reduction to Cost of sales.

Equity-Based Compensation

The Company measures all equity-based payments using a fair-value-based method and records compensation expense 
over the requisite service period using the straight-line method in its Consolidated Financial Statements. The expense 
calculation includes estimated forfeiture rates which have been developed based upon historical experience.

Interest Expense

Interest expense is recognized in the period incurred at the applicable interest rate in effect. 

Foreign Currency Translation

The Company's functional currency is the US dollar. The functional currency of the Company's international operating 
subsidiaries is generally the same as the corresponding local currency. Assets and liabilities of the international operating 
subsidiaries  are  translated  at  the  spot  rate  in  effect  at  the  applicable  reporting  date.  Revenues  and  expenses  of  the 
international operating subsidiaries are translated at the average exchange rates in effect during the applicable period. 
The resulting foreign currency translation adjustment is recorded as Accumulated other comprehensive loss, which is 
reflected as a separate component of Stockholders' equity.

Income Taxes

Deferred income taxes are provided to reflect the differences between the tax bases of assets and liabilities and their 
reported amounts in the Consolidated Financial Statements using enacted tax rates in effect for the year in which the 
differences are expected to reverse. The Company performs an evaluation of the realizability of deferred tax assets on a 
quarterly basis. This evaluation requires management to make use of estimates and assumptions and considers all positive 
and negative evidence and factors, such as the scheduled reversal of temporary differences, the mix of earnings in the 
jurisdictions in which the Company operates, and prudent and feasible tax planning strategies.

The Company accounts for unrecognized tax benefits based upon its assessment of whether a tax benefit is more likely 
than not to be sustained upon examination by tax authorities. The Company reports a liability for unrecognized tax benefits 
resulting from unrecognized tax benefits taken or expected to be taken in a tax return and recognizes interest and penalties, 
if any, related to its unrecognized tax benefits in income tax expense.

The Tax Cuts and Jobs Act contains a provision which subjects a US parent of a foreign subsidiary to current US tax on 
its global intangible low-tax income (“GILTI”). The GILTI income is eligible for a deduction, which lowers the effective 
tax rate to 10.5% for taxable years 2018 through 2025 and 13.125% after 2025. The Company will report the tax impact 
of GILTI as a period cost when incurred. Accordingly, the Company is not providing deferred taxes for basis differences 
expected to reverse as GILTI.

Recent Accounting Pronouncements

Accounting for Hedging Activities

In August 2017, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 
2017-12, Derivatives and Hedging (Topic 815), intending to improve the transparency of information included in the 
financial statements by aligning cash flow and fair value hedge accounting with its risk management activities.  The ASU 
eliminates the requirement to separately measure and report hedge ineffectiveness for cash flow hedges and net investment 
hedges, and generally requires the entire change in the fair value of a hedging instrument to be presented in the same 
income statement line as the hedged item. The ASU also simplifies certain documentation and assessment requirements 
and will incorporate new disclosure requirements and amendments to existing disclosures. The Company elected to early 
adopt this standard during the fourth quarter of 2018. The adoption of this ASU did not have an impact on the Company's 
Consolidated Financial Statements.

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit 
Losses on Financial Instruments. This ASU introduces a new forward-looking approach, based on expected losses, to 
estimate credit losses on certain types of financial instruments, including trade receivables. The estimate of expected 
credit losses will require considerations of historical information, current information and reasonable and supportable 
forecasts. This ASU also expands the disclosure requirements to enable users of financial statements to understand the 
assumptions, models and methods for estimating expected credit losses. This ASU is effective for the Company beginning 
in the first quarter of 2020 and allows for early adoption beginning in the first quarter of 2019. The Company is currently 
evaluating the impact the ASU will have on its Consolidated Financial Statements.

Accounting for Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which, together with amendments issued during 
2018, requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by 
long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. This 
ASU is effective for the Company beginning in the first quarter of 2019 and allows for early adoption. Entities are required 
to  use  the  modified  retrospective  approach,  with  the  option  of  applying  the  requirements  of  the  standard  either  (1) 
retrospectively to each prior comparative reporting period presented or (2) retrospectively at the beginning of the period 
of adoption.

The Company established a cross-functional implementation team to analyze the effect of the ASU. The Company utilized 
a combination of a bottom-up and top-down approach to identify and analyze its lease portfolio. The analysis included 
reviewing all forms of leases, performing a completeness assessment over the lease population, assessing the policy 
elections offered by the standard and evaluating its business processes and internal controls to meet the ASU's accounting, 
reporting  and  disclosure  requirements. The  Company  adopted  the  standard  on  January  1,  2019  and  applied  it  at  the 
beginning of the period of adoption. Therefore, upon adoption, financial information and disclosures are not updated for 
comparative reporting periods under the new standard. Additionally, the Company has elected the transition package of 
practical  expedients  upon  adoption  which,  among  other  things,  allows  an  entity  to  not  reassess  the  historical  lease 
classification. 

The adoption of the standard impacts the Company's Consolidated Balance Sheet. The adoption of the standard results 
in the recognition of right-of-use assets and additional lease liabilities of approximately $81 million as of January 1, 2019, 
mainly related to operating leases for the Company's real estate portfolio. Along with the recognition of right-of-use 
assets and lease liabilities, the Company will be providing new disclosures for its leasing activities. The Company does 
not expect the adoption of the standard to impact the Consolidated Statements of Operations or the Consolidated Statements 
of Cash Flows. In addition, the standard will not have an impact on the Company's liquidity or debt covenant compliance 
under its current agreements.

December 1, 2018 Impairment Analysis

The Company completed its annual impairment analysis as of December 1, 2018. For all reporting units, the Company 
performed a qualitative analysis. The Company determined that it was more-likely-than-not that the individual fair values 
of all reporting units exceeded the respective carrying values. As a result of this determination, the quantitative impairment 
analysis  was  not  performed.  There  continues  to  be  substantial  uncertainty  regarding  the  economic  impact  of  the 
Referendum on the UK's Membership of the European Union ("EU") advising for the exit of the UK from the EU and 
the subsequent notice delivered by the UK to the EU of the UK's withdrawal (referred to as "Brexit"). Negotiations to 
determine the terms of the withdrawal, including the terms of trade between the UK and EU, are ongoing. The Company 
evaluated these facts when considering its qualitative analysis of the UK reporting unit and concluded it was more-likely-
than-not that the fair value of the UK reporting unit exceeds its carrying value.

December 1, 2017 Impairment Analysis

The Company completed its annual impairment analysis as of December 1, 2017. For the Corporate, Small Business and 
UK reporting units, the Company performed a qualitative analysis. The Company determined that it was more-likely-
than-not that the individual fair values of the Corporate, Small Business and UK reporting units exceeded the respective 
carrying values and therefore a quantitative impairment analysis was deemed unnecessary. The Company performed a 
quantitative  analysis  of  the  Public  and  Canada  reporting  units.  Based  on  the  results  of  the  quantitative  analysis,  the 
Company determined that the fair value of the Public and Canada reporting units exceeded their carrying values by 179%
and 153%, respectively, and no impairment existed.

6.  

Contract Liabilities and Remaining Performance Obligations

The Company's contract liabilities consist of payments received from customers, or such consideration that is contractually 
due, in advance of providing the product or performing services. The Company's contract liabilities are reported in a net 
position on a contract-by-contract basis at the end of each reporting period. As of December 31, 2018 and December 31, 
2017, the contract liability balance was $178 million and $159 million, respectively. For the year ended December 31, 
2018 and 2017, the Company recognized revenue of  $123 million and $113 million, respectively, related to its contract 
liabilities.

A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, 
the performance obligation is satisfied. For more information regarding the Company's performance obligations, see Note 
1 (Description of Business and Summary of Significant Accounting Policies). The following table represents the total 
transaction price for the remaining performance obligations as of December 31, 2018 related to non-cancelable contracts 
longer than 12 months in duration that is expected to be recognized over future periods.

The Company's indebtedness creates interest rate risk on its variable-rate debt. The Company uses derivative financial 
instruments  to  manage  its  exposure  to  interest  rate  risk.  The  Company  does  not  hold  or  issue  derivative  financial 
instruments for trading or speculative purposes.

The Company has interest rate cap agreements that entitle it to payments from the counterparty of the amount, if any, by 
which three-month LIBOR exceeds the strike rates of the caps during the agreement period in exchange for an upfront 
premium. During 2018, the Company entered into interest rate cap agreements with a combined notional value of $1.6 
billion resulting in premiums paid to the counterparties of $15 million. As of December 31, 2018 and December 31, 2017, 
the Company had the following interest rate cap agreements for which the fair values are classified within Other assets 
on the Consolidated Balance Sheets:

The fair value of the Company's interest rate cap agreements is classified as Level 2 in the fair value hierarchy. The 
valuation of the interest rate cap agreements is derived by using a discounted cash flow analysis on the expected cash 
receipts that would occur if variable interest rates rise above the strike rates of the caps. This analysis reflects the contractual 
terms of the interest rate cap agreements, including the period to maturity, and uses observable market-based inputs, 
including  LIBOR  curves  and  implied  volatilities.  The  Company  also  incorporates  insignificant  credit  valuation 
adjustments to appropriately reflect the respective counterparty's nonperformance risk in the fair value measurements. 
The counterparty credit spreads are based on publicly available credit information obtained from a third-party credit data 
provider. For additional details, see Note 9 (Long-Term Debt).

The interest rate cap agreements are designated as cash flow hedges. The changes in the fair value of derivatives that 
qualify as cash flow hedges are recorded in Accumulated other comprehensive loss and are subsequently reclassified into 
Interest expense in the period when the hedged forecasted transaction affects earnings. The Company recorded a $2 
million loss and an insignificant gain, net of tax, into Accumulated other comprehensive loss for the years ended December 
31, 2018 and 2017, respectively. During 2018 and 2017, the Company reclassified $5 million and an insignificant amount, 
respectively, from Accumulated other comprehensive loss to earnings within Interest expense, net on the Consolidated 
Statement of Operations. The Company expects to reclassify $4 million from Accumulated other comprehensive loss 
into Interest expense, net during the next 12 months.   

Prior to the election of hedge accounting treatment during the first quarter of 2017, the Company recognized less than $1 
million of Interest income in the Company's Consolidated Statement of Operations related to the changes in the fair value 
of the interest rate cap agreements.

British pound-denominated debt facilities. 

As of December 31, 2018, the Company is in compliance with the covenants under the various credit agreements and 
indentures.

Credit Facilities

The Company has a variable rate CDW UK revolving credit facility that is denominated in British pounds. As of December 
31, 2018, the Company could have borrowed up to an additional £50 million ($64 million at December 31, 2018) under 
the CDW UK revolving credit facility.

The Company also has a variable rate senior secured asset-based revolving credit facility (the "Revolving Loan") that is 
denominated in US dollars. The Revolving Loan is used by the Company for borrowings, issuances of letters of credit 
and floorplan financing. The Revolving Loan has less than $1 million of undrawn letters of credit, $393 million reserved 
for the floorplan sub-facility and a borrowing base of $1.8 billion which is based on the amount of eligible inventory and 
accounts receivable balances as of November 30, 2018. As of December 31, 2018, the Company could have borrowed 
up to an additional $1.1 billion under the Revolving Loan.

The Revolving Loan is collateralized by a first priority interest in inventory (excluding inventory to the extent collateralized 
under the inventory financing arrangements as described in Note 5 (Inventory Financing Agreements)), deposits, and 
accounts receivable, and a second priority interest in substantially all US assets.

Term Loans

The CDW UK term loan agreement has a variable interest rate. The Company is required to make annual principal 
installments of £5 million ($6 million at December 31, 2018), with the remaining principal amount due at the maturity 
date.

The CDW UK term loan agreement imposes restrictions on CDW UK's ability to transfer funds to the Company through 
the payment of dividends, repayment of intercompany loans, advances or subordinated debt that require, among other 

72

Table of Contents

CDW CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

things, the maintenance of a minimum net leverage ratio. As of December 31, 2018, the amount of restricted payment 
capacity under the CDW UK term loan was £128 million ($163 million at December 31, 2018).

The senior secured term loan facility (the "Term Loan") has a variable interest rate, which has effectively been capped 
through the use of interest rate caps (see Note 8 (Financial Instruments)). The interest rate disclosed in the table above 
represents the variable interest rates in effect for 2018 and 2017, respectively. The Company is required to pay quarterly 
principal installments of $4 million with the remaining principal amount due at the maturity date. As of December 31, 
2018, the amount of CDW's restricted payment capacity under the Term Loan was $1.5 billion.

The Term Loan is collateralized by a second priority interest in substantially all inventory (excluding inventory to the 
extent  collateralized  under  the  inventory  financing  arrangements  as  described  in  Note  5  (Inventory  Financing 
Agreements)), deposits and accounts receivable, and by a first priority interest in substantially all other US assets.

Senior Notes

The senior notes have a fixed interest rate, which is paid semi-annually. 

Debt Issuances and Extinguishments

On April 3, 2018, the Company amended the Term Loan, reducing interest margins by 25 basis points. Borrowings under 
the Term Loan continue to bear interest at a variable rate.

During 2017, the Company amended, extended and increased its prior revolving loan (the "Prior Revolving Loan") and 
recorded  a  loss  on  extinguishment  of  long-term  debt  of  $1  million in  the  Consolidated  Statement  of  Operations, 
representing a write-off of a portion of unamortized deferred financing costs. Fees of $4 million related to the Prior 
Revolving Loan were capitalized as deferred financing fees and are being amortized over the five-year term of the facility 
on a straight-line basis. These deferred financing fees are recorded in the Other assets line on the Consolidated Balance 
Sheets.

During 2017, the Company amended its prior $1.5 billion senior secured term loan facility (the "Prior Term Loan Facility") 
and recorded a loss on extinguishment of long-term debt of $14 million in the Consolidated Statement of Operations. 
This loss represented the write-off of a portion of the unamortized deferred financing fees of $5 million and unamortized 
discount related to the Prior Term Loan Facility of $9 million. In connection with the issuance of the Term Loan, the 
Company incurred and recorded $2 million in deferred financing fees.

During 2017, the Company completed the issuance of the 2025 Senior Notes at par. The proceeds from the issuance of 
the 2025 Senior Notes along with cash on hand and proceeds from Revolving Loan borrowings were deposited to redeem 
all of the then remaining $600 million aggregate principal amount of the 2022 Senior Notes. In connection with this 
redemption,  the  Company  recorded  a  loss  on  extinguishment  of  long-term  debt  of $43  million in  the  Consolidated 
Statement of Operations for the year ended December 31, 2017. This loss represents $37 million in redemption premium 
and $6 million for the write-off of the remaining deferred financing fees related to the 2022 Senior Notes.

On December 22, 2017, the Tax Cuts and Jobs Act was enacted into law. The Tax Cuts and Jobs Act changed several 
aspects of US federal tax law including: reducing the US corporate income tax rate from 35.0% to 21.0% beginning on 
January 1, 2018; applying a one-time tax on the deemed mandatory repatriation of the Company's unremitted foreign 
earnings which have not been subject to US tax; imposing a minimum US tax on foreign earnings; providing for the 
immediate  expensing  of  certain  qualified  property;  and  changing  the  tax  treatment  of  performance-based  executive 
compensation and certain employee fringe benefits. 

The SEC issued Staff Accounting Bulletin 118 allowing for provisional amounts to be recorded during a measurement 
period not to exceed one year. During the year ended December 31, 2017, the Company recorded provisional amounts 
for the impact of revaluing deferred tax assets and liabilities, the deemed mandatory repatriation tax on the Company's 
unremitted foreign earnings and the state income tax effects from the changes in federal tax law during the year. The 
Company adjusted the US federal and state provisional amounts during 2018, recording a net tax benefit of $2 million. 
The adjustment was primarily  driven by the rate differential on adjustments to temporary book-tax differences made in 
finalizing the 2017 federal income tax return and finalizing the deemed mandatory repatriation tax on the Company's 
unremitted foreign earnings.

The Company has state and international income tax net operating losses of $11 million, which will expire at various 
dates from 2026 through 2032 and state and international tax credit carryforwards of $25 million, which expire at various 
dates from 2021 through 2027.

Due to the nature of the CDW UK acquisition, the Company has provided US income taxes of $19 million on the excess 
of the financial reporting value of the investment over the corresponding tax basis. The Company is indefinitely reinvested 
in its UK business, and therefore will not provide for any US deferred taxes on the earnings of the UK business. The 
Company is not permanently reinvested in its Canadian business and therefore has recognized deferred tax liabilities of 
$3 million as of December 31, 2018 related to withholding taxes on earnings of its Canadian business. 

In the ordinary course of business, the Company is subject to review by domestic and foreign taxing authorities, including 
the Internal Revenue Service ("IRS"). In general, the Company is no longer subject to audit by the IRS for tax years 
through 2014 and state, local or foreign taxing authorities for tax years through 2013. Various taxing authorities are in

the process of auditing income tax returns of the Company and its subsidiaries. The Company does not anticipate that 
any adjustments from the audits would have a material impact on its consolidated financial position, results of operations 
or cash flows.

Changes in the Company's unrecognized tax benefits at December 31, 2018, 2017 and 2016 were as follows:

As of December 31, 2018, the Company had $15 million of unrecognized tax benefits that, if recognized, would have 
decreased  income  taxes  and  the  corresponding  effective  income  tax  rate  and  increased  net  earnings. The  impact  of 
recognizing these tax benefits, net of the federal income tax benefit related to unrecognized state income tax benefits, 
would be approximately $12 million.

Stockholders' Equity

Share Repurchase Program

The Company has a share repurchase program under which it may repurchase shares of its common stock in the open 
market or through privately negotiated other transactions, depending on share price, market conditions and other factors. 
The share repurchase program does not obligate the Company to repurchase any dollar amount or number of shares, and 
repurchases may be commenced or suspended from time to time without prior notice. 

During 2018, the Company repurchased 6.3 million shares of its common stock for $522 million. These repurchases 
occurred under the program announced on August 3, 2017, by which the Board of Directors authorized a $750 million  
increase to the Company's share repurchase program. As of December 31, 2018, the Company has $336 million remaining 
under this program.

2013 Long-Term Incentive Plan

The 2013 Long-Term Incentive Plan ("2013 LTIP") provides for the grant of incentive stock options, nonqualified stock 
options,  stock  appreciation  rights,  restricted  stock,  restricted  stock  units,  bonus  stock  and  performance  awards. The 
maximum aggregate number of shares that may be issued under the 2013 LTIP is 15,500,000 shares of the Company's 
common stock, in addition to the 3,798,508 shares of restricted stock granted in exchange for unvested Class B Common 
Units in connection with the Company's IPO. As of December 31, 2018, 4,978,336 shares were available for issuance 
under the 2013 LTIP, which was approved by the Company's pre-IPO shareholders. Authorized but unissued shares are 
reserved for issuance in connection with equity-based awards.

Stock Options

CDW CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The exercise price of a stock option granted is equal to the fair value of the underlying stock on the date of the grant. 
Stock options have a contractual term of 10 years and generally vest ratably over three years. To estimate the fair value 
of options granted, the Company uses the Black-Scholes option pricing model. The weighted-average assumptions used 
to value the stock options granted were as follows:

Equity Awards Granted by Seller of CDW UK

During 2018, 456,613 stock options granted by one of the sellers of CDW UK to certain CDW UK coworkers as part of 
the Company's acquisition of CDW UK vested. These equity awards had a weighted-average grant-date fair value of 
$35.93 per option. In connection with the exercise of such options, the seller of CDW UK distributed shares of common 
stock to each participant and withheld the number of shares of common stock equal to the respective tax withholding for 
each participant. The seller of CDW UK then transferred such withheld shares to the Company to satisfy the tax withholding 
for participants. The Company was required to pay withholding taxes of $19 million to Her Majesty's Revenue and 
Customs taxing authority related to the exercise of these options. This amount is reported as a financing activity in the 
Consolidated  Statement  of  Cash  Flows  and  as  an  increase  to Accumulated  Deficit  in  the  Consolidated  Statement  of 
Stockholders' Equity for the year ended December 31, 2018.

Earnings Per Share

The numerator for both basic and diluted earnings per share is Net income. The denominator for basic earnings per share

Coworker Retirement and Other Compensation Benefits

Profit Sharing Plan and Other Savings Plans

The Company has a profit sharing plan that includes a salary reduction feature established under the Internal Revenue 
Code Section 401(k) covering substantially all coworkers in the US. In addition, coworkers outside the US participate 
in other savings plans. Company contributions to the profit sharing and other savings plans are made in cash and determined 
at the discretion of the Board of Directors. For the years ended December 31, 2018, 2017 and 2016, the amounts expensed 
for these plans were $34 million, $20 million and $23 million, respectively.

Coworker Stock Purchase Plan

The Company has a Coworker Stock Purchase Plan (the "CSPP") that provides the opportunity for eligible coworkers to 
acquire shares of the Company's common stock at a 5% discount from the closing market price on the final day of the 
offering period. There is no compensation expense associated with the CSPP.

Commitments and Contingencies

The  Company  is  party  to  various  legal  proceedings  that  arise  in  the  ordinary  course  of  its  business,  which  include 
commercial, intellectual property, employment, tort and other litigation matters. The Company is also subject to audit by 
federal,  state,  international,  national,  provincial  and  local  authorities,  and  by  various  partners,  group  purchasing 
organizations and customers, including government agencies, relating to purchases and sales under various contracts. In 
addition, the Company is subject to indemnification claims under various contracts. From time to time, certain customers 
of the Company file voluntary petitions for reorganization or liquidation under the US bankruptcy laws or similar laws 
of the jurisdictions for the Company's business activities outside of the US. In such cases, certain pre-petition payments 
received by the Company could be considered preference items and subject to return to the bankruptcy administrator.

As of December 31, 2018, the Company does not believe that there is a reasonable possibility that any material loss 
exceeding the amounts already recognized for these proceedings and matters, if any, has been incurred. However, the 
ultimate resolutions of these proceedings and matters are inherently unpredictable. As such, the Company's financial 
condition and results of operations could be adversely affected in any particular period by the unfavorable resolution of 
one or more of these proceedings or matters.

16. 

Segment Information

The Company's segment information is presented in accordance with a "management approach," which designates the 
internal reporting used by the Chief Operating Decision-Maker for deciding how to allocate resources and for assessing 
performance. 

The  Company  has three reportable  segments:  Corporate,  which  is  comprised  primarily  of  private  sector  business 
customers with more than 250 employees in the US, Small Business, primarily servicing private sector business customers 
with up to 250 employees in the US, and Public, which is comprised of government agencies and education and healthcare 
institutions in the US. The Company has two other operating segments: CDW UK and CDW Canada, both of which do 
not meet the reportable segment quantitative thresholds and, accordingly, are included in an all other category ("Other"). 

The Company has centralized logistics and headquarters functions that provide services to the segments. The logistics 
function includes purchasing, distribution and fulfillment services to support the Corporate, Small Business and Public 
segments. As a result, costs and intercompany charges associated with the logistics function are fully allocated to both 
of these segments based on a percent of Net sales. The centralized headquarters function provides services in areas such 
as accounting, information technology, marketing, legal and coworker services. Headquarters function costs that are not 
allocated to the segments are included under the heading of "Headquarters" in the tables below. 

The Company allocates resources to and evaluates performance of its segments based on Net sales, Operating income 
and Adjusted EBITDA, a non-GAAP measure as defined in the Company's credit agreements. However, the Company 
has concluded that Operating income is the more useful measure in terms of discussion of operating results, as it is a 
GAAP measure.

Segment information for Total assets and capital expenditures is not presented, as such information is not used in measuring 
segment performance or allocating resources between segments.

The 2023 Senior Notes, the 2024 Senior Notes and the 2025 Senior Notes are, and, prior to being redeemed in full, the 
2022 Senior Notes were, guaranteed by the Parent and each of CDW LLC's direct and indirect, 100% owned, domestic 
subsidiaries (the "Guarantor Subsidiaries"). All guarantees by the Parent and the Guarantor Subsidiaries are and were 
joint and several, and full and unconditional; provided that guarantees by the Guarantor Subsidiaries (i) are subject to 
certain customary release provisions contained in the indentures governing the 2023 Senior Notes, the 2024 Senior Notes 
and  the  2025  Senior  Notes  and  (ii)  were  subject  to  certain  customary  release  provisions  contained  in  the  indenture 
governing the 2022 Senior Notes until such indenture was satisfied and discharged during 2017. CDW LLC's 100%

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company's management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, 
has evaluated the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rule 13a-15(e) 
or Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) as of the end of the period covered 
by this report. Based on such evaluation, the Company's management, including the Company's Chief Executive Officer and Chief 
Financial Officer, has concluded that, as of the end of such period, the Company's disclosure controls and procedures were effective 
in recording, processing, summarizing, and reporting, on a timely basis, information required to be disclosed by the Company in 
the reports that it files or submits under the Exchange Act, and that information is accumulated and communicated to the Company's 
management,  including  the  Company's  Chief  Executive  Officer  and  Chief  Financial  Officer,  as  appropriate  to  allow  timely 
discussions regarding required disclosure.

Management's Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined 
in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. Because of its inherent limitations, internal control over financial reporting 
may not prevent or detect misstatements and can provide only reasonable assurance with respect to financial statement preparation 
and presentation. 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 policies or procedures may deteriorate.

Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 
2018. Management based this assessment on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO) in "Internal Control — Integrated Framework (2013 framework)." 

Based on its assessment, management concluded that, as of December 31, 2018, the Company's internal control over 

financial reporting is effective.

Ernst & Young LLP, independent registered public accounting firm, has audited the Consolidated Financial Statements 

of the Company and the Company's internal control over financial reporting and has included their reports herein.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting during the quarter ended December 31, 2018

that have materially affected or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of CDW Corporation and subsidiaries  

Opinion on Internal Control over Financial Reporting 

We have audited CDW Corporation and subsidiaries' internal control over financial reporting as of December 31, 2018, based on 
criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway Commission (2013 framework) (the COSO criteria). In our opinion, CDW Corporation and subsidiaries (the Company) 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on the 
COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, and the related consolidated 
statements of operations, comprehensive income, stockholders' equity and cash flows for each of the three years in the period 
ended December 31, 2018, and the related notes and the financial statement schedule listed in the Index at Item 15 (a) (2) and our 
report dated February 27, 2019 expressed an unqualified opinion thereon. 

Basis for Opinion 

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment 
of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on 
Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over 
financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material 
respects.  

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing 
such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for 
our opinion. 

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 accepted 
accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets 
of the company; (2) 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 (3) 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.

Forward-looking Statements
Statements in this annual report that are not statements 
of historical fact are forward-looking statements within the 
meaning of the federal securities laws, including without limitation 
statements regarding the future financial performance of CDW. 
These statements involve risks and uncertainties that may cause 
actual results to differ materially from those described in such 
statements. Important factors that could cause actual results 
to differ materially from CDW’s expectations, or cautionary 
statements, are disclosed under the section entitled “Risk  
Factors” included in CDW’s Annual Report on Form 10-K for  
the year ended December 31, 2018 (the “Form 10-K”). Refer  
to page 3 of the Form 10-K for additional information. CDW 
undertakes no obligation to publicly update or revise any  
forward-looking statement as a result of new information,  
future events or otherwise, except as required by law. 

Use of Non-GAAP Financial Measures
Earnings before interest, taxes and depreciation and amortization 
(“EBITDA”), Adjusted EBITDA, Adjusted EBITDA margin, Non-
GAAP net income and Non-GAAP net income per diluted share 
are not based on generally accepted accounting principles in the 
United States (“non-GAAP”). CDW believes these non-GAAP 
financial measures provide helpful information with respect to 
the underlying operating performance of CDW’s business, as 
they remove the impact of items that management believes are 
not reflective of underlying operating performance. Additionally, 
Adjusted EBITDA is a measure in the credit agreement governing 
CDW’s senior secured term loan facility. A reconciliation of 
Adjusted EBITDA to net income is included on page 25 of the  
Form 10-K, and a reconciliation of non-GAAP net income  
(which is divided by fully diluted, weighted-average common 
shares outstanding of 153.6 million in 2018, 158.2 million in 2017,  
166.0 million in 2016, 171.8 million in 2015, 172.8 million in 2014  
and 158.7 million in 2013 to arrive at non-GAAP net income per 
diluted share for those periods) to net income is included on  
page 26 of the Form 10-K. Reconciliations for these financial 
measures are also included on the investor relations section of the 
company website at www.cdw.com. Non-GAAP measures used by 
CDW may differ from similar measures used by other companies, 
even when similar terms are used to identify such measures.
