Chairman’s Letter 

Dear Fellow Stockholders,

Our more than 250,000 customers are focused on the results 

that matter to them. Representing public and private sectors 

and every major industry, their end-goals vary, but they all 

have one thing in common. Information technology, in one way 

or another, is critical to their ability to achieve their goals, and 

technology solutions are changing at a dizzying pace. Keeping 

up with all of it, wading through the complexity, managing risk 

and identifying the right partners and solutions can be daunting. 

That’s where CDW comes in. In an incredibly dynamic industry, 

we never stand still. We evolve–our capabilities, our offerings, 

our expertise–with the needs of our customers, and that is 

key to the value we deliver. With CDW, customers can focus on 

their priorities while we make technology work for them. We 

understand our customers’ objectives, the challenges they face 

and how IT can best enable their success. We cut through the 

complexity. We identify the right partners and build the most 

effective and efficient solutions to meet our customers’ unique 

needs. We orchestrate IT. 

In 2017, we delivered yet again for our customers, our  

partners, our stockholders and our coworkers. Our nimble 

business model, diverse product suite and balanced portfolio of 

end markets enabled us to deliver strong financial performance 

in 2017. For the year, net sales increased 8.7 percent, adjusted 

EBITDA increased 6.1 percent and non-GAAP earnings per share 

increased 11.7 percent. 

Our nimble business model enabled us to pivot to capture 

growth opportunities driven by four customer trends. The  

first–customer focus on hardware refresh–was driven by 

renewed confidence in the economy. Customers’ determination 

to have the most secure IT strategy possible led to the second 

trend–a focus on security. The third trend was the adoption 

of more flexible architectures to enable customers to handle 

growth efficiently. And, the fourth was an ongoing trend of more 

and more solutions being delivered via software. Our results 

show our success in capitalizing on these trends. 

Thomas E. Richards
Chairman, President and Chief Executive Officer

In an incredibly dynamic industry, 
we never stand still. We evolve–
our capabilities, our offerings, our 
expertise–with the needs of our 
customers, and that is key to the 
value we deliver. 

CDW CORPORATION  1

Chairman’s Letter  (continued)

Our diverse product suite of more than 100,000 products  

from over 1,000 leading and emerging brands ensured we were 

well positioned to meet customers’ evolving needs and market 

trends. In 2017, we saw balanced growth across Hardware, 

Software and Services. 

The final driver of our performance was the power of our 

balanced portfolio of end markets. We have five US channels, 

each with over $1 billion in 2017 net sales and an additional  

$1 billion plus from our UK and Canadian operations. The 

diversity of these end markets enables us to consistently 

deliver overall profitable growth regardless of macro and 

exogenous impacts on the business.  

In addition to our financial achievements in 2017, we made 

excellent progress executing our three-part strategy for  

growth. Examples of progress in our first strategy, to capture 

share and acquire new customers, included the evolution of 

our go-to-market model to better serve small businesses; 

enhancement of our international capabilities to further  

support our sellers’ ability to provide solutions to customers 

outside their domestic markets; and piloting of AMANDA, 

an automated digital assistant designed to take many 

administrative tasks, like fulfilling requests for quotes and 

providing order status, off an account manager’s plate. 

Examples of progress in our second strategy, to enhance our  

capabilities in high-growth solutions areas, include the creation  

and launch of an artificial intelligence tool to identify customers 

with the highest propensity to purchase hyper-converged 

infrastructure; joint CDW and partner ‘security thought 

leadership’ sessions across the US; and the addition of 

coworkers focused on providing analytics and information 

management solutions for customers.

Lastly, for our third strategy, to continue expanding our 

integrated, value-added services, examples include bringing  

our Device-as-a-Service offering to market; launching a 

custom services recommendation engine that identifies  

the most relevant services and provides an immediate price 

quote; and expanding our Cloud Planning Services to include  

‘micro consulting engagements.’  

Our diverse product suite of more than 
100,000 products from over 1,000 leading  
and emerging brands ensured we were 
well positioned to meet customers’ evolving 
needs and market trends. In 2017, we 
saw balanced growth across Hardware, 
Software and Services. 

2  CDW CORPORATION

In 2017, we continued to invest in our partners and coworkers  

as well. We added more than 80 new partners, many in  

high-growth areas such as end-point security, video and  

cloud. We also added 125 customer-facing coworkers in 2017 

with more than half in technical roles supporting sellers. 

I want to thank our 8,700 coworkers for their incredible 

commitment, hard work and dedication to our customers and 

CDW in 2017. They truly are our secret weapon. And, for that 

reason, we were very pleased to be able to invest a portion 

of the benefit from the 2017 Tax Cuts and Jobs Act in our 

coworkers. We made a one-time Coworker Equity Grant  

valued at $12 million to all non-executive coworkers and a 

$1,000 cash bonus to all of our hourly and frontline coworkers. 

These investments were designed both to recognize the 

contribution each and every one of our coworkers makes 

to meeting our customers’ needs and drive alignment with 

shareholders further into the organization. 

Looking ahead, we remain committed to aggressively pursuing 

our vision of being the leading IT solutions and services provider 

in the markets we serve. We will continue to invest to deepen 

our relationships with customers and ensure our expertise and 

capabilities evolve to meet their ever-changing needs. I have no 

doubt in 2018, with relentless focus and strong execution, CDW 

will again deliver profitable growth, outpace the market, stay 

ahead of our competitors and return value to shareholders.

Thank you for your continued confidence in CDW.

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”), Canada, and the United Kingdom (“UK”). 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 $925 billion in sales in 2017. We believe our addressable markets in the US, UK 
and Canada represent approximately $300 billion in annual sales. These are highly fragmented markets served by thousands of 
IT resellers and solutions providers. For the year ended December 31, 2017, we estimate that our total Net sales of $15 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.

Our value proposition to our customers

Our value proposition to our vendor partners

Broad selection of products and multi-branded IT
solutions

Access to over 250,000 customers

Value-added services with integration capabilities

Large and established customer channels

Highly-skilled specialists and engineers

Strong distribution and implementation capabilities

Solutions across a very broad IT landscape

Value-added solutions and marketing programs that
generate end-user demand

Customers

We  provide  integrated  IT  solutions  to  over  250,000  small,  medium  and  large  business,  government,  education  and 

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 
and  highly  skilled  service  delivery  engineers.  Our  market  segmentation  allows  us  to  customize  our  offerings  and  to  provide 
enhanced expertise in designing and implementing IT solutions that meet our customer’s specific needs. 

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 2017. Net sales to customers in the UK and Canada combined generated $1.6 billion in 2017.  We believe this diversity of 

4

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.

For further information regarding our segments, including financial results, see Note 18 (Segment Information) to the 

accompanying Consolidated Financial Statements under Item 8, “Financial Statements and Supplementary Data.” 

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, Snow, Splunk, Veeam, Viptella and WidePoint. 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 2017, 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 and Microsoft, 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, 
2017. Purchases from our three largest wholesale distributors, Ingram Micro, SYNNEX and Tech Data, are each approximately 
10% of total 2017 purchases. 

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  represent 
approximately 50% of total consolidated 2017 Net sales, of which approximately 25% relate to electronic delivery for software 
licenses.

5

 
 
Table of Contents

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 in which we compete 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. With the acquisition of CDW UK in 2015, 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 2017 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 
their goals, 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, for both on and off-premise solutions, 
enables us to provide a well-integrated solution, including converged and hyper-converged infrastructure, physical and 
virtualized servers, software defined data center, storage and energy-efficient power and cooling.

Digital  Workspace:  We  build  end-to-end  solutions,  using  hardware,  software  and  services,  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,  and  utilize  solutions  to  unite

collaboration and applications.  We do this through 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 the security needs of our customers and provide them with risk mitigation tools and services 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 and development of security roadmaps.

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 commercial and business organizations.  
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, 2017, we employed 8,726 coworkers with approximately 7,200 coworkers in the US, 1,100 in the 
UK and 400 in Canada. Approximately two thirds of our coworkers at year-end 2017 were customer facing. Over half of our Net 
sales are generated by account managers who have greater than seven years of experience. 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, British and Canadian 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”). CDW Corporation continued as the surviving corporation and same legal entity after the 
acquisition, but became a wholly owned subsidiary of VH Holdings, Inc., a Delaware corporation.

In July 2013, CDW Corporation completed the IPO of its common stock.

After the IPO, through secondary offerings and fund distributions, Madison Dearborn and Providence Equity liquidated 

their previous ownership positions in CDW.

Table of Contents

 In November 2014, we completed the acquisition of a 35% non-controlling equity interest in UK-based IT solutions 
provider, Kelway TopCo Limited (“Kelway”). In August 2015, we purchased the remaining 65% of Kelway’s outstanding common 
stock, which increased our ownership interest from 35% to 100% and provided us control. Rebranded CDW UK in April 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. Financial results of CDW UK are included in our Consolidated Financial Statements from the date 
of acquisition.

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 (referred to as “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.

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 are impacted by government spending policies, budget priorities and revenue 
levels. An adverse change in government spending policies (such as budget cuts or limitations), budget priorities or revenue levels 
could cause our public sector customers to reduce their purchases or to terminate or not renew their contracts with us, which could 
adversely affect our business, results of operations or cash flows. For example, in 2013, as a result of sequestration and related 
budget uncertainty and the partial shutdown of the US federal government for 16 days, we experienced significantly reduced US 
Federal sales in our Public segment.

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

We purchase products for resale from vendor partners, which include OEMs and software publishers, and wholesale 
distributors. For the year ended December 31, 2017, we purchased approximately 50% of the products we sold directly from 
vendor partners and the remaining amount from wholesale distributors for our North American operations. We are authorized by 
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 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.

Table of Contents

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 
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. 

Although we purchase from a diverse vendor base, in 2017, 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 2017 consolidated Net 
sales. Sales of products manufactured by Cisco and HP Inc. represented over 25% of our 2017 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 leading to manufacturer allocation, 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 SaaS, Infrastructure as a Service (“IaaS”) and Platform 
as a Service (“PaaS”), Device as a Service (“DaaS”) and the Internet of Things (“IoT”). 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, or the lack of 
acceptance of innovations or delays in technology spending by 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. In addition, 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 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;

large service providers and system integrators, such as Accenture, Dell, Hewlett Packard Enterprise and IBM;

communications service providers, such as AT&T, CenturyLink and Verizon; 

cloud providers, such as Amazon Web Services, Box and Microsoft; 

e-tailers, such as Amazon, Newegg and TigerDirect.com; and

• 

retailers (including their e-commerce activities), such as Office Depot and Staples.

We expect the competitive landscape to continue to evolve as new technologies are developed, such as cloud-based 
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 technologies that deliver 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 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 also 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 risk of 
breaches in security and other illegal or fraudulent acts, including cyberattacks. The evolving nature of such threats, in light of 
new  and  sophisticated  methods  used  by  criminals  and  cyberterrorists,  including  computer  viruses,  malware,  phishing, 
misrepresentation, social engineering and forgery, are making it increasingly challenging to anticipate and adequately mitigate 
these risks. 

11

 
Table of Contents

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 and the Medicare and Medicaid Anti-Kickback Statute or similar laws of the jurisdictions 
for  our  business  activities  outside  of  the  US)  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 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 fail to provide high-quality services to our customers, or if 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, 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 Thomas E. Richards, our Chairman and 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. 

Our inability to attract, develop, engage and retain key personnel could have an adverse effect on our relationships with 
our vendor partners and customers and adversely affect our ability to expand our offerings of value-added services and solutions. 
Moreover, our inability to train our sales, services and technical personnel effectively to meet the rapidly changing technology 
needs of our customers could cause a decrease in the overall quality and efficiency of such personnel. 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.

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 that could also cause disruptions 
to our supply chain include: 

• 

• 

• 

• 

• 

• 

• 

the imposition of additional trade law provisions or regulations;

the imposition of additional duties, tariffs and other charges on imports and exports;

foreign currency fluctuations;

natural disasters or other adverse occurrences at, or affecting, any of our suppliers’ facilities;

restrictions on the transfer of funds;

the financial instability or bankruptcy of manufacturers; and

significant labor disputes, such as strikes.

We cannot predict whether the countries in which the products we sell are purchased or manufactured, or may be purchased 
or manufactured in the future, 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, as well as foreign labor strikes 
and work stoppages or boycotts, 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,  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 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, the risk of which is heightened during periods of economic downturn or uncertainty or, in the case of 
public sector customers, during periods of budget constraints. 

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 
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 

13

Table of Contents

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. These bulk purchases could increase our exposure to 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 
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. 

14

Table of Contents

We also are subject to proceedings, investigations and audits by federal, state, international, national, provincial and local 
authorities, including because 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 US and foreign 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 US and foreign laws and regulations in a number of areas including 
areas  of  labor  and  employment,  advertising,  e-commerce,  tax,  import  and  export  requirements,  anti-corruption,  data  privacy 
requirements  (including  those  under  the  European  Union  General  Data  Protection  Regulation),  anti-competition,  and 
environmental, 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.  For example, the Tax Cuts and Jobs Act of 2017 was signed into law in the fourth quarter of 2017, making significant 
changes to the US Internal Revenue Code.  While we have estimated the income tax effects of the Act in our Consolidated Financial 
Statements, we continue to analyze the income tax effects of the Act, as well as to monitor tax and accounting guidance issued by 
various authorities, which could result in material changes as we refine those estimates. Furthermore, the laws and regulations to 
which the Company is subject 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, 2017, we had $3.2 billion of total long-term debt 
outstanding, as defined by GAAP, and $498 million of obligations outstanding under our inventory financing agreements, and the 
ability to borrow an additional $996 million under our senior secured asset-based revolving credit loan facility (the “Revolving 
Loan”) and an additional £50 million ($68 million at December 31, 2017) 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;

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

15

Table of Contents

• 

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;

create liens;

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 $1.5 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, 2017 was $1.6 billion and, therefore, did not restrict our ability to borrow under our Revolving Loan as of 
that date. 

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) 
16

Table of Contents

$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, 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, 2017, we had $996 million 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 $454 
million of reserves related to our floorplan sub-facility) and an additional £50 million ($68 million at December 31, 2017) 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, 2017, 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 
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 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.

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 
18

Table of Contents

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 $0.21 per share per quarter, 
or $0.84 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, 2017, we owned or leased a total of 2.3 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, 2017, 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.

On October 29, 2015, the Company learned of an investigation by the SEC of the Company’s vendor partner program 
incentives. On May 19, 2017, the SEC Staff informed the Company that the SEC has concluded its investigation and does not 
intend to recommend an enforcement action. The investigation did not have any impact on the Company’s financial condition or 
results of operations other than customary costs related to the Company’s cooperation with the investigation.

Holders

As of February 23, 2018, there were 24 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, 2018, we announced that our Board of Directors declared a quarterly cash dividend on our common stock 
of $0.21 per share. The dividend will be paid on March 12, 2018 to all stockholders of record as of the close of business on 
February 26, 2018. 

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 
10 (Long-Term Debt) to the accompanying Consolidated Financial Statements.

Issuer Purchases of Equity Securities

On May 4, 2016, we announced that our Board of Directors authorized a $750 million increase to our previously announced 
$500 million 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 August 3, 2017, we 
announced that our Board of Directors authorized another $750 million increase to our share repurchase program. As of the year 
ended December 31, 2017, we have $858 million remaining under this program.

Includes capitalized lease obligations of $1 million and $2 million as of December 31, 2017 and 2016, respectively, which 
are included in Other liabilities on the Consolidated Balance Sheet.

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 
(“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 10 (Long-Term Debt) to the accompanying Consolidated Financial Statements.

The following unaudited table sets forth reconciliations of net income to EBITDA and EBITDA to Adjusted EBITDA 
for the periods presented:

Non-GAAP net income excludes, among other things, charges related to the amortization of acquisition-related intangible 
assets,  non-cash  equity-based  compensation,  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. 

In August 2015, we acquired CDW UK, which enhanced our ability to provide IT solutions to US based customers with 
multinational locations.  It also extended our footprint into the United Kingdom. Financial results of CDW UK are included in 
our Consolidated Financial Statements from the date of acquisition. 

We have three reportable segments, Corporate, Small Business and Public. Our Corporate segment primarily serves 
private sector business customers with more than 250 employees. Our Small Business segment primarily serves 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: Canada and CDW UK, 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 

29

Table of Contents

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 is 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.

Trends and Key Factors Affecting our Financial Performance

• 

• 

• 

• 

• 

• 

• 

We believe the following trends and key factors may have an important impact on our financial performance:

General economic conditions are a key factor affecting our ability to generate sales and achieve our targeted operating 
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. 

Changes in spending policies, budget priorities and revenue levels are a key factor influencing government purchasing 
levels. Our Government results also reflect increased interest in meeting public safety needs through technology solutions 
by State and Local customers, as well as our ability to address strategic changes made by the Federal government toward 
a more programmatic technology strategy.

Customer focus on security has been, and we expect will continue to be, an ongoing trend.  Customers are seeking solutions 
to protect their internal systems against threats and are implementing solutions that provide enterprise-wide visibility, 
detection expertise and investigation workflows. They are also implementing endpoint security, firewall segmentation 
and user authentication tools. 

The Healthcare industry continues to experience uncertainty given recent proposed legislative action and concerns related 
to funding, which is impacting healthcare spending as customers seek more clarity.

Our Education sales channel performance continues to benefit from the creation of new learning environments for students. 
It has also been positively affected by the implementation of networking projects related to the US Federal Communications 
Commission E-Rate program. Within the higher education market, networking projects continue to be a key priority 
across campuses. While technology is an opportunity to create cost savings and improve productivity, funding is a key 
determinant of technology spending in education.

There continues to be substantial uncertainty regarding the impact of the Referendum on the United Kingdom’s (“UK”) 
Membership of the European Union (“EU”), advising for the exit of the UK from the EU (referred to as “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.

Technology trends drive customer purchase behaviors and we are seeing continuing evolution in the market.  Innovation 
influences  customer  purchases  across  all  of  our  customer  end-markets.  Key  trends  in  technology  include  increasing 
adoption of cloud-based solutions for certain key workloads, including backup and recovery, collaboration and security, 
as well as adoption of hyper-converged appliances to deliver greater flexibility and efficiency. In addition, hybrid IT 
solutions are being adopted, along with software being embedded into solutions.

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.

Table of Contents

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 (“Term Loan”), which is 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 10 (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”.

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

Amounts have been recast for 2016 to present Small Business as its own operating and reportable segment.

Total Net sales in 2017 increased $1,210 million, or 8.7%, to $15,192 million, compared to $13,982 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 $1,238 million, or 8.9%, to $15,192 million, compared to $13,954 million for the year ended 
December 31, 2016.

Table of Contents

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 the year, 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 $457 million, or 7.8%, 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 $106 million, or 9.3%, compared to 2016. Sales growth was 

primarily driven by customer refresh of client devices and video.

Public segment Net sales in 2017 increased $448 million, or 8.0%, 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  2.9%,  reflecting  continued  customer  uncertainty  related  to  reimbursements  and 
funding.

Net sales in Other for 2017 increased $198 million, or 14.5%, compared to 2016. Other is comprised of results from our 
Canadian and UK operations. Both operations had strong growth in local currency as we continued to take share in the local 
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 $123  million, or 5.3%, to  $2,450 million in 2017, compared to $2,327 million in 2016. As a 
percentage of Net sales, Gross profit decreased 50 basis points to 16.1% in 2017, down from 16.6% 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,  net  service  contract  revenue, 
commission revenue, 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 costs, including sales commissions, year over year, primarily due to higher 
Gross profit, as well as higher coworker costs between years 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 9.3% in 2017, down

from 9.6% in 2016.

Segment income from operations 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.

Amounts have been recast for 2016 to present Small Business as its own operating and reportable segment.

Includes Headquarters’ function costs that are not allocated to the segments.

Income from operations was $866 million in 2017, an increase of $47 million, or 5.7%, compared to $819 million in 
2016. Although Income from operations increased, total operating margin percentage decreased 20 basis points to 5.7% in 2017, 
from 5.9% 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 Income from operations was $487 million in 2017, an increase of $33 million, or 7.4%, compared to 
$454 million in 2016. Corporate segment operating margin remained flat at 7.7% for 2017 and 2016. Although Income from 
operations 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 Income from operations was $74 million in 2017, an increase of $5 million, or 8.0%, compared 
to $69 million in 2016. Income from operations increased due to an increase in sales volume, while operating margin remained 
flat at 6.0% for 2017 and 2016.  The flat operating margin percentage reflects higher hardware sales and an ongoing competitive 
marketplace, which were fully offset by lower sales payroll expenses.

Public segment Income from operations was $374 million in 2017, an increase of $6 million, or 1.6%, compared to $368 
million in 2016. Public segment operating margin decreased 40 basis points to 6.2% in 2017, from 6.6% 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 Income from operations was $58 million in 2017, an increase of $14 million, or 32.8%, compared to $44 million
in 2016. Other Income from operations increased primarily due to higher sales volumes and Gross profit as we continue to take 
share in the local markets. Other operating margin percentage increased 50 basis points to 3.7% in 2017, from 3.2% 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.

Net loss on extinguishments of long-term debt

For  information  regarding  our  debt,  see  Note  10  (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 compared to $2 million in 
2016.

Income tax expense

On December 22, 2017, the Tax Cuts and Jobs Act was enacted into law. The Tax Cuts and Jobs Act changes 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.  We continue to analyze the income tax effects of the Tax Cuts and Jobs Act, as well as monitor guidance 
from the Internal Revenue Service and the US Treasury Department. Any additional income tax effects of the Tax Cuts and Jobs 
Act are expected to be recorded within the measurement period.

Income tax expense was $137 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. We expect to have an effective tax rate of between 24% and 25% in 2018. The 2018 effective tax rate may change 
due to various factors including: adjustments we make to the estimates of the impact of the Tax Cuts and Jobs Act that were 
recorded as of December 31, 2017, as well as additional guidance that the Internal Revenue Service, US Treasury Department and 
state taxing authorities may issue, changes in the estimated excess tax benefits due to the changes in the market value of our 
common stock and changes in the number of awards vesting and changes in state tax laws.

35

Table of Contents

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. 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.

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, 2017 and 2016 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 associated taxes, gains and losses from the 
extinguishment of debt and integration expenses. 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 
10 (Long-Term Debt) to the accompanying Consolidated Financial Statements.

Non-GAAP income before income taxes and Non-GAAP net income

Non-GAAP net income was $606 million for the year ended December 31, 2017, an increase of $37 million, or 6.5%, 

compared to $569 million for the year ended December 31, 2016.

There were 254 selling days for the years ended December 31, 2016 and 2015.

Amounts have been recast to present Small Business as its own operating and reportable segment.

Total  Net  sales  in 2016  increased $993  million,  or 7.6%,  to $13,982  million,  compared  to $12,989  million in 2015, 
reflecting both solid organic increases and the inclusion of seven months of incremental CDW UK sales. Total Net sales increased 
8.3% on a constant currency basis. There were five key trends that impacted our Net sales growth. First, customers were seeking 
to optimize their infrastructure by extending asset lives or adding capacity, which led to increases in warranties and virtualization 
software. Second, customer focus on designing IT securely continued to be a major area of interest for customers, and we saw 
excellent increases across our entire security portfolio, including security software. We also saw our customers seeking architectures 
to increase the flexibility and efficiency of their IT infrastructure, which drove increased adoption of cloud solutions for certain 
workloads, including security, as well as increased sales of hyper-converged infrastructure. Fourth, we saw the on-going trend 
where a greater proportion of solutions are being delivered via software. With software becoming more “mission critical,” customers 
continued to turn to software assurance to protect their investment. Finally, customer demand for digital signage and video screens, 
as well as notebook/mobile devices, drove growth across all of our customer end-markets.

Corporate segment Net sales in 2016 increased $11 million, or 0.2%, year over year, as customer demand for longer tail 
purchases, including data center and networking solutions, was impacted by slow economic growth and market trends. Corporate 
had strong sales performance in notebook/mobile devices and software products.

Economic conditions had less of an impact on Small Business results, as Net sales to Small Business customers increased 
by $51 million, or 4.6%, between periods, driven by growth in notebooks/mobile devices, desktops and video projection hardware.

Public segment Net sales in 2016 increased $406 million, or 7.8%, between years. Net sales to government customers 
increased $163 million, or 9.6%. State and local government customers continued to focus on public safety and we benefited from 
new contracts. Our Federal channel saw low single-digit growth as the success we had meeting new strategic programs was partially 
offset by the impact of several large client device purchase orders that were delayed into 2017. Net sales to education customers 
increased $199 million, or 11.0%, year over year, driven by continued success providing client devices to support digital testing 
and curriculums, as well as desktops and video projection hardware to support new learning environments for students. Healthcare 
growth was 2.6% or $43 million, driven by notebooks/mobile devices, desktops, and software. Patient data security continues to 
be a top concern. We continued to see some of our larger customers shifting priorities to reducing costs due to industry consolidation.

Net sales in Other, which is comprised of our Canadian and CDW UK operations, increased $526 million, or 62.8%, 
compared to 2015. The increase in Net sales was primarily driven by the impact of consolidating twelve months of CDW UK Net 
sales in 2016 compared to consolidating five months of CDW UK results in 2015. Both our Canadian and UK businesses grew 

40

 
 
 
 
 
 
 
 
Table of Contents

high-single digits in local currency in 2016. Currency was impacted by Canadian dollar to US dollar translation in the first half 
of the year and British pound to US dollar translation in the second half.

Gross profit

Gross  profit  increased $211  million,  or 10.0%,  to $2,327  million in 2016,  compared  to $2,116  million in  2015. As  a 

percentage of Net sales, Gross profit increased 30 basis points to 16.6% in 2016, from 16.3% in 2015.

Gross profit margin was positively impacted by a higher mix of net service contract revenue as customers looked to 
extend the life of equipment through warranties, protect their software investments through software assurance and adopt cloud 
solutions to deliver certain workloads. All of these solutions grew faster than our overall Net sales. In addition, vendor partner 
funding positively impacted gross margin. These increases helped offset the impact from unfavorable product margin.

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,  net  service  contract  revenue, 
commission revenue, pricing strategies, market conditions and other factors.

Selling and administrative expenses

Selling  and  administrative  expenses increased $119  million,  or 9.7%,  to $1,345  million in 2016,  compared  to  $1,226 
million in 2015.  As  a  percentage  of  total  Net  sales,  Selling  and  administrative  expenses increased 20 basis  points 
to 9.6% in 2016, up from 9.4% in 2015. Payroll costs increased $65 million, or 11.7%, year over year, primarily due to incremental 
coworker hires at the end of 2015, higher compensation costs consistent with increased Gross profit and the inclusion of twelve 
months of CDW UK payroll costs in 2016 compared to five months in 2015. Total coworker count was 8,516 at December 31, 
2016,  up 51 from 8,465 at  December 31,  2015. Amortization  expense  related  to  intangibles  increased  $18  million,  or  8.8%, 
during 2016 compared to 2015, primarily due to incremental amortization expense related to the intangible assets arising from 
our acquisition of CDW UK. Non-cash equity-based compensation expense increased $8 million, or 25.8%, during 2016 compared 
to 2015, primarily due to annual equity awards granted under our 2013 Long-Term Incentive Plan, performance against long-term 
incentive program targets and equity awards granted in connection with our acquisition of CDW UK.

Certain costs related to technology specialists have been reclassified between our Corporate, Small Business and Public 
segments. The prior period has been reclassified to conform to the current period presentation. 

Amounts have been recast to present Small Business as its own operating and reportable segment.

Effective January 1, 2016, CDW Advanced Services is included in our Corporate, Small Business and Public segments 
and Other is comprised of CDW Canada and CDW UK. The prior period has been reclassified to conform to the current 
period presentation.

Includes the financial results for our other operating segments, CDW Canada and CDW UK, which do not meet the 
reportable segment quantitative thresholds.

Includes Headquarters’ function costs that are not allocated to the segments. Certain Headquarters expenses have been 
allocated to CDW Canada in 2016. The prior period has been reclassified to conform to the current period presentation.

Income  from  operations  was $819  million in 2016,  an  increase  of $77  million,  or 10.4%,  compared  to $742 
million in 2015. Total  operating  margin increased 20 basis  points  to 5.9% in 2016,  from 5.7% in 2015.  Operating  margin  was 
positively impacted by the increase in Gross profit margin, driven by higher contribution from net service contract revenue and 
vendor partner funding. Selling and administrative expenses as a percentage of Net sales increased 20 basis points in 2016 versus 
2015, primarily reflecting increased sales compensation and coworker costs resulting from the inclusion of CDW UK expenses 
for twelve months in 2016 compared to five months in 2015.

Corporate segment income from operations was $454 million in 2016, an increase of $21 million, or 4.9%, compared 
to $433 million in 2015. Corporate segment operating margin increased 30 basis points to 7.7% in 2016, from 7.4% in 2015. This 
increase was primarily due to an increase in Gross profit driven by a higher mix of net service contract revenue, as well as higher 
volume rebates, partially offset by an increase in Selling and administrative expenses as a percentage of Net sales, due to higher 
sales payroll costs.

Small Business segment income from operations was $69 million in 2016, an increase of $1 million, or 0.9%, compared 
to 2015. Small Business operating margin decreased by 30 basis points to 6.0% in 2016, from 6.3% in 2015. The decrease in 
operating margin was primarily due to an increase in Selling and administrative expenses as a percentage of Net sales, due to 
higher sales payroll costs.

Public  segment  income  from  operations  was $368  million in 2016,  an  increase  of $39  million,  or 12.0%,  compared 
to $329 million in 2015. Public segment operating margin increased 30 basis points to 6.6% in 2016, from 6.3% in 2015. This 
decrease was driven primarily due to an increase in Net sales and Gross profit driven by a higher mix of net service contract 
revenue, as well as higher volume rebates, partially offset by an increase in Selling and administrative expenses as a percentage 
of Net sales, due to higher sales payroll costs.

Other income from operations was $44 million in 2016, an increase of $17 million, or 60.9%, compared to $27 million
in 2015. This was primarily due to the inclusion of an additional seven months of CDW UK income from operations. Other 
operating margin percentage remained flat at 3.2% in both 2016 and 2015.

Interest expense, net

At December 31,  2016,  our  outstanding  long-term  debt  totaled $3,234  million,  compared  to $3,260  million at 
December 31,  2015,  a  decrease  of  $26  million  primarily  due  to  principal  payments  on  the  loans.  Net  interest  expense 
in 2016 was $147 million, a decrease of $13 million, compared to $160 million in 2015. This decrease was primarily due to the 
lower effective interest rates and the lower principal loan balances for 2016 compared to 2015 as a result of redemptions and 
refinancing activities completed during 2016 and 2015, and the impact in 2016 of mark-to-market gains associated with our interest 
rate cap agreements.

Net loss on extinguishments of long-term debt

For  information  regarding  our  debt,  see  Note  10  (Long-Term  Debt)  to  the  accompanying  Consolidated  Financial 
Statements. During 2016, we recorded a net loss on extinguishments of long-term debt of $2 million compared to $24 million in 
2015.

We repaid all of the remaining aggregate principal amount outstanding. The loss recognized represents the difference 
between the aggregate principal amount and the net carrying amount of the purchased debt, adjusted for the remaining 
unamortized deferred financing costs and premium.

Gain on remeasurement of equity investment

On August 1, 2015, we completed the acquisition of CDW UK by purchasing the remaining 65% of its outstanding 
common stock which increased our ownership interest from 35% to 100%, and provided us control. As a result, our previously 
held 35% equity investment was remeasured to fair value, resulting in a gain of $98 million recorded in Gain on remeasurement 
of equity investment in the Consolidated Statements of Operations.

Income tax expense

Income tax expense was $248 million in 2016, compared to $244 million in 2015. The effective income tax rate, expressed 
by calculating income tax expense or benefit as a percentage of income before income taxes, was 36.9% and 37.7% for 2016
and 2015, respectively.

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 compensation as a result of 
adopting ASU 2016-09. For 2015, the effective tax rate differed from the US federal statutory rate primarily due to state income 
taxes  and  withholding  tax  expense  on  the  earnings  of  our  Canadian  business  as  a  result  of  no  longer  asserting  permanent 
reinvestment, which was partially offset by a deferred tax benefit as a result of a tax rate reduction in the UK. The lower effective 
tax rate for 2016 as compared to 2015 was primarily attributable to a larger benefit in 2016 related to our international income, 
which is taxed at lower tax rates than our US income, excess tax benefits on equity compensation as a result of adopting ASU 
2016-09 in 2016 and less Canadian withholding tax expense in 2016 than in 2015, partially offset by a greater deferred tax benefit 
related to UK tax rate reductions in 2015 than in 2016.

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, 
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. We also have $996 
million of availability for borrowings under our senior secured asset-based revolving credit facility and an additional £50 million
($68 million at December 31, 2017) 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 Activities

On March 31, 2017, we amended, extended and increased our Revolving Loan to a five-year, $1.5 billion senior secured 
asset-based revolving credit facility, with the facility being available to us for borrowings, issuance of letters of credit and floorplan 
financing. In connection with the amendment of the previous facility, we recorded a loss on extinguishment of long-term debt of 
$1 million in the Consolidated Statement of Operations during 2017, representing a write-off of a portion of unamortized deferred 
financing costs. Fees of $4 million related to the Revolving Loan were capitalized as deferred financing costs and are being 
amortized over the five-year term of the facility on a straight-line basis. These deferred financing costs are recorded in Other assets 
on the Consolidated Balance Sheets.

On March 2, 2017, the proceeds from the issuance of the 2025 Senior Notes, along with cash on hand and proceeds from 
Revolving Loan borrowings, were deposited with the trustee to redeem all of the remaining $600 million aggregate principal 
amount of the 2022 Senior Notes at a redemption price of 106.182% of the principal amount redeemed, plus accrued and unpaid 
interest through the date of redemption. The redemption date was April 2, 2017. On the same date, the indenture governing the 
2022 Senior Notes was satisfied and discharged. In connection with this redemption, we recorded a loss on extinguishment of 
long-term debt of $43 million in the Consolidated Statement of Operations for 2017. This loss represents $37 million in redemption 
premium and $6 million for the write-off of the remaining deferred financing costs related to the 2022 Senior Notes. 

On February 28, 2017, we amended the Term Loan to reprice the facility, reducing interest rate margins by 25 basis points. 
The Term Loan replaced the prior senior secured term loan facility (the “Prior Term Loan Facility”) that had an outstanding 
aggregate principal amount of $1.5 billion. We are required to pay quarterly principal installments equal to 0.25% of the original 
principal amount of the Prior Term Loan Facility, with the remaining principal amount payable on the maturity date of August 17, 
2023,  which  was  retained  from  the  Prior  Term  Loan  Facility.  In  connection  with  this  refinancing,  we  recorded  a  loss  on 
extinguishment of long-term debt of $14 million in the Consolidated Statement of Operations for the year ended December 31, 
2017. This loss represented the write-off of a portion of the unamortized deferred financing costs 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, we incurred and 
recorded $2 million in deferred financing fees, which are recorded as a reduction to the debt as of December 31, 2017.

Refer to Note 10 (Long-Term Debt) for additional information.

Share Repurchase Program

During 2017, we repurchased 9 million shares of our common stock for $534 million under the previously announced 
$750 million share repurchase program. 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 or 
through  privately  negotiated  or  other  transactions,  depending  on  share  price,  market  conditions  and  other  factors.  As  of

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.

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 compared to 2015 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.

The change in cash flows reflected stronger operating results driven by Net sales growth and the impact of consolidating 
a full year of CDW UK financial results in 2016, compared to five months in 2015.

The change in cash flows was primarily due to an increase in collections during 2016 due to the higher accounts receivable 
balance as of December 31, 2015 driven by higher sales in our Public segment where customers generally take longer to 
pay than customers in our Corporate and Small Business segments. In addition, the lower accounts receivable balances 
as of December 31, 2014, driven by early payments from certain customers, resulted in lower cash flows in the prior year 
period.

The increase in cash flows was primarily due to the timing of inventory purchases and longer payment terms with certain 
vendors.

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:

The cash conversion cycle was 19 days at December 31, 2017 and 2016. The increase in DSO was primarily driven by 
higher Net sales and related Accounts receivable for third-party services such as SaaS, software assurance and warranties. These 
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 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. In addition, DPO also increased due to the mix of payables with certain vendors that have longer payment terms.

The cash conversion cycle was 19 and 21 days at December 31, 2016 and 2015, respectively. The increase in DSO was 
primarily driven by higher Net sales and related Accounts receivable for third-party services such as SaaS, software assurance and 
warranties. These services have an unfavorable impact on DSO as the receivable is recognized on the balance sheet on a gross

to the impact of these services on DPO, DPO also increased due to the mix of payables with certain vendors that have longer 
payment terms.

Investing Activities

Net cash used in investing activities increased $15 million in 2017 compared to 2016. Capital expenditures increased 
$17 million to $81 million from $64 million for 2017 and 2016, respectively, primarily related to improvements to our information 
technology systems.

Net cash used in investing activities decreased $289 million in 2016 compared to 2015. The decrease in cash used was 
primarily due to the completion of the acquisition of CDW UK in 2015. Additionally, capital expenditures decreased $26 million 
to $64 million from $90 million for 2016 and 2015, respectively, primarily due to spending for our new office location in 2015.

Financing Activities

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 for financing activities of $228 
million and by share repurchases during 2017, which resulted in an increase in cash used for financing activities of $167 million. 
For more information on our share repurchase program, see Part II, Item 5, “Market for Registrant’s Common Equity, Related 
Stockholder Matters and Issuer Purchases of Equity Securities.” 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 

49

Table of Contents

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.

Net cash used in financing activities increased $78 million in 2016 compared to 2015. The increase was primarily driven 
by higher share repurchases during the year ended December 31, 2016, which resulted in an increase in cash used for financing 
activities of $126 million. The increase was partially offset by the changes in accounts payable-inventory financing, which resulted 
in an increase in cash provided for financing activities of $48 million. The increase in cash provided by accounts payable-inventory 
financing was primarily due to a new vendor added to our previously existing inventory financing agreement. For a description 
of the inventory financing transactions impacting each period, see Note 7 (Inventory Financing Agreements) to the accompanying 
Consolidated Financial Statements. 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.”

Long-Term Debt and Financing Arrangements

As of December 31, 2017, we had total indebtedness of $3.2 billion, of which $1.5 billion was secured indebtedness. At 
December 31, 2017, 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 $1.2 billion at December 31, 2017. The 
amount of restricted payment capacity for the CDW UK Term Loan was $98 million.

For additional details regarding our debt and refinancing activities, refer to Note 10 (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 7 (Inventory Financing Agreements) to the accompanying Consolidated Financial 
Statements.

Contractual Obligations

We have future obligations under various contracts relating to debt and interest payments, operating leases and payment 
obligations  under  the  Tax  Cuts  and  Jobs Act.  Our  estimated  future  payments,  based  on  undiscounted  amounts,  under  these 
obligations that existed as of December 31, 2017, 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 and by accelerating our overall cash conversion cycle. 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 16 (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 and liabilities and disclosure of contingent assets 
and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the 
reported periods. We base our estimates on historical experience and on various other assumptions that we believe 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. These estimates have not historically required significant management judgment. 
Our actual results have not differed materially from our estimates, nor have we historically made significant changes to the methods 
for determining these 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.

In Note 1 (Description of Business and Summary of Significant Accounting Policies) to the accompanying Consolidated 
Financial Statements, we include a discussion of the significant accounting policies used in the preparation of our Consolidated 
Financial Statements. We believe the following are the most critical accounting policies and estimates that include significant 
judgments used in the preparation of the Consolidated Financial Statements. We consider an accounting policy or estimate to be 
critical if it requires assumptions to be made that were uncertain at the time they were made, and if changes in these assumptions 
could have a material impact on our financial condition or results of operations.

Revenue Recognition

We are a primary distribution channel for a large group of vendors and suppliers, including OEMs, software publishers 
and wholesale distributors. We record revenue from sales transactions when title and risk of loss are passed to our customer, there 
is persuasive evidence of an arrangement for sale, delivery has occurred and/or services have been rendered, the sales price is 
fixed or determinable, and collectability is reasonably assured. Our shipping terms typically specify F.O.B. destination, at which 
time title and risk of loss have passed to the customer. 

Revenues from the sales of hardware products and software products and licenses are generally recognized on a gross 
basis with the selling price to the customer recorded as sales and the acquisition cost of the product recorded as cost of sales. These 
items can be delivered to customers in a variety of ways, including (i) as physical product shipped from our warehouse, (ii) via 
drop-shipment by the vendor or supplier, or (iii) via electronic delivery for software licenses. At the time of sale, we record an 
estimate for sales returns and allowances based on historical experience. Our vendor partners warrant most of the products we 
sell. 

We leverage drop-shipment arrangements with many of our vendors and suppliers to deliver products to our customers 
without having to physically hold the inventory at our warehouses, thereby increasing efficiency and reducing costs. We recognize 
revenue for drop-shipment arrangements on a gross basis upon delivery to the customer with contract terms that typically specify 
F.O.B. destination. We recognize revenue on a gross basis as the principal in the transaction because we are the primary obligor 
in the arrangement, we assume inventory risk if the product is returned by the customer, we set the price of the product charged 
to the customer, we assume credit risk for the amounts invoiced, and we work closely with our customers to determine their 

51

Table of Contents

hardware and software specifications. These arrangements represent approximately 50% of total Net sales, of which approximately 
25% relate to electronic delivery for software licenses. 

Revenue from professional services is recognized in either of two ways: services as an hourly rate (recognized using a 
percentage of completion model) or a fixed fee (recognized using a proportional performance model for the fixed fee). Revenues 
for cloud computing solutions including SaaS and IaaS arrangements with one time invoicing to the customer are recognized at 
the time of invoice. Revenues for data center services such as managed and remote managed services, server co-location, internet 
connectivity, data backup and storage, and SaaS and IaaS arrangements where the customer is invoiced over time are recognized 
over the period service is provided.

We also sell certain products for which we act as an agent. Products in this category include the sale of third-party services, 
warranties, software assurance (“SA”) and third-party hosted SaaS and IaaS arrangements. SA is a product that allows customers 
to upgrade, at no additional cost, to the latest technology if new applications are introduced during the period that the SA is in 
effect. These sales do not meet the criteria for gross sales recognition, and thus are recognized on a net basis at the time of sale. 
Under Net sales recognition, the cost paid to the vendor or third-party service provider is recorded as a reduction to sales, resulting 
in Net sales being equal to the Gross profit on the transaction. 

Our larger customers are offered the opportunity by certain of our vendors to purchase software licenses and SA under 
enterprise agreements (“EAs”). Under EAs, customers are considered to be compliant with applicable license requirements for 
the ensuing year, regardless of changes to their employee base. Customers are charged an annual true-up fee for changes in the 
number of users over the year. With most EAs, our vendors will transfer the license and bill the customer directly, paying resellers 
such as us an agency fee or commission on these sales. We record these fees as a component of Net sales as earned and there is 
no corresponding cost of sales amount. In certain instances, we bill the customer directly under an EA and account for the individual 
items sold based on the nature of the item. Our vendors typically dictate how the EA will be sold to the customer. 

We also sell some of our products and services as part of bundled contract arrangements containing multiple deliverables, 
which may include a combination of the products and services. For each deliverable that represents a separate unit of accounting, 
total arrangement consideration is allocated based upon the relative selling prices of each element. The allocated arrangement 
consideration is recognized as revenue in accordance with the principles described above. Selling prices are determined by using 
vendor specific objective evidence (“VSOE”) if it exists. Otherwise, selling prices are determined using third party evidence 
(“TPE”). If neither VSOE or TPE is available, we use our best estimate of selling prices.

We record freight billed to our customers as Net sales and the related freight costs as a Cost of sales.

Deferred revenue includes (1) payments received from customers in advance of providing the product or performing 

services, and (2) amounts deferred if other conditions of revenue recognition have not been met. 

We perform an analysis of the estimated number of days of sales in-transit to customers at the end of each period based 
on a weighted-average analysis of commercial delivery terms that includes drop-shipment arrangements. This analysis is the basis 
upon which we estimate the amount of sales in-transit at the end of the period and adjust revenue and the related costs to reflect 
only what has been received by the customer. Changes in delivery patterns may result in a different number of business days used 
in making this adjustment and could have a material impact on our revenue recognition for the period.

Vendor Programs

We receive incentives from certain of our vendors related to cooperative advertising allowances, 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 inventory, depending on the nature of the incentive. 
Vendors may change the terms of some or all of these programs, which could have an impact on our results of operations.

We record receivables from vendors 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. If actual performance does not match our estimates, 
we may be required to adjust our receivables. We record reserves for vendor receivables for estimated losses due to vendors’ 
inability to pay or rejections by vendors of claims; however, if actual collections differ from our estimates, we may incur additional 
losses that could have a material impact on Gross profit and Income from operations.

Goodwill 

Goodwill is not amortized but is subject to periodic testing for impairment at the reporting unit level. We perform an 
evaluation of goodwill, utilizing either a quantitative or qualitative impairment test. A qualitative assessment is performed on at 
least 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 
52

Table of Contents

value. We perform 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. Our reporting units used to assess 
potential goodwill impairment are the same as our operating segments.

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 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 our fair value in an orderly transaction between market participants.

Under the income approach, we determine 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. We use a range of 2.0-3.5% long-
term assumed consolidated annual Net sales growth rate for periods after the terminal year.

Under the market approach, we utilize 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 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.

Under a qualitative assessment, the most recent quantitative assessment is the starting point to determine if it is more 
likely than not that the reporting unit’s fair value is less than its carrying value. As part of this qualitative assessment, we assess 
relevant events and circumstances including macroeconomic conditions, industry and market conditions, cost factors, overall 
financial performance, changes in share price and entity-specific events.

2017 Impairment Analysis

We  completed  our  annual  impairment  analysis  as  of  December 1,  2017.  For  the  Corporate,  Small  Business  and  UK 
reporting units, we performed a qualitative analysis. We determined that it was more-likely-than-not that the individual fair values 
of the Corporate, Small Business and UK reporting units exceeded the individual carrying values and therefore a quantitative 
impairment analysis was deemed unnecessary. Although uncertainty regarding the impact of Brexit still exists in the current year, 
we do not believe there to be any additional risk that would indicate the quantitative analysis performed in the prior year to have 
different results.  Therefore a qualitative analysis was deemed appropriate for the UK reporting unit. We performed a quantitative 
analysis of the Public and Canada reporting units. Based on the results of the quantitative analysis, we 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. We identified that the most sensitive assumptions used in the quantitative analysis were Net sales growth and EBITDA 
margin and, although we believe our assumptions are reasonable based on current market conditions, actual results may vary 
significantly and could expose us to impairment charges in the future.

With the establishment of Small Business as its own reporting unit, we performed a quantitative analysis in order to 
allocate Goodwill between Corporate and Small Business. Based on the results of the quantitative analysis performed as of January 
1, 2017, we determined that the fair values of Corporate and Small Business reporting units exceeded their carrying values by 
227% and 308%, respectively, and no impairment existed.

2016 Impairment Analysis

We completed our annual impairment analysis as of December 1, 2016. For the Corporate (which, as of December 1, 
2016, included Small Business), Public and Canada reporting units, we performed a qualitative analysis. We determined that it 
was more-likely-than-not that the individual fair values of the Corporate, Public and Canada reporting units exceeded the individual 
carrying values and therefore a quantitative impairment analysis was deemed unnecessary. Due to the substantial uncertainty 
regarding the impact of Brexit, we performed a quantitative analysis of the CDW UK reporting unit. Based on the results of the 
quantitative analysis, we determined that the fair value of the CDW UK reporting unit exceeded its carrying value by 16% and 
no impairment existed. We identified that the most sensitive assumptions used in the quantitative analysis were Net sales growth 
and EBITDA margin and, although we believe our assumptions are reasonable based on current market conditions, actual results 
may vary significantly and could expose us to impairment charges in the future.

Intangible assets

Intangible  assets  include  customer  relationships,  trade  names,  internally  developed  software  and  other  intangibles. 
Intangible assets with finite lives are amortized on a straight-line basis over the estimated useful lives of the assets. The cost of 
software developed or obtained for internal use is capitalized and amortized on a straight-line basis over the estimated useful life. 
These intangible assets are reviewed for impairment whenever 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, we evaluate whether events and circumstances warrant a revision to the remaining estimated useful life of each of 
these intangible assets. If we 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.

During the years ended December 31, 2017 and 2016, we concluded our intangible assets with finite lives were not 

impaired and no changes to the remaining useful lives were necessary.

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. We perform an evaluation of the realizability of our deferred tax assets on a quarterly basis. This evaluation 
requires us to use estimates and make 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 we operate, and prudent and feasible 
tax planning strategies.

We account for unrecognized tax benefits based upon our assessment of whether a tax benefit is more likely than not to 
be sustained upon examination by tax authorities. We report a liability for unrecognized tax benefits resulting from unrecognized 
tax benefits taken or expected to be taken in a tax return and recognize interest and penalties, if any, related to 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. As we continue to evaluate our accounting policy with 
respect to GILTI, the provisional estimates were reported on the basis that GILTI will be accounted for as a period cost when 
incurred. Accordingly, we are not providing deferred taxes for basis differences expected to reverse as GILTI.

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, 2017, we have interest rate cap agreements in effect through December 31, 2018 with a combined 
notional amount of $1.4 billion which entitle us to payments from the counterparty of the amount, if any, by which three-month 
LIBOR exceeds 1.5% during the agreement period.

For additional details, see Note 10 (Long-Term Debt) 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 Canadian dollar and the British pound, 
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 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, 2017 and 2016, 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, 2017, and the related notes and the 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 at December 
31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 
31, 2017, in conformity with U.S. 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, 2017, 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 28, 2018 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 U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
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 included 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.

CDW CORPORATION AND SUBSIDIARIES

1. 

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 19 (Supplemental Guarantor Information)
and does not hold any material assets or engage in any business activities or operations.

In August 2015, the Company completed the acquisition of Kelway TopCo Limited (“Kelway”), a UK-based IT solutions 
provider with global offerings by purchasing the remaining 65% of its outstanding common stock, which increased the 
Company’s ownership interest from 35% to 100% and provided the Company control. In 2016 Kelway was rebranded 
CDW UK. 

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”).

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.

CDW CORPORATION AND SUBSIDIARIES

Accounts Receivable

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 initial 
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

Estimated
Useful Lives

5 to 10 years

5 to 25 years

3 to 5 years

3 to 5 years

5 to 10 years

The Company has asset retirement obligations associated with commitments to return property subject to the terms of 
operating leases to its original condition upon lease termination. At December 31, 2017 and 2016, the Company’s asset 
retirement liability was less than $2 million and $1 million, respectively.

Equity Investments

If the Company is not required to consolidate its investment in another entity because it does not have control, the Company 
uses the equity method if it (i) can exercise significant influence over the other entity and (ii) holds common stock of the 
other entity. Under the equity method, investments are carried at cost, plus or minus the Company’s share of equity in 
the increases and decreases in the investee’s net assets after the date of acquisition and adjustments for basis differences. 
The Company’s share of the income or loss of equity method investees is included in Other income (expense), net in the 
Consolidated Statements of Operations.

Goodwill

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 

64

Table of Contents

CDW CORPORATION AND SUBSIDIARIES

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 
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. The Company uses a range of 2.0-3.5% long-term assumed consolidated annual Net sales growth rate for periods 
after the terminal year.

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:

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.  The gain or loss on the derivative instruments is 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.

The Company is a primary distribution channel for a large group of vendors and suppliers, including original equipment 
manufacturers (“OEMs”), software publishers, wholesale distributors and cloud providers. The Company records revenue 
from sales transactions when title and risk of loss are passed to the customer, there is persuasive evidence of an arrangement 
for sale, delivery has occurred and/or services have been rendered, the sales price is fixed or determinable, and collectability 
is reasonably assured. The Company’s shipping terms typically specify F.O.B. destination, at which time title and risk 
of loss have passed to the customer.

Revenues from the sales of hardware products and software licenses are generally recognized on a gross basis with the 
selling price to the customer recorded as sales and the acquisition cost of the product recorded as cost of sales. These 
items 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 for software licenses. At the 
time  of  sale,  the  Company  records  an  estimate  for  sales  returns  and  allowances  based  on  historical  experience. The 
Company’s vendor partners warrant most of the products the Company sells.

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, thereby increasing efficiency and reducing 

66

Table of Contents

CDW CORPORATION AND SUBSIDIARIES

costs. The Company recognizes revenue for drop-shipment arrangements on a gross basis upon delivery to the customer 
with contract terms that typically specify F.O.B. destination.

Revenue from professional services is either recognized as provided for services billed at an hourly rate, recognized using 
a percentage of completion model for fixed fee project work or recognized using a proportional performance model for 
services provided at a fixed fee. Revenues for cloud computing solutions including Software as a Service (“SaaS”) and 
Infrastructure as a Service (“IaaS”) arrangements with one time invoicing to the customer are recognized at the time of 
invoice. Revenues for data center services such as managed and remote managed services, server co-location, internet 
connectivity, data backup and storage, and SaaS and IaaS arrangements where the customer is invoiced over time are 
recognized over the period service is provided.

The Company also sells certain products for which it acts as an agent. Products in this category include the sale of third-
party services, warranties, software assurance (“SA”) and third-party hosted SaaS and IaaS arrangements. SA is a product 
that allows customers to upgrade, at no additional cost, to the latest technology if new applications are introduced during 
the period that the SA is in effect. These sales do not meet the criteria for gross sales recognition, and thus are recognized 
on a net basis at the time of sale. Under Net sales recognition, the cost paid to the vendor or third-party service provider 
is recorded as a reduction to sales, resulting in Net sales being equal to the gross profit on the transaction.

The Company’s larger customers are offered the opportunity by certain of its vendors to purchase software licenses and 
SA under enterprise agreements (“EAs”). Under EAs, customers are considered to be compliant with applicable license 
requirements for the ensuing year, regardless of changes to their employee base. Customers are charged an annual true-
up fee for changes in the number of users over the year. With most EAs, the Company’s vendors will transfer the license 
and bill the customer directly, paying resellers such as the Company 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. 
In certain instances, the Company bills the customer directly under an EA and accounts for the individual items sold 
based on the nature of the item. The Company’s vendors typically dictate how the EA will be sold to the customer.

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 separate 
unit of accounting, total arrangement consideration is allocated based upon the relative selling prices of each element. 
The allocated arrangement consideration is recognized as revenue in accordance with the principles described above. 
Relative selling prices are determined by using vendor specific objective evidence (“VSOE”) if it exists. Otherwise, 
selling prices are determined using third-party evidence (“TPE”). If neither VSOE or TPE is available, the Company uses 
its best estimate of selling prices.

The Company records freight billed to its customers as Net sales and the related freight costs as a Cost of sales.

Deferred revenue includes (i) payments received from customers in advance of providing the product or performing 
services and (ii) amounts deferred if other conditions of revenue recognition have not been met.

The Company performs an analysis of the estimated number of days of sales in-transit to customers at the end of each 
period based on a weighted-average analysis of commercial delivery terms that includes drop-shipment arrangements. 
This analysis is the basis upon which the Company estimates the amount of sales in-transit at the end of the period and 
adjusts revenue and the related costs to reflect only what has been received by the customer. Changes in delivery patterns 
may result in a different number of business days used in making this adjustment and could have a material impact on 
the Company’s revenue recognition for the period.

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.  Estimated 
forfeiture rates 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. As the Company continues to evaluate 
its accounting policy with respect to GILTI, the provisional estimates were reported on the basis that GILTI will be 
accounted  for  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. This ASU is effective for the 
Company beginning the first quarter of 2019 and allows for early adoption. The Company is currently evaluating the 
impact the ASU will have on its Consolidated Financial Statements.

Accounting for Goodwill Impairment

In  January  2017,  the  FASB  issued ASU  2017-04,  Simplifying  the  Test  for  Goodwill  Impairment  (Topic  350).  The 
amendments in this update eliminate step two of the current two-step process, which requires a hypothetical purchase 
price allocation when an impairment is determined to have occurred. This ASU 2017-04 is effective for the Company 
beginning in the first quarter of 2020 and allows for early adoption. The Company elected to early adopt this standard 
during the third quarter of 2017. The Company will continue to perform the quantitative goodwill impairment evaluation 

68

Table of Contents

CDW CORPORATION AND SUBSIDIARIES

by comparing the fair value of each reporting unit to its carrying amount. Under the new standard, if the Company is 
required to recognize an impairment charge, the amount of the charge will be measured as the excess of a reporting unit's 
carrying amount over its fair value, not to exceed the carrying amount of goodwill. The adoption of this ASU did not 
have an impact on the Company's Consolidated Financial Statements. 

Classification of Certain Cash Receipts and Cash Payments

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230), 
providing guidance for eight specific cash flow issues with the objective of reducing the existing diversity in practice.  
Among the updates, this standard requires cash payments for debt extinguishment costs to be classified as cash outflows 
from financing activities, which is consistent with the Company's current practice. This ASU is effective for the Company 
beginning in the first quarter of 2018 and allows for early adoption. The Company elected to early adopt this standard 
during  the  third quarter  of  2017. 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), requiring 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. Although  the  Company  is  currently  evaluating  the  provisions  of  the ASU  to 
determine how it will be affected, the primary impact to the Company of the new ASU will be to record assets and 
liabilities for current operating leases, which are principally related to the Company’s real estate portfolio.

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which, along with 
amendments issued in 2015 and 2016, will replace most existing revenue recognition guidance under GAAP and eliminate 
industry-specific guidance. The core principle of the new guidance is that an entity should recognize revenue for the 
transfer of goods and services equal to an amount it expects to be entitled to receive for those goods and services. The 
ASU, as amended, will be effective for the Company beginning in the first quarter of 2018. The new guidance permits 
two  methods  of  adoption:  retrospectively  to  each  prior  reporting  period  presented  (full  retrospective  method),  or 
retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application 
(the cumulative catch-up transition method). 

The Company established a cross-functional implementation team to analyze the effect of the ASU. The Company utilized 
a bottom-up approach to analyze the impact of the standard on its contract portfolio by reviewing the current accounting 
policies and practices to identify potential differences that would result from applying the requirements of the new standard 
to its revenue contracts. In addition, the Company identified, and is in the process of implementing, appropriate changes 
to  its  business  processes,  systems  and  controls  to  support  recognition  and  disclosure  under  the  new  standard.  The 
implementation team reports its findings and progress of the project to management and the Audit Committee on a frequent 
basis. 

The Company adopted the guidance on January 1, 2018, and utilized the full retrospective method. 

The Company has finalized its accounting policies under the new standard and it has determined: 

• 

The accounting for bill and hold transactions will result in revenue for certain of those arrangements being 
recognized earlier than under current GAAP. This change will not materially impact Net sales or Net income;

69

Table of Contents

CDW CORPORATION AND SUBSIDIARIES

• 

• 

In certain security software transactions when accompanying third-party delivered software assurance is deemed 
to be critical or essential to the core functionality of the software license, the Company has determined that the 
software  license  and  the  accompanying  third-party  delivered  software  assurance  are  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 will recognize them on a net basis. The 
Company currently recognizes revenue from the software license on a gross basis (i.e., acting as a principal) 
and accompanying third-party delivered software assurance on a net basis. This change will reduce both Net 
sales and Cost of sales with no impact on reported Gross profit.

The  accounting  for  revenue  related  to  hardware,  software  (excluding  the  above)  and  services  will  remain 
substantially unchanged.

The adoption of the ASU is expected to impact the Company’s results as follows:

Acquisition

On August 1,  2015,  the  Company  completed  the  acquisition  of  CDW  UK  by  purchasing  the  remaining  65%  of  its 
outstanding common stock which increased the Company’s ownership interest from 35% to 100%, and provided the 
Company control.

The Company issued 2 million shares of CDW common stock. The fair value of the common stock was based 
on the closing market price on July 31, 2015, adjusted for the lack of marketability as the shares of CDW common 
stock issued to certain sellers are subject to a three-year lock up restriction from August 1, 2015. One of the 
sellers granted 1 million stock options to certain CDW UK coworkers over his shares of CDW common stock 
received in the transaction. The fair value of these stock options was $22 million, which has been accounted for 
as  post-combination  stock-based  compensation  and  is  being  amortized  over  the  weighted-average  requisite 
service period of 3.2 years and recorded in Selling and administrative expenses in the Consolidated Statements 
of Operations.

As  a  result  of  the  Company  obtaining  control  over  CDW  UK,  the  Company’s  previously  held  35%  equity 
investment was remeasured to fair value, resulting in a gain of $98 million included in Gain on remeasurement 
of equity investment in the Consolidated Statements of Operations. The fair value of the previously held equity 
investment  was  determined  by  management  with  the  assistance  of  a  third  party  valuation  firm,  based  on 
information available at the acquisition date.

The unaudited pro forma Consolidated Statements of Operations in the table below summarizes the combined results of 
operations of the Company and CDW UK, as if the acquisition had been completed on January 1, 2015, and gives effect 
to pro forma events that are factually supportable and directly attributable to the transaction. The unaudited pro forma 
results reflect adjustments for equity-based compensation, acquisition and integration costs, incremental intangible asset 
amortization  based  on  the  fair  values  of  each  identifiable  intangible  asset,  which  are  subject  to  change  within  the 
measurement period, pre-acquisition equity earnings, the gain on the remeasurement of the Company’s previously held 
35% equity method investment, elimination of pre-acquisition intercompany sales transactions and the impacts of certain 
other pre-acquisition transactions. Pro forma adjustments were tax-effected at the statutory rates within the applicable 
jurisdictions. 

This unaudited pro forma information is presented for informational purposes only and may not be indicative of the 
historical results of operations that would have been obtained if the acquisition had taken place on January 1, 2015, nor 
the results that may be obtained in the future. This unaudited pro forma information does not reflect future synergies,

Goodwill is net of accumulated impairment losses of $1,571 million, $354 million and $28 million related to 
the Corporate, Public and Other segments, respectively.  

Amounts have been recast to present Small Business as its own operating and reportable segment.

Effective January 1, 2016, the CDW Advanced Services business is included in the Company's Corporate and 
Public segments.

(4) 

Other is comprised of Canada and CDW UK operating segments.

With the establishment of Small Business as its own reporting unit, the Company performed a quantitative analysis in 
order  to  allocate  Goodwill  between  Corporate  and  Small  Business.  Based  on  the  results  of  the  quantitative  analysis 
performed as of January 1, 2017, the Company determined that the fair values of Corporate and Small Business reporting 
units exceeded their carrying values by 227% and 308%, respectively, and no impairment existed.

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. Although uncertainty regarding 
the impact of the Referendum on the UK’s Membership of the European Union (“EU”), advising for the exit of the UK 
from the EU (referred to as “Brexit”) still exists in the current year, the Company does not believe there to be any additional 
risk that would indicate the quantitative analysis performed in the prior year would have a different result.  Therefore, a 
qualitative analysis was deemed appropriate for the UK reporting unit. 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.

December 1, 2016 Impairment Analysis

The Company completed its annual impairment analysis as of December 1, 2016. For the Corporate (which, as of December 
1, 2016, included Small Business), Public and Canada 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, Public and 
Canada  reporting  units  exceeded  the  respective  carrying  values. As  a  result  of  this  determination,  the  quantitative 
impairment analysis was deemed unnecessary. Due to the substantial uncertainty regarding the impact of Brexit, the 
Company performed a quantitative analysis of the CDW UK reporting unit. Based on the results of the quantitative 
analysis, the Company determined that the fair value of the CDW UK reporting unit exceeded its carrying value and no 
impairment existed.

The Senior Secured Asset-Based Revolving Credit Facility (“Revolving Loan”) includes an inventory floorplan 
sub-facility that enables the Company to maintain an inventory financing agreement with a financial intermediary 
to facilitate the purchase of inventory from certain vendors on more favorable terms than offered directly by the 
vendors.

The Company also maintains other inventory financing agreements with financial intermediaries to facilitate 
the purchase of inventory from certain vendors. As of December 31, 2017 and 2016, amounts collateralized by 
the inventory purchased under these financing agreements and a second lien on the related accounts receivable 
were $1 million and $3 million, respectively.

Financial Instruments

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 1.5% during the agreement period. The interest rate cap agreements are in effect 
from January 17, 2017 through December 31, 2018 with a combined notional amount of $1.4 billion. As of December 31, 
2017 and 2016, the interest rate cap agreements had a fair value of $5 million and 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. 

75

Table of Contents

CDW CORPORATION AND SUBSIDIARIES

The counterparty credit spreads are based on publicly available credit information obtained from a third party credit data 
provider. For additional details, see Note 10 (Long-Term Debt).

During the first quarter of 2017, the Company designated the interest rate cap agreements as cash flow hedges. The 
effective portion of changes in the fair value of derivatives that qualify as cash flow hedges is recorded in Accumulated 
other comprehensive loss and is subsequently reclassified into Interest expense in the period when the hedged forecasted 
transaction affects earnings. If a derivative is deemed to be ineffective, the ineffective portion of the change in fair value 
of the derivative is recognized directly into earnings. The Company's interest rate cap agreements were deemed effective 
during 2017, and the Company expects the derivatives will continue to be effective for the next twelve months. The 
Company recorded an insignificant gain, net of tax expense, for the effective portion of the interest rate cap agreements into 
Accumulated other comprehensive loss for the year ended December 31, 2017. During 2017, the Company reclassified 
an insignificant amount from Accumulated other comprehensive loss into Interest expense. The Company expects to 
reclassify $5 million from Accumulated other comprehensive loss into Interest expense during the next twelve months.   

Prior to the election of hedge accounting treatment, the Company recognized less than $1 million and $3 million of 
Interest income during 2017 and 2016, respectively, in the Company's Consolidated Statement of Operations related to 
the changes in the fair value of the interest rate cap agreements.

Senior Secured Asset-Based Revolving Credit Facility (“Revolving Loan”)

As of December 31, 2017, the Company had no outstanding borrowings under the Revolving Loan, less than $1 million
of undrawn letters of credit, $454 million reserved for the floorplan sub-facility and a borrowing base of $1.6 billion, 
which is based on the amount of eligible inventory and accounts receivable balances as of November 30, 2017. Borrowings 
under the Revolving Loan are limited by the borrowing base. As of December 31, 2017, the Company could have borrowed 
up to an additional $996 million under the Revolving Loan. Borrowings are also limited by a minimum liquidity condition, 
which provides that, if excess cash availability is less than the lower of (i) $125 million and (ii) the greater of (a) 10.0%
of the borrowing base, and (b) $100 million, the lenders are not required to lend additional amounts under the Revolving 
Loan unless the consolidated fixed charge coverage ratio, as defined, is at least 1.00 to 1.00.

Borrowings under the Revolving Loan bear interest at a variable interest rate plus an applicable margin. The interest rate 
margin is based on one of two indices, either (i) LIBOR or (ii) the Alternate Base Rate (“ABR”), with the ABR being the 
greater of (a) the prime rate, (b) the federal funds effective rate plus 50 basis points or (c) the one-month LIBOR plus 1.00%. 
The  applicable  margin  varies  (1.25% to 1.75% for  LIBOR  borrowings  and  0.25% to 0.75% for  ABR  borrowings) 
depending upon average daily excess cash availability under the agreement evidencing the Revolving Loan.

On March 31, 2017, the Company amended, extended and increased its Revolving Loan to a five-year, $1.5 billion senior 
secured asset-based revolving credit facility, with the facility being available to the Company for borrowings, issuance 
of letters of credit and floorplan financing. The Revolving Loan matures on March 31, 2022. The Revolving Loan replaces 
the Company’s previous revolving loan credit facility that was to mature on June 6, 2019. The Revolving Loan (i) increases 
the overall revolving credit facility capacity available to the Company from $1.3 billion to $1.5 billion, (ii) maintains the 
maximum aggregate amount of increases that may be made to the revolving credit facility of  $300 million, (iii) maintains 
the fees on the unused portion of the revolving credit facility at 25 basis points, (iv) makes permanent the 25 basis point 
reduction in the applicable interest rate margin that was previously conditioned on meeting certain credit ratings levels, 
and (v) maintains the existing inventory floorplan sub-facility. In connection with the amendment of the previous facility, 
the  Company  recorded  a  loss  on  extinguishment  of  long-term  debt  of  $1  million in  the  Consolidated  Statement  of 
Operations for the year ended December 31, 2017, representing a write-off of a portion of unamortized deferred financing 
costs. Fees of $4 million related to the Revolving Loan were capitalized as deferred financing costs and are being amortized 
over the five-year term of the facility on a straight-line basis. These deferred financing costs are recorded in Other assets 
on the Consolidated Balance Sheets.

Senior Secured Term Loan Facility (“Term Loan”)

On December 31, 2017, the outstanding principal amount of the Term Loan was $1.5 billion, excluding $2 million of 
deferred financing costs.  On February 28, 2017, the Company amended the Term Loan to reprice the facility, reducing 
interest rate margins by 25 basis points. Borrowings under the Term Loan bear interest at either (i) the ABR plus a margin 
or (ii) LIBOR plus a margin, payable quarterly on the last day of each March, June, September and December. The margin 

77

Table of Contents

CDW CORPORATION AND SUBSIDIARIES

is  based  upon  a  net  leverage  ratio  as  defined  in  the  agreement  governing  the Term  Loan,  which  is  1.00%  for ABR 
borrowings and 2.00% for LIBOR borrowings as of December 31, 2017. 

The Term Loan was issued at par. The Term Loan replaced the prior senior secured term loan facility (the “Prior Term 
Loan Facility”) that had an outstanding aggregate principal amount of $1.5 billion. The Company is required to pay 
quarterly principal installments equal to 0.25% of the original principal amount of the Prior Term Loan Facility, with the 
remaining principal amount payable on the maturity date of August 17, 2023, which was retained from the Prior Term 
Loan Facility. In connection with this refinancing, the Company recorded a loss on extinguishment of long-term debt of 
$14 million in the Consolidated Statement of Operations for the year ended December 31, 2017. This loss represented 
the write-off of a portion of the unamortized deferred financing costs 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, which are recorded as a reduction to the debt and presented in the above 
table as of December 31, 2017.

CDW UK Term Loan

On August 1, 2016, the Company entered into a new five-year £56 million ($76 million at December 31, 2017) aggregate 
principal amount term loan facility (“CDW UK Term Loan”), which replaced the prior senior secured term loan facility 
(the “Prior CDW UK Term Loan Facility”) that had an outstanding principal amount of £56 million. Fees of $1 million
were capitalized as deferred financing costs and are being amortized over the term of the loan on a straight-line basis.

Commencing  during  the  quarter  ending  September  30,  2018,  the  Company  is  required  to  make  annual  principal 
installments of £5 million ($7 million at December 31, 2017), with the remaining principal amount payable on the maturity 
date of August 1, 2021. Borrowings under the CDW UK Term Loan bear interest at LIBOR plus a margin, payable 
quarterly on the last day of each March, June, September and December. As of December 31, 2017, an interest rate 
of 1.92% was in effect, which represents LIBOR plus a 1.40% margin.

In connection with this refinancing, the Prior CDW UK Term Loan Facility was amended to include both the CDW UK 
Term Loan and a £50 million ($68 million at December 31, 2017) revolving credit facility (the “CDW UK Revolving 
Credit  Facility”). As  of  December 31,  2017,  the  Company  had  no  borrowings  from  the  CDW  UK  Revolving  Credit 
Facility.

6.0% Senior Notes due 2022 (“2022 Senior Notes”)

On March 2, 2017, the proceeds from the issuance of the 2025 Senior Notes, discussed below, along with cash on hand 
and proceeds from Revolving Loan borrowings, were deposited with the trustee to redeem all of the remaining $600 
million aggregate principal amount of the 2022 Senior Notes at a redemption price of 106.182% of the principal amount 
redeemed, plus accrued and unpaid interest through the date of redemption. The redemption date was April 2, 2017. On 
the same date, the indenture governing the 2022 Senior Notes was satisfied and discharged. 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 costs related to the 2022 Senior Notes.  

5.0% Senior Notes due 2023 (“2023 Senior Notes”)

At December 31, 2017, the outstanding principal amount of the 2023 Senior Notes was $525 million. The 2023 Notes 
will mature on September 1, 2023 and bear interest rate of 5.0% per annum, payable semi-annually on March 1 and 
September 1 of each year.

5.5% Senior Notes due 2024 (“2024 Senior Notes”)

At December 31, 2017, the outstanding principal amount of the 2024 Senior Notes was $575 million. The 2024 Senior 
Notes will mature on December 1, 2024 and bear interest at a rate of 5.5% per annum, payable semi-annually on June 1 
and December 1 of each year.

5.0% Senior Notes due 2025 (“2025 Senior Notes”)

On March 2, 2017, the Company completed the issuance of $600 million aggregate principal amount of 2025 Senior 
Notes at par. In connection with the issuance of the 2025 Senior Notes, the Company incurred and recorded $7 million
in deferred financing fees, which is recorded as a reduction to the debt and presented in the above table as of December 31, 
2017.

Table of Contents

CDW CORPORATION AND SUBSIDIARIES

At December 31, 2017, the outstanding principal amount of the 2025 Senior Notes was $600 million. The 2025 Senior 
Notes will mature on September 1, 2025 and bear interest at a rate of 5.0% per annum, payable semi-annually on March 
1 and September 1 of each year.

Debt Guarantors, Covenants and Restrictions

CDW LLC is the borrower under the Term Loan and Revolving Loan.  CDW LLC and CDW Finance Corporation are 
the co-issuers of the 2023, 2024 and 2025 Senior Notes (“Senior Notes”).  The obligations under the Term Loan, the 
Revolving Loan and the Senior Notes are guaranteed by Parent and each of CDW LLC's direct and indirect, wholly 
owned, US subsidiaries (the “Guarantors”).

The Revolving Loan is collateralized by a first priority interest in inventory (excluding inventory collateralized under 
the inventory floorplan arrangements as described in Note 7 (Inventory Financing Agreements)), deposits, and accounts 
receivable, and a second priority interest in substantially all US assets.

The  Term  Loan  is  collateralized  by  a  second  priority  interest  in  substantially  all  inventory  (excluding  inventory 
collateralized under the inventory floorplan arrangements as described in Note 7 (Inventory Financing Agreements)), 
deposits, and accounts receivable, and by a first priority interest in substantially all other U.S. assets.

As of December 31, 2017, the Company remained in compliance with the covenants under its various credit agreements. 
The Term Loan contains negative covenants that, among other things, place restrictions and limitations on the ability of 
the Guarantors to dispose of assets, incur additional indebtedness, incur guarantee obligations, prepay other indebtedness, 
make distributions or other restricted payments, create liens, make equity or debt investments, make acquisitions, engage 
in mergers or consolidations or engage in certain transactions with affiliates. As of December 31, 2017, the amount of 
CDW’s restricted payment capacity under the Term Loan was $1.2 billion. However, the Company is separately permitted 
to make restricted payments, so long as the total net leverage ratio is less than 3.25:1.00 on a pro forma basis. The total 
net leverage ratio was 2.62:1.00 as of December 31, 2017.

Each of the Senior Notes indentures contain negative covenants that, among other things, place restrictions and limitations 
on the ability of the Guarantors to enter into sale and lease-back transactions, incur additional secured indebtedness and 
create liens. The indenture governing each of the Senior Notes do not contain any financial covenants.

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 
things, the maintenance of a minimum net leverage ratio. As of December 31, 2017, the amount of restricted payment 
capacity under the CDW UK Term Loan was £73 million ($98 million at December 31, 2017).

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  the  Company’s  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. US GAAP requires 
the income tax effects of the Tax Cuts and Jobs Act to be accounted for in the period of enactment.   

As of December 31, 2017, the Company has not completed its accounting for the income tax effects of the Tax Cuts and 
Jobs Act; however, it has recorded provisional amounts for the impact of revaluing the deferred tax assets and liabilities, 
the deemed mandatory repatriation tax on the Company’s international operations’ unremitted earnings which have not 
been subject to US tax and the state income tax effects related to the change in federal tax law. 

The Company recorded an income tax benefit of $96 million to reflect the impact of revaluing US deferred tax assets 
and liabilities to 21%, which is the rate the Company expects the deferred tax assets and liabilities to reverse. The Company 
has recorded additional federal income tax expense of $20 million to reflect the deemed mandatory repatriation tax on 
the Company’s international operations’ unremitted earnings which have not been subject to US tax. The mandatory 
repatriation tax generated excess foreign tax credits of approximately $14 million, which are available for carryforward. 
The Company does not expect to utilize the foreign tax credits carryforwards prior to their expiration and it has recorded 
a $14 million valuation allowance against the foreign tax carryforwards.  The Company has recorded additional tax 
expense of less than $1 million for the state income tax impact of the Tax Cuts and Jobs Act. 

As the Company completes its analysis and refines its calculations of the federal and state income tax impact of the Tax 
Cuts and Jobs Act, it may need to adjust the measurement of the deferred tax assets and liabilities, update the historical 
earnings of its UK and Canadian operations which will impact the mandatory repatriation tax, foreign tax credit utilization, 
carryforwards and valuation allowance, and adjust the state income tax expense.

The Company has state and international income tax net operating losses of $29 million, which will expire at various 
dates from 2025 through 2032 and state and international tax credit carryforwards of $28 million, which expire at various 
dates from 2019 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. As the Company continues to evaluate 
the Tax Cuts and Jobs Act, the Company has made a provisional determination that it is indefinitely reinvested in its UK 
business, and therefore will not provide for any deferred US taxes on the earnings of the UK business. The Company has 
also made a provisional determination that it is not permanently reinvested in its Canadian business and therefore has 
recognized deferred tax liabilities of $3 million as of December 31, 2017 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 2013 and state, local or foreign taxing authorities for tax years through 2012. Various other 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.

The total unrecognized compensation cost related to nonvested awards was $32 million at December 31, 2017 and is 
expected to be recognized over a weighted-average period of 1.6 years.

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, 2017, 6,416,547 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

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:

Grant date fair value
Volatility (1)
Risk-free rate (2)
Expected dividend yield
Expected term (in years) (3)

Equity Awards Granted by Seller of CDW UK

The Company issued 1,634,809 shares of CDW common stock as part of the consideration transferred to certain sellers 
for the acquisition of CDW UK. One of the sellers granted 608,706 stock options to certain CDW UK coworkers over 
his shares of CDW common stock received in this transaction. The options are not dilutive for purposes of calculating 
diluted weighted-average shares outstanding as the underlying shares were issued as part of the consideration transferred 
and are included within basic weighted-average shares outstanding since the acquisition date. The weighted average grant 
date fair value of the stock options was $22 million or $35.93 per option. The grant date fair value of the options was 
determined by calculating the fair value of the common stock that was issued which will eventually settle these options. 
The exercise price of these stock options is $0.01. The fair value of these stock options has been accounted for as post-
combination stock-based compensation, as service is required for the coworkers to retain the awards, and is being amortized 
over the weighted-average requisite service period. Options that are forfeited prior to vesting will not be available for 
future option issuances and will revert as consideration to the seller. For further information regarding the acquisition, 
see Note 3 (Acquisition).

Earnings Per Share

The numerator for both basic and diluted earnings per share is Net income. The denominator for basic earnings per share 
is the weighted-average shares outstanding during the period.

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, 2017, 2016 and 2015, the amounts expensed 
for these plans were $20 million, $23 million and $20 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.

Restricted Debt Unit Plan

On March 10, 2010, the Company established the Restricted Debt Unit Plan (the “RDU Plan”), an unfunded nonqualified 
deferred compensation plan. Compensation expense related to the RDU Plan was $2 million, $2 million and $5 million
for the years ended December 31, 2017, 2016 and 2015, respectively.  On September 15, 2017, the Company settled the 
RDU Plan. The total payment made on September 15, 2017 was $31 million, which settled the obligation in full.

16. 

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, 2017, 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.

On October 29, 2015, the Company learned of an investigation by the SEC of the Company’s vendor partner program 
incentives. On May 19, 2017, the SEC Staff informed the Company that the SEC has concluded its investigation and 
does not intend to recommend an enforcement action. The investigation did not have any impact on the Company’s 
financial condition or result of operations other than customary costs related to the Company’s cooperation with the 
investigation.

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 Canada and CDW UK, both of which do 
not meet the reportable segment quantitative thresholds and, accordingly, are included in an all other category (“Other”). 
Effective January 1, 2016, CDW Advanced Services is no longer an operating segment. Its results have been allocated 
to the Corporate, Small Business and Public segments to align the Company's financial reporting with the manner in 
which the Chief Operating Decision-Maker assesses performance and makes resource allocation decisions. Segment 
information reported in prior periods has been reclassified to conform to the current period presentation.

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, Income from operations 
and Adjusted EBITDA, a non-GAAP measure as defined in the Company’s credit agreements. However, the Company 
has concluded that Income from operations 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.

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, 
2017. 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, 2017, 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, 2017

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, 2017, 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, 2017, 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, 2017 and 2016, 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, 2017, and the related notes and the financial statement schedule listed in the Index at Item 15 (a) (2) and our 
report dated February 28, 2018 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 safe harbor provisions of the Private Securities Litigation 
Reform Act of 1995, including without limitation statements 
regarding the future financial performance of CDW. These 
statements involve risks and uncertainties that could cause 
actual results to differ materially from those described in such 
statements. These risks and uncertainties include, among others, 
the risk factors identified from time to time in CDW Corporation’s 
Forms 10-K, Forms 10-Q and other reports and filings with the 
Securities and Exchange Commission. Although CDW believes that 
the expectations reflected in such forward-looking statements 
are reasonable, it can give no assurance that such expectations 
will prove to have been correct. CDW undertakes no obligation to 
update or revise any forward-looking statement, whether 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 
income before income taxes, Non-GAAP net income, Non-GAAP 
net income per diluted share, Organic net sales growth (defined as 
net sales excluding the impact of current period acquisitions) and 
Organic net sales growth on a constant currency basis (defined 
as organic net sales growth excluding the impact of currency 
translation on organic sales compared to the prior period) 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 CDW’s 
operating performance and cash flows, including its ability to meet 
its future debt service, capital expenditures and working capital 
requirements. CDW also believes that adjusted EBITDA provides 
helpful information as it is the primary measure used in certain key 
covenants and definitions contained in CDW’s credit agreements. 
A reconciliation of each non-GAAP financial measure to the 
applicable most comparable GAAP financial measure is included 
on CDW’s investor relations website at http://investor.cdw.com/
financials.cfm. 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.
