dear fellow shareholders

2017 was a milestone year for our company. Our 
commitment  to  providing  customers  around  the 
world  with  best-in-class,  innovative  products  has 
solidified  our  position  as  a  leading  global  payment 
technology  provider. 
I  am  encouraged  by  the 
achievements we made last year. But, I am even more 
proud of our team for delivering  exceptional  value 
to the global marketplace.

At  the  beginning  of  the  year,  we  established  our 
strategic  pillars  that  serve  as  the  foundation  of  our 
path forward: building upon our best-in-class growth 
engine, leading through superior technology, driving 
scale  through  exceptional  execution  and  leveraging 
our culture to attract and retain the best employees. 
Our successful execution of all of these pillars allowed 
us  to  deliver  strong  results  in  2017,  underscored  by 
record annual revenue. We rolled out an array of new 
products,  achieved  our  full  synergy  targets  for  EFS 
well ahead of schedule and received the Great Place 
to Work® certification on our first submission.

Our  record  revenue  performance  was  underpinned 
by  significant  new  contract  signings  and  renewals 
throughout  the  year.  The  sophistication  of  our 
products,  combined  with  our  commitment  to 
enhancing our offerings, allowed us to win business 
with marquee names across all three of our business 
segments  including:  Verizon,  Chevron,  Autozone, 
Amadeus  (Brazil),  Bank  of  America,  Conduit,  and 
Infinisource. This not only speaks to how our products 
resonate  in  the  marketplace,  but  it  also  provides  us 
with  a  solid  foundation  for  continued  momentum 
and growth in 2018.

Our success has been, and will continue to be, driven 
by  our  people  and  our  technology.  This  year,  we 
released  the  WEX  Crossroads  product,  which  is  a  
one-card  closed-loop  solution.  This  unique  offering 

leverages a combination of WEX and EFS technologies. 
We also acquired certain net assets of AOC Solutions, 
a  key  technology  provider  for  our  virtual  card 
product,  which  expands  our  product  capabilities 
while  reducing  costs.  Additionally,  our  focus  on 
customer  personalization  and  data  intelligence  led 
to the addition of roughly 350 features to our Health 
platform,  driving  mobile  app  usage  up  over  100% 
during the year. 

Among many successes last year, we initiated a plan 
to  become  certified  as  a  Great  Place  to  Work®,  and 
achieved  certification.  Our  employees  take  pride  in 
their work, which creates an environment that fosters 
growth  and  creativity.  I  believe  that  our  culture  is  a 
differentiator  both  in  attracting  and  developing 
talent as well as in winning and retaining business.

remain 

forward,  we  will 

Looking 
focused  on 
executing  against  our  strategic  objectives.  WEX  is 
more  diverse  than  ever  before  with  a  growing  base 
of  long-term  customers  that  provides  a  strong  base 
of  recurring  revenue.  In  addition,  we’ve  won  and 
expanded  valuable  partnerships  while  maintaining 
the  industry’s  lowest  attrition  rates,  which  will  serve 
as  the  foundation  for  sustainable  long-term  growth. 
We’re encouraged by the contributions of all three of 
our business segments to our growth engine this year, 
as well as the momentum we bring into 2018.

I  would  like  to  thank  our  employees  for  their  hard 
work and dedication, and our shareholders for their 
continued  investment  in  and  support  of  WEX.  I 
look  forward  to  our  continued  prosperity  in  2018  
and beyond.

Adjusted net income attributable to shareholders

The Company’s non-GAAP adjusted net income excludes unrealized gains and losses on derivatives, net foreign currency remeasurement gains and losses, acquisition-related ticking fees, acquisition-related intangible amortization, 
other acquisition and divestiture related items, stock-based compensation, restructuring and other costs, gain on divestiture, a one-time vendor settlement, debt restructuring and debt issuance cost amortization, non-cash adjustments 
related to tax receivable agreement, reserves for regulatory penalties, adjustments attributed to our non-controlling interest and certain tax related items. In addition, for the year ended December 31, 2017, we have excluded certain 
impairment charges and asset write-offs as described below.

Although adjusted net income is not calculated in accordance with GAAP, this non-GAAP measure is integral to the Company’s reporting and planning processes and the chief operating decision maker of the Company uses adjusted 
operating income to allocate resources among our operating segments. The Company considers this measure integral because it excludes the above-specified items that the Company’s management excludes in evaluating the 
Company’s performance. Specifically, in addition to evaluating the Company’s performance on a GAAP basis, management evaluates the Company’s performance on a basis that excludes the above items because:

•   Exclusion of the non-cash, mark-to-market adjustments on derivative instruments, including fuel-price related derivatives and interest rate swap agreements, helps management identify and assess trends in the Company’s underlying 
business that might otherwise be obscured due to quarterly non-cash earnings fluctuations associated with these derivative contracts. The non-cash, mark-to-market adjustments on derivative instruments are difficult to forecast 
accurately, making comparisons across historical and future quarters difficult to evaluate.

•  Net foreign currency gains and losses primarily result from the remeasurement to functional currency of cash, receivable and payable balances, certain intercompany notes denominated in foreign currencies and any gain or loss on 

foreign currency hedges relating to these items. The exclusion of these items helps management compare changes in operating results between periods that might otherwise be obscured due to currency fluctuations.

•  The Company considers certain acquisition-related costs, including certain financing costs, ticking fees, investment banking fees, warranty and indemnity insurance, certain integration related expenses and amortization of acquired 
intangibles, as well as gains and losses from divestitures to be unpredictable, dependent on factors that may be outside of our control and unrelated to the continuing operations of the acquired or divested business or the Company. 
In addition, the size and complexity of an acquisition, which often drives the magnitude of acquisition-related costs, may not be indicative of such future costs. The Company believes that excluding acquisition-related costs and gains 
or losses of divestitures facilitates the comparison of our financial results to the Company’s historical operating results and to other companies in our industry.

•  Stock-based compensation is different from other forms of compensation, as it is a non-cash expense. For example, a cash salary generally has a fixed and unvarying cash cost. In contrast, the expense associated with an equity-based 
award is generally unrelated to the amount of cash ultimately received by the employee, and the cost to the Company is based on a stock-based compensation valuation methodology and underlying assumptions that may vary over time.
•   Restructuring and other costs include employee termination benefits from certain identified initiatives to further streamline the business, improve the Company’s efficiency, create synergies and to globalize the Company’s operations, 
all with an objective to improve scale and increase profitability going forward. We exclude these items when evaluating our continuing business performance as such items are not consistently occurring and do not reflect expected 
future operating expense, nor provide insight into the fundamentals of current or past operations of our business.

•   Impairment charges and asset write-offs represent non-cash asset write-offs related to the following:

Impairment of certain prepaid services following a strategic decision to in-source certain technology functions.
Impairments of certain payment processing software following the acquisition of AOC and as part of our ongoing platform consolidation strategy, designed to ensure we continue to deliver superior technology to our customers. 

•   These charges do not reflect recurring costs that are relevant to our continuing operations. The Company believes that excluding these nonrecurring expenses facilitates the comparison of our financial results to the Company’s  
    historical operating results and to other companies in our industry.
•   Vendor settlement represents a payment in exchange for the release of potential claims related to insourcing certain technology, and does not reflect recurring costs that would be relevant to the continuing operations of the 

Company. The Company believes that excluding this nonrecurring expense facilitates the comparison of our financial results to the Company’s historical operating results and to other companies in our industry.

•   Debt restructuring and debt issuance cost amortization are non-cash items that are unrelated to the continuing operations of the Company. Debt restructuring costs are not consistently occurring and do not reflect expected future 
operating expense, nor provide insight into the fundamentals of current or past operations of our business. In addition, since debt issuance cost amortization is dependent upon the financing method which can vary widely company 
to company, we believe that excluding these costs helps to facilitate comparison to historical results as well as to other companies within our industry.

•   The adjustments attributable to non-controlling interests, including adjustments to the redemption value of a non-controlling interest, and the non-cash adjustments related to our tax receivable agreement have no significant impact 

on the ongoing operations of the business.

•   Regulatory reserves reflect charges related to the impact of a regulatory action which resulted in WEX paying a penalty in 2016. We have excluded this item when evaluating our continuing business performance as it is not consistently 

recurring and does not reflect an expected future operating expense, nor provide insight into the fundamentals of the current or past operations of our business.

•   The tax related items are the difference between the Company’s U.S. GAAP tax provision and a pro forma tax provision based upon the Company’s adjusted net income before taxes as well as the impact from certain discrete tax items. 

The methodology utilized for calculating the Company’s adjusted net income tax provision is the same methodology utilized in calculating the Company’s U.S. GAAP tax provision.

4

For the same reasons, WEX believes that adjusted net income may also be useful to investors as one means of evaluating the Company’s performance. However, because adjusted net income is a non-GAAP measure, it should not be 
considered as a substitute for, or superior to, net income, operating income or cash flows from operating activities as determined in accordance with GAAP. In addition, adjusted net income as used by WEX may not be comparable to 
similarly titled measures employed by other companies.

ITEM 1. BUSINESS

Our Company

PART I

WEX Inc. is a leading provider of corporate payment solutions. WEX Inc. began operations in 1983 as a Maine corporation 
and was acquired in February 1996 by an entity that subsequently merged with HFS Incorporated to form Cendant Corporation 
in December 1997. In June 1999, our predecessor, Wright Express, was sold to Avis Group Holdings, Inc., which was acquired 
by Cendant Corporation in March 2001. In anticipation of our initial public offering, the Company’s operations were transferred 
to a Delaware LLC, which was converted into a Delaware corporation in 2005 in conjunction with our initial public offering on 
February 16, 2005 (NYSE:WEX). Over the past 30 years, we have expanded the scope of our business from a fleet payment 
provider into a multi-channel provider of corporate payment solutions.

We currently operate in three business segments: Fleet Solutions, Travel and Corporate Solutions, and Health and Employee 
Benefit Solutions. Our products and services enable us to provide exceptional payment security and control across a wide spectrum 
of payment sectors. 

Fleet Solutions provides customers with fleet vehicle payment processing services specifically designed for the needs of 
commercial and government fleets. During the year ended December 31, 2017, Fleet Solutions revenue represented approximately 
66 percent of our total revenue. As of December 31, 2017, the segment services over 11.4 million vehicles. Management estimates 
that WEX fleet cards are accepted at over 90 percent of fuel locations in each of the United States and Australia. With the acquisition 
of our European Fleet business in December 2014, WEX fleet cards are accepted at all ExxonMobil stations throughout Europe. 

Travel  and  Corporate  Solutions  focuses  on  the  complex  payment  environment  of  business-to-business  payments, 
providing customers with payment processing solutions for their corporate payment and transaction monitoring needs. Travel and 
Corporate Solutions revenue, which represented approximately 18 percent of our total revenue during the year ended December 31, 
2017, is  generated primarily in the online travel market. The Travel and Corporate Solutions segment also includes payment 
solutions for payables and travel expenses. The segment has operations in North America, Europe, South America and Asia-Pacific.

Table of Contents

Health and Employee Benefit Solutions represented approximately 16 percent of our total revenue during the year ended 
December 31, 2017. During 2015, our wholly-owned subsidiary Evolution1 acquired Benaissance, a provider of integrated SaaS 
technologies and services for the Consolidated Omnibus Budget Reconciliation Act (“COBRA”) and healthcare premium billing, 
payment and workflow management, to complement our healthcare financial technology platform products and services. During 
2016, we collectively rebranded Evolution1 and Benaissance as WEX Health. The Health and Employee Benefit Solutions segment 
also includes payroll related benefits offered to customers in Brazil.

The Company’s U.S. operations include WEX Inc. and our wholly-owned subsidiaries WEX Bank, WEX FleetOne, EFS 
and WEX Health. Our international operations include our wholly-owned operations, WEX Fuel Cards Australia, WEX Prepaid 
Cards Australia, WEX Canada, WEX New Zealand, WEX Asia, WEX Europe Limited, UNIK S.A., a Brazil-based company that 
we refer to as "WEX Latin America," and a controlling interest in WEX Europe Services Limited and its subsidiaries.

WEX Bank, a Utah industrial bank incorporated in 1998, is a FDIC insured depository institution. The functions performed 
at WEX Bank contribute to the U.S. and Canadian operations of Fleet Solutions and the operations of Travel and Corporate Solutions 
by providing a funding mechanism, among other services. With our ownership of WEX Bank, we have access to low-cost sources 
of capital. WEX Bank raises capital primarily through the issuance of brokered deposit accounts and provides the financing and 
makes credit decisions that enable the Fleet Solutions and Travel and Corporate Solutions segments to extend credit to customers. 
WEX Bank approves customer applications, maintains appropriate credit lines for each customer, is the account issuer, and is the 
counterparty for the customer relationships for most of our programs in the U.S. Operations such as sales, marketing, merchant 
relations, customer service, software development and IT are performed as a service within our organization but outside of WEX 
Bank. WEX Bank’s primary regulators are the Utah Department of Financial Institutions (“Utah DFI”) and the FDIC. The activities 
performed by WEX Bank are integrated into the operations of our Fleet Solutions and Travel and Corporate Solutions segments. 

Developments

Prior to our initial public offering in 2005, the Company’s growth had primarily been organic. Our growth in the past 

several years has been supplemented by acquisitions. Our acquisitions over the last few years include: 

•  Effective October 18, 2017, we acquired certain assets and assumed certain liabilities of AOC, a provider of commercial 
payments  technology. This  acquisition  will  broaden  our  capabilities,  increase  our  pool  of  employees  with  payments 
platform experience and allow us to evolve with the needs of our customers and partners through the use of AOC’s 
payments processing technology platforms.

•  On July 1, 2016, we acquired EFS, a provider of customized payment solutions for fleet and corporate customers with a 
focus on the large and mid-sized over-the-road fleets, in order to expand our customer footprint and utilize EFS's technology 
to better serve the needs of our fleet customers.

•  On November 18, 2015, our wholly-owned subsidiary Evolution1 acquired Benaissance, a provider of integrated SaaS 
technologies  and  services  for  COBRA  and  healthcare  premium  billing,  payment  and  workflow  management,  to 
complement our healthcare payments products and services.

•  On August 31, 2015, we acquired the remaining 49 percent ownership in UNIK S.A., a majority-owned subsidiary prior 

to this transaction.

•  On December 1, 2014, our majority owned subsidiary, WEX Europe Services Limited, acquired the assets of ExxonMobil's 
European commercial fuel card program, which includes operations, funding, pricing, sales and marketing in nine countries 
in Europe.

•  On July 16, 2014, we acquired Evolution1, a provider of financial technology platform solutions within the healthcare 

industry.

•  On October 15, 2013, our majority-owned subsidiary WEX Latin America acquired FastCred, a provider of fleet cards 

to the heavy truck or over-the-road segment of the fleet market in Brazil.

During the year ended December 31, 2017, the Company sold $8.9 million in net assets of its Telapoint business for 
proceeds of  $29.9 million, which resulted in a pre-tax book gain of $21.0 million. The divestiture was not material to the Company's 
annual revenue, net income or earnings per share. The Company does not view this divestiture as a strategic shift in its operations.

On January 7, 2015, we sold the operations of rapid! PayCard for $20.0 million, which resulted in a pre-tax book gain of 
$1.2 million. Our primary focus in the U.S. continues to be in the fleet, travel, and healthcare industries. As such, we divested the 
operations of rapid! PayCard, which were not material to our annual revenue, net income or earnings per share.

Table of Contents

On July 29, 2014, we sold our Pacific Pride subsidiary for $49.7 million, which resulted in a pre-tax book gain of $27.5 
million. The Company decided to sell the operations of Pacific Pride as it did not align with the long-term strategy of the core fleet 
business. The Company entered into a multi-year agreement with the buyer that will continue to allow WEX branded card acceptance 
at Pacific Pride locations.

Competitive Strengths 

We believe the following strengths distinguish us from our competitors: 

•  Our proprietary closed-loop fuel networks in the U.S. and Australia are among the largest in each country. We describe 
our fleet payment processing networks as “closed-loop” because we have a direct contractual relationship with both the 
merchant and the fleet, and only WEX transactions can be processed on these networks. We have built networks that 
management estimates to provide coverage to over 90 percent of fuel locations in the U.S. and Australia, as well as wide 
acceptance in Europe and Brazil. This provides our customers with the convenience of broad acceptance.

•  Our proprietary closed-loop fuel networks provide us with access to a higher level of fleet-specific information and control 
as compared to what is typically available on an open-loop network. This provides high-level purchase controls at the 
point of sale, including the flexibility of allowing fleets to restrict purchases and receive automated alerts. Additionally, 
we have the ability to refine the information reporting provided to our fleet customers and customers of our strategic 
relationships.

•  We offer a differentiated set of products and services, including security and purchase controls, to allow our customers 
and the customers of our strategic relationships to better manage their vehicle fleets. We provide customized analysis and 
reporting on  the  efficiency  of fleet  vehicles and the  purchasing behavior  of  fleet vehicle drivers. We  make this  data 
available to fleet customers through both traditional reporting services and sophisticated web-based data analysis tools. 

•  Our long-standing strategic relationships, multi-year contracts and high contract renewal rates have contributed to the 
stability and recurring nature of our revenue base. We believe that we offer a compelling value to our customers relative 
to our competitors given the breadth and quality of our products and services and our deep understanding of our customers’ 
operational  needs.  We  have  a  large  installed  customer  base,  with  more  than  11.4  million  vehicles  serviced  as  of 
December 31, 2017 and co-branded strategic relationships with five of the largest U.S. fleet management providers and 
with dozens of oil companies that use our private label solutions. Our wide site acceptance, together with our private-
label portfolios and value-added product and service offerings, drive high customer satisfaction levels, with a U.S. fleet 
retention rate in excess of 97 percent (based on the 2017 rate of voluntary customer attrition). 

•  Our capabilities in the over-the-road segment of the market enhance our ability to serve fleet customers who operate both 
heavy duty trucks and cars or light duty vehicles in the U.S. and Canada as well as to blend the small fleet and private 
label businesses for greater scale. The July 2016 acquisition of EFS expanded our customer footprint within the over-
the-road market segment.

•  Our purchase of ExxonMobil's commercial fuel card program, which uses a closed-loop network in Europe, combined 
with the long term supply agreement to serve the current and future European Fleet business, provides us with a strong 
foundation in the large European fleet market.

•  Our travel and corporate payment products offer corporate customers enhanced security and control for complex payment 
needs, while the addition of the EFS Corporate Payment Solutions set of products expands our presence into the electronic 
accounts payable segment of the market. Our strategic relationships include four of the largest online travel agencies in 
the world. We continue to expand our online travel payment solution capabilities and geographies, which currently include 
North America, Europe, South America and Asia-Pacific. As of December 31, 2017, we settle transactions in 21 different 
currencies. 

•  The demand for our payment processing, account servicing and transaction processing services combined with significant 
operating scale has historically driven strong revenue growth and earnings potential. We have an extensive history of 
organic revenue growth driven by our various marketing channels, our extensive network of fuel and service providers, 
and our growth in transaction volume. Further, we have completed a number of strategic acquisitions to expand our 
product and service offerings, which have contributed to our revenue growth and diversification of our products and 
services.

•  WEX Health has become a leading provider of cloud-based healthcare payments technology, through the acquisition of 
Evolution1  in  2014  and  Benaissance  in  2015.  Our  large  partner  network  expands  our  opportunities  in  the  growing 

5

 
 
Table of Contents

healthcare  financial  technology  platform  market.  WEX  Health  benefits  from  both  high  retention  rates  and  revenue 
predictability as a result of its SaaS business model.

•  We have an enterprise-wide risk management program that helps us identify and manage inherent risks related to our 
liquidity, extension of credit and interest rates. Our ownership of WEX Bank provides us with access to low cost sources 
of capital, which provide liquidity to fund our short-term card receivables. We have maintained a long record of low credit 
losses due to the short-term, non-revolving credit issued to our customer base. Our credit risk management program is 
enhanced  by  our  proprietary  scoring  models,  managing  credit  lines  and  early  suspension  policy.  Interest  rate  risk  is 
managed  through  diversified  funding  sources  at  WEX  Bank  including  interest  bearing  money  market  deposits  and 
certificates of deposit with varying maturities. Some of our merchant contracts include some ability to raise rates if interest 
rates rise.

•  We have an experienced and committed management team that has substantial industry knowledge and a proven track 
record of financial success. The team has been successful in driving strong growth with consistent operating performance. 
We believe that our management team positions us well to continue successfully implementing our growth strategy and 
capturing operating efficiencies. 

Strategy 

Our Company’s path forward will be shaped by the following three strategic priorities:  

•  Drive continued growth.  We continue to see significant organic growth opportunities across each of our Fleet 
Solutions, Travel and Corporate Solutions, and Health and Employee Benefit Solutions segments. We seek to 
capture this growth opportunity through our product excellence, marketing capabilities, sales force productivity, 
and  revenue  management  practices. Our  acquisition  strategy  will  complement  our  organic  growth  by  both 
enhancing scale and adding differentiation to our current offerings.

•  Lead through superior technology.  We have built and differentiate ourselves in the marketplace on a distinctive 
set of technologies in our Fleet Solutions, Travel and Corporate Solutions, and Health and Employee Benefit 
Solutions segments. As our markets continue to evolve, our ability to quickly and cost effectively innovate and 
deliver superior technological solutions continue to set us apart from our peers.

• 

Set standard for operational excellence.  We stand apart in our segments by reliably delivering the best solutions 
to  our  partners  and  customers. We  are  continually  optimizing  our  cost  structure  and  capturing  new  revenue 
synergies across our lines of business. Gains in operational efficiency simplify our business, making us more 
nimble to capture market opportunities as they arise.

Overview

FLEET SOLUTIONS SEGMENT 

The Fleet Solutions segment provides customers with fleet vehicle payment processing services specifically designed for 
the needs of commercial and government fleets. We are a leading provider of fleet vehicle payment processing services with over 
11.4 million vehicles at year end using our fleet payment solutions to purchase fuel and maintenance services. Our competitive 
advantages in the fleet market include brand strength and product offerings, commitment to customer satisfaction and a financing 
model with attractive credit terms. Our fleet products are based upon proprietary technology with closed-loop networks in the 
U.S., Australia and Europe and wide site acceptance domestically and abroad.

As part of our value proposition, we deliver security through individualized driver identification and real-time transaction 
updates, purchase controls and sophisticated reporting tools. We collect a broad array of information at the point of sale, including 
the amount of the expenditure, the identity of the driver and vehicle, the odometer reading, the identity of the fuel or vehicle 
maintenance provider and the items purchased. We use this information to provide customers with analytical tools to help them 
effectively manage their vehicle fleets and control costs. We deliver value to our customers by providing customized offerings for 
accepting merchants, processing payments and providing information management products and services to fleets. 

Our proprietary closed-loop networks allow us to provide our customers with highly detailed, fleet-specific information 
and customized controls that are not typically available on open-loop networks, such as limiting purchases to fuel only and restricting 
the time of day and day of the week when fuel is purchased. Our network also enables us to avoid dependence on third-party 
processors. In addition, our relationships with both fleets and merchants enable us to provide security and controls and provide 
customizable reporting. 

The following illustrates our proprietary closed-loop network:

Payment processing transactions represent a majority of the revenue stream in the Fleet Solutions segment. In a payment 
processing  transaction,  we  extend  short-term  credit  to  the  fleet  customer  and  pay  the  purchase  price  for  the  fleet  customer’s 
transaction, less the payment processing fees we retain, to the merchant. Revenue from our WEX Europe Services operations is 
primarily generated by transactions where our revenue is derived from the difference between the negotiated price of the fuel from 
the supplier and the price charged to the fleet customer. We collect the total purchase price from the fleet customer, normally within 
30 days from the billing date.

The following illustration depicts our business process for a typical WEX direct network domestic fuel payment processing 

transaction:

With  the  acquisition  of  EFS,  we  have  diversified  our  market  position  in  the  over-the-road  fleet  segment.  We  offer 

customizable over-the-road fleet payment solutions that address comprehensive business needs including:  

•  Real-time interactive interfaces delivering data integrity through a seamless user interface

•  Alternative payment and money transfer options

•  Comprehensive settlement solutions

•  Real-time reports and analytics for compliance and cost-optimization

• 

Fuel reconciliation and mobile optimization tools

Products and Services 

Payment processing fees are based on a percentage of the aggregate dollar amount of the customer’s purchase, a fixed 
amount per transaction or a combination of both. Additionally, payment processing revenue related to our WEX Europe Services 
operations is specifically derived from the difference between our negotiated price of the fuel from the supplier and the agreed 
upon price paid by the fleets. In 2017, we processed approximately 430 million payment processing transactions, compared to 386 
million  payment  processing  transactions  in  2016.  Additionally,  we  receive  revenue  from  account  servicing  fees,  factoring 
receivables and finance fees. 

We offer the following services: 

•  Customer service, account activation and account retention: We offer customer service, account activation and 
account  retention  services  to  fleets  and  fleet  management  companies  and  the  fuel  and  vehicle  maintenance 
providers on our network. Our services include promoting the adoption and use of our products and programs 
and account retention programs on behalf of our customers and partners. 

•  Authorization and billing inquiries and account maintenance: We handle authorization and billing questions, 
account changes and other issues for fleets through our dedicated customer contact centers, which are available 

8

 
 
 
 
Table of Contents

24 hours a day, seven days a week. Fleet customers also have self-service options available to them through our 
websites. 

•  Premium fleet services: We assign designated account managers to businesses and government agencies with 
large  fleets.  These  representatives  have  in-depth  knowledge  of  both  our  programs  and  the  operations  and 
objectives of the fleets they service. 

•  Credit and collections services: We have developed proprietary account approval, credit management and fraud 
detection programs. Our underwriting model produces a proprietary score, which we use to predict the likelihood 
of an account becoming delinquent within 12 months of activation. We also use a credit maintenance model to 
manage ongoing accounts, which helps us to predict the likelihood of account delinquency over an ongoing 18-
month time horizon. We have developed a collections scoring model that we use to rank and prioritize past due 
accounts for collection activities. We also employ fraud specialists who monitor accounts, alert customers and 
provide case management expertise to minimize losses and reduce program abuse. 

•  Merchant  services:  Our  representatives  work  with  fuel  and  vehicle  maintenance  providers  to  enroll  these 
providers in our network, test all network and terminal software and hardware, and to provide training on our 
sale, transaction authorization and settlement processes. 

•  ClearView analytics platform: We provide customers with access to a web-based data analytics platform that 
offers insights to fleet managers, including integrating and analyzing business fleet fuel purchases to uncover 
fraud, manage product type controls and identify cost saving opportunities. 

• 

SmartHub mobile app: This mobile application gives business managers access to their account information 
anytime and anywhere, including the ability to view and make bill payments, access transaction details and 
control the status of driver fuel cards. As a result, this offering helps customers improve efficiencies, reduce late 
fees, gain valuable insights and control unauthorized driver spending. 

Information Management 

We provide standard and customized information to customers through monthly vehicle analysis reports, custom reports 
and our websites. We also alert customers of unusual transactions or transactions that fall outside of pre-established parameters. 
Customers  can  access  their  account  information  through  our  website  including  account  history  and  recent  transactions,  and 
download the related details. In addition, fleet managers can elect to be notified by email when limits are exceeded in specified 
purchase categories, including limits on transactions within a time range and gallons per day.

Marketing Channels 

We  market  our  fleet  products  and  services  both  directly  and  indirectly  to  commercial  and  government  vehicle  fleet 
customers with small, medium and large fleets, and over-the-road, long haul fleets. Our product suite includes payment processing 
and transaction processing services, WEX branded fleet cards in North America and Motorpass/Motorcharge-branded fleet cards 
in Australia. As of December 31, 2017, our direct line of business serviced 4.0 million vehicles. As of the same period, our over-
the-road line of business serviced 1.0 million vehicles, marketed under the EFS, EFS Transportation Services, T-Chek and Fleet 
One brands. 

We also market our products and services indirectly through co-branded and private label relationships. With a co-branded 
relationship product, we market our products and services for, and in collaboration with, both fuel providers and fleet management 
companies using their brand names and our logo on a co-branded fleet card. These companies seek to offer our payment processing 
and information management services as a component of their total offering to their fleet customers. As of December 31, 2017, 
our co-branded marketing channel serviced 2.1 million vehicles. 

Our private label programs market our products and services for, and in collaboration with, fuel retailers, using only their 
brand names. The fuel retailers with which we have formed strategic relationships offer our payment processing and information 
management products and services to their fleet customers in order to establish and enhance customer loyalty. These fleets use 
these products and services to purchase fuel at locations of the fuel retailer with whom we have the private label relationship. As 
of December 31, 2017, our private label marketing channel serviced 4.3 million vehicles.

Overview

TRAVEL AND CORPORATE SOLUTIONS SEGMENT 

Our Travel and Corporate Solutions segment is comprised of our virtual and prepaid products with which we provide 
innovative corporate purchasing and payment capabilities that can be integrated with our customers’ internal systems to streamline 
their corporate payments, accounts payable and reconciliation processes. 

Products and Services 

The Travel and Corporate Solutions segment allows businesses to centralize purchasing, simplify complex supply chain 
processes and eliminate the paper check writing associated with traditional purchase order programs. Our product suite includes 
virtual, credit, debit and prepaid products.

Our virtual card is used for transactions where no card is presented, including, for example, transactions conducted over 
the telephone, by mail, by fax or on the Internet. Our virtual card also can be used for transactions that require pre-authorization, 
such as hotel reservations. Under our virtual card programs, each transaction is assigned a unique account number with a customized 
credit limit and expiration date. These controls are in place to limit fraud and unauthorized spending. The unique account number 
limits purchase amounts and tracks, settles and reconciles purchases more easily, creating efficiencies and cost savings for our 
customers. The virtual card products offer both credit and debit options.  

Our electronic accounts payable solution utilizes virtual card payments that are both broadly accepted and highly secure. 
This product reduces manual processing costs and facilitates comprehensive payment terms management to maximize margin 
improvement, efficiency and control.

Our corporate travel and expenses card offers broad global acceptance, reduced risk of fraud and enhanced travel data, 
and is designed for organizations whose employees travel on business. We make trips easier to plan, more productive, and less 
expensive through enhanced spending controls for both the company and its travelers.

Our  prepaid  and  gift  card  products  are  offered  through  WEX  Prepaid  Card Australia  and  WEX  Europe  Limited  to 
companies throughout Australia and Europe. These products provide secure payment and financial management solutions with 
single card options, access to open or closed loop redemption, load limits and variable expirations.

The  following  illustration  depicts  our  business  process  for  a  typical  travel  virtual  card  product  transaction:

 1  Guest books a hotel through a travel website owned by an online travel company

 2  Online travel company reserves room at hotel through reservation system using a WEX virtual card number to reserve the room.

 3  Upon checkout, hotel authorizes payment using the WEX virtual card number. The WEX virtual card restricts charge to predetermined 
cost of room, incidental expenses are paid for by guest.

 4  Online travel company pays WEX. WEX earns fee by retaining percentage of the online travel company reimbursement payment.

Marketing Channels 

We market our Travel and Corporate Solutions segment products and services both directly and indirectly to new and 
existing  customers.  Our  products  are  marketed  to  commercial  and  government  organizations  and  we  use  existing  open-loop 
networks.

Overview

HEALTH AND EMPLOYEE BENEFIT SOLUTIONS SEGMENT 

Our Health and Employee Benefit Solutions segment is comprised of our healthcare payment products and SaaS platforms 
with which we provide simplified payment capabilities in a complex healthcare market as well as employee benefit products in 
Brazil. 

Products and Services 

With our healthcare payment products, we provide consumer-directed payments in the complex healthcare market. We 
partner with health plans, third-party administrators, financial institutions, payroll companies and software providers to provide a 
software as a service product to support employers' healthcare benefits programs and to administer COBRA, flexible spending, 
health saving and reimbursement accounts, and other healthcare related employee and dependent benefits. 

We currently have relationships with approximately 300,000 employers, reaching 25 million consumers. Revenue is 
generated primarily from SaaS based monthly fees to partners and interchange fees from spending on customer debit cards issued 
under flexible spending, health savings and reimbursement accounts. Cards are branded with either Visa or MasterCard and operate 
on a restricted open loop network.

Our benefit products are offered through our wholly-owned subsidiary, WEX Latin America. Employees using our benefit 
products have access to salary advances payable in up to 24 monthly installments which are secured by future salary earnings. 
These advances are funded primarily through securitization of the corresponding receivables.

Health and Employee Benefit Solutions segment revenues are generated primarily from platform usage subscription fees 

and interchange fees from spending on the WEX Health payment cards.

Marketing Channels 

We market our Health and Employee Benefit Solutions products and services to consumers through an extensive partner 
network, which includes health plans, third party administrators, financial institutions, payroll providers and software providers. 
Our employee benefit products are marketed to consumers through employers in Brazil.

Employees 

OTHER ITEMS 

As of December 31, 2017, WEX Inc. and its subsidiaries had more than 3,300 employees, of which approximately 2,500
were located in the United States. None of our U.S.-based employees are subject to a collective bargaining agreement. In Europe, 
certain  employees  are  members  of  trade  unions  or  works  councils.  In  Brazil,  certain  employees  are  members  of  unions. The 
Company  believes  that  its  relations  with  its  employees,  unions  and  work  councils  are  generally  satisfactory. This  belief  was 
reinforced by the Company being certified as a "Great Place to Work" in 2017 by Great Place to Work®.

Competition 

We have a strong competitive position in each of our segments. Our product features and extensive account management 
services are key factors behind our position in the fleet industry. We face competition in all of our segments. Our competitors vie 
with us for prospective direct fleet customers as well as for companies with which to form strategic relationships. We compete 
with  companies  that  perform  payment  and  transaction  processing  or  similar  services.  Financial  institutions  that  issue  Visa, 
MasterCard and American Express credit and charge cards currently compete against us primarily in the Fleet Solutions and Travel 
and Corporate Solutions segments. We also compete with other healthcare payment service providers.

The most significant competitive factors include the breadth of features offered, functionality, servicing capability and 
price. For more information regarding risks related to competition, see the information in Item 1A, under the heading “Our industry 
continues to become increasingly competitive, which makes it more challenging for us to maintain profit margins at historical 
levels.”

Technology 

We believe that investment in technology is a crucial step in maintaining and enhancing our competitive position in the 
marketplace. Our data center network and infrastructure is supported by secure data centers with redundant locations. We have 
data centers in various locations in the United States including South Portland, Maine and Aurora, Colorado. We also have data 
centers and infrastructure located in various locations throughout Europe, Australia, New Zealand and Brazil. 

Our  fleet  fuel-based  closed-loop  proprietary  platforms  capture  detailed  information  from  the  fuel  and  maintenance 
locations within our network. Operating a proprietary network not only enhances our value proposition, it also enables us to limit 
dependence on third-party processors and to respond rapidly to changing customer needs with system upgrades, while maintaining 
a  more  secure  environment  than  an  open-loop  network  typically  allows.  Our  virtual  card  open-loop  network  uses  internally 
developed software and third-party processors. Our infrastructure has been designed around industry-standard architectures to 
reduce downtime in the event of outages or catastrophic occurrences. At WEX Health, we maintain an integrated multi-account 
payment platform, including a mobile application. In Australia, New Zealand, Brazil and the United Kingdom, we use standalone 
platforms to support operations. 

Our secure networks are designed to isolate our databases from unauthorized access. We use security protocols among 
all applications, and our employees access critical components on a need-to-know basis. As of December 31, 2017, we have not 
experienced any material incidents in network, application or data security. We are continually improving our technology to enhance 
customer relationships and to increase efficiency and security. We also review technologies and services provided by others in 
order to maintain the high level of service expected by our customers and continue to invest in our infrastructure. 

For information regarding technology related risks, see the information in Item 1A under the headings “Our business is 
regularly subject to cyberattacks and attempted security and privacy breaches and we may not be able to adequately protect our 
information  systems,  including  the  data  we  collect  about  our  customers,  which  could  subject  us  to  liability  and  damage  our 
reputation”, “Our failure to effectively implement new technology could jeopardize our position as a leader in our industry,” “We 
are dependent on technology systems and electronic communications networks managed by third parties, which could result in 
our inability to prevent service disruptions” and “If the technologies we use in operating our business and interacting with our 
customers fail, are unavailable, or do not operate to expectations, or we fail to successfully implement technology strategies and 
capabilities in connection with our outsourcing arrangements, our business and results of operation could be adversely impacted.”

Seasonality

Our businesses are affected by seasonal variations. For example, fuel prices are typically higher during the summer and 
online travel sales are typically higher during the third quarter. In addition, we experience seasonality in our Health and Employee 
Benefits Solutions segment, as consumer spend is correlated with insurance deductibles, typically resulting in higher spend in the 
early part of the year until employees meet their deductibles.

Intellectual Property 

We rely on a combination of patent, copyright, trade secret and trademark laws, confidentiality procedures, contractual 
provisions and other similar measures to protect the proprietary information and technology used in our business. We generally 
enter into confidentiality, professional services and/or license agreements with our consultants and corporate partners and control 
access to and distribution of our technology, documentation and other proprietary information. Despite the efforts to protect our 
proprietary rights, unauthorized parties may attempt to copy or otherwise obtain the use of our products or technology that we 
consider  proprietary  and  third  parties  may  attempt  to  develop  similar  technology  independently.  We  pursue  registration  and 
protection of our trademarks in the U.S. and other countries in which we operate or plan to operate. We market our products and 
services using the WEX, Fleet One, EFS and the WEX Health Cloud brand names in the U.S., the Motorpass and Motorcharge 
brand names in Australia and the WEX Latin America brand name in Brazil.

Regulation - United States 

The Company and its affiliates are subject to certain state and federal laws and regulations, which govern insured depository 
institutions  and  their  affiliates  as  well  as  our  operations  in  the  healthcare  market.  WEX  Bank  is  subject  to  supervision  and 
examination by both the Utah DFI and the FDIC. The Company and its affiliates are subject to certain limitations on transactions 
with affiliates set forth in the Federal Reserve Act (“FRA”). The Company is subject to anti-tying provisions in the Bank Holding 
Company Act. State and Federal laws and regulations limit the loans WEX Bank may make to one borrower and the types of 
investments WEX Bank may make. 

Below is a description of the material elements of the laws, regulations, policies and other regulatory matters affecting 

the operations of WEX in the United States. 

13

 
 
 
 
 
 
 
 
Table of Contents

Exemption from Certain Requirements of the Bank Holding Company Act 

As an industrial bank organized under the laws of Utah that does not accept demand deposits that may be withdrawn by 
check or similar means, WEX Bank meets the criteria for exemption from the definition of “bank” under the Bank Holding Company 
Act. As a result, the Company is generally, except as stated above, not subject to the Bank Holding Company Act. 

Restrictions on Intercompany Borrowings and Transactions 

Sections 23A and 23B of the FRA and the implementing regulations limit the extent to which the Company can borrow 
or otherwise obtain credit from or engage in other “covered transactions” with WEX Bank. “Covered transactions” include loans 
or extensions of credit, purchases of or investments in securities, purchases of assets, including assets subject to an agreement to 
repurchase, acceptance of securities as collateral for a loan or extension of credit, or the issuance of a guarantee, acceptance, or 
letter of credit. Although the applicable rules do not serve as an outright ban on engaging in “covered transactions,” they do limit 
the amount of covered transactions WEX Bank may have with any one affiliate and with all affiliates in the aggregate. The applicable 
rules also require that the Company engage in such transactions with WEX Bank only on terms and under circumstances that are 
substantially the same, or at least as favorable to WEX Bank, as those prevailing at the time for comparable transactions with 
nonaffiliated companies. Furthermore, with certain exceptions, each loan or extension of credit by WEX Bank to the Company or 
its other affiliates must be secured by collateral with a market value ranging from 100 percent to 130 percent of the amount of the 
loan or extension of credit, depending on the type of collateral. 

The Consumer Financial Protection Bureau 

The Dodd-Frank Act established the Consumer Financial Protection Bureau (“CFPB”) to regulate the offering of consumer 
financial products or services under the federal consumer financial laws. In addition, the CFPB was granted general authority to 
prevent covered persons or service providers from committing or engaging in unfair, deceptive or abusive acts or practices under 
federal law in connection with any transaction with a consumer for a consumer financial product or service. The CFPB has broad 
rulemaking authority for a wide range of consumer protection laws. The legislation also gives the state attorneys general the ability 
to enforce applicable federal consumer protection laws. 

In addition, the Durbin Amendment to the Dodd-Frank Act provided that interchange fees that a card issuer or payment 
network receives or charges for debit transactions will now be regulated by the Federal Reserve and must be “reasonable and 
proportional” to the cost incurred by the card issuer in authorizing, clearing and settling the transaction. Payment network fees 
may not be used directly or indirectly to compensate card issuers in circumvention of the interchange transaction fee restrictions. 
In July 2011, the Federal Reserve published the final rules governing debit interchange fees. Effective in October 2011, with certain 
exemptions, debit interchange rates were capped at $0.21 per transaction with an additional component of five basis points of the 
transaction’s value to reflect a portion of the issuer’s fraud losses plus, for qualifying issuing financial institutions, an additional 
$0.01 per transaction in debit interchange for fraud prevention costs.

Brokered Deposits 

Under FDIC regulations, depending upon their capital classification, banks may be restricted in their ability to accept 
brokered deposits. “Well capitalized” banks are permitted to accept brokered deposits, but banks that are not “well capitalized” 
are not permitted to accept such deposits. The FDIC may, on a case-by-case basis, permit banks that are “adequately capitalized” 
to accept brokered deposits if the FDIC determines that acceptance of such deposits would not constitute an unsafe or unsound 
banking practice. 

Other Financial Regulatory Requirements 

WEX Bank must monitor and report unusual or suspicious account activity, as well as transactions involving amounts in 
excess of prescribed limits, as required by the Bank Secrecy Act and Internal Revenue Service regulations. The USA PATRIOT 
Act of 2001 substantially broadened the scope of U.S. anti-money laundering laws and regulations by imposing significant new 
compliance and due diligence obligations, identifying new crimes and penalties and expanding the extra-territorial jurisdiction of 
the United States. The United States Treasury Department has proposed and, in some cases, issued a number of implementing 
regulations which impose obligations on financial institutions to maintain appropriate policies, procedures and controls to detect, 
prevent and report money laundering and terrorist financing and to verify the identity of their customers. Certain of those regulations 
impose specific due diligence requirements on financial institutions that maintain correspondent or private banking relationships 
with non-U.S. financial institutions or persons. Failure of a financial institution to maintain and implement adequate programs to 
combat money laundering and terrorist financing could have serious legal and reputational consequences for the institution. 

The U.S. federal government has imposed economic sanctions that affect transactions with designated foreign countries, 
nationals and others. These sanctions, which are administered by the United States Treasury’s Office of Foreign Assets Control 

14

 
 
 
 
 
 
 
Table of Contents

(“OFAC”), take many different forms but generally include one or more of the following elements: (i) restrictions on trade with 
or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned 
country and prohibitions on “U.S. persons” engaging in financial transactions relating to making investments in, or providing 
investment-related advice or assistance to, a sanctioned country; and (ii) a blocking of assets in which the government or specially 
designated nationals of the sanctioned country have an interest, by prohibiting transfers of property subject to U.S. jurisdiction 
(including property in the possession or control of U.S. persons). Blocked assets (for example, property and bank deposits) cannot 
be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. Failure to comply with these sanctions 
could have serious legal and reputational consequences. 

Under the Financial Services Modernization Act of 1999, also referred to as the “Gramm-Leach-Bliley Act" (or “GLBA”), 
the  Company  and  WEX  Bank  are  required  to  maintain  a  comprehensive  written  information  security  program  that  includes 
administrative, technical and physical safeguards relating to customer information. However, this requirement does not generally 
apply to information about companies or about individuals who obtain financial products or services for business, commercial, or 
agricultural purposes. The GLBA also requires the Company and WEX Bank to provide initial and annual privacy notices to 
customers that describe in general terms their information sharing practices. If the Company and WEX Bank intend to share 
nonpublic personal information about customers with affiliates and/or nonaffiliated third parties, they must provide customers 
with a notice and a reasonable period of time for each consumer to “opt out” of any such disclosure. In addition to U.S. federal 
privacy laws, states also have adopted statutes, regulations and other measures governing the collection and distribution of nonpublic 
personal information about customers. In some cases these state measures are preempted by federal law, but if not, the Company 
and WEX Bank must monitor and comply with such laws in the conduct of its business. 

Escheat Laws

We are subject to unclaimed or abandoned property state laws in the United States and in certain foreign countries that 
require us to transfer to certain government authorities the unclaimed property of others that we hold when that property has been 
unclaimed for a certain period of time. Moreover, we are subject to audit by state and foreign regulatory authorities with regard 
to our escheatment practices.

Restrictions on Dividends 

WEX Bank is subject to various regulatory requirements relating to the payment of dividends, including requirements to 
maintain  capital  above  regulatory  minimums. A  banking  regulator  may  determine  that  the  payment  of  dividends  would  be 
inappropriate and could prohibit payment. Further, WEX Bank may not pay a dividend if it is undercapitalized or would become 
undercapitalized as a result of paying the dividend. Utah law permits WEX Bank to pay dividends out of the net profits of the 
industrial bank after providing for all expenses, losses, interest, and taxes accrued or due, but if WEX Bank’s surplus account is 
less than 100 percent of its capital stock, WEX Bank must transfer up to 10 percent of its net profits to the surplus account prior 
to the payment of any dividends. 

 Company Obligations to WEX Bank 

Any non-deposit obligation of WEX Bank to the Company is subordinate, in right of payment, to deposits and other 
indebtedness of WEX Bank. In the event of the Company’s bankruptcy, any commitment by the Company to a federal bank 
regulatory agency to maintain the capital of WEX Bank will be assumed by the bankruptcy trustee and entitled to priority of 
payment. 

Restrictions on Ownership of WEX Inc. Common Stock 

WEX Bank, and therefore the Company, is subject to bank regulations that impose requirements on entities that might 
control WEX Bank through control of the Company. These requirements are discussed in Item 1A under the heading “If any entity 
controls 10 percent or more of our common stock and such entity has caused a violation of applicable banking laws by its failure 
to obtain any required approvals prior to acquiring that common stock, we have the power to, and may be required to, restrict such 
entity’s ability to vote shares held by it.” 

Healthcare Regulation

The federal and state governments in the U.S. continue to enact and consider many broad-based legislative and regulatory 
proposals that could materially impact various aspects of our health-related business.   The plans that our partners administer 
feature consumer accounts that pay for out-of-pocket expenses incurred by employees and qualified dependents.  These accounts 
include Consumer-Directed Health ("CDH") accounts such as Health Savings Accounts, Flexible Spending Accounts, and Health 
Reimbursement Arrangements (commonly referred to as HSAs, FSAs and HRAs, respectively), as well as wellness incentives, 
commuter benefits, and other account-based arrangements.  Most of these accounts are tax-advantaged under the appropriate law. 

15

 
 
 
 
 
 
Table of Contents

Employers are continuing to use CDH approaches to manage the rate of increase in healthcare expenditures and to enable 
employees to make decisions about the use of their healthcare savings.  CDH programs provide consumers with visibility of and 
control over payment for healthcare expenses.

The products that WEX Health's software and payment solutions support are subject to various state and federal laws, 
including the Affordable Care Act, and regulations promulgated by the Internal Revenue Service, the Department of Health and 
Human Services, the Department of Labor, and the Consumer Financial Protection Bureau.  As such, changes in the status of tax-
advantaged CDH accounts could affect the attractiveness of these products.

In addition to tax-related regulation, the Patient Protection and Affordable Care Act and the Health Care and Education 
Reconciliation Act (collectively referred to as “Health Care Reform”) mandated broad changes affecting insured and self-insured 
health benefit plans that impact our current business model, including our relationship with current and future customers, producers 
and health care providers, products, services, processes and technology. Health Care Reform left many details to be established 
through regulations. While federal agencies have published proposed and final regulations with respect to most provisions, some 
issues remain uncertain. The 2017 Tax Cuts and Jobs Act repealed certain provisions of Health Care Reform, including reducing 
to zero the tax penalty for going without Health Care Reform-compliant healthcare coverage. The current U.S. Administration and 
Congress  have  signaled  their  intent  to  significantly  modify  or  completely  repeal  Health  Care  Reform  and  the  associated 
implementing regulations. It is unclear what, if any, additional measures may be taken in this regard. Accordingly, there may be 
an extended period of uncertainty and unpredictability in the U.S. health care market, which may materially affect the availability 
and cost of health coverage, the viability of health care providers and health benefit plans, the proportion of persons in the U.S. 
who have health insurance; the distribution between privately funded and government funded health insurance; and the future 
demand for, and profitability of, the offerings of our health-related business under our current business model.

In connection with the processing of data, we frequently undertake or are subject to specific compliance obligations under 
privacy and data security-related laws, including the Health Insurance Portability and Accountability Act of 1996, or HIPAA, the 
Gramm-Leach-Bliley Act, and similar state and federal laws governing the collection, use, protection and disclosure of nonpublic 
personally identifiable information, including individually identifiable health information.

HIPAA and its implementing regulations, as amended by the Health Information Technology for Economic and Clinical 
Health Act, or the HITECH Act, impose requirements relating to the privacy, security and transmission of individually identifiable 
health information. Among other things, HIPAA, as amended by the HITECH Act, and its implementing regulations, subjects us 
to  regulations  and  contractual  obligations  that  impose  privacy  and  security  standards  and  breach  notification  and  reporting 
requirements. 

In addition to tax, federal data privacy, security laws and regulations, we are subject to state laws governing confidentiality 
and security of personally identifiable information and additional state-imposed breach notification and reporting requirements. 

Regulation - Foreign

The conduct of our businesses and the use of our products and services outside the U.S., are subject to various foreign 
laws and regulations administered by government entities and agencies in the countries and territories where we operate. Below 
is a summary of material applicable laws and regulations in the jurisdictions around the world in which we do business.

Asia-Pacific

Australia

The Company’s Australian operations are subject to laws and regulations of the Commonwealth of Australia governing 
banking and payment systems, financial services, credit products and money laundering. Because none of WEX Australia, WEX 
Fuel Cards Australia or WEX Prepaid Cards Australia holds an Australian Financial Services License or credit license or is an 
authorized deposit-taking institution, they operate within a framework of regulatory relief and exemptions afforded them on the 
basis  that  they  satisfy  the  requisite  conditions.   The Australian  operations  are  also  subject  to  the  Privacy Act  (1988)  and  the 
Australian Privacy Principles.

Asia, including Singapore

The Company's operations in Asia are subject to the operation of the laws and regulation of the countries in which we 
operate, including laws with regards to banking and payment systems, financial services, money laundering and data protection.

Europe

The Company’s European operations are subject to laws and regulations of the European Union and the countries in 
which we operate including, among others, those governing payment services, data protection, including General Data Protection 
Regulation (commonly referred to as "GDPR"), and information security, consumer credit and anti-money laundering. 

Brazil 

The Company’s Brazilian operations are subject to laws and regulations of the Brazilian government, in particular the 
Central Bank of Brazil. Brazil’s labor systems are governed by the Consolidation of Brazilian Labor Laws. Brazil is a signatory 
of the World Trade Organization’s Trade-Related Aspects of Intellectual Property Rights agreement. This agreement establishes 
a minimum protection standard to property rights and requires signatory countries to review and adapt national laws that meet that 
standard.

ITEM 1A. RISK FACTORS

The risks and uncertainties described below are not the only risks and uncertainties that we face. Additional risks 
and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. 
If any of those risks actually occurs, our business, financial condition, results of operations and cash flows could suffer. The 
risks and uncertainties discussed below also include forward-looking statements and our actual results may differ materially 
from those discussed in these forward-looking statements.

Risks Relating to Our Company

A significant portion of our revenues are related to the dollar amount of fuel purchased by our customers, and, as a 
result, volatility in fuel prices could have an adverse effect on our revenues.

Our customers in our Fleet Solutions segment primarily purchase fuel. Accordingly, a significant part of our 

revenue is dependent on fuel prices, which are prone to volatility.  As of December 31, 2017, management estimates that 
approximately 21 percent of our total revenues result from fees paid to us by fuel providers based on a negotiated 
percentage of the purchase price of fuel purchased by our customers. We estimate that during 2017, each one cent decline in 
average domestic fuel prices below average actual prices would result in approximately a $1.2 million decline in 2017 
revenue. Therefore, extended declines in the price of fuel would have a material adverse effect on our total revenues. In the 
fourth quarter of 2014, we suspended our fuel price hedging program and as of the second quarter of 2016, we no longer had 
any remaining fuel hedging derivatives outstanding.  As a result, we are exposed to the full impact of fuel price declines and 
our net income is exposed to fuel price volatility unless and until a fuel price hedging program is reinstated.  If fuel prices 
decline, the lack of a hedge will negatively impact our revenue and income.

Fuel prices are dependent on many factors, all of which are beyond our control. These factors include, among 

others: 

• 

• 

• 

• 

• 

• 

• 

supply and demand for oil and gas, and expectations regarding supply and demand;

speculative trading;

actions by major oil exporting nations;

level of U.S. oil production;

advances in oil production technologies;

political conditions in other oil-producing, gas-producing or supply-route countries, including revolution, 
insurgency, terrorism or war;

refinery capacity;

•  weather;

• 

• 

• 

• 

• 

• 

the prices of foreign exports and the availability of alternate fuel sources;

value of the U.S. dollar versus other major currencies;

actions by members of Organization of Petroleum Exporting Countries and other major oil-producing 
nations;

implementation of fuel efficiency standards and the adoption by fleet customers of vehicles with greater 

fuel efficiency or alternative fuel sources;

general worldwide economic conditions; and

governmental regulations, taxes and tariffs.

Another component of our revenue stream is the late fees that our customers pay on past due balances.  As a result, 
a decrease in the price of fuel leads to a decline in the amount of late fees we earn from customers who fail to pay us timely. 

A portion of our revenue in Europe is derived from the difference between the negotiated price of the fuel from the 
supplier and the price charged to the fleet customer. As a result, a contraction in these differences would reduce 
revenues and could adversely affect our operating results.

Revenue from our European Fleet business is derived from transactions where our revenue is tied to the difference 
between the negotiated price of the fuel from the supplier and the price charged to the fleet customer. The merchant’s cost of 
fuel is dependent on several factors including, among others, the factors described above affecting fuel prices. We 
experience fuel-price related revenue contraction when the merchant’s cost of fuel increases at a faster rate than the fuel 

18

 
 
 
 
 
Table of Contents

price we charge to our fleet customers, or the fuel-price we charge to our fleet customers decreases at a faster rate than the 
merchant’s cost of fuel. Accordingly, we generate less revenue, which could adversely affect our operating results.

Changes in interchange fees could decrease our revenue.

A portion of our revenue is generated by network processing fees charged to merchants, known as interchange fees, 
associated with transactions processed using our cards. Interchange fee amounts associated with cards are affected by a number 
of factors, including regulatory limits and fee changes. In addition, interchange fees are the subject of intense legal and regulatory 
scrutiny and competitive pressures in the electronic payments industry.  For example, the Durbin Amendment to the Dodd-
Frank Act, which serves to limit interchange fees may restrict or otherwise impact the way we do business or limit our ability 
to charge certain fees to customers. The Consumer Financial Protection Bureau, or the CFPB, is also engaged in rulemaking 
and regulation of the payments industry, in particular with respect to prepaid cards. On January 25, 2018, the CFPB issued a 
final rule amending several aspects of its prepaid accounts rule adopted in October 2016 and delayed the overall effective date 
for such prepaid accounts rule to April 1, 2019. The extensive nature of these regulations and the implementation dates for this 
additional rulemaking may result in additional compliance obligations and expense for our business and our customers. These 
factors could result in lower interchange fees generally in the future. Temporary or permanent decreases in the interchange 
fees associated with our card transactions, could adversely affect our business and operating results. 

If we fail to adequately assess and monitor credit risks posed by our customers, we could experience an increase in 
credit loss.

We are subject to credit risk posed by our customers, many of which are small-to mid-sized businesses. Because we 

often fund a customer's entire receivable while our revenue is generated from only a small percentage of that amount, our 
risk of loss is amplified by the customer's failure to pay.  We use various formulas and models to screen potential customers 
and establish appropriate credit limits, but these formulas and models cannot eliminate all potential credit risks and may not 
prevent us from approving applications that are fraudulently completed. Moreover, businesses that are good credit risks at 
the time of application may deteriorate over time and we may fail to detect such changes. In addition, changes to our 
policies on the types and profiles of businesses to which we extend credit could also have an adverse impact on our credit 
losses. In times of economic slowdown, the number of our customers who default on payments owed to us tends to increase. 
If we fail to adequately manage our credit risks, our provision for credit losses on the income statement could be 
significantly higher. 

We may incur substantial losses due to fraudulent use of our payment cards, payment systems or vouchers.

Under certain circumstances, we may bear the risk of substantial losses due to fraudulent use of our payment cards 

or payment systems.  We are also subject to risk from fraudulent acts of employees or contractors.  Although we maintain 
insurance for certain types of losses, the coverage may be insufficient or limited and may not fully protect against those 
losses. Additionally, criminals use sophisticated illegal activities to target us, including "skimming", counterfeit cards and 
accounts, and identity theft. A single, significant incident or a series of incidents of fraud or theft could lead to, among other 
things, some or all of the following:

• 
• 
• 
• 
• 
• 
• 
• 

increased overall level of fraud; 
direct financial losses as a result of fraudulent activity;
reputational harm; 
decreased desirability of our services; 
greater regulation;
increased compliance costs; 
imposition of regulatory sanctions; or
significant monetary fines.

All of the above could have a material adverse effect on our operations, business success, financial condition and 

results of operations. Our bad debt expense, inclusive of fraud losses, was $61.1 million in 2017 compared to $33.3 million 
in 2016.

Fluctuations in foreign currency exchange rates could affect our financial results.

We earn revenues, pay expenses, own assets and incur liabilities in countries using currencies other than the U.S. 

dollar. Such currencies include, but are not limited to, the Australian dollar, the Canadian dollar, the Euro, British Pound 
sterling, New Zealand dollar and Brazilian Real. Because our consolidated financial statements are presented in U.S. dollars, 
we must translate revenues, income and expenses, as well as assets and liabilities, into U.S. dollars at exchange rates in 
19

 
 
 
 
 
 
Table of Contents

effect during or at the end of each reporting period. Realized and unrealized gains and losses on foreign currency 
transactions as well as the re-measurement of our cash, receivable and payable balances that are denominated in foreign 
currencies, are recorded directly in the consolidated statements of income. In addition, gains and losses associated with the 
Company's foreign currency exchange derivatives are recorded on the consolidated statements of income.

Therefore, increases or decreases in the value of the U.S. dollar against other major currencies that we use to 

conduct our business will affect our revenues, operating income and the value of balance sheet items denominated in those 
currencies. Fluctuations in foreign currency exchange rates, particularly fluctuations in the U.S. dollar against other 
currencies, may materially affect our financial results.

Our exposure to counterparty risk could create an adverse effect on our financial condition.

We engage in a number of transactions where counterparty risk is a relevant factor, including transactions with 

customers, derivatives counterparties and those businesses we work with to provide services, among others. These risks are 
dependent upon market conditions and also the real and perceived viability of the counterparty. The failure or perceived 
weakness of any of our counterparties has the potential to expose us to risk of loss in certain situations. Certain contracts 
and arrangements that we enter into with counterparties may provide us with indemnification clauses to protect us from 
financial loss. If the counterparty fails to, or is unable to fulfill these indemnification clauses, we may incur losses as well as 
harm to our reputation.

We have substantial indebtedness, which may materially and adversely affect our financial flexibility and our ability 
to meet our debt service obligations. 

Our 2016 Credit Agreement, as amended on January 17, 2018, provides for a tranche A term loan facility in an 

amount equal to $455 million that matures on July 1, 2021 (of which $421 million remained outstanding at the time of the 
amendment), a tranche B term loan facility in an amount equal to $1,335 million that matures on July 1, 2023 and a $570 
million secured revolving credit facility, with a $250 million sublimit for letters of credit and a $20 million sublimit for 
swingline loans, that terminates on July 1, 2021. Prior to maturity, amounts under the credit facility will be reduced by 
mandatory amortization payments and may be reduced by the mandatory prepayment of our tranche B term loan facility out 
of a certain portion of our excess cash or by optional prepayments. In addition to the 2016 Credit Agreement, our 
indebtedness consists of our 4.750 percent senior notes in the principal amount of $400 million due 2023 (the “Notes”), 
deposits issued by WEX Bank and other liabilities outstanding. Our indebtedness could, among other things: 

•  require us to dedicate a substantial portion of our cash flow to repaying our indebtedness, thus reducing the amount

of funds available for other general corporate purposes;

•  limit our ability to borrow additional funds necessary for working capital, capital expenditures or other general

corporate purposes;

•  increase our vulnerability to adverse general economic or industry conditions; and
•  limit our flexibility in planning for, or reacting to changes in, our business.

There can be no assurance that we will be able to meet our indebtedness obligations, including any of our 
obligations under the Notes. In addition, we may need to incur substantial additional indebtedness in the future to fund our 
operations or certain strategic objectives. However, we may not be able to obtain the additional financing necessary for 
these purposes.

In addition, under the 2016 Credit Agreement, unless otherwise agreed by the requisite lenders under the revolving 

credit facility, we are required to remain in compliance with a consolidated EBITDA to consolidated interest charge ratio, 
measured quarterly, of no less than 3.25 to 1.00; and a consolidated funded indebtedness (excluding up to $350 million of 
consolidated funded indebtedness due to permitted securitization transactions and excluding the amount of consolidated 
funded indebtedness constituting the non-recourse portion of permitted factoring transactions) to consolidated EBITDA 
ratio,measured quarterly, of no more than 5.00 to 1.00, which ratio shall step down to 4.50 to 1.00 at December 31, 2018 
and 4.00 to 1.00 at December 31, 2019.  In addition, in the event of an acquisition meeting certain specified criteria, the 
consolidated leverage ratio shall be permanently increased by 0.50:1.00.  The 2016 Credit Agreement also contains various 
affirmative and negative covenants that, subject to certain customary exceptions, restrict our ability to, among other things, 
create liens over our property, incur additional indebtedness, enter into sale and lease-back transactions, make loans, 
advances or other investments, make non-ordinary course asset sales, declare or pay dividends or make other distributions 
with respect to equity interests, change the nature of our business, enter into certain agreements which restrict our ability to 
pay dividends or other distributions or create liens on our property, transact business with affiliates and/or merge or 

20

 
 
 
 
 
Table of Contents

consolidate with any other person. Our ability to comply with these provisions may be affected by events beyond our 
control. Failure to comply with the financial covenants or any other non-financial or restrictive covenant in our 2016 Credit 
Agreement could create a default. Upon a default, our lenders could accelerate the indebtedness under the facilities (except 
only the requisite lenders under the revolving credit facility and the tranche A term loan facility may accelerate the revolving 
credit facility due to a breach of the financial covenants), foreclose against their collateral or seek other remedies, which 
could trigger a default under the Notes and would jeopardize our ability to continue our current operations.

Despite our substantial indebtedness, we may still be able to incur more debt, intensifying the risks described above.

Subject to restrictions in our 2016 Credit Agreement and the Notes, we may incur additional indebtedness, which 

could increase the risks associated with our already substantial indebtedness. Subject to certain limitations, including 
compliance with the covenants in our 2016 Credit Agreement, we have the ability to borrow additional funds under our 
2016 Credit Agreement.

This indebtedness could have the effect, among other things, of reducing our flexibility to respond to changing 

business and economic conditions and increasing interest expense.

Moreover, we may be required to raise substantial additional financing to fund working capital, capital 

expenditures, acquisitions or other general corporate requirements. Our ability to arrange additional financing or refinancing 
will depend on, among other factors, our financial position and performance, as well as prevailing market conditions and 
other factors beyond our control. There can be no assurance that we will be able to obtain additional financing or 
refinancing on terms acceptable to us or at all.

Volatility in the financial markets may negatively impact our ability to access credit and the terms at which we would 
access such credit. 

Adverse conditions in the credit market may limit our ability to access credit at a time when we would like or need 

to do so. Our senior secured revolving credit facility under the 2016 Credit Agreement expires in July 2021 when the 
outstanding balance of the revolving credit facility and the tranche A term loan will be due, and in 2023 the tranche B term 
loan and the Notes will be due. Any limitation on the availability of funds or credit facilities could have an impact on our 
ability to refinance the maturing debt or react to changing economic and business conditions which could adversely impact 
us.

Volatility in the financial markets may negatively impact WEX Bank’s ability to attract and retain deposits.

Adverse conditions in the credit market may limit WEX Bank’s ability to attract deposits at a time when it would 

like or need to do so. A significant credit ratings downgrade, material capital market disruptions, significant withdrawals by 
depositors at WEX Bank, or adverse changes to its industrial bank charter could impact our ability to maintain adequate 
liquidity and impact our ability to provide competitive offerings to our customers. Any limitation of availability of deposits 
could have an impact on our ability to finance our U.S. accounts receivable which would adversely impact us.

Our industrial bank subsidiary is subject to funding risks associated with its reliance on brokered deposits.

Under applicable regulations, if WEX Bank were no longer “well capitalized,” it would not be able to accept 
brokered deposits without the approval of the FDIC. WEX Bank’s inability to accept brokered deposits, or a loss of a 
significant amount of its brokered deposits, could adversely affect our liquidity. Additionally, such circumstances could 
require it to raise deposit rates in an attempt to attract new deposits, or to obtain funds through other sources at higher rates, 
which would adversely affect our results of operations.

To service our indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on 
many factors beyond our control.

Our ability to make payments on and to refinance our indebtedness, and to fund capital expenditures, acquisitions 

and research and development efforts will depend on our ability to generate cash. This, to a certain extent, is subject to 
economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

We have substantial indebtedness, and may incur additional indebtedness, which could lead to increased interest 

expense and could increases the amount of cash flows required to fund interest expense associated with our indebtedness. In 
addition, certain obligations under the 2016 Credit Agreement bear interest at variable interest rates. We currently maintain 
five forward-fixed interest rate swap agreements which are intended to fix the future interest payments associated with 
$1,300 million of our variable-rate borrowings; however, those swap agreements expire at various points prior to the 

21

 
 
 
 
 
 
 
 
Table of Contents

expiration of the 2016 Credit Agreement.  In addition, interest rate increases still could result in larger debt service 
requirements. Such an increase in our debt service obligations would adversely affect our cash flows. 

We cannot assure you that our business will generate sufficient cash flows from operations, that anticipated cost 
savings and operating improvements will be realized on schedule or at all, that future borrowings will be available to us 
under our 2016 Credit Agreement or any subsequent credit agreement, or that we can obtain alternative financing proceeds 
in an amount sufficient to enable us to pay our indebtedness, including the Notes, or to fund our other liquidity needs. We 
may need to refinance all or a portion of our indebtedness, including the Notes, at or before maturity. We cannot assure you 
that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all.

The debt service obligations under our 2016 Credit Agreement could also reduce funds available for working 

capital, capital expenditures, acquisitions and other general corporate purposes and may create competitive disadvantages 
relative to other companies with lower debt levels. The 2016 Credit Agreement was used in part to finance the acquisition of 
EFS.  If we do not achieve the expected benefits and cost savings from the acquisition, or if the financial performance of the 
combined company does not meet current expectations, then our ability to service our indebtedness may be adversely 
impacted.

In an environment of increasing interest rates, interest expense on the variable rate portion of our borrowings would 
increase and we may not be able to replace our maturing debt with new debt that carries the same interest rates. We 
may be adversely affected by significant changes in the brokered deposit market. 

Our industrial bank subsidiary, WEX Bank, uses collectively brokered deposits, including certificates of deposit 

and interest-bearing money-market deposits, to finance payments to major oil companies. Certificates of deposit carry fixed 
interest rates from issuance to maturity, which vary and are relatively short term in duration. The interest-bearing money 
market deposits carry variable rates. Upon maturity, the deposits will likely be replaced by issuing new deposits to the extent 
that they are needed. In a rising interest rate environment, WEX Bank would not be able to replace maturing deposits with 
deposits that carry the same or lower interest rates. Therefore, rising interest rates would result in reduced net income to the 
extent that certificates of deposit and money market deposits mature and are replaced. At December 31, 2017, WEX Bank 
had outstanding $630.9 million in certificates of deposit maturing within one year, $306.9 million in certificates of deposit 
maturing between one and three years, and $285.9 million in interest-bearing money market deposits, for an aggregate 
exposure of $1,223.7 million in brokered deposits at WEX Bank. 

Additionally, under our 2016 Credit Agreement and Notes, we had $2,139.4 million of fixed and variable interest 

rate indebtedness outstanding at December 31, 2017, consisting of $400.0 million of borrowings under our bond facility at a 
fixed rate of 4.750 percent and $1,300 million of borrowings under our 2016 Credit Agreement that bore interest at floating 
rates, subject to the partial hedging arrangement described above. An increase in interest rates would increase the cost of 
borrowing under our 2016 Credit Agreement. 

Our 2016 Credit Agreement uses LIBOR as a reference rate for our term loans and revolving credit facility, such 

that the interest due pursuant to a such loans may be calculated using LIBOR (subject to a stated minimum value).  On July 
27, 2017, the United Kingdom’s Financial Conduct Authority, which regulates LIBOR, announced that it intends to phase 
out LIBOR by the end of 2021. It is unclear if at that time LIBOR will cease to exist or if new methods of calculating 
LIBOR will be established such that it continues to exist after 2021. The future of LIBOR at this time is uncertain. If the 
method for calculation of LIBOR changes, if LIBOR is no longer available or if lenders have increased costs due to changes 
in LIBOR, we may suffer from potential increases in interest rates on our floating debt rate. Further, we may need to 
renegotiate our 2016 Credit Agreement and the loans that utilize LIBOR as a factor in determining the interest rate to 
replace LIBOR with the new standard that is established.

 The Dodd-Frank Act may have a significant impact on our business, results of operation and financial condition.

On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank 

Act, was enacted into law. The Dodd-Frank Act, among other things, when fully implemented, will result in substantial 
changes in the regulation of derivatives and capital market activities. The impact of the Dodd-Frank Act is difficult to assess 
because many provisions are being phased in over time and because the current Presidential administration has indicated it 
may make or propose changes to provisions of the Dodd-Frank Act. In particular, the Dodd-Frank Act establishes federal 
oversight and regulation of the over-the-counter derivatives market and entities that participate in that market.  The rules, if 
enacted in their proposed form, may require us to change to any fuel price, currency and interest rate hedging practices we 
may then use to comply with new regulatory requirements. Potential changes include clearing and execution methodology 
of our derivatives transactions. The Dodd-Frank Act also requires many counterparties to derivatives instruments to spin off 
some of their derivatives activities to a separate entity. These new entities may not be as creditworthy as the current 
counterparty. Presently, we cannot assess the capital or margin requirements which might apply to our over-the-counter 
22

 
 
 
 
 
 
Table of Contents

transactions. Once implemented, these changes could result in increased transaction costs. In summary, the Dodd-Frank Act 
and any new regulations could increase the cost of derivative contracts or modify the way in which we conduct those 
transactions. Additionally, we are required to pay to the lenders under the 2016 Credit Agreement, any increased costs 
associated with the Dodd-Frank Act and other changes in laws, rules or regulations, subject to the terms of the 2016 Credit 
Agreement.

The Dodd-Frank Act also created the CFPB, to regulate the offering of consumer financial products or services 
under the federal consumer financial laws. The CFPB assumed rulemaking authority under the existing federal consumer 
financial protection laws, and enforces those laws against and examines certain non-depository institutions and insured 
depository institutions with total assets greater than $10 billion and their affiliates. In addition, the CFPB was granted 
general authority to prevent covered persons or service providers from committing or engaging in unfair, deceptive or 
abusive acts or practices under federal law in connection with any transaction with a consumer for a consumer financial 
product or service, or the offering of a consumer financial product or service. The CFPB also has broad rulemaking 
authority for a wide range of consumer protection laws. It is unclear what changes will be promulgated by the CFPB and 
what effect, if any, such changes would have on our business and operations.

As required under the Dodd-Frank Act, the Government Accountability Office issued its study on the implications 
of any elimination of the exemption to the definition of “bank” for industrial banks under the Bank Holding Company Act. 
The study did not make a recommendation regarding the elimination of this exemption. However, if this exemption were 
eliminated without any grandfathering or accommodations for existing institutions, we could be required to become a bank 
holding company which could require us to either cease certain activities or divest WEX Bank.

The current U.S. Administration and Congress have signaled their intent to significantly or completely repeal the 
Dodd-Frank Act and the associated implementing regulations, and it is unclear what, if any, measures may be implemented 
to replace it.  Accordingly, there may be an extended period of uncertainty and unpredictability regarding the provisions of 
federal law and regulations that affect our business and operations.   

The Dodd-Frank Act and any related legislation or regulations, or any repeal or replacement of such legislation or 

regulations, may have a material impact on our business, results of operations and financial condition. The full impact of the 
Dodd-Frank Act will not be known until all of the regulations implementing the statute are adopted and implemented. 
However, compliance with these new laws and regulations may require us to make changes to our business, and, there is a 
significant possibility that the Dodd-Frank Act will, at a minimum, result in increased regulatory burden and compliance 
costs.  We may be required to invest significant management time and resources to address the various provisions of the 
Dodd-Frank Act and the numerous regulations that are required to be issued under it, or to address the changed business 
environment resulting from a repeal of all or part of the Dodd Frank Act and any related legislation or regulation.

Decreased demand for fuel and other vehicle products and services could harm our business and results of 
operations.

Demand for fuel and other vehicle products and services may be reduced by factors that are beyond our control, 

such as the implementation of fuel efficiency standards and the development by vehicle manufacturers and adoption by our 
fleet customers of vehicles with greater fuel efficiency or alternative fuel sources. To the extent that our customers require 
less fuel, that decline in purchase volume could reduce our revenues, limiting our profitability and preventing us from taking 
on other initiatives.

Our business is dependent on several key strategic relationships, the loss of which could adversely affect our results 
of operations.

Revenue we received from services we provided to our top five customers and strategic relationships accounted for 

approximately 10 percent of our total revenues in 2017. Accordingly, we are dependent on maintaining our strategic 
relationships and our results of operations would be lower in the event that any of these relationships ceases to exist. 
Likewise, we have agreements with the major oil companies, fuel retailers and truck stop merchants whose locations accept 
our payment processing services. The termination of any of these agreements would reduce the number of locations where 
our payment processing services are accepted; therefore, we could lose our competitive advantage and our operating results 
could be adversely affected. While we regularly monitor these relationships, there can be no guarantee that we will be able 
to maintain them in the future.

We may never realize the anticipated benefits of acquisitions we have completed or may undertake.

We have acquired and may attempt to acquire businesses, technologies, services, products or licenses in 

technologies that we believe are a strategic fit with our business. The process of integrating and operating any acquired 

23

 
 
 
 
 
 
 
Table of Contents

business, technology, service or product may result in unforeseen redundancies, operating difficulties, and expenditures and 
may divert significant management attention from our ongoing business operations. As a result, we may incur a variety of 
costs in connection with acquisitions and may never realize the anticipated benefits. 

We are exposed to risks associated with operations outside of the United States, which could harm both our U.S. and 
international operations.

We conduct operations in North America, South America, Asia Pacific and Europe. As part of our business strategy 

and growth plan, we plan to further expand internationally. Expansion of our international operations could impose 
substantial burdens on our resources, divert management’s attention from U.S. operations and otherwise harm our business. 
In addition, there are many barriers to competing successfully in the international market, including: 

• 

• 

• 

• 

• 

• 

• 

• 

• 

fluctuation in foreign currencies;

changes in the relations between the United States and foreign countries;

actions of foreign or United States governmental authorities affecting trade and foreign investment;

increased infrastructure costs including complex legal, tax, accounting and information technology laws and 
treaties;

interpretation and application of local laws and regulations including, among others, those impacting anti-money 
laundering, bribery, financial transaction reporting and positive balance or prepaid cards;

enforceability of intellectual property and contract rights;

potentially adverse tax consequences due to, but not limited to, the repatriation of cash and negative consequences 
from changes in or interpretations of tax laws

competitive pressure on products and services from companies based outside the U.S. that can leverage lower costs 
of operations; 

the United Kingdom's decision in a June 23, 2016 referendum to leave the European Union (EU) (commonly 
referred to as “Brexit”); and

• 

local labor conditions and regulations.

We cannot assure you that our investments outside the United States will produce desired levels of revenue or 

costs, or that one or more of the factors listed above will not harm our business.

New laws, regulations and enforcement activities could negatively impact our business and the markets we presently 
operate in or could limit our expansion opportunities. 

Our operations are subject to substantial regulation both domestically and internationally. There are often new 

regulatory efforts which could result in significant constraints and may impact our operations. These existing and emerging 
regulations can make the expansion of our business very difficult and negatively impact our revenue. Among the regulations 
that impact us or could impact us are those governing: interchange rates; interest rate and fee restrictions; credit access and 
disclosure requirements; collection and pricing requirements; compliance obligations; data security and data breach 
requirements; identity theft avoidance programs; health care mandates; and anti-money laundering compliance programs. 
We also often must obtain permission to conduct business in new locations from government regulators. Changes to these 
regulations, including expansion of consumer-oriented regulation to business-to-business transactions, could negatively 
impact our operations, financial condition and results of operations and could further increase our compliance costs and 
limit our ability to expand to new markets.

We also conduct business with other highly regulated businesses such as banks, payment card issuers, and health 

insurance providers. These industries are subject to significant potential reforms that could negatively affect these 
businesses, their ability to maintain or expand their products and services, and the costs associated with doing so. These 
developments could also negatively impact our business. 

24

 
 
 
 
Table of Contents

Laws or regulations developed in one jurisdiction or for one product could result in new laws or regulations in other 
jurisdictions or for other products.

Regulators often monitor other approaches to the governance of the payment industry. As a result, a law or 
regulation enacted in one jurisdiction could result in similar developments in another. In addition, law and regulation 
involving one product could influence the extension of regulations to other product offerings. 

The expansion of certain regulations could negatively impact our business in other geographies or for other 

products. Rules and regulations concerning interchange and business operations regulations, for example, may differ from 
country to country which adds complexity and expense to our operations. 

These varying and increasingly complex regulations could limit our ability to globalize our products and could 

significantly and adversely affect our business, financial condition and results of operations.

Regulations and industry standards intended to protect or limit access to personal information could adversely affect 
our ability to effectively provide our services.

Governmental bodies in the United States and abroad have adopted, or are considering the adoption of, laws and 
regulations restricting the transfer of, and requiring safeguarding of, non-public personal information. For example, in the 
United States, all financial institutions must undertake certain steps to ensure the privacy and security of consumer financial 
information. In Europe, the adoption of General Data Protection Regulation (commonly referred to as GDPR) also requires 
additional privacy protections.  In connection with providing services to our clients, we are required by regulations and 
arrangements with payment networks and certain clients to provide assurances regarding the confidentiality and security of 
non-public consumer information. These arrangements require periodic audits by independent companies regarding our 
compliance with industry standards such as payment card industry, or PCI, standards and also allow for similar audits 
regarding best practices established by regulatory guidelines. The compliance standards relate to our infrastructure and 
operational procedures designed to safeguard the confidentiality and security of non-public consumer personal information 
received from our customers. Our ability to maintain compliance with these standards and satisfy these audits will affect our 
ability to attract and maintain business in the future. If we fail to comply with these regulations, we could be exposed to 
suits for breach of contract or to governmental proceedings. In addition, our client relationships and reputation could be 
harmed, and we could be inhibited in our ability to obtain new clients. If more restrictive privacy laws or rules are adopted 
by authorities in the future on the federal or state level, our compliance costs may increase, our opportunities for growth 
may be curtailed by our compliance capabilities or reputational harm and our potential liability for security breaches may 
increase, all of which could have a material adverse effect on our business, financial condition and results of operations.

Changes in our tax rates, the adoption of new U.S. or international tax legislation or exposure to additional tax 
liabilities could affect our future results.

We are subject to taxes in the U.S. and numerous foreign jurisdictions. Our future effective tax rates could be 
affected by changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred 
tax assets and liabilities, or changes in tax laws or their interpretation. Any of these changes could have a material adverse 
effect on our profitability. We are also subject to the examination of our income tax returns by the Internal Revenue Service 
and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to 
determine the adequacy of our provision for taxes. There can be no assurance that the outcomes from these examinations 
will not materially adversely affect our financial condition and operating results.

On December 22, 2017, President Trump signed into law new legislation that significantly revised the Internal 

Revenue Code of 1986, as amended. The newly enacted federal income tax law, among other things, contains significant 
changes to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 
21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings (except for certain small businesses), 
limitation of the deduction for net operating losses to 80% of current year taxable income and elimination of net operating 
loss carrybacks, in each case, for losses arising in taxable years beginning after December 31, 2017 (though any such net 
operating losses may be carried forward indefinitely), one time taxation of offshore earnings at reduced rates regardless of 
whether they are repatriated, elimination of U.S. tax on foreign earnings (subject to certain important exceptions), 
immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying 
or repealing many business deductions and credits. Notwithstanding the reduction in the corporate income tax rate, the 
overall impact of the new federal tax law is uncertain and our business and financial condition could be adversely 
affected. In addition, it is uncertain how various states will respond to the newly enacted federal tax law. The impact of this 
tax reform on holders of our common stock is also uncertain and could be adverse. We urge our stockholders to consult with 
their legal and tax advisors with respect to this legislation and the potential tax consequences of investing in or holding our 
common stock.

The healthcare industry changes often and technology-enabled services used by consumers are relatively new and 
unproven.

The market for technology-enabled services for healthcare consumers changes rapidly and new products and 

services are consistently being introduced. Opportunities to gain market share are challenging due to the significant 
resources of our existing and potential competitors. It is uncertain whether or how fast this market will continue to grow. In 
order to remain competitive, we are continually involved in a number of projects to develop new services or compete with 
these new market entrants, including the development of mobile versions of our proprietary technology platform. These 
projects carry risks, such as cost overruns, delays in delivery, performance problems and lack of acceptance by our 
customers.

Based on our experience, consumers are still learning about health savings accounts, which are often referred to as 

HSAs, and other similar tax-advantaged healthcare savings arrangements. The willingness of consumers to increase their 
use of technology platforms to manage their healthcare saving and spending tax advantaged benefits will impact our 
operating results. 

We may incur impairment charges on goodwill or other intangible assets.

We account for goodwill in accordance with Financial Accounting Standards Board, which is often referred to as 

FASB, Accounting Standard Codification Topic 350, Intangibles—Goodwill and Other. Our reporting units and related 
indefinite-lived intangible assets are tested annually during the fourth fiscal quarter of each year in order to determine 
whether their carrying value exceeds their fair value. In addition, they are tested on an interim basis if an event occurs or 
circumstances change between annual tests that would more likely than not reduce their fair value below carrying value. If 
we determine the fair value of the goodwill or other indefinite-lived intangible assets is less than their carrying value as a 
result of the tests, an impairment loss is recognized. Any such write-down would adversely affect our results of operations.

Our goodwill resides in multiple reporting units. The profitability of individual reporting units may suffer 

periodically from downturns in customer demand and other factors, the high level of competition existing within our 
industry, and the level of overall economic activity. Individual reporting units may be relatively more impacted by these 
factors than the Company as a whole. As a result, demand for the services of one or more of the reporting units could 
decline which could adversely affect our operations and cash flow, and could result in an impairment of goodwill or 
intangible assets. As a result of our annual impairment analyses during the fourth quarter of fiscal 2017, we did not identify 
any impairment of goodwill and other indefinite-lived intangible assets. For all reporting units, we use a discounted cash 
flow model of the projected earnings of reporting units to determine the amount of goodwill impairment. While we currently 
believe that the fair value of all of our intangibles substantially exceeds carrying value and that those intangibles so 
classified will contribute indefinitely to the cash flows of the Company, materially different assumptions regarding future 
performance of our reporting units or the weighted-average cost of capital used in the valuations could result in impairment 
losses and/or additional amortization expense. 

If our industrial bank subsidiary fails to meet certain criteria, we may become subject to regulation under the Bank 
Holding Company Act, which could force us to divest WEX Bank or cease all of our non-banking activities and thus 
could have an adverse effect on our revenue and business or could create a default under our 2016 Credit Agreement.

WEX Bank meets the criteria for exemption of an industrial bank from the definition of “bank” under the Bank 
Holding Company Act. WEX Bank’s failure to qualify for this exemption would cause us to become subject to regulation 
under the Bank Holding Company Act. This would require us to divest WEX Bank or become a Bank Holding Company 
and to possibly cease certain non-banking activities which may be impermissible for a Bank Holding Company, and could 
create a default under our 2016 Credit Agreement. Failure to qualify for this exemption could thus have an adverse effect on 
our revenue and business.

The loss or suspension of the charter for our Utah industrial bank or changes in regulatory requirements could be 
disruptive to operations and increase costs.

The regulatory status of WEX Bank enables it to issue certificates of deposit, accept money market deposits and 

borrow on a federal funds rate basis from other banks. These funds are used to support our operations. WEX Bank operates 
under a uniform set of state lending laws, and its operations are subject to extensive state and federal regulation. WEX 
Bank, a Utah industrial bank incorporated in 1998, is an FDIC-insured depository institution. The bank’s primary regulators 
are the Utah DFI and the FDIC. Continued licensing and federal deposit insurance are subject to ongoing satisfaction of 
compliance and safety and soundness requirements. If WEX Bank were to lose its bank charter, we would either outsource 
our credit support activities or perform these activities ourselves, which would subject us to the credit laws of each 
individual state in which we conduct business. Furthermore, we could not be a MasterCard issuer and would have to work 

26

 
 
 
 
 
 
Table of Contents

with another financial institution to issue the product or sell the portfolio. Any such change would be disruptive to our 
operations and could result in significant incremental costs. In addition, changes in the bank regulatory environment, 
including the implementation of new or varying measures or interpretations by the State of Utah or the federal government, 
may significantly affect or restrict the manner in which we conduct business in the future or could create a default under our 
2016 Credit Agreement.

We are subject to extensive supervision and regulation that could restrict our activities and impose financial 
requirements or limitations on the conduct of our business and limit our ability to generate income.

We are subject to extensive federal and state regulation and supervision, including that of the FDIC, the CFPB, and 

the Utah DFI. Banking regulations are primarily intended to protect depositors’ funds, federal deposit insurance funds and 
the banking system as a whole, not shareholders or noteholders. These regulations affect our payment operations, capital 
structure, investment practices, dividend policy and growth, among other things. Failure to comply with laws, regulations or 
policies could result in sanctions by regulatory agencies, damages, civil money penalties or reputational damage, which 
could have a material adverse effect on our business, financial condition and results of operations. While we have policies 
and procedures designed to prevent any such violations, there can be no assurance that such violations will not occur. The 
U.S. Congress and federal regulatory agencies frequently revise banking and securities laws, regulations and policies. We 
cannot predict whether or in what form any other proposed regulations or statutes will be adopted or the extent to which our 
business may be affected by any new regulation or statute. Such changes could subject our business to additional costs, limit 
the types of financial services and products we may offer and increase the ability of non-banks to offer competing financial 
services and products, among other things.

Our industrial bank subsidiary is subject to regulatory capital requirements that may require us to make capital 
contributions to this subsidiary, and that may restrict the ability of the subsidiary to make cash available to us.

WEX Bank must maintain minimum amounts of regulatory capital. If WEX Bank does not meet these capital 

requirements, its regulators have broad discretion to institute a number of corrective actions that could have a direct material 
effect on our financial condition. WEX Bank, as an institution insured by the FDIC, must maintain certain capital ratios, 
paid-in capital minimums and adequate allowances for loan losses. Under the Dodd-Frank Act, we are also required to serve 
as a source of financial strength for WEX Bank. If WEX Bank were to fail to meet any of the capital requirements to which 
it is subject, or if required under Dodd-Frank’s source of strength requirements, we may be forced to provide WEX Bank 
with additional capital, which could impair our ability to service our indebtedness or may not be permitted under the terms 
of our 2016 Credit Agreement or Notes. To pay any dividend, WEX Bank must maintain adequate capital above regulatory 
guidelines. Accordingly, WEX Bank may be unable to make any of its cash or other assets available to us, including to 
service our indebtedness.

We are subject to limitations on transactions with our industrial bank subsidiary, which may limit our ability to 
engage in transactions with and obtain credit from our industrial bank.

Sections 23A and 23B of the FRA and the implementing regulations limit the extent to which we can borrow or 
otherwise obtain credit from or engage in other “covered transactions” with WEX Bank. “Covered transactions” include 
loans or extensions of credit, purchases of or investments in securities, purchases of assets, including assets subject to an 
agreement to repurchase, acceptance of securities as collateral for a loan or extension of credit, or the issuance of a 
guarantee, acceptance, or letter of credit. Although the applicable rules do not serve as an outright ban on engaging in 
“covered transactions,” they do limit the amount of covered transactions WEX Bank may have with any one affiliate and 
with all affiliates in the aggregate. The applicable rules also require that we engage in such transactions with WEX Bank 
only on terms and under circumstances that are substantially the same, or at least as favorable to WEX Bank, as those 
prevailing at the time for comparable transactions with nonaffiliated companies. Furthermore, with certain exceptions, each 
loan or extension of credit by WEX Bank to the Company or its other affiliates must be secured by collateral with a market 
value ranging from 100 percent to 130 percent of the amount of the loan or extension of credit, depending on the type of 
collateral. Accordingly, WEX Bank may be unable to provide credit or engage in transactions with us, including transactions 
intended to help us service our indebtedness.

If the technologies we use in operating our business and interacting with our customers fail, are unavailable, or do 
not operate to expectations, or we fail to successfully implement technology strategies and capabilities in connection 
with our outsourcing arrangements, our business and results of operation could be adversely impacted.

We utilize a combination of proprietary and third-party technologies to operate our business and interact with our 

customers, partners and suppliers, among others. This includes technology that we have developed, have contracted with 
others to develop, have outsourced to a single provider to operate or have obtained through third-parties by way of service 
agreements.  To the extent that our proprietary technology or a third-party providers’ technology does not work as agreed to 

27

 
 
 
 
Table of Contents

or as expected, or if we experience outages or unavailability resulting from their operations and the services they provide to 
us, our ability to efficiently and effectively deliver services could be adversely impacted and our business and results of 
operations could be adversely affected. Similarly, any failure by our customers or partners to access the technology that we 
develop internally could have an adverse effect on our business, results of operations and financial condition.  Although we 
make substantial investments in technology, there is no guarantee that it will function as intended once it is placed into 
operation. Lastly, given our reliance on technology, we regularly assess our technology plans, including both platforms and 
technology infrastructure. To the extent that we conclude that certain technologies should be retired, that existing platforms 
should be consolidated, or that we should change our technology strategies, we may be required to impair or accelerate 
depreciation on certain assets. Any of these potential changes or failures in our technology strategies may also divert 
management’s attention and have a material adverse effect on our business and results of operations.

Our business is regularly subject to cyberattacks and attempted security and privacy breaches and we may not be 
able to adequately protect our information systems, including the data we collect about our customers, which could 
subject us to liability and damage our reputation.

We collect and store data about our customers and their fleets, including bank account information and spending 
data. Our customers expect us to keep this information in our confidence. In certain instances, the information we collect 
includes social security numbers. As a result of applicable laws, we are required to take commercially reasonable measures 
to prevent and mitigate the impact of cyber-attack, as well as the unauthorized access, acquisition, release and use of 
“personally identifiable information," such as social security numbers. While social security numbers constitute a very small 
part of the data we keep, in the event of a security breach we would be required to determine the types of information 
compromised and determine corrective actions and next steps under applicable laws, which would require us to expend 
capital and other resources to address the security breach and protect against future breaches.  An increasing number of 
organizations, including large on-line and off-line merchants and businesses, large Internet companies, financial institutions, 
and government institutions, have disclosed breaches of their information security systems, some of which have involved 
sophisticated and highly targeted attacks, including on portions of their websites or infrastructure.  Like those companies, 
we too, are subject to regular and repeated attempts to breach our information security protections.

As outsourcing, specialization of functions, third-party digital services and technology innovation within the 

payments industry increase (including with respect to mobile technologies, tokenization, big data and cloud storage 
solutions), more third parties are involved in processing card transactions and there is a risk the confidentiality, integrity, 
privacy and/or security of data held by, or accessible to, third parties, including merchants that accept our cards, payment 
processors and our business partners, may be compromised, which could lead to unauthorized transactions on our cards and 
costs associated with responding to such an incident. In addition, high profile data breaches could change consumer 
behaviors, impact our ability to access data to make product offers and credit decisions and result in legislation and 
additional regulatory requirements.

The techniques used in attempts to obtain unauthorized, improper or illegal access to our systems, our data or our 
customers' data, to degrade service, or to sabotage our systems are constantly evolving, are difficult to detect quickly, and 
may not be recognized until after a successful penetration of our information security systems. Unauthorized parties attempt 
to gain access to our systems or facilities through various means, including, among others, targeting our systems or facilities 
or our third-party vendors or customers, or attempting to fraudulently induce our employees, partners, customers or others 
into disclosing user names, passwords, payment card information, or other sensitive information, which may in turn be used 
to access our information technology systems. Certain efforts may be state-sponsored and supported by significant financial 
and technological resources, making them even more difficult to detect. Like many companies, we are a target for such 
breaches and attacks. Although we have developed systems and processes that are designed to protect our data and customer 
data and to prevent data loss and other security breaches, and will continue to expend significant additional resources to 
bolster these protections, these security measures cannot provide absolute security. Our information technology and 
infrastructure may be vulnerable to successful cyberattacks or security breaches, and third parties may be able to access our 
customers’ personal or proprietary information and data that are stored on or accessible through those systems. 

Our security measures may also be breached due to employee error, malfeasance, system errors or vulnerabilities, 
or other irregularities. Any actual or perceived breach of our security could interrupt our operations; result in our systems or 
services being unavailable; result in improper disclosure of data; materially harm our reputation and brand; result in 
significant legal and financial exposure; lead to loss of customer confidence in, or decreased use of, our products and 
services; and, adversely affect our business and results of operations. Any breaches of network or data security at our 
partners, some of whom maintain information about our customers, or breaches of our customers' systems could have 
similar effects. In addition, our customers could have vulnerabilities on their own computer systems that are entirely 
unrelated to our systems, but could mistakenly attribute their own vulnerabilities to us.  While we take commercially 

28

 
 
    
 
 
Table of Contents

appropriate steps to safeguard data used by and contained on the systems of our partners, customers and vendors, we cannot 
control all access to those systems and they are therefore subject to potential cyberattacks and fraud.  

Furthermore, as we have increased the number of platforms as well as the size of our networks and information 
systems, our reliance on these technologies have become increasingly important to our operating activities. The potential 
negative impact that a platform, network or information system shutdown may have on our operating activities has 
increased. Shutdowns may be caused by cyberattacks and unexpected catastrophic events such as natural disasters or other 
unforeseen events, such as software or hardware defects or cyber-attacks by groups or individuals.

Under the Financial Services Modernization Act of 1999, also referred to as the “Gramm-Leach-Bliley Act" or 
GLBA, and some state laws, we and WEX Bank are required to maintain a comprehensive written information security 
program that includes administrative, technical and physical safeguards relating to consumer information. This requirement 
generally does not extend to information about companies or about individuals who obtain financial products or services for 
business, commercial, or agricultural purposes.

The GLBA also requires us and WEX Bank to provide initial and annual privacy notices to customers that describe 

in general terms our information sharing practices. If we or WEX Bank intend to share nonpublic personal information 
about consumers with affiliates and/or nonaffiliated third parties, we and WEX Bank must provide customers with a notice 
and a reasonable period of time for each customer to “opt out” of any such disclosure. In addition to U.S. federal privacy 
laws with which we must comply, states also have adopted statutes, regulations and other measures governing the collection 
and distribution of nonpublic personal information about customers. In some cases these state measures are preempted by 
federal law, but if not, we and WEX Bank must monitor and seek to comply with individual state privacy laws in the 
conduct of our businesses.

When we handle individually identifiable health information, regulations issued under Health Insurance Portability 

and Accountability Act of 1996, or HIPAA, and the Health Information Technology for Economic and Clinical Health Act, 
or HITECH, our contracts with our customers, and supplemental state laws require us to implement privacy and data 
security measures and to comply with breach notification requirements.  We may be subject to contractual damages and civil 
or criminal penalties if we are found to violate these privacy, security and breach notification requirements.  

Our efforts to comply with existing and future health and financial data laws and regulations, both in the U.S. and 

abroad, is costly and time-consuming. Incidents involving our handling of this protected and sensitive information may 
consume significant financial and managerial resources and may damage our reputation, which may discourage customers 
from using, renewing, or expanding their use of our services.  

Any security breach, inadvertent transmission of information about our customers, failure to comply with 

applicable breach notification and reporting requirements, or any violation of international, federal or state privacy laws 
could expose us to liability in excess of any applicable insurance policies, litigation, regulatory scrutiny, and/or cause 
damage to our reputation. We may also be required to expend significant resources to implement additional data protection 
measures or to modify the features and functionality of our system offerings in a way that is less attractive to customers. 

Our failure to effectively implement new technology could jeopardize our position as a leader in our industry.

As a provider of information management and payment processing services, we must constantly adapt and respond 

to the technological advances offered by our competitors and the informational requirements of our customers, including 
those related to the Internet, in order to maintain and improve upon our competitive position. We may not be able to expand 
our technological capabilities and service offerings as rapidly as our competitors, which could jeopardize our position as a 
leader in our industry.

We are dependent on technology systems and electronic communications networks managed by third parties, which 
could result in our inability to prevent service disruptions.

Our ability to process and authorize transactions electronically depends on our ability to electronically 
communicate with our fuel and vehicle maintenance providers through point-of-sale devices and electronic networks that 
are owned and operated by third parties. The electronic communications networks upon which we depend are often subject 
to disruptions of various magnitudes and durations. Any severe disruption of one or more of these networks could impair 
our ability to authorize transactions or collect information about such transactions, which, in turn, could harm our reputation 
for dependable service and adversely affect our results of operations. In addition, our ability to collect enhanced data 
relating to our customers’ purchases may be limited by the use of older point-of-sale devices by fuel and vehicle 
maintenance providers. To the extent that fuel and vehicle maintenance providers within our network are slow to adopt 
advanced point-of-sale devices, we may not be able to offer the latest services and capabilities that our customers demand.

29

Our industry continues to become increasingly competitive, which makes it more challenging for us to maintain 
profit margins at historical levels.

We face and expect to continue to face competition in each category of the overall industry from several companies 

that seek to offer competing capabilities and services. Historically, we have been able to provide customers with a wide 
spectrum of services and capabilities and, therefore, we have not considered price to be the exclusive or even the primary 
basis on which we compete. As our competitors have continued to develop their service offerings, it has become 
increasingly more challenging for us to compete solely on the basis of superior capabilities or service. In some areas of our 
business we have been forced to respond to competitive pressures by reducing our fees. We have seen erosion of our 
historical profit margins as we encourage existing strategic relationships to sign long-term contracts. If these trends continue 
and if competition intensifies, our profitability may be adversely impacted.

While we have traditionally offered our services to all categories of the fleet industry, some of our competitors 

have successfully garnered significant share in particular categories of the overall industry. To the extent that our 
competitors are regarded as leaders in specific categories, they may have an advantage over us as we attempt to further 
penetrate these categories.

We also face increased competition in our efforts to enter into new strategic relationships and renew existing 

strategic relationships on similar terms.

Compliance with anti-money laundering laws and regulations creates additional compliance costs and reputational 
risk.

We must monitor and report unusual or suspicious account activity, as well as transactions involving amounts in 

excess of prescribed limits, as required by the Bank Secrecy Act and Internal Revenue Service regulations and other 
regulations. The USA PATRIOT Act of 2001 imposes significant anti-money laundering compliance and due diligence 
obligations on financial institutions, including WEX Bank. Financial regulators have issued various implementing 
regulations and have made enforcement a top priority. Failure to maintain and implement adequate programs to combat 
money laundering and terrorist financing, or to comply with all of the relevant laws or regulations, could result in the 
imposition of fines or penalties and other serious legal and reputational consequences which may impact our financial 
results.

Our increased presence in foreign jurisdictions increases the possibility of foreign law violations or violation of the 
U.S. Foreign Corrupt Practices Act (“FCPA”), the United Kingdom Bribery Act of 2010 (“UKBA”) and the Brazilian 
Anti-Corruption Law ("ACL").

We are subject to the FCPA, the ACL and the UKBA, as we own subsidiaries organized under UK and Brazilian 
law, which serve as a holding companies for other subsidiaries. While the FCPA generally prohibits U.S. companies and 
their intermediaries from making improper payments to foreign officials for the purpose of obtaining or retaining business, 
the UKBA is broader in its reach and prohibits bribery in purely commercial contexts. Any violation of the FCPA, the 
UKBA or similar laws and regulations, including the ACL, could result in significant expenses, divert management 
attention, and otherwise have a negative impact on us. Any determination that we have violated the FCPA, UKBA, ACL or 
laws of any other jurisdiction could subject us to, among other things, penalties and legal expenses that could harm our 
reputation and have a material adverse effect on our financial condition and results of operation. The possibility of 
violations of the FCPA, UKBA, ACL or similar laws or regulations may increase as we expand globally and into countries 
with recognized corruption problems. 

The failure to maintain effective systems of internal control over financial reporting and disclosure controls and 
procedures could result in the inability to accurately report our financial results or prevent material misstatement 
due to fraud, which could cause current and potential shareholders to lose confidence in our financial reporting, 
adversely affect the trading price of our securities, harm our operating results or trigger a default under the 2016 
Credit Agreement.

Effective internal control over financial reporting and disclosure controls and procedures are necessary for us to 

provide reliable financial reports and effectively prevent fraud and operate successfully as a public company. Our financial 
reporting and disclosure controls and procedures are reliant, in part, on information we receive from third parties that supply 
information to us regarding transactions that we process. The failure to develop or maintain effective internal control over 
financial reporting and disclosure controls and procedures could harm our reputation or operating results, or cause us to fail 
to meet our reporting obligations, or trigger a default under the 2016 Credit Agreement. As we expand our business 
operations domestically and internationally, we will need to maintain effective internal control over financial reporting and 

30

 
 
 
 
 
 
Table of Contents

disclosure controls and procedures. If we are unable to do so, our external auditors could issue a qualified opinion on the 
effectiveness of our internal control over financial reporting.

Ineffective internal control over financial reporting and disclosure controls and procedures could cause investors to 

lose confidence in our reported financial information, which could have a negative effect on the trading price of our 
securities or affect our ability to access the capital markets and could result in regulatory proceedings against us by, among 
others, the SEC. In addition, a material weakness in internal control over financial reporting may lead to deficiencies in the 
preparation of financial statements, which in turn could lead to litigation claims against us. The defense of any such claims 
may cause the diversion of management’s attention and resources, and we may be required to pay damages if any such 
claims or proceedings are not resolved in our favor. Any litigation, even if resolved in our favor, could cause us to incur 
significant legal and other expenses. Such events could also affect our ability to raise capital to fund future business 
initiatives.

Our ability to attract and retain qualified employees is critical to our success and the failure to do so may materially 
adversely affect our performance.

We believe our employees, including our executive management team, are our most important resource and, in our 
industry and geographic area, competition for qualified personnel is intense. If we were unable to retain and attract qualified 
employees, our performance could be materially adversely affected.

Risks Relating to Our Common Stock

If any entity controls 10 percent or more of our common stock and such entity has caused a violation of applicable 
banking laws by its failure to obtain any required approvals prior to acquiring that common stock, we have the 
power to, and may be required to, restrict such entity’s ability to vote shares held by it.

As owners of a Utah industrial bank, we are subject to Utah banking regulations that require any entity that 
controls 10 percent or more of our common stock to obtain the prior approval of Utah banking authorities. Federal law also 
prohibits a person or group of persons from acquiring “control” of us unless the FDIC has been notified and has not 
objected to the transaction. Under the FDIC’s regulations, the acquisition of 10 percent or more of a class of our voting 
stock would generally create a rebuttable presumption of control.  In addition, our certificate of incorporation requires that if 
any stockholder fails to provide us with satisfactory evidence that any required approvals have been obtained, we may, or 
will if required by state or federal regulators, restrict such stockholder’s ability to vote such shares with respect to any 
matter subject to a vote of our stockholders.

As a result of these regulatory requirements, certain existing and potential stockholders may choose not to invest or 

invest more in our stock.  This could limit the number of potential investors and impact our ability to attract further funds.

Provisions in our charter documents, Delaware law and applicable banking law may delay or prevent our acquisition 
by a third party.

Our certificate of incorporation and by-laws contain several provisions that may make it more difficult for a third 

party to acquire control of us without the approval of our board of directors. These provisions include, among other things, a 
classified board of directors, the elimination of stockholder action by written consent, advance notice for raising business or 
making nominations at meetings of stockholders and “blank check” preferred stock. Blank check preferred stock enables our 
board of directors, without stockholder approval, to designate and issue additional series of preferred stock with such special 
dividend, liquidation, conversion, voting or other rights, including the right to issue convertible securities with no 
limitations on conversion, and rights to dividends and proceeds in a liquidation that are senior to the common stock, as our 
board of directors may determine. These provisions may make it more difficult or expensive for a third party to acquire a 
majority of our outstanding voting common stock. We also are subject to certain provisions of Delaware law, which could 
delay, deter or prevent us from entering into an acquisition, including Section 203 of the Delaware General Corporation 
Law, which prohibits a Delaware corporation from engaging in a business combination with an interested stockholder unless 
specific conditions are met. These provisions also may delay, prevent or deter a merger, acquisition, tender offer, proxy 
contest or other transaction that might otherwise result in our stockholders receiving a premium over the market price for 
their common stock.

In addition, because we own a Utah industrial bank, any purchaser of our common stock who would own 

10 percent or more of our common stock after such purchase would be required to obtain the consent of Utah banking 
authorities and the federal banking authorities prior to consummating any such acquisition. These regulatory requirements 
may preclude or delay the purchase of a relatively large ownership stake by potential investors.

ITEM 3. LEGAL PROCEEDINGS

On August 11, 2016, the Company was sued in the Circuit Court of St. Charles County, Missouri, in a putative class 
action alleging the Company improperly sent unauthorized facsimile advertisements in violation of the Telephone Consumer 
Protection Act, 47 U.S.C. § 227 (the “TCPA”). The named plaintiff sought to represent a nationwide class of recipients of 
unauthorized facsimile advertisements from the Company (collectively, the "Plaintiffs") and requested statutory damages for 
each facsimile advertisement. The Plaintiffs further alleged that the opt-out notice of the faxes did not meet the criteria set forth 
in the TCPA or its underlying regulations. The Company removed the case to the United States District Court for the Eastern 
District of Missouri on September 15, 2016. On October 14, 2016, the Company filed an answer denying liability and stating 
the facsimile advertisement at issue was sent by FleetOne, LLC, the Company’s wholly-owned subsidiary. On May 10, 2017, 
the parties agreed to a settlement in principle to resolve the class claims, which was preliminarily approved by the court on 
October 6, 2017.  The court entered its final judgment approving the settlement agreement on January 19, 2018.  The settlement 
amount is not material to the Company's financial position, results of operations, cash flows or liquidity.

In addition, from time to time, we are subject to legal proceedings and claims in the ordinary course of business. As of 
the date of this filing, the current estimate of a reasonably possible loss contingency from all legal proceedings is not material to 
the Company's consolidated financial position, results of operations, cash flows or liquidity.

greater than this number of record holders and includes stockholders who are beneficial owners but whose shares are held in street 
name by brokers or nominees.

Dividends

The Company has not declared any dividends on its common stock since it commenced trading on the NYSE on February 16, 
2005. The timing and amount of future dividends, if any, will be (i) dependent upon the Company’s results of operations, financial 
condition, cash requirements and other relevant factors, (ii) subject to the discretion of the Board of Directors of the Company 
and (iii) payable only out of the Company’s surplus or current net profits in accordance with the General Corporation Law of the 
State of Delaware.

The Company has certain restrictions on the dividends it may pay under its revolving credit agreement, including pro 
forma compliance with a ratio of consolidated funded indebtedness to consolidated EBITDA of 2.50:1.00 for the most recent 
period of four fiscal quarters. 

Share Repurchases

On September 23, 2013, we announced a share repurchase program authorizing the purchase of up to $150 million of our 
common stock from time to time which expired on September 30, 2017. On September 20, 2017, our board of directors approved 
a new share repurchase program authorizing the purchase of up to $150 million of our common stock expiring on September 2021. 
Share repurchases are to be made on the open market and can be commenced or suspended at any time.

We did not purchase any shares of our common stock during the year ended December 31, 2017.  The approximate dollar 
value of shares that were available to be purchased under our share repurchase program was $150 million as of December 31, 
2017.

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

The discussion below focuses on the factors affecting our consolidated results of operations for the years ended December 
31, 2017, 2016 and 2015 and financial condition at December 31, 2017 and 2016 and, where appropriate, factors that may affect 
our future financial performance, unless stated otherwise. This discussion should be read in conjunction with the consolidated 
financial statements, notes to the consolidated financial statements and selected consolidated financial data. Our MD&A is presented

2017 Highlights and Year in Review

WEX is a leading provider of corporate payment solutions. Our opportunities for growth extend well beyond the fleet 
fuel market, in particular to the online travel and healthcare payments markets. Building on a leading market position in our core 
fleet business, we continue to expand our company. 

Our strategic approach to entering new markets is focused on three steps:

• 

Identify complicated markets facing complex payment challenges and inefficiencies,

•  Develop products and services that address these unmet market needs, and,

•  Operate with systemic efficiency through scale and cost management. 

We have a proven model in the fleet space where we have developed a leading market position and a strong margin profile. 
We have done the same in the online travel industry where we have become a leader in global virtual payments and continue to 
grow the business and create scale on a global basis. Through the acquisitions of Evolution1 and Benaissance, WEX Health has 
continued to expand into the consumer directed healthcare payments market.

The following events and accomplishments occurred during 2017: 

•  Contributions from all three of our segments resulted in the Company surpassing $1.2 billion in annual revenues 

in 2017, 23% growth relative to the prior year.

•  Effective October 18, the Company acquired certain assets and assumed certain liabilities of AOC, a longstanding 
technology  provider  for  our  virtual  card  product. This  acquisition  will  broaden  the  Company's  capabilities, 
increase our pool of employees with payments platform expertise and allow the Company to evolve with the 
needs of its customers and partners through the use of AOC’s payments processing technology platforms. 

The Company purchased AOC for $130 million, which was funded with cash on hand and through the Company's 
2016 Credit Agreement. 

•  Effective October 30, the Company added $100 million of capacity to its revolving line of credit to provide 

additional liquidity and flexibility.

•  Effective July 3, the Company repriced the secured term loans under the 2016 Credit Agreement, which reduced 
the  applicable  interest  rate  margin  at  current  borrowing  levels  for  both  LIBOR  borrowings  and  base  rate 
borrowings for the Company's tranche A term loans and tranche B term loans, 50 basis points and 75 basis points, 
respectively. Based on amounts outstanding under these term loans at December 31, the repricing is expected 
to provide an annualized savings of approximately $11 million in interest expense, approximately half of which 
was realized in 2017.

•  On  December  20,  the  Company  entered  into  two  additional  forward-fixed  interest  rate  swap  agreements  to 
manage  the  interest  rate  risk  associated  with  $500  million  of  outstanding  variable-interest  rate  borrowings. 
Commencing December 2017, the Company will receive variable interest of 1-month LIBOR under these swaps 
and will pay a weighted average annualized fixed rate of 2.21% over the five year term. With the commencement 

35

 
 
 
 
 
Table of Contents

of these interest rate swaps, we have reduced the variability of the future interest payments associated with $1.7 
billion of our borrowings, including our fixed rate notes outstanding.

Our Company's management believes the following metrics were important to our overall performance in 2017:

•  Average number of vehicles serviced increased 9 percent from 2016 to approximately 10.9 million for 2017, 
primarily related to growth in our worldwide customer base. As of December 31, 2017, vehicles serviced totaled 
11.4 million.

•  Total fleet transactions processed increased 14 percent from 2016 to 516.8 million in 2017. Payment processing 
transactions increased 11 percent from 2016 to 429.7 million in 2017, and transaction processing transactions 
increased 27 percent from 2016 to 87.1 million in 2017. The increase in payment processing transactions resulted 
from a large customer portfolio converting from a transaction processing relationship to a payment processing 
relationship late in 2016, the acquisition of EFS and organic growth. The primary driver for the increase in 
transaction processing transactions was due to the acquisition of EFS, partially offset by the portfolio conversion 
mentioned above. 

•  Average expenditure per payment processing transaction in our Fleet Solutions segment increased 19 percent
to $70.49 for 2017, from $59.19 in 2016. The average U.S. fuel price per gallon during 2017 was $2.50, a 13 
percent increase as compared to the same period in the prior year. 

•  Credit loss expense in the Fleet Solutions segment was $59.3 million during 2017, as compared to $27.3 million 
during 2016, resulting primarily from higher incidences of magnetic stripe card skimming fraud during 2017. 
Spend volume increased 33 percent in 2017 as compared to 2016. Our credit losses were 17.2 basis points of 
fuel expenditures for 2017, as compared to 11.1 basis points of fuel expenditures for 2016.

•  Our Travel and Corporate Solutions purchase volume grew to $30.3 billion in 2017, a 27 percent increase from 
2016. This increase is primarily driven by worldwide organic growth, most notably in the U.S. and Europe. This 
favorable impact was offset by changes in the net interchange rate for this segment, which decreased 29% in 
2017 as compared to 2016 due to contract renegotiations with one of our large partners.

•  Our foreign currency exchange exposure is primarily related to the re-measurement of our cash, receivable and 
payable balances that are denominated in foreign currencies. Movements in the exchange rates associated with 
our foreign held currencies resulted in a gain of $29.9 million in 2017, as compared to a loss of $7.7 million in 
2016.

•  Our effective tax rate was 10.9 percent for 2017 as compared to 34.0 percent for 2016. The decline in our tax 
rate is primarily due the reduction of our net deferred tax liabilities resulting from the change in federal corporate 
income tax rate to 21 percent from 35 percent effective January 1, 2018 as part of the 2017 Tax Cuts and Jobs 
Act (the "2017 Tax Act"), partly offset by the increase in valuation allowance. Our federal income tax expense 
for periods beginning in 2018 will be based on the new rate. Future tax rates may fluctuate due to changes in 
the mix of earnings among different tax jurisdictions, as well as impacts that tax rate and earnings mix changes 
have on our net deferred tax assets. 

• 

Financing interest expense decreased $6.4 million in 2017, as compared to 2016. The decrease resulted from 
the absence of certain ticking fees incurred in 2016, partly offset by higher relative average borrowings and 
effective interest rates.

Segments

WEX operates in three reportable segments: Fleet Solutions, Travel and Corporate Solutions, and Health and Employee 
Benefit Solutions. The Fleet Solutions segment provides payment, transaction processing and information management services 
specifically designed for the needs of commercial and government fleets. The Travel and Corporate Solutions segment focuses on 
the complex payment environment of business-to-business payments, providing customers with payment processing solutions for 
their corporate payment and transaction monitoring needs. The Health and Employee Benefit Solutions segment provides a SaaS 
platform for consumer directed healthcare payments, as well as payroll related benefits to customers in Brazil.

Results of Operations

The Company does not allocate foreign currency gains and losses, financing interest expense, unrealized and realized 
gains and losses on derivative instruments and non-cash adjustments related to our tax receivable agreement to our operating 
segments as management believes these items are unpredictable and can obscure underlying trends.

Key operating statistics have been modified to provide added insight into segment revenue trends. Metrics for the years ended December 31, 2016 and 2015 

have also been conformed to the current year presentation.

 Revenues

Payment processing revenue increased $62.3 million for 2017, as compared to 2016, due primarily to the impact of a 
13% increase in the annual average domestic price per gallon of fuel and higher payment processing volumes. Higher volumes 
resulted from organic growth, the acquisition of EFS and a large customer portfolio converting from a transaction processing 
relationship to a payment processing relationship in the beginning of 2016. These favorable factors were partly offset by a decrease 
in our interchange rate as result of the large portfolio conversion mentioned above. 

Account  servicing  revenue  increased  $38.0  million  for  2017,  as  compared  to  2016,  resulting  from  worldwide  price 

modernization efforts over the course of the prior year and the EFS acquisition. 

Other  revenues  increased  $46.1  million  in  2017,  as  compared  to  2016,  resulting  primarily  from  higher  transaction 

processing revenue due to the acquisition of EFS and additional pricing modernization efforts.

Late fee revenue is primarily fees charged for receivables not paid within the terms of the customer agreement based 
upon the outstanding customer receivable balance. Late fee revenue is earned when a customer’s receivable balance becomes 
delinquent and is calculated using the greater of a minimum charge or a stated late fee rate multiplied by the outstanding balance 
that is subject to a late fee charge. Changes in the absolute amount of such outstanding balances can be attributed to changes in 
(i) fuel prices; (ii) customer specific transaction volume; and (iii) customer specific delinquencies. Late fee revenue can also be 
impacted by changes in (i) late fee rates and (ii) increases or decreases in customer overdue balances. Late fee rates are determined 
and set based primarily on the risk associated with our customers, coupled with a strategic view of standard rates within our 
industry. Periodically, we assess the market rates associated within our industry to determine appropriate late fee rates. We consider 
factors such as the Company’s overall financial model and strategic plan, the cost to our business from customers failing to pay 
timely and the impact such late payments have on our financial results. These assessments are typically conducted at least annually 
but may occur more often depending on macro-economic factors.

Late fee revenue increased $23.3 million in 2017, as compared to 2016, due to the change in overdue balances. For the 
majority of 2016, late fee ranges and minimum charges were 0 to 6.99 percent monthly and $75, respectively.  For the majority 
of 2017, late fee ranges were 0 to 7.99 percent monthly, with minimum charges of $75. The weighted average late fee rate, net of 
related charge-offs was 4.4% and 4.3% for 2017 and 2016, respectively.

Concessions to certain customers experiencing financial difficulties may be granted and are limited to extending the time 
to pay, placing a customer on a payment plan or granting waivers of late fees. There were no material concessions to customers 
experiencing financial difficulties during both the years ended December 31, 2017 and 2016. Though not material, the Company 
granted certain concessions to domestic customers impacted by hurricanes and forest fires during 2017.

The primary source of factoring fee revenue is calculated as a negotiated percentage fee of the receivable balance that 
we purchase. A secondary source of factoring fee revenue is a flat rate service fee to our customers that request a non-contractual 
same day funding of the receivable balance. Factoring fee revenue increased $9.3 million in 2017, as compared to 2016. The 
increase in factoring fee revenue is due to organic growth and customer demand for our services.

Salary and other personnel expenses increased $57.2 million for 2017, as compared to 2016, due primarily to resources 
assumed as part of the EFS acquisition, as well as personnel to support the in-sourcing of technology functions from a third party  
provider and business growth. Additionally, we recognized higher expenses associated with variable compensation plans based 
on performance.

We  incurred  restructuring  costs  of  approximately  $6.2  million  and  $7.5  million  for  2017  and  2016,  respectively. 
Restructuring costs decreased due to the wind-down of prior year restructuring initiatives related to our European Fleet business, 
partly offset by employee costs and office closure costs associated with our EFS acquisition, which are expected to be paid through 
2018.

Service fees decreased $26.8 million during 2017, as compared to 2016, primarily due to one-time expenses associated 
with the acquisition of EFS as well as costs to outsource certain back office technology incurred during 2016, partly offset by an 
increase in professional fees.

Provision for credit losses increased $32.0 million for 2017, as compared to 2016, resulting from higher incidences of 
magnetic stripe card skimming fraud during 2017. Additionally, credit losses were impacted by higher relative fuel spend and the 
acquisition of EFS. During 2017, the Company took a number of steps to combat fraud losses, including establishing portfolio 
limits on the number of transactions and amount of fuel purchases. Additionally, we implemented new real-time technology during 
the fourth quarter of 2017, designed to increase fraud detection speed.  As a result of these actions, monthly fraud losses trended 
downwards in the second half of 2017, most significantly in the fourth quarter. We anticipate that fraud incidents will continue to 
trend down slightly in terms of size and frequency in 2018.

We generally measure our credit loss performance by calculating credit losses as a percentage of total fuel expenditures 
on  the  payment  processing  transactions. This  metric  for  credit  losses  was  17.2  basis  points  of  fuel  expenditures  for  2017,  as 
compared to 11.1 basis points of fuel expenditures for 2016. We generally use a roll rate methodology to calculate the amount 
necessary  for  our  ending  receivable reserve  balance. This  methodology  considers  total receivable  balances,  recent  charge  off 
experience, recoveries on previously charged off accounts, and the dollars that are delinquent to calculate the total reserve. In 
addition, management undertakes a detailed evaluation of the receivable balances to help further ensure overall reserve adequacy. 
The expense we recognize in each quarter is the amount necessary to bring the reserve to its required level based on accounts 
receivable aging and net charge offs. 

Technology leasing and support expenses increased $7.6 million in 2017, as compared to 2016. This increase is primarily 
due to additional software licensing expense and maintenance, resulting from incremental technological investments in our Fleet 
Solutions business, including EFS.

Depreciation and amortization increased $42.4 million in 2017, as compared to 2016, due primarily to a full year of 
amortization of intangibles acquired in the EFS acquisition. Refer to Item 8 – Note 3, Business Acquisition of this report for more 
information. Additionally, following the acquisition of EFS, we evaluated the estimated useful life of our existing over-the-road 
payment processing technology. As a result of this analysis, we accelerated amortization related to this technology during the third 
quarter of 2016, resulting in incremental amortization during 2017 as compared to the same period in the prior year. This technology 
is fully amortized as of December 31, 2017.

Operating interest expense increased $5.1 million in 2017, as compared to 2016, primarily due to higher interest rates 
paid on recently issued certificates of deposit, which replaced previously held non-interest bearing deposits following the expiration 
of an agreement with a deposit partner during the fourth quarter of 2016. Additionally, payment processing volume increases and 
higher fuel prices contributed to the increase in operating interest expense.

During the second quarter of 2017, we incurred a $16.2 million non-cash impairment and asset write-off related to in-
sourcing certain technology functions. Additionally, as part of a recent technology plan assessment, we streamlined certain payment 
processing software offerings and incurred a $5.9 million non-cash software impairment and asset write-off charge.

During 2017, management determined that our Telapoint business did not align with the long-term strategy of our core 
Fleet business. During November 2017, the Company sold net assets of $8.9 million of this business, which resulted in a pre-tax 
book gain of approximately $21.0 million. 

All other operating expenses increased $16.4 million in 2017, as compared to 2016, resulting primarily from higher costs 

to support business growth, including incremental expenses as result of the EFS acquisition.

Revenues

Payment processing revenue decreased approximately $17.1 million for 2017, as compared to 2016, primarily due to a 
decrease in our net interchange rate resulting from contract renegotiations with a large travel customer which went into effect in 
January 2017. This unfavorable factor was partly offset by an increase in corporate charge card purchase volume from our WEX 
travel product in all our markets, most notably the U.S. and Europe, and the acquisition of EFS. 

Account servicing revenue increased approximately $6.3 million for 2017, as compared to 2016, primarily due to the 

acquisition of AOC.

Other revenue increased approximately $19.5 million, primarily due to higher international settlement fees.

Concessions to certain customers experiencing financial difficulties may be granted and are limited to extending the time 
to pay, placing a customer on a payment plan or granting waivers of late fees. As of December 31, 2017 and 2016, customer 
balances with such concessions totaled $7.9 million and $16.7 million, respectively. The Company waived $2.1 million and $1.3 
million in late fees in 2017 and 2016, respectively.

Service fees decreased by $6.1 million in 2017, as compared to 2016, due primarily to lower network processing fees 
paid as a result of our MasterCard contract renewal executed during the third quarter of 2016, partly offset by incremental expenses 
resulting from higher relative purchase volumes.

Provision for credit losses decreased $5.7 million in 2017, as compared to 2016. Prior year results were negatively impacted 
by two discrete credit losses, including the bankruptcy of one of our online travel agency customers. We recovered a portion of 
this prior year provision for credit loss during 2017.

Technology leasing and support decreased $4.4 million in 2017, as compared to 2016, due primarily to cost savings as a 

result of the AOC acquisition. Prior to its acquisition, AOC was one of the Company's important technology providers.

Depreciation and amortization expenses increased $11.5 million in 2017, as compared to 2016, due to a full year of 

amortization of intangibles acquired in the EFS acquisition and amortization from our recent AOC acquisition. 

Operating interest increased $5.4 million in 2017, as compared to 2016, due to higher deposit interest rates. Following 
the expiration of an agreement with a deposit partner during the fourth quarter of 2016, we issued certificates of deposit to replace 
previously held non-interest bearing deposits. Additionally, higher payment processing volumes contributed to the increase in 
operating interest expense.

Following the acquisition of AOC in the fourth quarter of 2017, the Company reevaluated certain payment processing 
software under development. In doing so, we determined the developed technology obtained as part of the AOC acquisition more 
closely aligns with our current technological strategy. As result, $22.0 million of previously capitalized software development was 
determined to have no future benefit and was therefore written off during 2017.

All other operating expenses decreased $14.0 million in 2017, as compared to 2016. 2016 results were negatively impacted 
by a one-time $15.5 million vendor settlement executed in 2016 in exchange for the release of potential claims related to in-
sourcing certain technology.

have also been conformed to the current year presentation.

Revenues

Payment processing revenue increased approximately $3.4 million for 2017, as compared to 2016, resulting primarily 
from an increase in WEX Health purchase volume due to growth in consumers, partly offset by a slight decline in WEX Latin 
America revenues.

Table of Contents

Account servicing revenue increased $21.3 million for 2017, as compared to 2016. This increase was primarily due to 
WEX Health customer signings and existing customer growth, which resulted in a higher number of participants using our SaaS 
healthcare technology platform.

Finance fee revenue increased $13.9 million in 2017, as compared to 2016, due primarily to growth in revenue earned 

on our salary advance product in Brazil.

Concessions to certain customers experiencing financial difficulties may be granted and are limited to extending the time 
to pay, placing a customer on a payment plan or granting waivers of late fees. There were no material concessions granted during 
either of the years ended December 31, 2017 or 2016.

Other revenue increased $3.8 million in 2017, as compared to 2016, resulting primarily from an increase in Brazil card 

transactions and  higher ancillary WEX Health fees as result of a growing customer base.

Salary and other personnel expenses increased $13.4 million in 2017, as compared to 2016, primarily due to higher average 
WEX Health and WEX Latin America headcount and related employee benefit costs in support of significant business growth. 
Additionally, we recognized higher expenses associated with variable compensation plans based on performance.

Service fees increased by $8.9 million in 2017, as compared to 2016, primarily due to costs incurred as a result of the 

increase in participants using our SaaS healthcare offerings.

Depreciation and amortization expenses increased $8.1 million in 2017, as compared to 2016, resulting from incremental 

amortization of acquired intangibles and higher depreciation expense primarily on capitalized software development costs.

Operating interest increased $1.6 million in 2017, as compared to 2016, primarily due to an increase in customer receivable 

balances due to business growth and higher relative average interest rates. 

All other operating expenses increased $6.8 million in 2017, as compared to 2016, primarily due to expenses to support 

significant business growth and higher revenue-based taxes in Brazil.

Financing interest expense decreased $6.4 million in 2017, as compared to 2016. 2016 was unfavorably impacted by $30 
million of ticking fees incurred for the commitment of funds to finance the acquisition of EFS. The absence of this expense in 
2017 was partly offset by higher relative borrowings and effective interest rates under the 2016 Credit Agreement. The Company 
recently completed two separate repricings of the 2016 Credit Agreement which reduced the applicable interest rate margin on 

42

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

outstanding term loans going forward. See Item 8 - Note 13, Financing Debt  and Note 25, Subsequent Event for further information 
regarding these repricings.

Our foreign currency exchange exposure is primarily related to the re-measurement of our cash, receivable and payable 
balances, including intercompany transactions that are denominated in foreign currencies. In 2017, net foreign currency gain was 
$29.9 million, as compared to a net foreign currency loss of $7.7 million in 2016. In 2017, we recognized gains on trade receivables 
and intercompany loans primarily from a strengthening of the British Pound Sterling and the Euro relative to the US dollar. In 
2016, we experienced foreign currency exchange losses from fluctuations in exchange rates that resulted in a significant devaluation 
of major currencies to which our business is exposed, including the British Pound Sterling, the Euro and the Australian dollar. 

Net unrealized gains on interest rate swap agreements was $1.3 million in 2017, as compared to $12.9 million in 2016. 
In 2017, the favorable impact of increases in the variable interest rates on our swap agreements was almost entirely offset by the 
decrease in remaining swap duration.

Non-cash adjustments related to tax receivable agreement were $15.3 million in 2017 resulting from a decrease in a tax 
sharing liability due to our former parent company as result of recent tax reform which reduced the federal statutory rate from 
35% to 21%.

INCOME TAXES

Our effective tax rate was 10.9 percent for 2017 as compared to 34.0 percent for 2016. The decline in our tax rate is 
primarily due the reduction of our net deferred tax liabilities resulting from the change in federal corporate income tax rates effective 
January 1, 2018 as part of the 2017 Tax Act, partly offset by the increase in valuation allowance.

In December 2017, the 2017 Tax Act was signed into law making significant changes to the Internal Revenue Code. 
Changes include, but are not limited to, a federal corporate tax rate decrease from 35 percent to 21 percent for tax years beginning 
after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system and a 
one-time transition tax on the mandatory deemed repatriation of foreign earnings. The Company has estimated the provision for 
income taxes in accordance with the 2017 Tax Act and guidance available as of the date of this filing and as a result has recorded 
a provisional amount of one-time income tax benefit of approximately $60 million in the fourth quarter of 2017, the period in 
which the legislation was enacted. This benefit was primarily related to the remeasurement of certain deferred tax assets and 
liabilities based on the tax rates at which they are expected to reverse in the future and a reduction in the amount due under our 
tax receivable agreement, which decreased primarily as a result of the decline in the federal corporate income tax rate. These 
favorable  impacts  were  partly  offset  by  income  tax  expense  related  to  the  one-time  transition  tax  on  the  mandatory  deemed 
repatriation of foreign earnings.

The 2017 Tax Act also changes the taxation of foreign earnings, and companies generally will not be subject to United     

States federal income taxes upon the receipt of dividends from foreign subsidiaries and will not be permitted foreign tax credits 
related to such dividends. However, the 2017 Tax Act creates a new requirement to tax certain foreign earnings relating to Global 
Intangible Low Taxed Income (“GILTI”). Based on the recent FASB guidance, the Company can elect an accounting policy choice 
of either treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred 
or factoring such amounts into the Company’s measurement of its deferred taxes. Because of the complexity of the new GILTI 
tax rules, and anticipated guidance from U.S. Treasury we will continue to evaluate this provision of the 2017 Tax Act.  Therefore, 
we have not recorded any deferred taxes related to GILTI and have not elected an accounting policy for GILTI at this time.

Undistributed earnings of certain foreign subsidiaries of the Company amounted to approximately $59 million and $26 
million at December 31, 2017 and 2016, respectively. These earnings are considered to be indefinitely reinvested. Beginning in 
2018, except for GILTI, the Company will no longer record United States federal income tax on its share of the income of its 
foreign subsidiaries, nor will it record a benefit for foreign tax credits related to that income. 

On December 22, 2017, Staff Accounting Bulletin No. 118 was issued to address the application of U.S. GAAP in situations 
when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable 
detail to complete the accounting for certain income tax effects of the Act. Accordingly, any subsequent adjustments to the amount 
of one-time benefit noted above will be recorded to current income tax provision during the measurement period which is not 
expected to extend beyond one year from the enactment date. The effects of other provisions of the 2017 Tax Act are not expected 
to have a material impact on our results of operations.

have conformed to the current year presentation. As of July 1, 2016, these key operating statistics include our EFS acquisition.

Revenues

Payment processing revenue decreased $8.0 million for 2016, as compared to 2015, due primarily to the impact of a 13% 
decrease in the average domestic price per gallon of fuel in the 2016 as compared to 2015 and the unfavorable impact of foreign 
currency  exchange  rates. These  unfavorable  factors  were  partly  offset  by  a  higher  payment  processing  volume  related  to  the 
acquisition of EFS, a large customer portfolio converting from a transaction processing relationship to a payment processing 
relationship in the beginning of 2016 and organic growth. 

Account servicing revenue increased $26.3 million for 2016, as compared to 2015, resulting from the acquisition of EFS 

and organic growth from an increase in fees to certain customers as part of our price modernization efforts. 

Other revenues increased $34.9 million in 2016, as compared to 2015, primarily due to the acquisition of EFS.

Late fees increased $35.5 million in 2016, as compared to 2015. The increase in late fees was primarily due to $39.1 
million due to rate increases, partly offset by a decrease of $3.6 million due to the change in overdue balances. During the first 
half of 2015, late fee rates ranged from 0 to 3.75 percent monthly with a minimum late fee charge of $50. For the second half of 
2015, late fee rate ranges and minimum charges were 0 to 5.50 percent monthly and $75, respectively. During the second quarter 
of 2016, late fee ranges were changed to 0 to 6.99 percent monthly, while minimum charges remained at $75. The weighted average 
late fee rate, net of related charge-offs was 4.3% and 2.6% for 2016 and 2015, respectively. 

Concessions to certain customers experiencing financial difficulties may be granted and are limited to extending the time 
to pay, placing a customer on a payment plan or granting waivers of late fees. There were no material concessions to customers 
experiencing financial difficulties during either of the years ended December 31, 2016 and 2015.

Salary and other personnel expenses increased $30.7 million for 2016, as compared to 2015, due primarily to the acquisition 

of EFS, and to a lesser extent, increases in variable compensation plans and employee benefit costs. 

We recorded restructuring costs of approximately $7.5 million and $9.0 million for 2016 and 2015, respectively. The 
costs primarily reflect employee termination benefits and office closing costs to be paid through 2018. These initiatives are expected 
to streamline our domestic and international fleet businesses, driving acquisition synergies and creating greater efficiencies. 

Service fees increased $32.5 million during 2016, as compared to 2015. The increase is due primarily to expenses associated 

with the acquisition of EFS and costs to outsource certain back office technology. 

Provision for credit losses increased $6.4 million for 2016, as compared to 2015. We generally measure our credit loss 
performance by calculating credit losses as a percentage of total fuel expenditures on the payment processing transactions. This 
metric for credit losses was 11.9  basis points of fuel expenditures for 2016, as compared to 9.4 basis points of fuel expenditures 
for 2015. We generally use a roll rate methodology to calculate the amount necessary for our ending receivable reserve balance. 
This methodology considers total receivable balances, recent charge off experience, recoveries on previously charged off accounts, 
and the dollars that are delinquent to calculate the total reserve. In addition, management undertakes a detailed evaluation of the 
receivable balances to help further ensure overall reserve adequacy. The expense we recognize in each quarter is the amount 
necessary to bring the reserve to its required level based on accounts receivable aging and net charge offs. 

Technology leasing and support expenses increased $3.7 million in 2016, as compared to 2015, resulting from additional 

software maintenance expense, due primarily to the EFS acquisition. 

Occupancy and equipment increased $2.9 million in 2016, as compared to 2015, due primarily to higher rent expense, 

the majority of which resulted from the EFS acquisition. 

Depreciation and amortization increased $46.4 million in 2016, as compared to 2015, due primarily to amortization of 
intangibles obtained from the EFS acquisition. Additionally, the Company evaluated the estimated useful life of our existing over-
the-road payment processing technology following the EFS acquisition. As a result of this analysis, we recorded approximately 
$10.1 million of accelerated amortization related to this technology during the second half of 2016 and will amortize approximately 
$11.5 million of remaining net book value associated with this technology over the next six months. 

Other expenses increased $5.3 million in 2016, as compared to 2015, resulting primarily from the EFS acquisition.

Revenues

Payment processing revenue increased approximately $24.5 million for 2016, as compared to 2015, primarily due to an 
increase in corporate charge card purchase volume from our WEX travel product and the acquisition of EFS. These favorable 
impacts were partly offset by the unfavorable impact of foreign currency exchange rates, and a decrease in the virtual card net 
interchange rate resulting from contract renegotiations and increased volumes in 2016 from certain large customers resulting in 
higher rebates. In the fourth quarter of 2016, we renegotiated our contract with one of our large customers, which will increase 
the rebates we provide to them effective in the first quarter of 2017. 

Other revenue decreased approximately $4.3 million, primarily due to lower rates charged on cross border 

transactions. 

Concessions to certain customers experiencing financial difficulties may be granted and are limited to extending the time 
to pay, placing a customer on a payment plan or granting waivers of late fees. As of and for the year ended December 31, 2016, 
customer balances with such concessions totaled $16.7 million and resulted in approximately $1.3 million in waived late fees.

Revenues

Payment processing revenue increased approximately $8.3 million for 2016, as compared to 2015, due primarily to 

higher spend volumes resulting from the growth of WEX Health interchange consumers. 

Account servicing revenue increased $28.7 million for 2016, as compared to 2015. This increase was due primarily to 

WEX Health new and existing customer growth, which resulted in a higher number of participants using our SaaS healthcare 
offerings, and revenues from Benaissance, which was acquired in November 2015. 

Finance fee revenue increased $8.5 million in 2016, as compared to 2015, due primarily to organic growth in revenue 

earned on our salary advance product in Brazil resulting from an increase in the number of installments selected by our 
customers in 2016 as compared to the prior year. 

Concessions to certain customers experiencing financial difficulties may be granted and are limited to extending the 

time to pay, placing a customer on a payment plan or granting waivers of late fees. There were no material concessions granted 
during either of the years ended December 31, 2016 or 2015. 

Other revenue increased $4.2 million in 2016, as compared to 2015, due primarily to growth and other ancillary fees

facility leasing costs from the acquisition of Benaissance and growth of our WEX Health facilities and related costs. 

Depreciation and amortization expenses increased $9.0 million in 2016, as compared to 2015. This increase resulted 
from higher amortization expense, primarily on acquired Benaissance intangibles and capitalized software development costs.

Financing interest expense increased $67.2 million in 2016, as compared to 2015. The increase was primarily due to 
ticking fees incurred for the commitment of funds to finance the acquisition of EFS and higher relative borrowings and effective 
interest rates under the 2016 Credit Agreement.

Net foreign currency loss increased $2.0 million in 2016, as compared to 2015. In both 2016 and 2015, most prominently 
in the fourth quarter of each year, we experienced losses from fluctuations in exchange rates that resulted in a significant devaluation 
of major currencies to which our business is exposed, including the British Pound Sterling, the Euro and the Australian dollar. In 
2016, this unfavorable factor was partly offset by recognized foreign currency gains related to intercompany loans resulting from 
a strengthening of the Euro against the British Pound Sterling. 

In November 2016, the Company entered into three forward-fixed interest rate swap agreements to manage the interest 
rate risk associated with our outstanding variable-interest rate borrowings. These derivative instruments do not qualify for hedge 
accounting. Accordingly, realized and unrealized gains and losses on these derivative instruments affect our net income. During 
2016, we recorded an unrealized gain of $12.9 million on these interest rate swap agreements. 

INCOME TAXES

Our effective tax rate was 34.0 percent for 2016 as compared to 40.7 percent for 2015. The change in our tax rate reflects 
a shift in jurisdictional profitability between 2015 and 2016. Increased profits in 2016 within tax jurisdictions with tax rates lower 
than the United States resulted in a reduction to our effective tax rate. Our 2016 tax rate reflects the release of certain historical 
foreign reserve positions in Australia, primarily driven by a lapse of statute, as well as a reduction in our domestic production 
activities deduction as a result of lower taxable income in the United States.

NON-GAAP FINANCIAL MEASURES

The Company's non-GAAP adjusted net income excludes unrealized gains and losses on derivatives, net foreign currency 
remeasurement gains and losses, acquisition-related ticking fees, acquisition-related intangible amortization, other acquisition and 
divestiture related items, stock-based compensation, restructuring and other costs, gain on divestiture, a one-time vendor settlement, 
debt restructuring and debt issuance cost amortization, non-cash adjustments related to tax receivable agreement, reserves for 
regulatory penalties, adjustments attributed to our non-controlling interest and certain tax related items. In addition, for the three 
months and year ended December 31, 2017, we have excluded certain impairment charges and asset write-offs as described below. 

Although adjusted net income is not calculated in accordance with GAAP, this non-GAAP measure is integral to the 
Company's reporting and planning processes and the chief operating decision maker of the Company uses adjusted operating 
income to allocate resources among our operating segments. The Company considers this measure integral because it excludes 
the above-specified items that the Company's management excludes in evaluating the Company's performance. Specifically, in 

48

 
 
 
 
 
 
 
 
 
 
Table of Contents

addition to evaluating the Company's performance on a GAAP basis, management evaluates the Company's performance on a 
basis that excludes the above items because: 

•  Exclusion of the non-cash, mark-to-market adjustments on derivative instruments, including fuel-price related derivatives 
and interest rate swap agreements, helps management identify and assess trends in the Company's underlying business 
that might otherwise be obscured due to quarterly non-cash earnings fluctuations associated with these derivative contracts. 
The  non-cash,  mark-to-market  adjustments  on  derivative  instruments  are  difficult  to  forecast  accurately,  making 
comparisons across historical and future quarters difficult to evaluate. 

•  Net foreign currency gains and losses primarily result from the remeasurement to functional currency of cash, receivable 
and payable balances, certain intercompany notes denominated in foreign currencies and any gain or loss on foreign 
currency hedges relating to these items. The exclusion of these items helps management compare changes in operating 
results between periods that might otherwise be obscured due to currency fluctuations. 

•  The  Company  considers  certain  acquisition-related  costs,  including  certain  financing  costs,  ticking  fees,  investment 
banking  fees,  warranty  and  indemnity  insurance,  certain  integration  related  expenses  and  amortization  of  acquired 
intangibles, as well as gains and losses from divestitures to be unpredictable, dependent on factors that may be outside 
of our control and unrelated to the continuing operations of the acquired or divested business or the Company. In addition, 
the size and complexity of an acquisition, which often drives the magnitude of acquisition-related costs, may not be 
indicative of such future costs. The Company believes that excluding acquisition-related costs and gains or losses of 
divestitures facilitates the comparison of our financial results to the Company's historical operating results and to other 
companies in our industry. 

• 

Stock-based compensation is different from other forms of compensation, as it is a non-cash expense. For example, a 
cash salary generally has a fixed and unvarying cash cost. In contrast, the expense associated with an equity-based award 
is generally unrelated to the amount of cash ultimately received by the employee, and the cost to the Company is based 
on a stock-based compensation valuation methodology and underlying assumptions that may vary over time. 

•  Restructuring and other costs include employee termination benefits from certain identified initiatives to further streamline 
the business, improve the Company's efficiency, create synergies and to globalize the Company's operations, all with an 
objective to improve scale and increase profitability going forward. We exclude these items when evaluating our continuing 
business performance as such items are not consistently occurring and do not reflect expected future operating expense, 
nor provide insight into the fundamentals of current or past operations of our business. 

• 

Impairment charges and asset write-offs represent non-cash asset write-offs related to the following: 

Impairment of certain prepaid services following a strategic decision to in-source certain technology functions.

Impairments of certain payment processing software following the acquisition of AOC and as part of our ongoing 
platform consolidation strategy, designed to ensure we continue to deliver superior technology to our customers.

These charges do not reflect recurring costs that are relevant to our continuing operations. The Company believes that 
excluding these nonrecurring expenses facilitates the comparison of our financial results to the Company's historical 
operating results and to other companies in our industry. 

•  Vendor  settlement  represents  a  payment  in  exchange  for  the  release  of  potential  claims  related  to  insourcing  certain 
technology, and does not reflect recurring costs that would be relevant to the continuing operations of the Company. The 
Company believes that excluding this nonrecurring expense facilitates the comparison of our financial results to the 
Company's historical operating results and to other companies in our industry. 

•  Debt restructuring and debt issuance cost amortization are non-cash items that are unrelated to the continuing operations 
of the Company. Debt restructuring costs are not consistently occurring and do not reflect expected future operating 
expense, nor provide insight into the fundamentals of current or past operations of our business. In addition, since debt 
issuance cost amortization is dependent upon the financing method which can vary widely company to company, we 
believe that excluding these costs helps to facilitate comparison to historical results as well as to other companies within 
our industry.

•  The  adjustments  attributable  to  non-controlling  interests,  including  adjustments  to  the  redemption  value  of  a  non-
controlling interest, and the non-cash adjustments related to our tax receivable agreement have no significant impact on 
the ongoing operations of the business.

•  Regulatory reserves reflect charges related to the impact of a regulatory action which resulted in WEX paying a penalty 
in 2016. We have excluded this item when evaluating our continuing business performance as it is not consistently recurring 
and does not reflect an expected future operating expense, nor provide insight into the fundamentals of the current or past 
operations of our business.  

•  The tax related items are the difference between the Company’s U.S. GAAP tax provision and a pro forma tax provision 
based upon the Company’s adjusted net income before taxes as well as the impact from certain discrete tax items. The 
methodology utilized for calculating the Company’s adjusted net income tax provision is the same methodology utilized 
in calculating the Company’s U.S. GAAP tax provision. 

For the same reasons, WEX believes that adjusted net income may also be useful to investors as one means of evaluating 
the Company's performance. However, because adjusted net income is a non-GAAP measure, it should not be considered as a 
substitute for, or superior to, net income, operating income or cash flows from operating activities as determined in accordance 
with GAAP. In addition, adjusted net income as used by WEX may not be comparable to similarly titled measures employed by 
other companies.

LIQUIDITY, CAPITAL RESOURCES AND CASH FLOWS

We believe that our cash generating capability, financial condition and operations, together with our revolving credit 
agreement, term loans, and notes outstanding, as well as other available methods of financing (including deposits, participation 
loans, borrowed federal funds, and securitization facilities), will be adequate to fund our cash needs for at least the next 12 months.

•  Cash provided by operating activities was primarily due to higher net income adjusted for non-cash charges. This favorable 

factor was partly offset cash used by accounts receivables, net of associated payables.

50

 
 
 
 
 
 
 
Table of Contents

•  Cash  used  by  investing  activities  was  due  to  the  acquisition  of AOC  and  capital  additions  primarily  related  to  the 
development  of  internal-use  software  as  we  expand  globally  and  provide  competitive  products  and  services  to  our 
customers. These impacts were partly offset by the sale of our Telapoint business after determining that its operations did 
not align with the core strategy of our Fleet business. The AOC acquisition was funded with cash on hand and through 
the Company's 2016 Credit Agreement. 

•  The Company added $100 million of capacity to its revolving line of credit to provide additional liquidity and flexibility.

•  Cash provided by financing activities resulted from increased bank deposits to fund accounts receivable, borrowings 
under the 2016 Credit Agreement associated with the AOC acquisition and increased third-party bank participation in 
customer receivables.

2016 Highlights

•  On July 1, 2016, we completed the acquisition of EFS, a provider of customized corporate payment solutions for fleet 
and corporate customers with a focus on the large and mid-sized over-the-road fleet segments for approximately $1.4 
billion in cash and stock consideration. 

In conjunction with the EFS acquisition, we successfully closed on the 2016 Credit Agreement, which increased our 
available financing. The 2016 Credit Agreement provides for term loan facilities in the amount of $1.7 billion, a $470 
million secured revolving credit facility and the option for additional loans subject to certain criteria. 

•  During 2016, our increase in accounts receivable resulted in a $442.3 million use of cash, net of the customer receivables 
acquired as part of the EFS acquisition. This was primarily funded by operating activities. Accounts receivable increased 
as a result of higher revenues during the month ended December 31, 2016 as compared to the same period in 2015, 
resulting primarily from an increase in transaction volume.

• 

In November 2016, we entered into three forward-fixed interest rate swap agreements to manage the interest rate risk 
associated with our outstanding variable-interest rate borrowings. Commencing January 2017, the Company receives 
variable interest of 1-month LIBOR under these swaps and pays fixed rates between 0.896% to 1.125%, reducing a portion 
of the variability of the future interest payments associated with $800 million of our borrowings.

•  During 2016, cash outflows from capital additions totaled $61.8 million, primarily related to the development of internal-

use software as we expand globally and provide competitive products and services to our customers.

2015 Highlights

•  During 2015, cash provided by operating activities was primarily provided by a decrease in accounts receivable, net of 
the accounts receivable balances acquired with our acquisitions, net income, and depreciation and amortization expense. 
Accounts receivable decreased in 2015 over 2014 as a result of decreases in fuel prices.

•  On November 18, 2015, we acquired Benaissance for approximately $80.7 million. The transaction was financed through 

the Company’s cash on hand and existing credit facility. 

•  On August 31, 2015, we acquired the remaining 49 percent ownership in UNIK, that we did not previously own, for 
approximately $46 million. The transaction was financed through the Company’s cash on hand and existing credit facility. 

•  On January 7, 2015, we sold our operations of rapid! PayCard for $20.0 million, which resulted in a pre-tax gain of $1.2 

million.

•  During 2015, we incurred restructuring charges of $9.0 million, of which approximately $1.4 million was paid during 

the year. These expenses consist of employee termination benefits and third party service fees. 

•  During 2015, we had approximately $63 million of capital expenditures. A significant portion of our capital expenditures 
are for the development of internal-use computer software primarily to enhance product features and functionality in the 
United  States  and  the  development  of  our  global  fleet  platform.  Our  capital  spending  is  financed  primarily  through 
internally generated funds.

Liquidity

General

In general, our trade receivables provide for payment terms of 30 days or less. Receivables not paid within the terms of 
the customer agreement are generally subject to late fees based upon the outstanding customer receivable balance. Beginning in 
the first quarter of 2015, we began to extend revolving credit to certain customers with respect to small fleet receivables. These 
accounts are also subject to late fees and balances that are not paid in full are subject to interest charges based on a revolving 
balance. As of December 31, 2017 and 2016, we had approximately $12.2 million and $3.4 million, respectively, of receivables 
with revolving credit.

At  December 31,  2017,  approximately  95  percent  of  the  outstanding  balance  of  $2.7  billion  of  total  trade  accounts 
receivable was 29 days or less past due and approximately 97 percent of the outstanding balance of total trade accounts receivable 
was 59 days or less past due. The outstanding balance is made up of receivables from a wide range of industries. No one customer 
represented 10 percent of the outstanding receivables balance as of December 31, 2017. One customer represented 11 percent of 
the outstanding receivables balance as of December 31, 2016.

Our short-term cash requirements consist primarily of funding the working capital needs of our business, payments on 
maturities and withdrawals of brokered deposits and borrowed federal funds, required capital expenditures, repayments on our 
credit facility, interest payments on our credit facility and other operating expenses. WEX Bank can fund our short-term domestic 
cash requirements through the issuance of brokered deposits and borrowed federal funds. Any remaining cash needs are primarily 
funded through operations. Our long-term cash requirements consist primarily of amounts owed on our 2016 Credit Agreement 
and Notes, amounts due to Wyndham Worldwide Corporation as part of our tax receivable agreement and various facilities lease 
agreements.

Undistributed earnings of certain foreign subsidiaries of the Company amounted to an estimated $58.7 million and $25.8 
million at December 31, 2017 and 2016, respectively. These earnings are considered to be indefinitely reinvested. As discussed 
in Item 8 - Note 14, Income Taxes, the United States enacted the 2017 Tax Act in December 2017, which impacted undistributed 
earnings, among other things. The 2017 Tax Act imposes a one time “transition tax” on foreign undistributed earnings, which will 
be paid with our 2017 U.S. Income Tax Return. To determine the amount of the transition tax, the Company must determine, in 
addition to other factors, the amount of post-1986 earnings and profits of the relevant foreign subsidiaries, as well as the amount 
of non-U.S. income taxes paid on such earnings. The Company is able to make a reasonable estimate of the transition tax and 
recorded a provisional transition tax obligation of $9.1 million. However, the Company is continuing to gather additional information 
to more precisely compute the amount of the transition tax. Upon distribution of these earnings in the form of dividends or otherwise, 
the Company would be subject to withholding taxes payable to the various foreign countries, but would have no further federal 
income tax liability, except for the difference in the provisional and actual tax. The Company’s primary tax jurisdictions are the 
United States, Australia and the United Kingdom.

Earnings outside of the United States are accompanied by certain financial risks, such as changes in foreign currency 
exchange rates. Changes in foreign currency exchange rates may reduce the reported value of our foreign currency revenues, net 
of expenses, and cash flows. We cannot predict changes in currency exchange rates, the impact of exchange rate changes, nor the 
degree to which we will be able to manage the impact of currency exchange rate changes.

Deposits and Borrowed Federal Funds

WEX Bank issues certificates of deposit in various maturities ranging between 3 month and three years, with interest 
rates ranging from 1.00 percent to 2.15 percent as of December 31, 2017, as compared to interest rates ranging from 0.65 percent
to 1.35 percent as of December 31, 2016. 

As of December 31, 2017, we had approximately $937.7 million of certificates of deposit outstanding at a weighted 
average interest rate of 1.51 percent, compared to $725.6 million of certificates of deposit outstanding at a weighted average interest 
rate of 0.96 percent as of December 31, 2016.  

WEX Bank also issues interest-bearing money market deposits with variable interest rates ranging from 1.24 percent to 
1.55 percent as of December 31, 2017, as compared to variable interest rates ranging from 0.48 percent to 0.87 percent as of 
December 31, 2016. 

As of December 31, 2017, we had approximately $285.9 million of brokered money market deposits outstanding at a 
weighted average interest rate of 1.49 percent, compared to $325.5 million of brokered money market deposits at a weighted 
average interest rate of 0.76 percent as of December 31, 2016.

52

 
 
 
 
 
 
 
 
 
Table of Contents

WEX Bank may issue brokered deposits without limitation, subject to FDIC rules governing minimum financial ratios, 
which include risk-based asset and capital requirements. As of December 31, 2017, all brokered deposits were in denominations 
of $250,000 or less, corresponding to FDIC deposit insurance limits. Interest-bearing money market funds may be withdrawn at 
any time. We believe that our brokered deposits are paying competitive yields and that there continues to be consumer demand 
for these instruments.

We also carry non-interest bearing deposits that are required for certain customers as collateral for their credit accounts. 

We had $70.2 million and $67.8 million of these deposits on hand at December 31, 2017 and 2016, respectively.

WEX Bank also borrows from lines of credit on a federal funds rate basis to supplement the financing of our accounts 
receivable. Our federal funds lines of credit were $400.0 million and $250.0 million as of December 31, 2017 and 2016 respectively, 
with no outstanding balance as of December 31, 2017.

2016 Credit Agreement

On July 1, 2016, we entered into the 2016 Credit Agreement in order to permit the additional financing necessary to 
facilitate the EFS acquisition. The 2016 Credit Agreement provided for a tranche A term loan facility in an original principal 
amount equal to $455 million, a tranche B term loan facility in an original principal amount equal to $1,200 million, and a $470 
million secured revolving credit facility, with a $250 million sublimit for letters of credit and a $20 million sublimit for swingline 
loans.

Incremental loans of up to the greater of $375 million (plus the amount of certain prepayments) and an unlimited amount 
subject to satisfaction of a consolidated leverage ratio test could be made available under the 2016 Credit Agreement upon the 
request of the Company, subject to specified terms and conditions, including receipt of lender commitments. Effective July 3, 
2017, the Company entered into a First Amendment to the 2016 Credit Agreement, which repriced the secured term loans under 
the 2016 Credit Agreement. The consolidated leverage ratio as defined in the 2016 Credit Agreement (i.e. consolidated funded 
indebtedness to consolidated EBITDA), was also modified for purposes of calculating the interest rate margin for tranche A term 
loans and revolving loans and determining compliance with the financial covenant by allowing the Company to exclude up to $75 
million of certain corporate cash balances for purposes of determining consolidated funded indebtedness. Effective October 30, 
2017, the Company entered into a Second Amendment to the 2016 Credit Agreement, which added $100 million of capacity to its 
revolving line of credit to provide additional liquidity and flexibility during 2017. Effective January 17, 2018, the Company entered 
into a Third Amendment to the 2016 Credit Agreement, which further repriced the tranche B term loans under the 2016 Credit 
Agreement, increased the outstanding amounts on these tranche B term loans from $1.182 billion to $1.335 billion, and made 
certain other changes to the 2016 Credit Agreement, including increasing the maximum consolidated leverage ratio for the period 
of December 31, 2018 through September 30, 2019 and upon the occurrence of an acquisition meeting certain specified criteria, 
permitting the incurrence of unsecured indebtedness as long as the Company is in pro forma compliance with the financial covenants 
and resetting and amending the test for incremental loans.

Proceeds from the 2016 Credit Agreement were used to pay the cash portion of the purchase price for the EFS acquisition, 
repay amounts outstanding under the 2014 Credit Agreement (which was superseded by the 2016 Credit Agreement), and pay 
related fees, expenses and other transaction costs, as well as for working capital and other general corporate purposes.

Our credit agreements contain various financial covenants requiring us to maintain certain financial ratios. In addition to 
the financial covenants, the credit agreements contain various customary restrictive covenants including restrictions in certain 
situations on the payment of dividends. WEX Bank is not subject to certain of these restrictions. We were in compliance with all 
material covenants and restrictions at December 31, 2017. 

As of December 31, 2017, we had $136.5 million of outstanding borrowings against our $570.0 million revolving credit 
facility, which terminates in July of 2021. The combined outstanding debt under our tranche A term loan facility, which expires 
in July of 2021, and our tranche B term loan facility, which expires in July of 2023, totaled $1.6 billion at December 31, 2017. As 
of December 31, 2017, amounts outstanding under the 2016 Credit Agreement bore a weighted average effective interest rate of 
4.2%. 

See Item 8 - Note 13, Financing Debt for further information regarding interest rates, voluntary prepayments rights and 

principal payments required under our 2014 and 2016 Credit Agreements.

Ticking Fees

In January 2016, we began to incur ticking fees for the debt financing commitment associated with the 2016 Credit 
Agreement in anticipation of the then pending acquisition of EFS. Through June 30, 2016, we recorded $30 million of ticking 
fees, which is included in financing interest expense. These ticking fees were calculated based on the financing commitment of 

53

 
 
 
 
 
 
 
 
 
Table of Contents

an aggregate principal amount of $2.125 billion that remained in place until the closing of the EFS acquisition on July 1, 2016. 
The total amount of ticking fees paid at the closing of the EFS acquisition was $22.2 million. The excess ticking fees of $7.9 
million were netted against the net debt issuance costs related to the 2016 Credit Agreement and will be amortized over the 2016 
Credit Agreement's terms using the effective interest method for the tranche A and B term loans and the revolver. 

Notes Outstanding

On January 30, 2013, the Company completed a $400 million offering in aggregate principal amount of its 4.750 percent 
senior notes due 2023 (the “Notes”) at an issue price of 100.0 percent of the principal amount, plus accrued interest, from January 30, 
2013. Proceeds from the Notes were used to pay down the entire outstanding balance of the revolver portion of our 2013 Credit 
Agreement. The remaining proceeds are available for working capital purposes, acquisitions, payment of dividends and other 
restricted payments, refinancing of indebtedness, and other general corporate purposes.

WEX Latin America Debt

WEX  Latin America  had  debt  of  approximately  $9.7  million  and  $30.8  million  as  of  December 31,  2017  and  2016, 
respectively. This is comprised of credit facilities held in Brazil and loan arrangements related to our accounts receivable, with 
various maturity dates. The average interest rate was 21.2 percent and 19.7 percent for the years ended December 31, 2017 and 
2016, respectively. This debt is classified in Other debt on the Company’s consolidated balance sheets for the periods presented. 

Participation Debt

WEX Bank maintains agreements with third-party banks to fund customer balances that exceed WEX Bank's lending 
limit to an individual customer. During the year ended December 31, 2017, the Company increased the funding capacity of these 
arrangements by $90.0 million to $185.0 million. Associated borrowings carry a variable interest rate of 1 month to 3 month LIBOR 
plus a margin of 225 basis points. The balance of the debt was approximately $185.0 million and $95.0 million at December 31, 
2017 and 2016, respectively, and was secured by an interest in the underlying customer receivables. The balance will fluctuate on 
a daily basis based on customer funding needs. The commitment will mature in amounts of $85.0 million and $50.0 million on 
May 30, 2018 and December 31, 2021, respectively, with the remaining $50 million maturing on demand. 

Australian Securitization Facility

During the second quarter of 2017, the Company extended an existing securitized debt agreement with the Bank of Tokyo-
Mitsubishi UFJ, Ltd. through April 2018. Under the terms of the agreement, each month, on a revolving basis, the Company sells 
certain of its Australian receivables to the Company's Australian Securitization Subsidiary. The Australian Securitization Subsidiary, 
in turn, uses the receivables as collateral to issue asset-backed commercial paper (“securitized debt”) for approximately 85 percent
of the securitized receivables. The amount collected on the securitized receivables is restricted to pay the securitized debt and is 
not available for general corporate purposes. 

The Company pays a variable interest rate on the outstanding balance of the securitized debt, based on the Australian 
Bank Bill Rate plus an applicable margin. The interest rate was 2.53 percent and 2.65 percent as of December 31, 2017 and 2016, 
respectively. The Company had securitized debt under this facility of approximately $90,000 and $78,600 as of December 31, 
2017 and 2016, respectively. 

European Securitization Facility

On April 7, 2016, the Company entered into a five year securitized debt agreement with the Bank of Tokyo-Mitsubishi 
UFJ, Ltd. Under the terms of the agreement, the Company sells certain of its receivables from selected European countries to our 
European Securitization Subsidiary. The European Securitization Subsidiary, in turn, uses the receivables as collateral to issue 
securitized debt. The amount collected on the securitized receivables is restricted to pay the securitized debt and is not available 
for general corporate purposes. The amounts of receivables to be securitized under this agreement will be determined by management 
on a monthly basis. The Company had $17.9 million of securitized debt under this facility as of December 31, 2017 at an interest 
rate of 1.11 percent and $5.7 million of securitized debt under this facility as of December 31, 2016 at an interest rate of 0.95 
percent.

WEX Latin America Securitization Facility

During the second quarter of 2017, WEX Latin America entered into a securitized debt agreement to sell certain unsecured 
receivables associated with our salary payment card product to an investment fund managed by an unrelated third-party financial 
institution. Under the terms of the agreement, the investment fund's purchase price incorporates a discount relative to the face 
value of the transferred receivables. Additionally, the investment fund compensates WEX Latin America for continuing to service 
these receivables through their duration, which on average is less than six months.

During 2017, WEX Latin America securitized approximately $49.1 million of receivables to the investment fund for cash 
proceeds  of  approximately  $43.8  million.  This  $5.3  million  discount  is  recognized  as  operating  interest  in  the  Company's 
consolidated statements of income using the effective interest method over the weighted average term of the salary advances. As 
of December 31, 2017, the Company had approximately $19.0 million of securitized debt under this facility.

WEX Europe Services Accounts Receivable Factoring

During the first quarter of 2017, WEX Europe Services entered into a factoring arrangement with an unrelated third-party 
financial institution (the "Purchasing Bank”) to sell certain of its accounts receivable in order to accelerate the collection of the 
Company's cash and reduce internal costs, thereby improving liquidity. Under this arrangement, the Purchasing Bank establishes 
a credit limit for each customer account. The factored receivables are without recourse to the extent that the customer balances 
are maintained at or below the established credit limit. For customer receivable balances in excess of the Purchasing Bank's credit 
limit, the Company maintains the risk of default. The Company obtained a true sale opinion from an independent attorney, which 
states that the factoring agreement creates a sale of receivables under local law for amounts transferred both below and above the 
established credit limits. Additionally, there are no indications of the Company's continuing involvement in the factored receivables. 
As a result, the Purchasing Bank is deemed the purchaser of these receivables and is entitled to enforce payment of these amounts 
from the debtor. 

This factoring arrangement is accounted for as a sale and accordingly the Company records the receivables sold as a 
reduction of accounts receivable and proceeds as cash provided by operating activities. The Company sold approximately $574.4 
million of receivables under this arrangement during year ended December 31, 2017. Charge-backs on balances in excess of the 
credit limit during the year ended December 31, 2017 were insignificant.

Other Liquidity Matters

On July 1, 2016, the Company completed the acquisition of EFS for approximately $1.2 billion in cash and 4 million

shares of its common stock.

At December 31, 2017, we had variable-rate borrowings of $1.7 billion under our 2016 Credit Agreement. We periodically 
review our projected borrowings under our 2016 Credit Agreement and the current interest rate environment in order to ascertain 
whether interest rate swaps should be used to reduce our exposure to interest rate volatility. During 2016 and 2017, we entered 
into five interest rate swap contracts that mature between December 2018 and December 2022. Collectively, these derivative 
contracts are intended to fix the future interest payments associated with $1.3 billion of our variable rate borrowings at between  
0.896% to 2.212%. See Item 8 – Note 11, Derivative Instruments for more information. See Note 17, Fair Value for more information.

Our long-term cash requirements consist primarily of amounts owed on our 2016 Credit Agreement, our outstanding 
Notes, amounts due to Wyndham Worldwide Corporation (see Note 15, Tax Receivable Agreement, in Part II, Item 8) as part of 
our tax receivable agreement, and various facilities lease agreements. 

As of December 31, 2017, we also had $27.5 million in letters of credit outstanding. At December 31, 2017, we had 
$1,707.1 million of borrowed funds, and $406.0 million available under the 2016 Credit Agreement, subject to the covenants as 
described above. 

We currently have authorization from our Board to purchase up to $150 million of our common stock until September 
2021, which is entirely unused as of December 31, 2017. The program is funded either through our future cash flows or through 
borrowings on our 2016 Credit Agreement. Share repurchases are made on the open market and may be commenced or suspended 
at any time. The Company’s management, based on its evaluation of market and economic conditions and other factors, determines 
the timing and number of shares repurchased. 

We discuss our hedging strategies relative to commodity and interest rate risk in Item 7A below. Our fuel price derivatives 
were entered into to mitigate the volatility that domestic fuel prices introduce to our revenue streams. These derivatives restricted 
a portion of our fuel price exposure to a collar range, established at the time the fuel price derivatives were purchased. During the 
fourth quarter of 2014, we suspended purchases under our fuel derivatives program due to unusually low prices in the commodities 
market. After the first quarter of 2016, we were no longer hedged for changes in fuel prices. Management will continue to monitor 
the fuel price market and evaluate our alternatives as it relates to this hedging program. 

Management believes that we can adequately fund our cash needs for at least the next 12 months.

(a) Operating leases – We lease office space, office equipment and computer equipment under long-term operating leases, which 
are recorded in occupancy and equipment or technology leasing and support. See Item 8 - Note 18, Commitments and Contingencies
for more information.

(b) Interest payments on term loans – Interest payments are based on effective rates and credit spreads in effect as of December 31, 
2017. See Item 8 - Note 13, Financing Debt for more information.

(c) Other debt – This amount consists of participation debt at WEX Bank and debt balances at one of the Company's subsidiaries. 
Interest payments due were not included as the amount was not material.

(d) Securitization facility – Interest payments due on the securitization facility are not included as the amount was not material.

(e) Minimum volume purchase commitments – One of the Company's subsidiaries is required to purchase a minimum amount of 
fuel from their suppliers on an annual basis. If the minimum requirement is not fulfilled, they are subject to penalties based on the 
amount of spend below the minimum annual volume commitment. Starting in 2020, annual volume commitments reset based on 
prior year volume purchased. The table above represents the Company's annual penalty assuming we purchase no fuel under these 
commitments after December 31, 2017.

(f) Tax receivable agreement – As a consequence of the Company’s separation from its former parent company in 2005, the tax 
basis of the Company’s net tangible and intangible assets increased, reducing the amount of tax that the Company would pay in 
the future to the extent the Company generated taxable income in sufficient amounts. The Company is contractually obligated to 
remit a portion of any such cash savings to a third party. The estimate of payments owed is reflected as Amounts due under tax 
receivable agreement on the consolidated balance sheets. See Item 8 - Note 15, Tax Receivable Agreement for more information.

(g) Other  –    This  amount  is  comprised  of  future  payments  due  for  contractually  obligated  outsourced  information  technology 
services.

Uncertain tax liabilities – The Company has excluded $5,037 in gross unrecognized tax benefits as of December 31, 2017 from 
the table above due to the uncertainty about the timing of payments to the taxing authority.

Off-balance Sheet Arrangements

In addition to the operating leases included in the table above, we have the following off-balance sheet arrangements as 

of December 31, 2017:

•  Extension of credit to customers – We have entered into commitments to extend credit in the ordinary course of business. 
We had approximately $6.3 billion of unused commitments to extend credit at December 31, 2017, as part of established 
customer agreements. These amounts may increase or decrease during 2018 as we increase or decrease credit to customers, 
subject to appropriate credit reviews, as part of our lending product agreements. Many of these commitments are not 
expected to be utilized; therefore, we do not believe total unused credit available to customers and customers of strategic 
relationships represents future cash requirements. We can adjust most of our customers’ credit lines at our discretion at 
any time. We believe that we can adequately fund actual cash requirements related to these credit commitments through 
the issuance of certificates of deposit, borrowed federal funds and other debt facilities.

• 

Letters of credit – As of December 31, 2017, we had $27.5 million outstanding in irrevocable letters of credit issued by 
us in favor of third-party beneficiaries, primarily related to facility lease agreements and virtual card and fuel payment 
processing activity at our foreign subsidiaries. These irrevocable letters of credit are unsecured and are renewed on an 
annual basis unless the Company chooses not to renew them. 

•  Accounts receivable factoring – See Item 8 - Note 12, Off-Balance Sheet Arrangements for further information.

Application of Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial 
statements, which have been prepared in accordance with Generally Accepted Accounting Principles. Preparation of these financial 
statements requires us to make estimates and judgments that affect reported amounts of assets and liabilities, revenue and expenses 
and  related  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  our  financial  statements. We  continually  evaluate  our 
judgments and estimates in determination of our financial condition and operating results. We base our estimates on historical 
experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form 
the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. 
Estimates are based on information available as of the date of the financial statements and, accordingly, actual results could differ 
from these estimates, sometimes materially. Critical accounting policies and estimates are defined as those that are both most 
important to the portrayal of our financial condition and operating results and require management’s most subjective judgments. 
Our consolidated financial statements are based on the selection and application of critical accounting policies and estimates, the 
most significant of which are included in the tables below.

Effect if Actual Results Differ from
Assumptions

In preparing the financial statements, 
management must make estimates related to 
the contractual terms, customer performance 
and sales volume to determine the total 
amounts recorded as deductions, such as 
rebates and incentives, from revenue. 
Management also considers historical results 
in making such estimates. The actual amounts 
ultimately paid to the customer may be 
different from our estimates. Such differences 
are recorded once they have been determined 
and have historically not been significant.

Revenue Recognition

Description                                                     

   Assumptions/Approach Used

The Company generally records revenue net of 
costs based on the following criteria: (i) the 
Company is not the primary obligor in the 
arrangement; (ii) the Company has no 
inventory risk; (iii) the Company does not have 
reasonable latitude with respect to establishing 
the price for the product; (iv) the Company 
does not make any changes to the product or 
have any involvement in the product 
specifications; and (v) the amount the 
Company earns for its services is fixed, within 
a limited range. 

The Company enters into contracts with certain 
large customers or strategic relationships that 
provide for fee rebates tied to performance 
milestones. Rebates are recorded as a reduction 
in revenue in the same period that revenue is 
earned or performance occurs. Rebates and 
incentives are calculated based on estimated 
performance and the terms of the related 
business agreements.

Service related revenues are recognized in the 
period that the work is performed.

The Company recognizes SaaS based service 
fees in the healthcare market for the per-
participant per-month fee which is recognized 
on a monthly basis subsequent to billing being 
completed. Interchange fees are recorded as 
received and ancillary service revenue is 
recognized when the related services have 
been provided. 

The majority of the Company’s revenues are 
comprised of transaction-based fees, which are 
generally calculated based on measures such as: 
(i) percentage of dollar value of volume processed; 
(ii) number of transactions processed; or (iii) some 
combination thereof.

In Europe, our Fleet Solutions payment processing 
revenue is specifically derived from the difference 
between the negotiated price of the fuel from the 
supplier and the agreed upon price paid by the 
fleets.  

Interchange income is earned from the Company’s 
suite of card products. Interchange income is a fee 
paid by a merchant bank to the card-issuing bank 
through the interchange network. Interchange fees 
are set by the credit card providers. The Company 
recognizes interchange income as it is earned. 

The Company assesses fees for providing ancillary 
services, such as information products and services, 
SaaS based fees, professional services and 
marketing services. Other revenues also include 
cross-border fees, fees for overnight shipping, 
certain customized electronic reporting and 
customer contact services provided on behalf of 
certain of the Company’s customers. 

The Company has entered into agreements with 
major oil companies, fuel retailers and vehicle 
maintenance providers which provide products and/
or services to the Company’s customers. These 
agreements specify that a transaction is deemed to 
be captured when the Company has validated that 
the transaction has no errors and has accepted and 
posted the data to the Company’s records. The 
Company recognizes revenues when persuasive 
evidence of an arrangement exists, the products and 
services have been provided to the client, the sales 
price is fixed or determinable and collectability is 
reasonably assured.

Reserve for Credit Losses

Description                                                     

   Assumptions/Approach Used

The reserve for losses relating to accounts
receivable represents management’s estimate of the
losses inherent in the Company’s outstanding
portfolio of receivables, including losses from
skimming fraud. The reserve for credit losses
reduces the Company’s accounts receivable
balances as reported in its financial statements to
the net realizable value.

Management has consistently considered its 
portfolio of charge card receivables as a large 
group of smaller balance accounts that it has 
collectively evaluated for impairment. 
Reserves for losses on these receivables are 
primarily based on a model that analyzes 
specific portfolio statistics, including average 
charge-off rates for various stages of 
receivable aging (including: current, 30 days, 
60 days, 90 days) over historical periods 
including average bankruptcy and recovery 
rates. Receivables are generally written off 
when they are 150 days past due or declaration 
of bankruptcy by the customer.

The reserve reflects management’s judgment 
regarding overall reserve adequacy. 
Management considers whether to adjust the 
reserve that is calculated by the analytic model 
based on other factors, such as the actual 
charge-offs for the preceding reporting periods, 
expected charge-offs and recoveries for the 
subsequent reporting periods, a review of 
accounts receivable balances which become 
past due, changes in customer payment 
patterns, known fraudulent activity in the 
portfolio, as well as leading economic and 
market indicators.

Effect if Actual Results Differ from
Assumptions

To the extent historical credit experience is 
not indicative of future performance, actual 
loss experience could differ significantly 
from management’s judgments and 
expectations, resulting in either higher or 
lower future provisions for credit losses, as 
applicable. As of December 31, 2017, we 
have estimated a reserve for credit losses 
which is 1.18 percent of the total gross 
accounts receivable balance.

An increase or decrease to this reserve by 
0.5 percent would increase or decrease the 
provision for credit losses for the year by 
$12.8 million. As of December 31, 2017, 
2016 and 2015, our reserve for credit losses 
in an annual period has ranged from 0.91 
percent to 1.18 percent of the total receivable 
balance.

59

  
  
 
  
 
Effect if Actual Results Differ from
Assumptions

We review the carrying values of the 
unamortizing and amortizing assets for 
impairment annually and whenever events or 
changes in business circumstances indicate 
that the carrying amount of an asset may not 
be recoverable. Such circumstances would 
include, but are not limited to, a significant 
decrease in the perceived market price of the 
intangible, a significant adverse change in the 
way the asset is being used, or a history of 
operating or cash flow losses associated with 
the use of the intangible.

Our goodwill resides in multiple reporting 
units. The profitability of individual reporting 
units may suffer periodically from downturns 
in customer demand or other economic 
factors. Individual reporting units may be 
more impacted than the Company as a whole. 
Specifically, during times of economic 
slowdown, our customers may reduce their 
expenditures. As a result, demand for the 
services of one or more of the reporting units 
could decline which could adversely affect 
our operations, cash flow, and liquidity and 
could result in an impairment of goodwill or 
intangible assets.

As of December 31, 2017, the Company had 
an aggregate of approximately $3,030 million 
on its consolidated balance sheet related to 
goodwill and intangible assets of acquired 
entities. The results of our goodwill 
impairment test indicate an excess of 
estimated fair value over the carrying amount 
for each of our reporting units by a range of 
approximately $90 million to $2.5 billion. 
Although no reporting units are deemed at 
risk of impairment as of December 31, 2017, 
the potential for impairment exists in the 
future should actual results deteriorate versus 
our current expectations.

Business Combinations, Acquired Intangible Assets and Goodwill

Description                                                     

Assumptions/Approach Used

Business combinations are accounted for at fair 
value. The accounting for business combinations 
requires estimates and judgment as to expectations 
for future cash flows of the acquired business, and 
the allocation of those cash flows to identifiable 
intangible assets, in determining the estimated fair 
value for assets and liabilities acquired.

The fair values assigned to tangible and
intangible assets acquired and liabilities
assumed are based on management’s estimates
and assumptions, as well as other information
compiled by management, including valuations
that utilize customary valuation procedures and
techniques.

Goodwill is comprised of the cost of business 
acquisitions in excess of the fair value assigned to 
the net tangible and identifiable intangible assets 
acquired. Goodwill is not amortized but is 
reviewed for impairment annually, or when events 
or changes in the business environment indicate 
that the carrying value of the reporting unit may 
exceed its fair value. Acquired intangible assets 
result from the allocation of the cost of an 
acquisition. These acquired intangibles include 
assets that amortize, primarily software and 
customer relationships, and those that do not 
amortize, specifically trademarks and certain trade 
names. The annual review of goodwill and non-
amortizing intangibles values is performed as of 
October 1 of each year.

In the fourth quarter of 2017, we elected to
bypass the qualitative approach and instead
proceeded directly to step one of the two-step
impairment test to assess the fair value of all of
our reporting units. For the reporting units that
carry goodwill balances, our impairment test
consists of a comparison of each reporting
unit’s carrying value to its estimated fair value.
A reporting unit, for the purpose of the
impairment test, is one level below the
operating segment level. We have three
reporting segments that are further broken into
several reporting units for the impairment
review. The estimated fair value of a reporting
unit is primarily based on discounted estimated
future cash flows. An appropriate discount rate
is used, as well as risk premium for specific
business units, based on the Company’s cost of
capital or reporting unit-specific economic
factors. We generally validate the model
through a reconciliation of the fair value of all
our reporting units to our overall market
capitalization. The assumptions used to
estimate the discounted cash flows are based
on our best estimates about payment
processing fees/interchange rates, sales
volumes, costs (including fuel prices), future
growth rates, working capital needs, capital
expenditures and market conditions over an
estimate of the remaining operating period at
the reporting unit level. The discount rate at
each reporting unit is based on the weighted
average cost of capital that is determined by
evaluating the risk free rate of return, cost of
debt, and expected equity premiums.

Non-goodwill intangible assets are considered
non-recoverable if the carrying amount
exceeds the sum of undiscounted cash flows
expected to result from the use of the assets.
The recoverability test is based on
management’s intended use of the assets. If the
asset fails the recoverability test, impairment is
measured as the amount by which the carrying
amount of the asset group exceeds its fair
value. Fair value measurements under FASB
Accounting Standards Codification (“ASC”)
820 - Fair Value Measurements and
Disclosures, are based on the assumptions of
market participants. When determining the fair
value of the asset group, entities must consider
the highest and best use of the assets from a
market-participant perspective.

Income Taxes

Description                                                     

Assumptions/Approach Used

In preparing the consolidated financial statements, 
we calculate income tax expense (benefit) based on 
our interpretation of the tax laws in the various 
jurisdictions where we conduct business. This 
requires us to estimate current tax obligations and 
to assess temporary differences between the 
financial statement carrying amounts and the tax 
bases of assets and liabilities. These differences 
result in deferred tax assets and liabilities, the net 
amount of which we show as a line item on the 
consolidated balance sheet. All or a portion of the 
benefit of income tax positions is recognized only 
when we have made a determination that it is more 
likely than not that the tax position will be 
sustained upon examination, based upon the 
technical merits of the position and other factors. 
For tax positions that are determined as more likely 
than not to be sustained upon examination, the tax 
benefit recognized is the largest amount of benefit 
that is greater than 50% likely of being realized 
upon ultimate settlement. We must also assess the 
likelihood that the deferred tax assets will be 
realized. 

To the extent we believe that realization is not more 
likely than not, we establish a valuation allowance. 
When we establish a valuation allowance or 
increase this allowance, we generally record a 
corresponding income tax expense in the 
consolidated statement of income in the period of 
the change. Conversely, to the extent circumstances 
indicate that realization is more likely than not, the 
valuation allowance is decreased to the amount 
realizable, which generates an income tax benefit. 

Management must make judgments to 
determine income tax expense (benefit), 
deferred tax assets and liabilities and any 
valuation allowance to be recorded against 
deferred tax assets. During the ordinary course 
of business, there are many transactions and 
calculations for which the ultimate tax 
determination is uncertain. Changes in our 
estimates occur periodically due to changes in 
tax rates, changes in business operations, 
implementation of tax planning strategies, the 
expiration of relevant statutes of limitations, 
resolution with taxing authorities of uncertain 
tax positions and newly enacted statutory, 
judicial and regulatory guidance. We record a 
valuation allowance to reduce deferred tax 
assets to the amount that is more likely than 
not to be realized. 

Significant judgment is required in 
determining valuation allowances. In 
evaluating the ability to recover deferred tax 
assets, we consider all available positive and 
negative evidence including past operating 
results, the existence of cumulative losses in 
the most recent years, forecasted earnings, 
future taxable income, and prudent and 
feasible tax planning strategies. In establishing 
a liability for unrecognized tax benefits, 
assumptions are made in determining whether, 
and to what extent, a tax position may be 
sustained.  It requires significant management 
judgment regarding applicable statutes and 
their related interpretation as they apply to our 
particular facts and circumstances. 

Effect if Actual Results Differ from
Assumptions

Although we believe that our income tax 
related judgments and estimates are 
reasonable, it is possible that our actual 
results could be different than what we 
expected, and we may be exposed to a 
material change in our total income tax 
expense, tax-related balances, or valuation 
allowances. Upon income tax audit, any 
unfavorable tax settlement may require use of 
our cash and result in an increase in our 
effective tax rate in the period of settlement. 
A favorable tax settlement could be 
recognized as a reduction in our effective tax 
rate in the period of settlement.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risk related to interest rates, foreign currency exchange rates and commodity prices. 

From time to time, the Company enters into derivative instrument arrangements to manage these risks.

Interest Rate Risk

2016 Credit Agreement

At December 31, 2017, we had variable-rate borrowings of $1.7 billion under our 2016 Credit Agreement. We periodically 
review our projected borrowings under our 2016 Credit Agreement and the current interest rate environment in order to ascertain 
whether interest rate swaps should be used to reduce our exposure to interest rate volatility. During 2016 and 2017, we entered 
into five interest rate swap contracts that mature between December 2018 and December 2022. Collectively, these derivative 
contracts are intended to fix the future interest payments associated with $1.3 billion of our variable rate borrowings at between  
0.896% to 2.212%. See Item 8 – Note 11, Derivative Instruments for more information.

At December 31, 2017, WEX Bank had deposits (includes certificates of deposits, interest bearing money market deposits 
and participation debt) outstanding of $1.2 billion. The deposits are generally short-term in nature. Upon maturity, the deposits 
will likely be replaced by issuing new deposits to the extent they are needed. 

Sensitivity Analysis

The following table presents a sensitivity analysis of the impact of changes in interest rates on our deposits and corporate 
debt, assuming amounts outstanding, the notional amounts of our interest rate swap agreements, and certificate of deposit maturities 
in place as of December 31, 2017 remain constant. Actual results may differ materially.

Our exposure to foreign currency fluctuation is due to our financial statements being presented in U.S. dollars and our 
foreign subsidiaries transacting in currencies other than the U.S. dollar, which results in gains and losses that are reflected in our 
consolidated statements of operations. We currently do not utilize hedging instruments to mitigate these risks. However, growth 
in our international operations increases this exposure and we may initiate strategies to hedge certain foreign currency risks in the 
future.

Commodity Price Risk

We previously used derivative instruments to manage the impact of volatility in North American fuel prices on our earnings. 
We entered into put and call option contracts (“Options”) based on the wholesale price of unleaded gasoline and retail price of 
diesel fuel, which settled on a monthly basis through the first quarter of 2016. The Options were intended to lock in a range of 
prices during any given quarter on a portion of our forecasted earnings subject to fuel price variations. During the fourth quarter 
of 2014, we suspended purchases under our fuel derivatives program due to unusually low prices in the commodities market. After 
the first quarter of 2016, we were no longer hedged for changes in fuel prices. Management will continue to monitor the fuel price 
market and evaluate its alternatives as it relates to this hedging program.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of WEX Inc.
South Portland, Maine

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of WEX Inc. and subsidiaries (the "Company”) as of December 
31, 2017 and 2016, the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows, 
for each of the three years in the period ended December 31, 2017, and the related notes (collectively referred to as the 
"financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of 
the Company as of 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 accounting principles generally accepted in the United States of 
America.

We have also 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 (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission and our report dated March 1, 2018, expressed an unqualified opinion on the Company's internal control over 
financial reporting. 

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.

2015,  include  the  accounts  of  the  Company  and  its  wholly  and  majority-owned  subsidiaries. All  intercompany  accounts  and 
transactions have been eliminated in consolidation.

The Company rounds amounts in the consolidated financial statements to thousands and calculates all percentages and 
per-share data from underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot, or recalculate based on 
reported numbers due to rounding. 

Use of Estimates and Assumptions

The Company prepares its consolidated financial statements in conformity with GAAP and with the Rules and Regulations 
of the SEC, specifically Regulation S-X and the instructions to Form 10-K. These principles require management to make estimates 
and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as 
of the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results could 
differ from those estimates and those differences may be material.

Cash and Cash Equivalents

Highly liquid investments with remaining maturities at the time of purchase of three months or less (that are readily 
convertible to cash) are considered to be cash equivalents and are stated at cost, which approximates fair value. Cash equivalents 
include federal funds sold, which are unsecured short-term investments entered into with financial institutions. 

Restricted Cash

Restricted cash represents funds collected from individuals or employers on behalf of our customers that are to be remitted 
to third parties or funds required to be maintained on hand under certain vendor agreements. This restricted cash, which is not 
available to fund the Company’s operations, totaled $18,866 and $22,412 as of December 31, 2017 and 2016, respectively, and is 
classified in other assets on the Company’s consolidated balance sheets. We maintain an offsetting liability against restricted cash 
collected and remitted on behalf of our customers.

Accounts Receivable, Net of Allowances

Accounts  receivable  is  stated  at  net  realizable  value. The  balance  includes  a  reserve  for  credit  losses  which  reflects 
management’s estimate of uncollectable balances resulting from credit and fraud losses. Management has consistently considered 
its portfolio of charge card receivables as a large group of smaller balance accounts that it has collectively evaluated for impairment. 
The reserve for credit losses is established based on the determination of the amount of expected credit losses inherent in the 
accounts receivable as of the reporting date. Management reviews delinquency reports, historical collection rates, changes in 
customer payment patterns, economic trends, geography and other information in order to make judgments as to probable credit 
losses. Management also uses historical charge off experience to determine the amount of losses inherent in accounts receivable 
at the reporting date. Assumptions regarding probable credit losses are reviewed periodically and may be impacted by actual 
performance of accounts receivable and changes in any of the factors discussed above. The balance also includes a reserve for 
waived finance fees, which is used to maintain customer goodwill and recorded against the late fee revenue recognized.

Available-for-sale Securities

The Company records certain investments as available-for-sale securities. Available-for-sale securities are carried at fair 
value, with unrealized gains and losses, net of tax, reported on the consolidated balance sheets in accumulated other comprehensive 
loss. Realized gains and losses and declines in fair value determined to be other-than-temporary are included in non-operating 
expenses. The cost basis of securities is based on the specific identification method. Interest and dividends earned on securities 
classified as available-for-sale are included in other revenue. Available-for-sale securities held by the Company were purchased 
and are held by WEX Bank in order to meet the requirements of the Community Reinvestment Act.

Derivatives

From time to time, the Company utilizes derivative instruments as part of its overall strategy to manage its exposure to 
fluctuations  in  fuel  prices  and  to  reduce  the  impact  of  interest  and  foreign  currency  exchange  rate  volatility. The  Company's  
derivative instruments are recorded at fair value on the consolidated balance sheets. The Company’s derivative instruments have 
not been designated as hedges; therefore, both realized and unrealized gains and losses are recognized in earnings. For the purposes 
of cash flow presentation, realized and unrealized gains or losses are included within cash flows from operating activities.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation. Replacements, renewals and improvements 
are capitalized and costs for repair and maintenance are expensed as incurred. Depreciation is primarily computed using the straight-
line method over the estimated useful lives shown below. 

Below are the estimated useful lives for assets placed in service during 2017 and beyond:

Furniture, fixtures and equipment

Internal-use computer software

Computer software
Leasehold improvements(a)

Estimated Useful Lives

3 to 5 years

1.5 to 7 years

3 years

up to 5 years

(a) Leasehold improvements are primarily depreciated using the straight-line method over the lesser of the useful life of the asset or the remaining lease term.

Capitalized Software

The Company develops software that is used to provide processing and information management services to customers. 
A significant portion of the Company’s capital expenditures is devoted to the development of such internal-use computer software. 
Costs incurred during the preliminary project stage are expensed as incurred. Software development costs are capitalized during 
the  application  development  stage.  Capitalization  begins  when  the  preliminary  project  stage  is  complete,  as  well  as  when 
management authorizes and commits to the funding of the project. Capitalization of costs ceases when the software is ready for 
its intended use. Costs related to maintenance of internal-use software are expensed as incurred. Software development costs are 
amortized using the straight-line method over the estimated useful life of the software.

Below are the amounts of internal-use software capitalized and amortized:

Amounts capitalized for internal-use computer software (including work-in-process)

Amounts expensed for amortization of internal-use computer software

The Company classifies intangible assets in the following three categories: (1) intangible assets with definite lives subject 
to amortization, (2) intangible assets with indefinite lives not subject to amortization and (3) goodwill. The Company tests intangible 
assets with definite lives for impairment if conditions exist that indicate the carrying value may not be recoverable. Such conditions 
may include a reduction in operating cash flow or a dramatic change in the manner in which the asset is intended to be used. The 
Company records an impairment charge when the carrying value of the definite-lived intangible asset is not recoverable from the 
undiscounted cash flows generated from the use of the asset.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

Intangible assets with indefinite lives and goodwill are not amortized. The Company tests these intangible assets and 
goodwill  for  impairment at  least  annually or  more  frequently if  facts or  circumstances indicate that  such  intangible assets  or 
goodwill might be impaired. All goodwill and intangible assets are assigned to reporting units, which are one level below the 
Company’s operating segments. The Company performs impairment tests at the reporting unit level. Such impairment tests include 
comparing the fair value of the respective reporting unit with its carrying value, including goodwill. The Company uses both 
discounted cash flow analyses and comparable company pricing multiples to determine the fair value of our reporting units. Such 
analyses are corroborated using market analytics. Certain assumptions are used in determining the fair value, including assumptions 
about future cash flows and terminal values. When appropriate, the Company considers the assumptions that it believes hypothetical 
marketplace participants would use in estimating future cash flows. In addition, an appropriate discount rate is used, based on the 
Company’s cost of capital or reporting unit-specific economic factors. When the fair value is less than the carrying value of the 
intangible assets or the reporting unit, the Company records an impairment charge to reduce the carrying value of the assets to the 
reporting unit's implied fair value. The Company's annual goodwill and intangible asset impairment tests performed as of October 
1, 2017, 2016 and 2015 did not identify any impairment. 

Intangible assets that are deemed to have definite lives are amortized over their useful lives, which is the period of time 
that the asset is expected to contribute directly or indirectly to future cash flows. The Company determines the useful lives of its 
identifiable intangible assets after considering the specific facts and circumstances related to each intangible asset. The factors 
that management considers when determining useful lives include the contractual term of agreements, the history of the asset, the 
Company’s long-term strategy for the use of the asset, any laws or other local regulations which could impact the useful life of 
the asset and other economic factors, including competition and specific market conditions. An evaluation of the remaining useful 
lives of the definite-lived intangible assets is performed periodically to determine if any change is warranted.

Impairment and Disposals of Assets

Long-lived assets are tested for impairment whenever facts or circumstances, such as a reduction in operating cash flow 
or a dramatic change in the manner the asset is intended to be used, indicate the carrying amount of the asset may not be recoverable. 
The Company compares the estimated undiscounted future cash flows associated with these assets or operations to their carrying 
value to determine if a write-down to fair value is required. 

During 2017, the Company impaired certain software currently under development for payment processing and prepaid 
services related to technology outsourcing as these items were determined to have no future benefit. See Note 22, Impairment and 
Restructuring Activities,  for  further  discussion.  The  Company  did  not  recognize  any  significant  impairment  expense  on  the 
Company’s assets during the years ended December 31, 2016 and 2015. Disposals in the ordinary course of business are recorded 
in occupancy and equipment in the consolidated statements of income.

Fair Value of Financial Instruments

The  Company  holds  mortgage-backed  securities,  fixed-income  securities,  derivatives  (see  Note  11,  Derivative 
Instruments) and certain other financial instruments that are carried at fair value. The Company determines fair value based upon 
quoted prices when available or through the use of alternative approaches, such as model pricing, when market quotes are not 
readily  accessible  or  available.  Various  factors  are  considered  in  determining  the  fair  value  of  the  Company’s  obligations, 
including: closing exchange or over-the-counter market price quotations; time value and volatility factors underlying options and 
derivatives; price activity for equivalent instruments; and the Company’s own-credit standing. 

These valuation techniques may be based upon observable and unobservable inputs. Observable inputs reflect market 
data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types 
of inputs create the following fair value hierarchy:

•  Level 1 – Quoted prices for identical instruments in active markets.

•  Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments 
in markets that are not active; and model-derived valuations whose inputs are observable or whose significant 
value drivers are observable.

•  Level 3 – Instruments whose significant value drivers are unobservable.

Assets  and  liabilities  measured  at  fair  value  are  classified  in  their  entirety  based  on  the  lowest  level  of  input  that  is 
significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement 
in its entirety requires judgment and considers factors specific to the asset or liability. 

73

 
 
 
 
 
 
 
Table of Contents

WEX INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

The carrying values of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, and other 
liabilities approximate their respective fair values due to the short-term nature of such instruments. The carrying values of certificates 
of deposit, interest-bearing money market deposits and borrowed federal funds approximate their respective fair values as the 
interest rates on these financial instruments are variable market-based rates. All other financial instruments are reflected at fair 
value on the consolidated balance sheets.

Revenue Recognition

The majority of the Company’s revenues are comprised of transaction-based fees, which are generally calculated based 
on  measures  such  as  (i) percentage  of  dollar  value  of  volume  processed;  (ii) number  of  transactions  processed;  or  (iii) some 
combination thereof. The Company has entered into agreements with major oil companies, fuel retailers, vehicle maintenance 
providers, online travel agencies and health partners which provide products and/or services to the Company’s customers. These 
agreements specify that a transaction is deemed to be captured when the Company has validated that the transaction has no errors 
and has accepted and posted the data to the Company’s records. The Company recognizes revenues when persuasive evidence of 
an arrangement exists, the products and services have been provided to the client, the sales price is fixed or determinable and 
collectability is reasonably assured. 

The Company generally records revenue net of costs based on the following criteria: (i) the Company is not the primary 
obligor in the arrangement; (ii) the Company has no inventory risk; (iii) the Company does not have reasonable latitude with 
respect to establishing the price for the product; (iv) the Company does not make any changes to the product or have any involvement 
in the product specifications; and, (v) the amount the Company earns for its services is fixed, within a limited range. 

The Company enters into contracts with certain large customers or strategic relationships that provide for fee rebates tied 
to performance milestones. Rebates are recorded as a reduction in revenue in the same period that revenue is earned or performance 
occurs. Rebates and incentives are calculated based on estimated performance and the terms of the related business agreements.

A description of the major components of revenue are as follows:

Payment Processing Revenue. Revenue consists of transaction fees as well as interchange income:

• 

• 

• 

Fleet transaction fees are assessed to major oil companies, fuel retailers and vehicle maintenance providers. We 
extend short-term credit to the fleet customer and pay the purchase price for the fleet customer’s transaction, 
less the payment processing fees we retain, to the merchant. We collect the total purchase price from the fleet 
customer. The fee charged is generally based upon a percentage of the total transaction amount; however, it may 
also be based on a fixed amount charged per transaction or on a combination of both measures. The Company 
records revenue at the time the transaction is captured.  

In Europe, our fleet payment processing revenue is specifically derived from the difference between the negotiated 
price of the fuel from the supplier and the agreed upon price paid by the fleets.  

Interchange income is earned from the Company’s suite of card products in the Fleet Solutions and Health and 
Employee Benefit Solutions segments, as well as on our virtual card technology. Interchange income is a fee 
paid by a merchant bank to the card-issuing bank through the interchange network. Interchange fees are set by 
the credit card providers. The Company recognizes interchange income as earned.

With regard to fleet and travel payment processing revenue, the Company is generally responsible for the collection of 
the total transaction amount from the customer and the payment to the merchant of their sales amount, net of the payment processing 
revenue earned by the Company, and as such, recognizes revenue net of the cost of the underlying products and services. As a 
consequence, the Company’s accounts receivable and accounts payable related to its payment processing revenues are reflective 
of the total transaction amount processed by the Company, not the Company’s revenue.

Account Servicing Revenue. In our Fleet Solutions segment, account servicing revenue is primarily comprised of monthly 
fees based on vehicles serviced. These fees are primarily in return for providing monthly vehicle data reports. In our Health and 
Employee Benefit Solutions segment, we also recognize account servicing fees for the per-participant per-month fee charged per 
consumer on our healthcare financial technology platform. Account servicing revenue is recognized monthly, as the Company 
fulfills its contractual service obligations. 

Finance Fees. The Company earns revenue by assessing monthly finance fees on accounts with overdue balances. These 
fees are recognized as revenue at the time the fees are assessed. The finance fee is calculated using a stated late fee rate based on 

74

 
 
 
 
 
 
 
 
 
Table of Contents

WEX INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

the entire balance outstanding from the customer or a minimum, whichever is higher. On occasion, these fees are waived to maintain 
customer goodwill. The Company’s established reserve for such waived amounts is estimated and offset against the late fee revenue 
recognized. These waived fees amounted to approximately $16,900, $10,900 and $6,000 in 2017, 2016 and 2015, respectively. 
The Company engages in factoring, the purchase of accounts receivable from a third party at a discount. Revenue earned in this 
transaction is recorded in finance fees. We also recognize fees for interest associated with the Company’s fuel desk product and 
revenue earned on the Company’s foreign salary advance product. 

Other. The Company earns transaction fees, which are principally based on the number of transactions processed; however, 

the fees may be a percentage of the total transaction amount. These fees are recognized at the time the transaction is captured.

The Company assesses fees for providing ancillary services, such as information products and services, professional 
services and marketing services. Other revenues also include international settlement fees, fees for overnight shipping, certain 
customized electronic reporting and customer contact services provided on behalf of certain of the Company’s customers. Service 
related revenues are recognized in the period that the work is performed.

Interest and dividends earned on investments in available-for-sale securities are included in other revenues. Such income 

is recognized in the period that it is earned.

The Company sells telematics devices as part of its WEX Telematics program. The Company recognizes revenue from 

these sales when the customer has accepted delivery of the product and collectability of the sales amount is reasonably assured.

From time to time the Company enters into agreements with suppliers, partners and customers and offers incentives to 
establish access to new channels, enter new market segments and expand the use and acceptance of WEX products and services. 
As part of these agreements the Company may agree to pay an up-front bonus or fee. The Company capitalizes these payments 
within other assets in the consolidated balance sheets and amortizes each monthly, generally on a straight-line basis against the 
related revenue earned throughout the life of the agreement.  

Stock-Based Compensation

The Company recognizes the fair value of all stock-based payments to employees in its financial statements. The Company 
estimates the fair value of service-based stock option awards and market performance-based stock option awards on the grant date 
using a Black-Scholes-Merton valuation model and a Monte Carlo simulation model, respectively. The fair value of Restricted 
Stock Units (“RSUs”), including Performance Based Restricted Stock Units (“PBRSUs”), is determined and fixed on the grant 
date based on the Company's stock price. 

Stock-based compensation expense is net of estimated forfeitures and is recorded over each award's requisite service 
period. The Company uses the straight-line methodology for recognizing the expense associated with service-based stock options 
and RSU grants and a graded-vesting methodology for the expense recognition of market performance-based stock options and 
PBRSUs. 

Stock-based compensation is recorded in salary and other personnel expense in the consolidated statements of income.

Advertising Costs

Advertising and marketing costs are expensed in the period incurred. During the years ended December 31, 2017, 2016 

and 2015, advertising expense was $17,141, $14,864 and $12,891, respectively.

Income Taxes

Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities 
are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of 
existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates 
expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The 
effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. 

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods 
in which the associated temporary differences became deductible. A valuation allowance is established for those jurisdictions in 
which deferred tax assets realization is deemed less than more likely than not.

Current accounting guidance prescribes a recognition threshold and measurement attribute for the financial statement 
recognition and measurement of a tax position taken or expected to be taken in a tax return. This accounting guidance also provides 
guidance  on  derecognition,  classification,  interest  and  penalties,  accounting  in  the  interim  periods,  disclosure,  and  transition. 
Penalties and interest related to uncertain tax positions are recognized as a component of income tax expense. To the extent penalties 
and interest are not assessed with respect to uncertain tax positions, amounts accrued are reduced and reflected as a reduction of 
the overall income tax provision.

Earnings per Share

Basic earnings per share is computed by dividing net earnings attributable to shareholders by the weighted average number 
of shares of common stock and vested deferred stock units (“DSUs”) outstanding during the year. The computation of diluted 
earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased for the assumed 
exercise of dilutive options and assumed issuance of unvested RSUs and DSUs and unvested PBRSUs for which the performance 
condition has been met as of the date of determination using the treasury stock method unless the effect is anti-dilutive. The treasury 
stock method assumes that proceeds, including cash received from the exercise of employee stock options and the total unrecognized 
compensation expense for unvested share-based compensation awards, would be used to purchase the Company's common stock 
at the average market price during the period. Prior to the January 2017 adoption of ASU 2016-09, the treasury stock method also 
included excess tax benefits in its proceeds calculation.

The  following  table  summarizes  net  earnings  attributable  to  shareholders  and  reconciles  basic  and  diluted  shares 

outstanding used in the earnings per share computations:

The financial statements of the Company’s foreign subsidiaries, where the local currency is the functional currency, are
translated to U.S. dollars using year-end spot exchange rates for assets and liabilities, average exchange rates for revenue and 
expenses and historical exchange rates for equity transactions. The resulting foreign currency translation adjustment is recorded 
as a component of accumulated other comprehensive loss.

Realized and unrealized gains and losses on foreign currency transactions as well as the re-measurement of the Company's 
cash, receivable and payable balances that are denominated in foreign currencies, are recorded directly in net foreign currency 
gain (loss) in the consolidated statements of income. However, gains or losses resulting from intercompany transactions where 
repayment  is  not  anticipated  for  the  foreseeable  future  are  not  recognized  in  the  consolidated  statements  of  income.  In  these 
situations, the gains or losses are deferred and included as a component of accumulated other comprehensive loss. In addition, 
gains and losses associated with the Company's foreign currency exchange derivatives are recorded in net foreign currency gain 
(loss) in the consolidated statements of income. 

Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss includes unrealized gains and losses on available-for-sale securities and foreign 
currency translation adjustments pertaining to the net investment in foreign operations. Amounts are recognized net of tax to the 
extent applicable. Realized gains or losses on securities transactions are classified as non-operating in the consolidated statements 
of income.

Recent Accounting Pronouncements

The following table provides a brief description of recent accounting pronouncements that could have a material effect 

on our financial statements:

Standard
Description
Adopted During the Year Ended December 31, 2017
Accounting Standards
Update (“ASU”)
2016-09 Compensation-
Stock Compensation
(Topic 718):
Improvements to
Employee Share-Based
Payment Accounting

This standard simplifies several
aspects of accounting for employee
share-based payment transactions,
including the accounting for
income taxes, forfeitures, statutory
tax withholding requirements, and
classification in the statement of
cash flows.

Date/Method of Adoption

January 1, 2017

Effect on financial statements or other significant
matters

Prior to the adoption of this guidance, the Company used 
the "with and without" method to determine when excess 
tax benefits were realized. As a result of certain US net 
operating loss carryforwards, excess tax benefits to date 
have not reduced taxes paid and therefore were not 
previously recognized in our financial statements. 

This standard required prospective recognition of all the 
tax effects related to share-based payments in the income 
statement. The impact of adoption was recorded as a 
cumulative effect adjustment to retained earnings of 
$261. For the year ended December 31, 2017, the 
Company recognized approximately $1,600 of excess tax 
benefits within our income tax provision. The Company 
has elected to prospectively classify these excess tax 
benefits as cash flows from operating activities effective 
January 1, 2017. The Company will continue to estimate 
the number of awards expected to vest, rather than 
electing to account for forfeitures as they occur. Adoption 
of this standard has not impacted the Company's 
minimum statutory tax withholding practices.

ASU 2017-09
Compensation—Stock
Compensation (Topic
718): Scope of
Modification
Accounting

This standard clarifies when a
change to the terms or conditions
of a share-based payment award
must be accounted for as a
modification. Under the new
guidance, an entity will not apply
modification accounting to a share-
based payment award if there is no
change to the award’s fair value,
vesting conditions and
classification as an equity or
liability instrument.

Not Yet Adopted as of December 31, 2017

ASU 2016-18
Statement of Cash
Flows (Topic 230):
Restricted Cash

ASU  2016-13
Financial Instruments-
Credit Losses (Topic
326): Measurement of
Credit Losses on
Financial Instruments

This standard clarifies the
classification and presentation of
restricted cash in the statement of
cash flows. The statement of cash
flows must explain the change
during the period in the total of
cash and cash equivalents and
amounts described as restricted
cash or cash equivalents.

This standard requires financial
assets measured at amortized cost
basis to be presented at the net
amount expected to be collected.
The measurement of expected
credit losses will be based on
historical experience, current
conditions, and reasonable and
supportable forecasts that impact
the collectability of the reported
amount.

The Company elected to early
adopt this standard effective
July 1, 2017.

The adoption has not impacted the Company's 
consolidated financial statements and related disclosures.

The standard is effective for
annual reporting periods
beginning after December 15,
2017, including interim
periods within those fiscal
years, and requires
retrospective application to all
periods presented. Early
adoption is permitted.

The standard is effective for
annual reporting periods
beginning after December 15,
2019, including interim
periods within those fiscal
years.

Upon adoption, restricted cash will be included in cash 
and restricted cash equivalents when reconciling the 
beginning of year and end of year amounts presented on 
the consolidated statements of cash flows. Restricted 
cash totaled $18,866 and $22,412 as of December 31, 
2017 and 2016, respectively, and is recorded in other 
assets on the consolidated balance sheets.

The Company is evaluating the impact the standard will 
have on the consolidated financial statements and related 
disclosures.

Standard

Description

ASU 2014-09 Revenue
from Contracts with
Customers (Topic 606)

This standard supersedes most 
existing revenue recognition 
guidance under GAAP. The new 
revenue recognition standard 
requires entities to recognize 
revenue for the transfer of 
promised goods or services to 
customers in an amount that 
reflects the consideration to which 
the entity expects to be entitled in 
exchange for those goods or 
services. In addition, the standard 
requires disclosure of the nature, 
amount, timing and uncertainty of 
revenue and cash flows arising 
from contracts with customers. 

Date/Method of Adoption

The Company adopted this 
standard on January 1, 2018. 
The guidance permits two 
methods of adoption: full 
retrospective approach, which 
requires an entity to restate 
each prior period that is 
reported in the financial 
statements and modified 
retrospective approach, which 
requires a cumulative 
adjustment to retained 
earnings as of the effective 
date, without restatement of 
prior period amounts. The 
Company adopted the 
standard using the modified 
retrospective method.

Effect on financial statements or other significant
matters

Topic 606 does not apply to rights or obligations 
associated with financial instruments (e.g. interest 
income), including the Company’s finance fee and 
interest income from banking relationships and 
cardholders. In addition, fees associated with cardholder 
arrangements are outside the scope of Topic 606. As a 
result of detailed analysis, management has determined 
that approximately 30 percent of consolidated revenues 
for the year ended December 31, 2017 are outside the 
scope of Topic 606.

The Company’s revenue from discount and interchange, 
transaction processing and certain fees is within the 
scope of Topic 606. FASB and its Transition Resource 
Group have issued clarifications on various aspects of 
ASU 2014-09. The Company has determined there will 
be two significant changes in the classification on our 
consolidated statement of income which will impact 
reported total revenues and operating expenses but have 
no impact on income from operations.

• 

• 

• 

Certain amounts paid to partners in our Fleet 
Solutions and Travel and Corporate Solutions 
segments have been determined to fall under 
the cost to obtain a contract guidance. As a 
result, these amounts, which were previously  
presented net of revenues, will be reflected as 
a selling expense going forward. Based on 
2017 results, this change  would have 
increased both reported revenues and 
expenses by approximately $52,000.

Network fees paid to Visa and MasterCard  by 
all three of our segments, which have 
previously been presented within service fees 
expense, will be presented net of revenue 
going forward. Based on 2017 results, this 
change would have reduced both reported 
revenues and expenses by approximately 
$24,000. The majority of network fee 
expenses are incurred by our Travel and 
Corporate Solutions segment. 

Under the new guidance certain costs to 
obtain a contract, such as sales commissions 
are to be capitalized and amortized over the 
life of the contract, with a practical expedient 
available for contracts under one year in 
duration. We have evaluated our worldwide 
sales commission structure and determined 
that the vast majority of commission expense 
will continue to be expensed. In 2017, we 
incurred approximately $1,000 of sales 
commissions which meet the criteria for 
capitalization under the new guidance.

Except for the items mentioned above, we have 
determined that the timing and measurement of revenue 
associated with the Company’s transaction processing 
services, including discount and interchange and other 
transaction processing fees, will not be significantly 
impacted by the new standard. As such, we estimate that 
applying the modified retrospective method to 
outstanding contracts as of our January 1, 2018 
implementation date will have an immaterial cumulative 
effect on the opening balance of 2018 retained earnings. 

The Company has implemented changes to its accounting 
policies, business processes and internal controls to 
support the recognition, measurement and disclosure 
requirements under the new standard.

Business Acquisitions and Other Intangible Asset Acquisitions

The Company incurred and expensed costs directly related to completed acquisitions of $956, $19,168 and $342 in 2017, 

2016 and 2015, respectively, which are included primarily within service fees in the consolidated statements of income.

AOC

Effective October 18, 2017, the Company acquired certain assets and assumed certain liabilities of AOC Solutions and 
one of its affiliate companies, 3Delta Systems, Inc. (collectively “AOC”), an industry leader in commercial payments technology. 
The acquisition of AOC, a longstanding technology provider for our virtual card product, will broaden the Company's capabilities, 
increase our pool of employees with payments platform expertise and allow the Company to evolve with the needs of its customers 
and partners through the use of AOC’s payments processing technology platforms. 

The Company purchased AOC for $129,828, which was funded with cash on hand and through borrowings under the 
2016  Credit  Agreement.  The  Company  records  adjustments  to  the  assets  acquired  and  liabilities  assumed  throughout  the 
measurement period, which may be up to one year from the acquisition date. The Company has obtained information to assist in 
determining  the  fair  values  of  certain  assets  acquired  and  liabilities  assumed  since  the  acquisition,  resulting  primarily  in  the 
recording of other intangible assets and goodwill. Goodwill is calculated as the consideration in excess of net assets recognized 
and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately 
recognized, including synergies derived from the acquisition. The goodwill and intangible assets recorded from this business 
combination were assigned to our Travel and Corporate Solutions segment.

The Company has not finalized the purchase accounting and is currently evaluating the tax basis and the allocation of 
book basis to the assets acquired and liabilities assumed in this business combination. Specifically, the Company is still reviewing 
the valuation as well as performing procedures to verify the completeness and accuracy of the data used in the independent valuation 
for intangible assets identified in the table below. Additionally, we are assessing the value of acquired in-process research and 
development software. The preliminary estimates could change significantly upon completion of this evaluation. The goodwill 
recognized in this business combination will be deductible for income tax purposes.

The following is a summary of the preliminary allocation of the purchase price to the assets and liabilities acquired:

Since the acquisition date, the operations of AOC contributed net revenues of approximately $6,685 and net loss before 
taxes of approximately $620 during 2017. No pro forma information has been included in these financial statements as the operations 
of AOC for the period that they were not part of the Company are not material to the Company's revenues, net income and earnings

EFS

WEX INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

On July 1, 2016,  the Company acquired all of the outstanding membership interests of EFS, a provider of customized 
payment solutions for fleet and corporate customers with a focus on the large and mid-sized over-the-road fleets. The acquisition 
enabled the Company to expand its customer footprint and to utilize EFS' technology to better serve the needs of all fleet customers.

In consideration for the acquisition of EFS, the Company issued 4,012 shares of its common stock valued at approximately 
$355,000 based on the July 1, 2016 closing price of the Company's common stock on the NYSE. This represented approximately 
9.4 percent of the Company's outstanding common stock after giving effect to the issuance of the new shares in connection with 
this acquisition. The cash consideration for the transaction totaled approximately $1,182,000, and was funded with amounts received 
under the 2016 Credit Agreement described further in Note 13, Financing Debt. The value of the total cash and stock consideration 
paid for the acquisition of EFS was approximately $1,444,000, net of approximately $93,000 in cash acquired. 

The  Company  obtained  information  to  determine  the  fair  values  of  certain  assets  acquired  and  liabilities  assumed 
throughout the one year measurement period and recorded adjustments to the assets acquired and liabilities assumed, resulting in 
the recording of other intangible assets and goodwill as described below. Goodwill is calculated as the consideration in excess of 
net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually 
identified and separately recognized, including synergies derived from the acquisition. The Company finalized the EFS purchase 
accounting in the second quarter of 2017.

The tax structure of EFS consists of limited liability companies and corporations. The Company’s  tax election will allow 
a step-up in tax basis related to its 49.5 percent direct ownership in the parent limited liability company. The remaining 50.5 percent
ownership in the parent limited liability company is held by another limited liability company, taxed as a corporation, that is part 
of the EFS structure and will therefore receive carry over tax basis. The difference between book and tax basis resulting from 
receiving carry over tax basis has been reflected in the financial statements as an investment in partnership deferred tax liability. 
The  Company  has  determined  that  approximately  $557,000  of  the  goodwill  recognized  in  this  business  combination  will  be 
deductible for income tax purposes.

The  pro  forma  financial  information  presented  below  includes  the  effects  of  the  EFS  acquisition  as  if  it  had  been 
consummated on January 1, 2015. These pro forma results have been calculated after applying the Company's accounting policies 
and adjusting results to reflect the intangible amortization and interest expense associated with the 2016 Credit Agreement used 
to fund the acquisition and related income tax results assuming they were applied and incurred since January 1, 2015. In addition, 
non-recurring costs that were incurred in 2016 and are directly attributable to the acquisition have been reflected in pro forma 
results for the year ended December 31, 2015. Such adjustments include $19,168 of transaction costs and $7,074 of expenses

incurred as part of the July 2016 debt modification and extinguishment, net of the related income tax results. The pro forma results 
of operations do not include any cost savings or other synergies that may result from the acquisition or any estimated integration 
costs that have been or will be incurred by the Company. Accordingly, the following pro forma information is not necessarily 
indicative of either the future results of operations or results that would have been achieved if the acquisition had taken place at 
the beginning of 2015. Subsequent to the July 1, 2016 acquisition date, the operations of EFS contributed revenues of approximately 
$83,300 and net income before taxes of approximately $5,800 to the Company's 2016 consolidated statement of income.

On November 18, 2015, the Company purchased the stock of Benaissance for $80,677. The transaction was financed 
through the Company’s cash on hand and existing credit facility. Benaissance provides financial management for health benefits 
administration  by  offering  SaaS  solutions  for  individual  single  point  and  consolidated  group  premium  billing. The  Company 
acquired Benaissance to enhance the Company's positioning in the growing healthcare market. 

The  Company  obtained  information  to  determine  the  fair  values  of  certain  assets  acquired  and  liabilities  assumed 
throughout the one year measurement period and recorded adjustments to the assets acquired and liabilities assumed, resulting in 
the recording of other intangible assets and goodwill as described below. Goodwill is expected to be deductible for tax purposes.

Since the acquisition date, the operations of Benaissance contributed net revenues of approximately $2,085 and net income 
of approximately $399 during 2015. The results of operations for Benaissance are presented in the Company's Health and Employee 
Benefit Solutions segment.

Divestitures

Telapoint

During the year ended December 31, 2017, the Company sold $8,942 in net assets of its Telapoint business for proceeds 
of $29,900, subject to a working capital adjustment. The sale resulted in a pre-tax book gain of $20,958. Costs incurred related to 
this divestiture were immaterial. Prior to the sale, the Telapoint business was assigned to our North American Fleet reporting unit, 
which is included within our Fleet Solutions reportable segment. 

The divestiture was not material to the Company's annual revenue, net income or earnings per share. The Company does 

not view this divestiture as a strategic shift in its operations. 

rapid! PayCard 

On January 7, 2015, the Company sold the assets of its rapid! PayCard operations for $20,000, which resulted in a pre-
tax book gain of approximately $1,215. The Company's primary focus in the U.S. continues to be in the fleet, travel, and healthcare 
industries. As such, the Company divested the operations of rapid! PayCard, which were not material to the Company's annual 
revenue, net income or earnings per share. The Company does not view this divestiture as a strategic shift in its operations.

5.

Accounts Receivable

In general, the Company’s trade receivables provide for payment terms of 30 days or less. Receivables not paid within 

the terms of the customer agreement are generally subject to late fees based upon the outstanding customer receivable balance.

The Company extends revolving credit to certain small fleet customers. These accounts are also subject to late fees and 
balances that are not paid in full are subject to interest charges based on the revolving balance. The Company had approximately 
$12,200 and $3,400 in receivables with revolving credit balances as of December 31, 2017 and 2016, respectively.

Concentration of Credit Risk

The receivables portfolio consists of a large group of homogeneous smaller balances from customers across a wide range 
of industries, which are collectively evaluated for impairment. No one customer represented 10 percent or more of the outstanding 
receivables balance as of December 31, 2017. One customer represented 11 percent of the outstanding receivables balance as of 
December 31, 2016. The following table presents the outstanding balance of accounts receivable that are less than 60 days past 
due, in each case as a percentage of total trade accounts receivable:

2016

95%

97%

93%

98%

Receivables are generally written off when they are 150 days past due or upon declaration of bankruptcy by the customer. 
The reserve for credit losses is calculated by an analytic model that also takes into account other factors, such as the actual charge-
offs for the preceding reporting periods, expected charge-offs and recoveries for the subsequent reporting periods, a review of past 
due accounts receivable balances, changes in customer payment patterns, known fraudulent activity in the portfolio, as well as 
leading economic and market indicators.

1 During 2017, the majority of the increase relates to higher incidences of magnetic stripe card skimming fraud.

2 The Company earns revenue by assessing monthly finance fees on accounts with overdue balances. These fees are recognized as revenue at the time the fees are 
assessed. The finance fee is calculated using the greater of a minimum charge or a stated late fee rate multiplied by the outstanding balance that is subject to a late 
fee charge. On occasion, these fees are waived to maintain customer goodwill. Charges to other accounts represents the offset against the late fee revenue recognized 
when the Company establishes a reserve for such waived amounts.

balance sheets. See Note 16, Employee Benefit Plans for additional information.

The Company reviews its investments to identify and evaluate indications of possible impairment. Factors considered in 
determining whether a loss is temporary include the length of time and extent to which the fair value has been less than the cost 
basis, the financial condition and near-term prospects of the investee, and the Company’s intent and ability to hold the investment 
for a period of time sufficient to allow for any anticipated recovery in market value. Substantially all of the Company’s fixed 
income securities are rated investment grade or better. The amount of available-for-sale securities that have been in a continuous 
unrealized loss position for more than twelve months is insignificant. The Company’s management has determined that these gross 
unrealized losses at December 31, 2017 and 2016 are temporary in nature.

The Company had maturities of available-for-sale securities of $631, $495 and $594 for the years ended December 31

respectively. There were no borrowings against these lines of credit at December 31, 2017 and 2016.

Other Debt

WEX Latin America Debt

WEX Latin America had debt of approximately $9,747 and $30,755 as of December 31, 2017 and 2016, respectively. 

This is comprised of credit facilities and loan arrangements with various maturity dates. 

Participation Debt

WEX Bank maintains agreements with third-party banks to fund customer balances that exceed WEX Bank's lending 
limit to an individual customer. During the year ended December 31, 2017, the Company increased the funding capacity of these 
arrangements by $90,000 to $185,000. Associated borrowings carry a variable interest rate of 1 month to 3 month LIBOR plus a 
margin of 225 basis points. The balance of the debt was approximately $185,000 and $95,000 at December 31, 2017 and December 
31, 2016 respectively, and was secured by an interest in the underlying customer receivables. The balance will fluctuate on a daily 
basis based on customer funding needs. The commitment will mature in amounts of approximately $85,000 and $50,000 on May 30, 
2018 and December 31, 2021, respectively, with the remaining $50,000 maturing on demand.

and 2017, we entered into five interest rate swap contracts. Collectively, these derivative contracts are intended to fix the future 
interest payments associated with $1.3 billion of our variable rate borrowings at between 0.896% to 2.212%.

Foreign Currency Exchange Program

The Company utilizes a limited foreign currency exchange hedging program, entering into short-term foreign currency 
swaps to convert the foreign currency exposures of certain foreign currency denominated intercompany loans and investments to 
the base currency. The Company will continue to monitor its foreign currency exposure for discrete items and may, from time to 
time, hedge certain foreign currency transactions.

Fuel Derivatives Program

The Company previously utilized fuel price derivative instruments, which were designed to reduce the volatility of the 
Company’s cash flows associated with its fuel price-related earnings exposure in North America. After the first quarter of 2016, 
the Company was no longer hedged for changes in fuel prices. Management will continue to monitor the fuel price market and 
evaluate its alternatives as it relates to this hedging program.

During the first quarter of 2017, WEX Europe Services entered into a factoring arrangement with an unrelated third-party 
financial institution (the “Purchasing Bank”) to sell certain of its accounts receivable in order to accelerate the collection of the 
Company's cash and reduce internal costs, thereby improving liquidity. Under this arrangement, the Purchasing Bank establishes 
a credit limit for each customer account. The factored receivables are without recourse to the extent that the customer balances 
are maintained at or below the established credit limit. For customer receivable balances in excess of the Purchasing Bank's credit 
limit, the Company maintains the risk of default. The Company obtained a true sale opinion from an independent attorney, which 
states that the factoring agreement creates a sale of receivables under local law for amounts transferred both below and above the 
established credit limits. Additionally, there are no indications of the Company's continuing involvement in the factored receivables. 
As a result, the Purchasing Bank is deemed the purchaser of these receivables and is entitled to enforce payment of these amounts 
from the debtor. 

This factoring arrangement is accounted for as a sale and accordingly the Company records the receivables sold as a 
reduction of accounts receivable and proceeds as cash provided by operating activities. The Company sold approximately $574,400
of receivables under this arrangement during year ended December 31, 2017. Proceeds received are recorded net of applicable 
expenses, interest and commissions. This resulted in a loss on factoring of approximately $3,700 for the year ended December 31, 
2017, which was recorded in Other expenses in the consolidated statement of income. As of December 31, 2017, the Company 
had associated factoring receivables of approximately $61,800, of which approximately $3,700 were in excess of the established 
credit limit. Charge-backs on balances in excess of the credit limit during the year ended December 31, 2017 were insignificant.

WEX Latin America Accounts Receivable Factoring

During  the  first  quarter  of  2017,  WEX  Latin America  entered  into  a  factoring  agreement  to  sell  certain  unsecured 
receivables associated with our salary payment card product, without recourse, to an unrelated third-party financial institution. 
Under the terms of the agreement, the Company retains no rights or interest and has no obligations with respect to the receivables. 
As such, the factoring under this arrangement is accounted for as a sale. The Company sold $16,300 of receivables during the year 
ended December 31, 2017. This resulted in a loss on factoring of $800 for the year ended December 31, 2017, which was recorded 
in Other expenses in the consolidated statement of income. The receivables sold under this agreement were recorded as a reduction

of accounts receivable and proceeds as cash provided by operating activities. There were no sales under this factoring arrangement 
during  the  second  half  of  2017;  a  securitization  agreement  replaced  this  factoring  arrangement  as  Brazil's  primary  funding 
mechanism. See Note 13, Financing Debt, for more information on this securitization arrangement.

2016 Credit Agreement 

On July 1, 2016, the Company entered into the 2016 Credit Agreement, which replaced the 2014 Credit Agreement. The 
2016 Credit Agreement provided for term loan facilities and a secured revolving credit facility, with a sublimit for letters of credit 
and swingline loans. Effective October 30, 2017, the Company entered into a Second Amendment to the 2016 Credit Agreement, 
which added $100,000 of capacity to its revolving line of credit to provide additional liquidity and flexibility. As amended, the 
2016 Credit Agreement provides for a tranche A term loan facility in an amount equal to $455,000, a tranche B term loan facility 
in an amount equal to $1,200,000 and a $570,000 secured revolving credit facility. Under this agreement, $1,025,000 matures on 
July 1, 2021 and $1,200,000 matures on July 1, 2023. Prior to maturity, amounts under the credit facility will be reduced by 
mandatory payments. Additional loans may be made available under the 2016 Credit Agreement upon request of the Company 
subject to specified terms and conditions, including receipt of lender commitments. Proceeds from the 2016 Credit Agreement 
may  be  used  for  working  capital  purposes,  acquisitions,  payment  of  dividends  and  other  restricted  payments,  refinancing  of 
indebtedness and other general corporate purposes.

As of December 31, 2017, the Company had $570,000 borrowing capacity, subject to the covenants as described below. 
As of December 31, 2017 and 2016, the Company has posted approximately $27,500 and $13,300, respectively, in letters of credit 
as collateral for lease agreements and virtual card and fuel payment processing activity at its foreign subsidiaries. The Company 
had approximately $406,000 available under the revolving credit facility as of December 31, 2017. As of both December 31, 2017 
and 2016, amounts outstanding under the 2016 Credit Agreement bore a weighted average effective interest rate of 4.2%. 

Effective July 3, 2017, the Company repriced the secured term loans under the 2016 Credit Agreement (the “2016 First 
Amendment”), which reduced the applicable interest rate margin at current borrowing levels for both LIBOR borrowings and base 
rate borrowings for the Company's tranche A term loans and tranche B term loans. The consolidated leverage ratio as defined in 
the 2016 Credit Agreement (i.e. consolidated funded indebtedness less up to $350,000 in permitted securitization transactions of 
the Company and its subsidiaries to consolidated EBITDA) was also modified for purposes of calculating the interest rate margin 
for tranche A term loans and revolving loans and determining compliance with the financial covenant by allowing the Company 
to exclude up to $75 million of certain corporate cash balances for purposes of determining consolidated funded indebtedness.

After giving effect to the terms of the 2016 First Amendment, amounts outstanding under the 2016 Credit Agreement 
were repriced to bear interest at a rate equal to, at the Company’s option, (a) the Eurocurrency Rate, as defined in the 2016 Credit 
Agreement, plus a margin of between 1.75% to 3.25% (2.75% at December 31, 2017) with respect to the revolving credit facility, 
between 1.75% to 2.75% (2.25% at December 31, 2017) with respect to the tranche A term loan facility, which represents a reduction 
of 50 basis points and 2.75% with respect to the tranche B term loan facility, which represents a reduction of 75 basis points (with 
the Eurocurrency Rate subject to a 0.00% floor), in each case, based on the consolidated leverage ratio or (b) the highest of (i) the 
Federal Funds Rate plus 0.50%, (ii) the prime rate announced by Bank of America, and (iii) the Eurocurrency Rate plus 1.00%, 

91

 
 
 
 
 
Table of Contents

WEX INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

in each case plus a margin of 0.75% to 2.25% (1.75% at December 31, 2017) with respect to the revolving credit facility, 0.75%
to 1.75% (1.25% at December 31, 2017) with respect to the tranche A term loan facility and 2.25% with respect to the tranche B 
term loan facility, with the margin determined in the case of the revolving credit facility and the tranche A term loan facility based 
on the consolidated leverage ratio. The Company maintains interest rate swap agreements to manage the interest rate risk associated 
with its outstanding variable-interest rate borrowings under the 2016 Credit Agreement. See Note 11, Derivative Instruments, for 
further discussion. 

In addition, the Company has agreed to pay a quarterly commitment fee at a rate per annum ranging from 0.30% to 0.50% 
(0.45% at December 31, 2017) based on the consolidated leverage ratio of the daily unused portion of the 2016 Credit Agreement. 
The tranche B term loan facility was issued with an original issue discount of 1.00%. 

As the debt repricings under the 2016 First Amendment were not considered substantially different, the Company applied 
modification accounting and no gain or loss was recognized as a result of the debt modification. Amounts paid as part of this 
repricing were not material.

The 2016 Credit Agreement requires the Company to prepay outstanding term loans, subject to certain exceptions:

• 

solely with respect to the tranche B term loan facility, currently with 50% (subject to reduction to 25% and 0%
based upon the Company’s consolidated leverage ratio) of the Company’s annual Excess Cash Flow (as defined 
in the 2016 Credit Agreement);

•  with 100% of the net cash proceeds of certain asset sales where the proceeds exceed certain thresholds, and 
certain casualty and condemnation events, subject to reinvestment rights and certain other exceptions; and

•  with 100% of the net cash proceeds of any incurrence or issuance of certain debt, other than debt permitted under 

the 2016 Credit Agreement.

The Company may voluntarily prepay outstanding loans from time to time, subject to certain conditions, without premium 
or penalty other than customary “breakage” costs with respect to Eurocurrency Rate loans, provided, however, that if on or prior 
to the date that is six (6) months following the 2016 First Amendment effective date, the Company prepays any loans under the 
tranche B term loan facility in connection with a repricing transaction, the Company must pay a prepayment premium of 1.00%
of the aggregate principal amount of the tranche B term loans so prepaid.

The Company is required to make scheduled quarterly payments each equal to 1.25% in the case of the tranche A term 
loan facility, and 0.25% in the case of the tranche B term loan facility, of the original principal amount of the respective term loans 
made on the closing date, with the balance due at maturity. 

The  2016  Credit Agreement  contains  customary  representations  and  warranties,  as  well  as  affirmative  and  negative 
covenants. The 2016 Credit Agreement also requires, solely for the benefit of the lenders under the tranche A term loan facility 
and the revolving credit facility, that the Company maintain at the end of each fiscal quarter the following financial ratios:

• 

• 

a consolidated EBITDA to consolidated interest charge coverage ratio of no less than 3.25 to 1.00; and

a consolidated funded indebtedness (excluding (i) up to an agreed amount of consolidated funded indebtedness 
under  permitted  securitization  transactions  and  (ii)  the  non-recourse  portion  of  any  permitted  factoring 
transaction) to consolidated EBITDA ratio of, initially, no more than 5.40 to 1.00, which ratio shall step down 
to 5.25 to 1.00 at December 31, 2016, 5.00 to 1.00 at December 31, 2017, 4.25 to 1.00 at December 31, 2018
and 4.00 to 1.00 at December 31, 2019.

The obligations under the 2016 Credit Agreement are secured by a security interest in, subject to certain exceptions, 
substantially all of the assets of the Company pursuant to the terms of a U.S. Security Agreement, dated as of July 1, 2016, in favor 
of Bank of America, as collateral agent for the lenders.

Debt Covenants

The 2016 Credit Agreement and the Indenture contain covenants that limit the Company and its subsidiaries’ ability and 
the  ability  of  its  restricted  subsidiaries  and,  in  certain  limited  circumstances, WEX  Bank  and  the  Company’s  other  regulated 
subsidiaries, to (i) incur additional debt, (ii) pay dividends or make other distributions on, redeem or repurchase capital stock, or 
make investments or other restricted payments, (iii) enter into transactions with affiliates, (iv) dispose of assets or issue stock of 
restricted subsidiaries or regulated subsidiaries, (v) create liens on assets, or (vi) effect a consolidation or merger or sell all, or 

92

 
 
 
 
 
 
 
Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

substantially all, of the Company’s assets. These covenants are subject to important exceptions and qualifications. At any time that 
the Notes are rated investment grade, which is not currently the case, and subject to certain conditions, certain covenants will be 
suspended with respect to the Notes. WEX Bank and the Company’s other regulated subsidiaries will not be subject to some of 
the restrictive covenants in the Indenture that place limitations on the Company and its restricted subsidiaries’ actions, and where 
WEX Bank and the Company’s regulated subsidiaries are subject to covenants, there are significant exceptions and limitations on 
the application of those covenants to WEX Bank and the Company’s regulated subsidiaries.

2014 Credit Agreement

On July 1, 2016, concurrently with the financing transactions discussed above, the Company repaid in full all outstanding 
amounts under the 2014 Credit Agreement and terminated all commitments by the lenders to extend further credit thereunder and 
all guarantees and security interests granted by the Company to the lenders thereunder. The Company did not incur any early 
termination penalties in connection with the termination of the 2014 Credit Agreement.

As of June 30, 2016, the Company had borrowings, net of loan origination fees, of $282,639 and $445,000 against its 
revolving credit facility and amortizing term loan arrangement, respectively. As of June 30, 2016, amounts outstanding under the 
amortizing term loan bore interest at a rate of LIBOR plus 200 basis points. The revolving credit facility bore interest at a rate 
equal to, at the Company's option, (a) LIBOR plus 200 basis points, (b) the prime rate plus 100 basis points for domestic borrowings; 
and the Eurocurrency rate plus 200 basis points for international borrowings. 

Notes Outstanding 

On January 30, 2013, the Company completed a $400,000 offering in an aggregate principal amount of 4.750 percent
senior notes due 2023 (the “Notes”) at an issue price of 100.0 percent of the principal amount, plus accrued interest, from January 30, 
2013, in a private placement to “qualified institutional buyers” as defined in Rule 144A under the Securities Act of 1933, as 
amended (the “Securities Act”), and in offshore transactions pursuant to Regulation S under the Securities Act. The Notes were 
issued pursuant to the Indenture among the Company, the guarantors listed therein, and The Bank of New York Mellon Trust 
Company, N.A., as trustee.

The Notes will mature on February 1, 2023, and interest will accrue at the rate of 4.750 percent per annum. Interest is 

only payable semiannually in arrears on February 1 and August 1 of each year, commencing on August 1, 2013. 

The Notes are guaranteed on a senior secured basis by each of the Company’s restricted subsidiaries and each of the 
Company’s regulated subsidiaries that guarantees the Company’s 2013 Credit Agreement, which, as of the issue date, consist of 
four of the Company’s restricted subsidiaries. WEX Bank, which represents a substantial amount of the Company’s operations, is 
not a guarantor and is not subject to many of the restrictive covenants in the indenture governing the Notes.

The Notes and guarantees described above are general senior secured obligations ranking equally with the Company’s 
existing and future senior debt, senior in right of payment to all of the Company’s subordinated debt, and effectively equal in lien 
priority to the Company’s 2016 Credit Agreement. In addition, the Notes and the guarantees are structurally subordinated to all 
liabilities of the Company’s subsidiaries that are not guarantors, including WEX Bank.

At any time on or after February 1, 2018, the Company may redeem the Notes, in whole or in part, at the following 
redemption prices (expressed as a percentage of principal amount of the Notes) if redeemed during the twelve month period 
beginning on February 1 of the following years: (i) 102.375 percent in 2018, (ii) 101.583 percent in 2019, (iii) 100.792 percent in 
2020, and (iv) 100.0 percent in 2021 and thereafter; plus, in each case, accrued and unpaid interest, if any, to, but excluding, the 
date of redemption. At any time prior to February 1, 2018, the Company could have redeemed the Notes, in whole or in part, at a 
redemption  price  equal  to  100.0  percent  of  the  principal  amount  of  such  Notes  redeemed  plus  a  “make-whole”  premium  (as 
described in the Indenture), together with any accrued and unpaid interest, if any, to, but excluding, the date of redemption.

Upon the occurrence of a change of control of the Company (as described in the Indenture), the Company must offer to 
repurchase the Notes at 101 percent of the principal amount of the Notes, plus accrued and unpaid interest, if any, to, but excluding, 
the date of repurchase.

WEX Latin America Securitization Facility

During the second quarter of 2017, WEX Latin America entered into a securitized debt agreement to sell certain unsecured 
receivables associated with our salary payment card product to an investment fund managed by an unrelated third-party financial 
institution. Under the terms of the agreement, the investment fund's purchase price incorporates a discount relative to the face 
value of the transferred receivables. Additionally, the investment fund compensates WEX Latin America for continuing to service 
these receivables through their duration, which on average is less than six months.

This securitization arrangement does not meet the derecognition conditions and accordingly WEX Latin America continues 
to report the transferred receivables in our consolidated balance sheet with no change in the basis of accounting. Additionally, we 
recognize the cash proceeds received from the investment fund and record offsetting securitized debt in our consolidated balance 
sheet.

During 2017, WEX Latin America securitized approximately $49,100 of receivables to the investment fund for cash 
proceeds  of  approximately  $43,800. This  $5,300  discount  is  recognized  as  operating  interest  in  the  Company's  consolidated 
statements of income using the effective interest method over the weighted average term of the salary advances. The Company 
received approximately $3,000 of servicing fee income upon the sale of these receivables, which is recognized as other revenue 
in our consolidated statements of income on a straight-line basis over the anticipated loan servicing period. As of December 31, 
2017, approximately $19,000 of securitized debt is recognized on our consolidated balance sheet related to this securitization 
arrangement.

Australian Securitization Facility 

During the second quarter of 2017, the Company extended an existing securitized debt agreement with the Bank of Tokyo-
Mitsubishi UFJ, Ltd. through April 2018. Under the terms of the agreement, each month, on a revolving basis, the Company sells 
certain of its Australian receivables to the Company's Australian Securitization Subsidiary. The Australian Securitization Subsidiary, 
in turn, uses the receivables as collateral to issue asset-backed commercial paper (“securitized debt”) for approximately 85 percent
of the securitized receivables. The amount collected on the securitized receivables is restricted to pay the securitized debt and is 
not available for general corporate purposes. 

The Company pays a variable interest rate on the outstanding balance of the securitized debt, based on the Australian 
Bank Bill Rate plus an applicable margin. The interest rate was 2.53 percent and 2.65 percent as of December 31, 2017 and 2016, 
respectively. The Company had securitized debt under this facility of approximately $90,000 and $78,600 as of December 31, 
2017 and 2016, respectively.

European Securitization Facility

On April 7, 2016, the Company entered into a five year securitized debt agreement with the Bank of Tokyo-Mitsubishi 
UFJ, Ltd. Under the terms of the agreement, the Company sells certain of its receivables from selected European countries to its 
European Securitization Subsidiary. The European Securitization Subsidiary, in turn, uses the receivables as collateral to issue 
securitized debt. The amount collected on the securitized receivables is restricted to pay the securitized debt and is not available 
for general corporate purposes. The amounts of receivables to be securitized under this agreement are determined by management 
on a monthly basis. The interest rate was 1.11 percent and 0.95 percent as of December 31, 2017 and 2016, respectively. The 
Company  had  securitized  debt  under  this  facility  of  approximately  $17,900  and  $5,700  as  of  December 31,  2017  and  2016, 
respectively.

Debt Issuance Cost

In the third quarter of 2016, the Company capitalized approximately $49,810 of debt issuance costs, including an original 
issue discount of $12,000 associated with the 2016 Credit Agreement. These debt issuance costs are being amortized into interest 
expense over the 2016 Credit Agreement's term using the effective interest method for the tranche A and B term loans and the 
revolver. Additionally, the Company expensed approximately $5,056 during the third quarter of 2016 related to noncapitalizable 
third-party costs incurred in connection with the modification of the certain 2014 Credit Agreement syndicate loans. 

The Company recognized a loss of $2,018 associated with the early extinguishment of the 2014 Credit Agreement during 
the year ended December 31, 2016, including a partial write-off of previously capitalized debt issuance costs and newly paid lender 
fees associated with the extinguishment of syndicate borrowings.

In January 2016, the Company began to incur ticking fees for the debt financing commitment associated with the 2016 
Credit Agreement in anticipation of the then pending acquisition of EFS. Pursuant to the terms set forth in the bank commitment 
letter, the ticking fees were calculated based on the financing commitment in the aggregate amount of $2,125,000, and remained 
in place until the closing of the EFS acquisition on July 1, 2016 (see Note 3, Business Acquisitions and Other Intangible Asset 
Acquisitions). Total ticking fees expensed to financing interest were $30,045 for the year ended December 31, 2016. In conjunction 
with the continued negotiation of the Company's new credit agreement, the amount of ticking fees to be paid at the time of closing 
was reduced by $7,874 to $22,171. The excess ticking fees were reflected as a reduction of the $49,810 debt issuance costs related 
to the 2016 Credit Agreement noted above and will be amortized over the 2016 Credit Agreement's term using the effective interest 
method for the tranche A and B term loans and the revolver.

Other 

As of December 31, 2017, WEX Bank pledged approximately $343,800 of fleet receivables held by WEX Bank to the 
Federal Reserve Bank as collateral for potential borrowings, through the Federal Reserve Bank Discount Window. Amounts that 
can be borrowed are based on the amount of collateral pledged to the Federal Reserve Bank and were $277,326 as of December 31, 
2017. WEX Bank had no borrowings on this line of credit through the Federal Reserve Bank Discount Window as of December 31, 
2017.

2017 Tax Act

WEX INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

On December 22, 2017, the 2017 Tax Act was signed into law making significant changes to the Internal Revenue Code. 
Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after 
December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system and a one-
time transition tax on the mandatory deemed repatriation of foreign earnings. The Company has estimated the provision for income 
taxes in accordance with the 2017 Tax Act and guidance available as of the date of this filing and as a result has recorded a 
provisional amount of one-time income tax benefit of $60,636 in the fourth quarter of 2017, the period in which the legislation 
was enacted.

The one-time income tax benefit includes: 

• 

• 

• 

a tax benefit of $62,488 related to the remeasurement of certain deferred tax assets and liabilities based on the tax rates 
at which they are expected to reverse in the future;

as discussed in Note 15, Tax Receivable Agreement, for the year ended December 31, 2017, the amount due under our 
tax receivable agreement decreased primarily as a result of the decline in the federal corporate income tax rate, resulting 
in the Company recognizing non-taxable income of $15,259. The favorable tax effect of this permanent difference was 
$5,726;

an income tax expense of $9,098 related to the one-time transition tax on the mandatory deemed repatriation of foreign 
earnings; and

• 

the reversal of net deferred tax liabilities of $1,520 related to the cumulative undistributed earnings.

The 2017 Tax Act also changes the taxation of foreign earnings, and companies generally will not be subject to United     

States federal income taxes upon the receipt of dividends from foreign subsidiaries and will not be permitted foreign tax credits 
related to such dividends. However, the 2017 Tax Act creates a new requirement to tax certain foreign earnings relating to GILTI. 
Based on the recent FASB guidance, the Company can elect an accounting policy choice of either treating taxes due on future U.S. 
inclusions  in  taxable  income  related  to  GILTI  as  a  current  period  expense  when  incurred  or  factoring  such  amounts  into  the 
Company’s measurement of its deferred taxes. Because of the complexity of the new GILTI tax rules, and anticipated guidance 
from the U.S. Treasury, we will continue to evaluate this provision of the 2017 Tax Act.  Therefore, we have not recorded any 
deferred taxes related to GILTI and have not elected an accounting policy for GILTI at this time.

Undistributed earnings of certain foreign subsidiaries of the Company amounted to $58,675 and $25,824 at December 31, 
2017 and 2016, respectively. These earnings are considered to be indefinitely reinvested. Beginning in 2018, except for GILTI, 
the Company will no longer record United States federal income tax on its share of the income of its foreign subsidiaries, nor will 
it record a benefit for foreign tax credits related to that income. Accordingly, the Company reversed net deferred tax liabilities 
related  to  its  cumulative  undistributed  foreign  earnings  and  deferred  tax  assets  for  related  foreign  tax  credits,  resulting  in  a 
corresponding net tax benefit in 2017. Upon distribution of these earnings in the form of dividends or otherwise, the Company 
would be subject to withholding taxes payable, where applicable, to foreign countries, but would have no further federal income 
tax liability.

On December 22, 2017, Staff Accounting Bulletin No. 118 was issued to address the application of U.S. GAAP in situations 
when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable 
detail to complete the accounting for certain income tax effects of the 2017 Tax Act. Accordingly, any subsequent adjustments to 
the amount of one-time benefit of $60,636 will be recorded to current income tax provision during the measurement period which 
is not expected to extend beyond one year from the enactment date. The effects of other provisions of the 2017 Tax Act are not 
expected to have a material impact on our consolidated financial statements.

40.7%

Our effective tax rate was 10.9 percent for 2017 as compared to 34.0 percent for 2016. The decline in our tax rate is 
primarily due the reduction of our net deferred tax liabilities resulting from the change in federal corporate income tax rate to 21 
percent from 35 percent effective January 1, 2018 as part of the 2017 Tax Act, partly offset by the increase in valuation allowance.

Our effective tax rate was 34.0 percent for 2016 as compared to 40.7 percent for 2015. The change in our tax rate reflects 
a shift in jurisdictional profitability between 2015 and 2016. Increased profits in 2016 within tax jurisdictions with tax rates lower 
than the United States resulted in a reduction to our effective tax rate. Our 2016 tax rate reflects the release of certain historical 
foreign reserve positions in Australia, primarily driven by a lapse of statute, as well as a reduction in our domestic production 
activities deduction as a result of lower taxable income in the United States.

The tax effects of temporary differences in the recognition of income and expense for tax and financial reporting purposes 
that  give  rise  to  significant  portions  of  the  deferred  tax  assets  and  the  deferred  tax  liabilities  are  presented  below:

The 2017 decrease in our net deferred tax liabilities resulted from the change in federal corporate income tax rate to 21 
percent from 35 percent effective January 1, 2018 as part of 2017 Tax Act, partly offset by current year activity. The Company 
also recorded  $34,462 as a reduction to net deferred tax liabilities  related to the finalization of purchase price accounting of the 
EFS acquisition. 

At December 31, 2017, the Company changed the tax structure of EFS to convert the limited liability company from a 
partnership to an entity disregarded as separate from its owners for federal tax purposes.  Accordingly, investment in partnership 
deferred tax liability was allocated to the deferred tax liabilities and assets related to the underlying assets, primarily intangibles. 
The Company had approximately $294,318 of post apportionment state, $112,688 of federal and $77,622 of foreign net operating 
loss  carry  forwards  at  December 31,  2017  and  approximately  $211,010  of  post  apportionment  state,  $103,739  of  federal  and 
$54,062 of foreign net operating loss carry forwards at December 31, 2016. The U.S. losses expire at various times through 2037. 
Foreign losses in Brazil and the UK have indefinite carry forward periods. 

At December 31, 2017, the Company maintained valuation allowances for the following items: (i) acquired and certain 
net operating losses in the UK (ii) Evolution1’s equity investment in its minority-owned subsidiaries, (iii) state tax credits, and 
(iv) certain net operating losses and estimated non-deductible expenses. In each case, the Company has determined it is not likely 
that the benefits will be utilized. No other valuation allowances have been established for any other deferred tax assets as the 
Company believes it is more likely than not that its deferred tax assets will be utilized within the carry forward periods. During 
2017 and 2016, the Company recorded tax expense of $12,167 and $2,000, respectively, for net increases to the valuation allowance. 
The substantial majority of the 2017 increase in valuation allowance was related to the state net operating losses for our parent 
company’s separate state filings.

At December 31, 2017, the Company had $4,859 of unrecognized tax benefits, net of federal income tax benefit, of which 
$3,944, if fully recognized, would decrease our effective tax rate. No significant changes to the existing unrecognized tax benefits 
are expected within the next 12 months. The Company recognizes interest and penalties related to unrecognized tax benefits in 
income tax expense. The Company recorded tax expense of $12 and $263 for interest and penalties related to uncertain tax positions 
for the years ended December 31, 2017 and December 21, 2015, respectively while a tax benefit of $2,251 was recorded for the 
year ended December 21, 2016. As of December 31, 2017 and 2016, the Company had no material amounts accrued for interest 
and penalties related to unrecognized tax benefits.

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits excluding interest and 

penalties is as follows:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

The Company’s primary tax jurisdictions are the United States, Australia and the United Kingdom. The Company or one 
of its subsidiaries files income tax returns in the United States federal jurisdiction and various state and foreign jurisdictions, where 
required. In the normal course of business, the Company is no longer subject to income tax examination after the Internal Revenue 
Service statute of limitations of three years. The Internal Revenue Service is currently in the process of examining the Company’s 
US federal income tax returns for 2010 through 2015.  The Company is currently appealing adjustments proposed by the Internal 
Revenue Service in connection with the ongoing audits.  The Company is also subject to an ongoing examination in New Zealand 
by Inland Revenue for calendar tax years 2013, 2014 and 2015, but no adjustments have been proposed, and the Company believes 
its position does not warrant a reserve.

15.

Tax Receivable Agreement

As a consequence of the Company’s separation from its former parent company in 2005, the tax basis of the Company’s 
net tangible and intangible assets increased (the “Tax Basis Increase”). The Tax Basis Increase reduced the amount of tax that the 
Company would pay in the future to the extent the Company generated taxable income in sufficient amounts. The Company was 
contractually obligated, pursuant to its 2005 Tax Receivable Agreement with the Company’s former parent company (Cendant 
Corporation), to remit 85 percent of any such cash savings. 

Pursuant to the Separation and Distribution Agreement dated as of July 27, 2006, by and among Cendant Corporation (now 
known as Avis Budget Group, Inc. or “Avis”), Realogy Corporation (“Realogy”), Wyndham Worldwide Corporation (“Wyndham”) 
and Travelport Inc., Realogy acquired from Cendant the right to receive 62.5 percent of the payments by WEX Inc. to Cendant 
and Wyndham acquired from Cendant the right to receive 37.5 percent of the payments by WEX Inc. to Cendant under the 2005 
Tax Receivable Agreement.

On June 26, 2009, the Company entered into a Tax Receivable Prepayment Agreement with Realogy, pursuant to which 
the Company paid Realogy $51,000, net of bank fees and legal expenses, as prepayment in full to settle the remaining obligations 
to Realogy under the 2005 Tax Receivable Agreement. In connection with the Tax Receivable Prepayment Agreement with Realogy, 
the Company entered into a Ratification Agreement on June 26, 2009 (the “Ratification Agreement”) with Avis, Realogy and 
Wyndham which amended the 2005 Tax Receivable Agreement to require the Company to pay 31.875 percent of the future tax 
savings related to the Tax Basis Increase to Wyndham.

The estimated amount of future payments owed to Wyndham is reflected as amounts due under tax receivable agreement 
on the consolidated balance sheets. The estimate is dependent upon future statutory tax rates and the Company’s ability to generate 
sufficient taxable income adequate to cover the tax depreciation, amortization and interest expense associated with the Tax Basis 
Increase. Estimated blended tax rates are impacted by a number of factors including tax law changes, statutory tax rate changes, 
state apportionment and state filing combinations. The Company regularly reviews its estimated blended tax rates and projections 
of future taxable earnings to determine whether changes in the estimated liability are required. Any changes to the estimated future 
payments  due  to  changes  in  estimated  blended  tax  rates  are  recorded  in  the  consolidated  statements  of  income  as  non-cash 
adjustments related to tax receivable agreement.

There has been a reassessment of the projected blended tax rates for each period presented. For the year ended December 31, 
2017, the net future benefits decreased, primarily as a result of the decline in Federal statutory tax rate as part of the 2017 Tax Act, 
which decreased the associated liability to Wyndham, resulting in a $15,259 offset to non-operating expense. In addition, the 
liability decreased due to payments of $11,769 made during the year ended December 31, 2017. For the year ended December 31, 
2016, the net future benefits increased, which increased the associated liability to Wyndham, resulting in a charge to non-operating 
expense of $563. In addition, the liability decreased due to payments of $10,797 made during the year ended December 31, 2016. 
For the year ended December 31, 2015, the net future benefits decreased, which decreased the associated liability to Wyndham, 
resulting in a $2,145 offset to non-operating expense. 

16.

Employee Benefit Plans

The Company sponsors a 401(k) retirement and savings plan. Eligible employees may participate in the plan immediately. 
The Company’s employees who are at least 18 years of age, have worked at least 1,000 hours in the past year, and have completed 
one year of service are eligible for Company matching contributions in the plan. The Company matches 100 percent of each 
employee’s  contributions  up  to  a  maximum  of  6  percent  of  each  employee’s  eligible  compensation. All  contributions  vest 
immediately. WEX Inc. has the right to discontinue the plan at any time. Contributions to the plan are voluntary. The Company 
contributed $6,710, $5,297 and $4,571 in matching funds to the plan for the years ended December 31, 2017, 2016 and 2015, 
respectively.

(in thousands, except per share data)

During 2016, the Company acquired EFS, which as of the date of the acquisition had its own employee savings plan (“the 
EFS Plan”). As of December 31, 2016, the EFS Plan was merged with the existing WEX plan, and the existing WEX plan recorded 
a receivable for the amount of net assets available for benefits expected to be received from the EFS Plan. On February 1, 2017, 
the WEX plan received net assets available for benefits totaling $15,159 in a transfer from the EFS Plan. On January 1, 2017, EFS 
employees became eligible to participate in the existing WEX plan. 

During 2014, the Company acquired Evolution1 which, as of the date of the acquisition, had its own employee savings 
plan, (“the Evolution1 Plan”). As of December 31, 2014, the Evolution1 Plan was merged with the existing WEX plan, and the 
existing plan recorded a receivable for the amount of net assets available for benefits it expected to receive from the Evolution1 
Plan.  Net  assets  available  for  benefits  totaling  $21,739  were  received  by  the  plan  on  January  2,  2015,  in  a  transfer  from  the 
Evolution1 Plan. On January 1, 2015, Evolution1 employees became eligible to participate in the existing WEX plan. 

The Company also sponsors a defined contribution plan for certain employees designated by the Company. Participants 
may elect to defer receipt of designated percentages or amounts of their compensation. The Company maintains a grantor’s trust 
to hold the assets under the Company’s defined contribution plan. The obligation related to the defined contribution plan totaled 
$6,798 and $5,673 at December 31, 2017 and 2016, respectively, and are included in other liabilities on the consolidated balance 
sheets. The assets held in trust are designated as trading securities and, as such, these trading securities are to be recorded at fair 
value with any changes recorded currently to earnings. The aggregate market value of the securities within the trust was $6,798
and $5,673 at December 31, 2017 and 2016, respectively, and are included in other assets on the consolidated balance sheets.

The Company has defined benefit pension plans in Germany and Norway. The total net unfunded status for the Company’s 
foreign defined benefit pension plans was $291 and $5,979 as of December 31, 2017 and 2016, respectively, recognized as accrued 
expenses in the consolidated balance sheets. The Company will measure these plan obligations on an annual basis. The change in 
fair value to the defined benefit pension plans is recorded through the consolidated statements of income. The expense under each 
of these defined benefit pension plans for 2017 and 2016 was not material to the consolidated financial statements.

We did not have any transfers between Level 1, Level 2 or Level 3 of the fair value hierarchy during the years ended 
December 31, 2017 and 2016. See Note 1, Summary of Significant Accounting Policies for a description of the levels of the fair 
value hierarchy.

Available-For-Sale Securities

When available, the Company uses quoted market prices to determine the fair value of available-for-sale securities; such 
inputs are classified as Level 1 of the fair-value hierarchy. These securities primarily consist of an open-ended mutual fund which 

100

 
 
 
 
 
  
 
 
Table of Contents

WEX INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

is invested in fixed-income securities and is held in order to satisfy the regulatory requirements of WEX Bank. For mortgage-
backed and asset-backed debt securities and bonds, the Company generally uses quoted prices for recent trading activity of assets 
with similar characteristics to the debt security or bond being valued. The securities and bonds priced using such methods are 
generally valued using Level 2 inputs. 

Executive Deferred Compensation Plan Trust

The obligations related to the deferred compensation plan trust are classified as Level 1 in the fair value hierarchy because 

the fair value is determined using quoted prices for identical instruments in active markets.

Interest Rate Swaps

The Company determines the fair value of its interest rate swaps based on the discounted cash flows of the difference 
between the projected fixed payments on the swaps and the implied floating payments using the current LIBOR curve, which are 
Level 2 inputs of the fair value hierarchy.

Notes Outstanding

On January 30, 2013, the Company completed an offering in an aggregate principal amount of $400,000 of 4.750 percent
senior notes due February 1, 2023, with interest payable semiannually. The Notes outstanding have a fair value of $410,000 and 
$390,000 as of December 31, 2017 and December 31, 2016, respectively. The fair value is based on market rates for the issuance 
of our debt. The Company determined the fair value of its Notes outstanding is classified as Level 2 in the fair value hierarchy. 

2016 Credit Agreement

The Company determines the fair value of the amount outstanding under its 2016 Credit Agreement based on the market 
rates for the issuance of the Company's debt which are Level 2 inputs in the fair value hierarchy. As of both December 31, 2017 
and 2016, the carrying value of the 2016 Credit Agreement approximated its fair value.

Commitments and Contingencies

Litigation

On August 11, 2016, the Company was sued in the Circuit Court of St. Charles County, Missouri, in a putative class action 
alleging the Company improperly sent unauthorized facsimile advertisements in violation of the Telephone Consumer Protection 
Act, 47 U.S.C. § 227 (the “TCPA”). The named plaintiff sought to represent a nationwide class of recipients of unauthorized 
facsimile advertisements from the Company (collectively, the "Plaintiffs") and requested statutory damages for each facsimile 
advertisement. The Plaintiffs further alleged that the opt-out notice of the faxes did not meet the criteria set forth in the TCPA or 
its underlying regulations. The Company removed the case to the United States District Court for the Eastern District of Missouri 
on September 15, 2016. On October 14, 2016, the Company filed an answer denying liability and stating the facsimile advertisement 
at issue was sent by FleetOne, LLC, the Company’s wholly-owned subsidiary. On May 10, 2017, the parties agreed to a settlement 
in principle to resolve the class claims, which was preliminarily approved by the court on October 6, 2017. The court entered its 
final judgment approving the settlement agreement on January 19, 2018. The settlement amount is not material to the Company's 
financial position, results of operations, cash flows or liquidity.

In addition, from time to time, we are subject to legal proceedings and claims in the ordinary course of business. As of 
the date of this filing, the current estimate of a reasonably possible loss contingency from all legal proceedings is not material to 
the Company's consolidated financial position, results of operations, cash flows or liquidity. 

Extension of Credit to Customers

The Company had aggregate unused commitments of approximately $6,300,000 and $5,400,000 at December 31, 2017
and 2016, respectively, related to payment processing services, primarily related to commitments to extend credit to customers 
and  customers  of  strategic  relationships  as  part  of  the  Company’s  established  lending  product  agreements.  Many  of  these 
commitments  are  not  expected  to  be  used;  therefore,  total  unused  credit  available  to  customers  and  customers  of  strategic 
relationships does not represent future cash requirements. The Company can increase or decrease its customers’ credit lines at its 
discretion at any time, subject to limited notice requirements in some instances. These amounts are not recorded on the consolidated 
balance sheets.

Operating Leases

The Company leases office space and equipment under non-cancelable operating lease agreements that expire at various 
dates through 2026. In addition, the Company rents office equipment under agreements that may be canceled at any time. Rental 
expense related to office space, equipment, and vehicle leases amounted to $15,471, $15,104 and $11,310 for the years ended 
December 31, 2017, 2016 and 2015, respectively. These amounts were included in occupancy and equipment on the consolidated 
statements of income. The Company leases information technology hardware and software under agreements that may be terminated 
by the Company at any time. Lease and rental expense related to information technology hardware and software leases totaled 
$8,765, $12,875 and $11,288 for the years ended December 31, 2017, 2016 and 2015, respectively. These amounts were included 
in technology leasing and support on the consolidated statements of income.

Future minimum lease payments under non-cancelable operating leases are as follows:

One of the Company's subsidiaries is required to purchase a minimum amount of fuel from suppliers on an annual basis 
through 2024. Should the Company fail to meet these minimum volume commitments, a penalty will be assessed as defined under 
the contracts. Starting in 2020, annual volume commitments reset based on prior year volume purchased. If the Company does 
not purchase fuel under these commitments after December 31, 2017, it would incur total penalties through 2019 totaling $362,856. 
During the year ended December 31, 2017, the Company incurred  $1,217 in shortfall penalties under these contracts. During the 
years ended December 31, 2016 and 2015, the Company did not incur material shortfall penalties under these contracts. The 
Company considers the associated risk of loss to be remote based on current operations.

The change in foreign currency items is primarily due to the foreign currency translation of non-cash assets such as 
goodwill and other intangible assets related to the Company's foreign subsidiaries. The total tax effect on foreign currency translation 
adjustments was $4,851 and $5,416 as of December 31, 2017 and 2016, respectively.

Dividend Restrictions

The Company has certain restrictions on the dividends it may pay under its revolving credit agreement, including pro 
forma compliance with a ratio of consolidated funded indebtedness to consolidated EBITDA of 2.50:1.00 for the most recent 
period of four fiscal quarters. However, if the Company's leverage ratio does not exceed 5.25 through September 30, 2017, 5.00 
through September 30, 2018, 4.50 through September 30, 2019, or 4.00 from December 31, 2019 and thereafter, after execution 

102

 
 
 
 
 
 
 
 
 
Table of Contents

WEX INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

of a restricted payment, the Company may pay $50,000 per annum for restricted payments, including dividends, of which 100%
of unused amounts may be carried over into subsequent years. The Company has not declared any dividends on its common stock 
since it commenced trading on the NYSE on February 16, 2005. 

Dividends paid by WEX Bank have provided a substantial part of the Company’s operating funds and for the foreseeable 
future it is anticipated that dividends paid by WEX Bank will continue to be a source of operating funds to the Company. Capital 
adequacy requirements serve to limit the amount of dividends that may be paid by WEX Bank. WEX Bank is chartered under the 
laws of the State of Utah and the FDIC insures its deposits. Under Utah law, WEX Bank may only pay a dividend out of net profits 
after it has (i) provided for all expenses, losses, interest and taxes accrued or due from WEX Bank and (ii) transferred to a surplus 
fund 10 percent of its net profits before dividends for the period covered by the dividend, until the surplus reaches 100 percent of 
its capital stock. For purposes of these Utah dividend limitations, WEX Bank’s capital stock is $5,250 and its capital surplus 
exceeds 100 percent of capital stock.

Under FDIC regulations, WEX Bank may not pay any dividend if, following the payment of the dividend, WEX Bank 
would be “undercapitalized,” as defined under the Federal Deposit Insurance Act and applicable regulations. The FDIC also has 
the authority to prohibit WEX Bank from engaging in business practices that the FDIC considers to be unsafe or unsound, which, 
depending on the financial condition of WEX Bank, could include the payment of dividends.

WEX Bank complied with the aforementioned dividend restrictions for each of the years ended December 31, 2017, 2016

and 2015.

21.

Stock-Based Compensation

In 2010, the Company adopted the WEX Inc. 2010 Equity Incentive Plan (the “Plan”), which replaced the Company’s 
2005  Equity  and  Incentive  Plan.  In  May  2015,  the  Company  adopted  the  2015  Section  162(m)  Performance  Incentive  Plan 
(collectively the “Plans”). The Plans, which are stockholder-approved, permit the grant of stock options, stock appreciation rights, 
restricted stock, restricted stock units and other stock-based or cash-based awards to non-employee directors, officers, employees, 
advisors or consultants. The Plans permit the Company to grant a total number of shares which is the sum of; (i) 3,800 shares of 
common stock; (ii) plus such additional number of shares of common stock (up to 1,596) that were reserved for issuance under 
the Company’s Amended and Restated 2005 Equity and Incentive Plan (the “Prior Plan”) that remained available for grant under 
the Prior Plan at the time the 2010 Plan was adopted. There were 1,617,334 units of common stock available for grant for future 
equity-incentive compensation awards under the Plan at December 31, 2017.

On December 31, 2017, the Company had four stock-based compensation award types, which are described below. The 
compensation cost that has been charged against income for these programs totals $30,487, $19,742 and $12,420 for 2017, 2016
and 2015, respectively. The associated tax benefit related to these costs was $7,347, $7,200 and $4,542, for 2017, 2016 and 2015, 
respectively.

Restricted Stock Units

The Company periodically grants restricted stock units (“RSUs”), which represent a right to receive a specific number 
of shares of the Company's common stock at a specified date, to non-employee directors and certain employees. RSUs granted to 
non-employee directors vest 12 months from the date of grant, or upon termination of board service if the director elects to defer 
receipt. RSUs issued to certain employees generally vest evenly over up to three years and provide for accelerated vesting if there 
is a change of control (as defined in the Plan). The fair value of each RSU award is based on the closing market price of the 
Company’s stock on the day of grant as reported by the New York Stock Exchange (“NYSE”).

The following is a summary of RSU activity during the year ended December 31, 2017:

to the appropriate taxing authority.

As of December 31, 2017, there was $9,613 of total unrecognized compensation cost related to RSUs. That cost is expected 
to be recognized over a weighted-average period of 1.3 years. The total grant-date fair value of RSUs granted was $11,700, $18,826
and $7,846 during 2017, 2016 and 2015, respectively. The total fair value of RSUs that vested during 2017, 2016 and 2015 was 
$7,310, $3,648 and $4,521, respectively.

Performance-Based Restricted Stock Units

The Company periodically grants performance-based restricted stock units (“PBRSUs”) to employees. A PBRSU is a 
right to receive stock based on the achievement of both performance goals and continued employment during the vesting period. 
In a PBRSU, the number of shares earned varies based upon meeting certain performance goals. PBRSU awards generally have 
performance goals spanning one to three years, depending on the nature of the performance goal. The fair value of each PBRSU 
award is based on the closing market price of the Company’s stock on the grant date as reported by the NYSE.

The following is a summary of PBRSU activity during the year ended December 31, 2017:

to be recognized over a weighted-average period of 1.9 years. The total grant-date fair value of PBRSUs granted during 2017, 
2016 and 2015 was $15,014, $15,921 and $6,860, respectively. The total fair value of PBRSUs that vested during 2017, 2016 and 
2015 was $15,948, $4,858 and $2,035, respectively.

Stock Options

Market Performance-Based Stock Options

In May 2017, the Company granted market performance-based stock options with a contractual term of ten years to 
members of senior management. The options contain a market condition that begins operating on the third anniversary of the grant 
date, requiring the closing price of the Company's stock to meet or exceed certain price thresholds for twenty consecutive trading 
days (“Stock Price Hurdle”) in order for shares to vest. In addition, award recipients must be continually employed from the grant 
date until such date that the Stock Price Hurdle is satisfied in order for shares to vest. To the extent both the service condition and 
the Stock Price Hurdles are not met by the end of a defined measurement period, these options will be canceled.

The grant date fair value of these options was estimated on the date of the grant using a Monte-Carlo simulation model 

used to simulate a distribution of future stock price paths based on historical volatility levels.

The table below summarizes the assumptions used to calculate the fair value:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
(in thousands, except per share data)

The Company will expense these options on a graded basis over the derived service period of approximately three years
regardless of whether the market condition is satisfied. Upon satisfaction of a Stock Price Hurdle, any unrecognized compensation 
expense for that specific tranche will be accelerated.

Service-Based Stock Options

Stock options granted to certain officers and employees under the Plan generally become exercisable over three years
(with approximately 33 percent of the total grant vesting each year on the anniversary of the grant date) and expire 10 years from 
the date of grant. 

Based on the Company's lack of historical option exercise experience and granting of stock options with "plain vanilla” 
characteristics, the Company uses the simplified method to estimate the expected term of its employee stock options. The fair 
value of each option award is estimated on the grant date using the following assumptions and a Black-Scholes-Merton option-
pricing model. The expected term assumption as it relates to the valuation of the options represents the period of time that options 
granted are expected to be outstanding. The Company also estimates expected volatilities that are based on implied volatilities 
from traded options on the Company's stock, historical volatility of the Company’s stock, and other factors. The option-pricing 
model includes a risk-free interest rate for the period matching the expected term of the option and is based on the U.S. Treasury 
yield curve in effect at the time of the grant. The dividend yield used in the option-pricing model is the calculated yield on the 
Company’s stock at the time of the grant.

years ended December 31, 2017, 2016 and 2015 was $642, $1,712 and $216, respectively. The total grant-date fair value of options 
granted during 2017, 2016 and 2015 was $20,516, $3,297, and $1,855, respectively. 

Deferred Stock Units

Non-employee directors may elect to defer their cash fees and RSUs in the form of deferred stock units ("DSUs"). The 
Company  previously  granted  non-employee  directors  fully  vested  RSUs. These  awards  were  fully  vested  upon  grant  and  are 
distributed as common stock on the date which is 200 days immediately following the date upon which such director’s service as 
a member of the Company’s Board of Directors terminates for any reason. There were approximately 94 and 101 DSUs outstanding 
as of December 31, 2017 and 2016, respectively. Unvested DSUs as of December 31, 2017 and 2016 were not material.

Impairment and Restructuring Activities

Impairment Charges and Asset Write-Offs

Following  the  acquisition  of AOC  in  the  fourth  quarter  of  2017,  the  Company  reevaluated  software  currently  under 
development for payment processing within our Travel and Corporate Solutions segment. From this, we determined the developed 
technology obtained in the AOC acquisition more closely aligns with our technological strategy. As result, approximately $22,000
of software under development was determined to have no future benefit and therefore impaired during the year ended December 
31, 2017. We also impaired approximately $6,000 of computer software within the Fleet Solutions segment in 2017 as a result of 
our ongoing platform consolidation strategy, designed to ensure we continue to deliver superior technology to our customers.

During the year ended December 31, 2017, the Company executed a vendor contract amendment based on a strategic 
decision to in-source certain previously outsourced technology functions. As a result of this action, the Company determined that 
approximately $16,000 of prepaid services had no future benefit and were therefore written off within the Fleet Solutions segment 
during the same period.

Restructuring

In the first quarter of 2015, the Company commenced a restructuring initiative (the “2015 Restructuring Initiative”) as a 
result of its global review of operations. The review of operations identified certain initiatives to further streamline the business, 
to improve the Company's efficiency, and to globalize the Company's operations, all with an objective to improve scale and increase 
profitability going forward. The Company continued its efforts to improve its overall operational efficiency and began a second 
restructuring  initiative  (the  “2016  Restructuring  Initiative”)  during  the  second  quarter  of  2016.  In  connection  with  the  EFS 
acquisition, the Company initiated a restructuring program in the third quarter of 2016 (the “Acquisition Integration Restructuring 
Initiative”). 

The restructuring expenses related to these initiatives primarily consist of employee costs and office closure costs directly 
associated  with  the  respective  programs. The  Company  has  determined  the  amount  of  expenses  related  to  these  initiatives  is 
probable and reasonably estimable. As such, it has recorded the impact on the consolidated statements of income and in accrued 
expenses on the consolidated balance sheets. Restructuring charges incurred to date under these initiatives were $24,479 as of 
December 31, 2017.

The balances under these initiatives are expected to be paid through 2018. Based on current plans, which are subject to 

change, the amount of additional restructuring costs that the Company expects to incur is immaterial. 

The following table presents the Company's 2015 Restructuring Initiative liability:

Segment Information

Operating segments are defined as components of an enterprise about which separate financial information is available 
and is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and assess 
performance. The Company's CODM is its Chief Executive Officer. The operating segments are aggregated into the three reportable 
segments described below. 

•  Fleet Solutions provides customers with payment and transaction processing services specifically designed for the needs 
of  commercial  and  government  fleets.  This  segment  also  provides  information  management  services  to  these  fleet 
customers.

• 

Travel  and  Corporate  Solutions  focuses  on  the  complex  payment  environment  of  business-to-business  payments, 
providing customers with payment processing solutions for their corporate payment and transaction monitoring needs. 

•  Health and Employee Benefit Solutions provides healthcare payment products and SaaS consumer directed platforms, as 

well as payroll related benefits to customers. 

During the third quarter of 2017, the Company revised its operating segment measurement from adjusted  pre-tax income 
to adjusted operating income. The Company no longer allocates financing interest expense to our operating segments as management 
believes this item can obscure underlying business trends. As such, we believe adjusted operating income reflects an enhanced 
measurement of segment profitability. Segment results for the years ended December 31, 2016 and 2015 have been revised to 
reflect this change in operating segment measurement.

Adjusted operating income adjusts operating income to exclude: (i) acquisition and divestiture related items (including 
acquisition-related  intangible  amortization);  (ii)  stock-based  compensation;  (iii)  restructuring  and  other  costs;  (iv)  gains  on 
divestitures; (v) debt restructuring costs (vi) reserves for regulatory penalties, (vii) impairment charges and asset write-offs. For 
the year ended December 31, 2016, adjusted operating income excluded a vendor settlement.

The accounting policies of the reportable segments are generally the same as those described in the summary of significant 

accounting policies. Assets are not allocated to the segments for internal reporting purposes.

The following tables present the Company’s reportable segment results on an adjusted operating income basis for the 

years ended December 31, 2017, 2016 and 2015:

The Company's subsidiary, WEX Bank is subject to various regulatory capital requirements administered by the FDIC 
and the Utah Department of Financial Institutions. Failure to meet minimum capital requirements can initiate certain mandatory,

and possible additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company’s 
financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, WEX Bank 
must meet specific capital guidelines that involve quantitative measures of WEX Bank’s assets, liabilities, and certain off-balance-
sheet items as calculated under regulatory accounting practices. WEX Bank’s capital amounts and classification are also subject 
to qualitative judgments by the regulators about components, risk weightings, and other factors. 

Quantitative measures established by regulation to ensure capital adequacy require WEX Bank to maintain minimum 
amounts and ratios as defined in the regulations. As of December 31, 2017 and December 31, 2016, the most recent FDIC exam 
report categorized WEX Bank as “well capitalized” under the regulatory framework for prompt corrective action. There are no 
conditions or events subsequent to that examination report that management believes have changed WEX Bank’s capital rating.

On January 17, 2018, the Company further repriced the secured term loans under the 2016 Credit Agreement, which 
reduced the applicable interest rate margin for the Company’s tranche B term loans by 50 basis points for both LIBOR borrowings 
and base rate borrowings, increased the outstanding amounts on these tranche B term loans from $1.182 billion to $1.335 billion, 
and made certain other changes to the 2016 Credit Agreement, including increasing the maximum consolidated leverage ratio for 
the period of December 31, 2018 through September 30, 2019 and upon the occurrence of an acquisition meeting certain specified 
criteria, permitting the incurrence of unsecured indebtedness as long as the Company is in pro forma compliance with the financial 
covenants, resetting the six month soft call period for a repricing of the tranche B term loans and resetting and amending the test 
for incremental loans. Following the repricing, the applicable interest rate margin for the tranche B term loans was set at 2.25%
for LIBOR borrowings and 1.25% for base rate borrowings. The Company incurred approximately $6 million of expenses upon 
the closing of this repricing.

 CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The principal executive officer and principal financial officer of WEX Inc. evaluated the effectiveness of the Company’s 
disclosure controls and procedures as of the end of the period covered by this report. “Disclosure controls and procedures” are 
controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company 
in the reports that it files or submits under the Securities Exchange Act of 1934, within the time periods specified in the SEC’s 
rules  and  forms,  is  recorded,  processed,  summarized  and  reported,  and  is  accumulated  and  communicated  to  the  company’s 
management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions 
regarding required disclosure. Based on their evaluation, the principal executive officer and principal financial officer of WEX 
Inc. concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2017.

Management’s Annual Report on Internal Control Over Financial Reporting

WEX Inc.'s management is responsible for establishing and maintaining adequate internal control over financial reporting. 
Internal control over financial reporting is defined in Rule 13a-15(f) promulgated under the Exchange Act as 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 accounting principles generally accepted in the United States of America. Internal control 
over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions and 
disposition of assets; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial 
statements; providing reasonable assurance that receipts and expenditures are made only in accordance with management and 
Board authorizations; and providing reasonable assurance regarding prevention or timely detection of unauthorized acquisition, 
use or disposition of our assets that could have a material effect on our financial statements.  Because of its inherent limitations, 
internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements 
would be prevented or detected. 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.

Under the supervision and with the participation of management, including the principal executive officer and principal 
financial and accounting officer, an evaluation was conducted of the effectiveness of the internal control over financial reporting 
based on the framework in Internal Control - Integrated Framework (2013) issued by The Committee of Sponsoring Organizations 
of the Treadway Commission. Based on our evaluation under the framework in Internal Control - Integrated Framework (2013), 
management concluded that WEX Inc.’s internal control over financial reporting was effective as of December 31, 2017. The 
effectiveness of our internal control over financial reporting as of December 31, 2017, has been audited by Deloitte & Touche 
LLP, an independent registered public accounting firm, as stated in their attestation report which is included herein.

Changes in Internal Control Over Financial Reporting

In  the  course  of  completing  its  assessment  of  internal  control  over  financial  reporting  as  of  December  31,  2016, 
management identified a number of deficiencies related to the design and operating effectiveness of information technology (“IT”) 
general controls for certain information systems that comprise part of the Company’s system of internal control over financial 
reporting and are relevant to the preparation of its consolidated financial statements (such information technology systems are 
referred to as the “affected IT systems”). These deficiencies involved user access controls and program change management 
controls.  These controls are intended to ensure that access to financial applications and data is adequately restricted to appropriate 
personnel, and that changes affecting the financial applications and underlying account records are made by only authorized 
individuals. 

As a result of the deficiencies identified as of December 31, 2016, management concluded that, as of December 31, 2016, 
there was a material weakness in internal control over financial reporting related to information technology general controls in 
the areas of user access and program change management for the affected IT systems. A material weakness is a deficiency, or a 
combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material 
misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

113

 
 
 
 
 
Table of Contents

Over  the  course  of  2017,  we  actively  engaged  in  the  implementation  of  a  remediation  plan  to  ensure  that  controls 
contributing to this material weakness were redesigned appropriately and would operate effectively in the future.   The remediation 
actions taken included the following:

• 

Improving the design, operation and monitoring of control activities and procedures associated with user and administrator 
access to the affected IT systems, through the implementation of preventive and detective control activities;

•  Redesigning and implementing detective monitoring controls within IT to directly mitigate the risks;

•  Enhancing resources in the functional areas that support and monitor our IT controls; and

•  Exercising direct performance of the controls related to effected IT systems.

Based upon the actions taken during 2017, which were substantially completed in the fourth quarter of 2017, and our 
testing and evaluation of the effectiveness of our internal control over financial reporting, we have concluded that the material 
weakness in internal control over financial reporting related to information technology general controls no longer existed as of 
December 31, 2017.

Other than the changes discussed above, there has been no change in our internal control over financial reporting during 
the quarter ended December 31, 2017, that has materially affected, or is reasonably likely to materially affect, our internal control 
over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Stockholders of WEX Inc.
South Portland, Maine

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of WEX Inc. and subsidiaries (the “Company”) as of December 31, 
2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective 
internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated 
Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the consolidated financial statements as of and for the year ended December 31, 2017, of the Company and our report 
dated March 1, 2018, expressed an unqualified opinion on those financial statements. 

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 appearing at Item 9A. 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.
