PART I

ITEM 1. BUSINESS

Our Company

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, Wright Express was sold to Avis Group Holdings, Inc., which was acquired by Cendant in March 2001. In anticipation of our IPO, the Company’s operations were transferred to a Delaware LLC, which was converted into a Delaware corporation in 2005 in conjunction with our IPO. For over the past 30 years, we have expanded the scope of our business into a multi-channel provider of corporate payment solutions.

WEX Inc. has been publicly traded since February 16, 2005 (NYSE:WEX) and currently operates in two business segments: Fleet Payment Solutions and Other Payment Solutions. Our business model enables us to provide exceptional payment security and control across a wide spectrum of payment sectors. The Fleet Payment Solutions segment provides customers with fleet vehicle payment processing services specifically designed for the needs of commercial and government fleets. Fleet Payment Solutions revenue, which represented approximately 74 percent of our total revenue during the year ended December 31, 2013, is earned primarily from payment processing, account servicing and transaction processing, with the majority generated by payment processing. As of December 31, 2013, the Fleet Payment Solutions segment services over 7.7 million vehicles. Management estimates that WEX fleet cards are accepted at over 90 percent of fuel locations in each of the United States ("U.S.") and Australia. The Other Payment Solutions segment provides customers with payment processing solutions for their corporate payment and transaction monitoring needs. Other Payment Solutions revenue, which represented approximately 26 percent of our total revenue during the year ended December 31, 2013, is earned primarily from payment processing revenue from our virtual card product. The Other Payment Solutions segment has operations in North America, Europe, Australia and Brazil.

1

The Company’s U.S. operations include WEX Inc. and rapid! PayCard and our wholly-owned subsidiaries Fleet One, WEX Bank, and Pacific Pride. Our international operations include our wholly-owned subsidiaries, WEX Fuel Cards Australia (formerly Wright Express Fuel Cards Australia,) WEX PrePaid Cards Australia (formerly Wright Express Prepaid Cards Australia), WEX New Zealand (formerly Wright Express New Zealand), WEX Europe Services, WEX Europe (formerly CorporatePay Limited), located in England, and a majority equity position in UNIK S.A., a Brazil-based company.

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 recent acquisitions include the following transactions:

• On October 15, 2013, UNIK S.A. acquired FastCred, a provider of fleet cards to the heavy truck or over-the-road segment of the fleet market in Brazil.

• On October 4, 2012, we acquired Fleet One, a provider of fleet cards and fleet-related payment solutions to the over-the-road segment of the fleet market.

• On August 30, 2012, we acquired a 51 percent controlling interest in UNIK S.A., a provider of payroll cards, private label and processing services in Brazil, specializing in the retail, government and transportation sectors. We have an option to acquire the remaining shares of UNIK S.A.

• On May 11, 2012, we acquired CorporatePay Limited, located in London, England, a provider of corporate prepaid solutions to the travel industry in the United Kingdom. CorporatePay offers direct, co-branded and private label solutions including virtual cards, currency cards and expense management solutions.

In addition to the transactions described above, on November 8, 2013, we announced plans to acquire the assets of ExxonMobil’s European commercial fuel card program through a 75 percent majority owned subsidiary, WEX Europe Services Limited. The anticipated transaction is subject to completion of the employee information and consultation processes, and obtaining of competition authority approvals, as appropriate.

WEX Bank, a Utah industrial bank incorporated in 1998, is a Federal Deposit Insurance Corporation (“FDIC”) insured depository institution. WEX Bank’s primary regulators are the Utah Department of Financial Institutions and the FDIC. WEX Bank is required to maintain elements of independence from the rest of our business to comply with its charter and applicable banking regulations, and is required to file separate financial statements with the FDIC. The activities performed by WEX Bank are integrated into the operations of both of the Company’s segments. The functions performed at WEX Bank contribute to the operations of both of WEX’s segments 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 deposits and negotiable order of withdrawal (“NOW”) accounts and provides the financing and makes the credit decisions that enable both 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. 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.

Competitive Strengths

We believe the following strengths distinguish us from our competitors:

Fleet Payment Solutions

• We believe our 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” as 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 believes provides over 90 percent fuel location coverage in each of the U.S. and Australia, as well as wide acceptance in Canada and Brazil, which provides our customers with the convenience of broad acceptance.

• Our proprietary closed-loop fuel networks also 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 allows us to improve and refine the information reporting we provide to our fleet customers and customers of our strategic relationships.

2

• 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 proprietary software facilitates the collection of information and provides us with a high level of control and flexibility in allowing fleets to restrict purchases and receive automated alerts.

• 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 7.7 million vehicles serviced as of December 31, 2013 and co-branded strategic relationships with six of the largest U.S. fleet management companies and with numerous 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 98 percent (based on the 2013 rate of voluntary customer attrition).

• Our proprietary closed-loop network is a significant barrier to entry because a competitor would need to establish a direct relationship with each of the merchants that comprise the network.

• Our entrance into the over-the-road segment of the market, as bolstered by the acquisition of Fleet One in 2012, enhances 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.

Other Payment Solutions

• Our virtual payment products offer corporate customers enhanced security and control for complex payment needs. Our strategic relationships include three of the largest U.S. based online travel agencies. Our operations in the United Kingdom provide corporate prepaid solutions to the travel industry. We have expanded our online travel capabilities and geographies, including Asia-Pacific, South America and Europe and settle transaction in over 14 currencies. Additionally, we offer virtual products in the insurance/warranty and healthcare markets in the United States.

• We offer paycard products in the U.S. and Brazil. These products include payroll cards which are used to replace paper payroll checks. This is a service offered by businesses to individuals who often do not have a bank account.

Other Competitive Strengths

• The demand for our payment processing, account servicing and transaction processing services combined with significant operating leverage has historically driven strong revenue growth with consistently high margins. 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 and card placement. 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.

• We have an enterprise-wide risk management program that helps us to effectively address inherent risks related to funding and liquidity, fuel price volatility, our 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 use fuel price derivatives to manage a portion of our U.S. fuel-price-related earnings exposure, as described below under “Fuel Price Derivatives.” We have historically maintained a long record of low credit losses due to the short-term, non-revolving credit issued to our customer base, which is typically due within 30 days. Our credit risk management program is enhanced by our proprietary scoring model, reducing credit lines and early suspension policy. As of December 31, 2013, 95 percent of accounts receivables were less than 30 days past due and 99 percent were less than 60 days past due. Interest rate risk is managed through diversified funding sources at WEX Bank with significant non-interest bearing liabilities and merchant contracts that include some ability to raise rates if interest rates rise.

3

• We have an experienced and committed management team that has substantial industry knowledge and a proven track record of financial success. Our executive management team has significant industry experience and an average of over 10 years of tenure with us. The team has been successful in driving strong growth in our business and establishing a track record of strong, consistent operating performance. We believe that our management team positions us well to continue to successfully implement our growth strategy and capture operating efficiencies.

Strategy

As we cultivate our Company’s path forward, there are three key priorities for 2014: 

• Position the Company to accelerate growth organically and through mergers and acquisitions.  We intend to continue to grow our business organically through the use of our various marketing channels, leveraging our competitive advantages and continuing to explore new strategies that bring innovative new products to market.  The Company’s merger and acquisition strategy is focused on creating and enhancing scale in our business and adding product differentiation and functionality that improves our offering, primarily in the fleet and travel markets. 

• Focus on further globalizing our business by making targeted investments. Investments are core to achieving our growth objectives over the near and long term.  An example of this is our recently announced plans to acquire the Esso commercial fuel card portfolio in Europe.  We are also continuing to invest in our issuing and settlement capabilities internationally for virtual payments, specifically to service online travel agencies. 

• Drive scale across the organization. We will operate with systemic efficiency by allocating and optimizing resources to drive the greatest results and volume across market segments.  

FLEET PAYMENT SOLUTIONS SEGMENT

Overview

The Fleet Payment 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 7.7 million vehicles, as of December 31, 2013, 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 unique financing model with attractive credit terms. Our fleet products are based upon proprietary technology with closed-loop networks in the U.S. and Australia, 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 Payment 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. 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 payment processing transaction:

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. In 2013, we processed approximately 292 million payment processing transactions, compared to 261 million payment processing transactions in 2012.

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 24

5

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.

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, through our website, can access their account information, including account history and recent transactions, and download the details. In addition, through our websites, 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 directly 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. Our direct line of business services 3.5 million vehicles.

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 oil merchants 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. Our co-branded marketing channel services 1.8 million vehicles.

Our private label programs market our product 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. Our private label marketing channel services 2.4 million vehicles.

Fuel Price Derivatives

Management estimates approximately 42 percent of our total revenue in 2013 resulted from fees paid to us by fuel providers based on a negotiated percentage of the purchase price of fuel purchased by our customers and accordingly was impacted by fuel prices. To address these fluctuations, we hedge, and expect to continue to hedge, approximately 60 percent of our U.S. fuel-price-related earnings exposure to improve management of potential cash flow volatility created by changes in U.S. fuel prices and to enhance the visibility and predictability of our future cash flows. Prior to 2012, we entered into hedges intended to cover approximately 80 percent of our U.S. fuel-price-related earnings exposure.

Our hedging program uses put and call option contracts with monthly settlement provisions that create a “costless collar” based upon both the U.S. Department of Energy’s weekly diesel fuel price index and the NYMEX unleaded gasoline contracts. When entering into these options, our intent is to effectively lock in a range of prices during any given quarter on a portion of our U.S. forecasted earnings that are subject to fuel price variations. Differences between the indices underlying the options and actual retail prices may create a disparity between the effects of price changes on the actual revenues we earn and the gains or losses realized on the options.

6

Our derivative instruments do not qualify for hedge accounting under accounting guidance. Accordingly, gains and losses on our fuel price-sensitive derivative instruments, whether they are realized or unrealized, affect our current period earnings.

The options are intended to limit the impact fuel price fluctuations have on our cash flows. The options that we have entered into:

Create a floor price.  When the current month put option contract settles, we receive cash payments from the counterparties if the average price for the current month (as defined by the option contract) is below the strike price of the put option.

Create a ceiling price.  When the current month call option contract settles, we make cash payments to the counterparties if the average price for the current month (as defined by the option contract) is above the strike price of the call option.

When the current month put and call option contracts settle and the average price for the current month (as defined by the option contract) is between the strike price of the put option contract and the strike price of the call option contract, no cash is exchanged between the counterparties and us.

The following table presents information about the options as of December 31, 2013. The approximate percentage of hedged fuel price-sensitive earnings exposure includes the earnings from our Fleet One operations.

	Q1	Q2	Q3	Q4	Q1	Q2
	2014	2014	2014	2014	2015	2015
Average low end of range of fuel prices per gallon	$3.38	$3.36	$3.37	$3.34	$3.32	$3.34
Average top end of range of fuel prices per gallon	$3.44	$3.42	$3.43	$3.40	$3.38	$3.40
Approximate % of exposure locked in	60%	60%	60%	60%	40%	20%

OTHER PAYMENT SOLUTIONS SEGMENT

Overview

Our Other Payment Solutions segment is comprised of our virtual and paycard products where we provide innovative corporate purchasing capabilities which can be integrated with our customers’ internal systems to streamline their payroll, accounts payable and reconciliation processes.

Products and Services

Virtual Card Products

The WEX virtual card product suite allows businesses to centralize purchasing, simplify complex supply chain processes and eliminate the paper check writing associated with traditional purchase order programs. 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. Our virtual card programs consist of:

• WEX Travel - Since 2000, travel wholesalers and resellers have used WEX to deliver efficiencies through precise payment control and reconciliations. 

• WEX Health - Healthcare companies are embracing the migration to electronic payments as a strategic move to streamline processes and reduce costs. 

• WEX Insurance - WEX’s electronic claims solution allows auto claim payment to preferred and out-of-network suppliers.

• WEX Education - WEX virtual payment solutions facilitate streamlining of the payment process and reduction of costs.

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.

The following illustration depicts our business process for a typical virtual card transaction in the travel industry:

Paycard Products

Paycard products are an emerging product line for WEX Inc. The rapid! PayCard product, a pre-paid payroll card, provides a comprehensive paycard benefit and ePayroll program designed for employers choosing to convert to electronic delivery of payroll in the United States, replacing paper employee payroll checks. Additionally, we own a 51 percent controlling interest in UNIK S.A., a provider of employee benefit cards, private label and processing services in Brazil, specializing in the retail, government and transportation sectors.

Prepaid and gift cards

WEX Prepaid Card Australia offers prepaid and gift cards products to companies throughout Australia. 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.

Marketing Channels

We market our Other Payment Solutions segment products and services directly to our customers in conjunction with our fleet offerings, as well as to potential new clients with whom we have no existing relationship. Our corporate purchase products are marketed to commercial and government organizations and we use existing open-loop networks. Our rapid! PayCard product is marketed to small and medium sized businesses in the United States.

OTHER ITEMS

Employees

As of December 31, 2013, WEX Inc. and its subsidiaries had 1,431 employees, of which 1,201 were located in the United States. None of our employees are subject to a collective bargaining agreement.

Competition

We have a strong competitive position in our Fleet Payment Solutions and Other Payment Solutions segments. Our product features and extensive account management services are key factors behind our position in the fleet industry. We face competition in both 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

8

cards currently compete against us primarily in the local fleet category of our Fleet Payment Solutions segment and in the corporate purchase card category of our Other Payment Solutions segment.

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 difficult for us to maintain profit margins at historical levels.”

Seasonality

Our businesses are affected by seasonal variations as fuel prices are typically higher during the summer and online travel sales are typically higher during the third quarter. However, this seasonality does not have a material impact on our financial results.

Technology

We believe that investment in technology is a crucial step in maintaining and enhancing our competitive position in the marketplace. In the United States, our fleet fuel-based closed-loop proprietary software captures detailed information from the fuel and maintenance locations within our network. Operating a proprietary network not only enhances our value proposition, it enables us to limit dependence on third-party processors and to respond rapidly to changing customer needs with system upgrades, while maintaining a secure environment. 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.

In Australia, New Zealand, Brazil and the United Kingdom, we use standalone platforms to support operations. All of the development, maintenance and support of each card management system are performed within the respective business. We continue to invest in our infrastructure.

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. For information regarding technology related risks, see the information in Item 1A under the headings “We may not be able to adequately protect 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” and “We are dependent on technology systems and electronic communications networks managed by third parties, which could result in our inability to prevent service disruptions.”

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 and Fleet One brand names in the U.S., the MotorPass and Motorcharge brand names in Australia and the UNIK S.A. brand name in Brazil.

Regulation - United States

The Company and WEX Bank are subject to certain state and federal laws and regulations governing insured depository institutions and their affiliates. The Company and WEX Bank, as well as its subsidiaries are subject to supervision and examination by both the Utah Department of Financial Institutions and the FDIC. The Company and its affiliates are subject to certain restrictions 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.

Exemption from certain requirements of the Bank Holding Company Act

9

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 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 bar 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 requires 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, or the offering of a consumer financial product or service. The CFPB has broad rulemaking authority for a wide range of consumer protection laws, including the authority to prohibit “unfair, deceptive or abusive” acts and practices. The legislation also gives the state attorneys general the ability to enforce applicable federal consumer protection laws.

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 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 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 (“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.

10

Under the Financial Services Modernization Act of 1999, also referred to as the “Graham-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 the laws in the conduct of its business.

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 restrict such entity’s ability to vote shares held by it.”

Regulation - Foreign

The conduct of our businesses, and the use of our products and services are subject to various foreign laws and regulations administered by government entities and agencies where we operate. It is our policy to abide by the applicable laws and regulations in the jurisdictions around the world in which we do business.

Australia

The Company’s Australian operations are subject to laws and regulations of the Commonwealth of Australia governing banking and payment systems, financial services, consumer credit and money laundering. Because neither WEX Fuel Cards Australia nor 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.

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 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. Brazil’s labor systems are governed by the Consolidation of Brazilian Labor Laws. Brazil is a signatory of the World Trade Organization’s

11

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 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.

As of December 31, 2013, management estimates approximately 42 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. Our customers primarily purchase fuel. Accordingly, part of our revenue is dependent on fuel prices, which are prone to volatility. For example, we estimate that during 2013, a one cent decline in average fuel prices below average actual prices would have resulted in approximately a $0.8 million decline in 2013 revenue. Declines in the price of fuel could have a material adverse effect on our total revenues.

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;

• 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;

12

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

• general worldwide economic conditions; and

• governmental regulations and tariffs.

Derivative transactions may not adequately stabilize our cash flows and may cause volatility in our earnings.

Because a significant portion of our revenues are subject to fuel price volatility, we utilize fuel price sensitive derivative instruments to manage our exposure to this volatility in North America by seeking to limit fluctuations in our cash flows. For a more detailed discussion of these derivative instruments see our “Fuel Price Derivatives” discussion in Item 1. Business. These instruments may expose us to the risk of financial loss if, for example, we unwind our position before the expiration of the contract or there is a significant change in fuel prices. The success of our fuel price derivatives program depends upon, among other things, our ability to forecast the amount of fuel purchased by fleets using our services in the U.S. and the percentage based fee we will earn from merchants. To the extent our forecasts are inaccurate these derivative contracts may be inadequate to protect us against significant changes in fuel prices or over-expose us to fuel price volatility. Realized and unrealized gains and losses on these contracts are recorded each quarter to reflect changes in the market value of the underlying contracts. As a result, our quarterly net income may be prone to significant volatility.

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

We are subject to the credit risk of our customers, many of which are small-to mid-sized businesses. We use various formulas and models to screen potential customers and establish appropriate credit limits, but these formulas and models cannot eliminate all potential bad 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 become bad credit risks over time and we may fail to detect such change. 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.

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

We engage in a number of transactions where counterparty credit risk is a relevant factor. Specifically, we have fuel price derivatives whose values at any point in time are dependent upon not only the market but also the 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 these situations. Financial institutions, primarily banks, have historically been our most significant counterparties.

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 Act 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 require federal agencies to adopt implementing regulations which have not been completed and because many of its provisions are being phased in over time. 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. For example, the Dodd-Frank Act provides the Commodity Futures Trading Commission with broad authority to adopt combined position limits for futures contracts and over-the-counter derivatives. We cannot assess whether those rules, which have been vacated by a U.S. District Court and are the subject of continuing litigation, if eventually upheld, would have an adverse impact on our business.

Although the application of the Dodd-Frank Act’s provisions to us, if any, are uncertain at this time, we could be required to change our fuel price hedging practices 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 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.

If we modify or reduce our use of derivatives as a result of the legislation and regulations, our results of operations may become more volatile and our cash flows may be less predictable. Increased volatility may make us less attractive to

13

certain types of investors. Any of these consequences could have a material adverse effect on our financial condition and results of operations.

The Dodd-Frank Act also created the Consumer Financial Protection Bureau, or 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 will enforce those laws against and examine 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 Dodd-Frank Act and any related legislation or regulations may have a material impact on our business, results of operations and financial condition. In addition, 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.

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.

We had $685 million of fixed and variable interest rate indebtedness outstanding at December 31, 2013, consisting of $400 million of borrowings under our bond facility at a fixed rate of 4.750% and $285 million of borrowings under our senior secured credit facility that bore interest at a floating rate equal to the one-month LIBOR plus 175 basis points. An increase in interest rates would increase the cost of borrowing under our senior secured credit facility.

Our industrial bank subsidiary, WEX Bank, uses certificates of deposit and interest-bearing money-market deposits, or collectively brokered deposits, as well as NOW accounts, to finance payments to major oil companies. Certificates of deposit carry fixed interest rates from issuance to maturity. 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, 2013, WEX Bank had outstanding $453.5 million in certificates of deposit maturing within one year, $117.9 million in certificates of deposit maturing within one to two years, and $222.5 million in interest-bearing money market deposits. Also at December 31, 2013, WEX Bank had $276.4 million of NOW account deposits outstanding, which are currently non-interest bearing.

We have substantial indebtedness, which may materially and adversely affect our financial flexibility and our ability to meet our debt service obligations under our 4.750% senior notes, due 2023 (the “notes”).

Our indebtedness consists of secured indebtedness under our 2013 Amended and Restated Credit Agreement ("2013 Credit Agreement"), 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.

14

There can be no assurance that we will be able to meet our debt service 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 our 2013 Credit Agreement we are required to remain in compliance with a maximum consolidated leverage ratio and a consolidated interest coverage ratio and other covenants. If our earnings decline, or if we incur additional indebtedness, we may be unable to comply with these financial ratios. Failure to comply with the financial covenants or any other non-financial or restrictive covenant in our 2013 Credit Agreement could create a default under our 2013 Credit Agreement. Upon a default, our lenders could accelerate the indebtedness under the facilities, 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 2013 Credit Agreement, we may incur additional indebtedness, which could increase the risks associated with our already substantial indebtedness. Subject to certain limitations, we have the ability to borrow additional funds under our 2013 Credit Agreement, including compliance with the covenants in our 2013 Credit Agreement.

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 cannot assure 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 2013 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.

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.

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 23 percent of our total revenues in 2013. Accordingly, we are dependent on maintaining our strategic relationships and our results of operations would be lower in the event that any of relationships cease to exist. Likewise, we have agreements with the major oil companies and fuel retailers 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. In addition, as of December 31, 2013, we had $276.4 million of NOW account deposits outstanding with a single program. If that relationship terminated, we would need to seek additional sources of funding or further utilize other existing sources of funding. There could be no assurance that we would be able to find new or use existing sources of funding on terms acceptable to us. If we were unable to secure such funding, our results of operations could be adversely affected.

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 any acquired 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.

15

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:

• 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;

• local labor conditions and regulations; and

• fluctuation in foreign currencies.

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.

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, law or regulation 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 negatively impact our business. These factors could significantly and adversely affect our business, financial condition and results of operations.

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 industry is 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 regulations; compliance obligations; data security and data breach requirements; identity theft avoidance programs; 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 and financial condition and results of operations and further increase compliance costs and limit our ability to expand to new markets.

We also conduct business with other highly regulated businesses such as banks and payment card issuers. There continues to be significant potential reforms that could negatively affect their businesses, ability to maintain or expand their products and services, and the costs associated with doing so. These developments could also negatively impact our business.

16

The acquisition of the ESSO Card program may have a significant impact on our business and results of operation.

In November 2013 we announced our plans to acquire the assets of ExxonMobil's’ European commercial card program. The transaction is expected to close in late 2014 or early 2015 and upon its completion, we expect that this portfolio will contribute approximately $35 million in annual revenue. While this transaction is a significant milestone for us, we expect to make significant investments to integrate the Esso Card into our operations and systems. If we fail to complete the work necessary to support the integration, we may face project management and execution risks and may take longer than expected and delay when and if we realize the revenue from this transaction. This work may also impact our existing operations as resources are utilizes to support the ESSO Card integration and maintain the projected schedule.

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

We account for goodwill in accordance with Financial Accounting Standards Board, or FASB, Accounting Standard Codification, or ASC, 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 2013, we have determined that the fair value of the goodwill and other indefinite-lived intangible assets are greater than their carrying values, thus no impairment charge was recorded. 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.

Volatility in the financial markets may negatively impact our ability to access 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 credit facility expires in January 2018 when the outstanding balance will be due. Any limitation of 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 could adversely impact us.

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 cease all of our non-banking activities and thus could have an adverse effect on our revenue and business.

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 impermissible activities. Failure to qualify for this exemption could 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.

17

WEX Bank’s bank regulatory status enables WEX Bank to issue certificates of deposit, accept money market deposits and NOW account deposits, and borrow on a federal funds rate basis from other banks. These funds are used to support our U.S. payment processing operations, which require the Company to make payments, as well as for our virtual card and paycard products. 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 Department of Financial Institutions and the FDIC. Continued licensing and federal deposit insurance are subject to ongoing satisfaction of compliance and safety and soundness requirements. WEX Bank must be adequately capitalized as defined in the banking regulations and satisfy a range of additional capital 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 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.

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 Department of Financial Institutions. 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 it, 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 statements. 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. 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.

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.

We are subject to restrictions 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 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 bar on engaging in

18

“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. Accordingly, WEX Bank may be unable to provide credit or engage in transactions with us, including transactions intended to help us service our indebtedness.

We may not be able to adequately protect 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 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 which was comprised 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.

Any security breach or inadvertent transmission of information about our customers or any violation of applicable privacy laws could expose us to liability in excess of any applicable insurance policies, litigation, regulatory scrutiny, and/or cause damage to our reputation.

Under the Gramm-Leach-Bliley Act (“GLBA”), 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.

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.

Any security breach or inadvertent transmission of information about our customers or any violation of 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.

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 all 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 services and capabilities our customers demand.

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

19

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 the same 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 (the “USA Patriot Act”) 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.

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 the Australian dollar, 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 effect during or at the end of each reporting period. Therefore, increases or decreases in the value of the U.S. dollar against other major currencies will affect our revenues, operating income and the value of balance sheet items denominated in foreign currencies. We cannot assure that fluctuations in foreign currency exchange rates, particularly fluctuations in the U.S. dollar against other currencies, will not materially affect 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”) and United Kingdom Bribery Act of 2010 (“UKBA”).

We are subject to both the FCPA and the United Kingdom Bribery Act, as we own subsidiaries organized under UK law, which serve as a holding company 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 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 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 or similar laws or regulations may increase as we expand globally and into countries with recognized corruption problems.

We may incur substantial losses due to fraudulent use of our card products.

Under certain circumstances, when we fund customer transactions, we bear the risk of substantial losses due to fraudulent use of our card products. We do not maintain any insurance to protect us against any such losses.

If we fail to maintain effective systems of internal control over financial reporting and disclosure controls and procedures, we may not be able to accurately report our financial results or prevent fraud, which could cause current and potential shareholders to lose confidence in our financial reporting, adversely affect the trading price of our securities or harm our operating results.

20

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. Any 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. As we complete acquisitions and expand our business operations both within the United States and internationally, we will need to maintain effective internal control over financial reporting and disclosure controls and procedures. If we are unable to adequately maintain our internal control over financial reporting, our external auditors will not be able to issue an unqualified 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, which may lead to deficiencies in the preparation of financial statements, 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 harm our business, affect our ability to raise capital and adversely affect the trading price of our securities.

Our ability to attract and retain qualified employees is critical to the success of our business 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.

Historical transactions with our former parent company may adversely affect our financial statements.

The accounting and tax treatment of historical transactions involving Avis Budget Group, Inc., or Avis (formerly Cendant Corporation), our former corporate parent, and our other former affiliates such as Realogy Corporation and Wyndham Worldwide Corporation, may be reviewed from time to time by external parties, which may include government regulatory organizations and tax authorities. The decision by one or more of these organizations to undertake a review is beyond our control. While management does not believe, nor has any knowledge of, any transaction that would be in error or otherwise adjusted, corrections to the financial statements of Avis, or its successor or its current or former affiliates, could adversely affect our financial statements due to the interrelated nature of how these past transactions impact our financial statements.

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% or more of a class of our voting stock would generally create a rebuttable presumption of control.

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.

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

21

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.

Our stockholder rights plan could prevent a stockholder from receiving a premium over the market price for shares of common stock from a potential acquirer.

Our board of directors approved a stockholder rights plan, which entitles our stockholders to acquire shares of our common stock at a price equal to 50 percent of the then current market value in limited circumstances when a third party acquires 15 percent or more of our outstanding common stock or announces its intent to commence a tender offer for at least 15 percent of our common stock, in each case, in a transaction that our board of directors does not approve. The existence of these rights would significantly increase the cost of acquiring control of our Company without the support of our board of directors because, under these limited circumstances, all of our stockholders, other than the person or group who caused the rights to become exercisable, would become entitled to purchase shares of our common stock at a discount. The existence of the rights plan could therefore deter potential acquirers and thereby reduce the likelihood that our stockholders will receive a premium for their common stock in an acquisition.

As of February 20, 2014, the closing price of our common stock was $90.76 per share, there were 38,890,626 shares of our common stock outstanding and there were five holders of record of our common stock. The actual number of stockholders is 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 a rolling 4-quarter basis, on the dividends it may pay under its revolving credit agreement.

Share Repurchases

We used $17.9 million during 2013 to repurchase our own common stock. We did not purchase shares of our common stock during the fourth quarter of 2013. The approximate dollar value of shares that were available to be purchased under the our share repurchase program was $150.0 million as of December 31, 2013.

On February 7, 2007, we announced a share repurchase program authorizing the purchase of up to $75 million of our common stock over a 24 month period. In July 2008, our Board of Directors approved an increase of $75 million to the share repurchase authorization, and then extended the share repurchase program through July 25, 2013. We were authorized to purchase, in total, up to $150 million of our common stock. This extended share repurchase program expired on July 25, 2013. On September 23, 2013, we announced a new share repurchase program authorizing the purchase of up to $150 million worth of our common stock from time to time until September 30, 2017. Share repurchases are to be made on the open market and can be commenced or suspended at any time. Through December 31, 2013, we have not used any of the authorized amount to acquire shares of our common stock under the new repurchase program.

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

2013 Highlights and Year in Review

WEX stands as a premier global payments solution provider in the fleet fuel market. Our opportunities for growth extend well beyond this market, and in particular to the online travel space. 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 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 continue to grow the business and create scale on a global basis. WEX is a leader in global virtual payments in the travel space.

Our Company was impacted by the following significant events and accomplishments in 2013:

• On November 8, 2013, we announced plans to acquire the assets of ExxonMobil’s European commercial fuel card (“Esso Card”) program through a majority owned subsidiary, WEX Europe Services Limited. The anticipated transaction is subject to completion of the employee information and consultation processes, and obtaining of competition authority approvals, as appropriate. Upon completion of the employee information and consultation process, WEX expects to enter into a definitive purchase and sale agreement related to the proposed acquisition with ExxonMobil. In addition, both parties plan to enter into a long term supply agreement to serve the current and future Esso Card customers and to grow the business. Under the terms of the proposed transaction, we will purchase ExxonMobil’s commercial fleet fuel card program which includes operations, funding, pricing, and sales and marketing in nine countries in Europe. In anticipation of an expected closing in late fourth quarter 2014 or first quarter 2015, we will make investments relating to the integration of operations and systems. It is anticipated that these investments will occur over a two year period, and are expected to impact 2014 earnings by $10 to $13 million after taxes. Upon completion of the deal, we estimate this portfolio will contribute approximately $35 million in annual revenue.

• On October 15, 2013, the Company's Brazilian subsidiary UNIK, which we own a 51 percent controlling interest in, acquired FastCred, a company specializing in the management of electronic payment of freight. In addition to expanding the customer base, the acquisition complements the range of UNIK products, facilitating UNIK's entry into the freight payment card industry in the Brazilian market.

• On January 30, 2013, we completed a $400 million offering in aggregate principal amount of our 4.750% senior notes due on February 1, 2023, at an issue price of 100.0 percent of the principal amount, plus accrued interest, from January 30, 2013, in a private placement. In connection with the $400 million offering, we entered into an Amended and Restated Credit Agreement (the “2013 Credit Agreement”), among the Company, as borrower, WEX Card Holdings Australia Pty Ltd (formerly Wright Express Card Holdings Australia Pty Ltd), a wholly-owned subsidiary of the Company, as specified designated borrower (“Card Holdings Australia”, and, together with the Company, the “Borrowers”), Bank of America, N.A., as administrative agent and letter of credit issuer (“Bank of America”), and the other lenders party thereto (the “Lenders”). The 2013 Credit Agreement provides for a five-year $300 million amortizing term loan facility, and a five-year $700 million secured revolving credit facility with a $150 million sub-limit for letters of credit.

26

• Total fleet transactions processed increased 10 percent from 2012 to 370.6 million in 2013. Payment processing transactions increased 12 percent from 2012 to 292.1 million in 2013, and transaction processing transactions increased 2 percent from 2012 to 78.5 million in 2013. These transactions include the operations from Fleet One, subsequent to the date of acquisition of October 4, 2012.

• Our payment solutions purchase card product grew to $13.1 billion in purchase volume for 2013, which is a 22 percent increase from 2012. This increase is primarily due to our single use account product used for online travel-related purchases.

• Domestic fuel prices averaged $3.67 per gallon during 2013, down from an average of $3.73 per gallon during 2012. Australian fuel prices decreased 5 percent in 2013 as compared to 2012, to US $5.39 per gallon.

Revenues

Payment processing revenue increased $31.8 million for 2013, as compared to 2012. This increase is primarily due to the organic growth from our domestic fleet business and the acquisition of Fleet One during the fourth quarter of 2012. Reducing the overall increase was a 2 percent decrease in the average domestic price per gallon of fuel, as compared to 2012.

Transaction processing revenue increased $2.5 million for 2013, as compared to 2012. This increase is primarily due to network fees at Fleet One, which was acquired during the fourth quarter of 2012.

Account servicing revenue increased $8.3 million for 2013, as compared to 2012. This increase is primarily due to the acquisition of Fleet One during the fourth quarter of 2012 as well as an increase in WEX Telematics units service revenue.

28

Our finance fees increased $9.5 million for 2013, as compared to 2012. With the acquisition of Fleet One during the fourth quarter of 2012, its factoring revenue has been included in finance fee revenue as well as the late fee revenue historically reported by the Company. The increase in finance fees is primarily due factoring revenue at Fleet One for 2013. Payments for customer receivables are due within thirty days or less. Late fee revenue, which is included in finance fees, is earned when a customer’s receivable balance becomes delinquent. The late fee is calculated using a stated late fee rate based on the outstanding balance. The absolute amount of such outstanding balances can be attributed to (i) changes in 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 the number of customers with overdue balances. The change in 2013 is primarily due to the addition of (i) factoring revenue and (ii) higher accounts receivable balances, as a result of higher transaction volumes, resulting in an increase of approximately $3.3 million over 2012.

Expenses

The following table compares selected expense line items within our Fleet Payment Solutions segment:

(in thousands)	2013		2012		Increase (decrease)
Expense
Salary and other personnel	$	137,669	$	106,552	29	%
Service fees	$	31,563	$	32,641	(3	)%
Provision for credit losses	$	19,726	$	20,190	(2	)%
Technology leasing and support	$	15,384	$	11,468	34	%
Depreciation, amortization and impairments	$	51,437	$	52,500	(2	)%

• Salary and other personnel expenses increased $31.1 million for 2013, as compared to 2012. The increase is primarily due to additional employees from ongoing operations and from our acquisition of Fleet One, at the beginning of the fourth quarter of 2012.

• Service fees decreased $1.1 million during 2013, as compared to 2012. The decrease is primarily due to higher acquisition related expenses in 2012. This decrease is partially offset by higher fees associated with an increase in the numbers of WEX Telematics units, as compared to 2012, as well as a full year of fees incurred at Fleet One.

• Provision for credit losses decreased $0.5 million for 2013, as compared to 2012. We use a roll rate methodology to calculate the amount necessary for our ending receivable reserve balance. This methodology takes into account 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 ensure further overall reserve adequacy. We generally measure our credit loss performance by calculating credit losses as a percentage of total fuel expenditures on payment processing transactions. Our credit losses as a percentage of customers spend decreased to 7.9 basis points as compared to 10.0 basis points for 2012. This decrease is primarily associated with lower net charge offs as compared to 2012.

• Technology leasing and support expenses increased $3.9 million for 2013, as compared to 2012. The increase is primarily the result of additional software maintenance costs associated with new license agreements.

• Depreciation, amortization and impairments expenses decreased $1.1 million for 2013, as compared to 2012. During 2012, we incurred an $8.9 million write-off of the internally developed software for our over-the-road product. The write-off was a consequence of our decision to utilize the software acquired with the acquisition of Fleet One as the processing platform for our over-the-road product. Offsetting this decrease was additional amortization associated with the intangible assets related to the acquisition of Fleet One, acquired at the beginning of the fourth quarter of 2012.

Financing interest expense is related to our credit agreements, as well as our 2007 credit facility and 2010 term loan. Interest expense for 2013 increased $19.0 million from 2012, due to higher interest rates on our financing debt associated with our $400 million 4.750% fixed rate notes outstanding issued on January 30, 2013, (the "Notes"). The proceeds of these Notes were primarily used to pay down borrowings under our 2011 Credit Agreement, which had a variable interest rate that was lower at the time of repayment. Financing interest expense in 2013 includes a $1 million write-off of deferred loan fees

29

associated with the extinguishment of debt. The 2012 financing interest expense includes approximately $0.7 million in unamortized loan costs that was expensed at the time the 2007 credit facility was replaced.

Our effective tax rate was 38.4 percent for 2013 and 49.5 percent for 2012. The decrease in the effective tax rate compared to the prior year is primarily due to the impact of changes in the Australian tax consolidation laws in 2012. During the second quarter of 2012, we recorded a charge of approximately $26.3 million due to the impact of this tax legislation enacted on June 29, 2012, in Australia.

Fuel price derivatives

We own fuel price sensitive derivative instruments that we purchase on a periodic basis to manage the impact of volatility in domestic fuel prices on our cash flows. Our derivative instruments do not qualify for hedge accounting. Accordingly, realized and unrealized gains and losses on our fuel price sensitive derivative instruments affect our net income. During 2013 we recorded a loss of $9.9 million, consisting of a realized loss of $4.2 million and an unrealized loss of $5.6 million. During 2012 we recorded a loss of $12.4 million, consisting of a realized loss of $10.7 million and an unrealized loss of $1.7 million. These losses are due to the overall increase in the price of fuel relative to our hedged fuel prices.

ESSO Card program

On November 8, 2013, the Company announced that it plans to acquire the assets of ExxonMobil’s European commercial fuel card program through a majority owned subsidiary, WEX Europe Services Limited. The anticipated Esso Card program transaction is expected to close in late fourth quarter 2014 or first quarter 2015. We will make investments relating to the integration of operations and systems. It is anticipated that these investments will occur over a two year period, and are expected to impact 2014 earnings by $10 to $13 million after taxes.

Key operating statistics
Payment processing revenue:
Payment solutions purchase card volume	$	13,057,666		$	10,688,775		22	%

Payment processing revenue increased approximately $32.1 million for 2013, as compared to 2012. The primary driver of the increase in payment processing revenue is the increase in our corporate purchase card volume, which grew by approximately 2.4 billion in 2013 compared to 2012. Additionally, we experienced an increase in the charge card net interchange rate of 5 basis points during 2013 as compared to 2012, primarily due to customer specific incentives from our network provider.

Transaction processing revenue decreased approximately $1.8 million for 2013, as compared to 2012, primarily due to lower transaction based fees from WEX Prepaid Cards Australia (formerly Wright Express Prepaid Cards Australia).

Account servicing revenue increased approximately $5.4 million for 2013, as compared to 2012. Approximately $3.7 million of this increase is due to the acquisition of UNIK during 2012. The remaining increase is primarily due to domestic growth in our payroll card product.

Other revenue decreased $2.3 million for 2013 as compared to 2012, primarily due to the decrease in the of cross-border fees from the prior year as we process these transaction with local accounts. As a result of this decrease, our associated service fees have also decreased.

On November 9, 2012, the U.S District Court granted preliminary approval to a settlement between retailer, payment networks and card issuers regarding merchant interchange settlement fees. Under the terms of this settlement the domestic interchange rate for MasterCard branded credit card transactions was reduced by 10 basis points for a period of 8 months, beginning on July 29, 2013. This resulted in a revenue reduction of approximately $3.6 million in the second half of 2013.

Depreciation, amortization and impairments	$	6,771	$	22,763	(70	)%
Technology leasing and support	$	8,833	$	7,070	25	%

• Salary and other personnel expenses increased $10.0 million for 2013, as compared to 2012. Approximately $7.7 million of the increase is due to additional payroll costs associated with the operations of UNIK and CorporatePay acquired during 2012. The remaining increase is due to additional staff and increased benefit expense.

• Service fees increased by $1.3 million for 2013, as compared to 2012. Service fees increased by approximately $3.6 million as compared to the prior year due to additional expense associated with the operations of UNIK and CorporatePay, acquired during 2013. The increase is offset due to lower cross border fees as compared to the prior year.

• Provision for credit losses decreased $1.9 million for 2013, as compared to 2012. The decrease is primarily due to a bankruptcy from one customer during 2012.

• Depreciation, amortization and impairment expenses decreased $16.0 million for 2013, as compared to 2012. This decrease is primarily due to the $16.2 million impairment of goodwill associated with WEX Prepaid Cards Australia in 2012. During the third quarter of 2012, the Company determined that pricing pressure in the prepaid giftcard product in Australia would result in lower future earnings than forecasted at the time of the purchase of WEX Prepaid Cards Australia.

• Technology leasing and support expenses increased $1.8 million for 2013, as compared to 2012. This increase is primarily related to the volume increase in our corporate purchase card products.

Our effective tax rate was 36.1 percent for 2013 and 76.1 percent for 2012. The decrease in the effective tax rate compared to the prior year is partially due to changes in Australian tax consolidation laws. During 2012, we recorded a charge of approximately $5.1 million due to impact of the tax legislation enacted on June 29, 2012, in Australia. In addition, we did not recognize a tax benefit associated the goodwill impairment expense recorded in 2012.

Revenues

Payment processing revenue increased $22.7 million for 2012, as compared to 2011. Approximately $8.7 million of this increase is due to an increase in the number of domestic payment processing transactions. In addition, the 3 percent increase in the average domestic price per gallon of fuel, as compared to 2011, contributed approximately $3.9 million to this increase. The remaining increase is primarily due to the operations of Fleet One, acquired in the beginning of the fourth quarter of 2012.

Account servicing revenue increased $6.3 million for 2012, as compared to 2011. The increase in number of vehicles serviced in 2012 as compared to 2011, resulted in additional revenue of approximately $2.3 million. Approximately $2.0 million of the increase is due to the monthly fees received from our WEX Telematics units, which have increased, as compared to 2011. The remaining increase is primarily due to the operations of Fleet One, acquired in the beginning of the fourth quarter of 2012.

Our finance fees increased $3.9 million for 2012, as compared to 2011. With the acquisitions of Fleet One during the fourth quarter of 2012, its factoring revenue has been included in finance fee revenue as well as the late fee revenue historically

33

reported by the Company. Factoring revenue at Fleet One for the fourth quarter of 2012 was approximately $1.4 million. The change in 2012 is primarily due the addition of (i) factoring revenue and (ii) higher accounts receivable balances, as a result of higher fuel prices and transaction volumes, resulting in an increase of approximately $2.0 million over 2011.

Depreciation, amortization and impairments	$	52,500	$	39,904	32	%

• Salary and other personnel expenses increased $12.7 million for 2012, as compared to 2011. Approximately $10.9 million of this increase is due to additional employees from ongoing operations and from our acquisition of Fleet One, at the beginning of the fourth quarter of 2012. The remaining increase is due to a decrease in capitalized payroll of approximately $2.6 million in 2012 as compared to 2011, resulting in higher salary expense.

• Service fees increased $10.7 million during 2012, as compared to 2011. The increase is primarily due to expenses related to the 2012 acquisitions. Additionally, service fees associated with the WEX Telematics product line increased $1.3 million for 2012, as compared to 2011.

• Provision for credit losses decreased $6.4 million for 2012, as compared to 2011. Our credit losses as a percentage of customers spend decreased to 10.0 basis points as compared to 14.9 basis points for 2011. This decrease is primarily associated with lower charge offs as compared to 2011.

• Depreciation, amortization and impairment expenses increased $12.6 million for 2012, as compared to 2011. We incurred an $8.9 million write-off of the internally developed software for our over-the-road product during 2012. The write-off was a consequence of our decision to utilize the software acquired with the acquisition of Fleet One, during the fourth quarter of 2012, as the processing platform for our over-the-road product. Approximately $2.1 million of this increase is due to additional amortization associated with the intangible assets related to the acquisition of Fleet One, acquired at the beginning of the fourth quarter of 2012.

Financing interest expense is related to our 2011 Credit Agreement as well as our 2007 credit facility and 2010 term loan. Interest expense for 2012 decreased $1.2 million from 2011, due to lower interest rates on our financing debt, including the impacts of the interest rate swap that expired in March 2012. Finance interest expense in 2011 also includes approximately $0.7 million in unamortized loan costs that were expensed at the time the 2007 credit facility was replaced.

Our effective tax rate was 49.5 percent for 2012 and 35.9 percent for 2011. The increase in the effective tax rate compared to the prior year is primarily due to changes in Australian tax consolidation laws. During the second quarter of 2012, we recorded a charge of approximately $26.3 million due to the impact of this tax legislation enacted on June 29, 2012, in Australia.

Fuel price derivatives

During 2012, we recorded a loss of $12.4 million, consisting of a realized loss of $10.7 million and an unrealized loss of $1.7 million. During 2011, we recorded a loss of $11.8 million, consisting of a realized loss of $22.7 million and an unrealized gain of $10.9 million. The increase in losses is due to the overall increase in the price of fuel relative to our hedged fuel prices.

Payment processing revenue increased approximately $23.9 million for 2012, as compared to 2011. Approximately $6.9 million of this increase is due to the acquisition of UNIK and Corporate Pay during 2012. The remaining increase is primarily due to additional business derived from our virtual card product, partially offset with a reduction in the interchange rate in 2012, as compared to 2011 due to contract mix, increased foreign spend, which generally has a lower interchange rate than domestic transactions, and a reduction in customer specific incentives received. Our corporate purchase card volume grew by over $2.53 billion in 2012 compared to 2011.

Transaction processing revenue decreased approximately $0.8 million for 2012, as compared to 2011, primarily due to lower transaction based fees from WEX Prepaid Cards Australia.

Account servicing revenue increased approximately $3.1 million for 2012, as compared to 2011. Approximately $1.1 million of this increase is due to the acquisition of UNIK and CorporatePay during 2012. The remaining increase is due to primarily due to the inclusion of a full year of operation of rapid! PayCard, which was acquired at the end of the first quarter of 2011.

Other revenue increased $8.4 million for 2012 as compared to 2011, primarily due to the increase in the volume of cross-border fees over the prior year. This increase is partially offset by an increase in associated service fees expense.

• Depreciation, amortization and impairment expenses increased $17.3 million for 2012, as compared to 2011. This increase is primarily due to the September 30, 2012, $16.2 million impairment of goodwill associated with WEX Prepaid Cards Australia. During the third quarter of 2012, the Company determined that pricing pressure in the prepaid giftcard product in Australia would result in lower future earnings than forecasted at the time of the purchase of WEX Prepaid Card Australia.

• Technology leasing and support expenses increased $2.1 million for 2012, as compared to 2011. This increase is primarily related to the volume increase in our corporate purchase card products.

Our effective tax rate was 76.1 percent for 2012 and 36.3 percent for 2011. The increase in the effective tax rate compared to the prior year is primarily due to changes in Australian tax consolidation laws. During 2012, we recorded a charge of approximately $5.1 million due to impact of the tax legislation enacted on June 29, 2012, in Australia.

LIQUIDITY, CAPITAL RESOURCES AND CASH FLOWS

We believe that our cash generating capability and financial condition, together with our revolving credit agreement, term loan and $400 million notes outstanding, as well as other available methods of financing (including deposit and borrowed federal funds), are adequate to meet our operating, investing and financing needs. As part of our overall financial structure, our industrial bank subsidiary, WEX Bank, utilizes brokered deposits, negotiable order of withdrawal (“NOW”) deposits and borrowed federal funds to finance our domestic accounts receivable.

The table below summarizes our cash activities: 

	Year ended December 31,
(in thousands)	2013			2012			2011
Net cash provided by operating activities	$	39,551		$	71,811		$	51,168
Net cash used for investing activities	(51,342		)	(429,824		)	(40,504		)
Net cash provided by (used for) financing activities	179,242			529,564			(2,583		)

2013 Highlights

• During 2013, our increase in accounts receivable, net of the account receivable balances acquired with our acquisitions, is funded by operating activities as well as a $150 million overall increase in borrowed federal funds and deposits. Accounts receivable increased in 2013 over 2012 as a result of increased customer spend levels.

• On October 15, 2013, the Company's Brazilian subsidiary UNIK, in which we own a 51 percent controlling interest, acquired FastCred, a provider of fleet cards to the heavy truck or over-the-road segment of the fleet market in Brazil, for $12.3 million. The acquisition was funded through our term loan.

• On September 23, 2013, our Board of Directors authorized a new share repurchase program under which up to $150 million worth of our common stock may be repurchased from time to time until September 30, 2017, through open market purchases. We used $17.9 million during 2013 to repurchase our own common stock.

• During 2013, we had $39.5 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 abroad. During 2013, we also capitalized approximately $13 million related to the consolidation of our data centers. We expect total capital expenditures for 2014 to be approximately $40 to $45 million. Our capital spending is financed primarily through internally generated funds.

2012 Highlights

• During 2012, our increase in accounts receivable, net of the account receivable balances acquired with our acquisitions, is funded by operating activities as well as a $235 million overall increase in borrowed federal funds and deposits. The excess of NOW deposits is a result of the influx of capital associated with the Company's program with Higher One, Inc., a technology and payment processing company, through which the Company to a portion of Higher One Inc.'s customers. Accounts receivable increased in 2012 over 2011 as a result of increased customer spend levels, primarily due to higher fuel prices.

• On May 11, 2012, we acquired all of the stock of CorporatePay, a provider of corporate prepaid solutions to the travel industry in the United Kingdom for $27.8 million, net of cash acquired. The acquisition was funded through our revolving credit facility and term loan.

2011 Highlights

• During 2011, our increase in accounts receivable, net of the account receivable balance acquired with the acquisition of rapid! PayCard, is funded by operating activities as well as a $111 million overall increase in borrowed federal funds and brokered deposits. Accounts receivable increased in 2011 over 2010 as a result of increased customer spend levels, due to higher fuel prices.

• During 2011, we entered into a new credit facility and paid down $112.0 million of our financing debt.

• On March 31, 2011, we completed the acquisition of the assets of rapid! PayCard for $18.1 million, which included a $10 million projected earn-out payment at the end of the first quarter of 2012. The acquisition was funded through our revolving credit facility and term loan.

• During 2011, we had $25.1 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 abroad.

Liquidity

General

In general, our trade receivables provide for payment terms of 30 days or less. We do not extend revolving credit to our customers with respect to these receivables. Receivables not paid within the terms of the customer agreement are generally subject to finance fees based upon the outstanding customer receivable balance. At December 31, 2013, approximately 95 percent of the outstanding balance of $1,722 million of total trade accounts receivable was current and approximately 99 percent of the outstanding balance of total trade accounts receivable was less than 60 days past due. The outstanding balance is made up of receivables from a wide range of industries. No customer makes up more than 4 percent of the outstanding receivables at December 31, 2013.

Our short-term cash requirements consist primarily of payments to major oil companies for purchases made by our fleet customers, payments to merchants for other payment solutions, payments on maturing and withdrawals of brokered deposits and borrowed federal funds, interest payments on our credit facility, cash payments for derivative instruments and other operating expenses. WEX Bank is responsible for the majority of domestic payments to major oil companies, merchants, and payments on maturing and withdrawals of brokered deposits and borrowed federal funds. 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.

2013 Credit Agreement

On January 18, 2013, the Company entered into an Amended and Restated Credit Agreement (the “2013 Credit Agreement”), among the Company, as borrower, WEX Card Holdings Australia Pty Ltd, a wholly-owned subsidiary of the Company, as specified designated borrower, Bank of America, N.A., as administrative agent and letter of credit issuer, and the other lenders party thereto. The 2013 Credit Agreement is secured by pledges of the stock of our foreign subsidiaries.

The 2013 Credit Agreement provides for a five-year $300 million amortizing term loan facility, and a five-year $700 million secured revolving credit facility with a $150 million sub-limit for letters of credit. The 2013 Credit Agreement replaced the 2011 Credit Agreement, dated as of May 23, 2011. Subject to certain conditions, including obtaining relevant commitments, the Company has the option to increase the facility by up to an additional $100 million. As of December 31, 2013, we also had approximately $11.9 million in letters of credit outstanding. At December 31, 2013, we had $285 million of borrowed funds, and $688 million available, under the 2013 Credit Agreement, subject to the covenants as described below. Proceeds from the

38

2013 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.

Amounts outstanding under the 2013 Credit Agreement bear interest at a rate equal to, at the Company’s option, (a) the Eurocurrency Rate, as defined, plus a margin of 1.25 percent to 2.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the highest of (i) the Federal Funds Rate plus 0.50 percent (ii) the prime rate announced by the lead lender, and (iii) the Eurocurrency Rate plus 1.00 percent, in each case plus a margin of 0.25 percent to 1.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA. In addition, the Company has agreed to pay a quarterly commitment fee at a rate per annum ranging from 0.20 percent to 0.40 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA of the daily unused portion of the credit facility. Any outstanding loans under the 2013 Credit Agreement mature on January of 2018, unless extended pursuant to the terms of the 2013 Credit Agreement.

Our 2013 Credit Agreement contains financial covenants requiring us to maintain certain financial ratios. Specifically, it limits us to a maximum consolidated leverage ratio of 3.25 to 1.00 at the end of each fiscal quarter until the maturity date. The 2013 Credit Agreement also requires us to maintain a minimum consolidated interest coverage ratio of 3.00 to 1.00 at the end of each fiscal quarter until the maturity date.

In addition to the financial covenants, the 2013 Credit Agreement contains various customary restrictive covenants that limited our ability to pay dividends, sell or transfer all or substantially all of our property or assets, incur more indebtedness or make guarantees, grant or incur liens on our assets, make investments, loans, advances or acquisitions, engage in mergers, consolidations, liquidations or dissolutions and enter into sales or leasebacks. We were in compliance with all material covenants and restrictions at December 31, 2013.

At December 31, 2013, we did not have any interest rate swap arrangements in place, however we regularly review our projected borrowings under our credit facility and the current interest rate environment to determine if additional swaps should be executed.

$400 million 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.

2011 Credit Agreement

On May 23, 2011, we entered into a Credit Agreement (the “2011 Credit Agreement”), by and among us and certain of our subsidiaries, as borrowers, and WEX Card Holdings Australia Pty Ltd, as specified designated borrower, with a lending syndicate. The 2011 Credit Agreement was secured by pledges of the stock of our foreign subsidiaries. The 2011 Credit Agreement provided for a five-year $200 million amortizing term loan facility and a five-year $700 million revolving credit facility with a $100 million sub-limit for letters of credit. Term loan payments in the amount of $2.5 million were due beginning on June 30, 2011, and thereafter on the last day of each September, December, March and June thereafter, through and including March 31, 2016, and on the maturity date for the term agreement, May 23, 2016, the remaining outstanding principal amount of $150 million was due.

Proceeds from the 2011 Credit Agreement were used to repay our indebtedness under the 2007 credit facility with a lending syndicate, and indebtedness under the 2010 term loan facility with a bank. The 2011 Credit Agreement funding was available for working capital purposes, acquisitions, payment of dividends and other restricted payments, refinancing of indebtedness, and other general corporate purposes.

Amounts outstanding under the 2011 Credit Agreement bore interest at a rate equal to, at our option, (a) the Eurocurrency Rate, as defined, plus a margin of 1.25 percent to 2.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the highest of (i) the Federal Funds Rate plus 0.50 percent, (ii) the prime rate announced by the lead lender, or (iii) the Eurocurrency Rate plus 1.00 percent, in each case plus a margin of 0.25 percent to 1.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA. In addition, we agreed to pay a quarterly commitment fee at a rate per annum ranging from 0.20 percent to 0.40 percent of the daily unused portion of the credit facility. The 2011 Credit Agreement also contained financial covenants and customary restrictive covenant that were material similar to the 2013 Credit Agreement.

39

The Company maintained interest rate swap arrangements in conjunction with the 2011 Credit Agreement that effectively converted $150 million of variable rate borrowing to fixed rate borrowing at a rate of approximately 0.56 percent that expired in March of 2012.

Deposits and borrowed federal funds

WEX Bank issued certificates of deposit in various maturities ranging between one month and two years and with fixed interest rates ranging from 0.30 percent to 0.80 percent as of December 31, 2013, as compared to fixed interest rates ranging from 0.26 percent to 1.15 percent as of December 31, 2012, and 0.25 percent to 1.60 percent as of December 31, 2011. WEX Bank also issues interest-bearing money market deposits with variable interest rates ranging from 0.15 percent to 0.35 percent as of December 31, 2013, as compared to variable interest rates ranging from 0.35 percent to 0.41 percent as of December 31, 2012, and 0.60 percent to 0.73 percent as of December 31, 2011. As of December 31, 2013, we had approximately $222.5 million of brokered deposits outstanding at a weighted average interest rate of 0.25 percent, compared to $613.1 million of brokered deposits at a weighted average interest rate of 0.53 percent as of December 31, 2012, and approximately $683.3 million of brokered deposits outstanding at a weighted average interest rate of 0.68 percent as of December 31, 2011.

WEX Bank may issue brokered deposits without limitation on the balance outstanding. However, WEX Bank must maintain minimum financial ratios, which include risk-based asset and capital requirements, as prescribed by the FDIC. As of December 31, 2013, 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.

Beginning during the second quarter of 2012, we received non-interest bearing NOW account deposits. As of December 31, 2013, we had $276.4 million of non-interest bearing NOW account deposits. These deposits were in excess of our operating cash requirements to fund account receivables, which resulted in a larger than typical cash balance on our consolidated balance sheet for the current period. We anticipate this balance to decline based on historical patterns of the non-interest bearing NOW account deposits and scheduled maturities of our deposits. Deposits are subject to regulatory capital requirements.

We also carry non-interest bearing deposits that are required for certain customers as collateral for their credit accounts. We had $18.6 million of these deposits on hand at December 31, 2013, $16.2 million at December 31, 2012, and $10.4 million at December 31, 2011.

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 $125.0 million as of December 31, 2013, and $140.0 million as of December 31, 2012 and 2011, respectively, with no outstanding balance as of December 31, 2013.

Other Liquidity Matters

We discuss our hedging strategies relative to commodity and interest rate risk in Item 7A below. Our fuel price derivatives are entered into to mitigate the volatility that domestic fuel prices introduce to our revenue streams. The effect of these derivatives is to restrict a portion of our fuel price exposure to a collar range set in the previous year. As a result, at December 31, 2013, we have a liability related to these derivatives of approximately $7.4 million. During the course of the year we paid $4.2 million from the net settlement of expiring derivative contracts. Our long-term cash requirements, apart from amounts owing on our 2013 Credit Agreement, consist primarily of amounts due to Wyndham Worldwide Corporation (see Note 13 - Tax Receivable Agreement, in Part II, Item 8) as part of our tax receivable agreement.

Undistributed earnings of certain foreign subsidiaries of the Company amounted to $4.7 million at December 31, 2013, and $1.8 million at December 31, 2012. These earnings are considered to be indefinitely reinvested, and accordingly, no U.S. federal and state income taxes have been provided thereon. If we were to distribute such earnings in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. The Company’s primary tax jurisdictions are the United States and Australia.

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, or the degree to which we will be able to manage the impact of currency exchange rate changes.

As of December 31, 2013, we have approximately $38.6 million in cash located in our foreign entities, outside of the United States.

40

We currently have authorization from our Board to purchase up to $150 million of our common stock until September 30, 2017. Through December 31, 2013, we have not used any of the authorized amount to acquire shares of our common stock. The program will be funded either through our future cash flows or through borrowings on our 2013 Credit Agreement. Share repurchases will be 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, will determine the timing and number of shares repurchased.

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

Off-balance Sheet Arrangements

We have the following off-balance sheet arrangements as of December 31, 2013:

• 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.

• Extension of credit to customers.  We have entered into commitments to extend credit in the ordinary course of business. We had approximately $5.65 billion of commitments to extend credit at December 31, 2013, as part of established customer agreements. These amounts may increase or decrease during 2013 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 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.  We are required to post collateral primarily related to facility lease agreements and virtual card and fuel payment processing activity at our foreign subsidiaries. As of December 31, 2013, we have posted a $11.9 million letter of credit as collateral.

Uncertain tax liabilities - At this time, the Company is unable to make a reasonably reliable estimate of the timing of payments in individual years in connection with uncertain tax liabilities; therefore, such amounts are not included in the above contractual obligation table.

Letters of credit - As of December 31, 2013, we had $11.9 million outstanding in undrawn 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.

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.

Reserve for Credit Losses

Description	Assumptions/Approach Used	Effect if Actual Results Differ from Assumptions
The reserve for losses relating to accounts receivable represents management’s estimate of the losses inherent in the Company’s outstanding portfolio of receivables. 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.	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, 2013, we have estimated a reserve for credit losses which is 0.60 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 $8.6 million. For the past three years, our reserve for credit losses in an annual period has not been in excess of 1.0 percent of the total receivable.

43

Business Combinations, Acquired Intangible Assets and Goodwill

Description	Assumptions/Approach Used	Effect if Actual Results Differ from Assumptions
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.   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.	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. 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 two 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 by 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, 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.	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 relatively 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, 2013, the Company had an aggregate of approximately $1,027 million on its consolidated balance sheet related to goodwill and intangible assets of acquired entities. Our analysis indicates that the calculated fair value of our reporting units support their carrying values as of December 31, 2013.

44

Valuation of Derivatives

Description	Assumptions/Approach Used	Effect if Actual Results Differ from Assumptions
The Company has entered into several financial arrangements that are considered to be derivative transactions. In the case that the Company has entered into fuel price derivatives, no hedging relationship has been designated. Accordingly, when the derivatives are marked to their market value, the related gains or losses are recognized currently in earnings.	None of the derivatives that exist have readily determinable fair market values. Management determines fair value through alternative valuation approaches, primarily modeling that considers the value of the underlying index or commodity (where appropriate), over-the-counter market quotations, time value, volatility factors and counterparty credit risk. On a periodic basis, management reviews the statements provided by the counterparty to ensure the fair market values are reasonable when compared to the one it derived.	As of December 31, 2013, the Company had established that the net fair value of the derivatives was a liability of $7.4 million. Changes in fuel prices, interest rates and other variables have a significant impact on the value of the derivatives. Should either (i) the variables underlying pricing methodologies; (ii) the creditworthiness of the counterparty or (iii) the methodologies themselves substantially change, our results of operations could significantly change.

Changes to Accounting Policies

In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2013-11 Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11"). The amendments in ASU 2013-11 require entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss ("NOL") carryforward, a similar tax loss, or a tax credit carryforward except when the following exist: (i) an NOL carryforward, a similar tax loss, or a tax credit carryforward is not available as of the reporting date under the governing tax law to settle taxes that would result from the disallowance of the tax position, and (ii) the entity does not intend to use the deferred tax asset for this purpose (provided the tax law permits a choice). If any of these conditions exist, entities should present an unrecognized tax benefit in the financial statements as a liability and should not net the unrecognized tax benefit with a deferred tax asset. ASU 2013-11 is effective for interim and annual periods beginning after December 15, 2013. We do not believe that the adoption of ASU 2013-11 will have a material impact on its results of operations when adopted in 2014.

In February 2013, the FASB issued Accounting Standards Update No. 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This guidance is intended to provide disclosure on items reclassified out of accumulated other comprehensive income either in the notes or parenthetically on the face of the income statement. The required disclosure is in Note 18, Accumulated Other Comprehensive Income.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company has entered into market risk sensitive instruments for purposes other than trading. The discussion below highlights quantitative and qualitative matters related to these instruments. All of the potential changes noted below are based on sensitivity analyses performed on our financial position at December 31, 2013. Actual results may differ materially.

Interest Rate Risk

At December 31, 2013, we had borrowings of $285 million under our 2013 Credit Agreement that bore interest at variable rates. We periodically review our projected borrowing under our 2013 Credit Agreement and the current interest rate environment in order to ascertain whether interest rate swaps should be entered into to either increase our coverage of our overall borrowings.

At December 31, 2013, WEX Bank had deposits (includes certificates of deposits, interest bearing money market deposits and borrowed federal funds) outstanding of $1,071 million. 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.

The following table presents the impact of changes in LIBOR on interest expense on our revolving credit facility and term loan for 2013 on the principal outstanding under the credit facility, as well as the impact of changes in interest rates on certificates of deposits, interest bearing money market deposits and borrowed federal funds:

(in thousands)	Impact(a)
Projected annual financing interest expense on credit agreement borrowings (assumes one-month LIBOR plus 175 basis points equal to 1.917%)	$	5,463
Increase of:
1.00%	$	2,850
2.00%	$	5,700
Projected annual operating interest expense on WEX Bank deposits (certificates of deposits at 0.53% and interest bearing money market deposits at 0.25%)	$	3,585
Increase of:
1.00%	$	7,939
2.00%	$	15,879

^(a)    Changes to interest expense presented in this table are based on interest payments, outstanding balance and rate as of December 31, 2013.

At December 31, 2013, WEX Bank had negotiable order of withdrawal account deposits outstanding of $276 million.

(in thousands)	Impact(b)
Projected annual interest expense (based on the federal fund rate) on NOW account deposits using federal funds rate of 0.25%	$	—
Increase of:
1.00%	$	—
2.00%	$	346

^(b)    Changes to interest expense presented in this table are based on the outstanding balance and rate as of December 31, 2013.

Foreign Currency Risk

Growth in our international operations will incrementally increase our exposure to foreign currency fluctuations as well as other risks typical of international operations, including, but not limited to, differing economic conditions, changes in political climate, differing tax structures and other regulations and restrictions. Foreign exchange rate fluctuations may adversely impact our consolidated results of operations as exchange rate fluctuations on transactions denominated in currencies other than our functional currencies result in gains and losses that are reflected in our consolidated statements of operations. To the extent the U.S. dollar weakens against foreign currencies, the translation of these foreign currency-denominated transactions will result in increased net revenues and operating expenses. Conversely, our net revenues and operating expenses will decrease when the U.S. dollar strengthens against foreign currencies.

Commodity Price Risk

46

As discussed in the “Fuel Price Derivatives” section of Item 1, we use derivative instruments to manage the impact of volatility in North American fuel prices. We have entered into put and call option contracts (“Options”) based on the wholesale price of unleaded gasoline and retail price of diesel fuel, which settle on a monthly basis through the second quarter of 2015. The Options are intended to lock in a range of prices during any given quarter on a portion of our forecasted earnings subject to fuel price variations. Our fuel price risk management program is designed to purchase derivative instruments to manage our fuel price-related earnings exposure.

The following table presents information about the Options:

					December 31, 2013

Total fuel price derivative instruments – diesel					18,015	$	(2,142	)
Total fuel price derivative instruments					55,880	$	(7,358	)

^(a)    The settlement of the Options is based upon the New York Mercantile Exchange’s New York Harbor Reformulated Gasoline Blendstock for Oxgenate Blending and the U.S. Department of Energy’s weekly retail on-highway diesel fuel price for the month.

^(b)    The Options settle on a monthly basis.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of WEX Inc.

South Portland, Maine

We have audited the accompanying consolidated balance sheets of WEX Inc. and subsidiaries (the “Company”) as of December 31, 2013 and 2012, and 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, 2013. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of WEX Inc. and subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013, 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), the Company’s internal control over financial reporting as of December 31, 2013, based on the criteria established in Internal Control-Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2014 expressed an unqualified opinion on the Company’s internal control over financial reporting.

Business Description

WEX Inc. (“Company”) is a provider of corporate card payment solutions. The Company provides products and services that meet the needs of businesses in various geographic regions including North and South America, Asia Pacific and Europe. The Company’s Fleet Payment Solutions and Other Payment Solutions segments provide its customers with security and control for complex payments across a wide spectrum of business sectors. The Company markets its products and services directly, as well as through strategic relationships which include major oil companies, fuel retailers and vehicle maintenance providers.

Basis of Presentation

The accompanying consolidated financial statements of WEX Inc. for the years ended December 31, 2013, 2012 and 2011, include the accounts of WEX Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

The Company adjusted the consolidated balance sheet amounts as of December 31, 2012, to account for the measurement period adjustments related to the CorporatePay, UNIK and Fleet One purchase price allocations discussed in Note 3, Business Acquisitions, and Other Intangible Asset Acquisitions below. The Company adjusted the statement of stockholders' equity amounts as of December 31, 2010, and for the years ended December 31, 2011 and 2012, to present treasury shares purchased and deferred stock units vested. The Company adjusted the statements of cash flow for the years ended December 31, 2011 and 2012, to combine acquisitions and investments into one single line item presentation.

The presentation of the Company’s consolidated balance sheet as of December 31, 2012 has been corrected for an immaterial error in the classification of foreign deferred tax liabilities. As of December 31, 2012, the foreign jurisdiction deferred tax liability balance was erroneously netted with the domestic deferred tax asset balance and presented on the consolidated balance sheet as a deferred tax asset. This correction of the error resulted in an increase in deferred tax assets and total assets of $18,407 and a corresponding increase in deferred tax liabilities, total liabilities, and total liabilities and stockholders’ equity of $18,407. The result of this correction did not impact the Company’s consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for any period presented.

Use of Estimates and Assumptions

The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. 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 market value. Cash equivalents include federal funds sold, which are unsecured short-term investments entered into with financial institutions.

Accounts Receivable and Reserve for Credit Losses

Accounts receivable balances are 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, 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.

Available-for-sale Securities

55

WEX INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(in thousands, except per share data)

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 sheet in accumulated other comprehensive income (loss). Realized gains and losses and declines in fair value determined to be other-than-temporary on available-for-sale securities are included in non-operating revenues and 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 revenues. 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

The Company uses derivative instruments as part of its overall strategy to manage its exposure to fluctuations in fuel prices and to reduce the impact of interest rate volatility. All derivatives are recorded at fair value on the consolidated balance sheet.

The Company’s fuel price derivative instruments do not qualify for hedge accounting treatment; therefore, gains or losses related to fuel price derivative instruments, both realized and unrealized, are recognized in earnings. These instruments are presented on the consolidated balance sheet as fuel price derivatives, at fair value. For the purposes of cash flow presentation, realized gains or losses are included in operating cash flows, as they are intended to hedge operating cash flows.

In prior years, the Company used interest rate derivatives designated as cash flow hedges and, accordingly, the change in fair value associated with the effective portion of these derivative instruments that qualified for hedge accounting treatment was recorded as a component of other comprehensive income (loss) and the ineffective portion, if any, was reported in earnings. Amounts included in other comprehensive income (loss) were reclassified into earnings in the same period during which the hedged item affected earnings. These instruments were presented as either other assets or accrued expenses on the consolidated balance sheet.

The Company assessed the hedge effectiveness of the interest rate swaps in accordance with the requirements outlined in the accounting standards. For these hedges, management documented, both at inception and over the life of the hedge, at least quarterly, its analysis of actual and expected hedge effectiveness. For those hedging relationships in which the critical terms of the entire debt instrument and the derivative were identical, and the creditworthiness of the counterparty to the hedging instrument remained sound, there was no hedge ineffectiveness as long as those conditions continue to be met. As of December 31, 2013, the Company does not have any interest rate swaps outstanding.

Property and Equipment

Property and equipment are stated at cost less 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. Leasehold improvements are primarily depreciated using the straight-line method over the lesser of the useful life of the asset or over the remaining lease term.

Below is the estimated useful lives for assets placed in service during 2013 and beyond:

	Estimated Useful Lives
Furniture, fixtures and equipment	3 to 5 years
Computer software	18 months to 7 years
Leasehold improvements	up to 5 years

Capitalized Software

The Company develops software that is used in providing 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. Software development costs are capitalized beginning when technological feasibility of the software has been established. Costs incurred prior to establishing technological feasibility are expensed as incurred. Technological feasibility is established when the Company has completed all planning, designing, coding and testing activities that are necessary to determine that the software can be produced to meet its design specifications, including functions, features and technical performance requirements. Capitalization of costs ceases when the software is ready for its intended use. 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 expensed for amortization of internal-use computer software	18,830		20,694		18,690

Goodwill and Other Intangible Assets

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 would record 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.

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 a variety of methodologies to estimate fair value, but primarily relies on discounted cash flow analyses. 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 fair value. Impairment charges are recorded in depreciation, amortization and impairment expense on the consolidated statements of income. The Company's annual goodwill and intangible asset impairment tests performed as of October 1, 2013 did not identify any impairment. The Company’s annual goodwill and intangible assets impairment tests, performed as of October 1, 2012, identified an impairment of $1,337 of goodwill associated with the acquisition of Financial Automation Limited, acquired in August of 2008. On September 30, 2012, the Company impaired $16,171 of goodwill associated with Wright Express Australia Prepaid.

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. 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. 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 Long-lived 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. If indicators exist, 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 (normally measured by the expected present value technique) is required. The Company recognized an expense of $8,903 during the year ended December 31, 2012. This expense is a consequence of the Company’s decision to utilize the software acquired with the acquisition of Fleet One, during the fourth quarter of 2012, as the processing platform for its over-the-road product. The Company also recognized approximately $600 in impairments and disposals of various other long-lived assets during the year ended December 31, 2012, some of which were related to the Fleet One acquisition. The Company did not recognize any significant impairment expense on the Company’s long-lived assets during the years ended December 31, 2013 and 2011. Write-offs due to the acquisition of Fleet One were recorded in depreciation, amortization and impairments in the consolidated statements of income. Disposals over the ordinary course of business are recorded in occupancy and equipment in the consolidated statements of income.

Other Assets

57

WEX INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(in thousands, except per share data)

The Company has an investment in the stock of the Federal Home Loan Bank totaling $1,479 for the year ended December 31, 2013, $1,534 for the year ended December 31, 2012 and $1,562 for the year ended December 31, 2011. The investment is carried at cost and not considered a readily marketable security. This investment is included in other assets on the consolidated balance sheets. As of December 31, 2013, the Company has concluded that the investment is not impaired.

Fair Value of Financial Instruments

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, borrowed federal funds and credit agreement borrowings approximate their respective fair values as the interest rates on these financial instruments are variable. All other financial instruments are reflected at fair value on the consolidated balance sheet.

Revenue Recognition

The majority of the Company’s revenues are comprised of transaction-based fees, which generally are 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 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.

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

Payment Processing Revenue.    Revenue consists of transaction fees assessed to major oil companies, fuel retailers and vehicle maintenance providers. 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. 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.

Interchange income is earned by the Company’s corporate purchase card and payroll card products and is included in payment processing revenue. 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 payment processing revenue, the Company is generally responsible for the collection of the total transaction amount 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 wholesale 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.

Transaction Processing Revenue.    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.

Account Servicing Revenue.    Revenue is primarily comprised of monthly fees based on vehicles serviced. These fees are primarily in return for providing monthly vehicle data reports. Account servicing revenue is recognized monthly, as the Company fulfills its contractual service obligations. The Company also recognizes service fees related to rapid! PayCard services for card fees charged to the cardholder.

(in thousands, except per share data)

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 the entire balance outstanding from the customer. On occasion, these fees are waived. The Company’s established reserve for such waived amounts is estimated and offset against the late fee revenue recognized. These waived fees amounted to $4,557 in 2013 and $3,905 in 2012. The Company’s subsidiary, Fleet One, 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 interest earned on the Company’s foreign paycard product.

Other.    The Company assesses fees for providing ancillary services, such as information products and services, 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. 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. In addition, the Company sells assorted equipment to its Pacific Pride franchisees. 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.

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.

Stock-Based Compensation

The Company recognizes the fair value of all stock-based payments to employees in its financial statements. The Company measures stock-based compensation expense at the grant date, based on the estimated fair value of the award and uses the straight-line method of attribution, net of estimated forfeitures, for expensing awards over the employee requisite service period. The Company estimates the fair value of stock option awards using a Black-Scholes-Merton valuation model. 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 is recorded in salary and other personnel expense.

Advertising Costs

Advertising and marketing costs are expensed in the period the advertising activity occurs.

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 realizability of deferred tax assets must also be assessed. 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 must be established for deferred tax assets which are not believed to more likely than not be realized in the future. Deferred taxes are not provided for the undistributed earnings of the Company’s foreign subsidiaries that are considered to be indefinitely reinvested outside of the United States.

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 Common Share

WEX INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(in thousands, except per share data)

When diluted earnings per common share is calculated, weighted-average outstanding shares are adjusted for the dilutive effect of shares issuable upon the assumed conversion of the Company’s common stock equivalents, which consist of outstanding stock options and unvested restricted stock units. Holders of unvested restricted stock units are not entitled to participate in dividends, should they be declared.

Income available for common stockholders used to calculate earnings per share is as follows:

	Year ended December 31,
	2013		2012		2011
Net earnings attributable and available for common stockholders –Basic and Diluted	$	149,208	$	96,922	$	133,622

Weighted average common shares outstanding used to calculate earnings per share are as follows:

	Year ended December 31,
	2013	2012	2011
Weighted average common shares outstanding – Basic	38,946	38,840	38,686
Unvested restricted stock units	117	138	128
Stock options	40	114	184
Weighted average common shares outstanding – Diluted	39,103	39,092	38,998

Foreign Currency Movement

The financial statements of the Company’s foreign subsidiaries, whose functional currencies are other than the U.S. dollar, are translated to U.S. dollars. Assets and liabilities are translated at the year-end spot exchange rate, revenue and expenses at average exchange rates and equity transactions at historical exchange rates. Exchange differences arising on translation are recorded as a component of accumulated other comprehensive income (loss).

Realized and unrealized gains and losses on foreign currency transactions are recorded directly in the consolidated statements of income except when such gains or losses result from intercompany transactions where repayment is not anticipated for the foreseeable future. In these situations, the gains or losses are deferred and included as a component of accumulated other comprehensive income (loss).

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) includes unrealized gains and losses on available-for-sale securities, the changes in fair values of derivative instruments designated as hedges of future cash flows related to interest rate variability 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.

Recently Adopted Accounting Standards

In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2013-11 Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11"). The amendments in ASU 2013-11 require entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss ("NOL") carryforward, a similar tax loss, or a tax credit carryforward except when the following exist: (i) an NOL carryforward, a similar tax loss, or a tax credit carryforward is not available as of the reporting date under the governing tax law to settle taxes that would result from the disallowance of the tax position, and (ii) the entity does not intend to use the deferred tax asset for this purpose (provided the tax law permits a choice). If any of these conditions exist, entities should present an unrecognized tax benefit in the financial statements as a liability and should not net the unrecognized tax benefit with a deferred tax asset. ASU 2013-11 is effective for interim and annual periods beginning after December 15, 2013. The Company does not believe that the adoption of ASU 2013-11 will have a material impact on its results of operations when adopted in 2014.

In February 2013, the FASB issued Accounting Standards Update No. 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This guidance is intended to provide

Significant Non-cash Transactions

The purchase price for the Company’s acquisition of UNIK included $991 of contingent consideration for future performance milestones (discussed further in Note 3). On December 31, 2012, the Company estimated that approximately $313 would be paid on projected performance milestones. On June 30, 2013, the Company revised the estimate based on current performance milestones to be approximately $511, which was paid on July 1, 2013. The purchase price for the Company’s acquisition of rapid! Financial Services included $10,000 of contingent consideration for future performance milestones (discussed further in Note 3). On December 31, 2011, the Company estimated approximately $9,325 as the amount to be paid based on projected performance milestones. During the second quarter of 2012, the Company lowered the estimate to $8,486 and settled the contingent consideration.

3.     Business Acquisitions and Other Intangible Asset Acquisitions

Acquisition of FastCred

On October 15, 2013, the Company's Brazilian 51 percent majority-owned subsidiary UNIK S.A. (“UNIK”) acquired all of the stock of FastCred, a provider of fleet cards to the heavy truck or over-the-road segment of the fleet market, for approximately $12,309, net of cash acquired. The Company purchased FastCred to expand its Fleet Payment Solutions segment. During the fourth quarter of 2013, the Company allocated $4,282 of the cost of the acquisition to goodwill and $12,594 to other intangible assets, primarily customer relationships. The allocation of the purchase price is preliminary as the Company is still reviewing the intangible asset valuation. The total weighted average useful life of the intangible assets acquired from FastCred is 5 years. Goodwill recorded as a result of the FastCred acquisition is not currently deductible for income tax purposes. No pro forma information has been included in these financial statements as the operations of FastCred for the period that they were not part of the Company are not material to the Company’s revenues, net income and earnings per share.

Acquisition of CorporatePay

On May 11, 2012, the Company acquired all of the stock of CorporatePay, a provider of corporate prepaid solutions to the travel industry in the United Kingdom for approximately $27,800, net of cash acquired. The Company purchased CorporatePay to expand its Other Payment Solution segment. During the second quarter of 2012, the Company allocated the purchase price of the acquisition based upon a preliminary estimate of the fair values of the assets acquired and liabilities assumed. During the first quarter of 2013, the Company obtained information to assist in determining the fair values of certain tangible and intangible assets acquired and liabilities assumed as of the CorporatePay acquisition date. Based on such information, the Company retrospectively adjusted the fiscal year 2012 comparative information resulting in an increase in accounts receivable of $508, a decrease in deferred taxes of $32, an increase in intangible assets of $140, a decrease in goodwill of $247, and an increase in accrued expenses of $369. There were no changes to the previously reported consolidated statements of operations or statements of cash flows. With the initial purchase of CorporatePay, the Company established a full valuation allowance of $1,219 on the acquired net operating losses. The Company believes it is more likely than not that the losses will not be utilized. The valuations of all assets and liabilities have been finalized.

Goodwill related to the CorporatePay acquisition is not expected to be deductible for income tax purposes. The results of operations of CorporatePay are reflected in the Other Payment Solutions segment from the date of acquisition.

Acquisition of UNIK

On August 30, 2012, the Company acquired a 51 percent ownership interest in UNIK, a privately-held provider of payroll cards in Brazil. The Company purchased its interest in UNIK to expand its Other Payment Solutions segment. UNIK is a provider of payroll cards, private label and processing services in Brazil specializing in the retail, government and transportation sectors.

The investment was consummated through the purchase of newly issued shares of UNIK for approximately $22,800. The purchase agreement also included a potential contingent consideration component based on performance milestones. Although the contingent consideration was not capped, the Company estimated the amount of the liability, at the time of acquisition, to be approximately $991 at the time of acquisition. On December 31, 2012, the Company revised the estimate based on current performance milestones to be approximately $313. On June 30, 2013, the Company finalized the contingent consideration amount based on current performance milestones and determined it to be approximately $511, which was paid on July 1, 2013. The purchase agreement further provides the Company with a call option which allows the Company to acquire the remaining shares at specific times over a three-year period. Additionally the agreement provides the noncontrolling shares with the right to put their interest back to the Company at specific times. The put options are exercisable at specific dates subject to the achievement of performance hurdles. Pricing for both the call and put options are based upon multiples of UNIK’s trailing twelve month EBITDA. Using the proceeds from the acquisition of UNIK, UNIK paid down approximately $19,600 of existing financing debt. As of December 31, 2013, UNIK has approximately $7,278 of financing debt, classified in other liabilities on the Company’s consolidated balance sheets.

Based on its ownership position, the Company concluded that it has acquired a controlling interest in UNIK. During the third quarter of 2012, the Company allocated the purchase price of the acquisition based upon a preliminary estimate of the fair values of the assets acquired and liabilities assumed. Goodwill associated with the transaction is not expected to be deductible for income tax purposes. In addition, the Company has recognized and measured a redeemable noncontrolling interest. The redeemable noncontrolling interest represents the portion of UNIK’s net assets owned by the noncontrolling shareholders and is presented in the mezzanine section on the Company’s consolidated balance sheets. The results of operations of UNIK are reflected in the Other Payment Solutions segment. During the third quarter of 2013, the Company obtained information to assist in determining the fair values of certain tangible and intangible assets acquired and liabilities assumed as of the UNIK acquisition date. Based on such information, the Company retrospectively adjusted the fiscal year 2012 comparative information resulting in an increase in deferred taxes of $2,243, an increase in goodwill of $4,355, and an increase in accrued expenses of $6,598. There were no changes to the previously reported consolidated statements of operations or statements of cash flows. The valuations of all assets and liabilities have been finalized.

Acquisition of Fleet One

On October 4, 2012, the Company acquired certain assets of Fleet One, a privately-held provider of value-based business payment processing and information management solutions. The Company purchased Fleet One to expand its fuel card and fleet management information services, as well as to accelerate its presence in the over-the-road market.

Fleet One was purchased from the private equity firms of LLR Partners and FTV Capital for approximately $376,258, net of cash acquired. During the fourth quarter of 2012, the Company allocated the purchase price of the acquisition based upon a preliminary estimate of the fair values of the assets acquired and liabilities assumed. During the third quarter of 2013, the Company obtained information to assist in determining the fair values of certain tangible and intangible assets acquired and liabilities assumed as of the Fleet One acquisition date. Based on such information, the Company retrospectively adjusted the fiscal year 2012 comparative information resulting in a decrease in accounts receivable of $47, an increase in deferred taxes of $261, a decrease in goodwill of $407, a decrease in taxes payable of $113 and a decrease in accrued expenses of $80. There were no changes to the previously reported consolidated statements of operations or statements of cash flows. The valuations of all assets and liabilities have been finalized.

The operations at Fleet One contributed net revenues of approximately $14,200 and net earnings of approximately $1,400 from October 4, 2012, through December 31, 2012. The goodwill is expected to be deductible for tax purposes. Operations from Fleet One are reflected in the Fleet Payment Solutions segment from the date of acquisition.

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

Consideration paid (net of cash)	$	376,258
Less:
Accounts receivable	152,527
Accounts payable	(151,647		)
Other tangible liabilities, net	(693		)

Acquisition of rapid! Financial Services LLC

On March 31, 2011, the Company acquired certain assets of rapid! Financial Services LLC (“rapid! PayCard”) for approximately $18,000 including an estimate of contingent consideration for future performance milestones of $10,000. rapid! PayCard is a provider of payroll prepaid cards, e-paystubs and e-W2s, and is focused on small and medium sized businesses. The Company purchased rapid! PayCard to expand its Other Payment Solutions segment. During the first quarter of 2011, the Company allocated the purchase price of the acquisition based upon a preliminary estimate of the fair values of the assets acquired and liabilities assumed. During the first quarter of 2012, the Company finalized the valuation of the intangible assets associated with the trade name. The goodwill is expected to be deductible for tax purposes.

A contingent consideration agreement was entered into in connection with the purchase of rapid! PayCard. Under the terms of the agreement the former owners of rapid! PayCard were entitled to receive additional consideration based upon the achievement of certain performance criteria, measured over the twelve-month period from the date of purchase. During the fourth quarter of 2011, the Company revised the estimate of contingent consideration to approximately $9,325. The resulting impact of this adjustment ($675) was an offset to other operating expense in our Other Payment Solutions segment. During the second quarter of 2012, the Company lowered the estimate to $8,486 and settled the contingent consideration.

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

Consideration (including estimated $10,000, contingent consideration)	$	18,081

The Company’s management has determined that the gross unrealized losses on its investment securities at December 31, 2013 and 2012 are temporary in nature. The Company reviews its investments to identify and evaluate investments that have indications of possible impairment. The Company’s techniques used to measure the fair value of its investments are in Note 15, Fair Value. Factors considered in determining whether a loss is temporary include the length of time and extent to which 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 Company had maturities of available-for-sale securities of $1,192 for the year ended December 31, 2013, $1,551 for the year ended December 31, 2012, and $841 for the year ended December 31, 2011.

The Company adjusted the consolidated balance sheet amount for goodwill and intangible assets at December 31, 2012, and December 31, 2011, to account for the measurement period adjustments related to the CorporatePay, UNIK, Fleet One and rapid! PayCard purchase price allocations.

During the third quarter of 2012, the Company determined that pricing pressure in the prepaid giftcard product in Australia would result in lower future earnings than forecasted at the time of the purchase of WEX Prepaid Cards Australia. On September 30, 2012, the Company recorded an estimated goodwill impairment loss of $16,171 related to the purchase of WEX Prepaid Cards Australia. The Company used a discounted cash flow model of the projected earnings of Wright Express Prepaid Australia, which is a level 3 fair value measurement, to determine the amount of goodwill impairment. This amount was finalized during the fourth quarter of 2012. During the fourth quarter of 2012, the Company recorded a goodwill impairment loss of $1,337, which is a level 3 fair value measurement, related to the purchase of Financial Automation Limited, acquired in August of 2008.

During the third quarter of 2013, the Company determined that the intangible asset recorded for the trade name associated with Wright Express Corporation should be reclassified from an indefinite-lived intangible asset to a definite-lived intangible asset due to the current re-branding efforts of changing from the Wright Express brand to the WEX brand initiated domestically and abroad.

2007 Revolving Credit Facility and 2010 Term Loan Note

On May 22, 2007, the Company entered into a revolving credit facility (the “2007 Revolver”) with a lending syndicate. The 2007 Revolver initially provided for a five-year $350,000 unsecured revolving line of credit. In connection with the 2007 Revolver, the Company paid loan origination fees of $998. These fees were recorded as other assets on the consolidated balance

sheet and were amortized on a straight-line basis (which approximates the effective interest rate method) over the term of the 2007 Revolver. On May 29, 2008, the Company entered into an incremental amendment agreement (the “Incremental Amendment Agreement”) of the 2007 Revolver to increase the aggregate unsecured revolving line-of-credit from $350,000 to $450,000. The Company incurred $1,556 in loan origination fees in conjunction with entering into the Incremental Amendment Agreement. These fees have been recorded as other assets on the consolidated balance sheet and were amortized over the remaining term of the 2007 Revolver.

On July 25, 2010, the Company entered into a $75,000 term credit facility (“2010 term loan”). The rate on the 2010 term loan was 250 basis points above LIBOR. In connection with the 2010 term loan, the Company paid loan origination fees of $2,269. The agreement did not change any of the Company’s existing financial covenants.

The 2007 Revolver and the 2010 term loan were refinanced in 2011 as described below.

2011 Credit Agreement

On May 23, 2011, the Company entered into a credit agreement (the “2011 Credit Agreement”), by and among the Company and certain of its subsidiaries, as borrowers, and Wright Express Card Holdings Australia Pty Ltd, as specified designated borrower, with a lending syndicate. The 2011 Credit Agreement was secured by pledges of the stock of the Company’s foreign subsidiaries. The 2011 Credit Agreement provided for a five-year $200,000 amortizing term loan facility and a five-year $700,000 revolving credit facility with a $100,000 sub-limit for letters of credit. Term loan payments in the amount of $2,500 per quarter began on June 30, 2011, and were scheduled to continue on the last day of each September, December, March and June thereafter, through and including March 31, 2016. On the maturity date for the term agreement, May 23, 2016, the remaining outstanding principal amount of $150,000 would have been due.

As of December 31, 2012, the Company had $621,000 of loans outstanding under the 2011 Credit Agreement (including $182,500 under the term loan and $438,500 under the revolving credit facility). As of December 31, 2012, the Company had posted approximately $2,350 letters of credit as collateral for fuel derivatives and lease agreements. Accordingly, at December 31, 2012, the Company had $264,150 of availability under the 2011 Credit Agreement, subject to the covenants as described below. The Company capitalized approximately $6,200 in loan origination fees in association with this borrowing and wrote-off approximately $700 of previous issuance costs in the second quarter of 2011.

Proceeds from the 2011 Credit Agreement were used to refinance the Company’s existing indebtedness under its 2007 Revolver, and the existing indebtedness under the 2010 term loan. The 2011 Credit Agreement was available for working capital purposes, acquisitions, payment of dividends and other restricted payments, refinancing of indebtedness, and other general corporate purposes.

Amounts outstanding under the 2011 Credit Agreement bears interest at a rate equal to, at the Company’s option, (a) the Eurocurrency Rate, as defined, plus a margin of 1.25 percent to 2.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the highest of (i) the Federal Funds Rate plus 0.50 percent, (ii) the prime rate announced by lead lender, or (iii) the Eurocurrency Rate plus 1.00 percent, in each case plus a margin of 0.25 percent to 1.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA. In addition, the Company agreed to pay a quarterly commitment fee at a rate per annum ranging from 0.20 percent to 0.40 percent of the daily unused portion of the credit facility. Any outstanding loans under the 2011 Credit Agreement would have matured on May 23, 2016.

The 2011 Credit Agreement was replaced in January of 2013 by an Amended and Restated Credit Agreement (the “2013 Credit Agreement”).

2013 Credit Agreement and $400 Million Notes Outstanding

On January 18, 2013, the Company entered into the 2013 Credit Agreement, among the Company, as borrower, Wright Express Card Holdings Australia Pty Ltd, a wholly-owned subsidiary of the Company, as specified designated borrower (“Card Holdings Australia”, and, together with the Company, the “Borrowers”), Bank of America, N.A., as administrative agent and letter of credit issuer (“Bank of America”), and the other lenders party thereto (the “Lenders”). The 2013 Credit Agreement provides for a five-year $300,000 term loan facility, and a five-year $800,000 secured revolving credit facility with a $150,000 sub-limit for letters of credit. The indebtedness covenant under the 2013 Credit Agreement requires that the Company reduce the revolving commitments under the 2013 Credit Agreement on a dollar-for-dollar basis to the extent that the Company issues more than $300,000 in principal amount of senior or senior subordinated notes of the Company. Subject to certain conditions, including obtaining relevant commitments, the Company has the option to increase the facility by up to an additional $100,000.

The 2013 Credit Agreement amends, restates and substitutes for the 2011 Credit Agreement, among the Company, Card Holdings Australia, Bank of America, as administrative agent, the joint lead arrangers and other agents named therein, and a syndicate of lenders. The 2013 Credit Agreement increases the outstanding amount of the term loan from $185,000 to $300,000 and increases the amount of the revolving loan from $700,000 to $800,000. A portion of the indebtedness owing under the 2013 Credit Agreement is the same indebtedness as formerly evidenced by the 2011 Credit Agreement.

Amounts outstanding under the 2013 Credit Agreement bore interest at a rate equal to, at the Company’s option, (a) the Eurocurrency Rate, as defined, plus a margin of 1.25 percent to 2.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the highest of (i) the Federal Funds Rate plus 0.50 percent, (ii) the prime rate announced by lead lender, and (iii) the Eurocurrency Rate plus 1.00 percent, in each case plus a margin of 0.25 percent to 1.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA. In addition, the Company has agreed to pay a quarterly commitment fee at a rate per annum ranging from 0.20 percent to 0.40 percent of the daily unused portion of the credit facility. Any outstanding loans under the 2013 Credit Agreement mature in January of 2018, unless extended pursuant to the terms of the 2013 Credit Agreement.

On January 30, 2013, the Company, completed a $400,000 offering in 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 an indenture dated as of January 30, 2013 (the “Indenture”) among the Company, the guarantors listed therein, and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”).

The Notes will mature on February 1, 2023, and interest will accrue at the rate of 4.750 percent per annum. Interest is 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 unsecured 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 be subject to many of the restrictive covenants in the indenture governing the Notes.

The Notes and guarantees described above are general senior unsecured 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 junior in right of payment to all of the Company’s existing and future secured debt, including the Company’s 2013 Credit Agreement, to the extent of the value of the collateral securing such debt. 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 may redeem 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.

In addition, at any time prior to February 1, 2016, the Company may, subject to certain conditions, redeem up to 35 percent of the Notes from the proceeds of certain equity offerings at a redemption price of 104.75% percent of the principal amount, plus 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.

Under the terms of the 2013 Credit Agreement, the $800,000 secured revolving credit facility was reduced to $700,000 as a result of the $400,000 Notes offering.

The Company capitalized approximately $15,547 in loan origination fees in association with these borrowings and wrote-off approximately $1,000 of previous issuance costs in the first quarter of 2013.

The Company used the net proceeds of this offering to repay the outstanding amount under the revolving portion of its 2013 Credit Agreement and to pay related fees and expenses and for general corporate purposes.

As of December 31, 2013, the Company had $685,000 of loans outstanding. This includes $285,000 under the 2013 Credit Agreement and $400,000 of notes outstanding. As of December 31, 2013, the interest rate for the borrowings under the 2013 Credit Agreement was 1.93 percent

As of December 31, 2013, the Company has posted approximately $11,947 letters of credit as collateral for lease agreements and virtual card and fuel payment processing activity at our foreign subsidiaries. Accordingly, at December 31, 2013, the Company had $688,000 of availability under the 2013 Credit Agreement, subject to the covenants as described below.

The Company had approximately $561,469 of state and $31,489 of foreign net operating loss carry forwards at December 31, 2013 and approximately $462,396 of state and $22,183 of foreign net operating loss carry forwards at December 31, 2012. These U.S. losses expire at various times through 2033. Foreign losses in Brazil and the U.K. have indefinite carry forward periods. The Company has established a valuation allowance primarily for acquired net operating losses in the UK for which the Company has determined it is more likely than not that the losses will not be utilized. No valuation allowances have been established for all other deferred assets as the Company believes it is more likely than not that its deferred tax assets will be utilized within the carry forward periods.

Undistributed earnings of certain foreign subsidiaries of the Company amounted to $4,665 at December 31, 2013, and $1,756 at December 31, 2012. These earnings are considered to be indefinitely reinvested, and accordingly, no U.S. federal and state income taxes have been provided thereon. Upon distribution of these earnings in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. The Company has determined that the amount of taxes attributable to these undistributed earnings is not practicably determinable.

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.

The Company files a consolidated federal income tax return in the United States, as well as consolidated or separate income tax returns in most states. The Company also files consolidated or separate income tax returns in non-U.S. jurisdictions where required. In the normal course of business, the Company is no longer subject to income tax examination for the years prior to 2010.

A reconciliation of the beginning and ending amount of unrecognized tax benefits excluding interest and penalties is as follows:

	Year ended December 31,
	2013			2012		2011
Beginning balance	$	6,176		$	6,059	$	—
Increases related to prior year tax position	—			—		6,059
(Decreases) increases related to prior year tax positions, due to foreign currency exchange	(893		)	117		—
Ending balance	$	5,283		$	6,176	$	6,059

At December 31, 2013, the Company had $6,908 of net unrecognized tax benefits. If recognized, $6,908 would reduce the Company’s effective tax rate. The Company does not anticipate settling any unrecognized tax benefit within the next 12 months.

The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The Company has accrued $1,625 as of December 31, 2013, $1,313 as of December 31, 2012 and $500 as of December 31, 2011, for penalties and interest related to uncertain tax positions.

On June 29, 2012, tax legislation was enacted in Australia that affected the tax deductibility of certain intangible assets acquired as part of the 2010 acquisition of Wright Express Australia. The Company performed a review of the legislation to determine which of these intangible assets would be impacted. Based upon this review the Company recorded a tax charge of $31,432 in June of 2012 to reflect these impacts. The Company wrote-off an associated refund claim payable to the former shareholder of RD Card Holding Australia for $9,750, included in non-operating income. This payable was contingent on the receipt of the tax refunds generated by tax deductions associated with the amortization of above mentioned intangible assets.

During 2012, the Company recorded an impairment charge related to goodwill in the amount of $17,508. This charge did not result in any tax provision benefit. The Company also recorded a tax charge of approximately $2,400 due to the impact of a retroactive tax legislation enacted on September 8, 2012 in Australia. This legislation impacted the potential deductibility of intercompany interest expense allowable in past and future tax years and hence resulted in a discrete charge in our recorded tax expense in the current year and a higher Australian effective tax rate in future periods.

13.  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. The estimated total payments owed to Cendant Corporation based on facts available at that time, was reflected as a liability titled “Amounts due under tax receivable agreement.”

The amount of these estimated future payments 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. 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 income statement as changes in amounts due under tax receivable agreement.

(in thousands, except per share data)

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.

For each year presented, there had been reassessment of the blended tax rates that are projected into the future. The net future benefits increased, which increased the associated liability to Wyndham, resulting in a $33, $2,089 and $715 charge to non-operating expense for the years ended December 31, 2013, 2012 and 2011, respectively.

14.  Employee Benefit Plans

The Company sponsors a 401(k) retirement and savings plan. Employees are eligible to 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 $2,991, $2,295 and $2,094 in matching funds to the plan for the years ended December 31, 2013, 2012 and 2011, respectively.

During 2012, the Company acquired Fleet One which, as of the date of the acquisition, had its own employee savings plan, the Fleet One 401(k) Retirement Plan (“Fleet One Plan”). As of December 31, 2012, the Fleet One 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 Fleet One Plan. Subsequent to year end, net assets available for benefits totaling $2,787 were received by the plan on January 15, 2013, in a transfer from the Fleet One Plan. On January 1, 2013, Fleet One 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 $4,339 at December 31, 2013, and $2,921 at December 31, 2012. These amounts are included in other liabilities on the consolidated balance sheet. 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 $4,339 at December 31, 2013, and $2,921 at December 31, 2012. Such amounts are included in other assets on the consolidated balance sheet.

15.  Fair Value

The Company holds mortgage-backed and other asset-backed securities, fixed income and equity securities, derivatives and certain other financial instruments which 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. The Company carries certain of its liabilities at fair value, including its derivative liabilities. In determining the fair value of the Company’s obligations, various factors are considered including: closing exchange or over-the-counter market price quotations; time value and volatility factors underlying options and derivatives; price activity for equivalent instruments; the Company’s own-credit standing; and counterparty credit risk.

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:

81

WEX INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(in thousands, except per share data)

• 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.

The following table presents the Company’s assets and liabilities that are measured at fair value and the related hierarchy levels for 2013:

Gains and losses on the change of estimate on the contingent consideration are included in other expenses and and loss of foreign currency transactions on the consolidated statements of income.

Available-for-sale securities and executive deferred compensation plan trust

When available, the Company uses quoted market prices to determine the fair value of available-for-sale securities; such items are classified in Level 1 of the fair-value hierarchy. These securities primarily consist of exchange-traded equity securities.

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 classified as Level 2. The obligations related to the deferred compensation plan trust are classified as Level 1 of the fair value hierarchy because the fair value is determined using quoted prices for identical instruments in active markets.

Fuel price derivatives

The majority of derivatives entered into by the Company are executed over-the-counter and are valued using internal valuation techniques as no quoted market prices exist for such instruments. The valuation technique and inputs depend on the type of derivative and the nature of the underlying instrument. The principal technique used to value these instruments is a comparison of the spot price of the underlying instrument to its related futures curve adjusted for the Company’s assumptions of volatility and present value, where appropriate. The fair values of derivative contracts reflect the expected cash the Company will pay or receive upon settlement of the respective contracts.

The key inputs depend upon the type of derivative and the nature of the underlying instrument and include interest rate yield curves, the spot price of the underlying instrument, volatility, and correlation. The item is placed in either Level 2 or Level 3 depending on the observability of the significant inputs to the model. Correlation and items with longer tenures are generally less observable.

Fuel price derivatives – diesel. The assumptions used in the valuation of the diesel fuel price derivatives use both observable and unobservable inputs. There is a lack of price transparency with respect to forward prices for diesel fuel. Such unobservable inputs are significant to the diesel fuel derivative contact valuation methodology.

Quantitative Information About Level 3 Fair Value Measurements. The significant unobservable inputs used in the fair value measurement of the Company’s diesel fuel price derivative instruments designated as Level 3 are as follows:

	Fair Value at December 31, 2013		Valuation Technique	Unobservable Input	Range $ per gallon
Fuel price derivatives – diesel	$	2,142	Option model	Future retail price of diesel fuel after December 31, 2013	3.71 – 3.94

Sensitivity To Changes In Significant Unobservable Inputs. As presented in the table above, the significant unobservable inputs used in the fair value measurement of the Company’s diesel fuel price derivative instruments are the future retail price of

84

WEX INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

diesel fuel from the first quarter of 2014 through the second quarter of 2015. Significant changes in these unobservable inputs in isolation would result in a significant change in the fair value measurement.

Contingent consideration

The Company classified its liability for contingent consideration related to its acquisition of UNIK within Level 3 of the fair value hierarchy because the fair value was determined using significant unobservable inputs, which include the projected revenues of UNIK over a four month period. These assumptions included assessing the probability of meeting certain milestones required to earn the contingent consideration.

On June 30, 2013, the Company finalized the contingent consideration amount based on current performance milestones and determined it to be approximately $511, which was paid on July 1, 2013.

The Company classified its liability for contingent consideration related to its acquisition of rapid! PayCard within Level 3 of the fair value hierarchy because the fair value is determined using significant unobservable inputs, which include the projected revenues of rapid! PayCard over a twelve month period ending on March 31, 2012. On March 31, 2012, the amount due was determined to be $8,486 and was paid on April 30, 2012.

16.  Noncontrolling interest

On August 30, 2012, the Company acquired a 51 percent ownership interest in UNIK, a provider of payroll cards in Brazil. The purchase agreement provides the Company with a call option which allows the Company to acquire the remaining shares at specific times over a three-year period. Additionally, the agreement provides the noncontrolling shareholders with the right to put their interest back to the Company at specific times. This redeemable noncontrolling interest was measured at fair value at the date of acquisition.  The Company believes that it is probable that the noncontrolling interest in UNIK will become redeemable. However, as of December 31, 2013, the Company has determined that no accretion to the fair value of the minority interest is necessary as the fair value of the put option at the time of redemption is expected to approximates the value of the minority interest.

The redeemable noncontrolling interest is reported on the Company’s consolidated balance sheets as “Redeemable noncontrolling interest.”

A reconciliation of redeemable noncontrolling interests for the years ended December 31, 2013 and 2012, is as follows:

	2013			2012
Balance, beginning of period	$	21,662		$	—

On November 8, 2013, the Company announced that it plans to acquire the assets of ExxonMobil’s European commercial fuel card (“Esso Card”) program through a majority owned subsidiary, WEX Europe Services Limited. The Company formed this entity during 2013 and has 75 percent ownership.

WEX INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(in thousands, except per share data)

The Company is involved in pending litigation in the ordinary course of business. In the opinion of management, such litigation will not have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

Extension of Credit to Customers

The Company had aggregate commitments of approximately $5,650,000 at December 31, 2013, and $4,665,000 at December 31, 2012, 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. These amounts are not recorded on the consolidated balance sheet.

Operating Leases

The Company leases office space, equipment, and vehicles under non-cancelable operating leases that expire at various dates through 2019. 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 $7,257 for the year ended December 31, 2013, $5,601 for the year ended December 31, 2012 and $4,794 for the year ended December 31, 2011. 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 expense related to information technology hardware and software leases totaled $8,249 for the year ended December 31, 2013, $6,959 for the year ended December 31, 2012, and $5,342 for the year ended December 31, 2011. 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:

	Payment
2014	$	7,567
2015	6,546
2016	4,170
2017	3,351
2018	2,952
2019 and thereafter	550
Total	$	25,136

18.  Accumulated Other Comprehensive Income

A reconciliation of accumulated other comprehensive income for the twelve month periods ended December 31, 2013 and 2012, is as follows:

	2013						2012
	Unrealized Gains and Losses on Available- for-Sale Securities			Foreign Currency Items			Unrealized Gains and Losses on Available- for-Sale Securities			Interest Rate Swap			Foreign Currency Items
Beginning balance	$	197		$	37,182		$	200		$	(60	)	$	30,448
Other comprehensive (loss) income	(630		)	(52,244		)	(3		)	60			6,734
Ending balance	$	(433	)	$	(15,062	)	$	197		$	—		$	37,182

No significant amounts were reclassified from accumulated other comprehensive income in the periods presented.

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 accumulated unrealized loss as of December 31, 2013 was $173 and the total tax effect on accumulated unrealized gain was $874 as of December 31, 2012.

19.  Cash and Dividend Restrictions

86

WEX INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(in thousands, except per share data)

Cash

WEX Bank is required to maintain reserves against certain customer deposits by keeping cash on hand or balances with the Federal Reserve Bank. The required amount of those reserves at December 31, 2013 and 2012 was $28,384 and $26,246, respectively.

Dividends

The Company has certain restrictions on the dividends it may pay under its revolving credit agreement. If the Company’s leverage ratio is higher than 1.75, after execution of a restricted payment, the Company may pay no more than $25,000 per annum for restricted payments, including dividends. 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 the years ended December 31, 2013, 2012, and 2011.

20.  Stock-Based Compensation

In May of 2010, the Company adopted the WEX Inc. 2010 Equity Incentive Plan (the “Plan”). This Plan replaced the Company’s 2005 Equity and Incentive Plan. The Plan, which is stockholder-approved, permits 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 for up to 3,800 shares of common stock. The Company believes that such awards increase efforts on behalf of the Company and promote the success of the Company’s business. On December 31, 2013, the Company had four stock-based compensation programs, which are described below. The compensation cost that has been charged against income for these programs totals $9,429 for 2013, $11,016 for 2012, and $9,367 for 2011.

Restricted Stock Units

The Company awards restricted stock units (“RSU”) to non-employee directors and certain employees periodically under the Plan. An RSU is a right granted to receive stock at the end of a specified period. RSU awards generally vest evenly over a period of three or four years. The awards 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”).

A summary of the status of the Company’s RSUs as of December 31, 2013, and changes during the year then ended is presented below:

^(b)  The Company has elected to pay cash equal to the minimum amount required to be withheld for income tax purposes instead of issuing the shares of common stock. The cash is remitted to the appropriate taxing authority.

As of December 31, 2013, there was $5,652 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted as RSUs. That cost is expected to be recognized over a weighted-average period of 1.1 years. The total grant-date fair value of shares granted was $9,757 during 2013, $7,830 during 2012, and $4,107 during 2011. The total fair value of shares vested (issued) was $5,259 during 2013, $6,347 during 2012, and $5,435 during 2011.

Deferred Stock Units

Under the Plan, the Company also grants deferred stock units (“DSU”) to non-employee directors. A DSU is a fully vested right to receive stock at a certain point in time in the future. DSUs do not require any future service or performance obligations to be met. DSUs may be granted immediately or may initially be granted as RSUs which become DSUs once a previously determined service obligation has been met. The fair value of each granted DSU award is based on the closing market price of the Company’s stock on the grant date as reported by the NYSE.

A summary of the status of the Company’s DSUs as of December 31, 2013, and changes during the year is presented below:

	Units	Weighted- Average Grant-Date Fair Value
Deferred Stock Units
Balance at January 1, 2013	89	$	25.16
Awards	1	$	80.91
Converted from RSUs	3	$	43.48
Balance at December 31, 2013	93	$	26.35

There is no unrecognized compensation cost related to awards granted as, or converted to, DSUs. The Company has determined that the award was earned when granted and it is expensed at that time. The total fair value of shares granted and vested was $137 during 2013, $150 during 2012, and $173 during 2011.

Performance Based Restricted Stock Units

The Company also awards performance based restricted stock units (“PBRSUs”) to employees periodically under the Plan. A PBRSU is a right granted to receive stock at the end of a specified period. In a PBRSU, the number of shares earned varies based upon meeting certain performance goals, including revenue and earnings in excess of targets. PBRSU awards generally have performance goals tracking a one to four year period, 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.

A summary of the status of certain of the Company’s PBRSUs at threshold and target performance as of December 31, 2013, and changes during the year then ended is presented below:

The range of unrecognized compensation cost related to the PBRSU awards is from $635 at threshold (25 percent below targeted performance), $2,601 at target (100 percent of targeted performance) and up to $5,082 at maximum (200 percent of targeted performance), as of December 31, 2013, depending on whether certain performance conditions are met. That cost is expected to be recognized over a weighted-average period of 1.4 years The total grant-date fair value of shares granted at target was $5,356 during 2013, $4,308 during 2012, and $4,157 during 2011. The total grant-date fair value of shares converted to RSUs and subsequently vested was $9,075 during 2013, $1,382 during 2012, and $327 during 2011.

Stock Options

The fair value of each option award is estimated on the grant date using a Black-Scholes-Merton option-pricing model that uses the assumptions noted in the following table. The expected term of the options represents the period of time that options granted are expected to be outstanding. Expected volatilities are based on implied volatilities from traded options on the Company’s stock, historical volatility of the Company’s stock, and other factors. The risk-free interest rate for the period matching the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The dividend yield is the calculated yield on the Company’s stock at the time of the grant.

The stock options granted under the plan related to the Company’s employees consisted of:

21.  Segment Information

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. The operating segments are reviewed separately because each operating segment represents a strategic business unit that generally offers different products and serves different markets.

The Company’s chief operating decision maker evaluates the operating results of the Company’s reportable segments based upon revenues and “adjusted net income,” which is defined by the Company as net income adjusted for fair value changes of derivative instruments, the amortization of purchased intangibles, the net impact of tax rate changes on the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(in thousands, except per share data)

Company’s deferred tax asset and related changes in the tax-receivable agreement, deferred loan costs associated with the extinguishment of debt, certain non-cash asset impairment charges, the gains on the extinguishment of a portion of the tax receivable agreement and adjustments related to the noncontrolling interest. These adjustments are reflected net of the tax impact.

The Company operates in two reportable segments, Fleet Payment Solutions and Other Payment Solutions. The Fleet Payment Solutions segment provides customers with payment and transaction processing services specifically designed for the needs of vehicle fleet customers. This segment also provides information management services to these fleet customers. The Other Payment Solutions segment provides customers with a payment processing solution for their corporate purchasing and transaction monitoring needs. Revenue in this segment is derived from our corporate purchase cards and virtual and prepaid card products. The corporate purchase card products are used by businesses to facilitate purchases of products and to utilize the Company’s information management capabilities. Revenue from one customer represents approximately 11 percent of the Company’s total 2013 revenue. Revenue from this customer is included in Other Payment Solutions revenue.

The accounting policies of the reportable segments are generally the same as those described in the summary of significant accounting policies.

Financing interest expense and net realized and unrealized losses on derivative instruments are not allocated to the Other Payment Solutions segment in the computation of segment results for internal evaluation purposes. Total assets are not allocated to the segments.

The following table presents the Company’s reportable segment results for the years ended December 31, 2013, 2012 and 2011:

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 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. 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 (1992) issued by The Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control – Integrated Framework (1992), management concluded that WEX Inc.’s internal control over financial reporting was effective as of December 31, 2013.

The effectiveness of our internal control over financial reporting as of December 31, 2013, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the fiscal quarter ended December 31, 2013, that have materially affected, or are reasonably likely to materially affect, the Company’s 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

We have audited the internal control over financial reporting of WEX Inc. and subsidiaries (the “Company”) as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel 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 the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on the criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2013 of the Company and our report dated February 27, 2014 expressed an unqualified opinion on those financial statements.

Noncontrolling Interest [Abstract]

Noncontrolling Interest

Noncontrolling interest

On August 30, 2012, the Company acquired a 51 percent ownership interest in UNIK, a provider of payroll cards in Brazil. The purchase agreement provides the Company with a call option which allows the Company to acquire the remaining shares at specific times over a three-year period. Additionally, the agreement provides the noncontrolling shareholders with the right to put their interest back to the Company at specific times. This redeemable noncontrolling interest was measured at fair value at the date of acquisition.  The Company believes that it is probable that the noncontrolling interest in UNIK will become redeemable. However, as of December 31, 2013, the Company has determined that no accretion to the fair value of the minority interest is necessary as the fair value of the put option at the time of redemption is expected to approximates the value of the minority interest.

The redeemable noncontrolling interest is reported on the Company’s consolidated balance sheets as “Redeemable noncontrolling interest.”

A reconciliation of redeemable noncontrolling interests for the years ended December 31, 2013 and 2012, is as follows:

	2013			2012
Balance, beginning of period	$	21,662		$	—
Acquisition of subsidiary at fair value	—			21,904
Net loss attributable to redeemable noncontrolling interest	(401		)	(213		)
Currency translation adjustment	(2,532		)	(29		)
Ending balance	$	18,729		21,662

On November 8, 2013, the Company announced that it plans to acquire the assets of ExxonMobil’s European commercial fuel card (“Esso Card”) program through a majority owned subsidiary, WEX Europe Services Limited. The Company formed this entity during 2013 and has 75 percent ownership.

A reconciliation of noncontrolling interest for the years ended December 31, 2013 is as follows:

Stock-Based Compensation

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

Stock-Based Compensation

In May of 2010, the Company adopted the WEX Inc. 2010 Equity Incentive Plan (the “Plan”). This Plan replaced the Company’s 2005 Equity and Incentive Plan. The Plan, which is stockholder-approved, permits 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 for up to 3,800 shares of common stock. The Company believes that such awards increase efforts on behalf of the Company and promote the success of the Company’s business. On December 31, 2013, the Company had four stock-based compensation programs, which are described below. The compensation cost that has been charged against income for these programs totals $9,429 for 2013, $11,016 for 2012, and $9,367 for 2011.

Restricted Stock Units

The Company awards restricted stock units (“RSU”) to non-employee directors and certain employees periodically under the Plan. An RSU is a right granted to receive stock at the end of a specified period. RSU awards generally vest evenly over a period of three or four years. The awards 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”).

A summary of the status of the Company’s RSUs as of December 31, 2013, and changes during the year then ended is presented below:

	Units		Weighted- Average Grant- Date Fair Value
Restricted Stock Units
Balance at January 1, 2013	185		$	51.08
Granted	111		$	88.01
Vested – shares issued	(73	)	$	71.81
Vested – shares deferred (a)	(3	)	$	43.48
Forfeited	(8	)	$	60.80
Withheld for taxes (b)	(35	)	$	49.63
Balance at December 31, 2013	177		$	67.28

^(a)  The Company issued fully vested and non-forfeitable restricted stock units to certain non-employee directors and certain employees that are payable in shares of the Company’s common stock at a later date as specified by the award (deferred stock units or “DSUs”).

^(b)  The Company has elected to pay cash equal to the minimum amount required to be withheld for income tax purposes instead of issuing the shares of common stock. The cash is remitted to the appropriate taxing authority.

As of December 31, 2013, there was $5,652 of total unrecognized compensation cost related to nonvested share-based compensation arrangements granted as RSUs. That cost is expected to be recognized over a weighted-average period of 1.1 years. The total grant-date fair value of shares granted was $9,757 during 2013, $7,830 during 2012, and $4,107 during 2011. The total fair value of shares vested (issued) was $5,259 during 2013, $6,347 during 2012, and $5,435 during 2011.

Deferred Stock Units

Under the Plan, the Company also grants deferred stock units (“DSU”) to non-employee directors. A DSU is a fully vested right to receive stock at a certain point in time in the future. DSUs do not require any future service or performance obligations to be met. DSUs may be granted immediately or may initially be granted as RSUs which become DSUs once a previously determined service obligation has been met. The fair value of each granted DSU award is based on the closing market price of the Company’s stock on the grant date as reported by the NYSE.

A summary of the status of the Company’s DSUs as of December 31, 2013, and changes during the year is presented below:

	Units	Weighted- Average Grant-Date Fair Value
Deferred Stock Units
Balance at January 1, 2013	89	$	25.16
Awards	1	$	80.91
Converted from RSUs	3	$	43.48
Balance at December 31, 2013	93	$	26.35

There is no unrecognized compensation cost related to awards granted as, or converted to, DSUs. The Company has determined that the award was earned when granted and it is expensed at that time. The total fair value of shares granted and vested was $137 during 2013, $150 during 2012, and $173 during 2011.

Performance Based Restricted Stock Units

The Company also awards performance based restricted stock units (“PBRSUs”) to employees periodically under the Plan. A PBRSU is a right granted to receive stock at the end of a specified period. In a PBRSU, the number of shares earned varies based upon meeting certain performance goals, including revenue and earnings in excess of targets. PBRSU awards generally have performance goals tracking a one to four year period, 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.

A summary of the status of certain of the Company’s PBRSUs at threshold and target performance as of December 31, 2013, and changes during the year then ended is presented below:

	Units at Threshold		Units at Target		Units at Maximum		Weighted- Average Grant-Date Fair Value
Performance Based Restricted Stock Units
Balance at January 1, 2013	106		211		422		$	41.39
Granted	17		69		135		$	77.95
Forfeited	(1	)	(2	)	(4	)	$	78.24
Canceled / Converted to RSUs	(106	)	(211	)	(422	)	$	40.14
Balance at December 31, 2013	16		67		131		$	77.94

The range of unrecognized compensation cost related to the PBRSU awards is from $635 at threshold (25 percent below targeted performance), $2,601 at target (100 percent of targeted performance) and up to $5,082 at maximum (200 percent of targeted performance), as of December 31, 2013, depending on whether certain performance conditions are met. That cost is expected to be recognized over a weighted-average period of 1.4 years The total grant-date fair value of shares granted at target was $5,356 during 2013, $4,308 during 2012, and $4,157 during 2011. The total grant-date fair value of shares converted to RSUs and subsequently vested was $9,075 during 2013, $1,382 during 2012, and $327 during 2011.

Stock Options

The fair value of each option award is estimated on the grant date using a Black-Scholes-Merton option-pricing model that uses the assumptions noted in the following table. The expected term of the options represents the period of time that options granted are expected to be outstanding. Expected volatilities are based on implied volatilities from traded options on the Company’s stock, historical volatility of the Company’s stock, and other factors. The risk-free interest rate for the period matching the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The dividend yield is the calculated yield on the Company’s stock at the time of the grant.

The stock options granted under the plan related to the Company’s employees consisted of:

	Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value
Stock Options
Outstanding at January 1, 2013	119		$	19.65

Vested and expected to vest at December 31, 2013	49		$	13.59	3.17	$	4,159

The total intrinsic value of options exercised during the years ended December 31, 2013, 2012 and 2011 was $3,632, $10,555 and $7,829, respectively. No options have been granted since March of 2010.

Cash and Dividend Restrictions

Cash and Dividend Restrictions

Cash

WEX Bank is required to maintain reserves against certain customer deposits by keeping cash on hand or balances with the Federal Reserve Bank. The required amount of those reserves at December 31, 2013 and 2012 was $28,384 and $26,246, respectively.

Dividends

The Company has certain restrictions on the dividends it may pay under its revolving credit agreement. If the Company’s leverage ratio is higher than 1.75, after execution of a restricted payment, the Company may pay no more than $25,000 per annum for restricted payments, including dividends. 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 the years ended December 31, 2013, 2012, and 2011.

Segment Reporting [Abstract]

Segment Information

Segment Information

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its Chief Executive Officer. The operating segments are reviewed separately because each operating segment represents a strategic business unit that generally offers different products and serves different markets.

The Company’s chief operating decision maker evaluates the operating results of the Company’s reportable segments based upon revenues and “adjusted net income,” which is defined by the Company as net income adjusted for fair value changes of derivative instruments, the amortization of purchased intangibles, the net impact of tax rate changes on the Company’s deferred tax asset and related changes in the tax-receivable agreement, deferred loan costs associated with the extinguishment of debt, certain non-cash asset impairment charges, the gains on the extinguishment of a portion of the tax receivable agreement and adjustments related to the noncontrolling interest. These adjustments are reflected net of the tax impact.

The Company operates in two reportable segments, Fleet Payment Solutions and Other Payment Solutions. The Fleet Payment Solutions segment provides customers with payment and transaction processing services specifically designed for the needs of vehicle fleet customers. This segment also provides information management services to these fleet customers. The Other Payment Solutions segment provides customers with a payment processing solution for their corporate purchasing and transaction monitoring needs. Revenue in this segment is derived from our corporate purchase cards and virtual and prepaid card products. The corporate purchase card products are used by businesses to facilitate purchases of products and to utilize the Company’s information management capabilities. Revenue from one customer represents approximately 11 percent of the Company’s total 2013 revenue. Revenue from this customer is included in Other Payment Solutions revenue.

The accounting policies of the reportable segments are generally the same as those described in the summary of significant accounting policies.

Financing interest expense and net realized and unrealized losses on derivative instruments are not allocated to the Other Payment Solutions segment in the computation of segment results for internal evaluation purposes. Total assets are not allocated to the segments.

The following table presents the Company’s reportable segment results for the years ended December 31, 2013, 2012 and 2011:

The tax impact of the foregoing adjustments is the difference between the Company’s GAAP tax provision and a pro forma tax provision based upon the Company’s adjusted net income before taxes. The methodology utilized for calculating the Company’s adjusted net income tax provision is the same methodology utilized in calculating the Company’s GAAP tax provision.

Business Description

Business Description

WEX Inc. (“Company”) is a provider of corporate card payment solutions. The Company provides products and services that meet the needs of businesses in various geographic regions including North and South America, Asia Pacific and Europe. The Company’s Fleet Payment Solutions and Other Payment Solutions segments provide its customers with security and control for complex payments across a wide spectrum of business sectors. The Company markets its products and services directly, as well as through strategic relationships which include major oil companies, fuel retailers and vehicle maintenance providers.

Basis of Presentation

Basis of Presentation

The accompanying consolidated financial statements of WEX Inc. for the years ended December 31, 2013, 2012 and 2011, include the accounts of WEX Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

The Company adjusted the consolidated balance sheet amounts as of December 31, 2012, to account for the measurement period adjustments related to the CorporatePay, UNIK and Fleet One purchase price allocations discussed in Note 3, Business Acquisitions, and Other Intangible Asset Acquisitions below. The Company adjusted the statement of stockholders' equity amounts as of December 31, 2010, and for the years ended December 31, 2011 and 2012, to present treasury shares purchased and deferred stock units vested. The Company adjusted the statements of cash flow for the years ended December 31, 2011 and 2012, to combine acquisitions and investments into one single line item presentation.

The presentation of the Company’s consolidated balance sheet as of December 31, 2012 has been corrected for an immaterial error in the classification of foreign deferred tax liabilities. As of December 31, 2012, the foreign jurisdiction deferred tax liability balance was erroneously netted with the domestic deferred tax asset balance and presented on the consolidated balance sheet as a deferred tax asset. This correction of the error resulted in an increase in deferred tax assets and total assets of $18,407 and a corresponding increase in deferred tax liabilities, total liabilities, and total liabilities and stockholders’ equity of $18,407. The result of this correction did not impact the Company’s consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for any period presented.

Use of Estimates and Assumptions

Use of Estimates and Assumptions

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

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 market value. Cash equivalents include federal funds sold, which are unsecured short-term investments entered into with financial institutions.

Accounts Receivable and Reserve for Credit Losses

Accounts Receivable and Reserve for Credit Losses

Accounts receivable balances are 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, 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.

Available-for-sale Securities

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 sheet in accumulated other comprehensive income (loss). Realized gains and losses and declines in fair value determined to be other-than-temporary on available-for-sale securities are included in non-operating revenues and 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 revenues. 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

Derivatives

The Company uses derivative instruments as part of its overall strategy to manage its exposure to fluctuations in fuel prices and to reduce the impact of interest rate volatility. All derivatives are recorded at fair value on the consolidated balance sheet.

The Company’s fuel price derivative instruments do not qualify for hedge accounting treatment; therefore, gains or losses related to fuel price derivative instruments, both realized and unrealized, are recognized in earnings. These instruments are presented on the consolidated balance sheet as fuel price derivatives, at fair value. For the purposes of cash flow presentation, realized gains or losses are included in operating cash flows, as they are intended to hedge operating cash flows.

In prior years, the Company used interest rate derivatives designated as cash flow hedges and, accordingly, the change in fair value associated with the effective portion of these derivative instruments that qualified for hedge accounting treatment was recorded as a component of other comprehensive income (loss) and the ineffective portion, if any, was reported in earnings. Amounts included in other comprehensive income (loss) were reclassified into earnings in the same period during which the hedged item affected earnings. These instruments were presented as either other assets or accrued expenses on the consolidated balance sheet.

The Company assessed the hedge effectiveness of the interest rate swaps in accordance with the requirements outlined in the accounting standards. For these hedges, management documented, both at inception and over the life of the hedge, at least quarterly, its analysis of actual and expected hedge effectiveness. For those hedging relationships in which the critical terms of the entire debt instrument and the derivative were identical, and the creditworthiness of the counterparty to the hedging instrument remained sound, there was no hedge ineffectiveness as long as those conditions continue to be met. As of December 31, 2013, the Company does not have any interest rate swaps outstanding.

Property and Equipment

Property and Equipment

Property and equipment are stated at cost less 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. Leasehold improvements are primarily depreciated using the straight-line method over the lesser of the useful life of the asset or over the remaining lease term.

Below is the estimated useful lives for assets placed in service during 2013 and beyond:

	Estimated Useful Lives
Furniture, fixtures and equipment	3 to 5 years
Computer software	18 months to 7 years
Leasehold improvements	up to 5 years

Capitalized Software

Capitalized Software

The Company develops software that is used in providing 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. Software development costs are capitalized beginning when technological feasibility of the software has been established. Costs incurred prior to establishing technological feasibility are expensed as incurred. Technological feasibility is established when the Company has completed all planning, designing, coding and testing activities that are necessary to determine that the software can be produced to meet its design specifications, including functions, features and technical performance requirements. Capitalization of costs ceases when the software is ready for its intended use. 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:

	Year ended December 31,
	2013		2012		2011
Amounts capitalized for internal-use computer software	$	18,360	$	17,341	$	17,463
Amounts expensed for amortization of internal-use computer software	18,830		20,694		18,690

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets

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 would record 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.

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 a variety of methodologies to estimate fair value, but primarily relies on discounted cash flow analyses. 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 fair value. Impairment charges are recorded in depreciation, amortization and impairment expense on the consolidated statements of income. The Company's annual goodwill and intangible asset impairment tests performed as of October 1, 2013 did not identify any impairment. The Company’s annual goodwill and intangible assets impairment tests, performed as of October 1, 2012, identified an impairment of $1,337 of goodwill associated with the acquisition of Financial Automation Limited, acquired in August of 2008. On September 30, 2012, the Company impaired $16,171 of goodwill associated with Wright Express Australia Prepaid.

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. 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. An evaluation of the remaining useful lives of the definite-lived intangible assets is performed periodically to determine if any change is warranted.

Impairment of Long-lived Assets

Impairment and Disposals of Long-lived 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. If indicators exist, 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 (normally measured by the expected present value technique) is required. The Company recognized an expense of $8,903 during the year ended December 31, 2012. This expense is a consequence of the Company’s decision to utilize the software acquired with the acquisition of Fleet One, during the fourth quarter of 2012, as the processing platform for its over-the-road product. The Company also recognized approximately $600 in impairments and disposals of various other long-lived assets during the year ended December 31, 2012, some of which were related to the Fleet One acquisition. The Company did not recognize any significant impairment expense on the Company’s long-lived assets during the years ended December 31, 2013 and 2011. Write-offs due to the acquisition of Fleet One were recorded in depreciation, amortization and impairments in the consolidated statements of income. Disposals over the ordinary course of business are recorded in occupancy and equipment in the consolidated statements of income.

Other Assets

Other Assets

The Company has an investment in the stock of the Federal Home Loan Bank totaling $1,479 for the year ended December 31, 2013, $1,534 for the year ended December 31, 2012 and $1,562 for the year ended December 31, 2011. The investment is carried at cost and not considered a readily marketable security. This investment is included in other assets on the consolidated balance sheets. As of December 31, 2013, the Company has concluded that the investment is not impaired.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

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, borrowed federal funds and credit agreement borrowings approximate their respective fair values as the interest rates on these financial instruments are variable. All other financial instruments are reflected at fair value on the consolidated balance sheet.

Revenue Recognition

Revenue Recognition

The majority of the Company’s revenues are comprised of transaction-based fees, which generally are 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 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.

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

Payment Processing Revenue.    Revenue consists of transaction fees assessed to major oil companies, fuel retailers and vehicle maintenance providers. 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. 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.

Interchange income is earned by the Company’s corporate purchase card and payroll card products and is included in payment processing revenue. 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 payment processing revenue, the Company is generally responsible for the collection of the total transaction amount 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 wholesale 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.

Transaction Processing Revenue.    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.

Account Servicing Revenue.    Revenue is primarily comprised of monthly fees based on vehicles serviced. These fees are primarily in return for providing monthly vehicle data reports. Account servicing revenue is recognized monthly, as the Company fulfills its contractual service obligations. The Company also recognizes service fees related to rapid! PayCard services for card fees charged to the cardholder.

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 the entire balance outstanding from the customer. On occasion, these fees are waived. The Company’s established reserve for such waived amounts is estimated and offset against the late fee revenue recognized. These waived fees amounted to $4,557 in 2013 and $3,905 in 2012. The Company’s subsidiary, Fleet One, 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 interest earned on the Company’s foreign paycard product.

Other.    The Company assesses fees for providing ancillary services, such as information products and services, 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. 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. In addition, the Company sells assorted equipment to its Pacific Pride franchisees. 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.

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.

Stock-Based Compensation

Stock-Based Compensation

The Company recognizes the fair value of all stock-based payments to employees in its financial statements. The Company measures stock-based compensation expense at the grant date, based on the estimated fair value of the award and uses the straight-line method of attribution, net of estimated forfeitures, for expensing awards over the employee requisite service period. The Company estimates the fair value of stock option awards using a Black-Scholes-Merton valuation model. 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 is recorded in salary and other personnel expense.

Advertising Costs

Advertising Costs

Advertising and marketing costs are expensed in the period the advertising activity occurs.

Income Taxes

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 realizability of deferred tax assets must also be assessed. 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 must be established for deferred tax assets which are not believed to more likely than not be realized in the future. Deferred taxes are not provided for the undistributed earnings of the Company’s foreign subsidiaries that are considered to be indefinitely reinvested outside of the United States.

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 Common Share

Earnings per Common Share

When diluted earnings per common share is calculated, weighted-average outstanding shares are adjusted for the dilutive effect of shares issuable upon the assumed conversion of the Company’s common stock equivalents, which consist of outstanding stock options and unvested restricted stock units. Holders of unvested restricted stock units are not entitled to participate in dividends, should they be declared.

Income available for common stockholders used to calculate earnings per share is as follows:

	Year ended December 31,
	2013		2012		2011
Net earnings attributable and available for common stockholders –Basic and Diluted	$	149,208	$	96,922	$	133,622

Weighted average common shares outstanding used to calculate earnings per share are as follows:

	Year ended December 31,
	2013	2012	2011
Weighted average common shares outstanding – Basic	38,946	38,840	38,686
Unvested restricted stock units	117	138	128
Stock options	40	114	184
Weighted average common shares outstanding – Diluted	39,103	39,092	38,998

Foreign Currency Movement

Foreign Currency Movement

The financial statements of the Company’s foreign subsidiaries, whose functional currencies are other than the U.S. dollar, are translated to U.S. dollars. Assets and liabilities are translated at the year-end spot exchange rate, revenue and expenses at average exchange rates and equity transactions at historical exchange rates. Exchange differences arising on translation are recorded as a component of accumulated other comprehensive income (loss).

Realized and unrealized gains and losses on foreign currency transactions are recorded directly in the consolidated statements of income except when such gains or losses result from intercompany transactions where repayment is not anticipated for the foreseeable future. In these situations, the gains or losses are deferred and included as a component of accumulated other comprehensive income (loss).

Accumulated Other Comprehensive Income (Loss)

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) includes unrealized gains and losses on available-for-sale securities, the changes in fair values of derivative instruments designated as hedges of future cash flows related to interest rate variability 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.

Recently Adopted Accounting Standards

Recently Adopted Accounting Standards

In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2013-11 Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11"). The amendments in ASU 2013-11 require entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss ("NOL") carryforward, a similar tax loss, or a tax credit carryforward except when the following exist: (i) an NOL carryforward, a similar tax loss, or a tax credit carryforward is not available as of the reporting date under the governing tax law to settle taxes that would result from the disallowance of the tax position, and (ii) the entity does not intend to use the deferred tax asset for this purpose (provided the tax law permits a choice). If any of these conditions exist, entities should present an unrecognized tax benefit in the financial statements as a liability and should not net the unrecognized tax benefit with a deferred tax asset. ASU 2013-11 is effective for interim and annual periods beginning after December 15, 2013. The Company does not believe that the adoption of ASU 2013-11 will have a material impact on its results of operations when adopted in 2014.

In February 2013, the FASB issued Accounting Standards Update No. 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This guidance is intended to provide disclosure on items reclassified out of accumulated other comprehensive income either in the notes or parenthetically on the face of the income statement. The required disclosure is in Note 18, Accumulated Other Comprehensive Income.

Tax Receivable Agreement

Income Tax Disclosure [Abstract]

Tax Receivable Agreement

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. The estimated total payments owed to Cendant Corporation based on facts available at that time, was reflected as a liability titled “Amounts due under tax receivable agreement.”

The amount of these estimated future payments 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. 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 income statement as changes in amounts due under tax receivable agreement.

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.

For each year presented, there had been reassessment of the blended tax rates that are projected into the future. The net future benefits increased, which increased the associated liability to Wyndham, resulting in a $33, $2,089 and $715 charge to non-operating expense for the years ended December 31, 2013, 2012 and 2011, respectively.

Fair Value Disclosures [Abstract]

Fair Value

Fair Value

The Company holds mortgage-backed and other asset-backed securities, fixed income and equity securities, derivatives and certain other financial instruments which 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. The Company carries certain of its liabilities at fair value, including its derivative liabilities. In determining the fair value of the Company’s obligations, various factors are considered including: closing exchange or over-the-counter market price quotations; time value and volatility factors underlying options and derivatives; price activity for equivalent instruments; the Company’s own-credit standing; and counterparty credit risk.

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.

The following table presents the Company’s assets and liabilities that are measured at fair value and the related hierarchy levels for 2013:

Available-for-sale securities and executive deferred compensation plan trust

When available, the Company uses quoted market prices to determine the fair value of available-for-sale securities; such items are classified in Level 1 of the fair-value hierarchy. These securities primarily consist of exchange-traded equity securities.

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 classified as Level 2. The obligations related to the deferred compensation plan trust are classified as Level 1 of the fair value hierarchy because the fair value is determined using quoted prices for identical instruments in active markets.

Fuel price derivatives

The majority of derivatives entered into by the Company are executed over-the-counter and are valued using internal valuation techniques as no quoted market prices exist for such instruments. The valuation technique and inputs depend on the type of derivative and the nature of the underlying instrument. The principal technique used to value these instruments is a comparison of the spot price of the underlying instrument to its related futures curve adjusted for the Company’s assumptions of volatility and present value, where appropriate. The fair values of derivative contracts reflect the expected cash the Company will pay or receive upon settlement of the respective contracts.

The key inputs depend upon the type of derivative and the nature of the underlying instrument and include interest rate yield curves, the spot price of the underlying instrument, volatility, and correlation. The item is placed in either Level 2 or Level 3 depending on the observability of the significant inputs to the model. Correlation and items with longer tenures are generally less observable.

Fuel price derivatives – diesel. The assumptions used in the valuation of the diesel fuel price derivatives use both observable and unobservable inputs. There is a lack of price transparency with respect to forward prices for diesel fuel. Such unobservable inputs are significant to the diesel fuel derivative contact valuation methodology.

Quantitative Information About Level 3 Fair Value Measurements. The significant unobservable inputs used in the fair value measurement of the Company’s diesel fuel price derivative instruments designated as Level 3 are as follows:

	Fair Value at December 31, 2013		Valuation Technique	Unobservable Input	Range $ per gallon
Fuel price derivatives – diesel	$	2,142	Option model	Future retail price of diesel fuel after December 31, 2013	3.71 – 3.94

Sensitivity To Changes In Significant Unobservable Inputs. As presented in the table above, the significant unobservable inputs used in the fair value measurement of the Company’s diesel fuel price derivative instruments are the future retail price of diesel fuel from the first quarter of 2014 through the second quarter of 2015. Significant changes in these unobservable inputs in isolation would result in a significant change in the fair value measurement.

Contingent consideration

The Company classified its liability for contingent consideration related to its acquisition of UNIK within Level 3 of the fair value hierarchy because the fair value was determined using significant unobservable inputs, which include the projected revenues of UNIK over a four month period. These assumptions included assessing the probability of meeting certain milestones required to earn the contingent consideration.

On June 30, 2013, the Company finalized the contingent consideration amount based on current performance milestones and determined it to be approximately $511, which was paid on July 1, 2013.

The Company classified its liability for contingent consideration related to its acquisition of rapid! PayCard within Level 3 of the fair value hierarchy because the fair value is determined using significant unobservable inputs, which include the projected revenues of rapid! PayCard over a twelve month period ending on March 31, 2012. On March 31, 2012, the amount due was determined to be $8,486 and was paid on April 30, 2012.

WEX Bank has issued certificates of deposit in various maturities ranging between 1 month and 2 years and with fixed interest rates ranging from 0.30 percent to 0.80 percent as of December 31, 2013. WEX Bank may issue certificates of deposit without limitation on the balance outstanding. WEX Bank must maintain minimum financial ratios, which include risk-based asset and capital requirements, as prescribed by the FDIC. As of December 31, 2013, certificates of deposit were in denominations of $250 or less.

The Company requires non-interest bearing deposits for certain customers as collateral for credit that has been extended.

The Company also had federal funds lines of credit totaling $125,000 at December 31, 2013 and $140,000 at December 31, 2012. There were no borrowings against these lines of credit at December 31, 2013 and $48,400 in outstanding borrowings against these lines of credit at December 31, 2012.

Interest-bearing money market deposits are issued in denominations of $250 or less, and pay interest at variable rates based on LIBOR or the Federal Funds rate. Money market deposits may be withdrawn by the holder at any time, although notification may be required and the monthly number of transactions is limited. As of December 31, 2013, the weighted average interest rate on interest-bearing money market deposits was 0.25 percent.

On January 11, 2012, the Company entered into an agreement with Higher One, Inc. (“Higher One”), a technology and payment services company focused on higher education, to offer negotiable order of withdrawal (“NOW”) accounts to a portion of Higher One’s customers. Higher One will provide processing and other administrative services while the Company, through its bank subsidiary WEX Bank, will establish and maintain the NOW accounts. During 2013 and the last three quarters of 2012, the Company received non-interest bearing NOW account deposits. As of December 31, 2013, the Company has $276,422 of non-interest bearing NOW account deposits outstanding.

Business Acquisitions and Other Intangible Assets Acquisitions

Business Acquisitions and Other Intangible Asset Acquisitions

Acquisition of FastCred

On October 15, 2013, the Company's Brazilian 51 percent majority-owned subsidiary UNIK S.A. (“UNIK”) acquired all of the stock of FastCred, a provider of fleet cards to the heavy truck or over-the-road segment of the fleet market, for approximately $12,309, net of cash acquired. The Company purchased FastCred to expand its Fleet Payment Solutions segment. During the fourth quarter of 2013, the Company allocated $4,282 of the cost of the acquisition to goodwill and $12,594 to other intangible assets, primarily customer relationships. The allocation of the purchase price is preliminary as the Company is still reviewing the intangible asset valuation. The total weighted average useful life of the intangible assets acquired from FastCred is 5 years. Goodwill recorded as a result of the FastCred acquisition is not currently deductible for income tax purposes. No pro forma information has been included in these financial statements as the operations of FastCred for the period that they were not part of the Company are not material to the Company’s revenues, net income and earnings per share.

Acquisition of CorporatePay

On May 11, 2012, the Company acquired all of the stock of CorporatePay, a provider of corporate prepaid solutions to the travel industry in the United Kingdom for approximately $27,800, net of cash acquired. The Company purchased CorporatePay to expand its Other Payment Solution segment. During the second quarter of 2012, the Company allocated the purchase price of the acquisition based upon a preliminary estimate of the fair values of the assets acquired and liabilities assumed. During the first quarter of 2013, the Company obtained information to assist in determining the fair values of certain tangible and intangible assets acquired and liabilities assumed as of the CorporatePay acquisition date. Based on such information, the Company retrospectively adjusted the fiscal year 2012 comparative information resulting in an increase in accounts receivable of $508, a decrease in deferred taxes of $32, an increase in intangible assets of $140, a decrease in goodwill of $247, and an increase in accrued expenses of $369. There were no changes to the previously reported consolidated statements of operations or statements of cash flows. With the initial purchase of CorporatePay, the Company established a full valuation allowance of $1,219 on the acquired net operating losses. The Company believes it is more likely than not that the losses will not be utilized. The valuations of all assets and liabilities have been finalized.

Goodwill related to the CorporatePay acquisition is not expected to be deductible for income tax purposes. The results of operations of CorporatePay are reflected in the Other Payment Solutions segment from the date of acquisition.

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

Consideration paid (net of cash)	$	27,783
Less:
Accounts receivable	1,585
Accounts payable	(629		)
Other tangible liabilities, net	(4,040		)

^(a)  Weighted average life – 6.2 years.

^(b)  Weighted average life – 6.3 years.

^(c)  Weighted average life – 5.3 years.

No pro forma information has been included in these financial statements as the operations of CorporatePay for the period that they were not part of the Company are not material to the Company’s revenues, net income and earnings per share.

Acquisition of UNIK

On August 30, 2012, the Company acquired a 51 percent ownership interest in UNIK, a privately-held provider of payroll cards in Brazil. The Company purchased its interest in UNIK to expand its Other Payment Solutions segment. UNIK is a provider of payroll cards, private label and processing services in Brazil specializing in the retail, government and transportation sectors.

The investment was consummated through the purchase of newly issued shares of UNIK for approximately $22,800. The purchase agreement also included a potential contingent consideration component based on performance milestones. Although the contingent consideration was not capped, the Company estimated the amount of the liability, at the time of acquisition, to be approximately $991 at the time of acquisition. On December 31, 2012, the Company revised the estimate based on current performance milestones to be approximately $313. On June 30, 2013, the Company finalized the contingent consideration amount based on current performance milestones and determined it to be approximately $511, which was paid on July 1, 2013. The purchase agreement further provides the Company with a call option which allows the Company to acquire the remaining shares at specific times over a three-year period. Additionally the agreement provides the noncontrolling shares with the right to put their interest back to the Company at specific times. The put options are exercisable at specific dates subject to the achievement of performance hurdles. Pricing for both the call and put options are based upon multiples of UNIK’s trailing twelve month EBITDA. Using the proceeds from the acquisition of UNIK, UNIK paid down approximately $19,600 of existing financing debt. As of December 31, 2013, UNIK has approximately $7,278 of financing debt, classified in other liabilities on the Company’s consolidated balance sheets.

Based on its ownership position, the Company concluded that it has acquired a controlling interest in UNIK. During the third quarter of 2012, the Company allocated the purchase price of the acquisition based upon a preliminary estimate of the fair values of the assets acquired and liabilities assumed. Goodwill associated with the transaction is not expected to be deductible for income tax purposes. In addition, the Company has recognized and measured a redeemable noncontrolling interest. The redeemable noncontrolling interest represents the portion of UNIK’s net assets owned by the noncontrolling shareholders and is presented in the mezzanine section on the Company’s consolidated balance sheets. The results of operations of UNIK are reflected in the Other Payment Solutions segment. During the third quarter of 2013, the Company obtained information to assist in determining the fair values of certain tangible and intangible assets acquired and liabilities assumed as of the UNIK acquisition date. Based on such information, the Company retrospectively adjusted the fiscal year 2012 comparative information resulting in an increase in deferred taxes of $2,243, an increase in goodwill of $4,355, and an increase in accrued expenses of $6,598. There were no changes to the previously reported consolidated statements of operations or statements of cash flows. The valuations of all assets and liabilities have been finalized.

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

Total UNIK value	$	44,701
Less: Redeemable noncontrolling interest	21,904
Total purchase price (includes estimated earn out of $991)	$	22,797

No pro forma information has been included in these financial statements as the operations of UNIK for the period that they were not part of the Company are not material to the Company’s revenues, net income and earnings per share.

Acquisition of Fleet One

On October 4, 2012, the Company acquired certain assets of Fleet One, a privately-held provider of value-based business payment processing and information management solutions. The Company purchased Fleet One to expand its fuel card and fleet management information services, as well as to accelerate its presence in the over-the-road market.

Fleet One was purchased from the private equity firms of LLR Partners and FTV Capital for approximately $376,258, net of cash acquired. During the fourth quarter of 2012, the Company allocated the purchase price of the acquisition based upon a preliminary estimate of the fair values of the assets acquired and liabilities assumed. During the third quarter of 2013, the Company obtained information to assist in determining the fair values of certain tangible and intangible assets acquired and liabilities assumed as of the Fleet One acquisition date. Based on such information, the Company retrospectively adjusted the fiscal year 2012 comparative information resulting in a decrease in accounts receivable of $47, an increase in deferred taxes of $261, a decrease in goodwill of $407, a decrease in taxes payable of $113 and a decrease in accrued expenses of $80. There were no changes to the previously reported consolidated statements of operations or statements of cash flows. The valuations of all assets and liabilities have been finalized.

The operations at Fleet One contributed net revenues of approximately $14,200 and net earnings of approximately $1,400 from October 4, 2012, through December 31, 2012. The goodwill is expected to be deductible for tax purposes. Operations from Fleet One are reflected in the Fleet Payment Solutions segment from the date of acquisition.

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

Consideration paid (net of cash)	$	376,258
Less:
Accounts receivable	152,527

Acquisition of rapid! Financial Services LLC

On March 31, 2011, the Company acquired certain assets of rapid! Financial Services LLC (“rapid! PayCard”) for approximately $18,000 including an estimate of contingent consideration for future performance milestones of $10,000. rapid! PayCard is a provider of payroll prepaid cards, e-paystubs and e-W2s, and is focused on small and medium sized businesses. The Company purchased rapid! PayCard to expand its Other Payment Solutions segment. During the first quarter of 2011, the Company allocated the purchase price of the acquisition based upon a preliminary estimate of the fair values of the assets acquired and liabilities assumed. During the first quarter of 2012, the Company finalized the valuation of the intangible assets associated with the trade name. The goodwill is expected to be deductible for tax purposes.

A contingent consideration agreement was entered into in connection with the purchase of rapid! PayCard. Under the terms of the agreement the former owners of rapid! PayCard were entitled to receive additional consideration based upon the achievement of certain performance criteria, measured over the twelve-month period from the date of purchase. During the fourth quarter of 2011, the Company revised the estimate of contingent consideration to approximately $9,325. The resulting impact of this adjustment ($675) was an offset to other operating expense in our Other Payment Solutions segment. During the second quarter of 2012, the Company lowered the estimate to $8,486 and settled the contingent consideration.

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

In general, the terms of the Company’s trade receivables provide for payment terms of 30 days or less. The Company does not extend revolving credit to its customers with respect to these receivables. The portfolio of receivables is considered to be a large group of smaller balance homogeneous amounts that are collectively evaluated for impairment.

At December 31, 2013, approximately 95 percent of the outstanding balance of total trade accounts receivable was current and approximately 99 percent of the outstanding balance of total trade accounts receivable was less than 60 days past due. At December 31, 2012, approximately 96 percent of the outstanding balance of total trade accounts receivable was current and approximately 99 percent of the outstanding balance was less than 60 days past due.The outstanding balance is made up of receivables from a wide range of industries. No customer makes up more than 4 percent of the outstanding receivables at December 31, 2013.

The following table presents changes in reserves for credit losses related to accounts receivable:

The Company’s management has determined that the gross unrealized losses on its investment securities at December 31, 2013 and 2012 are temporary in nature. The Company reviews its investments to identify and evaluate investments that have indications of possible impairment. The Company’s techniques used to measure the fair value of its investments are in Note 15, Fair Value. Factors considered in determining whether a loss is temporary include the length of time and extent to which 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 Company had maturities of available-for-sale securities of $1,192 for the year ended December 31, 2013, $1,551 for the year ended December 31, 2012, and $841 for the year ended December 31, 2011.

(a)     The prior years amounts have been adjusted to reflect changes as a result of finalizing the purchase accounting.

The Company adjusted the consolidated balance sheet amount for goodwill and intangible assets at December 31, 2012, and December 31, 2011, to account for the measurement period adjustments related to the CorporatePay, UNIK, Fleet One and rapid! PayCard purchase price allocations.

During the third quarter of 2012, the Company determined that pricing pressure in the prepaid giftcard product in Australia would result in lower future earnings than forecasted at the time of the purchase of WEX Prepaid Cards Australia. On September 30, 2012, the Company recorded an estimated goodwill impairment loss of $16,171 related to the purchase of WEX Prepaid Cards Australia. The Company used a discounted cash flow model of the projected earnings of Wright Express Prepaid Australia, which is a level 3 fair value measurement, to determine the amount of goodwill impairment. This amount was finalized during the fourth quarter of 2012. During the fourth quarter of 2012, the Company recorded a goodwill impairment loss of $1,337, which is a level 3 fair value measurement, related to the purchase of Financial Automation Limited, acquired in August of 2008.

The changes in intangible assets during the period January 1 to December 31, 2013, were as follows: 

	Net Carrying Amount, Beginning of Period (a)		Acquisition		Transfer from indefinite-lived intangible assets to definite-lived intangible assets			Amortization		Impacts of Foreign Currency Translation		Net Carrying Amount, End of Period

(a)     The prior years amounts have been adjusted to reflect changes as a result of finalizing the purchase accounting.

During the third quarter of 2013, the Company determined that the intangible asset recorded for the trade name associated with Wright Express Corporation should be reclassified from an indefinite-lived intangible asset to a definite-lived intangible asset due to the current re-branding efforts of changing from the Wright Express brand to the WEX brand initiated domestically and abroad. The Company determined that a 10 year life would be appropriate in conjunction with the re-branding strategy initiated during the third quarter of this year.

The changes in intangible assets during the period January 1 to December 31, 2012, were as follows:

	Net Carrying Amount, Beginning of Period		Acquisition (a)		Amortization			Impacts of Foreign Currency Translation			Net Carrying Amount, End of Period

Total	$	74,672		$	102,600

The deferred tax assets and deferred tax liabilities are included in deferred income taxes, net on the consolidated balance sheet where a right of offset exists.

The Company’s primary tax jurisdictions are the United States and Australia. The Company had approximately $561,469 of state and $31,489 of foreign net operating loss carry forwards at December 31, 2013 and approximately $462,396 of state and $22,183 of foreign net operating loss carry forwards at December 31, 2012. These U.S. losses expire at various times through 2033. Foreign losses in Brazil and the U.K. have indefinite carry forward periods. The Company has established a valuation allowance primarily for acquired net operating losses in the UK for which the Company has determined it is more likely than not that the losses will not be utilized. No valuation allowances have been established for all other deferred assets as the Company believes it is more likely than not that its deferred tax assets will be utilized within the carry forward periods.

Undistributed earnings of certain foreign subsidiaries of the Company amounted to $4,665 at December 31, 2013, and $1,756 at December 31, 2012. These earnings are considered to be indefinitely reinvested, and accordingly, no U.S. federal and state income taxes have been provided thereon. Upon distribution of these earnings in the form of dividends or otherwise, the Company would be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and withholding taxes payable to the various foreign countries. The Company has determined that the amount of taxes attributable to these undistributed earnings is not practicably determinable.

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.

The Company files a consolidated federal income tax return in the United States, as well as consolidated or separate income tax returns in most states. The Company also files consolidated or separate income tax returns in non-U.S. jurisdictions where required. In the normal course of business, the Company is no longer subject to income tax examination for the years prior to 2010.

A reconciliation of the beginning and ending amount of unrecognized tax benefits excluding interest and penalties is as follows:

	Year ended December 31,
	2013			2012		2011
Beginning balance	$	6,176		$	6,059	$	—
Increases related to prior year tax position	—			—		6,059
(Decreases) increases related to prior year tax positions, due to foreign currency exchange	(893		)	117		—
Ending balance	$	5,283		$	6,176	$	6,059

At December 31, 2013, the Company had $6,908 of net unrecognized tax benefits. If recognized, $6,908 would reduce the Company’s effective tax rate. The Company does not anticipate settling any unrecognized tax benefit within the next 12 months.

The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The Company has accrued $1,625 as of December 31, 2013, $1,313 as of December 31, 2012 and $500 as of December 31, 2011, for penalties and interest related to uncertain tax positions.

On June 29, 2012, tax legislation was enacted in Australia that affected the tax deductibility of certain intangible assets acquired as part of the 2010 acquisition of Wright Express Australia. The Company performed a review of the legislation to determine which of these intangible assets would be impacted. Based upon this review the Company recorded a tax charge of $31,432 in June of 2012 to reflect these impacts. The Company wrote-off an associated refund claim payable to the former shareholder of RD Card Holding Australia for $9,750, included in non-operating income. This payable was contingent on the receipt of the tax refunds generated by tax deductions associated with the amortization of above mentioned intangible assets.

During 2012, the Company recorded an impairment charge related to goodwill in the amount of $17,508. This charge did not result in any tax provision benefit. The Company also recorded a tax charge of approximately $2,400 due to the impact of a retroactive tax legislation enacted on September 8, 2012 in Australia. This legislation impacted the potential deductibility of intercompany interest expense allowable in past and future tax years and hence resulted in a discrete charge in our recorded tax expense in the current year and a higher Australian effective tax rate in future periods.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Business Description

WEX Inc. (“Company”) is a provider of corporate card payment solutions. The Company provides products and services that meet the needs of businesses in various geographic regions including North and South America, Asia Pacific and Europe. The Company’s Fleet Payment Solutions and Other Payment Solutions segments provide its customers with security and control for complex payments across a wide spectrum of business sectors. The Company markets its products and services directly, as well as through strategic relationships which include major oil companies, fuel retailers and vehicle maintenance providers.

Basis of Presentation

The accompanying consolidated financial statements of WEX Inc. for the years ended December 31, 2013, 2012 and 2011, include the accounts of WEX Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

The Company adjusted the consolidated balance sheet amounts as of December 31, 2012, to account for the measurement period adjustments related to the CorporatePay, UNIK and Fleet One purchase price allocations discussed in Note 3, Business Acquisitions, and Other Intangible Asset Acquisitions below. The Company adjusted the statement of stockholders' equity amounts as of December 31, 2010, and for the years ended December 31, 2011 and 2012, to present treasury shares purchased and deferred stock units vested. The Company adjusted the statements of cash flow for the years ended December 31, 2011 and 2012, to combine acquisitions and investments into one single line item presentation.

The presentation of the Company’s consolidated balance sheet as of December 31, 2012 has been corrected for an immaterial error in the classification of foreign deferred tax liabilities. As of December 31, 2012, the foreign jurisdiction deferred tax liability balance was erroneously netted with the domestic deferred tax asset balance and presented on the consolidated balance sheet as a deferred tax asset. This correction of the error resulted in an increase in deferred tax assets and total assets of $18,407 and a corresponding increase in deferred tax liabilities, total liabilities, and total liabilities and stockholders’ equity of $18,407. The result of this correction did not impact the Company’s consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for any period presented.

Use of Estimates and Assumptions

The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. 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 market value. Cash equivalents include federal funds sold, which are unsecured short-term investments entered into with financial institutions.

Accounts Receivable and Reserve for Credit Losses

Accounts receivable balances are 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, 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.

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 sheet in accumulated other comprehensive income (loss). Realized gains and losses and declines in fair value determined to be other-than-temporary on available-for-sale securities are included in non-operating revenues and 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 revenues. 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

The Company uses derivative instruments as part of its overall strategy to manage its exposure to fluctuations in fuel prices and to reduce the impact of interest rate volatility. All derivatives are recorded at fair value on the consolidated balance sheet.

The Company’s fuel price derivative instruments do not qualify for hedge accounting treatment; therefore, gains or losses related to fuel price derivative instruments, both realized and unrealized, are recognized in earnings. These instruments are presented on the consolidated balance sheet as fuel price derivatives, at fair value. For the purposes of cash flow presentation, realized gains or losses are included in operating cash flows, as they are intended to hedge operating cash flows.

In prior years, the Company used interest rate derivatives designated as cash flow hedges and, accordingly, the change in fair value associated with the effective portion of these derivative instruments that qualified for hedge accounting treatment was recorded as a component of other comprehensive income (loss) and the ineffective portion, if any, was reported in earnings. Amounts included in other comprehensive income (loss) were reclassified into earnings in the same period during which the hedged item affected earnings. These instruments were presented as either other assets or accrued expenses on the consolidated balance sheet.

The Company assessed the hedge effectiveness of the interest rate swaps in accordance with the requirements outlined in the accounting standards. For these hedges, management documented, both at inception and over the life of the hedge, at least quarterly, its analysis of actual and expected hedge effectiveness. For those hedging relationships in which the critical terms of the entire debt instrument and the derivative were identical, and the creditworthiness of the counterparty to the hedging instrument remained sound, there was no hedge ineffectiveness as long as those conditions continue to be met. As of December 31, 2013, the Company does not have any interest rate swaps outstanding.

Property and Equipment

Property and equipment are stated at cost less 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. Leasehold improvements are primarily depreciated using the straight-line method over the lesser of the useful life of the asset or over the remaining lease term.

Below is the estimated useful lives for assets placed in service during 2013 and beyond:

	Estimated Useful Lives
Furniture, fixtures and equipment	3 to 5 years
Computer software	18 months to 7 years
Leasehold improvements	up to 5 years

Capitalized Software

The Company develops software that is used in providing 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. Software development costs are capitalized beginning when technological feasibility of the software has been established. Costs incurred prior to establishing technological feasibility are expensed as incurred. Technological feasibility is established when the Company has completed all planning, designing, coding and testing activities that are necessary to determine that the software can be produced to meet its design specifications, including functions, features and technical performance requirements. Capitalization of costs ceases when the software is ready for its intended use. 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:

	Year ended December 31,
	2013		2012		2011
Amounts capitalized for internal-use computer software	$	18,360	$	17,341	$	17,463
Amounts expensed for amortization of internal-use computer software	18,830		20,694		18,690

Goodwill and Other Intangible Assets

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 would record 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.

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 a variety of methodologies to estimate fair value, but primarily relies on discounted cash flow analyses. 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 fair value. Impairment charges are recorded in depreciation, amortization and impairment expense on the consolidated statements of income. The Company's annual goodwill and intangible asset impairment tests performed as of October 1, 2013 did not identify any impairment. The Company’s annual goodwill and intangible assets impairment tests, performed as of October 1, 2012, identified an impairment of $1,337 of goodwill associated with the acquisition of Financial Automation Limited, acquired in August of 2008. On September 30, 2012, the Company impaired $16,171 of goodwill associated with Wright Express Australia Prepaid.

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. 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. 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 Long-lived 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. If indicators exist, 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 (normally measured by the expected present value technique) is required. The Company recognized an expense of $8,903 during the year ended December 31, 2012. This expense is a consequence of the Company’s decision to utilize the software acquired with the acquisition of Fleet One, during the fourth quarter of 2012, as the processing platform for its over-the-road product. The Company also recognized approximately $600 in impairments and disposals of various other long-lived assets during the year ended December 31, 2012, some of which were related to the Fleet One acquisition. The Company did not recognize any significant impairment expense on the Company’s long-lived assets during the years ended December 31, 2013 and 2011. Write-offs due to the acquisition of Fleet One were recorded in depreciation, amortization and impairments in the consolidated statements of income. Disposals over the ordinary course of business are recorded in occupancy and equipment in the consolidated statements of income.

Other Assets

The Company has an investment in the stock of the Federal Home Loan Bank totaling $1,479 for the year ended December 31, 2013, $1,534 for the year ended December 31, 2012 and $1,562 for the year ended December 31, 2011. The investment is carried at cost and not considered a readily marketable security. This investment is included in other assets on the consolidated balance sheets. As of December 31, 2013, the Company has concluded that the investment is not impaired.

Fair Value of Financial Instruments

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, borrowed federal funds and credit agreement borrowings approximate their respective fair values as the interest rates on these financial instruments are variable. All other financial instruments are reflected at fair value on the consolidated balance sheet.

Revenue Recognition

The majority of the Company’s revenues are comprised of transaction-based fees, which generally are 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 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.

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

Payment Processing Revenue.    Revenue consists of transaction fees assessed to major oil companies, fuel retailers and vehicle maintenance providers. 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. 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.

Interchange income is earned by the Company’s corporate purchase card and payroll card products and is included in payment processing revenue. 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 payment processing revenue, the Company is generally responsible for the collection of the total transaction amount 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 wholesale 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.

Transaction Processing Revenue.    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.

Account Servicing Revenue.    Revenue is primarily comprised of monthly fees based on vehicles serviced. These fees are primarily in return for providing monthly vehicle data reports. Account servicing revenue is recognized monthly, as the Company fulfills its contractual service obligations. The Company also recognizes service fees related to rapid! PayCard services for card fees charged to the cardholder.

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 the entire balance outstanding from the customer. On occasion, these fees are waived. The Company’s established reserve for such waived amounts is estimated and offset against the late fee revenue recognized. These waived fees amounted to $4,557 in 2013 and $3,905 in 2012. The Company’s subsidiary, Fleet One, 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 interest earned on the Company’s foreign paycard product.

Other.    The Company assesses fees for providing ancillary services, such as information products and services, 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. 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. In addition, the Company sells assorted equipment to its Pacific Pride franchisees. 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.

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.

Stock-Based Compensation

The Company recognizes the fair value of all stock-based payments to employees in its financial statements. The Company measures stock-based compensation expense at the grant date, based on the estimated fair value of the award and uses the straight-line method of attribution, net of estimated forfeitures, for expensing awards over the employee requisite service period. The Company estimates the fair value of stock option awards using a Black-Scholes-Merton valuation model. 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 is recorded in salary and other personnel expense.

Advertising Costs

Advertising and marketing costs are expensed in the period the advertising activity occurs.

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 realizability of deferred tax assets must also be assessed. 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 must be established for deferred tax assets which are not believed to more likely than not be realized in the future. Deferred taxes are not provided for the undistributed earnings of the Company’s foreign subsidiaries that are considered to be indefinitely reinvested outside of the United States.

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 Common Share

When diluted earnings per common share is calculated, weighted-average outstanding shares are adjusted for the dilutive effect of shares issuable upon the assumed conversion of the Company’s common stock equivalents, which consist of outstanding stock options and unvested restricted stock units. Holders of unvested restricted stock units are not entitled to participate in dividends, should they be declared.

Income available for common stockholders used to calculate earnings per share is as follows:

	Year ended December 31,
	2013		2012		2011
Net earnings attributable and available for common stockholders –Basic and Diluted	$	149,208	$	96,922	$	133,622

Weighted average common shares outstanding used to calculate earnings per share are as follows:

	Year ended December 31,
	2013	2012	2011
Weighted average common shares outstanding – Basic	38,946	38,840	38,686
Unvested restricted stock units	117	138	128
Stock options	40	114	184
Weighted average common shares outstanding – Diluted	39,103	39,092	38,998

Foreign Currency Movement

The financial statements of the Company’s foreign subsidiaries, whose functional currencies are other than the U.S. dollar, are translated to U.S. dollars. Assets and liabilities are translated at the year-end spot exchange rate, revenue and expenses at average exchange rates and equity transactions at historical exchange rates. Exchange differences arising on translation are recorded as a component of accumulated other comprehensive income (loss).

Realized and unrealized gains and losses on foreign currency transactions are recorded directly in the consolidated statements of income except when such gains or losses result from intercompany transactions where repayment is not anticipated for the foreseeable future. In these situations, the gains or losses are deferred and included as a component of accumulated other comprehensive income (loss).

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) includes unrealized gains and losses on available-for-sale securities, the changes in fair values of derivative instruments designated as hedges of future cash flows related to interest rate variability 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.

Recently Adopted Accounting Standards

In July 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2013-11 Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (“ASU 2013-11"). The amendments in ASU 2013-11 require entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for a net operating loss ("NOL") carryforward, a similar tax loss, or a tax credit carryforward except when the following exist: (i) an NOL carryforward, a similar tax loss, or a tax credit carryforward is not available as of the reporting date under the governing tax law to settle taxes that would result from the disallowance of the tax position, and (ii) the entity does not intend to use the deferred tax asset for this purpose (provided the tax law permits a choice). If any of these conditions exist, entities should present an unrecognized tax benefit in the financial statements as a liability and should not net the unrecognized tax benefit with a deferred tax asset. ASU 2013-11 is effective for interim and annual periods beginning after December 15, 2013. The Company does not believe that the adoption of ASU 2013-11 will have a material impact on its results of operations when adopted in 2014.

In February 2013, the FASB issued Accounting Standards Update No. 2013-02 Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This guidance is intended to provide disclosure on items reclassified out of accumulated other comprehensive income either in the notes or parenthetically on the face of the income statement. The required disclosure is in Note 18, Accumulated Other Comprehensive Income.

2007 Revolving Credit Facility and 2010 Term Loan Note

On May 22, 2007, the Company entered into a revolving credit facility (the “2007 Revolver”) with a lending syndicate. The 2007 Revolver initially provided for a five-year $350,000 unsecured revolving line of credit. In connection with the 2007 Revolver, the Company paid loan origination fees of $998. These fees were recorded as other assets on the consolidated balance sheet and were amortized on a straight-line basis (which approximates the effective interest rate method) over the term of the 2007 Revolver. On May 29, 2008, the Company entered into an incremental amendment agreement (the “Incremental Amendment Agreement”) of the 2007 Revolver to increase the aggregate unsecured revolving line-of-credit from $350,000 to $450,000. The Company incurred $1,556 in loan origination fees in conjunction with entering into the Incremental Amendment Agreement. These fees have been recorded as other assets on the consolidated balance sheet and were amortized over the remaining term of the 2007 Revolver.

On July 25, 2010, the Company entered into a $75,000 term credit facility (“2010 term loan”). The rate on the 2010 term loan was 250 basis points above LIBOR. In connection with the 2010 term loan, the Company paid loan origination fees of $2,269. The agreement did not change any of the Company’s existing financial covenants.

The 2007 Revolver and the 2010 term loan were refinanced in 2011 as described below.

2011 Credit Agreement

On May 23, 2011, the Company entered into a credit agreement (the “2011 Credit Agreement”), by and among the Company and certain of its subsidiaries, as borrowers, and Wright Express Card Holdings Australia Pty Ltd, as specified designated borrower, with a lending syndicate. The 2011 Credit Agreement was secured by pledges of the stock of the Company’s foreign subsidiaries. The 2011 Credit Agreement provided for a five-year $200,000 amortizing term loan facility and a five-year $700,000 revolving credit facility with a $100,000 sub-limit for letters of credit. Term loan payments in the amount of $2,500 per quarter began on June 30, 2011, and were scheduled to continue on the last day of each September, December, March and June thereafter, through and including March 31, 2016. On the maturity date for the term agreement, May 23, 2016, the remaining outstanding principal amount of $150,000 would have been due.

As of December 31, 2012, the Company had $621,000 of loans outstanding under the 2011 Credit Agreement (including $182,500 under the term loan and $438,500 under the revolving credit facility). As of December 31, 2012, the Company had posted approximately $2,350 letters of credit as collateral for fuel derivatives and lease agreements. Accordingly, at December 31, 2012, the Company had $264,150 of availability under the 2011 Credit Agreement, subject to the covenants as described below. The Company capitalized approximately $6,200 in loan origination fees in association with this borrowing and wrote-off approximately $700 of previous issuance costs in the second quarter of 2011.

Proceeds from the 2011 Credit Agreement were used to refinance the Company’s existing indebtedness under its 2007 Revolver, and the existing indebtedness under the 2010 term loan. The 2011 Credit Agreement was available for working capital purposes, acquisitions, payment of dividends and other restricted payments, refinancing of indebtedness, and other general corporate purposes.

Amounts outstanding under the 2011 Credit Agreement bears interest at a rate equal to, at the Company’s option, (a) the Eurocurrency Rate, as defined, plus a margin of 1.25 percent to 2.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the highest of (i) the Federal Funds Rate plus 0.50 percent, (ii) the prime rate announced by lead lender, or (iii) the Eurocurrency Rate plus 1.00 percent, in each case plus a margin of 0.25 percent to 1.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA. In addition, the Company agreed to pay a quarterly commitment fee at a rate per annum ranging from 0.20 percent to 0.40 percent of the daily unused portion of the credit facility. Any outstanding loans under the 2011 Credit Agreement would have matured on May 23, 2016.

The 2011 Credit Agreement was replaced in January of 2013 by an Amended and Restated Credit Agreement (the “2013 Credit Agreement”).

2013 Credit Agreement and $400 Million Notes Outstanding

On January 18, 2013, the Company entered into the 2013 Credit Agreement, among the Company, as borrower, Wright Express Card Holdings Australia Pty Ltd, a wholly-owned subsidiary of the Company, as specified designated borrower (“Card Holdings Australia”, and, together with the Company, the “Borrowers”), Bank of America, N.A., as administrative agent and letter of credit issuer (“Bank of America”), and the other lenders party thereto (the “Lenders”). The 2013 Credit Agreement provides for a five-year $300,000 term loan facility, and a five-year $800,000 secured revolving credit facility with a $150,000 sub-limit for letters of credit. The indebtedness covenant under the 2013 Credit Agreement requires that the Company reduce the revolving commitments under the 2013 Credit Agreement on a dollar-for-dollar basis to the extent that the Company issues more than $300,000 in principal amount of senior or senior subordinated notes of the Company. Subject to certain conditions, including obtaining relevant commitments, the Company has the option to increase the facility by up to an additional $100,000.

The 2013 Credit Agreement amends, restates and substitutes for the 2011 Credit Agreement, among the Company, Card Holdings Australia, Bank of America, as administrative agent, the joint lead arrangers and other agents named therein, and a syndicate of lenders. The 2013 Credit Agreement increases the outstanding amount of the term loan from $185,000 to $300,000 and increases the amount of the revolving loan from $700,000 to $800,000. A portion of the indebtedness owing under the 2013 Credit Agreement is the same indebtedness as formerly evidenced by the 2011 Credit Agreement.

Amounts outstanding under the 2013 Credit Agreement bore interest at a rate equal to, at the Company’s option, (a) the Eurocurrency Rate, as defined, plus a margin of 1.25 percent to 2.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the highest of (i) the Federal Funds Rate plus 0.50 percent, (ii) the prime rate announced by lead lender, and (iii) the Eurocurrency Rate plus 1.00 percent, in each case plus a margin of 0.25 percent to 1.25 percent based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA. In addition, the Company has agreed to pay a quarterly commitment fee at a rate per annum ranging from 0.20 percent to 0.40 percent of the daily unused portion of the credit facility. Any outstanding loans under the 2013 Credit Agreement mature in January of 2018, unless extended pursuant to the terms of the 2013 Credit Agreement.

On January 30, 2013, the Company, completed a $400,000 offering in 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 an indenture dated as of January 30, 2013 (the “Indenture”) among the Company, the guarantors listed therein, and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”).

The Notes will mature on February 1, 2023, and interest will accrue at the rate of 4.750 percent per annum. Interest is 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 unsecured 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 be subject to many of the restrictive covenants in the indenture governing the Notes.

The Notes and guarantees described above are general senior unsecured 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 junior in right of payment to all of the Company’s existing and future secured debt, including the Company’s 2013 Credit Agreement, to the extent of the value of the collateral securing such debt. 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 may redeem 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.

In addition, at any time prior to February 1, 2016, the Company may, subject to certain conditions, redeem up to 35 percent of the Notes from the proceeds of certain equity offerings at a redemption price of 104.75% percent of the principal amount, plus 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.

Under the terms of the 2013 Credit Agreement, the $800,000 secured revolving credit facility was reduced to $700,000 as a result of the $400,000 Notes offering.
