Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10–Q and Rule 10–01 of Regulation S–X. Accordingly, they do not include all information and notes required by GAAP for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the financial statements that are included in the Company’s Annual Report on Form 10–K for the year ended December 31, 2019, filed with the SEC on February 28, 2020. In the opinion of management, all adjustments considered necessary for a fair presentation, which are of a normal recurring nature, have been included. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results for any future periods or the year ending December 31, 2020. With the exception of accounting policies over credit loss reserves, which were impacted by the adoption of ASU 2016–13 effective January 1, 2020 (refer to Note 2, Recent Accounting Pronouncements), we have applied the same accounting policies in preparing these quarterly financial statements as we did in preparing our 2019 annual financial statements. The Company rounds amounts in the unaudited condensed consolidated financial statements to thousands and calculates all per-share data from underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot or recalculate based on reported numbers due to rounding. COVID-19 Pandemic Response and Impact A novel strain of coronavirus (COVID-19) was first identified in Wuhan, China in January 2020, and subsequently declared a global pandemic by the World Health Organization on March 11, 2020. During the first quarter of 2020, the Company took a number of precautionary steps to safeguard its business and employees from the effects of COVID-19 including implementing travel bans and restrictions, temporarily closing offices and canceling participation in various industry events. These precautionary steps have remained in force through the second quarter of 2020 as the Company continues to closely track and assess the rapidly evolving effect of the pandemic. The Company is actively managing its responses in collaboration with its employees, customers and suppliers. The spread of COVID-19, and conditions arising in connection with it, including government policies and stay-at-home orders, other restrictions on businesses and individuals and wider changes in business and customer behavior, have had a negative impact on the Company’s businesses during the three and six months ended June 30, 2020. The following describes these impacts by reportable segment: Fleet Solutions — Lower average domestic fuel prices and volumes have negatively impacted the Fleet Solutions segment compared to the prior year, primarily resulting from a decrease in demand in connection with the COVID-19 pandemic. Throughout the second quarter and into July, volumes worldwide have partly recovered from their April 2020 lows. Although the full extent of the COVID-19 pandemic and its future impact on Company operations is uncertain, we expect these trends and further stabilization to gradually continue into the third quarter. Travel and Corporate Solutions — The Travel and Corporate Solutions segment has been the most adversely impacted by the COVID-19 pandemic relative to our other segments, as the pandemic has resulted in a significant decline in worldwide travel and tourism. These disruptions are expected to have a continuing adverse impact on the Company’s operating results for the remainder of the year, although the full extent of the COVID-19 pandemic and its future impact on Company operations is uncertain. Health and Employee Benefit Solutions — Purchase volume for our U.S. Health business was challenged by the pandemic this quarter, down 26% as customers deferred non-essential medical treatments. Spend has trended upwards throughout the quarter and into July, and is now approximately flat with the prior year. Although the full extent of the COVID-19 pandemic and its future impact on the Company's operations is uncertain, we expect the trajectory of spend volumes that we saw in June and July to continue through the remainder of 2020, particularly as states reopen and customers begin to spend on elective healthcare procedures and resume a more normal cadence of doctor visits. In connection with these adverse impacts, the Company evaluated the impact of COVID-19 on its reporting units and asset groups and determined there was no impairment during the three or six months ended June 30, 2020. Adoption of a New Accounting Standard The Company adopted Topic 326 on January 1, 2020, utilizing the modified-retrospective approach, under which prior period comparable financial information was not adjusted. Topic 326 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables and off-balance sheet credit exposures. See Note 2, Recent Accounting Pronouncements, for further information regarding this new accounting standard. The following table illustrates the adoption impact of Topic 326: January 1, 2020 (In thousands) Prior to Adoption Impact of As Reported Allowance for accounts receivable 1 $ 52,274 $ 11,577 $ 63,851 Deferred income taxes, net (within total assets) $ 12,833 $ 570 $ 13,403 Deferred income taxes, net (within total liabilities) $ 218,740 $ (2,230) $ 216,510 Retained earnings $ 1,539,201 $ (8,587) $ 1,530,614 Non-controlling interest $ 9,575 $ (190) $ 9,385 1 This impact does not reflect the economic disruption resulting from the COVID-19 pandemic since it occurred subsequent to January 1, 2020. Allowance for Accounts Receivable The allowance for accounts receivable reflects management’s current estimate of uncollectible balances on its accounts receivable and consists primarily of reserves for credit losses. As a result of the adoption of Topic 326, the reserve for expected credit losses includes both a quantitative and qualitative reserve component. The quantitative component is primarily calculated using an analytic model, which includes the consideration of historical loss experience and past events to calculate actual loss-rates at the portfolio level. It also includes reserves against specific customer account balances determined to be at risk for non-collection based on customer information including delinquency, changes in payment patterns and other information. The qualitative component is determined through analyzing recent trends in economic indicators and other current and forecasted information to determine whether loss-rates are expected to change significantly in comparison to historical loss-rates at the portfolio level. When such indicators are forecasted to trend a predetermined amount from the historical median, the Company qualitatively determines what impact, if any, the trends are expected to have on the reserve for expected credit losses. Economic indicators include consumer price indexes, consumer spending and unemployment trends, among others. See Note 5, Accounts Receivable, for discussion regarding the adjustments made during the three and six months ended June 30, 2020 as a result of these assessments. Accounts receivable are evaluated for impairment on a pooling basis based on similar risk characteristics including industry of the borrower, historical or expected credit loss patterns, risk ratings or classification, and geographic location. As a result of this evaluation, our portfolio segments consist of the following: • Fleet Solutions - The majority of the customer base consists of companies within the transportation, logistics and fleet industries. The associated credit losses by customer are generally low, however, the Fleet Solutions segment has historically comprised the majority of the Company’s provision for credit loss. Credit losses generally correlate with changes in consumer price indices and other indices that measure trends and volatility including the Institute of Supply Management Purchasing Index and the U.S. Volatility Index. • Travel and Corporate Solutions - The customer base is comprised of businesses operating in a wide range of industries including large online travel agencies. With the exception of the Noventis portfolio, which has minimal credit risk due to its business model and collection terms, the associated credit losses are sporadic and closely correlate with trends in consumer metrics, including consumer spending and the consumer price index. • Health and Employee Benefit Solutions - The customer base includes third-party administrators, individual employers and employees. The associated credit losses are generally low. Prior to entering into the WEX Latin America accounts receivable securitization arrangement as described in Note 10, Off-Balance Sheet Arrangements, the Company maintained credit exposure on these receivables and accordingly established an allowance for credit losses, which is included in the Health and Employee Benefit Solutions balance as of June 30, 2020, as disclosed in Note 5, Accounts Receivable. When individual accounts receivable exhibit elevated credit risk characteristics as a result of bankruptcies, disputes, conversations with customers, or other significant credit loss events, they are assessed individual credit loss estimates. Assumptions regarding expected credit losses are reviewed each reporting period and may be impacted by actual performance of accounts receivable and changes in any of the factors discussed above. The allowance for accounts receivable also includes reserves for waived finance fees, which are used to maintain customer goodwill and recorded against the late fee revenue recognized, as well as reserves for fraud losses. Management monitors known and suspected fraudulent activity identified by the Company, as well as fraudulent claims reported by customers, in estimating the reserve for expected fraud losses. Off-Balance Sheet Arrangements The Company has various off-balance sheet commitments, certain of which carry credit risk exposure. These items were not significantly impacted by the adoption of Topic 326 as of June 30, 2020: • Extension of credit to customers - The Company has entered into commitments to extend credit in the ordinary course of business as part of established customer agreements. The unfunded portion of an extension of credit to customers fluctuates as the Company increases or decreases customer credit limits, subject to appropriate credit reviews. Given that the Company can generally adjust its customers’ credit lines at its discretion at any time, the unfunded portion of loan commitments to customers is unconditionally cancellable and thus the Company has not established a liability for expected credit losses on those commitments. • Accounts receivable factoring - See Note 10, Off-Balance Sheet Arrangements, for the terms of the factoring arrangements for the Company’s subsidiaries, WEX Europe Services and WEX Bank. Within the terms of the Company’s WEX Europe Services accounts receivable factoring arrangement, the Company has credit risk exposure to the extent outstanding transferred receivables exceed established credit limits. The Company does not maintain any beneficial interest with respect to the receivables sold, and as such does not maintain any credit risk related to receivables transferred below the established credit limit. The amount by which factored receivables exceed the credit limit is insignificant as of June 30, 2020. Management deems expected credit losses arising from this off-balance sheet commitment to be insignificant and did not establish a corresponding liability. The Company does not retain any beneficial interest in WEX Bank’s factored receivables, and the terms of the agreement do not describe a scenario in which the Company would be exposed to credit risk as it relates to the transferred receivables. • Accounts receivable securitization - See Note 10, Off-Balance Sheet Arrangements, for the terms of the securitization arrangement at one of the Company’s subsidiaries, WEX Latin America. Within the terms of the Company’s WEX Latin America accounts receivable securitization arrangement, the Company does not maintain credit exposure given that the Company has surrendered effective control and derecognized the receivables. The Company retains an interest in securitized receivables in the form of a non-controlling equity investment in the fund holding the receivables, in amounts of $4.7 million and $6.7 million as of June 30, 2020 and December 31, 2019, respectively. The Company’s beneficial interest in the securitized receivables carries residual credit risk, and the methodology for estimating expected credit losses on the beneficial interest is consistent with the methodology described within the Allowance for Accounts Receivable section above. As of both January 1, 2020 and June 30, 2020, expected credit losses estimated on the Company’s beneficial interest in WEX Latin America’s securitized receivables were insignificant.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	2. Recent Accounting Pronouncements The following table provides a brief description of accounting pronouncements adopted during the six months ended June 30, 2020 and recent accounting pronouncements not yet adopted that could have a material effect on our financial statements: Standard Description Date/Method of Adoption Effect on financial statements or other significant matters Adopted During the Six Months Ended June 30, 2020 ASU 2016–13 This standard amends the impairment model to utilize an expected loss methodology in place of the incurred loss methodology for financial instruments, including trade receivables and off-balance sheet credit exposures. The standard requires entities to consider a broader range of information to estimate expected credit losses, including historical experience, current conditions and reasonable and supportable forecasts that impact the collectability of the reported amount. The Company adopted ASU 2016–13 effective January 1, 2020 using the modified-retrospective approach. The amendments of this new standard were applied through a cumulative-effect adjustment to total stockholders’ equity of $8.8 million, net of a $2.8 million income tax benefit, as of January 1, 2020. This adjustment was driven by the incorporation of economic forecasts into the Company’s expected credit loss reserve methodology. The unaudited condensed consolidated financial statements for the three and six months ended June 30, 2020 are presented under the new standard. Comparative periods presented have not been adjusted. Refer to Note 1, Basis of Presentation, for discussion of the Company’s credit loss methodology. Not Adopted as of June 30, 2020 ASU 2020 – 04, Reference Rate Reform This standard provides optional guidance for a limited period of time to ease the potential financial reporting burden in accounting for (or recognizing the effects of) the discontinuation of LIBOR resulting from reference rate reform. The amendments provide optional expedients and exceptions for applying GAAP to contracts and other transactions impacted by reference rate reform. If certain criteria are met, an entity will not be required to remeasure or reassess contracts impacted by reference rate reform. Election is available through December 31, 2022. The Company is currently evaluating the implications of these amendments to its current efforts for reference rate reform implementation and any impact the adoption of this ASU would have on its financial condition and results of operations.

Business Combinations [Abstract]
Acquisitions	4. Acquisitions 2020 Purchase Agreement On January 24, 2020, the Company entered into a purchase agreement to purchase eNett and Optal for an aggregate purchase price comprised of approximately $1.3 billion in cash and 2.0 million shares of the Company’s common stock and subject to certain working capital and other adjustments as described in the purchase agreement. The parties’ obligations to consummate the acquisition are subject to customary closing conditions, including the absence of a Material Adverse Effect (as defined in the purchase agreement between WEX, eNett and Optal, among others) . The Company has analyzed the eNett and Optal situation closely with specialist advisors and has concluded that the COVID-19 pandemic and conditions arising in connection with it have had, and continue to have, a Material Adverse Effect on the businesses, which is disproportionate to the effect on others in the relevant industry. Because of this Material Adverse Effect, WEX formally advised eNett and Optal on May 4, 2020 that it is not required to close the transaction pursuant to the terms of the purchase agreement. On May 11, 2020, the shareholders of eNett and Optal each initiated separate legal proceedings against the Company denying that there has been a Material Adverse Effect and alleging that the Company has threatened to breach its obligations under the terms of the purchase agreement. The claimants seek a declaration that no Material Adverse Effect has occurred and orders for specific performance of WEX's obligations under the purchase agreement. A London court set September 21, 2020 as the starting date of a trial of certain preliminary issues. 2019 Business Acquisitions As of June 30, 2020, the purchase accounting was final for our 2019 business acquisitions. No adjustments to the purchase accounting were made during the three or six months ended June 30, 2020. In both the three and six months ended June 30, 2020, the acquisition and merger related costs related to the completed business combinations were immaterial. Acquisition-related costs on completed business combinations were $5.9 million and $9.0 million for the three and six months ended June 30, 2019. Go Fuel Card On July 1, 2019, the Company acquired Go Fuel Card, a European fuel card business, for a total purchase price of €235.0 million (equivalent of $266.0 million on date of purchase). This acquisition, which was funded with cash on hand, was accounted for as a business combination. The purpose of the acquisition was to strengthen the Company’s position in the European market, grow its existing customer base and reduce its sensitivity to retail fuel prices, resulting in the recording of goodwill. The goodwill associated with the acquisition of Go Fuel Card is deductible for tax purposes. The following is a summary of the final allocation of the purchase price to the assets and liabilities acquired, based on the fair value at the date of acquisition: (In thousands) Total consideration, net of $5,589 in cash acquired $ 260,455 Less: Network relationships (a) (d) 112,893 Customer relationships (b)(d) 33,963 Brand name (c) (d) 442 Deposits (5,169) Accrued expenses (420) Recorded goodwill $ 118,746 (a) Weighted average life - 10.1 years. (b) Weighted average life - 5.0 years. (c) Weighted average life - 1.0 year. (d) The weighted average life of all amortizable intangible assets acquired in this business combination is 8.9 years. No pro forma information has been disclosed in these financial statements as the operations of Go Fuel Card 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. Discovery Benefits, Inc. On March 5, 2019, the Company acquired Discovery Benefits, an employee benefits administrator, for a total purchase price of $526.1 million, of which $50 million was paid during the fourth quarter of 2019. The acquisition was primarily funded with cash on hand and through borrowings under the 2016 Credit Agreement. The seller of Discovery Benefits obtained a 4.9 percent equity interest in the newly formed parent company of WEX Health and Discovery Benefits, which constitutes the U.S. Health business. The fair value of the equity interest was determined to be $100.0 million on the acquisition date. See Note 13, Redeemable Non-Controlling Interest, for further information. The purpose of this acquisition was to obtain the comprehensive suite of products and services for the Company’s partners and customers and to open go-to-market channels to include consulting firms and brokers in its Health and Employee Benefit Solutions segment. This acquisition has been accounted for as a business combination, resulting in the recording of goodwill. The majority of the associated goodwill is deductible for tax purposes. The following is a summary of the final allocation of the purchase price to the assets and liabilities acquired, based on the fair value at the date of acquisition: (In thousands) Cash consideration, net of $125,865 in cash and restricted cash acquired $ 300,191 Fair value of redeemable non-controlling interest 100,000 Total consideration, net of cash and restricted cash acquired $ 400,191 Less: Accounts receivable 10,722 Property and equipment 4,904 Customer relationships (a)(d) 213,600 Developed technologies (b)(d) 38,900 Trademarks and trade names (c)(d) 13,800 Other assets 13,601 Accounts payable (3,071) Accrued expenses (7,563) Restricted cash payable (125,346) Deferred income taxes (21,941) Other liabilities (9,814) Recorded goodwill $ 272,399 (a) Weighted average life - 7.3 years. (b) Weighted average life - 5.4 years. (c) Weighted average life - 7.3 years. (d) The weighted average life of all amortizable intangible assets acquired in this business combination is 7.0 years. Pavestone Capital, LLC On February 14, 2019, the Company acquired Pavestone Capital, a recourse factoring company that provides working capital to businesses, for a purchase price of $28.0 million, net of cash acquired. This acquisition, which was funded with cash on hand, has been accounted for as a business combination. The Company purchased Pavestone Capital to complement its existing factoring business. As a result, the purchase price is primarily allocated to goodwill, accounts receivable and customer relationships in amounts of $9.5 million, $14.9 million and $3.9 million, respectively. The goodwill associated with this acquisition is deductible for tax purposes. The customer relationships intangible asset has a weighted-average amortization period of 6.5 years. No pro forma information has been disclosed in these financial statements as the operations of Pavestone Capital 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. Noventis, Inc. On January 24, 2019, the Company acquired Noventis, a long-time customer and electronic payments network focused on optimizing payment delivery for bills and invoices to commercial entities, for $338.7 million, which was primarily funded with cash on hand and through borrowings under the 2016 Credit Agreement. Excluded from the consideration was $5.5 million paid to certain Noventis shareholders who held unvested option awards at the acquisition date. The modification of these awards to accelerate the vesting resulted in the Company recording this expense as general and administrative expense in its unaudited condensed consolidated statements of operations for the six months ended June 30, 2019. The Company purchased Noventis to expand its reach as a corporate payments supplier and provide more channels to billing aggregators and financial institutions in our Travel and Corporate Payment Solutions segment. This acquisition was accounted for as a business combination, resulting in the recording of goodwill. The goodwill associated with this acquisition is not deductible for tax purposes. The following is a summary of the final allocation of the purchase price to the assets and liabilities acquired, based on the fair value at the date of acquisition: (In thousands) Total consideration, net of $44,947 in cash acquired $ 293,767 Less: Accounts receivable 22,134 Property and equipment 549 Network relationships (a) (c) 100,900 Developed technologies (b) (c) 15,000 Other assets 2,379 Accounts payable (33,521) Deferred income taxes (21,194) Other liabilities (2,367) Recorded goodwill $ 209,887 (a) Weighted average life - 8.3 years. (b) Weighted average life - 2.9 years. (c) The weighted average life of all amortizable intangible assets acquired in this business combination is 7.6 years. Pro Forma Supplemental Information The pro forma information below gives effect to the Discovery Benefits and Noventis acquisitions as if they had been completed on January 1, 2018. These pro forma results have been calculated after applying the Company’s accounting policies, adjustments to reflect amortization associated with intangibles acquired and interest expense associated with the incremental borrowings under the 2016 Credit Agreement used to fund the acquisitions and related income tax results. The pro forma financial information is presented for comparative purposes only, based on certain estimates and assumptions, which the Company believes to be reasonable but not necessarily indicative of future results of operations or the results that would have been reported if the acquisitions had been completed on January 1, 2018.

Accounts Receivable

Accounts Receivable	6 Months Ended

Receivables [Abstract]
Accounts Receivable	5. Accounts Receivable Accounts receivable consists of amounts billed to and due from customers across a wide range of industries and other third parties. The Company often extends short-term credit to cardholders and pays the merchant for the purchase price, less the fees it retains and records as revenue. The Company subsequently collects the total purchase price from the cardholder. In general, the Company’s trade receivables provide for payment terms of 30 days or less. Receivables not paid in full by payment due dates as stated within the terms of the agreement are generally considered past due and subject to late fees and interest based upon the outstanding receivables balance. The Company discontinues late fee and interest income accruals on outstanding receivables once customers are 90 and 120 days past the invoice due date, respectively. Payments received subsequent to discontinuing late fee and interest income accruals are first applied to outstanding late fees and interest, and the Company resumes accruing interest and late fee income as earned on future receivables balances. The Company extends revolving credit to certain small fleets. These accounts are also subject to late fees and balances that are not paid in full are subject to interest charges based on the revolving balance. The Company had approximately $58.1 million and $62.4 million in receivables with revolving credit balances as of June 30, 2020 and December 31, 2019, respectively. Allowance for Accounts Receivable Receivables are generally written off when they are 150 days past due or upon declaration of bankruptcy of the customer, subject to local regulatory restrictions. The allowance for accounts receivable consists of reserves for both credit and fraud losses. The reserve for credit losses is primarily calculated using historical loss-rates applied at the portfolio level and specific customer balance collectability based on a review of past due accounts receivable balances, changes in payment patterns, and other customer-specific available information. Management further takes into account qualitative factors, such as leading economic and market indicator trends, to the extent they significantly deviate from historical loss-rate trends when determining the need for additional qualitative reserves. The reserve for fraud losses is determined by monitoring pending fraud cases, customer-identified fraudulent activity and unconfirmed suspicious activity in order to make judgments as to probable fraud losses. Accounts receivable are evaluated for impairment on a pooling basis based on similar risk characteristics including industry of the borrower, historical or expected credit loss patterns, risk ratings or classification, and geographic location. See Note 1, Basis of Presentation, for more information. The following tables present changes in the accounts receivable allowances by portfolio segment: Three Months Ended June 30, 2020 Three Months Ended June 30, 2019 (In thousands) Fleet Solutions Travel and Corporate Solutions Health and Employee Benefit Solutions Total Total Balance, beginning of period $ 53,177 $ 16,601 $ 5,648 $ 75,426 $ 46,742 Provision for credit losses 1 18,285 2,241 55 20,581 14,832 Charges to other accounts 2 5,210 — — 5,210 9,550 Charge-offs (32,742) (2,706) (5,318) (40,766) (23,046) Recoveries of amounts previously charged-off 3,078 1 17 3,096 2,413 Currency translation 101 5 190 296 84 Balance, end of period $ 47,109 $ 16,142 $ 592 $ 63,843 $ 50,575 Recorded in: Accounts receivable $ 47,109 $ 11,411 $ 592 $ 59,112 $ 50,575 Other assets — 4,731 — 4,731 — Balance, end of period $ 47,109 $ 16,142 $ 592 $ 63,843 $ 50,575 1 The provision is comprised of estimated credit losses based on the Company’s loss-rate experience and effective January 1, 2020, also includes adjustments required for forecasted credit loss information. The provision for credit losses for the three months ended June 30, 2020, includes estimates of expected credit losses over the contractual life of our receivables as the markets in which the Company operates are experiencing a decline, primarily due to the impact of COVID-19. The provision for credit losses reported within this table also includes the provision for fraud losses. See Note 1, Basis of Presentation, for further details of the adoption of Topic 326 on a modified retrospective basis. 2 The Company earns revenue by assessing monthly finance fees on accounts with overdue balances. These fees are recognized as revenue at the time the fees are assessed. The finance fee is calculated using the greater of a minimum charge or a stated late fee rate multiplied by the outstanding balance that is subject to a late fee charge.

The provision for credit losses for the six months ended June 30, 2020, includes estimates of expected credit losses over the contractual life of our receivables as the markets in which the Company operates are experiencing a decline, primarily due to the impact of COVID-19. The provision for credit losses reported within this table also includes the provision for fraud losses. See Note 1, Basis of Presentation, for further details of the adoption of Topic 326 on a modified retrospective basis. 2 The Company earns revenue by assessing monthly finance fees on accounts with overdue balances. These fees are recognized as revenue at the time the fees are assessed. The finance fee is calculated using the greater of a minimum charge or a stated late fee rate multiplied by the outstanding balance that is subject to a late fee charge. On occasion, these fees are waived to maintain relationship goodwill. Charges to other accounts represents the offset against the late fee revenue recognized when the Company establishes a reserve for such waived amounts. Concentration of Credit Risk The receivables portfolio consists of a large group of homogeneous smaller balances across a wide range of industries, which are collectively evaluated for impairment. No one customer receivable balance represented 10 percent or more of the outstanding receivables balance at June 30, 2020 or December 31, 2019.

Earnings Per Share [Abstract]
Earnings per Share	6. Earnings per Share Basic earnings per share is computed by dividing net income attributable to shareholders by the weighted average number of shares of common stock and vested deferred stock units outstanding during the year. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased for the assumed exercise of dilutive options and the assumed issuance of unvested restricted stock units and performance-based awards, for which the performance condition has been met as of the date of determination, using the treasury stock method unless the effect is anti-dilutive. The treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the average unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase the Company’s common stock at the average market price during the period. The following table summarizes net income attributable to shareholders and reconciles basic and diluted shares outstanding used in the earnings per share computations: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2020 2019 2020 2019 Net income attributable to shareholders $ 72,658 $ 13,807 $ 56,402 $ 29,941 Weighted average common shares outstanding – Basic 43,574 43,329 43,495 43,277 Dilutive impact of share-based compensation awards 205 432 401 390 Weighted average common shares outstanding – Diluted 43,779 43,761 43,896 43,667 For the three and six months ended June 30, 2020, 0.6 million and 0.2 million of outstanding share-based compensation awards were excluded from the computation of diluted earnings per share, respectively, as the effect of including these awards would be anti-dilutive. An immaterial number of outstanding share-based compensation awards were excluded from the computation for the three and six months ended June 30, 2019.

Deposits WEX Bank’s regulatory status enables it to raise capital to fund the Company’s working capital requirements by issuing deposits, subject to FDIC rules governing minimum financial ratios. See Note 18, Supplementary Regulatory Capital Disclosure, for further information concerning these FDIC requirements. WEX Bank accepts its deposits through: (i) certain customers as required collateral for credit that has been extended (“customer deposits”) and (ii) contractual arrangements with brokerage firms for both certificate of deposit and brokered money market deposit products. Customer deposits are generally non-interest bearing, certificates of deposit are issued at fixed rates and brokered money market deposits are issued at variable rates based on LIBOR or the Federal Funds rate. The following table presents the composition of deposits, which are classified as short-term or long-term based on their contractual maturities: (In thousands) June 30, 2020 December 31, 2019 Interest-bearing brokered money market deposits (a) $ 405,701 $ 362,246 Customer deposits 100,158 112,571 Certificates of deposit with maturities within 1 year (a)(b) 649,301 835,996 Short-term deposits 1,155,160 1,310,813 Certificates of deposit with maturities greater than 1 year and less than 5 years (a)(b) 264,198 143,399 Total deposits $ 1,419,358 $ 1,454,212 Weighted average cost of funds on certificates of deposit outstanding 2.16 % 2.57 % Weighted average cost of interest-bearing brokered money market deposits 0.29 % 1.88 % (a) As of June 30, 2020 and December 31, 2019, all certificates of deposit and brokered money market deposits were in denominations of $250 thousand or less, corresponding to FDIC deposit insurance limits.

(c) Contingent on maintaining compliance with the financial covenants as defined in the Company’s 2016 Credit Agreement. 2016 Credit Agreement On February 10, 2020, the Company entered into an eighth amendment (“the Eighth Amendment”) to the 2016 Credit Agreement making certain changes to the previously amended credit agreement, including among other things, effectuating financial covenant amendments and increasing the Company’s capacity to incur additional incremental loan facilities up to $1.4 billion in connection with the acquisition of eNett and Optal . The amendments set forth in the Eighth Amendment were superseded and replaced by the amendments set forth in the Ninth Amendment (as defined below). Such amendments would only become effective concurrently with the closing of the acquisition of eNett and Optal, if it occurs. Refer to Note 4, Acquisitions, for more information regarding the status of this purchase agreement. On June 26, 2020, the Company entered into a ninth amendment ("the Ninth Amendment") to the 2016 Credit Agreement, which made certain changes to the previously amended credit agreement, including among other things, increasing the maximum Consolidated Leverage Ratio to 5.5X through September 30, 2021 with step-downs thereafter, permitting an unlimited amount of corporate cash to be netted from the financial debt balance for financial covenant purposes for a period of time, permanently increasing the amount of corporate cash netting allowed to $250 million, which increases to $400 million if the eNett and Optal transaction closes, and adds a fourth pricing tier in the case that leverage exceeds certain levels and introduces a LIBOR floor on revolving credit facility borrowings of 75 basis points. As of June 30, 2020, under the 2016 Credit Agreement the Company had an outstanding principal amount of $898.7 million on its secured tranche A term loan, an outstanding principal amount of $1.4 billion on its secured tranche B term loan and outstanding letters of credit of $51.3 million drawn against its $820.0 million secured revolving credit facility with a $250.0 million sublimit for letters of credit and $20.0 million sublimit for swingline loans. Under the 2016 Credit Agreement, the Company has granted a security interest in substantially all of the assets of the Company, subject to exceptions including the assets of WEX Bank and certain foreign subsidiaries. The revolving loans and tranche A term loans outstanding under the 2016 Credit Agreement bear interest at variable rates, at the Company’s option, plus an applicable margin determined based on the Company’s consolidated leverage ratio. The tranche B term loans bear interest at a variable rate plus a margin equal to 1.25 percent for base rate loans and 2.25 percent for eurocurrency rate loans. As of June 30, 2020 and December 31, 2019, amounts outstanding under the 2016 Credit Agreement bore a weighted average effective interest rate of 2.3 percent and 4.0 percent, respectively. The Company maintains interest rate swap agreements to manage the interest rate risk associated with its outstanding variable-interest rate borrowings under the 2016 Credit Agreement. See Note 7, Derivative Instruments, for further discussion. The Company accounted for the Ninth Amendment as a debt modification. As part of this transaction, the Company incurred and expensed an insignificant amount of third party costs, which are classified within general and administrative expenses in our unaudited condensed consolidated statements of income. In addition, the Company incurred and capitalized $4.3 million of lender consent fees associated with the amendment. Debt issuance costs incurred and capitalized in conjunction with the 2016 Credit Agreement and its amendments are being amortized into interest expense over the 2016 Credit Agreement’s term using the effective interest method. Debt Covenants As more fully described in the Company’s Annual Report on Form 10 – K for the year ended December 31, 2019, and as amended by the Ninth Amendment to the 2016 Credit Agreement on June 26, 2020, the 2016 Credit Agreement and the Indenture contain covenants that limit the ability of the Company and its subsidiaries, including its restricted subsidiaries and, in certain limited circumstances, WEX Bank and the Company’s other regulated subsidiaries, to (i) incur additional debt, (ii) pay dividends or make other distributions on, redeem or repurchase capital stock, or make investments or other restricted payments, (iii) enter into transactions with affiliates, (iv) dispose of assets or issue stock of restricted subsidiaries or regulated subsidiaries, (v) create liens on assets, or (vi) effect a consolidation or merger or sell all, or substantially all, of the Company’s assets. As of June 30, 2020, the Company was in compliance with all material covenants of its 2016 Credit Agreement and the Indenture. Notes Outstanding As of both June 30, 2020 and December 31, 2019, the Company had $400.0 million of 4.75 percent fixed-rate senior notes outstanding, which will mature on February 1, 2023. Interest is payable semiannually in arrears on February 1 and August 1 of each year. The Company may redeem the Notes at 100.792 percent of principal prior to February 1, 2021. After this date, there is no premium due upon redemption. Upon the occurrence of a change of control of the Company (as defined in the Indenture to the Notes), 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, up to the date of repurchase. Australian Securitization Facility During March 2020, the Company extended its securitized debt agreement with MUFG Bank, Ltd., through April 2021. Under the terms of the agreement, each month, on a revolving basis, the Company sells certain of its Australian receivables to the Company’s Australian Securitization Subsidiary. The Australian Securitization Subsidiary, in turn, uses the receivables as collateral to issue asset-backed commercial paper (“securitized debt”) for approximately 85 percent of the securitized receivables. The amount collected on the securitized receivables is restricted to pay the securitized debt and is not available for general corporate purposes. The Company pays a variable interest rate on the outstanding balance of the securitized debt, based on the Australian Bank Bill Rate plus an applicable margin. The interest rate was 1.04 percent and 1.80 percent as of June 30, 2020 and December 31, 2019, respectively. The Company had $47.8 million and $78.6 million of securitized debt under this facility as of June 30, 2020 and December 31, 2019, respectively, recorded in short-term debt, net. European Securitization Facility The Company maintains a five year securitized debt agreement with MUFG Bank, Ltd., which expires in April 2021. Under the terms of the agreement, the Company sells certain of its receivables from selected European countries to its European Securitization Subsidiary. The European Securitization Subsidiary, in turn, uses the receivables as collateral to issue securitized debt. The amount collected on the securitized receivables is restricted to pay the securitized debt and is not available for general corporate purposes. The amounts of receivables to be securitized under this agreement is determined by management on a monthly basis. The interest rate was 1.11 percent and 0.63 percent as of June 30, 2020 and December 31, 2019, respectively. The Company had $14.8 million and $25.7 million of securitized debt under this facility as of June 30, 2020 and December 31, 2019, respectively, recorded in short-term debt, net. Participation Debt From time to time, WEX Bank enters into participation agreements with third-party banks to fund customers’ balances that exceed WEX Bank’s lending limit to individual customers. Associated unsecured borrowings carry a variable interest rate of 1 month to 3 month LIBOR plus a margin of 225 basis points. The following table provides the amounts outstanding under the participation debt agreements in place at December 31, 2019. There are no amounts outstanding as of June 30, 2020.

Our federal funds lines of credit were $380.0 million and $355.0 million as of June 30, 2020 and December 31, 2019, respectively. There were no outstanding borrowings as of June 30, 2020 and $35.0 million of outstanding borrowings as of December 31, 2019 (matured January 14, 2020).

Off-Balance Sheet Arrangements	10. Off–Balance Sheet Arrangements WEX Europe Services Accounts Receivable Factoring Under a factoring arrangement between WEX Europe Services and an unrelated third-party financial institution, the Company sells customer accounts receivable balances without recourse to the extent that the customer balances are maintained at or below the credit limit established by the buyer. If customer receivable balances exceed the buyer’s credit limit, the Company maintains the risk of default. The Company obtained a true-sale opinion from an independent attorney, which states that the factoring agreement provides legal isolation upon WEX Europe Services bankruptcy or receivership under local law and creates a sale of receivables for amounts transferred both below and above the established credit limits. The Company continues to service these receivables post-transfer with no participating interest. As such, transfers under this arrangement are treated as sales and are accounted for as reductions in trade accounts receivable because effective control of the receivables is transferred to the buyer. The Company sold $75.9 million and $204.7 million of accounts receivable under this arrangement during the three and six months ended June 30, 2020, respectively. For the three and six months ended June 30, 2019, the Company sold $164.3 million and $314.2 million of accounts receivable, respectively. Proceeds received, which are recorded net of applicable costs, including interest and commissions, are recorded in operating activities in the statements of cash flows. The loss on factoring, recorded within cost of services, was $0.4 million and $1.1 million for three and six months ended June 30, 2020, respectively. For the three and six months ended June 30, 2019, the loss on factoring was $0.9 million and $1.8 million, respectively. As of June 30, 2020 and December 31, 2019, the amount of outstanding transferred receivables in excess of the established credit limit was immaterial. Charge-backs on balances in excess of the credit limit during the six months ended June 30, 2020 and June 30, 2019 were insignificant. WEX Bank Accounts Receivable Factoring Under a factoring agreement with an unrelated third-party financial institution, WEX Bank sells certain of its trade accounts receivable under non-recourse transactions. The Company obtained a true-sale opinion from an independent attorney, which states that the factoring agreement provides legal isolation upon WEX Bank bankruptcy or receivership under local law. WEX Bank continues to service the receivables post-transfer with no participating interest. As such, transfers under this arrangement are treated as a sale and are accounted for as a reduction in trade accounts receivable because effective control of the receivables is transferred to the buyer. The Company sold $0.2 billion and $2.9 billion of trade accounts receivable under this arrangement during the three and six months ended June 30, 2020, respectively. During the three and six months ended June 30, 2019, the Company sold $4.0 billion and $6.0 billion of accounts receivable, respectively. Proceeds received, which are reported net of a negotiated discount rate, are recorded in operating activities in the statements of cash flows. The loss on factoring, which is recorded within cost of services in the unaudited condensed consolidated statements of operations, was immaterial for the three and six months ended June 30, 2020, respectively. For the three and six months ended June 30, 2019, the loss on factoring was $1.1 million and $1.7 million, respectively. WEX Latin America Securitization of Receivables Under a securitized debt agreement, WEX Latin America transfers certain unsecured receivables associated with its salary advance payment card product to an investment fund managed by an unrelated third-party. WEX Latin America holds a non-controlling equity interest in the investment fund. During the six months ended June 30, 2020 and 2019, the Company did not make equity contributions to the investment fund. The Company obtained a true-sale opinion from an independent attorney stating that the agreement provides legal isolation upon WEX Latin America bankruptcy or receivership under local law. As such, transfers under this arrangement are treated as sales and are accounted for as reductions in trade accounts receivable. During the three and six months ended June 30, 2020, the Company sold $9.9 million and $28.2 million of receivables, respectively, and recognized a $1.1 million and $4.9 million gain on sale, respectively. During the three and six months ended June 30, 2019, the Company sold $14.9 million and $35.6 million of receivables, respectively, and recognized a $3.5 million and $7.2 million gain on sale, respectively. The gain recognized consists of the difference between the sales price and the carrying value of the receivables and is recorded within other revenue. Cash proceeds from the transfer of these receivables are recorded within operating activities in the condensed consolidated statements of cash flows.

Fair Value Disclosures [Abstract]
Fair Value	12. Fair Value Certain of the Company’s financial assets and liabilities are recorded 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. These valuation techniques may be based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets. • Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3 – Instruments whose significant value drivers are unobservable. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents the Company’s financial instruments that are measured at fair value on a recurring basis: (In thousands) Fair Value Hierarchy June 30, 2020 December 31, 2019 Financial Assets: Money market funds (a) 1 $ 318,354 $ 223,217 Investment securities Municipal bonds 2 $ 233 $ 302 Asset-backed securities 2 229 247 Mortgage-backed securities 2 168 174 Pooled investment fund measured at net asset value (e) 5,000 5,000 Fixed-income mutual fund 1 25,594 24,737 Total investment securities $ 31,224 $ 30,460 Executive deferred compensation plan trust (b) 1 $ 8,074 $ 7,965 Interest rate swaps (c) 2 $ — $ 2,395 Liabilities Interest rate swaps (d) 2 $ 53,865 $ 19,764 (a) The fair value is recorded in cash and cash equivalents. (b) The fair value is recorded in prepaid expenses and other current assets and other assets based on the timing of payment obligations. At June 30, 2020 and December 31, 2019, $0.8 million and $0.9 million of fair value is recorded within prepaid expenses and other current assets, respectively. At June 30, 2020 and December 31, 2019, $7.3 million and $7.0 million of fair value is recorded within other assets, respectively. (c) The fair value is recorded as a current or long-term asset within prepaid expenses and other current assets or other assets depending on the timing of expected discounted cash flows. At December 31, 2019, $2.4 million of fair value is recorded within prepaid and other current assets. (d) The fair value is recorded in other current liabilities or other liabilities depending on the timing of expected discounted cash flows. At June 30, 2020 and December 31, 2019, $21.4 million and $6.7 million of fair value is recorded within other current liabilities, respectively. At June 30, 2020 and December 31, 2019, $32.5 million and $13.1 million of fair value is recorded within other liabilities, respectively. (e) The fair value of this security is measured at net asset value as a practical expedient and has not been classified within the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the condensed consolidated balance sheets. Money Market Funds A portion of the Company’s cash and cash equivalents are invested in money market funds that primarily consist of short-term government securities, which are classified as Level 1 in the fair value hierarchy because they are valued using quoted market prices in an active market. Investment Securities When available, the Company uses quoted market prices to determine the fair value of investment securities; such inputs are classified as Level 1 of the fair-value hierarchy. These securities primarily consist of an open-ended mutual fund, which is invested in fixed-income securities and is held in order to satisfy the regulatory requirements of WEX Bank. For mortgage-backed and asset-backed debt securities and municipal bonds, the Company generally uses quoted prices for recent trading activity of assets with similar characteristics to the debt security or bond being valued. The securities and bonds priced using such methods are generally valued using Level 2 inputs. Pooled Investment Fund (In thousands) Fair Value Unfunded Commitments Redemption Frequency Redemption Notice Period Pooled investment fund, as of June 30, 2020 $ 5,000 — Monthly 30 days The pooled investment fund is a Community Reinvestment Act-eligible investment fund, which seeks to provide bank investors with current income consistent with the returns available in adjustable-rate government guaranteed financial products by investing in Community Development loans guaranteed by the Small Business Administration. The fund maintains individual capital accounts for each investor, which reflect each individual investor’s share of the NAV of the fund. Executive Deferred Compensation Plan Trust The investments held in the executive deferred compensation plan trust are classified as Level 1 in the fair value hierarchy because the fair value is determined using quoted prices for identical instruments in active markets. Interest Rate Swaps The Company determines the fair value of its interest rate swaps based on the discounted cash flows of the difference between the projected fixed payments on the swaps and the implied floating payments using the current LIBOR curve, which are Level 2 inputs of the fair value hierarchy. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The Company had no assets and liabilities measured at fair value on a non-recurring basis as of June 30, 2020 and December 31, 2019. Assets and Liabilities Measured at Carrying Value, for which Fair Value is Disclosed Notes Outstanding The Company determines the fair value of the Notes based on market rates for the issuance of our debt, which are classified as Level 2 in the fair value hierarchy. As of June 30, 2020 and December 31, 2019, the carrying value of the Notes approximated fair value. 2016 Credit Agreement The Company determines the fair value of the amount outstanding under its 2016 Credit Agreement based on the market rates for the issuance of the Company’s debt, which are Level 2 inputs in the fair value hierarchy. As of June 30, 2020, the fair value of the tranche A and tranche B loans was $880.8 million and $1.39 billion, respectively. At December 31, 2019, the carrying value of the 2016 Credit Agreement, including both tranche A and tranche B loans, approximated fair value.

Noncontrolling Interest [Abstract]
Redeemable Non-Controlling Interest	13. Redeemable Non-Controlling Interest On March 5, 2019, the Company acquired Discovery Benefits, an employee benefits administrator. The seller of Discovery Benefits obtained a 4.9 percent equity interest in the newly formed parent company of WEX Health and Discovery Benefits (the “U.S. Health business”). The seller’s 4.9 percent non-controlling interest in the U.S. Health business was initially established at both carrying value and fair value. On the date of acquisition, the excess of the fair value of the 4.9 percent equity interest in WEX Health over its carrying value was recognized as an equity transaction, resulting in a $41.4 million increase to additional paid-in capital. Remeasurement of the equity interest to fair value during the first quarter of 2019 resulted in an increase to redeemable non-controlling interest of $41.4 million and an offsetting decrease to retained earnings that did not impact earnings per share. The agreement provides the seller with a put right and the Company with a call right for the equity interest, which can be exercised no earlier than seven years following the date of acquisition. Upon exercise of the put or call right, the purchase price is calculated based on a revenue multiple of peer companies (as described in the operating agreement for the U.S. Health business) applied to trailing twelve month revenues of the U.S. Health business. The put option makes the non-controlling interest redeemable and, therefore, the non-controlling interest is classified as temporary equity outside of stockholders’ equity. The Company calculates the redemption value of the redeemable non-controlling interest on a quarterly basis using revenue multiples as determined in accordance with the operating agreement for the U.S. Health business and as described above. The redeemable non-controlling interest is reported at the higher of its redemption value or the non-controlling interest holder’s proportionate share of the U.S. Health business’ net carrying value. Any resulting change in the value of the redeemable non-controlling interest is offset against retained earnings and impacts earnings per share. The following table presents the changes in the Company’s redeemable non-controlling interest: (In thousands) 2020 2019 Balance at December 31 $ 156,879 $ — Acquisition of Discovery Benefits at fair value — 25,757 Establishing redeemable non-controlling interest for WEX Health at carrying value — 32,843 Adjustment to redeemable non-controlling interest to reflect WEX Health at fair value — 41,400 Net income (loss) attributable to redeemable non-controlling interest 142 (7) Change in value of redeemable non-controlling interest 2,624 — Balance at March 31 $ 159,645 $ 99,993 Net income attributable to redeemable non-controlling interest 99 14 Change in value of redeemable non-controlling interest (59,940) 17,720 Balance at June 30 $ 99,804 $ 117,727

Income Tax Disclosure [Abstract]
Income Taxes	14. Income Taxes The Company’s effective tax rate was 310.8 percent and 104.6 percent for the second quarter and first half of 2020, respectively, as compared to 28.0 percent and 27.5 percent for the second quarter and first half of 2019, respectively. Income tax expense is based on an estimated annual effective rate, which requires the Company to make its best estimate of annual pretax income or loss. The significant increase in the Company’s tax rate was primarily due to the jurisdictional earnings mix and decrease in estimated income before income taxes for the current year with relatively significant non-deductible expenses. The Company's effective tax rate for the second quarter and first half of 2020 included a discrete tax benefit of $9.8 million reflecting an additional tax basis related to the acquisition of Discovery Benefits, partially offset by a valuation allowance of $5.3 million recognized against the beginning of the year deferred tax assets for the Brazil subsidiary. No tax benefit related to temporary differences and carryforwards arising in the current year for the Brazil subsidiary are included in the estimated annual effective tax rate for 2020. Undistributed earnings of certain foreign subsidiaries of the Company amounted to $62.5 million and $77.4 million at June 30, 2020 and December 31, 2019, respectively. These earnings and profits are considered to be indefinitely reinvested. Upon distribution of these earnings in the form of dividends or otherwise, the Company would be subject to withholding taxes payable to foreign countries, where applicable, but would generally have no further federal income tax liability.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	15. Commitments and Contingencies Litigation The Company is subject to legal proceedings and claims in the ordinary course of business. On May 11, 2020, the shareholders of eNett and Optal each initiated separate legal proceedings against the Company denying that there has been a Material Adverse Effect and alleging that the Company has threatened to breach its obligations under the terms of the purchase agreement. The claimants seek a declaration that no Material Adverse Effect has occurred and orders for specific performance of WEX's obligations under the purchase agreement. WEX intends to vigorously defend against these claims. A London court set September 21, 2020 as the starting date of a trial of certain preliminary issues. We are unable to predict the outcome of these proceedings. Commitments Significant commitments and contingencies as of June 30, 2020 are consistent with those discussed in Note 21, Commitments and Contingencies, to the consolidated financial statements in the Annual Report on Form 10–K for the year ended December 31, 2019.

Stock-Based Compensation

Stock-Based Compensation	6 Months Ended

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	16. Stock–Based Compensation The Company regularly grants equity awards under its stockholder-approved equity plans to certain employees and directors. The fair value of restricted stock units, deferred stock units and performance-based restricted stock units, excluding total shareholder return (“TSR”) awards, is based on the closing market price of the Company’s stock on the grant date as reported by the NYSE. The fair value of each service-based stock option award is estimated on the grant date using a Black-Scholes-Merton option-pricing model. The fair value of market-based awards, including TSRs, is estimated on the grant date using a Monte-Carlo simulation pricing model. Given the economic uncertainty and business disruption created by the COVID-19 pandemic, effective June 23, 2020 the Company's Compensation Committee approved certain modifications to performance-based restricted stock units previously granted on March 16, 2020 and March 20, 2019. Such changes included replacing Company performance metrics with total shareholder return metrics for the March 16, 2020 awards, and for the March 20, 2019 awards, adding a relative TSR modifier to scale the payment up or down by +/- 15 percent. Additionally, the Company granted certain employees new TSR awards on June 24, 2020. Attainment of the Company's TSR awards is tied to our TSR relative to the S&P 400 from the time of modification (for awards modified on June 23, 2020) or grant date (for awards granted on June 24, 2020). Given that these are market-based performance awards, the fair value is calculated by the Monte Carlo simulation valuation model. The key inputs for the fair values by grant date are outlined below: Grant date 6/24/2020 6/24/2020 3/16/2020 3/20/2019 Recipient(s) Non-CEO CEO All All Modification date N/A N/A 6/23/2020 6/23/2020 Risk-free rate 0.21% 0.21% 0.20% 0.18% Stock price 1 $160.14 $160.14 $173.15 $173.15 Volatility 47.72% 47.72% 51.32% 62.29% Performance period June 24, 2020 – June 24, 2020 – June 23, 2020 – December 31, 2022 June 23, 2020 – December 31, 2021 Shares at target 110,467 28,101 199,870 86,845 Fair value per share 2 $264.17 $240.55 $280.93 $188.21 1 At the date of grant or modification date, whichever is applicable. 2 At the date of grant or modification date, whichever is applicable. The CEO's June 24, 2020 award has a one-year post-vesting holding period. For the Company's awards that were modified on June 23, 2020, the final attainment for recipients other than executive officers will be based on the greater of the payout under the original awards performance metrics or the modified metrics. As a result, the Company is required to assess which payout is more likely and adjust the expense accordingly. If the original awards performance metrics are expected to result in a higher number of shares vesting, then the expense recorded will be based on awards expected to vest at the grant-date stock price. Alternatively, if the modified metrics are expected to result in a higher number of shares vesting, then the expense recorded will be based on the fair value calculated using the Monte Carlo simulation valuation model. The fair value of equity awards granted totaled $43.9 million and $101.7 million during the three and six months ended June 30, 2020, respectively, and $7.1 million and $45.2 million during the three and six months ended June 30, 2019, respectively. The fair value of restricted stock units, deferred stock units and performance-based restricted stock units (excluding TSRs) is based on the closing market price of the Company’s stock on the grant date as reported by the NYSE. We used the Monte Carlo simulation valuation model to estimate the fair value of TSRs. The fair value of each service-based stock option award is estimated on the grant date using a Black-Scholes-Merton option-pricing model.

Debt Disclosure [Abstract]
Supplementary Regulatory Capital Disclosure	18. Supplementary Regulatory Capital Disclosure The Company’s subsidiary, WEX Bank, is subject to various regulatory capital requirements administered by the FDIC and the Utah Department of Financial Institutions. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, WEX Bank must meet specific capital guidelines that involve quantitative measures of WEX Bank’s assets, liabilities and certain off-balance sheet items. WEX Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Failure to meet minimum capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could limit our business activities and have a material effect on our business, results of operations and financial condition. Quantitative measures established by regulation to ensure capital adequacy require WEX Bank to maintain minimum amounts and ratios as defined in the regulations. As of June 30, 2020, the most recent FDIC exam report categorized WEX Bank as “well capitalized” under the regulatory framework for prompt corrective action. There are no conditions or events subsequent to that examination report that management believes have changed WEX Bank’s capital rating. The following table presents WEX Bank’s actual and regulatory minimum capital amounts and ratios: (In thousands) Actual Amount Ratio Minimum for Capital Adequacy Purposes Amount Ratio Minimum to Be Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio June 30, 2020 Total Capital to risk-weighted assets $ 294,145 15.94 % $ 147,619 8.0 % $ 184,524 10.0 % Tier 1 Capital to average assets $ 280,009 11.20 % $ 99,969 4.0 % $ 124,962 5.0 % Common equity to risk-weighted assets $ 280,009 15.17 % $ 83,036 4.5 % $ 119,941 6.5 % Tier 1 Capital to risk-weighted assets $ 280,009 15.17 % $ 110,715 6.0 % $ 147,619 8.0 % December 31, 2019 Total Capital to risk-weighted assets $ 329,276 13.54 % $ 194,566 8.0 % $ 243,208 10.0 % Tier 1 Capital to average assets $ 314,466 10.88 % $ 115,583 4.0 % $ 144,479 5.0 % Common equity to risk-weighted assets $ 314,466 12.93 % $ 109,443 4.5 % $ 158,085 6.5 % Tier 1 Capital to risk-weighted assets $ 314,466 12.93 % $ 145,925 6.0 % $ 194,566 8.0 %

Subsequent Events [Abstract]
Subsequent Events	19. Subsequent Events Private Investment Placement Pursuant to a purchase agreement dated June 29, 2020, on July 1, 2020, the Company closed on a private investment placement with an affiliate of Warburg Pincus LLC (together with its affiliate, "Warburg Pincus"), pursuant to which the Company issued convertible senior notes due 2027 in an aggregate principal amount of $310 million ("the Convertible Notes") and 577,254 shares of common stock, with gross proceeds of $90 million, reflecting a price of $155.91 per share. The issuance of the Convertible Notes provided the Company with net proceeds of approximately $299 million after original issue discount, and have a seven-year term. Interest on the Convertible Notes is calculated at a rate of 6.5% per annum, payable semi-annually in arrears, with the first interest payment due January 15, 2021. At WEX's option, interest is either payable in cash, through accretion to the principal amount of the Convertible Notes, or a combination of cash and accretion. The Convertible Notes may be converted at any time at the option of holders of the Convertible Notes, based on an initial conversion price of $200 per share, subject to certain adjustments. Conversions of the Convertible Notes may be settled in shares of WEX common stock, cash, or a combination thereof at WEX's election. WEX will have the right, at any time following the third anniversary of closing, to redeem the Convertible Notes in whole or in part if the closing price of WEX's common stock is at least 200% of the conversion price of the Convertible Notes for 20 trading days (whether or not consecutive) out of any 30 consecutive trading day period prior to the time WEX delivers a redemption notice, (including at least one of the five trading days immediately preceding the last day of such 30 trading day period), subject to the right of holders of the Convertible Notes to convert its Convertible Notes prior to the redemption date. In the event of certain fundamental change transactions, including certain change of control transactions and delisting events, holders of the Convertible Notes will have the right to require WEX to repurchase its Convertible Notes in accordance with the terms of the Convertible Notes. Tenth Amendment to the 2016 Credit Agreement On July 29, 2020, the Company entered into the tenth amendment to the 2016 Credit Agreement, which increased commitments under the Company's secured revolving credit facility from $820 million to $870 million.

Accounting Changes and Error Corrections [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10–Q and Rule 10–01 of Regulation S–X. Accordingly, they do not include all information and notes required by GAAP for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the financial statements that are included in the Company’s Annual Report on Form 10–K for the year ended December 31, 2019, filed with the SEC on February 28, 2020. In the opinion of management, all adjustments considered necessary for a fair presentation, which are of a normal recurring nature, have been included. Operating results for the three and six months ended June 30, 2020 are not necessarily indicative of the results for any future periods or the year ending December 31, 2020. With the exception of accounting policies over credit loss reserves, which were impacted by the adoption of ASU 2016–13 effective January 1, 2020 (refer to Note 2, Recent Accounting Pronouncements), we have applied the same accounting policies in preparing these quarterly financial statements as we did in preparing our 2019 annual financial statements. The Company rounds amounts in the unaudited condensed consolidated financial statements to thousands and calculates all per-share data from underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot or recalculate based on reported numbers due to rounding.
Allowance for Accounts Receivable	The Company adopted Topic 326 on January 1, 2020, utilizing the modified-retrospective approach, under which prior period comparable financial information was not adjusted. Topic 326 amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables and off-balance sheet credit exposures. See Note 2, Recent Accounting Pronouncements, for further information regarding this new accounting standard. The following table illustrates the adoption impact of Topic 326: January 1, 2020 (In thousands) Prior to Adoption Impact of As Reported Allowance for accounts receivable 1 $ 52,274 $ 11,577 $ 63,851 Deferred income taxes, net (within total assets) $ 12,833 $ 570 $ 13,403 Deferred income taxes, net (within total liabilities) $ 218,740 $ (2,230) $ 216,510 Retained earnings $ 1,539,201 $ (8,587) $ 1,530,614 Non-controlling interest $ 9,575 $ (190) $ 9,385 1 This impact does not reflect the economic disruption resulting from the COVID-19 pandemic since it occurred subsequent to January 1, 2020. Allowance for Accounts Receivable The allowance for accounts receivable reflects management’s current estimate of uncollectible balances on its accounts receivable and consists primarily of reserves for credit losses. As a result of the adoption of Topic 326, the reserve for expected credit losses includes both a quantitative and qualitative reserve component. The quantitative component is primarily calculated using an analytic model, which includes the consideration of historical loss experience and past events to calculate actual loss-rates at the portfolio level. It also includes reserves against specific customer account balances determined to be at risk for non-collection based on customer information including delinquency, changes in payment patterns and other information. The qualitative component is determined through analyzing recent trends in economic indicators and other current and forecasted information to determine whether loss-rates are expected to change significantly in comparison to historical loss-rates at the portfolio level. When such indicators are forecasted to trend a predetermined amount from the historical median, the Company qualitatively determines what impact, if any, the trends are expected to have on the reserve for expected credit losses. Economic indicators include consumer price indexes, consumer spending and unemployment trends, among others. See Note 5, Accounts Receivable, for discussion regarding the adjustments made during the three and six months ended June 30, 2020 as a result of these assessments. Accounts receivable are evaluated for impairment on a pooling basis based on similar risk characteristics including industry of the borrower, historical or expected credit loss patterns, risk ratings or classification, and geographic location. As a result of this evaluation, our portfolio segments consist of the following: • Fleet Solutions - The majority of the customer base consists of companies within the transportation, logistics and fleet industries. The associated credit losses by customer are generally low, however, the Fleet Solutions segment has historically comprised the majority of the Company’s provision for credit loss. Credit losses generally correlate with changes in consumer price indices and other indices that measure trends and volatility including the Institute of Supply Management Purchasing Index and the U.S. Volatility Index. • Travel and Corporate Solutions - The customer base is comprised of businesses operating in a wide range of industries including large online travel agencies. With the exception of the Noventis portfolio, which has minimal credit risk due to its business model and collection terms, the associated credit losses are sporadic and closely correlate with trends in consumer metrics, including consumer spending and the consumer price index. • Health and Employee Benefit Solutions - The customer base includes third-party administrators, individual employers and employees. The associated credit losses are generally low. Prior to entering into the WEX Latin America accounts receivable securitization arrangement as described in Note 10, Off-Balance Sheet Arrangements, the Company maintained credit exposure on these receivables and accordingly established an allowance for credit losses, which is included in the Health and Employee Benefit Solutions balance as of June 30, 2020, as disclosed in Note 5, Accounts Receivable. When individual accounts receivable exhibit elevated credit risk characteristics as a result of bankruptcies, disputes, conversations with customers, or other significant credit loss events, they are assessed individual credit loss estimates. Assumptions regarding expected credit losses are reviewed each reporting period and may be impacted by actual performance of accounts receivable and changes in any of the factors discussed above. The allowance for accounts receivable also includes reserves for waived finance fees, which are used to maintain customer goodwill and recorded against the late fee revenue recognized, as well as reserves for fraud losses. Management monitors known and suspected fraudulent activity identified by the Company, as well as fraudulent claims reported by customers, in estimating the reserve for expected fraud losses.
Off-Balance-Sheet Arrangements	Off-Balance Sheet Arrangements The Company has various off-balance sheet commitments, certain of which carry credit risk exposure. These items were not significantly impacted by the adoption of Topic 326 as of June 30, 2020: • Extension of credit to customers - The Company has entered into commitments to extend credit in the ordinary course of business as part of established customer agreements. The unfunded portion of an extension of credit to customers fluctuates as the Company increases or decreases customer credit limits, subject to appropriate credit reviews. Given that the Company can generally adjust its customers’ credit lines at its discretion at any time, the unfunded portion of loan commitments to customers is unconditionally cancellable and thus the Company has not established a liability for expected credit losses on those commitments. • Accounts receivable factoring - See Note 10, Off-Balance Sheet Arrangements, for the terms of the factoring arrangements for the Company’s subsidiaries, WEX Europe Services and WEX Bank. Within the terms of the Company’s WEX Europe Services accounts receivable factoring arrangement, the Company has credit risk exposure to the extent outstanding transferred receivables exceed established credit limits. The Company does not maintain any beneficial interest with respect to the receivables sold, and as such does not maintain any credit risk related to receivables transferred below the established credit limit. The amount by which factored receivables exceed the credit limit is insignificant as of June 30, 2020. Management deems expected credit losses arising from this off-balance sheet commitment to be insignificant and did not establish a corresponding liability. The Company does not retain any beneficial interest in WEX Bank’s factored receivables, and the terms of the agreement do not describe a scenario in which the Company would be exposed to credit risk as it relates to the transferred receivables.
New Accounting Standards	Standard Description Date/Method of Adoption Effect on financial statements or other significant matters Adopted During the Six Months Ended June 30, 2020 ASU 2016–13 This standard amends the impairment model to utilize an expected loss methodology in place of the incurred loss methodology for financial instruments, including trade receivables and off-balance sheet credit exposures. The standard requires entities to consider a broader range of information to estimate expected credit losses, including historical experience, current conditions and reasonable and supportable forecasts that impact the collectability of the reported amount. The Company adopted ASU 2016–13 effective January 1, 2020 using the modified-retrospective approach. The amendments of this new standard were applied through a cumulative-effect adjustment to total stockholders’ equity of $8.8 million, net of a $2.8 million income tax benefit, as of January 1, 2020. This adjustment was driven by the incorporation of economic forecasts into the Company’s expected credit loss reserve methodology. The unaudited condensed consolidated financial statements for the three and six months ended June 30, 2020 are presented under the new standard. Comparative periods presented have not been adjusted. Refer to Note 1, Basis of Presentation, for discussion of the Company’s credit loss methodology. Not Adopted as of June 30, 2020 ASU 2020 – 04, Reference Rate Reform This standard provides optional guidance for a limited period of time to ease the potential financial reporting burden in accounting for (or recognizing the effects of) the discontinuation of LIBOR resulting from reference rate reform. The amendments provide optional expedients and exceptions for applying GAAP to contracts and other transactions impacted by reference rate reform. If certain criteria are met, an entity will not be required to remeasure or reassess contracts impacted by reference rate reform. Election is available through December 31, 2022. The Company is currently evaluating the implications of these amendments to its current efforts for reference rate reform implementation and any impact the adoption of this ASU would have on its financial condition and results of operations.
Receivables	Accounts receivable consists of amounts billed to and due from customers across a wide range of industries and other third parties. The Company often extends short-term credit to cardholders and pays the merchant for the purchase price, less the fees it retains and records as revenue. The Company subsequently collects the total purchase price from the cardholder. In general, the Company’s trade receivables provide for payment terms of 30 days or less. Receivables not paid in full by payment due dates as stated within the terms of the agreement are generally considered past due and subject to late fees and interest based upon the outstanding receivables balance. The Company discontinues late fee and interest income accruals on outstanding receivables once customers are 90 and 120 days past the invoice due date, respectively. Payments received subsequent to discontinuing late fee and interest income accruals are first applied to outstanding late fees and interest, and the Company resumes accruing interest and late fee income as earned on future receivables balances.
Earnings per Share	Basic earnings per share is computed by dividing net income attributable to shareholders by the weighted average number of shares of common stock and vested deferred stock units outstanding during the year. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased for the assumed exercise of dilutive options and the assumed issuance of unvested restricted stock units and performance-based awards, for which the performance condition has been met as of the date of determination, using the treasury stock method unless the effect is anti-dilutive. The treasury stock method assumes that proceeds, including cash received from the exercise of employee stock options and the average unrecognized compensation expense for unvested share-based compensation awards, would be used to purchase the Company’s common stock at the average market price during the period.
Derivative Instruments	The Company is exposed to certain market risks relating to its ongoing business operations. From time to time, the Company enters into derivative instrument arrangements to manage various risks including interest rate risk
Fair Value of Financial Instruments	Certain of the Company’s financial assets and liabilities are recorded 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. These valuation techniques may be based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1 – Quoted prices for identical instruments in active markets. • Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3 – Instruments whose significant value drivers are unobservable. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Money Market Funds A portion of the Company’s cash and cash equivalents are invested in money market funds that primarily consist of short-term government securities, which are classified as Level 1 in the fair value hierarchy because they are valued using quoted market prices in an active market. Investment Securities When available, the Company uses quoted market prices to determine the fair value of investment securities; such inputs are classified as Level 1 of the fair-value hierarchy. These securities primarily consist of an open-ended mutual fund, which is invested in fixed-income securities and is held in order to satisfy the regulatory requirements of WEX Bank. For mortgage-backed and asset-backed debt securities and municipal bonds, the Company generally uses quoted prices for recent trading activity of assets with similar characteristics to the debt security or bond being valued. The securities and bonds priced using such methods are generally valued using Level 2 inputs. The pooled investment fund is a Community Reinvestment Act-eligible investment fund, which seeks to provide bank investors with current income consistent with the returns available in adjustable-rate government guaranteed financial products by investing in Community Development loans guaranteed by the Small Business Administration. The fund maintains individual capital accounts for each investor, which reflect each individual investor’s share of the NAV of the fund. Executive Deferred Compensation Plan Trust The investments held in the executive deferred compensation plan trust are classified as Level 1 in the fair value hierarchy because the fair value is determined using quoted prices for identical instruments in active markets. Interest Rate Swaps The Company determines the fair value of its interest rate swaps based on the discounted cash flows of the difference between the projected fixed payments on the swaps and the implied floating payments using the current LIBOR curve, which are Level 2 inputs of the fair value hierarchy.
Segment Information	The Company determines its operating segments and reports segment information in accordance with how the Company’s chief operating decision maker (“CODM”) allocates resources and assesses performance. The Company’s CODM is its Chief Executive Officer. The operating segments are aggregated into the three reportable segments described below. • Fleet Solutions provides customers with payment and transaction processing services specifically designed for the needs of commercial and government fleets. This segment also provides information management services to these fleet customers. • Travel and Corporate Solutions focuses on the complex payment environment of business-to-business payments, providing customers with payment processing solutions for their corporate payment and transaction monitoring needs. • Health and Employee Benefit Solutions

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