Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies General World Fuel Services Corporation (the “Company”) was incorporated in Florida in July 1984 and along with its consolidated subsidiaries is referred to collectively in this Quarterly Report on Form 10‑Q (“10-Q Report”) as “World Fuel,” “we,” “our” and “us.” We are a leading global fuel services company, principally engaged in the distribution of fuel and related products and services in the aviation, marine and land transportation industries. In recent years, we have expanded our product and service offerings to include energy advisory services and supply fulfillment with respect to natural gas and power and transaction and payment management solutions to commercial and industrial customers. Our intention is to become a leading global energy management company offering a full suite of energy advisory, management and fulfillment services, technology solutions as well as sustainability products and services across the energy product spectrum. We also offer payment management solutions to commercial and industrial customers, principally in the aviation, land and marine transportation industries. We will continue to focus on enhancing the portfolio of products and services we provide based on changes in customer demand, including sustainability offerings and renewable fuel products. We prepared the Consolidated Financial Statements following the requirements of the United States (“U.S.”) Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the U.S. (“U.S. GAAP”) can be condensed or omitted. Revenues, expenses, assets and liabilities can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be representative of those for the full year. In our opinion, all adjustments necessary for a fair statement of the financial statements, which are of a normal and recurring nature, have been made for the interim periods reported. The information included in this 10-Q Report should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in our 2019 Annual Report on Form 10-K (“ 2019 10-K Report”). Certain amounts in the Consolidated Financial Statements and accompanying notes may not add due to rounding. All percentages have been calculated using unrounded amounts. COVID-19 The outbreak of COVID-19, which was declared a pandemic by the World Health Organization in March 2020, has created significant volatility, uncertainty and disruption in the global economy. The rapid spread of the virus has caused governments around the world to implement stringent measures to help control its spread, including, without limitation, quarantines, “stay-at-home” or “shelter-in-place” orders, social-distancing mandates, travel restrictions, and closures or reduced operations for businesses, governmental agencies, schools and other institutions, among others. Beginning in the quarterly period ended March 31, 2020, the aviation, marine and land transportation industries, along with global economic conditions generally, have been significantly disrupted by the pandemic. A large number of our customers in these industries have experienced substantial reductions in their operations due to travel restrictions and stay-at-home orders, as well as the extended shutdown of various businesses in affected regions. Furthermore, government measures have also led to a precipitous decline in fuel prices in response to concerns about demand for fuel, further exacerbated by recent disagreements regarding crude oil production levels between the Organization of Petroleum Exporting Countries (OPEC) members and other oil-producing countries such as Russia, as well as related global storage considerations. While the pandemic and associated impacts on economic activity had a limited adverse effect on our operating results for the quarterly period ended March 31, 2020, we have since seen a significant decline in demand and related sales volume as large sectors of the global economy have been adversely impacted by the crisis. In response to these developments, in March 2020, we took swift action to ensure the safety of our employees and other stakeholders, and initiated a number of initiatives relating to cost reduction, liquidity and operating efficiencies. We make estimates and assumptions that affect the reported amounts on our financial statements and accompanying notes as of the date of the financial statements. We assessed accounting estimates that require consideration of forecasted financial information, including, but not limited to, our allowance for credit losses, the carrying value of our goodwill, intangible assets, and other long-lived assets. This assessment was conducted in the context of information reasonably available to us, as well as our consideration of the future potential impacts of COVID-19 on our business as of March 31, 2020. At this time, we are unable to predict with specificity the ultimate impact of the crisis, as it will depend on the magnitude, severity and duration of the pandemic, as well as how quickly, and to what extent, normal economic and operating conditions resume on a sustainable basis globally. Accordingly, if the impact is more severe or longer in duration than we have assumed, such impact could potentially result in impairments and increases in credit allowances. Significant Accounting Policies There have been no significant changes, other than those related to the adopted new accounting standards below, in the Company's accounting policies from those disclosed in our 2019 10‑K Report. The significant accounting policies we use for quarterly financial reporting are disclosed in Note 1. Basis of Presentation, New Accounting Standards and Significant Accounting Policies of the accompanying notes to the Consolidated Financial Statements included in our 2019 10‑K Report, and in the section below Adoption of New Accounting Standards. Adoption of New Accounting Standards We included below a description of recent new accounting standards or accounting standards updates that had an impact on the Company’s consolidated financial statements. New accounting standards or accounting standards updates not listed below were assessed and determined to be either not applicable or did not have a material impact on the Company’s consolidated financial statements or processes. Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. In June 2016, Accounting Standards Update ("ASU") 2016-13 was issued, which replaced the incurred loss impairment model with a model that reflects expected credit losses over the lifetime of the asset and requires consideration of a broader range of reasonable and supportable information to determine credit loss estimates. The guidance in this update, including the subsequent related codification amendments, changed how entities account for credit impairment from trade and other receivables, net investments arising from sales-type and direct financing leases, debt securities, purchased-credit impaired financial assets and other instruments in addition to loans. For receivables and certain other instruments that are not measured at fair value, entities are required to estimate expected credit losses. Under the expected loss model, an entity recognizes a loss upon initial recognition of the asset that reflects all future events that could lead to a loss being realized, regardless of whether it is probable that the future event will occur. The Company adopted ASU 2016-13, including the related codification amendments, in the first quarter of 2020 utilizing the modified retrospective transition method and applying the transition provisions at the effective date. The Company implemented changes to business processes and internal controls that support the new standard. As of the date of implementation on January 1, 2020, the Company recognized $11.1 million as a reduction to the opening retained earnings balance. The main drivers of the consolidated impact at transition are related to the inclusion of future economic conditions, the exclusion of freestanding credit enhancements when estimating the expected credit loss and estimating the lifetime credit losses of notes receivable. Accounting Standards Issued but Not Yet Adopted There have been no recently issued accounting standards not yet adopted by us which are expected, upon adoption, to have a material impact on the Company’s Consolidated Financial Statements or processes.

Accounts Receivable

Accounts Receivable	3 Months Ended
	Mar. 31, 2020
Receivables [Abstract]
Accounts Receivable	Accounts Receivable Accounts receivable and allowance for credit losses We extend credit on an unsecured basis to most of our customers. Our exposure to expected credit losses depends on the financial condition of our customers and other macroeconomic factors beyond our control, such as deteriorating conditions in the world economy or in the industries we serve, changes in oil prices and political instability. While we actively manage our credit exposure and work to respond to both changes in our customers’ financial conditions or macroeconomic events, there can be no guarantee we will be able to mitigate all of these risks successfully. We perform ongoing credit evaluations of our customers and adjust credit limits based upon payment history and the customer’s current creditworthiness based on expected exposure. Our payment terms with customers are based on each customers' creditworthiness and are generally 30-60 days, although certain markets and other customer-specific factors may warrant longer payment terms. Accounts receivable balances that are not paid within the terms of the sales agreement may be subject to finance fees based on the outstanding balance. Although we analyze customers’ payment history and expected creditworthiness, since we extend credit on an unsecured basis to most of our customers, there is a possibility that any accounts receivable not collected may ultimately need to be written off. Accounts receivable are measured at amortized cost. The health of our receivables is continuously monitored using a risk-based model, taking into consideration both the timeliness and predictability of collections from our customers. We maintain a provision for expected credit losses based upon our historical experience with our customers, along with any specific customer collection issues that we have identified from current financial information and business prospects, as well as any political or economic conditions or other market factors, including certain assumptions based on reasonable forward-looking information from market sources. Principally, based on these credit risk factors, portfolio segments are defined and an internally derived risk-based credit loss reserve is established and applied to each portfolio segment. Customer account balances that are deemed to be at high risk of collectability are reserved at higher rates than customer account balances which we expect to collect without difficulty. We had accounts receivable of $2.0 billion and $2.9 billion as of March 31, 2020 and December 31, 2019, respectively. We also had allowance for credit losses related to accounts receivables and other insignificant financing receivables of $56.1 million (including the $11.1 million cumulative transition adjustment to retained earnings related to the implementation of ASU 2016-13) and $35.5 million , as of March 31, 2020 and December 31, 2019 , respectively. Changes to the expected credit loss provision during the three months ended March 31, 2020 include global economic outlook considerations as a result of the Company’s assessment of reasonable and supportable forward-looking information. Based on an aging analysis at March 31, 2020 , 96% of our net accounts receivable were outstanding less than 60 days. The following table sets forth activities in our allowance for credit losses (in millions): Total Balance as of January 1, 2020 $ 46.6 Charges to provision for credit losses 9.9 Write-off of uncollectible receivables (0.6 ) Recoveries of credit losses $ 0.1 Translation adjustments — Balance as of March 31, 2020 $ 56.1 Financing programs We have accounts receivable financing programs under receivables purchase agreements (“RPAs”) with Wells Fargo Bank, N.A. and Citibank, N.A. that allow for the sale of our accounts receivable in an amount up to 100% of our outstanding qualifying accounts receivable balances and receive cash consideration equal to the total balance, less a discount margin equal to LIBOR plus 1% to 3% . Accounts receivable sold under the RPAs are accounted for as sales, in accordance with FASB ASC Topic 860, Transfers and Servicing , and excluded from Accounts receivable, net on the accompanying Consolidated Balance Sheets. Fees and interest paid under the RPAs are recorded within Interest expense and other financing costs, net on the Consolidated Statements of Comprehensive Income. Under the RPAs, accounts receivable sold, which remained outstanding as of March 31, 2020 and December 31, 2019 , were $288.3 million and $405.9 million , respectively. The fees and interest paid under the RPAs were $4.4 million and $5.8 million for the three months ended March 31, 2020 and 2019 , respectively. For the three months ended March 31, 2020 and 2019 , cash payments to the owners of account receivables were $1.8 billion and $2.0 billion , respectively, and cash proceeds from the sale of account receivables were $1.7 billion and $2.0 billion , respectively.

Business Combinations [Abstract]
Acquisitions	Acquisitions 2020 Acquisition During the three months ended March 31, 2020 , we completed the acquisition of the aviation fuel business from Universal Weather and Aviation, Inc. (“UVair fuel business”), which serves business and general aviation customers worldwide. The acquisition was accounted for as a business combination. The following table summarizes the aggregate consideration paid for this acquisition and the provisional amounts of the assets acquired and liabilities assumed, recognized at the acquisition date. The Company is in the process of obtaining information to finalize the valuations of certain acquired assets and assumed liabilities. Thus, the provisional measurements of these acquired assets and assumed liabilities are subject to change and will be finalized no later than one year from the acquisition date (amounts in millions): Total Cash paid for acquisition of business $ 131.0 Amounts due to sellers 30.0 Estimated purchase price $ 161.0 Assets acquired: Accounts receivable 40.1 Goodwill and identifiable intangible assets 127.1 Other current and long-term assets 4.5 Liabilities assumed: Accounts payable (9.9 ) Other current and long-term liabilities (0.9 ) Estimated purchase price $ 161.0 The goodwill of $82.9 million was assigned to the aviation segment, of which $73.5 million is anticipated to be deductible for tax purposes, and is attributable primarily to the expected synergies and other benefits that we believe will result from combining the acquired operations with the aviation segment operations. The identifiable intangible assets were $44.3 million , and primarily consisted of customer relationships and other identifiable assets. The financial position, results of operations and cash flows of this acquisition have been included in our Consolidated Financial Statements since the acquisition date and did not have a material impact on our consolidated revenue and net income for the three months ended March 31, 2020 ; accordingly, pro forma information for this acquisition has not been provided as the impact was not considered material.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The following describes our derivative classifications: Fair Value Hedges. Includes derivative contracts we hold to hedge the risk of changes in the price of our inventory. Cash Flow Hedges. Includes derivative contracts we execute to mitigate the risk of price and interest rate volatility in forecasted transactions. Non-designated Derivatives. Includes derivatives we primarily transact to mitigate the risk of market price fluctuations in swaps or futures contracts, as well as certain forward fixed price purchase and sale contracts to hedge the risk of currency rate fluctuations and for portfolio optimization. In March 2020, we entered into a $300 million , one-month LIBOR, floating-for-fixed non-amortizing interest rate swap contract ("IR Swap") with a maturity date in March 2025. The IR Swap was designated as a cash flow hedge to mitigate potential adverse changes in interest rates related to certain variable rate debt obligations. The IR Swap is measured at fair value each reporting period and changes in fair value are recorded to Accumulated other comprehensive income or loss (AOCI) on our Consolidated Balance Sheets.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The carrying amounts of cash and cash equivalents, net accounts receivable, accounts payable and accrued expenses and other current liabilities approximate fair value based on their short-term maturities. The carrying values of our debt and notes receivable approximate fair value since these instruments bear interest either at variable rates or fixed rates which are not significantly different from market rates. Based on the fair value hierarchy, our total debt of $1.2 billion and $0.6 billion as of March 31, 2020 and December 31, 2019 , respectively, and our notes receivable of $24.5 million and $21.0 million as of March 31, 2020 and December 31, 2019 , respectively, are categorized as Level 2. The following tables present information about our gross assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2020 and December 31, 2019 (in millions): Fair Value Measurements as of March 31, 2020 Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Assets: Commodities contracts $ 930.1 $ 426.2 $ 44.6 $ 1,400.9 Foreign currency contracts — 27.1 — 27.1 Interest rate contract — — — — Cash surrender value of life insurance — 9.0 — 9.0 Total assets at fair value $ 930.1 $ 462.3 $ 44.6 $ 1,437.0 Liabilities: Commodities contracts $ 965.4 $ 306.5 $ 11.0 $ 1,282.8 Foreign currency contracts — 9.8 — 9.8 Interest rate contract $ — $ 2.0 $ — $ 2.0 Total liabilities at fair value $ 965.4 $ 318.3 $ 11.0 $ 1,294.6 Fair Value Measurements as of December 31, 2019 Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Assets: Commodities contracts $ 148.3 $ 100.0 $ 10.7 $ 259.0 Foreign currency contracts — 2.0 — 2.0 Cash surrender value of life insurance — 9.4 — 9.4 Total assets at fair value $ 148.3 $ 111.4 $ 10.7 $ 270.4 Liabilities: Commodities contracts $ 177.6 $ 69.3 $ 8.1 $ 255.0 Foreign currency contracts — 11.6 — 11.6 Total liabilities at fair value $ 177.6 $ 80.9 $ 8.1 $ 266.6 There were no transfers between Level 1 and Level 2 during the periods presented. Additionally, the fair values of our commodity contracts measured using Level 3 inputs were not material at March 31, 2020 and December 31, 2019 , respectively. For our derivative contracts, we may enter into master netting, collateral and offset agreements with counterparties. These agreements provide us the ability to offset a counterparty’s rights and obligations, request additional collateral when necessary or liquidate the collateral in the event of counterparty default. We net the fair value of cash collateral paid or received against fair value amounts recognized for net derivative positions executed with the same counterparty under the same master netting or offset agreement. The following tables summarize those derivative balances subject to the right of offset as presented on our Consolidated Balance Sheets as of March 31, 2020 and December 31, 2019 . We have elected to offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements when a legal right of offset exists.

Concentration of Credit Risk Our individual over-the-counter ("OTC") counterparty exposure is managed within predetermined credit limits and includes the use of cash-call margins when appropriate, thereby reducing the risk of significant nonperformance. At March 31, 2020 , one of our counterparties with an exposure amount of $28.2 million represented over 10% of our credit exposure to OTC derivative counterparties.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our income tax provision for the periods presented and the respective effective income tax rates for such periods are as follows (in millions, except for income tax rates): For the Three Months Ended March 31, 2020 2019 Income tax provision $ 16.0 $ 14.0 Effective income tax rate 27.7 % 27.3 % Our provision for income taxes for the three months ended March 31, 2020 was $16.0 million , resulting in an effective income tax rate of 27.7% . The provision includes a net discrete tax expense of $1.0 million for the period. Without the $1.0 million in discrete items, the effective income tax rate would have been 25.9% . Our provision for income taxes for the three months ended March 31, 2019 was $14.0 million resulting in an effective tax rate of 27.3% . The provision includes a net discrete income tax benefit of $2.8 million for the period. Without the $2.8 million in discrete items, the effective income tax rate would have been 32.8% . Our income tax concession in Singapore which reduces the income tax rate on qualified sales and derivative gains and losses decreased foreign income taxes by $2.0 million and $0.9 million for the three months ended March 31, 2020 and 2019, respectively. The impact of the income tax concession on basic earnings per common share was $0.03 and $0.01 for the three months ended March 31, 2020 and 2019, respectively. On a diluted earnings per common share basis, the impact was $0.03 and $0.01 for the three months ended March 31, 2020 and 2019, respectively. Our provision for income taxes for the three months ended March 31, 2020 and 2019 was calculated based on the estimated annual effective income tax rate for the 2020 and 2019 fiscal years. The actual effective income tax rate for the 2020 fiscal year may be materially different as a result of differences between estimated versus actual results and the geographic tax jurisdictions in which the results are earned. We have various tax returns under examination both in the U.S. and foreign jurisdictions. The most significant of these are in Denmark for the 2013 - 2015 tax years, South Korea for the 2011 - 2014 tax years, and the U.S. for the 2017 - 2018 tax years. In 2018, one of our subsidiaries in Denmark received an audit inquiry from the Danish tax authorities regarding transfer pricing and other related matters for the tax years 2013-2015. In Q2 2019, it received a proposed income adjustment of approximately $1.7 million related to the 2013 tax year and on April 30, 2020, it received a proposed income adjustment of approximately $5.2 million related to the 2014 tax year. We are currently responding to the proposed income adjustments and other information requests from the Danish tax authorities. In 2017, the Korean Branch of one of our subsidiaries received income tax assessment notices for $9.3 million (KRW 11.3 billion ) from the South Korea tax authorities. We believe that these assessments are without merit and are currently appealing the actions. On March 11, 2020, the U.S. Internal Revenue Service began the audit of our 2017 and 2018 tax years, and we are responding to their information requests. An unfavorable resolution of one or more of the above matters could have a material adverse effect on our result of operations or cash flows in the quarter or year in which the adjustments are recorded, or the tax is due or paid. As examinations are still in process or have not yet reached the final stages of the appeals process, the timing of the ultimate resolution or payments that may be required cannot be determined at this time.

Revenue from Contracts with Cus

Revenue from Contracts with Customers	3 Months Ended
	Mar. 31, 2020
Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Our contracts with customers primarily require us to deliver fuel and fuel-related products, while other arrangements require us to complete agreed-upon services. Revenue from the sale of fuel is recognized when our customers obtain control of the fuel, which is typically upon delivery of each promised gallon or barrel to an agreed-upon delivery point. We generally recognize revenue for services provided over the contract period when services have been performed based on our right to invoice for those services. Our contracts may contain fixed or variable pricing (such as market or index-based pricing) or some combination of those. Within our land and aviation segments, contracts with customers may include multi-year sales contracts, which are priced at market-based indices and require minimum volume purchase commitments from our customers. The consideration expected from these contracts is considered variable due to the market-based pricing and the variability is not resolved until delivery is made to our customers. We have elected to apply the optional exemption from estimating and disclosing the variable consideration from our remaining performance obligations under these contracts. We also have fixed price fuel and fuel-related product sale contracts with a contract term of less than one year (typically one month). For these contracts, we apply the optional exemption to not disclose the amount of transaction price allocated to remaining performance obligations. We also apply this exemption to those contracts in which the right to consideration corresponds directly with the value to the customer of the entity's performance to date. In limited cases, we may have multi-period fixed price contracts. Because our long-term supply arrangements that exceed one year are typically based on market index prices as previously discussed, the transaction price associated with remaining performance obligations under multi-year fixed price fuel sale contracts is not significant. The following table presents our revenues from contracts with customers disaggregated by major geographic areas we conduct business in for the three months ended March 31, 2020 and 2019 (in millions): For the Three Months Ended March 31, 2020 2019 Aviation $ 252.3 $ 364.4 Land 4.7 4.8 Marine 924.6 708.9 Asia Pacific $ 1,181.7 $ 1,078.1 Aviation $ 638.9 $ 719.1 Land 618.2 640.5 Marine 611.2 654.7 EMEA $ 1,868.3 $ 2,014.3 Aviation $ 560.7 $ 545.7 Land 130.4 138.9 Marine 233.3 191.4 LATAM $ 924.5 $ 876.0 Aviation $ 2,126.8 $ 2,648.0 Land 1,329.4 1,634.4 Marine 342.1 334.5 North America $ 3,798.3 $ 4,616.9 Other revenues (excluded from ASC 606)* $ 242.3 $ 93.5 $ 8,015.2 $ 8,678.8 * Includes revenue from leases and other transactions that we account for under separate guidance. The nature of the receivables related to revenue from contracts with customers and other revenue are substantially similar, given that they are generated from transactions with the same type of counterparties (e.g., separate fuel sales and storage lease with the same counterparty) and are entered into considering the same credit approval and monitoring procedures for all customers. As such, we believe the risk associated with the cash flows from the different types of receivables is not meaningful to separately disaggregate the accounts receivable balance presented on our Consolidated Balance Sheet. Furthermore, as of March 31, 2020 and December 31, 2019 , the contract assets and contract liabilities recognized by the Company were not material.

Segment Reporting [Abstract]
Business Segments	Business Segments We operate in three reportable segments consisting of aviation, land and marine. Corporate expenses are allocated to the segments based on usage, where possible, or on other factors according to the nature of the activity. Our operating segments are determined based on the different markets in which we provide products and services, which are defined primarily by the customers and the products and services provided to those customers. Accordingly, our aviation, land and marine segments are organized based on the specific markets their functional business components serve, which are primarily businesses and governmental customers operating in those respective markets. In our aviation segment, we offer fuel and related products and services to major commercial airlines, second and third-tier airlines, cargo carriers, regional and low cost carriers, airports, fixed based operators, corporate fleets, fractional operators, private aircraft. In addition, we supply products and services to U.S. and foreign government, intergovernmental and military customers, such as the North Atlantic Treaty Organization (NATO) and the U.S. Defense Logistics Agency. In our land segment, we offer fuel, lubricants, power and natural gas solutions through World Kinect, our energy management services platform, and related products and services to customers including petroleum distributors operating in the land transportation market, retail petroleum operators, and industrial, commercial, residential and government customers. Our marine segment product and service offerings include fuel, lubricants and related products and services to a broad base of customers, including international container and tanker fleets, commercial cruise lines, yachts and time charter operators, offshore rig owners and operators, the U.S. and foreign governments as well as other fuel suppliers. Within each of our segments, we may enter into derivative contracts to mitigate the risk of market price fluctuations and also to offer our customers fuel pricing alternatives to meet their needs. Information concerning our revenue, gross profit and income from operations by segment is as follows for the three months ended March 31, 2020 and 2019 (in millions): For the Three Months Ended March 31, Revenue: 2020 2019 Aviation segment $ 3,764.1 $ 4,252.7 Land segment 2,106.0 2,493.6 Marine segment 2,145.0 1,932.5 $ 8,015.2 $ 8,678.8 Gross profit: Aviation segment $ 93.2 $ 114.3 Land segment 106.3 101.5 Marine segment 59.3 35.2 $ 258.7 $ 251.1 Income from operations: Aviation segment $ 29.1 $ 55.6 Land segment 25.7 21.0 Marine segment 33.9 13.5 88.6 90.1 Corporate overhead - unallocated (17.8 ) (19.7 ) $ 70.8 $ 70.4 Information concerning our accounts receivable, net and total assets by segment is as follows as of March 31, 2020 and December 31, 2019 (in millions): As of March 31, December 31 2020 2019 Accounts receivable, net: Aviation segment, net of allowance for credit losses of $22.2 and $14.6 as of March 31, 2020 and December 31, 2019, respectively $ 606.5 $ 1,098.2 Land segment, net of allowance for credit losses of $8.3 and $2.8 as of March 31, 2020 and December 31, 2019, respectively 728.1 863.2 Marine segment, net of allowance for credit losses of $22.4 and $18.0 as of March 31, 2020 and December 31, 2019, respectively 650.5 930.5 $ 1,985.1 $ 2,891.9 Total assets: Aviation segment $ 2,215.2 $ 2,416.5 Land segment 2,115.9 2,089.4 Marine segment 1,059.3 1,189.7 Corporate 108.5 296.8 $ 5,498.9 $ 5,992.4 During each of the periods presented on the Consolidated Statements of Income and Comprehensive Income, none of our customers accounted for more than 10% of total consolidated revenue. Sales to government customers, which principally consist of sales to NATO in support of military operations in Afghanistan, have accounted for a material portion of our profitability in recent years. The profitability associated with our government business can be significantly impacted by supply disruptions, border closures, road blockages, hostility-related product losses, inventory shortages and other logistical difficulties that can arise when sourcing and delivering fuel in areas that are actively engaged in war or other military conflicts. Our sales to government customers may fluctuate significantly from time to time as a result of the foregoing factors, as well as the level of troop deployments and related activity in a particular region or area or the commencement, extension, renewal or completion of existing and new government contracts.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Tax Matters From time to time, we are under review by various domestic and foreign tax authorities with regard to indirect tax matters and are involved in various challenges and litigation in a number of countries, including, in particular, Brazil and South Korea, where the amounts under controversy may be material. We believe that these assessments are without merit and are currently appealing the actions. During the quarter ended December 31, 2016, the Korean branch (“WFSK”) of one of our subsidiaries received assessments of approximately $9.3 million (KRW 11.3 billion ) and during the quarter ended June 30, 2017, an assessment for an additional $16.5 million (KRW 20.1 billion ) from the regional tax authorities of Seoul, South Korea (“SRTO”). The assessments primarily consist of fines and penalties for allegedly failing to issue Value Added Tax ("VAT") invoices and report certain transactions during the period 2011-2014. These assessments do not involve failure to pay or collect VAT. We believe that these assessments are without merit and are currently appealing the actions. We are also involved in a number of tax disputes with federal, state and municipal tax authorities in Brazil, relating primarily to a VAT tax known as "ICMS". These disputes are at various stages of the legal process, including the administrative review phase and the collection action phase, and include assessments of fixed amounts of principal and penalties, plus interest. One of our Brazilian subsidiaries is currently appealing an assessment of approximately $9.5 million (BRL 49.1 million ) from the Brazilian tax authorities relating to the ICMS rate used for certain transactions. The assessment primarily consists of interest and penalties. We believe that the assessment is without merit and are pursuing our remedies in the judicial court system. When we deem it appropriate and the amounts are reasonably estimable, we establish reserves for potential adjustments to our provision for the accrual of indirect taxes that may result from examinations or other actions by tax authorities. If events occur which indicate payment of these amounts is unnecessary, the reversal of the liabilities would result in the recognition of benefits in the period we determine the liabilities are no longer necessary. If our estimates of any of our federal, state, and foreign indirect tax liabilities are less than the ultimate assessment, it could result in a further charge to expense. Except with respect to the matters described above, we believe that the final outcome of any pending examinations, agreements, administrative or judicial proceedings will not have a material effect on our results of operations or cash flows. Other Matters We are also a party to various claims, complaints and proceedings arising in the ordinary course of our business including, but not limited to, environmental claims, commercial and governmental contract claims, such as property damage, demurrage, personal injury, billing and fuel quality claims, as well as bankruptcy preference claims and tax and administrative claims. We have established loss provisions for these ordinary course claims as well as other matters in which losses are probable and can be reasonably estimated. As of March 31, 2020 , we had recorded certain reserves which were not material. For those matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which an exposure to loss in excess of the amount accrued is reasonably possible, we believe that such losses will not have a material adverse effect on our Consolidated Financial Statements. However, any adverse resolution of one or more such claims, complaints or proceedings during a particular period could have a material adverse effect on our Consolidated Financial Statements or disclosures for that period. Our estimates regarding potential losses and materiality are based on our judgment and assessment of the claims utilizing currently available information. Although we will continue to reassess our reserves and estimates based on future developments, our objective assessment of the legal merits of such claims may not always be predictive of the outcome and actual results may vary from our current estimates.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring As a result of continued review of our land business and changes in the overall economic landscape for all reportable segments as result of the COVID-19 pandemic, we are implementing a restructuring initiative focused on further streamlining our operations and sharpening our deployment of resources in 2020. We are working to further define the plan for the restructuring during the second quarter of 2020. For the three months ended March 31, 2020 , we incurred $1.7 million in restructuring costs, comprised principally of certain employee-related costs included in Compensation and employee benefits in our Consolidated Statements of Income and Comprehensive Income. Our accrued restructuring charges as of March 31, 2020 are included in Accrued expenses and other current liabilities on our Consolidated Balance Sheet. The following table provides a summary of our restructuring activities during the three months ended March 31, 2020 (in millions): Aviation Land Marine Corporate Consolidated Balance as of December 31, 2019 $ 0.5 $ 7.5 $ 1.3 $ 0.2 $ 9.5 Severance costs 0.1 1.3 0.1 0.2 1.7 Payments (0.4 ) (2.7 ) (0.8 ) (0.3 ) (4.2 ) Restructuring charges as of March 31, 2020 $ 0.2 $ 6.1 $ 0.7 $ 0.1 $ 7.0

Accounting Policies [Abstract]
Basis of Presentation	World Fuel Services Corporation (the “Company”) was incorporated in Florida in July 1984 and along with its consolidated subsidiaries is referred to collectively in this Quarterly Report on Form 10‑Q (“10-Q Report”) as “World Fuel,” “we,” “our” and “us.” We are a leading global fuel services company, principally engaged in the distribution of fuel and related products and services in the aviation, marine and land transportation industries. In recent years, we have expanded our product and service offerings to include energy advisory services and supply fulfillment with respect to natural gas and power and transaction and payment management solutions to commercial and industrial customers. Our intention is to become a leading global energy management company offering a full suite of energy advisory, management and fulfillment services, technology solutions as well as sustainability products and services across the energy product spectrum. We also offer payment management solutions to commercial and industrial customers, principally in the aviation, land and marine transportation industries. We will continue to focus on enhancing the portfolio of products and services we provide based on changes in customer demand, including sustainability offerings and renewable fuel products. We prepared the Consolidated Financial Statements following the requirements of the United States (“U.S.”) Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by accounting principles generally accepted in the U.S. (“U.S. GAAP”) can be condensed or omitted.
Use of Estimates	Certain amounts in the Consolidated Financial Statements and accompanying notes may not add due to rounding. All percentages have been calculated using unrounded amounts
Adoption of New Accounting Standard and Accounting Standards Issued but Not Yet Adopted	Adoption of New Accounting Standards We included below a description of recent new accounting standards or accounting standards updates that had an impact on the Company’s consolidated financial statements. New accounting standards or accounting standards updates not listed below were assessed and determined to be either not applicable or did not have a material impact on the Company’s consolidated financial statements or processes. Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. In June 2016, Accounting Standards Update ("ASU") 2016-13 was issued, which replaced the incurred loss impairment model with a model that reflects expected credit losses over the lifetime of the asset and requires consideration of a broader range of reasonable and supportable information to determine credit loss estimates. The guidance in this update, including the subsequent related codification amendments, changed how entities account for credit impairment from trade and other receivables, net investments arising from sales-type and direct financing leases, debt securities, purchased-credit impaired financial assets and other instruments in addition to loans. For receivables and certain other instruments that are not measured at fair value, entities are required to estimate expected credit losses. Under the expected loss model, an entity recognizes a loss upon initial recognition of the asset that reflects all future events that could lead to a loss being realized, regardless of whether it is probable that the future event will occur. The Company adopted ASU 2016-13, including the related codification amendments, in the first quarter of 2020 utilizing the modified retrospective transition method and applying the transition provisions at the effective date. The Company implemented changes to business processes and internal controls that support the new standard. As of the date of implementation on January 1, 2020, the Company recognized $11.1 million as a reduction to the opening retained earnings balance. The main drivers of the consolidated impact at transition are related to the inclusion of future economic conditions, the exclusion of freestanding credit enhancements when estimating the expected credit loss and estimating the lifetime credit losses of notes receivable. Accounting Standards Issued but Not Yet Adopted There have been no recently issued accounting standards not yet adopted by us which are expected, upon adoption, to have a material impact on the Company’s Consolidated Financial Statements or processes.
Revenue from Contracts with Customers	Our contracts with customers primarily require us to deliver fuel and fuel-related products, while other arrangements require us to complete agreed-upon services. Revenue from the sale of fuel is recognized when our customers obtain control of the fuel, which is typically upon delivery of each promised gallon or barrel to an agreed-upon delivery point. We generally recognize revenue for services provided over the contract period when services have been performed based on our right to invoice for those services. Our contracts may contain fixed or variable pricing (such as market or index-based pricing) or some combination of those. Within our land and aviation segments, contracts with customers may include multi-year sales contracts, which are priced at market-based indices and require minimum volume purchase commitments from our customers. The consideration expected from these contracts is considered variable due to the market-based pricing and the variability is not resolved until delivery is made to our customers. We have elected to apply the optional exemption from estimating and disclosing the variable consideration from our remaining performance obligations under these contracts. We also have fixed price fuel and fuel-related product sale contracts with a contract term of less than one year (typically one month). For these contracts, we apply the optional exemption to not disclose the amount of transaction price allocated to remaining performance obligations. We also apply this exemption to those contracts in which the right to consideration corresponds directly with the value to the customer of the entity's performance to date. In limited cases, we may have multi-period fixed price contracts. Because our long-term supply arrangements that exceed one year are typically based on market index prices as previously discussed, the transaction price associated with remaining performance obligations under multi-year fixed price fuel sale contracts is not significant.
