Significant Accounting Policies
Significant Accounting Policies	1.              Significant Accounting Policies
	Except as updated below, the significant accounting policies we use for quarterly financial reporting are the same as those disclosed in Note 1 of the “Notes to the Consolidated Financial Statements” included in our 2012 10-K Report.
	Basis of Consolidation
	The accompanying consolidated financial statements and related notes include the accounts of our wholly-owned and majority-owned subsidiaries and joint ventures where we exercise operational control or have a primary benefit of its profits. All significant intercompany accounts, transactions and profits are eliminated upon consolidation.
	Reclassifications
	Certain amounts in prior periods have been reclassified to conform to the current period’s presentation.
	Goodwill
	During the first nine months of 2013, we recorded goodwill of $9.6 million in our land segment in connection with two acquisitions completed during the period, which were not material individually or in the aggregate. In addition, based on our ongoing fair value assessment of certain of our 2012 acquisitions, we recorded a $2.0 million reduction in goodwill within our land segment principally due to a $3.3 million increase in identifiable intangible assets, partially offset by a $0.9 million decrease in other acquired assets and a $0.4 million increase in assumed liabilities. Additionally, we reclassified $6.5 million in goodwill from our land segment to our aviation segment.  We had additional goodwill reductions of $0.5 million and $0.3 million as a result of foreign currency translation adjustments of our non-U.S. dollar functional currency subsidiaries in our marine and aviation segments, respectively.
	Recent Accounting Pronouncements
	Presentation of an Unrecognized Tax Benefit When a Net Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.  In July 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update (“ASU”) on the presentation of an unrecognized tax benefit when a net operating loss carryforward exists. Under this guidance, an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward.  This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently evaluating whether the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes.  In July 2013, the FASB issued an ASU which includes amendments permitting the Fed Funds Effective Swap Rate to be used as a U.S. benchmark interest rate for hedge accounting purposes, in addition to U.S. Government and London Interbank Offered Rate.  The amendments also remove the restriction on using different benchmark rates for similar hedges.  This update is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013.  The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures.
	Foreign Currency Matters Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Foreign Subsidiaries.  In March 2013, the FASB issued an ASU aimed at resolving the diversity in practice of accounting for the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. In addition, the amendments in this ASU resolve the diversity in practice for the treatment of business combinations achieved in stages (sometimes also referred to as step acquisitions) involving a foreign entity.  This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Disclosure Obligations Resulting from Joint and Several Liability Arrangements.  In February 2013, the FASB issued an ASU clarifying the guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this ASU is fixed at the reporting date, except for obligations addressed within existing guidance in U.S. GAAP.  This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 and will be applied retrospectively.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Disclosure Relating to Amounts Reclassified Out of Accumulated Other Comprehensive Income.  In February 2013, the FASB issued an ASU amending the information that companies will be required to present relating to reclassifications out of accumulated other comprehensive income. The amendments require presentation, either on the face of the financial statements or in the notes, of amounts reclassified out of accumulated other comprehensive income by component and by net income line item.  This update is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012.  The adoption of this ASU resulted in additional derivative disclosures included in Note 2 - Derivatives and did not have a significant impact on our consolidated financial statements.
	Disclosure About Offsetting Assets and Liabilities.  In December 2011, the FASB issued an ASU which requires companies to disclose information about financial instruments that have been offset and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. Companies will be required to provide both net (offset amounts) and gross information in the notes to the financial statements for relevant assets and liabilities that are offset. In January 2013, the FASB issued an ASU clarifying that the requirement to disclose information about financial instruments that have been offset and related arrangements applies only to derivatives, repurchase agreements and reverse purchase agreements, and securities borrowing and lending transactions that are either offset in accordance with specific criteria contained in the FASB Accounting Standards Codification or subject to a master netting arrangement or similar agreement. This update became effective at the beginning of our 2013 fiscal year. The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures.
	Consolidated Statement of Cash Flows for the Six Months ended June 30, 2013
	We identified an incorrect cash flow presentation of $17.7 million related to an acquisition payment that was classified as an operating activity versus an investing activity in the consolidated statement of cash flows for the six months ended June 30, 2013.  We assessed the materiality of this incorrect presentation and concluded it was not material.  As prior period financial information is presented in future SEC filings, we will modify the presentation of the consolidated statement of cash flows to include this revision.

Derivatives

Derivatives	9 Months Ended

Derivatives
Derivatives	2.              Derivatives
	We enter into financial derivative contracts in order to mitigate the risk of market price fluctuations in aviation, marine and land fuel, to offer our customers fuel pricing alternatives to meet their needs and to mitigate the risk of fluctuations in foreign currency exchange rates.  We also enter into proprietary derivative transactions, primarily intended to capitalize on arbitrage opportunities related to basis or time spreads related to fuel products we sell.  We have applied the normal purchase and normal sales exception (“NPNS”), as provided by accounting guidance for derivative instruments and hedging activities, to certain of our physical forward sales and purchase contracts.  While these contracts are considered derivative instruments under the guidance for derivative instruments and hedging activities, they are not recorded at fair value, but rather are recorded in our consolidated financial statements when physical settlement of the contracts occurs.  If it is determined that a transaction designated as NPNS no longer meets the scope of the exception, the fair value of the related contract is recorded as an asset or liability on the consolidated balance sheet and the difference between the fair value and the contract amount is immediately recognized through earnings.
	The following describes our derivative classifications:
	Cash Flow Hedges.  Includes certain of our foreign currency forward contracts we enter into in order to mitigate the risk of currency exchange rate fluctuations.
	Fair Value Hedges.  Includes derivatives we enter into in order to hedge price risk associated with our inventory and certain firm commitments relating to fixed price purchase and sale contracts.
	Non-designated Derivatives.  Includes derivatives we primarily enter into in order to mitigate the risk of market price fluctuations in aviation, marine and land fuel in the form of swaps or futures as well as certain fixed price purchase and sale contracts and proprietary trading. In addition, non-designated derivatives are also entered into to hedge the risk of currency rate fluctuations.
	As of September 30, 2013, our derivative instruments, at their respective fair value positions were as follows (in thousands, except weighted average fixed price and weighted average mark-to-market amount):

We enter into derivative instrument contracts which may require us to periodically post collateral. Certain of these derivative contracts contain clauses that are similar to credit-risk-related contingent features, including material adverse change, general adequate assurance and internal credit review clauses that may require additional collateral to be posted and/or settlement of the instruments in the event an aforementioned clause is triggered.  The triggering events are not a quantifiable measure; rather they are based on good faith and reasonable determination by the counterparty that the triggers have occurred. The net liability position for such contracts, the collateral posted and the amount of assets required to be posted and/or to settle the positions should a contingent feature be triggered is not significant as of September 30, 2013.

	Our provision for income taxes for each of the three-month and nine-month periods ended September 30, 2013 and 2012 were calculated based on the estimated annual effective income tax rate for the full 2013 and 2012 fiscal years.  The provision for income taxes for the three and nine months ended September 30, 2013 includes an adjustment for an income tax benefit of $1.4 million for a discrete item related to a lapse in the statute of limitations.  The provision for income taxes for the nine months ended September 30, 2012 includes an adjustment for an income tax benefit of $3.3 million for a discrete item related to a change in estimate in an uncertain income tax position.  The actual effective income tax rate for the full 2013 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.

	Legal Matters
	Lac-Mégantic, Quebec
	We, on behalf of DPTS Marketing LLC (“DPM”), a crude oil marketing joint venture in which we own a 50% membership interest, purchased crude oil from various producers in the Bakken region of North Dakota.  Dakota Petroleum Transport Solutions, LLC (“DPTS”), a crude oil transloading joint venture in which we also own a 50% membership interest, arranged for the transloading of the crude oil for DPM into tank cars at the joint venture’s facility in New Town, North Dakota.  We leased the tank cars used in the transloading from a number of third party lessors and subleased these tank cars to DPM. We, on behalf of DPM, contracted with Canadian Pacific Railway (“CPR”) for the transportation of the tank cars and the crude oil from New Town, North Dakota to a customer in New Brunswick, Canada.  CPR subcontracted a portion of that route to Montreal, Maine and Atlantic Railway (“MMA”).  On July 6, 2013, the freight train operated by MMA with 72 tank cars carrying approximately 50,000 barrels of the crude oil derailed in Lac-Mégantic, Quebec.  The derailment resulted in significant loss of life, damage to the environment from spilled crude oil and extensive property damage.
	In July and August 2013, we, certain of our subsidiaries, DPM and DPTS, along with a number of third parties, including MMA and certain of its affiliates, as well as several manufacturers and lessors of tank cars, were named as defendants in twenty complaints filed in Illinois.  The complaints generally allege wrongful death and negligence in the failure to provide for the proper and safe transportation of crude oil and seek economic and compensatory damages, as well as costs.  In addition, in July and August 2013, we and certain of our subsidiaries, along with a number of other third parties, including CPR, MMA and certain of its affiliates, as well as several manufacturers and lessors of tank cars, were named as defendants in a motion filed in Quebec Superior Court to authorize the bringing of a class-action lawsuit seeking economic, compensatory and punitive damages, as well as costs.  The motion generally alleges wrongful death and negligence in the failure to provide for the proper and safe transportation of crude oil.
	Furthermore, in July 2013, an order was issued by the government of Quebec against MMA and us, which was modified in August 2013 to add CPR as a party, requiring MMA, CPR and us to recover the spilled crude oil caused by the incident and to otherwise fully remediate the impact of the incident on the environment.  We have filed a contestation of the order and the modified order before the Tribunal administratif du Québec, an administrative body responsible for hearing such proceedings, challenging the legality and validity of the orders on various grounds.
	In addition to these proceedings, we have received demands for indemnification from certain tank car lessors pursuant to our lease agreements with such parties.  We are currently assessing the merits of these demands as well as of the underlying claims for which such indemnification is sought.  Additional claims, lawsuits, proceedings, investigations and orders may be filed, commenced or issued with respect to the incident, which may involve civil claims for damages or governmental investigative, regulatory or enforcement actions against us.
	While we and our joint ventures, DPM and DPTS, maintain insurance to mitigate the costs of environmental releases as well as other results of unexpected events, including loss of life, property damage and defense costs, there can be no guarantee that our insurance will be adequate to cover all liabilities that may be incurred as a result of this incident.
	We are separately evaluating potential claims that we, DPM or DPTS may assert against third parties to recover costs and other liabilities that may be incurred as a result of this incident.  We can provide no guarantee that any such claims, if brought by us, will be successful or, if successful, that the responsible parties will have the financial resources to address any such claims.
	We are currently unable to determine the probability of loss, or reasonably estimate a range of potential losses related to the above proceedings.  Accordingly, we have not made any provision for these potential losses in our consolidated financial statements.
	As of September 30, 2013, we have recorded liabilities of $14.2 million in accrued expenses and other current liabilities in the accompanying consolidated balance sheets based on estimated losses related to the value of the tank cars involved in the incident, as well as legal costs incurred in connection with the incident, which we believe are probable and for which a reasonable estimate can be made.  We believe that a substantial portion of this liability is covered by insurance and have recognized a receivable of $13.4 million, recorded in other current assets, in the accompanying consolidated balance sheets.
	Cathay Pacific Litigation
	Since April 2012, one of our subsidiaries, World Fuel Services (Singapore) Pte Ltd. (“WFSS”) has been involved in litigation with Cathay Pacific Airways Limited (“Cathay”) arising out of the emergency landing of a Cathay aircraft in Hong Kong in 2010, which Cathay alleges was caused by contaminated fuel supplied by WFSS. Cathay claims damages relating to the incident of approximately $34.0 million.  As of September 30, 2013, we have recorded a current liability for the estimated loss with an offsetting receivable from insurance in the accompanying consolidated balance sheets, which amounts were not significant.
	Other Matters
	We are 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, billing and fuel quality claims, as well as bankruptcy preference 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 September 30, 2013, we had recorded certain reserves which were not significant. 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 results of operations or cash flow 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.
	Other Contingencies
	On June 7, 2013, STX Pan OceanCo. Ltd (“STX Pan Ocean”), one of our customers in our marine segment, filed for bankruptcy protection in Korea which was subsequently recognized in the United States on July 12, 2013.  On August 22, 2013, we agreed with STX Pan Ocean and its parent company, STX Corporation (“STX Corp”) to allow the assignment of all of the outstanding receivables owing from STX Corp to STX Pan Ocean.  Concurrently, we entered into a settlement agreement with STX Pan Ocean whereby it agreed to repay the outstanding balance of $20.8 million through a lump sum payment of $3.2 million, with the remaining balance to be paid over the next year.

	The carrying amounts of cash and cash equivalents, accounts receivable, net, accounts payable and accrued expenses and other current liabilities approximate fair value based on the short-term maturities of these instruments.  We believe 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 than market rates.  Based on the fair value hierarchy, our debt of $458.6 million and $380.3 million as of September 30, 2013 and December 31, 2012, respectively, and our notes receivable of $9.5 million and $12.7 million as of September 30, 2013 and December 31, 2012, respectively, are categorized in Level 3.

	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 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.
	As of September 30, 2013, we had $3.1 million of cash collateral deposits held by financial counterparties included in other current assets in the accompanying consolidated balance sheets.  Additionally, as of September 30, 2013, we have offset $0.3 million of cash collateral received from customers against the total amount of commodity fair value assets in the above table.  As of December 31, 2012, we had $22.9 million of cash collateral deposits held by financial counterparties included in other current assets in the accompanying consolidated balance sheets.  Additionally, as of December 31, 2012, we had offset $6.6 million of cash collateral received from customers against the total amount of commodity fair value assets in the above table.
