	Notes to the Consolidated Financial Statements
	(Unaudited)
	1.Significant Accounting Policies
	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 2014 10‑K Report.
	Goodwill
	During the first three months of 2015, we increased land segment goodwill by $1.0 million as a result of a reduction in identifiable intangible assets and an increase in property and equipment and reduced aviation segment goodwill by $1.9 million as a result of a reduction in purchase price based on our ongoing fair value assessment of certain of our 2014 acquisitions.  Additionally, we had goodwill decreases of $5.9 million, $2.6 million and $0.8 million as a result of foreign currency translation adjustments of our non-U.S. dollar functional currency subsidiaries in our land, aviation and marine segments, respectively.
	Recent Accounting Pronouncements
	Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. In April 2015, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. This update is effective at the beginning of our 2016 fiscal year.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Consolidation: Amendments to the Consolidation Analysis.  In February 2015, the FASB issued an ASU which is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures. This update is effective at the beginning of our 2016 fiscal year.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Income Statement-Extraordinary and Unusual Items: Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. In January 2015, the FASB issued an ASU which eliminates from generally accepted accounting principles in the United States the concept of extraordinary items. This update is effective at the beginning of our 2016 fiscal year.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Derivatives and Hedging: Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity. In November 2014, the FASB issued an ASU which clarifies how current generally accepted accounting principles in the United States should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share.  This update is effective at the beginning of our 2016 fiscal year.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Presentation of Financial Statements-Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.  In August 2014, the FASB issued an ASU which requires management of the Company to evaluate whether there is substantial doubt about the Company’s ability to continue as a going concern. This update is effective at the beginning of our 2017 fiscal year. We do not believe the adoption of this new guidance will have an impact on our financial statement disclosures.
	Compensation-Stock Compensation. Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. In June 2014, the FASB issued an ASU which includes guidance that requires a performance target that affects vesting and that could be achieved after the requisite service period to be treated as a performance condition. This update is effective at the beginning of our 2016 fiscal year. We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.  In June 2014, the FASB issued an ASU which changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. It also requires additional disclosures about repurchase agreements and other similar transactions. This update became effective at the beginning of our 2015 fiscal year.  The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures.
	Revenue from Contracts with Customers.  In May 2014, the FASB issued an ASU which provides guidance for revenue recognition for any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. The ASU will replace most existing revenue recognition guidance in generally accepted accounting principles in the United States when it becomes effective. This update is effective at the beginning of our 2017 fiscal year. We are currently evaluating whether the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.  In April 2014, the FASB issued an ASU which changes the criteria for reporting discontinued operations and enhances disclosures in this area. It also addresses sources of confusion and inconsistent application related to financial reporting of discontinued operations guidance. This update became effective at the beginning of our 2015 fiscal year.  The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures.
	Reclassifications
	Certain amounts in prior periods have been reclassified to conform to the current period’s presentation.

	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 $700.8 million and $689.9 million as of March 31, 2015 and December 31, 2014, respectively, and our notes receivable of $8.2 million and $7.0 million as of March 31, 2015 and December 31, 2014, 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 March 31, 2015, we had $257.4 million of cash collateral deposits held by financial counterparties, of which $207.1 million have been offset against the total amount of commodity fair value liabilities in the above table and the remaining $50.3 million is included in other current assets in the accompanying consolidated balance sheets.  In addition, as of March 31, 2015, we have offset $32.0 million of cash collateral deposits received from customers against the total amount of commodity fair value assets in the above table.  As of December 31, 2014, we had $301.0 million of cash collateral deposits held by financial counterparties, of which $274.3 million have been offset against the total amount of commodity fair value liabilities in the above table and the remaining $26.7 million is included in other current assets in the accompanying consolidated balance sheets. In addition, as of December 31, 2014, we have offset $46.7 million of cash collateral deposits received from customers against the total amount of commodity fair value assets in the above table.
	The following table presents information about our assets and liabilities that are measured at fair value on a recurring basis that utilized Level 3 inputs for the periods presented (in millions):

	Liabilities:
	Commodity contracts	$	1.3	$	0.5	$	0.5	$	0.3	$	0.8	Cost of revenue
	The nature of inputs that are considered Level 3 are modeled inputs. Commodity contracts categorized in Level 3 are due to the significance of the unobservable model inputs to their respective fair values. The unobservable model inputs, such as basis differentials, are based on the difference between the historical prices of our prior transactions and the underlying observable data as well as certain risk related to non-performance.  The effect on our income before income taxes of a 10% change in the model input for non-performance risk would not be significant. There were no transfers between Level 1, 2 or 3 during the periods presented.

	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 March 31, 2015, our derivative instruments, at their respective fair value positions were as follows (in millions, 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. As of March 31, 2015, the net liability position for such contracts is $73.3 million, the collateral posted is $57.5 million and the amount of assets required to be posted and/or to settle the positions should a credit-risk contingent feature be triggered is $15.8 million.  As of December 31, 2014, the net liability position for such contracts is $111.7 million, the collateral posted is $89.4 million and the amount of assets required to be posted and/or to settle the positions should a credit-risk contingent feature be triggered is $22.3 million.

	Legal Matters
	Lac-Megantic, Quebec
	As previously disclosed in “Note 7 — Commitments and Contingencies” in the Notes to the Consolidated Financial Statements included in our 2014 10-K Report, various lawsuits have been filed against us and other third parties related to the July 2013 train derailment in Lac-Mégantic, Quebec.  The Trustee for Montreal, Maine and Atlantic Railway’s (“MMA”) U.S. bankruptcy estate (the “Trustee”) and the monitor in MMA’s Canadian bankruptcy continue to discuss a global settlement with various parties, including us, and such discussions are ongoing.  Although amounts to settle have been proffered to us in the course of discussions, to date such offers have been informal, not fully defined, or varied significantly in terms of scope and substance.  In addition, the settlement discussions have involved multiple parties whose support for the various offers has been uncertain.  Accordingly, we are unable to provide information at this time that we believe would enable investors to reasonably assess the significance of these offers or their bearing on the probability, timing or range of any potential settlement.  While we continue to actively discuss a potential settlement to resolve the outstanding claims against us, the settlement discussions may not ultimately result in an agreement.
	The Trustee and the Canadian debtor have each filed proposed bankruptcy plans (in the U.S. and Canada, respectively) that seek to implement settlements reached to date with other parties. Prior to becoming effective, the proposed bankruptcy plans will need to be approved by the requisite creditors in both the U.S. and Canadian bankruptcies, such as plaintiffs in the class action and the Quebec provincial government.  Thereafter, if so approved, the plans will be submitted to the respective bankruptcy courts for approval.  The bankruptcy plans may also be challenged by third parties objecting to the plans and, therefore, approval of the plans and the related timing is uncertain.  The bankruptcy plans may be amended at any time prior to their effective date to include additional settlements.  For additional information regarding legal proceedings related to the train derailment, see our 2014 10-K Report and Part II — Item 1 of this 10-Q Report.
	In light of the facts, circumstances and other information available to us at this time, we are currently unable to determine the probability of loss, or reasonably estimate a range of potential losses related to the proceedings arising from the train derailment. Accordingly, we have not made any provision for these potential losses in our consolidated financial statements.  However, based on estimated losses related to the value of the tank cars involved in the incident, as well as legal and other costs incurred in connection with the incident, which we believe are probable and for which a reasonable estimate can be made, we have recorded total liabilities of $42.2 million.  We believe that a substantial portion of these liabilities are covered by insurance and have recorded total receivables of $39.1 million. As of March 31, 2015, the remaining unpaid liabilities of $16.3 million are included primarily in accrued expenses and other current liabilities and the remaining uncollected receivable of $29.4 million is included in other current assets in the accompanying consolidated balance sheets.
	Other Matters
	In connection with a theft of fuel product valued at approximately $18.0 million, we recorded an insurance receivable for the full amount of the loss, which is included in other current assets in the accompanying consolidated balance sheets. On July 31, 2014, our insurer, AGCS Marine Insurance Company (“AGCS”), filed a declaratory judgment action against us in the United States District Court for the Southern District of New York seeking a court ruling that the loss is not covered under our policy.  During the quarter ended December 31, 2014, we filed an answer to the AGCS complaint and counterclaims against AGCS for declaratory judgment and breach of contract seeking a court ruling that the loss is covered under the policy, an award of damages equal to the full amount of our loss plus interest, as well as fees and costs.  We believe AGCS’ position is without merit and we intend to vigorously pursue our rights.  However, due to the complexities and uncertainties inherent in litigation, we can provide no assurance that we will recover the full amount of the loss.
	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 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, 2015, 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 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.
	Termination of Employment Agreement
	On March 13, 2015, we agreed with Mr. Michael S. Clementi that he would retire from his position as Aviation Segment President, effective March 16, 2015.  In connection with the termination of his employment agreement, we recorded a charge totaling $3.8 million in March 2015, which included non-cash expenses of $0.8 million related to previously awarded stock compensation. As of March 31, 2015, $1.0 million of the cash portion of the termination of the employment agreement charge was included in accrued expenses and other current liabilities and $2.0 million was included in other long-term liabilities in the accompanying consolidated balance sheets.

	Our provision for income taxes for each of the three-month periods ended March 31, 2015 and 2014 was calculated based on the estimated annual effective income tax rate for the full 2015 and 2014 fiscal years. The actual effective income tax rate for the full 2015 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 operated under a special income tax concession in Singapore which began January 1, 2008.  Our current five year special income tax concession was effective January 1, 2013.  The special income tax concession is conditional upon our meeting of certain employment and investment thresholds which, if not met in accordance with our agreement, may eliminate the benefit beginning with the first year in which the conditions are not satisfied.  The income tax concession reduces the income tax rate on qualified sales and the impact of this income tax concession decreased foreign income taxes by $2.3 million and $ 1.9 million for the three months ended March 31, 2015 and 2014, respectively.  The impact of the income tax concession on basic earnings per common share was $0.03 for the three months ended March 31, 2015 and 2014, respectively.  On a diluted earnings per common share basis, the impact was $0.03 for the three months ended March 31, 2015 and 2014, respectively.

Recent Accounting Pronouncements	Recent Accounting Pronouncements
	Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. In April 2015, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. This update is effective at the beginning of our 2016 fiscal year.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Consolidation: Amendments to the Consolidation Analysis.  In February 2015, the FASB issued an ASU which is intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures. This update is effective at the beginning of our 2016 fiscal year.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Income Statement-Extraordinary and Unusual Items: Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. In January 2015, the FASB issued an ASU which eliminates from generally accepted accounting principles in the United States the concept of extraordinary items. This update is effective at the beginning of our 2016 fiscal year.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Derivatives and Hedging: Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity. In November 2014, the FASB issued an ASU which clarifies how current generally accepted accounting principles in the United States should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share.  This update is effective at the beginning of our 2016 fiscal year.  We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Presentation of Financial Statements-Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.  In August 2014, the FASB issued an ASU which requires management of the Company to evaluate whether there is substantial doubt about the Company’s ability to continue as a going concern. This update is effective at the beginning of our 2017 fiscal year. We do not believe the adoption of this new guidance will have an impact on our financial statement disclosures.
	Compensation-Stock Compensation. Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. In June 2014, the FASB issued an ASU which includes guidance that requires a performance target that affects vesting and that could be achieved after the requisite service period to be treated as a performance condition. This update is effective at the beginning of our 2016 fiscal year. We do not believe the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Transfers and Servicing: Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures.  In June 2014, the FASB issued an ASU which changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. It also requires additional disclosures about repurchase agreements and other similar transactions. This update became effective at the beginning of our 2015 fiscal year.  The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures.
	Revenue from Contracts with Customers.  In May 2014, the FASB issued an ASU which provides guidance for revenue recognition for any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. The ASU will replace most existing revenue recognition guidance in generally accepted accounting principles in the United States when it becomes effective. This update is effective at the beginning of our 2017 fiscal year. We are currently evaluating whether the adoption of this new guidance will have a significant impact on our consolidated financial statements and disclosures.
	Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.  In April 2014, the FASB issued an ASU which changes the criteria for reporting discontinued operations and enhances disclosures in this area. It also addresses sources of confusion and inconsistent application related to financial reporting of discontinued operations guidance. This update became effective at the beginning of our 2015 fiscal year.  The adoption of this ASU did not have a significant impact on our consolidated financial statements and disclosures.
