Commitments and Contingencies	Commitments and Contingencies Legal 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 (“District Court”) seeking a court ruling indicating that the loss is not covered under our policy. On May 17, 2016, the District Court entered an Order granting summary judgment in our favor demur holding that the loss is covered under the AGCS policy. Final judgment in the case has not yet been entered however on August 18, 2016, the District Court heard oral argument on the issue of damages and pre-judgment interest, which issues are pending before the court. On June 14, 2016, AGCS filed with the District Court a Notice of Appeal whereby it sought to appeal the Order granting summary judgment to the United States Court of Appeals for the Second Circuit ("Appellate Court"), after which we filed a Notice of Cross-Appeal. On August 3, 2016, the Appellate Court issued an Order staying AGCS' appeal pending entry of judgment in the underlying case. 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.

(“Hanjin”), one of our customers in our marine segment, filed for bankruptcy protection in South Korea and on September 1, 2016, the Korean Rehabilitation Court accepted Hanjin’s application for rehabilitation. As of October 13, 2016, we had outstanding receivables owing from Hanjin of approximately $18 million. We believe we will recover all or substantially all the amounts owed to us by Hanjin, or otherwise successfully mitigate any related losses, through the enforcement of maritime liens against vessels as well as other avenues of recovery and loss mitigation. However, there can be no assurance, that we will be able to recover all amounts owed or fully mitigate all losses. From time to time, we are under review by the Internal Revenue Service and various other domestic and foreign tax authorities with regards to income tax and indirect tax matters and are involved in various challenges and litigation in a number of countries, including, in particular, US, Brazil and South Korea, where the amounts under controversy may be significant. When we deem it appropriate and the amounts are reasonably estimable, we establish reserves for potential adjustments to our provision for income taxes and accrual of indirect taxes that may result from examinations by these 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 the federal, state, and foreign income tax liabilities and indirect tax liabilities are less than the ultimate assessment, it could result in a further charge to expense. We believe that the final outcome of these examinations, agreements, administrative or judicial proceedings will not have a material effect on our results of operations or cash flows. 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, 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 September 30, 2016, 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.
