Basis Of Presentation [Abstract]
Basis Of Presentation	1. Basis of Presentation Our consolidated financial statements include the accounts of the holding company, Atlas Air Worldwide Holdings, Inc. (“AAWW”), and its consolidated subsidiaries. AAWW is the parent company of Atlas Air, Inc. (“Atlas”), Southern Air Holdings, Inc. (“Southern Air”) and Polar Air Cargo LLC (“Old Polar”). Southern Air was acquired on April 7, 2016 (see Note 4). AAWW is also the par ent company of several subsidiaries related to our dry leasing services (collectively referred to as “Titan”) . AAWW has a 51% equity interest and 75% voting interest in Polar Air Cargo Worldwide, Inc. (“Polar”). We record our share of Polar’s results und er the equity method of accounting. The terms “we,” “us,” “our,” and the “Company” mean AAWW and all entities included in its consolidated financial statements. We provide outsourced aircraft and aviation operating services throughout the world, serving Af rica, Asia, Australia, Europe, the Middle East, North America and South America through: ( i ) contractual service arrangements, including those through which we provide aircraft to customers and value-added services, including crew, maintenance and insuranc e (“ACMI”), as well as those through which we provide crew, maintenance and insurance, but not the aircraft (“CMI”); (ii) cargo and passenger charter services (“Charter”); and (iii) dry leasing aircraft and engines (“Dry Leasing” or “Dry Lease”). The acc ompanying unaudited consolidated financial statements and related notes (the “Financial Statements”) have been prepared in accordance with the U.S. Securities and Exchange Commission (the “SEC”) requirements for quarterly reports on Form 10-Q, and conseque ntly exclude certain disclosures normally included in audited consolidated financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). All significant intercompany accounts and transa ctions have been eliminated. The Financial Statements should be read in conjunction with the audited consolidated financial statements and the notes included in the AAWW Annual Report on Form 10-K for the year ended December 31, 2015 , which inclu des additional disclosures and a summary of our significant accounting policies. The December 31, 2015 balance sheet data was derived from that Annual Report. In our opinion, the Financial Statements contain all adjustments, consisting of normal recurring items, necessary to fairly state the financial position of AAWW and its consolidated subsidiaries as of June 30, 2016 , the results of operations for the three and six months ended June 30, 2016 and 2015 , comprehensive incom e for the three and six months ended June 30, 2016 and 2015 , cash flows for the six months ended June 30, 2016 and 2015 , and shareholders’ equity as of and for the six months ended June 30, 2016 and 2015 . Our quarterly results are subject to seasonal and other fluctuations, and the operating results for any quarter are therefore not necessarily indicative of results that may be otherwise expected for the entire year. Except for per share dat a, all dollar amounts are in thousands unless otherwise noted . Certain reclassifications have been made to prior periods’ consolidated financial statement amounts and related note disclosures to conform to the current year’s presentation.

Recently Adopted Accounting Pronouncements [Abstract]
Recently Adopted Accounting Pronouncements	2. Recent Accounting Pronouncement s In March 2016, the Financial Accounting Standards Board (“FASB”) amended its accounting guidance for share-based compensation. The amended guidance changes how companies account for certain aspects of share-based payment awards to employees, including the accounting for income taxes , forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. This amended guidance is effective as of the beginning of 2017 . E arly adoption is permitted. We are currently assessing the impact the amended guidance will ha ve on our financial statements. In February 2016, the FASB amended its accounting guidance for leases. The guidance requires a lessee to recognize assets a nd liabilities on the balance sheet arising from leases with terms greater than twelve months. While lessor accounting guidance is relatively unchanged, certain amendments were made to conform with changes made to lessee accounting and recently released revenue recognition guidance. The new guidance for leas es will continue to classify them as either finance or operating, with classification affecting the pattern of expense and income recognition in the statement of operations. It also requires additional quantitative and qualitative disclosures about leasin g arrangements. The amended guidance is effective as of the beginning of 2019 . E arly adoption is permitted. We are currently assessing the impact the amended guidance will ha ve on our financial statements. In May 2014, the FASB amended its accounting gu idance for revenue recognition. The fundamental principles of the new guidance are that companies should recognize revenue in a manner that reflects the timing of the transfer of services to customers and consideration that a company expects to receive fo r the services provided. It also requires additional disclosures necessary for the financial statement us ers to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. I n August 2015, the FAS B deferred the effective date by one year to the beginning of 2018. Early adoption is permitted , but not before the beginning of 2017 . While w e are still assessing the impact the amended guidance will have on our financial statements , we expect that revenue currently recognized based on flight departure will likely be recognized over time as the services are performed .

Southern Air Holdings Acquisition	4. Southern Air Holdings Acquisition On January 15, 2016, we entered into an Agreement and Plan of Merger to acquire all the outstanding shares of Southern Air (the “ Southern Acquisition ”). Southern Air is the parent company of several subsidiaries, including Southern Air Inc. and Florida West International Airways, Inc. (“Florida West”). The Southern Acquisition provided us with immediate entry into 777 and 737 aircraft operating platforms, with the potential for developing additional business with existing and new customers of both companies. We believe the platforms provided by these aircraft will augment our ability to offer customers the broadest array of aircraft and operating services for domestic, regional and international applications. Sou thern Air currently flies five 777-200 LR F and five 737-400F aircraft unde r CMI agreements for DHL . The Southern Acquisition was completed on April 7, 2016 for total estimated consideration of $ 105.5 million, net of cash acquired, subject to working capita l and other adjustments , consisting of the following: Fair value of consideration Cash paid, net of $15,615 cash acquired $ 107,498 Estimated working capital adjustment (2,406) Estimated other adjustments 372 Total estimated consideration $ 105,464 Tangible and identifiable intangible assets acquired and liabilities assumed were recorded at fair value as of the acquisition date. The current fair values of assets acquired and liabilities assumed are considered preliminary until we obtain final information regarding their fair values. We expect to finalize the valuation as soon as practicable, but not later than one year from the acquisition date. The following table summarizes the preliminary amounts recognized for fair values of the assets ac quired and liabilities assumed as of April 7, 2016: Estimated Fair Value Accounts receivable, net $ 21,753 Prepaid expenses and other current assets 8,331 Property and equipment 6,355 Intangible assets and goodwill 63,345 Deferred income taxes 35,522 Other assets 1,498 Total assets acquired $ 136,804 Accounts payable $ 22,438 Accrued liabilities 8,902 Total liabilities assumed 31,340 Net assets acquired $ 105,464 The fair values and useful lives for all intangible assets and goodwill as of April 7, 2016 are as follows: Estimated Useful Lives Estimated Fair Value Customer relationship 16 years $ 26,280 Trade name 1.5 years 700 Goodwill Indefinite 36,365 Total intangible assets and goodwill $ 63,345 Customer relationship represents the underlying relationship and agreements with DHL. The trade name relates to the Southern Air brand. Goodwill is not deductible for tax purposes and is primarily attributable to the expanded market opportunities expected from combining the service offerings of Southern Air with ours, as well as the employee work force acquired. Southern Air’s results of operations and goodwill are reflected in our ACMI segment. Southern Air’s results of operations have been inclu ded in our unaudited consolidated statements of operations from the date of acquisition. For the three and six months ended June 30, 2016 , our consolidated results include Southern Air’s operating revenue of $ 25.7 million. For the three and six months ended June 30, 2016 , we incurred Transaction-related expenses of $ 13.3 million and $ 14.1 million, respectively, primarily related to: compensation costs, including employee termination benefits; professional fees; and integration costs associated with the acquisition. A summary of the employee termination benefit liability, which is expected to be paid by the first quarter of 2017, is as follows: Employee Termination Benefits Transaction-related expenses $ 2,667 Cash payments (1,554) Liability as of June 30, 2016 $ 1,113 The unaudited pro forma operating revenue for the three months ended June 30, 2016 and June 30, 2015 was $ 444.9 million and $ 478.0 million, respectively. The unaudited pro forma operating revenue for the six months ended June 30, 2016 and June 30, 2015 was $ 889.0 million and $ 942.6 million, respectively. This pro forma information has been calculated as if the acquisition had taken place on January 1, 2015 and is not necessarily indicative of the net sales that actually would have been achieved. This information includes adjustments to conform with our accounting policies. The earnings of Southern Air were not material and, accordingly, pro forma and actual earnings information have not been presented. As part of integrating Southern Air, management decided and committed to pursue a plan to sell Florida West.

Warrant abstract
Amazon Warrant	6. Amazon In May 2016, we entered into agreements with Amazon.com, Inc. and its subsidiary, Amazon Fulfillment Services, Inc., (collectively “Amazon”), which will include CMI operation of 20 Boeing 767-300 freighter aircraft for Amazon by Atlas, as well as Dry Leasing by Titan . The Dry Leases will have a term of ten years, while the CMI operations will be for seven years (with extension provisions for a total term of ten years). The first aircraft is expected to be placed in service duri ng the third quarter of 2016 with the remainder expected to be placed in service through 2018. In conjunction with these agreements, we granted Amazon a warrant providing the right to acquire up to 20% of our outstanding common shares , after giving effect to the issuance of shares pursuant to the warrants, at an exercise price of $ 37.50 per share. A portion of the warrant, representing the right to purchase 3.75 million shares, vested immediately upon issuance of the warrant and the remainder of the warran t, representing the right to purchase 3.75 million shares, will vest proportionately as the underlying operations for aircraft 11-20 commence. The warrant will be exercisable in accordance with its terms through 2021 . The agreements also provide incenti ves for future growth of the relationship as Amazon may increase its business with us. In that regard, we granted Amazon a warrant to acquire up to an additional 10% of our outstanding common shares , after giving effect to the issuance of shares pursuant to the warrants, for an exercise price of $ 37.50 per share. This warrant to purchase 3.75 million shares will vest in conjunction with payments by Amazon for additional business with us. The warrant will be exercisable in accordance with its terms throug h 2023 . A $ 92.9 million fair value of the vested portion of the warrant issued to Amazon as of May 4, 2016 was recorded as a warrant liability within Financial instruments and o ther l iabilities (the “Amazon Warrant”) . The initial fair value of the warra nt was recognized as a customer incentive asset within Deferred costs and other assets, net and will b e amortized as a reduction of revenue in proportion to the amount of revenue recognized. The Amazon Warrant liability is marked-to-market at the end of e ach reporting period with changes in fair value recorded in Other non-operating expenses . We utilized a Monte Carlo simulation approach to estimate the f air v alue of the Amazon W arrant which requires inputs such as our common stock price, strike price, es timated stock price volatility and risk-free interest rate, among other assumptions. During the three and six month periods ended June 30, 2016, we recognized an unrealized gain on the Amazon Warrant of $26.5 million. The fair value of the Amazon W arrant liability was $ 66.4 million as of June 30, 2016.

Debt [Abstract]
Debt	8. Debt Term Loans In February 2016 , we borrowed $ 14.8 million related to the conversion of a 767-300BDSF aircraft under a n eight -year term loan with a final payment of $ 3.8 million due in February 2024 (the “First 2016 Term Loan”). The First 2016 Term Loan, which is secured by a mortgage against aircraft tail number N 642 GT , contains customary covenants and events of default and accrues interest at a fixed rate of 3. 19 %, with principal and interest payable month ly. In June 2016 , we borrowed $ 70.0 m illion under a five -year term loan with a final payment of $ 30.2 million due in June 2021 (the “Second 2016 Term Loan”). The Second 2016 Term Loan, which is secured by a mortgage against six spare GEnx engines , contains customary covenants and events of default and accrues interest at a n initial variable rate of 2.93 %, with principal and interest payable month ly. The Second 2016 Term Loan was converted to a fixed rate loan in July 2016 at a rate of 3.12 %, with principal and interest payable quarterly. Convertible Notes In June 2015, we issued $ 224.5 million aggregate principal amount of convertible senior notes (the “Convertible Notes”) in a n underwritten public offering. The Convertible Notes are senior unsec ured obligations and accrue interest payable semiannually on June 1 and December 1 of each year at a fixed rate of 2.25%. The Convertible Notes will mature on June 1, 2022, unless earlier converted or repurchased pursuant to their terms. Proceeds from th e issuance of the Convertible Notes were used to refinance higher-rate debt related to five 747-400 freighter aircraft that had an average cash coupon of 8.1%. As of June 30, 2016 , the remaining life of the Convertible Notes is 6.3 years and consisted of the following: Liability component: Gross proceeds $ 224,500 Less: debt discount, net of amortization (46,218) Less: debt issuance cost, net of amortization (4,488) Net carrying amount $ 173,794 Equity component (1) $ 52,903 (1) Included in Additional paid-in capital on the consolidated balance sheet as of June 30, 2016.

Income Taxes [Abstract]
Income Taxes	9. Income Taxes Our effective income tax rate s were 26.4% and 31.0% for the three months ended June 30, 2016 and June 30, 2015 , respectively. Our effective income tax rate s were 26.8% and 25.6% for the six months ended June 30, 2016 and June 30, 2015 , respectively. The effective rates for both periods differed from the U.S. federal statutory rate due to the income tax impact of foreign operations taxed at different rates, our a ssertion to indefinitely reinvest the net earnings of certain foreign subsidiaries outside the U.S., U.S. state income taxes, the nondeductibility of certain expenses for tax purposes, adjustments to our liability for uncertain tax positions, and the relat ionship of these items to our projected operating results for the year. In addition, t he effective rate for the six months ended June 30, 2015 differed from the U.S. federal statutory rate primarily due to an income tax benefit of $ 4.0 million , net of reserves, related to extraterritorial income (“ETI”) from leasing certain of our aircraft. For interim accounting purposes, we recognize income taxes using an estimated annual effective tax rate.

Financial Instruments [Abstract]
Financial Instruments	10 . Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Inputs used to measure fair value are classified in the following hierarchy: Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 Other inputs that are observable directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, or inactive quoted prices for identical assets or liabilities in inactive markets; Level 3 Unobservable inputs reflecting assumptions about the inputs used in pricing the asset or liability. We endeavor to utilize the best available informa tion to measure fair value. The carrying value of Cash and cash equivalents, Short-term investments and Restricted cash is based on cost, which approximates fair value. Long-term investments consist of debt securities for which we have both the ability a nd the intent to hold until maturity. These investments are classified as held-to-maturity and reported at amortized cost. The fair value of our Long-term investments is based on a discounted cash flow analysis using the contractual cash flows of the inv estments and a discount rate derived from unadjusted quoted interest rates for debt securities of comparable risk. Such debt securities represent investments in Pass-Through Trust Certificates (“PTCs”) related to enhanced equipment trust certificates (“EE TCs”) issued by Atlas in 1998, 1999 and 2000. The fair value of our term loans, notes guaranteed by the Export-Import Bank of the United States (“Ex-Im Bank”) and EETCs are based on a discounted cash flow analysis using current borrowing rates for instruments with similar terms. The fair value of our Convertible Notes is based on unadjusted quoted market prices for these securities. The fair value of the Amazon Warrant is based on a Monte Carlo simulation which requires inputs such as our common stock price, strike price, estimated stock price volatility, and risk-free interest rate, among other assumptions . The following table summarizes the carrying value , estimated fair value and classification of our financial instruments as of: June 30, 2016 Carrying Value Fair Value Level 1 Level 2 Level 3 Assets Cash and cash equivalents $ 155,247 $ 155,247 $ 155,247 $ - $ - Short-term investments 1,983 1,983 - - 1,983 Restricted cash 13,098 13,098 13,098 - - Long-term investments and accrued interest 33,857 40,389 - - 40,389 $ 204,185 $ 210,717 $ 168,345 $ - $ 42,372 Liabilities Term loans $ 1,050,880 $ 1,093,669 $ - $ - $ 1,093,669 Ex-Im Bank guaranteed notes 653,580 696,160 - - 696,160 EETCs 24,105 28,526 - - 28,526 Convertible Notes 173,794 216,081 216,081 - - Amazon Warrant 66,413 66,413 - 66,413 - $ 1,968,772 $ 2,100,849 $ 216,081 $ 66,413 $ 1,818,355 December 31, 2015 Carrying Value Fair Value Level 1 Level 2 Level 3 Assets Cash and cash equivalents $ 425,950 $ 425,950 $ 425,950 $ - $ - Short-term investments 5,098 5,098 - - 5,098 Restricted cash 12,981 12,981 12,981 - - Long-term investments and accrued interest 37,604 45,867 - - 45,867 $ 481,633 $ 489,896 $ 438,931 $ - $ 50,965 Liabilities Term loans $ 1,013,265 $ 1,049,785 $ - $ - $ 1,049,785 Ex-Im Bank guaranteed notes 689,720 715,890 - - 715,890 EETCs 28,022 30,074 - - 30,074 Convertible Notes 170,300 185,325 185,325 - - $ 1,901,307 $ 1,981,074 $ 185,325 $ - $ 1,795,749 The following table presents the carrying value, gross unrealized gain (loss) and fair value of our long-term investments and accrued interest by contractual maturity as of : June 30, 2016 December 31, 2015 Carrying Value Gross Unrealized Gain (Loss) Fair Value Carrying Value Gross Unrealized Gain (Loss) Fair Value Debt securities Due after one but within five years 33,857 6,532 40,389 37,604 8,263 45,867 Total $ 33,857 $ 6,532 $ 40,389 $ 37,604 $ 8,263 $ 45,867

Segment Reporting [Abstract]
Segment Reporting	11 . Segment Reporting Our business is organized into three operating segments based on our service offerings: ACMI, Charter and Dry Leasing. All segments are directly or indirectly engaged in the business of air transportation services but have different commercial and economic characteristics. Each operating segment is separately reviewed by our chief operating decision maker to assess operating results and make resource allocation decisions. We do not ag gregate our operating segments and , therefore , our operating seg ments are our reportable segments. We use an economic performance metric (“Direct Contribution”) that shows the profitability of each segment after allocation of direct operating and ownership costs. Direct Contribution represents Income from continuing operations before income t axes excluding the following: Special charges, Transaction -related expenses, nonrecurring items, Losses (gains) on the disposal of aircraft, Losses on early extinguishment of debt, Unrealized losses (gains) on financial instruments, Gains on investments an d U nallocated income and expenses, net . Direct operating and ownership costs include crew costs, maintenance, fuel, ground operations, sales costs, aircraft rent, interest expense on the portion of debt used for financing aircraft, interest income on debt securities and aircraft depreciation. Unallocated income and expenses , net include corporate overhead, nonaircraft depreciation, noncash expense s and income, interest expense on the portion of debt used for general corporate purposes, interest income on nondebt securities , capitalized interest, foreign exchange gains and losses, other revenue and other non - operating costs. T he following table sets forth Operating Revenue and Direct Contribution for our reportable segments reconciled to Operating Income and Income from continuing operations before i ncome t axes: For the Three Months Ended For the Six Months Ended June 30, 2016 June 30, 2015 June 30, 2016 June 30, 2015 Operating Revenue: ACMI $ 211,722 $ 189,255 $ 394,462 $ 378,302 Charter 202,451 235,436 404,754 455,574 Dry Leasing 25,066 27,401 53,258 59,320 Other 4,033 3,741 9,413 7,482 Total Operating Revenue $ 443,272 $ 455,833 $ 861,887 $ 900,678 For the Three Months Ended For the Six Months Ended June 30, 2016 June 30, 2015 June 30, 2016 June 30, 2015 Direct Contribution: ACMI $ 45,490 $ 51,157 $ 70,230 $ 91,059 Charter 24,856 25,019 45,633 55,478 Dry Leasing 6,878 10,894 17,286 26,419 Total Direct Contribution for Reportable Segments 77,224 87,070 133,149 172,956 Add back (subtract): Unallocated income and expenses, net (58,503) (45,320) (106,048) (94,304) Loss on early extinguishment of debt - - (132) - Unrealized gain on financial instruments 26,475 - 26,475 - Special charge - (499) (6,631) 69 Transaction-related expenses (16,788) - (17,581) - Loss on disposal of aircraft - (114) - (1,323) Income from continuing operations before income taxes 28,408 41,137 29,232 77,398 Add back (subtract): Interest income (1,405) (4,425) (3,009) (8,913) Interest expense 20,938 25,033 42,240 49,581 Capitalized interest (690) (177) (1,047) (203) Loss on early extinguishment of debt - - 132 - Unrealized gain on financial instruments (26,475) - (26,475) - Other expense (income), net 48 (284) (192) 391 Operating Income $ 20,824 $ 61,284 $ 40,881 $ 118,254 We are exposed to a concentration of revenue from the U.S. Military Air Mobility Command ( the “AMC”) and Polar (see Note 3 for further discussion regarding Polar) .

Labor And Legal Proceedings [Abstract]
Legal Proceedings	12. Legal Proceedings Matters Related to Alleged Pricing Practices T he Company and Old Polar were named defendants, along with a number of other cargo carriers, in several class actions in the U . S . arising from allegations about the pricing practices of Old Polar and a number of air cargo carriers. These actions were all centralized in the U . S . District Court for the Eastern District of New York. Polar was later joined as an additional defendant. The consolidated complaint alleged , among other things, that the defendants, including the Company and Old Polar, manipulated the market price for air cargo services sold domestically and abroad through the use of surcharges, in violation of U . S . , state, and European Union antitrust laws. The suit sought treble damages and attorneys’ fees. On January 7, 2016, the Company, Old Polar, and Polar entered into a settlement agreement to settle all claims by participating class members against the Company, Old Polar and Polar. T he Company, Pola r, and Old Polar deny any wrongdoing, and there is no admission of any wrongdoing in the settlement agreement. Pursuant to the settlement agreement, the Company, Old Polar and Polar have agreed to make installment payments over three years to settle the p laintiffs’ claims, with payments of $ 35.0 million paid on January 15, 2016, $ 35.0 million due on or before January 15, 2017, and $ 30.0 million due on or before January 15, 2018. The U . S . District Court for the Eastern District of New York issued an order granting preliminary approval of the settlement on January 12, 2016. The settlement is still subject to final court approval. In the United Kingdom, several groups of named claimants have brought suit against British Airways in connection with the same alleged pricing practices at issue in the proceedings described above and are seeking damages allegedly arising from that conduct. British Airways has filed claims in the lawsuit against Old Polar and a number of air cargo carriers for contribution should British Airways be found liable to claimants. Old Polar’s formal statement of defense was filed on March 2, 2015. On October 14, 2015, the U.K. Court of Appeal released decisions favorable to the defendant and contributory defendants on two matters under appeal. Permission has been sought to appeal the U.K. Court of Appeal's decisions to the U.K. Supreme Court. In December 2015, certain claimants settled with British Airways removing a significant portion of the claim against British Airways and therefore reducing the potential contribution required by the other airlines, including Old Polar. On December 16, 2015, the European General Court released decisions annulling decisions that the European Commission made against the majority of the air cargo carriers. The European Commission has not appealed the General Court decision, but may still reopen its investigation or reissue a revised decision, either of which would have a significant impact on the proceedings in the U.K. court. Future procedures, including the pretrial disclosure process, are undergoing court review. We are unable to reasonably predict the outcome of the litigation. In the Netherlands, Stichting Cartel Compensation, successor in interest to claims of various shippers, has filed suit in the district court in Amsterd am against British Airways, KLM, Martinair , Air France, Lufthansa and Singapore Airlines seeking recovery for damages purportedly arising from the same pricing practices at issue in the proceedings described above. In response, British Airways, KLM, Marti nair , Air France and Lufthansa filed third-party indemnification lawsuits against Old Polar and Polar seeking indemnification in the event the defendants are found to be liable in the main proceedings. Old Polar and Polar entered their initial court appea rances on September 30, 2015. Like the U.K. proceedings, the Netherlands proceedings are likely to be affected and have been delayed by the European General Court decisions of December 16, 2015. We are unable to reasonably predict the outcome of the liti gation. If the Company, Old Polar or Polar were to incur an unfavorable outcome in connection with the U.K. or Netherlands proceedings, such outcome may have a material adverse impact on our business, financial condition, results of operations or cash flows. We are unable to reasonably estimate a range of possible loss for such matters at this time . Brazilian Customs Claim Old Polar was cited for two alleged customs violations in Sao Paulo, Brazil, relating to shipments of goods dating back to 1999 and 2000. Each claim asserts that goods listed on the flight manifest of two separate Old Polar scheduled service flights were not on board the aircraft upon arrival and therefore were improperly brought into Brazil. The two claims, which also seek unpaid c ustoms duties, taxes and penalties from the date of the alleged infraction, are approximately $ 6.1 million in aggregate based on June 30, 2016 exchange rates. In both cases, we believe that the amounts claimed are substantially overstated d ue to a calculation error when considering the type and amount of goods allegedly missing, among other things. Furthermore, we may seek appropriate indemnity from the shipper in each claim as may be feasible. In the pending claim for one of the cases, we have received an administrative decision dismissing the claim in its entirety, which remains subject to a mandatory appeal by the Brazil customs authorities. As required to defend such claims, we have made deposits pending resolution of these matters. T he balances were $ 4.8 million as of June 30, 2016 and $ 3.8 million as of December 31, 2015 , and are included in Deposits and other assets. We are currently defending these and other Brazilian customs claims and the ultimate disposition of these claims, either individually or in the aggregate, is not expected to materially affect our financial condition, results of operations or cash flows. Accruals As of June 30, 2016, the Company had a remaining accrual of $65.0 million related to the U.S. class action settlement. During the second quarter of 2016, the Company recorded an accrual of $6.7 million within Other operating expense in the consolidated st atement of operations related to pending litigation outside of the U.S. Other We have certain other contingencies incident to the ordinary course of business. Management believes that the ultimate disposition of such other contingencies is not expected to materially affect our financial condition, results of operations or cash flows.
